Description

Technical Field

[0001] The utility model belongs to the technical field of trash cans, and particularly relates to a flexible belt bag collecting mechanism for trash cans. Background Art

[0002] Traditional trash cans generally use manual bagging, requiring users to manually close the trash bags, a cumbersome and unhygienic process. With the advancement of technology, smart trash cans have gradually entered the market. However, most existing smart trash cans suffer from complex structures, high energy consumption, and low bagging success rates. In particular, the bag opening is prone to getting stuck or not closing tightly, significantly impacting the user experience.

[0003] In order to improve the level of automation in garbage disposal, trash cans that can automatically pack garbage bags have gradually appeared on the market. These trash cans usually use one or two pressure rods / pressing plates to press the garbage bag's closing edge to the edge of the can, and then the sealing device cooperates with the pressure rod / pressing plate to complete the sealing and packing. For example, in the prior art, the Chinese patent with publication number CN106564717B discloses a device and method for automatically heat-sealing garbage bags in a trash can. This prior art includes a slider, a clamping plate, a heating module, a driving mechanism for driving the clamping plate to move toward the heating module, and a frame arranged on the mouth of the trash can. The heating module is fixed on the frame, and guide rails are provided on both sides of the frame. There are two sliders, which respectively cooperate with the guide rails on both sides of the frame. The clamping plate is installed on the two sliders. A bag opening placement area is formed between the clamping plate and the heating module. The bag opening placement area is located on the mouth of the trash can. When the clamping plate contacts the heating module, the opening of the garbage bag is closed. At this time, the heating module is started to melt the opening of the garbage bag, so that this existing technology can accurately and efficiently pack the garbage bag full of garbage.

[0004] However, in practical applications, the above-mentioned prior art still has the following defects:

[0005] (1) The device structure is complex and requires additional components such as sliders, guide rails, clamping plates, and synchronous pulleys. The control is cumbersome and the manufacturing cost is high.

[0006] (2) The clamping plate and the heating module are both made of rigid materials, and the contact area between them is large. Although this helps to improve the sealing efficiency, it can also easily cause the garbage bags to be damaged due to excessive heating, affecting the packaging effect and subsequent processing;

[0007] (3) Since the garbage bag is made of thin material, it is easy to get stuck on the corners of the pressure plate or pressure rod, making it impossible to close the bag, or even directly damaging the garbage bag, which reduces the user experience;

[0008] (4) The main structure of most pressing plates / pressing rods is long and narrow, and the side of these pressing plates / pressing rods that contacts the heating module is a flat structure. Once the pressing plates / pressing rods are bent, the flat structure will be deformed. This deformation will cause the garbage bag to be unable to fully contact the heating module after being pressed, thereby causing the garbage bag to be poorly sealed. This not only affects the sealing effect, but also reduces the reliability of packaging and the actual use effect.

[0009] Therefore, there is an urgent need for a flexible belt bag collecting mechanism for a trash can to solve the above problems. Summary of the Invention

[0058] like Figure 1-13 As shown, this embodiment provides a flexible belt bag collecting mechanism for a trash can, comprising a bag collecting body 4 disposed at the opening of the trash can, wherein a trash inlet 41 is provided in the middle of the bag collecting body 4; a cavity 44 is formed inside the bag collecting body 4, and the cavity 44 is an annular structure disposed around the trash inlet 41; a lateral opening is formed inside the cavity 44 and communicates with the trash inlet 41;

[0059] The bag receiving body 4 also includes a fuse 3, a limit block 5, a flexible belt 6 and a reel 7 arranged in the cavity 44; the fuse 3 includes a first arm 1 and a second arm 2, the first arm 1 having one end as the axis, and the other end driving the entire first arm 1 to rotate open or clamp relative to the second arm 2; the reel 7 is arranged on the side where the second arm 2 is located; the flexible belt 6 is transmission-connected to the reel 7, and the reel 7 rotates and drives the flexible belt 6 to elastically reel or unfold; the flexible belt 6 extends from the reel 7, passes through the limit block 5 and continues to extend along the lateral opening to connect with the first arm 1;

[0060] In this embodiment, the flexible belt 6 is automatically wound and unwound by the winding wheel 7, which greatly simplifies the process of sealing the garbage bag. The user does not need to manually close and tie the bag, which improves the convenience and efficiency of using the garbage bin and helps prevent the spread of odor from the garbage.

