Description

Technical Field

[0001] The present application relates to the technical field of lawn mowers, and in particular to a lawn mower detection device and a lawn mower. Background Art

[0002] Since the lawn mower detection device has the function of detecting rain, the lawn mower detection device has been widely used on lawn mowers. When the lawn mower detection device detects rain, the lawn mower will return to the base station to avoid rain under the control of the internal control component.

[0003] The lawn mower detection device generally includes a mounting part, a detection circuit and two conductive parts. The mounting part is installed on the housing of the lawn mower. The two conductive parts are located on the mounting part, and the two conductive parts are electrically connected to the control component through the detection circuit. When both conductive parts are in contact with rainwater, the detection circuit signal is turned on, and the control component controls the lawn mower to return to the base station. Chinese utility model patent CN212487313U discloses a lawn mower detection device. In the lawn mower detection device, two conductive parts are arranged on the mounting part, and there is a spacing between the two conductive parts. The mounting part is provided with a mesh-shaped channel on the peripheral side of the two conductive parts, and rainwater can flow along the mesh-shaped channel and contact the two conductive parts respectively.

[0004] Due to the existence of the mesh-shaped channel, the two conductive parts cannot be quickly connected by rainwater, resulting in a low sensitivity of the lawn mower detection device to rainwater detection. Utility Model Content

[0005] The embodiments of the present application provide a lawn mower detection device and a lawn mower, which can improve the detection sensitivity of the lawn mower detection device to detection liquids such as rainwater.

[0006] In a first aspect, an embodiment of the present application provides a lawn mower detection device, the lawn mower detection device comprising:

[0007] The mounting member has a converging surface, a first channel is arranged on the converging surface, and the first channel is used to collect the detection liquid; the detection liquid forms a continuous conductive medium in the first channel;

[0008] A detection component, comprising a first conductive member and a second conductive member, wherein the first conductive member and the second conductive member are spaced apart from each other on a busbar along a first direction, and the detection component comprises a first state and a second state, wherein in the first state, both the first conductive member and the second conductive member are in contact with a conductive medium, and in the second state, at least one of the first conductive member and the second conductive member is separated from the conductive medium;

[0009] The first channel is located in the peripheral area of ​​the detection component and between the first conductive member and the second conductive member, and the first channel extends along the first direction so that the detection liquid cannot converge in a direction other than the first direction; the first channel only includes a first outlet and a second outlet, the first outlet extends toward the surface of the first conductive member, and the second outlet extends toward the surface of the second conductive member; in the first state, the conductive medium is filled into the first outlet and the second outlet, the conductive medium contacts the first conductive member through the first outlet, and the conductive medium contacts the second conductive member through the second outlet.

[0010] In view of the low detection sensitivity of the lawn mower detection device to rainwater, the lawn mower detection device of the embodiment of the present application is provided with a first channel on the confluence surface of the mounting member. Since the first channel is located in the peripheral area of ​​the detection component and between the first conductive member and the second conductive member, the first channel extends along the first direction so that the detection liquid cannot converge in a direction other than the first direction. Therefore, when the detection liquid flows in the first channel, the flow direction of the detection liquid on the confluence surface can be guided by the first channel. At the same time, the detection liquid can only converge in the first channel along the extension direction (first direction) of the first channel to avoid the detection liquid from spreading around on the confluence surface, so that the detection liquid can quickly converge between the first conductive member and the second conductive member, and quickly form a continuous conductive medium in the first channel. In this way, the first conductive member and the second conductive member can be quickly connected through the conductive medium to improve the detection sensitivity of the lawn mower detection device to the detection liquid.

[0011] Furthermore, by setting the first outlet and the second outlet, the detection liquid collected by the conductive medium in the first channel can quickly flow to the first conductive member through the first outlet and contact the first conductive member, and can also quickly flow to the second conductive member through the second outlet and contact the second conductive member. In this way, the conductive medium can quickly contact the first conductive member and the second conductive member at the same time, so that the first conductive member and the second conductive member are quickly connected, which can further improve the detection sensitivity of the lawn mower detection device to the detection liquid.

[0012] In some optional embodiments, the first channel includes a liquid collection channel and a communication channel.

[0013] The communication channel is located on one side of the detection component in the second direction, the communication channel is located between the first conductive member and the second conductive member, and the communication channel extends along the first direction so that the detection liquid cannot flow in a direction other than the first direction; the second direction is perpendicular to the first direction;

[0014] The liquid collection channel is located on the side of the connecting channel away from the detection component, and the liquid collection channel has a first outlet and a second outlet; the two ends of the connecting channel are respectively connected to the first outlet and the second outlet, and at least part of the first conductive member and at least part of the second conductive member are both located in the connecting channel.

[0015] By limiting the position of the connecting channel and the liquid collecting channel relative to the detection component, the first channel is located in the peripheral area of ​​the detection component, and at the same time, the first channel is located between the first conductive member and the second conductive member. Since the two ends of the connecting channel are respectively connected to the first outlet and the second outlet, so that the connection between the first liquid collecting section and the second outlet is realized through the connecting channel, the detection liquid in the first liquid collecting section can be converged into the connecting channel. Moreover, through the connecting channel, the detection liquid can only be converged in the connecting channel along the extension direction (first direction) of the connecting channel, so that the detection liquid can quickly form a continuous conductive medium in the connecting channel, so as to conduct the first conductive member and the second conductive member through the conductive medium, thereby realizing the detection function of the lawn mower detection device for the detection liquid.

[0016] In some optional embodiments, the liquid collection channel includes a first liquid collection section, and the first liquid collection section is arranged around one side of the detection component in the second direction;

[0017] Along the first direction, the middle part of the first liquid collecting section is located between the first conductive member and the second conductive member, and the middle part of the first liquid collecting section extends along the first direction, so that the detection liquid cannot converge in a direction other than the first direction, so that the detection liquid can only converge in the first direction in the middle part of the first liquid collecting section;

[0018] Along the second direction, the first end of the first liquid collecting section extends toward one side of the first conductive member, so that the detection liquid cannot converge in a direction other than the second direction; the first end of the first liquid collecting section has a first outlet, and the first outlet faces a side of the first conductive member away from the second conductive member. In this way, the detection liquid can only converge along the second direction at the first end of the first liquid collecting section and fill the first outlet.

[0019] Along the second direction, the second end of the first liquid collecting section extends toward one side of the second conductive member, so that the detection liquid cannot converge in a direction other than the second direction; the second end of the first liquid collecting section has a second outlet, and the second outlet faces the side of the second conductive member away from the first conductive member. In this way, the detection liquid can only converge along the second direction at the second end of the first liquid collecting section and fill the second outlet. Through the arrangement of the first liquid collecting section, the detection liquid can be quickly gathered into the connecting channel in the first liquid collecting section.

[0020] One end of the communication channel is located between the first outlet and the first conductive member to communicate with the first outlet, and the other end of the communication channel is located between the second outlet and the second conductive member to communicate with the second outlet.

[0021] The first outlet and the second outlet can be connected through the two ends of the connecting channel, so that the detection liquid in the first liquid collecting section converges into the connecting channel, and after merging with the detection liquid in the connecting channel, a conductive medium that contacts the first conductive member and the second conductive member at the same time can be quickly formed in the connecting channel.

[0022] In addition, after the first liquid collecting section is connected to the connecting channel, a closed first channel is formed. By setting the closed first channel, it is possible to prevent the detection liquid from overflowing from around the first liquid collecting section when the lawn mower is in motion.

[0023] In some optional embodiments, the first liquid collecting section is shaped like a racetrack, an ellipse or a rectangle, so that when the first liquid collecting section is wound around one side of the detection component in the second direction, a first outlet and a second outlet can be formed at two ends of the first liquid collecting section respectively.

[0024] In some optional embodiments, the number of the first liquid collecting sections is N, and N is greater than or equal to 2;

[0025] The N first liquid collecting sections are sequentially arranged on the confluence surface along the first direction, and along the second direction, the N first liquid collecting sections are sequentially arranged around the same side of the detection component, so that the first outlets of the N first liquid collecting sections are sequentially arranged along the Y direction on one side of the detection component in the X direction, and the second outlets of the N first liquid collecting sections are sequentially arranged along the Y direction on the other side of the detection component in the X direction.

[0026] Furthermore, by setting up N first liquid collecting sections, more detection liquids located in the peripheral area of ​​the detection component can be converged to the connecting channel, thereby increasing the convergence amount of the detection liquid in the connecting channel, and shortening the time for forming a conductive medium that is in contact with the first conductive part and the second conductive part at the same time in the connecting channel, so as to further speed up the conduction time of the first conductive part and the second conductive part, and improve the detection sensitivity of the lawn mower detection device to the detection liquid.

[0027] In some optional embodiments, along the second direction, the N first liquid collecting sections are arranged gradually from the edge of the detection component to the middle of the detection component.

[0028] Compared with the case where the first liquid collecting section is located in the middle of the detection component, when the first liquid collecting section is located at the edge of the detection component, the detection liquid converges into the connecting channel through the first outlet and the second outlet, which can shorten the time for forming a conductive medium that is in contact with the first conductive part and the second conductive part at the same time in the connecting channel, thereby improving the detection sensitivity of the lawn mower detection device to the detection liquid.

[0029] In some optional embodiments, the first liquid collecting section is a first groove provided on the confluence surface, and the mounting member has a first separator between adjacent first grooves;

[0030] The first spacer has a first end and a second end along the thickness direction of the mounting member, the cross-sectional area of ​​the first end is smaller than that of the second end, and the first end faces the notch of the first groove so that the first spacer can form a tip at the first end.

[0031] Due to the presence of the pointed end, the water film of the detection liquid can be punctured so that the detection liquid can quickly disperse and converge in the first groove, thereby further shortening the time for forming a conductive medium that is in contact with the first conductive part and the second conductive part at the same time in the connecting channel, thereby improving the detection sensitivity of the lawn mower detection device to the detection liquid.

[0032] In some optional embodiments, the liquid collection channel includes a first liquid collection section and a second liquid collection section, the first liquid collection section is located on a side of the first conductive member away from the second conductive member, and the second liquid collection section is located on a side of the second conductive member away from the first conductive member;

[0033] The first liquid collecting section has a first outlet, the second liquid collecting section has a second outlet, one end of the communication channel is located between the first outlet and the first conductive member to connect the first outlet, and the other end of the communication channel is located between the second outlet and the second conductive member to connect the second outlet. In this way, the first outlet and the second outlet can be connected through the two ends of the communication channel.

[0034] Moreover, through the arrangement of the first liquid collecting section and the second liquid collecting section, the detection liquid can also be collected in the first liquid collecting section and the second liquid collecting section to avoid the detection liquid from spreading everywhere on the converging surface, so that the detection liquid can be quickly collected into the connecting channel along the first liquid collecting section and the second liquid collecting section, and converge in the connecting channel to form a conductive medium that is in contact with the first conductive part and the second conductive part at the same time, thereby realizing the detection function of the lawn mower detection device for the detection liquid.

[0035] In some optional embodiments, the first liquid collecting section and the second liquid collecting section are arranged on the same side of the detection assembly in the second direction, and along the third direction, one end of the first liquid collecting section having the first outlet extends toward the first conductive member, so that the detection liquid cannot flow to a direction other than the third direction; the third direction intersects the first direction and the second direction;

[0036] Along the fourth direction, one end of the second liquid collecting section having the second outlet extends toward the second conductive member so that the detection liquid cannot flow in a direction other than the fourth direction; the fourth direction intersects the first direction and the second direction, and the fourth direction is different from the third direction.

