Description

Technical Field

[0001] This utility model relates to the field of manual and automatic faucets. Background Technology

[0002] Existing manual and automatic faucets include a manual water outlet circuit and an automatic water outlet circuit. When the automatic valve of the automatic water outlet circuit is damaged and cannot dispense water, the manual valve can be used to control the water flow from the manual water outlet circuit.

[0003] For example, Chinese patent CN202040379U discloses a manual and automatic kitchen faucet. The faucet body is provided with a cold water branch channel to connect the cold water inlet channel and the mixed water outlet channel; a solenoid valve to control the opening and closing of the cold water branch channel or the mixed water outlet channel; and an infrared sensor installed on the faucet body to establish a sensing area within a predetermined distance of the faucet to detect objects entering and control the solenoid valve to open or close for a set time, so that the faucet has both manual water dispensing and real-time, fast and short-term automatic water dispensing functions.

[0004] For example, the valve core seat and valve core module assembly with publication number CN115681569A also have manual and automatic water dispensing functions, and they also adopt the structure of the motor being placed at the bottom.

[0005] The problem with existing technology is that its solenoid valve core is located at the bottom, which means that after the water enters from the bottom and turns to a horizontal direction, it still has to flow upward, downward, and upward again before it can automatically discharge water. This results in high water flow resistance for automatic water discharge. Utility Model Content

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a manual / automatic faucet with a simple water flow structure and smooth automatic water dispensing.

[0007] The technical solution adopted by this utility model to solve the problem is: a manual / automatic faucet, comprising: a body, wherein the bottom of the body is provided with a first water inlet pipe, a second water inlet pipe, and interconnected mounting holes and a main water outlet pipe; the side of the body is provided with a first water outlet pipe and a second water outlet pipe, both of which are connected to the upper part of the main water outlet pipe; a temperature probe is installed at the bottom of the mounting hole; and an electric valve core, wherein the electric valve core is installed on the upper part of the body. The valve core is used to control the connection and disconnection between the second water outlet pipe and the main water outlet pipe; the water valve includes a water valve chamber, which is connected to a first water inlet, a second water inlet, a first water outlet, and a second water outlet; the second water outlet is connected to the second water outlet pipe, and the water valve can control the connection and disconnection between the first water outlet and the first water outlet pipe, the first water inlet and the first water inlet pipe, and the second water inlet and the second water inlet pipe; both the first water inlet pipe and the second water inlet pipe are equipped with check valves.

[0008] As a preferred technical solution, the water valve includes a stationary valve plate, a moving valve plate, and a handle. The handle is connected to the moving valve plate and controls the rotation of the moving valve plate. The second water outlet is located at the center of the stationary valve plate and the moving valve plate. The moving valve plate has three internal through holes, and the stationary valve plate has three external through holes. The three internal through holes and the three external through holes partially overlap, and the overlapping part forms the first water inlet, the second water inlet, and the first water outlet.

[0009] As a preferred technical solution, the system further includes a housing, which includes a vertically tubular housing body and an outwardly protruding tubular branch pipe. The housing body is connected to the branch pipe, the housing body is disposed within the housing body, and a circuit board is disposed within the branch pipe. The circuit board is equipped with a display screen, and the electric valve core and the temperature probe are electrically connected to the circuit board. The system also includes an infrared sensor, which is electrically connected to the circuit board.

[0010] The beneficial effects of this utility model are:

[0011] Check valves are installed on the first and second water inlet pipes on the main body to prevent water from flowing back into the water.

[0012] An electric valve core is installed on the upper part of the main body. The automatic water outlet only needs to enter the second water outlet pipe upwards and then enter the main water outlet pipe downwards. The water outlet pipe is simple, with low water resistance and a compact structure. Attached Figure Description

[0029] Reference Figures 1 to 10 A manual / automatic faucet, comprising:

[0030] The main body 1 has a first water inlet pipe 13 and a second water inlet pipe 14 at its bottom, as well as an interconnected mounting hole 11 and a main water outlet pipe 12. The side of the main body 1 has a first water outlet pipe 15 and a second water outlet pipe 16, both of which are connected to the upper part of the main water outlet pipe 12. A temperature probe 5 and an electric valve core 3 are installed at the bottom of the mounting hole 11. The electric valve core is installed on the upper part of the main body 1 and is used to control the connection between the second water outlet pipe 16 and the main water outlet pipe. The water valve 2, which controls the on / off state of 12, includes a water valve chamber 20, which is connected to a first water inlet 23, a second water inlet 24, a first water outlet 25, and a second water outlet 26. The second water outlet 26 is connected to the second water outlet pipe 16. The water valve 2 can control the on / off state of the first water outlet 25 and the first water outlet pipe 15, the first water inlet 23 and the first water inlet pipe 13, and the second water inlet 24 and the second water inlet pipe 14. In a preferred embodiment, both the first water inlet pipe 13 and the second water inlet pipe 14 are equipped with check valves.

[0031] Operating principle: The first inlet pipe 13 and the second inlet pipe 14 are used for hot water or cold water respectively. The water valve 2 can control the connection and disconnection between the first outlet hole 25 and the first outlet pipe 15, the first inlet hole 23 and the first inlet pipe 13, and the second inlet hole 24 and the second inlet pipe 14. Therefore, it can control the inflow of hot water, cold water, and the outflow of water from the first outlet pipe 15. Normally, the first outlet pipe 15 does not need to output water. Only when the electric valve core 3 is damaged, i.e., the second outlet pipe 16 cannot be connected to the main outlet pipe 12, is it necessary to use the water valve 2 to control the connection between the first outlet hole 25 and the first outlet pipe 15 so that the first outlet pipe 15 can output water to the main outlet pipe 12.

[0032] The advantage of this utility model is that an electric valve core is installed on the upper part of the main body 1, and the automatic water outlet circuit only needs to enter the second water outlet pipe 16 upward and then enter the main water outlet pipe 12 downward. The automatic water outlet circuit is simple and has low water resistance.

[0033] In a preferred embodiment, the water valve 2 includes a stationary valve plate 21, a moving valve plate 22, and a handle 201. The handle 201 is connected to the moving valve plate 22 and controls its rotation. A second water outlet 26 is located at the center of the stationary valve plate 21 and the moving valve plate 22. The moving valve plate 22 has three internal through holes 211, and the stationary valve plate 21 has three external through holes. The three internal through holes 211 and the three external through holes 222 partially overlap, and the overlapping portion forms the first water inlet hole 23, the second water inlet hole 24, and the first water outlet hole 25. The water valve cavity 20, the second water outlet hole 26, and the second water outlet pipe 16 are always connected. By rotating the handle 201, the relative angle between the stationary valve plate 21 and the moving valve plate 22 is adjusted, thereby adjusting the area of ​​the first water inlet hole 23, the second water inlet hole 24, and the first water outlet hole 25. The area of ​​the first water inlet hole 23, the second water inlet hole 24, and the first water outlet hole 25 can be adjusted to 0.

[0034] In a preferred embodiment, the system further includes a housing 4, which comprises a vertically tubular housing body 41 and an outwardly protruding tubular branch pipe 42. The housing body 41 is connected to the branch pipe 42. The housing body 41 is disposed within the housing body 41, and a circuit board is disposed within the branch pipe 42. A display screen 43 is mounted on the circuit board. The electric valve core 3 and the temperature probe 5 are electrically connected to the circuit board. An infrared sensor (not shown) is also included and is electrically connected to the circuit board. The infrared sensor detects a human hand and then controls the electric valve core 3 to open. The temperature probe 5 detects the outlet water temperature, and the display screen 43 displays the water temperature.

[0035] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
