Description

Technical Field

[0001] This invention relates to the technical field of kitchen appliances, specifically to a sink drainage device and sink equipment. Background Technology

[0002] In daily life, such as in the kitchen, sinks are frequently used, and a filter screen is usually installed at the drain. The filter holes on the screen are easily clogged by food waste, causing problems such as poor drainage and foul odors.

[0003] In existing technologies, we usually need to clean the filter screen frequently by hand, which is very troublesome, disgusting, and a headache. To address this, some people use food waste processing equipment to process the food waste accumulated inside the filter screen, breaking it down so that the broken-down food waste can be discharged through the filter holes.

[0004] When food waste needs to be processed from the filter, the food waste disposer is installed on the sink. After processing, the disposer is removed, and the sink returns to its normal function. In actual use, the frequent installation and removal of the food waste disposer is cumbersome and requires a reliable place to store the removed device, resulting in a poor user experience. Summary of the Invention

[0005] To at least partially address the problems existing in the prior art, according to one aspect of the present invention, a sink drainage device is provided. The sink drainage device includes: a filtering mechanism having an upward-opening collection trough, the lower part of which has a plurality of filter holes; and a food waste treatment mechanism including a drive assembly and a blade, the blade being connected to the drive assembly and rotatable under the action of the drive assembly. The food waste treatment mechanism has a sealed water state and a draining water state. When the food waste treatment mechanism is in the draining water state, the opening of the collection trough is open; and when the food waste treatment mechanism is in the sealed water state, the food waste treatment mechanism seals the opening of the collection trough and the blade is located inside the collection trough.

[0006] The sink drainage device provided in this application, by providing a food waste processing mechanism, can break up food waste in the collection sink, preventing its accumulation and improving the user experience. Furthermore, the food waste processing mechanism has both a drainage state and a water-sealing state, allowing it to process food waste in the collection sink when in either state or when sealed. When food waste needs to be processed, the mechanism can be positioned accordingly; when the sink needs to drain, it can be in the drainage state; and when the sink needs to hold water, it can be in the water-sealing state. Therefore, this sink drainage device, once installed at the sink's drain outlet, does not affect the sink's normal drainage and water-holding functions, and does not need to be removed from the sink, providing great convenience to the user.

[0007] For example, the food waste treatment device also includes a sealing cover, to which a drive assembly is connected. The sealing cover can open and close the collection tank to allow the food waste treatment device to have both a sealed and a drained state. The sealing cover simplifies the structure of the food waste treatment device, making it easier to manufacture and implement.

[0008] For example, the sealing cap is detachably connected to the filtering mechanism. The food waste treatment mechanism further includes: a support block movably disposed on the drive assembly and / or the sealing cap between a first station and a second station; and an elastic element connected between the support block and the drive assembly or between the support block and the sealing cap. The elastic element applies an elastic force to the support block toward the second station. When the sealing cap is connected to the filtering mechanism, it seals the collection tank, and the support block is in the first station. When the sealing cap is disconnected from the filtering mechanism, it opens the collection tank, and the support block is in the second station. The support block and elastic element facilitate switching between a sealed state and a draining state for the food waste treatment mechanism.

[0009] For example, the support block rests on the edge of the collection tank opening. When the support block is in the second position, its position on the drive assembly is lower than its position on the drive assembly when it is in the first position, and the direction of the elastic force is vertical. With this configuration, when the support block moves from the first position to the second position, the vertical movement can be powered by the elastic element, and the user only needs to rotate the food waste processing mechanism around the axis of the drive assembly.

[0010] For example, the drive assembly includes a drive housing connected to the sealing cover and a motor disposed within the drive housing. The cutter head is located outside the drive housing and connected to the rotating shaft of the motor. An opening is provided on the side wall of the drive housing. The support block includes a connecting part and a supporting part. The connecting part is located inside the drive housing, and the supporting part extends out of the drive housing through the opening. An elastic element is connected between the connecting part and the drive housing within the drive housing. This design enhances the overall integrity of the drive assembly and makes its internal structure more compact, thereby improving the space utilization of the overall device.

[0011] For example, the drive assembly has an insertion portion that inserts into the collection groove when the sealing cap closes it. The insertion portion rests on the opening edge of the collection groove when the sealing cap opens it. The sealing cap closing the collection groove rotates by a predetermined angle relative to the sealing cap in the open collection groove about the axis of the drive assembly. The insertion portion simplifies the overall device structure and makes it easier to implement.

[0012] For example, the sidewall of the insertion part is provided with a support protrusion that protrudes radially outward from the drive assembly, and the opening edge of the collection tank is provided with a first groove that is recessed downward and communicates with the collection tank. When the sealing cap closes the collection tank, the support protrusion is inserted into the first groove and when the sealing cap opens the collection tank, it is supported on the opening edge of the collection tank. When the sealing cap closes the opening of the collection tank, the support protrusion can be inserted into the corresponding first groove, thereby making the position of the food waste processing mechanism in the collection tank more stable and improving the working efficiency of the food waste processing mechanism.

[0013] For example, a second recessed groove is provided on the edge of the opening of the collection tank and communicates with the collection tank. The depth of the second groove is less than the depth of the first groove. The support protrusion is supported on the bottom surface of the second groove when the sealing cover is opened. The second groove can accommodate the support protrusion when the sealing cover is opened, making the sealing cover more stable when the collection tank is opened, and also improving the stability of the food waste treatment device when it is in the drainage state.

[0014] For example, both the first and second grooves are multiple and are alternately and spaced apart along the circumferential direction of the drive component. Such a water tank drainage device is simpler to operate and provides a better user experience.

[0015] For example, the filtration mechanism includes an upper mounting ring and a filter basket. The filter basket is inserted into and supported on the upper mounting ring. Multiple filter holes are provided on the filter basket. The upper mounting ring and the filter basket together form a collection tank. When the sealing cap closes the collection tank, the food waste treatment mechanism is screwed onto the upper mounting ring, and the filter basket can rotate within the upper mounting ring. The filter basket and the upper mounting ring separate the collection tank into two components. This design makes production more convenient, and it facilitates the disassembly, replacement, or maintenance of the collection tank when cleaning is required. The upper mounting ring also allows the collection tank to be adapted to a wider range of needs for external connection.

[0016] For example, one of the upper mounting ring and the filter basket is provided with a first limiting groove, and the other of the upper mounting ring and the filter basket is provided with a first limiting protrusion. Along the circumferential direction of the drive assembly, the size of the first limiting groove is larger than the size of the first limiting protrusion. When the drive assembly is screwed onto the upper mounting ring, the filter basket rotates together with the drive assembly, and the first limiting protrusion rotates within the first limiting groove. This design makes the disassembly of the filter basket relatively simpler, facilitating user maintenance or cleaning of the food waste processing mechanism.

