[0057] Next, the technical solutions of the present application will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the embodiments described in the present application are only a part of the embodiments, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments provided in the present application without creative efforts belong to the protection scope of the present application.

[0058] Referring to "embodiment" in the present application means that the specific features, structures or characteristics described in conjunction with the embodiment may be included in at least one embodiment of the present application. The phrase appears in various positions in the specification does not necessarily refer to the same embodiment, nor is it an exclusive, independent or alternative embodiment to other embodiments. Those skilled in the art can explicitly and implicitly understand that the embodiments described in the present application can be combined with other embodiments.

[0059] The terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example: A component or device including one or more parts is not limited to the one or more parts listed, but optionally further includes one or more parts not listed but inherent to the product shown, or one or more parts that should be had based on the described function.

[0060] Please refer to Figure 1 and Figure 2 , the present application provides a charging device 200, which can charge the outdoor self-moving device 100 working in a home courtyard, a manor, a hotel, etc. The self-moving device 100 includes but is not limited to a lawn mower, a snow sweeper, a cleaning robot, etc. In addition, the charging device can also charge an electric vehicle, an electric bike, etc.

[0061] Currently, the charging device 200 generally lacks protection designs against small organisms such as snails and slugs. Such organisms are likely to climb onto the surface of the charging device 200, which will cause signal shielding to the charging device 200; the mucus secreted by such small organisms may corrode the metal structure of the charging device 200, etc.

[0062] Please refer to Figures 1-3, the charging device 200 includes an infrared module 201. The infrared module 201 is used to detect whether the path of the self - moving device 100 during the process of returning to the charging station is accurate, and whether the charging module 102 of the self - moving device 100 is accurately docked with the charging component 202 on the charging device 200. If a snail climbs onto the housing of the charging device 200 and blocks key sensor modules such as the infrared module 201. This kind of blocking phenomenon will lead to a decrease in the device positioning accuracy and a weakening of the environmental perception ability, affecting the process of the self - moving device 100 returning to the charging station.

[0063] Please refer to Figure 1 , the charging device 200 further includes a charging component 202. The charging component 202 includes a second charging electrode plate. If a snail climbs to the second charging electrode plate, the mucus produced by the snail will corrode the second charging electrode plate, resulting in damage to the charging device 200, etc.

[0064] When the self - moving device 100 is charging at the charging device 200, such organisms are also likely to climb onto the surface of the self - moving device 100, which will cause signal blocking when the self - moving device 100 is working; the mucus secreted by such small organisms may corrode the metal structure of the self - moving device 100, etc.

[0065] In the embodiment of the present application, the self - moving device 100 is taken as a lawn mower as an example. The body housing of the lawn mower is provided with perception modules such as a vision sensor and a lidar. If a snail climbs onto the body housing of the lawn mower and blocks key perception modules such as the vision sensor or the lidar. This kind of blocking phenomenon will lead to a decrease in the device positioning accuracy and a weakening of the environmental perception ability. Seriously, it may cause the obstacle avoidance function to fail, affecting the normal working performance and safety reliability of the lawn mower. If a snail climbs to the charging electrode plate of the lawn mower, the mucus produced by the snail will corrode the charging electrode plate of the lawn mower, resulting in charging obstruction of the lawn mower, etc.

[0066] The current lawn mowers do not have an effective solution to prevent snails from climbing, which makes the vision module or lidar easily blocked, and the charging electrode plate of the lawn mower easily corroded, thus affecting the positioning and obstacle avoidance functions of the lawn mower and the damage of the charging electrode plate of the lawn mower, which may lead to a decrease in its working efficiency and accuracy.

[0067] Based on the above problems, please refer to Figure 1 , the present application proposes a charging device 200, which includes a chassis 220, a charging base 230 and at least one repelling device 40.

[0068] Please refer to Figure 1, the chassis 220 has a parking area 220a for parking the self - moving device 100. The charging base 230 is disposed on the chassis 220 and is located outside the parking area 220a. Optionally, the charging base 230 is disposed at the front end, or the rear end, or the side of the chassis 220, etc. The position of the charging base 230 on the chassis 220 corresponds to the position of the first charging electrode plate of the charging module 102 on the self - moving device 100.

[0069] The charging base 230 includes at least one component to be protected 12. The component to be protected 12 includes, but is not limited to, an infrared module 201, and / or a charging component 202, etc.

[0070] Optionally, please refer to Figure 1 , the repelling device 40 surrounds at least a part of the circumferential side of the chassis 220, or the repelling device 40 surrounds at least a part of the circumferential side of the component to be protected 12 of the charging base 230, so as to form a protection area on the circumferential side of the chassis 220 or the circumferential side of the component to be protected 12 of the charging base 230, such that the main body to be repelled changes its moving direction or stops moving when contacting the repelling device 40. This embodiment can not only effectively protect the charging base 230, but also effectively protect the self - moving device 100 parked in the parking area 220a.

[0071] At least a part of the circumferential side of the chassis 220 includes at least one of the front side, left side, rear side, and right side of the chassis 220.

[0072] At least a part of the circumferential side of the component to be protected 12 includes at least one of the front side, left side, rear side, and right side of the component to be protected 12.

[0073] Optionally, the repelling device 40 can be in a ring shape; or, the repelling device 40 can be in an open shape such as a straight line shape, an arc shape, a semi - ring shape, a broken line shape, a dot matrix shape, a line array shape, etc.

[0074] When the repelling device 40 can be in a ring shape, the ring - shaped repelling device 40 surrounds the circumferential side of the chassis 220 or the component to be protected 12 of the charging base 230.

[0075] When a repelling device 40 is in a semi - ring shape, a semi - ring - shaped repelling device 40 is disposed at the front, left, and rear sides of the chassis 220 or the charging base 230, or is disposed on the path where snails often crawl on the chassis 220 or the charging base 230.

[0076] When two repelling devices 40 are in a semi - ring shape, the two semi - ring - shaped repelling devices 40 are combined to form a ring and surround the circumferential side of the chassis 220 or the charging base 230.

[0077] When multiple repelling devices 40 are in an arc shape, the multiple arc-shaped repelling devices 40 are combined to form a ring, which is arranged around the circumference of the chassis 220 or the charging base 230.

[0078] For the convenience of description, in the following, the case where the repelling device 40 is in a ring shape and arranged around the four sides of the chassis 220 is taken as an example. Of course, the implementation manner when the repelling device 40 has other open structures can refer to this embodiment.

[0079] Generally, sensor modules such as the infrared module 201 are exposed outside the charging base 230. If a snail climbs onto the sensor module such as the infrared module 201 of the charging base 230, it will block the signal transmission and reception of the sensor module such as the infrared module 201, resulting in inaccurate signal acquisition, and further leading to problems such as inaccurate positioning accuracy of the self-moving device 100 when returning to the charging pile. The charging component 202 on the charging base 230 is exposed outside the charging base 230. For example, the second charging electrode plate is exposed outside the charging base 230. If a snail climbs onto the second charging electrode plate of the charging base 230, since the second charging electrode plate is made of metal, the mucus secreted by the snail will corrode the second charging electrode plate, resulting in corrosion of the second charging electrode plate and damage to the charging function of the charging base 230.

[0080] Generally, a part of the sensing module 101 of the self-moving device 100 is exposed outside the body shell of the self-moving device 100. For example, the vision sensor is exposed outside the body shell, and by collecting images or light, etc., the self-moving device 100 is positioned and obstacle detected. If a snail climbs onto the vision sensor on the body shell, it will block the vision sensor from emitting or receiving images or light, resulting in inaccurate signal acquisition by the vision sensor, and further leading to problems such as inaccurate device positioning accuracy or chaotic obstacle avoidance function. In addition, the lidar is exposed outside the body shell, and by emitting and receiving radar signals, etc., the self-moving device 100 is positioned. If a snail climbs onto the lidar on the body shell, it will block the lidar from emitting or receiving images or light, resulting in inaccurate signal acquisition by the lidar, and further leading to problems such as inaccurate device positioning accuracy. For example, the first charging electrode plate of the charging module 102 of the self-moving device 100 is exposed outside the body shell and is used to dock with the charging interface (such as the aforementioned charging component 202) on the charging base 230 to charge the self-moving device 100. If a snail climbs onto the first charging electrode plate on the body shell, since the first charging electrode plate is made of metal, the mucus secreted by the snail will corrode the first charging electrode plate of the lawn mower, resulting in corrosion of the charging electrode plate of the lawn mower and affecting the charging efficiency of the self-moving device 100.

