[0061] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0062] Combine Figures 1 to 8 As shown, an embodiment of the present disclosure provides a drainage system 10 for a fresh air humidifier. The drainage system 10 for a fresh air humidifier includes a water tank 11, a pumping assembly 20, and a hot air assembly 30. The water tank 11 includes a drain port 112. The pumping assembly 20 is connected to the drain port 112 and is used to pump water out of the water tank 11. The hot air assembly 30 is disposed outside the water tank 11. The hot air assembly 30 is used to deliver hot air to the water tank 11 to dry out any residual water in the water tank 11.

[0063] In this embodiment, the pumping assembly 20 is connected to the drain port 112 of the water tank 11, allowing the pumping assembly 20 to pump water out of the water tank 11. When the fresh air humidifier 50 is not used for an extended period of time, the pumping assembly 20 pumps out the water in the water tank 11, thereby removing most of the water from the water tank 11. At this point, a small amount of water may remain in the water tank 11.

[0064] In this embodiment, the hot air assembly 30 is located outside the water tank 11 and can deliver hot air to the water tank 11 to dry out any residual water within. In other words, the hot air flowing through the water tank 11 dries out any remaining water within. This eliminates the problems of deterioration, odor, and bacteria caused by residual water, extends the life of the water tank 11, and enhances the user experience.

[0065] Optionally, the fresh air humidifier 50 includes a ceiling-mounted fresh air humidifier.

[0066] Combine Figures 1 to 3 as well as Figure 8 As shown, in some embodiments, the water tank 11 includes a tank body 111. The tank body 111 defines a water storage chamber 113 with a top opening. A drain port 112 is provided at the bottom of the tank body 111 and communicates with the water storage chamber 113.

[0067] In this embodiment, the box body 111 defines a water storage chamber 113 with a top opening for storing water. When the fresh air humidifier 50 is used to adjust the air humidity, the water in the water storage chamber 113 can be used to provide a comfortable indoor environment for the user.

[0068] If the user plans to not use the fresh air humidifier 50 for an extended period, the water in the water tank 11 can be drained. Specifically, the pumping assembly 20 is used to first pump out most of the water in the water tank 11. If a small amount of water remains in the water tank 11, the remaining water will be distributed along the walls of the water storage chamber 113. The opening at the top of the water storage chamber 113 allows hot air to flow in and out of the water storage chamber 113, accelerating the drying of the residual water on the walls of the water storage chamber 113, thereby drying out the residual water in the water tank 11 and improving drying efficiency.

[0069] In this embodiment, the drain outlet 112 is arranged at the bottom of the box body 111, and the drain outlet 112 is connected to the water storage chamber 113, so that the water in the water storage chamber 113 can be discharged through the drain outlet 112, and the pumping component 20 can pump out as much water as possible from the water tank 11, thereby improving the drainage efficiency.

[0070] Combine Figures 4 to 6 as well as Figure 8As shown, in some embodiments, the drainage system 10 for a fresh air humidifier further includes an air guide wheel 40. The air guide wheel 40 is disposed at the top opening of the housing 111. A portion of the air guide wheel 40 is located within the water storage chamber 113. The air guide wheel 40 can guide the hot air at the top opening into the interior of the water storage chamber 113.

[0071] In this embodiment, the air guide wheel 40 is disposed at the top opening of the cabinet body 111, with a portion of the air guide wheel 40 located within the water storage chamber 113. The air guide wheel 40 can guide the flow direction of the hot air within the cabinet body 111, directing the hot air from the top opening into the interior of the water storage chamber 113. This increases the contact area between the hot air and the wall of the water storage chamber 113, improving the drying effect, and helps to form a stable air path, thereby improving the smoothness of the hot air flow within the cabinet body 111.

[0072] Combine Figures 4 to 6 as well as Figure 8 As shown, in some embodiments, the air guide wheel 40 includes a first support plate 41, a second support plate 42 and a plurality of air guide plates 43. The first support plate 41 and the second support plate 42 are arranged opposite to each other and spaced apart, and the first support plate 41 and the second support plate 42 are both connected to the box body 111. The plurality of air guide plates 43 are all located between the first support plate 41 and the second support plate 42. One end of the plurality of air guide plates 43 is connected to the first support plate 41, and the other end of the plurality of air guide plates 43 is connected to the second support plate 42. Along the circumference of the first support plate 41 and the second support plate 42, the plurality of air guide plates 43 are arranged in sequence and spaced apart. The length direction of the plurality of air guide plates 43 is the same as the length direction of the box body 111.

