Especially during the food waste disposer's processing of food waste, if the lid is opened due to human error or children, it will pose a certain safety hazard. Utility Model Content
[0003] To address the aforementioned problems, this invention provides a double lock and a food waste processor.
[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows:
[0005] A double lock includes a housing, a button, a latch, a first locking element, and a second locking element. The latch is pivotally connected to the housing and has two opposing swing directions, a first direction and a second direction. The button can be applied force and moved toward the latch to drive the latch to move along the first direction to unlock.

Detailed Implementation
[0026] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.
[0027] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0028] Reference Figure 1-9 This embodiment provides a food waste disposer, including a container body 1, a flip-top lid 2, and a double lock. The flip-top lid 2 is installed on the container body 1, and the double lock is installed inside the container body 1 to control the locking or unlocking of the flip-top lid 2.
[0029] Reference Figure 2 The double lock includes a housing 3, a button 4, a latch 5, a first locking element, and a second locking element. The latch 5 is pivotally connected to the housing 3, and a snap-fit part is provided inside the flip cover 2 for the latch 5 to be locked in place by flipping it over. Figure 3 As shown, the latch 5 has two opposing swing directions, a first direction and a second direction. The latch 5 is defined to unlock by swinging along the first direction and lock by swinging along the second direction. The button 4 can be applied with an external force and moved toward the latch 5 to drive the latch 5 to move along the first direction to unlock. The first locking member is elastic and configured such that: after the latch 5 is unlocked by swinging along the first direction when pressed by the button 4, the first locking member stores energy and releases energy after the external force is removed from the button 4 to drive the latch 5 to swing along the second direction to lock. The second locking member can prevent the latch 5 from swinging along the first direction, preventing the button 4 from moving toward the latch 5; or it can release the restriction on the latch 5's swing along the first direction, allowing the button 4 to be applied with an external force and move toward the latch 5 to unlock.
[0030] By setting the first and second locking components, a double locking mechanism can be achieved. That is, when the flip cover 2 does not need to be opened, the second locking component further restricts the swing of the hook 5, and the button 4 cannot be pressed to unlock the hook 5. This prevents the flip cover 2 from being opened by human error or by children, thus avoiding safety hazards when the food waste processor is processing food waste.
[0031] The first locking element includes a return spring 6, which is disposed within the housing 3 and abuts against the latch 5. The return spring 6 is configured such that when the latch 5 swings in a first direction to unlock, the return spring 6 is in a stored state; when the return spring 6 is in a released state, it can drive the latch 5 to swing in a second direction to lock. In other embodiments, the return spring 6 can also be other elastic elements, such as a gas spring; however, compared to gas springs, gas springs occupy more space, making the double-lock structure design more complex and costly.
[0032] Furthermore, to ensure stability when the flip cover 2 is closed, two or more hooks 5 are arranged side by side. An abutment plate 31 is pivotally connected inside the housing 3. The swing axis of the abutment plate 31 is parallel to the swing axis of the hooks 5, and the abutment plate 31 can contact all hooks 5. The button 4 can be pressed by external force, which is transmitted to the hooks 5 through the abutment plate 31. In this embodiment, two hooks 5 are arranged at intervals, and a return spring 6 corresponds to each hook 5. By pressing the button 4, the abutment plate 31 swings towards the two hooks 5, thereby causing the two hooks 5 to swing.
[0033] The second locking element includes a blocking piece 7 and a driving part. The driving part drives the blocking piece 7 so that the blocking piece 7 can enter or exit the path of the button 4 moving towards the hook 5 under external force, thereby restricting the hook 5 from swinging in the first direction or releasing the restriction on the hook 5 swinging in the first direction. When the blocking piece 7 is in the path, it restricts the button 4 from applying force to the hook 5, so that the hook 5 cannot swing in the first direction under the pressure of the button 4 and cannot be unlocked; when the blocking piece 7 exits the path, it releases the restriction on the button 4, the button 4 can be pressed, so that the hook 5 can swing in the first direction and unlock. In other embodiments, the blocking piece 7 can also be configured to block the hook 5 from swinging in the first direction, for directly blocking the hook 5 from swinging in the first direction.
[0034] Specifically, the blocking piece 7 is slidably arranged in the housing 3 along a straight line. In other embodiments, the blocking piece 7 can also be moved into or out of the button 4 toward the hook 5 by means of eccentric rotation, but the structure design of the eccentric rotation method is more complicated and the stability of the blocking piece 7 is poor.
