Description

Technical Field

[0001] The utility model relates to the technical field of garbage disposers, in particular to a quick-release connection structure between a garbage disposer and a water tank and garbage disposing equipment. Background Art

[0002] A food waste disposer is usually installed on a kitchen sink and connected to the water outlet of the sink so that food waste falls into the disposer through the water outlet of the sink, and the food waste can be ground and pulverized by the disposer and discharged to a sewage pipe along with water. Generally, a garbage disposer is usually connected to the water outlet of the sink through a sink flange assembly, wherein the sink flange assembly is threadedly connected to the garbage disposer. However, during the grinding and pulverizing process of such a garbage disposer, its grinding motor will vibrate, and the sink flange assembly is prone to loosening relative to the garbage disposer during long-term use.

[0003] To this end, the Chinese utility model patent application with application number CN202122391377.2 (authorization announcement number: CN216195186U) discloses a garbage disposer for a sink and its connecting assembly, including: a water discharge assembly, including a water discharge cylinder for connecting to the sink, and a fixed plate; the fixed plate includes a fixing ring mounted on the water discharge cylinder, and a barb portion is provided on the side of the fixing ring away from the connection between the water discharge cylinder and the sink; a garbage disposer interface assembly, including a garbage disposer interface part and a main body clamping ring sleeved on the mouth of the garbage disposer interface part; the main body clamping ring is provided with a clamping protrusion clamped to the barb portion; and an anti-drop buckle, provided on the clamping protrusion, and the anti-drop buckle is buckled on the barb portion at one end away from the clamping protrusion. The water launch cylinder includes a water launch main body and a flange portion coaxially arranged on one axial side of the water launch main body; the fixed plate also includes a movable pressure ring movably sleeved on the water launch main body and located between the flange portion and the fixed ring, and an operating component connecting the movable pressure ring and the fixed ring; the operating component is configured to be able to drive the movable pressure ring to axially displace relative to the fixed ring. The operating component includes an operating member and a hinged member, the operating member having a manual operating end and a connecting end arranged oppositely, the connecting end being hinged to the fixed ring; one end of the hinged member is hinged to a portion of the operating member located between the manual operating end and the connecting end, and the other end is hinged to the movable pressure ring; the first hinge axis of the operating member and the second hinge axis of the hinged member are parallel to each other and are both parallel to the radial direction of the movable pressure ring. When installing the garbage disposer connecting assembly, lift the operating part of the operating assembly upward so that the movable pressure ring of the fixed plate moves toward the flange part and is pressed against the side of the second sealing ring away from the bottom plate. In the axial direction of the movable pressure ring, the flange part and the fixed plate can be pressed and fixed on both sides of the bottom plate respectively. With the help of three sets of operating assemblies, the fixed plate can be firmly installed at the water outlet.

[0004] However, the connection structure between the garbage disposer and the sink in the above patent application still has certain shortcomings. The movable pressure ring used to press upward on the bottom plate of the sink only relies on the operating member and the hinged member hinged together to keep the movable pressure ring pressed against the bottom of the sink when they are rotated to the extreme position. This locking method is not reliable, especially when the garbage disposer vibrates severely during operation. The operating member is easily affected by the vibration of the garbage disposer and resets in the opposite direction, thereby releasing the upward pressure on the movable pressure ring, resulting in failure of the seal between the sink and the drain tube. Utility Model Content

[0005] The first technical problem to be solved by the utility model is to provide a quick-release connection structure between a garbage disposer and a sink in view of the current status of the prior art, wherein the quick-release connection structure can make the locking between the downpipe and the sink more secure and less likely to loosen.

[0006] The first technical problem to be solved by the utility model is to provide a garbage disposal device using the above-mentioned quick-release connection structure in view of the current status of the prior art.

