Description

Technical Field

[0001] This utility model relates to the field of sterilizer technology, specifically an external water tank self-cleaning sterilizer. Background Technology

[0002] Currently, water tanks are often used to store water in industrial production and daily life. However, due to long-term stagnation, the water in the tanks is subject to varying degrees of bacterial and microbial contamination, posing a threat to people's daily water use. To facilitate water treatment, an external water tank self-cleaning and disinfection device is needed.

[0003] Regarding the aforementioned technologies, the applicant believes that when an external water tank self-cleaning sterilizer is in operation, external water first enters the purification tank. The internal filter layer of the purification tank filters impurities from the water. The filtered water is then discharged into the sterilization tank, where ultraviolet (UV) lamps sterilize the water. After sterilization, a water pump transports the water to the water tank for storage. Due to the mineral composition of the water, scale easily accumulates on the surface of the UV lamps after prolonged operation. This scale significantly weakens the penetrating power of UV rays, thus affecting the sterilization effect. Utility Model Content

[0004] The purpose of this invention is to provide an external water tank self-cleaning disinfection device to solve the problem mentioned in the background art that, due to the mineral composition of the water, the surface of the ultraviolet disinfection lamp is prone to scale buildup after long-term operation.

[0029] 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.

[0030] Example 1

[0031] Please see Figures 1 to 5 This embodiment provides a technical solution: an external water tank self-cleaning disinfection device, including a protective box 4 and a maintenance mechanism 8. The maintenance mechanism 8 is located at one end of the protective box 4 and includes a drive motor 801 fixedly connected to the upper part of one end of the protective box 4. The drive motor 801 works based on the principle that a current-carrying conductor moves under the force of a magnetic field. The stator generates a magnetic field, and the coils on the rotor become current-carrying conductors after being energized. Under the action of Ampere force in the magnetic field, torque is generated, causing the rotor to rotate. At the same time, the commutator continuously changes the direction of the coil current to ensure that the rotor rotates continuously in the same direction. When selecting the drive motor 801, the appropriate model should be selected according to the actual needs. All the components required in the drive motor 801 are existing technologies and will not be described in detail below.

[0032] The output end of the drive motor 801 is fixedly connected to the transmission rod 804. The drive motor 801 drives the transmission rod 804 to rotate. Both ends of the transmission rod 804 are provided with driving bevel gears 809. The bottom end of the driving bevel gear 809 is meshed with a driven bevel gear 805. The bottom end of the driven bevel gear 805 is provided with a lead screw 803. The outside of the lead screw 803 is provided with a movable seat 806. The end of the movable seat 806 near the center point inside the protective box 4 is provided with a connecting rod 807. The end of the connecting rod 807 away from the movable seat 806 is provided with a sealing cover 808. Ultraviolet disinfection lamps 15 are evenly arranged at the bottom end of the sealing cover 808. The working principle of the ultraviolet disinfection lamps 15 is based on the inactivation effect of ultraviolet light on microorganisms. Its core lies in destroying the DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) structure in microbial cells through ultraviolet light of a specific wavelength. When selecting it, the appropriate model should be selected according to actual needs. The components required for the above ultraviolet disinfection lamp 15 are all existing technologies and will not be described in detail below.

[0033] The protective box 4 has a drive box 802 at the top inside, and the lead screw 803 and transmission rod 804 are both located inside the drive box 802, which can easily protect the lead screw 803 and transmission rod 804. The protective box 4 has a disinfection box 14 at the bottom inside, which is located directly below the sealing cover 808. The protective box 4 has a door 7 hinged to the outside, which can easily inspect and maintain the equipment inside the protective box 4. There are three sets of ultraviolet disinfection lamps 15, which are symmetrically distributed about the sealing cover 808, which can easily disinfect the water inside the disinfection box 14.

[0034] The overall effect of Embodiment 1 is as follows: The drive motor 801 is started by a control switch, causing the transmission rod 804 to rotate synchronously. This causes the active bevel gear 809 outside the transmission rod 804 to rotate accordingly. Through the transmission of the driven bevel gear 805, the lead screw 803 begins to rotate. As the lead screw 803 rotates, the movable seat 806 drives the connecting rod 807 to rise smoothly along the axis of the lead screw 803, removing the ultraviolet disinfection lamp 15 fixed on the sealing cover 808 from inside the disinfection chamber 14. After the ultraviolet disinfection lamp 15 is removed, it is convenient for staff to clean the scale on it. After cleaning, the drive motor 801 is started in reverse, and the movable seat 806 slowly descends under the drive of the lead screw 803, resetting the ultraviolet disinfection lamp 15 to its initial working position inside the disinfection chamber 14. This improves the ease of maintenance of the equipment and increases the practicality and service life of the device.

