Description

Technical Field

[0001] The utility model relates to the technical field of water purifiers, and particularly relates to an ultraviolet sterilization device for a water purifier. Background Art

[0002] A water purifier, also known as a water purification machine or water quality purifier, is a water treatment device that deeply filters and purifies water quality according to the usage requirements of water. Ultraviolet lamp sterilization, as an important function of the water purifier, can play a role in finally sterilizing and purifying the water quality. Currently, the structure of the ultraviolet sterilization device in the prior art generally has a cylindrical shell, with a water inlet pipe and a water outlet pipe respectively arranged at both ends of the shell. A sterilization lamp is arranged inside the shell, and the water flow is irradiated by the ultraviolet lamp when flowing from one end of the shell to the other end, so as to achieve the purpose of sterilization.

[0003] After retrieval, a utility model patent with the patent document number "CN218345220U" discloses an ultraviolet sterilization device for a water purifier. Through the arrangement of the water inlet pipe, the water outlet pipe and the transparent pipe, the incoming water can pass through the irradiation of the ultraviolet lamp tube twice, extending the time for the incoming water to be irradiated by the ultraviolet lamp, making the sterilization effect better. However, the water flow still moves linearly up and down inside the container, making it difficult to delay the time of the water staying inside the container, resulting in the inability to further improve the sterilization effect. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the defects of the prior art and provide an ultraviolet sterilization device for a water purifier to solve the problems raised in the above background art.

An outer spiral channel plate is fixed on the inner wall of the container. The glass tube passes through the center of the outer spiral channel plate and is closely attached to the outer spiral channel plate. A water outlet pipe is arranged on the surface of the container and above the outer spiral channel plate.

[0006] Further, two top seats are symmetrically fixed on the lower sides of the front and rear ends of the cover body, and two base seats are symmetrically fixed on the upper sides of the front and rear ends of the container. The base seats are closely attached to the lower parts of the top seats. A T-shaped slider is fixed at the lower end of the top seat, and a T-shaped chute is opened at the upper end of the base seat. The T-shaped slider is slidably connected with the T-shaped chute.

[0007] Further, one end of the T-shaped chute is an open end, and the other end of the T-shaped chute is a closed end.

[0008] Furthermore, a cavity is provided inside the top seat. A pull head is provided at the upper end of the top seat. A limiting rod is fixed to the lower end of the pull head. The lower end of the limiting rod movably penetrates through the cavity and the T-shaped slider. An annular boss is fixed to the outside of the limiting rod and is located inside the cavity. A spring is connected between the upper end of the annular boss and the inner top end of the cavity. The spring is located outside the limiting rod. A limiting hole is opened at the bottom of the T-shaped chute, and the limiting rod is inserted into the limiting hole.

[0009] Furthermore, the glass tube is made of quartz glass.

DETAILED DESCRIPTION

[0019] See also Figure 1 - Figure 2 When the lid 2 is covered on the upper end of the container 1, the base 5 and the top seat 6 are displaced, and then the T-shaped slider 7 corresponds to the T-shaped slider 8. In this way, rotating the lid 2 can drive the T-shaped slider 7 to slide into the T-shaped slider 8 in a circular motion, and then abut against the other closed end of the T-shaped slider 8. At this time, the base 5 and the top seat 6 are located on the same vertical line.

[0020] See also Figure 1 - Figure 4 , a cavity is provided inside the top seat 6, a pull head 9 is provided at the upper end of the top seat 6, a limit rod 10 is fixed at the lower end of the pull head 9, the lower end of the limit rod 10 movably passes through the cavity and the T-shaped slider 7, an annular boss 11 located inside the cavity is fixed to the outside of the limit rod 10, a spring 12 is connected between the upper end of the annular boss 11 and the top end of the cavity, the spring 12 is located outside the limit rod 10, a limit hole 13 is opened at the bottom of the T-shaped slide 8, the limit rod 10 is plugged into the limit hole 13, before the T-shaped slider 7 slides into the T-shaped slide 8, the pull head 9 is pulled, and the pull head 9 drives the limit rod 10 and the annular boss 1 1 moves up, the annular boss 11 squeezes the spring 12, and then when the T-shaped slider 7 slides into the T-shaped slot 8, the pull head 9 is released, and the spring 12 pushes the annular boss 11 to move down and reset, and the annular boss 11 drives the limiting rod 10 to move down and insert into the limiting hole 13 to limit the T-shaped slider 7 and the T-shaped slot 8, so as to prevent the cover body 2 from rotating and moving up and down, so as to complete the installation of the cover body 2 and the container 1. On the contrary, to disassemble, pull the pull head 9 to move the limiting rod 10 up and pull out the limiting hole 13, and then reverse the cover body 2 to remove the cover body 2. In this way, the relative threaded connection does not require the cover body 2 and the container 1 to rotate multiple turns, thereby preventing the wires from being entangled.

[0021] See also Figure 6, a first sealing ring 19 is fixedly installed on the outer side of the lower end of the cover body 2, and a second sealing ring 20 is fixedly installed on the lower end of the cover body 2 and outside the first sealing ring 19. The outer wall of the first sealing ring 19 is in close contact with the inner wall of the container 1. An annular groove is formed at the upper end of the container 1. The second sealing ring 20 is inserted into the annular groove and is in close contact with the annular groove. After the cover body 2 is installed on the container 1, the sealing performance between the cover body 2 and the container 1 can be improved through the cooperation of the first sealing ring 19 and the second sealing ring 20.

[0022] Please refer to Figure 1 - Figure 6 , a water inlet pipe 3 is provided on the surface of the cover body 2. An inner cavity 14 communicating with the water inlet pipe 3 is provided inside the cover body 2. An ultraviolet lamp tube 15 is fixedly installed at the top end inside the inner cavity 14. A glass tube 16 is fixedly installed at the lower end of the cover body 2. The lower part of the ultraviolet lamp tube 15 extends into the glass tube 16. An inner spiral channel plate 17 is fixedly installed on the inner wall of the glass tube 16. The ultraviolet lamp tube 15 passes through the center of the inner spiral channel plate 17 and is in close contact with the inner spiral channel plate 17. An outer spiral channel plate 18 is fixedly installed on the inner wall of the container 1. The glass tube 16 passes through the center of the outer spiral channel plate 18 and is in close contact with the outer spiral channel plate 18. A water outlet pipe 4 is provided on the surface of the container 1 and above the outer spiral channel plate 18. The water inlet pipe 3 of the cover body 2 and the water outlet pipe 4 of the container 1 are connected to the water purification pipeline. After the water flow enters the inner cavity 14 from the water inlet pipe 3, it will flow spirally from top to bottom along the inner spiral channel plate 17. The ultraviolet lamp tube 15 is connected to the power supply in the water purifier. When the water flow flows spirally, it will be irradiated by the ultraviolet rays emitted by the ultraviolet lamp tube 15. After the water flow enters the container 1, it will flow spirally from bottom to top along the outer spiral channel plate 18. Since the glass tube 16 is made of quartz glass, the ultraviolet rays can pass through the quartz glass and irradiate the water flow on the outer spiral channel plate 18, so as to perform secondary sterilization, and finally be discharged outside through the water outlet pipe 4. In this way, the water flow flows spirally. Compared with the linear flow, the time for the water flow to flow in the container 1 is increased, and the time for the ultraviolet rays to irradiate the water flow is increased, thereby further improving the sterilization effect.
