[0034] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various embodiments, and the operation steps involved in each embodiment can be sequentially adjusted or modified in a manner that can be apparent to those skilled in the art. Therefore, the specification and drawings are only intended to clearly describe one embodiment, and do not mean the necessary composition and / or order.

[0035] The serial numbers of components in this paper, such as "first", "second", etc., are only used to distinguish the described objects, and do not have any order or technical meaning. The "connection" and "coupling" in this application include direct and indirect connection (coupling) unless otherwise specified.

[0036] In the related art, the atomization device using the side wall hot gas flow type heating body uses aerogel or vacuum tube for heat insulation, but the aerogel itself can store heat, and continuous use cannot reduce power consumption, and the vacuum tube has high cost and occupies a large space.

[0037] In view of this, the embodiments of the application provide an atomization device and an atomization equipment comprising the atomization device, to solve the technical problems of poor heat insulation effect, high cost and large space occupation of the existing atomization device.

[0038] Please refer to Figure 1 and Figure 2 The embodiments of the application provide an atomization equipment 100, comprising an atomization device 101, a shell 102 and a power supply assembly 103, the atomization device 101 and the power supply assembly 103 are arranged in the shell 102, the power supply assembly 103 is used for supplying power to the atomization device 101, an aerosol product 200 is placed in the atomization device 101, and the atomization device 101 is powered on to heat the aerosol product 200 to generate an aerosol.

[0039] Please refer to Figure 2 and Figure 3The atomization device 101 comprises a mounting base 10, a heating body 20 and a reflective heat insulation layer 30. The heating body 20 is arranged in the mounting base 10, and the reflective heat insulation layer 30 is arranged between the heating body 20 and the mounting base 10 and surrounds the outer surface of the heating body 20. The power supply assembly 103 supplies power to the heating body 20.

[0040] Referring to Figure 4 and Figure 6 , the heating body 20 has a hollow cylindrical structure, comprising a containing cavity 211 and an opening 212 communicating with the containing cavity 211. The opening 212 is located at one end of the heating body 20, and the containing cavity 211 extends away from the opening 212. The containing cavity 211 is used for containing the aerosol product 200, and the opening 212 is used for inserting the aerosol product 200 into the containing cavity 211. That is, the heating body 20 has an opening 212 at one end and is closed at the other end. The aerosol product 200 is inserted into the heating body 20 through the opening 212 and is contained in the containing cavity 211. The heating body 20 can heat the aerosol product 200 contained in the containing cavity 211 to generate an aerosol.

[0041] Referring to Figure 4 and Figure 6 , the inner wall of the heating body 20 is provided with a flow guide groove 213 communicating with the opening 212. The opening 212 is also used for introducing external gas into the flow guide groove 213. The flow guide groove 213 is used for guiding the gas from the opening 212 to the end of the containing cavity 211 away from the opening 212. By arranging the flow guide groove 213, the gas can flow to the end of the containing cavity 211 away from the opening 212, i.e. to the end of the aerosol product 200, and then flow into the aerosol product 200. When the gas flows through the flow guide groove 213, it can be heated by the heating body 20 to become a hot gas flow, so that the gas flow flowing into the aerosol product 200 is a hot gas flow, thereby achieving heating of the aerosol product 200.

[0042] By arranging the reflective heat insulation layer 30 between the mounting base 10 and the heating body 20 and surrounding the outer surface of the heating body 20, the reflective heat insulation layer 30 can reflect the heat radiation of the heating body 20 after the heating body 20 is powered and heated, thereby preventing the heat generated by the heating body 20 from being conducted to the mounting base 10. The reflective heat insulation layer 30 does not store heat itself, has good heat insulation effect, and has low cost and small space occupation. Therefore, the atomization device 101 provided by the embodiment has good heat insulation effect, low cost and small space occupation.

