[0030] The invention provides a vacuum packaging device.

[0031] In the embodiment of the present invention, Figures 1 to 4 As shown, the vacuum packaging device includes a shell, a clamp, a vacuum pumping mechanism and a heating element.

[0032] In which, the shell 1 is provided with a hollow area for the garbage bag to pass vertically; the clamp is provided on the shell 1, and the garbage bag can be partially closed and clamped by the closing action of the clamping part of the clamp, and a poking part 100 is provided on the inner side of the clamping part for poking air holes in the part after the part is closed and clamped; the vacuuming mechanism 2 is provided on the shell 1, and the vacuuming mechanism 2 can vacuum the garbage bag through the air holes; the heating element is provided on the clamp, and is used to melt the part after the garbage bag is vacuumed to maintain a vacuum seal.

[0033] The technical solution of the present invention is to provide a hollow area in the shell for the garbage bag to pass vertically. After the garbage bag located in the hollow area is partially closed and clamped by the closing action of the clamping part of the clamp, the said part is poked with air holes by the poking part inside the clamping part. After the garbage bag containing the discarded cat litter is vacuumed by the vacuum mechanism in conjunction with the air holes, the garbage bag containing the discarded cat litter is melted and separated from the garbage bag body by the heating element, so that the garbage bag containing the discarded cat litter remains vacuum-sealed and vacuum packaging is achieved. Compared with the traditional method, the present invention has a simple structure, can automatically realize vacuum packaging, isolates the discarded cat litter from the outside world, and effectively solves the pollution problem caused by bacterial growth and fermentation after the discarded cat litter is stored for a long time.

[0034] Specifically, the garbage bag body used in the present invention is long and strip-shaped. When used for the first time, cat litter can be manually poured into the bag, or it can be used in conjunction with an automatic cat litter box. The automatic cat litter box automatically cleans out the waste cat litter and pours the cat litter into the lower end of the garbage bag body in the hollow area. The weight of the waste cat litter forces the lower end of the garbage bag body to move down into the hollow area. After vacuuming and fusing to seal, the vacuum-sealed packaging bag is separated, and the garbage bag body is melted to form a new lower end of the garbage bag body, which can be reused until the garbage bag body is consumed and then replenished with a new garbage bag body.

[0035] Specifically, the clamp includes a driving mechanism and the clamping part, the clamping part includes a swing arm 3 and a fixed arm 4 installed on the shell 1, the swing arm 3 can swing between a position horizontally against and separated from the fixed arm 4, and the driving mechanism is used to drive the swing arm 3 to swing.

[0036] Specifically, the swing arm 3 and the fixed arm 4 are long plate-like components. The fixed arm 4 is vertically fixed to the position of the shell 1 corresponding to the periphery of the hollow area. One end of the swing arm 3 is hinged to one end of the fixed arm 4. When the swing arm 3 swings in the direction horizontally opposed to the fixed arm 4, it can pass through the hollow area to push the part toward the fixed arm 4, thereby closing and clamping the part.

[0037] It should be noted that when the garbage bag is closed, wrinkles will be generated, so that after the part is completely clamped, the air holes can still extract air through the wrinkles. In order to better extract the air, in this embodiment, a garbage bag with multiple raised particles distributed on the surface is used. After the garbage bag is closed and clamped, the part is combined with the multiple raised particles to form a gap for air circulation, so that the air can be better extracted.

[0038] Specifically, the driving mechanism includes a rotating motor 200 (or motor) and a pull rope 5, one end of the pull rope 5 is connected to the swing arm 3, and the other end is connected to the rotating end of the rotating motor 200. When the rotating end rotates, the pull rope 5 can drive the swing arm 3 to swing.

