Description

Technical Field

[0001] This utility model relates to the field of cleaning technology, specifically to base stations, sweeping machines, and cleaning equipment. Background Technology

[0002] A cleaning robot is a device equipped with an artificial intelligence system that can automatically clean floors in a room. On the one hand, cleaning robots reduce the intensity of indoor cleaning work for users; on the other hand, the AI ​​system itself provides a degree of entertainment, enriching users' lives to some extent, and thus they are very popular.

[0003] Currently, cleaning robots on the market generally consist of a base station and a sweeper. The base station is used to perform maintenance tasks such as dust collection, sewage removal, and water replenishment on the sweeper after it returns to its enclosure. When the sweeper needs to enter the base station for maintenance after completing its cleaning work, it is usually aligned with the base station's infrared module. Maintenance work can only begin when the sweeper stops in the correct position. However, achieving precise alignment of the sweeper using an infrared module requires sophisticated control algorithms, increasing product development costs. Utility Model Content

[0004] In view of this, the present invention provides a base station, a sweeping machine, and cleaning equipment to solve the problem that existing cleaning equipment uses infrared modules to achieve precise alignment of the sweeping machine, which increases the product development cost.

[0005] In a first aspect, this utility model provides a base station for connecting with a sweeping robot, comprising:

[0006] The base station body has a accommodating cavity with an opening, and the accommodating cavity is used to place the sweeper.

[0007] An infrared module, located within the accommodating cavity, is used to provide infrared alignment for the sweeping robot to return to the base station;

[0008] The first guide structure is located near the opening of the accommodating cavity and is used to cooperate with the second guide structure on the sweeper to provide a first-level guide for the sweeper and the base station;

[0009] The third guiding structure is located inside the accommodating cavity, close to the infrared module, and is used to cooperate with the fourth guiding structure on the sweeping machine to provide final guidance for the sweeping machine to complete the alignment with the base station.

[0010] Beneficial effects: By setting an infrared module inside the accommodating cavity, the infrared module can provide infrared alignment for the robot vacuum cleaner's far-field return to the base station. When the robot vacuum cleaner is about to return to the base station, a first guide structure is set near the opening of the accommodating cavity. This first guide structure can cooperate with a second guide structure on the robot vacuum cleaner to achieve the first-level guidance for the initial contact between the robot vacuum cleaner and the base station, providing the first-level guidance for the robot vacuum cleaner to enter the charging area. By setting a third guide structure near the infrared module, this third guide structure can cooperate with a fourth guide structure on the robot vacuum cleaner to achieve the final guidance for the robot vacuum cleaner to complete the alignment with the base station, providing the final guidance for the robot vacuum cleaner to enter the charging area. After the robot vacuum cleaner and the base station are docked, the setting of the infrared module, the cooperation of the first and second guide structures, and the cooperation of the third and fourth guide structures provide accurate guidance and alignment for the robot vacuum cleaner and the base station during far-field and near-field return, without having to invest too much cost in control algorithms during the product development stage, thus reducing R&D costs.

[0011] In one optional implementation, the base station includes:

[0012] The fifth guide structure is located within the accommodating cavity, between the first guide structure and the third guide structure, and is used to cooperate with the sixth guide structure on the sweeper to provide a second level of guidance for the sweeper and the base station.

[0013] Beneficial effects: By setting a fifth guiding structure in the accommodating cavity, the fifth guiding structure is located between the first and third guiding structures. The fifth guiding structure can cooperate with the sixth guiding structure on the sweeper to achieve the second level of guidance for the sweeper and the base station during the near-field recharging process. In conjunction with the first and third guiding structures, the sweeper can achieve precise alignment by passing through the first level of guidance, the second level of guidance and the final guidance step by step during the recharging process of the sweeper to the base station, thus completing the recharging of the sweeper and improving the alignment accuracy of the sweeper during recharging.

