The valve cavity 56 is provided with a pause water inlet 84 and a pause water outlet 85 which are communicated with the front and rear water inlet channels 110; one end of the spring 52 is sleeved on the convex column at the top of the valve cavity 56, and the other end is arranged in the groove at the bottom of the button shaft 54; the rubber water-proof block 53 is slidably arranged in the valve sleeve 51 and sleeved at the lower end of the button shaft 54, when the spring 52 is not compressed, the rubber water-proof block 53 is far away from the pause water inlet 84 and the pause water outlet 85, and the water inlet channel 110 is communicated; when the spring 52 is compressed, the rubber water-proof block 53 simultaneously seals the water pause inlet 84 and the water pause outlet 85, and the water inlet channel 110 is closed; the button 55 is arranged at one end of the button shaft 54 far from the rubber water-proof block 53.

Meanwhile, the water pause device 50 is also a reset device, when the button 55 is pressed, the spring 52 is compressed, the rubber water-proof block 53 simultaneously seals the water pause inlet 84 and the water pause outlet 85, and the water inlet channel 110 is closed. Because no water flow acts, the switching spring 21 is kept in an uncompressed state, the sealing rubber ring 221 blocks the second flow passage 72, and the water outlet state of the water outlet device is changed into water outlet from the first flow passage 71.

As shown in fig. 17, when the pressing housing 224 is not pressed, the passage between the water inlet passage 110 and the first flow passage 71 is blocked by the sealing rubber ring 221 by the force of the switching spring 21, the water inlet passage 110 communicates with the second flow passage 72, and water flows out from the water inlet passage 110 along the second flow passage 72.

As shown in fig. 20, when the pressing housing 224 is pressed, the switching spring 21 is compressed, the passage between the water inlet passage 110 and the second flow passage 72 is blocked by the sealing rubber ring 221, the water inlet passage 110 communicates with the first flow passage 71, and water flows out from the water inlet passage 110 along the water spray passage 90 of the first flow passage 71. The switching spring 21 remains compressed due to the water flow.

As shown in fig. 21 and 22, at this time, the finger presses and presses the hemispherical depression 226 of the pressing housing 224 and rotates, the adjusting circular truncated cone 32 of the flow rate adjusting member 30 rotates, the contact area between the non-notch 31 part of the adjusting circular truncated cone 32 and the first water outlet 83 is increased as the gap between the notch 31 and the first water outlet 83 is gradually reduced, the opening area of the first water outlet 83 is reduced, and the water output of the water spraying channel 90 is reduced.

When the pressing shell 224 is rotated left and right to the limit state, the gap between the corresponding notch 31 and the first water outlet 83 is the largest and the gap is the smallest, that is, the water outlet amount of the water spraying channel 90 is the largest and the water outlet amount is the smallest.

To sum up, the utility model provides a pair of flow regulation device, switch the carriage release lever of different water flow ways including reciprocating motion, the circumference of carriage release lever is upwards extended the protrusion and is equipped with flow control spare, the carriage release lever rotates and drives flow control spare and rotates the flow of adjusting the water flow way. When the water outlet device is used, the movable rod is pressed, so that the switching of the water channel is controlled, and a user can select a water outlet position according to the requirement, such as upper water outlet and lower water outlet. Meanwhile, the water outlet quantity of a certain water outlet can be freely selected by rotating the flow regulating piece, and the water outlet size is convenient for a user to wash in daily life.

The above mentioned is only the embodiment of the present invention, and not the limitation of the patent scope of the present invention, all the equivalent transformations made by the contents of the specification and the drawings, or the direct or indirect application in the related technical field, are included in the patent protection scope of the present invention.
