Description

A foaming device and a related water outlet device

Technical Field

The present application relates to the field of water outlet devices, and in particular to a bubble generating device and a related water outlet device.

Background Art

It is known that the bubbler is generally installed at the water outlet end of the water outlet pipe and connected to the water outlet pipe through a thread. Since the bubbler itself is also easily blocked by solid impurities in the water, it is necessary to disassemble the bubbler for backwashing. When disassembling the bubbler, the user needs to loosen it in the opposite direction, but often because the user does not know which direction to loosen the bubbler, the user may tighten it more and more, and finally have to use a tool to unscrew the bubbler, thereby damaging the outer surface of the bubbler or the water outlet pipe. Furthermore, since the bubbler is exposed outside the water outlet pipe, a seam will be formed between the bubbler and the water outlet pipe, and the seam is easy to harbor dirt.

Embodiment 1

Embodiment 1 relates to a bubble generating device 100 and a water outlet device 1000. The bubble generating device 100 is used to be connected to a water outlet pipe 200 of the water outlet device 1000 (see FIG. 11 ).

See Figures 1 to 3. As shown in the figures, the foaming device 100 includes a connecting component 10 and a foamer 3. The connecting component 10 includes a mounting seat 1 and a sliding block 2.

The shape and structure of the mounting base 1 are shown in Figures 4 and 5. As shown in the figure, the mounting base 1 includes a mounting base body 11 and a mounting base cover body 12. In Figure 4, the mounting base body 11 includes a shell 111, a mounting ring 112 and a plurality of connecting ribs 113. The shell 111 is located in the center of the mounting base body 11, and is coaxially surrounded by a mounting ring 112. Each connecting rib 113 extends radially to connect the shell 111 and the mounting ring 112 as a whole. As shown in Figure 4, the outer wall of the mounting ring 112 is provided with an external thread that matches the internal thread on the inner wall of the water outlet pipe 200. The intervals between the connecting ribs 113 form a plurality of water holes 114. In this embodiment, the water holes 114 are symmetrically arranged around the shell 111 in the radial direction, so that the user can insert the fork-shaped tool symmetrically therebetween, assemble the mounting ring 112 to the inner wall of the water outlet pipe 200 and tighten it. The structure of the shell 111 is shown in FIG5 , which is generally annular and has a stepped hole in the axial direction, wherein the large hole is on the top and the small hole is on the bottom, and an upward limiting surface 133 is provided between the large hole and the small hole. As shown in FIG4 and FIG5 , the mounting seat cover 12 is covered on the upper end of the shell 111 and is connected to the shell 111 by snapping. After the mounting seat cover 12 is connected to the shell 111, a seat body 13 with an opening downward is formed. The shape of the seat body 13 is cylindrical, and the cylindrical cavity of the seat body 13 is divided into two parts by the limiting surface 133, wherein the part above the limiting surface 133 forms a first chamber 131, and the part below the limiting surface 133 forms a second chamber 132. Since the shell 111 is coaxial with the mounting ring 112, and the mounting ring 112 is threadedly matched with the water outlet pipe 200, the axis of the seat body 13 coincides with the axis of the water outlet pipe 200. The top surface of the mounting seat cover 12 forms a first parking position of the seat body 13 , and the limiting surface 133 on the mounting seat body 11 forms a second parking position of the seat body 13 .

As shown in FIG3 , the sliding block 2 includes a slider 21, a clamping block 22 and a screw 23. The structure of the slider 21 is shown in FIG6 . As shown in FIG6 , the slider 21 is provided with a cylinder 211 with an opening facing upward, the bottom of the cylinder 211 extends downward and is provided with a connecting portion 212, and the upper end of the outer wall of the cylinder 211 is provided with a boss 213. The lower surface of the boss 213 forms a step surface 214. In the center of the slider 2, a connecting hole 215 is provided through the connecting portion 212 and the bottom of the cylinder 211, and the connecting hole 215 is provided with an internal thread. The outer wall of the boss 213 is provided with a sealing ring groove, and a sealing ring 216 is installed in the sealing ring groove. The shape of the clamping block 22 is shown in FIG7 . As shown in FIG7 , the clamping block 22 is provided with a cylindrical body 221, and the diameter of the body 221 is substantially the same as the diameter of the cylinder 211 of the slider 21. On the lower surface 222 of the body, four elastic claws 223 are arranged around the axis in the circumferential direction. The elastic claws 223 are opened outwards when not pressed, and the free ends thereof are provided with a clamping head 224 extending inwards. A through hole is arranged in the center of the body 221. The shape of the screw 23 is shown in FIG3 .

