[0042] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0043] Combination Figure 1-4As shown, the embodiment of the present disclosure provides a humidity control device, including a housing, a water tank 100 and a drainage pump 121. The water tank 100 is arranged in the housing, and is provided with a water pumping chamber 110, a water pump chamber 120 and a drainage chamber 130; the water pumping chamber 110 is connected to the water pump chamber 120 through a through hole 151, the water pump chamber 120 is connected to the drainage chamber 130 through an overflow groove 141, and the drainage chamber 130 is connected to the external environment through a drainage port 131; the drainage pump 121 is arranged in the water pump chamber 120, and its drainage pipe 122 is connected to the drainage chamber 130; and after the water in the water pumping chamber 110 enters the water pump chamber 120, it can enter the drainage chamber 130 through the drainage pump 121, and / or can enter the drainage chamber 130 through the overflow groove 141.

[0044] In this embodiment, clean water for humidification is filled into the water pumping chamber 110, and the clean water can enter the water pump chamber 120 through the through-hole 151. Here, a water pumping fan is arranged in the water pumping chamber 110, and the clean water is thrown up when the water pumping fan rotates, and the air is humidified after contacting the thrown up water. The drainage pump 121 is arranged in the water pump chamber 120 to avoid being arranged in the water pumping chamber 110 to affect the installation and operation of the water pumping fan. In addition, when the water level of the clean water filled in the water pumping chamber 110 is too high, the water can be discharged into the drainage chamber 130 through the drainage pump 121, and / or the water can be discharged into the drainage chamber 130 through the overflow groove 141. Finally, the water is discharged into the external environment through the drainage port 131. In this way, the water tank 100 can be effectively prevented from overflowing, the normal operation of the humidity control device can be guaranteed, and the user experience can be improved.

[0045] Optionally, the humidity control device further comprises a fan assembly, which is used to drive air to blow over the water tank 100. A water pumping fan is provided in the water pumping room 110, and the water pumping fan is used to throw the water in the water pumping room 110.

[0046] In this embodiment, the humidity control device can distribute moisture into the indoor air through the water fan and the blower assembly, thereby increasing the indoor humidity and helping to improve the indoor air quality. When the indoor humidity is low, allergens such as dust and pollen in the air can easily irritate the respiratory tract, causing problems such as coughing and asthma. The humidity control device can increase the indoor humidity and reduce the activity of these allergens, thereby improving respiratory health. In a dry environment, the skin easily loses moisture and becomes dry and rough. Using a humidity control device can increase the indoor humidity, provide a suitable moisture environment for the skin, and alleviate the problem of dry skin.

[0047] Optionally, the water-spraying fan is a centrifugal fan, whose working principle mainly relies on centrifugal force. When the water-spraying fan rotates, water is thrown into tiny particles under the action of centrifugal force, which greatly increases the evaporation surface area of ​​the liquid. And under the action of the airflow blown by the fan assembly, the surface wind speed of the liquid increases, accelerating the diffusion of gas molecules.

[0048] In this embodiment, the water pumping fan includes a motor and an impeller, and the drive shaft of the motor is connected to the impeller. The motor is the power source of the centrifugal fan and is responsible for driving the impeller to rotate. The motor is usually composed of a stator and a rotor, and a magnetic field is generated by an electric current, so that the rotor rotates under the action of magnetic force. The impeller is composed of a plurality of blades, and the shape and number of the blades can be designed according to actual needs to achieve the best water pumping effect, which is not limited in this application. When the motor drives the impeller to rotate, the plurality of blades throw up the water in the water pumping chamber 110.

[0049] Alternatively, if Figure 1 As shown, the bottom plate of the drainage chamber 130 is inclined downward from the first side to the second side, and the drainage port 131 is located on the second side of the bottom plate.

[0050] In this embodiment, since the bottom plate of the drainage chamber 130 is inclined, water can flow to the second side more easily and finally be discharged through the drainage port 131. This is conducive to accelerating the drainage speed and reducing the retention time of water in the drainage chamber 130, thereby effectively preventing water accumulation or liquid overflow. In addition, since water naturally flows to the inclined bottom plate, there will be relatively less debris or sediment accumulated at the drainage port 131. This is conducive to reducing the risk of clogging of the drainage port 131 and ensuring the smooth operation of the drainage system of the humidity control device.

[0051] Optionally, the bottom plate of the drainage chamber 130 is inclined downward from the first side toward the second side, and the drainage pipe 122 is located on the second side of the bottom plate.

[0052] In this embodiment, water in the water pumping chamber 110 enters the water pump chamber 120 through the through-hole 151, and the drainage pump 121 discharges the water into the drainage chamber 130 through the drainage pipe 122. Here, the end of the drainage pipe 122 is located on the second side of the bottom plate, and the water flows along the bottom plate toward the inclined first side after being discharged from the drainage pipe 122. In this way, the drainage pump 121 can flush the bottom plate while draining water, thereby effectively preventing debris from being deposited on the bottom plate of the drainage chamber 130.

