Description

Technical Field

[0001] The utility model relates to the technical field of kitchen waste disposers, in particular to an automatic rotating flip cover mechanism and a waste disposer having the same. Background Art

[0002] With technological advancements, people are paying more and more attention to waste disposal, and the treatment of food waste is particularly important. Because food waste contains a large amount of organic matter and is easily corrupted and odorous, various environmental problems may occur during the waste collection and disposal process. As a result, food waste disposers have emerged, and more and more people are using food waste disposers to deal with the food waste generated in their daily lives.

[0003] There are three common flip-top solutions for food waste disposers on the market:

[0004] 1) Using a flip-up motor to rotate the lid. This solution has the advantages of convenience and touchless operation, but also has obvious disadvantages: high cost, high noise, and easy motor damage.

[0005] 2) A long-arm torsion spring is provided to drive the lid's rotation. This solution has the advantages of a simple structure and relatively low cost. However, its disadvantages are also significant. Due to the long torsion spring arm, the spring is prone to deformation and failure. Furthermore, to prevent the spring from being exposed, a cover is often required to cover the long torsion spring arm, which increases costs and detracts from the design.

[0006] 3) Manual flip cover: This design is the most common flip cover solution. Its advantages are simple structure and low cost. However, its disadvantage is that the cover needs to be opened manually to the appropriate angle.

[0007] Based on this, there is an urgent need in the prior art to design a flip cover mechanism that does not require manual flipping, is easy to operate and is not easily damaged, and a garbage disposer having the same. Utility Model Content

[0018] In the technical solution of this embodiment, the automatic rotating flip cover mechanism also includes a pressure plate and a pressure plate spring. The pressure plate is fixedly mounted on the support cover. The pressure plate includes a deformation portion. The two ends of the pressure plate spring are respectively connected to the locking member and the deformation portion.

[0019] Furthermore, the automatic rotating flip cover mechanism also includes a button, which is arranged on the support cover in a liftable manner and is arranged above the deformation part. When the button is lowered, it can press the deformation part and cause it to deform.

[0020] Furthermore, the automatic rotating flip cover mechanism further includes a key spring, which is arranged between the key and the support cover, and is used to provide a force for the key to move away from the support cover.

[0021] Furthermore, the middle frame is provided with a through hole, and the position of the through hole corresponds to the position of the button.

[0041] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0042] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0044] See also Figure 1 and Figure 3 As shown, according to an embodiment of the present invention, the automatic rotating flip cover mechanism 1 includes a support cover 2, a middle frame 4 and a top cover 5. The middle frame 4 is fixedly mounted on the support cover 2. The middle frame 4 is an annular structure with an opening in the middle. The top cover 5 is located at the opening. The middle frame 4 is provided with a shaft sleeve 41, and the shaft sleeve 41 is preferably arranged at the bottom position of the middle frame 4. The top cover 5 is provided with a rotating shaft 52, and the rotating shaft 52 is inserted into the shaft sleeve 41 so that the top cover 5 and the middle frame 4 can be rotatably connected together. When the top cover 5 is flipped upward relative to the middle frame 4 to open, the middle opening of the middle frame 4 is the opening of the garbage disposer for users to put garbage. When the top cover 5 is flipped down to close, the top cover 5 blocks the middle opening of the middle frame 4. At this time, the garbage disposer is in a closed state and garbage cannot be put in.

[0045] See also Figure 4 As shown, the support cover 2 is provided with a locking member 31, which includes a snap portion 311. A slot 51 is provided on the side of the top cover 5, preferably located at the front end of the top cover 5. When the top cover 5 is closed, the snap portion 311 of the locking member 31 extends into the slot 51, thereby locking the top cover 5 and preventing it from flipping upward. When the snap portion 311 of the locking member 31 is released from the slot 51, the top cover 5 flips upward under the driving force of the elastic member 6, achieving an automatic flipping effect for the top cover 5. The structural design is simple and rational, and the operation is easy.

