A composting machine sensor anti-pollution air duct structure

Abstract

This utility model discloses a pollution-proof air duct structure for a composting machine sensor, including a first air duct shell. A blower is installed on one side of the first air duct shell. An inwardly extending protrusion is provided at the air inlet end of the first air duct shell opposite to the blower. The protrusion has at least one through hole. A sensor is installed on the outside of the first air duct shell. The sensor probe is placed in the through hole. Since the source of suction comes from the blower, the airflow entering the air duct will deviate towards the blower as it gets closer to the air inlet end. The sensor probe is located on the side opposite to the air inlet end of the blower and is also shielded by the protrusion. The sensor probe will not protrude from the protrusion, which can greatly reduce contact with the airflow and thus reduce the adhesion of dust, water droplets and other substances to the probe.

Description

Technical Field

[0001] This utility model belongs to the technical field of kitchen waste treatment equipment, specifically a pollution prevention air duct structure for a composting machine sensor. 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] 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 step. Usually, the sensor probe needs to be inserted into the air duct to detect the problem. However, during the air extraction process, small foreign objects, oil stains, and water droplets can enter the air duct with the airflow and adhere to the sensor probe, causing the sensor to detect large deviations or become ineffective. Utility Model Content

[0004] The purpose of this invention is to provide a pollution-proof air duct structure for a composting machine sensor, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0007] In a further technical solution, the side wall of the first air duct housing is provided with a mounting groove for mounting sensors.

[0008] A further technical solution is that a bracket for fixing a blower is installed on the first air duct housing, and the bracket is used to install a second air duct housing. One end of the second air duct housing corresponds to the air outlet end of the blower, and the other end of the second air duct housing is connected to the odor removal component.

[0009] A further technical solution is that the odor removal component includes a housing, which has an activated carbon box inside, and an openable exhaust grille is provided at the end of the housing away from the second air duct shell.

[0010] The exhaust grille and the activated carbon box are provided with a sealing structure one at one end, and the activated carbon box and the shell are provided with a sealing structure two.

[0011] In a further technical solution, an end cap is detachably connected to the activated carbon box.

[0012] In a further technical solution, the activated carbon box is provided with several exhaust holes at one end corresponding to the exhaust grille, and the end near the second air duct shell is recessed inward to form a boss, and several air inlets are provided on the outer periphery of the boss.

[0013] In a further technical solution, the first air inlet is an elongated "L" shape, and a support portion corresponding to the first air inlet is provided in the groove of the boss.

[0014] In a further technical solution, the upper end of the activated carbon box is provided with two clearance positions.

[0015] 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.

[0016] The beneficial effects of this utility model are:

[0017] In the operation of this invention, since the source of suction comes from the blower, the airflow that enters the air duct will deviate towards the direction of the blower the closer it is to the air intake end of the blower. The sensor probe is set on the opposite side of the air intake end of the blower and is also provided with a protrusion as a shield. The sensor probe will not protrude from the protrusion, which can greatly reduce the contact with the airflow and thus reduce the adhesion of dust, water droplets and other substances to the probe.

Detailed Implementation

[0024] 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.

[0025] Please refer to Figure 1-4 ;

[0026] The air duct structure described in this utility model is applied in a composting machine to prevent the sensor 3 from being affected during exhaust. Specifically, it includes a first air duct housing 1, a blower 2 installed on one side of the first air duct housing 1, and an inwardly extending protrusion 11 located at the air inlet end of the first air duct housing 1 opposite to the blower 2. The protrusion 11 has at least one through hole 12. The sensor 3 is installed on the outside of the first air duct housing 1, and the probe of the sensor 3 is placed in the through hole 12. In this embodiment, the first air duct housing 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.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] Preferably, a mounting groove 13 is provided on the side wall of the first air duct housing 1, and 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.

[0031] 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 connected to the odor removal component 6.

[0032] 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 to set a sealing gasket. Through the above structure, the airflow can be smoothly guided into the odor removal component 6, and then the odor removal component 6 removes the odor in the gas before it is discharged to the outside.

[0033] One embodiment of the odor removal component 6 specifically includes a housing 61, which houses an activated carbon box 62. The housing 61 has an air inlet and an air outlet. The air outlet, i.e., the end of the housing 61 away from the second air duct housing 5, is provided with an openable exhaust grille 63. Of course, a sealing structure (not shown) is also provided between the exhaust grille 63 and the housing 61 to ensure that gas is output from the exhaust grille 63. In addition, the air inlet is connected to the second air duct housing 5. A sealing structure 64 is provided between the end of the internal activated carbon box 62 and the housing 61. Preferably, a first sealing gasket is provided at the bottom of the activated carbon box 62, and a second sealing gasket is provided on the inside of the housing 61. When the exhaust grille 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. The sealing structure 64 works on the same principle.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] Furthermore, the activated carbon box 62 is provided with a plurality of exhaust holes 621 at one end corresponding to the exhaust grille 63, and the end near the second air duct housing 5 is recessed inward to form a protrusion 622. A plurality of air inlets 623 are provided on the outer periphery of the protrusion 622. In this embodiment, the diameter of the activated carbon particles is smaller than that of the exhaust holes 621 and the air inlets 623. Of course, the diameters of the exhaust holes 621 and the air inlets 623 are also relatively small. The activated carbon particles are closely packed together under the action of mutual friction, thus reducing and preventing the activated carbon particles from falling out.

[0038] However, since it is placed vertically, it cannot completely prevent activated carbon particles from falling out of the air intake port 623. These fallen activated carbon particles will accumulate more and more over time, affecting the exhaust effect or producing abnormal noise. Therefore, the air intake port 623 has a lateral 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 downward by gravity, the lateral impact is greatly reduced, thereby further reducing the falling of activated carbon particles.

[0039] 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. The groove of the boss 622 is provided with a support part 624 corresponding to the air inlet 623. 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.

[0040] 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.

[0041] 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.

[0042] 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. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0043] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