[0017] For example, the food waste disposal mechanism further includes: a water overflow cover having a drain hole, the water overflow cover covering or embedded in the collection tank, and a drive assembly connected to the underside of the water overflow cover; and a first sealing cover, which can be opened and closed to cover the water overflow cover, so that the food waste disposal mechanism has a sealed state and a drain state. The arrangement of the water overflow cover and the first sealing cover makes it easier to switch between the sealed state and the drain state of the food waste disposal mechanism, and the overall structure of the device is also simpler. The first sealing cover can replace the plug in the existing sink, so it does not increase the number of detachable parts.

[0018] For example, a drive component positioning part is provided on the side wall and / or bottom wall of the collection tank, which positions the lower part of the drive component along the radial direction of the drive component; and / or the drive component positioning part supports the lower part of the drive component. The positioning of the lower part of the drive component by the drive component positioning part can make the drive component more stable during operation, thereby improving the cutting effect of the cutter head and also improving the stability of the overall device.

[0019] For example, the food waste treatment device also includes a sensor and a controller. The sensor detects the water flow rate in the collection tank, and the controller is electrically connected to the sensor and the drive assembly. The controller controls the drive assembly based on the water flow rate to control the rotation of the blades. Specifically, when the sensor detects a large water flow rate in the sink drain, the sensor sends a signal to the controller, which then controls the drive assembly to turn on. When the sensor detects a small water flow rate or no water flow in the sink drain, the sensor sends a signal to the controller, which then controls the drive assembly to turn off. The sensor and controller setup improves the overall automation level of the device, simplifies user operation, and provides a better user experience.

[0020] For example, a guide surface is provided on the side wall of the collection tank, and the guide surface rises spirally and / or in a stepped manner along the side wall of the collection tank, with the bottom drain end of the guide surface aligned with the sensor. The arrangement of the guide surface makes the sensor more effective in detecting water flow.

[0021] For example, the outer wall of the drive component is spaced apart from the inner wall of the collection tank to form an annular channel, and the guide surface is disposed within the annular channel. The annular channel allows water to immediately converge on the guide surface within the annular channel after entering the collection tank. This makes the water flowing out from the bottom drain end of the guide surface more accurately reflect the water flow rate inside the tank's drainage device, thus further improving the sensor's ability to detect water flow.

[0022] For example, the guide surface includes a first guide surface and a second guide surface. Along the circumferential direction of the drive component, the top water-facing end of the first guide surface is adjacent to the bottom drainage end of the second guide surface and has a first gap between them, and the bottom drainage end of the first guide surface is adjacent to the top water-facing end of the second guide surface and has a second gap between them. This can shorten the path that the water flows on the guide surface, reduce the water flow loss when the water flows on the guide surface, and further improve the effect of the sensor in detecting water flow.

[0023] For example, the sensor is positioned at the first and / or second interval. This design facilitates the removal of the sensor from the food waste handling unit.

[0024] For example, the sensor is mounted on the drive assembly. The sensor and drive assembly can be powered by a power source within the food waste disposal unit, which simplifies the circuitry of the sink drain device, making the overall device structure simpler and easier to implement.

[0025] For example, the food waste disposal unit is detachably connected to the filtration unit, and the sink drain device includes a second sealing cap that seals the opening of the collection tank when the food waste disposal unit is detached. The design of the second sealing cap conforms to user habits; when the food waste disposal unit is detached, the method of using the second sealing cap is the same as that of using the sealing cap in an existing sink. This design is user-friendly and provides a good user experience.

[0026] For example, the filtration mechanism further includes: a filter basket with multiple filter holes disposed on it; and a drain housing with a drain pipe interface at its lower part, into which the filter basket is inserted. Connecting the filtration mechanism to the outside via the drain housing is more convenient, and the drain housing also protects the internal structure of the filtration mechanism, making the overall device more stable.

[0027] For example, the filtration mechanism further includes an upper mounting ring surrounding the filter basket, which is connected to the drain housing. An annular mounting groove is formed between the upper mounting ring and the edge of the drain housing. The upper mounting ring and the filter basket together form a collection trough, and the food waste treatment mechanism is connected to the upper mounting ring. A sealing ring may be provided in the mounting groove to improve the overall sealing performance of the device.

[0028] For example, one of the upper mounting ring and the filter basket is provided with a limiting groove, and the other of the upper mounting ring and the filter basket is provided with a limiting protrusion. In this way, the upper mounting ring can limit the rotation of the filter basket, making the overall device more stable.

[0029] According to another aspect of the present invention, a sink device is also provided. The sink device includes a sink with a drain outlet and any of the sink drainage devices described above, the sink drainage device being connected to the drain outlet. In use, such a sink device allows the sink drainage device to handle food waste, preventing its accumulation; moreover, the sink device's drainage and water storage functions are unaffected by the food waste handling function.

[0030] A series of simplified concepts are introduced in the description of the invention, which will be further explained in detail in the detailed description section. This description is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

Detailed Implementation

[0055] In the following description, numerous details are provided to enable a thorough understanding of the invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the invention, and that the invention can be practiced without one or more of these details. Furthermore, to avoid obscuring the invention, some technical features well-known in the art have not been described in detail.

[0056] According to one aspect of the present invention, a sink drainage device is provided. This sink drainage device can handle kitchen waste in the collection sink, preventing its accumulation. Furthermore, the kitchen waste handling mechanism of the sink drainage device has a sealed water state and a draining water state. When the sink where the sink drainage device is installed needs to hold water normally or when waste needs to be processed in the collection sink, the kitchen waste handling mechanism can be placed in the sealed water state; when the kitchen waste handling mechanism is in the draining water state, the sink where the sink drainage device is installed can drain normally. Moreover, when kitchen waste is not needed, the kitchen waste handling mechanism does not need to be disassembled, and the normal use of the sink is not affected, making it very convenient for the user.

[0057] According to another aspect of the present invention, a sink device is provided, which may include a sink with a drain outlet and any of the sink drainage devices described below, the sink drainage device being connectable to the sink drain outlet. In use, such a sink device allows the sink drainage device to handle food waste, preventing its accumulation, and the sink device's inherent drainage and water storage functions are unaffected by the food waste handling function.

[0058] like Figure 1 As shown, the sink drainage device 10 may include a filtration mechanism 100 and a food waste treatment mechanism 200.

