TECHNICAL FIELD

[0001] The present application relates to the technical field of pet equipment, and particularly relates to a garbage bag automatic sealing mechanism and an intelligent cat toilet. BACKGROUND

[0002] At present, intelligent cat toilets on the market are basically provided with automatic sealing mechanisms, which can automatically lay garbage bags and automatically seal and pack when the garbage is full.

[0003] The existing automatic sealing mechanism basically adopts one or two pressing rods to fold the garbage bag to one side or one corner of the opening of the garbage can, and then realizes sealing and packing through the cooperation of the sealing structure and the pressing part. Since the garbage bag is folded to one corner or one side of the opening of the garbage can during the sealing process, the garbage bag is unevenly stressed during the pulling process, causing the garbage bag to be elongated on one side and causing unnecessary waste of the garbage bag.

[0004] Therefore, it is necessary to improve the prior art to overcome the defects in the prior art. CONTENT OF THE UTILITY MODEL

[0005] In view of the above-mentioned deficiencies in the prior art, the present application provides a garbage bag automatic sealing mechanism.

[0015] In one embodiment, the projections of the sealing structure and the pressing portion onto the plane of the opening cover the geometric center of the opening.

[0016] In one embodiment, the first packing bar includes a first gathering structure for gathering the garbage bag toward the sealing structure, and the second packing bar includes a second gathering structure for gathering the garbage bag toward the pressing part.

[0023] Compared with the prior art, the advantages of this application are:

[0024] This application provides an automatic garbage bag sealing mechanism and a smart cat litter box.

[0035] Example 1

[0036] Please see Figure 1 and Figure 2 This application provides an automatic sealing mechanism for garbage bags (hereinafter referred to as the automatic sealing mechanism) in one embodiment, which is applied to smart garbage bins or smart litter boxes. This embodiment is described using a smart litter box as an example, but it should not be construed as limiting the scope of protection of this application. In this embodiment, the automatic sealing mechanism includes a top cover 10, a guide rod 20, a packing pressure rod 30, a transmission mechanism 40, and a drive motor.

[0037] The top cover 10 is used to cover the garbage collection compartment, and an opening 12 for garbage disposal is formed in the middle of the top cover 10. In a specific implementation scenario, the top cover 10 is also equipped with a garbage bag storage structure, in which garbage bags are stored. The smart cat litter box is also equipped with a fan for creating negative pressure. The air inlet of the fan is connected to the garbage collection compartment, which is used to create negative pressure in the garbage collection compartment. Under the action of negative pressure, the garbage bag is sucked out and laid inside the compartment, close to the inner wall of the compartment, thus realizing the automatic laying of the garbage bag. Cat excrement falls into the garbage bag in the compartment through the opening 12. When the excrement height reaches a certain threshold, the automatic sealing mechanism can be automatically activated to seal the garbage bag, realizing the automatic packaging of garbage. Specifically, the height of excrement can be detected by an infrared ranging sensor or by a through-beam sensor. There are many ways to detect the height of excrement, which is not the focus of this application and will not be described in detail here.

[0038] Guide rods 20 are mounted on the upper cover 10, and packing pressure rods 30 are slidably mounted on the guide rods 20. In this embodiment, there are two guide rods 20, respectively located on both sides of the opening 12, with the two guide rods 20 parallel to each other. The guide rods 20 are used to guide the sliding of the packing pressure rods 30, allowing them to slide more smoothly along parallel directions and reducing the risk of jamming. In other embodiments, more guide rods 20 may be provided, such as 3, 4, or 6, all of which are parallel to each other. The number of guide rods is not limited here.

[0039] The packing lever 30 is used to gather, clamp, and seal the garbage bag. Specifically, the packing lever 30 includes a first packing lever 31 and a second packing lever 32 sleeved on the guide rod 20. Both ends of the first packing lever 31 and the second packing lever 32 are provided with mounting holes. The guide rod 20 passes through the mounting holes of the first packing lever 31 and the second packing lever 32, and the first packing lever 31 and the second packing lever 32 can slide towards each other and away from each other along the guide rod 20. Figure 2 The diagram shows the packing lever 30 in an open position. In the open position, the first packing lever 31 is located near the left side of the opening 12 (within the left side of the opening 12). Figure 2 (Referring to the drawing orientation), the second packing lever 32 is located near the rear side of the opening 12. The distance between the first packing lever 31 and the second packing lever 32 is the packing distance. When the packing distance between the first packing lever 31 and the second packing lever 32 is at its maximum, the first packing lever 31 and the second packing lever 32 are in the extreme open position. When the first packing lever 31 and the second packing lever 32 are in contact with each other and the packing distance is zero, the first packing lever 31 and the second packing lever 32 are in the extreme sealed position (e.g., ...). Figure 4 and Figure 5 (As shown). The first packing lever 31 and the second packing lever 32 are driven to slide towards and away from each other along the guide rod 20 to move between extreme open positions that are far apart from each other and extreme closed positions that are in contact with each other.

