Description

Technical Field

[0001] This utility model relates to the technical field of water filtration and purification devices, and in particular to a manual booster filter. Background Technology

[0002] Outdoor filtration equipment is commonly used in rescue operations and outdoor work. When collecting water in the wild or outdoors, it is usually necessary to use outdoor filtration equipment to filter and purify the water source. Existing outdoor filtration equipment includes electric filters and press-type filters. Electric filters have the disadvantages of requiring electricity and having a small flow rate. Press-type filters do not require a power source outdoors, thus overcoming the disadvantage of needing electricity. However, both types of outdoor filtration equipment have the problem of insufficient venting or accidental air intake during operation, which leads to a reduction in water production and affects water production efficiency. Utility Model Content

[0003] This utility model provides a manual booster filter to solve the technical problem that existing outdoor filtration equipment suffers from insufficient venting or accidental air intake during operation, which affects water production efficiency.

[0004] This utility model provides a manual booster filter, the manual booster filter comprising:

[0005] A detachable cover and a cylindrical body, wherein the cover is provided with a water inlet connector and a water outlet connector, and the cover body is provided with a water inlet channel communicating with the water inlet connector and a water outlet channel communicating with the water outlet connector.

[0006] The filter element assembly, built into the cylinder, is used to filter the incoming water;

[0007] A pressurizing component, disposed on the cover, is used to provide inlet pressure to introduce unfiltered water from the inlet connector into the inlet channel and into the cylinder for filtration.

[0008] A pressure relief assembly is available to switch between a first state and a second state. In the first state, the interior of the cylinder is connected to the outside, while in the second state, the interior of the cylinder is not connected to the outside.

[0009] In one embodiment of the present invention, the pressure relief assembly includes a vent hole and a vent valve that can be manually controlled to open and close the vent hole. The vent hole is located at the bottom of the cylinder and is used to connect the interior of the cylinder with the outside.

[0010] In one embodiment of the present invention, the vent valve is sealed on the vent hole, and the vent valve is detachably connected to the vent hole by means of threads.

[0011] In one embodiment of this utility model, the pressurizing component includes a pressure chamber disposed within the cover body, a piston disposed within the pressure chamber, a first transmission rod, a second transmission rod, and a rocker arm. The pressure chamber is connected to the water inlet channel. The first transmission rod is connected to the piston. The rocker arm is connected to both the first transmission rod and the second transmission rod. By rocking the rocker arm, the first transmission rod and the second transmission rod are moved. The first transmission rod drives the piston to move within the pressure chamber to provide water inlet pressure to the water inlet channel.

[0012] In one embodiment of the present invention, the rocker arm is configured with an arc-shaped structure, and the rear end of the rocker arm has a hand-held portion for gripping and rocking the rocker arm.

[0013] In one embodiment of the present invention, the filter element assembly includes a first filter element and a second filter element that are detachably connected. Unfiltered water flows from the water inlet channel through the second filter element and the first filter element in sequence for filtration before flowing into the water outlet channel.

[0014] In one embodiment of the present invention, the first filter element is an ultrafiltration membrane filter element, and the second filter element is an activated carbon filter element or a composite filter element formed by an activated carbon filter element and a filter layer.

[0015] In one embodiment of the present invention, the cylinder and the cover are detachably connected by threads, and a sealing ring is provided at the connection of the cylinder to seal the connection between the cylinder and the cover.

[0016] In one embodiment of the present invention, the manual booster filter further includes a pre-filter head for filtering large particles. The pre-filter head is connected to the water inlet connector via a water inlet pipe. The interior of the pre-filter head is connected to the water inlet pipe, and a filter screen is provided at the connection between the filter head and the water inlet pipe.

[0017] In one embodiment of the present invention, the pre-filter head further includes a counterweight block, which is filled with a substance with a density greater than that of water.

[0018] The beneficial effects of this utility model are as follows: The manual pressure booster filter proposed in this utility model first switches the pressure relief component to the first state, connecting the inside of the cylinder to the outside. The pressure booster component provides inlet water pressure, introducing unfiltered water from the inlet connector into the inlet channel and into the cylinder until a stable water flow comes out from the pressure relief component. The outflow of water discharges the air inside the cylinder, ensuring sufficient venting and avoiding insufficient venting from affecting the water production efficiency. Then, the pressure relief component is switched to the second state, disconnecting the inside of the cylinder from the outside. At this time, the water inside the cylinder will be filtered by the filter element component. The filtered clean water flows into the outlet channel and out from the outlet connector. During the operation of the filter, if an accidental air intake causes the water production to decrease, simply switch the pressure relief component back to the first state and repeat the venting operation to expel the accidentally entered air, avoiding accidental air intake during operation from affecting the water production efficiency.

