[0026] 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.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A sterilization and disinfection device for fruit and vegetable beverage production includes a sterilization tank 1, a control mechanism 2 fixedly connected to the top of the sterilization tank 1, and a sterilization mechanism 3 fixedly connected to the top of the sterilization tank 1.

[0029] The control mechanism 2 includes a liquid level sensor 21, an ultraviolet sensor 22, a drain pipe 23, a solenoid valve 24, an outlet pipe 25, and a microcontroller 26. The liquid level sensor 21 is fixedly connected to the top of the sterilization tank 1, and the bottom of the liquid level sensor 21 penetrates through the sterilization tank 1 and is fixedly connected to the inside of the sterilization tank 1. The ultraviolet sensor 22 is fixedly connected to the inner wall of the sterilization tank 1. The drain pipe 23 is fixedly connected to the bottom of the sterilization tank 1. The solenoid valve 24 is fixedly connected to the bottom of the drain pipe 23. The outlet pipe 25 is fixedly connected to the bottom of the solenoid valve 24. The microcontroller 26 is fixedly connected to the front of the surface of the sterilization tank 1. The sterilization tank 1, the drain pipe 23, the solenoid valve 24, and the outlet pipe 25 are connected.

[0030] In this embodiment: a sterilization tank 1 provides a closed space for accommodating fruit and vegetable beverages for sterilization, ensuring the sterilization process takes place in a stable environment and preventing the introduction of external impurities. A liquid level sensor 21 monitors the liquid level of the fruit and vegetable beverages in the sterilization tank 1 in real time, allowing operators to monitor the liquid volume and facilitating efficient production flow planning. This prevents excessively high or low liquid levels from affecting sterilization effectiveness and equipment safety. An ultraviolet (UV) sensor 22 detects the intensity of UV radiation in the sterilization tank 1, ensuring the UV intensity remains within a suitable range for effective sterilization. Simultaneously, the working state of the sterilization mechanism 3 can be adjusted promptly based on changes in UV intensity. After sterilization, a solenoid valve 24 controls the opening and closing of the drain pipe 23, allowing the sterilized fruit and vegetable beverages to be discharged smoothly, achieving automated drainage and improving production efficiency while avoiding the risk of contamination from manual operation. A microcontroller 26, as the control core of the entire device, receives signals from the liquid level sensor 21 and the UV sensor 22, and controls the power of the UV lamp 32 and the opening and closing of the solenoid valve 24 based on these signals, achieving automated control and improving production stability and reliability.

[0031] Specifically, such as Figure 3 As shown, the sterilization mechanism 3 includes a limiting tube 31, several ultraviolet lamps 32, two servo motors 33, a connecting rod 34, a stirring blade 35, a feed inlet 36, and a cover 37. The bottom of the limiting tube 31 is fixedly connected to the bottom of the inner side of the sterilization tank 1.

[0032] Specifically, such as Figure 3 As shown, the top of the limiting tube 31 is fixedly connected to the top of the inner side of the sterilization tank 1, the ultraviolet lamp tube 32 is fixedly connected to the inner side of the limiting tube 31, and two servo motors 33 are respectively bolted to the two sides of the top of the sterilization tank 1. The output end of the bottom of the servo motor 33 passes through the sterilization tank 1 and is rotatably connected to the sterilization tank 1.

[0033] Specifically, such as Figure 3 As shown, the connecting rod 34 is bolted to the output end of the servo motor 33 at the bottom, the stirring blade 35 is welded to the surface of the connecting rod 34, the feed port 36 is opened on the rear side of the top of the sterilization tank 1, and the cover 37 is rotatably connected to the top of the feed port 36.

[0034] In this embodiment: the limiting tube 31 is made of quartz glass, which has extremely high transmittance of ultraviolet light, allowing the ultraviolet light to fully irradiate the fruit and vegetable beverage, ensuring the sterilization effect. At the same time, the limiting tube 31 can fix the position of the ultraviolet lamp tube 32, preventing the lamp tube from shaking or being damaged. The ultraviolet lamp tube 32 emits ultraviolet light controlled by the ultraviolet sensor 22 and the microcontroller 26, using the sterilization effect of ultraviolet light to disinfect the fruit and vegetable beverage, which can efficiently kill microorganisms and ensure the hygiene and safety of the product. The servo motor 33 drives the connecting rod 34 and the stirring blade 35 to rotate, so that the fruit and vegetable beverage flows continuously in the sterilization tank 1, ensuring that the beverage in all parts can be fully irradiated by ultraviolet light, avoiding sterilization dead corners, and improving the uniformity and thoroughness of sterilization. The feed port 36 facilitates the addition of fruit and vegetable beverages into the sterilization tank 1. The cap 37 can keep the tank closed during the sterilization process, preventing external impurities and microorganisms from entering the tank and ensuring the cleanliness of the sterilization environment.

