Technical Field

[0001] This utility model relates to the field of garden tools technology, specifically to an intelligent lawnmower. Background Technology

[0002] Smart lawnmowers are common gardening tools used for mowing various types of lawns. To cope with the complex working environment of garden lawns, existing smart lawnmowers are equipped with radar, panoramic cameras, and other optical detection devices. If an obstacle is detected, it will perform obstacle avoidance maneuvers. However, during the mowing process, grass clippings and dust inevitably fall onto the optical detection devices, causing them to be blocked and unable to function properly, forcing the machine to stop. Furthermore, existing smart lawnmowers are prone to water accumulation during operation, which can affect their normal use. Utility Model Content

[0003] In view of this, the present invention provides an intelligent lawnmower to solve the problems of grass clippings and dust falling onto the optical detection device during the mowing process in existing intelligent lawnmowers, as well as the problem of water accumulating inside the intelligent lawnmower.

[0004] This utility model provides an intelligent lawnmower, comprising: Optical inspection device; The main body has a mounting base on the top for mounting optical detection devices and a drainage hole at the bottom. The decorative cover is connected to the mounting base and / or the body, and forms a mounting cavity with the mounting base to accommodate the optical detection device. The decorative cover has an opening for the probe of the optical detection device to extend out. A blower is used to blow air onto the surface of the probe; a guide section is connected to the mounting cavity and extends through the body in the height direction to the drain hole, forming a liquid flow path guided from the opening on the decorative cover to the drain hole.

[0005] Beneficial effects: The air blowing device installed inside the mounting cavity generates airflow that blows onto the probe surface when the optical inspection device is operating. This prevents interference from grass clippings, dust, and other debris, avoiding misjudgments caused by these obstructions and malfunctions. Furthermore, the drainage section guides rainwater entering the mounting cavity through the opening to the drain hole for timely discharge, preventing water accumulation inside the machine and its impact on normal operation and lifespan.

[0006] In one alternative embodiment, the bottom of the mounting base is provided with a drain hole, which is connected to a drainage hole.

[0007] Beneficial effect: Water entering the mounting base can be promptly discharged through the drain hole at the bottom of the mounting base.

[0008] In one alternative embodiment, the flow guide includes a first inclined flow guide wall disposed between the drain hole and the drain outlet.

[0009] Beneficial effects: By setting a first inclined guide wall between the drain hole and the drainage hole, water can be quickly guided to the drainage hole, reducing the retention time of water accumulation and improving drainage efficiency.

[0010] In one alternative implementation, the first inclined guide wall is integrally injection molded with the body.

[0011] Beneficial effects: The first inclined guide wall is integrally injection molded with the machine body, which is convenient for processing and forming. Moreover, the first inclined guide wall is formed by utilizing part of the side wall of the machine body, without the need for additional structures, thus achieving the purpose of simplifying the structure.

[0012] In one alternative embodiment, the guide portion further includes a drain channel, wherein the bottom wall of the mounting base portion extends downward to form a drain channel, and a drain hole is disposed at the bottom of the drain channel.

[0013] Beneficial effects: By setting a drainage channel at the bottom of the mounting base, the water accumulated in the mounting cavity can be collected in the lower drainage channel and discharged from the drain hole at the bottom of the drainage channel, which improves drainage efficiency and effectively avoids the problem of water accumulation. In addition, the downward extension of the drainage channel can also reduce the distance between the drain hole and the drain outlet, avoiding the problem of excessive drainage noise caused by a large drop.

[0014] In one optional embodiment, the flow guide further includes: The second inclined guide wall is formed by the bottom wall of the mounting base gradually tilting downwards from the side away from the drain hole towards the side closer to the drain hole.

[0015] Beneficial effects: The second inclined guide wall can quickly guide the water flow to concentrate in the lower water hole, reduce the retention time of water accumulation, and improve drainage efficiency.

[0016] In one alternative implementation, a portion of the bottom wall of the body is recessed downwards to form an arc-shaped drainage cavity, with a drainage hole located at the bottom of the arc-shaped drainage cavity.

