Description

Technical Field

[0001] The invention relates to the technical field of vacuum cleaners, in particular to a floor brush, a vacuum cleaner, a floor scrubber and a mite remover with a dust display function. Background Art

[0002] The floor brush is a common vacuum component of a vacuum cleaner, floor scrubber or mite remover. The floor brush moves along the surface to clean the surface to be cleaned, which can be a bottom surface, a table top, a bed surface, etc. In order to facilitate users to observe the dirtiness of the surface to be cleaned, thereby reminding users to accurately move the floor brush to improve cleaning efficiency, dust display solutions are currently designed. Some of these dust display solutions use green lasers to illuminate the ground for dust display, which requires laser diodes and lenses, and is relatively expensive. Other solutions use LED light sources, but the cost of dust display is still relatively high by setting lenses or reflectors, and the dust display effect needs to be optimized. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and propose a floor brush with a dust display function, which is conducive to dust display and has low cost; a vacuum cleaner or a floor scrubber or a mite remover is also proposed, including the aforementioned floor brush.

[0004] Compared with the prior art, the present invention proposes a floor brush with a dust display function, comprising a main body and a cleaning component, the cleaning component being installed in the main body, a long dust display light strip is provided at the front end of the main body close to the surface to be cleaned, the dust display light strip comprises a substrate and a plurality of LED lamp beads located on the substrate, the substrate is extended from the middle of the front end to both sides, the LED lamp beads are arranged in one row or multiple rows and are distributed along the length direction of the substrate, at least the setting height of the LED lamp beads in the bottom row relative to the surface to be cleaned is a closed interval of [10, 20] mm, and the substrate is vertically arranged or tilted forward.

[0005] After adopting the above structure, compared with the prior art, the present invention has the following advantages:

[0006] The present disclosure proposes a new design idea, that is, a long dust-displaying light strip is provided at the front end of the main body near the surface to be cleaned, and the dust-displaying light strip includes a substrate and a plurality of LED lamp beads located on the substrate, the substrate is extended from the middle of the front end to both sides, the LED lamp beads are arranged in one row or multiple rows, and are distributed along the length direction of the substrate, at least the setting height of the LED lamp beads in the bottom row relative to the surface to be cleaned is a closed interval of [10, 20] mm, the substrate is arranged vertically or tilted forward, and since the light emitting range of the LED lamp beads is a cone around the LED lamp beads, the LED lamp beads are regarded as the center point, and the plurality of L The light of ED lamp beads overlap to form a light beam with a long strip cross section. The farther away from the substrate, the wider the long strip cross section. Therefore, the vertical setting or forward tilting setting of the substrate determines the irradiation angle of the light beam. Then, using the dust-displaying light strip close to the surface to be cleaned can make the shadow of dust (dust, debris, etc.) longer, making the dust more obvious, that is, at least the setting height of the bottom row of LED lamp beads relative to the surface to be cleaned is a closed interval of [10, 20] mm, and the substrate is vertically set or tilted forward, so that the shadow of the dust is longer by using the part of the light of the long strip light beam that shines on the ground.

[0007] Since the principle used in the present invention is to obtain a long light beam through a dust-displaying light strip, and to make the dust-displaying light strip close to the surface to be cleaned for illumination, so that the dust has a long shadow, so that the dust is sufficiently obvious, the present invention does not need to set a lens or a reflector.

[0008] In some embodiments, a mounting groove is provided at the front end of the body, and the substrate is mounted in the mounting groove.

[0009] In some embodiments, the mounting slot is connected to a light-transmitting cover.

[0010] In some embodiments, a light-transmitting cover is further included. The light-transmitting cover is installed at the front end of the body, and the light-transmitting cover is integrally provided with a mounting groove of the substrate.

[0011] In some embodiments, a slot is provided in the installation groove along the length direction of the substrate, and the substrate is plugged into the slot.

[0012] In some embodiments, the substrate is installed in the installation groove to form a module with the light-transmitting cover.

[0013] In some embodiments, the plurality of LED lamp beads are evenly distributed along the length direction of the substrate.

