When the water in the water tank is reduced, the humidifier is prone to dry burning problem, and it is difficult to maintain the dynamic balance of the water in the water tank.

[0025] Based on the above problems, the present application provides a humidifier, which is automatically provided with a water level control assembly in the water tank. The water level control assembly comprises a floating assembly in the automatic water tank and a blocking piece outside the water inlet of the automatic water tank, which can solve the above technical problems.

[0026] The present application provides a humidifier, which will be described in detail below in combination with the drawings and embodiments.

[0027] The present application provides a humidifier. Please refer to Figure 1 , Figure 1 The present application provides a humidifier. Please refer to

[0028] The bottom of the automatic water supply tank 30 is provided with a water inlet (not labeled), and the water inlet of the automatic water supply tank 30 is connected to the water supply device 10; the water level control assembly 20 includes a floating device 21 and a blocking piece 22, the floating device 21 is arranged in the automatic water supply tank 30; the blocking piece 22 is arranged at the water inlet outside the automatic water supply tank 30, and the blocking piece 22 is connected to the floating device 21, and the blocking piece 22 is driven by the floating device 21 to approach or move away from the water inlet; and the heating device 40 is arranged corresponding to the automatic water supply tank 30. Specifically, the water supply device 10 can be a tap or a water tank. In this embodiment, the water supply device 10 is a water tank, and the bottom of the water tank is connected to the water inlet of the automatic water supply tank 30, wherein the water tank and the automatic water supply tank 30 can be rectangular, cylindrical, irregular polygonal, etc., without specific limitation. The water supply device 10 is used to supplement water for evaporation in the automatic water supply tank 30. Preferably, the floating device 21 is in a plate structure to improve the buoyancy received by the floating device 21; for example, the floating device 21 can be a square plate-shaped floating device 21, and the floating device 21 can also be a rectangular plate-shaped floating device 21, etc. In some other preferred embodiments, the floating device 21 can also be in a hollow structure to further improve the buoyancy received by the floating device 21. Wherein, the blocking piece 22 is located outside the water inlet at the bottom of the automatic water supply tank 30, when the water level in the automatic water supply tank 30 drops below the preset water level line, the floating device 21 drives the blocking piece 22 to drop together, so that the blocking piece 22 does not block the water inlet at the bottom, so that the water supply device 10 can inject water into the automatic water supply tank 30 through the water inlet, so that the water level in the automatic water supply tank 30 rises, avoiding dry burning of the humidifier 100. When the water level in the automatic water supply tank 30 rises to the preset water level line, the floating device 21 drives the blocking piece 22 to move upwards to block the water inlet of the automatic water supply tank 30, avoiding the water supply device 10 from continuing to inject water into the automatic water supply tank 30, thereby avoiding the problem of excessive water in the automatic water supply tank 30 and excessive power consumption of the humidifier 100.

[0029] Different from the prior art, the present application provides a humidifier 100, which includes a water supply device 10, an automatic water supply tank 30, a water level control assembly 20, and a heating device 40. The automatic water supply tank 30 has a water inlet at its bottom, which is connected to the water supply device 10. The water level control assembly 20 includes a float 21 and a blocking member 22. The float 21 is disposed within the automatic water supply tank 30, and the blocking member 22 is disposed at the water inlet outside the automatic water supply tank 30. The blocking member 22 is connected to the float 21 and is driven by the float 21 to move closer to or away from the water inlet. The heating device 40 is disposed corresponding to the automatic water supply tank 30. As described above, a water level control assembly 20 is provided in the automatic water supply tank 30. When the water level in the automatic water supply tank 30 is lower than the preset water level line, the floating device 21 is located below the preset water level line, so that the floating device 21 drives the blocking member 22 to move downward. At this moment, the blocking member 22 does not block the water inlet at the bottom of the automatic water supply tank 30, and the water supply device 10 injects water into the automatic water supply tank 30, thereby avoiding the risk of the humidifier 100 drying out. When the water level in the automatic water supply tank 30 is not lower than the preset water level line, the floating device 21 drives the blocking member 22 to move upward, and the blocking member 22 blocks the water inlet at the bottom of the automatic water supply tank 30, thereby avoiding the problem of excessive water in the automatic water supply tank 30 and excessive power consumption of the humidifier 100. As described above, the dynamic balance of the water in the automatic water supply tank 30 of the humidifier 100 is achieved.

