By arranging the plug 122 on the second pipeline 120, the opening at the upper end of the second pipeline 120 does not need to be specially sealed in the manufacturing process of the shell 100, the manufacturing process of the shell 100 is simplified, and a user can connect the opening at the upper end of the second pipeline 120 with other pipeline systems or other detection components according to actual needs, so that the functions of the filter are more diversified.

According to the utility model discloses the method of adopting intelligent filter to detect hourglass water of second aspect embodiment, intelligent filter is including casing 100, pressure sensor 300 and control module group, wherein is equipped with the water inlet 111 and the delivery port 112 that communicate each other on the casing 100, and pressure sensor 300 sets up at casing 100 inboardly, and control module group is connected with pressure sensor 300 electricity.

The method for detecting water leakage comprises the following steps: cutting off the connection of the water inlet 111 and the external water supply pipeline; closing the water outlet end of the user pipeline system; the pressure sensor 300 detects the pressure change of the pipeline system within the detection time in the control module, and the control module judges whether water leakage occurs according to the pressure change of the pipeline system.

By the detection method, a user can judge whether water leakage occurs by detecting the pressure change in the pipeline system. Specifically, the pressure sensor 300 detects water leakage on the principle that when the connection between the water inlet and the external water supply line is cut off and the water outlet end of the user's piping system is closed, if water leakage occurs, the liquid in the piping system will leak out continuously, the liquid pressure in the piping system will decrease continuously, and if water leakage does not occur, the liquid pressure in the filter should be constant. The first valve module 500 is normally closed, and when a user wants to detect whether water leaks from the pipeline, it is necessary to cut off the connection of the water inlet 111 to the external water supply line and to close the water outlet end of the user pipe system, then the control module controls the pressure sensor 300 to detect the pressure of the pipeline system according to the built-in detection time, specifically, the pressure sensor 300 firstly detects the pressure of the pipeline system once and feeds back the detection result to the control module, then the pressure of the pipeline system is detected again after the set detection time, the detection result is fed back to the control module again, the control module calculates the pressure difference according to the results of the two detections, and judges whether water leakage occurs according to the pressure difference, if the pressure difference exceeds the set range, the water leakage is judged to occur, and if the pressure difference does not exceed the set range, the water leakage is judged not to occur. Besides the detection time in the control module, the user can also set the detection time by himself through the control module.

According to the utility model discloses the method of adopting intelligent filter to detect hourglass water of second aspect embodiment, intelligent filter is still including second valve module 600, and second valve module 600 sets up on water inlet 111, and second valve module 600 is connected with the control module electricity.

The step of "cutting off the connection of the water inlet 111 to the external water supply line" includes: a detection period is set in the control module, and the control module controls the second valve module 600 to close every time a detection period passes.

By the detection method, when a user goes out for a long time, the filter can periodically detect whether the pipeline system leaks water according to an internal detection period. When leakage occurs in the pipeline system and the water inlet 111 is communicated with an external water supply pipeline, and the water outlet end of the user pipeline system is closed, liquid can be continuously supplemented from the water inlet 111 to maintain the pressure of the pipeline system, the results of two times of detection by the pressure sensor 300 are not changed greatly, and whether the pipeline system leaks water or not is difficult to judge; when there is no leakage in the pipe system and the water outlet end of the pipe system is opened by a user, and the water inlet 111 is not communicated with the external water supply pipeline, the liquid is discharged from the water outlet 112, and the difference between the two detection results of the pressure sensor 300 is large, which may misjudge that the water leakage occurs in the pipe system. Therefore, when a user wants to detect whether the water leakage occurs in the pipe system, the connection between the water inlet 111 and the external water supply pipeline must be cut off and the water outlet end of the user pipe system must be closed, so as to obtain an accurate detection result. When a user goes out for a long time, the user generally checks whether the water outlet end of the user pipeline system is closed, but the connection between the water inlet 111 and an external water supply pipeline is not cut off. At this time, by providing a second valve module 600 at the water inlet 111, the filter can periodically detect whether water leakage occurs in the pipe system under the control of the control module even if the user goes out for a long time. Specifically, be equipped with the detection cycle in the control module group, under the state that delivery port 112 is closed, every other detection cycle, the control module group all can control second valve module 600 and close, then control pressure sensor 300 once detects the interior liquid pressure of pipe-line system, pressure sensor 300 detects and can feed back the testing result to the control module group after accomplishing, and detect the interior liquid pressure of pipe-line system once more and send the testing result for the control module group once more after the detection time of process settlement, the control module group can calculate the pressure differential and judge whether to take place to leak according to twice testing result. If water leakage occurs in the pipeline system, the control module can display the information of water leakage of the pipeline system and keep the second valve module 600 closed; if no water leakage occurs in the pipe system, the control module displays a message "no water leakage occurs in the pipe system" and opens the second valve module 600. Besides the detection period arranged in the control module, the user can also set the detection period by himself through the control module.
