Description

Technical Field

[0001] The present invention relates to the technical field of composting machines, in particular to a kitchen waste composting machine. Background Art

[0002] Kitchen waste refers to waste generated from daily life, food processing, catering services, and workplace dining. It includes discarded vegetable leaves, leftovers, leftover rice, fruit peels, eggshells, tea leaves, bones, and more. Its primary sources are household kitchens, restaurants, hotels, canteens, markets, and other food processing-related industries. Kitchen waste is one of the raw materials for ecological fertilizer, and as such, an increasing amount of it is being collected, processed, and utilized appropriately. However, unlike solid waste such as straw, human, livestock, and poultry manure, cake meal, agricultural and sideline products, and food processing, which are easily collected in large quantities, household kitchen waste is small in size and widely dispersed, making its total volume and collection difficult. Therefore, it is primarily disposed of along with other household waste through incineration or landfill, which is quite wasteful.

[0003] However, kitchen waste is prone to rotting and stinking, leading to the emergence of many household kitchen waste grinders on the market. These grinders grind the food waste into appropriate particles, which are then discharged into the sewer pipes along with the water, thereby improving the convenience and cleanliness of residents' lives. However, the ground material is likely to get stuck in the pipes, causing blockages, which is very troublesome.

[0004] Some households now use composting buckets or composters to compost kitchen waste for efficient utilization. This effectively solves the pipe blockage problem caused by food waste grinders and allows the fertilizer to be used for growing potted plants, vegetables, and fruits. However, composting buckets are slow and have a noticeable odor, making them unsuitable for use in residential areas with commercial housing. Purchasing a composter in conjunction with a food waste grinder is not only expensive but also requires considerable space and is very cumbersome.

[0005] Therefore, the research purpose of this invention is to design a kitchen waste composting machine that can realize household kitchen waste crushing, drying and composting, effectively solve the problems of pipe blockage in traditional kitchen waste treatment equipment, and directly process kitchen waste into usable fertilizer. The overall layout of the equipment is compact and exquisite, and it takes up little space. Summary of the Invention

When the movable parts move inward, they push the connecting parts upward and cooperate to pull the grinding tool holder to quickly disassemble the grinding tool holder and the connecting shaft.

[0009] The outer side of the upper part of the grinding knife seat is set in a cone shape, and a positioning kit for limiting the position of the button is fixedly installed by corresponding bolts. The outer side of the button is set in a stepped manner, and the positioning kit is sleeved on the outer side of the stepped part of the button and the top of the button extends outward and is set on the outer side of the positioning kit; a corresponding second elastic member is provided between the connecting member and the button, and a corresponding first groove is provided on the top of the connecting member. The second elastic member is embedded in the first groove. When the button is pressed to move downward, the second elastic member is compressed. After the pressure is withdrawn, the button is reset under the action of the elastic potential energy of the second elastic member.

[0010] The connecting part includes a shaft part and a sleeve part which are integrally formed in an upper and lower manner. The diameter of the sleeve part is larger than the diameter of the shaft part. A limiting part for limiting the first elastic part is fixedly provided on the top of the first elastic part on the grinding tool holder. The first elastic part is sleeved on the outside of the shaft part and its two ends are respectively abutted on the limiting part and the sleeve part; a corresponding embedded ring groove is recessed inwardly in the mounting hole of the grinding tool holder, and the limiting part includes a retaining spring clamped in the embedded ring groove and a gasket arranged on the retaining spring.

[0011] The lower part of the mounting hole and the lower outer side surface of the sleeve part are both in a matching constriction shape, and a through hole connected to the inner side of the sleeve part is installed on the sleeve part at the constriction, and the locking part is a steel ball rollingly installed in the through hole between the grinding tool holder and the sleeve part; when the connecting shaft is inserted into the grinding tool holder, the connecting shaft pushes the sleeve part to move upward and the first elastic part is compressed. After the connecting shaft is inserted into the grinding tool holder and is in place, the first elastic part resets and drives the sleeve part to move downward and be sleeved on the outside of the connecting shaft. The locking part is axially moved inwardly under the guidance of the inclined surface of the constriction inner of the mounting hole and is embedded in the embedding groove of the connecting shaft, so that the grinding tool holder and the connecting shaft are locked and connected.

