Technical Field
[0001] The invention relates to the technical field of cosmetic packaging boxes, in particular to a powder box. Background Art
[0002] The loose powder box is used to hold and store loose powder for users to replenish powder.
[0003] Some loose powder boxes currently on the market usually include a box body and two transparent partition blocks installed in the box body, which divide the loose powder box into a receiving chamber and a powder outlet chamber. The two partition blocks are rotated relative to each other to realize the connectivity of the through holes on the two partition blocks, thereby realizing the connectivity between the receiving chamber and the powder outlet chamber, so that users can use loose powder.
[0004] During use, powder easily flows from the powder box into between the two partition blocks. After a period of use, the interlayer is filled with powder. On the one hand, the user has a bad visual experience, and on the other hand, the resistance encountered when rotating the cover of the powder box is too great, so improvement is needed. Summary of the invention
[0005] In order to reduce the occurrence of powder entering various places in the interlayer, the present application provides a powder box.
[0006] The above-mentioned invention objective of the present application is achieved through the following technical solutions: A powder box, comprising: A box body with an opening at one end; An isolation mechanism is arranged in the box body, and the isolation mechanism divides the inner cavity of the box body into a containing cavity for containing powder and a powder outlet cavity located at the opening side of the box body; the isolation mechanism includes a first partition block and a second partition block, and the middle part of the first partition block and the middle part of the second partition block are coaxially connected and relatively rotatable through a guide ring and a guide groove matched with the guide ring; Wherein, the first partition block has a first powder outlet cavity, the second partition block has a second powder outlet cavity, the first powder outlet cavity and the second powder outlet cavity are both located on the inner side of the guide ring; the first powder outlet cavity is provided with at least one first powder outlet hole, and the second powder outlet cavity is provided with at least one second powder outlet hole; On the rotation trajectory of the first dividing block or the second dividing block, the second dividing block has a first position relative to the first dividing block so that the at least one first powder outlet hole is correspondingly connected to the at least one second powder outlet hole, and has a second position so that the at least one first powder outlet hole is not connected to the at least one second powder outlet hole.
[0007] By adopting the above technical solution, in the first position, at least one first powder outlet hole is connected with at least one second powder outlet hole, the accommodating chamber and the powder outlet hole are connected, the loose powder can come out of the accommodating chamber, and the user can use the loose powder; when taking powder, the powder puff can be placed on the second powder outlet hole first, and then the loose powder box can be turned over after leaving a little gap, and a layer of loose powder can be taken for use. When the first powder outlet hole and the second powder outlet hole are connected, a small amount of loose powder remains in the second powder outlet hole and outside the second partition block, and may enter the first partition block and the second partition block during the subsequent rotation between the first partition block and the second partition block. However, due to the setting of the guide ring and the guide groove, the loose powder is retained on the inner side of the guide ring, that is, the middle part of the isolation mechanism, which prevents the loose powder from spreading to the outer side of the guide ring, that is, except for the middle part of the first dividing block and the second dividing block, there is no loose powder in other positions, thereby improving the overall aesthetics. Since the area where the loose powder may be retained is very small, when the first dividing block and the second dividing block are subsequently driven to rotate, the resistance to rotation is also smaller; and, when the first dividing block and the second dividing block are driven to rotate, the loose powder on the inner side of the guide ring can be gathered and refluxed into the accommodating cavity.
[0008] Preferably, a position avoidance hole is opened in the middle of the second partition block, the second powder outlet cavity is arranged around the position avoidance hole, and the at least one second powder outlet hole is connected with the position avoidance hole by opening a cavity.
[0009] By adopting the above technical solution, the avoidance hole is opened, and the second powder outlet hole is connected with the avoidance hole by opening a cavity. When in use, the powder puff is placed on the second powder outlet hole, so that the loose powder can diffuse toward the position of the avoidance hole after coming out of the second powder outlet hole, and then be more comprehensively and evenly spread on the surface of the powder puff.
[0010] Preferably, at least one sealing flange is fixedly provided on a side of the second powder outlet chamber close to the first powder outlet chamber, and the surface of the at least one sealing flange close to the first powder outlet chamber is arranged in an arc surface, and the at least one sealing flange is used to close the at least one first powder outlet hole in a one-to-one correspondence.
[0011] By adopting the above technical solution and setting the sealing flange, when the sealing flange is rotated to close the first powder outlet hole, the end of the second powder outlet chamber of the second dividing block close to the avoidance hole can be pushed outward, and then the sealing flange can be pressed against the first powder outlet hole through the restoring force of the part of the second powder outlet chamber between two adjacent second powder outlet holes, thereby achieving a tight closure.