[0039] Specifically, the rotating motor 200 is fixed on one side of the fixed arm 4, and the rotating end of the rotating motor 200 is fixed with a pulley 201 connected to the pull rope 5. When the rotating end rotates (for example, when rotating forward), the pull rope 5 can be wound around the pulley 201 or unwound (for example, when rotating reversely). The shell 1 is movably provided with a transmission wheel 202 at a position corresponding to the outer periphery of the hollow area. The transmission wheel 202 can move between a position close to the free end of the fixed arm 4 and a position away from it. The transmission wheel 202 partially contacts the pull rope 5 and can force the pull rope 5 to bend so that the pull rope 5 is located outside the hollow area. The pull rope 5 drives the swing arm 3 close to the fixed arm 4 while driving the transmission wheel 202 close to the fixed arm 4. A first tension spring (not shown) and a second tension spring (not shown) are also provided. The first tension spring is used to apply a pulling force to the transmission wheel 202 in the direction away from the fixed arm 4, and the second tension spring is used to apply a pulling force to the swing arm 3 in the direction away from the fixed arm 4, so that the clamp can automatically retract to the state where the clamping part is open.

[0040] Specifically, a guide rail 203 and a slider 204 are provided. The slider 204 can move along the guide rail 203, and the transmission wheel 202 can be pivotally mounted on the slider 204. An angle of less than or equal to 90° is formed between the swing arm 3 and the fixed arm 4. The length of the guide rail 203 is proportional to the range of the angle. The farther the slider 204 is from the fixed arm 4, the larger the angle, and the closer the slider 204 is to the fixed arm 4, the smaller the angle.

[0041] Specifically, a strip groove 300 is provided on the abutting sides of the swing arm 3 and the fixed arm 4. When the swing arm 3 and the fixed arm 4 abut against each other, the two strip grooves 300 are connected to form a accommodating space.

The cooperation between the insertion position 42 and the poking portion 100 can make it easier to poke air holes in the garbage bag.

[0044] Specifically, the poking portion 100 is cone-shaped.

[0045] Specifically, a sealing ring 400 is provided in the strip groove 300 , and the sealing ring 400 partially extends out of the strip groove 300 to form a contact portion 401 . When the swing arm 3 and the fixed arm 4 abut against each other, the two contact portions 401 elastically abut against each other to form a sealed accommodating space.

[0046] Specifically, the sealing ring 400 is preferably made of high-temperature resistant silicone or rubber.

[0047] Specifically, the heating element includes a first heating wire 6, which is provided at a position below the fixed arm 4 corresponding to the strip groove 300. After vacuuming, the first heating wire 6 can melt the position below the local corresponding air hole, thereby keeping the garbage bag vacuum-sealed.

[0048] Specifically, the heating element also includes a second heating wire 7, which is arranged at a position above the corresponding strip groove 300 of the fixed arm 4. The second heating wire 7 can be used to melt the position above the local corresponding air hole, thereby avoiding the situation where the garbage bag has air holes during the next use, resulting in the inability to vacuum and maintain a vacuum seal.

[0049] It should be noted that the first heating wire 6 and the second heating wire 7 can refer to the existing technology, and their specific structures will not be described in detail here.

A servo motor 93 (or motor) is also provided to drive the first plate-shaped member 91 and the second plate-shaped member 92 to perform the movement.

[0052] Specifically, the first plate-shaped member 91 and the second plate-shaped member 92 are linked by a gear structure 94. The servo motor 93 is vertically fixed to a position above the shell 1 corresponding to the first plate-shaped member 91. The rotating end of the servo motor 93 is fixedly connected to the first plate-shaped member 91 (the gear on it) to drive the first plate-shaped member 91 to perform a horizontal swinging motion, and at the same time drive the second plate-shaped member 92 to perform a horizontal motion through the gear structure 94, thereby closing or opening the top opening of the storage space.

[0053] Specifically, the top of the storage box 8 and the bottom of the shell 1 are locked by screws or detachably fixedly connected by a snap-fit structure.

[0054] Specifically, a sensing portion 95 is formed on the side of the first plate-shaped component 91 away from the gear structure 94, and a sensing element 96 is provided on the top of the storage box 8.
