Description

Technical Field

[0001] The invention belongs to the technical field of faucet valve cores, in particular to a two-inlet and two-outlet faucet valve core. Background Art

[0002] The faucet valve core is a key component in the faucet, which is used to control the opening and closing of the faucet. With the increase in life needs, various faucets have appeared on the market to meet people's life needs and realize different water inlet and outlet methods. Faucet valve cores with reliable quality can effectively reduce water leakage. The current mainstream faucet valve cores include one-in-one-out, two-out, two-in-one-out, two-in-two-out, etc. At present, the two-in-two-out faucet valve core is mainly used in shower facilities. The two-out type realizes that the fixed shower head and the hand-held shower head can be used separately, and the two-in-type is used to introduce cold water and hot water. However, the two-in-two-out faucets on the market are mainly controlled by two valve cores, which requires adjusting the two valve cores at the same time during use, which makes the use process more inconvenient, and the use of multiple valve cores increases the cost of use.

[0003] In order to realize the two-inlet and two-outlet type of faucet in the existing technology, two independent valve cores are mainly used to adjust the water outlet position. However, the two valve cores need to be controlled separately during adjustment, and frequent adjustments are required during use, which makes it inconvenient to use and increases the cost of the valve core. At the same time, due to the poor water quality in some areas and the aging of water source pipelines due to long-term use, there are more suspended matter inside, and the existing valve core cannot process these suspended matter, resulting in a lot of suspended matter in the water flowing out through the valve core after long-term use, thereby affecting the health of the user. In addition, the existing two-inlet and two-outlet valve core can be directly opened when hot water is passed into it, which can easily cause scalding when children touch it by mistake.

[0004] In view of this, the present invention solves the above technical problems by proposing a two-inlet and two-outlet faucet valve core. Summary of the invention

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0032] like Figures 1 to 8 As shown, a two-inlet and two-outlet faucet valve core of the present invention comprises a valve body 1, a water inlet pipe 2, a water outlet pipe 3 and a valve core 4. A guide groove 11 is provided inside the left and right sides of the valve body 1, and the two ends of the guide groove 11 are respectively connected to the water inlet pipe 2 and the water outlet pipe 3;

[0033] The valve core 4 is arranged at the middle of the upper end of the valve body 1, and the valve core 4 is rotatably and slidably connected to the valve body 1. A valve ring 41 is arranged at the inner lower end of the valve core 4. The valve ring 41 body is rotatably connected to the inside of the valve body 1. A water flow hole 45 is provided on the inner side of the valve ring 4. A rib rod 42 is fixedly connected to the outer side of the lower end of the valve core 4. A rib groove 411 corresponding to the width of the rib rod 42 is provided on the inner side of the valve ring 41. The rib rod 42 is embedded in the inside of the rib groove 411. The valve core 4 can drive the valve ring 41 to rotate through the cooperation of the rib rod 42 and the rib groove 411.

[0034] The filter screen 5 is arranged inside the guide groove 11, and the filter screen 5 is rotatably connected to the inside of the guide groove 11. A support rod 12 is arranged on the outside of the filter screen 5, and the support rod 12 is threadedly connected to the valve body 1. The inner side of the support rod 12 is rotatably connected to a rotating rod 14. The filter screen 5 is used to filter impurities in the water source. The rotating rod 14 is distributed in a ring with the center of the support rod 12 as the rotating axis. The outer end of the rotating rod 14 is rotatably connected to a sliding rod 15, and the inner edge of the sliding rod 15 is fixedly connected to the outer end edge of the filter screen 5 and points to the axial direction of the support rod 12.