[0017] Beneficial effects: The arc-shaped drainage chamber set on the bottom wall of the machine allows water to collect in the lower arc-shaped drainage chamber and be discharged from the drainage hole at the bottom of the arc-shaped drainage chamber, which is more efficient and can effectively avoid the problem of water residue. In addition, the arc-shaped drainage chamber design can also reduce the accumulation of debris such as leaves and mud near the drainage hole.

[0018] In one alternative embodiment, the blowing device includes: An airflow drive component is installed inside the mounting cavity; The air duct has an air duct inlet and an air duct outlet, with the air duct outlet surrounding the outer periphery of the probe and communicating with the opening; The airflow drive component is located at the air duct inlet, which is suitable for driving the airflow from the air duct inlet into the air duct and blowing it onto the surface of the probe through the air duct outlet; The bottom wall of the air duct is equipped with a drain outlet, and the inner cavity of the air duct forms part of the flow guide section.

[0019] Beneficial effects: The designed air duct directs the airflow generated by the airflow drive to the surface of the probe. Furthermore, the design of the air duct outlet surrounding the outer perimeter of the probe ensures that the airflow from the outlet blows across the entire surface of the probe, creating a 360° airflow without blind spots and providing better protection against obstructions. Drainage outlets on the bottom wall of the air duct allow rainwater and debris entering the duct to flow out into the mounting cavity outside the duct, preventing the accumulation of debris and rainwater inside the duct.

[0020] In one optional implementation, the smart lawnmower further includes: An opening is provided on the body and / or the mounting base, the opening connecting the mounting cavity and the external space.

[0021] Beneficial effects: Through the openings on the body and / or mounting base, air can enter from the opening on the rear side of the smart lawnmower, and then be blown out from the probe of the optical detection device via the blower. The mounting cavity can not only serve as an independent chamber for installing the optical detection device and the blower, but also as an air duct for air intake and exhaust. On the one hand, it provides an air source for the blower, and on the other hand, it can serve as a heat dissipation duct for the blower and other electronic components inside the body, eliminating the need for an additional cooling fan. This simplifies the structure, reduces the complexity, size and power consumption of the entire machine, and is more conducive to cost reduction and product miniaturization.

[0022] In one alternative implementation, the smart lawnmower has a windward side and a leeward side along its direction of travel. The opening is located on the leeward side, the airflow drive component is located on the leeward side, the body includes the fuselage and the cover, the cover is placed on the fuselage, and an air intake channel communicating with the mounting cavity is formed between the fuselage and the cover located on the leeward side. A filter structure is installed inside the air inlet channel or at the opening.

[0023] Beneficial effects: By placing the opening on the leeward side, the user cannot see the opening from the front, improving the aesthetics of the smart lawnmower. The opening can also serve as an air inlet, allowing air to enter from the leeward side. By placing the airflow drive component on the leeward side, it is possible to effectively prevent grass clippings and dust raised during lawnmower operation from being sucked into the airflow drive component, causing blockages or wear. Furthermore, the air intake channel formed between the body and the casing on the leeward side allows air to enter from the leeward side of the lawnmower. The filter structure set at the air intake channel or opening can also filter the airflow, further preventing grass clippings and dust from being sucked into the airflow drive component.

[0030] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0031] The following is combined with Figures 1 to 11 The following describes embodiments of the present invention.

[0032] According to an embodiment of the present invention, the present invention provides an intelligent lawnmower, including an optical detection device 1, a body 2, a decorative cover 3, a blower 4, and a guide section. The top of the body 2 is provided with a mounting base 21 for mounting the optical detection device 1, and the bottom of the body 2 is provided with a drain hole 200. The decorative cover 3 is connected to the mounting base 21 and / or the body 2, and together with the mounting base 21, forms a mounting cavity for accommodating the optical detection device 1. The decorative cover 3 is provided with an opening for the probe portion 11 of the optical detection device 1 to extend out. The blower 4 is used to blow air onto the surface of the probe portion 11. Preferably, the blower 4 is disposed in the mounting cavity. The guide section communicates with the mounting cavity and penetrates the body along the height direction to extend to the drain hole 200, forming a liquid flow path guided from the opening on the decorative cover 3 to the drain hole 200.