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0028] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. The drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0029] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the present invention. However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the present invention.

[0030] Please see Figures 1 to 4 This utility model provides an example of a manual booster filter, comprising:

[0031] The cover 1 and the cylinder 2 are detachably connected. The cover 1 is provided with a water inlet connector 3 and a water outlet connector 4. The cover 1 is provided with a water inlet channel 14 communicating with the water inlet connector 3 and a water outlet channel 19 communicating with the water outlet connector 4.

[0032] The filter element assembly, built into the cylinder 2, is used to filter the incoming water;

[0033] A pressurizing component, mounted on the cover 1, is used to provide inlet water pressure to introduce unfiltered water from the inlet connector 3 into the inlet channel 14 and into the cylinder 2 for filtration.

[0034] The pressure relief component can switch between a first state and a second state. In the first state, the inside of the cylinder 2 is connected to the outside, and in the second state, the inside of the cylinder 2 is not connected to the outside.

[0035] It should be noted that existing electric filters are usually RO filters. RO filters have a small flow rate and require power. In field or outdoor conditions, they have the disadvantages of needing electricity and having a small flow rate, resulting in low water production efficiency and a poor user experience. Press-type filters usually use a direct press-type piston pressurization + high-precision UF solution, but they have the disadvantage of requiring a large pressing force, resulting in a poor user experience. In addition, when these two types of outdoor filtration devices have incomplete venting or accidental air intake during operation, and the filter element is in a wet state, air has difficulty penetrating the membrane layer, affecting water production efficiency. Press-type filters may also experience stiff back-and-forth movement of the pressing handle during operation, causing a significant reduction in water production.

[0036] In the manual booster filter provided in this embodiment, the pressure relief component is first switched to the first state, so that the inside of the cylinder 2 is connected to the outside. The booster component provides inlet water pressure, and unfiltered water is introduced into the inlet channel 14 from the inlet connector 3 and flows into the cylinder 2 until a stable water flow comes out from the pressure relief component. The air in the cylinder 2 is discharged through the water flow to ensure sufficient venting and avoid insufficient venting from affecting the water production efficiency. Then the pressure relief component is switched to the second state, and the inside of the cylinder 2 is not connected to the outside. At this time, the water in the cylinder 2 will be filtered by the filter element component. The filtered clean water flows into the outlet channel and flows out from the outlet connector 4. During the operation of the filter, if an accidental air intake causes the water production to decrease, the pressure relief component is switched back to the first state, and the venting operation is repeated to discharge the accidentally entered air, so as to avoid the accidental air intake during operation from affecting the water production efficiency.

[0037] In this embodiment, the pressure relief assembly includes a vent hole 17 and a vent valve 16 that can be manually controlled to open and close the vent hole 17. Specifically, the vent hole 17 can be located at the bottom of the cylinder 2 to connect the inside of the cylinder 2 with the outside. When the vent valve 16 is manually controlled to open the vent hole 17, the pressure relief assembly switches to the first state, and the inside of the cylinder 2 is connected to the outside. When the vent valve 16 is manually controlled to close the vent hole 17, the pressure relief assembly switches to the second state, and the inside of the cylinder 2 is not connected to the outside.

[0038] In detail, the vent valve 16 is sealed on the vent hole 17. The vent valve 16 is detachably connected to the vent hole 17 by a thread. The opening and closing of the vent hole 17 can be controlled by rotating the vent valve 16.

[0039] The specific implementation of the pressure relief component is not limited to the above-described implementation methods. As long as the switching between the two states mentioned above can be achieved, the purpose of this application can be realized. For example, the vent valve can open or close the vent hole 17 through other non-threaded means.

