Description

Technical Field

[0001] The utility model relates to the field of small commercial water purifiers, and in particular to an intelligent self-flushing reverse osmosis water purifier capable of performing pure water flushing. Background Art

[0002] In order to ensure the stable and effective operation of the reverse osmosis system, the flushing of traditional household and commercial small reverse osmosis water purifiers is generally done by quickly flushing the R0 membrane surface with tap water before or after water production, so as to quickly flush and replace the concentrated water with high salt content on the membrane surface with tap water to avoid salt deposition on the R0 membrane surface. Failure to perform tap water flushing will cause the machine to produce water at a reduced speed, reduce the water production rate, increase the machine load, and increase the failure rate. In the process of implementing the above technology, most machines rely on computer boards to control the operation of the entire machine. At the appropriate time, the flushing time and frequency are set, and tap water is used to flush and protect the membrane surface.

[0003] A Chinese patent discloses a reverse osmosis water purifier (authorization announcement number CN 203159288 U). The patented technology can be easily installed and used in households. The isolation device can be moved up and down. Regardless of the ratio of pure water to domestic water, the pressure generated on each pipeline in the water purification system is the same, which does not affect the normal operation of the water purification system. However, the water purifier requires an electronic control panel for control, and the hardware cost of the entire system is high.

[0004] Therefore, those skilled in the art provide an intelligent self-flushing reverse osmosis water purifier that can perform pure water flushing to solve the problems raised in the above background technology. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides an intelligent self-flushing reverse osmosis water purifier that can perform pure water flushing, which consists of a pretreatment purification unit, a water inlet solenoid valve, a booster pump, an R0 membrane filter element, a flushing solenoid valve, a control module one, a first one-way valve, a high-pressure switch, a membrane washing solenoid valve, a control module two, a second one-way valve, a pressure barrel, post-charcoal, and a water purification faucet. The pretreatment purification unit is mainly composed of a PP cotton + carbon filter combination, and the power supply V-pole is connected in series with the high-pressure switch to the negative pole of the water inlet solenoid valve and the booster pump.

[0006] Preferably: the positive pole of the water inlet solenoid valve and the positive pole of the booster pump are connected in parallel to the positive pole + of the 24V power supply. The regular water inlet solenoid valve does not distinguish between positive and negative poles and can be connected to any end. The signal lines of the control module 1 of the flushing solenoid valve and the control module 2 of the membrane washing solenoid valve are connected to the negative end of the high-voltage switch (when the connection is correct, there will be an indicator light on the module, otherwise the light will be off). The flushing solenoid valve and the membrane washing solenoid valve are quickly connected to the independent control module 1 and control module 2 respectively, and the whole machine is no longer controlled by circuit.

[0007] Preferably: the signal of the control module 1 and the control module 2 is connected in series on the high-pressure switch, and the input signal is obtained by opening and closing it, so as to execute different pure water flushing methods. The signal line of the control module 1 and the flushing solenoid valve module may also be connected to the negative pole of the water inlet solenoid valve or the booster pump, and then connected in series to the negative pole of the high-pressure switch to achieve the same effect. The high-pressure switch is preferably a switch with a stable pressure difference of 1.0 to 1.5 kg. The reverse osmosis water purifier is suitable for a water purifier with a pressure barrel, which can be a small gallon machine or a 400 to 800 gallon machine, but it must have a pressure barrel.

[0008] Technical effects and advantages of the utility model:

[0009] 1. The whole machine configured with this technology in this utility model abandons the traditional electric control panel control method, and realizes the effect of pure water flushing by using a special module to quickly connect the solenoid valve.

According to the required water circuit and circuit connection method, it can realize flexible and changeable pure water automatic flushing mode. It is more flexible and powerful than the traditional self-flushing machine, and can efficiently and simply realize the special function of pure water membrane washing.

