Simple structure and no need of auxiliary reset control system.

Preferably, the driving motor 410 is a motor without a gear box, because the gear box has a certain self-locking force, and the elastic member 480 has a certain difficulty in overcoming the self-locking force.

In this embodiment, the elastic member 480 is a spring.

Referring to fig. 3 to 5, preferably, the water level sensing structure 500 includes a reed pipe 510 and a magnetic ring 520 sleeved with the reed pipe 510, the magnetic ring 520 is disposed in the accommodating space 10 between the water tank 100 and the base 200 and is displaced along with the change of the water level in the accommodating space 10 to trigger the reed pipe 510 to send a corresponding water level signal to the driving motor 410, and the reed pipe 510 is fixed in the accommodating cavity 20 formed by the upper side wall of the base 200 protruding upward.

In the present embodiment, the accommodating space 10 is an atomizing chamber.

In the present embodiment, the reed switch 510 is in signal connection with the main control circuit board 460. The abutting structure 450 moves upward to open the lower water valve structure 300 under the driving of the driving motor 410, so that the water in the water tank 100 can flow down from the gap between the lower water valve structure 300 and the lower water hole 101 to reach the accommodating space 10. When the water level of the accommodating space 10 rises, the magnetic ring 520 also rises along with the rise of the water level, when the reed pipe 510 detects the magnetic force of the magnetic ring 520, the main control circuit board 460 (the reed board and the main control circuit board 460 can be connected through a cable or a direct board to realize signal transmission) sends a signal to the driving motor 410, the motor rotates reversely, and the sewer valve structure 300 closes the sewer hole 101 to stop water supplement.

In the present embodiment, the elastic body 330 is a spring.

Referring to fig. 3 to 5, the working process of the water valve control mechanism is as follows:

when the accommodating space 10 of the humidifier 1 is in a water shortage state, after the magnetic ring 520 sinks, the reed pipe 510 fails to detect magnetic force, the main control circuit board 460 receives a signal of the reed pipe 510, then the main control circuit board 460 sends a water replenishing instruction to the driving motor 410, at this time, the driving motor 410 operates according to a preset direction, the output shaft and the driving wheel 420 rotate together, the synchronous belt 440 also transmits together, the synchronous belt 440 drives the ejector rod 453 to move upwards through the fixing portion 451, so that the top portion 452 pushes the elastic sealing sleeve 470, the elastic sealing sleeve 470 pushes the lower end of the valve shaft 320, the valve shaft 320 compresses the elastic body 330 and drives the sealing body 310 to move upwards, and the water drain valve structure 300 is opened.

When the lift pin 453 reaches the upper limit, the lift pin 453 cannot move upwards, at this time, the driving motor 410 receives an obvious resistance, the current is increased instantly, and the main control circuit board 460 issues an instruction, so that the driving motor 410 stops operating and keeps a static moment. The drain valve structure 300 is always in an open state and the water tank 100 is always in a state of adding water to the accommodating space 10.

Along with the rising of the water level of the accommodating space 10, the magnetic ring 520 moves upwards along with the rising of the water level, when the magnetic ring 520 reaches a certain height, the reed switch 510 detects a magnetic signal, the main control circuit board 460 sends an instruction to the driving motor 410 to rotate reversely, and the push rod 453 is driven to slide downwards to the lower limit through the synchronous belt 440. The mandril 453 is separated from the elastic sealing sleeve 470, and under the action of elastic restoring force, the valve shaft 320320 and the elastic sealing sleeve 470 both move downwards to drive the sealing body 310 to close the drain hole 101, so that the drain valve structure 300 is closed. So that the water tank 100 stops replenishing the accommodating space 10 with water.

There is a special case that the driving motor 410 is suddenly cut off to stop working without generating a rotational moment when the water tank 100 supplies water to the accommodating space 10, and at this time, the elastic member 480 acts to push down the push rod 453 to a lower limit position to drive the driving motor 410 to reset. The risk that the drain valve structure 300 cannot be closed due to the fact that the drive motor 410 cannot be reset in time after being powered off is solved. No complex power-off protection device is required, and no potential safety hazard that the drain valve structure 300 cannot be closed exists. If the drain valve structure 300 cannot be closed in time, water will continue to flow down, causing the humidifier 1 to overflow, and possibly enter the base 200 to burn the driving motor 410.

The water valve control mechanism has the advantage that the noise of the transmission of the synchronous belt 440 is low, and the high noise of the gear transmission is avoided.

Besides the reed switch 510 and the magnetic ring 520, the system for detecting the water level can also be other water detection devices, such as a spring water detection device and the like.

In this embodiment, by applying the water valve control mechanism to the humidifier 1, the water replenishing signal and the water full signal can be quickly responded, the triggering speed is high, and the water replenishing can be timely controlled. Meanwhile, the structure is compact, the occupied space is small, the overall size of the humidifier 1 can be effectively reduced, and the use experience of a user on the humidifier is improved.

5. The water valve control mechanism of claim 4, wherein the mounting seat further comprises a first collar formed by upwardly projecting from the top of the main seat body, the first collar enclosing the mounting hole, and a top surface of the first collar and the inner wall of the base together clamp the sealing ring.

6. The water valve control mechanism of claim 5, wherein the mounting seat further comprises a second collar formed by protruding from the top of the main seat body, the second collar is disposed around the outer circumference of the first collar, and the top of the second collar abuts against the inner wall of the base.

7. The water valve control mechanism as claimed in claim 3, wherein the water valve control device further comprises an elastic member, the elastic member is sleeved on the push rod and located in the cavity, an upper end of the elastic member abuts against an upper cavity wall of the cavity, and a lower end of the elastic member abuts against the push rod.

8. The water valve control mechanism as claimed in any one of claims 1 to 7, wherein the water level sensing structure includes a reed switch and a magnetic ring sleeved with the reed switch, the magnetic ring is disposed in the accommodating space between the water tank and the base and is displaced along with the change of the water level in the accommodating space so as to trigger the reed switch to send a corresponding water level signal to the driving motor, and the reed switch is fixed in an accommodating cavity formed by an upper side wall of the base and protruding upwards.

9. The water valve control mechanism according to any one of claims 1 to 7, wherein the drain valve structure includes a sealing body, a valve shaft, and an elastic body, an upper end portion of the valve shaft extends from the drain hole into the tank, the sealing body is connected to an upper end portion of the valve shaft, a lower surface of the sealing body is in sealing contact with a hole edge of the drain hole, and the elastic body is elastically compressed between a lower end portion of the tank and a lower end portion of the valve shaft.

10. A humidifier comprising a water tank and a base, said water tank being disposed above said base, wherein said humidifier further comprises a water valve control mechanism as claimed in any one of claims 1 to 9.