[0012] Preferably, at least one accommodating groove is circumferentially provided on one side of the first powder outlet cavity close to the second powder outlet cavity, and the at least one accommodating groove corresponds one-to-one to the at least one blocking flange for accommodating the blocking flange.
[0013] By adopting the above technical scheme, when the sealing flange closes the first powder outlet hole, it is located at the first powder outlet hole, at this time it is the second position, and the first powder outlet hole is not connected to the second powder outlet hole; when taking powder, the first dividing block is rotated so that the sealing flange no longer closes the first powder outlet hole, and under the action of the sealing flange, the part between the two adjacent second powder outlet holes of the second powder outlet cavity is pushed outward, and the sealing flange is continued to be rotated so that the sealing flange is located at the accommodating groove, and the sealing flange is located in the accommodating groove under the action of the restoring force of the part between the two adjacent second powder outlet holes of the second powder outlet cavity, at this time it is the first position, and at this time the part between the two adjacent second powder outlet holes of the second powder outlet cavity returns to its original position and no longer has restoring force, thereby reducing the residence time of the part of the second powder outlet cavity between the two adjacent second powder outlet holes in the bending state when taking powder, and thus it is not easy to produce irreversible deformation.
[0014] Preferably, when the accommodating grooves and the first powder outlet holes are both provided in plurality, and the sealing flanges and the second powder outlet holes are correspondingly provided in plurality, the plurality of accommodating grooves and the plurality of first powder outlet holes are arranged one by one in intervals, and the plurality of sealing flanges and the plurality of second powder outlet holes are arranged one by one in intervals.
[0015] By adopting the above technical solution, the accommodating groove and the first powder outlet hole are both set to be multiple, the sealing flange and the second powder outlet hole are also correspondingly set to be multiple, and they are all arranged at intervals. When switching between the first position and the second position, one rotation can realize whether multiple first powder outlet holes and multiple second powder outlet holes are synchronously connected or not.
[0016] Preferably, the first dividing block further comprises a guide column, the first powder outlet chamber is arranged around the guide column, and the guide column passes through the avoidance hole and the rear periphery thereof is provided with a limiting flange for limiting the axial movement of the second powder outlet chamber on the guide ring.
[0017] By adopting the above technical solution, after the guide column passes through the avoidance hole, the axial movement of the second powder outlet chamber in the guide ring is limited by the limiting flange on the periphery, so that the second powder outlet chamber can rotate relative to the first powder outlet chamber, but it is difficult to separate from the first powder outlet chamber along the axial direction of the guide ring.
[0018] Preferably, the first dividing block also includes a guide column, the first powder outlet chamber is arranged around the guide column, and the guide column passes through the avoidance hole and the rear periphery is provided with a limiting flange for limiting the axial movement of the second powder outlet chamber on the guide ring, and there is a preset distance between the limiting flange and the second powder outlet chamber in the axial direction of the guide ring.
[0019] By adopting the above technical scheme, after the guide column passes through the avoidance hole, the axial movement of the second powder outlet chamber in the guide ring is limited by the limiting flange on the peripheral edge, so that the second powder outlet chamber can rotate relative to the first powder outlet chamber, but it is difficult to separate from the first powder outlet chamber along the axial direction of the guide ring, and the preset distance between the limiting flange and the second powder outlet chamber provides movement margin for the part between two adjacent second powder outlet holes of the second powder outlet chamber caused by the blocking flange to be pushed outward when the second powder outlet chamber rotates.
[0020] Preferably, a side of the first powder outlet chamber close to the second partition block is a first inclined surface, and the first inclined surface is inclined from away from the middle of the first partition block toward close to the middle of the first partition block, and from away from the second partition block toward close to the second partition block; The thickness of the second powder outlet chamber gradually increases from the middle of the second dividing block toward the middle of the second dividing block. The side of the second powder outlet chamber facing the first dividing block is a second inclined surface adapted to the first inclined surface. The second inclined surface is inclined from away from the middle of the second dividing block toward close to the middle of the second dividing block and from close to the first dividing block toward away from the first dividing block.
[0021] By adopting the above technical scheme, the first powder outlet chamber and the second powder outlet chamber are inclinedly arranged, so that the loose powder remaining between the first powder outlet chamber and the second powder outlet chamber can gradually move toward the outer edge of the inner side of the guide ring and gather, which is convenient for subsequent reflow processing; and the thickness of the second powder outlet chamber gradually thickens from close to the middle of the second dividing block toward away from the middle of the second dividing block, achieving an effect similar to that of a reinforcing rib, so that the strength of the part of the second powder outlet chamber between two adjacent second powder outlet holes is higher and it is not easy to produce irreversible deformation.
