Description

[0001] This application is a divisional application of Chinese Patent Application No. 202210595347.X, entitled "A detachable and integral shovel strip structure for cleaning appliances", the content of which is incorporated herein by reference. TECHNICAL FIELD

[0002] The present application relates to the technical field of cleaning equipment, and in particular to a detachable and integral shovel strip structure for a cleaning appliance. BACKGROUND

[0003] Existing floor cleaners are generally classified into two branches: the air dust circulation technology represented by vacuum cleaners and the water dust circulation technology represented by drum-type floor washing machines. However, due to the limitations of its working principle, the vacuum cleaner cannot clean some garbage and stains firmly attached to the ground. The "water dust circulation" floor washing machine drives the cleaning cylinder to wipe the ground through the operation of the motor. The cleaning cylinder usually adopts a sponge cylinder structure, and the floor cleaner is also equipped with a water supply system and a water tank to clean the cleaning cylinder, thereby perfectly achieving the cleaning of the ground. In order to clean the cleaning cylinder, a closed cleaning space is usually provided to clean the local drum, and clean water is provided to clean the cleaning cylinder, and then the sewage after cleaning the cleaning cylinder is pumped away.

[0004] The floor cleaner is usually provided with a shovel strip that can contact the ground after the cleaning drum, which facilitates the transportation of garbage to the garbage box under the action of the cleaning drum. The advantage of the shovel strip is that it can reduce the garbage accumulation on the shovel strip and avoid local garbage deposition. Currently, the shovel strip in the floor cleaner product on the market is usually fixed with the shell by glue or formed into an integral structure with the shell through a secondary molding technology. However, the shovel strip contacts the ground during use, and when it frequently contacts uneven ground, it will be worn, resulting in unevenness at the front end of the shovel strip, which can cause incomplete garbage shoveling. At this time, the shovel strip needs to be replaced. The integral shovel strip structure cannot be replaced individually, and when the shovel strip is damaged, the shell needs to be replaced as a whole or returned to the factory for repair, which greatly increases the replacement cost of consumers and manufacturers. On the other hand, the entire shovel strip corresponding to the cleaning drum in the floor cleaner product on the market is not long enough in the direction of rotation of the cleaning drum, which results in insufficient time and distance for fine particle garbage to accumulate in the elongated garbage channel, which is not conducive to the accumulation of fine particle garbage into medium particle garbage in the elongated garbage channel, and is not conducive to the removal of fine particle garbage from the cleaning drum. SUMMARY

[0005] The technical problem solved by the present application is to provide a detachable integral shovel strip structure for a cleaning appliance, which can effectively avoid the phenomenon of incomplete cleaning caused by damage of the shovel strip, improve the convenience of replacement, and prolong the length of the garbage channel formed by the shovel strip corresponding to the cleaning drum, thereby being more conducive to accumulation of fine particle garbage into medium particle garbage in the elongated garbage channel and removal of fine particle garbage from the cleaning drum.

[0062] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0063] This invention provides a detachable, integral shovel structure for cleaning appliances.

[0064] Example 1:

[0065] like Figure 1 - Figure 4 As shown, a detachable integral shovel structure for a cleaning appliance includes a housing 1, a shovel structure 2, and a detachable fixing assembly. The shovel structure 2 includes a shovel bracket 21 and a shovel body 20 connected to the shovel bracket 21. The detachable fixing assembly includes a fixing member 3 and a pressure plate 4, and the fixing member 3 and the pressure plate 4 are detachably connected by bolts 5.

[0066] In this embodiment, the fixing component is a detachable structure. Of course, in actual design or product, it can also be designed as an integrated structure with the cleaning appliance housing. Specifically, the fixing component can consist of two parts: a fixing member and a pressure plate, or it can be an integrated molded structure with a separate fixing plate extending into a pressure plate structure.

