Referring to fig. 1 to 2, a water level control apparatus 100 according to an embodiment of the present invention can be applied to a water purifying apparatus, such as a pump-free electroless reverse osmosis water purifier. The water level control apparatus 100 includes a tank 10, a valve body assembly 20, and a guide sealing member 40 having magnetism.

A float assembly 12 is disposed within the tank 10. The float assembly 12 is capable of floating up and down under the buoyancy of the water. The floating assembly 12 includes a floating member 121 and a magnetic member 122 connected to the floating member 121. In the example of fig. 1 and 2, the tank 10 has a water receiving opening 101. External water (e.g., pure water from a water purifier) may be introduced into the tank 10 through the water receiving port 101. When the water level in the tank 10 rises, the floating member 121 can float up under the buoyancy of the water in the tank 10 and drive the magnetic member 122 to move upward (as shown in fig. 2). When the water level in the tank 10 drops, the floating member 121 drops and drives the magnetic member 122 to move downward (as shown in fig. 1) as the water level in the tank 10 drops. The shape and structure of the floating member 121 may be set according to specific circumstances, and is not limited to the hollow structure shown in fig. 1 and 2. The magnetic member 122 is, for example, a permanent magnet. In addition, water in the tank 10 can also flow out of the tank through the water receiving opening 101, that is, the water receiving opening 101 can be used as a water inlet or a water outlet.

The valve body assembly 20 includes a valve body 21 and a valve sheet 22. The valve body 21 is provided with a valve cavity 211. The valve plate 22 is disposed in the valve cavity 211. The valve body 21 is provided with a water inlet 212, a water outlet 213, a channel port 214, a pressure relief hole 215 and a pressurization hole 216. The pressurizing hole 216 communicates the valve cavity 211 and the water inlet 212. The water outlet 213 is communicated with a pressure relief hole 215. The passage port 214 can connect or disconnect the water inlet 212 and the water outlet 213. The floating member 121 can bring the magnetic member 122 away from or close to the guide seal 40 in case the water level in the tank 10 rises or falls. When the magnetic member 122 is far from the guide seal 40, the guide seal 40 can move downward and block the pressure relief hole 215, so that the valve plate 22 can block the passage port 214 to disconnect the water inlet 212 and the water outlet 213 under the action of the water pressure in the valve cavity 211. In the case that the magnetic member 122 is close to the guide sealing member 40, the guide sealing member 40 can move upward by the attraction force of the magnetic member 122, so that the passage port 214 communicates with the water inlet 212 and the water outlet 213.

In the present embodiment, the water level control apparatus 100 includes an elastic member 30. The elastic member 30 elastically abuts against the guide seal member 40. The guide seal 40 is located between the elastic member 30 and the valve sheet 22. In the case that the magnetic member 122 is far from the guide sealing member 40, the guide sealing member 40 can move downward and block the pressure relief hole 215 by the elastic force of the elastic member 30, and in the case that the magnetic member 122 is close to the guide sealing member 40, the guide sealing member 40 can press the elastic member 30 and move upward by the attraction force of the magnetic member 122.

Specifically, when the water level in the tank 10 rises, the floating member 121 can float up under the buoyancy of the water in the tank 10 and drive the magnetic member 122 to move upward to be away from the guide sealing member 40 (as shown in fig. 2), and can move until the attraction force between the magnetic member 122 and the guide sealing member 40 is lost, so that the guide sealing member 40, which is not attracted by the magnetic member 122, can move downward under the elastic force of the elastic member 30 and block the pressure relief hole 215. Meanwhile, water entering from the water inlet 212 can enter the valve cavity 211 through the pressurizing hole 216, so that the pressure area of the upper surface of the valve plate 22 is larger than that of the lower surface of the valve plate 22, and then the valve plate 22 tightly presses the channel port 214 under the action of water pressure to disconnect the water inlet 212 and the water outlet 213, and at this time, the water level control device 100 is equivalently in a disconnected state. When the water level in the tank 10 drops, the floating member 121 drops along with the drop of the water level in the tank 10 and drives the magnetic member 122 to move downward to be close to the guiding sealing member 40 (as shown in fig. 1), the guiding sealing member 40 can move upward against the pressure of the elastic member 30 under the action of the suction force of the magnetic member 122, at this time, the valve cavity 211 can be communicated with the water outlet 213 through the pressure relief hole 215, so that the valve plate 22 opens the passage port 214 under the action of the pressure of the inlet water to communicate the water inlet 212 with the water outlet 213, and at this time, the water level control device 100 is equivalently in an open state. In turn, the water level control apparatus 100 can mechanically realize automatic control of opening and closing of the water path.

