Description

Technical Field

[0001] This utility model relates to the field of sensor faucets, specifically to an improved sensor faucet. Background Technology

[0002] Existing sensor faucets are generally bulky and complex in structure. If the dustproof and waterproof performance of the sensing device and solenoid valve is inadequate, the solenoid valve or sensor can easily be damaged. The solenoid valve is located under the countertop where the faucet is located, which not only occupies space under the countertop but also makes it susceptible to damage from water seepage.

[0003] In view of this, the inventor conducted in-depth research on the aforementioned deficiencies in the prior art, which led to the creation of this case. Utility Model Content

[0004] The main purpose of this utility model is to provide an improved sensor faucet, which has the characteristics of compact structure and the solenoid valve is not easily damaged.

[0005] To achieve the above objectives, the solution of this utility model is:

[0006] An improved sensor faucet includes a faucet housing, a solenoid valve, an inlet mounting base, and a sensor. The solenoid valve is connected to the inlet mounting base to control the flow of water between the inlet channel of the inlet mounting base and the outlet channel of the solenoid valve. The sensor is electrically connected to the solenoid valve. The solenoid valve and the inlet mounting base are fixedly installed and completely located within the inner cavity of the faucet housing. An installation window is formed on the side wall of the faucet housing, and the sensor is fixedly installed in the installation window. The outlet channel of the solenoid valve is connected to the outlet of the faucet housing via a water pipe.

[0007] Furthermore, the faucet housing is made of zinc alloy.

[0008] Furthermore, a threaded hole is formed on the water inlet mounting base, and a fixing screw is installed in the threaded hole. The fixing screw is locked to the inner wall of the faucet housing.

[0009] Furthermore, a limiting protrusion is formed on the water inlet mounting base, and a limiting groove is formed at the bottom of the solenoid valve, with the limiting protrusion and the limiting groove engaging with each other; a locking structure is also provided for the water inlet mounting base and the bottom of the solenoid valve.

[0010] Furthermore, the installation window is located on the side wall of the column on the front side of the faucet housing.

[0011] Furthermore, the lower part of the inner wall of the faucet housing has an internal thread, and the lowest point of the water inlet mounting seat is higher than the internal thread.

[0012] Furthermore, the water inlet channel of the water inlet mounting base is detachably connected to a water supply pipe.

[0013] Furthermore, the sensor is connected to a power source located outside the faucet housing.

[0014] With the above structure, the improved sensor faucet of this utility model has at least the following beneficial effects:

[0015] 1. The control valve, consisting of the solenoid valve and the inlet mounting bracket, is installed inside the faucet housing. Water is then transported from the solenoid valve's outlet channel to the faucet housing's outlet via a water pipe. This not only avoids the solenoid valve occupying space below the countertop, but also, due to its elevated position, prevents water accumulation on its outer surface, thus extending its service life. Furthermore, the location of the solenoid valve and inlet mounting bracket within the faucet housing allows for a more compact piping system.

[0016] Second, the faucet body is made of zinc alloy, which facilitates casting. Furthermore, due to the water pipe design, the faucet body has a spout at the outlet, preventing water from contacting the faucet body and meeting the requirements for lead-free water flow.

[0017] Third, the water inlet mounting base is positioned by the cooperation of the limiting protrusion and the limiting groove at the bottom of the solenoid valve. This allows different faucet structures to install different types of water inlet mounting bases and connect them to the solenoid valve while sharing the same solenoid valve. This eliminates the need for a complete design of the control valve for each faucet, which helps save on mold costs.

[0018] Compared with the prior art, this utility model connects the solenoid valve to the water inlet mounting base and fixes the connected whole inside the faucet housing, making the faucet structure more compact and preventing downward water from falling onto the solenoid valve and affecting its lifespan.

