Description

TECHNICAL FIELD

[0001] The utility model relates to water purifier field, especially in a sterilization device of water storage tank. BACKGROUND

[0002] The existing water purifier generally is provided with the water storage tank for storing water, but the water in the water storage tank is easy to breed bacteria, and the user directly drinks not conducive to health.

[0003] In order to solve the above technical problem, one of the existing ways is to directly irradiate the inside of the water storage tank by the ultraviolet lamp, thereby carrying out sterilization to the water contained in the water storage tank, and in order to improve the sterilization effect, part of the water purifier is further provided with a motor and a disturbance rod to disturb the water in the water storage tank.But the ultraviolet lamp in this way is easy to have an irradiation dead angle, and the sterilization effect is poor.The way of disturbing the water in the water storage tank by the motor and the disturbance rod to improve the sterilization effect is easy to leak at the transmission shaft of the motor, and the safety is low.In addition, the water storage tank is easy to yellow and brittle after being irradiated by the ultraviolet lamp for a long time, so the way has higher requirements for the material of the water storage tank. UTILITY MODEL CONTENTS

[0004] The utility model wants to solve the technical problem that the ultraviolet sterilization method in the prior art is easy to have an irradiation dead angle, leading to poor sterilization effect and the water storage tank being easy to yellow and brittle, and provides a sterilization device for water storage tank.

[0005] The utility model solves the above technical problem by the following technical scheme:

[0006] A sterilization device for water storage tank, the sterilization device for water storage tank includes water storage tank, water inlet pipe, water outlet pipe and flow type ultraviolet sterilization assembly;

[0007] The flow type ultraviolet sterilization assembly includes flow part and ultraviolet lamp, the ultraviolet lamp is located at the outside of the flow part, and the inside of the flow part has the first space and the second space that communicate with each other;The water inlet of the water inlet pipe communicates with the inside of the water storage tank, and the water outlet of the water inlet pipe communicates with the first space;The water inlet of the water outlet pipe communicates with the second space, and the water outlet of the water outlet pipe communicates with the inside of the water storage tank;The light outlet of the ultraviolet lamp faces the second space.

[0008] In the scheme, the water in the water storage tank flows into the flow part of the flow type ultraviolet sterilization assembly and is subjected to ultraviolet sterilization treatment, compared with the ultraviolet lamp irradiating the inside of the whole water storage tank, the area to be irradiated by the ultraviolet lamp in the scheme is less, and the irradiation dead angle is not easy to appear, and the energy of ultraviolet is more concentrated, which can improve the sterilization effect.Because the ultraviolet lamp no longer directly irradiates the water storage tank, the water storage tank is not easy to yellow and brittle, and the service life of the water storage tank is improved.

[0009] Preferably, the flow passage includes a first annular plate, a second annular plate, and a partition plate. The first annular plate is sleeved on the outer periphery of the second annular plate. Along the axial direction of the first annular plate, one end of the first annular plate is connected to the partition plate. The second annular plate forms a gap with the partition plate at one end of the first annular plate near the partition plate along the axial direction. The inner sidewall of the first annular plate, the outer sidewall of the second annular plate, and the partition plate form the first space, and the inner sidewall of the second annular plate forms the second space.

[0010] The partition is a light-transmitting plate, and the ultraviolet lamp is located on the side of the partition away from the first ring plate along the axial direction of the first ring plate. The light outlet of the ultraviolet lamp is parallel to the axial direction of the first ring plate.

[0011] In this design, water in the first space flows into the second space through the gap between the second ring plate and the partition. The partition serves two purposes: firstly, it isolates the ultraviolet lamp from the water inside the flow section, thus waterproofing the ultraviolet lamp; secondly, the translucent partition does not restrict the penetration of the ultraviolet light, ensuring that ultraviolet rays can reach the second space and sterilize the water within it.

[0012] Preferably, the projection of the second ring plate onto the ultraviolet lamp along the axial direction of the first ring plate overlaps with the ultraviolet lamp.

[0013] In this scheme, the above-mentioned setup ensures that all water flowing into the second space can be irradiated by ultraviolet lamps, thereby guaranteeing the sterilization effect of ultraviolet light.

[0014] Preferably, the second ring plate is a light-shielding plate.

[0015] In this solution, the light-shielding plate can limit the ultraviolet rays that irradiate the second space from being emitted into the first space through the second ring plate, thereby increasing the energy density of ultraviolet rays in the second space and improving the sterilization effect.

[0016] Preferably, the flow-through ultraviolet sterilization assembly further includes a mounting part, which is disposed on the side of the partition away from the first ring plate in the axial direction and connected to the partition plate. The mounting part has a receiving groove on the side of the first ring plate in the axial direction facing the first ring plate, and the ultraviolet lamp is disposed in the receiving groove.

