Abstract
Description
Technical Field
[0001] This utility model relates to the field of makeup brush technology, specifically to a multi-head replaceable makeup brush. Background Technology
[0002] To allow a single brush handle to accommodate multiple different brush heads, most makeup brushes on the market today feature a detachable design between the handle and the brush head. When users need to change brush heads to suit different makeup steps, they typically simply pull out the old brush head and insert the new one into the handle.
[0003] During the process of inserting and removing the brush head, the bristles on the brush head are directly exposed to the outside. If the user is not careful, they will directly touch the bristles on the brush head. This not only makes it very easy for the bristles to become misaligned, bent or even fall off during the insertion and removal process, but also makes it easy for the bristles to come into contact with external dirt and cause contamination.
[0004] Therefore, how to effectively prevent damage and contamination of makeup brush bristles during brush head replacement is a key challenge that technical personnel in the field of beauty tool research and development urgently need to overcome. Utility Model Content
[0005] In order to effectively avoid damage and contamination of makeup brush bristles, this application provides a multi-head replaceable makeup brush.
[0006] The multi-head replaceable makeup brush provided in this application adopts the following technical solution:
[0007] A multi-head replaceable makeup brush includes a brush handle and multiple first protective sleeves. One end of the brush handle has a first insertion hole. Both ends of the first protective sleeve are configured as first insertion parts that match the first insertion hole. A sliding seat is slidably connected inside the first protective sleeve. A first brush head is installed on the sliding seat. A top rod is fixedly installed on the brush handle inside the first insertion hole corresponding to the sliding seat.
[0008] Furthermore, a first through hole is provided at one end of the first protective sleeve, and a second through hole is provided at the end of the first protective sleeve away from the first through hole. When the push rod passes through the first through hole and abuts against the sliding seat, the first brush head extends out from the second through hole. When the push rod passes through the second through hole and abuts against the sliding seat, the first brush head retracts from the second through hole.
[0009] Furthermore, an elastic element is provided between the sliding seat and the first protective sleeve to allow the first brush head to retract inside the first protective sleeve in its natural state.
[0010] Furthermore, the elastic element is configured as a spring, and a limiting ring is provided at the end of the first protective sleeve away from the first through hole, and the two ends of the spring respectively abut against the limiting ring and the sliding seat.
[0011] Furthermore, a fixing plate is fixedly connected inside the brush handle, and the top rod is fixedly installed on the fixing plate.
[0012] Furthermore, a second insertion hole is provided at the end of the brush handle away from the first insertion hole. A mounting base is installed inside the second insertion hole of the brush handle. Both ends of the mounting base are configured as second insertion parts that match the second insertion hole. The brush handle is inserted into the second insertion part through the second insertion hole. A second brush head and a third brush head are fixedly connected to both ends of the mounting base, respectively.
[0013] Furthermore, a second protective sleeve is fitted onto the end of the mounting base away from the brush handle. One end of the second protective sleeve has a third insertion hole corresponding to the second insertion part on the mounting base. The second protective sleeve is inserted into the second insertion part through the third insertion hole.
[0014] Furthermore, a bottom cover is fixedly connected to the end of the second protective sleeve away from the third insertion hole.
[0015] Furthermore, the outer side of the bottom cover is configured as a third insertion portion that matches the second insertion hole.
[0016] Furthermore, the first insertion part, the second insertion part, and the third insertion part are all cylindrical, and the first insertion hole, the second insertion hole, and the third insertion hole are all cylindrical holes that mate with the cylindrical shape.
[0017] In summary, this application includes at least one of the following beneficial technical effects:
[0018] This application slides the first brush head together with the sliding base inside the first protective sleeve. By using the pushing action of the push rod during the insertion and removal process, the first brush head can be retracted inside the first protective sleeve or pushed out from inside the first protective sleeve by changing the insertion direction of the first protective sleeve. During the brush head replacement process, damage and contamination of the makeup brush bristles are effectively avoided. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0028] This application discloses a multi-head replaceable makeup brush.
[0029] Please refer to Figures 1 to 3In one embodiment of this application, a multi-head replaceable makeup brush includes a brush handle 100 and multiple first protective sleeves 102. One end of the brush handle 100 is provided with a first insertion hole 101. Both ends of the first protective sleeves 102 are provided with first insertion portions 103 that match the first insertion hole 101. A sliding seat 104 is slidably connected inside the first protective sleeve 102. A first brush head 105 is installed on the sliding seat 104. A top rod 106 is fixedly installed on the brush handle 100 inside the first insertion hole 101 corresponding to the sliding seat 104.
[0030] The implementation principle of a multi-head replaceable makeup brush in this application embodiment is as follows:
[0031] When the makeup brush is not in use, the end of the protective cover 102 near the first brush head 105 can be inserted into the first socket 101 for storage. During the insertion process, the push rod 106 will insert the brush bristles and push the sliding seat 104. The first brush head 105 and the sliding seat 104 will retract into the first protective cover 102, thereby protecting the first brush head 105.
