A kind of temperature prompt vacuum cup
Technical field
The present invention relates to cups, more particularly to a kind of temperature prompt vacuum cup.
Background technique
Existing vacuum cup, usually double-layer structure or the thicker structure of wall thickness, based on double-layer structure.And the double-deck knot
The vacuum cup of structure, generally will not temperature indicator, can only armrest touch the outer wall of cup and carry out sense temperature, and it is preferable for heat insulation effect
Vacuum cup, heat insulation is preferable, and the temperature of outer wall is difficult have large change.And want to judge the temperature in vacuum cup, just can only
By opening cup lid, then go to experience the water temperature in cup with tongue or skin, in this way, tongue can be hurt when water temperature is higher
Or skin, it is dangerous.
Summary of the invention
Based on this, the object of the present invention is to provide a kind of temperature prompt vacuum cups, and vacuum cup water temperature can be shown by having
The advantages of.

Specific embodiment
In the description of the present invention, unless otherwise indicated, the meaning of " plurality " is two or more.
Embodiment:
A kind of temperature prompt vacuum cup as shown in Figure 1 to Figure 4, including cup body 20 and cup lid 10, the cup body 20 are metal material
The cylindrical structure of matter, and cylindrical groove 21 is formed in the bottom surface of the cup body 20, the cup body 20 is double-deck sky
Core structure;The cup lid 10 is the cylindrical structure that section is " mountain " font, and the middle part for being somebody's turn to do the cup lid 10 of " mountain " font is formed with
Columned raised 11, which can be fastened in the groove 21, and the formation for being somebody's turn to do the cup lid 10 of " mountain " font has annular
Groove body, is formed with internal screw thread at the groove body, and the cup lid 10 can be connected to the opening of the cup body 20 by the internal screw thread;
The cup lid 10 is hollow structure, and control circuit, the first temperature sensor and display are provided in the cup lid 10
Unit is formed with metal coating on the surface of the groove body of the annular of the cup lid 10, and first temperature sensor is tightly attached to this
On first temperature sensor, and first temperature sensor and the display unit are electrically connected with the control circuit respectively
It connects, the control circuit receives the temperature signal of first temperature sensor and is shown on the display unit;
It is provided with second temperature sensor in the cup body 20, which is tightly attached to the cup body 20
Between the double-deck wall body, and it is located on the inner wall of the cup body 20;Electricity there are two being respectively set in the groove 21 of the cup body 20
Two electrodes of contact, the second temperature sensor are connect with two electric contacts respectively;In the protrusion 11 of the cup lid 10
There are two guide ring, two guide rings to be electrically connected respectively with two electric contacts for setting;Two guide rings respectively with
The control circuit electrical connection, two guide rings are used to conduct the temperature signal of the second temperature sensor.
Two electric contacts are separately positioned on the bottom surface of the groove 21, and two guide rings are separately positioned on institute
State the top surface of protrusion 11.
The display unit is display screen or the display unit is Color-changing lamp.When using display screen, temperature signal
It is shown by digital form;When using Color-changing lamp, temperature signal is transferred to control circuit, and control circuit controls in Color-changing lamp
Associated light part shines, to show different colors.It is provided with button cell, in control circuit to provide power supply.
Sealing ring is provided in the annular groove of the cup lid 10.
Wall thickness at the annular groove of the cup body 20 is greater than the side wall wall thickness of the cup body 20.The wall thickness of annular groove is larger,
And it is greater than the wall thickness of side wall, it just can guarantee heat insulation when using as vacuum cup, thermal insulation property is more preferable.
Raised 11 diameter is identical as the diameter of the groove 21.
The working principle of the invention:
When cup lid 10 is fastened in the opening of cup body 20, cup lid 10 is connect by screw thread with the cup body 20, is then led to
Cross sealing ring sealing.The metal coating of the groove body of the annular of the annular in cup lid 10 is contacted with the air in cup body 20 at this time, if
Hot water is contained in cup body 20 at this time, hot-air will make the temperature of metal coating increase, and metal is the good conductor of heat, and heat is just
It can be transmitted to by metal coating on the first temperature sensor, the first temperature sensor will obtain the temperature value in cup body 20,
To be converted to temperature value to control circuit, temperature signal is transferred to display unit and shown by control circuit.Such case
Under, it is used as vacuum cup, to remind the temperature conditions in user's cup.
And when the groove of cup body 20 21 is connected on cup lid 10, it is used at this time as ordinary cup.Temperature in cup body 20
Degree is detected by second temperature sensor, is then conducted by electric contact to guide ring, then be transmitted in control circuit, from
And temperature signal can be shown in display unit, convenient for users to understanding.
And as a kind of preferred embodiment of the invention, when the temperature in cup body 20 reaches the temperature that suitable people drinks
(being lower than 40 DEG C), display unit shows green light or other remind display.
A kind of variant embodiment of the invention:
Two electric contacts are separately positioned on the side wall of the groove 21, and two guide rings are separately positioned on institute
State the side wall surface of protrusion 11.
The bottom surface of the groove 21 is arranged in one in two electric contacts, and the side of the groove 21 is arranged in another
Wall;Raised 11 top surface is arranged in one in two guide rings, and raised 11 side wall surface is arranged in another;
The electric contact of 21 bottom surface of groove can be abutted with the guide ring of raised 11 top surface, and the electric contact of 21 side wall of the groove
It can be abutted with the guide ring of raised 11 side wall surface.
The present invention not only realizes the temperature display of vacuum cup, also achieves 20 temperature-prompting of cup body of vacuum cup, convenient
User understands the water temperature in cup body 20, to conveniently drink.
The embodiments described above only express several embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously
It cannot therefore be construed as limiting the scope of the patent.It should be pointed out that coming for those of ordinary skill in the art
It says, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to protection of the invention
Range.
