[0001] This disclosure claims priority to two Chinese patent applications filed on March 30, 2025, entitled "A Heat Dissipation Device for a Lawnmower Battery Compartment" and on May 15, 2025, entitled "A Air Supply Structure for a Lawnmower Air Duct". The entire contents of these patent applications are incorporated herein by reference. Technical Field

[0002] This application relates to the field of lawn mowing equipment technology, and more particularly to a lawn mowing device. Background Technology

[0003] Lawn mowing equipment is widely used for mowing lawns, parks, and other vegetated areas. In related technologies, lawn mowing equipment typically relies on the airflow generated by the rotation of the cutting device (such as blades) to transport and discharge the resulting grass clippings along a discharge channel. This method of grass clipping transport, based on the airflow generated by the rotation of the cutting device, can meet basic discharge requirements under light loads and relatively dry grass clippings. However, under heavy loads or wet grass cutting conditions, the increased amount or weight of grass clippings in the airflow channel increases, enhancing the obstruction of airflow and leading to a decrease in the efficiency of grass clipping transport within the airflow channel. Summary of the Invention

[0004] To overcome the problems existing in related technologies, this specification provides a lawn mowing device. This device generates supplementary airflow through an airflow generator, which merges and superimposes with the cutting airflow generated by the cutting device within the lawn discharge channel before being discharged together. This improves the airflow capacity of the lawn discharge channel and enhances the conveying and discharge of grass clippings.

[0005] According to a first aspect of the embodiments of this specification, a lawn mowing device is provided, the lawn mowing device comprising: The casing includes the grass-draining channel; A cutting device is mounted on the housing and is used to perform cutting operations. When the cutting device performs cutting operations, it generates a cutting airflow, which is discharged through the grass discharge channel. The lawn mowing equipment also includes: An airflow generator is disposed on the housing, and the airflow generator is configured to generate supplementary airflow, which is discharged through the straw discharge channel; The airflow generating device and the cutting device are configured to be driven by different driving devices.

[0006] In this embodiment, when the mowing equipment is working, the cutting device performs the cutting operation under the drive of its corresponding drive device, and generates a cutting airflow during the operation. The cutting airflow is discharged through the grass discharge channel of the housing. At the same time, the airflow generator operates under the drive of a different drive device than the cutting device to generate a supplementary airflow, which is also discharged through the grass discharge channel. Since the cutting airflow and the supplementary airflow flow together and merge in the grass discharge channel, they are superimposed in the grass discharge channel to form a composite discharge airflow, which is discharged through the grass discharge channel.

[0007] By setting the airflow generator and the cutting device to be driven by different drive devices, the supplementary airflow can provide airflow support independently of the cutting device and superimpose with the cutting airflow formed by the cutting device in the grass discharge channel, thereby improving the airflow supply capacity and discharge stability in the grass discharge channel. This is beneficial to enhance the conveying and discharge effect of grass clippings, especially in working conditions where the grass discharge resistance increases, such as when cutting large loads or wet grass, it can reduce the risk of poor grass discharge and accumulation.

[0008] In some embodiments of this disclosure, based on the foregoing scheme, the cutting device is driven by a first motor; the airflow generating device is driven by a second motor.

[0009] In this embodiment, when the mowing equipment is working, the first motor drives the cutting device to perform the cutting operation and generates a cutting airflow during the cutting process. The cutting airflow is discharged through the grass discharge channel. At the same time, the second motor drives the airflow generator to generate a supplementary airflow. The supplementary airflow is discharged through the grass discharge channel and merges and superimposes with the cutting airflow in the grass discharge channel before being discharged together.

[0010] By driving the cutting device and the airflow generator with the first motor and the second motor respectively, the generation of supplementary airflow is independent of the driving of the cutting device. This allows for the provision of a stable supplementary airflow even when the cutting load increases or the cutting airflow weakens. The supplementary airflow is superimposed on the cutting airflow to enhance the airflow support in the grass discharge channel, thereby improving the stability of grass clipping conveying and discharge.

[0011] In some embodiments of this disclosure, based on the aforementioned scheme, the housing is constructed with a cutting cavity, the cutting device is disposed in the cutting cavity, and the cutting cavity is connected to the grass discharge channel.

[0012] In this embodiment, the first motor drives the cutting device to operate in the cutting cavity to perform the cutting operation. When the cutting device operates, a cutting airflow is generated in the cutting cavity. Since the cutting cavity is connected to the grass discharge channel, the cutting airflow and the grass clippings it carries enter the grass discharge channel from the cutting cavity and are discharged. At the same time, the supplementary airflow generated by the airflow generator is also discharged through the grass discharge channel and merges and superimposes with the cutting airflow in the grass discharge channel.

[0013] By setting a cutting cavity inside the housing and connecting the cutting cavity with the grass discharge channel, the airflow and grass clippings generated by the cutting device have a clear flow path, which can reduce the disorderly retention of grass clippings inside the housing and improve the smoothness of grass clippings entering the grass discharge channel. Furthermore, the superposition of the cutting airflow and the supplementary airflow in the grass discharge channel is beneficial to enhancing the airflow support and discharge stability of the grass discharge channel.

[0014] In some embodiments of this disclosure, based on the foregoing scheme, the lawn mowing device further includes: A battery pack is installed inside the housing, the battery pack including a battery casing and battery cells disposed inside the battery casing; A control device, installed within the housing, is configured to control the operation of the lawn mowing equipment.

[0015] In this embodiment, the battery pack is installed inside the housing, and the battery cells are installed inside the battery housing to power the lawn mowing equipment; the control device is also installed inside the housing to control the operation of the lawn mowing equipment, so as to realize the scheduling and control of the working status of the cutting device and the airflow generating device.

[0016] By integrating the battery pack and control device into the housing, it is convenient to centrally arrange and protect the power supply and control unit, which helps to improve the overall compactness and rationality of the machine structure. At the same time, the control device is used to control the operation of the mowing equipment, which can realize the coordinated control of the cutting operation and the process of generating supplementary airflow, thereby improving the stability and adaptability of the equipment operation.

[0017] In some embodiments of this disclosure, based on the foregoing scheme, the supplementary airflow and / or the cutting airflow flows through the battery pack.

[0018] In this embodiment, when the mowing equipment is working, the supplementary airflow generated by the airflow generator and / or the cutting airflow formed by the cutting device flows along a preset airflow path, passes through the battery pack during the flow, and then enters the grass discharge channel and is discharged.

[0019] By allowing supplemental and / or cutting airflow to flow through the battery pack, the airflow can be used to exchange heat and dissipate heat from the battery pack, which helps to reduce the temperature rise of the battery pack and improve power supply stability. At the same time, the airflow continues to enter the grass discharge channel and is discharged without affecting the grass discharge function of the grass discharge channel, thus realizing the reuse of heat dissipation and grass discharge airflow.

[0020] In some embodiments of this disclosure, based on the foregoing scheme, the supplementary airflow and / or the cutting airflow flows through the control device.

[0021] In this embodiment, when the mowing equipment is working, the supplementary airflow generated by the airflow generator and / or the cutting airflow formed by the cutting device flow along a preset airflow path, and during the flow, it flows through the control device, and then enters the grass discharge channel and is discharged.

[0022] By allowing the supplemental airflow and / or cutting airflow to flow through the control device, the airflow can be used to exchange heat with the control device, which helps to reduce the temperature rise of the control device and improve the working stability of the control unit; at the same time, the airflow continues to be discharged through the grass discharge channel, realizing the reuse of heat dissipation and grass discharge airflow.

[0023] In some embodiments of this disclosure, based on the foregoing scheme, the supplementary airflow flows through at least one of the battery pack and the control device.

[0024] In this embodiment, when the mowing equipment is working, the supplementary airflow generated by the airflow generator flows along a preset airflow path and passes through at least one of the battery pack and control device during the flow, and then enters the grass discharge channel and is discharged.

[0025] By allowing the supplemental airflow to flow through at least one of the battery pack and control device, the supplemental airflow can be used to exchange heat and dissipate heat on the corresponding heat-generating components, which helps to reduce the temperature rise of the heat-generating components and improve the operational stability of the mowing equipment; at the same time, the supplemental airflow continues to be discharged through the grass discharge channel, realizing the reuse of heat dissipation and grass discharge airflow.

[0026] In some embodiments of this disclosure, based on the foregoing scheme, the supplementary airflow includes a first airflow and a second airflow; The first airflow passes through at least one of the battery pack and the control device, and the second airflow passes through at least the other of the battery pack and the control device.

[0027] In this embodiment, the supplementary airflow generated by the airflow generator includes a first airflow and a second airflow. During operation, the first airflow flows along the first airflow path and passes through at least one of the battery pack and the control device, while the second airflow flows along the second airflow path and passes through at least the other of the battery pack and the control device. Subsequently, the first airflow and the second airflow enter the grass discharge channel and are discharged, and can merge and superimpose with the cutting airflow generated by the cutting device within the grass discharge channel.

[0028] By dividing the supplementary airflow into a first airflow and a second airflow, and allowing them to flow through the battery pack and control device respectively, it is beneficial to divert and dissipate heat from different heat-generating components, thereby improving the heat dissipation coverage and heat dissipation balance. At the same time, the first airflow and the second airflow enter the grass discharge channel and are discharged and merged and superimposed with the cutting airflow, which can provide more sufficient airflow support for the grass discharge channel.

