Description

Technical Field

[0001] This utility model relates to the field of water purifier technology, specifically to a portable water purifier. Background Technology

[0002] A water purifier is a device specifically designed to remove impurities and contaminants from water, aiming to provide clean and safe drinking water and usable water. A portable water purifier, on the other hand, refers to a small water purifier with a relatively simple structure, small size, and easy to carry.

[0003] The existing patent publication number CN213885189U discloses a portable outdoor water purifier, including a water cup. A connecting rod is fixedly connected inside the water cup, and a base plate is fixedly connected to one end of the connecting rod. A filter cylinder is fixedly connected to the top of the base plate, and a fixing cylinder is fixedly connected to the top of the filter cylinder. A sealing plate is fixedly connected inside the water cup, and the sealing plate is fixedly connected to the outer surface of the fixing cylinder. The advantages of this utility model are: by setting the filter cylinder, when cleaning or replacing the composite filter element, since the inside of the fixing cylinder and the outer surface of the water outlet cylinder are both provided with matching threads, rotating the water outlet cylinder allows it to be removed. The diameter and thickness of the first filter cylinder are the same as the diameter and thickness of the fixing cylinder, allowing the composite filter element inside the third filter cylinder to be removed. After replacement, rotating the water outlet cylinder fixes the composite filter element between the base plate and the water outlet cylinder. The structure is simple and the operation is convenient.

[0004] The above solution has the following problems during implementation. The device uses a press pump to extract water containing impurities after it has been filtered through a filter cartridge and a composite filter element. However, it is not convenient to clean the filter cartridge during filtration. When the press pump draws water containing impurities, the impurities in the water may be adsorbed and adhere to the surface of the filter cartridge, causing the filter cartridge to become clogged and affecting the filtration efficiency, which greatly reduces the practicality of the device. Therefore, we provide a portable water purifier to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a portable water purifier that solves the problem that in the prior art, it is inconvenient to clean the filter cartridge during filtration. When water containing impurities is pumped in by pressing the pump, the impurities in the water are likely to be adsorbed and adhered to the surface of the filter cartridge, which will cause the filter cartridge to become clogged and affect the filtration efficiency, greatly reducing the practicality of the device.

[0006] This utility model provides the following technical solution: a portable water purifier, including a water cup, a sealing cap screwed onto the bottom of the water cup, a fixing cylinder installed at the top of the inside of the water cup, a suction component for pumping water installed on the upper side of the water cup through the fixing cylinder, a filter cylinder assembly installed at the bottom of the fixing cylinder, a composite filter element inserted inside the filter cylinder assembly, a support component for supporting the installation of the composite filter element at the bottom of the filter cylinder assembly, and a cleaning mechanism for cleaning the filter cylinder assembly inside the water cup.

[0007] The above technical solution, by setting up filter cartridges and composite filter elements, can filter water containing impurities.

[0008] As a preferred embodiment of the above technical solution, the suction assembly includes a water outlet cylinder, which is installed inside the fixed cylinder by a threaded insertion. A press pump is installed inside the water outlet cylinder, and a water outlet head is installed at the top of the press pump.

[0009] With the above technical solution, by pressing the pump with the water outlet, the water containing impurities inside the cup can be filtered sequentially through the filter cylinder assembly and the composite filter element, then enter the water outlet cylinder, and finally flow out from the water outlet, making it easier to extract the filtered water.

[0010] As a preferred embodiment of the above technical solution, the cleaning mechanism includes two sets of connecting rods and two sets of disassembly and assembly components. Both sets of connecting rods are located on the inner sides of the water cup. Each set of connecting rods has a connecting block connected to its bottom end. A cleaning brush is installed between the two sets of connecting blocks through the two sets of disassembly and assembly components, and the cleaning brush is sleeved on the outside of the filter cartridge assembly.

[0011] The above technical solution enables the cleaning brush to clean the surface of the filter cartridge assembly, removing impurities adsorbed on the surface of the filter cartridge assembly, thus better preventing the filter cartridge assembly from being blocked, and allowing for smoother filtration of water containing impurities.

[0012] As a preferred embodiment of the above technical solution, the top ends of both sets of connecting rods are disposed through the top end of the water cup, and a connecting plate is installed at the top end of both sets of connecting rods.

[0013] The above technical solution makes it more convenient to move the connecting rod simultaneously by pulling the connecting plate.