[0033] In the above embodiment, the blowing device 4 installed inside the mounting cavity generates airflow when the optical detection device 1 is working, blowing it onto the surface of the probe portion 11. This prevents the optical detection device 1 from being interfered with by grass clippings, dust, and other debris during operation, avoiding misjudgments caused by grass clippings and dust obscuring the device and preventing the entire machine from malfunctioning. Furthermore, the guide section guides rainwater entering the mounting cavity from the opening to the drain hole 200, ensuring timely drainage and preventing rainwater accumulation inside the machine, which could affect its normal operation and service life.

[0034] Based on the above embodiments, as a further defined embodiment, the optical detection device 1 includes, but is not limited to, radar and panoramic camera. Preferably, the optical detection device 1 is radar, including lidar and ultrasonic radar. More preferably, the optical detection device 1 is lidar. The mounting base 21 is integrally formed with the body 2. The mounting base 21 has a mounting groove with a top opening 201. The decorative cover 3 is a cover structure that covers the optical detection device 1. The decorative cover is detachably connected to the mounting base 21 and / or the body 2. Optionally, the decorative cover is snapped and fixed to the mounting base 21. The optical detection device 1 includes a main body and a probe part 11 disposed on the top of the main body. Preferably, the main body is columnar and the probe part 11 is hemispherical. The top of the decorative cover 3 has an opening for the probe part 11 of the optical detection device 1 to extend out. The main body is located inside the mounting cavity, and the probe part 11 is located outside the mounting cavity and extends out of the body 2.

[0035] In one alternative implementation, such as Figure 6 As shown, the bottom of the mounting base 21 is provided with a drain hole 210, which is connected to the drain hole 200.

[0036] In the above embodiment, the water that enters the mounting base 21 can be discharged in a timely manner through the drain hole 210 provided at the bottom of the mounting base 21 and the drain hole 200.

[0037] In one alternative implementation, such as Figure 6 and Figure 7 As shown, the flow guide includes a first inclined flow guide wall 202 disposed between the drain hole 210 and the drain hole 200.

[0038] In the above embodiment, by providing a first inclined guide wall 202 between the drain hole 210 and the drainage hole 200, water can be quickly guided to the drainage hole 200, reducing the retention time of water accumulation and improving drainage efficiency.

[0039] In one alternative embodiment, the first inclined guide wall 202 is formed by bending a portion of the side wall of the body 2 inwards towards the interior of the body 2.

[0040] In the above embodiment, the first inclined guide wall 202 is integrally injection molded with the body 2, which is convenient for processing and forming. Moreover, the first inclined guide wall 202 is formed by using part of the side wall of the body 2, without the need for additional structures, thus achieving the purpose of simplifying the structure.

[0041] In one alternative embodiment, the guide portion further includes a drain channel 211, the bottom wall of the mounting base 21 is recessed downward to form the drain channel 211, and the drain hole 210 is provided at the bottom of the drain channel 211.

[0042] In the above embodiment, by providing a drain channel 211 at the bottom of the mounting base 21, the water accumulated in the mounting cavity can be gathered into the lower drain channel 211 and discharged from the drain hole 210 at the bottom of the drain channel 211, which improves drainage efficiency and effectively avoids the problem of water accumulation. Moreover, the downward extension of the drain channel 211 can also reduce the distance between the drain hole 210 and the drain hole 200, avoiding the problem of loud drainage noise caused by a large drop.

[0043] Specifically, the drainage channel 211 is designed with a narrow diameter along the water flow direction. The narrow diameter drainage channel 211 can reduce turbulence and eddy currents during fluid flow, and the narrow diameter design can maintain a high water flow velocity, preventing the deposition of particles such as silt due to insufficient flow velocity and reducing the risk of blockage.