[0014] In one optional embodiment, a first assembly gap is provided between the first guide structure and the second guide structure, a second assembly gap is provided between the fifth guide structure and the sixth guide structure, and a third assembly gap is provided between the third guide structure and the fourth guide structure. The first assembly gap is larger than the second assembly gap, and the second assembly gap is larger than the third assembly gap.

[0015] Beneficial effects: By setting the first assembly gap to be larger than the second assembly gap, and the second assembly gap to be larger than the third assembly gap, the guiding and positioning accuracy of the sweeper and the base station during the recharging process is improved step by step, thereby achieving precise alignment between the sweeper and the base station. The structure is relatively simple.

[0016] In one optional embodiment, the fifth guide structure is disposed at the bottom of the accommodating cavity;

[0017] And / or, the fifth guide structure is provided in at least two forms;

[0018] And / or, a support structure is provided on the fifth guide structure, the support structure being configured to contact the sixth guide structure;

[0019] And / or, the fifth guiding structure is a guide block, and the sixth guiding structure is a guide groove.

[0020] Beneficial effects: During the process of the sweeper returning to the base station, it first passes through the opening of the receiving cavity and then gradually enters the receiving cavity. By placing the fifth guide structure at the bottom of the receiving cavity, it is convenient to realize the second-level guidance for the sweeper's return to the base station. By setting at least two fifth guide structures, more guiding support can be provided for the sweeper. By setting a support structure on the fifth guide structure, which is used to contact the sixth guide structure on the sweeper, the support effect of the base station on the sweeper can be further improved, preventing the sweeper from shifting up and down. By setting the fifth guide structure as a guide block and the sixth guide structure as a guide groove, it is convenient to connect and the structure is simpler.

[0021] In one alternative implementation, at least two of the fifth guiding structures are symmetrically arranged along the central axis of the base station.

[0022] Beneficial effects: By symmetrically arranging at least two fifth guide structures along the central axis of the base station, the left and right swing amplitude of the sweeper during the recharging process can be limited, and the alignment accuracy can be improved while guiding.

[0023] In one optional embodiment, the first guide structure is disposed within the accommodating cavity;

[0024] And / or, the first guide structure is provided in at least two, respectively disposed on two side walls near the opening of the accommodating cavity;

[0025] And / or, the first guiding structure is a guide block, and the second guiding structure is the side wall of the sweeper;

[0026] And / or, the third guide structure is disposed on the inner wall of the accommodating cavity opposite to the opening;

[0027] And / or, the third guiding structure is a guide post, and the fourth guiding structure is a guide hole;

[0028] And / or, the infrared module is disposed on the inner wall of the accommodating cavity opposite to the opening.

[0029] Beneficial effects: By placing the first guide structure within the accommodating cavity, it facilitates guiding the sweeper towards the base station; by providing at least two first guide structures, each positioned on one of the two side walls of the cavity opening, it provides guidance in both left and right directions simultaneously, offering more guidance for the sweeper and preventing it from deviating in one direction; by setting the first guide structure as a guide block and the second guide structure directly as the sweeper's side wall, there is no need for a separate second guide structure, simplifying the overall structure of the sweeper; by placing the third guide structure on the inner wall of the accommodating cavity opposite the opening, it can lift the rear of the sweeper. The first guide structure provides alignment support for the left and right sides of the sweeper, while the fifth guide structure provides alignment support for the bottom of the sweeper. Therefore, the first, fifth, and third guide structures work together to provide all-round alignment support for the left and right sides, bottom, and rear of the sweeper, improving alignment accuracy. By setting the third guide structure as a guide post and the fourth guide structure as a guide hole, the structure of the guide structure is relatively simple. By placing the infrared module on the inner wall of the accommodating cavity opposite to the opening, the rear of the sweeper can be aligned, ensuring the final alignment effect of the sweeper.

[0030] In one alternative implementation, at least two of the first guide structures are symmetrically arranged along the central axis of the base station;

[0031] And / or, the infrared module is located on the central axis of the base station.