The shape of the bubbler 3 is shown in FIG8 . As shown in FIG8 , the bubbler 3 is provided with a push rod 31 extending upward, and a slot 32 is provided on the side wall of the push rod 31. A lip seal ring 34 opening upward is provided on the side wall 33 of the bubbler. A water inlet is provided on the upper surface of the bubbler 3, and a water outlet is provided on the lower surface. The water inlet is suitable for introducing water flowing through the water hole 114, and the water outlet is suitable for outputting bubble water. Since the structure of the bubbler 3 is known and is not improved in the present application, it will not be described in detail.

The state of the foaming device 100 after the connection is completed is shown in Figure 9. Among them, the screw 23 passes through the through hole on the block 22 and is screwed into the connection hole 215 on the slider 21 to fasten the slider 21 and the block 22 together. The boss 213 of the slider 21 is located in the first chamber 131 of the seat body 13, and the cylinder 211 of the slider 21 and the body 221 of the block 22 extend into the second chamber 132 of the seat body 13. The outer wall of the boss 213 is matched with the sliding clearance of the side wall of the first chamber 131, and the sealing ring 216 is placed therebetween to increase the friction between the two so that the slider 213 can stop. The cylinder 211 and the body 221 are matched with the sliding clearance of the side wall of the second chamber 132. As a result, a sliding connection relationship is established between the sliding block 2 and the seat body 13. In FIG9 , the sliding block 2 is in the first position, the upper end surface of the slider 21 abuts against the bottom surface of the mounting seat cover 12 (i.e., the first parking position of the seat 13), and the elastic claw 223 retracts into the second chamber 132 of the seat 13. Due to the pressure of the side wall of the second chamber 132 against the outer edge of the elastic claw 223, the elastic claw 223 retracts inward and establishes a snap-fit relationship with the slot 32 of the bubbler 3. The bubbler 3 is fixed relative to the mounting seat 1 because it is caught by the elastic claw 223. At this time, due to the friction of the sealing ring 216, the sliding member 2 will not slide down due to the gravity of the bubbler 3 and the pressure of the water flow.

In the frothing device 100, the state in which the connecting assembly 10 is separated from the frothing device 3 is shown in Fig. 10. In Fig. 10, the sliding block 2 is in the second position, the step surface 214 of the boss 213 abuts against the limiting surface 133 of the seat body 13 (i.e., the second parking position of the seat body 13), and the elastic claw 223 is completely extended out of the second chamber 132 of the seat body 13. Due to the loss of the pressure of the side wall of the second chamber 132, the elastic claw 223 is deformed and restored to open outward, and the engagement relationship with the slot 32 of the frothing device 3 is broken, and the frothing device 3 is released due to the loss of the clamping of the elastic claw 223.

The connection assembly 10 is assembled as follows: first, the slider 21 is placed into the large hole from the top of the mounting seat body 11 with the connection portion 212 facing downward, and then the mounting seat cover 12 is clamped with the mounting seat body 11. Then, the clamp block 22 is inserted into the second chamber 132 with the body 221 facing upward, and the clamp block 22 is connected to the slider 21 with the screw 23. At this point, the connection assembly 10 is assembled.

The shape of the water outlet device 1000 is shown in FIG11. As shown in FIG11, the water outlet device 1000 includes a water outlet pipe 200 and a bubbler 100. The connection relationship between the water outlet pipe 200 and the bubbler 100 is shown in FIG12 and FIG13. As shown in FIG12 and FIG13, a limit ring 201 is provided at the position of the water outlet pipe 200 near the water inlet and outlet ends, a water through hole 202 is provided at the center of the limit ring 201, and an internal thread is provided on the inner wall of the water outlet pipe 200 below the limit ring 201. The external thread of the mounting ring 112 of the connecting assembly 10 is screwed with the internal thread of the water outlet pipe 200, so that the mounting seat 1 and the water outlet pipe 200 are fixedly connected together. In Fig. 12, the sliding block 2 is in the first position, at which time the bubbler 3 is captured by the elastic claw 223, a portion of which is located inside the water outlet pipe 200, and another portion is located outside the water outlet pipe 200, and the lip seal 34 is located inside the water outlet pipe 200, so that the bubbler 3 is sealed and connected to the water outlet pipe 200 without water leakage. In Fig. 13, the sliding block 2 is in the second position, at which time the bubbler 3 is released by the elastic claw 223, a majority of which is located outside the water outlet pipe 200, a small portion is located inside the water outlet pipe 200, and the lip seal 34 is located outside the water outlet pipe 200.

