Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail below. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without making any creative effort, shall fall within the protection scope of the present application.
Example one
The present embodiment provides a hot water kettle displaying a water amount, as shown in fig. 1, the hot water kettle displaying the water amount comprising: the kettle comprises a kettle body 1, an attitude sensor 2 positioned on the kettle body 1, a calculation unit 3 and a display screen 4; wherein:
the attitude sensor 2 is used for monitoring the inclination angle of the kettle body when the kettle body inclines, and the calculating unit 3 is used for calculating the water storage capacity in the kettle body 1 based on the inclination angle and the structural data of the kettle body 1 and displaying the information of the water storage capacity through the display screen 4.
Specifically, a posture sensor 2 and a calculation unit 3 may be installed in the handle of the hot water kettle, and the posture sensor 2 is used to acquire the inclination angle of the kettle body 1 when the kettle is poured. As shown in figure 2, since the horizontal plane passes through the water outlet of the kettle body 1 during the pouring process of the hot water kettle, the volume capacity of water in the hot water kettle can be indirectly determined by monitoring the inclination angle of the kettle body 1. And the specific value of the volume capacity can be calculated by the inclination angle of the kettle body 1 and the structure data (mainly the size data of the inner volume) of the kettle body 1 by using geometry. After the attitude sensor 2 monitors the inclination angle of the kettle body 1, the inclination angle value is transmitted to the calculating unit 3, and the calculating unit 3 calculates the residual water storage capacity of the hot water kettle after water pouring according to the inclination angle of the kettle body 1 and the structural data of the kettle body 1. Of course, there is a simpler way to calculate the water storage capacity, that is, the kettle body 1 with a specified internal volume structure is simulated to simulate the residual water storage capacity corresponding to different inclination angles when pouring water, and then the residual water storage capacity corresponding to any inclination angle when pouring water can be quickly determined by a table look-up similar way. Finally, the calculating unit 3 displays the calculated water storage amount information through the display screen 4 to be displayed to the user. For example, the display screen 4 may be mounted on the side of the kettle body to display the percentage of water remaining.
In a specific embodiment, the attitude sensor 2 may specifically include a gyroscope and an angular accelerometer, and is configured to monitor an angular velocity and an angular acceleration of the kettle body 1 when the kettle body 1 is tilted each time, and calculate a maximum tilt angle of the kettle body 1 when the kettle body is tilted based on the angular velocity and the angular acceleration; correspondingly, the calculating unit 3 is used for calculating the water storage capacity in the kettle body 1 based on the maximum inclination angle of the kettle body 1 when the kettle body 1 is inclined every time and the structural data of the kettle body 1, and displaying the information of the water storage capacity through the display screen 4.
In the practical application scenario, when the hot water kettle pours water every time, the water storage amount corresponding to the maximum inclination angle generated in the water pouring process is usually the remaining water storage amount in the kettle body 1 after the water pouring is completed, so that the volume state of the remaining water storage amount in the kettle body 1 can be determined by the inclination angle in the state at the time. Then, the calculation unit 3 calculates the volume of the remaining liquid, i.e. the amount of water remaining in the kettle body 1 after the water is poured the next time, based on the maximum inclination angle determined by the attitude sensor 2 and according to geometry.
In an embodiment, the thermos that displays the water amount further includes: a base 5 used for connecting with the commercial power, and a heating device is arranged at the bottom of the kettle body 1; when the bottom of the kettle body 1 is contacted with the base 5, the heating device is electrically connected with the base to be powered on and heat the water in the kettle body.
Specifically, after the base 5 is connected with the mains supply, the kettle body 1 is placed on the base 5, the water boiling is started, the mains supply provides electric energy for the heating device through the base 5, and therefore the heating device is driven to heat the water in the kettle body 1. When the water is boiled or the user actively controls to stop boiling the water, the electric connection between the heating device and the base 5 is disconnected, and the water boiling is finished.
In an embodiment, the thermos that displays the water amount further includes: a switching circuit (not shown) on the base 5 for controlling the mains supply to supply power to the heating device when the water is boiled; when the water is not boiled, the commercial power is controlled to be converted into low voltage to supply power to the display screen.
Specifically, after the base 5 is connected with the mains supply, the user places the kettle body 1 on the base 5, starts to boil water (presses a water boiling switch), and the switching circuit controls the mains supply to supply power to the heating device, so that the heating device is driven to heat the water in the kettle body 1. When the water is boiled or the user actively controls to stop boiling, the switching circuit can control the commercial power to be converted into low voltage so as to supply power to the display screen 4. The display screen 4 can not only display the residual water storage capacity in the kettle body 1, but also display other set information, such as information for reminding the completion of water boiling, water temperature (a temperature sensor needs to be additionally arranged) and the like.
In an embodiment, the thermos that displays the water amount further includes: and the relay (not shown in the figure) is used for detecting whether the hot water kettle is in a water boiling state or not and controlling the working state of the switching circuit.