[0014] In some embodiments, the length of the substrate is set to occupy between one fifth and the same length as the width of the floor brush, including both one fifth and the same length.

[0015] In some embodiments, the substrate is configured as a rigid circuit board or a flexible circuit board. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the present invention defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the present invention.

[0027] Those skilled in the art should understand that, in the disclosure of the present invention, the orientation or position relationship indicated by the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0028] like Figures 1 to 9 The figure shows a floor brush with a dust display function, comprising a body 1 and a cleaning component 2. The cleaning component 2 is installed in the body 1. A long dust display light strip 3 is provided at the front end of the body 1 near the cleaned surface 15. The dust display light strip 3 comprises a substrate 4 and a plurality of LED lamp beads 5 located on the substrate 4. The substrate 4 extends from the middle of the front end to both sides. The LED lamp beads 5 are arranged in one row or multiple rows. Figure 2 , 5 6, the LED lamp beads 5 are arranged in a row and distributed along the length direction of the substrate 4, and the setting height 17 of the LED lamp beads 5 relative to the cleaned surface 15 is a closed interval of [10, 20] mm, wherein Figure 5 , Figure 6 The shown lengths are all 15 mm, and the substrate 4 is arranged vertically or tilted forward. The dust-displaying light strip 3 forms a long strip of light beams, and the farther away from the substrate 4, the wider the light beam cross section 16 is.

[0029] The beam cross section 16 is constrained between the upper irradiation edge line 9 and the lower irradiation edge line 10 . As the lower irradiation edge line 10 intersects the surface 15 to be cleaned, the lower end position of the beam cross section 16 extends along the surface 15 to be cleaned.

[0030] The elongated light beam means that the dimension of the light beam along the width direction of the floor brush is larger than the dimension of the elongated light beam along the height 17 direction of the floor brush, that is, at the substrate 4, the height 17 direction of the light beam is the narrow direction.

[0031] Since there is no lens or reflector, the light beam will become more dispersed and the brightness will decrease as the irradiation distance becomes longer. Therefore, the dust-displaying light strip 3 is set close to the surface to be cleaned 15, and the setting height 17 of the LED lamp beads 5 relative to the surface to be cleaned 15 is a closed interval of [10, 20] mm, and the substrate 4 is set vertically or tilted forward, so that the adverse effects of the lack of lenses or reflectors are reduced, and the shadow of dust debris 13 (dust, debris, etc.) is longer, making the dust debris 13 more obvious.

[0032] In this example, the cleaning component 2 is a roller brush, and the cleaning component 2 may also be a cleaning component of other structural forms.

[0033] In order to suck away the dirt in time, the floor brush is also provided with a suction port 18 located at the rear side of the cleaning component 2, and the suction port 18 is connected to a suction pipe 19, which can be connected to the dirt collection bin of a vacuum cleaner, a floor scrubber, or a mite remover, thereby forming a working part of the vacuum cleaner, the floor scrubber, or the mite remover. For portable use, i.e., handheld use, the mite remover can be considered to be provided with a handle, a dirt collection bin, a filter, a fan, and other structures on the floor brush of the present disclosure, and the suction port 18, the dirt collection bin, the filter, and the fan are connected and arranged in sequence, thereby forming a smaller volume, which is convenient for handheld use.

[0034] The floor brush can be set to a pluggable and detachable structure so that it can be sold independently. When the floor brush is connected to the main unit of a vacuum cleaner or a floor scrubber, it constitutes a complete vacuum cleaner or floor scrubber that can perform cleaning tasks. Other structures of the vacuum cleaner or floor scrubber can adopt existing technologies and will not be elaborated here.

[0035] The length of the substrate 4 is set to between one-fifth and the same length as the width of the floor brush, including the two situations of one-fifth and the same length, that is, the minimum setting is one-fifth, which is helpful to ensure the width of the dust display surface and facilitate user observation.