[0014] As a preferred embodiment of the above technical solution, each set of disassembly and assembly components includes a sliding groove, each set of sliding grooves is opened at one end of the connecting block near the cleaning brush, each set of sliding grooves has a spring installed on its inner side, each set of sliding grooves has a limit block slidably installed at its opening, and the inner end of the limit block is connected to the spring, each set of cleaning brush outer wall has a limit groove on both sides, each set of limit blocks is inserted into the limit groove, and each set of limit blocks has a prying block installed at its top.

[0015] The above technical solution allows the cleaning brush to be detached from the two connecting blocks. Finally, by pulling the cleaning brush, it can be pulled out from the surface of the filter cartridge assembly, making it easier to remove the cleaning brush from inside the water cup. This makes it easier to clean or replace the cleaning brush.

[0016] As a preferred embodiment of the above technical solution, the support assembly includes a base plate and two sets of L-shaped grooves. The base plate is fitted to the bottom end of the filter cylinder assembly, and support rods are connected to both sides of the side end of the base plate. The two sets of L-shaped grooves are opened on both sides of the inner wall of the water cup, and each set of support rods is inserted and locked in the L-shaped groove.

[0017] The above technical solution allows the composite filter element to be fixed between the base plate and the water outlet cylinder by installing the base plate, making the composite filter element more stable. Then, by rotating the base plate, the support rod can slide horizontally within the L-shaped groove until it aligns with the vertical part of the L-shaped groove. This allows the base plate to be removed from the inside of the water cup, enabling the composite filter element to be disassembled and replaced, thus ensuring that the filtered water remains cleaner.

[0018] As a preferred embodiment of the above technical solution, the outer wall of the water cup is rotatably fitted with a handle.

[0019] The above technical solution allows the device to be lifted by a handle, making it easy to carry and move.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] This invention, by setting up a filter cartridge assembly and a composite filter element, can filter water containing impurities. By setting up a cleaning mechanism, the surface of the filter cartridge assembly can be cleaned during filtration, removing impurities adsorbed on the surface of the filter cartridge assembly, thus better preventing the filter cartridge assembly from being blocked and allowing for smoother filtration of water containing impurities. In addition, by setting up a disassembly and assembly component, the cleaning brush can be disassembled, making it easy to clean or replace the cleaning brush, greatly increasing the practicality of the device.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] like Figures 1-4 As shown, this utility model provides a technical solution: a portable water purifier, including a water cup 1, a sealing cap 11 screwed onto the bottom of the water cup 1, a fixing cylinder 2 installed at the top of the inside of the water cup 1, a suction assembly 3 for pumping water installed on the upper side of the water cup 1 through the fixing cylinder 2, a filter cylinder assembly 21 installed at the bottom of the fixing cylinder 2, a composite filter element 22 inserted inside the filter cylinder assembly 21, a support assembly 4 for supporting the installation of the composite filter element 22 provided at the bottom of the filter cylinder assembly 21, a cleaning mechanism 5 for cleaning the filter cylinder assembly 21 provided inside the water cup 1, and the suction assembly 3 including a water outlet cylinder 31. The water outlet cylinder 31 is installed inside the fixed cylinder 2 by a threaded insertion. A press pump 32 is installed inside the water outlet cylinder 31, and a water outlet head 33 is installed at the top of the press pump 32. This structure allows the press pump 32 to be pressed by the water outlet head 33, so that the water containing impurities in the water cup 1 can be filtered sequentially through the filter cylinder group 21 and the composite filter element 22, and then enter the water outlet cylinder 31, and finally flow out from the water outlet head 33, making it easier to extract the filtered water. A handle 12 is rotatably installed on the outer wall of the water cup 1, so that the device can be lifted by the handle 12, making it easy to carry and move the device.

[0029] It should be noted that the press pump 32 is existing technology. Its principle is to use compression force to discharge liquid or gas from a container. It is a common structure in daily life, so it is not described in detail.

[0030] As one implementation method in this embodiment, such as Figure 2 and Figure 4As shown, the cleaning mechanism 5 includes two sets of connecting rods 51 and two sets of disassembly and assembly components 6. Both sets of connecting rods 51 are located on the inner sides of the water cup 1. Each set of connecting rods 51 has a connecting block 52 connected to its bottom end. A cleaning brush 53 is installed between the two sets of connecting blocks 52 through the two sets of disassembly and assembly components 6. The cleaning brush 53 is sleeved on the outside of the filter cartridge assembly 21. This structure allows pulling the connecting rods 51 to drive the connecting blocks 52, and the connecting blocks 52 to drive the cleaning brush 53 to slide along the outer wall surface of the filter cartridge assembly 21. This can clean the surface of the filter cartridge assembly 21 and remove the impurities adsorbed on the surface of the filter cartridge assembly 21, thus better preventing the filter cartridge assembly 21 from being blocked and allowing for smoother filtration of water containing impurities. The top ends of both sets of connecting rods 51 are set through the top end of the water cup 1. A connecting plate 54 is installed at the top end of both sets of connecting rods 51, so that pulling the connecting plate 54 can simultaneously move the connecting rods 51, making it more convenient.