[0017] In this solution, the mounting section is used to fix the ultraviolet lamp so that the ultraviolet lamp can irradiate the second space directly, thereby improving the sterilization effect.

[0018] Preferably, the flow-through ultraviolet sterilization component is located outside the water storage tank and connected to the bottom plate of the water storage tank.

[0019] In this design, the flow-through ultraviolet sterilization component is installed outside the water storage tank, which prevents the flow-through ultraviolet sterilization component from being immersed in water for a long time and improves the service life of the ultraviolet lamp.

[0020] Preferably, the sterilization device of the water storage tank further includes a driving component, which is located outside the water storage tank. The water inlet pipe includes a first water inlet pipe and a second water inlet pipe. The inlet of the first water inlet pipe is connected to the interior of the water storage tank, the outlet of the first water inlet pipe is connected to the driving component, the inlet of the second water inlet pipe is connected to the driving component, and the outlet of the second water inlet pipe is connected to the first space.

[0021] In this design, the driving component is used to drive water to flow within the inlet pipe, the flow-through ultraviolet sterilization component, and the outlet pipe, thereby achieving water sterilization. The driving component is located outside the water storage tank, preventing prolonged immersion in water, extending its service life, preventing leakage, and improving the safety of the sterilization device within the water storage tank.

[0022] Preferably, the driving component is a diaphragm DC pump.

[0023] In this solution, a diaphragm DC pump is used as the driving component to drive water flow, which can reduce the risk of water leakage from the driving component and improve the safety of the sterilization device in the water storage tank.

[0024] Preferably, the first water inlet pipe is located outside the water storage tank, and the bottom plate of the water storage tank is provided with a through hole, and the water inlet of the first water inlet pipe is connected to the through hole.

[0025] In this solution, the above-mentioned arrangement ensures that all water in the water storage tank can flow into the first inlet pipe, preventing water with a low liquid level from remaining inside the water storage tank and thus preventing sterilization operations, thereby reducing the total number of bacteria in the water.

[0026] Preferably, the inlet of the inlet pipe and the outlet of the outlet pipe are located diagonally opposite each other in the water storage tank.

[0027] In this solution, the above-mentioned settings are used to ensure that the water in the water storage tank can be sterilized by the flow-through ultraviolet sterilization component, so as to reduce the total number of bacteria contained in the water.

[0028] The significant advantages of this invention are as follows: water from inside the storage tank flows into the flow section of the flow-through ultraviolet sterilization component for ultraviolet sterilization. Compared to irradiating the entire interior of the storage tank with an ultraviolet lamp, this design irradiates a smaller area, reducing the risk of irradiating the corners, and the ultraviolet energy is more concentrated, thus improving the sterilization effect. Furthermore, since the ultraviolet lamp no longer directly irradiates the storage tank, it is less prone to yellowing and brittleness, extending the tank's lifespan. Attached Figure Description

[0061] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0062] like Figures 1-4 As shown, this embodiment discloses a sterilization device for a water storage tank 1, which can sterilize the water stored in the water storage tank 1 to ensure the water quality of the water stored in the water storage tank 1. Specifically, the sterilization device for the water storage tank 1 includes a water storage tank 1, a driving component 2, an inlet pipe 3, an outlet pipe 4, and a flow-through ultraviolet sterilization component 5.

[0063] like Figure 2 and Figure 3 As shown, the water storage tank 1 has a water storage space 11. A flow-through ultraviolet sterilization component 5 is connected between the inlet pipe 3 and the outlet pipe 4. The driving component 2 is used to drive the water to flow within the inlet pipe 3, the flow-through ultraviolet sterilization component 5, and the outlet pipe 4 to achieve water sterilization. Specifically, the driving component 2 controls the water in the storage space 11 of the water storage tank 1 to flow into the inlet pipe 3, and then from the inlet pipe 3 into the flow-through ultraviolet sterilization component 5 to sterilize the water. After sterilization, the water flows into the outlet pipe 4, and then flows back into the storage space 11 of the water storage tank 1 via the outlet pipe 4.

[0064] Among them, such as Figure 5 As shown, the flow-through ultraviolet sterilization assembly 5 includes a flow-through section 51, an ultraviolet lamp 52, a mounting section 53, and a fixing section 54.