[0012] The button is sleeve-shaped and the inner side of its lower part is a first inclined surface inclined inwardly. The periphery of the shaft part is provided with a corresponding second groove, and the second groove is respectively provided with a second inclined surface in the opposite direction of the inclination of the first inclined surface. The movable part is a steel ball movably installed between the limit part and the button; when the button moves downward, the movable part moves axially inwardly under the guidance of the first inclined surface and is embedded in the second groove. The movable part cooperates with the second inclined surface to push the connecting part upward, and the upward movement of the connecting part drives the locking part to move upward synchronously to unlock the grinding tool holder and the connecting shaft.

[0013] The exhaust filtering mechanism includes a first activated carbon filter element that is detachably mounted on the upper portion of the air guide channel and a second activated carbon filter element installed at the exhaust port in the shell. After the material in the mixing barrel is dried, crushed, and fermented with water in turn, the exhaust gas inside the mixing barrel is guided by the exhaust fan and is double-filtered by the first activated carbon filter element and the second activated carbon filter element in turn before being discharged outward.

[0014] The cover body is provided with an installation cavity for installing the water pump, and the installation cavity is provided with a diverter facing the water outlet of the mixing barrel, and the diverter is connected to the water outlet of the water pump; the water storage cylinder is transparent and a corresponding infrared sensor is provided on the side of its bottom. When the water amount in the water storage cylinder is lower than the set standard L, the infrared sensor signal is transmitted to the control system for an alarm reminder; the top of the water storage cylinder is respectively provided with corresponding water filling holes and water outlet holes, and the water filling holes and water outlet holes are respectively provided with corresponding opening and closing covers and anti-return parts, and the cover body is provided with a connecting vessel connected to the water pump; when the cover body is flipped down into place and closed with the shell, the water storage cylinder is connected to the water pump through the connecting vessel and the anti-return part.

[0015] A corresponding temperature and humidity sensor is provided at the air inlet of the air guide channel. When the temperature detected by the temperature and humidity sensor is not within the set range of 50~70°C, the heating mechanism is controlled by the control system to adjust the temperature up and down; when the temperature detected by the temperature and humidity sensor is lower than the set range of 50~60%, the water pump is controlled by the control system to start adding water to increase the humidity; the conduction mechanism includes a water collecting box arranged below the cooling mechanism, and the water collecting box is connected to the water pump through a corresponding water guide pipe and a constant flow valve. When the water pump is started, the water storage cylinder and the water collecting box are connected. When there is no liquid in the water collecting box, the constant flow valve automatically closes; a transverse conduction pipe arranged perpendicular to the air guide channel is installed between the air guide channel and the second activated carbon filter element. The cooling mechanism includes a dispersed temperature conducting member arranged at the end of the air guide channel and a semiconductor refrigeration plate in contact with the dispersed temperature conducting member. The longitudinal section of the dispersed temperature conducting member is W-shaped, and it is evenly distributed with many long air holes, and cooperates with the long air holes to form a grid shape.

[0016] The exhaust gas discharged from the mixing barrel is guided by the exhaust fan and circulated into the transverse conducting pipe after being filtered and cooled. The cooled exhaust gas makes the temperature in the transverse conducting pipe within the set range value T required for the sterilization action of the sterilization mechanism. The sterilization mechanism is an ozone generator installed on the outside of the transverse conducting pipe, and the ozone injection plate of the ozone generator is installed on the inner top of the transverse conducting pipe.

[0017] Advantages of the present invention: 1) Through reasonable layout and structural improvements, the present invention crushes, dries and composts kitchen waste to obtain directly usable solid ecological fertilizer. The mixing barrel and the air guide channel for exhaust are used to rationally partition the shell, thereby facilitating the compact installation of the crushing mechanism, heating mechanism, exhaust filter mechanism, humidification mechanism, cooling mechanism and sterilization mechanism, significantly reducing the size and occupied space of the equipment, and improving its functionality, thereby directly processing kitchen waste into usable fertilizer.