[0073] In this embodiment, the first support plate 41 and the second support plate 42 are arranged opposite each other and spaced apart, providing support for the installation of multiple air guide plates 43. Furthermore, the first support plate 41 and the second support plate 42 are both connected to the box body 111, so that the first support plate 41 and the second support plate 42 are installed on the box body 111, and the air guide wheel 40 is installed at the top opening of the box body 111.

[0074] In this embodiment, the plurality of wind guide plates 43 are all located between the first support plate 41 and the second support plate 42, that is, the first support plate 41 and the second support plate 42 are respectively located at both ends of the plurality of wind guide plates 43 to support the plurality of wind guide plates 43. One end of the plurality of wind guide plates 43 is connected to the first support plate 41, and the other end of the plurality of wind guide plates 43 is connected to the second support plate 42, so that the first support plate 41, the second support plate 42 and the plurality of wind guide plates 43 are connected to form the whole of the wind guide wheel 40 for guiding the wind, facilitating installation and improving the stability of the wind guide. Along the circumference of the first support plate 41 and the second support plate 42, the plurality of wind guide plates 43 are arranged in sequence at intervals, and the hot air is guided by the plurality of wind guide plates 43 so that the hot air can flow along the circumference of the wind guide wheel 40 (such as Figure 8 , as indicated by the arc-shaped dotted arrow on the outside of the guide wheel 40), to dry the residual water in the water tank 11.

[0075] In this embodiment, the length direction of the plurality of air guide plates 43 is the same as the length direction of the box body 111, which further increases the contact area between the hot air and the inner wall of the box body 111 and improves the drying effect.

[0076] Optionally, the wind guide wheel 40 further includes one or more annular reinforcement ribs. The annular reinforcement ribs are parallel to the first support plate 41 and the second support plate 42. The annular reinforcement ribs are connected to the plurality of wind guide plates 43 to improve the working stability of the plurality of wind guide plates 43.

[0077] Optionally, the drainage system 10 for the fresh air humidifier 50 further includes a first drive motor and a second drive motor. Both the first drive motor and the second drive motor are fixed to the housing 111. The drive end of the first drive motor is connected to the first support plate 41. The drive end of the second drive motor is connected to the second support plate 42. The first drive motor and the second drive motor are capable of driving the air guide wheel 40 to rotate.

[0078] In this embodiment, when the residual water in the water tank 11 is being dried, the air guide wheel 40 does not rotate to guide the flow of hot air. When the fresh air humidifier 50 is used to adjust the air humidity, the first drive motor and the second drive motor drive the air guide wheel 40 to rotate, thereby utilizing the water in the water storage chamber 113 to humidify the air.

[0079] Optionally, the drainage system 10 for the fresh air humidifier 50 further includes a drive motor. The drive motor is fixed to the housing 111. A drive end of the drive motor is connected to one of the first support plate 41 and the second support plate 42. The other of the first support plate 41 and the second support plate 42 is rotatably connected to the housing 111. This allows the air guide wheel 40 to rotate with a single drive motor, reducing costs.

[0080] Combine Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 8 As shown, in some embodiments, the hot air assembly 30 includes a heater 31 and a fan 32. The heater 31 is located on one side of the water tank 11 and is used to heat the air before it flows through the water tank 11. The fan 32 and the heater 31 are respectively arranged on opposite sides of the water tank 11, with the air intake of the fan 32 close to the water tank 11. The fan 32 is used to drive the air flow, so that the air heated by the heater 31 flows through the water tank 11, and the air flowing through the water tank 11 enters the fan 32 and is discharged from the exhaust port of the fan 32.

[0081] In this embodiment, the heater 31 is located on one side of the water tank 11. The heater 31 is used to heat the air before it flows through the water tank 11 to provide hot air for the drying process.

[0082] In this embodiment, the fan 32 and heater 31 are disposed on opposite sides of the water tank 11, with the air intake of the fan 32 positioned close to the water tank 11. This allows the fan 32 to drive air flow when in operation. Specifically, the fan 32 drives the air flow, causing the air to flow through the water tank 11 after being heated by the heater 31, thereby drying any residual water in the water tank 11. The air that has flowed through the water tank 11 then enters the fan 32 and is discharged from the fan 32 outlet, thereby drying any residual water in the water tank 11.

[0083] In this embodiment, the heater 31 and the fan 32 cooperate to dry the residual water in the water tank 11, thereby solving the problems of odor and bacteria caused by the deterioration of the residual water, extending the service life of the water tank 11, and improving the user experience.

