Technical Field

[0001] The utility model belongs to the technical field of garbage disposal, and in particular relates to a kitchen waste disposer. Background Art

[0002] The general structure of existing food waste disposers is similar, including a casing with a feed port and a discharge port, a crushing element arranged in the casing, and a driving mechanism for driving the crushing element to work. The crushing element can crush the food waste entering from the feed port under the drive of the driving mechanism.

[0003] Specifically, the Chinese utility model patent "A kitchen waste disposer" with patent number 202221965311.8 and authorization announcement number CN218292145U includes a casing and a grinding cover, a grinding disc is installed inside the grinding cover, the grinding cover includes an upper grinding cover and a lower grinding cover, the upper grinding cover has a feeding port on the top, the lower grinding cover has a discharge port, an annular wall is installed on the inner circumferential wall of the lower side of the upper grinding cover, the annular wall is arranged above the grinding disc, an annular cavity is formed between the annular wall and the upper grinding cover, a water inlet connected to the annular cavity is opened on the outer circumferential wall of the upper grinding cover, a water outlet is opened on the inner wall of the annular cavity, and an annular cutter that can rotate under the action of water pressure is installed in the annular cavity.

[0004] Another example is the Chinese utility model patent "A kitchen waste treatment system" with patent number 202321652436.X and authorization announcement number CN220538788U, which includes a sink and a garbage disposer arranged under the sink, the garbage disposer includes a grinding chamber and a grinding disc arranged in the grinding chamber, the grinding chamber has a discharge port, and the discharge port is arranged below the grinding disc. It is characterized in that: a step structure is formed at the bottom of the sink, a main feeding port is opened at the top of the step structure, a feeding cover is installed on the main feeding port, and the top of the grinding chamber is installed on the main feeding port.

[0005] In addition to considering the grinding effect, the design of existing food waste disposers must also consider the user experience and safety of use, such as the convenience of users when putting in garbage, whether the garbage will splash out from the feed port during disposal, etc. In order to avoid splashing out from the feed port during disposal, a feeding cover is generally set at the feed port. When feeding, the feeding cover is opened to expose the feed port. After feeding, the feeding cover is covered for garbage disposal. However, sometimes people forget to cover the feeding cover after feeding. At this time, when the machine is running, the hand can reach into the garbage disposer through the feed port, and the garbage is easily splashed out from the feed port during disposal, which poses certain safety hazards. Utility Model Content

[0006] The first technical problem to be solved by the utility model is to provide a kitchen waste disposer which is convenient for disposing of garbage in view of the current status of the prior art.

[0007] The second technical problem to be solved by the utility model is to provide a kitchen waste disposer to improve the safety of use.

[0008] The technical solution adopted by the utility model to solve the above-mentioned first technical problem is: a kitchen waste disposer, comprising:

[0009] A casing having a crushing chamber inside, a feeding port is provided at the top of the crushing chamber, and a discharge port is provided at the bottom of the crushing chamber;

[0010] A crushing element is arranged in the crushing chamber and is used to crush the garbage entering from the feed inlet;

[0011] A driving mechanism, the output end of which acts on the crushing member to drive the crushing member to work;

[0012] A feeding cover is arranged at the feeding port of the pulverizing chamber;

[0013] The feature of the invention is that the feeding cover comprises:

[0014] An outer cover is arranged at the feed inlet to cover the feed inlet, and the outer cover is arranged to be able to be separated from the feed inlet upward to open the feed inlet. At the same time, a feeding inlet is provided in the center of the outer cover and is connected vertically;

[0015] A handle constrained with the outer cover is disposed at the center of the feeding port, and at least partially extends upward relative to the feeding port to form a vertical portion;

[0016] The inner cover is an annular cover, whose inner circumferential edge is circumferentially located on the outer circumference of the vertical portion of the handle and is adjacent to or in contact with the side wall of the vertical portion, and whose outer circumferential edge is located on the periphery of the feeding port. The inner cover is arranged to be able to move up and down along the vertical portion and be relatively away from the feeding port or relatively close to the feeding port.

