Technical field

The invention relates to a solenoid valve, especially an integrated solenoid valve, in particular to a solenoid valve used in a smart toilet.

Background technique

The current smart toilet products include split toilets and integrated toilets. Both types of toilets contain smart toilet lids. Almost all of the smart toilet lids are equipped with a separate pressure reducing valve and its control waterway to clean the human body. The toilet drain is flushed through a separate flush valve.

In split and integrated toilets, the pressure reducing valve and flushing valve are independent and coexisting, and tap water is input through the same water inlet. In the prior art, the pressure reducing valve is installed in the toilet cover, which occupies a lot of space in the toilet cover, and the toilet cover becomes thick and swollen and not portable. The flush valve is generally installed separately in the ceramic toilet bowl. Due to the large space in the ceramic toilet bowl, the space cannot be fully utilized; if more space is occupied, the overall appearance of the toilet will not be affected. In addition, the sewage flushing valve for flushing urine and feces and the pressure-reducing cleaning valve for cleaning the human body are installed separately, which increases the cost.

With the popularization of smart toilets, people have higher and higher requirements for the cost performance of smart toilets, especially for smart toilet flushing performance and water saving. In the current technology, a flow meter or pressure sensor is generally installed at the front end of the flushing valve to realize the flushing performance and water saving function of each water pressure section. However, the realization of the above-mentioned technical means will lead to increased costs, complex structures, and large product footprints.

Summary of the invention

The present invention aims to solve the problems of the sewage flushing valve of the smart toilet and the pressure-reducing and cleaning valve for cleaning the human body in the prior art, which are independent of each other and are installed separately, resulting in large space occupation, high cost, and heavy toilet cover. The pressure-flushing integrated valve has a compact structure, small overall volume, convenient installation, low overall cost, and can make the toilet cover thin and easy to use.

In order to solve the above problems, the technical solution adopted by the present invention is to provide a water inlet, a water outlet A and a water outlet B on the valve body, and an electromagnetic pilot valve A and an electromagnetic pilot valve B are also provided on the water inlet channel of the valve body. The special feature is that the valve body is provided with a pressure reducing valve, a flow sensor communicating with the outlet of the pressure reducing valve, and a cleaning channel with a water outlet C communicating with the outlet of the flow sensor. The electromagnetic pilot valve A, The outlet of the electromagnetic pilot valve of one of the electromagnetic pilot valves B is divided into a flushing water flow and a metering water flow, and the metering water flow is connected with the water inlet of the flow sensor.

It is advisable to provide an atmosphere communication port A on the main water outlet channel A of the electromagnetic pilot valve A, and the air communication port A is provided with a vacuum breaking valve core A, and the main water outlet channel B of the electromagnetic pilot valve B is provided with atmosphere The communication port B is provided with a vacuum break valve core B at the atmosphere communication port B, the cleaning channel is provided with an atmosphere communication port C, and the atmosphere communication port C is provided with a vacuum break valve core C.

The cleaning channel is provided with an overflow port that penetrates the water outlet C, and the other end of the vacuum breaking valve core C at one end relative to the atmosphere corresponds to the overflow port.

The one electromagnetic pilot valve may be the electromagnetic pilot valve B, and the end of the vacuum breaking valve core B in the atmospheric direction corresponds to the end of the vacuum breaking valve core C in the atmospheric direction.

The end of the vacuum breaking valve core B in the atmospheric direction corresponds to the end of the vacuum breaking valve core C in the atmospheric direction. Preferably, the end of the vacuum breaking valve core B in the atmospheric direction and the end of the vacuum breaking valve core C in the atmospheric direction are corresponding. Abut against each other by compression springs.

The present invention is installed in the ceramic body of the smart toilet. Because the present invention is provided with a pressure reducing valve, a flow sensor connected to the outlet of the pressure reducing valve, and a cleaning channel with a water outlet C connected to the outlet of the flow sensor. Therefore, in addition to the electromagnetic pilot valve A and electromagnetic pilot valve B acting as a smart toilet flushing, it can also be used as a human body cleaning, eliminating the drawback that the pressure relief valve of the cleaning channel is independent and installed on the toilet lid, which makes the toilet lid thick and inconvenient; Since the outlet of the electromagnetic pilot valve of one of the electromagnetic pilot valve A and the electromagnetic pilot valve B is divided into flushing water flow and metering water flow, the metering water flow is connected with the water inlet of the flow sensor, so the two water flows share a flow sensor, which is beneficial to The overall water consumption is accurately measured, which is conducive to reasonable and water saving; since a metered water flow of a solenoid pilot valve and a branch passes through the flow sensor, the branched water flow can be set to a relatively small flow, and the cleaning water flow through the pressure reducing valve is also a relatively small flow. The flow sensor has the advantages of small flux, small volume and high measurement accuracy; the invention also has the characteristics of compact overall structure, small volume, low cost, convenient installation and use, and the like.