[0030] In this embodiment, to facilitate transportation and ensure greater structural stability of the humidifier 100, the automatic water supply tank 30 can be manufactured by injection molding using a lightweight, pressure-resistant plastic. For example, the material of the automatic water supply tank 30 can include one or more of ABS (acrylonitrile, butadiene, and styrene terpolymer), PC (polycarbonate), PET (polyethylene terephthalate), etc. Furthermore, the floatation device 21 can specifically be a foam plastic floatation device 21, a rubber floatation device 21, an ultralight metal-based composite floatation device 21, or a hollow material floatation device 21, etc. The specific type of the floatation device 21 is not limited.

[0031] In a preferred embodiment, the blocking member 22 is a spherical structure, and the water inlet of the automatic water supply trough 30 is circular; the diameter of the spherical blocking member 22 is larger than the diameter of the circular water inlet. When the water level in the automatic water supply trough 30 is higher than the preset water level, when the floating device 21 drives the blocking member 22 to rise, the blocking member 22 can partially enter the water inlet, making it easier for the blocking member 22 to completely block the water inlet. This prevents the water level in the automatic water supply trough 30 from being higher than the preset water level, and the water inlet is not completely blocked after the blocking member 22 blocks the water inlet, resulting in the risk of water still flowing into the automatic water supply trough 30. In some embodiments, the blocking member 22 can also be a plate-like structure. The specific shape of the blocking member 22 is not limited, as long as the size of the blocking member 22 is larger than the size of the water inlet. Furthermore, in a preferred embodiment, the blocking member 22 is a magnetic member, and the automatic water supply trough 30 is an iron automatic water supply trough 30. When the water level in the automatic water supply tank 30 is higher than a preset water level, the blocking member 22 can be adsorbed outside the water inlet, thereby further preventing water leakage from the water inlet.

[0032] In the present embodiment, the bottom of the water supply device 10 is connected to the water inlet of the automatic water supply trough 30 through the water inlet channel 11; the blocking member 22 is provided in the water inlet channel 11; wherein, the horizontal line of the bottom of the water supply device 10 is higher than the preset water level line of the automatic water supply trough 30. Specifically, the water tank, the water inlet channel 11 and the automatic water supply trough 30 can be an integrally formed structure. The water tank, the water inlet channel 11 and the automatic water supply trough 30 can also be detachably fixed by a threaded structure, a clamping structure, etc., without specific limitation. In the present embodiment, the water supply device 10 is a water tank, and the horizontal line of the bottom of the water tank is set to be higher than the preset water level line of the automatic water supply trough 30, which can ensure that the water in the water tank has the power to flow into the automatic water supply trough 30.

[0033] In this embodiment, the heating device 40 includes a power supply 41 and a heating device 43. The heating device 43 is connected to the power supply 41 and is provided corresponding to the automatic water supply tank 30. Specifically, the heating device 43 may be a heating wire, a heating mesh, a heating ceramic, etc. When the heating device 43 is in the conductive circuit, the heating device 43 can generate heat.

[0034] In this embodiment, the heating device 40 further includes a temperature-controlled switch 42, through which the power supply 41 is connected to the heating device 43. Preferably, the temperature-controlled switch 42 is mounted on the heating device 43. Specifically, the temperature-controlled switch 42 is used to prevent the humidifier 100 from drying out. When the automatic water supply tank 30 is empty, the heating device 43 operates, causing the temperature near it to continue to rise. When the temperature switch 42 detects that the temperature has reached a certain threshold, it automatically disconnects, preventing the risk of drying out.

[0035] In this embodiment, the heating device 40 further includes a humidity switch 44. The power supply 41 is connected to the heating device 43 via the humidity switch 44. Specifically, the humidity switch 44 is configured to automatically disconnect when the ambient humidity reaches a preset humidity, so that the ambient humidity remains constant during operation of the humidifier 100.

