As shown in fig. 1, the first solenoid valve head 2 includes a fixing support 21, a coil 22, a movable iron core (not shown in the figure) and a return spring (not shown in the figure), the coil 22 is fixed outside the waterway distribution module 9 through the fixing support 21, the movable iron core is movably disposed in the coil 22, a plug 23 for opening and closing the first pressure relief hole 173 is disposed at one end of the movable iron core, and the return spring is sleeved outside the movable iron core and is used for returning the movable iron core. When the coil 22 is energized, the movable iron core is moved away from the first pressure relief 173 hole by the action of the magnetic field against the elastic force of the return spring, so that the plug 23 opens the first pressure relief 173 hole; when the coil 22 is powered off, the plunger is moved toward the first pressure release hole 173 by the restoring force of the return spring, so that the plug 23 closes the first pressure release hole 173. The structure and the working principle of the second solenoid valve head 3 are consistent or basically consistent with those of the first solenoid valve head 2, and are not described again. Because the power consumption of the coils of the first electromagnetic valve head 2 and the second electromagnetic valve head 3 is low, and the coils can work with small current, the first electromagnetic valve head 2 and the second electromagnetic valve head 3 can be powered by a super capacitor and/or a standby battery.
In this embodiment, as shown in fig. 5, the waterway distribution module 9 is further provided with an atmosphere port 112 communicated with the distribution chamber, and the atmosphere port 112 is controlled to open and close by an anti-siphon float 8 disposed in the distribution chamber 15. The outlet of the first waterway 16 is opposite to the anti-siphon float 8, so that when water flows out of the outlet of the first waterway 16, the anti-siphon float 8 is rapidly pushed to move upwards to close the atmospheric port 112. Two water-stop gaskets 81 are sleeved at the lower end of the anti-siphon floater 8. The air port 112 and the anti-siphon float 8 are arranged, so that when the mixing distribution valve is applied to a toilet flushing system, water in a toilet water tank can be prevented from being sucked into a tap water pipeline reversely when the tap water pipeline connected with the second water inlet channel 114 is in negative pressure. In other embodiments, the present invention does not provide the atmospheric port and the anti-siphon float, but realizes anti-siphon using an anti-siphon device installed between the second water inlet pipe and the tap water pipe or on the tap water pipe.
In this embodiment, the first water inlet channel 11 is provided with a one-way valve 7 which only allows water to flow from the first water inlet channel 11 into the distribution chamber 15. Specifically, the check valve 7 is located at the outlet of the first water inlet passage 11, but is not limited thereto. In this way, when the first waterway 16 is filled, the water can be prevented from flowing into the first water inlet passage 11 from the distribution chamber 15. Since the on-off between the first water path 16 and the second water inlet channel 14 is controlled by the second switching mechanism (i.e. the second electromagnetic valve head 6), a one-way valve is not required to be arranged on the first water path 16.
In this embodiment, the hydraulic water inlet module 10 is further provided with a second water outlet channel 113 and a second water channel 114, and the second water outlet channel 113 is communicated with the second water inlet channel 14 through the second water channel 114.
In this embodiment, the number of the first water outlet channels 12 and 13 is two, but not limited to this.
In this embodiment, as shown in fig. 1, the water path distribution module 9 is specifically assembled by a main valve body 91, an anti-siphon lid 92, a valve lid 93, and the like, the atmosphere port 112 is provided in the anti-siphon lid 12, and the anti-siphon lid 12 and the main valve body 11 are fitted with a seal ring 94. The hydraulic water inlet module 10 is approximately in an inverted Y shape.
The mixing and distributing valve of the invention can be applied to a toilet flushing system, as shown in fig. 10, the toilet flushing system comprises a water tank 20, a water pump 20 and a water inlet mechanism for replenishing water to the water tank 20, wherein the water inlet end of the water pump 30 is communicated with the water tank 20, when the mixing and distributing valve is applied, the first water inlet channel 11 is communicated with the water outlet end of the water pump 30, the second water inlet channel 14 is connected with a pressure water source, one first water outlet channel 12 is communicated with a washing ring part of a toilet body, and the other first water outlet channel 13 is communicated with a spraying part of the toilet body.
