[0010] A water level control device according to the present application has the following technical effects:

[0011] (1) When water enters through the water inlet pipe and reaches a certain water level, the rotating shaft end of the floating plate drops, causing the floating plate and the supporting end of the connecting piece to break contact. At this time, the connecting piece drives the sealing body to block the water inlet pipe and cut off the water inlet; when the water level drops, the rotating shaft end of the floating plate rises, driving the sealing body to move up and break away from the fixing piece, and the water inlet pipe is opened, thereby achieving the purpose of automatic water level control;

[0020] In order to make the purpose, technical solution and advantages of the present application more clear, the embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other arbitrarily without conflict.

[0021] According to a water level control device of the present application, Figure 1-6 As shown, it includes a water storage box 10, a floating plate 20 and a sealing assembly 8. The floating plate 20 is arranged in the water storage box 10, and the sealing assembly 8 is arranged on the top of the water storage box 10. The water storage box is provided with a water inlet 9. Figure 1 The water inlet 9 shown in the figure is arranged at the top of the water storage box. A rotating shaft assembly for mounting the floating plate 20 is arranged at the water inlet 9. Figure 1 As shown, the shaft assembly can be formed on the top of the water storage box, including a shaft mounting portion 13 and a floating plate fixing member 12. The shaft mounting portion 13 can be integrally formed with the top, a screw mounting portion 132 is formed on the shaft mounting portion 13, and a screw mounting hole 122 is formed on the floating plate fixing member 12, and the shaft mounting portion 13 and the floating plate fixing member 12 can be assembled and fixed by screws.

[0022] like Figure 1-4As shown, a protrusion 131 is also provided on the shaft mounting portion 13, and a recess 121 is provided on the floating plate fixing member 12. The protrusion 131 is inserted into the recess 121, and the two are assembled to form a shaft hole 11. A shaft 21 is provided on the floating plate 20, and the shaft 21 is installed in the shaft hole 11. The floating plate 20 can rotate along the shaft 21 depending on the water level. The floating plate is provided with a protrusion structure 22 near the shaft 21, and the protrusion structure 22 will descend as the far end of the floating plate rises, and rise as the far end of the floating plate descends. In the present application, the protrusion on the shaft mounting portion and the recess on the floating plate fixing member are assembled to form a shaft hole, so that there is no need to open a shaft hole separately at other positions, avoiding additional processing steps and strength damage to the device components. Those skilled in the art can understand that the distal end mentioned in the present application is relative to the shaft end being regarded as the proximal end, and refers to the right side of the floating plate in the accompanying drawings.

[0023] The sealing assembly 8 is arranged at the water inlet 9, and the sealing assembly 8 includes a water inlet pipeline 1, a connector 3 and a sealing body 2. The connector 3 is arranged in the water inlet pipeline 1, preferably at the lower part of the water inlet pipeline 1. A fixing member 5 is arranged inside the water inlet pipeline 1, and a hole is arranged in the center of the fixing member 5, so that the connecting member 3 can move up and down along the water inlet pipeline 1, and water can also freely enter the water storage box from the water inlet pipeline. A sealing body 2 is arranged on the upper part of the connecting member 3, which can seal the hole on the fixing member 5. A spring 4 is arranged between the connecting member 3 and the fixing member 5 of the water inlet pipeline, one side of the spring 4 is engaged with the fixing member 5, and the other side is engaged with the supporting portion 6 of the connecting member 3. The supporting portion 6 of the connecting member 3 is located above the protruding structure 22, and the supporting portion 6 can be a part integrally formed at the lower end of the connecting member 3.

[0024] like Figure 5 As shown, when the water level reaches the required height, the floating plate will float horizontally on the water surface, and there will be a certain gap between the protruding structure 22 and the supporting portion 6 of the connecting member 3. The spring will automatically move in the direction of expansion, thereby driving the connecting member to move downward. At this time, the sealing body on the other side of the connecting member will fall down and cling to the fixing member, covering all the water inlet holes, and water will not be able to enter the water storage box through the fixing member. Figure 6 As shown, when the water level drops, the far end of the float plate will move downward together with the water level line. At this time, the raised structure 22 on the left end of the float plate will tilt up and drive the connector 3 to move upward together. The distance between the seal and the fixings of the water inlet pipe will increase, and the holes that were originally covered will be exposed. Water can flow into the water storage box through these holes, thereby controlling the water level. Preferably, a limit rib 23 is provided near the raised structure of the float plate. When the water level is too low, the limit rib 23 will abut against the side wall of the water tank, thereby limiting the float plate to a certain angle and preventing the float plate from rotating too much. Preferably, a second limit rib 14 can also be provided on the inner side of the top of the water tank or on the top of the float plate to limit the float plate when the water level is high to prevent it from tilting too much in the opposite direction. As shown in FIG. Figure 6 As shown, the second limiting rib 14 is arranged on the inner side of the top of the water tank to prevent the right side of the floating plate from tilting too much.

[0025] The present application also relates to a humidifying device, which has a water level control device as described above. Other components of the humidifying device can adopt existing technologies and will not be described in detail.

[0026] The present application also relates to a heater with a humidifying device, wherein the humidifying device has a water level control device as described above, and other components of the humidifying device and the heater can adopt existing technologies and will not be described in detail.

[0027] Although the implementation methods disclosed in this application are as above, the contents described are only implementation methods adopted for facilitating the understanding of this application, and are not intended to limit this application. Any technician in the technical field to which this application belongs can make any modifications and changes in the form and details of implementation without departing from the spirit and scope disclosed in this application, but the scope of patent protection of this application shall still be based on the scope defined in the attached claims.
