[0029] The detection element is a Hall sensor, and the float 3 includes a slide bar 31, a float ball 32 is provided at the lower end of the slide bar 31, and a sensing ball 34 is provided at the upper end, and a magnet is provided in the sensing ball 34. In this embodiment, the detection element is taken as an example of a Hall sensor, and the detection element can also be a contact switch, or two conductive needles are used as the detection element, and the sensing ball is set as a metal conductive ball. When the sensing ball made of metal material touches the detection element, a path is formed between the sensing ball and the detection element, so that the alarm device on the circuit board sends an alarm signal.

[0030] The inner wall of the water tank 2 is provided with a sleeve 33, and the slide rod 31 is located in the sleeve 33. The inner wall of the water tank 2 is provided with a fixed arm 21, and the end of the fixed arm 21 is provided with an arc-shaped clamp 23, and the sleeve 33 is installed in the arc-shaped clamp 23. The upper outer wall of the sleeve 33 is provided with an upper retaining ring 331, and the lower outer wall is provided with a lower retaining ring 332. The lower side of the upper retaining ring 331 is in close contact with the upper surface of the arc-shaped clamp 23, and the upper side of the lower retaining ring 332 is in close contact with the lower surface of the arc-shaped clamp 23. The sleeve is provided so that the float can move up and down in the water tank with the water surface. When the water surface is submerged above the floating ball at the lower end of the slide rod, the float floats on the water surface under the buoyancy of the water. When the water surface is higher than a certain height, the induction ball at the upper end of the slide rod contacts the detection element at the bottom of the host. At this time, it is considered that the water surface has reached the upper limit, and the circuit board controls the alarm device to send out an alarm signal.

[0031] A base 5 is mounted on the bottom of the water tank 2 by means of snaps or threads.

[0032] Embodiment 1: The middle of the base 5 is sunken downward to form a sunken portion, and the side wall of the sunken portion is provided with an L-shaped buckle convex edge 51, and a protrusion 22 corresponding to the buckle convex edge 51 is provided at the bottom of the water tank 2, and a limit bayonet is formed between the buckle convex edge 51 and the bottom of the base 5, and the protrusion 22 is placed in the limit bayonet. In this embodiment, the base and the water tank are movably connected by a buckle.

[0033] Embodiment 2: The middle part of the base 5 is sunken downward to form an inner concave portion, the inner wall of the inner concave portion is provided with an internal thread, a protrusion corresponding to the inner concave portion is provided at the bottom of the water tank 2, and the side wall of the protrusion is provided with an external thread. In this embodiment, the base and the water tank are movably connected by a thread.

[0034] The detachable base is used to stabilize the position of the water tank. When storing, the base can be removed and placed in the water tank, which reduces the volume of the humidifier after packaging and makes the humidifier occupy less space. When storing or packing the humidifier, the base can be unscrewed and removed, and the base can be placed in the water tank along the diagonal line of the water tank, which can reduce the volume of the humidifier packaging and save storage and warehousing space.

[0035] A water inlet pipe 13 is arranged at the upper end of the main unit 1, and a water outlet pipe 14 is arranged at the lower end of the main unit 1 at a position corresponding to the water inlet pipe 13. The water outlet pipe 14 is connected with the water tank 2, and water is poured into the water inlet pipe 13, passes through the main unit 1, and flows out from the water outlet pipe 14 to the water tank 2; when the humidifier needs to be filled with water, the flip cover on the main unit 1 can be directly flipped upward to expose the water inlet pipe, and water can be directly added to the water inlet pipe. At this time, water will flow down from the water inlet pipe, pass through the water outlet pipe and fall into the water tank. The structure of this main unit can facilitate water addition, and water can be directly added to the water tank without removing the main unit, which is more convenient to use.

[0036] A water pipe seat 24 is provided on the upper inner wall of the water tank 2, and a water inlet pipe 11 is provided at the lower end of the water pipe seat 24. The lower end of the water inlet pipe 11 extends into the bottom of the water tank 2, and a silent filter 12 is provided at the lower end of the water inlet pipe 11; a silent filter with filter holes is provided, and when the water suction pipe absorbs water, water is sucked into the water suction pipe from the filter holes, and the water surface filtered by the silent filter will not produce large ripples, which can reduce the water sound generated by the shaking of the water body during pumping, thereby improving the quietness of the humidifier; the water inlet end of the water pump extends out of the main unit 1. After the main unit 1 is installed in the water tank 2, the water inlet end of the water pump is inserted into the water pipe seat 24 to form a sealed water inlet channel, or the water pipe seat 24 is inserted into the water inlet end of the water pump to form a sealed water inlet channel. The water inlet end of the water pump is sealed and connected to the water inlet pipe, and the water inlet pipe is fixed by a water pipe seat in the water tank. The water pump is separated from the water inlet pipe. When the main unit is removed, the water inlet pipe will not be taken out together with it, thereby optimizing the structure of the humidifier and improving the integrity of the humidifier.
