DETAILED DESCRIPTION

[0034] To make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the embodiments of the present invention will be described clearly and completely in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them.

[0035] Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0037] The current vacuum cleaner generally has a shell, on which a traveling assembly is installed. The traveling assembly includes a control device, a sensor device, a guide assembly and a travel assembly. The sensor device is connected to the control device to feedback the surrounding environment information. The control device is connected to the guide assembly and the travel assembly. The travel path of the guide assembly and the travel assembly is planned according to the surrounding environment information to perform vacuuming operations in a reasonable manner. Before vacuuming, users are generally required to sweep away slightly larger dust particles, and after vacuuming, they need to mop the floor to complete the entire cleaning process.

[0038] The smart cleaner provided by this application is as follows Figure 1-12 As shown, the multifunctional intelligent cleaner has a shell 1, and the shell 1 is equipped with a traveling component to realize intelligent driving. The guide component includes a guide wheel 6, a guide drive, a traveling wheel and a traveling drive. The guide wheel 6 is preferably installed at the front end of the bottom of the shell 1, and the two traveling wheels are installed on both sides of the middle of the shell 1. The corresponding guide drive and traveling drive are installed in the shell 1, and generally use a motor.

[0039] The guide wheel 6 is located in the middle of the front end, and generally adopts a universal wheel, which is convenient for guiding the driving direction of the entire sweeper and can also effectively ensure balance. The driving wheel 7 is the main power source for the entire sweeper, and is distributed on both sides of the fuselage to stably push the equipment to travel. Preferably, the two driving wheels have their own corresponding driving drive components to achieve the coordination of driving steering, that is, the two driving wheels each have a motor. When changing direction, one of the motors receives the command of the control device to make the driving wheel slow down, stop or reverse, and the other driving wheel moves forward relatively quickly or continuously, thereby realizing the change of the travel direction. Furthermore, the driving wheel 7 is installed with a buffer elastic member, such as a spring installed between the bottom of the driving wheel 7 bracket and the bottom wall of the shell 1. The spring can be compressed to facilitate climbing, and can also play a buffering and protective role when external force impacts.

[0040] The sensing device 10 can use multiple photoelectric sensors installed on the side wall surface of the front end of the housing 1. The corresponding side wall surface of the front end of the housing 1 uses an infrared light shield to ensure the normal operation of the sensor. During the travel process, the front sensor can obtain the environmental information ahead as early as possible, so that the control device can make reasonable path planning in time.

[0041] The smart cleaner also includes:

[0042] The cleaning component includes a cleaning drive and a cleaning brush 2. The cleaning drive is installed in the housing 1. The cleaning brush 2 is exposed and installed at the bottom of the housing 1. It is connected to the output end of the cleaning drive and driven by the cleaning drive to rotate horizontally for cleaning. The cleaning component rotates horizontally in contact with the ground under the control of the cleaning drive, thereby achieving the dust cleaning action. Preferably, there are two cleaning brushes 2, which are respectively installed on both sides of the front end of the bottom of the housing 1. In the specific working process, the two cleaning brushes 2 rotate in different directions. From a top-down perspective, the cleaning brush 2 on the left rotates clockwise, and the cleaning brush 2 on the right rotates counterclockwise, so that the two cleaning brushes 2 can gather the dust on the ground inward.

[0043] The dust collection assembly includes a dust box 5 and a negative pressure driving member, both of which are installed in the housing 1. The bottom of the housing 1 is provided with a dust inlet 8 connected to the dust box 5, and the position of the dust inlet 8 corresponds to the cleaning brush 2; the negative pressure driving member is docked with the dust box 5 to generate negative pressure to suck dust into the dust box 5 through the dust inlet 8. Specifically, a motor can be used as a negative pressure driving member and installed at the rear of the dust box 5. The motor drives the blades to rotate at high speed, generating air negative pressure in the dust box 5, so that the dust collected by the cleaning brush 2 is sucked into the dust box 5 through the dust inlet 8.

[0044] When the dust is gathered by the cleaning brush 2 to the dust inlet 8, some of the dust may not be sucked into the dust box 5 in time, and the sweeper has already moved forward to the vehicle entrance and missed the dust. To improve this problem, the dust inlet 8 is set between the two cleaning brushes 2 and at the rear, and a baffle 80 is set behind the dust inlet 8 to enclose the dust so that it can be sucked into the dust box 5. When the sweeper continues to move forward, the baffle 80 can push the gathered dust and keep the dust at the dust inlet 8 until it is sucked into the dust box 5.

