Reverse osmosis (English: Reverse osmosis, referred to as RO), mainly through the principle of reverse osmosis, the impurity in the water quality is removed by means of the RO membrane interception under the pressure drive, so as to obtain clean water. The osmotic pressure of the general household RO membrane is about It is 5-6kg/cm2 (70-80psi), so it is necessary to use the motor to increase the water pressure to facilitate the reverse osmosis function of the RO membrane. However, due to the problem of water quality, the RO membrane will face serious clogging problems. When the RO membrane is clogged, it will cause faucets. The amount of water attenuates, and the amount of water that has not passed through the RO membrane accumulates in the pipeline. At this time, the motor continues to output water supply pressure, which will cause problems such as diaphragm separation and damage. However, the motor is prone to high temperature due to continuous high-voltage operation, which will cause transformers, Bearings, plastic gaskets and other parts are damaged.

Therefore, some businessmen have developed such as Taiwan's new No. M592786 patent, which provides a reverse osmosis water purifier without a pressurized motor, which includes a pipeline assembly, a filter element group and a reverse osmosis membrane, and the pipeline assembly has a The water inlet end is connected to the water source for water input, and the pipeline assembly has a water outlet end for the output of water flowing through the pipeline assembly, and the pipeline assembly is not connected to the pressurized DC motor. The filter element group is connected to the pipeline assembly and is located between the water inlet end and the water outlet end, and the water input from the water inlet end flows into the filter element group to be filtered and then flows out. The reverse osmosis membrane is connected to the pipeline assembly and is located between the filter element group and the water outlet. The water flowing out of the filter element group flows into the reverse osmosis membrane for filtration, and then flows out to the water outlet for output. The reverse osmosis membrane is the same If the output flow is several times larger than the reverse osmosis membrane pressurized by the pressurized motor, the reverse osmosis water purifier further includes a water flow control unit, the water flow control unit includes an automatic controller, and is connected to the pipeline One of the components, the water source pressure detection switch, a full water pressure switch, a first solenoid valve and a second solenoid valve are electrically connected to the automatic controller respectively, wherein the water source pressure detection switch is connected in series between the first filter element and the water inlet The full water pressure switch is connected in series between the third filter element and the water outlet, the first solenoid valve is connected in series between the first filter element and the water source pressure detection switch, and the second solenoid valve is connected in series between the reverse osmosis membrane and the Between the waste water output ends, the second solenoid valve is connected in parallel with the waste water ratio.

The following is a detailed description of the characteristics of this creation by means of implementation. First, please refer to Figure 1, which is a DC motor voltage stabilizing system for a reverse osmosis water purifier, which includes: a pre-filter device 1, a DC motor 2, a Reverse osmosis filter 3, a water outlet device 4; And a pipeline 5 connecting the above-mentioned components; Wherein, a sensor 6 is provided in the pipeline 5 connecting the DC motor 2 and the reverse osmosis filter 3, the sensor 6. The signal is transmitted to a controller 7 through an electrical connection. After receiving the signal from the sensor 6, the controller 7 can immediately adjust the speed of the DC motor 2 to stabilize the pressure in the pipeline 5 and reduce the pressure of the DC motor 2. loss, increase the service life, the signal is displayed on the display panel 71 of the controller 7 at the same time.

In this embodiment, the pre-filter device 1 includes a first pre-filter 11, a second pre-filter 12 and a third pre-filter 13, the first pre-filter 11 is mainly used to filter common impurities in water, The second pre-filter 12 is mainly to filter heavy metal substances, the third pre-filter 13 is mainly to filter bacteria in water, the first pre-filter 11, the second pre-filter 12 and the third pre-filter 13 Through pipeline 5 in series into 3 filters, and further in front of the first pre-filter 11 or in the pipeline 5 between the first pre-filter 11 and the second pre-filter 12 is provided with a low pressure switch 14, the low pressure switch 14 through It is electrically connected to the controller 7.

Please refer again to Fig. 2, when the filtrated water treated by the front filter device 1 is delivered to the reverse osmosis filter 3 through the pipeline 5 so that the filtrated water is converted into clean water, since the reverse osmosis filter 3 is used to produce clean water Higher pressure is required, so a DC motor 2 needs to be added to the pipeline 5 between the pre-filter device 1 and the reverse osmosis filter 3 to provide sufficient pressure to enable the reverse osmosis filter 3 to perform the water purification function. Due to the current market The RO membrane in the upper reverse osmosis filter 3 is a semi-permeable membrane, which is a porous material. Water can only flow in from one side without backflow, and its pore size is just enough to pass water molecules, so it is larger than water molecules. Molecules such as heavy metals, phenols, and fluorescent agents cannot pass through, nor can bacteria, coliform bacteria, and viruses pass through. However, due to the small pore size, it is easy to cause blockage compared to suspended particles in water. When the RO membrane blockage problem occurs, the sensor 6 located between the DC motor 2 and the reverse osmosis filter 3 receives the signal of the pressure increase in the pipeline 5 and sends the signal to It is sent to the controller 7, and the rotation speed of the DC motor 2 is reduced by the control of the controller 7 to stably provide an appropriate pressure for the reverse osmosis filter 3 to produce water.

Please refer to Figures 1 and 2 again. When the DC motor 2 is pressurized, the water pressure pushes the water molecules to pass through the reverse osmosis filter 3 to separate the water from the impurities and leave the impurities. Part of the incoming water is treated to be pure. Turned into high-quality clean water, the clean water will flow from the water purification pipe 31 of the reverse osmosis filter 3 to the pipeline 5, and then be transported to the water outlet device 4 by the pipeline 5 for drinking by the user, while the rest of the water will be discharged from the waste water pipe 32 discharge, in this embodiment, the waste water pipe 32 will be provided with a waste water ratio controller 321 to control the ratio of waste water to clean water.

When the user opens the faucet 41 to obtain the required clean water, on the other hand, the water storage tank 42 can also be used to store the clean water to provide users with sufficient water in a timely manner, and the high pressure switch 43 detects that the clean water is full of pressure in the pipeline 5 When increasing, the signal is sent to the controller 7 to stop the DC motor 2, so as to avoid the waste of electric power.

From the description of the above embodiments, it can be seen that the main effect of this invention is that the following benefits can be achieved through the composition design of the sensor 6 and the controller 7: since the DC motor 2 of this invention is connected through the controller 7, and the sensor 6 It is installed on the pipeline 5 between the DC motor 2 and the reverse osmosis filter 3, so the pressure value of the pipeline 5 can be detected by the sensor 6 during the continuous output of the DC motor 2, and then the pressure of the DC motor 2 When the output value can be used with the reverse osmosis filter 3 to produce clean water, the rotation speed of the DC motor 2 can be changed by the adjustment of the controller 7, and then a constant pressure value can be adjusted so that the reverse osmosis filter 3 can continuously generate Water purification; on the other hand, control the reverse osmosis filter 3 pipeline to avoid excessive pressure, so the DC motor 2 can be in a stable pressure output range, preventing the loss of life of the DC motor 2 due to high pressure output.
