Description

Technical Field

[0001] This invention relates to the field of kitchen appliances technology, specifically an intelligent kitchen waste treatment device. Background Technology

[0002] With continuous technological innovation and improvements in waste disposal devices, there are increasingly more smart kitchen food waste disposers on the market. These devices aim to solve problems such as inconvenience in handling household kitchen waste, poor hygiene, and cumbersome subsequent sorting and disposal. Generally, smart kitchen waste disposal devices perform simple solid-liquid separation and packaging of kitchen waste that meets certain requirements, which improves the cleanliness and convenience of the kitchen environment to a certain extent.

[0003] However, these solutions still have the following drawbacks: First, traditional solid-liquid separation often employs gravity filtration or centrifugal drying. Gravity filtration typically uses static filter screens or bags, relying on the weight of the waste itself to allow the liquid to slowly seep out. This method is inefficient, time-consuming, and prone to clogging the filter pores for food waste with high fiber content and viscosity (such as vegetable leaves and porridge), leading to incomplete separation. While centrifugal drying technology accelerates liquid-solid separation through centrifugal force generated by high-speed rotation, its separation effect is greatly affected by the composition of the waste, the initial moisture content, and the rotation time. Short centrifugation times are insufficient to effectively remove water embedded within the solids; while excessively long centrifugation times result in high energy consumption, noise levels, and increased mechanical wear. More importantly, both gravity filtration and centrifugal drying primarily target free water on the particle surface, and their ability to remove water adsorbed within solid particles through capillary action and bound water is very limited. This results in the solid waste after separation often still having a moisture content of 60% or more, which not only easily breeds bacteria and produces odors, but also makes the garbage bags easy to break and has a low load-bearing capacity during subsequent packaging.

[0004] Secondly, in the transfer, collection, and packaging of separated solid waste, the automation and integration of existing equipment are significantly insufficient. Separated wet waste is often first discharged into a temporary collection box or trough. Once a certain amount accumulates, the user needs to manually open the device, remove the collection box, and then pour or transfer the waste into a dedicated garbage bag. This process is not only cumbersome and disrupts the continuity of processing, but more importantly, it poses serious hygiene risks. Users are forced to directly contact or be in close proximity to unsealed, potentially already decomposing wet waste, resulting in a poor user experience. Even designs that attempt to connect the separation outlet and the garbage bag using conveyor belts or chutes often suffer from poor transport, blockages, or leaks due to the high moisture content and strong adhesion of the waste, leading to low reliability. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent kitchen waste treatment device to solve the problems of limited dehydration capacity and high water content in the existing technology when separating solid and liquid kitchen waste.

[0006] The technical solution of this invention is: An intelligent kitchen waste treatment device includes a housing, a crushing mechanism, a solid-liquid separation mechanism, and a packaging and collection mechanism. The housing contains, from top to bottom, a crushing chamber, a separation chamber, and a packaging and collection chamber. The housing has a waste feeding channel communicating with the crushing chamber. The crushing mechanism is located within the crushing chamber and is used to crush the waste fed into it. The solid-liquid separation mechanism is located within the separation chamber and includes a solid-liquid separation filter, a piston, a linear motion assembly, a waste liquid collection container, and a solid waste collection tank. The solid-liquid separation filter is cylindrical and horizontally positioned, with its top communicating with the crushing mechanism via a conveying pipe. The piston is slidably connected within the solid-liquid separation filter. The linear motion assembly is located within the separation chamber and has a horizontal moving end. A horizontally moving end is connected to the piston and is used to drive the piston to move within the solid-liquid separation filter screen. A waste liquid collection container is located directly below the solid-liquid separation filter screen and is used to collect waste liquid flowing out from the filter holes. A waste solid collection tank is located below one side of the solid-liquid separation filter screen and is used to collect waste solid pushed out by the piston. A baling and collection mechanism is located within the baling and collection chamber and includes a garbage bag storage box, a bag laying assembly, and a sealing assembly. The garbage bag storage box is located below the waste solid collection tank and contains a garbage bag with an open end. The garbage bag is folded outward from the open end and stacked for storage. The bag laying assembly is used to lay out the garbage bag to receive the waste solid introduced by the waste solid collection tank. The sealing assembly is used to seal the garbage bag.

[0007] Preferably, as a further improvement of the present invention, the linear motion component is any one of an electric push rod, a lead screw linear module, or a hydraulic cylinder.

