[0045] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0046] like Figure 1 and Figure 2As shown, the dust collection trash can of this embodiment mainly includes a barrel body 10, a dust collection system and a packaging system 30, wherein:

[0047] The barrel body 10 is provided with an inner cover 11 inside and a large cover 13 on top; the inner cover 11 is used to lay garbage bags to receive garbage, and the volume of the inner cover 11 is smaller than the barrel body 10, so as to form a cavity 12 between the barrel body 10 and the inner cover 11;

[0048] The dust collection system includes an air inlet duct 20, a dust and gas separation chamber 21, an exhaust duct 22 and a fan 23, wherein:

[0049] The air inlet 20 is disposed in the cavity 12 between the inner cover 11 and the barrel body 10, and the lower end thereof is a dust suction inlet 15, which is located at the lower part of one side of the barrel body 10, and the upper end of the air inlet 20 is connected to the dust and gas separation chamber 21;

[0050] The dust and gas separation chamber 21 is arranged in the large cover 13 and is located above the inner cover 11. The lower end of the dust and gas separation chamber 21 is open, and a dust and gas inlet 210 and an air outlet 211 are arranged on the side. The dust and gas inlet 210 is used to communicate with the upper end of the air inlet 20, and a filter device 212 is arranged on the air outlet 211 to intercept particles in the dust and gas entering the dust and gas separation chamber 21, so that the particles fall into the garbage bag laid in the lower inner cover 11 by their own gravity, and the air enters the exhaust duct 22 through the filter device 212;

[0051] One end of the exhaust duct 22 is connected to the air outlet 211 of the dust and gas separation chamber 21, and the other end is connected to the air inlet end of the fan 23;

[0052] The fan 23 is also disposed in the cavity 12 between the inner cover 11 and the barrel body 10 , and is located at an inner edge of one side of the lower portion of the barrel body 10 , with an air outlet end thereof being connected to the outside of the barrel body 10 .

[0053] Combination Figure 3 As shown, the packaging system 30 includes:

[0054] The closing mechanism 31 is located between the inner cover 11 and the dust and gas separation chamber 21 in terms of height, and is also located outside the opening of the garbage bag laid inside the inner cover 11, and is used to close the opening of the garbage bag;

[0055] The sealing mechanism 32 is disposed at the position where the bag opening of the garbage bag is gathered, and is used to seal the bag opening of the garbage bag.

[0056] The dust collection trash can of this embodiment has the functions of dust collection, garbage bag packing and garbage bag sealing. When vacuuming, the fan 23 runs to form a negative pressure in the cavity between the inner cover 11 and the barrel body 10. Dust and other fine garbage are sucked in from the dust collection inlet 15, and the dust-carrying airflow passes through the air inlet 20, reaches the dust and gas inlet 210, and enters the dust and gas separation chamber 21 above the inner cover 11. The dust-carrying airflow is filtered at the air outlet 211 of the dust and gas inlet 21, and dust and other garbage are blocked and finally fall into the garbage bag in the inner cover 11 below. The air passes through the filter device 212 at the air outlet 211, through the exhaust duct 22, and is drawn to the outside by the fan 23.

[0057] After the garbage bag in the inner cover 11 is full, the packaging system works, and the closing mechanism 31 closes the bag opening of the garbage bag to the sealing mechanism 32, and the sealing mechanism 32 closes the bag opening of the garbage bag. Among them, there is no special restriction on the specific assembly position of the sealing mechanism 32, and the closing mechanism 31 mainly has two states, one is the unfolding state, that is, when the garbage bag is spread out, the closing mechanism 31 surrounds the outside of the bag opening of the garbage bag; the second is the folding state, that is, the closing mechanism 31 is folded, and the bag opening of the garbage bag is folded together. During the use of the smart vacuum trash can, the user will not come into contact with dust, and when the user finally takes out the full and packaged garbage bag, there is no need to worry about dust rushing out of the garbage bag, so the user experience is good, both hygienic and convenient.

[0058] Preferably, the dust and gas separation chamber 21 is provided with a plurality of air outlets 211, which are basically evenly arranged on the side walls of the dust and gas separation chamber 21, so as to reduce the speed of the dust gas flowing out to a certain extent, which is conducive to the larger mass garbage particles falling into the garbage bag, and other smaller particles in the dust and gas mixed gas are also easy to complete dust and gas separation at the filtering device on the dust and gas separation chamber 21.

[0059] The filter device 212 is preferably filter cotton, or other filter products with relatively small pore structures, such as sponges, filter nets, etc. The specific structure of the filter device 212 is not limited in the present invention, and it is also easy for those skilled in the art to understand that the filter device 212 that can separate dust and gas in the gas carrying dust, so that the gas can pass through but the dust can be left behind, can be applied to the dust collection system of the present invention to achieve dust-gas separation.