[0007] The technical solution adopted by the utility model to solve the first technical problem is: a quick-release connection structure between a garbage disposer and a water tank, comprising:

[0008] A downpipe, the upper end of which has an annular flange extending radially outward, the annular flange can be limited at the top of the outer peripheral edge of the installation opening of the sink, and the lower end of the downpipe can be inserted into the connection port of the garbage disposer;

[0009] A locking ring is rotatably connected to the outer peripheral wall of the downpipe and can move upward to press against the bottom of the outer peripheral edge of the installation opening of the water tank;

[0010] The self-locking assembly is arranged on the upper part of the garbage disposer, including a mounting sleeve and a support frame. The mounting sleeve is arranged outside the downpipe and is rotated and limited on the downpipe together with the garbage disposer. During the rotation of the garbage disposer and the mounting sleeve relative to the downpipe, the two move away from each other in the up and down directions. The bottom of the mounting sleeve has a horizontal through hole. The main body of the support frame is in the shape of a long strip and is inserted into the through hole of the mounting sleeve. The support frame as a whole can swing up and down with the position of the through hole of the mounting sleeve as a fulcrum. During the downward movement of the garbage disposer relative to the mounting sleeve, the garbage disposer can press the first end of the support frame downward to make the second end of the support frame warp up, so that the second end of the support frame directly or indirectly presses upward on the bottom of the locking ring.

[0011] In order to make the force of the locking ring pressing against the bottom of the outer peripheral edge of the installation opening of the sink more uniform, the installation sleeve has at least two first arms that are arranged in sequence along its circumference and extend downward. Each of the first arms is provided with the through hole, and the support frame also has at least two corresponding ones, which are respectively arranged in the through holes of the corresponding first arms.

[0012] Taking into account that there is a certain distance between the locking ring and the support frame in the up and down directions, and the swing amplitude of the support frame in the through hole is limited, in order to enable the second end of the support frame to be firmly pressed against the bottom of the locking ring, the second end of the support frame has an upwardly extending support rod, and the top of the support rod can directly or indirectly press against the bottom of the locking ring.

[0013] Generally, the second end of the support frame can be directly pressed against the bottom of the locking ring, but in order to make the bottom of the locking ring more evenly stressed and to ensure the overall aesthetics of the quick-release connection structure, it also includes a support outer frame that is mounted outside the mounting sleeve and each of the support frames, and the support outer frame is movably limited up and down between the locking ring and the garbage disposer, and the top edge of the support outer frame has a support stop edge extending radially inward, and the top of the support rod is against the bottom of the support stop edge, and drives the support outer frame to move upward during the upward process, and makes the support stop edge press upward against the bottom of the locking ring.

[0014] In order to limit the garbage disposer above the first end of the support frame, the upper part of the garbage disposer also has a first limit stop extending toward the first end of the support frame and limiting the upward movement of the first end above the first end of the support frame.

[0015] In order to make the garbage disposer and the mounting sleeve move away from each other in the vertical direction during the rotation process relative to the downpipe, the garbage disposer has a second limiting protrusion protruding toward the center of the connecting port at a position adjacent to the connecting port, the mounting sleeve has a third limiting protrusion extending radially inward, and the outer peripheral wall of the downpipe has a second limiting convex rib protruding radially outward and extending along its circumference, the two ends of the second limiting convex rib are respectively recorded as the starting end and the end, the upper side surface and the lower side surface of the second limiting convex rib are gradually inclined downward from the starting end to the end of the second limiting convex rib, and the inclination angle of the lower side surface of the second limiting convex rib relative to the horizontal plane is greater than the inclination angle of the upper side surface relative to the horizontal plane;

[0016] During the rotation of the garbage disposer and the mounting sleeve relative to the downpipe, the second limiting protrusion of the garbage disposer slides with the lower side surface of the second limiting rib, and the third limiting protrusion of the mounting sleeve slides with the upper side surface of the second limiting rib.

[0017] It is conceivable that the upper side surface of the second limiting rib can also extend substantially in the horizontal direction or extend slightly upwardly inclined. In addition, two independent limiting ribs spaced apart from each other can be provided on the outer peripheral wall of the downpipe, respectively slidingly cooperating with the second limiting protrusion of the garbage disposer and the third limiting protrusion of the mounting sleeve, wherein the inclination angle of at least the lower side surface of the lower limiting rib is greater than the inclination angle of at least the upper side surface of the upper limiting rib.

