Description

Technical Field

[0001] The invention belongs to the technical field of sweeping robots, and in particular relates to a sweeping robot with easily replaceable cleaning parts. Background Art

[0002] A sweeping robot, also known as an automatic cleaning machine, smart vacuum cleaner, robot vacuum cleaner, etc., is a type of smart home appliance that can automatically complete floor cleaning in the room. It generally uses brushing and vacuuming to absorb debris on the ground into its own garbage storage box, thereby completing the function of floor cleaning.

[0003] At present, during the cleaning process of traditional sweeping robots, the cleaning parts are often difficult to replace, and the cleaning parts are usually fixed by bolts and other structures. The bolts facilitate the cleaning parts to be better fixed to the sweeping robot and will not loosen or fall off during use. However, the fixing with bolts makes it more complicated to replace the cleaning parts when they need to be replaced. This results in the user being unable to conveniently perform replacement operations when the cleaning parts are worn, damaged, or require specific cleaning for different cleaning scenarios. However, since it is difficult to replace the cleaning parts of existing sweeping robots, this undoubtedly increases the user's cost of use, and therefore needs to be improved. Summary of the invention

[0004] In order to solve the problem of replacing cleaning components proposed in the above background technology, the present invention provides a sweeping robot with easily replaceable cleaning parts.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a sweeping robot with easily replaceable cleaning parts, comprising an upper cover, an outer cover is provided on one side of the upper cover, a lower cover is provided on the side of the outer cover away from the upper cover, a cleaning bar is clamped on the side of the lower cover away from the outer cover, a clamping sleeve is fixedly connected to one side of the cleaning bar, a connecting block is fixedly connected to the inside of the clamping sleeve, a clamping slot is provided inside the lower cover, a clamping block is provided on one side of the clamping slot, an outer ring of the clamping slot is movably connected to the outer ring, a roller is provided on the side of the lower cover close to the cleaning bar, a hydraulic rod is provided inside the outer cover, a tooth plate is fixedly connected to one side of the hydraulic rod, a gear is meshed on one side of the tooth plate, a swing rod is fixedly connected to the side of the gear away from the tooth plate, a connecting rod is rotatably connected to the side of the swing rod away from the gear, and a movable plate is fixedly connected to the side of the connecting rod away from the swing rod.

[0006] Preferably, an inner rod is fixedly connected to a side of the connecting block close to the ferrule, and a first spring is fixedly connected to a side of the inner rod close to the connecting block.

[0007] Preferably, a second spring is fixedly connected to the interior of the outer ring, and a notch adapted to the clamping block is formed on the outer ring of the clamping sleeve.

[0008] Preferably, the gear is fixedly connected to the rocker arm via a fixed shaft, and the movable plate is connected to the outer cover via a sliding rod.

[0009] Preferably, one side of the movable plate is fixedly connected with an electric push rod, and the side of the electric push rod away from the movable plate is fixedly connected with a connecting piece. Through the electric push rod fixedly connected to one side of the movable plate, when the electric push rod is started, the connecting piece can be accurately driven to move, and the connecting piece is pushed by the electric push rod, and then drives the connecting rod on one side. As the connecting rod moves, the circular block can be further driven. At this time, the circular block will rotate according to the specific movement trajectory of the slide groove. This rotation process enables the circular block to cleverly clamp the card plate. When the roller needs to be disassembled and replaced, the movement of the electric push rod drives the connecting piece and the connecting rod to perform corresponding actions, so that the circular block can release the jamming state of the card plate. In this way, the roller can be easily disassembled and replaced, avoiding the situation where the roller is inconvenient to disassemble and replace due to the limitations of the traditional connection method after it is worn. This design not only improves the maintenance convenience of the sweeping robot, but also extends the service life of the sweeping robot.

[0010] Preferably, a connecting rod is provided on a side of the connecting member away from the electric push rod, and a circular block is movably connected to one side of the connecting rod.

[0011] Preferably, a clamping plate is movably connected to a side of the circular block away from the connecting rod, and the clamping plate is fixedly connected to the roller.

[0012] Preferably, a slide groove is provided on one side of the circular block, and a slide rod matching the slide groove is fixedly connected to the inside of the outer cover.

[0013] Preferably, the number of the rollers is set to two, and the number of the cleaning strips is set to two.