[0032] Beneficial effects: By symmetrically arranging at least two first guide structures along the central axis of the base station, the left and right swing amplitude of the sweeper can be limited, improving the centering stability; by placing the infrared module on the central axis of the base station, it is beneficial for the sweeper to recharge and center.

[0033] In one optional implementation, the base station includes:

[0034] A water replenishment device is used to connect with the water replenishment hole of the sweeper to replenish water to the sweeper;

[0035] And / or, a sewage discharge device, used to connect in conjunction with the sewage discharge button of the sweeper to realize the sewage discharge of the sweeper.

[0036] Beneficial effects: By installing both the water replenishment device and the sewage discharge device on the base station, more maintenance work can be done for the sweeper after it returns to the base station for charging.

[0037] In one optional embodiment, the water replenishment device and the third guide structure are symmetrically arranged along the central axis of the base station;

[0038] And / or, the water replenishment device is used for a sealed connection with the water replenishment hole;

[0039] And / or, the sewage discharge device and the third guide structure are located on the same side of the central axis of the base station;

[0040] And / or, the sewage discharge device is a top rod structure, used to press the sewage discharge button when or after the sweeper and the base station are aligned, so as to discharge the sewage from the sweeper.

[0041] Beneficial effects: Since the water replenishment device can be connected to the water replenishment hole on the sweeper, it can also play a certain guiding role. By symmetrically setting the water replenishment device and the third guiding structure along the central axis of the base station, the water replenishment device and the third guiding structure together provide guidance for the sweeper and limit the left and right swing amplitude of the sweeper. By sealing the water replenishment device to the water replenishment hole, water leakage during the water replenishment process can be prevented. Since the assembly gap between the third guiding structure and the fourth guiding structure is the smallest, the third guiding structure is the most precise guiding structure. By setting the sewage discharge device and the third guiding structure on the same side of the central axis of the base station, the docking accuracy of the sewage discharge device can be improved. By setting the sewage discharge device as a top rod structure, the sewage discharge button can be pressed when or after the sweeper and the base station are aligned, making it easy to discharge the sewage from the sweeper.

[0042] Secondly, this utility model also provides a sweeping machine for connecting with the aforementioned base station, comprising:

[0043] The sweeping robot body is provided with a second guide structure and a fourth guide structure, the second guide structure being configured corresponding to the first guide structure, and the fourth guide structure being configured corresponding to the third guide structure.

[0044] Beneficial effects: Since the sweeping robot is used to connect with the aforementioned base station, it has the same effect as the aforementioned base station, which will not be elaborated here.

[0045] Thirdly, this utility model also provides a cleaning device, comprising:

[0046] The aforementioned base stations;

[0047] The aforementioned sweeping machine is connected in conjunction with the base station.

[0048] Beneficial effects: Since the cleaning equipment includes the aforementioned base station and sweeper, it has the same effect as the aforementioned base station and sweeper, and will not be described in detail here. Attached Figure Description

[0058] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0059] Currently, cleaning robots on the market generally consist of a base station and a sweeper. The base station is used to perform maintenance tasks such as dust collection, sewage removal, and water replenishment on the sweeper after it returns to its enclosure. When the sweeper needs to enter the base station for maintenance after completing its cleaning work, it is usually aligned with the base station's infrared module. Maintenance work can only begin when the sweeper stops in the correct position. However, achieving precise alignment of the sweeper using an infrared module requires sophisticated control algorithms, increasing product development costs.

[0060] The following is combined with Figures 1 to 5 The following describes embodiments of the present invention.

[0061] According to an embodiment of the present invention, in a first aspect, a base station is provided for connection with a sweeping robot 2, comprising:

[0062] The base station body has a accommodating cavity with an opening, and the accommodating cavity is used to place the sweeper 2.

[0063] Infrared module 101, located inside the accommodating cavity, is used to provide infrared alignment for the sweeping robot 2 to return to base station 1;

[0064] The first guide structure 102 is located near the opening of the accommodating cavity and is used to cooperate with the second guide structure 201 on the sweeper 2 to provide the first-level guidance between the sweeper 2 and the base station 1.