[0081] The charging device 200 provided by the present application includes a chassis 220 and a charging base 230. The chassis 220 has a parking area 220a for parking the self-mobile device 100. The charging base 230 is provided on the chassis 220. The charging device 200 further includes a repelling device 40. The repelling device 40 surrounds at least a part of the circumferential side of the chassis 220 or at least a part of the circumferential side of the component 12 to be protected on the charging base 230, so as to form a protection area on the circumferential side of the chassis 220 or the circumferential side of the component 12 to be protected, such that the subject to be repelled changes its moving direction or stops moving when contacting the repelling device 40, avoiding the subject to be repelled from entering the protection area 13, thereby effectively protecting the charging base 230 and the self-mobile device 100 parked on the chassis 220, avoiding the component 12 to be protected on the charging base 230 from being blocked by the subject to be repelled or being affected by the mucus secreted by the subject to be repelled, and also avoiding the sensing module and charging module on the self-mobile device 100 during charging from being blocked by the subject to be repelled or being affected by the mucus secreted by the subject to be repelled, enabling the charging device 200 to have a good repelling function and self-protection function, and improving the reliability of the charging device 200.

[0082] The following embodiments specifically illustrate the position of the repelling device 40.

[0083] In the first alternative embodiment of the position of the repelling device 40, please refer to Figure 4 , the repelling device 40 is provided on the chassis 220.

[0084] Optionally, the repelling device 40 is annular and is provided at a position near the edge of the chassis 220 (such as the position indicated by S1 in Figure 4 ). The repelling device 40 sets the charging base 230 and the parking area 220a of the chassis 220 within the protection area 13. In other words, the repelling device 40 is disposed around the outer circumferential side of the charging base 230 and the parking area 220a of the chassis 220. Further optionally, the number of the repelling devices 40 is one, and one repelling device 40 is disposed around the outer circumferential side of the charging base 230 and the parking area 220a of the chassis 220. Still optionally, the number of the repelling devices 40 is two, one of the repelling devices 40 is disposed around the outer circumferential side of the charging base 230, and the other repelling device 40 is disposed around the outer circumferential side of the parking area 220a of the chassis 220.

[0085] In the second alternative embodiment of the position of the repelling device 40, please refer to Figure 1 , the repelling device 40 is provided on at least a part of the outer circumference of the chassis 220.

[0086] Optionally, the repelling device 40 is annular and disposed outside the chassis 220, and is disposed around the chassis 220. The repelling device 40 sets the charging base 230 and the parking area 220a of the chassis 220 within the protection area 13. In other words, the repelling device 40 is disposed around the outer peripheral side of the charging base 230 and the parking area 220a of the chassis 220.

[0087] In the third optional implementation manner of the position of the repelling device 40, please refer to Figure 5 , the repelling device 40 is disposed on the charging base 230. Further, the repelling device 40 is disposed on the charging base 230 and surrounds at least a part of the circumferential side of the component 12 to be protected. Figure 5 In [reference], the component 12 to be protected is disposed on a boss. The repelling device 40 is disposed around the outer periphery of the boss; or at a position near the edge of the tabletop of the boss; or, a part of the repelling device 40 is disposed at a position near the edge of the tabletop of the boss, and the other part is disposed around the outer periphery of the boss.

[0088] The component 12 to be protected includes but is not limited to components such as the sensor module 123 or the charging assembly 202 that are vulnerable to being invaded by small organisms such as snails and slugs.

[0089] Among them, the main body to be repelled includes but is not limited to small crawling organisms such as snails and slugs. Of course, the main body to be repelled can also include snakes, mice, etc., so as to prevent these organisms from affecting the operation of the sensor module 123 of the charging base 230 or corroding the metal components on the charging base 230. Among them, the sensor module 123 includes but is not limited to the infrared module 201, etc.

[0090] In this application, no specific limitation is imposed on the repelling device 40. The number of components 12 to be protected can be one or more.

[0091] When the number of components 12 to be protected is one, the number of repelling devices 40 is one. One repelling device 40 is disposed on at least a part of the circumferential side of the component 12 to be protected to form a protection area 13 on the circumferential side of the component 12 to be protected, so as to repel the main body to be repelled that is about to enter the protection area 13. For example, when the main body to be repelled contacts the repelling device 40, it stops moving or changes its moving direction, preventing the main body to be repelled from entering the protection area 13, and further preventing the component 12 to be protected from being blocked by the main body to be repelled or being affected by the mucus secreted by the main body to be repelled.

[0092] When the number of components 12 to be protected is one, the number of repelling devices 40 is multiple. The multiple repelling devices 40 can be arranged in a ring around the circumference of the component 12 to be protected; or each repelling device 40 is arranged around the circumference of the component 12 to be protected, and the multiple repelling devices 40 are distributed inside and outside around the circumference of the component 12 to form a protection area 13 around the circumference of the component 12, so as to repel the subject to be repelled that is about to enter the protection area 13. For example, the subject to be repelled stops moving or changes its moving direction when contacting the repelling device 40, preventing the subject to be repelled from entering the protection area 13, and further preventing the component 12 to be protected from being blocked by the subject to be repelled or affected by the mucus secreted by the subject to be repelled.

[0093] Please refer to Figure 5 , when the number of components 12 to be protected is multiple, the number of repelling devices 40 is one. One repelling device 40 is arranged around the circumference of the multiple components 12 to be protected to form a protection area 13 around the circumference of the multiple components 12 to be protected, so as to repel the subject to be repelled that is about to enter the protection area 13. For example, the subject to be repelled stops moving or changes its moving direction when contacting the repelling device 40, preventing the subject to be repelled from entering the protection area 13, and further preventing the component 12 to be protected from being blocked by the subject to be repelled or affected by the mucus secreted by the subject to be repelled. For example, one repelling device 40 encloses a protection area 13 to be protected, and the multiple components 12 to be protected are all located within the protection area 13 to be protected.

[0094] When the number of components 12 to be protected is multiple, the number of repelling devices 40 is multiple. Optionally, the multiple repelling devices 40 enclose to form a protection area 13, and the multiple components 12 to be protected are all located within the protection area 13; or, the multiple repelling devices 40 enclose to form multiple protection areas 13, and the multiple components 12 to be protected are respectively located within the multiple protection areas 13, so as to repel the subject to be repelled that is about to enter the multiple protection areas 13. For example, the subject to be repelled stops moving or changes its moving direction when contacting the repelling device 40, preventing the subject to be repelled from entering the protection area 13, and further preventing the component 12 to be protected from being blocked by the subject to be repelled or affected by the mucus secreted by the subject to be repelled.

[0095] The following embodiments of the present application give specific examples of the specific structure of the component 12 to be protected and the position of the repelling device 40.

[0096] Optionally, please refer to Figure 5 , at least one component 12 to be protected includes a sensor module 123. The repelling device 40 is arranged around at least part of the circumference of the sensor module 123. The sensor module 123 includes but is not limited to the sensor module 123. The sensor module 123 includes but is not limited to an infrared module 201, etc.

[0097] In this embodiment, by arranging the repelling device 40 around at least a part of the circumference of the sensor module 123, the sensor module 123 is located within the protection area 13, preventing the subject to be repelled from entering the protection area 13, thereby avoiding the sensor module 123 being blocked by the subject to be repelled or being affected by the mucus secreted by the subject to be repelled, which may cause problems such as inaccurate detection, and improving the detection accuracy and reliability of the charging device 200.

[0098] Further optionally, please refer to Figure 5 , the sensor module 123 is located on the side of the charging base 230 facing the parking area 220a. Specifically, the following embodiments are included:

[0099] The sensor module 123 is located on the side of the charging base 230 facing the parking area 220a. The sensor module 123 includes an infrared module 201, etc. The repelling device 40 is disposed around the side of the charging base 230 facing the parking area 220a and surrounds the circumference of the sensor module such as the infrared module 201 to effectively protect the infrared module 201, etc., from being blocked by the subject to be repelled or being affected by the mucus secreted by the subject to be repelled.

[0100] Optionally, please refer to Figure 5 , the at least one component to be protected 12 includes a charging component 202 (the aforementioned charging component 202). The repelling device 40 is disposed around at least a part of the circumference of the charging component 202. Among them, the charging component 202 includes, but is not limited to, a charging interface, charging electrodes, or charging terminals, etc.

[0101] In this embodiment, by arranging the repelling device 40 around the circumference of the charging component 202 such as the charging interface, charging electrodes, or charging terminals, the charging component 202 such as the charging interface, charging electrodes, or charging terminals is located within the protection area 13, preventing the subject to be repelled from entering the protection area 13, thereby avoiding the charging component 202 such as the charging interface, charging electrodes, or charging terminals being blocked by the subject to be repelled or being affected by the mucus secreted by the subject to be repelled, which may cause problems such as low charging efficiency, even inability to charge, or charging short circuit, etc., and improving the charging protection ability of the charging device 200.

