Description

TECHNICAL FIELD

[0001] The utility model relates to the lawn mower technical field, concretely relates to a lawn mower with waterproof function. BACKGROUND

[0002] The lawn mower is a mechanical device specially designed for trimming lawns and vegetation, which rotates at high speed through the built-in engine or electrically driven blade, uses the cutting force generated to cut off weeds, and is widely used in garden greening, parks, streets, residential areas, farmland and sports fields to maintain the neatness and beauty of lawns, improve work efficiency, and ensure the safe use of operators.

[0003] The current handheld lawn mower design mainly focuses on land working environment, especially flat and hard ground such as lawns, fields or courts. However, when some weeds on the water surface need to be cleaned, these handheld lawn mowers often cannot meet the needs. First, when the handheld lawn mower works on the water surface, water can easily penetrate into the protective shell through the blade, which may cause damage to the motor and other key components due to moisture. Since the motor of the lawn mower usually does not have waterproof function, once water enters, it may cause serious consequences such as circuit short circuit and motor burnout. Secondly, the water surface environment lacks support, so the operator needs to maintain balance and stably control the lawn mower when working on the water surface, so the operator is prone to danger when working on the water surface. SUMMARY

[0009] A second waterproof component, the second waterproof component is partially located above the protective shell, and the second waterproof component is used to block water from entering the interior of the protective shell.

[0010] The warning component is located below the protective shell and is used to remind the worker of the working state of the lawn mower.

[0011] The handheld lawn mower (the handheld lawn mower is a mature technology in the prior art, and thus will not be described in detail) is usually composed of a handle, a grip, a battery pack, a motor, a blade, a protective shell and a controller, when it is needed to be used, the motor is controlled to rotate by the controller, at this time, the motor drives the blade fixedly connected with the output end of the motor to rotate, so as to realize the purpose of mowing, when it is needed to clean the weeds on the water surface, the first waterproof component and the second waterproof component are assembled, so that the handheld lawn mower has the waterproof function and can provide certain supporting force for the lawn mower when working on the water surface, so that the worker can clean the weeds on the water surface more easily, thereby avoiding the dangerous situation that the operator cannot balance and stably control the lawn mower, and simultaneously solving the problem that the water beads easily enter the interior of the protective shell and damage the motor.

[0012] Further improvement of the technical scheme of the utility model lies in that: the first waterproof component includes a bottom plate and a fixed plate, a plurality of fixed blocks are arranged uniformly on one side of the bottom plate along the circumferential direction, a fixed groove is formed on the fixed block, an air bag is arranged on the other side of the bottom plate, the fixed block is slidably connected with the protective shell through a second clamping groove, the fixed plate is slidably connected with the protective shell through a rotating groove, a top block is arranged below the fixed plate and is arranged uniformly along the circumferential direction, the top block is slidably connected with the fixed block through a first clamping groove and the fixed groove, and the fixed plate is fixedly connected with the protective shell through a bolt.

[0013] By adopting the above technical scheme, when it is needed to be assembled, the fixed blocks on one side of the bottom plate are aligned with the second clamping grooves, then the fixed blocks are inserted, at this time, the fixed blocks fill the interiors of the second clamping grooves and the clamping blocks, then the fixed plate is slid along the circumferential direction, at this time, the top blocks below the fixed plate are fixed in the clamping blocks through the first clamping grooves and the fixed grooves, then the fixed plate is fixed with the protective shell through the bolt, so that the bottom plate is fixed below the blade through the fixed blocks, the air bag is arranged on the side of the bottom plate away from the fixed blocks, so that the bottom plate has greater buoyancy when on the water surface, thereby the lawn mower is lifted up, and the water in the protective shell is prevented from damaging the motor.

[0014] Further improvement of the technical scheme of the utility model lies in that: the second waterproof component includes a waterproof shell, a through groove is formed on the waterproof shell, and the waterproof shell is fixedly connected with the protective shell through a bolt.