[0067] In this embodiment, the shovel support 21 is movably connected to the detachable fixing component through the fixing part. In order to realize the quick disassembly and replacement of the shovel structure 2 without disassembling the cleaning tool housing, the shovel structure 2 realizes the push-pull movement of the shovel structure on the detachable fixing component through the cooperation between the shovel support 21 and the snap-fit ​​part of the detachable component.

[0068] Specifically, such as Figure 1 As shown, the cleaning appliance housing has an opening 25 on its side, which corresponds to the snap-fit ​​part of the detachable fixing component. When assembling the shovel structure 2, the shovel bracket 21 is slid into the opening on the side of the cleaning appliance. The fixing part of the shovel bracket 21 fits perfectly with the snap-fit ​​part of the detachable fixing component, thus realizing the detachable push-pull movable connection of the shovel structure 2.

[0069] In this embodiment, the snap-fit ​​part cooperates with the fixing part. The snap-fit ​​part is preferably a sliding groove 31 provided on the top surface of the fixing member and a groove 411 provided on the pressure plate 4. The fixing member also includes a limiting step 41 that cooperates with the shovel bracket.

[0070] In other embodiments, the snap-fit ​​portion may also be provided on the top surface of the fixing member and on the limiting inclined surface 32 of the fixing member.

[0071] In some other embodiments, the snap-fit ​​portion may also be provided on the retaining inclined surface 32 of the fixing member.

[0072] In this scheme, based on the present embodiment, the clamping part can be a sliding groove or a protrusion, and the corresponding fixed part is designed as a protrusion or a groove, so that the sliding groove and the protrusion / protrusion and the sliding groove cooperate with each other.

[0073] In the present embodiment, the cooperation of the clamping part and the fixed part can be the combination of the outward protrusion or accommodation groove on the top surface or side surface of the fixing member and the outward protrusion or accommodation groove on one end of the pressing plate, which will not be described here.

[0074] As shown in Figure 3 - Figure 4 The fixed part includes a first fixed part 211 and a second fixed part 212, wherein the first fixed part 211 cooperates with the sliding groove 31 of the fixing member 3, and a limiting inclined surface 32 is arranged on one side of the sliding groove 31, and a limiting part 210 is arranged on the corresponding shovel strip support 21 and contacts the limiting inclined surface 32. The second fixed part 212 is provided with a limiting notch 2121 which cooperates with the limiting step 41. The limiting notch 2121 cooperates with the pressing plate 4 to be fixed.

[0075] In the present embodiment, in order to better cooperate the shovel strip structure 2 with the pressing plate 4 and the fixing member 3, the limiting notch 2121 is in the shape of a hook, a first inclined surface is cut out at the sharp position of the hook, the root of the hook is a right angle, and the corresponding end surface of the limiting step 41 is also provided with a second inclined surface, and the root of the limiting step 41 is a right angle. When the limiting notch 211 cooperates with the limiting step 41, the first inclined surface is in close cooperation with the second inclined surface, and when the inclined surfaces cooperate, the cooperation degree is higher than that of the two right angles. Correspondingly, the edge corners of the first limiting part 212 which cooperate with the sliding groove 31 are also designed as inclined surfaces, the limiting part 210 is designed as an inclined surface, and the corresponding limiting inclined surface 32 is also designed as an inclined surface structure matching the same. The cooperation of the above limiting structures of the shovel strip makes the cooperation between the shovel strip structure, the fixing member and the pressing plate more close, and while realizing the detachable arrangement of the shovel strip structure, the curved surfaces in contact between the shovel strip structure and the fixing member and the pressing plate are more conducive to better utilizing the support of each small area in the curved surfaces in contact when the arc surface side of the shovel strip is impacted to absorb the impact.

