Description

Technical Field

[0001] The present invention belongs to the technical field of faucets, and particularly relates to a solenoid valve assembly. Background Art

[0002] As Figure 1 shown, currently, due to the unreasonable design of the solenoid valve and the water outlet pipe in the round pipe wall-mounted faucet, the overall diameter of the round pipe wall-mounted faucet is relatively large, consuming more materials and having a higher production cost. For example, the patent with publication number CN201034202Y discloses a new type of induction faucet. The solenoid valve of this faucet is installed in the center of the housing, and the water outlet pipe is arranged on one side of the solenoid valve. The diameter of the whole faucet is a circle with the solenoid valve as the center and the radius of the solenoid valve plus the diameter of the water outlet pipe as the radius of the faucet. There are a large number of gaps in the faucet, such as the gap between the solenoid valve and the housing. Due to the structural design of the water outlet pipe, the gap between the water outlet pipe and the solenoid valve is also relatively large, generally resulting in a relatively large overall size of the faucet, consuming more materials and having a high production cost. In addition, due to the excessive gap between the solenoid valve and the housing, the pressure on the connection screws of the solenoid valve is relatively large during long-distance transportation, and the screws are prone to loosen, resulting in water leakage due to poor sealing. Summary of the Invention

[0003] The technical problem to be solved by the present invention is how to reasonably design the solenoid valve assembly so that the overall size of the round pipe wall-mounted faucet can be made smaller, thereby achieving the purpose of reducing material consumption and cost.

The water outlet pipe is installed on the side of the valve seat, and the side of the water outlet pipe close to the valve seat is a plane. The water outlet pipe is radially provided with a water passage groove. The end face of the connection part between the water outlet pipe and the valve seat is a D-shaped structure.

[0006] Preferably, the cross-section of the water passage groove is a racetrack shape to maximize the water output.

[0025] The present invention will be further described below with reference to the embodiments.

[0026] Embodiment 1

[0027] As Figures 2 - 7The shown solenoid valve 1 assembly of the round tube wall-mounted faucet. The faucet includes an induction module, a battery assembly 6, a water outlet nozzle 7, and a housing 8, and includes a solenoid valve 1, a valve seat 2, and a water inlet seat 3. The solenoid valve 1 is fixed on the valve seat 2. It should be noted that the valve seat 2 is eccentrically installed on the water inlet seat 3 to create a space for installing the outlet pipe 4, and the outlet pipe 4 is arranged in this space. In this embodiment, the lower end of the water inlet seat is provided with external threads or internal threads, and the induction module is purchased on the market, which is prior art. In order to facilitate the water inlet of the valve seat 2, in this embodiment, the water inlet seat 3 is provided with an eccentric water inlet hole 31. By eccentrically installing the solenoid valve on the water inlet seat in this embodiment, a installation position for the outlet pipe can be reserved above the water inlet seat, maximizing the utilization rate of the entire space, so that the housing of the entire faucet can be made relatively smaller, achieving the purpose of reducing materials and costs. Currently, the water outlet hole 21 of the valve seat 2 on the market is arranged above the valve seat 2, and there is a complex water outlet channel inside the valve seat 2, making the size of the valve seat 2 relatively large and the processing difficult. In this embodiment, the water outlet hole 21 of the valve seat 2 is arranged on the side of the valve seat 2. And the surface of the valve seat 2 with the water outlet hole 21 is designed as a flat surface, and the outlet pipe 4 is installed on this flat surface, and the corresponding installation surface of the outlet pipe 4 is also designed as a flat surface. In this embodiment, the valve seat 2 has a D-shaped structure. This further reduces the installation space, enabling the diameter of the faucet housing to be made smaller, thus saving costs.

[0028] In this embodiment, the outlet pipe 4 is a hollow pipe with one end open and one end closed. The part of the outlet pipe 4 closely attached to the valve seat 2 is a flat surface. The outlet pipe 4 is radially provided with a water through groove 41, and the cross-section of the water through groove is a racetrack-shaped structure. Due to the fixed positions of the screw holes on both sides of the water through groove, the installation space of the water through groove is limited. In order to make full use of the limited space, the water through groove is set as a racetrack shape, maximizing the use of space and maximizing the water output. The end face of the connection part between the outlet pipe 4 and the valve seat 2 has a D-shaped structure. In this embodiment, a sealing ring is provided between the outlet pipe 4 and the valve seat 2, and a sealing ring is provided between the valve seat 2 and the water inlet seat 3. In this embodiment, the solenoid valve 1 and the valve seat 2 are made of plastic material. Since threads need to be provided on the water inlet seat 3, in order to prevent the threads from slipping, the water inlet seat 3 in this embodiment is made of metal material, which can ensure the strength of the product while saving costs. In this embodiment, the part where the lower end of the outlet pipe is connected to the valve seat is designed as a D-shaped structure, further reducing the installation space. It can be seen from the drawings that the upper end of the outlet pipe is a round pipe, and the distance between it and the coil housing of the solenoid valve is almost zero, while in the drawings of the background technology, it can be clearly seen that there is a relatively large gap between the outlet pipe and the coil housing of the solenoid valve. It can be seen that the solenoid valve assembly structure in this embodiment is more compact, enabling the overall size of the faucet to be made smaller.