[0037] This ensures that the detection liquid can only flow along the extension direction of the first and second liquid collecting sections during the process of converging in the first and second liquid collecting sections, so that the detection liquid can be quickly gathered in the connecting channel.

[0038] Furthermore, the first outlet faces the end of the first conductive member, and the second outlet faces the end of the second conductive member; the end of the second conductive member and the end of the first conductive member are respectively located in the two ends of the connecting channel, so that the detection liquid in the first liquid collecting section and the second liquid collecting section converge into the connecting channel, and when a conductive medium that contacts the end of the first conductive member and the end of the second conductive member at the same time is formed in the connecting channel, the detection liquid can realize the conduction function of the first conductive member and the second conductive member, thereby realizing the detection function of the lawn mower detection device on the detection liquid.

[0039] In some optional embodiments, the second liquid collection section is symmetrically arranged relative to the first liquid collection section so that the second liquid collection section and the first liquid collection section have basically equal water flow paths, thereby ensuring that the time for the detection liquid in the second liquid collection section and the first liquid collection section to converge into the connecting channel is basically equal, thereby ensuring that the detection can be quickly converged from the second liquid collection section and the first liquid collection section into the connecting channel at the same time.

[0040] In some optional embodiments, the first liquid collecting section and the second liquid collecting section are both recessed structures arranged on the confluence surface. In this way, while realizing the flow collecting function of the first liquid collecting section and the second liquid collecting section on the detection liquid, there is no need to make grooves on the confluence surface, which can simplify the structure of the mounting part.

[0041] In some optional embodiments, the first liquid collecting section and the second liquid collecting section are arranged on both sides of the detection component in the first direction, and along the first direction, one end of the first liquid collecting section having the first outlet extends toward the first conductive member, so that the detection liquid cannot flow in a direction other than the first direction; along the first direction, one end of the second liquid collecting section having the second outlet extends toward the second conductive member, so that the detection liquid cannot flow in a direction other than the first direction;

[0042] The first outlet faces the middle of the first conductive member, and the second outlet faces the middle of the second conductive member.

[0043] In this way, it can be ensured that the detection liquid can only converge along the extension direction of the first and second liquid collecting sections during the convergence of the first and second liquid collecting sections, so that the detection liquid can quickly converge into the connecting channel. When one end of the connecting channel is located between the first outlet and the first conductive member to connect the first outlet, and one end of the connecting channel is located between the second outlet and the second conductive member to connect the second outlet, the first outlet and the second outlet can also be connected through the connecting channel to achieve the convergence of the detection liquid in the connecting channel, and form a conductive medium that is in contact with the first conductive member and the second conductive member at the same time.

[0044] In some optional embodiments, the first liquid collecting section and the second liquid collecting section are both grooves arranged on the converging surface, so as to realize the flow collecting function of the first liquid collecting section and the second liquid collecting section on the detection liquid.

[0045] In some optional embodiments, the number of the first liquid collecting sections and the number of the second liquid collecting sections are both multiple, and the multiple first liquid collecting sections and the multiple second liquid collecting sections are sequentially arranged on the confluence surface along the second direction, so that the first outlets of the multiple first liquid collecting sections are sequentially arranged along the second direction on one side of the detection component in the first direction, and the second outlets of the multiple first liquid collecting sections are sequentially arranged along the second direction on the other side of the detection component in the first direction.

[0046] Moreover, by setting up multiple first liquid collecting sections and multiple second liquid collecting sections, more detection liquid in the peripheral area of ​​the detection component can also be converged into the connecting channel, shortening the time for forming a conductive medium that is in contact with the first conductive part and the second conductive part at the same time in the connecting channel, so as to further shorten the conduction time of the first conductive part and the second conductive part, and improve the detection sensitivity of the lawn mower detection device to the detection liquid.

[0047] In some optional embodiments, the converging surface further includes a flow guiding channel, the flow guiding channel is located in the peripheral area of ​​the detection component, and the first outlet and the second outlet are both connected to the flow guiding channel.

[0048] By setting up the guide channel, the detection liquid can be quickly converged into the connecting channel through the first outlet or the second outlet, and the convergence amount of the detection liquid in the connecting channel can also be increased, shortening the time for forming a conductive medium that contacts the first conductive member and the second conductive member at the same time in the connecting channel, so as to further shorten the conduction time of the first conductive member and the second conductive member, and improve the detection sensitivity of the lawn mower detection device to the detection liquid.

[0049] In some optional embodiments, the guide channel has an inlet end and an outlet end, and the outlet end is connected to the first outlet or the second outlet to achieve communication between the first outlet or the second outlet and the guide channel;

[0050] Along the projection direction of the converging surface on the mounting piece, the height of the guide channel at the inlet end is higher than the height of the outlet end, so that the detection liquid can flow in the guide channel toward the outlet end under the action of gravity, thereby quickly converging into the connecting channel through the first outlet or the second outlet; wherein the projection direction of the converging surface on the mounting piece is perpendicular to the first direction and the second direction.

[0051] In some optional embodiments, along the projection direction of the converging surface on the mounting member, the height of the first liquid collecting section at the first outlet is lower than the height of the first liquid collecting section at other positions, and the height of the second liquid collecting section at the second outlet is lower than the height of the second liquid collecting section at other positions;

[0052] The projection direction of the converging surface on the mounting component is perpendicular to the first direction and the second direction.

[0053] In this way, the detection liquid can flow in the first liquid collecting section toward the first outlet under the action of gravity. At the same time, the detection liquid can flow in the second liquid collecting section toward the second outlet under the action of gravity, so that the detection liquid can quickly converge from the first liquid collecting section and the second liquid collecting section into the connecting channel respectively.

[0054] In some optional embodiments, the first channel includes a liquid collection channel, the liquid collection channel includes a first liquid collection section, the first liquid collection section is arranged around one side of the detection component in the second direction, and the middle of the first liquid collection section is located between the first conductive member and the second conductive member, and the middle of the first liquid collection section extends along the first direction, so that the detection liquid cannot converge in a direction other than the first direction, so that the detection liquid can only converge in the first direction in the middle of the first liquid collection section. At the same time, the first channel can be located in the peripheral area of ​​the detection component, and the first channel can be located between the first conductive member and the second conductive member.

[0055] Along the second direction, the first end of the first liquid collecting section extends toward one side of the first conductive member, so that the detection liquid cannot flow in a direction other than the second direction; the first end of the first liquid collecting section has a first outlet, and the first outlet extends to the surface of the first conductive member;

[0056] Along the second direction, the second end of the first liquid collecting section extends toward one side of the second conductive member, so that the detection liquid cannot flow in a direction other than the second direction; the second end of the first liquid collecting section has a second outlet, and the second outlet extends to the surface of the second conductive member.

[0057] In this way, the detection liquid can only converge along the second direction at the first end of the first liquid collecting section and fill the first outlet, and the detection liquid can only converge along the second direction at the second end of the first liquid collecting section and fill the second outlet, so that the detection liquid can quickly converge in the first liquid collecting section and form a conductive medium. At the same time, when the conductive medium is filled to the first outlet and the second outlet, it can contact the surface of the first conductive member and the second conductive member at the same time, so as to conduct the first conductive member and the second conductive member through the conductive medium, and can also improve the detection sensitivity of the lawn mower detection device to the detection liquid.

[0058] In some optional embodiments, at least one of the first conductive member and the second conductive member is a long strip structure, and the length direction and thickness direction of the long strip structure are both perpendicular to the first direction.

[0059] When the number of the first liquid collecting sections is N, by setting up the long strip structure, it can be ensured that the first outlet and the second outlet of the N first liquid collecting sections both face the first conductive part or the second conductive part. At the same time, it can also increase the contact area between the first conductive part and the second conductive part and the detection liquid, thereby enhancing the conduction effect between the first conductive part and the second conductive part, so as to further improve the detection sensitivity of the lawn mower detection device to the detection liquid.

[0060] In some optional embodiments, the number of the first channels is two, and the two first channels are arranged on both sides of the mounting member in the second direction, so as to ensure that the two first channels are arranged in the peripheral area of ​​the detection component, while the detection liquid in the peripheral area of ​​the detection component can be collected through the two first channels, so as to further improve the conduction rate of the first conductive member and the second conductive member, and improve the detection sensitivity of the lawn mower detection device to the detection liquid; wherein the second direction is perpendicular to the first direction.

[0061] In some optional embodiments, the busbar surface includes a horizontal surface and two first flow guiding surfaces, and the first conductive member and the second conductive member are arranged on the horizontal surface at intervals along the first direction;

[0062] Along the first direction, two first guide surfaces are obliquely arranged on both sides of the horizontal plane, and the first guide surfaces are used to guide the detection liquid to the horizontal plane; part of the first channel is arranged on the two first guide surfaces, and the two first channels are symmetrically arranged on both sides of the mounting part in the second direction.

[0063] In this way, while the two first channels are arranged on the confluence surface, the detection liquid located in the peripheral area of ​​the detection component can be guided to one side of the horizontal plane through the two first guide surfaces, so that more detection liquid can flow into the connecting channel, thereby further increasing the confluence amount of the detection liquid in the connecting channel, improving the conduction rate of the first conductive member and the second conductive member, and improving the detection sensitivity of the lawn mower detection device to the detection liquid.

[0064] In some optional embodiments, the converging surface further includes a second guide surface, the second guide surface is connected between the first guide surface and the horizontal plane, the second guide surface is inclined relative to the horizontal plane, and the second guide surface is used to guide the detection liquid to the horizontal plane;

[0065] The first channel is arranged on a side of the first flow guiding surface adjacent to the second flow guiding surface.

[0066] The two first flow guide surfaces, the two second flow guide surfaces and the horizontal plane can form a concave converging surface, the first flow guide surface and the second flow guide surface are arranged around the horizontal plane, and form a slope surface of the concave converging surface, and the area where the horizontal plane is located is the lowest area of ​​the concave converging surface. Due to the existence of the slope surface, the detection liquid located in the peripheral area of ​​the detection component can be quickly guided to one side of the horizontal plane through the first flow guide surface and the second flow guide surface, so that more detection liquid can be converged to the connecting channel, so as to further increase the convergence amount of the detection liquid in the connecting channel, improve the conduction rate of the first conductive member and the second conductive member, and improve the detection sensitivity of the lawn mower detection device to the detection liquid.

[0067] In some optional embodiments, a second channel is provided on the confluence surface, the second channel is used to collect the detection liquid, the second channel is located in the area surrounded by the first conductive member and the second conductive member, and along the first direction, the two ports of the second channel extend to the surface of the first conductive member and the surface of the second conductive member respectively, so that the detection liquid cannot converge in a direction other than the first direction.

[0068] On the basis of the first channel, the detection liquid between the first conductive member and the second conductive member can be collected through the second channel, and the detection liquid can quickly form another continuous conductive medium in the second channel. When the conductive medium is filled in the two ends of the second channel and contacts the surfaces of the first conductive member and the second conductive member at the same time, the detection liquid on the confluence surface can contact the surface of the first conductive member and the second conductive member at the same time from different directions, which can further improve the detection sensitivity of the lawn mower detection device to the detection liquid, and at the same time, it can also enhance the conduction effect of the first conductive member and the second conductive member, and enhance the detection stability of the lawn mower detection device to the detection liquid.

