Description

Technical Field

[0001] This utility model belongs to the field of sweeping robot technology, and more specifically, it relates to an automatic dust collection and recharging sweeping machine. Background Technology

[0002] As people's living standards improve, robotic vacuum cleaners, as smart home devices that effectively reduce housework, are gradually entering thousands of households. Robotic vacuum cleaners use their built-in cleaning components to collect debris from the floor, automating floor cleaning. The accompanying dust collection station sucks debris from the vacuum cleaner's dustbin into a large-capacity dust collection device, reducing the hassle of frequent dustbin emptying for users. The accompanying charging station allows the robotic vacuum cleaner to recharge when its battery is depleted. Therefore, robotic vacuum cleaners require relatively many accessories, resulting in higher operating costs.

[0003] Moreover, existing robot vacuum cleaners and dust collection station systems have significant shortcomings in actual use. Numerous users have reported that the dust collection station often fails to completely remove debris from the robot vacuum's dustbin. On one hand, the dust collection station's suction power is limited, making it difficult to thoroughly remove debris adhering to the dustbin walls, corners, and complex structures. On the other hand, the connection between the dust collection station and the robot vacuum's dustbin is poorly sealed, leading to air leakage during the debris extraction process, weakening the actual suction power and affecting the debris collection effect. Incomplete debris removal not only reduces the cleaning convenience of the robot vacuum and dust collection station but also allows residual debris to easily breed bacteria, posing a threat to indoor environmental health.

Detailed Implementation

[0028] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0032] As people's living standards improve, robotic vacuum cleaners, as smart home devices that effectively reduce housework, are gradually entering thousands of households. Robotic vacuum cleaners use their built-in cleaning components to collect debris from the floor, automating floor cleaning. The accompanying dust collection station sucks debris from the vacuum cleaner's dustbin into a large-capacity dust collection device, reducing the hassle of frequent dustbin emptying for users. The accompanying charging station allows the robotic vacuum cleaner to recharge when its battery is depleted. Therefore, robotic vacuum cleaners require relatively many accessories, resulting in higher operating costs.

[0033] Moreover, existing robot vacuum cleaners and dust collection station systems have significant shortcomings in actual use. Numerous users have reported that the dust collection station often fails to completely remove debris from the robot vacuum's dustbin. On one hand, the dust collection station's suction power is limited, making it difficult to thoroughly remove debris adhering to the dustbin walls, corners, and complex structures. On the other hand, the connection between the dust collection station and the robot vacuum's dustbin is poorly sealed, leading to air leakage during the debris extraction process, weakening the actual suction power and affecting the debris collection effect. Incomplete debris removal not only reduces the cleaning convenience of the robot vacuum and dust collection station but also allows residual debris to easily breed bacteria, posing a threat to indoor environmental health.

[0034] To alleviate or solve the above-mentioned technical problems, this utility model proposes an automatic dust collection and recharging sweeper, including a main unit 10 and a charging dust collection station 20. The charging dust collection station 20 has dust collection and charging functions. When the main unit 10 is connected to the charging dust collection station 20, it can not only collect the garbage in the main unit 10, but also charge the main unit 10, eliminating the need for separate dust collection and charging of the main unit 10, thus reducing the equipment required to support the main unit 10. Moreover, the bottom wall height of the garbage chamber 110 inside the main unit 10 gradually decreases in the dust collection direction, making it easier to suck garbage out of the garbage chamber 110.

[0035] The automatic dust collection and recharging sweeper provided in the embodiments of this utility model will now be described.

[0036] Please refer to the following: Figures 1 to 5 Automatic dust collection and recharging sweepers include:

[0037] The main unit 10 is used to move and collect garbage on the ground. The main unit 10 includes a first housing 11 and a first conductive structure 12 disposed on the first housing 11. The first housing 11 has a garbage chamber 110 for containing garbage. The garbage chamber 110 has a garbage inlet 111 and a garbage outlet 112. The garbage inlet 111 and the garbage outlet 112 are respectively provided with a first shielding structure 13 and a second shielding structure 14. The direction in which garbage flows out of the garbage chamber 110 is the dust collection direction. In the dust collection direction, the height of the bottom wall of the garbage chamber 110 gradually decreases.