[0029] In some embodiments of this disclosure, based on the foregoing solution, a heat dissipation vent is constructed on the battery casing; The housing has a makeup air inlet corresponding to the heat dissipation vent; The makeup air inlet is located on at least one of the flow paths of the makeup airflow.

[0030] In this embodiment, the battery casing has a heat dissipation vent, and the casing is provided with a corresponding air intake. During operation, the supplementary airflow flows along a preset airflow path, and the air intake is located on at least one supplementary airflow path, allowing air to enter through the air intake and flow into the battery casing through the heat dissipation vent, then exit from the battery casing and continue to flow along the supplementary airflow path, finally entering the weed discharge channel for discharge.

[0031] By setting up a supplementary air inlet corresponding to the heat dissipation vent and placing it in the path of the supplementary airflow, a stable air intake channel can be provided for the battery pack using the supplementary airflow, which is beneficial to enhancing the heat exchange and heat dissipation effect of the battery pack. At the same time, after completing the heat dissipation of the battery pack, the supplementary airflow can still be used for discharge through the grass discharge channel, realizing the synergistic reuse of heat dissipation and supplementary airflow.

[0032] In some embodiments of this disclosure, based on the foregoing scheme, the supplementary airflow includes a first airflow; The first airflow passes through at least one of the battery pack and the control device; The airflow generating device includes: The air supply fan blades are configured to be driven to rotate by the second motor; The first channel is configured to guide the first airflow through it, and the first channel connects the make-up air inlet and the air inlet side of the make-up air fan blade.

[0033] In this embodiment, the second motor drives the supplementary air fan blades to rotate, causing the airflow generator to produce a first airflow in the supplementary airflow. The first airflow flows under the guidance of the first channel, which connects the supplementary air inlet and the air inlet side of the supplementary air fan blades, allowing air to enter through the supplementary air inlet and pass through the first channel under the suction action of the supplementary air fan blades. During this process, the first airflow flows through at least one of the battery pack and the control device, and then the first airflow enters the grass discharge channel and is discharged.

[0034] By driving the air supply fan blades to rotate via the second motor and cooperating with the first channel to connect the air supply inlet and the air supply fan blade inlet side, the first airflow can be stably formed and flow along a preset path. This is beneficial for providing air supply support while allowing the first airflow to cover the battery pack and / or control device for heat exchange and dissipation, thereby improving the operational stability of the equipment under continuous operating conditions.

[0035] In some embodiments of this disclosure, based on the foregoing scheme, a mounting portion is constructed on the housing, and the control device is mounted on the mounting portion; and at least a portion of the mounting portion is located on the flow path of the second airflow.

[0036] In this embodiment, a mounting portion is constructed on the housing, and the control device is mounted on the mounting portion. During operation, the second airflow in the supplementary airflow flows along the path of the second airflow, and at least part of the mounting portion is located on the path through which the second airflow passes, so that the second airflow flows through the mounting portion during its flow and dissipates heat from the control device mounted on the mounting portion. Subsequently, the second airflow enters the grass discharge channel and is discharged.

[0037] By installing the control device on the mounting part located in the path of the second airflow, the second airflow can directly exchange heat with the control device, which helps to reduce the temperature rise of the control device and improve the working stability of the control unit; at the same time, the second airflow continues to be discharged through the grass discharge channel, realizing the synergistic reuse of heat dissipation and air supply.

[0038] In some embodiments of this disclosure, based on the foregoing scheme, the airflow generating device further includes a second channel; The second channel is configured to guide the second airflow through it.

[0039] In this embodiment, when the mowing equipment is working, the second airflow in the supplementary airflow flows along a preset path under the guidance of the second channel, and is discharged after entering the grass discharge channel through the second channel.

[0040] By setting up a second channel to guide the second airflow, the second airflow can flow stably along a preset path, making it easier to cover the target component area with the second airflow and finally guide it into the drainage channel for discharge, thereby improving the utilization efficiency and path controllability of the supplementary airflow.

[0041] In some embodiments of this disclosure, based on the foregoing scheme, the housing includes a cut-out housing and an mounting housing; The cutting housing includes a first sub-housing, and the mounting housing includes a second sub-housing corresponding to the first sub-housing; The first sub-shell and the second sub-shell together enclose the second channel.

[0042] In this embodiment, the housing includes a cutting housing and an installation housing. The cutting housing includes a first sub-housing, and the installation housing includes a second sub-housing corresponding to the first sub-housing. After the cutting housing and the installation housing are assembled, the first sub-housing and the second sub-housing together form a second channel, allowing the second airflow to flow along a preset path within the second channel and be guided to the grass discharge channel for discharge.

[0043] By forming a second channel by enclosing the first sub-shell and the second sub-shell, the structured flow of the second airflow can be guided without adding additional independent pipeline components. This facilitates the formation accuracy and assembly stability of the second channel, thereby improving the controllability and utilization efficiency of the second airflow path.

[0044] In some embodiments of this disclosure, based on the foregoing scheme, the first sub-shell is a first wall panel that protrudes from the surface of the cut shell; The second sub-shell is a second wall panel that protrudes from the surface of the mounting shell; The first wall panel and the second wall panel together form the second channel.

[0045] In this embodiment, the first sub-shell is a first wall panel protruding from the surface of the cutting shell, and the second sub-shell is a second wall panel protruding from the surface of the mounting shell. After the cutting shell and the mounting shell are assembled, the first wall panel and the second wall panel cooperate with each other to form a second channel, allowing the second airflow to flow along a preset path within the second channel and be guided to the grass discharge channel for discharge.

[0046] By setting the first sub-shell and the second sub-shell as protruding wall panel structures and enclosing them to form the second channel, a stable flow guiding boundary can be directly constructed on the shell surface, reducing the dependence of channel forming on independent pipe components, which is beneficial to improving the structural strength and assembly consistency of the second channel, thereby improving the stability of the second airflow guidance.

[0047] In some embodiments of this disclosure, based on the foregoing scheme, the housing includes a cut-out housing and an mounting housing; The cutting housing includes a first sub-housing; The mounting housing includes a second sub-housing corresponding to the first sub-housing; The first sub-shell and the second sub-shell together form the second channel, and the first sub-shell and the second sub-shell are integrally formed.

[0048] In this embodiment, the first sub-shell and the second sub-shell together form the second channel, and the first sub-shell and the second sub-shell are integrally formed, so that the second channel is formed synchronously during the shell forming process, and the second airflow can flow along a preset path in the second channel and be guided to the grass discharge channel for discharge.

[0049] By integrally molding the first sub-shell and the second sub-shell, the number of components can be reduced and the accumulation of assembly tolerances can be decreased. This is beneficial to improving the molding consistency and sealing of the second channel, thereby improving the stability and controllability of the second airflow guidance.

[0050] In some embodiments of this disclosure, based on the foregoing scheme, the housing includes a cut-out housing and an mounting housing; The cutting housing includes a first sub-housing, and the mounting housing includes a second sub-housing corresponding to the first sub-housing; The first sub-shell and the second sub-shell are configured to enclose the second channel with the mounting shell when the cutting shell is assembled with the mounting shell.

[0051] In this embodiment, the first sub-shell is configured to cooperate with the second sub-shell corresponding to the installation shell during the assembly of the cutting shell and the installation shell, and to form a second channel, so that the second airflow can flow along a preset path in the second channel and be guided to the grass discharge channel for discharge.

[0052] By using the first sub-shell and the corresponding second sub-shell in the assembly state to form a second channel, a guide path for the second airflow can be constructed without adding independent air guide components. This simplifies the structure and improves the assembly adaptability of the channel forming, thereby enhancing the stability of the second airflow guidance.

[0053] In some embodiments of this disclosure, based on the foregoing scheme, the first sub-shell is a wall panel protruding from the surface of the cutting shell, and the wall panel is snapped onto or abuts against the surface of the mounting shell near the cutting shell.

[0054] In this embodiment, the first sub-shell is a wall panel that protrudes from the surface of the cutting shell. The wall panel is configured to snap onto or abut against the surface of the mounting shell near the cutting shell after the cutting shell and the mounting shell are assembled, thereby cooperating with the mounting shell to form the guiding boundary of the second channel, so that the second airflow can flow along the preset path of the second channel and be guided to the grass discharge channel for discharge.

[0055] By setting the first sub-shell as a wall panel structure that can snap onto or abut against the surface of the mounting shell, a stable channel boundary can be formed in the assembled state and the reliability of channel formation can be improved, which helps to reduce airflow leakage and improve the stability of the second airflow guide.

[0056] In some embodiments of this disclosure, based on the foregoing scheme, the supplementary airflow further includes a second airflow; The first airflow and the second airflow converge on the air inlet side of the make-up air fan blade; or the first airflow and the second airflow converge upstream on the air inlet side of the make-up air fan blade.

[0057] In this embodiment, the supplementary airflow includes a second airflow in addition to the first airflow. During operation, the first airflow and the second airflow flow along their respective airflow paths and converge on the air intake side of the supplementary airflow fan blade; or, the first airflow and the second airflow converge upstream of the air intake side of the supplementary airflow fan blade and then flow together toward the air intake side of the supplementary airflow fan blade, so that they are drawn in by the supplementary airflow fan blade and further guided into the grass discharge channel for discharge.

