[0027] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0028] The various specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction, for example, different embodiments and technical solutions can be formed by combining different specific technical features. In order to avoid unnecessary repetition, the various possible combinations of the specific technical features in the utility model will not be described separately.
[0029] In the following description, the terms "first\second\..." are only used to distinguish different objects, and do not mean that the objects have the same or related points. It should be understood that the directions "above", "below", "outside" and "inside" are all directions in normal use, and the directions "left" and "right" refer to the left and right directions shown in the corresponding schematic diagrams, which may or may not be the left and right directions in normal use.
[0030] It should be noted that the terms "comprises", "includes" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element. "Multiple" means greater than or equal to two.
[0031] The embodiment of the utility model provides a heating device, which can be applied to an electronic atomization device, and the electronic atomization device can be used to atomize an aerosol generating matrix into a gaseous aerosol. The electronic atomization device can be applied to various atomization scenarios. For example, the electronic atomization device can be applied to atomization scenarios such as medical cosmetology, nicotine delivery, and daily life. The aerosol generating matrix can be a powder, a fragrance, a nicotine preparation, and an aerosol matrix that can produce a special smell. Those skilled in the art can understand that there can be many application scenarios for the electronic atomization device. The embodiment of the utility model does not limit the application scenario of the electronic atomization device, and the application scenario of the electronic atomization device will not limit the structure of the heating device.
[0032] The heating device and the electronic atomization device in the embodiments of the utility model are applied to the field of heat-not-burn (HNB) atomization.
[0033] Reference Figure 1 and Figure 2 As shown, the electronic atomization device in the related art is described below: The related aerosol generating system includes an electronic atomization device 4 and an aerosol generating substrate 2 (smoke cartridge). The electronic atomization device 4 includes a housing 41 and a heating body 42 accommodated in the housing, and a receiving space 420 is provided in the heating body 42, and the receiving space 420 is used for inserting the aerosol generating substrate 2. In some embodiments, the heating body 42 is composed of a receiving tube and a heating element arranged on the surface of the receiving tube, and the receiving tube is formed with a receiving space 420.
[0034] The two ends of the heating body 42 of the relevant HNB device require support members to support the heating body 42. For example, the support member can be a bracket. Usually, the support member is made of high-temperature resistant material, such as high-temperature resistant plastic. First of all, in order to prevent the leakage of the aerosol-generating matrix 2 during the heating process, the relevant HNB device is provided with a seal at the connection between the heating body 42 and the bracket 43. The setting of the seal is not only troublesome to assemble, but also increases the manufacturing cost. In addition, the setting of the seal is easy to deform at high temperature, resulting in a loose seal, so that the harmful aerosols generated by other components connected to the bracket 43 and / or the heating body 42 at high temperature pass through the loose seal and enter the heating body 42 and are inhaled by the user, causing harm to the user's body.
[0035] like Figure 2 As shown, the upper and lower ends of the heating body 42 in the relevant heating device are connected to the plastic bracket 43. Generally, the upper and lower ends of the heating body 42 are sealed with glue or silicone at the connection with the plastic bracket 43 to prevent the escape of the aerosol matrix. The glue and silicone are both marked with Q in the figure. Taking glue sealing as an example, the main component of the glue is a single-component or two-component resin, and the other components are relatively complex. The glue is mostly volatile or has high-temperature failure properties. When the glue evaporates, it will produce gases that are harmful to human health, posing a great safety hazard. Taking silicone sealing as an example, the high-temperature resistance of silicone is limited. When the heating device is used at a temperature higher than 320°C or is used at high temperatures for a long time, the sealing performance of silicone decreases, which is not conducive to the long-term use of the heating device.
[0036] The heating device provided in the embodiment of the utility model is used to solve the above-mentioned technical problems. The heating device provided by the utility model is described in detail below.
[0037] like Figure 3 and Figure 4 As shown, the heating device 1 comprises a heating component 11, a first fixing base 12, a second fixing base 13 and a sealing member 14. The heating component 11 can generate high temperature, so the aerosol generating substrate 2 that contacts or approaches the heating component 11 can be atomized. Figure 5 and Figure 6 As shown, the interior of the heating assembly 11 is provided with a heating chamber 110 that penetrates in a first direction, and the heating chamber 110 is used to accommodate an aerosol generating substrate, and the aerosol generating substrate 2 built into the heating chamber 110 can be atomized into an aerosol. The aerosol formed after atomization is in the heating chamber 110, and under the suction action of the user, it leaves the heating chamber 110 and enters the user's oral cavity. The first direction is represented by a dotted line a in the figure.