When the mixing distribution valve is matched with a water pump to be used for flushing a closestool and the water pump cannot work due to factors such as power failure, the mixing distribution valve can be connected with a pressure water source (namely a tap water pipeline) through the second water inlet channel 14, and the closestool is flushed by tap water supplied with water, so that the problem that the closestool cannot be normally used due to the fact that the water pump cannot work is solved. The invention also facilitates users to realize the switching use of water pump pressurization and tap water supply according to the water pressure of tap water under the condition of non-power-off, thereby achieving the purposes of saving energy and meeting the flushing requirements. The design of the mixing distribution valve of the invention also ensures that the closestool flushing system does not need to introduce an additional water inlet valve group, thereby ensuring that the integral structure of the closestool flushing system is simpler and the cost is lower. Particularly, when the first driving part and the second driving part adopt mechanical driving mechanisms or adopt electric control type driving mechanisms which are low in power consumption and can be driven by small current (for example, the first electromagnetic valve head 2 and the second electromagnetic valve head 3 can be directly supplied with power by super capacitors or batteries), the invention can still normally work under the condition that the water pump cannot work due to power failure, thereby ensuring that the closestool can still be normally flushed after power failure.
In the initial state of the mixing and dispensing valve of the present invention, as shown in fig. 3, the first communication port 19 is closed and the second communication port 110 is opened, so that one of the first discharge passages 12 corresponding to the second communication port 110 is opened and the other first discharge passage 13 corresponding to the first communication port 19 is closed. The mixing and dispensing valve of the present invention has two modes of operation, which are described below in connection with the flushing process of a toilet.
The first mode of operation of the invention is as follows:
in the pressurization mode of the water pump 30, when the water pump 30 is started, the water pump 30 pumps out the water in the water tank 20, the water enters the first water inlet channel 11, the water pressure pushes the check valve 7 to open, the water enters the distribution chamber 15, and pushes the anti-siphon float 8 to move upwards to close the air port 112, as shown in fig. 5; before the coil 22 of the first solenoid valve head 2 is electrified, the one first water outlet passage 12 is communicated with the distribution chamber 15, so that water flows to the one first water outlet passage 12 from the distribution chamber 15, the first valve chamber 171 and the second communication port 110 in sequence and finally flows out of the one first water outlet passage 12 (as shown in fig. 6), thereby flushing the pan surface of the toilet;
when the preset water outlet time of one of the first water outlet channels 12 is reached, the toilet finishes pan surface flushing, the coil 22 of the first electromagnetic valve head 2 is energized, so that the plug 23 opens the first pressure relief hole 173, therefore, the water in the first back pressure chamber 172 flows out through the first pressure relief hole 173, so that the water pressure of the first back pressure chamber 172 is greatly reduced, at this time, the water pressure in the first valve chamber 171 is much higher than the water pressure of the first back pressure chamber 172, therefore, the first switching member 5 moves towards the first back pressure chamber 172 under the push of the water pressure in the first valve chamber 171, so as to open the first communication port 19, and the water flows out from the other first water outlet channel 13, as shown in fig. 7, so as to flush away the dirt at the bottom of the toilet bowl. At the same time, the gasket 53 closes the second communication port 110, so that water does not flow out from the one of the first water outlet passages 12. When the coil 22 of the first solenoid valve head 2 is powered off or reverse current is supplied, the plug 23 of the first solenoid valve head closes the first pressure relief opening 173, at this time, water in the first valve chamber 171 is gradually supplemented into the first back pressure chamber 172 from the fine hole on the water stop diaphragm 52, so that the water pressure in the first back pressure chamber 172 is gradually increased until the water pressure is equal to the water pressure of the first valve chamber 171, at this time, because the cross-sectional area of the first back pressure chamber 172 is relatively large, the first switching member 5 is driven by the water pressure of the first back pressure chamber 172 and the first elastic member 4 to move in a direction away from the first back pressure chamber 172, so that the second communication opening 110 is opened, the first communication opening 19 is closed, the first switching member 5 is restored to the state shown in fig. 3, and the water pump 30 also stops working.
