Description

Technical Field

[0001] This utility model relates to the field of purification, and in particular to an airbag filter element and a water purifier. Background Technology

[0002] In existing technologies, water purifiers cannot store purified water. In the event of a water outage or when outdoors, users will not be able to obtain purified water, which will cause great inconvenience to basic daily water needs such as drinking and cooking. Moreover, when water is needed immediately, the lack of a water storage function means that users can only wait for the water purifier to continuously filter and produce enough water, which may result in a long waiting time and affect water usage efficiency. Utility Model Content

[0003] Therefore, it is necessary to provide an airbag filter and a water purifier to address the problem that water purifiers cannot store purified water.

[0004] An airbag filter element includes: a cover assembly having a water inlet and an air inlet, the water inlet and the air inlet being arranged adjacent to each other; a water bladder assembly disposed on the cover assembly, the water bladder assembly having a water storage cavity communicating with the water inlet; and a shell assembly disposed on the cover assembly, the shell assembly and the cover assembly forming a receiving cavity, the water bladder assembly being located in the receiving cavity and capable of extending and retracting within the receiving cavity, the receiving cavity communicating with the air inlet.

[0005] The above-disclosed airbag filter element constructs a complete water inlet path by placing the water bladder assembly on the cover assembly and connecting the water storage chamber of the water bladder assembly to the water inlet of the cover assembly. This ensures a tight connection between the water bladder assembly and the cover assembly, as well as a leak-proof connection between the water storage chamber and the water inlet. If the connection is not tight or the connection structure is unreasonable, water leakage may occur. In this design, when water enters the water storage chamber, the gas in the chamber is expelled. Due to the reasonable connection structure and tight component cooperation, water leakage from the connection points is prevented, ensuring the stability of the water in the water storage chamber and allowing the water to be stored safely and completely, preventing water waste due to structural defects. A complete gas passage is constructed by placing the shell assembly on the cover assembly and connecting the cavity formed by the shell assembly and the cover assembly to the air inlet of the cover assembly. Gas can be filled into the cavity, and the air pressure in the cavity can be used to squeeze out the purified water stored in the water bladder assembly, providing purified water to the user. Furthermore, the pressure and flow rate of the gas entering the chamber can be precisely controlled to regulate the pressure exerted on the water bladder assembly. For example, when a small flow rate and precise volume of drainage are required, a lower air pressure and slower inflation speed can be used; conversely, when rapid emptying of the water bladder assembly is needed, the air pressure can be increased and the inflation speed accelerated. This precise control capability allows the air bladder filter element to meet specific water drainage requirements in various application scenarios. Simultaneously, the air pressure-based drainage method is relatively gentle, causing less structural damage to the water bladder assembly. Unlike some mechanical compression or other forceful drainage methods, the air pressure is evenly distributed on the outer surface of the water bladder assembly, avoiding the risk of localized excessive stress leading to bladder rupture or deformation. The water bladder assembly is designed to withstand a certain range of air pressure. Under this reasonable air pressure compression, the water bladder can maintain its structural integrity during multiple drainage processes, thereby extending the service life of the water bladder assembly, reducing maintenance costs and replacement frequency, and ensuring the long-term stable operation of the entire air bladder filter element.

[0006] In one embodiment, the cover assembly includes an upper shell assembly and a lower shell assembly. The upper shell assembly has a lower shell mating groove and a housing mating groove. The upper shell assembly is disposed on the lower shell assembly, and a portion of the lower shell assembly extends to the lower shell mating groove. The water bladder assembly is disposed on the lower shell assembly, and the housing assembly is disposed on the upper shell assembly, with a portion of the housing assembly extending to the housing mating groove. The lower shell assembly has the water inlet and the air inlet. By placing the upper shell assembly on the lower shell assembly and positioning the lower shell assembly at the lower shell mating groove, this structural design effectively enhances the stability of the entire device. The lower shell mating groove provides a precise positioning position for the lower shell assembly, allowing it to be stably placed within it. The tight connection between the upper and lower shell assemblies acts like a mutually supporting frame, reducing the possibility of displacement or shaking of individual components under external forces such as vibration or collision. This ensures the structural stability of the entire device during normal use and helps maintain the relative positions of the various functional components inside the device, thereby guaranteeing its normal operation. This arrangement is crucial for ensuring the device's airtightness. The lower shell mating groove serves as a fundamental part of the sealing structure. When the lower shell assembly is located within it and mates with the upper shell assembly, it forms a relatively enclosed space. This ensures that gas can completely enter the receiving cavity through the air inlet, guaranteeing stable inflation of the water bladder assembly. Placing the shell assembly on the upper shell assembly at the shell mating groove further strengthens the connection, enabling it to withstand external forces without easily loosening or separating. This ensures a tight seal between the cover assembly and the shell assembly, preventing gas leakage and maintaining stable air pressure within the receiving cavity. This allows for efficient inflation of the water bladder assembly.