[0058] By converging the first airflow and the second airflow on the air intake side of the supplementary air fan or upstream of it, the two airflows can be combined before entering the supplementary air fan, which helps to improve the gathering efficiency and air supply stability of the supplementary airflow, thereby providing more stable airflow support for the subsequent introduction of the grass discharge channel.

[0059] In some embodiments of this disclosure, based on the aforementioned scheme, the grass discharge channel has a grass discharge outlet; The cutting airflow and the first airflow converge at the grass discharge outlet; or, the cutting airflow and the first airflow converge upstream of the grass discharge outlet.

[0060] In this embodiment, the grass discharge channel has a grass discharge outlet. During operation, the cutting airflow generated by the cutting device and the first airflow in the supplementary airflow flow along their respective paths and converge at the grass discharge outlet before being discharged together; or, the cutting airflow and the first airflow converge upstream of the grass discharge outlet and flow along the grass discharge channel to the grass discharge outlet before being discharged.

[0061] By limiting the convergence point of the cutting airflow and the first airflow to the discharge port or upstream of the discharge port, the supplementary airflow can be superimposed on the cutting airflow at or before the end of the discharge channel, which helps to enhance the airflow support at the discharge port and improve the stability of grass clipping discharge.

[0062] In some embodiments of this disclosure, based on the foregoing scheme, the housing includes a cutting housing and a supplementary housing connected to the cutting housing; The cutting housing is provided with an air inlet, a grass discharge channel, and a cutting cavity; the supplementary air housing and the cutting housing together form a supplementary air channel; The second motor and the air supply fan blades are located inside the air supply channel.

[0063] In this embodiment, the housing includes a cutting housing and a supplementary air housing connected to the cutting housing. The cutting housing is constructed with an air inlet, a straw discharge channel, and a cutting cavity. The supplementary air housing and the cutting housing cooperate with each other to form a supplementary air channel. A second motor and a supplementary air fan blade are disposed in the supplementary air channel. The second motor drives the supplementary air fan blade to rotate so that the supplementary airflow flows along the supplementary air channel and is discharged through the straw discharge channel.

[0064] By forming the air supply channel together with the air supply housing and the cutting housing, and arranging the second motor and the air supply fan blades inside the air supply channel, the supplementary airflow can have a clear guiding path and a stable driving source, which is conducive to improving the air supply stability of the air supply channel and enhancing the airflow support of the grass discharge channel, while facilitating structural integration and assembly.

[0065] In some embodiments of this disclosure, based on the foregoing scheme, the air supply channel is disposed within the cutting cavity; Alternatively, the air supply channel may be located outside the cutting cavity.

[0066] In this embodiment, the supplementary air channel is located inside the cutting cavity, so that the supplementary airflow can merge with the cutting airflow earlier inside the cutting cavity and flow together to the grass discharge channel; or, the supplementary air channel is located outside the cutting cavity, so that the supplementary airflow flows along a path independent of the cutting cavity before being introduced into the grass discharge channel or merged with the cutting airflow and discharged.

[0067] By arranging the air supply channel inside or outside the cutting cavity, the arrangement position of the air supply channel can be flexibly selected according to the structural space and airflow organization requirements, thereby realizing the introduction and convergence of supplementary airflow under different overall structure schemes and improving the adaptability of the scheme.

[0068] In some embodiments of this disclosure, based on the foregoing solution, the air filler housing and the cutting housing are integrally formed; Alternatively, the air filler housing and the cutting housing may be separate structures.

[0069] In this embodiment, the air supply housing and the cutting housing are integrally formed, so that the air supply channel is formed simultaneously during the housing forming process; or, the air supply housing and the cutting housing are separate structures, which cooperate with each other to form the air supply channel during assembly.

[0070] By setting the air supply housing and the cutting housing as an integral or separate structure, the air supply channel can be formed under different manufacturing and assembly schemes: integral molding helps to reduce the number of parts and improve the consistency of channel forming, while separate structure helps to improve the flexibility of structural design and assembly adaptability.

[0071] According to a second aspect of the embodiments of this specification, a lawn mowing device is provided, comprising: The housing includes a grass discharge channel having a grass discharge outlet; A cutting device is mounted on the housing and is used to perform cutting operations. When the cutting device performs cutting operations, it generates a cutting airflow, which is discharged through the grass discharge channel. The lawn mowing equipment also includes: An airflow generator is disposed on the housing. The airflow generator is configured to generate supplementary airflow, which merges with the cutting airflow and is discharged through the grass discharge channel. Furthermore, the supplementary airflow and the cutting airflow converge upstream of the grass discharge outlet, or the supplementary airflow and the cutting airflow converge at the grass discharge outlet.

[0072] When the lawn mowing equipment is working, the cutting device performs a cutting operation to generate a cutting airflow. The cutting airflow flows along the grass discharge channel and is discharged through the grass discharge port. At the same time, the airflow generator produces a supplementary airflow, which is introduced into the grass discharge channel along a preset path and merges with the cutting airflow before being discharged together through the grass discharge channel. Specifically, the supplementary airflow and the cutting airflow merge upstream of the grass discharge port, or merge at the grass discharge port before being discharged.

[0073] By limiting the convergence point of the supplementary airflow and the cutting airflow to upstream of or at the discharge outlet, the supplementary airflow can be superimposed on the cutting airflow at or before the end of the discharge channel, thereby enhancing the airflow support near the discharge outlet. This is beneficial to improving the stability of the transport and discharge of grass clippings in the discharge channel, especially under conditions of high discharge resistance, which can reduce the risk of poor discharge and accumulation.

[0074] In some embodiments of this disclosure, based on the foregoing scheme, the airflow generating device and the cutting device are configured to be driven by different driving devices.

During operation, the cutting device performs cutting operations under the drive of its corresponding drive device to generate a cutting airflow; the airflow generating device generates supplementary airflow under the drive of another drive device, and the supplementary airflow and the cutting airflow converge upstream of or at the discharge port and are discharged together.

[0076] By setting the airflow generator and the cutting device to be driven by different drive devices, the generation of supplementary airflow and the operation of the cutting device are independent of each other. This helps to provide stable supplementary airflow support when the cutting load changes and the cutting airflow fluctuates, thereby improving the discharge stability at the end of the grass discharge channel.

[0077] In some embodiments of this disclosure, based on the foregoing scheme, the cutting device is driven by a first motor; the airflow generating device is driven by a second motor.

[0078] In this embodiment, when the mowing equipment is working, the first motor drives the cutting device to perform the cutting operation and generate a cutting airflow. The cutting airflow flows along the grass discharge channel and is discharged through the grass discharge port. The second motor drives the airflow generator to generate supplementary airflow. The supplementary airflow is introduced into the grass discharge channel and merges with the cutting airflow upstream of or at the grass discharge port before being discharged together.

[0079] By driving the cutting device and the airflow generator with the first motor and the second motor respectively, the generation of supplementary airflow is independent of the driving state of the cutting device. It can still provide supplementary airflow when the cutting load increases or the cutting airflow weakens, and superimpose it with the cutting airflow near the grass discharge port, thereby improving the airflow support and grass discharge stability at the end of the grass discharge channel.

[0080] In some embodiments of this disclosure, based on the foregoing scheme, the housing includes a cutting housing and a supplementary air housing connected to the cutting housing; the supplementary air housing and the cutting housing together form a supplementary air channel; The cutting housing has a cutting cavity that is connected to the grass discharge channel; the air supply channel is located inside the cutting cavity; or, the air supply channel is located outside the cutting cavity.

[0081] In this embodiment, the housing includes a cutting housing and a supplementary air housing connected to the cutting housing. The supplementary air housing and the cutting housing cooperate to form a supplementary air channel. The cutting housing has a cutting cavity that communicates with the grass discharge channel. The supplementary air channel is located inside the cutting cavity, allowing the supplementary airflow to merge with the cutting airflow inside the cutting cavity and then enter the grass discharge channel for discharge. Alternatively, the supplementary air channel is located outside the cutting cavity, allowing the supplementary airflow to flow along a path outside the cutting cavity and then be introduced into the grass discharge channel or merge with the cutting airflow and be discharged.

[0082] By forming a supplementary air channel together with the supplementary air housing and the cutting housing, a stable supplementary airflow introduction path can be constructed in the housing structure, which facilitates structural integration and assembly. At the same time, the supplementary air channel can be arranged inside or outside the cutting cavity, making the introduction and convergence position of the supplementary airflow optional, thereby improving the adaptability of the solution to different overall structure and airflow organization requirements.

[0083] In some embodiments of this disclosure, based on the foregoing scheme, the supplementary airflow includes a first airflow and a second airflow; The housing is equipped with a makeup air inlet; The airflow generating device includes: The air supply fan blades are configured to be driven to rotate by the second motor; The first channel is configured to guide the first airflow through it, and the first channel connects the make-up air inlet and the air inlet side of the make-up air fan blade; The second channel is configured to guide the second airflow through it.

