Description

Technical Field

[0001] This utility model relates to the technical field of drinking water treatment equipment, specifically a sterilization device for the water outlet of a water vending machine. Background Technology

[0002] Currently, public water vending machines commonly use technologies such as reverse osmosis and ultraviolet irradiation to purify water. However, their nozzles are exposed to the air for extended periods, and residual water droplets easily remain after use, creating a damp environment conducive to microbial growth. This results in secondary contamination of the purified water in the "last centimeter" before it flows out, posing a hygiene and safety hazard. Existing solutions often rely on simple static ultraviolet irradiation, which has blind spots and cannot remove existing scale and biofilm on the nozzle surface, affecting sterilization effectiveness and failing to completely solve the nozzle contamination problem. Therefore, there is an urgent need for a water vending machine nozzle sterilization device that can automatically clean itself, achieve efficient sterilization without blind spots, and intelligently avoid user contact. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a sterilization device for the water outlet of a water vending machine.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a sterilization device for a water dispenser nozzle, comprising a first sleeve, mounting blocks on the top of both sides of the first sleeve, mounting holes in the middle of the mounting blocks, a second sleeve fitted onto the bottom of the first sleeve, the top of the inner wall of the first sleeve being fixedly connected to the top of multiple electric push rods, the bottom output end of the electric push rods being fixedly connected to the top of the second sleeve, and multiple ultraviolet lamp columns arranged circumferentially on the upper end of the inner wall of the second sleeve.

[0005] Preferably, a cleaning component is provided below the ultraviolet lamp column on the inner wall of the second sleeve. The cleaning component includes at least two rings of cleaning brushes arranged vertically. The cleaning brushes are distributed circumferentially along the inner wall of the second sleeve, and the adjacent upper and lower rings of cleaning brushes are staggered in the circumferential direction.

[0006] Preferably, a first rubber scraper is provided at the bottom of the inner wall of the first sleeve.

[0007] Preferably, a scraper is provided at the bottom of the inner wall of the second sleeve.

[0008] Preferably, a second rubber scraper strip is provided on the inner circumference of the scraper.

[0009] Preferably, an infrared sensing device is provided on the side wall of the first sleeve.

[0010] Preferably, the inner wall of the second sleeve is made of polished aluminum plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects: The lifting and lowering movement of the second sleeve, driven by an electric push rod, cleverly coordinates the functions of ultraviolet sterilization and mechanical cleaning. When the second sleeve descends, its internal brushes and scrapers thoroughly clean the surface of the water outlet, followed by all-around sterilization within the enclosed chamber created by the ultraviolet lamp. During the ascent, the brushes wipe the water outlet again, and as it retracts into the first sleeve, the first rubber scraper completes self-cleaning. This entire system, combined with infrared sensing, achieves an intelligent closed loop of "automatic sterilization and protection when unattended, and safe storage and use when occupied," fundamentally solving the risk of secondary contamination of the water outlet and significantly improving the hygiene and safety of the equipment and user peace of mind.

[0013] The components include: 1. First sleeve; 2. Mounting block; 201. Mounting hole; 3. Infrared sensor; 4. Second sleeve; 5. Electric push rod; 6. Ultraviolet lamp column; 7. Cleaning brush; 8. Scraper; 9. First rubber scraper; 10. Second rubber scraper. Detailed Implementation

[0014] 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.

[0015] Please see Figure 1 - Figure 3 This utility model provides a technical solution in which mounting blocks 2 are provided on the top of both sides of the first sleeve 1, and mounting holes 201 are provided in the middle of the mounting blocks 2. The bottom of the first sleeve 1 is fitted with a second sleeve 4. The top of the inner wall of the first sleeve 1 is fixedly connected to the top of a plurality of electric push rods 5. The bottom output end of the electric push rod 5 is fixedly connected to the top of the second sleeve 4. A plurality of ultraviolet lamp columns 6 are arranged circumferentially on the upper end of the inner wall of the second sleeve 4.

[0016] The above technical solution involves setting up a second sleeve 4 driven by an electric push rod 5 for lifting and lowering, and arranging ultraviolet lamp columns 6 circumferentially inside it, which realizes the lifting and lowering wrapping of the water outlet and the sterilization by ultraviolet irradiation without dead angles. The structure is compact and highly automated.

