Description

Technical Field

[0001] The invention relates to the technical field of sweeping machines, and in particular to a dust collection component and a base station for a cleaning robot. Background Art

[0002] At present, in the field of sweeping machines, the dust collection of sweeping machines and vacuum maintenance base stations is achieved by using dust boxes to collect dust. When using dust boxes to clean dust, it is difficult to completely clean pet hair and static dust through the dumping mode during the cleaning process. The filter components and dust boxes need to be washed or thoroughly cleaned every period of time, resulting in a lot of repetitive labor. Summary of the invention

[0003] In view of the above problems, the present invention provides a vacuuming component that can carry a detachable dust bag and supports manual triggering of opening and closing, making it very convenient to start vacuuming, place the dust bag, and take out the dust bag. The specific technical solution is as follows:

[0004] A dust suction assembly for a cleaning robot comprises a dust collecting chamber, the dust suction assembly comprises a mounting frame arranged inside the dust collecting chamber, a dust inlet above the dust collecting chamber is provided with a rotatable movable top cover, a dust inlet pipe is installed on the side of the mounting frame away from the dust inlet, a horizontal air duct is installed on the side of the mounting frame close to the dust inlet, and a dust bag is detachably installed on the side of the horizontal air duct close to the dust inlet, wherein the dust inlet pipe is connected to the horizontal air duct; a rotatable elastic opening and closing mechanism is installed on the side of the horizontal air duct away from the dust inlet, and a linkage mechanism is provided between the mounting frame and the movable top cover; the elastic opening and closing mechanism and the linkage mechanism cooperate with each other, so that a user can flip the movable top cover to press against the linkage mechanism, and then press to drive the elastic opening and closing mechanism to rotate in the horizontal air duct, so as to connect or block the horizontal air duct and the dust inlet pipe. Compared with the prior art, not only a low-cost dust collecting bag is used to replace the dust collecting box arranged inside the vacuum base station in the prior art, but also through the design of the movable top cover of the vacuum base station, the dust inlet pipe inside the vacuum base station, and the linkage and switch structure position between the dust bag inside the vacuum base station, the dust passage space between the movable top cover and the dust bag has the advantage of being easy to control according to the user's cleaning intention.

[0005] Furthermore, when the movable top cover covers the dust inlet, the movable top cover is used to abut the linkage mechanism to transmit the elastic force to press the elastic opening and closing mechanism, so that the horizontal air duct and the dust inlet pipe cooperate and penetrate to absorb the dust outside the dust collection assembly into the dust bag; when the movable top cover is separated from the dust inlet, the movable top cover is not used to abut the linkage mechanism, so that the linkage mechanism drives the elastic opening and closing mechanism to block the passage between the horizontal air duct and the dust inlet pipe by releasing the elastic force, so as to prevent the dust outside the dust collection assembly from being absorbed into the dust bag.

[0006] Further, the linkage mechanism includes a slot and a linkage rod, the linkage rod is slidably installed in the slot, the slot and the horizontal air duct have a connected portion, and the elastic opening and closing mechanism is rotatably installed at the connection position between the slot and the horizontal air duct, so that when the movable top cover covers the dust inlet, the linkage rod pushes the elastic opening and closing mechanism downward in the slot, or when the movable top cover is rotated to a preset position above the dust inlet, the linkage rod is pushed upward by the elastic opening and closing mechanism; wherein, a slot hole for the linkage rod to enter is formed between the slot and the horizontal air duct, so that the linkage rod can push the elastic opening and closing mechanism downward and then abut the elastic opening and closing mechanism, so that the horizontal air duct and the dust inlet pipe remain connected. Compared with the prior art, this technical solution uses a slot and a linkage rod that can slide in the slot to accept the closing and abutting action from the movable top cover, without the need for a motor control component to assist in completing this process, making it convenient for the user to operate, and the dust collection can be easily started by the action of covering the movable top cover.