[0035] During operation, firstly, a cold water area and a hot water area are respectively arranged inside the valve body 1, and the cold water area and the hot water area are relatively distributed. One side of the water inlet pipe 3 on the right side of the front of the valve body 1 is set as the cold water area, and then cold water and hot water are respectively connected to the two sides of the water inlet pipe 2. When it is necessary to release cold water during use, the valve core 4 is rotated counterclockwise, so that the valve core 4 drives the valve ring 41 to rotate through the rib rod 42 and cooperates with the No. 1 rib groove 411, so that the valve ring 41 drives the water flow hole 45 to correspond to the position of the guide groove 11 in the right cold water area, so that the cold water enters the guide groove 11 through the water inlet pipe 2, and then the cold water passes through the filter screen 5 and drives the filter screen 5 to rotate, so that the suspended matter in the cold water is intercepted on the filter screen 5 with a mesh number of 400 to 800, and the filter screen 5 rotates with the flow of cold water, ensuring that each filter screen 5 is evenly distributed. The filter screen 5 can intercept suspended matter on all sides to avoid the situation where too much suspended matter is accumulated on a single side of the filter screen 5. At the same time, when installing the filter screen 5, the rotating rod 14 is folded so that the filter screen 5 can pass through the threaded connection position between the two sides of the valve body 1 and the support rod 12. Then, after the filter screen 5 is completely in the guide groove 11 inside the valve body 1, the support rod 12 is rotated so that the rotating rod 14 is pressed and rotated to support the filter screen 5, so that the outer circumference of the filter screen 5 is increased, thereby increasing the working area of ​​the filter screen 5 and avoiding the need to frequently replace the filter screen 5. The hot water area adopts the same filtering method as the cold water area, ensuring that under the same water quality conditions, compared with the existing two-inlet and two-outlet faucet valve core, the device can effectively reduce the suspended matter in the water flowing out of the faucet, thereby effectively improving the quality of the outflowing water.

[0036] As a specific implementation of the present invention, the inlet 111 and the outlet 112 in the guide groove 11 on both sides of the filter screen 5 in the cold water area and the hot water area are staggered in position.

[0037] During operation, the inlet 111 and the outlet 112 in the guide groove 11 on both sides of the filter 5 in the cold water area and the hot water area are staggered up and down, so that the water source in the guide groove 11 needs to flow from the inlet 111 above the filter 5 to the outlet 112 below, so that the water source in the guide groove 11 can fully contact with the filter 5, thereby increasing the contact area between the filter 5 and the water source. At the same time, the water source drives the filter 5 to rotate, so that a rotating water flow is formed outside the filter 5. At the same time, part of the water source continues to rotate with the filter 5, so that the contact time between the water source and the filter 5 is increased, thereby maximizing the interception effect of the filter 5 on the suspended matter in the water source, and ensuring that the suspended matter in the water flow can be evenly covered on the filter 5, avoiding the suspended matter from being concentrated in a certain place on the filter 5, thereby affecting the filtering effect of the filter 5.

[0038] As a specific embodiment of the present invention, a magnetic ball 51 is arranged inside the inner side of the filter screen 5 and surrounded by the sliding rod 15 .

[0039] When working, the magnetic ball 51 inside the filter 5 is used to absorb some rust impurities passing through the iron pipe and the iron valve body 1, so as to prevent more rust impurities from appearing inside the pipe due to long-term use, resulting in excessive rust impurities in the water during use, leading to excessive absorption of iron elements when drinking, and preventing the iron content in drinking water from exceeding 0.3 mg / L. At the same time, rust impurities are easy to adhere to the inner wall of the guide groove 11 of the valve body 1 during the flow process. When too much rust impurities are accumulated, the flow rate of the water will be reduced, affecting the water use experience.

[0040] As a specific implementation of the present invention, the distance between adjacent sliding rods 15 is smaller than the length of the filter screen 5 between adjacent sliding rods 15 .

[0041] When working, the distance between adjacent sliding rods 15 is smaller than the length of the filter screen 5 between adjacent sliding rods 15, so that the filter screen 5 between the sliding rods 15 forms an arc surface and is concave toward the inner side of the sliding rod 15, thereby increasing the working area of ​​the filter screen 5, so that the filter screen 5 has a larger area for filtering suspended matter in the water during the process of filtering the water source. At the same time, the arc surface of the filter screen 5 can effectively disperse the impact force of the water source in the guide groove 11, and avoid the filter screen 5 from falling off under long-term impact, causing the filter screen 5 to lose the function of filtering the water source.

[0042] As a specific implementation of the present invention, a connecting rod is fixedly connected between the inner middle portion of the filter screen 5 and the magnetic ball 51 .

[0043] During operation, the connecting rod is fixedly connected between the filter screen 5 and the magnetic ball 51, and the connecting rod can ensure the stability of the magnetic ball 51, so that the magnetic ball 51 can work stably under the impact of water flow. At the same time, the concave arc surfaces of the filter screen 5 uniformly distributed between adjacent sliding rods 15 are interconnected through the connecting rod and the magnetic ball 51, so that the filter screens 5 are pulled by each other through the connecting rod, ensuring that the filter screen 5 can still maintain the state of the arc surface under the impact of water flow, thereby improving the stability of the filter screen 5 during operation.

