Description

Technical Field

[0001] This technical solution relates to the field of daily necessities technology, specifically a baby bottle brush. Background Technology

[0002] A bottle brush is a tool used to clean baby bottles, effectively cleaning the inside of the bottle and ensuring its hygiene. A typical bottle brush usually consists of a handle and a brush head. To use it, hold the handle and insert the brush head into the bottle to scrub the inside and bottom.

[0003] However, due to the pointed shape of baby bottle nipples, traditional bottle brushes cannot reach deep into the inner wall of the nipple for cleaning, making bottle brushes relatively limited in function. A separate nipple brush is often needed for cleaning, but these two brushes are designed separately, taking up space when stored and being easy to lose due to their large quantity. Utility Model Content

[0004] The purpose of this technical solution is to provide a baby bottle brush. By installing a baby bottle brush and a nipple brush at both ends of the snap-fit ​​connector, the snap-fit ​​connector and the snap-fit ​​interface are snapped together after the baby bottle brush or nipple brush is inserted into the box, thus realizing the installation of the brush device on the box. This improves the problem of large storage space and easy loss caused by the traditional separate design of baby bottle brush and nipple brush.

[0009] The box has a snap-fit ​​interface. When the bottle brush or the nipple brush is inserted into the box, the snap-fit ​​component snaps into the snap-fit ​​interface, thereby mounting the brush device onto the box.

[0010] Preferably, the bottle brush includes: a bottle brush head and a telescopic mechanism, with the two ends of the telescopic mechanism respectively connected to the snap-fit ​​component and the bottle brush head, and the telescopic mechanism is used to adjust the distance between the bottle brush head and the snap-fit ​​component;

[0011] The telescopic mechanism includes a fixed rod, a movable rod, and a limiting component. The rear end of the fixed rod is connected to the snap-fit ​​component. The fixed rod has a movable cavity inside, and the opening of the movable cavity passes through the front end of the fixed rod. The movable rod is slidably placed in the movable cavity. The front end of the movable rod is connected to the bottle brush head. The limiting component is installed between the movable rod and the fixed rod to restrict the movement of the movable rod within the fixed rod.

[0012] Preferably, the limiting component includes: a limiting member and an elastic member; the side wall of the movable rod is provided with a mounting groove, the limiting member is slidably disposed in the mounting groove, the limiting member is provided with a limiting part, and the side wall of the fixed rod is provided with a plurality of limiting holes distributed along its length direction; the limiting part engages with the corresponding limiting hole to limit the movement of the movable rod within the fixed rod;

[0013] The elastic element connects the limiting element and the mounting groove, and the elastic element is used to place the limiting part inside the limiting hole.

[0014] Preferably, the limiting member has an anti-detachment part, which movably abuts against the edge of the limiting hole to prevent the limiting member from detaching from the movable cavity.

[0015] Preferably, the inner wall of the fixed rod is provided with at least one rotation limiting part, and the outer wall of the movable rod is provided with at least one rotation limiting groove. The rotation limiting part is slidably placed in the corresponding rotation limiting groove to limit the rotation of the movable rod in the movable cavity.

[0016] Preferably, the side wall of the limiting member is provided with at least one guide groove, and the side wall of the mounting groove is provided with at least one guide part. The guide part is movably placed in the corresponding guide groove, so that the limiting member is slidably installed in the mounting groove.

[0017] Preferably, the nipple brush includes a nipple brush head and a brush handle, the rear end of the brush handle is connected to the snap-fit ​​member, and the front end of the brush handle is connected to the nipple brush head.

[0018] Preferably, the side wall of the snap-fit ​​component is provided with a snap-fit ​​part, and the snap-fit ​​interface is provided with a snap-fit ​​groove.

[0019] The snap-fit ​​part is placed in the snap-fit ​​groove to achieve snap-fit ​​between the snap-fit ​​part and the box body.

[0020] Preferably, it further includes:

[0021] A lid, which is connected to the box body or the snap-fit ​​component;

[0022] After the bottle brush is placed inside the box, the box lid covers the nipple brush.

