It can be understood that the tank cover 430 is also provided with a hole for the water outlet pipe of the reverse osmosis purifier 300 to extend into. The tank body 420 has a accommodating cavity 421 with an upper opening, and the tank cover 430 is arranged at the opening of the accommodating cavity 421. The bottom of the tank cover 430 is provided with a plug-in portion 432 embedded in the upper end of the accommodating cavity 421. The plug-in portion 432 can be connected to the inner wall of the upper end of the accommodating cavity 421 by interference fit or threaded connection. If interference fit is used to achieve tight fit, the plug-in portion 432 can be made of silicone material. A vertical rod 440 is inserted into the tank cover 430, and the bottom of the vertical rod 440 extends into the accommodating cavity 421. The immersion ultraviolet lamp 500 is connected to the bottom of the vertical rod 440, so that the immersion ultraviolet lamp 500 can be installed in the accommodating cavity 421, and can be installed in the center of the accommodating cavity 421 to perform surrounding sterilization to ensure the sterilization effect.

[0048] Reference Figures 5 to 7In some embodiments of the utility model, a center hole 441 is provided at the center of the vertical rod 440, and the upper end of the immersion type ultraviolet lamp 500 is threadedly connected to the peripheral wall of the lower end of the center hole 441. Specifically, the upper end of the immersion type ultraviolet lamp 500 is provided with a threaded connection shaft 510, and the peripheral wall of the lower end of the center hole 441 is provided with an internal thread section, so as to achieve a threaded connection between the two, and the upper end of the immersion type ultraviolet lamp 500 can be against the end surface of the lower end of the center hole 441, which has a certain sealing effect. In addition, a sealing ring can be provided to improve the sealing effect. The connecting line 511 at the upper end of the immersion type ultraviolet lamp 500 extends upward from the pure water tank 400 along the center hole 441, so that the connecting line 511 of the immersion type ultraviolet lamp 500 is led out to facilitate the connection with an external line to obtain electrical energy.

[0049] In a further embodiment of the utility model, a vent hole 442 is provided on the peripheral wall of the vertical rod 440 inserted into the accommodating cavity 421, and the vent hole 442 is connected to the center hole 441, so that after the pure water tank 400 enters the water, the air can overflow from the vent hole 442 and the center hole 441 to the outside, avoiding the obstruction of the water intake caused by the excessive internal air pressure, and the vent hole 442 is located at the top of the accommodating cavity 421 and will not be easily submerged by the liquid.

[0050] Reference Figure 7 In a further embodiment of the utility model, the tank cover 430 is provided with a threaded hole 431, and the vertical rod 440 is provided with a threaded shaft 443 adapted to the threaded hole 431, and the threaded shaft 443 is threadedly connected to the threaded hole 431, thereby realizing a detachable connection between the tank cover 430 and the vertical rod 440.

[0052] Of course, the present application can also cooperate with the electronic control equipment to realize intelligent control. For example, in order to avoid the overflow of the pure water tank 400, a liquid level sensor can be installed at the high water level in the pure water tank 400. The sensor is associated with an alarm. When the water level in the pure water tank reaches the high water level position, a corresponding alarm will be issued to remind the staff. The staff can choose to shut down or continue to run according to the actual situation. In addition, an anti-overflow switch can be installed at the extreme water level position of the pure water tank 400 (higher than the liquid level sensor). The anti-overflow switch is associated with the main switch of the pure water treatment system through a relay. When the water level reaches the extreme position, the anti-overflow switch is closed to disconnect the main power supply, forcibly shut down the water treatment system, and stop the water supply. Compared with the anti-overflow device of the pure water storage tank in the prior art, a drainage device is set at a predetermined water level, and the drainage outlet is directly placed in the sewer, which will cause bacteria in the sewer to reversely contaminate the pure water tank. The anti-overflow method of the liquid level sensor and the anti-overflow switch is adopted, and there is no discharge pipeline, which avoids reverse contamination through the pipeline. At the same time, it automatically starts and stops, which can reduce the waste of energy and pure water.

[0053] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
