Description

Technical Field

[0001] This application relates to the field of daily necessities technology, and more specifically, to a heat-melting device and a storage bucket. Background Technology

[0002] Currently, trash cans are one of the most common household items. To keep trash cans clean, people usually put trash bags inside them, throw the trash into the trash bags, and once the trash bags are full, they can lift the trash bags to throw away all the trash in the trash can.

[0003] After the garbage bag is lifted from the garbage can, it is usually open, which can easily cause garbage to leak out. To solve this problem, related technologies have installed a heat-sealing structure inside the opening of the garbage can. When the heat-sealing structure moves, it closes the garbage bag and heat-seales it, thereby preventing garbage from leaking out of the garbage bag.

[0004] However, the thermoplastic structure requires electricity to operate. It is typically connected to a wire, with one end connected to the structure and the other to a power source. During movement of the thermoplastic structure, the wire connected to the structure moves with it, while the wire connected to the power source remains stationary. This causes the wire to bend, leading to wear and a relatively short lifespan. Furthermore, excessive movement of the wire with the structure may damage the connection, preventing it from supplying power and affecting the thermoplastic function of the trash can. Summary of the Invention

[0058] In order to illustrate the technical solutions described in the present application, the following will be described in detail in combination with specific drawings and embodiments.

[0059] First embodiment

[0060] As Figures 1 to 5As shown, one embodiment of the present application provides a storage barrel, including a first hot melting structure 100, a second hot melting structure 200, a first conductive contact piece 310 and a second conductive contact piece 320; wherein:

[0061] The first hot melting structure 100 includes a first hot melting part 110, and the first hot melting part 110 is electrically connected with the first conductive contact piece 310. During the movement of the first hot melting structure 100, the first hot melting structure 100 can drive the first conductive contact piece 310 to move, so that the first conductive contact piece 310 and the first hot melting structure 100 are both close to or away from the second hot melting structure 200.

[0062] The second conductive contact piece 320 is fixed at a first specified position of the storage barrel, and the second conductive contact piece 320 is connected with a power supply. That is to say, during the use of the storage barrel, the relative position of the second conductive contact piece 320 and the storage barrel is unchanged, or in other words, the second conductive contact piece 320 is relatively fixedly arranged on the storage barrel.

[0063] When the first hot melting structure 100 moves to the first specified position in the direction close to the second hot melting structure 200, the first conductive contact piece 310 contacts the second conductive contact piece 320, so that the first hot melting part 110 can perform hot melting treatment on the storage bag located between the first hot melting structure 100 and the second hot melting structure 200.

[0064] Since the second conductive contact piece 320 is connected with the power supply, after the first conductive contact piece 310 contacts the second conductive contact piece 320, power supply can be performed through the power supply. The power of the power supply is transmitted to the first conductive contact piece 310 through the second conductive contact piece 320, and is transmitted to the first hot melting structure 100 through the first conductive contact piece 310. That is to say, the operation of supplying power to the first hot melting structure 100 is realized. After the first hot melting structure 100 is powered on, it can perform hot melting treatment on the storage bag located between the first hot melting structure 100 and the second hot melting structure 200.

[0065] The hot melting treatment device provided in the embodiment can be applied to the storage barrel. The storage barrel can be used to store articles. A storage bag can be sleeved in the storage barrel. If the articles in the storage barrel need to be moved as a whole, the opening of the storage bag can be hot melted by the hot melting treatment device arranged in the storage barrel, so as to prevent the articles from leaking out of the storage bag during the movement of the whole storage bag. The storage barrel can be used as a garbage can. When the storage barrel is used as a garbage can, the storage bag sleeved in the storage barrel is a garbage bag. Before throwing garbage, the opening of the garbage bag is hot melted by the hot melting treatment device in the storage barrel, so that the opening of the garbage bag is reduced, so as to prevent the garbage from leaking out of the opening of the garbage bag during the process of throwing garbage.