The method of installing the connection assembly 10 to the water outlet pipe 200 is as follows: first, complete the assembly of the connection assembly 10, and then extend the connection assembly 10 into the water outlet pipe 200 with the mounting seat cover 12 facing upward, until the external thread of the mounting ring 112 touches the internal thread of the water outlet pipe 200. Insert the fork end of the fork-shaped installation tool into the symmetrical water holes 114, and rotate the fork-shaped installation tool until the upper end surface of the mounting ring 112 hits the lower surface of the limit ring 201, that is, the threaded connection between the mounting ring 112 and the water outlet pipe 200 is completed, thereby installing the connection assembly 10 to the water outlet pipe 200.

The method of connecting the bubbler 3 to the connection assembly 10 is as follows: the bubbler 3 is extended into the water outlet pipe 200 with the push rod 31 upward, and the push rod 31 presses against the lower surface 222 of the body of the block 22, and the state at this time is shown in Figure 13. Continue to push the bubbler 3 upward, so that the push rod 31 pushes the sliding block 2 to move upward until the sliding block 2 moves to the first position, and the state at this time is shown in Figure 12, that is, the connection of the bubbler 3 is completed. After the bubbler 3 is connected, open the valve of the water outlet device 1000, and the water flows through the water hole 202 on the limit ring 201, and then through the water hole 114 to reach the water inlet of the bubbler 3, and then flows out from the water outlet of the bubbler 3 after passing through the bubbler 3. Since the lip seal ring 34 is placed between the side wall 33 of the bubbler and the inner wall of the water outlet pipe 200, the water will not flow out from the gap between the two.

The method of removing the bubbler 3 from the connection assembly 10 is as follows: grab the portion of the bubbler 3 exposed from the water outlet pipe 200 and pull it downward, so that the bubbler 3 drives the sliding block 2 to move downward until the sliding block 2 moves to the second position, and the state at this time is shown in Figure 13. Continue to pull the bubbler 3 downward to completely separate the bubbler 3 from the water outlet pipe 200, and the bubbler 3 is removed. After the bubbler 3 is removed, it can be connected to the connection assembly 10 through the steps described above after backwashing.

Of course, this embodiment is not the only embodiment, and in particular, a pull ring extending downward can be provided on the lower surface of the bubbler 3, so that the screw connection position of the mounting ring 112 and the water outlet pipe 200 can be set, so that the water outlet of the bubbler 3 is located in the water outlet pipe 200, without affecting the user's removal of the bubbler 3. Specifically, the bubbler 3 can be removed from the water outlet pipe 200 by pulling the aforementioned pull ring.

It can be seen from the above description that the bubbler 3 can be easily disassembled from the water outlet pipe 200 in this embodiment.

The width of the protrusion 44 is suitable for inserting into the anti-rotation groove 135. A hooking portion 45 extending downward is provided on the lower end surface of the sleeve body 41. The hooking portion 45 is suitable for hooking and connecting with the hanging portion 219. An inner bevel 46 is provided on the lower end surface of the convex ring 43; an outer bevel 47 is provided on the lower end surface of the protrusion 44. In this embodiment, the inner bevel 46 and the outer bevel 47 are on the same plane, but they play different roles and are not necessary. The inner bevel 46 is opposite to the third bevel 218, and the outer bevel 47 is opposite to the first bevel 138 and the second bevel 136.

In this embodiment, the elastic member 5 includes a spring 51 and a gasket 52 as shown in FIG. 3 .

The structure of the connection assembly 10 after assembly is shown in Figures 19 and 20. As shown in the figure, similar to the first embodiment, the boss 213 of the slider 21 is located in the first chamber 131 of the seat body 13, and the cylinder 211 of the slider 21 and the body 221 of the block 22 extend into the second chamber 132 of the seat body 13. The outer wall of the boss 213 is matched with the sliding clearance of the side wall of the first chamber 131, and the cylinder 211 and the body 221 are matched with the sliding clearance of the side wall of the second chamber 132, thereby establishing a sliding connection relationship between the sliding block 2 and the seat body 13. The difference between this embodiment and the first embodiment is that since the anti-rotation block 217 extends into the anti-rotation groove 135 of the seat body 13, a anti-rotation matching relationship is also established between the sliding block 2 and the seat body 13. In this embodiment, the hooking portion 45 of the rotating sleeve 4 is hooked and connected with the hanging portion 219 of the slider 21, so that an axial limit connection is established between the rotating sleeve 4 and the slider 2, that is, the position between the two is limited, and when the position between the two reaches the maximum value of the limited range, force transmission is established between the two. In this embodiment, the lower end surface of the gasket 52 abuts against the upper end surface of the hanging portion 219 of the slider 21. One end of the spring 51 abuts against the mounting seat cover 12, and the other end abuts against the upper end surface of the gasket 52.