Specifically, when the user starts to boil water (for example, presses a water boiling switch) or finishes boiling water (for example, lifts the water boiling switch), a switching signal can be transmitted to the relay, so that the working state of the switching circuit is triggered by the switching state of the relay.
In an embodiment, in the above thermos for displaying water amount, a status indicator lamp 6 may be installed on the base 5 for displaying the water boiling status of the thermos. For example, the status indicator lamp 6 is turned on when water is boiled, and the status indicator lamp 6 is turned off when water is not boiled (including after water is boiled).
In a specific embodiment, in the above thermos for displaying water amount, the kettle body 1 is further provided with a power module 7 for supplying power to the attitude sensor 2, the calculating unit 3 and the status indicator lamp 6.
For example, when the kettle body 1 is placed on the base 5 and electrically connected, the power module 7 can supply power to the status indicator lamp 6 to enable the status indicator lamp 6 to light up. The supply of power to the status indicator lights 6 by the power module 7 ensures that the status indicator lights 6 can only be illuminated when the kettle body 1 is placed on the base 5 and electrically connected, thereby avoiding indicating a false water boiling status.
In an embodiment, the thermos bottle with a water volume display function may further include: the measurement starting module (not shown) on the kettle body 1 is used for controlling the attitude sensor 2 to monitor the inclination angle of the kettle body 1 when the kettle body 1 is separated from the base 5 and the mains supply is disconnected, placing the kettle body 1 on the base 5, and sending the monitored maximum inclination angle to the computing unit 3 after the mains supply is connected. Like this, can control gesture sensor 2 through measuring the start module and just start the function of monitoring the 1 inclination of the kettle body when the user picks up the thermos and pours water, avoid extra operation, save the resource.
In an embodiment, in the above thermos displaying water amount, when the thermos is in a water boiling state, the mains power charges the power module 7. The power module 7 can be a rechargeable battery, and when the hot water kettle is connected with mains supply to boil water, the mains supply can be introduced to charge the power module 7, so that the power module 7 is ensured to be full of electric quantity.
In a specific embodiment, in the above-mentioned thermos that displays the water amount, the kettle body 1 is further provided with a buzzer for giving an alarm when the angular acceleration measured by the angular accelerometer when the kettle body 1 is inclined is greater than a specified threshold.
For example, considering that the user may be scalded due to too fast water pouring, when the angular acceleration measured by the angular accelerometer exceeds a certain critical value, the buzzer is activated to prompt the user, so as to prevent the hot water from being spilled out and causing unnecessary accident injury.
The use process of the thermos with the water quantity display is as follows:
when the user starts to boil water, the attitude sensor 2, the calculation unit 3 and the display screen 4 do not intervene in the work and are in a sleep state. In the process of boiling water, the hot water kettle charges the power module 7 by using commercial power, and if the power module 7 is full of electric quantity, the hot water kettle is not charged any more. After the water boiling is finished, the switching circuit is triggered and switched by the relay, the display screen 4 obtains electric energy to display that the water boiling is finished, and at the moment, because the user does not pour water, the residual data of the water is not displayed. When a user picks up the hot water kettle and begins to pour water, the kettle body 1 is separated from the base 5, the mains supply is disconnected, the attitude sensor 2 and the calculation unit 3 begin to calculate the angle and the angular speed at a fixed frequency, and the maximum inclination angle of the hot water kettle is recorded and stored. After the user finishes the pouring operation and the kettle is reset to the base 5, the calculating unit 3 calculates the volume of the liquid in the kettle body 1, namely the water storage capacity, according to the measured maximum inclination angle, and displays the percentage of the residual water storage capacity to the volume of the hot water kettle in the display screen 4. When a user pours water, if the maximum inclination angle of the kettle body 1 is larger than or equal to 90 degrees, the water in the kettle is defined to be poured out, no water is left in the kettle, the attitude sensor 2 and the calculation unit 3 enter a sleep mode, and the display screen 4 displays no water.
In addition, when a user pours water, if the angular acceleration measured by the angular accelerometer when the kettle body 1 is inclined is larger than a specified threshold value, the buzzer is triggered to give an alarm to prompt the user, so that the situation that hot water is spilled out to cause unnecessary accident injury is avoided.
The hot water kettle capable of displaying the water quantity comprises a kettle body, an attitude sensor, a calculating unit and a display screen, wherein the attitude sensor is positioned on the kettle body; through inclination when the gesture sensor monitoring kettle body takes place to incline, the computational unit calculates the water storage capacity in the kettle body based on the structure data of inclination and the kettle body to show the information of this water storage capacity through the display screen, look over the water storage capacity in the kettle body with the convenience of customers. The scheme can quickly and accurately calculate the water quantity in the hot water kettle based on the inclination angle of the kettle body and the structural data of the kettle body when water is poured, and does not need to adopt a special manufacturing process for the kettle body, thereby saving the manufacturing cost.
