Abstract
Description
Technical Field
[0001] This utility model relates to the field of sterilization device technology, specifically to a sterilization device with air cooling. Background Technology
[0002] In the field of fluid sterilization, sterilization devices use high-power LEDs, which generate a lot of heat. Therefore, such sterilization devices need to be equipped with corresponding heat dissipation structures to help dissipate heat.
[0003] For example, Chinese utility patent, publication number CN 222172729 U, entitled "An Active Heat Dissipation Sterilization Component", "includes a sterilizer, and a sterilization component is also provided inside the sterilizer. A radiator is provided directly above the sterilization component for heat dissipation on the back of the sterilization component. The sterilization device also includes a heat dissipation channel for internal and external air exchange. The radiator guides the hot air inside the sterilizer to flow out and the cold air outside to flow into the sterilizer, thereby continuously dissipating heat from the sterilization component."
[0004] While this heat dissipation method can remove heat from the sterilization components, when the power of the sterilization lamp is too high, only by increasing the power of the fan accordingly can a considerable heat dissipation effect be achieved. The higher the fan speed, the greater the noise problem may be. Therefore, the applicant has improved the product by adding a heat sink. The heat sink itself can accommodate the heat of the sterilization components and conduct heat quickly, and then rely on the fan for heat dissipation. The heat sink can also be designed with a larger heat dissipation area to achieve a better heat dissipation effect. Utility Model Content

[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] like Figure 1-5 As shown, this utility model provides a technical solution: a sterilization device with air cooling, including a shell 1 with a water inlet and a water outlet, and a heat dissipation component 2 and a sterilization component 3 are also arranged inside the shell 1, wherein the heating surface of the sterilization component 3 is in contact with the heat dissipation surface of the heat dissipation component 2, so that the heat of the sterilization component 3 can be dissipated and eliminated through the heat dissipation component 2.
[0031] Among them, such as Figure 1 As shown, the heat dissipation assembly 2 includes a cold source, which is a fan 21, and a heat sink 22 for heat conduction. The heat sink 22 is made of a metal material with good thermal conductivity, such as aluminum. The heat sink 22 should also have characteristics such as good heat capacity. A chamber 23 is also provided inside the heat sink 22 so that the fan blades of the fan 21 can penetrate deep into the heat sink 22. In addition, such as Figure 1 As shown, the heat dissipation assembly 2 also includes a barrier 24, which is fixedly installed on the inner wall of the housing 1 to block the fluid that needs to be sterilized, preventing the fluid from directly contacting the fan 21 and the sterilization component 3. The barrier 24 is also connected to the housing 1 by a ventilation structure, which allows the hot air inside the housing 1 to be discharged through the ventilation structure to maintain the low temperature effect of the heat dissipation assembly 2. In use, since the heat sink 22 and the heating surface of the sterilization component 3 are in contact with each other, the heat of the sterilization component 3 is introduced into the heat sink 22. The heat sink 22 can accommodate the heat transferred by the sterilization component 3. At this time, the fan blades of the fan 21 can start to directly dissipate heat from the heat sink 22. The hot air cylinder ventilation structure in the housing 1 can exchange with the cold air outside the housing 1, which helps the heat sink 22 to maintain a low temperature to absorb the heat from the heating surface of the sterilization component 3, so that the sterilization component 3 can maintain normal operation.
[0032] Furthermore, such as Figure 1 as well as Figure 4-5 As shown, the housing 1 and the barrier 24 form a water flow zone 5. The housing 1 includes the main outer shell 12, and the upper cover 11 and lower cover 13 fixedly connected at the upper and lower ends of the outer shell 12. The outer shell 12 also has a step 124 in the middle. The top end face of the step 124 is evenly recessed and has multiple sets of water outlet holes 123. The outlet of the water flow zone 5 is connected to the water outlet holes 123, so that the fluid can enter the water flow zone 5 from the upper cover 11 with the water inlet, and then enter the water outlet holes 123 from the water flow zone, and finally flow into the sterilization zone opened in the lower part of the outer shell 12. The inner lining 121 is fixedly installed on the inner wall of the sterilization zone. The sterilization component 3 sterilizes the fluid in the sterilization zone. After the sterilization is completed, the water flows out from the lower cover 13 with the water outlet. The water flow zone 5 and the water outlet holes 123 form a flow channel.
[0033] Furthermore, such as Figure 1As shown, the upper cover 11 is fixedly connected to the outer shell 12 by a snap-fit structure, while the lower cover 13 is fixedly connected to the outer shell 12 by a thread.
[0034] Furthermore, such as Figure 1 as well as Figure 5 As shown, the sterilization component 3 includes a sterilization lamp plate 31 embedded in the inner side of the bottom of the radiator 22. The light emission direction of the sterilization lamp plate 31 is towards the fluid in the sterilization area. The heating surface is located on the bottom of the radiator 22. A glass 32 is also provided directly below the sterilization lamp plate 31. The glass 32 is made of quartz glass or other materials that allow UVC light to pass through. A mounting seat 34 is also sealed along the upper end face of the step 124. The mounting seat 34 is also sealed to the bottom of the radiator 22 to prevent fluid from entering. The mounting seat 34 also has a mounting groove for sealing the glass 32. The mounting seat 34 can be made of rubber or silicone and has good sealing performance.
[0035] Furthermore, such as Figure 1 As shown, the sterilization component 3 also includes a control board 33, which is disposed within the barrier 24 and is electrically connected to the sterilization lamp plate 31.
[0036] Furthermore, the germicidal lamp plate 31 has multiple sets of high-power UVC LED beads, ensuring that the sterilization of the fluid can be completed within seconds, and the back of the germicidal lamp plate 31 (i.e. the heating surface) is made of materials with good heat transfer effect, such as single-sided aluminum substrate or copper substrate.
[0037] Furthermore, such as Figure 3 As shown, the heat sink 22 includes a heat sink 221 and heat sink fins 222 integrally formed around the heat sink 221 to increase the heat dissipation area of the heat sink 22. When the fan 21 blows towards the heat sink 221, it is obstructed and generates radial wind force that sweeps over the heat sink fins 222 to dissipate heat.
[0038] Furthermore, such as Figure 2 As shown, the heat exchange structure includes a ventilation groove 241 that penetrates the barrier 24 and a ventilation hole 122 that penetrates the outer shell 12. The ventilation hole 122 is directed to the ventilation groove 241, allowing hot and cold air to interact inside and outside. A sealing element 4 is also provided between the outer shell 12 and the barrier 24. The sealing element 4 is located on the periphery of the ventilation groove 241 to prevent fluid from spreading along the water flow area 5 into the ventilation groove 241.
[0039] Furthermore, a sealing element 4 is provided between the upper cover 11 and the outer shell 12 for sealing. The sealing element 4 is preferably a sealing ring, but it can also be replaced by sealant or other sealing structures, as long as a good sealing effect can be achieved.
[0040] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