[0007] Furthermore, the elastic opening and closing mechanism includes an elastic element, a movable rod, a pivot portion and a trigger rod, the movable rod and the trigger rod are rotatably mounted on the pivot portion at a fixed angle, the pivot portion is fixedly mounted at the connecting position of the slot and the horizontal air duct, and an elastic element is arranged on a side surface of the trigger rod corresponding to the slot hole for the linkage rod to enter, so that when the movable top cover covers the dust inlet, the elastic element is squeezed downward by the linkage rod to push the trigger rod and the movable rod to rotate until the movable rod contacts the inner surface of the horizontal air duct; or the elastic element also pushes the linkage rod to slide upward in the slot when the movable top cover is rotated to a preset position above the dust inlet, so as to drive the movable rod to rotate to block the passage between the horizontal air duct and the dust inlet pipe; wherein, the length of the movable rod is equal to the diameter of the horizontal air duct, the length of the movable rod is greater than the length of the trigger rod, and the fixed angle is between 75 degrees and 90 degrees. In this technical solution, the elastic opening and closing mechanism has a compact structure, which makes the connection and blocking of the horizontal air duct and the dust inlet pipe simple, is convenient for users to operate, and is also conducive to saving space.

[0008] Furthermore, the end of the dust inlet pipe away from the dust inlet is used to connect to the dust box of the cleaning robot, the end of the dust inlet pipe close to the dust inlet is connected to the end of the horizontal air duct away from the dust inlet, and the end of the horizontal air duct close to the dust inlet is detachably connected to the dust bag. This technical solution simplifies the dust inlet channel structure of the dust bag and also makes it convenient for users to take out the dust bag.

[0009] Furthermore, an air inlet is provided on the surface of the horizontal air duct, and the diameter of the air inlet is equal to the length of the movable rod, so that when the movable top cover covers the dust inlet, the movable rod covers the air inlet and the side of the air inlet stops against the movable rod, so that the channel between the horizontal air duct and the dust inlet pipe forms a sealed channel, thereby improving the reliability of the horizontal air duct and the dust inlet pipe.

[0010] Furthermore, the air inlet is used to vacuum the channel between the horizontal air duct and the dust inlet pipe and the dust bag through the cooperation of the dust suction fan, so that the dust and garbage in the dust box of the cleaning robot enters the dust bag through the corresponding channel, wherein the dust suction component also includes a dust suction fan. This technical solution guides the flow direction of the suction air through the air inlet, which makes it easier to connect the horizontal air duct and the dust inlet pipe, and can reduce the complexity of the main body of the dust suction component and reduce the manufacturing cost.

[0011] Furthermore, the slot is provided with a limiter, which is used to limit the trigger rod so as to limit the position of the linkage rod being pushed upward by the elastic element when the movable rod rotates to block the passage between the horizontal air duct and the dust inlet pipe, wherein the preset position above the dust inlet port is higher than the highest vertical position reached by the elastic element pushing the linkage rod upward. The linkage rod and the trigger rod disclosed in this technical solution are easier to control in terms of movement, and play a role in stopping the rotating component.

[0012] Furthermore, a protrusion structure is provided on one side of the movable top cover away from the dust inlet, which is used to buckle the movable top cover with the dust inlet to abut the linkage rod; wherein the preset position where the movable top cover is rotated to the top of the dust inlet refers to the vertical height position reached by the protrusion structure, thereby providing more sufficient force for the linkage rod, ensuring that the trigger rod and the movable rod are easier to swing.

[0013] A base station, the dust collection assembly for a cleaning robot is installed inside the base station. The dust collection can be easily and automatically triggered by manually closing the top cover, saving time and effort. When the dust is full, the dust bag can be directly taken out of the dust collection chamber of the sweeper and directly discarded in a trash can, avoiding secondary dust pollution caused by dumping the dust in the dust box, and effectively saving the labor of traditional water washing or deep cleaning of the dust box.