[0022] Preferably, the first dividing block is circumferentially extended toward a side close to the second dividing block to form a first extension wall, and the second dividing block is circumferentially extended toward a side away from the first dividing block to form a second extension wall, the first extension wall is located on the outside of the second extension wall, and an elastic snap ring is circumferentially provided on a side of the second extension wall close to the first extension wall, and a gap is provided between the elastic snap ring and the second extension wall; a second flange is circumferentially provided on the outer side of the elastic snap ring, and a first flange is circumferentially provided on the inner side of the first extension wall, and the first flange and the first dividing block form a groove for the second flange to be snap-fitted.
[0023] By adopting the above technical solution, the first flange on the inner side of the first extension wall and the groove formed between the first dividing block, when the second dividing block is assembled with the first dividing block along the axial direction of the guide ring, the elastic clamping ring contacts the first flange, and since there is a gap between the elastic clamping ring and the second extension wall, the elastic clamping ring can avoid the position and enter the groove through the restoring force to snap into place, thereby realizing the assembly between the first dividing block and the second dividing block, and enabling relative rotation.
[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. In the first position, at least one first powder outlet hole is connected with at least one second powder outlet hole, the accommodating chamber and the powder outlet hole are connected, loose powder can come out of the accommodating chamber, and the user can use the loose powder; when taking powder, the powder puff can be placed on the second powder outlet hole first, and then the loose powder box can be turned over after leaving a little space, and a layer of loose powder can be taken for use. When the first powder outlet hole and the second powder outlet hole are connected, a small amount of loose powder remains in the second powder outlet hole and outside the second partition block, and may enter between the first partition block and the second partition block during the subsequent rotation between the first partition block and the second partition block. However, due to the setting of the guide ring and the guide groove, the loose powder is retained on the inner side of the guide ring, that is, the middle part of the isolation mechanism, which prevents the loose powder from being scattered to the outer side of the guide ring, that is, except for the middle part of the first partition block and the second partition block, there is no loose powder in other positions, thereby improving the overall aesthetics. Because the area where the loose powder may be retained is very small, when the first partition block and the second partition block are subsequently driven to rotate, the resistance to rotation is also smaller; and when the first partition block and the second partition block are driven to rotate, the loose powder on the inner side of the guide ring can be gathered and flowed back into the accommodating cavity; 2. The avoidance hole is opened, and the second powder outlet hole is connected with the avoidance hole through the cavity. When in use, the powder puff is placed on the second powder outlet hole, so that the loose powder can spread toward the avoidance hole after coming out of the second powder outlet hole, and then spread more comprehensively and evenly on the surface of the powder puff; 3. The setting of the blocking flange can make the end of the second powder outlet cavity of the second partition block close to the avoidance hole push outward when the blocking flange is rotated to close the first powder outlet hole, and then the blocking flange is pressed against the first powder outlet hole through the restoring force of the part of the second powder outlet cavity between two adjacent second powder outlet holes, so as to achieve tight sealing; 4. When the sealing flange closes the first powder outlet hole, it is located at the first powder outlet hole, which is the second position at this time, and the first powder outlet hole is not connected to the second powder outlet hole; when taking powder, the first dividing block is rotated so that the sealing flange no longer closes the first powder outlet hole, and the portion between the two adjacent second powder outlet holes of the second powder outlet cavity is pushed outward under the action of the sealing flange, and the sealing flange is continued to be rotated so that the sealing flange is located at the accommodating groove, and the sealing flange is located in the accommodating groove under the action of the restoring force of the portion between the two adjacent second powder outlet holes of the second powder outlet cavity, which is the first position at this time, and the portion between the two adjacent second powder outlet holes of the second powder outlet cavity returns to its original position and no longer has restoring force, thereby reducing the residence time of the portion of the second powder outlet cavity between the two adjacent second powder outlet holes in the bending state when taking powder, and thus it is not easy to produce irreversible deformation.

DETAILED DESCRIPTION
[0030] The following is combined with Figure 1-4 This application is described in further detail.
[0031] The terms used in this application are only for the purpose of describing specific embodiments and are not intended to limit this application. Unless otherwise defined, the technical terms or scientific terms used in this application should be the common meanings understood by those skilled in the art to which this application belongs. The "first", "second" and similar words used in this application do not indicate any order, quantity or importance, but are only used to distinguish different components.
[0032] The powder box of the present application is described below with reference to the accompanying drawings.
