Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of atomization equipment, in particular to a heating device and an atomization equipment. BACKGROUND

[0002] At present, there are many types of heating devices for electronic atomization equipment, one of which is a heating device combining hot air heating and center auxiliary heating needle heating. In the above-mentioned heating device, the air holes of the base are usually arranged around the auxiliary heating needle. When the electric heating element of the side wall of the base is electrified and heated, the heat is transferred to the auxiliary heating needle through the base, and at the same time, the hot air flow is formed in the air hole. When the aerosol generating stick is inserted into the atomization equipment, the auxiliary heating needle penetrates into the inside of the aerosol generating stick, which can directly heat the aerosol generating stick. The air hole is opposite to the bottom of the aerosol generating stick, which can form hot air heating during suction.

[0003] However, in the above-mentioned heating device, since the electric heating element is located on the outer side wall of the base, there is a certain distance between the electric heating element and the air hole and the auxiliary heating needle in the radial direction, which limits the heat transferred to the air hole and the auxiliary heating needle. In particular, the amount of heat received by the auxiliary heating needle located at the center of the base is greatly affected, and a considerable part of the heat of the electric heating element itself is lost to the outside, thereby causing uneven heating of the aerosol generating stick. The heat received by the inside of the aerosol generating stick is low, which affects the atomization efficiency, increases the energy consumption, and the user experience is not good.

DETAILED DESCRIPTION

[0043] The application will be described in further detail below with reference to the drawings. Like elements in different embodiments are denoted by like reference numerals. In the following embodiments, many details are described in order to provide a better understanding of the application. However, a person skilled in the art can easily recognize that some features can be omitted in different cases, or can be replaced by other elements, materials, methods. In some cases, some operations related to the application are not shown or described in the specification in order to avoid the core part of the application being overwhelmed by too much description, and it is not necessary to describe these related operations in detail for a person skilled in the art according to the description in the specification and general technical knowledge in the art.

[0044] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate way to form various embodiments, and the operation steps involved in each embodiment can also be sequentially adjusted or adjusted in a manner that is obvious to a person skilled in the art. Therefore, the specification and drawings are only intended to clearly describe one embodiment, and do not mean that the composition and / or order is necessary.

[0045] The serial numbers of components in this document, such as "first", "second", etc., are only used to distinguish the described objects, and do not have any sequential or technical meanings. The "connection" and "coupling" in the present application include direct and indirect connections (couplings) unless otherwise specified.

[0046] The heating device provided by the present application sets the heating element in the heating cavity of the heating base, sets the first heating column on one end of the heating base away from the outlet end, and sets a plurality of air holes in the side wall of the heating base in a circumferential direction. When the heating device is applied to the atomization equipment, the heating element can be heated, and the first heating column and the airflow in the air hole can be heated by the heating base. When the aerosol generating stick is installed in the atomization equipment, the first heating column is inserted into the inside of the aerosol generating stick in the axial direction, and can directly heat the inside of the aerosol generating stick. With the action of suction, the hot airflow in the air hole flows into the aerosol generating stick under the action of negative pressure, and forms a hot airflow heating for the aerosol generating stick. Since the heating element is located in the heating cavity and inside the air hole, it is closer to the center of the heating base. Under the same heating condition, the heating amount of the first heating column can be effectively improved, thereby improving the heating effect on the center of the aerosol generating stick, and reducing the heat loss along the lateral direction, which is beneficial to improve the heating efficiency and reduce the energy consumption.

[0047] Some embodiments of the heating device and the atomization equipment provided by the present application are described below in combination with the drawings.