[0010] 2. The water purifier does not require circuit board control, and can realize automatic flushing and combined flushing with tap water and pure water. The flushing method can be adjusted as needed, which is flexible and changeable. It is a pure water self-flushing reverse osmosis system with simple electronic control and efficient and reliable operation. It has no electronic control board, the system is simple and reliable, the hardware cost of the whole system is greatly reduced, and the failure rate is low. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0016] Example 1

[0017] See also Figures 1 to 3 In this embodiment, an intelligent self-flushing reverse osmosis water purifier capable of performing pure water flushing is provided, which is composed of a pretreatment purification unit 1, a water inlet solenoid valve 2, a booster pump 3, an R0 membrane filter element 4, a flushing solenoid valve 5, a control module 1 6, a first one-way valve 7, a high-pressure switch 8, a membrane washing solenoid valve 9, a control module 2 10, a second one-way valve 11, a pressure barrel 12, a post-charcoal 13, and a water purification faucet 14. The pretreatment purification unit 1 is mainly composed of a PP cotton + charcoal filter combination, and the power supply 24V- is connected in series with the high-pressure switch 8 to the negative pole of the water inlet solenoid valve 2 and the booster pump 3, and the positive pole of the water inlet solenoid valve 2 and the positive pole of the booster pump 3 are connected in parallel to the positive pole of 24V+. The water inlet solenoid valve 2 is usually not divided into positive and negative poles and can be connected to any end;

[0018] The signal lines of the control module 1 6 of the flushing solenoid valve 5 and the control module 2 10 of the membrane washing solenoid valve 9 are connected to the negative terminal of the high-voltage switch 8 (if the connection is correct, there will be an indicator light on the module, otherwise the light will be off);

[0019] Furthermore, the flushing solenoid valve 5 and the membrane washing solenoid valve 9 are quickly connected to the independent control module 6 and the control module 2 10 respectively, and the whole machine is no longer controlled by circuits.

[0020] Furthermore, the control module 1 6 and the control module 2 10 are connected in series to the high-voltage switch 8, and the input signal is obtained by opening and closing the switch, thereby executing different pure water flushing modes;

[0021] Possibly, the signal line of the control module 1 6 and the flushing solenoid valve module 10 may also be connected to the negative pole of the water inlet solenoid valve 2 or the booster pump 3, and then connected in series to the negative pole of the high-pressure switch 8, which can achieve the same effect;

[0022] The high-pressure switch 8 is preferably a switch with a stable pressure difference of 1.0 to 1.5 kg;

[0023] The whole machine configured with this technology abandons the traditional electric control panel control method, and realizes the effect of pure water flushing by using a special module to quickly connect the solenoid valve. The machine plugs the pure water membrane washing module on the pure water membrane washing solenoid valve 9, and plugs the automatic flushing module on the traditional combined flushing valve. According to the required water circuit and circuit connection method, flexible and changeable pure water automatic flushing mode can be realized;

[0024] The water purifier does not require circuit board control, and can achieve automatic flushing and combined flushing with tap water and pure water. The flushing method can be adjusted according to needs, which is flexible and changeable. It is a pure water self-flushing reverse osmosis system with simple electronic control, efficient and reliable operation;

[0025] For example, when the machine is powered on, it can be flushed with tap water for 18 seconds, the flushing combination solenoid valve is opened for 18 seconds (the duration can be adjusted), and the membrane washing solenoid valve 9 is set to not work;

[0026] For another example, when the machine is full of water, the pure water flushing can be set for 12 seconds, the membrane washing solenoid valve 9 is opened for 12 seconds, and the flushing combination solenoid valve is opened for 12 seconds;

[0027] For example, when the machine is full of pure water, it can be set to flush for 3 seconds and close for 3 seconds (the membrane washing solenoid valve 9 is opened for 3 seconds and closed for 3 seconds, and the flushing solenoid valve is opened for 3 seconds and closed for 3 seconds), and the pulse cycle flushes 3 to 5 times, etc., which changes the flushing method and frequency and improves the flushing effect;

[0028] Of course, it can also be set as needed to flush with full pure water for 120 seconds, and the flushing combination valve does not work (slowly replace the high-salt concentrated water in the membrane layer through the wastewater ratio), etc. The flushing method can be flexibly combined as needed and realized by module control;

[0029] The reverse osmosis water purifier is suitable for a water purifier with a pressure barrel type, which can be a small gallon machine or a 400-800 gallon machine, but it must have a pressure barrel 12.

[0030] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