[0102] Further optionally, please refer to Figure 5 , the charging component 202 is located on the side of the charging base 230 facing the parking area 220a. Specifically, the following embodiments are included:

[0103] Charging components 202 such as a charging interface, a charging electrode plate, or a charging terminal are located on one side of the charging base 230 facing the parking area 220a. The repelling device 40 is disposed around one side of the charging base 230 facing the parking area 220a and surrounds the charging components 202 such as the charging interface, the charging electrode plate, or the charging terminal, so as to effectively protect the charging components 202, prevent the charging components 202 such as the charging interface, the charging electrode plate, or the charging terminal from being blocked by the subject to be repelled or corroded by the mucus secreted by the subject to be repelled, and improve the charging protection ability of the charging device 200.

[0104] Optionally, the repelling device 40 is configured to generate a repelling current to repel the subject to be repelled.

[0105] In this embodiment, the subject to be repelled is, for example, a snail. When the snail crawls into contact with the repelling device 40, the microcurrent generated by the repelling device 40 will conduct to the body of the snail, causing the snail to feel a slight electric shock and discomfort, so as to change the crawling direction and move away from the area where the repelling device 40 is located (i.e., the protection area 13), achieving the purpose of repelling the snail and preventing the protected component 12 in the protection area 13 from being blocked by the snail or affected by the mucus secreted by the snail.

[0106] Optionally, the repelling current generated by the repelling device 40 is a microcurrent. The intensity of the repelling current generated by the repelling device 40 is less than the first preset current intensity. The first preset current intensity is 2 mA. The present application does not specifically limit the intensity of the repelling current generated by the repelling device 40. Optionally, the current range of the repelling current is a milliampere-level or microampere-level current, and this microcurrent will not pose a threat to the human body and will not cause fatal harm to the snail, but only makes the snail feel uncomfortable. For example, the current intensity of the repelling current can be, but is not limited to, any one of or any data between any two of 10 μA, 50 μA, 100 μA, 200 μA, 300 μA, 400 μA, 500 μA, 600 μA, 700 μA, 800 μA, 900 μA, 1 mA, etc.

[0107] The following embodiments illustrate the specific structure of the repelling device 40. Of course, the repelling device 40 provided in the present application includes, but is not limited to, the following embodiments.

[0108] In a first optional embodiment of the repelling device 40, please refer to Figure 6 The repelling device 40 includes a first electrode 41 and a second electrode 42.

[0109] Optionally, the arrangement of the first electrode 41 and the second electrode 42 includes, but is not limited to, parallel arrangement, non-parallel and non-intersecting arrangement, and intersecting but electrically isolated arrangement. In this embodiment, the parallel arrangement between the first electrode 41 and the second electrode 42 is taken as an example. In this embodiment, the extension direction of the first electrode 41 and the second electrode 42 is not specifically limited.

[0110] When the subject to be repelled contacts the first electrode 41 and the second electrode 42 at the same time, a conducting loop is formed between the first electrode 41, the subject to be repelled and the second electrode 42, and a repelling current is generated. The repelling current is a microcurrent, which is transmitted to the snail's body, causing the snail to receive a slight electric shock and feel uncomfortable, thereby changing the crawling direction and moving away from the area where the repelling device 40 is located (i.e., the protection area 13), thereby repelling the snail and preventing the protected component 12 in the protection area 13 from being blocked by the snail or affected by the mucus secreted by the snail.

[0111] Further optionally, the first electrode 41 is electrically connected to a positive electrode of a power source, and the second electrode 42 is electrically connected to a negative electrode of a power source.

[0112] The power source includes but is not limited to the power source of the charging device 200, or a micro power source formed by the power source of the charging device 200 providing a voltage, or a repelling power source provided by the repelling device 40. The power source will be described in detail with examples later.

[0113] In this embodiment, the first electrode 41 is a positive electrode, and the second electrode 42 is a negative electrode. In the initial state, the first electrode 41 and the second electrode 42 are in an open circuit state. When the subject to be repelled contacts the first electrode 41 and the second electrode 42 at the same time, the first electrode 41 and the second electrode 42 are electrically connected. Among them, a preset potential difference is formed between the first electrode 41 and the second electrode 42. When the subject to be repelled contacts the first electrode 41 and the second electrode 42 at the same time, a conductive loop is formed between the first electrode 41, the subject to be repelled and the second electrode 42, and a repelling current is generated, so that the subject to be repelled receives a slight electric shock and produces discomfort, thereby changing the crawling direction and moving away from the area where the repelling device 40 is located (i.e., the protection area 13).

[0114] Optionally, the distance between the first electrode 41 and the second electrode 42 is greater than or equal to a first preset distance, and less than or equal to a second preset distance.

[0115] For example, the first preset distance is 0.1 cm, and the second preset distance is 1 cm. If the distance between the first electrode 41 and the second electrode 42 is too large, it may cause some small snails to be unable to contact the first electrode 41 and the second electrode 42 simultaneously, resulting in the inability to form a conduction loop between the first electrode 41 and the second electrode 42. Some small snails will not generate a repelling current when passing through the repelling device 40, causing the repelling device 40 to be unable to prevent some small snails from blocking the component to be protected 12 or the mucus secreted by the snails from affecting the component to be protected 12.

[0116] If the distance between the first electrode 41 and the second electrode 42 is too small, it may cause the first electrode 41 and the second electrode 42 to be easily directly conducted, resulting in a short circuit.

[0117] Further for example, the first preset distance is 0.1 cm, and the second preset distance is 0.5 cm. Generally, the width of a snail is about 0.6 cm. By setting the distance between the first electrode 41 and the second electrode 42 to be greater than or equal to 0.1 cm and less than or equal to 0.5 cm, so that even if the snail crawls along the gap between the first electrode 41 and the second electrode 42, it will contact the first electrode 41 and the second electrode 42 simultaneously, thereby preventing the snail from crawling along the gap between the first electrode 41 and the second electrode 42, and the snail can be driven away from the repelling device 40 as early as possible, further reducing the probability of the snail entering the protection area 13 and improving the repelling rate for the snail.

[0118] The following embodiments of the present application will illustrate the shapes of the first electrode 41 and the second electrode 42 by way of example.

[0119] In the first optional embodiment of the electrode shape, please refer to Figure 6 , the first electrode 41 is an annular electrode. The second electrode 42 is an annular electrode.

[0120] Taking the first electrode 41 being annular and the second electrode 42 being annular as an example. Among them, the first electrode 41 is arranged around the circumference of the component to be protected 12 (specifically, it can be combined with the position design of the aforementioned repelling device 40).

[0121] Please refer to Figure 6 , the repelling device 40 further includes a first extension electrode 43. One end of the first extension electrode 43 is electrically connected to the first electrode 41, and the other end of the first extension electrode 43 is electrically connected to the positive electrode of the power supply. For example, the positive electrode of the power supply is located in the charging base 230, the first electrode 41 is arranged on the outer surface of the charging base 230, one end of the first extension electrode 43 contacts the outer surface of the charging base 230, and the other end enters the charging base 230 and extends to the position where the positive electrode of the power supply is located.

[0122] The first electrode 41 includes, but is not limited to, a metal trace, and the first extended electrode 43 includes, but is not limited to, a wire with a protective sleeve, etc.

[0123] The second electrode 42 is also disposed around the circumferential side of the component 12 to be protected (specifically, it can be designed in combination with the position of the repelling device 40 described above). In one embodiment, the second electrode 42 is located between the first electrode 41 and the component 12 to be protected. In other embodiments, the first electrode 41 is located between the second electrode 42 and the component 12 to be protected.

[0124] Please refer to Figure 6 , the repelling device 40 further includes a second extended electrode 44. One end of the second extended electrode 44 is electrically connected to the second electrode 42, and the other end of the second extended electrode 44 is electrically connected to the negative electrode of the power supply. For example, the negative electrode of the power supply is located inside the charging base 230, the second electrode 42 is disposed on the outer surface of the charging base 230, one end of the second extended electrode 44 contacts the outer surface of the charging base 230, and the other end enters the charging base 230 and extends to the position where the negative electrode of the power supply is located.

[0125] The second electrode 42 includes, but is not limited to, a metal trace, and the second extended electrode 44 includes, but is not limited to, a wire with a protective sleeve, etc.

[0126] In the second alternative embodiment of the electrode shape, please refer to Figure 7 , the first electrode 41 is a planar spiral electrode. The first electrode 41 is a first planar spiral electrode. One end of the first planar spiral electrode is electrically connected to the positive electrode of the power supply. The first planar spiral electrode is disposed around the circumferential side of the component 12 to be protected in a planar spiral shape, and the other end of the first planar spiral electrode is an open end.

[0127] The second electrode 42 is a planar spiral electrode. The second electrode 42 is a second planar spiral electrode. One end of the second planar spiral electrode is electrically connected to the negative electrode of the power supply. The second planar spiral electrode is disposed around the circumferential side of the component 12 to be protected in a planar spiral shape, and the other end of the second planar spiral electrode is an open end.

