Description

Technical Field

[0001] This invention relates to a sprayer for watering gardens and green spaces, specifically an automatic rotary sprayer. Background Technology

[0002] Currently, automatic rotary sprinklers are required for watering landscaping. Their structure mainly consists of a sprinkler pipe, a water inlet channel inside the sprinkler pipe, and a mounting sleeve that is fitted onto the bottom of the sprinkler pipe. The automatic rotary sprinkler is fixedly installed in the water inlet pan through the mounting sleeve. When the water inlet pan supplies water into the water inlet channel and sprays it from the top of the main body for watering, the water pressure will cause the main body to rotate relative to the mounting sleeve, thus forming a 360° spray irrigation. However, in some situations, spraying does not require a 360° range; it only needs to oscillate left and right within a certain angle for spraying. In such cases, a corresponding mechanism needs to be designed to limit the oscillation. However, the existing mechanisms have relatively simple structural designs, mostly using an exposed movable lever to block the spray nozzle and limit the spray angle. Because the structure is exposed, it is prone to damage in actual use, resulting in poor reliability. Moreover, the overly rudimentary structure also makes the appearance very unsightly. In addition, with the continuous expansion of the landscaping irrigation market, many consumers are eager for manufacturers to launch more automatic rotary sprinklers with different structures and implementation methods to meet market demand. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide an automatic rotary sprayer that is aesthetically pleasing, compact in structure and reliable in use.

[0004] The technical problem of this invention is solved by the following technical solution:

[0005] An automatic rotating sprinkler includes a sprinkler pipe, a water inlet channel disposed within the sprinkler pipe, and a mounting sleeve movably fitted at the bottom of the sprinkler pipe. The sprinkler pipe has an air inlet chamber and an elastic sealing mechanism installed within the air inlet chamber. The elastic sealing mechanism has a switching lever. A left air inlet and a right air inlet, respectively, are located on opposite sides of the top of the sprinkler pipe and connect to the water inlet channel. These two air inlets connect to the air inlet chamber via left and right air inlets, respectively. Driven by the switching lever, the elastic sealing mechanism alternately closes the left and right air inlets, causing water in the water inlet channel to spray out from the top of the sprinkler pipe, creating a pressure imbalance between the left and right sides. This, in turn, causes the sprinkler pipe to swing left and right relative to the mounting sleeve, spraying water. The left and right swinging water spraying of the sprinkler pipe relative to the mounting sleeve simultaneously drives the switching lever to alternately close the left and right air inlets, thus forming a continuous automatic left and right swinging water spraying from the sprinkler pipe.

[0006] The elastic sealing mechanism includes a reversing rod and a switching lever. The top of the reversing rod is provided with a sealing ball head, and the bottom of the reversing rod is hinged to the top of the switching lever. The bottom of the switching lever extends downward into the air intake chamber. A tension spring is provided between the reversing rod and the switching lever for elastic connection. The left and right swinging water spray of the spray pipe relative to the mounting sleeve simultaneously drives the bottom of the switching lever to swing left and right, and the tension spring elastically pulls the sealing ball head at the top of the reversing rod to swing left and right, thereby alternately sealing the left and right air supply channels.

[0007] The spray pipe consists of a body, a nozzle sealed on the top of the body, and a spindle sealed on the bottom of the body. The nozzle, body, and spindle are provided with interconnected water inlet channels.

[0008] The nozzle is bent outward relative to the body, and the left and right air inlets are respectively located on the left and right sides of the nozzle; the mounting sleeve is movably mounted on the outside of the spindle, and the reciprocating rotation of the spindle relative to the mounting sleeve drives the nozzle to swing left and right to spray water.

[0009] The main body is provided with a cover, and an air intake cavity is formed between the cover and the main body.

[0010] The cover has a left air inlet and a right air inlet on each side, which are connected to the air inlet chamber. It also has a left air duct cover and a right air duct cover installed on the outer surface of the cover. The left air duct cover and the cover form a left supplementary air duct, which is connected to the left supplementary air inlet and the left air inlet. The right air duct cover and the cover form a right supplementary air duct, which is connected to the right supplementary air inlet and the right air inlet. The elastic sealing mechanism is driven by the switching lever to alternately close the left and right air inlets.

