Description

Technical Field

[0001] The utility model belongs to the technical field of trash cans, and in particular relates to a clamping type fuse structure for a trash can. Background Art

[0002] Traditional trash cans require manual bagging after they're full, a cumbersome process that easily stains hands and is unhygienic. With the advancement of technology, smart trash cans have emerged that can automatically bag trash, significantly increasing the automation of waste disposal. These cans typically use one or two pressure bars / plates to press the bag's opening against the edge of the can, and then a sealing device works in conjunction with the bars / plates to seal and bag the bag.

[0003] For example, in the prior art, Chinese patent publication number CN106564717B discloses a device and method for automatically heat-sealing garbage bags in a trash can. It also mentions that a clamping plate moves toward a heating module under the push of a driving mechanism. When the clamping plate contacts the heating module, the opening of the garbage bag is closed. At this time, the heating module is started, thereby melting the opening of the garbage bag.

[0004] However, this existing technology still has drawbacks in practical application:

[0005] (1) The clamping plate and the heating module are both made of rigid materials, and the contact area between the two is large. Although this helps 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. Even during the sealing process, if the heating module generates too high a temperature, it can easily damage other components inside the garbage can or cause safety hazards such as fire.

[0006] (2) 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;

[0007] (3) Most of the pressing plates / pressing rods have a flat structure on the side that contacts the heating module. Once the flat structure is bent, the pressed garbage bag cannot fully contact the heating module, which may easily cause the garbage bag to be poorly sealed and reduce the reliability and practicality of the packaging.

[0008] Therefore, there is an urgent need for a clamp-type trash can fuse structure that can better seal the trash bag and solve the above-mentioned problems. Summary of the Invention

[0040] like Figure 1-2 As shown, this embodiment provides a clamp-type trash can fuse structure, including a fuse body arranged at the mouth of the trash can, which is used to fuse and seal the folded trash bag.

[0041] The fuse body includes a first clamping arm 1 and a second clamping arm 2; one end of the first clamping arm 1 is connected to a belt 3 for collecting the garbage bag, and the belt 3 is continuously retracted under external force; the first clamping arm 1 has one end as the axis, and the other end is driven by the belt 3 to drive the entire first clamping arm 1 to rotate open or close relative to the second clamping arm 2;

[0042] The second clamping arm 2 includes an insulating base 21 and a heating element for melting and sealing the garbage bag; the insulating base 21 is provided with a heating and pressing plane 211 on the side facing the garbage bag, the heating and pressing plane 211 being arranged along the length of the second clamping arm 2, and the heating element is arranged on the heating and pressing plane 211; the first clamping arm 1 is provided with an extrusion plane 111 on the side facing the garbage bag, the extrusion plane 111 being used to clamp the heating and pressing plane 211;

[0043] The clamping-type trash can fuse structure provided in this embodiment has a clamping mechanism designed between the first clamping arm 1 and the second clamping arm 2, so that the fuse body has a clamping function similar to that of a clamp, which can effectively achieve efficient fusing and sealing of the folded trash bag. Driven by the belt body 3, the first clamping arm 1 rotates around one end as the axis, driving its other end to approach and clamp the second clamping arm 2. During this process, the heating element on the second clamping arm 2 heats and fuses the trash bag. At the same time, the extrusion surface 111 of the first clamping arm 1 and the heating and pressing surface 211 of the second clamping arm 2 are tightly clamped to ensure the integrity and sealing of the fusing seal. This design greatly simplifies the garbage bag sealing mechanism, improves the sealing efficiency, and is easy to operate.

[0044] In addition, the design of the insulating base 21 and the heating pressing plane 211 described in this embodiment ensures that heat can be concentrated and evenly applied to the garbage bag, avoiding safety hazards caused by heat loss or local overheating; at the same time, the clamping operation method also reduces the accidental injuries that may be caused by directly holding the heating element for sealing, further improving the safety of the product.

