Embodiment Construction
[0039] The vacuum cleaner with the automatic retractable support device of the present invention will be described in detail below with reference to the accompanying drawings and embodiments. In the drawings of the present invention, the same components as those in the prior art use the same symbols.
[0040] figure 2 It is a bottom view structural view of the bottom shell of the horizontal vacuum cleaner of the present invention. The body of the horizontal vacuum cleaner includes parts such as a front cover, a rear cover and a bottom case 1 . Such as figure 2 As shown, the front end of the bottom case 1 is provided with a hose connector 4, and the lower part of the front part of the bottom case 1 is provided with casters 2 which are convenient for changing directions. The front cover is connected to the bottom case 1 through the connecting device at the front end. The front half of the bottom case 1 below the front cover forms a dust collection box for collecting inhale...

The invention discloses a dust collector provided with an automatic support device for put-away and release. The dust collector comprises a bottom shell. A dust collecting device and a fan motor unit are arranged inside the bottom shell. A square hole is formed in the middle of a bending part of the back end of the bottom shell. The automatic support device for put-away and release is arranged in a position, corresponding to the square hole, inside the bending part. The automatic support device for put-away and release comprises a direction guide groove frame connected on the back side of an inside support, a baffle arranged under the direction guide groove frame and an idler wheel connected with the baffle through a connecting frame. According to the dust collector provided with the automatic support device for put-away and release, when the upward inclined angle of the front end of a machine body is larger than 30 degrees, the idler wheel extends out of the square hole of the bottom shell to be used as a new supporting wheel and rolls forward. Thus, when the dust collector moves forward, parts such as the bottom shell and an exhaust cover of the machine body can not damage the machine body due to friction with the ground. When the machine body is placed horizontally, the idler wheel retracts into the square hole and is put away. Consequently, the appearance and normal utilization of the dust collector can not be influenced.
Description
technical field [0001] The invention belongs to a structure of a vacuum cleaner, in particular to a vacuum cleaner with an automatic retractable support device which is arranged at the rear end of the bottom shell of the vacuum cleaner and plays a supporting role when the body is tilted to prevent the body from rubbing against the ground. Background technique [0002] Vacuum cleaner is a cleaning and sanitary electrical device used to remove dust from floors, carpets, walls, furniture, clothing and various gaps. Generally speaking, a vacuum cleaner mainly includes a suction device and a suction pipeline. The suction device mainly formed by a motor and a fan is arranged in the body. The suction pipeline includes a suction head and a suction pipe. The air port communicates with the air inlet of the fan inside the body through the telescopic pipe and flexible pipe of the suction pipe. [0003] When the vacuum cleaner is running, the motor drives the impeller of the fan to rota...
