Description

Technical Field

[0001] The invention relates to the field of faucets, and more particularly to a multi-stage constant-flow faucet. Background Art

[0002] A multi-level constant-flow faucet is a faucet with special functions that can achieve different levels of water flow control to meet the needs of users in different usage scenarios.

[0003] If you live in a high-rise building or in an area where the water pressure is unstable, the gas in the faucet will be sprayed together with the water under pressure, which may cause the water flow to fluctuate. Aging water pipes or leaks may also cause unstable water pressure, which in turn affects the water output of the faucet. This causes the faucet to produce water mixed with air and gush out from the faucet when in use. This phenomenon is more obvious on multi-stage constant-flow faucets, because most multi-stage constant-flow faucets change the flow rate of the liquid to achieve multi-stage control. This makes it easy for water to spray out at high speed when the pressure is unstable, or it may be unable to flow out due to insufficient water pressure, and the air will be pushed out of the faucet by the pressure, which greatly affects the use. When the air is entrained and sprayed out, it will increase the resistance and friction through the faucet, which will cause damage to internal parts.

[0004] In view of this, and in view of the above-mentioned shortcomings, the present invention produces a multi-stage constant-flow faucet. Summary of the invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. This device is provided with a constant pressure component. When the pressure suddenly increases, the constant pressure component cooperates with the faucet component to prevent the occurrence of water jetting caused by high pressure. When the pressure gradually decreases, the pressure-stabilizing spring returns to a moderate pressure state. When the water flows into the pressure-stabilizing shell, an initial pressure will be generated inside the pressure-stabilizing shell. At this time, if the pipeline pressure drops suddenly, the pressure-stabilizing spring can release part of the pressure, so that the water flow output to the faucet component is relatively stable, and the water flow output from the faucet component will not fluctuate due to changes in pressure, thereby reducing the impact of pressure on the device and making it more comfortable to use.

[0020] 2. By setting up a vent pipe, the device can filter out the air entrained in the water flow in advance to prevent the water flow and gas from being sprayed together during use, thereby improving the stable output of the water flow and the comfort of use.

[0021] 3. This device makes the total amount of water output constant by reducing the flow rate of the liquid. When the water pressure is reduced to a constant water pressure, the secondary spring will push the third pipe again to increase the overlap between the water outlet and the water outlet port to increase the liquid flow rate, thereby preventing the liquid flow rate from fluctuating due to fluctuating pressure.

[0022] 4. The device is provided with a filter component. When the upper filter box is pushed back and forth by the water flow, it can drive the upper filter box to clean the inner wall of the lower filter box to prevent the inner wall of the lower filter box from being blocked by dirt due to long-term use. After a period of use, the filter component can be rotated to separate the L-shaped block from the slot, and the filter component can be taken out for cleaning, so that the device can perform self-cleaning as the device is switched on and off and the water flow pressure changes, preventing blockage due to long-term use.

[0023] 5. This device is provided with a piston and the base is made of heat-insulating material. When the pressure-stabilizing shell is affected by low temperature, the residual water flow inside it will freeze and increase its volume. At this time, the piston will be pushed upward to prevent the water flow from freezing and increasing its volume and bursting the pressure-stabilizing shell. If ice forms at other positions of the device and causes its volume to increase, it will enter the interior of the pressure-stabilizing shell and be buffered by the movement of the piston to prevent the device from being burst by ice.

[0024] 6. During the use of this device, if the water inside the voltage-stabilizing shell freezes due to low temperature, you only need to remove the sealing cover and then inject hot water into the voltage-stabilizing shell to quickly melt the ice inside, thereby increasing the melting speed of the ice, reducing the time that the device cannot be used due to freezing, and improving the use effect.

DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0038] See also Figures 1 to 10 A multi-stage constant flow faucet comprises a base 1, a faucet part 2 is installed at one end of the base 1, a constant pressure part 3 for stabilizing the output water pressure is installed in the middle of the base 1, and a constant flow part 4 for adjusting the water flow size is installed at one end of the base 1 away from the faucet part 2;

[0039] When the device is in use, the water flow will first pass through the flow-regulating component 4 and then enter the interior of the constant pressure component 3. The constant pressure component 3 can stabilize the water flow to prevent the water flow pressure from being too high or too low, and the constant pressure component 3 can separate the air from the water flow to avoid the situation where the water flow is sprayed together with the air. The water flow regulated by the constant pressure component 3 will be input into the interior of the faucet component 2 and finally output to the device through the faucet component 2.

