Detailed Description

Before the present invention is described in detail, it should be noted that in the following description, like elements are represented by like reference numerals.

Referring to fig. 1 to 3, the first embodiment of the vented mirror apparatus of the present invention includes a hand-held module 10 and a rotating mirror module 20.

The handheld module 10 includes a carrier 1 and a handle 2 connected to the carrier 1. The carrier 1 has a peripheral wall 11, an installation wall 12 connected to the inner periphery of the peripheral wall 11, and a bottom cover 13, and the peripheral wall 11 and the installation wall 12 together define a first chamber 14 and a second chamber 15 respectively located at two sides of the installation wall 12, and a plurality of air outlet slits 16 distributed at intervals along the peripheral side of the first chamber 14 and communicated with the second chamber 15. The bottom cover 13 is connected to the peripheral wall 11 to close the second chamber 15, in this embodiment, the bottom cover 13 and the peripheral wall 11 are provided with matching threads, so that the bottom cover 13 can be detachably connected to the peripheral wall 11. The handle 2 is connected to the peripheral wall 11 and forms an air inlet channel 21 communicating with the second chamber 15 together with the peripheral wall 11. The peripheral wall 11 has a flow guide portion 111 to define an outlet 211 of the air inlet passage 21, such that the outlet 211 is inclined with respect to a radial direction of the peripheral wall 11.

Referring to fig. 4, the rotating mirror module 20 is disposed on the mounting wall 12 and includes a rotating mirror 3 and a driving element 4. The rotating mirror 3 has a mirror body 31 rotatably received in the first accommodating chamber 14, and a mirror shaft 32 connected to the mirror body 31 and passing through the mounting wall 12, wherein the mirror shaft 32 is sleeved with a bearing 5. The driving element 4 has a connecting shaft 41 connected to the mirror shaft 32 and a plurality of paddles 42 connected to the connecting shaft 41, and the paddles 42 are driven by the airflow flowing out from the air inlet channel 21 to drive the rotating mirror 3 to rotate around the mirror shaft 32. In this embodiment, the connecting shaft 41 has a truncated cone-shaped engaging portion 411, the mirror shaft 32 has a concave portion 321 with a shape matching with the engaging portion 411 to accommodate the engaging portion 411, and the connecting shaft 41 and the mirror shaft 32 are screwed and connected by a locking member 6 along the axis of the connecting shaft 41 and the mirror shaft 32. Through the combination of the truncated cone shape of the joint 411 and the complementary shape of the concave portion 321 of the mirror shaft 32, the axes of the connecting shaft 41 and the mirror shaft 32 are consistent on a short connecting surface, and the connecting shaft and the mirror shaft 32 are not easy to skew, so as to ensure that the mirror body 31 and the paddle 42 are arranged in parallel in the rotating direction, and the connecting structure of the connecting shaft 41 and the mirror shaft 32 is simpler to reduce the volume, so that the space occupied by the connecting structure can be saved, the length of the paddle 42 can be increased in a limited space, and the rotating efficiency can be improved.

Referring to fig. 1 and 5, the handle 2 has a tube 22 and a switch 23 disposed on the tube 22, and the switch 23 can be operated to switch between an open state (shown in fig. 1) for opening the air inlet passage 21 and a closed state (shown in fig. 5) for blocking the air inlet passage 21. In this embodiment, the switch 23 is a rotary ball valve and has a ball valve passage 231. As shown in fig. 1, when the ball valve passage 231 communicates with the air inlet passage 21 in the pipe body 22, the air inlet passage 21 is opened, so that the air can flow in the air inlet passage 21. As shown in fig. 5, when the ball valve passage 231 is not communicated with the air inlet passage 21 in the pipe body 22, the air inlet passage 21 is blocked, and the gas cannot pass through.

Referring to fig. 1 to 3, the end of the handle 2 may be connected to an air supply device (not shown), such as an air pump, so that compressed air is input into the second chamber 15 through the air inlet channel 21, and when the air is guided by the air guiding portion 111 to flow out from the outlet 211, the direction of the outlet 211 is inclined relative to the radial direction of the peripheral wall 11, so as to increase the force application area on the surface of the paddle 42, thereby improving the rotation efficiency of the paddle 42. The cross-sectional shape of the paddle 42 can be adjusted, for example, the cross-sectional shape can also be S-shaped, so as to achieve better rotation effect in cooperation with the airflow.