[0053] Optionally, the inclination angle of the bottom plate of the drainage chamber 130 ranges from 30° to 60°.

[0054] Exemplarily, the inclination angle of the bottom plate of the drainage compartment 130 can be selected to be 30°, 32°, 35°, 38°, 40°, 43°, 45°, 47°, 50°, 53°, 55°, 57° or 60°.

[0055] Optionally, the bottom plate of the water pumping chamber 110 is arranged horizontally, so as to facilitate the storage of more purified water and the installation of a water pumping fan.

[0056] Optionally, the bottom plate of the water pump chamber 120 is arranged horizontally, so as to facilitate storage of more purified water and installation of the drainage pump 121.

[0057] Alternatively, if Figure 2 As shown, the drainage chamber 130 and the water pump chamber 120 share a first baffle 140 ; ​​an overflow groove 141 is opened on the top of the first baffle 140 , and when the water level in the water pump chamber 120 exceeds the overflow groove 141 , water flows into the drainage chamber 130 from the overflow groove 141 .

[0058] In this embodiment, the drain pump 121 is usually composed of a motor, a cable and other electrical components. Due to long-term operation in an underwater environment, there is a possibility that the drain pump 121 fails and cannot operate. Assuming that the water pump fails, if the water in the water pump chamber 120 cannot be discharged into the drain chamber 130 in time, overflow will occur. At this time, under the action of the overflow groove 141, the water in the water pump chamber 120 is discharged into the drain chamber 130 through the overflow groove 141, and then discharged to the external environment through the drain port 131. In this way, in the event of a failure of the drain pump 121, the overflow groove 141 design can effectively prevent the water tank 100 from overflowing, thereby ensuring the normal operation of the humidity control device.

[0059] Alternatively, if Figure 2 As shown, the height of the first baffle plate 140 is the same as the height of the side plate of the water tank 100 .

[0060] In this embodiment, when the first baffle 140 is at the same height as the side plate of the water tank 100, the structure of the entire water tank 100 has good support and stability in the vertical direction. This is conducive to reducing deformation or displacement caused by water pressure or external force. In addition, since the first baffle 140 is at the same height as the side plate of the water tank 100, no additional adjustment or customization is required during manufacturing and installation. This reduces the complexity of installation and maintenance of the first baffle 140 and improves work efficiency.

[0061] Optionally, the overflow groove 141 is opened at the edge of the top of the first baffle 140 and is constructed as a U-shaped notch opening upward.

[0062] In this embodiment, the structure of the U-shaped overflow groove 141 can prevent water from splashing out when discharged to a certain extent, thereby playing a splash-proof role. In addition, the structure of the U-shaped overflow groove 141 is relatively simple, does not require a complex manufacturing process, and is conducive to reducing costs.

[0063] Alternatively, if Figure 3As shown, the drainage pipe 122 of the drainage pump 121 crosses the overflow groove 141 and extends into the drainage chamber 130.

[0064] In this embodiment, there is no need to open an additional hole on the first baffle 140 so that the drain pipe 122 passes through the hole and extends into the drain chamber 130. In addition, the drain pipe 122 is arranged across the overflow groove 141, and the overflow groove 141 provides an installation space for the drain pipe 122. The drain pipe 122 has little effect on the water flow in the overflow groove 141, thereby optimizing the pipeline layout of the drainage system.

[0065] Optionally, the arrangement height of the drain pipe 122 is less than or equal to the height of the side plate of the water tank 100. In this way, the drain pipes 122 are all located inside the water tank 100, reducing the impact of the pipeline layout on the outer pipe of the water tank 100.

[0066] Alternatively, if Figure 4 As shown, the water pumping chamber 110 and the water pump chamber 120 share a second baffle 150 ; a through hole 151 is opened at the bottom of the second baffle 150 , and the water in the water pumping chamber 110 enters the water pump chamber 120 through the through hole 151 .

[0067] In this embodiment, the pumping chamber 110 and the water pump chamber 120 share the second baffle 150, and a through hole 151 is provided at the bottom of the second baffle 150, so that the structure of the entire drainage system can be simplified. In this way, it is avoided to use additional pipes or connecting equipment to make the clean water flow from the pumping chamber 110 to the water pump chamber 120, which is conducive to reducing costs. In addition, the size of the through hole 151 can be flexibly adjusted according to the needs of the humidity control device, thereby controlling the water flow speed between the pumping chamber 110 and the water pump chamber 120.

[0068] Alternatively, if Figure 4 As shown, the height of the second baffle plate 150 is the same as the height of the side plate of the water tank 100 .

[0069] In this embodiment, when the second baffle 150 is at the same height as the side plate of the water tank 100, the structure of the entire water tank 100 has good support and stability in the vertical direction. This is conducive to reducing deformation or displacement caused by water pressure or external force. In addition, since the second baffle 150 is at the same height as the side plate of the water tank 100, no additional adjustment or customization is required during manufacturing and installation. This reduces the complexity of installation and maintenance of the second baffle 150 and improves work efficiency.