[0008] Preferably, as a further improvement of the present invention, the crushing chamber is provided with a crushing bin, the top of the crushing bin is connected to the waste feeding channel, the bottom of the crushing bin is connected to the conveying pipe, and the crushing mechanism includes two sets of crushing components arranged on both sides of the crushing bin. Each set of crushing components includes a first motor, a first shaft and a cutting blade. The first motor is mounted and fixed in the crushing chamber, the output shaft of the first motor is connected to the first shaft, the cutting blade is fixedly mounted on the first shaft, and the side wall of the crushing bin is provided with a cutting groove for the cutting blade to pass through.

[0009] Preferably, as a further improvement of the present invention, the cutting blade is shaped like a willow leaf, and the edge of the cutting blade is serrated, and the cutting blade adopts a multi-blade design.

[0010] Preferably, as a further improvement of the present invention, a centrifugal crusher is connected to the bottom of the crushing chamber for fine crushing and pre-separation of the incoming wet kitchen waste. The centrifugal crusher includes a casing, a second motor, a second shaft, crushing blades, a screen plate, and grinding cones. The screen plate is fixed inside the casing, dividing the internal space of the centrifugal crusher into upper and lower layers. The second motor is fixed at the bottom center of the screen plate. One end of the second shaft is connected to the output shaft of the second motor, and the other end of the second shaft extends above the screen plate and is connected to the crushing blades. There are multiple grinding cones, evenly distributed and fixed around the inner wall of the casing. The top of the casing of the centrifugal crusher is connected to the outlet of the crushing chamber, and the bottom of the casing of the centrifugal crusher is connected to the conveying pipe.

[0011] Preferably, as a further improvement of the present invention, the crushing blade is star-shaped, has multiple cutting edges, and the thickness of the cutting edges increases sequentially inward along the radial direction of the second axis.

[0012] Preferably, as a further improvement of the present invention, the bag-laying assembly includes turbine fans disposed on three sides of the device housing. By exhausting air through the turbine fans and balancing the air pressure, the outside air moves downward into the interior of the stacked garbage bags, and the garbage bags are pushed downward by the outside air to spread them out downward.

[0013] Preferably, as a further improvement of the present invention, the sealing assembly includes a hot-melt lever and a lever drive motor. There are two sets of hot-melt levers arranged in an X shape. One end of each hot-melt lever is connected to the output shaft of the lever drive motor. The body of the lever drive motor is fixed inside the packaging and collection chamber. A heating element is provided in the middle of each set of hot-melt levers, which can perform hot-melt sealing operation on the garbage bag.

[0014] Preferably, as a further improvement of the present invention, the packaging and collection cavity is further provided with a garbage bag transfer mechanism located below the garbage bag storage box, for automatically removing the packaged garbage bags. The garbage bag transfer mechanism includes a drawer, a sliding assembly, and a pressure detection module. The housing of the device has an opening for the drawer to extend, and the drawer is slidably connected to the opening. The sliding assembly is disposed on both sides of the drawer. The sliding assembly includes a third motor, a pulley assembly, a conveyor belt, and a sliding bracket. The third motor is mounted and fixed inside the packaging and collection cavity. One axle of the pulley assembly is connected to the output shaft of the third motor. The conveyor belt is connected between the pulley assemblies. The sliding bracket is connected between the conveyor belt and the drawer. The pressure detection module is disposed on the bottom plate of the drawer and is electrically connected to the third motor. When a garbage bag falls onto the drawer, the pressure detection module detects a pressure change and controls the third motor to rotate, thereby moving the drawer out through the sliding assembly.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. The process of first crushing and then separating by horizontal piston extrusion replaces the traditional gravity filtration or centrifugal drying process. The crushing process reduces the volume of the waste, which is more conducive to the separation of its internal moisture. Through the continuous advancement and friction extrusion of the piston in the cylindrical filter screen, not only can the free moisture on the surface of the waste be effectively discharged, but also the capillary water and some bound water adsorbed inside the solid particles can be squeezed out by mechanical pressure, so that the moisture content of the separated solid waste is greatly reduced.

[0016] 2. Through integrated design, crushing, separation, conveying, bagging, and sealing are integrated into the same device, realizing full automation from garbage input to bagging and sealing. The separated solid waste falls directly into the automatically laid-out garbage bag through the solid waste collection tank and is automatically sealed by the sealing component. Users do not need to touch the garbage, eliminating secondary pollution and odor diffusion, and greatly improving hygiene and user experience.