[0069] In some optional embodiments, there are multiple second channels, and the multiple second channels are spaced apart on the confluence surface along the second direction, and the second direction is perpendicular to the first direction.

[0070] In this way, the two ends of the multiple second channels can be arranged in sequence between the first conductive member and the second conductive member along the second direction. At the same time, the multiple second channels can be distributed between the first conductive member and the second conductive member in a relatively uniform manner, so as to improve the collection capacity of the multiple second channels for the detection liquid, so that multiple conductive media that are in contact with the first conductive member and the second conductive member at the same time can be formed between the first conductive member and the second conductive member, so as to further improve the detection sensitivity of the lawn mower detection device to the detection liquid and enhance the detection stability of the lawn mower detection device to the detection liquid.

[0071] In some optional embodiments, the second channel is a second groove arranged on the confluence surface, and the mounting member has a second partition between adjacent second grooves. Along the thickness direction of the mounting member, the second partition has a third end and a fourth end, the cross-sectional area of ​​the third end is smaller than the cross-sectional area of ​​the fourth end, and the third end faces the notch of the second groove, so that the second partition can form a tip at the first end as well.

[0072] Due to the presence of the pointed end, the water film of the detection liquid can be pierced so that the detection liquid can quickly disperse and converge in the second groove, thereby further shortening the time for forming a conductive medium that is in contact with the first conductive member and the second conductive member at the same time in the second channel, thereby improving the detection sensitivity of the lawn mower detection device to the detection liquid.

[0073] In some optional embodiments, the mounting member is provided with a water collecting groove on the confluence surface, the water collecting groove is connected to the channel, and a portion of at least one of the first conductive member and the second conductive member is located in the water collecting groove so that the detection liquid collected in the water collecting groove can be converged into the first channel, so that the first conductive member and the second conductive member are quickly connected. In addition, since a portion of at least one of the first conductive member and the second conductive member is located in the water collecting groove, the conduction area of ​​the first conductive member and the second conductive member can be increased, so as to further enhance the detection stability of the detection device of the lawn mower for the detection liquid.

[0074] In some optional embodiments, the detection component also includes a detection circuit, the detection circuit includes a first connection end and a second connection end, the first connection end is connected to the first conductive member, the second connection end is connected to the second conductive member, and in the first state, the detection circuit signal is turned on.

[0075] By setting the first connection end and the second connection end, the connection between the detection circuit and the first conductive member and the second conductive member can be realized, so that the first conductive member and the second conductive member are both in contact with the conductive medium, so that the detection circuit signal of the detection component is turned on in the first state, and the detection function of the lawn mower detection device for detecting the detection liquid can be realized. In the second aspect, an embodiment of the present application provides a lawn mower, the lawn mower includes a shell, a control component and a lawn mower detection device as described above, the shell includes a mounting groove, the mounting groove includes an opening, the lawn mower detection device is arranged in the mounting groove through the opening, and the confluence surface is exposed on the shell, and the control component is electrically connected to the detection component.

[0076] The lawn mower detection device is arranged in the installation groove through an opening, and the confluence surface is exposed on the shell, so that when the lawn mower detection device is installed on the shell, rainwater or other detection liquid can fall on the confluence surface, thereby realizing the detection function of the lawn mower detection device on the detection liquid. On this basis, since the control component is electrically connected to the detection component, when the lawn mower detection device detects rainwater or other detection liquid on the confluence surface, the control component system can control the lawn mower to stop mowing and return to the base station to avoid rain.

[0077] In some optional embodiments, when the lawn mower detection device is arranged in the installation groove, there is a distance between the lawn mower detection device and the opening to prevent the detection liquid on the confluence surface from overflowing to the outside of the installation groove through the opening when the lawn mower is moving, thereby affecting the detection sensitivity of the lawn mower detection device to the detection liquid.

[0116] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0117] Lawn mower is also called weeder, lawn mower, lawn trimmer, etc. A lawn mower is a mechanical tool used to trim lawns, vegetation, etc. It can save the working time of weeding workers and has been widely used in trimming lawns, vegetation, etc.

[0118] As described in the background art, the lawn mower detection device has been widely used in lawn mowers. When the lawn mower detection device detects rain, the lawn mower stops mowing and returns to the base station to avoid rain under the control of the internal control component.

[0119] Figure 1 The schematic diagram of the structure of an existing lawn mower detection device 100a is shown schematically. This lawn mower detection device 100a is described in Chinese utility model patent CN212487313U. Figure 1 As shown, the lawn mower detection device 100a generally includes a mounting member 1a and two conductive members 2. The two conductive members 2 include a first conductive member 21a and a second conductive member 22a. The two conductive members 2 are arranged on the mounting member 1a. The mounting member 1a is provided with a mesh-shaped channel 3 on the circumferential side of the two conductive members 2. The mesh-shaped channel 3 can be understood as a mesh-shaped channel on the mounting member 1a. A portion of the mesh-shaped channel 3 is located between the two conductive members 2, and another portion of the mesh-shaped channel 3 is surrounded on a side of the two conductive members 2 away from each other. When rainwater can flow along the mesh-shaped channel 3 and form a continuous conductive medium water flow that is in contact with the two conductive members 2 at the same time, the conduction of the two conductive members 2 can be achieved.

[0120] Due to the existence of the mesh channel 3, rainwater will be dispersed along the mesh channel 3 and cannot quickly converge between the two conductive parts 2 along the mesh channel, which is not conducive to forming a continuous conductive medium, so that the two conductive parts 2 cannot be quickly connected through the conductive medium, thereby causing the lawn mower detection device 100a to have a low sensitivity to rainwater detection.

[0121] Compared with rainwater located between the two conductive members 2, when rainwater is located in the peripheral area of ​​the detection component and flows in the mesh channel, it will be dispersed more seriously, which is more unfavorable for forming a continuous conductive medium, thus causing the lawn mower detection device 100a to have lower sensitivity to rainwater detection.

[0122] It should be noted that the peripheral area of ​​the detection component can be understood as the outer area of ​​the unit when the first conductive member 21a and the second conductive member 22a are regarded as a unit. The outer area does not include the area of ​​the unit between the first conductive member 21a and the second conductive member 22a.

[0123] In view of this, an embodiment of the present application provides a lawn mower detection device, which is provided with a first channel on the mounting member. The detection liquid in the peripheral area of ​​the detection component can be collected through the first channel, and the detection liquid can be quickly converged between the first conductive member and the second conductive member, so that the detection liquid can form a continuous conductive medium. When the conductive medium contacts the first conductive member and the second conductive member at the same time, the first conductive member and the second conductive member can be quickly conductive, thereby improving the detection sensitivity of the lawn mower detection device to the detection liquid.

[0124] The detection liquid may include liquids that can be conductive, such as rainwater. When the detection liquid is rainwater, the lawn mower detection device of the embodiment of the present application can improve the detection sensitivity to rainwater.

[0125] The following text takes rainwater as an example of the detected liquid and further describes the structure of the lawn mower detection device in conjunction with the corresponding drawings.

[0126] Figure 2 The schematic diagram shows the structure of the first lawn mower detection device at a first viewing angle. Figure 2 As shown, the lawn mower detection device 100 includes a mounting member 1. The mounting member 1 has a converging surface 10. A first channel 11 is provided on the converging surface 10. The first channel 11 is used to collect the detection liquid. The detection liquid forms a continuous conductive medium in the first channel 11, so that the lawn mower detection device 100 can detect the detection liquid through the conductive medium in the first channel 11.

[0127] See also Figure 2 As shown, the lawn mower detection device 100 also includes a detection component. The detection component includes a first conductive member 21 and a second conductive member 22. The first conductive member 21 and the second conductive member 22 can both be electrodes or other conductive structures. When the first conductive member 21 and the second conductive member 22 are both electrodes, one of the first conductive member 21a and the second conductive member 22a can be a positive electrode, and the other can be a negative electrode.

[0128] The first conductive member 21 and the second conductive member 22 are arranged on the busbar 10 at intervals along the first direction. The first direction is the X direction. The X direction is used to replace the first direction below. The detection component includes a first state and a second state. In the first state, the first conductive member 21 and the second conductive member 22 are both in contact with a continuous conductive medium, so that the first conductive member 21 and the second conductive member 22 are connected through the conductive medium. In the second state, at least one of the first conductive member 21 and the second conductive member 22 is separated from the conductive medium, and the first conductive member 21 cannot be connected to the second conductive member 22.

[0129] See also Figure 2 As shown, the first channel 11 is located in the peripheral area of ​​the detection component and between the first conductive member 21 and the second conductive member 22, and the first channel 11 extends along the X direction, so that the detection liquid cannot converge in a non-X direction. For example, when the first channel 11 extends along the X direction, the detection liquid can not converge in the Y direction. Among them, the second direction is perpendicular to the X direction. The second direction is the Y direction. The second direction is replaced by the Y direction below. The X direction is parallel to the extension direction of the first channel 11 between the first conductive member 21 and the second conductive member 22, that is, the first channel extends along the X direction between the first conductive member 21 and the second conductive member 22. The detection component has a non-projection area in the middle area of ​​the converging surface 10. The converging surface 10 forms the above-mentioned non-projection area in the area between the first conductive member 21 and the second conductive member 22. The first channel 11 is located between the first conductive member 21 and the second conductive member 22. It can be understood that along the X direction, the converging surface 10 is provided with the first channel 11 corresponding to the above-mentioned non-projection area.

[0130] Compared with the mesh channel 3 mentioned above, since the first channel 11 is located in the peripheral area of ​​the detection component and between the first conductive member 21 and the second conductive member 22, and the first channel 11 extends along the X direction, when the detection liquid flows in the first channel 11, the flow direction of the detection liquid on the confluence surface 10 can be guided by the first channel 11, and at the same time, the detection liquid can only converge along the extension direction (X direction) of the first channel 11 in the first channel 11 to avoid the detection liquid from spreading all over the confluence surface 10, so that the detection liquid can quickly converge between the first conductive member 21 and the second conductive member 22, and quickly form a conductive medium in the first channel 11. In this way, the first conductive member 21 and the second conductive member 22 can be quickly connected through the conductive medium to improve the detection sensitivity of the lawn mower detection device 100 to the detection liquid.

[0131] The first channel 11 includes only a first outlet 1111 and a second outlet 1121. The first outlet 1111 extends toward the surface of the first conductive member 21. The second outlet 1121 extends toward the surface of the second conductive member 22. The first outlet 1111 and the second outlet 1121 are filled with a conductive medium.

[0132] In the first state, the conductive medium contacts the first conductive member 21 through the first outlet 1111, and contacts the second conductive member 22 through the second outlet 1121, so that the conductive medium can quickly converge to the first conductive member 21 through the first outlet 1111 in the first channel 11 and contact the first conductive member 21, and at the same time, it can also quickly converge to the second conductive member 22 through the second outlet 1121 and contact the second conductive member 22. In this way, the conductive medium can quickly contact the first conductive member 21 and the second conductive member 22 at the same time, so that the first conductive member 21 and the second conductive member 22 are quickly connected. In this way, the first conductive member 21 and the second conductive member 22 after being connected can be used for detecting liquid on the converging surface 10, and the detection sensitivity of the lawn mower detection device 100 to the detection liquid can be further improved.

[0133] The following is a further description of the detection function of the lawn mower detection device 100 for detecting liquid in conjunction with the accompanying drawings.

