[0069] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0070] like Figures 1 to 7 As shown, this embodiment provides a sterilization device 1 and a water purifier included therein. The sterilization device 1 includes a sterilization shell 10 and a baffle 20 made of transparent material. The sterilization shell 10 has a first open end and a second open end along the axial direction. One end of the baffle 20 is located inside the sterilization shell 10, and the other end extends out of the first open end of the sterilization shell 10 and forms a stepped portion with the first open end. The inner wall surface of the first open end is sealed to the outer wall surface of the baffle 20. The sterilization device 1 also includes a sterilization component 30 and a limiting member 40 connected to the second open end. The limiting member 40 is disposed opposite to the baffle 20 and forms a sterilization chamber 50. The sterilization component 30 is located inside the sterilization chamber 50.

[0071] In this embodiment, the height of the baffle 20 is higher than the height of the sterilization housing 10, so that the baffle 20 can clean the dirt on its surface when the water flows, which helps to ensure the sterilization efficiency and sterilization effect of the sterilization device 1.

[0072] like Figure 2 , Figures 3-7 As shown, the first open end of the sterilization housing 10 has a first extension 101 extending radially inward, which abuts against the outer wall surface of the baffle 20. The outer wall surface of one end of the baffle 20, located inside the sterilization housing 10, has a second extension 201 extending radially outward, which abuts against the inner wall surface of the sterilization housing 10. A first receiving cavity is formed between the first extension 101, the second extension 201, the inner wall surface of the sterilization housing 10, and the outer wall surface of the baffle 20, and a first sealing element 60 is embedded within the first receiving cavity.

[0073] The first accommodating cavity formed by the first extension 101 and the second extension 201 can reliably accommodate the first sealing member 60 and limit the first sealing member 60 to prevent water from flowing into the first accommodating cavity. This also helps to prevent water from flowing into the sterilization cavity 50, thereby helping to ensure the normal use of the sterilization component 30 and the safety of the sterilization device 1.

[0074] Reference Figure 2 , Figures 3-7 It is understood that a second sealing member 70 is provided between the second extension 201, the inner wall surface of the sterilization shell 10, and the top wall of the limiting member 40. The second sealing member 70 is fitted to the inner wall surface of the sterilization shell 10. The second sealing member 70, the baffle 20, and the limiting member 40 form a sterilization chamber 50.

[0075] The second sealing element 70 can further prevent water from flowing into the sterilization chamber 50, which is conducive to ensuring the normal use of the sterilization component 30 and also to ensuring the safety of the sterilization device 1.

[0076] As a preferred embodiment, the first seal 60 and the second seal 70 may be configured as an integral structure and have an adapter hole that is adapted to the second extension 201.

[0077] This configuration integrates the first seal 60 and the second seal 70 into a single unit, resulting in a simple structure, convenient installation, and guaranteed installation reliability of both seals.

[0078] In other alternative embodiments, the first seal 60 and the second seal 70 may be configured as two completely independent structural components, without specific limitations.

[0079] Further reference Figure 2 , Figures 3-7 It is understood that the sterilization component 30 includes LED sterilizer beads, PCB board 302 and power cord 303. The LED sterilizer beads are disposed on PCB board 302 and the power cord 303 is electrically connected to PCB board 302. The limiting member 40 is provided with a connecting hole 401 for the power cord 303 to pass through.

[0080] One end of the power cord 303 is connected to the PCB board 302, and the other end extends through the connecting hole 401 and can be connected to external electrical components, such as a ballast, so as to start the sterilization component 30 and enable the LED sterilizer beads to work normally.

[0081] In this specific embodiment, the PCB board 302 is supported on the top of the limiting member 40.

[0082] like Figures 1-3 , Figures 5-7 It can be understood that the outer wall surface of one end of the baffle 20 extending from the first opening end of the sterilization shell 10 has a rounded corner structure.

[0083] In this embodiment, the transparent material is transparent glass, that is, the baffle 20 is made of transparent glass. In other alternative embodiments, the baffle 20 may also be made of other transparent materials, as long as it does not affect the normal sterilization effect of the sterilization component 30.

[0084] Further reference Figure 2 , Figures 3-7 It is understood that one end of the baffle 20 located inside the sterilization housing 10 is a hollow cylindrical structure with a cavity, and the top of the LED sterilizer lamp bead extends into the cavity.

