Description

Technical Field

[0001] This utility model relates to a car beverage brewing water supply system, belonging to the field of water supply system technology. Background Technology

[0002] In recent years, with the steady development of my country's economy and the steady improvement of residents' living standards, the number of private cars has continued to rise. Due to its convenience, the car has become an indispensable means of transportation for people's daily lives. Whether it's commuting between home and workplace, frequent business trips, or road trips with family and friends during holidays, the car plays a crucial role. As people spend more time in their cars, their demands for the variety and quality of beverages served in their vehicles are also becoming increasingly diverse.

[0003] However, some existing beverage brewing systems on the market have problems and cannot meet the actual needs of in-car beverage brewing. After brewing, these systems often leave a certain amount of liquid residue in the water system that cannot be cleaned. This residue can easily breed bacteria during prolonged parking, affecting not only the hygiene and safety of the beverages but also potentially posing a health threat to the user. Especially in winter, when cars are parked outdoors, the residual liquid in the water system is prone to freezing. The expansion of the frozen liquid can damage the water system and related components, affecting the normal operation of the entire beverage brewing system, shortening its lifespan, and increasing operating costs.

[0004] Therefore, there is a need for a car beverage brewing and water supply system that can solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a new technical solution to improve or solve the technical problems existing in the prior art as described above.

[0006] The technical solution provided by this utility model is as follows: A car beverage brewing water supply system includes a control system, and further includes a water storage device, a first solenoid valve, a water pump, a heating device, a second solenoid valve, and a flow meter. The water storage device, pipeline level sensor, first solenoid valve, water pump, heating device, second solenoid valve, and flow meter are connected in series through pipelines. The pipeline level sensor is installed on the pipeline between the water storage device and the first solenoid valve. The second solenoid valve is also connected to the water storage device through a return water pipe. The first solenoid valve is also provided with an air inlet. The control system is electrically / signally connected to the pipeline level sensor, first solenoid valve, water pump, heating device, second solenoid valve, and flow meter.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, it also includes an air pump, which is connected to the air inlet of the first solenoid valve. The control system is electrically / signally connected to the air pump to control the start and stop of the air pump, so as to deliver gas into the pipeline through the air pump and assist in the discharge of liquid in the pipeline.

[0009] The beneficial effect of adopting the above-mentioned further solution is that when it is necessary to clean the pipeline or drain residual liquid, the air pump delivers gas into the pipeline, which can accelerate the drainage of liquid in the pipeline, avoid the growth of bacteria from liquid residue, and improve the hygiene and reliability of the system.

[0010] Furthermore, the return water pipe is equipped with a one-way valve, the one-way valve being directed from the second solenoid valve to the water storage device, to prevent water in the water storage device from flowing back to the second solenoid valve.

[0011] The advantage of adopting the above-mentioned further solution is that it prevents water in the water storage device from flowing back to the second solenoid valve and subsequent pipelines, thus avoiding affecting the normal operation of the system.

[0012] Furthermore, the heating device is equipped with a temperature sensor, which is electrically / signally connected to the control system. The control system controls the heating power of the heating device based on the temperature information fed back by the temperature sensor, so as to heat the water to the set temperature.

[0013] The beneficial effect of adopting the above-mentioned further solution is that the control system can accurately control the heating power of the heating device based on the temperature information fed back by the temperature sensor, heat the water to the set temperature, meet the water temperature requirements of different beverage brewing, and improve the quality of beverage brewing.

[0014] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects: The water supply system of this utility model can not only provide users with a stable water flow for beverage brewing according to actual needs, but also, after the beverage brewing is completed, the control system opens the first solenoid valve to connect with the air, and simultaneously opens the second solenoid valve to connect with the water storage device, which can promptly remove residual water in the pipeline. Therefore, this utility model can effectively prevent the growth of bacteria due to residual water in the pipeline, and in cold weather conditions, it will not cause pipeline damage due to freezing of residual water.

[0020] The principles and features of this utility model are described below with reference to examples. The examples are only used to explain this utility model and are not intended to limit the scope of this utility model.

[0021] like Figure 1 As shown, a car beverage brewing water supply system includes a control system 10, a water storage device 1, a pipeline level sensor 2, a first solenoid valve 3, a water pump 4, a heating device 5, a second solenoid valve 6, and a flow meter 7. The water storage device 1, the first solenoid valve 3, the water pump 4, the heating device 5, the second solenoid valve 6, and the flow meter 7 are connected in series via pipelines. The pipeline level sensor 2 is installed on the pipeline between the water storage device 1 and the first solenoid valve 3. The second solenoid valve 6 is also connected to the water storage device 1 via a return water pipe. The first solenoid valve 3 is also provided with an air inlet. The control system 10 is electrically / signally connected to the pipeline level sensor 2, the first solenoid valve 3, the water pump 4, the heating device 5, the second solenoid valve 6, and the flow meter 7.

[0022] More specifically, the water storage device 1 is used to store the water needed for brewing beverages; the pipeline level sensor 2 is used to detect the liquid level in the pipeline; the heating device 5 is used to heat the water in the pipeline; the first solenoid valve 3 is used to control the flow of water and air in the pipeline, and can open or close the corresponding channel according to the instructions of the control system 10 to allow or prevent the passage of water and air in the pipeline; the second solenoid valve 6 is used to control whether the heated water flows out and to control the flow of water back through the return pipe; the flow meter 7 is used to measure the flow rate of the outgoing water.

