AI Technical Summary
The existing roller brushes cannot deform and provide buffering due to the inability to deform the hard roller body, resulting in large-sized solid dirt that cannot be sucked in when cleaning uneven surfaces. The instantaneous current of the motor increases, which affects the equipment life and cleaning effect, and is not effective in cleaning surfaces with high humidity.
The buffer rubber sleeve and elastic scraper are designed. The buffer rubber sleeve is equipped with reinforced rib rings and dispersed through holes. It is combined with the elastic scraper and cleaning brush plate to achieve push and inhalation of large-sized solid dirt. When the buffer rubber sleeve deforms, the gas is evenly dispersed to ensure the stability of the equipment.
It can effectively clean the dry and humidity surfaces to be cleaned, and large-sized solid dirt can pass smoothly, avoid motor overload, extend equipment life and improve cleaning effect.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cleaning equipment, in particular to a roller brush cleaning mechanism. Background Technique
[0002] At present, household or industrial cleaning equipment mainly includes a main body and a floor brush assembly. Among them, the most important functional component in the floor brush assembly is the roller brush assembly. The contact surface and frictional force between the roller brush in the roller brush assembly and the surface to be cleaned will directly affect the service life, cleaning effect and cleaning experience of the equipment.
[0003] At present, existing roller brushes are all hard roller bodies wrapped with a layer of cleaning flannelette. Since the roller body itself cannot deform to provide buffering, and the cleaning flannelette only plays a role in surface wiping, when cleaning an uneven surface to be cleaned, due to the interference with the hard roller brush and the too small gap between the roller body and the surface to be cleaned, large-size solid dirt in front of the cleaning equipment cannot be sucked into the gap, or even if it is sucked in, it will cause an instantaneous increase in the current of the motor, affecting the service life of the motor and the cleaning effect. In addition, the cleaning flannelette has a good cleaning effect on a dry surface to be cleaned, but has a poor cleaning effect on a relatively humid surface to be cleaned. Therefore, we propose a roller brush cleaning mechanism. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a roller brush cleaning mechanism, which has the advantages of good cleaning effect and can easily clean large-size solid dirt, and solves the problem that existing roller brushes are all hard roller bodies wrapped with a layer of cleaning flannelette. Since the roller body itself cannot deform to provide buffering, and the cleaning flannelette only plays a role in surface wiping, when cleaning an uneven surface to be cleaned, due to the interference with the hard roller brush and the too small gap between the roller body and the surface to be cleaned, large-size solid dirt in front of the cleaning equipment cannot be sucked into the gap, or even if it is sucked in, it will cause an instantaneous increase in the current of the motor, affecting the service life of the motor and the cleaning effect. In addition, the cleaning flannelette has a good cleaning effect on a dry surface to be cleaned, but has a poor cleaning effect on a relatively humid surface to be cleaned.
[0005] To achieve the above object, the utility model provides the following technical solution: A roller brush cleaning mechanism, comprising:
[0006] A buffer rubber sleeve bonded to the outer surface of the roller brush cylinder. A plurality of equally spaced reinforcing rib rings are arranged in the inner cavity of the buffer rubber sleeve. A plurality of equally angularly distributed dispersion through holes are formed on the inner surface of the reinforcing rib ring. The buffer rubber sleeve forms a plurality of equally spaced cavities in its inner cavity through the reinforcing rib rings;
[0007] An elastic scraper, which is equally angularly arranged on the outer surface of the buffer rubber sleeve;
[0008] The cleaning brush plate is arranged on the outer surface of the buffer rubber sleeve at equal angles.
[0009] Preferably, the roller brush cylinder is a hollow cylindrical structure.
[0010] Preferably, the material of the buffer rubber sleeve is wear-resistant rubber.
[0011] Preferably, the longitudinal section of the elastic scraper is an isosceles triangle, and the number of elastic scrapers is multiple.
[0012] Preferably, the number of the cleaning brush plates is the same as that of the elastic scrapers, and the cleaning brush plates are located at the middle positions between two adjacent elastic scrapers.
[0013] Preferably, the material of the elastic scraper is elastic rubber.
[0014] Preferably, connecting components are arranged at both the left and right ends of the inner cavity of the roller brush cylinder. A connecting shaft is arranged at the middle end of the connecting component, and a belt pulley is fixedly installed at one end of the connecting shaft away from the connecting component.
