Description

Technical Field

[0001] This application relates to the field of atomizing equipment technology, and more specifically, to a housing assembly and an electronic atomizing device. Background Technology

[0002] In electronic atomizing devices, the outer shell and bottom cover are typically bonded together with adhesive to ensure stability and sealing during use. This structural design improves the product's robustness, water resistance, and dustproofing to a certain extent, and also offers high assembly efficiency in the manufacturing process, hence its widespread adoption. However, when the battery performance degrades, the bond between the outer shell and bottom cover makes it difficult to process or recycle the battery separately, forcing the entire electronic atomizing device to be discarded. This not only leads to underutilization of battery resources but also increases the environmental burden during product disposal. Utility Model Content

[0003] The purpose of this application is to provide a housing assembly and an electronic atomizing device, which aims to solve the technical problem in the related art where the bonding and fixing between the outer shell and the bottom cover of the electronic atomizing device makes it difficult to handle or recycle the battery cell separately.

The bracket cooperates with the bottom cover to form a first receiving cavity, and the bottom cover is provided with a first through hole. The elastic structure is configured such that after an external force is applied to the bracket through the first through hole to separate the first engaging portion from the second engaging portion, a relative displacement is generated between the first engaging portion and the second engaging portion, so that the first engaging portion and the second engaging portion remain separated when the external force is removed.

[0005] In some implementations, the bottom cover has an insertion cavity into which a portion of the outer shell is inserted, and the first engaging portion and the second engaging portion mutually limit each other in the direction in which the outer shell is inserted into the insertion cavity, so that the outer shell and the bottom cover remain relatively fixed.

[0006] In some implementations, the first engaging part is a boss structure, the second engaging part is a boss structure, and the two boss structures abut against each other. Alternatively, one of the first engaging portion and the second engaging portion may be a boss structure and the other may be a groove structure, with at least a portion of the boss structure extending into the groove structure.

[0007] In some implementations, the bracket has a base, and the outer shell is fixedly connected to the base; The elastic structure is located in the insertion cavity, the first engaging part is disposed on the base, and the second engaging part is located on the inner wall of the bottom cover.

[0008] In some implementations, the base includes a partition portion and at least one elastically deformable portion; the elastically deformable portion is fixedly connected to the partition portion, the elastically deformable portion extends into the insertion cavity, and at least one of the elastically deformable portions is provided with the first engaging portion; The elastic deformation portion is configured to deform in a direction away from the second engaging portion under the action of an external force, so as to separate the first engaging portion from the second engaging portion.

[0009] In some implementations, the elastic structure is fixedly connected to the elastic deformation portion, and the elastic structure abuts against the bottom cover.

[0010] In some implementations, the elastic structure includes two elastic feet, each elastic foot having a connecting end and a free end. The connecting end of the elastic foot is fixedly connected to the elastic deformation part, and the free end of the elastic foot is used to abut against the bottom cover. The distance between the connecting ends of the two elastic feet is greater than the distance between the free ends of the two elastic feet.

[0011] In some implementations, the support includes two elastic structures distributed circumferentially along the partition portion.

[0012] In some implementations, one of the base and the bottom cover abuts against the elastic structure, while the other is fixedly connected to or abuts against the elastic structure.

[0013] In some implementations, the housing assembly further includes a locking pin for applying external force to the bracket by inserting it into the first through hole to separate the first engaging portion from the second engaging portion.

[0014] In some implementations, the housing assembly further includes a liquid storage assembly and a suction nozzle, the suction nozzle being fixedly connected to the housing, the liquid storage assembly being fixedly connected to the support, and the liquid storage assembly having a liquid storage cavity; the housing is fixedly connected to the liquid storage assembly.

[0015] This application provides an electronic atomizing device, including: a battery cell and a housing assembly as described in any of the above implementations, wherein the battery cell is installed in the first receiving cavity.

[0016] In some implementations, the electronic atomizing device further includes a printed circuit board assembly electrically connected to the battery cell.

