Description

Technical Field

[0001] This utility model relates to the field of water purifiers, and particularly to the liquid storage of water purifiers. Background Technology

[0002] The flow-through sterilizers used in water purifiers often have a water storage tank. With the continuous introduction of high-flow water purifiers and the use of high-pressure switches in the control system, when the water purifier stops, the pressure in the water system is at the highest value of the high-pressure switch. If the user tries to take water at this time, the initial water intake will be characterized by a spraying sensation due to the excessive pressure in the system, and the flow rate will drop instantly. The user will have to wait for the system to stabilize before the water intake experience improves, resulting in a poor water intake experience. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defect of unstable water pressure in the existing water purifier, and to provide a flow-through sterilizer and a water purifier containing the same.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] A flow-through sterilizer includes a liquid storage container having an inlet and an outlet. The flow-through sterilizer also includes an air bladder having an elastic body disposed inside the liquid storage container and forming a gap with the inner surface of the liquid storage container to allow liquid to flow from the inlet to the outlet.

[0006] In this design, a flexible air bladder is installed inside the liquid storage container. When the outlet is closed and liquid is introduced through the inlet, the air bladder contracts under pressure, increasing the internal pressure. When the outlet is opened for dispensing, the air bladder releases pressure and expands, slowly expelling the liquid from the storage container. This ensures stable dispensing pressure, continuous dispensing, and prevents initial splashing. Furthermore, the air bladder reduces the liquid storage space within the container, thereby minimizing or preventing the growth of bacteria from excessive liquid accumulation.

[0007] Preferably, the airbag also has an inflation part, and an inflation port formed on the inflation part is connected to the airbag body, and the inflation port can be repeatedly opened and closed.

[0008] In this design, the air bladder's inflation port can be repeatedly opened and closed. On the one hand, this allows for replenishing the air bladder with air after the flow-through sterilizer has been used for a period of time, thus maintaining a stable liquid pressure. On the other hand, it allows for adjusting the liquid pressure by adjusting the inflation volume of the air bladder, making the same type of air bladder suitable for different liquid pressures and improving the versatility of the air bladder.

[0009] Preferably, the airbag also has an inflation part, an inflation port formed on the inflation part is connected to the airbag body, the inflation port can be repeatedly opened and closed, the inflation part extends out of the liquid storage container in a sealed manner, and the inflation port is located outside the liquid storage container.

[0010] In this design, the inflation part extends out of the liquid storage container, and the inflation port is located outside the liquid storage container. This allows the airbag to be inflated or replenished from outside the container. Firstly, if the airbag is inflated before being placed into the liquid storage container, the container needs a large opening to accommodate the inflated airbag. In contrast, the flow-through sterilizer in this design allows the airbag to be placed inside the container first and then inflated, simplifying assembly and reducing the structural size requirements of the liquid storage container, thus making the flow-through sterilizer's structure more flexible. Secondly, replenishing the airbag during use is convenient. Thirdly, it avoids contaminating the inside of the liquid storage container during inflation or replenishment.

[0011] Preferably, the airbag also has an inflation part, and an inflation port formed on the inflation part is connected to the airbag body. The inflation port can be repeatedly opened and closed. The flow-through sterilizer also includes a sealing member for sealing the inflation port. The sealing member and the inflation part are detachably connected.

[0012] In this design, the inflation port is closed using a sealing component, ensuring a reliable seal, convenient operation, preventing damage to the inflation unit, and improving durability. The detachable connection between the sealing component and the inflation unit allows for repeated opening and closing of the inflation port.

[0013] Preferably, the airbag also has an inflation part, and the inflation port formed on the inflation part is connected to the airbag body. The inflation port can be repeatedly opened and closed, and the inflation part is fixed to the liquid storage container.

[0014] In this design, the inflation part is fixed to the liquid storage container, which can prevent the airbag from falling off and also stabilize the position of the airbag relative to the liquid storage container, thereby stabilizing the liquid output.