[0018] In order to enable the garbage disposer to drive the mounting sleeve to rotate when it rotates, the mounting sleeve has at least two second arms which are arranged in sequence along its circumference and extend downward, and the upper part of the garbage disposer has at least two limiting slots for the lower ends of the second arms of the mounting sleeve to be inserted into accordingly.

[0019] In order to keep the installation sleeve and the garbage disposer as far away from each other as possible, so that the third limiting protrusion of the installation sleeve and the second limiting protrusion of the garbage disposer can be conveniently matched on the upper and lower side surfaces of the second limiting rib during initial installation, the self-locking assembly also includes:

[0020] The elastic member acts on the support frame and makes the second end of the support frame always have a tendency to swing upward.

[0021] The above-mentioned elastic member can adopt various existing technologies and may include various elastic elements such as compression springs, torsion springs, and spring leaves. However, in order to better cooperate with the above-mentioned support frame, the elastic member is a spring, and the bottom of the support frame has a placement groove for accommodating the upper end of the spring. The garbage disposer has an upwardly extending extension rod at a position corresponding to the position below the second end of the support frame, and the lower end of the spring is sleeved on the extension rod.

[0022] The technical solution adopted by the utility model to solve the second technical problem is: a garbage disposal device, including a garbage disposal device that can be installed under a sink through a quick-release connection structure, and the quick-release connection structure adopts the quick-release connection structure between the garbage disposal device and the sink mentioned above.

[0023] Compared with the prior art, the utility model has the following advantages: when the locking ring is screwed into place and pressed against the bottom of the outer peripheral edge of the installation opening of the water tank, the garbage disposer and the installation sleeve are rotated relative to the downpipe, and the garbage disposer and the installation sleeve can move away from each other in the vertical direction, wherein, when the garbage disposer moves downward relative to the installation sleeve, it can press downward against the first end of the support frame to make the second end of the support frame tilt upward, and then the second end of the support frame directly or indirectly presses upward against the bottom of the locking ring, that is, (using the principle of lever) gives the locking ring an upward thrust, so that the water tank and the locking ring achieve a higher sealing and waterproof effect. On the other hand, since the locking ring is subjected to an upward thrust by the support frame, the locking ring is not easy to loosen even during the vibration of the garbage disposer.

[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0034] In the specification and claims of the present invention, terms indicating directions, such as "front", "rear", "up", "down", "left", "right", "side", "top", "bottom", etc., are used to describe various exemplary structural parts and elements of the present invention, but these terms are used here only for the purpose of convenience of description and are determined based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in the present invention can be arranged in different directions, these terms indicating directions are only used as explanations and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0035] Figure 1-Figure 9 A preferred embodiment of the quick-release connection structure between the garbage disposer and the water tank of the utility model is shown. The quick-release connection structure between the garbage disposer and the water tank includes a downpipe 3, a flexible sealing ring 11, a locking ring 2, and a self-locking assembly. The water tank 1 of this embodiment only shows a partial structure of its bottom wall in the accompanying drawings, wherein the bottom wall of the water tank 1 has a mounting opening 10 that runs through from top to bottom, and the outer peripheral edge of the bottom wall of the water tank 1 where the mounting opening 10 is located is partially concave to form an annular sink 100, and the top surface of the bottom wall of the annular sink 100 is an inclined surface that is inclined from the outer periphery to the center position of the mounting opening 10. The garbage disposer 4 of this embodiment also only shows the upper cover structure of the crushing chamber in the accompanying drawings, and the upper cover of the garbage disposer 4 has a connecting opening 40 for the lower end of the downpipe 3 to extend into.

