Description

Technical Field

[0001] This utility model relates to a detachable dustproof HVAC control device, and more particularly to a detachable dustproof HVAC control device. Background Technology

[0002] Intelligent HVAC control devices are key equipment for ensuring building comfort and energy conservation, and their core controllers are usually installed in protective enclosures. However, in order to meet the heat dissipation requirements of the electronic components inside the enclosure, the enclosure must be designed with necessary ventilation structures, which provides a channel for external dust to enter.

[0003] In complex environments such as industrial plants, airborne dust particles continuously penetrate the enclosure through ventilation openings. Long-term accumulation of dust on the surfaces and internal components of the control equipment can easily lead to problems such as poor circuit contact and reduced heat dissipation, affecting not only control accuracy but also, in severe cases, causing equipment malfunctions and short circuits, thus shortening the overall lifespan.

[0004] In existing technologies, dustproofing methods for protective boxes mostly involve fixed filters or simple seals, which have drawbacks such as inconvenient disassembly and cleaning, making it difficult for users to maintain regular maintenance, resulting in a rapid decline in dustproofing effectiveness over time. Therefore, there is an urgent need for an intelligent control device solution that is easy to maintain and can provide long-lasting and effective dustproofing. Utility Model Content

[0005] The purpose of this utility model is to provide a detachable dustproof HVAC control device. By setting up an independent dustproof mechanism consisting of a first fixing component, a dustproof net and a second fixing component, and optimizing its connection and fixing method, the device ensures excellent dustproof effect while realizing quick disassembly and convenient maintenance of dustproof components.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A detachable dustproof HVAC control device includes a cabinet and a cabinet door pivotally connected together. The opening of the cabinet is provided with a dustproof mechanism. The dustproof mechanism includes a dustproof net, a first fixing member fixed to the upper end of the dustproof net, and a second fixing member fixed to the lower end of the dustproof net.

[0007] A further solution: The first fixing member includes two coaxial and spaced-apart placement rods, a support rod parallel to the placement rods, and an elastic rope connecting the dustproof net, the placement rods, and the support rod.

[0008] A further solution: the two ends of the placement rod extend through the side wall of the cabinet.

[0009] A further solution: the two ends of the placement rod have telescopic structures.

[0010] A further solution: The second fastener includes a clip connected to the bottom of the dustproof net and a clip plate magnetically attracted to the clip, the clip plate being fixedly connected to the bottom of the cabinet.

[0011] A further solution includes a level located at the top of the cabinet. The level includes a guide groove fixed to the top of the cabinet, a limiting rod fixed to both ends of the guide groove, and a ball located between the limiting rod and the guide groove. The contact surface between the guide groove and the ball has an arc-shaped cross-section. The ball can slide back and forth in a restricted manner on the guide groove.

[0012] A further solution: The dustproof net includes a mesh screen, flexible strips fixed on the left and right sides of the mesh screen, and reinforcing strips fixed at the top and bottom ends of the mesh screen.

[0013] A further option: the distance between the two placement rods is 1 / 3 to 1 / 2 of the width of the dustproof net.

[0014] Compared with the prior art, the beneficial effects of this utility model are: The detachable dustproof HVAC control device provided in this solution improves the maintainability and dustproof reliability of the equipment. Specifically, through the cooperation of a first fixing component consisting of a placement rod, a support rod, and an elastic rope, and a second fixing component consisting of a magnetic clamp and a clamping plate, the dustproof net can be quickly and securely installed and automatically tensioned, and can also be easily removed as a whole for cleaning, completely solving the defects of existing fixed dustproof structures that are inconvenient to disassemble and difficult to maintain.

[0015] Furthermore, by making the placement rods exposed or telescopic, and combining this with a specific spacing between the two placement rods, a physical channel and operating space are provided for the extraction path of the dustproof net, making the entire disassembly and assembly process simple and intuitive, requiring no special tools. This design greatly simplifies the maintenance process while ensuring the stability of the dustproof net support.

[0016] In summary, this device effectively overcomes the risks of poor heat dissipation and poor contact caused by dust accumulation in traditional protective boxes during long-term use. Through an easy-to-implement mechanical structure, it achieves a balance between dustproof performance and ease of maintenance, thereby ensuring the long-term stable operation and service life of the HVAC control system.

Detailed Implementation

[0018] 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.

[0019] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] Please see Figure 1-5 This embodiment discloses a detachable dustproof HVAC control device, including a cabinet 1 and a cabinet door 2 pivotally connected together. A dustproof mechanism is provided at the opening of the cabinet 1. The dustproof mechanism includes a dustproof net 3, a first fixing member 4 fixed to the upper end of the dustproof net 3, and a second fixing member 5 fixed to the lower end of the dustproof net 3. By providing a dustproof mechanism consisting of the dustproof net 3, the first fixing member 4, and the second fixing member 5 at the opening of the cabinet 1, effective dustproof protection for the core components of the control device is achieved, while also ensuring that the dustproof components are easy to disassemble and clean, laying the foundation for convenient subsequent maintenance.

