Description

Technical Field

[0001] The invention relates to the technical field of air purification equipment, and in particular to a filtering device for an oil fume purifier. Background Art

[0002] In today's home kitchens and commercial kitchen environments, the problem of oil fume purification has always been an important problem that troubles people. As people pay more attention to the quality of life and health, higher requirements are also placed on the performance of oil fume purifier filter devices.

[0003] The filtering effect of traditional fume purifiers is obviously insufficient. The common single-mesh filtering device can only filter larger fume particles and cannot effectively remove tiny oil droplets and odor molecules, resulting in odor in the purified air. In addition, residual fume stains are easily attached to the surfaces of walls, furniture, etc. in the kitchen, which not only affects the appearance but also makes them difficult to clean. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a filter device for an oil fume purifier, which solves the problem that the traditional filter device of an oil fume purifier cannot effectively remove tiny oil droplets and odor molecules, resulting in odor in the purified air.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a filtering device for an oil fume purifier, comprising a fixed frame, wherein filter plate one, filter plate two and filter plate three are slidably connected inside the fixed frame, a limiting plate one is fixedly connected inside the upper side of the fixed frame, and a limiting plate one is fixedly connected inside the lower side of the fixed frame, the inner walls of the limiting plate one and the limiting plate two are arranged on the outer walls of the filter plate one, the filter plate two and the filter plate three, and the outer walls of the filter plate one, the filter plate two and the filter plate three are fixedly connected with handrails.

[0006] Preferably, the outer wall of the fixed frame is fixedly connected with a mounting block, a spring is arranged inside the mounting block, a sliding column is arranged at the bottom end of the spring, and the outer wall of the sliding column is slidably connected to the inside of the mounting block.

[0007] Preferably, a conical block 1 is provided inside the mounting block, a fixing column is fixedly connected inside the conical block 1, a right side outer wall of the fixing column is slidably connected with a conical block 2, a right side outer wall of the fixing column is fixedly connected with a support column 1, a right side outer wall of the support column 1 is fixedly connected with a support column 2, and a right side outer wall of the support column 2 is fixedly connected with a fixing plate.

[0008] Preferably, the interior of the filter plate 1 includes a mounting layer and a connecting layer, the mounting layer is made of nano silver particles, and the connecting layer is made of nano titanium dioxide.

[0009] Preferably, the first limiting plate and the second limiting plate are provided with sliding grooves adapted to the first filter plate, the second filter plate and the third filter plate.

[0010] Preferably, the first limiting plate and the second limiting plate are made of plastic hard sheets.

[0011] Preferably, the areas of the first filter plate, the second filter plate and the third filter plate are 0.2 - 0.5 m 2 .

[0012] Preferably, the fixing plate is provided with a plurality of mounting holes. The diameter of the mounting holes is 6 - 10 mm, and the distance between adjacent mounting holes is 30 - 50 mm.

[0013] Preferably, the taper of the first conical block and the second conical block is 30° - 45°.

[0014] Preferably, the elastic coefficient of the spring is 30 - 50 N / m, and the free length is 80 - 100 mm.

[0015] Working principle: By arranging the first filter plate, the second filter plate and the third filter plate inside the fixed frame, it is possible to filter oil fume particles and impurities of different particle sizes for each layer of filter screen. From the outside to the inside, the pore size of the filter screen gradually becomes smaller, forming a progressive filtration. The outermost layer is a coarse filter screen, the middle layer is a fine filter screen for filtering tiny oil droplets; the innermost layer is an adsorption filter screen for removing odor molecules. This structure greatly improves the filtration efficiency, and each layer of filter screen is relatively independent, facilitating separate cleaning or replacement.

[0016] By installing the fixing plate on the outer wall of the range hood, when the fixed frame needs to be installed, manually push the fixed frame, and the fixed frame will drive the mounting block to slide. When the sliding column slides to the right outer wall of the first conical block, the sliding column will slide on the outer wall of the fixed column. When the fixed frame needs to be removed, manually push the fixed frame, and the fixed frame will drive the sliding column to slide to the right outer wall of the second conical block, then manually pull the fixed frame, and the sliding column will drive the second conical block to slide on the outer wall of the fixed column. When the left outer wall of the second conical block touches the right outer wall of the first conical block, the sliding column will slide to the outer wall of the first conical block, and finally remove the fixed frame. Thus, it can be achieved that the user can quickly complete the assembly and disassembly of the device without the aid of tools, which greatly facilitates daily cleaning and maintenance and component replacement when needed, reducing the user's usage difficulty and maintenance cost.

[0017] By adding an installation layer and a connection layer inside the first filter plate, it can be achieved that due to the unique physical and chemical properties of silver nanoparticles, they can interact with biological macromolecules such as proteins and nucleic acids of bacteria and viruses, destroying their structures and functions; titanium dioxide nanoparticles will generate strongly oxidizing free radicals under ultraviolet irradiation, which can effectively decompose the organic components of bacteria and viruses.