[0023] Preferably, the box cover is provided with a second snap-fit ​​groove, and the snap-fit ​​part of the snap-fit ​​component includes a first snap-fit ​​part and a second snap-fit ​​part;

[0025] When the nipple brush is inserted into the box, the second snap-fit ​​part snaps into the first snap-fit ​​slot of the first snap-fit ​​interface.

[0026] The key and beneficial technical effects of this technical solution compared to existing technologies are:

[0027] 1. This technical solution installs the bottle brush and nipple brush separately on both ends of the snap-fit ​​connector. This combination reduces the need for separate storage of the two, avoids the hassle of separate storage required by a split design, and also reduces the possibility of loss due to scattered placement of the bottle brush and nipple brush. At the same time, the snap-fit ​​connector can be snapped into the box body. If the bottle brush is placed inside the box, the nipple brush will be outside the box for cleaning the nipple. If the nipple brush is placed inside the box, the bottle brush will be outside the box for cleaning the bottle. Furthermore, the box body can also serve as a handle, making it convenient for users to hold and operate, making the application of force during cleaning more stable, reducing hand fatigue, and improving the comfort of use.

[0028] 2. The bottle brush of this technical solution includes a bottle brush head and a telescopic mechanism. The distance between the bottle brush head and the snap-fit ​​part can be adjusted by the telescopic mechanism, so as to cope with the cleaning of bottles of different depths. It can be adapted to bottles of different sizes and depths without the need to change different sizes of brush heads or tools, which enhances versatility and applicability and reduces the cost for users to equip themselves with additional cleaning tools for cleaning bottles of different sizes.

[0040] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings. See also Figures 1-6 .

[0041] See Figure 1 and Figure 6 A baby bottle brush includes: a box body 1, a brush device 2, and a box cover 5; the brush device 2 is detachably connected to the box body 1, that is, the brush device 2 can be detached from the box body 1; wherein, the brush device 2 includes: a snap-fit ​​member 21, a baby bottle brush 3, and a nipple brush 4; the baby bottle brush 3 is installed at one end of the snap-fit ​​member 21, and the nipple brush 4 is installed at the other end of the snap-fit ​​member 21; the box cover 5 is threadedly connected or snap-fitted to the box body 1 or the snap-fit ​​member 21.

[0042] The box body 1 has a snap-fit ​​interface 11. When the bottle brush 3 or the nipple brush 4 is inserted into the box body 1, the snap-fit ​​piece 21 snaps into the snap-fit ​​interface 11, so that the brush device 2 is installed on the box body 1. That is, when the bottle brush 3 is inserted into the box body 1, the snap-fit ​​piece 21 snaps into the snap-fit ​​interface 11, and the nipple brush 4 will be located on the outside of the box body 1. At this time, the nipple brush 4 can be used to clean the nipple. When the nipple brush 4 is inserted into the box body 1, the snap-fit ​​piece 21 will also snap into the snap-fit ​​interface 11, and the bottle brush 3 will be located on the outside of the box body 1. At this time, the bottle brush 3 can be used to clean the bottle, and the box body 1 can be used as a handle for the user to hold and apply force when cleaning.

[0043] Combination Figures 1-4The bottle brush 3 includes a bottle brush head 30 and a telescopic mechanism 31. The bottle brush head 30 is made of materials such as sponge, nylon bristles, or silicone. The shape of the bottle brush head 30 can be cylindrical, elliptical, or spherical, etc., which are adapted to the shape of the bottle body. The telescopic mechanism 31 is connected to the snap-fit ​​piece 21 and the bottle brush head 30 at both ends. The telescopic mechanism 31 is used to adjust the distance between the bottle brush head 30 and the snap-fit ​​piece 21, so that the bottle brush 3 can meet the cleaning needs of bottles of different depths.

