Description

Technical Field

[0001] The invention relates to the field of induction faucets, in particular to a solenoid valve and an induction faucet control box. Background Art

[0002] Most of the faucets currently used in the market are manual faucets or automatic induction faucets. Manual faucets use manpower to open or close the faucet valve, while induction faucets use sensors to sense the human body, and the controller controls the solenoid valve to automatically open or close the valve according to the sensor signal. Manual faucets waste more manpower than induction faucets, and are prone to waste water resources due to reasons such as forgetting to close the faucet. Because there is no induction water outlet device, the faucet must be touched every time the valve is opened and closed, causing cross infection and unsanitary. Induction faucets can open and close the valve in time, effectively reducing the problem of water resource waste, and do not require contact, effectively preventing the spread of bacteria. However, when the electromagnetic component of the existing induction faucet fails, that is, when the electromagnetic valve has no power supply or the electromagnetic valve component inside the electromagnetic valve is damaged or the controller that controls the electromagnetic valve is damaged, it is generally impossible to control the water path by manual operation, which makes the water path control function of the induction faucet invalid, resulting in the induction faucet being unusable, and there are limitations in use.

[0028] The valve cover 2 is installed on the top of the valve body 1 by means of flange connection. A mounting cavity 21 is provided in the valve cover 2 for mounting the solenoid valve core 3 .

[0029] The solenoid valve core 3 is fitted in the installation cavity 21; the solenoid valve core 3 includes a moving iron core 31 movably arranged in the installation cavity 21, an electromagnetic component 32 fixed in the installation cavity 21 and used to drive the moving iron core 31 to move upward, and a return spring 33 located between the moving iron core 31 and the electromagnetic component 21 and used to drive the moving iron core 31 to move downward; the lower end of the moving iron core 31 penetrates into the valve cavity 12 from the first installation hole 15 and movably blocks the valve port 121. The electromagnetic assembly 32 includes a sleeve 321, a coil 322 and a static iron core 323; the sleeve 321 is inserted into the installation cavity 21 of the valve cover 2, and an annular cavity 22 is formed between the sleeve 321 and the inner wall of the installation cavity 21, and the lower end of the sleeve 321 may be provided with an outwardly protruding annular sheet 3211, and the annular sheet 3211 is clamped between the valve cover 2 and the valve body 1 to fix the sleeve 321; the coil 322 is fitted in the annular cavity 22 and sleeved on the sleeve 321; the static iron core 323 is fixed in the sleeve 321; the moving iron core 31 is movably inserted into the sleeve 321 and is located below the static iron core 323, and the lower end of the moving iron core 31 may be equipped with a sealing gasket 311 to ensure that the valve port 121 is completely blocked; the reset spring 33 is fitted in the sleeve 321 and is located between the moving iron core 31 and the static iron core 323.
