For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0041] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] See also Figure 1This embodiment provides a storage device 001 that can be used to store garbage, that is, the storage device 001 can be called a garbage storage device or a garbage can. Obviously, the storage device 001 is not limited to storing garbage, but can also be used to store items such as vegetables, fruits, nuts or parts. When the storage bag 002 of the storage device 001 is filled with enough items and needs to be replaced with a new storage bag 002, the storage bag 002 is directly closed using a sealing mechanism, and a new bag bottom is formed at the closed position. The bag mouth of the storage bag 002 is always kept open, and there is no need to manually open the bag mouth, which reduces labor intensity and is easy to use.

[0043] See also Figure 1 The storage device 001 provided in this embodiment includes a support frame 100 and a bag sealing mechanism 200. The support frame 100 is used to install the storage bag 002 and open the bag opening of the storage bag 002; the bag sealing mechanism 200 is connected to the support frame 100, and the bag sealing mechanism 200 is used to close the storage bag 002 and form the bag bottom of the storage bag 002 in the closed position.

[0044] The storage device 001 provided in this embodiment is described by taking the use of the storage device 001 for placing garbage as an example. When in use, the continuously wound storage bag 002 is placed on the support frame 100, and the bag mouth of the storage bag 002 is opened by the support frame 100, that is, the garbage can be directly loaded into the storage bag 002 from the bag mouth. After the garbage in the storage bag 002 is placed in an appropriate amount, the storage bag 002 is closed by the bag sealing mechanism 200, and then the part of the storage bag 002 containing the garbage is separated from the rest of the storage bag 002 from the closed position. The part of the storage bag 002 containing the garbage is a closed bag body, and the garbage inside is not easy to fall from the bag body, which is hygienic and environmentally friendly. The rest of the storage bag 002 installed on the support frame 100 forms a new bag bottom at the closed position, and the bag mouth always remains in a stretched state, and can be directly used. During the use of the storage bag 002, the bag opening is always in an open state, and can be used continuously for multiple times, eliminating the need to open the bag opening each time a new storage bag 002 is replaced, reducing labor intensity and providing a better user experience.

[0045] See also Figure 2 It should be noted that the continuously wound storage bag 002 refers to the unrolled storage bag 002 being wound up. Optionally, one end of the storage bag 002 along its length direction is closed to form the bag bottom, and the other end is open 136 to form an open end, and the storage bag 002 is wound from the open end to the bag bottom, and the edge of the open end is turned outward during the winding, and the bag is wound from the inside to the outside and gradually approaches the bag bottom; or the edge of the open end is folded inward, and the bag is wound from the outside to the inside and gradually approaches the bag bottom.

[0046] Furthermore, when the storage bag 002 is rolled up, the open end of the storage bag 002 is fixed on a plurality of rollers 400, the plurality of rollers 400 are sleeved outside the connection ring 300 and rotatably cooperate with the connection ring 300, and the plurality of rollers 400 are arranged at intervals along the circumference of the connection ring 300. During the use of the storage bag 002, the storage bag 002 is continuously unwound from the rollers 400. When the storage bag 002 is used multiple times and the storage bag 002 is used to the last part, the rollers 400 are exposed and engaged with the support frame 100, so as to prevent the storage bag 002 from falling off the support frame 100 directly, thereby affecting the use.

[0047] In addition, the storage device 001 may include a storage bag 002, that is, the storage bag 002 is directly installed on the support frame 100; or, the storage device 001 does not include the storage bag 002, and the storage bag 002 can be installed by the user when needed.

[0048] In this embodiment, optionally, the support frame 100 includes a support base 110, a support rod 120 and a support ring 130, wherein the support rod 120 is connected to the support base 110, and the support ring 130 is connected to the support rod 120. The support base 110 can be placed on the ground to support the entire storage device 001.

[0049] Optionally, a battery may be arranged in the support base 110, and the battery may be a rechargeable battery; in other embodiments, a plug connected to the mains may be provided on the support base 110, or a battery and a plug connected to the mains may be provided in the support base 110, and either one of them may be selected for use.