detailed description

Decompression and flushing integrated valve, see Figures 1 and 4, the valve body is provided with water inlet 2, water outlet A1, water outlet B3 and atmospheric communication chamber 10. The symmetrical ports on both sides of the water inlet channel of the valve body are respectively provided at corresponding positions There are solenoid pilot valve A4 and solenoid pilot valve B6. The interrupted part of the main water outlet channel A15 corresponding to the outlet 4-3 of the solenoid pilot valve A4 forms a valve seat-like structure, and a vacuum break valve core A9 is provided at the corresponding position of the valve seat-like structure. The main water outlet channel A15 is bent to the outside from the interrupted part and then turned back to communicate with the water outlet A3. A flow restrictor 8 is provided at the turn-back section of the main water outlet channel A15. The interrupted part of the main water outlet channel B14 corresponding to the outlet 6-2 of the solenoid pilot valve B6 forms a valve seat-like structure. The valve seat-like structure is provided with a vacuum breaking valve core B13 at the corresponding position, and the main water outlet channel B14 is folded outward from the interrupted portion The bend turns back and is connected to the outlet B1. The vacuum breaking valve core A9 corresponds to the atmospheric port A15-1 on the main water outlet channel A15, and the vacuum breaking valve core B13 corresponds to the atmospheric port B14-1 on the main water outlet channel B14, the atmospheric port A15-1, the atmospheric port B14-1 communicates with the atmosphere communication cavity 10.

A filter 5-3, a pressure reducing valve 5, and a flow sensor 7 are arranged in the axial extension section of the water inlet channel of the valve body in sequence. The pressure reducing valve 5 may be an electromagnetic direct-acting valve. The outlet direction of the flow sensor forms a cleaning channel 11, see Figure 2, 4, 5. The cleaning channel 11 is provided with an atmosphere communication port C11-3, the atmosphere communication port C is provided with a vacuum breaking valve core C12, the vacuum breaking valve core C12 is provided with a safety relief device 12-1, and the atmospheric port C11-3 is connected to the atmosphere The communication cavity 10 penetrates. The end of the vacuum breaking valve core B13 in the atmospheric direction and the end of the vacuum breaking valve core C12 in the atmospheric direction are pressed against each other by a compression spring. The cleaning channel 11 is provided with an overflow port 11-1 and a water outlet C11-2 passing through the overflow port. The other end of the vacuum break valve core C12 corresponds to the overflow port 11-1, see FIGS. 4 and 6. The atmosphere communication port A15-1, the atmosphere communication port B14-1, the atmosphere communication port C11-3 and the overflow port 11-1 are essentially like valve seats.

The pilot overflow channel 6-3 of the solenoid pilot valve B6 is connected to the water inlet 7-1 of the flow sensor 7, see Fig. 5. The solenoid pilot valve has a pilot valve seat with a small flux and a main valve seat with a large flux. The solenoid coil is energized, and the relatively small starting force causes the valve seat to open. The back pressure chamber corresponding to the main valve seat overflows through the pilot valve seat, the back pressure chamber is relieved, the main valve flap is lifted, and the main valve seat is opened. When overflowing, water enters the side hole of the main valve disc, flows through the back pressure chamber, and then flows out from the pilot valve seat. The present invention connects the pilot overflow channel 6-3 of the electromagnetic pilot valve B6 with the water inlet 7-1 of the flow sensor 7 so that the overflow water flows through the flow sensor 7. Since the solenoid pilot valve A and the solenoid pilot valve B are essentially the same, the replacement of the solenoid pilot valve A and the solenoid pilot valve B is the same.

The open state of solenoid pilot valve B6 corresponds to:

The vacuum break spool B13 is pushed to the atmosphere under the action of the water flow pressure, the main water outlet channel B14 of the electromagnetic pilot valve B6 is opened, and the atmosphere connection port B14-1 is closed; the vacuum break spool C12 is pushed by the vacuum break spool B13 and pushed Toward the flow port 11-1, the atmosphere communication port C11-3 is opened, and the flow port 11-1 is closed.