[0084] In this embodiment, the supplementary airflow generated by the airflow generator includes a first airflow and a second airflow, and the housing is equipped with a supplementary air inlet. During operation, the second motor drives the supplementary air fan blades to rotate, causing air to flow under the suction of the supplementary air fan blades; the first airflow flows under the guidance of the first channel, which connects the supplementary air inlet and the air intake side of the supplementary air fan blades, allowing the first airflow to enter through the supplementary air inlet and flow to the air intake side of the supplementary air fan blades; the second airflow flows under the guidance of the second channel and enters the air intake side of the supplementary air fan blades along the second channel or merges with the first airflow before entering the air intake side of the supplementary air fan blades. Subsequently, the first and second airflows are pushed by the supplementary air fan blades and discharged through the grass discharge channel.

[0085] By dividing the supplementary airflow into a first airflow and a second airflow, and setting up a first channel and a second channel respectively to guide the two airflows, the two airflows can flow stably along a preset path and converge to form a more stable supplementary airflow supply under the action of the supplementary airflow fan blades, which helps to enhance the airflow support and the stability of the weed discharge channel.

[0086] In some embodiments of this disclosure, based on the foregoing scheme, the supplementary airflow includes a first airflow and a second airflow; The first airflow and the second airflow converge on the air inlet side of the make-up air fan blade; or the first airflow and the second airflow converge upstream on the air inlet side of the make-up air fan blade.

During operation, the first airflow and the second airflow flow along their respective airflow paths and converge on the air intake side of the supplementary airflow fan blade; or, the first airflow and the second airflow converge upstream of the air intake side of the supplementary airflow fan blade and then flow together toward the air intake side of the supplementary airflow fan blade, so that they are drawn in by the supplementary airflow fan blade and further guided into the grass discharge channel for discharge.

[0088] By setting the confluence of the first and second airflows on the air inlet side or upstream of the supplementary air fan blade, the two airflows can be combined before entering the supplementary air fan blade, which helps to improve the collection efficiency and air supply stability of the supplementary airflow, thereby providing more stable airflow support for the grass discharge channel.

[0089] According to a third aspect of the embodiments of this specification, a lawn mowing device is provided, comprising: The casing includes the grass-draining channel; A cutting device is mounted on the housing and is used to perform cutting operations. When the cutting device performs cutting operations, it generates a cutting airflow, which is discharged through the grass discharge channel. Also includes: An airflow generator is disposed on the housing. The airflow generator is configured to generate supplementary airflow, which merges with the cutting airflow and is discharged through the grass discharge channel. as well as The battery pack is installed inside the housing; A control device, installed within the housing, is configured to control the operation of the lawnmower; wherein the supplemental airflow includes a first airflow and a second airflow, the first airflow flowing through at least one of the battery pack and the control device, and the second airflow flowing through at least the other of the battery pack and the control device.

[0090] In this embodiment, when the lawn mower is operating, the cutting device performs a cutting operation to generate a cutting airflow, which flows along the grass discharge channel and is discharged. Simultaneously, the airflow generator produces a supplementary airflow, which is introduced into the grass discharge channel and merges with the cutting airflow before being discharged together through the grass discharge channel. The lawn mower also includes a battery pack and a control device installed within the housing. The supplementary airflow includes a first airflow and a second airflow, wherein the first airflow flows along a first airflow path and passes through at least one of the battery pack and the control device, and the second airflow flows along a second airflow path and passes through at least the other of the battery pack and the control device. Subsequently, the first airflow and the second airflow are introduced into the grass discharge channel and merge with the cutting airflow before being discharged.

[0091] By dividing the supplementary airflow into a first airflow and a second airflow, and allowing the two airflows to flow through the battery pack and control device respectively, the supplementary airflow can be used to divert and exchange heat for different heat-generating components, which helps to reduce the temperature rise of the battery pack and control device and improve the stability of equipment operation. At the same time, the supplementary airflow and the cutting airflow converge and are discharged together through the grass discharge channel, which can provide airflow support for the grass discharge channel while achieving heat dissipation, thereby enhancing the grass clipping conveying and discharge effect.

[0092] In some embodiments of this disclosure, based on the foregoing scheme, the battery pack includes a battery casing and battery cells disposed within the battery casing; The battery casing has a heat dissipation vent, and the casing has a make-up air inlet corresponding to the heat dissipation vent; The makeup air inlet is located on the flow path of either the first airflow or the second airflow.

[0093] In this embodiment, the battery pack includes a battery casing and battery cells disposed within the battery casing. The battery casing has heat dissipation vents; the casing also has an air intake corresponding to the heat dissipation vents. During operation, the air intake is located in the flow path of either the first airflow or the second airflow, allowing air to enter through the air intake and flow into the battery casing through the heat dissipation vents. After flowing through the battery cells, the air is discharged and continues to flow along the corresponding airflow path, eventually being guided into the grass discharge channel and converging with the cutting airflow before being discharged.

[0094] By setting heat dissipation vents on the battery casing and setting corresponding air intake vents on the casing, and placing the air intake vents on the path of the first or second airflow, a stable air intake path can be provided for the battery pack and the heat exchange and heat dissipation capacity of the battery cells can be enhanced. At the same time, the airflow flowing through the battery pack continues to be used for the grass discharge channel, realizing the synergistic reuse of heat dissipation airflow and air intake airflow.

[0095] In some embodiments of this disclosure, based on the foregoing scheme, the airflow generating device and the cutting device are configured to be driven by different driving devices.

[0096] In this embodiment, the airflow generating device and the cutting device are driven by different drive devices. During operation, the cutting device performs cutting operations under the drive of its corresponding drive device to generate a cutting airflow; the airflow generating device generates supplementary airflow under the drive of another drive device, and the supplementary airflow and the cutting airflow merge and are discharged together through the grass discharge channel.

[0097] By setting the airflow generator and the cutting device to be driven by different drive devices, the generation of supplementary airflow and the operation of the cutting device are independent of each other. This helps to provide stable supplementary airflow support when the cutting load changes and the cutting airflow fluctuates, thereby improving the discharge stability of the grass discharge channel.

[0098] In some embodiments of this disclosure, based on the foregoing scheme, the cutting device is driven by a first motor; the airflow generating device is driven by a second motor.

[0099] In this embodiment, when the mowing equipment is working, the first motor drives the cutting device to perform the cutting operation and generate a cutting airflow, which is discharged through the grass discharge channel; the second motor drives the airflow generator to generate a supplementary airflow, which is introduced into the grass discharge channel and merges with the cutting airflow before being discharged together.

[0100] By driving the cutting device and the airflow generator with the first motor and the second motor respectively, the generation of supplementary airflow is independent of the driving state of the cutting device. Supplementary airflow can still be provided when the cutting load increases or the cutting airflow weakens, which helps to improve the stability of the grass discharge channel.

[0101] In some embodiments of this disclosure, based on the foregoing scheme, the airflow generating device includes: The air supply fan blades are configured to be driven to rotate by the second motor; The first channel is configured to guide the first airflow through it, and the first channel connects the make-up air inlet and the air inlet side of the make-up air fan blade; The second channel is configured to guide the second airflow through it.

[0102] In this embodiment, the airflow generating device includes a supplementary air fan blade, a first channel, and a second channel. During operation, a second motor drives the supplementary air fan blade to rotate; a first airflow flows under the guidance of the first channel, which connects the supplementary air inlet to the air inlet side of the supplementary air fan blade, allowing the first airflow to enter through the supplementary air inlet and flow to the air inlet side of the supplementary air fan blade; a second airflow flows under the guidance of the second channel and is introduced into the air inlet side of the supplementary air fan blade, and then the first and second airflows are drawn in by the supplementary air fan blade and further introduced into the weed discharge channel for discharge.

[0103] By setting up a supplementary air fan driven by a second motor, and setting up a first channel and a second channel to guide the first airflow and the second airflow respectively, the two airflows can be stably converged along a preset path to the air inlet side of the supplementary air fan, which helps to improve the supply stability and path controllability of the supplementary airflow, thereby enhancing the airflow support of the grass discharge channel.

[0104] In some embodiments of this disclosure, based on the aforementioned scheme, the first airflow and the second airflow converge on the air inlet side of the make-up air fan blade; or, the first airflow and the second airflow converge upstream of the air inlet side of the make-up air fan blade.

[0105] In this embodiment, the first airflow and the second airflow flow along their respective airflow paths and converge on the air intake side of the supplementary airflow vane; or, the first airflow and the second airflow converge upstream of the air intake side of the supplementary airflow vane and then flow together toward the air intake side of the supplementary airflow vane, so that they are drawn in by the supplementary airflow vane and further guided into the grass discharge channel for discharge.

[0106] By setting the confluence of the first and second airflows on the air inlet side or upstream of the supplementary air fan blade, the two airflows can be combined before entering the supplementary air fan blade, which helps to improve the collection efficiency and air supply stability of the supplementary airflow, thereby providing more stable airflow support for the grass discharge channel.

[0107] The technical solutions provided in the embodiments of this specification may include the following beneficial effects: In the embodiments described in this specification, when the mowing equipment is working, the cutting device performs cutting operations and generates a cutting airflow under the drive of its driving device. The cutting airflow flows along the grass discharge channel and is discharged. Simultaneously, the airflow generator operates under the drive of a different driving device to generate supplementary airflow. The supplementary airflow also flows along the grass discharge channel and is discharged, thus ensuring that both cutting airflow and supplementary airflow exist in the grass discharge channel and participate in the discharge process together. Compared to related technologies that typically rely solely on the airflow generated by the cutting device for grass discharge, this solution, by setting up an airflow generator driven by an independent driving device, makes the generation of supplementary airflow independent of the load state of the cutting device. This allows for additional airflow support when the cutting airflow is insufficient, thereby improving the airflow supply capacity and discharge stability in the grass discharge channel and reducing the probability of problems such as shortened grass discharge distance, blockage, or reduced grass collection basket fullness.

