Abstract
The utility model discloses a roller brush for a vacuum cleaner, which comprises a roller and the brush mounted on the roller. The roller brush is driven by a transmission mechanism. The utility model is characterized in that both ends of the roller are provided with the brackets which are connected with an outer shell of a floor brush of the vacuum cleaner; the end parts of the roller are fixedly connected with the rolling balls; the ball cages matching with the rolling balls are mounted on the brackets, which produce the spherical surface fit rotation connection structure between the roller and the bracket. Both ends of the roller of the utility model are provided with a location axis, the rolling balls and the brackets, which produces a universal joint similar structure. The roller brush has certain vibration degree of freedom which reduces the dithering of the roller brush and decreases the direct acting force towards the outer shell at the same time. And the roller brush improves the vibration condition of the whole floor brush and reduces the noise.
Description
Technical field
The utility model relates to a kind of dust catcher accessory, is specifically related to a kind of dust catcher roller brush with vibrational degrees of freedom.
Background technology
In order to realize the multiple function of dust catcher, dust catcher can be equipped with a plurality of suction nozzles, and wherein a kind of is the scrubbing brush with roller type bristle.This scrubbing brush mainly by shell, be arranged at the bend pipe connector on the shell, the roller brush that is arranged in the shell constitutes, roller brush comprises that roller bearing and spiral are arranged at the bristle on the roller bearing, roller brush links to each other with transmission mechanism, and is rotationally connected by roller bearing and shell; Outer casing bottom has suction port, and suction port is connected with bend pipe by the dust absorption passage in the shell, and this roller brush is positioned at the suction port place.During dust catcher work, transmission mechanism drives roller bearing and rotates, and bristle also rotates along with roller bearing, rolls floor-dust and hair, makes it be inhaled into dust storage chamber by dust absorption passage.
Yet, in the prior art, roller bearing and shell in the scrubbing brush directly are rotationally connected, this structure has following shortcoming: (1) roller bearing is when rotating at a high speed, because the CONTACT WITH FRICTION on bristle and ground can cause roller bearing acutely to shake, and directly have influence on whole casing, cause scrubbing brush serious vibration when work, send noise, and influence the operate as normal of dust catcher; (2) because roller bearing contacts with the shell direct friction, easily cause the wearing and tearing of roller bearing, reduced the service life of scrubbing brush.
Summary of the invention
The utility model purpose provides a kind of dust catcher roller brush, by with the improvement of connection structure of outer shell, solve in the prior art problem of serious vibration in the scrubbing brush use.
For achieving the above object, the technical solution adopted in the utility model is: a kind of dust catcher roller brush, comprise roller bearing and the bristle that is arranged on the roller bearing, described roller brush is driven by transmission mechanism, be provided with the support that is connected with the floor brush of dust collector shell at the two ends of described roller bearing, the roller bearing end is fixedly connected with spin, and support is provided with the ball cage that cooperates with spin, makes to constitute the rotation connection structure that sphere cooperates between roller bearing and support.
In the technique scheme, for easy to process, described roller bearing can adopt the branch body structure, and making things convenient for the fixedly connected spin in two ends, promptly described roller bearing constitutes by the locating shaft at the axostylus axostyle of centre and two ends is fixedly connected.
Further technical scheme is provided with elastomer outside the described support, and support is connected with the groove buffering of floor brush of dust collector shell side bottom by described elastomer.Optimized technical scheme is to be provided with shell fragment in the bottom of described support, and to be supported on by shell fragment in the groove of floor brush of dust collector shell side bottom.
In the technique scheme, described bristle shape in the shape of a spiral distributes, and also can be other forms.
In the technique scheme, described transmission mechanism can be the mode of belt pulley transmission, also can be the kind of drive of rack-and-pinion, drives roller bearing by transmission mechanism and rotates, and roller brush is rolled thereupon; Transmission mechanism can be arranged on the end of roller bearing, also can be arranged on middle part or other positions of roller bearing.
In the technique scheme, described locating shaft and spin are metal, have certain rigidity.
Because the technique scheme utilization, the advantage that the utility model compared with prior art has is:
1. because the utility model is provided with locating shaft at the two ends of roller bearing, end at locating shaft is with spin, spin is arranged in the support again, form the structure of a similar universal joint, make roller brush except around the brush axle rotates, can also do to rotate by a small margin around support, eliminate the influence of vibration thus, the shake that has alleviated roller brush;
2. in the bottom of support shell fragment is set, and be supported on by shell fragment in the groove of two side bottom of shell, can also alleviate direct active force simultaneously so that whole roller brush has better vibrationproof performance in vertical direction, improve the vibration state of whole scrubbing brush shell;
3. because the employing of said structure by alleviating vibration, has been played the effect that reduces noise simultaneously.
