Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of life appliance design, specifically relates to a power-assisted wheel and induction wheel integrated module and dust collector. BACKGROUND

[0002] The mite-removing instrument (also called mite-removing dust collector) is a newly emerging household cleaning product. As a household appliance capable of sterilizing, removing mites and dusting, the mite-removing dust collector contacts the bottom dusting port with the cleaned surface during operation, and the dust, mites and other dirt on the cleaned surface are sucked into the mite-removing dust cup by the fan. The dust and mites in the cleaning household product are cleaned and disinfected, providing a more suitable environment for human survival.

[0003] The mite-removing dust collector is often used to clean bed sheets, mattresses, cloth sofas and blankets. The fibers in the fabric are intertwined to some extent during use or washing, forming a ball on the surface of the fabric. During use, the mite-removing instrument may be difficult to push and pull.

[0004] In order to solve the problem of difficulty in pushing and pulling the mite-removing instrument during use in the prior art, the mite-removing instrument currently commonly used is provided with several small casters to reduce the friction between the mite-removing instrument and the cleaning part during movement. However, the working surface of the mite-removing instrument is a bed or a sofa with elasticity. The diameter of such casters is small, and they are not powered. Therefore, they do not have a significant effect in actual use.

[0005] The patent with publication number CN117502961A discloses a cleaning device. The encoder in the induction wheel assembly (20) senses the speed and direction of the induction wheel and controls the operation of the power-assisted motor in the power-assisted wheel assembly (10) to achieve the power-assisted purpose during use. However, the inventor finds that although the aforementioned cleaning device can achieve the power-assisted function on a soft cleaning surface, the induction wheel and the power-assisted wheel are separately arranged, and the distance between the induction wheel and the power-assisted wheel is far. When cleaning the edge of the bed, the induction wheel is suspended away from the cleaning surface, which causes the power-assisted wheel to not work under this working condition. SUMMARY

[0045] For purposes of the description hereinafter, spatial relations terms, such as "above", "below", "upper", "lower", and the like, can be used with respect to the device and / or features described herein. It will be understood that the spatial terms are intended to encompass different orientations of the device in use or operation in addition to the orientations depicted in the figures. For example, if the device described herein is inverted consistent with the use or operation of the device, then the descriptions of "above" and "below" can be reversed. Accordingly, the example term "above" can encompass both an orientation of above and below. The device can be otherwise oriented (rotated 90° or at other orientations) and the spatially relative terms used herein interpreted accordingly.

[0046] In addition, it should be noted that the use of "first", "second", and the like words of distinction do not connote any meaning of importance, but are used only to distinguish one element from another, and are used subject to change only the context. Consequently, the use of such terms in the context of the present application are not intended to limit the scope of the application, unless otherwise indicated.

[0047] Referring to Figure 1 and Figure 10 According to the embodiment of the present application, a power-assisted wheel and induction wheel integrated module is provided, which comprises a module shell (not marked in the figure), a first cavity (not marked in the figure) for assembling a power-assisted wheel assembly 10 and a second cavity (not marked in the figure) for assembling an induction wheel assembly 20 are formed in the module shell, the power-assisted wheel assembly 10 comprises a power-assisted wheel 11 and a power-assisted motor 12 capable of driving the power-assisted wheel 11 to rotate around its wheel shaft (i.e. central shaft), the induction wheel assembly 20 comprises an induction wheel 21 and a sensing assembly (not marked in the figure) for sensing the rotation direction and rotation speed of the induction wheel 21, the wheel shafts of the power-assisted wheel 11 and the induction wheel 21 are coaxial, and the first cavity and the second cavity are sequentially arranged along the axial direction of the power-assisted wheel 11. It can be understood that the aforementioned sensing assembly realizes more accurate control of the rotation direction and rotation speed of the power-assisted wheel 11 through real-time sensing and detection of the rotation direction and rotation speed of the induction wheel 21, that is, it ensures the accurate and effective power assistance of the power-assisted wheel 11.

[0048] The technical scheme integrates the power-assisted wheel assembly and the induction wheel assembly which are separated from each other in the prior art into the same module housing, so that the distance between the power-assisted wheel 11 and the induction wheel 21 can be set relatively closer, so that the induction wheel 21 is less likely to be suspended when the integrated module of the utility model is used to clean the edge position of a cleaning object (such as a bed sheet, a sofa, etc.), thereby ensuring the induction accuracy of the induction wheel 21 and ensuring the exertion of the power-assisted effect of the power-assisted wheel 11.

[0049] Specifically referring to Figure 1 As shown in the figure, the aforementioned sensing assembly specifically includes a grating plate 241 and a sensor transmitting end 2442 and a sensor receiving end 2441 on the left and right sides of the grating plate 241.