DETAILED DESCRIPTION

In addition, the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0020] The basic concept of a dust suction component for a cleaning robot disclosed in the present invention is that the dust suction component comprises a dust collecting chamber, a mounting frame arranged inside the dust collecting chamber, a rotatable movable top cover being arranged at the dust inlet above the dust collecting chamber, a dust inlet pipe being installed at a side of the mounting frame away from the dust inlet, a horizontal air duct being installed at a side of the mounting frame close to the dust inlet, and a dust bag being detachably installed at a side of the horizontal air duct close to the dust inlet, wherein the dust inlet pipe is connected to the horizontal air duct, but the dust inlet pipe and the horizontal air duct do not necessarily remain in a connected state; a rotatable elastic opening and closing mechanism is installed at the side of the horizontal air duct away from the dust inlet, and a linkage mechanism is arranged between the mounting frame and the movable top cover; the elastic opening and closing mechanism and the linkage mechanism cooperate with each other, so that a user can flip the movable top cover to press against the linkage mechanism, and then press to drive the elastic opening and closing mechanism to rotate in the horizontal air duct, so as to connect or block the horizontal air duct and the dust inlet pipe. Compared with the prior art, not only a low-cost dust collecting bag is used to replace the dust collecting box arranged inside the vacuum base station in the prior art, but also through the design of the movable top cover of the vacuum base station, the dust inlet pipe inside the vacuum base station, and the linkage and switch structure position between the dust bag inside the vacuum base station, the dust passage space between the movable top cover and the dust bag has the advantage of being easy to control according to the user's cleaning intention.

[0021] Combination Figure 1 and Figure 2 It can be seen that the embodiment of the present invention discloses a dust collection component for a cleaning robot. The dust collection component includes a dust collection chamber, but the dust collection component is not installed in the cleaning robot, so that the dust collection chamber is different from the dust collection box of the cleaning robot. The dust collection component includes a mounting frame (not shown in the figure) and a dust bag 111 arranged inside the dust collection chamber. A rotatable movable top cover 101 is arranged at the dust inlet above the dust collection chamber. When it is necessary to collect dust and garbage accumulated inside the dust collection box of the cleaning robot, the user only needs to manually press the movable top cover 101 to cover the dust inlet of the dust collection chamber ( Figure 1 When the dust bag inside the dust collection assembly needs to be sorted, the user only needs to manually open the movable top cover 101 that has been covered on the dust inlet of the dust collection chamber. A dust inlet pipe 110 is installed on the side of the mounting frame away from the dust inlet, corresponding to Figure 1 The end of the dust inlet pipe 110 away from the dust inlet is used to connect the dust box of the cleaning robot, providing a dust inlet channel for the dust box of the cleaning robot on the basis of ensuring sealing; a horizontal air duct 109 is installed on one side of the mounting frame close to the dust inlet, corresponding to Figure 1The dust inlet pipe 110 is connected to the end of the horizontal air duct 109 away from the dust inlet; the end of the horizontal air duct 109 close to the dust inlet is connected to the dust bag 111 in a detachable manner. The dust bag 111 is detachably installed on the side of the horizontal air duct 109 close to the dust inlet (the right side in the figure), which makes it easy to replace a new dust bag 111 in the dust collecting chamber; this embodiment simplifies the dust inlet channel structure of the dust bag 111, and also facilitates the user to take out the dust bag 111. A rotatable elastic opening and closing mechanism is installed on the side of the horizontal air duct 109 away from the dust inlet (the left side in the figure), which controls the opening and closing of the horizontal air duct 109 by rotating and covering. A linkage mechanism is provided between the mounting frame and the movable top cover 101. In this embodiment, the elastic opening and closing mechanism cooperates with the linkage mechanism, and the user flips the movable top cover 101 to press against the linkage mechanism, thereby pressing to drive the elastic opening and closing mechanism to rotate. This makes it convenient for the user to control the flow of dust into the dust bag 111. It should be noted that a dust suction motor is also provided on the mounting frame of the dust suction component, which is used to provide suction to the inside of the dust inlet pipe and the inside of the horizontal air duct or to pre-evacuate the dust inlet pipe, the horizontal air duct and the dust bag into a vacuum state, so as to absorb the garbage and dust in the dust box of the cleaning robot.

