The flow regulator is characterized in that it has a regulator housing configured to be inserted into a cylinder or embedded in a cylinder, and a movably guided adjusting star wheel and a throttling body surrounding the adjusting star wheel are arranged in the inner space of its housing; at least one housing hole configured as a fluid inlet is provided on the housing circumference of the regulator housing; and the lead screw can be manipulated from the housing end face. For example, CN106286871A, a flow regulator, includes: a main body, a normally open flow channel and a throttling part that can be elastically deformed are arranged in the main body; the throttling part cooperates with the normally open flow channel to utilize the characteristics of its own deformation under the action of water pressure to change the water flow area of ​​the normally open flow channel to achieve throttling; and at least one bypass flow channel and an inseparable manual adjustment part; the water flow area of ​​the bypass flow channel is adjusted by the manual adjustment part. It provides a flow regulator, which is provided with a normally open flow channel and a bypass flow channel.

[0052] Please refer to Figures 6 to 9The shower comprises a main body 5 and a temperature control device 4. The main body 5 is provided with a cold water circuit 51, a hot water circuit 52, a mixing water circuit 53 and a two-way water circuit 54. The interface of the cold water circuit 51 and the interface of the hot water circuit 52 are arranged horizontally at intervals along the main body 51, and the interface of the two-way water circuit 54 is located in the middle of the main body 51 and is arranged back to back up and down.

[0053] The temperature control device 4 is installed in the main body 5 and cooperates with the cold water path 51, the hot water path 52 and the mixed water path 53 to adjust the water temperature. The temperature control device 4 can refer to the existing technology. The throttling water path control device A is installed in the main body 5 and the connecting channel of the water inlet path 13 is connected to the mixed water path 53. The two water paths 54 and the two water diversion paths 121 are connected one by one. The temperature control device 4 has a temperature control operating member 41 that can control the temperature control device 4.

[0054] In the throttling waterway control device A of this specific embodiment: please refer to Figure 3 In the water-saving state, the upper ratchet 35 is pressed to overcome the elastic force of the reset spring, and the movable rod 31 is pushed inward (downward in the figure). The sealing part 32 on the movable rod 31 blocks the on-off channel 214 of the water-saving seat 22. At this time, the water flow can only pass through the normally open channel 213 of the water-saving seat 22. The sealing ring 33 set on the normally open channel 213 will automatically adjust the area of ​​the normally open channel 213 to block the normally open channel 213 according to the water pressure. When the water pressure increases, the sealing ring 33 is squeezed by the water pressure, increasing the area of ​​the normally open channel 213 and reducing the water flow area of ​​the normally open channel 213. When the water pressure decreases, the sealing ring is less squeezed by the water pressure, recovers its deformation, and reduces the blocking area, so that the flow rate is constant and is less affected by the water pressure, achieving the effect of water-saving and constant flow. Please refer to Figure 4In the non-water-saving state, the upper ratchet 35 is pressed again, and under the action of the reset spring, the movable rod 31 is driven upward, and the sealing portion 32 of the movable rod 31 is separated from the on-off channel 214 on the water-saving seat 22, and the on-off channel 214 is opened. At this time, water can flow through the on-off channel 214 and the normally open channel 213. In this state, the flow rate is affected by the water pressure. The water pressure is large, the flow rate is large, and there is no water-saving function. Rotate the rotating part 21 to drive the movable plate 24 to rotate. When the movable plate control port and the fixed plate water outlet are not connected, it is in the water-off state.

[0055] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of the present invention.
