[0055] With the continuous development of technology, smart home devices are playing an increasingly important role in people's lives. As a result, more and more smart home devices are appearing in people's lives. To this day, people are increasingly using cleaning robots in their lives, and fully automatic cleaning robots have gradually become a daily smart home device. To meet the growing demand for people's living standards, cleaning robots are now generally equipped with cleaning base stations. The cleaning base station and the cleaning robot form a cleaning robot system. Existing cleaning base stations generally have a water tank for storing clean water. The liquid supply structure and liquid injection device are used to perform maintenance work to replenish the cleaning robot's liquid storage tank so that the cleaning robot can carry out the next cleaning operation.

[0056] However, the liquid injection device of the existing cleaning base station generally adopts a gear rack transmission mechanism, which leads to problems such as a large number of parts, a complex structure, difficulty in installation, and high cost of use.

[0057] For the above technical issues, please refer to Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 as well as Figure 11 , the present application proposes a liquid injection device 100 for cleaning the base station 300. In an embodiment of the present application, the liquid injection device 100 includes a liquid injection part 110 and a driving assembly 120, wherein the liquid injection part 110 is used to communicate with the liquid supply structure 310 to transport the cleaning liquid, and the liquid injection part 110 has a first position and a second position; the driving assembly 120 includes a main driving part 121 and a rotating part 122, the rotating part 122 is rotatably connected to the main driving part 121, and the rotating part 122 is provided with at least one arc-shaped driving groove 1221. The outer peripheral surface of the liquid injection part 110 is provided with a driving rod 111 corresponding to the arc-shaped driving groove 1221, and the driving rod 111 can slide in the arc-shaped driving groove 1221; when the main driving part 121 drives the rotating part 122 to rotate, the arc-shaped driving groove 1221 pushes the driving rod 111 to drive the liquid injection part 110 to move back and forth between the first position and the second position.

[0058] In this embodiment, the cleaning base station 300 includes a liquid supply structure 310, and the liquid injection member 110 can be used to communicate with the liquid supply structure 310. For example, the liquid supply structure 310 can be a water tank (not shown in the figure) of the cleaning base station 300. Figure 11 As shown, when the liquid injection component 110 is installed on the cleaning base station 300, the liquid inlet 1121 of the liquid injection component 110 can be connected to the water tank of the cleaning base station 300. For example, the liquid injection component 110 can be connected to the water tank of the cleaning base station 300 via a connecting hose or other structure, but is not limited to this. The liquid injection component 110 can also be connected to different water tanks of the cleaning base station 300 via a three-way pipe or a four-way pipe to achieve multiple liquid supply functions. The liquid in the water tank of the cleaning base station 300 can be clean water or a liquid with a detergent added, depending on the specific situation.

[0059] In addition, it should be noted that the liquid supply structure 310 connected to the liquid injection part 110 mentioned in this embodiment is not limited to the water tank of the cleaning base station 300, but can also be an external tap water pipe or other structure, depending on the specific situation.

[0060] refer to Figure 4 and Figure 5 As shown, the liquid injection member 110 has a first position and a second position. The first position is a retracted state of the liquid injection member 110, which is stored in the cleaning base station 300. The second position is an extended state of the liquid injection member 110, and after the cleaning base station 300 is extended, it is the position for liquid injection of the cleaning robot 200. The drive assembly 120 is used to drive the liquid injection member 110 to move between the first position and the second position, so that the liquid injection member 110 extends into or out of the liquid storage tank 230 of the cleaning robot 200.

[0061] Specifically, the drive assembly 120 includes a main drive member 121 and a rotating member 122. The main drive member 121 is a power rotating component, such as a motor; the rotating member 122 is a rotating component that rotates through the rotation of the main drive member 121, such as a crank structure. The rotation of the main drive member 121 drives the rotating member 122 to rotate, which in turn drives the injection member 110 to move, thereby realizing the transmission and movement of the system within the injection device 100.

