Technical Field
[0001] This application relates to the field of insulation sleeve technology, and more specifically, to an insulation sleeve for air conditioners. Background Technology
[0002] Insulation sleeves for air conditioners are insulation components that wrap around the air conditioning ducts. They use insulation material to block heat exchange between the ducts and the outside environment, reducing heat loss and preventing condensation on the duct surface, thus saving energy and protecting the ducts.
[0003] In practical use, traditional insulation sleeves are prone to moisture infiltration due to poor sealing after installation, causing the insulation material to become damp and fail. At the same time, the installation process is cumbersome and affects work efficiency.
[0004] In view of this, this application proposes an insulation sleeve for air conditioners. Utility Model Content

[0020] The present application will be further described in detail below with reference to the accompanying drawings.
[0021] Reference Figures 1-3This application provides an air conditioner insulation sleeve, including a sponge insulation cylinder 1. A groove 2 is formed on the outer wall of the sponge insulation cylinder 1. A moisture-proof component 3 is provided around the periphery of the sponge insulation cylinder 1. An upper protective shell 4 is provided above the periphery of the sponge insulation cylinder 1. The moisture-proof component 3 includes an aluminum foil moisture-proof film 301 located around the periphery of the sponge insulation cylinder 1. A mesh 302 is adhered to the inner wall of the aluminum foil moisture-proof film 301. A non-adhesive 303 is adhered to the inner wall of the mesh 302. The non-adhesive 303 is adhered to the outer wall of the sponge insulation cylinder 1, with the non-adhesive 303 close to the sponge. One side of the inner wall of the insulation cylinder 1 is covered with adhesive paper 304. By using the slot 2 on the sponge insulation cylinder 1, the sponge insulation cylinder 1 can be directly placed on the air conditioning pipe. With the extra non-adhesive 303 and adhesive paper 304, the extra non-adhesive 303 is pasted onto the aluminum foil moisture-proof film 301, effectively sealing the slot 2. This not only secures the sponge insulation cylinder 1, but also uses the aluminum foil moisture-proof film 301 to block moisture, preventing moisture from seeping into the insulation cylinder, avoiding the insulation material from becoming damp and failing, and protecting the pipe from condensation corrosion. At the same time, the installation is simple and the operation is convenient.
[0022] A lower protective shell 5 is provided below the outer perimeter of the sponge insulation cylinder 1. Fixing components 6 are provided on both sides of the upper protective shell 4 and the lower protective shell 5. Anti-slip film 7 is adhered to the inner walls of both the upper and lower protective shells 4 and 5. The fixing components 6 include a first combined frame 601 fixedly connected to one side of the upper protective shell 4, and a second combined frame 603 corresponding to the first combined frame 601 fixedly connected to one side of the lower protective shell 5. A top strip 602 is fixedly connected to the lower side wall of the first combined frame 601, and a retaining strip 604 is fixedly connected to the upper end of the second combined frame 603. The top strip 602 is movably engaged with the retaining strip 604. The upper and lower protective shells 4 and 5 are securely fixed to the two pipes through the elastic snap-fit structure of the top strip 602 and the retaining strip 604. The anti-slip film 7 on the inner wall of the upper protective shell 4 further enhances the pressure on the pipes, effectively buffering pipe vibration, reducing friction between the pipe sleeves, preventing pipe displacement and wear caused by vibration, and extending the service life of the pipes and pipe sleeves.
[0023] Working principle: The operator uses the slot 2 on the sponge insulation cylinder 1 to slip the sponge insulation cylinder 1 onto the air conditioner duct, tears off the adhesive paper 304 on one side of the non-adhesive 303, wraps the sponge insulation cylinder 1 tightly, and sticks one side of the non-adhesive 303 onto the aluminum foil moisture-proof film 301, thereby sealing the slot 2 and securing the sponge insulation cylinder 1. The aluminum foil moisture-proof film 301 provides excellent moisture protection, preventing moisture from seeping into the interior of the sponge insulation cylinder 1 and reducing the service life of the sleeve. After the pipes are fitted with sleeves, the pipe vibration can easily cause the sleeves to rub against each other. It is necessary to fix the two sleeves together. The workers first cover the outer perimeter of the two sleeves with the upper protective shell 4. The anti-slip film 7 on the inner wall of the upper protective shell 4 firmly holds the two pipes together. Then, the lower protective shell 5 is placed under the outer perimeter of the two sleeves. The retaining strips 604 on the second combination frame 603 on both sides of the lower protective shell 5 contact the top strip 602 on the first combination frame 601. As the retaining strip 604 moves upward, it will open the top strip 602 and the first combination frame 601. Until the retaining strip 604 passes the top strip 602, the first combination frame 601 and the top strip 602 rebound, and the top strip 602 enters the interior of the retaining strip 604. After the top strip 602 and retaining strip 604 on both sides of the upper protective shell 4 and the lower protective shell 5 are fixed, the upper protective shell 4 and the lower protective shell 5 firmly fix the two pipes to prevent vibration and friction from affecting the service life and to prevent loosening.