[0134] Figure 3 The schematic diagram shows the structure of the detection component and the control component. Figure 3 As shown, the detection component may further include a detection circuit. The detection circuit includes a first connection end and a second connection end. The first connection end is connected to the first conductive member 21. The second connection end is connected to the second conductive member 22. By setting the first connection end and the second connection end, the connection between the detection circuit and the first conductive member 21 and the second conductive member 22 can be realized, so that the first conductive member 21 and the second conductive member 22 are both in contact with the conductive medium, so that when the detection component is in the first state, the detection circuit signal is turned on, and the lawn mower detection device 100 can realize the detection function of the detection liquid.

[0135] It should be noted that the structure of the detection circuit can be determined according to the structure of the lawn mower in the related art, and will not be further described in this application.

[0136] See also Figure 3 As shown, the lawn mower has a control component, which is electrically connected to the detection component. Specifically, the control component can be electrically connected to the detection circuit, so that when the signal of the detection circuit is turned on, the control component controls the lawn mower to stop mowing and return to the base station to avoid rain.

[0137] It should be noted that a lawn mower generally includes a walking mechanism, a driving assembly and a cutting assembly. The control assembly is connected to the walking mechanism and can control the movement of the walking mechanism to drive the lawn mower to walk. The cutting assembly is arranged on the driving assembly, and the control assembly is connected to the driving assembly to control the rotation of the driving assembly, thereby driving the cutting assembly to rotate, so that the lawn is cut when the cutting assembly rotates.

[0138] Since the control component is electrically connected to the detection component, when the signal of the detection circuit is turned on, the control component can control the start and stop state of the drive component, thereby adjusting the lawn mower to stop mowing and control the movement of the walking mechanism to drive the lawn mower to walk and return to the base station to avoid rain. The structure of the control component, the walking mechanism, the drive component and the cutting component can be determined according to the structure of the lawn mower in the related art, and will not be further described in this application.

[0139] See also Figure 2 As shown, in some embodiments, the first channel 11 may include a liquid collection channel and a connecting channel 113. The connecting channel 113 is located on one side of the detection component in the Y direction. The connecting channel 113 is located between the first conductive member 21 and the second conductive member 22, and the connecting channel 113 extends along the X direction so that the detection liquid cannot flow in a non-X direction. For example, the connecting channel 113 can prevent the detection liquid from converging in the Y direction. In this way, the detection liquid can only converge along the extension direction (X direction) of the connecting channel 113 in the connecting channel 113, so that the detection liquid can quickly form a continuous conductive medium in the connecting channel 113. In addition, the first channel 11 can be located between the first conductive member 21 and the second conductive member 22. The liquid collection channel is located on the side of the connecting channel 113 away from the detection component, and because the connecting channel 113 is located on one side of the detection component in the Y direction, the first channel 11 can be located in the peripheral area of ​​the detection component.

[0140] See also Figure 2 As shown, the liquid collecting channel has a first outlet 1111 and a second outlet 1121. The two ends of the communication channel 113 are respectively connected to the first outlet 1111 and the second outlet 1121, so that the communication between the first outlet 1111 and the second outlet 1121 of the liquid collecting channel is realized through the communication channel 113, so that the detection liquid in the liquid collecting channel can be converged into the communication channel 113. At least part of the first conductive member 21 and at least part of the second conductive member 22 are both located in the communication channel 113, so that the detection liquid in the liquid collecting channel is converged into the communication channel 113, and when a conductive medium that contacts the first conductive member 21 and the second conductive member 22 at the same time is formed in the communication channel 113, the conductive medium can conduct the first conductive member 21 and the second conductive member 22, thereby realizing the detection function of the lawn mower detection device 100 for the detection liquid.

[0141] Since the two ends of the connecting channel 113 are connected to the first outlet 1111 and the second outlet 1121 respectively, and at least part of the first conductive member 21 and at least part of the second conductive member 22 are both located in the connecting channel 113, part of the detection liquid in the liquid collecting channel will converge to the first outlet 1111, and converge along the connecting channel 113 in the direction of the second outlet 1121, and the detection liquid first contacts the first conductive member 21 during the converging process. At the same time, part of the detection liquid in the liquid collecting channel will converge to the second outlet 1121, and converge along the connecting channel 113 in the direction of the first outlet 1111, and contact the second conductive member 22 during the converging process. When these two parts of the detection liquid converge in the connecting channel 113, a continuous conductive medium will be formed in the first channel 11, and at the same time, the conductive medium will be filled to the first outlet 1111 and the second outlet 1121, and contact the first conductive member 21 and the second conductive member 22 at the same time.

[0142] Alternatively, the detection liquid in the liquid collection channel can also converge to one of the first outlet 1111 and the second outlet 1121, and converge along the connecting channel 113 in the direction of the other of the first outlet 1111 and the second outlet 1121, and contact the first conductive member 21 and the second conductive member 22 during the convergence process, and can also form a conductive medium in the first channel 11 that is in contact with the first conductive member 21 and the second conductive member 22 at the same time.

[0143] Compared with the detection liquid converging to the first outlet 1111 or the second outlet 1121, when the detection liquid converging to the first outlet 1111 and the second outlet 1121 at the same time, the detection liquid can be more quickly converged in the connecting channel 113 to form a conductive medium that contacts the first conductive member 21 and the second conductive member 22 at the same time, which can further improve the detection sensitivity of the lawn mower detection device 100 to the detection liquid. This will be further explained in conjunction with the specific structure below, and will not be further elaborated here.

[0144] Figure 4 The schematic diagram of the structure of the second lawn mower detection device is shown schematically. Figure 2 ) is different in that the first channel 11 of the second lawn mower detection device only includes a liquid collection channel, and no connecting channel 113 is provided.

[0145] See also Figure 4As shown, the liquid collecting channel in the second lawn mower detection device only includes the first liquid collecting section 111, that is, the first liquid collecting section 111 constitutes the liquid collecting channel. Therefore, the first liquid collecting section 111 has a first outlet 1111 and a second outlet 1121. The first liquid collecting section 111 is arranged around one side of the detection component in the Y direction. The middle part of the first liquid collecting section 111 is located between the first conductive member 21 and the second conductive member 22, and the middle part of the first liquid collecting section 111 extends along the X direction so that the detection liquid cannot converge in a non-X direction. For example, the middle part of the first liquid collecting section 111 can prevent the detection liquid from converging in the Y direction. In this way, the detection liquid can only converge in the X direction in the first liquid collecting section 111, so that the detection liquid can quickly converge in the first liquid collecting section 111 and form a continuous conductive medium in the first liquid collecting section 111. Furthermore, by disposing the first liquid collecting section 111 , the first channel 11 is located in the peripheral area of ​​the detection component, and can also be located between the first conductive member 21 and the second conductive member 22 .

[0146] See also Figure 3 As shown, along the Y direction, the first end of the first liquid collecting section 111 extends toward one side of the first conductive member 21, so that the detection liquid cannot converge in a direction other than the Y direction. For example, the first end of the first liquid collecting section 111 can prevent the detection liquid from converging in the X direction. The first end of the first liquid collecting section 111 has a first outlet 1111. The first outlet 1111 extends to the surface of the first conductive member 21. In this way, the detection liquid can only converge along the Y direction at the first end of the first liquid collecting section 111 and fill the first outlet 1111.

[0147] Along the Y direction, the second end of the first liquid collecting section 111 extends toward one side of the second conductive member 22, so that the detection liquid cannot converge in a direction other than the Y direction. For example, the second end of the first liquid collecting section 111 can also prevent the detection liquid from converging in the X direction. The second end of the first liquid collecting section 111 has a second outlet 1121. The second outlet 1121 extends to the surface of the second conductive member 22. In this way, the detection liquid can only converge along the Y direction at the second end of the first liquid collecting section 111 and fill the second outlet 1121.

[0148] On the basis that the detection liquid cannot converge in a direction other than the X direction in the middle of the first liquid collecting section 111, the first end and the second end of the first liquid collecting section 111 jointly prevent the detection liquid from converging in a direction other than the Y direction, so that the detection liquid cannot spread around in the first liquid collecting section 111, and can be better quickly gathered in the first liquid collecting section 111, and a continuous conductive medium can be quickly formed in the first liquid collecting section 111.

[0149] Compared with the case where there is no first channel 11 on the busbar 10, when the conductive medium in the first liquid collecting section 111 is filled to the first outlet 1111 and the second outlet 1121, it can directly contact the surface of the first conductive member 21 through the first outlet 1111, and directly contact the surface of the second conductive member 22 through the second outlet 1121, so as to conduct the first conductive member 21 and the second conductive member 22 through the conductive medium, which can also improve the detection sensitivity of the lawn mower detection device 100 to the detection liquid.

[0150] The first liquid collecting section 111 is in a racetrack, elliptical or rectangular shape, so that when the first liquid collecting section 111 is wound around one side of the detection assembly in the Y direction, a first outlet 1111 and a second outlet 1121 can be formed at two ends of the first liquid collecting section 111 respectively.

[0151] Figure 5 The schematic diagram of the structure of the third lawn mower detection device is shown schematically. Figure 4 The difference is that Figure 5 The first channel 11 includes a first outlet 1111 of the first liquid collecting section 111 with a spacing therebetween and the first conductive member 21, and a spacing therebetween and the second conductive member 22. When the detection liquid is collected in the first liquid collecting section 111 and a conductive medium is quickly formed in the first liquid collecting section 111, the conductive medium can also be filled into the first outlet 1111 and the second outlet 1121, so that the conductive medium is in contact with the surface of the first conductive member 21 and the surface of the second conductive member 22 at the same time, thereby improving the detection sensitivity of the lawn mower detection device 100 to the detection liquid.

[0152] Compared with the first channel 11 only including the liquid collecting channel (first liquid collecting section 111), when the first channel 11 includes the liquid collecting channel and the connecting channel 113, the detection liquid only needs to flow to the first outlet 1111 and the second outlet 1121, and converge in the connecting channel 113 to form a conductive medium, so that the conductive medium can realize the conductive function of the first conductive member 21 and the second conductive member 22, without the detection liquid converging into a continuous conductive medium in the first liquid collecting section 111, and the conductive medium is simultaneously filled in the first outlet 1111 and the second outlet 1121. In addition, since the connecting channel 113 does not need to be arranged on one side of the detection component in the Y direction, and has a shorter water flow path than the liquid collecting channel (first liquid collecting section 111), therefore, when the first channel 11 includes the liquid collecting channel and the connecting channel 113, the formation time of the conductive medium in the first channel 11 can be shortened, so as to further improve the detection sensitivity of the lawn mower detection device 100 to the detection liquid.

[0153] The structure of the lawn mower detection device 100 is further described below by taking the example that the first channel 11 includes a liquid collecting channel and a connecting channel 113 .

[0154] Figure 6 FIG. 1 shows a schematic diagram of the structure of the first lawn mower detection device at a second viewing angle. Figure 6 As shown, the liquid collecting channel includes the first liquid collecting section 111 mentioned above. The shape of the first liquid collecting section 111 can be referred to the description above, and will not be repeated here. The first liquid collecting section 111 also has a first outlet 1111 and a second outlet 1121. Figure 3 The difference between the first liquid collecting section 111 in the embodiment is that the first outlet 1111 faces the side of the first conductive member 21 away from the second conductive member 22, and the second outlet 1121 faces the side of the second conductive member 22 away from the first conductive member 21. At this time, the first outlet 1111 is spaced from the side of the first conductive member 21 away from the second conductive member 22, and the second outlet 1121 is spaced from the side of the second conductive member 22 away from the first conductive member 21.