[0062] In this embodiment, at least one arc-shaped driving groove 1221 is provided on the rotating member 122. The shape of the arc-shaped driving groove 1221 includes, but is not limited to, one or more combinations of circular arcs, elliptical arcs, and parabolic arcs, which are not specifically limited here. The driving rod 111 of the injection member 110 can slide in the arc-shaped driving groove 1221. When the main driving member 121 drives the rotating member 122 to rotate, the driving rod 111 is squeezed and moved by the groove wall of the arc-shaped driving groove 1221, so that the driving rod 111 slides along the extension direction of the arc-shaped driving groove 1221. For example, the groove wall of the arc-shaped driving groove 1221 includes an inner wall and an outer wall (not shown in the figure). When the injection member 110 is in the first position, the driving rod 111 is at one end of the arc-shaped driving groove 1221, and the rotating member 122 can rotate counterclockwise around the main driving member 121. At this time, the inner wall of the arc-shaped driving groove 1221 abuts against the surface of the driving rod 111 to generate a push. The force causes the driving rod 111 to slide in the arc-shaped driving groove 1221 while pushing the injection piece 110 toward the second position; similarly, when the injection piece 110 is in the second position, the driving rod 111 is at the other end of the arc-shaped driving groove 1221, and the rotating piece 122 rotates clockwise around the main driving piece 121. At this time, the outer wall of the arc-shaped driving groove 1221 abuts against the surface of the driving rod 111 and moves to generate a reverse thrust, causing the driving rod 111 to slide back along the arc-shaped driving groove 1221 while pushing the injection piece 110 toward the first position; the above steps are repeated over and over again, thereby realizing the reciprocating motion of the injection piece 110 between the first position and the second position. Since the groove wall of the arc-shaped driving groove 1221 is a continuous curved shape, it can perfectly match the driving rod 111 of the injection part 110, not only providing better positioning accuracy and load-bearing capacity for the movement of the injection part 110, but also making the injection part 110 have higher matching and smoothness, making the transmission of the injection part 110 more stable, reducing the noise and vibration caused by unstable transmission, thereby improving the shock resistance of the injection device 100.

[0063] Compared with the traditional structure, the technical solution of the present application has the advantage of reducing the number of parts and simplifying the transmission system because the transmission mechanism inside the liquid injection device 100 is only provided with a rotating part 122, thereby achieving the advantages of compact internal structure and small space occupation, saving manufacturing cost and maintenance cost; in addition, the curved motion of the driving rod 111 in the arc-shaped driving groove 1221 is converted into the motion design of the displacement of the liquid injection part 110, so that the driving rod 111 slides in the groove and the transmission distance is small, which can achieve higher positioning accuracy and motion accuracy, thereby improving the reliability and stability of the equipment.

[0064] In some embodiments, please refer to Figure 4 、 Figure 5 and Figure 7In order to ensure the effect of the arc-shaped driving groove 1221 on the driving rod 111, the arc-shaped driving groove 1221 is an involute groove, the rotating member 122 includes a rotating end 1222 rotating around the main driving member 121, and the arc-shaped driving groove 1221 includes a starting end 12211 and an ending end 12212. The starting end 12211 is arranged on a side close to the rotating end 1222, and the ending end 12212 is arranged on a side away from the rotating end 1222; when the driving rod 111 is located at the starting end 12211, the liquid injection part 110 is in the first position, and when the driving rod 111 is located at the ending end 12212, the liquid injection part 110 is in the second position. When the arc-shaped driving groove 1221 adopts an involute groove, the tangential speed of the driving rod 111 sliding in the groove can be gradually increased or slowed down; for example, when the injection part 110 moves from the first position toward the second position, the moving speed of the injection part 110 continues to accelerate and can generate greater force, thereby improving the efficiency and quality of injection; when the injection part 110 moves from the second position back to the first position, the moving speed of the injection part 110 gradually slows down, thereby returning to the cleaning base station 300 in a stable state; in this way, the moving speed of the injection part 110 is controlled by the design of the involute groove, thereby improving the conversion efficiency of the device.

[0065] Furthermore, during the rotation of the rotating member 122, the liquid injection member 110 performs linear motion between the first position and the second position. The rotating end 1222 is defined as point O, the starting end 12211 is defined as point A, and the ending end 12212 is defined as point B. The liquid injection member 110 satisfies the following relationship:

[0066] L=OB-OA

[0067] Wherein, L is the straight-line distance between the first position and the second position, OA is the straight-line distance between the rotating end 1222 and the starting end 12211 , and OB is the straight-line distance between the rotating end 1222 and the ending end 12212 .

[0068] In some embodiments, please refer to Figure 7 The rotating member 122 is also provided with reinforcing ribs 1223, which extend radially from the rotating end 1222 toward the arc-shaped driving groove 1221; this not only increases the structural rigidity of the rotating member 122, but also facilitates the demolding of the arc-shaped driving groove 1221 and reduces structural deformation or vibration; it can also enhance the use strength of the arc-shaped driving groove 1221, improve the durability and reliability of the overall structure, and thus extend the service life of the rotating member 122.

