[0025] To make the objectives, features, and advantages of this application more readily apparent, the present application is further described below in conjunction with the accompanying drawings and specific embodiments. It is apparent that the embodiments described are only a portion of the embodiments of this application, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments in this application without inventive effort are also within the scope of protection of this application.

[0026] By analyzing the existing technology, the inventors found that in the existing faucet heavy metal precipitation detection, the common method is to manually inject the test immersion liquid into the sample to be tested for detection. The testing procedure for faucet metal precipitation is very complicated. Not only does it require introducing tap water into the faucet cavity, but it also requires repeated water changes and water extraction, and also requires considering the contact frequency, contact time and contact temperature of tap water in the faucet cavity.

[0027] Reference Figure 1 , showing a schematic diagram of the internal structure of an automatic extraction device for metal precipitates from faucets provided by the present application.

[0028] An automatic extraction device for metal precipitates from faucets, comprising a liquid storage tank 1, a bracket 2, a multi-way valve 3, a controller, and an extraction mechanism electrically connected to the controller;

[0029] The bracket 2 supports the liquid storage tank 1. The top of the liquid storage tank 1 is provided with a liquid inlet end, and the bottom of the liquid storage tank 1 is provided with a liquid outlet end. The liquid outlet end of the liquid storage tank 1 is connected to the liquid inlet end of the multi-way valve 3. The liquid outlet end of the multi-way valve 3 is connected to the liquid inlet end of the faucet to be tested. The liquid outlet end of the faucet to be tested is connected to the liquid inlet end of the extraction mechanism.

[0030] When the controller is turned on, the extraction mechanism extracts the liquid in the liquid storage tank 1 into the inside of the faucet to be tested.

[0031] In an embodiment of the present application, relative to the problem that the testing procedure for metal precipitates on faucets in the prior art is very complicated, the present application provides a solution for automatically controlling the injection and discharge of detection reagents in faucets, specifically: comprising a liquid storage tank 1, a bracket 2, a multi-way valve 3, a controller and an extraction mechanism electrically connected to the controller; the bracket 2 supports the liquid storage tank 1, the top of the liquid storage tank 1 is provided with a liquid inlet end, the bottom of the liquid storage tank 1 is provided with a liquid outlet end, the liquid outlet end of the liquid storage tank 1 is connected to the liquid inlet end of the multi-way valve 3, the liquid outlet end of the multi-way valve 3 is connected to the liquid inlet end of the faucet to be tested, and the liquid outlet end of the faucet to be tested is connected to the liquid inlet end of the extraction mechanism; when the controller is turned on, the extraction mechanism extracts the liquid in the liquid storage tank 1 into the inside of the faucet to be tested. The extraction mechanism and controller enable automatic injection of liquid from the liquid storage tank 1. Closing the extraction mechanism retains the test water sample within the faucet under test. The system's sophisticated design accurately simulates the process of drinking water flowing from the storage tank, through the drinking water pipeline, and then through faucets and other end-use kitchen and bathroom products for consumers under normal living conditions. The system can also simulate the prolonged retention of drinking water within a faucet when it's not in use, allowing for an assessment of the potential impact of faucet internal materials on drinking water safety.

[0032] Next, an automatic extraction device for metal precipitates from a faucet in this exemplary embodiment will be further described.

[0033] As an example, given that metal materials may contain harmful heavy metals, the water channel structure of this equipment avoids using metal water-passing materials to ensure that the test results are not affected by the heavy metal precipitation of the equipment itself, eliminating the risk of heavy metal precipitation.

[0034] In one embodiment of the present application, a temperature sensor 4 and a constant temperature heating mechanism 5 are provided in the liquid storage tank 1, and the temperature sensor 4 and the constant temperature heating mechanism 5 are electrically connected to the controller respectively;

[0035] When the controller is turned on, the constant temperature heating mechanism 5 heats the liquid in the liquid storage tank 1 at a constant temperature through the temperature sensor 4 .

