Description

Technical Field

[0001] This application relates to the field of waste treatment technology, and in particular to a kitchen waste treatment device. Background Technology

[0002] Currently, the conventional methods for handling food waste mainly include: crushing and discharging it into the sewer, incineration, or transporting it to a large waste station for centralized composting.

[0003] Regarding the treatment method of pulverizing food waste and discharging it into the sewer, one existing technology for food waste disposers consists of a corrosion-resistant grinding chamber, all-stainless steel grinding hammers, and all-stainless steel grinding discs. It utilizes a high-speed rotating permanent magnet motor to drive the discs in the grinding chamber. Under centrifugal force, the food waste collides with each other, grinding it into fine particles that flow into the sewer system. However, discharging a large amount of pulverized organic matter into the sewer system significantly increases organic pollutant levels, placing a burden on domestic sewage treatment. Incinerating food waste is not an effective way to utilize it, leading to resource waste. The method of transporting food waste to large-scale waste stations for centralized composting also presents many problems: statistics show that the moisture content of general food waste is over 80%, which poses significant difficulties for collection, transportation, and treatment; furthermore, food waste has a high organic content, with protein, starch, and fat accounting for about 90% of its dry matter mass, making it prone to bacterial growth, decay, and foul odors, polluting the surrounding air environment.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this application and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this application is to provide a kitchen waste treatment device that can be used for household kitchen waste treatment, reduce the collection and transportation costs of kitchen waste, and prevent kitchen waste from polluting the surrounding air environment due to bacterial growth, rotting and foul odor.

[0006] To solve the above-mentioned technical problems, this application adopts the following technical solution:

[0007] A food waste treatment device includes an outer cylinder and an inner cylinder assembly disposed inside the outer cylinder. The inner cylinder assembly includes an openable and closable cover, a middle component, and a heat-conducting inner cylinder for containing food waste. The heat-conducting inner cylinder has a waste disposal port, and the middle component is at least partially embedded in the waste disposal port. The cover is closed onto the middle component and is sealed to the middle component. The middle component has a one-way air inlet and an air outlet communicating with the interior of the heat-conducting inner cylinder. The one-way air inlet is connected to outside air, and the air outlet is connected to a deodorizing mechanism.

[0008] The heat-conducting inner cylinder is equipped with a garbage shredding mechanism with adjustable rotation speed and a temperature and humidity sensor for detecting the temperature and humidity of the kitchen waste inside the inner cylinder; the heat-conducting inner cylinder is wrapped with a heating pad, and the heating pad is covered with an insulation layer; a weight sensor is provided at the bottom of the outer cylinder.

[0009] The temperature and humidity sensor and the weight sensor are respectively connected to the input terminal of the controller, and the output terminal of the controller is connected to the deodorization mechanism, the garbage crushing mechanism and the heating pad.

[0010] Furthermore, the deodorization mechanism includes an exhaust fan, an exhaust pipe, an activated carbon box, and an ozone generator. One end of the exhaust pipe is connected to the air outlet, and the other end is connected to the exhaust port of the exhaust fan via the activated carbon box. The ozone generator is placed in the exhaust pipe.

[0011] Furthermore, the exhaust pipe has a reciprocating bending structure and is attached to the outside of the outer cylinder.

[0012] Furthermore, the exhaust fan and the activated carbon box are located inside the outer cylinder, at the bottom of the heat-conducting inner cylinder.

[0013] Furthermore, the exhaust fan is provided with an exhaust fan housing, and the air inlet of the exhaust fan is provided with a rubber ring around its circumference; the exhaust fan housing is connected to the air outlet of the activated carbon box through a conical cylinder.

[0014] Furthermore, the waste shredding mechanism includes an adjustable speed motor located below the heat-conducting inner cylinder, a shredding blade assembly located inside the heat-conducting inner cylinder, and a gear transmission assembly connecting the adjustable speed motor and the shredding blade assembly. The gear transmission assembly includes a large gear that is driven by the shredding blade assembly, a small gear that is driven by the output shaft of the adjustable speed motor, and a chain that enables the drive connection between the large gear and the small gear.

