[0038] Furthermore, a first sealing groove 2111 is formed at one end of the valve body 211 close to the limit plate 214, and a first sealing ring 24 is sleeved in the first sealing groove 2111. The first sealing ring 24 is elastically deformed under the pressure of the first sealing groove 2111 and the inner wall of the first opening 112, and the connection between the valve core body and the first opening 112 is sealed by the deformation of the first sealing ring 24. A second sealing groove 2112 is formed at one end of the valve body 211 close to the clamping groove 215, and a second sealing ring 25 is sleeved in the second sealing groove 2112. The second sealing ring 25 is elastically deformed under the pressure of the second sealing groove 2112 and the inner wall of the second opening 113; the connection between the valve core body and the second opening 113 is sealed by the deformation of the second sealing ring 25. In this embodiment, the second sealing groove 2112 and the first sealing groove 2111 are both parallel to each other and are designed as double grooves. The second sealing groove 2112 and the first sealing groove 2111 are both provided with a second sealing ring 25 and a first sealing ring 24 adapted thereto. In this way, the sealing between the valve core assembly 20 and the valve body 10 can be ensured to prevent water from overflowing from the connection between the two.
[0039] The first sealing ring 24 , the second sealing ring 25 , and the retaining spring 23 of the present embodiment are coaxially arranged with the valve body 211 , and coincide with the central axis of the valve body 211 .
[0040] The valve body 10 further comprises a nut connection assembly 12 and an interface connection piece 13. The nut connection assembly 12 is arranged at the water inlet 114, and the interface connection piece 13 is arranged at the second water outlet 116. Specifically, the nut connection assembly 12 comprises a nut 121, a washer 122 and a sleeve 123; one end of the sleeve 123 is connected to the water inlet 114, and the other end is connected to the nut 121; the washer 122 is a quarter washer, and is arranged between the sleeve 123 and the nut 121. An elastic block 1141 is arranged on the outside of the water inlet 114 of the three-way housing 11; a connection slot 1231 is formed on the outside of the sleeve 123, and the elastic block 1141 is sleeved in the connection slot 1231 by elastic force, so that the sleeve 123 is connected to the water inlet 114. The interface connector 13 is preferably a three-part interface connector 13 , and the interface connector 13 includes a self-locking cover 131 and a three-part clamping claw 132 ; the self-locking cover 131 is connected to the second water outlet 116 via the three-part clamping claw 132 .
[0041] The valve body 211 is radially provided with a circular hole slot 2113, and a square slot 2114 is formed at the end of the circular hole slot 2113; the plug 22 includes a columnar block similar to a mushroom shape, which is adapted to the circular hole slot 2113, and a square block is formed at the end of the columnar block, and the square block is adapted to the square slot 2114, and a convex curved surface is formed on the other side of the square block away from the columnar block, and the curved surface can cover the second water outlet 116. That is, the front end of the plug 22 is mushroom-shaped, and the rear end is a square curved columnar shape, which is penetrated in the radial square slot 2114 and the circular hole slot 2113 of the valve body 211. In this way, the plug 22 and the valve core body 21 are fixed, the connection stability between the two is enhanced, and the plug 22 is prevented from shifting and failing during use. The plug 22 is blocked at the second water outlet 116 in the initial state, and the flow channel of the second water outlet 116 is closed at this time. When in use, the valve core body 21 is rotated by turning the handle 212. When it is rotated 90° clockwise, the plug 22 is moved to the upper end position of the horizontal line of the water inlet 114. At this time, the plug 22 deviates from the second water outlet 116, so that the second water outlet 116 is opened, and water will flow out of the second water outlet 116 from the flow channel.
[0042] Furthermore, the valve body 211 has a circumferential tapered angle 2115, which can be set on one side of the valve body 211, or on both opposite sides of the valve body 211, and the tapered angle 2115 is set close to the water inlet 114. The tapered angle 2115 is provided with a plurality of flow holes 2116, and the direction of the flow holes 2116 is perpendicular to the axial direction of the circular hole slot 2113. By setting a conical angle 2115 on the valve body 211, when the mechanical three-way valve is in the open state, that is, the plug 22 deviates from the second water outlet 116, and water can flow through both the first water outlet channel and the second water outlet channel, the water flow entering from the water inlet 114 is diverted and guided through the conical angle 2115, thereby reducing the impact of the water flow on the valve core body 21 and extending the service life; when the mechanical three-way valve is in the closed state, the plug 22 blocks the second water outlet 116 to close the second water outlet channel, and the setting of the flow hole 2116 is conducive to the flow of water through the first water outlet channel, reducing the impact of the water flow on the valve core body 21 and extending the service life.
[0043] The mechanical three-way valve of this embodiment effectively uses two sets of sealing rings between the valve core assembly 20 and the accommodating cavity 111 of the valve body 10 to prevent water from overflowing, and adopts the handle 212 and the buckle to fix the connection, thereby avoiding the movement of the valve core, effectively using the rotating handle 212 to control the movement of the plug 22, and achieving the control of the opening and closing of the second water outlet 116. Not only is the structure more compact, the valve body 10 and the valve core structure are reliable and easy to assemble, but also the size is small, the power consumption is low, the cost is low, and it can meet the use requirements of small spaces, and the adaptability and versatility are good. Although certain components and embodiments of the present application have been illustrated and described, those skilled in the art can think of many modifications and changes (for example, changes in the size, size, structure, shape and proportion of each component, installation arrangement, material use, color, orientation, etc.) without actually departing from the scope and spirit of the claims.
[0044] Finally, it should be noted that the above-mentioned implementation mode is only a preferred embodiment of the present utility model, and cannot be used to limit the scope of protection of the present utility model. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present utility model shall fall within the scope of protection required by the present utility model.
