Description

Technical Field

[0001] This utility model relates to the technical field of air filtration devices, specifically a heating, ventilation, and air conditioning (HVAC) air supply dust removal device. Background Technology

[0002] A complete air conditioning system consists of several filtration mechanisms, and the filter is one of the commonly used filtration components in air filtration. The filter is usually set in a frame, and then the frame is fixed to the air filtration channel with bolts. The structure is simple, easy to use, and can play a good filtration role. It has no defects in its use. During use, the filter will accumulate a lot of dust and impurities and needs to be replaced frequently. However, the replacement process requires disassembling and assembling the bolts on the frame. When there are many filters to be replaced, disassembling and assembling the bolts is a tedious process. Frequent disassembly and assembly of the bolts can also cause the bolt connections to loosen and create gaps, making maintenance inconvenient. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a dust removal device for HVAC air supply, which solves the problem that existing air conditioning air filtration systems require the disassembly and reassembly of a large number of bolts when replacing the filter, which is time-consuming, labor-intensive, and can lead to loose bolt connections.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a heating, ventilation and air conditioning air supply and dust removal device, including an outer frame and an inner frame, an opening on one side of the outer frame, the inner frame passing through the opening and inserted into the interior of the outer frame, a fixing mechanism on one side of the outer frame, a plurality of connecting bolts on the outer frame, and a filter screen installed in the inner frame.

[0005] Preferably, the fixing mechanism includes a stop block inserted into the opening, one end of the stop block contacting the side wall of the inner frame and the other end having a fixing strip, a pair of insert blocks on the outer wall of the fixing strip, the pair of insert blocks being inserted into the outer frame, a pair of fixing plates on the outer frame, a pair of movable plates movably connected to one end of the pair of fixing plates, a handle and a fixing ball respectively on the upper and lower walls of the movable plates, a slot being opened in the fixing strip, three elastic rubber strips being provided on the inner wall of the slot, and the fixing ball being inserted into the slot.

[0006] Preferably, the inner wall of the outer frame is provided with three limiting plates, and the outer wall of the inner frame is provided with three sliding grooves, which are respectively fitted onto the outside of the three limiting plates.

[0007] Preferably, a number of screws are provided between the fixing plate and the outer frame.

[0008] Beneficial effects

[0009] This utility model provides a dust removal device for HVAC air supply, which has the following beneficial effects:

[0010] 1. The filter screen is installed in the outer frame by inserting it into the inner frame, which is convenient for disassembly and assembly. When in use, simply pull the handle and pull the fixing ball at the bottom of the movable plate out of the slot to remove the fixing strip and the stop block from the outer frame. Then pull out the inner frame to achieve quick replacement. No need to tighten the bolts, disassembly and assembly are simple.

[0011] 2. The fixing ball is a spherical structure, which makes it easy to insert into the slot. The three elastic rubber strips in the slot can hold the fixing ball in the slot and prevent it from loosening and falling out of the slot. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution: a heating, ventilation and air conditioning air supply and dust removal device, including an outer frame 1 and an inner frame 3. The outer frame 1 has an opening on one side, and the inner frame 3 is inserted into the outer frame 1 through the opening. The outer frame 1 has a fixing mechanism on one side, and the outer frame 1 has several connecting bolts 2. A filter screen 4 is installed in the inner frame 3.

[0019] A slot is provided in the outer frame 1 at the opening for inserting the plug 13 on the fixing strip 8. This insertion method is a conventional technical means. The slot and the plug 13 can be matched structurally, so there is no need to describe the structure of the slot and the insertion method in detail.

[0020] The filter 4 is fixed inside the inner frame 3. The fixing method is a conventional technical means. When replacing, the inner frame 3 and the filter 4 are replaced at the same time.
