[0051] The utility model embodiment provides an airbag structure, such as Figures 1 to 3 As shown, the airbag structure includes an airbag housing 1, airbag silica gel 2, a side cover plate 3, a heating component 4 and a control component 5.

[0052] The airbag housing 1 is a barrel-shaped structure. The airbag silica gel 2 is a hollow columnar structure, which is located inside the airbag housing 1 and forms an airbag cavity 13 with a variable volume with the inner wall of the airbag housing 1 .

[0053] The hollow portion 24 of the airbag silica gel 2 and the shell bottom of the airbag shell 1 form a milk bottle accommodating cavity 20 for accommodating a milk bottle 8. The milk bottle 8 can be placed in the milk bottle accommodating cavity 20 for heating.

[0054] The side cover plate 3 is arranged on the airbag housing 1, and is provided with a conductive column 31 and an airbag opening 30 communicating with the airbag cavity 13. The heating component 4 is arranged on the airbag silicone 2 and is electrically connected to the conductive column 31. The control component 5 includes a power board 51 and an air pump 52.

[0055] The air inlet and the air outlet of the air pump 52 are connected to the air bag port 30 through the air path component (7) respectively. The volume of the air bag cavity 13 can be increased by inflating the air bag cavity 13, so that the air bag silicone 2 and the heating component 4 thereon are in contact with the milk bottle 8, and then the milk bottle 8 is heated by the heating component 4 on the air bag silicone 2. Fig.10 shown.

[0056] And, by sucking air into the airbag cavity 13 to reduce the volume in the airbag cavity 13, the airbag silica gel 2 and the heating component 4 thereon are separated from the milk bottle 8. Fig. 9 Then it is convenient to take out the feeding bottle 8.

[0057] The power board 51 is electrically connected to the heating component 4, the control board 53 of the air pump 52 and the conductive column 31 respectively, and the power board 51 can respectively supply power to the conductive column 31 and the air pump 52.

[0058] The hollow part 24 of the airbag silica gel 2 in the airbag structure provided in this embodiment and the shell bottom of the airbag shell 1 form a bottle accommodating cavity 20 for placing the milk bottle 8. The airbag cavity 13 can be inflated so that the airbag silica gel 2 fits the milk bottle 8, and the heat is transferred to the milk bottle 8 through the heating component 4 for heating. The airbag structure of this embodiment can achieve waterless milk heating without a water bath, with higher heat transfer efficiency and shortened milk heating time. And the deformation of the airbag can fit and heat milk bottles 8 of different shapes, which greatly facilitates the use of users.

[0059] like Figure 2 and Figure 3 As shown, in some embodiments, the airbag housing 1 includes three major parts: an airbag outer shell 10 , an airbag upper cover 11 and an airbag bottom cover 12 .

[0060] The airbag shell 10 is a columnar body with both ends open. The airbag silica gel 2 is arranged in the airbag shell 10 and forms an airbag cavity 13 together with the airbag shell 10 .

[0061] The airbag bottom cover 12 is used to block the bottom open end of the airbag shell 10 and the bottom open end of the airbag silicone 2, and to seal the bottom end of the airbag silicone 2 and the bottom end of the airbag shell 10. The airbag bottom cover 12 forms the shell bottom of the airbag shell 1 to support the milk bottle 8 placed in the milk bottle accommodating cavity 20.

[0062] The airbag upper cover 11 is an annular body, which is connected to the top open end of the airbag shell 10 and makes the top end of the airbag silica gel 2 and the top end of the airbag shell 10 sealed and connected.

[0063] In order to ensure the sealing between the airbag silica gel 2 and the airbag shell 10. Figures 2 to 4 As shown, in some embodiments, the bottom and top ends of the airbag silicone 2 are respectively provided with flange portions 23, the top end of the airbag shell 10 is provided with an annular platform 14 for supporting the flange portion 23 at the top end of the airbag silicone 2, and the airbag bottom cover 12 is provided with an annular platform 14 for supporting the flange portion 23 at the bottom end of the airbag silicone 2.

[0064] Furthermore, the airbag upper cover 11 is connected to the annular platform 14 on the airbag shell 10 to squeeze the flange 23 at the top of the airbag silicone 2 and the annular platform 14 on the airbag shell 10 together, thereby ensuring the tightness of the connection between the two. The annular platform 14 on the airbag bottom cover 12 is connected to the bottom of the airbag shell 10 to squeeze the flange 23 at the bottom of the airbag silicone 2 and the annular platform 14 on the airbag bottom cover 12 together, thereby ensuring the tightness of the connection between the two.

[0065] In some embodiments, the airbag structure further includes a first temperature detection member 6 disposed on the airbag housing 10. The first temperature detection member 6 is preferably an NTC thermistor, which is also called a negative temperature coefficient thermistor. It is a type of sensor resistor whose resistance value decreases as the temperature increases. It is widely used in various electronic components, such as temperature sensors, resettable fuses, and automatically adjustable heaters. The first temperature detection member 6 is also connected to the power board 51.

[0066] Preferably, the first temperature detecting member 6 of this embodiment can be fixed on the airbag bottom cover 12 . When the milk bottle 8 is placed in the milk bottle accommodating cavity 20 , the first temperature detecting member 6 can contact the bottom of the milk bottle 8 , thereby being used to detect the temperature of the milk in the milk bottle 8 .

[0067] In addition, the first temperature detection element 6 is also electrically connected to the control board 53. When the first temperature detection element 6 detects that the temperature of the milk in the milk bottle 8 exceeds a preset value, it sends a heating stop signal to the control board 53. After receiving the heating stop signal, the control board 53 turns off the air pump 52 and the heating component 4. Figure 1 As shown, in some embodiments, the airbag structure further includes an air circuit assembly 7 , and the air circuit assembly 7 includes an airway body 72 , an air intake solenoid valve 73 and an air intake solenoid valve 74 .

