With the continuous development of technology, smart home devices play an increasingly important role in people's lives, and as a result, more and more smart home devices appear in people's lives. Until today, more and more cleaning robots are used in people's lives, and fully automatic cleaning robot has gradually become a daily smart home device. In order to meet the growing demand for people's living standards, cleaning robots have been commonly equipped with cleaning base stations, cleaning base stations and cleaning robots constitute a cleaning robot system. The existing cleaning base stations generally have a water tank for storing clean water, and the liquid supply structure and liquid injection device replenish liquid for the liquid storage tank of the cleaning robot, so that the cleaning robot carries out the next cleaning operation.
However, the liquid injection device of the existing cleaning base station generally adopts a gear and rack transmission mechanism, which leads to the problems of a large number of components, a complex structure, a difficult installation, and a high cost of use.
In view of the above existing technical problems, please refer to
In this embodiment, the cleaning base station 300 includes a liquid supply structure 310, and the liquid injection member 110 may be used to be in communication with the liquid supply structure 310. For example, the liquid supply structure 310 may be a water tank of the cleaning base station 300, that is, as shown in
In addition, it is also noted that the liquid supply structure 310 referred to in this embodiment and connected to the liquid injection member 110 is not limited to the water tank of the cleaning base station 300, but may also be a structure such as an external tap water pipe, which is determined as actual.
Referring to
Specifically, the driving assembly 120 includes a main driving member 121 and a rotation member 122, the main driving member 121 is a powered rotation member, such as a motor. The rotation member 122, such as a crank structure, rotates by the rotation of the main driving member 121. The rotation member 122 is driven to rotate by the rotation of the main driving member 121, which in turn drives the liquid injection member 110 to rotate, thereby enabling the transmission and movement of the system within the liquid injection device 100.
In this embodiment, the rotation member 122 is provided with at least one arc driving groove 1221, and a shape of the arc driving groove 1221 includes, but is not limited to, one or a combination of circular arcs, elliptical arcs, and parabolic arcs, which is not specifically limited herein. The driving rod 111 of the liquid injection member 110 can slide within the arc driving groove 1221. When the main driving member 121 drives the rotation member 122 to rotate, the driving rod 111 is squeezed by a groove wall of the arc driving groove 1221 to move, so that the driving rod 111 slides along the extension direction of the arc driving groove 1221. For example, the groove wall of the arc driving groove 1221 includes an inner wall and an outer wall (not shown in the figure), and when the liquid injection member 110 is located in the first position, the driving rod 111 is located at one end of the arc driving groove 1221, and the rotation member 122 can rotate counterclockwise around the main driving member 121, and at this time, the inner wall of the arc driving groove 1221 resists against the surface of the driving rod 111 to move to generate a thrust force, so that when the driving rod 111 slides in the arc driving groove 1221, it pushes the liquid injection member 110 to move towards the second position. Similarly, when the liquid injection member 110 is located in the second position, the driving rod 111 is located at another end of the arc driving groove 1221, and the rotation member 122 rotates clockwise around the main driving member 121, and at this time, the outer wall of the arc driving groove 1221 resists against the surface of the driving rod 111 to move to generate a reverse thrust, so that when the driving rod 111 slides back along the arc driving groove 1221, it pushes the liquid injection member 110 to move toward the first position. The above steps are alternated repeatedly to achieve reciprocal movement of the liquid injection member 110 between the first position and the second position. Since a shape of the groove wall of the arc driving groove 1221 is a continuous curve, it can be perfectly fit with the driving rod 111 of the liquid injection member 110, which not only provides better positioning precision and load-bearing capacity for the movement of the liquid injection member 110, but also provides the liquid injection member 110 with a high degree of compatibility and smoothness, such that the transmission of the liquid injection member 110 is smoother, and noise and vibration caused by the unsmooth transmission are reduced, thereby improving the vibration resistance of the liquid injection device 100.
The technical solution of the present application, compared with the traditional structure, since the transmission mechanism inside the liquid injection device 100 is provided with only one component, that is, the rotation member 122, such that the number of components is reduced, the transmission system is simplified, the advantages of a compact internal structure and a small occupied space are achieved, and the manufacturing cost and the maintenance cost are reduced. In addition, the curved motion done by the driving rod 111 in the arc driving groove 1221 is converted into the displacement of the liquid injection member 110, such motion design makes the driving rod 111 slide in the arc driving groove and the transmission distance is small, which can achieve high positioning precision and motion accuracy, thus improving the reliability and stability of the equipment.

