Bacteriostatic antibacterial fiber activated carbon composite filter element

Abstract

This utility model discloses an antibacterial and antimicrobial fiber activated carbon composite filter element, relating to the field of filter element technology. It includes a PP inner skeleton, with an activated carbon fiber layer fixedly sleeved on the surface of the PP inner skeleton, and a PP cotton filter element fixedly sleeved on the surface of the activated carbon fiber layer. The device utilizes a sliding rod, slider, and spring-assisted structure. During the user's tightening of the water purifier lid, the base plate is pressed, driving the sliding rod and slider, and compressing the spring to store energy. After installation, the spring continuously applies a reset pressure to the base plate, thereby pushing the connecting sleeve to always tightly adhere to the sealing gasket of the water purifier's filter chamber outlet. This structure effectively compensates for sealing gaps caused by water flow fluctuations, component wear, or temperature changes, significantly improving the long-term sealing stability of the connection, preventing unfiltered water from flowing out, and ensuring that water flows entirely through the interior of the filter material, thereby improving the overall filtration reliability and safety of the water purification system.

Description

Technical Field

[0001] This utility model belongs to the field of filter technology, and specifically relates to an antibacterial fiber activated carbon composite filter. Background Technology

[0002] As people's living standards improve, they are paying more and more attention to the quality of drinking water. Household water purifiers have become an essential facility for many families. The core function of a water purifier depends on its internal filter cartridge components. Among them, composite filter cartridges are widely used because they can integrate multiple filter materials. The filter cartridge needs to form a sealed connection with the water outlet of the water purifier's filter chamber to ensure that all the water to be filtered can completely pass through the filter material and avoid leakage of unfiltered water, which is the so-called water leakage phenomenon.

[0003] Currently, most filter cartridges rely on the static pressure generated by manually tightening the cap during installation to seal the water outlet. This pressure can weaken over long-term use due to fluctuations in water system pressure, aging of gaskets, wear of parts, or thermal expansion and contraction caused by temperature changes, leading to poor sealing and the risk of leakage at the interface. To solve the above problems, we provide an antibacterial and antimicrobial fiber activated carbon composite filter cartridge. Utility Model Content

[0004] The purpose of this utility model is to provide an antibacterial and antimicrobial fiber activated carbon composite filter element to solve the problem mentioned in the background art that the sealing of most filter elements and water outlets relies on the static pressure generated by manually tightening the cap during installation. This pressure will weaken during long-term use due to water system pressure fluctuations, aging of sealing gaskets, wear of parts, or thermal expansion and contraction caused by temperature changes, thus causing poor sealing and water leakage at the interface.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an antibacterial and antimicrobial fiber activated carbon composite filter element, comprising a PP inner skeleton, an activated carbon fiber layer fixedly sleeved on the surface of the PP inner skeleton, a PP cotton filter element fixedly sleeved on the surface of the activated carbon fiber layer, a folded outer layer fixedly sleeved on the surface of the PP cotton filter element, a bottom shell provided at the bottom of the PP inner skeleton, a fixing plate provided at the bottom of the bottom shell, a sliding rod slidably sleeved inside the fixing plate, a slider fixedly connected to the top of the sliding rod, and a spring provided inside the bottom shell.

[0006] Preferably, a mesh sleeve is fixedly fitted onto the surface of the folded outer layer, and the bottom of the mesh sleeve is fixedly fitted onto the bottom shell.

[0007] Preferably, the top of the mesh sleeve is fixedly sleeved with the top shell, the top shell has a water outlet hole inside, and a connecting sleeve is fixedly connected to the top of the top shell.

[0008] Preferably, the bottom of the slide bar is fixedly connected to a base plate, and the top of the base plate has an internal groove that matches the fixed plate.

[0009] Preferably, the fixing plate is fitted with mounting bolts inside, and the top of the mounting bolts is threadedly connected to the bottom shell.

