[0036] The following refers to Figures 1-6 The box body 100 according to the embodiments of the utility model is described.

[0037] Embodiment one

[0038] As Figure 1 shown, the embodiment provides a box body 100. The box body 100 comprises a first shell 1, a second shell 2 and a detachable structure 3. The first shell 1 has an inner cavity 11 and a mounting port 12, the mounting port 12 communicates with the inner cavity 11, and the second shell 2 can be mounted in the inner cavity 11 of the first shell 1 through the mounting port 12. The second shell 2 has a mounting cavity 21 therein, and an adhesive structure 22 is arranged in the mounting cavity 21, which can fixedly connect a powder block. The detachable structure 3 comprises a spring buckle 31 and a clamping groove 32, the spring buckle 31 is arranged in the inner cavity 11 and the clamping groove 32 penetrates through the second shell 2, and the spring buckle 31 is detachably mounted in the clamping groove 32.

[0039] It can be seen from the technical scheme that the embodiment provided by the utility model has the following advantages:

[0040] (1) The adhesive structure 22 can fixedly connect the powder block, and the powder block and the second shell 2 are connected and fixed through the adhesive structure 22. When it is necessary to replace the powder block, the second shell 2 is taken out from the inner cavity 11 of the first shell 1 through the mounting port 12, and the spring buckle 31 is disengaged from the clamping groove 32; then the powder block to be replaced and the second shell 2 are mounted into the inner cavity 11 of the first shell 1 through the mounting port 12. Thus, the first shell 1 and the second shell 2 are detachably assembled through the spring buckle 31 and the clamping groove 32, and when it is necessary to replace the powder block, only the second shell 2 needs to be discarded, and the first shell 1 can be continuously used, thereby reducing the waste of materials and being conducive to environmental protection.

[0041] (2) The clamping groove 32 is arranged at intervals with the adhesive structure 22, so that a space distance is formed between the adhesive area and the clamping groove 32 area, the possibility of the adhesive flowing directly into the clamping groove 32 before curing is reduced, interference between the detachable structure 3 and the adhesive structure 22 is avoided, the spring buckle 31 and the clamping groove 32 can be quickly plugged and locked, the difficulty of disassembly or structural failure caused by adhesive residue is avoided, and the convenience and reliability of the detachable assembly of the first shell 1 and the second shell 2 are improved.

[0042] As Figure 2 shown, in one specific example, the detachable structure 3 comprises a plurality of, and the plurality of detachable structures 3 are arranged at intervals along the circumferential direction. The adhesive structure 22 is arranged on the radially inner side or the radially outer side of the area surrounded by the detachable structure 3.

[0043] In one specific example, at least part of the first shell 1 and the second shell are transparent structures. The cartridge 100 of the present application can realize the replacement of the second shell 2 and the powder block through a simple buckle structure. The cartridge 100 has the same cost and size as the conventional non-replaceable cartridge 100, without cost increase. The replacement of the second shell 2 and the powder block can be easily realized through simple operation. Moreover, the internal structure is simple, the shell is designed to be transparent, which does not affect the appearance, and meets the market demand.

[0044] It should be further noted that the detachable buckle structure of the present application can be made of MABS (transparent ABS, methyl methacrylate-acrylonitrile-butadiene-styrene copolymer) or ABS (acrylonitrile-butadiene-styrene copolymer) or PETG (poly(ethylene terephthalate-co-1,4-cyclohexylene dimethylene terephthalate), polyethylene terephthalate copolymer) and other materials, without the need to use rubber magnetic and iron plate magnetic attraction method, avoiding the potential pollution of existing iron plate anti-rust spraying to the material body.

[0045] Embodiment two

[0046] As shown in Figure 1 Further, the bonding structure 22 is arranged on the cavity bottom wall surface 2111 of the mounting cavity 21, and the bonding structure 22 is specifically located in the middle region of the cavity bottom wall surface 2111. The clamping groove 32 penetrates the cavity bottom wall 211 of the mounting cavity 21, and the clamping groove 32 is arranged on the radial outer side of the bonding structure 22, i.e. the clamping groove 32 is arranged on the radial outer side of the middle region. Specifically, when bonding the powder block and the second shell 2, an appropriate amount of adhesive needs to be filled in the middle region of the cavity bottom wall surface 2111 of the second shell 2, and then the powder block is bonded to the cavity bottom wall surface 2111, or the adhesive is filled on the bottom of the powder block, and then the powder block is bonded to the cavity bottom wall surface 2111. However, when the powder block contacts the cavity bottom wall surface 2111, the adhesive flows in an undirectional manner, and the adhesive may overflow the bottom edge of the powder block. By arranging the clamping groove 32 on the radial outer side of the bonding structure 22, the clamping groove 32 region is more difficult to be affected due to being far from the center, which is beneficial to avoid interference between the detachable structure 3 and the bonding structure 22, and further improve the convenience and reliability of the detachable assembly of the first shell 1 and the second shell 2.