[0015] Furthermore, the shredder assembly includes a horizontally arranged rotating shaft and multiple cutters staggered on the rotating shaft, and the bottom of the heat-conducting inner cylinder has an arc-shaped structure adapted to the cutting range of the cutters.

[0016] Furthermore, the cover assembly includes an outer cover plate, a first inner cover, and a second inner cover. The outer cover plate is rotatably connected to the first inner cover via a damping pivot. The second inner cover is disposed between the first inner cover and the intermediate component, and is sealed to the first inner cover and the intermediate component respectively.

[0017] Furthermore, the outer cylinder includes a bottom shell, and a front shell, a rear shell, a left side plate, and a right side plate respectively connected to the front, rear, left, and right sides of the bottom shell; multiple weight sensors are provided, and the multiple weight sensors are distributed at the bottom of the bottom shell.

[0018] Furthermore, an air intake box is provided at the one-way air intake, the air intake box including an air intake plate with multiple one-way air intake holes and a filter screen disposed on the air intake side of the air intake plate.

[0019] Compared with the prior art, the beneficial effects achieved by this application are as follows:

[0020] 1. The food waste treatment device provided in this application adopts a heat-conducting inner cylinder. Heating of the food waste inside the cylinder is achieved by wrapping a heating pad around the outer periphery of the inner cylinder. A temperature and humidity sensor is also installed, allowing the user to turn the heating pad on or off or adjust its power based on the current temperature and humidity of the food waste, ensuring that the moisture content and temperature of the food waste remain within a reasonable range, thereby improving the composting and fermentation efficiency. A weight sensor is installed at the bottom of the outer cylinder, allowing the user to adjust the rotation speed of the waste crushing mechanism and / or the heating pad based on the weight of the food waste. The power further improves the composting and fermentation efficiency of kitchen waste; the intermediate component is embedded in the waste inlet of the heat-conducting inner cylinder, which not only enhances the sealing performance between the heat-conducting inner cylinder and the cover, but also leaves space for the one-way air inlet. The one-way air inlet, together with the deodorization mechanism, can provide the necessary air for composting and fermentation of kitchen waste in the cylinder, and can also promptly expel the putrid and smelly air in the cylinder and deodorize it, thereby minimizing or even avoiding pollution of the surrounding air, making this device more suitable for places with higher air quality requirements such as homes and restaurants;

[0021] 2. The exhaust pipe of the deodorization mechanism is designed with a reciprocating bending structure to extend the exhaust path as much as possible within a limited space, thereby increasing the treatment time and effect of the putrid and smelly air. The exhaust pipe is attached to the outside of the outer cylinder, which reduces the space occupied inside the outer cylinder and makes it easier to clean and maintain the exhaust pipe later, as well as replace other related components (such as ozone generator).

[0022] 3. The rotating shaft in the shredder assembly is horizontally set, and the bottom of the heat-conducting inner cylinder is set as an arc-shaped structure adapted to the cutting area of ​​the cutter. Compared with the square structure, the arc-shaped structure is not only easier to clean, but also can prevent food waste from accumulating in the corners of the heat-conducting inner cylinder. In addition, the horizontal setting of the rotating shaft, compared with the vertical setting, can lower the center of gravity of the entire food waste treatment device and increase the stability of the food waste treatment device during operation.

[0037] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.

[0038] Example 1

[0039] like Figure 1 The diagram shown is a structural schematic of a kitchen waste treatment device provided in this application, including an outer cylinder 1 and an inner cylinder assembly disposed inside the outer cylinder 1.

[0040] The inner cylinder assembly includes an openable cover 3, an intermediate component 4, and a heat-conducting inner cylinder 2 for containing kitchen waste. The heat-conducting inner cylinder 2 can be made of a metal material with good thermal conductivity and corrosion resistance, such as stainless steel. The heat-conducting inner cylinder 2 is wrapped with a heating pad 5, which can be made of flexible heating wire to better fit the heat-conducting inner cylinder 2, thereby ensuring heat conduction performance. An insulation layer 6 can be set on the outer periphery of the heating pad 5, which can prevent heat loss and improve the working efficiency of the heating pad 5, and also prevent the heating pad 5 from scorching the external components (such as the outer cylinder 1, control circuit board 22, easily aging seals, etc.) at high temperatures, thus preventing accelerated high-temperature aging of other components.

