Abstract
Description
Technical Field
[0001] This utility model relates to the field of air conditioning technology for construction machinery, specifically to an air exchange and filtration device for air conditioning in construction machinery. Background Technology
[0002] Due to my country's climate characteristics, air conditioning is used in most parts of the country, especially in construction machinery vehicles used in harsh outdoor weather. A search revealed a publicly available technology, CN203364386U, which discloses an air exchange and filtration device for air conditioning in construction machinery. This invention includes a filter and a housing. The housing contains two filters: an external circulation filter and an internal circulation filter. The external circulation filter, internal circulation filter, fresh air damper, and housing wall form a closed chamber. A heat exchanger is connected below the internal circulation filter. The opening of the external circulation filter connects to the outside. The advantages of this invention are that it extends the service life of the air conditioner, facilitates the replacement of related components, and is cost-effective. This invention can be widely applied to manufacturers of construction machinery vehicles used in outdoor applications.
[0003] In summary, although the above case solved the air conditioning ventilation filtration problem, the internal circulation filter in the above solution is installed on the outer shell of the ventilation device by a snap-fit method. Due to the insufficient strength of the snap-fit method, it may not be able to withstand repeated disassembly, affecting the product life. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing an air exchange and filtration device for air conditioning in engineering machinery. This solves the problem that the snap-fit method mentioned in the background technology may not be strong enough to withstand repeated disassembly, thus affecting the product's lifespan.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an air exchange and filtration device for air conditioning of engineering machinery, comprising a shell structure, wherein an internal circulation structure is installed on the surface of the shell structure;
[0006] The shell structure includes an outer shell as the main body, and a through groove is provided on the surface of the outer shell. At the same time, a magnet strip is laid and fixedly installed above the surface of the through groove.
[0007] The outer shell has a connecting hole on the top surface for easy connection of the bearing, and the inner ring of the connecting bearing is rotatably connected to one end of the connecting rod, while the other end of the connecting rod is fixedly installed to the rotating connecting plate.
[0008] By adopting the above technical solution, the connecting bearings are used to achieve a matching connection.
[0009] Preferably, a convex circular block is fixedly installed on the surface of the rotating connecting plate, and the convex circular blocks are arranged symmetrically.
[0010] By adopting the above technical solution, the convex circular block is designed to achieve a rotational compression and limiting effect.
[0011] Preferably, the internal circulation structure includes an internal circulation filter body as the main body, and a concave block is fixedly installed on the surface of the internal circulation filter body, while a limiting block is fixedly installed on the inner side of the concave block. A through frame is fixedly installed above the surface of the internal circulation filter body, and an adsorption strip is fixedly installed at the bottom of the through frame.
[0012] By adopting the above technical solution, the adsorption strips are designed to achieve adsorption and positioning.
[0013] Preferably, the internal circulation filter body is equipped with a filter element that is easy to install and remove quickly, and multiple filter elements can be used.
[0014] By adopting the above technical solution, the filter element can achieve the function of filtering and interception.
[0015] Preferably, the connecting rod and the rotating connecting plate are connected in an "L" shape.
[0016] By adopting the above technical solution, the connecting rod is set to serve as a matching connection at one end.
[0017] Preferably, there are four recessed blocks, and the recessed blocks are arranged symmetrically.
[0018] By adopting the above technical solution, the recessed block serves to fix the installation on the inside.
[0019] Compared with the prior art, the beneficial effects of this utility model are: the air exchange and filtration device for air conditioning in engineering machinery,
[0020] (1) This case solves the problem that the snap-fit method may not be able to withstand multiple disassemblies and affect the product life by setting the shell structure. The set magnetic strip, connecting bearing, connecting rod, rotating connecting plate and convex block not only play a role in the initial adsorption limit of the inner circulation filter body, but also play a role in the secondary rotation and locking limit of the inner circulation filter body by the connecting rod, rotating connecting plate and convex block, which facilitates the quick installation and disassembly of the inner circulation filter body.
