[0001] The utility model relates to the technical field of air treatment, in particular to an indoor air replacement device for a new energy building. Background Art

[0002] Indoor air replacement refers to the process of exchanging and replacing indoor air with external air through mechanical or natural ventilation in the indoor environment to improve indoor air quality. Through indoor air replacement, pollutants, odors and moisture accumulated in the room can be effectively removed, while fresh air is introduced into the room to improve the freshness and comfort of indoor air.

[0003] The Chinese patent "An indoor air replacement device for new energy buildings" authorization announcement number "CN 217900098U" installs a mounting ring at the interface on the rear side of the air replacement fan, and a filter element is movably installed on the inner side of the mounting ring. When the air is transported into the room, the dust and impurities in the air are filtered through the filter element, so that the purified air is transported into the room, which greatly increases its practicality.

[0004] The above application can achieve air filtering operation, but the filter element and the mounting ring are movably connected. When the air replacement fan is started, the airflow may cause a gap between the filter element and the mounting ring, so that some smaller impurities can pass through the gap into the room, affecting the air filtering effect.

[0005] Therefore, an indoor air replacement device for a new energy building is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] When implementing: Figure 1-5 As shown, an indoor air replacement device for a new energy building comprises: a mounting plate 1, an air replacement fan 2 is mounted on one side of the mounting plate 1, and a filter mechanism 3 is arranged on the other side of the air replacement fan 2; wherein the filter mechanism 3 comprises a mounting ring 301 mounted on the other side of the air replacement fan 2, a filter plate 302 is mounted on the inner wall of the mounting ring 301, a mounting groove 303 is provided at the other end of the mounting ring 301, a cylinder 304 distributed in an annular shape is fixedly connected to the inner wall of the mounting groove 303, a circular plate 305 is fixedly connected to the inner wall of the cylinder 304, two clamping rods 306 are slidably connected to the inner wall of the cylinder 304, a connecting rod 307 is hinged at one end of the clamping rod 306, the other ends of the two connecting rods 307 are hinged to one end of the circular plate 305, and a sealing assembly 308 is arranged on the inner wall of the mounting groove 303.

[0026] When installing the device, first install the mounting plate 1 at the desired position by nuts and bolts, then install the mounting plate 1 and the mounting ring 301 by nuts and bolts, after the installation is completed, put the filter plate 302 into the mounting groove 303, and the two clamping rods 306 are retracted in the cylinder 304 in the initial state, which does not affect the normal entry of the filter plate 302 into the mounting groove 303. When the circular plate 305 moves, it pushes the other end of the connecting rod 307 to move, and under the action of the connecting rod 307, the two clamping rods 306 are moved away from each other.

[0027] It should be noted that the air replacement fan 2 is a relatively mature device in the prior art and will not be described in detail here.

[0028] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the sealing assembly 308 includes an annular airbag 3085 fixedly connected to the inner wall of the mounting groove 303, the other end of the cylinder 304 is fixedly connected to an air storage box 3086, the inner wall of the air storage box 3086 is slidably connected to an extrusion plate 3087, one end of the circular plate 305 is fixedly connected to two round rods 3088, the other end of the round rods 3088 passes through the cylinder 304 and the air storage box 3086 in sequence and is fixedly connected to one side of the extrusion plate 3087, and a connecting pipe 3089 is provided between the air storage box 3086 and the annular airbag 3085.

[0029] When the device is in the initial state, the annular airbag 3085 is in a compressed state, and the air storage box 3086 is filled with gas. When the circular plate 305 moves, the round rod 3088 moves to push the extrusion plate 3087 to squeeze the gas in the air storage box 3086. After being squeezed, the gas enters the annular airbag 3085 through the connecting tube 3089. The connecting tube 3089 can undergo a slight deformation to expand the annular airbag 3085, thereby sealing the connection between the filter plate 302 and the mounting ring 301.

[0030] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the sealing assembly 308 also includes a fixed block 3081 fixedly connected to the upper end of the surface of the mounting ring 301, the inner wall of the fixed block 3081 is threadedly connected to a threaded rod 3082, the surface of the mounting ring 301 is slidably connected to a circular ring 3083, one end of the threaded rod 3082 passes through the fixed block 3081 and is rotatably connected to one end of the circular ring 3083, the other end of the circular plate 305 is fixedly connected to a moving rod 3084, the other end of the moving rod 3084 passes through the cylinder 304 and the mounting ring 301 in sequence and is fixedly connected to the other end of the circular ring 3083.

[0031] When the threaded rod 3082 is rotated, the circular ring 3083 moves to the side away from the air replacement fan 2, thereby driving the movable rod 3084 to move. When the movable rod 3084 moves, it pushes the circular plate 305 to move. A movable groove matching the movement of the movable rod 3084 is provided on the surface of the mounting ring 301. When the movable rod 3084 cannot be squeezed and moved, the installation and sealing of the filter plate 302 is completed.

[0032] like Figure 2 As shown, the surface of the filter plate 302 is provided with annular through grooves 3021, and the shape of the through grooves 3021 matches the shape of the air storage box 3086. There are four through grooves 3021, which is the same as the number of the air storage box 3086. The four through grooves 3021 are distributed in a cross shape. When the filter plate 302 is placed in the installation groove 303, the corresponding air storage box 3086 passes through the through grooves 3021.

[0033] like Figure 2 and Figure 4 As shown, the other end of the mounting ring 301 is clamped with a protective frame 309. The other end of the mounting ring 301 is provided with a clamping groove 3011.

[0034] The protection frame 309 consists of two protection rings and a protection plate. When installing the protection frame 309, the upper protection ring is inserted into the slot 3011. The shape of the slot 3011 matches the shape of the upper protection ring. The lower protection ring and the protection plate protect the through slot 3021 and the air storage box 3086.

[0035] like Figure 4 As shown, the other end of the threaded rod 3082 is fixedly connected to a knob, and the surface of the knob is provided with annularly distributed grooves. The staff can rotate the threaded rod 3082 by turning the knob, and the grooves can increase the friction when the staff turns the knob.

[0036] like Figure 3 As shown, the two ends of the air storage box 3086 are bent into an arc shape. Both ends of the inner wall of the through groove 3021 are bent into an arc shape, and the bending angle is the same as the bending angle of the two ends of the air storage box 3086.

[0037] When the utility model is in use, when using the device, first install the mounting plate 1 at the desired position, then install the air replacement fan 2 with the mounting plate 1, and install the mounting ring 301 with the air replacement fan 2. After the installation is completed, put the filter plate 302 into the mounting groove 303, and rotate the threaded rod 3082 to drive the ring 3083 to move, which drives the moving rod 3084 to move and push the circular plate 305. The movement of the circular plate 305 will push the other end of the connecting rod 307 and the circular rod 3088 to move synchronously. When the other end of the connecting rod 307 moves, it will push the two clamping rods 306 move away from each other and pass through the cylinder 304, so that the surface of the clamping rod 306 is in contact with one end of the filter plate 302 and pressed against the filter plate 302. At the same time, when the round rod 3088 moves, it will push the squeezing plate 3087 to move and squeeze the gas in the gas storage box 3086. After being squeezed, the gas will enter the annular airbag 3085 through the connecting pipe 3089, so that the annular airbag 3085 will expand, thereby sealing the connection between the filter plate 302 and the mounting ring 301. When the moving rod 3084 cannot be squeezed and moved, the installation and sealing of the filter plate 302 are completed.

[0038] When the device is used to replace indoor air, the air replacement fan 2 is started, and the outdoor air will enter the room through the filter plate 302 and the installation ring 301 in sequence to replace the indoor air.

[0039] 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.