[0015] Preferably, the airbag also has an inflation part, and the inflation port formed on the inflation part is connected to the airbag body. The inflation port can be repeatedly opened and closed. The inflation part is located at the liquid inlet or liquid outlet and extends out of the liquid storage container in a sealed manner from the middle of the liquid inlet or liquid outlet. The inflation port is located outside the liquid storage container.

[0016] In this design, the inflation part extends from the liquid inlet or outlet. On the one hand, the inflation part and the liquid inlet or outlet share an opening on the liquid storage container, eliminating the need for an additional opening on the liquid storage container for the inflation part to extend from, thus making the structure of the liquid storage container more compact. On the other hand, the inflation part extends from the middle of the liquid inlet or outlet, which can disperse the liquid flow at the liquid inlet or outlet, making the liquid inlet or outlet smoother and further preventing spraying.

[0017] Preferably, the airbag also has an inflation part, and an inflation port formed on the inflation part is connected to the airbag body. The inflation port can be repeatedly opened and closed. The liquid storage container has a connected container body and a connecting part. The connecting part protrudes outward from the container body. The liquid inlet or the liquid outlet is formed on the connecting part and connected to the container body. The airbag body is disposed in the container body.

[0018] In this design, the connecting part forming the inlet or outlet protrudes outward from the container body. Firstly, this facilitates the connection between the inlet or outlet and the inlet or outlet pipe; secondly, it facilitates the cleaning and maintenance of the inlet or outlet; and thirdly, it makes the inflation or replenishment of the airbag convenient when the inflation part extends from the middle of the inlet or outlet.

[0019] Preferably, the inflation part is fixed at the liquid inlet or the liquid outlet.

[0020] Preferably, the connecting portion includes a connecting outer ring and a connecting inner ring, the container body is connected to the connecting outer ring, the connecting outer ring is located on the outer periphery of the connecting inner ring and connected to the connecting inner ring, the liquid outlet is formed between the facing surfaces of the connecting outer ring and the connecting inner ring, the air filling portion is sealed to the inner surface of the connecting inner ring and extends from the middle of the connecting inner ring into the liquid storage container.

[0021] Preferably, the liquid storage container has a connected container body and a communicating portion, the liquid inlet and the liquid outlet are formed on the communicating portion and communicate with the container body, the airbag body is disposed in the container body, the container body includes a container cylinder and two container transition portions, the two container transition portions are respectively connected to the two ends of the container cylinder along the length direction of the liquid storage container, the communicating portion is connected to the container transition portion, the inner surface of the container body is a continuous curved surface, and along the length direction of the liquid storage container away from the communicating portion, the size of the container transition portion gradually increases in the direction perpendicular to the length direction of the liquid storage container.

[0022] In this design, the container body is provided with a cylindrical section, which is convenient to process and has a balanced stress distribution. The two ends of the cylindrical section are provided with transition sections. On the one hand, this allows the inner surface of the container body to be a continuous curved surface, which can avoid the formation of stagnant water areas in the container body where the liquid cannot flow out, thus preventing the liquid from deteriorating. On the other hand, the connecting parts that form the inlet and outlet are connected to the transition sections, and the dimensions of the transition sections gradually increase away from the connecting parts, which facilitates the liquid to enter the container body from the inlet or flow out of the container body from the outlet, reducing flow resistance.

[0023] Preferably, the channel for liquid flow in the liquid storage container extends unidirectionally along the length of the liquid storage container, and the liquid inlet and the liquid outlet are respectively located at both ends of the length of the liquid storage container.

[0024] In this design, the liquid can flow unidirectionally along the length of the storage container, which can prevent the formation of stagnant water zones inside the storage container and thus avoid liquid deterioration.

[0025] Preferably, the shape of the outer surface of the airbag body matches the shape of the inner surface of the container body;

[0026] In this design, the gaps between the outer surface of the airbag and the inner surface of the container are more uniform, thereby further enhancing the airbag's ability to stabilize the liquid discharge pressure. When the liquid flow channel within the storage container extends along the length of the container, the airbag's ability to stabilize the liquid discharge pressure is fully utilized.