The gas entering the second chamber 15 flows out of the second chamber 15 through the gas outlet gap 16. The outlet position of the outlet gap 16 is higher than the mirror 311 of the mirror 31, and the angle between the outlet direction D of the outlet gap 16 and the mirror 311 is preferably not more than 90 degrees. In the present embodiment, the gas outlet direction D of the gas outlet gap 16 is oriented toward the central axis a of the mirror 31 and is substantially parallel to the mirror surface 311 of the mirror 31, that is, the angle between the gas outlet direction D of the gas outlet gap 16 and the mirror surface 311 is about 0 degree, so that the gas curtain 7 can be formed on the mirror surface 311 of the mirror 31. The air curtain 7 can not only remove the fog, but also protect the mirror surface 311 of the mirror body 31, and can avoid the human tissue in the oral cavity of the patient from being damaged when the mirror body 31 rotates. Because the paddle 42 is pushed by the compressed air, and the temperature of the compressed air is lower than the room temperature, so that the temperature of the mirror body 31 of the rotating mirror 3 is lower than the room temperature under the influence of the compressed air, and the temperature of the mirror body 31 can be reduced when the rotating mirror 3 rotates, when the rotating mirror body 31 is positioned in the oral cavity, the mirror surface 311 of the mirror body 31 is easily fogged under the action of a warmer and humid environment in the oral cavity, and therefore, the hot air in the oral cavity can be isolated by forming the air curtain 7 on the mirror surface 311 of the mirror body 31, and the effect of completely demisting is achieved. That is, the rotating mirror 3 can not only prevent the sprayed water droplets from adhering by rotating, but also prevent the mirror surface 311 from fogging due to temperature difference by the air curtain 7, thereby achieving the effect of completely defogging. Furthermore, during the treatment process of the dentist, the splashed water drops may have dust or debris, and the air curtain 7 can prevent the water drops with the dust or debris from impacting the mirror surface 311 of the mirror body 31, so that the mirror surface 311 of the mirror body 31 can be protected from damage. In addition, when the rotating mirror 3 is in the oral cavity, the air curtain 7 can prevent the mirror body 31 from directly contacting the human tissue in the oral cavity, thereby achieving the effect of protecting the human tissue.

The switch 23 can be controlled by a user to control whether the gas enters the second chamber 15, so as to control whether the rotating mirror 3 rotates. However, in alternative embodiments, it may be implemented without the switch 23.

Referring to fig. 6, a second embodiment of the exit mirror device of the present invention is substantially the same as the first embodiment, except that in the second embodiment, the angle between the exit direction D of the exit slit 16 and the mirror surface 311 of the mirror body 31 is between 30 and 90 degrees, so that the gas flowing out of the exit slit 16 can be collected toward the central axis a. Thereby, when the mirror surface 311 of the mirror body 31 is at a distance from the teeth 8, the concentrated gas can help to blow away excess water bloom or debris from the teeth 8 and its surrounding area, so that the teeth 8 can be more clearly viewed.

The angles of the air outlet direction D of the air outlet slits 16 relative to the mirror 311 can have different functions, and can be adjusted according to the actual requirement, which is not limited to the foregoing embodiment, and in the modified embodiment, different air outlet slits 16 of the same susceptor 1 can also be designed to have different air outlet directions D. In addition to the different functions of the different angles of the air outlet direction D of the air outlet gap 16 relative to the mirror 311, the volume of the handle 2 can be reduced because the air entering the second chamber 15 can be exhausted from the air outlet gap 16 without providing an air outlet channel on the handle 2.

Referring to fig. 7 and 8, a third embodiment of the air outlet type mouth mirror device of the present invention is substantially the same as the first embodiment, except that in the third embodiment, the switch 23 has a force-receiving portion 232 capable of sliding on the tube 22 and a blocking portion 233 linked by the force-receiving portion 232. By pushing or pulling the force-receiving portion 232, the depth of the blocking portion 233 extending into the tube 22 can be controlled. As shown in fig. 7, when the blocking portion 233 does not fully extend into the tube 22 when the switch 23 is in the open state, the air inlet passage 21 is not blocked and opens the air inlet passage. As shown in fig. 8, when the switch 23 is in the closed state, the blocking portion 233 completely extends into the tube 22 to block the air inlet passage 21. Therefore, pushing and pulling the force-receiving portion 232 can control the switch 23 to be in the open state or the closed state.

Referring to fig. 9 and 10, a fourth embodiment of the air outlet type mouth mirror device of the present invention is substantially the same as the first embodiment, except that in the fourth embodiment, the tube 22 of the handle 2 has a fixed section 221 connected to the carrier 1 and a rotating section 222 sleeved with the fixed section 221, and the switch 23 is composed of two semicircular stoppers 234 respectively disposed at the connection positions of the fixed section 221 and the rotating section 222. As shown in fig. 9, when the switch 23 is in the open state, the position of the stopper 234 on the rotating section 222 overlaps with the position of the stopper 234 on the fixed section 221, so that the space of the rotating section 222 is communicated with the space of the fixed section 221, i.e. the air inlet passage 21 is opened. As shown in fig. 10, when the switch 23 is in the closed state, the position of the stopper 234 on the rotating section 222 is dislocated from the position of the stopper 234 on the fixed section 221, so that the space of the rotating section 222 is not communicated with the space of the fixed section 221, i.e. the air inlet passage 21 is blocked. Therefore, rotating the rotating section 222 can control the switch 23 to be in the open state or the closed state.

In summary, the airflow introduced into the second chamber 15 pushes the driving element 4 to rotate the rotating mirror 3, and the airflow can be discharged from the air outlet slits 16 distributed at intervals along the circumferential side of the first chamber 14, so that not only the water drops are not attached to the mirror surface 311, but also various additional functions can be added by the gas discharged from the air outlet slits 16, thereby achieving safety and improving defogging effect.

The above description is only an example of the present invention, and the scope of the present invention should not be limited thereby, and the invention is still within the scope of the present invention by simple equivalent changes and modifications made according to the claims and the contents of the specification.
