Description

Technical Field

[0001] This utility model relates to the field of daily necessities, and in particular to a brush with a rotatable brush head. Background Technology

[0002] Currently, most shoe brushes on the market adopt a one-piece fixed structure, with a rigid connection between the brush head and the handle, making rotation or angle adjustment impossible. For example, Chinese Patent Publication No. CN109008176A discloses a shoe brush including a brush head and a handle, wherein the brush head and handle are fixedly connected, and a bending part is provided on the handle. In actual use, the above-mentioned shoe brush may have the following inconveniences: when cleaning the upper and lower surfaces of the shoe's inner cavity, the heel, or complex curved surfaces, the fixed brush head angle is easily obstructed, leading to inconvenience in operation and even ineffective cleaning of hard-to-clean areas. Furthermore, because the brush head angle is not adjustable, users need to frequently adjust their grip, which can easily cause hand fatigue and a poor user experience over time.

[0003] In view of this, the present invention proposes a brush with a rotatable brush head to solve the above problems. Utility Model Content

The other end of the locking component 4 is provided with a slider 41 that can pass through the through hole 231. The connecting seat 3 is provided with a locking hole 32 for accommodating the slider 41. Specifically, the slider 41 has an arc surface to facilitate the slider 41 sliding out of the locking hole 32.

[0029] The locking component 4 includes two translation parts 42 arranged one in front of the other and a connecting part 43. The connecting part 43 extends in the front-back direction, and the translation parts 42 extend in the left-right direction. The slider 41 is located at the right end of the translation parts 42. The left ends of the two translation parts 42 are connected by the connecting part 43. The left side of the connecting part 43 is connected to the spring 24. Fig. 2 As shown, the right end of the housing 23 has two through holes 231, which are located at the front and rear of the rotating shaft 22, respectively. The connecting seat 3 has two locking holes 32. The elastic locking assembly can lock the brush head 2 after it rotates 180°.

[0030] like Fig. 1 As shown, the translation part 42 has a limiting protrusion 44 on the left side on its outer periphery. The width of the limiting protrusion 44 is greater than the diameter of the through hole 231. The limiting protrusion 44 is used to limit the extension distance of the translation part 42. The receiving cavity is provided with a limiting block 235 for limiting the movement distance of the translation part 42 into the receiving cavity.

[0031] The rotating hole 31 is provided with an arc-shaped step 311, and the outer shaft of the rotating shaft 22 is provided with a positioning protrusion 221 that rests on the arc-shaped step 311. The positioning protrusion 221 is used to cooperate with the arc-shaped step 311 to limit the rotation angle of the rotating shaft 22.

[0032] like Fig. 2 As shown, the movable connection structure includes a rotating sleeve 33 formed on the right end of the rotating hole 31. The rotating sleeve 33 has an opening 331 for its deformation under force. The outer side of the rotating shaft 22 has a slot 222, and the inner side of the rotating sleeve 33 has a retaining strip 332. The rotating shaft 22 passes through the rotating hole 31 and the rotating sleeve 33 in sequence. During this process, the rotating sleeve 33 will deform. The retaining strip 332 connects with the slot 222, so that the rotating shaft 22 can rotate without disengaging from the rotating hole 31. The movable connection structure is simple.

[0033] The left end of the brush handle 1 is provided with a mounting groove 11 for accommodating the connecting seat 3. The mounting groove 11 is provided with a screw hole 12, and the connecting seat 3 is provided with a countersunk hole 34. The screw hole 12 and the countersunk hole 34 are connected by a screw 35. The locking hole 32 communicates with the countersunk hole 34, and the countersunk hole 34 is located to the right of the locking hole 32, thus optimizing the design position of the screw hole 12 and the countersunk hole 34.

[0034] The housing 23 is formed by the lower half-shell 233 and the upper cover 234 being connected relative to each other, and the elastic locking component is disposed in the lower half-shell 231.

[0035] The working principle of this utility model is as follows: Fig. 3 As shown, the brush head 2 initially has its bristles 21 facing downwards, used for cleaning the surface of the shoe and the bottom of the shoe's inner cavity. When the user applies an external force to drive the brush head 2 to rotate, the slider 41 slides out of the locking hole 32, and at the same time, the spring 24 is compressed and then returns to its original position. The user continues to rotate the brush head 2 around the pivot 22 until the positioning protrusion 221 is blocked. The brush head 2 rotates 180°, and the slider 41 slides into another locking hole 32. At this time, the bristles 21 of the brush head 2 face downwards, used for cleaning the top surface of the shoe's inner cavity and the heel.
