Preferably, the vacuum interface is connected to a vacuum source for providing a vacuum environment.
Preferably, a sliding block 2 is arranged between the rubber sleeve 1 and the permanent magnet 3, and two ends of the sliding block 2 are respectively contacted with the rubber sleeve 1 and the permanent magnet 3.
Preferably, the permanent magnet 3 is formed with a through hole, and a fixing post is formed below the slider 2 and inserted into the through hole, and the through hole is matched with the valve rod 16.
Preferably, the water supply valve body 7 includes an inlet pipe formed on the inlet pipe and an outlet pipe formed on the outlet pipe.
Preferably, the lower part of the valve rod 16 is fixedly connected with the sealing gasket 14.
Preferably, a filter screen 6 is fixedly installed at the water inlet.
Preferably, the base 5 is fixedly connected with an end cover 10, the vacuum port is formed on the end cover 10, a throttle valve 12 and a one-way valve 13 are fixedly installed inside the end cover 10, the cavity is communicated with the one-way valve 13, the one-way valve 13 is communicated with the throttle valve 12, and the throttle valve 12 is communicated with the vacuum port. The screw 9 penetrates through the end cover 10 to be in threaded connection with the base 5 to fix the end cover 10 and the base 5.
Preferably, an O-ring seal 11 is provided between the end cap 10 and the base 5, the O-ring seal 11 sealing the end cap 10 and the base 5.
Preferably, a V-shaped sealing ring 8 is fixedly installed at the bottom of the base 5, and the valve rod 16 is slidably connected with the V-shaped sealing ring 8.
The working principle is as follows:
when the water supply valve is in a standby state, as shown in fig. 3, a cavity formed by the rubber sleeve 1 and the base 5 is filled with air under normal pressure, and the slide block 2 and the permanent magnet 3 are positioned at the topmost end under the action of the first spring 4. The lower end of the valve rod 16 is connected with the sealing pad 14, and is pressed tightly on the valve port of the water outlet pipe under the action of the second spring 15, so that the water supply valve body 7 is in a closed state.
When the water supply valve is in a working state, as shown in fig. 4, after the vacuum toilet system activates the flushing process, the controller provides vacuum to the water supply valve through the vacuum interface, so that air in a cavity formed by the rubber sleeve 1 and the base 5 is pumped away, and a vacuum environment is formed in the cavity. The rubber sleeve 1 pushes the sliding block 2 and the permanent magnet 3 to move towards the interior of the cavity against the acting force of the first spring 4 under the action of vacuum, the magnetic force of the permanent magnet 3 acting on the valve rod 16 is gradually increased along with the gradual approach of the permanent magnet 3 to the valve rod 16, and when the magnetic force is greater than the elastic force of the second spring 15, the valve rod 16 is lifted upwards, the valve port of the water supply valve body 7 is opened, and water is supplied to a toilet flushing ring or a flushing nozzle.
When the flushing process of the vacuum toilet system is finished, the controller stops providing vacuum to the water supply valve, the vacuum interface is connected to the outside atmosphere, and due to the throttling effect of the throttle valve 12, the vacuum in the cavity is slowly restored to the normal pressure state, so that the water supply valve cannot be closed immediately, a small amount of water flows into the toilet bowl, and a 'water seal' is formed at the bottom of the toilet bowl.
In the standby state, the check valve 13 is in contact with the seat 5. When the vacuum is switched on, the check valve 13 moves in the direction away from the base 5 due to the force generated by the air pressure difference between the two sides. Because the outer diameter of the one-way valve 13 is smaller than the inner diameter of the hole corresponding to the one-way valve on the base 5, air can be quickly pumped out from the gap between the flange part of the one-way valve 13 and the base 5 (meanwhile, the air can also be pumped out through the through hole in the middle of the one-way valve 13 and the throttle valve 12 in sequence); when the vacuum interface is communicated with the atmosphere, because the interior of the base 5 is still in a vacuum state, the check valve 13 is tightly attached to the base 5 to form a seal under the action of air pressure difference, and the vacuum can be slowly released only through a through hole in the middle of the check valve 13 through the throttling valve 12. Preferably, the one-way valve 13 is made of an elastic material.
It should be noted that the controller is communicated with the vacuum source, and the controller is used for switching the cavity to be communicated with the vacuum source or the external atmosphere. The controller may be a directional valve.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit the same; although the present application has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not necessarily depart from the spirit and scope of the corresponding technical solutions in the embodiments of the present application.