[0044] The telescopic mechanism 31 includes a fixed rod 32, a movable rod 33, and a limiting component 34. The rear end of the fixed rod 32 is connected to the snap-fit ​​component 21. The fixed rod 32 has a movable cavity 321 inside, and the opening of the movable cavity 321 passes through the front end of the fixed rod 32. The movable rod 33 is slidably placed in the movable cavity 321. The front end of the movable rod 33 is connected to the bottle brush head 30. The movable rod 33 can slide in the movable cavity 321 to adjust the distance between the bottle brush head 30 and the snap-fit ​​component 21. The limiting component 34 is installed between the movable rod 33 and the fixed rod 32. The limiting component 34 is used to restrict the movement of the movable rod 33 in the fixed rod 32, and the position of the movable rod 33 on the fixed rod 32 is fixed by the limiting component 34.

[0045] Combination Figures 1-3 The bottle brush head 30 is provided with a connecting rod 301. The rear end of the connecting rod 301 is inserted into the front end of the movable rod 33 through an interference fit. The front side wall of the connecting rod 301 is provided with several barbs 302, which are used to connect with the bottle brush head 30 to prevent the bottle brush head 30 from detaching from the connecting rod 301. The front end of the connecting rod 301 or the movable rod 33 has a limiting boss 303, which can abut against the front end of the fixed rod 32. The limiting boss 303 restricts the range of movement of the movable rod 33 within the fixed rod 32.

[0046] Combination Figures 3-5 The limiting component 34 includes a limiting member 35 and an elastic member 36. The side wall of the movable rod 33 is provided with a mounting groove 331, in which the limiting member 35 is slidably disposed. The limiting member 35 is provided with a limiting part 351, which is a button part. The side wall of the fixed rod 32 has several limiting holes 322 distributed along its length. In this design, a limiting hole 322 is provided on the side wall of the front half and the side wall of the rear half of the fixed rod 32, respectively, to realize the two length adjustment positions of the telescopic mechanism 31. The limiting part 351 engages with the corresponding limiting hole 322 to limit the movement of the movable rod 33 within the fixed rod 32. By adjusting the engagement of the limiting part 351 with the limiting hole 322 at different positions, the overall length of the fixed rod 32 and the movable rod 33 can be adjusted, thereby adjusting the distance between the bottle brush head 30 and the engaging member 21.

[0047] The elastic element 36 is a spring, disc spring, or rubber elastic block. The elastic element 36 connects the limiting element 35 and the mounting groove 331. The elastic deformation of the elastic element 36 causes the limiting element 35 to have a tendency to disengage from the groove of the mounting groove 331. That is, the elastic deformation of the elastic element 36 allows the limiting part 351 to be placed in the limiting hole 322. The bottom of the mounting groove 331 has a positioning post, the lower end of the limiting element 35 has a positioning groove, the lower end of the elastic element 36 is sleeved on the positioning post, and the upper end of the elastic element 36 is inserted into the positioning groove.

[0048] By pressing the limiting part 351 and disengaging it from the limiting hole 322, the movable rod 33 slides out or retracts on the fixed rod 32, thereby adjusting the overall length of the telescopic mechanism 31, that is, adjusting the distance between the bottle brush head 30 and the snap-fit ​​part 21.

[0049] Combination Figure 4 and Figure 5 The limiting member 35 has an anti-detachment part 352, and a limiting part 351 is formed at the upper middle part of the anti-detachment part 352. The diameter of the anti-detachment part 352 is larger than the diameter of the limiting hole 322. The anti-detachment part 352 moves to abut against the edge of the limiting hole 322, restricting the limiting member 35 from detaching from the movable cavity 321. The limiting member 35 is restricted in the mounting groove 331 by the edge of the limiting hole 322, so as to prevent the limiting member 35 from falling out of the movable cavity 321 under the action of the elastic member 36.

[0050] Combination Figure 3 and Figure 4 The inner sidewall of the fixed rod 32 is provided with at least one rotation limiting part 323, which is a rotation limiting protrusion distributed along the length direction of the fixed rod 32. The outer sidewall of the movable rod 33 is provided with a corresponding rotation limiting groove 332 along the length direction of the movable rod 33. The rotation limiting part 323 is slidably placed in the corresponding rotation limiting groove 332 to limit the rotation of the movable rod 33 in the movable cavity 321, so as to ensure that after the movable rod 33 moves in the movable cavity 321, the limiting part 351 can be placed in the limiting hole 322 under the action of the elastic member 36.

