The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0061] like Figures 1 to 3 As shown, an embodiment of the present invention provides a housing structure for a cleaning device, the housing structure comprising: a base 100, a roller brush cover 200 and a locking assembly 300 for assembling the roller brush cover 200 on the base 100. Further, as Figure 4 As shown, the lock assembly 300 includes: a first lock buckle 310 arranged on the base 100, a second lock buckle 320 slidably arranged on the roller brush cover 200, and a driving member 330 rotatably arranged on the roller brush cover 200; the second lock buckle 320 can slide in a direction close to the base 100 until it is locked with the first lock buckle 310; the driving member 330 is used to rotate under the action of an external force and drive the second lock buckle 320 to slide in a direction away from the base 100 during the rotation process until the second lock buckle 320 and the first lock buckle 310 are unlocked (see Figure 5 ), wherein the direction of the external force is the same as the direction in which the roller brush cover 200 is separated from the base. It should be noted that, Figure 5 The arrows in the figure represent the direction of force.

[0062] With the shell structure of the cleaning device as described above, when the roller brush cover 200 is assembled to the base 100, the second lock buckle 320 is slid in a direction close to the base 100 until the second lock buckle 320 and the first lock buckle 310 are locked together, thereby realizing the assembly of the roller brush 600; when the roller brush 600 needs to be removed from the base 100, an external force is applied to the driving member 330, and the driving member 330 rotates under the driving force of the external force and drives the second lock buckle 320 to slide in a direction away from the base 100 during the rotation until the second lock buckle 320 and the first lock buckle 310 are released, thereby releasing the lock between the roller brush cover 200 and the base 100. And because the direction of the external force is the same as the direction in which the roller brush cover 200 is detached from the base 100, the external force will also drive the roller brush cover 200 to rotate in the direction away from the base 100 while driving the driving member 330 to rotate, so that the roller brush cover 200 is detached from the base 100. It can be seen that the detachment process and the unlocking process of the roller brush 600 are carried out simultaneously. The ergonomic design is simple and quick to operate, saves time and effort, is convenient for users to operate, and improves user experience.

[0063] In some embodiments of the present invention, Figures 4 to 7 As shown, the shell structure also includes: an elastic member 340 disposed between the second lock buckle 320 and the roller brush cover 200, and the elastic member 340 is used to provide a force for the second lock buckle 320 to slide in a direction close to the base 100. As an example, the elastic member 340 is disposed between the end of the second lock buckle 320 away from the base 100 and the roller brush cover 200. When the second lock buckle 320 is driven by the driving member 330 to slide in a direction away from the base 100, the elastic member 340 is in a compressed state. After the roller brush cover 200 is removed from the base 100, the driving member 330 stops driving the second lock buckle 320 to slide in a direction away from the base 100 without being affected by external forces. At this time, the compressed elastic member 340 is reset, pushing the second lock buckle 320 to slide in a direction close to the base 100, so that the roller brush cover 200 can be assembled on the base 100 again.

[0064] Optionally, the elastic member 340 is a spring. Such elastic members 340 are easy to obtain and inexpensive. Of course, the elastic member 340 can also be other elastic structures such as a spring-shaped sheet.

[0065] Further, in some embodiments of the present invention, a first mounting portion 210 is provided on the wall of the roller brush cover 200 (see Figure 7 ), a second mounting portion 321 is provided on the wall of the second lock buckle 320 away from the first lock buckle 310 (see Figure 8 ); the first mounting portion 210 is used to mount the first end of the elastic member 340, and the second mounting portion 321 is used to mount the second end of the elastic member 340, wherein the first end and the second end of the elastic member 340 are relatively distributed. The first mounting portion 210 and the second mounting portion 321 are used to prevent the elastic member 340 from falling off during the sliding process of the second lock buckle 320, so as to ensure the normal disassembly and assembly of the roller brush cover 200.