[0045] The mopping assembly includes a cleaning disc 3 and a mopping drive, wherein the mopping drive is installed in the housing 1; the cleaning disc 3 is exposed at the bottom of the housing 1, and is in driving connection with the output end of the mopping drive, and is driven by the mopping drive to rotate horizontally for mopping cleaning. Preferably, there are two cleaning discs 3, which are installed side by side horizontally (left and right) at the rear end of the housing 1. After sweeping and vacuuming, the cleaning disc 3 rotates in contact with the ground to complete the mopping operation. At this point, a single sweeper completes the three operations of sweeping, vacuuming and mopping, effectively saving human resources.

[0046] In some embodiments, the top cover 101 of the housing 1 is concave to form a receiving groove 4, and the dust box is detachably arranged in the receiving groove 4; the receiving groove 4 is provided with a docking interface 41 between the dust inlet 8 and the inlet end of the dust box 5. The dust box 5 often needs to be disassembled to dispose of the accumulated dust. In order to facilitate this operation, the dust box 5 is installed by concavely installing the top cover 101 of the housing 1. Compared with installing the dust box 5 inside the housing 1, the dust box 5 in the technical solution of this embodiment is in a relatively exposed position, and the operation is more simplified.

[0047] Specific installation methods: for example, the dust box 5 is connected to the receiving slot 4 using a snap-fit ​​structure; for another example, the dust box 5 is detachably fixed in the receiving slot 4 with the help of other connecting parts, such as screws. All of the above installation methods are possible. In this case, it is preferred to directly drop the dust box 5 into the receiving slot 4, and no other connecting structure is provided between the two, so that the disassembly and assembly are simpler and faster. Preferably, a cover 1011 can be provided on the receiving slot 4, and the cover 1011 can be opened and closed by rotation, and it is flush with the top cover 101 of the outer shell 1, which can not only strengthen the limitation of the position of the dust box 5, but also protect the dust box 5, and is also conducive to maintaining the overall coordination of the appearance of the outer shell 1.

[0048] In some embodiments, the dust inlet 8 extends into the housing 1, and the dust inlet 8 is inclined from bottom to top toward the rear end of the housing 1, and the end face of the dust inlet 8 is inclined downward from front to back; the front ends of the receiving groove 4 and the dust box are both provided with an inclined surface 40 corresponding to the end face of the dust inlet 8, and the docking port 41 and the inlet end of the dust box are both opened on the corresponding inclined surface; the negative pressure driving member is installed at the rear end of the dust box. The negative pressure driving member generates a backward suction force, and the backward inclination of the dust inlet 8 just coincides with the direction of the suction force. The corresponding inclined surfaces of the receiving groove 4 and the dust box can not only cooperate with the dust inlet 8, but also reduce the structural obstruction to the dust entry path, which is conducive to the dust entering the dust box 5 quickly and smoothly.

[0049] In some embodiments, two cleaning discs 3 are installed side by side in a horizontal direction (left-right direction) at the rear end of the housing 1, and the mopping drive member adopts a gear box 9, which has a first gear set 906 and a second gear set 907 that are transmission-connected to the drive motor, and the output ends of the first gear set 906 and the second gear set 907 are respectively transmission-connected to one of the cleaning discs 3 to control the two cleaning discs 3 to rotate in different directions. When viewed from a top-down angle, preferably, the cleaning disc 3 on the left rotates clockwise, and the cleaning disc 3 on the right rotates counterclockwise, and the different rotations of the two cleaning discs 3 are conducive to the stability of the sweeper.

[0050] Preferably, the two cleaning discs 3 are mirror images of each other and are both installed at an angle so that they form an inclination angle with the cleaning surface, and the inclination angle is generally within 30 degrees. Figure 4It can be seen that the outer sides of the two cleaning discs 3 are tilted downward, and the lower position (outer side) of the cleaning disc 3 is in continuous contact with the bottom surface for cleaning during the rotation process, and the tilted rotation of the cleaning disc 3 can convert the friction between the lower position and the ground into a boosting force to help the sweeper move forward. Furthermore, a support column protruding downward is provided at the center of the cleaning disc 3. The setting of the support column enables the cleaning disc 3 to form two contact points with the ground, improving the slippage phenomenon when the lower position of the tilted cleaning disc 3 contacts the ground.