[0022] In one implementation, the movable top cover 101 covers the dust inlet to abut against the linkage mechanism to transmit elastic force to press the elastic opening and closing mechanism, so that the horizontal air duct 109 and the dust inlet pipe 110 cooperate to penetrate and absorb the dust outside the dust collection assembly into the dust bag 111. It should be noted that after the user flips the movable top cover 101 to cover the dust inlet, it keeps against the linkage mechanism and keeps the horizontal air duct 109 and the dust inlet pipe 110 connected.

[0023] In another implementation, the movable top cover 101 is separated from the dust inlet so that the linkage mechanism releases the elastic force to drive the elastic opening and closing mechanism to block the passage between the horizontal air duct 109 and the dust inlet pipe 110, so as to prevent the dust outside the dust collection assembly from being absorbed into the dust bag 111. It should be noted that after the movable top cover 101 is manually separated from the dust inlet by the user and is not covered together, the linkage mechanism loses the supporting force of the movable top cover 101, and the linkage mechanism is opened and closed under the elastic force of the elastic opening and closing mechanism. Figure 2 The status is reset back to Figure 1 At the same time, the elastic opening and closing mechanism also starts to reset back to Figure 1 state, and allow the horizontal air guide duct 109 and the dust inlet pipe 110 to enter and maintain a blocked state.

[0024] In the aforementioned embodiment, the mounting frame is designed to be an assembly bracket structure that cooperates with the horizontal air duct 109 and the dust inlet pipe 110, effectively supporting the horizontal air duct 109 and the dust inlet pipe 110 to be fixed in the dust collecting chamber, thereby bringing a better installation effect.

[0025] Combination Figure 1 and Figure 2 It can be seen that the linkage mechanism includes a slot 104 and a linkage rod 103. The linkage rod 103 can be slidably installed in the slot 104. There is a connecting portion between the slot 104 and the horizontal air duct 109. The elastic opening and closing mechanism is rotatably installed at the connecting position between the slot 104 and the horizontal air duct 109. The linkage rod 103 can also be detachably installed in the slot 104 and can be vertically inserted and moved in the slot 104 while maintaining contact and cooperation with the elastic opening and closing mechanism. Among them, when the movable top cover 101 covers the dust inlet, the linkage rod 103 pushes the elastic opening and closing mechanism downward in the slot 104, or when the movable top cover 101 loses the pressure to cover and rotates to a preset position above the dust inlet, the linkage rod 103 is pushed upward by the elastic opening and closing mechanism; preferably, a slot hole (not shown in the figure) for the linkage rod 103 to enter is formed between the slot 104 and the horizontal air duct 109, and the size of this slot hole is designed to allow the linkage rod 103 to push the elastic opening and closing mechanism downward and then press against the elastic opening and closing mechanism, so that the horizontal air duct 109 and the dust inlet pipe 110 remain connected. Compared with the prior art, the present embodiment uses a slot 104 and a linkage rod 103 that can slide in the slot 104 to accept the closing and abutting action from the movable top cover 101, and there is no need for a motor control component to control the up and down movement of the linkage rod 103. Instead, the movable top cover 101 is opened and closed by hand to assist in completing this process, making it convenient for users to operate. The present embodiment associates the opening and closing of the movable top cover 101 with the activity of the linkage mechanism, and it is easy to use the opening and closing of the movable top cover 101 to trigger the control of the action of the elastic opening and closing mechanism. The structure is simple and is conducive to reducing costs.

[0026] Combination Figure 1 and Figure 2It can be seen that the elastic opening and closing mechanism includes an elastic element 105, a movable rod 107, a pivoting portion 108 and a trigger rod 106. The movable rod 107 and the trigger rod 106 are rotatably mounted on the pivoting portion 108 at a fixed angle. The pivoting portion 108 is fixedly mounted at the connection position between the slot 104 and the horizontal air duct 109. The rotating shaft provided inside the pivoting portion 108 is installed at this connection position. The elastic element 105 is provided on a side of the trigger rod 106 corresponding to the slot hole for the linkage rod 103 to enter. In this embodiment, the length of the movable rod 107 is equal to the diameter of the horizontal air duct 109, the length of the movable rod 107 is greater than the length of the trigger rod 106, the angle between the movable rod 107 and the trigger rod 106 is between 75 degrees and 90 degrees, and the rotating shaft position of the pivoting portion 108 is the intersection position of the axis of the movable rod 107 and the axis of the trigger rod 106.