[0038] The charging dust collection station 20 is used to charge the main unit 10 and collect the garbage in the garbage chamber 110. The charging dust collection station 20 includes a second housing 21 and a second conductive structure 22 disposed on the second housing 21. When the charging dust collection station 20 charges the main unit 10, the first conductive structure 12 and the second conductive structure 22 are in contact with each other and conduct electricity. The second housing 21 has a dust collection channel 211 and a dust collection chamber 210 that are interconnected. The end of the dust collection channel 211 away from the dust collection chamber 210 is the dust collection inlet 2110, which is used to be directly opposite the garbage outlet 112.

[0039] The main unit 10 is a self-moving mechanism capable of moving on the ground and cleaning it. Cleaned debris enters the debris chamber 110 through the debris inlet 111. The main unit 10 includes a first housing 11 and a first conductive structure 12 disposed on the first housing 11, with the debris chamber 110 located within it. Generally, the main unit 10 also includes a self-driving component, a cleaning component, a first air pump component, a battery, and a first circuit board. The self-driving component drives the main unit 10 to move on the ground, the cleaning component cleans the ground, the first air pump component provides negative pressure to draw debris from the ground into the debris chamber 110, and the battery is electrically connected to the first conductive structure 12. The debris chamber 110 is generally small in size; therefore, after a period of use, it fills with debris and needs to be cleaned. Furthermore, the battery power gradually decreases after a period of use, requiring the main unit 10 to be recharged.

[0040] The waste chamber 110 has a waste inlet 111 and a waste outlet 112. A first shielding structure 13 is used to shield the waste inlet 111, and a second shielding structure 14 is used to shield the waste outlet 112. The dust collection direction is the direction in which waste is sucked out from the waste outlet 112, which can also be understood as the horizontal direction. In the dust collection direction, the bottom wall height of the waste chamber 110 gradually decreases; that is, the bottom wall height of the waste chamber 110 gradually decreases from the direction away from the waste outlet 112 to the direction closer to the waste outlet 112. The bottom wall height of the waste chamber 110 is measured with reference to the main unit 10 being placed on a horizontal surface.

[0041] The charging dust collection station 20 can collect the waste in the waste chamber 110 of the main unit 10 and also charge the main unit 10. Specifically, the charging dust collection station 20 includes a second housing 21 and a second conductive structure 22 disposed on the second housing 21. The second housing 21 has a dust collection channel 211 and a dust collection chamber 210. The charging dust collection station 20 generally also includes a second circuit board, a power cord, a second air pump assembly, etc. The second conductive structure 22 is electrically connected to the circuit board, the circuit board is electrically connected to the power cord, the power cord can be connected to the mains power, and the second air pump assembly is used to provide negative pressure so that the waste in the waste chamber 110 is sucked into the dust collection chamber 210.

[0042] When the main unit 10 is working independently, the main unit 10 moves on the ground. At the same time, the cleaning component works and negative pressure is generated in the garbage chamber 110. The first shielding structure 13 is opened under the action of negative pressure, and garbage enters the garbage chamber 110 through the garbage inlet 111.

[0043] When the main unit 10 needs to clean the waste chamber 110, and / or when the main unit 10 needs to be charged, the main unit 10 moves to the charging dust collection station 20, and the first conductive structure 12 and the second conductive structure 22 come into contact with each other, thereby charging the main unit 10. At the same time, the dust collection inlet 2110 and the waste outlet 112 face each other, and a negative pressure is generated in the dust collection chamber 210, causing the second shielding structure 14 to open. Under the action of the negative pressure, the waste in the waste chamber 110 is gradually sucked into the dust collection chamber 210, thereby completing the cleaning of the waste chamber 110 of the main unit 10.

