Description

Technical Field

[0001] This utility model relates to the field of bathroom products technology, and in particular to a faucet switching valve. Background Technology

[0002] In recent years, basin faucets with beauty functions have become popular. These faucets typically add a beauty device to the main aerator, with the water flow switching between the main aerator and the beauty device via a switch. To facilitate operation and precisely control the water flow to prevent splashing, the switch usually uses a push-button design. However, because the flow rate of the beauty device differs significantly from that of the main aerator, and the beauty device also has a shut-off mechanism, conventional push-button switches cannot achieve effective switching due to back pressure, affecting the user experience. Utility Model Content

[0003] Therefore, this utility model proposes a push-button switching valve that is unaffected by water pressure.

[0004] To address the aforementioned technical problems, this utility model provides the following technical solution:

[0005] A faucet switching valve includes: a switching valve body and a control component and a drive component mounted on the switching valve body. The switching valve body includes an inlet and a first outlet and a second outlet. The control component is respectively installed at the first outlet and the second outlet. The drive component operably drives the control component to open or close the first outlet and the second outlet. The control component includes a diaphragm seat and a valve core drive rod. The diaphragm seat is slidably mounted on the first outlet / second outlet and has a sliding hole. One end of the valve core drive rod is slidably connected to the sliding hole of the diaphragm seat, and the other end is connected to the drive component. The drive component can switch between a first working position and a second working position. When the drive component is in the first working position, the control component at the first outlet is in a conducting state, and the control component at the second outlet is in a closed state. When the drive component is in the second working position, the control component at the second outlet is in a conducting state, and the control component at the first outlet is in a closed state.

[0006] Specifically, in one optional embodiment, the control component further includes a first elastic element located between the switching valve body and the diaphragm seat. The first elastic element acts on the diaphragm seat and keeps the first outlet or the second outlet closed when not subjected to external force.

[0007] Specifically, in one optional embodiment, the sliding hole is provided in the central region of the diaphragm seat, and the cross-sectional area of ​​the valve core drive rod is 1 / 10 to 1 / 5 of the cross-sectional area of ​​the water outlet (first water outlet or second water outlet).

[0008] Specifically, in one optional embodiment, the first water outlet and the second water outlet extend in the same direction, and the control components on the first water outlet and the second water outlet move in opposite directions under the action of the drive component.

[0009] Specifically, in one optional embodiment, the diaphragm seat includes a rigid support body and a flexible sealing membrane covering the rigid support body, and the valve core drive rod is slidably and sealingly connected to the diaphragm seat through the flexible sealing membrane.

[0010] Specifically, in one optional embodiment, the two diaphragm seats located at the first outlet and the second outlet are integrally formed, the two diaphragm seats are connected by a flexible sealing connection between them, and the two diaphragm seats are constructed as deformable structures.

[0011] Specifically, in one optional embodiment, the drive assembly includes a drive button slidably connected to the switching valve body and a transmission slider assembly located between the drive button and the valve core drive rod.

[0012] Specifically, in one optional embodiment, the sliding direction of the drive button is perpendicular to the sliding direction of the valve core drive rod, the transmission slider group includes a first slider, a second slider and two third sliders, and the transmission slider groups are respectively engaged by inclined surfaces; the first slider and the drive button are engaged by inclined surfaces, and the two valve core drive rods are respectively fixedly connected to the two third sliders.

[0013] Specifically, in one optional embodiment, the drive assembly further includes a second elastic element located between the first slider and the switching valve body. The second elastic element acts on the first slider and keeps it in the first working position when it is not subjected to external force.

[0014] Specifically, in one optional embodiment, the drive assembly further includes a third elastic element located between the second slider and the switching valve body, the third elastic element acting on the second slider and keeping it in the first working position when not subjected to external force.

[0015] The technical solution of this utility model has the following technical advantages over the prior art:

[0016] The faucet switching valve provided by this utility model adopts a diaphragm seat and a valve core drive rod to form a control component. The drive component cooperates with the valve core drive rod. Since the cross-sectional area of ​​the valve core drive rod is relatively small compared to the diaphragm seat and the outlet, the drive component only needs to apply a small driving force to realize the sliding of the diaphragm seat. This avoids the problem that when the back pressure of the outlet is large, the cross-section of the component that closes the outlet is large, which would require the drive component to apply a large force to realize the switching of the two outlet channels. This greatly improves the convenience and reliability of the faucet switching valve and provides a better user experience. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0028] like Figures 1-6 The diagram shows one specific embodiment of this faucet switching valve. This switching valve can be used with faucets having two outlets, especially faucets with a large difference in flow rate between the two outlets, such as basin faucets with a beauty function.

