Description

Technical Field

[0001] This utility model belongs to the field of shower faucet technology, specifically referring to a water distribution valve body and faucet with shower dual functions. Background Technology

[0002] Currently, shower faucets have become an indispensable facility in modern living spaces. To meet diverse bathing needs, they typically require a dual-function water flow system, combining both showerhead and bathtub water output. The key technology for such faucets lies in water path switching, while simultaneously ensuring reliability and minimizing manufacturing costs.

[0003] The most common way to switch water circuits in dual-function faucets on the market is to install a lever or button-type switching valve on either of the water outlets. When it is necessary to switch water circuits, the switching valve is used to close the water circuit and open the other water circuit. This method usually requires independent installation, resulting in a large overall size of the faucet. The additional valve body increases material consumption and assembly costs. Utility Model Content

[0004] The purpose of this utility model is to provide a water distribution valve body and faucet with two functions of showering, which overcomes the above-mentioned defects, achieves stable water circuit switching, and has a compact structure that saves installation space and reduces manufacturing costs.

[0005] The purpose of this utility model is achieved as follows: A water distribution valve body with shower function includes a columnar water distribution core. The top of the water distribution core has a first water inlet and a second water inlet formed by a first flow channel and a second flow channel, respectively. The upper end of the water distribution core has a first water outlet. A switch valve body is provided on the top of the water distribution core to connect the first water inlet and the first water outlet or the second water inlet and the second water outlet. The water distribution core has an installation through hole extending in the front-back direction. The first water outlet is connected to the upper wall of the installation through hole. A shower head connector is sealed to the rear end of the installation through hole. The bottom of the water distribution core has a second water outlet connected to the lower wall of the installation through hole. The first water outlet and the second water outlet are not vertically aligned. A screw is rotatably connected to the front end of the installation through hole. The rear end of the screw extends into the installation through hole and is screwed with a rotating head. A sealing plug is snapped into the rotating head. A water guide hole with vertical connection is provided on the rotating head.

[0006] The present invention is further configured such that the rotating head includes a nut end screwed to the end of the screw, the side wall of the nut end is provided with the water guiding hole, the mounting hole includes a front section and a rear section, the cross section of the front section of the mounting hole is a regular hexagon adapted to the nut end, and the second water outlet is provided on the lower side wall of the front section of the mounting hole.

[0007] The present invention is further configured such that a stepped portion is formed between the front and rear sections of the mounting through hole, and when the screw drives the rotating head to move forward to its maximum, the front end face of the sealing plug abuts against the side wall of the stepped portion.

[0008] The present invention is further configured such that a guide slope with a gradually decreasing diameter is formed on the side wall of the rear section of the mounting through hole and near the rear end of the front section.

[0009] The present invention is further provided with sealing rings between the shower head connector and the mounting through hole, and between the screw and the mounting through hole.

[0010] The present invention is further configured such that an annular groove is provided at the rear end of the rotating head, and the sealing plug is engaged in the annular groove.

[0011] A faucet includes a water-dividing valve body with shower functions as described above. The faucet includes a faucet body, the water-dividing valve body is disposed in the faucet body, the faucet body is connected to a cold water pipe communicating with a first water inlet and a hot water pipe communicating with a second water inlet, the top of the faucet body is provided with a handle for driving the valve body to swing, and the bottom of the faucet body is screwed with a water outlet pipe communicating with a second water outlet.

[0012] The outstanding and beneficial technical effects of this utility model compared to the prior art are: 1. This utility model provides a highly integrated and compact two-function water valve body, which integrates the switching mechanism for bathtub water outlet and shower water outlet into the columnar valve body, rather than being independently external, which greatly saves the installation space inside the faucet; at the same time, by using a valve body, the number of parts and external pipe connections are reduced, simplifying the overall structure and reducing material costs.

[0013] 2. The stepped section provided by this utility model provides effective limiting, allowing the sealing plug to abut against it, limiting the stroke, ensuring the sealing performance of the second outlet, enhancing the sealing reliability in this state, and preventing water flow cross-contamination; at the same time, the front section of the matching nut end can effectively allow the rotating head to move horizontally without rotating relative to it.