[0066] Since the first hot-melt structure 100 moves towards the second hot-melt structure 200 during the hot-melt operation, the first conductive contact 310 is driven to move towards the second conductive contact 320, thus no wire is needed to be arranged between the first hot-melt structure 100 and the receiving barrel, and the wire will not be damaged by bending. In addition, since the first conductive contact 310 and the second conductive contact 320 have not contacted during the movement of the first hot-melt structure 100, the hot-melt function will not be started before the movement is completed, thus the power is saved.

[0067] Figure 8 and Figure 9 respectively show the structures of two different conductive contacts. The first conductive contact 310 can be arranged as the structure shown in Figure 8 or the structure shown in Figure 9 , and the second conductive contact 320 can be arranged as the structure shown in Figure 8 or the structure shown in Figure 9 . The first conductive contact 310 and the second conductive contact 320 can have the same structure or different structures.

[0068] as shown in Figure 8 and Figure 9As shown, in one possible implementation, the first conductive contact 310 comprises a mounting portion 351 and a contact portion 352 connected to each other, and the contact portion 352 has an included angle with the mounting portion 351. The second conductive contact 320 can be fixed on the side of the receiving barrel facing the first hot melt structure 100. The mounting portion 351 is used to connect with the first hot melt structure 100, and the contact portion 352 is used to contact with the second conductive contact 320. In this way, the mounting portion 351 can be fixed on the first hot melt structure 100 at a proper position, and the contact portion 352 is opposite to the second conductive contact 320. The contact surface of the contact portion 352 can be parallel to the contact surface of the second conductive contact 320, or the included angle between the contact surface of the contact portion 352 and the second conductive contact 320 is relatively small, so that the contact area between the contact portion 352 and the second conductive contact 320 is relatively large. The included angle between the contact portion 352 and the mounting portion 351 can be set according to actual conditions, for example, after the mounting position of the first conductive contact 310 on the first hot melt structure 100 and the mounting position of the second conductive contact 320 are selected, the included angle between the contact portion 352 and the mounting portion 351 of the first conductive contact 310 is set. The first conductive contact 310 can be made of elastic conductive material, and because the contact portion 352 has an included angle with the mounting portion 351, the contact portion 352 can elastically deform within a certain range relative to the mounting portion 351. For example, when the contact portion 352 contacts with the second conductive contact 320, the contact portion 352 is deflected to a certain extent relative to the mounting portion 351 under the action of the second conductive contact 320, which makes the contact portion 352 abut against the second conductive contact 320, so that the contact between the first conductive contact 310 and the second conductive contact 320 is more stable, thereby making the current between the first conductive contact 310 and the second conductive contact 320 more stable after conduction. Specifically, the contact surface of the contact portion 352 of the first conductive contact 310 matches the contact surface of the second conductive contact 320. That is, if the contact surface of the second conductive contact 320 is a plane, then the contact surface of the contact portion 352 of the first conductive contact 310 is also a plane; if the contact surface of the second conductive contact 320 is a curved surface, then the contact surface of the contact portion 352 of the first conductive contact 310 is also a curved surface, so that the fit between the first conductive contact 310 and the second conductive contact 320 is higher.