[0155] See also Figure 6 As shown, one end of the communication channel 113 is located between the first outlet 1111 and the first conductive member 21 to connect the first outlet 1111, and the other end of the communication channel 113 is located between the second outlet 1121 and the second conductive member 22 to connect the second outlet 1121. Compared with the case where there is no first channel 11 on the converging surface 10, in this embodiment, the middle part, the first end and the second end of the first liquid collecting section 111 restrict the confluence of the detection liquid, which can also ensure that the detection liquid in the first liquid collecting section 111 quickly converges into the communication channel 113 and converges with the detection liquid in the communication channel 113 to form a continuous conductive medium.

[0156] The first outlet 1111 and the second outlet 1121 can be connected through the two ends of the connecting channel 113, so that the detection liquid in the first liquid collecting section 111 converges into the connecting channel 113, and after merging with the detection liquid in the connecting channel 113, a conductive medium that contacts the first conductive member 21 and the second conductive member 22 at the same time can be quickly formed in the connecting channel 113.

[0157] The number of the first liquid collecting sections 111 may be one. Alternatively, in some embodiments, the number of the first liquid collecting sections 111 may also be N, where N is greater than or equal to 2. The N first liquid collecting sections 111 are sequentially arranged on the confluence surface 10 along the X direction, and along the Y direction, the N first liquid collecting sections 111 are sequentially arranged around the same side of the detection component, so that the first outlets 1111 of the N first liquid collecting sections 111 are sequentially arranged along the Y direction on one side of the detection component in the X direction, and the second outlets 1121 of the N first liquid collecting sections 111 are sequentially arranged along the Y direction on the other side of the detection component in the X direction.

[0158] Compared with one first liquid collecting section 111, by setting N first liquid collecting sections 111, more detection liquid located in the peripheral area of ​​the detection component can be converged to the connecting channel 113, thereby increasing the convergence amount of the detection liquid in the connecting channel 113, and shortening the time for forming a conductive medium that is in contact with the first conductive member 21 and the second conductive member 22 at the same time in the connecting channel 113, so as to further speed up the conduction time of the first conductive member 21 and the second conductive member 22, thereby improving the detection sensitivity of the lawn mower detection device 100 to the detection liquid.

[0159] In order to realize the connection between the connecting channel 113 and the first outlets 1111 and the second outlets 1121 of the N first liquid collecting sections 111, one end of the connecting channel 113 can extend along the Y direction to between the first conductive member 21 and the N first outlets 1111 to connect the N first outlets 1111; correspondingly, the other end of the connecting channel 113 can extend along the Y direction to between the first conductive member 21 and the N second outlets 1121 to connect the N second outlets 1121.

[0160] See also Figure 5 As shown, along the Y direction, N first liquid collecting sections 111 are arranged gradually from the edge of the detection component to the middle of the detection component. Compared with the first liquid collecting section 111 being located in the middle of the detection component, when the first liquid collecting section 111 is located at the edge of the detection component, the detection liquid flows into the connecting channel 113 through the first outlet 1111 and the second outlet 1121, which can shorten the time for forming a conductive medium that contacts the first conductive member 21 and the second conductive member 22 in the connecting channel 113. Therefore, by limiting the arrangement position of the N first liquid collecting sections 111 relative to the detection component, while more detection liquid located in the peripheral area of ​​the detection component is flowed into the connecting channel 113, the time for forming a conductive medium that contacts the first conductive member 21 and the second conductive member 22 in the connecting channel 113 can be further shortened, thereby improving the detection sensitivity of the lawn mower detection device 100 to the detection liquid.

[0161] It should be noted that the middle of the detection component can be understood as the middle area of ​​the detection component, rather than the edge of the detection component. The middle of the detection component includes the center of the detection component. The edge of the detection component can be understood as the edge area of ​​the detection component. The edge of the detection component includes the outermost edge of the detection component. The edge of the detection component is arranged around the periphery of the middle of the detection component.

[0162] Figure 7 The partial exploded view of the first lawn mower detection device is schematically shown. Figure 6 and Figure 7As shown, in some embodiments, a portion of the first conductive member 21 and the second conductive member 22 can be inserted into the mounting member 1, and another portion of the first conductive member 21 and the second conductive member 22 can protrude from the mounting member 1 on one side of the return surface, so that the first conductive member 21 and the second conductive member 22 can be installed on the mounting member 1 while being able to facilitate the first conductive member 21 and the second conductive member 22 to contact the detection liquid.

[0163] See also Figure 6 and Figure 7 As shown, at least one of the first conductive member 21 and the second conductive member 22 may be a long strip structure, and the length direction and thickness direction of the long strip structure are both perpendicular to the X direction. Figure 6 As shown, the first conductive member 21 and the second conductive member 22 are both long strip structures. Alternatively, the first conductive member 21 or the second conductive member 22 can be a long strip structure. When the number of the first liquid collecting sections 111 is N, by setting the long strip structure, it can be ensured that the first outlets 1111 and the second outlets 1121 of the N first liquid collecting sections 111 are facing the first conductive member 21 or the second conductive member 22. At the same time, it can also increase the contact area between the first conductive member 21 and the second conductive member 22 and the detection liquid, thereby enhancing the conduction effect of the first conductive member 21 and the second conductive member 22, so as to further improve the detection sensitivity of the lawn mower detection device 100 to the detection liquid.

[0164] It should be noted that when the number of the first liquid collecting section 111 is one, the first conductive member 21 and the second conductive member 22 may also adopt a non-strip structure. For example, the first conductive member 21 and the second conductive member 22 may adopt a cylindrical structure.

[0165] The following uses the example that both the first conductive member 21 and the second conductive member 22 are long strip structures to further illustrate the structure of the lawn mower detection device 100 .

[0166] See also Figure 6 As shown, the first liquid collecting section 111 is a first groove or a concave structure provided on the confluence surface 10. When the first liquid collecting section 111 is a first groove provided on the confluence surface 10, the mounting member 1 has a first separator 12 between adjacent first grooves. Figure 2As shown, along the thickness direction of the mounting member 1, the first partition 12 has a first end 121 and a second end. The thickness direction of the mounting member 1 is the Z direction. The cross-sectional area of ​​the first end 121 is smaller than the cross-sectional area of ​​the second end, and the first end 121 faces the notch of the first groove, so that the first partition 12 can form a tip at the first end 121. The detection liquid is usually in a droplet shape at the notch of the first groove. Due to the presence of the tip, the water film of the detection liquid can be punctured, so that the detection liquid can quickly disperse and converge in the first groove, so as to further shorten the time for forming a conductive medium that is in contact with the first conductive member 21 and the second conductive member 22 at the same time in the connecting channel 113, thereby improving the detection sensitivity of the lawn mower detection device 100 to the detection liquid.

[0167] It should be noted that the cross section where the cross-sectional area of ​​the first end 121 is located and the cross section where the cross-sectional area of ​​the second end is located are formed by two cross sections parallel to each other. The two cross sections are parallel to the XZ plane or the XY plane. The XZ plane is a plane formed by the X direction and the Z direction mentioned above. The XY plane is a plane formed by the X direction and the Y direction mentioned above. The XZ plane is perpendicular to the XY plane.

[0168] The first separator 12 is a strip-shaped triangular prism structure, the smaller end of the triangular prism can form the first end 121 of the first separator 12, and the larger end of the triangular prism can form the second end of the first separator 12. In this way, while ensuring that the mounting member 1 has the first separator 12 between adjacent first grooves, it can ensure that the cross-sectional area of ​​the mounting member 1 at the first end 121 is smaller than the cross-sectional area of ​​the second end.

[0169] It should be noted that after the first liquid collecting section 111 is connected to the connecting channel 113, a closed first channel 11 is formed. By setting the closed first channel 11, it is possible to prevent the detection liquid of the lawn mower 200 from overflowing from around the first liquid collecting section 111 in a sports scene. At this time, the first partition 12 is equivalent to a barrier to prevent the detection liquid from overflowing.

[0170] In some embodiments, if there are no excessive requirements for the lawn mower 200 to detect liquid overflowing from the first liquid collecting section 111 when the lawn mower 200 is in motion, the first channel 11 can also be a non-enclosed structure. In the following, the structure of the lawn mower detection device 100 when the first channel 11 is a non-enclosed structure will be further described in conjunction with specific embodiments.

[0171] Figure 8 The structural diagram of the fourth lawn mower detection device is schematically shown. Fig. 9 The schematic diagram of the structure of the fifth lawn mower detection device is shown schematically. Figure 2The difference is that the first channel 11 shown in the fourth lawn mower detection device and the fifth lawn mower detection device are both non-enclosed structures, and the first liquid collecting section 111 includes a first liquid collecting section 111 and a second liquid collecting section 112.

[0172] The following further describes the differences between the fourth and fifth lawn mower detection devices and the first lawn mower detection device in conjunction with the accompanying drawings.

[0173] See also Figure 8 and Fig. 9 As shown, the first liquid collecting section 111 can be located on the side of the first conductive member 21 away from the second conductive member 22, and the second liquid collecting section 112 is located on the side of the second conductive member 22 away from the first conductive member 21. Since the first conductive member 21 and the second conductive member 22 are arranged at intervals in the X direction, at this time, the first liquid collecting section 111 and the second liquid collecting section 112 are located on both sides of the detection component in the X direction. The first liquid collecting section 111 has a first outlet 1111, and the second liquid collecting section 112 has a second outlet 1121. One end of the communication channel 113 is located between the first outlet 1111 and the first conductive member 21 to connect the first outlet 1111. The other end of the communication channel 113 is located between the second outlet 1121 and the second conductive member 22 to connect the second outlet 1121.

[0174] Compared with the case where there is no first channel 11 on the converging surface 10, in this embodiment, the first liquid collecting section 111 and the second liquid collecting section 112 are arranged, so that the detection liquid can be collected in the first liquid collecting section 111 and the second liquid collecting section 112 to avoid the detection liquid from spreading all over the converging surface 10, so that the detection liquid can be quickly collected into the connecting channel 113 along the first liquid collecting section 111 and the second liquid collecting section 112.

[0175] The first outlet 1111 and the second outlet 1121 can also be connected through the two ends of the connecting channel 113, so that the detection liquid in the first liquid collecting section 111 can be converged into the connecting channel 113 through the first outlet 1111, and the detection liquid in the second liquid collecting section 112 can be converged into the connecting channel 113 through the second outlet 1121, so that the detection liquid in the first liquid collecting section 111 and the second liquid collecting section 112 converge in the connecting channel 113 to form a conductive medium that is in contact with the first conductive member 21 and the second conductive member 22 at the same time, thereby realizing the detection function of the lawn mower detection device 100 for the detection liquid.

[0176] See also Figure 8 and Fig. 9As shown, the first liquid collecting section 111 and the second liquid collecting section 112 may both be recessed structures provided on the converging surface 10, or the first liquid collecting section 111 and the second liquid collecting section 112 may both be grooves provided on the converging surface 10. Compared with the grooves, when the first liquid collecting section 111 and the second liquid collecting section 112 are both recessed structures, by controlling the recessed degree of the recessed structures, while realizing the collecting function of the first liquid collecting section 111 and the second liquid collecting section 112 on the detection liquid, there is no need to make grooves on the converging surface 10, so that the structure of the mounting member 1 can be simplified.

