[0028] Embodiment 5: The embodiment provides a drinking water sterilization and disinfection filter killing device, which further has the following technical features in addition to the technical solutions of the above-mentioned embodiments.

[0029] The sterilization and flow stabilizing assembly 13 further comprises: A flow guide shell 104 is arranged on the upper portion of the flow limiting shell 103, the bottom is formed with a flow guide hole 104a upward, the upper portion is formed with an outflow hole 104b downward, and the flow guide hole 104a is in communication with the outflow hole 104b and coaxially arranged; A flow guide assembly is arranged in the flow guide hole 104a; An upper drainage shell 105 is provided with a drainage pipe 105a and a flow guide pipe 105b perpendicular to each other, and the flow guide pipe 105b is coaxially arranged with the flow guide shell 104; An upper sterilization part 106 is arranged at the end of the flow guide pipe 105b away from the flow guide shell 104; The upper drainage shell 105 has a guide tube 105b located on the upper part of the guide shell 104, and the end of the upper sterilization component 106 is positioned towards the outlet hole 104b.

[0030] In this embodiment, the guide hole 104a is used to receive water discharged from the flow-limiting shell 103. The guide component guides and fully mixes the incoming water before it is discharged through the outlet hole 104b.

The water flowing out of the outlet hole 104b is sterilized a second time by the upper sterilization component 106, thereby ensuring that the water passing through the sterilization and flow stabilization component 13 is well sterilized and sterilized, thus improving the safety of drinking water.

[0032] Example 6: This embodiment provides a sterilization and disinfection filtration device for drinking water, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

An outer flow stabilizer 108 is disposed inside the mixing chamber 101b and coaxially disposed outside the inner flow stabilizer 107, and its height is higher than that of the inner flow stabilizer 107.

The outer flow stabilizer 108 is disposed outside the inner flow stabilizer 107 and forms an inner flow stabilizer chamber 109 between the inner flow stabilizers 107. Water first enters the inner flow stabilizer 107 and flows out through the inner flow stabilizer hole, then enters the inner flow stabilizer chamber 109, and finally flows out of the lower flow stabilizer assembly through the outer flow stabilizer hole. A portion of the water entering the upper part of the inner flow stabilizer 107 is guided by the guide portion on the upper guide cover 110, so that it will not remain in the upper part of the inner flow stabilizer 107, thereby ensuring good water flow. Since the inner flow stabilizer hole and the outer flow stabilizer hole are alternately distributed in the axial and circumferential directions, that is, in a grid-like alternating distribution, the water can be better mixed when passing through, thereby ensuring the stability of the water flow discharged from each part of the outer flow stabilizer 108, and ensuring the sterilization and disinfection effect of the lower sterilization tray 102.

Its upper end extends into the flow limiting groove 103b and forms a support part. The external flow stabilizer sleeve 112 is limited within the flow limiting groove 103b; The inner current stabilizer 113 is disposed inside the outer current stabilizer sleeve 112 and is sleeved on the upper end of the support column 111 and slides in cooperation with the upper end of the support column 111.

The inner flow stabilizing core 113 is arranged to cooperate with the outer flow stabilizing sleeve 112; when the flow increases, the inner flow stabilizing core 113 will move to the upper part of the outer flow stabilizing sleeve 112, thereby increasing the opening of the inner flow stabilizing core 113 and improving the flow of water; when the flow is small, the inner flow stabilizing core 113 is located at the lower part of the outer flow stabilizing sleeve 112, so as to reduce the opening of the inner flow stabilizing core 113 and reduce the flow of water, thereby ensuring good flow and stability of the water under different flow conditions. The water stabilized by the middle flow stabilizing assembly is guided by the flow guide assembly, so that the water discharged from the flow hole 104b is more stable and uniform. The inner flow stabilizing core 113 elastically slides in the outer flow stabilizing sleeve 112 by the elastic flow stabilizing spring 114.

[0040] In the embodiment, the outer support wall 112a allows the outer flow stabilizing sleeve 112 to be better fixed in the flow limiting groove 103b, and the inner support wall 112b is used to limit the inner flow stabilizing core 113, so that the inner flow stabilizing core 113 cannot be separated from the outer flow stabilizing sleeve 112. The outer contour of the inner support wall 112b and the inner flow stabilizing core 113 can be set as a regular polygon structure, so as to prevent the inner flow stabilizing core 113 from rotating. The flow stabilizing gap is used for water to pass through, and the support ribs are arranged to uniformly separate the flow stabilizing gap into a plurality of flow distribution grooves 112c. The number of the flow distribution grooves 112c is equal to the number of edges of the outer wall of the inner flow stabilizing core 113, so that the water discharged from the outer flow stabilizing groove can be uniformly distributed to each flow distribution groove 112c, preventing the water from flowing randomly and affecting the performance of the water flow channel. The upper sealing wall 112d is used to support the flow stabilizing spring 114, so as to prevent the flow stabilizing spring 114 and the inner flow stabilizing core 113 from being separated from the outer support wall 112a.

