[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1 In this embodiment, a fermentation chamber for a food waste treatment device is used to clean up the food waste remaining at the bottom of the fermentation chamber body 2, so as to facilitate subsequent fermentation treatment.

[0028] It includes a support frame 1, a fermentation chamber body 2, a cover plate 3, a discharge pipe 4, and a pushing component 5; the fermentation chamber body 2 is installed inside the support frame 1, and the cover plate 3 is installed on the top of the fermentation chamber body 2 by a hinge to control the opening and closing of the fermentation chamber body 2.

[0029] The discharge pipe 4 is connected to the left side of the fermentation chamber body 2, and the input end of the discharge pipe 4 is flush with the bottom wall of the fermentation chamber body 2; the bottom of the fermentation chamber body 2 protrudes downward to form a protrusion, and the cross-sectional shape of the left side of the protrusion is semi-circular; the push component 5 is set inside the fermentation chamber body 2.

[0030] When it is necessary to discharge the kitchen waste in the fermentation chamber body 2, the operation of the pushing component 5 pushes the kitchen waste remaining at the bottom of the fermentation chamber body 2 toward the discharge pipe 4, so that the kitchen waste remaining at the bottom of the fermentation chamber body 2 can be pushed into the discharge pipe 4 and output from the discharge pipe 4.

[0031] Please see Figure 2 In order to facilitate the pushing of the kitchen waste remaining at the bottom of the fermentation chamber body 2 into the discharge pipe 4, the pushing component 5 in this embodiment includes a rotating shaft 501 rotatably connected between the left and right sides of the inner wall of the fermentation chamber body 2. Several transmission shafts 502 are provided on the outside of the rotating shaft 501. A spiral blade 503 is installed at the end of the transmission shaft 502 away from the rotating shaft 501. The spiral blade 503 fits against the inner peripheral wall of the protrusion. A drive structure that is connected to the rotating shaft 501 is provided on the support frame 1.

[0032] In actual use, the drive structure drives the rotating shaft 501 to rotate, which in turn drives the transmission shaft 502 and the spiral blade 503 on its outer side to rotate. During the rotation of the spiral blade 503, the kitchen waste remaining on the bottom wall of the fermentation chamber body 2 moves along the spiral blade 503 toward the discharge pipe 4, thereby pushing the kitchen waste located on the bottom wall of the fermentation chamber body 2 into the interior of the discharge pipe 4.

[0033] Furthermore, in this embodiment, the rotating shaft 501 is a stainless steel tube that is hollow inside and missing its right end face. The inside of the drive shaft 502 is hollow and is connected to the drive shaft 502. Several exhaust holes are opened on the outside of the drive shaft 502. The right end of the rotating shaft 501 is rotatably connected to the connecting pipe 504 through a sealed bearing. The connecting pipe 504 is connected to the external oxygen supply equipment.

[0034] In actual use, oxygen can be introduced into the connecting pipe 504 through the oxygen supply equipment, and the oxygen can be transported to the inside of the rotating shaft 501 and the drive shaft 502 through the connecting pipe 504. The oxygen can be discharged into the inside of the fermentation chamber body 2 through the exhaust hole on the outside of the drive shaft 502, so as to provide oxygen to the microorganisms inside the fermentation chamber body 2.

[0035] In addition, the rotating shaft 501 and the transmission shaft 502 can be driven by the drive structure to rotate, so as to stir the kitchen waste inside the fermentation chamber body 2, and continuously release oxygen during the stirring process, so as to provide oxygen to the microorganisms in the fermentation chamber body 2.

[0036] In summary, by using the drive structure to drive the rotating shaft 501 and the transmission shaft 502 to rotate, this process can not only effectively stir the kitchen waste in the fermentation chamber body 2, but also continuously release oxygen while stirring, ensuring that the microorganisms in the fermentation chamber body 2 can obtain a comprehensive and uniform oxygen supply.

[0037] In detail, the drive structure includes a motor 505, two sprockets 506 and a chain 507; the motor 505 is mounted on the support frame 1, the two sprockets 506 are respectively sleeved on the outside of the output end of the motor 505 and the outside of the rotating shaft 501, and the chain 507 is connected to the outside of the two sprockets 506.

[0038] In actual use, the output end of the motor 505 rotates, thereby driving the sprocket 506 on its outer side to rotate. Through the transmission of the chain 507, another sprocket 506 is simultaneously rotated, thereby driving the shaft 501 in the other sprocket 506 to rotate.

[0039] Please see Figure 3 In order to purify the waste gas generated during fermentation, the fermentation chamber of the kitchen waste treatment device in this embodiment also includes a purification component 6. The purification component 6 includes a box 601 installed on the cover plate 3 and an air inlet pipe 602 installed inside the cover plate 3. The other end of the air inlet pipe 602 is connected to the box 601. Inside the box 601, a first adsorption layer 603, a second adsorption layer 604 and a third adsorption layer 605 are installed sequentially from left to right. An exhaust pipe 606 is connected to the right side of the box 601.

[0040] It should be noted that the first adsorption layer 603, the second adsorption layer 604, and the third adsorption layer 605 are respectively an activated carbon particle layer, a zeolite particle layer, and a ceramic particle layer.

[0041] In actual use, the waste gas generated during fermentation is first guided into the chamber 601 installed on the cover plate 3 through the air inlet pipe 602. Inside the chamber 601, the waste gas passes through three different adsorption layers for purification. The first layer is an activated carbon granule layer, which is mainly used to adsorb organic pollutants and some odors in the waste gas. The second layer is a zeolite granule layer, which can further adsorb and separate harmful gas molecules in the waste gas. The third layer is a ceramic granule layer, which serves as the final filter layer and can remove residual fine particles and odors, thereby improving the purification effect. After being treated by these three adsorption layers, the purified gas is discharged through the exhaust pipe 606 on the right side of the chamber 601, thus achieving effective purification of fermentation waste gas and reducing environmental pollution.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
