Description

Electric lawn mower

The invention relates to an electric lawn mower.

According to the increase of environmental protection awareness in recent years, electric lawn mowers have generally replaced fuel lawn mowers with electric lawn mowers. Electric lawn mowers have the advantages of low noise, no exhaust pollution, and avoiding fuel leakage and fire. The known electric lawn mower has a rod body, a base body and a control portion provided at both ends of the rod body. The base body is provided with a rotor motor. When the rotor shaft is driven by the rotor of the rotor motor to rotate, the shaft shaft will drive the sleeve. When the blade set on the rotating shaft rotates, the mowing operation can be carried out. When using, it is held with one hand on the middle part of the base and the control part, and the other hand is held on the control part to control the motor, as disclosed in TWM526804. Such is the electric lawn mower.

However, when such conventional electric lawnmowers are used, the elbows held on the control part must be bent sharply and the wrists must also be bent to hold the control part smoothly. When used for a period of time, it will cause muscle and Joint aches, you need to rest before you can continue to work, which will reduce work efficiency, and long-term use will lead to occupational injuries such as joint injuries, there are shortcomings that need to be improved.

Therefore, it is necessary to provide a novel and progressive electric lawn mower to solve the above problems.

The main purpose of the present invention is to provide an electric lawn mower that allows users to hold it in an ergonomic manner during use for long-term operation without causing muscle and joint soreness to increase work efficiency. And avoid occupational injuries such as joint injuries.

To achieve the above object, the present invention provides an electric lawn mower, which includes a straight rod section, a grip section and a head. The grip section is disposed at one end of the straight rod section, the grip section is provided with a control handle, and a first included angle exists between the length direction of the grip section and the length direction of the straight rod section, and the first included angle Between 25 and 65 degrees. The seat head is disposed at one end of the straight rod section opposite to the grip section, and includes a rotation motor having a rotating shaft. A second included angle is formed between a radial direction of rotation of the rotating shaft and a length direction of the straight rod section. The second included angle is between 25 degrees and 65 degrees.

The following only illustrates the possible implementation aspects of the present invention by way of examples, but is not intended to limit the scope of the present invention to be protected, which will be described first.

Please refer to FIGS. 1 to 3, which show a preferred embodiment of the present invention. The electric lawn mower of the present invention includes a straight rod section 1, a grip section 2 and a head 3.

The grip section 2 is disposed at one end of the straight rod section 1. The grip section 2 is provided with a control handle 21, and a first angle is formed between the length direction of the grip section 2 and the length direction of the straight rod section 1. Θ1, the first included angle Θ1 is between 25 degrees and 65 degrees.

The seat head 3 is disposed at one end of the straight rod section 1 opposite to the grip section 2 and includes a rotation motor 31 having a rotating shaft 32. One of the rotating shafts 32 rotates in a radial direction 33 and the straight rod section 1 There is a second included angle Θ2 between the longitudinal directions, and the second included angle Θ2 is between 25 degrees and 65 degrees.

Preferably, the first included angle Θ1 and the second included angle Θ2 are between 30 degrees and 45 degrees, and the first included angle Θ1 and the second included angle Θ2 are the same. The grip section 2 is opposite to the straight rod section. 1 is bent away from the seat head 3, and the seat head 3 is bent away from the grip section 2 with respect to the straight rod section 1. In this embodiment, the first included angle Θ1 and the second included angle Θ2 are 35. In this way, the elbow and wrist held by the user in the grip section 2 can be held in the straight state and held on the control handle 21 without bending, and the user's arm muscles are less forceful, so they can work for a long time without Will cause sore muscles and joints of the user's arm to increase work efficiency.

Specifically, the control handle 21 is disposed at one end of the grip section 2 away from the straight rod section 1. The control handle 21 is provided with a handle 211, a control key 212 is provided on the handle 211, and the control handle 21 is further provided with a guard bow 213 surrounding the control key 212. When in use, it is grasped and held by the hand to assist the hand The handle 211 and the control key 212 are pressed to control the operation of the rotation motor 31.

Further, the grip section 2 includes a bending rod 22 connected between the straight rod section 1 and the control handle 21, and the bending rod 22 and the straight rod section 1 are formed between the bending rod 22 and the control handle 21. The first included angle Θ1.

The length of the control handle 21 defines a first length L1, and the length of the bending lever 22 defines a second length L2. The ratio of the first length L1 to the second length L2 is between 4: 2 and 5 : 2, in this embodiment it is 4.5: 2.

In detail, the electric lawn mower further includes a first rod body 11 and a second rod body 12, one end of the first rod body 11 is connected to the seat head 3, and the other end of the first rod body 11 is connected to The second rod body 12 is sleeved together, and the bent rod 22 is integrally connected to an end of the second rod body 12 away from the first rod body 11 to have strong structural strength.

Preferably, the second lever body 12 is further provided with a handle 4 for holding by the other hand of the user. The distance between the handle 4 and the grip section 2 defines a third length L3, and the grip The length of segment 2 is defined as a fourth length L4, and the ratio of the third length L3 to the fourth length L4 is 3.5: 6.5. This ratio allows the user to straighten both elbows and wrists to reduce The burden of two elbows and two wrists, the user can simply hold the handle 4 and the control handle 21 with the pointing force of the palm of his hand, which can relax both arms and improve the working time.

It is also worth mentioning that the length of the straight rod segment 1 defines a fifth length L5, and the ratio of the fifth length L5 to the fourth length L4 is between 19.5: 6.5 and 16.5: 6.5, which in this embodiment is 18: 6.5, when the user holds the handle 4 and the control handle 21, the weight of the grip section 2 and the seat head 3 can be maintained at a balance so that the grip section 2 is maintained in a horizontal direction, so that The burden on the wrist held by the control handle 21 is reduced.

In summary, the electric lawn mower of the present invention allows the user's two elbows and two wrists to be held in the control handle in a straight state without bending, and the user's arm muscles need less effort, so they can work for a long time. Will not cause sore muscles and joints of the user's arm, so as to increase work efficiency.
