Abstract
Description
Technical Field
[0001] This utility model belongs to the field of electronic atomization technology, and in particular relates to an atomizer and an electronic atomization device. Background Technology
[0002] Currently, side atomization has become the mainstream technology for ceramic electronic atomizers, offering advantages such as high conversion rate and high sweetness.
[0003] Lateral atomization typically employs a snap-fit structure where the ejector pin and ceramic heating element are laterally engaged, with "lateral" meaning the engagement direction is perpendicular to the axis of the electronic atomizing device. This structure can easily lead to excessive stress on the ceramic heating element. Due to the relatively low strength of the heating film on the ceramic heating element, the heating film is easily damaged by the ejector pin during assembly, resulting in reduced reliability of the atomizer after assembly. Utility Model Content
[0004] The purpose of this application is to provide an atomizer that addresses the problem of how to improve the reliability of the atomizer.
[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:
[0006] In a first aspect, an atomizer is provided, comprising: a heating base, a pin disposed on the heating base, a bracket having a supporting surface, a sealing element located on the supporting surface, a heating element connected to the sealing element, and a heating film disposed on the heating element and facing the pin; the bracket is snap-fitted to the heating base, and the heating film is pressed and electrically connected to the two pins; a gap is formed between the sealing element and the supporting surface, such that when the bracket snaps-fitted to the heating base, a portion of the sealing element moves into the gap.
[0007] In some embodiments, the projection of the ejector pin onto the support surface is located within the gap.
[0008] In some embodiments, the surface of the seal facing the support surface is provided with a clearance groove, and the inner wall of the clearance groove and the support surface together define the gap.
[0009] In some embodiments, the extension path of the clearance groove is along the axial direction of the ejector pin, and the two ends of the clearance groove extend to the opposite ends of the seal, respectively.
[0010] In some embodiments, two clearance grooves are arranged at intervals, and the two clearance grooves are respectively provided for the two ejector pins; the sealing member is also provided with a support portion that abuts against the support surface, and the support portion is located between the two clearance grooves.
[0011] In some embodiments, the distance of the gap along the support surface in the direction pointing to the seal is greater than or equal to 0.1 mm.
[0012] In some embodiments, the bracket has a receiving cavity with an opening and the supporting surface is located at the bottom of the receiving cavity, and the sealing element is located in the receiving cavity.
[0013] In some embodiments, slots are provided on the opposite sides of the cavity wall of the accommodating cavity, and buckles are provided on the opposite sides of the outer surfaces of the heating base, with the two buckles respectively engaging with the two slots.
[0014] In some embodiments, the buckle has a snap-on state that engages with the slot and a release state that disengages from the slot, with the two buckles being in the snap-on state sequentially, so that the two buckles engage with the two slots sequentially and respectively.
[0015] In a second aspect, an electronic atomizing device is provided, which includes the atomizer and a battery assembly, wherein the ejector pin is electrically connected to the battery assembly.
[0016] The beneficial effects of this application are as follows: by forming a gap between the support surface and the seal, when the heating base is snapped into the bracket, the bracket undergoes a certain elastic deformation, which in turn causes the seal to undergo elastic deformation. The seal can move locally into the gap, thereby increasing the relaxation between the heating film and the ejector pin. Before the bracket and the heating base are fully engaged, the compressive force between the ejector pin and the heating film is low. When the heating film moves laterally relative to the ejector pin, the friction between the ejector pin and the heating film can be reduced, thereby avoiding physical damage to the heating film due to excessive friction and improving the reliability of the atomizer.

[0029] Please see Figures 1 to 3 This application provides an atomizer and an electronic atomizing device 100 having the same.
[0030] Please see Figure 2 , Figure 4 and Figure 5 The atomizer includes: a heating base 11, a pin 12 disposed on the heating base 11, a bracket 15 having a support surface 152, a sealing element 14 located on the support surface 152, a heating element 13 connected to the sealing element 14, and a heating film 132 disposed on the heating element 13 and facing the pin 12. The pin 12 is elongated and made of a conductive material, such as copper. One end of the pin 12 is inserted into the heating base 11, and the other end of the pin 12 extends away from the heating base 11 so that the heating film 132 can electrically abut against the pin 12 during subsequent assembly. Two pins 12 are arranged at intervals. The bracket 15 is snap-fitted to the heating base 11, that is, both sides of the bracket 15 can be snap-fitted to both sides of the heating base 11, thereby allowing the bracket 15 and the heating base 11 to be detachably connected.