[0051] like Figure 4 The side wall of the limiting member 35 is provided with at least one guide groove 353, and the side wall of the mounting groove 331 is provided with at least one guide part 333. The guide parts 333 are distributed along the direction from the bottom of the mounting groove 331 to the opening of the groove. In this technical solution, a guide groove 353 is provided on each of the opposite sides of the anti-detachment part 352, and a guide part 333 is provided on each of the opposite side walls of the mounting groove 331. The guide parts 333 are movably placed in the corresponding guide groove 353, so as to realize that the limiting member 35 is slidably installed in the mounting groove 331, and ensure that the limiting member 35 slides in the mounting groove 331.

[0052] Combination Figures 1 to 3The nipple brush 4 includes a nipple brush head 40 and a brush handle 41. The nipple brush head 40 has a number of nylon bristles or silicone bristles on its surface, and the nipple brush head 40 is tapered and can be adapted to the internal shape of the nipple. The rear end of the brush handle 41 is connected to the snap-fit ​​member 21, and the front end of the brush handle 41 is connected to the nipple brush head 40 by adhesive bonding, interference fit, insertion, or injection molding.

[0053] The rear end of the fixing rod 32 of the bottle brush 3 and the rear end of the brush handle 41 of the nipple brush 4 are connected and fixed by plug-in or threaded connection. The middle part of the snap-fit ​​part 21 has a connecting through hole. The connecting parts of the fixing rod 32 and the brush handle 41 are placed in the connecting through hole and are installed and fixed by interference fit, threaded connection or adhesive connection.

[0054] like Figure 1 The side wall of the snap-fit ​​component 21 is provided with a snap-fit ​​part 22, and the inner side wall of the snap-fit ​​interface 11 is provided with a snap-fit ​​groove 12, which is an annular groove; by external force, the snap-fit ​​component 21 is inserted into the snap-fit ​​interface 11, and the snap-fit ​​part 22 is placed in the snap-fit ​​groove 12, so as to realize the snap-fit ​​between the snap-fit ​​component 21 and the box body 1.

[0055] The snap-fit ​​portion 22 is a protrusion or at least one protrusion, and one or more rows of snap-fit ​​portions 22 are arranged along the axis or length direction of the snap-fit ​​member 21 on the side wall of the snap-fit ​​member 21. In this invention, the snap-fit ​​portion 22 is a plurality of protrusions, and the plurality of protrusions are arranged around the periphery of the snap-fit ​​member 21 (forming one row / circle) and two rows are arranged. When the bottle brush 3 or nipple brush 4 is switched and inserted into the box body 1, the snap-fit ​​portions 22 of the same row or different rows can be inserted into the snap-fit ​​slot 12 to realize the snap-fit ​​between the snap-fit ​​member 21 and the snap-fit ​​interface 11.

[0056] After the bottle brush 3 is placed inside the box 1, the lid 5 covers the nipple brush 4, thus storing the nipple brush 4 and preventing it from being exposed and causing hygiene problems.

[0057] like Figure 1 and Figure 2 The cover 5 has a second card interface 51 for inserting the card connector 21. A second card slot 52 is provided in the second card interface 51. The second card slot 52 is an annular groove. The second card slot 52 has the same structure as the first card slot 12 and can be engaged with the card connector 22. The card connector 22 of the card connector 21 includes a first card connector 23 and a second card connector 24. The first card connector 23 and the second card connector 24 have the same structure. The first card connector 23 and the second card connector 24 are protrusions or at least one protrusion. The first card connector 23 and the second card connector 24 are arranged around the periphery of the card connector 21 and are arranged along the axis or length direction of the card connector 21.

[0058] When the bottle brush 3 is inserted into the box body 1 and the box cover 5 is placed on the nipple brush 4, the first snap-fit ​​part 23 snaps into the first snap-fit ​​groove 12 and the second snap-fit ​​part 24 snaps into the second snap-fit ​​groove 52.

[0059] When the nipple brush 4 is inserted into the box 1, the second snap-fit ​​part 24 snaps into the first snap-fit ​​slot 12.