[0044] Optionally, the drainage channel 211 includes a first channel and a second channel arranged sequentially along the water flow direction, the inner diameter of the second channel is smaller than the inner diameter of the first channel, and the drainage hole 210 is located on the bottom wall of the first channel.

[0045] In one optional embodiment, the flow guide further includes a second inclined flow guide wall, which is formed by the bottom wall of the mounting base 21 extending downwards from the side away from the drain hole 210 towards the drain hole 210. The second inclined flow guide wall allows water to be quickly guided to the drain hole 210, reducing the retention time of accumulated water and improving drainage efficiency.

[0046] In one alternative implementation, such as Figure 6 and Figure 7 As shown, part of the bottom wall of the body 2 is recessed downward to form an arc-shaped drainage cavity 203, and the drainage hole 200 is located at the bottom of the arc-shaped drainage cavity 203.

[0047] In the above embodiment, by providing an arc-shaped drainage cavity 203 on the bottom wall of the body 2, the accumulated water can be gathered into the arc-shaped drainage cavity 203 at a lower position and discharged from the drainage hole 200 at the bottom of the arc-shaped drainage cavity 203. The drainage efficiency is higher, which can effectively avoid the problem of water residue. In addition, the arc-shaped drainage cavity design can also reduce the accumulation of debris such as leaves and mud near the drainage hole 200.

[0048] Specifically, the arc-shaped drainage cavity 203 is semi-cylindrical, and the drainage hole 200 is located at the lowest position of the arc-shaped drainage cavity 203. The arc-shaped drainage cavity 203 can be formed in one piece and is not prone to the accumulation of impurities. The first inclined guide wall 202 is located between the arc-shaped drainage cavity 203 and the drain hole 210, and the first inclined guide wall 202 is integrally connected with the arc-shaped drainage cavity 203.

[0049] In one optional embodiment, the blowing device 4 includes an airflow drive 41 and an air duct 400. The airflow drive 41 is disposed within the mounting cavity. The air duct 400 has an air duct inlet 401 and an air duct outlet 402, with the air duct outlet 402 surrounding the outer periphery of the probe portion 11. The airflow drive 41 is disposed at the air duct inlet 401 and is adapted to drive airflow from the air duct inlet 401 into the air duct 400 and blow it onto the surface of the probe portion 11 through the air duct outlet 402. A drain outlet is provided on the bottom wall of the air duct 400, which connects the inner cavity of the air duct 400 and the mounting cavity. The inner cavity of the air duct 400 constitutes part of the structure of the guide section.

[0050] In the above embodiment, the air duct 400 can directionally guide the airflow generated by the airflow drive 41 to the surface of the probe portion 11. Furthermore, by employing a design where the air duct outlet 402 surrounds the outer periphery of the probe portion 11, the air exiting the air duct outlet 402 can blow from all sides of the probe portion 11 to the entire surface of the probe portion 11, forming a 360° airflow without blind spots, resulting in better protection against foreign object obstruction. The drain outlet provided on the bottom wall of the air duct 400 allows rainwater and debris entering the air duct 400 to flow through the drain outlet into the mounting cavity outside the air duct 400, preventing debris and rainwater from accumulating inside the air duct 400.

[0051] Based on the above embodiments, as a further defined embodiment, the airflow drive component 41 includes, but is not limited to, a fan, blower, impeller, blower, and air compressor. The air outlet of the airflow drive component 41 is sealed and connected to the air duct inlet 401. The air duct outlet 402 can be an integral annular opening, or it can be a plurality of openings spaced apart circumferentially along the probe portion 11. Preferably, the air duct outlet 402 is an integral annular opening.

[0052] In one optional embodiment, the drain outlet includes a first drain outlet 403, which is disposed on the side of the bottom wall of the air duct 400 away from the air duct inlet 401, and the bottom wall of the air duct 400 gradually slopes downward from the air duct inlet 401 toward the first drain outlet 403.

[0053] In the above embodiment, by setting the bottom wall of the air duct 400 to gradually slope downward from the air duct inlet 401 to the first drain outlet 403, rainwater and debris entering the air duct 400 are directed towards the first drain outlet 403 as much as possible, so as to avoid the airflow drive member 41 flowing towards the air duct inlet 401 side and damaging the air duct inlet 401.