[0032] When the first brush head 105 is needed for makeup application, the corresponding first protective cover 102 is pulled out of the first socket 101, and the other end of the first protective cover 102 is inserted back into the first socket 101. During the insertion process, the push rod 106 will directly push the sliding seat 104 to push the first brush head 105 out of the first protective cover 102 for use.
[0033] Please refer to Figures 1 to 3 In one embodiment of this application, a first through hole 107 is provided at one end of the first protective sleeve 102, and a second through hole 108 is provided at the other end of the first protective sleeve 102 away from the first through hole 107. A hairless area is provided at the center of the first brush head 105 corresponding to the top rod 106. When the top rod 106 passes through the first through hole 107 and abuts against the sliding seat 104, the first brush head 105 extends out of the second through hole 108. When the top rod 106 passes through the second through hole 108 and abuts against the sliding seat 104, the first brush head 105 retracts from the second through hole 108.
[0034] When stored, the top rod 106 passes through the second through hole 108 and the bristle-free area and abuts against the sliding seat 104, causing the first brush head 105 mounted on the sliding seat 104 to retract inside the first protective sleeve 102. When in use, the top rod 106 passes through the first through hole 107 to push the sliding seat 104, extending the first brush head 105 out from inside the first protective sleeve 102. The bristle-free area design not only avoids contact and collision between the top rod 106 and the brush bristles when stored, but also allows for the storage of cosmetics when in use.
[0035] Please refer to Figures 1 to 3In one embodiment of this application, an elastic element 109 is provided between the sliding seat 104 and the first protective sleeve 102 so that the first brush head 105 retracts into the first protective sleeve 102 in its natural state.
[0036] During use, when the first protective sleeve 102 is inserted into the first insertion hole 101, the elastic element 109 stores elastic potential energy due to the pushing force between the first protective sleeve 102 and the sliding seat 104. When the first protective sleeve 102 is pulled out of the first insertion hole 101, the elastic element 109 releases the previously stored elastic potential energy, thereby applying a force towards the inside of the first protective sleeve 102 to the sliding seat 104, causing the sliding seat 104 to slide in the opposite direction along the inside of the first protective sleeve 102. Finally, the first brush head 105 retracts from the second through hole 108 into the first protective sleeve 102, returning to its natural retracted state. This ensures that the first brush head 105 is always retracted into the first protective sleeve 102 during insertion and removal, thus protecting the bristles on the first brush head 105 with the first protective sleeve 102.
[0037] Please refer to Figures 1 to 3 In one embodiment of this application, the elastic element 109 is configured as a spring, and a limiting ring 110 is provided at one end of the first protective sleeve 102 away from the first through hole 107. The two ends of the spring abut against the limiting ring 110 and the sliding seat 104, respectively.
[0038] During use, one end of the spring is tightly abutted against the limiting ring 110, while the other end of the spring abuts against the sliding seat 104. The cooperation between the limiting ring 110 and the spring ensures the stability of the spring during operation, making the direction and magnitude of the applied elastic force relatively stable. The presence of the limiting ring 110 also ensures that the sliding seat 104 will not fall out of the first protective sleeve 102.
[0039] Please refer to Figures 1 to 3 In one embodiment of this application, a fixing plate 111 is fixedly connected inside the brush handle 100, and the top rod 106 is fixedly installed on the fixing plate 111.
[0040] During use, the brush handle 100, the push rod 106, and the fixing plate 111 are fixedly connected, which makes the position of the push rod 106 within the brush handle 100 stable and fixed. When the user holds the brush handle 100, it avoids the first brush head 105 from moving due to external force, and the fixing plate 111 divides the inside of the brush handle 100 into different areas, which is conducive to the rational planning and layout of the internal space.
[0041] Please refer to Figures 1 to 3In one embodiment of this application, a second insertion hole 112 is provided at the end of the brush handle 100 away from the first insertion hole 101. A mounting base 113 is installed inside the second insertion hole 112 of the brush handle 100. Both ends of the mounting base 113 are provided as second insertion portions 114 that match the second insertion hole 112. The brush handle 100 is inserted into the second insertion portion 114 through the second insertion hole 112. A second brush head 115 and a third brush head 116 are fixedly connected to both ends of the mounting base 113, respectively.
[0042] This design, by providing a second brush head 115 and a third brush head 116, further increases the number of brush heads in the makeup brush, thus meeting the user's need to use multiple brush heads. During use, when the second brush head 115 or the third brush head 116 is needed, the user simply pulls the mounting base 113 out of the second insertion hole 112 on the brush handle 100, and then selects either the second brush head 115 or the third brush head 116 according to their makeup needs. When the second brush head 115 is needed, the second insertion part 114 on the mounting base 113, near the end of the third brush head 116, is inserted into the second insertion hole 112 on the brush handle 100. When the third brush head 116 is needed, the second insertion part 114 on the mounting base 113, near the end of the second brush head 115, is inserted into the second insertion hole 112 on the brush handle 100.