[0046] See also Figure 1 and Figure 2As shown, the automatic rotating flip cover mechanism 1 further includes an elastic member 6, which includes a main body 61 and an abutment portion 62 extending outward from the main body 61. The main body 61 is disposed around the rotating shaft 52 and is fixedly connected to the rotating shaft 52. The abutment portion 62 abuts the middle frame 4. Specifically, because the elastic member 6 is made of an elastic material, when the top cover 5 is in the closed state, the abutment portion 62 abuts the middle frame 4, and the elastic member 6 is in a compressed state as a whole. As a result, the main body 61 applies a force to the rotating shaft 52 in a direction away from the support cover 2. Therefore, through the above structural design, the elastic member 6 can provide the force for the top cover 5 to flip upward and open. In particular, since the force exerted by the elastic member 6 on the rotating shaft 52 is applied at the main body 61 disposed around the rotating shaft 52, and the abutment portion 62 only provides the force to compress the elastic member 6 as a whole, its length does not need to be long; it only needs to be able to abut the support cover 2. Therefore, compared with the long-arm torsion spring and other structures in the prior art, the structure of the rotating shaft 52, elastic member 6 and other structures of the present invention that realize the automatic flipping of the top cover 5 are not prone to deformation, failure and damage, and the structural design is simple, which can significantly reduce costs.

[0047] Preferably, see Figure 1 and Figure 3 As shown, the automatic rotating flip cover mechanism 1 also includes a Hall switch 21 and a PCB board 22. Both the Hall switch 21 and the PCB board 22 are disposed on the support cover 2. A light guide 221 is disposed on the PCB board 22. The middle frame 4 is provided with a panel, and the position of the panel corresponds to the position of the light guide 221. Specifically, the Hall switch 21 is provided to realize the automatic opening and closing function of the top cover 5. When a hand approaches the garbage disposal, the Hall switch 21 senses the change in the magnetic field and notifies the garbage disposal control system via a signal, realizing the automatic opening of the top cover 5. When the hand leaves the garbage disposal, the top cover 5 automatically closes. The provision of the light guide 221 transmits the LED light on the PCB board 22 to the panel of the middle frame 4, which is used to display relevant status or indications.

[0048] In particular, the number of PCB boards 22 can be set to two, one of which is a power PCB board and the other is a dehumidification PCB board; accordingly, the number of light guides 221 is also set to two, and corresponds to the positions of the power PCB board and the dehumidification PCB board.

[0049] Example 1

[0050] In a preferred embodiment of the present invention, a specific structural design scheme for the rotating shaft 52 and the elastic member 6 is provided.

[0051] See also Figure 2As shown, in the technical solution of this embodiment, the rotating shaft 52 is provided with a groove 521, and the elastic member 6 also includes a fixing portion 63 formed by the inward extension of the main body 61. The fixing portion 63 is fixed in the groove 521 to fix the main body 61 and the rotating shaft 52. Among them, the groove 521 has an opening, and the opening is located at the end of the rotating shaft 52. During installation, the fixing portion 63 of the elastic member 6 is aligned with the opening and the main body 61 is inserted into the rotating shaft 52, which is simple to operate. Specifically, after the fixing portion 63 is inserted into the groove 521, the main body 61 and the rotating shaft 52 are fixedly connected, so that the elastic member 6 provides the force for the top cover 5 to flip upward and open.

[0052] See also Figure 1 As shown, in a preferred embodiment, there are two rotating shafts 52 and two elastic members 6, and one elastic member 6 is disposed correspondingly to one rotating shaft 52, and the other elastic member 6 is disposed correspondingly to the other rotating shaft 52. More specifically, the two rotating shafts 52 are symmetrically disposed, and the two elastic members 6 are also symmetrically disposed accordingly.

[0053] See also Figure 2 As shown, in another preferred embodiment of the present invention, the elastic member 6 can be a torsion spring. In this case, the main body 61 of the elastic member 6 is the spring body of the torsion spring, which is sleeved on the outer circumference of the rotating shaft 52; the abutment portion 62 of the elastic member 6 is the torsion arm of the torsion spring, which extends from the spring body and abuts against the support cover 2.

[0054] Example 2

[0055] In another preferred embodiment of the present invention, a specific structural design scheme is provided on how to realize automatic flipping of the top cover 5 .