[0177] See also Figure 8 and Fig. 9 As shown, along the projection direction of the converging surface 10 on the mounting member 1, the height of the first liquid collecting section 111 at the first outlet 1111 is lower than the height of the first liquid collecting section 111 at other positions, and the height of the second liquid collecting section 112 at the second outlet 1121 is lower than the height of the second liquid collecting section 112 at other positions, so that the detection liquid can flow in the first liquid collecting section 111 toward the first outlet 1111 under the action of gravity, and the detection liquid can flow in the second liquid collecting section 112 toward the second outlet 1121 under the action of gravity, so that the detection liquid can quickly converge from the first liquid collecting section 111 and the second liquid collecting section 112 to the connecting channel 113 respectively. Among them, the projection direction of the converging surface 10 on the mounting member 1 is perpendicular to the X direction and the Y direction. The projection direction of the converging surface 10 on the mounting member 1 can be parallel to the Z direction.

[0178] It should be noted that, for the first collecting section 111, the following measures can be taken to ensure that along the projection direction of the converging surface 10 on the mounting member 1, the height of the first collecting section 111 at the first outlet 1111 is lower than the height of the first collecting section 111 at other positions, and the height of the second collecting section 112 at the second outlet 1121 is lower than the height of the second collecting section 112 at other positions.

[0179] The following takes the first liquid collecting section 111 as an example for further explanation. Figure 8 As shown, along the water flow direction of the first liquid collecting section 111, when the depression degree or groove depth of the first liquid collecting section 111 at each section is the same, in some embodiments, through the first measure, it can be ensured that along the projection direction of the confluence surface 10 on the mounting member 1, the height of the first liquid collecting section 111 at the first outlet 1111 and the second outlet 1121 are lower than the height of the first liquid collecting section 111 at other positions.

[0180] Among them, the first measure is: the converging surface 10 is tilted in the area corresponding to the first liquid collecting section 111 relative to the area of ​​the converging surface 10 corresponding to the detection component, so that along the projection direction of the converging surface 10 on the mounting member 1, the height of the first liquid collecting section 111 at the first outlet 1111 is lower than the height of the first liquid collecting section 111 at other positions. It should be noted that the tilted setting of the converging surface 10 in the area corresponding to the first liquid collecting section 111 will be further explained in conjunction with specific drawings below, and will not be repeated here.

[0181] Alternatively, when the thickness of the mounting member 1 remains unchanged, in some embodiments, the second measure can ensure that the height of the first liquid collecting section 111 at the first outlet 1111 is lower than the height of the first liquid collecting section 111 at other positions along the converging surface 10 in the projection direction of the mounting member 1.

[0182] Among them, the second measure is: changing the depression degree or groove depth of the first liquid collecting section 111 at each section, so that along the projection direction of the confluence surface 10 on the mounting part 1, the height of the first liquid collecting section 111 at the first outlet 1111 is lower than the height of the first liquid collecting section 111 at other positions.

[0183] See also Figure 8 and Fig. 9 As shown, in some embodiments, the first liquid collecting section 111 and the second liquid collecting section 112 can be arranged on the same side of the detection component in the Y direction. Along the third direction, one end of the first liquid collecting section 111 having the first outlet 1111 extends toward the first conductive member 21, so that the detection liquid cannot converge in a direction other than the third direction. The third direction intersects the X direction and the Y direction. The third direction can refer to the W1 direction or the W2 direction. For example, taking the third direction as the W1 direction as an example, the first liquid collecting section 111 can prevent the detection liquid from converging in the a direction. The a direction is perpendicular to the W1 direction.

[0184] Along the fourth direction, one end of the second liquid collecting section 112 having the second outlet 1121 extends toward the second conductive member 22, so that the detection liquid cannot converge in a direction other than the fourth direction. The fourth direction intersects the X direction and the Y direction, and the fourth direction is different from the third direction. The fourth direction can refer to the V1 direction or the V2 direction. For example, taking the fourth direction as the V1 direction as an example, the second liquid collecting section 112 can prevent the detection liquid from converging in the b direction, etc. The b direction is perpendicular to the V1 direction.

[0185] This can ensure that the detection liquid can only converge along the extension direction of the first liquid collecting section 111 (W1 direction or W2 direction) in the first liquid collecting section 111, and the detection liquid can only converge along the second liquid collecting section 112 (V1 direction or V2 direction) in the second liquid collecting section 112, so that the detection liquid can quickly converge into the connecting channel 113.

[0186] See also Figure 8 and Fig. 9 As shown, the first outlet 1111 faces the end of the first conductive member 21, and the second outlet 1121 faces the end of the second conductive member 22. At this time, there is a gap between the first outlet 1111 and the end of the first conductive member 21, and there is a gap between the second outlet 1121 and the end of the second conductive member 22. The end of the second conductive member 22 and the end of the first conductive member 21 are respectively located in the two ends of the connecting channel 113, so that the detection liquid in the first liquid collecting section 111 and the second liquid collecting section 112 converge into the connecting channel 113, and when a conductive medium that contacts the ends of the first conductive member 21 and the ends of the second conductive member 22 at the same time is formed in the connecting channel 113, the detection liquid can conduct the first conductive member 21 and the second conductive member 22, thereby realizing the detection function of the lawn mower detection device 100 on the detection liquid.

[0187] See also Figure 8 and Fig. 9 As shown, the second liquid collecting section 112 can be symmetrically arranged relative to the first liquid collecting section 111, so that the second liquid collecting section 112 and the first liquid collecting section 111 have substantially equal water flow paths, so that the time for the detection liquid in the second liquid collecting section 112 and the first liquid collecting section 111 to converge into the connecting channel 113 is substantially equal, so as to ensure that the detection liquid can be quickly converged from the second liquid collecting section 112 and the first liquid collecting section 111 to the connecting channel 113 at the same time. The first liquid collecting section 111 and the second liquid collecting section 112 can be symmetrically arranged on both sides of the detection component in the X direction, and both are located on one side of the detection component in the Y direction.

[0188] It should be noted that, in some embodiments, the second liquid collecting section 112 is also asymmetrically arranged relative to the first liquid collecting section 111 .

[0189] The number of the first liquid collecting section 111 and the second liquid collecting section 112 is one. The first liquid collecting section 111 and the second liquid collecting section 112 are both linear channels, and the linear channels are arranged at an angle with the X direction and the Y direction. By setting the linear channels, the water flow path of the detection liquid on the first liquid collecting section 111 and the second liquid collecting section 112 can be further shortened, and the detection sensitivity of the lawn mower detection device 100 to the detection liquid can be improved. For example, when the mounting member 1 is a rectangular structure with corners, the first liquid collecting section 111 and the second liquid collecting section 112 can be arranged at the corners of the mounting member 1, and the first liquid collecting section 111 and the second liquid collecting section 112 can be arranged at the two diagonals of the mounting member 1.

[0190] See also Fig. 9As shown, in some embodiments, the confluence surface 10 may further include a guide channel 13. The guide channel 13 is located in the peripheral area of ​​the detection component, and the first outlet 1111 and the second outlet 1121 are both connected to the guide channel 13. On the basis of the first channel 11, through the setting of the guide channel 13, the detection liquid can be quickly converged into the connecting channel 113 through the first outlet 1111 or the second outlet 1121, and the convergence amount of the detection liquid in the connecting channel 113 can also be increased, and the time for forming a conductive medium that contacts the first conductive member 21 and the second conductive member 22 at the same time in the connecting channel 113 is shortened, so as to further shorten the conduction time of the first conductive member 21 and the second conductive member 22, and improve the detection sensitivity of the lawn mower detection device 100 to the detection liquid.

[0191] See also Fig. 9 As shown, the first outlet 1111 and the second outlet 1121 are both connected to a guide channel 13. The guide channel 13 has an inlet end 131 and an outlet end 132, and the outlet end 132 is connected to the first outlet 1111 or the second outlet 1121 to achieve the connection between the first outlet 1111 or the second outlet 1121 and the guide channel 13.

[0192] See also Fig. 9 As shown, the guide channel 13 connected to the first outlet 1111 can be inclined relative to the first conductive member 21, so that the outlet end 132 is away from the first conductive member 21 and the first liquid collecting section 111, and can extend toward the edge of the confluence surface 10, so as to guide more detection liquid located in the peripheral area of ​​the detection component to the first outlet 1111. Correspondingly, the guide channel 13 connected to the second outlet 1121 can be inclined relative to the second conductive member 22, so that the outlet end 132 is away from the second conductive member 22 and the second liquid collecting section 112, and can extend toward the edge of the confluence surface 10, so as to guide more detection liquid located in the peripheral area of ​​the detection component to the second outlet 1121.

[0193] Fig.10 Shows Figure 8 Cross-section view in the AA direction. Fig. 9 and Fig.10 As shown, along the projection direction of the converging surface 10 on the mounting member 1 (see the Z direction), the height of the guide channel 13 at the inlet end 131 can be higher than the height of the outlet end 132, so that the detection liquid can flow in the guide channel 13 toward the outlet end 132 under the action of gravity, thereby quickly converging into the connecting channel 113 through the first outlet 1111 or the second outlet 1121.

[0194] The flow guiding channel 13 may be a recessed structure or a groove on the converging surface 10 .

[0195] See also Fig.10As shown, along the guide direction of the guide channel 13, when the degree of depression or the depth of the groove of the guide channel 13 at each section is the same, in some embodiments, the thickness of the mounting member 1 can be changed so that the mounting member 1 forms a convex point at the position of the inlet end 131 and a concave point at the position of the outlet end 132, so as to ensure that along the projection direction of the mounting member 1 on the converging surface 10, the height of the guide channel 13 at the inlet end 131 can be higher than the height of the outlet end 132.

[0196] It should be noted that when the thickness of the mounting member 1 remains unchanged, the degree of depression of the guide channel 13 at each section or the depth of the groove can also be changed so that along the projection direction of the confluence surface 10 on the mounting member 1, the height of the guide channel 13 at the inlet end 131 can be higher than the height of the outlet end 132.

[0197] Fig.11 The sixth lawn mower detection device is schematically shown. Figure 7 ) and the fifth lawn mower detection device ( Figure 8 The difference between the sixth lawn mower detection device and the fourth lawn mower detection device is that the first liquid collecting section 111 and the second liquid collecting section 112 in the sixth lawn mower detection device are arranged relative to the detection component and the arrangement position of the guide channel 13. The following, in conjunction with the accompanying drawings, further describes the differences between the sixth lawn mower detection device and the fourth lawn mower detection device and the third lawn mower detection device.

[0198] See also Fig.11 As shown, in some embodiments, the first liquid collecting section 111 and the second liquid collecting section 112 can also be arranged on both sides of the detection component in the X direction. Along the X direction, the first liquid collecting section 111 has one end of the first outlet 1111 extending toward the first conductive member 21, so that the detection liquid cannot converge in a non-X direction. For example, the first liquid collecting section 111 can prevent the detection liquid from converging in the Y direction. Along the X direction, the second liquid collecting section 112 has one end of the second outlet 1121 extending toward the second conductive member 22, so that the detection liquid cannot converge in a non-X direction. For example, the second liquid collecting section 112 can prevent the detection liquid from converging in the Y direction. In this way, the detection liquid can only converge along the extension direction (X direction) of the first liquid collecting section 111 in the first liquid collecting section 111, and the detection liquid can only converge along the extension direction (X direction) of the second liquid collecting section 112 in the second liquid collecting section 112, so that the detection liquid can be quickly gathered in the first liquid collecting section 111 and the second liquid collecting section 112, and converge into the connecting channel 113.

