Technical Field

[0001] The utility model relates to the technical field of floor scrubbers, in particular to a cleaning and disinfecting device used on a roller brush of a floor scrubber. Background Art

[0002] A floor scrubber, also known as a floor washing car or a floor cleaning machine, is a cleaning machine suitable for cleaning hard floors. It also has the function of sucking up sewage and taking it away from the site. It has the advantages of environmental protection, energy saving, and high efficiency.

[0003] The roller brush of a floor scrubber is the main cleaning component of the floor scrubber. It usually cleans the floor by rotating the roller brush. A pipe connected to a clean water tank is provided on the roller brush. Water is sprayed onto the floor while the roller brush rotates, so that the roller brush drives the water to flush the floor while rolling, thereby achieving the purpose of cleaning.

[0004] The roller brushes used in the floor scrubbers currently on the market need to be replaced or disassembled for cleaning after being used for a period of time. If they are not replaced or cleaned, bacteria will remain on the roller brush, which will easily cause mold and stink and breed more bacteria, resulting in subsequent cleaning failures. The replacement or cleaning process needs to be done by people themselves, which is time-consuming and labor-intensive, causing inconvenience to users. Utility Model Content

A UV lamp is arranged in the head of the floor scrubber to disinfect the roller brush, so as to prevent the roller brush of the floor scrubber from getting moldy and smelly and ensure the service life of the roller brush of the floor scrubber. With a flat mirror, the light of the UV lamp can be directly irradiated onto the roller brush. With a convex lens, the light of the UV lamp can be concentrated and irradiated onto the roller brush to improve the sterilization intensity. With a concave lens, the light of the UV lamp can be diffused and irradiated onto the roller brush to improve the uniformity of sterilization. Different schemes are provided for people to choose from, which further improves the scope of application and practicality of the device.

[0012] As a further improvement of the utility model, one end of the avoidance penetration portion opposite to the light limiting groove is a transparent flat mirror, and the light emitted by the UV ultraviolet disinfection lamp passes through the flat mirror and directly shines on the roller brush.

[0013] As a further improvement of the utility model, the end of the avoidance penetration portion opposite to the light limiting groove is a transparent convex lens, and the light emitted by the UV ultraviolet disinfection lamp passes through the convex lens to be concentrated and irradiated on the roller brush.

[0014] As a further improvement of the utility model, the end of the avoidance penetration portion opposite to the light limiting groove is a transparent concave lens, and the light emitted by the UV ultraviolet disinfection lamp passes through the concave lens and is dispersedly irradiated on the roller brush.

[0015] As a further improvement of the present invention, the number of the UV ultraviolet disinfection lamps is 8 groups, which are evenly arranged in sequence on the PCB board.

[0016] The beneficial effects of the utility model are:

[0017] By configuring the device to include a machine head, a roller brush disposed on the machine head, a transparent member disposed in the machine head and half-wrapped on the roller brush, and at least one UV ultraviolet disinfection lamp disposed on the transparent member directly opposite the roller brush, the light emitted by the UV ultraviolet disinfection lamp passes through the transparent member and irradiates the roller brush, thereby cleaning and disinfecting the roller brush, preventing the roller brush of the floor scrubber from getting moldy and smelly, and ensuring the service life of the roller brush of the floor scrubber.

[0040] Embodiment 1

[0041] Please refer to Figures 1 to 8 The present invention provides a cleaning and disinfecting device for a roller brush 2 of a floor scrubber, comprising a machine head 1, a roller brush 2 arranged on the machine head 1, and is characterized in that it also comprises a transparent member 3 arranged in the machine head 1 and half-wrapped on the roller brush 2, and at least one UV ultraviolet disinfection lamp 4 arranged on the transparent member 3 facing the roller brush 2, and the light emitted by the UV ultraviolet disinfection lamp 4 passes through the transparent member 3 and irradiates the roller brush 2.

[0042] By configuring the device to include a machine head 1, a roller brush 2 arranged on the machine head 1, a transparent member 3 arranged in the machine head 1 and half wrapped on the roller brush 2, and at least one UV ultraviolet disinfection lamp 4 arranged on the transparent member 3 and facing the roller brush 2, the light emitted by the UV ultraviolet disinfection lamp 4 passes through the transparent member 3 and irradiates the roller brush 2, thereby cleaning and disinfecting the roller brush 2, preventing the roller brush 2 of the floor scrubber from getting moldy and smelly, and ensuring the service life of the roller brush 2 of the floor scrubber. By arranging a transparent member 3 in the machine head 1, while fixing the UV ultraviolet disinfection lamp 4, the structure made of transparent material can also allow the light emitted by the UV ultraviolet disinfection lamp 4 to penetrate, preventing the roller brush 2 from directly rubbing against the UV ultraviolet disinfection lamp 4 and ensuring the cleaning effect of the UV ultraviolet disinfection lamp 4 on the roller brush 2.