[0043] In an embodiment, referring to Figure 2 , Figure 6 and Figure 7The heating body 20 comprises a heating body base 21 and a heating wire 22. The heating body base 21 is in a hollow cylindrical structure, and is provided with a receiving cavity 211, an opening 212 and a flow guide groove 213. The heating wire 22 is arranged at the bottom and / or the side of the heating body base 21, and the power supply assembly 103 supplies power to the heating wire 22. Specifically, one end of the heating body base 21 is provided with the opening 212, and the other end of the heating body base 21 away from the opening 212 is closed. The end of the heating body base 21 provided with the opening 212 is the top of the heating body base 21, and the other end of the heating body base 21 away from the opening 212 is the bottom of the heating body base 21. In this embodiment, the heating wire 22 is arranged at the bottom of the heating body base 21, i.e. at the other end of the heating body base 21 away from the opening 212. The flow guide groove 213 is arranged at the inner side of the heating body base 21, and is communicated with the opening 212 and the other end of the heating body base 21 away from the opening 212. When the aerosol product 200 is inserted into the receiving cavity 211 through the opening 212, the end of the aerosol product 200 extends into the other end of the heating body base 21 away from the opening 212, i.e. the bottom of the heating body base 21.

[0044] By arranging the heating wire 22 at the bottom of the heating body base 21, the heat generated by the heating wire 22 after being powered can quickly heat the area, so that the gas at the end of the aerosol product 200 can be heated first, and the aerosol product 200 can be quickly heated. At the same time, the heat at the bottom of the heating body base 21 can be transferred to the side, so that the gas in the flow guide groove 213 can be preheated before flowing to the bottom of the heating body base 21. In addition, by arranging the heating wire 22 at the bottom of the heating body base 21, the generated heat can be effectively utilized, and the heat energy loss of the heating body 20 is reduced.

[0045] In an embodiment, the heating body base 21 can be made of high thermal conductivity materials, such as aluminum alloy, copper, aluminum oxide, ceramic, etc. By using high thermal conductivity materials to prepare the heating body base 21, the thermal conductivity of the heating body base 21 is improved, so that the heat generated by the heating wire 22 can be transmitted into the receiving cavity 211 as much as possible, so as to reduce the heat energy loss.

[0046] Please refer to Figure 5 and Figure 6The heating body 20 further comprises a limiting member 23 arranged at the bottom of the heating body base 21 and located at the side of the heating body base 21 facing the accommodating cavity 211. The limiting member 23 is used to abut against the end of the aerosol product 200 when the aerosol product 200 is inserted into the accommodating cavity 211, so that a gap 24 is formed between the end of the aerosol product 200 and the heating body base 21. The flow guide groove 213 is in communication with the gap 24 at the end away from the opening 212, and the flow guide groove 213 can guide the airflow from the opening 212 to the gap 24. In this way, the opening 212, the flow guide groove 213 and the gap 24 form an airflow channel. The airflow from the outside of the heating body 20 passes through the opening 212 and the flow guide groove 213 in sequence to the gap 24, and then enters the aerosol product 200 through the gap 24. In particular, when the airflow passes through the flow guide groove 213 and the gap 24, the heating body base 21 can heat the airflow passing through it, so that the cold airflow is heated to become a hot airflow, that is, the airflow entering the aerosol product 200 is a hot airflow, thereby heating the aerosol product 200.

[0047] Please refer to Figure 4 The mounting base 10 comprises a sleeve 11 and a base 12. The base 12 is sealingly connected to one end of the sleeve 11, and forms a containing space 13 together with the sleeve 11.

The sleeve 11 is sleeved on the periphery of the heating body 20, and the opening 212 of the heating body 20 is arranged away from the base 12, that is, the opening 212 of the heating body 20 is arranged towards the opening 14 and corresponds to the opening 14. The aerosol product 200 can be inserted into the accommodating cavity 211 through the opening 14 and the opening 212 in sequence.

Specifically, the connecting assembly 40 is connected between the inner wall of the sleeve 11 and the end of the heating body base 21 provided with the opening 212. In this way, on the one hand, the contact area between the heating body base 21 and the mounting base 10 is small, which can reduce heat loss; on the other hand, the heating body base 21 and the mounting base 10 have the gap 50 therebetween, and the gas is located in the gap 50. Since the heat conduction performance of the gas is poor, heat loss can be further reduced.

[0049] In an embodiment, the gap 50 has a width greater than or equal to 0.3 mm. In practice, the gap 50 can have a width of 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, 0.5 mm, etc.