[0050] Optionally, a channel for laying a power cord is provided in the support rod 120, the battery in the support seat 110 is provided with a power cord, and the end of the power cord away from the battery is integrated with a first plug 121, and the first plug 121 is located on the support rod 120. The number of the first plugs 121 on the support rod 120 can be one or more.

[0051] Optionally, the support ring 130 is detachably connected to the support rod 120, which is convenient for replacing the support ring 130. Furthermore, the support ring 130 is a circular ring, which is convenient for processing and manufacturing, and is also convenient for use with the storage bag 002. The support ring 130 is provided with a second plug (not shown) that cooperates with the first plug 121. After the first plug 121 and the second plug are plugged in, the two are electrically connected.

[0052] It should be noted that there may be multiple first plugs 121 on the support rod 120 , and multiple support rings 130 may be installed on the support rod 120 . Each support ring 130 may be configured with a storage bag 002 , so that classified placement of garbage can be achieved.

[0053] See also Figure 3In this embodiment, optionally, the support ring 130 has a first side 131 and a second side 132 relative to each other on its axis. When in use, the first side 131 of the support ring 130 faces upward and the second side 132 faces downward, that is, garbage is put in from the first side 131 and enters the storage bag 002 installed on the support ring 130. In other words, after the storage bag 002 is installed, the bag opening of the storage bag 002 is located at the first side 131. The inner wall of the support ring 130 is provided with an annular groove 133 for placing the storage bag 002, and the annular groove 133 extends along the circumference of the support ring 130. A baffle 134 is installed on the support ring 130, and the baffle 134 is movably connected to the support ring 130. The baffle 134 has a first position and a second position. When the baffle 134 is in the first position, the baffle 134 can close part of the notch of the annular groove 133, and reserve some distance for the storage bag 002 to extend out, so as to prevent the storage bag 002 in the annular groove 133 from escaping from the notch of the annular groove 133; when the baffle 134 is in the second position, the baffle 134 does not block the notch of the annular groove 133, so as to facilitate taking the storage bag 002 out of the annular groove 133 or placing a new storage bag 002 in the annular groove 133. Furthermore, the baffle 134 is rotatably connected to the support ring 130 , and the baffle 134 can be rotated to a first position parallel to the axis of the support ring 130 , and a second position perpendicular to the axis of the support ring 130 .

[0054] See also Figure 4 In other embodiments, an opening 136 connected to the annular groove 133 can be provided on the first side 131 of the support ring 130, and a hollow cover 135 is provided on the first side 131 of the support ring 130. The hollow cover 135 is movable relative to the support ring 130 to open or close the opening 136. After the opening 136 is opened, the storage bag 002 in the annular groove 133 can be taken out or replaced with a new storage bag 002.

[0055] In this embodiment, the storage bag 002 is wound around the outside of the plurality of rollers 400, and the storage bag 002 is supported by the connecting ring 300 and is in an open state. When the storage bag 002 is placed in the annular groove 133, the surrounding of the closed end of the storage bag 002 extends out from the notch of the annular groove 133. When garbage is put into the storage bag 002 from the first side 131, the garbage causes the bottom of the storage bag 002 to move from the first side 131 to the second side 132. And because the storage bag 002 is wound around the roller 400, the roller 400 and the connecting ring 300 rotate in coordination, the storage bag 002 can drive the roller 400 to rotate relative to the connecting ring 300, and the rotation of the storage bag 002 is flexible, that is, the depth adjustment of the storage bag 002 is more convenient. When the storage bag 002 is used to the last part, the drum 400 is exposed to the external environment, and the drum 400 will not be separated from the annular groove 133 from the notch of the annular groove 133, thereby ensuring that the storage bag 002 can be used normally.

