Description

Technical Field

[0001] This utility model relates to a small household appliance, and more particularly to a dual-duct pet air purifier. Background Technology

[0002] Traditional air purifiers often use a single air intake method (such as bottom / side / top air intake), resulting in limited air intake volume, which is difficult to meet the purification needs of large spaces. Although some devices adopt a multi-faceted air intake design, when the air intake is set at the top and bottom to increase the air intake volume, dust suction problems are likely to occur, allowing dust and other impurities to directly invade the filtration system.

[0003] Existing filtration systems often rely on a single, commonly used filter. When dust is drawn in through the air inlet, a large amount of impurities quickly reduces the filter's efficiency and shortens its lifespan. In addition, replacing commonly used filters is costly, and frequent replacements increase the burden on users. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a dual-duct pet air purifier.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A dual-duct pet air purifier includes a central support frame with upper and lower air outlet chambers. An impeller driven by a motor is installed within each air outlet chamber. An upper filter assembly and a lower filter assembly are respectively installed on the upper and lower sides of the central support frame. Both the upper and lower filter assemblies include filter brackets. A removable primary filter is installed on the side of the filter bracket away from the impeller, and a removable secondary filter is installed on the side away from the impeller. An upper air inlet cover with an upper air inlet is installed above the upper filter assembly, and a lower air inlet base with a lower air inlet is installed below the lower filter assembly.

[0007] It also includes a housing, the sidewall of which is provided with an air outlet grille corresponding to the air outlet of the air outlet cavity. The housing covers the central support, the upper filter assembly and the lower filter assembly. The upper air inlet cover is installed on the top of the housing and the lower air inlet base is installed on the bottom of the housing.

[0008] The housing includes a U-shaped main housing and a side cover that is detachably installed at the U-shaped opening of the main housing. The main housing and the side cover are covered with the grid. The side cover is installed on one side of the primary filter and the secondary filter in the direction of disassembly and assembly.

[0009] The primary filter includes a mesh support covered with non-woven fabric.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0022] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.

[0023] The following describes some embodiments of the present invention with reference to the accompanying drawings.

[0024] Reference Figure 1-4 A dual-duct pet air purifier includes a central support 1, with upper and lower air outlet chambers 2 inside the central support 1. An impeller 3 driven by a motor is installed inside the air outlet chamber 2. An upper filter assembly 4 and a lower filter assembly 5 are respectively installed on the upper and lower sides of the central support 1. Both the upper and lower filter assemblies 4 and 5 include filter brackets 6. A removable primary filter 7 is installed on the side of the filter bracket 6 away from the impeller 3, and a removable secondary filter 8 is installed on the side away from the impeller 3. An upper air inlet cover 10 with an upper air inlet 9 is installed above the upper filter assembly 4, and a lower air inlet base 12 with a lower air inlet 11 is installed below the lower filter assembly 5. By providing air inlets at the bottom and top of the device, the air intake is increased. The primary filter 7 intercepts hair, large dust particles, and other debris as preliminary filtration, reducing the filtration load on the secondary filter 8 and extending its service life.

[0025] The primary filter 7 can only perform preliminary filtration; deeper filtration requires the secondary filter 8. In this application, the lower air inlet 11 is provided at the bottom of the lower air inlet base 12. Therefore, when the device is working, dust, hair, and other impurities on the bottom surface are easily sucked in. The main function of the primary filter 7 is to filter these impurities, eliminating the need for filtration by the secondary filter 8, thereby reducing the filtration load on the secondary filter 8 and increasing its service life.

[0026] The primary filter 7 includes a mesh support 16 covered with non-woven fabric. The non-woven fabric can be replaced periodically, and the secondary filter 8 can be directly replaced. The maintenance cost of only replacing the non-woven fabric is extremely low.

[0027] In order to increase the air intake volume, some products on the market, in order to avoid the bottom air intake causing a decrease in filter life, usually choose to add a long strip-shaped air intake on the side wall of the air intake cover. The longer the air intake, the greater the air intake volume. However, the longer the air intake, the greater the overall height of the product, thereby increasing the storage and transportation costs. In this application, the upper air intake 9 can cover the top surface of the upper air intake cover 10, and the lower air intake 11 can cover the bottom of the lower air intake base 12, which is sufficient to meet the high air intake volume requirements of most air purifiers.

