Abstract

The utility model provides a cleaning head device, includes casing (1) and locates the brush head in casing (1), its characterized in that the bottom opening of casing (1) forms and cleans the port, the brush head include dwang (2), locate support (3) of dwang (2) lower extreme and locate brush hair (33) of terminal surface under support (3), have elasticity and can stretch out and draw back in the aforementioned support (3) direction of height. Through the scalable design of support self-adaptation, increased the effort of brush hair with the working surface, the brush head after flexible reduces occupation space, does benefit to and cleans efficiency in providing.

Description

Cleaning head device

Technical Field

The invention relates to an object surface cleaning device, in particular to a cleaning head structure applied to a dust collector.

Background

In the suction head of the vacuum cleaner in the prior art, a rotor is driven by a motor to drive a rolling brush, and the rolling brush is positioned in a shell. The dust collector has the advantages that the dust is swept up through the action of the bristles on the rolling brush and the working surface, and finally sucked into the dust collector through the negative pressure of the suction head, the bristles are fixed with the acting force of the working surface due to the fixation of the rolling brush at present, so that the adjustment of the acting force of the bristles and the working surface is limited, the working surface with certain fluctuation cannot be thoroughly cleaned, the capacity of cleaning stubborn stains is insufficient, and the degree of cleaning the dust is limited to a certain extent.

Disclosure of Invention

The invention aims to solve the technical problem of providing a cleaning head device which can automatically adjust the action force of bristles and a working surface in view of the technical current situation.

The technical scheme adopted by the invention for solving the technical problems is as follows: the utility model provides a cleaning head device, includes the casing and locates the brush head in the casing, its characterized in that the bottom opening of casing forms and cleans the port, the brush head include the dwang, locate the support of dwang lower extreme and locate the brush hair of terminal surface under the support, have elasticity and can stretch out and draw back in the aforementioned support direction of height.

Preferably, the support is in a spiral shape from inside to outside and comprises an inner ring and an outer ring, the lower end of the rotating rod is connected with the inner ring and can drive the inner ring to rotate, and the bristles are arranged on the lower end faces of the outer ring and the inner ring. The spiral bracket is similar to a tower spring, the design is simple, and the expansion can be automatically adjusted.

And the inner wall of the lower end of the shell is provided with a spiral guide groove which is in guide fit with the outer ring of the bracket. The stability of the support can be ensured and the force on the working surface can be maintained at a certain level.

Preferably, the housing includes an upper tapered portion and a lower cylindrical portion, and the spiral guide groove is formed on an inner wall of the cylindrical portion.

The upper end of the rotating rod extends out of the shell to form a power input end. The power of the rotating rod can be driven by other driving mechanisms.

Compared with the prior art, the invention has the advantages that: through the scalable design of support self-adaptation, increased the effort of brush hair and working surface and the working surface of brush hair, provide sufficient power of cleaning to the working surface of stubborn spot, can adapt to various uneven working surfaces, also strengthen the cleaning ability of brush head on the whole, brush head after flexible reduces occupation space, does benefit to and cleans efficiency in providing.

Detailed Description

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

As shown in fig. 1, 2 and 3, the cleaning head device in this embodiment includes a housing 1 and a brush head disposed in the housing 1, the housing 1 includes an upper conical portion 11 and a lower cylindrical portion 12, and a spiral guide groove 13 is formed on an inner wall of the cylindrical portion 12. The bottom end of the cylindrical portion 12 is open to form a cleaning port.

The brush head comprises a rotating rod 2, a support 3 arranged at the lower end of the rotating rod 2 and bristles 33 arranged on the lower end face of the support 3, and the support 3 has elasticity in the height direction and can stretch. The upper end of the swivelling levers 2 extends out of the housing 1 to form the power input.

Specifically, the support 3 is in a spiral shape from inside to outside, similar to a tower-shaped spring, and comprises an inner ring 32 and an outer ring 31, the lower end of the rotating rod 2 is connected with the inner ring 32 and can drive the inner ring 32 to rotate, and the bristles 33 are arranged on the lower end faces of the outer ring 31 and the inner ring 32. The outer ring 31 is in guiding engagement with the helical guide groove 13.

When the cleaning acting force is strengthened, the bracket 3 is contracted, the cleaning bristles 33 are increased, when the cleaning acting force is not strengthened, the bracket 3 is extended, and only the bristles 33 at the outer ring work to clean.

The embodiment is used as a part of the dust collector and mainly bears the cleaning work, and the dust collection work of the cleaning is completed by other mechanisms.