[0065] The third guide structure 103 is located inside the accommodating cavity, close to the infrared module 101, and is used to cooperate with the fourth guide structure 202 on the sweeper 2 to provide the final guidance for the sweeper 2 to complete the alignment with the base station 1.

[0066] By installing an infrared module 101 within the accommodating cavity, the infrared module 101 can provide infrared alignment for the far-field return of the sweeping robot 2 to the base station 1. When the sweeping robot 2 is about to return to the base station 1, a first guide structure 102 is installed near the opening of the accommodating cavity. The first guide structure 102 can cooperate with the second guide structure 201 on the sweeping robot 2 to achieve the first-level guidance for the initial contact between the sweeping robot 2 and the base station 1, providing the first-level guidance for the sweeping robot 2 to enter the field for recharging. By installing a third guide structure 103 near the infrared module 101, the third guide structure 103 can cooperate with the sweeping robot... The fourth guide structure 202 on the robot vacuum 2 works in conjunction with the base station 1 to achieve the final guidance for the robot vacuum 2 to complete the alignment. This provides the robot vacuum 2 with the final guidance for entering the charging area. The robot vacuum 2 and the base station 1 complete the docking. The setting of the infrared module 101, the coordination of the first guide structure 102 and the second guide structure 201, and the coordination of the third guide structure 103 and the fourth guide structure 202 provide precise guidance and alignment for the robot vacuum 2 and the base station 1 during far-field and near-field return, without having to invest too much cost in the control algorithm during the product development stage, thus reducing R&D costs.

[0067] In one embodiment, the opening of the accommodating cavity is located at the front end of the base station 1, and the infrared module 101 is located on the inner wall of the accommodating cavity opposite to the opening, that is, the infrared module 101 is located at the rear end of the base station 1. Here, the front end refers to the end closer to the operator, and the rear end refers to the end farther away from the operator. As an alternative implementation, the opening of the accommodating cavity may also be located in other directions of the base station 1, without much limitation here.

[0068] By placing the infrared module 101 on the inner wall of the accommodating cavity opposite to the opening, the tail of the sweeper 2 can be aligned, ensuring the final alignment effect of the sweeper 2. As an alternative implementation, the infrared module 101 can also be placed in other positions within the accommodating cavity; no further restrictions are imposed here.

[0069] Specifically, the accommodating cavity is a U-shaped cavity with an opening at the front end, and the infrared module 101 is located at the bottom of the U-shaped cavity, i.e., the rear end. As an alternative implementation, the accommodating cavity can also be of other shapes, as long as one end has an opening; no further restrictions are imposed here.

[0070] In one embodiment, the infrared module 101 is located on the central axis of the base station 1. Positioning the infrared module 101 on the central axis of the base station 1 facilitates the recharging and centering of the entire sweeping robot 2. Alternatively, the infrared module 101 can be located near the central axis of the base station 1.

[0071] like Figure 1As shown, in one embodiment, the first guide structure 102 is disposed within the accommodating cavity to facilitate guiding the sweeper 2 into the base station 1. Alternatively, the first guide structure 102 may be disposed outside the accommodating cavity, such as near the opening of the accommodating cavity or on the outer wall of the accommodating cavity. In this case, a guide surface extending into the accommodating cavity can be provided on the first guide structure 102 to better guide the sweeper 2 into the base station 1. Alternatively, the first guide structure 102 may be disposed on the side wall of the base station 1 facing the operator at the opening.

[0072] The first guide structure 102 is provided in two parts, respectively located on the two inner walls near the opening of the accommodating cavity. It can provide guidance in both left and right directions simultaneously, providing more guidance for the sweeper 2 and preventing the sweeper 2 from deviating in one direction. As an alternative implementation, one first guide structure 102 may be provided, located on one inner wall near the opening of the accommodating cavity, or three or more first guide structures 102 may be provided.