[0065] Specifically, such as Figure 5As shown, the flow passage 51 includes a first annular plate 511, a second annular plate 512, and a partition plate 513. The first annular plate 511 is sleeved on the outer periphery of the second annular plate 512. The first annular plate 511 and the second annular plate 512 are coaxially arranged, and their axes are parallel to the vertical direction. The partition plate 513 is disposed at one end of the first annular plate 511 and the second annular plate 512 along the axial direction of the first annular plate 511. In this embodiment, the partition plate 513 is disposed at the lower end of the first annular plate 511 and the second annular plate 512. The lower end of the first annular plate 511 extends downward beyond the lower end face of the second annular plate 512. The lower end of the first annular plate 511 is sealed to the partition plate 513, and a gap is formed between the lower end of the second annular plate 512 and the partition plate 513.

[0066] Furthermore, such as Figure 5 As shown, the diameter of the partition 513 is larger than the inner diameter of the first ring plate 511. A sealing element 55 is connected to the lower end of the first ring plate 511. The lower end of the sealing element 55 abuts against the upper end face of the partition 513, and the upper end of the sealing element 55 abuts against the lower end of the first ring plate 511. The sealing element 55 is used to prevent water leakage in the first space 514 and the second space 515 of the flow section 51, thereby improving the sealing performance of the flow-through ultraviolet sterilization assembly 5.

[0067] like Figure 5 As shown, the inner wall of the first ring plate 511, the outer wall of the second ring plate 512, and the partition plate 513 form a first space 514, and the inner wall of the second ring plate 512 forms a second space 515. The first space 514 and the second space 515 are connected. The inlet of the water inlet pipe 3 is connected to the interior of the water storage tank 1, and the outlet of the water inlet pipe 3 is connected to the first space 514. The inlet of the water outlet pipe 4 is connected to the second space 515, and the outlet of the water outlet pipe 4 is connected to the interior of the water storage tank 1. Water in the water storage tank 1 flows into the first space 514 through the water inlet pipe 3, and water in the first space 514 flows into the second space 515 through the gap between the second ring plate 512 and the partition plate 513, and then flows into the water outlet pipe 4 from the second space 515.

[0068] In other alternative embodiments, the first space 514 and the second space 515 may not be nested. The first space 514 and the second space 515 may be two independent spaces in the horizontal or vertical direction, separated by a baffle to form two spaces.

[0069] Furthermore, such as Figure 2 , Figure 3 and Figure 5As shown, the outlet end of the inlet pipe 3 and the inlet end of the outlet pipe 4 are both located inside the water storage tank 1. The bottom plate 12 of the water storage tank 1 is provided with a first flow-through hole 121 and a second flow-through hole 122. The first flow-through hole 121 and the second flow-through hole 122 penetrate the bottom plate 12 vertically. The first flow-through hole 121 communicates with the inlet pipe 3, and the second flow-through hole 122 communicates with the outlet pipe 4. The flow-through ultraviolet sterilization component 5 is located outside the water storage tank 1 and connected to the bottom plate 12 of the water storage tank 1. The first flow-through hole 121 communicates with the first space 514, and the second flow-through hole 122 communicates with the second space 515.

[0070] Furthermore, such as Figure 5 As shown, the bottom plate 12 is also provided with an annular protrusion 13 at one end facing the flow-through ultraviolet sterilization component 5. The annular protrusion 13 is located on the outer periphery of the second ring plate 512, and the inner wall surface of the annular protrusion 13 is connected to the outer wall surface of the second ring plate 512, thereby realizing the connection between the second ring plate 512 and the bottom plate 12.

[0071] Furthermore, such as Figure 5 As shown, in this embodiment, the first ring plate 511 is directly machined on the base plate 12. In other alternative embodiments, the first ring plate 511 can also be assembled with other structures in the flow-through ultraviolet sterilization component 5 and then connected and fixed to the base plate 12.

[0072] like Figure 5 As shown, the ultraviolet lamp 52 is located outside the flow passage 51, with its light outlet facing the second space 515 to sterilize the water within it. Specifically, the mounting part 53 and the ultraviolet lamp 52 are both located on the side of the partition 513 away from the first ring plate 511 along its axial direction (i.e., the lower side of the partition 513). The mounting part 53 is connected to the partition 513, and a receiving groove 531 is provided on the side of the mounting part 53 facing the first ring plate 511 along its axial direction (i.e., the upper end face of the mounting part 53). The ultraviolet lamp 52 is located within the receiving groove 531. In this embodiment, the partition 513 is a light-transmitting plate, and the light outlet of the ultraviolet lamp 52 is parallel to the axial direction of the first ring plate 511. The mounting part 53 is used to fix the ultraviolet lamp 52 so that its light outlet can directly irradiate the second space 515, thereby improving the sterilization effect.