[0011] Both the left and right air inlets are equipped with sealing plugs.

[0012] The mounting sleeve has two movable angle adjustment rings in the middle, each with a limit block. The two angle adjustment rings rotate relative to the mounting sleeve, causing the two limit blocks to form an adjustable angle limit stroke. The switching lever is set within this limit stroke and is driven by the left and right swinging water spray of the spray pipe to alternately touch the two limit blocks, thereby driving the elastic sealing mechanism to alternately close the left and right air supply channels.

[0013] The mounting sleeve has mounting threads at the bottom and multiple sealing gaskets at the bottom end.

[0014] The nozzle has a nozzle cap at the front end, and the water inlet channel forms a spray chamber inside the nozzle.

[0015] Compared with the prior art, the present invention mainly features an air inlet chamber outside the spray pipe and an elastic sealing mechanism installed inside the air inlet chamber. This elastic sealing mechanism has a switching lever. The top of the spray pipe has left and right air inlets connected to the water inlet channel, respectively. These left and right air inlets are connected to the air inlet chamber via left and right air inlets, respectively. During operation, the elastic sealing mechanism is driven by the switching lever to alternately close the left and right air inlets. This causes the water in the water inlet channel to spray out from the top of the spray pipe, creating a pressure imbalance between the left and right sides. This pressure imbalance then drives the spray pipe to swing left and right relative to the mounting sleeve. Furthermore, the left and right swinging water spray of the spray pipe relative to the mounting sleeve simultaneously drives the switching lever to alternately close the left and right air inlets, thus forming a continuous automatic left and right swinging water spray. Therefore, this concealed design structure has advantages such as aesthetic appearance, compact structure, and reliable use, better meeting market demand. Attached Figure Description

[0029] An automatic rotary sprayer, such as Figure 1 , Figures 7-11 As shown, this relates to a garden irrigation product, whose structure mainly consists of a spray pipe 1, a water inlet channel 10 set inside the spray pipe, and an installation sleeve 2 that is movably fitted at the bottom of the spray pipe.

[0030] The spray pipe 1 includes a nozzle 13, a body 11 and a spindle 12. The nozzle 13, body 11 and spindle 12 are provided with interconnected water inlet channels 10. The water inlet channel 10 in the nozzle 13 forms a special, funnel-shaped spray chamber 101.

[0031] The top of the body 11 is bent outward to form a "7" shape. The nozzle 13 is installed in the port on the top of the body 11 by tightening and sealing the O-ring thread. Therefore, the nozzle 13 is also bent outward relative to the body 11. The left and right sides of the nozzle 13 are respectively provided with a left air supply hole 303 and a right air supply hole 313. The left and right air supply holes are connected to the spray chamber 101 inside the nozzle 13. The nozzle 13 is provided with a nozzle cover 5 at the front end.

[0032] The spindle 12 is installed in the port at the bottom of the body 11 by tightening and sealing the O-ring thread. The mounting sleeve 2 is movably mounted on the outside of the spindle 12. The spindle and the mounting sleeve are on the same axis and intersect the axis of the nozzle 13 at an angle. Therefore, when the spindle 12 reciprocates relative to the mounting sleeve 2 around the axis, it can drive the nozzle 13 to swing left and right to spray water.

[0033] The mounting sleeve 2 has a mounting thread 21 at the bottom and a multi-layer sealing gasket 22 at the bottom end. The automatic rotary sprayer is screwed onto the water inlet pan (not shown in the figure) by the mounting thread 21 at the bottom of the mounting sleeve 2, and the multi-layer sealing gasket 22 forms an installation seal. The multi-layer sealing gasket 22 can be a combination of rubber gasket and polytetrafluoroethylene gasket.