[0073] In one embodiment, the two first guide structures 102 are symmetrically arranged along the central axis of the base station 1, which can limit the left and right swing amplitude of the sweeping robot 2 and improve the centering stability. As an alternative implementation, the two first guide structures 102 may not be symmetrically arranged along the central axis of the base station 1.

[0074] Specifically, the first guide structure 102 is a guide block, and the second guide structure 201 is the side wall of the sweeper 2. By setting the first guide structure 102 as a guide block and the second guide structure 201 directly as the side wall of the sweeper 2, there is no need to set up a separate second guide structure 201, making the overall structure of the sweeper 2 simpler. As an alternative implementation, the first guide structure 102 can also be a guide wheel. As an alternative implementation, the second guide structure can also be a guide structure additionally set on the side wall of the sweeper 2, such as a guide block or a guide wheel, which contacts the first guide structure 102 to guide the sweeper 2.

[0075] like Figure 3 As shown, the first guide structure 102 has a guide slope extending from the opening of the accommodating cavity into the accommodating cavity, and the guide slope can specifically be an arc-shaped surface. When the side wall of the sweeper 2 contacts the guide surface of the first guide structure 102, it can move into the accommodating cavity under the guidance of the first guide structure 102 to ensure the guiding effect. As an alternative implementation, the guide slope can also be a straight slope.

[0076] Specifically, the third guide structure 103 is a guide post, and the fourth guide structure 202 is a guide hole. By setting the third guide structure 103 as a guide post and the fourth guide structure 202 as a guide hole, the structure of the guide structure is relatively simple. Of course, in other embodiments, the third guide structure 103 can also be a guide hole and the fourth guide structure 202 a guide post. The specific configuration can be adjusted according to actual needs, and no further restrictions are imposed here. Generally, the sweeper 2 is provided with a water replenishment hole 204, and the base station 1 is provided with a water replenishment device 105. Since the third guide structure 103 is located on the base station 1, by setting the third guide structure 103 as a guide post, the third guide structure 103 can be correspondingly set with the water replenishment device 105. Since the water replenishment hole 204 and the fourth guide structure 202 are located on the sweeper 2, by setting the fourth guide structure 202 as a guide hole, the guide hole can be correspondingly set with the water replenishment hole 204. This facilitates the docking of the base station 1 and the sweeper 2, and also makes the appearance of the sweeper 2 and the base station 1 neater and more aesthetically pleasing.

[0077] In one embodiment, base station 1 includes:

[0078] The fifth guide structure 104 is located in the accommodating cavity, between the first guide structure 102 and the third guide structure 103, and is used to cooperate with the sixth guide structure 203 on the sweeper 2 to provide a second-level guide for the sweeper 2 and the base station 1.

[0079] By setting a fifth guide structure 104 in the accommodating cavity, the fifth guide structure 104 is located between the first guide structure 102 and the third guide structure 103. The fifth guide structure 104 can cooperate with the sixth guide structure 203 on the sweeper 2 to realize the second-level guidance of the sweeper 2 and the base station 1 during the near-field recharging process. In cooperation with the first guide structure 102 and the third guide structure 103, the sweeper 2 passes through the first-level guidance, the second-level guidance and the final guidance step by step during the recharging process of the sweeper 2 to the base station 1, so as to achieve precise alignment and complete the recharging of the sweeper 2, thereby improving the alignment accuracy of the sweeper 2 during recharging.

[0080] Alternatively, the base station 1 may not include the fifth guiding structure 104. Accordingly, the sweeping robot 2 may not need to be equipped with the sixth guiding structure 203. When the sweeping robot 2 returns to the base station 1 from a distance, it first achieves far-field return through infrared alignment, and then achieves near-field return alignment accuracy through the first-level guidance and the final guidance.