[0076] When the limiting notch 2121 is arranged close to the pressing plate, it can be connected through, for example, bolts, and the corresponding holes for the bolts are designed on the second fixed part 212. When connected, 211 cooperates with the sliding groove 31, the holes on the fixing member 3, the pressing plate 4 and the second fixed part 212 are matched, and the bolts are locked to realize the movable connection of the shovel strip support 21 and the detachable fixing assembly. When the limiting notch 2121 is arranged away from the pressing plate, it can be movably connected through clamping,

[0077] Of course, the movable connection method of the fastener, pressure plate and shovel bar bracket is not limited to the form described above. Any feasible method that can realize the movable connection of the fastener, pressure plate and shovel bar bracket is within the scope of this solution.

[0078] In this embodiment, as needed, a gap 22 is provided between the shovel support 21 and the shovel body 20. Due to the existence of this gap 22, when the shovel body 20 is deformed by force, it can absorb the deformation and prevent the surface of the shovel body 20 from deforming and affecting the waste conveying.

[0079] In this embodiment, to ensure that the shovel structure 2 forms the guide surface of the cleaning tool roller as a whole, the shovel structure 2 is higher than the top surface of the detachable fixing component. The shovel structure 2 includes two parts: a shovel support 21 and a shovel body 20. Since the shovel support 21 needs to achieve a movable connection with the fixing component 3 and the pressure plate 4, and provide a certain supporting force for the shovel body 20, the shovel support 21 is designed to be made of a rigid material. The shovel body 20, as a garbage guiding mechanism, directly contacts the ground to remove garbage. To improve its friction with the ground and achieve a better cleaning effect, the shovel body 20 is designed to be made of a soft material, such as silicone.

[0080] In this embodiment, the shovel body 20 covers the surface of the shovel support 21. The shovel body 20 also includes a downwardly extending shovel portion 201, which is the end of the shovel body 20 corresponding to the extension portion 213 of the shovel support 21.

[0081] like Figure 3 - Figure 4 As shown, the shovel support 21 is also provided with an extension 213. The shovel body extends in the direction corresponding to the extension 213 and is provided with a shovel section 201. The shovel section is designed as a clearance surface for the cleaning appliance sponge roller, and the curvature of the shovel section is adapted to the arc surface in the housing 1 where the sponge roller is placed.

[0082] In this embodiment, to achieve a detachable connection between the pressure plate 4 and the fixing member 3, and to form an installation space (not shown in the figure) between them, extending counterclockwise from the sliding groove 31 to the root of the limiting step 41 along the outer surface of the fixing member 3 and the pressure plate 4, allowing the shovel bar structure 2 to slide in a push-pull manner, the fixing member 3 is provided with a threaded hole, and the pressure plate 4 is provided with a corresponding chamfered through hole. During assembly, the chamfered through hole of the pressure plate 4 is aligned with the screw hole of the fixing member 3, and then the bolt 5 is passed through the above-mentioned through hole and locked with the threaded hole. After locking, due to the design of the sliding groove 31, the limiting inclined surface 32 and the limiting step 41, an installation space is formed between the fixing member 3 and the pressure plate 4 in a counterclockwise direction from the sliding groove 31 to the root of the limiting step 41 along the outer surface of the fixing member 3 and the pressure plate 4. The shovel bar bracket and the detachable fixing component are movably connected within the installation space.

[0083] To prevent the scraper structure 2 from falling out of the opening in the cleaning appliance, a limiting groove and a locking groove (not shown in the figure) are provided in the fixing part of the scraper bracket 21. Correspondingly, a protrusion corresponding to the limiting groove and a locking slot corresponding to the locking groove are provided in the locking part. There are at least two limiting grooves and protrusions, and one locking groove and one locking slot. During the process of pushing or pulling the scraper structure 2 in, the limiting groove contacts each protrusion in turn until each limiting groove and the corresponding protrusion are completely aligned, that is, it is locked in place. The locking groove and the locking slot are completely aligned in position and shape to form a through groove. At this time, a sliding button is provided at the position of the through groove on the outer end of the housing 1. One end of the sliding button is located on the outer surface of the housing 1, and the other end passes through the through groove to lock the scraper structure 2. When the scraper needs to be replaced due to damage, simply push the sliding button to make the sliding button exit the through groove, and pull out the scraper structure 2 for replacement.