[0017] 3. The separated waste liquid is collected in a special collection container and can be discharged through a drain pipe to prevent the waste liquid from mixing with solid residue or contaminating the garbage bag, thus keeping the inside of the device and the garbage bag dry and clean.

[0028] The following is combined Figures 1-10 The specific embodiments of the present invention will be described in detail below. In the description of the invention, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0029] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature; in the description of the invention, unless otherwise stated, "a plurality of" means two or more.

[0030] Example 1 like Figures 1-10As shown, this embodiment of the invention provides an intelligent kitchen waste treatment device, including a device housing 1, a crushing mechanism, a solid-liquid separation mechanism, and a packaging and collection mechanism. The device housing 1 has a crushing chamber, a separation chamber, and a packaging and collection chamber arranged sequentially from top to bottom inside. The device housing 1 has a waste feeding channel communicating with the crushing chamber. The crushing mechanism is located inside the crushing chamber and is used to crush the waste fed into the crushing chamber. The solid-liquid separation mechanism is located inside the separation chamber and includes a solid-liquid separation filter 31, a piston 32, a linear motion component 33, a waste liquid collection container 34, and a waste solid collection tank 35. The solid-liquid separation filter 31 is cylindrical and horizontally arranged, with its top communicating with the crushing mechanism through a conveying pipe 311. The piston 32 is slidably connected inside the solid-liquid separation filter 31. The linear motion component 33 is located inside the separation chamber and has a horizontal moving end connected to the piston 32. The piston 32 is used to move within the solid-liquid separation filter 31. The waste liquid collection container 34 is located directly below the solid-liquid separation filter 31 and is used to collect the waste liquid flowing out of the filter holes. The solid waste collection tank 35 is located below one side of the solid-liquid separation filter 31 and has an inwardly inclined guide surface at 45° to guide the solid waste pushed out by the piston 32 into the baling and collection mechanism. The baling and collection mechanism is located inside the baling and collection chamber and includes a garbage bag storage box 41, a bag laying assembly 42, and a sealing assembly. The garbage bag storage box 41 is located below the solid waste collection tank 35 and contains a garbage bag with an open end. The garbage bag is long and cylindrical for easy sealing. The garbage bag is folded outward from the open end and stacked for storage. The bag laying assembly 42 is used to lay out the garbage bag to receive the solid waste introduced by the solid waste collection tank 35, and the sealing assembly is used to seal the garbage bag.

[0031] In this embodiment, the pulverizing mechanism can pulverize the kitchen waste entering the pulverizing chamber. The pulverized kitchen waste is easy to drain water from. The pulverized waste liquid and solid waste enter the solid-liquid separation filter 31 through the conveying pipe 311. The solid-liquid separation filter 31 first separates some waste liquid and collects it through the waste liquid collection container 34. The solid waste is driven by the linear moving component 33 and pushed by the piston 32 to verify the axial movement of the cylindrical solid-liquid separation filter 31. During the movement of the solid waste, the friction with the solid-liquid separation filter 31 can further squeeze out the water inside and collect it through the waste liquid collection container 34. Finally, the solid waste is pushed out from one side outlet of the solid-liquid separation filter 31 by the piston 32 and enters the garbage bag laid out by the bag laying component 42 under the guidance of the solid waste collection tank 35. Then, it is sealed by the sealing component, completing the automated process of solid waste separation and packaging collection of kitchen waste. The waste liquid collection container 34 can collect the separated waste liquid and prevent it from flowing into the garbage bag and affecting its function.

[0032] The waste liquid collection container 34 is box-shaped and has a drain pipe 341 on one side. The drain pipe 341 extends to the outside of the device housing 1 and is equipped with a gate valve.

[0033] As one of the several optional embodiments of the linear motion component 33, the linear motion component 33 can be any one of an electric push rod, a lead screw linear module, or a hydraulic cylinder.

[0034] In practical implementation, the linear motion component 33 is a lead screw linear module, which consists of a hollow lead screw motor, a lead screw, and a limiting guide rail. The hollow lead screw motor is mounted and fixed inside the separation chamber, and the lead screw passes through the hollow lead screw motor and is threadedly connected to it. The piston 32 is slidably connected to the limiting guide rail. The lead screw linear module converts rotational motion into linear motion, thereby driving the piston 32 to move horizontally within the solid-liquid separation filter screen 31, realizing the function of separating and pushing the shredded waste.

