The scope of the present invention is defined by the appended claims.
Example one
The embodiment aims at solving the problem of bacterial breeding of the rolling brush assembly in the prior art to provide the sterilizing device capable of effectively sterilizing the rolling brush assembly.
The present embodiment provides a sterilization apparatus, which may be a separately installed sterilization apparatus for sterilizing a roll brush assembly detached from a cleaning device, or may be configured in the cleaning device for sterilizing the roll brush assembly of the cleaning device. Wherein, the cleaning equipment can be a cleaning machine with a rolling brush, a dust collector, a sweeping robot and the like.
Fig. 1 is an exploded view of a sterilization device and a roller brush assembly according to an embodiment of the present invention; FIG. 2 is a longitudinal sectional view of a sterilization device and a roller brush assembly according to an embodiment of the present invention; fig. 3 is a cross-sectional view of a sterilization device and a brush roll assembly according to an embodiment of the present invention. Referring to fig. 1 to 3, the sterilization apparatus provided in this embodiment includes a housing 10 and a sterilization assembly 20.
Specifically, the housing 10 encloses a cavity 11 for receiving the brush roll assembly 30, and the housing 10 is adapted to be detachably coupled to the brush roll assembly 30. The housing 10 may be made of plastic or other corrosion resistant material. The housing 10 may have a connector therein for detachable or movable connection with the brush roll assembly 30, for example, the housing 10 may have a snap (not shown) therein for connection with the brush roll assembly 30, which snap preferably retains the brush roll assembly 30 in the installed position, but may have a release position to facilitate disengagement of the brush roll assembly 30 from the snap. Optionally, a slot (not shown) matching the cross-sectional shape of the roller brush assembly 30 may be formed in the housing 10, and the roller brush assembly 30 may be inserted into the slot to maintain the roller brush assembly 30 at the installation position, and after the roller brush assembly 30 is sterilized, the roller brush assembly may be directly separated from the slot. Of course, there are many ways to connect the rolling brush assembly 30 and the housing 10, and this embodiment is not limited.
In some embodiments, the disinfecting device is part of the cleaning apparatus and is arranged separately from the floor brush of the cleaning apparatus. When the cleaning device is used normally, the rolling brush assembly 30 is arranged in the floor brush, and when the rolling brush assembly 30 needs to be sterilized, the rolling brush assembly 30 can be taken out from the floor brush and installed in the sterilizing device.
In other embodiments, the disinfecting device may be a part of a floor brush of a cleaning apparatus, the housing 10 is an outer shell of the floor brush, and the disinfecting assembly 20 can disinfect the floor brush assembly 30 during normal use.
Even further, in some other embodiments, the sanitizing device is an additional device that does not have any connection to the cleaning appliance.
The sterilizing assembly 20 may be provided on an inner wall surface of the housing 10, and the sterilizing assembly 20 includes at least one ultraviolet light source 21. The sterilization assembly 20 may be adhered to the inner wall surface of the housing 10 by an adhesive or fixed to the inner wall surface 12 of the housing 10 by other fixing structure. Preferably, the sterilizing module 20 may extend along the length direction of the inner wall surface 12 of the casing 10 and may extend from one end to the other end of the length direction of the casing 10, so that each position of the length direction of the roll brush assembly 30 can be acted on by the sterilizing module 20. In this embodiment, preferably, the ultraviolet light source 21 may be a lamp strip formed by fixing a plurality of ultraviolet LED lamp beads on a flexible substrate, so as to be fixed on the inner wall surface of the casing 10. Particularly, when the inner wall surface of the housing 10 is an arc-shaped wall, the ultraviolet light source 21 is in the form of a lamp strip, which can reduce the difficulty of fixing the ultraviolet light source 21 and improve the stability after fixing. Of course, the ultraviolet light source 21 may also be not limited to the form of a light strip, and the invention is not limited thereto.