[0069] In another possible implementation, the first conductive contact 310 is fixed on the side of the first hot melt structure 100 facing the second conductive contact 320, and the second conductive contact 320 includes a mounting portion 351 and a contact portion 352 connected with each other and having an included angle between the mounting portion 351 and the contact portion 352. The mounting portion 351 is configured to be connected with the second hot melt structure 200, and the contact portion 352 is configured to be in contact with the first conductive contact 310. In this way, the mounting portion 351 can be fixed on the second hot melt structure 200 at a proper position, and the contact portion 352 is opposite to the first conductive contact 310, the contact surface of the contact portion 352 can be parallel to the contact surface of the first conductive contact 310, or the included angle between the contact surface of the contact portion 352 and the first conductive contact 310 is relatively small, so that the contact area between the contact portion 352 and the first conductive contact 310 is relatively large. The included angle between the mounting portion 351 and the contact portion 352 can be set according to actual conditions, for example, after the mounting position of the second conductive contact 320 on the second hot melt structure 200 and the mounting position of the first conductive contact 310 are selected, the included angle between the mounting portion 351 and the contact portion 352 of the second conductive contact 320 is set. The second conductive contact 320 can be made of an elastic conductive material, and because the mounting portion 351 and the contact portion 352 have an included angle, the contact portion 352 can elastically deform within a certain range relative to the mounting portion 351. For example, when the contact portion 352 is in contact with the first conductive contact 310, the contact portion 352 is deflected relative to the mounting portion 351 to a certain extent under the action of the first conductive contact 310, which makes the contact portion 352 abut against the first conductive contact 310, so that the contact between the second conductive contact 320 and the first conductive contact 310 is more stable, and thus the current between the second conductive contact 320 and the first conductive contact 310 is more stable after being conducted. Specifically, the contact surface of the contact portion 352 of the second conductive contact 320 matches the contact surface of the first conductive contact 310. That is, if the contact surface of the first conductive contact 310 is a plane, the contact surface of the contact portion 352 of the second conductive contact 320 is also a plane; if the contact surface of the first conductive contact 310 is a curved surface, the contact surface of the contact portion 352 of the second conductive contact 320 is also a curved surface, so that the second conductive contact 320 and the first conductive contact 310 have a higher degree of fit.

[0070] In yet another possible implementation, the first conductive contact 310 and the second conductive contact 320 each include a mounting portion 351 and a contact portion 352 connected with each other and having an included angle between the mounting portion 351 and the contact portion 352. In this way, the first conductive contact 310 is conveniently mounted on the first hot melt structure 100, and the second conductive contact 320 is conveniently mounted on the receiving barrel.

[0071] Please continue to refer to Figure 8 and Figure 9In a possible design, when the conductive contact patch (which can be the first conductive contact patch 310 or the second conductive contact patch 320) includes the mounting portion 351 and the contact portion 352, the mounting portion 351 and the contact portion 352 are connected through the inclined transition portion 353. The inclined transition portion 353 is arranged to be relatively inclined to the mounting portion 351, and the inclined mounting portion 351 and the contact portion 352 are also arranged to be relatively inclined, so as to facilitate elastic deformation and resetting of the contact portion 352 relative to the mounting portion 351. Meanwhile, the arrangement of the inclined mounting portion 351 makes the distance between the contact portion 352 and the mounting portion 351 longer, so that there is relatively larger elastic deformation space between the contact portion 352 and the mounting portion 351. As shown in FIG. 17, Figure 3 , in the first conductive contact patch 310 and the second conductive contact patch 320, the mounting portion 351 and the contact portion 352 are arranged to be relatively inclined. Figure 3 , in the first conductive contact patch 310 and the second conductive contact patch 320, the mounting portion 351 and the contact portion 352 are arranged to be relatively inclined. Figure 8 , in the first conductive contact patch 310 and the second conductive contact patch 320, the mounting portion 351 and the contact portion 352 are arranged to be relatively inclined.

[0072] As shown in FIG. 18, Figure 3 , Figure 8 , Figure 9 , in a possible design, the mounting portion 351 includes a body, and the body is provided with the elastic flange 354. The elastic flange 354 is connected to the body and arranged to be relatively inclined to the body. The elastic flange 354 can fix the mounting portion 351 in the mounting space. The first hot melt structure 100 can be provided with a support area and a limiting area, and a gap is arranged between the support area and the limiting area. The mounting portion 351 of the first conductive contact patch 310 is located between the support area and the limiting area. When the elastic flange 354 is in the initial position, the distance between the elastic flange 354 and the body is greater than the distance between the support area and the limiting area. Therefore, when the mounting portion 351 is stretched into the gap between the support area and the limiting area, the elastic flange 354 is compressed and deformed, so that the body abuts against the support area and the elastic flange 354 abuts against the limiting area, to increase the friction between the first conductive contact patch 310 and the first hot melt structure 100 and improve the installation stability.