[0044] The automatic dust collection and recharging sweeper in the above embodiment includes a main unit 10 and a charging and dust collection station 20. The main unit 10 has a waste chamber 110 and a first conductive structure 12. The charging and dust collection station 20 has a dust collection chamber 210 and a second conductive structure 22. When the main unit 10 of the sweeper is connected to the charging and dust collection station 20, the first conductive structure 12 and the second conductive structure 22 are in contact with each other. The waste outlet 112 of the waste chamber 110 and the dust collection inlet 2110 of the dust collection channel 211 are directly opposite each other. This allows the main unit 10 to be charged simultaneously when the waste in the main unit 10 is sucked back for dust collection. Therefore, there is no need to configure a charging station and a dust collection station at the same time, resulting in lower operating costs for the sweeper. Moreover, the bottom wall height of the waste chamber 110 in the main unit 10 gradually decreases in the dust collection direction, making it easier for waste to enter the dust collection chamber 210 from the waste chamber 110 through the waste outlet 112 and the dust collection inlet 2110, and making it easier to clean the waste in the waste chamber 110.

[0045] Please refer to some embodiments of this utility model. Figure 3The bottom wall of the waste chamber 110 includes an arc-shaped wall 1101 and a horizontal wall 1102 that are smoothly connected to each other. The end of the arc-shaped wall 1101 away from the horizontal wall 1102 is higher than the horizontal wall 1102. The waste outlet 112 is located at the end of the horizontal wall 1102 away from the arc-shaped wall 1101. The end of the arc-shaped wall 1101 away from the horizontal wall 1102 is higher, and the end connected to the horizontal wall 1102 is lower. The horizontal wall 1102 can be understood as a horizontally positioned inner wall. Waste can slide along the arc-shaped wall 1101 and the horizontal wall 1102 to the waste outlet 112. Figure 3 The dust collection direction is from right to left, and the right end of the arc-shaped wall 1101 is higher than the left end of the arc-shaped wall 1101.

[0046] By designing the arc-shaped wall 1101, the height of the bottom wall of the waste chamber 110 gradually decreases in the dust collection direction. Waste can gradually slide down along the extension direction of the arc-shaped wall 1101 to the horizontal wall 1102, and then be discharged from the waste outlet 112. In this way, as waste is discharged from the inside of the waste chamber 110 through the waste outlet 112, there are no dead corners where waste gets stuck, and the waste can slide towards the waste outlet 112 under the action of gravity. This results in higher waste recycling efficiency for the main unit 10 and makes it less likely for waste to remain in the waste chamber 110.

[0047] Please refer to some embodiments of this utility model. Figure 3 The first housing 11 also includes a collection channel 113 for collecting garbage from the ground to the garbage chamber 110. One end of the collection channel 113 is close to the ground, and the other end of the collection channel 113 is connected to the arc-shaped wall 1101, so that the collection channel 113 and the garbage chamber 110 are in communication. The collection channel 113 and the garbage chamber 110 are interconnected. When garbage on the ground is swept to the vicinity of the collection channel 113, the garbage enters the collection channel 113 under negative pressure, and then enters the arc-shaped wall 1101 of the garbage chamber 110 through the garbage inlet 111. If there is little garbage in the garbage chamber 110, the garbage will slide along the arc-shaped wall 1101 to the horizontal wall 1102.

[0048] By setting up the collection channel 113, garbage on the ground can enter the garbage chamber 110 through the collection channel 113. After entering the garbage chamber 110, the garbage is less likely to fall back to the ground.

[0049] In some embodiments, the collection channel 113 has a long, narrow cross-section and is an inclined channel. The long, narrow structure of the collection channel 113 provides greater contact space with the ground, making it easier for piled-up garbage to enter. When the collection channel 113 is an inclined channel, the end of the collection channel 113 near the ground is lower, and the end near the curved wall 1101 is higher. This prevents garbage from falling back to the ground after entering the garbage chamber 110, and also makes it easier to pump garbage into the garbage chamber 110.

[0050] In other embodiments, the cross-section of the collection channel 113 is square, irregular in shape, etc.