[0007] In one embodiment, the upper shell assembly includes a mating component, a rotating component, and a connecting base. The rotating component is disposed on the connecting base, the mating component is disposed on the rotating component, the lower shell assembly is disposed on the rotating component and / or the connecting base, and the housing assembly is disposed on the connecting base. By placing the rotating component on the connecting base and the mating component on the rotating component, a basis for rotation of the mating component is provided. This structure allows the mating component to perform circular motion around the rotating component. Through rotational motion, the position and angle of the mating component can be easily adjusted. For example, during the installation or use of the filter element, it may be necessary to adjust the direction of the mating component according to the actual pipeline connection or the position of other equipment. The presence of the rotating component can meet this flexibility requirement, allowing the mating component to accurately dock with other components, thereby ensuring the connectivity and normal operation of the entire system. At the same time, the mating of the rotating component and the connecting base provides a placement position for the lower shell assembly, and placing the housing assembly on the connecting base provides solid support for the housing assembly. This support ensures that the housing assembly maintains a stable position under various operating conditions, ensuring that the air pressure in the receiving cavity can smoothly compress the water bladder assembly. By integrally molding and connecting the mating parts, rotating parts, and connecting base, they form a single structure. This integrity effectively reduces the risk of loosening or displacement at the connection points between the components. It eliminates the connection gaps or weak points that may occur in traditional connection methods, thereby ensuring the stability of the entire structure and providing a solid foundation for the long-term reliable operation of the airbag filter element.

[0008] In one embodiment, the mating component includes a mating thread and a mating base, the mating base being disposed on the rotating component, and the mating thread being disposed on the mating base. By placing the mating base on the rotating component and the mating thread on the mating base, the presence of the mating thread makes the installation and disassembly process more convenient. During installation, simply align the component with the mating thread with the mating thread, and then rotate to achieve connection. This simple and effective installation method does not require complex tools or operating skills, greatly improving assembly efficiency. Similarly, when it is necessary to disassemble the airbag filter element for maintenance, replacement, or cleaning, the airbag filter element can also be easily removed by rotation, which is convenient and quick, reducing maintenance time and difficulty.

[0009] In one embodiment, the mating component, the rotating component, and the connecting base are integrally formed. By integrally forming the mating component, the rotating component, and the connecting base, gas leakage from the connection points can be effectively prevented. This seamless connection reduces potential leakage channels, allowing the entire device to better maintain the stability of the internal environment during operation.

[0010] In one embodiment, the rotating component includes a rotating component body and rotating protrusions. The rotating component body is disposed on the mating component, and there are multiple rotating protrusions arranged circumferentially along the rotating component body. By placing the rotating component body on the mating component and arranging multiple rotating protrusions circumferentially along the rotating component body, the rotating component body is first disposed on the mating component, providing a basis for rotational movement. This structure allows the rotating component to rotate relative to the mating component, which is the core of achieving flexible adjustment of the entire device. When it is necessary to change the direction or angle of the mating component, the rotating component body can serve as the center of rotation, allowing the mating component to rotate in a suitable manner, thereby better adapting to different installation environments or connection requirements with other components. In the installation environment inside a water purifier, the space is relatively small, and the range of hand movement is limited, making the presence of rotating protrusions particularly important. They can serve as leverage points for operation in confined spaces, allowing users to operate the component by touching the protrusions with their fingers without having to exert much force to grip the entire rotating component. This method of leveraging space allows users to install airbag filters smoothly even in limited environments, reducing installation difficulties caused by space constraints.