[0035] Furthermore, such as Figure 4 and Figure 5The blocking plate 7 is provided with a toothed groove portion 71, and the driving part includes a gear 9 and a drive motor 8. The drive motor 8 is mounted on the housing 3, and a motor cover 32 is provided on the housing 3 to facilitate the installation and stability of the drive motor 8. The output end of the drive motor 8 is connected to the gear 9 for transmission. The gear 9 meshes with the toothed groove portion 71. The drive motor 8 drives the gear 9 to rotate forward or backward, thereby driving the blocking plate 7 to perform reciprocating linear motion. To ensure that the blocking plate 7 can slide smoothly, a strip-shaped guide hole 72 is provided on the blocking plate 7, and the length direction of the guide hole 72 is the moving direction of the blocking plate 7. A guide rod 33 is provided inside the housing 3, and the guide rod 33 is inserted into the guide hole 72, and the two can slide relative to each other. In this embodiment, two sets of guide holes 72 are provided and arranged on both sides of the gear 9. The guide rod 33 inside the housing 3 corresponds one-to-one with the guide hole 72. Through the two sets of guide holes 72 and guide rods 33, the smoothness and stability of the movement of the blocking plate 7 are further ensured. Specifically, the blocking plate 7 has a clearance notch on the side near the gear 9, making the blocking plate 7 have a U-shaped structure. The blocking plate 7 will not interfere with the gear 9 during movement. The tooth groove 71 is located on one inner side of the clearance notch, and the guide holes 72 are arranged on both sides of the blocking plate 7. In this way, space can be used reasonably, making the structure compact and stable.
[0036] Furthermore, such as Figure 4-9 Inside the housing 3, a first microswitch 34 and a second microswitch 35 are arranged at intervals along the sliding direction of the blocking plate 7 to sense the movement stroke of the blocking plate 7. A protrusion 73 is provided on the blocking plate 7. The protrusion 73 is configured such that: when the protrusion 73 abuts against the first microswitch 34, it blocks the path of the release button 4 moving toward the hook 5 under external force, releasing the restriction on the button 4, allowing the button 4 to be pressed to apply force to the hook 5, thereby releasing the restriction on the hook 5 to swing in the first direction; when the protrusion 73 abuts against the second microswitch 35, the blocking plate 7 enters the path of the button 4 moving toward the hook 5 under external force, restricting the button 4 so that it cannot move toward the hook 5 under external force, thereby restricting the hook 5 to swing in the first direction.
[0037] In this embodiment, the food waste processor includes a control module that controls the operation of the entire device. The first microswitch 34 and the second microswitch 35 are electrically connected to the control module within the food waste processor to control the operation of the drive motor 8. When unlocking, for example when no food waste has been processed in the bin 1, the control module sends a command to the drive motor 8. The drive motor 8 rotates, causing the blocking plate 7 to descend via the gear 9, separating the protrusion 73 from the second microswitch 35. When the protrusion 73 contacts the first microswitch 34, the button 4 moves towards the latch 5 under external force, thereby unlocking the latch 5. The first microswitch 34 then sends a signal to the control module, which in turn sends a command to the drive motor 8, ordering the drive motor 8 to stop rotating. Similarly, when locking is required, for example, when food waste needs to be disposed of in the bin 1, the control module sends a command to the drive motor 8, the drive motor 8 reverses, causing the blocking plate 7 to rise, so that the protrusion 73 separates from the first micro switch 34. When the protrusion 73 contacts the second micro switch 35, the button 4 is restricted and cannot move toward the hook 5 under external force, that is, the hook 5 is in a locked state. In addition, the second micro switch 35 sends a signal to the control module, and the control module sends a command to the drive motor 8, ordering the drive motor 8 to stop rotating.
[0038] The double lock also includes a sensing device 10, which in this embodiment is a PCB sensing circuit board. The sensing device 10 is disposed inside the housing 3, and a touch spring 11 is connected to the sensing device 10. The other end of the touch spring 11 is connected to the button 4. In this embodiment, the button 4 can be a capacitive touch button, electrically connected to the sensing device 10 via the touch spring 11. The sensing device 10 is configured to emit a reminder signal when the second locking member restricts the hook 5 from swinging in a first direction, and the button 4 is pressed. For example, the sensing device 10 can be configured to connect to an indicator light, which reminds the user that the button 4 can only be pressed to open the flip cover 2 when the second locking member releases the restriction on the hook 5.
[0039] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
