Example two

The present embodiment provides a refill valve that can be used as an automatic refill assembly 40 for a fill valve in the first embodiment. Specifically, referring to fig. 4, the water replenishing valve includes a water replenishing valve body 41 and a solenoid valve assembly 42 provided to the water replenishing valve body 41; the water replenishing valve body 41 is arranged in the water replenishing accommodating cavity 102; the solenoid valve assembly 42 includes a solenoid valve 421 and a blocking piece 422 connected to the solenoid valve 421, and the solenoid valve 421 drives the blocking piece 422 to move, so that the blocking piece 422 selectively blocks the communication passage between the refill accommodating chamber 102 and the refill outlet 104. Namely, the electromagnetic valve 421 is electrically controlled to realize automatic water replenishing without manual operation.

Specifically, the solenoid valve 421 includes a magnet coil 4211, an elastic member 4212 and a moving iron valve core 4213, and the bottom end of the moving iron valve core 4213 is connected to the plugging member 422. The specific principle of the driving of the solenoid valve 421 can refer to the prior art, and is not the focus of the present application, which is not described herein again.

EXAMPLE III

In the water replenishing valve of the second embodiment, the plugging member 422 is directly driven by the electromagnetic valve 421, and the movement stroke of the plugging member 422 is long, so that the blocking phenomenon is easily caused, and the water replenishing failure is further caused; moreover, in the second embodiment, the elastic member 4212 in the electromagnetic valve 421 needs to overcome the water pressure in the accommodating cavity to stretch and retract, and then the blocking member 422 can be driven to move, so that the water replenishing valve needs to have a larger electromagnetic attraction force, and the water replenishing valve which can meet the requirement has a larger volume, and is difficult to be installed on the water inlet valve. Thus, the present embodiment provides an alternative refill valve that can also be used as the automatic refill assembly 40 for the fill valve of the first embodiment.

Referring to fig. 1 and 5, the water replenishing valve includes a water replenishing valve body 41 and a solenoid valve assembly 42 provided to the water replenishing valve body 41; the water replenishing valve body 41 is arranged in the water replenishing accommodating cavity 102; the water replenishing valve body 41 is provided with a first water replenishing channel 411 and a second water replenishing channel 412 which both extend along a first direction (namely, the direction X in the drawing), the first water replenishing channel 411 is provided with a first water inlet 4111 and a first water outlet 4112, the second water replenishing channel 412 is provided with a second water inlet 4121 and a second water outlet 4122, the first water inlet 4111 is communicated with the water replenishing accommodating cavity 102, the second water outlet 4122 is communicated with the water replenishing outlet 104, and the solenoid valve assembly 42 is selectively communicated with the first water outlet 4112 and the second water inlet 4121.

In specific implementation, when water needs to be replenished, the electromagnetic valve assembly 42 acts to communicate the first water outlet 4112 with the second water inlet 4121, water that has entered the water replenishing accommodating cavity 102 enters the first water replenishing channel 411 through the first water inlet 4111, and enters the second water replenishing channel 412 through the first water outlet 4112 and the second water inlet 4121 in sequence, and finally enters the water replenishing outlet 104 through the second water outlet 4122 to flow out. When water is not required to be supplemented, the solenoid valve assembly 42 is actuated to make the first water outlet 4112 and the second water inlet 4121 not communicated, so that water cannot flow into the second water supplementing channel 412 through the first water supplementing channel 411, and cannot flow to the water supplementing outlet 104, which is equivalent to blocking the communication channel between the water supplementing outlet 104 and the water supplementing accommodating cavity 102. Here, the electromagnetic valve assembly 42 is not directly plugged by the plugging piece 422, but the electromagnetic valve assembly 42 only cuts off the communication between the first water replenishing channel 411 and the second water replenishing channel 412 by the arrangement of the first water replenishing channel 411, the second water replenishing channel 412 and the corresponding water inlet and water outlet, so that the connection between the water replenishing accommodating cavity 102 and the water replenishing outlet 104 can be indirectly plugged, the possibility of shortening the movement stroke of the electromagnetic valve assembly 42 is provided, the electromagnetic suction force required by the water replenishing valve is reduced, and the model selection volume of the water replenishing valve can be as small as possible; meanwhile, the automatic water replenishing operation is more reliable and smooth, and the phenomenon of blocking is not easy to occur.

With continued reference to fig. 5, the water replenishing valve body 41 is provided with a valve chamber 413, the first water outlet 4112 and the second water inlet 4121 are communicated through the valve chamber 413, and the solenoid valve assembly 42 is provided in the valve chamber 413 and selectively communicates with a communication passage between the first water outlet 4112 and the second water inlet 4121. More specifically, a valve seat 414 is provided in the valve chamber 413; the second water replenishing passage 412 extends upward to the top end of the valve seat 414, and a passage is formed between the inner wall of the valve chamber 413 and the outer wall of the valve seat 414, and this passage can be used as the first water replenishing passage 411, so that the first water outlet 4112 and the second water inlet 4121 are directly communicated through the valve chamber 413.

In one embodiment, the solenoid valve assembly 42 includes a solenoid valve 421 and a closure member 422. The moving iron valve core 4213 of the solenoid valve 421 connects the blocking piece 422, and the blocking piece 422 is driven by the moving iron valve core 4213 to move so as to block the second water inlet 4121 or the first water outlet 4112, so long as the communication between the first water inlet 4111 and the first water outlet 4112 can be cut off. The plugging member 422 is similar to the plugging manner of the plugging member 422 in the second embodiment, and the description thereof is omitted.

