[0036] The following provides a detailed description of the specific embodiments of the present utility model in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present utility model and do not limit the present utility model.

[0037] In the present utility model, unless otherwise stated, the directional terms such as "upper", "lower", "inner", "outer", etc. included in the terms only represent the orientation of the terms in the normal use state, or the common names understood by those skilled in the art, and should not be regarded as a limitation to the terms.

[0038] As Figures 1-4 shown, the present utility model provides an automatic swing device, and the device includes: an operating rod 4 and a swing driving mechanism 5. One end of the operating rod 4 is detachably provided with a smoke machine body 3, and the opposite end thereof is connected to the driving end of the swing driving mechanism 5. The swing driving mechanism 5 is used to drive the connected end of the operating rod 4 to swing periodically, so as to realize the periodic swing of the smoke machine body 3 at the other end.

[0039] In the above solution, when the device is in use, the swing driving mechanism 5 drives one end of the operating rod 4 to swing periodically, thereby driving the smoke machine body 3 assembled on the opposite end thereof to swing periodically. In this way, the smoke machine body 3 can be automatically driven to swing and spray in a manner simulating manual operation, ensuring the spraying angle and range. The device can achieve the effect of automatic driving, and solve the inconvenience and fatigue problems of workers' operation.

[0040] In a preferred embodiment of the present utility model, the middle part of the operating rod 4 is rotatably assembled on the support rod 2 through a first rotating shaft 6, and the first rotating shaft 6 is perpendicular to the operating rod 4.

[0041] In the above solution, the operating rod 4 rotates around the first rotating shaft 6. The smoke machine body 3 and the swing driving mechanism 5 are respectively arranged at opposite ends of the operating rod 4. The swing driving mechanism 5 is used to drive one end of the operating rod 4 to swing, so that the smoke machine body 3 at the opposite end also swings.

[0042] In a preferred embodiment of the present utility model, the swing driving mechanism 5 includes: a driving unit 504, a first driving arm 503 and a second driving arm 501;

[0043] One end of the second driving arm 501 is rotatably assembled on the operating rod 4, and the opposite end thereof is rotatably connected to one end of the first driving arm 503. The other end of the first driving arm 503 is rotatably connected to the output end of the driving unit 504.

[0044] In the above solution, the driving unit 504 outputs a driving force to realize the rotation of one end of the first driving arm 503, and the connection structure of the first driving arm 503 and the second driving arm 501 is used to realize the swing driving effect of the second driving arm 501 on the operating rod 4.

[0045] In a preferred embodiment of the present utility model, one end of the second driving arm 501 is rotatably connected to the operating rod 4 through a second rotating shaft 507, and the opposite end thereof is rotatably connected to one end of the first driving arm 503 through a third rotating shaft 502. An extending connecting portion 505 is vertically provided at the other end of the first driving arm 503, and the extending connecting portion 505 is rotatably connected to the driving end of the driving unit 504; wherein,

[0046] The first rotating shaft 6, the second rotating shaft 507, the third rotating shaft 502 and the extending connecting portion 505 are arranged in parallel; the first driving arm 503 and the second driving arm 501 are respectively perpendicular to the third rotating shaft 502.

[0047] In the above solution, the driving unit 504 drives the extending connecting portion 505 to rotate about its own central axis, so that the first driving arm 503 rotates about the extending connecting portion 505, and the second driving arm 501 connected to the opposite end thereof is linked to drive the operating rod 4 to swing. In order to ensure the smoothness of the swing, it is necessary to ensure that the first rotating shaft 6, the second rotating shaft 507, the third rotating shaft 502 and the extending connecting portion 505 are arranged in parallel, so as to prevent the problem of rotational jamming.

[0048] In a preferred embodiment of the present utility model, a strip-shaped groove 506 is arranged along the length direction of the middle part of the first driving arm 503. The third rotating shaft 502 passes through the strip-shaped groove 506, and a limit nut is arranged at one end thereof, and the opposite end is rotatably connected to the second driving arm 501.

[0049] In the above solution, the structure of the strip-shaped groove 506 facilitates the adjustment of the assembly position of the third rotating shaft 502, and the adjusted position can be locked by the limit nut, so that the effective arm length of the first driving arm 503 can be adjusted to adjust the initial angle of the smoke machine body 3 and the size of the swing angle range to meet the different user requirements.

[0050] In a preferred embodiment of the present utility model, the driving unit 504 includes: a motor 5041 and a speed reducer 5042. The output shaft of the motor 5041 is connected to the speed reducer 5042, and a rotating driving hole is arranged on the speed reducer 5042. The extending connecting portion 505 is partially and limitedly inserted into the rotating driving hole to drive the extending connecting portion 505 to rotate about its own central axis.

[0051] In the above solution, on the one hand, the speed reducer 5042 can reduce the driving speed of the motor 5041 to ensure the frequency when the fog machine body 3 swings, preventing the spraying effect from being affected by too fast a frequency. On the other hand, it can achieve a change in the driving direction. The driving direction of the motor 5041 itself is the rotation direction of the output shaft. Through the adjustment of the speed reducer 5042, it can be changed into a rotation direction perpendicular to the output shaft, that is, the rotation direction of the rotation drive hole. In this way, when the extended connection part 505 is partially and limitedly inserted into the rotation drive hole, it can rotate accordingly. To ensure the effectiveness of the rotation, the rotation drive hole can be designed in a hexagonal shape or provided with a keyway. A protrusion is provided on the extended connection part 505 to cooperate with the keyway to prevent the extended connection part 505 from slipping during rotation.

[0052] In a preferred embodiment of the present invention, an assembly plate 7 is provided in the middle of the support rod 2, and the drive unit 504 is fixedly assembled on the assembly plate 7 through a fixing ring 8.

[0053] In a preferred embodiment of the present invention, the device further includes: a driving trolley mechanism 1, and the support rod 2 is vertically assembled on the driving trolley mechanism 1.

[0054] In the above solution, the driving trolley mechanism 1 can move the fog machine body 3. After moving to the destination, it is then swing-driven by the swing driving mechanism 5 to achieve automatic spraying. Equipment such as a medicine tank can be arranged on the driving trolley mechanism 1. Of course, an intelligent driving drive unit can also be arranged on the driving trolley mechanism 1 to facilitate the user to remotely drive and control it.

[0055] In a preferred embodiment of the present invention, the driving trolley mechanism 1 includes: a vehicle frame 101, and a plurality of wheels 102 are rotatably provided on both sides of the vehicle frame 101 respectively.

[0056] In summary, when the automatic swing device provided by the present invention is in use, it can perform automatic swing operations on the fog machine, which can not only save labor, but also work for a long time without affecting the reduction of labor force resulting in a smaller swing amplitude and a reduced spraying effect. Moreover, the driving trolley mechanism 1 is provided, which can carry equipment such as a medicine tank, and also does not require the user to carry it manually, saving physical strength. With the intelligent driving drive unit, the user can remotely drive and control it, greatly improving the convenience of use.