[0036] See also Figure 3 The downpipe 3 extends vertically as a whole, and its upper end is connected to the mounting port 10 of the water tank 1, while the lower end is used to connect to the connection port 40 of the garbage disposer 4. The downpipe 3 includes a main body and an annular flange 31 located at the upper end of the main body and extending radially outward. The radial dimension of the annular flange 31 matches the radial dimension of the annular sink 100 of the water tank 1, so that the annular flange 31 can be placed in the annular sink 100 at the top of the outer peripheral edge of the mounting port 10 of the water tank 1.

[0037] A second sealing ring 8 is embedded at the upper edge of the connection port 40 of the garbage disposer 4. The second sealing ring 8 has an annular lip structure with a diameter that gradually shrinks from top to bottom, and the lip structure can be wrapped around the outer peripheral wall of the downpipe 3. Specifically, when the main body of the downpipe 3 is installed into the connection port 40 of the upper cover, the second sealing ring 8 will be squeezed and deformed, so that it can be tightly attached to the upper cover and the main body of the downpipe 3, achieving a waterproof sealing effect, and the waterproof performance will not be affected even if the two slide up and down.

[0038] The flexible sealing ring 11 includes a radial extension portion 111 and an axial extension portion 112 extending downward from the inner side of the radial extension portion 111. The radial extension portion 111 is also placed in the annular sink 100 of the sink 1 and is pressed downward by the annular flange 31 of the downpipe 3. The axial extension portion 112 is sleeved on the outer peripheral wall of the main body of the downpipe 3 and fits with the outer peripheral wall of the main body of the downpipe 3. The diameter of the installation opening 10 of the sink 1 is smaller than the outer diameter of the axial extension portion 112 of the flexible sealing ring 11. After the flexible sealing ring 11 is installed in the installation opening 10 of the sink 1, the axial extension portion 112 of the flexible sealing ring 11 and the peripheral edge of the installation opening 10 of the sink 1 are interference fit. In this way, after the flexible sealing ring 11 is installed, the flexible sealing ring 11 and the peripheral edge of the installation opening 10 of the sink 1 can effectively achieve a waterproof sealing effect. After the flexible sealing ring 11 is installed with the water tank 1, the downpipe 3 is installed in the flexible sealing ring 11. After the downpipe 3 is installed, the downpipe 3 will squeeze and deform the flexible sealing ring 11, so that the downpipe 3 and the flexible sealing ring 11 are closely fitted, so that they can achieve waterproof sealing. The matching surface between the downpipe 3 and the flexible sealing ring 11 is relatively long. The advantage of this design is that even if the downpipe 3 is loose or not installed properly, it can be ensured that this matching can fully achieve a good waterproof sealing. The inner peripheral wall of the axial extension part 112 also has an annular protrusion 1120 extending radially inward. The inner diameter of the annular protrusion 1120 is smaller than the outer diameter of the downpipe 3. When the downpipe 3 is installed in the axial extension part 112 of the flexible sealing ring 11, the annular protrusion 1120 is squeezed by the downpipe 3 so that the entire axial extension part 112 is inclined toward the side away from the downpipe 3 and is limited below the outer peripheral edge of the installation opening 10 of the water tank 1. That is, the downpipe 3 and the axial extension portion 112 (specifically the annular protrusion 1120) of the sealing ring of the sink 1 are tightly mounted. Therefore, the axial extension portion 112 of the sealing ring of the sink 1 is deformed by the squeezing of the main body of the downpipe 3. After the deformation, the flexible sealing ring 11 and the peripheral edge of the mounting opening 10 of the sink 1 will cooperate to produce an inverted structure. The inverted structure can make it more difficult for the flexible sealing ring 11 to separate from the mounting opening 10 of the sink 1, so that the three parts of the sink 1, the flexible sealing ring 11 and the downpipe 3 are precisely matched, and can always maintain a sealed and waterproof state even in the case of loose fitting or shaking.