[0031] Please see Figure 2 , Figure 4 and Figure 5 After the bracket 15 and the heating base 11 are snapped together, the heating film 132 is pressed and electrically connected to the two ejector pins 12 along the direction of the fastening of the bracket 15 and the heating base 11. It can be understood that the two ejector pins 12 are respectively connected to the two electrodes of the power supply, and the heating film 132 can be electrically connected to the power supply through the ejector pins 12. The sealing element 14 can be made of a flexible and elastic material, such as silicone. When the sealing element 14 is compressed, it can undergo elastic deformation, and after the pressure is released, the sealing element 14 can return to its original shape.
[0032] Please see Figure 2 , Figure 4 and Figure 5 A gap 141 is formed between the sealing member 14 and the support surface 152, so that when the bracket 15 is snapped into the heating base 11, part of the sealing member 14 moves into the gap 141 to reduce the compressive force between the heating film 132 and the ejector pin 12.
[0033] Please see Figure 2 , Figure 4 and Figure 5The atomizer provided in this application embodiment has a gap 141 formed between the support surface 152 and the seal 14. When the heating base 11 is snapped into the bracket 15, the bracket 15 undergoes a certain elastic deformation, which in turn causes the seal 14 to undergo elastic deformation. The seal 14 can move locally into the gap 141, thereby increasing the relaxation between the heating film 132 and the ejector pin 12. Before the bracket 15 and the heating base 11 are fully engaged, the squeezing force between the ejector pin 12 and the heating film 132 is low. When the heating film 132 moves laterally relative to the ejector pin 12, the friction between the ejector pin 12 and the heating film 132 can be reduced, thereby avoiding physical damage to the heating film 132 due to excessive friction and improving the reliability of the atomizer.
[0034] It is understandable that the bracket 15 and the heating base 11 can both be made of plastic, so that the bracket 15 and the heating base 11 can be integrally molded through injection molding.
[0035] Please see Figure 5 and Figure 6 The sealing element 14 is rectangular in shape and has a positioning cavity 143, in which the heating element 13 is partially housed.
[0036] Optionally, the heating element 13 in this embodiment is a ceramic heating element 13.
[0037] Please see Figure 2 , Figure 4 and Figure 5 In some embodiments, the projection of the ejector pin 12 onto the support surface 152 is located within the gap 141, that is, the portion of the seal 14 facing the ejector pin 12 is suspended, thereby allowing the seal 14 at the corresponding position to move into the gap 141.
[0038] It is understandable that during the assembly of the bracket 15 and the heating base 11, the direction of the compressive force between the ejector pin 12 and the heating film 132 is through the gap 141. Thus, when the bracket 15 deforms, the seal 14, which is located opposite the ejector pin 12, can also undergo elastic deformation and move into the gap 141, thereby minimizing the friction between the ejector pin 12 and the seal 14 and preventing physical damage to the heating film 132.
[0039] Please see Figure 2 , Figure 4 and Figure 5Optionally, by arranging the projection of the ejector pin 12 within the gap 141, the friction caused by the lateral movement of the heating film 132 is reduced. After the bracket 15 and the heating base 11 are assembled, the seal 14 can undergo slight deformation within the gap 141, thereby maintaining a suitable compressive force between the ejector pin 12 and the heating film 132, and preventing the heating film 132 from being crushed or damaged.
[0040] Please see Figure 5 and Figure 6 In some embodiments, the surface of the seal 14 facing the support surface 152 is provided with a relief groove 143, and the inner wall of the relief groove 143 and the support surface 152 together define the gap 141.
[0041] Optionally, along the width direction of the relief groove 143, the relief groove 143 extends to the surface of one side of the seal 14, and the relief groove 143 is located at the edge of the seal 14. The cross-sectional shape of the relief groove 143 is L-shaped and located directly below the ejector pin 12. Thus, by moving the bottom of the relief groove 143 toward the support surface 152, the seal 14 can undergo local elastic deformation. The relief groove 143 located directly below the ejector pin 12 can reduce the friction between the ejector pin 12 and the heating film 132 when the bracket 15 is snapped into the heating base 11.
[0042] Please see Figure 5 and Figure 6 In some embodiments, the extension path of the relief groove 143 is along the axial direction of the ejector pin 12, and the two ends of the relief groove 143 extend to the opposite ends of the seal 14.