[0128] This application does not specifically limit the number of turns of the first planar spiral electrode and the number of turns of the second planar spiral electrode. Optionally, the first planar spiral electrode winds one turn, the second planar spiral electrode winds one turn, and the first planar spiral electrode and the second planar spiral electrode are arranged at intervals. A potential difference and an electrical stimulation protection are formed between the first planar spiral electrode and the second planar spiral electrode. Optionally, the first planar spiral electrode winds two turns, the second planar spiral electrode winds one turn, and the first turn of the first planar spiral electrode, the second planar spiral electrode, and the second turn of the first planar spiral electrode are arranged at intervals in sequence. A potential difference and a first electrical stimulation protection are formed between the first turn of the first planar spiral electrode and the second planar spiral electrode, and a potential difference and a second electrical stimulation protection are formed between the second planar spiral electrode and the second turn of the first planar spiral electrode.

[0129] In this embodiment, compared with the first optional electrode shape, it is not necessary to additionally provide the first extension electrode 43 and the second extension electrode 44, and the multi-turn positive electrodes and the multi-turn negative electrodes can be alternately arranged at intervals in sequence to form multiple electrical stimulation protections.

[0130] This application does not specifically limit the number of the first electrodes 41 and the number of the second electrodes 42.

[0131] Optionally, there is one first electrode 41 and one second electrode 42.

[0132] Taking the first electrode 41 being annular and the second electrode 42 being annular as an example. Among them, the first electrode 41 is arranged around the circumference of the component 12 to be protected (specifically, it can be combined with the position design of the aforementioned repelling device 40). The second electrode 42 is also arranged around the circumference of the component 12 to be protected (specifically, it can be combined with the position design of the aforementioned repelling device 40).

[0133] In one embodiment, the second electrode 42 is located between the first electrode 41 and the component 12 to be protected. In other embodiments, the first electrode 41 is located between the second electrode 42 and the component 12 to be protected. A potential difference exists between the first electrode 41 and the second electrode 42, and a first electrical stimulation protection is formed.

[0134] Optionally, please refer to Figure 8 , the first electrode 41 and the second electrode 42 each include a plurality. The number of the first electrodes 41 is a plurality, and the number of the second electrodes 42 is a plurality. The plurality of first electrodes 41 and the plurality of second electrodes 42 are alternately arranged at intervals. For example, the first electrode 41, the second electrode 42, the first electrode 41, the second electrode 42, the first electrode 41, the second electrode 42... are alternately arranged in sequence.

[0135] Taking the example where the first electrode 41 is annular and the second electrode 42 is annular. The multiple first electrodes 41 are annular electrodes with multiple different radial dimensions. The multiple second electrodes 42 are annular electrodes with multiple radial dimensions. The first electrode 41, the second electrode 42, the first electrode 41, and the second electrode 42 are alternately arranged in sequence. In this way, a potential difference is formed between every two adjacent electrodes to form an electric stimulation protection outside the protection area 13. This embodiment can form multiple electric stimulation protections outside the protection area 13 to prevent the subject to be repelled from directly entering the protection area 13 after passing through the first electric stimulation protection. Even if the subject to be repelled passes through the first electric stimulation protection and then continues to move towards the protection area 13, it will encounter the next electric stimulation protection, thereby causing the subject to be repelled to move away from the protection area 13, improving the repelling rate of the subject to be repelled.

[0136] In other embodiments, the arrangement of the multiple first electrodes 41 and the multiple second electrodes 42 may also be in the pattern of the first electrode 41, the second electrode 42, the second electrode 42, the first electrode 41, the first electrode 41... In some cases, due to some gaps between the subject to be repelled and the surface of the charging base 230, the first electrode 41 or the second electrode 42 is not contacted, resulting in non-conduction between the first electrode 41 and the second electrode 42 and the inability to generate a repelling current. By arranging two (or more) first electrodes 41 and two (or more) second electrodes 42 alternately in sequence in this embodiment, even when there are some gaps between the subject to be repelled and the surface of the charging base 230, the probability of the subject to be repelled contacting the first electrode 41 or the second electrode 42 can be increased, thereby increasing the probability of generating a repelling current when encountering the subject to be repelled and increasing the interception rate of the subject to be repelled.

[0137] Optionally, please refer to Figure 8 , the voltages of the multiple first electrodes 41 are the same, and the voltages of the multiple second electrodes 42 are the same. That is, the multiple first electrodes 41 are all electrically connected to the positive electrode of the power supply, and the multiple second electrodes 42 are all electrically connected to the negative electrode of the power supply.

[0138] Further optionally, please refer to Figure 8, the repelling device 40 further includes a first extension electrode 43. The first extension electrode 43 intersects with and is electrically connected to a plurality of first electrodes 41, and the first extension electrode 43 intersects with a plurality of second electrodes 42 and is electrically insulated therefrom. A part of the first extension electrode 43 is electrically connected to a plurality of first electrodes 41, and another part of the first extension electrode 43 is electrically connected to the positive electrode of the power supply. For example, the positive electrode of the power supply is located inside the charging base 230, the first electrodes 41 are provided on the outer surface of the charging base 230, a part of the first extension electrode 43 contacts the outer surface of the charging base 230, the first electrodes 41 include but are not limited to metal traces, and a part of the first extension electrode 43 is a metal trace. Another part of the first extension electrode 43 enters the charging base 230 and extends to the position where the positive electrode of the power supply is located. Another part of the first extension electrode 43 includes but is not limited to a wire with a protective sleeve, etc.

[0139] In this embodiment, a plurality of first electrodes 41 can be electrically connected to the positive electrode of the power supply through the same first extension electrode 43. Compared with each first electrode 41 being electrically connected to the positive electrode of the power supply through an electrical connection trace, the number of electrical connection traces can be reduced, and the layout of the electrical connection traces can be optimized.

[0140] Further optionally, please refer to Figure 8 , the repelling device 40 further includes a second extension electrode 44. The second extension electrode 44 intersects with and is electrically connected to a plurality of second electrodes 42, and the second extension electrode 44 intersects with a plurality of second electrodes 42 and is electrically insulated therefrom. A part of the second extension electrode 44 is electrically connected to a plurality of second electrodes 42, and another part of the second extension electrode 44 is electrically connected to the negative electrode of the power supply. For example, the negative electrode of the power supply is located inside the charging base 230, the second electrodes 42 are provided on the outer surface of the charging base 230, a part of the second extension electrode 44 contacts the outer surface of the charging base 230, the second electrodes 42 include but are not limited to metal traces, and a part of the second extension electrode 44 is a metal trace. Another part of the second extension electrode 44 enters the charging base 230 and extends to the position where the negative electrode of the power supply is located. Another part of the second extension electrode 44 includes but is not limited to a wire with a protective sleeve, etc.

[0141] In this embodiment, a plurality of second electrodes 42 can be electrically connected to the negative electrode of the power supply through the same second extension electrode 44. Compared with each second electrode 42 being electrically connected to the negative electrode of the power supply through an electrical connection trace, the number of electrical connection traces can be reduced, and the layout of the electrical connection traces can be optimized.

[0142] In other embodiments, the voltages of the plurality of first electrodes 41 may be different. The plurality of first electrodes 41 are respectively electrically connected to different positive power output ports to apply different positive voltages. The plurality of second electrodes 42 are all electrically connected to the negative power electrode. The first electrodes 41 and the second electrodes 42 are alternately arranged to form an electrical stimulation protection with different potential differences. For example, the voltage difference formed between the first first electrode 41 and the first second electrode 42 is the first voltage, and the potential difference formed between the first second electrode 42 and the second second electrode 42 is the second voltage. Among them, the second voltage may be greater than the first voltage. In this way, even if some large objects to be repelled pass through the first electrical stimulation protection with the first voltage, if they continue to move forward towards the protection area 13, they will be subjected to the second electrical stimulation protection with a greater voltage (the second voltage), and so on, until some large objects to be repelled change direction under the electrical stimulation and move away from the protection area 13. The design of the repelling device 40 in this embodiment can not only repel small objects to be repelled, but also repel large objects to be repelled, increasing the interception rate of the objects to be repelled and improving the protection rate of the objects to be protected.

[0143] In the second alternative embodiment of the repelling device 40, this embodiment is substantially the same as the first alternative embodiment. The main difference between this embodiment and the first alternative embodiment is as follows. Please refer to Figure 9 , the first electrode 41 and the second electrode 42 are respectively electrically connected to two positive electrode voltage output terminals of the power supply. There is a potential difference between the two positive electrode voltage output terminals.

