Description

Technical Field

[0001] The utility model relates to the technical field of faucets, and more specifically, it relates to a new type of anti-scald faucet and heating system. Background Art

[0002] A faucet, also known as a water valve, is a switch used to control the inflow and outflow or the size of water flow, and it is widely used in many scenarios. For example, it is connected to the end of a water pipe to control the switch and the outflow size of tap water; for another example, it is connected to the water outlet end of a water heater to control the switch and the outflow size of hot water; for another example, it is connected to the discharge end of various beverage machines to control the switch and the outflow size of beverages, and so on.

[0003] When the above faucet structure is used in a device that can heat liquids such as a water heater (hereinafter referred to as a liquid heating device), it is usually installed at the liquid outlet end of the liquid heating device (the outflow of water, beverages, etc. are all collectively referred to as liquid outflow hereinafter). When the liquid in the liquid heating device is heated (especially by high temperature heating), the air in the liquid heating device will also be heated accordingly, and the pressure in the liquid heating device will gradually increase during the heating process. Once the faucet at the liquid outlet end is opened, the high-temperature liquid in the liquid heating device may be ejected under high pressure, thus scalding the human body.

[0004] To solve the above technical problems, those skilled in the art can easily think of directly reducing the pressure of the liquid heating device first. The specific direct reduction method is mainly to first discharge some of the gas inside the liquid heater through a pressure valve similar to a pressure cooker, so that the internal pressure reaches equilibrium with the external atmosphere, and then discharge the liquid in the liquid heating device through the faucet structure.

[0005] Although the above solution can solve the problem of high-temperature liquid spraying and scalding the human body, the above structure will add a special exhaust valve and is also inconvenient to use. During the operation process, it is necessary to first open the exhaust valve, and after the pressure in the liquid heating device drops, the faucet can be opened to discharge the corresponding liquid. Once an operation error occurs, such as directly opening the faucet, the situation of high-temperature liquid spraying will still occur.

[0006] Therefore, the above solution is not only complex in structure and operation (a separate exhaust valve is added, and it is necessary to exhaust first and then discharge the liquid), but also once an operation error occurs, the situation of high-temperature liquid spraying still cannot be avoided. Summary of the Utility Model

[0033] The following describes the preferred embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustration and explanation of the present utility model, and are not used to limit the present utility model. The orientation terms such as "upper" and "lower" involved herein are determined with respect to the perspective of the drawings, and are only for the convenience of description and should not be construed as a limitation of the technical solution. The "first, second,..." used herein are only for differentiating names and do not represent specific quantities and orders.

[0034] As Figures 1 to 5As shown in the figure, the present utility model provides a new type of anti-scald faucet. The new type of anti-scald faucet includes a faucet body 1. An inlet channel 2, an inlet switch 3 and an outlet channel 4 are arranged in the faucet body 1. The inlet channel 2 is communicated with an external pipeline. The inlet switch 3 is arranged on the inlet channel 2 to control the entry of external liquid into the liquid heating device. One end of the outlet channel 4 is directly communicated with the inside of the liquid heating device, and the other end of the outlet channel 4 is directly communicated with the outside, so that the inside of the liquid heating device is kept in air pressure balance with the outside. When the inlet switch 3 is opened, external liquid enters the liquid heating device, and the liquid heated in the liquid heating device is directly discharged from the outlet channel 4. Specifically, the liquid can be tap water or filtered water. The present utility model preferably uses filtered water. The liquid heating device can be a water heater or a water boiler. The present utility model preferably uses a water boiler. More specifically, the liquid inlet channel 2 includes a first inlet pipe 7 and a second inlet pipe 8. A water outlet joint 5 is arranged at the water outlet end of the faucet body 1, and the water outlet joint 5 is provided with a first water outlet 6. One end of the first inlet pipe 7 is communicated with the filtered water pipeline. The first inlet pipe 7 is used for filtered water to flow into the inlet switch 3. One end of the second inlet pipe 8 is connected to the water inlet of the water boiler. The second inlet pipe 8 is used for filtered water to flow into the water boiler. Through the inlet switch 3, the connection or disconnection between the first inlet pipe 7 and the second inlet pipe 8 is realized, which is convenient for people to open or close the filtered water flowing into the water boiler. One end of the outlet channel 4 is connected to the water outlet of the water boiler, and the other end of the outlet channel 4 is connected to the water outlet 6. The filtered water flows out from the water outlet 6 through the first liquid outlet passage after being heated. Since the pressure in the outlet channel 4 will change after the filtered water is heated, however, the present utility model can discharge the air pressure in the outlet channel 4 when the heated filtered water flows out from the first water outlet 6, so that the inside of the water boiler is kept in air pressure balance with the outside, and it is avoided that the heated filtered water is sprayed out from the water outlet 6 under the influence of air pressure. Therefore, through the above new type of anti-scald faucet, the air pressure can be discharged before the liquid flows out of the liquid heating device, avoiding the user being scalded by the sprayed liquid, and it can supply a variety of liquids to flow out.