[0033] The loose powder box usually includes a box body and a clamping plate assembly installed in the box body. The clamping plate assembly divides the loose powder box into a receiving chamber and a powder outlet chamber. The clamping plate assembly usually includes two transparent partitions. Through holes are provided on the two partitions. The two partitions are rotated relative to each other to realize the connection between the through holes on the two partitions, and then the connection between the receiving chamber and the powder outlet chamber is realized, so that the user can use the loose powder. However, during use, with the multiple rotations between the two partitions, the powder easily enters between the two partitions from the powder box. After a period of use, the interlayer is filled with powder everywhere. On the one hand, the user does not feel good, and on the other hand, the resistance is large during rotation.
[0034] In response to the above-mentioned problems, the present application discloses a powder box. By adding a guide ring and a guide groove in the middle part between the two dividing blocks, on the one hand, relative rotation is achieved, and on the other hand, the powder entering between the two dividing blocks is restricted to the inner side of the guide ring and the guide groove, thereby preventing the powder from entering the rest of the positions between the two dividing blocks. That is, except for the middle part of the first dividing block and the second dividing block, there is no loose powder in the rest of the positions, thereby improving the overall aesthetics. Because the area where the loose powder may remain is very small, when the rotation between the first dividing block and the second dividing block is subsequently driven, the resistance to rotation is also smaller. Moreover, when the rotation between the first dividing block and the second dividing block is driven, the loose powder on the inner side of the guide ring can gather and flow back into the accommodating cavity.
[0035] Figure 1 is a cross-sectional schematic diagram of a powder box in an embodiment of the present application, referring to Figure 1 The powder box comprises a box body 1; one end of the box body 1 is open, and an isolation mechanism 2 is arranged in the box body 1, and the isolation mechanism 2 divides the inner cavity of the box body 1 into two cavities: a receiving cavity 3 and a powder outlet cavity 4. The receiving cavity 3 is used to receive powder, such as loose powder, etc.; the powder outlet cavity 4 is located at the opening side of the box body 1, and the powder outlet cavity 4 is connected to the opening of the box body 1.
[0036] Continue to refer to Figure 1 The isolation mechanism 2 includes a first partition block 201 and a second partition block 202. The middle of the first partition block 201 and the middle of the second partition block 202 are coaxially connected and can rotate relatively to each other through a guide ring 5 and a guide groove 6 matched with the guide ring 5. Continue to refer to Figure 1 , wherein the guide ring 5 can be installed in the middle of the first dividing block 201 close to the second dividing block 202, and the guide groove 6 matching the guide ring 5 is opened in the middle of the second dividing block 202 close to the first dividing block 201; vice versa is also possible, which is not limited here.
[0037] Continue to refer to Figure 1, the first partition block 201 has a first powder outlet cavity 7, and the second partition block 202 has a second powder outlet cavity 8. Both the first powder outlet cavity 7 and the second powder outlet cavity 8 are located on the inner side of the guide ring 5, or on the inner side of the guide circular groove 6. The first powder outlet cavity 7 is provided with at least one first powder outlet hole 9, and the second powder outlet cavity 8 is provided with at least one second powder outlet hole 10. On the rotation track of the second partition block 202, there is a first position so that at least one first powder outlet hole 9 is connected with at least one second powder outlet hole 10; and there is also a second position so that at least one first powder outlet hole 9 is not connected with at least one second powder outlet hole 10. The shapes of the first powder outlet hole 9 and the second powder outlet hole 10 can be diamond, square, rectangular, circular or other shapes, etc., subject to the actual market or production demand, and the specific number of holes can also be determined according to the actual amount of powder output, which is not specifically limited here.
[0038] Continue to refer to Figure 1 It can be understood that the first dividing block 201 and the second dividing block 202 can both be used as one of the fixed ones, and the other dividing block can be used as the rotating one; or, the first dividing block 201 and the second dividing block 202 can both be used as one of the rotating ones, but the rotation angle of either one is greater than that of the other; or, one of the first dividing block 201 and the second dividing block 202 is used as the rotating one, and the other follows the same direction or the opposite direction in a driven manner. When rotating in the same direction, the angle of rotation of the driven party is smaller to achieve the relative rotation of the two in time.
[0039] Continue to refer to Figure 1 , the first partition block 201 is fixedly connected to the box body 1 as a fixed party, or connected to the box body 1 in an inserting manner so that the first partition block 201 cannot rotate, and the second partition block 202 is rotatably connected to the box body 1 to achieve relative rotation between the first partition block 201 and the second partition block 202. When the first partition block 201 or the second partition block 202 rotates to the first position, at least one first powder outlet hole 9 is correspondingly connected to at least one second powder outlet hole 10, the accommodating chamber 3 is connected to the powder outlet chamber 4, and the loose powder can come out of the accommodating chamber 3, and the user can use the loose powder.