The assembly method of the connection component 10 is as follows: first, the slider 21 is placed into the large hole from the top of the mounting seat body 11 with the connection portion 212 facing downward, and the anti-rotation block 217 is inserted into the anti-rotation groove 135. Then, the rotating sleeve 4 is inserted into the cylinder cavity of the cylinder 211 of the slider 21 with the hook portion 45 facing downward, until the hook portion 45 is hooked and connected with the hanging portion 219. Then, the gasket 52 is placed on the upper end surface of the hanging portion 219 through the center hole 42 of the rotating sleeve 4. Then, the lower end of the spring 51 passes through the center hole 42 of the rotating sleeve 4 and abuts against the upper end surface of the gasket 52. Then, the mounting seat cover 12 is clamped with the mounting seat body 11, so that the upper end of the spring 51 abuts against the mounting seat cover 12. Then, the clamping block 22 is inserted into the second chamber 132 with the body 221 facing upward, and the clamping block 22 is connected to the slider 21 with the screw 23. At this time, the assembly of the connection component 10 is completed.

In this embodiment, the bubbler 3 is no different from the bubbler 3 in the first embodiment, and will not be described in detail here.

FIG19 shows the structure of the foaming device 100 in this embodiment when the sliding block 2 is in the first position. As shown in FIG19 , at this time, the protrusion 44 of the rotating sleeve 4 is parked at the higher tooth bottom 137. Since the sliding block 2 and the rotating sleeve 4 are axially limitedly connected to each other, and the sliding block 2 is pushed downward by the elastic member 5, the sliding block 2 is parked at the first position. At this time, the elastic claw 223 is retracted into the second chamber 132. Due to the pressure of the side wall of the second chamber 132 on the outer edge of the elastic claw 223, the elastic claw 223 is retracted inwardly and establishes a clamping relationship with the clamping groove 32 of the foamer 3. The foamer 3 is fixed relative to the mounting seat 1 because it is caught by the elastic claw 223.

Fig. 20 shows the structure of the foaming device 100 in this embodiment when the sliding block 2 is in the first position. As shown in Fig. 20, at this time, the protrusion 44 of the rotating sleeve 4 is parked in the lower position of the anti-rotation groove 135. Since the sliding block 2 and the rotating sleeve 4 are axially limited and connected to each other, and the sliding block 2 is pushed downward by the elastic member 5, the sliding block 2 is parked in the second position. At this time, the elastic claw 223 is completely extended out of the second chamber 132 of the seat body 13. Due to the loss of the pressure of the side wall of the second chamber 132, the elastic claw 223 is deformed and restored to open outward, and the clamping relationship with the clamping groove 32 of the bubbler 3 is broken. The bubbler 3 is released due to the loss of the clamping of the elastic claw 223.

The method of switching the sliding block 2 between the first position and the second position is explained in detail below.

The initial position is set as shown in FIG. 20 , and the sliding block 2 is in the second position, and the mounting seat 1 is set to be fixed. At this time, the push rod 31 of the bubbler 3 is pressed against the lower surface 222 of the body, and the elastic claw 223 is in an open state, but it is directly opposite to the slot 32 on the push rod 31. If the user wants to connect the bubbler 3 to the connecting assembly 10, the bubbler 3 can be pushed upward, and the push rod 31 presses the sliding block 2 to overcome the elastic force of the elastic member 5 and move upward until the third inclined surface 218 presses the inner inclined surface 46. Since the third inclined surface 218 is opposite to the inner inclined surface 46, the inclined surface cooperates to convert the axial push force into a rotational force. Since the sliding block 2 is in a non-rotating cooperation with the mounting seat 1, the rotating sleeve 4 is forced to rotate and move upward during the rotation process. During this process, the elastic claw 223 has retracted into the second chamber 132, and a clamping relationship with the slot 32 is established. The user no longer pushes against the bubbler 3, and the elastic restoring force of the elastic member 5 takes effect, driving the sliding block 2 to move downward. When the distance between the sliding block 2 and the rotating sleeve 4 reaches the limit, the sliding block 2 drives the rotating sleeve 4 to move downward until the outer bevel 47 presses against the second bevel 136. Since the second bevel 136 is opposite to the outer bevel 47, the bevel cooperates to convert the axial push force into a rotational force, thus forcing the rotating sleeve 4 to rotate and move upward during the rotation process until the protrusion 44 slides into the tooth bottom 137 and stops at the tooth bottom 137 (i.e., the first stop position). At this time, since the sliding block 2 is axially limitedly connected to the rotating sleeve 4, the sliding block 2 stops at the first position, and the bubbler 3 is caught by the connecting assembly 10.