[0108] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this specification. Attached Figure Description

[0119] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this specification. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this specification as detailed in the appended claims.

[0120] The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of this specification. The singular forms “a,” “the,” and “the” as used in this specification and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any and all possible combinations of one or more of the associated listed items.

[0121] It should be understood that although the terms first, second, third, etc., may be used in this specification to describe various information, this information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this specification, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to determination."

[0122] In related technologies, lawn mowing equipment typically relies solely on the airflow generated by the rotation of the cutting device to transport and discharge grass clippings along the discharge channel. However, under conditions such as cutting heavy loads or wet grass, the increased amount or weight of grass clippings in the air duct significantly increases the flow resistance, leading to airflow attenuation and a decrease in grass clipping transport speed. This can easily result in shortened discharge distances, poor discharge, or even accumulation and blockage, reducing the fullness of the grass collection basket and requiring frequent cleaning, thus affecting operational efficiency and user experience. Existing solutions that supplement air through the air duct often have limited supplementary air volume and do not provide significant improvement, making it difficult to effectively solve the above problems.

[0123] Based on this, this application provides a lawn mowing device, as shown below. Figures 1 to 8 A detailed description of the structure of lawn mowing equipment is provided below: The technical solution provided in Embodiment 1 of the present invention is as follows: The lawn mowing equipment includes a housing 1, a cutting device 2, and an airflow generator 3. The housing 1 includes a grass discharge channel 11; the cutting device 2 is mounted on the housing 1 and is used to perform cutting operations. When the cutting device 2 performs cutting operations, it generates a cutting airflow, which is discharged through the grass discharge channel 11; the lawn mowing equipment also includes an airflow generator 3, which is mounted on the housing 1 and is configured to generate supplementary airflow, which is discharged through the grass discharge channel 11; wherein, the airflow generator 3 and the cutting device 2 are configured to be driven by different drive devices.

[0124] When the mowing equipment is working, the cutting device 2 operates under the drive of its drive unit to perform cutting operations and generate cutting airflow, which is discharged along the grass discharge channel 11. At the same time, the airflow generator 3 operates under a different drive unit than the cutting device 2 to generate supplementary airflow. The supplementary airflow is introduced into the grass discharge channel 11 and merges and superimposes with the cutting airflow within the grass discharge channel 11 before being discharged together. By having the airflow generator 3 and the cutting device 2 driven by different drive units, the generation of supplementary airflow is independent of the load state of the cutting device 2. This provides additional airflow support when the cutting airflow is insufficient or the grass discharge resistance increases, thereby enhancing the airflow supply capacity within the grass discharge channel 11, improving the stability of grass clipping conveying and discharge, and reducing the risk of poor grass discharge and accumulation blockage.

[0125] It is understood that the cutting device 2 may use the blade assembly and its drive structure commonly used in existing lawn mowing equipment. Its specific structure and working principle are well known to those skilled in the art and will not be described in detail here.

[0126] When the mowing equipment is working, the first motor 21 drives the cutting device 2 to perform the cutting operation and generate a cutting airflow, which is discharged along the grass discharge channel 11. At the same time, the second motor 31 drives the airflow generator 3 to generate supplementary airflow, which is introduced into the grass discharge channel 11 and merges with the cutting airflow before being discharged together. By setting the airflow generator 3 and the cutting device 2 to be driven by different drive devices, the generation of supplementary airflow and the operation of the cutting device 2 are independent of each other. This allows for stable supplementary airflow support even when the cutting load changes, causing fluctuations in the cutting airflow. It also facilitates the separate adjustment of the working states of the cutting operation and the supplementary airflow process, thereby improving the stability of the grass discharge process.

[0127] It should be noted that the first motor 21 driving the cutting device 2 and the second motor 31 driving the airflow generating device 3 are merely examples to illustrate that the cutting device 2 and the airflow generating device 3 are driven by independent driving devices. In other embodiments, the driving devices for the cutting device 2 and the airflow generating device 3 can also be other types of driving sources or driving mechanisms, as long as they can achieve independent driving of the two.

[0128] In some embodiments of this disclosure, the housing 1 is configured with a cutting cavity 121, and the cutting device 2 is disposed within the cutting cavity 121. The cutting cavity 121 is connected to the grass discharge channel 11. In this embodiment, the cutting cavity 121 is used to accommodate the cutting device 2 and define the cutting operation space, so that the grass clippings and airflow generated during the cutting process gather in the cutting cavity 121 and are guided to the grass discharge channel 11. By connecting the cutting cavity 121 with the grass discharge channel 11, grass clippings and airflow can smoothly enter the grass discharge channel 11 from the cutting cavity 121 and be discharged, thereby reducing the possibility of grass clippings remaining and accumulating in the housing 1, and improving the continuity and stability of the grass discharge process.

[0129] In some embodiments of this disclosure, the lawn mowing device further includes a battery pack 4 and a control device 5. The battery pack 4 is installed inside the housing 1 and includes a battery casing 41 and battery cells 42 disposed inside the battery casing 41; the control device 5 is installed inside the housing 1 and is configured to control the operation of the lawn mowing device.

[0130] In this embodiment, the battery pack 4 is used to power the mowing equipment, and the battery cell 42 serves as an energy storage unit to provide power to components such as the cutting device 2 and the airflow generating device 3. The control device 5 is used to control the operation of the mowing equipment, realize the start-up and shutdown of each component, the working status and the operation strategy, thereby ensuring the coordination and stability of the mowing operation and the air replenishment process.

[0131] In some embodiments of this disclosure, supplementary airflow can flow through the battery pack 4. Specifically, the supplementary airflow generated by the airflow generator 3 enters the area where the battery pack 4 is located or enters the internal space of the battery casing 41 during the flow process, flows through the battery cell 42 and then leaves the battery pack 4 and continues to flow, and finally enters the grass discharge channel 11 for discharge.

[0132] In other embodiments of this disclosure, the cutting airflow can flow through the battery pack 4. Specifically, the cutting airflow generated by the operation of the cutting device 2 is guided to the area where the battery pack 4 is located or enters the internal space of the battery casing 41 before being discharged through the grass discharge channel 11, flows through the battery cell 42 and then leaves the battery pack 4 and continues to flow, eventually entering the grass discharge channel 11 for discharge.

[0133] In some other embodiments of this disclosure, both the supplementary airflow and the cutting airflow can flow through the battery pack 4. The supplementary airflow and the cutting airflow enter the area where the battery pack 4 is located or enter the internal space of the battery casing 41 along their respective paths, and leave the battery pack 4 after flowing through the battery cell 42, and then enter the grass discharge channel 11 and are discharged. In this way, the two airflows can merge before entering the battery pack 4, inside the battery pack 4, or after leaving the battery pack 4 to form a mixed airflow after heat exchange by the battery pack 4.

[0134] In some embodiments of this disclosure, supplementary airflow can flow through control device 5. The supplementary airflow generated by airflow generator 3 enters the area where control device 5 is located or enters the space containing control device 5 during the flow process, passes over or through the surface of control device 5, leaves the area of ​​control device 5 and continues to flow, and finally enters the grass discharge channel 11 for discharge.

[0135] In some other embodiments of this disclosure, the cutting airflow can flow through the control device 5. The cutting airflow generated by the operation of the cutting device 2 is guided to the area where the control device 5 is located or into the space containing the control device 5 before being discharged through the grass discharge channel 11, sweeps over or passes through the surface of the control device 5, leaves the area of ​​the control device 5 and continues to flow, and finally enters the grass discharge channel 11 for discharge.

[0136] In other embodiments of this disclosure, both the supplementary airflow and the cutting airflow can flow through the control device 5. The supplementary airflow and the cutting airflow enter the area where the control device 5 is located or enter the space containing the control device 5 along their respective paths, and leave the area of ​​the control device 5 after passing over or through the surface of the control device 5, and then enter the grass discharge channel 11 and are discharged. In this manner, the two airflows can merge before entering the control device 5, near the control device 5, or after leaving the control device 5 to form a mixed airflow after heat exchange by the control device 5.

[0137] In some embodiments of this disclosure, the supplementary airflow may flow only through the battery pack 4. During its flow, the supplementary airflow enters the area where the battery pack 4 is located or enters the internal space of the battery casing 41, flows through the battery cell 42, leaves the battery pack 4 and continues to flow, and finally enters the grass discharge channel 11 for discharge.

[0138] In other embodiments of this disclosure, the supplementary airflow may flow only through the control device 5. During its flow, the supplementary airflow enters the area where the control device 5 is located or enters the space containing the control device 5, passes over or through the surface of the control device 5, leaves the area of ​​the control device 5 and continues to flow, and finally enters the grass discharge channel 11 for discharge.

