Description

Technical Field

[0001] This utility model relates to the field of cat litter box technology, and in particular to a packaging device with a bag-removing structure and a cat litter box having the same. Background Technology

[0002] The litter box packaging device is a device that fuses and cuts the garbage bag containing cat feces to separate the garbage bag containing cat feces. At the same time, it is a device that seals the bottom of the garbage bag to be used. It mainly uses a pressing mechanism to press the two sides together and then uses a heat fusion component to fuse and separate them.

[0003] After the garbage bag is melted, the pressing mechanism resets. However, because the garbage bag and the hot-melt component still retain a certain temperature, the garbage bag is prone to sticking to the pressing mechanism on the left or right side, causing the garbage bag to fail to detach and fall off in time. This results in a low success rate of bag detachment and low packaging efficiency.

[0004] Some existing packaging devices use a bag-removing structure that pushes the bag out by a single telescopic rod. This design has a fundamental flaw: due to the lack of a mechanical linkage mechanism with the pressing block mechanism on the other side, the single telescopic rod needs an independent drive source to trigger the action, which not only increases energy consumption and maintenance costs, but also leads to a mismatch between the timing of the push-out and the movement of the moving parts. This may cause mechanical interference when the equipment is closed, and it is difficult to ensure that the hot melt bag is completely detached from the fixing parts, resulting in a high bag removal failure rate. Utility Model Content

[0005] The main purpose of this utility model is to propose a packing device with a bag-removing structure and a cat litter box with the same structure, in order to solve the problems of low bag removal success rate and low packing efficiency caused by the lack of a bag-removing structure in the prior art, as well as the unreliable ejection action, high energy consumption and equipment interference caused by the lack of a motion coordination mechanism in the single telescopic rod scheme.

[0006] To achieve the above objectives, this utility model proposes a packaging device with a bag-removing structure, including a fixing member, a heat-sealing member, and a movable member that can move relative to the fixing member, and further including:

[0007] The first pusher is movably mounted on the fixing member;

[0008] The second pusher is movably disposed on the movable member;

[0009] The fixing member and the moving member have a first position where they are relatively closed and a second position where they are relatively separated.

[0010] When the fixing member and the moving member are in the first position, the heat-melting member heat-melts the garbage bag together, and the first pusher and the second pusher respectively clamp the garbage bag between the two sides of the garbage bag;

[0011] When the fixing member and the moving member transition from the first position to the second position, the first pusher moves away from the fixing member and / or the second pusher moves away from the moving member to maintain the clamping of the garbage bag, so as to release the adhesion between the heat-melted garbage bag and the fixing member and / or the garbage bag and the moving member.

[0012] When the fixing member and the moving member are in the second position, the first pusher and the second pusher separate from each other.

[0013] Preferably, the first pusher and the second pusher are connected and separated by a magnetic adsorption structure;

[0014] The magnetic adsorption structure includes:

[0015] A first magnetic component and a second magnetic component with opposite polarities, wherein the first magnetic component is disposed on the first pusher and the second magnetic component is disposed on the second pusher;

[0016] When the fixing member and the moving member are in the first position, the magnetic attraction between the first magnetic member and the second magnetic member is greater than the separation resistance, and the two are attracted and adhered together.

[0017] When the fixed member and the moving member are in the second position, the magnetic attraction between the first magnetic member and the second magnetic member is less than the separation threshold, and the two automatically separate.

[0018] Preferably, the first pusher is provided with at least one first guide post, which is movably inserted into the fixing member to realize the movable assembly of the first pusher and the fixing member. The end of the first guide post away from the first pusher is provided with a first limiting part, so as to restrict the first pusher from completely disengaging from the fixing member by the abutting cooperation between the first limiting part and the fixing member.

[0019] Preferably, the first guide post is fitted with a first top spring, one end of which elastically abuts against the fixing member, and the other end of which elastically abuts against the first push member. The first top spring can apply an elastic force to the first push member to move away from the fixing member.