[0048] In the embodiments of the first aspect of the present application, a heating device 100 is provided, as shown in Figure 1 , Figure 2 and Figure 3As shown, the heating device 100 comprises a heating base 11, a first support 12, a heating element 13, and a first heating column 14. The heating element 13 is a heat source for heating, and the heating base 11 is a heat-conducting structure. The heating base 11 has a heating cavity 111, and the heating base 11 has an opening end 112 penetrating the heating cavity 111 in a first direction; the first support 12 is arranged along the first direction, and one end of the first support 12 extends into the heating cavity 111 and is connected with the heating base 11 to support the heating base 11 during assembly; the heating element 13 is arranged in the heating cavity 111 and is arranged along the circumference of the first support 12; and the first heating column 14 is located outside the heating cavity 111 and is connected to one end of the heating base 11 away from the opening end 112. The sidewall of the heating base 11 is provided with a plurality of air holes 113, the plurality of air holes 113 are arranged at intervals around the circumference of the heating cavity 111, and each air hole 113 penetrates in the first direction. When applied to an atomization device, the heating element 13 generates heat during operation, and the heat is conducted to the first heating column 14 and the air holes 113 through the heating base 11, so as to raise the temperature of the airflow in the first heating column 14 and the air holes 113, thereby heating the aerosol generating stick loaded in the atomization device.

[0049] When the aerosol generating stick 25 is loaded in the atomization device, as an example in Figure 4 , the first heating column 14 can be inserted into the inside of the aerosol generating stick 25 along the first direction, and the air holes 113 are opposite to the end face of the aerosol generating stick 25, so as to heat the inside of the aerosol generating stick 25 through the first heating column 14 on the one hand, and to form hot airflow heating of the aerosol generating stick 25 through the hot airflow of the air holes 113 when the airflow moves due to the suction action on the other hand. In actual application, the aerosol generating stick 25 can be continuously heated by the first heating column 14, which can be used as a preheating process, and the hot airflow moves correspondingly due to the suction action to intermittently heat the aerosol generating stick 25, which can be used as a strengthening heating process.

[0050] It should be noted that the positions of the first heating column 14 and the air holes 113 can be reasonably arranged according to assembly requirements, so that the first heating column 14 is located at or close to the central position of the aerosol generating stick 25 to form central heating; at the same time, the positions of the air holes 113 can be reasonably arranged so that the hot airflow of the air holes 113 is relatively uniformly convected to the aerosol generating stick 25. In addition, different materials with different heat conduction properties can be selected in actual application, for example, the heating base 11 and the first heating column 14 can be made of high-thermal-conductivity materials such as metal materials, specifically, the heating base 11 can be made of aluminum alloy, copper, etc., and the first heating column 14 can be made of aluminum alloy, copper, alumina, etc.; and the first support 12 can be made of low-thermal-conductivity materials such as ceramics and glass.

[0051] It can be understood that the heating device in the existing atomization equipment usually adopts a side heating mode, that is, the heating element is located on the side wall of the heating base, and the auxiliary heating needle (that is, a specific form of the first heating column) is usually located at the center of the heating base. Due to the certain distance in the lateral direction, the heat conduction distance of the heating element to the auxiliary heating needle is relatively large, which causes the heating amount of the auxiliary heating needle to be relatively small under the same heating condition, thereby affecting the heating effect of the central part of the aerosol generating stick. In addition, the lateral heat loss of the heating element itself is relatively large, resulting in low overall heating efficiency and high energy consumption.

[0052] The heating device in the embodiment can improve the heating effect of the central part of the aerosol generating stick, improve the heating and atomization efficiency, and improve the problem of uneven heating of the aerosol generating stick. In addition, the heating device can effectively reduce the heat loss of the heating element and reduce the energy consumption. The heating device of the present application can effectively adapt to the atomization equipment for heating the aerosol generating stick and effectively improve the user experience.

[0053] In further embodiments of the present application, as shown in Figure 3 、 Figure 5 and Figure 6 , the heating element 13 is connected to the circumferential outer side of the first support 12 to support the heating element 13 through the first support 12. The heating element 13 is an electric heating heating element, and the heating element 13 has a pin structure 131 extending out of the heating cavity 111. When the heating device 100 is applied to the atomization equipment, the pin is electrically connected to the power supply device 23 to form an electrical connection, so that the heating element 13 is powered by the power supply device 23 to heat, so that the heating device 100 realizes the heating of the aerosol generating stick. Wherein, the heating element 13 can be directly connected with the outer side wall of the first support 12, or a gap can be provided between the heating element 13 and the outer side wall of the first support 12.

