Description

Technical Field

[0001] This utility model relates to the field of waste treatment technology, and more specifically to a double safety lock structure for a kitchen waste processor and a kitchen waste processor. Background Technology

[0002] With the increasing emphasis on green and low-carbon lifestyles and the growing public awareness of environmental protection, consumers are seeking more environmentally friendly and efficient kitchen waste disposal solutions, making food waste disposers a standard feature of quality living. Among these, food waste disposers that grind, mix, and dry waste simply require pouring wet food waste into the machine's bin; the waste is automatically mixed, dried, and ultimately becomes dry compost. However, during operation, the inner bin of a food waste disposer reaches high temperatures. Currently available food waste disposers on the market, such as the one disclosed in Chinese patent CN212189390U, all use a single button or switch to open the lid, lacking a child lock safety feature. If a child opens the lid while the machine is operating, they are easily burned by the hot inner bin components, resulting in poor safety. Utility Model Content

[0035] Reference Figure 1-7 This invention describes a dual-safety-lock structure for a food waste disposer according to an embodiment of the present invention, and the food waste disposer thereof.

[0036] In one embodiment, such as Figure 1-7 As shown, a dual-safety-lock structure for a food waste disposer includes a mechanical lock assembly and an electronic lock assembly.

[0037] The mechanical lock assembly includes a mechanical lock button 1 and a rotating arm 2. The mechanical lock button 1 is provided with a protrusion 11, which is used to push one end of the rotating arm 2 to rotate. The other end of the rotating arm 2 cooperates with the cover plate 3 of the food waste disposer to realize the opening and closing of the cover plate 3. The cover plate 3 is connected to the food waste disposer through a cover plate torsion spring 32.

[0038] The electronic lock assembly includes an electronic control button 4, a lock cylinder lifting mechanism, and a lock cylinder slider 5. The lock cylinder slider 5 is located between the mechanical lock button 1 and the rotating arm 2, and the lock cylinder slider 5 has an opening 51 for the protrusion 11 to pass through. The electronic control button 4 is electrically connected to the lock cylinder lifting mechanism, which drives the lock cylinder slider 5 to move up and down. The mechanical lock button 1 can be pressed when and only when the opening 51 is aligned with the protrusion 11, and the protrusion 11 passes through the opening 51 to push the rotating arm 2 to unlock.

[0039] In practice, when the food waste disposer finishes working or is powered off, the electronic lock component unlocks, the lock cylinder slider 5 moves up, so that the protrusion 11 of the mechanical lock button 1 faces the opening 51 of the lock cylinder slider 5, and the mechanical lock button 1 can be pressed, the cover 3 opens, and the double safety lock unlocking function is completed.

[0040] When the food waste disposer is powered on or working, the electronic lock assembly automatically locks, and the lock cylinder slider 5 moves down, causing the opening 51 to be misaligned with the protrusion 11 of the mechanical lock button 1. At this time, the mechanical lock button 1 is blocked and the user cannot press it, thus completing the double safety lock locking function.

[0041] When the food waste disposer finishes working and the cover 3 needs to be opened, the cover 3 is equipped with an electronic control button 4. After pressing the electronic control button 4, the mechanical lock button 1 can be pressed to open the cover 3.

[0042] In one embodiment of this invention, the other end of the rotating arm 2 is provided with a protrusion 21, which cooperates with a recess 31 on the cover plate 3 of the food waste disposer to enable opening and closing of the cover plate 3. The other end of the rotating arm 2 can also cooperate with the cover plate 3 of the food waste disposer in other ways, such as by providing a protrusion on the cover plate 3 and a corresponding recess on the other end of the rotating arm 2, or other commonly used mating structures in the prior art.

[0043] This embodiment provides a dual-safety-lock structure for a food waste disposer. The mechanical lock button 1 can only be pressed to open the cover 3 when the electronic lock is open. By combining the electronic lock and the mechanical lock, dual-safety-lock protection is achieved, resulting in better security.