[0081] like Figure 1As shown, in one embodiment, the fifth guide structure 104 is located at the bottom of the receiving cavity, where the bottom of the receiving cavity refers to the lower inner wall of the receiving cavity. Since the sweeping robot 2 will first pass through the opening of the receiving cavity and then gradually penetrate into the receiving cavity during the recharging process to the base station 1, placing the fifth guide structure 104 at the bottom of the receiving cavity facilitates the second-level guidance for the sweeping robot 2 during recharging. Alternatively, the fifth guide structure 104 can be located at other positions within the receiving cavity, as long as it is located between the first guide structure 102 and the third guide structure 103, along the path of the sweeping robot 2 as it travels from the opening of the receiving cavity into the receiving cavity.

[0082] Two fifth guide structures 104 are provided, which can provide more guiding support for the sweeper 2. As an alternative implementation, there may be one, three, or more fifth guide structures 104.

[0083] The two fifth guide structures 104 are symmetrically arranged along the central axis of the base station 1. This limits the left and right swing amplitude of the sweeping robot 2 during the recharging process, improving alignment accuracy while providing guidance. As an alternative implementation, the two fifth guide structures 104 may not be symmetrically arranged along the central axis of the base station 1.

[0084] like Figure 4 As shown, a support structure 1041 is provided on the fifth guide structure 104. The support structure 1041 is used to contact the sixth guide structure 203, which can further improve the support effect of the base station 1 on the sweeper 2 and prevent the sweeper 2 from shifting up and down. As an alternative implementation, the support structure 1041 may not be provided on the fifth guide structure 104.

[0085] Specifically, the support structure 1041 is a support rib, and multiple support ribs are provided on each fifth guide structure 104. As a variant implementation, the support structure 1041 can also be a support block. As a variant implementation, each fifth guide structure 104 can also be provided with one support rib.

[0086] Specifically, the fifth guide structure 104 is a guide block, and the sixth guide structure 203 is a guide groove, which facilitates connection and simplifies the structure. As an alternative implementation, the fifth guide structure 104 can be a guide groove, and the sixth guide structure 203 can be a guide block.

[0087] The sixth guide structure 203 has a side wall and a top wall. When the sweeper 2 runs to the point where the fifth guide structure 104 contacts the sixth guide structure 203, the side wall of the sixth guide structure 203 contacts the fifth guide structure 104, providing a second-level guide for the sweeper 2 to return. When the second-level guide is completed, the supporting ribs of the fifth guide structure 104 contact the top wall of the sixth guide structure 203 to support the sweeper 2.

[0088] like Figure 1 As shown, the opening of the accommodating cavity is located at the front end of the base station 1, and the third guiding structure 103 is located on the inner wall of the accommodating cavity opposite to the opening, that is, the third guiding structure 103 is located at the rear end of the base station 1. Here, the front end refers to the end closer to the operator, and the rear end refers to the end farther away from the operator. As an alternative implementation, the opening of the accommodating cavity may also be located in other directions of the base station 1, without much restriction here.

[0089] By placing the third guide structure 103 on the inner wall of the accommodating cavity opposite to the opening, it can provide alignment support for the tail of the sweeper 2. The first guide structure 102 can provide alignment support for the left and right sides of the sweeper 2, and the fifth guide structure 104 can provide alignment support for the bottom of the sweeper 2. Therefore, the first guide structure 102, the fifth guide structure 104 and the third guide structure 103 can jointly provide all-round alignment support for the left and right sides, bottom and tail of the sweeper 2, improving the alignment accuracy.

[0090] In one embodiment, a first assembly gap exists between the first guide structure 102 and the second guide structure 201, a second assembly gap exists between the fifth guide structure 104 and the sixth guide structure 203, and a third assembly gap exists between the third guide structure 103 and the fourth guide structure 202. The first assembly gap is larger than the second assembly gap, and the second assembly gap is larger than the third assembly gap. Here, the assembly gap refers to the gap between the two structures after the sweeper 2 and the base station 1 are aligned. For example, the first assembly gap refers to the gap between the first guide structure 102 and the second guide structure 201 after the sweeper 2 and the base station 1 are aligned; the second assembly gap refers to the gap between the fifth guide structure 104 and the sixth guide structure 203 after the sweeper 2 and the base station 1 are aligned; and the third assembly gap refers to the gap between the third guide structure 103 and the fourth guide structure 202 after the sweeper 2 and the base station 1 are aligned.

