Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, specifically to a filter assembly for the air intake channel of a wall-mounted air conditioner. Background Technology

[0002] An air conditioner, also known as an air conditioning unit, consists of four parts: a refrigeration (heating) circulation system, an air circulation and ventilation system, an electrical control system, and a housing. It is a small air conditioning unit that maintains a certain temperature, humidity, airflow speed, cleanliness, and freshness of the air in the regulated space.

[0003] Currently, in the application of air conditioning wall-mounted units, in order to prevent dust or foreign objects from entering the air conditioning unit through the air intake channel, a filter structure is often installed in the channel. However, most existing filter structures are fixed to the inside of the channel with bolts, which is not only difficult to disassemble and maintain, affecting cleaning, but also extremely inconvenient to install, greatly affecting the performance of the filter components. Utility Model Content

[0004] The purpose of this invention is to provide a filter assembly for the air intake channel of a wall-mounted air conditioner. By incorporating a baffle ring, support ring, pull handle, stop block, positioning post, and positioning groove, the support ring can be pushed into the air intake channel and abut against the baffle ring. Then, the positioning post can extend out of the positioning block and engage with the positioning groove, thereby locking the support ring securely within the air intake channel. Conversely, pulling the pull handle allows the positioning post to exit the positioning groove, thus pulling the support ring out of the air intake channel. This enables quick assembly and disassembly of the support ring, making operation simple and convenient. It also facilitates maintenance and replacement of the filter screen and activated carbon layer, greatly improving the filter assembly's performance and addressing the aforementioned shortcomings in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a filter assembly for the air intake channel of a wall-mounted air conditioner, comprising:

[0006] An air inlet channel is provided, with a fixed ring fixedly connected inside. An elastic component is connected to the side wall of the fixed ring. A retaining ring is connected to one end of the elastic component relative to the fixed ring. A support ring is installed on the side wall of the retaining ring.

[0007] The support ring has symmetrically arranged filter screens on both sides inside, and an activated carbon layer is arranged in the middle of the support ring between the two filter screens.

[0008] The support ring is symmetrically provided with positioning blocks at both ends on one side of the retaining ring. Each of the two positioning blocks has a retractable positioning post at its outer end. The air inlet channel has symmetrically provided positioning grooves facing the positioning posts on both sides inside.

[0009] Preferably, the positioning block has a cavity inside, and a second spring is fixedly connected to one end of the cavity relative to the positioning post. One end of the second spring is connected to a stop block, which is fixedly connected to the positioning post. A pull handle is connected through the end of the positioning block relative to the positioning post, and one end of the pull handle passes through the second spring and is fixedly connected to the stop block.

[0010] Preferably, the support ring is symmetrically provided with T-shaped sliders at both ends on one side of the positioning block, and the retaining ring is symmetrically provided with two T-shaped grooves that match the T-shaped sliders on the side near the support ring, and both T-shaped grooves have openings at their ends.

[0011] Preferably, the elastic component includes a plurality of first springs arranged in a ring array on the sidewall of the fixed ring, wherein one end of the first spring is fixedly connected to the retaining ring relative to the fixed ring.

[0012] Preferably, a limiting rod is connected through the fixed ring and the first spring, and one end of the limiting rod is fixedly connected to the retaining ring.

[0013] Preferably, the baffle ring is provided with limit blocks symmetrically at both ends, and the air inlet channel is provided with limit grooves matching the limit blocks on both sides of the interior.

[0014] Preferably, the end of the air inlet channel is provided with a mounting plate, and the side wall of the mounting plate is provided with multiple mounting holes.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] By incorporating a retaining ring, support ring, pull handle, stop block, positioning post, and positioning groove, the support ring can be pushed into the air inlet channel and abut against the retaining ring. Then, the positioning post can extend out of the positioning block and insert into the positioning groove, thereby locking the support ring in place within the air inlet channel. Conversely, pulling the pull handle will disengage the positioning post from the positioning groove, allowing the support ring to be pulled out of the air inlet channel. This enables quick assembly and disassembly of the support ring, making operation simple and convenient. It also facilitates the maintenance and replacement of the filter screen and activated carbon layer, greatly improving the performance of the filter assembly.

[0017] By setting a T-shaped slider, an opening, and a T-shaped groove between the support ring and the retaining ring, the support ring can be further reinforced by the limiting engagement of the T-shaped slider and the T-shaped groove, thereby greatly enhancing the stability of the support ring in the air inlet channel.

[0018] By setting multiple sets of first springs and limiting rods between the fixed ring and the retaining ring, when disassembling, once the locking of the support ring is released, the elastic rebound of the multiple sets of first springs can push the retaining ring, making it easier for the support ring to be moved out of the air inlet channel, thus greatly improving the convenience of disassembling and assembling the filter assembly.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figures 1-4 The air intake duct filter assembly of the wall-mounted air conditioner shown includes:

[0028] An air inlet channel 1 is provided, with a fixed ring 2 fixedly connected inside the air inlet channel 1. An elastic component is connected to the side wall of the fixed ring 2. A retaining ring 5 is connected to one end of the elastic component relative to the fixed ring 2. A support ring 8 is installed on the side wall of the retaining ring 5.