[0059] like Figure 1-2 As shown, the filter mechanism 100 can be equipped with an upward-opening collection trough 110, and the lower part of the collection trough 110 can be provided with multiple filter holes. The collection trough 110 can be a cylindrical structure with a circular cross-section or a box-shaped structure with a square cross-section. The specific shape and size of the collection trough 110 can be designed to suit actual needs and are not specifically limited here. The multiple filter holes enable the collection trough 110 to have a drainage function. Some larger kitchen waste cannot pass through the filter holes and will be collected in the collection trough 110.

[0060] like Figure 2-3As shown, the food waste processing mechanism 200 may include a drive assembly 210 and a blade 220. The blade 220 can be connected to the drive assembly 210 and can rotate under the action of the drive assembly 210. It is understood that the drive assembly 210 has good sealing properties, preventing external water from entering its interior. The blade 220 can rotate and cut the food waste accumulated in the collection tank 110 under the action of the drive assembly 210. After being broken up by the blade 220, the food waste can be discharged through the filter holes of the collection tank 110. The drive assembly 210 may include a switch. When it is necessary to break up the food waste in the collection tank 110, the user can control the drive assembly 210 to open via the switch, thereby driving the blade 220 to rotate and cut the food waste. In some embodiments, the drive assembly 210 may also be controlled by a sensor and a controller, which will be described in detail later.

[0061] The food waste processing unit 200 can have both a water-sealed state and a drainage state. When the food waste processing unit 200 is in the drainage state, the opening of the collection tank 110 can be open, allowing food waste and water to enter. Conversely, when the food waste processing unit 200 is in the water-sealed state, it can block the opening of the collection tank 110, preventing food waste and water from entering. When the food waste processing unit 200 is in the water-sealed state, the blade 220 can be located inside the collection tank 110. The user can control the blade 220 to rotate and cut the food waste via the drive component 210. After being broken down, the food waste can be discharged through the filter holes of the collection tank 110.

[0062] In some embodiments, the food waste treatment device 200 may have a sealing cap that matches the opening of the collection tank 110. Through the sealing cap, the food waste treatment device 200 can seal the opening of the collection tank 110, thereby achieving a water-sealed state. Releasing the sealing cap from the opening of the collection tank 110 switches the food waste treatment device 200 from a water-sealed state to a drainage state. The food waste treatment device 200 can freely switch between the water-sealed and drainage states. The water-sealed and drainage states of the food waste treatment device 200, and how to switch between them, will be described in detail below with reference to specific embodiments.

[0063] It is worth noting that when the food waste processing unit 200 is in the draining state, the blade 220 can also be located within the collection tank 110. For example... Figure 8 In the embodiment shown, when the food waste treatment mechanism 200 is in the draining state, the blade 220 is located in the collection tank 110. The blade 220 can cut the food waste in the collection tank 110 under the action of the drive component 210. This will be described in detail below with reference to specific embodiments.

[0064] Such a sink drainage device 10 is installed after the sink drain 21. When there is no food waste or only a small amount of food waste in the collection tank 110, the user can put the food waste processing mechanism 200 in the drainage state. At this time, water can flow through the sink drain 21, and food waste can also enter the collection tank 110. When some food waste accumulates in the collection tank 110, the user can use the food waste processing mechanism 200 to break up the food waste, so that the broken-up food waste can be discharged from the filter holes of the collection tank 110. This can reduce the accumulation of food waste in the collection tank 110. When the user needs to fill the sink with water, the food waste processing mechanism 200 can be put into the water-sealed state. At this time, no water flows through the sink drain 21, and no food waste enters the collection tank 110. The user can then fill the sink with water normally.

[0065] The sink drain device 10 provided in this application, by providing a food waste processing mechanism 200, can break up food waste in the collection tank 110, making it less prone to accumulation and improving the user experience. Furthermore, the food waste processing mechanism 200 has both a draining state and a water-sealing state. When the food waste processing mechanism 200 is in both draining and water-sealing states, or only in the water-sealing state, it can process the food waste in the collection tank 110. When food waste needs to be processed, the food waste processing mechanism 200 can be in the corresponding state; when the sink needs to drain, the food waste processing mechanism 200 can be in the draining state; when the sink needs to hold water, the food waste processing mechanism 200 can be in the water-sealing state. Therefore, this sink drain device 10, when installed after the sink drain outlet 21, does not affect the normal drainage and water holding functions of the sink, and does not need to be removed from the sink, providing great convenience to the user.

[0066] For example, such as Figure 2-3 and Figures 4a-4bAs shown, the food waste treatment mechanism 200 may further include a sealing cover 230, and the drive assembly 210 may be connected to the sealing cover 230. The sealing cover 230 can open and close the collection tank 110, allowing the food waste treatment mechanism 200 to have both a water-sealed state and a drainage state. The sealing cover 230 may be connected to the housing of the drive assembly 210 in various forms, such as integral molding, welding, splicing, or threaded connection. Of course, the sealing cover 230 may also be detachably connected to the housing of the drive assembly 210, for example, by a threaded connection. The sealing cover 230 may have a cross-sectional shape and size that matches the opening of the collection tank 110. The food waste treatment mechanism 200 can seal the opening of the collection tank 110 by the sealing cover 230, at which point the food waste treatment mechanism 200 is in a water-sealed state. When the sealing cover 230 opens the opening of the collection tank 110, the food waste treatment mechanism 200 is in a drainage state. The sealing cover 230 can open the collection tank 110 in several ways. For example, the sealing cover 230 can be moved upwards and spaced apart from the edge of the opening of the collection tank 110; or the sealing cover 230 can be detachably connected to the drive assembly 210, etc. In this case, the sealing cover 230 can optionally replace the existing plug in the sink, which will be described in detail later. The design of the sealing cover 230 makes the structure of the food waste treatment mechanism 200 simpler, easier to manufacture, and easier to implement.

[0067] exist Figure 2-3 and Figures 4a-4b In the illustrated embodiment, the sealing cap 230 protrudes upwards, and at least a portion of the drive assembly 210 is inserted into the protrusion. This is suitable when the height of the drain outlet 21 of the sink itself is limited, in which case the collection tank 110 may be relatively small or the drive assembly 210 and the cutter head 220 may be relatively large, and the collection tank 110 cannot fully accommodate the drive assembly 210 and the cutter head 220. In the embodiments described later, such as Figure 7-9 In the illustrated embodiment, the collection tank 110 is sufficiently large or the drive assembly 210 and the blade 220 are sufficiently small, and the sealing cap 230 can be configured to be substantially flush with the bottom surface of the tank, thus not occupying space within the tank. Those skilled in the art can choose the shape and size of the sealing cap 230 as needed.