[0036] Furthermore, in this embodiment, the heating device 40 also includes a power management chip (not shown), a first switching transistor (not shown), a heating resistor (not shown), and a second switching transistor (not shown). The first switching transistor is connected to the power management chip; the heating resistor is connected to the first switching transistor; and the second switching transistor is connected to the heating resistor, which is also connected to the power management chip. Specifically, the heating device 43 in the above-illustrated embodiment can be a heating resistor. When the heating resistor is energized, it generates heat, causing the water in the automatic water tank 30 to evaporate. In this embodiment, the power management chip serves as the power supply device 41. The first switching transistor is used to implement the function of the temperature control switch 42. In a specific implementation structure in which the temperature control switch 42 is implemented using the first switching transistor, a thermistor (not shown) and a comparator (not shown) connected to the first switching transistor can also be provided. The thermistor can be a thermistor, thermocouple, or temperature sensor. The thermistor senses temperature changes in the heating device 43, and a comparator is connected to the thermistor. The comparator compares the signal output by the thermistor with a preset reference voltage, i.e., a temperature threshold. When the temperature reaches or exceeds the preset temperature, the output level signal of the comparator changes, causing the first switch tube to change from the on state to the off state, thereby turning off the heating device 43 in time to avoid the risk of dry burning of the humidifier 100. The function of the humidity switch 44 is also realized by the second switch tube. In a specific implementation structure for realizing the function of the humidity switch 44 by the second switch tube, a humidity sensor and a comparator connected to the second switch tube can also be provided. The humidity sensor senses the change in humidity, and the comparator is connected to the humidity sensor. The comparator compares the signal output by the humidity sensor with a preset reference voltage, that is, the preset humidity. When the humidity reaches or exceeds the preset humidity, the output level signal of the comparator changes, causing the second switch tube to change from the on state to the off state, so as to shut down the humidifier 100 when the ambient humidity reaches the preset humidity, so that when the humidifier 100 is working, the environment is kept at the set humidity.

[0037] In some embodiments, the heating device 40 further includes a push-button switch device (not shown), which is connected to the gate of the first switching transistor and the gate of the second switching transistor. Specifically, the push-button switch device serves as a user operation button. After the humidifier 100 is automatically shut down due to a dry-burn risk or the humidity reaches a preset humidity, the user can use the push-button switch device to restart the humidifier 100 after the dry-burn risk is eliminated.

[0038] Different from the prior art, the application provides a humidifier 100, which comprises a water supply device 10, an automatic water supply tank 30, a water level control assembly 20 and a heating device 40. The automatic water supply tank 30 is provided with a water inlet at the bottom, and the water inlet of the automatic water supply tank 30 is connected with the water supply device 10; the water level control assembly 20 comprises a floating device 21 and a blocking piece 22, the floating device 21 is arranged in the automatic water supply tank 30, the blocking piece 22 is arranged at the water inlet outside the automatic water supply tank 30, the blocking piece 22 is connected with the floating device 21, and the blocking piece 22 is driven by the floating device 21 to move close to or away from the water inlet; and the heating device 40 is arranged corresponding to the automatic water supply tank 30. As described above, the water level control assembly 20 is arranged in the automatic water supply tank 30, when the water level in the automatic water supply tank 30 is lower than a preset water level line, the floating device 21 is below the preset water level line, so that the floating device 21 drives the blocking piece 22 to move downward, at this moment, the blocking piece 22 does not block the water inlet at the bottom of the automatic water supply tank 30, the water supply device 10 injects water into the automatic water supply tank 30, and the risk of dry burning of the humidifier 100 is avoided. When the water level in the automatic water supply tank 30 is not lower than the preset water level line, the floating device 21 drives the blocking piece 22 to move upward, and the blocking piece 22 blocks the water inlet at the bottom of the automatic water supply tank 30, so that the problem of excessive water in the automatic water supply tank 30 and excessive power consumption of the humidifier 100 is avoided, and the dynamic balance of the water in the automatic water supply tank 30 of the humidifier 100 is realized.