[0043] The UV disinfection lamp 4 is a conventional part in the industry, and its control method and structure are conventional technical means in the industry, so they are not described in detail in this embodiment.

[0044] Regarding the specific manner in which the UV ultraviolet disinfection lamp 4 is arranged on the transparent member 3, as shown in FIG. Figures 1 to 4 As shown, the device also includes a PCB board 5 arranged on the transparent part 3, the UV ultraviolet disinfection lamp 4 is arranged on the PCB board 5 and electrically connected to the PCB board 5, and the PCB board 5 is electrically connected to the control module in the floor scrubber, so that the UV ultraviolet disinfection lamp 4 is controlled by the control module of the floor scrubber to start and shut down, and different modes of cooperation with other components can be determined according to the program in the control module, thereby adding different schemes for people to choose from and improving the practicality of the floor scrubber.

[0045] Preferably, Figure 4 As shown, the PCB board 5 may also be provided with a separate switch for separately controlling the UV disinfection lamp 4, which is convenient for maintenance, and the PCB board 5 may also be provided with a resistor corresponding to the UV disinfection lamp 4, which is convenient for coordination between the various components.

[0046] The specific method of arranging the PCB board 5 and the UV disinfection lamp 4 on the transparent member 3 is as follows: Figures 6 to 8As shown, the side of the transparent member 3 close to the roller brush 2 is formed with an avoidance penetration portion 31 which is semi-arc-shaped and matches the shape of the roller brush 2. The upper end of the transparent member 3 is formed with an insertion cavity 32. A PCB stop plate 33 protrudes from the middle of the insertion cavity 32. A light stop groove 34 for inserting the UV ultraviolet disinfection lamp 4 is formed between the PCB stop plate 33 and the inner wall of the insertion cavity 32 facing the roller brush 2. The PCB board 5 is fixed above the light stop groove 34 and pressed against the PCB stop plate 33. The UV ultraviolet disinfection lamp 4 is inserted into the light stop groove 34, thereby achieving the fixing effect on the PCB board 5 and the UV ultraviolet disinfection lamp 4, and preventing the PCB board 5 and the UV ultraviolet disinfection lamp 4 from shifting during operation. By setting the avoidance penetration portion 31 to be semi-arc-shaped, so as to match the shape of the roller brush 2, the roller brush 2 will not hinder the normal operation of the roller brush 2 when cleaning the ground, which is conducive to the coordination of various components.

[0047] In order to further strengthen the position of the PCB board 5 and the UV disinfection lamp 4, as shown in FIG. Figure 3 and Figure 5 as well as Figure 8 As shown, at least one reinforcing plate 35 connected to the PCB limiting plate 33 is formed on the side of the insertion cavity 32 away from the roller brush 2. Preferably, the number of the reinforcing plates 35 is 3 groups, which are arranged in sequence and connected to the PCB limiting plate 33, so that the PCB limiting plate 33 is fixed to the inner wall of the insertion cavity 32 away from the roller brush 2, preventing the problem of the PCB limiting plate 33 breaking in the process of carrying the PCB board 5, improving the practicality of the device, and facilitating the coordination between the various components. And the outermost end of the reinforcing plate 35 is pressed against the PCB board 5, so as to further fix the position of the PCB board 5, preventing the PCB board 5 from shifting during operation, causing the UV ultraviolet disinfection lamp 4 to be unable to be used normally, and further improving the accuracy of the UV ultraviolet disinfection lamp 4 in cleaning and disinfecting the roller brush 2.

[0048] The specific method of fixing the PCB board 5 on the light limiting groove 34 is as follows: Figure 5As shown, a first PCB fixing hole 36 extending toward the inner wall of the insertion cavity 32 near the roller brush 2 is formed on the inner wall of the insertion cavity 32 near the roller brush 2, and a second PCB fixing hole 37 extending toward the PCB limiting plate 33 and symmetrical to the first PCB fixing hole 36 is formed on the inner wall of the insertion cavity 32 near the roller brush 2. One side of the PCB board 5 is screwed through itself and locked in the first PCB fixing hole 36, and the other side of the PCB board 5 is screwed through itself and locked in the second PCB fixing hole 37, so that the PCB board 5 is fixed on the light limiting groove 34, and then the UV ultraviolet disinfection lamp 4 set on the PCB board 5 is fixed in the light limiting groove 34 and facing the roller brush 2, thereby improving the accuracy of the UV ultraviolet disinfection lamp 4 in cleaning and disinfecting the roller brush 2. The symmetrical arrangement of the first PCB fixing hole 36 and the second PCB fixing hole 37 makes the fixing force of the PCB board 5 uniform and improves the firmness of the fixing of the PCB board 5. By setting the second PCB fixing hole 37 on the inner wall extension of the insertion cavity 32 close to the roller brush 2, and setting the first PCB fixing hole 36 on the inner wall extension of the PCB limiting plate 33, the two are respectively connected to different structures to further disperse the bearing force of the PCB board 5, thereby preventing the problem of concentrated bearing force and side wall breakage caused by single fixation on the PCB limiting plate 33 or the insertion cavity 32.