[0017] The main advantages of the housing assembly and electronic atomizing device provided in this application are: This application achieves a mechanical connection between the outer shell and the bottom cover by engaging the first and second engaging parts. This ensures a tight connection between the outer shell and the bottom cover during normal use, maintaining the structural stability of the device. During disassembly, external force can be applied through the first through-hole to separate the first and second engaging parts, achieving non-destructive disassembly of the bottom cover and the outer shell. This facilitates the individual removal and replacement of the battery cells after the shell assembly is applied to an electronic atomization device, reducing resource waste, increasing the reuse rate of key components, and reducing the environmental damage caused by discarded electronic atomization devices. Furthermore, the design of the first and second engaging parts and the elastic structure also facilitates rapid assembly of the shell assembly, eliminating the need for complex glue application and curing processes during production, thus reducing production costs.

[0021] In related technologies, the outer shell and bottom cover of electronic atomizing devices are typically bonded together with adhesive to ensure the stability and sealing of the device during use. This structural design can improve the product's robustness, water resistance, and dust resistance to a certain extent, and also has high assembly efficiency in the manufacturing process, hence its widespread adoption. However, when the battery cell performance degrades, due to the bond between the outer shell and bottom cover, the battery cell is difficult to handle or recycle separately, and the entire electronic atomizing device must be discarded. This not only leads to the underutilization of battery cell resources but also increases the environmental burden during product disposal.

[0022] Therefore, this application provides a housing assembly and an electronic atomizing device to solve the problems in the related art.

[0023] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0024] Combination Figure 1 and Figure 2 As shown, the electronic atomizing device provided in this application embodiment includes: such as a battery cell 101 and a housing assembly, wherein the battery cell 101 is installed in the housing assembly.

[0025] In some embodiments, the electronic atomizing device further includes a printed circuit board assembly (PCBA) 125, which is electrically connected to the battery cell 101 via electrical connection wires. The printed circuit board assembly 125 is mounted in the housing assembly.

[0026] Combination Figures 3 to 5 As shown, the housing assembly provided in this application embodiment includes: a housing 102, a bracket 103, and a bottom cover 104; the bracket 103 is connected to the housing 102, and the bracket 103 has an elastic structure 105 and a first engaging portion 106; the bottom cover 104 has a second engaging portion 107.

[0027] Combination Figures 6 to 8 As shown, the first engaging part 106 and the second engaging part 107 engage to connect the outer shell 102 and the bottom cover 104. The bracket 103 cooperates with the bottom cover 104 to form the first receiving cavity 108. The bottom cover 104 is provided with a first through hole 109.

[0028] Combination Figure 9 and Figure 10As shown, the elastic structure 105 is configured such that after an external force is applied to the bracket 103 through the first through hole 109 to separate the first engaging portion 106 and the second engaging portion 107, a relative displacement is generated between the first engaging portion 106 and the second engaging portion 107, so that the first engaging portion 106 and the second engaging portion 107 remain in a separated state when the external force is removed.

[0029] The housing assembly provided in this application embodiment achieves a mechanical connection between the outer shell 102 and the bottom cover 104 by engaging the first engaging portion 106 and the second engaging portion 107. This ensures a tight connection between the outer shell 102 and the bottom cover 104 during normal use, maintaining the structural stability of the device. During disassembly, external force is applied through the first through hole 109 to separate the first engaging portion 106 and the second engaging portion 107, achieving non-destructive disassembly of the bottom cover 104 and the outer shell 102. This facilitates the individual disassembly and replacement of the battery cell 101 after the housing assembly is applied to an electronic atomization device, reducing resource waste, increasing the reuse rate of key components, and reducing the environmental damage caused by discarded electronic atomization devices. Furthermore, the design of the first engaging portion 106, the second engaging portion 107, and the elastic structure 105 also facilitates rapid assembly of the housing assembly, eliminating the need for complex glue application and curing processes during production, thus reducing production costs.