[0068] For example, such as Figure 2As shown, the sealing cap 230 has an upward bulge, into which the top of the drive assembly 210 can be inserted. When the sealing cap 230 covers the collection tank 110, the drive assembly 210 may have an insertion portion (i.e., a lower portion) 214 that inserts into the collection tank 110. When the sealing cap 230 opens the collection tank 110, the insertion portion 214 can be supported on the edge of the opening of the collection tank 110. The insertion portion 214 can be designed in various shapes and sizes according to actual needs; for example, the insertion portion 214 may have a shape and size adapted to the opening of the collection tank 110. When the sealing cap 230 covers the collection tank 110, the insertion portion 214 is inside the collection tank 110, and the food waste processing mechanism 200 can be supported on the filter mechanism 100 by the drive assembly 210 and / or the sealing cap 230. When the sealing cap 230 is required to support the food waste processing mechanism 200, the size of the sealing cap 230 may be larger than the size of the opening of the collection tank 110. When the sealing cover 230 is not needed to support the food waste handling mechanism 200, the size of the sealing cover 230 can be exactly equal to the size of the opening of the collection tank 110. When the sealing cover 230 opens the collection tank 110, the insertion part 214 can be supported on the edge of the opening of the collection tank 110. At this time, there can be a gap between the other parts of the drive assembly 210 and the opening of the collection tank 110, so that water or food waste can enter the collection tank 110 through this gap.

[0069] The sealing cap 230 of the collection groove 110 can rotate around the axis PP of the drive assembly 210 by a predetermined angle relative to the sealing cap 230 when the collection groove 110 is open. In an embodiment not shown, the opening of the collection groove 110 can be an equilateral triangle, and the insertion part 214 is a corresponding equilateral triangle protrusion on the bottom of the drive assembly 210. Thus, when the insertion part 214 is inserted into the opening of the collection groove 110, the sealing cap 230 can seal the collection groove 110. When the drive assembly 210 is pulled out of the collection groove 110 and then rotated around the axis PP of the drive assembly 210 by a predetermined angle, the insertion part 214 can no longer be directly inserted into the opening of the collection groove 110; instead, the insertion part 214 can be supported on the edge of the opening of the collection groove 110, meaning that the sealing cap 230 opens the opening of the collection groove 110. The predetermined angle referred to here means any angle at which the drive assembly 210 can no longer be directly inserted into the collection groove 110 after being pulled out of the collection groove 110 and rotated around the axis PP of the drive assembly 210. For example, the openings of the insertion portion 214 and the collection slot 110 form corresponding equilateral triangles, and the predetermined angle can be any angle other than 120°, 240° and 360°.

[0070] The insertion portion 214 can also take various other forms, which will be described in detail later with reference to specific embodiments. The design of the insertion portion 214 makes the overall device structure simpler and easier to implement.

[0071] For example, such as Figure 4a and Figure 4b As shown, the sidewall of the insertion portion 214 may be provided with support protrusions 2140 that protrude radially outward from the drive assembly 210. The support protrusions 2140 shown in the figure are three evenly distributed along the circumference of the insertion portion 214. In other embodiments not shown, any number of support protrusions 2140 may be evenly distributed along the circumference of the insertion portion 214. Of course, the multiple support protrusions 2140 may also be unevenly distributed along the circumference of the insertion portion 214.

[0072] like Figure 5a and 5b As shown, a first groove 111 that is recessed downward and communicates with the collection groove 110 can be provided on the opening edge of the collection groove 110. The support protrusion 2140 can be inserted into the first groove 111 when the sealing cover 230 covers the collection groove 110, and can be supported on the opening edge of the collection groove 110 when the sealing cover 230 opens the collection groove 110.

[0073] The support protrusion 2140 and the first groove 111 can have various suitable shapes and sizes, but the shapes and sizes of the support protrusion 2140 and the first groove 111 should correspond, and the support protrusion 2140 should be able to be inserted into the first groove 111. The number of support protrusions 2140 should not exceed the number of first grooves 111. For example, three support protrusions 2140 can be evenly distributed along the circumference of the insertion portion 214, and three first grooves 111 can be evenly arranged along the opening edge of the collecting groove 110. In this case, the predetermined angle is any angle other than 120°, 240°, and 360°. Preferably, the number of support protrusions 2140 and the number of first grooves 111 can be the same.

[0074] When the sealing cap 230 seals the collection groove 110, the insertion portion 214 is inserted into the opening of the collection groove 110, and at this time, the support protrusion 2140 is inserted into the corresponding first groove 111. When the drive assembly 210 is pulled out of the collection groove 110, the support protrusion 2140 is pulled out of the first groove 111. Then, the drive assembly 210 is rotated around its axis PP by a predetermined angle. At this time, the support protrusion 2140 is misaligned with the first groove 111, and the insertion portion 214 can no longer be directly inserted into the opening of the collection groove 110. The support protrusion 2140 can support itself on the edge of the opening of the collection groove 110, meaning that the sealing cap 230 opens the opening of the collection groove 110. It can be understood that when it is said that the support protrusion 2140 is inserted into the first groove 111, it means that all support protrusions 2140 are inserted into the first groove 111 respectively.

[0075] The support protrusion 2140 and the first groove 111 allow the sealing cover 230 to have two states: open and closed, with the collection groove 110 open. When the sealing cover 230 opens the collection groove 110, it is supported by the support protrusion 2140 on the edge of the opening, thus keeping the sealing cover 230 vertically spaced from the edge of the opening. When the sealing cover 230 closes the opening of the collection groove 110, the support protrusion 2140 can be inserted into the corresponding first groove 111, thereby making the position of the food waste processing mechanism 200 within the collection groove 110 more stable and improving the working efficiency of the food waste processing mechanism 200.

[0076] Furthermore, such as Figure 5a and Figure 5b As shown, a second recessed groove 112, communicating with the collection groove 110, can also be provided on the opening edge of the collection groove 110. The depth of the second groove 112 can be less than the depth of the first groove 111. The support protrusion 2140 can be supported on the bottom surface of the second groove 112 when the sealing cover 230 opens the collection groove 110. The second groove 112 is similar to the first groove 111 and will not be described in detail here. It is worth noting that the depth of the second groove 112 is less than the depth of the first groove 111. This means that when the support protrusion 2140 is inserted into the first groove 111, the sealing cover 230 seals the collection groove 110. However, when the support protrusion 2140 is inserted into the second groove 112, the height of the sealing cover 230 will be higher than the opening edge of the collection groove 110, and there will be a gap between the sealing cover 230 and the opening edge of the collection groove 110. At this time, it is equivalent to the sealing cover 230 opening the opening of the collection groove 110. The second groove 112 can accommodate the support protrusion 2140 when the sealing cover 230 opens the collection tank 110, making the sealing cover 230 more stable when opening the collection tank 110, and also improving the stability of the food waste processing mechanism 200 when it is in the drainage state.