[0040] The transmission mechanism 40 is used to move the first packing rod 31 and the second packing rod 32 between the extreme open position and the extreme closed position where they are in contact. Specifically, the transmission mechanism 40 includes a pair of pulleys 42 and a transmission belt 44 wound around the pulleys 42. The pair of pulleys 42 are disposed on the upper cover 10, located on one side of the opening 12, along the length of the guide rod 12, with the pair of pulleys 42 located at both ends of the opening 12. The transmission belt 44 is annular and wound around the pair of pulleys 42, with the two pulleys 42 as its endpoints, and has two relatively parallel sides. The first packing rod 31 and the second packing rod 32 are respectively connected to the two relatively parallel sides of the transmission belt 44. When the transmission belt 44 rotates around the pulleys 42, the movement directions of the opposite sides are opposite, thus driving the first packing rod 31 and the second packing rod 32 to move towards each other or away from each other.

[0041] Specifically, the first packing pressure bar 31 includes a first mounting structure 313, and the second packing pressure bar 32 includes a second mounting structure 323. The first mounting structure 313 is fixedly connected to the outer side of the transmission belt 44, and the second mounting structure 323 is fixedly connected to the inner side of the transmission belt 44. The first packing pressure bar 31 moves linearly as the outer side moves, and the second packing pressure bar 32 moves linearly as the inner side moves, thereby moving between the extreme open position and the extreme closed position.

[0042] The drive motor 50 provides power to the packing pressure bar 30. Specifically, the drive motor 50 is located on the upper cover 10 and is connected to one of the pulleys 42. The drive motor 50 can drive the pulley 42 to rotate forward and backward, thereby driving the transmission belt 44 to rotate forward and backward around the pulley 42, thus causing the first packing pressure bar 31 and the second packing pressure bar 32 to reciprocate between the extreme open position and the extreme sealed position.

[0043] In a specific embodiment, the transmission mechanism 40 further includes a transmission gear 43 for transmitting power from the drive motor 50 to the pulley 42. The transmission gear 43 is disposed between one of the pulleys 42 and the drive motor 50, and is used to reduce the speed of the drive motor 50 before outputting the speed. Specifically, the transmission gear 43 may include multi-stage reduction gears, and of course, the transmission gear 43 may also include planetary reduction gears, which is not limited here.

[0044] The automatic garbage bag sealing mechanism provided in this embodiment uses a drive belt to connect the first and second packing rods to opposite sides of the drive belt. A drive motor drives the drive belt to rotate forward and backward, thereby causing the first and second packing rods 31 and 32 to move towards and away from each other, reciprocating between the extreme open position and the extreme sealed position. Using a drive belt to drive the two packing rods reciprocates simplifies the drive structure and simultaneously achieves the sealing and packing of the garbage bag in the middle of the garbage bin opening. The packing process ensures even force distribution throughout, reducing garbage bag waste.

[0045] To reduce slippage of the drive belt, the inner side of the drive belt 44 is provided with internal teeth, and the pulley 42 is provided with an external toothed ring. The internal teeth of the drive belt 44 mesh with the external toothed ring of the pulley 42, thereby reducing the risk of slippage.

[0046] In a specific embodiment, the axis of rotation of pulley 42 is perpendicular to the plane where guide rod 20 is located. The drive belt is wrapped around the outside of the two pulleys 42, and the opposite sides of the drive belt 42 are parallel to guide rod 20.

[0047] For a specific embodiment, please refer to Figure 3 The first packing rod 31 has a sealing structure 315 in its middle, and the second packing rod 32 has a pressing part 325 in its middle. The sealing structure 315 and the pressing part 325 are arranged opposite to each other. When the first packing rod 31 and the second packing rod 32 are in the ultimate sealing position (see...), the sealing structure 315 and the pressing part 325 are positioned opposite to each other. Figure 5 As shown, the sealing structure and the clamping part 325 (315) abut against each other, and the garbage bag is clamped between the two. Specifically, the sealing structure 315 has a fuse (not shown) on its surface facing the clamping part 325. When the first packing lever 31 and the second packing lever 32 are detected to be in the ultimate sealing position, the fuse is energized to heat and melt the garbage bag clamped between the sealing structure and the clamping part 325 (315).