[0061] It should be noted that, during the retraction process, the length of the flexible belt 6 in the garbage inlet is continuously reduced under the drive of the reeling wheel 7, thereby retracting the garbage bag into the melting area of the fuse 3; and during the resetting process, the reeling wheel 7 releases the length of the flexible belt 6 within the garbage inlet 41. Under the elastic action of the flexible belt 6 itself and the drive of the reeling wheel 7, the flexible belt 6 is fully unfolded and adheres to the inner wall of the garbage bin head; this can maintain the appearance and save a lot of linkage mechanisms. Therefore, compared with other prior art packaging mechanisms, the flexible belt bag collecting mechanism of this embodiment has fewer power sources and a simpler overall structure.

[0062] Moreover, compared with the sealing structure of the pressure rod / pressure plate of the existing trash can, the structure of this embodiment is simpler. By designing the clamping mechanism of the first arm 1 and the second arm 2, this embodiment enables the fuse 3 to have a clamping function similar to that of a clip, which can effectively further clamp and collect the trash bag.

[0063] In addition, the bag receiving body 4 described in this embodiment is cleverly arranged at the mouth of the barrel, so that the bag receiving body 4 can be applied to more trash cans. By utilizing the layout of the cavity 44 and the limit block 5, the winding and unfolding of the flexible belt 6 are smoother, and the structure of the entire bag receiving body 4 is compact.

[0064] Specifically, the cavity 44 includes a top plate 42 and a bottom plate 43 provided on the upper and lower sides respectively. The circumferential sides of the top plate 42 / bottom plate 43 extend toward the bottom plate 43 / top plate 42 to form side plates.

[0065] Specifically, the second arm 2 includes an insulating base 21 and a heating element for fusing and sealing the bag opening; the insulating base 21 is provided with a heating and pressing plane 211 on the side facing the bag opening, the heating and pressing plane 211 is arranged along the length of the second arm 2, and the heating element is arranged on the heating and pressing plane 211; the first arm 1 is provided with an extrusion plane 111 on the side facing the garbage bag, the extrusion plane 111 is used to clamp the heating and pressing plane 211;

[0066] In this embodiment, the first arm 1 rotates with one end as the axis, driving its other end to approach and clamp the second arm 2. During this process, the heating element on the second arm 2 heats and melts the garbage bag. At the same time, the extrusion plane 111 of the first arm 1 and the heating pressing plane 211 of the second arm 2 are tightly clamped to ensure the integrity and sealing of the melting seal. This design greatly simplifies the steps of sealing the garbage bag, improves the sealing efficiency, and is easy to operate.

[0067] Specifically, the second arm 2 further includes first limiting grooves 213 provided at the left and right ends, and a second limiting groove 214 is provided in the middle of the heating and pressing plane 211. The first limiting grooves 213 are connected to the second limiting grooves 214 and are provided on the same plane. The heating element extends from the first limiting groove 213 at one end along the second limiting groove 214 to the first limiting groove 213 at the other end.

[0068] The first limiting groove 213 and the second limiting groove 214 are provided mainly to limit the position of the heating element to avoid inadequate melting and sealing of the garbage bag due to deviation or bending of the heating element.