[0139] In some other embodiments of this disclosure, the supplementary airflow flows through the battery pack 4 and the control device 5 simultaneously: the supplementary airflow flows through the battery pack 4 and the control device 5 sequentially along the same airflow path, or enters the areas where the battery pack 4 and the control device 5 are located respectively and then merges, and then enters the grass discharge channel 11 for discharge; in this manner, the supplementary airflow can exchange heat with the corresponding components respectively during the process of flowing through the battery pack 4 and the control device 5 and then continue to flow.

[0140] In some embodiments of this disclosure, the supplementary airflow includes a first airflow and a second airflow; the first airflow flows through the battery pack 4, and the second airflow flows through the control device 5. During its flow, the first airflow enters the area where the battery pack 4 is located or enters the internal space of the battery casing 41, flows through the battery cell 42, leaves the battery pack 4, and continues to flow; during its flow, the second airflow enters the area where the control device 5 is located or enters the space accommodating the control device 5, passes over or through the surface of the control device 5, leaves the area of ​​the control device 5, and continues to flow; subsequently, the first airflow and the second airflow enter the weed discharge channel 11 and are discharged, and in this manner, the two airflows may merge before entering the weed discharge channel 11 or within the weed discharge channel 11 to form a mixed airflow after heat exchange between the battery pack 4 and the control device 5.

[0141] In other embodiments of this disclosure, the supplementary airflow includes a first airflow and a second airflow; the first airflow flows through the control device 5 and the second airflow flows through the battery pack 4. During its flow, the first airflow enters the area where the control device 5 is located or enters the space accommodating the control device 5, passes over or through the surface of the control device 5, and then leaves the area where the control device 5 is located and continues to flow; during its flow, the second airflow enters the area where the battery pack 4 is located or enters the internal space of the battery casing 41, flows through the battery cell 42, and then leaves the battery pack 4 and continues to flow; subsequently, the first airflow and the second airflow enter the weed discharge channel 11 and are discharged, and in this manner, the two airflows may merge before entering the weed discharge channel 11, within the weed discharge channel 11, or after leaving the weed discharge channel 11.

[0142] In other embodiments of this disclosure, the supplementary airflow includes a first airflow and a second airflow; the first airflow and the second airflow flow through corresponding components in the battery pack 4 and the control device 5 respectively and then merge before entering the grass discharge channel 11. The first airflow and the second airflow enter the area where the battery pack 4 is located and the area where the control device 5 is located along corresponding paths respectively and leave after completing heat exchange; in this mode, the two airflows can merge on the air inlet side of the supplementary air fan blade 32, upstream of the air inlet side of the supplementary air fan blade 32, or upstream of the grass discharge port 111 to form a merged supplementary airflow and enter the grass discharge channel 11 for discharge.

[0143] In other embodiments of this disclosure, the supplementary airflow includes a first airflow and a second airflow; the first airflow and the second airflow flow through corresponding components in the battery pack 4 and the control device 5, respectively, and then converge in the grass discharge channel 11. The first airflow flows through one of the battery pack 4 or the control device 5 and leaves during its flow, while the second airflow flows through the other and leaves during its flow. The two airflows are respectively introduced into the grass discharge channel 11 and flow along the grass discharge channel 11. In this manner, the two airflows converge and are discharged together in the grass discharge channel 11, thereby forming a mixed airflow after heat exchange between the battery pack 4 and the control device 5.

[0144] In other embodiments of this disclosure, the battery casing 41 is provided with a heat dissipation vent 411, and the casing 1 is provided with a supplementary air inlet 13 corresponding to the heat dissipation vent 411; the supplementary air inlet 13 is located on at least one supplementary airflow path. During operation, the supplementary airflow flows along the corresponding airflow path, enters through the supplementary air inlet 13, flows into the battery casing 41 through the heat dissipation vent 411, flows through the battery cell 42, and then exits from the battery pack 4 and continues to flow along the supplementary airflow path, finally entering the grass discharge channel 11 for discharge.

[0145] It is understandable that the battery pack 4 is a detachable structure. When the battery pack 4 is installed on the housing 1, the heat dissipation vent 411 and the air supply inlet 13 are positioned opposite each other and connected in the assembled state, making the air supply inlet 13 the air inlet of the battery pack 4, thereby introducing a flow path of supplementary airflow into the battery pack 4; when the battery pack 4 is removed from the housing 1, the heat dissipation vent 411 and the air supply inlet 13 are no longer connected, and the supplementary airflow no longer enters the battery pack 4 along this path.

[0146] It should be noted that the arrows in the accompanying drawings of this application indicate the direction of airflow.

[0147] In some embodiments of this disclosure, the airflow generating device 3 includes: a makeup air fan blade 32, which is configured to be driven to rotate by a second motor 31; and a first channel 33, which is configured to guide the first airflow through, the first channel 33 connecting the makeup air inlet 13 and the air inlet side of the makeup air fan blade 32.

[0148] In this embodiment, when the lawnmower is working, the second motor 31 drives the supplementary air fan 32 to rotate, forming a first airflow under the suction action of the supplementary air fan 32. The first airflow flows under the guidance of the first channel 33, which connects the supplementary air inlet 13 and the air inlet side of the supplementary air fan 32. This allows air to enter through the supplementary air inlet 13 and flow along the first channel 33 to the air inlet side of the supplementary air fan 32. Subsequently, it is drawn in by the supplementary air fan 32 and continues to be guided into the subsequent airflow path until it is discharged. By driving the supplementary air fan 32 with the second motor 31 and cooperating with the first channel 33 to guide the first airflow, the first airflow can have a clear air inlet and a stable flow path, which helps to reduce airflow short-circuiting and disorderly leakage, thereby improving the formation stability and introduction efficiency of the supplementary airflow.

[0149] In some embodiments of this disclosure, a mounting portion 14 is constructed on the housing 1, and the control device 5 is mounted on the mounting portion 14; and at least a portion of the mounting portion 14 is located on the flow path of the second airflow. During operation, the second airflow flows along the corresponding airflow path, and passes through the mounting portion 14 located on the path during its flow, thereby passing through the control device 5 mounted on the mounting portion 14 and continuing to flow before finally being discharged. By placing at least a portion of the mounting portion 14 on the flow path of the second airflow, the second airflow can directly cover the area where the control device 5 is located, which is beneficial for using the second airflow to exchange and dissipate heat from the control device 5 and improves the temperature stability of the control device 5 during operation.

[0150] Furthermore, the airflow generating device 3 also includes a second channel 34; the second channel 34 is configured to guide the second airflow through it. During operation, the second airflow flows along a preset path under the guidance of the second channel 34, and enters the subsequent airflow path through the second channel 34 until it is discharged. By setting the second channel 34 to guide the second airflow, the second airflow can have a clear flow path, which is beneficial to improving the stability and controllability of the second airflow guidance.

[0151] In some embodiments of this disclosure, the housing 1 includes a cut housing 12 and a mounting housing 15; the cut housing 12 includes a first sub-housing 122, and the mounting housing 15 includes a second sub-housing 151 corresponding to the first sub-housing 122; wherein the first sub-housing 122 and the second sub-housing 151 together enclose a second channel 34. By utilizing the corresponding substructures on the cut housing 12 and the mounting housing 15 to jointly enclose the second channel 34, the second airflow can be guided without adding an additional independent air guide duct, which is beneficial for simplifying the structure, improving space utilization, and enhancing the stability of the second channel 34 formation.

[0152] In this embodiment, after the cutting housing 12 and the mounting housing 15 are assembled, the first sub-housing 122 and the second sub-housing 151 are arranged opposite to each other and cooperate with each other, forming a channel space for the flow of the second airflow, thereby forming the second channel 34. The second airflow enters the channel space during the flow process and is guided to the subsequent airflow path within the path defined by the first sub-housing 122 and the second sub-housing 151 until it is discharged.

[0153] Furthermore, the housing 1 may also include a guide plate 17. A guide groove 152 is constructed on the side of the mounting housing 15 away from the cutting housing 12, and the guide plate 17 is detachably mounted on the side of the mounting housing 15 away from the cutting housing 12, and together with the guide groove 152, forms a first channel 33.

[0154] In some embodiments, the guide plate 17 can be detachably installed on the mounting housing 15 by snap-fit. For example, the guide plate 17 is provided with a buckle, hook, or tongue, and the mounting housing 15 is provided with a corresponding slot, hole, or limiting part to achieve positioning connection after assembly. Alternatively, the guide plate 17 can be detachably installed on the mounting housing 15 by screwing. For example, the guide plate 17 is connected to the mounting housing 15 by fasteners such as screws and bolts. Insertion, hooking, magnetic connection, or other connection methods that are easy to disassemble and assemble can also be used.

[0155] It should be noted that the above-described detachable installation method is merely an example, and this disclosure is not limited thereto. Any other connection method that enables the guide plate 17 to be detachably connected to the mounting housing 15 and to form the first channel 33 together with the guide groove 152 is applicable to this disclosure.

[0156] In some embodiments of this disclosure, the first sub-shell 122 may be a first wall panel 1221 protruding from the surface of the cutting shell 12; the second sub-shell 151 may be a second wall panel 1511 protruding from the surface of the mounting shell 15, wherein the first wall panel 1221 and the second wall panel 1511 enclose each other to form a second channel 34.