[0011] In one embodiment, the lower shell assembly includes a lower shell base, a water inlet pipe, an air inlet pipe, and lower shell fixing members. The lower shell base is disposed on the upper shell assembly. Both the water inlet pipe and the air inlet pipe are disposed on the lower shell base. Multiple lower shell fixing members are arranged circumferentially along the lower shell base. The water inlet pipe has a water outlet, and the air inlet pipe has an air inlet. By placing the lower shell base on the upper shell assembly, and placing the water inlet pipe and the air inlet pipe together on the lower shell base, the upper and lower structures are integrated. This layered structural design helps to build a stable overall framework. The upper shell assembly provides a solid supporting foundation for the lower shell base, making the entire device more physically robust. The water inlet pipe and the air inlet pipe being disposed together on the lower shell base further enhances the structural integration. These pipes are tightly connected to the lower shell base, reducing loose connections between components and thus lowering the risk of pipe displacement or damage due to external vibration or other interference factors, ensuring the stability of the entire airbag filter element during operation. Multiple lower shell fixing components are arranged along the circumference of the lower shell base, which further ensures the structural stability of the entire device and makes the connection between the various components more reliable, thereby ensuring the normal operation of the airbag filter element.

[0012] In one embodiment, the water bladder assembly includes a water inlet block and a water storage bag. The water inlet block is disposed on the cover assembly, and the water storage bag is disposed on the water inlet block. The water storage bag is expandable and contractible within the receiving cavity, and the water storage bag has the water storage cavity. The water outlet communicates with the water storage cavity through the water inlet block. By placing the water inlet block on the cover assembly, the water storage bag on the water inlet block, and the water outlet communicating with the water storage cavity through the water inlet block, the water inlet block plays a crucial connecting role. The water outlet is the starting point for external water to enter the device. Through the connection between the water inlet block and the water storage cavity, a complete and orderly water introduction path is constructed. When water enters the water storage cavity, the water storage bag expands outward under water pressure. When water is needed, gas enters the receiving cavity and squeezes the water storage bag, expelling the water inside the water storage bag through the water outlet to the outside, providing the user with pure drinking water. The placement of the water inlet block between the cover assembly and the water storage bag helps ensure the airtightness of the connection. Because sealing performance is crucial during water storage, even the smallest gap can lead to leakage. A tight connection between the inlet block, the cover assembly, and the water storage bag effectively prevents water from seeping out from the connection points, avoiding water leakage into the storage cavity and wasting water resources.

[0013] In one embodiment, the housing assembly includes a mating upper shell and a housing body. The mating upper shell is clamped within the housing mating groove of the cover assembly, and the housing body is disposed on the mating upper shell. The water bladder assembly can contact or separate from the housing body. The mating upper shell and the housing body are integrally formed. By clamping the mating upper shell within the housing mating groove of the cover assembly, and then placing the housing body on the mating upper shell, the mating upper shell, clamped within the housing mating groove of the cover assembly, provides a stable connection foundation for the entire structure. The housing mating groove can precisely position the mating upper shell, preventing positional displacement during installation. Furthermore, the clamping structure between the mating upper shell and the housing mating groove helps improve the device's sealing performance. When the housing body is disposed on the mating upper shell, a relatively enclosed receiving space is formed. Good sealing performance is crucial for maintaining stable internal air pressure within the device. When the water bladder assembly is full of water, it comes into close contact with the housing body, preventing it from expanding indefinitely. This mechanism effectively prevents damage from excessive expansion, protecting the physical integrity of the water bladder assembly and extending its service life. By integrally molding the upper shell and the housing body, gaps and connecting parts between them are eliminated, making the entire structure a seamless whole. During the operation of the air bladder filter element, especially when subjected to external vibrations, impacts, or internal pressure changes, the integrally molded structure can more effectively resist these external forces. The elimination of the risk of loosening or separation at connection points greatly enhances the structural strength between parts, providing a more stable and protective space for the internal water bladder assembly. Simultaneously, the integral molding method avoids potential sealing problems between the upper shell and the housing body. In traditional connection methods, the connection surface between the two components may lead to gas leakage due to poor sealing. However, the integral molding reduces potential leakage channels, preventing internal gas leakage.

[0014] In one embodiment, the housing body includes a shell and supporting members. The shell is disposed on the mating upper shell, and there are multiple supporting members arranged circumferentially around the bottom of the shell. By placing the shell on the mating upper shell and circumferentially arranging multiple supporting members around the bottom of the shell, the mating upper shell provides a stable support foundation for the shell, allowing the shell to be firmly held in a certain position. The multiple supporting members arranged circumferentially around the bottom of the shell further enhance its stability. These supporting members can distribute the pressure borne by the shell, whether it is pressure from the internal water bladder assembly or potential external impacts, effectively distributing it to each supporting member. Furthermore, the circumferentially distributed supporting members can evenly distribute these pressures within a circumferential range, avoiding excessive local pressure and thus preventing the shell from tilting or deforming.

