[0028] The valve core body 1 is a metal component integrally cast or integrally machined, which has good corrosion resistance, such as stainless steel, aluminum alloy or copper alloy, etc.

[0029] The valve core body 1 is configured as a conducting side 11 and a sealing side 12 along the circumferential direction thereof.

[0030] In any radial section of the valve core body 1, when the sectional radius of the conducting side 11 is R1 and the sectional radius of the sealing side 12 is R2, then R2>R1.

[0032] Please refer to Figure 3The cross-sectional radius of the conductive side 11 is R1, specifically: the straight-line distance between the rotation axis of the valve core body 1 and the most protruding part of the conductive side 11 of the valve core body 1 at the radial cross-section (this case is for the solid part of the conductive side 11 of the valve core body 1); or the straight-line distance between the rotation axis of the valve core body 1 and the most protruding part of the imaginary supplementary surface 112 of the conductive side 11 of the valve core body 1 at the open fluid medium passage 111 (this case is for the hollow part of the conductive side 11 of the valve core body 1); wherein the imaginary supplementary surface 112 is specifically: the curved surface feature obtained when the conductive side 11 of the valve core body 1 is smoothly supplemented as a spherical surface at the open fluid medium passage 111.

[0033] The cross-sectional radius of the sealing side 12 is R2, specifically: the straight-line distance between the rotation axis of the valve core body 1 and the most protruding part of the sealing side 12 of the valve core body 1.

[0034] Figure 3 The cross-sectional radius of the conductive side 11 is R1 and the cross-sectional radius of the sealing side 12 is R2 are respectively shown in the solid part of the conductive side 11 of the valve core body 1 and the hollow part of the conductive side 11 of the valve core body 1.

[0035] Please refer to Figure 1 Further, the conductive side 11 of the valve core body 1 has a fluid guiding rib 113 formed inside, which is a rib-shaped protruding feature integrally formed inside the conductive side 11 of the valve core body 1 in this embodiment.

[0036] Further, the valve core member of the electronic water valve of this embodiment further comprises a connecting shaft 2 connected to one side of the valve core body 1 and coaxial with the rotation axis of the valve core body 1, for introducing rotational power to the valve core body 1, which is integrally formed with the valve core body 1 in this embodiment.

[0038] This embodiment also provides an electronic water valve, which comprises the valve core member of the electronic water valve described above.

[0039] Please refer to Figures 4-6 The electronic water valve of this embodiment further comprises a valve body 3.

[0040] The valve body 3 is an integrally formed shell of metal or engineering plastic material, which is used to provide a structural and functional basis for the electronic water valve.

[0041] The valve body 3 is formed with a chamber 31, which is actually the inner cavity of the valve body 3, and the valve body 3 is also formed with liquid medium passages 32 that pass through the inside and outside of the chamber 31. In this embodiment, the liquid medium passages 32 are short pipe-shaped structural features integrally formed on the valve body 3 and passing through the inside and outside of the chamber 31.

[0042] The valve body 3 is formed with a chamber 31, which is actually the inner cavity of the valve body 3, and the valve body 3 is also formed with liquid medium passages 32 that pass through the inside and outside of the chamber 31. In this embodiment, the liquid medium passages 32 are short pipe-shaped structural features integrally formed on the valve body 3 and passing through the inside and outside of the chamber 31.

[0043] The valve core body 1 is accommodated in the chamber 31 of the valve body 3 and can rotate in the chamber 31 of the valve body 3. It can be understood that the rotation of the valve core body 1 is driven by an actuator (not shown in the figure) or a motor (not shown in the figure).

[0044] Since the cross-sectional radius R2 of the sealing side 12 of the valve core body 1 is greater than the cross-sectional radius R1 of the lead-through side 11 of the valve core body 1, when the lead-through side 11 of the valve core body 1 is aligned with the liquid medium passage 32 of the valve body 3, it does not contact the dynamic sealing ring 4, and when the sealing side 12 of the valve core body 1 is aligned with the liquid medium passage 32 of the valve body 3, it contacts and cooperates with the dynamic sealing ring 4; or, when the lead-through side 11 of the valve core body 1 is aligned with the liquid medium passage 32 of the valve body 3, it exerts a smaller pressure on the dynamic sealing ring 4, and when the sealing side 12 of the valve core body 1 is aligned with the liquid medium passage 32 of the valve body 3, it exerts a larger pressure on the dynamic sealing ring 4.

[0045] The valve core component of the electronic water valve and the electronic water valve using the same have the following characteristics in any radial section of the valve core body 1: when the cross-sectional radius of the conducting side 11 is R1 and the cross-sectional radius of the sealing side 12 is R2, then R2>R1, so that when the valve core component is arranged in the electronic water valve, the conducting side 11 of the valve core body 1 is not in contact with the dynamic sealing ring 4 when aligned with the liquid medium passage 32 of the valve body 3, and the sealing side 12 of the valve core body 1 is in contact with the dynamic sealing ring 4 when aligned with the liquid medium passage 32 of the valve body 3; or the conducting side 11 of the valve core body 1 exerts a smaller pressure on the dynamic sealing ring 4 when aligned with the liquid medium passage 32 of the valve body 3, and the sealing side 12 of the valve core body 1 exerts a larger pressure on the dynamic sealing ring 4 when aligned with the liquid medium passage 32 of the valve body 3; in this way, the valve core body 1 does not cause long-term and excessive pressure extrusion on the dynamic sealing ring 4, thereby delaying the irreversible deformation of the dynamic sealing ring 4, and in addition, the sealing side 12 of the valve core body 1 can be in contact with the dynamic sealing ring 4 or exert a larger pressure on the dynamic sealing ring 4 when aligned with the liquid medium passage 32 of the valve body 3, thereby improving the sealing performance of the valve core body 1 at the sealing side 12, thereby reducing the "internal leakage" of the electronic water valve as much as possible, and improving the overall performance, stability and service life of the electronic water valve and the liquid medium passage.

[0046] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