[0030] For example, the battery cell 101 is installed in the first receiving cavity 108, and the printed circuit board assembly 125 is installed in the first receiving cavity 108. The number of first engaging portions 106 can be one or more, and the number of second engaging portions 107 can be one or more, with a one-to-one correspondence between the multiple first engaging portions 106 and the multiple second engaging portions 107. After the first engaging portions 106 and the second engaging portions 107 are engaged, the outer casing 102 and the bottom cover 104 can be relatively fixed, thus protecting the battery cell 101 and ensuring safety during use. The shape of the first through hole 109 can be circular, elliptical, or polygonal. When an external force is applied to the bracket 103 through the first through hole 109, although the first engaging part 106 and the second engaging part 107 can be separated, the elastic potential energy stored in the elastic structure 105 allows the bottom cover 104 to move a certain distance relative to the outer shell 102 in the height direction of the shell assembly. This creates a relative displacement between the first engaging part 106 and the second engaging part 107 in the height direction of the shell assembly. When the external force is removed, there is a gap between the first engaging part 106 and the second engaging part 107, preventing them from engaging, thus achieving the disassembly of the outer shell 102 and the bottom cover 104. During the production and assembly of the shell assembly, when the first engaging part 106 and the second engaging part 107 engage, the elastic structure 105 is in a compressed state to store elastic potential energy. The height direction of the shell assembly is the height direction of the electronic atomizing device; the height direction of the shell assembly is the ZZ direction.

[0031] It is understood that the housing assembly provided in this application embodiment is not limited to electronic atomization devices, but can also be applied to other electronic devices, such as mobile phones, portable walkie-talkies, or electric shavers.

[0032] Combination Figures 3 to 5 As shown, in some embodiments, the bottom cover 104 has an insertion cavity 110, into which a portion of the outer shell 102 is inserted. The first engaging portion 106 and the second engaging portion 107 mutually limit each other in the direction in which the outer shell 102 is inserted into the insertion cavity 110, so that the outer shell 102 and the bottom cover 104 remain relatively fixed. This ensures that the outer shell 102 and the bottom cover 104 are relatively fixed in the height direction, which helps to ensure the overall rigidity and mechanical strength of the housing assembly. The partial structure of the outer shell 102 is inserted into the insertion cavity 110 of the bottom cover 104, and a tight mating interface can be formed between the two. Combined with the limiting effect of the first engaging portion 106 and the second engaging portion 107 in the insertion direction, the gap at the connection can be effectively reduced, the sealing performance of the housing assembly can be improved, and the requirements of electronic atomization devices for waterproof and dustproof functions can be met. For example, the direction in which the outer shell 102 is inserted into the insertion cavity 110 can be parallel to the height direction of the shell assembly. The insertion cavity 110 forms the first receiving cavity 108, and the first engaging portion 106 and the second engaging portion 107 are also located in the insertion cavity 110, which helps to ensure the aesthetic appearance of the outer surface of the shell assembly. After the first engaging portion 106 and the second engaging portion 107 mutually limit each other in the height direction of the shell assembly, the bottom cover 104 and the outer shell 102 will not move relative to each other in the height direction of the shell assembly. Since part of the structure of the outer shell 102 is inserted into the insertion cavity 110, it helps to ensure that the outer shell 102 will not bend relative to the height direction of the shell assembly. The orthographic projection of the edge contour of the insertion cavity 110 in the projection plane can be non-circular, such as elliptical, polygonal, or polygonal with rounded corners, which can prevent the outer shell 102 from rotating about an axis parallel to the height direction of the shell assembly. The projection plane is perpendicular to the height direction of the shell assembly.

[0033] It should be noted that in some other possible embodiments, the orthographic projection of the edge contour of the insertion cavity 110 in the projection plane can also be circular. In this case, there can be an anti-rotation structure between the outer shell 102 and the bottom cover 104. For example, a guide protrusion can be provided on the outer shell 102, and a guide groove can be provided on the inner wall of the insertion cavity 110.

[0034] In some embodiments, the first engaging portion 106 and the second engaging portion 107 are both boss structures, and the two boss structures abut against each other; or, one of the first engaging portion 106 and the second engaging portion 107 is a boss structure, and the other is a recess structure, with at least a portion of the boss structure extending into the recess structure. This abutment between the two boss structures, or the insertion of a boss structure into a recess structure, provides a more stable mechanical restraint, ensuring the relative fixation of the housing assembly in the height direction. For example, see... Figure 8 As shown, the first engaging part 106 is a boss structure, while the second engaging part 107 is a groove structure.