If the user wants to remove the bubbler 3 from the connecting assembly 10, the bubbler 3 is also pushed upward, and the push rod 31 presses the sliding block 2 to overcome the elastic force of the elastic member 5 and move upward until the third inclined surface 218 presses the inner inclined surface 46. Since the third inclined surface 218 is opposite to the inner inclined surface 46, the inclined surfaces cooperate to convert the axial pushing force into a rotational force. Since the sliding block 2 is in a rotation-stopping cooperation with the mounting seat 1, the rotating sleeve 4 is forced to rotate and move upward during the rotation process. During this process, the elastic claw 223 is always engaged with the slot 32. The user no longer pushes against the bubbler 3, and the elastic restoring force of the elastic member 5 takes effect, driving the sliding block 2 to move downward. When the distance between the sliding block 2 and the rotating sleeve 4 reaches the limit, the sliding block 2 drives the rotating sleeve 4 to move downward until the outer bevel 47 switches to press against the first bevel 138. Since the first bevel 138 and the outer bevel 47 are opposite, the bevel cooperates to convert the axial push force into a rotational force, thereby forcing the rotating sleeve 4 to rotate and move upward during the rotation process, until the protrusion 44 slides into the stop groove 135 and stops in the stop groove 135 (i.e., the second stop position), located above the stop block 217. The stop block 217 then abuts against the limiting surface 133. At this time, the sliding block 2 is parked at the second position. In the above process, the elastic claw 223 extends out of the second chamber 132 and opens outward, disengaging from the card slot 32, and the bubbler 3 is able to be separated from the connecting assembly 10.

The shape of the water outlet device 1000 is shown in FIG21. As shown in FIG21, the water outlet device 1000 includes a water outlet pipe 200 and a bubbler 100, wherein the bubbler 100 is completely placed in the water outlet pipe 200 and cannot be seen from the appearance. The connection relationship between the water outlet pipe 200 and the bubbler 100 is shown in FIG22. As shown in FIG22, a limit ring 201 is provided at the position of the water outlet pipe 200 near the water inlet and outlet ends, a water hole 202 is provided at the center of the limit ring 201, and an internal thread is provided on the inner wall of the water outlet pipe 200 below the limit ring 201. The external thread of the mounting ring 112 of the connecting component 10 is screwed with the internal thread of the water outlet pipe 200, and the mounting seat 1 is fixedly connected to the water outlet pipe 200. At this time, the bubbler 3 can be connected to the connecting component 10 or removed from the connecting component 10 in the aforementioned manner. FIG21 shows a simple process of establishing a connection with the connecting component 10. After this process is completed, the sliding block 2 is in the first position, at which time the bubbler 3 is caught by the elastic claw 223 and is completely located in the water outlet pipe 200. If the user wants to remove the bubbler 3 from the water outlet pipe 200 for cleaning, he only needs to press the bubbler 3 upwards. As mentioned above, the bubbler 3 is released by the elastic claw 223. Moreover, at this time, since the sliding block 2 is in the lower second position, the bubbler 3 is pushed downward by the lower surface 222 of the body, and only at least a part of it is exposed outside the water outlet pipe 200, and the lip seal 34 is also located outside the water outlet pipe 200. This is the state shown in the middle part of Figure 22. The user only needs to gently pull the bubbler 3 out of the water outlet pipe 200.

In this embodiment, the process of installing the connection assembly 10 to the water outlet pipe 200 is exactly the same as the installation process of the first embodiment, and will not be repeated here.

From the above introduction, it can be known that the present embodiment provides a ballpoint pen bouncing mechanism, so that the bubbler 3 can be switched when being grasped and released through pressing and releasing actions, so that the bubbler 3 can be removed from the water outlet pipe by pressing the bubbler from above and releasing it. Therefore, the bubbler 3 can be completely hidden in the water outlet pipe 200 when the connection is completed to avoid the formation of a seam between the bubbler 3 and the water outlet pipe 200.

Of course, there are many variations of similar ballpoint pen bouncing mechanisms, which are not listed here one by one. The greatest contribution of this embodiment is that the extension and retraction of the elastic claw 223 relative to the seat body 13 is combined with the ballpoint pen bouncing mechanism structure, which solves the problem of the bubbler 3 being built into the water outlet pipe 200, and can also be easily installed and removed.

The above specification and description of the embodiments are used to explain the protection scope of the present application, but do not constitute a limitation on the protection scope of the present application.