[0039] The locking ring 2 is sleeved outside the main body of the downpipe 3 and is located below the bottom wall of the water tank 1. The locking ring 2 is rotatably connected to the downpipe 3 in a rotatable and snap-fitting manner relative to the downpipe 3. When the locking ring 2 is rotated and locked in place relative to the downpipe 3, it abuts against the bottom of the outer peripheral edge of the installation opening 10 of the water tank 1, so that the annular flange 31 of the downpipe 3 presses the radial extension 111 of the flexible sealing ring 11 downward.

[0040] An annular relief groove 23 is also provided on the inner side of the locking ring 2 at a position corresponding to the annular protrusion 1120 of the flexible sealing ring 11 for the annular protrusion 1120 (squeezed by the downpipe 3) to deform outwards.

[0041] See also Figure 6 The outer peripheral wall of the main body of the downpipe 3 has a first limiting rib 32 protruding radially outward and extending along its circumferential direction. The first limiting rib 32 is gradually inclined upward along the locking rotation direction of the locking ring 2. That is, the upper side surface of the first limiting rib 32 is a first inclined surface 321 gradually inclined upward along the locking rotation direction of the locking ring 2. Specifically, the first limiting rib 32 has at least two first limiting ribs arranged in sequence along the circumference of the downpipe 3. Correspondingly, the inner wall of the locking ring 2 has a first limiting protrusion 21 extending radially inward and slidably fitting on the first inclined surface 321 of the first limiting rib. Similarly, the first limiting protrusion 21 also has at least two first limiting protrusions arranged in sequence along the circumference of the locking ring 2. As a result, the outer peripheral edge of the installation opening 10 of the sink 1 can be more evenly stressed along the bottom (pressed by the locking ring 2), and the sealing between the sink 1, the flexible sealing ring 11 and the downpipe 3 is better ensured.

[0042] The first inclined surface 321 of the first limiting convex rib is also provided with stop ribs 3210 arranged in sequence and at intervals along the extension direction of the first limiting convex rib 32. The stop ribs 3210 can be limited with the first limiting protrusion 21 of the locking ring 2, thereby preventing the locking ring 2 from loosening after being locked in place. Of course, the stop ribs 3210 of this embodiment can also give the operator a locking feel prompt.

[0043] In order to prevent the locking ring 2 from being disengaged from the end position of the first limiting rib 32 due to excessive force during the tightening process, the end position of each first limiting rib 32 of the downpipe 3 is also provided with a second limiting stopper 322 extending upward along the locking rotation direction of the locking ring 2. When the locking ring 2 is rotated to the limit position along the tightening direction, it abuts against the second limiting stopper 322, thereby prompting the user to rotate the locking ring 2 to the limit locking position. In order to ensure the strength of the first limiting rib 32, the position where the main body of the downpipe 3 connects with the annular flange 31 is provided with an annular boss 33 protruding radially outward, the above-mentioned first limiting rib 32 is located below the annular boss 33, and the upper end of the first limiting stopper 410 is connected to the annular boss 33. The annular protrusion 1120 of the axial extension 112 of the flexible sealing ring 11 abuts against the outer wall surface of the annular boss 33 of the downpipe 3. In order to prevent the locking ring 2 from loosening due to reverse rotation, the top surface of the locking ring 2 is also provided with anti-slip grooves 22 that contact the bottom of the outer peripheral edge of the installation opening 10 of the sink 1.

[0044] See also Figure 5-Figure 9The self-locking assembly includes a mounting sleeve 5, a support frame 6, an elastic member 63 and a support outer frame 7.

