[0025] With the arrangement of a water drain valve 4 capable of controlling the opening and closing of the first water drain port 11, and a floating ball member 5 capable of pushing the water drain valve 4 upward to open the first water drain port 11, when the water level in the water storage chamber 31 drops, the floating ball member 5 pushes the water drain valve 4 to open, allowing water to flow from the water tank 1 into the water storage chamber 31, realizing the automatic water replenishment function; with the arrangement of a heating chamber 6 and a second water drain port 32 through which water supply flows from the water storage chamber 31 into the heating chamber 5, compared with the traditional steam humidifier that heats the water in the entire water tank, the heating assembly 2 can heat the water falling into the heating chamber 6 to generate steam, reducing unnecessary heating, lowering energy consumption, and improving heating efficiency; by arranging the water tank 1, the water storage box 3, and the heating assembly 2 in layers, with the water tank 1, the water storage chamber 31, and the heating chamber 6 arranged in sequence from top to bottom, while reducing the scale problem that may occur due to long-term heating of a large amount of static water, it helps to simplify maintenance and improve efficiency.
[0026] The water drain valve 4 includes a plug 41 provided above the first water drain port 11 and a cylinder 42 connected to the plug 41 and passing through the first water drain port 11. There is a gap between the cylinder 42 and the edge of the first water drain port 11, and an elastic member 43 is provided between the cylinder 42 and the water tank 1 and can push the cylinder 42 downward so that the plug 41 covers the first water drain port 11.
[0027] The plug 41 is provided above the first water drain port 11 and can physically contact and block the first water drain port 11 to ensure tightness. The cylinder 42 is connected to the plug 41 and controls the opening or blocking of the first water drain port 11 by moving up and down. There is a gap between the cylinder 42 and the edge of the first water drain port 11, allowing water to flow into the water storage chamber 31 through the gap. The elastic member 43 is provided between the cylinder 42 and the water tank 1. When the water level in the water storage chamber 31 is relatively high, it can provide a downward acting force to make the plug 41 closely adhere to the first water drain port 11 to achieve the closed state.
[0028] In the embodiment, the elastic member 43 is a return spring, and the elastic member 43 can also be realized by means of an elastic rubber ring or a spring piece, etc.
[0029] In the embodiment, the shape of the plug 41 is conical to ensure a good matching degree with the first water drain port 11.
[0030] A water drain seat 12 is provided at the bottom of the water tank 1, the first water drain port 11 is provided on the water drain seat 12, and the water drain seat 12 is provided with a guide ring 121 through which the cylinder 42 passes.
[0031] Through the arrangement of the guide ring 121, the cylinder 42 moves up and down along the guide ring 121, reducing the swing of the cylinder 42 and increasing stability.
[0032] One end of the elastic member 43 abuts against the lower part of the guide ring 121.
[0033] By arranging that one end of the elastic member 43 abuts against the lower part of the guide ring 121, a support point is provided for one end of the elastic member 43, ensuring the correct installation and stable operation of the elastic member 43.
[0034] In the embodiment, a water dropping seat 12 is detachably provided at the bottom of the water tank 1. By providing the detachable water dropping seat 12 for carrying the first water dropping port 11, it is convenient for maintenance and cleaning, and is also convenient for replacing or repairing the water dropping valve 4 assembly.
[0035] A float bracket 33 is provided on the water storage box 3. The float member 5 is rotatably connected to the float bracket 33. The float member 5 has a rotating portion 51 that can drive the float member 5 to rotate as the water level changes, and a pressing portion 52 that can press the column 42 to move upward.
[0036] The float bracket 33 can provide a stable support point to ensure the normal operation of the float member 5. By being rotatably connected to the float member 5, the float member 5 can freely rotate as the water level changes. The float member 5 includes a rotating portion 51 and a pressing portion 52. As the water level changes, the float member 5 rotates through the rotating portion 51 and presses the column 42 through the pressing portion 52, thereby controlling the opening and closing of the water dropping valve 4. Automatic control is achieved using simple mechanical principles, and all components are easy to inspect and replace, reducing the maintenance cost.
[0037] A float groove 521 with an opening downward is formed in the lower part of the pressing portion 52.
[0038] The float groove 521 with an opening downward can provide additional buoyancy while reducing the weight, helping to maintain the stability of the float member 5 in water. Even when the pressing portion 52 is impacted by the water falling from the first water dropping port 11 or in the case of water level fluctuations, it can still maintain good performance.
[0039] The humidifier further includes an inner tank 8. The water tank 1 is installed in the inner tank 8. The heating chamber 6 is provided at the bottom of the inner tank 8. A sealing ring 34 is provided around the outer periphery of the water storage box 3, and the sealing ring 34 abuts against the inner wall of the inner tank 8.
[0040] The heating chamber 6 is provided at the bottom of the inner tank 8, and water can naturally flow to the heating chamber 6 by gravity. The sealing ring 34 is provided around the outer periphery of the water storage box 3 to ensure the sealing between the heating chamber 6 and the water storage box 3, ensuring that the steam is discharged from the discharge port 7.
[0041] In the embodiment, a support frame is provided at the bottom of the water tank 1, and a support portion for placing the support frame is provided on the upper part of the water storage box 3. By providing the support frame and the support portion, there is enough space between the water tank 1 and the water storage box 3 for installing the water dropping valve 4 and the float member 5.
[0042] The water storage box 3 is provided with a protruding part 35 extending downward, and the second water outlet 32 is penetrated and arranged on the protruding part 35.
[0043] Through the arrangement of the protruding part 35 and the second water outlet 32 penetrated and arranged on the protruding part 35, the water falling from the second water outlet 32 can be accurately positioned above the heating cavity 6, restricting the water from flowing out around along the bottom of the water storage box 3.
[0044] The height of the exhaust port 7 is higher than the height of the water storage cavity 31.
[0045] Through the setting that the height of the exhaust port 7 is higher than the height of the water storage cavity 31, it can prevent the water level in the heating cavity 6 from being too high to cover the exhaust port 7, thereby causing the steam to be unable to be discharged.
[0046] The heating assembly 2 includes a heating plate 21 and a thermostat 22 capable of controlling the temperature of the heating plate 21, and a temperature sensor 23 is arranged between the water storage box 3 and the heating assembly 2.
[0047] The heating plate 21 can heat the water in the water storage cavity 31 to evaporate it into steam. Through the setting of the thermostat 22, the working temperature of the heating plate 21 is controlled, ensuring the safety and effectiveness of the heating process. The temperature sensor 23 is arranged between the water storage box 3 and the heating assembly 2. By monitoring the temperature in the heating cavity 6, it provides a feedback signal for the thermostat 22 to accurately control the heating process and ensure the stable generation of steam.
[0048] In the embodiment, the humidifier further includes a steam pipe 9. The steam pipe 9 has a connecting part 91 communicated with the exhaust port 7 and an extending part 92 extending upward. The connecting part 91 is communicated with the exhaust port 7, which helps to guide the steam to flow out of the heating cavity 6 smoothly. The extending part 92 extends upward. By guiding the steam to a higher position, it helps the steam to spread into the room faster. While improving the humidification efficiency, the higher position can reduce the chance of the steam contacting the surface of the device and reduce the risk of the device surface being damaged by the high-temperature steam.