[0041] Before composting, fermentation bacteria can be added to the food waste to regulate the microbial community and accelerate fermentation. To ensure the activity of the bacteria, the temperature and humidity of the food waste should be controlled within a reasonable range. Therefore, the device provided in this application is also equipped with a temperature and humidity sensor to collect the temperature and humidity of the food waste. The user can manually or automatically control the working mode of the heating pad 5 (including turning it on, off, and adjusting its heating power through gears) based on the collected temperature and humidity data. The controller can be connected to the circuit board 22 and embedded together in the outer cylinder 1.

[0042] The heat-conducting inner cylinder 2 can have a waste disposal opening at the top or side. The intermediate component 4 serves as a connector between the heat-conducting inner cylinder 2 and the cover component 3, and is at least partially embedded in the waste disposal opening. Alternatively, the intermediate component 4 can be made of a slightly elastic rubber material, with an interference fit to the waste disposal opening to ensure a tight seal at the connection. The cover component 3 covers the intermediate component 4, and a sealing ring can be used to seal the connection between them.

[0043] In this embodiment, the intermediate component 4 is provided with a one-way air inlet communicating with the interior of the heat-conducting inner cylinder 2. To achieve one-way air intake, a one-way air intake valve can be additionally configured for the air inlet after the air inlet is provided on the intermediate component 4. To prevent the kitchen waste from attracting mosquitoes, cockroaches, or blocking other foreign objects from entering, an air intake box 19 can be separately provided at the one-way air inlet. The air intake box 19 includes an air intake plate with multiple one-way air intake holes and a filter screen 20 provided on the air intake side of the air intake plate. The one-way air inlet provides the necessary air for composting and fermentation of the kitchen waste in the cylinder, and prevents the odorous air produced by composting and fermentation from escaping and polluting the surrounding air environment. To ensure the air pressure balance inside and outside the heat-conducting inner cylinder 2, an air outlet is also provided on the intermediate component 4. This air outlet is connected to a deodorizing mechanism to deodorize and purify the odorous air discharged from the cylinder.

[0044] The inner heat-conducting cylinder 2 is equipped with a speed-adjustable garbage shredder mechanism, and the bottom of the outer cylinder 1 is equipped with a weight sensor 7, which can sense the weight of the kitchen waste. Users can manually or automatically adjust the speed of the garbage shredder mechanism and / or adjust the heating power of the heating pad 5 based on the weight of the kitchen waste inside the cylinder. Simultaneously, users can also use the weight sensor 7 to ascertain the storage status of the kitchen waste inside the cylinder without opening the cover 3, allowing for timely emptying of the kitchen waste.

[0045] The food waste treatment device provided in this application is equipped with a circuit board 22, which includes at least a controller. The temperature and humidity sensor and the weight sensor 7 can be connected to the input terminal of the controller, and the output terminal of the controller is connected to the deodorization mechanism, the waste pulverizing mechanism, and the heating pad 5. To enhance operability and improve the intelligence level of this application, a human-machine interface, including knobs and / or buttons and / or a touchscreen, can also be configured.

[0046] Example 2

[0047] The food waste treatment device provided in this embodiment is based on the same technical concept as that in Embodiment 1, and includes all the technical features of Embodiment 1. In this embodiment, the deodorization mechanism includes an exhaust fan 8, an exhaust pipe 9, an activated carbon box 10, and an ozone generator 11.

[0048] One end of the exhaust pipe 9 is connected to the air outlet on the intermediate component 4, and the other end is connected to the exhaust port of the exhaust fan 8 via the activated carbon box 10. Multiple ozone generators 11 can be configured and placed at different positions on the exhaust pipe 9. Both the exhaust fan 8 and the activated carbon box 10 are located at the bottom of the heat-conducting inner cylinder 2, inside the outer cylinder 1. It should be understood that as a deodorizing mechanism, good airtightness should be ensured to prevent the escape of putrid and foul-smelling air.

