DETAILED DESCRIPTION
[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0021] Depend on Figure 1-4 The utility model provides a photocatalytic water sterilization device. The left and right side walls of the inner wall of the shell 100 are rotatably connected with a liquid inlet pipe 101, which is convenient for diverting the water body through the liquid inlet pipe 101. The liquid inlet pipe 101 is made of transparent material, which is easy to transmit light. The right side wall of the inner cavity of the shell 100 is fixedly connected with a glass lampshade 102, which is convenient for protecting the photocatalytic lamp 103. The right side wall of the shell 100 is fixedly connected with a photocatalytic lamp 103, which is convenient for providing a light source. The photocatalytic lamp 103 is located in the inner cavity of the glass lampshade 102. The right side of the outer wall of the liquid inlet pipe 101 is evenly provided with a water outlet, which is inclined. The inclined water outlet facilitates pushing the liquid inlet pipe 101 to rotate. A catalytic net 104 is provided on the left side wall of the cavity, which facilitates the reaction and sterilization. The catalytic net 104 is located on the outside of the liquid inlet pipe 101, and the outer wall of the liquid inlet pipe 101 is evenly fixedly connected with a guide plate 105, which facilitates the dispersion and displacement of the water body. The guide plate 105 is located in the inner cavity of the catalytic net 104, and the right side wall of the inner cavity of the shell 100 is fixedly connected with a guide pipe 106, which facilitates the diversion of the water body through the guide pipe 106. The left side wall of the shell 100 is fixedly connected with a liquid inlet 107, which facilitates water intake through the liquid inlet 107. The right side of the outer wall of the shell 100 is fixedly connected with a liquid outlet 108, which facilitates the discharge of the water body through the liquid outlet 108. The liquid inlet 107 and the liquid outlet 108 are both connected to the shell 100.
[0022] In this embodiment: the liquid inlet 107 is connected to the water supply pipe for water supply, the liquid inlet 107 is opened to allow water to enter the inner cavity of the shell 100 through the liquid inlet 107, and then the water flows into the inner cavity of the liquid inlet pipe 101, and then is discharged from the water outlet. The inclined water outlet sprays water to drive the liquid inlet pipe 101 to rotate, and the guide plate 105 is driven to rotate through the liquid inlet pipe 101. The guide plate 105 facilitates the promotion of water flow, moves and breaks up the water flow so that it can fully contact with the catalytic net 104. By turning on the photocatalytic lamp 103 to react with the catalytic net 104, the water body can be sterilized. The water body is diverted through the guide pipe 106 so that the water is fully released from the catalytic net 104, and then the sterilized water body is discharged through the liquid outlet 108, which can make it easy for the device to break up and push the water body to move, and facilitate the water body to fully contact with the catalytic net 104, which is beneficial to improving the sterilization efficiency of the device.
[0023] It should be noted that the photocatalytic lamp 103 is an ultraviolet lamp. Increasing the ultraviolet light emitted facilitates the sterilization of water bodies and is beneficial to improving the sterilization efficiency. The energy of the photocatalytic lamp 103 is used to excite the catalyst coating on the catalytic mesh 104 to produce hydroxyl free radicals ·OH with oxidizing ability to kill microorganisms in the water.
[0024] A reflective tube 109 is fixedly connected to the inner wall of the guide tube 106 , and the reflective tube 109 is used to reflect light. The inner wall of the reflective tube 109 is mirror-like, and the reflective tube 109 is located outside the catalytic mesh 104 .
[0025] In this embodiment: the reflective tube 109 is raised to facilitate reflection of the light passing through the catalytic net 104, so that the reflected light shines on the outer wall of the catalytic net 104, causing the outer wall of the catalytic net 104 to react, which is convenient for sterilizing the water body. It can make the device convenient for reflecting the light, so that both the inner and outer walls of the catalytic net 104 undergo photocatalytic reaction, which is beneficial to improving the sterilization efficiency of the device.
[0026] Fins 110 are evenly and fixedly connected to the outer wall of the liquid inlet pipe 101 , so that the water can push the liquid inlet pipe 101 to rotate and move. The fins 110 are arranged at an angle, and the water outlet is located between the fins 110 .
[0027] In this embodiment: after the water flows out from the water outlet, it will push the fins 110 to rotate, which will facilitate the rotation of the liquid inlet pipe 101. The rotation of the liquid inlet pipe 101 will facilitate the rotation of the guide plate 105, which will facilitate the displacement and dispersion of the water body, so that the water body can fully contact and react with the catalytic net 104, which is beneficial to the sterilization operation.
[0028] The left side of the outer wall of the shell 100 is arranged at an angle, and a debris discharge port 111 is arranged on the lower side of the outer wall of the shell 100 .
[0029] In this embodiment, the left side of the outer wall of the housing 100 is tilted, and the inner wall of the housing 100 is trumpet-shaped, which is convenient for slowing down the flow rate of the water body. Impurities in the water body are precipitated and enter the impurity discharge port 111. The impurity discharge port 111 is opened to facilitate the discharge of impurities, so that the device can easily precipitate impurities and clean impurities generated in the catalytic process in the water, which is beneficial to improving the practicality of the device.
[0030] A detection port 112 is fixedly connected to the left side of the housing 100 , through which sampling and testing of the water body is facilitated, and the detection port 112 is communicated with the housing 100 .
[0031] In this embodiment, opening the detection port 112 facilitates sampling of water, facilitates testing of the water sterilization effect, and facilitates checking whether the device operates normally, which is beneficial to improving the practicality of the device.