[0091] By setting the first assembly gap to be larger than the second assembly gap, and the second assembly gap to be larger than the third assembly gap, the guiding and positioning accuracy of the sweeper 2 and the base station 1 during the recharging process is gradually improved, thereby achieving precise alignment between the sweeper 2 and the base station 1. The structure is relatively simple.

[0092] like Figure 1 and Figure 3As shown, in one embodiment, base station 1 includes:

[0093] The water replenishment device 105 is used to connect with the water replenishment hole 204 of the sweeper 2 to replenish water to the sweeper 2;

[0094] The sewage discharge device 106 is used to connect with the sewage discharge button 205 of the sweeper 2 to realize the sewage discharge of the sweeper 2.

[0095] By installing both the water replenishment device 105 and the sewage discharge device 106 on the base station 1, more maintenance work can be provided for the sweeper 2 after it returns to the base station 1 for recharging.

[0096] As an alternative implementation, base station 1 may only include water replenishment device 105 or sewage discharge device 106, or base station 1 may also be equipped with other functional devices as needed, without further restrictions.

[0097] The water replenishment device 105 and the third guide structure 103 are symmetrically arranged along the central axis of the base station 1. Since the water replenishment device 105 can connect with the water replenishment hole 204 on the sweeper 2, it also provides a guiding function. By symmetrically arranging the water replenishment device 105 and the third guide structure 103 along the central axis of the base station 1, they together provide guidance for the sweeper 2, limiting its left-right swaying amplitude. Alternatively, the water replenishment device 105 and the third guide structure 103 may not be symmetrically arranged along the central axis of the base station 1.

[0098] The water replenishment device 105 is used to seal the water replenishment hole 204 on the sweeper 2, so as to prevent water from leaking out during the water replenishment process.

[0099] Specifically, the water replenishment device 105 is equipped with a sealing device. After the water replenishment device 105 extends into the water replenishment hole 204, the periphery of the sealing device is press-fitted with the periphery of the water replenishment hole 204 to seal. Specifically, the sealing device is a sealing ring. As an alternative implementation, the sealing device can also be of other forms, as long as it can perform the sealing function; no further restrictions are imposed here.

[0100] In one embodiment, the sewage discharge device 106 and the third guide structure 103 are located on the same side of the central axis of the base station 1. For example... Figure 1 As shown, the sewage discharge device 106 is located below the third guide structure 103. Alternatively, the sewage discharge device 106 may be located above or to the left of the third guide structure 103.

[0101] Since the assembly gap between the third guide structure 103 and the fourth guide structure 202 is the smallest, the third guide structure 103 is the guide structure with the highest precision. By placing the sewage discharge device 106 and the third guide structure 103 on the same side of the central axis of the base station 1, the docking precision of the sewage discharge device 106 can be improved.

[0102] Alternatively, the sewage discharge device 106 and the third guide structure 103 may be located on opposite sides of the central axis of the base station 1.

[0103] Specifically, the sewage discharge device 106 is a top rod structure, used to discharge sewage from the sweeper 2 by pressing the sewage discharge button 205 when or after the sweeper 2 and base station 1 are aligned.

[0104] By setting the sewage discharge device 106 as a top rod structure, the sewage discharge button 205 can be pressed when or after the sweeper 2 and the base station 1 are aligned, so as to facilitate the discharge of sewage from the sweeper 2.

[0105] like Figure 5 As shown, the drain button 205 is a rotating structure. The contact position between the drain device 106 and the drain button 205 is located above the rotation center 2051, and the drain port 206 is located below the rotation center 2051. When the drain device 106 contacts the drain button 205, the drain button 205 rotates around the rotation center 2051, opening the drain port 206 to drain the sewage.