[0018] The present invention provides a filtering device for an oil fume purifier. It has the following beneficial effects:

[0019] 1. By installing Filter Plate 1, Filter Plate 2, and Filter Plate 3 inside the fixed frame, the present invention can filter oil fume particles and impurities of different particle sizes for each layer of filter screen. From the outside to the inside, the aperture of the filter screen gradually becomes smaller, forming a progressive filtration. The outermost layer is a coarse filter screen, the middle layer is a fine filter screen for filtering tiny oil droplets, and the innermost layer is an adsorption filter screen for removing odor molecules. This structure greatly improves the filtration efficiency, and each layer of filter screen is relatively independent, facilitating separate cleaning or replacement.

[0020] 2. By manually pushing the fixed frame, the fixed frame will drive the sliding column to be fixed on the outer wall of the fixed column. Thus, the user can quickly complete the assembly and disassembly of the device without the aid of tools, which greatly facilitates daily cleaning and maintenance and the replacement of components when needed, reducing the user's operation difficulty and maintenance cost.

[0021] 3. By adding silver nanoparticles and titanium dioxide nanoparticles inside Filter Plate 1, the present invention can avoid having negative impacts on human health and the environment, conforming to the concept of green environmental protection and providing a strong guarantee for creating a safe and healthy cooking environment for users.

[0029] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0030] Please refer to the attached Figure 1 - attached Figure 3 , an embodiment of the present invention provides a filtering device for an oil fume purifier, including a fixed frame 1. A first filter plate 2, a second filter plate 3 and a third filter plate 4 are slidably connected inside the fixed frame 1. A first limiting plate 6 is fixedly connected to the upper inner side of the fixed frame 1, and a first limiting plate 6 is fixedly connected to the lower inner side of the fixed frame 1. The inner walls of the first limiting plate 6 and the second limiting plate 7 are arranged on the outer walls of the first filter plate 2, the second filter plate 3 and the third filter plate 4. Handrails 5 are fixedly connected to the outer walls of the first filter plate 2, the second filter plate 3 and the third filter plate 4.

[0031] Specifically, by arranging the first filter plate 2, the second filter plate 3 and the third filter plate 4 inside the fixed frame 1, holes are arranged inside the first filter plate 2, the second filter plate 3 and the third filter plate 4. The holes in the first filter plate 2, the second filter plate 3 and the third filter plate 4 are from large to small, so that each layer of filter screen can filter oil fume particles and impurities of different particle sizes. From the outside to the inside, the aperture of the filter screen gradually becomes smaller, forming a progressive filtration. The outermost layer is a coarse filter screen to intercept larger oil fume particles and food residues; the middle layer is a fine filter screen to filter tiny oil droplets; the innermost layer is an adsorption filter screen to remove odor molecules. This structure greatly improves the filtration efficiency, and each layer of filter screen is relatively independent, facilitating separate cleaning or replacement.

[0032] Please refer to the attached Figure 3 - attached Figure 5 , an installation block 8 is fixedly connected to the outer wall of the fixed frame 1. A spring 9 is arranged inside the installation block 8. A sliding column 10 is arranged at the bottom end of the spring 9. The outer wall of the sliding column 10 is slidably connected inside the installation block 8. A first tapered block 11 is arranged inside the installation block 8. A fixed column 12 is fixedly connected inside the first tapered block 11. A second tapered block 16 is slidably connected to the right outer wall of the fixed column 12. A first support column 13 is fixedly connected to the right outer wall of the fixed column 12. A second support column 14 is fixedly connected to the right outer wall of the first support column 13.

[0033] Specifically, by installing the fixing plate 15 on the outer wall of the range hood, when it is necessary to install the fixing frame 1, manually push the fixing frame 1. The fixing frame 1 will drive the installation block 8 to slide. The sliding of the installation block 8 will drive the sliding column 10 to squeeze the first conical block 11. When the sliding column 10 slides to the right outer wall of the first conical block 11, the sliding column 10 will slide on the outer wall of the fixed column 12 and finally lock the fixing frame 1. When it is necessary to remove the fixing frame 1, manually push the fixing frame 1. The fixing frame 1 will drive the sliding column 10 to slide to the right outer wall of the second conical block 16, and then manually pull the fixing frame 1. The sliding column 10 will drive the second conical block 16 to slide on the outer wall of the fixed column 12. When the left outer wall of the second conical block 16 touches the right outer wall of the first conical block 11, the sliding column 10 will slide to the outer wall of the first conical block 11, and finally remove the fixing frame 1. Thus, the user can quickly complete the assembly and disassembly of the device without the need for tools, which greatly facilitates daily cleaning and maintenance and component replacement when needed, reducing the user's usage difficulty and maintenance cost.