[0050] Specifically referring to Figure 4 As shown in the figure, in one specific embodiment, the module housing includes a first cover 31 and a second cover 32, the first cavity is configured on the first cover 31, the second cavity is configured on the second cover 32, along the axial direction of the power-assisted wheel 11, the first end of the first cover 31 has an end plate 311, the second end of the first cover 31 is an assembly opening 312, the second cover 32 includes an end cover 321, the end cover 321 is detachably connected to the second end of the first cover 31 and the end cover 321 can block the assembly opening 312.

[0051] In the technical scheme, the second end of the first cover 31 is designed as an assembly opening 312, and the end cover 321 is detachably connected to block the aforementioned assembly opening 312. Such a design can facilitate the assembly of the power-assisted wheel assembly 10 and the induction wheel assembly 20.

[0052] In some embodiments, the end cover 321 and the first cover 31 are snap connected, so that the end cover 321 and the first cover 31 can be more conveniently assembled and connected as a whole, specifically referring to Figure 3 As shown in the figure, in one specific embodiment, a plurality of fixed buckle points 315 are arranged on the outer wall surface of the first cover 31, and a plurality of hook arms 3214 are arranged on the outer wall surface of the end cover 321, each hook arm 3214 corresponds to each fixed buckle point 315 to form a resilient snap connection.

[0053] In order to further improve the positional accuracy between the end cover 321 and the first cover 31, in one specific embodiment, the end cover 321 and the assembly opening 312 are connected through a centering notch structure inside and outside, for example, the centering notch structure can be a limiting notch 318 configured on the inner wall surface of the mouth wall of the assembly opening 312, referring to Figure 6 As shown in the figure.

[0054] In some embodiments, the induction wheel assembly 20 further comprises an acceleration gear box assembly (not labeled in the figure), and the end cover 321 is formed with a receiving cavity (not labeled in the figure) on the side away from the first shell 31, and the induction wheel 21 is assembled in the receiving cavity, and the acceleration gear box assembly is drivingly connected between the induction wheel 21 and the sensing assembly.

[0055] In the technical solution, the acceleration gear box assembly and the sensing assembly are arranged on the side of the induction wheel 21 away from the booster wheel 11, which can further ensure that the distance between the induction wheel 21 and the booster wheel 11 is smaller, thereby further reducing the probability of the induction wheel 21 being suspended.

[0056] In some embodiments, with the booster wheel and induction wheel integrated module in a state of use and the cleaning surface being horizontal (for example, a cleaning bed surface), the receiving cavity is further provided with an induction wheel support 23, the induction wheel 21 is rotatably supported on the induction wheel support 23, a spring 231 is arranged between the top wall of the induction wheel support 23 and the top wall of the end cover 321, the spring 231 can be implemented by a coil spring, and the induction wheel support 23 is slidingly connected to the side wall of the end cover 321 in a detachable manner, the acceleration gear box assembly is assembled on the induction wheel support 23, and the sensing assembly is assembled on the acceleration gear box assembly. The sliding detachable connection is specifically, for example, a slide groove extending upward and downward is arranged on each of the two inner walls of the end cover 321, and the two outer sides of the induction wheel support 23 are connected to the slide grooves in a sliding manner upward and downward, and a limiting protrusion is arranged at the bottom of the slide groove to prevent the induction wheel support 23 from being detached from the bottom of the slide groove under the force of the spring 231.

[0057] In the technical solution, the spring 231 is clamped between the induction wheel support 23 and the end cover 321, so that the induction wheel 21 can rise and fall with the ups and downs of the cleaning surface, thereby ensuring accurate sensing of the induction wheel 21.

[0058] It is worth noting that, as mentioned above, the acceleration gear box assembly, the sensing assembly, and the induction wheel support 23 are ultimately mounted on the end cover 321, that is, the weight of the components is applied to the side of the end cover 321 away from the booster wheel 11 in the form of a cantilever bending moment, and in order to ensure smooth buckle connection between the end cover 321 and the first shell 31, the size of the clamping groove (not labeled in the figure) on the clamping arm 3214 is slightly larger than that of the fixed buckle point 315. After the clamping groove and the fixed buckle point 315 of each clamping arm 3214 are buckled, there is a certain assembly gap between the clamping groove and the fixed buckle point 315. Under the weight of the components, there is a risk of instability between the end cover 321 and the first shell 31. Based on this deficiency, in one specific embodiment, in combination with reference toFigure 6 and Figure 9 As shown, a plurality of positioning posts 313 are formed on the second end face of the first cover 31, and a plurality of positioning holes 3211 are formed on the side end face of the end cap 321 facing the second end face. Each positioning post 313 is interference-fitted into each positioning hole 3211.