[0069] In some embodiments, please refer to Figure 2 and Figure 3The main driving member 121 includes a driving motor 1211 and a mounting seat 1212. The driving motor 1211 is installed on one side of the mounting seat 1212, and the rotating member 122 is installed on the other side of the mounting seat 1212 away from the driving motor 1211. The output end of the driving motor 1211 is transmission-connected with the rotating member 122; the mounting seat 1212 is provided with a limiting slot 12121, and the limiting slot 12121 is arranged through the mounting seat 1212. The rotating member 122 is provided with a limiting column 1224 corresponding to the limiting slot 12121. The limiting column 1224 is limitedly installed in the limiting slot 12121, and the limiting column 1224 can slide in the limiting slot 12121.

[0070] Specifically, the mounting seat 1212 is provided with a limiting groove 12121 corresponding to the motion trajectory of the rotating member 122. Preferably, the limiting groove 12121 is also arranged in an arc shape, and the limiting post 1224 of the rotating member 122 is limitedly mounted in the limiting groove 12121. In this way, the limiting groove 12121 can limit the limiting post 1224 in the horizontal direction of the mounting seat 1212, limiting the rotation range of the rotating member 122, preventing it from excessive movement, and ensuring the motion accuracy of the main driving member 121. In addition, the limiting post 1224 is installed in the limiting groove 12121 in an embedded manner, which also limits the vertical position of the rotating member 122 along the mounting seat 1212, preventing the rotating member 122 from tilting and separating from the mounting seat 1212 during rotation, thereby affecting the normal use of the rotating member 122, and protecting the safety and stability of the liquid injection device 100.

[0071] For further information, please refer to Figure 2 and Figure 8 The end of the limiting post 1224 away from the rotating member 122 has an introduction slope 12241. The introduction slope 12241 extends from the top of the locking protrusion to the bottom in the direction of extension from the middle of the limiting post 1224 to the edge. The end of the limiting post 1224 close to the rotating member 122 is recessed toward the middle to form a groove 12241. The groove 12241 is adapted to be locked in the limiting groove 12121. Guided by the introduction slope 12241, the limiting post 1224 can more easily enter the limiting groove 12121. Then, the groove 12241 of the limiting post 1224 engages with the limiting groove 12121 to limit the movement of the limiting post 1224 within a certain range, thereby improving the accuracy and efficiency of assembly.

[0072] Furthermore, in order to improve the use effect of the limiting column 1224, the limiting column 1224 includes a first elastic portion 12243 and a second elastic portion 12244. The first elastic portion 12243 and the second elastic portion 12244 are spaced apart on the side of the rotating member 122 facing the limiting groove 12121. The first elastic portion 12243 and the second elastic portion 12244 form an introduction slope 12241 at one end away from the rotating member 122, and the first elastic portion 12243 and the second elastic portion 12244 form a groove 12241 at one end close to the rotating member 122; when the first elastic portion 12243 and the second elastic portion 12244 are elastically deformed by compression, the first elastic portion 12243 and the second elastic portion 12244 are suitable for passing through the limiting groove 12121, and when the first elastic portion 12243 and the second elastic portion 12244 return to their original state, the groove 12241 is suitable for being clamped in the limiting groove 12121. In this embodiment, the first elastic part 12243 and the second elastic part 12244 can be made of highly elastic material, which has the advantage that, on the one hand, it facilitates the installation of the limiting column 1224 in the limiting groove 12121, and on the other hand, when the limiting column 1224 vibrates relative to the limiting groove 12121, the deformation between the first elastic part 12243 and the second elastic part 12244 can be used to absorb the energy caused by collision or other impact, so that the rotating part 122 is not easily damaged and the service life is extended.

[0073] In some embodiments, please refer to Figure 5 and Figure 6 The main driving member 121 also includes a first sensing module 1213, which is arranged on the mounting seat 1212 and close to one end of the limiting groove 12121. The rotating member 122 is provided with a first triggering portion 1225, and the first triggering portion 1225 moves back and forth with the rotation of the rotating member 122. When the first triggering portion 1225 abuts against the first sensing module 1213, the injection member 110 stops at the second position; and / or the main driving member 121 also includes a second sensing module 1214, which is arranged on the mounting seat 1212 and close to the other end of the limiting groove 12121. The rotating member 122 is also provided with a second triggering portion 1226, which moves back and forth with the rotation of the rotating member 122. When the second triggering portion 1226 abuts against the second sensing module 1214, the injection member 110 stops at the first position.

