Description

Technical Field

[0001] The utility model belongs to the technical field of sanitary equipment, and in particular relates to an automatic packaging mechanism and an intelligent waterless toilet. Background Art

[0002] There are many scenarios that require automatic packaging mechanisms, such as garbage packaging and recycling, take-out packaging and take-out, etc. Existing smart waterless toilets also require automatic packaging mechanisms to package excrement, such as the waterless toilet in a caravan disclosed in patent application CN110913735A, which is provided with an automatic packaging mechanism. The automatic packaging mechanism includes a sealing device and a heating element. The automatic packaging process is as follows: when excrement falls into the garbage bag, the sealing device first seals the garbage bag, and the heating element then melts the garbage bag, so that the packaged garbage bag is separated from the garbage bag roll.

[0003] The existing automatic packaging mechanism has the following defects: first, two closing devices are required, one closing device is used to seal the upper end of the garbage bag containing excrement, and the other closing device is used to seal the lower end of a new garbage bag to hold the next excrement, and then the garbage bag is melted by a heating element between the two seals. Therefore, the existing automatic packaging mechanism has a complex structure, a complex packaging process, and a high packaging cost; second, the plastic bag after packaging is filled with air, the volume of the plastic bag is large, and a large space is occupied, wasting space resources; third, the closing device and / or the heating element are easy to stick to the garbage bag, resulting in sealing defects or even failure.

[0004] With the development of economy and technology, the market prospect of automatic packaging is broad. Therefore, it is very necessary to overcome the defects of the above-mentioned automatic packaging mechanism and design an automatic packaging mechanism with simple structure, convenient packaging, reliability and stability. Utility Model Content

[0005] In order to solve the problems of complex structure and poor packaging quality of the packaging mechanism in the prior art, the utility model provides an automatic packaging mechanism and an intelligent waterless toilet.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows: an automatic packaging mechanism, comprising:

[0007] A hot melt assembly, the hot melt assembly comprising a hot melt base and a heating structure, the heating structure being arranged on the hot melt base;

[0008] A folding assembly, the folding assembly comprising a folding base and a pressing base, the pressing base being arranged on the folding base, a garbage bag passage being formed between the pressing base and the heating structure, the material belt of the expanded garbage bag passing through the garbage bag passage, and the folding base being driven by a folding driving member to move closer to or away from the heating structure;

[0009] And a buffer component, which is slidably sleeved on the outer periphery of the hot melt base. When the folding driving member drives the folding base to move close to the heating structure, the pressing base first contacts the buffer component, and then the pressing base contacts the heating structure. At the same time, the bag opening of the garbage bag to be heat-sealed is folded by the folding base to between the pressing base and the heating structure; the upper and lower parts of the heating structure seal the adjacent garbage bags at the same time, and the middle part of the heating structure melts the sealed garbage bags.

[0010] Preferably, the buffer assembly comprises a buffer base and an elastic member, the buffer base is slidably sleeved on the outer periphery of the hot melt base, and the elastic member is arranged between the buffer base and the hot melt base. When the garbage bag needs to be sealed and melted, the folding driving member drives the folding base to move close to the heating structure. At this time, the folding base folds the bag opening to be heat-sealed between the pressing base and the heating structure. Because the pressing base first contacts the buffer base of the buffer assembly, the bag opening to be heat-sealed is first folded between the pressing base and the buffer base. After overcoming the elastic force of the elastic member, the buffer base retreats, and the pressing base presses the folded bag opening to be heat-sealed onto the heating structure for heat sealing and melting. First, it prevents part of the bag opening from contacting the heating structure first, resulting in uneven heating, sealing defects or even failure. Second, after sealing and melting, the pressing base retreats and resets. At this time, the buffer base rebounds and resets under the action of the elastic member. The buffer base pulls off the heat-sealed bag opening to ensure that the heat-sealed bag opening is detached from the heating structure, effectively preventing the bag opening from sticking to the heating structure.

Furthermore, in this embodiment, the upper part of the turntable 82 is arranged higher than the annular groove 811, the upper diameter of the turntable 82 is larger than the diameter of the annular groove 811, and the shell 9 of the smart waterless toilet is connected to the upper part of the turntable 82; the button 831 is located on the front side of the smart waterless toilet.

[0064] The installation process of the rotating base 8 of the intelligent waterless toilet is as follows:

[0065] First, install the assembled rotating base 8 to the reserved position of the RV. Note that at this time, the turntable 82 is separated from the rotating base 8 as an independent component. After the independent turntable 82 is installed to the bottom of the shell 9 of the smart waterless toilet, the turntable 82 is installed on the rotating base 8: press the button 831, the button 831 drives the push plate 8321, the lever 8322 and the slide buckle 833 in turn, so that the two slide buckles 833 slide away from each other. At this time, the lower part of the turntable 82 can be inserted into the annular groove 811. At this time, the upper part of the turntable 82 is located above the annular groove 811, and then the button 831 is released. The button 831 is reset under the action of the first elastic reset member 834, and the slide buckle 833 is reset at the second elastic reset member. Under the action of the second elastic reset member 835, the slider 833 slides and resets close to the limit flange 821 until the slider 833 hooks the limit flange 821 to limit the axial movement and circumferential rotation of the turntable 82, and the slider 833 maintains the limit state of hooking the limit flange 821 under the action of the second elastic reset member 835, ensuring that the slider 833 is firmly hooked on the limit flange 821 and does not slip, thereby completing the convenient installation of the rotating base 8; the direction of the smart waterless toilet can be adjusted according to the actual reserved position, and the button 831 only needs to be pressed down as described above to make the slider 833 disengage from the limit flange 821. At this time, the turntable 82 can be rotated to any angle to adjust the direction of the smart waterless toilet, and then the button 831 is released to complete the direction adjustment of the smart waterless toilet.

[0066] When the user uses the smart waterless toilet to go to the toilet, the direction of the smart waterless toilet can be changed according to the user's own toilet habits. There are two ways to change the direction of the toilet. One is to directly rotate the shell 9 of the smart waterless toilet. By overcoming the resistance of the second elastic reset member 835, the shell 9 of the smart waterless toilet drives the turntable 82 to rotate to adjust the direction of the smart waterless toilet. The second elastic reset member 835 makes the turntable 82 have a certain damping when rotating, thereby improving the user's operating experience; the second is to press the button 831, so that the slider 833 is disengaged from the limiting flange 821 as described above. At this time, the turntable 82 can be rotated to any angle to adjust the direction of the smart waterless toilet, which greatly reduces the operating intensity and makes the operation more convenient. The disadvantaged groups can also operate it easily.

[0067] Embodiment 3:

[0068] like Fig.16 As shown, a smart waterless toilet is shown. The difference between this embodiment and embodiment 2 is that the rotating base 8 of the smart waterless toilet is replaced with a fixed base 8', and the shell 9 of the smart waterless toilet is connected to the fixed base 8'. The fixed base 8' has a simple structure and low cost.