[0020] Preferably, the fixing member is provided with a first receiving groove adapted to the first push member at the position corresponding to the first push member, and the first push member can move relative to the fixing member between the position of entering the first receiving groove and the position of moving away from it.

[0021] Preferably, the second pusher is provided with at least one second guide post, which is movably inserted into the moving member to realize the movable assembly of the second pusher and the moving member. The end of the second guide post away from the second pusher is provided with a second limiting part, so as to restrict the second pusher from completely disengaging from the moving member by the abutting cooperation between the second limiting part and the moving member.

[0022] Preferably, the second guide post is fitted with a second top spring. One end of the second top spring elastically abuts against the side of the moving member away from the fixed member, and the other end elastically abuts against the second limiting part. The second top spring can apply a spring force to the second push member in the direction of moving against the moving member.

[0023] Preferably, the movable member is provided with a second receiving groove corresponding to the position of the second pusher, and the second pusher can move relative to the movable member between a position entering the second receiving groove and a position away from it.

[0024] Preferably, the hot melt component is disposed on the fixing component, and the first pusher is disposed on the fixing component at a position corresponding to the bottom of the hot melt component.

[0025] This utility model also proposes a cat litter box, including the above-mentioned packaging device with a bag-removing structure.

[0026] The beneficial effects of this utility model are:

[0027] This invention features a first pusher and a second pusher movably mounted on a fixing component and a moving component, respectively. When the fixing component and the moving component are in a first position where they are relatively closed, the garbage bag sandwiched between them can be thermally fused together using a heat-fusion component. Simultaneously, the first and second pushers cooperate to clamp the garbage bag. As the fixing component and the moving component transition from the first position to the second position, the first pusher moves away from the fixing component, and / or the second pusher moves away from the moving component, synchronously and automatically detaching the thermally fused garbage bag during the resetting process of the moving component. When the fixing component and the moving component are in the second position, the first and second pushers separate, releasing the clamped garbage bag and allowing it to fall automatically. This effectively solves the problem of difficulty in removing the garbage bag caused by adhesion between the garbage bag and the fixing or moving component. This structure requires no additional drive or manual intervention, significantly improving the success rate of bag removal and packaging efficiency. Furthermore, the overall structure is compact, reliable, and easy to implement and maintain. Attached Figure Description

If the specific posture changes, the directional indication will also change accordingly.

[0035] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0036] This utility model proposes a packaging device with a bag-removing structure.

[0037] In this embodiment of the utility model, such as Figures 1 to 4 As shown, the packing device with a bag-removing structure includes a fixing member 1, a heat-sealing member 2, a movable member 3 that can move relative to the fixing member 1, a first pusher 4, and a second pusher 5;

[0038] The first pusher 4 is movably disposed on the fixed member 1; the second pusher 5 is movably disposed on the movable member 3; the fixed member 1 and the movable member 3 have a first position of relative engagement and a second position of relative separation.

[0039] When the fixing member 1 and the moving member 3 are in the first position, the hot melt member 2 heat melts and fuses the garbage bag together, and the first pusher 4 and the second pusher 5 respectively clamp the garbage bag between the two sides of the garbage bag.

[0040] When the fixing member 1 and the moving member 3 transition from the first position to the second position, the first pusher 4 moves away from the fixing member 1 and / or the second pusher 5 moves away from the moving member 3 to maintain the clamping of the garbage bag, so as to release the adhesion between the heat-melted garbage bag and the fixing member 1 or / and the garbage bag and the moving member 3.

[0041] When the fixing member 1 and the moving member 3 are in the second position, the first pushing member 4 and the second pushing member 5 are separated from each other.

[0042] Specifically, the first pusher 4 and the second pusher 5 are connected and separated by a magnetic adsorption structure;

[0043] The magnetic adsorption structure includes:

[0044] A first magnetic element 6 and a second magnetic element 7 with opposite polarities, wherein the first magnetic element 6 is disposed on the first pusher 4 and the second magnetic element 7 is disposed on the second pusher 5;

[0045] When the fixing member 1 and the moving member 3 are in the first position, the magnetic attraction between the first magnetic member 6 and the second magnetic member 7 is greater than the separation resistance, and the two are attracted and adhered together.