[0038] like Figure 4 and Figure 6As shown, since the heating chamber 110 is through in the first direction, the heating chamber 110 has a first opening 1101 and a second opening 1102 in the first direction; the first opening 1101 is an opening for the aerosol generating substrate 2 to pass through. The heating assembly 11 forming the heating chamber 110 has a first end 111 and a second end 112 opposite to each other in the first direction, the first opening 1101 is arranged at the first end 111, and the second opening 1102 is arranged at the second end.
[0039] like Figure 4 and Figure 5 As shown, the first fixing seat 12 abuts against the first end 111 of the heating component 11, and the second fixing seat 13 abuts against the second end 112 of the heating component 11; the abutment can be understood as the first fixing seat or the second fixing seat being in close contact with the heating component. Exemplarily, the first fixing seat 12 abuts against the first end 111 tightly, and the second fixing seat 13 abuts against the second end 112 tightly, so that there is no gap at the abutment.
[0040] like Figure 4 and Figure 5 As shown, since the first fixing seat 12 abuts against the first end 111 of the heating component 11, and the second fixing seat 13 abuts against the second end 112 of the heating component 11; the first end 111 of the heating component 11 is fixed or positioned by the first fixing seat 12, and the second end 112 of the heating component 11 is fixed or positioned by the second fixing seat 13. These two fixing seats can be made of high-temperature resistant plastic, and the two fixing seats can also play a role in isolating the high temperature of the heating component. It can be understood that the heating component has a high temperature due to the heat generation, and is therefore not suitable for connection with other components; while the temperatures of the two fixing seats are relatively low, so that they can be connected with other components, and therefore, the two fixing seats can also play a connecting role. The first fixing seat 12 is provided with a first through hole 120 that passes through in the first direction, and the first through hole 120 is connected to the first opening 1101. As shown Figure 6 As shown, the first through hole 120 is for the aerosol generating substrate 2 to pass through; thus, the aerosol generating substrate passes through the first through hole 120 and the first opening 1101 in sequence and enters the heating chamber 110. The second fixing seat 13 blocks the second opening 1102 of the heating chamber to reduce the leakage of the aerosol in the heating chamber 110.
[0041] like Figure 5As shown, the seal 14 is sleeved on the outside of the heating component 11, which can be understood as that, in the radial direction, the seal 14 is arranged on the side of the heating component 11 away from the heating chamber 110. In this way, the seal 14 is less affected by the airflow in the heating chamber 110. The seal 14 is spaced apart from the heating component 11, that is, the seal 14 is not in contact with the heating component 11, and the seal 14 is less affected by the temperature in the heating component 11. A heat insulation zone is formed between the seal 14 and the heating component 11. In some embodiments, the heat insulation zone is filled with air without the need to fill other heat insulation media.
[0042] like Figure 5 As shown, the sealing member 14 is connected to the first fixing seat 12 and the second fixing seat 13 at both ends in the first direction, that is, the sealing member 14 is connected to the first fixing seat 12 at one end in the first direction, and is connected to the second fixing seat 13 at the other end; the specific implementation method of the connection is not limited in the embodiment of the utility model, for example, abutment connection method, welding method, bonding method, or a sealing connection method using silicone or a sealing gasket can be adopted.
[0043] The heating device of the embodiment of the utility model includes a heating component, a first fixing seat, a second fixing seat and a sealing member. The interior of the heating component is provided with a heating chamber that passes through in the first direction, and the heating chamber is used to accommodate an aerosol generating substrate. The heating component has a first end and a second end that are opposite in the first direction; the first fixing seat abuts against the first end of the heating component; the second fixing seat abuts against the second end of the heating component; the sealing member is sleeved on the outside of the heating component and is spaced apart from the heating component; the sealing member is connected to the first fixing seat and the second fixing seat at both ends in the first direction, respectively. The embodiment of the utility model achieves the sealing of the heating device by sleeved on the outside of the heating component and by fixing the sealing member to the first fixing seat and the second fixing seat, thereby reducing the risk of aerosol leaking out and generating odor; and the sealing member is spaced apart from the heating member to form a heat insulation zone on the outside of the heating member, without the need to set up an additional heat insulation structure, which is conducive to reducing costs; the heating component abuts against the first fixing seat and the second fixing seat without the need for bonding with glue or silicone, thereby reducing the risk of harmful gases generated in the heating chamber.
[0044] Since the seal is spaced apart and sleeved on the outside of the heating element, the seal, the connecting medium between the seal and the first fixed seat, and the connecting medium between the seal and the second fixed seat will not directly contact the high-temperature airflow in the heating chamber, so the seal, the connecting medium between the seal and the first fixed seat, and the connecting medium between the seal and the second fixed seat are not easy to volatilize, that is, it is not easy to produce harmful gases. In addition, the connection between the heating component and the first fixed seat, and the connection between the heating component and the second fixed seat are both abutment connections, so the connecting medium between the heating component and the first fixed seat, and the connecting medium between the heating component and the second fixed seat are omitted, that is, it is not easy to produce harmful gases. Therefore, the heating device provided in the embodiment of the utility model is not easy to produce harmful gases.
