Embodiment 1

Referring to FIGS. 1-11, this embodiment provides a telescopic aerator, which comprises: an aerator body 1, a telescopic assembly 2 and a mounting seat 3; the telescopic assembly 2 is swingably connected to the aerator body 1 through a ball head 4; the telescopic assembly 2 drives the aerator body 1 to move to a first position or a second position along an axial direction of the mounting seat 3 under water pressure changes when the water stops and the water flows; when the aerator body 1 is in the first position, the aerator body 1 abuts the mounting seat 3, and in this embodiment, a fixed ring connected to the ball head 4 is accommodated in the mounting seat 3 synchronously; and when the aerator body 1 is in the second position, the aerator body 1 is separated from the mounting seat 3 by a preset distance, and the fixed ring 11 connected to the aerator body 1 and the ball head 4 is exposed outside of the mounting seat 3 synchronously. In this embodiment, the aerator body 1 is driven to move by the water pressure changes when the water stops and the water flows. As a simple alternative, an electrical signal can be generated by water flow changes when the water stops and the water flows, and a controller controls an electromagnetic unit or a mechanical unit to drive the aerator body 1 to move using electromagnetic force or mechanical force through the electrical signal.
The aforementioned aerator allows a piston component to drive the aerator body 1 to move between the first position and the second position through the water pressure changes when the water stops the and the water flows, consequently, when the water flows, the aerator body 1 is separated from the mounting seat 3 by the preset distance, so that the aerator body 1 can swing to adjust an angle of water outflow; and when the water stops, the aerator body 1 abuts the mounting seat 3, ensuring consistency in an appearance of the aerator in a water stop state.
In order to enable the aerator body 1 to be guided and restored to be centered when the water stops, the mounting seat 3 and the aerator body comprise a guiding wall 31 configured for a guiding cooperation with the fixed ring 11 within in the first position. Specifically, the guiding wall 31 surrounds to define a receiving chamber 32 with an opening at two ends, and the receiving chamber 32 has a structure with a diameter of the opening that gradually increases from one end away from the aerator body 1 to the other end. In this way, the aerator body 1 will accurately restored to the second position through a guiding effect of the guiding wall 31 during a movement.
In order to be achieve the guiding cooperation with the guiding wall 31, the fixed ring 11 has an inclined surface that fits the guiding wall 31.
In addition, in order to ensure normal water outflow function of the aerator, the telescopic assembly 2 and the ball head 4 comprise a water flow passage 5 for water passage. In this way, water can flow into the aerator body 1 from the water flow passage.

In this way, when the telescopic assembly 2 drives an aerator assembly to the first position, the spring 22 is in a relatively loose state. When the telescopic assembly 2 drives the aerator body 1 to the second position, the spring 22 is in a compressed state. At this time, if a water flowing state is converted to the water stop state, the water pressure applied to the piston 21 becomes smaller, and the spring 22 releases an elastic restoring force to drive the aerator body 1 to be restored to the first position.
In this embodiment, the mounting seat 3 comprises a through passage for the piston 21 to pass through, the through passage comprises a side wall 35 extending upward along a direction of the water flow, and in this embodiment, the side wall 35 further comprises the guiding wall 31 disposed on a lower end of the side wall 35 and stretching outward along a radial direction; the mounting seat 3 further comprises an outer peripheral wall 32 configured for connecting to a water outlet device; and the outer peripheral wall 32 comprises a thread. The outer peripheral wall 32 is connected to a bottom of the guiding wall 31 through a bottom wall 34, so that a first groove 33 with an opening facing upward is formed between the outer peripheral wall 32 and the guiding wall 31, and the spring 22 abuts the bottom wall 34; and the piston 21 comprises a sealing portion 211 hermetically sealed to the mounting seat 3 and a connecting portion 212 connected to the ball head 4, and a second groove 213 with an opening facing downward is formed between the sealing portion 211 and the connecting portion 212. Consequently, when the aerator body 1 is in the second position, the side wall 35 of the through passage is inserted into the second groove 213 through the opening. The sealing portion 211 comprises a groove disposed on an outer peripheral wall of the piston and a Y-shaped ring 23 installed in the groove.

Therefore, the shell 16 rotates to drive the water dividing body 15 and the water inlet seat 12 to rotate relative to the sealing gasket 14.
The sealing gasket 14 is disposed between the pressure cover 13 and the water dividing body 15, and a downward-pressing spring 17 is disposed on a side of the pressure cover 13 away from the sealing gasket 14, and one end of the spring away from the pressure cover 13 abuts the water inlet seat 12. The water inlet seat 12 squeezes the downward-pressing spring 17 during a movement from a first position to a second position, so that the downward-pressing spring 17 drives the pressure cover 13 to downwardly press down the sealing gasket 14.
The pressure cover 13 further comprises an annular water passage opening 132 on an outer side of the avoidance opening 131 along a radial direction. The water dividing body 15 comprises a first flow passage 151 and second flow passages 152, the second flow passages 152 are disposed at intervals along a circumferential direction, and the first flow passage 151 is disposed between two adjacent ones of the second flow passages 152. The first flow passage 151 and the second flow passages 152 are separated by a baffle 153. The water passage opening 132 is in communication with the first flow passage 151 and the second flow passages 152 simultaneously.
When the water inlet seat 12 is in the first position, the downward-pressing spring 17 is in an extended state, a communication between the water passage opening 132 and the second flow passages 152 is opened using the sealing gasket 14, the water flow respectively flows out through the first flow passage 151 and the second flow passages 152 of the water dividing body 15, an outer annular water spray wraps an inner annular water spray to finally form a beam of the water flow at a water outlet nozzle of the aerator body 1, as inner and outer rings are filled with the water flow, external air cannot be inhaled into a cavity of the aerator body 1, water spray in a soft water state is formed.
When the shell 16 drives the water inlet seat 12 to rotate to the second position, the downward-pressing spring 17 is in a compressed state, and the sealing gasket 14 is squeezed by the pressure cover 13, thereby sealing the communication between the water passage opening 132 and the second flow passages 152. The second flow passages 152 of the water dividing body 15 are sealed, and the water flows out of the first flow passage 151. A steel sheet 154 is disposed on a water outlet of the first flow passage 151, and the water flows through fine holes on the steel sheet 154 to form multiple beams of delicate steel sheet water sprays.