[0029] In this embodiment, the end water outlet of the outlet pipe 4 is provided with a tapered structure with an inner diameter gradually increasing from inside to outside. The design of the tapered hole facilitates the connection of pipes, making the sealing between the connected pipes better.

[0030] In this embodiment, the solenoid valve 1 and the valve seat 2 are connected to the water inlet seat 3 by two screws. Among them, the four walls of the valve seat 2 where the screws are installed, the outer wall on the eccentric side of the valve seat 2, and the outer wall of the water outlet pipe 4 are adapted to the inner wall of the round pipe. At the same time, the valve seat of the solenoid valve and the water outlet pipe can both abut against the inner wall of the housing, so that the solenoid valve will not be suspended during transportation, reducing the stress on the screws and ensuring that the product will not be damaged during transportation.

[0031] In actual installation, since the position of the water outlet of the faucet is fixed, and to ensure that the water outlet of the faucet is installed in a specified direction and at the same time ensure that the water inlet seat 3 at the lower end of the faucet is fixed and does not leak water, it is very difficult to achieve. This places strict requirements on the length of the thread and the tightening position of the water inlet seat 3 at the lower end of the faucet, because it is impossible to ensure that there is no water leakage when the water inlet seat 3 is tightened by one turn. Therefore, in this embodiment, a plurality of radial mounting holes 32 are provided on the side of the water inlet seat 3. During installation, the nearest mounting hole 32 can be selected according to needs, so that the position of the water outlet of the faucet is in the set direction, and at the same time, it can be ensured that the connection between the water inlet seat 3 and the water inlet pipe is sealed and does not leak water. A filter screen 5 is provided in the water inlet seat 3 described in this embodiment.

[0032] At present, when many faucets are installed, it is difficult to rotate the handle under the washbasin. In order to facilitate installation, the water inlet seat 3 is first connected to the washbasin, and then components such as the solenoid valve 1 are installed. Since the outer circumference of the water inlet seat 3 is circular and the lower part is a circular thread, it is not easy to tighten when connecting it to the water pipe. To solve this problem, in this embodiment, the water inlet hole 31 of the water inlet seat 3 is an internal hexagonal hole convenient for inserting a wrench. It can also be a hole of other shapes convenient for cooperation with other types of wrenches. In this way, the wrench can be directly inserted into the water inlet hole 31 on the water inlet seat 3 for installation, and it is much easier to install by turning the wrench from the upper end of the water inlet seat 3.

[0033] Embodiment Two

[0034] As Figure 8 and Figure 9 shown, the difference between this embodiment and Embodiment One is that in this embodiment, the solenoid valve 1 and the valve seat 2 are integrally square in structure, and four screws are connected between the solenoid valve 1, the valve seat 2 and the water inlet seat 3. In this embodiment, the valve seat 2 is also eccentrically installed on the water inlet seat 3.

[0035] This embodiment is mainly used for in-wall installation, which is convenient for installation, saves space, has a beautiful appearance, and is convenient for maintenance.

[0036] The basic principles, main features and advantages of the present invention have been shown and described above. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, simple modifications and substitutions made by ordinary technical personnel in the art are within the protection scope of the present invention.

[0037] The present invention provides a solenoid valve assembly for a round pipe wall-mounted faucet, which includes an induction module, a solenoid valve, a valve seat, a water inlet seat and a water outlet pipe. The solenoid valve is fixed on the valve seat. The water outlet pipe is a hollow pipe with one end open and one end closed. The water outlet pipe is installed on the side of the valve seat, and the side of the water outlet pipe in close contact with the valve seat is a plane. A water passage groove is provided radially on the water outlet pipe. By eccentrically installing the solenoid valve on the water inlet seat, the installation position of the water outlet pipe can be reserved above the water inlet seat, maximizing the utilization rate of the entire space, so that the outer shell of the entire faucet can be made relatively smaller, more beautiful as a whole, and the purpose of reducing materials and costs can be achieved.
