[0033] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0034] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0035] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0036] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0037] like Figures 1-3 As shown, the kitchen fume purification device provided by the present invention includes a fume collection hood 1, a cyclone purification device 2, and a cleaning device 3. The fume collection hood 1 has an internal fume collection space 11, an air inlet 12 at its bottom, and an exhaust vent 13 on its top wall. In practice, cooking fumes enter through the air inlet 12 and are concentrated inside the fume collection space 11, then are discharged through the exhaust vent 13. A fan can typically be installed to extract the fumes; such extraction equipment is a mature existing technology in the field and will not be described in detail here.

[0038] The exhaust vent 13 can be set to one or more, and no specific limit is made here.

[0039] The cyclone purifier 2 is fixedly connected to the gas collection hood 1 and located within the gas collection space 11. The exhaust vent 13 is connected to the cyclone purifier 2. Kitchen fumes are configured to be drawn into the gas collection space 11 through the air inlet 12 and then discharged sequentially through the cyclone purifier 2 and the exhaust vent 13. In other words, before being discharged through the exhaust vent 13, the kitchen fumes will flow through the cyclone purifier 2 for filtration and purification.

[0040] The cyclone purification device 2 utilizes the principle of eddies to guide the fluid into a rotating state, causing the particles within to settle due to centrifugal force, thereby achieving a purification effect. After passing through the cyclone purification device 2, kitchen fumes can achieve effective separation of water and oil. Due to the lower density of oil, it will be concentrated in the center of the cyclone due to centrifugal force, while water will flow out from the periphery of the cyclone.

[0041] The cleaning device 3 includes a connected inlet pipe 31 and an outlet pipe 32. The inlet pipe 31 is located on the outer wall of the gas collection hood 1, and the outlet pipe 32 is installed inside the gas collection space 11. The outlet pipe 32 is configured to deliver cleaning water to the cyclone purification device 2. Specifically, the inlet pipe 31 can be connected to hot or cold water, or an appropriate amount of cleaning liquid can be added to the water to more effectively clean the cyclone purification device 2.

[0042] The kitchen fume purification device provided by this invention, by setting up a vortex purification device 2, enables the fumes to rotate, thereby utilizing the vortex principle to more effectively block grease and harmful particles in the fumes, greatly improving filtration efficiency and facilitating high-efficiency purification of fumes. In addition, the kitchen fume purification device also integrates a cleaning device 3 to achieve self-cleaning of the kitchen fume purification device. In this way, users no longer need to manually disassemble and clean the vortex purification device 2 during use, simplifying the cleaning operation and reducing the cleaning difficulty of the kitchen fume purification device.

[0043] like Figure 3 and Figure 4 As shown, in some embodiments, the cyclone purification device 2 includes a first cyclone purification grille 21 and a second cyclone purification grille 22. Both the first cyclone purification grille 21 and the second cyclone purification grille 22 are connected to the gas collection hood 1 via a fixed bracket 4. The second cyclone purification grille 22 is disposed between the first cyclone purification grille 21 and the exhaust port 13. That is, the cyclone purification device 2 has two-stage purification barriers. The oil fumes first enter the first cyclone purification grille 21 for primary filtration and purification, and then the oil fumes after primary purification enter the second cyclone purification grille 22 for secondary filtration and purification. The two-stage filtration and purification can filter and block more pollutants in the oil fumes, effectively improving the oil pollution purification effect of the cyclone purification device 2.

[0044] Specifically, such as Figure 4 As shown, the bars 211 of the first cyclone purification grille 21 are designed with an arc-shaped cross-section to create vortices when oil fumes pass through. This structure is simple and has low production costs. The structure of the second cyclone purification grille 22 can be referred to... Figure 4 The first vortex purification grille 21 is set in the middle.

[0045] In other embodiments, the cyclone purification device 2 can also be configured as a combination of a cyclone separator and a mesh grille. The oil fumes first pass through the cyclone separator to rotate the airflow, causing the grease particles in the fumes to rotate and gather, and then be deposited by gravity. The mesh grille further filters solid particles in the air, ensuring that the oil fumes are purified to form cleaner gas for emission. The specific configuration can be determined according to the actual situation.

[0046] like Figure 3 and Figure 5As shown, in some embodiments, the water outlet pipe 32 is disposed between the first vortex purification grid 21 and the second vortex purification grid 22. A plurality of first nozzles 33 are disposed on the side of the water outlet pipe 32 near the first vortex purification grid 21. The first nozzles 33 are connected to the water inlet pipe 31 through the water outlet pipe 32.