[0049] To ensure that the putrid and foul-smelling air is completely treated and that the treated air does not pollute the surrounding air environment, the exhaust duct 9 should be long enough to extend the air treatment time. Therefore, in this embodiment, the exhaust duct 9 is configured with a reciprocating bending structure, such as... Figure 5 As shown, the exhaust duct 9 can be assembled from multiple straight pipes and bends. To reduce the space occupied inside the outer cylinder 1 and to facilitate the later cleaning, maintenance, and replacement of other related components (such as the ozone generator 11), the exhaust duct 9 can be attached to the outside of the outer cylinder 1.

[0050] See also Figure 1 The exhaust fan 8 is externally provided with an exhaust fan housing 12, and a rubber ring 13 is provided around the air inlet of the exhaust fan 8 to ensure that there is no air leakage between the exhaust fan 8 and the exhaust fan housing 12. The exhaust fan housing 8 is connected to the air outlet of the activated carbon box 10 through a conical cylinder 21. The side of the conical cylinder 21 closer to the activated carbon box 10 has a small diameter port, and the side closer to the exhaust fan 8 has a large diameter port. The design of the conical cylinder 21 helps to enhance the suction power of the exhaust fan 8.

[0051] In some embodiments, the waste shredding mechanism includes an adjustable-speed motor 14 disposed below the heat-conducting inner cylinder 2, a shredding blade assembly 15 disposed inside the heat-conducting inner cylinder 2, and a gear transmission assembly for transmitting power between the adjustable-speed motor 14 and the shredding blade assembly 15. The gear transmission assembly includes a large gear 16 driven by the shredding blade assembly 15, a small gear 17 driven by the output shaft of the adjustable-speed motor 14, and a chain 18 driving the large gear 16 and the small gear 17. The chain 18 transmission structure ensures an accurate average transmission ratio, transmits a large amount of power, and exerts a small force on the shaft and bearings, resulting in high transmission efficiency.

[0052] The shredder assembly 15 includes a horizontally arranged rotating shaft and multiple cutters staggered on the rotating shaft. The bottom of the heat-conducting inner cylinder 2 has an arc-shaped structure adapted to the cutting area of ​​the cutters. Compared to a square-bottomed heat-conducting inner cylinder 2, the arc-shaped structure of the heat-conducting inner cylinder 2 provided in this embodiment not only makes it easier to clean but also prevents food waste from accumulating in the corners of the heat-conducting inner cylinder 2. In addition, the horizontal arrangement of the rotating shaft compared to a vertical arrangement can lower the center of gravity of the entire food waste treatment device and increase the stability of the food waste treatment device during operation.

[0053] The cover 3, as an important sealing component of the heat-conducting inner cylinder 2, includes an outer cover 301, a first inner cover 302, and a second inner cover 303. Both the first inner cover 302 and the second inner cover 303 have through holes in their middle portions. The outer cover 301 is rotatably connected to the first inner cover 302 via a damping shaft 304. The second inner cover 303 is located between the first inner cover 302 and the intermediate component 4, and is sealed to both the first inner cover 302 and the intermediate component 4 via a first sealing ring 305 and a second sealing ring 306, respectively. When disposing of kitchen waste, the outer cover 301 is lifted, and the kitchen waste is poured into the heat-conducting inner cylinder 2 through the through holes. The cover automatically closes under the drive of the damping shaft 304.

[0054] The outer cylinder 1 can be integrally injection molded from rigid plastic or it can be a split structure. In this embodiment, the outer cylinder 1 includes a bottom shell 101, and a front shell 102, a rear shell 103, a left side plate 104, and a right side plate 105 respectively connected to the front, rear, left, and right sides of the bottom shell 101. Figure 6 As shown, multiple weight sensors 7 are provided, and the multiple weight sensors 7 are distributed at the bottom of the bottom shell 101.