Detailed Implementation

[0025] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0026] like Figures 1 to 4 As shown, this is an improved sensor faucet according to the present invention, comprising a faucet housing 1, a solenoid valve 2, a water inlet mounting base 3, and a sensor 4; the solenoid valve 2 is connected to the water inlet mounting base 3 below to control the water flow between the water inlet channel 31 of the water inlet mounting base 3 and the water outlet channel 21 of the solenoid valve 2; the sensor 4 is electrically connected to the solenoid valve 2; the solenoid valve 2 and the water inlet mounting base 3 are fixedly installed and completely located within the inner cavity of the faucet housing 1; an installation window 11 is formed on the side wall of the faucet housing 1, and the sensor 4 is fixedly installed in the installation window 11; the water outlet channel 21 of the solenoid valve 2 is connected to the water outlet of the faucet housing 1 through a water pipe 22.

[0027] Thus, the improved sensor faucet of this utility model houses the control valve, consisting of the solenoid valve 2 and the inlet mounting base 3, inside the faucet housing 1. Water is then transported from the outlet channel 21 of the solenoid valve 2 to the outlet of the faucet housing 1 via the water pipe 22. This not only avoids the solenoid valve 2 occupying space below the countertop, but also, due to its elevated position, prevents water accumulation on its outer surface, thus extending its service life. Furthermore, the location of the solenoid valve 2 and the inlet mounting base 3 within the faucet housing 1 results in a more compact piping system.

[0028] Preferably, the faucet housing 1 is made of zinc alloy. Using zinc alloy as the faucet housing 1 facilitates casting and processing. Furthermore, due to the water pipe 22, the water outlet of the faucet housing 1 is equipped with a spout, ensuring that the water flow does not contact the faucet housing 1, thus meeting the requirement of lead-free water flow.

[0029] Preferably, the water inlet mounting base 3 has a threaded hole 32, and a fixing screw (not shown in the figure) is installed in the threaded hole 32. The fixing screw is locked to the inner wall of the faucet housing 1. During installation, the fixing screw extends from the bottom of the faucet housing 1, and the worker uses an L-shaped wrench to tighten the fixing screw to lock it into the corresponding countersunk hole (not shown in the figure) on the inner wall of the faucet housing 1.

[0030] Preferably, a limiting protrusion 33 is formed on the water inlet mounting base 3, and a limiting groove 23 is formed at the bottom of the solenoid valve 2. The limiting protrusion 33 and the limiting groove 23 are engaged with each other. A locking structure is also provided between the water inlet mounting base 3 and the bottom of the solenoid valve 2. The water inlet mounting base 3 is positioned by the cooperation of the limiting protrusion 33 and the limiting groove 23 at the bottom of the solenoid valve 2. This allows for different faucet structures to be connected to the solenoid valve 2 using different types of water inlet mounting bases 3, while sharing the same solenoid valve 2. This eliminates the need for a complete design of the control valve for each faucet, thus saving mold costs.

[0031] Preferably, the mounting window 11 is located on the upright side wall of the faucet housing 1 facing forward. The sensor 4 is mounted from the inside of the faucet housing 1 outward into the mounting window 11. The sensor 4 is positioned facing forward to facilitate sensing the user's hand, making it more convenient to use.

[0032] Preferably, the lower part of the inner wall of the faucet housing 1 has an internal thread 12, and the lowest point of the water inlet mounting base 3 is higher than the internal thread 12. The internal thread 12 is used to install the threaded base 6, which facilitates the faucet housing 1 to be fixedly installed on the mounting hole on the countertop.

[0033] Preferably, the water inlet channel 31 of the water inlet mounting base 3 is detachably connected to a water supply pipe (not shown in the figure), which is connected to a tap water pipe. Preferably, the sensor 4 is connected to a power source (not shown in the figure), which is located outside the faucet housing 1.

[0034] Compared with the prior art, this utility model connects the solenoid valve 2 with the water inlet mounting base 3 and fixes the connected whole inside the faucet housing 1, making the faucet structure more compact and preventing downward water from falling onto the solenoid valve 2 and affecting its lifespan.

[0035] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