[0066] Specifically, in some embodiments of the present invention, the first mounting portion 210 is a groove-shaped structure (see Figure 7 ), the second mounting portion 321 is a protruding structure (see Figure 8 ), the first end of the elastic member 340 is located in the first mounting portion 210, and the second end of the elastic member 340 is mounted on the second mounting portion 321 by means of interference fit. This facilitates the assembly and disassembly of the elastic member 340. Of course, in some other embodiments of the present invention, the first mounting portion 210 may also be a protruding structure, the second mounting portion 321 may be a groove structure, the first end of the elastic member 340 is mounted on the first mounting portion 210 by means of interference fit, and the second end of the elastic member 340 is located in the first mounting portion 210. Among them, the second mounting portion 321 may be a cross-shaped cross structure or a cylindrical structure, and the embodiment of the present invention does not specifically limit the structure of the second mounting portion.

[0067] In some embodiments of the present invention, Figures 4 to 7 As shown, the roller brush cover 200 is provided with a guide member 350, and the guide member 350 has a guide channel 350a aligned with the first lock buckle 310; the second lock buckle 320 can slide along the guide channel 350a. The guide member 350 allows the second lock buckle 320 to slide along the target direction (i.e., in the direction close to the base 100 and in the direction away from the base 100), which is conducive to the locking and unlocking between the second lock buckle 320 and the first lock buckle 310. It can be understood that the contour of the guide channel 350a is adapted to the outer contour of the locking end of the second lock buckle 320 (i.e., the end close to the first lock buckle 310) to ensure that the locking end of the second lock buckle 320 slides along the wall of the guide channel 350a, and prevents the sliding direction of the second lock buckle 320 from deviating from the target direction. For example, the cross-sectional shape of the locking end of the second lock buckle 320 is rectangular, and the guide channel 350a is a rectangular hole, and the size of the rectangular hole is equal to or slightly larger than the cross-sectional size of the locking end of the second lock buckle 320. It should be noted here that the elastic member 340 may also be disposed between an end of the second lock buckle 320 close to the base 100 and the guide member 350 .

[0068] Alternatively, if Figure 7 As shown, the guide member 350 is a plate-like structure, both sides of the guide member 350 are connected to the roller brush cover 200, and the guide channel 350a is opened in the middle of the guide member 350. The guide member 350 can be more firmly connected to the roller brush cover 200. For example, Figure 7 As shown, at least two screw columns 220 extending toward the guide member 350 are provided on the roller brush cover 200, and at least one mounting hole 350b is provided on each side of the guide member 350. During installation, the screw rod of the screw passes through the mounting hole 350b of the guide member 350 and is threadedly connected with the corresponding screw column 220, so that the guide member 350 can be installed. Optionally, the thickness of the middle part of the guide member 350 is greater than the thickness of the two sides.

[0069] Alternatively, if Figure 8 As shown in FIG. 1 , the second lock buckle 320 has a guide slope 320a on the end near the first lock buckle 310. This facilitates the locking end of the second lock buckle 320 to extend into the guide channel 350a of the guide member 350. For example, the guide slope 320a can be set at the bottom of the second lock buckle 320, and the distance between the guide slope 320a and the base 100 is 1 / 4 of the guide channel 350a. Figure 4 As shown, the guide slope 320a gradually increases from top to bottom. For another example, the guide slope 320a can be set at the top of the second lock buckle 320, and the distance between the guide slope 320a and the base 100 is along Figure 3 The shown direction decreases gradually from top to bottom.

[0070] In some embodiments of the present invention, Figure 4 and Fig. 9As shown, the first lock buckle 310 is a groove-shaped structure; the second lock buckle 320 includes: a clamping portion 322 and a first abutting portion 323 connected to each other, the clamping portion 322 is used to be clamped in the first lock buckle 310, and the first abutting portion 323 is used to abut against the driving member 330 during the rotation of the driving member 330. During the rotation of the driving member 330, it abuts against the first abutting portion 323 of the second lock buckle 320, so that the second lock buckle 320 can be pushed to slide in a direction away from the base 100 until the clamping portion 322 is disengaged from the first lock buckle 310.