In another embodiment, a diaphragm 415 and a valve core cap 416 are disposed in the valve chamber 413, the diaphragm 415 divides the valve chamber 413 into an upper back pressure chamber 4131 and a lower valve chamber 4132, and the valve core cap 416 is disposed at the bottom end of the moving iron valve core 4213. The diaphragm member 415 is provided with side holes and a center hole.

When the water replenishing valve is in a closed state, namely when the water replenishing valve is not electrified, the moving iron valve core 4213 tightly abuts against the diaphragm piece 415, the diaphragm piece 415 abuts against the top of the valve seat 414, the second water inlet 4121 is further blocked, the valve core cap 416 abuts against a central hole in the diaphragm piece 415, and the valve core cap 416 plays a role in blocking the central hole, so that the back pressure chamber 4131 and the second water replenishing channel 412 cannot be communicated through the central hole.

When water is required to be supplemented: the magnet coil 4211 is electrified, the moving iron valve core 4213 drives the valve core cap 416 to move upwards, the valve core cap 416 is separated from the central hole, and water in the back pressure chamber 4131 flows into the second water replenishing channel 412 from the central hole; water enters the back pressure chamber 4131 from the first water replenishing channel 411 through the side hole, the aperture of the central hole is larger than that of the side hole, therefore, the water inlet speed in the back pressure chamber 4131 is smaller than the water outlet speed, negative pressure is generated in the back pressure chamber 4131, the upper side and the lower side of the diaphragm member 415 are stressed differently, the diaphragm member 415 presses the back pressure chamber 4131, the diaphragm member 415 is not abutted against the valve seat 414, and the second water inlet 4121 and the first water outlet 4112 are directly communicated through the valve cavity 413.

When the water replenishing is stopped: when the magnet coil 4211 is powered off, the moving iron spool 4213 moves downwards under the action of the elastic member 4212, the central hole is blocked by the spool cap 416 again, so that water in the back pressure chamber 4131 cannot flow out of the central hole, but water continuously enters the back pressure chamber 4131 through a side hole, the water pressure of the back pressure chamber 4131 rises rapidly, the upper side and the lower side of the diaphragm member 415 are stressed differently, at the moment, the diaphragm member 415 presses the valve chamber 4132 and abuts against the valve seat 414 again, the communication between the second water inlet 4121 and the first water outlet 4112 is cut off again, and the water flow from the first water replenishing channel 411 to the second water replenishing channel 412 is prevented.

Alternatively, one of the first and second water replenishing passages 411 and 412 may be provided around the periphery of the other. In this embodiment, the central hole is located at the center of the diaphragm 415, and the side holes are located at the sides deviating from the center of the diaphragm 415, so that the first water replenishing channel 411 is disposed around the second water replenishing channel 412 to match the arrangement of the central hole and the side holes.

Referring to fig. 7 and 8, the water replenishing valve body 41 includes a first body 417 and a second body 418 arranged in sequence along a first direction, and a projection area of the first body 417 on a plane perpendicular to the first direction is larger than that of the second body 418; referring to fig. 5, the solenoid valve assembly 42 and the first water replenishing passage 411 are provided on the first body 417, and the second water replenishing passage 412 is provided on both the first body 417 and the second body 418. The overall dimension of the water replenishing valve body 41 of the whole water replenishing valve is sequentially reduced along the first direction, so that the material is saved, the weight of the whole water replenishing valve is reduced, the water replenishing valve body is convenient to be matched with a water inlet valve, the water replenishing valve body 41 of the water replenishing valve can extend into the water inlet valve as much as possible to be arranged, and the occupation of the water inlet valve on the installation space is reduced.

When the water replenishing valve is implemented specifically, the water replenishing valve is arranged above the water inlet valve, and the first direction is parallel to the vertical direction. The water replenishing valve is used for automatically replenishing water, and manual operation is not needed, so that the water replenishing valve is arranged above the water inlet valve, and the installation space below the water inlet valve can be saved. For example, referring to fig. 5, the opening of the first water inlet 4111 may be directed vertically downward, that is, the first water inlet 4111 is opened at the free end of the first water replenishing channel 411 in the first direction; referring to fig. 6 again, in another embodiment, the opening of the first water inlet 4111 may also be oriented horizontally, that is, the first opening 4111 is opened on a circumferential side wall of the first water replenishing passage 411. During specific implementation, how to arrange water inlet to determine the specific opening position of the first water inlet 4111 after the water replenishing valve is assembled on the water inlet valve, if water is more conveniently fed from the side, the first water inlet 4111 is opened at the side of the water replenishing valve body 41, and if water is more conveniently fed from the end, the first water inlet 4111 is arranged at the bottom end of the water replenishing valve body 41.

Further, with reference to fig. 5, the first water replenishing passage 411 is disposed around the second water replenishing passage 412, so that the first water inlet 4111 is disposed on the end surface of the end of the first body 417 connected to the second body 418. In one embodiment, referring to fig. 8, a first water inlet 4111 is formed on the first body 417 and has a downward opening. In another embodiment, referring to fig. 9, a plurality of filter holes 4171 are provided on an end surface of one end of the first body 417 connected to the second body 418, the filter holes 4171 are communicated with the first water replenishing channel 411, and each filter hole 4171 can be used as the first water inlet 4111; here, the filtration hole 4171 can be set small enough, can also filter impurity such as aquatic silt when accomplishing the function of intaking, effectively avoids impurity to get into inside the moisturizing valve, causes the card to die.