[0027] like Figure 2 As shown, the elastic element 105 is squeezed downward by the linkage rod 103 when the movable top cover 101 covers the dust inlet, so as to push the trigger rod 106 and the movable rod 107 to rotate around the axis where the pivot portion 108 is located, and the movable rod 107 is pushed to rotate clockwise around the pivot portion 108 until the movable rod 107 contacts the inner surface of the horizontal air duct 109. At this time, the linkage rod 103 stops the trigger rod 106 at the same position through the limiting effect of the elastic force of the elastic element 105, and the movable rod 107 also maintains contact with the inner surface above the horizontal air duct 109. Figure 2 As shown, at this time, the elastic element 105 is squeezed between the trigger rod 106 and the linkage rod 103. If the angle between the movable rod 107 and the trigger rod 106 is 90 degrees, the axis of the elastic element 105 is in the horizontal direction, and the axis of the trigger rod 106 is in the vertical direction. Then the dust bag 111 enters the dust suction state due to the cooperation and penetration of the horizontal air duct 109 and the dust inlet pipe 110.

[0028] like Figure 1 As shown, when the movable top cover 101 rotates to the preset position above the dust inlet, the linkage rod 103 loses the resisting force applied by the movable top cover 101, and the elastic element 105 loses the force applied by the linkage rod 103, and the elastic element 105 recovers from the squeezed state to the stretched state, thereby pushing the linkage rod 103 to slide upward in the slot 104, so as to drive the movable rod 107 to rotate counterclockwise around the pivot portion 108 to block the passage between the horizontal air duct 109 and the dust inlet pipe 110, wherein the upper surface of the trigger rod 106 becomes a slot hole facing the linkage rod 103, that is, the axis of the linkage rod 103 is perpendicular to the axis of the trigger rod 106.

[0029] In summary, the elastic opening and closing mechanism has a compact structure, which makes the connection and blocking of the horizontal air duct and the dust inlet pipe simple, is convenient for users to operate, and is also conducive to saving space.

[0030] It is worth noting that the end of the dust inlet pipe 110 away from the dust inlet is used to connect to the dust box of the cleaning robot (not shown in the figure), the end of the dust inlet pipe 110 close to the dust inlet is connected to the end of the horizontal air duct 109 away from the dust inlet, and the end of the horizontal air duct 109 close to the dust inlet is detachably connected to the dust bag 111. Compared with the prior art, the number of components inside the dust collection assembly is small and the structure is compact, which simplifies the dust inlet channel structure of the dust bag and also facilitates users to take out and replace the dust bag.

[0031] As an implementation method, combined with Figure 1 and Figure 2 It can be seen that the surface of the horizontal air guide duct 109 is provided with an air inlet corresponding to Figure 1 The opening position of the upper surface of the horizontal air guide duct 109; Figure 1 The diameter of the air inlet is equal to the length of the movable rod 107. Figure 2 As shown in the position of the movable rod 107 rotation, when the movable top cover 101 covers the dust inlet, the movable rod 107 covers the air inlet and the side of the air inlet stops against the movable rod 107. At this time, regardless of whether the angle between the movable rod 107 and the trigger rod 106 is 90 degrees, under the downward squeezing action of the linkage rod 103, the elastic element 105 can push the movable rod 107 to rotate clockwise around the pivot 108 until the movable rod 107 stops against the side of the air inlet and maintains this stop position. At this time, the elastic element 105 is clamped between the trigger rod 106 and the linkage rod 103 by the limiting effect of the elastic force, not necessarily on the horizontal plane but must maintain a fixed position, so that the channel between the horizontal air duct and the dust inlet pipe forms a sealed channel. Improve the reliability of the horizontal air duct 109 and the dust inlet pipe 110.

