Description

Technical Field

[0001] This utility model relates to the field of purification and filtration technology, specifically to a purification and filtration structure. Background Technology

[0002] Range hoods are electrical appliances used in kitchens to absorb and remove cooking fumes and odors. They use a motor-driven fan to create negative pressure, which draws in the fumes and separates them from the grease through filters and oil screens before expelling the purified air outdoors. However, traditional range hoods often have an integrated design for their filter unit and exhaust system, making it inconvenient to clean or replace the internal filters and filter elements. If one part is damaged, the entire unit needs to be replaced, which is not convenient for maintenance. Utility Model Content

[0003] The purpose of this utility model is to provide a purification and filtration structure to solve the problems mentioned in the background art, where the filter unit and exhaust system of traditional range hoods are mostly integrated, making it inconvenient to clean or replace the internal filter screen and filter element, and requiring the entire unit to be replaced when a certain component is damaged, which is inconvenient for maintenance.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a purification and filtration structure, comprising:

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1 to 7 This utility model provides a technical solution: a purification and filtration structure, including: a range hood 1; an exhaust frame 2 fixedly connected to the top of the range hood 1, and a connecting frame 3 fixedly connected to the top of the exhaust frame 2; a fixing frame 18 installed on the inner side of the connecting frame 3 by bolts, and an electrostatic separation device 19 installed on the inner side of the fixing frame 18; an installation frame 4 installed above the connecting frame 3; a particulate matter interception filter box 14 placed on the inner side of the installation frame 4, and an odor adsorption device 13 provided on the top of the particulate matter interception filter box 14; an exhaust hood 5 fixedly connected to the top of the installation frame 4, and a fixing baffle 12 fixedly connected inside the exhaust hood 5; an inner sliding plate 8 slidably disposed on the top of the fixing baffle 12, and the inner sliding plate 8 slidably connected to the exhaust hood 5, and multiple ventilation openings 9 are equidistantly provided inside the inner sliding plate 8 and the fixing baffle 12.

[0028] It should be noted that in this embodiment, the range hood 1 includes a smoke collection chamber, an oil filter, a motor, a centrifugal impeller, a volute, an oil box, and a control panel. The motor provides power, and the centrifugal impeller rotates at high speed to generate centrifugal force, throwing out the fumes. The volute guides the airflow, reducing noise and improving smoke extraction efficiency. The fumes enter the connecting frame 3 through the exhaust frame 2. The fixed frame 18 and electrostatic separation device 19 installed inside the connecting frame 3 adsorb the charged fumes particles. The particulate matter interception filter box 14 further filters the fumes. After filtration, the odor adsorption device 13 adsorbs aldehydes and benzene compounds in the fumes. The output end of the electric telescopic rod 10 drives the inner sliding plate 8 and the vent 9 to move, aligning the vent 9 in the inner sliding plate 8 with the vent 9 in the fixed baffle 12. For exhaust treatment, when the range hood is not in use, the output end of the electric telescopic rod 10 drives the inner sliding plate 8 and the vent 9 to move, thus misaligning the vent 9 in the inner sliding plate 8 with the vent 9 in the fixed baffle 12. This prevents external air and fumes from entering the mounting frame 4 through the exhaust pipe 6 and exhaust hood 5. When maintenance is required, remove the bolts connecting the fixed frame 18 and the connecting frame 3, and the fixed frame 18 and the electrostatic separation device 19 can be pulled out for cleaning and maintenance. By rotating and removing the mounting nut 17 on the outside of the fixing screw 15, the connecting frame 3 and the mounting frame 4 can be separated. The positioning side plate 20 and the positioning groove 21 on the outside of the particulate matter interception filter box 14 provide limiting support. After removing the mounting frame 4, the particulate matter interception filter box 14 and the odor adsorption device 13 can be removed for maintenance.

[0029] In one embodiment, such as Figures 1 to 5 As shown, positioning side plates 20 are fixed to both sides of the particulate matter interception filter box 14. The top of the connecting frame 3 is symmetrically provided with positioning grooves 21 that cooperate with the positioning side plates 20. The bottom of the mounting frame 4 is symmetrically provided with bottom limiting grooves 22 that cooperate with the positioning side plates 20.

[0030] It should be noted that in this embodiment, the positioning side plate 20 on the outside of the particulate matter interception filter box 14 and the positioning groove 21 provide limiting support, which limits the placement of the particulate matter interception filter box 14 and the odor adsorption device 13 at the top of the connecting frame 3. The bottom limiting groove 22 at the bottom of the mounting frame 4 cooperates with the positioning side plate 20 to restrict the position of the positioning side plate 20 in the positioning groove 21, thereby fixing the installation position of the odor adsorption device 13 and the particulate matter interception filter box 14.

[0031] In one embodiment, such as Figures 1 to 7 As shown, multiple fixing screws 15 are fixed to the top of the connecting frame 3, and mounting plate 16 that mate with the fixing screws 15 are symmetrically fixed to both sides of the mounting frame 4. Mounting nuts 17 that mate with the fixing screws 15 are provided above the mounting plate 16.

[0032] It should be noted that in this embodiment, the fixing screw 15 cooperates with the mounting hole plate 16, and the mounting nut 17 is threaded on the outside of the fixing screw 15. At this time, the mounting frame 4 can be stably installed on the top of the connecting frame 3.

[0033] In one embodiment, such as Figures 1 to 7 As shown, a side fixing box 7 is fixedly connected to one side of the exhaust hood 5. An electric telescopic rod 10 is installed inside the side fixing box 7. The output end of the electric telescopic rod 10 is fixedly connected to the inner sliding plate 8.

[0034] It should be noted that in this embodiment, the output end of the electric telescopic rod 10 drives the inner sliding plate 8 to slide and adjust, and the inner sliding plate 8 slides and adjusts on the top of the fixed baffle 12.

[0035] In one embodiment, such as Figures 1 to 7 As shown, a limiting slide rod 11 is symmetrically fixed to one side of the inner sliding plate 8. The limiting slide rod 11 is slidably connected to the exhaust hood 5 and slidably connected to the side fixed box 7.

[0036] It should be noted that in this embodiment, when the inner sliding plate 8 slides, it drives the limiting slide rod 11 on one side to move. The limiting slide rod 11 limits the sliding with the exhaust hood 5 and the side fixing box 7, thereby improving the adjustment stability of the inner sliding plate 8.

[0037] In one embodiment, such as Figures 1 to 5 As shown, an exhaust pipe 6 is fixed to the top of the exhaust hood 5, a HEPA filter material is installed inside the particulate matter interception filter box 14, and activated carbon fiber material is installed inside the odor adsorption device 13.

[0038] It should be noted that in this embodiment, the HEPA filter material in the particulate matter interception filter box 14 filters the oil fumes, and the activated carbon fiber material in the odor adsorption device 13 adsorbs aldehydes and benzene compounds in the oil fumes.