[0199] The first outlet 1111 faces the middle of the first conductive member 21, and the second outlet 1121 faces the middle of the second conductive member 22. When one end of the communication channel 113 is located between the first outlet 1111 and the first conductive member 21 to connect the first outlet 1111, and one end of the communication channel 113 is located between the second outlet 1121 and the second conductive member 22 to connect the second outlet 1121, the first outlet 1111 and the second outlet 1121 can also be connected through the communication channel 113 to achieve the confluence of the detection liquid in the communication channel 113, and form a conductive medium that contacts the first conductive member 21 and the second conductive member 22 at the same time.

[0200] In the present application, there is no particular limitation on the location of the first liquid collecting section 111 and the second liquid collecting section 112 relative to the detection assembly, so that the structure of the first channel 11 and the mounting member 1 can be more diversified to adapt to the design requirements of the lawn mower detection device 100 for different first channels 11.

[0201] See also Fig.11 As shown, the number of the first liquid collecting section 111 and the number of the second liquid collecting section 112 can be one. For the convenience of description, the guide channel 13 connected to the first liquid collecting section 111 is called the first guide channel, and the guide channel 13 connected to the second liquid collecting section 112 is called the second guide channel.

[0202] The first guide channel can be arranged on one side of the detection component in the Y direction and between the first conductive member 21 and the second conductive member 22. The second guide channel can be arranged on the other side of the detection component in the Y direction and between the first conductive member 21 and the second conductive member 22.

[0203] At this time, the communication channel 113 is an annular communication channel, and at least part of the first conductive member 21 and the second conductive member 22 can be located in the annular communication channel. The first guide channel and the second guide channel can both be connected to the first outlet 1111 and the second outlet 1121 through the annular communication channel, so that the detection liquid located in the peripheral area of ​​the detection component is converged into the communication channel 113 through the first guide channel and the second guide channel, which can increase the convergence amount of the detection liquid in the communication channel 113, shorten the time for forming a conductive medium that contacts the first conductive member 21 and the second conductive member 22 at the same time in the communication channel 113, so as to further speed up the conduction time of the first conductive member 21 and the second conductive member 22, and improve the detection sensitivity of the lawn mower detection device 100 to the detection liquid.

[0204] Fig.12 The structural diagram of the seventh lawn mower detection device is schematically shown. Fig.13 The schematic diagram of the structure of the eighth lawn mower detection device is shown schematically. Fig.11The difference between the seventh and eighth lawn mower detection devices is the number of the first liquid collecting section 111, the second liquid collecting section 112 and the flow guide channel 13. The following, in conjunction with the accompanying drawings, further describes the differences between the sixth lawn mower detection device and the third and fourth lawn mower detection devices.

[0205] See also Fig.12 and Fig.13 As shown, the number of the first liquid collecting section 111 and the second liquid collecting section 112 can be multiple. The multiple first liquid collecting sections 111 and the multiple second liquid collecting sections 112 are sequentially arranged on the confluence surface 10 along the direction, so that the first outlets 1111 of the multiple first liquid collecting sections 111 are sequentially arranged along the Y direction on one side of the detection component in the X direction, and the second outlets 1121 of the multiple first liquid collecting sections 111 are sequentially arranged along the Y direction on the other side of the detection component in the X direction.

[0206] Similar to the first lawn mower detection device, the sixth lawn mower detection device can also converge more detection liquid in the peripheral area of ​​the detection component to the connecting channel 113 through the arrangement of multiple first liquid collecting sections 111 and multiple second liquid collecting sections 112, thereby increasing the convergence amount of the detection liquid in the connecting channel 113, shortening the time for forming a conductive medium that is in contact with the first conductive member 21 and the second conductive member 22 at the same time in the connecting channel 113, thereby further shortening the conduction time of the first conductive member 21 and the second conductive member 22, and improving the detection sensitivity of the lawn mower detection device 100 to the detection liquid.

[0207] The first liquid collecting sections 111 and the second liquid collecting sections 112 are symmetrically arranged on both sides of the detection assembly in the X direction. The arrangement of the first liquid collecting sections 111 relative to the detection assembly can be found in the above description of the first lawn mower detection device, and will not be further elaborated here.

[0208] In summary, the lawn mower detection device 100 can collect the detection liquid in the peripheral area of ​​the detection component through the setting of a first channel 11, so as to achieve rapid conduction between the first conductive member 21 and the second conductive member 22 through the detection liquid, thereby improving the detection sensitivity of the lawn mower detection device 100 to the detection liquid.

[0209] In some embodiments, the number of the first channels 11 is not limited to one. For example, in some embodiments, the number of the first channels 11 can also be two. The two first channels 11 are arranged on both sides of the mounting member 1 in the Y direction. In this way, while ensuring that the two first channels 11 are arranged in the peripheral area of ​​the detection component, the detection liquid in the peripheral area of ​​the detection component can be collected through the two first channels 11, so as to further improve the conduction rate of the first conductive member 21 and the second conductive member 22, and improve the detection sensitivity of the lawn mower detection device 100 to the detection liquid.

[0210] For example, see Figure 6 , Figure 8 , Fig. 9 and Fig.13 As shown, the number of the first channels 11 can be two. When the two first channels 11 are arranged on both sides of the mounting member 1 in the Y direction, the connecting channels 113 in the two first channels 11 can be connected to each other to form an annular connecting channel in the circumferential direction of the detection component, so that the detection liquid in the first liquid collecting section 111 and the second liquid collecting section 112 of the two first channels 11 can converge into the annular connecting channel to further increase the convergence amount of the detection liquid in the annular connecting channel, improve the conduction rate of the first conductive member 21 and the second conductive member 22, and improve the detection sensitivity of the lawn mower detection device 100 to the detection liquid.

[0211] See also Figure 6 , Figure 8 , Fig. 9 , Figures 11 to 13 As shown, the busbar 10 may include a horizontal plane 15 and a guide surface. The guide surface is arranged on at least a part of the circumference of the horizontal plane 15. The guide surface may include two first guide surfaces 16. The first conductive member 21 and the second conductive member 22 are arranged on the horizontal plane 15 at intervals along the X direction to realize the arrangement of the first conductive member 21 and the second conductive member 22 on the busbar 10.

[0212] Along the X direction, the two first flow guide surfaces 16 are obliquely arranged on both sides of the horizontal plane 15. The first flow guide surfaces 16 are used to guide the detection liquid to the horizontal plane 15. Part of the first channel 11 is arranged on the two first flow guide surfaces 16, and the two first channels 11 are symmetrically arranged on both sides of the mounting member 1 in the Y direction, so that the two first channels 11 are arranged on the converging surface 10, and the detection liquid located in the peripheral area of ​​the detection component can be guided to one side of the horizontal plane 15 through the two first flow guide surfaces 16, so that more detection liquid can be converged to the connecting channel 113, so as to further increase the convergence amount of the detection liquid in the connecting channel 113, improve the conduction rate of the first conductive member 21 and the second conductive member 22, and improve the detection sensitivity of the lawn mower detection device 100 to the detection liquid.

[0213] The connecting channel 113 may be disposed at the connection between the first guide surface 16 and the horizontal surface 15 , and at least a portion of the liquid collecting channel may be disposed on the two first guide surfaces 16 , so that a portion of the first channel 11 is disposed on the two first guide surfaces 16 .

[0214] Fig.14 Shows Figure 7 Local cross-section diagram in the BB direction. Fig.14 Only a partial view of the first liquid collecting section 111 on the side of the first outlet 1111 is shown. The structure of the first liquid collecting section 111 on the side of the second outlet 1121 is symmetrical to that on the side of the first outlet 1111.

[0215] See also Figure 6 and Fig.14 As shown, when the liquid collecting channel includes the first liquid collecting section 111, the middle area of ​​the first liquid collecting section 111 can be located in the horizontal plane 15, and the areas of the first liquid collecting section 111 having the first outlet 1111 and the second outlet 1121 can be respectively arranged on the two first flow guiding surfaces 16, so that part of the liquid collecting channel can be arranged on the two first flow guiding surfaces 16. In this case, the first outlet 1111 and the second outlet 1121 can be respectively located on one side of the two first flow guiding surfaces 16 adjacent to the horizontal plane 15. Fig.14 As shown, the side of the first guide surface 16 adjacent to the horizontal plane 15 is a low position on the converging surface 10, and the side of the first guide surface 16 away from the horizontal plane 15 is a high position on the converging surface 10. Therefore, when the first outlet 1111 and the second outlet 1121 are respectively located on the side of the two first guide surfaces 16 adjacent to the horizontal plane 15, and the first outlet 1111 and the second outlet 1121 are both located at a low position on the converging surface 10, it is convenient for the detection liquid to slide to the first outlet 1111 or the second outlet 1121 by its own gravity and flow back into the connecting channel 113.

[0216] See also Figure 6 As shown, when the number of the first liquid collecting sections 111 is N, since the N first liquid collecting sections 111 are arranged gradually from the edge of the detection component to the middle of the detection component, and the two first channels 11 are symmetrically arranged on both sides of the mounting member 1 in the Y direction, the two first channels 11 can collect more detection liquid located in the peripheral area of ​​the detection component to improve the detection sensitivity of the lawn mower detection device 100 to the detection liquid.

[0217] See also Figure 8 , Fig. 9 , Figures 11 to 13As shown, when the liquid collecting channel includes the first liquid collecting section 111 and the second liquid collecting section 112, the first liquid collecting section 111 can be located on one first guide surface 16, and the second liquid collecting section 112 can be located on another first guide surface 16. Since the first guide surface 16 is tilted relative to the horizontal plane 15, and the first liquid collecting section 111 is located on one guide surface, the confluence surface 10 is tilted in the area corresponding to the first liquid collecting section 111 relative to the confluence surface 10 in the area corresponding to the detection component, so that along the projection direction of the confluence surface 10 on the mounting member 1, the height of the first liquid collecting section 111 at the first outlet 1111 is lower than the height of the first liquid collecting section 111 at other positions. Specifically, the first outlet 1111 can be located on the side of the first guide surface 16 adjacent to the horizontal plane 15, so that the first outlet 1111 is at a lower position on the confluence surface 10, which can facilitate the detection liquid in the first liquid collecting section 111 to slide to the first outlet 1111 by its own gravity and converge into the connecting channel 113.

[0218] Similarly, since the second liquid collecting section 112 is located on another guide surface, the confluence surface 10 is tilted in the area corresponding to the second liquid collecting section 112 relative to the area corresponding to the detection component, so that the height of the second liquid collecting section 112 at the second outlet 1121 along the projection direction of the confluence surface 10 on the mounting member 1 is lower than the height of the second liquid collecting section 112 at other positions. Specifically, the second outlet 1121 can be located on the side of the second guide surface 17 adjacent to the horizontal plane 15, so that the second outlet 1121 is at a lower position on the confluence surface 10, which can facilitate the detection liquid in the second liquid collecting section 112 to slide to the second outlet 1121 by its own gravity and converge into the connecting channel 113.