[0051] In order to realize the two cleaning discs 3 rotating in different directions, the present invention preferably adopts the following method: the first gear set 906 and the second gear set 907 are respectively meshed on both sides of the output gear of the driving motor, and the number of gears of the first gear set 906 and the second gear set 907 differ by N, which is an odd number. If the two gear sets are meshed on both sides of the same gear and the number of gears differs by one, then the gears at the ends of the two gear sets must rotate in different ways, as shown in the attached figure. Fig. 9 The first gear set is shown to have one more gear than the second gear set.

[0052] Specifically, the case of the gearbox 9 in this case includes an upper cover 901 and a lower cover 902 which are assembled and fixed, a cavity is formed in the case to install two gear sets, and the middle part of the case is concave, and a sleeve cavity 904 is formed at the concave end surface, and the sleeve cavity 904 is sleeved to install a motor 905. This can simplify the case structure and facilitate the assembly of the motor 905.

[0053] The output shaft of the motor 905 extends horizontally into the cavity in the box, and a first bevel gear 9051 is installed on the output shaft in the cavity, and the first bevel gear 9051 is installed with a second bevel gear 9052 placed horizontally and meshing with it, thereby forming a right-angle transmission relationship, converting the rotation of the motor in the longitudinal plane into the rotation of the horizontal plane. The second bevel gear 9052 has a small cylindrical gear coaxial with it (i.e., the output gear of the driving motor), and the two gear sets are respectively meshed on both sides of the small cylindrical gear. The gear set preferably adopts a coaxial gear 910 composed of a large cylindrical gear and a small cylindrical gear. The coaxial gear 910 of this structure can be staggered up and down while meshing and transmitting, which can reduce the space occupied by the gear set and is conducive to reducing the equipment structure.

[0054] In the process of driving the cleaning disc 3 to rotate, the gears are subjected to the centrifugal force and fluctuate in the longitudinal direction, which will affect the contact between the cleaning disc 3 and the ground. A first balance ring 9010 extending downward can be provided on the upper cover 901 of the gear box, and a second balance ring 909 can be provided on the output wheel meshing with the end of the gear set. There is an equal height gap between the first balance ring 9010 and the output wheel, and there is an equal height gap between the second balance ring 909 and the upper cover 901. The setting of the two gaps will not interfere with the rotation of the output wheel. When the gear fluctuates up and down, the balance ring will contact the corresponding structure to prevent the fluctuation from further increasing, thereby ensuring the stable operation of the equipment.

[0055] A transmission shaft 908 is arranged below the output wheel and passes through the through hole 903 of the lower cover 902 of the gear box. The transmission shaft 908 is generally polygonal. The cleaning disc 3 cooperates with the transmission shaft 908 through the corresponding transmission sleeve 3010. There are many ways to install the cleaning disc 3 at an angle. For example, the mating surface of the transmission sleeve 3010 and the transmission shaft 908 can be made inclined, or the connection between the cleaning disc 3 and the transmission sleeve 3010 can be set to an inclined state.

[0056] In some embodiments, the cleaning disc 3 includes a chuck 301 and a water tank 302; wherein the chuck 301 is provided with a transmission sleeve 3010 that cooperates with the transmission shaft 908 of the output wheel, and the water tank 302 is detachably installed below the chuck 301. For example, a clamping plate 3011 is provided below the chuck 301, and a clamping slot 3022 that can be assembled with the clamping plate 3011 is provided on the water tank 302. The clamping plate 3011 and the clamping slot 3022 are used to make the two snap together, and when disassembling, the water tank 302 can be broken off with a little force to perform the water replenishment operation.

[0057] A cleaning cloth is detachably mounted on the bottom surface of the water tank 302, such as by Velcro, so that the cleaning cloth can be replaced at any time. The water tank 302 is provided with a water replenishment hole 3021 and a water outlet hole 303. The water replenishment hole 3021 is generally arranged on the top surface of the water tank 302, and the water outlet hole 303 is generally arranged at the bottom of the water tank 302. A water seepage member 3031 for draining water to the cleaning cloth is arranged in the water outlet hole 303. The infiltration-type water flow method can continuously drain water to the cleaning cloth, avoiding the disadvantage that a single water hole structure cannot control the water flow rate, and keeping the cleaning cloth in a relatively balanced water state.

[0058] The above description is only the preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications, combinations and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