Further, during the rotation of the rotation member 122, the liquid injection member 110 moves in a straight line between the first position and the second position, the rotation end 1222 is defined as point O, the start end 12211 is defined as point A, and the ending end 12212 is defined as point B, and the liquid injection member 110 satisfies the following relational equation:
L=OB−OA

Specifically, the mounting seat 1212 is provided with the limitation groove 12121 corresponding to a movement trajectory of the rotation member 122. Preferably, the limitation groove 12121 also has a curved shape, and the limitation column 1224 of the rotation member 122 is restrictedly mounted in the limitation groove 12121. In this way, the limitation groove 12121 can limit the limitation column 1224 along a horizontal direction of the mounting seat 1212, limiting a rotation range of the rotation member 122, thereby preventing its excessive movement, and ensuring the movement precision of the main driving member 121. Furthermore, the limitation column 1224 is embedded into the limitation groove 12121, which also limits the rotation member 122 along a vertical direction of the mounting seat 1212, thereby preventing the rotation member 122 from being tipped up and detaching from the mounting seat 1212 during rotation, which affects the normal use of the rotation member 122, such that the safety and stability of the use of the liquid injection device 100 is protected.
Further, please continue to refer to
Further, in order to improve the effect of using the limitation column 1224, the limitation 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 a side of the rotation member 122 that faces the limitation groove 12121, and the introduction slope 12241 is formed on a side of the first elastic portion 12243 and the second elastic portion 12244 away from the rotation member 122. The recess 12242 is formed on a side of the first elastic portion 12243 and the second elastic portion 12244 towards the rotation member 122. The first elastic portion 12243 and second elastic portion 12244 are passed through the limitation grooves 12121 when the first elastic portion 12243 and second elastic portion 12244 are subjected to elastic deformation by compression, and the recess 12242 is buckled into the limitation groove 12121 when the first elastic portion 12243 and second elastic portion 12244 are restored to their original states. In this embodiment, the first elastic portion 12243 and the second elastic portion 12244 may be made of a highly elastic material, which is advantageous in that, on the one hand, it is convenient for the installation of the limitation column 1224 in the limitation groove 12121, and on the other hand, in the event of a vibration of the limitation column 1224 relative to the limitation groove 12121, a deformation between the first elastic portion 12243 and the second elastic portion 12244 may be used to absorb the energy caused by a collision or other impact, so that the rotation member 122 is not susceptible to damage and the service life is extended.

Specifically, in one of the implementations, the main driving member 121 is only provided with the first sensing module 1213. In practical application, the cleaning base station 300 can also be provided with a main control circuit, the first sensing module 1213 and the driving motor 1211 are electrically connected to the main control circuit. When the first triggering portion 1225 touches the first sensing module 1213, the first sensing module 1213 sends a sensing signal to the main control circuit, and the main control circuit sends a position instruction to the driving motor 1211 based on the sensing signal, so that the rotation member 122 stops 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, and sends a replenishment instruction to the liquid supply structure 310, so as to deliver cleaning liquid to the liquid injection member 110. As a result, since the first sensing module 1213 is provided, the liquid injection device 100 can efficiently and accurately dock with the cleaning robot 200 when the cleaning robot 200 cooperates with the liquid injection device 100 within the cleaning base station 300. Further, the driving motor 1211 is a stepping motor, so that when the liquid injection member 110 needs to be retracted from the second position to the first position, by setting the number of rotations of the stepping motor, the rotation member 122 is driven to rotate at a set angle, thereby driving the liquid injection member 110 to return to the first position, that is, the liquid injection member 110 is located at the accommodation position of the cleaning base station 300, which can reduce the design cost. Of course, in another embodiment, the main driving member 121 is provided with the first sensing module 1213 and the second sensing module 1214. The first sensing module 1213, the second sensing module 1214, and the driving motor 1211 are electrically connected to the main control circuit, respectively. The first sensing module 1213 may operates in the same steps as described above. Similarly, when the second triggering portion 1226 touches the second sensing module 1214, the second sensing module 1214 sends a sensing signal to the main control circuit, and the main control circuit sends a position instruction to the driving motor 1211 based on the sensing signal, so that the rotation member 122 stops rotating, and at this time, the liquid injection member 110 just stops at the first position. With such setting, the precision of the rotation angle of the rotation member 122 can be ensured, and the automatic contraction of the liquid injection member 110 can be achieved without manual operation, which improves the automation of the cleaning base station 300 and the user's experience.

