Description

Technical Field

[0001] The invention belongs to the technical field of household electrical appliance design, and in particular relates to a power-assisting wheel and induction wheel integrated module and a vacuum cleaner. Background Art

[0002] Mite removal device (also called mite removal vacuum cleaner) is a new household cleaning product. As a household appliance that can sterilize, remove mites and vacuum, when the mite removal vacuum cleaner is working, the bottom suction port contacts the cleaned surface, and the dust, mites and other dirt on the cleaned surface are sucked into the mite removal dust collection cup through the fan. It cleans the dust and mites in household products and disinfects them, providing a more suitable living environment for humans.

[0003] Mite removal vacuum cleaners are often used to clean fabrics such as bed sheets, mattresses, fabric sofas, blankets, etc. These fabrics are subject to friction during use or friction during washing, and the fibers in the fabrics will become entangled with each other to a certain extent, forming hair balls on the surface of the fabrics. When using the mite removal device, it will be difficult to push and pull.

[0004] In order to solve the problem of the difficulty in pushing and pulling the mite remover in the use process in the prior art to a certain extent, the current common mite removers are provided with several small casters to reduce the friction between the mite remover and the cleaning part during the movement. However, the use environment of the mite remover is a flexible working surface such as a mattress or a sofa. The diameter of this caster is small and it is not powered by electricity, so its effect in actual use is not obvious.

[0005] Patent publication number CN117502961A discloses a cleaning device, wherein an encoder is used in the induction wheel assembly (20) to sense the speed and direction of the induction wheel and then control the operation of the power-assisting motor in the power-assisting wheel assembly (10) to achieve the purpose of power-assisting during use. However, the inventors have found that although the aforementioned cleaning device can achieve the power-assisting function on a soft cleaning surface, the induction wheel and the power-assisting wheel are separately arranged, and the distance between the induction wheel and the power-assisting wheel is relatively far. When cleaning the edge of a mattress, the induction wheel is suspended away from the cleaning surface, thereby causing the power-assisting wheel to fail to function under this condition.

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0045] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90° or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0046] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0047] See also Figure 1 and Fig.10 As shown, according to an embodiment of the present invention, a power-assisted wheel and induction wheel integrated module is provided, including a module shell (not labeled in the figure), wherein a first cavity (not labeled in the figure) for assembling a power-assisted wheel assembly 10 and a second cavity (not labeled in the figure) for assembling an induction wheel assembly 20 are formed in the module shell, wherein the power-assisted wheel assembly 10 includes a power-assisted wheel 11 and a power-assisted motor 12 capable of driving the power-assisted wheel 11 to rotate around its wheel axle (i.e., the central axis), wherein the induction wheel assembly 20 includes an induction wheel 21 and a sensing component (not labeled in the figure) for sensing the rotation direction and rotation speed of the induction wheel 21, wherein the power-assisted wheel 11 is coaxial with the wheel axle of the induction wheel 21, and the first cavity and the second cavity are sequentially arranged along the axial direction of the power-assisted wheel 11, and it can be understood that the aforementioned sensing component realizes more precise control of the rotation direction and rotation speed of the power-assisted wheel 11 by real-time sensing and detection of the rotation direction and rotation speed of the induction wheel 21, thereby ensuring precise and effective power assistance of the power-assisted wheel 11.

[0048] In this technical solution, the power-assisting wheel assembly and the induction wheel assembly that are separately and independently arranged in the prior art are integrated into the same module housing, so that the distance between the power-assisting wheel 11 and the induction wheel 21 can be arranged relatively closer. In this way, when the integrated module of the present invention is used to clean the edge of the cleaning object (such as bed sheets, sofas, etc.), the induction wheel 21 is not prone to the hanging phenomenon in the prior art, thereby ensuring the sensing accuracy of the induction wheel 21 and further ensuring the power-assisting effect of the power-assisting wheel 11.

[0049] See Figure 1 As shown, the aforementioned sensing component specifically includes a grating plate 241 and a sensor transmitting end 2442 and a sensor receiving end 2441 located on the left and right sides of the grating plate 241 .