The second mode of operation of the invention is as follows:
in the running water supply mode, water enters the second water inlet channel 14, when the coil of the second solenoid valve head 3 is energized, the plug 31 of the second solenoid valve head 3 opens the second pressure relief hole 183, so that water in the second back pressure chamber 182 flows out through the second pressure relief hole 183, and the water pressure in the second back pressure chamber 182 is greatly reduced, at this time, the water pressure in the second valve chamber 181 is much higher than the water pressure in the second back pressure chamber 182, so that the second switching member 6 moves in the direction of the second back pressure chamber 182 under the pushing of the water pressure in the second valve chamber 181, and opens the third communication port 111, so that water flows to the first water channel 16 from the second valve chamber 181 and the third communication port 111 in sequence, as shown in fig. 8 and 9. When water is output from the first waterway 16, the water flow pushes the anti-siphon float 8 upwards, so that the anti-siphon float 8 moves upwards to close the atmospheric opening 112, meanwhile, the water flow pushes the check valve 7, so that the check valve 7 closes the first water inlet channel 11, and the water flows to the one of the first water outlet channels 12 from the distribution cavity 15, the first valve cavity 171 and the second communication port 110 in sequence, and finally flows out from the one of the first water outlet channels 12, as shown in fig. 6, so as to flush the pan surface of the toilet. Since the second water outlet channel 113 is communicated with the second water inlet channel 14, when water enters the second water inlet channel 14, the second water outlet channel 113 also outputs water to supply water to other components needing water.
When the preset water outlet time of one of the first water outlet channels 12 is reached, the toilet completes pan surface flushing, the coil 22 of the first electromagnetic valve head 2 is electrified, so that the plug 23 opens the first pressure relief hole 173, therefore, the water in the first back pressure chamber 172 flows out through the first pressure relief hole 173, so that the water pressure of the first back pressure chamber 172 is greatly reduced, at this time, the water pressure in the first valve chamber 171 is much higher than the water pressure of the first back pressure chamber 172, therefore, the first switching member 5 moves towards the first back pressure chamber 172 under the pushing of the water pressure in the first valve chamber 171, so as to open the first communication port 19, and the water flows out from the other first water outlet channel 13, as shown in fig. 7, so as to flush away the dirt at the bottom of the toilet bowl. At the same time, the gasket 53 closes the second communication port 110, so that water does not flow out from the one first water outlet channel 12. When the coil 22 of the first solenoid valve head 2 is powered off or reverse current is supplied, the plug 53 of the first solenoid valve head closes the first pressure relief opening 173, at this time, water in the first valve chamber 171 is gradually supplemented into the first back pressure chamber 172 from the fine hole on the water stop diaphragm 52, so that the water pressure in the first back pressure chamber 172 is gradually increased until the water pressure is equal to the water pressure of the first valve chamber 171, at this time, because the cross-sectional area of the first back pressure chamber 172 is relatively large, the first switching member 5 is moved and reset in a direction away from the first back pressure chamber 172 under the water pressure of the first back pressure chamber 172 and the pushing of the first elastic member 7, so that the second communication opening 110 is opened, the first communication opening 19 is closed, the first switching member 5 is restored to the state shown in fig. 3, and the water pump 30 also stops working. Similarly, when the coil of the second solenoid valve head 3 is powered off or reverse current is supplied, the plug 31 of the second solenoid valve head 3 closes the second pressure relief opening 183, at this time, water in the second valve cavity 181 is gradually supplemented into the second back pressure cavity 182 from the fine hole on the water stop diaphragm 61, so that the water pressure in the second back pressure cavity 182 is gradually increased until the water pressure is equal to the water pressure in the second valve cavity 181, at this time, because the cross-sectional area of the second back pressure cavity 182 is relatively large, the middle part of the second switching part 6 moves and resets in the direction away from the second back pressure cavity 182 under the pushing of the water pressure in the second back pressure cavity 182 and the second elastic member 41, so that the third communication opening 111 is closed, and the second water inlet channel 14 is disconnected from the first water channel 16.