[0035] The crushing chamber is equipped with a crushing bin 2. The top of the crushing bin 2 is connected to the waste feeding channel, and the bottom of the crushing bin 2 is connected to the conveying pipe 311. The crushing mechanism includes two sets of crushing components arranged on both sides of the crushing bin 2. Each set of crushing components includes a first motor 21, a first shaft 22, and a cutting blade 23. The first motor 21 is mounted and fixed in the crushing chamber. The output shaft of the first motor 21 is connected to the first shaft 22. The cutting blade 23 is fixedly mounted on the first shaft 22. The side wall of the crushing bin 2 is provided with a cutting groove for the cutting blade 23 to pass through.

[0036] During crushing, the first shaft 22 is powered by the first motor 21. There are multiple sets of cutting blades 23 on each first shaft 22, which rotate and cut around the first shaft 36. The blades of the two sets of cutting blades 23 are arranged in a staggered manner, that is, the two sets of cutting blades 23 on different first shafts 22 are stacked in a staggered manner. This setting is conducive to better crushing of kitchen waste, and there is no need to perform the "cutting" operation on the kitchen waste put into the device, thus expanding the volume range of crushed kitchen waste.

[0037] Furthermore, the cutting blade 23 is shaped like a willow leaf, and its edges are serrated. The cutting blade 23 adopts a multi-blade design with 5 cutting edges. The cutting angle of the cutting blade 23 is 10°-15°, the back angle of the cutting blade 23 is 5°, and the tilt angle of the cutting blade 23 is designed to be 30°. Through the above settings, the willow leaf-shaped cutting blade 23 can reduce resistance, the serrated edges of the cutting blade 23 can better handle fibrous waste, the multi-blade design can improve crushing efficiency, and optimize the cutting angle and tilt angle, significantly enhancing cutting efficiency and material flowability. It can easily handle fibrous and tough kitchen waste, while reducing energy consumption and resistance and extending the service life of the blade.

[0038] Furthermore, a centrifugal crusher 24 is connected to the bottom of the crushing chamber 2 for fine crushing and pre-separation of the incoming wet kitchen waste. The centrifugal crusher 24 includes a casing, a second motor 241, a second shaft 242, crushing blades 243, a screen 244, and grinding cones 245. The screen 244 is mounted and fixed inside the casing, dividing the internal space of the centrifugal crusher 24 into upper and lower layers. The second motor 241 is fixed at the bottom center of the screen 244. One end of the second shaft 242 is connected to the output shaft of the second motor 241, and the other end of the second shaft 242 extends above the screen 244 and is connected to the crushing blades 243. There are multiple grinding cones 245, which are evenly distributed and fixed around the inner wall of the casing. The top of the casing of the centrifugal crusher 24 is connected to the outlet of the crushing chamber 2, and the bottom of the casing of the centrifugal crusher 24 is connected to the conveying pipe 311.

[0039] During the crushing process, driven by the second motor 241 located at the center of the centrifugal crusher 24, the grinding cone 245 and the crushing blade 243 can further crush and refine the kitchen waste that has been initially crushed by the crushing mechanism under the combined action of centrifugal force and shear force. The waste is circulated and impacted between the crushing blade 243 and the grinding cone 245, thereby achieving thorough crushing. Furthermore, the crushing blade 243 can be used to crush tough waste that is difficult to crush by its own centrifugal force, increasing the types of kitchen waste that can be crushed.

[0040] The crushing blade 243 is star-shaped and has multiple cutting edges, with the thickness of the cutting edges increasing inward along the radial direction of the second axis 242.

[0041] The screen plate 244 has multiple through holes, which are arranged in a distribution structure with gradually changing diameters from the inside to the outside: the diameter of the holes in the central area is smaller, which is suitable for restricting large particles from passing through directly; the diameter of the holes in the outer area is relatively larger, which is used to improve the effective discharge rate after crushing.

[0042] To prevent long-term slag accumulation in the crushing chamber and improve cleaning ability, four cleaning nozzles 25 are evenly distributed and installed around the crushing blades 243 in the centrifugal crusher 24. These cleaning nozzles 25 can spray high-pressure water flow during working intervals or after the operation to automatically flush the crushing chamber, effectively preventing the accumulation of food residue and the generation of odors.

