Description
Technical Field
The utility model relates to the technical field of agriculture and forestry equipment, in particular to a lithium electric hedge trimmer.
Background
The hedge trimmer is also called as hedge trimmer, and is suitable for trimming tea leaves, park, garden, roadside hedge and other landscaping. In the operation process of the hedge trimmer, the transmission system, the motor and the controller all generate more heat, so that the temperature of the machine body is too high (the temperature can exceed 80 degrees in continuous operation), thereby generating the following problems: 1. poor machine use experience (high body temperature, easy to touch the body by operators when using the machine); 2. the controller is easy to overheat and protect, so that the service life of the controller is greatly reduced, and if the temperature resistance level of components is improved, the cost is greatly increased. In order to solve the above problems, it is necessary to cool the controller and the hedge trimmer body by designing a cooling structure to reduce the temperature.
In the prior art, the motor cooling structure of the hedge trimmer is as shown in fig. 1 and 2: the motor is provided with a plurality of air inlets a, A1 is a motor end cover, A2 is a motor cooling fan, a plurality of air outlets b are formed in the lower periphery of the motor end cover A1, when the motor rotates, air flows to the periphery through the air outlets b on the motor end cover A1 under the action of centrifugal force under the driving of the cooling fan A2, negative pressure is formed in the motor, and the air enters the motor from the air inlets a. Thereby, the air forms a continuous air flow through the motor, thereby cooling the motor.
As can be seen from the above, the existing motor cooling structure of the lithium-ion hedge trimmer has the disadvantage that the cooling air is dispersed by 360 ° after passing through the motor, and only the motor can be cooled, and the controller and the machine body cannot be cooled well. Although the motor is designed with a fan, the whole machine is not provided with an air inlet channel and an air outlet channel, so that the motor fan does not work, the controller and the motor cannot be cooled, and the reliability of the machine is poor.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art and provides a lithium electric hedge trimmer for solving the technical problems.
In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows: a lithium electric hedge trimmer comprises a control handle assembly, a motor housing, a motor bottom shell, a reduction gearbox, a controller, a handle assembly and a cutter assembly; the motor bottom shell is provided with a motor support body, the motor is assembled on the motor support body, and the stator of the motor and the motor support body divide the space between the motor outer cover and the motor bottom shell into two parts which are not communicated with each other; the inner side of the motor support body is provided with a plurality of first air inlets, and the outer side of the motor support body is provided with a plurality of second air inlets; the side wall of the motor support body is provided with an air outlet hole towards the controller; a cooling fan is arranged below the motor.
Preferably, the upper and lower surfaces of the turntable of the cooling fan are respectively and uniformly provided with a plurality of fan blades.
The beneficial effects are that: compared with the prior art, when the motor works, the cooling fan is driven to rotate at a high speed, the fan blades rotate, and air is blown out under the action of centrifugal force, so that air flow is formed. Air entering from the first air inlet hole flows to the cooling reduction gearbox and the controller through the air outlet hole under the blowing of the fan blade at the bottom surface of the cooling fan turntable; and the air entering from the second air inlet hole is blown by the fan blades on the cooling fan turntable to cool the motor and the controller in sequence. Therefore, the cooling air is two-way two-sided air inlet, so that the air inlet is increased, and the motor, the reduction gearbox, the motor bottom shell and the controller can be cooled simultaneously, thereby greatly improving the cooling effect of the whole machine.

Detailed Description
The utility model is further described below with reference to the drawings and specific embodiments.
Examples
Referring to fig. 3, the lithium-ion hedge trimmer of the present embodiment includes a handle assembly 1, a motor 2, a motor housing 3, a motor bottom case 7, a reduction gearbox 51, a controller, a handle assembly 4, and a cutter assembly 5.
As shown in fig. 4, the motor bottom shell 7 is provided with a motor support 74, the motor 2 is assembled on the motor support 74, and the stator of the motor 2 and the motor support 74 divide the space between the motor housing 3 and the motor bottom shell 7 into two parts which are not communicated with each other to form two air inlet channels; the inner side of the motor support body 74 is provided with a plurality of first air inlets 71, and the outer side of the motor support body is provided with a plurality of second air inlets 72; an air outlet hole 73 is formed in the side wall of the motor support body 74 towards the controller; a cooling fan 6 is installed below the motor 2. As shown in fig. 5, a plurality of fan blades 61 are uniformly fixed on the upper and lower surfaces of the turntable of the cooling fan 6.
When the motor 2 works, the cooling fan 6 is driven to rotate at a high speed, the fan blades 61 rotate, and air is blown out under the action of centrifugal force to form air flow. The air entering from the first air inlet hole 71 flows to the cooling reduction box 51 and the controller through the air outlet hole 73 under the blowing of the fan blades on the bottom surface of the turntable of the cooling fan 6; the air entering through the second air inlet hole 72 is blown by the fan blades on the turntable of the cooling fan 6 to cool the motor and the controller in sequence. Therefore, the cooling air is two-way two-sided air inlet, so that the air inlet is increased, and the motor, the reduction gearbox, the motor bottom shell and the controller can be cooled simultaneously, thereby greatly improving the cooling effect of the whole machine.
