Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, specifically to a cleaning device and a sweeper. Background Technology

[0002] In today's society, with the rapid development of mechanical automation, mechanization and automation are gradually replacing heavy manual labor. Previously, mops were mostly used for cleaning floors, which was inefficient and the floors didn't dry quickly enough. With technological advancements, floor scrubbers have emerged, saving significant time and labor. Floor scrubbers are generally classified by their operation method into walk-behind and ride-on models, integrating water spraying, scrubbing, and wastewater recovery. An existing patent (CN201510129411.5) describes a floor scrubber including a machine body, a motor, and a base plate. The base plate has front and rear wheels connected to its lower end, serving as support. Brakes are also installed on the front and rear wheels for safe operation. A push handle is located near the rear wheels, allowing manual control of the machine's movement. A water spray nozzle is located at the front of the machine body.

[0003] The existing technology, in order to quickly dry the water stains after floor cleaning, places a rotating sweeping brush at the front and a vacuuming and water-absorbing structure at the rear. The vacuuming and water-absorbing structure can quickly dry the water stains left by the sweeping brush. However, this method causes the dust on the un-dusted floor to mix with the water as the sweeping brush rotates, becoming muddy. Even after vacuuming, dust stains will remain on the floor, resulting in an unsatisfactory cleaning effect. Therefore, it does not meet the current needs. To address this, we propose a cleaning device and sweeping machine. Summary of the Invention

[0004] This invention provides a cleaning device and a sweeper, which offers the following advantages: It solves the problem mentioned in the background art where, in order to quickly dry water stains after floor cleaning, a rotating sweeping brush is positioned at the front and a vacuuming and water-absorbing structure at the rear. While the vacuuming and water-absorbing structure can quickly dry the water stains left by the sweeping brush, this results in dust on the untreated floor mixing with the water as the sweeping brush rotates, becoming muddy. Even with subsequent vacuuming, dust stains remain on the floor, leading to an unsatisfactory cleaning effect.

[0008] As an optional embodiment of the cleaning device described in this invention, the lifting component is configured as an electric push rod, a connecting plate is installed on the top of the lifting component, a connecting shaft is installed on the bottom of the servo motor, a saddle buckle is installed on the side of the connecting plate, and the connecting shaft is fixed between the saddle buckle and the connecting plate.

[0009] As an optional embodiment of the cleaning device described in this invention, the following is provided: a connecting frame is installed at the bottom of the lifting component; the mopping sponge is disposed in the middle of the connecting frame; two mopping sponges are disposed in the middle of the connecting frame; a dual-axis motor is installed in the center of the connecting frame; the two output shafts of the dual-axis motor are respectively connected to the two mopping sponges; auxiliary wheels are rotatably installed on both sides of the connecting frame; and the dual-axis motor is connected to the auxiliary wheels.

[0010] As an optional solution of the cleaning device described in this invention, the wringer is configured as a U-shaped plate, the wringer is installed on the side of the wringer frame, and the side of the wringer has a plurality of water-permeable holes. After the lifting component and the central gear are in operation, the mopping sponge is squeezed and adhered to the wringer.

[0011] As an optional embodiment of the cleaning device described in this invention, an auxiliary rod is fixedly installed on the rear side of the protective frame. The auxiliary rod is arranged horizontally and vertically. A drive frame is installed at the bottom of the auxiliary rod. Two traveling wheels are rotatably installed at the bottom of the drive frame. The two traveling wheels are located at both ends of the bottom of the drive frame. Two traveling motors are fixedly installed in the middle of the bottom of the drive frame. The two traveling motors are respectively connected to the two traveling wheels for transmission.

[0012] As an optional embodiment of the cleaning device described in this invention, the drive frame is configured as a rectangular bracket, and protective plates are bolted to the front and rear sides of the bottom of the drive frame, with the walking motor positioned between the two protective plates.

[0015] The present invention has the following beneficial effects:

[0016] 1. This cleaning device and sweeper, through the setting of the mopping sponge, can mop the floor. Through the cooperation of the lifting component and the central gear, when the lifting component moves upward, the mopping sponge moves upward. At this time, the central gear rotates, and the central gear meshes with the two conveyor belts on both sides, causing the two conveyor belts to rotate. Due to the servo motor between the lifting component and the conveyor belt, the mopping sponge moves with the lifting component to the water tank and moves along the arc-shaped servo track to the wringer plate. The mopping sponge comes into contact with the water in the water tank and is squeezed by the wringer plate, so that the mopping sponge is automatically cleaned. When the lifting component returns to its original position with the mopping sponge, the mopping sponge remains clean, thus maintaining the cleaning effect on the floor. At the same time, since the cleaning component is located behind the vacuuming component, the floor is vacuumed first and then mopped. The mopping sponge has less water content after being squeezed, which not only effectively cleans the floor, but also allows the mopping marks to dry quickly, improving the efficiency and quality of floor cleaning.