[0043] Optionally, the extension path of the relief groove 143 is arranged along the axial direction of the ejector pin 12, so that the gap 141 formed between the seal 14 and the support surface 152 also extends along the axial direction of the ejector pin 12 to the opposite ends of the seal 14. This ensures that the contact position between the ejector pin 12 and the heating film 132 is within the range of the gap 141 as projected onto the support surface 152. This effectively reduces the compressive force between the ejector pin 12 and the heating film 132, reduces the friction between the two during assembly, and improves the reliability of the atomizer.
[0044] Please see Figure 2 , Figure 4 and Figure 5 In some embodiments, two clearance grooves 143 are arranged at intervals, and the two clearance grooves 143 are respectively set for the two ejector pins 12. During the assembly process of the bracket 15 and the heating base 11, the friction between the heating film 132 and the two ejector pins 12 can be reduced by the two clearance grooves 143, so as to avoid physical damage to the heating film 132.
[0045] Please see Figure 2 , Figure 4 and Figure 5 In some embodiments, the sealing member 14 is further provided with a support portion 142 that abuts against the support surface 152, and the support portion 142 is located between the two relief grooves 143.
[0046] Please see Figure 2 , Figure 4 and Figure 5 Optionally, the support portion 142 and the support surface 152 are in surface-to-surface contact. The support portion 142 is elongated and there are two of them. The two support portions 142 are arranged at intervals along the axial direction of the ejector pin 12 or the atomizer. By having the two support portions 142 jointly abut against the support surface 152, the support surface 152 can provide stable support for the seal 14. The number of support portions 142 can also be three or more. There is no limitation here, and it can be selected according to the actual situation.
[0047] In some embodiments, the distance of the gap 141 along the direction from the support surface 152 to the seal 14 is greater than or equal to 0.1 mm. For example, the size of the gap 141 can be 0.1 mm, 0.15 mm, 0.18 mm, 0.2 mm, 0.22 mm, 0.26 mm, or 0.3 mm, and the maximum value of the gap 141 can be limited to 0.5 mm to avoid loosening of the assembly due to an excessively large gap 141, and also to facilitate the compactness of the overall structure.
[0048] Please see Figure 7 In some embodiments, the bracket 15 is provided with a receiving cavity 153, the receiving cavity 153 has an opening and the support surface 152 is located at the bottom of the receiving cavity 153, and the sealing member 14 is located in the receiving cavity 153.
[0049] Please see Figure 5 and Figure 6 Optionally, when the bracket 15, the seal 14 and the heating element 13 are assembled, the seal 14 is disposed at the bottom of the accommodating cavity 153 through the opening of the accommodating cavity 153, the heating element 13 is inserted into the positioning cavity 143 of the seal 14, and a pressure-increasing strip 144 is protruding on the peripheral surface of the seal 14, the pressure-increasing strip 144 abuts against the cavity wall of the accommodating cavity 153, thereby improving the stability of the seal 14.
[0050] Please see Figure 2 , Figure 4 and Figure 7 In some embodiments, slots 151 are provided on the opposite two sides of the cavity wall of the accommodating cavity 153, and buckles 161 are provided on the two opposite outer surfaces of the heating base 11. The two buckles 161 are respectively fastened to the two slots 151.
[0051] Optionally, the bracket 15 and the heating base 11 can be detachably connected by the cooperation of the buckle 161 and the slot 151. In other embodiments, the slot 151 can be opened in the heating base 11, and the buckle 161 can be protruded from the inner wall of the receiving cavity 153. There is no limitation here, and the choice can be made according to the actual situation.
[0052] Please see Figure 2 , Figure 4 and Figure 7 In some embodiments, the buckle 161 has a snap-fit state that engages with the slot 151 and a disengaged state that disengages from the slot 151. The two buckles 161 are in the snap-fit state sequentially, so that they engage with the two slots 151 sequentially and respectively. During the assembly of the bracket 15 and the heating base 11, the two buckles 161 are first positioned opposite the two slots 151 respectively. Then, the buckle 161 on one side of the heating base 11 is snapped onto the corresponding slot 151 on the bracket 15, and then the buckle 161 on the other side of the heating base 11 is snapped onto the corresponding slot 151 on the other side of the bracket 15. By sequentially snapping the two buckles 161 into the snap-fit state, the seal 14 only moves into the gap 141 on one side, while the gap 141 on the other side is not compressed. The seal 14 remains slightly loose, thereby improving the reliability of the heating film 132 during assembly and preventing physical damage.