[0014] Preferably, a protrusion is fixedly connected to one side of the circular block close to the card plate, and the protrusion is in contact with the card plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The present invention facilitates the effect of quickly disassembling and replacing the cleaning strip by cooperating with structures such as the sleeve, the slot, and the block. When installing the cleaning strip, the sleeve is squeezed inwardly. At this time, the sleeve can be tightly connected and stuck with the block in the slot under the joint action of the connecting block and the first spring. When the cleaning strip needs to be disassembled for replacement, the sleeve is also squeezed inwardly to open the slot and the block. In this process, the operation is simple and convenient. The user can quickly disassemble the cleaning strip and replace it without the aid of complicated tools or cumbersome steps. Compared with the traditional connection method, it can achieve a more convenient and efficient effect.

[0017] The present invention cooperates with structures such as a hydraulic rod, a toothed plate, a gear, and a movable plate to facilitate the adjustment of the height of the roller according to different heights. The toothed plate is driven to move by the setting of the hydraulic rod, and the meshing gears are rotated synchronously while the toothed plate moves. The rotation of the gears drives a fixedly connected swing rod, so that the swing rod drives a connecting rod, and the movable plate is driven by the setting of the connecting rod, so that the movable plate can move up and down in the outer cover. When the movable plate moves up and down, the fixedly connected rollers can move synchronously, so that the overall sweeping robot can be adjusted in height according to different heights, so as to better clean corners.

DETAILED DESCRIPTION

[0026] 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, not all of the embodiments. 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.

[0027] like Figures 1 to 7 As shown, the present invention provides a sweeping robot with easily replaceable cleaning parts, comprising an upper cover 1, an outer cover 111 is provided on one side of the upper cover 1, a lower cover 110 is provided on the side of the outer cover 111 away from the upper cover 1, a cleaning strip 2 is clamped on the side of the lower cover 110 away from the outer cover 111, a clamping sleeve 3 is fixedly connected to one side of the cleaning strip 2, a connecting block 4 is fixedly connected to the inside of the clamping sleeve 3, a clamping slot 7 is provided inside the lower cover 110, a clamping block 8 is provided on one side of the clamping slot 7, an outer ring of the clamping slot 7 is movably connected to an outer ring 9, a roller 11 is provided on the side of the lower cover 110 close to the cleaning strip 2, a hydraulic rod 17 is provided inside the outer cover 111, a toothed plate 18 is fixedly connected to one side of the hydraulic rod 17, a gear 19 is meshed on one side of the toothed plate 18, a swing rod 20 is fixedly connected to the side of the gear 19 away from the toothed plate 18, a connecting rod 21 is rotatably connected to the side of the swing rod 20 away from the gear 19, and a movable plate 22 is fixedly connected to the side of the connecting rod 21 away from the swing rod 20.

[0028] When installing the cleaning strip 2, the card sleeve 3 is squeezed inwards. At this time, the card sleeve 3 can be tightly connected and stuck with the card block 8 in the card slot 7 under the joint action of the connecting block 4 and the first spring 6. In this process, the design of the card sleeve 3 is very clever. It can accurately cooperate with the card block 8 to ensure the firmness of the installation of the cleaning strip 2. When the cleaning strip 2 needs to be disassembled and replaced, the card sleeve 3 is also squeezed inwards to open the slot and the card block 8. In this process, the operation is simple and convenient. The user can quickly disassemble the cleaning strip 2 and then replace it without the aid of complicated tools or cumbersome steps. Compared with the traditional connection method, this design can achieve a more convenient and efficient effect. It not only saves the user's time and energy, but also improves the replacement efficiency of the cleaning strip 2, so that the sweeping robot can always maintain good cleaning performance.

[0029] The gear plate 18 is driven to move by the setting of the hydraulic rod 17. When the gear plate 18 moves, the meshing gear 19 rotates synchronously. The rotation of the gear 19 is driven by the precise movement of the gear plate 18. The rotation of the gear 19 drives the fixedly connected rocker arm 20, so that the rocker arm 20 drives the connecting rod 21. The movable plate 22 is driven by the setting of the connecting rod 21, so that the movable plate 22 can move up and down in the outer cover 111. The up and down movement of the movable plate 22 is the key link of the whole system. It can be adjusted in height according to different needs. When the movable plate 22 moves up and down, the fixedly connected roller 11 can move synchronously, so that the overall sweeping robot can be adjusted in height according to different heights, so as to better clean the corners. This design makes the sweeping robot more flexible and adaptable, and can achieve the best cleaning effect in different environments.