[0045] The mounting sleeve 5 is annular in shape and is mounted outside the downpipe 3. The outer peripheral wall of the main body of the mounting sleeve 5 has at least two first arms 51 extending downward and evenly spaced along the circumference thereof. Fig. 9 As shown, the installation sleeve 5 of this embodiment is provided with three first arms 51. The bottom of each first arm 51 has a horizontally opened through hole 510, and the through hole 510 can be used for the support frame 6 to pass through. The outer peripheral wall of the main body of the installation sleeve 5 of this embodiment is also provided with at least two second arms 52 extending downward and evenly spaced along its circumference. Similarly, the installation sleeve 5 of this embodiment is also provided with three second arms 52. Correspondingly, the top of the garbage disposer 4 has a limiting slot 43 for the lower end of each second arm 52 to be inserted into. Therefore, when the garbage disposer 4 rotates relative to the downpipe 3, the installation sleeve 5 is also driven to rotate together. More specifically, see Figure 7 The inner wall of the main body of the mounting sleeve 5 has a limit groove 54 extending up and down, and the limit groove 54 extends downward to the bottom of the mounting sleeve 5 and forms an opening. The top of the garbage disposer 4 has a second extension wall 42 extending upward and extending into the limit groove 54 of the mounting sleeve 5. After the second extension wall 42 extends into the limit groove 54 of the mounting sleeve 5, the garbage disposer 4 and the mounting sleeve 5 can also be limited in the circumferential direction, thereby ensuring that the mounting sleeve 5 can rotate relative to the downpipe 3 together with the garbage disposer 4.

[0046] The upper end of the second extension wall 42 of the garbage disposer 4 is also formed with a second limiting protrusion 420 protruding radially inward. The inner wall of the mounting sleeve 5 is provided with a third limiting protrusion 53 extending radially inward at a position corresponding to the upper position of the second limiting protrusion 420. The outer peripheral wall of the main body of the downpipe 3 is provided with a second limiting rib 34 protruding radially outward and extending along its circumferential direction, and the position of the second limiting rib 34 is located below the first limiting rib 32. The two ends of the second limiting rib 34 are respectively recorded as the starting end and the end, wherein the upper side surface and the lower side surface of the second limiting rib 34 are gradually inclined downward from the starting end to the end of the second limiting rib 34, and the inclination angle of the lower side surface of the second limiting rib 34 relative to the horizontal plane is greater than the inclination angle of the upper side surface relative to the horizontal plane. During the rotation of the garbage disposer 4 and the mounting sleeve 5 relative to the downpipe 3, the second limiting protrusion 420 of the garbage disposer 4 is slidably matched with the lower side surface of the second limiting rib 34, and the third limiting protrusion 53 of the mounting sleeve 5 is slidably matched with the upper side surface of the second limiting rib 34. Specifically, during the rotation of the garbage disposer 4 and the mounting sleeve 5 relative to the downpipe 3 (the rotation process from the starting end to the end of the second limiting rib 34), since the inclination angle of the lower side surface of the second limiting rib 34 relative to the horizontal plane is greater than the inclination angle of the upper side surface relative to the horizontal plane, the mounting sleeve 5 and the garbage disposer 4 will move away from each other in the vertical direction. More specifically, the third limiting protrusion 53 of the present embodiment is a long strip-shaped protrusion extending along the circumference of the mounting sleeve 5, one end of the third limiting protrusion 53 is directly opposite to the second limiting protrusion 420 in the up-down direction, and the other end is staggered with the second limiting protrusion 420 in the up-down direction. Therefore, when the third limiting protrusion 53 of the mounting sleeve 5 begins to slide into the upper side surface of the second limiting rib 34 (at this time, it just slides in from the starting end of the second limiting rib 34), the second limiting protrusion 420 of the garbage disposer 4 has not yet contacted with the second limiting rib 34. When the positioning protrusion 53 completely slides onto the second positioning protrusion 34 (at this time, it is close to the middle of the second positioning protrusion 34), at this time, the second positioning protrusion 420 of the garbage disposer 4 just begins to contact the second positioning protrusion 34. When the downpipe 3 is rotated and installed, the lower side surface of the second positioning protrusion 34 of the downpipe 3 and the second positioning protrusion 420 of the garbage disposer 4 slide frictionally. Since the inclination angle of the lower side surface of the second positioning protrusion 34 relative to the horizontal plane is greater than the inclination angle of the upper side surface relative to the horizontal plane, the installation sleeve 5 and the upper cover body will be separated in the vertical direction during the frictional sliding. This structural design allows the second positioning protrusion 34 of the downpipe 3 to smoothly rotate and slide between the third positioning protrusion 53 of the installation sleeve 5 and the second positioning protrusion 420 of the upper cover body without shaking up and down.