[0017] Furthermore, a cleaning component is provided below the ultraviolet lamp column 6 on the inner wall of the second sleeve 4. The cleaning component includes at least two rings of cleaning brushes 7 arranged vertically. The cleaning brushes 7 are distributed circumferentially along the inner wall of the second sleeve 4, and the adjacent upper and lower rings of cleaning brushes 7 are staggered in the circumferential direction.

[0018] At least two rings of cleaning brushes 7 are installed on the inner wall of the second sleeve 4. Through their vertical and circumferentially staggered arrangement, they can form a cross-shaped and thorough cleaning coverage on the outer wall of the water outlet during the lifting and lowering of the second sleeve 4. This effectively removes stubborn scale and biofilm, clearing obstacles for subsequent ultraviolet sterilization and significantly improving the overall cleaning effect.

[0019] Furthermore, a first rubber scraper 9 is provided at the bottom of the inner wall of the first sleeve 1.

[0020] The first rubber scraper 9, located at the bottom of the inner wall of the first sleeve 1, can automatically scrape off dirt and water stains adhering to the brush when the second sleeve 4 drives the cleaning brush 7 to retract, thus realizing the automatic cleaning function of the cleaning brush 7 and effectively preventing the accumulation and cross-contamination of dirt on the brush, thereby maintaining the long-lasting and effective cleaning ability of the cleaning components.

[0021] Furthermore, a scraper 8 is provided at the bottom of the inner wall of the second sleeve 4; a second rubber scraper strip 10 is provided on the inner circumference of the scraper 8.

[0022] The scraper 8, located at the bottom of the inner wall of the second sleeve 4, and the second rubber scraper 10 located on its inner circumference, can contact and scrape off stubborn scale and deposits on the outer wall of the water outlet before the ultraviolet lamp column 6 during the descent of the second sleeve 4, forming a stepped cleaning system with the cleaning brush 7 above. At the same time, when the second sleeve 4 is lowered to its lowest position, the scraper 8 can form a relatively closed sterilization chamber, which can effectively prevent external pollutants from entering and ensure that ultraviolet light energy is efficiently utilized inside the chamber, significantly improving the overall sterilization efficiency and cleanliness.

[0023] Furthermore, an infrared sensing device 3 is provided on the side wall of the first sleeve 1.

[0024] The infrared sensor 3 installed on the side wall of the first sleeve 1 can detect human approach signals in real time. When a user is detected approaching, the signal will be immediately transmitted to the control system, causing the electric push rod 5 to drive the second sleeve 4 to rise and reset, exposing the water outlet for safe use. When the user leaves after a preset time, the system will automatically start the sterilization program, realizing intelligent human-machine interaction and safety protection, effectively avoiding potential harm to personnel from ultraviolet rays, and ensuring the timely execution of the sterilization process.

[0025] Furthermore, the inner wall of the second sleeve 4 is made of polished aluminum plate.

[0026] The inner wall of the second sleeve 4 is made of polished aluminum plate, which forms a highly reflective ultraviolet reflective inner wall. When the ultraviolet lamp column 6 is working, the light can be reflected multiple times in the chamber, which not only eliminates the irradiation dead angle, but also significantly enhances the density and uniformity of ultraviolet energy distribution in the chamber, thereby greatly improving the sterilization efficiency per unit time. At the same time, this material selection also takes into account the durability of the structure and the economical manufacturing cost.

[0027] The working principle of this utility model is as follows: When the infrared sensor 3 detects that no one is around, the control system will activate the electric push rod 5 to push the sleeve 4 downward, so that it extends out of the sleeve 1. During this process, the second rubber scraper 10 on the scraper 8 at the bottom of the inner wall of the sleeve 4 and the cleaning brush 7 arranged circumferentially above will thoroughly scrape and clean the outer wall of the water outlet twice in sequence. When the sleeve 4 is completely lowered, its inner wall forms a sterilization chamber. At this time, the circumferentially arranged ultraviolet lamp column 6 is activated, and the polished aluminum plate inner wall reflects the ultraviolet light in multiple directions, achieving efficient sterilization of the water outlet without dead angles. When the infrared sensor 3 detects that someone is approaching, the control system immediately turns off the ultraviolet lamp column 6 and controls the electric push rod 5 to retract, driving the sleeve 4 to rise and reset. During this process, the cleaning brush 7 cleans the water outlet again and is scraped clean by the rubber scraper 9 at the bottom of the sleeve when it retracts into the sleeve 1, completing the self-cleaning and preparing for the next sterilization cycle.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