[0017] 2. This cleaning device and sweeper, by installing a dual-axis motor in the middle of the connecting frame, can increase the number of mopping sponges, improve the cleaning effect of the cleaning components on the ground, and by setting auxiliary wheels to provide support for the connecting frame, the distance between the connecting frame and the ground is fixed, that is, the distance between the dual-axis motor and the ground is maintained, which improves the physical protection of the dual-axis motor, and also reduces the frictional resistance between the mopping sponge and the ground, thus improving the service life of the mopping sponge.

[0018] 3. This cleaning device and sweeper, through the setting of auxiliary rods, drive frame, and walking wheels, improves the support for the protective frame, which in turn improves the support for the entire sweeper, making the sweeper more stable when moving. At the same time, through the cooperation of the walking motor and walking wheels, the sweeper is driven forward by the motor, and the user only needs to control the direction of movement, reducing the physical effort and energy required to use the sweeper, making it more convenient and efficient to use. The setting of the guard plate provides physical protection for the walking motor, maximizing the quality and reliability of the sweeper. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1

[0030] This embodiment aims to address the problem in existing technologies where, to quickly dry water stains after floor cleaning, a rotating sweeping brush 230 is positioned at the front, and a vacuuming and water-absorbing structure is positioned at the rear. The vacuuming and water-absorbing structure can quickly dry the water stains left by the sweeping brush 230. However, this method results in dust on the un-dusted floor mixing with water as the sweeping brush 230 rotates, becoming muddy. Even after vacuuming, dust stains remain on the floor, making it dirtier the more you mop, resulting in a less than ideal cleaning effect. Please refer to [link to relevant documentation]. Figures 1-8 A cleaning device and a sweeper are disclosed. The sweeper includes a cleaning device, which comprises a cleaning component 100 and a vacuuming component 200. The cleaning component 100 includes a water tank 110 and a protective frame 180 installed on the outside of the water tank 110. Figure 1 The water tank 110 is a rectangular stainless steel tank filled with cleaning solution. The protective frame 180 is an aluminum alloy bracket used to support the water tank 110 and provide impact protection for its corners. The bottom of the protective frame 180 is equipped with casters 190 for the sweeper to move and change direction.

[0031] See Figure 2 and Figure 3 The top of the protective frame 180 is bolted to a movable mounting plate 140. A housing 150 is mounted on the upper side of the movable mounting plate 140. Two steering wheels 141 are provided on the side of the movable mounting plate 140. For specific configuration, see [link to relevant documentation]. Figure 6 The rudder 141 is configured with an arc-shaped groove. A central gear 142 is rotatably mounted in the middle of the motorized fixed plate 140. The central gear 142 is a gear driven by a motor, and the motor of the central gear 142 is mounted on the lower side of the housing 150. Fixed shafts 143 are rotatably mounted at the head and tail of the rudder 141. A conveyor belt 144 is sleeved on the outer side of the two fixed shafts 143. The conveyor belt 144 is a chain. A servo motor 162 is mounted on the side of the conveyor belt 144, and the conveyor belt 144 meshes with the central gear 142. A servo motor 162 is slidably mounted in each rudder 141. A lifting component 160 is connected to the bottom of each servo motor 162. When the central gear 142 is driven to rotate by the motor, it will drive the conveyor belt 144 to rotate, thereby driving the lifting component 160 to move.

[0032] See Figure 8In this embodiment, the lifting component 160 is configured as an electric push rod, or it can be configured as a cylinder. A connecting plate 161 is installed on the top of the lifting component 160, and a connecting shaft 163 is installed on the bottom of the servo motor 162. A saddle buckle 164 is bolted to the side of the connecting plate 161, and the connecting shaft 163 is fixed between the saddle buckle 164 and the connecting plate 161. A mopping sponge 170 is rotatably installed on the bottom of the lifting component 160, and a dust collection assembly 200 is installed on the front side of the water tank 110.