[0053] Please see Figure 2 , Figure 4 and Figure 5 The assembly process of the bracket 15 and the heating base 11 will be described below, taking into account the structural characteristics of the atomizer:
[0054] First, the heating element 13 is placed in the positioning cavity 143 of the sealing element 14, and then the sealing element 14 is placed into the receiving cavity 153, so that the bracket 15, the sealing element 14 and the heating element 13 form an assembly, wherein the heating film 132 is located on the outer surface of the heating element 13.
[0055] Next, insert the ejector pin 12 into the fixing hole of the heating base 11, so that the ejector pin 12 and the heating base 11 form another component.
[0056] Next, the slot 151 on one side of the cavity wall of the accommodating cavity 153 is fastened to a buckle 161 on the heating base 11, causing the drive bracket 15 to undergo elastic deformation, causing the other side of the cavity wall of the accommodating cavity 153 to expand outward, so that the slot 151 on the cavity wall can overcome the corresponding buckle 161. At this time, the sealing member 14 drives the heating element 13 to move laterally relative to the ejector pin 12. There is friction between the two ejector pins 12 and the heating film 132. Since the two sealing members 14 are provided with two gaps 141, when the cavity wall of the accommodating cavity 153 expands outward, the two ends of the sealing member 14 move locally into the two gaps 141 respectively, thereby reducing the squeezing force between the two ejector pins 12 and the heating film 132, thereby reducing the friction between the ejector pins 12 and the heating film 132. After the two buckles 161 are fastened to the two slots 151 respectively, the seal 14 and the heating element 13 move laterally in opposite directions relative to the two ejector pins 12. Since both ends of the seal 14 are suspended, the pressure between the ejector pins 12 and the heating film 132 is kept within a reasonable range, thus preventing the heating film 132 from being squeezed and damaged.
[0057] Please see Figure 4 and Figure 5 In some embodiments, the heating element 13 is provided with an atomizing surface 131, and the heating film 132 is laid on the atomizing surface 131, with the atomizing surface 131 parallel to the axial direction of the ejector pin 12.
[0058] Optionally, the atomizer in this embodiment is a lateral atomizer. By laying the heating film 132 on the atomizing surface 131 of the heating element 13 and setting it parallel to the axial direction of the atomizer, the conversion rate and sweetness of the aerosol can be improved, thus enhancing the user's inhalation experience.
[0059] Please see Figure 1 and Figure 3 This utility model also proposes an electronic atomizing device 100, which includes an atomizer. The specific structure of the atomizer is as described in the above embodiments. Since this electronic atomizing device 100 adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
[0060] Please see Figure 1 and Figure 3 In some embodiments, the electronic atomizing device 100 further includes a battery assembly 102, and the ejector pin 12 is electrically connected to the battery assembly 102.
[0061] The battery assembly 102 includes a battery for powering the atomizer and control circuitry for controlling the atomizer's heating. The atomizer is used to contain a liquid matrix and, upon being powered on, heats and atomizes the liquid matrix to generate an aerosol.
[0062] In some embodiments, the atomizer and the battery assembly 102 may both be generally elliptical cylindrical in shape, and the two may be mechanically and electrically connected together along the axial direction.
[0063] The atomizer and battery assembly 102 can be detachably connected together via magnetic connection, threaded connection, snap-fit connection, or other similar methods. Understandably, in other embodiments, the atomizer and battery assembly 102 can also be non-detachably connected together. Furthermore, the cross-sectional shape of the atomizer and / or battery assembly 102 is not limited to an elliptical shape; it can also be circular, racetrack-shaped, rectangular, or other shapes.
[0064] Please see Figure 1 and Figure 3 Optionally, the electronic atomizing device 100 further includes a housing 101, in which both the atomizer and the battery assembly 102 are located.
[0065] The electronic atomizing device 100 provided in this application embodiment uses the above-mentioned atomizer. By forming a gap 141 between the support surface 152 and the sealing member 14, when the heating base 11 is snapped into the bracket 15, the bracket 15 undergoes a certain elastic deformation, which in turn causes the sealing member 14 to undergo elastic deformation. The sealing member 14 can move locally into the gap 141, thereby increasing the relaxation between the heating film 132 and the ejector pin 12. Before the bracket 15 and the heating base 11 are fully engaged, the squeezing force between the ejector pin 12 and the heating film 132 is low. When the heating film 132 moves laterally relative to the ejector pin 12, the friction between the ejector pin 12 and the heating film 132 can be reduced, thereby avoiding physical damage to the heating film 132 due to excessive friction and improving the reliability of the atomizer.
[0066] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