[0043] Please refer to Figures 1 to 3 In one embodiment of this application, a second protective sleeve 117 is fitted on the end of the mounting base 113 away from the brush handle 100. A third insertion hole 118 is provided at one end of the second protective sleeve 117 corresponding to the second insertion part 114 on the mounting base 113. The second protective sleeve 117 is inserted into the second insertion part 114 through the third insertion hole 118.
[0044] When storing, first insert the mounting base 113 onto the brush handle 100, then slip the second protective cover 117 onto the second insertion part 114 on the mounting base 113 at the end furthest from the brush handle 100. This will completely enclose the second brush head 115 and the third brush head 116. This prevents the second brush head 115 and the third brush head 116 from being bumped or scratched by the outside world during idle periods, avoiding damage such as bent or broken bristles.
[0045] Please refer to Figures 1 to 3 In one embodiment of this application, a bottom cover 119 is fixedly and sealed to the end of the second protective sleeve 117 away from the third insertion hole 118.
[0046] During use, the bottom cover 119 and the second protective cover 117 together form a closed space, completely covering the second brush head 115 and the third brush head 116, effectively preventing foreign objects from entering the second protective cover 117 from the bottom and coming into contact with the second brush head 115 and the third brush head 116, further enhancing the protection of the second brush head 115 and the third brush head 116.
[0047] Please refer to Figures 1 to 3 In one embodiment of this application, the outer side of the bottom cover 119 is configured as a third insertion portion 120 that matches the second insertion hole 112.
[0048] During use, first insert the bottom cover 119 into the second insertion hole 112 on the brush handle 100 through the third insertion part 120, and then insert the second insertion part 114 on the mounting base 113 into the third insertion hole 118 on the second protective cover 117. Then one of the second brush head 115 and the third brush head 116 can be used. This will extend the handle's grip range and make it more convenient to use.
[0049] Please refer to Figures 1 to 3 In one embodiment of this application, the first insertion part 103, the second insertion part 114 and the third insertion part 120 are all cylindrical, and the first insertion hole 101, the second insertion hole 112 and the third insertion hole 118 are all cylindrical holes that mate with the cylindrical shape.
[0050] Because the cylindrical shape precisely matches the shape of the cylindrical hole, the insertion part can be inserted into the corresponding hole more easily, and the cylindrical design is easier to shape and manufacture during the processing, which helps to reduce production costs.
[0051] Of course, in one embodiment of this application, the first insertion part 103, the second insertion part 114 and the third insertion part 120 may all be configured as polygonal, and the first insertion hole 101, the second insertion hole 112 and the third insertion hole 118 may all be configured as polygonal holes that cooperate with the polygonal shape.
[0052] Polygonal inserts, such as triangular or quadrilateral inserts, can achieve absolute anti-rotation when used with polygonal sockets. Taking a quadrilateral as an example, when the first insert of the quadrilateral is inserted into the first socket of the quadrilateral, the four sides correspond to each other, and no relative rotation can occur at any angle unless force is applied along a specific insertion / removal direction.
[0053] Please refer to Figures 1 to 4In one embodiment of this application, the mounting base 113 is provided with a plurality of first fixing holes 121 at the connection points of the second socket 112 and the third socket 118 respectively. The second socket 112 and the third socket 118 are respectively fixedly installed with fixing bases 122 corresponding to the first fixing holes 121. The fixing bases 122 are detachably connected to the mounting base 113 through the first fixing holes 121.
[0054] During use, the fixing seat 122 on the brush handle 100 is aligned with the corresponding first fixing hole 121 on the mounting base 113, so that the fixing seat 122 is inserted into the first fixing hole 121, thereby achieving a stable connection between the brush handle 100 and the mounting base 113. Similarly, when connecting the second protective sleeve 117 to the mounting base 113, the fixing seat 122 on the second protective sleeve 117 is aligned with the corresponding first fixing hole 121 on the mounting base 113, thereby achieving a stable connection between the second protective sleeve 117 and the mounting base 113. During disassembly, the fixing seat 122 is detached from the first fixing hole 121, and the components can be separated.
[0055] This connection method ensures that the connection between the brush handle 100 or the second protective cover 117 and the mounting base 113 is secure and not easily loosened during storage or use.
[0056] Please refer to Figures 1 to 5 In one embodiment of this application, the end of the bottom cover 119 away from the second protective sleeve 117 is provided with a second fixing hole 123 corresponding to the fixing seat 122, and the fixing seat 122 is inserted into the bottom cover 119 through the second fixing hole 123.
[0057] When using the second brush head 115 or the third brush head 116, the fixing seat 122 on the brush handle 100 is aligned with the second fixing hole 123 on the bottom cover 119, and then the fixing seat 122 is inserted into the second fixing hole 123. The two fit together tightly to achieve a stable connection between the bottom cover 119 and the brush handle 100.
[0058] This structure works in conjunction with the connection method of the first fixing hole 121 and the fixing seat 122 on the mounting base 113 to jointly construct a flexible and stable connection system between the various parts of the makeup brush.
[0059] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