[0073] In this embodiment, the water inside the water tank 1 flows into the flow section 51 of the flow-through ultraviolet sterilization component 5 for ultraviolet sterilization treatment. Compared to the ultraviolet lamp 52 irradiating the entire interior of the water tank 1, the area to be irradiated by the ultraviolet lamp 52 in this embodiment is smaller, less likely to irradiate the four corners, and the energy of the ultraviolet rays is more concentrated, which can improve the sterilization effect. Furthermore, since the ultraviolet lamp 52 no longer directly irradiates the water tank 1, the water tank 1 is less likely to yellow and become brittle, thus improving the service life of the water tank 1.

[0074] The partition 513 serves two purposes: firstly, it isolates the ultraviolet lamp 52 from the water inside the flow section 51, thus waterproofing the ultraviolet lamp 52; secondly, the light-transmitting partition 513 does not restrict the penetration of light from the ultraviolet lamp 52, thereby ensuring that ultraviolet rays can reach the second space 515 and sterilize the water inside the second space 515.

[0075] In addition, the flow-through ultraviolet sterilization component 5 is installed outside the water storage tank 1, which can prevent the flow-through ultraviolet sterilization component 5 from being immersed in water for a long time and improve the service life of the ultraviolet lamp 52.

[0076] Furthermore, such as Figure 5 As shown, the projection of the second ring plate 512 along the axial direction of the first ring plate 511 onto the ultraviolet lamp 52 overlaps with the ultraviolet lamp 52, meaning that all water flowing into the second space 515 can be irradiated by the ultraviolet lamp 52, thereby ensuring the sterilization effect of ultraviolet light.

[0077] Furthermore, in this embodiment, the second ring plate 512 is a light-shielding plate. The light-shielding plate can limit the ultraviolet rays that irradiate the second space 515 from being emitted into the first space 514 through the second ring plate 512, thereby increasing the energy density of ultraviolet rays in the second space 515 and further improving the sterilization effect.

[0078] Furthermore, such as Figure 5 As shown, the fixing part 54 is an annular member and forms an installation space for accommodating the first annular plate 511, the second annular plate 512, the mounting part 53, and the ultraviolet lamp 52. The lower end face of the mounting part 53 abuts against the upper end face of the lower plate 542 of the fixing part 54. The lower plate 542 of the fixing part 54 is also provided with a heat dissipation hole 541, which penetrates the lower plate 542 of the fixing part 54 in the vertical direction. The heat dissipation hole 541 is located directly below the ultraviolet lamp 52 to dissipate the heat generated by the ultraviolet lamp 52.

[0079] like Figures 2-4 As shown, the drive unit 2 is located outside the water storage tank 1. The water inlet pipe 3 includes a first water inlet pipe 31 and a second water inlet pipe 32. The inlet of the first water inlet pipe 31 is connected to the interior of the water storage tank 1, and the outlet of the first water inlet pipe 31 is connected to the drive unit 2. The inlet of the second water inlet pipe 32 is connected to the drive unit 2, and the outlet of the second water inlet pipe 32 is connected to the first space 514. The drive unit 2's location outside the water storage tank 1 prevents it from being submerged in water for extended periods, thus extending its service life, preventing leakage, and improving the safety of the sterilization device in the water storage tank 1.

[0080] In this embodiment, the driving component 2 is a diaphragm DC pump. As the driving component 2 that drives water flow, the diaphragm DC pump can reduce the risk of water leakage and improve the safety of the sterilization device in the water storage tank 1.

[0081] In other alternative implementations, the driver 2 may also be other driving structures capable of achieving the above-described functions.

[0082] Furthermore, such as Figure 2 and Figure 4 As shown, the first water inlet pipe 31 is located outside the water storage tank 1. The bottom plate 12 of the water storage tank 1 is provided with a through hole 123. The inlet of the first water inlet pipe 31 is connected to the through hole 123 so that all the water in the water storage tank 1 can flow into the first water inlet pipe 31, preventing water with a low liquid level from remaining inside the water storage tank 1 and being unable to perform sterilization, thereby reducing the total number of bacteria contained in the water.

[0083] like Figure 3 As shown, the inlet end of the second water inlet pipe 32 is located outside the water storage tank 1 and connected to the drive component 2. The outlet end of the second water inlet pipe 32 passes through the bottom plate 12 of the water storage tank 1 and extends into the interior of the water storage tank 1. All outlet pipes 4 are located inside the water storage tank 1.

[0084] Furthermore, such as Figure 4 As shown, the inlet of the water inlet pipe 3 and the outlet of the water outlet pipe 4 are located diagonally opposite to the water storage tank 1. The inlet of the water inlet pipe 3 is located at the bottom of the water storage tank 1, and the outlet of the water outlet pipe 4 is located near the top of the water storage tank 1. This ensures that the water in the water storage tank 1 can be sterilized by the flow-through ultraviolet sterilization component 5 to reduce the total number of bacteria in the water.