[0047] As shown in Figure 2 and Figure 3As shown, further, the cavity bottom wall surface of the mounting cavity 21 is also provided with an anti-overflow groove 212, which is specifically a groove recessed downward from the upper surface of the cavity bottom wall 211, and the anti-overflow groove 212 is annularly arranged on the bonding structure 22. By arranging the anti-overflow groove 212, it is beneficial to position the filling and coating area of the adhesive on the second shell 2; at the same time, the anti-overflow groove 212 forms an annular isolation belt, which can intercept the diffusion path when the adhesive overflows, thereby avoiding the adhesive flowing directly to the clamping groove 32.

[0048] As shown in Figure 3 and Figure 4 As shown, further, the height interval between the free end of the elastic buckle 31 and the cavity bottom wall surface 2111 of the mounting cavity 21 is H, wherein, Specifically, when the elastic buckle 31 is assembled to the clamping groove 32, part of the elastic buckle 31 is located in the clamping groove 32, the free end of the elastic buckle 31 is located in the clamping groove 32, and the free end of the elastic buckle 31 has a certain interval with the cavity bottom wall surface, and the interval distance can be 0.3mm, 0.35mm, 0.37mm, 0.4mm, 0.45mm, 0.48mm, 0.5mm, etc., which will not be listed one by one here, and the interval distance H only needs to be between 0.3mm and 0.5mm. Thus, the detachable structure 3 and the bonding area are spaced apart in height, the elastic buckle 31 is 0.3mm-0.5mm lower than the cavity bottom wall surface (i.e. the surface where the bonding structure 22 is located), which is beneficial to reduce the possibility of the adhesive sticking to the buckle foot, and is beneficial to the stability and reliability of the replacement function.

[0049] As shown in Figure 4 As shown, further, the clamping groove 32 is configured as a stepped groove, and the clamping convex on the elastic buckle 31 abuts against the step 321 of the stepped groove. Specifically, the clamping convex is provided with a slope, and the slope abuts against the step 321 to clamp the clamping groove 32.

[0050] It needs to be further explained that the stepped groove is a groove-shaped structure opened on the second shell 2, which has multiple steps (similar to a "stepped" cross section) for accommodating the free end of the elastic buckle 31. The free end of the elastic buckle 31 refers to the movable part of the elastic buckle 31, which is used to be inserted into the stepped groove of the second shell 2 and clamped on the step 321. Correspondingly, the elastic buckle 31 has a fixed end, which is the fixed part of the elastic buckle 31, and is rigidly connected with the cavity wall of the inner cavity 11 of the first shell 1. The free end is inserted into the stepped groove from the bottom of the second shell 2, and slides through the multiple steps by elastic deformation, and finally clamps on the step 321. The fixed end remains stationary and provides a reaction force to generate an elastic restoring force for the free end, thereby achieving clamping.

[0051] Furthermore, in some specific examples, the height of the spring clip 31 is 2mm to 4mm. That is, the distance from the fixed end to the free end is 2mm to 4mm. The spring clip 31 includes a spring arm and a latching protrusion. The spring arm includes a fixed end and a free end, and the latching protrusion is connected to the free end of the spring arm. The thickness of the spring arm is 0.9 to 1.2mm, and it can be made of MABS (transparent ABS, methyl methacrylate-acrylonitrile-butadiene-styrene copolymer), ABS (acrylonitrile butadiene-styrene copolymer), or PETG (poly(ethylene terephthalate-co-1,4-cyclohexylenedimethylene terephthalate copolymer) material.

[0052] Example 4

[0053] Based on Embodiment 3, this embodiment has a recessed groove 14 formed on the bottom wall of the inner cavity 11.

[0054] like Figure 4 As shown, further, a recessed groove 14 is formed in the bottom wall of the inner cavity 11. The recessed groove 14 is specifically constructed as a groove structure formed by recessing downward along the surface of the bottom wall of the inner cavity 11. The fixed end of the spring clip 31 is connected to the bottom wall of the recessed groove 14. The bottom wall of the recessed groove is lower than the original plane of the bottom wall of the inner cavity 11. By setting the spring clip 31 as a whole to be lower than the plane where the adhesive is located, the height of the spring clip 31 is avoided, thereby improving the reliability of the detachable function.

[0055] like Figure 1 As shown, further, the mounting port 12 is opened at the top of the first housing 1, and the bottom wall of the inner cavity 11 is provided with a first through port 13. The recess 14 is arranged around the first through port 13, and the spring buckle 31 is radially spaced from the outer edge of the recess 14. Specifically, when the second housing 2 is removed from the first housing 1, the second housing 2 is pushed upward through the first through port 13, and the second housing 2 exits the inner cavity 11 through the mounting port 12. When the second housing 2 is installed into the inner cavity 11 of the first housing 1, the spring buckle 31 corresponds to the position of the slot 32 and is locked in the slot 32. Since the installation position of the spring buckle 31 on the bottom wall of the recess 14 maintains a certain distance from the outer edge of the recess 14, an elastic deformation space is formed for the spring buckle 31. In conjunction with the above embodiments, the thickness and height of the recess 14 and the spring buckle 31 are matched to ensure that the spring buckle 31 has sufficient elasticity, ensuring that the feel and fastening strength of the installation and ejection of the slot 32 meet the usage requirements. This structure also helps the elastic fastening to have a certain buffering effect when subjected to impact, further reducing the risk of breakage and detachment.