[0084] In the push-pull movable connection structure, in order to facilitate the shovel bracket 21 to be pulled out or pushed in from the side of the cleaning appliance housing, one end of the shovel bracket 21 is provided with a limiting end (not shown in the figure). After the shovel bracket is slid out or pushed in from the side of the cleaning appliance housing, the end face of the limiting end just seals the opening on the cleaning appliance housing, so that the end face of the limiting end is flush with the end face formed between the fixing member and the pressure plate. In order to facilitate the removal of the shovel structure, a certain clearance gap is formed between the other end face of the limiting end away from the cover plate and the fixing member. This gap allows fingers to easily penetrate and pull out or push in the shovel structure.

[0085] In this embodiment, for aesthetic purposes, a decorative panel 25 can be provided on the side of the cleaning appliance. In order to achieve the effect of disassembling the shovel structure without removing the decorative panel, a clearance hole that matches the size of the limiting end and does not affect the disassembly of the shovel support is reserved on the decorative panel. This design allows the shovel structure to be replaced or cleaned without removing the decorative panel when disassembling the shovel structure.

[0086] Optionally, the decorative panel can completely cover the shovel structure inside the cleaning tool. To replace the shovel structure 2, first pry out the decorative panel 25, and then pull it outwards to remove the entire shovel structure 2.

[0087] Optionally, the decorative panel and the scraper structure are detachably connected. The decorative panel completely covers the scraper structure inside the cleaning appliance. When replacing the scraper structure, the scraper structure can be pulled out at the same time when the decorative panel is pulled out. Then, the scraper structure can be removed from the decorative panel to replace the scraper structure.

[0088] To achieve a sealed connection between the shovel bar structure, the fixing member 3, and the pressure plate 4, the inner surfaces of the fixing member 3 and the pressure plate 4 that contact the second fixing part 212 are provided with corresponding protruding ribs (not shown in the figure). The ribs can be one or more. If designed as one, it is most preferably provided in the middle of the inner surfaces of the fixing member 3 and the pressure plate 4 that contact the second fixing part 212. When this structure is designed, the two end faces of the corresponding second fixing part 212 that cooperate with it are respectively provided with recesses that are misaligned with the ribs. When the shovel bar is assembled, the recesses of the shovel bar cooperate with the ribs to achieve a tight fit between the shovel bar and the fixing member 3 and the pressure plate 4. When the rib is designed to have multiple ribs, the corresponding second fixing part 212 is also provided with a recess corresponding to the number of ribs. In this solution, designing multiple ribs is the preferred solution. When a stepped or "W" shaped design is formed, the tightness of the fit between the shovel bar and the fixing part and the pressure plate can be improved. At the same time, without adding other limiting structures, it can also effectively prevent the shovel bar structure 2 from coming out of the installation space.

[0089] In this embodiment, the shovel structure is movably fixed to the cleaning appliance through the installation space formed between the locking pressure plate and the fixing parts. Since the shovel structure is frequently in contact with the ground and is a wear-prone part, or when it accidentally hits a hard object during mopping, it may be damaged or torn due to its soft material. To facilitate timely replacement by consumers when damaged, the shovel structure is designed to be a pull-out and slide-out structure from the installation space. At the same time, an opening is opened on the side of the cleaning appliance for easy removal of the shovel structure. When replacing, simply slide the shovel out from the side opening for direct replacement. This avoids the current problem of requiring the entire cleaning appliance cover to be replaced or consumers being unable to replace it themselves and needing to return it to the factory for repair. It also extends the length of the garbage channel formed by the entire shovel and the cleaning roller in the direction of the cleaning roller's rotation, which is more conducive to the accumulation of fine particles into medium particles in the narrow garbage channel, making it easier to remove fine particles from the cleaning roller.