[0077] For example, both the first groove 111 and the second groove 112 can be multiple and can be alternately and spaced apart along the circumferential direction of the drive assembly 210. Figure 2In the illustrated embodiment, three first grooves 111 and three second grooves 112 are evenly arranged circumferentially along the opening of the collection groove 110. Correspondingly, three support protrusions 2140 are evenly arranged circumferentially along the insertion portion 214. When the insertion portion 214 is inserted into the opening of the collection groove 110, the three support protrusions 2140 are respectively inserted into the three first grooves 111, and the sealing cap 230 can seal the collection groove 110. By pulling the drive assembly 210 out of the collection groove 110 and then rotating it around the axis PP of the drive assembly 210, the three support protrusions 2140 can be simultaneously inserted into the three second grooves 112. The depth of the second groove 112 is less than the depth of the first groove 111. At this time, there will be a gap between the sealing cap 230 and the opening of the collection groove 110, meaning that the sealing cap 230 opens the opening of the collection groove 110. The above illustrated embodiment is for reference only; the number of first grooves 111 and second grooves 112 can be designed according to actual needs. The first groove 111 and the second groove 112 are alternately and spaced apart along the circumferential direction of the drive assembly 210. The drive assembly 210 can rotate a small angle around its axis PP, which allows the sealing cover 230 to switch between opening and closing the collection tank 110. This type of water tank drainage device 10 is simpler to operate and provides a better user experience.

[0078] For example, such as Figure 3 and 5a , Figure 5b , Figure 6a and Figure 6bAs shown, the filtration mechanism 100 may include an upper mounting ring 113 and a filter basket 114. The filter basket 114 can be inserted into and supported on the upper mounting ring 113. The upper mounting ring 113 may be an annular structure, a cylindrical structure, or other various structures. In the illustrated embodiment, the opening of the filter basket 114 is provided with an outward flange, and a support step is provided inside the upper mounting ring 113. The outward flange can be supported on the support step, so the filter basket 114 can be inserted into and supported on the upper mounting ring 113. In an embodiment not shown, the filter basket 114 may also be threaded to the upper mounting ring 113, wherein the outer side of the filter basket 114 is provided with external threads, and the inner side of the upper mounting ring 113 is provided with internal threads. The filter basket 114 may also be inserted into and supported on the upper mounting ring 113 by snap-fit. Depending on actual needs, the filter basket 114 and the upper mounting ring 113 may have various forms of connection, which will not be elaborated here. Multiple filter holes can be provided on the filter basket 114, and the upper mounting ring 113 and the filter basket 114 can be closed to form a collection trough 110. The filter basket 114 mainly serves a filtering function here; specifically, kitchen waste can accumulate inside the filter basket 114. The filter basket 114 can be supported on the upper mounting ring 113, and the upper mounting ring 113 can be connected to the outside of the collection trough 110. Therefore, the filter basket 114 can be connected to the outside through the upper mounting ring 113.

[0079] like Figure 6a and Figure 6b As shown, when the sealing cap 230 covers the collection tank 110, the food waste processing mechanism 200 can be screwed onto the upper mounting ring 113. Exemplarily, it can be screwed onto the collection tank 110 via the sealing cap 230; or it can be screwed onto the collection tank 110 via the drive assembly 210. In the illustrated embodiment, the drive assembly 210 may be provided with a first fixing protrusion 215, and the upper mounting ring 113 may be provided with an L-shaped groove 118. The first fixing protrusion 215 can engage with the L-shaped groove 118. When the food waste processing mechanism 200 is connected to the upper mounting ring 113, the sealing cap 230 blocks the opening of the collection tank 110; when the food waste processing mechanism 200 is disconnected from the upper mounting ring 113, the sealing cap 230 opens the opening of the collection tank 110. The filter basket 114 is rotatable within the upper mounting ring 113, meaning that the upper mounting ring 113 does not limit the movement of the filter basket 114. When the sealing cover 230 is connected to the upper mounting ring 113, the sealing cover 230 can limit the filter basket 114 in the PP direction of the drive assembly 210, so the upper mounting ring 113 does not need to limit the filter basket 114. This design facilitates the disassembly of the filter basket 114 for maintenance or cleaning.

[0080] The filter basket 114 and the upper mounting ring 113 divide the collection tank 110 into two components. This design facilitates production and makes it easier to disassemble, replace, or repair the collection tank 110 when cleaning is required. The upper mounting ring 113 also allows the collection tank 110 to be adapted to a wider range of applications for external connection. The upper mounting ring 113 can be fixedly installed on the water tank during initial installation, which will be described in more detail later.

[0081] For example, one of the upper mounting ring 113 and the filter basket 114 may be provided with a first limiting groove 1140, and the other of the upper mounting ring 113 and the filter basket 114 may be provided with a first limiting protrusion 1130. Figure 5a , Figure 5b , Figure 6a and Figure 6b As shown, the upper mounting ring 113 may have a first limiting protrusion 1130, and the filter basket 114 may have a first limiting groove 1140. In the illustrated embodiment, three first grooves 111 are evenly arranged circumferentially along the opening of the filter basket 114. Correspondingly, three support protrusions 2140 are evenly arranged circumferentially along the insertion portion 214. When the insertion portion 214 is inserted into the opening of the collection groove 110, the three support protrusions 2140 are respectively inserted into the three first grooves 111, and the sealing cap 230 can seal the collection groove 110. At this time, the insertion portion 214 is actually inserted into the opening of the filter basket 114. When the drive assembly 210 is screwed onto the upper mounting ring 113, since the three support protrusions 2140 are respectively inserted into the three first grooves 111, the filter basket 114 and the drive assembly 210 can rotate together. The screw-on connection between the sealing cap 230 and the upper mounting ring 113 requires that the sealing cap 230 and the upper mounting ring 113 can rotate relative to each other. Along the circumferential direction of the drive assembly 210, the size of the first limiting groove 141 can be larger than the size of the first limiting protrusion 131, allowing the first limiting protrusion 131 to rotate within the first limiting groove 141. Therefore, the upper mounting ring 113 can achieve a screw-on connection with the sealing cap 230. After the sealing cap 230 is screwed onto the upper mounting ring 113, the sealing cap 230 can limit the filter basket 114 in the PP direction of the drive assembly 210 axis. Therefore, with this design, the filter basket 114 has good stability inside the food waste processing mechanism 200. At the same time, this design makes disassembly of the filter basket 114 relatively simple, facilitating user maintenance or cleaning of the food waste processing mechanism 200.

