Abstract
Description
Technical Field
[0001] This utility model relates to the field of sterilization device technology, specifically to a sterilization device with a heat dissipation structure. Background Technology
[0002] Fluid sterilization devices can use ultraviolet lamps to sterilize passing fluids. For example, Chinese utility model patent, publication number CN 222007390 U, entitled "A Device with High Sterilization Efficiency," includes a sterilization device with a sterilization chamber in the middle and channels for fluid entry and exit at the upper and lower ends. A sterilization element is arranged along the upper part of the sterilization device to irradiate the fluid in the sterilization chamber. A flow channel is also formed between the sterilization element and the inner wall of the sterilization device, and the width of the flow channel is smaller than the width of the channel through which the fluid enters the sterilization device.
[0003] The above-mentioned sterilization device uses cold fluid flowing through it to dissipate heat from the sterilization components. However, the sterilization device cannot be used when exposed to hot fluid. Therefore, the applicant has made improvements to this design and created a sterilization device that is suitable for both cold and hot fluids without affecting the heat dissipation effect of the sterilization components. Utility Model Content
[0004] The purpose of this invention is to provide a sterilization device with a heat dissipation structure to solve the above-mentioned technical problems.
[0005] This utility model provides the following technical solution:
[0006] A sterilization device with a heat dissipation structure includes: an upper component with a water inlet and a lower component with a water outlet. The upper component includes an upper outer shell and an upper inner shell that are nested together. A gap is formed between the upper outer shell and the upper inner shell. A sterilization element is disposed in the cavity of the upper inner shell. The cavity of the upper inner shell is used to store cold fluid to dissipate heat from the sterilization element.
[0007] A diversion structure is provided above the upper inner shell corresponding to the water inlet. One outlet of the diversion structure can introduce fluid to the heating surface of the sterilization element, and the other outlet is connected to the gap.
[0008] The upper inner shell is also provided with a water injection hole;
[0009] Cold fluid flows into the diversion structure through the inlet, and the diversion structure introduces part of the fluid into the cavity of the upper inner shell so that part of the cold fluid comes into contact with the heating surface of the sterilization element.
[0010] Hot fluid flows into the diversion structure through the inlet. The outlet of the diversion structure leading to the upper inner shell cavity is closed so that all hot fluid flows into the gap and does not come into contact with the sterilization element. External cold fluid is injected into the upper inner shell cavity through the water injection hole.
[0011] Furthermore, the diversion structure includes a plurality of first protrusions protruding from the upper surface of the upper inner shell, with a first water inlet formed between adjacent first protrusions for introducing fluid into the gap, and a water inlet hole is also provided at the center of the upper inner shell for introducing fluid into the cavity of the upper inner shell.
[0012] Furthermore, the upper end of the first protrusion is sealed to the inner wall of the upper outer shell.
[0013] Furthermore, the lower assembly includes a lower outer shell and a lower inner shell that are connected by an inner and outer shell. The upper surface of the lower outer shell is formed with a second protrusion. A second water passage is formed between adjacent second protrusions. The second water passage communicates with the water outlet of the gap so that fluid is discharged into the cavity of the lower inner shell along the second water passage.
[0014] Furthermore, the upper inner shell is a heat insulation component.
[0015] Furthermore, the sterilization component includes a carrier, a sterilization lamp plate and a light-transmitting plate that are sealed and connected vertically along the inner side of the carrier.
[0016] Furthermore, the germicidal lamp plate is sealed inside the lower end of the upper inner shell.
[0017] Furthermore, the back of the germicidal lamp plate is made of aluminum or copper substrate.
[0018] Furthermore, the light-emitting surface of the germicidal lamp plate is also uniformly distributed with ultraviolet lamp beads, which operate at a UVC ultraviolet irradiation intensity of 30mW / cm2.
[0019] Furthermore, the light-transmitting plate is made of quartz glass or sapphire glass.
[0020] Compared with the prior art, the beneficial effects of this utility model are:
[0021] In this invention, a diversion structure is provided, which can selectively introduce fluid into the heating surface of the sterilizing element. When the fluid is cold, part of it is introduced into the heating surface of the sterilizing element, and the other part is introduced into the gap and discharged into the cavity that the sterilizing element can irradiate. When the fluid is hot, all of it is introduced into the gap and discharged into the cavity that the sterilizing element can irradiate. Meanwhile, the cold fluid is injected into the cavity of the upper component through the water injection hole to dissipate heat from the sterilizing element, thereby ensuring that the sterilizing element can be cooled while being sterilized in the face of both hot and cold fluids.

[0028] 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.