Specifically, when the solenoid valve 13 is in an open state, the water inlet pipe 12 is in a conducting state, at which time, water can be added to the water tank 11. When the solenoid valve 13 is in a closed state, the water inlet pipe 12 is in a shutoff state, at which time, water cannot be added to the water tank 11. When the pumping component 20 pumps water and dries the residual water in the water tank 11, the solenoid valve 13 is in a closed state, that is, the addition of water to the water tank 11 is stopped, so that the water in the water tank 11 is drained smoothly.

[0091] Combine Figure 3 As shown, in some embodiments, the drainage system 10 for the fresh air humidifier 50 further includes a float level gauge 14 and a controller. The float level gauge 14 is disposed in the water tank 11 and is used to detect the water level within the water tank 11. The controller is electrically connected to the float level gauge 14, the pumping assembly 20, and the hot air assembly 30. The controller is used to control the operation of the pumping assembly 20 and the hot air assembly 30 based on the water level within the water tank 11 detected by the float level gauge 14.

[0092] In this embodiment, a float level gauge 14 is disposed in the water tank 11 , and the float level gauge 14 is used to detect the water level in the water tank 11 .

[0093] In this embodiment, the controller is electrically connected to the float level gauge 14, the pumping component 20 and the hot air component 30 respectively. The water level information in the water tank 11 detected by the float level gauge 14 can be sent to the controller, so that the controller can control the operation of the pumping component 20 and the hot air component 30 according to the water level in the water tank 11 detected by the float level gauge 14 to dry the residual water in the water tank 11.

[0094] For example, when the water level in the water tank 11 detected by the float level gauge 14 is higher than the target water level, it indicates that there is a large amount of water in the water tank 11. The controller controls the water pump 21 to operate to pump the water out of the water tank 11. When the water level in the water tank 11 detected by the float level gauge 14 is equal to or lower than the target water level, it indicates that most of the water in the water tank 11 has been pumped out, and only a small amount of water remains in the water tank 11. The controller controls the water pump 21 to stop operating and controls the hot air assembly 30 to operate. Figure 8The dotted arrows in the figure illustrate the primary air flow direction when drying the residual water in the water tank 11. The fan 32 operates to drive the air flow, causing the air heated by the heater 31 to flow through the water tank 11, thereby drying the residual water in the water tank 11. The air flowing out of the water tank 11 then enters the fan 32 and is discharged from the exhaust port of the fan 32, thereby drying the residual water in the water tank 11. Of course, after the air is heated by the heater 31, some of the heated air does not flow through the inner wall of the water tank 11, but flows directly toward the fan 32. This portion of heated air, when flowing through the water tank 11, also helps dry the residual water in the water tank 11.

[0095] In this example, the shutdown time of the hot air component 30 can be controlled by setting the operating time of the hot air component 30.

[0096] In this embodiment, the controller includes a chip with logical operation capabilities and a circuit corresponding to the chip, and the control center includes one or more signal input terminals and one or more signal output terminals. For example, the control center is a single-chip microcomputer system, which includes a certain type of single-chip microcomputer chip and a power supply circuit, crystal oscillator circuit, etc. corresponding to the single-chip microcomputer chip of the model, and the single-chip microcomputer system includes input terminals / output terminals directly connected to the pins of the single-chip microcomputer chip, and input terminals / output terminals indirectly connected to the pins of the single-chip microcomputer through a signal adapter (such as a relay); or the control center is a programmable logic controller (PLC) system, which includes a central processing unit (CPU) module, an analog input module, an analog output module, a digital input module, and a digital output module.

[0100] Combine Figure 1 、 Figure 2 、 Figure 4 and Figures 6 to 8As shown, in some embodiments, the housing 51 is provided with an air inlet 52 and an exhaust port 53 communicating with the installation space. The air entering the installation space from the air inlet 52 is heated by the hot air assembly 30 and flows through the water tank 11 before flowing out from the exhaust port 53.

[0101] In this embodiment, the housing 51 is provided with an air inlet 52 and an exhaust port 53 that communicate with the installation space, allowing air to enter the installation space through the air inlet 52 and to flow out of the installation space through the exhaust port 53. In actual use, the air entering the installation space through the air inlet 52 is heated by the hot air assembly 30 and flows through the water tank 11 before flowing out of the exhaust port 53, thereby achieving air flow and drying any residual water in the water tank 11.

[0102] Optionally, the fresh air humidifier 50 further includes a water pump bracket. The water pump bracket is disposed on the housing 51. The water pump bracket is connected to the water pump 21 and is used to support the water pump 21.