[0027] Preferably, the liquid storage container is made of a transparent material, and the flow-through sterilizer further includes a sterilizer disposed on the outer periphery of the container cylinder, the sterilizer being a sterilizing lamp, the container cylinder being cylindrical, and the container transition portion being spherical.

[0028] In this design, the light from the sterilization lamp can pass through a transparent liquid storage container to sterilize the liquid inside, ensuring its quality. The sterilization lamp generates heat during use; therefore, mounting it in the cylindrical container provides excellent heat dissipation.

[0029] Preferably, the flow-through sterilizer further includes a sterilizer for sterilizing the liquid entering the liquid storage container; the liquid storage container is made of a transparent material, and the sterilizer is a sterilizing lamp disposed on the outer periphery of the liquid storage container;

[0030] In this solution, the light from the sterilization lamp can pass through the transparent liquid storage container to sterilize the liquid inside, ensuring the quality of the liquid.

[0031] Preferably, the flow-through sterilizer further includes a housing, and the liquid storage container is disposed within the housing.

[0032] In this design, the liquid storage container is housed within the casing, which provides protection for the liquid storage container.

[0033] Preferably, the housing includes a first part and a second part, the second part being fixedly connected to the connection port of the first part along a direction perpendicular to the length of the liquid storage container, and the size of the connection port being larger than the size of the liquid storage container.

[0034] In this design, the size of the connection port of the first part of the shell is larger than the size of the container body. The liquid storage container can be inserted from the connection port of the first part, and then the second part is connected to the first part, which makes the assembly of the flow sterilizer convenient.

[0035] Preferably, the shell is made of opaque material, and the liquid storage container is made of glass.

[0036] In this design, the shell material is opaque, preventing the liquid inside the storage container from deteriorating under normal sunlight. The storage container is made of glass, which is easy to manufacture, has high structural strength, good light transmittance, and good heat dissipation.

[0038] In this design, the sterilization lamp is installed on the side of the mounting component facing the liquid storage container, which shields the lamp to prevent it from shining outside the flow-through sterilizer and causing harm to personnel. The mounting component is made of aluminum with good heat dissipation properties, which facilitates heat dissipation from the sterilization lamp. The mounting component is detachably installed at the installation opening, which facilitates maintenance of the sterilization lamp.

[0039] A water purifier includes a flow-through sterilizer as described in any of the above technical solutions, the flow-through sterilizer being used to store purified water.

[0040] In this solution, by applying a flow-through sterilizer to the water purifier to store purified water, the water purifier can achieve stable pressure and continuous water output.

[0041] The positive and progressive effects of this utility model are as follows:

[0042] By incorporating a flexible air bladder within the liquid storage container, the air bladder contracts when the outlet is closed and liquid enters through the inlet, increasing the internal pressure. When the outlet is opened for dispensing, the air bladder releases pressure and expands, slowly expelling the liquid from the container. This ensures stable and continuous dispensing pressure and prevents initial splashing. Furthermore, the air bladder reduces the liquid storage space within the container, thus minimizing or preventing the growth of bacteria from excessive liquid accumulation.

[0043] By applying a flow-through sterilizer to a water purifier to store purified water, the water purifier can achieve stable pressure and continuous water output. Attached Figure Description

[0062] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0063] Example 1

[0064] This embodiment provides a flow-through sterilizer. Figures 1-6 This is a schematic diagram of the structure provided in this embodiment.

[0065] like Figures 1-3 The flow-through sterilizer 1000 includes an air bladder 2 and a liquid storage container 1. The liquid storage container 1 has an inlet 131 and an outlet 132. The air bladder 2 has an elastic air bladder body 21, which is disposed inside the liquid storage container 1 and forms a gap with the inner surface of the liquid storage container 1 to allow liquid to flow from the inlet 131 to the outlet 132.

