[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0028] The utility model provides a kind of cleaning brush of switchable cleaning direction, refer to Figure 1 、 2 Including brush handle 1, brush head rod 2 and connecting rod 3, the brush handle 1 is set with handle sleeve 11, the handle sleeve 11 can be circumferential rotation and up and down sliding on the brush handle 1;The bottom end of the brush head rod 2 is equipped with brush head 21;The two ends of the connecting rod 3 are respectively rotationally connected with the end portion of the brush handle 1, the brush head rod 2, angle limiting mechanism is equipped between the connecting rod 3 and the brush handle 1, the brush head rod 2.

[0029] The cleaning brush has two working states, Figure 3 As shown in the drawing, it is straight handle state, brush handle 1, brush head rod 2, connecting rod 3 are located on the same axis, handle sleeve 11 covers connecting rod 3 and its rotationally connected place with brush handle 1, brush head rod 2, the use of cleaning brush in this state is same as existing straight handle cleaning brush; Figure 4 As shown in the drawing, it is crank state, handle sleeve 11 is completely moved to brush handle 1, connecting rod 3 is rotated to horizontal state, brush handle 1, brush head rod 2 are in vertical state, and the position stability between the three is maintained by angle limiting mechanism. Taking washing cup as an example, user inserts brush head 21 into cup, and holds handle sleeve 11 by hand, so that the cleaning brush in crank state can be rotated with brush head rod 2 as axis, so that brush head 21 can be fully contacted with inner wall of cup, and the cleaning of inner cup is quickly completed.

[0030] Refer to Figure 1 、 5The angle limiting mechanism includes positioning protrusions 31 and positioning arc grooves 13. The positioning protrusions are located at both ends of the connecting rod 3, and the positioning arc grooves 13 are located at the ends of the brush handle 1 and the brush head rod 2. The positioning protrusions 31 on both sides are slidably connected to the corresponding positioning arc grooves 13. The length of the positioning arc groove 13 limits the movement distance of the positioning protrusions 31, thereby limiting the rotation angle of the connecting rod. When the user applies downward pressure to the cleaning brush, the positioning protrusions 31 abut against the ends of the positioning arc grooves 13, thereby maintaining the cleaning brush in a stable crank state.

[0031] See Figure 5 The connecting rod 3 has clearance grooves 32 at both ends, and positioning protrusions 31 are provided on the sidewalls of the clearance grooves 32. The brush handle 1 has a first connecting boss 12 at its end, and the brush head rod 2 has a second connecting boss 22 at its end. The positioning arc groove 13 is provided on the same side surface of the first connecting boss 12 and the second connecting boss 22. Due to the different rotation directions, the positioning arc grooves 13 on the first and second connecting bosses 22 are arranged in opposite directions.

[0032] Preferably, the positioning arc groove 13 is a portion of the arc edge cut out from a circle, and its corresponding circumferential angle is 45°. After folding, the connecting rod 3 is perpendicular to the brush handle 1 and the brush head rod 2 at 90°. At this time, the torque from the brush handle 1 to the brush head rod 2 is the longest, and the user needs to use it with the least effort.

[0033] See Figure 1 The recessed groove 32 is provided with a pivot hole 33, the first connecting boss 12 is provided with a first connecting hole 121, and the second connecting boss 22 is provided with a second connecting hole 221. The first connecting hole 121 and the second connecting hole 221 are respectively provided with a rotating shaft that passes through the pivot hole 33. Through the cooperation of the rotating shaft and the connecting hole, the connecting rod 3 is rotatably connected to the brush handle 1 and the brush head rod 2.

[0034] See Figure 1 A damping groove 14 is provided on the other side surface of the first connecting boss 12 and the second connecting boss 22. A damping plate 15 is provided in the damping groove 14. The damping plate 15 contacts the groove wall of the relief groove 32 to generate rotational resistance, so that the cleaning brush can maintain the crank state even without external force, making it convenient for users to use.

[0035] See Figure 2 , 3 The upper end of the brush head handle 2 is fixed with a stop sleeve 4. In the straight handle state, the bottom end of the grip sleeve 11 is inserted into the stop sleeve 4 to ensure that the position of the grip sleeve 11 is fixed, thereby ensuring that the cleaning brush is in a stable straight handle state. Preferably, the stop sleeve 4 and the grip sleeve 11 are made of soft rubber material.

[0036] With reference to Figure 1 The brush head rod 2 is provided with a stop boss 24 and a plurality of positioning rings 25, the stop sleeve 4 is sleeved on the brush head rod 2, a plurality of positioning grooves are arranged in the stop sleeve 4, and the positioning rings 25 are clamped with the positioning grooves to realize the position fixing of the stop sleeve 4.

[0037] With reference to Figure 1 The hollow cavity 16 with an open top is arranged in the brush handle 1, and a straw brush 17 is inserted in the hollow cavity, and the straw brush is hidden in the hollow cavity in a plug-in mode, that is, the straw brush can be used immediately, and the functional properties of the product are further enriched.

[0038] The preferred embodiments of the utility model are described above, the protection scope of the utility model is not only limited to the above-mentioned embodiments, and all technical solutions belonging to the utility model idea are within the protection scope of the utility model.