The sterilizing device provided by the embodiment of the invention comprises a shell, wherein the inner wall surface of the shell is provided with the ultraviolet light source, so that the roller brush assembly arranged in the shell can be sterilized, the risk of mildew of the roller brush assembly is reduced, the service life of the roller brush assembly is prolonged, the cleaning and sterilizing effect of the whole cleaning equipment can be improved, and the user experience is improved.
In addition, in the present embodiment, further, in a state where the rolling brush assembly 30 is mounted with the housing 10, the rolling brush assembly 30 is located at a central position of the cavity 11 enclosed by the housing 10. Further, the housing 10 may be cylindrical, in a state where the rolling brush assembly 30 is installed with the housing 10, an axis of the rolling brush assembly 30 coincides with an axis of the housing 10, that is, as shown in fig. 3, a center of a cross section of the rolling brush assembly 30 coincides with a center of a cross section of the cylindrical housing 10, and a component (such as a clip or a slot, etc.) for installing the rolling brush assembly 30 on the housing 10 may be disposed at a middle position of the housing 10, so that the rolling brush assembly 30 can be installed to the middle position of the housing 10, and when the sterilizing assembly is disposed around the rolling brush assembly 30, the sterilizing device can uniformly sterilize the rolling brush assembly 30 in all directions.
Of course, in other embodiments, the cross-sectional shape of the housing 10 may be any shape, such as square, hexagon, oval, triangle, etc., and the invention is not limited thereto.
In some embodiments, as shown in fig. 3, the sterilizing assembly 20 may include an ultraviolet light source 21 and a reflector 22, the ultraviolet light source 21 and the reflector 22 may be respectively fixed on the inner wall surface 12 of the casing 10, and light emitted from the ultraviolet light source 21 can be reflected to the outer surface of the rolling brush assembly 30 through the reflector 22.
Specifically, the reflective member 22 may include at least one of: mirrors, reflective films, reflective coatings, and the like. As long as it is a reflective element capable of reflecting light. The reflecting surface 221 of the reflector 22 may be parallel to the inner wall surface 12 of the casing 10. As shown in fig. 3, the casing 10 is cylindrical, the inner wall surface 12 of the casing 10 is a curved surface, and the reflecting surface 221 of the reflector 22 is a curved surface having a curvature that matches the curvature of the inner wall surface 12. Accordingly, distances from the reflection surface 221 to all places between the roll brush assembly 30 can be made equal, and thus, the reflection surface 221 can reflect the ultraviolet rays to the roll brush assembly 30 according to a predetermined optical path, thereby simplifying the structure to the maximum extent. Furthermore, the whole reflector 22 may be in the shape of an arc sheet, the surface of the reflector 22 facing the inner wall surface 12 of the housing 10 is attached to the inner wall surface 12 of the housing 10, and the reflector 22 may be adhered to the inner wall surface 12 of the housing 10, so that the connection is stable and reliable.
As shown in fig. 3, an end reflection surface 222 may be formed on the reflection member 22 near the proximal end surface of the ultraviolet light source 21, and the end reflection surface 222 may receive the light emitted from the ultraviolet light source 21 and reflect the light emitted from the ultraviolet light source 21 to the roller brush assembly 30. In this way, the light emitted from the ultraviolet light source 21 is not directly incident on the roller brush assembly 30, but the other part of the light is received by the reflector 22 and reflected to the roller brush assembly 30, thereby maximizing the light utilization efficiency.
Preferably, as shown in fig. 3, the number of the ultraviolet light sources 21 is one, the number of the reflecting members 22 is two, and the two reflecting members 22 may be symmetrically disposed at both sides of the ultraviolet light sources 21. The two reflectors 22 are symmetrically arranged on two sides of the ultraviolet light source 21, so that the reflection effects of the two reflectors 22 on the light rays on the left side and the right side of the ultraviolet light source 21 are consistent, and the light rays reflected to the rolling brush assembly 30 are consistent. By providing only one ultraviolet light source 21 and only two reflectors 22, the structure is simple, the number of components is minimized, the cost is low, and the light utilization efficiency is maximized.
