Although the screw fixing method has a stable connection, it is cumbersome to operate and requires the user to tighten the screws manually. In addition, the working head is prone to fall off due to loose screws. 2. Interference plug-in type, the connection is not firm enough and is easy to fall off. Summary of the invention

[0004] Based on this, the present application provides a working head connection structure of a vacuum cleaner to solve one of the above-mentioned technical problems.

[0005] The technical solution adopted by the present application to solve its technical problems is: a vacuum cleaner working head connection structure, including: a connecting part, fixed to the air outlet of the vacuum cleaner; a locking mechanism: installed in the internal cavity of the connecting part, including a first rack, a second rack, a gear, a spring and a locking block, used to lock and unlock the vacuum cleaner working head; when the vacuum cleaner working head is inserted into the connecting part, the locking block is embedded in the vacuum cleaner working head through the through hole on the working head. If unlocking is to be done, press the button fixed on the first rack to unlock, and the button is reset by the spring fixed on the first rack.

[0006] In some embodiments, the first rack is installed on the left side of the gear, and the second rack is installed on the right side of the gear.

[0007] In some embodiments, the upper portion of the first rack is connected to the button, and the lower portion is connected to the spring, and the lower end of the spring is fixed to the lower portion of the cavity.

[0008] In some embodiments, a locking block is fixed to the lower portion of the second rack.

[0009] In some embodiments, the lower end of the locking block is sharpened on one side close to the working head connection direction.

[0010] In some embodiments, the connecting portion is rounded at one end close to the vacuum cleaner working head.

[0011] In some embodiments, the locking mechanism can be adapted to a variety of different styles of vacuum cleaner working heads.

[0012] In some embodiments, the connecting portion is made of plastic, and the locking mechanism is made of metal.

[0013] In some embodiments, the locking mechanism has two sets symmetrically mounted on the connecting portion.

[0014] The beneficial effect of the present application is that the design of the connection structure makes it easier to replace the working head of the vacuum cleaner. The user only needs to insert the working head of the vacuum cleaner into the connection part, and the locking block can be embedded into the working head of the vacuum cleaner through the through hole on the working head to achieve quick locking. If the working head needs to be replaced, just press the button fixed on the first rack, and it can be easily unlocked through the cooperation of the gear rack. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to achieve. When the combination of technical solutions is contradictory or cannot be achieved, it should be considered that the combination of such technical solutions does not exist and is not within the scope of protection of this application.