[0144] For example, the two positive electrode voltage output terminals of the power supply respectively include a first voltage output terminal and a second voltage output terminal. The first voltage output terminal outputs the first voltage, and the second voltage output terminal outputs the second voltage. The first electrode 41 is electrically connected to the first voltage output terminal to apply the first voltage. The second electrode 42 is electrically connected to the second voltage output terminal to apply the second voltage. The first voltage is different from the second voltage, that is, there is a voltage difference between the first electrode 41 and the second electrode 42. In the initial state, the first electrode 41 and the second electrode 42 are in an open circuit state. When the object to be repelled contacts the first electrode 41 and the second electrode 42 at the same time, the first electrode 41 and the second electrode 42 are electrically conducted. Since there is a voltage difference between the first electrode 41 and the second electrode 42, a conduction loop is formed among the first electrode 41, the object to be repelled, and the second electrode 42, and a repelling current is generated, causing the object to be repelled to feel a slight electric shock and discomfort, so as to change the crawling direction and move away from the area where the repelling device 40 is located (i.e., the protection area 13).

[0145] In this embodiment, since the intensity of the repelling current is small, for example, the repelling current is about several hundred microamperes, based on this, the voltage difference between the first electrode 41 and the second electrode 42 is also small. In this embodiment, by forming the first electrode 41 and the second electrode 42 with a small voltage difference, a small voltage difference is formed, and then a minute repelling current is formed.

[0146] Among them, the shape of the first electrode 41 and the electrical connection mode between the first electrode 41 and the first voltage output terminal of the power supply can refer to the shape of the first electrode 41 and the electrical connection mode between the first electrode 41 and the positive electrode of the power supply in the first embodiment.

[0147] Among them, the shape of the second electrode 42 and the electrical connection mode between the second electrode 42 and the second voltage output terminal of the power supply can refer to the shape of the second electrode 42 and the electrical connection mode between the second electrode 42 and the positive electrode of the power supply in the first embodiment.

[0148] The number of the first electrodes 41 can be one or more, and the number of the second electrodes 42 can be one or more. When there are multiple first electrodes 41 and second electrodes 42, the first electrodes 41 and the second electrodes 42 can be arranged alternately in sequence.

[0149] In the third optional embodiment of the repelling device 40, this embodiment is substantially the same as the second optional embodiment. The difference from the second optional embodiment is that in this embodiment, please refer to Figure 10 , the repelling device 40 further includes a plurality of third electrodes 45. The plurality of third electrodes 45 are located between the first electrode 41 and the second electrode 42.

[0150] Further, a first potential difference is formed between the third electrode 45 and the first electrode 41. A second potential difference is formed between the third electrode 45 and the second electrode 42. The first potential difference is different from the second potential difference.

[0151] Specifically, the three positive electrode voltage output terminals of the power supply respectively include a first voltage output terminal, a second voltage output terminal, and a third voltage output terminal. The first voltage output terminal outputs a first voltage, the second voltage output terminal outputs a second voltage, and the third voltage output terminal outputs a third voltage.

[0152] The first electrode 41 is electrically connected to the first voltage output terminal to load the first voltage. The second electrode 42 is electrically connected to the second voltage output terminal to load the second voltage. The third electrode 45 is electrically connected to the third voltage output terminal to load the third voltage.

[0153] The first voltage is different from the third voltage, that is, there is a first potential difference between the first electrode 41 and the third electrode 45.

[0154] The third voltage is different from the second voltage, that is, there is a second potential difference between the third electrode 45 and the second electrode 42.

[0155] In the initial state, there is an open circuit between the first electrode 41 and the third electrode 45. When the subject to be repelled contacts the first electrode 41 and the third electrode 45 simultaneously, the first electrode 41 and the third electrode 45 are electrically connected. Since there is a first potential difference between the first electrode 41 and the third electrode 45, a conduction loop is formed among the first electrode 41, the subject to be repelled, and the third electrode 45, and a first repelling current is generated, causing the subject to be repelled to feel a slight electric shock and discomfort, thereby changing the crawling direction and moving away from the area where the repelling device 40 is located (i.e., the protection area 13).

[0156] Furthermore, the second potential difference can be greater than the first potential difference. In this way, the repelling current generated when the third electrode 45 and the second electrode 42 are conducting is greater than the repelling current generated when the first electrode 41 and the third electrode 45 are conducting, thereby further electrically stimulating the subject to be repelled to make the subject to be repelled move away from the protection area 13; or further electrically stimulating a larger subject to be repelled to make the larger subject to be repelled move away from the protection area 13.

[0157] The first electrode 41 is located on a side away from the component to be protected 12. The second electrode 42 is located on a side close to the component to be protected 12. If the subject to be repelled crosses the first electrical stimulation protection between the first electrode 41 and the third electrode 45, in the initial state, there is an open circuit between the third electrode 45 and the second electrode 42. When the subject to be repelled contacts the third electrode 45 and the second electrode 42 simultaneously, the third electrode 45 and the second electrode 42 are electrically connected. Since there is a second potential difference between the third electrode 45 and the second electrode 42, a conduction loop is formed among the third electrode 45, the subject to be repelled, and the second electrode 42, and a second repelling current is generated. The second repelling current is greater than the first repelling current, causing the subject to be repelled to feel further electrical stimulation and discomfort, thereby changing the crawling direction and moving away from the area where the repelling device 40 is located (i.e., the protection area 13).

[0158] Further optionally, in the direction from the first electrode 41 towards the second electrode 42, the potential difference between two adjacent third electrodes 45 increases successively. In this way, in the direction from the first electrode 41 towards the second electrode 42, the intensity of the repelling current of the electrical stimulation protection formed between two adjacent third electrodes 45 gradually increases.

[0159] On the one hand, as the subject to be repelled crawls closer to the protection area 13, the electric stimulation it needs to bear gradually increases, so as to drive some larger subjects to be repelled to crawl away from the protection area 13; on the other hand, some larger subjects to be repelled can simultaneously contact the first electrode 41 and multiple third electrodes 45, that is, they are simultaneously subjected to the repelling current brought by multiple electric stimulation protections, and thus can further stimulate the larger subjects to be repelled to crawl away from the protection area 13.

[0160] In a fourth alternative embodiment of the repelling device 40, please refer to Figure 11 , the first electrode 41 and the second electrode 42 each include a plurality. The number of the first electrodes 41 is multiple, and the number of the second electrodes 42 is multiple. The multiple first electrodes 41 are arranged at intervals in sequence. The multiple second electrodes 42 are arranged at intervals in sequence. Among them, the extending direction of the first electrode 41 is the first direction, and adjacent two first electrodes 41 can be arranged in parallel, or not parallel and not intersecting. Among them, the extending direction of the second electrode 42 is the second direction, and adjacent two second electrodes 42 can be arranged in parallel, or not parallel and not intersecting. The first direction intersects the second direction.

[0161] The multiple first electrodes 41 and the multiple second electrodes 42 are crisscrossed to form a grid-shaped repelling device 40. The grid-shaped repelling device 40 can increase the probability that the subjects to be repelled from different crawling directions simultaneously contact two electrodes with a voltage difference, thereby generating a repelling current, and further repelling the subjects to be repelled in different crawling directions.

[0162] Optionally, please refer to Figure 11 , the multiple first electrodes 41 include a first positive electrode 411 and a first negative electrode 412 arranged alternately. Optionally, the first positive electrode 411 extends along the first direction, and the first negative electrode 412 extends along the first direction. The multiple first positive electrodes 411 and the multiple first negative electrodes 412 are arranged alternately in sequence.

[0163] Please refer to Figure 11 , the multiple second electrodes 42 include a second positive electrode 421 and a second negative electrode 422 arranged alternately. Optionally, the second positive electrode 421 extends along the second direction, and the second negative electrode 422 extends along the second direction. The multiple second positive electrodes 421 and the multiple second negative electrodes 422 are arranged alternately in sequence.

[0164] Furthermore, the first positive electrode 411 and the second negative electrode 422 are electrically isolated at their intersection. That is, the first positive electrode 411 and the second negative electrode 422 are electrically insulated at their intersection. Furthermore, the first positive electrode 411 and the second negative electrode 422 are insulated and connected through a first insulating part at the intersection.

[0165] The first negative electrode 412 and the second positive electrode 421 are electrically isolated at their intersection. That is, the first negative electrode 412 and the second positive electrode 421 are electrically insulated at their intersection. Further, the first negative electrode 412 and the second positive electrode 421 are insulatingly connected at the intersection through a second insulating portion.

[0166] For example, the first positive electrode 411 is annular and surrounds the circumference of the component 12 to be protected, and the first negative electrode 412 is also annular and surrounds the circumference of the component 12 to be protected. The first first positive electrode 411, the first first negative electrode 412, the second first positive electrode 411, and the second first negative electrode 412 are distributed in sequence from outside to inside.