[0071] As an example, the clamping portion 322 can pass through the guide channel 350a of the guide member 350 and be clamped in the first lock buckle 310, the guide slope 320a is arranged on the end of the clamping portion 322 close to the first lock buckle 310, and the second mounting portion 321 is arranged on the wall of the clamping portion 322 and the first abutting portion 323 away from the second lock buckle 320.

[0072] Alternatively, if Figure 8 As shown, the first abutting portion 323 is located above the clamping portion 322, and the clamping portion 322 protrudes from the first abutting portion 323 toward the base 100. The side wall of the first abutting portion 323 close to the base 100 is used to abut against the guide member 350 to limit the sliding distance of the clamping portion 322 in the direction close to the base 100, so as to prevent the elastic member 340 from causing the clamping portion 322 to extend into the first lock buckle 310 and collide violently with the first lock buckle 310 due to excessive restoring force. The shape of the first abutting portion 323 can be generally "L"-shaped or rectangular.

[0073] In some embodiments of the present invention, Figure 7 As shown, the driving member 330 includes: a toggle portion 331, a rotating portion 332 and a second abutting portion 333 disposed on the toggle portion 331; the toggle portion 331 is used to rotate around the rotating portion 332 under the action of an external force; the second abutting portion 333 is used to abut against the second lock buckle 320 during the rotation of the toggle portion 331 to push the second lock buckle 320 to slide. As an example, the second abutting portion 333 abuts against the first abutting portion 323 of the second lock buckle 320.

[0074] Optionally, a rotating shaft 3321 is provided on the rotating portion 332 , and the roller brush cover 200 and the guide member 350 cooperate to form a shaft cylinder 3322 , and the rotating shaft 3321 is rotatably provided on the shaft cylinder 3322 .

[0075] Alternatively, if Figure 7 As shown, the second abutting portion 333 and the rotating portion 332 are aligned and distributed in the sliding direction of the second lock buckle 320. The structure can be compact while ensuring that the toggle portion 331 has the functions of rotation and abutment.

[0076] Alternatively, if Figure 7As shown, there are two rotating parts 332, and the two rotating parts 332 are located on both sides of the second abutting part 333 in the axial direction of the rotating part 332. In this way, the toggle part 331 can be ensured to rotate smoothly. Among them, the bottom of the rotating part 332 protrudes from the bottom of the second abutting part 333, so that a lock buckle groove is formed between the rotating part 332 and the second abutting part 333, so that the clamping part 322 of the second lock buckle 320 can pass through.

[0077] Specifically, in some embodiments of the present invention, the toggle portion 331 includes a toggle end and a shielding end that are relatively distributed. The toggle end and the shielding end are located on both sides of the rotating portion 332 in the sliding direction of the second lock buckle 320. The toggle end is distributed close to the base 100, and the shielding end is distributed close to the roller brush cover 200. The second abutting portion 333 is used to abut against the second lock buckle 320 during the rotation of the toggle portion 331. When the toggle end of the toggle portion 331 is toggled outward, the toggle portion 331 rotates through the rotating portion 332 and then drives the second lock buckle 320 to slide in a direction away from the base 100 through the second abutting portion 333. The toggle end is distributed close to the base 100, which is convenient for toggle the toggle portion 331 outward. The shielding portion 331b can be used to shield the elastic member 340, the second buckle 400a and other structures to improve the aesthetics.

[0078] Alternatively, if Figures 4 to 6 As shown, the base 100 has a toggle groove 100a adjacent to the toggle end, and the toggle groove 100a is used to provide a toggle space for the toggle end; the roller brush cover 200 has a clearance groove 200a adjacent to the shielding end, and the clearance groove 200a is used to provide a rotation space for the shielding end. The user's finger can be inserted into the toggle groove 100a to toggle the toggle end of the toggle part 331 outward, and also drive the shielding end of the toggle part 331 to rotate in the clearance groove 200a.