[0047] The upper side surface of the second limiting rib 34 is also designed to be gradually inclined downward from the starting end to the end of the second limiting rib 34, which greatly facilitates the manual installation of the third limiting protrusion 53 of the installation sleeve 5, and can also effectively prevent the installation sleeve 5 from loosening, falling off, and falling back after the installation sleeve 5 is installed in place. The rear end of the second limiting rib 34 of the downpipe 3 is designed with a blocking structure 343 extending upward to indicate the limit position of the rotation and tightening of the third limiting protrusion 53 of the installation sleeve 5.

[0048] The number of the support frames 6 of this embodiment is consistent with the number of the through holes 510 of the mounting sleeve 5. Specifically, the main body of the support frame 6 is in the shape of a long strip and is inserted into the through holes 510 of the mounting sleeve 5. After the support frame 6 is installed in place in the mounting hole of the mounting sleeve 5, both ends of the support frame 6 are exposed from the through holes 510 of the mounting sleeve 5 and extend to the left and right for a distance respectively. The two ends of the support frame 6 are respectively recorded as the first end 61 and the second end 62. The upper and lower dimensions of the through holes 510 of the mounting sleeve 5 are slightly larger than the upper and lower dimensions of the main body of the support frame 6, thereby allowing the entire support frame 6 to swing up and down with the position of the through holes 510 of the mounting sleeve 5 as the fulcrum. The top of the garbage disposer 4 also has three first extension walls 41 extending upward, and the top side edge of the first extension wall 41 has a first limit stop 410 extending circumferentially toward the first end 61 of the support frame 6 and limiting the upward movement of the first end 61 above the first end 61 of the support frame 6. During the upward movement of the installation sleeve 5 relative to the garbage disposer 4, since the first limit stop 410 of the garbage disposer 4 is limited above the first end 61 of the support frame 6, the second end 62 of the support frame 6 will be tilted upward and directly or indirectly pressed upward against the bottom of the locking ring 2. Considering that there is a certain distance between the locking ring 2 and the support frame 6 in the up-down direction, and the swing range of the support frame 6 in the through hole 510 is limited, in order to enable the second end 62 of the support frame 6 to be firmly pressed against the bottom of the locking ring 2 even at a smaller swing angle, the second end 62 of the support frame 6 in this embodiment has a support rod 621 extending upward, and the top of the support rod 621 can be directly or indirectly pressed against the bottom of the locking ring 2.

[0049] The support outer frame 7 of this embodiment is an annular cover structure, and the support outer frame 7 is sleeved outside the mounting sleeve 5 and each support frame 6. The three first extension walls 41 of the garbage disposer 4 are also provided with a limit bayonet 411 that penetrates inside and outside and extends in the up-down direction. The first extension wall 41 is an arc-shaped plate, and the inner wall surface of the support outer frame 7 can fit with the outer wall surface of the first extension wall 41. The inner wall surface of the support outer frame 7 is also provided with three convex buckles 72 that protrude radially inward, and the convex buckles 72 can be snapped into the limit bayonet 411 of the first extension wall 41 and slide up and down in the bayonet, thereby realizing the upper and lower movement constraint between the support outer frame 7 and the garbage disposer 4. The top edge of the support outer frame 7 has a support stopper 71 that extends radially inward, and the bottom of the locking ring 2 has a positioning notch 24 that is recessed upward, and the above-mentioned support stopper 71 can be limited in the positioning notch 24. The top of the garbage disposer 4 also has an annular limiting slot 43, and the outer peripheral edge of the lower port of the supporting outer frame 7 can be inserted into the above-mentioned limiting slot 43, thereby realizing the limiting of the supporting outer frame 7 in the inner and outer directions.

