The limiting groove 263 is internally connected with a plurality of second springs 264, the plurality of second springs 264 are uniformly distributed on the limiting groove 263 along the circumferential direction of the limiting groove 263, the second springs 264 are positioned above the limiting block 262, two ends of the second springs 264 are respectively abutted on the top wall of the limiting groove 263 and the top surface of the limiting block 262, and the second springs 264 are always in a compression state. When the pressure of the outside is almost the same as that of the water storage cavity 11, the limiting block 262 moves to abut against the bottom wall of the limiting groove 263 under the action of the second springs 264, and when the pumping device 23 pumps air into the water storage cavity 11, the air pressure in the water storage cavity 11 will gradually increase, so as to drive the limiting block 262 and the slider 261 to move upward.

Referring to fig. 7 and 8, the top end of the slider 261 extends out of the end cap 2 and is marked with graduation marks. The position of the sliding block 261 on the sliding groove 26 is controlled by the air pressure difference between the outside and the water storage cavity 11, and an operator can judge the current pressure in the water storage cavity 11 by directly observing the scale marks on the end part of the sliding block 261 sliding out of the end cover 2, so as to deduce the amount of water sprayed by the existing sprayer.

Referring to fig. 7 and 8, a first plate 27 is connected to the end cap 2 in a sliding manner along the horizontal direction, the first plate 27 is located below the manual control plate 24, the water storage cavity 11 is not communicated with the outside when the first plate 27 slides, and the first plate 27 is located on one side of the sliding block 261 close to the handle 22.

Referring to fig. 7 and 8, when the pressure inside the water storage cavity 11 is higher than the external pressure, the air pressure inside the water storage cavity 11 drives the slider 261 to move upward, and the locking block 244 moves to the opening of the movable slot 213, at this time, the second inclined surface 2661 is disposed opposite to the first inclined surface 2721 and is located right above the first inclined surface 2721; as the sprayer continuously sprays water, the air pressure in the water storage cavity 11 gradually decreases until the air pressure approaches the external air pressure, and in the process, the sliding block 261 moves downward under the action of the plurality of second springs 264, the second inclined surface 2661 abuts against the first inclined surface 2721 and drives the first block 272 to slide towards the side far away from the sliding block 261, and the first plate 27 and the linkage piece 25 drive the locking block 244 to move out of the movable groove 213.

Referring to fig. 1 and 9, the sprayer body 1 is connected with the explosion-proof device 12 through threads, and the explosion-proof device 12 includes an explosion-proof block 121, a movable rod 122, a first abutting block 1222, a second abutting block 1221, and a third spring 124. Set up the through-hole 125 that communicates external world and water storage chamber 11 on the explosion-proof piece 121, the movable rod 122 wears to establish the through-hole 125 setting, leaves the gassing clearance between movable rod 122 and the through-hole 125, and first block 1222 of supporting is fixed in the one end that movable rod 122 extended water storage chamber 11, the second is supported the block 1221 and is fixed in the one end that movable rod 122 extended external world, and the both ends of third spring 124 butt respectively on explosion-proof piece 121 towards one side of water storage chamber 11 and on first block 1222 of supporting, and third spring 124 is compression state all the time. When the air pressure in the water storage cavity 11 is at a rated value, the second abutting block 1221 abuts against the explosion-proof block 121 under the action of the third spring 124 and blocks the through hole 125, and the part of the second abutting block 1221, which is in contact with the explosion-proof block 121, is made of a rubber material, so that the air tightness of the water storage cavity 11 can be ensured; when the air pressure in the water storage cavity 11 is higher than the rated value, the air pressure in the water storage cavity 11 pushes the movable rod 122 toward one side of the second abutting block 1221, so that the second abutting block 1221 moves to a position where the through hole 125 is no longer blocked, and at this time, the external air pressure and the air pressure in the water storage cavity 11 can quickly reach a balanced state.

Referring to fig. 1 and 9, in order to facilitate an operator to rapidly control the air pressure in the water storage cavity 11 to be balanced with the outside, a pull ring 123 for applying force by hand is fixed on a side surface of the second abutting block 1221 away from the first abutting block 1222. When water spraying is not required, an operator pulls the pull ring 123 to automatically drive the locking block 244 to move out of the movable groove 213, and water spraying is stopped.

The implementation principle of a manual sprayer in the embodiment of the application is as follows: an operator repeatedly pulls the pressing bar 232 to inflate the water storage cavity 11 and then presses the hand control panel 24, long-time water spraying can be automatically realized, and when the air pressure in the water storage cavity 11 is not enough to spray water, the locking block 244 can be automatically moved out of the movable groove 213 under a series of structures, so that the hand control panel 24 is moved to a state of stopping water spraying.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: equivalent changes in structure, shape and principle of the present application shall be covered by the protection scope of the present application.
