Description

Technical Field

[0001] The utility model relates to the technical field of water purifiers, in particular to a composite water purifier supply device for preventing sewage backflow. Background Art

[0002] A water purifier, also known as a water purifier or water filter, is a water treatment device that deeply filters and purifies water according to specific usage requirements. It effectively removes rust, sand, and colloids from water, and absorbs residual chlorine, odor, discoloration, pesticides, and other chemicals. It also effectively removes bacteria, impurities, toxins, and heavy metals from water.

[0003] Among them, patent number CN204841161U in the prior art discloses a water purifier, which is achieved by connecting a compressed air pipe and a water inlet pipe to the upper end of a water storage tank; the water storage tank is connected to a filtering device through a water storage pipe, and the pipe mouth of the water storage pipe extends to the lower end of the water storage tank. This technical means realizes that under the action of compressed air, water passes through a biological cotton tank, a quartz sand tank and an activated carbon tank in sequence and flows out from the discharge port. In this process, the water is subjected to pressure from the high-pressure air, thereby increasing the water output, so that it can provide sufficient water without being restricted by the water flow.

[0004] However, when the above-mentioned water purifier is purifying water, if the drain outlet is blocked and the water pressure changes in the middle of the sewage discharge, some sewage will reversely enter or penetrate into the filter element, causing some sewage to be discharged along with the purified water outlet, affecting the quality of the purified water. In addition, the existing water purifier needs to suspend work when cleaning the filter element, resulting in a decrease in the working efficiency of the water purifier; therefore, it does not meet the existing needs. In this regard, we propose a composite water purification supply device that avoids sewage backflow. Utility Model Content

[0005] The purpose of the present utility model is to provide a composite water purification device that prevents sewage backflow, so as to solve the problem proposed in the above-mentioned background technology that when the above-mentioned water purifier is purifying water, if the water outlet is blocked and the water pressure changes in the middle of the sewage discharge, some sewage will reversely enter or penetrate into the filter element, causing part of the sewage to be discharged along with the purified water outlet, affecting the quality of the purified water, and the existing water purifier needs to suspend work when cleaning the filter element, resulting in a decrease in the working efficiency of the water purifier.

[0023] Furthermore, the water pump 5 is connected to the clean water tank 4 through a water pipe A, and a water pipe B is installed at the other end of the water pump 5. The clean water tank 4 is connected to the water storage tank 2 through a connecting pipe. An external water pipe can be connected through the water pipe B to discharge the water to be filtered into the clean water tank 4 through the water pipe A, and the purified water is stored in the water storage tank 2 through the connecting pipe.

[0024] The water inlet chamber 7 is connected to the filter chamber 3 through the diverter chamber A8, and a solenoid valve A is installed on the inside of the diverter chamber A8. The filter chamber 3 is connected to the water outlet chamber 11 through the diverter chamber B10, and a solenoid valve B is installed on the inside of the diverter chamber B10. The water entering the purified water tank 4 first enters the water inlet chamber 7, and then is diverted through the diverter chamber A8. The water purified by the filter elements 9 on both sides passes through the diverter chamber B10 and is gathered in the water outlet chamber 11.

[0025] An electromagnetic valve C is installed on the inner side of the cleaning pipe 6. The filter element 9 consists of a sand filter layer, a sponge filter layer, a water molecule membrane filter layer, an activated carbon adsorption layer and an ultrafiltration membrane filter layer from top to bottom. The sand filter layer can first filter out larger impurities, and then the ultrafiltration membrane filter can filter out various bacteria, viruses and other substances to ensure that the water can meet drinking standards.

By connecting the cleaning pipe 6 to an external water pipe, the filter element 9 can be backwashed, while the filter element 9 on the other side continues to filter, without pausing work and without affecting work efficiency. In addition, by providing an anti-backflow mechanism 13, when sewage is discharged, the pressure of the water flow pushes the movable plate 1303 and the block 1305 backward, and sewage and impurities can pass through. The sewage is discharged through the gap between the through groove 1306 and the block 1305. When the sewage is drained, there is no water pressure. The movable plate 1303 and the block 1305 move forward under the action of the spring 1302. The block 1305 is stuck in the inner side of the through groove 1306 to block the sewage pipe 12, thereby preventing part of the sewage from reversely entering or penetrating into the filter element 9. The utility model is provided with two filter elements 9, which can be cleaned separately without suspending work and will not affect work efficiency. In addition, the anti-backflow mechanism 13 can prevent part of the sewage from reversely entering the filter element 9.