[0035] Example 2

[0036] A purification box 5 is located in the middle part of the protective box 4 near the drive motor 801. The purification box 5 has a filter layer 16 inside, which is equipped with an activated carbon layer. It can filter impurities in the water and effectively remove odors and some organic pollutants. A water inlet pipe 9 runs through the purification box 5 near the protective box 4. The water inlet pipe 9 is inserted into the disinfection box 14 to facilitate the discharge of purified water into the disinfection box 14. A water inlet 10 is opened at the top of the purification box 5. A sealing gasket is installed inside the water inlet 10 to facilitate the sealing of the inside of the water inlet 10.

[0037] The effect achieved by the entire embodiment 2 is as follows: external water enters the interior of the purification box 5 through the water inlet 10. By utilizing the operation of the filter layer 16 inside the purification box 5, impurities in the water can be filtered, effectively removing odors and some organic pollutants from the water. The filtered water is then transported to the interior of the disinfection box 14 through the water inlet pipe 9.

[0038] Example 3

[0039] Below the protective box 4, away from the drive motor 801, is an equipment box 11. Inside the equipment box 11 is a water pump 12. The working principle of the water pump 12 is as follows: the impeller is driven to rotate at high speed by the internal motor. Centrifugal force is used to throw the water in the center of the impeller to the edge, so that a low-pressure area is formed in the center. The water in the disinfection box 14 enters the center of the impeller through the suction pipe 13 under atmospheric pressure. It is given kinetic energy by the high-speed rotating impeller. After being guided by the volute, it is converted into pressure energy and then transported to the main body of the water storage tank 2 along the water delivery pipe 6. When selecting the pump, the appropriate model should be selected according to the actual needs. All the components required in the water pump 12 are existing technologies and will not be described in detail below.

[0040] The water pump 12 is provided with a suction pipe 13 at its input end. The end of the suction pipe 13 away from the water pump 12 is inserted into the interior of the disinfection box 14. The water pump 12 is provided with a water delivery pipe 6 at its output end. The end of the water delivery pipe 6 away from the water pump 12 is provided with a water storage tank body 2. The top of the water storage tank body 2 is provided with a tank cover 1. A drain pipe 3 is provided through one side inside the water storage tank body 2.

[0041] The effect achieved by the entire embodiment 3 is as follows: by using the operation of the water pump 12, the water inside the disinfection box 14 can be transported to the water storage tank body 2 for storage through the water suction pipe 13 and the water delivery pipe 6.

[0042] Working principle: First, connect the power supply. External water enters the purification box 5 through the water inlet 10. The filter layer 16 inside the purification box 5 can filter impurities in the water, effectively removing odors and some organic pollutants. The filtered water is then transported to the disinfection box 14 through the water inlet pipe 9.

[0043] Secondly, the ultraviolet disinfection lamp 15 is activated by the control switch. The ultraviolet disinfection lamp 15 emits ultraviolet rays of a specific wavelength, which directly act on the DNA and RNA structure of bacteria and viruses in the water, destroying their genetic material and causing them to lose their ability to reproduce and infect. This effectively kills various pathogenic microorganisms. After disinfection, the water pump 12 is used to transport the water inside the disinfection tank 14 to the water storage tank 2 for storage through the water suction pipe 13 and the water delivery pipe 6.

[0044] Finally, the drive motor 801 is started using the control switch. The drive motor 801 drives the transmission rod 804 to rotate synchronously, causing the driving bevel gear 809 outside the transmission rod 804 to rotate accordingly. Through the transmission of the driven bevel gear 805, the lead screw 803 begins to rotate. As the lead screw 803 rotates, the movable seat 806 drives the connecting rod 807 to rise smoothly along the axis of the lead screw 803, removing the ultraviolet disinfection lamp 15 fixed on the sealing cover 808 from inside the disinfection box 14. After the ultraviolet disinfection lamp 15 is removed, it is convenient for staff to clean the scale on the ultraviolet disinfection lamp 15. After cleaning, the drive motor 801 is started in reverse, and the movable seat 806 slowly descends under the drive of the lead screw 803, resetting the ultraviolet disinfection lamp 15 to its initial working position inside the disinfection box 14. This improves the ease of maintenance of the equipment and increases the practicality and service life of the device.