[0054] In one alternative embodiment, the drain outlet includes a second drain outlet 404, which is disposed on the bottom wall of the air duct 400 on the side near the air duct inlet 401.

[0055] In the above embodiment, by providing a drain outlet on each side of the air duct 400, one near the air duct inlet 401 and one far from the air duct inlet 401, debris and rainwater entering the air duct 400 can be quickly discharged to the outside through the two drain outlets, thereby improving the drainage efficiency of the air duct 400 and further preventing the accumulation of debris and rainwater.

[0056] Based on the above embodiments, as a further defined embodiment, the second drain outlet 404 is correspondingly located below the air duct outlet 402, and the air duct inlet 401 is located on the side of the second drain outlet 404 away from the optical detection device 1. The air duct inlet 401 is away from the air duct outlet 402. This design allows rainwater, impurities and other accumulated materials entering from the air duct outlet 402 to flow directly downwards and be discharged from the second drain outlet 404.

[0057] In one alternative implementation, the airflow drive 41 is waterproof; optionally, the airflow drive 41 is a waterproof fan.

[0058] Based on the above embodiments, as a further defined embodiment, the airflow drive component 41 is a fan, and the air outlet of the airflow drive component 41 is sealed and connected to the air duct inlet 401.

[0059] In one alternative implementation, such as Figure 1 and Figure 2 , Figure 5 As shown, along the direction of travel of the intelligent lawnmower, the intelligent lawnmower has a windward side and a leeward side; the air duct inlet 401 is located on the bottom wall of the air duct 400 and is located on the side closer to the windward side; a baffle 421 is also provided on the bottom wall of the air duct 400, and the baffle 421 is separated between the air duct inlet 401 and the second drain outlet 404. In the above embodiment, by setting the air duct inlet 401 on the side close to the windward side, it is convenient to install the airflow drive component 41 on the side close to the air inlet. Furthermore, by setting the baffle 421 between the air duct inlet 401 and the second drain outlet 404, it is convenient for the accumulated impurities to flow along the baffle 421 to the second drain outlet 404 and be discharged. In addition, the baffle 421 can also guide the airflow, so that the air entering from the air duct inlet 401 can be directed to the air duct outlet 402, avoiding the phenomenon that the air entering from the air duct inlet 401 is directly discharged from the second drain outlet 404.

[0060] Based on the above embodiments, as a further defined embodiment, the second drain outlet 404 is correspondingly located below the air duct outlet 402, and the air duct inlet 401 is located on the side of the second drain outlet 404 away from the optical detection device 1. The air duct inlet 401 is away from the air duct outlet 402. This design allows rainwater, impurities and other accumulated materials entering from the air duct outlet 402 to flow directly downwards and be discharged from the second drain outlet 404.

[0061] Based on the above implementation method, as a further defined implementation method, the side wall of the baffle 421 near the air duct inlet 401 is an inclined air guide surface, which can guide the air upward and blow it out from the air duct outlet 402.

[0062] Based on the above embodiments, as a further defined embodiment, the blower 4 also includes a filter screen 44, which is disposed between the air duct inlet 401 and the air duct outlet 402. The filter screen 44 can intercept impurities and effectively prevent impurities entering from the air duct inlet 401 from flowing to the airflow drive component 41, thereby preventing related safety hazards.

[0063] Based on the above embodiments, as a further defined embodiment, the filter screen 44 is disposed in the air duct 400 near the windward side. Preferably, the filter screen 44 is mounted on the baffle 421, which has an L-shaped mounting body with a longitudinal cross section. The bottom of the filter screen 44 is supported and mounted in the mounting groove formed in the mounting body, which provides higher stability. The top of the filter screen 44 extends to a position that abuts against the inner wall surface of the outer side wall of the air duct 400, which can effectively intercept foreign objects.