[0056] See also Figure 3 and Figure 4 As shown, in the technical solution of this embodiment, the automatic rotating flip cover mechanism 1 also includes a pressure plate 32 and a pressure plate spring 33. The pressure plate 32 is fixedly mounted on the support cover 2 and includes a deformed portion 321. The front and rear ends of the pressure plate spring 33 are connected to the locking member 31 and the deformed portion 321, respectively. The deformed portion 321 of the pressure plate 32 can elastically deform under external pressure, thereby driving the locking member 31 backward through the pressure plate spring 33. When the locking portion 311 of the locking member 31 leaves the locking slot 51, the top cover 5 is driven upward by the driving force of the elastic member 6, achieving the automatic flipping effect of the top cover 5. The structural design is simple and reasonable, and the operation is easy. When the external pressure disappears, the deformed portion 321 of the pressure plate 32 returns to its original shape, and the locking portion 311 of the locking member 31 re-enters the locking slot 51, locking the top cover 5 and preventing it from flipping open.

[0057] See also Figure 3 and Figure 4As shown, in a preferred embodiment of this embodiment, the automatic rotating flip cover mechanism 1 further includes a button 7, which is movably mounted on the support cover 2 and positioned above the deformed portion 321 of the pressure plate 32. When the button 7 descends, it presses the deformed portion 321, causing it to deform. The button 7 is configured to be pressed downward by a user. When the button 7 descends a certain distance, it contacts the deformed portion 321 of the pressure plate 32 and elastically deforms downward through the pressure force. This, in turn, drives the latch 31 backward via the pressure plate spring 33. When the latch portion 311 of the latch 31 exits the slot 51, the top cover 5 flips upward under the driving force of the elastic member 6, achieving the automatic flipping effect of the top cover 5. When the button 7 is released, it ascends, causing the deformed portion 321 of the pressure plate 32 to return to its original shape. At this point, the latch portion 311 of the latch 31 reenters the slot 51, locking the top cover 5 and preventing it from flipping open.

[0058] Further, see Figure 3 As shown, the automatic rotating flip cover mechanism 1 further includes a button spring 71, which is disposed between the button 7 and the support cover 2. The button spring 71 is used to provide a force for the button 7 to move away from the support cover 2. Specifically, when the button 7 is in the initial state (i.e., not pressed), the elastic force of the button spring 71 prevents the button 7 from contacting the deformed portion 321 of the pressure plate 32. At this time, the locking portion 311 of the locking member 31 is located in the locking slot 51 of the top cover 5. The top cover 5 cannot be opened due to the locking action of the locking member 31.

[0059] See also Figure 2 and Figure 3 As shown, in another preferred embodiment of the present invention, the middle frame 4 is provided with a through hole 42, which corresponds to the position of the button 7, so that the button 7 provided on the support cover 2 extends from the middle frame 4, making it easier for the user to press the button 7. More specifically, when the button 7 is in the initial state (i.e., not pressed), the top of the button 7 is flush with the middle frame 4, improving the overall aesthetics of the flip cover mechanism.

[0060] Example 3

[0061] Based on the same design concept, the present invention also provides a specific embodiment of a garbage disposer. In the technical solution of this embodiment, the garbage disposer includes a barrel 8 and the automatic rotating flip cover mechanism 1 described in the above embodiment.

[0062] See also Figure 5As shown, the automatic rotating flip cover mechanism 1 is located at the top of the barrel body 8, and a storage chamber for accommodating kitchen waste is formed between the automatic rotating flip cover mechanism 1 and the barrel body 8. Specifically, the support cover 2 of the automatic rotating flip cover mechanism 1 is fixedly mounted at the top opening of the barrel body 8, and the middle frame 4 is fixedly mounted on the support cover 2. The opening in the middle of the middle frame 4 is the opening of the garbage disposer. When the top cover 5 is flipped upward to open, the user can place garbage. When the top cover 5 is flipped downward to close, the top cover 5 blocks the middle opening of the middle frame 4, and the garbage disposer is now in the closed state.

[0063] Furthermore, a first sealing ring (not shown) is provided between the support cover 2 and the barrel body 8, and a second sealing ring 23 is provided between the support cover 2 and the top cover 5. The main purpose of providing the first sealing ring is to improve the sealing performance between the support cover 2 and the barrel body 8, and the main purpose of providing the second sealing ring is to improve the sealing performance between the support cover 2 and the top cover 5, thereby preventing external pollutants such as dust, sand, and water from entering the interior of the garbage disposer, and preventing garbage or odor from leaking out of the garbage disposer, which would affect the user experience.

[0064] The technical means disclosed in the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
