Description

Technical Field

[0001] The utility model relates to a water purifier, in particular to a long-acting cyclone type automatic ultraviolet sterilizer. Background Art

[0002] In modern society, as people pay more and more attention to healthy life, the requirements for drinking water quality are getting higher and higher. Although traditional chemical disinfection methods can kill most bacteria and viruses in water, they often contain chemical residues in the water, which poses a potential threat to human health. The long-lasting cyclone automatic ultraviolet sterilizer can effectively avoid this problem. It kills microorganisms in water by physical means without adding any chemical agents, which is safer and more environmentally friendly. In addition, ultraviolet disinfection technology has the advantages of fast sterilization speed, good effect, and no secondary pollution. It can effectively ensure the hygiene and safety of drinking water and plays an important role in improving the quality of life of residents.

[0003] In the prior art, CN202022297501.4 discloses a flowing water ultraviolet sterilization and disinfection unit, which includes a sterilization module and a deep ultraviolet light source module. The sterilization module has a hollow sterilization cavity and is provided with a water inlet and a water outlet connected to the cavity. The cavity is cylindrical, and the inner wall is coated with titanium dioxide or made of polytetrafluoroethylene to form diffuse reflection, so that the ultraviolet light is evenly reflected in the cavity to form a uniform radiation field. This design allows the water flow to be evenly irradiated by ultraviolet rays when passing through the sterilization cavity, thereby improving the sterilization efficiency. At the same time, the deep ultraviolet light source module is equipped with a heat dissipation core, which not only improves the service life of the equipment, but also helps to reduce the size of the equipment, making it easier to install and maintain.

[0004] However, although the above technology has made certain progress in the field of long-lasting cyclone-type automatic ultraviolet sterilizers, there are still some shortcomings. First of all, the sterilization effect of the device may not be thorough enough, and it cannot guarantee the comprehensive killing of all microorganisms in the water. This is due to factors such as water flow velocity, uneven distribution of ultraviolet intensity, or unreasonable design of the sterilization chamber. In addition, in actual use, the user needs to first power on the flowing water ultraviolet sterilization and disinfection unit to activate the ultraviolet light source before turning on the water source for use. After use, the power supply needs to be turned off. This process is relatively cumbersome and affects the user experience. Therefore, in order to further improve the performance and user experience of long-lasting cyclone-type automatic ultraviolet sterilizers, it is necessary to improve and optimize the existing technology.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Embodiment 1: As shown in the figure, a long-acting swirl-type automatic ultraviolet sterilizer includes a shell 1, a water inlet end cover 2, a water outlet end cover 3 and a sterilization mechanism 4. A sterilization chamber 5 is arranged in the shell 1. The water inlet end cover 2 and the water outlet end cover 3 are respectively connected to the two ends of the shell 1 and are both connected to the sterilization chamber 5. The sterilization mechanism 4 is arranged in the shell 1 for sterilizing the medium in the sterilization chamber 5. It also includes an inner cylinder 6 and a water divider 8. The inner cylinder 6 is fixed in the shell 1. The inner cylinder 6 has a water passage chamber 7 connected to the water inlet end cover 2. The water divider 8 is fixed in the shell 1 and is located between the inner cylinder 6 and the sterilization chamber 5. The sterilization mechanism 4 is arranged at the center of the water divider 8. The inner wall of the water divider 8 is provided with a plurality of guide ribs 9 distributed in a vortex shape. A water diversion channel 10 is formed between adjacent guide ribs 9 for causing the water flowing through the water chamber 7 to generate a swirl and enter the sterilization chamber 5.

[0033] Embodiment 2: As shown in the figure, different from Embodiment 1, the sterilization mechanism 4 includes a lampshade 11, an ultraviolet sterilization lamp 12 and a cooling plate 13. The lampshade 11 is fixed in the water divider 8, the ultraviolet sterilization lamp 12 is installed in the lampshade 11, and is used to radiate ultraviolet light into the sterilization chamber 5. The cooling plate 13 is fixed on one side of the lampshade 11, and is used to dissipate the heat generated by the ultraviolet sterilization lamp 12. A gap is left between the cooling plate 13 and the inner cylinder 6.