[0064] Based on the above embodiments, as a further defined embodiment, the filter screen 44 is snap-fitted to the baffle 421 for easy disassembly and secure fixation. As an alternative embodiment, the filter screen 44 is interference-fitted between the baffle 421 and the air duct 400.

[0065] In one optional embodiment, the intelligent lawnmower further includes an opening 201, which is disposed on the body 2 and / or the mounting base 21, and the opening 201 connects the mounting cavity to the external space. Through the opening 201 on the body 2 and / or the mounting base 21, air can enter from the opening 201 on the rear side of the intelligent lawnmower, and then be blown out from the probe portion 11 of the optical detection device 1 via the blower 4. The mounting cavity can not only serve as an independent chamber for mounting the optical detection device 1 and the blower 4, but also as an air duct 400 for air intake, providing an air source for the blower 4 and also serving as a heat dissipation duct 400 for cooling the blower 4 and other electronic components inside the body 2. This eliminates the need for an additional cooling fan, thereby simplifying the structure and reducing the complexity, size, and power consumption of the entire machine, which is more conducive to cost reduction and product miniaturization.

[0066] In one optional embodiment, the airflow drive 41 is disposed on the side of the mounting cavity near the windward side; the air outlet of the airflow drive 41 is connected to the air duct inlet 401, and the air inlet of the airflow drive 41 is connected to the mounting cavity.

[0067] In the above embodiment, the airflow drive component 41 is disposed on the side of the mounting cavity near the windward side, which facilitates the airflow drive component 41 to take in air. At the same time, the air entering the mounting cavity from the air inlet of the decorative cover 3 can also pass through the airflow drive component 41 first, resulting in a better cooling and heat dissipation effect on the airflow drive component 41.

[0068] In other alternative implementations, such as Figure 10 and Figure 1 As shown, the opening 201 is located on the leeward side, the airflow drive component 41 is located on the leeward side, the body 2 includes the body 22 and the cover 23, the cover 23 covers the body 22, and an air inlet channel communicating with the mounting cavity is formed between the body 22 and the cover 23 located on the leeward side; a filter structure 24 is provided in the air inlet channel or at the opening 201.

[0069] In the above embodiment, by placing the opening 201 on the leeward side, the user cannot see the opening 201 from the front, which improves the aesthetics of the smart lawnmower. The opening 201 can also serve as an air inlet to allow air to enter from the leeward side. By placing the airflow drive component 41 on the leeward side, it is possible to effectively prevent grass clippings and dust and other debris raised during the operation of the lawnmower from being sucked into the airflow drive component 41, which could cause blockage or wear. Furthermore, the air intake channel formed between the body 22 and the cover 23 on the leeward side allows air to enter from the leeward side of the lawnmower. The filter structure 24 provided at the air intake channel or the opening 201 can play a filtering role, further preventing grass clippings and dust and other debris from being sucked into the airflow drive component 41.

[0070] Optionally, the filter structure 24 is made of sponge, which can not only play an effective filtering role, but also achieve a flexible connection between the body 22 and the cover 23, reducing frictional damage between the two.

[0071] In one alternative embodiment, the mounting base 21 includes a leeward sidewall located on the leeward side; the opening 201 is a notch structure provided on the leeward sidewall, and the notch structure penetrates the top and bottom surfaces of the leeward sidewall.

[0072] In the above embodiment, the opening 201 is designed with a notch structure, which facilitates processing and forming. By setting the notch structure to penetrate the top and bottom surfaces of the leeward sidewall, the bottom edge of the opening 201 extends to the bottom wall of the mounting cavity. When rainwater enters the mounting cavity, the rainwater can be directly discharged through the opening 201, so that the opening 201 can also serve as a drainage outlet, further simplifying the structure.

[0073] Based on the above embodiments, as a further defined embodiment, the leeward sidewall constitutes the rear wall of the body 2. Along the length direction of the leeward sidewall, a notch is provided in the middle part of the leeward sidewall to form an opening 201. The shape of the opening 201 is adapted to the shape of the bottom wall of the mounting base 21. The bottom edge of the opening 201 is on the same horizontal plane as the bottom wall of the mounting base 21 and will not obstruct the mounting cavity.