[0046] When the fixing member 1 and the moving member 3 are in the second position, the magnetic attraction between the first magnetic member 6 and the second magnetic member 7 is less than the separation threshold, and the two automatically separate.

[0047] Specifically, in another embodiment, the first pusher 4 and the second pusher 5 are connected and separated by an electromagnet-type adsorption structure, and magnetic adsorption or demagnetization is achieved by energizing or de-energizing.

[0048] Specifically, in another embodiment, the first pusher 4 and the second pusher 5 are connected or separated by a plug-in structure:

[0049] For example, a plunger pin with a conical or ball-shaped head is provided in the first pusher 4, and a slot is provided in the corresponding position in the second pusher 5. When the fixing member 1 and the moving member 3 abut against each other, the plunger pin is inserted into the slot, and the conical or ball-shaped head elastically abuts against the inner wall of the slot to form an interference fit. When the second position is not exceeded, the first pusher 4 and / or the second pusher 5 are driven to extend, thereby relieving the sticking problem of the garbage bag. When the fixing member 1 and the moving member 3 transition to the second position, they exceed the movable range of the first pusher 4 and the second pusher 5, causing the conical or ball-shaped head to be forced to disengage from the slot, thereby realizing the separation of the first pusher 4 and the second pusher 5.

[0050] Understandably, the first and second positions are achieved by the movement of the moving part 3. During heat melting, the moving part 3 moves in the direction of opposing the fixed part 1, and during reset, it moves away from the fixed part 1. When the distance between the moving part 3 and the fixed part 1 is less than X, it is the first position; when the distance between the moving part 3 and the fixed part 1 is equal to or greater than X, it is the second position. According to actual use, X can be set to 10 cm, 15 cm, 20 cm, etc.

[0051] Specifically, the number of the first magnetic element 6 and the second magnetic element 7 is at least one.

[0052] Specifically, the first pusher 4 is provided with at least one first guide post 41. The first guide post 41 is movably inserted into the fixing member 1 to realize the movable assembly of the first pusher 4 and the fixing member 1. The end of the first guide post 41 away from the first pusher 4 is provided with a first limiting part 42, so as to restrict the first pusher 4 from completely disengaging from the fixing member 1 by the abutting cooperation between the first limiting part 42 and the fixing member 1.

[0053] Specifically, the first guide post 41 is fitted with a first top spring 43. One end of the first top spring 43 elastically abuts against the fixing member 1, and the other end elastically abuts against the first push member 4. The first top spring 43 can apply an elastic force to the first push member 4 to move away from the fixing member 1.

[0054] Specifically, the fixing member 1 is provided with a first receiving groove 44 corresponding to the position of the first push member 4, and the first push member 4 can move relative to the fixing member 1 between entering the first receiving groove 44 and moving away from it.

[0055] Specifically, one end of the first top spring 43 elastically abuts against the wall of the first receiving groove 44, and the other end elastically abuts against the first pusher 4.

[0056] Specifically, the second pusher 5 is provided with at least one second guide post 51. The second guide post 51 is movably inserted into the moving member 3 to realize the movable assembly of the second pusher 5 and the moving member 3. The end of the second guide post 51 away from the second pusher 5 is provided with a second limiting part 52 to restrict the second pusher 5 from completely disengaging from the moving member 3 through the abutting cooperation between the second limiting part 52 and the moving member 3.

[0057] Specifically, the second guide post 51 is fitted with a second top spring 53. One end of the second top spring 53 elastically abuts against the side of the moving member 3 away from the fixed member 1, and the other end elastically abuts against the second limiting part 52. The second top spring 53 can apply a spring force to the second push member 5 in the direction of moving against the moving member 3.

[0058] Specifically, the movable member 3 is provided with a second receiving groove corresponding to the position of the second pusher 5, and the second pusher 5 can move relative to the movable member 3 between entering the second receiving groove and moving away from it.

