Description

Technical Field

[0001] This utility model belongs to the technical field of kitchen waste treatment equipment, specifically a structure for removing odors using activated carbon in a composting machine. Background Technology

[0002] The composting machine collects kitchen waste, dries it, and then uses the kitchen waste as fertilizer. During the drying process, an odor is generated. The gas is extracted from the inner cavity by a fan, filtered, and then discharged to the outside, as shown in the technical solution of the published technical document "CN 221706001 U, a kitchen waste drying processor".

[0003] Because the extracted airflow contains a strong odor, it needs to be purified before being discharged to the outside. The purification component usually uses activated carbon adsorption. However, activated carbon particles are very small, and to ensure smooth air intake, the diameter of the air intake hole is larger. The activated carbon particles are basically not loosened by mutual friction, but some dust and smaller activated carbon particles near the air intake hole will still fall out and into the air duct. These fallen activated carbon particles will accumulate more and more over time, and require disassembly to clean, affecting the exhaust effect or producing abnormal noise. Utility Model Content

[0004] The purpose of this invention is to provide an activated carbon deodorization structure for composting machines to solve the problems mentioned in the background art.

[0007] The activated carbon box has several exhaust holes at one end corresponding to the exhaust grille, and the end near the sealing structure two is recessed inward to form a boss. Several air inlets are provided on the outer periphery of the boss. Each air inlet is an elongated "L" shape, and a support part corresponding to the air inlet is provided in the groove of the boss.

[0008] In a further technical solution, the support portion covers the outer side of the first air inlet and forms a partition layer, and several second air inlets are provided on the support portion.

[0009] In a further technical solution, an end cap is detachably connected to the activated carbon box.

Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Please refer to Figure 1-4 ;

[0025] The structure of this utility model aims to minimize or avoid the falling of activated carbon particles into the air duct. It includes a housing 61, within which an activated carbon box 62 is housed. An openable exhaust grille 63 is located at one end of the housing 61. A sealing structure (not shown) is provided between the exhaust grille 63 and one end of the activated carbon box 62 to ensure gas output from the exhaust grille 63. A second sealing structure 64 is provided between the other end of the activated carbon box 62 and the housing 61. Preferably, a first sealing gasket is located at the bottom of the activated carbon box 62, and a second sealing gasket is located inside the housing 61. When the exhaust grille... When 63 is fastened, pressure is applied to the activated carbon box 62, causing the first and second sealing gaskets to be squeezed together to form a seal, and the same principle applies to the first sealing structure; an air inlet is provided near the second sealing structure 64; the activated carbon box 62 is provided with several exhaust holes 621 at one end corresponding to the exhaust grille 63, and the end near the second sealing structure 64 is recessed to form a boss 622, and several air inlets 623 are provided on the outer periphery of the boss 622. The air inlets 623 are long "L" shaped, and a support part 624 corresponding to the air inlets 623 is provided in the groove of the boss 622;

[0026] Activated carbon has a limited lifespan and needs to be replaced after a period of time. The activated carbon box 62 can be sold as an accessory. When it needs to be replaced, simply open the exhaust grille 63, take out the activated carbon box 62 located in the housing 61, put in the new activated carbon box 62, and finally close the exhaust grille 63. It is very convenient.

[0027] In another embodiment, the activated carbon box 62 is detachably connected to an end cap 627, which can be connected by screws. Generally, the activated carbon box 62 is made of plastic. For a more environmentally friendly approach, when replacement is needed, the end cap 627 is removed, the activated carbon inside is poured out, new activated carbon is added, and finally the end cap 627 is reinstalled.

[0028] Preferably, the upper end of the activated carbon box 62 is provided with two clearance positions 626, which are exactly the positions of the thumb and index finger, making it easy for people to take it out.

[0029] Since the activated carbon box 62 is placed vertically during use, it cannot completely prevent activated carbon particles from falling out of the air inlet 623. These fallen activated carbon particles will accumulate over time, affecting the exhaust effect or causing abnormal noise. Therefore, the air inlet 623 has a side-facing design, so that the orientation of the hole is not the same as the direction of gravity. Even if the activated carbon particles are squeezed downwards by gravity, the lateral impact is greatly reduced, thereby further reducing the falling of activated carbon particles.

[0030] Preferably, the air inlet 623 is an elongated "L" shape, which can increase the air intake area, but also increases the possibility of activated carbon particles falling off. Therefore, a support part 624 corresponding to the air inlet 623 is provided in the groove of the boss 622. Even if activated carbon particles fall off, some will fall into the support part 624, and fewer will fall into the second air duct housing 61.