[0051] In some embodiments, the first housing 11 has a guide rib on the side facing the ground. The guide rib is protruding and has a gradually widening V-shaped structure. The collection channel 113 is located at the smaller end of the guide rib. In this way, when the garbage is swept to the guide rib, as the main unit 10 moves, the garbage will be gradually guided and gathered into the collection channel 113, making it convenient for the collection channel 113 to suck up the garbage.

[0052] Please refer to some embodiments of this utility model. Figure 3 One side of the first shielding structure 13 is rotatably connected to the first housing 11. A first elastic member is provided between the first shielding structure 13 and the first housing 11. The first elastic member is used to make the other side of the first shielding structure 13 tightly adhere to the inner wall of the waste chamber 110. The first elastic member provides a certain pre-tightening force to the first shielding structure 13, making the first shielding structure 13 tightly adhere to the inner wall of the waste chamber 110. Specifically, when there is no external force, the side of the first shielding structure 13 away from its rotation axis is tightly adhered to the inner wall of the waste chamber 110, thereby sealing the waste inlet 111; when a negative pressure is generated in the waste chamber 110, the negative pressure causes the first shielding structure 13 to rotate relative to the first housing 11, the waste inlet 111 opens, and waste enters the waste chamber 110 through the waste inlet 111.

[0053] By setting the first elastic element, the first shielding structure 13 can block the garbage inlet 111 in its natural state; under the action of negative pressure, the second shielding structure 14 can be rotated and opened.

[0054] In some embodiments, the first elastic element is a torsion spring and is disposed at the rotatable connection between the first shielding structure 13 and the first housing 11.

[0055] Please refer to some embodiments of this utility model. Figure 3One side of the second shielding structure 14 is rotatably connected to the first housing 11. A second elastic member is provided between the second shielding structure 14 and the first housing 11. The second elastic member is used to make the other side of the second shielding structure 14 tightly adhere to the outer wall of the waste chamber 110. The second elastic member provides a certain pre-tightening force to the second shielding structure 14, making the second shielding structure 14 tightly adhere to the inner wall of the waste chamber 110. Specifically, when there is no external force, the side of the second shielding structure 14 away from its rotation axis is tightly adhered to the outer wall of the waste chamber 110, thereby blocking the waste inlet 111. When a negative pressure is generated in the dust collection chamber 210, the negative pressure causes the second shielding structure 14 to rotate relative to the first housing 11, the waste outlet 112 opens, and the waste enters the dust collection channel 211 through the waste outlet 112.

[0056] Please refer to some embodiments of this utility model. Figure 3 One side of the first shielding structure 13 is rotatably connected to the first housing 11. A first elastic member is provided between the first shielding structure 13 and the first housing 11, and the first elastic member is used to make the other side of the first shielding structure 13 fit tightly against the inner wall of the waste chamber 110. At the same time, one side of the second shielding structure 14 is rotatably connected to the first housing 11. A second elastic member is provided between the second shielding structure 14 and the first housing 11, and the second elastic member is used to make the other side of the second shielding structure 14 fit tightly against the outer wall of the waste chamber 110.

[0057] Please refer to some embodiments of this utility model. Figures 4 to 7 A buffer member 23 is protruding at the dust collection inlet 2110 and surrounds the dust collection inlet 2110. A docking structure 15 extends from the first shell 11 at the waste outlet 112, surrounding the waste outlet 112 and used to contact the buffer member 23, so that the waste outlet 112 and the dust collection inlet 2110 are directly opposite each other. The buffer member 23 is a structure that can be compressed and deformed under external force. Because it surrounds the dust collection inlet 2110, the buffer member 23 is a hollow cylindrical structure. The docking structure 15 is a rigid structure and surrounds the waste outlet 112; therefore, the docking structure 15 is also a hollow cylindrical structure. When the host 10 is collecting waste, the docking structure 15 and the buffer 23 are in contact with each other and facing each other. The waste outlet 112 and the dust collection inlet 2110 are set facing each other. The buffer 23 is compressed and deformed to seal the contact gap between the docking structure 15 and the buffer 23, preventing waste from leaking from the gap between the host 10 and the charging dust collection station 20.

