Referring to fig. 1-3, a accuse temperature bowl cover, including teacup 1 and bowl cover

main part

2, 2 threaded connection of bowl cover main part are in the top of teacup 1, the top of teacup 1 is equipped with the standing groove, the thermovent 3 has been seted up on the bowl cover main part 2, the top fixed mounting of teacup 1 has dust screen 4, dust screen 4 is located thermovent 3 directly over, and dust screen 4's external diameter is greater than the internal diameter of thermovent 3, a plurality of louvres have been seted up on dust screen 4, when convenient radiating, avoid some little winged insects to get into in the tea.

The heat dissipation port 3 is communicated with the placing groove, two installation cavities 5 communicated with the heat dissipation port 3 are symmetrically arranged in the cup cover main body 2 from left to right, heat insulation plates 6 are connected in the two installation cavities 5 in a sliding mode, one opposite sides of the two heat insulation plates 6 are located in the heat dissipation port 3, one opposite sides of the two heat insulation plates 6 are fixedly connected with a first sealing block 7 and a second sealing block 8 respectively, the first sealing block 7 is located above the second sealing block 8, the first sealing block 7 and the second sealing block 8 are matched with each other, a groove is formed below the first sealing block 7, a plurality of soft metal sheets are hinged to the bottom of the groove, a cavity is formed in each metal sheet, a convex block is arranged above the first sealing block 7 and is connected with the groove in a sliding mode, the convex block can impact the metal sheets when sliding, and sounds are; the heat insulation plate 6 is made of ceramic materials, the ceramic materials have good heat insulation effect, and the temperature of the tea water can be insulated.

Equal longitudinal symmetry is equipped with two spouts 11 in two installation cavity 5, is equipped with loop bar 14 in the spout 11, and the both ends of loop bar 14 respectively with the inner wall fixed connection of the 11 left and right sides of spout, sliding connection has slide 12 on loop bar 14, has seted up the sliding opening on slide 12, and sliding opening inner wall fixed mounting has the sliding ring, and slide 12 passes through sliding ring and loop bar 14 sliding connection, reduces the frictional force between loop bar 14 and slide 12 through the sliding ring.

One side that two slides 12 carried on the back mutually respectively with heat insulating board 6 both sides fixed connection from top to bottom, equal fixed mounting has heat conduction box 9 on the upper and lower side inner wall of the position that installation cavity 5 is close to thermovent 3, two heat conduction boxes 9 cooperation heat insulating board 6 seal installation cavity 5, both sides offset with two heat conduction boxes 9 respectively about heat insulating board 6 to with heat conduction box 9 sliding connection, both sides all offset with the inner wall of installation cavity 5 around the heat conduction box 9.

The heat conduction box 9 is positioned between the heat dissipation port 3 and the sliding plate 12, a mounting groove is arranged on one side of the heat conduction box 9 close to the sliding plate 12, an air bag 10 is fixedly mounted in the mounting groove, the air bag 10 is in a cuboid shape, the air bag 10 is made of a nylon material, the air bag 10 is filled with air, the volume of the air can be changed at different temperatures, the expansion coefficient of the air is 3.676 x 10^ -3, when the temperature of tea water is 100 ℃, the volume of the air is assumed to be v1, under the condition that the pressure is unchanged, PV ═ nRT is constant, the pressure is increased by 1 ℃, the volume expansion is 1/273 times of 0.366 times, when the temperature of the tea water is 100 ℃, the volume of the air in the air bag 10 is expanded to be 1.3663 times of the state of 0 ℃, because the air bag 10 is limited by the mounting groove, the air bag expands towards the notch of the mounting groove through the mounting groove, the expansion force of the air bag 10 overcomes the elastic force of the return spring 13 and the friction force of the loop, thereby pushing the slide plate 12 to slide along the loop bar 14 toward the return spring 13, compressing the return spring 13, and the two heat insulation plates 6 are thus moved away from each other, and the heat dissipation port 3 is opened.

When the temperature is gradually reduced, the volume of the gas in the air bag 10 is gradually reduced, the two sliding plates 12 move towards one side far away from the return spring 13 under the action of the elastic force of the return spring 13, so that the two heat insulation plates 6 start to move oppositely, when the temperature of hot gas is reduced to 80 ℃, the temperature is 1.2930 times of the volume of the hot gas at the state of 0 ℃, and at the moment, a gap still exists between the two heat insulation plates 6 for continuous heat radiation; when the temperature reaches 60 ℃, the volume of the gas in the air bag 10 is 1.2198 times of the state of 0 ℃, the return spring 13 recovers to the original length, and the two first sealing blocks 7 and the second sealing block 8 are matched to make a sound to remind a user; one side of the air bag 10 far away from the heat conduction box 9 is abutted against the sliding plate 12, the inner wall of one side of the sliding groove 11 is fixedly provided with a return spring 13, and the other end of the return spring 13 is fixedly connected with the sliding plate 12.

In the invention, when a user uses the device, the user makes tea in the teacup 1 by using boiling water, after the tea making is finished, the cup cover main body 2 is screwed above the teacup 1, at the moment, the reset spring 13 enables a certain distance to exist between the two heat insulation plates 6, the heat insulation plates are matched with the heat dissipation port 3 to dissipate heat of tea in the teacup 1, and the dust screen 4 can prevent some winged insects from falling into the teacup 1 by hot air to affect the tea.

The tea water temperature in the teacup 1 is 100 ℃, the hot air temperature is also 100 ℃, the hot air heats the four heat conduction boxes 9 through the heat dissipation port 3 and transfers the temperature to the air bag 10, so that the air in the air bag 10 is heated, the volume of the air at different temperatures can be changed, the expansion coefficient of the air is 3.676 x 10^ -3, at 0 ℃, the volume of the air is v1, under the condition that the pressure is not changed, the PV ═ nRT is constant, the pressure is increased by 1 ℃, the volume expansion 1/273 times is 0.366 times, the expansion coefficient is further increased along with the temperature increase, at 100 ℃, the volume of the air in the air bag 10 is expanded to 1.3663 times of the state of 0 ℃, because the air bag 10 is limited by the installation groove, the sliding plate 12 is expanded towards the notch of the installation groove, and the sliding plate is pushed to slide along the loop bar 14 towards the reset spring 13, the return spring 13 is compressed, the two heat shields 6 are thus moved away from one another and the heat-dissipating opening 3 is opened.

When the temperature reduces gradually, the gaseous volume diminishes in the gasbag 10 gradually, two slides 12 can move towards one side of keeping away from reset spring 13 under reset spring 13's elasticity effect, thereby make two heat insulating boards 6 begin to remove in opposite directions, when the steam temperature reduces to 80 ℃, the volume is 1.2930 times of 0 ℃ state volume this moment, there is still the breach to continue the heat dissipation between two heat insulating boards 6 this moment, 60 ℃ this moment, the gaseous volume is 1.2198 times of 0 ℃ state in the gasbag 10 this moment, reset spring 13 resumes original length this moment, and two first enclosed mass 7 and the cooperation of second enclosed mass 8, seal thermovent 3, sound reminds the user.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