[0030] like Figure 6 , Figure 7 As shown, the inner rod 5 is fixedly connected to the side of the connecting block 4 close to the clamping sleeve 3, the first spring 6 is fixedly connected to the side of the inner rod 5 close to the connecting block 4, the second spring 10 is fixedly connected to the inside of the outer ring 9, the outer ring of the clamping sleeve 3 is provided with a groove matched with the clamping block 8, the gear 19 is fixedly connected to the rocker arm 20 through a fixed shaft, and the movable plate 22 is connected to the outer cover 111 through a sliding rod 23.

[0031] The above scheme is adopted: the inner rod 5 is fixedly connected to the side of the connecting block 4 close to the card sleeve 3. When the connecting block 4 is squeezed by external force, it can operate synchronously through the coordinated setting of the inner rod 5 and the first spring 6 to ensure that the movement of the connecting block 4 can be accurately transmitted to the card sleeve 3, so that the card sleeve 3 can be smoothly connected with the card slot 7, providing stable and reliable protection for the installation of the cleaning strip 2. At the same time, the second spring 10 inside the outer ring 9 can move during the process of the card block 8 being stuck. This moving characteristic enables the second spring 10 to provide a certain elastic buffer when the card sleeve 3 needs to be connected with the card block 8, so that the notch on the card sleeve 3 can be more smoothly connected with the card block 8. In addition, the gear 19 and the rocker arm 20 are fixedly connected to the card block 8. The fixed axis is connected, and when the gear 19 rotates, the operation of the rocker arm 20 can be driven by the setting of the fixed axis. This connection method enables the rotation of the gear 19 to be accurately transmitted to the rocker arm 20, thereby realizing the synchronous movement between the two. Furthermore, the movable plate 22 is connected to the outer cover 111 through the slide bar 23. When the movable plate 22 needs to adjust the height, it can be limitedly moved up and down by the slide bar 23. The setting of the slide bar 23 can not only ensure that the moving direction of the movable plate 22 is accurate, but also limit the moving range of the movable plate 22 to prevent it from excessive movement or deviation. During the operation of the sweeping robot, the height adjustment of the movable plate 22 can adapt to different cleaning scenarios and needs, thereby improving the cleaning efficiency and quality.

[0032] like Figure 5 , Figure 6 As shown, one side of the movable plate 22 is fixedly connected to an electric push rod 16, the side of the electric push rod 16 away from the movable plate 22 is fixedly connected to a connecting member 15, the side of the connecting member 15 away from the electric push rod 16 is provided with a connecting rod 14, one side of the connecting rod 14 is movably connected to a circular block 13, the side of the circular block 13 away from the connecting rod 14 is movably connected to a clamping plate 12, and the clamping plate 12 is fixedly connected to the roller 11.

[0033] The above scheme is adopted: the electric push rod 16 fixedly connected to one side of the movable plate 22 can drive the connecting member 15 to move very accurately when the electric push rod 16 is started. In this process, the movement trajectory of the connecting member 15 can be ensured to be accurate. The connecting member 15 is pushed by the electric push rod 16, and then drives the connecting rod 14 on one side, which can transmit the power of the electric push rod 16 to the circular block 13. As the connecting rod 14 moves, the circular block 13 can be further driven. At this time, the circular block 13 will rotate according to the specific movement trajectory of the slide groove 131. The circular block 13 can accurately clamp the clamping plate 12 while rotating. This clamping state is not only firm and reliable, but also can ensure the stability of the roller 11 during the working process. When the wheel 11 is disassembled and replaced, the movement of the electric push rod 16 drives the connecting piece 15 and the connecting rod 14 to perform corresponding actions. In this process, the various components cooperate well with each other, and the circular block 13 can quickly release the stuck state of the clamping plate 12, so that the roller 11 can be easily disassembled and replaced, avoiding the situation where the roller 11 is inconvenient to disassemble and replace due to the limitations of the traditional connection method after it is worn. This design not only improves the maintenance convenience of the sweeping robot, but also extends the service life of the sweeping robot. It brings users a more convenient and efficient use experience, so that users do not need to worry about the replacement of the roller during the use of the sweeping robot, and can more easily enjoy the cleaning service brought by the sweeping robot.