[0082] In another set of embodiments, such as Figure 7 , Figure 8 and Figure 9As shown, the food waste treatment mechanism 200 may include a sealing cover 230', and a drive assembly 210 may be connected to the underside of the sealing cover 230'. The sealing cover 230' may have a similar function to the sealing cover 230 described above, but with a different structure; its function will not be described in detail here. The sealing cover 230' may be detachably connected to the filter mechanism 100. The detachable connection between the sealing cover 230' and the filter mechanism 100 may be in various forms, such as threaded connection, screw-on connection, or snap-on connection. Figure 10a and Figure 10b As shown, the sealing cap 230' is connected to the filter mechanism 100 via a screw-on connection. Similar to the above description, the sealing cap 230' may have a second fixing protrusion 231, and the filter mechanism 100 may have an L-shaped groove 118. The second fixing protrusion 231 can screw into the L-shaped groove 118. When the sealing cap 230' is connected to the filter mechanism 100, the sealing cap 230' blocks the opening of the collection groove 110; when the sealing cap 230' is disconnected from the filter mechanism 100, the sealing cap 230' opens the opening of the collection groove 110. The screw-on connection between the second fixing protrusion 231 and the L-shaped groove 118 is for reference only; the detachable connection between the sealing cap 230' and the filter mechanism 100 can also be in various other forms, which will not be elaborated here.

[0083] The food waste disposal unit 200 may also include a support block 240 and an elastic element 250.

[0084] The support block 240 can be movably disposed on the drive assembly 210 and / or the sealing cover 230' between the first and second workstations. Figure 7 and Figure 8 In the illustrated embodiment, the support block 240 is disposed on the drive assembly 210. The movement of the support block 240 between the first and second working positions can include one or more of the following: translation in the vertical direction, rotation about the central axis PP of the drive assembly, and extension / retraction in the lateral direction (perpendicular to the central axis PP). When the food waste processing mechanism 200 is in the draining state, the support block 240 is in the second working position; when the food waste processing mechanism 200 is in the water-sealing state, the support block 240 is in the first working position; when the food waste processing mechanism 200 switches between the draining and water-sealing states, the support block 240 will switch accordingly between the second and first working positions. Figure 8 As shown, the food waste processing unit 200 is in the drainage state at this time, and the support block 240 is in the second working position. Figure 7 As shown, the food waste processing mechanism 200 is in a water-sealed state at this time, and the support block 240 is in the first working position.

[0085] The elastic element 250 can be connected between the support block 240 and the drive assembly 210, or between the support block 240 and the sealing cover 230'. The elastic element 250 can apply an elastic force to the support block 240 toward the second station. When the food waste treatment mechanism 200 switches from a water-sealing state to a drainage state, the elastic element 250 can apply an elastic force to the support block 240, allowing the support block 240 to move from the first station to the second station.

[0086] In such Figure 7 and Figure 8 In the illustrated embodiment, the elastic element 250 is in the form of a spring, and is disposed between the support block 240 and the drive assembly 210. A second fixing protrusion 231 is provided on the sealing cover 230', and an L-shaped groove 118 is provided on the filter mechanism 100. The sealing cover 230' and the filter mechanism 100 can be connected by a snap-fit ​​mechanism. Figure 8 As shown, when the sealing cap 230' is not connected to the filter mechanism 100, the support block 240 is in the second position, and the elastic element 250 is in its natural state. When the second fixing protrusion 231 is inserted into the L-shaped groove 118, the sealing cap 230' can be connected to the filter mechanism 100 by a screw-on engagement, and the support block 240 can be moved from the second position to the first position. Figure 7 As shown, the sealing cap 230' is connected to the filter mechanism 100 via a snap-fit ​​connection. At this time, the support block 240 is in the first position, and the elastic element 250 is in a stretched state. Alternatively, when the support block 240 is in the second position, the elastic element 250 can be in a stretched state; when the support block 240 is in the first position, the elastic element 250 can be in a further stretched state. When the sealing cap 230' rotates around the central axis of the drive assembly 210, the second fixed protrusion 231 moves to the corner of the L-shaped groove 118. At this time, the snap-fit ​​connection between the sealing cap 230' and the filter mechanism 100 is released, and the elastic element 250 releases its elastic force, allowing the support block 240 to move from the first position to the second position, and the entire device returns to its original position. Figure 8 As shown, the elastic element 250 is in its natural state. The arrangement of the support block 240 and the elastic element 250 makes it easier for the food waste treatment mechanism 200 to switch between a water-sealed state and a drainage state.

[0087] In an embodiment not shown, the elastic element 250 may also be connected between the support block 240 and the sealing cap 230'. In this case, when the support block 240 is in the second position, the elastic element 250 may be in a natural state, and when the support block 240 is in the first position, the elastic element 250 may be in a compressed state; or, when the support block 240 is in the second position, the elastic element 250 may be in a compressed state, and when the support block 240 is in the first position, the elastic element 250 may be in a further compressed state.

[0088] For example, the support block 240 can be supported on the opening edge of the collection tank 110. When the support block 240 is in the second position, its position on the drive assembly 210 can be lower than its position on the drive assembly 210 when it is in the first position. The direction of the elastic force can be vertical. The opening edge of the collection tank 110 can provide vertical support for the support block 240. When the elastic element 250 is disposed between the support block 240 and the drive assembly 210, the position of the support block 240 on the drive assembly 210 when it is in the second position can be lower than its position on the drive assembly 210 when it is in the first position. This means that when the support block 240 is in the first position, the elastic element 250 is in a stretched state. With this configuration, when the support block 240 moves from the first position to the second position, the vertical movement can be powered by the elastic element 250. The user only needs to rotate the food waste processing mechanism 200 around the axis PP of the drive assembly 210.

[0089] In other embodiments not shown, the support block can be telescopically mounted on the drive assembly 210 between the first and second stations in a lateral direction. In this case, the side wall of the collection tank 110 can be provided with a gradually sloping surface from bottom to top. When the sealing cover 230' is disconnected from the filter mechanism 110, the support block extends out of the drive assembly under the action of the elastic member, thereby causing the support block to move upward along the slope.

[0090] For example, such as Figure 7 and Figure 8 As shown, the drive assembly 210 may include a drive housing 211 connected to the sealing cover 230' and a motor 212 disposed within the drive housing 211. The cutter head 220 may be located outside the drive housing 211 and may be connected to the rotating shaft 213 of the motor 212. An opening 2110 may be provided on the side wall of the drive housing 211. The support block 240 may include a connecting part 241 and a supporting part 242. The connecting part 241 may be located inside the drive housing 211, and the supporting part 242 may extend outside the drive housing 211 through the opening 2110. An elastic member 250 may be connected between the connecting part 241 and the drive housing 211 within the drive housing 211. The drive housing 211 can protect the motor 212. The exterior of the drive assembly 210 consists only of a portion of the rotating shaft 213 and a portion of the supporting part 242, thus making the drive assembly 210 more integral and its internal structure more compact, thereby improving the space utilization of the overall device.

