The cavity of the inner cylinder 10 is the cavity 10a of the cup 100. The inner cylinder 10 is provided with a temperature sensor for monitoring the temperature in the cavity 10a.

A plurality of groups of semiconductor refrigeration assemblies 30 are arranged between the inner cylinder 10 and the side wall of the outer cylinder 20 at intervals around the circumference, and a control unit connected with the semiconductor refrigeration assemblies 30 and a temperature sensor is arranged on the outer cylinder 20, so that the control unit can control the running condition/state of the semiconductor refrigeration assemblies 30 so as to create a stable low-temperature environment in a cavity 10a on the inner cylinder 10. The temperature sensors may be provided in plurality and distributed at different depth positions of the cavity 10a, and the operation/working state of the semiconductor refrigeration assembly 30 is regulated by the control unit according to sensing signals fed back by the temperature sensors.

The semiconductor refrigeration assembly 30 may be a product of an existing model, and its structure belongs to the prior art, and this patent will not be repeated too much. As shown in fig. 1 to 4, the semiconductor refrigeration assembly 30 includes a first substrate 31 and a first flow guide strip 32, and a second substrate 34 and a second flow guide strip 33 disposed at both ends of a middle element unit 35 (including a semiconductor couple).

The wall body of the inner cylinder 10 is provided with a medium cavity 11, and the cold end of the semiconductor refrigeration assembly 30 corresponds to the medium cavity 11, so that the purpose of keeping the medium in the medium cavity 11 in a low-temperature state can be achieved. The medium filled in the medium cavity 11 can be ordinary water, purified water, and water-soluble high polymer like sodium polyacrylate.

The medium chambers 11 may be distributed on the side wall and the bottom wall of the inner cylinder 10 as shown in the figure, or may be distributed only on the side wall of the inner cylinder 10.

The cup 100 and the cover 200 may be detachably assembled, and may be screw-connected or magnetically-connected, in which a plurality of magnetic sheets are alternately arranged around the circumference on the upper end surface of the cup 100 (the outer cylinder 20), and correspondingly, iron blocks or iron rings corresponding to the magnetic sheets 21 may be embedded in the cover 200, or magnetic blocks corresponding to the magnetic sheets 21 may be embedded in the cover 200.

A tapered hole 10b is formed at the upper port of the inner cylinder 10, and a tapered boss is formed on the cover 200 correspondingly, and when the cavity 10a of the cup 100 is closed by the cover 200, the tapered boss can be inserted into the tapered hole 10b so that the sidewall of the tapered hole 10b contacts with the sidewall of the tapered boss. The conical boss can be made of elastic rubber, or an elastic layer is embedded on the side wall of the conical boss, or rubber rings are distributed at intervals along the axial direction.

Example 1

The outer cylinder 20 is made of a heat insulating material, and the inner cylinder 10 is made of a heat conducting/temperature conducting material, such as stainless steel or other metals. The semiconductor refrigeration assembly 30 is capable of refrigerating a medium (e.g., water, and will be described below as water) injected into the medium chamber 11 such that the water is maintained above/below a certain temperature value (e.g., 2 degrees celsius) in the range of 0 degrees celsius to 10 degrees celsius. The water conducts the low temperature to the whole inner cylinder 10 to form a constant low temperature space in the cavity 10a, so as to cool and store the medical spray.

Example two

Unlike the above embodiment, the inner cylinder 10 is also made of a heat insulating material in this embodiment, and a temperature guiding unit a12 is added to guide the low temperature to the cavity 10a. Compared with the embodiment, the whole energy consumption of the device can be remarkably reduced, and the time length of the cavity 10a in the device kept in a low-temperature state can be remarkably prolonged under the condition of single full charge.

A plurality of temperature guiding units A12 are distributed on the side wall of the inner cylinder 10. The distributed temperature guiding units A12 are distributed at intervals along the axial direction of the cavity 10a to form a plurality of circles (such as five layers), and each circle contains a plurality of temperature guiding units A12.

The temperature guiding unit a12 includes a metal plate 121, a plunger 123, a spring 124, and a metal plate 125.

One end of the metal sheet 121 extends into the medium chamber 11, and the other end is formed as an arm 122 and is fixed to the side wall of the inner cylinder 10. The free ends of the arms 122 extend into the cavity 10a.