[0044] In this embodiment, the lock cylinder lifting mechanism includes a motor speed-changing gearbox 6, which is electrically connected to the electronic control button 4. A gear edge is provided on the side of the lock cylinder slider 5 near the motor speed-changing gearbox 6, and this gear edge meshes with the gears of the motor speed-changing gearbox 6, causing the lock cylinder slider 5 to move up and down as the gears rotate. The above embodiment utilizes the gear meshing structure between the motor speed-changing gearbox 6 and the lock cylinder slider 5 to achieve the up and down movement of the lock cylinder slider 5, resulting in a simple structure and convenient control.

[0045] In this embodiment, the lock cylinder lifting mechanism also includes a first limit switch 61 and a second limit switch 62. Both the first limit switch 61 and the second limit switch 62 are electrically connected to the electronic control button 4. The first limit switch 61 and the second limit switch 62 are respectively located at the upper and lower limit positions of the movement path of the lock cylinder slider 5, which can limit the up and down movement of the lock cylinder slider 5.

[0046] The first limit switch 61 and the second limit switch 62 can be mechanical limit switches or non-contact limit switches, and this embodiment does not limit them.

[0047] In this embodiment, the motor speed change gearbox 6, the first limit switch 61 and the second limit switch are fixedly mounted on the bracket 7, and the lock cylinder slider 5 is mounted on the bracket 7 so as to move up and down.

[0048] The first limit switch 61 and the second limit switch are fixedly installed on the upper and lower parts of the bracket 7, respectively; the motor speed change gearbox 6 is fixedly installed on the middle part of the side of the bracket 7; the lock cylinder slider 5 can be installed on the bracket 7 by moving it up and down through a slide groove, a limiting hole, or other structure. In the above embodiment, the bracket 7 is used to install the lock cylinder slider 5, the motor speed change gearbox 6, the first limit switch 61, and the second limit switch, integrating these components onto the bracket 7 for easy overall installation and disassembly.

[0049] In this embodiment, the bracket 7 is provided with at least two limiting rods, and the lock cylinder slider 5 is provided with at least two elongated limiting through holes. The limiting rods pass through the limiting through holes, and the lock cylinder slider 5 is installed on the bracket 7 by screws. In the above embodiment, the lock cylinder slider 5 can move up and down relative to the bracket 7 through the cooperation of the limiting through holes and the limiting rods of the bracket 7. The structure is simple, the assembly is convenient, and it helps to reduce costs.

[0050] In this embodiment, a reset button spring 12 is sleeved on the mechanical lock button 1, and the mechanical lock button 1 and the button spring 12 are disposed on the front cover 8 of the food waste disposer. Specifically, the mechanical lock button 1 and the button spring 12 are fastened together on the front cover 8 of the food waste disposer; the front cover 8 has a groove for installing the mechanical lock button 1, and the mechanical lock button 1 and the button spring 12 are installed in the groove. The button spring 12 is sleeved on the mechanical lock button 1, serving a reset function.

[0051] In this embodiment, the rotating arm 2 is mounted on the rotating pivot shaft 23 via a torsion spring 22. The rotating pivot shaft 23 is located on the main frame 9 of the food waste disposer. The rotating arm 2 rotates around the rotating pivot shaft 23. When one end of the rotating arm 2 is pressed down, the protrusion 21 at the other end disengages from the recess 31 of the cover plate 3, and the cover plate 3 opens under the action of the cover plate torsion spring 32, thus unlocking and opening the cover plate 3. The mechanical lock button 1 resets under the action of the button spring 12, and the rotating arm 2 also automatically resets under the action of the torsion spring 22.

[0052] In the above embodiments, the rotating arm 2 is installed by a torsion spring 22, which can automatically reset the rotating arm 2 when it loses external thrust; and the rotation fulcrum shaft 23 is set on the main frame 9, which has good structural stability and is easy to assemble.

[0053] In this embodiment, the bracket 7 is installed on the front cover 8 of the food waste disposer, and the front cover 8 is installed on the main frame 9 of the food waste disposer.