[0018] 2) Traditional food waste grinders have a fixed connection between the grinding blade and the mixing bowl. After a period of use, cleaning the mixing bowl can be difficult or inadequate, leading to mold and odor inside the mixing bowl, which in turn affects the quality of the compost. Therefore, the present invention incorporates a quick-release mechanism for detachably connecting the mixing bowl and the grinding blade holder. This ensures a secure mounting of the grinding blade while allowing for quick removal for thorough cleaning. The lower part of the mounting hole of the grinding knife seat and the lower outer side of the connecting piece movably installed in the mounting hole are set to a matching necking shape, and a corresponding through hole is set through the necking of the connecting piece, and a corresponding steel ball is movably installed in the through hole; when installing the grinding knife seat and the connecting shaft, it is only necessary to align the connecting piece with the connecting shaft and directly press down to apply force, and the connecting piece moves up and compresses the first elastic piece under the push of the connecting shaft; after the grinding knife seat and the connecting shaft are installed in place, the connecting piece rebounds and moves down under the action of the elastic potential energy of the first elastic piece and is sleeved on the connecting shaft, and the steel ball moves axially inward under the guidance of the necking bevel surface of the mounting hole and is buckled into the embedding groove of the connecting shaft, thereby locking and fixing the connection between the grinding knife seat and the connecting shaft. The installation method is simple and convenient, easy to operate, and the connection is firm to ensure the use of the blade, effectively improving the convenience and practical effect of installation.

[0019] 3) The present invention further provides a first inclined surface and a second inclined surface with opposite inclined directions on the button and the connecting member, and a moving member in the shape of a steel ball is movably installed between the first inclined surface and the second inclined surface of the button and the connecting member; during disassembly, the button is pressed down, and the moving member moves axially inward under the guidance of the first inclined surface, and the moving member contacts the second inclined surface of the connecting member. Due to the force decomposition, the connecting member receives an upward thrust and moves upward, and drives the locking member in the shape of a steel ball on the connecting member to move. During the upward movement of the locking member, its self-locking stroke can be released, thereby allowing the connecting member to disengage from the buckle of the connecting shaft. Then, the grinding knife seat is pulled upward at the same time, so that the disassembly can be completed easily and quickly, and the vertical force N applied to the button needs to ensure that the upward thrust on the connecting member is greater than the elastic potential energy of the first elastic member. It can be seen that the first elastic member can not only ensure that the connecting member can move down to engage the connecting shaft during installation, but also limit the force applied during disassembly, effectively protecting the quick release mechanism, avoiding touch-disconnection, and ensuring the stability of the connection.

[0020] 4) The present invention is used for convenient disassembly of the grinding blade by cooperating with the unlocking mechanism and the self-locking mechanism. Since the force continuously applied to the button needs to be greater than the vertical force N, and the base needs to be pulled synchronously to unlock and disassemble, otherwise the connecting member will be driven downward again by the reset force of the first elastic member to lock the connection, further ensuring the stability of the installation.

[0021] 5) The present invention utilizes activated carbon filters positioned at the front and rear ends of the exhaust gas, working in conjunction with the exhaust fan to deodorize and filter the exhaust gas. The exhaust fan also serves to guide the gas flow, ensuring that the gas is evenly transported and cooled by the cooling mechanism, thereby reducing the temperature of the exhaust gas, enhancing the user experience and effectiveness of the present invention. Furthermore, a corresponding transverse conducting pipe is positioned vertically at the outlet end of the air guide channel, providing a relatively independent space for the sterilization mechanism to operate, facilitating full contact between the ozone generated by the ozone generator and the exhaust gas, thereby improving the sterilization effect. Furthermore, the temperature of the transverse conducting pipe decreases during the transport of the cooled exhaust gas, thereby providing a suitable temperature environment for the ozone generator's sterilization operation. This provides the ozone generator with the required temperature environment and spatially enclosed conditions for sterilization, ensuring smooth sterilization and further enhancing the sterilization effect. Furthermore, the final activated carbon filter is installed at the rear of the ozone generator, further enhancing the filtration efficiency of the exhaust gas during food waste treatment and effectively addressing the odor problem of ozone generated by the ozone sterilization mechanism, thereby enhancing the user experience of the present invention.