[0033] See Figure 5 A water-squeezing bracket 120 is installed inside the water tank 110, and a water-squeezing plate 130 is installed on the side of the water-squeezing bracket 120. Specifically, the water-squeezing plate 130 is set as a U-shaped plate and installed on the side of the water-squeezing bracket. Several water-permeable holes 131 are distributed on the side of the water-squeezing plate 130. After the lifting component 160 and the central gear 142 are running, the mopping sponge 170 is squeezed and adhered to the water-squeezing plate 130. An arc-shaped transmission component 145 is usually installed in the middle. An auxiliary gear 146 is rotatably installed on the inner side of the steering wheel 141. The arc-shaped transmission component 145 slides and adheres to the inner wall of the conveyor belt 144. The auxiliary gear 146 is set on the outer side of the arc-shaped transmission belt. The outer wall of the conveyor belt 144 meshes with the auxiliary gear 146, which helps the conveyor belt 144 maintain the same shape and curvature as the steering wheel 141, ensuring that the servo motor 162 always moves in the steering wheel 141.

[0034] The mopping sponge 170 can mop the floor. Through the cooperation of the lifting component 160 and the central gear 142, when the lifting component 160 moves upward, the mopping sponge 170 moves upward. At this time, the central gear 142 rotates and simultaneously engages with the two conveyor belts 144 on both sides, causing the two conveyor belts 144 to rotate. Since there is a servo motor 162 between the lifting component 160 and the conveyor belts 144, the servo motor 162 causes the mopping sponge 170 to rotate 90 degrees. Then, through the gears and chains, the mopping sponge 170 is moved into the water tank 110. Then, the mopping sponge 170 rotates to wash. After completion, the wringer 130 in the water tank 110 dehydrates the mopping sponge 170.

[0035] With the cleaning component 100 in place, the mopping sponge 170 moves into the water tank 110 along the lifting component 160 and moves along the track of the arc-shaped steering wheel 141 to the wringing plate 130. The mopping sponge 170 comes into contact with the water in the water tank 110 and is squeezed by the wringing plate 130, so that the mopping sponge 170 is automatically cleaned and dehydrated, keeping the mopping sponge 170 clean and thus improving the cleaning effect on the floor.

[0036] In this embodiment, see Figure 1The vacuuming assembly 200 includes a main door frame 210 and a sweeping brush 230 installed at the bottom of the main door frame 210. Specifically, a drive motor is installed inside the main door frame 210, and the output shaft of the drive motor is connected to the sweeping brush 230, allowing the sweeping brush 230 to rotate while the vacuum cleaner moves, thus achieving the function of sweeping the floor. Simultaneously, a vacuum cleaner 240 is installed on the upper side of the main door frame 210. The pipe of the vacuum cleaner 240 is connected to the center of the sweeping brush 230, allowing the dust collected by the sweeping brush 230 to be directly sucked away by the vacuum cleaner 240 through the pipe, achieving the function of dust removal. The main door frame 210 contains a dustbin for collecting dust. The dustbin has dimensions of 235mm*122mm*90mm and a capacity of approximately 2580ml, far exceeding the capacity of dustbins on the market, thus eliminating the need for frequent emptying of the dustbin.

[0037] Meanwhile, to reduce wear during normal movement, a lifting motor 250 is installed on the side of the protective frame 180. The output shaft of the lifting motor 250 is connected to a lead screw 260 via a coupling. The lead screw 260 is threaded into the main door frame 210. At the same time, the main door frame 210 is slidably connected to the protective frame 180 via a sliding groove. The whole assembly forms an electric lead screw slide table. The main door frame 210 can move up and down along the protective frame 180. When sweeping is not required, the main door frame 210 moves upward, causing the sweeping brush 230 to be lifted off the ground, thereby reducing wear.

[0038] In this embodiment: Since the cleaning component 100 is located behind the vacuuming component 200, the floor is vacuumed first and then mopped. Furthermore, the mopping sponge 170 is compressed, reducing its water content, effectively cleaning the floor and allowing the mopping marks to dry quickly, thus improving cleaning efficiency and quality. The mopping sponge 170 allows for mopping, and through the cooperation of the lifting component 160 and the central gear 142, when the lifting component 160 moves upward, the mopping sponge 170 moves upward, and the central gear 142 rotates. Simultaneously, the central gear 142 meshes with the conveyor belts 144 on both sides for transmission. This causes the two conveyor belts 144 to rotate. Since there is a servo motor 162 between the lifting component 160 and the conveyor belt 144, the mopping sponge 170 moves with the lifting component 160 into the water tank 110 and moves along the track of the arc-shaped servo 141 to the wringing plate 130. The mopping sponge 170 comes into contact with the water in the water tank 110 and is squeezed by the wringing plate 130, so that the mopping sponge 170 is automatically cleaned and dehydrated. When the lifting component 160 returns to its original position with the mopping sponge 170, the mopping sponge 170 can automatically clean itself, thereby maintaining the cleaning effect on the floor and avoiding the situation where the floor gets dirtier the more it is mopped.

