It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0036] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] like Figures 1 to 7As shown, this utility model embodiment provides a humidifier start-stop control structure, including a water tank 11, a wet film assembly 2, a submersible pump 3, a water inlet 4, a cover 12, a fan 5, a control circuit board 61, a power supply 7, a Hall sensor 81, and a magnet 82. The water tank 11 is used to store water. The wet film assembly 2 is detachably installed in the water tank 11. A water pump mounting base 31 is provided on the side of the water tank 11. The submersible pump 3 is installed in the water pump mounting base 31. The water inlet 4 is located on the side of the wet film assembly 2. The water inlet of the water inlet 4 is connected to the submersible pump 3. The submersible pump 3 is used to pump water from the water tank 11 to the wet film assembly 2. When the humidifier is in operation, the submersible pump 3 pumps water from the bottom of the water tank 11. Water is drawn from the water tank 11 and transported to the wet membrane assembly 2 through the water receiving base 4, keeping the wet membrane assembly 2 continuously moist. The cover 12 is placed on top of the water tank 11. The cover 12 has an air inlet 121 around its periphery and an air outlet 122 at its top. The fan 5 is located at the bottom of the cover 12 and is used to generate airflow to remove moisture from the wet membrane assembly 2 and diffuse it into the outside air. When the fan 5 is started, it can draw in outside air through the air inlet around the cover 12 and guide the airflow through the wet membrane assembly 2, so that the air can fully contact the moisture on the surface of the wet membrane assembly 2. The moist airflow is then discharged outward through the air outlet 122 at the top of the cover 12, thereby achieving mist-free humidification.

[0038] The power base 7 is located on the inner side wall of the cover 12. The bottom of the power base 7 is provided with a first coupler 71, and the top of the water pump mounting base 31 is provided with a second coupler 72. The second coupler 72 is electrically connected to the submersible pump 3. When the cover 12 is placed on the water tank 11, the second coupler 72 is electrically connected to the first coupler 71. When the cover 12 is closed on the water tank 11, the first coupler 71 and the second coupler 72 form an electrical connection, thereby realizing the power supply to the submersible pump 3. The contact power supply method without exposed wires can automatically realize power supply when the user completes the action of closing the cover, without the need for the user to manually plug and unplug the wires, effectively improving the convenience of using the humidifier.

[0039] The control circuit board 61 and the Hall sensor 81 are respectively disposed inside the cover 12, and the Hall sensor 81 is electrically connected to the control circuit board 61. The magnet 82 is disposed on the top of the water receiving base 4, and the magnet 82 is located directly below the Hall sensor 81. The Hall sensor 81 is used to inductively connect with the magnet 82 when the cover 12 is placed on the water tank 11. When the cover 12 is correctly installed on the water tank 11, the magnet 82 and the Hall sensor 81 can form a magnetic induction, thereby sending a cover-closing signal to the control circuit to accurately identify whether the cover 12 is closed in place, avoiding accidental start-up of the device when the cover 12 is not in place or is accidentally opened, preventing dry operation, water leakage and electrical failure, etc., and effectively improving the safety and reliability of the humidifier during use.

[0040] like Figure 4 As shown, the wet membrane assembly 2 further includes a wet membrane support 21 and a wet membrane body 22. The wet membrane body 22 surrounds the periphery of the wet membrane support 21. The top of the wet membrane support 21 is provided with a water spray channel 211, and the water spray channel 211 is provided with water spray holes 212. The water spray holes 212 are used to allow water in the water spray channel 211 to spray onto the wet membrane body 22. This arrangement allows water to drip evenly from above onto the wet membrane body 22, realizing a top-down immersion water supply method. Compared with the traditional bottom-up water absorption mode of wet membranes, this can effectively improve the wetting speed and uniformity of the wet membrane body 22, thereby improving the humidification efficiency.

[0041] like Figure 4 As shown, the water receiving base 4 is further provided with a water receiving pipe 41 inside. One end of the water receiving pipe 41 is connected to the submersible pump 3, and the other end of the water receiving pipe 41 is connected to the water spray channel 211. In this way, the water circuit connection structure can be simplified, and it is convenient to disassemble and clean the water receiving pipe 41.

[0042] like Figure 5 and Figure 6 As shown, the bottom of the cover 12 is provided with an inner cover 13, and the inner cover 13 is provided with a first receiving groove 130. The Hall sensor 81 is disposed in the first receiving groove 130. In this way, the Hall sensor 81 can be prevented from becoming loose or shifting during use, and its sensing surface is always kept facing the position of the magnet 82, thereby improving the accuracy of magnetic induction triggering when the cover 12 is closed.

[0043] like Figure 6 As shown, the power socket 7 and the inner cover 13 are injection molded as a single unit, thereby improving assembly efficiency and structural strength, and avoiding unstable electrical connections due to loose parts. The power socket 7 is provided with a power interface 70 on its side, which is used to connect an external power cord for power supply.

[0044] like Figure 4 As shown, the top of the water receiving base 4 is provided with a second receiving groove 42, and the magnet 82 is disposed in the second receiving groove 42. The inner wall of the second receiving groove 42 is provided with a limiting rib 421 along the circumferential direction. The limiting rib 421 is used to limit the magnet 82 from slipping out of the second receiving groove 42, and prevent it from being displaced or falling off due to vibration during transportation or operation, thereby improving the recognition stability of the humidifier opening and closing control structure.

[0045] like Figure 6 As shown, it further includes a humidity sensor 91, which is located in the air inlet 121 on the side of the cover 12. The humidity sensor 91 is electrically connected to the control circuit board 61 to detect the air humidity of the external environment. The humidity sensor 91 is electrically connected to the control circuit board 61 so that the humidifier can automatically control the start and stop of the fan 5 or the water pump and the operating mode according to the humidity change, so as to achieve constant humidity control, improve humidification efficiency and user comfort.

[0046] like Figure 7 As shown, it further includes a liquid level sensor 92, which is installed in the water pump mounting base 31. The liquid level sensor 92 is electrically connected to the second coupler 72 to detect the water level in the water tank 11, realize automatic identification and feedback control of low water level state. When the water level is lower than the set threshold, the control circuit board 61 can stop the submersible pump 3 from running, avoid water pump damage or safety hazards caused by dry running, and improve the operating reliability and service life of the humidifier.

[0047] like Figure 1 and Figure 6 As shown, it further includes an operation display panel 62, which is located on the top of the cover 12. The operation display panel 62 is electrically connected to the control circuit board 61. The operation display panel 62 allows users to easily view various operating information of the humidifier, such as humidity level or working mode, during daily use, thereby improving the human-computer interaction experience and enhancing the product's intelligence and ease of operation.

[0048] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