[0041] Embodiment 9: The embodiment provides a drinking water sterilization and disinfection filter device. In addition to the technical solutions of the above-mentioned embodiments, the device has the following technical features.

[0042] The inner flow stabilizing core 113 comprises: The core body 113a is slidably arranged on the side wall of the inner support wall 112b, and the core body 113a abuts against the inner support wall 112b; A plurality of flow distribution channels 113b are uniformly distributed on the lower end of the core body 113a in a circumferential direction, extend outward from the middle of the end surface of the core body 113a, and the plurality of flow distribution channels 113b are connected to each other at the middle of the core body 113a; A plurality of outer guide edges 113c are arranged in an arc shape on the outer edge of the core body 113a and correspond to each flow distribution channel 113b, and the outer guide edges 113c are in sliding fit with the flow distribution holes 112e; Each flow distribution channel 113b is connected to one flow distribution hole 112e through the outer guide edge 113c, and the contact area between the flow distribution channel 113b and the flow distribution hole 112e increases when the core body 113a moves towards the upper sealing wall 112d.

[0043] In the embodiment, the core body 113a is arranged at the bottom of the flow-limiting groove 103b and covers the flow distribution groove 112c in the flow-limiting shell 103; the number of the flow distribution channels 113b is equal to the number of the flow distribution grooves 112c, and the water flowing out of the flow distribution grooves 112c enters the flow-limiting groove 103b and then flows out through the corresponding flow distribution grooves 112c through the flow distribution of the flow distribution channels 113b at the lower end of the core body 113a; thus, the water flowing through the medium-steady flow assembly is stable and uniform. Meanwhile, the outer guide wing 113c is in sliding fit with the flow distribution hole 112e, and when the core body 113a is displaced upward to the sealing wall 112d, the contact area of the flow distribution channel 113b and the flow distribution hole 112e is increased, thus increasing the opening of the inner steady flow core 113 and improving the water flow, which can ensure the stability of the water flow at any time.

[0044] Embodiment 10: The embodiment provides a drinking water sterilization and disinfection filter device, which has the following technical features in addition to the technical solutions of the above-mentioned embodiments.

[0045] The flow guide assembly comprises: The flow guide core 116 is in the shape of a truncated cone with the cross-sectional area decreasing from one end of the flow-limiting shell 103 to the other end; The plurality of outer flow guide wings 117 are uniformly distributed on the outer wall of the flow guide core 116 and extend along the outer wall contour of the flow guide core 116, and the cross section is in the shape of an arc; each outer flow guide wing 117 is connected by an inclined upper flow guide section 117a and an inclined lower flow guide section 117b, the inclination angle of the upper flow guide section 117a is greater than that of the lower flow guide section 117b, and the inclination angle of the lower flow guide section 117b increases from the outer direction to the flow guide core 116; The flow guide hole 104a is in the shape of a cone with the cross-sectional area decreasing from one end of the flow-limiting shell 103 to the other end, and the flow guide assembly is freely rotatably arranged in the flow guide hole 104a.

[0046] In the embodiment, the flow guide assembly is arranged in the flow guide hole 104a and abuts against the upper sealing wall 112d; in order to ensure smooth rotation of the flow guide assembly, a bearing is arranged on the upper sealing wall 112d, and the flow guide assembly is rotatably arranged on the upper sealing wall 112d through the bearing. The number of the outer flow guide wings 117 is equal to the number of the flow distribution grooves 112c, and the bottoms of adjacent outer flow guide wings 117 are formed with flow guide areas close to the areas of the flow distribution grooves 112c; the outer flow guide wings 117 are in the shape of an arc and are inclined, so that the water entering the flow guide hole 104a pushes the outer guide wings and drives the entire flow guide assembly to rotate, so that the water flowing out of the outflow hole 104b is more stable and uniform. Meanwhile, the flow guide core 116, the outer flow guide wings 117 and the flow guide hole 104a are in the shape of a cone, which better enables the water to be concentrated at the outflow hole 104b, thus facilitating sterilization of the upper sterilization member 106.