[0056] See also Fig.11 Furthermore, a plurality of rollers 400 are evenly spaced apart along the circumference of the connecting ring 300, and each roller 400 is relatively fixed to the connecting ring 300 in the extension direction of the connecting ring 300. In other words, the distance between adjacent rollers 400 does not change, so that the force on the storage bag 002 is more even, and the depth adjustment of the storage bag 002 is more convenient and reliable.

[0057] Obviously, in other embodiments, the storage device 001 may not be provided with the connecting ring 300 and the roller 400, and the continuously wound storage bag 002 may be directly placed in the annular groove 133. Alternatively, the storage bag 002 is wound outside the roller 400, and the storage bag 002 can drive the roller 400 to rotate relative to the annular groove 133, which can also achieve the depth adjustment of the storage bag 002.

[0058] In addition, the number of the drum 400 may be one or more, which is not specifically limited in this embodiment.

[0059] See also Figure 3 In this embodiment, optionally, the storage device 001 further includes a clamping mechanism 500 and a first detection mechanism 600. The clamping mechanism 500 is connected to the support ring 130 of the support frame 100, and is used to provide a clamping force and clamp the storage bag 002 located on the support ring 130, so as to limit the moving distance of the storage bag 002 relative to the support ring 130 along the depth direction of the storage bag 002, that is, to limit the moving distance of the storage bag 002 in the direction parallel to the axis of the support ring 130, so as to control the depth of the storage bag 002. The first detection mechanism 600 is in communication connection with the clamping mechanism 500, and is disposed on the support frame 100, and is used to detect whether the object located in the storage bag 002 protrudes from the bag opening of the storage bag 002.

[0060] See also Figure 6Optionally, the clamping mechanism 500 includes an active member 510, a driven member 520, a first motor 530 and an adapter 540. The active member 510 and the first motor 530 are both connected to the adapter 540, and the active member 510 and the adapter 540 are rotationally matched. The first motor 530 is used to drive the active member 510 to rotate relative to the adapter 540. The driven member 520 is connected to the support ring 130, and the driven member 520 and the active member 510 jointly define a gap for clamping the storage bag 002. The adapter 540 is slidably matched with the support ring 130 to adjust the distance between the active member 510 and the driven member 520, thereby adjusting the size of the gap for clamping the storage bag 002. When the storage bag 002 is clamped between the active member 510 and the driven member 520 , the first motor 530 can drive the active member 510 to rotate relative to the adapter 540 , thereby driving the storage bag 002 to move along its own depth direction.

[0061] In this embodiment, optionally, the active member 510 and the driven member 520 are both configured as rollers.

[0062] Optionally, the adapter 540 is installed on the second side 132, and the adapter 540 and the support ring 130 are slidably matched along the radial direction of the support ring 130, that is, the force applied to the storage bag 002 by the active member 510 and the driven member 520 is along the radial direction of the support ring 130, which is not easy to damage the storage bag 002.

[0063] Optionally, the number of the clamping mechanisms 500 can be set to multiple, and the multiple clamping mechanisms 500 are evenly spaced along the circumference of the support ring 130, so as to better clamp the storage bag 002. In addition, the adapter 540 of each clamping mechanism 500 can be configured with a linear telescopic structure, such as a cylinder, a hydraulic cylinder or a screw transmission structure, to facilitate driving the adapter 540 to slide relative to the support ring 130.

[0064] See also Figure 5Optionally, the first detection mechanism 600 includes a first control module (not shown), an infrared transmitter 610, a reflector group 620 and an infrared receiver 630. The first motor 530, the infrared transmitter 610 and the infrared receiver 630 are all communicatively connected to the first control module, and the infrared transmitter 610, the reflector group 620 and the infrared receiver 630 are all installed on the first side 131. The reflector group 620 includes a plurality of reflectors, which are arranged along the circumference of the support ring 130. When the garbage in the storage bag 002 does not protrude from the bag opening of the storage bag 002, the light emitted by the infrared transmitter is irradiated on the reflector, and is reflected by the plurality of reflectors in sequence in the form of a broken line to reach the infrared receiver. When the garbage in the storage bag 002 protrudes from the bag opening of the storage bag 002, at least one reflected line of the light emitted by the infrared transmitter is blocked, so that the infrared receiver cannot receive the light emitted by the infrared transmitter. At this time, the first control module issues a control instruction to start the first motor 530, so that the first motor 530 drives the active part 510 to rotate, drives the bottom of the storage bag 002 to move downward, that is, drives the bottom of the storage bag 002 to move from the first side 131 to the second side 132, thereby increasing the depth of the storage bag 002 until the garbage does not protrude from the bag opening of the storage bag 002.