[0022] 6) The cooling mechanism of the present invention is composed of a semiconductor refrigeration plate and a dispersed heat conducting member that are in contact with each other, and the dispersed heat conducting member is evenly distributed with many long air holes, which cooperate with the long air holes to form a grid shape. In this way, on the basis of ensuring the smooth circulation of exhaust gas, the dispersed heat conducting member can effectively conduct and disperse the temperature of the semiconductor refrigeration plate, ensuring that the exhaust gas can fully contact the dispersed heat conducting member for cooling, thereby improving the cooling effect and efficiency. Furthermore, the longitudinal section of the dispersed heat conducting member is set to a W-shaped structure, so that the water droplets condensed on the dispersed heat conducting member due to the cooling of the exhaust gas can be guided and gathered along its inclined surface, and fall under the action of gravity and gather on the water collecting box below; and through the conduction mechanism formed by the water collecting box, the water pipe and the constant flow valve, it is connected to the water pump to discharge the condensed water in time to ensure the dryness in the equipment and to increase the service life of the equipment; and composting causes the water content of the exhaust gas to increase significantly, and the cooling mechanism is used to condense the gaseous water in the exhaust gas. The liquid water is recycled into the compost through the water pump, thereby effectively achieving the effect of saving water resources. By adding a set flow valve between the water collecting box and the water pump, the water pump can simultaneously pump liquid from the water collecting box and the water storage cylinder when it is started. When there is no water in the water collecting box, the connection between the water collecting box and the water pump is disconnected by controlling the fixed flow valve. Not only can the water in the water collecting box be pumped out in time for use, ensuring a dry use environment, but it can also avoid the problem of turbulence on the flow of exhaust gas when pumping without water, thereby improving the practical effect of the present invention.

[0023] 7) The present invention adds a sterilization mechanism and a cooling mechanism on the basis of the exhaust filter mechanism, and sends the exhaust gas filtered and guided by the exhaust filter mechanism into the cooling mechanism to reduce the temperature of the exhaust gas discharged externally. The sterilization mechanism is then used to kill harmful bacteria in the exhaust gas, thereby effectively preventing bacteria from growing at the exhaust port of the food waste disposer due to high temperature and high humidity.

[0024] 8) The humidification mechanism of the present invention comprises a water storage cylinder and a water collection box, forming a dual water inlet channel. The detachable water storage cylinder facilitates easy access for water addition. The water storage cylinder and the cover are each provided with a corresponding manifold and a check member. After the cover is flipped downward and connected to the housing, the manifold is inserted into the check member, establishing communication between the water pump and the water storage cylinder. The water pump then pumps water from the water storage cylinder to facilitate composting. Humidification of compost increases the moisture content of the exhaust gas, which can easily increase humidity in the area near the exhaust port. This not only affects the environment and service life of the equipment, but also causes high humidity in the area, making it prone to mold. The addition of a cooling mechanism allows the gaseous water in the exhaust gas to condense into liquid water, thereby controlling the humidity and moisture content of the exhaust gas and improving the practical effects of the present invention. A water collecting box is provided below the cooling mechanism, and the W-shaped setting of the non-standard dispersed temperature conducting member is used to guide and gather the condensed water into the water collecting box, and then the water collecting box is reused for compost humidification through the cooperation of the conducting mechanism and the water pump. This not only effectively realizes the recycling of water and saves water resources, but also prevents the service life of the equipment from being shortened due to the accumulation of condensed water, and prevents the problem of easy mold in the area where the composter is located due to the high water content and temperature of the exhaust gas, thereby further improving the practical effect of the present invention.

DETAILED DESCRIPTION

[0034] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the embodiments and the accompanying drawings: refer to Figure 1-8 , a food waste composting machine, comprising: A housing 1, the top of which is reversibly provided with a corresponding cover 9; The crushing mechanism 2 comprises a mixing barrel 201 detachably mounted on one side of the housing 1 , and a grinding blade holder 203 is conveniently mounted and disassembled on the bottom of the mixing barrel 201 via a corresponding quick-release mechanism 202 ; The heating mechanism 3 is installed at the bottom of the mixing barrel 201 and is used to heat the kitchen waste in the mixing barrel 201; The exhaust filter mechanism 4 includes an air guide channel 401 connecting the air outlet of the mixing drum 201 and the exhaust port of the housing 1, an exhaust fan 402 and at least one deodorizing filter element disposed within the air guide channel 401, and the air guide channel 401 divides the other side of the housing 1 where the mixing drum 201 is not disposed into different installation areas; The humidification mechanism 5 includes a water pump 501 and a water storage cylinder 502 that is detachably mounted in an installation area where no exhaust port is provided. When the cover 9 is flipped downward and closed with the housing 1, the mixing barrel 201 is closed, and the water storage cylinder 502 is connected to the water pump 501 to add water to humidify the dried kitchen waste in the mixing barrel 201. The cooling mechanism 6 and the sterilization mechanism 7 are installed in series in an installation area provided with an exhaust port, and are installed in sequence on the rear side of the exhaust fan 402. The cooling mechanism 6 is used to reduce the outlet temperature of the exhaust gas and provide a temperature environment for the sterilization mechanism 7 to perform sterilization operations. The water droplets condensed by the cooling mechanism 6 are guided into the mixing barrel 201 through the conducting mechanism 8 at the bottom thereof and the water pump 501.

