[0038] Thirdly, by setting the fixed magnets into three layers and the through holes into three layers respectively, when the through holes are closed, the fixed magnets and the through holes are sealed at different planes respectively, forming a multi-plane sealing structure, increasing the hierarchy and redundancy of the seal, and ensuring that when the seal of any layer of the fixed magnets fails, there are still other fixed magnets to maintain the sealing state. The sealing durability of the faucet in the closed state is further improved, and the excellent sealing performance can be maintained even under extreme conditions of use.

[0039] Fourthly, by adding an elastic portion made of rubber between the fixed magnet and the through hole, an additional elastic sealing layer can be provided on the basis of the fixed magnet sealing, thereby further improving the sealing effect.

[0040] Fifth, by adopting an annular airbag, connected to the outside of the shell through an air guide tube, and providing a valve core at the outer end, under a high-pressure environment, more gas can be filled into the annular airbag to increase the pressure to compensate for the influence of the high pressure, thereby ensuring the sealing effect of the faucet under a high-pressure environment.

[0041] Sixthly, by adding iron powder into the annular airbag, when the through hole is closed, the iron powder is attracted to the fixed magnet by magnetic attraction, thereby making the annular airbag and the fixed magnet fit more closely, thereby improving the sealing effect.

[0058] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which the present invention belongs; the terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more related listed items.

[0059] Embodiment 1: Figure 1-Figure 4 As shown, the unsaturated polyester resin faucet of the present application includes a water inlet pipe 100, a water outlet pipe 200 and a water control device 300;

[0060] The water control device 300 is used to connect the water inlet pipe 100 and the water outlet pipe 200, and the water control device 300 includes a housing 310;

[0061] The shell 310 is cylindrical, and two shells 310 are provided. The shells 310 are connected to the water inlet pipe 100 and the water outlet pipe 200 respectively. The shell 310 is used to control the waterway. The shell 310 includes a cavity 340, a telescopic groove 350 and a water cavity 360. The shell 310 is made of unsaturated polyester resin.

[0062] The cavity 340 is disposed in the middle of the housing 310 , and is cylindrical in shape. The cavity 340 is connected to the water inlet pipe 100 ;

[0063] The telescopic slots 350 are cylindrical, and are evenly distributed on the outside of the cavity 340 in the circumferential direction. The number of the telescopic slots 350 is an even number, and there are at least four telescopic slots 350. A valve hole 341 is provided between the telescopic slot 350 and the cavity 340, and the valve hole 341 is used to connect the cavity 340 and the telescopic slot 350. The telescopic slot 350 includes a fixed magnet 351 sliding inside the telescopic slot 350.

[0064] The fixed magnet 351 is cylindrical, and the outer diameter of the fixed magnet 351 is the same as the inner diameter of the telescopic slot 350. The fixed magnet 351 is elastically connected to the telescopic slot 350. The number of the fixed magnets 351 is the same as the telescopic slot 350. The fixed magnets 351 are divided into group a and group b along a diameter of the cavity 340. The number of the fixed magnets 351 in group a and group b is the same. Group a contains at least two fixed magnets 351. The magnetic poles of the fixed magnets 351 in group a are the same, and the magnetic poles of the fixed magnets 351 in group b are opposite to those of the fixed magnets 351 in group a.

[0065] The water cavity 360 is cylindrical, and a through hole 361 is defined between the water cavity 360 and the telescopic slot 350 . The through hole 361 is used to connect the telescopic slot 350 and the water cavity 360 .

[0066] Furthermore, the water control device 300 also includes a connecting pipe 320 and an adjustment ring 330;

[0067] The connecting pipe 320 is disposed between the two shells 310 , and the connecting pipe 320 is connected to the water cavity 360 . The connecting pipe 320 is used to connect the waterway;

[0068] The adjusting ring 330 is rotatably sleeved on the outside of the connecting pipe 320, and the adjusting ring 330 is used to rotate to adjust the water output, and the adjusting ring 330 also includes a moving magnet 331;

[0069] The number of the moving magnets 331 is the same as the number of the fixed magnets 351. The moving magnets 331 are located on the axis of the fixed magnets 351. The moving magnets 331 and the fixed magnets 351 have opposite magnetic poles on opposite surfaces. The moving magnets 331 are used to generate magnetic attraction or magnetic repulsion to adjust the position of the fixed magnets 351 in the telescopic slot 350 when the adjustment ring 330 rotates, so that the fixed magnets 351 block the valve hole 341 and the through hole 361 to cut off the water flow or open the valve hole 341 and the through hole 361 to conduct the water flow.

