Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments.

[0034] As described in the background art, due to the high temperature characteristic of steam, the surface temperature of a single-layer steam pipe will rise rapidly when it is used for a long time or improperly, and may reach a level sufficient to burn the skin.
[0035] In order to solve this technical problem, the utility model provides a coffee machine steam pipe.
[0036] Specifically, please refer to Figure 1-Figure 3 , the coffee machine steam pipe specifically includes:
[0037] An outer tube body 1 and an inner tube body 2 arranged inside the outer tube body 1; an insulating cavity 10 is arranged between the inner wall of the outer tube body 1 and the outer surface of the inner tube body 2, and the insulating cavity 10 is used to block the conduction and radiation of heat from the inner tube body 2 to the outer tube body 1 to achieve thermal insulation.
[0038] The coffee machine steam pipe provided by the utility model forms a double-layer steam pipe structure by arranging an outer tube body 1 on the outer surface of an inner tube body 2, and an insulating cavity 10 is arranged between the inner wall of the outer tube body 1 and the outer surface of the inner tube body 2. The insulating cavity 10 is used to block the conduction and radiation of heat from the inner tube body 2 to the outer tube body 1 to achieve heat insulation, which can effectively isolate the contact between the internal high-temperature steam and the external environment, significantly reduce the temperature of the outer layer of the utility model, and thus can reduce the situation of scalding the operator during use, thereby improving the safety of the coffee machine and enhancing the operator's experience.
[0039] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.
[0040] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.
[0041] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.
[0042] Example 1, please refer to Figure 1-Figure 3, a coffee machine steam pipe, comprising an outer tube body 1 and an inner tube body 2 arranged in the outer tube body 1; a heat insulation cavity 10 is arranged between the inner wall of the outer tube body 1 and the outer surface of the inner tube body 2, and the heat insulation cavity 10 is used to block the conduction and radiation of the heat of the inner tube body 2 to the outer tube body 1, so as to achieve heat insulation. The present application forms a double-layer steam pipe structure by arranging the outer tube body 1 on the outer surface of the inner tube body 2, and a heat insulation cavity 10 is arranged between the inner wall of the outer tube body 1 and the outer surface of the inner tube body 2, and the heat insulation cavity 10 is used to block the conduction and radiation of the heat of the inner tube body 2 to the outer tube body 1, so as to achieve heat insulation, which can effectively isolate the contact between the internal high-temperature steam and the external environment, significantly reduce the temperature of the outer layer of the present application, and thus can reduce the situation of scalding the operator during use, thereby improving the safety of the coffee machine and the user experience of the operator;
[0043] The design of the heat-insulating cavity 10 prevents the heat of the high-temperature steam in the inner tube body 2 from being directly transferred to the outer tube body 1, thereby greatly reducing heat loss and lowering the temperature of the outer layer. The lowering of the temperature of the outer layer reduces the risk of scalding the operator during use of the coffee machine, thereby improving the safety of the coffee machine.
[0044] Further, if Figure 1-Figure 3 As shown, the outer tube body 1 is composed of an outer straight tube 101 and an outer arc tube 102; the inner tube body 2 is composed of an inner straight tube 201 and an inner arc tube 202; the inner straight tube 201 is inserted into the outer straight tube 101, and the inner arc tube 202 is inserted into the outer arc tube 102, and the axis of the inner tube body 2 coincides and is concentric with the axis of the outer tube body 1, thereby ensuring the uniformity of the distance between the inner wall of the outer tube body 1 and the outer surface of the inner tube body 2, thereby reducing the situation where the temperature is too high due to the local distance being too close.
[0045] The outer arc tube 102 and the inner arc tube 202 are matched as concentric circles, which is further conducive to maintaining the uniformity of the distance between the inner wall of the outer tube body 1 and the outer surface of the inner tube body 2, thereby ensuring the consistency of the spacing between the inner wall of the outer tube body 1 and the inner tube body 2, so that the thermal insulation effect is balanced, that is, the spacing between the inner straight tube 201 and the outer straight tube 101 is consistent with the spacing between the inner arc tube 202 and the outer arc tube 102.
[0046] The outer straight tube 101 and the outer arc tube 102 are integrally formed, and the inner straight tube 201 and the inner arc tube 202 are integrally formed, and the integrity of the structure can be ensured by integrally forming.

[0049] Embodiment 3 further optimizes the coffee machine steam pipe provided in Embodiment 1. Specifically, a vacuum treatment is adopted in the heat-insulating cavity 10. Through the vacuum setting of the heat-insulating cavity 10, the conduction and radiation of heat from the inner tube body 2 to the outer tube body 1 can be effectively blocked.
[0050] Example 4, the coffee machine steam pipe provided in Example 1 is further optimized. Specifically, the inner wall of the outer tube body 1 and the outer surface of the inner tube body 2 are sprayed with a thermal insulation coating. The thermal insulation coating can be a Teflon coating. By spraying the thermal insulation coating on the inner wall of the outer tube body 1 and the outer surface of the inner tube body 2, the thermal insulation effect can be further improved.
[0051] Example 5 further optimizes the coffee machine steam pipe provided in Example 1. Specifically, the insulation cavity 10 is filled with insulation material.

The setting of the handle 803 is convenient for the operator to hold, reducing the direct contact between the user's hand and the outer tube body 1 when using it. The temperature sensor 807 can detect the temperature of the surface of the outer tube body 1 and transmit it to the controller, and the temperature is displayed by the display screen 806, so that the operator can intuitively understand the surface temperature of the outer tube body 1.