The pressure-reducing and flushing integrated valve is installed on the ceramic barrel of the smart toilet to realize toilet flushing and human body cleaning.

Body cleansing. Refer to Figures 1, 2, 5 and 6, the pressure reducing valve coil 5-1 is energized, the pressure reducing valve 5 is opened, and the water inlet 2 enters water, and then passes through the pressure reducing channel inlet 5-2, the filter 5-3 and the pressure reducing device in turn 5-4, flow through the flow sensor 7. The water flow in the cleaning channel 11 pushes the vacuum breaking valve core C12 to move to the atmosphere, closes the atmospheric communication port C11-3, opens the flow port 11-1, and the cleaning water flows out of the water outlet C11-2 after passing through the flow port 11-1. Cleaning the human body. The flow sensor 7 measures the flow of cleaning water.

For toilet flushing, the upper part of the ceramic bowl is flushed with the brush ring side and the lower part is flushed with the siphon side, see Figures 1, 4 and 5.

Flushing on the side of the brush circle is realized by flushing water line A. The coil A4-1 is energized, the solenoid pilot valve A4 is opened, the main valve including the diaphragm A4-2 is lifted (the main valve including the diaphragm A4-2 is in the closed state in Figure 3), and the corresponding main valve seat and water inlet are opened. 2 The inlet water flows into the main water outlet channel A15 through the main valve seat, pushing the vacuum breaking valve core A9 to move to the atmosphere, closing the atmospheric port A15-1, the water flow is bent and turned back, and flows out from the water outlet A3 to realize the flushing of the brush circle side.

The siphon side flushing is realized by flushing water line B. The coil B6-1 is energized, the electromagnetic pilot valve B6 is opened, and the water inlet 2 enters. At this time, the water flow is divided into two paths, one large and one small. The large water flow flows into the main water outlet channel B14 through the main valve seat, pushing the vacuum breaking valve core B13 to move to the atmosphere, closing the atmospheric port B14-1, the water flow is bent and turned back, and flows out from the water outlet B1 to achieve siphon side flushing. The small water flow flows in from the side hole of the main valve disc, flows out from the pilot valve seat to the pilot overflow channel 6-3 of the electromagnetic pilot valve B after passing through the back pressure chamber, and flows through the flow sensor 7 into the cleaning channel 11. After the above-mentioned vacuum breaking valve core B13 moves to the atmosphere, the vacuum breaking valve core C12 is pushed to the overflow port 11-1, the overflow port 11-1 is closed, and the atmospheric communication port C11-3 is opened, and the small water flow is not It will be injected into the outflow port 11-1, enter the atmosphere communication chamber 10 through the atmosphere communication port C11-3, and then flow out from the water outlet A3 after passing the atmosphere communication port A15-1. The small water flow passes through the flow sensor 7 to realize water flow measurement. The small water flow measurement is easy to convert to obtain the large water flow measurement of the water outlet B1. Due to the consistency of the electromagnetic pilot valve A and the electromagnetic pilot valve B, the water flow measurement of the flushing water path A is also easily obtained.

The present invention integrates the electromagnetic pilot valve A and electromagnetic pilot valve B for flushing and defecation of the smart toilet and the pressure reducing valve for cleaning the human body. The overall structure is compact, the volume is small, the installation is convenient, and the cost is low. A separate pressure reducing valve cleaning system is installed on the upper side, which can eliminate the drawbacks of heavy and inconvenient toilet lids caused by the installation of pressure reducing valves. In the present invention, a flow sensor is installed in the cleaning channel in the outlet direction of the pressure reducing valve. The pilot overflow channel of the electromagnetic pilot valve B is connected to the water inlet of the flow sensor. The two water flows share a flow sensor, which can measure the flow of the cleaning water path for cleaning the human body. The flow rate of the flushing water path B for flushing urine and feces can be obtained at the same time as the flow rate of the flushing water path A, and because the small pilot overflow flow rate of the solenoid pilot valve B and the relatively small flow rate of the cleaning water flow are directly measured, The flow sensor has small flux, small size, high measurement accuracy and low price. The structure of the present invention combined with the above description shows that the present invention can avoid the cascading of various water streams, that is, the cleaning water flowing through the pressure reducing valve does not enter the main water outlet channel A or the main water outlet channel B, the main water outlet channel A, the main water outlet channel B water flow, And the pilot overflow water of the metered solenoid pilot valve B (or solenoid pilot valve A) does not enter the cleaning channel, and the related reasons will not be repeated.