[0044] As a specific implementation of the present invention, the outer side of the magnetic ball 51 is fixedly connected with a retaining rod 511 , and the retaining rod 511 is evenly and densely distributed on the outer side of the magnetic ball 51 .

[0045] During operation, the intercepting rod 511 on the outside of the magnetic ball 51 is used to further intercept tiny suspended matter in the water source through the tiny barbs on the surface of the intercepting rod 511, thereby reducing the suspended matter in the outflowing water. At the same time, the intercepting rod 511 is used to interfere with rust impurities in the water source, thereby improving the adsorption of rust impurities by the magnetic ball 51, thereby preventing the rust impurities from flowing too fast under the action of the water flow and affecting the adsorption effect of the magnetic ball 51.

[0046] As a specific implementation of the present invention, a spring rod 13 is slidably connected inside the support rod 12 , and the spring inside the spring rod 13 is initially in a compressed state under the action of the magnetic ball 51 .

[0047] During operation, when a large amount of rust impurities are adsorbed on the surface of the magnetic ball 51, and a large amount of tiny suspended matter is trapped on the interception rod 511, the adsorption capacity of the magnetic ball 51 is reduced, thereby reducing the adsorption force of the magnetic ball 51 on the spring rod 13, causing the spring in a compressed state under the action of the magnetic ball 51 to begin to release elastic potential energy, so that the spring rod 13 pops out, reminding the user to clean the filter 5.

[0048] As a specific embodiment of the present invention, a protrusion 43 is fixedly connected to the outer side of the valve core 4, and a slope is provided on the outer side of the protrusion 43. A stop plate 44 is provided above the protrusion 43. The stop plate 4 is slidably connected to the inside of the valve body 1, and the stop plate 4 is arranged in the hot water area inside the valve body 1; a circular hole 441 with the same diameter as the water flow hole 45 inside the valve ring 41 is provided inside the stop plate 44 and close to the side of the valve core 4.

[0049] During operation, when the hot water area is not opened, the stop plate 44 blocks the guide groove 11 in the hot water area, so that the hot water in the hot water area cannot flow. When hot water is used, the valve core 4 rotates clockwise to drive the valve ring 41 to rotate through the rib rod 42, so that the valve ring 41 drives the water flow hole 45 to correspond to the guide groove 11 in the hot water area, and partially opens the guide groove 11 in the hot water area. Because the valve core 4 is rotated and slidably connected with the valve body 1, the valve core 4 is pulled upward, so that the valve core 4 drives the protrusion 43 to move upward, and the protrusion 43 is An inclined surface is provided on the outer side of 43, so that the protrusion 43 pushes the stop plate 44 to move toward the guide groove 11 in the hot water area, and the circular hole 441 on the stop plate 44 corresponds to the position of the guide groove 11, so that the guide groove 11 in the hot water area is fully opened, so that hot water can flow in the guide groove 11. The stop plate 44 provides double insurance for the guide groove 11 in the hot water area, ensuring that the hot water will not flow out directly from the rotating valve core 4 when hot water needs to be released, avoiding the situation where children accidentally touch it and get scalded.

[0050] As a specific embodiment of the present invention, a No. 2 rib groove 16 corresponding to the width of the rib rod 42 is opened inside the valve body 1 and close to the valve core 4. The valve core 4 is in an initial state, and the angle between the position of the No. 2 rib groove 16 and the initial position of the No. 1 rib groove 411 inside the valve ring 41 is 90°.

[0051] During operation, when hot water needs to be released, the valve core 4 is rotated clockwise by 90°, so that the valve core 4 drives the valve ring 41 to rotate through the rib rod 42, so that the water flow hole 45 corresponds to the guide groove 11 in the hot water area. At the same time, because the angle between the position of the No. 2 rib groove 16 and the initial position of the No. 1 rib groove 411 inside the valve ring 41 is 90°, the rib rod 42 corresponds to the No. 2 rib groove 16 inside the valve body 1, so that the direction in which the valve core 4 slides up and down will not be deflected, so that the valve core 4 can push the stop plate 44 to move, and the guide groove 11 in the hot water area is fully opened. At the same time, after the valve core 4 is reset, the valve body 1 can block the rib rod 42, thereby preventing the valve core 4 from sliding up and down after it is reset.