[0065] See also Figure 3 and Figure 6 In other embodiments, the storage device 001 further includes a driving assembly 700 , which is connected to the support ring 130 and is used to drive the adapter 540 to slide relative to the support ring 130 , thereby changing the size of the gap between the active member 510 and the driven member 520 .

[0066] Optionally, the driving assembly 700 includes a second motor 710, a gear ring 720, a driving gear 730, a driving member 740 and a limiting member 750, wherein the driving gear 730 is sleeved on the output shaft of the second motor 710, the gear ring 720 is sleeved outside the driving member 740, and the second motor 710 is connected to the support ring 130 to drive the driving member 740 to rotate around an axis parallel to the output shaft of the second motor 710. The driving member 740 cooperates with the limiting member 750 to drive the adapter 540 to slide relative to the support ring 130.

[0067] See also Figure 7 Optionally, the driving member 740 is a disk, and a first through hole 741 is provided in the middle of the driving member 740. The first through hole 741 may be a cylindrical hole, and a plurality of slots 742 are provided on the hole wall of the first through hole 741. The plurality of slots 742 are arranged at intervals along the circumference of the first through hole 741, and each slot 742 has two slot walls 743 with an angle in the circumference of the first through hole 741. Optionally, the aperture of the first through hole 741 is not less than the inner diameter of the support ring 130 to prevent the storage bag 002 from contacting the driving member 740.

[0068] See also Figure 8 Optionally, the limiting member 750 has a coaxial connecting cylinder 751 and a limiting plate 752, the limiting plate 752 is provided with a second through hole 7521 and a plurality of guide grooves 7522, the second through hole 7521 may be a cylindrical hole, the aperture of the second through hole 7521 is not less than the inner diameter of the support ring 130; the second through hole 7521 is communicated with the cylinder cavity of the connecting cylinder 751. The plurality of guide grooves 7522 are arranged at intervals along the circumference of the second through hole 7521, and each guide groove 7522 extends along the radial direction of the second through hole 7521.

[0069] When the driving assembly 700, the support ring 130 and the clamping mechanism 500 provided in this embodiment are assembled, the driving member 740 is sleeved outside the connecting tube 751, and the connecting tube 751 is connected to the second side 132 of the support ring 130, and the driving member 740 and the connecting tube 751 are rotated and matched around the axis of the first through hole 741. The second motor 710 is installed on the second side 132 of the support ring 130, and the driving gear 730 is meshed with the gear ring 720 sleeved outside the driving member 740. Each slot 742 corresponds to a guide groove 7522. The adapter 540 of the clamping mechanism 500 is slidably matched with the guide groove 7522 along the extension direction of the guide groove 7522. Optionally, the guide groove 7522 can be a dovetail groove or a T-shaped groove, so as to prevent the adapter 540 from falling off from the limiting member 750. Part of the adapter 540 passes through the guide groove 7522 and then extends into the clamping groove 742 . Each adapter 540 is matched with one guide groove 7522 and one clamping groove 742 . When the second motor 710 is started, the driving member 740 is driven to rotate through the driving gear 730 and the gear ring 720. Since the adapter 540 is clamped in the slot 742, the slot wall 743 of the slot 742 abuts against the adapter 540, and the driving member 740 can drive the adapter 540 to move. At the same time, since the two slot walls 743 of the slot 742 have an angle, the force applied by the driving member 740 on the adapter 540 is decomposed into a first component force along the tangent direction of the driving member 740 and a second component force along the radial direction of the driving member 740. Since the adapter 540 is clamped in the guide groove 7522, the movement of the adapter 540 under the first component force is restricted, so that the adapter 540 can only slide along the extension direction of the guide groove 7522 under the second component force, thereby driving the active member 510 to approach or move away from the driven member 520, and finally changing the clamping force of the storage bag 002. Please refer to Figure 5, for the convenience of description, it is assumed that: when the driving member 740 rotates clockwise, the adapter 540 is driven to approach the driven member 520, thereby increasing the clamping force; when the driving member 740 rotates counterclockwise, the groove wall 743 of the slot 742 does not exert force on the adapter 540, and the clamping force is reduced. The storage bag 002 exerts an external force on the active member 510, driving the active member 510 away from the driven member 520, so that the adapter 540 is close to the groove wall 743 of the slot 742. When the adapter 540 is held by the groove wall 743 of the slot 742, the active member 510 cannot continue to move away from the driven member 520, and the active member 510 and the driven member 520 cooperate to clamp the storage bag 002.