[0034] like Figure 5 , Figure 6 As shown, a slide groove 131 is opened on one side of the circular block 13, a slide rod adapted to the slide groove 131 is fixedly connected inside the outer cover 111, the number of rollers 11 is set to two, the number of cleaning strips 2 is set to two, and a protrusion is fixedly connected to one side of the circular block 13 close to the card plate 12, and the protrusion is in contact with the card plate 12.

[0035] The above scheme is adopted: a slide groove 131 is opened on one side of the circular block 13, and the circular block 13 can rotate strictly according to the movement trajectory of the slide groove 131. This rotation method has high accuracy and stability. Due to the precise restriction of the slide groove 131, the circular block 13 will not deviate or be unstable during the movement, ensuring that the circular block 13 can accurately perform its function during the movement. The circular block 13 can connect the card plate 12 more efficiently, thereby providing a strong guarantee for the stable connection of the roller 11. The number of rollers 11 and the cleaning strip 2 is set to two. On the one hand, the setting of the two rollers 11 makes the overall sweeping robot more stable and smooth during the movement. Whether on a flat ground or on a slightly undulating terrain, the two rollers 11 can work together to provide stable support and good maneuverability for the sweeping robot. At the same time, the two rollers The synergistic effect of 11 can also provide the sweeping robot with better steering ability, ensuring that it can move smoothly. On the other hand, the presence of the two cleaning strips 2 enables the sweeping robot to cover a wider area during the cleaning process, thereby improving the cleaning efficiency. The two cleaning strips 2 can clean different areas at the same time, greatly increasing the cleaning range of the sweeping robot. In addition, a protrusion is fixedly connected to the side of the circular block 13 close to the card plate 12. Through the setting of the protrusion, the circular block 13 can be more firmly connected and clamped to the card plate 12. The protrusion can cooperate with the card plate 12 to increase the stability and reliability of the connection. When the roller 11 is clamped and connected, the protrusion can provide additional fixing force to prevent the roller 11 from loosening or falling off during operation. The presence of the protrusion provides double protection for the connection of the roller 11, ensuring the normal operation and cleaning effect of the sweeping robot.

[0036] The working principle and use process of the present invention:

[0037] First, when the cleaning strip 2 needs to be replaced, the card sleeve 3 can be squeezed inwardly. Since the connecting block 4 is connected to the inside of the card sleeve 3 and the block 8 and the slot can be opened under the action of the first spring 6, the cleaning strip 2 can be easily disassembled and replaced. When installing, the card sleeve 3 is also squeezed inwardly so that the card sleeve 3 is engaged with the block 8 in the slot 7 through the slot on the surface. In this way, the installation can be completed quickly. The overall disassembly and installation equipment greatly improves the replacement efficiency of the cleaning strip 2, and there is no need to spend a lot of time on the tedious disassembly and installation process. After installation, the sweeping robot can move with the help of the roller 11 to clean every corner. The hydraulic rod 17 inside the outer cover 111 can drive the tooth plate 18 to move. The movement of the tooth plate 18 will drive the gear 19 meshing with it. The gear 19 acts on the tooth plate 18 While rotating downward, the swing rod 20 fixedly connected on one side can drive the connecting rod 21, and then the connecting rod 21 drives the movable plate 22, so that the movable plate 22 moves up and down inside the outer cover 111, and the up and down movement of the movable plate 22 can drive the overall roller 11 to move. In this way, the sweeping robot can adjust to corners of different heights and clean the floor with them. The card plate 12 on the roller 11 can push the connecting piece 15 through the setting of the electric push rod 16. When the connecting piece 15 moves, the connecting rod 14 can be pulled. The pulling of the connecting rod 14 can make the circular block 13 rotate and adjust the angle through the slide groove 131, so that the circular block 13 is more closely connected to the card plate 12. The setting of the circular block 13 makes it easy to fix the roller 11. In the subsequent replacement process of the roller 11, the existence of the circular block 13 can make the replacement operation more convenient.