[0073] In a possible design, the number of the elastic flanges 354 is a plurality, and the plurality of elastic flanges 354 are spaced and linearly distributed on the body. The inclined directions of adjacent elastic flanges 354 can be the same or different. The plurality of elastic flanges 354 can be spaced and distributed in the length direction or the width direction on the body.

[0074] As shown in FIG. 19, Figure 8 , two elastic flanges 354 are arranged on the body in the width direction, and the inclined directions of the two elastic flanges 354 are the same.

[0075] As shown in Figure 9 The body is provided with four elastic flanges 354, which are arranged along the length direction of the body and opposite to each other.

[0076] In one possible implementation, the mounting portion 351 on the first conductive contact 310 is in interference fit with the first hot melt structure via the elastic flange 354, so as to be relatively fixed. The mounting portion 351 on the second conductive contact 320 is in interference fit with the corresponding area on the receiving barrel via the elastic flange 354, so as to be relatively fixed.

[0077] In another implementation, to improve the installation stability, the first hot melt structure is provided with a first clamping slot. Specifically, the first clamping slot is arranged on the side of the limiting area towards the supporting area. The number of the first clamping slots is the same as that of the elastic flanges 354 on the first conductive contact 310, and the positions are opposite. When the first conductive contact 310 is installed between the supporting area and the limiting area, the elastic flange 354 extends into the corresponding first clamping slot, and the first conductive contact 310 is limited via the relative fit of the elastic flange 354 and the first clamping slot, so as to improve the installation stability of the first conductive contact 310.

[0078] Similarly, the receiving barrel is provided with a second clamping slot, which is arranged at the installation position of the second conductive contact 320 in the receiving barrel. The number of the second clamping slots is the same as that of the elastic flanges 354 on the second conductive contact 320, and the positions are opposite. When the second conductive contact 320 is installed to the receiving barrel, the elastic flange 354 extends into the corresponding second clamping slot, and the second conductive contact 320 is limited via the relative fit of the elastic flange 354 and the second clamping slot, so as to improve the installation stability of the second conductive contact 320.

[0079] As shown in Figure 9 In yet another implementation, the mounting portion 351 is provided with a mounting hole 355. In this way, a screw, a locking pin or other auxiliary installation structure can be installed via the mounting hole 355, so as to connect the first conductive contact 310 with the first hot melt structure 100, or connect the second conductive contact 320 with the receiving barrel.

[0080] In the same conductive contact, the mounting hole 355 and the elastic flange 354 can be arranged simultaneously, or only one of them can be arranged.

[0081] In one possible design, the first hot melt portion 110 is directly connected with the first conductive contact 310.

[0082] Alternatively, in another possible design, the first heat-fused part 110 and the first conductive contact 310 are electrically connected by a wire, and the first heat-fused structure 100 has a wire channel 121 for accommodating the wire. This arrangement is suitable for technical solutions where the installation positions of the first conductive contact 310 and the first heat-fused part 110 are far apart. Since both the first heat-fused part 110 and the first conductive contact 310 are located in the first heat-fused structure 100, the wire connecting the first heat-fused part 110 and the first conductive contact 310 is also located in the first heat-fused structure 100. During the movement of the first heat-fused structure 100, the wire, the first heat-fused part 110, and the first conductive contact 310 are relatively fixed, so the wire connecting the first heat-fused part 110 and the first conductive contact 310 will not be worn due to bending.

[0083] In one possible design, the first heat-fusion structure 100 includes a first movable arm 120, the first movable arm 120 having a first mounting area 123, a first heat-fusion part 110 mounted in the first mounting area 123, an end of the first movable arm 120 slidably fitted to a storage bucket, and a wire channel 121 provided between the end of the first movable arm 120 and the first mounting area 123. A first conductive contact 310 is mounted on the end of the first movable arm 120.

[0084] The first mounting area 123 can be a groove or a boss to facilitate the installation of the first hot-melt part 110.