[0032] Preferably, the air inlet is also used to evacuate the channel between the horizontal air duct 109 and the dust inlet pipe 110 and the dust bag 111 through the cooperation of the dust suction fan provided inside the dust suction assembly before the movable top cover 101 does not cover the dust inlet or when the movable rod 107 does not stop at the side of the air inlet, so that the dust and garbage in the dust box of the cleaning robot enter the dust bag through the corresponding channel, wherein the dust suction fan can be installed in the fan chamber in the dust collecting chamber or on the mounting frame, which is conducive to guiding the flow direction of the suction air of the dust inlet pipe 110 through the air inlet, making it easier to connect the horizontal air duct and the dust inlet pipe, and can reduce the complexity of the main body of the dust suction assembly and reduce the manufacturing cost. If a fan chamber is provided in the dust collecting chamber, a corresponding air duct and exhaust port connected to the air inlet are designed.

[0033] Preferably, the slot 104 is provided with a limiter, which is used to limit the trigger rod 106 when the movable rod 107 rotates to block the passage between the horizontal air duct 109 and the dust inlet pipe 110, so as to limit the position of the linkage rod 103 being pushed upward by the elastic element 105, and prevent the linkage rod 103 from being disengaged from the slot 104, wherein the preset position above the dust inlet port is higher than the highest vertical position reached by the elastic element 105 pushing the linkage rod 103 upward. Figure 1 and Figure 2 The illustrated embodiment allows for easier control of movement and serves as a stop for the rotating component.

[0034] On the basis of the above-mentioned embodiment, a protruding structure 102 is provided on the side of the movable top cover 101 away from the dust inlet, which is used for the movable top cover 101 to cover the dust inlet and abut the linkage rod 103; preferably, when the movable top cover 101 covers the dust inlet, the protruding structure 102 is engaged with the buckle part provided inside the dust inlet, so that after the user flips the movable top cover 101 to cover the dust inlet, it keeps abutting the linkage mechanism and keeps the horizontal air duct 109 and the dust inlet pipe 110 in a connected state. Among them, the preset position where the movable top cover 101 rotates to the top of the dust inlet refers to the vertical height position reached by the protruding structure 103, such as Figure 1 As shown, more sufficient force is provided to the linkage rod 103, ensuring that the trigger rod 106 together with the movable rod 107 can swing more easily.

[0035] Preferably, a sterilizing device and a container detection member are installed on one side of the horizontal air duct 109 close to the dust inlet. The sterilizing device is used to sterilize the dust and garbage entering the dust bag, and the container detection member is used to detect whether the dust bag is installed in the horizontal air duct 109. When the movable rod 107 is rotated to block the passage between the horizontal air duct 109 and the dust inlet pipe 110, the mounting frame triggers the detection switch to detect whether the dust bag 111 is installed. The sterilizing device can be a sterilizing lamp or a negative ion generator, which can effectively prevent the dust in the dust bag from generating odor after being left for a long time, thereby bringing better antibacterial effect.

[0036] In some embodiments, the dust bag 111 made of flexible material includes an opening portion and a containing portion, the opening portion is connected to a channel opening at one end of the horizontal air duct 109 close to the dust inlet, and the shape and size of the opening portion are adapted to the shape and size of the channel opening, after the dust and garbage in the dust box of the cleaning robot enters the dust bag 111 through the horizontal air duct 109, the spatial volume of the containing portion changes within a preset range.

[0037] A base station, in which the dust collection assembly for a cleaning robot of the aforementioned embodiment is installed. The dust collection can be easily and automatically triggered by manually closing the top cover, saving time and effort. When the dust is full, the dust bag can be directly taken out of the dust collection chamber of the sweeper and directly discarded in a trash can, avoiding secondary dust pollution caused by dumping the dust in the dust box, and effectively saving the labor of traditional water washing or deep cleaning of the dust box.