[0040] Continue to refer to Figure 1When using it specifically, when taking powder, you can first put the powder puff on the second powder outlet hole 10, leave a little space, then turn the loose powder box over, and you can pick up a layer of loose powder for use. When the first powder outlet hole 9 and the second powder outlet hole 10 are connected, a small amount of loose powder remains in the second powder outlet hole 10 and outside the second partition block 202, and may enter between the first partition block 201 and the second partition block 202 during the subsequent rotation between the first partition block 201 and the second partition block 202. However, due to the arrangement of the guide ring 5 and the guide groove 6, the loose powder remains on the inner side of the guide ring 5, that is, the middle part of the isolation mechanism 2, which prevents the loose powder from spreading to the outside of the guide ring 5, that is, except for the first Except for the middle part of the dividing block 201 and the second dividing block 202, there is no loose powder in other positions, thereby improving the overall aesthetic feeling. Since the area where the loose powder may remain is very small, when the first dividing block 201 and the second dividing block 202 are subsequently driven to rotate, the resistance to rotation is also smaller; and, when the first dividing block 201 and the second dividing block 202 are driven to rotate, the loose powder on the inner side of the guide ring 5 can gather and flow back into the accommodating cavity 3; and the above-mentioned structure is not limited to use in the field of cosmetic packaging boxes. When other similar containers need to adopt a structure substantially the same as that of the present application to solve substantially the same problems, it should be deemed to be included in the protection scope of the present application.
[0041] Reference Figure 2 and Figure 3 In one embodiment, an avoidance hole 11 is opened in the middle of the second dividing block 202, and the second powder outlet chamber 8 is arranged around the avoidance hole 11. At least one second powder outlet hole 10 is connected with the avoidance hole 11 by opening a cavity 12. When in use, the powder puff is placed on the second powder outlet hole 10, so that the loose powder can diffuse toward the position of the avoidance hole 11 after coming out of the second powder outlet hole 10, and then be more comprehensively and evenly spread on the surface of the powder puff. When there are multiple second powder outlet holes 10, multiple second powder outlet holes 10 are circumferentially distributed on the edge of the avoidance hole 11, and each second powder outlet hole 10 is connected with the avoidance hole 11 by opening a cavity 12. The width of the cavity 12 can be consistent with the aperture size of the second powder outlet hole 10, so as to further improve the diffusion uniformity of the loose powder.
[0042] Continue to refer to Figure 2 and Figure 3 In a possible implementation, at least one blocking flange 13 is fixedly provided on a side of the second powder outlet chamber 8 close to the first powder outlet chamber 7, and the surface of the at least one blocking flange 13 close to the first powder outlet chamber 7 is arranged in an arc surface, and the at least one blocking flange 13 is used to close at least one first powder outlet hole 9 in a one-to-one correspondence.
[0043] Continue to refer to Figure 2 and Figure 3When the first powder outlet hole 9 on the first powder outlet chamber 7 is set to one, a blocking flange 13 is correspondingly provided on the side of the second powder outlet chamber 8 close to the first powder outlet chamber 7, and the blocking flange 13 and the first powder outlet chamber 7 can be integrally formed by injection molding. The blocking flange 13 can be arranged on one side of the second powder outlet hole 10. By rotating the second powder outlet chamber 8, it is possible to switch between the two states of the blocking flange 13 closing the first powder outlet hole 9 and the second powder outlet hole 10 being connected to the first powder outlet hole 9.
[0044] Continue to refer to Figure 2 and Figure 3 When the first powder outlet holes 9 on the first powder outlet chamber 7 are provided with a plurality of first powder outlet holes 9, a plurality of blocking flanges 13 are correspondingly provided on the side of the second powder outlet chamber 8 close to the first powder outlet chamber 7, so that the plurality of blocking flanges 13 and the plurality of second powder outlet holes 10 are arranged one by one, and the positions of the plurality of first powder outlet holes 9 and the plurality of second powder outlet holes 10 are correspondingly arranged. By rotating the second powder outlet chamber 8, it is possible to switch between two states: the plurality of first powder outlet holes 9 are closed synchronously by the plurality of blocking flanges 13, or the plurality of second powder outlet holes 10 are connected synchronously to the plurality of first powder outlet holes 9.