[0079] In some embodiments of the present invention, Figure 2 As shown, the housing structure further includes at least one buckle assembly 400, which is used to cooperate with the lock assembly 300 to limit the roller brush cover 200 in different directions; wherein the unlocking direction of the buckle assembly 400 is the same as the direction of the external force. The buckle assembly 400 can improve the installation strength of the roller brush cover 200 on the base 100. As an example, the lock assembly 300 limits the roller brush cover 200 in the vertical direction, and the buckle assembly 400 limits the roller brush cover 200 in the horizontal direction.

[0080] Furthermore, if Figure 2As shown, the first side wall of the roller brush cover 200 is connected to the first side wall of the base 100 through the locking assembly 300; there are two buckle assemblies 400, the second side wall of the roller brush cover 200 is connected to the second side wall of the base 100 through one of the buckle assemblies 400, and the third side wall of the roller brush cover 200 is connected to the third side wall of the base 100 through another buckle assembly 400, the second side wall and the third side wall of the base 100 are distributed on both sides of the first side wall, and the second side wall and the third side wall of the roller brush cover 200 are distributed on both sides of the first side wall. The locking assembly 300 can form a three-point positioning buckle structure with the two buckle assemblies 400, so that the roller brush cover 200 is more firmly connected to the base 100.

[0081] Alternatively, if Fig.10 As shown, the second locking assembly 410 and the third locking assembly 430 include: a buckle 400a provided on the roller brush cover 200 and a slot 400b provided on the base 100, and the buckle 400a is clamped in the corresponding slot 400b. It can be understood that the extension direction of the buckle 400a is the same as the direction of the external force.

[0082] The disassembly and assembly process of the roller brush cover 200 is described below:

[0083] When installing the roller brush cover 200, the buckles 400a on both sides of the bottom of the roller brush cover 200 are simultaneously buckled on the slots 400b on both sides of the bottom of the base 100 to lock the second lock buckle 320. Then, the toggle end of the toggle part 331 is pressed downward and the clamping part 322 of the second lock buckle 320 is clamped in the first lock buckle 310 through the resetting of the elastic member 340 to lock the second lock buckle 320 with the first lock buckle 310, thereby achieving the installation of the roller brush cover 200.

[0084] When removing the roller brush cover 200, the user can push the toggle end of the toggle portion 331 outward, and the toggle end rotates in a direction away from the toggle groove 100a under the action of external force, thereby driving the second abutting portion 333 to rotate. During the rotation process, the second abutting portion 333 pushes the first abutting portion 323 of the second lock buckle 320, so that the first abutting portion 323 moves in a direction away from the base 100, so that the clamping portion 322 of the second lock buckle 320 is separated from the first lock buckle 310, thereby releasing the lock between the second lock buckle 320 and the first lock buckle 310, and then the buckles 400a on both sides of the bottom of the roller brush cover 200 are separated from the clamping grooves 400b on both sides of the bottom of the base 100, and the locks of the second lock buckle assembly 410 and the third lock buckle assembly 420 are released, thereby realizing the removal of the roller brush cover 200.

[0085] Another embodiment of the present invention provides a housing structure for a cleaning device, such as Figure 6As shown, the shell structure includes a base 100, a roller brush cover 200 and a locking assembly 300 for assembling the roller brush cover 200 on the base 100; an anti-collision buffer 230 is provided on the front end outer wall of the roller brush cover 200, and a sealing member 240 is provided at the periphery of the rear end inner wall of the roller brush cover 200; the locking assembly 300 includes a first locking buckle 310 provided on the base 100 and a second locking buckle 320 slidably provided on the roller brush cover 200, and the second locking buckle 320 can slide in a direction close to the base 100 until it is locked with the first locking buckle 310 or slide in a direction away from the base 100 until it is unlocked with the first locking buckle 310.

[0086] As an example, the anti-collision buffer 230 may be a strip structure extending along the width direction of the roller brush cover 200 , and the anti-collision buffer 230 is made of an elastic material, such as rubber.