[0085] like Figure 10 As shown, Figure 10 The first mounting area 123 of the first movable arm 120 is a groove. Part of the structure of the first hot-melt part 110 extends into the groove and is fixedly installed in the groove. This arrangement reduces the space occupied by the first hot-melt structure 100 on the one hand, and the groove limits the first hot-melt part 110 and also provides protection.

[0086] exist Figure 10 and Figure 11 In this design, a first conductive contact 310 is provided at each end of the first movable arm 120. The first mounting area 123 is located in the middle region of the first movable arm 120, such that the distance between the first mounting area 123 and the two first conductive contacts 310 on both sides is equal or similar, and the length of the wire between the two first conductive contacts 310 and the first heat-fused part 110 is consistent or similar. It is worth noting that when there are two first conductive contacts 310, there are also two second conductive contacts 320 installed on the storage bucket, with the two second conductive contacts 320 arranged opposite to the two first conductive contacts 310.

[0087] like Figure 10 and Figure 11As shown, a through hole 122 is provided in the first mounting area 123. After the first hot melt part 110 is installed in the first mounting area 123, the wire passes through the through hole 122 to the rear side of the first mounting area 123 and extends along the wire channel 121 to the mounting location of the first conductive contact 310.

[0088] The wire channel 121 can be a channel inside the first moving arm 120, or, as... Figure 11 As shown, staggered L-shaped limiting claws can be provided on the first moving arm 120, forming a wire channel 121 between the staggered limiting claws. This arrangement facilitates the installation of wires.

[0089] Second Embodiment

[0090] The hot melt processing apparatus provided in this embodiment is an improvement on the hot melt processing apparatus provided in the first embodiment, and the technical solution disclosed in the first embodiment is also included in the technical solution disclosed in this embodiment.

[0091] In the first embodiment, the first heat-melting part 110 is provided only in the first heat-melting structure 100 for heat melting, while in this embodiment, such as Figures 2-5 As shown, the second heat-melting structure 200 includes a second heat-melting part 210, and the heat-melting processing device further includes a third conductive contact 330 and a fourth conductive contact 340. The second heat-melting part 210 is electrically connected to the third conductive contact 330. During the movement of the second heat-melting structure 200, the second heat-melting structure 200 can drive the third conductive contact 330 to move closer to or away from the first heat-melting structure 100. The fourth conductive contact 340 is fixed at a second designated position of the storage bucket and is connected to a power source. When the second heat-melting structure 200 moves towards the second designated position closer to the first heat-melting structure 100, the third conductive contact 330 contacts the fourth conductive contact 340, so that the second heat-melting part 210 can perform heat-melting processing on the storage bag located between the first heat-melting structure 100 and the second heat-melting structure 200.

[0092] In other words, before the hot-melting operation is performed, the first hot-melting structure 100 and the second hot-melting structure 200 move toward each other. After they are in place, the first conductive contact 310 contacts the second conductive contact 320, and the third conductive contact 330 contacts the fourth conductive contact 340. In this way, the first hot-melting part 110 and the second hot-melting part 210 can be used together for hot-melting.

[0093] Of course, in actual use, the second conductive contact 320 can be powered to perform hot melt treatment only through the first hot melt part 110, the second hot melt part 210 only supports the storage bag; or the fourth conductive contact 340 is powered to perform hot melt treatment only through the second hot melt part 210, the first hot melt part 110 only supports the storage bag; or the second conductive contact 320 and the fourth conductive contact 340 are powered to simultaneously perform hot melt treatment on the storage bag from both sides of the storage bag through the first hot melt part 110 and the second hot melt part 210.

[0094] The structures of the third conductive contact 330 and the fourth conductive contact 340 can be set as shown in Figure 8 or Figure 9 The structures of the third conductive contact 330 and the fourth conductive contact 340 can be the same or different.

[0095] The structures of the third conductive contact 330 and the fourth conductive contact 340 can be the same as or different from the structures of the first conductive contact 310 or the second conductive contact 320.