As shown in fig. 3, the thick dotted line is a light emitted from the ultraviolet light source 21, the thin dotted line is a light reflected from the reflecting member 22, the range of the included angle 2 α (i.e., the range of the middle portion) is a range in which the light emitted from the ultraviolet light source 21 is directly directed to the roll brush assembly 30, and the light emitted from the two ends of the ultraviolet light source 21 to the middle portion is emitted to the reflecting member 22, and the ultraviolet light is reflected to the roll brush assembly 30 by the reflecting action of the reflecting member 22. The reflector 22 comprises a near end close to the ultraviolet light source and a far end far away from the ultraviolet light source, the part of the light reflected from the near end close to the ultraviolet light source 21 to the far end far away from the ultraviolet light source 21 on the reflector 22 and the part of the light emitted from the ultraviolet light source 21 and directly emitted to the rolling brush assembly 30 are distributed on the outer side wall of the whole rolling brush assembly 30.
It should be noted that, in order to make all the positions of the rolling brush assembly 30 be irradiated to achieve the overall sterilization effect, all the positions in the circumferential direction of the rolling brush assembly 30 need to be irradiated by the ultraviolet light, and in order to achieve the effect, the emission angle and the emission range of the light of the ultraviolet light source 21 are related.
More specifically, in a state where the roll brush assembly 30 is installed with the housing 10, the central portion of the ultraviolet light source 21 and the distal ends of the two reflectors 22 are uniformly distributed around the roll brush assembly 30. That is, the included angle between the middle of the ultraviolet light source 21 and the far ends of the two reflectors 22 is 60 °, that is, the connecting line of the three forms an equilateral triangle, and the distance from the reflecting surface 221 of the ultraviolet light source 21 and/or the reflector 22 to the axis of the rolling brush assembly 30 is greater than or equal to the diameter of the rolling brush assembly 30. In this way, the connecting line between the middle part of the ultraviolet light source 21 and the far ends of the two reflectors 22 can surround the rolling brush assembly 30, so that the rolling brush assembly 30 can be surrounded by the direct or reflected light of the ultraviolet light source 21, and thus, all parts of the outer surface of the rolling brush assembly 30 can be irradiated by the light directly emitted from the ultraviolet light source 21 or the light reflected from the reflectors 22, and can be uniformly emitted to all parts of the outer surface of the rolling brush assembly 30, so that the sterilization effect of all parts of the rolling brush assembly 30 is basically consistent.
In addition, the housing 10 of the present embodiment includes a bottom wall 10a, and an upper cover 10b is further disposed on the top of the housing 10, and the upper cover 10b is movably or detachably connected to the housing 10. Specifically, the upper cover 10b may be detachably connected to the housing 10 by a snap, or the upper cover 10b may be hinged to the housing 10, as long as the upper cover 10b can be opened from the top of the housing 10 to expose the cavity 11, and the upper cover 10b can be closed to the top of the housing 10, which is not limited in this embodiment.
At least one end of the brush roll assembly 30 is adapted to be coupled to the bottom wall 10a or the upper cover 10 b. In order to fix the brush roll assembly 30 to the housing 10, the brush roll assembly 30 may be connected only to the bottom wall 10a, or the brush roll assembly 30 may be connected only to the upper cover 10b, or the brush roll assembly 30 may be connected to both the bottom wall 10a and the upper cover 10 b.
In this embodiment, the bottom wall 10a may be adapted to be detachably coupled to one end of the brush roll assembly 30, and/or the upper cover 10b may be adapted to be detachably coupled to the other end of the brush roll assembly 30 b. That is, both ends of the roll brush assembly 30 may be connected to the housing 10, or any one of both ends of the roll brush assembly 30 may be connected to the housing 10, and the other end may be a free end, as long as the roll brush assembly 30 can be fixed in the housing 10, and the embodiment is not particularly limited.
