[0002] In the field of modern domestic water treatment, water purification devices are increasingly widely used to ensure the safety and health of drinking water. As one of the important components of the water purification system, the water purification tee valve is mainly responsible for connecting different pipelines and switching the direction of water flow.

[0003] The traditional water purification tee valve adopts a straight push type operating mechanism, which meets the basic functional requirements to some extent, but still has several shortcomings:

[0004] 1. The design of the traditional water purification tee valve often requires professional installation, which is inconvenient and increases the installation cost and reduces the user experience.

[0005] 2. Under the action of high-pressure water flow, the existing straight push type control structure is prone to looseness or misoperation, which leads to water leakage or unstable water pressure, causing safety hazards and economic losses to users.

[0006] 3. Since the switch action needs to directly resist the pressure of water flow, the operation feels poor, and users may feel a large resistance during use, which may cause fatigue after a long time of use, especially in environments with high water pressure, which is more obvious.

[0007] Therefore, the present inventors have specially designed a quick connection water purification tee valve, which gives rise to the present case. CONTENT OF THE UTILITY MODEL

[0038] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clear and understandable, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0039] See also Figs. 1 to 6 , is a quick-connect water purification three-way valve as the best embodiment of the utility model, comprising:

[0040] The main valve body 10 is in the shape of a cylindrical tube. A main water channel 11 is opened in the interior of the main valve body 10 along its axial direction and pipeline interface structures are respectively provided at both ends. In this embodiment, the pipeline interface structures respectively include a third external thread 12 provided on the outer peripheral side of one end of the main valve body 10 and a second nut sleeve 13 threadedly matched with the outer peripheral side of the other end of the main valve body 10. A third internal thread 131 is provided on the inner side of the second nut sleeve 13. A portion of the third internal thread 131 is threadedly connected to the end of the main valve body 10 and the remaining portion is used to threadably connect to the corresponding water inlet pipeline. A sealing gasket 14 for sealing is also provided on the inner side of the second nut sleeve 13 and at the opening position of the main water channel 11 to enhance the overall sealing performance;

[0041] The bypass pipe 20 protrudes vertically from one side of the main valve body 10 and is formed with a water inlet chamber 40 and an independent water outlet chamber 50 connected to the main water channel 11. The water inlet chamber 40 and the water outlet chamber 50 respectively form a water inlet hole 41 and a water outlet hole 51 that penetrate the side wall of the bypass pipe 20;

[0042] The rotating control sleeve 30 is cylindrical as a whole, and a through groove 31 is provided in the middle of the rotating control sleeve 30 along its axial direction, which is clearance-matched with the bypass pipe 20. The inner side of the through groove 31 is threadedly connected to the outer side of the bypass pipe 20, and is used to move toward the length direction of the bypass pipe 20 as the rotating control sleeve 30 rotates, so as to open or close the passage between the water inlet hole 41 and the water outlet hole 51.

[0043] In this embodiment, the main valve body 10 and the bypass pipe 20 are integrally formed by stainless steel material. Compared with the tee valve on the market through assembly form, it not only saves the installation steps, but also has higher structural strength, is not easy to deform, and has higher reliability.

[0044] Preferably, the bypass pipe 20 is columnar, and an end thereof away from the main valve body 10 is provided with a water outlet joint 21 leading out the water cavity 50. The bypass pipe 20 is provided with a first external thread 22 at an end close to the water outlet joint 21 and at an outer peripheral side thereof, and a first nut sleeve 23 threadedly connected with the first external thread 22. An inner side of the first nut sleeve 23 is provided with a first internal thread 231 threadedly matched with the first external thread 22.

[0045] In this embodiment, the water inlet cavity 40 and the water outlet cavity 50 are both axially provided through the bypass pipe 20. The water inlet cavity 40 extends along the middle part of the bypass pipe 20 to the main water passage 11 inside the main valve body 10 to achieve water leading. The water outlet cavity 50 extends along one side of the water inlet cavity 40 to an end of the bypass pipe 20 away from the main valve body 10 and forms an opening to form a water passage for water outlet. The water inlet cavity 40 and the water outlet cavity 50 are both provided through and extend to the water inlet hole 41 and the water outlet hole 51 on the outer peripheral surface of the bypass pipe 20 at the middle part of the bypass pipe 20.