[0074] In one alternative implementation, such as Figure 7 As shown, the decorative cover 3 has an air inlet grille 301 on its windward side, and the grille gap of the air inlet grille 301 forms an air inlet that communicates with the mounting cavity.

[0075] In the above embodiment, by setting the air inlet grille 301 and using the gap of the air inlet grille 301 as the air inlet, foreign objects can be blocked, and large impurities can be prevented from entering the installation cavity from the air inlet.

[0076] Based on the above embodiments, as a further defined embodiment, the air intake grille 301 and the decorative cover 3 are integrally formed, and the air intake grille 301 is an arc shape that is recessed into the mounting cavity.

[0077] In an alternative embodiment, the blower 4 further includes a fixed bracket 43, on which the airflow drive 41 is detachably mounted, and the fixed bracket 43 is fixed to the mounting base 21.

[0078] In the above embodiment, the fixed bracket 43 facilitates the installation of the airflow drive component 41.

[0079] Based on the above embodiments, as a further defined embodiment, the airflow drive component 41 is provided with positioning holes, the fixed bracket 43 is provided with positioning ribs, and the fixed bracket 43 is also provided with buckles. During assembly, positioning is achieved by the insertion and cooperation of the positioning ribs and positioning holes, and then the airflow drive component 41 is secured by the buckles on the fixed bracket 43, so that the fixed bracket 43 and the airflow drive component 41 are fixed together, and then the two are installed together in the mounting base 21 of the body 2. Optionally, the fixed bracket 43 and the mounting base 21 are fixed with screws.

[0080] In one alternative embodiment, the air duct 400 has an annular air duct housing 42, which is fitted over the optical detection device 1; the air duct outlet 402 is an annular opening provided on the top of the air duct housing 42, and the annular air duct outlet 402 extends obliquely toward the center of the probe portion 11.

[0081] In the above embodiment, the air duct 400 adopts the design of the air duct shell 42 and is wrapped around the optical detection device 1. This not only makes the overall structure more compact, but also forms a fully enclosed surrounding air outlet effect on the outer periphery of the optical detection device 1. Moreover, the air duct outlet 402 extends obliquely towards the center of the probe part 11, so that the air coming out of the air duct outlet 402 can blow onto the entire outer surface of the probe part 11.

[0082] In one alternative embodiment, the duct housing 42 includes an inner wall, an outer wall, and a bottom wall connecting the inner wall and the outer wall; the outer wall is tapered from bottom to top, and there is an annular gap between the top edge of the outer wall and the top edge of the inner wall, the annular gap forming the duct outlet 402.

[0083] In the above embodiment, the outer wall adopts a design that gradually narrows from bottom to top, which makes the flow surface of the entire air duct 400 cavity gradually decrease from the air duct inlet 401 to the air duct outlet 402, thereby increasing the pressure at the air duct outlet 402 and increasing the air outlet speed. The air duct outlet 402 is formed by the annular gap between the top edge of the outer wall and the top edge of the inner wall of the air duct housing 42, without the need for additional openings.

[0084] Based on the above implementation method, as a further limiting implementation method, the annular gap is less than 2mm. This design can effectively prevent large impurities from entering the air duct 400.

[0085] Based on the above embodiments, as a further defined embodiment, both the inner and outer sidewalls are annular, and the top edges of the annular inner and outer sidewalls extend inclined toward the center to form an air duct outlet 402 that is inclined toward the center of the probe portion 11.

[0086] In one optional embodiment, the outer periphery of the air duct housing 42 is provided with an outward protrusion 422, and the air duct inlet 401 is provided on the bottom wall of the outward protrusion 422.

[0087] In the above embodiment, the external protrusion 422 is provided, and the air duct inlet 401 is provided on the bottom wall of the external protrusion 422, which facilitates the installation of the airflow drive component 41.

