Specific embodiments
[0024] A water purifier with a filter element detection function:
[0025] As Figures 1-4 shown, in this embodiment, it includes a device body 1 and a filter cartridge 3. An installation cavity 2 with an open front end is opened in the upper part of the device body 1. The filter cartridge 3 is arranged in the installation cavity 2. Both the left and right ends of the filter cartridge 3 are communicated with an internal threaded pipe 8. An external threaded pipe 9 is threadedly connected inside each internal threaded pipe 8. The right end of the external threaded pipe 9 on the right is communicated with a first connecting ring 6. A first rotating ring 5 is arranged to the right of the first connecting ring 6. A first telescopic pipe 7 is communicated between the first rotating ring 5 and the first connecting ring 6. Spring pull rods 15 are arranged at both the upper and lower ends of the first telescopic pipe 7 and are connected between the first rotating ring 5 and the first connecting ring 6. A spring pressure rod 11 fixed to the bottom end inside the installation cavity 2 is arranged at the lower left of the first connecting ring 6. A pressure sensor 12 is connected to the end of the spring pressure rod 11. The sensing end of the pressure sensor 12 is close to the lower left end of the first connecting ring 6. A water storage chamber 23 is opened in the device body 1. A water passing connection assembly is arranged at the left end of the filter cartridge 3. The water passing connection assembly includes a second connecting ring 14, a second rotating ring 13, a water inlet pipe 16, a second telescopic pipe 17 and two spring return rods 18. The second connecting ring 14 is communicated with the left side of the external threaded pipe 9 at the left end. The second rotating ring 13 is arranged to the left of the second connecting ring 14. The water inlet pipe 16 is communicated between the second rotating ring 13 and the water storage chamber 23, and the water inlet pipe 16 is fixedly connected to the device body 1. The second rotating ring 13 is rotatably connected to the water inlet pipe 16. The second telescopic pipe 17 is communicated between the second connecting ring 14 and the second rotating ring 13. The spring return rods 18 are connected between the second connecting ring 14 and the second rotating ring 13. The right end of the first rotating ring 5 is rotatably connected and communicated with a water inlet pipe 4. The water inlet pipe 4 is fixedly penetrated through the right side of the device body 1 to the right. A water outlet valve 24 communicated with the water storage chamber 23 is connected to the lower right end of the device body 1.
[0026] When the water purifier is in use, water enters the filter cartridge 3 through the water inlet pipe 4, the first rotating ring 5, the first telescopic pipe 7, the first connecting ring 6 and the corresponding external thread pipe 9. Then, the water is filtered by the filter cartridge 3. The filtered water enters the water storage chamber 23 through the water inlet pipe 16, and the purified and filtered water is stored in the water storage chamber 23. Finally, the water in the water storage chamber 23 is discharged for use through the water outlet valve 24. When the filter cartridge 3 is continuously blocked, due to the increasing water resistance during the filtration of the filter cartridge 3, that is, the water filtration performance of the filter cartridge 3 decreases due to blockage, the filter cartridge 3 will drive the internal thread pipe 8 and the internal and external thread pipe 9 to move to the left. At this time, the second connecting ring 14 will compress the spring return rod 18 and the second telescopic pipe 17, and the first connecting ring 6 will stretch the spring pull rod 15 and the first telescopic pipe 7. At the same time, the first connecting ring 6 will squeeze the pressure sensor 12, and the pressure sensor 12 will compress the spring pressure rod 11. The more serious the blockage of the filter cartridge 3 is, the greater the pressure received by the pressure sensor 12 is, that is, the greater the pressure value detected by the pressure sensor 12 is. On the premise that the pressure sensor 12 is set to be signal-connected to the pressure display screen 19, the pressure value is then displayed through the pressure display screen 19. Therefore, it is beneficial to detect the blockage degree of the filter cartridge 3 in real time.
[0027] As Figure 1 , 2 shown, in this embodiment, a touch switch 21 fixed to the top end inside the installation cavity 2 is provided above the left upper part of the first connecting ring 6, and the upper part of the front end of the device body 1 is connected with a pressure display screen 19 and an audible and visual alarm 20.