[0014] 3. The guide slope provided by this utility model further enables the sealing plug to seal the second outlet more tightly.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1 — Figure 5 : A water distribution valve body with dual shower functions includes a cylindrical water distribution core 1. A first inlet 10 and a second inlet 11 are formed at the top of the water distribution core 1 through a first flow channel and a second flow channel, respectively. A first outlet 12 is provided at the upper end of the water distribution core 1. A switch valve body 2 is provided at the top of the water distribution core 1, enabling communication between the first inlet 12 and the first outlet 12, or between the second inlet 13 and the second outlet 12. An installation through hole 3 extending in the front-to-back direction is provided inside the water distribution core 1. The first water outlet 12 is connected to the upper wall of the mounting through hole 3. The rear end of the mounting through hole 3 is sealed with a shower head connector 30. The bottom of the water distribution core 1 is provided with a second water outlet 13 that is connected to the lower wall of the mounting through hole 3. The first water outlet 12 and the second water outlet 13 are not vertically aligned. The front end of the mounting through hole 3 is rotatably connected with a screw 4. The rear end of the screw 4 extends into the mounting through hole 3 and is screwed with a rotating head 5. A sealing plug 50 is snapped onto the rotating head 5. A water guide hole 51 that is open vertically is provided on the rotating head 5.

[0018] When the screw 4 drives the rotating head 5 to move backward to its maximum, the sealing plug 50 seals the shower head connector 30, and the first water outlet 12 is connected to the second water outlet 13 through the water guide hole 51. When the screw 4 drives the rotating head 5 to move forward to its maximum, the sealing plug 50 seals the corresponding mounting through hole 3 above the second water outlet 13, and the first water outlet 12 is connected to the shower head connector 30.

[0019] like Figure 3 As shown, during use, the water distribution valve is placed inside the faucet, with the first and second inlets connected to conventional cold and hot water pipes. Connection to the first inlet and outlet is achieved via valve body switch 2. It is worth noting that, typically, during the rotation of valve body switch 2, both the first and second inlets will connect to the first outlet 12, enabling the output of warm water.

[0020] When switching water circuits, when the screw 4 is rotated and the rotating head is driven to move backward, i.e. towards the shower head connector 30, the sealing plug will block the opening of the shower head connector 30, so that it can only flow out from the second outlet. The water flow enters the water guide hole on the rotating head from the first outlet 12 in sequence, and then flows out from the second outlet 13. When the rotating screw 4 drives the rotating head 5 to move forward, the sealing plug moves forward to seal the second water outlet 13, and then the water flows directly out through the first water outlet 12, the installation through hole 3 and then from the shower head connector 30.

[0021] The switching method described above uses an independent columnar valve body, eliminating the need for a separate external valve body in the water circuit, which greatly saves the installation space inside the faucet.

[0022] At the same time, the structure is easy to operate and the switching feel is quite clear.

[0023] Preferably, the rotating head 5 includes a nut end 52 screwed to the end of the screw 4, the side wall of the nut end 52 is provided with the water guide hole 51, the mounting hole 3 includes a front section and a rear section, the cross section of the front section of the mounting hole 3 is a regular hexagon adapted to the nut end 52, and the second water outlet 13 is provided on the lower side wall of the front section of the mounting hole 3.

[0024] In the above structure, to ensure that the water guide hole 51 in the horizontally moving rotating head 5 can always be connected vertically, the nut end 52 and the front section of the mounting hole 3 are both regular hexagonal, which can effectively prevent the rotating head from rotating relative to each other and keep it in a stable horizontal movement.

[0025] Preferably, a stepped portion 31 is formed between the front and rear sections of the mounting through hole 3. When the screw 4 drives the rotating head 5 to move forward to its maximum, the front end face of the sealing plug 50 abuts against the side wall of the stepped portion 31.

[0026] In the above structure, the stepped portion can limit the sliding stroke of the sealing plug and at the same time ensure the effective sealing state of the second outlet.

[0027] Preferably, a guide slope 32 with a gradually decreasing diameter is formed on the side wall of the rear section of the mounting through hole 3 near the rear end of the front section. This guide slope 32 can generate a certain interference fit when the sealing plug slides forward, thereby enhancing the sealing performance.

[0028] Preferably, sealing rings are provided between the shower head connector 30 and the mounting through hole 3, and between the screw 4 and the mounting through hole 3, to further enhance the sealing effect.

[0029] Preferably, the rear end of the rotating head 5 has an annular groove 53, and the sealing plug 50 is engaged in the annular groove 53. Since the sealing plug 50 is often in a sliding state during use, the annular groove 53 can effectively provide a limit and prevent the sealing plug from falling off.

[0030] A faucet includes the aforementioned water-dividing valve body with shower functions. The faucet includes a faucet body 6, the water-dividing valve body is disposed inside the faucet body 6, the faucet body 6 is connected to a cold water pipe 7 communicating with a first water inlet 10 and a hot water pipe 8 communicating with a second water inlet 11, the top of the faucet body 6 is provided with a handle 9 for driving the valve body 2 to swing, and the bottom of the faucet body 6 is screwed with a water outlet pipe 60 communicating with a second water outlet 13.

[0031] In the aforementioned faucet, a handwheel is installed on the front side of the screw 4 to rotate the screw, thereby facilitating the switching of water channels.

[0032] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
