Description

Technical Field

[0001] This utility model relates to the field of air purification technology, and in particular to a normal and epidemic-switching exhaust structure. Background Technology

They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0022] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "setting," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0023] Example 1: As shown in the figure, the present invention includes a ventilation device 1, an air inlet 2 and an air outlet located on the ventilation device 1. There are two air inlets 2, and each of the two air inlets 2 is provided with a filter channel 3 and a conversion channel 4. An opening and closing component is provided at the conversion channel 4. The opening and closing component is located inside the ventilation device 1 and can close or open the conversion channel 4.

[0024] The opening and closing assembly includes a sealing plate 6 and an opening and closing mechanism connected to the sealing plate 6. The opening and closing mechanism can drive the sealing plate 6 to close or open the conversion channel 4. The conversion channel 4 has a sealing port 9 that communicates with one of the air inlets 2, and the sealing plate 6 can be tightly connected to the sealing port 9.

[0025] Example 2: As shown in the figure, this utility model includes a ventilation device 1, an air inlet 2 and an air outlet located on the ventilation device 1. Two air inlets 2 are provided, each with a filter channel 3 and a conversion channel 4. An opening and closing assembly is provided at the conversion channel 4, located inside the ventilation device 1. The opening and closing assembly can close or open the conversion channel 4. Specifically, the opening and closing assembly includes a sealing plate 6 and an opening and closing mechanism connected to the sealing plate 6. The opening and closing mechanism can drive the sealing plate 6 to close or open the conversion channel 4. A sealing port 9 is provided at the conversion channel 4, communicating with one of the air inlets 2. The sealing plate 6 can be tightly connected to the sealing port 9.

[0026] The opening and closing mechanism includes an electric push rod 7, one end of which is connected to the ventilation device 1, and the other end of which is connected to the sealing plate 6. In this example, the opening and closing mechanism also includes a crossbeam 8 fixedly connected to the ventilation device 1, with one end of the electric push rod 7 mounted on the crossbeam 8. Specifically, in this example, two sets of electric push rods 7 are preferably provided, with both ends of the two electric push rods 7 hinged between the sealing plate 6 and the crossbeam 8, respectively. In this example, a connecting lug 11 is fixedly connected to the side of the sealing plate 6, and the free end of the electric push rod 7 is hinged to the connecting lug 11. The electric push rod 7 is used to drive the sealing plate 6 to slide back and forth outside the sealing opening 9.

[0028] The preferred working method of this utility model is as follows:

[0029] A. During normal work hours:

[0030] During normal operation, the sealing plate 6 of the conversion channel 4 is open, and the air discharged from the filter flows out quickly directly from the conversion channel 4 due to its own resistance.

[0031] B. During the pandemic working conditions:

[0032] Control commands are transmitted to the interior of the enclosure via an aviation connector. The electric push rod 7 executes the push command. When the sealing plate 6 reaches the predetermined position, the limit switch sends a feedback signal to the control unit, causing it to issue a stop command to the electric push rod 7. At this point, a sealing strip exists between the sealing plate 6 and the sealing port 9, achieving zero leakage in the conversion channel 4. The gas then needs to overcome the pressure of the high-efficiency filter to enter the enclosure and exit from the exhaust port.

[0033] This utility model, through the setting of the opening and closing components, switches between the conductive filter channel and the conversion channel, thereby realizing the conversion between the two working conditions of normal and epidemic modes. During an epidemic, it can be quickly connected and converted into an epidemic exhaust system, ensuring the stable operation of the air conditioning and ventilation system in the epidemic prevention functional area. It realizes the low energy consumption and low cost operation of the "normal and epidemic combined" air conditioning system, and has good application and promotion prospects.

[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