[0035] Specifically, such as Figure 4 As shown, the limiting tube 31 is made of quartz glass material, and a reinforcing ring 4 is bolted to both the bottom and top of the limiting tube 31. The reinforcing ring 4 is bolted to the top and bottom of the ultraviolet lamp tube 32.

[0036] Specifically, such as Figure 5 As shown, a sealing gasket 5 is bolted to the bottom of the cover 37, and the side of the sealing gasket 5 away from the cover 37 contacts the top of the feed inlet 36.

[0037] In this embodiment: the limiting tube 31 is made of quartz glass, which has a very high transmittance of ultraviolet light, allowing the ultraviolet light to fully irradiate the fruit and vegetable beverage, ensuring the sterilization effect. The reinforcing ring 4 is set to enhance the stability of the limiting tube 31 in the sterilization tank 1, preventing the limiting tube 31 from shaking or shifting during equipment operation, ensuring that the ultraviolet lamp tube 32 can work stably, and improving the reliability of the equipment. The sealing gasket 5 is set to ensure the sealing between the cap 37 and the feed inlet 36, further preventing external impurities and microorganisms from entering the sterilization tank 1, and ensuring the hygiene and safety of the fruit and vegetable beverage during the sterilization process.

[0038] Specifically, such as Figure 2 As shown, a protective shell 6 is fixedly connected to the surface of the microcontroller 26, and the surface of the protective shell 6 is coated with an anti-corrosion coating.

[0039] Specifically, such as Figure 3 As shown, a limiting ring 7 is bolted to the bottom of the surface of the sterilization tank 1, and a support frame 8 is bolted to the bottom of the limiting ring 7.

[0040] In this embodiment: by setting a protective shell 6, the microcontroller 26 is protected from the influence of the external environment, such as dust, moisture, and collisions, thus extending the service life of the microcontroller 26. By setting an anti-corrosion coating, the corrosion resistance of the protective shell 6 is enhanced, enabling it to work stably in harsh production environments. By setting a limiting ring 7, the support frame 8 and the sterilization tank 1 can be supported and limited. By setting a support frame 8, the sterilization tank 1 is provided with stable support, ensuring that the equipment will not shake or tilt during operation, thus guaranteeing the safety and stability of production.

[0041] Working Principle: First, the user installs the sterilization tank 1 in a suitable working position. Then, when sterilization of fruit and vegetable beverages is required, the operator opens the cap 37 and pours the beverage into the sterilization tank 1 through the inlet 36. After adding the beverage, the user tightly closes the cap 37 and the inlet 36. Next, the liquid level sensor 21 monitors the liquid level of the beverage in the sterilization tank 1 in real time. Once the beverage is detected, the liquid level sensor 21 sends a signal to the microcontroller 26. Upon receiving the signal, the microcontroller 26 activates the ultraviolet disinfection lamp and the ultraviolet sensor 22. At this time, the ultraviolet lamp 32 emits ultraviolet light, which passes through the limiting tube 31 made of quartz glass to sterilize the beverage in the sterilization tank 1. The ultraviolet sensor 22 continuously monitors the intensity of the ultraviolet light in the sterilization tank 1. If the ultraviolet light is strong, the sensor will detect the ultraviolet light. When the UV intensity is weak, a signal is sent to the microcontroller 26, which then controls the UV lamp to increase its power. When the UV intensity is strong, the microcontroller 26 controls the UV lamp to decrease its power. Then, the user turns on the power and starts the servo motor 33. The servo motor 33 drives the connecting rod 34 and the stirring blade 35 to rotate, causing the fruit and vegetable beverage to flow continuously in the sterilization tank 1, ensuring that the beverage in all parts is fully exposed to UV radiation and avoiding sterilization dead spots. Finally, when the sterilization work is completed, the microcontroller 26 receives signals from the liquid level sensor 21 and the UV sensor 22, and controls the opening and closing of the solenoid valve 24 according to these signals. After the solenoid valve 24 is opened, the sterilized fruit and vegetable beverage can be discharged from the sterilization tank 1 through the drain pipe 23 and the outlet pipe 25 in sequence. The user can then collect the sterilized fruit and vegetable beverage.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
