Description

Technical Field

[0001] This utility model belongs to the field of water cup technology, and in particular relates to an anti-scalding straw cup based on an electric valve. Background Technology

[0002] Existing straw cups typically employ simple temperature sensing mechanisms for scalding prevention. They completely shut off the water flow when the water temperature is too high and fully open it when the water temperature is low. However, they lack precise control over the water temperature in the intermediate range, resulting in a poor user experience. In addition, common technologies often use solenoid valves, which require continuous power to maintain the valve position, leading to high energy consumption. Therefore, there is a need for a scalding-proof straw cup that can accurately adjust the water flow based on the water temperature and is energy-efficient. Summary of the Invention

[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a scalding straw cup based on an electric valve.

[0004] To achieve the above objectives, the present invention adopts the following technical solution.

[0005] An anti-scalding straw cup based on an electric valve includes a cup body and a lid. The lid fits over the mouth of the cup body. The lid contains at least one electrically connected electric valve, a control module, a battery, and a temperature sensor. A straw assembly is connected to the electric valve. The electric valve controls the opening and closing of the straw assembly and regulates the water flow rate. The control module controls the electric valve. The battery provides power. The temperature sensor extends at least partially downwards through the bottom wall of the lid to detect the water temperature T inside the cup. The control module compares the water temperature T with preset room temperature threshold C1 and high temperature threshold C2. When T < C1, the control module fully opens the electric valve. When T > C2, the control module fully closes the electric valve. When C1 ≤ T ≤ C2, the control module controls the opening ratio P of the electric valve according to the water temperature T to regulate the water flow rate.

[0006] As a preferred option, when C1≤T≤C2, the relationship between the opening ratio P of the electric valve and the water temperature T is P=1-(T-C1)*10%.

[0007] Preferably, the electric valve is provided with an outlet and an inlet; the suction tube assembly includes an outlet pipe and an inlet pipe; the outlet pipe is connected to the outlet; and the inlet pipe is connected to the inlet.

[0008] Preferably, the side or top wall of the cup lid is also provided with a display screen that is electrically connected to the control module.

[0009] Preferably, the side or top wall of the cup lid is also provided with buttons that are electrically connected to the control module.

[0010] Compared with the prior art, the beneficial effects of this utility model are: The water temperature is detected in real time by a temperature sensor. The control module controls the opening and closing state and opening ratio of the electric valve based on the comparison between the water temperature and preset thresholds (normal temperature threshold C1 and high temperature threshold C2). This allows the valve to automatically close when the water temperature is too high to prevent scalding, and to fully open when the water temperature is suitable. The water flow is also linearly adjusted within the intermediate temperature range to improve safety and comfort. The electric valve maintains its state by cutting off power after reaching the target opening ratio, which is more energy-efficient than a solenoid valve and enables precise flow control, overcoming the limitations of existing technologies that can only be fully open or fully closed.

[0014] To make the technical solution of this utility model clearer, the following description is in conjunction with the appendix. Figures 1 to 3 This specification provides a detailed description of the present invention. It should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the scope of protection of the present invention. Example 1

[0015] A scalding-proof straw cup based on an electric valve, such as Figure 1 As shown, the cup includes a cup body 11 and a cup lid 12. The cup lid 12 covers the mouth of the cup body 11. The cup lid 12 is equipped with at least an electrically connected electric valve 3, a control module 4, a battery 5, and a temperature sensor 6. The electric valve 3 is used to control the opening and closing of the straw assembly 2 and can adjust the water flow rate. The straw assembly 2 includes a water outlet pipe 21 and a water inlet pipe 22. The water outlet pipe 21 is connected to the water outlet 31 of the electric valve 3, and the water inlet pipe 22 is connected to the water inlet 32 ​​of the electric valve 3. The control module 4 is used to control the operation of the electric valve 3. The battery 5 is used to power the electric valve 3, the control module 4, and the temperature sensor 6. The temperature sensor 6 passes through the bottom wall of the cup lid 12 to sense the water temperature T inside the cup 11.

[0016] Working principle (e.g.) Figure 2-3As shown): Temperature sensor 6 first detects the water temperature T inside the cup body 11 and feeds the water temperature T information back to control module 4. Control module 4 compares it with the preset temperature, which includes a normal temperature threshold C1 and a high temperature threshold C2. When T < C1 (e.g., 40℃), control module 4 can control electric valve 3 to fully open, adjusting the water flow to the maximum. When T > C2 (e.g., 50℃), control module 4 can control electric valve 3 to fully close, and the water flow will be zero, that is, the straw assembly 2 cannot dispense water, and the user cannot drink water, achieving high temperature anti-scalding protection. When C1 ≤ T ≤ C2, control module 4 controls the opening ratio P of electric valve 3 according to the water temperature T to adjust the water flow. The relationship between the opening ratio P of electric valve 3 and water temperature T is P = 1 - (T - 40) * 10%.

[0017] The electric valve 3 can be de-energized and maintained after reaching the target opening level, while the solenoid valve needs to be continuously energized to maintain the valve position. Therefore, the electric valve 3 has a more significant energy-saving advantage than the solenoid valve. Furthermore, the existing anti-scalding straw technology can usually only switch between two states: fully open or fully closed. The electric valve 3 can also precisely regulate the water flow.

[0018] Specifically, the electric valve 3 can be an electric needle valve, as shown in the Chinese utility model patent "A Novel Electric Needle Valve" (publication number CN207018546U). In addition to being able to be fully open and fully closed, the flow regulation and control are also more linear and precise.

[0019] Specifically, the electric valve 3 can also be an electric regulating valve (a product of Keppel Technology, with part number JB-F11, which is existing technology). Its basic structure is that the valve core is rotated by a stepper motor, which causes the valve core angle to change. There is an exponentially changing water flow channel on the valve core. When the valve core angle changes, the water flow cross section of the water flow channel changes accordingly, thereby changing the flow rate.

[0020] Specifically, in this embodiment, the battery 5 is a rechargeable battery and uses a non-removable structural design (of course, other batteries can also be used and designed as removable and replaceable structures); and the battery 5 is charged by setting a charging interface 7 on the side wall or top wall of the cup lid 12; this is prior art and will not be described in detail here.

[0021] Specifically, the side or top wall of the cup lid 12 is also provided with a display screen 8 electrically connected to the control module 4, which is used to display information such as water temperature T and the opening and closing status of the electric valve 3.

[0022] Specifically, the side or top wall of the cup lid 12 is also provided with a button 9 that is electrically connected to the control module 4. The button 9 can be used as a switch, and can be used to operate the room temperature threshold C1 and the high temperature threshold C2.

[0023] The above description is merely a specific example of this utility model and does not constitute any limitation on this utility model. Obviously, those skilled in the art, after understanding the content and principle of this utility model, may make various modifications and changes in form and details without departing from the principle and structure of this utility model. However, these modifications and changes based on the concept of this utility model are still within the protection scope of the claims of this utility model.