[0036] For household appliances, in order to have better flexibility in space while ensuring a certain cleaning efficiency, the width of the floor brush is generally controlled at about 250 mm. Therefore, the length of the base plate 4 can be set to be greater than or equal to 50 mm.

[0037] The height 17 of the LED lamp bead 5 can be set from the cleaned surface 15 to the upper edge of the LED lamp bead 5, from the cleaned surface 15 to the center of the LED lamp bead 5, or from the cleaned surface 15 to the lower edge of the LED lamp bead 5. The height 17 of the LED lamp bead 5 can be set to 10 mm, 15 mm, 20 mm, etc. in the closed interval [10, 20] mm.

[0038] like Figure 4 , Figure 6 As shown, when the substrate 4 is arranged vertically, its irradiation center line 11 irradiates forward, and the lower irradiation edge line 10 intersects with the cleaned surface 15 after a certain distance. Then, the dust 13 on the cleaned surface 15 is irradiated by the dust-displaying light beam 12 and displays a longer shadow, thereby forming a shadow area 14.

[0039] like Figure 3 , Figure 5 As shown, when the substrate 4 is tilted forward, its irradiation center line 11 irradiates downward, and the lower irradiation edge line 10 quickly intersects with the cleaned surface 15 after passing a distance.

[0040] As the height 17 increases, the base plate 4 is preferably tilted forward, such as Figure 3 , Figure 5 As shown, a longer shadow is obtained while the lower side illumination edge line 10 is brought close to the front end of the body 1 .

[0041] In some embodiments, the substrate 4 is configured as a rigid circuit board or a flexible circuit board, which is convenient for manufacturing and electrical connection. Of course, other structures are also possible, for example, a mounting seat is provided at the front end of the body 1 near the surface to be cleaned 15, and the mounting seat serves as the substrate 4, and a plurality of LED lamp beads 5 are installed on the mounting seat, thereby realizing a long strip of dust-displaying light strip 3.

[0042] In some embodiments, Figure 1 , 7 As shown, it also includes a light-transmitting cover 7, which is installed at the front end of the body 1. The light-transmitting cover 7 is integrally provided with a mounting groove 6 of the substrate 4, thereby simplifying production.

[0043] In order to further simplify production, such as Figure 7 As shown, a slot 8 is provided in the installation groove 6 and is arranged along the length direction of the base plate 4 , and the base plate 4 is plugged into the slot 8 .

[0044] In order to further simplify the production, the substrate 4 is installed in the installation groove 6 to form a module with the light-transmitting cover 7, that is, the substrate 4 is plugged into the slot 8 to form a module.

[0045] Of course, other structures are also possible, for example, a mounting groove 6 is provided at the front end of the body 1, and the substrate 4 is installed in the mounting groove 6, rather than the mounting groove 6 for the substrate 4 being integrally provided on the light-transmitting cover 7. In this case, in order to protect the dust-displaying light strip 3, the mounting groove 6 needs to be additionally connected to a light-transmitting cover 7. As can be seen from the foregoing, the structure is more complicated than the solution in which the mounting groove 6 for the substrate 4 is integrally provided on the light-transmitting cover 7.

[0046] like Figure 8 , 9 As shown, the LED lamp beads 5 are arranged in two rows, one above the other, so as to form a long strip of light beam with a stronger brightness. Figure 8 As shown in the figure, the upper and lower symmetrical arrangement can also be as shown in the figure. Fig. 9 The two electrodes are arranged offset from each other as shown.

[0047] Based on the full description of the text and drawings of the present disclosure, it is conceivable that the specific number and distribution density of the LED lamp beads 5 can be selected according to the required brightness and the need to form a long strip of light beam. The specific quantification can be obtained through calculation and / or a limited number of experiments, which will not be elaborated here.

[0048] When understanding the present disclosure, if necessary, the above structure can refer to other embodiments / appendices. Figure 1 And understand, no further elaboration here.

[0049] The above description is only an illustrative embodiment of the present invention, so all equivalent changes or modifications made according to the structure, characteristics and principles described in the patent protection scope of the present invention are included in the patent protection scope of the present invention.
