[0002] A handheld vacuum cleaner, as the name implies, is a small vacuum cleaner that can be held directly in the user's hand. This type of vacuum cleaner is usually designed to be very compact and lightweight, making it easy to carry and use. Due to its portability, handheld vacuum cleaners are particularly suitable for cleaning vehicle interiors, furniture surfaces, keyboards, appliances, and other hard-to-reach places.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] The utility model provides a technical solution: Figure 1-Figure 4As shown, in the present embodiment, a quick-change mechanism for a suction nozzle of a handheld vacuum cleaner is provided, comprising: a quick-release mechanism 1, the quick-release mechanism 1 comprising a vacuum cleaner body 11, a pipe 12 is arranged at the bottom of the vacuum cleaner body 11, a mounting pipe 13 is arranged at one end of the pipe 12 away from the vacuum cleaner body 11, a connecting pipe 14 is arranged at one end of the mounting pipe 13 away from the pipe 12, a suction nozzle body 31 is fixedly connected to one end of the connecting pipe 14 away from the mounting pipe 13, the bottom of the vacuum cleaner body 11 is fixedly connected to one side of the top of the pipe 12, one end of the mounting pipe 13 is butted with one end of the pipe 12 away from the vacuum cleaner body 11, four positioning sliders 15 are arranged in an outer annular array near one end of the connecting pipe 14 near the mounting ring, positioning holes 16 are provided on both sides of the outer side of the connecting pipe 14 near one end of the mounting ring, four positioning grooves 17 are provided in an annular array on the inner wall of the mounting pipe 13, one end of the connecting pipe 14 away from the suction nozzle body 31 is butted in the mounting pipe 13, one side of the four positioning sliders 15 near the connecting pipe 14 is fixedly connected to the outside of the connecting pipe 14, and the positioning The outside of the positioning slide block 15 is slidably connected to the inner wall of the positioning groove 17, and the grooves opened on both sides of the outside of the mounting tube 13 are provided with mounting blocks 18, and the two mounting blocks 18 are provided with a wrench 19 on the opposite sides. A movable rod 110 is provided inside the two mounting blocks 18. The grooves opened on both sides of the outside of the mounting tube 13 are fixedly connected with the mounting blocks 18, and the side of the mounting block 18 away from the mounting tube 13 contacts the side of the wrench 19 close to the mounting block 18, and one end of the movable rod 110 is movably connected to the inside of the wrench 19. A return spring 111 is provided on the outside of the two movable rods 110, and a positioning block 112 is provided on the end of the two movable rods 110 away from the block 19. The other end of the movable rod 110 passes through the slot opened on one side of the mounting block 18 and is fixedly connected to the inner circle of the return spring 111 at one end of the positioning block 112. The other end of the positioning block 112 is clamped with the inner wall of the positioning hole 16. The end of the return spring 111 close to the block 19 is fixedly connected to the side of the inner wall of the mounting shell away from the positioning block 112, and an auxiliary mechanism 2 is provided on the top of the pipe 12.

[0024] In this embodiment, when the working user needs to remove the suction nozzle body 31 from the vacuum cleaner, the lever block 19 can be pulled. When the lever block 19 is pulled, the movable rod 110 and the positioning block 112 will be moved in the force direction, so that the positioning block 112 will move to the slot opened by the mounting block 18. As the positioning block 112 moves, the return spring 111 will be squeezed, and the return spring 111 will shrink and deform. At the same time, the positioning block 112 will also be disengaged from the positioning hole 16, and then the connecting tube 14 and the suction nozzle body 31 will be fixedly limited in contact with the vacuum cleaner body 11. By pulling the connecting tube 14, the positioning slider 15 slides in the positioning groove 17, so that the connecting tube 14 and the suction nozzle body 31 will be removed, and the positioning groove 17 and the positioning slider 15 can provide a positioning effect for the connecting tube 14 to ensure that the connecting tube 14 can be smoothly installed during the installation process.

[0025] like Figure 1-Figure 4 As shown, the auxiliary mechanism 2 includes a collecting shell 21, and a dust storage port 23 is docked in a slot opened on one side of the bottom of the collecting shell 21, and the bottom end of the dust storage port 23 is docked with a slot opened on the top of the pipe 12. Four blocks 22 are fixedly connected in an annular array at one end of the collecting shell 21 close to the vacuum cleaner body 11, and four clamping grooves 24 are opened in an external annular array of the vacuum cleaner body 11 close to one end of the collecting shell 21, and the clamping blocks 22 are clamped with the clamping grooves 24.

[0026] In this embodiment, when the dust in the collection shell 21 needs to be removed and cleaned, the block 22 can be pressed accordingly, and the block 22 will be recessed into the card slot 24, and the collection shell 21 will contact the limit fixation. By pulling the collection shell 21, the collection shell 21 can be removed to clean the dust and impurities inside it, avoiding the traditional complicated disassembly steps.

[0027] The utility model provides a quick-change mechanism for the suction nozzle of a handheld vacuum cleaner, and the specific working principle is as follows:

[0028] When the working user needs to remove the suction nozzle body 31 from the vacuum cleaner, he pulls the pull block 19. When it is pulled, it will apply force to the movable rod 110 and the positioning block 112, causing them to move in the direction of the force. This movement will cause the positioning block 112 to move into the slot provided in the mounting block 18. As the positioning block 112 moves, the return spring 111 will also be squeezed. This squeezing will cause the return spring 111 to deform and shrink. At the same time, the positioning block 112 will also disengage from the positioning hole 16. In this way, the connecting tube 14 and the suction nozzle body 31 can be fixedly limited in contact with the vacuum cleaner body 11. Next, by pulling the connecting tube 14, the positioning slider 15 can slide in the positioning groove 17. This sliding will cause the connecting tube 14 and the suction nozzle body 31 to be removed.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