[0040] In this embodiment, the pressurization assembly includes a pressure chamber 18 disposed within the cover 1, a piston 15 disposed within the pressure chamber 18, a first transmission rod 13, a second transmission rod 7, and a rocker arm 5. The pressure chamber 18 is connected to the water inlet channel 14. The first transmission rod 13 is connected to the piston 15, and the rocker arm 5 is connected to both the first transmission rod 13 and the second transmission rod 7. By shaking the rocker arm 5, the first transmission rod 13 and the second transmission rod 7 are moved. The first transmission rod 13 drives the piston 15 to move within the pressure chamber 18 to provide water pressure to the water inlet channel 14. Specifically, by manually driving the rocker arm 5 to rotate, the first transmission rod 13 is driven to move the piston 15 within the pressure chamber 18. When the rocker arm 5 rotates away from the cylinder 2, the first transmission rod 13 drives the piston 15 to slide away from the water inlet channel 14 in the pressure chamber 18. At this time, the pressure chamber 18 is in a negative pressure state, drawing the water to be filtered into the front end of the water inlet channel 14 and into the pressure chamber 18. When the rocker arm 5 rotates towards the cylinder 2, the first transmission rod 13 drives the piston 15 to slide towards the water inlet channel 14 in the pressure chamber 18. At this time, the pressure chamber 18 is in a pressurized state, generating inlet pressure. The water to be filtered flows out of the pressure chamber 18 and into the rear end of the water inlet channel 14 and into the cylinder 2. The rotation of the rocker arm 5 is repeated to achieve water intake for the filter.

[0041] In the above embodiment, one end of the second transmission rod 7 is connected to the cover 1, and the other end of the second transmission rod 7 is connected to the rocker arm 5. Specifically, the connection between the second transmission rod 7 and the rocker arm 5 is the rotation fulcrum of the rocker arm 5. When the filter is not used, the second transmission rod 7 is in an inclined position. During the rotation of the rocker arm 5, the second transmission rod 7 changes from an inclined position to a horizontal position to adjust the position of the rotation fulcrum of the rocker arm 5, so that the rocker arm 5 always drives the first transmission rod 13 to move horizontally, thereby ensuring that the piston 15 slides smoothly in the pressure chamber 18.

[0042] In some embodiments, the rocker arm 5 is configured with an arc-shaped structure, and the rear end of the rocker arm 5 has a hand-held part 6 for gripping and rocking the rocker arm 5. Specifically, the rocker arm 5 with an arc-shaped structure design can not only reduce the overall size of the filter product and facilitate user operation, but also ensure that there is always a certain distance between the hand-held part 6 and the cylinder 2. When the user is rocking the rocker arm 5, they need to hold the cylinder 2 and the rocker arm 5 respectively to prevent their hand from being squeezed by the rocker arm 5 and the cylinder 2 during operation, thus improving the user experience.

[0043] In this embodiment, the filter element assembly includes a detachably connected first filter element 9 and a second filter element 10. Unfiltered water flows from the inlet channel 14 through the second filter element 10 and the first filter element 9 in sequence for filtration before flowing into the outlet channel 19. Specifically, both the first filter element 9 and the second filter element 10 are cylindrical structures. The first filter element 9 has an outlet 11 at one end near the cover 1 that communicates with the outlet channel 19. The side wall of the second filter element 10 is circumferentially provided with an inlet 12 that communicates with the inlet channel 14. The water to be filtered flows into the inlet channel 14 and enters the second filter element 10 through the circumferential inlet 12 on the side wall of the second filter element 10 for filtration before entering the first filter element 9 for filtration. The filtered clean water flows into the outlet channel 19 through the outlet 11.

[0044] Furthermore, the first filter element 9 is an ultrafiltration membrane filter element, and the second filter element 10 is an activated carbon filter element or a composite filter element formed by an activated carbon filter element and a filter layer. Specifically, both the first filter element 9 and the second filter element 10 are detachable, making it easy to replace the filter elements. The activated carbon filter element and the ultrafiltration membrane filter element can remove harmful substances such as heavy metals, bacteria, viruses, PFAS (per- and polyfluoroalkyl substances), and BPA (bisphenol A), effectively protecting the safety of outdoor drinking water.

[0045] In one embodiment, when the second filter element 10 is a composite filter element formed by an activated carbon filter element and a filter layer, the filter layer can be a large particle filter layer such as PP cotton or non-woven fabric. The filter layer surrounds the side wall circumferentially of the second filter element 10. The incoming water first passes through the filter layer for large particle filtration and enters the second filter element 10 through the inlet 12, and then passes through the activated carbon filter element in the second filter element 10 for filtration.