[0091] It should be noted that, in Figure 7-9 and Figures 10a-10b In the embodiments shown, and Figure 1-6b In the embodiments shown, the same or similar parts are referred to by the same reference numerals. For the sake of brevity, these same or similar parts will not be described in further detail.

[0092] In yet another set of embodiments, such as Figures 11-14 As shown, the food waste treatment device 200 may also include a water inlet cover 260 and a first water sealing cover 270.

[0093] The drain cover 260 may have a drain hole 261. The size of the drain hole 261 may be larger than the size of the filter hole. The drain hole 261 allows food waste to pass through. The drain cover 260 may cover the collection tank 110 or be embedded in the collection tank 110, and the drive assembly 210 may be connected to the lower part of the drain cover 260. The drain cover 260 may have a shape and size that matches the opening of the collection tank 110, so that the drain cover 260 can be embedded in the opening of the collection tank 110; the drain cover 260 may also be larger in size than the opening of the collection tank 110, so that the drain cover 260 can cover the collection tank 110. The drain cover 260 may be connected to the housing of the drive assembly 210 by various means such as integral molding, welding, snap-fit, or threaded connection. The drive assembly 210 is connected to the lower part of the drain cover 260, which allows the drive assembly to be located inside the collection tank 110, thus enhancing the overall integrity of the device. The first water-sealing cover 270 can be opened and closed to cover the water-passing cover 260, so that the food waste handling device 200 can have both a water-sealed state and a drainage state. For example... Figure 13 As shown, the food waste treatment mechanism 200 is in the draining state, at which time the first water sealing cover 270 opens the water passage cover 260. When the first water sealing cover 270 covers or blocks the water passage cover 260, the food waste treatment mechanism 200 is in the water-sealed state.

[0094] The inclusion of the drain cover 260 and the first sealing cover 270 makes it easier for the food waste disposal mechanism 200 to switch between sealed and drain states, and also simplifies the overall structure of the device. The first sealing cover 270 can replace the existing plug in the sink, thus not increasing the number of removable parts.

[0095] like Figures 11-12 As shown, a drive component positioning part 115 may be provided on the side wall and / or bottom wall of the collection tank 110. The drive component positioning part 115 can support and position the drive component 210. For example, as Figure 12 As shown, the drive assembly positioning part 115 can position the lower part of the drive assembly 210 along the radial direction of the drive assembly 210. Positioning the lower part of the drive assembly 210 by the drive assembly positioning part 115 makes the drive assembly 210 more stable during operation, thereby improving the cutting effect of the cutter head 220 and enhancing the overall stability of the device.

[0096] For example, such as Figure 11As shown, the drive assembly positioning part 115 can support the lower part of the drive assembly 210. The drive assembly 210 is usually quite heavy, and the cutter head 220 is also located below the drive assembly 210. Therefore, by supporting the lower part of the drive assembly 210 with the drive assembly positioning part 115, the stability of the overall device can be improved, making the overall device safer during operation.

[0097] It should be noted that, in Figure 11-15 In the embodiments shown, and Figure 7-9 and Figures 10a-10b In the embodiments shown, the same or similar parts are referred to by the same reference numerals. For the sake of brevity, these same or similar parts will not be described in further detail.

[0098] For example, such as Figure 13 and 14 As shown, the food waste treatment mechanism 200 may further include a sensor 280 and a controller. The sensor 280 can be used to detect the water flow rate in the collection tank 110. The controller can be electrically connected to the sensor 280 and the drive assembly 210. The controller can be used to control the drive assembly 210 according to the water flow rate to control the rotation of the blade head 220. The sensor 280 can be a flow meter, a flow velocity meter, or other various forms of water flow detection device. The controller can be built using electronic components such as timers, comparators, registers, and digital logic circuits, or implemented using processor chips such as microcontrollers, microprocessors, programmable logic controllers (PLCs), digital signal processors (DSPs), field-programmable gate arrays (FPGAs), programmable logic arrays (PLAs), and application-specific integrated circuits (ASICs) and their peripheral circuits. Specifically, when sensor 280 detects a large flow rate of water in the drain device 10, it transmits a signal to the controller, which then controls the drive component 210 to turn on. Conversely, when sensor 280 detects a small flow rate or no water flow in the drain device 10, it transmits a signal to the controller, which then controls the drive component 210 to turn off. It is understood that one or more sensors 280 can be configured as needed. The configuration of sensors 280 and the controller enhances the overall automation level of the device, simplifies user operation, and provides a better user experience.

[0099] For example, such as Figure 13 , Figure 14 and Figure 15As shown, a guide surface 116 can be provided on the side wall of the collection tank 110. The guide surface 116 can be a guide channel, a guide step, or other various forms. The guide surface 116 can rise along the side wall of the collection tank 110 in a spiral and / or stepped manner, and the bottom drain end of the guide surface can be aligned with the sensor 280. The guide surface 116 can guide the water flow entering the collection tank 110 through the opening of the collection tank 110, directing the water flow into the collection tank 110 to the bottom drain end of the guide surface. Aligning the bottom drain end of the guide surface with the sensor 280 allows the sensor 280 to detect changes in water flow with higher accuracy and sensitivity, thus transmitting signals to the controller in a timely manner. The arrangement of the guide surface 116 improves the water flow detection effect of the sensor 280.

[0100] For example, the outer wall of the drive assembly 210 is spaced apart from the inner wall of the collection tank 110 to form an annular channel, and the guide surface 116 can be disposed within the annular channel. The annular channel allows water to immediately converge on the guide surface 116 within the annular channel after entering the collection tank 110. This makes the water flowing out from the bottom drain end of the guide surface 116 more reflective of the water flow rate inside the water tank drainage device 10 at that time, thus further improving the effect of the sensor 280 in detecting water flow rate.