[0035] Through reasonable layout and structural improvements, the present invention crushes, dries and composts kitchen waste to obtain solid ecological fertilizer that can be directly used. The mixing barrel 201 and the air guide channel 401 for exhaust are used to reasonably partition the shell 1, thereby facilitating the compact installation of the crushing mechanism 2, the heating mechanism 3, the exhaust filter mechanism 4, the humidifying mechanism 5, the cooling mechanism 6 and the sterilizing mechanism 7, significantly reducing the size and occupied space of the equipment, and improving its functionality, so that kitchen waste can be directly processed into usable fertilizer.

[0036] The quick release mechanism 202 includes A connecting shaft 221 is fixedly mounted on the bottom of the mixing barrel 201, and a corresponding embedding groove 2211 is provided inwardly on its upper portion; a mounting hole is provided on the grinding blade holder 203, which is sleeved on the connecting shaft 221 and the upper portion of the connecting shaft 221 is inserted into the mounting hole; a corresponding grinding blade is fixedly mounted on the periphery of the grinding blade holder 203, and a grinding member compatible with the grinding blade is detachably provided on the inner side wall of the mixing barrel 201; The self-locking assembly 223 includes a connecting member 2232 that is movably mounted in the mounting hole of the grinding tool holder 203 via a corresponding first elastic member 2231, and a corresponding locking member 2233 is axially mounted on the connecting member 2232. When the grinding tool holder 203 and the connecting shaft 221 are sleeved together, the connecting member 2232 is abutted and embedded between the connecting shaft 221 and the grinding tool holder 203 under the elastic potential energy of the first elastic member 2231, and the locking member 2233 is axially moved inward to be clamped in the embedding groove 2211, thereby locking the connecting shaft 221 and the grinding tool holder 203. The unlocking assembly 224 includes several movable parts 2242 arranged in the mounting hole and driven by corresponding buttons 2241 to move axially inward synchronously. When the movable parts 2242 move inward, they push the connecting part 2232 upward and cooperate to pull the grinding tool holder 203, so that the grinding tool holder 203 and the connecting shaft 221 are quickly disassembled.

[0037] The outer side of the upper part of the grinding knife seat 203 is set in a cone shape, and a positioning kit 225 for limiting the setting of the button 2241 is fixed by corresponding bolts. The outer side of the button 2241 is set in a stepped manner. The positioning kit 225 is sleeved on the outer side of the stepped portion of the button 2241 and the top of the button 2241 extends outward and is set on the outer side of the positioning kit 225; a corresponding second elastic member 2243 is provided between the connecting member 2232 and the button 2241, and a corresponding first groove is provided on the top of the connecting member 2232. The second elastic member 2243 is embedded in the first groove. When the button 2241 is pressed to move downward, the second elastic member 2243 is compressed. After the pressure is withdrawn, the button 2241 is reset under the action of the elastic potential energy of the second elastic member 2243.

[0038] The connecting member 2232 includes a shaft portion 22321 and a sleeve portion 22322 integrally formed in an upper and lower manner. The diameter of the sleeve portion 22322 is larger than the diameter of the shaft portion 22321. A limiting member 222 for limiting the first elastic member 2231 is fixedly provided on the top of the first elastic member 2231 on the grinding tool holder 203. The first elastic member 2231 is sleeved on the outer side of the shaft portion 22321 and its two ends respectively abut against the limiting member 222 and the sleeve portion 22322; a corresponding embedded ring groove is recessed inwardly in the mounting hole of the grinding tool holder 203, and the limiting member 222 includes a retaining spring 2221 clamped in the embedded ring groove and a gasket 2222 arranged on the retaining spring 2221.

[0039] The lower part of the mounting hole and the lower outer side surface of the sleeve portion 22322 are both in a matching constriction shape. A through hole communicating with the inner side of the sleeve portion 22322 is installed at the constriction on the sleeve portion 22322. The locking member 2233 is a steel ball rollingly installed in the through hole between the grinding tool holder 203 and the sleeve portion 22322. When the connecting shaft 221 is inserted into the grinding tool holder 203, the connecting shaft 221 pushes the sleeve portion 22322 to rotate. 2322 moves up and the first elastic member 2231 is compressed. After the connecting shaft 221 is inserted into the grinding tool holder 203 and is in place, the first elastic member 2231 resets and drives the sleeve portion 22322 to move down and be sleeved on the outside of the connecting shaft 221. The locking member 2233 is guided by the inner inclined surface of the shrinkage of the mounting hole and moves axially inward to be embedded in the embedding groove 2211 of the connecting shaft 221, thereby locking the grinding tool holder 203 and the connecting shaft 221.