[0066] An elastic airbag body 21 is installed inside the liquid storage container 1. When the outlet 132 is closed and liquid enters through the inlet 131, the airbag body 21 is compressed and contracts, increasing the pressure inside the airbag 2. When the outlet 132 is opened for liquid discharge, the airbag body 21 releases pressure and expands, slowly squeezing out the liquid from the storage container 1, thus stabilizing the discharge pressure, ensuring continuous discharge, and preventing liquid splashing at the beginning of discharge. Furthermore, the airbag 2 reduces the liquid storage space within the storage container 1, thereby reducing or preventing excessive liquid storage and bacterial growth. To control the opening and closing of the inlet 131 and outlet 132, on / off valves can be installed at the inlet 131 and outlet 132 for direct control, or on / off valves can be installed upstream of the inlet 131 and downstream of the outlet 132 for indirect control. It is understood that the liquid flows from upstream to downstream in the flow path.

[0067] In a preferred embodiment, such as Figure 2 , Figure 3 The airbag 2 also has an inflation part 22, on which an inflation port 221 is formed. The inflation port 221 is connected to the airbag body 21. The inflation port 221 can be repeatedly opened and closed. On the one hand, it is convenient to open the inflation port 221 to replenish the airbag 2 after the flow sterilizer 1000 has been used for a period of time, so as to maintain the liquid pressure. On the other hand, it is convenient to adjust the liquid pressure by adjusting the inflation amount of the airbag 2, so that the same airbag 2 can be used for different liquid pressures, thereby improving the versatility of the airbag 2. Figure 3 The dotted line indicates the approximate boundary between the inflation section 22 and the airbag body 21.

[0068] In a preferred embodiment, such as Figure 3The inflation part 22 extends out of the liquid storage container 1 in a sealed manner, and the inflation port 221 is located outside the liquid storage container 1. The airbag 2 can be inflated or replenished from outside the liquid storage container 1. Firstly, if the airbag 2 is inflated before being placed into the liquid storage container 1, the liquid storage container 1 needs a larger opening to allow the inflated airbag 2 to enter. In contrast, the flow-through sterilizer 1000 in this embodiment can be assembled by first placing the airbag 2 into the liquid storage container 1 and then inflating the airbag 2. This makes assembly convenient and reduces the structural size requirements of the liquid storage container 1, making the structure of the flow-through sterilizer 1000 more flexible. Secondly, replenishing the airbag 2 is convenient during the use of the flow-through sterilizer 1000. Thirdly, it can avoid contaminating the inside of the liquid storage container 1 during the inflation or replenishment process. In other embodiments, the airbag 2 can be removed from the liquid storage container 1 and then inflated, or an inflatable device can be inserted into the liquid storage container 1 through an opening to inflate the airbag 2.

[0069] In a preferred embodiment, such as Figure 3 The flow-through sterilizer 1000 also includes a sealing element 3 for sealing the air inlet 221. The air inlet 221 is closed by the sealing element 3, ensuring a reliable seal and convenient operation. Furthermore, the sealing element 3 and the air inlet 22 are detachably connected to facilitate repeated opening and closing of the air inlet 221.

[0070] In this embodiment, the sealing element 3 is made of PP (polypropylene); the airbag 2 is made of PET (polyethylene terephthalate), which has a certain antibacterial effect and also has a certain degree of elasticity, allowing it to be deformed by liquid pressure within a preset range. Both the inflatable part 22 and the sealing element 3 are made of materials with a certain degree of elasticity. The inflatable part 22 and the sealing element 3 are connected by threads to achieve a sealed and detachable connection. Furthermore, a first sealing ring 71 is provided between the inflatable part 22 and the sealing element 3 to enhance the reliability of the seal. In other embodiments, the inflatable part 22 and the sealing element 3 can be connected in a non-detachable manner by spin welding or bonding.

[0071] In other embodiments, a plug-in connection or other similar method can be used to achieve a sealed and detachable connection between the inflation part 22 and the sealing member 3.

[0072] In other embodiments, the airbag 2 can be self-sealed by the inflation part 22; for example, the material of the inflation part 22 is a flexible and easily deformable material, and the airbag 2 can be self-sealed by knotting the inflation part 22; or the self-sealing can be achieved by the mutual adsorption of the inner walls of the inflation part 22.

