[0017] (III) Beneficial effects

[0018] The present utility model provides an RO double-stage water treatment device, which has the following beneficial effects:

[0019] 1. For this RO double-stage water treatment device, through the settings of the limiting component, the support frame and the clamping ring, during use, the reverse osmosis filter cartridge is closely attached to the inside of the support frame, and then the clamping ring is pulled to clamp the reverse osmosis filter cartridge. The clamping rod is pulled, so that the rotating bolt rotates on one side of the clamping ring. When the clamping rod is horizontally inserted into the clamping groove on one side of the support frame and the clamping ring, the clamping rod is then rotated downward and inserted into the groove on the clamping groove, thereby achieving the effect of quickly positioning and installing the reverse osmosis filter cartridge, simplifying the process of installing the reverse osmosis filter cartridge, and improving the convenience of the RO double-stage water treatment device.

[0020] 2. For this RO double-stage water treatment device, through the setting of the buckle component, during use, the high-pressure water pump drives the liquid into the filter sleeve, and the large-particle substances in the liquid are removed through the activated carbon filter screen. At the same time, when the activated carbon filter screen needs to be replaced, the rotating frame is pulled to rotate on the support plate, and the rotating sleeve pushes the pull rod to lift, and then it is disengaged from the limiting piece, and the top cover is opened, thereby achieving the effect of quickly replacing the activated carbon filter screen, preventing the impurity accumulation of the activated carbon filter screen during long-term use, resulting in a decline in the filtering effect and damage to the reverse osmosis filter cartridge, and improving the service life of the RO double-stage water treatment device.

[0021] 3. For this RO double-stage water treatment device, through the setting of the pressure relief component, during use, when the internal pressure of the reverse osmosis filter cartridge is too high, the liquid pressure reaches the discharge pipe through the connecting pipe, and the pressure air flow passes through the fixing piece and pushes the piston upward, so that the piston pulls the tension spring to deform. The limiting rod slides on the fixing piece, and the pressure air flow bypasses the piston and passes through the cavity and is discharged. When the pressure is stable, the tension spring restores its deformation, pulls the piston to contract and block the discharge pipe, thereby achieving the effect of discharging the excess liquid pressure, preventing the internal pressure of the reverse osmosis filter cartridge from being too high and causing damage to the reverse osmosis filter membrane, and improving the safety.

[0037] In the present utility model, the working steps of the device are as follows:

[0038] The first step: When in use, place the reverse osmosis filter cartridge 6 closely against the inside of the support frame 3, and then pull the snap ring 4 to clamp the reverse osmosis filter cartridge 6.