[0167] There is a potential difference between the first positive electrode 411 and the first negative electrode 412. In the initial state, the first positive electrode 411 and the first negative electrode 412 are in an open circuit state. When the main body to be repelled contacts the first positive electrode 411 and the first negative electrode 412 simultaneously, the first positive electrode 411 and the first negative electrode 412 are electrically conducted. Due to the pressure difference between the first positive electrode 411 and the first negative electrode 412, a conduction loop is formed among the first positive electrode 411, the main body to be repelled, and the first negative electrode 412, and a repelling current is generated, causing the main body to be repelled to receive a slight electric shock and feel discomfort, thereby changing the crawling direction and moving away from the area where the repelling device 40 is located (i.e., the protection area 13).

[0168] The first positive electrode 411 in this embodiment can refer to the first electrode 41 in the first embodiment, and the first negative electrode 412 in this embodiment can refer to the second electrode 42 in the first embodiment.

[0169] In a further optional embodiment, please refer to Figure 11 , the second positive electrode 421 extends along the radial direction of the ring, and the second negative electrode 422 extends along the radial direction of the ring. In other embodiments, the second positive electrode 421 can also extend in other directions intersecting with the first negative electrode 412.

[0170] Each second positive electrode 421 intersects with a plurality of first positive electrodes 411 and a plurality of first negative electrodes 412. Further, each of the first positive electrodes 411 and the second positive electrode 421 is electrically connected at their intersection. In this way, the first positive electrode 411 and the second positive electrode 421 are loaded with the same positive voltage. In this way, a plurality of first positive electrodes 411 and a plurality of second positive electrodes 421 can be electrically connected to the positive electrode of the power supply through the same electrical connection trace. The second positive electrode 421 and the first negative electrode 412 are electrically insulated at their intersection to avoid forming a short circuit.

[0171] Each second negative electrode 422 intersects with a plurality of first negative electrodes 412 and a plurality of first positive electrodes 411. Further, the second negative electrode 422 is electrically connected to the first negative electrode 412 at the intersection of the two. In this way, the plurality of first negative electrodes 412 and the plurality of second negative electrodes 422 can be electrically connected to the negative electrode of the power supply through the same electrical connection trace. The second negative electrode 422 is electrically insulated from the first positive electrode 411 at the intersection of the two to avoid short circuit.

[0172] When the subject to be repelled crawls towards the protection area 13 along the annular radial direction or a direction intersecting the annular radial direction, the subject to be repelled will simultaneously contact the positive and negative electrodes, thereby generating a repelling current. The subject to be repelled will change its crawling direction under the electrical stimulation of the repelling current until it crawls towards an area outside the repelling device 40, thereby effectively preventing the subject to be repelled from different directions from entering the protection area 13.

[0173] In a fifth optional embodiment of the repelling device 40, this embodiment is similar to the fourth optional embodiment. The difference is that, please refer to Figure 12 , in this embodiment, the plurality of first electrodes 41 include a plurality of third positive electrodes 413. The plurality of second electrodes 42 include a plurality of fourth positive electrodes 423. The intersections of each third positive electrode 413 and each fourth positive electrode 423 are electrically isolated.

[0174] In an optional embodiment, the voltages applied to the plurality of third positive electrodes 413 are the same. The voltages applied to the plurality of fourth positive electrodes 423 are the same, and the voltages applied to the third positive electrodes 413 and the fourth positive electrodes 423 are different. In this way, two intersecting grid-shaped electrode protection nets with a potential difference are formed.

[0175] In another optional embodiment, the voltages applied to the plurality of third positive electrodes 413 are different.

[0176] For example, in the direction gradually approaching the component to be protected 12, the potential difference between two adjacent third positive electrodes 413 gradually increases. Further for example, the third positive electrodes 413 are annular. The plurality of third positive electrodes 413 are sequentially arranged around the circumference of the component to be protected 12.

[0177] In this embodiment, in the direction gradually approaching the component to be protected 12, the intensity of the repelling current for the electrical stimulation protection formed between two adjacent third positive electrodes 413 gradually increases.

[0178] On the one hand, as the subject to be repelled crawls closer to the protection area 13, the electric stimulation it needs to bear gradually increases, so as to drive some larger subjects to be repelled to crawl away from the protection area 13; on the other hand, some larger subjects to be repelled can contact multiple third positive electrodes 413 at the same time, that is, they are simultaneously subjected to the repelling current brought by multiple electric stimulation protections, and further stimulate the larger subjects to be repelled to crawl away from the protection area 13.

[0179] In this embodiment, since the intensity of the repelling current is small, for example, the repelling current is about several hundred microamperes. Based on this, the potential difference between two adjacent third positive electrodes 413 is also small. In this embodiment, two voltages with a small difference are respectively applied to the two third positive electrodes 413 to form a small potential difference, which is more likely to form a small repelling current.

[0180] Further optionally, please refer to Figure 13 , the voltages applied to the multiple fourth positive electrodes 423 are different.

[0181] For example, the extending direction of the multiple fourth positive electrodes 423 is the radial direction of the annular third positive electrode 413. Each fourth positive electrode 423 intersects with multiple third positive electrodes 413 and is electrically connected through a third insulating part at the intersection.

[0182] In this embodiment, for a group of fourth positive electrodes 423, the intensity of the repelling current formed by the electric stimulation protection between two adjacent fourth positive electrodes 423 gradually increases. Multiple groups of fourth positive electrodes 423 are arranged in sequence. For example, in the circumferential direction around the component 12 to be protected, the current distribution of multiple groups of fourth positive electrodes 423 is: V1, V2, V3, V4, V5, V1, V2, V3, V4, V5, V1, V2, V3, V4, V5, V1, V2, V3, V4, V5,... V1, V2, V3, V4, V5. Among them, V1, V2, V3, V4, V5 are a group of fourth positive electrodes 423.

[0183] On the one hand, as the subject to be repelled crawls closer to the protection area 13, the electric stimulation it needs to bear gradually increases, so as to drive some larger subjects to be repelled to crawl away from the protection area 13; on the other hand, some larger subjects to be repelled can contact multiple fourth positive electrodes 423 at the same time, that is, they are simultaneously subjected to the repelling current brought by multiple electric stimulation protections, and further stimulate the larger subjects to be repelled to crawl away from the protection area 13.

[0184] In this embodiment, since the intensity of the repelling current is small, for example, the repelling current is about several hundred microamperes. Based on this, the potential difference between two adjacent fourth positive electrodes 423 is also small. In this embodiment, two voltages with a small difference are respectively applied to the two fourth positive electrodes 423 to form a small potential difference, making it easier to form a tiny repelling current.

[0185] The grid-shaped repelling device 40 protection net formed above can form electrode lines with potential differences in all directions, thereby effectively preventing the subjects to be repelled from different directions from entering the protection area 13.

[0186] Further optionally, the voltage of each fourth positive electrode 423 is the same as that of a third positive electrode 413, and they are electrically connected at the intersection. For example, the voltages of five third positive electrodes 413 are: V1, V2, V3, V4, V5 in sequence; the voltages of a group of fourth positive electrodes 423 are: V1, V2, V3, V4, V5 in sequence. In this way, multiple fourth positive electrodes 423 with the same voltage can be electrically connected through a third positive electrode 413 and form electrodes with the same voltage, and are electrically connected to a positive electrode output port of the power supply through one electrical connection trace.

[0187] The surface of the first electrode 41 is flush with the surface of the charging base 230 or protrudes from the surface of the charging base 230, so as to facilitate the full contact between the first electrode 41 and the subject to be repelled.

[0188] The surface of the second electrode 42 is flush with the surface of the charging base 230 or protrudes from the surface of the charging base 230, so as to facilitate the full contact between the second electrode 42 and the subject to be repelled.

[0189] Further optionally, please refer to Figure 14 , the second electrode 42 protrudes relative to the first electrode 41. Among them, because the snail is a soft-bodied organism, when the snail passes through the first electrode 41 and the second electrode 42, it touches the first electrode 41 and the second electrode 42 at the same time, thereby forming a conduction loop between the first electrode 41 and the second electrode 42 and generating a repelling current. And the first electrode 41 and the second electrode 42 are arranged in a high-low staggered manner, so that the user's finger will not touch the first electrode 41 and the second electrode 42 at the same time, preventing the user from accidentally touching the first electrode 41 and the second electrode 42.

[0190] Furthermore, the number of the first electrodes 41 is multiple, the number of the second electrodes 42 is multiple, and the distance between two adjacent second electrodes 42 is less than or equal to a first preset distance. Among them, the first preset distance is less than the width of the user's little finger pulp, so that the user's finger pulp will not touch the first electrode 41 and the second electrode 42 at the same time. For example, the first preset distance is 4 mm.

[0191] Optionally, please refer toFigure 15 A plurality of spaced-apart conductive portions 425 are provided on the second electrode 42. The plurality of conductive portions 425 are respectively electrically connected to the second electrode 42 and protrude relative to the first electrode 41.

