[0034] According to one aspect of the utility model, there is provided an air duct adapter for an air-inflating heating device, Figure 1 As shown, the air duct adapter for the air heating device includes:

[0035] The air duct internal joint 10 includes a first connecting pipe 101,

[0036] The air duct external joint 20 includes a connecting portion 201,

[0037] There is a gap 30 between the first connecting tube 10 and the connecting portion 201 for inserting the air duct, and the air duct is sleeved on the first connecting tube 10 and threadedly connected to the connecting portion 201 .

[0038] Through the above technical solution, that is, through the air duct adapter for the inflation heating device provided by the utility model, on the one hand, due to the existence of the gap 30, the air duct can be clamped in the gap 30 to achieve the first fixation of the air duct and the air duct adapter; on the other hand, the air duct can be sleeved on the first connecting tube 101, so the second fixation of the air duct and the air duct adapter can be achieved, that is, the coaxiality of the air duct and the air duct adapter can be ensured; furthermore, since the air duct is threadedly connected to the connecting portion 201, the third fixation of the air duct and the air duct adapter can be achieved, that is, the axial limit and axial rotation friction are provided. Thus, the triple fixing method can ensure that the connection between the air duct and the air duct adapter is firm and the connection is stable. In addition, during the installation process, it is only necessary to insert the air duct into the gap 30, sleeve it on the first connecting tube 101 of the air duct inner joint 10, and connect the air duct outer joint 20 to the air duct by threading, which is simple to operate.

[0039] Since most of the air pipes in the prior art have external threads, Figure 2 As shown, the connecting portion 201 may be provided with an internal thread to achieve a threaded connection between the air duct and the connecting portion 201 .

[0040] In addition, in some embodiments, the gap 30 can be set to gradually decrease inward from the port close to one end of the first connecting tube 10, so that when the air duct is inserted into the gap 30, the tightening force between the air duct external joint 20 and the air duct internal joint 10 is greater.

[0041] In order to further enhance the stability of the connection between the air duct and the air duct adapter, in some embodiments, the air duct external joint 20 may further include a fixing portion 202, and the air duct internal joint 10 may further include a transition pipe 102, wherein the transition pipe 102 is disposed at an end of the first connecting pipe 101 away from the air duct, and the transition pipe 102 gradually becomes thicker in a direction extending from the end toward the distal end; wherein the fixing portion 202 is fixed on the transition pipe 102.

[0042] In this way, on the one hand, since the connecting end of the transition pipe 102 and the first connecting pipe 101 gradually becomes thicker toward the distal end (the end away from the connecting end), a gap 30 can be formed between the first connecting pipe 101 and the connecting portion 201 after the fixing portion 202 and the transition pipe 102 are fixed, so that the air duct can be arranged between the first connecting pipe 101 and the connecting portion 201, and the air duct can be limited in the axial direction; on the other hand, by fixing the fixing portion 202 and the transition pipe 102, the threaded air duct can be squeezed to a certain extent during the installation process, so that the air duct is pushed along the surface of the first connecting pipe 101 toward the transition pipe 101. 2 movement, thereby making the connection between the air duct and the first connecting pipe 101 tighter, and further enhancing the stability of the connection between the air duct and the air duct adapter; furthermore, due to the fixation of the fixing portion 202 and the transition pipe 102, the air duct outer joint 20 can be fixed on the air duct inner joint 10, so that after the air duct is fixed on the air duct inner joint 10 and the air duct outer joint 20 is fixed on the air duct inner joint 10, the air duct can be reliably clamped between the connecting portion 201 and the first connecting pipe 101, and the threaded connection between the connecting portion 201 and the air duct can be stabilized, thereby increasing the reliability of the connection between the air duct and the air duct adapter.

[0043] The present invention does not specifically limit the fixing method of the fixing portion 202 and the transition pipe 102. In some embodiments, in order to limit the relative rotation of the air duct outer joint 20 relative to the air duct inner joint 10, the fixing portion 202 can be fixed to the transition pipe 102 through a snap joint, and this method can be derived as follows: one of the fixing portion 202 and the transition pipe 102 is provided with a snap 1021, and the other is provided with a snap groove 2021 adapted to the snap 1021. Specifically, refer to Figure 2 and Figure 3 As shown, a slot 2021 may be provided on the fixing portion 202, so that a buckle 1021 matched with the slot 2021 is provided on the transition pipe 102. Of course, a buckle 1021 may also be provided on the fixing portion 202 and a slot 2021 matched with the buckle 1021 may also be provided on the transition pipe 102 (not shown in the figure), and the utility model does not make specific limitations thereto.

