Detailed Description

The utility model is described in further detail below with reference to the accompanying examples.

As shown in fig. 1, the power-assisted vacuum cleaner in this embodiment includes a housing 1, a traveling wheel 2 rotatably connected to two sides of the housing 1, a detection component 3 disposed in the housing 1 and capable of detecting a traveling trend direction of the traveling wheel 2, a power-assisted mechanism 4 disposed in the housing 1 and in driving connection with the traveling wheel 2, and a control circuit board electrically connected to the detection component 3 and the power-assisted mechanism 4. Wherein the control circuit board determines the installation position of the dust collector according to the specific installation space of the dust collector.

As shown in fig. 3, the detection unit 3 includes a hollow tube 31 disposed along the traveling direction, a ball 32 disposed in the hollow tube 31, and contact switches 33 disposed at both ends of the hollow tube 31, and each of the contact switches 33 is electrically connected to the control circuit board. In this embodiment, the ball 32 is a steel ball, and the diameter of the ball 32 is only slightly smaller than the diameter of the hollow tube 31, so that the ball 32 can roll back and forth in the hollow tube 31 to touch the contact switch 33. The traveling direction of the cleaner is generally the front-rear direction, and the hollow pipe 31 is disposed in the housing 1 in the front-rear direction. When the vacuum cleaner is moving forward, based on the inertia of the housing 1, the ball 32 will roll backward in the hollow tube 31, and then touch the contact switch 33 located behind the hollow tube 31 when reaching the rear end of the hollow tube 31, and the contact switch 33 located behind the hollow tube 31 is a detector for detecting the forward movement of the vacuum cleaner. When the cleaner travels backward, the ball 32 rolls forward in the hollow tube 31 based on the traveling inertia of the housing 1, and then touches the contact switch 33 located in front of the hollow tube 31 when reaching the front end of the hollow tube 31, and the contact switch 33 provided in front of the hollow tube 31 is a detector for detecting the backward travel of the cleaner.

In order to make the ball 32 conveniently reset when the vacuum cleaner is not in a walking state, the middle part of the inner bottom surface of the hollow tube 31 is inclined and recessed relative to the two ends, and in order to better realize the positioning of the ball 32 at the recessed position and avoid the ball 32 from swinging back and forth in the hollow tube 31, the middle part of the inner bottom surface of the hollow tube 31 is provided with a positioning hole 311 with the aperture smaller than the diameter of the ball 32.

In addition, in order to ensure the stability of the ball 32 touching the contact switch 33 when the ball 32 reaches the end of the hollow tube 31, the two ends of the inner bottom surface of the hollow tube 31 are respectively provided with a limit hole 312 with a diameter smaller than the diameter of the ball 32, and the setting position of the limit hole 312 satisfies the following conditions: after the ball 32 is limited in the limiting hole 312, the ball 32 can touch the contact switch 33. The hollow tube 31 is closed at both ends, a small hole 313 is opened on the end face of the hollow tube 31, and the contact part of the contact switch 33 is fittingly inserted into the small hole 313.

As shown in fig. 2, the power assisting mechanism 4 comprises a motor and a transmission component connected to the driving end of the motor, the motor is in electric signal connection with the control circuit board, and the transmission component is in transmission connection with the traveling wheel 2.

In order to facilitate the estimation of the movement of the power-assisted dust collector, a handle is connected to the housing 1, after the power-assisted dust collector is started, a user holds the handle to push the dust collector to walk, the control circuit board detects and acquires the trigger signals of the two contact switches 33 in real time, and then the walking direction of the current power-assisted dust collector is judged according to the trigger signals of the two contact switches 33. Then the control circuit board controls the rotation direction of the motor in the power-assisted mechanism 4 according to the judged walking direction information, so that the power-assisted mechanism 4 provides power assistance in the current walking direction for the walking wheels 2.

When the vacuum cleaner is at rest, the ball 32 is reset to the positioning hole 311 based on the inclined concave structure at the bottom of the hollow tube 31, and at this time, the ball 32 will not contact any contact switch 33, and the power assisting mechanism 4 will not operate.

When the dust collector is in a non-starting state, the power assisting mechanism 4 does not work no matter whether the ball body 32 touches the punishment switch or not, and the use safety is ensured.

The dust collector in the embodiment can be an ordinary dust collector and can also be a suction and mopping integrated machine, particularly, for the dust collector which needs to use a brush or a rubber strip and has a large friction force with the ground, the power assisting effect in the use process is more obvious, and a user can use the dust collector more time-saving and labor-saving.