[0059] In this technical solution, by setting multiple positioning posts 313 on the second end face of the first cover 31 and setting multiple positioning holes 3211 on the side end face of the end cover 321 facing the second end face, and inserting each positioning post 313 into each positioning hole 3211 in an interference fit manner, the connection strength between the end cover 321 and the first cover 31 can be improved, and the connection between the end cover 321 and the first cover 31 can be prevented from becoming unstable, deformed or even failing due to the mass force applied by the acceleration gearbox assembly, sensing assembly and sensing wheel bracket 23.

[0060] See details Figure 1 As shown, in a specific embodiment, the acceleration gearbox assembly includes an acceleration gearbox housing 220. An input gear shaft 221, an intermediate transmission gear shaft 222, and an output gear shaft 223 are disposed within the acceleration gearbox housing 220. The sensing wheel 21 is fitted onto the input gear shaft 221, and the grating plate 241 in the sensing assembly is sleeved with the output gear shaft 223. Specifically, the aforementioned acceleration gearbox housing 220 can be formed by sequentially assembling a front shell, a middle shell, and a rear shell along the axial direction of the sensing wheel 21. This structure is prior art and will not be described in detail here.

[0061] In some embodiments, the first housing 31 has a bottom opening (not shown in the figure, see below). Figure 3 As shown), the bottom rim of the booster wheel 11 protrudes from the bottom opening, and a positioning ring 314 is provided at one axial end of the bottom opening, the positioning ring 314 being coaxial with the booster wheel 11.

[0062] In this technical solution, by setting a positioning ring 314 coaxial with the assist wheel 11 at the axial end of the bottom opening of the first cover 31, the position of the first cover 31 can be initially positioned when connecting the first cover 31 to the bottom shell 100 of the vacuum cleaner, thereby facilitating the assembly of the first cover 31 and the bottom shell 100.

[0063] It is understandable that the outer peripheral wall of the aforementioned first cover 31 is provided with a plurality of fixed connecting feet 316, so as to achieve a detachable connection between the first cover 31 and the aforementioned bottom shell 100 by means of corresponding threaded parts (such as screws).

[0064] In a specific embodiment, the top wall outer side of the first cover 31 has an upwardly protruding air duct support column 319, so that after the power-assisted wheel and induction wheel integrated module is assembled with the bottom shell 100, the air duct support column 319 can reliably support the fan assembly 400 (including the corresponding air duct wall) from the bottom side of the fan assembly 400, improve the structural rigidity of the fan assembly 400, and prevent excessive vibration of the fan assembly 400 during operation.

[0065] In another specific embodiment, two cable clamping grooves 317 are further provided on the outer side of the first cover 31 and are arranged along the axial direction of the power-assisted wheel 11, for positioning the cables of the aforementioned power-assisted motor 12 and other related components.

[0066] In some embodiments, an ultraviolet lamp emitting cavity 41 is further formed on the first cover 31, and an ultraviolet lamp (not shown in the figure, not referenced) is assembled in the ultraviolet lamp emitting cavity 41, so as to sterilize and disinfect the cleaning object by ultraviolet rays.

[0069] In this technical solution, the ultraviolet lamp panel 42 is arranged outside the top wall of the ultraviolet lamp emitting cavity 41, so that only the ultraviolet lamp is in the ultraviolet lamp emitting cavity 41, and the ultraviolet lamp panel 42 is away from the exposed surface, which is beneficial to improve the dustproof and waterproof protection effect of the ultraviolet lamp panel 42.

[0070] Specifically referring to Figure 6 and Figure 8 In some embodiments, the ultraviolet lamp emitting cavity 41 extends along the axial direction of the wheel shaft of the power-assisted wheel 11 and protrudes from the second end of the end cover 321, the outer top surface of the top wall of the ultraviolet lamp emitting cavity 41 further forms a guide rib 412 extending along the axial direction of the wheel shaft of the power-assisted wheel 11 and protruding from the second end of the end cover 321, the outer wall surface of the end cover 321 forms a guide rib groove 3212 extending along the axial direction of the wheel shaft of the power-assisted wheel 11, and the guide rib 412 is embedded in the guide rib groove 3212.

[0071] In the technical solution, the sliding fit between the guide ribs 412 and the guide rib grooves 3212 can guide and position the end cover 321 and the first shell 31 during assembly, further facilitating the assembly of the two.

[0072] In a preferred embodiment, the guide rib grooves 3212 and the guide ribs 412 are staggered vertically, i.e., the guide rib grooves 3212 and the guide ribs 412 are engaged vertically, which can further improve the connection reliability between the end cover 321 and the first shell 31 and further improve the load bearing capacity (i.e., the ability to resist the bending moment of the weight) of the end cover 321.

[0073] In some embodiments, the power wheel 11 has a hollow blind hole (not shown in the figure) extending in the axial direction, the power motor 12 is accommodated in the hollow blind hole, and the output shaft of the power motor 12 is coaxial with the wheel shaft of the power wheel 11.
