Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air purification equipment, in particular to a filtering device for an oil fume purification machine. BACKGROUND

[0002] In today's home kitchen and commercial kitchen environment, the problem of oil fume purification has always been an important problem that plagues people. With the continuous improvement of people's attention to life quality and health, higher requirements have been put forward for the performance of the oil fume purification machine filtering device.

[0003] The traditional oil fume purification machine filtering device has obvious deficiencies in the filtering effect. The common single filter screen filtering device can only simply filter relatively large particle size oil fume particles, and cannot effectively remove tiny oil droplets and odor molecules, resulting in that the purified air still has odor, and the surfaces of walls, furniture and the like in the kitchen are easy to attach residual oil fume stains, which not only affects the appearance, but also is difficult to clean. SUMMARY

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

[0005] To achieve the above purpose, the present application is realized by the following technical scheme: a filtering device for an oil fume purification machine, comprising a fixed frame, a filter plate one, a filter plate two and a 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, 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, the inside of the mounting block is provided with a spring, the bottom end of the spring is provided with a sliding column, and the outer wall of the sliding column is slidably connected in the inside of the mounting block.

[0007] Preferably, the inside of the mounting block is provided with a conical block one, the inside of the conical block one is fixedly connected with a fixed column, the right outer wall of the fixed column is slidably connected with a conical block two, the right outer wall of the fixed column is fixedly connected with a support column one, the right outer wall of the support column one is fixedly connected with a support column two, and the right outer wall of the support column two is fixedly connected with a fixed plate.

[0008] Preferably, the inside of the filter plate one comprises an installation layer and a connection layer, the installation layer adopts nano silver particles, and the connection layer adopts nano titanium dioxide.

[0009] Preferably, the limiting plate one and the limiting plate two are provided with a sliding groove matched with the filter plate one, the filter plate two and the filter plate three.

[0010] Preferably, the limiting plate one and the limiting plate two are made of a plastic hard sheet.

[0011] Preferably, the filter plate one, the filter plate two and the filter plate three have an area of 0.2-0.5m 2 .

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

[0013] Preferably, the taper block one and the taper block two have a taper of 30°-45°.

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

[0015] Working principle: By setting the filter plate one, the filter plate two and the filter plate three inside the fixed frame, each layer of filter screen can filter oil smoke particles and impurities of different particle sizes from outside to inside, the filter screen aperture gradually decreases, forming progressive filtration, the outermost layer is a coarse filter screen, the middle layer is a fine filter screen, and the innermost layer is an adsorption filter screen, which removes odor molecules. This structure greatly improves the filtering efficiency, and each layer of filter screen is relatively independent, facilitating individual 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, the fixed frame is manually pushed, the fixed frame drives the mounting block to slide, when the sliding column slides to the right outer wall of the taper block one, the sliding column slides on the outer wall of the fixed column, when the fixed frame needs to be taken out, the fixed frame is manually pushed, the fixed frame drives the sliding column to slide to the right outer wall of the taper block two, then the fixed frame is manually pulled, the sliding column drives the taper block two to slide on the outer wall of the fixed column, when the left outer wall of the taper block two touches the right outer wall of the taper block one, the sliding column slides to the outer wall of the taper block one, and finally the fixed frame is taken out, so that the user can quickly complete the assembly and disassembly of the device without the aid of tools, greatly facilitating daily cleaning and maintenance and replacement of parts when needed, reducing the user's use difficulty and maintenance cost.

[0017] By increasing the installation layer and the connection layer inside the filter plate one, the nano silver particles can interact with biological macromolecules such as proteins and nucleic acids of bacteria and viruses due to their unique physical and chemical properties, thereby destroying their structure and function; nano titanium dioxide can generate strong oxidizing free radicals under ultraviolet irradiation, which can effectively decompose the organic components of bacteria and viruses.