[0192] Among them, since the snail is a soft-bodied organism, when the snail passes through the first electrode 41 and the second electrode 42, it simultaneously contacts the first electrode 41 and the second electrode 42, thereby forming a conduction loop between the first electrode 41 and the second electrode 42 and generating a repellent current. The first electrode 41 and the second electrode 42 are arranged with a vertical offset, so that the user's finger will not simultaneously contact the first electrode 41 and the second electrode 42, preventing the user from accidentally touching the first electrode 41 and the second electrode 42.

[0193] There is a gap between two adjacent conductive portions 425. When the second electrode 42 is annular and the number of the second electrodes 42 is multiple, the second electrode 42 protrudes above the plurality of conductive portions 425, which can effectively prevent the user from accidentally touching the first electrode 41 and the second electrode 42 at the same time, and can also facilitate the water between the two second electrodes 42 to flow out through the gap, avoiding water accumulation between two adjacent second electrodes 42 and causing problems such as short circuit between the first electrode 41 and the second electrode 42. Among them, the width of the gap between two adjacent conductive portions 425 is smaller than the width of the pulp of the little finger to prevent the finger from simultaneously contacting the first electrode 41 and the second electrode 42 (or the conductive portion 425).

[0194] Further optionally, the conductive portions 425 of two adjacent second electrodes 42 are arranged staggeredly. For example, the conductive portion 425 of the inner second electrode 42 is aligned with the gap of the outer second electrode 42, and the conductive portion 425 of the outer second electrode 42 is aligned with the gap of the inner second electrode 42, which can further effectively prevent the user from accidentally touching the first electrode 41 and the second electrode 42 at the same time, and can also facilitate the water between the two second electrodes 42 to flow out through the gaps on both sides, further avoiding water accumulation between two adjacent second electrodes 42 and causing problems such as short circuit between the first electrode 41 and the second electrode 42.

[0195] In a sixth optional embodiment of the repellent device 40, please refer to Figure 16 , the repellent device 40 includes a primary battery electrode 46. When the subject to be repelled contacts the primary battery electrode 46, a repellent current is generated through the primary battery effect to apply an electrical stimulus to the subject to be repelled.

[0196] The primary battery electrode 46 is a metal layer with electrochemical activity. This metal layer can undergo an electrochemical reaction with the mucus secreted by the snail to form a primary battery reaction. A current will be generated during the primary battery reaction, and this current can be conducted to the snail's body to generate a slight electrical stimulus to it, making the snail feel uncomfortable and stop moving or change its moving direction.

[0197] The materials of the primary battery electrode 46 include, but are not limited to, active metals such as copper, zinc, magnesium, and aluminum.

[0198] For example, the primary battery electrode 46 is a copper layer or a copper sheet. The primary battery electrode 46 is arranged around the component 12 to be protected. Optionally, the primary battery electrode 46 is in a closed ring shape or in multiple arc shapes. Generally, the gap between adjacent arc shapes is less than or equal to 5 mm to prevent snails from crawling into the protected area 13 through the gap between adjacent arc shapes. Of course, the primary battery electrode 46 can also be in a dot matrix shape. The gap between the dot matrix shapes is less than or equal to 5 mm to prevent snails from crawling into the protected area 13 through the gap between the dot matrix shapes.

[0199] It should be noted that the mucus secreted by snails contains water and a certain concentration of electrolytes (such as salts, calcium ions, and other minerals), which has electrical conductivity. When a snail crawls onto the copper surface, the mucus acts as a conductive medium, forming a simple electrochemical cell between the copper and the environment.

[0200] When the mucus of the snail comes into contact with the copper surface, the metal atoms in the copper will release electrons and be oxidized into copper ions (Cu2+). This process can react with the mucus in the snail's body to form a weak current. The specific anodic reaction formula of the primary battery (copper is oxidized) is as follows:

[0201] Cu→Cu 2+ +2e -

[0202] The specific cathodic reaction formula of the primary battery is as follows:

[0203] O 2- +4H + +4e - →2H 2 O

[0204] These reactions form a closed circuit with the help of the mucus, resulting in the generation of a tiny current. This current has a stimulating effect on the snail's body, which may interfere with the snail's nervous system or metabolic process. In addition, the generated copper ions (Cu2+) prompt the snail to avoid the copper surface.

[0205] The repelling device 40 provided in this embodiment does not need to be provided with a power source, is a passive repelling device 40, saves energy consumption; and does not require electric control and will not pose a risk to users.

[0206] In the seventh optional embodiment of the repelling device 40, please refer to Figure 17 , the repelling device 40 includes a conductive layer 47. Both ends of the conductive layer 47 are electrically connected to the positive and negative electrodes of the power source respectively, and are used to apply an electric stimulus to the main body to be repelled when it comes into contact with the conductive layer 47.

[0207] Optionally, the conductive layer 47 is electrically connected to the conduction loop, so that a weak repelling current exists on the conductive layer 47. The conductive layer 47 is substantially annular and surrounds the circumferential side of the component 12 to be protected.

[0208] Specifically, the power supply, the load, and the conductive layer 47 form a conduction loop. The conductive layer 47 is disposed on the surface of the charging base 230 and is substantially annular, and is disposed on the circumferential side of the component 12 to be protected. Among them, the resistance value of the load is large, so that a small repelling current is formed in the conduction loop, so that the subject to be repelled stops moving or changes the moving direction when contacting the conductive layer 47, preventing the subject to be repelled from entering the protection area 13, and further preventing the component 12 to be protected from being blocked by the subject to be repelled or being affected by the mucus secreted by the subject to be repelled, so that the self-moving device 100 has a good repelling function and self-protection function, improving the reliability of the self-moving device 100.

[0209] The following embodiments illustrate the power supply of the repelling device 40 by way of example.

[0210] In the first optional embodiment of the power supply, the repelling device 40 further includes a first power supply. The positive electrode of the first power supply is electrically connected to the first electrode 41. The negative electrode of the first power supply is electrically connected to the second electrode 42, so that the first electrode 41 and the second electrode 42 are conducted through the subject to be repelled to generate a repelling current.

[0211] Further optionally, the first electrode 41 and the second electrode 42 are spaced apart or electrically insulated to form a plurality of annular electrodes, or spiral electrodes, or grid electrodes.

[0212] In this embodiment, the repelling device 40 independently sets a first power supply and does not need to share the power supply of the charging device 200. Furthermore, it is not necessary to convert the power supply of the charging device 200 into a corresponding small voltage to form a small repelling current.

[0213] Further optionally, the first power supply includes, but is not limited to, a solar cell. On the one hand, setting a solar cell can utilize solar energy for charging without using the power supply of the charging device 200; on the other hand, since the generated repelling current is very small, the required battery capacity is also very small, and solar charging is sufficient to supply the generated repelling current.

[0214] The second optional implementation of the power supply. The charging device 200 includes a second power supply. The positive electrode of the second power supply is electrically connected to the first electrode 41. The negative electrode of the second power supply is electrically connected to the second electrode 42, so that the first electrode 41 and the second electrode 42 are conducted through the main body to be repelled to generate a repelling current. Optionally, the second power supply can be a battery of the charging device 200, etc. In this implementation, the repelling device 40 reuses the charging battery of the charging device 200, without the need to additionally set up a power supply, saving costs and reducing the space required for additionally setting up a power supply, etc.

[0215] Further optionally, the charging component 202 includes a positive output electrode plate and a negative output electrode plate. The positive output electrode plate and the negative output electrode plate are respectively electrically connected to the positive electrode and the negative electrode of the second power supply of the charging device 200.

[0216] In an optional implementation, the charging device 200 further includes a control switch and a high-resistance voltage-dividing circuit. One end of the control switch is electrically connected to the positive output electrode plate, the other end of the control switch is electrically connected to one end of the high-resistance voltage-dividing circuit, the other end of the high-resistance voltage-dividing circuit is electrically connected to the first electrode 41, and the second electrode 42 is electrically connected to the negative output electrode plate. In this implementation, the high-resistance voltage-dividing circuit is used for series voltage division, so that the potential difference between the first electrode 41 and the second electrode 42 is small, and then the aforementioned tiny repelling current is formed. Further, a constant current source can also be connected in series in the circuit provided in this implementation to provide a relatively high-precision repelling current.

[0217] In another optional implementation, the charging device 200 further includes a control switch and a multi-stage step-down circuit. One end of the control switch is electrically connected to the positive output electrode plate, the other end of the control switch and the negative output electrode plate are respectively electrically connected to two input ends of the multi-stage voltage-dividing circuit, one output end of the multi-stage voltage-dividing circuit is electrically connected to the first electrode 41, and the other output end of the multi-stage voltage-dividing circuit is electrically connected to the second electrode 42. In this implementation, the multi-stage voltage-dividing circuit is used to step down the voltage provided by the second power supply first, so that the output voltage of the multi-stage step-down circuit is small, and then the potential difference between the first electrode 41 and the second electrode 42 is small, and then the aforementioned tiny repelling current is formed. Further, a constant current source can also be connected in series in the circuit provided in this implementation to provide a relatively high-precision repelling current.