[0039] Example 2

[0040] This embodiment aims to address the issue that sweeping machines should not be too large, otherwise they will be inconvenient to use, and to improve the utilization rate of the mopping sponge 170. This embodiment is an improvement based on Embodiment 1. For details, please refer to [link / reference]. Figures 1-8 The bottom of the lifting component 160 is equipped with a connecting frame 165, which is a C-shaped frame. In this embodiment, the mopping sponge 170 is actually a cleaning head for a mop made of PVA (polyvinyl alcohol) foam, which has a super water absorption capacity, ten times that of ordinary sponges. The mopping sponge 170 is located in the middle of the connecting frame 165, and there are two mopping sponges 170 in the middle of the connecting frame 165.

[0041] In the specific configuration, a dual-axis motor 171 is installed in the center of the connecting frame 165. In this embodiment, the dual-axis motor 171 can be a miniature high-precision single / dual-axis stepper motor STP-28D1020. The two output shafts of the dual-axis motor 171 are respectively connected to two mopping sponges 170, which not only increases the number of mopping sponges 170, but also provides power for each mopping sponge 170, effectively improving the utilization rate of the mopping sponges 170. The mopping sponge 170 is designed as a cylindrical tube, and the mopping sponge 170 is sleeved on the outside of the output shaft of the dual-axis motor 171, and the outside of the dual-axis motor 171 is wrapped with a waterproof plastic film. Auxiliary wheels 172 are rotatably mounted on both sides of the connecting frame 165. The auxiliary wheels 172 are vulcanized rubber wheels. The dual-axis motor 171 is connected to the auxiliary wheels 172 for transmission. The auxiliary wheels 172 provide support for the connecting frame 165, so that the distance between the connecting frame 165 and the ground is fixed, that is, the distance between the dual-axis motor 171 and the ground is maintained, which improves the physical protection of the dual-axis motor 171. At the same time, it also reduces the frictional resistance between the mopping sponge 170 and the ground, and improves the service life of the mopping sponge 170.

[0042] In this embodiment: by installing a dual-axis motor 171 in the middle of the connecting frame 165, the number of mopping sponges 170 can be increased, improving the cleaning effect of the cleaning component 100 on the ground. Furthermore, the auxiliary wheel 172 provides support for the connecting frame 165, ensuring a fixed distance between the connecting frame 165 and the ground, i.e., maintaining a distance between the dual-axis motor 171 and the ground. This improves the physical protection of the dual-axis motor 171 and also reduces the frictional resistance between the mopping sponge 170 and the ground, thereby increasing the service life of the mopping sponge 170.

[0043] Example 3

[0044] This embodiment aims to address the problem that robotic vacuum cleaners occupy a certain amount of space, are relatively heavy, and require significant physical effort to move. This embodiment is an improvement upon Embodiment 2. For details, please refer to [link to Embodiment 2]. Figures 1-8 An auxiliary rod 310 is fixedly installed on the rear side of the protective frame 180, see Figure 2 Multiple auxiliary rods 310 are provided, and the auxiliary rods 310 are set horizontally and vertically. A drive frame 320 is bolted to the bottom of the auxiliary rods 310. The drive frame 320 is set as a rectangular bracket. Two walking wheels 330 are rotatably installed at the bottom of the drive frame 320. The walking wheels 330 are set as silent rubber wheels.

[0045] In a specific configuration, two traveling wheels 330 are located at both ends of the bottom of the drive frame 320, and two traveling motors 340 are fixedly installed in the middle of the bottom of the drive frame 320. The two traveling motors 340 are respectively connected to the two traveling wheels 330 through couplings.

[0046] The front and rear sides of the bottom of the drive frame 320 are bolted with guard plates 350, which are made of PVC board, and the walking motor 340 is located between the two guard plates 350.

[0047] In this embodiment: the auxiliary rod 310, drive frame 320 and walking wheel 330 improve the support for the protective frame 180, which in turn improves the support for the entire sweeper, making the sweeper more stable when moving. At the same time, through the cooperation of the walking motor 340 and the walking wheel 330, the sweeper is driven forward by the motor. The user only needs to control the direction of movement, reducing the physical effort and energy required to use the sweeper, making it more convenient and efficient to use. The protective plate provides physical protection for the walking motor 340, maximizing the quality and reliability of the sweeper.
