Description

Technical Field

[0001] The invention belongs to the technical field of trash cans, and in particular relates to an automatic packing trash can with a flexible belt and a folding bag opening. Background Art

[0002] With the development of society and the improvement of people's living standards, the requirements for garbage disposal are also increasing. There are many inconveniences in the use of traditional trash cans, such as the loose sealing of garbage bags leading to odor, the unsanitary operation of users tying garbage bags with their hands, and the cumbersome operation of collecting bags. Moreover, when the lid of the trash can is opened, the garbage in the bucket is easily exposed or seen by the user. If the garbage in the bucket is some private garbage such as diapers and sanitary napkins, it is easy to cause discomfort to the user in terms of perception and smell. Therefore, with the advancement of social science and technology, people have put forward higher requirements for the functions of trash cans in preventing odor from drifting, preventing sanitary infections, preventing privacy exposure, and sealing and isolation.

[0003] In order to solve these problems, trash cans that can automatically pack garbage bags have gradually appeared on the market, which significantly improves the automation of garbage disposal. These trash cans usually use one or two pressure rods / pressing plates to press the garbage bag mouth to the edge of the barrel mouth, and then the sealing device cooperates with the pressure rod / pressing plate to complete the sealing and packaging. As in the prior art, a Chinese patent with publication number CN106564717B discloses a garbage can automatic heat-sealing garbage bag device and method, which also mentions that the clamping plate moves toward the heating module under the push of the driving mechanism. When the clamping plate contacts the heating module, the garbage bag mouth is closed. At this time, the heating module is started to melt the garbage bag mouth.

[0004] However, the above-mentioned prior art still has many deficiencies in practical application:

[0005] (1) The device structure is complex, requiring the additional installation of multiple components such as sliders, guide rails, clamping plates, synchronous pulley sets, etc., which makes the control more complicated and the manufacturing cost high;

[0006] (2) Both the clamping plate and the heating module are made of rigid materials, and the contact area between the two 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, reducing 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 plate / pressing rod is 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 an automatic packaging trash can with a flexible belt and a foldable bag opening to solve the above problems. Summary of the invention

[0069] like Figure 1-5 As shown, this embodiment provides an automatic packing trash can with a flexible belt for closing the bag opening, comprising a trash can body and a trash can cover 3, wherein the trash can body has an upward trash can opening, and the trash can cover 3 covers the trash can opening; a trash can collecting mechanism 4 is also provided at the trash can opening, and a throwing opening 41 is provided in the middle of the trash can collecting mechanism 4; a cavity for placing a trash bag is provided in the trash can body, and the opening of the trash bag is located in the throwing opening 41;

[0070] The middle part of the bag receiving mechanism 4 is connected with the throwing port 41; the opening of the garbage bag is set on the throwing port 41, and the bag body passes through the middle part of the bag receiving mechanism 4; the bag receiving mechanism 4 is provided with an annular cavity 44 around the throwing port 41, and the inner side of the cavity 44 is open and connected with the throwing port 41 of the garbage bin; at least a support part is provided in the cavity 44, and a track 45 is provided on the support part from the inside to the outside;

[0071] The bag collecting mechanism 4 further includes a fuse 10, a limit block 5, a flexible belt 6 and a driving wheel 7 arranged in the cavity 44; one end of the fuse 10 is connected to one end of the flexible belt 6, and the other end of the fuse 10 is provided with the driving wheel 7; the other end of the flexible belt 6 extends along the track 45 and passes through the limit block 5 and is transmission-connected to the driving wheel 7; the driving wheel 7 rotates and drives the flexible belt 6 to be elastically rolled up or unfolded;

[0072] The flexible belt 6 is rolled up from the inner side of the track 45 to the fuse 10. At this time, the fuse 10, the limit block 5 and the flexible belt 6 are surrounded in a closed state. The bag opening of the garbage bag is drawn to the fuse 10 by the flexible belt 6. The fuse 10 squeezes the bag opening and melts the seal. The driving wheel 7 rotates in the opposite direction, the fuse 10 is separated from the limit block 5, and the flexible belt 6 is simultaneously unfolded along the track 45, and the bag opening of the garbage bag loses squeezing.

[0073] In this embodiment, the flexible belt 6 is automatically rolled up and unfolded by the driving 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.

[0074] Secondly, compared with the sealing structure of the pressure rod / pressure plate of the existing trash can, the bag collecting mechanism 4 of this embodiment has a simpler structure, and the operation process of controlling the winding or unfolding of the flexible belt 6 is simple;

[0075] Moreover, the present embodiment uses the fuse 10 to heat and seal the garbage bag, which is more environmentally friendly and saves materials compared to the traditional manual knotting or additional tape sealing;

[0076] In addition, the bag collecting mechanism 4 described in this embodiment is cleverly arranged at the mouth of the barrel, so that the bag collecting mechanism 4 can be applied to more trash cans. By utilizing the layout of the cavity 44, the limit block 5 and the track 45, the winding and unfolding of the flexible belt 6 are smoother, and the structure of the entire automatic packaging trash can is compact, does not occupy too much additional space, and is suitable for use in various environments such as various homes and offices.

