The first nozzle housing front part 111 and the first nozzle housing rear part 113 are correspondingly spliced, the inner cavities of the first nozzle housing front part 111 and the first nozzle housing rear part 113 are used for accommodating the rotary water outlet component 16 and the sounding component 17, the second nozzle housing front part 112 and the second nozzle housing rear part 114 are correspondingly spliced, and the inner cavities of the second nozzle housing front part 112 and the second nozzle housing rear part 114 are used for accommodating the gear box, the upper chain handle 13, the gear box switch, the rotary output component 15 and the unidirectional stop component 18.

The gear case 12 includes an integral input/output shaft 121 and a synchronous rotating member 122 provided on a surface, the synchronous rotating member 122 rotating in synchronization with the input/output shaft 121. The gear box is a common up-chain gear box in the market, and is also commonly called as a up-chain gear box, the working principle of the gear box is that the up-chain handle 13 is twisted, rotary motion is input into the gear box through an input shaft, so that a spring in the gear box tightens up and stores force, and the output shaft is driven to rotate by restoring force of the spring after the up-chain handle 13 is released. The gearbox may employ separate input and output shafts or may employ an integral input/output shaft 121, the latter being preferred in this embodiment. The specific internal structure of the gearbox is not described here in detail.

The first end of the upper chain handle 13 extends out of the front part 112 of the second nozzle housing through the upper chain hole 1121, the second end of the upper chain handle 13 is fixedly sleeved on the input/output shaft 121, a one-way clutch button 131 is sleeved outside the second end of the upper chain handle 13, and the rotary output part 15 is sleeved on the one-way clutch button 131; the rotary output member 15 is a gear, an inner circumferential surface of which is provided with an inner gear ring 151 engaged with the one-way clutch button 131, and an outer circumferential surface of which is provided with an outer gear ring 152 engaged with the rotary water outlet member 16; when the rotating handle rotates along the uplink direction of the gear box, the input/output shaft 121 rotates synchronously, the one-way clutch button 131 idles in the inner gear ring 151 of the rotating output member 15, and the rotating output member 15 does not rotate synchronously; when the input/output shaft 121 rotates in the releasing direction of the gear box, the one-way clutch button 131 engages with the ring gear 151 of the rotary output member 15, and drives the rotary output member 15 to rotate. In other embodiments, independent rotation between the winding handle and the rotary output member may be achieved in other ways than a one-way clutch.

The gearbox of the invention can adopt a gearbox without a switch (correspondingly, the gearbox does not need to be provided with a synchronous rotating component), the gearbox is released immediately after being uplinked, in the embodiment, the gearbox with a gearbox switch is preferably adopted, the gearbox can be controlled to keep the power storage after being uplinked and not released immediately, and the release of the gearbox is controlled through the gearbox switch, so that the rotation of the spray head is controlled. The gear box switch may specifically be an external switch or an internal switch, or the external switch and the internal switch are adopted simultaneously, in this embodiment, the external switch 141 and the internal switch 142 are preferably adopted simultaneously, when one of the external switch and the internal switch is located at an on position, the spray head is operated (i.e. the rotary output part 15 and the rotary water outlet part 16 rotate), and the external switch and the internal switch are both located at an off position, so that the spray head is not operated (i.e. the rotary output part 15 and the rotary water outlet part 16 are stationary). The external switch 141 is directly used for a user to toggle to control whether the gear box works, and the internal switch 142 is used for controlling whether the gear box works through the trigger of the user by being linked with the trigger.

When the external switch and the internal switch enter the closed position, the gear box switch stops applying force to the vertical piece 181, the first spring 183 resets, the vertical piece 181 moves towards the gear box under the force of the first spring 183 until the transverse piece 182 contacts with the synchronous rotating component 122, the transverse piece 182 carries out unidirectional stop on the synchronous rotating component 122, so that the synchronous rotating component 122 cannot rotate along the releasing direction of the gear box, and the input/output shaft 121 cannot carry out output rotation; when the external switch and the internal switch are at the closed positions, the transverse plate 182 only performs unidirectional stop on the synchronous rotation part 122, and allows the synchronous rotation part 122 to rotate along the other direction, specifically, the synchronous rotation part 122 can rotate along the uplink direction of the gear box, the transverse plate 182 and the vertical plate 181 are pushed to move so as to complete the rotation, and the acting force of the first spring 183 keeps the transverse plate 182 in contact with the synchronous rotation part 122, so that the synchronous rotation part 122 can still rotate along the uplink direction of the gear box, and the input/output shaft 121 can still perform input rotation. In other embodiments, the one-way stop member may take other shapes and configurations, and the first spring may be disposed between the vertical tab and the outer wall of the gearbox.

To achieve a one-way stop, the transverse tab 182 is configured to mate with the shape of the synchronous turning member 122 such that the transverse tab 182 can unidirectionally retain the synchronous turning member 122, but at the same time allow it to rotate in the other direction.

In other embodiments, the external switch may take other shapes and configurations.

The structure and working principle of the built-in switch 142 are as follows: the built-in switch is in a thin strip structure, and is fixedly connected with the vertical piece 181, a built-in switch hole 1141 is formed in the front surface of the rear part 114 of the second nozzle housing, the built-in switch can move in the built-in switch hole 1141, and when the built-in switch is forced to move towards the direction of the inner side wall of the rear part 114 of the second nozzle housing, the vertical piece 181 is driven to synchronously move, so that the transverse piece 182 is separated from the synchronous rotating part 122; when the built-in switch is not stressed, the first spring 183 resets, and drives the vertical piece 181 and the built-in switch to move towards the direction of the gear box, so that the transverse piece 182 contacts with the synchronous rotating component 122. In other embodiments, the built-in switch may take other shapes and configurations.