[0101] For example, such as Figure 15 As shown, the guide surface 116 may include a first guide surface 1161 and a second guide surface 1162. Along the circumferential direction of the drive assembly 210, the top water-facing end of the first guide surface 1161 and the bottom drain end of the second guide surface 1162 may be adjacent to each other and may have a first gap 1163 between them, and the bottom drain end of the first guide surface 1161 and the top water-facing end of the second guide surface 1162 may be adjacent to each other and may have a second gap 1164 between them. The arrangement of the first gap 1163 and the second gap 1164 allows the water flow moving on the first guide surface 1161 and the water flow moving on the second guide surface 1162 to not interfere with each other. The guide surface 116 includes a first guide surface 1161 and a second guide surface 1162. Water can flow through the first guide surface 1161 to the drain end at the bottom of the first guide surface 1161, and water can also flow through the second guide surface 1162 to the drain end at the bottom of the second guide surface 1162. The distance that the water travels from the top water-facing end to the bottom drain end on the first guide surface 1161 and the second guide surface 1162 is relatively short. Therefore, this can shorten the path that the water flows on the guide surface 116, reduce the water flow loss when the water flows on the guide surface 116, and further improve the effect of the sensor 280 in detecting water flow.

[0102] For example, sensor 280 can be disposed at the first interval 1163 and / or the second interval 1164. When one sensor 280 is disposed, it can be disposed at either the first interval 1163 or the second interval 1164. When two sensors 280 are disposed, they can be disposed at the first interval 1163 and the second interval 1164 respectively. This design facilitates the removal of the sensors 280 from the food waste processing unit 200.

[0103] For example, sensor 280 can be mounted on drive assembly 210. Sensor 280 and drive assembly 210 can be powered by a power source inside the food waste disposal mechanism 200, which simplifies the circuit structure of sink drain device 10 and makes the overall device structure simpler and easier to implement.

[0104] It should be noted that, although the above text combines... Figure 11-15 The illustrated embodiment describes sensor 280, but sensor 280 can be applied to... Figure 7-9 and Figures 10a-10b The illustrated embodiment, or Figure 1-6b The illustrated embodiment.

[0105] For example, such as Figure 16 As shown, the food waste disposal unit 200 can be detachably connected to the filter unit 100. The detachable connection between the food waste disposal unit 200 and the filter unit 100 can be various forms, such as threaded connection, screw-on connection, or snap-on connection. The sink drain device 10 may include a second sealing cap 300, which can seal the opening of the collection tank 110 when the food waste disposal unit 200 is in the detached state. The sink drain device 10 is installed at the sink drain. When only the sink's water storage function is needed, the food waste disposal unit 200 can be detached, and the opening of the collection tank 110 can be sealed using the second sealing cap 300, thus allowing normal use of the sink's water storage function. The design of the second sealing cap 300 conforms to user habits. When the food waste disposal unit 200 is detached, the method of using the second sealing cap 300 is consistent with the method of using existing sink sealing caps. This design is user-friendly and provides a good user experience.

[0106] For example, return to the reference Figure 3 , Figure 9 and Figure 14The filtration mechanism 100 may include a filter basket 114, on which multiple filter holes may be provided. The filtration mechanism 100 may also include a drain housing 117, with a drain pipe interface 1171 located at the lower part of the drain housing 117. The filter basket 114 can be inserted into the drain housing 117. The filter basket 114 primarily functions as a filter; specifically, food waste can accumulate within it. The filter basket 114 can be supported on the drain housing 117, which can be connected to the outside of the filtration mechanism 100. Therefore, the filter basket 114 can be connected to the outside through the drain housing 117. The drain pipe interface 1171 can be connected to the outside, for example, to a sewer drain. Fine food waste and wastewater flowing from the filter holes of the filter basket 114 can fall into the drain housing 117 and then be discharged through the drain pipe interface 1171. The filter mechanism 100 is more conveniently connected to the outside through the drain housing 117, and the drain housing 117 can protect the internal structure of the filter mechanism 100, making the whole device more stable.

[0107] For example, such as Figure 3 , Figure 9 and Figure 14 As shown, the filtration mechanism 100 may further include an upper mounting ring 113 surrounding the filter basket 114. The upper mounting ring 113 can be connected to the drain housing 117, and an annular mounting groove can be formed between the edges of the upper mounting ring 113 and the drain housing 117. A sealing ring 400 can be provided in the mounting groove, and the edge of the drain outlet 21 of the water tank can be inserted into the mounting groove. When the upper mounting ring 113, the drain housing 117, and the drain outlet 21 of the water tank are installed, there is a mounting groove between the upper mounting ring 113 and the edge of the drain outlet 21 of the water tank, and the sealing ring 400 is sandwiched in the mounting groove; there is also a mounting groove between the drain housing 117 and the edge of the drain outlet 21 of the water tank, and the sealing ring 400 is also sandwiched in the mounting groove. Figure 9 In the illustrated embodiment, the upper mounting ring 113 has an annular structure, the drain housing 117 has a cylindrical structure, the drain pipe interface 1171 is funnel-shaped, and the drain pipe interface 1171 is coaxial with the drain housing 117. Figure 3 In the illustrated embodiment, the upper mounting ring 113 has an annular structure, the drain housing 117 has a cylindrical structure, the drain pipe interface 1171 has a cylindrical structure, and the drain pipe interface 1171 is coaxial with the drain housing 117. Figure 14 In the embodiment shown, the upper mounting ring 113 has an annular structure, the drain housing 117 has a cylindrical structure, the drain pipe interface 1171 has a funnel shape, and the drain pipe interface 1171 is coaxial with the drain housing 117. Figure 14In the embodiment shown, the drain housing 117 is directly connected to the filter basket 114, and the upper mounting ring 113 is disposed on the outside of the drain housing 117. At this time, the first limiting protrusion 1130 is disposed on the drain housing 117. Figure 3 , Figure 9 and Figure 14 The illustrated embodiment is for reference only. Depending on actual needs, the upper mounting ring 113 and the drain housing 117 can also have various other structures. The upper mounting ring 113 and the filter basket 114 can be closed to form a collection trough 110, and the food waste treatment mechanism 200 can be connected to the upper mounting ring 113. The upper mounting ring 113 can be connected to the drain housing 117 by various methods such as threaded connection, snap-fit, or interference fit. Typically, a sealing ring 400 can be provided in the mounting groove between the upper mounting ring 113 and the drain housing 117, and the upper mounting ring 113 and the drain housing 117, together with the sealing ring 400, can be connected to the drain outlet 21 of the external water tank.

[0108] For example, one of the upper mounting ring 113 and the filter basket 114 may be provided with a limiting groove, and the other of the upper mounting ring 113 and the filter basket 114 may be provided with a limiting protrusion. Figure 3 , Figure 5a , Figure 5b , Figure 6a , Figure 6b ,and Figure 14 As shown, the upper mounting ring 113 may have a first limiting protrusion 1130, and the filter basket 114 may have a first limiting groove 1140. In this way, the upper mounting ring 113 can restrict the rotation of the filter basket 114, making the overall device more stable.
