The utility model discloses a trinity shower nozzle, at the during operation, water is carried to the play water hole of quick-witted bayonet joint earlier through the barrel, and the apopore is the inclined hole, and water is selected to the intervalve position through the inclined hole, has three holes on the intervalve, corresponds high-pressure straight line nozzle, high-pressure fan nozzle and low-pressure hole respectively. When one of the two high-pressure nozzles is used, the rotating sleeve is rotated by hand and moves together with the middle disc, three grooves are formed in the rotating sleeve, when the functional position is reached, the sharp corners at the front ends of the ratchets are flicked into the grooves under the action of the springs to give a crisp 'click' sound to remind a user that the spray head reaches the correct use position, the function name of a product at the current position can be engraved on the rotating sleeve, an operator can confirm whether the function is required by the operator at present, the rotating or gun-opening use is continued according to the actual situation, and when the position is at the specified correct position, water is ensured to only come out of the holes to form a high-pressure straight line or a high-pressure fan shape. When the low-pressure hole is used, the cleaning machine rotates to a specified position, and due to the siphon of the cleaning machine, the soap liquid in the kettle carried by the cleaning machine is sucked, and a little foam is generated when the low-pressure hole comes out, so that the cleaning effect is improved. And in order to prevent the influence of the internal overstock on the service life of the spray head, because the low-pressure hole is not limited by a sealing ring, when the use error of an operator occurs, the rotary sleeve is not rotated to the appointed position with three functions, the gun is opened for use, water flows out from the low-pressure hole, the internal pressure is reduced, and the pressure relief protection effect is realized.

The utility model discloses a trinity shower nozzle, rotatory sheathe in and set up the slot, the quick connector of pegging graft is last to set up the caulking groove, the slot is corresponding with the caulking groove to it is spacing mutually by U type round pin, U type round pin is square, the contact surface is wide, more firm. The middle disc is in fit contact with the zero clearance surface of the quick connector, and the sealing performance is good. The high-pressure linear nozzle and the high-pressure fan-shaped nozzle are respectively provided with the high-hardness O-shaped rings, so that the nozzles are ensured to be watertight and have long service life. A first sealing ring is arranged between the quick connector and the rotary sleeve. And a second sealing ring is arranged between the quick connector and the middle disc. And a third sealing ring is arranged between the rotary sleeve and the middle disc. And a fourth sealing ring is arranged at the tail part of the quick connector. Sealing rings are arranged among all the parts, so that the parts are ensured to be watertight.

Detailed Description

The utility model relates to a trinity shower nozzle, as shown in fig. 1-4, including a quick connector 1, the swivel mount 2 is established to quick connector overcoat, and the system has apopore 3 in the quick connector, sets up ratchet 4 and spring 5 on the quick connector, sets up intermediate disk 6 between quick connector 1 and swivel mount 2, intermediate disk 6 is connected on swivel mount 2, and the system has three holes in the intermediate disk, sets up high-pressure straight line nozzle 7 in one of them hole, sets up high-pressure fan nozzle 8 in another hole, and last hole site low pressure hole 9, high-pressure fan nozzle 8 and high-pressure straight line nozzle 7 cooperate with apopore 3 respectively, 2 inside three recesses 10 that set up of swivel mount, three recess cooperate with the front end angle of ratchet respectively. During operation, water is conveyed into the water outlet hole 3 of the quick connector 1 through the gun barrel, the water outlet hole is an inclined hole, the water is selected from the position of the intermediate disc 6 through the inclined hole, and the intermediate disc 6 is provided with three holes which respectively correspond to the high-pressure linear nozzle 7, the high-pressure fan-shaped nozzle 8 and the low-pressure hole 9. When one of the two high-pressure nozzles is used, the rotary sleeve 2 is rotated by hand, the middle disc 6 moves, the three grooves 10 are formed in the rotary sleeve 2, when the functional position is reached, the sharp corners at the front ends of the ratchets 4 are flicked into the grooves 10 under the action of the springs 5 by the ratchets 4, a crisp 'click' sound is emitted to remind a user that the spray head reaches the correct use position, the function name of a product at the current position can be engraved on the rotary sleeve 2, the operator can confirm whether the function is required by the operator at present, the operator can continue to rotate or use the spray gun according to actual conditions, and when the position is at the specified correct position, water can only come out of the hole to form a high-pressure straight line or a high-pressure fan shape.