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

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

[0052] In some embodiments, the end cap 321 is snap-fitted to the first housing 31, so that the end cap 321 and the first housing 31 can be assembled and connected as one more conveniently. Figure 3 As shown, in a specific embodiment, a plurality of fixing buckle points 315 are provided on the outer wall surface of the first cover shell 31, and a plurality of hook arms 3214 are provided on the outer wall surface of the end cover 321, and each hook arm 3214 corresponds to each fixing buckle point 315 one by one to form an elastic buckle connection.

[0053] In order to further improve the position accuracy between the end cover 321 and the first cover shell 31, in a specific embodiment, the end cover 321 and the assembly opening 312 are connected inside and outside by a center stop structure, and the center stop structure can be, for example, a limit stop 318 constructed on the inner wall surface of the mouth wall of the assembly opening 312, see Figure 6 shown.

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

[0055] In this technical solution, the acceleration gearbox assembly and the sensing assembly are arranged on the side of the induction wheel 21 away from the power-assisting wheel 11, which can further ensure that the distance between the induction wheel 21 and the power-assisting wheel 11 is smaller, thereby further reducing the probability of the induction wheel 21 being suspended in the air.

[0056] In some embodiments, with the orientation of the power-assisting wheel and induction wheel integrated module in use and the cleaning surface in a horizontal state (for example, a cleaning bed surface) as a reference, an induction wheel bracket 23 is further provided in the accommodating cavity, and the induction wheel 21 can be rotatably supported on the induction wheel bracket 23, and an elastic member 231 is provided between the top wall of the induction wheel bracket 23 and the top wall of the end cover 321, and the elastic member 231 can be implemented by a coil spring, and the induction wheel bracket 23 and the side wall of the end cover 321 are connected to each other. The acceleration gear box assembly is assembled on the induction wheel bracket 23, and the sensing assembly is assembled on the acceleration gear box assembly. The aforementioned anti-sliding connection is specifically, for example, a slide groove extending up and down is arranged on the two opposite inner wall surfaces of the aforementioned end cover 321, and the two opposite outer side surfaces of the induction wheel bracket 23 can be slidably connected to the aforementioned slide groove up and down, and a corresponding limiting protrusion is arranged at the bottom position of the slide groove to prevent the induction wheel bracket 23 from escaping from the bottom notch of the slide groove under the force of the aforementioned elastic member 231.

[0057] In this technical solution, by clamping the elastic member 231 between the induction wheel bracket 23 and the end cover 321 , 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 aforementioned acceleration gearbox assembly, the sensing assembly and the induction wheel bracket 23 are ultimately installed with the end cover 321 as a carrier, that is, the weight of the aforementioned components is applied to the side of the end cover 321 away from the power-assisted wheel 11 in the form of a cantilever bending moment. In order to ensure a smooth snap-on connection between the end cover 321 and the first cover shell 31, the size of the card slot (not marked in the figure) on the hook arm 3214 is slightly larger than the fixed buckle point 315. After the card slot of each hook arm 3214 is snap-connected with each fixed buckle point 315, there is a certain assembly gap between the card slot and the fixed buckle point 315. Under the action of the mass of the aforementioned components, there is a risk of instability between the end cover 321 and the first cover shell 31. Based on this deficiency, in a specific embodiment, in combination with reference to Figure 6 and Fig. 9 As shown, a plurality of positioning posts 313 are formed on the second end surface of the first housing 31 , and a plurality of positioning holes 3211 are formed on the end surface of the end cover 321 facing the second end surface, and each positioning post 313 is interference-fitted into each positioning hole 3211 .

[0059] In this technical solution, by arranging a plurality of positioning columns 313 on the second end face of the first cover shell 31, arranging a plurality of positioning holes 3211 on the end face of the end cover 321 facing the second end face, and inserting each positioning column 313 into each positioning hole 3211 in an interference fit manner, the connection strength between the end cover 321 and the first cover shell 31 can be improved, and the mass force of the acceleration gear box assembly, the sensing assembly and the induction wheel bracket 23 can be prevented from causing the connection between the end cover 321 and the first cover shell 31 to become unstable, deformed or even fail.