[0046] In addition, in order to achieve water passage leading between the water inlet cavity 40 and the water outlet cavity 50, the inner side wall of the through slot 31 of the rotary control sleeve 30 is inwardly recessed and annularly provided with a water guide groove 33. The water guide groove 33 has a water outlet position completely covering the water inlet hole 41 and the water outlet hole 51 to achieve water guiding, and a closed position only covering the water inlet hole 41.

[0047] Specifically, the water guide groove 33 has an axial extension distance D1 along the rotary control sleeve 30. The water inlet hole 41 and the water outlet hole 51 have a maximum axial extension distance D2 along the bypass pipe 20. In order to achieve water inlet and water stop control, D1≥D2 needs to be met. In this embodiment, the extension distance D1 of the water guide groove 33 is designed such that when it is at a side closest to the main valve body 10, the water guide groove 33 only covers the area corresponding to the water inlet hole 41, and at this time, water flow cannot enter the water outlet hole 51 through the water guide groove 33. When the rotary control sleeve 30 is threadedly rotated to a position away from the main valve body 10, the water guide groove 33 gradually moves along the position of the water inlet hole 41 to a position capable of completely covering the water outlet hole 51. Thus, through the design of the water guide groove 33, the water inlet hole 41 and the water outlet hole 51 can be achieved to be led through and closed by cooperating with the thread matching structure between the rotary control sleeve 30 and the bypass pipe 20, thereby facilitating the water inlet and outlet control of the tee valve.

[0048] Compared with the original straight push type control structure, the rotary control sleeve 30 needs to be rotated to a position where the water guide groove 33 at least partially covers the water outlet hole 51 to achieve water outlet, thereby greatly reducing the probability of misoperation and water leakage.

[0049] In addition, the inner diameter of the water outlet cavity 50 is smaller than that of the water inlet cavity 40, and the water outlet joint 21 is suitable for the connection of a thin pipe of a clean water pipeline, and is connected to the clean water pipeline conveniently and quickly through the first nut sleeve 23, so that the inner diameter of the water outlet cavity 50 is reduced to be suitable for the connection of the clean water pipeline.

[0050] Preferably, the second external thread 24 is arranged on the outer circumferential side of the bypass pipe 20 and between the water outlet hole 51 and the first external thread 22, and the second internal thread 32 is arranged on the inner side wall of the through slot 31 and away from the main valve body 10.

[0051] Therefore, through the thread cooperation between the second external thread 24 and the second internal thread 32, the rotation of the control sleeve 30 can be conveniently controlled by rotating, and the displacement of the control sleeve 30 in the axial direction of the bypass pipe 20 is realized, so as to change the coverage state of the water guide groove 33 with the water inlet hole 41 and the water outlet hole 51, and finally to conveniently realize the control of the open and closed state of the water communication between the water inlet cavity 40 and the water outlet cavity 50.

[0052] In the embodiment, the outer diameter of the first external thread 22 is smaller than that of the second external thread 24, that is, the end of the bypass pipe 20 away from the main valve body 10 forms a retracted columnar structure, and the maximum outer diameter of the first nut sleeve 23 is designed to be the same as the maximum outer diameter of the rotating control sleeve 30, so that the outer circumferential side of the entire bypass pipe 20 is in a relatively flat state, and the overall appearance is improved.

[0053] Preferably, the second external thread 24 and the second internal thread 32 are both multi-start threads.

[0054] In the embodiment, the second external thread 24 and the second internal thread 32 are double-start threads that can cooperate with each other. Compared with single threads, the double-start threads have a higher helix angle, and the friction force formed by the screwing between the rotating control sleeve 30 and the bypass pipe 20 is reduced, so that the rotating control sleeve 30 can move a larger amount each time and has a lighter feel, and the number of rotation required for controlling the waterway switch is reduced, thereby providing a better user experience.

[0055] Preferably, the first clamping groove 25 is arranged between the second external thread 24 and the first external thread 22 and surrounds the outer circumferential side of the bypass pipe 20, and the limiting stop ring 26 for limiting the displacement position of the outermost side of the rotating control sleeve 30 is detachably clamped in the first clamping groove 25.

[0056] In the embodiment, the limiting clamping groove is an annular clamping member with a notch, which can be made of plastic or metal. The outer side thereof needs to extend to a position capable of blocking the rotating control sleeve 30, so as to avoid the rotating control sleeve 30 from continuing to rotate outwardly, thereby cooperating with the outer circumferential side of the main valve body 10 to limit the movement distance of the innermost side and the outermost side of the rotating control sleeve 30, and avoid the rotating control sleeve 30 from being dislocated due to excessive rotation, thereby affecting the normal control function.