[0015] The second aspect of this application discloses a water purifier, which includes: the aforementioned airbag filter element; and a water purification system, wherein the airbag filter element is disposed on the water purification system.

[0016] The second aspect disclosed above discloses a water purifier that effectively enhances the water storage capacity of the entire water purification system by incorporating an airbag filter element. During the water purification process, the water production rate and water demand may not always match. The airbag filter element, as a component that stores purified water, can store excess purified water during peak production periods and release the stored water when water demand is high, acting as a buffer and balancing mechanism to avoid water waste or insufficient supply due to time or flow differences between water production and consumption. Especially when the water purifier is taken outdoors, water sources may be contaminated or difficult to access. The water stored in the airbag filter element, after purification, can meet basic drinking needs. This is a crucial lifeline for hikers, wilderness explorers, or people encountering emergencies such as natural disasters that damage their water supply systems, ensuring they still have clean drinking water when they cannot use the water purifier to produce water or find other water sources.

[0030] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0032] The following describes some embodiments of the airbag filter element and water purifier of this utility model with reference to the accompanying drawings.

[0033] Example 1

[0034] like Figures 1 to 9As shown, this embodiment discloses an airbag filter element, including: a cover assembly 1, which has a water inlet 101 and an air inlet 102, which are arranged adjacent to each other; a water bladder assembly 2, which is disposed on the cover assembly 1 and has a water storage cavity 201, which is connected to the water inlet 101; and a shell assembly 3, which is disposed on the cover assembly 1 and the shell assembly 3 and the cover assembly 1 enclose a receiving cavity 301, in which the water bladder assembly 2 is located and can extend and retract within the receiving cavity 301, and the receiving cavity 301 is connected to the air inlet 102.

[0035] This application discloses an airbag filter element. By placing the water bladder assembly 2 on the cover assembly 1 and connecting the water storage cavity 201 of the water bladder assembly 2 to the water inlet 101 of the cover assembly 1, a complete water inlet path is constructed, thus ensuring the tight connection between the water bladder assembly 2 and the cover assembly 1, as well as the sealing of the connection between the water storage cavity 201 and the water inlet 101. If the connection between the two is not tight or the connection structure is unreasonable, water may leak. In this design, when water enters the water storage cavity 201, it will expel the gas in the receiving cavity 301. Due to the reasonable connection structure and tight component cooperation, water can be prevented from seeping out from the connection point, ensuring the stability of water in the water storage cavity 201, so that water can be stored completely and safely, and water resources will not be wasted due to structural defects. By placing the shell assembly 3 on the cover assembly 1 and connecting the receiving cavity 301 formed by the shell assembly 3 and the cover assembly 1 to the air inlet 102 of the cover assembly 1, a complete gas passage is constructed. Gas can be injected into the receiving chamber 301, and the air pressure in the receiving chamber 301 can be used to squeeze out the purified water stored in the water bladder assembly 2, providing purified water to the user. Furthermore, the squeezing force on the water bladder assembly 2 can be precisely controlled by adjusting the gas pressure and flow rate. For example, when a small flow rate and precise volume of drainage are required, a lower air pressure and a slower inflation speed can be used; conversely, when rapid drainage of the water bladder assembly 2 is needed, the air pressure can be increased and the inflation speed accelerated. This precise control capability allows the air bladder filter element to meet specific water drainage requirements in different application scenarios. At the same time, the air pressure squeezing drainage method is relatively gentle, causing less structural damage to the water bladder assembly 2. Unlike some mechanical squeezing or other forceful drainage methods, the air pressure is evenly distributed on the outer surface of the water bladder assembly 2, avoiding the risk of localized excessive stress leading to bladder rupture or deformation. The water bladder assembly 2 is designed to withstand a certain range of air pressure. Under this reasonable air pressure, the water bladder can maintain its structural integrity during multiple drainage processes, thereby extending the service life of the water bladder assembly, reducing maintenance costs and replacement frequency, and ensuring the long-term stable operation of the entire air bladder filter element.