[0087] As an example, the seal 240 may be a strip-shaped structure extending along the periphery of the inner wall of the rear end of the roller brush cover 200, and the cross section of the seal 240 protrudes toward the roller brush 600 so that the seal 240 contacts the roller brush 600. The seal 240 may be made of a soft material such as rubber. It should be noted that since the surface of the roller brush 600 is a fluff structure, the seal 240 will not affect the free rotation of the roller brush 600 due to its contact with the roller brush 600.

[0088] In the housing structure for cleaning equipment as described above, the anti-collision buffer 230 is used to better protect the roller brush cover 200 from collision with other objects during the cleaning setting and cleaning operation, and plays a protective role for the roller brush cover 200; the seal 240 can contact the surface of the roller brush 600, effectively preventing water or dirt in the roller brush 600 from entering the edge of the base 100 and contaminating the edge of the base 100; the second lock 320 of the lock assembly 300 can lock or unlock with the first lock 310 by sliding itself, so as to facilitate the disassembly and assembly of the roller brush cover 200 on the base 100. It can be seen that the housing structure provided by the present invention can improve its own performance through the cooperation of the anti-collision buffer 230, the seal 240 and the lock assembly 300.

[0089] In some embodiments of the present invention, Fig.11 As shown in FIG. 1 , the distance D between the lower front wall of the anti-collision buffer 230 and the roller brush cover 200 gradually decreases from top to bottom. The anti-collision buffer 230 of this structure can play a guiding role, facilitating the dust in front of the cleaning device to enter the inner side of the roller brush 200. It should be noted that the "front" and "rear" directions referred to in this article are based on Figure 5 The indicated "front" and "rear" directions shall prevail.

[0090] Optionally, the anti-collision buffer 230 has an inclined surface structure or a curved surface structure.

[0091] In some embodiments of the present invention, Fig.11 As shown, the housing structure further includes a roller brush scraper strip 250, which is disposed on the inner side of the front end of the roller brush cover 200 or connected to the anti-collision buffer 230 and extends to the inner side of the front end of the roller brush cover 200. The roller brush scraper strip 250 is used to scrape off the dirty water and dust on the roller brush 600 to prevent the dirty water and dust on the roller brush 600 from being thrown onto the inner wall of the roller brush cover 200.

[0092] Optionally, the roller brush scraper strip 250 may be connected to the front end of the roller brush cover 200 by bonding, screws, etc.; the anti-collision buffer 230 may be connected to the roller brush scraper strip 250 and / or the roller brush cover 200 by bonding, screws, etc. In other implementations, the roller brush scraper strip 250 may be formed on the base 100, may be integrally formed with the base 100, or may be detachably disposed on the base 100, so as to scrape off dirt on the roller brush 211.

[0093] In some embodiments of the present invention, Figure 6 As shown, a mounting protrusion 260 is formed at the periphery of the inner wall of the rear end of the roller brush cover 200, and the sealing member 240 is connected to the mounting protrusion 260 and extends from the free end of the mounting protrusion 260, wherein the free end of the mounting protrusion 260 refers to the other end of the mounting protrusion 260 opposite to the end connected to the roller brush cover 200. The mounting protrusion 260 facilitates the installation of the sealing member 240.

[0094] Optionally, the sealing member 240 is connected to the inner wall or outer wall of the mounting protrusion 260 by bonding, screws or the like.

[0095] Another embodiment of the present invention provides a cleaning device, which includes the housing structure described in any one of the above items.

[0096] As an example, Figure 1 and Figure 2 As shown, the cleaning device further includes: a roller brush 600 , an upright handle 700 , and the upright handle 700 disposed on the top of the upright handle 700 , the roller brush 600 is installed in the roller brush 600 groove of the base 100 , and the base 100 is installed at the bottom of the upright handle 700 .