[0015] Using the above technical solution, although the lawnmower can float on the water surface due to its large buoyancy, water droplets can sometimes splash into the protective shell when the lawnmower is working. This can cause water to flow into the protective shell and damage the motor. By setting up a waterproof shell and fixing it to the protective shell with bolts, most of the blades are located inside the waterproof shell, with only some blades exposed. At the same time, the waterproof shell can prevent water droplets from splashing into the protective shell to the greatest extent, thereby protecting the motor.

[0016] A further improvement of this utility model's technical solution is that: the second waterproof component also includes a first gear and a second gear, the first gear meshing with the second gear and the first gear being fixedly connected to the output end of the motor, a shaft being rotatably connected to the protective shell, the second gear being fixedly connected to the shaft, a cam being fixedly connected to the shaft, a cylinder being fixedly connected to the protective shell, a piston plate being slidably connected to the cylinder, a piston rod being fixedly connected to one side of the piston plate, a pressure plate being fixedly connected to the end of the piston rod away from the piston plate, the piston rod being slidably connected to the cylinder, a pressure spring being fixedly connected to the side of the piston plate near the piston rod, the other end of the pressure spring being fixedly connected to the cylinder, an air inlet and an air outlet being provided on the cylinder, a one-way valve being provided at both the air inlet and the air outlet, and several inclined blocks being fixedly connected to the waterproof shell, with nozzles provided on the inclined blocks.

[0017] Using the above technical solution, however, water droplets may adhere to the blade's surface during operation and enter the protective shell through the blade, potentially damaging the motor. When the motor drives the blade, which is fixedly connected to its output end, to rotate, it also drives the first gear, which is fixedly connected to its output end, to rotate. Because the first gear meshes with the second gear, the rotation of the first gear transmits power to the shaft through the second gear, causing the cam, which is fixedly connected to the shaft, to rotate. The rotation of the cam compresses the pressure plate, which in turn moves the piston plate via the piston rod. The pressure spring is in a stretched state, and the movement of the piston plate at this time compresses the air inside the cylinder. Air is introduced through a one-way valve and an air outlet into a nozzle fixedly connected to the inclined block. The air is then sprayed out through the nozzle, dispersing the water droplets on the blades near the through groove, thus preventing water from flowing into the protective shell. When the cam disengages from the pressure plate, the piston plate resets under the action of the pressure spring, drawing air in through the one-way valve from the air inlet. By blowing air onto the blades through the nozzle, not only are the water droplets on the blades dispersed, preventing water from entering the protective shell, but the water droplets splashed when aquatic plants fall into the water are also dispersed, preventing the splashed water droplets from entering the protective shell through the through groove, thus preventing water from flowing into the protective shell.

[0018] The further improvement in the technical scheme of the utility model lies in that: the warning component comprises a box body, the box body is fixedly connected with the bottom plate, a button is arranged in the box body, a floating plate is slidably connected in the box body, an elastic spring is fixedly connected to one side of the floating plate close to the button, the other end of the elastic spring is fixedly connected with the bottom plate, and a warning lamp is arranged on the handle.

[0019] By adopting the above technical scheme, when the mower works on the water surface, the floating plate on the side of the air bag is pressed under the action of water, the elastic spring is in the compressed state, when the floating plate is pressed until touching the button, the controller receives the signal and controls the warning lamp on the handle to light up, so as to remind the staff that the distance between the water surface and the blade is too close, thereby preventing water from flowing into the protective shell.

[0020] The further improvement in the technical scheme of the utility model lies in that: the outer side of the floating plate is provided with a rubber sealing ring.

[0021] By adopting the above technical scheme, the rubber sealing ring arranged on the outer side of the floating plate can prevent water from flowing into the inside of the box body and thus affecting the normal work of the mower.

[0022] The further improvement in the technical scheme of the utility model lies in that: the waterproof shell is symmetrically provided with a guide block fixedly connected, a guide groove is formed in the protective shell, and the guide block is slidably connected with the guide groove.

[0023] By adopting the above technical scheme, the waterproof shell can be quickly assembled on the protective shell by cooperation of the guide block and the guide groove, so that the assembly time is saved, and the stability of the connection between the waterproof shell and the protective shell is improved.
