DETAILED DESCRIPTION

[0031] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0032] The present application relates to an oil fume purifier, comprising a housing 100 , a filtering molecular sieve 200 , a high-voltage electric ionization ozone generating mechanism 300 and an electronic control component 400 .

[0033] As shown in Figures 1, 2 and 3, the interior of the shell 100 is hollow to form a accommodating space 101, and an air inlet 102 and several air outlets 103 are provided on the shell 100. The air inlet 102 and each air outlet 103 are connected to the accommodating space 101. In the direction shown in the figure, the air inlet 102 is opened at the bottom of the shell 100, and the air inlet 102 is vertically oriented. The air outlet 103 is opened on the circumferential side wall of the shell 100, and the air outlet 103 is horizontally oriented. The directions of the air inlet 102 and the air outlet 103 are not in the same straight line direction. Preferably, the directions of the air inlet 102 and the air outlet 103 are perpendicular to each other. A filtering molecular sieve 200 is installed at each air outlet 103. The filtering molecular sieve 200 is preferably a molecular sieve made of zeolite molecular sieve or activated carbon material, and can also be made of a material such as cordierite that can adsorb ozone and other odorous gases. The filtering molecular sieve 200 is square, with multiple uniformly sized through-holes distributed in a honeycomb pattern in the center. The ionized ozone generator 300 is installed in the housing 101. The electronic control assembly 400 is mounted on the housing 100 and electrically connected to the ionized ozone generator 300. The electronic control assembly 400 controls the start and stop of the ionized ozone generator 300.

[0034] During operation, gas laden with cooking fumes enters the storage space 101 through the air inlet 102 under the influence of external wind pressure. At this point, the ionized ozone generator 300 activates, ionizing the air to form ozone. Ozone is a strong oxidant that can destroy bacterial cell walls, allowing it to diffuse into the cells and oxidize glucose oxidase, an enzyme essential for the bacteria to oxidize glucose. It can also directly interact with bacteria and viruses, disrupting their metabolism and reproduction. Furthermore, ozone can oxidize various odorous inorganic and organic substances. For example, ozone can decompose odorous gases such as ammonia, benzene, and hydrogen sulfide, thereby acting as a deodorizer. Ozone sterilization, disinfection, and deodorization are quick and effective. The ozone generated by the ionized air generated by the ionized ozone generator 300 effectively removes odors from cooking fumes. The cooking fumes undergo a primary purification process within the storage space 101, then redirect from a vertical flow direction toward the air outlet 103. The oil smoke changes direction in the accommodating space 101, increasing the residence time of the oil smoke in the accommodating space 101, and is purified more fully under the action of the ionized ozone generating mechanism 300. The oil smoke flows through the through-holes of the filter molecular sieve 200 before being discharged from the air outlet 103, and various fluid molecules are screened according to the effective pore size of the filter molecular sieve 200. When a fluid containing ozone and odor flows through, some ozone molecules in the fluid make irregular movements and collide with the adsorbent surface of the through-holes of the filter molecular sieve 200, resulting in molecular concentration on the surface, which reduces the number of ozone molecules in the fluid, achieving the purpose of separating and removing ozone and odor, effectively adsorbing the molecular structure of organic matter and eventually decomposing it, and the gas after the ozone is decomposed is discharged to the outside of the shell 100, making the fluid after the oil smoke purification cleaner and the gas after the ozone is decomposed not harmful to the human body. The filter molecular sieve 200 has good odor adsorption performance, no secondary pollution, and can be used for a long time at room temperature and high temperature. The molecular sieve 200, with its uniform pore size, is an ionic adsorbent that selectively adsorbs molecules based on their size and polarity. Its strong adsorption capacity allows it to maintain even low gas concentrations. After the fume gas passes through the ionized ozone generator 300 for sterilization, disinfection, and deodorization, the resulting ozone is once again adsorbed by the molecular sieve 200 assembly before being discharged to the outside, leaving the exhaust gas even cleaner.

[0035] In some embodiments of the present application, as shown in Figures 1, 2, 3, and 4, the housing 100 has a cubic, box-like structure. Air outlets 103 are provided on the four sidewalls of the housing 100. Flue gas enters the accommodating space 101 from the air inlet 102 at the bottom, then flows through the surrounding molecular sieves 200 for purification. The air outlets 103 and the molecular sieves 200 are arranged around the housing 100, effectively increasing the overall exhaust volume and the total adsorption area of ​​the installed molecular sieves 200. Furthermore, as shown in Figures 2, 3, and 5, the electronic control assembly 400 includes a fixing base 410, an electronic control board 420, a plug socket 430, and an indicator light 440. The electronic control board 420, the plug socket 430, and the indicator light 440 are mounted on the fixing base 410. The fixing base 410 can be fixed to the housing 100 by screws. The fixing base 410 is located opposite the air inlet 102. As shown in the figure, the air inlet 102 is located at the bottom of the housing 100, and the fixing base 410 is mounted on the top of the housing 100. The ionized ozone generator 300 is located in the accommodating space 101 and fixed to the outer wall of the fixing base 410. The air outlets 103 surround the ionized ozone generator 300. Airflow enters the accommodating space 101 from the air inlet 102, then strikes the outer wall of the fixing base 410 and disperses in all directions. The air inlet base 500 is provided with a boss portion 411 that extends into the accommodating space 101 and protrudes toward the air inlet 102. The ionized ozone generator 300 can be mounted on the bottom outer wall of the boss portion 411 by snapping. The air outlets 103 surround the boss portion 411, which is located in the virtual horizontal extension direction of each air outlet 103. The airflow strikes the outer wall of the boss portion 411 and disperses in all directions.

[0036] In some specific embodiments of the present application, as shown in Figures 1, 2, and 3, an air inlet base 500 is mounted on the outside of the housing 100. An air inlet 510 of the air inlet base 500 surrounds the air inlet 102. The air inlet 510 is tapered from the outside toward the air inlet 102. The housing 100 can be connected to an external range fume device via the air inlet base 500. The range fumes are transported to the air inlet 102 through the air inlet 510 of the air inlet base 500.

[0037] In some specific embodiments of the present application, as shown in Figure 4, a card slot 104 is provided on both sides of each air outlet 103 in the shell 100, and the card slot 104 extends in the vertical direction. A group of opposite sides of the filtering molecular sieve 200 slides down into the card slot 104. The other group of opposite sides (upper and lower sides) of the filtering molecular sieve 200 are clamped and fixed in the shell 100. Specifically, a first support wall 412 extends downward from all sides of the fixing seat 410 of the electronic control component 400. A second support wall 105 extends upward from the bottom of the inner wall of the shell 100. The first support wall 412 and the second support wall 105, the second support wall 105 supports the bottom of the filtering molecular sieve 200 upward, and the first support wall 412 presses the top of the filtering molecular sieve 200 downward, and the first support wall 412 and the second support wall 105 are used to clamp and fix the upper and lower sides of the filtering molecular sieve 200.

[0038] In some embodiments of the present application, the electronic control assembly 400 further includes a wind speed sensor 450. The wind speed sensor 450 is used to sense the air volume in the accommodation space 101. Based on the air volume, a signal is fed back to the electronic control assembly 400, which in turn controls the operating voltage of the ionized ozone generating mechanism 300 to change the ionized ozone content.

[0039] This application also relates to a range hood that utilizes the aforementioned oil fume purifier. The oil fume purifier's air inlet 102 is connected to the range hood's intake or exhaust port. The oil fume purifier purifies the range hood's oil fumes before or during exhaust, ensuring they are clean and clear when discharged indoors or outdoors.