[0054] Further, in a specific implementation, as shown in Figure 3 、 Figure 5 and Figure 6 , the heating cavity 111 of the heating base 11 is filled with a fixing glue 15 to bond and fix the heating element 13 and the first support 12 through the fixing glue 15, and the first support 12 and the heating base 11 are also bonded and fixed through the fixing glue 15. Wherein, the fixing glue 15 can be ceramic glue. By using the gluing method, the connection and fixation between the heating element 13, the first support 12 and the heating base 11 can be realized at the same time, which is simple in structure and easy to realize.

[0055] Further, in another specific implementation, as shown in Figure 7In the example shown in FIGS. 1, 2, and 3, the first support 12 is connected with the heating base 11 by screwing. Specifically, the outer side wall of the portion of the first support 12 extending into the heating cavity 111 has a first threaded portion 121, and the inner side wall of the heating cavity 111 has a second threaded portion 114 corresponding to the first threaded portion 121. The first threaded portion 121 cooperates with the second threaded portion 114 to form a threaded connection, so that the first support 12 is fixedly connected with the heating base 11. The heating element 13 can be connected with the first support 12 by any suitable connection method, such as gluing or clamping, as needed. In the first direction, the heating element 13 is spaced apart from the first threaded portion 121 to avoid interference.

[0056] In further embodiments of the present application, as shown in Figure 8 、 Figure 9 and Figure 10 , a second heating column 115 is arranged in the heating cavity 111 of the heating base 11. The second heating column 115 extends in the first direction and is fixedly connected with the heating base 11. The first support 12 is arranged corresponding to the second heating column 115, and the end of the first support 12 extending into the heating cavity 111 is connected with the second heating column 115 to form a fixed connection with the heating base 11 through the second heating column 115. At this time, the heating cavity 111 is the space outside the second heating column 115 in the circumferential direction, and the heating element 13 is connected to the outside of the second heating column 115 in the circumferential direction, so that heat generated by the heating element 13 is conducted through the second heating column 115 and the heating base 11. The heating element 13 is an electric heating element 13, which has a pin structure 131 extending out of the heating cavity 111. When the heating element 13 is applied to an atomization device, the pin structure 131 is electrically connected with a power supply device 23 to enable the heating element 13 to generate heat by being powered by the power supply device 23. Specifically, the heating element 13 can be directly connected with the outer side wall of the second heating column 115, or a gap can be provided between the heating element 13 and the outer side wall of the second heating column 115. In this embodiment, the first support 12 is separate from the heating element 13 to facilitate assembly and connection.

[0057] Further, as shown in Figure 10 、 Figure 11 and Figure 12 , the heating cavity 111 is filled with a fixing glue 15, and the heating element 13 is fixedly connected with the second heating column 115 by the fixing glue 15. The second heating column 115 is arranged corresponding to the first heating column 14, so that the heating element 13 is close to the first heating column 14. The second heating column 115 has a connecting hole 1151 arranged in the first direction, and the end of the first support 12 extending into the heating cavity 111 extends into the connecting hole 1151 and is connected with the second heating column 115.

[0058] The first support member 12 and the second heating column 115 can be connected in different ways. For example, in one specific implementation, the first support member 12 and the inner wall of the connection hole 1151 are interference-fitted to connect and fix the first support member 12 and the second heating column 115; in another specific implementation, the connection hole 1151 is filled with a fixing glue 15 to bond and fix the first support member 12 and the second heating column 115. The adhesive method is simple in structure and easy to process and shape; in another specific implementation, Figure 10 In the example, the connecting hole 1151 is set as a first threaded hole 1152, and the outer wall of the part of the first support member 12 extending into the connecting hole 1151 has a third threaded portion 122. A threaded fit is formed between the third threaded portion 122 and the first threaded hole 1152 to achieve the connection and fixation between the first support member 12 and the second heating column 115. The threaded connection is easy to disassemble and convenient to assemble.