[0070] Optionally, the through hole 151 is opened at the edge of the bottom of the second baffle 150 and is configured as a U-shaped notch opening downward. In this way, the structure of the U-shaped through hole 151 is relatively simple, does not require a complex manufacturing process, and is conducive to reducing costs.

[0071] Optionally, the first baffle 140 and the second baffle 150 are arranged perpendicular to each other.

[0072] In this embodiment, by vertically arranging the first baffle 140 and the second baffle 150, the space can be more effectively utilized and unnecessary gaps can be reduced. This layout can reasonably divide the drainage chamber 130 and the water pump chamber 120 in a limited space, thereby improving the utilization efficiency of the space.

[0073] Optionally, a first float switch is provided in the water pumping chamber 110, and the first float switch corresponds to a low water level and a middle water level; the humidity control device further comprises a water inlet solenoid valve, and an external water source flows into the water pumping chamber 110 through the water inlet solenoid valve; and when the water level in the water pumping chamber 110 reaches a low water level, the humidity control device starts humidification; when the water level in the water pumping chamber 110 reaches a middle water level, the water inlet solenoid valve is closed.

[0074] In this embodiment, when the water inlet solenoid valve is open, the external water source flows into the water pumping chamber 110 through the water inlet solenoid valve. As the water level rises to the low water level, the first float switch is triggered. At this time, the humidity control device starts the humidification operation, and the water pumping fan rotates to throw the water. As the water level continues to rise to the middle water level, the water inlet solenoid valve is closed to block the external water source from continuing to enter the water pumping chamber 110. In this way, by adjusting the opening degree or opening time of the water inlet solenoid valve, the water level in the humidification process can be accurately controlled, and then the indoor humidity can be controlled to meet different environmental requirements.

[0075] For example, a higher humidity is required indoors. In order to meet the humidity requirement, the opening of the water inlet solenoid valve is increased so that the external water source is continuously and quickly filled into the water pumping chamber 110. At the same time, the speed of the water pumping fan is increased to quickly throw more clean water so that the air drives the moisture to quickly spread into the indoor air. In this way, the required humidity can be quickly reached indoors.

[0076] In another example, a lower humidity is required indoors. In order to meet the humidity requirement, the opening of the water inlet solenoid valve is reduced so that the external water source is slowly filled into the water pumping room 110. At the same time, the speed of the water pumping fan is reduced to throw up less clean water. In this way, the water level in the water pumping room 110 can be prevented from rising too quickly, the use frequency of the drainage pump 121 can be reduced, and the required humidity can be met while reducing energy consumption.

[0077] Optionally, a second float switch is further provided in the water pumping chamber 110, and the second float switch corresponds to a high water level; and when the water level in the water pumping chamber 110 reaches the high water level, the drainage pump 121 starts drainage.

[0078] In this embodiment, when the water inlet solenoid valve is open, the external water source flows into the water pumping chamber 110 through the water inlet solenoid valve. If the water inlet solenoid valve fails and causes continuous water injection, the water level in the water pumping chamber 110 will rise to a high water level. At this time, the second float switch is triggered, and the drainage pump 121 immediately starts the drainage work, draining the water into the drainage chamber 130, and finally draining it to the external environment through the drain port 131. In this way, in the case of a water inlet solenoid valve failure, the drainage pump 121 can effectively prevent the water tank 100 from overflowing, thereby ensuring the normal operation of the humidity control device.

[0079] Optionally, the external water source flows into the water pumping chamber 110 through the water inlet pump, the pressure reducing valve and the water inlet solenoid valve in sequence.

[0080] In this embodiment, by providing a water inlet pump, the water supply pressure of the external water source can be increased, ensuring that the water flow can smoothly enter the pressure reducing valve and the water inlet solenoid valve, and finally fill the water pumping chamber 110. In this way, it is beneficial to ensure the normal operation of the humidity control device when the water supply distance is far or the water source pressure is low. By providing a pressure reducing valve, the high-pressure water flow provided by the water inlet pump is reduced to a suitable pressure range, thereby stabilizing the water supply pressure and preventing adverse effects on the water system of the humidity control device due to water pressure fluctuations.

[0081] Optionally, the height of the overflow tank 141 is greater than or equal to the height of the water level corresponding to the second float switch.

[0082] In this embodiment, the second float switch corresponds to the high water level. When the water level in the pumping chamber 110 reaches the high water level, the drain pump 121 is started. At the same time, water can flow into the drain chamber 130 through the overflow groove 141, and finally be discharged to the external environment through the drain port 131. In this way, the height setting of the overflow groove 141 effectively assists the drain pump 121 in draining. And in the event of a failure of the drain pump 121, the overflow groove 141 will serve as the main drainage method.