[0040] The pulverizing blade and mixing barrel 201 of a traditional food waste pulverizer are fixedly connected. After a period of use, the mixing barrel 201 is difficult to clean or not cleaned properly, causing the inside of the food waste mixing barrel 201 to become moldy and smelly, which in turn affects the quality of the compost. Therefore, the present invention provides a corresponding quick-release mechanism 202 for detachably connecting the mixing barrel 201 and the grinding blade holder. In this way, while ensuring that the grinding blade 2031 is firmly installed, the grinding blade 2031 can be quickly removed for thorough cleaning. The lower portion of the mounting hole of the grinding blade holder 203 and the lower outer portion of the connecting member 2232 movably installed in the mounting hole are configured to have matching constrictions, and corresponding through-holes are provided through the constrictions of the connecting member 2232, in which corresponding steel balls are movably installed. When installing the grinding blade holder 203 and the connecting shaft 221, it is only necessary to align the connecting member 2232 with the connecting shaft 221 and directly press down. The connecting member 2232 moves upward under the push of the connecting shaft 221 to compress the first elastic member 2231. After the grinding knife seat 203 and the connecting shaft 221 are installed in place, the connecting piece 2232 rebounds and moves downward under the action of the elastic potential energy of the first elastic piece 2231 and is sleeved on the connecting shaft 221. The steel ball moves axially inward under the guidance of the shrinkage bevel surface of the installation hole and is buckled into the embedding groove 2211 of the connecting shaft 221, thereby locking and fixing the grinding knife seat 203 and the connecting shaft 221. The installation method is simple and convenient, easy to operate, and the connection is firm to ensure the use of the blade, effectively improving the convenience and practical effect of installation.

[0041] The button 2241 is sleeve-shaped and the inner side of its lower part is a first inclined surface 22411 inclined inwardly. The periphery of the shaft part 22321 is provided with a corresponding second groove, and the second groove is respectively provided with a second inclined surface 22323 in the opposite direction of the inclination of the first inclined surface 22411. The movable member 2242 is a steel ball movably installed between the limit member 222 and the button 2241; when the button 2241 moves downward, the movable member 2242 moves axially inwardly under the guidance of the first inclined surface 22411 and is embedded in the second groove. The movable member 2242 cooperates with the second inclined surface 22323 to push the connecting member 2232 upward, and the upward movement of the connecting member 2232 drives the locking member 2233 to move upward synchronously to unlock the grinding tool holder 203 and the connecting shaft 221.

[0042] The present invention further provides a first inclined surface 22411 and a second inclined surface 22323 with opposite inclined directions on the button 2241 and the connecting member 2232, and a moving member 2242 in the shape of a steel ball is movably installed between the button 2241 and the first inclined surface 22411 and the second inclined surface 22323 of the connecting member 2232; when disassembling, by pressing the button 2241, the moving member 2242 moves axially inward under the guidance of the first inclined surface 22411, and the moving member 2242 contacts the second inclined surface 22323 of the connecting member 2232. Due to the decomposition of the force, the connecting member 2232 receives an upward thrust and moves upward, thereby driving the steel ball-shaped locking member on the connecting member 2232 When the connecting member 2233 moves and the locking member 2233 moves upward, its self-locking stroke can be released, thereby disengaging the connecting member 2232 from the buckle of the connecting shaft 221. Then, the grinding knife holder 203 is pulled upward at the same time to complete the disassembly easily and quickly, and the vertical force N applied to the button 2241 needs to ensure that the upward thrust on the connecting member 2232 is greater than the elastic potential energy of the first elastic member 2231. It can be seen that the first elastic member 2231 can not only ensure that the connecting member 2232 can move downward to buckle the connecting shaft 221 during installation, but also limit the amount of force applied during disassembly, effectively protecting the quick-release mechanism, avoiding disconnection by touch, and ensuring the stability of the connection.