[0017] In this way, when a large amount or a large volume of kitchen waste needs to be fed in, the user can lift the handle to open the outer cover upwards and expose the feeding port, and the kitchen waste directly enters the crushing chamber of the casing through the feeding port; on the contrary, when the kitchen waste is less or the volume is smaller, the outer cover can be covered, and the inner cover can be moved upwards so that the inner cover is relatively away from the feeding port. At this time, the kitchen waste enters the crushing chamber of the casing through the feeding port; after the feeding is completed, the inner cover can be moved downwards to make the inner cover relatively close to the feeding port. At this time, the feeding port is basically blocked by the inner cover to prevent kitchen waste from splashing out of the feeding port when the machine is running.

[0018] Preferably, the inner cover is arranged to be movable downward to a first position to close the feeding opening.

[0019] Preferably, the edge of the feeding port extends upward to form an upper folding edge, and the outer peripheral edge of the inner cover extends downward to form a lower folding edge, the lower folding edge is located at the periphery of the upper folding edge and the two are arranged at intervals to form a ring seam, and when the inner cover is in the first position, the lower end of the lower folding edge is attached to the supporting surface of the outer cover located at the periphery of the feeding port. The setting of the upper and lower folding edges can play a guiding role and further prevent garbage from splashing out of the feeding port when the machine is running.

[0020] Preferably, the inner cover is arranged on the periphery of the vertical portion of the handle in a circumferentially rotatable manner;

[0021] A conversion component is provided between the upper folding edge and the lower folding edge, which can convert the circumferential rotational motion of the lower folding edge into a conversion component that enables the lower folding edge to move up and down relative to the upper folding edge.

[0022] The inner cover can be driven to move up and down by rotating the inner cover, which is easy to operate.

[0023] Furthermore, the conversion component includes:

[0024] A first protrusion, provided on the outer side surface of the upper folding edge;

[0025] A second protrusion is arranged on the inner side surface of the lower fold edge, and the second protrusion has a lower end surface which is arranged downward and extends along the circumference of the lower fold edge, and the lower end surface has a first inclined portion which is inclined downward along a first direction clockwise or counterclockwise, and a first horizontal portion which extends horizontally along the first direction from the lower end of the first inclined portion; the first horizontal portion is supported on the first protrusion so that the inner cover is relatively far away from the feeding port, and at the same time, as the inner cover rotates, the first protrusion can move along the first inclined portion of the lower end surface so that the inner cover moves downward to a first position relatively close to the feeding port.

[0026] Furthermore, the second protrusion also has an upper end surface arranged upward and extending along the circumference of the lower folded edge, and the upper end surface has a second inclined portion inclined downward along the first direction, and a second horizontal portion extending horizontally from the upper end of the second inclined portion along a second direction opposite to the first direction;

[0027] The outer side surface of the upper fold edge is also provided with a third protrusion, which is arranged circumferentially with the first protrusion, and when the inner cover is in the first position, the third protrusion passes through the second inclined portion of the upper end surface of the second protrusion and is supported on the second horizontal portion.

[0028] In this way, when in the first position, the third protrusion is supported on the second horizontal portion, which can limit the inner cover and prevent the inner cover from accidentally moving upward.

[0029] Preferably, the lower fold edge includes a fold edge body extending downward from the outer peripheral edge of the inner cover, and a sealing ring located circumferentially inside the fold edge body, the outer peripheral surface of the sealing ring is in contact with the inner peripheral surface of the fold edge body, and the inner peripheral surface of the sealing ring serves as the inner side surface of the lower fold edge and is spaced apart from the upper fold edge; at the same time, the sealing ring and the lower fold edge are constrained together and can move together, and when the inner cover is in the first position, the lower end surface of the sealing ring is in contact with the support surface of the outer cover located outside the feeding port.

[0030] Furthermore, it also includes a sealing ring, which is circumferentially sleeved on the outer periphery of the vertical portion of the handle, and when the inner cover is relatively far away from the feeding port, the sealing ring is located below the inner circumference of the inner cover, and when the inner cover is in the first position, the sealing ring fits against the inner circumference of the inner cover.