[0059] Specifically, the heat-fused component 2 is disposed on the fixing component 1, and the first pusher 4 is disposed on the fixing component 1 at a position corresponding to the lower part of the heat-fused component 2. The second pusher 5 is located on the moving component 3 at a position corresponding to the first pusher 4.

[0060] Specifically, the first pusher 4 and the second pusher 5 are elongated strips.

[0061] During operation, the movable part 3 moves toward the fixed part 1 and abuts against the fixed part 1 to partially clamp the garbage bag. The garbage bag is then separated by the hot melt part 2 through hot melt cutting. The first pusher 4 and the second pusher 5 are in opposite positions. When the movable part 3 and the fixed part 1 abut against each other, the second pusher 5 pushes the first pusher 4 to move, causing the first pusher 4 to move into the first receiving groove 44. The first top spring 43 is then compressed. During this period, the first magnetic part 6 and the second magnetic part 7 attract each other due to the mutual approach of the first pusher 4 and the second pusher 5.

[0062] After the hot melting is completed, the moving part 3 returns to its original position. During the return and reset process, the first top spring 43 is released from its compressed state, and the released potential energy causes the first pusher 4 to gradually extend out of the first receiving groove 44. Meanwhile, the second pusher 5 is pulled out of the second receiving groove (not shown) because the magnetic attraction between the first magnetic element 6 and the second magnetic element 7 is greater than the separation threshold. This allows the first pusher 4 and the second pusher 5 to push the sticky garbage bag to separate it from the hot-melted part 2. The second top spring 53 is then compressed. As the moving part 3 continues to move back to a certain position, when the magnetic attraction between the first magnetic element 6 and the second magnetic element 7 is greater than the separation threshold, the first pusher 4 and the second pusher 5 automatically separate, and the garbage bag sandwiched between them falls off. The second top spring 53 is released from its compressed state, and the released potential energy causes the second pusher 5 to return to the second receiving groove (not shown).

[0063] Specifically, in one embodiment, the fixing member 1 is provided with a second first push member 4 at a position above the hot melt member 2, and the moving member 3 is provided with a second second push member 5 at a position corresponding to the second first push member 4. After the garbage bag is fused and broken, it forms an upper part and a lower part. Both the upper and lower parts may stick together. Therefore, the first push member 4 and the second push member 5 located below the hot melt member 2 can cooperate to relieve the sticking problem of the lower part, while the first push member 4 and the second push member 5 located above the hot melt member 2 can cooperate to relieve the sticking problem of the upper part.

[0064] This utility model also proposes a cat litter box, including the above-mentioned packaging device with a bag-removing structure. For the specific structure of the packaging device with a bag-removing structure, please refer to the above embodiments. Since this cat litter box adopts all the technical solutions of all the above-mentioned packaging devices with a bag-removing structure, it has at least all the beneficial effects brought about by the technical solutions of the above-mentioned packaging devices with a bag-removing structure, which will not be repeated here.

[0065] It should be noted that the specific movement of the moving part 3 relative to the fixed part 1 can be directly referred to the existing technology, such as the telescopic cylinder drive method, the linear motor drive method, etc., and its specific structural principle will not be elaborated here.

[0066] The beneficial effects of this utility model are:

[0067] This invention features a first pusher and a second pusher movably mounted on a fixing component and a moving component, respectively. When the fixing component and the moving component are in a first position where they are relatively closed, the garbage bag sandwiched between them can be thermally fused together using a heat-fusion component. Simultaneously, the first and second pushers cooperate to clamp the garbage bag. As the fixing component and the moving component transition from the first position to the second position, the first pusher moves away from the fixing component, and / or the second pusher moves away from the moving component, synchronously and automatically detaching the thermally fused garbage bag during the resetting process of the moving component. When the fixing component and the moving component are in the second position, the first and second pushers separate, releasing the clamped garbage bag and allowing it to fall automatically. This effectively solves the problem of difficulty in removing the garbage bag caused by adhesion between the garbage bag and the fixing or moving component. This structure requires no additional drive or manual intervention, significantly improving the success rate of bag removal and packaging efficiency. Furthermore, the overall structure is compact, reliable, and easy to implement and maintain.