[0034] In the above structure, the sterilization mechanism 4 adopts a combination design of a lampshade 11, an ultraviolet sterilization lamp 12 and a cooling plate 13. The lampshade 11 can effectively protect the ultraviolet lamp from the impact of water flow and thus prolong its service life. At the same time, the ultraviolet lamp is installed in the lampshade 11 facing the central area of ​​the sterilization chamber 5, which can maximize the sterilization effect; and the cooling plate 13 is fixed on one side of the lampshade 11, leaving a gap between it and the inner tube 6, and uses running water to dissipate the heat generated by the ultraviolet lamp to avoid overheating and affect the sterilization efficiency and life.

[0035] In this embodiment, a limit ring 14 is fixed in the middle section of the water passage chamber 7, a water passage hole 15 is formed in the center of the limit ring 14, a valve core 16 is arranged at the water passage hole 15, and a control component 17 for driving the valve core 16 to block the water passage hole 15 is arranged between the cooling plate 13 and the valve core 16.

[0036] In the above structure, a valve core 16 is provided at the water hole 15 of the limit ring 14, which can control the flow of water and play a control and regulation role. When the water flow needs to be closed, the valve core 16 can block the water hole 15 to achieve the effect of completely cutting off the water flow.

[0037] In this embodiment, the control component 17 includes a valve sleeve 18, a compression spring 19 and a positioning frame 20. One end of the positioning frame 20 abuts against the cooling plate 13, and the other end of the positioning frame 20 abuts against the bottom of the inner tube 6. One end of the valve sleeve 18 is inserted and fixed in the valve core 16, and the compression spring 19 is connected between the positioning frame 20 and the valve sleeve 18.

[0038] The long-lasting cyclone automatic ultraviolet sterilizer is designed with an innovative control component 17 in the part that controls the water flow, including a valve sleeve 18, a compression spring 19 and a positioning frame 20. One end of the positioning frame 20 abuts against the cooling plate 13, and the other end abuts against the bottom of the inner tube 6, providing support and positioning for the entire control component 17. One end of the valve sleeve 18 is inserted and fixed in the valve core 16, and the compression spring 19 is connected between the positioning frame 20 and the valve sleeve 18. This structural design enables the various components of the control component 17 to work together efficiently and move sensitively and reliably.

[0039] When there is no water flowing through, the compression spring 19 will squeeze the valve sleeve 18 so that the valve core 16 blocks the water flow hole 15 at the limit ring 14 in the middle section of the water flow chamber 7, completely cutting off the water flow path and avoiding unnecessary energy consumption. When water is needed to flow through, the water flow will push open the valve core 16, causing it to move and compress the compression spring 19, thereby opening the water flow hole 15. The water flow can smoothly enter the water divider 8 and form a vortex therein, and then be evenly distributed into the sterilization chamber 5 to be sterilized by ultraviolet radiation. In this way, intelligent automatic control of the water flow can be achieved without manual operation, and the degree of automation is high.

[0040] In this embodiment, a control circuit board 21 electrically connected to the ultraviolet sterilization lamp 12 and a reed switch 22 electrically connected to the control circuit board 21 are also provided in the shell 1. A magnet 23 is installed on the valve sleeve 18. When the reed switch 22 senses the magnetic signal of the magnet 23, the ultraviolet sterilization lamp 12 is controlled to be turned on or off through the control circuit board 21.

[0041] When water flows through, the water flow will push open the valve core 16, causing the valve core 16 to move and compress the compression spring 19, while driving the magnet 23 on the valve sleeve 18 to move. At this time, the reed switch 22 electrically connected to the control circuit board 21 senses the change in the magnetic field caused by the displacement of the magnet 23, and will give a power-on signal to the ultraviolet germicidal lamp 12 through the control circuit board 21, so that it turns on and starts sterilization work; conversely, when there is no water flow, under the action of the compression spring 19, the valve core 16 will block the water hole 15, and at the same time the magnet 23 on the valve sleeve 18 returns to its original position, and the reed switch 22 senses that the magnetic field has not changed, thereby giving a power-off signal to the ultraviolet lamp through the control circuit board 21 to turn it off, thereby avoiding unnecessary energy consumption.

[0042] The advantage of this design is that it realizes automatic intelligent control without manual intervention, has a high degree of automation, the components of the control assembly 17 work together efficiently, the switch action is sensitive and reliable, and the ultraviolet lamp is automatically extinguished when there is no water flow, which has the advantages of energy saving and environmental protection. Moreover, the control mechanism is integrated inside the shell 1 to avoid external interference and make the control more precise.

