[0027] In order to enable those skilled in the art to better understand the solutions of the present application, the following will clearly and completely describe the technical solutions in the embodiments of the present application in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0028] With the continuous development of the city, high-rise housing buildings in the city are constantly springing up. For those families living on high floors or far away from the water supply station, due to the limited urban water supply pressure, the water pressure for household use is insufficient and the water flow rate is slow.

[0029] Currently, only the inlet solenoid valve is used to control the water supply into the washing machine inside the washing machine on the market. The washing machine cannot detect the water pressure. When the water pressure is low, the water inlet is slow. When the inlet solenoid valve is continuously powered on and the washing machine has been filled with water to the set water level, the inlet solenoid valve is closed, or the opening time of the inlet solenoid valve is fixed. When the water pressure is low, the washing machine fills less water, resulting in an over-time water inlet alarm for the washing machine and causing user complaints.

[0030] Therefore, during the process of using a washing machine to wash clothes, due to insufficient water pressure, the water inlet speed is slow, the amount of water inlet is small, resulting in a long water inlet time, the washing machine gives a water inlet alarm, and the clothes cannot be washed clean. Due to the water pressure problem, people's quality of life is affected.

[0031] The embodiment of the present application provides a water inlet solenoid valve with a pressurizing device and a water-using cleaning device, which can realize that when the water pressure is lower than the set value, the booster pump starts to increase the water inlet pressure, and when the water pressure is higher than the set value, the booster pump is in a closed state, which can effectively improve the water-using problems caused by low water pressure, improve the user experience, and solve the problems of slow water inlet speed and small water inlet amount due to insufficient water pressure in the related art, resulting in a long water inlet time.

When the water pressure monitored by the pressure switch 2 is lower than the set water pressure, the booster pump 3 is controlled to work, and the water is pressurized and discharged through the first water inlet pipe 101, the first water outlet pipe 102, the second water inlet pipe 301 and the second water outlet pipe 302. When the water pressure is lower than the set value, the booster pump 3 starts to increase the inlet water pressure. When the water pressure is higher than the set value, the booster pump 3 is in the closed state, which can effectively improve the water use problem caused by low water pressure, improve the user experience, and solve the problem of long inlet time caused by insufficient water pressure, slow inlet speed and less inlet water in the related technology.

The filtered impurities are stored between the first filter plug 4 and the second filter plug 5 for convenient subsequent cleaning. At the same time, since both the first filter plug 4 and the second filter plug 5 are arched, the area of impact between the first filter plug 4 and the second filter plug 5 and the water can be increased, improving the filtration degree.

[0048] Specifically, the municipal water is connected to the water inlet solenoid valve body 1, and the municipal water flows into the interior of the water inlet solenoid valve body 1 through the first water inlet pipe 101. Through the adjustment and control of the water inlet solenoid valve body 1, the water flow enters the first water inlet pipe 101 and then enters the second water inlet pipe 301 of the booster pump 3, and is discharged through the second water outlet pipe 302 of the booster pump 3. When the water pressure monitored by the pressure switch 2 is lower than the set water pressure, the booster pump 3 is controlled to work, and the water is boosted and discharged through the first water inlet pipe 101, the first water outlet pipe 102, the second water inlet pipe 301 and the second water outlet pipe 302. It is realized that when the water pressure is lower than the set value, the booster pump 3 starts to increase the water inlet pressure, and when the water pressure is higher than the set value, the booster pump 3 is in a closed state, which can effectively improve the water use problem caused by low water pressure, improve the user experience, and solve the problem of slow water inlet speed, less water inlet and long water inlet time due to insufficient water pressure in the related technology.