[0045] Continue to refer to Figure 2 and Figure 3 In another possible implementation, at least one accommodating groove 14 is circumferentially provided on one side of the first powder outlet chamber 7 close to the second powder outlet chamber 8, and the shape of the accommodating groove 14 is adapted to the sealing flange 13, and at least one accommodating groove 14 corresponds one-to-one to at least one sealing flange 13 for accommodating the sealing flange 13.
[0046] Continue to refer to Figure 2 and Figure 3 , when the first powder outlet hole 9 on the first powder outlet chamber 7 is set to one, a blocking flange 13 is correspondingly provided on the side of the second powder outlet chamber 8 close to the first powder outlet chamber 7, and a receiving groove 14 is correspondingly opened on the side of the first powder outlet chamber 7 close to the second powder outlet chamber 8, and the second powder outlet chamber 8 can be rotated to realize the switching between the two states of the blocking flange 13 closing the first powder outlet hole 9 and the blocking flange 13 being received in the receiving groove 14; Continue to refer to Figure 2 and Figure 3When the accommodating grooves 14 and the first powder outlet holes 9 are both provided in plurality, and the sealing flanges 13 and the second powder outlet holes 10 are provided in plurality accordingly, the plurality of accommodating grooves 14 and the plurality of first powder outlet holes 9 are arranged one by one at intervals, and the plurality of sealing flanges 13 and the plurality of second powder outlet holes 10 are arranged one by one at intervals. That is, when there are multiple first powder outlet holes 9 on the first powder outlet chamber 7, a plurality of blocking flanges 13 are correspondingly provided on the side of the second powder outlet chamber 8 close to the first powder outlet chamber 7, and the plurality of blocking flanges 13 and the plurality of second powder outlet holes 10 are arranged one by one, and a plurality of accommodating grooves 14 are correspondingly opened on the side of the first powder outlet chamber 7 close to the second powder outlet chamber 8, and the plurality of accommodating grooves 14 and the plurality of first powder outlet holes 9 are arranged one by one, by rotating the second powder outlet chamber 8, it is possible to switch between the two states of synchronously closing the plurality of first powder outlet holes 9 by the plurality of blocking flanges 13 and synchronously accommodating the plurality of blocking flanges 13 in the plurality of accommodating grooves 14; and one rotation can realize whether the plurality of first powder outlet holes 9 and the plurality of second powder outlet holes 10 are synchronously connected or not.
[0047] Continue to refer to Figure 2 and Figure 3 During the powder taking process, the first partition block 201 is rotated so that the blocking flange 13 no longer closes the first powder outlet hole 9, and the portion between the two adjacent second powder outlet holes 10 of the second powder outlet chamber 8 is pushed outwards under the action of the blocking flange 13. In this embodiment, the portion between the two adjacent second powder outlet holes 10 of the second powder outlet chamber 8 is referred to as the elastic portion 15, and the same applies hereinafter; the blocking flange 13 is further rotated so that it is located at the receiving groove 14, and the blocking flange 13 is located in the receiving groove 14 under the action of the restoring force of the elastic portion 15, which is the first position at this time. At this time, the elastic portion 15 returns to its original position and no longer has a restoring force, which reduces the retention time of the elastic portion 15 in the bent state during powder taking, and thus it is not easy to produce irreversible deformation.
[0048] Continue to refer to Figure 2 and Figure 3 , one end of the first powder outlet hole 9 close to the second powder outlet cavity 8 can be provided with a countersunk hole 16 to increase the contact area with the blocking flange 13. At the same time, the depth of the countersunk part of the first powder outlet hole 9 can be made shallower than the depth of the accommodating groove 14. When the blocking flange 13 is located in the accommodating groove 14, the elastic part 15 no longer has a restoring force. When the blocking flange 13 is rotated so that it is located in the shallower countersunk hole 16, the blocking flange 13 and the shallower countersunk hole 16 cause the elastic part 15 to be pushed outward with a small amplitude to obtain a small restoring force, thereby increasing the static friction between the surface of the blocking flange 13 and the wall of the countersunk hole 16, so that the blocking flange 13 is relatively stably pressed against the countersunk hole 16 to close the first powder outlet hole 9.
[0049] Continue to refer to Figure 2 and Figure 3In another embodiment, the first dividing block 201 also includes a guide column 17 located at the center position, and the first powder outlet chamber 7 is arranged around the guide column 17. The guide column 17 passes through the arc-shaped side wall at one end of the avoidance hole 11 and has an annular limiting flange 18 integrally formed thereon. The limiting flange 18 is used to limit the axial movement of the second powder outlet chamber 8 on the guide ring 5.