[0060] Preferably, a first hinge part 100 is provided on an inner wall on one side of the upper part of the barrel body 10, and a first rotating shaft hole 101 is provided on the first hinge part 100; a second hinge part 130 is provided on an inner wall on one side of the large cover 13, and a second rotating shaft hole 131 is provided on the second hinge part 130; the large cover 13 and the barrel body 10 are hinged together by inserting the rotating shaft 132 into the first rotating shaft hole 101 and the second rotating shaft hole 131 at the same time. With such an arrangement, when the large cover 13 is closed, the appearance of the barrel body 10 is simple and beautiful, and the hinge part and the rotating shaft are hidden inside.

[0061] Furthermore, a small cover 14 is provided on the top of the large cover 13, and one side of the small cover 14 is also hinged to the upper part of the large cover 13, and the large cover 13 and the small cover 14 are opened or closed by flipping. The small cover 14 has a simple structure and is easy to open and close. When the dust collection trash can is used as a trash can, the small cover can be directly opened to throw the trash in. The upper end of the dust and gas separation chamber 21 is also set to be open, so that the thrown-in trash can pass through the middle of the dust and gas separation chamber 21 and fall into the trash bag in the inner cover 11.

[0062] In this embodiment, the other end of the exhaust duct 22 is preferably connected to the air inlet end of the fan 23 indirectly. A through hole 133 is provided in the middle of the rotating shaft 132. The other end of the exhaust duct 22 is connected to one end of the through hole 133 in the middle of the rotating shaft 132, and the other end of the through hole 133 in the middle of the rotating shaft 132 is connected to the cavity 12 between the inner cover 11 and the barrel body 10, and the air inlet end of the fan 23 is connected to the cavity 12 between the inner cover 11 and the barrel body 10. In this way, when the large cover 13 is turned over, the exhaust duct 22 and the rotating shaft 132 can rotate at the same time, forming a static connection, simplifying the structure, and improving the service life.

[0063] As described above, the dust collection trash can of the present invention has a dust collection function, and in addition, the dust collection trash can can also be used as a trash can. When a trash bag is placed in the inner cover 11 of the dust collection trash can, the airflow above the inner cover 11 is likely to suck the trash bag upward, which is not conducive to use, and may also suck the trash bag to the air outlet 211 of the dust air inlet 21, causing blockage.

[0064] Furthermore, the middle of the inner cover 11 is hollow, thereby forming a containing cavity 110, and a larger inlet 111 is provided on the top side of the inner cover 11. When in use, a garbage bag (not shown in the figure) is placed into the containing cavity 110 from the inlet 111 on the top side of the inner cover 11. A plurality of exhaust holes 112 are provided on the inner cover 11, so that gas can flow between the inner space of the inner cover 11 and the cavity 12 between the inner cover 11 and the inner wall of the barrel body 10. As a preferred solution, a plurality of exhaust holes 112 are provided on the side wall and the bottom surface of the inner cover 11.

[0065] When the fan 23 sucks, negative pressure is formed in the cavity 12 between the inner cover 11 and the barrel body 10, thereby keeping the garbage bag attached to the inner wall of the inner cover 11. In addition, the vacuum trash can can also realize the bag spreading function. For example, the garbage bag placed in the inner cover 11 is difficult to fully unfold automatically, and it is not easy to fit with the inner cover 11. At this time, the fan 23 is started, which is roughly the same as the vacuuming process, and negative pressure is formed between the inner cover 11 and the barrel body 10. The inner cover 11 is provided with an exhaust hole 112 connecting the inner and outer spaces thereof, so that the air between the garbage bag and the inner cover 11 is sucked out, so that the garbage bag can be unfolded and fit on the inner wall of the inner cover 11.

[0066] Combination Figure 2 and Figure 3 As shown, the packaging system 30 is installed in the large cover 13 by means of a mounting frame 33. Preferably, the closing mechanism 31 includes a plurality of rods 311 and a driving device 312. In the present embodiment, a total of four rods 311 are provided, two of which are motion rods 3110, and the other two are guide rods 3111. The four rods 311 are enclosed in a quadrilateral frame, which can then be enclosed outside the garbage bag, and one end of the two guide rods 3111 is fixedly connected together. The driving device 312 includes a second driving motor 3120 and two mutually connected synchronous belts 3121. Among them, the two synchronous belts 3121 are arranged one-to-one on the two guide rods 3111, and are transmission-connected to the second driving motor 3120. A guide hole (not shown) is provided at one end of the movement rod 3110, and one end of the two movement rods 3110 is sleeved on the outer sides of the two guide rods 3111 one by one. At the same time, the ends of the two movement rods 3110 are also connected one by one with the synchronous belts 3121 on the corresponding guide rods 3111. In addition, one of the two movement rods 3110 has a guide slot 3112 in the middle, and the other is inserted into the guide slot 3112.