[0074] Specifically, in one embodiment, the main driving member 121 is only provided with a first sensing module 1213. In actual application, the cleaning base station 300 may also be provided with a main control circuit. The first sensing module 1213 and the drive motor 1211 are respectively electrically connected to the main control circuit. When the first triggering portion 1225 abuts against the first sensing module 1213, the first sensing module 1213 sends a sensing signal to the main control circuit. The main control circuit sends a position instruction to the drive motor 1211 based on the signal, causing the rotating member 122 to stop rotating. At this time, the liquid injection member 110 just stops at the second position, that is, the liquid injection position of the liquid injection member 110 on the cleaning base station 300. At the same time, a liquid replenishment instruction is sent to the liquid supply structure 310 to supply cleaning liquid to the liquid injection member 110. Therefore, the provision of the first sensing module 1213 enables the liquid injection member 110 to efficiently and accurately dock with the cleaning robot 200 when the cleaning robot 200 is used in conjunction with the liquid injection device 100 in the cleaning base station 300. Furthermore, the drive motor 1211 is a stepper motor. When the liquid injection member 110 is to be retracted from the second position to the first position, the number of revolutions of the stepper motor is set, thereby driving the rotating member 122 to rotate a set angle, thereby driving the liquid injection member 110 to return to the first position, that is, the storage position of the liquid injection member 110 in the cleaning base station 300. This can reduce design costs. Of course, in another embodiment, the main drive member 121 is also provided with a first sensing module 1213 and a second sensing module 1214. The first sensing module 1213, the second sensing module 1214 and the drive motor 1211 are respectively electrically connected to the main control circuit. The first sensing module 1213 operates in the same manner as described above. Similarly, when the second triggering portion 1226 abuts the second sensing module 1214, the second sensing module 1214 sends a sensing signal to the main control circuit. The main control circuit sends a position command to the drive motor 1211 based on the signal, causing the rotating member 122 to stop rotating. At this time, the liquid injection member 110 just stops in the first position. Such a configuration can ensure the accuracy of the rotation angle of the rotating member 122 and realize the automatic contraction of the liquid injection member 110 without manual operation, thereby improving the automation of the cleaning base station 300 and enhancing the user experience.

[0075] In some embodiments, please refer to Figure 3 The main driving member 121 further includes a guide portion 1215, one end of which is connected to the mounting seat 1212. The rotating member 122 is disposed between the mounting seat 1212 and the guide portion 1215. The guide portion 1215 defines a guide hole 12151. The liquid injection member 110 is disposed within the guide hole 12151 and performs reciprocating linear motion along the axis of the guide hole 12151. The guide portion 1215 guides the movement of the liquid injection member 110, allowing it to move along a predetermined direction and trajectory, thereby ensuring the accuracy of the liquid injection member 110 when used in conjunction with the cleaning robot 200.

[0076] Furthermore, the longitudinal cross-sections of the guide hole 12151 and the injection member 110 are square, and the injection member 110 moves linearly downward along the guide hole 12151 at an inclined direction, with the angle between the movement direction of the injection member 110 and the horizontal plane being acute. In this embodiment, due to the square longitudinal cross-sections of the guide hole 12151 and the injection member 110, the injection member 110 cannot rotate and can only move linearly along the axis of the guide hole 12151. This prevents the injection member 110 from deviating from its track during movement and causing damage to the cleaning robot 200, thereby avoiding unnecessary losses and waste. In addition, since the liquid injection piece 110 is set downward, the liquid can flow naturally, and there will be no problems such as liquid backflow, slow flow rate, and easy liquid accumulation when flowing through the pipeline of the liquid injection piece 110, thereby improving the liquid circulation capacity and ensuring the continuous stability of the infusion; in addition, it can also prevent air, impurities and pollutants from entering the water tank through the liquid inlet 1121, prevent external microorganisms and other pollutants from entering, and ensure the hygiene and safety of the use of liquid in the water tank.

[0077] In some embodiments, please refer to Figures 9 to 11 The liquid injection member 110 includes a liquid injection tube 112 having a liquid inlet 1121 and a liquid outlet 1122 that are interconnected. The liquid inlet 1121 is used to communicate with the liquid supply structure 310. When the liquid injection tube 112 is installed in conjunction with the cleaning robot 200, the liquid outlet 1122 is used to dock with the liquid inlet 210 of the cleaning robot 200. The liquid injection tube 112 is also provided with an abutment top 1123 near the liquid outlet 1122. The abutment top 1123 is used to provide thrust to open the liquid inlet 210, thereby connecting the liquid injection tube 112 to the liquid storage tank 230 of the cleaning robot 200. In this embodiment, the liquid inlet 210 of the cleaning robot 200 is provided with an elastic sealing structure 220, which is used to seal the liquid inlet 210 in a normal state. When the top portion 1123 applies a certain force to the surface of the elastic sealing structure 220 , a thrust is generated, so that the elastic sealing structure 220 is pushed open, thereby opening the liquid inlet 210 and allowing the liquid in the injection tube 112 to flow into the liquid storage tank 230 .