[0029] like Figures 1 to 5As shown, this utility model provides a technical solution: a sterilization device with a heat dissipation structure, including an upper component 1 with a water inlet and a lower component 2 with a water outlet. The upper component 1 includes an upper outer shell 11 and an upper inner shell 12 that are nested together. The lower component 2 includes a lower outer shell 21 and a lower inner shell 22 that are nested together. A sterilization element 3 is provided inside the upper inner shell 12. A cavity is formed in the lower inner shell 22 that communicates with the water outlet of the lower outer shell 21. The upper inner shell 12 and the upper outer shell 11... A gap for fluid flow is provided between them. In addition, a diversion structure is provided on the upper inner shell 12 corresponding to the water inlet. One outlet of the diversion structure is used to introduce the fluid to the heating surface of the sterilizing element 3, and the other outlet is connected to the gap. Therefore, the diversion structure on the upper inner shell 12 can introduce part of the fluid into the heating surface (i.e. the back side) of the sterilizing element 3, and the rest can be discharged through the gap. A channel for guiding the fluid in the gap is provided on the lower outer shell 21, and a water injection hole 124 is also provided on the upper inner shell 12.
[0030] To facilitate heat dissipation from the sterilization component 3, this sterilization device was designed. In the face of both hot and cold fluids, all sterilization devices described in this application can dissipate heat from the sterilization component 3. When facing a cold fluid, the water inlet 124 can be closed (a rubber stopper can be inserted into the water inlet 124). The diversion structure can introduce fluid to the heating surface of the sterilization component 3, and the diversion structure is also connected to the gap. Fluid that does not enter the heating surface of the sterilization component 3 can flow into the gap, and the fluid in the gap flows into the channel in the lower outer casing 21, which is connected to it. When facing a hot fluid… The cold fluid can be first injected into the cavity of the upper inner shell 12 through the water injection hole 124 to ensure contact with the heating surface of the sterilizing element 3. Then, the water injection hole 124 is closed, and the flow diversion structure is used to partially close it to ensure that the cold fluid cannot flow into the cavity of the upper inner shell 12, so that all the hot fluid flows into the gap and then enters the cavity of the lower inner shell 22 from the gap. The above design can use the sterilizing element 3 to sterilize the cold / hot fluid, and can also ensure the heat dissipation of the sterilizing element 3. The heat dissipation of the sterilizing element 3 relies on the direct contact between the cold fluid and the heating surface, which has high heat dissipation efficiency and ideal heat dissipation effect.
[0031] like Figure 2-3 As shown, the diversion structure includes a plurality of first protrusions 121 protruding on the upper end of the upper inner shell 12, a first water inlet 122 formed between the plurality of first protrusions 121, and a water inlet 123 opened at the middle position of the upper inner shell 12, and the upper end of the first protrusions 121 is sealed on the inner wall of the upper outer shell (11).
[0032] Furthermore, the upper inner shell 12 is a heat insulation component.
[0033] In addition, such as Figure 3As shown, a plurality of second protrusions 221 are formed on the upper end of the lower outer shell 21, and a second water passage hole 222 is formed between adjacent second protrusions 221.
[0034] like Figure 4-5 As shown, when fluid enters the diversion structure from the inlet of the upper outer shell 11, if it is a cold fluid, part of the fluid enters the gap through the first water inlet 122, then flows into the second water inlet 222 from the gap, and finally flows into the inner cavity of the lower inner shell 22 through the second water inlet 222, where it is sterilized by the sterilization component 3. If it is a hot fluid, cold fluid is injected into the cavity of the upper inner shell 12 through the water injection hole 124, and then the water injection hole 124 and the water inlet 123 are closed. The cold fluid can only enter the gap through the first water inlet 122, and then enter the cavity of the lower inner shell 22 through the second water inlet 222 for sterilization.
[0035] Furthermore, such as Figure 2-3 As shown, the sterilization component 3 includes a carrier 31, a sterilization lamp plate 32 disposed on the upper part of the carrier 31, and a light-transmitting plate 33 disposed on the lower part of the carrier 31. The ultraviolet lamp emitted by the sterilization lamp plate 32 can pass through the light-transmitting plate 33 and irradiate the cavity of the lower inner shell 22.
[0036] Furthermore, the germicidal lamp plate 32 is sealed inside the lower end of the upper inner shell 12, and both the germicidal lamp plate 32 and the light-transmitting plate 33 are sealed in the carrier 31.
[0037] Furthermore, the back of the germicidal lamp plate 32 is made of copper or aluminum substrate.
[0038] Furthermore, the germicidal lamp plate 32 is evenly distributed with multiple sets of high-power ultraviolet lamp beads. The power of the lamp beads allows them to operate normally with a UVC ultraviolet irradiation intensity of 30mW / cm2. This radiation intensity can generally kill almost 100% of most bacteria in one second, so it can be used for the sterilization of fluids.
[0039] Furthermore, the light-transmitting plate 33 is made of quartz glass or sapphire glass.
[0040] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