[0044] It should be noted that the number of buckles 1012 and slots 2021 can be set to an even number to ensure the stability of the connection. Generally, the number can be set to 4, and the 4 buckles 1012 and slots 2021 are evenly spaced.

[0045] In other embodiments, the manner in which the fixing portion 202 is fixed to the transition pipe 102 by means of a snap-fit ​​joint can also be derived into a situation in which a protrusion is provided on one of the fixing portion 202 and the transition pipe 102, and a groove is provided on the other. The specific description is similar to the description of the buckle 1021 and the slot 2021, and will not be repeated in the present utility model.

[0046] Of course, in some other embodiments, the fixing method of the fixing part 202 and the transition pipe 102 can also be designed as a threaded connection. Since the air duct external joint 20 is located outside the air duct internal joint 10, it is possible to design the fixing part 202 to be provided with an internal thread, and the transition pipe 102 to be provided with an external thread matching the internal thread, so as to realize the threaded connection.

[0047] Generally, an air duct adapter is designed because the diameters of the connecting pipe of the host and the air duct are different. Therefore, the internal joint 10 of the air duct can also be designed to include a second connecting pipe 103 connected to the host, and the diameter of the second connecting pipe 103 is different from the diameter of the first connecting pipe 101. In this case, the transition pipe 102 can be configured to have a wide side connecting end and a narrow side connecting end, the wide side connecting end is connected to the second connecting pipe 103, and the narrow side connecting end is connected to the first connecting pipe 101.

[0048] Therefore, the transition pipe 102 has a trapezoidal cross-section, which can satisfy the connection between the first connecting pipe 101 and the second connecting pipe 103 with different pipe diameters on the one hand, and on the other hand, can limit the air duct in the axial direction to prevent the air duct from moving further toward the second connecting pipe 103 during use.

[0049] In addition, in order to limit the axial movement of the air duct outer joint 20 relative to the air duct inner joint 10, a boss 104 may be provided on the transition pipe 102 or the second connecting pipe 103, and the boss 104 is provided close to the wide side connecting end to resist the fixing portion 202. Of course, those skilled in the art may also set the width of the wide side connecting end connected to the second connecting pipe 103 to resist the fixing portion 202 to prevent the air duct outer joint 20 from moving toward the second connecting pipe 103 in the axial direction.

[0050] In order to make the air duct outer joint 20 and the air duct inner joint 10 have good adaptability, optionally, reference Figure 2 As shown, the duct external joint 20 is constructed to have a tubular structure, and the tubular structure includes two ends arranged opposite to each other, wherein a fixing portion 202 is arranged near one end, and a connecting portion 201 is constructed between the fixing portion 202 and the other end.

[0051] The utility model has the following working principle:

[0052] During installation, the air duct sleeve is installed on the first connecting tube 101 of the inner joint 10 of the air duct, and the soft rubber depression on the inner side of the air duct is squeezed outward. When the air duct is installed to the limit position, the threaded structure on the outer joint 20 of the air duct is connected with the air duct thread, so that the outer joint 20 of the air duct is screwed into the air duct. When the end face of the outer joint 20 of the air duct is about to reach the position of the buckle 1021 of the inner joint 10 of the air duct, adjust the opening of the slot 2021 of the outer joint 20 of the air duct to align with the buckle 1021 of the inner joint 10 of the air duct, push the outer joint 20 of the air duct forward to the limit position, rotate and tighten, so that the buckle 1021 of the inner joint 10 of the air duct is transferred to the designated slot 2021 of the outer joint 20 of the air duct.

[0053] According to one embodiment of the utility model, an inflatable heating device is provided, which includes an air duct adapter for an inflatable heating device according to the above-mentioned method, and also includes: an inflatable heating blanket, an air duct, and a main unit, wherein one end of the air duct is fixed on the inflatable heating blanket, and the other end is connected to the main unit via the air duct adapter.

[0054] It should be understood that the utility model does not limit its application to the detailed structure and arrangement of the components proposed in the utility model. The utility model can have other embodiments and can be implemented and executed in a variety of ways. The aforementioned deformation forms and modified forms fall within the scope of the utility model. It should be understood that the utility model disclosed and defined in the utility model extends to all alternative combinations of two or more individual features mentioned or evident in the text and / or the drawings. All these different combinations constitute multiple alternative aspects of the utility model. The embodiments described in the utility model illustrate the best known methods for implementing the utility model and will enable those skilled in the art to utilize the utility model.