[0096] For example, in a specific embodiment, the first conductive contact 310 and the second conductive contact 320 have the same structure, and the third conductive contact 330 and the fourth conductive contact 340 have the same structure.

[0097] All the conductive contacts include a mounting part 351 and a contact part 352 connected to each other, and the contact part 352 has an included angle with the mounting part 351. The mounting part 351 and the contact part 352 are connected through an inclined transition part 353. The inclined transition part 353 is arranged to be relatively inclined to the mounting part 351, and the mounting part 351 and the contact part 352 are also arranged to be relatively inclined. In this way, the contact part 352 can be elastically deformed and reset relative to the mounting part 351. The mounting part 351 includes a body, and an elastic flange 354 is arranged on the body. The elastic flange 354 is connected to the body and arranged to be relatively inclined to the body.

[0098] For example, the first conductive contact 310 and the second conductive contact 320 can be arranged as shown in Figure 8 Two elastic flanges 354 are arranged on the body and spaced apart in the width direction of the body, and the inclined directions of the two elastic flanges 354 are the same. The third conductive contact 330 and the fourth conductive contact 340 are arranged as shown in Figure 9 Four elastic flanges 354 are arranged on the body and spaced apart in the length direction of the body, and the inclined directions of the two adjacent elastic flanges 354 are opposite.

[0099] For example, the first conductive contact 310 and the second conductive contact 320 can be arranged as shown in Figure 13As shown, the storage barrel is provided with a support table 511 and a limiting plate, a gap is arranged between the support table 511 and the limiting plate, and the mounting portion 351 of the fourth conductive contact piece 340 is located between the support table 511 and the limiting plate. When the elastic flange 354 is in the initial position, the distance between the body and the support table 511 is greater than the distance between the support table 511 and the limiting plate. Therefore, when the mounting portion 351 is inserted between the support table 511 and the limiting plate, the elastic flange 354 is compressed and deformed, so that the body abuts against the support table 511, and the elastic flange 354 abuts against the limiting plate, so as to increase the friction between the fourth conductive contact piece 340 and the storage barrel and improve the installation stability. Further, as shown, a structural reinforcement 513 is arranged below the support table 511, and the structural reinforcement 513 improves the connection strength between the support table 511 and the fourth hot melting structure. Figure 13

[0100] A third clamping groove is arranged on the second hot melting mechanism. Specifically, the number of the third clamping grooves is the same as that of the elastic flanges 354 on the third conductive contact piece 330, and the positions are opposite. When the third conductive contact piece 330 is installed to the second hot melting mechanism, the elastic flanges 354 are inserted into the corresponding third clamping grooves, and the third conductive contact piece 330 is limited through the relative cooperation between the elastic flanges 354 and the third clamping grooves, so as to improve the installation stability of the third conductive contact piece 330.

[0101] As shown, Figure 13 A fourth clamping groove 512 is arranged on the storage barrel, and the fourth clamping groove 512 is located on the side of the limiting plate facing the support table 511. The number of the fourth clamping grooves 512 is the same as that of the elastic flanges 354 on the fourth conductive contact piece 340, and the positions are opposite. When the fourth conductive contact piece 340 is installed to the storage barrel, the elastic flanges 354 are inserted into the corresponding fourth clamping grooves 512, and the fourth conductive contact piece 340 is limited through the relative cooperation between the elastic flanges 354 and the fourth clamping grooves 512, so as to improve the installation stability of the fourth conductive contact piece 340.

[0102] As shown, Figure 12 The second hot melting portion 210 is electrically connected to the third conductive contact piece 330 through a wire, and the second hot melting structure 200 includes a second moving arm 220. The second hot melting portion 210 is installed to a second installation area of the second moving arm 220. The end of the second moving arm 220 is slidingly assembled to the storage barrel, and a wire channel 121 for accommodating the wire is arranged between the end of the second moving arm 220 and the second installation area.

[0103] The second installation area can be a groove or a boss, so as to facilitate the installation of the second hot melting portion 210.