[0021] (2) By setting an internal circulation structure, the above problems are solved. After the internal circulation filter body performs initial adsorption and positioning, the rotating connecting plate and the convex block rotate inside the concave block to rotate and lock the rotating connecting plate, thus preventing the internal circulation filter body from easily shifting or loosening.

Detailed Implementation
[0029] 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.
[0030] Please see Figure 1-6 This utility model provides a technical solution: an air exchange and filtration device for air conditioning in engineering machinery, such as... Figure 1 and Figure 2 As shown, it includes a shell structure 1, which includes an outer shell 101 as the main body, and a through groove 102 is provided on the surface of the outer shell 101. At the same time, a magnet strip 103 is laid and fixedly installed above the surface of the through groove 102.
[0031] The outer shell 101 adopts the outer shell setting in the prior art document. When the outer shell setting in the prior art document is used, the outer shell 101 is opened and the internal components are installed and fixed. The magnet strip 103 adopts the existing technology component setting. When the existing technology component setting is used, it can effectively play the role of contact adsorption limit.
[0032] like Figure 3 As shown, in the above solution, a connection hole for easy connection of bearing 104 is provided on the upper surface of the outer shell 101, and the inner ring of the connecting bearing 104 is rotatably connected to one end of the connecting rod 105. At the same time, the other end of the connecting rod 105 is fixedly installed to the rotating connecting plate 106. The connection shape of the connecting rod 105 and the rotating connecting plate 106 is set in an "L" structure. When the connection shape of the two is set in an "L" structure, it not only reflects the fixed installation of the two, but also reflects the synchronous force-bearing rotation adjustment of the two. Furthermore, when the connection shape of the two is set in an "L" structure, it effectively reflects the practicality and operability of the two.
[0033] Furthermore, a convex block 107 is fixedly installed on the surface of the rotating connecting plate 106, and the convex block 107 is arranged symmetrically.
[0034] The rotating connecting plate 106 is provided in four pieces, and a set of convex round blocks 107 are fixedly installed on the surface of each rotating connecting plate 106. The convex round blocks 107 are used to limit the rotation of the rotating connecting plate 106.
[0035] like Figure 4 , Figure 5 and Figure 6 As shown, an inner circulation structure 2 is installed on the surface of the shell structure 1. The inner circulation structure 2 includes an inner circulation filter body 201 as the main body, and a recess 202 is fixedly installed on the surface of the inner circulation filter body 201. There are 4 recesses 202, and the recesses 202 are arranged symmetrically. The number of the above-mentioned components is the same as the number of rotating connecting plates 106. By using the same number of components as rotating connecting plates 106, the rotation of rotating connecting plates 106 is limited. At the same time, a limit block 203 is fixedly installed on the inner side of the recess 202. A through frame 204 is fixedly installed on the upper surface of the inner circulation filter body 201, and an adsorption strip 205 is fixedly installed on the bottom of the through frame 204.
[0036] Among them, the internal circulation filter body 201 is also installed and set up using the internal circulation filter in the comparative document. When the internal circulation filter in the comparative document is installed and set up, it can effectively perform internal gas exchange.
[0037] Furthermore, the internal circulation filter body 201 is equipped with a filter element 206 that is easy to install and disassemble quickly, and multiple filter elements 206 can be used.
[0038] The internal circulation filter body 201 is equipped with a filter element 206, which facilitates the quick disassembly, installation and replacement of the filter element 206.
[0039] In the above scheme, after manually holding the inner circulation filter body 201 and connecting it with the through groove 102, the magnet strip 103 and the adsorption strip 205 are attracted. Then, the rotating connecting plate 106 is manually rotated so that the convex block 107 presses against the limiting block 203 and limits the rotation of the rotating connecting plate 106. After the rotating connecting plate 106 is installed in the limited position, the outer circulation filter is installed above the inner circulation filter body 201 through the through groove 102. The outer circulation filter is also set and installed using the components in the comparative document, thereby facilitating the internal and external gas exchange.