In conclusion, the guiding sealing element 40 can effectively block the pressure relief hole 215, and the valve plate 22 can effectively block the passage port 214, so that the reliability of water closing of the valve body 21 when the water pressure is low can be improved, and then water resources are not easily wasted. In addition, the water level control device 100 can normally work without being electrified, has a simple structure, is reliable and durable, and can control the buoyancy required by closing the water channel of the water level control device 100 not to be influenced by the municipal water supply pressure, so that noise is not generated in the normal water passing process, and the user experience can be improved.

It is understood that the relief hole 215 may be made larger than the pressure-increasing hole 216 in order to improve the reliability of the valve sheet 22 in opening or closing the passage port 214. Of course, the shapes of the pressure relief hole 215 and the pressure increasing hole 216 may be set according to the circumstances, for example, they may be set to be circular or elliptical.

In some embodiments, the water level control apparatus 100 includes a guide structure 50. The guide structure 50 connects the case 10 and the valve body 21. The guide structure 50 extends at least partially into the housing 10. The elastic member 30 is disposed in the guide structure 50. The pilot seal 40 is at least partially disposed within the pilot structure 50. In the present embodiment, the elastic member 30 is a spring, one end of the elastic member 30 is fixed in the guide structure 50, and the other end of the elastic member 30 elastically abuts against the guide seal 40. The guide structure 50 has a guide function guide structure for guiding the movement of the sealing member 40.

In some embodiments, the guiding structure 50 includes a guide sleeve 51 and a fixing portion 52. The guide sleeve 51 extends at least partially into the housing 10. The elastic member 30 is disposed in the guide bush 51. The fixing portion 52 is fixed in the valve cavity 211. In the present embodiment, the fixing portion 52 is fitted into the valve chamber 211 to fix the position of the guide structure 50. The guide sleeve 51 is substantially cylindrical. The elastic member 30 is fixed in the guide bush 51. The guide sleeve 51 guides the movement of the guide seal 40.

In some embodiments, the float member 121 is formed with a guide slot 123. The guide structure 50 extends at least partially into the guide slot 123. The magnetic member 122 surrounds the guide groove 123. In this embodiment, the floating member 121 is sleeved on the guide structure 50. The magnetic member 122 is fixed to the float member 121. In the present embodiment, the guide sleeve 51 extends at least partially into the guide groove 123. The provision of the guide groove 123 improves the stability of the movement of the float assembly 12, since the position of the guide structure 50 is fixed.

In certain embodiments, the pilot seal 40 includes a pilot portion 41 and a seal portion 42. The guide portion 41 is connected to the seal portion 42. The guide portion 41 abuts against the elastic member 30. In a case where the magnetic member 122 is away from the guide seal 40, the sealing portion 42 blocks the relief hole 215. In the present embodiment, the guide portion 41 has a substantially cylindrical shape, and the size of the seal portion 42 is smaller than that of the guide portion 41.

In certain embodiments, the seal 42 is T-shaped. Thus, the sealing effect of the sealing portion 42 is better.

It is understood that the sealing portion 42 may be made elastic in order to improve the sealing effect of the guide seal 40. In one example, the seal portion 42 is made of a rubber material.