[0068] like Figure 2 and Figure 3 As shown, in some embodiments, the airbag structure further includes a second temperature detection member 60 disposed on the airbag silicone 2. The second temperature detection member 60 is located in the airbag cavity 13 and attached to the airbag silicone 2 to detect the temperature of the airbag silicone 2. The second temperature detection member 60 is preferably an NTC thermistor.

[0069] The second temperature detection component 60 is electrically connected to the power board 51 through the conductive column 31 on the side cover plate 3. The chip on the power board 51 is in communication connection with the second temperature detection component 60. When the second temperature detection component 60 detects that the temperature of the airbag silicone 2 exceeds a preset value, the power board 51 will disconnect the power supply to the heating component 4 to prevent high temperature from being generated when there is little milk in the bottle 8 and dry burning when there is no milk.

[0070] The first temperature detection member 6 and the second temperature detection member 60 of the present embodiment can be respectively connected to the conductive pillars 31 to achieve electrical connection with the power board 51 .

[0071] An air intake path and an air suction path are provided in the airway body 72. The air intake path and the air suction path are connected to the air bag opening 30 on the side cover plate 3 through the air bag pipeline 71 respectively.

[0072] The air intake path is connected to the air outlet of the air pump 52 through the air intake pipeline 75 , and the air suction path is connected to the air intake of the air pump 52 through the air suction pipeline 76 .

[0073] The air intake solenoid valve 73 is used to control the on-off of the air intake path, and the air intake solenoid valve 74 is used to control the on-off of the air intake path.

[0074] The air intake solenoid valve 73 and the air suction solenoid valve 74 can be controlled by the control board 53. When the airbag cavity 13 is to be inhaled, the air suction solenoid valve 74 on the airway body 72 is controlled to open the air suction path and the air intake solenoid valve 73 is controlled to close the air intake path, and then the airbag cavity 13 is inhaled through the air pump 52; when the airbag cavity 13 is to be inflated, the air intake solenoid valve 73 on the airway body 72 is controlled to open the air suction path and the air suction solenoid valve 74 is controlled to close the air suction path, and then the airbag cavity 13 is inflated through the air pump 52.

[0075] In this embodiment, the air circuit assembly 7 and the power board 51 are respectively fixed on the airbag bottom cover 12, thereby reducing the radial space of the entire airbag structure.

[0076] like Figure 4 and Figure 5 As shown, in some embodiments, the airbag silicone 2 is provided with folds. When the airbag cavity 13 is filled with gas, the folds on the airbag silicone 2 will be stretched open, thereby ensuring that the airbag silicone 2 can better fit the feeding bottle 8.

[0077] The folds on the airbag silicone 2 of this embodiment include annular radial folds 21 and axial folds 22 extending along the axial direction of the airbag silicone 2. The radial folds 21 are mainly used to increase the overall height of the airbag silicone 2 after it is expanded. The axial folds 22 are used to increase the inner diameter of the airbag silicone 2 after it is expanded. The radial folds 21 and the axial folds 22 can ensure that the airbag silicone 2 can match different feeding bottles 8.

[0078] like Figure 4 As shown, in some embodiments, the radial folds 21 on the airbag silicone 2 are mainly located at the two ends of the airbag silicone 2, and there are multiple radial folds 21 at each end, and they are arranged at intervals in the axial direction of the airbag silicone 2. The axial folds 22 are located between the radial folds 21 at the two ends, and there are also multiple axial folds 22. The multiple axial folds 22 are arranged at intervals along the circumference of the airbag silicone 2.

[0080] Furthermore, the airbag housing 10 is provided with a mounting opening corresponding to the side cover plate 3. The side cover plate 3 can be fixed to the airbag housing 10 by bolts and seal the mounting opening. A sealing ring 32 is provided between the side cover plate 3 and the airbag housing 10 to ensure the tightness of the connection between the side cover plate 3 and the airbag housing 10.

[0081] like Figure 3 and Figure 6 As shown, in some embodiments, the heating component 4 includes a plurality of flexible heating films 40 pasted on the airbag silicone 2. The plurality of flexible heating films 40 are electrically connected to the power board 51 through the conductive column 31. Among them, the flexible heating film 40 can be selected from PI heating film or carbon heating film. The flexible heating film 40 can generate heat after being powered on. The flexible heating film 40 can fit well with the milk bottle 8 so that the heat can be quickly transferred to the milk bottle 8, and the heat generated by the flexible heating film 40 is directly transferred to the milk bottle 8 through the silicone without the need for other intermediate media, thereby achieving the purpose of preventing the milk bottle 8 from getting wet and quickly warming the milk.

[0082] In some embodiments, the multiple flexible heating films 40 can be divided into multiple groups, each group can include at least three flexible heating films 40, and the three flexible heating films 40 are connected in series through leads. After two adjacent groups are connected in parallel, they are electrically connected to the power board 51 through conductive columns 31, thereby ensuring that when one of the groups fails, the bottle 8 can still be heated.

[0083] Preferably, the number of the flexible heating films 40 in this embodiment is 6, which are respectively attached to the inner wall of the airbag silicone 2, and the heat generated by the flexible heating films 40 can be transferred to the feeding bottle 8 through the airbag silicone 2. Of course, the number of the flexible heating films 40 of the utility model is not limited to 6 in this embodiment, and the number of the flexible heating films 40 can be determined according to the specific situation and grouped accordingly.

[0084] In some embodiments, the flexible heating film 40 is rectangular in shape. A plurality of rectangular flexible heating films 40 are arranged around the airbag silicone 2 at intervals to ensure that the milk bottle 8 is heated evenly.