[0043] Specifically, as an optional embodiment of the bag-laying assembly 42, the bag-laying assembly 42 in this embodiment includes turbine fans disposed on three sides of the device housing 1. By exhausting air through the turbine fans and balancing the air pressure, the outside air moves downward into the interior of the stacked garbage bags, and the garbage bags are pushed downward by the outside air to spread them out downward.

[0044] During the unfolding process, the air in the lower part of the food waste disposer is expelled to the outside by the turbine fan, and the air inside the lower part of the disposer decreases. In order to maintain the air pressure balance inside the disposer, air will move downwards from above the garbage bag storage box 41 through the garbage bag, and the garbage bag will be pushed downwards by the air to quickly unfold. Meanwhile, to detect whether the garbage bag has been properly laid, a bag-laying detection module is included. This module is an infrared sensor consisting of a generator and a receiver, placed on the bottom inner walls of the lower part of the device housing 1. If the garbage bag is properly laid (it will be black), it will block the infrared receiver. A signal change will then occur, indicating that the garbage bag has been laid. Because it has three turbine fans (front and sides), it can achieve omnidirectional bag laying with sufficient force.

[0045] The device housing 1 has an opening on its side wall for taking out and putting in the garbage bag storage box 41, which allows for easy replacement of the garbage bag storage box 41.

[0046] Specifically, as an optional implementation of the sealing assembly, the sealing assembly in this embodiment includes a hot-melt lever 43 and a lever drive motor 44. There are two sets of hot-melt levers 43, which are arranged in an X shape. One end of each hot-melt lever 43 is connected to the output shaft of the lever drive motor 44. The body of the lever drive motor 44 is mounted and fixed inside the packaging and collection chamber. Each set of hot-melt levers 44 is provided with a heating element in the middle, which can perform hot-melt sealing operation on the garbage bag.

[0047] The hot-melt process is as follows: At the start of the packaging operation, the first set of hot-melt levers 43, driven by the corresponding lever drive motors 44, rotates around the motor shaft and converges in a "scissor-like" motion towards the center, clamping and pressing the garbage bag so that it is compressed into a linear area at that position. Subsequently, the second set of hot-melt levers 43 moves from opposite ends towards the center in the same manner, also in a "scissor-like" motion, further sealing the garbage bag from a "linear" state to a "point" state, ultimately forming a completely sealed weld point.

[0048] The two sets of heat-sealing levers 43 are not on the same horizontal plane, but are arranged in an "X" shape, which can sequentially achieve the transition from a "linear" seal to a "point" break, improving the heat seal strength and airtightness. The heating element on the heat-sealing lever continuously heats up during this process. After the garbage bag is clamped and positioned, it is melted and broken at the contact point by high-temperature heating, realizing the integrated operation of heat sealing and breaking.

[0049] The beneficial effects of setting up two sets of hot-melt levers 43 in this device are as follows: the first set achieves the initial sealing of the garbage bag, forming a "line"-shaped isolation strip to prevent leakage of contents; the second set further seals into "dots", completely separating the sealed bag body from the remaining unused garbage bags in the garbage bag storage box 41, thereby ensuring that the packaged garbage bags are separated independently.

[0050] Furthermore, a garbage bag transfer mechanism is also provided inside the packaging and collection chamber, located below the garbage bag storage box 41, for automatically removing the packaged garbage bags. The garbage bag transfer mechanism includes a drawer 51, a sliding assembly, and a pressure detection module. An opening is provided on the device housing 1 to allow the drawer 51 to extend. The drawer 51 is slidably connected to the opening. The sliding assembly is located on both sides of the drawer 51. The sliding assembly includes a third motor 52, a pulley assembly 53, a conveyor belt 54, and a sliding bracket 55. The third motor 52 is mounted and fixed inside the packaging and collection chamber. One axle of the pulley assembly 53 is connected to the output shaft of the third motor 52. The conveyor belt 54 is connected between the pulley assemblies 53. The sliding bracket 55 is connected between the conveyor belt 54 and the drawer 51. The pressure detection module is located on the bottom plate of the drawer 51 and is electrically connected to the third motor 52. When a garbage bag falls onto the drawer 51, the pressure detection module detects the pressure change and controls the third motor 52 to rotate, causing the drawer 51 to move out through the sliding assembly.