[0097] For the cleaning device as described above, such as a vacuum cleaner, when the roller brush cover 200 is assembled to the base 100, the second lock buckle 320 is slid in a direction close to the base 100 until the second lock buckle 320 and the first lock buckle 310 are locked together, thereby achieving the assembly of the roller brush 600; when the roller brush 600 needs to be removed from the base 100, an external force is applied to the driving member 330, and the driving member 330 rotates under the drive of the external force and drives the second lock buckle 320 to slide in a direction away from the base 100 during the rotation until the second lock buckle 320 and the first lock buckle 310 are released, thereby releasing the lock between the roller brush cover 200 and the base 100. And because the direction of the external force is the same as the direction in which the roller brush cover 200 is detached from the base 100, the external force will also drive the roller brush cover 200 to rotate in the direction away from the base 100 while driving the driving member 330 to rotate, so that the roller brush cover 200 is detached from the base 100. It can be seen that the detachment process and the unlocking process of the roller brush 600 are carried out simultaneously. The design conforms to ergonomics, is simple and quick to operate, saves time and effort, is convenient for users to operate, and improves user experience; in addition, the cleaning equipment, the anti-collision buffer 230 is used to better protect the roller brush cover 200 from collisions with other objects during the cleaning setting and cleaning operation, and plays a protective role for the roller brush cover 200; the sealing member 240 can contact the surface of the roller brush 600, effectively preventing water or dirt in the roller brush 600 from entering the edge of the base 100 and contaminating the edge of the base 100; the second lock 320 of the lock assembly 300 can achieve locking or unlocking with the first lock 310 by its own sliding, so as to facilitate the disassembly and assembly of the roller brush cover 200 on the base 100. It can be seen that the cleaning device provided by the present invention can improve its own performance through the cooperation of the anti-collision buffer 230, the sealing component 240 and the locking assembly 300.

[0098] As an example, the cleaning device also includes an upright handle 700 operably connected to the base 100. The upright handle 700 can be used to set the handheld portion and the controller, power supply and other modules of the cleaning device. The cleaning device also has structures such as a vacuum suction source, a garbage channel, a roller brush cover 200, a roller brush 600 scraper, a sewage tank 900, a clean water tank 800, a fluid distributor, and a roller brush 600 installed on the base 100. It should be noted that the upright handle 700 is operably connected to the base 100, which means that the upright handle 700 is detachably and / or rotatably connected to the base 100. In addition, the upright handle 700 includes a handheld portion and also includes a mounting portion for mounting components such as a vacuum suction source, a clean water tank 800, and a sewage tank 900.

[0099] The vacuum suction source and the clean water tank 800 can be selectively arranged on the upright handle 700. The sewage tank 900 can be selectively arranged on the upright handle 700 or the base 100. The vacuum suction source is used to generate suction to suck fluids including gaseous fluids and liquid fluids, as well as garbage and dust from the ground into the sewage tank 900 through the garbage channel. The roller brush cover 200 at least partially surrounds the roller brush 600, so that a suction nozzle structure can be formed between the roller brush cover 200 and the roller brush 600. The cleaning device also includes a roller brush 600 motor, which is installed in the base 100 to provide power to the roller brush 600 to drive the roller brush 600 to rotate for mopping the ground. The suction nozzle is connected to the sewage tank 900 through the garbage channel, so that the fluid or garbage on the ground enters the garbage channel through the suction nozzle.

[0100] The cleaning device also includes a fluid distributor. The fluid distributor can be arranged on the upright handle 700 or the base 100, and a preferred method is to arrange it in the base 100. The fluid distributor is connected to the clean water tank 800 through a fluid transmission passage, and is used to transfer the fluid clean water in the clean water tank 800 through a transmission pipeline to the surface of the roller brush 600 or to the surface to be cleaned.

[0101] In order to make the cleaning efficiency of the cleaning device more efficient, a scraping strip of the rolling brush 600 is provided on the cleaning device, and the scraping strip of the rolling brush 600 can be formed on the rolling brush cover 200. In order to facilitate observation of the cleaning effect and the working state of the rolling brush 600, the rolling brush cover 200 can be made into a transparent shape.

[0102] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0103] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