[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0016] 1. Through the arrangement of the cleaning brush plate, the present utility model can effectively clean the dry surface to be cleaned, and with the assistance of the elastic scraper, the cleaning effect of the dry surface to be cleaned is ensured. The arrangement of the elastic scraper can scrape the dirt on the relatively humid surface to be cleaned when the cleaning brush plate fails to completely clean the dirt on the relatively humid surface to be cleaned, ensuring the cleaning effect of the surface to be cleaned.
[0017] 2. When encountering solid dirt with a relatively large size during the cleaning process, the cleaning brush plate and the elastic scraper can complete the pushing work of the solid dirt. When it passes below this mechanism, the buffer rubber sleeve can deform at the corresponding position with the assistance of the cavity and the reinforcing rib ring. When the buffer rubber sleeve deforms, the gas in the corresponding cavity can be evenly dispersed in the buffer rubber sleeve through the dispersion through holes, so as to ensure the stability of the external shape of the buffer rubber sleeve except for the deformed area, and then enable the solid dirt with a relatively large size to pass through smoothly and be sucked into the cleaning device.

[0027] Embodiment 1
[0028] Please refer toFigures 1-4 As shown in the figure, the present utility model provides a technical solution: a roller brush cleaning mechanism, including: a buffer rubber sleeve 4 adhered to the outer surface of the roller brush cylinder 1, an elastic scraper 7, and a cleaning brush plate 5;
[0029] The roller brush cylinder 1 is a hollow cylindrical structure. The material of the buffer rubber sleeve 4 is wear-resistant rubber. A plurality of equally spaced reinforcing rib rings 9 are arranged in the inner cavity of the buffer rubber sleeve 4. A plurality of equally angled distributed dispersion through holes 8 are provided on the inner surface of the reinforcing rib ring 9. The buffer rubber sleeve 4 forms a plurality of equally spaced cavities 6 in its inner cavity through the reinforcing rib rings 9. The longitudinal section of the elastic scraper 7 is an isosceles triangle, and the number of the elastic scrapers 7 is multiple. The material of the elastic scraper 7 is elastic rubber. The elastic scrapers 7 are arranged at equal angles on the outer surface of the buffer rubber sleeve 4. The number of the cleaning brush plates 5 is the same as that of the elastic scrapers 7, and the cleaning brush plates 5 are located at the middle positions between adjacent two elastic scrapers 7. The cleaning brush plates 5 are arranged at equal angles on the outer surface of the buffer rubber sleeve 4.
[0030] In this technical solution: through the setting of the cleaning brush plate 5, effective cleaning work can be carried out on the dry surface to be cleaned, and with the assistance of the elastic scraper 7, the cleaning effect of the dry surface to be cleaned is guaranteed. And the setting of the elastic scraper 7 can scrape the dirt on the surface to be cleaned with relatively high humidity when the cleaning brush plate 5 fails to thoroughly clean the dirt on the surface to be cleaned with relatively high humidity, guaranteeing the cleaning effect of the surface to be cleaned. When encountering solid dirt with a relatively large size during the cleaning process, the cleaning brush plate 5 and the elastic scraper 7 can complete the pushing work of the solid dirt. When it passes below this mechanism, the buffer rubber sleeve 4 can deform at the corresponding position with the assistance of the cavity 6 and the reinforcing rib ring 9. When the buffer rubber sleeve 4 deforms, the gas in the corresponding cavity 6 can be evenly dispersed in the buffer rubber sleeve 4 through the dispersion through holes 8, thus guaranteeing the stability of the external shape of the buffer rubber sleeve 4 except for the deformed area, and further enabling the solid dirt with a relatively large size to pass through smoothly and be sucked into the cleaning device (it should be noted that this mechanism is installed on the cleaning device for work before use and does not operate independently).
[0031] Embodiment 2
[0032] On the basis of Embodiment 1, as shown in the present utility model Figure 1 and Figure 3 as well as Figure 4 it is disclosed that connecting components 2 are arranged at both the left and right ends of the inner cavity of the roller brush cylinder 1. A connecting shaft 10 is arranged in the middle of the connecting component 2. A belt pulley 3 is fixedly installed at one end of the connecting shaft 10 far away from the connecting component 2.
[0033] Technical solution: Through the provision of two connecting components 2, a connecting shaft 10, and a pulley 3, it is possible to avoid the situation where one end of the roller brush cylinder 1 is forced to drive the mechanism to work, resulting in a phenomenon of one end being heavy and the other end being light during operation, and the uneven force at both ends. This ensures the stability of the overall structure of the mechanism.