[0040] The flow-regulating component 4 includes a flow-regulating shell 41, a connecting pipe 44 is fixedly installed on one side of the lower surface of the flow-regulating shell 41, and the connecting pipe 44 is used to connect the flow-regulating component 4 and the constant pressure component 3. An inlet pipe 45 for connecting to an external water pipe is fixedly installed on one end of the lower surface of the flow-regulating shell 41 away from the connecting pipe 44. A flow-regulating disk 42 for regulating flow is rotatably installed inside the flow-regulating shell 41. A second sealing column 43 is fixedly installed in the middle of the upper surface of the flow-regulating shell 41, and a second turning handle 46 is rotatably installed in the middle of the second sealing column 43. The central axis of the second turning handle 46 is fixed to the middle of the flow-regulating disk 42. A plurality of evenly distributed multi-stage flow-regulating ports 421 are provided on one side of the flow-regulating disk 42, and the diameters between the plurality of multi-stage flow-regulating ports 421 gradually decrease. A connecting port 422 is provided on the side of the flow-regulating disk 42 away from the multi-stage flow-regulating ports 421, and the connecting port 422 is used to communicate with the connecting pipe 44.

[0041] When in use, first connect the water inlet pipe 45 to the external water outlet pipe, then open the external main water valve to deliver water, at this time, the water will flow into the inside of the water inlet pipe 45, when the constant flow plate 42 is in the initial position, the water inlet pipe 45 is not connected to any of the multi-stage constant flow ports 421, and the connecting port 422 is also not connected to the connecting pipe 44, at this time the constant flow component 4 is in a closed state, the water flow will be blocked by the constant flow plate 42 in the water inlet pipe 45, at this time, turn the second turning handle 46, the second turning handle 46 drives the constant flow plate 42 The rotation makes one of the multi-stage constant flow ports 421 coincide with the water inlet pipe 45, and at the same time, the connecting port 422 is connected to the connecting pipe 44. At this time, the water flow inside the water inlet pipe 45 will pass through the multi-stage constant flow port 421 and enter the interior of the connecting pipe 44 through the connecting port 422, and then be transmitted to the constant pressure component 3 through the connecting pipe 44. If the second turning handle 46 is continuously rotated, the constant flow disk 42 can be driven to rotate, so that the multi-stage constant flow ports 421 of different diameters coincide with the water inlet pipe 45, thereby changing the water inlet amount, and realizing multi-stage constant flow control.

[0042] The constant pressure component 3 includes a pressure stabilizing shell 31, a lower end of one side of the pressure stabilizing shell 31 is provided with an output port 311, a sealing cover 32 is detachably installed on the top of the pressure stabilizing shell 31, and an air hole for balancing the internal air pressure is provided on the sealing cover 32, a filter component 37 for filtering is provided at the inner bottom of the pressure stabilizing shell 31, a piston 35 is provided on the inner sliding card of the pressure stabilizing shell 31, a pressure stabilizing spring 36 is fixedly connected between the piston 35 and the sealing cover 32, and the middle part of the sealing cover 32 is threaded. A threaded sleeve 33 is installed together, and a sliding rod 34 is slidingly provided inside the threaded sleeve 33. One end of the sliding rod 34 away from the threaded sleeve 33 is rotatably installed in the middle of the piston 35, and one end of the threaded sleeve 33 away from the sliding rod 34 is fixedly installed with a first turning handle 39. An air vent 38 is fixedly installed on one side of the pressure stabilizing shell 31. A chamber is formed between the piston 35 and the filter component 37. The bottom end of the air vent 38 is connected to the inside of the chamber, and a sealing plug 381 is detachably installed on the top of the air vent 38.

[0043] When water flows from the connecting pipe 44 into the constant pressure component 3, it will first pass through the filter component 37, and then enter the interior of the pressure-stabilizing shell 31 after being filtered by the filter component 37. At the same time, it will be transmitted to the faucet component 2 through the output port 311. If the water pressure entering the pressure-stabilizing shell 31 is moderate, the water will directly enter the interior of the faucet component 2 through the output port 311. If the pressure suddenly increases or decreases at this time, the faucet component 2 can automatically adjust different flow rates according to the pressure. When the pressure suddenly increases, the liquid in the pressure-stabilizing shell 31 will not all flow into the interior of the faucet component 2 at once, but will push the piston 35 up, and the piston 35 compresses the pressure-stabilizing spring. 36, when used in conjunction with the faucet component 2, it is possible to prevent high pressure from causing water jetting. When the pressure gradually decreases, the pressure-stabilizing spring 36 releases the thrust on the piston 35, and slowly releases the pressure inside the pressure-stabilizing shell 31 until it returns to a moderate pressure state. When water flows into the pressure-stabilizing shell 31, an initial pressure will be generated inside the pressure-stabilizing shell 31. At this time, if the pipeline pressure drops suddenly, the pressure-stabilizing spring 36 can release part of the pressure, so that the water flow output to the faucet component 2 is relatively stable, and the water flow output from the faucet component 2 will not fluctuate due to changes in pressure, thereby reducing the impact of pressure on the device and making it more comfortable to use.