[0036] like Figure 1 , Figure 5 and Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further defines: the cover assembly 1 includes an upper shell assembly 11 and a lower shell assembly 12. The upper shell assembly 11 is provided with a lower shell mating groove 103 and a shell mating groove 104. The upper shell assembly 11 is disposed on the lower shell assembly 12, and a portion of the lower shell assembly 12 extends to the lower shell mating groove 103. The water bladder assembly 2 is disposed on the lower shell assembly 12. The shell assembly 3 is disposed on the upper shell assembly 11, and a portion of the shell assembly 3 extends to the shell mating groove 104. The lower shell assembly 12 is provided with a water inlet 101 and an air inlet 102. By disposing of the upper shell assembly 11 on the lower shell assembly 12 and positioning the lower shell assembly 12 at the lower shell mating groove 103, this structural design effectively enhances the stability of the entire device. The lower shell mating groove 103 provides a precise positioning position for the lower shell assembly 12, allowing the lower shell assembly 12 to be stably placed therein. The tight fit between the upper shell assembly 11 and the lower shell assembly 12 acts like a mutually supporting frame, reducing the possibility of displacement or shaking of individual components under external forces such as vibration or collision. This ensures the structural stability of the entire device during normal use and helps maintain the relative positions of the various functional components inside, thus guaranteeing the normal operation of the device. This design is crucial for ensuring the device's airtightness. The lower shell mating groove serves as the foundation of a sealing structure. When the lower shell assembly is located within it and mates with the upper shell assembly, it forms a relatively enclosed space, ensuring that gas can completely enter the receiving cavity 301 through the air inlet 102, guaranteeing stable inflation of the water bladder assembly 2. Placing the shell assembly 3 on the upper shell assembly 11 and at the shell mating groove 104 makes the connection between them more stable, able to withstand certain external forces without easily loosening or separating. This ensures the airtightness between the cover assembly 1 and the shell assembly 3, preventing the injected gas from leaking out and ensuring stable air pressure in the receiving cavity 301, enabling efficient inflation of the water bladder assembly 3.

[0037] like Figure 5 and Figure 7As shown, in addition to the features of the above embodiments, this embodiment further defines: the upper shell assembly 11 includes a mating member 111, a rotating member 112, and a connecting base 113. The rotating member 112 is disposed on the connecting base 113, the mating member 111 is disposed on the rotating member 112, the lower shell assembly 12 is disposed on the rotating member 112 and / or the connecting base 113, and the shell assembly 3 is disposed on the connecting base 113. By disposing the rotating member 112 on the connecting base 113 and the mating member 111 on the rotating member 112, a basis for rotation of the mating member 111 is provided. This structure allows the mating member 111 to perform circular motion around the rotating member 112. Through rotational motion, the position and angle of the mating member 111 can be easily adjusted. For example, during the installation or use of the filter element, it may be necessary to adjust the direction of the mating member 111 according to the actual pipeline connection or the position of other equipment. The presence of the rotating member 112 can meet this flexibility requirement, enabling the mating member 111 to accurately dock with other components, thereby ensuring the connectivity and normal operation of the entire system. Meanwhile, the cooperation between the rotating component 112 and the connecting base 113 provides a placement position for the lower shell assembly 12. Placing the shell assembly 3 on the connecting base 113 provides solid support for the shell assembly. This support ensures that the shell assembly maintains a stable position under various operating conditions, guaranteeing that the air pressure in the receiving cavity 301 can smoothly compress the water bladder assembly 2. The mating component 111, the rotating component 112, and the connecting base 113 are integrally formed and connected, making them a single structure. This integrity effectively reduces the risk of loosening or displacement at the connection points between components, eliminating the gaps or weak points that may occur in traditional connection methods. This ensures the stability of the entire structure and provides a solid foundation for the long-term reliable operation of the air bladder filter element.

[0038] like Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the mating component 111 includes a mating thread 1111 and a mating base 1112, the mating base 1112 is disposed on the rotating component 112, and the mating thread 1111 is disposed on the mating base 1112. By disposing the mating base 1112 on the rotating component 112 and the mating thread 1111 on the mating base 1112, the presence of the mating thread 1111 makes the installation and disassembly process more convenient. During installation, it is only necessary to align the component with the matching thread with the mating thread 1111 and then rotate it to achieve connection. This simple and effective installation method does not require complicated tools or operating skills, greatly improving assembly efficiency. Similarly, when it is necessary to disassemble the airbag filter element for maintenance, replacement, or cleaning, the airbag filter element can also be easily removed by rotation, which is convenient and quick, reducing maintenance time and difficulty.