[0090] Example 2:

[0091] like Figure 5As shown, unlike Embodiment 1, in Embodiment 2, the shovel support 21 is provided with a limiting notch 2121 and a second fixing part 212. The corresponding pressure plate 4 is provided with a limiting step 41 corresponding to the limiting notch 2121 and a groove 411 corresponding to the second fixing part 212. The lower surface of the tip of the second fixing part 212 is provided with an arc-shaped chamfer, and the upper surface of the tip of the second fixing part 212 is provided with a slope. This facilitates pressing the shovel support 21 into the slide rail from top to bottom. During the pressing process, the arc-shaped chamfer on the lower surface of the tip of the second fixing part 212 slides down the outwardly inclined surface of the limiting step 41, and the elasticity of the shovel support 21 firmly secures the second fixing part 212 into the groove 411. When removing the shovel, the slope of the upper surface of the tip of the second fixing part 212 slides on the inclined upper surface of the groove 411, and the elasticity of the shovel support 21 allows the second fixing part 212 to slide upward out of the groove 411. During assembly, align the pressure plate with the screw holes of the fastener, and use bolts to fix and connect the fastener and the pressure plate. After connection, the groove 411 and the slide 31 form two slides that allow the shovel bar to be installed and slide easily. Specifically, after aligning the second fixing part 212 on the shovel bar bracket with the groove 411 and the first fixing part 211 with the slide 31, slide the shovel bar bracket between the groove 411 and the slide 31 to achieve a slidable connection of the shovel bar.

[0092] To achieve a tight and secure fit between the shovel support bracket, the pressure plate, and the fastener, the intersection of the horizontal and vertical end faces of the pressure plate limiting step 41 and the limiting notch 2121 is designed as an inclined plane, and the intersection of the horizontal and vertical end faces of the corresponding limiting notch 2121 is also designed as an inclined plane.

[0093] In this embodiment, the top surface of the fixing member 3 (the surface of the fixing member 3 that contacts the pressure plate 4 is the bottom surface, and the other end is the top surface) and the contact surface of the shovel bracket can be designed with a certain arc to smoothly transition, so that the intersection of the top surface of the fixing member and the contact surface of the shovel bracket forms a certain sharp angle. A notch matching the sharp angle is opened on the corresponding shovel bracket. The matching of the sharp angle and the notch realizes the tight fit and fixation of the shovel bracket and the fixing member.

[0094] In this embodiment, the angle between each inclined plane and the horizontal plane is designed to be 30-60 degrees. The shovel structure 2 and the pressure plate 4 have multiple planar connections, which makes it easier to transmit force in the horizontal and vertical directions when the shovel structure 2 is under force, making the shovel more secure.

[0095] In this embodiment, the second fixing part 212 can also be designed as an extension of the shovel bar bracket. The end of the fixing part 3 near the ground is flush with the end face of the shovel bar bracket 21, and the end face is provided with screw holes. The corresponding end face of the pressure plate connection is also provided with corresponding screw holes. This design ensures that the shovel bar is easy to lock with the pressure plate from the bottom, preventing the bottom from tilting up during operation and thus failing to effectively clean up the garbage.

[0096] In this embodiment, no screw holes are provided on the second fixing part 212, and a slot is provided on the corresponding pressure plate. The second fixing part 212 is inserted into the slot to realize the movable connection between the shovel bar and the pressure plate.

[0097] In this embodiment, in order to prevent the shovel bar bracket from falling off the second sliding groove, as described in Embodiment 1, a limiting groove and a locking groove are provided in the sliding groove, which has been described in detail in Embodiment 1 and will not be repeated here.

[0098] In this embodiment, the shovel can be pulled out laterally from an opening on the side of the cleaning appliance, or after the cleaning roller is disassembled, the shovel can be separated from the slide by applying upward force to the second fixing part 212, thereby removing the shovel.

[0099] Example 3:

[0100] like Figures 6-7 As shown, unlike Embodiment 1 and Embodiment 2, in this embodiment, the second fixing part 212 is provided on the end face of the shovel bar bracket limiting part 210, and a limiting groove 33 is opened on the limiting inclined surface of the fixing part.

