Description

Technical Field

[0001] This utility model relates to the field of duct deformation technology, specifically a reinforcing structure to prevent duct deformation. Background Technology

[0002] Ventilation ducts are hollow pipes used for ventilation, mostly round or square. The sheets, profiles, and other main finished materials used in the fabrication and installation of ventilation ducts should comply with the design and relevant current national standards, and should be accompanied by a certificate of conformity from the manufacturer. Materials should be inspected upon arrival at the site according to current national standards. When the duct wall thickness is insufficient or the material selection is inappropriate, it is often necessary to add a reinforcing structure inside the duct to prevent deformation during use.

[0003] While the anti-deformation reinforcement structures for air ducts currently on the market can effectively prevent duct deformation, they often make it inconvenient to replace the filters in actual use. The filters are typically installed using multiple screws and nuts, significantly impacting replacement efficiency. Furthermore, the presence of harmful gases in the air, if not filtered and inhaled, can lead to a range of health problems. Utility Model Content

[0004] The purpose of this invention is to provide a reinforced structure to prevent duct deformation, thereby solving the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A reinforced structure to prevent duct deformation includes a ventilation duct, one side of which is provided with a disassembly assembly for disassembling a filter screen, and the interior of which is provided with a filter assembly for filtering odors in the air. The disassembly assembly includes a filter screen installed on one side of the ventilation duct. A connecting plate is fixedly connected to one side of the filter screen. A groove is formed on one side of the connecting plate. A guide rod is fixedly connected to the top of the groove. One end of the guide rod is fixedly connected to the bottom of the groove. A backing plate is slidably connected to the outer wall of the guide rod. A spring is fixedly connected to the top of the backing plate on the side near the guide rod. The filter screen can be disassembled through the disassembly assembly, facilitating the replacement and cleaning of the filter screen.

[0006] Based on the above technical solutions, the present invention also provides the following optional technical solutions; In one alternative: one end of the spring is fixedly connected to the inner top of the connecting plate, a pull block is fixedly connected to one side of the abutment, and a locking block is fixedly connected to the bottom of the abutment.

[0007] In one alternative: a hole is provided on one side of the ventilation duct, and a slot is provided at the bottom of the hole; the filter screen can be effectively fixed by the cooperation between the locking block and the slot.

[0008] In one alternative: the filter assembly includes two fans fixedly mounted on one side of the ventilation duct and symmetrically mounted with respect to the center line of the ventilation duct.

[0009] In one alternative: a first filter shell is fixedly installed inside the ventilation duct, and a second filter shell is also fixedly installed inside the ventilation duct away from the first filter shell; the filter assembly can effectively absorb odors and harmful gases in the air, preventing them from being inhaled into the human body.

[0010] In one alternative: the ventilation duct is fixedly connected to a fixing rod, and the number of fixing rods is three, which are evenly installed inside the ventilation duct; the fixing rods can effectively support the inside of the ventilation duct and prevent the ventilation duct from deforming.

[0011] In one alternative: activated carbon is placed inside the first filter housing, and bamboo fiber is placed inside the second filter housing.

[0012] In one alternative: the number of disassembly components is two, and they are installed symmetrically along the center line of the ventilation duct.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the pull block drives the abutment plate to move, the guide rod guides it, the abutment plate drives the locking block to move, and the abutment plate drives the spring to retract. By removing the locking block and the abutment plate from the hole, the function of disassembling and installing the filter screen is achieved, which greatly facilitates the replacement and maintenance of the filter screen by the staff.

[0014] 2. In this utility model, the fan drives the air from the outer wall into the ventilation pipe. The activated carbon in the first filter shell filters out odors, toxic gases, ammonia, formaldehyde and other harmful gases in the air. The bamboo fiber inside the second filter shell controls the humidity in the air and performs secondary filtration, thus achieving the function of purifying the air and preventing the human body from inhaling too much harmful gas and causing physical discomfort.

[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Example 1 Please see Figures 1-3 This utility model provides a technical solution: a reinforced structure to prevent the deformation of the air duct, including a ventilation duct 1, a disassembly assembly 3 for disassembling the filter screen on one side of the ventilation duct 1, and a filter assembly 2 for filtering odors in the air inside the ventilation duct 1. The ventilation duct 1 is internally fixedly connected with three fixing rods 4, which are evenly installed inside the ventilation duct 1. The three fixing rods 4 can effectively prevent the ventilation duct 1 from deforming.

[0020] Example 2 Please see Figure 2 and Figure 3 The disassembly assembly 3 includes a filter screen 301 installed on one side of the ventilation duct 1. A connecting plate 302 is fixedly connected to one side of the filter screen 301. A groove is provided on one side of the connecting plate 302. A guide rod 303 is fixedly connected to the top of the groove. One end of the guide rod 303 is fixedly connected to the bottom of the groove. A stop plate 306 is slidably connected to the outer wall of the guide rod 303. A spring 304 is fixedly connected to the top of the stop plate 306 on the side near the guide rod 303. One end of the spring 304 is fixedly connected to the inner top of the connecting plate 302, a pull block 305 is fixedly connected to one side of the abutment plate 306, and a locking block 307 is fixedly connected to the bottom of the abutment plate 306. A hole is provided on one side of the ventilation pipe 1, and a slot 309 is provided at the bottom of the hole; The number of disassembly components 3 is two, and they are installed symmetrically along the center line of ventilation duct 1; When the filter screen 301 needs to be replaced or cleaned, the operator pulls the pull block 305, which moves the abutment plate 306. Guided by the guide rod 303, the abutment plate 306 moves the locking block 307, causing it to move out of the slot 309. The abutment plate 306 then retracts the spring 304. The operator operates both disassembly components 3 simultaneously, removing the locking block 307 and the abutment plate 306 from the hole. This facilitates the replacement and cleaning of the filter screen 301. When installation is required, the operator places the abutment plate 306 and the locking block 307 into the hole and pushes them inward. Once the locking block 307 enters the slot 309, the spring 304 moves the abutment plate 306, which in turn moves the locking block 307, engaging it with the slot 309. This greatly facilitates the maintenance of the filter screen 301.

[0021] Example 3 Please see Figure 4 The filter assembly 2 includes two fans 201 fixedly installed on one side of the ventilation duct 1 and installed symmetrically with respect to the center line of the ventilation duct 1. A first filter shell 202 is fixedly installed inside the ventilation duct 1, and a second filter shell 203 is also fixedly installed inside the ventilation duct 1 away from the first filter shell 202. The first filter housing 202 contains activated carbon, and the second filter housing 203 contains bamboo fiber. When indoor ventilation is needed, the fan 201 is turned on, and the fan 201 drives the air from the outside wall into the ventilation duct 1. When the air comes into contact with the first filter shell 202, the activated carbon in the first filter shell 202 filters out odors, toxic gases, ammonia, formaldehyde and other harmful gases in the air. When the filtered air passes through the second filter shell 203, the bamboo fiber inside the second filter shell 203 controls the humidity in the air. At the same time, the bamboo fiber can also be antibacterial and mildew-proof, and filter harmful gases in the air a second time.

[0022] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