[0059] It should be noted that the fixing glue 15 can specifically be ceramic glue; depending on the usage location and requirements, fixing glue 15 with different thermal conductivity can be used. For example, the fixing glue 15 used to bond the heating element 13 can use a glue with better thermal conductivity, while the fixing glue 15 used to fix the first support member 12 can use a glue with poor thermal conductivity.

[0060] In a further embodiment of the present application, Figure 10 In the example shown in FIG. 1 , in the first direction, the first heating column 14 has a spike portion 141 at one end away from the heating base 11, forming a needle-like structure. This facilitates insertion into the aerosol generating stick when in contact with the aerosol generating stick. The specific dimensions of the first heating column 14 can be adjusted based on the dimensions of the aerosol generating stick to meet assembly and heating requirements.

[0061] There are many different ways of connecting the first heating column 14 and the heating base 11. For example, in one specific implementation, Figure 13 In the example, the first heating column 14 and the heating base 11 are an integrally formed structure, that is, after the processing is completed, the first heating column 14 and the heating base 11 are an integral structure, and no subsequent connection and assembly are required; in another specific implementation, such as Figure 10As shown, a first through hole 116 is formed on the end of the heating substrate 11 away from the open end 112, and the first through hole 116 is communicated with the heating chamber 111. The first heating column 14 extends into the heating chamber 111 through the first through hole 116, and the end of the first heating column 14 away from the spike portion 141 abuts against the first support member 12, and a radial protrusion structure 142 is provided on the side wall of the portion of the first heating column 14 located in the heating chamber 111, and the radial protrusion structure 142 abuts against the inner wall surface of the heating chamber 111 in the first direction, so that the first heating column 14 is connected and fixed to the heating substrate 11 through the first support member 12 and the radial protrusion structure 142; in another specific implementation, as Figure 14 In the example, a second threaded hole 117 is formed on the end of the heating chamber 111 away from the open end 112. Correspondingly, a fourth threaded portion 143 is formed on the outer wall of the end of the first heating column 14 away from the spike portion 141. The fourth threaded portion 143 forms a threaded connection with the second threaded hole 117, so that the first heating column 14 is connected and fixed to the heating base 11. The second threaded hole 117 can be a through hole or a blind hole. In the second and third connection methods described above, the first heating column 14 and the heating base 11 are both split structures, which helps to reduce the difficulty of processing individual parts. Moreover, when conditions permit, they can be detachable and can be replaced separately.

[0062] In a further embodiment of the present application, Figures 1 to 4 As shown, the heating base 11 specifically adopts a cylindrical structure. Accordingly, the heating cavity 111 also adopts a cylindrical cavity. The heating cavity 111 is arranged coaxially with the heating base 11, and the first heating column 14 and the first support member 12 are also arranged coaxially with the heating base 11. That is, the first heating column 14 and the first support member 12 are both located at the center of the heating base 11 and the heating cavity 111. When the first heating column 14 is inserted into the aerosol generating rod 25, it can be located at or close to the center of the aerosol generating rod 25. At the same time, the heating element 13 can be closer to the center of the heating cavity 111, thereby improving the heating effect of the first heating column 14. In particular, around the circumference of the heating base 11, a plurality of air holes 113 are arranged in an annular array with the axis of the heating base 11 as the central axis. This allows the plurality of air holes 113 to be evenly distributed around the circumference, thereby making the temperature of the hot air flow in the air holes 113 relatively uniform. It should be noted that, depending on the specific size settings, the multiple air holes 113 can be arranged as one or more groups of rings around the central axis. When arranged as multiple groups of rings, such as Figure 2 In the example, different groups of pores 113 form concentric circles with each other. Furthermore, different groups of pores 113 can also be staggered to improve space utilization and increase the number of pores 113.

[0063] An atomization device 200 is provided in the embodiments of the second aspect of the present application, as shown in Figure 4 、 Figure 15 、 Figure 16 and Figure 17 , the atomization device 200 comprises a housing 21, the heating device 100 in any of the above embodiments, and a power supply device 23.
