Dust collection box 2 one side is connected with the lateral wall of dust removal case through hasp spare (not shown in the drawing), and the hasp spare can adopt the mature product structure on the market, connects one side lateral wall between dust collection box 2 and the dust removal case 1 through hasp spare mount pad 24 (upper and lower two parts), 2 opposite sides of dust collection box pass through fastener structure and another lateral wall swing joint of dust removal case 1, and the design also adopts the hasp spare to realize being connected of opposite side lateral wall between dust collection box 2 and the dust removal case 1 before, but this kind of mode needs two people's cooperation to carry out the dismouting, wastes time and energy. The buckle structure is adopted to replace and just can overcome this problem, specifically, the buckle structure includes buckle 23 and button 22, buckle 23 one end and dust removal case 1 lateral wall fixed connection, the other end are close to dust collection box 2, indicate that buckle 23 is roughly the L type promptly, and buckle 23 one end is connected with dust removal case 1, and the other end is close to dust collection box 2. The buckle 23 is close to the one end of dust collection box 2 and extends towards dust collection box 2 and has a support boss, and the support boss is preferably the level and arranges a short strut, and processing has the pinhole on this support boss, and the form of pinhole can be processed on the surface of supporting the boss or inside supporting the boss, can be the form of blind hole or through-hole, and in this embodiment, the pinhole lies in the upper surface that supports the boss and is close to buckle 23's table wall department, and the axis of pinhole is parallel to each other with the lateral wall that buckle 23 is connected to dust removal box 1. One end of the buckle 22 is fixedly connected with the dust collection box 2, the buckle 22 may be a single plate or a combination of two parallel plates, where the combination of two parallel plates is adopted, a pin rotatably inserted into a pin hole is formed at the other end of the buckle 22, the pin and the whole buckle 22 are combined into a structure of a substantially U-shaped body, and the pin rotatably inserted into the pin hole can enable the dust collection box 2 to swing up and down by rotating relative to the dust collection box 1, in another embodiment, by changing the axial direction of the pin hole, the dust collection box 2 can also swing left and right by rotating relative to the dust collection box 1.

Returning to the embodiment, an operating handle 4 is installed on one side of the dust collection box 2 far away from the fastener structure, the lower part of the operating handle 4 is hinged to the dust collection box 2 through a pin-type hinge or a hinge base 41, and a limit collision can be formed between the lower end of the operating handle 4 and the side wall of the dust collection box 2, that is, after the operating handle 4 is rotated for a certain angle, the lower end of the operating handle 4 abuts against the side wall of the dust collection box 2, so that the maximum rotation angle of the operating handle 4 is limited. In order to fix or position the operating handle 4 in an unused state, a locking mechanism 42 for fixing the upper part of the operating handle 4 is arranged on the side wall of the dust removing box 1, the locking mechanism 42 can be a structure such as a quick fastener, a bolt or a bolt, the locking mechanism 42 comprises two lugs, a movable bolt is inserted between the two lugs, a corresponding pin hole is processed in the operating handle 4, and the bolt passes through the pin hole of one lug and the operating handle 4 and then passes through the other lug so as to realize the locking function of the operating handle 4. When the dust collection box 2 needs to be disassembled, the fastener of the fastener mounting seat 24 is taken down firstly, then the locking mechanism 42 is disassembled, so that the upper end of the operating handle 4 can rotate around the hinged support 41 towards the direction far away from one side of the dust collection box 1, when one side of the dust collection box 2 is separated from one side of the dust collection box 1, the whole operating handle 4 is supported by hands in the process, the dust collection box 2 is slowly put down, the walking wheels 21 are grounded, then the dust collection box 2 is pried by utilizing the lever principle to enable the pin body of the fastener 22 to be separated from the pin hole of the buckle plate 23, and then the dust collection box 2 is pulled out to complete the disassembling operation of the dust collection box 2. The disassembly process can be completed by one-man operation, the mode that the ash can be unloaded only by the cooperative operation of two persons is changed, the convenience and the operability of the ash unloading are greatly improved, and the whole process can be carried out anytime and anywhere and is very convenient.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention. It should be noted that structures or components illustrated in the drawings are not necessarily drawn to scale, and descriptions of well-known components and processing techniques and technologies are omitted to avoid unnecessarily limiting the invention.