[0036] It should be noted that the constant temperature heating mechanism 5 employed heats the liquid in the liquid storage tank 1 in a water bath format and precisely controls the temperature. The entire system boasts a sophisticated structural design, accurately simulating the process of drinking water in a normal living environment, from being heated in the water storage tank to flowing through the drinking water pipeline and then to being consumed by consumers through faucets and other end-use kitchen and bathroom products.

[0037] In a specific implementation, a waterproof or other heat-conducting medium is provided in the space between the outside of the liquid storage tank 1 and the bracket 2, and a heating tube and a temperature sensor 4 are installed at the bottom of the pot in the liquid storage tank 1 to achieve precise temperature control.

[0038] In one embodiment of the present application, the constant temperature heating mechanism 5 includes a stirring device, and the stirring device is electrically connected to the controller.

[0039] It should be noted that the liquid in the liquid storage tank 1 includes test reagents and regular drinking water. The controller controls the stirring device to stir the test reagents and regular drinking water so that the test reagents and regular drinking water are fully blended and the liquid temperature in each part of the liquid storage tank 1 is kept uniform.

[0040] In one embodiment of the present application, the stirring device includes a scale for measuring the height of the liquid in the liquid storage tank 1.

[0041] It should be noted that the scale can be used to clearly indicate the volume of liquid injected into the liquid storage tank 1 to avoid overdosage.

[0042] In one embodiment of the present application, the extraction mechanism includes a vacuum pump.

[0043] It should be noted that, through the extraction function of the vacuum pump, this device can automatically realize the injection of liquid in the liquid storage tank 1. When the water path of the test sample is filled with the test water sample and the vacuum pump is turned off, the test water sample will be retained inside the terminal device. After the preset retention time, the vacuum pump is started again to discharge the water path in the test sample and collect it for analysis. The vacuum pump automatically flows out the liquid in the faucet to be tested by extracting negative pressure, and the material of the vacuum pump itself does not directly contact the liquid to be tested, so it will not have an adverse effect on the test results. The entire system structure is exquisitely designed and can accurately simulate the process of drinking water in a normal living environment from the water tank to the drinking water pipeline, and then through the terminal kitchen and bathroom products such as faucets for consumers to drink. At the same time, the system can also simulate the drinking water staying inside the faucet for a long time when it is not in use, thereby evaluating the potential impact of the internal materials of the faucet on the hygiene and safety of drinking water.

[0044] In one embodiment of the present application, the multi-way valve 3 includes at least three channels;

[0045] One of the channels is the liquid inlet end of the multi-way valve 3, and the liquid inlet end of the multi-way valve 3 is connected to the liquid outlet end of the liquid storage tank 1, and the remaining channels are the liquid outlet ends of the multi-way valve 3;

[0046] The liquid outlet of one of the multi-way valves 3 is a waste liquid outlet, and the liquid outlets of the other multi-way valves 3 are connected to the liquid inlet of the faucet to be tested.

[0047] It should be noted that the liquid in the liquid storage tank 1 can be discharged as waste water from the waste liquid outlet after testing the taps after the rated batch. The liquid outlet of the remaining multi-way valve 3 is greater than or equal to 1, and multiple taps can be tested at the same time to improve testing efficiency.

[0048] In a specific implementation, referring to Figure 2 , is a top view of the multi-way valve 3, which has five liquid outlets, one of which is a waste liquid outlet, and the other four flange outlets are used to connect to the faucets to be tested.

[0049] In one embodiment of the present application, the top of the liquid storage tank 1 is further provided with an exhaust port for discharging water vapor generated during heating.

[0050] In one embodiment of the present application, the temperature sensor 4 is a PT100 temperature sensor. This sensor is an instrument that converts temperature variables into a transmittable standardized output signal. It is mainly used for measuring and controlling temperature parameters in industrial processes.

[0051] In one embodiment of the present application, frame casters are provided at the bottom of the bracket 2. The frame casters facilitate the movement of the equipment.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the embodiments of the present invention.
