[0002] As people pay more and more attention to dental health, interdental brushes for cleaning between teeth are becoming more and more popular. An interdental brush generally includes a brush handle and a brush head at the end of the brush handle. When in use, hold the brush handle and use the bristles on the brush head to clean the gaps between teeth. In order to extend the service life of the interdental brush, the brush head and the brush handle are generally fixed in a detachable connection. When sold, multiple brush heads are often configured for a single brush handle to reduce the user's cost.

[0003] Interdental brushes need to be packaged in a box when they are sold.

DETAILED DESCRIPTION

[0028] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0029] Example

[0030] See also Figures 1 to 7 A packaging box for an interdental brush comprises an outer box body 1 and a box cover 2 which is covered on top of the outer box body and hinged to one side of the outer box body, wherein an inner box body 3 and a brush head placement box 4 are detachably installed in the outer box body 1, and a placement groove 31 for placing the handle of the interdental brush is provided on the inner box body, and the brush head placement box 4 comprises a matching seat 42, and a plurality of brush head placement cavities 422 for placing the brush heads are provided in the matching seat, and the depth of the brush head placement cavity is less than the length of the brush head so that the brush head is partially exposed outside the brush head placement cavity, and a detachable upper cover 41 is also provided above the matching seat, and a cam assembly 43 is installed in the matching seat 42, and the upper cover is lifted and lowered along the height direction of the matching seat by the cam assembly, and through holes corresponding to the brush head placement cavities are provided on the upper cover so that the brush heads extend out of the top surface of the upper cover when the upper cover is lowered.

[0031] A base 44 is installed below the matching seat 42. The bottom of the cam assembly is connected to the base through a spring. The top of the cam assembly passes through the top of the matching seat and abuts against the upper cover. A guide pipe 421 is provided in the matching seat. The cam assembly includes an upper cam 431 abutting against the upper cover and a lower cam connected to the base. A limit ring is provided at the upper end of the guide pipe. An upper limit strip 4312 having a size larger than the inner diameter of the limit ring is provided on the outer ring of the upper cam. When the upper cam rises, the upper limit strip is limited by the limit ring to prevent the upper cam from completely extending out of the matching seat. When the brush head needs to be taken, the upper cover is controlled to rise and fall by the cam assembly. When the upper cover descends, the brush head extends from the through hole of the upper cover, and the brush head can be taken through the part of the brush head exposed outside the upper cover.

[0032] The inner wall of the guide pipe 421 is ring-shaped with multiple groups of limit teeth 4211 extending toward the center of the wire pipe, and there is a gap between each group of limit teeth. A lower limit bar 4322 is provided on the outer side of the lower cam 432, and the width of the lower limit bar and the upper limit bar does not exceed the width of the gap between each group of limit teeth.

[0033] The bottom of the limiting tooth 4211 is inclined and has a smooth arc to facilitate the movement of the lower limiting bar along the bottom surface of the limiting tooth. The middle section of the limiting tooth is provided with a limiting groove that is adapted to the upper limiting bar 4312 and penetrates the limiting tooth.

[0034] The upper cam 431 and the lower cam 432 are both cylindrical, with a matching hole 4311 provided at the center of the upper cam and a matching column 4322 matched with the matching hole provided at the center of the lower cam. The matching column is inserted into the matching hole to radially limit the upper cam and the lower cam, and the contact ends of the upper cam and the lower cam are both provided with teeth matched with each other.

[0035] When the upper limit bar 4312 and the lower limit bar 4322 are both located in the gap between the limit teeth or in the limit grooves on the limit teeth, the teeth of the upper limit bar and the lower limit bar are in a non-engaged or non-fully engaged state.

[0036] Positioning holes 423 are formed near both ends of the matching seat 42 , and positioning posts are provided on the bottom side of the upper cover 41 . The positions and sizes of the positioning posts and the positioning holes are adapted to each other.

[0037] The outer box body 1 is provided with a limiting groove 12, the base 44 is fixed in the limiting groove, and the matching seat 42 is detachably fixedly connected to the base.

[0038] The inner box body 3 is provided with an avoidance hole 32 adapted to the outer edge of the matching seat, and the matching seat passes through the avoidance hole and is exposed on the top surface of the inner box body.

[0039] A guide hole 311 is provided in the placement groove 31 of the inner box body 3, and a hollow guide column 11 connected to the guide hole is provided inside the outer box body 1, and the guide hole is connected to the outside of the outer box body through the guide column. Since the interdental brush is often washed with water after use, the residual water of the interdental brush can be promptly led out of the packaging box through the guide hole.

[0040] In the interdental brush packaging box of this embodiment, when packaging, the replacement brush heads are placed in the brush head placement cavity 422, and the upper cover 41 is closed on the top of the matching seat 42. When the brush head needs to be taken out, the upper cover needs to be lowered first to allow the brush head to extend out from the through hole of the upper cover. The movement of the upper cover in cooperation with the cam assembly 43 is as follows: the upper cover is pressed so that the upper cam 431 is subjected to downward pressure, and the upper cam pushes the lower cam 432 to move downward. When the lower limit strip 4322 on the lower cam is separated from the limit tooth 4211 in the guide pipe 421, the lower cam is no longer limited by the limit groove, and rotates under the cooperation of the lower cam and the upper cam teeth. The rotation also causes the gap between the lower limit strip and the limit tooth to be misaligned. At this time, after the pressure on the upper cover is removed, the lower cam is limited by the limit tooth ground No rebound will occur, that is, the upper cover is lowered; and after use, in order to improve the protection effect of the remaining brush heads, the upper cover needs to rise again. At this time, you only need to continue pressing the upper cover, and the lower cam moves downward. Due to the action of the toothed arc surface of the bottom surface of the limiting tooth, the lower cam continues to rotate along the limiting tooth under the cooperation of the lower limit bar and the bottom surface of the limiting tooth, until the lower limit bar enters the gap adjacent to the gap in the aforementioned process. At this time, the lower cam loses the limit of the limiting tooth and can complete the rise under the action of the spring, which also drives the rise of the upper cover.

[0041] The beneficial effect of the utility model is that a brush head placement box guided by a cam assembly is provided in the packaging box, and the lifting and lowering of the upper cover is controlled by cooperating with the matching seat in the brush head placement box, thereby controlling the brush head to extend or retract into the brush head placement box. When the user takes the brush head and other parts, he only needs to press the upper cover, which is more convenient to use. When not in use, the brush head can be protected from contamination and damage, and the user experience is better.

[0042] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are illustrative and cannot be construed as limitations of the present invention. A person skilled in the art may change, modify and vary the above embodiments within the scope of the present invention.
