[0031] The water circulation structure for self-cleaning of the sterilizer, as Figures 1 - 3As shown in the figure, it includes a sterilizer box body 50 for sterilizing drinking water. An ultraviolet sterilization tube 10 is installed inside the sterilizer box body 50. A self-cleaning slide base 20 is arranged on the outer wall of the ultraviolet sterilization tube 10. Hollow sleeves 30 are coaxially arranged at both ends of the self-cleaning slide base 20. The two groups of hollow sleeves 30 are connected by a three-way pipe 40. A screw hole 21 along the axial direction is opened at the end of the self-cleaning slide base 20. A detachable inner sleeve 22 is coaxially installed inside the self-cleaning slide base 20. A wiping ring sleeve 23 which is adapted to the outer diameter of the ultraviolet sterilization tube 10 and is in sliding fit is installed inside the detachable inner sleeve 22. The inner diameter of the hollow sleeve 30 is larger than the outer diameter of the ultraviolet sterilization tube 10. A water inlet 31 communicated with the three-way pipe 40 is opened on the inner wall of the hollow sleeve 30. A circulating water pump 41 is connected to the three-way pipe 40. The circulating water pump 41 is externally connected with a water inlet pipe 44 for conveying water through a telescopic corrugated pipe 43. A lead screw 51 which is adapted to the screw hole 21 and is in threaded connection is installed inside the sterilizer box body 50. A drain pipe 53 is connected to the bottom of the sterilizer box body 50. By arranging the self-cleaning slide base 20, the outer wall of the ultraviolet sterilization tube 10 can be automatically cleaned during the sterilization process, the ultraviolet irradiation effect is maintained, and the service life of the equipment is prolonged. The hollow sleeve 30 provides a channel for water circulation. Its inner diameter is designed to be larger than the outer diameter of the ultraviolet sterilization tube 10, ensuring that the water flow can fully contact and clean the outer wall of the sterilization tube. The wiping ring sleeve 23 is adapted to the outer diameter of the ultraviolet sterilization tube 10 and is in sliding fit. With the scouring of the water flow, the dirt on the outer wall of the sterilization tube can be effectively removed, ensuring the uniformity and effectiveness of ultraviolet irradiation. The lead screw 51 is in threaded connection with the screw hole 21 of the self-cleaning slide base 20. By rotating the lead screw, the reciprocating movement of the slide base on the ultraviolet sterilization tube 10 can be controlled, so as to realize the cleaning of different positions. The water inlet pipe 44 can also be externally connected to a drinking water pipe. The drinking water entering the interior passes through the water inlet 31 on the hollow sleeve 30 and the ultraviolet sterilization tube 10, improving the sterilization efficiency.

[0032] Furthermore, the detachable inner sleeve 22 is connected to the self-cleaning slide base 20 by two groups of locking bolts 24. The outer diameter of the detachable inner sleeve 22 is smaller than the inner diameter of the hollow sleeve 30, making the disassembly and installation of the inner sleeve more convenient and fast, and facilitating the user to carry out maintenance, replacement or cleaning.

[0033] It should be noted that the distance between the inner wall of the hollow sleeve 30 and the outer wall of the ultraviolet sterilization tube 10 is 3-10 mm, which not only ensures that the water flow can fully surround and clean the outer wall of the sterilization tube, but also avoids the problems of increased water flow resistance or insufficient cleaning caused by too small a distance. At the same time, the appropriate distance also helps to improve the uniformity of ultraviolet irradiation and further enhance the sterilization effect.

[0034] Specifically, a flange connector 42 that is flange-connected to the telescopic bellows 43 is installed on the water inlet pipe of the circulating water pump 41, making the connection between the water pump and the bellows more firm and reliable, and reducing problems such as water leakage or loosening caused by loose connection.

[0035] Among them, the water inlet pipe 44 passes through the side wall of the sterilizer box body 50 and is connected to the telescopic bellows 43 to improve stability.

[0036] In addition, a servo motor 52 that drives the lead screw 51 to rotate is installed on the outer wall of the sterilizer box body 50. Through the precise control of the servo motor, precise adjustment of the rotation speed and position of the lead screw can be achieved, thereby controlling the up and down movement speed and position of the self-cleaning slide 20 on the ultraviolet sterilization tube 10.

[0037] The working principle of the self-cleaning water circulation structure of this sterilizer:

[0038] First, connect the external water pipe to the water inlet pipe 44; when the sterilizer is started, drinking water enters the telescopic bellows 43 through the water inlet pipe 44, and then the circulating water pump 41 provides power to transport the water to the tee 40;

[0039] The water enters the hollow sleeves 30 at both ends from the tee 40, and through the water inlet 31 on the inner wall of the hollow sleeve 30, the water flow contacts the outer wall of the ultraviolet sterilization tube 10;

[0040] At the same time, the lead screw 51 in the sterilizer box body 50 rotates. Since the lead screw 51 is threadedly connected to the screw hole 21 at the end of the self-cleaning slide 20, the self-cleaning slide 20 is driven to reciprocate on the ultraviolet sterilization tube 10;

[0041] Inside the self-cleaning slide 20, the wiping sleeve 23 in the detachable inner sleeve 22 is in sliding fit with the outer diameter of the ultraviolet sterilization tube 10. Under the action of the water flow scouring and the movement of the self-cleaning slide 20, the dirt on the outer wall of the sterilization tube is effectively removed;

[0042] The wastewater generated during the sterilization process is discharged through the drain pipe 53 at the bottom of the sterilizer box body 50, realizing the automatic cleaning of the outer wall of the ultraviolet sterilization tube 10 during the sterilization process, maintaining the ultraviolet irradiation effect, extending the service life of the equipment, and improving the sterilization efficiency.

[0043] The water inlet pipe 44 can also be externally connected to a drinking water pipe, and the drinking water entering the interior passes through the water inlet 31 on the hollow sleeve 30 and the ultraviolet sterilization tube 10 for drinking water sterilization to improve the sterilization efficiency.

[0044] The above has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present utility model and are not used to limit the present utility model.
