Description

Technical Field

[0001] This utility model relates to the field of valve equipment, and in particular to a reversing faucet valve. Background Technology

[0002] A directional valve is used in valves with multiple water outlet channels. By rotating the valve core, different water outlet and inlet channels are connected, thereby controlling the flow, shut-off, reversal, and flow rate of the liquid. The direction of the valve is controlled by the relative movement between the valve core and the valve body. There are two types: rotary valve and slide valve.

[0003] Rotary valve-type directional faucet valves are commonly used in daily households. Their structure involves opening different through holes in the valve core, with sealing plates fitted around the valve core's periphery. When the valve core is rotated, different water outlet and inlet channels are connected through the through holes. However, with long-term rotation, the sealing plates of this type of valve core are easily worn, leading to leaks. This necessitates frequent replacement of the sealing plates, resulting in a short service life and impacting the user experience. Summary of the Invention

[0004] In view of this, it is necessary to provide a reversing valve with a simple structure, good sealing performance, and long service life.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a reversing faucet valve, comprising: The valve body has an inlet channel and at least one outlet channel, and the inlets of the outlet channels are all connected to the inlet channel; A valve core is provided at the inlet of each of the water outlet channels. An elastic element is connected inside the water outlet channel. The elastic element acts on the valve core and always maintains the tendency to push the valve core out and away from the water outlet channel. There is a water passage gap between the peripheral sidewall of the valve core and the inner sidewall of the water outlet channel. The top of the valve core is exposed outside the water outlet channel. A sealing element for sealing the inlet of the water outlet channel is connected to the top of the peripheral sidewall of the valve core. A valve button is rotatably connected to the valve body. The valve button, located within the valve body, has a driving surface that contacts the top of the valve core. The driving surface is curved. When the valve button rotates, the driving surface pushes the valve core to reciprocate along the axial direction of its outlet channel. When the valve core moves, its outlet channel has the following two modes: In the water outlet mode, the valve core, along with the seal, is moved away from the inlet of the water outlet channel; In the closed mode, the valve core, along with the seal, seals the inlet of the water outlet channel.

[0006] Furthermore, the valve knob located within the valve body has a bottom surface with an annular groove on the bottom surface. The bottom surface of the annular groove constitutes the driving surface, and the top of the valve core is slidably connected within the annular groove.

[0007] Furthermore, the elastic element is a spring.

[0008] Furthermore, the valve body has a chamber, and both the water inlet channel and the water outlet channel are connected to the chamber.

[0009] Furthermore, the valve knob is rotatably connected to the chamber.

[0010] Furthermore, the valve core includes a crossbar and a slide connected to the top of the crossbar.

[0011] Furthermore, the sealing element is a first sealing ring fitted onto the peripheral sidewall of the slide head, and the slide head is slidably connected to the annular groove.

[0012] Furthermore, the peripheral wall of the valve knob has a second sealing ring that rotates and seals against the inner wall of the cavity.

[0013] Furthermore, a handle for driving the valve button to rotate is fixedly connected to the valve button.

[0014] Furthermore, a connector is screwed onto the valve body to confine the valve knob within the chamber.

[0015] Compared with the prior art, the present invention has the following advantages: the faucet valve drives the valve core to reciprocate within the water outlet channel through a curved driving surface, thereby controlling the opening and closing of the water outlet channel, avoiding wear of the sealing components, with a simple structure, good sealing performance, and long service life.

Detailed Implementation

[0026] To further illustrate the technical means and effects of this utility model in achieving its intended purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0027] like Figure 1-5 As shown, a reversing valve includes: a valve body 1, a valve core 2, and a valve knob 3. This embodiment uses a one-inlet, two-outlet valve as an example for illustration.

[0028] like Figure 6 As shown, the valve body 1 has a chamber 11, which is connected to an inlet channel 12, a first outlet channel 13, and a second outlet channel 14.

[0029] Each water outlet channel is equipped with a valve core 2 at its inlet. An elastic element is connected inside the water outlet channel. In this embodiment, the elastic element is a spring 21. The spring 21 acts on the bottom of the valve core 2 and always maintains the tendency to push the valve core 2 out and away from the water outlet channel. There is a water passage gap between the peripheral side wall of the valve core 2 and the inner side wall of the water outlet channel. The top of the valve core 2 is exposed outside the water outlet channel. A sealing element for sealing the inlet of the water outlet channel is connected to the top of the peripheral side wall of the valve core 2.

[0030] In this embodiment, as Figure 8 As shown, the valve core 2 includes a cross rod 21 and a slider 22 connected to the top of the cross rod. The outer side of the cross rod 21 contacts the inner wall of the water outlet channel, which can prevent the valve core 2 from shaking during movement. At the same time, the structure of the cross rod 21 itself ensures that there is a water passage gap between it and the inner wall of the water outlet channel. The sealing element is a first sealing ring 24 sleeved on the peripheral side wall of the slider 22.

[0031] like Figure 7 As shown, the valve button 3 is rotatably connected to the chamber 11. The valve button 3 located in the chamber 11 has a bottom surface with an annular groove 31. The bottom surface of the annular groove 31 forms a driving surface 32. The driving surface 32 is in contact with the top of the valve core 2 (i.e., the top of the slider). The driving surface 32 is curved. When the valve button 3 rotates, the driving surface 32 pushes the valve core 2 to reciprocate along the axial direction of the water outlet channel where it is located.

[0032] The slider 22 is slidably connected to the annular groove 31. The presence of the annular groove 31 can prevent the slider 22 from disengaging from the valve knob 3, ensuring that the valve core 2 will not disengage from the driving surface when the valve knob 3 is rotated.

[0033] That is, when valve button 3 rotates, valve core 2 moves axially back and forth because the driving surface 32 is curved. When valve core 2 moves, the water outlet channel it occupies has the following two modes: In the water outlet mode, valve core 2, along with the first sealing ring 24, is moved away from the inlet of the water outlet channel; In the closed mode, valve core 2, along with the first sealing ring 24, seals the inlet of the water outlet channel.

[0034] In this embodiment, the design of the curvature of the drive surface 32 needs to meet the movement stroke of the valve core 2, so as to ensure that the valve core 2 can open and close the water outlet channel to the maximum extent.

[0035] In this embodiment, the peripheral sidewall of the valve button 3 has a second sealing ring 33 that rotates and seals with the inner sidewall of the cavity.

[0036] In this embodiment, a handle 5 is fixedly connected to the valve button 3 to drive the valve button to rotate.

[0037] In this embodiment, a connector 4 is screwed onto the valve body 1 to confine the valve button 3 within the cavity.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
