[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This utility model provides a technical solution: an ultraviolet sterilization device for drinking water processing, comprising a stainless steel body 1, wherein a sterilization mechanism for drinking water processing is disposed inside the stainless steel body 1, and the sterilization mechanism includes:

[0026] The cleaning component includes a fixing plate 2 fixedly connected to the inner wall of the left end of the stainless steel body 1. A quartz glass sleeve 201 is provided at the center of the inner wall of the fixing plate 2. Six sets of ultraviolet lamps 202 are provided inside the quartz glass sleeve 201 to emit strong ultraviolet radiation to destroy the DNA structure of microorganisms in the water and achieve sterilization. A connecting ring 203 is provided on the outer side of the quartz glass sleeve 201. A scraper 204 is fixedly connected to the inner wall of the connecting ring 203, and the scraper 204 is tightly fitted to the outer wall of the quartz glass sleeve 201. The connecting ring 203 slides on the outer wall of the quartz glass sleeve 201 through a driving component.

[0027] The stirring assembly includes a support shaft 601 rotatably connected to the inner wall of the right side of the stainless steel body 1. A connecting rod 603 is connected to the outer wall of the support shaft 601. A flap 604 is fixedly connected to the inner side wall of the connecting rod 603. The flap 604 flips inside the stainless steel body 1 to promote water circulation, make the water flow more evenly distributed, and avoid the formation of dead zones and stagnant areas.

[0028] In this embodiment, when drinking water is processed and transported, it is transferred inside the stainless steel body 1 through the inlet 7 and outlet 8. Then, the ultraviolet lamp 202 inside the quartz glass sleeve 201 installed inside the stainless steel body 1 takes effect, especially the ultraviolet (UV) lamp, which can emit strong ultraviolet radiation to destroy the DNA structure of microorganisms in the water, thus playing a bactericidal role. However, during long-term operation, the quartz glass sleeve 201 is prone to scale buildup during the transportation of drinking water. The scraper 204 on the inner wall of the connecting ring 203 slides against the outer wall of the quartz glass sleeve 201, which can physically scrape away the scale. In addition to removing scale and deposits adhering to the surface of the casing, the impact of scale on the light transmittance and ultraviolet disinfection effect of the casing can be reduced, thereby ensuring that ultraviolet light can fully penetrate the casing to achieve the expected sterilization and disinfection effect. At the same time, the flap 604 at the lower end of the connecting rod 603 flips inside the stainless steel body 1, promoting water circulation inside the stainless steel body 1, making the water flow more evenly distributed, helping to avoid the formation of dead zones and stagnant areas, reducing the growth and accumulation of microorganisms and harmful substances, ensuring that the water flow is fully exposed to ultraviolet light, avoiding disinfection blind spots caused by uneven water flow distribution, and helping to enhance the ultraviolet disinfection effect.

[0029] In a preferred embodiment, the driving assembly includes a reciprocating screw 3 disposed at the inner edge of the fixed plate 2. A positioning rod 302 is disposed on the inner wall of the fixed plate 2 on one side of the reciprocating screw 3. A connecting block 301 is slidably connected to the outer wall of the positioning rod 302, and the connecting block 301 is threadedly connected to the reciprocating screw 3. The end of the connecting block 301 near the connecting ring 203 is fixedly connected. The reciprocating screw 3 is driven by a motor, which drives the connecting block 301 to slide along the positioning rod 302, so that one end of the connecting block 301 is fixedly connected to the connecting ring 203 for driving.

[0030] In a preferred embodiment, a sliding shaft 4 is fixedly connected to one end of the connecting block 301 away from the connecting ring 203. When the connecting block 301 slides back and forth along the positioning rod 302, it drives the sliding shaft 4 to perform driving work.

[0031] In a preferred embodiment, a drive shaft 5 is rotatably connected to the inner wall edge of the fixed plate 2. The outer wall of the drive shaft 5 is provided with a first annular groove 501 and a second annular groove 502, and the first annular groove 501 and the second annular groove 502 are symmetrically distributed. A drive gear 6 is fixedly connected to the right end of the drive shaft 5.

[0032] In a preferred embodiment, a transmission gear 602 is fixedly connected to the left end of the support shaft 601. When the sliding shaft 4 is driven, it first moves along the first annular groove 501, driving the drive shaft 5 to rotate on the fixed plate 2. When the sliding shaft 4 moves to the top of the drive shaft 5 and moves again, it will contact the second annular groove 502, thereby driving the drive shaft 5 to rotate on the other side. At the same time, the drive shaft 5 realizes the rotation of the drive gear 6. Since the drive gear 6 and the transmission gear 602 are meshed, the support shaft 601 is rotated.

[0033] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0034] During operation, when drinking water is processed and transported, it is transmitted inside the stainless steel body 1 through the inlet 7 and outlet 8. Then, the ultraviolet lamp 202 inside the quartz glass sleeve 201 set inside the stainless steel body 1 takes effect. In particular, the ultraviolet UV lamp can emit strong ultraviolet radiation, which destroys the DNA structure of microorganisms in the water and plays a bactericidal role. The reciprocating screw 3 is driven by a motor, which drives the connecting block 301 to slide along the positioning rod 302, so that one end of the connecting block 301 is fixedly connected to the connecting ring 203 for driving. The scraper 204 on the inner wall of the connecting ring 203 slides against the outer wall of the quartz glass sleeve 201, which can physically scrape away the scale and deposits attached to the surface of the sleeve.

[0035] When the sliding shaft 4 is driven, it can move along the first annular groove 501, enabling the drive shaft 5 to rotate on the fixed plate 2. When the sliding shaft 4 moves to the top of the drive shaft 5 and moves again, it contacts the second annular groove 502, causing the drive shaft 5 to rotate on the other side. At the same time, the drive shaft 5 enables the drive gear 6 to rotate. Since the drive gear 6 and the transmission gear 602 are meshed, the support shaft 601 rotates, causing the flap 604 at the lower end of the connecting rod 603 to flip inside the stainless steel body 1. This promotes water circulation inside the stainless steel body 1, making the water flow more evenly distributed. This helps to avoid the formation of dead zones and stagnant areas, reduces the growth and accumulation of microorganisms and harmful substances, ensures that the water is fully exposed to ultraviolet light, avoids disinfection blind spots caused by uneven water flow distribution, and helps to enhance the ultraviolet disinfection effect.