[0054] In specific implementation, the mechanical lock button 1 and button spring 12 are fastened together and installed on the front cover 8; the motor speed transmission gearbox 6, the first limit switch 61 and the second limit switch 62, and the lock cylinder slider 5 are respectively fixed on the bracket 7, and then the whole assembly is installed on the front cover 8 via the bracket 7, completing the assembly of the front cover assembly; the rotating arm 2 and the torsion spring 22 are fixed on the main frame 9 via the rotating fulcrum shaft 23; then the front shell assembly is installed on the main frame 9, completing the assembly of the front shell assembly and the double safety lock structure. In the above embodiment, the bracket 7 is installed on the front cover 8, and the front cover 8 is installed on the main frame 9, which facilitates assembly.

[0055] In this embodiment, the electronic control button 4 is a mechanical button or a touch button. The electronic control button 4 is located on the cover plate 3 and is not on the same surface as the mechanical lock button 1, so that the user must press the button on a different surface to unlock the cover, which better prevents accidental opening and improves security.

[0056] The electronic control button 4 is located on the cover plate 3 or other locations on the food waste disposer, such as the front cover 8, the side, or the back. Preferably, the electronic control button 4 is located on the cover plate 3 and is not on the same surface as the mechanical lock button 1, so that the user must press the button to unlock the cover from different surfaces, which better prevents accidental opening of the cover and improves security.

[0057] Based on the above embodiments, the working principle of the dual safety lock structure of the food waste disposer is as follows:

[0058] Dual security lock unlocking function: such as Figures 2 to 4As indicated by the middle arrow, when the food waste disposer finishes its work or is turned off, the gears on the motor speed transmission gearbox 6 drive the lock cylinder slider 5 upward, triggering the first limit switch 61. The motor speed transmission gearbox 6 then stops working, completing the automatic unlocking of the electronic lock assembly. In this state, the protrusion 11 on the mechanical lock button 1 faces the opening 51 on the lock cylinder slider 5. Pressing the mechanical lock button 1 pushes the rotating arm 2 to rotate on the rotating fulcrum shaft 23, causing the protrusion 21 on the rotating arm 2 to disengage from the recess 31 on the cover plate 3. Under the force of the cover plate torsion spring 32, the cover plate 3 opens, completing the double safety lock unlocking function.

[0059] Dual safety lock function: such as Figures 5 to 7 As shown, when the cover 3 is closed, the rotating arm 2, under the force of the torsion spring 22, has its protrusion 11 engage with the recess 31 of the cover 3, and the rotating arm 2 and protrusion 11 reset. The mechanical lock button 1 resets under the force of the button spring 12, completing the closing action of the cover 3. When the food waste disposer is powered on or working, the gear on the motor speed gearbox 6 drives the lock cylinder slider 5 to move downward until the second limit switch 62 is triggered, and the motor speed gearbox 6 stops working. In this state, the opening 51 on the lock cylinder slider 5 deviates from the protrusion 11 on the mechanical lock button 1, and the mechanical lock button 1 is blocked and cannot be pressed, completing the locking of the electric lock assembly, thereby realizing the double safety lock locking function.

[0060] When the food waste disposer is working and the cover 3 needs to be opened, the cover 3 is equipped with an electronic control button 4, which can be a mechanical button or a touch button. When the electronic control button 4 is pressed, the gear on the motor speed gearbox 6 drives the lock cylinder slider 5 to move upward, triggering the first limit switch 61. The motor speed gearbox 6 stops working. In this state, the protrusion 11 on the mechanical lock button 1 faces the opening 51 on the lock cylinder slider 5. The mechanical lock button 1 can be pressed to push the rotating arm 2 to rotate on the rotating fulcrum shaft 23, so that the protrusion 21 at the upper end of the rotating arm 2 disengages from the recess 31 on the cover 3. Under the action of the cover torsion spring 32, the cover 3 opens.

[0061] In another embodiment, the present invention provides a food waste disposer that includes a dual safety lock structure as described in any of the above embodiments, which combines an electronic lock with a mechanical lock to achieve dual safety lock protection and improve security.
