[0002] In some occasions with high requirements for environmental humidity (such as the microenvironment for preventive protection of cultural relics), humidity regulating devices are needed to regulate the environmental humidity. The humidity regulating device is a relatively common existing humidity regulating device. However, in the process of use, it is found that the existing purification and humidity regulating device has the following disadvantages: 1. The existing structure of the humidity regulator has no purification function and cannot filter substances such as PM2.5, VOC, and formaldehyde in the air, and cannot purify the air well; 2. The regulation channel is only a single channel, and the humidification channel and the dehumidification channel share the whole process, and the whole process uses a common channel, so the humidity regulation efficiency is low, the energy consumption is high, and a stable and clean microenvironment cannot be formed; 3. The existing structure layout is not reasonable enough, resulting in an insufficiently compact structure design.

[0003] Therefore, how to design a purification and humidity regulating device with channel switching that has a simpler and more compact structure design, can better purify the air, and can switch between the humidification channel and the dehumidification channel to achieve higher humidity regulation efficiency and lower energy consumption has become a technical problem to be solved by those skilled in the art.

[0005] To achieve the above object, the present utility model provides a purification and humidity regulating device with channel switching, including a housing, on which an air inlet and an air outlet are provided; it is characterized in that an air inlet chamber connected to the air inlet is arranged inside the housing; on the inner bottom surface of the air inlet chamber, a humidification air inlet and a dehumidification air inlet are arranged side by side, and a duct switching flap is hingedly connected between the humidification air inlet and the dehumidification air inlet so as to be vertically rotatable, and a driving structure is arranged in the housing corresponding to the duct switching flap and can drive the duct switching flap to flip and successively cover and seal the humidification air inlet and the dehumidification air inlet; a horizontally arranged humidification channel is connected and arranged corresponding to the humidification air inlet in the housing, and a humidification water inlet is arranged on the humidification channel; a horizontally arranged dehumidification channel is connected and arranged corresponding to the dehumidification air inlet in the housing; a condenser is further arranged in the housing, and the distal ends of the humidification channel and the dehumidification channel are respectively connected to the input end of the condenser, and the output end of the condenser is connected to the air outlet.

[0006] In this way, when the above device is working, when the driving structure drives the air duct switching flap to flip and cover and seal the humidification air inlet, the dehumidification air inlet is in an open state; after the air enters from the air inlet, it enters the air inlet chamber and then enters from the dehumidification air inlet, passes through the dehumidification channel and then is processed by the condenser, and is output from the air outlet, and the output air is humidity-adjusted. When the driving structure drives the air duct switching flap to flip and cover and seal the dehumidification air inlet, the humidification air inlet is in an open state; after the air enters from the air inlet, it enters the air inlet chamber and then enters from the humidification air inlet, passes through the humidification channel and then is processed by the condenser, and is output from the air outlet, and the output air is humidified.

Thus, it can better switch and use through the humidification channel and the dehumidification channel to achieve higher humidity adjustment efficiency and lower energy consumption.

[0008] As an optimization, an air inlet pipe and an air outlet pipe are respectively connected and provided on the air inlet and the air outlet on the housing.

[0009] In this way, by respectively connecting and providing an air inlet pipe and an air outlet pipe on the air inlet and the air outlet, the structural design is simpler and more reasonable, and it is more convenient to connect and use.

[0010] As an optimization, rectangular structure-designed relief grooves are respectively provided on two surfaces of the air duct switching flap, and the inner contour dimensions of the rectangular grooves are larger than the inner contour dimensions of the humidification air inlet and the dehumidification air inlet; and after the air duct switching flap covers the humidification air inlet, the humidification air inlet is located inside the inner contour of the relief groove; after the air duct switching flap covers the dehumidification air inlet, the dehumidification air inlet is located inside the inner contour of the relief groove.

[0011] In this way, the structural design of the air duct switching flap is simpler and more reasonable. By respectively providing rectangular structure-designed relief grooves on two surfaces of the air duct switching flap, and through the limitation of the contour dimensions of the relief grooves, after the air duct switching flap flips, the two surfaces of the air duct switching flap can better cover and seal the humidification air inlet and the dehumidification air inlet, so as to better complete the switching.

[0012] As an optimization, the driving structure includes a stepping motor, and the motor shaft of the stepping motor is in transmission connection with the air duct switching flap and can drive it to flip.

[0017] In this way, the structural design of the housing is more reasonable. By designing the upper housing and the lower housing, it is more convenient for processing and manufacturing. It is also more convenient for the distribution layout of the air inlet chamber, the humidification channel and the dehumidification channel; making the whole structural design more compact. Secondly, by designing the purification module, usually the purification module adopts a medium-efficiency HEPA + activated carbon + cold catalyst composite filter element. It can filter PM2.5, VOC, formaldehyde and other substances better, achieving the air purification function. And a power circulation fan is also provided, which can drive the air to circulate better and improve the efficiency. The air flow is regulated to pass through the purification module, and through channel switching, the air flow replenishes moisture through the humidification water surface, and then passes through the condensation channel for humidity regulation and control, and enters the microenvironment after reaching the set target humidity, and reciprocally regulates to make the microenvironment gradually approach the target humidity.

[0023] In this way, the length and horizontal area of ​​the humidification channel are made larger, thereby improving the humidification effect and efficiency when the airflow passes through. In addition, the design of the entire humidification channel and dehumidification channel is more reasonable.

At the same time, the flap position can be collected by designing a photoelectric switch, and the channel can be freely switched according to the working requirements of the instrument through hardware and software algorithms.

[0029] 4. When the humidification process starts: the channel airflow is driven by the internal circulation fan, and the airflow is regulated to pass through the purification module. Through channel switching, the airflow passes through the humidification water surface to replenish moisture, and then passes through the condensation channel for humidity adjustment and control, reaching the set target humidity to enter the microenvironment, and reciprocating regulation is performed to make the microenvironment gradually approach the target humidity;

[0030] 5. When the dehumidification process is started: The channel air flow is powered by the internal circulation fan, and the air flow is regulated to pass through the purification module. Through channel switching, the air flow directly passes through the condensation channel for humidity adjustment and control. When the set target humidity is reached, it enters the microenvironment and is reciprocally regulated to gradually approach the target humidity in the microenvironment; this process omits the air flow compensation process, which greatly facilitates the improvement of dehumidification efficiency.

[0031] 6. The condenser adopts a refrigerant copper tube fin structure, which increases the contact area between the air flow and the condenser, is conducive to heat exchange, quickly reaches the dew point temperature of the air flow, and achieves the humidity adjustment function.