[0034] The spray pipe 1 is provided with an air inlet chamber 300 and an elastic sealing mechanism 6 installed in the air inlet chamber. The air inlet chamber 300 is constructed by having a cover 3 outside the main body 11, forming the air inlet chamber 300 between the cover and the main body. Simultaneously, the cover 3 has a left air inlet 301 and a right air inlet 311 on its left and right sides, respectively, communicating with the air inlet chamber 300. A left air duct cover 30 and a right air duct cover 31 are welded and fixed to the outer surface of the cover 3. The left air duct cover 30 is connected to the cover 3. A left air supply channel 302 is formed, and the left air supply channel is connected to the left air supply hole 303 on the left side of the nozzle 13 and the left air inlet hole 301 on the left side of the cover 3. A right air supply channel 312 is formed between the right air supply cover 31 and the cover 3, and the right air supply channel is connected to the right air supply hole 313 on the right side of the nozzle 13 and the right air inlet hole 311 on the right side of the cover 3. The left and right air supply holes and the left and right air supply channels, together with the rubber plugs 32 in the left and right air inlets, can form a complete left and right air supply channel.

[0035] The elastic sealing mechanism 6 includes a reversing rod 61 and a switching lever 62. The top end of the reversing rod 61 is provided with a sealing ball head 611. The bottom end of the reversing rod 61 and the top end of the switching lever 62 are hinged by screws, that is, the bottom end of the reversing rod 61 and the top end of the switching lever 62 can rotate around the screws. The bottom end of the switching lever 62 extends downward into the air intake chamber 300. A tension spring 64 is provided between the reversing rod 61 and the switching lever 62 for elastic connection. Specifically, the two ends of the tension spring are respectively connected to the connecting post 63 in the middle of the reversing rod 61 and the middle of the switching lever 62.

[0036] The mounting sleeve 2 has two movable angle adjustment rings 4 in the middle, which means that the two angle adjustment rings can rotate freely in the middle of the mounting sleeve 2. Each angle adjustment ring 4 is provided with a limit block 41. When the two angle adjustment rings 4 rotate relative to the mounting sleeve 2, they can drive the two limit blocks 41 to form an adjustable angle limit stroke. The bottom end of the switching lever 62 extends downward into the air inlet chamber 300 and is set within this limit stroke. Therefore, the lower end of the switching lever 62 can be driven by the left and right swing spray of the spray pipe 1 to alternately touch the two limit blocks 41, thereby driving the elastic sealing mechanism 6 to alternately close the left and right air supply channels. That is, the spraying range of the automatic rotating sprayer will be limited to the stroke range defined by the two limit blocks 41.

[0037] The working process of the present invention is as follows: When the switching lever 62 is located at the leftmost or rightmost limit stroke, that is, when the bottom end of the switching lever 62 is driven to swing left and right, the sealing ball head 611 at the top of the reversing rod 61 will also swing left and right through the tension spring 64 and alternately contact the rubber plugs 32 of the left and right air inlets, thereby alternately sealing the left and right air inlets, and causing the left and right air supply channels and the left and right air supply holes to also form corresponding alternate sealing, so that when the water in the water inlet channel 10 is sprayed out from the nozzle cover 5 of the nozzle 13, it will cause left and right pressure imbalance, and finally drive the nozzle 13 of the spray pipe 1 to swing left and right relative to the mounting sleeve 2 to spray water.

[0038] The left and right swinging water spraying of the spray pipe 1 relative to the mounting sleeve 2 simultaneously drives the left and right swinging of the bottom end of the switching lever 62, thereby forming a continuous automatic left and right swinging water spraying of the spray pipe 1.

[0039] The working principle of the nozzle 13 causing left and right oscillation spraying due to left and right pressure imbalance during spraying is as follows: When the water flows through the spray chamber 101 inside the nozzle 13, the water column will divide the spray chamber into two chambers, left and right. Because the high-speed water jet will draw the air in the spray chamber 101 out of the nozzle 13 and form a low-pressure area, the left and right air replenishment holes at the bottom of the spray chamber 101 will replenish air from the atmosphere to maintain pressure balance.

[0040] When the left air inlet 303 or the right air inlet 313 is blocked, resulting in a one-sided inability to replenish air, the pressure will become unbalanced, causing the high-speed water jet to deflect. Due to the reaction force, this deflected water jet can drive the spray pipe 1 to rotate to one side. Therefore, alternating the closure of the left and right air inlets will cause the spray pipe 1 to swing left and right.

[0041] Clearly, this concealed design offers advantages such as aesthetic appeal, compact structure, and reliable operation, thus better meeting market purchasing needs.

[0042] The above description is merely a specific embodiment of the present invention. Those skilled in the art should understand that any structural design equivalent to this embodiment should be included within the protection scope of the present invention.