[0052] The specific workflow is as follows:

[0053] According to the distribution of the cold water area and the hot water area inside the valve body 1, the cold water and the hot water are respectively connected to the two sides of the water inlet pipe 2. When the cold water needs to be released during use, the valve core 4 is rotated counterclockwise to drive the valve ring 41 to rotate, so that the valve ring 41 drives the water flow hole 45 to correspond to the position of the guide groove 11 in the cold water area on the right side, so that the cold water enters the guide groove 11 through the water inlet pipe 2, and then the cold water passes through the filter screen 5 and drives the filter screen 5 to rotate, so that the suspended matter in the cold water is intercepted on the filter screen 5 with a mesh number of 400 to 800, and the filter screen 5 rotates with the flow of cold water, ensuring uniform Each surface of the evenly distributed filter 5 can intercept suspended matter, etc. At the same time, when installing the filter 5, the rotating rod 14 is folded so that the filter 5 can pass through the threaded connection position between the two sides of the valve body 1 and the support rod 12. Then, after the filter 5 is completely in the guide groove 11 inside the valve body 1, the support rod 12 is rotated so that the rotating rod 14 is pressed and rotated to prop up the filter 5, so that the outer circumference of the filter 5 is increased, thereby increasing the working area of ​​the filter 5. The hot water area adopts the same filtering method as the cold water area, which effectively reduces the suspended matter in the water flowing out of the faucet.

[0054] In order to verify the specific use effect of the present invention, the applicants of the present invention conducted the following 1-2 experiments:

[0055] Testing instrument: 78-parameter water quality tester, the model on the market is ZBS-M5825-1 two-inlet and two-outlet faucet, and the faucet with two-inlet and two-outlet valve core in the present invention;

[0056] Control variables: The water source was the same, the taps in Experiment 1 and Experiment 2 were not in use, the water flow rate and flow rate per minute were the same, the water source temperature was the same, and the weather during the test was the same;

[0057] Experiment 1:

[0058] According to the usage time of the two-inlet and two-outlet faucet valve core, the suspended matter in the outflowing water is detected by the 78-parameter water quality detector according to different usage times, so as to judge the quality of the outflowing water. First, the faucet with the two-inlet and two-outlet valve core in the present invention is connected to the water source, and the inside of the valve body 1 is not cleaned during the experiment. The 78-parameter water quality detector is used to detect the water quality five times at different time periods within one year, and the water quality data of each detection is recorded, and the recorded data is statistically formed into the following Table 1:

[0059] Table 1

[0060]

[0061] Experiment 2:

[0062] According to the use time of the ZBS-M5825-1 two-inlet and two-outlet faucet valve core in the prior art, and the situation that there is no filter 5 inside, the suspended matter in the water quality is tested according to different use times by using a 78-parameter water quality detector, and one year is used as the detection base. Then, under the condition of the same water source, the water quality is tested five times at different time periods within one year, and the water quality data of each test is recorded, and the recorded data is statistically formed into the following Table 2:

[0063] Table 2

[0064]

[0065] Schedule:

[0066] National tap water quality standards (part)

[0067] Test items unit National Standards Iron 0.8 mg / L ≦0.3 copper mg / L ≦1 Turbidity 20 NTU ≦3 High suspended matter ppm ≦300

[0068] Comparing the test data in Table 1 and Table 2 above with the national tap water quality standards in the attached table, we can see that:

[0069] The two-inlet and two-outlet faucet of the present invention in Table 1 is used continuously for one year without cleaning the inside of the valve body 1. According to the test data in Table 1, it can be seen that the content of suspended matter in the water flowing out of the faucet can still be kept below the national water quality standard value after the two-inlet and two-outlet valve core used in the present invention is used continuously for one year;

[0070] When the ZBS-M5825-1 two-inlet and two-outlet faucet on the market in Table 2 is used continuously for one year, the iron, copper, turbidity and high suspended solids in the water flowing out of the faucet gradually increase with the increase of use time, and the copper content in the water exceeds the existing national standard value of tap water quality after three consecutive months of use. After six consecutive months of use, the test data of various suspended solids exceed the existing national standard value of tap water quality;

[0071] To sum up, when the internal valve core of the faucet using the two-inlet and two-outlet valve core of the present invention and the ZBS-M5825-1 two-inlet and two-outlet faucet in the existing market were not cleaned during the experiment, the faucet using the two-inlet and two-outlet valve core of the present invention was better than the ZBS-M5825-1 two-inlet and two-outlet faucet in the existing market. After the two-inlet and two-outlet faucet of the present invention was used continuously for one year, various internal test data of the water flowing out of the faucet could still be maintained below the national tap water quality standard, effectively ensuring the water quality of users, and effectively proving that the faucet using the two-inlet and two-outlet valve core of the present invention is better at treating suspended matter than the same type of two-inlet and two-outlet faucet in the prior art and has more superior performance.