[0077] like Figure 8-12 As shown, the fuse 10 includes a first clamp arm 1 and a second clamp arm 2; the first clamp arm 1 uses one end as the axis, and the other end drives the entire first clamp arm 1 to rotate relative to the second clamp arm 2 to open or close;

[0078] In this embodiment, the flexible belt 6 is continuously retracted under the drive of the driving wheel 7, and it is the retracted flexible belt 6 that gradually drives the garbage bag into the fusion welding area of ​​the fuse 10. At the same time, the flexible belt 6 is also the power source for driving the first clamping arm 1 and the second clamping arm 2 to clamp. Through a power source (flexible belt), this embodiment can simultaneously realize multiple functions such as driving, clamping and fusing and sealing of the garbage bag, which greatly simplifies the complexity of the overall structure and reduces the manufacturing cost.

[0079] The second clamp 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 clamp arm 2, and the heating element is arranged on the heating and pressing plane 211; the first clamp arm 1 is provided with an extrusion plane 111 on the side facing the garbage bag, and the extrusion plane 111 is used to clamp with the heating and pressing plane 211;

[0080] The clamp-type fuse structure provided in this embodiment has a clamping mechanism of the first clamping arm 1 and the second clamping arm 2, so that the fuse 10 has a clamping function similar to that of a clamp, and can effectively realize efficient fusing and sealing of the folded garbage bag; the first clamping arm 1 rotates with 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 garbage bag, and at the same time, the extrusion plane 111 of the first clamping arm 1 is tightly clamped with the heating pressing plane 211 of the second clamping arm 2 to ensure the integrity and sealing of the fusing seal. This design greatly simplifies the steps of sealing the garbage bag, improves the sealing efficiency, and is easy to operate;

[0081] 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.

[0082] Specifically, the second clamping arm 2 further includes first limiting grooves 213 disposed at the left and right ends, and a second limiting groove 214 is provided in the middle of the heating and pressing plane 211, and each of the first limiting grooves 213 is connected to the second limiting grooves 214 and is disposed 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;

[0083] The first limiting groove 213 and the second limiting groove 214 are provided mainly to limit the position of the heating element to avoid the inadequate melting and sealing of the garbage bag caused by the displacement and bending of the heating element;

[0084] Specifically, a mounting groove 215 is formed at the top of the thermal insulation base 21, and a mounting hole 2151 is formed at the bottom of the thermal insulation base 21, wherein the mounting hole 2151 is communicated with the mounting groove 215; the top plate 42 is provided with a mounting portion and a fastener, wherein 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;

[0085] The design of the mounting groove 215 and the mounting hole 2151 is conducive to further fixing the second clamp arm 2 to prevent the garbage bag from being melted and sealed insufficiently due to the loosening of the second clamp arm 2.

[0086] Specifically, one end of the first clamp arm 1 is rotatably connected to the top plate 42 in the cavity 44 through a rotating mechanism, and the other end of the first clamp arm 1 is connected to the flexible belt 6; the first clamp 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;

[0087] The rotating mechanism includes a rotating shaft 421 disposed on the top plate 42 and a rotating groove 12 disposed on the first clamping arm 1, and the rotating groove 12 rotates around the rotating shaft 421;

[0088] 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;

[0089] In this embodiment, the folded corner 13 and the design that the first clamp arm 1 can rotate around the rotating shaft 421 enable the first clamp arm 1 to have a greater pressing force when clamped with the second clamp arm 2, thereby ensuring that the garbage bag can be fully melted and sealed;

[0090] Specifically, the heat-insulating base 21 is provided with two protrusions 212 at one end close to the rotating mechanism, each of the protrusions 212 protrudes from the heating and pressing plane 211, and the two protrusions 212 are symmetrically arranged in the upper and lower parts; the first clamping arm 1 is provided with two avoidance grooves 14 cooperating with the protrusions 212 at the folding corner 13, and the two avoidance grooves 14 are symmetrically arranged in the upper and lower parts of the extrusion platform 11;

[0091] 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 clamp arm 1 and the second clamp arm 2, so as to ensure that the garbage bag can be completely melted and sealed;

[0092] Specifically, two connecting grooves 15 are provided at one end of the first clamping arm 1 connected to the flexible belt 6, 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;

[0093] The connection groove 15 and the connection hole 151 are designed to make the connection between the flexible belt 6 and the first clamp arm 1 more secure, so as to ensure that the flexible belt 6 can drive the first clamp arm 1 to completely retract the garbage bag into the fusing range of the fuse 10.