[0051] After the garbage bag is packed, it is supported by a movable drawer 51. When the garbage bag falls onto the drawer 51, the pressure detection module detects the pressure change and controls the third motor 52 to rotate, which moves the drawer 51 out through the sliding component. The packed garbage bag is automatically removed from the device without the need to open the garbage lid 67 to take out the garbage bag, thus improving the performance of the invention.

[0052] In another embodiment of the present invention, the upper part of the device housing 1 is provided with a speaker 61, a microphone 62, a fragrance nozzle, a fragrance module 65, an infrared distance sensor 66, and a trash can lid 67. A mosquito-killing grid 71 is provided on the surface of the trash can lid 67, and a mosquito-killing lamp 72 is located below the trash can lid 67. The infrared distance sensor 66 has a sensing distance of approximately 20 cm. When an object enters the range of the infrared distance sensor 66, the infrared distance sensor 66 activates, and the infrared sensor opens the trash can lid 67. Because the mosquito-killing grid 71 is provided on the surface of the trash can lid 67 on the upper part of the device housing, and the mosquito-killing lamp 72 is located below the trash can lid 67, when the control system is turned on and powered on, the mosquito-killing lamp 72 illuminates, attracting mosquitoes to capture the light. The mosquitoes must pass through the mosquito-killing grid 71 embedded in the trash can lid 67, resulting in an electric shock that kills them. The upper part of the device housing is provided with a fragrance nozzle and a fragrance module 65. The fragrance module 65 can generate ultrasonic vibrations, using these vibrations to convert liquid perfume into water vapor or small liquid particles, which are then released into the air. When activated, the ultrasonic generator produces high-frequency vibration signals, which are transmitted to the vibrating plate. Upon receiving these signals, the plate vibrates rapidly, generating ultrasonic waves. These vibrations cause a very thin film to form on the surface of the liquid perfume, which gradually forms tiny droplets that are released through the fragrance nozzle 64.

[0053] Furthermore, to facilitate intelligent control, a control system is also provided. This control system is divided into touchscreen control and voice control. The touchscreen 8 in the touchscreen control is located on the front of the upper part of the device housing. The touchscreen 8 in the control system has functions such as displaying kitchen humidity, temperature, power consumption, and time, and allows for touchscreen operation of all functions, such as packing. The voice control includes a speaker 61, a microphone 62, and an STM32F103C8T6 chip and an electromagnetic relay inside the voice control board, all located on the top surface of the upper part of the device housing. When the STM32F103C8T6 chip recognizes the corresponding voice command, it outputs a high-level signal to the electromagnetic relay, activating the corresponding electromagnetic relay channel. Upon receiving the signal from the chip, the electromagnetic relay closes its normally open contacts or opens its normally closed contacts according to the voice command, thus connecting or disconnecting the main circuit corresponding to the voice command.

[0054] In another embodiment of the present invention, a cleaning device is provided on the inner top of the device housing 1, comprising a water tank, water pipes, and a water pump 11 located on the inner top of the device housing 1. Four cleaning nozzles are provided on the four square faces above the waste inlet channel and are connected to the water pipes. The control system activates the cleaning device to clean the interior of the upper part of the device housing. The water pump 11, located on the upper right side of the interior of the upper part of the device housing, operates, drawing water from the water tank inside the upper part of the device housing into the water pipes, and then spraying it out from the cleaning nozzles. Because there are four cleaning nozzles, each located on one of the four square faces above the waste inlet channel, the interior of the upper part of the device housing can be cleaned from all directions, ensuring the cleanliness of the device housing.

[0055] In another embodiment of the present invention, in order to achieve the purpose of cockroach extermination, a cockroach extermination mechanism is also provided. The cockroach extermination mechanism achieves the purpose of cockroach extermination through the combined action of a fan 91 and a liquid medicine plate 92. The liquid medicine plate 92 is composed of a high molecular material with adsorption resin, which has a strong water absorption function and excellent water retention performance. The fan 91 is located on the upper part of the liquid medicine plate 92 and blows air towards the ground, blowing the cockroach medicine adsorbed in the liquid medicine plate 92 onto the ground, forming a thin cockroach-killing area on the ground, thereby achieving the purpose of cockroach extermination.

[0056] The above-disclosed embodiments are merely preferred embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
