Description

Technical Field

[0001] The utility model relates to the technical field of an electric cleaning brush head, in particular to a bending device of a cleaning brush head with variable direction on a brush rod. Background Art

[0002] At present, the bending device of the common cleaning brush head is provided with a plurality of locking grooves on the outer circumference of the adjustment seat, and the locking grooves cooperate with the locking strips meshing therewith. Through the sliding and embedding of the locking grooves and the locking strips, the angle of the brush handle and the transition rod can be changed, so that the brush head on the transition rod also changes accordingly. The locking grooves and the transition rod and the locking strips are coaxial with the brush handle. Only a single locking strip is used to fix the angle. When scrubbing vigorously, there is a problem that the lock strip may break due to excessive force. There is another Chinese utility model patent authorization announcement number CN216875424U "An electric cleaning brush". This model is similar to the above-mentioned prior art.

A single clamping block has the problem of being unable to support the whole process, and the lock strip and the clamping block are coaxial with the brush handle and the handle section. The shear stress on the lock strip and the clamping block may be multiplied by the axial moment. Utility Model Content

[0043] For the bending device of the cleaning brush head of the utility model, please refer to Figures 1 to 3 The cleaning brush 10 is provided with a brush handle 11, and a bending device 20 is provided at the end of the brush handle 11. The bending device 20 is composed of a seat 30, a socket 40 and a button 50. A neck groove 31 is provided in the middle of the seat 30, and a seat groove 32 and a button groove 33 are respectively recessed at both ends of the neck groove 31. A socket 321 is convexly provided in the seat groove 32, and a tongue hole 322 is arranged at the bottom of the seat groove 32 around the side socket 321. A coaxial spring groove 331 and an axis hole 332 are convexly provided in the button groove 33.

[0044] The socket 40 is inserted into the socket groove 32, and the socket 40 is provided with a pivot 41 protruding therefrom. The pivot 41 is surrounded by a tongue 42 protruding from the socket 40. The pivot 41 is inserted into the insertion hole 321, and the tongue 42 is then inserted into the tongue hole 322. The pivot 41 and the tongue 42 pass through the insertion hole 321 and the tongue hole 322 respectively, and both the pivot 41 and the tongue 42 extend out of the neck groove 31.

[0045] The button groove 33 is for the button 50 to be inserted into. The button 50 is provided with a convex shaft 51. The convex shaft 51 is covered with a spring 52 and inserted into the shaft hole 332. The spring 52 is just confined between the spring groove 331 and the shaft hole 332. The convex shaft 51 also extends out of the neck groove 31. By pressing the button 50, the button 50 can slide in the button groove 33.

[0046] A brush head 60 is provided on the support 30, and a brush neck 61 is provided at the lower end of the brush head 60. The brush neck 61 can be inserted into the neck groove 31. The brush neck 61 is provided with a pivot hole 62, and a plurality of slots 63 are arranged around the pivot hole 62. The brush neck 61 is inserted into the neck groove 31, and the socket 40 is inserted into the support groove 32. The pivot 41 passes through the insertion hole 321 and is inserted into the pivot hole 62. At the same time, the tongue 42 passes through the tongue hole 322 and is inserted into the slot 63. In addition, the button 50 is also inserted into the pivot hole 62 and is sleeved with the pivot 41. The socket 40 and the button 50 are screwed together by the screw 43. In this way, the brush head 60 and the bending device 20 are integrated.

[0047] Please also see Figure 2 and Figure 3 By pressing the button 50 to push the socket 40, the tongue 42 is disengaged from the slot 63, so that the brush head 60 is released to rotate around the pivot 41. When the brush head 60 is rotated to an appropriate position, the button 50 is released to allow the tongue 42 to be inserted into another slot 63 again, thereby achieving the effect of changing the angle of the brush head 60 and the brush handle 11 and fixing them.

[0048] Although the inserting tongue 42 is also affected by shear stress in the slot 63 like a cantilever beam, it is not affected by bending moment unlike the prior art because the inserting tongue 42 is transverse to the brush handle 11 and the brush head 60, that is, the inserting tongue 42 is also transverse to the brush neck 61. Therefore, when the brush handle 11 or the brush head 60 applies a moment with the pivot 41 as the center, the inserting tongue 42 is subjected to a large shear stress in the slot 63.

[0049] In order to enhance the strength of the bending device 20, three tongues 42 are added. To match the addition of the tongues 42, three tongue holes 322 are also added. The number of slots 63 is three times the number of tongues 42. If the brush head 60 and the brush handle 11 are rotated, the angles are changed to zero, forty-five and ninety degrees. Figure 4 shown.

[0050] Figure 5 , Figure 6 and Figure 7 The three-dimensional structural diagrams of the brush head 60 and the brush handle 11 are respectively presented at angles of zero degree, forty-five degrees and ninety degrees.

[0051] The above is an explanation of the preferred embodiment of the utility model, and various changes or modifications can be made according to the spirit of the utility model. Therefore, obvious substitutions and modifications that can be made by those skilled in the art will still be incorporated into the patent scope claimed by the utility model.