[0073] In a preferred embodiment, such as Figure 1 , 2The liquid storage container 1 has a channel for liquid flow that extends unidirectionally along the length of the liquid storage container 1. The inlet 131 and outlet 132 are respectively located at both ends of the length L of the liquid storage container 1. On the one hand, the liquid can flow unidirectionally along the length of the liquid storage container 1, which can prevent the formation of stagnant water zones in the liquid storage container 1 and thus prevent the liquid from deteriorating.

[0074] In a preferred embodiment, such as Figure 3 The inflation part 22 is located at the liquid outlet 132 and extends out of the liquid storage container 1 in a sealed manner from the liquid outlet 132. On the one hand, the inflation part 22 and the liquid outlet 132 share one opening on the liquid storage container 1, eliminating the need for an additional opening on the liquid storage container 1 for the inflation part 22 to extend out, thus making the structure of the liquid storage container 1 more compact. On the other hand, the inflation part 22 extends from the middle of the liquid outlet 132, which can disperse the liquid flow at the liquid outlet 132, making the liquid discharge smoother. In other embodiments, the inflation part 22 can extend out of the liquid storage container 1 from the liquid inlet 131.

[0075] In a preferred embodiment, such as Figures 2-4 The liquid storage container 1 has a connected container body 11 and two connecting parts 12. The two connecting parts 12 protrude outward from the container body 11. One connecting part 12 forms an inlet 131, and the other connecting part 12 forms an outlet 132. The inlet 131 and outlet 132 are respectively connected to the container body 11. The airbag body 21 is disposed inside the container body 11. The connecting parts 12 protrude outward from the container body 11 for three reasons: first, to facilitate the connection of the inlet 131 or outlet 132 to the inlet pipe or outlet pipe; second, to facilitate the cleaning and maintenance of the inlet 131 or outlet 132; and third, to facilitate the inflation or replenishment of the airbag 2 when the inflation part 22 extends from the middle of the inlet 131 or outlet 132. In other embodiments, the channel for liquid flow in the liquid storage container 1 can be arranged in a C-shape or S-shape and extend in a non-unidirectional manner. When the inlet 131 and the outlet 132 are located on the same side of the liquid storage container 1, the inlet 131 and the outlet 132 can be formed on the same connecting part 12 to make the structure compact. Figure 3 The dashed line in the middle indicates the approximate boundary between the container body 11 and the connecting part 12.

[0076] In a preferred embodiment, such as Figures 3-5 The connecting portion 12 forming the outlet 132 includes a connecting outer ring 121 and a connecting inner ring 122. The container body 11 is connected to the connecting outer ring 121. The connecting outer ring 121 is located on the outer periphery of the connecting inner ring 122 and is connected to the connecting inner ring 122. The outlet 132 is formed between the facing surfaces of the connecting outer ring 121 and the connecting inner ring 122. Specifically, as shown... Figure 5Four connecting ports 123 are formed between the opposing surfaces of the outer ring 121 and the inner ring 122. These four connecting ports 123 are located at the same position in the liquid storage container 1, and can be used as a liquid outlet 132.

[0077] like Figure 3 , Figure 5 An extension hole 1221 is formed in the middle of the inner ring 122, through which the inflatable part 22 of the airbag 2 extends. The inflatable part 22 and the inner ring 122 are sealed together. Sealing and fixing can be achieved by bonding or welding the inflatable part 22 and the inner ring 122, or by using a hard, non-deformable material such as rigid plastic for the inflatable part 22 to allow for an interference fit with the inner ring 122, or by threading, or by providing a sealing ring between the inflatable part 22 and the inner ring 122. It is understood that the terms flexibility, elasticity, and rigidity mentioned in this invention are relative concepts. Under the premise of fulfilling their respective functions, rigidity is relatively less prone to deformation, while elasticity or flexibility is relatively more easily deformed.

[0078] The inflation part 22 is fixed to the liquid storage container 1, which can prevent the airbag 2 from falling off and also stabilize the position of the airbag 2 relative to the liquid storage container 1, thereby stabilizing the liquid discharge. In other embodiments, the inflation part 22 can be fixed to the liquid storage container 1, or a portion of the airbag 2 can be fixed to the liquid storage container 1, so as to stabilize the position of the airbag 2 relative to the liquid storage container 1.