[0050] Each support frame 6 of this embodiment is located below the support stop edge 71 of the support outer frame 7. The top of the support rod 621 of the second end 62 of each support frame 6 can abut against the bottom of the support stop edge 71, and drive the support outer frame 7 to move upward during the upward tilting process, so that the support stop edge 71 abuts against the bottom of the locking ring 2 upward, ensuring that the water tank 1 and the locking ring 2 can achieve a high sealing and waterproof effect. Since the locking ring 2 is pushed upward by the support outer frame 7, even during the vibration process of the garbage disposer 4, the locking ring 2 is not prone to reverse loosening.

[0051] The elastic member 63 of this embodiment is a spring. The spring is pressed between the second end 62 of the support frame 6 and the top of the garbage disposer 4. Specifically, the bottom of the second end 62 of the support frame 6 has a placement groove 622 for accommodating the upper end of the spring, and the top of the garbage disposer 4 has an extension rod 44 extending upward at a position corresponding to the position below the second end 62 of the support frame 6. The lower end of the spring is sleeved on the extension rod 44, so that the spring can be firmly arranged between the support frame 6 and the top of the garbage disposer 4. Under the elastic force of the spring, the installation sleeve 5 (the support frame 6 also drives the installation sleeve 5 to move upward) and the garbage disposer 4 keep away from each other, so that during the initial installation, the third limiting protrusion 53 of the installation sleeve 5 and the second limiting protrusion 420 of the garbage disposer 4 can easily slide into the upper and lower side surfaces of the second limiting rib 34.

[0052] The present embodiment also relates to a garbage disposal device, including a garbage disposal device 4 that can be installed under a sink 1 via a quick-release connection structure, and the quick-release connection structure adopts the quick-release connection structure between the garbage disposal device and the sink described above.

[0053] The installation process of the quick-release connection structure between the garbage disposer 4 and the water tank 1 of this embodiment is as follows:

[0054] First, the flexible sealing ring 11 is embedded in the periphery of the installation opening 10 of the water tank 1, and then the downpipe 3 passes through the flexible sealing ring 11, so that the annular flange 31 of the downpipe 3 presses the radial extension 111 of the flexible sealing ring 11 against the top of the outer peripheral edge of the installation opening 10 of the water tank 1, and then the locking ring 2 is screwed upward and pressed against the bottom of the outer peripheral edge of the installation opening 10 of the water tank 1, and finally the downpipe 3 is connected to the upper cover of the garbage disposer 4. When the garbage disposer 4 is installed with the downpipe 3, the operator can give the garbage disposer 4 an upward thrust. At this time, the third limiting protrusion 53 of the installation sleeve 5 is not hung on the second limiting rib 34 of the downpipe 3. The upward thrust of the operator gives a pressure to the support outer frame 7, causing the support outer frame 7 to drop, the support frame 6 to drop, and the spring to bear the pressure. The advantage of this design is that the third limiting protrusion 53 of the installation sleeve 5 can be more conveniently hung on the upper part of the second limiting rib 34 of the downpipe 3. Then, the third limiting protrusion 53 of the installation sleeve 5 and the second limiting protrusion 420 on the upper cover of the garbage disposer 4 are slidably matched on the upper and lower sides of the second limiting rib 34 of the downpipe 3 by rotating the operation again. After being installed in place, the garbage disposer 4 is in a suspended state. By using the lever principle, the gravity of the garbage disposer 4 is converted into an upward thrust of the locking ring 2, so that a reliable seal is achieved between the outer peripheral edge of the installation opening 10 of the water tank 1 and the annular flange 31 and the flexible sealing ring 11 of the downpipe 3. The greater the gravity of the garbage disposer 4, the greater the upward thrust, the better the sealing, and the less likely the locking ring 2 is to loosen. The self-locking component of this embodiment is an assembly of the garbage disposer 4 as a whole, which adopts a rotating installation method and uses the garbage disposer 4's own gravity to lock the water tank 1, the garbage disposer 4 and the downpipe 3.