[0028] When the filter cartridge 3 is severely blocked and the first connecting ring 6 presses to activate the touch switch 21, on the premise that the touch switch 21 is set to be connected in series with the audible and visual alarm 20, after the touch switch 21 is activated, it will control the audible and visual alarm 20 to be powered on and work, and the touch switch 21 will control the audible and visual alarm 20 to light up and emit an alarm sound. At this time, it means that the filter cartridge 3 is severely blocked and needs to be cleaned and maintained. The user can timely discover that the filter cartridge 3 needs to be cleaned and maintained through the lighting and alarm sound of the audible and visual alarm 20, so as to clean and maintain the filter cartridge 3 in time.
[0029] As Figures 1-4 shown, in this embodiment, a cover plate 22 covering the installation cavity 2 is fixed to the front end of the device body 1 by bolts. A first rotating ring 5 is provided on the right side of the first connecting ring 6. The second connecting ring 14 communicates with the left side of the left end external thread pipe 9. A second rotating ring 13 is provided on the left side of the second connecting ring 14. The water inlet pipe 16 communicates between the second rotating ring 13 and the water storage chamber 23, and the water inlet pipe 16 is fixedly connected to the device body 1. The second rotating ring 13 is rotatably connected to the water inlet pipe 16. The second telescopic pipe 17 communicates between the second connecting ring 14 and the second rotating ring 13. The spring return rod 18 is connected between the second connecting ring 14 and the second rotating ring 13.
[0030] When it is necessary to clean and maintain the filter cartridge 3, remove the cover plate 22, and then loosen the external thread pipe 9 by rotating the first rotating ring 5 and the second rotating ring 13 until the external thread pipe 9 is thread-separated from the internal thread pipe 8. Then, push the first connecting ring 6 to compress the first telescopic pipe 7 and the spring pull rod 15, or push the second connecting ring 14 to compress the second telescopic pipe 17 and the spring return rod 18, so that the external thread pipe 9 can be conveniently removed from the internal thread pipe 8, achieving the effect of conveniently disassembling the filter cartridge 3. Therefore, the filter cartridge 3 can be conveniently cleaned and maintained.
[0031] As Figures 1-3 shown, in this embodiment, a first rotating ring 5 is provided on the right side of the first connecting ring 6, the second connecting ring 14 communicates with the left side of the left-end external thread pipe 9, the second rotating ring 13 is provided on the left side of the second connecting ring 14, the water inlet pipe 16 communicates between the second rotating ring 13 and the water storage chamber 23, and the water inlet pipe 16 is fixedly connected to the container body 1. The second rotating ring 13 is rotatably connected to the water inlet pipe 16. The second telescopic pipe 17 communicates between the second connecting ring 14 and the second rotating ring 13. The spring return rod 18 is connected between the second connecting ring 14 and the second rotating ring 13. Sealing rings 10 are provided between the external thread pipe 9 and the filter cartridge 3. The opening at the end of the internal thread pipe 8 is "funnel-shaped".
[0032] When it is necessary to install the filter cartridge 3 after cleaning and maintenance, push the first connecting ring 6 to compress the first telescopic pipe 7 and the spring pull rod 15, or push the second connecting ring 14 to compress the second telescopic pipe 17 and the spring return rod 18. Since the opening at the end of the internal thread pipe 8 is funnel-shaped, the external thread pipe 9 can be conveniently inserted into the internal thread pipe 8. Then, the elastic force of the spring pull rod 15 will drive the first connecting ring 6 to reset, and the return elastic force of the spring return rod 18 will drive the second connecting ring 14 to reset. Therefore, the elastic force will drive the external thread pipe 9 to abut against the inside of the internal thread pipe 8, so that the filter cartridge 3 can be elastically clamped. Then, rotate the first rotating ring 5 and the second rotating ring 13 in sequence until the external thread pipe 9 is thread-connected to the internal thread pipe 8. Since the sealing ring 10 is provided between the thread pipe and the filter cartridge 3, at this time, the sealing ring 10 is pressed tightly between the filter cartridge 3 and the external thread pipe 9. Therefore, the sealing ring 10 is beneficial to seal the connection between the external thread pipe 9 and the internal thread pipe 8 to prevent water leakage at the connection, so that the disassembled filter cartridge 3 can be conveniently installed and used.