An axial shaft hole is formed from an end surface of the arm lever 122, and the spring 124 is inserted into the shaft hole.

One end of the inserting rod 123 is inserted into the shaft hole of the arm rod 122, and the other end is fixedly connected with the metal disc 125. The axial length of the insert pin 123 is not smaller than the depth of the shaft hole in the arm 122.

One end of the spring 124 is fixedly connected to the inner bottom surface of the shaft hole on the arm lever 122, and the other end is fixedly connected to the insert rod 123, so that the insert rod 123 can have an axial stroke amount relative to the shaft hole on the arm lever 122.

In the initial state, the insert 123 is exposed to a certain axial length relative to the shaft hole on the arm 122, and when the insert 123 moves inward under the action of external force, the spring 124 is compressed, and a section of the insert 123 exposed to the outside of the (shaft hole) can at least partially or completely move into the shaft hole on the arm 122.

A plurality of rotating rollers 126 are distributed on the end surface of the metal plate 125, the rotating rollers 126 are made of metal (heat conducting/temperature conducting) materials, and the rotating rollers 126 are distributed on the metal plate 125 at intervals up and down along the vertical direction.

When the medical spray bottle 300 is placed in the cavity 10a or taken out from the cavity 10a, the rotating roller 126 contacts with the surface of the bottle body of the medical spray bottle 300, and friction is reduced by rotation, so that the medical spray bottle 300 can be smoothly placed in and taken out.

When the bottle body of the medical spray bottle 300 contacts the roller 126, the insert rod 123 can be pressed by the metal plate 125 to move into the shaft hole of the arm rod 122, thereby yielding. After the medical spraying bottle 300 is placed in the cavity 10a, the roller 126 on the metal disc 125 can be ensured to be tightly pressed on the bottle body by means of the elastic force of the spring 124, so that the medical spraying bottle 300 is ensured to be stably placed in the cavity 10a, collision with the inner wall of the cavity 10a in the carrying process is avoided, and the inner cavities of the medical spraying bottle 300 are all in a certain high-pressure state, so that the safety in carrying is ensured.

The arm 122, the insert 123, the roller 126, the metal plate 125, etc. may be made of the same metal material or may be made of different metal materials.

In a specific implementation, a rolling portion facing the inner wall of the cavity may be formed at both the upper end and the lower end of the metal plate 125. In this way, smooth insertion and removal of the spray bottle 300 into and from the cavity 10a can be better ensured.

To increase the heat conduction/heat conduction area, heat conduction fins are distributed on the back surface of the metal plate 125, i.e. the surface facing the inner wall of the cavity 10a.

Example III

Unlike the second embodiment, the present embodiment provides a temperature guiding unit of another structure, namely, a temperature guiding unit B13.

The plurality of heat conducting units B13 are uniformly distributed on the side wall of the inner cylinder 10 around the circumference at intervals. The heat conducting units B13 are elongated and distributed along the axial direction of the cavity 10a.

The heat conduction unit B13 includes a wedge noodle 131, a metal plate 132, and a arcuate plate 133. The wedge noodle 131, the metal plate 132, and the arcuate plate 133 may be made of the same metal material or may be made of different metal materials.

The wedge surface on the wedge strip 131 gradually leans against the change trend of the axial lead of the cavity 10a from top to bottom.

The metal plate 132 is fixed to an end surface of the wedge strip 131 facing away from the wedge surface, and the arcuate plate 133 is provided on the wedge surface of the wedge strip 131. At least one end of the arcuate plate 133 is slidable with respect to the wedge surface of the wedge noodle 131.

The wedge strip 131 extends into the cavity 10a. The metal plate 132 is fixed to the side wall of the inner cylinder 10 and partially protrudes into the medium chamber 11. An end surface of the wedge strip 131 facing away from the wedge surface can be brought into close contact with a side wall surface of the cavity 10a.