[0048] Please see Figure 6 As shown, the automatic sealing mechanism also includes a power supply wire, through which the fuse is connected to the power source. Since the first packing rod 31 reciprocates during the packing process, the fuse also reciprocates. To ensure reliable power supply to the moving fuse, one end of the first packing rod 31 is connected to a wire guide structure 46. The wire guide structure 46 is a longitudinally extending flexible structure, and the wire 70 is laid along the wire guide structure. Specifically, one end of the wire 70 is connected to the fuse, laid and fixed along the first packing rod 31, and positioned along the wire guide structure 46. Thus, during the reciprocating movement of the first packing rod 31, the wire 70 is guided and positioned by the wire guide structure 46, preventing the risk of knotting and tangling, and ensuring the reliability of the fuse's power supply.

[0049] In a specific embodiment, the wire guiding structure 46 is constructed as a chain, including multiple links connected sequentially to each other. Each link has a through hole in an aligned direction, and the wire passes through the central through hole of the link. In other embodiments, the wire guiding structure can also be constructed as a spiral conduit, with the wire passing through the spiral conduit. The spiral conduit can be stretched as the first packing rod 31 moves, and maintains a power supply connection with the fuse throughout the movement of the first packing rod 31.

[0050] Please see Figure 3 and Figure 5 , Figure 3 In the process, the first packing lever 31 and the second packing lever 32 are in an open position. The drive motor 50 rotates clockwise, causing the transmission belt 44 to rotate clockwise. The first packing lever 31 moves to the right, and the second packing lever 32 moves to the left, until the first packing lever 31 and the second packing lever 32 come into contact with each other, thus closing and sealing the garbage bag and completing the packing process. After packing, the drive motor 50 reverses, causing the transmission belt 44 to rotate counterclockwise. The first packing lever 32 moves to the left, and the second packing lever 31 moves to the right, until the maximum open position is reached, preparing for the placement of a new garbage bag.

[0051] Throughout the packing process, the first packing lever 31 and the second packing lever 33 converge from both sides of the opening 12 towards the center, thus closing the garbage bag from both sides. Please refer to [link / reference]. Figure 5 When the first packing lever 31 and the second packing lever 33 are in the ultimate sealing position, the sealing structure 315 and the clamping part 325 are located in the central area of ​​the opening 12. This ensures that the garbage bag is subjected to uniform force during the packing process, preventing one side of the garbage bag from being stretched due to excessive force, and reducing unnecessary waste. It should be noted that the central area of ​​the opening 12 should be understood as the middle 1 / 3 area along the length direction and the middle 1 / 3 area along the width direction of the opening 12. Preferably, in the ultimate sealing position, the projection of the sealing structure 315 and the clamping part 325 onto the plane of the opening 12 covers the geometric center of the opening 12.

[0052] To improve the efficiency of garbage bag sealing, please refer to the specific embodiments. Figure 2 and Figure 4The first packing lever 31 includes a first gathering structure 311 for gathering the garbage bag toward the sealing structure 315, and the second packing lever 32 includes a second gathering structure 321 for gathering the garbage bag toward the pressing part 325. The opening size of the first gathering structure 311 gradually decreases toward the sealing structure 315, allowing the garbage bag to be gradually gathered toward the sealing structure 315 during the packing process. The opening size of the second gathering structure 321 gradually decreases toward the pressing part 325, allowing the garbage bag to be gradually gathered toward the pressing part 325 during the packing process. The garbage bag is gathered between the sealing structure 315 and the pressing part 325 until the ultimate sealing position shown in Figure 4 is reached.

[0053] Specifically, the outer contours of the first gathering structure 311 and the second gathering structure 321 are basically the same, both being V-shaped. Of course, either the first gathering structure 311 or the second gathering structure 321 can also be V-shaped. The sloping edge of the V-shape helps guide the garbage bag towards the sealing structure 315 / pressing part 325, ensuring efficient gathering of the garbage bag. In other embodiments, the outer contours of the first gathering structure 315 and the second gathering structure 325 can also be semi-circular.

[0054] To ensure the best closure, please continue reading. Figure 5 As shown, when the first packing lever 31 and the second packing lever 32 are in the ultimate sealing position, the first gathering structure 311 and the second gathering structure 321 intersect each other. During the packing process, when the sealing structure 315 and the pressing part 325 have abutted, the first gathering structure 311 extends through the second packing lever 32 from the other side, and the second gathering structure 321 extends through the first packing lever 31 from the other side. The first gathering structure 311 and the second gathering structure 321 intersect each other, gathering the garbage bag to the middle area to ensure the reliability of the packing.