[0049] Regarding the specific method of the UV ultraviolet disinfection lamp 4 passing through the transparent member 3, as shown in FIG. Figure 8 As shown, the end of the avoidance penetration portion 31 opposite to the light limiting groove 34 is a transparent flat mirror, and the light emitted by the UV ultraviolet disinfection lamp 4 passes through the flat mirror and directly shines on the roller brush 2, thereby achieving the purpose of cleaning and disinfecting the roller brush 2 by the UV ultraviolet disinfection lamp 4.

[0050] The flat mirror can be integrally formed with the transparent member, or can be clamped separately. It can be adjusted and selected according to actual conditions, so no specific limitation is made in this embodiment.

[0051] Preferably, Figure 7 As shown, a labyrinth-shaped guide surface 38 may be further provided on the back of the transparent member 3, and a plurality of guide holes 39 matching the guide surface 38 may be further provided on the lower end of the transparent member 3. Clean water is fed into the guide surface 38 from the outside and guided by the guide surface 38, thereby being evenly distributed on the lower part of the transparent member 3, and then sprayed onto the roller brush 2 through the guide holes 39 at the lower part of the transparent member 3, so that the roller brush 2 is moistened to clean the ground.

[0052] Preferably, Figure 3 to Figure 4As shown, the number of the UV ultraviolet disinfection lamps 4 is 8 groups, which are evenly arranged in sequence on the PCB board 5, so as to evenly clean and disinfect the roller brush 2 below, improve the cleaning and disinfection ability of the device, prevent the roller brush 2 of the floor scrubber from mold and odor, and ensure the service life of the roller brush 2 of the floor scrubber.

[0053] Embodiment 2

[0054] In the first embodiment, the structure of the cleaning and disinfecting device is described. In this embodiment, the differences from other embodiments are mainly described, and the same structure is not repeated in this embodiment.

[0055] like Figures 9 and 10 As shown, the main difference between Example 2 and Example 1 is that the avoidance penetration portion 31 in this embodiment is a transparent convex lens at one end opposite to the light limiting groove 34, and the light emitted by the UV ultraviolet disinfection lamp 4 passes through the convex lens and is concentrated on the roller brush 2. Specifically, the parallel light emitted by the UV ultraviolet disinfection lamp 4 is incident on the convex lens, and after being refracted in the convex lens, the light is concentrated at a point on the axis of the convex lens, thereby realizing the focusing function, improving the sterilization ability of the UV ultraviolet disinfection lamp 4 on the roller brush 2, further preventing the roller brush 2 from moldy and smelly, and ensuring the service life of the roller brush 2 of the floor scrubber.

[0056] The convex lens can be integrally formed with the transparent member, or can be clamped separately. It can be adjusted and selected according to actual conditions, so no specific limitation is made in this embodiment.

[0057] Embodiment 3

[0058] In the first embodiment, the structure of the cleaning and disinfecting device is described. In this embodiment, the differences from other embodiments are mainly described, and the same structure is not repeated in this embodiment.

[0059] like Figure 11 to Figure 12 As shown, the main difference between Example 3 and Example 1 and Example 2 is that the avoidance penetration portion 31 in this embodiment is a transparent concave lens at one end opposite to the light limiting groove 34, and the light emitted by the UV ultraviolet disinfection lamp 4 passes through the concave lens and is dispersedly irradiated on the roller brush 2. Specifically, the parallel light emitted by the UV ultraviolet disinfection lamp 4 is incident on the concave lens, refracted by the concave lens and diverged in all directions, so that the light emitted by the UV ultraviolet disinfection lamp 4 can be evenly irradiated to different positions of the roller brush 2, thereby improving the uniformity of sterilization, further preventing the roller brush 2 from moldy and smelly, and ensuring the service life of the roller brush 2 of the floor scrubber.

[0060] The concave lens can be integrally formed with the transparent member, or can be clamped separately. It can be adjusted and selected according to actual conditions, so no specific limitation is made in this embodiment.

[0061] It should be noted that the cleaning and disinfection device for the roller brush of the floor scrubber disclosed in the utility model is an improvement on the specific structure, and the specific control method is not the innovation point of the utility model. The UV ultraviolet disinfection lamp, screws, roller brush, concave lens, convex lens, flat mirror and other components involved in the utility model can be universal standard parts or components known to those skilled in the art, and their structures, principles and control methods are all known to those skilled in the art through technical manuals or conventional experimental methods.