[0039] like Figure 5As shown, in addition to the features of the above embodiments, this embodiment further defines that the mating part 111, the rotating part 112, and the connecting base 113 are integrally formed. By integrally forming the mating part 111, the rotating part 112, and the connecting base 113, gas leakage from the connection point can be effectively prevented. This seamless connection reduces potential leakage channels, enabling the entire device to better maintain the stability of the internal environment during operation.

[0040] like Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further defines: the rotating member 112 includes a rotating member body 1121 and rotating protrusions 1122. The rotating member body 1121 is disposed on the mating member 111, and the number of rotating protrusions 1122 is multiple, with the multiple rotating protrusions 1122 arranged circumferentially along the rotating member body 1121. By disposing the rotating member body 1121 on the mating member 111 and arranging the multiple rotating protrusions 1122 circumferentially along the rotating member body 1121, the rotating member body 1121 is first disposed on the mating member 111, providing a basis for rotational movement. This structure allows the rotating member 112 to rotate relative to the mating member 111, which is the core of achieving flexible adjustment of the entire device. When it is necessary to change the direction or angle of the mating member, the rotating member body 1121 can serve as the center of rotation, allowing the mating member to rotate in a suitable manner, thereby better adapting to different installation environments or connection requirements with other components. In the confined space inside a water purifier, where hand movement is limited, the rotating protrusions 1122 become particularly important. These protrusions serve as leverage points for operation within this confined space, allowing users to operate the device simply by touching the protrusions with their fingers, rather than gripping the entire rotating component 112 with great force. This leverage mechanism within a limited space enables users to smoothly install the airbag filter cartridge even in restrictive environments, reducing installation difficulties caused by space constraints.

[0041] like Figure 3 , Figure 4 and Figure 5As shown, in addition to the features of the above embodiments, this embodiment further defines: the lower shell assembly 12 includes a lower shell base 121, a water pipe 122, an air inlet pipe 123, and lower shell fixing members 124. The lower shell base 121 is disposed on the upper shell assembly 11. The water pipe 122 and the air inlet pipe 123 are both disposed on the lower shell base 121. There are multiple lower shell fixing members 124, which are arranged circumferentially along the lower shell base 121. The water pipe 122 is provided with a water outlet 101, and the air inlet pipe 123 is provided with an air inlet 102. By disposing of the lower shell base 121 on the upper shell assembly 11, and disposing of the water pipe 122 and the air inlet pipe 123 together on the lower shell base 121, the integration of the upper and lower structures is achieved. This layered structural design helps to build a stable overall framework. The upper shell assembly 11 provides a solid supporting foundation for the lower shell base 121, making the entire device more physically robust. The water inlet pipe 122 and the air inlet pipe 123 are both mounted on the lower housing base 121, further enhancing the structural integration. These pipes are tightly connected to the lower housing base, reducing loose connections between components and thus lowering the risk of pipe displacement or damage due to external vibration or other interference factors, ensuring the stability of the entire airbag filter element during operation. Multiple lower housing fixing members 124 are arranged circumferentially along the lower housing base 121, further ensuring the structural stability of the entire device and making the connections between components more reliable, thereby ensuring the normal operation of the airbag filter element.

[0042] like Figure 1 and Figure 8As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the water bag assembly 2 includes a water inlet block 21 and a water storage bag 22. The water inlet block 21 is disposed on the cover assembly 1, and the water storage bag 22 is disposed on the water inlet block 21. The water storage bag 22 can extend and retract within the receiving cavity 301. The water storage bag 22 has a water storage cavity 201, and the water outlet 101 is connected to the water storage cavity 201 through the water inlet block 21. By disposing of the water inlet block 21 on the cover assembly 1, disposing of the water storage bag 22 on the water inlet block 21, and connecting the water outlet 101 to the water storage cavity 201 through the water inlet block 21, the water inlet block 21 plays a crucial role in connecting the upper and lower parts. The water outlet 101 is the starting point for external water to enter the device. Through the connection between the water inlet block 21 and the water storage cavity 201, a complete and orderly water introduction path is constructed. When water enters the water storage chamber 201, the water storage bag 22 expands outward under water pressure. When water is needed, gas enters the receiving chamber 301, squeezing the water storage bag 22 and expelling the water inside through the water outlet 101 to the outside, providing users with clean drinking water. The placement of the water inlet block 21 between the cover assembly 1 and the water storage bag 22 helps ensure the tightness of the connection. Because sealing performance is crucial during water storage, any tiny gap can lead to water leakage. The tight connection between the water inlet block 21 and the cover assembly 1 and the water storage bag 22 effectively prevents water from seeping out from the connection point, avoiding water leakage into the receiving chamber 301 and wasting water resources.