[0094] Specifically, the second clamping arm 2 is provided with a flange 22 at one end away from the heat-insulating 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;

[0095] The design of the flange 22 and the bayonet 53 ensures that when the limit block 5 is connected to the fuse 10, the garbage bag is completely placed within the fusing range of the fuse 10 after being tightened by the flexible belt 6, further improving the sealing effect of the garbage bag and reducing the risk of leakage when the garbage bag is sealed. The heating element is a strip-shaped heating wire;

[0096] Specifically, the second limiting groove 214 is arranged along the length of the second clamping arm 2; when the heating wire is arranged in the second limiting groove 214, the heating wire part protrudes from the heating and pressing plane 211;

[0097] In this embodiment, the heating element is a strip-shaped heating wire, which is conducive to linearly fusing the garbage bag, so that the garbage bag can be divided into two at the fusing 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;

[0098] Specifically, except for the heating element, the fuse 10 is made of insulating material, which can effectively isolate the heat generated by the fuse 10 during operation from being transferred to the external environment, reducing damage to garbage bags and garbage cans due to overheating; the heating element is connected to the hot melt circuit.

[0099] like Figure 13-14 As shown, 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 in the cavity 44 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 convex portion 52 slidably connected to the guide rail 422, and the width of the guide rail 422 is greater than the diameter of the convex portion 52;

[0100] 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 fusing range of the fuse 10, avoiding the problem of bag leakage caused by insufficient sealing of the garbage bag.

When the flexible belt 6 and the slide groove 51 are clearance-fitted, 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.

[0108] The end 452 of the track 45 is connected to the inner wall of the side plate, so that the inner wall of the side plate is formed as an extension of the track 45;

[0109] More specifically, an abutment portion 47 is provided on the end 452 or the extension of the track 45 , and the driving wheel 7 that drives the flexible belt 6 to reciprocate presses the flexible belt 6 against the abutment portion 47 .

[0111] Specifically, the connection between the first limiting portion 423 and the top plate 42 is tilted to form a first guide portion 424; the connection between the second limiting portion 431 and the bottom plate 43 is tilted to form a second guide portion 432; the first guide portion 424 and the second guide portion 432 are disposed opposite to each other to form a trumpet-shaped guide opening 46;

[0112] The guide opening 46 described in this embodiment is used to guide the flexible belt 6 that is collecting the garbage bag, so that the flexible belt 6 can be smoothly clamped between the first limiting portion 423 and the second limiting portion 431, thereby improving the smoothness of the flexible belt 6 when collecting the garbage bag.

[0113] Specifically, the track 45 rotates 1 time;

[0114] Or the number of revolutions of the track 45 is greater than or less than 1.

[0115] Specifically, the driving wheel 7 is connected to a driving member in a transmission manner, and the driving wheel 7 is a toothed belt reel; the flexible belt 6 is provided with an engaging portion connected to the driving wheel 7 in a transmission manner, so as to ensure that the teeth on the toothed belt reel can cooperate with the engaging portion, so that the toothed belt reel can drive the flexible belt 6 to reciprocate better and more smoothly, and prevent the flexible belt 6 from being out of control;

[0116] Specifically, the driving member is a driving motor, which is used to directly or indirectly drive the driving wheel 7 to rotate;

[0120] like Figure 5 , Figure 8 , Fig.11 and Fig.15 As shown, the use process of the automatic packaging trash can with a flexible belt and a folding bag opening described in this embodiment is as follows:

[0121] The driving member drives the driving wheel 7 to rotate, and the driving wheel 7 drives the flexible belt 6 to be rolled up from the inner side of the track 45 to the fuse 10; the opening of the garbage bag is retracted to the fuse 10 by the flexible belt 6, and at this time, the flexible belt 6 drives the first clamping arm 1 to rotate around the rotating shaft 421 toward the second clamping arm 2, the heating wire starts to heat up, and the extrusion plane 111 clamps the opening of the garbage bag toward the heating and pressing plane 211, and the opening of the garbage bag is melted by the heating wire and divided into two.

[0122] The driving member drives the driving wheel 7 to rotate in the opposite direction, and the driving wheel 7 drives the flexible belt 6 to unfold, and the flexible belt 6 drives the first clamping arm 1 to rotate and return to the original path around the rotating shaft 421, and the second clamping arm 2 is separated from the limiting block 5. At the same time, the flexible belt 6 gradually unfolds along the track 45, and the bag mouth of the garbage bag loses squeezing and loosens.