[0101] The corresponding shovel blade body and the contact end face of the pressure plate are provided with limiting notches and limiting steps. In this embodiment, the limiting steps and limiting notches can be the structures described in Embodiment 1 and Embodiment 2, or they can be as follows: Figures 6-7 The structure described.

[0102] like Figures 6-7 As shown, the pressure plate is provided with a limiting step 41, and a bevel is cut on the right-angled surface of the limiting step near the blade body. Correspondingly, a limiting notch that cooperates with the limiting step is opened on the blade support, and a limiting bevel corresponding to the bevel of the limiting step is cut at the inner right-angled end of the limiting notch. This design allows the pressure plate and the blade body to cooperate more tightly.

[0103] In this embodiment, both the slide groove and the limiting groove are installed on the fixing member. When pushing in and pulling out for disassembly, it is only necessary to pull out or push in the first fixing part 211 and the second fixing part 212 of the shovel structure from the slide groove 31 and the limiting groove 33 for replacement.

[0104] Example 4

[0105] like Figure 8 As shown, unlike Embodiments 1, 2, and 3, in this embodiment, the first fixing part and the second fixing part are respectively provided on the limiting part of the shovel bar bracket, and the corresponding sliding groove and limiting groove are respectively provided on the limiting inclined surface of the fixing member. In this embodiment, the shovel bar bracket realizes the push-pull movable connection of the shovel bar structure on the detachable fixing assembly through the two fixing parts provided on the limiting part and the two snap-fit ​​parts provided on the fixing member.

[0106] Of course, in order to improve the tight fit between the shovel bar bracket and the fixing member in this embodiment, an anti-detachment part can be provided on the two snap-fit ​​parts of the fixing member. Correspondingly, a matching part corresponding to the anti-detachment part is provided on the two fixing parts of the shovel bar bracket. The anti-detachment part can be any one or more structures such as groove, protrusion, and hook. The corresponding matching part can be any one or more structures such as protrusion, groove, and buckle.

[0107] Based on this embodiment, a corresponding push-pull movable connection structure can also be provided at the contact end between the shovel bar bracket and the top surface of the fixing member. For example, a slide rail can be provided on the top surface of the shovel bar bracket near the top surface of the fixing member, and a corresponding slide track can be started on the top surface of the fixing part. The shovel bar bracket and the top surface of the fixing member can be connected in a push-pull movable manner through the slide rail and the slide track.

[0108] Based on this embodiment, the corresponding shovel body and the contact end face of the pressure plate are provided with a limiting notch and a limiting step. The limiting step and limiting notch in this embodiment can be the structure described in Embodiment 1 and Embodiment 2.

[0109] The shovel structure described in this solution is movably fixed to the cleaning appliance through the installation space formed between the locking pressure plate and the fastener. Because the shovel structure is frequently in contact with the ground and is a wear-prone part, or when it accidentally hits a hard object during mopping, it may be damaged or torn due to its soft material. To facilitate timely replacement by consumers when damaged, the shovel structure is designed to be a pull-out and slide-out structure from the installation space. At the same time, an opening is made on the side of the cleaning appliance for easy removal of the shovel. When replacing, simply slide the shovel out from the side opening and replace it directly. This avoids the current problem of requiring the entire cleaning appliance cover to be replaced or consumers being unable to replace it themselves and needing to return it to the factory for repair. It also extends the length of the garbage channel formed by the entire shovel and the cleaning roller, which is more conducive to the accumulation of fine particles into medium particles in the narrow garbage channel, making it easier to remove fine particles from the cleaning roller.

[0110] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions or combinations can be made to some structures (technical features) in one or more embodiments. Such modifications or substitutions or combinations do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention, unless the possibility of substituting or combining structures (technical features) in different embodiments is explicitly excluded in the embodiments, or such substitutions or combinations are contrary to the overall concept of the invention.