[0069] Specifically, a mounting groove 215 is formed on the top of the thermal insulation base 21, and a mounting hole 2151 is formed on the bottom of the thermal insulation base 21. The mounting hole 2151 is connected to the mounting groove 215. The top plate 42 is provided with a mounting portion and a fastener. The mounting portion extends into the mounting groove 215, and the fastener passes through the mounting hole 2151 and the mounting portion in sequence for fixation.

[0070] The design of the mounting groove 215 and the mounting hole 2151 is conducive to further fixing the second arm 2 and preventing the garbage bag from being melted and sealed insufficiently due to loosening of the second arm 2.

[0071] Specifically, one end of the first arm body 1 is rotatably connected to the top plate 42 through a rotating mechanism, and the other end of the first arm body 1 is connected to the flexible belt 6; the first arm body 1 is provided with an extrusion platform 11 at a position away from the rotating mechanism, and the extrusion plane 111 is formed on one side of the extrusion platform 11.

[0072] Specifically, the rotating mechanism includes a rotating shaft 421 provided on the top plate 42 and a rotating groove 12 provided on the first arm 1, and the rotating groove 12 rotates around the rotating shaft 421;

[0073] The first arm 1 is shaped like the number 7; the rotating groove 12 is connected to the extrusion platform 11 through a folded angle 13; in this embodiment, the folded angle 13 and the design that the first arm 1 can rotate around the rotating shaft 421 enable the first arm 1 to have a greater pressing force when clamped with the second arm 2, thereby ensuring that the garbage bag can be fully melted and sealed.

[0074] Specifically, the heat-insulating base 21 is provided with two protrusions 212 at one end close to the rotating mechanism, each protrusion 212 protrudes from the heating and pressing plane 211, and the two protrusions 212 are symmetrically arranged in the upper and lower directions; the first arm 1 is provided with two avoidance grooves 14 at the corner 13 to cooperate with the protrusions 212, and the two avoidance grooves 14 are symmetrically arranged in the upper and lower directions on the extrusion platform 11;

[0075] In this embodiment, the design of the protrusion 212 and the avoidance groove 14 is conducive to preventing the garbage bag from getting stuck in the gap between the first arm 1 and the second arm 2, so as to ensure that the garbage bag can be completely melted and sealed.

[0076] Two connecting grooves 15 are provided at one end of the first arm 1 connected to the flexible belt 6 . The two connecting grooves 15 are symmetrically arranged on the upper and lower sides of the extrusion platform 11 . The two connecting grooves 15 are connected through a connecting hole 151 .

[0077] Specifically, the second arm 2 is provided with a flange 22 at one end away from the insulation base 21; the limit block 5 is provided with a slot 53 for the flange 22 to pass through; when the flange 22 is completely engaged with the slot 53, the flexible belt 6 stops further retracting;

[0078] The design of the flange 22 and the bayonet 53 ensures that when the limit block 5 is connected to the fuse 3, the garbage bag is completely placed within the melting range of the fuse 3 after being tightened by the flexible belt 6, further improving the sealing effect of the garbage bag and preventing the garbage bag from leaking when sealed.

[0079] Specifically, the heating element is a strip-shaped heating wire; the second limiting groove 214 is provided along the length of the second arm 2; when the heating wire is provided in the second limiting groove 214, the heating wire portion protrudes from the heating and pressing plane 211;

[0080] It should be noted that, except for the heating element, the fuse 3 is made of insulating material, which can effectively isolate the heat generated by the fuse 3 during operation from being transferred to the external environment, reducing damage to the garbage bag and garbage can due to overheating.

[0081] Specifically, the limit block 5 is provided with a sliding groove 51 for the flexible belt 6 to pass through, and the flexible belt 6 is transmission-connected to the limit block 5 through the sliding groove 51; the top plate 42 is provided with a guide rail 422 for the limit block 5 to slide, and the top of the limit block 5 is provided with a protrusion 52 that is slidably connected to the guide rail 422, and the width of the guide rail 422 is greater than the diameter of the protrusion 52;

[0082] The design of the sliding groove 51 not only allows the flexible belt 6 to slide smoothly, but also limits the flexible belt 6 from deviating from the track 45, so that the process of automatic winding and unfolding of the flexible belt 6 is smoother; at the same time, the design of the limit block 5 is conducive to guiding the flexible belt 6 to be wound within the melting range of the fuse 3, avoiding the problem of bag leakage due to insufficient sealing of the garbage bag.