The valve core (4) is connected to the valve body (1) through the rib rod (42) and the rib groove (411). The cooperation can drive the valve ring (41) to rotate; the filter screen (5) is arranged inside the guide groove (11), and the filter screen (5) is rotatably connected to the inside of the guide groove (11); a support rod (12) is arranged outside the filter screen (5), and a rotating rod (14) is rotatably connected inside the support rod (12); the filter screen (5) is used to filter impurities in the water source; the rotating rod (14) is distributed in a ring shape with the center of the support rod (12) as the rotating axis; the outer end of the rotating rod (14) is rotatably connected to a sliding rod (15); the inner edge of the sliding rod (15) is fixedly connected to the outer end edge of the filter screen (5) and points to the axial direction of the support rod (12); During operation, firstly, a cold water area and a hot water area are respectively arranged inside the valve body (1), and the cold water area and the hot water area are arranged oppositely. One side of the water inlet pipe (2) on the right side of the front of the valve body (1) is set as the cold water area, and then the water inlet pipes (2) on both sides are connected to the cold water and hot water respectively. When it is necessary to release the cold water during use, the valve core (4) is rotated counterclockwise, so that the valve core (4) drives the valve ring (41) to rotate through the rib rod (42) and cooperates with the first rib groove (411), so that the valve ring (41) drives the water flow hole (45) to correspond to the position of the guide groove (11) in the right cold water area, so that the cold water enters the guide groove (11) through the water inlet pipe (2), and then the cold water passes through the filter screen (5) and drives the filter screen (5) to rotate, so that the cold water flows into the guide groove (11) through the water inlet pipe (2), and then the cold water flows into ... guide groove (11) through the filter screen (5) and drives the filter screen (5) to rotate, so that the cold water flows into the guide groove (11) through the water inlet pipe (2), and then the cold water flows into the guide groove (11) through the filter screen (5) and drives the filter screen (5) to rotate, so that the cold water flows into the guide groove ( Suspended matter in the water is intercepted on the filter screen (5) with a mesh size of 400 to 800, and the filter screen (5) rotates with the flow of cold water, ensuring that each surface of the evenly distributed filter screen (5) can intercept the suspended matter, thereby preventing the accumulation of too much suspended matter on a single surface of the filter screen (5). At the same time, when installing the filter screen (5), the rotating rod (14) is folded so that the filter screen (5) can pass through the threaded connection position between the two sides of the valve body (1) and the support rod (12). Then, after the filter screen (5) is completely in the guide groove (11) inside the valve body (1), the support rod (12) is rotated, so that the rotating rod (14) is pressed and rotated to support the filter screen (5), thereby increasing the outer perimeter of the filter screen (5); When the hot water area is not opened, the stop plate (44) blocks the guide groove (11) in the hot water area, so that the hot water in the hot water area cannot flow. When hot water is used, the valve core (4) rotates clockwise to drive the valve ring (41) to rotate through the rib rod (42), so that the valve ring (41) drives the water flow hole (45) to correspond to the guide groove (11) in the hot water area, and partially opens the guide groove (11) in the hot water area. Because the valve core (4) and the valve body (1) are rotated and slidably connected, the valve core (4) is then pulled upward, and the valve core (4) is opened from The valve core (4) drives the protrusion (43) to move upward, and an inclined surface is provided on the outer side of the protrusion (43), so that the protrusion (43) pushes the stop plate (44) to move in the direction of the guide groove (11) in the hot water area, and the circular hole (441) on the stop plate (44) corresponds to the position of the guide groove (11), so that the guide groove (11) in the hot water area is fully opened, so that hot water can flow in the guide groove (11), and the stop plate (44) provides double insurance for the guide groove (11) in the hot water area; A protrusion (43) is fixedly connected to the outer side of the valve core (4), an inclined surface is arranged on the outer side of the protrusion (43), a stop plate (44) is arranged above the protrusion (43), the stop plate (44) is slidably connected to the inside of the valve body (1), and the stop plate (44) is arranged in the hot water area inside the valve body (1).
