Description

Technical Field

[0001] The utility model belongs to the field of sterilization equipment, and in particular relates to a high-efficiency sterilization component. Background Art

[0002] Currently, household water treatment sterilizers or washing equipment usually use ultraviolet rays for sterilization. Ultraviolet rays can destroy the internal DNA structure of microorganisms and bacteria, making them unable to reproduce normally and then being eliminated. Although ultraviolet rays sterilize and disinfect quickly, their killing effect is not ideal. Therefore, another high-efficiency sterilization component is urgently needed to solve this problem. Utility Model Content

[0003] Based on the content in the background technology, the utility model discloses a high-efficiency sterilization component, which includes a water passage, an ultraviolet lamp and an ozone generating device, wherein the ultraviolet lamp and the ozone generating device are arranged in the water passage.

[0004] Furthermore, the water passage is a cylindrical shell, the ultraviolet lamp and the ozone generating device are installed and fixed in the cylindrical shell, and are respectively arranged on the upper and lower sides of the cylindrical shell. The side of the cylindrical shell is also connected to a water inlet joint and a water outlet joint, and the water inlet joint and the water outlet joint are also distributed on the upper and lower sides of the cylindrical shell.

[0005] Furthermore, the water outlet joint of the cylindrical shell is located at one end close to the ozone generating device, the water outlet joint is connected to a nozzle through a pipeline, a bubbler is built in front of the nozzle, that is, the bubbler is connected to the end of the pipeline, and the water outlet end of the bubbler is connected to the nozzle;

[0006] The bubbler includes a diverter and a water return device. The diverter is provided with a water flow chamber, and the bottom surface of the water flow chamber is provided with multiple water outlets. The water return device is fixedly connected to the opening at the other end of the water flow chamber relative to the bottom surface; a water inlet is provided at the center of the water return device, and the water inlet is communicated with the water flow chamber of the diverter. The water return device is provided with multiple water return grooves around its water inlet, and the multiple water return grooves are arranged around the water inlet, and the inner side surface of the water return groove close to the water inlet is an inclined surface.

[0007] When the bubbler is built into the water pipe, the water flow hits the return water groove of the return water device and then rebounds, mixes and bubbles, then enters the water flow chamber of the diverter from the water inlet of the return water device, and finally is diverted and refined through multiple water outlets; the multiple return water grooves with inclined surfaces are evenly distributed, which can better guide the return water after the collision, so that they can more effectively collide with each other, mix and bubble at the water inlet of the return water device.

[0008] Furthermore, a water-breaking cone is fixedly connected to the center of the inner bottom surface of the water-passing chamber of the diverter, and multiple water outlets of the diverter are arranged around the water-breaking cone. The water-breaking cone located at the center is coaxial with the water inlet of the return device. In this way, when the water flows into the water-passing chamber of the diverter from the water inlet of the return device, the water flow can flow along the conical surface of the water-breaking cone, and the water-breaking cone can better disperse the water flow and force it to flow out evenly from each water outlet of the diverter.

[0009] Furthermore, a plurality of water-breaking blocks are fixedly connected around the upper part of the conical surface of the water-breaking cone. The setting of the water-breaking blocks has the function of cutting and breaking up the water flow, and can pre-cut and break up the water flow entering the water flow chamber of the diverter, thereby ultimately improving the dispersion of the outgoing water flow.

[0010] Preferably, one end of the diverter housing is provided with a thread, and the other end is connected to a mounting block, so that the bubbler can be built into the opening of the handle of the spray head through the mounting block and can be connected to the pipeline joint through the thread.

[0011] In addition to enhancing the flushing force of water, the above-mentioned bubbler can also return water so that the ozone generated by the ozone generating device is evenly mixed here.

[0012] Furthermore, the pipeline is connected to a flushing interface at one end close to the cylindrical shell, so as to facilitate backwashing the inside of the cylindrical shell with pure water from the interface.

[0013] Preferably, the ozone generating device is an ozone generator or an ozone lamp.

[0014] Through the above technical solution, the utility model has at least the following beneficial effects:

[0015] The high-efficiency sterilization component of this application effectively combines an ultraviolet lamp and an ozone generator to effectively sterilize water flowing through the component. The sterilizing water produced by this high-efficiency sterilization component has certain bactericidal and antibacterial effects. When used as a mouthwash for brushing teeth, rinsing the mouth with this sterilizing water after brushing can achieve a significant bactericidal and antibacterial effect. Simply rinsing the mouth multiple times can also achieve a certain degree of sterilization rate.