[0021] Furthermore, the first fixing component 4 includes two coaxially spaced placement rods 41, a support rod 42 parallel to the placement rods 41, and an elastic rope 43 connecting the dustproof net 3, the placement rods 41, and the support rod 42. Through the first fixing component 4, composed of the placement rods 41, the support rods 42, and the elastic rope 43, automatic tensioning and buffering protection of the dustproof net 3 are achieved. The elastic rope 43 can continuously provide tension, ensuring that the dustproof net 3 is always flat and wrinkle-free, thereby guaranteeing optimal dustproof and observation effects; at the same time, the elastic connection avoids rigid pulling on the dustproof net 3 during installation and disassembly, extending its service life.

[0022] Furthermore, through holes 421 are provided at intervals on the support pole 42. One end of the elastic rope 43 passes through the through hole 421 and is connected to it, so that it can be accurately connected to the tough strip at the upper end of the dustproof net, thereby effectively transmitting the tensile rebound force of the elastic rope to the entire dustproof net surface.

[0023] Furthermore, the two ends of the placement rod 41 extend through the side wall of the cabinet 1. By placing the two ends of the placement rod 41 outside the cabinet 1, the user can operate the placement rod 41 directly from the outside without opening the cabinet door 2 or going inside the cabinet 1, thereby quickly completing the overall disassembly and assembly of the dustproof mechanism and greatly improving maintenance efficiency.

[0024] Furthermore, the placement rod 41 has telescopic structures 44 at both ends. This design, by configuring the telescopic structures 44 at both ends of the placement rod 41, provides installation tolerance and adaptability. The effective length of the placement rod 41 can be finely adjusted to accommodate cabinets 1 of different sizes or slightly off-center installation positions, enhancing the versatility of this dustproof mechanism.

[0025] Furthermore, the second fastener 5 includes a locking block 51 connected to the bottom of the dustproof mesh 3 and a locking plate 52 magnetically attracted to the locking block 51. The locking plate 52 is fixedly connected to the bottom of the cabinet 1. The second fastener 5, consisting of the locking block 51 and the locking plate 52, achieves a fast and reliable fixing and unlocking mechanism. Utilizing the magnetic principle, one-click fixing and separation of the bottom of the dustproof mesh 3 can be achieved, making operation very convenient; at the same time, magnetic attraction ensures the stability of the fixation, preventing loosening due to vibration or other reasons.

[0026] Furthermore, it also includes a level 6 located at the top of the cabinet 1. The level 6 includes a guide groove 61 fixed to the top of the cabinet 1, limiting rods 62 fixed to both ends of the guide groove 61, and a ball 63 located between the limiting rods 62 and the guide groove 61. The contact surface between the guide groove 61 and the ball 63 has an arc-shaped cross-section. The ball 63 can slide back and forth in a restricted manner on the guide groove 61. The level 6, which includes the guide groove 61, the limiting rods 62, and the ball 63, provides a built-in installation calibration tool. Installers can quickly and intuitively judge and adjust the levelness of the cabinet 1 by using the sliding of the ball 63 within the guide groove 61.

[0027] Furthermore, the dustproof net 3 includes a mesh 31, flexible strips 32 fixed to the left and right sides of the mesh 31, and reinforcing strips 33 fixed to the top and bottom ends of the mesh 31. Through this composite structure comprising the mesh 31, flexible strips 32, and reinforcing strips 33, the overall structural strength and morphological stability of the dustproof net 3 are enhanced. The flexible strips 32 prevent the sides of the mesh 31 from curling, ensuring a tight fit between the edges of the dustproof net 3 and the cabinet 1; the reinforcing strips 33 protect the mesh 31 from tearing at the fixing points, improving the durability of the entire dustproof mechanism.

[0028] Furthermore, metal sheets are attached to the upper and lower sides inside the cabinet 1, providing reliable magnetic adsorption points for the support rod at the top of the dustproof mechanism and the magnetic suction block at the bottom. This enables the dustproof net 3 to be quickly positioned and fixed without tools, while also enhancing its overall stability in the working state and preventing displacement due to vibration or other factors.

[0029] Furthermore, the distance between the two placement rods 41 is 1 / 3 to 1 / 2 of the width of the dustproof net 3, achieving a balance between ease of disassembly and structural stability. This distance ensures that the middle of the dustproof net 3 has sufficient folding space to be easily pulled out between the two placement rods 41, while also ensuring that the placement rods 41 provide stable and uniform support for the upper part of the dustproof net 3.

[0030] When it is necessary to disassemble, clean, or replace the dustproof net 3, first release the second fixing part 5 at the bottom to separate the locking block 51 from the locking plate 52; then, the dustproof net 3 will naturally sag under its own weight and the rebound force of the elastic rope 43. At this time, press or pull out the placement rod 41 with telescopic structure 44 at both ends from the outside of the cabinet 1, and the dustproof net 3, the first fixing part 4, and the second fixing part 5 can be taken out as a whole through the gap between the two placement rods 41. When installing, simply reverse the operation: first place the support rod 42 at the top of the dustproof net 3 into the cabinet, then reset and lock the placement rod 41, and finally attach the locking block 51 at the bottom to the locking plate 52 to complete the installation, and the dustproof net 3 will automatically tighten and flatten under the tension of the elastic rope 43.

[0031] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0032] Therefore, the above description is only a preferred embodiment of this application and is not intended to limit the scope of this application; that is, all equivalent modifications made in accordance with the scope of the claims of this application shall be within the protection scope of the claims of this application.