[0029] like Figure 1 , Figure 2 As shown, the faucet switching valve comprises a switching valve body 10 and a control component 20 and a drive component 30 mounted on the switching valve body 10. The switching valve body 10 has an inlet 11, a first outlet 12, and a second outlet 13. The control component 20 is respectively installed at the first outlet 12 and the second outlet 13. The drive component 30 can control the operation of the control component 20, thereby realizing the opening and closing of the first outlet 12 and the second outlet 13. This structural design can meet different water usage needs and facilitate users to switch water flow channels.

[0030] Among them, such as Figure 4 , Figure 6 As shown, the control component 20 includes a diaphragm seat 21 and a valve core drive rod 22. The diaphragm seat 21 is slidably mounted on the first outlet 12 or the second outlet 13. One end of the valve core drive rod 22 is slidably connected to the sliding hole 211 of the diaphragm seat 21, and the other end is connected to the drive component 30. The drive component 30 can switch between a first working position and a second working position, such as... Figure 4As shown, when the drive component 30 is in the first working position, the control component 20 at the first outlet 12 is in the on state, and the control component 20 at the second outlet 13 is in the off state; Figure 6 As shown, when the drive component 30 is in the second working position, the control component 20 at the second outlet 13 is in the conducting state, and the control component 20 at the first outlet 12 is in the closed state.

[0031] In the aforementioned faucet switching valve, a control assembly 20 is formed by a diaphragm seat 21 and a valve core drive rod 22. The drive assembly 30 cooperates with the valve core drive rod 22. Since the cross-sectional area of ​​the valve core drive rod 22 is relatively small compared to the diaphragm seat 21 and the water outlets (first water outlet 12 and second water outlet 13), the drive assembly 30 only needs to apply a small driving force to achieve the sliding of the diaphragm seat 21. This avoids the problem that when the back pressure at the water outlet is large, the cross-section of the component sealing the water outlet is large, which would require the drive assembly 30 to apply a large force to achieve the switching of the two water outlet channels. This greatly improves the ease of use and reliability of the faucet switching valve, resulting in a better user experience.

[0032] Specifically, in one alternative implementation, such as Figure 4 , Figure 6 As shown, the diaphragm seat 21 has a sliding hole 211 in its central region, and the valve core drive rod 22 is slidably connected to the sliding hole 211, which can make the diaphragm seat 21 bear force evenly. The valve core drive rod 22 has a necked section 221 along its axial direction. When the valve core drive rod 22 moves axially, there is a gap between the necked section 221 and the sliding hole 211 when they cooperate, which can release the back pressure in the valve cavity, so that the diaphragm seat 21 can move under the action of the inlet water pressure, so that the inlet 11 can communicate with the outlet (first outlet 12 or second outlet 13).

[0033] Specifically, in one optional embodiment, the cross-sectional area of ​​the valve core drive rod 22 is 1 / 10 to 1 / 5 of the cross-sectional area of ​​the water outlet (first water outlet 12 or second water outlet 13). This proportional design makes the diameter of the valve core drive rod 22 relatively small, so as to achieve water outlet switching with a smaller driving force.

[0034] Specifically, such as Figure 4 , Figure 6As shown, the control component 20 also includes a first elastic element 23 located between the switching valve body 10 and the diaphragm seat 21. When no external force is applied, the first elastic element 23 applies a force to the diaphragm seat 21, keeping the diaphragm seat 21 closed at the first outlet 12 or the second outlet 13. When it is necessary to open the outlet (first outlet 12 or second outlet 13), the drive component 30 overcomes the elastic force of the first elastic element 23 through the valve core drive rod 22, pushing the diaphragm seat 21 to slide, thereby realizing the opening of the outlet (first outlet 12 or second outlet 13).

[0035] In one alternative implementation, such as Figure 2 As shown, the diaphragm seat 21 consists of a rigid support body 212 and a flexible sealing membrane 213 covering it. The rigid support body 212 ensures the structural strength of the diaphragm seat 21, while the flexible sealing membrane 213 provides a good sealing effect. The valve core drive rod 22 achieves a sliding sealing connection with the diaphragm seat 21 through the flexible sealing membrane 213, which ensures the smooth sliding of the valve core drive rod 22 and prevents water leakage.

[0036] Furthermore, in an alternative implementation, such as Figure 2 , Figure 4 and Figure 6 As shown, the two diaphragm seats 21 located at the first outlet 12 and the second outlet 13 are integrally formed and connected by a flexible sealing connection 214 between them to reduce the manufacturing cost of the diaphragm seats 21. Furthermore, the two diaphragm seats 21 are constructed as deformable structures. This design allows the two diaphragm seats 21 to achieve on / off switching with the outlets (first outlet 12 and second outlet 13) through their own deformation under the action of the drive assembly 30. The two diaphragm seats 21 do not affect each other, further improving the operating performance of the switching valve.

