Description

[Detailed explanation of the idea] This invention relates to a vacuum cleaner.

Conventionally, in this type of filter, dust removal from the filter is often performed before or after cleaning, and requires some kind of operation.

Further, in the case of a device that automatically performs the operation using vibration or the like during use, there is a problem that the driving force is too strong, causing fine dust to pass through the filter.

The purpose of this invention is to provide a vacuum cleaner that can automatically remove dust with appropriate dust removal energy during cleaning, and that can always clean with good suction.

This device forms a spindle-shaped main body to which a suction port is connected at one end, and forms multiple grooves with different inclination directions on the front and back on the outer peripheral surface of this main body. In addition, a plurality of rollers are rotatably attached with some of them protruding from the outer periphery.

Therefore, when cleaning by pulling the suction port body, the main body swings, and the vibration of the main body at this time, the movement of the dust captured by the filter, and the interference between the dust particles can be used to constantly remove dust from the filter. The structure is such that cleaning can be performed with good suction.

An embodiment of this invention will be described based on the drawings.

Reference numeral 1 denotes a spindle-shaped main body with a circular cross section, and the outer diameter decreases from the center toward both ends.

The main body 1 includes an electric case 2 that houses an electric blower (not shown) therein, and a dust collection case 3 that is detachably connected to the open end of the electric case 2.

A suction port 4 is formed at the front end of the dust collecting case 3, and a suction port body 5 is detachably connected to the suction port 4.

Further, a filter 7 is provided in the dust collection chamber 6 of the dust collection case 3.

A plurality of grooves 8 are formed on the outer periphery of the main body 1, the directions of inclination being different at the front and back of the main body 1.

That is, the direction of inclination of the grooves 8 is symmetrical in the electric case 2 and the dust collection case 3, and the direction of inclination of the adjacent grooves 8 is also alternated.

A plurality of rollers 9 serving as guide portions are attached to such a groove 8 so as to be rotatable in a direction along the longitudinal direction of the groove 8, with a portion of the rollers 9 protruding from the outer periphery.

In such a configuration, cleaning is performed while pulling the suction port body 5, but since the roller 9 is provided at an angle with the longitudinal direction of the main body 1, the main body 1 is able to move the roller 9 that is in contact with the floor surface. Rotates in one direction depending on the direction of inclination.

The main body 1 is pulled intermittently, and the main body 1 is rotated by being returned to the direction opposite to the direction in which it rotated when stopped.

That is, it rotates in one direction due to tension, which twists the flexible hose, and when it is stopped, the twist is restored, and the hose is rotated in the opposite direction and restored.

Therefore, vibration is applied to the filter 7, and the dust captured by the filter moves and the dust interferes with itself.
As a result, the dust clogging the filter 7 falls into the dust collection chamber 6.

Furthermore, as another form of movement, the front part may be pulled up momentarily by the suction port body 5, and in such a case, the main body 1 becomes pitched because the outer diameter of the main body 1 becomes narrower from the center toward both ends. Move while doing so.

That is, the rotation direction of the main body 1 changes every time the roller 9 on the dust collection case 3 side comes into contact with the floor surface, or the roller 9 on the electric case 2 side comes into contact with the floor surface, and the direction of inclination of the groove 8 changes.

Furthermore, even when the rollers 9 of either case 2 or 3 are in contact with the floor, when the rollers 9 of the other grooves 8 are in contact with the floor due to the rotation of the main body 1, the inclination directions of the grooves 8 are alternately changed. Since the rotation direction of the main body 1 is changed, the direction of rotation of the main body 1 is reversed.

The shock at this time is transmitted to the filter 7 and the dust captured by the filter, and the dust can be removed effectively.

This idea is based on the fact that, as mentioned above, grooves are formed on the outer periphery of the main body with different directions of inclination at the front and back, and a roller is rotatably attached along these grooves, so that when the suction port is pulled, the main body moves to the right. Alternatively, it can be rotated to the left, and the vibration transmitted to the filter at this time and the movement and interference of the dust captured by the filter can be used to remove dust while cleaning.
This allows cleaning to be performed with good suction at all times.