[0045] In addition, since the seals are spaced apart on the outside of the heating element, the seals, the connection between the seals and the first fixed seat, and the connection between the seals and the second fixed seat are not easily affected by high temperatures, that is, they are not easily deformed, which helps to improve the sealing effect of the heating device and extend the service life of the heating device.
[0046] In some embodiments, Figure 5 As shown, the seal 14 is fixed to the first fixing seat 12 and the second fixing seat 13 by welding. For example, the welding can be any one of laser welding, ultrasonic welding and hot melt welding. During the welding process, flux can be filled between the seal 14 and the first fixing seat 12, and between the seal 14 and the second fixing seat 13 (for example, the flux can be a non-metal such as glue, or a metal and an auxiliary non-metal), or no flux can be filled.
[0047] like Figure 5 As shown, since the connection between the seal 14 and the first fixed seat 12, and the connection between the seal 14 and the second fixed seat 13 are both welding connections, a seal can be formed between the seal 14 and the first fixed seat 12, and between the seal 14 and the second fixed seat 13; thereby reducing the risk of aerosol leakage to the outside of the accommodating cavity, that is, reducing the risk of aerosol leakage to the outside of the heating device 1.
[0048] It is understandable that if abutment, silicone, glue or sealing gasket is used for sealing, gaps will appear between the seal and the first fixing seat, and between the seal and the second fixing seat due to thermal expansion and contraction, thereby affecting the sealing effect. Therefore, the embodiment of the utility model adopts welding, which is less susceptible to temperature than other connection methods, that is, less susceptible to thermal expansion and contraction, thereby helping to improve the sealing effect and service life of the heating device.
[0049] In some embodiments, Figure 5As shown in FIG. 1 , the gap between the heating component 11 and the sealing member 14 is greater than or equal to 0.1 mm and less than or equal to 5 mm. The gap can be understood as the thickness of the air layer between the heating component 11 and the sealing member 14, which is represented by K in the figure. The gap between the heating component 11 and the sealing member 14 can be uniform or non-uniform (e.g., Figure 5 and Figure 6 As shown). If the gap between the heating component 11 and the seal 14 is too small, for example, less than 0.1 mm, the seal 14 and the connection between the seal 14 and the two fixing seats 12 and 13 are close to the heating component 11, that is, they are easily affected by high temperature. If the gap between the heating component 11 and the seal 14 is too large, for example, greater than 5 mm, the size of the seal 14 is large, that is, the overall size of the heating device 1 is large, and it is not convenient to carry.
[0050] By limiting the size of the gap, the embodiment of the utility model can not only reduce the influence of the sealing member on the heating component, but also make the overall size of the heating device small and convenient to carry.
[0051] In some embodiments, Figure 5 and Figure 7 As shown, the first fixing seat 12 has a first end face 121 and a second end face 122 spaced apart in the radial direction; the radial direction is indicated by a dotted line in the figure, the first end face 121 can be a plane, an inclined surface or a curved surface, and the second end face 122 can be a plane, an inclined surface or a curved surface. The first fixing seat 12 also has a first protrusion 123 disposed between the first end face 121 and the second end face 122, and the first protrusion 123 protrudes and extends along the first end face 121 in a direction away from the second end face 122. Figure 5 and Figure 7 As shown, in the first direction, the relative positions of the first end face 121 and the second end face 122 include at least the following three situations: the first situation: the first end face 121 and the second end face 122 are flush; the second situation: the first end face 121 is closer to the second fixing seat 13 than the second end face 122; the third situation: the second end face 122 is closer to the second fixing seat 13 than the first end face 121.
[0052] Among them, the first end face 121 is against the first end of the heating component 11, and the second end face 122 is fixed to one end of the seal 14 in the first direction. The first protrusion and the heating component are arranged at intervals to form a heat insulation zone between the first protrusion and the heating component, thereby reducing the influence of the high temperature of the heating component on the first protrusion and the seal. The first protrusion and the seal are arranged at intervals to form a heat insulation zone between the first protrusion and the seal, thereby further reducing the influence of the high temperature of the heating component on the seal. In the embodiment of the utility model, through the arrangement of the first end face, the second end face and the first protrusion, even if there is a gap between the first end face and the heating component, the aerosol flows from the heating chamber to the gap between the first end face and the heating component, and needs to bypass the first protrusion to enter between the heating component and the seal. Therefore, by setting the first protrusion, the path of aerosol leakage is extended, and the difficulty of aerosol leakage is increased; and the seal and the heating component are arranged at intervals at the first end, thereby reducing the influence of the high temperature of the heating component on the seal.
