At this time, the second center line X2 of the handle 22 and the first center line X1 of the handle seat 21 form an angle P of 15-50°; with the help of this structure, the user can lift the power source device 2 by using the handle 22; in some preferred embodiments, the angle P is preferably 25-35°.

[0048] In some embodiments of the present application, the power source device 100 further includes a control unit, which includes a control mainboard (not shown) disposed in the housing and a control panel 225 disposed on the handle 22. The control panel 225 is provided with a number of control buttons that can be manipulated.

[0049] In the power source device 100 of the present application, the user can manually switch the handle assembly 2 from the unfolded position to the folded position. In the folded position, the volume of the power source device 100 will be reduced, thereby facilitating the use of the matching surface cleaning equipment.

[0050] See also Fig. 9 , Fig.10 , Fig.11 The surface cleaning device 200 shown is an upright cleaning device, which can be pushed by a user on a hard floor, thereby cleaning the hard floor.

[0051] The surface cleaning device 200 includes a cleaning head portion 40 that can be moved on the surface to be cleaned and has a suction port (not shown in the figure) and a handle body portion 50. The handle body portion 50 includes a support device 51 that is rotatably connected to the cleaning head portion 40 at the lower portion and the above Figure 1-Figure 8 The power source device 100 shown in FIG. The power source device 100 is detachably attached to the support device 51. In this example, the handle body portion 50 can be in an upright storage position relative to the cleaning head portion 40 (see FIG. Fig. 9 ) and a rearward tilted working position.

[0052] The top of the support device 51 is provided with a handle 53. When the power source device 100 is attached to the support device 51, the power source device 100 is attached to the rear of the support device 51 and the handle assembly 2 of the power source device 100 is arranged backward. The entire power source device 100 will be located below the handle 53.

[0053] In some embodiments of the present application, the handle body portion 50 further includes a sewage tank device 52. The sewage tank device 52 is detachably attached to the rear portion of the support device 51 and is located below the power source device 100. The power source device 100 and the sewage tank device 52 are in fluid communication with each other. The air entering the sewage tank device 52 can flow to the suction motor 13 of the power source device 100 and then be discharged to the outside.

[0054] In some embodiments of the present application, the cleaning head portion 40 includes a detachable clean water tank 41. The water in the clean water tank 41 can be supplied to the brush roller 42 at the bottom of the cleaning head portion 40. In other embodiments, the clean water tank 41 can also be arranged at the support device 51.

[0055] The handle body part 50 defines a rear boundary 501; when the handle assembly 2 is in the folded position, the entire power source device 100 is located in front of the rear boundary 501. Fig.10 As shown, when it is necessary to clean the floor at a low place such as under a table, the handle body portion 50 can be rotated backward to a position roughly parallel to the ground. At this time, since the power source device 100 is located as a whole in front of the rear boundary 501, the handle assembly 2 will not touch the ground, so that the movement of the surface cleaning device 200 on the ground will not be restricted.

[0056] When the power source device 100 needs to be removed from the surface cleaning device 200, the handle body portion 50 is rotated to a storage position perpendicular to the ground (this position is also the position where the device stops working) for manually operating the handle assembly 2 so that the handle assembly 2 is switched to the unfolded position, such as Fig.11 As shown, at this time, the user can hold the handle 22 to easily separate the power source device 100 from the supporting device 51 .

[0057] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present application. Without departing from the spirit and scope of the present application, the present application may have various changes and improvements, and the scope of protection required by the present application is defined by the attached claims, description and their equivalents.