[0016] In a further solution, the built-in bubbler can not only divert and refine the water flow, improve the water outlet pressure and water flushing effect of the sterilization component, but also has a water return function, which can make the ozone generated by the ozone generator mixed and dispersed evenly here, thereby maximizing the sterilization effect of the ozone generator.

[0029] Example 1

[0030] refer to Figures 1 to 3 A high-efficiency sterilization component includes a water passage 3, an ultraviolet lamp 6 and an ozone generating device 7, wherein the ultraviolet lamp 6 and the ozone generating device 7 are arranged in the water passage 3.

[0031] The water passage 3 is a cylindrical shell. The ultraviolet lamp 6 and the ozone generating device 7 are installed and fixed in the cylindrical shell and are respectively arranged on the upper and lower sides of the cylindrical shell. The ozone generating device 7 is an ozone generator or an ozone lamp. In this specific embodiment, the ozone generating device 7 is an ozone lamp, which is installed and fixed on the lower side of the cylindrical shell. The side of the cylindrical shell is also connected to a water inlet joint 301 and a water outlet joint 302. The water inlet joint 301 and the water outlet joint 302 are also distributed on the upper and lower sides of the cylindrical shell.

[0032] In this specific embodiment, the water outlet joint 302 of the cylindrical shell is located at one end close to the ozone generating device 7, and the water outlet joint 302 is connected to the nozzle 5 through the pipeline 4. The pipeline 4 is also connected to the flushing interface 303 at one end close to the cylindrical shell, so that the inside of the cylindrical shell can be backwashed with pure water from the interface; a bubbler 12 is built in front of the nozzle 5, that is, Figure 3 , the end of the pipeline 4 is connected to a bubbler 12, and the water outlet end of the bubbler 12 is connected to a nozzle 5;

[0033] refer to Figures 4 to 6 The bubbler 12 includes a diverter 1 and a water return device 2. The diverter 1 is provided with a water flow chamber 101, and a plurality of water outlets 102 are provided on the bottom surface of the water flow chamber 101. The water return device 2 is fixedly connected to the opening at the other end of the water flow chamber 101 relative to the bottom surface; a water inlet 201 is provided at the center of the water return device 2, and the water inlet 201 is communicated with the water flow chamber 101 of the diverter 1. The water return device 2 is provided with at least one water return groove 202 around the water inlet 201.

[0034] When the bubbler 12 is built into the water pipe, the water flow hits the water return groove 202 of the water return device 2, rebounds, collides, mixes and bubbles, and then enters the water flow chamber 101 of the diverter 1 from the water inlet 201 of the water return device 2, and finally is diverted and refined through multiple water outlets 102.

[0035] Of course, the bubbler 12 can be built into the handle opening of the nozzle 5, and its specific setting method is as follows: a thread 105 is provided on one end of the diverter 1, and a mounting block 106 is connected to the other end. The bubbler 12 can be built into the handle opening of the nozzle 5 through the mounting block 106, and can be connected to the joint of the water pipeline 4 through the thread 105.

[0036] In this embodiment, reference Figure 4 The water return device 2 is provided with a plurality of water return grooves 202 around its water inlet 201, specifically six. These six water return grooves 202 are arranged around the water inlet 201, and the inner side surfaces of the water return grooves 202 close to the water inlet 201 are inclined surfaces; the plurality of water return grooves 202 with inclined surfaces arranged evenly in this way can better guide the return water after the collision machine rebounds, so that they can more effectively collide with each other at the water inlet 201 of the water return device 2 to mix and generate bubbles.

[0037] refer to Figure 5 and Figure 6 A water-breaking cone 103 is fixedly connected to the center of the inner bottom surface of the water-passing chamber 101 of the diverter 1. The multiple water outlets 102 of the diverter 1 are arranged around the water-breaking cone 103. The water-breaking cone 103 located at the center is coaxial with the water inlet 201 of the return device 2. In this way, when the water flows into the water-passing chamber 101 of the diverter 1 from the water inlet 201 of the return device 2, the water can flow along the conical surface of the water-breaking cone 103. The water-breaking cone 103 can better disperse the water flow and force it to flow out evenly from each water outlet 102 of the diverter 1. A plurality of water-breaking blocks 104 are fixedly connected around the upper part of the conical surface of the water-breaking cone 103. The setting of the water-breaking blocks 104 has the function of cutting and breaking up the water flow. It can pre-cut and break up the water flow entering the water-passing chamber 101 of the diverter 1, and ultimately improve the dispersion of the outflowing water flow.