[0157] By setting both the first sub-shell 122 and the second sub-shell 151 as wall panel structures protruding from the surface of the cut shell 12, and forming the second channel 34 by the first wall panel 1221 and the second wall panel 1511, the flow path of the second airflow can be directly formed by the cut shell 12 body, reducing the setting of independent air guides, which is conducive to simplifying the structure and improving space utilization. At the same time, the first wall panel 1221 and the second wall panel 1511 can form a clearer boundary for the second channel 34, which is conducive to improving the stability and controllability of the second airflow guidance.

[0158] In some embodiments, the first wall panel 1221 may include two first sub-plates arranged at relative intervals (not specifically labeled in the accompanying drawings), and the second wall panel 1511 may include two second sub-plates arranged opposite to the two first sub-plates (not specifically labeled in the accompanying drawings). When the first sub-shell 122 and the second sub-shell 151 are connected, the two first sub-plates respectively mate with the two second sub-plates, thereby jointly forming the second channel 34. By using multiple sub-plates to form the second channel 34, the limiting effect of the channel boundary can be further improved, which is beneficial to enhancing the forming accuracy and flow guiding stability of the second channel 34.

[0159] In other embodiments, the first sub-shell 122 and the second sub-shell 151 together form the second channel 34, and the first sub-shell 122 and the second sub-shell 151 are integrally formed. During operation, the second airflow enters the second channel 34 and flows within the channel path jointly defined by the first sub-shell 122 and the second sub-shell 151, and is then guided to the subsequent airflow path until it is discharged. By using the first sub-shell 122 and the second sub-shell 151 to jointly form the second channel 34 and employing an integral molding method to construct the channel boundary, assembly gaps and channel deviations can be reduced, which is beneficial to improving the molding consistency, sealing performance, and stability of the second airflow guidance of the second channel 34.

[0160] In some embodiments, the channel structures corresponding to the first sub-shell 122 and the second sub-shell 151 can be formed by integral molding, so that the first sub-shell 122 and the second sub-shell 151 have a predetermined relative positional relationship during molding and jointly define the channel space of the second channel 34. Compared with the method of forming the second channel 34 by separate assembly, the integral molding method is beneficial to reduce the number of parts and assembly steps, and reduce the risk of airflow leakage or channel displacement caused by assembly errors.

[0161] In some embodiments of this disclosure, the housing 1 includes a cutting housing 12 and a mounting housing 15. The cutting housing 12 includes a first sub-housing 122, which is configured to form a second channel 34 with the mounting housing 15 when the cutting housing 12 and the mounting housing 15 are assembled. During operation, a second airflow enters the second channel 34 and flows within the channel path jointly defined by the first sub-housing 122 and the mounting housing 15, and is then guided to a subsequent airflow path until it is discharged. By utilizing the first sub-housing 122 to form the second channel 34 with the mounting housing 15 in the assembled state, the second airflow can be guided without adding an additional independent air guide, which simplifies the structure and improves space utilization, while also improving the stability and controllability of the second airflow path.

[0162] In this embodiment, after the cutting housing 12 and the mounting housing 15 are assembled, the corresponding surfaces of the first sub-housing 122 and the mounting housing 15 cooperate with each other, forming a channel space between them for the flow of the second airflow, thereby forming the second channel 34. By adopting the method of forming the second channel 34 after assembly, the second channel 34 can be integrated with the overall assembly structure, which is beneficial to improving the flexibility of structural layout and making it easy to adjust the shape and path of the second channel 34 according to different housing 1 structures.

[0163] In some embodiments of this disclosure, the first sub-housing 122 is a wall panel protruding from the surface of the cutting housing 12, and the wall panel is snapped onto or abutted against the surface of the mounting housing 15 near the cutting housing 12. By setting the first sub-housing 122 as a wall panel protruding from the surface of the cutting housing 12, and making the wall panel snapped onto or abutted against the surface of the mounting housing 15 near the cutting housing 12, a stable channel boundary can be formed after the cutting housing 12 and the mounting housing 15 are assembled. This is beneficial to improving the forming reliability and sealing of the second channel 34, reducing airflow leakage, and improving the stability of the second airflow guidance.

[0164] In some embodiments, the wall panel can be snapped into the corresponding snap-fit ​​part of the mounting housing 15 via a snap-fit ​​structure. For example, the wall panel is provided with a snap hook, snap tongue, or snap protrusion, and the mounting housing 15 is provided with a corresponding snap groove, snap hole, or limiting recess to achieve positioning connection after assembly. Alternatively, the wall panel can be abutted against the surface of the mounting housing 15 near the cutting housing 12. For example, the end, side, or flange of the wall panel abuts against the inner surface, side surface, or step surface of the mounting housing 15, thereby forming a second channel 34 together with the mounting housing 15.

[0165] It should be noted that the above-described snap-fit ​​and abutment methods are merely examples, and this disclosure is not limited to the specific implementations described above. In other embodiments, as long as the wall panel and the mounting housing 15 can form a relatively stable mating relationship and jointly define the boundary of the second channel 34, other suitable snap-fit, abutment, or similar connection and mating methods can be adopted.

[0166] In some embodiments of this disclosure, the first airflow and the second airflow converge on the inlet side of the supplementary air fan blade 32; or, the first airflow and the second airflow converge upstream of the inlet side of the supplementary air fan blade 32. During operation, the first airflow and the second airflow flow along their respective airflow paths and converge directly on the inlet side of the supplementary air fan blade 32 before being drawn in; or, the first airflow and the second airflow first converge upstream of the inlet side of the supplementary air fan blade 32, then flow together towards the inlet side of the supplementary air fan blade 32 and are drawn in, subsequently forming a supplementary airflow that enters the subsequent airflow path until it is discharged. By setting the convergence point of the first airflow and the second airflow on the inlet side of the supplementary air fan blade 32 or upstream of it, the two airflows can be merged before entering the supplementary air fan blade 32, which is beneficial for improving the collection efficiency and air supply stability of the supplementary airflow; at the same time, the convergence point is selectable, facilitating flexible arrangement according to the overall structural space and guide path, thereby improving the adaptability of the solution.

[0167] In some embodiments of this disclosure, the housing 1 includes a cutting housing 12 and a supplementary air housing 16 connected to the cutting housing 12; the cutting housing 12 is provided with an air inlet 123, a grass discharge channel 11 and a cutting cavity 121; the supplementary air housing 16 and the cutting housing 12 together form a supplementary air channel 161; the second motor 31 and the supplementary air fan blade 32 are disposed in the supplementary air channel 161.

[0168] During operation, the first motor 21 drives the cutting device 2 to run within the cutting cavity 121 to perform cutting operations and generate a cutting airflow, which is discharged along the straw discharge channel 11. Simultaneously, the second motor 31 drives the supplementary air fan 32 to rotate within the supplementary air channel 161, allowing outside air to enter through the air inlet 123 and flow along the supplementary air channel 161 to form a supplementary airflow. This supplementary airflow is then guided into the straw discharge channel 11 and merges with the cutting airflow before being discharged together. By arranging the second motor 31 and the supplementary air fan 32 within the supplementary air channel 161 formed by the cutting housing 12 and the supplementary air sub-housing 16, the supplementary airflow can have a clear and relatively stable flow path, which is beneficial for improving the controllability and stability of the air supply process and enhancing the airflow support capacity of the straw discharge channel 11.

[0169] It is understood that the supplementary air channel 161 refers to a channel structure used to guide the flow of supplementary airflow. The supplementary air channel 161 can be formed by the cutting housing 12 and the supplementary air sub-housing 16, so that air flows along a preset path under the action of the supplementary air fan blades 32 driven by the second motor 31 and is introduced into the grass discharge channel 11; in other words, the supplementary air channel 161 is used to provide a guiding path for the supplementary airflow and guide the supplementary airflow to the position where it merges with the cutting airflow.

[0170] In some embodiments of this disclosure, the supplementary air channel 161 can be located inside the cutting cavity 121, allowing the supplementary airflow to merge with the cutting airflow earlier within the cutting cavity 121 before entering the discharge channel 11 for discharge; alternatively, the supplementary air channel 161 can be located outside the cutting cavity 121, allowing the supplementary airflow to flow along a path independent of the cutting cavity 121 before being introduced into the discharge channel 11, and then merge with the cutting airflow within or near the discharge channel 11 before being discharged. By arranging the supplementary air channel 161 inside or outside the cutting cavity 121, the arrangement of the supplementary air channel 161 can be flexibly selected according to the overall machine space layout, the length of the guide path, and the requirements of the confluence position, thereby improving the adaptability of the solution to different structural forms.

[0171] In some embodiments of this disclosure, the air supply sub-shell 16 can be integrally formed with the cutting shell 12, so that the air supply channel 161 is formed synchronously during the forming process of the shell 1; or, the air supply sub-shell 16 and the cutting shell 12 can be separate structures, which cooperate with each other to form the air supply channel 161 during assembly. When using an integral forming method, it is beneficial to reduce the number of parts and improve the forming consistency and sealing of the air supply channel 161; when using a separate structure, it is beneficial to improve the flexibility of structural design and assembly adaptability, and facilitate the adjustment of the shape, position and flow path of the air supply channel 161 according to different product schemes.