[0088] In one alternative embodiment, the outlet end of the air duct 400 extends between the opening of the decorative cover 3 and the probe portion 11, and is snapped and fixed to the decorative cover 3. In the above embodiment, the air duct outlet 402 extends into the gap between the opening of the decorative cover 3 and the probe part 11, which facilitates blowing air into the probe part 11. Furthermore, by snapping the outlet end of the air duct 400 to the decorative cover 3, the stability of the structure of the air duct 400 and the decorative cover 3 can be further improved.

[0089] In one alternative embodiment, the smart lawnmower also includes a radar mount 5, an optical detection device 1 detachably mounted on the radar mount 5, the radar mount 5 being fixed within the mounting base 21, and an air duct 400 detachably mounted on the radar mount 5.

[0090] In the above embodiment, the radar mounting base 5 facilitates the installation of the optical detection device 1, and the air duct 400 is detachably installed on the radar mounting base 5 so that the air duct 400, the radar mounting base 5, and the optical detection device 1 are assembled as one unit, which facilitates the overall disassembly and maintenance.

[0091] Based on the above embodiments, as a further defined embodiment, the intelligent lawnmower also includes a radar pad 6, and the optical detection device 1 is mounted on the radar mounting base 5 through the radar pad 6, which reduces wear between the optical detection device 1 and the radar mounting base 5, and at the same time can reduce vibration.

[0092] Based on the above embodiments, as a further defined embodiment, the bottom of the air duct 400 is fixed to the radar mounting base 5 by screws, and the optical detection device 1 is also fixed to the radar mounting base 5 by screws.

[0093] The specific structure, working principle, and assembly process of the intelligent lawnmower provided in this embodiment are as follows: In this embodiment, the airflow drive component 41 is fixed to the main unit via a mounting bracket 43. Simultaneously, the optical detection device 1 is fixed to the radar mounting base 5 via a radar pad 6 using four screws. The air duct housing 42 is also fixed to the radar mounting base 5 with screws, thus fixing the relative positions of the lidar and the air duct housing 42. Finally, the radar mounting base 5 is also fixed to the main unit with screws, thus fixing the relative positions of the airflow drive component 41, the air duct housing 42, and the optical detection device 1.

[0094] The specific assembly process is as follows: the airflow drive component 41 and the fixed bracket 43 are positioned through the positioning holes on the airflow drive component 41, and the fixed bracket 43 is fastened to the airflow drive component 41 with a buckle, and then they are installed together on the body 2; the optical detection device 1 and the radar pad 6 are fixed to the radar mounting base 5 with screws at the bottom, and they are fixed together on the body 2, and their relative positions with the airflow drive component 41 and the fixed bracket 43 are fixed; then the air duct housing 42 is assembled, and the air duct housing 42 is fixed to the radar mounting base 5 with screws; finally, the decorative cover 3 is assembled on the body 2 and together with the air duct housing 42 forms the air duct 400. The decorative cover 3 forms a protective cover, and the side of the decorative cover 3 is provided with an air inlet. When the machine starts, the airflow drive 41 delivers air to the surface of the optical detection device 1 through the air duct housing 42. This prevents grass clippings and dust from falling onto the lidar during operation, which could interfere with the machine's recognition and cause it to stop, thus halting the operation of the airflow drive 41. In this application, the air duct housing 42 adopts a front-high-rear-low design, allowing incoming rainwater and debris to flow backward as much as possible, preventing them from flowing towards the front airflow drive 41. Simultaneously, the air duct housing 42 has a drain outlet at both the front and rear. This allows debris and rainwater entering the air duct 400 to flow into the mounting cavity and then out through the drain hole 200 at the bottom of the housing, preventing the accumulation of debris and rainwater. Furthermore, a filter screen 44 intercepts impurities, effectively preventing grass clippings and dust from falling onto the optical detection device 1 during operation and causing it to malfunction.

[0095] This application adds an independent airflow drive component 41 and an air duct 400 inside the body 2. When the optical detection device 1 is working, the airflow drive component 41 is energized to generate air, which is delivered to the surface of the optical detection device 1 through the air duct 400, so that the optical detection device 1 is not disturbed by grass clippings and dust when it is working.

[0096] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the protection scope of the embodiments of this application.