[0050] Continue to refer to Figure 2 and Figure 3 When only one second powder outlet hole 10 is provided, the limiting flange 18 on the periphery of the guide column 17 cooperates with the inner side of the second powder outlet chamber 8 close to the avoidance hole 11 to prevent the second partition block 202 from being separated from the first partition block 201 along the axial direction of the guide ring 5.
[0051] Continue to refer to Figure 2 and Figure 3 In another embodiment, there is a preset distance between the limiting flange 18 and the second powder outlet cavity 8 in the axial direction of the guide ring 5. For example, in some of the above embodiments with the blocking flange 13, the movement of the blocking flange 13 will push the second powder outlet cavity 8 outward, and a preset distance is set between the limiting flange 18 and the second powder outlet cavity 8 in the axial direction of the guide ring 5, which is specifically determined according to the height of the blocking flange 13; for another example, in the above example, the accommodating groove 14 and the first powder outlet hole 9 are both set to multiple, and the blocking flange 13 and the second powder outlet hole 10 are also correspondingly set to multiple, and the multiple accommodating grooves 14 and the multiple first powder outlet holes 9 are arranged one by one, and the multiple blocking flanges 13 and the multiple second powder outlet holes 10 are arranged one by one, and there is a preset distance between the limiting flange 18 and the elastic part 15 in the axial direction of the guide ring 5 to make way for the outward push of the elastic part 15. In addition, the height of the limiting flange 18 in the radial direction of the guide ring 5 can also be limited so that when the second partition block 202 moves outward along the axial direction of the guide ring 5, it only contacts the inner side of the second powder outlet chamber 8 or the inner side of the elastic part 15 to facilitate assembly.
[0052] Continue to refer to Figure 2 and Figure 3 As a possible implementation method, a positioning component can be further provided between the first dividing block 201 and the second dividing block 202 to limit the rotation angle of the first dividing block 201 and the second dividing block 202, so as to realize switching between the first position and the second position without excessive rotation. The positioning component can be a positioning column 19 installed on the second dividing block 202, and an arc-shaped positioning groove 20 is provided on the first dividing block 201 to slide with the positioning column 19. The positions of the positioning column 19 at both ends of the positioning groove 20 correspond to the first position and the second position respectively, so as to realize positioning.
[0053] Based on the above embodiment, the following settings can also be performed: Continue to refer to Figure 2 and Figure 3 , the side of the first powder outlet chamber 7 close to the second dividing block 202 and the side of the second powder outlet chamber 8 facing the first dividing block 201 are inclined, wherein the side of the first powder outlet chamber 7 close to the second dividing block 202 is a first inclined surface 21, and the first inclined surface 21 is inclined from away from the middle of the first dividing block 201 to close to the middle of the first dividing block 201, and from away from the second dividing block 202 to close to the second dividing block 202; the thickness of the second powder outlet chamber 8 gradually thickens from close to the middle of the second dividing block 202 to away from the middle of the second dividing block 202, and the side of the second powder outlet chamber 8 facing the first dividing block 201 is a second inclined surface 22 adapted to the first inclined surface 21, and the second inclined surface 22 is inclined from away from the middle of the second dividing block 202 to close to the middle of the second dividing block 202, and from close to the first dividing block 201 to away from the first dividing block 201.
[0054] Continue to refer to Figure 2 and Figure 3 By means of the inclined first powder outlet chamber 7 and the second powder outlet chamber 8, the loose powder remaining between the first powder outlet chamber 7 and the second powder outlet chamber 8 can gradually move toward the outer edge of the inner side of the guide ring 5 and gather, so as to facilitate the subsequent reflux treatment; and the thickness of the second powder outlet chamber 8 gradually thickens from the middle part close to the second dividing block 202 toward the middle part away from the second dividing block 202, achieving an effect similar to that of a reinforcing rib. When there are multiple second powder outlet holes 10, the elastic part 15 has a higher strength and is not prone to irreversible deformation.
[0055] Continue to refer to Figure 2 and Figure 3 In order to improve the reflux efficiency, a drainage channel 23 is opened along the axial direction of the guide ring 5 in the first powder outlet hole 9, close to the outer side of the guide ring 5, or close to the side of the guide groove 6. The drainage channel 23 extends the length of the side hole wall so that the loose powder gathered on the outer edge of the inner side of the guide ring 5 can flow back into the accommodating chamber 3 smoothly through the drainage channel 23.