[0079] In a preferred embodiment, such as Figure 3 , Figure 5 The outer diameter of the sealing member 3 is larger than the inner diameter of the communicating inner ring 122, which can prevent the inflation part 22 from falling off the communicating inner ring 122 and entering the liquid storage container 1. It can be understood that the dimensions such as the inner diameter and outer diameter mentioned in this embodiment with respect to the radial direction are dimensions perpendicular to the L direction.

[0080] In a preferred embodiment, such as Figure 4The container body 11 includes a container cylinder 111 and two container transition portions 112. The two container transition portions 112 are respectively connected to the two ends of the container cylinder 111 along the length direction of the liquid storage container 1. The connecting portion 12 is connected to the container transition portion 112. The inner surface of the container body 11 is a continuous curved surface. Along the length direction of the liquid storage container 1 away from the connecting portion 12, the size of the container transition portion 112 gradually increases in the direction perpendicular to the length direction of the liquid storage container 1. The container body 11 has a cylindrical portion 111, which is convenient to process and provides balanced stress. Container transition portions 112 are provided at both ends of the cylindrical portion 111. On the one hand, this facilitates a continuous curved surface on the inner surface of the container body 11, preventing the formation of stagnant water zones within the container body 11 that hinder liquid flow and lead to liquid deterioration. On the other hand, the connecting portion 12 connects to the container transition portion 112, and the size of the container transition portion 112 gradually increases away from the connecting portion 12, facilitating liquid entry into the container body 11 from the inlet 131 or exit from the outlet 132, reducing flow resistance. Specifically, in this embodiment, the cylindrical portion 111 is cylindrical with a cylindrical inner surface, and the container transition portion 112 is spherical with a spherical inner surface. In other embodiments, the inner surface of the cylindrical portion 111 can be an elliptical cylinder, and correspondingly, the inner surface of the container transition portion 112 can be an ellipsoidal surface. Figure 4 The approximate boundaries of the container cylindrical section 111 and the container transition section 112 are indicated by dashed lines.

[0081] In a preferred embodiment, the shape of the outer surface of the airbag body 21 matches the shape of the inner surface of the container body 11, which makes the gaps between the outer surface of the airbag body 21 and the inner surface of the container body 11 more uniform, thereby further improving the function of the airbag body 21 in stabilizing the liquid outlet pressure. Furthermore, the channel for liquid flow in the liquid storage container 1 extends along the length of the liquid storage container 1, which facilitates full utilization of the function of the airbag 2 in stabilizing the liquid outlet pressure.

[0082] In a preferred embodiment, such as Figures 1-3 The flow-through sterilizer 1000 also includes a housing 4, and a liquid storage container 1 is disposed inside the housing 4, which can protect the liquid storage container 1. Specifically, such as Figure 2 , Figure 3 A second sealing ring 72 is provided between the two connecting parts 12 of the shell 4 and the liquid storage container 1 to prevent dust and other debris from entering the shell 4.

[0083] In a preferred embodiment, such as Figure 2 , Figure 3 , Figure 6The housing 4 includes a first part 41 and a second part 42. The second part 42 is fixedly connected to the connection port 411 of the first part 41 along a direction perpendicular to the length of the liquid storage container 1. The size of the connection port 411 is larger than the size of the liquid storage container 1, allowing the liquid storage container 1 to be inserted through the connection port 411 of the first part 41. The second part 42 is then connected to the first part 41, facilitating the assembly of the flow-through sterilizer 1000. Specifically, as shown... Figure 3 In this embodiment, the shell 4 is made of PP material. At the connection port 411, the first part 41 and the second part 42 have a groove on one side and a protrusion on the other, forming a matting fit. The first part 41 and the second part 42 can be welded together by spin welding. In other embodiments, the first part 41 and the second part 42 can also be connected by a detachable method such as a threaded connection.

[0084] The flow-through sterilizer 1000 also includes a sterilizer for sterilizing the liquid entering the storage container 1.