[0070] The driving assembly 700 can simultaneously drive multiple clamping mechanisms 500 to move to adjust the clamping force, and the control is more convenient and reliable. Obviously, when there is only one clamping mechanism 500, the driving assembly 700 can also be used to drive the adapter 540 to move.

[0071] In this embodiment, optionally, the storage device 001 further includes a controller (not shown) and a pressure sensor 800, the pressure sensor 800 is connected to the support ring 130, and is used to detect the pressure applied by the storage bag 002 to the support ring 130; the controller is electrically connected to the pressure sensor 800, and the controller is used to adjust the clamping force of the clamping mechanism 500 according to the pressure information detected by the pressure sensor 800. Optionally, the second motor 710 is electrically connected to the controller.

[0072] In actual use, the clamping force of the clamping mechanism 500 clamping the storage bag 002 corresponds to the weight of the garbage stored in the storage bag 002, so as to avoid the situation where the storage bag 002 is automatically lowered due to the excessive weight of the garbage. In other words, the clamping force of the clamping mechanism 500 clamping the storage bag 002 is proportional to the weight of the garbage. When the pressure sensor 800 detects that the weight of the garbage increases, the controller generates a corresponding control signal based on the information of the pressure sensor 800 to control the second motor 710, so that the driving member 740 drives the adapter 540 to move, and the active member 510 is close to the driven member 520, so as to increase the clamping force. On the contrary, the clamping force is reduced.

[0073] In this embodiment, optionally, the pressure sensor 800 is disposed on the support ring 130 .

[0074] Optionally, the bag sealing mechanism 200 is communicatively connected with the controller, and when the pressure value detected by the pressure sensor 800 reaches a preset value, the pressure sensor 800 transmits the pressure information to the controller, and the controller generates a control signal to control the operation of the bag sealing mechanism 200, so that the bag sealing mechanism 200 seals the storage bag 002, thereby preventing the gravity of the garbage from exceeding the load-bearing limit of the storage bag 002 and damaging the storage bag 002.

[0075] See also Figure 1 ,in, Figure 1 The dotted line in the figure represents the detection line emitted by the second detection mechanism 900. In this embodiment, optionally, the storage device 001 further includes a second detection mechanism 900 connected to the support frame 100, and the second detection mechanism 900 is used to detect the volume of the storage bag 002; the second control module of the second detection mechanism 900 is electrically connected to the bag sealing mechanism 200, and when the second detection mechanism 900 detects that the volume of the storage bag 002 is greater than a preset value, the second control module controls the bag sealing mechanism 200 to move to seal the storage bag 002.

[0076] Optionally, the second detection mechanism 900 can be an infrared detection mechanism, which continuously emits infrared rays. As the volume of the storage bag 002 continues to expand, the storage bag 002 blocks the infrared rays emitted by the second detection mechanism 900. At this time, the volume of the storage bag 002 expands to match a preset value, and the second control module of the second detection mechanism 900 can control the bag sealing mechanism 200 to close the storage bag 002.