[0031] It should be noted that after the activated carbon granules are filled, the mutual friction between the granules will limit their loosening. Moreover, since the gas contains moisture, the activated carbon shell 61 of the air inlet 623 will be the first to be moistened. Although it will dry later, it will strengthen the adhesion between the activated carbon granules near the air inlet 623, so it will not fall off easily. However, when it falls off, it will be in small pieces, so it will not fly away, but will fall into the support part 624.

[0032] Furthermore, the outer side of the air inlet 623 of the support part 624 is covered and forms a partition, which forms an "L" shape in cross-section. Several air inlets 625 are provided on the support part 624 to further prevent the activated carbon shell 61 from falling out. Preferably, the air inlets 623 and the air inlets 625 are staggered.

[0033] The air inlet of housing 61 is connected to the air duct assembly, where the sensor 3 probe is placed in the air duct assembly to detect the internal temperature and / or humidity. During the drying process, the humidity and temperature of the exhaust gas are detected to determine the operating status of the equipment and to make the next action. Usually, the sensor 3 probe needs to be inserted into the air duct to detect. However, during the air extraction process, small foreign objects, oil stains, and water droplets will enter the air duct with the airflow and adhere to the sensor 3 probe, causing the sensor 3 to detect a large deviation or become ineffective. Therefore, in this embodiment, an anti-contamination structure is provided for the sensor 3 probe.

[0034] More specifically, the anti-pollution structure includes a first air duct shell 1, a blower 2 is installed on one side of the first air duct shell 1, and an inwardly extending protrusion 11 is provided at the air inlet end of the first air duct shell 1 opposite to the blower 2. The protrusion 11 has at least one through hole 12. A sensor 3 is installed on the outside of the first air duct shell 1, and the probe of the sensor 3 is placed in the through hole 12. In this embodiment, the first air duct shell 1 should have an air duct for gas flow, and the air inlet end of the blower 2 and the protrusion 11 are respectively positioned opposite each other on both sides of the air duct.

[0035] In the actual structure, one end of the first air duct shell 1 is connected to the space of the composter used to store kitchen waste. When working, the space is heated to evaporate the moisture of the kitchen waste. At the same time, the blower 2 is turned on to draw the odors and moisture generated in the space into the air duct. Of course, some dust and fine floating particles will also be present.

[0036] Since the source of suction comes from blower 2, the airflow that is formed will deviate towards blower 2 as it gets closer to the air intake end of blower 2 after entering the air duct. The sensor 3 probe is set on the opposite side of the air intake end of blower 2 and is also provided with a protrusion 11 as a shield. The sensor 3 probe will not protrude from the protrusion 11, which can greatly reduce the contact with the airflow and thus reduce the adhesion of dust, water droplets and other substances to the probe.

[0037] It should be noted that although the sensor 3 probe has less contact with the airflow, the airflow is continuous and will still heat up the duct through heat transfer. Moreover, the airflow is filled with gas, and the disordered movement of moisture in the airflow will still fill the duct. Therefore, even if the sensor 3 probe does not have much contact with the airflow, it can still detect the temperature and humidity inside the duct. Of course, this design may cause a slight deviation in the final detection result, but the heating temperature itself will fluctuate, which can be solved by extending the heating time, but it will not affect the overall operation of the equipment.

[0038] In this embodiment of the present invention, a bracket 4 is installed on the first air duct housing 1, and the bracket 4 is used to install the second air duct housing 5. One end of the second air duct housing 5 corresponds to the air outlet end of the blower 2, and the other end of the second air duct housing 5 is sealed to the air inlet of the housing 61.

[0039] Because the extracted airflow contains a strong odor, a sealing structure is also required. The small blower 2 itself does not have a connecting installation structure. Therefore, the bracket 4 not only provides a mounting structure for the blower 2 to the first air duct housing 1, but also provides a connecting installation structure for the blower 2 to the second air duct housing 5. In addition, the most common sealing structure is to set a mutually fitting plug-in structure and a sealing gasket. Through the above structure, the airflow can be smoothly guided into the odor removal component, and then the odor removal component removes the odor from the gas before it is discharged to the outside.

[0040] Furthermore, a mounting groove 13 is provided on the side wall of the first air duct housing 1. The mounting groove 13 corresponds to the protrusion 11. The sensor 3 located on the outside is usually a PCB board and a data connector. The PCB board can be embedded in the installation, and the probe passes through the through hole 12, which can limit the installation of the sensor 3, making the installation more convenient.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