[0067] The closing mechanism 31 surrounds the outer side of the bag opening of the garbage bag laid in the inner cover 11, and is in an unfolded state under normal conditions. When the closing mechanism 31 is working, the second drive motor 3120 runs, driving the two synchronous belts 3121 to rotate synchronously, thereby driving the two motion rods 3110 to move. Since the two synchronous belts 3121 rotate synchronously, the rotation directions are consistent. Obviously, in order to make the two motion rods 3110 move toward the two guide rods 3111 at the same time, the end of one of the two motion rods 3110 is connected to the inner side of the corresponding synchronous belt 3121, and the end of the other motion rod 3110 is connected to the outer side of the corresponding synchronous belt 3121, thereby realizing the closing action.

[0068] For the closing mechanism 31, other structures can also be used, such as setting a greater or lesser number of rods 311, and applying the same principle as the closing mechanism 31 to achieve the closing action. Alternatively, a closing device such as that disclosed in CN208603098U can also be used. It can be seen that the multiple rods 311 can be straight rods, arc rods, or even flexible rods, and the specific structure is not limited in the present invention. Under the traction of the driving device 312, the moving rod 3110 closes and closes the bag mouth of the garbage bag laid in the inner cover 110 to the sealing mechanism 320.

[0069] Preferably, the sealing mechanism 32 includes a fixing seat 321 and a heating wire 322. The specific structure of the sealing mechanism 32 can adopt the hot melt device disclosed in CN208603098U. One side of the fixing seat 321 is a working surface, and the heating wire 322 is fixed on the working surface of the fixing seat 321. The sealing mechanism 320 is fixed at the connection between the two guide rods 3111, the closing mechanism 310 closes the bag opening of the garbage bag to the working surface of the fixing seat 321, and the heating wire 322 generates heat and melts and seals the bag opening of the garbage bag.

[0070] Combination Figure 5-Figure 7 As shown, further, a supporting seat 135 protruding inward is fixedly connected to the inner side of the upper part of the large cover 13, and a garbage bag box 40 is also provided on the supporting seat 135, wherein the garbage bag box 40 is located between the closing mechanism 31 and the dust and gas separation chamber 21 in height, and the outer structure of the garbage bag box 40 is frame-shaped; the dust and gas separation chamber 21 is located above the garbage bag box 40, and when garbage is thrown in, the garbage passes through the middle of the dust and gas separation chamber 21 and the garbage bag box 40 and falls into the garbage bag in the inner cover 11 below.

[0071] The garbage bag box 40 is provided with a receiving cavity 41 along a circle of the box body for pre-placing garbage bags;

[0072] The box body of the garbage bag box 40 is provided with a connecting gap 42 along the box body, which is used to connect the accommodating cavity 41 in the garbage bag box 40 to the outside. The garbage bag box 40 can also be set as an openable structure, including a box body with an open top and a box cover (not shown in the figure) covering the open part of the box body, and the box body and the box cover of the garbage bag box 40 are not completely covered, but a gap is formed on the inside to allow the garbage bag to be taken out from the gap, such as a packaging box for a garbage bag without breakpoints disclosed in CN209023543U. When in use, a garbage bag (not shown in the figure) is pre-installed in the garbage bag box 40. When the full garbage bag is taken out, the garbage bag can be taken out from the garbage bag box 40 and the bag is automatically laid, which is more convenient to use.

[0073] Preferably, the garbage bag required to be laid in the inner cover 11 is defined as a unit garbage bag, and its length is set to l, and the length of the garbage bag required to be preset in the garbage bag box 40 is set to L, then the length relationship between the two is L=nl, wherein the coefficient n is greater than 1. In this case, the garbage bag preset in the garbage bag box 40 is a garbage bag without breakpoints of a longer length, and if it is cut from it, a plurality of unit garbage bags can be obtained. Therefore, in the automatic packaging process, the sealing mechanism 320 seals the upper part of the garbage bag laid in the inner cover 11, and the heating wire 322 is further heated to cut the garbage bag at the hot melt seal. After the packaged garbage bag is taken out, the cut end of the garbage bag without breakpoints preset in the garbage bag box 40 is also sealed, and there is a large amount of air between the bottom of the garbage bag without breakpoints and the inner cover 11, and the fan 23 of the dust collection system works to complete the above-mentioned bag laying step, so that the garbage bag preset in the garbage bag box 40 can be used continuously for multiple times.

[0074] Furthermore, a plurality of universal wheels 16 are provided at the bottom of the barrel body 10 to facilitate the movement of the dustbin.

[0075] Preferably, the dust suction inlet 15 is arranged at a side edge of the bottom surface of the barrel body 10, and the dust suction inlet is set to a larger opening, so that dust and other fine garbage on the ground can be cleaned during the process of moving the dust suction trash can; alternatively, the dust suction inlet 15 can also be arranged at other positions such as the side of the barrel body 10, and the dust suction inlet 15 is set to an interface structure for an external hose (not shown in the figure), so as to facilitate vacuum cleaning of other places besides the ground.

[0076] The embodiments of the present invention are only used to illustrate the present invention and do not constitute a limitation on the scope of the claims. Other substantially equivalent substitutes that can be thought of by those skilled in the art are all within the protection scope of the present invention.