[0085] The transparent glass is convenient to obtain, which is beneficial to reduce the cost and does not affect the sterilization effect of the sterilization assembly 30. One end of the baffle 20 is provided with a hollow cylindrical structure, and the top of the LED sterilizer lamp bead extends into the cavity, which is beneficial to reduce the space occupied by the sterilization device 1 in the height direction, improve the space utilization rate, and the cavity can also protect the LED sterilizer lamp bead.

[0086] Further, the top of the LED sterilizer lamp bead abuts against the bottom wall of the cavity. In this way, on the one hand, the action path of the LED sterilizer lamp bead is reduced, which is beneficial to ensure that the LED sterilizer lamp bead can better play a sterilization role, thereby being beneficial to ensure the sterilization effect; on the other hand, the top of the LED sterilizer lamp bead abuts against the bottom wall of the cavity of the baffle 20, and the heat of the LED sterilizer lamp bead can be transferred to the baffle 20 made of transparent glass material through heat transfer, and the baffle 20 is further transferred to water, thereby achieving effective heat dissipation.

[0087] As shown in Figures 4-7 In addition to the above-mentioned sterilization device 1, the water purifier also comprises an external shell 2, the external shell 2 has a water inlet 3, and the water purifier also comprises the above-mentioned sterilization device 1, the sterilization device 1 is installed at one end of the external shell 2 away from the water inlet 3, and the baffle 20 and the inner wall of the external shell 2 surround a water storage cavity 4, and the water storage cavity 4 is in communication with the water inlet 3.

[0088] Among them, since the above-mentioned sterilization device 1 has better sterilization efficiency and sterilization effect, the water purifier comprising the above-mentioned sterilization device 1 also has better sterilization efficiency and sterilization effect.

[0089] Further, the external shell 2 comprises a shell body 21 and a central component 22 located in the shell body 21, the central component 22 is coaxially arranged with the shell body 21, the first end of the central component 22 extends out of the shell body 21 along the axis direction, and the water inlet 3 is arranged at the first end of the central component 22. Among them, the second end of the central component 22 along the axis direction is pressed on the top of the sterilization shell 10, and the inner wall of the central component 22 and the baffle 20 surround the water storage cavity 4. The outer wall surface of the sterilization shell 10 is threadedly connected with the inner wall of the shell body 21.

[0090] In this way, the sterilization shell 10 is convenient to connect with the shell body 21, and the overall structure is relatively compact. In addition, the central component 22 acts on the top of the sterilization shell 10, without adversely affecting the baffle 20, which is beneficial to protect the baffle 20, thereby preventing the baffle 20 from being broken or damaged.

[0091] In addition, the outer shell 2 further comprises a top pressing plate 23, which is installed at one end of the shell body 21 close to the water inlet 3. One end of the top pressing plate 23 is pressed against the top of the shell body 21, and the other end extends to the inside of the shell body 21 and circumferentially surrounds the outside of the first end of the central component 22. A third sealing member 24 is clamped between the one end of the top pressing plate 23 and the top of the shell body 21. The inner wall surface of the other end of the top pressing plate 23 is sealingly connected to the outer wall surface of the central component 22. The top pressing plate 23 has a hexagonal shape.

[0092] Further as shown in the drawings, Figures 4-7 the second open end of the sterilization shell 10 has a circumferential flange 102 extending radially outward from the outer wall surface of the sterilization shell 10. The end of the shell body 21 away from the water inlet 3 is pressed against the circumferential flange 102, and a fourth sealing member 5 is clamped between the shell body 21 and the circumferential flange 102. The circumferential flange 102 has a hexagonal shape.

[0093] The provision of the top pressing plate 23 allows the end of the shell body 21 to be connected to the central component 22 more conveniently and ensures the sealing of the shell body 21 and the central component 22. In addition, the hexagonal shape of the top pressing plate 23 also facilitates installation. The shell body 21 is pressed against the circumferential flange 102 of the sterilization shell 10, and no additional structural member is needed to realize the connection of the two, which is conducive to simplifying the overall structure and further improving the overall compactness of the water purifier and ensuring better sealing performance.

[0094] Specifically, as shown in the drawings, Figure 6 and Figure 7 the position where the shell body 21 is connected to the top pressing plate 23 has a first internal thread, and the top pressing plate 23 correspondingly has a first external thread that matches the first internal thread.
