[0002] In daily life, soft and easily deformable trash such as pet feces and rotten food inevitably accumulates on roads, lawns, and other surfaces. This trash cannot be picked up with existing trash cans. While tools like dustpans can be used to sweep it up, cleaning these tools is quite troublesome and produces a pungent odor.

[0003] Furthermore, this garbage often has a strong odor, is prone to bacterial growth, and is highly polluting. When placed with other garbage, it can lead to cross-contamination within the entire garbage bag, making cleaning more uncomfortable and increasing public health risks.

[0004] In response, some existing methods involve putting the garbage bag inside out on the hand or using a clamp to wrap and pick up the garbage, and then turning the garbage bag inside out and tightening the opening by hand. This process can easily cause physical discomfort to people. Utility Model Content

[0036] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0037] Please refer to Figures 1 to 4 A gripping device includes a clamping drive assembly 1 and a clamping assembly 2, wherein the clamping assembly 2 is connected to the clamping drive assembly 1, and the clamping assembly 2 is used to attach a package for wrapping a target to be picked up, including a tightening assembly 20 and a sealing assembly 21.

[0038] The fastening assembly 20 is disposed on the clamping end of the clamping assembly 2, and the sealing assembly 21 is disposed on the fastening assembly 20 and / or the packaging;

[0039] When the clamping end of the clamping component 2 controls the package to wrap the pickup target, the tightening component 20 is used to tighten the wrapping edge of the package, and the sealing component 21 is used to seal the wrapping edge of the package.

[0040] As can be seen from the above description, the beneficial effects of this utility model are as follows: It provides a gripping device, in which a tightening component 20 is provided on the gripping end of the clamping component 2, and a sealing component 21 is provided on the tightening component 20 and / or the packaging. When the clamping end of the clamping component 2 is driven by the clamping drive component 1 to control the packaging to wrap the picking target, the tightening component 20 tightens the wrapping edge of the packaging, and the sealing component 21 seals the wrapping edge of the packaging. There is no need to manually tighten the garbage bag. Instead, the clamping component 2 can be loosened, and the entire packaging can fall from the clamping component 2 into the garbage can by the gravity of the picking target. The sealed garbage bag effectively slows down the odor of the garbage and bacterial contamination, avoiding causing physiological discomfort to people.

[0041] Furthermore, the sealing assembly 21 is at least one of a heat-sealing assembly, a mechanical sealing assembly 21, and an adhesive sealing assembly 21.

[0042] As can be seen from the above description, the sealing method of the sealing component 21 includes, but is not limited to, heat sealing component, mechanical sealing component 21 and adhesive sealing component 21; taking heat sealing as the sealing method as an example, it can quickly and efficiently melt and seal the opening of common plastic garbage bags, and the sealing effect is firm, which can effectively suppress odor emission and liquid leakage.

[0043] Furthermore, the sealing assembly 21 includes a power supply module, a switch 210, and a heating wire 211;

[0044] The heating wire 211 is laid on the movable end of the fastening assembly;

[0045] The positive output of the power supply module is connected to one end of the heating wire 211 through the switch 210, and the negative output of the power supply module is connected to the other end of the heating wire 211.

[0046] As described above, the heating wire 211 is used as the actuating element, and the switch 210 is used as the control unit. When the clamping end clamps the opening of the garbage bag, the circuit is connected, and the heating wire 211 heats up instantly to complete the heat sealing; when released, the circuit is automatically disconnected. The operation is simple, and the energy utilization is efficient, safe and reliable.

[0047] Furthermore, the sealing assembly 21 also includes a pressure block 213;

[0048] The switch element 210 is a normally open push button switch, and the pressure block 213 is disposed opposite to the switch element 210;

[0049] When the clamping end of the clamping assembly 2 controls the package to wrap the picking target, the pressure block 213 can abut against the switch 210.

[0050] As described above, a pressure block 213 is provided opposite to the normally open push-button switch; the circuit is only connected when the clamping end is closed to a specific degree. This mechanical triggering method avoids misoperation and ensures that the heat sealing action only occurs when the garbage bag is effectively clamped, improving the safety of the equipment and the success rate of sealing.

[0051] Furthermore, the position of the pressure block 213 is adjustable in the direction of approaching or moving away from the switch element 210.

[0052] As can be seen from the above description, the adjustable position of the pressure block 213 makes the activation of the heat sealing function flexible. Users can activate the heat sealing function according to actual needs. When clamping some dry waste, the clamping component 2 can be used directly without using a garbage bag and the heat sealing function. Therefore, by adjusting the position of the pressure block 213, the switch 210 is not triggered when the clamping end is clamped.