[0058] By setting the buffer 23, when the host 10 and the charging dust collection station 20 are connected to each other, the garbage leaks out from the gap between the host 10 and the charging dust collection station 20.

[0059] In some embodiments, the cushioning element 23 is made of rubber, but may also be made of materials such as foam.

[0060] In some embodiments, the inner wall dimension of the docking structure 15 is smaller than the inner wall dimension of the buffer member 23. The inner wall dimension of the docking structure 15 refers to the dimension of the inner wall of its cross-section, and the inner wall dimension of the buffer member 23 refers to the dimension of the inner wall of its cross-section. When the docking structure 15 and the buffer member 23 abut against each other, the end of the buffer member 23 near its inner wall is blocked by the docking structure 15, and the waste will not be stopped by the buffer member 23 when passing from the waste outlet 112 through the docking structure 15 to the buffer member 23. Conversely, if the inner wall dimension of the docking structure 15 is larger than the inner wall dimension of the buffer member 23, the waste is more easily stopped by the end wall of the buffer member 23.

[0061] Please refer to some embodiments of this utility model. Figures 6 to 7 The buffer 23 includes a compression portion 231 and a sealing mounting portion 232 connected to each other. The compression portion 231 is located outside the second housing 21 and is a telescopic folding structure. The inner wall of the sealing mounting portion 232 has a cavity 2321. The second housing 21 has an insert portion 212 extending into the cavity 2321 at the dust collection inlet 2110. The outer wall of the second housing 21 has a clamping portion 213 for pressing the sealing mounting portion 232 against the insert portion 212. The compression portion 231 is located outside the second housing 21 and is used to contact the docking structure 15. The compression portion 231 can be folded and deformed under pressure. The inner and outer walls of the sealing mounting portion 232 are clamped by the insert portion 212 and the clamping portion 213, respectively, thereby sealing the buffer 23 onto the second housing 21.

[0062] By configuring the compression part 231 as a folded structure, the compression part 231 can withstand compression while having a longer service life, a higher compression ratio, and stronger sealing ability. By providing a cavity 2321 in the sealing mounting part 232, the second housing 21 can more tightly press the sealing mounting part 232, eliminating the gap between the sealing mounting part 232 and the second housing 21.

[0063] In some embodiments, both the sealing mounting portion 232 and the compression portion 231 are thin-walled structures, making them easier to compress and easier to install into the second housing 21.

[0064] Please refer to some embodiments of this utility model. Figure 2 and Figure 4A first conductive structure 12 protrudes from the first housing 11, and a second conductive structure 22 protrudes from the second housing 21. One of the first conductive structure 12 and the second conductive structure 22 has a vertical length direction, and the other has a horizontal length direction. The protruding design of both the first conductive structure 12 and the second conductive structure 22 facilitates easier contact between the first conductive structure 12 and the second conductive structure 22 when they are close to each other. Both the first conductive structure 12 and the second conductive structure 22 are elongated strips, and when they contact each other, they combine to form a cross-shaped structure.

[0065] By setting one of the length directions of the first conductive structure 12 and the second conductive structure 22 to the vertical direction and the other length direction to the horizontal direction, when the host 10 and the charging dust collection station 20 are in contact with each other, even if their positions are slightly offset horizontally or vertically, the first conductive structure 12 and the second conductive structure 22 can still make contact and conduct electricity, thus avoiding the situation where the host 10 and the charging dust collection station 20 are misaligned and cannot be charged.

[0066] Please refer to some embodiments of this utility model. Figure 2 A laser 16 for detecting obstacles is provided on the top of the first housing 11. The laser 16 is used to scan obstacles around the host 10 to prevent the host 10 from colliding with obstacles when it moves.

[0067] In some embodiments of this utility model, a garbage bag is detachably connected inside the dust collection chamber 210. When the garbage bag inside the dust collection chamber 210 is full of garbage, the garbage bag can be removed and replaced with a new garbage bag. In this way, it is not necessary to clean the dust collection chamber 210.

[0068] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