[0172] The technical solution provided in Embodiment 2 of the present invention is as follows: In some embodiments of this disclosure, the lawn mowing equipment includes a housing 1, a cutting device 2, and an airflow generator 3. The housing 1 includes a grass discharge channel 11 with a grass discharge outlet 111. The cutting device 2 is mounted on the housing 1 and performs cutting operations. When performing cutting operations, the cutting device 2 generates a cutting airflow, which is discharged through the grass discharge channel 11. The airflow generator 3 is mounted on the housing 1 and is configured to generate supplementary airflow. The supplementary airflow merges with the cutting airflow and is discharged through the grass discharge channel 11. The supplementary airflow and the cutting airflow can merge upstream of the grass discharge outlet 111 or at the grass discharge outlet 111. During operation, the cutting device 2 cuts grass clippings and generates a cutting airflow. The airflow generator 3 generates supplementary airflow synchronously or asynchronously. The supplementary airflow is introduced into the grass discharge channel 11 along a preset airflow path and merges with the cutting airflow near the grass discharge outlet 111 before being discharged together.

[0173] By limiting the convergence point of the supplementary airflow and the cutting airflow to upstream of or at the discharge port 111, the supplementary airflow can directly reinforce the cutting airflow in the end region of the discharge channel 11, thereby enhancing the airflow support capacity near the discharge port 111 and improving the stability of grass clipping transport and discharge within the discharge channel 11. Compared to schemes that rely solely on the cutting device 2 to generate airflow for grass discharge, this embodiment can supplement additional airflow at key discharge locations in the discharge channel 11, thus reducing the risks of poor grass discharge, shortened discharge distance, and grass clipping accumulation under heavy loads or wet grass conditions.

[0174] In some embodiments of this disclosure, the airflow generating device 3 and the cutting device 2 can be driven by different driving devices; for example, the cutting device 2 is driven by a first motor 21, and the airflow generating device 3 is driven by a second motor 31. During operation, the first motor 21 drives the cutting device 2 to form a cutting airflow, and the second motor 31 drives the airflow generating device 3 to form a supplementary airflow. The two flow together upstream of or at the discharge port 111 and are discharged together.

[0175] By having the airflow generator 3 and the cutting device 2 driven by different drive devices, the generation of supplementary airflow can be relatively independent of the load changes of the cutting device 2, thereby providing stable supplementary air support even when the cutting airflow fluctuates, which is beneficial to improving the stability of the grass removal process. The first motor 21 and the second motor 31 are only examples to illustrate that the cutting device 2 and the airflow generator 3 are driven by independent drive sources; in other embodiments, other drive structures capable of driving both separately can also be used.

[0176] In some embodiments of this disclosure, the housing 1 includes a cutting housing 12 and an air supply sub-housing 16 connected to the cutting housing 12. The air supply sub-housing 16 and the cutting housing 12 together form an air supply channel 161. The cutting housing 12 is configured with a cutting cavity 121, which communicates with the grass discharge channel 11. The air supply channel 161 can be located inside or outside the cutting cavity 121. During operation, the supplementary airflow generated by the airflow generator 3 flows along the air supply channel 161 and merges with the cutting airflow at the outlet of the air supply channel 161 or after being introduced into the grass discharge channel 11 through the air supply channel 161. By forming a supplementary air channel 161 together with the cutting housing 12 and the supplementary air sub-housing 16, a clear flow path can be provided for the supplementary airflow, which facilitates structural integration and assembly. At the same time, the arrangement of the supplementary air channel 161 inside or outside the cutting cavity 121 is optional, so it can be flexibly designed according to the overall space, the length of the flow path and the requirements of the confluence position, thereby improving the adaptability of the solution to different product structures.

[0177] In some embodiments of this disclosure, the supplementary airflow includes a first airflow and a second airflow, and a supplementary air inlet 13 is constructed on the housing 1. The airflow generating device 3 includes a supplementary air vane 32, a first channel 33, and a second channel 34. The supplementary air vane 32 is configured to be driven to rotate by a second motor 31; the first channel 33 is configured to guide the first airflow through and connects the supplementary air inlet 13 and the air inlet side of the supplementary air vane 32; the second channel 34 is configured to guide the second airflow through. During operation, the first airflow enters through the supplementary air inlet 13 and flows to the air inlet side of the supplementary air vane 32 under the guidance of the first channel 33; the second airflow flows under the guidance of the second channel 34 and is directed to the air inlet side of the supplementary air vane 32. The first airflow and the second airflow can converge on the air inlet side of the supplementary air vane 32; or, the first airflow and the second airflow can also converge upstream of the air inlet side of the supplementary air vane 32 and flow together to the air inlet side of the supplementary air vane 32, and then be drawn in by the supplementary air vane 32 and further introduced into the grass discharge channel 11.

[0178] By dividing the supplementary airflow into a first airflow and a second airflow, and setting a first channel 33 and a second channel 34 respectively to guide the two airflows, airflows from different sources or with different functions can flow stably along a preset path and merge before entering the supplementary air fan blade 32, thereby improving the collection efficiency and air supply stability of the supplementary airflow. Furthermore, the first airflow and the second airflow merge on the air inlet side of the supplementary air fan blade 32 or upstream, which is conducive to the integration of the two airflows before they are drawn into the supplementary air fan blade 32, making the supplementary airflow output by the supplementary air fan blade 32 more stable, and thus enhancing the airflow support capacity of the end area of ​​the grass discharge channel 11.

[0179] It is understood that the supplementary airflow channel 161 is used to guide the flow of supplementary airflow, the first channel 33 mainly serves as the guide for the first airflow, and the second channel 34 mainly serves as the guide for the second airflow. The supplementary air inlet 13 is used to provide an air inlet for at least one supplementary airflow path, and the supplementary air fan blades 32 are used to draw in and propel the airflow introduced through the first channel 33 and / or the second channel 34. The specific shape, length, and relative position of the above-mentioned channels, inlets, and confluence points can be adjusted according to different product structures. As long as the supplementary airflow and the cutting airflow can converge upstream of or at the grass discharge outlet 111, they should all fall within the protection scope of this disclosure.

[0180] The technical solution provided in Embodiment 3 of the present invention is as follows: The lawn mowing equipment includes a housing 1, a cutting device 2, an airflow generator 3, a battery pack 4, and a control device 5. The housing 1 includes a grass discharge channel 11. The cutting device 2 is mounted on the housing 1 and performs cutting operations, generating a cutting airflow that is discharged through the grass discharge channel 11. The airflow generator 3 is mounted on the housing 1 and is configured to generate supplementary airflow, which merges with the cutting airflow and is discharged through the grass discharge channel 11. The battery pack 4 is installed inside the housing 1, and the control device 5 is also installed inside the housing 1. The control device 5 is configured to control the operation of the lawn mowing equipment. The supplementary airflow includes a first airflow and a second airflow. The first airflow flows through at least one of the battery pack 4 and the control device 5, and the second airflow flows through at least the other of the battery pack 4 and the control device 5, so that the two supplementary airflows simultaneously provide heat exchange and dissipation for different heat-generating components while simultaneously providing supplementary airflow.

[0181] In some embodiments of this disclosure, the battery pack 4 includes a battery casing 41 and battery cells 42 disposed within the battery casing 41. The battery casing 41 has a heat dissipation vent 411, and the casing 1 has a makeup air inlet 13 corresponding to the heat dissipation vent 411, with the makeup air inlet 13 located on the flow path of the first airflow or the second airflow. The airflow generating device 3 and the cutting device 2 can be driven by different driving devices; for example, the cutting device 2 is driven by a first motor 21, and the airflow generating device 3 is driven by a second motor 31. The airflow generating device 3 may include a makeup air fan blade 32, a first channel 33, and a second channel 34. The makeup air fan blade 32 is configured to rotate under the drive of the second motor 31; the first channel 33 is configured to guide the first airflow through, and the first channel 33 connects the makeup air inlet 13 and the air inlet side of the makeup air fan blade 32; the second channel 34 is configured to guide the second airflow through. During operation, the first airflow enters through the supplementary air inlet 13 and flows to the air intake side of the supplementary air fan blade 32 under the guidance of the first channel 33; the second airflow flows under the guidance of the second channel 34 and is directed to the air intake side of the supplementary air fan blade 32; the first airflow and the second airflow can converge on the air intake side of the supplementary air fan blade 32, or converge upstream of the air intake side of the supplementary air fan blade 32 and then flow together to the air intake side of the supplementary air fan blade 32, and are then drawn in by the supplementary air fan blade 32 and further introduced into the grass discharge channel 11, where they converge with the cutting airflow and are discharged together.

[0182] By introducing a first airflow and a second airflow, respectively flowing through the battery pack 4 and the control device 5, into the same device, the air supply capacity of the grass discharge channel 11 can be improved while simultaneously diverting heat to different heat-generating components. This helps reduce the temperature rise of the battery pack 4 and the control device 5 and improves the overall operational stability. Furthermore, by limiting the convergence point of the first and second airflows to the air inlet side of the air supply fan 32 or its upstream, the two airflows can be combined before entering the air supply fan 32, which helps improve the collection efficiency and air supply stability of the supplementary airflow. At the same time, the airflow generating device 3 and the cutting device 2 are driven by different drive devices, so that the generation of the supplementary airflow does not depend on the strength of the cutting airflow. This allows the grass discharge channel 11 to still provide stable airflow support under heavy loads or wet grass conditions, which helps enhance the grass clipping conveying and discharge effect.