[0104] ​For example, the second installation area is a groove, and the second hot melt part 210 is partially inserted into the groove and fixedly installed in the groove. In this way, on the one hand, the second hot melt structure 200 occupies less space, and on the other hand, the groove limits and protects the second hot melt part 210.

[0105] In Figure 12 the second moving arm 220, a third conductive contact piece 330 is arranged at each end of the second moving arm 220, and the first installation area 123 is arranged at the middle region of the second moving arm 220, so that the distance between the first installation area 123 and the two third conductive contact pieces 330 is equal or similar, and the length of the wire between the two third conductive contact pieces 330 and the first hot melt part 110 is consistent or similar. It is worth noting that when the number of third conductive contact pieces 330 is two, the number of fourth conductive contact pieces 340 installed on the receiving barrel is also two, and the two fourth conductive contact pieces 340 are arranged opposite to the two third conductive contact pieces 330.

[0106] As Figure 12 shown, a through hole 122 is arranged in the second installation area, and after the second hot melt part 210 is installed in the second installation area, the wire passes through the through hole 122 to the back side of the second installation area and extends along the wire channel 121 to the installation position of the third conductive contact piece 330.

[0107] The wire channel 121 can be a channel inside the second moving arm 220, or Figure 12 as shown, L-shaped limiting claws staggered up and down can be arranged on the second moving arm 220, and the wire channel 121 is formed between the limiting claws staggered up and down. In this way, the installation of the wire is facilitated.

[0110] In the hot melt processing device, the second conductive contact piece 320 is connected with a power supply, and specifically, the power supply can be a municipal power supply or a battery. For example, the second conductive contact piece 320 is connected with a power cord, one end of the power cord is provided with a plug, and the plug can be inserted into an external socket to obtain power supply through the socket. When the power supply is a battery, the receiving barrel further comprises a power supply box 620, the power supply box 620 is electrically connected with the second conductive contact piece 320, the power supply box 620 is fixed on the inner side or the outer side of the barrel body 600, and a battery can be installed in the power supply box 620 to supply power to the second conductive contact piece 320. A disposable battery or a rechargeable battery can be installed in the power supply box 620. When the power supply box 620 is used to install a rechargeable battery, the power supply box 620 can be provided with a charging socket, and after the charging socket is inserted into a charging cord, the charging cord can be used to charge the rechargeable battery in the power supply box 620.

[0111] When the hot melt processing device comprises a third conductive contact piece 330 and a fourth conductive contact piece 340, the fourth conductive contact piece 340 is arranged between the power supply in the same way as the arrangement of the second conductive contact piece 320 and the power supply.

[0112] As shown in Figure 17 and Figure 18 , in a possible design, the inner side of the barrel body 600 is provided with a partition plate 610, the partition plate 610 is provided with a power supply box 620, and the power supply of the hot melt processing device is installed in the power supply box 620. The partition plate 610 provides a larger installation space for the power supply box 620, and the partition plate 610 separates the power supply box 620 from the containing area in the barrel body 600 for containing articles.

Specifically, the mounting seat 400 and the barrel body 600 can be hinged or detachably connected, and the detachable connection between the mounting seat 400 and the barrel body 600 can be clamped or realized by auxiliary structures such as bolts, buckles, etc.

[0115] When the mounting seat 400 is hinged with the barrel body 600, the mounting seat 400 can be flipped outward relative to the barrel body 600; when the mounting seat 400 is detachably connected with the barrel body 600, the mounting seat 400 can be detached from the barrel body 600. The above operations can make the opening of the barrel body 600 leak out a larger area, so as to facilitate the taking out of the storage bag with a larger volume caused by more things contained in the barrel body 600. If the barrel body 600 is damaged, the user can only replace a new barrel body 600, install the original mounting seat 400 to the new barrel body 600, and continue to use the storage barrel with the hot melting function, without discarding the entire storage barrel, which is more environmentally friendly and avoids waste of materials.