[0070] When an unsaturated polyester resin faucet according to an embodiment of the present application is actually operated, the steps are as follows:

[0071] The water inlet pipe 100 is connected to the water supply pipe, and water enters the cavity 340 inside the water control device 300. When the relative magnetic poles of the moving magnet 331 and the fixed magnet 351 are opposite, the elastic force of the spring and the magnetic attraction provided by the moving magnet 331 make the fixed magnet 351 close to the through hole 361, thereby blocking the valve hole 341 and the through hole 361, and the water path is disconnected. The device is in a closed state. When water is needed, the adjusting ring 330 is rotated to make the relative magnetic poles of the moving magnet 331 and the fixed magnet 351 the same. The fixed magnet 351 overcomes the elastic force of the spring under the action of magnetic repulsion and moves in the telescopic groove 350, and the through hole 361 and the valve hole 341 are opened. The water in the cavity 340 flows through the telescopic groove 350 and the water cavity 360 and is introduced into the connecting pipe 320 for discharge.

[0072] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0073] The position of the moving magnet 331 is controlled by rotating the adjustment ring 330, so that the moving magnet 331 and the fixed magnet 351 are attracted or repelled, so that the moving magnet 331 is moved to open the water path by the repulsive force to overcome the spring force, or is moved to close the pipeline by the spring force and magnetic attraction, thereby realizing the switch control of the water path. Especially after long-term use, the spring force decays, but there is still magnetic attraction to ensure the sealing effect when closing, ensuring that water leakage can be effectively reduced under various conditions of use and maximizing the utilization of water resources. In addition, by providing multiple fixed magnets 351 in each group, when the adjustment ring 330 is rotated, each time the angle of an adjacent fixed magnet 351 is rotated, only a pair of through holes 361 at symmetrical positions will be opened or closed, so that the water output can be adjusted in stages, and then the water output can be controlled according to the use conditions to reduce the waste of water resources.

[0074] Embodiment 2: Considering that when the fixed magnet 351 closes the through hole 361, the shell 310 at the edge of the through hole 361 will brake the fixed magnet 351 moving under the action of elastic force and magnetic attraction, which may easily cause damage to the fixed magnet 351 and reduce the sealing effect under long-term repeated conditions; the embodiment of the present application is optimized based on the above embodiment.

[0075] like Figure 5 As shown, a silicon nitride ceramic coating is fixed on the outside of one end of the fixed magnet 351 close to the through hole 361 . The silicon nitride ceramic coating is configured in a cone shape and is used to prevent the fixed magnet 351 from being worn.

[0076] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0077] By fixing a conical silicon nitride ceramic coating on one end of the fixed magnet 351 close to the through hole 361, when the fixed magnet 351 closes the through hole 361, the silicon nitride ceramic coating collides with the through hole 361, thereby reducing the wear of the fixed magnet 351 and improving the durability of the seal. At the same time, the silicon nitride ceramic coating is conical, which further reduces the collision area and extends the service life, thereby making the sealing performance more durable and reliable.

[0078] Embodiment 3: Considering that although the conical silicon nitride ceramic has excellent wear resistance, it may still fail to completely seal the through hole 361 after long-term use due to factors such as manufacturing process, installation error and use environment; the embodiment of the present application is optimized based on the above embodiment.

[0079] like Figure 6-Figure 8 As shown, the fixed magnet 351 includes a supporting portion 3511, a main shaft portion 3512, an inner ring portion 3513 and an outer ring portion 3514;

The inner ring portion 3513 is slidably connected to the main shaft portion 3512, and the inner ring portion 3513 is elastically connected to the support portion 3511. The inner ring portion 3513 is made of an iron-nickel alloy.

