Problems solved by technology

[0006] However, since the high-pressure value and low-pressure value of the existing high-pressure switch are generally fixed and cannot be adjusted, the interval between the high-pressure value and the low-pressure value changes very little, which will cause the booster pump to start frequently

Embodiment 1

[0028] A high voltage switch such as figure 1 , figure 2 As shown, it includes a water pipe joint 1 with a water flow channel 11 inside. The water pipe joint 1 is a quick-connect joint, which enables the high-pressure switch 100 to be quickly connected to a water pipe that needs to check the water pressure. The water pipe joint 1 is provided with a sensor for detecting the water pressure in the water flow channel 11 and outputting a water pressure signal. The sensor includes a sensor diaphragm 21, a sensor circuit 23 and a conversion circuit board 22. The sensor circuit 23 is provided with a piezoresistor, and the sensor film One side of the sheet 21 communicates with the water flow channel 11 , and the other side is printed with a sensor circuit 23 connected to a conversion circuit board 22 , and a signal output line 24 is provided on the conversion circuit board 22 .

[0029] The water pipe joint 1 is provided with a storage tank 12 for sensor installation and a water inle...

Embodiment 2

[0033] The water purifier comprises a raw water inlet pipe 3, a water pump 4 and a water inlet solenoid valve 5 are arranged on the raw water inlet pipe 3, a control module connected to the water pump 4 and the water inlet solenoid valve 5 is also included, and the water inlet of the raw water inlet pipe 3 The high pressure switch 100 in Embodiment 1 is provided at the place, and the control module is used to process the water pressure signal detected by the high pressure switch 100 and control the water pump 4 and the water inlet solenoid valve 5 according to the processing results.

[0034] In this embodiment, a high-pressure switch 100 is installed at the water inlet of the raw water inlet pipe 3 of the water purifier, and the high-pressure switch 100 is installed on the water inlet solenoid valve 5. At this time, the high-pressure switch 100 can detect the water pressure value in the raw water inlet pipe 3 in real time. , the specific detection method is:

[0035] The sens...

Embodiment 3

[0037] Such as image 3 As shown, it is the same as Embodiment 2, except that it also includes an RO reverse osmosis membrane filter element 6 connected to the raw water inlet pipe 3, that is, the high pressure switch 100 is set on the reverse osmosis water purifier. There is also a pre-filter 8 on the water inlet pipe, through which the raw water is pretreated to improve the water purification effect, and at the same time it also protects the RO reverse osmosis membrane filter 6, and the RO reverse osmosis membrane filter 6 is connected to There are a concentrated water outlet pipe 61 and a pure water outlet pipe 62, and the pure water outlet pipe 62 is provided with the high pressure switch 100 in Embodiment 1 and the pressure tank 7 for storing pure water.

[0038] The high pressure switch 100 is installed in the pure water channel of the reverse osmosis water purifier to be used to control the start and stop of the water pump 4, because the average value of the high and lo...

Abstract

The invention relates to the field of water purifiers, and discloses a high-pressure switch and a water purifier using the high-pressure switch. The high-pressure switch comprises a water pipe connector (1), and further comprises a fixing part (26) and a sensor, wherein a water flow channel (11) is arranged in the water pipe connector (1); the sensor is used for detecting water pressure in the water flow channel (11) and outputting a water pressure signal, is arranged in the water pipe connector (1), is fixed by the fixing part (26), and comprises a sensor diaphragm (21) and a conversion circuit board (22); one side of the sensor diaphragm (21) communicates with the water flow channel (11); a sensor circuit (23) connected with the conversion circuit board (22) is printed on the other side of the sensor diaphragm (21); and a signal output line (24) is arranged on the conversion circuit board (22). As the pressure sensor is arranged in the high-pressure switch disclosed by the invention, any pressure value within a pressure range can be detected by the pressure sensor; not only can components in a water path be controlled, but also the detecting function can be achieved; and the high-pressure switch further has the advantages of being small in size, easy to mount, and the like.

Description

technical field [0001] The invention relates to the field of water purifiers, in particular to a high-voltage switch in the water purifier. Background technique [0002] In the past two years, the penetration rate of household water purifiers has increased a lot, especially reverse osmosis water purifiers, accounting for half of the entire household water purifiers, and there is an increasing trend. [0003] At present, the pure water produced by household reverse osmosis water purifiers on the market is stored in a pressure tank with an air bag. At the beginning, the air pressure of the air bag is about 0.05MPa. When the pure water is continuously injected, the air bag is compressed. After the value, stop injecting water. In the process of producing pure water, whether to produce water is controlled by the high-pressure switch in the pure water circuit. When the pressure of the pressure tank drops to a certain value, the high-pressure switch is closed, the water pump is st...
