The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the utility model, and cannot be understood as limitations on the utility model.

[0027] like Figure 1 As shown, a cleaning device of one embodiment of the utility model comprises a body 1 and a cleaning head 2 connected to the body 1, and the cleaning head 2 and the body 1 are connected by a hose 11. The body 1 is generally provided with a suction motor for generating a suction airflow, and the cleaning head 2 is provided with a suction port 211, and the suction port 211 and the suction motor are connected by a suction pipe. When in use, the user only needs to hold the cleaning head 2 and move along the surface to be cleaned to suck the dirt on the surface to be cleaned into the body 1. The cleaning head 2 is also provided with cleaning parts 212 such as bristles, roller brushes, and steam nozzles, and cleaning parts 212 of different structures can achieve different cleaning effects. In this embodiment, the cleaning head 2 comprises a handle portion 22 for the user to hold and a cleaning portion 21 connected to the handle portion 22, and the suction port 211 and the cleaning part 212 are both arranged on the cleaning portion 21. The cleaning portion 21 and the handle portion 22 are detachably connected, and objects can be cleaned in different ways by replacing different cleaning portions 21 on the handle portion 22.

[0028] like Figure 2 , Figure 4 and Figure 6 As shown, the cleaning part 21 and the handle part 22 are detachably connected by a connecting device, and the connecting device includes a first connecting member 3 and a second connecting member 5 respectively arranged on the cleaning part 21 and the handle part 22. The first connecting member 3 and the second connecting member 5 can be connected to each other, so as to fix the cleaning part 21 and the handle part 22. In this embodiment, the first connecting member 3 is arranged on the handle part 22, and the first connecting member 3 includes a carrier 31 and an elastic member 32 connected to the carrier 31, and the carrier 31 has a hollow installation space 311, the elastic member 32 is located in the installation space 311, and one end of the elastic member 32 is connected to the carrier 31. The end where the elastic member 32 is connected to the carrier 31 is the first end 321, and the end of the elastic member 32 away from the first end 321 is the second end. A control member 4 for user control is arranged on the second end, and pressing the control member 4 can cause the elastic member 32 to rotate relative to the carrier 31 with the first end 321 as the rotating shaft, and when the external force applied to the control member 4 disappears, the control member 4 can return to the initial position.

[0029] like Figure 2 and Figure 4 As shown, in this embodiment, the control member 4 is also the first clamping member on the first connecting member 3, and the second connecting member 5 is also provided with a second clamping member that is clamped and matched with the first clamping member. In this embodiment, the outer shell of the cleaning part 21 is the second connecting member 5, and the second clamping member is set to penetrate the positioning hole 51 set on the outer shell of the cleaning part 21. During installation, one end of the handle part 22 is inserted into the outer shell of the cleaning part 21. After installation, the control member 4 is clamped in the positioning hole 51, so as to achieve the fixed connection between the handle part 22 and the cleaning part 21. When the cleaning part 21 needs to be disassembled, the user only needs to press the control member 4 through the hollow positioning hole 51, and then pull out the cleaning part 21, so that the control member 4 is disengaged from the positioning hole 51, thereby unlocking the first clamping member and the second clamping member, so as to remove the cleaning part 21 from the handle part 22.

[0030] like Figure 6 As shown, specifically, the first end 321 of the elastic member 32 can be rotatably arranged on the carrier 31 in the form of an axis connection, or as shown in the drawings of this embodiment, the first end 321 can be directly fixed on the carrier 31, and the elastic member 32 is elastically deformed by pressing the operating member 4, so that it can rotate with the first end 321 as the axis. It is preferred to set the elastic member 32 and the carrier 31 to be integrally formed, which is convenient for production and can reduce production costs. Figure 5As shown, in this embodiment, a mounting groove 221 is provided on the outer wall of the handle portion 22, and the carrier 31 is installed in the mounting groove 221, and can be installed in a conventional manner such as ultrasonic welding, clamping or screw fixing. In other embodiments not shown in the figures, the carrier 31 can also be integrally formed with the outer shell of the handle portion 22, that is, the elastic member 32 is provided on the outer shell of the handle portion 22, and in this case, the outer shell of the handle portion 22 is the first connecting member 3.

[0031] Continue to refer to Figure 4 and Figure 6 Since the first end 321 is directly fixed on the carrier 31, the operating member 4 is arranged at the second end away from the first end 321, so that the user can press the operating member 4, thereby facilitating the removal of the cleaning part 21. The operating member 4 protrudes from the surface of the elastic member 32, so that it can be located in the positioning hole 51 after installation, which not only has a positioning effect, but also is convenient for the user to press. In this embodiment, an end face of the operating member 4 close to the cleaning part 21 is arranged as an inclined surface 41, so that when the handle part 22 is inserted into the outer shell of the cleaning part 21, the outer shell of the cleaning part 21 can press the operating member 4 downward along the inclined surface 41, and when the operating member 4 moves to the position of the positioning hole 51, it can rebound and snap into the positioning hole 51, which is convenient for installation. The upper portion of the operating member 4 on one end surface close to the handle portion 22 is configured as an inclined surface or a smooth rounded corner. Thus, when disassembling, the user only needs to press the operating member 4 so that the inclined surface or the rounded corner is pressed down to contact the side wall of the positioning hole 51, and then pull out the handle portion 22 to easily remove the cleaning portion 21.

[0032] Since the operating member 4 also serves as the first clamping member, the operating member 4 needs to rotate at a larger angle when unlocking the cleaning portion 21 and the handle portion 22; since the first end 321 of the elastic member 32 is fixedly connected to the carrier 31, the larger rotation angle makes it easy for the elastic member 32 to break at the first end 321 during long-term use. Figure 6As shown, in the present embodiment, a first bending portion 322 is further provided on the elastic member 32 between the first end 321 and the operating member 4, and the rotation direction of the elastic member 32 when the operating member 4 is pressed is taken as the first direction, and the first bending portion 322 is to bend toward the first direction; in this way, when the operating member 4 is pressed, the elastic member 32 can also bend at the first bending portion 322, thereby increasing the rotation angle of the operating member 4; in this way, the stress concentration of the elastic member 32 at the first end 321 can be reduced, so that the connecting device is not easily damaged during long-term frequent use, and the first bending portion 322 allows the user to press the operating member 4 to the corresponding angle with only a small force, thereby unlocking the cleaning portion 21 and the handle portion 22, which is convenient for the user to frequently disassemble and assemble the cleaning portion 21 and the handle portion 22. Furthermore, in order to further prevent stress concentration and facilitate user pressing, multiple bending portions can be set between the first end 321 and the operating member 4. For example, in this embodiment, a second bending portion 323 is also set between the first bending portion 322 and the operating member 4. The second bending portion 323 can strengthen the strength of the first bending portion 322 and prevent the elastic member 32 from breaking at the first bending portion 322.

[0033] In other embodiments not shown in the figures, the operating member 4 is arranged at the second end, but does not act as the first clamping member, but a first clamping member is additionally arranged between the first end 321 and the operating member 4 to cooperate with the second clamping member on the second connecting member 5; in this embodiment, the first end 321 can still be fixedly connected to the carrier 31, and one or more bending parts can be arranged between the first end 321 and the first clamping member to facilitate pressing and improve strength. In addition, the connecting device in the present application can also be used at other positions on the cleaning device besides the cleaning head 2.

[0034] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