[0029] An installation plate is provided at the end of the air inlet channel 1, and the side wall of the installation plate is provided with multiple installation holes.

[0030] The support ring 8 has symmetrically arranged filters 9 on both sides inside, and an activated carbon layer 10 is arranged in the middle of the support ring 8 between the two filters 9. Based on this, dust and foreign objects can be intercepted by the filters 9, and the activated carbon layer 10 can further purify bacteria and viruses in the air.

[0031] The support ring 8 is symmetrically provided with positioning blocks 11 at both ends on one side of the retaining ring 5. The outer ends of the two positioning blocks 11 are provided with retractable positioning posts 14. The air inlet channel 1 is symmetrically provided with positioning grooves 15 facing the positioning posts 14 on both sides inside.

[0032] The positioning block 11 has a cavity inside. A second spring 12 is fixedly connected to one end of the cavity relative to the positioning post 14. A stop block 13 is connected to one end of the second spring 12. The stop block 13 is fixedly connected to the positioning post 14. A pull handle 16 is connected through one end of the positioning block 11 relative to the positioning post 14. One end of the pull handle 16 passes through the second spring 12 and is fixedly connected to the stop block 13.

[0033] In use, the two handles 16 on the support ring 8 can be pulled, causing the handles 16 to slide the stop block 13 in the cavity and squeeze the second spring 12. Then, the stop block 13 can drive the positioning post 14 to retract into the positioning block 11. After that, the support ring 8 can be pushed into the air inlet channel 1 and made to abut against the stop ring 5. When the positioning post 14 moves to the positioning groove 15, under the rebound of the second spring 12, the stop block 13 can drive the positioning post 14 to reset, so that the positioning post 14 extends out of the positioning block 11 and is inserted into the positioning groove 15, thereby locking the support ring 8 in the air inlet channel 1. Conversely, by pulling the two handles 16 to make the positioning post 14 exit the positioning groove 15, the support ring 8 can be pulled out of the air inlet channel 1, thus realizing the quick disassembly and assembly of the support ring 8. The operation is simple and convenient, making it easy to maintain and replace the filter screen 9 and the activated carbon layer 10, and greatly improving the performance of the filter assembly.

[0034] The support ring 8 is symmetrically provided with T-shaped sliders 17 on one side of the positioning block 11. The retaining ring 5 is symmetrically provided with two T-shaped grooves 18 that match the T-shaped sliders 17 on the side close to the support ring 8, and the ends of the two T-shaped grooves 18 are provided with openings 19.

[0035] By inserting the two T-shaped sliders 17 on the support ring 8 into the two openings 19 on the retaining ring 5, and then rotating the support ring 8, the two T-shaped sliders 17 can rotate in the two T-shaped grooves 18 respectively. Under the limiting engagement of the T-shaped sliders 17 and the T-shaped grooves 18, the support ring 8 can be further limited and reinforced, thereby greatly enhancing the stability of the support ring 8 in the air inlet channel 1.

[0036] The elastic component includes a plurality of first springs 3 arranged in a ring array on the side wall of the fixed ring 2, and one end of the first spring 3 relative to the fixed ring 2 is fixedly connected to the retaining ring 5.

[0037] A limiting rod 4 is connected through the fixed ring 2 and the first spring 3, and one end of the limiting rod 4 is fixedly connected to the retaining ring 5. Based on this, the first spring 3 can be supported and limited by the limiting rod 4.

[0038] Limiting blocks 6 are symmetrically arranged at both ends of the baffle ring 5, and limiting grooves 7 matching the limiting blocks 6 are opened on both sides of the air inlet channel 1. Based on this, by setting the limiting blocks 6 and the limiting grooves 7, the baffle ring 5 can drive the limiting blocks 6 to slide within the limiting grooves 7, thereby greatly ensuring the stability of the baffle ring 5 when it moves.

[0039] By setting multiple sets of first springs 3 and limiting rods 4 between the fixed ring 2 and the retaining ring 5, when the support ring 8 is pushed into the air inlet channel 1, the support ring 8 can drive the retaining ring 5 to squeeze the multiple sets of first springs 3 and limiting rods 4. Then the support ring 8 can be locked and fixed in the air inlet channel 1. When disassembling, once the locking is released, the retaining ring 5 can push the support ring 8 under the elastic rebound of the multiple sets of first springs 3, so that the support ring 8 can be moved out of the air inlet channel 1 more easily, which greatly improves the convenience of disassembling and assembling the filter assembly.

[0040] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