[0045] The first clamping arm 1 is rotatably connected to the mouth of the trash can through a rotating mechanism at the end not connected to the belt body 3; the first clamping arm 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.

[0046] Specifically, the rotating mechanism includes a rotating shaft provided at the mouth of the trash can, and a rotating slot 12 provided on the first clamping arm 1, and the rotating slot 12 rotates around the rotating shaft;

[0047] like Figure 3-8 As shown, the shape of the first clamping arm 1 is in the shape of a number 7; the rotating groove 12 is connected to the extrusion platform 11 through a folded angle 13;

[0048] In this embodiment, the folded corner 13 and the design that the first clamping arm 1 can rotate around the rotating axis enable the first clamping arm 1 to have a greater pressing force when clamped with the second clamping arm 2, thereby ensuring that the garbage bag can be fully melted and sealed.

[0049] Specifically, the 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 clamping 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;

[0050] 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 clamping arm 1 and the second clamping arm 2, so as to ensure that the garbage bag can be completely melted and sealed.

[0051] Specifically, one end of the first clamping arm 1 connected to the belt body 3 is provided with two connecting grooves 15, and 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;

[0052] Specifically, the second clamping arm 2 is provided with a flange 22 at one end away from the heat-insulating base 21; the trash can mouth is provided with a stopper, the belt body 3 passes through the stopper, and the stopper is provided with a slot for the flange 22 to pass through; when the flange 22 is fully engaged with the slot, the belt body 3 stops further retracting;

[0053] The designs of the connecting groove 15, the connecting hole 151 and the flange 22 are all to further cooperate with the structure of the trash can to collect the trash bag, so as to ensure that the trash bag can be completely collected and melted and sealed in the end.

[0054] Specifically, the second clamping 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;

[0055] 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.

[0056] Specifically, the heating element is a strip-shaped heating wire; the second limiting groove 214 is provided along the length of the second clamping 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;

[0057] In this embodiment, the heating element is designed as a strip-shaped heating wire, which is conducive to linear melting of the garbage bag, thereby allowing the garbage bag to be split into two at the melting position; at the same time, it is conducive to reducing the contact area between the garbage bag and the heating element, avoiding damage to the garbage bag due to excessive heating.

[0058] Specifically, a mounting groove 215 is formed on the top of the insulating base 21, and a mounting hole 2151 is formed on the bottom of the insulating base 21.

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 fixing.

[0059] The design of the mounting groove 215 and the mounting hole 2151 is conducive to further fixing the second clamping arm 2 and preventing the garbage bag from being melted and sealed insufficiently due to the loosening of the second clamping arm 2.

[0060] Specifically, the fuse body, except for the heating element, is made of heat-insulating material; the heating element is connected to the hot-melt circuit;

[0061] In this embodiment, in addition to the heating element, the fuse body is made of insulating material, which can effectively isolate the heat generated by the fuse body during operation from being transferred to the external environment, reduce damage to garbage bags and garbage cans due to overheating, and even avoid fire, thereby significantly improving the safety performance of the equipment; at the same time, the application of insulating material helps to extend the service life of the fuse body and other non-heating components inside the garbage can, avoid problems such as material aging and performance degradation caused by long-term heat, so as to improve the overall reliability and durability of the clamp-type garbage can fuse structure.

[0062] like Figure 9 As shown, the use process of the clamp-type trash can fuse structure described in this embodiment is as follows:

[0063] The garbage bag is gathered to the fuse body by the belt body 3. At this time, the belt body 3 drives the first clamping arm 1 to rotate around the rotating shaft toward the second clamping arm 2, the heating wire starts to heat up, and the extrusion plane 111 clamps the garbage bag toward the heating and pressing plane 211. The garbage bag is melted by the heating wire and split into two; the belt body 3 drives the first clamping arm 1 to rotate and reset around the rotating shaft to complete the melting and sealing of the garbage bag.