As shown in fig. 5 and 6, the arcuate plate 133 has an arcuate surface protrusion 1331 at both upper and lower ends thereof, and the arcuate surface of the arcuate surface protrusion 1331 is brought into contact with the wedge surface of the wedge noodle 131. When the medical spray bottle 300 is placed in the cavity 10a, the bottle body presses the arch surface of the arch plate 133, as shown in fig. 5, the pressing forces F1 and F2 act on the arch surface of the arch plate 133, so that the two ends of the arch plate 133 slide relative to the wedge surface of the wedge noodle 131, respectively move up and down at the speed V, the arch width of the arch plate 133 gradually becomes smaller, and the arch plate 133 gradually leans against and eventually can at least partially contact the wedge surface of the wedge noodle 131. The pressing forces F1 and F2 indicate that the forces applied to the arch plate 133 are changed in different degrees of deformation, and obviously, F2 > F1. With the removal of the spray bottle 300, the dome plate 133 can be restored to its original shape.

Grooves 1311 having a long shape along the axial direction of the cavity 10a are provided at the upper and lower portions of the wedge surface 131, respectively. The upper end of the arcuate plate 133 is inserted into the groove 1311 at the upper portion and contacts the bottom surface of the groove 1311, so that the upper end of the arcuate plate 133 can slide with respect to the groove 1311. The lower end of the arcuate plate 133 is inserted into the groove 1311 at the lower portion and contacts the bottom surface of the groove 1311, so that the lower end of the arcuate plate 133 can slide with respect to the groove 1311. In the drawing, slide grooves 1312 are provided on the side walls of the two grooves 1311, and shaft portions 1332 corresponding to the slide grooves 1312 are provided at the upper and lower ends of the arcuate plate 133. The slot 1312 is L-shaped to facilitate insertion of the shaft portion 1332 into the slot 1312. The inner bottom surface of the chute 1312 may be a slant or a flat surface.

The arcuate plate 133 may be fixed to an upper portion of the wedge surface 131 at an upper end thereof, and may be slidably fitted to a groove 1311 provided at a lower portion thereof with respect to the wedge surface of the wedge surface 131.

The arcuate plate 133 is outwardly directed and is opposed to the axis of the cavity 10a.

As shown in fig. 8, a plurality of metal balls 1334 are fitted in the arcuate surface of the arcuate plate 133. The arcuate plate 133 is provided with a locking groove 1333, and the metal ball 1334 is fitted in the locking groove 1333.

In the third embodiment, by means of the deformation of the arch plate 133, on one hand, the medical spray bottle 300 can be firmly limited in the cavity 10a, collision between the medical spray bottle 300 and the cavity 10a is prevented, and on the other hand, a larger contact surface can be established with the wedge surface of the wedge noodle 131, so that a good heat conduction purpose is achieved.

As shown in fig. 7, the heat dissipation unit 50 further includes a heat dissipation unit 50, and the heat dissipation unit 50 includes a heat conduction plate 51 and a heat conduction sheet 52 made of metal materials.

The side wall of the outer cylinder 20 is provided with a plurality of sinking grooves 23, the sinking grooves 23 are alternately distributed along the axial direction/the vertical direction to form a plurality of layers, and each layer contains a plurality of sinking grooves 23 alternately distributed around the circumference.

The heat dissipation units 50 are matched with the sink grooves 23 in a one-to-one correspondence.

The heat-conducting sheet 52 is embedded in the wall of the outer cylinder 20 opposite to the hot end of the semiconductor refrigeration assembly 30 to transfer and conduct the heat emitted from the hot end to the outside.

One end of the heat conduction plate 51 is fixed to the wall of the outer cylinder 20 and connected to the heat conduction sheet 52, thereby forming a heat transfer path. The other end of the heat conducting plate 51 extends into the sink 23, so that the free end of the heat conducting plate 51 is retracted inwards relative to the sink 23.

The heat dissipation area may be increased by correspondingly matching a plurality of heat conductive plates 51 for each heat conductive sheet 52 and arranging the plurality of heat conductive plates 51 alternately in the vertical direction or arranging the plurality of heat conductive plates 51 alternately laterally. Metal fins 53 may be further provided on the plate body of the heat conductive plate 51 to further increase the heat dissipation area.

The sink 23 may be extended in a vertical direction by a certain length. The countersink 23 may have a trapezoidal cross section (as shown in fig. 7) with the flared end facing outwardly.

The scheme of the third embodiment needs to be described as follows:

after the medical spray bottle 300 is placed in the cavity 10a, the arcuate plate 133 is at least partially in contact with the wedge surface of the wedge noodle 131.