[0218] In the eighth optional implementation of the repelling device 40, please refer to Figure 18 , the repelling device 40 includes a spiked structure 50. The spiked structure 50 protrudes from at least part of the circumference of the chassis 220, or protrudes from at least part of the circumference of the component 12 to be protected.

[0219] Optionally, the material of the spike structure 50 can be an insulating material. The spike structure 50 can be annular, or in a dot matrix, etc., surrounding the circumference of the component 12 to be protected. The spike structure 50 can repel snails by means of physical defense, preventing the component 12 to be protected within the protection area 13 from being blocked by snails or being affected by the mucus secreted by the snails.

[0220] Optionally, the material of the spike structure 50 can be a conductive material. When the spike structure 50 is made of a conductive material, the spike structure 50 can have the same structure as the primary battery electrode 46 in the sixth alternative embodiment, that is, a plurality of spike structures 50 are provided on the primary battery electrode 46. This embodiment uses the electric stimulation method of the primary battery effect and the physical defense method to repel snails, preventing the component 12 to be protected within the protection area 13 from being blocked by snails or being affected by the mucus secreted by the snails.

[0221] This application does not specifically limit the way the repelling device 40 is provided on the charging base 230.

[0222] Optionally, the repelling device 40 can be coated or printed on the charging base 230.

[0223] Optionally, the repelling device 40 can be pasted on the charging base 230 through an adhesive layer.

[0224] Optionally, the repelling device 40 is detachably connected to the charging base 230. The detachable connection of the repelling device 40 to the charging base 230 enables users or maintenance personnel to easily remove the repelling device 40 for cleaning, maintenance, or replacement, avoiding the impact on the overall use of the device due to damage to the protection device, and improving the maintainability and service life of the device. Further specifically, the repelling device 40 can be detachably connected to the charging base 230 by means of magnetic attraction or the like.

[0225] Further optionally, the surface of the charging base 230 is provided with a receiving groove. The receiving groove is generally annular. The receiving groove provides an accurate installation position for the repelling device 40, making it not easy to shift or loosen after being fitted, ensuring a more stable connection between the repelling device 40 and the charging base 230, and reducing the risk of displacement caused by vibration or external force. The repelling device 40 is partially or entirely embedded in the receiving groove, making it flush with the surface of the charging base 230 or forming a smooth transition, enhancing the integrity and aesthetics of the device appearance, and avoiding abrupt protrusions or gaps. The side wall of the receiving groove can limit and protect the repelling device 40, reducing the direct impact of external shocks or foreign objects on the edge of the repelling device 40 and reducing the possibility of its deformation or damage, thereby improving the durability of the protection device. By partially embedding the repelling device 40 in the receiving groove, the overall thickness or volume of the device can be reduced, achieving a more compact structural design. The repelling device 40 includes a mounting portion. The mounting portion is embedded in the receiving groove and at least partially protrudes from the surface of the charging base 230.

[0226] The installation part includes, but is not limited to, an insulating board. The repelling device 40 is made of a conductive material, such as a first electrode 41 and a second electrode 42; or a primary battery electrode 46. The repelling device 40 is disposed on the insulating board and is installed in the accommodating groove through the insulating board.

[0227] In this embodiment, an accommodating groove is provided to facilitate the installation of the repelling device 40.

[0228] In other embodiments, the surface of the charging base 230 may not be provided with an accommodating groove.

[0229] Optionally, the charging device 200 further includes a controller.

[0230] In an alternative embodiment, the component to be protected 12 includes a humidity sensor. The humidity sensor is electrically connected to the controller. The controller is at least used to control the repelling device 40 to be electrically connected to the power supply when the humidity sensor detects that the humidity is greater than or equal to a humidity threshold.

[0231] Specifically, generally because snails usually appear on rainy days, by providing a humidity sensor on the lawn mower, the humidity of the environment or the surface of the lawn mower is detected by the humidity sensor, and according to the humidity detection result, the repelling device 40 is controlled to be electrically conducted with the power supply to repel snails.

[0232] Optionally, the humidity threshold is not specifically limited. The humidity threshold includes, but is not limited to, 70%, 75%, or 80%, etc.

[0233] In this embodiment, according to the humidity detected by the humidity sensor, when the humidity is greater than the humidity threshold, the controller controls the power supply to supply power to the repelling device 40, so that the repelling device 40 generates a repelling current and starts the repelling mode. Compared with the repelling mode in which the repelling device 40 is always turned on, the power consumption can be saved, and the biological characteristics of snails can be used for targeted snail repelling, improving the working efficiency of the repelling device 40.

[0234] In another alternative embodiment, the controller is used to electrically connect the repelling device 40 to the power supply when the charging device 200 charges the self - moving device 100.

[0235] Generally, when the self - moving device 100 is in a charging state, the self - moving device 100 is in a stationary state. At this time, it is easy for snails waiting to repel the main body to climb onto the self - moving device 100. Based on this, the controller controls the repelling device 40 to be electrically conducted with the power supply when the self - moving device 100 is in a charging state, and starts the repelling mode. Compared with the repelling mode in which the repelling device 40 is always turned on, the power consumption can be saved and the working efficiency of the repelling device 40 can be improved.

[0236] A charging device 200 provided by the present application is provided with a repelling device 40 on the outer periphery of the chassis 220 of the charging device 200, or a repelling device 40 is provided on the charging base 230 of the charging device 200. For example, a repelling device 40 is provided around the charging electrode plate of the charging base 230, or a repelling device 40 is provided around the infrared module 201 of the charging base 230. This can not only prevent snails from crawling onto the charging base 230, but also prevent snails from crawling onto the surface of the self-moving device 100 (lawn mower) parked in the parking area 220a.

[0237] Further, the current generation methods of the repelling device 40 include but are not limited to the following embodiments. The first current generation method is that the repelling device 40 includes a positive electrode and a negative electrode. When a snail crawls and contacts the positive and negative electrodes, the two are conducted to generate a repelling current. The second current generation method is that the repelling device 40 includes a conductive layer 47, and the conductive layer 47 is charged by itself. When a snail crawls onto the surface of the conductive layer 47, the snail and the conductive layer 47 form a parallel circuit, thereby generating a repelling current. The third current generation method is that the repelling device 40 includes a copper layer or a copper sheet. When a snail contacts the copper sheet, a primary battery effect can be formed through the mucus generated by the copper sheet, thereby generating a repelling current. In addition, the copper sheet will generate copper ions that are irritating to snails.

[0238] Further, the structural forms of the repelling device 40 include but are not limited to the following embodiments: The first structure is a ring-shaped strip electrode, including a first ring-shaped strip electrode (the aforementioned first electrode 41) and a second ring-shaped strip electrode (the aforementioned second electrode 42). The first ring-shaped strip electrode and the second ring-shaped strip electrode are respectively connected to the positive and negative electrodes of the power supply. The second structure is a grid-shaped electrode. The intersection points of the grid-shaped electrode are insulated, and the grid-shaped electrode can increase the contact probability between the snail and the positive and negative electrodes.

[0239] Further, the first ring-shaped strip electrode and the second ring-shaped strip electrode are arranged with a height offset to prevent users from accidentally touching the positive and negative electrodes.

[0240] Further, the repelling device 40 includes a plurality of ring-shaped strip electrodes (positive electrodes) arranged at intervals, and the voltage of each ring-shaped strip electrode is different to generate currents with different intensities between two positive electrode lines. For example, the repelling device 40 includes a first ring-shaped strip electrode, a second ring-shaped strip electrode, and a third strip electrode. The first ring-shaped strip electrode is connected to a 1V power supply, the second ring-shaped strip electrode is connected to a 3V power supply, and the third strip electrode is connected to a 7V power supply. When a snail conducts the first ring-shaped strip electrode and the second ring-shaped strip electrode, the voltage difference between the two is 2V. When the snail continues to crawl, it will conduct the second ring-shaped strip electrode and the third strip electrode, and the voltage difference between the two is 4V. That is, the voltage difference will increase, so that the current stimulation received by the snail gradually increases. Or, when the snail is larger in size and crawls onto the surface of the machine, it directly conducts the first ring-shaped strip electrode and the third strip electrode.

[0241] Further, the repelling device 40 can repel snails by means of electric shock, or can also adopt physical defense means such as a thorn net structure or spikes to repel snails.

Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present application, and these improvements and refinements are also regarded as the protection scope of the present application.