[0044] When the water flow of the input device entrains a lot of air, the sealing plug 381 can be opened. At this time, when the liquid entrains the air into the pressure-stabilizing shell 31, the air and water flow flows at the bottom of the pressure-stabilizing shell 31 through the output port 311 into the interior of the faucet component 2, and the air will push the piston 35 upward. In the initial state, the piston 35 will block the lower end of the air pipe 38, and when pushed by the gas, it will drive the piston 35 to move upward. At this time, the piston 35 moves to above the lower end of the air pipe 38, and the air will be ejected from the air pipe 38. When the gas is ejected from the air pipe 38, the pressure inside the pressure-stabilizing shell 31 is reduced. Under the action of the pressure-stabilizing spring 36, the piston 35 is pushed again to block the lower end of the air pipe 38, so that the air entrained in the water flow can be filtered out in advance to prevent the water flow and gas from being ejected together during use, thereby improving the stable output of the water flow and the comfort of use.

[0045] Because of different usage scenarios, for some high floors or construction sites, the water supply pressure is generally relatively large. At this time, the piston 35 can be driven to rise by turning the first turning handle 39. At this time, the piston 35 compresses the pressure-stabilizing spring 36, so that the force generated by the pressure-stabilizing spring 36 is greater and can cope with greater water flow pressure, which is convenient for adjusting the appropriate thrust according to different usage scenarios.

[0046] The faucet component 2 includes a first sealing cylinder 21, and a water outlet faucet 22 is rotatably installed on the upper end of the first sealing cylinder 21. The upper end of the water outlet faucet 22 extends to the outside of the first sealing cylinder 21 and is in an arc shape. The water outlet faucet 22 is connected to the inside of the second pipe 24 through the water outlet port 241. A first pipe 23 is fixedly connected between the first sealing cylinder 21 and the constant pressure component 3. One end of the first pipe 23 away from the second pipe 24 is fixedly installed inside the output port 311. The bottom end of the first sealing cylinder 21 is fixedly installed with the second pipe 24. The second pipe 24 is fixedly installed with the first pipe 23, the inner sliding card of the first pipe 23 is provided with a third pipe 25, the inner part of the first pipe 23 is fixedly installed with a fixing ring 231, a primary spring 232 is fixedly connected between the fixing ring 231 and the third pipe 25, the middle part of the second pipe 24 has a water outlet port 241, the end of the third pipe 25 away from the primary spring 232 is provided with a water outlet 251, the inner end of the second pipe 24 away from the first pipe 23 is provided with a secondary spring 242, and the secondary spring 242 is fixedly installed on the inner wall of the first sealing cylinder 21.

[0047] When the water flows through the constant pressure component 3 and is stabilized, it will enter the interior of the first pipe 23 through the output port 311. Because the fixing ring 231 and the water outlet port 241 are staggered when the device is closed, when the water flows into the third pipe 25, the third pipe 25 will be pushed to move. When the water pressure is in a constant pressure state, the overlap between the water outlet 251 and the water outlet port 241 is the highest, and the third pipe 25 is supported by the secondary spring 242. When the water flow input into the third pipe 25 suddenly increases, the force pushing the third pipe 25 will also increase. At this time, the thrust generated by the third pipe 25 will also increase, and the secondary spring 242 will increase the thrust generated by the third pipe 25. The spring 242 is pushed and compressed, which causes the excessive movement of the third pipe 25, which will cause the overlap between the water outlet 251 and the water outlet port 241 to decrease. At this time, the flow through the water outlet 251 and the water outlet port 241 is restricted, and the increase in pressure will cause the flow rate of the liquid to increase. Therefore, the total amount of water output is kept constant by reducing the flow rate of the liquid. When the water pressure is reduced to a constant water pressure, the secondary spring 242 will push the third pipe 25 again to increase the overlap between the water outlet 251 and the water outlet port 241, thereby increasing the liquid flow rate and preventing the liquid flow from fluctuating due to fluctuating pressure.

