Integrated water-saving aerator

technical field

The invention relates to a sanitary built-in component, in particular to an integrated bubbler with throttling function.

Background technique

As a hygienic component, the bubbler has been widely used in bathrooms and cleaning facilities. Its function is to treat the water flow in the branch circuit, make the water body dispersed into particles, and then suck in air, and finally become a large number of air bubbles. Rinse with water. These parts have various styles and are installed in terminal equipment such as faucets and showers. At the same time, in order to achieve more functions, these parts can be modularized and combined with other parts to make them have functions other than foaming. Other features, such as water flow regulation, automatic water saving and so on. The modular setting can bring abundant functions, but it will inevitably increase the cost of materials and processes, and at the same time, there is a certain waste in the use functions of each component. Especially when the bubbler needs to have a throttling function, adding a throttling component to the front end of the bubbler often requires many parts and complicated processes.

Detailed ways

As shown in Fig. 1 to Fig. 7, a schematic diagram of an embodiment of the present invention.

As shown in Figures 1 to 3, an integrated water-saving bubbler includes components such as a filter element 10, an elastic water blocking element 20, a diverter 30, a fixing ring 40, a metal mesh 50 and a body 60, wherein the body 60, the body 60 has a sudden change cavity 63; there is an installation port 65 and a water outlet 62 at both ends of the sudden change cavity 63, and its side has an air suction port 61 communicating with the external space; the body 60 is a bowl-shaped part located at The end of the entire bubbler waterway.

The installation port 65 of the body 60 fits and fixes the fixing ring 40. The other end of the fixing ring 40 fits and fixes the filter component 10; therefore, the body 60, the fixing ring 40 and the filter component 10 constitute a container, which accommodates the diverter 30 . The splitter 30 is fixed in the fixed ring 40 and has a splitter surface 36. The splitter surface 36 is between the filter member 10 and the water outlet 62 in the waterway sequence. The elastic water blocking element 20 ; the diversion port 35 communicates with the sudden change cavity 63 through the diversion channel 39 .

Combining Figures 3 to 6, Figures 3 and 5 are cross-sectional views of the two states, and Figures 4 and 6 are cross-sectional views of the cross sections aa and bb, respectively. What Fig. 3 and Fig. 4 show is low water pressure or static state, Fig. 5 and Fig. 6 are the working state with obvious water pressure.

In Fig. 3, an important feature is that the elastic water blocking member 20 is not deformed, therefore, as shown in Fig. 4, the effective cross-sectional area of the diversion port 35 on the diverter 30 is almost not reduced, and the diversion channel 39 is in the maximum flow state , if the state is low water pressure, it means that the pressure of the water entering the filter element 10 is very small, and the flow rate per unit time is also very small, and the water passes through the shunt channel 39 and the contraction chamber 42 almost without hindrance, and suction occurs in the sudden change chamber 63 Mixed, collided, so that it becomes an output water flow rich in a large number of bubbles. After the metal mesh 50 and the water outlet hole 62 are broken up, the final sparkling water will flow out.

In FIG. 5, the elastic water blocking member 20 has been deformed by the action of the water pressure. Therefore, as shown in FIG. The effective cross-sectional area of the diversion port 35 is reduced, so that the flow and pressure of the diversion channel 39 are limited, and the flow and pressure of the finally generated bubble water are also limited, and the flow direction of the obviously throttled bubble water is shown by the arrow in FIG. 5 .

It can be seen that the elastic water blocking element 20 is placed at the front end of the diverter 30, directly facing the water flow from the filter element 10, and has good sensitivity and adaptability to the water pressure. At the same time, the assembly is very simple, and the elastic water blocking element 20 can be quickly assembled and disassembled on the The frustum-shaped boss 31 forms an integral body with the flow divider 30 .

The diversion ports 35 are annularly distributed on the diversion surface 36, and are distributed on the outer periphery of the elastic water blocking member 20. The elastic water blocking member 20 expands and deforms in a ring shape, and the area change caused by the deformation is obvious, so that the effect of shielding the diversion ports 35 is good. The sensitivity is high and stable. There is also a protrusion 32 at the diversion port 35 that limits the expansion degree of the elastic water blocking member 20, and the protrusion 32 can control the extent to which the elastic water blocking member 20 covers the diversion port 35, so that the throttling effect can be controlled more accurately. Obtain throttling sparkling water with high stability.

In this solution, as shown in FIG. 1 , the splitter 30 has a splitter section 34 at the end facing the water outlet 62, and the splitter channel 39 has an opening on the side of the splitter section; the side of the splitter section 34 and the inner wall 41 of the fixed ring 40 form Annular constriction cavity 42 ; the cross section of the constriction cavity 42 gradually shrinks toward the water outlet 62 along its axial direction, and expands again when reaching the sudden change cavity 63 . In this way, a good inhalation effect in the sudden change chamber 63 can be finally obtained. Particularly, as shown in Figure 7, the fixed ring 40 has an inner flange 44 at one end fixed to the body 60, the top surface 47 of the inner flange is one side of the abrupt cavity 63, and the side surface of the inner flange 44 is The inner wall 41 of the constriction chamber 42 . This form makes the function of the contraction cavity 42 formed by the inclination of the inner wall 41 and is directly molded inside the fixing ring 40 , so that the fixing ring 40 has a higher utilization rate.

In this solution, there is a metal mesh 50 before the water outlet, which can process the water flow that has been mixed with air to make it more stable; the water outlet 62 is rectangular, and the array is distributed on the bottom surface of the body, which can further make air bubbles Under the condition that the water flow does not affect its flow rate, the suction effect can be obtained after flowing out, so as to improve its cleaning performance.

In summary, it can be seen that this solution realizes automatic throttling and foaming generation, and has the characteristics of an integrated structure. It consumes few parts, and only needs filter parts 10, elastic water blocking parts 20, restrictors 30, and fixing rings 40 and the body 60, a total of 5 parts can realize the basic functions, and the elastic water blocking member 20 can be assembled with the restrictor 30, which simplifies the complexity of the entire throttling bubbler and optimizes the cost of materials and assembly process. brought obvious results. At the same time, the number of parts of the bubbler is small, which also guarantees the stability and reliability of the foaming effect.

The above is only a preferred embodiment of the present invention, so the scope of implementation of the present invention cannot be limited accordingly, that is, equivalent changes and modifications made according to the patent scope of the present invention and the content of the specification should still be covered by the present invention within range.