[0085] In a preferred embodiment, the liquid storage container 1 is made of a transparent material, and the sterilizer is a sterilization lamp 6, which is disposed on the outer periphery of the liquid storage container 1. The light from the sterilization lamp 6 can pass through the transparent liquid storage container 1 to sterilize the liquid inside the container 1, ensuring the quality of the liquid. Specifically, in this embodiment, the sterilization lamp 6 is installed on the outer periphery of the container cylinder 111. The sterilization lamp 6 generates heat during use, and the container cylinder 111 is cylindrical, providing good heat dissipation. Installing the sterilization lamp 6 on the cylindrical container cylinder 111 facilitates heat dissipation from the sterilization lamp 6.

[0086] In a preferred embodiment, the liquid storage container 1 is made of glass, which is convenient to manufacture, has high structural strength, good light transmittance, and good heat dissipation. In another preferred embodiment, the shell 4 is made of opaque material, such as opaque plastic or metal, to prevent the liquid inside the storage container 1 from deteriorating under normal sunlight.

[0087] In a preferred embodiment, such as Figure 1 , Figure 2 , Figure 6 The housing 4 has a mounting opening 412. The flow-through sterilizer 1000 also includes a mounting member 5, which is detachably mounted at the mounting opening 412. A sterilization lamp 6 is mounted on the side of the mounting member 5 facing the liquid storage container 1. The mounting member 5's placement on the side facing the liquid storage container 1 provides a shield to prevent the sterilization lamp 6 from shining outside the flow-through sterilizer 1000 and causing injury to personnel. The detachable mounting member 5 at the mounting opening 412 facilitates maintenance of the sterilization lamp 6. Furthermore, the mounting member 5 is made of aluminum, which has good heat dissipation properties, to facilitate heat dissipation from the sterilization lamp 6.

[0088] Specifically, such as Figure 2, Figure 4 The outer surface of the liquid storage container 1 is provided with a lamp recess 113. The sterilization lamp 6 is installed in the lamp recess 113. The mounting component 5 is fixed to the housing 4 by stainless steel screws to fix the sterilization lamp 6 in the lamp recess 113. The stainless steel screws can prevent rust. In other embodiments, the mounting component 5 can also be detachably connected to the housing 4 by a snap-fit ​​connection or other means to fix the sterilization lamp 6 to the outer periphery of the liquid storage container 1. In this embodiment, the sterilization lamp 6 is specifically a ring-shaped light strip that wraps around the lamp recess 113. There are four sterilization lamps 6, which are spaced apart along the length of the liquid storage container 1. The sterilization lamp 6 can be an LED light.

[0089] In other embodiments, the sterilizer can be located inside or outside the liquid storage container 1. When the sterilizer is located outside the liquid storage container 1, for example, a sterilization lamp 6 is used, and a heater is used to heat the liquid to achieve high-temperature sterilization. When the sterilizer is located inside the liquid storage container 1, for example, a filter with bacterial filtration function is installed in the liquid storage container 1 to isolate the liquid flow channel in the liquid storage container 1.

[0090] Example 2

[0091] This embodiment provides a water purifier that uses a flow-through sterilizer to store purified water. The flow-through sterilizer in this embodiment can be any of the flow-through sterilizers described in the above embodiments. There are numerous existing documents describing how to use a flow-through sterilizer to store purified water in a water purifier; please refer to those documents.

[0092] The water purifier can be operated in the following ways:

[0093] When purified water flows into the storage container from the inlet, the sterilization lamp is activated. The light passes through the transparent glass storage container, emitting light of different wavelengths to disinfect bacteria, thus achieving sterilization. At this time, the outlet is closed, but its opening and closing can be controlled by the solenoid valve. The sterilization lamp turns off after a 5-second delay to continue sterilization. Before the high-pressure switch detects a high-pressure signal, the water purifier continues to produce purified water and supply it into the storage container. The purified water entering the storage container compresses the air bladder, causing it to contract. When the outlet is opened to release water, the air bladder pressure is released first, and the air bladder slowly squeezes out the purified water from the storage container, stabilizing the outlet pressure and preventing spraying. When the purified water in the storage container is almost empty, the water purifier starts producing purified water again, ensuring a continuous water flow from the storage container.
