Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, and in particular to a dustproof sealing plug for the air outlet of an indoor air conditioning unit. Background Technology

[0002] After production, air conditioner indoor units undergo multiple stages, including packaging, warehousing, and transportation, before finally reaching the user for installation. During this process, the air outlet of the indoor unit is exposed or partially exposed. Although the product is packaged, fine dust, particles, insects, or other foreign objects can still enter the internal air ducts and heat exchanger through the gaps in the air outlet grille.

[0003] In existing technologies, ordinary plastic film or foam blocks are often used to simply cover or stuff the air outlet. This method has poor sealing effect and is prone to displacement or falling off during transportation vibration, with limited dust prevention effect. Alternatively, operators can use tape to directly stick it on the air outlet grille. This method easily leaves adhesive residue on the panel after the tape is removed, affecting the appearance of the product. Moreover, cleaning the adhesive residue is time-consuming and laborious, resulting in a poor user experience.

[0004] Therefore, there is a need for a dustproof device that can effectively seal, is secure, and is easy to install and disassemble. Utility Model Content

[0005] The main purpose of this utility model is to provide a dustproof sealing plug for the air outlet of an indoor air conditioner, which aims to solve the problem that existing dustproof devices during air conditioner transportation are difficult to balance effective sealing and easy disassembly.

[0006] To achieve the above objectives, the dustproof sealing plug for the air outlet of an indoor air conditioning unit proposed in this utility model includes:

[0007] plug;

[0008] A sealing lip is provided on the side of the plug body facing the air outlet of the indoor unit of the air conditioner, and the sealing lip extends circumferentially along the plug body;

[0009] The snap-fit ​​structure includes a snap hook, which is disposed on the side wall of the plug and faces the air outlet of the indoor unit of the air conditioner. The plug is connected to the air outlet of the indoor unit of the air conditioner through the snap hook.

[0010] An operating handle is provided on the plug body on the side away from the air outlet of the indoor unit of the air conditioner, and the operating handle is spaced apart from the buckle structure.

[0011] Preferably, there are multiple snap-fit ​​structures, which are symmetrically distributed along the sidewall of the plug body. Each snap-fit ​​structure has a cutting groove at one end near the plug body, and the cutting groove is a preset weak line set along the thickness direction of the snap-fit ​​structure.

[0012] Preferably, the snap-fit ​​structure further includes an elastic arm, one end of which is connected to the plug body, and the other end of which is connected to the hook. The cutting groove is located at the connection between the elastic arm and the plug body.

[0013] Preferably, the hook further includes a guide ramp, which is disposed on one end of the hook facing the plug.

[0014] Preferably, the plug further includes a support frame, which is disposed on the side of the plug away from the air outlet of the indoor unit of the air conditioner, and the support frame is connected to the operating handle.

[0015] This invention features a sealing lip that surrounds the bottom of the plug and fits tightly against the air outlet panel or grille, preventing dust, insects, and other contaminants from entering the air conditioning duct.

[0026] like Figures 1-3 As shown, this utility model proposes a dustproof sealing plug 1000 for the air outlet of an indoor air conditioner, comprising: a plug body 100; a sealing lip 200, the sealing lip 200 being disposed on the side of the plug body 100 facing the air outlet of the indoor air conditioner, the sealing lip 200 extending circumferentially along the plug body 100; a snap-fit ​​structure 300, the snap-fit ​​structure 300 including a hook 310, the hook 310 being disposed on the side wall of the plug body 100 facing the air outlet of the indoor air conditioner, the plug body 100 being connected to the air outlet of the indoor air conditioner through the hook 310; and an operating handle 400, the operating handle 400 being disposed on the side of the plug body 100 away from the air outlet of the indoor air conditioner, and the operating handle 400 being spaced apart from the snap-fit ​​structure 300.

[0027] In this invention, the plug 100 is made of a soft material, including but not limited to EPE pearl cotton, EVA foam, silicone or soft plastic (TPU / TPE) plate structure, which has a certain amount of compression and resilience. The sealing lip 200 is a sealing element with one or more rings of flexible material around the plug 100, forming an annular protrusion structure. The cross-section of the sealing lip 200 is semi-circular. When the plug 100 is pressed to the air outlet of the indoor unit of the air conditioner, the sealing lip 200 will fully contact the air outlet panel to achieve a circumferential sealing effect and effectively block external dust. A snap-fit ​​structure 300 is also provided around the periphery of the plug body 100. The snap-fit ​​structure 300 is spaced apart from the sealing lip 200. The end of the snap-fit ​​structure 300 is provided with a hook 310, which is used to snap onto the back of the grille strip or the inner side of the frame of the air outlet of the indoor unit of the air conditioner, providing mechanical fixation and preventing it from falling off during transportation vibration. There are multiple snap-fit ​​structures 300, which can be adapted to the grille strip of different models. When using the plug 1000 during transportation or storage, align the dustproof sealing plug 1000 with the air outlet of the indoor unit of the air conditioner, press the operating handle 400 with both hands, so that the hook 310 passes over the air outlet frame or embeds into the grille gap, hooking the inner structure of the air outlet frame or embedded in the grille gap to achieve a firm fixation; the sealing lip 200 simultaneously fits against the edge of the air outlet to complete the seal. After transportation or storage, the user can hold the operating handle 400 and pull it outwards to release the hook 310, allowing the sealing plug to be completely removed without any residue or damage to the air conditioning vent.