[0106] When the sweeper 2 enters the near-field recharging phase, the two first guide structures 102 of the base station 1 interact with the left and right side walls of the sweeper 2 to provide the first level of guidance for the sweeper 2 during the recharging process. As the sweeper 2 continues to move, the fifth guide structure 104 of the base station 1 interacts with the side wall of the sixth guide structure 203 on the sweeper 2 to provide the second level of guidance for the sweeper 2 during the recharging process. When the second level of guidance is completed, the top of the supporting rib of the fifth guide structure 104 interacts with the top wall of the sixth guide structure 203 to support the sweeper 2. As the sweeper 2 continues to move, the third guide structure 103 of the base station 1 interacts with the fourth guide structure 202 of the sweeper 2 to provide the final guidance for the sweeper 2 during the recharging process, and also to prevent the tail of the sweeper 2 from lifting up and the whole machine from floating.

[0107] When the sweeper 2 completes alignment and recharging with the base station 1, or after alignment and recharging, the water replenishment device 105 of the base station 1 cooperates with the water replenishment hole 204 of the sweeper 2 to replenish water to the sweeper 2. The water replenishment device 105 has a sealing ring. After the water replenishment device 105 extends into the water replenishment hole 204, the periphery of the sealing ring and the periphery of the water replenishment hole 204 are press-fitted. The sewage discharge device 106 of the base station 1 is located below the third guide structure 103, which allows for more precise docking of the sewage discharge device 106. The sewage discharge device 106, in conjunction with the sewage discharge button 205 of the sweeper 2, discharges the sewage inside the sweeper 2.

[0108] In general, during the recharge alignment process, the sweeping robot 2 uses infrared alignment to find and approach the base station 1 when at a long distance, and gradually improves the alignment accuracy of the whole machine by using the first-level guide, the second-level guide and the final guide in sequence when at a close distance. That is, the first assembly gap is greater than the second assembly gap, and the second assembly gap is greater than the third assembly gap.

[0109] The docking actions such as water replenishment and sewage discharge between base station 1 and sweeping machine 2 are carried out at the same time or after base station 1 and sweeping machine 2 have completed docking, in order to ensure alignment accuracy and ensure normal operation of functions.

[0110] like Figure 2 As shown, according to an embodiment of the present invention, in a second aspect, a sweeping robot is also provided for connection with the aforementioned base station 1, comprising:

[0111] The sweeper body is provided with a second guide structure 201 and a fourth guide structure 202. The second guide structure 201 is corresponding to the first guide structure 102, and the fourth guide structure 202 is corresponding to the third guide structure 103.

[0112] like Figure 2 As shown, the sweeper body is provided with a sixth guide structure 203, which is correspondingly set with the fifth guide structure 104.

[0113] Among them, the second guide structure 201 is the left and right side walls of the sweeper body, the fourth guide structure 202 is the guide hole, and the sixth guide structure 203 is the guide groove.

[0114] According to an embodiment of the present invention, in a third aspect, a cleaning device is also provided, comprising:

[0115] The aforementioned base station 1;

[0116] The sweeper 2 mentioned above is connected to the base station 1.

[0117] To improve the recharge alignment accuracy of the sweeper 2, this invention sequentially installs a first guide structure 102, a third guide structure 103, and a fifth guide structure 104 on the side wall, base, and center of the base station 1. Correspondingly, a second guide structure 201, a fourth guide structure 202, and a sixth guide structure 203 are installed on the sweeper 2. This provides first-level guidance, second-level guidance, and final guidance for the sweeper 2's return to the base station 1. This allows the sweeper 2 to rely on infrared alignment for far-field recharge, and the near-field recharge process to sequentially pass through the first-level guidance, second-level guidance, and final guidance, with the positioning accuracy improving step by step. Finally, the various functional structures of the base station 1, such as the water replenishment device 105 and the sewage discharge device 106, interact with the sweeper 2 to perform water replenishment and sewage discharge operations.

[0118] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and all such modifications and variations fall within the scope defined by the appended claims.