[0038] The bubbler 12 can not only enhance the flushing force of water, but also return water so that the ozone generated by the ozone generating device 7 is evenly mixed there.

[0039] The ozone generating device 7 in the high-efficiency sterilization component can rely on the strong oxidizing property of ozone to carry out sterilization and disinfection, and has a strong killing effect, but the ozone it generates needs to diffuse in the water to carry out large-scale sterilization. The present application can disperse the ozone evenly in the pipeline 4 and the water channel 3 through the return water effect of the bubbler 12, thereby maximizing the effectiveness of the ozone generating device 7.

[0040] The sterilization effect of the water discharged from the high-efficiency sterilization assembly described in the above embodiment was tested using the following method: (A 1W ultraviolet lamp 6 was selected and kept on during sterilization. A 1W ozone lamp was selected as the ozone generator 7. During sterilization, the ozone lamp was cycled with a frequency of "5 seconds on, 1 second off" to ensure that the ozone content in the water met the ozone content standard of less than 0.08 ppm, thereby achieving the optimal sterilization effect.)

[0041] S1. Connect tap water to the sterilization component water inlet connector 301. After starting sterilization, maintain the water flow rate of the product nozzle 5 at 2.5L / min. The water supply should be continuous during the test.

[0042] S2. Prepare three sterile beakers, each with a capacity of 2 L, numbered A, B, and C. Inject 500 mL of a solution containing 50,000 cfu / mL of E. coli into each beaker.

[0043] S3. Dissolve 6 g of toothpaste in 1500 mL of sterile water and stir continuously until fully dissolved. Keep stirring during the test.

[0044] S4. Take 250 mL of sterilizing water prepared by the sterilization component and inject it into beaker A. After standing for 1 minute, stir and take a sample marked A1. At the same time, take another 250 mL of sterilizing water prepared by the sterilization component and inject it into beaker A. Stir and take samples every 10 minutes and inject 250 mL of sterilizing water. The samples are marked A10, A20, A30, and A40 respectively.

[0045] S5. Take 250 mL of sterilizing water prepared by the sterilization component and inject it into beaker B. After standing for 5 minutes, stir and take a sample, marked as B5. At the same time, take another 250 mL of sterilizing water prepared by the sterilization component and inject it into beaker B. After stirring for 15 minutes, take a sample and mark it as B15.

[0046] S6. Take 250 mL of toothpaste mixed with water and inject it into beaker C. After standing for 1 minute, stir and take a sample and mark it C1. At the same time, take 250 mL of sterilizing water prepared by the sterilization component and inject it into beaker C. Subsequently, stir and take a sample every 10 minutes and inject 250 mL of sterilizing water. The samples are recorded as C10\C20\C30\C40 respectively.

[0047] The test results of the bactericidal effect of the water discharged from the above-mentioned high-efficiency sterilization component are shown in Figure 7 .

[0048] analyze Figure 7 The data is as follows:

[0049] 1. Check the data of sample A to confirm that the sterilizing water produced by the high-efficiency sterilization component of this application has a certain degree of sterilization effect on bacteria. The sterilization rate of the first cup of sterilizing water is about 30%, and the sterilization rate of the second cup of sterilizing water is about 49%;

[0050] 2. Data A1 and B5 were prepared with the same time of adding sterilizing water but different standing times. There was no significant difference in the sterilization data, indicating that sterilizing water has a faster response and a longer duration of sterilization effect.

[0051] 3. Data A1\10 and B5\15 have a total duration of 10 minutes and 15 minutes respectively. During each period, sterilizing water was added twice, but the sterilization effect was the same. This shows that the sterilization effect of sterilizing water is related to the number of times it is used.

[0052] 4. Data A1 and C1 clearly show that toothpaste has a significant bactericidal effect, and the bactericidal effect of the sample C20 can reach that of A30;

[0053] To sum up the above content, the sterilizing water made by the high-efficiency sterilization component product of this application has certain bactericidal and antibacterial effects. When it is used as a mouthwash for brushing teeth, and the mouthwash is rinsed with the sterilizing water after brushing teeth, its bactericidal and antibacterial effects are obvious. Simply rinsing the mouth multiple times can also achieve a certain degree of sterilization rate.
