Description

Technical Field

[0001] The present application relates to the field of garden power tools, and in particular to a speed control button mounting structure and a garden blower. Background Art

[0002] A backpack garden blower is a commonly used garden power tool, which is mainly used to use airflow to clean fallen leaves, grass clippings, road dust, snow, etc.

[0003] The backpack garden blower mainly includes a backpack frame, a shell installed on the backpack frame, a battery pack, a motor, a fan arranged in the shell, and a purge pipe connected to the shell and used to discharge the high-speed airflow generated by the fan. A handle is installed on the purge pipe, and a speed control button is installed on the shell of the handle. When assembling the handle shell, the speed control button is first installed on the shell unit, and then the shell unit with the speed control button installed is spliced ​​with another shell unit to form a handle shell. However, in the actual assembly process, before the two shell units are spliced, the speed control button installed on one of the shell units is prone to loosening or shifting, affecting the assembly efficiency of the handle shell. Utility Model Content

[0004] The purpose of at least one specific embodiment of the present utility model is to solve the defects of the prior art and provide a speed control button installation structure and a garden blower.

[0034] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0035] Example 1

[0036] Reference Figure 1 , Figure 2A speed control button mounting structure 100 includes a first housing unit 10, a speed control button 20 rotatably mounted on the first housing unit 10, and an elastic member 30 mounted in the first housing unit 10 and supported on the bottom of the speed control button 20. A protrusion 40 is provided on one side of the first housing unit 10, and the protrusion 40 forms a receiving cavity 50 on one side of the first housing unit 10.

[0037] Reference Figure 3 , Figure 4 The speed regulating button 20 includes a connecting portion 201 and a button portion 202, wherein the connection between the connecting portion 201 and the button portion 202 forms a card interface 203; the protruding portion 40 is provided with a mounting opening 401, and the mounting opening 401 is provided with a card connection portion 402;

[0038] When the speed regulating button 20 is installed on the first housing unit 10 , the connecting portion 201 extends into the accommodating cavity 50 , the button portion 202 is located at the installation opening 401 and supported by the elastic member 30 , and the card interface 203 is engaged with the card connection portion 402 .

[0039] In this embodiment, a support portion 501 is provided on the inner wall of the accommodating cavity 50 , and the elastic member 30 is located in the accommodating cavity 50 . One end of the elastic member 30 abuts against the support portion 501 , and the other end abuts against the bottom of the button portion 202 .

[0040] In some embodiments, the elastic member 30 is a spring, which is installed at the bottom of the button portion 202. The elastic member 30 mainly provides the button portion 202 with the required restoring force after being pressed, ensuring that the button portion 202 can bounce back and reset after being pressed.

[0041] Furthermore, in order to improve the stability of the installation of the elastic member 30, a positioning column 204 is provided at the bottom of the button portion 202. When the elastic member 30 is supported on the bottom of the button portion 202, the positioning column 204 is plugged into the end of the elastic member 30. When the end of the elastic member 30 contacts the bottom of the button portion 202, it is not easy to loosen.

[0042] Reference Figure 5 , Figure 6When the speed regulating button mounting structure 100 is actually used, the speed regulating button 20 and the elastic member 30 are first installed on the first housing unit 10, and then the first housing unit 10 and the second housing unit 60 are spliced ​​to form the handle 200. Through the design of the speed regulating button mounting structure 100, when the speed regulating button 20 is installed, its connecting portion 201 passes through the mounting opening 401 and extends into the inner side of the first housing unit 10, and the button portion 202 is located at the mounting opening 401. At this time, the card interface 203 is engaged with the card connection portion 402, and the speed regulating button 20 can be quickly assembled on the first housing unit 10 without additional fixing parts. At the same time, the elastic member 30 is installed on the inner side of the first housing unit 10, and one end of the elastic member 30 conflicts with the support portion 501, and the other end conflicts with the bottom of the button portion 202. The elastic part 30 can be stably installed on the inner side of the first shell unit 10. After completing the above assembly action, the speed control button 20 can be directly clamped at the installation port 401 of the first shell unit 10 without loosening. The elastic part 30 can be installed on the inner wall surface of the first shell 10 and supported at the lower position of the speed control button 20 without loosening. Before the first shell unit 10 and the second shell unit 60 are spliced ​​together, the speed control button 20, the elastic part 30 and the first shell unit 10 can be quickly assembled into a whole. After the first shell unit 10 and the second shell unit 60 are spliced ​​together to form the handle 200, the speed control button 20 and the elastic part 30 can be quickly assembled to the handle 200 together. During the entire assembly process, the speed control button 20 and the elastic part 30 are not easy to loosen, and the assembly of multiple accessories is convenient and quick.

[0043] During actual installation, a positioning pin 601 is provided on the inner wall of the second shell unit 60, and a speed control switch 210 is fixedly installed on the inner side of the second shell unit 60. After the speed control button 20 is installed on the first shell unit 10, when the first shell unit 10 and the second shell unit 60 are spliced, the connecting part 201 of the speed control button 20 is aligned with the positioning pin 601 and rotated to be connected. After the first shell unit 10 and the second shell unit 60 are spliced ​​to form the handle 200, the speed control switch 210 is fixedly installed on the inner wall of the second shell unit 60 and is covered by the accommodating cavity 50 on the first shell unit 10. The button part 202 is located on one side of the speed control switch 210. The button part 202 can swing around the positioning pin 601 as the center. The button part 202 can touch the speed control switch 210 by pressing, thereby achieving the purpose of speed adjustment.

[0044] Furthermore, the first shell unit 10 is also provided with a pressing activity area 70. After the speed control button 20 is installed on the first shell unit 10, the button portion 202 passes through the installation opening 401 and is located in the pressing activity area 70. When the handle 200 is held by a person's palm, the pressing activity area 70 corresponds to the thumb activity area of ​​the human body. The human thumb can contact the button portion 202 of the speed control button 20 during inertial swing. This design is more ergonomic and improves the convenience and comfort of the user during the speed control process.