[0010] This utility model has the following beneficial effects: This device employs a cooperative structure of a sliding rod, a slider, and a spring. As the user tightens the water purifier lid, the base plate is pressed, causing the sliding rod and slider to move and the spring to compress and store energy. After installation, the spring continuously applies a reset pressure to the base plate, thereby pushing the connecting sleeve to always fit tightly against the sealing gasket of the water purifier's filter compartment outlet. This structure effectively compensates for sealing gaps caused by water flow fluctuations, component wear, or temperature changes, significantly improving the long-term sealing stability of the connection, preventing unfiltered water from flowing out, and ensuring that the water flows entirely through the interior of the filter media, thereby improving the filtration reliability and safety of the overall water purification system.

[0013] The present invention will be further described in detail below with reference to the accompanying drawings.

[0014] Example 1: refer to Figure 1-4 An antibacterial and antimicrobial fiber activated carbon composite filter element includes a PP inner skeleton 1, an activated carbon fiber layer 2 fixedly sleeved on the surface of the PP inner skeleton 1, a PP cotton filter element 3 fixedly sleeved on the surface of the activated carbon fiber layer 2, a folded outer layer 11 fixedly sleeved on the surface of the PP cotton filter element 3, a bottom shell 4 provided at the bottom of the PP inner skeleton 1, a fixing plate 5 provided at the bottom of the bottom shell 4, a sliding rod 6 slidably sleeved inside the fixing plate 5, a slider 7 fixedly connected to the top of the sliding rod 6, and a spring 8 provided inside the bottom shell 4.

[0015] Specifically, the PP inner skeleton 1 has a filtration precision of five microns, mainly intercepting micro-particulate matter in the water. The activated carbon fiber layer 2 mainly treats bacteria and organic pollutants, the folded outer layer 11 mainly intercepts bacteria and viruses, and the PP cotton filter element 3 mainly treats suspended solids, flocculants, odors, and rust in the water. Through the cooperative structure of the sliding rod 6, slider 7, and spring 8, when the user tightens the water purifier lid, the base plate 9 is pressed, which drives the sliding rod 6 and slider 7 and compresses the spring 8 to store energy. After installation, the spring 8 continuously applies a reset pressure to the base plate 9, thereby pushing the connecting sleeve 15 to always fit tightly against the sealing gasket of the water purifier filter chamber outlet. This structure can effectively offset the sealing gaps caused by water flow fluctuations, component wear, or temperature changes, significantly improve the long-term sealing stability of the connection, prevent water from flowing out unfiltered, and ensure that the water flows completely through the inside of the filter material, thereby improving the filtration reliability and safety of the overall water purification system.

[0016] refer to Figure 1 A mesh sleeve 12 is fixedly fitted onto the surface of the folded outer layer 11. The bottom of the mesh sleeve 12 is fixedly fitted onto the bottom shell 4. By setting the mesh sleeve 12, the folded outer layer 11 can be effectively tightened, thereby increasing the filtration accuracy.

[0017] refer to Figure 4 The top of the mesh sleeve 12 is fixedly sleeved with the top shell 13. The top shell 13 has a water outlet hole 14 inside. The top of the top shell 13 is fixedly connected with a connecting sleeve 15. By setting the connecting sleeve 15, the device can be fitted with the sealing gasket of the water outlet of the water purifier filter chamber.

[0018] refer to Figure 3 The bottom of the slide bar 6 is fixedly connected to the base plate 9, and the top of the base plate 9 is provided with an internal groove 16 that is compatible with the fixed plate 5.

[0019] refer to Figure 3 The mounting plate 5 is fitted with mounting bolts 10 inside. The top of the mounting bolts 10 is threaded to the bottom shell 4. By setting the mounting bolts 10, the mounting plate 5 can be effectively installed.

[0020] Brief description of usage: The user places the device into the water purifier, ensuring that the connecting sleeve 15 fits against the sealing gasket of the water purifier's filter compartment outlet. Then, the user screws on the water purifier lid to apply pressure to the base plate 9, causing the base plate 9 to slide the sliding rod 6 inside the fixed plate 5. The sliding rod 6 drives the slider 7 to compress and store energy in the spring 8. After the water purifier lid is installed, the spring 8 continues to apply pressure to the base plate 9 to reset, thereby effectively improving the sealing between the connecting sleeve 15 and the filter compartment outlet.
