[0002] A filter element is a device used to filter impurities, dust, particulate matter, and other contaminants from air, liquids, or gases. It is widely used in air purification, drinking water treatment, and industrial equipment. Through specific materials and structures, it captures contaminants, ensuring the cleanliness of the fluid and the normal operation of the equipment.

[0003] However, the filter cartridges used in existing water dispensers have shortcomings. First, after prolonged use, the pores of existing filter cartridges are easily clogged by particulate impurities, requiring frequent cleaning and replacement. Second, existing filter cartridges are generally housed in a canister-like outer shell, requiring the tightened canister cap to be unscrewed during replacement, which is laborious and inconvenient. Therefore, a composite functional filter cartridge is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a composite functional filter element, which aims to improve the problem that the filter pores of existing filter elements are easily clogged by particulate impurities after long-term use, requiring frequent cleaning and replacement. In addition, the existing filter elements require unscrewing the tightened cap when replacing them, which is laborious and inconvenient.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-3 This utility model provides an embodiment of a composite functional filter element, comprising a tank 1 for assembling the filter element, with a certain space between the inner wall of the tank 1 and the filter element for the passage of filtered water. A core 2 is fitted inside the tank 1 to block particulate impurities in the water, thereby improving water quality. A tank lid 3 is fitted to the top of the tank 1 to seal it. An annular groove 11 is formed at the top of the inner wall of the tank 1, and several springs 12 are uniformly fixedly connected to the top of the inner wall of the annular groove 11. A connecting ring 13 is fixedly connected to the bottom of the tank 12, and a sealing ring 14 is fixedly connected to the bottom of the connecting ring 13. Under the action of the elastic force of several springs 12, the sealing ring 14 will move downward. Both sides of the top of the tank 1 are equipped with a locking assembly, and both sides of the tank cover 3 are provided with a latch 10 for locking the position of the tank cover 3. A flow switch 15 is fixedly connected to one side of the top of the tank 1, which can detect the flow rate of the filtered water. An indicator light 16 is fixedly installed on the top of the front of the tank 1, which serves as an indication and reminder by lighting up the light.

[0032] Reference Figure 3The locking assembly includes a groove 7, a spring 8, and a locking block 9. The groove 7 is located on one side of the top of the canister 1. The inner wall of the groove 7 is fixedly connected to the spring 8, and one end of the spring 8 is fixedly connected to the locking block 9. By simultaneously locking the locking blocks 9 on both sides of the canister cover 3, the elastic force of the spring 8 is overcome, and the locking block 9 is pressed into the groove 7, thereby unlocking and removing the canister cover 3, making the filter replacement operation convenient and labor-saving.

[0033] Reference Figure 4 The core 2 includes a stainless steel mesh cylinder 201, a PP cotton layer 202, an activated carbon layer 203, and an annular cavity 204. The stainless steel mesh cylinder 201 is engaged with the inner wall of the tank 1, and uses the stainless steel mesh cylinder 201 to block large particulate impurities in the water, protecting the subsequent filter layer from being blocked by large particulate impurities. The stainless steel mesh cylinder 201 has an annular cavity 204 inside, and the inner wall of the annular cavity 204 is fixedly connected to the PP cotton layer 202, which filters smaller particulate matter in the water, effectively removing fine impurities in the water. The outer wall of the PP cotton layer 202 is fixedly connected to the activated carbon layer 203, which adsorbs harmful substances and odors in the water.

[0034] Reference Figure 1 The bottom of the tank 1 is fixedly connected to the water inlet 4. The water to be purified is input into the tank 1 through the water inlet 4 and flows into the internal area of ​​the core 2.

[0035] Reference Figure 1 One end of the flow switch 15 is fixedly connected to the water outlet 5. The filtered water will pass through the core 2 and be discharged from the water outlet 5 through the flow switch 15.

[0036] Reference Figure 1 The indicator light 16 is electrically connected to an external power supply via the flow switch 15. When the external power supply is turned on, during water use, if the water flow rate is lower than the set value due to filter blockage, the flow switch 15 will automatically control the indicator light 16 to light up, which can play a better reminder effect and allow the filter to be replaced in time.

[0037] Reference Figure 2 Rubber rings 6 are fixedly connected to the top and bottom of the core 2. The rubber rings 6 can improve the sealing effect between the core 2 and the tank 1 and the tank cover 3, and prevent unfiltered water from being discharged from the gaps.

[0038] Reference Figure 3 One end of the locking block 9 engages with the inner wall of the locking slot 10, which acts as a lock and can fix the position of the can lid 3.

[0039] Reference Figure 3 The bottom end of the sealing ring 14 abuts against the top end of the tank 1, thereby ensuring the sealing effect of the filter element shell and preventing water penetration due to insufficient clamping structure.

[0040] Working principle: Water to be purified enters the tank 1 through the inlet 4. After entering the middle of the core 2, the stainless steel mesh 201 first blocks large particles of impurities, protecting the subsequent filter layers from clogging. Then, the PP cotton layer 202 filters smaller particles, effectively removing fine impurities. Finally, the activated carbon layer 203 adsorbs harmful substances and odors. This results in lower filtration pressure for each filter layer, reducing the frequency of filter cleaning and replacement. The filtered water passes through the core 2 and is discharged from the outlet 5 via the flow switch 15 (model FLS-1). 01. During water use, when the water flow rate is lower than the set value due to filter blockage, the flow switch 15 will automatically control the indicator light 16 to light up, which can play a better reminder effect and replace the filter in time. The sealing ring 14 is set inside the can lid 3. Under the action of several springs 12, it will move downward and press tightly against the top of the can body 1, thereby ensuring the sealing effect of the filter shell. The sealing ring 14 is made of rubber. By simultaneously using the locking blocks 9 on both sides of the can lid 3 to overcome the elasticity of the spring 8, the locking blocks 9 are pressed into the groove 7, which can unlock and remove the can lid 3, making the filter replacement operation convenient and labor-saving.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
