Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0028] The present utility model provides an odor filtering device for a kitchen waste treatment device as shown in Figures 1 to 6 and includes:

[0029] An air extraction device;

[0030] The air extraction device includes an installation cover 1. An installation plate 2 is fixed in the inner cavity of the installation cover 1. An air extraction fan group 3 is embedded on the installation plate 2. A gas transmission pipe 4 is communicated with the top of the installation cover 1;

[0031] A purification device;

[0032] The purification device includes a device box 5. A liquid storage box 6 is fixed on one side of the inner cavity of the device box 5. One end of the gas transmission pipe 4 away from the installation cover 1 penetrates into the inner cavity of the liquid storage box 6. A microbial solution for decomposing organic substances is stored in the liquid storage box 6. A deceleration component 7 for slowly transporting the gas and a stirring component 8 for mixing the gas and the solution are arranged in the liquid storage box 6. A communication pipe 9 is communicated with the top of the liquid storage box 6. One end of the communication pipe 9 away from the liquid storage box 6 extends upward and penetrates into the inner cavity of the device box 5 from the other side and is communicated with an adsorption box 10. An adsorbent is filled in the inner cavity of the adsorption box 10. The adsorbent can be activated carbon. An air outlet pipe 11 extending outward is communicated with the top of the adsorption box 10;

[0033] The odor emitted by the kitchen waste is extracted by the air extraction device and then introduced into the purification device through the gas transmission pipe 4. The microbial solution in the purification device contacts and decomposes the organic substances in the gas, so that the odorous organic substances are decomposed into odorless inorganic substances. At the same time, the adsorbent can adsorb some harmful substances in the gas to ensure that the discharged gas is odorless and harmless, and keep the air fresh during the temporary storage stage of the kitchen waste.

[0034] The deceleration assembly 7 includes a cylindrical barrel 71 fixed inside the liquid storage tank 6. One end of the gas transmission pipe 4 communicates with the top of the cylindrical barrel 71. A transmission motor 72 is fixed outside the liquid storage tank 6. The output shaft of the transmission motor 72 penetrates into the inner cavity of the cylindrical barrel 71 and is fixed with a movable shaft 73. The movable shaft 73 is rotationally connected to the inner cavity of the cylindrical box through a bearing. A spiral blade 74 is fixed on the outer side of the movable shaft 73. The outer side of the spiral blade 74 fits against the inner wall of the cylindrical barrel 71. A through slot 75 is opened on one side of the bottom of the cylindrical barrel 71 close to the gas transmission pipe 4, and an air outlet 76 is opened on one side of the top of the cylindrical barrel 71 away from the gas transmission pipe 4. By driving the movable shaft 73 to rotate through the transmission motor 72, and then the movable shaft 73 drives the spiral blade 74 to rotate, the gas introduced into the cylindrical barrel 71 through the gas transmission pipe 4 is intermittently transported to the other side under the transportation of the spiral blade 74. During the transportation process, the contact between the gas and the liquid is maintained.

[0035] The stirring assembly 8 includes a stirring motor 81 fixed on the top of the equipment box 5. The output shaft of the stirring motor 81 penetrates into the inner cavity of the liquid storage tank 6 and is fixed with a stirring shaft 82. Stirring blades 83 are successively fixed on the outer side of the stirring shaft 82 from top to bottom. By driving the stirring shaft 82 and the stirring blades 83 to rotate through the stirring motor 81, the gas rising in the microbial solution is dispersed, increasing the contact area between the gas and the solution, ensuring that the microorganisms fully decompose the organic matter in the gas, and weakening the odor in the gas.

[0036] A fixing plate 12 is fixed inside the liquid storage tank 6. Dispersing holes 13 are integrally arranged at the center of the fixing plate 12. The fixing plate 12 is located between the cylindrical barrel 71 and the stirring shaft 82. By opening the dispersing holes 13 on the fixing plate 12, it is convenient to block the gas diffusing upward from the air outlet 76 and disperse the gas again, so that the gas is evenly diffused in the solution.

[0037] A protective cover 14 is fixed at the bottom of the mounting plate 2. The protective cover 14 is located outside the air extraction fan group 3. Through the setting of the protective cover 14, it is avoided that mosquitoes in the kitchen waste enter the gas transmission pipe 4 through the mounting cover 1, and the mosquitoes and floating objects are filtered and isolated.

[0038] Check valves 15 for preventing gas backflow are installed in both the gas transmission pipe 4 and the connecting pipe 9. A control valve 16 is also installed on the connecting pipe 9. Through the setting of the check valves 15, it is avoided that the gas flows back in the gas transmission pipe 4 and the connecting pipe 9. At the same time, the control valve 16 can control the gas flow rate in the connecting pipe 9.

[0039] A plurality of mounting holes 17 are opened around the surface of the mounting cover 1. A sealing ring 18 is bonded to the bottom of the mounting cover 1. Through the setting of the mounting holes 17, it is convenient to install the mounting cover 1 on the kitchen waste treatment equipment. At the same time, with the cooperation of the sealing ring 18, the sealing performance between the mounting cover 1 and the kitchen waste treatment equipment is ensured, and the diffusion of the odor is avoided.

[0040] A sponge sheet 19 is provided inside the adsorption box 10. The adsorbent and the sponge sheet 19 are stacked alternately. The sponge sheet 19 can isolate the adsorbent and at the same time slow down the flow rate of the gas inside the adsorption box 10, ensuring that the adsorbent has enough time to adsorb harmful substances in the gas.

[0041] During specific use, the installation cover 1 is installed on the kitchen waste treatment equipment. At the same time, the air extraction fan group 3 is started to extract the odor emitted by the garbage in the kitchen waste treatment equipment, and then it is introduced into the liquid storage tank 6 inside the equipment box 5 through the air delivery pipe 4. The conveying motor 72 is started, and the conveying motor 72 drives the movable shaft 73 and the spiral blade 74 to rotate, enabling the synchronous conveyance of the gas and liquid conveyed into the cylindrical barrel 71, so that the microorganisms in the solution react with the organic substances in the gas. Then the gas diffuses upward from the air outlet 76 and is dispersed through the dispersion holes 13 on the fixing plate 12. At the same time, the stirring motor 81 is started, and the stirring motor 81 drives the stirring shaft 82 and the stirring blades 83 to disperse the gas floating on the solution, making the gas and the solution fully mixed to ensure that the odor-carrying organic substances are decomposed into odorless inorganic substances. Subsequently, the gas is introduced into the adsorption box 10 through the connecting pipe 9, and the harmful substances in the gas are adsorbed by the activated carbon adsorbent in the adsorption box 10, making the discharged gas odorless and harmless.

[0042] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