[0056] Continue to refer to Figure 2 and Figure 3As mentioned above, the first partition block 201 and the second partition block 202 are plate-shaped as a whole. In some embodiments, the partition block appears as the bottom of a box-like structure. For example, a first extension wall 24 is formed on the first partition block 201 and extends circumferentially toward a side close to the second partition block 202. A second extension wall 25 is formed on the second partition block 202 and extends circumferentially toward a side away from the first partition block 201. The first partition block 201 and the first extension wall 24 form a box-like structure. The first extension wall 24 serves as a box wall of the box-like structure. The first partition block 201 serves as a box bottom of the box-like structure, and the second partition block 202 serves as the same. The first extension wall 24 is located outside the second extension wall 25. The first partition block 201 is first installed in the box body 1, and then the second partition block 202 is installed. Continue to refer to Figure 2 and Figure 3 To facilitate assembly, an elastic snap ring 26 is circumferentially provided on one side of the second extension wall 25 close to the first extension wall 24, and a gap 27 is provided between the elastic snap ring 26 and the second extension wall 25; a second flange 28 is circumferentially provided on the outer side of the elastic snap ring 26, and a first flange 29 is circumferentially provided on the inner side of the first extension wall 24. The first flange 29 and the first partition block 201 form a slot 30 for the second flange 28 to be snapped together. The surfaces of the first flange 29 and the second flange 28 are both curved surface transitions, and the cross-section is preferably a minor arc. When the second partition block 202 is assembled with the first partition block 201 along the axial direction of the guide ring 5, the second flange 28 of the elastic snap ring 26 contacts the first flange 29. Because there is a gap 27 between the elastic snap ring 26 and the second extension wall 25, the elastic snap ring 26 can enter the slot 30 through the restoring force after avoiding the position and snap-fitting, thereby realizing the assembly between the first partition block 201 and the second partition block 202, and can rotate relatively.
[0057] Continue to refer to Figure 2 and Figure 3 In this embodiment, since the first extension wall 24 and the second extension wall 25 are additionally provided, the above-mentioned positioning assembly can also be installed between the first extension wall 24 and the second extension wall 25, which will not be described in detail herein.
[0058] Continue to refer to Figure 2 and Figure 3 Furthermore, one end of the second extension wall 25 away from the second partition block 202 passes over the opening side wall of the box body 1 and is rotated and connected to the outer edge of the opening side wall of the box body 1, so that the user can hold and apply force to drive the second partition block 202 to rotate; Continue to refer to Figure 2 and Figure 3The materials of the first dividing block 201, the second dividing block 202, the first extending wall 24 and the second extending wall 25 can be materials with certain hardness and toughness, such as plastic, and the inner side of the part of the second extending wall 25 that is turned out of the box body 1 and the outer edge of the opening side of the box body 1 can also be nested and engaged with each other by means of two flanges, limiting axial movement but allowing relative rotation; the outer side of the part of the second extending wall 25 that is turned out of the box body 1 can be provided with anti-slip grooves 31 for manual driving.
[0059] Continue to refer to Figure 2 and Figure 3 The connection between the first partition block 201 and the box body 1 can be achieved by providing a ring-shaped slot 32 and an insert strip 33 between the periphery of the first partition block 201 and the inner side of the box body 1 to achieve plug-in fit, thereby achieving an assemblable connection between the two and limiting the rotation of the first partition block 201, thereby providing the possibility of multiple filling of loose powder.
[0060] Continue to refer to Figure 2 and Figure 3 It can be understood that the powder box can also include a cover body 34 for closing the opening of the box body 1, and the connection between the cover body 34 and the powder box can be achieved by various covering methods such as hinged connection, threaded connection, and snap fixation, which are not limited here.
[0061] Continue to refer to Figure 2 and Figure 3 As a possible implementation method, a feed port can be set at the bottom of the box body 1, and a closure member for closing the feed port can be set at the feed position, such as a threaded connection with a closing plate, a snap-fitting closing plate, etc., to achieve a detachable closure of the feed port for the addition of loose powder.
[0062] Reference Figure 4 The loose powder box can also include a prefabricated tearing claw hand 35 to remind consumers that the loose powder contained in this example has not been used by others. The prefabricated tearing claw hand 35 includes a handle 351 for applying force and a plurality of sub-claw hands 352 connected to one end of the handle 351. The sub-claw hands 352 are connected to the second powder outlet 10 through a connection point. The prefabricated tearing claw hand can be integrally injection molded by a mold when the second partition block 202 is formed. When used for the first time, the prefabricated tearing claw hand 35 of this example is pulled out and discarded at one time to take out the loose powder.
[0063] The above specific implementations do not constitute a limitation on the protection scope of this application. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this application should be included in the protection scope of this application.