[0083] Specifically, it further includes an elastic member 8, one end of the elastic member 8 is fixed to the top plate 42, and the other end is elastically connected to the protrusion 52; the elastic extension direction of the elastic member 8 is the same as the extension direction of the guide rail 422;

[0084] It should be noted that the elastic member 8 is a spring; the stretched elastic member 8 generates a reaction force, thereby driving the limit block 5 to move along the guide rail 422 .

[0085] In this embodiment, the flexible belt 6 is inserted into the sliding groove 51 from top to bottom or from bottom to top, and the groove width of the sliding groove 51 is greater than the thickness of the flexible belt 6, so that a clearance fit is formed between the flexible belt 6 and the sliding groove 51;

[0086] When the flexible belt 6 is loosely fitted with the sliding groove 51, the movement speed of the flexible belt 6 when tightened is greater than the movement speed of the limit block 5. Since the flexible belt 6 and the limit block 5 move synchronously, the movement stroke of the limit block 5 is shortened while ensuring its function, the volume of the limit block 5 structure is reduced, and the installation space of the limit block 5 structure is saved.

[0087] Specifically, a track 45 is provided in the cavity 44 and is arranged to rotate from the inside to the outside; the inner side of the track 45 is open to form the lateral opening;

[0088] More specifically, at least a support portion is provided in the cavity 44 , and the track 45 is provided on the support portion in a spiral manner from the inside to the outside; the bottom plate 43 forms the support portion;

[0089] The track 45 described in this embodiment is used to limit the flexible belt 6 that is collecting the garbage bag, so that the flexible belt 6 can be smoothly rolled up or unfolded from the inside of the track 45, avoiding the flexible belt 6 from deviating during the movement.

[0090] The winding wheel 7 is in transmission connection with a driving member;

[0091] Specifically, the driving member is a driving motor, which is used to directly or indirectly drive the winding wheel 7 to rotate;

[0092] It should be noted that the winding wheel 7 is a toothed belt winding wheel 7; the flexible belt 6 is provided with an interlocking portion that is transmission-connected to the winding wheel 7 to ensure that the teeth on the toothed belt winding wheel 7 can cooperate with the interlocking portion, so that the toothed belt winding wheel 7 can better and more smoothly drive the flexible belt 6 to reciprocate, thereby preventing the flexible belt 6 from getting out of control.

[0093] like Figure 6 and Figure 13 As shown, the use process of the flexible belt bag collecting mechanism for a trash can described in this embodiment is as follows:

[0094] The driving member drives the winding wheel 7 to rotate, and the winding wheel 7 drives the flexible belt 6 to be wound from the inner side of the track 45 to the fuse 3; the bag opening of the garbage bag is retracted to the fuse 3 by the flexible belt 6, and at this time, the flexible belt 6 drives the first arm 1 to rotate toward the second arm 2 around the rotating shaft 421, and the heating wire starts to heat up, and the extrusion plane 111 clamps the bag opening of the garbage bag toward the heating and pressing plane 211, and the bag opening of the garbage bag is melted by the heating wire and split into two.

[0095] The driving member drives the winding wheel 7 to rotate in the opposite direction, and the winding wheel 7 drives the flexible belt 6 to unfold, and the flexible belt 6 drives the first arm 1 to rotate and reset around the rotating shaft 421. The second arm 2 is separated from the limit block 5, and the flexible belt 6 is gradually unfolded along the track 45 at the same time, and the bag opening of the garbage bag loses its squeeze and loosens.