[0047] With this setup, multiple first nozzles 33 can rinse the first vortex purification grille 21 when they spray water, and can more comprehensively cover all parts of the first vortex purification grille 21, which helps to improve cleaning efficiency.

[0048] Furthermore, multiple second nozzles 34 are provided on the side of the water outlet pipe 32 near the second vortex purification grille 22, and the second nozzles 34 are connected to the water inlet pipe 31 through the water outlet pipe 32. In this way, the multiple first nozzles 33 and the multiple second nozzles 34 can simultaneously rinse the first vortex purification grille 21 and the second vortex purification grille 22, further improving the cleaning efficiency.

[0049] Optionally, the first nozzle 33 and the second nozzle 34 are evenly spaced along the length of the water outlet pipe 32. This ensures that the first vortex purification grille 21 and the second vortex purification grille 22 receive cleaning water evenly, effectively improving the cleaning effect.

[0050] like Figure 3 As shown, in some embodiments, the bottom of the cyclone purification device 2 is provided with a water collector 5 and an oil collector 6, both of which are connected to the fume collection hood 1. With this configuration, the water and oil separated by the cyclone purification device 2 can flow into the water collector 5 and oil collector 6 respectively, preventing water and oil from dripping onto the kitchen countertop and improving the practicality of the kitchen fume purification device.

[0051] Optionally, the water collecting component 5 can be configured as a water collecting trough, and the oil collecting component 6 can be configured as an oil collecting box.

[0052] Furthermore, the water collecting component 5 is provided with a drain outlet 51 that runs through the inside and outside, and the oil collecting component 6 is detachably connected to the gas collecting hood 1.

[0053] By setting up a drain outlet 51, users can easily drain the water inside the water collection component 5 in a timely manner, avoiding excessive water accumulation and overflow; the detachable design of the oil collection component 6 makes it convenient for users to remove it for cleaning, which helps to improve the practicality of the kitchen fume purification device and enhance the user experience.

[0054] In this embodiment, the water collecting component 5 and the oil collecting component 6 are installed on the rear wall of the gas collecting hood 1. Along the direction towards the rear wall of the gas collecting hood 1, the first vortex purification grid 21 and the second vortex purification grid 22 gradually tilt downward, so that the water and oil on the first vortex purification grid 21 and the second vortex purification grid 22 flow backward and downward under the action of gravity, making it easier to be collected by the water collecting component 5 and the oil collecting component 6.

[0055] like Figure 3 As shown, in some embodiments, the kitchen fume purification device further includes an air curtain fan 8, which is fixedly installed on the fume collection hood 1. The air curtain fan 8 can exhaust gas outward and form an air curtain, which can block the oil fumes at the air inlet 12 from spreading outward. That is, the formation of the air curtain prevents the oil fumes from spreading to other parts of the kitchen. In this way, it can ensure that the oil fumes are concentrated inside the fume collection space 11 and discharged from the exhaust vent 13 to a greater extent, which is beneficial to ensuring the air quality in the kitchen and improving the kitchen working environment.

[0056] Specifically, the air intake of the air curtain fan 8 can be set above the kitchen ceiling to directly draw in air from above the kitchen ceiling without the need to connect to outdoor fresh air; in addition, the air curtain fan 8 can be embedded in the air collection hood 1 to save space and reduce the difficulty of installation.

[0057] like Figure 2 As shown, in some embodiments, the number of air curtain fans 8 is set to two, and the two air curtain fans 8 are spaced apart along the width direction of the air collection hood 1.

[0058] With this setup, the two air curtain fans work together to generate a stronger airflow curtain, enhancing the effect of preventing the spread of oil fumes.

[0059] like Figure 3 As shown, in some embodiments, the kitchen fume purification device further includes a UV lamp 7, which is fixedly connected to the fume collection hood 1 and positioned between the outlet of the cyclone purification device 2 and the inlet of the exhaust vent 13. The UV lamp 7 refers to an ultraviolet lamp (UV). This arrangement enables the exhaust air from the fume collection hood 1 to be sterilized, disinfected, and odor-removed, further improving the cleanliness of the gas emitted from the fume collection hood 1 into the external environment and reducing pollution to the external environment.

[0060] like Figure 3 As shown, in some embodiments, the kitchen fume purification device also includes a lighting lamp 9, which is fixedly connected to the top wall of the fume collection space 11. Optionally, the lighting lamp 9 can be embedded in the fume collection hood 1. The lighting lamp 9 can supplement the illumination requirements of the cooking area, which is beneficial to improving the user experience.

[0061] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