[0053] Furthermore, the clamping end of the clamping assembly 2 is provided with a sandwich space, and the power supply module is located in the sandwich space.

[0054] As can be seen from the above description, placing the power supply module in the interlayer space of the clamping end physically isolates the power supply module from the garbage that may enter the clamping end, preventing the garbage from affecting the operation of the power supply module, improving the overall structural compactness of the device, and optimizing the spatial layout.

[0055] Furthermore, the clamping end of the clamping assembly 2 is provided with a first pressure plate 212 and a second pressure plate 200; when the clamping end of the clamping assembly 2 controls the package to wrap the picking target, the first pressure plate 212 and the second pressure plate 200 clamp the wrapping edge of the package.

[0056] As can be seen from the above description, the first pressure plate 212 and the second pressure plate 200 clamp each other to ensure that the edges of the package are fully fitted, thereby improving the sealing effect.

[0057] Furthermore, both the first pressure plate 212 and the second pressure plate 200 include at least two long strips that form a semi-enclosed structure;

[0058] Each of the elongated strips is provided with the sealing component 21;

[0059] When the clamping end of the clamping assembly 2 controls the package to wrap the picking target, the long strip of the first pressure plate 212 and the long strip of the second pressure plate 200 correspond one-to-one to press the wrapping edge of the package.

[0060] As described above, by setting at least two long strips forming a semi-enclosed structure, and installing a sealing component 21 on each strip, the opening sides of the garbage bag can be segmented or multi-line pressed and sealed when clamping the garbage bag. This structure significantly increases the sealing area, avoids stress concentration and insecure sealing problems that may occur with single-point sealing, and ensures the reliability and sealing performance of the garbage bag seal, making it particularly suitable for sealing larger or heavier garbage.

[0061] Furthermore, the clamping end of the clamping assembly 2 includes a first clamping portion and a second clamping portion that are opposite each other;

[0062] The first pressure plate 212 is disposed on the first clamping part, and the second pressure plate 200 is disposed on the second clamping part.

[0063] As can be seen from the above description, the clamping end of the clamping component 2 adopts a double-end clamping method, which is consistent with the pressing action of the first pressure plate 212 and the second pressure plate 200. This reduces the design difficulty of synchronizing the pressing action with the clamping action and improves the tightness of the fit between the components.

[0064] Furthermore, the first pressure plate 212 and the first clamping part, as well as the second pressure plate 200 and the second clamping part, are detachably connected.

[0065] As can be seen from the above description, the detachable design facilitates the replacement, cleaning and maintenance of accessories such as the heating wire 211 and the first pressure plate 212 after long-term use, so that the gripping device can maintain its gripping function while extending the service life of the heat sealing function.

[0066] Furthermore, the clamping drive assembly 1 is provided with a storage compartment for storing garbage bags.

[0067] As described above, the garbage bag and the grabbing device are integrated for carrying and storage, allowing users to access them at any time without having to search for garbage bags. This greatly improves the portability and ease of use of the equipment, enabling continuous and efficient cleaning operations.

[0068] Please refer to Figures 1 to 4 Embodiment 1 of this utility model is as follows:

[0069] A gripping device includes a clamping drive assembly 1 and a clamping assembly 2. The clamping assembly 2 is connected to the clamping drive assembly 1. The clamping assembly 2 is used to wrap a package for picking up a target, and includes a tightening assembly 20 and a sealing assembly 21. The tightening assembly 20 is disposed on the clamping end of the clamping assembly 2, and the sealing assembly 21 is disposed on the tightening assembly 20 and / or the package. When the package is controlled to wrap the target for picking up by the clamping end of the clamping assembly 2, the tightening assembly 20 is used to tighten the wrapping edge of the package, and the sealing assembly 21 is used to seal the wrapping edge of the package.

[0070] In this embodiment, the clamping component 20 includes, but is not limited to, various clamping structures such as single-end pressing, double-end clamping, multi-end tightening, and ring-shaped tightening. Both the clamping drive component 1 and the clamping component 2 can adopt existing gripping device products, such as Chinese Patent Application No. CN201720056765.6, entitled "An Integrated Waste Gathering Device." As a preferred design structure, the clamping drive component 1 and the clamping component 2 of this application adopt the structure shown in the figure.

