Automatic functional test device of coffee maker

Abstract

The invention relates to an automatic functional test device of a coffee maker. The automatic functional test device comprises a water supply mechanism, a coffee bag prosthesis supply mechanism, a needle valve, a water outlet valve, a flow meter, a temperature sensor, a pressure sensor and a control system. The water supply mechanism is used for filling water into the coffee maker to be tested and comprises a water tank and a port connected with the water tank. The coffee bag prosthesis supply mechanism is used for placing a coffee bag prosthesis into the coffee maker to be tested. On a test water path of the coffee maker to be tested, the needle valve is located on the downstream of the coffee bag prosthesis, the water outlet valve is located on the downstream of the needle valve, the flow meter is located on the upstream of the coffee maker to be tested and arranged between the water tank and the port, the temperature sensor is located on the coffee bag prosthesis, and the pressure sensor is located between the coffee bag prosthesis and the needle valve. The control system controls the water supply mechanism and the coffee bag prosthesis supply mechanism to act, receives signals emitted by the flow meter, the temperature sensor and the pressure sensor and outputs the signals after processing the signals. The test device is high in test efficiency, low in labor intensity and capable of ensuring the quality of products which are massively produced.

Description

technical field [0001] The invention relates to a detection device, in particular to an automatic function test device for a coffee machine. Background technique [0002] During the production process of the coffee machine, it is necessary to test the functions of the coffee machine, such as: the maximum power at work, the output water flow, the temperature of the hot water output, the maximum pressure of the water pump, the pipeline pressure and other parameters. At present, most factory-produced coffee machines are tested manually, and only one or a few parameters can be tested at a time, and the parameter test can be completed after repeated several times. [0003] There are many shortcomings in the above-mentioned testing methods. First, manual operation cannot guarantee the quality of mass production. For example, untested products may flow out, measured parameters may be read incorrectly, and defective products may flow out as good products, etc.; , Manual testing is ...

Problems solved by technology

[0003] There are many shortcomings in the above-mentioned testing methods. First, manual operation cannot guarantee the quality of mass production. For example, untested products may flow out, measured parameters may be read incorrectly, and defective products may flow out as good products, etc.; Second, , Manual testing is inefficient and labor-intensive. Before the test, you need to put the water tank, plug in the power supply, put the coffee bag, press the button, etc. During the test, you need to check the power meter, flow meter, pressure gauge, etc. The test shows the current value, but the maximum temperature is required , maximum power, maximum pressure, etc. After the test is completed, it is necessary to record the parameters, judge whether it is qualified or not, remove the water tank, unplug the power supply, take out the coffee bag, etc.; third, the test period is long, and the manual operation is slow. The test time cannot be accurately grasped by manual operation; Fourth, the workload of manually recording test data is heavy, and it is easy to make mistakes, which is not conducive to future data query and analysis