[0078] Furthermore, the end of the top portion 1123 away from the liquid inlet 1121 has a guiding slope 11231, and the guiding slope 11231 extends from the liquid outlet 1122 toward the liquid inlet 1121 in the extension direction of the middle of the top portion 1123 to the edge. A plurality of spaced-apart diversion ports 11232 are also provided on the peripheral side of the top portion 1123 close to the guiding slope 11231, and the diversion ports 11232 are connected to the liquid outlet 1122. In this embodiment, the outer periphery of the liquid inlet 210 of the cleaning robot 200 is in the shape of a trumpet. When the top portion 1123 is docked with the liquid inlet 210, the guiding inclined surface 11231 contacts the outer periphery of the liquid inlet 210, guiding the cleaning robot 200 to continuously adjust its position so that the central axis position of the liquid injection tube 112 is aligned with the central axis position of the liquid inlet 210, thereby enabling the liquid injection tube 112 to accurately and quickly enter the interior of the liquid inlet 210; and the arrangement of the diversion port 11232, when the front end of the top portion 1123 contacts the elastic closing structure 220, the liquid can flow normally from the diversion port 11232, thereby ensuring the normal use of the liquid injection part 110; further, there are multiple diversion ports 11232, and the multiple diversion ports 11232 are arranged at equal intervals along the axial direction of the liquid injection tube 112, which can ensure the smooth flow of the liquid.

[0079] In some embodiments, please refer to Figure 9 The injection part 110 also includes a flexible sealing part 113. A fixing groove 1124 is provided on the peripheral side of the injection tube 112 near one end of the liquid outlet 1122. The flexible sealing part 113 is sleeved in the fixing groove 1124. The flexible sealing part 113 can be installed in conjunction with the cleaning robot 200 to ensure a sealed fit at the junction of the liquid outlet 1122 and the peripheral side of the liquid replenishing port 210; wherein, the outer surface of the flexible sealing part 113 has at least one circle of inclined barbs 1131, and the free end of the inclined barb 1131 is inclined from the liquid outlet 1122 toward the liquid inlet 1121.

[0080] For example, the flexible seal 113 may be a silicone seal ring, but is not limited thereto. It depends on the specific circumstances, as long as it can ensure good sealing performance while having a certain degree of deformation capability. The outer surface of the flexible seal 113 may have multiple circles of inclined barbs 1131, and adjacent inclined barbs 1131 are spaced apart in the fixed groove 1124. This facilitates the process of the liquid injection tube 112 docking with the liquid infusion port 210 of the cleaning robot 200. The inclined barbs 1131 and the movable margin are deformed, and an interference fit is formed at the connection with the peripheral side of the liquid infusion port 210. This ensures the sealing performance while preventing the liquid injection tube 112 from being recoiled from the liquid infusion port 210 due to hydraulic shock during the liquid infusion process.

[0081] In some embodiments, please refer to Figure 3The liquid injection member 110 further includes a positioning seat 114 having a positioning hole 1141 defined therein. The liquid injection tube 112 is installed within the positioning hole 1141. At least one clip 1142 is provided on a side of the positioning seat 114 away from the liquid outlet 1122. This clip 1142 is configured to engage with the base 320 of the cleaning base station 300. The positioning seat 114 facilitates the fixing and installation of the liquid injection member 110 on the cleaning base station, facilitating the use and replacement of the liquid injection member 110.

[0082] Please continue reading Figure 10 and Figure 11 The present application also proposes a cleaning base station 300, comprising a base 320 and the above-mentioned liquid injection device 100, wherein the liquid injection device 100 is installed on the base 320, wherein the base 320 has a docking position for the cleaning robot 200 to dock; the liquid injection device 100 can be connected with the cleaning robot 200 when the cleaning robot 200 is piled up to the docking position, so that the liquid injection part 110 is connected with the liquid storage tank 230 of the cleaning robot 200 when it is in the second position. In addition, the present application also proposes a cleaning system, comprising a cleaning robot 200 and the above-mentioned cleaning base station 300.