[0043] The present invention cooperates with the unlocking mechanism 224 and the self-locking mechanism 223 to conveniently disassemble the grinding blade 2031. Since the force continuously applied to the button 2241 needs to be greater than the vertical force N, and the base needs to be pulled synchronously to unlock and disassemble it, otherwise the connecting member 2232 will be driven downward again under the reset force of the first elastic member 2231 to lock the connection, further ensuring the stability of the installation.

[0044] The exhaust filtering mechanism 4 includes a first activated carbon filter element 403 detachably mounted on the upper portion of the air guide channel 401 and a second activated carbon filter element 404 installed at the exhaust port in the shell 1. After the material in the mixing barrel 201 is dried, crushed, and fermented with water, the exhaust gas inside the mixing barrel 201 is guided by the exhaust fan 402 and is double-filtered by the first activated carbon filter element 403 and the second activated carbon filter element 404 before being discharged outward.

[0045] The present invention deodorizes and filters the waste gas through the cooperation of the activated carbon filter element and the exhaust fan 402 arranged in the front and back, and uses the exhaust fan 402 to guide the gas, so that the gas is evenly transmitted and contacts with the cooling mechanism 6 for cooling, thereby reducing the temperature of the exhaust gas, improving the good experience and use effect of the present invention; and by vertically arranging the corresponding transverse conducting pipe 405 at the air outlet end of the air guide channel 401, a relatively independent space is provided for the operation of the sterilization mechanism 7, which facilitates the full contact of the ozone generated by the ozone generator with the waste gas, thereby improving the sterilization effect; furthermore, the temperature of the transverse conducting pipe 405 is reduced during the transmission of the cooled waste gas, thereby providing a suitable temperature environment for the sterilization action of the ozone generator, thereby providing the ozone generator with the temperature environment and space closure conditions required for the sterilization action, to ensure the smooth completion of the sterilization action, and further improve the sterilization effect. In addition, the last activated carbon filter is installed on the rear side of the ozone generator, which can further improve the filtering effect of the exhaust gas during the kitchen waste treatment process, and can also effectively solve the odor problem of ozone generated by the addition of the ozone sterilization mechanism 7, thereby improving the good experience of the present invention.

[0046] The cover body 9 is provided with an installation cavity for installing the water pump 501, and the installation cavity is provided with a diverter 503 for discharging water facing the mixing barrel 201, and the diverter 503 is connected to the water outlet of the water pump 501; the water storage cylinder 502 is transparent and a corresponding infrared sensor 504 is provided on the side of its bottom. When the water amount in the water storage cylinder 502 is lower than the set standard L, the infrared sensor 504 signal is transmitted to the control system for an alarm reminder; the top of the water storage cylinder 502 is respectively provided with corresponding water filling holes and water outlet holes, and the water filling holes and water outlet holes are respectively provided with corresponding opening and closing covers 505 and anti-return parts 506, and the cover body 9 is provided with a connecting vessel 507 connected to the water pump 501; when the cover body 9 is flipped down into place and closed with the shell 1, the water storage cylinder 502 is connected to the water pump 501 through the connecting vessel 507 and the anti-return part 506.

[0047] A corresponding temperature and humidity sensor is provided at the air inlet of the air guide channel 401. When the temperature detected by the temperature and humidity sensor is not within the set range of 50~70°C, the heating mechanism 3 is controlled by the control system to adjust the temperature up and down; when the temperature detected by the temperature and humidity sensor is lower than the set range of 50~60%, the water pump 501 is controlled by the control system to start adding water to increase the humidity; the conduction mechanism 8 includes a water collecting box 801 arranged below the cooling mechanism 6, and the water collecting box 801 is connected to the water pump 501 through a corresponding water pipe 802 and a constant flow valve. When the water pump 501 is started, the water storage cylinder 502 and the water collecting box 801 are connected. When there is no liquid in the water collecting box 801, the constant flow valve is automatically closed.

[0048] The air guide channel 401 and the second activated carbon filter element 404 are connected by a transverse conducting pipe 405 arranged perpendicular to the air guide channel 401. The cooling mechanism 6 includes a dispersed heat conducting component 601 arranged at the end of the air guide channel 401 and a semiconductor refrigeration plate 602 in contact with the dispersed heat conducting component 601. The longitudinal section of the dispersed heat conducting component 601 is a W-shaped structure, and it is evenly distributed with many long air holes, which cooperate with the long air holes to form a grid shape.