[0219] See also Figure 8 , Fig. 9 , Figures 11 to 13As shown, in some embodiments, the guide surface may further include a second guide surface 17. The second guide surface 17 is connected between the first guide surface 16 and the horizontal plane 15. The second guide surface 17 is inclined relative to the horizontal plane 15, and the second guide surface 17 is used to guide the detection liquid to the horizontal plane 15. At this time, the two first guide surfaces 16, the two second guide surfaces 17 and the horizontal plane 15 can form a concave converging surface, and the first guide surface 16 and the second guide surface 17 are arranged around the side of the horizontal plane 15, and form a slope surface of the concave converging surface, and the area where the horizontal plane 15 is located is the lowest area of ​​the concave converging surface. Due to the existence of the slope surface, the detection liquid located in the peripheral area of ​​the detection component can be quickly guided to one side of the horizontal plane 15 through the first guide surface 16 and the second guide surface 17, so that more detection liquid can flow into the connecting channel 113, so as to further increase the convergence amount of the detection liquid in the connecting channel 113, improve the conduction rate of the first conductive member 21 and the second conductive member 22, and improve the detection sensitivity of the lawn mower detection device 100 to the detection liquid.

[0220] It should be noted that the concave collecting surface can be understood as a collecting surface 10 that is recessed toward the inside of the mounting member 1 .

[0221] See also Figure 8 and Fig. 9 As shown, in some embodiments, part of the first channel 11 may be disposed on a side of the first guide surface 16 adjacent to the second guide surface 17. That is, the first liquid collecting section 111 and the second liquid collecting section 112 may be disposed on a side of the first guide surface 16 adjacent to the second guide surface 17. By further limiting the position of part of the first channel 11, the first guide surface 16 and the second guide surface 17 guide the detection liquid to one side of the horizontal plane 15, so that the detection liquid converges to the connecting channel 113, so as to further increase the convergence amount of the detection liquid in the connecting channel 113, improve the conduction rate of the first conductive member 21 and the second conductive member 22, and improve the detection sensitivity of the lawn mower detection device 100 to the detection liquid.

[0222] See also Figures 11 to 13 As shown, in some embodiments, the guide channel 13 can also be located on the second guide surface 17, and the outlet end 132 of the guide channel 13 is located on the side of the second guide surface 17 adjacent to the horizontal plane 15, so that the outlet end 132 is lower than the inlet end 131, so that the detection liquid can rely on its own gravity to quickly converge into the connecting channel 113 (annular connecting channel).

[0223] It should be noted that, in order to prevent the setting of the guide surface from affecting the overall thickness of the mounting member 1, in the Z direction, the side of the mounting member 1 opposite to the converging surface 10 can be set to a contoured structure that is the same as or similar to the outer edge contour of the guide surface.

[0224] In some embodiments, a second channel 14 may be further provided on the confluence surface 10, and the second channel 14 is used to collect the detection liquid, so that on the basis of the first channel 11, the second channel 14 can collect the detection liquid between the first conductive member 21 and the second conductive member 22, and the detection liquid can form another continuous conductive medium in the second channel 14. When the conductive medium is filled in the two ends of the second channel 14 and contacts the surfaces of the first conductive member 21 and the second conductive member 22 at the same time, the detection sensitivity of the lawn mower detection device 100 to the detection liquid can be further improved.

[0225] The following is Fig.11 Taking the sixth lawn mower detection device as an example, the structure of the lawn mower detection device 100 is further described.

[0226] See also Fig.11 As shown, the second channel 14 is located in the area surrounded by the first conductive member 21 and the second conductive member 22, and along the X direction, the two ports of the second channel 14 extend to the surface of the first conductive member 21 and the surface of the second conductive member 22 respectively, so that the detection liquid cannot converge in a non-X direction. For example, the second channel 14 can prevent the detection liquid from converging in the Y direction. In this way, the detection liquid between the first conductive member 21 and the second conductive member 22 can be quickly gathered in the second channel 14, and another continuous conductive medium is formed in the second channel 14. When this conductive medium is filled to the two ports of the second channel 14 and contacts the surface of the first conductive member 21 and the surface of the second conductive member 22 at the same time, it can also conduct the surface of the first conductive member 21 and the second conductive member 22.

[0227] Therefore, based on the first channel 11, the present application sets the second channel 14 so that the detection liquid on the confluence surface 10 can contact the surface of the first conductive member 21 and the second conductive member 22 from different directions at the same time, thereby further improving the detection sensitivity of the lawn mower detection device 100 to the detection liquid. At the same time, it can also enhance the conduction effect between the first conductive member 21 and the second conductive member 22, thereby enhancing the detection stability of the lawn mower detection device 100 to the detection liquid.

[0228] The number of the second channel 14 may be one. Fig.11 As shown, the number of the second channels 14 can also be multiple (including two). In the present application, the number of the second channels 14 is not particularly limited. The following takes the number of the second channels 14 as an example to further illustrate the structure of the lawn mower detection device 100.

[0229] Fig.15 Shows Figure 7 Magnified view at C. See Fig.15As shown, along the Y direction, the plurality of second channels 14 are spaced apart on the busbar 10, so that the two ends of the plurality of second channels 14 can be sequentially arranged between the first conductive member 21 and the second conductive member 22 along the Y direction. At the same time, the plurality of second channels 14 can be distributed between the first conductive member 21 and the second conductive member 22 in a relatively uniform manner, so as to improve the collection capacity of the plurality of second channels 14 for the detection liquid, so that a plurality of conductive media that are in contact with the first conductive member 21 and the second conductive member 22 at the same time can be formed between the first conductive member 21 and the second conductive member 22, so as to further improve the detection sensitivity of the lawn mower detection device 100 to the detection liquid, and enhance the detection stability of the lawn mower detection device 100 to the detection liquid.

[0230] See also Fig.15 As shown, the second channel 14 is a second groove provided on the converging surface 10. The second groove is a linear groove to shorten the flow path of the detection liquid in the second channel 14 so as to quickly conduct the first conductive member 21 and the second conductive member 22.

[0231] The mounting member 1 has a second partition 18 between adjacent second grooves. Along the Z direction, the second partition 18 has a third end 181 and a fourth end, the cross-sectional area of ​​the third end 181 is smaller than the cross-sectional area of ​​the fourth end, and the third end 181 faces the notch of the second groove, so that the second partition 18 can also form a tip at the first end 121. Similarly, due to the presence of the tip, the water film of the detection liquid can be pierced, so that the detection liquid can quickly disperse and converge in the second groove, so as to further shorten the time for forming a conductive medium that contacts the first conductive member 21 and the second conductive member 22 at the same time in the second channel 14, thereby improving the detection sensitivity of the lawn mower detection device 100 to the detection liquid.

[0232] The structure of the second separator 18 is the same as that of the first separator 12. The cross section where the cross-sectional area of ​​the third end 181 is located and the cross section where the cross-sectional area of ​​the fourth end is located can also be formed by the two parallel cross sections mentioned above. The structure of the second separator 18 and the two parallel cross sections can refer to the relevant description of the first separator 12 above, and no further details will be given here.

[0233] Fig.16 The structure diagram of the ninth lawn mower detection device is schematically shown. Fig.16As shown, in some embodiments, if only one first channel 11 is provided on the converging surface 10, the mounting member 1 may further be provided with a water collecting trough 4 on the converging surface 10. The water collecting trough 4 is connected to the first channel 11, and a portion of at least one of the first conductive member 21 and the second conductive member 22 is located in the water collecting trough 4, so that the detection liquid collected in the water collecting trough 4 can be converged into the first channel 11, so that the first conductive member 21 and the second conductive member 22 are quickly connected. In addition, since a portion of at least one of the first conductive member 21 and the second conductive member 22 is located in the water collecting trough 4, the conduction area of ​​the first conductive member 21 and the second conductive member 22 can also be increased, so as to further enhance the detection stability of the detection liquid by the lawn mower detection device 100.

[0234] Fig.16 2 shows the structure of the lawn mower detection device 100 when parts of the first conductive member 21 and the second conductive member 22 are both located in the water collection tank 4. In some embodiments, parts of the first conductive member 21 or parts of the second conductive member 22 may also be located in the water collection tank 4.

[0235] The water collecting trough 4 can be in a racetrack shape, an elliptical shape, a rectangular shape, etc. In the present application, the structure of the water collecting trough 4 is not particularly limited. It should be noted that the water collecting trough 4 can be connected to the connecting channel 113 of the first channel 11. When the first conductive member 21 is a long strip structure, the end of the first conductive member 21 away from the first channel 11 can extend to the outside of the connecting channel 113 and be located in the water collecting trough 4, so that part of the first conductive member 21 is located in the water collecting trough 4. Similarly, when the second conductive member 22 is a long strip structure, the end of the second conductive member 22 away from the first channel 11 can extend to the outside of the connecting channel 113 and be located in the water collecting trough 4, so that part of the second conductive member 22 is located in the water collecting trough 4.

[0236] In some embodiments, the surfaces of the first conductive member 21 and the second conductive member 22 facing the first channel 11 and the second channel 14 are both electrical contact surfaces, so as to ensure that when the detection liquid in the first channel 11 and the second channel 14 are in contact with the first conductive member 21 and the second conductive member 22 at the same time, the first conductive member 21 and the second conductive member 22 can be connected, so as to realize the detection function of the lawn mower detection device 100 for the detection liquid.

[0237] The lawn mower 200 generally includes a traveling mechanism, a driving assembly engine and a blade cutting assembly.

[0238] On the basis of the above, the embodiment of the present application further provides a lawn mower 200. The structure of the lawn mower 200 is further described below in conjunction with specific drawings.

[0239] Fig.17 Schematically shows a partial schematic diagram of a lawn mower 200. Fig.17As shown, the lawn mower 200 comprises a housing 210 , a control assembly and any one of the above lawn mower detection devices 100 . The housing 210 may comprise a bottom housing 211 and an upper cover 212 , wherein the upper cover 212 is disposed on the bottom housing 211 .

[0240] Fig.18 for Fig.17 Enlarged partial cross-sectional view in the DD direction. Fig.18 As shown, the housing 210 includes a mounting groove 213, and the mounting groove 213 includes an opening 2131. The lawn mower detection device 100 is disposed in the mounting groove 213 through the opening 2131, and the confluence surface 10 is exposed on the housing 210, so that when the lawn mower detection device 100 is installed on the housing 210, detection liquid such as rainwater can fall on the confluence surface 10, thereby realizing the detection function of the lawn mower detection device 100 on the detection liquid.

[0241] Specifically, the mounting groove 213 can be located on a side of the upper cover 212 away from the bottom shell 211 (the upper surface of the upper cover 212), so that the lawn mower detection device 100 can be located at a higher position of the shell 210, so that the confluence surface 10 can converge more detection liquid, so as to achieve the detection sensitivity of the lawn mower detection device 100 to the detection liquid.

[0242] The control component is electrically connected to the detection component so that when the lawn mower detection device 100 detects rainwater or other detection liquid on the confluence surface 10, the control component can control the start and stop state of the drive component, thereby adjusting the lawn mower to stop mowing while controlling the movement of the walking mechanism to drive the lawn mower to move and return to the base station to avoid rain.

[0243] It should be noted that the walking mechanism, the driving assembly and the cutting assembly can all be installed on the side of the bottom shell 211 away from the upper cover 212. The specific installation method and position of the walking mechanism, the driving assembly and the cutting assembly on the bottom shell 211 can refer to the structure of the lawn mower 200 in the related art, and will not be further described here.

[0244] See also Fig.18 As shown, in some embodiments, when the lawn mower detection device 100 is disposed in the installation groove 213, there is a distance between the lawn mower detection device 100 and the opening 2131 to prevent the detection liquid on the confluence surface 10 from overflowing to the outside of the installation groove 213 through the opening 2131 when the lawn mower 200 is moving, thereby affecting the detection sensitivity of the lawn mower detection device 100 to the detection liquid.
