[0002] The main role of the fresh air conditioning system is to realize the circulation and ventilation between indoor air and outdoor air, and to realize the role of purifying air. The turbid indoor air is discharged to the outdoor through the fresh air system pipeline, and the indoor and outdoor air forms a pressure difference, completing the exchange of indoor and outdoor air, and achieving the purpose of fresh indoor air.

[0003] The fresh air conditioning introduces outdoor fresh air into the air conditioner, and discharges it into the room after purification. At the same time, the fresh air conditioning introduces indoor air into the fresh air conditioning through the indoor return air outlet, and discharges it to the outdoor through the exhaust air pipeline, so as to realize the exchange of indoor and outdoor air. In this exchange process, the filter device in the fresh air conditioning filters various impurities in the air. However, due to the installation environment of the fresh air conditioning, the installation methods are as follows: ceiling installation, floor installation, vertical wall installation and tripod auxiliary installation. The built-in filter device is not convenient to replace. If the filter device is not replaced for a long time, the purification efficiency will decrease, and it will be blocked, resulting in increased energy consumption.

[0004] Therefore, a new scheme is needed to solve this problem. INVENTION CONTENTS

[0024] As Figure 1 - Figure 5As shown, the four side walls of the shell 1 are fixedly connected with several ceiling mounting racks 2, the vertical hanging bolts are screwed into the ceiling mounting racks 2, the ceiling mounting mode is realized, the vertical wall mounting can be fixedly connected with the mounting seat on the outer wall of the shell 1, and the tripod auxiliary mounting needs to be first installed on the wall surface, is fixed on the tripod through the connecting metal piece arranged on the side wall of the shell 1 by the bolt and nut mode, the air return inlet 4 of the shell 1 is sequentially provided with a gasket 8, an adjusting base 7 and a filter 6 in sequence, the gasket 8, the adjusting base 7 and the filter 6 are all provided with openings communicated with the air return inlet 4, that is, the openings penetrate through the gasket 8, the adjusting base 7 and the filter 6, so that indoor air can enter the air return inlet 4, and the gasket 8 and the adjusting base 7 are fixedly connected on the shell 1 by bolts, that is, the bolts penetrate through the gasket 8 and the adjusting base 7 at the edges of the gasket 8 and the adjusting base 7 and are fixedly connected with the threaded holes on the shell 1 or through the nuts.

[0025] As Figure 1 - Figure 5As shown, the filter 6 is integrally tubular, and the inner circumferential wall is fixedly connected with a filter screen 601, which can be an activated carbon filter screen 601. The filter screen 601 and the filter device inside the casing 1 achieve a double-layer filtering effect, reduce the increase in energy consumption due to long-term non-replacement of the filter device, ensure the energy-saving effect of the fresh air conditioner, improve the filtering effect of the filter 6 on the return air, and ensure the stable opening of the sliding channel 9. The filter 6 has a sliding channel 9 penetrating the filter 6, which also penetrates the adjusting base 7 and the backing plate 8. When the backing plate 8, the adjusting base 7 and the filter 6 are fixedly connected to the casing 1, the sliding channels 9 on the backing plate 8, the adjusting base 7 and the filter 6 are mutually penetrated and aligned to form a straight slot. A rack 703 is slidably connected inside the sliding channel 9. The rack 703 is a straight rack 703, and the flat side thereof abuts against the inner wall of the sliding channel 9. The width of the rack 703 is less than the width of the sliding channel 9, so as to facilitate the engagement of the gear 706 with the rack 703. The adjusting base 7 has an adjusting groove 704 in communication with the sliding channel 9, which is used to place the gear 706. The gear 706 is engaged with the rack 703, and rotating the gear 706 can drive the rack 703 to slide in the sliding channel 9. The length of the rack 703 is equal to the sum of the lengths of the sliding channels 9 on the adjusting base 7 and the backing plate 8, and the width of the rack 703 is equal to the width of the sliding channel 9. The length of the rack 703 is set so that the rack 703 is completely retracted in the sliding channels 9 on the adjusting base 7 and the backing plate 8, and does not extend into the sliding channel 9 of the filter 6, so as to ensure that the filter 6 can be stably separated from the adjusting base 7, facilitating replacement. The width of the rack 703 is set mainly to improve the stability of the sliding of the rack 703, and to support and stabilize the filter 6 when the rack 703 is located in the sliding channel 9 of the filter 6.
