Specific embodiment

The present invention will be described in further detail below with reference to the embodiments of the drawings.

Embodiment 1

As shown in fig. 1~fig. 5, the cup of Stirling engine is had on a kind of cup lid, including cup body 101 and is covered on this Cup lid on cup body 101, cup lid include lid 20, and lid 20 is equipped with Stirling engine unit 10, and the outside of lid 20 is de- It is equipped with a cover 100 with unloading formula, Stirling engine unit 10 is then located in the cover 100.

The heat-absorbent surface 14 of Stirling engine unit 10 can absorb heat on the inside of lid 20.Lid 20 includes ontology 4 and is set to Collet 5 in ontology 4, the heat-absorbent surface 14 of Stirling engine unit 10 and ontology 4 are seperated part, lid 20 further include one every Hot lid 6, the insulation cover 6 can open and close ground and be set to 5 lower end of collet.5 inner wall of collet has internal screw thread, accordingly, insulation cover 6 Threaded portion 61 has the external screw thread being adapted to internal screw thread, also, the threaded portion 61 of insulation cover 6 has multiple longitudinal air channels 62。

The mounting hole that there is the heat-absorbent surface 14 for Stirling engine unit 10 to protrude into the middle part of ontology 4,5 upper surface of collet The seal groove 51 of an annular is formed around mesoporous, is equipped with sealing ring 7, the suction of Stirling engine unit 10 in the seal groove 51 Hot face 14 is matched with 5 upper surface of collet.

As shown in Figure 6 and Figure 7, the Stirling engine unit 10 in the present embodiment include the first cylinder 1, the second cylinder 2, Bracket 32, flywheel 3, the first crank 12, the second crank 22, first piston 15 and second piston 25,1 lower end surface of the first cylinder are formed Heat-absorbent surface 14, upper surface form radiating surface 13；Second cylinder 2 is connected to the first cylinder 1；Bracket 32 is longitudinal to be set to the first cylinder 1 Upper surface；Flywheel 3 is set on bracket 32 with being able to rotate by a central axis 31, and bracket 32 is equipped with bearing 33, central axis 31 Extend through the setting of bearing 33；First crank 12 is set to 31 one end of central axis, and the second crank 22 is set to 31 other end of central axis；The One piston 15 can be set to up or down in the first cylinder 1 and upper end is connected by first connecting rod 11 and 12 eccentric position of the first crank It connects；It is eccentric by second connecting rod 21 and the second crank 22 that second piston 25 can be set in the second cylinder 2 and upper end up or down Position connection.

In use, warm water or boiling water are added into cup body 101, cover 100 is taken, cup lid is placed on cup body 101, rather Zhong Hou makes the first cylinder 1 and the second cylinder 2 be respectively formed hot cylinder and cold cylinder, makes being mutually shifted for two pistons, and work is situated between Matter flows back and forth between two cylinder 2 of the first cylinder 1 and the mat woven of fine bamboo strips, completes four cyclic processes:

1. constant volume endothermic process, first piston 15 and second piston 25 are in, bottom dead center position is motionless, the first cylinder Temperature increases in the case of lower partial air realizes constant volume, and 1 low pressure of the first cylinder increases.

2. fixed temperature expansion process, second piston 25 is in that bottom dead center position is motionless, and first piston 15 is by lower dead center Uplink, the air of the lower part of the first cylinder 1 passes through the heating of the first cylinder 1 therebetween, absorbs heat, maintains temperature-resistant.

3. constant volume exothermic process, first piston 15 and the second piston 25 entire stroke of uplink at a same speed, respectively reach To top dead centre, air is partially shifted under the second cylinder 2 part from the first cylinder 1 in constant volume, i.e., is pushed away from hot gas room To cold air chamber, heat is outwardly released, declines air themperature, part air pressure increases on the second cylinder 2.

4. determining temperature and pressure compression process, the downlink by top dead centre of second piston 25 compresses the air in the second cylinder 2, maintains Temperature of Working is constant, increases part air pressure under the second cylinder 2, to push 15 downlink of first piston.It is returned in this way Original state completes a closed circulation.

In the above process, on startup, needs to be dialled with hand or other modes make flywheel 3 have centainly initial Speed.Opening and closing heat transfer may be implemented by rotating insulation cover 6, when unscrewing, hot-air can enter from air channel 62, thus by Heat-absorbent surface 14 absorbs.

Embodiment 2

As shown in Figure 8 and Figure 9, in the present embodiment, the difference from embodiment 1 is that, Stirling engine unit 10 Heat-absorbent surface 14 is integrated with ontology 4, i.e. 4 upper surface of the ontology heat-absorbent surface 14 that is Stirling engine unit 10.

Embodiment 3

As shown in Figure 10 and Figure 11, in the present embodiment, the difference from embodiment 1 is that, the cup packet in the present embodiment The cup lid for including cup body 101 and being covered on the cup body 101, and Stirling engine unit 10 itself is used as cup lid.

The lateral wall 16 of first cylinder 1 of Stirling engine unit 10 snaps onto the rim of a cup 1011 of 101 upper end of cup body. When Stirling engine unit 10 and 1011 complete clamping of rim of a cup, the sealing effect of cup is also best.Alternatively, Stirling engine unit 10 can also be using the scheme in embodiment 7~11.

In order to enable the connection sealing of buckle-type can be more preferable, and as shown in figure 12, the first of Stirling engine unit 10 The upper edge of the lateral wall 16 of cylinder 1 is provided with first magnetic part of circle 163, is inlaid with the first buckle on the first magnetic part 163 Sealing ring 164 on the position corresponding with the first magnetic part 163 of rim of a cup 1011, is provided with second magnetic part of circle 1014, when covering When cup lid, two magnetic parts are attracted each other, to the first buckle sealing ring 164 be pushed down, to achieve the effect that sealing.Herein Two magnetic parts caused by magnetic field the magnetic parts in Stirling engine unit 10 will not be had an impact or be influenced Very little.

In order to enable the connection sealing of buckle-type can be more preferable, a kind of alternative scheme is as shown in figure 13, Stirling hair At least one second buckle sealing ring 165, the second buckle sealing are arranged on the lateral wall 16 of first cylinder 1 of motivation unit 10 Circle 165 is made of rubber elastomeric material, rim of a cup 1011 is squeezed by the elasticity of the second buckle sealing ring 165, so that Stirling The junction of engine unit 10 and rim of a cup 1011 seals.

The basic principles, main features and advantages of the present invention have been shown and described above.The technology of the industry Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and what is described in the above embodiment and the description is only the present invention Principle, various changes and improvements may be made to the invention without departing from the spirit and scope of the present invention, these variation and Improvement is both fallen in the range of claimed invention.The present invention claims protection scope by appended claims and its Equivalent defines.