[0046] Filter cartridge assemblies are not limited to the above implementation methods and can be single-stage, two-stage, three-stage, or more stages. The specific filtration type settings of filter cartridge assemblies are also not limited to the above implementation methods; for example, they can also be KDF filter cartridges, GAC filter cartridges, wound filter cartridges, and melt-blown filter cartridges. KDF filter cartridges are high-purity copper alloys that can perfectly remove heavy metals and acid ions from water, improving the activation level of the water. GAC filter cartridges are granular activated carbon filter cartridges.

[0047] In this embodiment, the cylinder 2 and the cover 1 are detachably connected by threads. A sealing ring 8 is fitted at the connection of the cylinder 2 to seal between the cylinder 2 and the cover 1. The sealing connection between the two is achieved by the threaded connection between the cylinder 2 and the cover 1 and the sealing ring 8.

[0048] In this embodiment, the manual booster filter also includes a pre-filter head 20 for filtering large particles. The pre-filter head 20 is connected to the inlet connector 3 via an inlet pipe 21. The interior of the pre-filter head 20 is connected to the inlet pipe 21, and a filter screen is provided at the connection between the filter head and the inlet pipe 21. Specifically, both the pre-filter head 20 and the inlet pipe 21 are detachable structures. When not in use, they can be removed for easy storage. When in use, the pre-filter head 20 is placed in an outdoor water source. The filter screen can screen out large particles, preventing large particles from entering the filter or clogging the inlet pipe 21, thus effectively protecting the filter life.

[0049] In the above embodiment, the pre-filter head 20 also includes a counterweight block filled with a substance with a density greater than that of water. The counterweight block ensures that the pre-filter head 20 can automatically sink into the water when placed in an outdoor water source.

[0050] It is worth noting that before using the filter, the inlet connector 3 is connected to one end of the inlet pipe 21, the other end of the inlet pipe 21 is connected to the pre-filter head 20, and the outlet connector 4 is connected to the outlet pipe 22. After completing the preparation, the pre-filter head 20 and at least part of the inlet pipe 21 are completely immersed in water to ensure that air-free water enters the filter and prevents a large amount of air from entering during the water intake process. Rotate the air release valve 16 to open the air release hole 17, so that the inside of the filter element assembly is connected to the outside air. Shake the rocker arm 5 to pressurize the water intake until a stable flow of water flows out of the air release hole 17, and the internal air is discharged through the water flow. Rotate the air release valve 16 in the opposite direction to close the air release hole 17, so that the inside of the filter element assembly is isolated from the outside air and prevents air from entering. Continue to shake the rocker arm 5 to continue water intake and filtration. The filtered clean water flows from the outlet 11 into the outlet channel 19 and enters the outlet pipe 22 through the outlet connector 4 to send out the filtered clean water.

[0051] In summary, in the manual booster filter provided in this embodiment, the vent valve 16 is first manually controlled to open the vent hole 17, switching the pressure relief assembly to the first state, so that the filter element assembly inside the cylinder 2 is connected to the outside. The booster assembly provides inlet water pressure, introducing unfiltered water from the inlet connector 3 into the inlet channel 14 and into the cylinder 2 until a stable water flow comes out from the vent hole 17. At this time, the water entering the cylinder 2 will flow out directly from the vent hole 17, and the air inside the cylinder 2 will be discharged through the water flow, ensuring sufficient venting and avoiding insufficient venting from affecting the water production efficiency. Then, the vent valve 16 is manually controlled to open the vent hole 17. When the air valve 16 closes the vent hole 17, the pressure relief component is switched to the first state. At this time, the water in the cylinder 2 will be filtered by the filter element assembly. The filtered clean water flows into the water outlet and flows out from the water outlet connector 4. During the operation of the filter, if an accidental air intake causes the water production to decrease, simply manually control the air valve 16 to open the vent hole 17, switch the pressure relief component to the first state, repeat the air venting operation to expel the accidentally entered air, and then manually control the air valve 16 to close the vent hole 17 and switch the pressure relief component to the second state to avoid accidental air intake during operation affecting the water production efficiency.

[0052] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
