For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] The following is a further detailed description of the quick-insert, closable and adjustable spray head of the utility model in conjunction with the accompanying drawings.

[0033] Combined with Figure 1-8 The specific implementation process of the utility model of a quick-insert, closable and adjustable spray head is as follows:

[0034] A quick-insert, closable and adjustable spray head, comprising a quick-insert connector 1, an adjustable nozzle 2 and a nozzle cap 3; the top of the quick-insert connector 1 is detachably connected to the bottom of the adjustable nozzle 2, and the bottom of the quick-insert connector 1 can be quickly plugged into a water inlet pipe; the adjustable nozzle 2 comprises a nozzle seat 21 and a flow control plug 22, and the flow control plug 22 is inserted into the nozzle seat 21 from the top of the nozzle seat 21 downward;

[0035] The flow control plug 22 includes a baffle 221 and a diverter plug 222. The diameter of the baffle 221 is larger than the diameter of the water flow channel inside the nozzle seat 21, ensuring that the baffle 221 is always at the top of the nozzle seat 21 to prevent the entire flow control plug 22 from falling into the water flow channel; the diverter plug 222 is inserted into the water flow channel inside the nozzle seat 21 and extends downward, and the expanded part at the lower end is stuck by the bottom end of the water flow channel inside the nozzle seat 21 and is difficult to be pulled upward. The diverter plug 222 is inserted into the water flow channel to adjust the water output, and at the same time, the expanded part is used to resist the bottom end of the water flow channel to prevent the diverter plug 222 from being washed out by the water flow; the diameter of the diverter plug 222 is smaller than the diameter of the water flow channel inside the nozzle seat 21. The diameter of the diverter plug 222 is slightly smaller to allow water to pass through, avoiding completely blocking the water flow channel;

[0036] The nozzle cap 3 is sleeved on the outside of the nozzle and threadedly connected thereto, and the degree of compression of the nozzle cap 3 on the flow control plug 22 is adjusted by threaded connection, thereby controlling the water spraying amount of the entire nozzle and realizing the opening and closing of the nozzle; a water spray hole 31 is provided on the nozzle cap 3, and atomized water is sprayed out through the water spray hole 31 to realize irrigation.

[0037] In one embodiment of the present application, the quick-plug connector 1 includes a connector 11, a sealing gasket 12, a retaining ring 13, a ferrule 14, and a cap 15. A cavity 111 is provided in the connector 11, and a connecting groove is provided in the cavity 111. The sealing gasket 12, the retaining ring 13, and the ferrule 14 are sequentially placed in the cavity 111 of the connector 11. A connecting groove corresponding to the connecting groove is provided on the cap 15. The cap 15 passes through the ferrule 14, the retaining ring 13, and the sealing gasket 12 in sequence, and is buckled with the connecting groove in the cavity 111. The cap 15 and the connector 11 constitute a detachable structure, and a quick interface 16 is provided at the bottom of the quick-plug connector 1.

[0038] The water inlet pipe is inserted from the quick connection port 16 at the bottom of the quick-connect plug. Since a sealing gasket 12, a retaining spring 13, a ferrule 14 and a cap 15 are arranged inside the connector 11 of the quick-connect plug, when the water inlet pipe is inserted, the retaining spring 13 is pushed upward, and the water inlet pipe passes through the cap 15, the ferrule 14, the retaining spring 13 and the sealing gasket 12. At the same time, the water inlet pipe is fixed due to the force of the retaining spring 13, and it can no longer detach itself from the connection with the quick-connect connector 1.

[0039] When the water inlet pipe needs to be disconnected from the quick-connect connector 1 , the cap 15 is pressed upwards, and the clamping spring 13 receives the force transmitted by the cap 15 to release the fixation of the water inlet pipe, and the water inlet pipe can be drawn out of the quick-connect connector 1 .

[0040] Preferably, a detachable joint 17 threadedly connected to the adjustable nozzle 2 is provided at the top of the connecting head 11, and is threadedly connected to the lower end of the nozzle seat 21 through the detachable joint 17, which is convenient for quick connection between the two and also convenient for disassembly, maintenance and replacement of parts; a detachable sealing rubber ring 18 is provided on the detachable joint 17, and the sealing rubber ring 18 increases the sealing performance between the detachable joint 17 and the nozzle seat 21 to prevent water leakage after the two are connected.

[0041] In one embodiment of the present application, the water flow will be blocked when it hits the diverter plug 222. Therefore, in order to allow more water to be ejected, a diverter channel 2221 is provided in the middle of the diverter plug 222, so that the water flow can enter the diverter channel 2221 after hitting the diverter plug 222. The diverter channel 2221 extends all the way to a position close to the baffle 221. After the water in the diverter channel 2221 reaches the end of the diverter channel 2221, it is ejected from the gap between the diverter plug 222 and the water flow channel. The water channel 2221 evenly divides the diverter plug 222 into three plugs 2222, and an expansion head 2223 is provided at the end of each plug 2222. The expansion head 2223 allows the lower end of the diverter plug 222 to press against the bottom end of the water flow channel to prevent the diverter plug 222 from being washed out of the water flow channel by the water flow. At the same time, since the diverter plug 222 is provided with a diverter water channel 2221, each plug 2222 can be squeezed and bent, thereby facilitating the entire diverter plug 222 to be inserted into the water flow channel and to be pulled out by force.

[0042] In one embodiment of the present application, after the water flows into the water flow channel, in order to facilitate its discharge, the length of the diverter plug 222 is made greater than the length of the water flow channel inside the nozzle seat 21 and a certain distance is left between the top of the expansion head 2223 and the bottom end of the water flow channel inside the nozzle seat 21. The existence of this distance allows the bottom of the baffle 221 and the top of the nozzle seat 21 to be separated under the impact of the water flow, thereby allowing the water in the water flow channel to be quickly sprayed out.

[0043] Preferably, the diverter plug 222 is covered with a gasket 223, which is located between the nozzle seat 21 and the baffle 221. After the nozzle cap 3 is tightened, the gasket 223 achieves close contact between the nozzle seat 21 and the baffle 221 to ensure that the nozzle no longer leaks water after closing.

[0044] In one embodiment of the present application, in order to enhance the atomization effect of the nozzle, an atomization groove 2211 is arranged on the top of the baffle 221, and a water inlet groove 2212 is arranged on the edge of the atomization groove 2211. The water sprayed out of the water flow channel enters the atomization groove 2211 from the water inlet groove 2212, and is squeezed, blocked, and reversed multiple times to make the water flow speed faster and have an atomized form. After entering the atomization groove 2211, the water is sprayed out from the water spray hole 31 of the nozzle cap 3.

[0045] Preferably, two water inlet grooves 2212 are provided and are centrally symmetrically arranged.

[0046] In one embodiment of the present application, a detachable sealing rubber ring 23 is provided on the nozzle seat 21, and the sealing ring is used to enhance the sealing effect between the nozzle seat 21 and the nozzle cap 3 to avoid water leakage from the connection between the two.

[0047] In one embodiment of the present application, since the entire spray head adopts multiple components, in order to facilitate the installation of the various components and facilitate the adjustment of the water flow intensity, anti-slip grooves 4 are provided on the outer walls of the nozzle seat 21 and the nozzle cap 3. By increasing the friction, the convenience of relative rotation operation between the various components is improved.

[0048] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
