Power adjusting device for dust collector

Abstract

The invention discloses a power adjusting device for a dust collector, which is used for adjusting the power of the dust collector to meet the requirements of different occasions on suction. The power adjusting device consists of a knob, a knob bracket and a rheostat connected with the knob, wherein the power adjusting device is arranged on the side part of a dust collector body; and only a part of the knob is exposed outside the dust collector body. The power adjusting device can allow a user to optionally, conveniently and continuously change the power of the dust collector so as to meet the requirements of different places on the suction of the dust collector, and reduces a needed space, enhances touch effect, improves use convenience, simultaneously increases the rotation radius of the knob and enhances use safety.

Description

technical field [0001] The invention relates to a vacuum cleaner, in particular to an adjusting device for controlling the power of the vacuum cleaner. Background technique [0002] Generally, a vacuum cleaner is a device that uses a vacuum to generate suction to inhale air, make the air flow through various filters, filter foreign objects in the air, and clean the room. [0003] figure 1 It is a perspective view of a prior art vacuum cleaner. Such as figure 1 As shown, it includes: a fuselage 100 ; a suction pipeline connected to the suction side of the fuselage 100 . A fan and a dust collection unit 400 are provided inside the body 100 to send clean air to the outside after filtering out foreign objects in the air. [0004] The suction line is a line for sucking in air and foreign matter using the suction force of the body 100 . Specifically, the suction pipeline includes: a suction nozzle 1 that uses a strong air flow to inhale air containing foreign matter from the ...

Problems solved by technology

[0011] However, this kind of knob is completely exposed, and it is easy to be pulled out due to careless touch. At this time, the circuit board on the knob shaft will be exposed. Because the circuit board is of high voltage, it will endanger the safety of the operator in case of electric leakage.

[0012] Moreover, in the specific operation, when changing the power of the vacuum cleaner, the customer needs to bend down and operate by hand, which causes inconvenience to the user.

[0013] In addition, the exposed knob plate will wear out the power indicator characters during use, and it is difficult for users to determine the current power level during use.