[0083] The outer ring portion 3514 is annular and tubular, and the inner diameter of the outer ring portion 3514 is the same as the outer diameter of the inner ring portion 3513. The outer ring portion 3514 is slidably connected to the inner ring portion 3513, and the outer ring portion 3514 is elastically connected to the support portion 3511. The outer ring portion 3514 is made of iron-nickel alloy.

[0084] Furthermore, the through hole 361 includes an upper hole 3611, a middle hole 3612 and a lower hole 3613;

[0085] The upper hole 3611 is cylindrical, and the upper hole 3611 is axially colinear with the main shaft portion 3512. The upper hole 3611 is arranged on a side of the through hole 361 close to the water cavity 360. The inner diameter of the upper hole 3611 is half of the outer diameter of the main shaft portion 3512. The upper hole 3611 is used to contact with the main shaft portion 3512 to form a first layer of sealing;

[0086] The middle hole 3612 is cylindrical, and the middle hole 3612 and the upper hole 3611 are axially colinear. The middle hole 3612 is arranged in the middle of the through hole 361. The inner diameter of the middle hole 3612 is half of the sum of the inner diameter and the outer diameter of the inner ring portion 3513. The middle hole 3612 is used to contact with the inner ring portion 3513 to form a second layer of sealing;

[0087] The lower hole 3613 is cylindrical and is axially colinear with the middle hole 3612. The lower hole 3613 is arranged on the side of the through hole 361 close to the expansion slot 350. The inner diameter of the lower hole 3613 is half of the sum of the inner diameter and the outer diameter of the outer ring part 3514. The lower hole 3613 is used to contact with the outer ring part 3514 to form a third layer of sealing.

[0088] Furthermore, the outer diameter of the outer ring portion 3514 is the same as the inner diameter of the telescopic groove 350 , and the outer ring portion 3514 blocks the valve hole 341 when contacting the lower hole 3613 .

[0089] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0090] By setting the fixed magnet 351 to have three layers, the fixed magnet 351 includes a support seat, a main shaft portion 3512, an inner ring portion 3513 and an outer ring portion 3514, and the through hole 361 is correspondingly provided with three layers, corresponding to the main shaft portion 3512, the inner ring portion 3513 and the outer ring portion 3514 respectively. When the through hole 361 is closed, the main shaft portion 3512, the inner ring portion 3513 and the outer ring portion 3514 are respectively sealed at different planes to form a multi-plane sealing structure, which increases the hierarchy and redundancy of the seal, and ensures that when the seal of any layer of the fixed magnet 351 fails, there are still other fixed magnets 351 to maintain the sealing state. The sealing durability of the faucet in the closed state is further improved, and the excellent sealing performance can be maintained even under extreme conditions of use.

[0091] Embodiment 4: Considering that the edge of the through hole 361 may wear in certain extreme usage scenarios (such as corrosive environments), it is impossible to fit tightly with the sealing end of the fixed magnet 351 to achieve sealing, thereby affecting the sealing effect; the embodiment of the present application is optimized based on the above embodiment.

[0092] like Figure 9-10 As shown, the water cavity 360 further includes an elastic portion 362 , which is disposed inside the through hole 361 . The elastic portion 362 is used for deforming to adapt to the surface of the fixed magnet 351 to enhance the sealing effect, and the elastic portion 362 is made of rubber.

[0093] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0094] By adding an elastic portion 362 made of rubber between the fixed magnet 351 and the through hole 361 , an additional elastic sealing layer can be provided on the basis of the sealing of the fixed magnet 351 , thereby further improving the sealing effect.

[0095] Embodiment 5: Considering that under certain extreme conditions of high temperature and high pressure, the elastic part 362 is squeezed by water pressure, and the elastic force of the elastic part 362 itself is not enough to overcome the water pressure and squeeze the edge of the sealing end, resulting in a decrease in the sealing effect; the embodiment of the present application is optimized based on the above embodiment.

[0096] like Figure 11-Figure 12 As shown, the elastic portion 362 includes an annular airbag 3621;

[0097] The annular airbag 3621 is fixed to the inner side of the through hole 361 , and the annular airbag 3621 is used to change the internal air volume and thus the air pressure to adapt to different water pressure environments.