[0053] In some embodiments, Figure 5 and Figure 8 As shown, the second fixing seat 13 is provided with a second protrusion 131 protruding along the first direction toward the first fixing seat 12, that is, the second protrusion 131 protrudes toward the first fixing seat 12. The second protrusion 131 is located between the sealing member 14 and the heating assembly 11 in the radial direction. The specific shape of the second protrusion 131 is not limited in the embodiment of the utility model. For example, the second protrusion 131 is annular, and the annular shape surrounds the outer side of the heating assembly 11 in the first direction, and surrounds the inner side of the sealing member 14 in the first direction.
[0054] like Figure 5 and Figure 8 As shown, the positional relationship between the heating component 11, the sealing member 14 and the second protrusion 131 includes at least the following three situations: the first situation is that only the heating component 11 abuts against the second protrusion 131; the second situation is that only the sealing member 14 abuts against the second protrusion 131; the third situation is that the heating component 11 and the sealing member 14 abut against the second protrusion 131 at the same time.
[0055] The embodiment of the utility model adopts the arrangement of the second protrusion. Even if there is a gap between the heating component and the second fixing seat, the aerosol needs to bypass the second protrusion to enter between the heating component and the seal from the heating chamber. Therefore, by providing the second protrusion, the path of aerosol leakage is extended and the difficulty of aerosol leakage is increased; and the seal and the heating component are kept at a distance at the second end, thereby reducing the influence of the high temperature of the heating component on the seal.
[0056] In some embodiments, Figure 8As shown, the second protrusion 131 abuts against the side of the sealing member 14 close to the heating assembly 11, that is, the sealing member 14 abuts against the outer side of the second protrusion 131 (the outer side, in Figure 5 In the embodiment of the utility model, the seal member 14 is positioned on the second fixing seat 13, which can be understood as the side facing the outside of the heating chamber 110, so as to facilitate the subsequent welding of the seal member 14 to the second fixing seat 13. Therefore, the embodiment of the utility model facilitates assembly and facilitates subsequent welding by abutting the seal member against the outer side of the second protrusion.
[0057] In some embodiments, Figure 8 As shown, the second fixing seat 13 is provided with a third protrusion 132 protruding along the first direction toward the first fixing seat 12, and the third protrusion 132 abuts against the inner side of the heating assembly 11 in the radial direction. Figure 5 In the embodiment of the utility model, the third protrusion is provided, and even if there is a gap between the heating component and the second fixing seat, the aerosol needs to bypass the third protrusion to enter between the heating component and the sealing member from the heating chamber. Therefore, by providing the third protrusion, the path of aerosol leakage is extended, and the difficulty of aerosol leakage is increased; and the heating component is positioned at the second fixing seat, which is convenient for assembly.
[0058] In some embodiments, Figure 5 As shown, a plurality of third protrusions 132 are provided, and the plurality of third protrusions 132 are spaced apart on the inner side of the heating component 11. In this way, there is a circumferential gap between two adjacent third protrusions 132, and the circumference is indicated by a dotted line c in the figure. It can be understood that when the heating device 1 is used by the user, the temperature of the heating component 11 is relatively high (for example, the temperature is 200-300°C); when it is not used, the temperature of the heating component 11 is at room temperature (for example, the temperature is 15-25°C); therefore, the heating component 11 is prone to thermal expansion and contraction. Since the heating component 11 is against the outer side of the third protrusion 132 and there is a circumferential gap between two adjacent third protrusions 132, the heating component 11 is prone to deformation at the gap. This gap is equivalent to providing a deformation space for the heating component 11.
[0059] The embodiment of the utility model provides deformation space for the heating component through the interval setting of the third protrusion, which helps to release the internal stress of the heating component and prolong the service life of the heating component.
[0060] In some embodiments, Figure 5As shown, the heating device 1 also includes a heat insulating member (not shown), which is arranged between the heating component 11 and the sealing member 14. The specific material and shape of the heat insulating member are not limited. Exemplarily, the heat insulating member is a ceramic sheet. The embodiment of the utility model further enhances the heat insulation effect of the heating component of the electronic atomization device by setting the heat insulating member.
[0061] The utility model also provides an electronic atomization device, such as Fig. 9 As shown, the electronic atomization device includes Figures 3 to 8 Any of the heating devices 1 shown. Exemplarily, in order to facilitate the control of the heating device 1, the electronic atomization device further includes an electrical component 3, and the electrical component 3 includes a circuit board, a battery, and the like.
[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
