[0024] Please see Figure 1 - Figure 9This utility model provides an embodiment of a detachable water dispenser filter structure, including a water dispenser body 1, an inner support 21, and a water supply mechanism. A support leg 4 is fixedly connected to the bottom of the water dispenser body 1. An opening / closing door 5 is rotatably connected inside the water dispenser body 1. The inner support 21 is fixedly connected inside the water dispenser body 1. A first fixing rod 22 is fixedly connected to the inner side of the inner support 21. A support wheel 23 is rotatably connected to the outer side of the first fixing rod 22. A connecting plate 24 is provided on the inner side of the inner support 21. A second fixing rod 25 is fixedly connected to the outer side of the connecting plate 24. A pulley 26 is rotatably connected to the outer side of the second fixing rod 25, and the pulley 26 is rolled on the inner side of the inner support 21. The filter cartridge can be moved to the outside of the water dispenser body 1 by pulling the connecting plate 24 to facilitate filter cartridge replacement. During use, the water supply mechanism discharges fully purified water to the outside of the water dispenser body 1. When the filter cartridge needs to be replaced, the opening and closing door 5 is opened, and the connecting plate 24 is pulled by hand. The connecting plate 24 drives the pulley 26 to rotate. The pulley 26 cooperates with the support wheel 23 to move the connecting plate 24 to the outside of the water dispenser body 1 for replacement. The inner bracket 21 has a guide rail on the pulley 26. The pulley 26 is rotatably connected to the inside of the guide rail. The guide rail guides the pulley 26 while limiting the rolling range of the pulley 26 to prevent the connecting plate 24 from detaching from the inner bracket 21.

[0025] Please see Figure 1 - Figure 6In this embodiment, a sleeve 27 is fixedly connected to the bottom of the connecting plate 24, and a fixed outer shell 28 is fixedly connected to the outside of the sleeve 27. A one-way valve body 29 is provided on the right side of the sleeve 27. A water inlet 210 is fixedly connected to the inside of the water dispenser body 1. A first water supply hose 211 is fixedly connected between the one-way valve body 29 and the water inlet 210. A knob 212 is rotatably connected inside the fixed outer shell 28. A gear 213 is fixedly connected to the outside of the knob 212. A connecting rod 214 meshes with the outside of the gear 213. A snap-fit ​​block 215 is fixedly connected to the outside of the connecting rod 214. The snap-fit ​​block 215 is slidably connected inside the fixed outer shell 28. A first spring 216 is fixedly connected between the snap-fit ​​block 215 and the fixed outer shell 28. A filter outer shell 217 is snap-fitted to the inside of the snap-fit ​​block 215. The housing 217 contains a filter cartridge body 218. A first spring 216 provides thrust, which makes the locking block 215 more securely engage with the filter housing 217. The filter cartridge body 218 then effectively purifies the water. The filter housing 217 has a slot at the relative position of the locking block 215. The locking block 215 engages with the inside of the slot. The engagement of the slot and the locking block 215 allows the filter housing 217 to be engaged with the inside of the sleeve 27, while also increasing the portability of the filter housing 217 for subsequent disassembly. The fixed housing 28 has a slide rail at the relative position of the locking block 215. The locking block 215 is slidably connected to the inside of the slide rail. The slide rail restricts the sliding of the locking block 215, preventing the locking block 215 from detaching from the fixed housing 28, thereby more securely engaging the filter housing 217.

[0026] Please see Figure 1 , Figure 7 - Figure 9In this embodiment, the water supply mechanism includes a water collection tank 31, which is slidably connected to the inner side of the water dispenser body 1. A grid plate 32 is fixedly connected inside the water collection tank 31. A two-way valve 33 is fixedly connected to the left side of the sleeve 27. A first water pump body 34 is provided inside the water dispenser body 1. A second water delivery hose 35 is fixedly connected between the two-way valve 33 and the first water pump body 34. A heater body 36 is provided inside the water dispenser body 1. A third connecting pipe 313 is fixedly connected between the first water pump body 34 and the heater body 36. A first water outlet 37 is fixedly connected inside the water dispenser body 1. A first connecting pipe 38 is fixedly connected between the first water outlet 37 and the heater body 36. The main body 1 of the water dispenser is equipped with a second water pump body 39. A third water supply hose 310 is fixedly connected between the two-way valve 33 and the second water pump body 39. A second water outlet 311 is fixedly connected inside the main body 1 of the water dispenser. A second connecting pipe 312 is fixedly connected between the second water outlet 311 and the second water pump body 39. The fully purified water is heated by a heater body 36 to achieve two water dispensing methods, which increases the practicality of the water dispenser. A sliding groove is opened in the main body 1 of the water dispenser at the relative position of the water collection tank 31. The water collection tank 31 is slidably connected inside the sliding groove. The water collection tank 31 collects the water splashed when the water is dispensed, preventing it from falling on the ground and requiring personnel to clean it.

[0027] During operation, water enters the sleeve 27 and filter housing 217 through the inlet 210 and the first water delivery hose 211. After the water is fully adsorbed by the three filter cartridges 218, it is diverted through the two-way valve 33. One part of the purified water is pumped by the first water pump 34, flows through the second water delivery hose 35 and the third connecting pipe 313 into the heater 36. After being heated by the heater 36, the first outlet 37 is opened, allowing the heated purified water to be discharged to the outside for drinking through the first connecting pipe 38. The other part of the water is pumped by the second water pump 39. When in use, the second outlet 311 is opened, and the purified water flows through the third water delivery hose 310 and the second connecting pipe 312 to be discharged to the outside for drinking. The filter cartridges need to be cleaned. When replacing the main body 218, open the opening and closing door 5, pull the connecting plate 24, and the connecting plate 24 drives the pulley 26 to roll, which moves the sleeve 27 and the filter housing 217 to the outside of the water dispenser main body 1. Turn the knob 212 to drive the gear 213 to rotate. Through the cooperation of the gear 213 and the connecting rod 214, the locking block 215 is driven to slide outward, so that the locking block 215 is disengaged from the filter housing 217. After that, the filter housing 217 is taken out to replace or clean the filter element body 218 inside the filter housing 217. Then, the filter housing 217 is put back into the sleeve 27. The first spring 216 provides a pushing force to push the locking block 215 to engage with the filter housing 217. Then, the connecting plate 24 is pushed back into the water dispenser main body 1, and the opening and closing door 5 is closed to complete the replacement.

[0028] By adding support wheels 23, connecting plates 24 and pulleys 26 through the above steps, the problem of inconvenience in disassembling and assembling the filter cartridge due to the small internal space of the water dispenser is solved, which affects the efficiency of disassembly and assembly work.