[0043] like Figure 1 , Figure 2 and Figure 9As shown, in addition to the features of the above embodiments, this embodiment further defines: the housing assembly 3 includes a mating upper shell 31 and a housing body 32. The mating upper shell 31 is clamped in the housing mating groove 104 of the cover assembly 1, and the housing body 32 is disposed on the mating upper shell 31. The water bladder assembly 2 can contact or separate from the housing body 32. The mating upper shell 31 and the housing body 32 are integrally formed. By clamping the mating upper shell 31 in the housing mating groove 104 of the cover assembly 1, and then disposing of the housing body 32 on the mating upper shell 31, on the one hand, the mating upper shell 31 clamped in the housing mating groove 104 of the cover assembly 1 provides a stable connection foundation for the entire structure. The housing mating groove 104 can accurately position the mating upper shell 31, preventing positional displacement during installation. On the other hand, the clamping structure of the mating upper shell 31 and the housing mating groove 104 helps to improve the sealing performance of the device. When the housing body 32 is mounted on the mating shell 31, a relatively enclosed space is formed. Good sealing is crucial for maintaining stable internal air pressure. When the water bladder assembly 2 is full of water, it comes into close contact with the housing body 32, preventing it from expanding indefinitely. This mechanism effectively prevents damage from excessive expansion, protecting the physical integrity of the water bladder assembly 2 and extending its service life. By integrally molding the mating shell 31 and the housing body 32, gaps and connecting parts between them are eliminated, making the entire structure a seamless whole. During the operation of the air bladder filter, especially when subjected to external vibrations, impacts, or internal pressure changes, the integrally molded structure can more effectively resist these external forces. Without the risk of loosening or separation at the connection points, the structural strength between the parts is greatly improved, providing a more stable and protective space for the internal water bladder assembly 2. Simultaneously, the integral molding method avoids potential sealing problems between the mating shell 31 and the housing body 32. In traditional connection methods, the connection surface between the two components may lead to gas leakage due to poor sealing. By using a one-piece molding process, potential leakage channels are reduced, thus preventing internal gas leakage.

[0044] like Figure 9As shown, in addition to the features of the above embodiments, this embodiment further defines: the shell body 32 includes a shell body 321 and support members 322. The shell body 321 is disposed on the mating shell 31, and there are multiple support members 322 arranged circumferentially around the bottom of the shell body 321. By disposing of the shell body 321 on the mating shell 31 and circumferentially arranging multiple support members 322 around the bottom of the shell body 321, the mating shell 31 provides a stable support foundation for the shell body 321, enabling the shell body 321 to be stably held in a certain position. The circumferential arrangement of multiple support members 322 around the bottom of the shell body 321 further enhances the stability of the shell body 321. These support members 322 can disperse the pressure borne by the shell body, whether it is the pressure from the internal water bladder assembly or possible external impact forces, which can be effectively dispersed to each support member. Moreover, the circumferentially distributed support members 322 can evenly distribute these pressures within a circumferential range, avoiding excessive local pressure, thereby preventing the shell body 321 from tilting or deforming.

[0045] Example 2

[0046] like Figures 1 to 9 As shown, this embodiment discloses a water purifier, including: the above-mentioned airbag filter element; and a water purification system, wherein the airbag filter element is disposed on the water purification system.

[0047] The second aspect of this application discloses a water purifier that effectively enhances the water storage capacity of the entire water purification system by incorporating an airbag filter element. During the water purification process, the water production rate and water demand may not always match. The airbag filter element, as a component for storing purified water, can store excess purified water during peak production periods and release the stored water when water demand is high, acting as a buffer and balancing mechanism to avoid water waste or insufficient supply due to time or flow differences between water production and consumption. Especially when the water purifier is taken outdoors, water sources may be contaminated or difficult to access. The water stored in the airbag filter element, after purification, can meet basic drinking needs. This is a crucial lifeline for hikers, wilderness explorers, or people encountering emergencies such as natural disasters that damage their water supply systems, ensuring they still have clean drinking water when they cannot use the water purifier to produce water or find other water sources.

[0048] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