[0031] As one implementation method in this embodiment, such as Figure 3 and Figure 4 As shown, each set of disassembly and assembly components 6 includes a sliding groove 61. Each set of sliding grooves 61 is opened at one end of the connecting block 52 near the cleaning brush 53. A spring 62 is installed inside the sliding groove 61. A limit block 63 is slidably installed at the opening of each set of sliding grooves 61, and the inner end of the limit block 63 is connected to the spring 62. Limit grooves 64 are opened on both sides of the outer wall of the cleaning brush 53. Each set of limit blocks 63 is inserted into the limit groove 64. The top of each set of limit blocks 63 is... Each set is equipped with a lever 65. This structure allows the lever 65 to be turned so that the two sets of limiting blocks 63 can be pulled out from the two sets of limiting grooves 64 and moved into the slide groove 61 to compress the spring 62. At this time, the cleaning brush 53 can be removed from between the two sets of connecting blocks 52. Finally, the cleaning brush 53 is pulled out from the surface of the filter cartridge assembly 21, and the cleaning brush 53 can be removed from the inside of the water cup 1, making it easier to clean or replace the cleaning brush 53.

[0032] As one implementation method in this embodiment, such as Figure 4 As shown, the support assembly 4 includes a base plate 41 and two sets of L-shaped grooves 43. The base plate 41 is fitted to the bottom end of the filter cartridge assembly 21. Support rods 42 are connected to both sides of the side end of the base plate 41. The two sets of L-shaped grooves 43 are opened on both sides of the inner wall of the water cup 1. Each set of support rods 42 is inserted and locked in the L-shaped groove 43. This structure allows the composite filter element 22 to be fixed between the base plate 41 and the water outlet cylinder 31 by installing the base plate 41, making the composite filter element 22 more stable. Then, by rotating the base plate 41, the support rods 42 can slide horizontally in the L-shaped grooves 43 until the support rods 42 are rotated to correspond to the vertical part of the L-shaped grooves 43. Then the base plate 41 can be removed from the inside of the water cup 1, so that the composite filter element 22 can be disassembled and replaced, so that the filtered water can be kept cleaner.

[0033] Working principle: To filter and purify water containing impurities, simply open the sealing cap 11, fill the water cup 1 with the water containing impurities, and then close the sealing cap 11. At this time, press the pump 32 through the water outlet 33. This will allow the water containing impurities in the water cup 1 to pass through the filter cylinder assembly 21 and the composite filter element 22 in sequence for filtration, and then enter the water outlet cylinder 31. Finally, it will flow out from the water outlet 33, thus completing the purification and filtering out the water containing impurities. At the same time, if impurities clog the filter cylinder assembly 21 during filtration, affecting the filtration, the connecting plate 54 can be pulled to drive the connecting rod 51. The connecting rod 51 drives the connecting block 52, and the connecting block 52 drives the cleaning brush 53 to slide along the outer wall surface of the filter cylinder assembly 21. This will clean the surface of the filter cylinder assembly 21, remove the impurities adsorbed on the surface of the filter cylinder assembly 21, better prevent the filter cylinder assembly 21 from being blocked, and thus filter the water containing impurities more smoothly.

[0034] To replace the composite filter element 22, simply open the sealing cover 11, then rotate the base plate 41 to slide the support rod 42 laterally within the L-shaped groove 43 until the support rod 42 aligns with the vertical portion of the L-shaped groove 43. This allows the base plate 41 to be removed from the inside of the water cup 1. The old composite filter element 22 can then be pulled out of the filter cartridge assembly 21, and a new composite filter element 22 can be installed for replacement. Simultaneously, after the base plate 41 is removed, move the two sets of levers 65 to pull the two sets of limiting blocks 63 out of the two sets of limiting grooves 64 and move them into the slide groove 61 to compress the spring 62. At this point, the cleaning brush 53 can be removed from between the two sets of connecting blocks 52. Finally, pull the cleaning brush 53 to pull it out from the surface of the filter cartridge assembly 21, allowing the cleaning brush 53 to be removed from the inside of the water cup 1, thus facilitating cleaning or replacement of the cleaning brush 53.

[0035] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