[0057] Preferably, the second clamping groove 27 is arranged on the outer circumferential side of the bypass pipe 20 and between the main valve body 10 and the water inlet hole 41, between the water inlet hole 41 and the water outlet hole 51, and between the water outlet hole 51 and the second external thread 24, and the second clamping groove 27 is provided with a sealing ring 28 for sealing with the inner side wall of the through groove 31.

[0058] In the embodiment, the through groove 31 is in clearance fit with the outer circumferential side of the bypass pipe 20, and the position between the main valve body 10 and the water inlet hole 41, between the water inlet hole 41 and the water outlet hole 51, and between the water outlet hole 51 and the second external thread 24 is sealed by the three sealing rings 28, and the support of the sealing ring 28 can further reduce the friction and improve the smoothness when the rotary control sleeve 30 rotates along the bypass pipe 20 in the axial direction, thereby achieving a better user experience.

[0059] Preferably, the water inlet hole 41 and the water outlet hole 51 are each provided with four and are uniformly distributed around the circumferential side of the bypass pipe 20, and the positions of the water inlet hole 41 and the water outlet hole 51 are opposite to each other.

[0060] The four water inlet holes 41 and the four water outlet holes 51 can increase the water outlet speed from 2-3L / min to 4-5L / min, thereby providing a better practical experience for the user.

[0061] Preferably, the main valve body 10 is detachably connected with a filter screen 60, the filter screen 60 is provided with a water passing channel 61 penetrating through the middle part and a filter screen structure 62 formed on the side wall, the filter screen structure 62 is arranged on the connecting position between the main waterway 11 and the water inlet cavity 40 to filter the water flow flowing to the water inlet cavity 40 along the water passing channel, one end of the filter screen 60 is provided with a pull-easy part 63 for easy pulling, and in the embodiment, the pull-easy part 63 is in the shape of a Chinese character and is fixed at the end of the filter screen 60.

[0062] The built-in filter screen 60 can effectively filter the impurities in the water flow, protect the downstream structure from being damaged, and the pull-easy part 63 facilitates the user to clean the filter screen 60 regularly to maintain good filtering effect.

[0063] Preferably, the outer circumferential side of the rotary control sleeve 30 is provided with a knurled pattern 34.

[0064] The knurled pattern 34 arranged on the outer circumferential side of the rotary control sleeve 30 can improve the friction and achieve a good anti-skid effect, so that the user can obtain a better hand feeling and improve the user experience.

[0065] The installation process and beneficial effects of the utility model are as follows:

[0066] First, the main valve body 10 is taken out, aligning the opening side of the main waterway 11, placing the sealing gasket 14 and the second nut sleeve 13, tightening the second nut sleeve 13 to press the sealing gasket 14 tightly, then holding the pull part 63 of the filter screen 60 and placing the filter screen 60 through the other opening side of the main waterway 11, so that the filter screen structure 62 blocks the connecting position between the main waterway 11 and the water inlet cavity 40, and the pull part 63 is located close to the opening side of the main waterway 11, then, the sealing ring 28 is placed in the three second clamping grooves 27 in sequence, the rotating control sleeve 30 is inserted into the bypass pipe 20 along the water outlet connector 21 side without the second inner thread 32, until the second inner thread 32 of the rotating control sleeve 30 is in contact with the second outer thread 24, then rotating the rotating control sleeve 30, so that it continues to move inward to the innermost position, the limiting stop ring 26 is placed in the first clamping groove 25, forming the outer limiting of the rotating control sleeve 30, finally, the first nut sleeve 23 is placed through the water outlet connector 21, so that the first inner thread 231 is threadedly locked between the first outer thread 22, completing the overall installation process of the three-way valve.

[0067] In summary, the utility model is simple to install, and the original straight push type control is replaced by the spiral rotating control sleeve 30, so that the water flow control can be easily realized by rotating slightly, and the problem of water leakage is avoided.

[0068] The utility model is described above in conjunction with the drawings, and obviously, the specific implementation of the utility model is not limited by the above mode, as long as various non-essential improvements are adopted by using the method concept and technical scheme of the utility model, or the concept and technical scheme of the utility model is directly applied to other occasions without improvement, which are all within the protection scope of the utility model.
