Description

Technical Field

[0001] The utility model relates to a water purifier quality testing device, in particular to a water purifier tap life testing device. Background Art

[0002] The faucet is a frequently used switch device on the water purifier. The faucet used in the water purifier includes single-handle faucets and double-handle faucets; some are powered and some are not. If the faucet valve core is not tightly sealed, water leakage will occur during use, causing losses to users. Therefore, the life test of the faucet is a more important part of the quality inspection of water purifier equipment. However, the conventional faucet life test method is to manually open and close the faucet handle tens of thousands of times. This testing process is not only time-consuming and labor-intensive, but also extremely inefficient.

[0003] In response to the above problems, the test device disclosed in the Chinese invention application "Testing Device and Faucet Rotation Life Test Method" with patent application number CN202311002461.8 (published as CN116773181A) drives the faucet to swing within a preset angle through a driving motor and a transmission rod. Without manual intervention, the rotation life of the two rotating parts of the faucet can be automatically tested, thereby improving the test efficiency. However, the test device can only perform life tests on single-handle faucets and cannot simulate the environment in which the faucet is used at home. Therefore, there is a need for a faucet life test device that can test multiple types of faucets and simulate a home use environment. Utility Model Content

[0021] like Figure 1-2 As shown, the water faucet life test device of the water purifier of this embodiment includes a body 1, which is divided into a test area 2 and an electrical area 3 to achieve water-electricity separation and prevent water from entering the electrical components. The test area 2 includes a water tank 21 and at least one fixing seat 22 for fixing the faucet to be tested. The water tank 21 is arranged at the bottom of the test area 2, and the water tank 21 has a water inlet 211, an overflow port 212 and a drain port 213; the fixing seat 22 is arranged above the water tank 21, and the body 1 is provided with a water supply port 23, and the water tank 21, the water supply port 23 and the fixing seat 22 are in fluid communication. The fixing seat 22 is provided with a flow sensor for testing the water inlet flow of the faucet to be tested, so as to test the water inlet flow of the faucet to be tested. Each fixing seat 22 corresponds to two driving mechanisms, which are arranged on both sides of the fixing seat 22, and a connecting piece is arranged between the driving mechanism and the fixing seat 22 to connect the driving mechanism and the handle of the faucet to be tested, and the driving mechanism can drive the faucet to be tested to open or close. When testing a single-handle faucet, the faucet to be tested is fixed to the fixing seat 22, and the handle of the faucet to be tested is connected to the driving mechanism on one side of the fixing seat 22 by a connecting piece. The faucet to be tested is driven to open and close by the driving mechanism to simulate manual switching of the faucet to be tested; when testing a double-handle faucet, the faucet to be tested is fixed to the fixing seat 22, and the handles on both sides of the faucet to be tested are connected to the driving mechanisms on both sides of the fixing seat 22 by a connecting piece. The handles on both sides of the faucet to be tested are driven to open and close by two driving mechanisms to simulate manual switching of the faucet to be tested.

[0022] Specifically, the driving mechanism includes a cylinder 41 and a bracket 42 for mounting the cylinder 41. The bracket 42 is provided with a connection port 43, and the connection port 43 is connected to a compressed air device. The compressed air device provides power to the cylinder 41 to make the cylinder 41 do telescopic movement. The cylinder 41 drives the faucet to be tested to open or close to simulate manual opening or closing of the faucet to be tested: when the cylinder 41 is extended, the handle of the faucet to be tested is driven to open; when the cylinder 41 is retracted, the handle of the faucet to be tested is driven to close. The cylinder 41 and the bracket 42 are connected by a bearing 44, and the cylinder 41 can move up and down relative to the bearing 44 to ensure that the running direction of the cylinder 41 is consistent with the handle of the faucet to be tested.

The water purification mechanism 32 is arranged between the water tank 21 and the water supply port 23 to filter the test water flowing from the water tank 21 to the water supply port 23. The water purification mechanism 32 is provided with a first pressure-stabilizing pump 321, a composite filter element 322, a second pressure-stabilizing pump 323 and a pressure-stabilizing tank 324 in sequence in the direction of the fluid. The pressure-stabilizing tank 324 is provided with a ball valve (not shown in the figure). The first pressure-stabilizing pump 321 provides power for the water in the water tank 21 to enter the composite filter element 322. After being purified by the composite filter element 322, the water enters the water supply port 23 through the second pressure-stabilizing pump 323 and the pressure-stabilizing tank 324. The ball valve can adjust the water flow rate of the pressure-stabilizing tank 324 to match the flow rate of the faucet to be tested. The main control board 31 includes a display screen 311 and a buzzer 312. The display screen 311 is used to display the on-off time of the faucet to be tested, the flow rate of the faucet to be tested, the indicator light 314 of the faucet to be tested and other information, and the buzzer 312 is used for water shortage alarm.