[0028] In this embodiment, the sealing lip 200 consists of a ring with a cross-sectional height of 1.5 mm. There are four snap-fit ​​structures 300 on each side, totaling eight on both sides, spaced apart. An operating handle 400 is integrally formed on the side of the plug 100 facing away from the air outlet of the indoor unit (i.e., the exposed surface). The operating handle 400 is a ring-shaped protrusion located in the center of the plug 100, spatially spaced from the surrounding snap-fit ​​structures 300, facilitating gripping by the user or operator.

[0029] In one embodiment, there are multiple snap-fit ​​structures 300, which are symmetrically distributed along the side wall of the plug body 100. Each snap-fit ​​structure 300 has a cutting groove 311 at one end near the plug body 100. The cutting groove 311 is a preset weak line set along the thickness direction of the snap-fit ​​structure 300.

[0030] In this embodiment, a cutting groove 311 is provided at the connection between the snap-fit ​​structure 300 and the plug 100. The cutting groove 311 can be a V-shaped or U-shaped groove, forming a preset weak line. During the manufacturing or installation process, the operator can use manual or automated tools to manually break off or cut off the unnecessary snap-fit ​​structure 300 along the cutting groove 311 according to the shape or structure of the air outlet of the target air conditioner model. This increases the applicable scenarios, reduces mold development costs, and improves installation efficiency.

[0031] In one embodiment, the snap-fit ​​structure 300 further includes an elastic arm 320, one end of which is connected to the plug body 100, and the other end of which is connected to the hook 310. The cutting groove 311 is located at the connection between the elastic arm 320 and the plug body 100.

[0032] In this embodiment, each snap-fit ​​structure 300 includes an integrally formed elastic arm 320 and a snap hook. One end of the elastic arm 320 is connected to the side wall of the plug 100, and the other end is fixedly connected to the snap hook 310. The snap hook 310 extends toward the air outlet of the indoor unit of the air conditioner. At the connection between the elastic arm 320 and the plug 100, a cutting groove 311 is provided along the thickness direction of the elastic arm 320 to provide an operator with the means to remove the snap hook 310 that is not compatible with the air outlet structure of the air conditioner.

[0033] In one embodiment, the hook 310 further includes a guide ramp 312, which is disposed on one end of the hook 310 facing the plug 100.

[0034] In this embodiment, the free end of the hook 310 is provided with a guide slope 312. The guide slope 312 is located at the end of the hook 310 near the plug body 100, and is used to guide the hook 310 to slide over the edge of the air outlet frame during installation, thereby reducing assembly resistance.

[0035] In one embodiment, the plug body 100 further includes a support frame 500, which is disposed on the side of the plug body 100 away from the air outlet of the indoor unit of the air conditioner, and the support frame 500 is connected to the operating handle 400.

[0036] In this embodiment, the support frame 500 is made of rigid plastic (such as PP or ABS), and is cross-shaped or ring-shaped. It is formed by secondary injection molding of the plug body 100. The operating handle 400 is fixedly installed on the support frame 500 on the side away from the plug body 100. The direct connection between the operating handle 400 and the support frame 500 ensures that the force when pulling out the plug body 100 is borne by the high-strength frame, avoiding the risk of tearing caused by the force acting directly on the plug body 100 made of soft material. By setting the support frame 500, the overall rigidity and bending deformation resistance of the plug body 100 are significantly enhanced, making it suitable for air conditioning indoor units with large-area air outlets. It ensures the uniform distribution of sealing pressure and provides sufficient structural support force when the user or operator pulls it out, preventing the handle from collapsing.

[0037] This invention features a sealing lip that surrounds the bottom of the plug and fits tightly against the air outlet panel or grille, preventing dust, insects, and other contaminants from entering the air conditioning duct. A snap-fit ​​structure ensures a secure lock, effectively resisting vibrations and impacts during transport. Furthermore, a handle allows operators to easily remove the plug from the air conditioner, improving efficiency on the production line and during installation. The supporting frame significantly enhances the overall rigidity and resistance to bending deformation of the plug, ensuring uniform distribution of sealing pressure and extending the product's lifespan.

[0038] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