[0071] The clamping drive assembly 1 includes a handle, a connecting rod, a transmission rod, a first swing arm, and a second swing arm. The handle is located at one end of the connecting rod, and the transmission rod is parallel to and slidably mounted on the connecting rod. One end of the transmission rod has a pull ring, which is positioned near the handle. The other end of the transmission rod is connected to one end of the first swing arm and one end of the second swing arm.

[0072] The clamping assembly 2 includes a first clamping part, a return spring, a second clamping part, and a connecting shaft. The other end of the connecting rod is connected to the connecting shaft. Both the first and second clamping parts are rotatably mounted on the connecting shaft. The first and second clamping parts rotate along the connecting shaft in two directions—approaching or moving away from each other—corresponding to clamping and releasing actions. The other end of the first swing arm rotates with the first clamping part, and the second swing arm is rotatably connected to the second clamping part. The two ends of the return spring are connected to the connecting shaft and the other end of the transmission rod, respectively.

[0073] The packaging includes, but is not limited to, various items that function as containers or storage containers, such as garbage bags, shopping bags, and films. The wrapping edge refers to the opening of the garbage bag, or the overlapping edge of the film after the target item is picked up. Taking a garbage bag or film as the packaging and garbage as the target item, the usage process of the aforementioned clamping drive component 1 and clamping component 2 is as follows:

[0074] First, the operator places their palm on the handle and pulls the pull ring with their fingers, lifting the transmission rod, which in turn pulls the first and second swing arms. The rotating connection redirects the upward pulling force, driving the first and second clamping parts to rotate in opposite directions, thus opening the clamps. Simultaneously, the return spring is stretched as the transmission rod moves.

[0075] Then, the operator moves the clamping end so that the garbage falls between the first clamping part and the second clamping part; at this time, the pull ring is released, and the reset spring resets while driving the transmission rod to move downward. The first swing arm and the second swing arm are pushed, which in turn drives the first clamping part and the second clamping part to rotate in a direction that moves closer to each other, so that the clamps are clamped; at this time, the garbage is collected into the internal space formed by the first clamping part and the second clamping part or is clamped by the first clamping part and the second clamping part.

[0076] Please refer to Figure 3 and Figure 4 Embodiment two of this utility model is as follows:

[0077] A gripping device, based on the above embodiment 1, wherein the gripping end of the gripping component 2 is provided with a first pressure plate 212 and a second pressure plate 200 opposite to each other; a sealing component 21 is provided on the first pressure plate 212 and / or the second pressure plate 200.

[0078] In this embodiment, it should be noted that,

[0079] In this embodiment, a first pressure plate 212 and a second pressure plate 200 are respectively installed on the first clamping part and the second clamping part. When the clamping end of the clamping assembly 2 clamps the two sides of the opening of the garbage bag, the first pressure plate 212 and the second pressure plate 200 also move closer to each other as the clamping action proceeds, which can press the two sides of the opening of the garbage bag together. At the same time, the sealing assembly 21 also comes into contact with the garbage bag and causes the garbage bag to be sealed.

[0080] Optionally, the sealing component 21 can be a heat-sealing component for the aforementioned sealing function. The first pressure plate 212 and the second pressure plate 200 tightly adhere the two sides of the garbage bag's film together, while the heat-sealing component is positioned on the side of the garbage bag where the first pressure plate 212 or the second pressure plate 200 presses against it. After being heated to 120°C to 180°C, the heat-sealing component, the first pressure plate 212, and the second pressure plate 200 work together, using external heat and pressure to melt and fuse the contact surfaces of the two plastic films, which then solidify upon cooling into a strong, integrated sealed interface.

[0081] The gripping device of this embodiment has at least the following two uses:

[0082] The first scenario involves using a garbage bag: A garbage bag is placed over the first and second clamping parts, allowing the entire clamping assembly 2 to grip the garbage with the bag attached. When the first and second clamping parts are in a clamping state, the garbage bag is controlled to wrap around the garbage. At this time, the sealing assembly 21 seals the edges of the garbage bag covering the garbage. After sealing, the gripping device is moved above the garbage bin, releasing the clamping assembly 2, and the garbage bag naturally falls into the garbage bin. For greater convenience, the clamping drive assembly 1 has a storage compartment for storing garbage bags. When a garbage bag is needed, it can be pulled out from the opening of the storage compartment.

