Technical Field

[0001] The utility model relates to the technical field of ventilation devices, in particular to an air-conditioning ventilation device. Background Art

[0002] In large buildings, most of them use central air conditioning to adjust the environment inside the building. Most of the existing central air conditioners supply air through pipes and fan coils, but central air conditioners are mostly used in summer and winter. In spring and autumn, due to long-term non-use, a lot of dust may accumulate in the pipes, so it is necessary to clean the dust in the pipes regularly. Since the pipe openings are mostly installed on the top of the room and the pipe openings are vertically downward, when cleaning the dust, the dust in the pipe may fall directly, thereby affecting the cleaning personnel under the pipe, making cleaning more inconvenient.

[0003] To this end, the utility model provides an air conditioning and ventilation device. Utility Model Content

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figures 1 to 4The utility model provides a technical solution: an air conditioning and ventilation device, comprising a ventilation duct 1, a heat preservation sleeve 2 is installed around the ventilation duct 1, the heat preservation sleeve 2 comprises an upper mounting plate 201 and a lower mounting plate 203, heat preservation cotton 204 is installed on the relative inner sides of the upper mounting plate 201 and the lower mounting plate 203, a filter plate 3 is installed at one end of the ventilation duct 1, a baffle 4 is installed on the side of the filter plate 3 away from the ventilation duct 1, a scraper rod 7 is installed in the ventilation duct 1, and the scraper rod 7 corresponds to the filter plate 3.

[0022] In this embodiment, the upper mounting plate 201 and the lower mounting plate 203 are both C-shaped structures, and multiple mounting blocks 202 are fixed at the ends of the upper mounting plate 201 and the lower mounting plate 203. A fixing bolt is installed between two contacting mounting blocks 202, and the upper mounting plate 201 and the lower mounting plate 203 are fixedly connected by fixing bolts. The upper mounting plate 201 and the lower mounting plate 203 are both fixedly connected to the thermal insulation cotton 204, and a superimposed sheet 205 is fixedly connected near the connection between the upper mounting plate 201 and the lower mounting plate 203. The superimposed sheet 205 and the thermal insulation cotton 204 are an integrated structure, and the superimposed sheet 205 and the thermal insulation cotton 204 are both made of thermal insulation material.

[0023] Specifically, the thermal insulation cotton 204 can insulate the ventilation duct 1, and the two overlapping sheets 205 stacked together can insulate the joints. When the thermal insulation cotton 204 is damaged somewhere, the upper mounting plate 201 and the lower mounting plate 203 at that place can be directly removed, so that the damaged part can be replaced to ensure the thermal insulation effect.

[0024] The ventilation duct 1 is fixedly connected to the filter plate 3 by bolts, a plurality of connecting blocks 5 are fixed on the filter plate 3, the connecting blocks 5 are fixedly connected to the baffle 4, the scraper rod 7 is a circular structure, the scraper rod 7 contacts the inner wall of the ventilation duct 1, and a plurality of connecting rods 6 are fixed between the scraper rod 7 and the filter plate 3.

[0025] Specifically, when the ventilation duct 1 blows air, the wind passes through the filter plate 3 and is blocked by the baffle 4, thereby preventing the air-conditioning wind from blowing directly downward. The air-conditioning wind blows out to the surroundings through the gap between the filter plate 3 and the baffle 4.

[0026] When the ventilation duct 1 is not used for a long time, it is necessary to clean the inside of the ventilation duct 1. At this time, you only need to remove the filter plate 3 and then pull the filter plate 3 downward so that the filter plate 3 drives the scraper rod 7 to scrape the inner wall of the ventilation duct 1 through the connecting rod 6. The dust on the inner wall of the ventilation duct 1 can be scraped off, and the dust falls on the filter plate 3 and the baffle 4, which can prevent the dust from falling on the cleaning personnel, making cleaning more convenient.

[0027] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