[0077] It should be noted that the controller, the first control module and the second control module can be integrated into one.

[0078] In addition, the bag sealing mechanism 200 performs the bag sealing operation when one of the two conditions is met: the weight of the garbage in the storage bag 002 exceeds a preset value and the volume of the storage bag 002 exceeds a preset value.

[0079] See also Fig. 9 and Fig.10In this embodiment, optionally, the bag sealing mechanism 200 includes a limit rail 210, a cable 220, a reset member 230, two hot melt sheets 240, and a mounting post 260. The limit rail 210 is mounted on the second side 132 of the support ring 130 through the mounting post 260. The mounting post 260 is closer to the middle of the support ring 130 than the limit member 750. The limit rail 210 is an arc-shaped rail, and the limit rail 210 is provided with an arc-shaped groove. One end of the cable 220 is fixedly connected to the limit rail 210, and the cable 220 extends along the arc-shaped groove, and the other end of the cable 220 extends out of the arc-shaped groove. The cable 220 surrounds a positioning space 221 for the storage bag 002 to pass through. The reset member 230 is connected to the cable 220 and the limit rail 210 at the same time, and the reset member 230 is used to make the cable 220 generate a movement trend of expanding the positioning space 221. One of the two hot melt sheets 240 is connected to the limit rail 210, and the other of the two hot melt sheets 240 is connected to the cable 220. When the bag needs to be sealed, the free end of the cable 220 is pulled, that is, the end of the cable 220 extending out of the arc groove is pulled to shrink the positioning space 221, thereby driving the storage bag 002 to shrink. When the storage bag 002 shrinks to close, the two hot melt sheets 240 clamp the storage bag 002 and heat-seal the storage bag 002 and fuse the storage bag 002 at the closed position, and the part containing the garbage forms a closed bag body. The garbage in the bag body is not easy to have odor and is not easy to scatter everywhere, which is environmentally friendly and hygienic. And the remaining storage bag 002 forms a bag body with a closed bottom, which can continue to be used. When the cable 220 tightens the storage bag 002 and the storage bag 002 is heat-sealed and melted, the external force applied to the cable 220 is removed, and under the action of the reset member 230, the cable 220 returns to its initial state, which will not affect the use of the storage bag 002.

[0080] Optionally, the reset member 230 is a spring. There are multiple reset members 230, and the multiple reset members 230 are arranged at intervals along the extension direction of the annular groove 133, so that the cable 220 is more evenly stressed and is easy to restore to the initial position.

[0081] Optionally, the pressure sensor 800 is disposed on the mounting column 260 and is located below the active component 510 , so that the weight information obtained by the pressure sensor 800 is more accurate.

[0082] See also Figure 5Optionally, the bag sealing mechanism 200 further includes a third motor 250, and the free end of the cable 220 is fixedly connected to the output shaft of the third motor 250. The rotation of the third motor 250 can drive the cable 220 to be wound around the output shaft of the third motor 250, and the degree of automation is high. Further, the third motor 250 is connected to the controller for communication. When the pressure sensor 800 detects that the weight of the garbage in the storage bag 002 reaches a preset value, the controller controls the third motor 250 to move, so that the cable 220 tightens the storage bag 002, thereby realizing the bag sealing operation.

[0083] Obviously, both ends of the pull rope 220 can be free ends. When in use, the two ends of the pull rope 220 are pulled at the same time to shrink the positioning space 221, so that the storage bag 002 is closed by the hot melt sheet 240.

[0084] It should be noted that the electric energy required by the first motor 530, the second motor 710, the third motor 250, the hot melt sheet 240, the pressure sensor 800, the first detection mechanism 600 and the second detection mechanism 900 provided in this embodiment can be provided by the battery in the support base 110, or by the mains. When the first plug 121 and the second plug are plugged in, a passage can be achieved.
