[0035] The technical solution of the present utility model will be further described below in conjunction with the embodiments and drawings.

[0036] Example

[0037] Since existing desktop range hoods do not pay attention to noise optimization, some desktop range hoods on the market will produce a lot of noise when running, affecting the user experience. Therefore, this application discloses a range hood purifier, referring to Figure 1-2The range purifier includes a housing 10, a first filter assembly 20, and an air induction assembly 30. An air inlet 11 is provided on the side of the housing 10, and an air outlet 12 is provided on the top of the housing 10. The first filter assembly 20 is mounted on the housing 10 and is positioned at the air inlet 11 to filter the oil smoke entering the housing 10. The air induction assembly 30 is mounted within the housing 10 and is used to draw external smoke into the housing 10 through the first filter assembly 20 at the air inlet 11 for filtration, and then exhaust it from the air outlet 12.

[0038] Specifically, refer to Figure 2 The air induction assembly 30 includes a volute 31, a wind wheel 33 and a fan. The volute 31 is mounted on the inner wall of the housing 10, wherein the volute 31 includes a front volute 311 and a rear volute 312, the front volute 311 and the rear volute 312 are fixedly connected, the motor 32 is mounted on the rear volute 312, and the wind wheel 33 is mounted on the output end of the motor 32. An air inlet 313 is provided on one side of the front volute 311, and the air inlet 313 is provided downstream of the first filter assembly 20. The tops of the front volute 311 and the rear volute 312 are surrounded by an air outlet 314, the size of which is adapted to the cross-section of the housing 10, and the air inlet 313 and the air outlet 314 are connected to form a guide air duct. The exhaust port 314 is connected to the air outlet 12, and the setting of the guide air duct allows the air flow to rise evenly. The size of the exhaust port 314 is the same as the cross-sectional size of the shell 10, avoiding turbulence due to sudden changes in the air port area, ensuring the effect of air intake and outlet, and reducing the noise caused by internal interference of the air flow.

[0039] In one embodiment of the present invention, referring to Figure 2 The air induced component 30 also includes a partition grille 34, which is installed at the air induced port 313 of the front volute 311. The partition grille 34 separates the fan and the first filter component 20, thereby avoiding interference between the first filter component 20 and the wind wheel 33, and at the same time avoiding the user touching the wind wheel 33 when replacing the first filter component 20.

[0040] Specifically, in one embodiment of the present invention, referring to Figure 3-4 The first filter assembly 20 includes a first filter housing 21, an air inlet grille 22, and a first composite filter screen 23. The first filter housing 21 is mounted on the air inlet 11 of the housing 10, the air inlet grille 22 is mounted on the first filter housing 21, and the first composite filter screen 23 is mounted between the front volute 311 and the air inlet grille 22, with the first composite filter screen 23 being closely attached to one side of the air inlet grille 22.

[0041] Preferably, in one embodiment of the present invention, the air inlet grille 22 is a porous layer supported by an alloy material, which is used to condense the high-temperature oil smoke to improve the oil smoke removal rate and extend the life of the subsequent first composite filter 23.

[0042] Preferably, in one embodiment of the present invention, referring to Figure 4 The first composite filter 23 includes a first filter layer 231, a second filter layer 232 and a third filter layer 233. Specifically, the first filter layer 231 is a filter, which is used to preliminarily filter particulate matter, tar, oil smoke, hair and other substances, pre-treat the airflow, and extend the life of the filtration system. The second filter layer 232 is a glass fiber layer, which is cut into a circular shape by glass fiber and is mainly used to absorb oil pollutants. The third filter layer 233 is a honeycomb carbon layer, which is made of plastic or alloy honeycomb glued with activated carbon and then cut into discs to reduce airflow resistance and purify volatile organic pollutants and odors in the airflow. The first composite filter 23 is made of a filter cut into a circular shape, glass fiber and honeycomb carbon, which are stacked together in order and then wrapped with glue. The air inlet grille 22 and the filter are also glued and fixed.

[0043] In one embodiment of the present invention, referring to Figure 2 The range purifier further includes a second filter assembly 40 , which is mounted on the housing 10 . The second filter assembly 40 is disposed at the air outlet 12 for secondary filtering of oil smoke.

[0044] Specifically, in one embodiment of the present invention, referring to Figure 2 The second filter assembly 40 includes a second filter housing 41, a second composite filter screen 42, and an air outlet grille 44. The second filter housing 41 is installed in the housing 10, the second composite filter screen 42 is installed in the second filter housing 41, and the air outlet grille 44 is installed at the air outlet 12 at the top of the housing 10. The air outlet grille 44 is used to distribute the air to avoid noise.

[0045] In one embodiment of the present invention, referring to Figure 5-8 The second composite filter screen 42 includes a fourth filter layer 421 and a fifth filter layer 422 .

[0046] In one embodiment of the present invention, the smoke gas drawn into the shell 10 by the air induced component 30 passes through the air inlet grille 22, the first filter layer 231, the second filter layer 232 and the third filter layer 233 in sequence and then enters the guide air duct. Under the guidance of the air duct, the smoke gas enters the second filter component 40. After passing through the fourth filter layer 421 and the fifth filter layer 422 in sequence, the smoke gas is discharged to the outside through the air outlet grille 44.

[0047] Preferably, in one embodiment of the present invention, referring to Figures 5-8, the fifth filter layer 422 is composed of a plurality of filter paper columns 43. The filter paper columns 43 are annular triangular prisms that are connected at the top and bottom. The plurality of filter paper columns 43 are arranged in an array on the first filter layer 231. The upper openings of the filter paper columns 43 are glued to form adhesive seals 50, and the gaps between the lower openings of adjacent filter paper columns 43 are glued to form adhesive seals 50.

[0048] Combine Figure 5-8 It can be seen that when the smoke enters the housing 10, it enters the fourth filter layer 421 and has a tendency to move toward the fifth filter layer 422. Since the gaps between the lower openings of adjacent filter paper columns 43 are sealed, the smoke can only enter the interior of the filter paper column 43 from the lower opening of the filter paper column 43, i.e. Figure 8 As shown, smoke passes through the fourth filter layer 421 and enters the fifth filter layer 422. Due to the adhesive seal on the top of the filter paper column 43, the smoke can only escape from the sides of the filter paper column 43. This increases the contact area and friction probability between the smoke and the filter paper, thereby improving the filter paper's efficiency in removing pollutants from the airflow. The multiple airflow channels also evenly distribute the airflow, creating a laminar flow and preventing turbulence. This results in gentler airflow and further reduces noise.

[0049] Preferably, in one embodiment of the present invention, the filter paper column 43 can be a ring-shaped triangular prism formed by folding one or more composite materials such as non-woven fabric, meltblown fabric, carbon-containing fabric, PET, carbon fiber, MOF material, etc., and is mainly used for deep removal of particulate pollutants in the airflow.

[0050] Preferably, in one embodiment of the present invention, the fourth filter layer 421 includes but is not limited to: activated carbon, manganese sand, foam carbon, carbon fiber, ceramic materials, etc., and its main function is to adsorb and remove volatile organic pollutants and odors contained in the air flow.

[0051] Preferably, in an embodiment of the present invention, a shock-absorbing pad 13 is further provided at the bottom of the housing 10 , and the shock-absorbing pad 13 can be made of a material with shock-absorbing properties such as silicone, rubber, etc.

[0052] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and the utility model concept of the present invention, and all these changes or substitutions should fall within the scope of protection of the present invention.