[0060] See Figure 1 As shown, in a specific embodiment, the acceleration gearbox assembly includes an acceleration gearbox housing 220, and an input gear shaft 221, an intermediate transmission gear shaft 222 and an output gear shaft 223 are arranged in the acceleration gearbox housing 220. The induction wheel 21 is sleeved on the input gear shaft 221, and the grating plate 241 in the sensing assembly is sleeved with the output gear shaft 223. The acceleration gearbox housing 220 can be specifically formed by a front shell, a middle shell and a rear shell being assembled in sequence along the axial direction of the induction wheel 21. This structure is a prior art, and the present invention will not elaborate on it.

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

[0062] In this technical solution, by providing a positioning ring 314 coaxial with the power-assisting wheel 11 at the open axial end of the bottom side of the first cover shell 31, the position of the first cover shell 31 can be preliminarily positioned when the first cover shell 31 is connected to the bottom shell 100 of the vacuum cleaner, thereby facilitating the assembly of the first cover shell 31 and the bottom shell 100.

[0063] It can be understood that a plurality of fixed connection feet 316 are provided on the outer peripheral wall of the first cover shell 31 so as to realize the detachable connection between the first cover shell 31 and the bottom shell 100 through corresponding threaded parts (such as screws).

[0064] In a specific embodiment, the outer surface of the top wall of the first cover shell 31 is provided with an upwardly protruding air duct support column 319, so that after the power-assisted wheel and induction wheel integrated module of the present invention is assembled with the bottom shell 100, the air duct support column 319 can form a reliable support for the fan assembly 400 (including the corresponding air duct wall) from the bottom side of the fan assembly 400, thereby improving the structural rigidity of the fan assembly 400 and preventing the fan assembly 400 from vibrating excessively during operation.

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

[0066] In some embodiments, an ultraviolet lamp diverging cavity 41 is further formed on the first cover shell 31, and an ultraviolet lamp (not shown and not labeled) is assembled in the ultraviolet lamp diverging cavity 41 to perform ultraviolet sterilization and disinfection on the cleaning object.

[0067] In this technical solution, ultraviolet lamps are further integrated into the power-assisted wheel and induction wheel integrated modules to enrich the functions of the modules while further improving the structural compactness of the modules.

[0068] In some embodiments, a plurality of ultraviolet lamps are provided, and the plurality of ultraviolet lamps are axially spaced apart along the axle of the power-assisted wheel 11, and each of the ultraviolet lamps is integrated on an ultraviolet lamp board 42, and a plurality of light-transmitting holes 411 are constructed on the top wall of the ultraviolet lamp divergence cavity 41, and the ultraviolet lamp board 42 is assembled on the outer top surface of the cavity top wall, and each of the ultraviolet lamps is provided in one-to-one correspondence with each of the light-transmitting holes 411.

[0069] In this technical solution, the ultraviolet lamp board 42 is arranged outside the top wall of the ultraviolet lamp divergence cavity 41, so that only the ultraviolet lamp is in the ultraviolet lamp divergence cavity 41, and the ultraviolet lamp board 42 is located away from the exposed surface, which is beneficial to improving the dustproof, waterproof and other protective effects of the ultraviolet lamp board 42.

[0070] See Figure 6 and Figure 8 As shown, in some embodiments, the ultraviolet lamp divergence cavity 41 extends axially along the axle of the power-assisting wheel 11 and protrudes from the second end of the end cover 321, and a guide rib 412 extending axially along the axle of the power-assisting wheel 11 and protruding from the second end of the end cover 321 is also formed on the outer top surface of the cavity top wall of the ultraviolet lamp divergence cavity 41, and the guide rib groove 3212 extending axially along the axle of the power-assisting wheel 11 is formed on the outer wall surface of the end cover 321, and the guide rib 412 is embedded in the guide rib groove 3212.

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

[0072] In a preferred embodiment, the guide rib groove 3212 and the guide rib 412 are staggered up and down in the vertical direction, that is, in the vertical direction, the guide rib groove 3212 and the guide rib 412 are engaged with each other, which can further improve the connection reliability between the end cover 321 and the first cover shell 31, and further improve the bearing capacity of the end cover 321 (that is, the ability to resist weight bending moment).

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

[0074] In this technical solution, the power-assisting wheel 11 has a hollow blind hole and the power-assisting motor 12 is inserted into the hollow blind hole, thereby reducing the axial size of the power-assisting wheel assembly 10 and making the structure of the vacuum cleaner using it more compact and smaller.
