[0022] The following will describe a thermal insulation sleeve and a thermal insulation system of the present utility model in more detail with reference to the schematic diagrams, in which the preferred embodiments of the present utility model are shown. It should be understood that those skilled in the art can modify the present utility model described herein while still achieving the advantageous effects of the present utility model. Therefore, the following description should be understood as a broad guidance for those skilled in the art and not as a limitation to the present utility model.

[0023] In the following paragraphs, the present utility model will be described more specifically by way of example with reference to the accompanying drawings. The advantages and features of the present utility model will be clearer according to the following description and the claims. It should be noted that the drawings are all in a very simplified form and use non-precise scales, only for the purpose of conveniently and clearly assisting in explaining the purpose of the embodiments of the present utility model.

[0024] As Figure 1 shown, this embodiment proposes a thermal insulation sleeve, including: a sleeve outer shell 1 and a sleeve inner claw 2; a first tapered thread 4 is provided on the inner wall surface of the sleeve outer shell 1; a second tapered thread 5 is provided on the outer wall surface of the sleeve inner claw 2; the sleeve inner claw 2 is arranged inside the sleeve outer shell 1; the sleeve inner claw 2 is movably connected to the sleeve outer shell 1 through the first tapered thread 4 and the second tapered thread 5.

[0025] Among them, the sleeve inner claw 2 is a frustum structure with the upper base circle diameter larger than the lower base circle diameter. A central channel is opened along the central axis of the frustum structure, and the aperture of the central channel gradually decreases from top to bottom; a groove 3 is opened at the upper end of the frustum structure, and the groove 3 extends from the upper end of the frustum structure to the bottom of the frustum structure and communicates with the central channel; the aperture of the central channel gradually decreases as the tightening degree of the sleeve inner claw 2 and the sleeve outer shell 1 increases. Preferably, three grooves 3 with a fan-shaped cross-section are opened on the frustum structure, and the three grooves 3 are evenly distributed around the central axis of the frustum structure.

[0026] Specifically, after inserting the syringe into the inner claw 2 of the sleeve from the upper or lower end of the central channel, place the inner claw 2 of the sleeve in the heat-insulating sleeve. When the outer sleeve 1 and the inner claw 2 of the sleeve are continuously tightened through the first tapered thread 4 and the second tapered thread 5, the inner diameter of the end of the inner claw 2 of the sleeve with the groove 3 will continuously decrease. At this time, the frictional force between the inner wall of the inner claw 2 of the sleeve and the outer surface of the syringe will gradually increase, thereby fixing the syringe in the central channel of the inner claw 2 of the sleeve. Therefore, by changing the tightening degree between the first tapered thread 4 and the second tapered thread 5, the inner diameter of the end of the inner claw 2 of the sleeve with the slot 3 can be changed, so that the inner claw 2 of the sleeve can fix syringes of different sizes. Preferably, the taper of both the first tapered thread and the second tapered thread is between 0.5 and 2, such as 0.6, 1.0 or 1.5, and the taper of the second tapered thread is the same as that of the first tapered thread.

[0027] Furthermore, the heat-insulating sleeve is made of a metal material with good heat conduction, such as copper or aluminum; in this embodiment, the heat-insulating sleeve is made of aluminum, and a surface blackening treatment process is adopted, so that a black oxide film is formed on the surface of the aluminum material, and the black oxide film helps to increase heat radiation.

[0028] Moreover, a first magnet 6 is provided on the outer surface of the outer sleeve 1; in this embodiment, the first magnet 6 is a circular ring magnet and is respectively arranged at both ends of the outer sleeve 1; the first magnet 6 can realize the detachable connection between the outer sleeve 1 and other devices.

[0029] This embodiment also proposes a heat-insulating system, such as Figure 2 、 Figure 3 and Figure 4 as shown, the heat-insulating system includes a heat storage device 7 and the above-mentioned heat-insulating sleeve; a receiving groove capable of closely fitting with the outer wall of the outer sleeve 1 is provided on one side of the heat storage device 7; a heater 10 is provided on the other side of the heat storage device 7, and the heater 10 is inserted into the heat storage device 7 for heating the heat storage device 7; the outer sleeve 1 of the heat-insulating sleeve is detachably connected to the heat storage device 7, and both the outer sleeve 1 and the inner claw 2 of the heat-insulating sleeve have heat conductivity.

[0030] Providing a groove on the outer surface of the heat storage device 7 that can closely fit with the outer wall of the outer sleeve 1 can increase the contact area between the heat storage device 7 and the heat-insulating sleeve, improve the heat transfer efficiency between the two, and thus enable the heat-insulating sleeve to achieve a good heat-insulating effect.

[0031] Furthermore, the heat storage device 7 is large in volume and has small temperature fluctuations. By heating the heat storage device 7 with the heater 10 and transferring the heat to the heat preservation sleeve, continuous and stable heat transfer can be achieved, which is beneficial for the syringe in the heat preservation sleeve to maintain a constant temperature. The heat storage device 7 proposed in this embodiment is made of a metal material with good thermal conductivity. Preferably, such as copper or aluminum. In this embodiment, the heat storage device 7 is made of aluminum, and a surface blackening treatment process is adopted to form a black oxide film on the surface of the aluminum material, thereby increasing heat radiation.

[0032] In this embodiment, a second magnet 8 is provided at the accommodating groove of the heat storage device 7; the second magnet 8 is arranged in one-to-one correspondence with the first magnet 6 on the sleeve housing; the sleeve housing 1 is detachably connected to the heat storage device through the magnetic cooperation of the first magnet 6 and the second magnet 8. Preferably, the second magnet 8 in this embodiment is a semi-circular ring magnet.

[0033] Specifically, through the magnetic attraction between the first magnet 6 and the second magnet 8, while ensuring the detachable connection between the heat preservation sleeve and the heat storage device 7, it can also ensure the tight fit between the heat preservation sleeve and the heat storage device 7 when they are connected, thereby improving the heat transfer efficiency between the heat preservation sleeve and the heat storage device 7; and the force generated when the first magnet and the second magnet attract each other can play a positioning role, facilitating the taking and storing of the heat preservation sleeve during use.

[0034] In this embodiment, the heat preservation sleeves and the heat storage devices are arranged in one-to-one correspondence, and a heat insulation layer 9 is arranged between any two adjacent heat storage devices; the heat insulation layer 9 is arranged on the contact surface between two adjacent heat storage devices 7, which can prevent temperature interference caused by heat transfer between the two heat storage devices 7.

[0036] Specifically, the heaters 10 are evenly arranged in the heat storage device 7, and the controller can adjust the temperature of the heat storage device 7 according to the temperature data transmitted by the temperature sensor 11; when the temperature of the heat storage device 7 is lower than the required temperature, the controller turns on the heater 10 to raise the temperature of the heat storage device 7; when the temperature of the heat storage device 7 is higher than the required temperature, the controller turns off the heater 10 to lower the temperature of the heat storage device 7.

[0039] In addition, when the heat storage device is heated by heaters arranged uniformly, the temperature difference between points of the heat storage device is small, so that uniform heating of the heat preservation sleeve can be achieved. Compared with directly heating the heat preservation sleeve by heaters, heating the heat preservation sleeve through heat transfer of the heat storage device can continuously and stably control the temperature of the heat preservation sleeve within the required range, thereby ensuring the stability of the syringe temperature.