Further, longitudinal cross sections of the guiding hole 12151 and the liquid injection member 110 are square, the liquid injection member 110 moves downwards obliquely in the straight line along the guiding hole 12151, and an acute angle is formed between a movement direction of the liquid injection member 110 and a horizontal plane. In this embodiment, since longitudinal cross sections of the guiding hole 12151 and the liquid injection member 110 are square, the liquid injection member 110 cannot perform rotational movement, but can only perform linear movement along the axis of the guiding hole 12151, preventing the liquid injection member 110 from deviating from the track during movement, to damage the cleaning robot 200, and avoiding unnecessary loss and waste. In addition, because the liquid injection member 110 is provided downward, the liquid can flow naturally, and there will be no problems such as backing up, slow flow rate, easy accumulation of liquid, etc., when flowing through the pipeline of the liquid injection member 110, so as to improve the circulation capacity of the liquid, and to ensure the continuous stability of delivering liquid. Furthermore, it can also avoid the entry of air, impurities, and pollutants into the water tank through the inlet port 1121, and prevent the entry of pollutants, such as microorganisms, from the outside, so as to ensure the hygienic and safe use of the liquid in the water tank.

Further, one end of the resisting top portion 1123 away from the inlet port 1121 has a guiding slope 11231, the guiding slope 11231 is extended from the outlet port 1122 towards the inlet port 1121 in a direction from a middle of the resisting top portion 1123 towards an edge of the resisting top portion 1123, and a number of spaced diversion ports 11232 are also provided on a periphery of the resisting top portion 1123 close to the guiding slope 11231, and each diversion port 11232 is communicated with the outlet port 1122. In this embodiment, the outer peripheral edge of the liquid replenishment port 210 of the cleaning robot 200 is in a shape of a flared mouth. When the resisting top portion 1123 is docked with the liquid replenishment port 210, and the guiding slope 11231 is in contact with the outer peripheral edge of the liquid replenishment port 210, the cleaning robot 200 is guided to continuously adjust the position, so as to align the position of a middle axis of the liquid injection tube 112 with the position of a middle axis of the liquid replenishment port 210, thereby realizing that the liquid injection tube 112 accurately and quickly enters into an interior of the liquid replenishment port 210. Since the diversion port 11232 is provided, so that when a front end of the resisting top portion 1123 contacts the elastic closure structure 220, the liquid can normally flow through from the diversion port 11232, thereby ensuring the normal use of the liquid injection member 110. Further, there are a plurality of diversion ports 11232, and the plurality of diversion ports 11232 are provided at equal intervals in the axial direction of the liquid injection tube 112, so as to ensure smoothness when the liquid flows.

By way of example, the flexible sealing member 113 may be a silicone seal, but is not limited to this, which is depending on the specific circumstances, as long as it can ensure a good sealing and have a certain deformation ability. The outer surface of the flexible sealing member 113 may have the plurality of inclined barbs 1131, and adjacent inclined barbs 1131 are spaced apart in the fixing groove 1124, so as to facilitate the docking process of the liquid replenishment port 210 with the liquid injection tube 112 of cleaning robot 200, the inclined barbs 1131 are deformed with the movable residual amount, and the inclined barbs 1131 are connected to the periphery of the liquid replenishment port 210 by an interference fit to ensure sealing performance, while preventing the liquid injection tube 112 from recoiling out of the liquid replenishment port 210 due to hydraulic impact during the liquid replenishment.
