To solve this problem, as shown in fig. 6 and 7, in the present embodiment, the main body 100 of the cleaning device includes a locking mechanism 3 and a flexible handle 9, wherein the locking mechanism 3 is disposed in the accommodating space and can lock the cover body 2 with the machine body 1; one end of the flexible handle 9 is connected with the locking mechanism 3, the other end of the flexible handle 9 penetrates through the cover body 2 or the machine body 1 and is positioned outside the main machine 100, and the locking mechanism 3 can be triggered by pulling the flexible handle 9 so as to unlock the cover body 2 and the machine body 1.

The locking mechanism 3 is arranged in the accommodating space formed by the machine body 1 and the cover body 2, and only a small part of the flexible handle 9 is exposed outside the main machine 100 of the cleaning device, so that the attractiveness of the overall appearance surface of the main machine 100 of the cleaning device can be kept; the locking mechanism 3 is positioned in the accommodating space formed by the machine body 1 and the cover body 2, so that the phenomenon that the locking mechanism 3 cannot be normally locked due to the fact that dust raised when the cleaning device is used falls on the locking position of the locking mechanism 3 can be avoided; in addition, the unlocking of the locking mechanism 3 is triggered by pulling the flexible handle 9, so that even if the cleaning device collides with other furniture during use, the abnormal unlocking of the locking mechanism 3 cannot be caused, thereby ensuring that the cleaning device can be normally used and prolonging the service life of the cleaning device.

Further, as shown in fig. 7, the locking mechanism 3 includes a first locking member 31, a second locking member 33 and an elastic member 32, the first locking member 31 is disposed on the machine body 1; the second locking piece 33 is pivoted with the cover body 2 and is connected with the flexible handle 9; the elastic member 32 has two states, namely a first state and a second state, and when the elastic member 32 is in the first state, the elastic member 32 locks the first locking member 31 and the second locking member 33; pulling the flexible handle 9 brings the elastic element 32 into the second state, unlocking the first locking element 31 and the second locking element 33.

Specifically, the first locking member 31 includes a first hook portion 311 provided on the machine body 1; the second locking member 33 includes a mounting portion 331 and a second hook portion 332, the mounting portion 331 is pivotally connected to the cover 2, and the elastic member 32 is disposed between the mounting portion 331 and the cover 2; the second hook portion 332 is connected to the mounting portion 331, and when the elastic member 32 is in the first state, the elastic member 32 rotates the mounting portion 331 toward the first direction, so that the second hook portion 332 is engaged with the first hook portion 311; pulling the flexible handle 9 rotates the mounting portion 331 toward a second direction compressing the elastic member 32 to separate the second hook portion 332 from the first hook portion 311, the second direction being opposite to the first direction. When a user pulls the flexible handle 9, the flexible handle 9 can drive the second hook portion 332 to rotate towards the second direction through the mounting portion 331, so that the second hook portion 332 is separated from the first hook portion 311, and the user can plate the cover body 2 and rotate the cover body in a direction away from the machine body 1, so that the user can take out the dust bag 10 conveniently; when a user puts the dust bag 10 with cleaned dust and impurities into the accommodating space again, the user can move the cover 2 and make it rotate in a direction close to the machine body 1, after the cover 2 is covered on the machine body 1, the second hook part 332 contacts with the first hook part 311 and mutually extrudes, so that the second hook part 332 and the mounting part 331 rotate in a second direction relative to the cover 2, and the elastic part 32 is compressed, when the upper surface of the second hook part 332 rotates to be positioned below the lower surface of the first hook part 311, under the action of the elastic restoring force of the elastic part 32, the mounting part 331 can rotate in the first direction to be clamped on the first hook part 311, so that the automatic locking of the locking mechanism 3 is realized, the operation steps of the user are simplified, and the situation of inconvenient locking caused by the fact that the locking mechanism 3 is positioned in the accommodating space formed by the machine body 1 and the cover 2 is avoided. It can be understood that, when the locking mechanism 3 is in the locked state, the elastic member 32 is still in the second state to exert a certain pressure on the mounting portion 331, so as to ensure the stability of the locked state of the second hook portion 332 and the first hook portion 311.

In the present embodiment, the elastic member 32 is a spring, which has the advantages of large elastic restoring force and low manufacturing cost. Of course, in other embodiments, the elastic member 32 may be a rubber block or other structures having elastic restoring force. It should be noted that, when the elastic member 32 is in the first state, the elastic member 32 is in a compressed state to provide a sufficient locking force for the first locking member 31 and the second locking member 33; when the elastic member 32 is in the second state, the elastic member 32 is in a compressed state to provide a sufficient restoring force for subsequent locking of the first locking member 31 and the second locking member 33.

In addition, as shown in fig. 7, the flexible handle 9 is soft, so that the flexible handle 9 can be placed on the cover body 2 or the machine body 1 without affecting the normal use of the cleaning device. In addition, in the process that the user pulls or loosens the flexible handle 9 repeatedly, although the flexible handle 9 frequently rubs against the cover body 2, the outer surface of the cover body 2 or the machine body 1 is not damaged by the flexible handle 9 due to the soft texture of the flexible handle 9. Specifically, the flexible handle 9 may be made of cotton cloth, non-woven fabric, or fiber cloth, which is soft, has high toughness and sufficient resistance, and can be used for a long time.
