Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

Examples

Referring to fig. 1-3, the oil smoke exhaust device with the sterilization filter screen of the embodiment includes a cavity 1, the cavity 1 is provided with an air inlet and an air outlet, a fan system 2 for exhausting oil smoke is installed in the cavity 1, an air suction end of the fan system 2 is connected with the air inlet of the cavity 1, and an air exhaust end of the fan system 2 is connected with the air outlet of the cavity 1; the air inlet of the cavity 1 is also provided with a mesh enclosure 11 for allowing kitchen oil smoke to enter the cavity 1 from meshes 111 of the mesh enclosure 11, and the surface of the mesh enclosure 11 is covered with a smell purification functional layer 12 for releasing particles for inhibiting bacteria and decomposing grease.

When the oil smoke exhausting equipment works, under the pumping and exhausting action of the fan system 2, oil smoke generated in a kitchen sequentially enters the cavity 1 from the air inlet of the fan and the meshes 111 of the mesh enclosure 11, the oil smoke entering the cavity 1 enters the fan system 2 from the air suction end of the fan system 2, and is exhausted outdoors from the air exhaust end of the fan system 2 and the air outlet of the cavity 1 sequentially, so that the oil smoke in the kitchen is pumped and exhausted.

In practical application, the oil smoke can pollute air contacted with the oil smoke, so that the polluted air is rich in grease and is easy to generate peculiar smell; and when the air is polluted, the hot oil fume can exchange heat with the polluted air, so that the temperature of the air polluted by the oil fume is usually higher than the atmospheric temperature, and the air polluted by the oil fume is easy to breed bacteria and germs after being condensed to generate peculiar smell.

Based on this, in order to achieve the effect of odor purification, the oil fume exhaust equipment covers the net cover 11 at the air inlet, and thus, in the process that oil fume enters the cavity 1 from the air inlet, the polluted hot air rich in grease can be rapidly cooled and condensed when passing through the surface of the cooler odor purification functional layer 12, so that grease in the polluted hot air can be adsorbed on the odor purification functional layer 12 covered on the surface of the net cover 11, therefore, the odor purification functional layer 12 can continuously release particles within 24 hours, so as to decompose grease on the surface of the odor purification functional layer, and play an effective role in blocking bacteria and germs from escaping to a kitchen space, further optimize the air quality of the kitchen, prevent bacteria and germs in the cavity 1 of the oil fume exhaust equipment from polluting the air of the kitchen, effectively avoid the generation of foul odor in the kitchen and the oil fume exhaust equipment, and achieve a better odor purification effect.

In addition, the oil smoke exhaust equipment only needs to cover the odor purification functional layer 12 on the surface of the mesh enclosure 11, does not need to install other sterilization and odor removal functional components, has simple structure and can reduce the production cost; and the odor purification effect can be realized through the odor purification functional layer 12, the electric energy consumption is not needed, and the use cost can be reduced.

In order to facilitate the cleaning, maintenance and replacement of the mesh enclosure covered with the odor purification functional layer 12, the mesh enclosure 11 is detachably mounted at the air inlet of the cavity 1; preferably, the mesh cover 11 is inserted at the air inlet of the cavity 1.

The coverage area of the odor-suppressing functional layer 12 is preferably not smaller than the surface area of the mesh cover 11; therefore, the oil smoke entering the cavity 1 will inevitably pass through the odor purification functional layer 12 on the surface of the mesh enclosure 11, so that the coverage area of the odor purification functional layer 12 on the surface of the mesh enclosure 11 is increased, the odor purification functional layer 12 can be in large-area contact with the oil smoke sucked into the cavity 1, and the sterilization and odor removal effects of the oil smoke are further improved.

Wherein, the odor purification functional layer 12 is a plating layer structure formed on the surface of the mesh enclosure 11 by electroplating; the plating layer structure formed by adopting the electroplating technology has the advantages of uniformity, lightness, thinness and compactness, can reduce the material consumption of the odor-purifying functional layer 12 and reduce the production cost, has better adhesion performance with the surface of the mesh enclosure 11, and can ensure that the odor-purifying functional layer 12 is not easy to fall off after being used for a long time, thereby ensuring the long-acting odor-purifying and bacteria-inhibiting effect.

"a research on antibacterial activity and antibacterial mechanism of a nano platinum antibacterial agent" of China journal of Disinfection science adopts Minimum Inhibitory Concentration (MIC) determination, antibacterial ring test method and scanning electron microscope technology to carry out laboratory research on the in vitro antibacterial activity and the action mechanism of the nano platinum antibacterial agent; the results show that: the antibacterial rings of the nano platinum antibacterial solution stock solution to 7 bacterial propagules are respectively 13mm and above, and the antibacterial rings to aspergillus oryzae are respectively 16mm and above; the MIC value of the nano platinum antibacterial agent to the indicator bacteria of escherichia coli, pseudomonas aeruginosa and staphylococcus aureus reaches 2048 times of dilution; the observation of a scanning electron microscope shows that the thallus structure of the bacterial propagules is damaged to different degrees after the action of the nano platinum antibacterial agent. Therefore, the conclusion is that: the nano platinum antibacterial agent has strong in-vitro antibacterial effect and has a destructive effect on bacterial thalli. In addition, researches show that the nano platinum ions also have strong decomposition capacity on grease molecules.

Based on this, in the range hood apparatus of this embodiment, the odor purification functional layer 12 is preferably a nano platinum plating layer, nano platinum ions released by the nano platinum plating layer have a strong decomposition capability, and can decompose odor molecules in the adsorbed grease, and release a large amount of nano platinum particles to inhibit bacteria, and the odor purification functional layer 12 can continuously release nano platinum ions for 24 hours to decompose odor molecules and inhibit bacteria from escaping to the kitchen space, thereby playing an effective intercepting role; and further, the excellent odor-purifying and bacterium-inhibiting effects can be realized, so that the air quality of the kitchen is optimized.

In addition, the odor-removing functional layer 12 can also be a silver coating, and silver ions released by the silver coating can also play a certain odor-removing and bacteriostatic effect. The silver plating is preferably a nano-silver plating. Compared with the common silver plating layer, the nano silver plating layer has small metal silver particles, large relative surface area and increased amount of nano silver ions capable of being released due to large area, so that the nano silver plating layer has better odor-removing and bacteriostatic effects compared with the common silver plating layer.