[0083] The second scenario involves using a film: First, a film is placed over the trash, ensuring complete coverage, ideally with the trash positioned below the center of the film. Then, the first and second gripping parts of the gripping device are controlled to grip the trash from above the film cover. It's worth noting that this method applies to gripping devices where the first and second gripping parts are box-shaped or lid-shaped, as shown in the diagram. During gripping, the entire film gradually wraps around the trash. The first pressure plate 212 and the second pressure plate 200 also press the edges of the film wrapping. The sealing assembly 21 seals the edges of the trash bag wrapping the trash. After sealing, the gripping device is moved above the trash can, the gripping assembly 2 is released, and the trash bag wrapping the trash falls naturally into the trash can.

[0084] It should be noted that, for environmentally friendly design purposes, both the garbage bags and films in this embodiment can be made of biodegradable materials.

[0085] Please refer to Figure 3 and Figure 4 Embodiment three of this utility model is as follows:

[0086] A gripping device, based on the above embodiment one or two, includes at least two long strips of plates that form a semi-enclosed structure, with the first pressure plate 212 and the second pressure plate 200 each having a sealing component 21; when the clamping end of the clamping component 2 clamps the two sides of the opening of the garbage bag, the long strips of the first pressure plate 212 and the long strips of the second pressure plate 200 correspond one-to-one to press the wrapping edge of the package.

[0087] In this embodiment, the long strips at different positions are used to clamp the garbage bag around different sides of the garbage. As shown in the figure, the first pressure plate 212 and the second pressure plate 200 adopt a contoured structure adapted to the clamping end of the clamping component 2. The clamping end of the clamping component 2 is cap-shaped or box-shaped. As shown in the figure, when the clamping end of the clamping component 2 is "U"-shaped, the first pressure plate 212 and the second pressure plate 200 can be composed of three long strips forming a "U" shape; similarly, when the clamping end of the clamping component 2 is an arc shape close to a semicircle, the first pressure plate 212 and the second pressure plate 200 can be arc-shaped plates with the same curvature. There is no limitation here.

[0088] Please refer to Figure 3 and Figure 4 Embodiment four of this utility model is as follows:

[0089] A gripping device, based on the above-described embodiments two or three, wherein the sealing assembly 21 includes a power supply module, a switch 210, and a heating wire 211; the heating wire 211 is laid on a first pressure plate 212, and a clamping member opposite to the heating wire 211 is provided on a second pressure plate 200; the power supply module and the switch 210 are both disposed at the clamping end of the gripping assembly 2, the positive output of the power supply module is connected to one end of the heating wire 211 through the switch 210, and the negative output of the power supply module is connected to the other end of the heating wire 211.

[0090] As shown in the figure, the sealing assembly 21 also includes a pressure block 213; the switch 210 is a normally open push-button switch, and the pressure block 213 is disposed opposite to the switch 210; when the clamping end of the clamping assembly 2 clamps both sides of the opening of the garbage bag, the pressure block 213 can abut against the switch 210. Furthermore, the position of the pressure block 213 is adjustable in the direction of approaching or moving away from the switch 210.

[0091] The heat-sealing function of the gripping device in this embodiment is implemented as follows:

[0092] When the first pressure plate 212 and the second pressure plate 200 press the garbage bag together, the heating wire 211 adheres tightly to the garbage bag under pressure. The power supply module supplies power to the heating wire 211, causing it to reach 120°C to 180°C within a predetermined time, which is the temperature required to heat-seal the garbage bag. Specifically, when the heating wire 211 is laid on the first pressure plate 212, a high-temperature resistant silicone sealant can be applied to the second pressure plate 200. This high-temperature resistant silicone sealant presses the garbage bag firmly onto the heating wire 211, improving the sealing effect.

[0093] In this embodiment, the clamping end of the clamping assembly 2 is provided with a mezzanine space, and the power supply module is located in the mezzanine space. The first pressure plate 212 and the first clamping part, as well as the second pressure plate 200 and the second clamping part, are detachably connected.

[0094] In summary, this utility model provides a gripping device, the core of which lies in integrating gripping and heat-sealing functions into one unit. This gripping device mainly features a tightening component on the gripping end of the clamping assembly, and a sealing component on the tightening component and / or the packaging. When the clamping drive assembly drives the gripping end of the clamping assembly to control the packaging to wrap and pick up the target, the tightening component tightens the edges of the packaging, and the sealing component seals the edges of the packaging. This avoids the hassle of manually tying bags, and the sealed garbage bag effectively prevents odor emission and bacterial contamination, making it more hygienic and convenient. A heating wire is used as the heat-sealing element, along with a power supply module and a normally open push-button switch triggered by a pressure block. This design achieves automatic control of "powering on when clamped and cutting off when released," which is simple to operate, energy-efficient, and the mechanical triggering method effectively prevents misoperation and improves safety.

[0095] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