[0049] The humidification mechanism 5 of the present invention is composed of a water storage cylinder 502 and a water collection box 801, forming a dual water inlet channel. The detachable water storage cylinder 502 is convenient for people to take and add water, and the water storage cylinder 502 and the cover body 9 are respectively provided with corresponding connecting pipes 507 and check pieces 506. After the cover body 9 is turned downward and connected to the housing 1, its connecting pipe 507 is inserted into the check piece 506, so that the water pump 501 and the water storage cylinder 502 are connected. Then, the water pump 501 pumps water from the water storage cylinder 502 to promote the completion of composting. Since compost humidification increases the water content of the exhaust gas, it is easy to increase the humidity of the space near the exhaust port after discharge, which not only affects the environment of the equipment and shortens its service life, but also causes the high humidity in the area to easily cause mold. The added cooling mechanism 6 can also condense the gaseous water in the exhaust gas into liquid water, thereby controlling the humidity and water content of the exhaust gas, thereby improving the practical effect of the present invention. A water collecting box 801 is provided below the cooling mechanism 6. The W-shaped setting of the non-standard dispersed temperature conducting member 601 causes the condensed water to be diverted and gathered into the water collecting box 801. The water collecting box 801 is then reused for compost humidification through the cooperation of the conducting mechanism 8 and the water pump 501. This not only effectively realizes the recycling of water and saves water resources, but also prevents the service life of the equipment from being shortened due to the accumulation of condensed water, and prevents the problem of mold in the area where the composter is located due to the high water content and temperature of the exhaust gas, thereby further improving the practical effect of the present invention.

[0050] The exhaust gas discharged from the mixing barrel 201 is guided by the exhaust fan 402 and flows into the transverse conducting pipe 405 after filtering and cooling. The cooled exhaust gas makes the temperature in the transverse conducting pipe 405 within the set range value T required for the sterilization mechanism 7 to perform the sterilization action. The sterilization mechanism 7 is an ozone generator installed on the outside of the transverse conducting pipe 405, and the ozone injection plate of the ozone generator is installed on the inner top of the transverse conducting pipe 405.

[0051] The present invention adds a sterilization mechanism 7 and a cooling mechanism 6 on the basis of the exhaust filter mechanism 4, and sends the exhaust gas filtered and guided by the exhaust filter mechanism 4 into the cooling mechanism 6 to reduce the temperature of the exhaust gas discharged externally, and then uses the sterilization mechanism 7 to kill harmful bacteria in the exhaust gas, thereby effectively preventing bacteria from growing at the exhaust port of the food waste disposer due to high temperature and high humidity.

[0052] The cooling mechanism 6 of the present invention consists of a contacting and connected semiconductor cooling plate 602 and a dispersed heat conducting member 601. The dispersed heat conducting member 601 is evenly distributed with numerous long ventilation holes that form a grid-like pattern. This ensures smooth exhaust gas flow while the dispersed heat conducting member 601 effectively conducts and disperses the heat from the semiconductor cooling plate 602, ensuring sufficient contact and cooling of the exhaust gas. This maximizes contact with the dispersed heat conducting member, thereby improving cooling effectiveness and efficiency. Furthermore, the longitudinal section of the dispersed heat conducting member 601 is set to a W-shaped structure, so that the water droplets condensed on the dispersed heat conducting member 601 due to the cooling of the exhaust gas can be guided and gathered along its inclined surface, and fall under the action of gravity and gather on the water collecting box 801 below; and the conduction mechanism 8 formed by the water collecting box 801, the water pipe 802 and the constant flow valve is connected to the water pump 501 to discharge the condensed water in time to ensure the dryness in the equipment and to improve the service life of the equipment; and composting causes the water content of the exhaust gas to increase significantly, and the cooling mechanism 6 is used to condense the gaseous water in the exhaust gas into liquid water. The water is recycled into the compost through the water pump 501, thereby effectively achieving the effect of saving water resources. By adding a set flow valve between the water collecting box 801 and the water pump 501, when the water pump 501 is started, liquid is simultaneously pumped from the water collecting box 801 and the water storage cylinder 502. When there is no water in the water collecting box 801, the connection between the water collecting box 801 and the water pump 501 is disconnected by controlling the fixed flow valve. Not only can the water in the water collecting box 801 be promptly pumped out for use, ensuring a dry use environment, but also the problem of turbulence on the flow of exhaust gas when pumping without water can be avoided, thereby improving the practical effect of the present invention.