[0043] In this embodiment, an indicator light board 24 electrically connected to the control circuit board 21 is installed on the water inlet end cover 2 , and a light ring 25 is installed on the indicator light board 24 .

[0044] An indicator light board 24 and a light ring 25 are provided at the water inlet end cover 2, which not only play a decorative role, but more importantly, after being electrically connected to the control circuit board 21, the real-time operating status of the system can be intuitively reflected by observing the on and off status. When the light is on, it indicates that the ultraviolet sterilization lamp 12 is running, and when the light is off, it indicates that it has stopped working. This intuitive indication design allows users to understand the working status of the equipment in real time and make corresponding inspections and adjustments according to different states.

[0045] Embodiment 3: As shown in the figure, different from Embodiment 2, the positioning frame 20 includes a central portion and a plurality of support ribs 26 circumferentially fixed on the central portion, the plurality of support ribs 26 are in contact with the cooling plate 13, and water flow spaces are formed between adjacent support ribs 26.

[0046] In the above structure, the central part plays a supporting and positioning role, which is conducive to the installation of the compression spring 19, and the multiple supporting ribs 26 distributed circumferentially not only provide sufficient supporting force for the entire positioning frame 20, but also utilize the water flow space formed between adjacent supporting ribs 26 to provide a channel for water flow, thereby avoiding excessive resistance affecting the sterilization efficiency. When the water flows through the cooling plate 13, it takes away the heat generated by the cooling plate 13, which is conducive to extending the working life of the ultraviolet germicidal lamp 12.

[0047] In this embodiment, a plurality of water-guiding ribs 27 distributed in a spiral shape are fixed to the bottom of the inner tube 6 , and a water flow channel 28 for connecting the water-passing space and the water-dividing channel 10 is formed between adjacent water-guiding ribs 27 .

[0048] In the above structure, the water flow channel 28 formed between the water guiding ribs 27 is connected with the water flow space and the water diversion channel 10, forming the passage of the entire water flow. The vortex-shaped distribution of multiple water guiding ribs 27 enables the water flow to form a rotating vortex before entering the water diversion channel 10, which can not only accelerate the movement of the water flow, but also make the water flow evenly distributed, avoiding the existence of dead corners in local areas and affecting the thoroughness of sterilization. At the same time, the setting of the water guiding ribs 27 also plays a role in accelerating the water flow. The innovative, simple and efficient design of the flow channel realizes efficient rotational movement and uniform distribution of the water flow, greatly improving the sterilization quality.

[0049] In this embodiment, a light guide tube 29 is fixed in the sterilization chamber 5 , a reflector 30 is fixed at the bottom of the light guide tube 29 , and a water outlet hole 31 connected to the water outlet end cover 3 is provided on the reflector 30 .

[0050] In the above structure, the light guide tube 29 cooperates with the reflector 30 to reflect part of the rays, so that the ultraviolet light forms a uniform distribution in the sterilization chamber 5, thereby achieving the purpose of thorough sterilization. At the same time, the water outlet 31 arranged on the reflector 30 is connected with the water outlet end cover 3, providing a smooth outlet for the sterilized water flow. The advantage of this design is that it utilizes the effects of the light guide tube 29 and the reflector 30 to effectively improve the utilization rate and uniform coverage of ultraviolet light, ensuring all-round and efficient sterilization, and the outlet design makes the water flow circulate smoothly, realizing the organic combination of thorough sterilization and circulation efficiency as a whole.

[0051] In this embodiment, the water inlet end cover 2 and the water outlet end cover 3 are respectively provided with detachable plugs 32 .

[0052] When the device is not connected to a water source or is no longer in use, the detachable plug 32 can seal the water inlet and outlet to prevent dust, pollutants or small insects from entering the sterilizer, which helps to keep the sterilization chamber 5 and the ultraviolet irradiation area clean, thereby ensuring the hygiene inside the machine, maintaining the cleanliness of the ultraviolet sterilization lamp 12 and the internal reflective material, and improving the disinfection efficiency. In addition, for use environments that require frequent connection and disconnection of the water source, the detachable plug 32 can be quickly installed and removed, shortening the preparation time for the equipment to be activated again from a stopped state.

[0053] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