[0037] Specifically, in one optional embodiment, the drive assembly 30 includes a drive button 31 slidably connected to the switching valve body 10 and a transmission slider group 32 located between the drive button 31 and the valve core drive rod 22. The drive button 31 is a user-operated component, and by pushing the drive button 31, the drive assembly 30 can be switched between a first working position and a second working position.

[0038] Specifically, the transmission slider assembly 32 consists of sliders that engage with each other via inclined planes; in one optional embodiment, such as Figure 1 , Figure 4 , Figure 6As shown, the transmission slider assembly 32 consists of a first slider 321, a second slider 322, and two third sliders 323, with each slider connected by an inclined plane. The first slider 321 is also connected to the drive button 31 by an inclined plane, and the two valve core drive rods 22 are fixedly connected to the two third sliders 323 respectively. This inclined plane design converts the horizontal sliding of the drive button 31 into the sliding of each slider, ultimately driving the valve core drive rods 22 to slide vertically, thereby driving the control component 20.

[0039] More specifically, the first slider 321 engages with the inclined surface of the drive button 31 to convert the horizontal sliding of the drive button 31 into the vertical sliding of the first slider 321; the inclined surface of the first slider 321 engages with the inclined surface of the second slider 322 to convert the vertical sliding of the first slider 321 into the horizontal sliding of the second slider 322. The two sides of the second slider 322 engage with the inclined surfaces of two third sliders 323 respectively, and the extension directions of the two inclined surfaces intersect, so that when the second slider 322 moves horizontally in the first direction, the third slider 323 on the side of the first outlet 12 moves downward and the third slider 323 on the side of the second outlet 13 moves upward; while when the second slider 322 moves horizontally in the second direction (the second direction is opposite to the first direction), the third slider 323 on the side of the first outlet 12 moves upward and the third slider 323 on the side of the second outlet 13 moves downward; thereby realizing the switching of the first outlet 12 and the second outlet 13.

[0040] Specifically, in one alternative implementation, such as Figures 3-6 As shown, the drive assembly 30 further includes a second elastic element 33 and a third elastic element 34. The second elastic element 33 is located between the first slider 321 and the switching valve body 10, and the third elastic element 34 is located between the second slider 322 and the switching valve body 10. When no external force is applied, the second elastic element 33 acts on the first slider 321, and the third elastic element 34 acts on the second slider 322, keeping them in the first working position. When the drive button 31 is pushed, the drive assembly 30 overcomes the elastic force of the second elastic element 33 and the third elastic element 34, switching to the second working position; after the external force on the drive button 31 is removed, the drive assembly 30 automatically returns to the first working position under the action of the second elastic element 33 and the third elastic element 34.

[0041] The working process of the above-mentioned faucet switching valve is as follows:

[0042] like Figure 3 , Figure 4As shown, when the drive assembly 30 is in the first working position, i.e., the drive button 31 is not pushed, the first slider 321 and the second slider 322 remain in their initial positions under the action of the second elastic element 33 and the third elastic element 34. At this time, the valve core drive rod 22 corresponding to the first outlet 12 overcomes the elastic force of the first elastic element 23 under the action of the transmission slider group 32, pushes the diaphragm seat 21 to slide, and opens the first outlet 12; while the diaphragm seat 21 at the second outlet 13 remains closed under the action of the first elastic element 23, and water flows in from the inlet 11 and flows out through the first outlet 12.

[0043] When the user pushes the drive button 31, such as Figure 5 , Figure 6 As shown, sliding the drive button 31 drives the first slider 321 and the second slider 322 to move via the inclined plane, thereby actuating the transmission slider assembly 32. The valve core drive rod 22 corresponding to the second outlet 13 pushes the diaphragm seat 21 to slide, opening the second outlet 13; simultaneously, the diaphragm seat 21 at the first outlet 12 closes the first outlet 12 under the action of the first elastic element 23, and water flows in from the inlet 11 and out through the second outlet 13. When the external force on the drive button 31 is removed, the drive assembly 30 returns to the first working position under the action of the second elastic element 33 and the third elastic element 34.

[0044] The faucet switching valve of this utility model effectively solves the problem that the drive button 31 cannot be pressed due to the large back pressure at the outlet by setting a control component 20 with a valve core drive rod 22 of a smaller diameter. It realizes the switching operation of the outlet (first outlet 12 and second outlet 13) with a smaller driving force, and has good performance and reliability.

[0045] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