[0023] In this embodiment of the invention, the pipeline level sensor 2 is installed on the pipeline between the water storage device 1 and the first solenoid valve 3. When water is needed, the water pump 4 is activated, and the pipeline level sensor 2 can detect whether there is water flow in the pipe, thereby detecting whether there is a water shortage in the water storage device 1. When a water shortage is detected, it can remind the user to add water. Compared to placing the level sensor inside the water storage device 1, when the water storage device 1 needs to be replaced, there is no need to disassemble or reinstall the level sensor; simply remove the water storage device 1 from the water tank and replace it with a new one. The pipeline level sensor 2 can be an existing level sensor, such as the widely used capacitive level sensor. The capacitive level sensor uses the principle that changes in capacitance caused by changes in water level to detect the water level in the pipeline. However, capacitive level sensors can only be applied to water tanks or pipes made of non-metallic materials, because substances contained in metallic materials can also cause changes in capacitance, which may lead to false readings.

[0024] The car beverage brewing and water supply system also includes an air pump 8, which is connected to the air inlet of the first solenoid valve 3. The control system 10 is electrically / signally connected to the air pump 8 to control its start and stop, thereby delivering gas into the pipeline to assist in the drainage of liquid within the pipeline. When it is necessary to clean the pipeline or drain residual liquid, the air pump 8 delivers gas into the pipeline, which can accelerate the drainage of liquid, prevent the growth of bacteria from residual liquid, and improve the hygiene and reliability of the system.

[0025] The return water pipe is equipped with a one-way valve 9. The one-way valve 9 is directed from the second solenoid valve 6 to the water storage device 1. It is used to prevent water in the water storage device 1 from flowing back to the second solenoid valve 6. The one-way valve 9 can prevent water in the water storage device 1 from flowing back to the second solenoid valve 6 and subsequent pipelines, so as to avoid affecting the normal operation of the system.

[0026] The heating device 5 is equipped with a temperature sensor, which is electrically / signally connected to the control system 10. The control system 10 controls the heating power of the heating device 5 based on the temperature information fed back by the temperature sensor, thereby heating the water to the set temperature. The control system 10 can precisely control the heating power of the heating device 5 based on the temperature information fed back by the temperature sensor, heating the water to the set temperature to meet the water temperature requirements for brewing different beverages and improve the quality of beverage brewing.

[0027] The working method of this utility model's car beverage brewing and water supply system is as follows:

[0028] After the user issues a beverage brewing command, the control system 10 starts operating. First, the control system 10 controls the first solenoid valve 3 to open, allowing water from the water storage device 1 to enter the pipeline, and at the same time starts the water pump 4 to deliver the water to the heating device 5.

[0029] When water flows through the heating device 5, it is heated. During this process, a temperature sensor monitors the water temperature in real time and feeds the data back to the control system 10. If the outlet water temperature is detected to be below the preset requirement, the control system 10 will control the second solenoid valve 6 to switch to the state of being connected to the water storage device 1. At this time, the hot water in the heating device 5 will not flow to the outlet, but will temporarily flow back into the water storage device 1 to wait for the water temperature to rise further, thus preventing the outflow of hot water that is not at the required temperature and ensuring the taste and quality of the beverage.

[0030] The heating device 5 operates continuously. When the water temperature rises to meet the outlet requirements, the control system 10 controls the second solenoid valve 6 to quickly switch the water path to the outlet. At this time, hot water flows out from the outlet after being measured by the flow meter 7, allowing the user to obtain hot water at the required temperature for brewing various beverages. Simultaneously, the flow meter 7 monitors the water flow rate in real time and feeds the data back to the control system 10, enabling the control system 10 to precisely control the water supply flow rate.

[0031] After brewing, the control system 10 performs the following operations: first, it switches the first solenoid valve 3 to connect with air, and then switches the second solenoid valve 6 to connect with the water storage device 1. If the system is equipped with an air pump 8, the air pump 8 will start and supply gas into the pipeline. When the first solenoid valve 3 is switched to connect with the water pump 4, under the push of the gas supplied by the air pump 8, the residual water in the system will be discharged sequentially along the water pump 4, the heating device 5, the second solenoid valve 6, and the one-way valve 9 on the return water pipe to the water storage device 1. When the first solenoid valve 3 is switched to connect with the water storage device 1, the water remaining in the pipeline between the water storage device 1 and the first solenoid valve 3 can be discharged into the water storage device 1. This design can prevent residual water from breeding bacteria or damaging the pipeline due to water freezing in cold weather.

[0032] This utility model's water supply system not only provides users with a stable water flow for beverage brewing according to actual needs, but also, after the beverage is brewed, the control system 10 activates the first solenoid valve 3 to connect with air, and simultaneously activates the second solenoid valve 6 to connect with the water storage device 1, thus promptly clearing residual water from the pipeline. Therefore, this utility model effectively prevents bacteria growth from residual water, and in cold weather conditions, it prevents pipeline damage caused by freezing of residual water.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