[0035] In a specific embodiment, the inlet switch 3 includes a knob 9, a button 10, an elastic member 11 and a quick-opening valve core 12. The quick-opening valve core 12 has an integrated water passage for conducting the first inlet pipe 7 and the second inlet pipe 8 and between the two pipes. The knob 9 controls the rotation of the quick-opening valve core 12 through the elastic member 11. The elastic member 11 is preferably a spring. The button 10 is a switch for controlling the quick-opening valve core 12 and is used to control the rotation of the quick-opening valve core 12. More specifically, press the button 10 downwards and then rotate it forward. At the same time, the elastic member 11 rotates synchronously and remains unchanged at the front end. The first inlet pipe 7 and the second inlet pipe 8 are conducted through the quick-opening valve core 12, and drinking water gradually flows out from the first water outlet 6. When the hand is released, the knob 9 immediately rotates back, driving the quick-opening valve core 12 to close, and the drinking water will stop flowing out from the first water outlet 6.

[0036] In a specific embodiment, to facilitate the installation of the new anti-scald faucet on the sink, the new anti-scald faucet is provided with a connection assembly 13. The connection assembly 13 includes a connecting piece 14, a limiting piece 15 and a cover body 16. The outer surface of the connecting piece 14 is provided with threads to facilitate installation on the sink. The limiting piece 15 is sleeved on the connecting piece 14, and the limiting piece 15 is fastened to the sink by screws. The cover body 16 can move along the height direction of the connecting piece 14 and cover the limiting piece 15. When the cover body 16 covers the limiting piece 15, the overall aesthetics of the new anti-scald faucet can be improved.

[0037] In a specific embodiment, the faucet body 1 includes a water outlet body 17 and an installation body 18. The water outlet body 17 is detachably connected to the installation body 18. The water outlet end of the water outlet body 17 is connected to the water outlet joint 5. The installation body 18 is used to install the liquid inlet switch 3. The detachable design of the faucet body 1 facilitates the installation and maintenance of the pipeline, and also facilitates the installation and replacement of the liquid inlet switch 3.

[0038] As Figure 6 shown, in a specific embodiment, the present invention includes a drinking water output mode. The steps of the drinking water output mode are as follows: operate the liquid inlet switch 3 to connect the first liquid inlet pipe 7 and the second liquid inlet pipe 8. The filtered water enters the water heater through the first liquid inlet pipe 7 and the second liquid inlet pipe 8. After the filtered water is heated, the air pressure in the liquid outlet channel 4 is discharged first, so that the inside of the water heater is kept in air pressure balance with the outside world, and then it flows out from the water outlet 6 through the liquid outlet channel 4.

[0039] The present invention also provides a heating system for controlling the inflow and outflow of liquid. The heating system includes the new anti-scald faucet and also includes a liquid heating device. The liquid heating device is connected to the new anti-scald faucet.