[0031] Furthermore, when the inner cover is in the first position, a portion of the inner cover adjacent to the outer peripheral edge is attached to the upper end surface of the upper folded edge.

[0032] In the above solution, preferably, the handle further has a horizontal stop, which is arranged above the vertical portion and is arranged in a T-shape with the vertical portion. The horizontal stop can limit the movement of the inner cover to prevent the inner cover from moving upward and separating from the handle. The arrangement of the horizontal stop is convenient for users to carry the bag by hand.

[0033] To further solve the second technical problem mentioned above, preferably, it also includes a magnetic induction switch and a magnetic part, which are respectively arranged on the casing and the outer cover, and the magnetic induction switch is electrically connected to the driving mechanism. When the outer cover is separated from the feed port, the magnetic part is located outside the sensing area of ​​the magnetic induction switch; when the outer cover is located at the feed port, the magnetic part triggers the magnetic induction switch so that the driving mechanism can drive the crushing parts to work.

[0034] The design of the magnetic part and the magnetic induction switch electrically connected to the driving mechanism in the utility model ensures that the driving mechanism can drive the crushing part to work and crush the kitchen waste only when the feeding cover is set at the feeding port, thereby ensuring safe use.

[0035] Preferably, the magnetic member is arranged on the outer cover, and the magnetic induction switch is arranged on the casing.

[0036] Preferably, there are at least two magnetic parts, and when the outer cover is located at the feed inlet, the magnetic parts are arranged at intervals in the circumferential direction of the feed inlet, and the magnetic induction switch is located on one side of the periphery of each magnetic part and can be triggered by at least one of the magnetic parts. In this way, the feeding cover can trigger the induction switch when it is placed at the feed inlet at any position.

[0037] Furthermore, there are at least two magnetic induction switches, which are arranged at intervals along the circumferential direction. When the outer cover is located at the feed port, at least one of the magnetic induction switches can be triggered by the magnetic member.

[0038] Furthermore, there are six magnetic parts arranged at equal intervals along the circumferential direction, there are two magnetic induction switches, and the angle between the line connecting one of the magnetic induction switches and the corresponding circumferential center and the angle between the line connecting the other magnetic induction switch and the corresponding circumferential center is 45°.

[0039] In the above scheme, preferably, each magnetic induction switch is arranged on the outside of the housing through the same box body, and the box body is in an arc shape extending circumferentially, and a cavity is provided in the box body for each magnetic induction switch to be constrained therein.

[0040] In order to constrain the box body and the housing together, preferably, both ends of the box body in the extension direction are provided with C-shaped sockets that can cooperate with the screws on the kitchen waste disposer, so that the corresponding screws can be inserted horizontally. This facilitates the assembly between the box body and the housing, and no additional mounting structure is required.

[0041] In order to improve the structural stability and prevent the box body from accidentally detaching from the casing, preferably, a torsion spring that can constrain the screw in the socket is provided at the C-shaped socket, and one end of the torsion spring is located in the C-shaped socket so that the screw always has a tendency to move into the C-shaped socket.

[0042] Furthermore, the box body is formed by an arc-shaped base and an upper cover which are butt-jointed one above the other.

[0043] Preferably, the magnetic induction switch is a reed switch; and the magnetic member is a permanent magnet.

[0044] Compared with the prior art, the advantages of the present invention are: when a large amount or a large volume of kitchen waste needs to be fed, the user can lift the handle to open the outer cover upwards and expose the feeding port, and the kitchen waste directly enters the crushing chamber of the casing through the feeding port; on the contrary, when the kitchen waste is less or the volume is smaller, the outer cover can be covered, and the inner cover can be moved upwards to make the inner cover relatively away from the feeding port. At this time, the kitchen waste enters the crushing chamber of the casing through the feeding port; after the feeding is completed, the inner cover can be moved downwards to make the inner cover relatively close to the feeding port. At this time, the feeding port is basically blocked by the inner cover to prevent the kitchen waste from splashing out of the feeding port when the machine is running.