[0028] In this product, the motor unit can be a single motor, with the motor's rotating shaft extending from both the top and bottom ends of the motor (e.g., ...). Figure 3 As shown in A), it is connected to two impellers 3 respectively, or it can be two motors, each motor driving one impeller 3, without interfering with each other.

[0029] This product also includes a housing 13. The side wall of the housing 13 is provided with an air outlet grille 22 corresponding to the air outlet of the air outlet cavity 2. The housing 13 covers the central support 1, the upper filter assembly 4 and the lower filter assembly 5. The upper air inlet cover 10 is installed on the top of the housing 13 and the lower air inlet base 12 is installed on the bottom of the housing 13. The housing 13, the lower air inlet base 12 and the upper air inlet cover 10 together form the outer shell of this product, thereby improving the aesthetics of the product.

[0030] Furthermore, the outer side of the housing 13 is configured as a grid structure corresponding to the air outlet grille 22 (the grid structure is not ventilated), so that the overall shape of the housing 13 is consistent and the aesthetics are improved.

[0031] The housing 13 includes a U-shaped main housing 14 and a side cover 15 detachably installed at the U-shaped opening of the main housing 14. The main housing 14 and the side cover 15 are covered with the grid mesh. The side cover 15 is installed on one side of the primary filter 7 and the secondary filter 8 in the direction of disassembly and assembly, while the main housing 14 is installed on the other three sides (it can be fixed with screws to ensure that the installation firmness of the main housing 14 will not change after the side cover 15 is removed). When it is necessary to replace the non-woven fabric, the primary filter 7 can be removed and replaced simply by removing the side cover 15. The operation is simple.

[0032] Both the upper filter assembly 4 and the lower filter assembly 5 are provided with a first insertion slot 17 and a second insertion slot 18. The primary filter 7 is inserted into the first insertion slot 17, and the secondary filter 8 is inserted into the second insertion slot 18.

[0033] In this embodiment, the upper filter assembly 4 and the lower filter assembly 5 are provided with air inlet holes 19 corresponding to the impeller 3 on the side near the impeller 3. After the external air enters through the air inlet, it is initially filtered by the primary filter 7, and then filtered a second time by the secondary filter 8. After entering the air outlet chamber 2 through the air inlet 19, it is finally discharged through the air outlet grille 22.

[0034] In this embodiment, the side wall of the upper air inlet cover 10 is provided with a plurality of first side air inlets 20 arranged thereon. The upper air inlet cover 10 is installed on the housing 13. In order to ensure the strength of the installation, the upper air inlet cover 10 needs to be provided with a certain length of flange. The first side air inlets 20 are provided without increasing the flange, so as to avoid increasing the height of the product.

[0035] Similarly, the side wall of the lower air inlet base 12 is provided with a plurality of second side air inlets, but in this embodiment, no second side air inlets are provided.

[0036] The lower air inlet base 12 is equipped with a support foot 21 at its bottom, which increases the distance between the bottom of the lower air inlet base 12 and the bottom surface, reduces the suction force on dust, hair and other impurities on the bottom surface, thereby reducing the entry of such impurities into the product and filtering them by the primary filter 7, thereby improving the service life of the primary filter 7 in the lower filter assembly 5.

[0037] Since the upper air inlet 9 of the upper air inlet cover 10 faces upwards, only impurities floating in the air can generally enter through the upper air inlet 9, such as PM2.5 in the air. However, the amount of such impurities is far less than the amount of impurities drawn in by the lower air inlet 11 of the lower air inlet base 12. Therefore, the replacement frequency of the non-woven fabric of the primary filter 7 in the upper filter assembly 4 can be less than the replacement frequency of the non-woven fabric of the primary filter 7 in the lower filter assembly 5. However, for users who keep pets, since pet shedding is a common phenomenon, there are often floating hairs in the air. The primary filter 7 of the upper filter assembly 4 can also be used to block these floating hairs. Therefore, the replacement frequency of the primary filter 7 of the upper filter assembly 4 will be higher.
