[0040] Please refer to Figures 1 to 7 As shown, it shows the specific structure of an embodiment of the utility model.

[0041] A vacuum cleaner nozzle includes a nozzle head 10, a flexible tube 20 and a nozzle body 30. The flexible tube 20 is bendable, retractable and rotatable, and the flexible tube 20 is preferably a silicone tube. The nozzle head 10 is connected to one end of the flexible tube 20, and the nozzle body 30 is connected to the other end of the flexible tube 20. The nozzle head 10 and the nozzle body 30 are rotatably connected through a rotating member. Specifically, the rotating member includes a ball head 40 and a sleeve 50 that are relatively rotatably connected, and the sleeve 50 is covered on the outside of the ball head 40; the ball head 40 is arranged at one end of the nozzle body 30 and extends into the flexible tube 20, and the sleeve 50 is arranged at one end of the nozzle head 10 and extends into the flexible tube 20. In this way, the nozzle head 10 can be rotated relative to the nozzle body 30 through the bendability of the flexible tube 20 itself and the rotation of the rotating member. In this way, the nozzle head 10 can be flexibly turned and extended into a narrow space for effective dust collection.

[0042] In this embodiment, the nozzle head 10 includes a connector 11, a straw 12 and a nozzle 13. One end of the connector 11 is connected to the flexible tube 20, one end of the straw 12 extends into the other end of the connector 11, and the nozzle 13 is movably mounted on the other end of the straw 12 along the length extension direction of the straw 12. A brush (not shown in the figure) is provided at the end of the nozzle 13 away from the connector 11. A rotatable pressing member 60 is provided on the nozzle 13. A clamping portion 61 is provided on one end of the pressing member 60 facing the nozzle 13. A plurality of clamping grooves 121 are provided on the side of the straw 12 facing the pressing member 60. The plurality of clamping grooves 121 are arranged in sequence along the length extension direction of the straw 12. The clamping portion 61 can be selectively clamped into or out of the corresponding clamping groove 121 as the pressing member 60 rotates. In this way, the user can extend the brush out of the end of the straw 12 by moving the suction head 13 according to usage needs, which helps the user to use the brush to clean dust, making it highly practical. In addition, through the combined design of the clamping portion 61 and the clamping groove 121, the suction head 13 can be firmly positioned on the straw 12 to avoid the suction head 13 sliding relative to the straw 12.

[0043] In this embodiment, a fixing portion 131 is provided on the suction head 13, and a positioning cavity 132 is provided on the fixing portion 131. Rotation holes 133 are provided on two pairs of side walls of the positioning cavity 132. Rotation shafts 62 are provided on two pairs of side walls of the pressing member 60. The pressing member 60 is assembled in the positioning cavity 132. The rotation shaft 62 can be rotatably positioned in the rotation hole 133. A clearance hole 134 is provided at the bottom of the positioning cavity 132. The clearance hole 134 passes through the interior of the suction head 13. The clamping portion 61 passes through the clearance hole 134. The clearance hole 134 makes way for the clamping portion 61, so that the clamping portion 61 can be smoothly clamped into the clamping slot 121 or detached from the clamping slot 121. In addition, a positioning column 63 is provided on the other end of the push member 60 facing the side of the suction head 13, and the positioning column 63 is connected to a spring, and one end of the spring is limited by the bottom of the positioning cavity 132. In this way, when the other end of the push member 60 is pressed, the push member 60 rotates under the cooperation of the rotating shaft 62 and the rotating hole 133 to drive the clamping portion 61 to disengage upward from the clamping slot 121. Then, when the suction head 13 is pushed to the position of another clamping slot 121, the push member 60 is released. The push member 60 rotates under the action of the restoring elastic force of the spring to drive the clamping portion 61 to clamp downward into another clamping slot 121, and the clamping portion 61 continues to remain clamped in the clamping slot 121 under the action of the tension of the spring.

[0044] In this embodiment, a first limiting protrusion 122 and a second limiting protrusion 123 are provided on the side of the suction tube 12 facing away from the pressing member 60. The first limiting protrusion 122 and the second limiting protrusion 123 are arranged in sequence along the length extension direction of the suction tube 12. A limiting wall 135 is provided on the end of the inner wall of the suction head 13 facing away from the connecting member 11. The limiting wall 135 is limited by the first limiting protrusion 122, and the end of the suction head 13 facing the connecting member 11 is limited by the second limiting protrusion 123. In this way, through the combined design of the first limiting protrusion 122, the second limiting protrusion 123 and the limiting wall 135, the movement of the suction head 13 can be limited within a specific range, so that the brush can protrude from the end of the suction tube 12 to clean dust, and can be retracted into the end of the suction tube 12 to avoid interfering with the suction operation of the suction tube 12.

[0045] In this embodiment, the end of the flexible tube 20 close to the nozzle head 10 is provided with a first positioning connection portion 21, and the end of the nozzle head 10 close to the flexible tube 20 is provided with a second positioning connection portion 14, and the first positioning connection portion 21 is adaptively connected to the second positioning connection portion 14. The end of the flexible tube 20 close to the nozzle body 30 is provided with a third positioning connection portion 22, and the end of the nozzle body 30 close to the flexible tube 20 is provided with a fourth positioning connection portion 31, and the third positioning connection portion 22 is adaptively connected to the fourth positioning connection portion 31. In this way, through the combined design of the first positioning connection portion 21, the second positioning connection portion 14, the third positioning connection portion 22 and the fourth positioning connection portion 31, the connection between the flexible tube 20 and the nozzle head 10 and the nozzle body 30 can be achieved.

[0046] In this embodiment, an annular positioning protrusion 23 is provided at one end of the flexible tube 20 close to the nozzle head 10, and an annular positioning groove 15 is provided at one end of the nozzle head 10 close to the flexible tube 20, and the annular positioning protrusion 23 is positioned in the annular positioning groove 15. The sleeve 50 is convexly provided at one end of the nozzle head 10, and the annular positioning groove 15 is located at the periphery of the sleeve 50. Specifically, the second positioning connection portion 14, the annular positioning groove 15 and the sleeve 50 are all provided at one end of the connector 11.

[0047] In summary, the design focus of the utility model is that it mainly connects a flexible tube between the nozzle head and the nozzle body, and makes the nozzle head and the nozzle body rotatably connected through a rotating member, so that the nozzle head can be rotated relative to the nozzle body through the bendability of the flexible tube itself and the rotation of the rotating member, so that the nozzle head can be flexibly turned to extend into a narrow space for effective dust collection; and a brush is arranged on the end of the nozzle, and the nozzle head is movably installed on the other end of the suction pipe along the length extension direction of the suction pipe, and the nozzle head is moved to the nozzle head. A rotatable pressing piece is provided, and a clamping portion is provided on one end of the pressing piece facing the side of the suction head, and a plurality of clamping grooves are provided on the side of the straw facing the pressing piece, so that the clamping portion can be selectively clamped into or disengaged from the corresponding clamping groove as the pressing piece rotates. In this way, the user can extend the brush out of the end of the straw by moving the suction head according to usage requirements, which helps the user to use the brush to clean dust, making it highly practical. In addition, through the combined design of the clamping portion and the clamping groove, the suction head can be firmly positioned on the straw to avoid the suction head sliding relative to the straw.
