[0053] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0054] like Figure 1 and Figure 3 As shown, the utility model provides a sprinkler, comprising a water inlet assembly 1, a sprinkler assembly 2, a driving assembly 3 and a triggering assembly 4, wherein the sprinkler assembly 2 is connected to the water inlet assembly 1 and can rotate relative to the water inlet assembly 1; the driving assembly 3 is connected to the water inlet assembly 1 and the sprinkler assembly 2, and is used to drive the sprinkler assembly 2 to rotate relative to the water inlet assembly 1; the triggering assembly 4 comprises two sensing elements 41 and a triggering member 42, the two sensing elements 41 are arranged at intervals on the water inlet assembly 1, the triggering member 42 is connected to the sprinkler assembly 2, and can rotate with the sprinkler assembly 2 and selectively trigger any one of the sensing elements 41, and when triggered, the sprinkler assembly 2 is controlled to rotate in the opposite direction through the driving assembly 3.

[0055] The water inlet assembly 1 is responsible for introducing water, and the water enters the sprinkler assembly 2 through the water inlet assembly 1, and the sprinkler assembly 2 sprays the water to the designated area; the drive assembly 3 is started, and the drive assembly 3 drives the sprinkler assembly 2 to rotate relative to the water inlet assembly 1. When the trigger 42 rotates to the position of one of the sensing elements 41, the sensing element 41 will be triggered, thereby controlling the sprinkler assembly 2 to rotate in the opposite direction through the drive assembly 3, so that the sprinkler assembly 2 swings back and forth within a certain angle range, and can automatically sprinkle water within the set range. Through the cooperation of the trigger assembly 4 and the drive assembly 3, the sprinkler cannon can automatically adjust the spraying range without manual intervention, thereby improving the watering efficiency.

[0056] like Figure 3 As shown, in one embodiment, the sprinkler assembly 2 is provided with a plurality of fixed positions, and the plurality of fixed positions are spaced apart around the rotation axis of the sprinkler assembly 2; the trigger member 42 can be fixed at any fixed position.

[0057] By setting a plurality of fixed positions, when the trigger member 42 is fixed at different fixed positions, the direction of the spraying range of the sprinkler will change, thereby meeting the sprinkler requirements of different scenes.

[0058] like Figure 3 As shown, in one embodiment, the sensing element 41 is a micro switch, and the triggering member 42 acts on the spring of the micro switch to trigger the micro switch.

[0059] By setting the sensing element 41 as a micro switch, the triggering member 42 triggers the spring of the micro switch, so that the driving member controls the watering assembly 2 to rotate in the reverse direction.

[0060] It should be understood that the micro switch is electrically connected to the circuit of the drive motor 31 .

[0061] It should be understood that the sensing element 41 may also be a magnetic induction switch, in which case the triggering member 42 is a magnet.

[0062] like Figure 3 As shown, in one of the embodiments, a roller 43 is provided on the side of the spring piece facing the sprinkler assembly 2 , and the roller 43 is rotatably connected to the spring piece and can abut against the rotating trigger member 42 .

[0063] By providing the roller 43, the roller 43 abuts against the trigger member 42 instead of the abutment between the spring and the trigger member 42. The rolling contact of the roller 43 can reduce the contact resistance between the trigger member 42 and the spring, so that the trigger member 42 can trigger the micro switch more easily, thereby improving the sensitivity of the sprinkler. Compared with the sliding contact, the roller 43 and the trigger member 42 are in rolling contact, and the rolling contact can significantly reduce the friction, thereby reducing wear and improving the service life of the trigger member 42 and the spring.

[0064] like Figure 3 As shown, in one embodiment, the fixed position is a fixing hole opened in the sprinkler assembly 2; the trigger member 42 includes a first fixing bar 421 and a second fixing bar 422, the first fixing bar 421 is arranged between the two sensing elements 41 and along the rotation axis of the sprinkler assembly 2, the second fixing bar 422 is connected to the first fixing bar 421, and is arranged perpendicular to the rotation axis of the sprinkler assembly 2, and the second fixing bar 422 can be selectively fixed to any fixing hole.

[0065] When the sprinkler assembly 2 rotates, the first fixing bar 421 and the second fixing bar 422 are driven to rotate. The first fixing bar 421 is located between the two sensing elements 41 . The rotating first fixing bar 421 can abut against the sensing element 41 , thereby triggering the sensing element 41 .

[0066] It should be understood that the trigger member 42 may also be a protrusion disposed on the surface of the sprinkler assembly 2 .

[0067] It should be understood that the second fixing strip 422 can be fixed to the fixing hole by screws, bolts, buckles, etc.

[0068] like Figure 7 As shown, in one embodiment, the sprinkler assembly 2 is provided with a slide groove, which is coaxial with the rotation axis of the sprinkler assembly 2; the trigger member 42 also includes a slider 423, a limit pin 424 and an elastic portion 425, the slider 423 is connected to the first fixing bar 421 and can be slidably arranged in the slide groove, the limit pin 424 is arranged relative to the fixing hole and can be slidably connected to the second fixing bar 422, the limit pin 424 can be inserted into or detached from the fixing hole, and the elastic portion 425 connects the limit pin 424 and the second fixing bar 422, and is used to provide elastic force for the limit pin 424 to be inserted into the fixing hole.

[0069] When the position of the trigger member 42 needs to be adjusted, the limit pin 424 is controlled to slide so that the limit pin 424 slides out of the fixing hole, and then the slider 423 is slid. The slider 423 drives the first fixing bar 421 and the second fixing bar 422 to slide, thereby adjusting the positions of the first fixing bar 421 and the second fixing bar 422. When the first fixing bar 421 and the second fixing bar 422 slide to the preset position, the limit pin 424 is released. Under the action of the elastic part 425, the limit pin 424 is slidably inserted into the fixing hole, thereby fixing the first fixing bar 421 and the second fixing bar 422.

[0070] It should be understood that the elastic portion 425 can be a spring, a rubber strip, a rubber block, etc.

[0071] like Figure 3 As shown, in one embodiment, the second fixing bar 422 is provided with a mounting hole relative to the fixing hole, and the limiting pin 424 can be slidably inserted in the mounting hole.

[0072] By inserting the limiting pin 424 into the mounting hole, a sliding connection between the limiting pin 424 and the second fixing bar 422 is achieved.

[0074] The motor is started, and the motor drives the water sprinkling assembly 2 to rotate through the transmission assembly 32, thereby realizing the rotation of the water sprinkling assembly 2 relative to the water inlet assembly 1.

[0075] It should be understood that the driving assembly 3 may also be a combination of a hydraulic motor and a transmission assembly 32 .

[0076] It should be understood that the transmission assembly 32 can be a belt transmission mechanism, a gear transmission mechanism, or a gear chain transmission mechanism.

[0077] like Figure 4 and Figure 5 As shown, in one embodiment, the transmission assembly 32 includes a first gear 321, a transmission cylinder 322, and a second gear 323.

[0078] The driving motor 31 is started, and the driving motor 31 drives the first gear 321 to rotate. The first gear 321 is in transmission connection with the second gear 323, and drives the second gear 323 to rotate. The second gear 323 drives the transmission tube 322 to rotate, and the transmission tube 322 drives the sprinkler assembly 2 to rotate.

[0079] It should be understood that the first gear 321 and the second gear 323 can be connected via a chain (not shown in the figure), the first gear 321 can also directly mesh with the second gear 323, or the first gear 321 and the second gear 323 can also mesh through gears.