[0056] Preferably, the snap fastener 31 is attached to the inner edge of the sink.

[0057] As shown in Figure 5 , further, the size of the mounting port 12 gradually decreases from the direction of the first through port 13; the second shell 2 further comprises a limiting plate 23 connected to the outer surface of the side peripheral wall of the mounting cavity 21, the limiting plate 23 has the same profile as the mounting port 12, and the size of the limiting plate 23 is larger than that of the mounting port 12 to form an interference fit. That is to say, the mounting port 12 gradually narrows from the opening to the first through port 13, which means that the mounting port 12 is a tapered structure. The limiting plate 23 is connected to the second shell 2 and has the same shape as the mounting port 12, but the size is larger, so when the two are matched, the limiting plate 23 will be pressed into the mounting port 12 to form an interference, thereby fixing the first shell 1 and the second shell 2. Thus, the mounting port 12 is tapered / ladder 321-shaped from the opening end to the first through port 13, forming a natural guide slope, which is beneficial to improve the convenience of assembly.

[0058] As shown in Figure 5 , it should be noted that the mounting port 12 here refers to the assembly channel surrounded by the peripheral edge of the first shell 1, and the peripheral taper design provides 360° omnidirectional guidance to ensure automatic centering when the second shell 2 is inserted, which can reduce assembly deviation.

[0059] In combination with Figure 1 , Figure 2 and Figure 5 , further, the limiting plate 23 is connected to the outer surface of the side peripheral wall of the mounting cavity 21 to form a flange structure. The side of the limiting plate 23 facing the mounting port 12 can also be provided with a decorative area 231, which can be sprayed or engraved with decorative patterns. The flexibility in appearance design is greater, and transparent appearance can be achieved to realize the replacement of the display surface of the second shell 2

[0060] Further, the interference amount of the first shell 1 and the second shell 2 is 0.05mm~0.15mm

[0061] In combination with Figure 1 , Figure 5 and Figure 6As shown, further, the inner cavity 11 is further provided with a first limiting portion 111, which is located between the mounting opening 12 and the first through opening 13. The first limiting portion 111 here can be configured as an annular stepped structure, and an upper and lower limiting ring 1112 is arranged on the stepped surface 1111 of the annular step, and the upper and lower limiting ring 1112 protrudes from the stepped surface 1111. The first limiting portion 111 here is configured as an annular step arranged on the inner cavity wall, and the upper and lower limiting ring is arranged on the stepped surface of the annular step, and the ring diameter of the upper and lower limiting ring is 0.2mm-0.35mm, and the height is 0.1mm-0.2mm. By arranging the first limiting portion 111, the first limiting portion 111 can be arranged from the bottom of the supporting limiting plate 23, which can improve the strength of the supporting and limiting structure, and improve the stability and reliability; at the same time, by arranging the upper and lower limiting ring 1112 on the stepped surface 111 of the annular step, the upper and lower limiting ring 1112 directly contacts the lower surface of the limiting plate 23 after the second shell 2 is inserted in place, which is conducive to avoiding the up-and-down movement of the limiting plate 23, and on the other hand, by limiting the size of the upper and lower limiting ring 1112 to a ring diameter of 0.2mm-0.35mm and a height of 0.1mm-0.2mm, the height of the upper and lower limiting ring can not only provide sufficient limiting force, but also avoid excessive hindering assembly. When the assembly error is large, the upper and lower limiting ring 1112 can absorb the error through plastic deformation or elastic deformation, ensuring that the second shell 2 is smoothly inserted in place. In normal assembly, the slight protrusion of the upper and lower limiting ring 1112 can provide rigid support to prevent the limiting plate 23 from loosening.

[0062] In combination Figure 1 and Figure 5 As shown, further, the box body 100 further comprises a cover body 4 for covering the mounting opening 12 of the first shell 1; the cover body 4 is provided with a second limiting portion 41, which abuts against the upper surface of the limiting plate 23 when the cover body 4 covers the mounting opening 12. The second limiting portion 41 here can be configured as an annular protrusion, a step or a rib structure, which directly contacts the upper surface of the limiting plate 23. Therefore, the second limiting portion 41 can press down the limiting plate 23, so that the second shell 2 is pressed down as a whole until the lower surface of the limiting plate 23 contacts the first limiting portion 111.

[0063] In combination Figure 1 and Figure 5As shown, further, the second limiting portion 41 is integrally formed on the circumferential edge of the cover body 4. The second limiting portion 41 is configured as a thickened area of the circumferential edge of the cover body 4 to increase the thickness of the side circumferential wall of the cover body 4. When the cover body 4 covers the mounting port 12, the circumferential edge of the cover body 4 abuts the circumferential edge of the mounting port 12, the second limiting portion 41 is located radially inward of the mounting port 12, and the circumferential end surface of the second limiting portion can abut the upper surface of the limiting plate 23 to press the limiting plate 23 downward, thereby enabling the limiting plate 23 to be pressed downward from 360°, and improving the stability and reliability of the assembly between the limiting plate 23 and the mounting port 12.