[0048] The base 1 has a first chamber 11 corresponding to the first sealing column 21, and the first sealing column 21 is fixedly installed inside the first chamber 11. The middle of the base 1 has a second chamber 12 corresponding to the constant pressure component 3, and the pressure stabilizing shell 31 is fixedly installed inside the second chamber 12. The base 1 has a third chamber 13 at a position corresponding to the constant flow component 4, and the constant flow shell 41 is fixedly installed inside the third chamber 13. The constant flow component 4 is fixedly installed inside the third chamber 13. The second chamber 1 2 is provided with a card slot 14 at the inner bottom end, the filter component 37 includes a lower filter box body 371, and an upper filter box body 372 is slidably carded inside the lower filter box body 371. The lower filter box body 371 and the upper filter box body 372 are combined to form a whole filter cylinder. A center hole 373 is provided in the middle of the lower filter box body 371, and one end of the connecting pipe 44 away from the constant flow housing 41 extends to the inside of the center hole 373. An L-shaped card block 374 corresponding to the card slot 14 is fixedly installed on the lower surface of the lower filter box body 371.

[0049] After passing through the flow-regulating component 4, the water flow will first be input into the interior of the lower filter box body 371 through the center hole 373. When the device is in a closed state, the upper filter box body 372 is located inside the lower filter box body 371 to form a box body. When the device is opened and water flows into the interior of the lower filter box body 371, because the water flow will pass through the upper filter box body 372 and enter the interior of the pressure-stabilizing shell 31, it will have a pushing effect on the upper filter box body 372. The output port 311 is located on one side of the lower filter box body 371 and fits the side wall of the lower filter box body 371. When the device is closed, the water flow inside the pressure-stabilizing shell 31 will be pushed by the pressure-stabilizing spring 36 to re-enter the interior of the lower filter box body 371 and flow out through the faucet component 2. When the liquid passes through the upper filter box body 372 from the interior of the pressure-stabilizing shell 31 and enters the interior of the lower filter box body 371, it will The upper filter box body 372 produces a pushing effect, causing it to drop back into the interior of the lower filter box body 371 and return to its initial state. Because the upper filter box body 372 is slidably clamped in the interior of the lower filter box body 371, when the upper filter box body 372 is pushed back and forth by the water flow, it can drive the upper filter box body 372 to clean the inner wall of the lower filter box body 371, thereby preventing the inner wall of the lower filter box body 371 from being blocked by dirt due to long-term use. After a period of use, the sealing cover body 32 can be disassembled to remove the piston 35 and the pressure-stabilizing spring 36, and then the filter component 37 can be rotated to separate the L-shaped block 374 from the slot 14. At this time, the filter component 37 can be taken out for cleaning, so that the device can perform self-cleaning as the device is switched on and off and the water flow pressure changes, thereby preventing blockage due to long-term use.

[0050] The special internal structure of a multi-stage constant-flow faucet will cause a large amount of water to be retained inside for a long time. At this time, if the external environment is in a low temperature state, the water inside the water pipe will freeze, and the volume of the water will suddenly increase after freezing. The faucet is exposed to the outside, which can easily cause the water inside to freeze and increase in volume, causing the multi-stage constant-flow faucet to be burst by ice and cause damage to the faucet.

[0051] Therefore, the device is provided with a piston 35, the base 1 adopts a heat-insulating material, and the second pipe 24, the first pipe 23 and the connecting pipe 44, the water inlet pipe 45 are all located inside the base 1, which can prevent freezing. When the pressure-stabilizing shell 31 is affected by low temperature, the residual water flow inside it will freeze and increase in volume. At this time, the piston 35 will be pushed upward to prevent the water flow from freezing and causing the volume to increase and burst the pressure-stabilizing shell 31. If ice forms at other positions of the device and causes its volume to increase, it will enter the interior of the pressure-stabilizing shell 31 and be buffered by the movement of the piston 35 to prevent the device from being burst by ice.

[0052] If the water inside the voltage-stabilizing shell 31 freezes due to low temperature, you only need to remove the sealing cover 32 and then inject hot water into the voltage-stabilizing shell 31 to quickly melt the ice inside, thereby increasing the melting speed of the ice, reducing the unusable time due to freezing, and improving the use effect.

[0053] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto.