[0035] See Figure 4 As shown, in some embodiments, the bracket 103 has a base 111, and the outer shell 102 is fixedly connected to the base 111; the elastic structure 105 is located in the insertion cavity 110, the first engaging portion 106 is disposed on the base 111, and the second engaging portion 107 is located on the inner wall of the bottom cover 104. This facilitates the assembly of the housing assembly. For example, after the elastic structure 105 is located in the first receiving cavity 108, it is located in the insertion cavity 110; the inner wall of the bottom cover 104 is the inner wall of the insertion cavity 110; the outer shell 102 and the base 111 can be fixedly connected by engaging connection or adhesive connection; the fixed connection between the outer shell 102 and the base 111 realizes the fixed connection between the outer shell 102 and the bracket 103. Thus, when the bracket 103 and the bottom cover 104 are engaged by the first engaging portion 106 and the second engaging portion 107, the fixed connection between the outer shell 102 and the bottom cover 104 is realized. The elastic structure 105 can be located between the base 111 and the bottom of the insertion cavity 110.

[0036] See Figure 4As shown, in some embodiments, the base 111 includes a partition portion 113 and at least one elastically deformable portion 112. The elastically deformable portion 112 is fixedly connected to the partition portion 113 and extends into the insertion cavity 110. At least one elastically deformable portion 112 is provided with a first engaging portion 106. The elastically deformable portion 112 is configured to deform away from the second engaging portion 107 under the action of an external force, so that the first engaging portion 106 and the second engaging portion 107 are separated. The elastically deformable portion 112 facilitates the assembly of the housing assembly and the disassembly between the outer shell 102 and the bottom cover 104. For example, the elastically deformable portion 112 and the partition portion 113 can be integrally formed using an integral molding process, thereby achieving a fixed connection between the elastically deformable portion 112 and the partition portion 113. The partition portion 113 and the outer shell 102 can be fixedly connected by a snap-fit ​​connection or by an adhesive connection, thereby fixing the outer shell 102 and the base 111 together. When the elastic deformation portion 112 deforms away from the second engaging portion 107 under the action of external force, it also deflects relative to the height direction of the housing assembly. There can be two elastic deformation portions 112, one of which is provided with the first engaging portion 106, and the other elastic deformation portion 112 may not be provided with the first engaging portion 106. The two elastic deformation portions 112 can be distributed circumferentially along the partition portion 113. There can be one first through hole 109 on the bottom cover 104. The first through hole 109 corresponds to the elastic deformation portion 112 provided with the first engaging portion 106, so that force can be applied from the first through hole 109 to the elastic deformation portion 112 provided with the first engaging portion 106, so that the elastic deformation portion 112 deflects relative to the height direction of the housing assembly.

[0037] See Figure 4 As shown, in some embodiments, the elastic deformation portion 112 can be a plate-like structure; the elastic deformation portion 112 may include a support plate 114 and multiple ribs 116. One end of the rib 116 is fixedly connected to the partition portion 113, and the other end of the rib 116 is connected to the support plate 114. The first through hole 109 corresponds to the support plate 114. In this way, the support plate 114 and the partition portion 113 are connected by multiple ribs 116, so that when force is applied to the support plate 114 through the first through hole 109, the ribs 116 of the elastic deformation portion 112 can undergo elastic deformation, thereby causing the first engaging portion 106 to separate from the second engaging portion 107.

[0038] In some embodiments, the elastic structure 105 is fixedly connected to the base 111 and abuts against the bottom cover 104, which facilitates reducing the number of parts and simplifying assembly. For example, the elastic structure 105 is fixedly connected to the elastic deformation portion 112, and the elastic structure 105 and the elastic deformation portion 112 can be integrally formed using a molding process, so that the elastic structure 105 can be manufactured simultaneously with the base 111.

[0039] It should be noted that in some other possible embodiments, the elastic structure 105 may abut against the base 111 and be fixedly connected to the bottom cover 104; or, the elastic structure 105 may abut against the base 111 and the bottom cover 104; when the elastic structure 105 abuts against the base 111 and the bottom cover 104 respectively, the elastic structure 105 may be a spring or an elastic body.

[0040] See Figure 4 As shown, in some embodiments, the elastic structure 105 includes two elastic legs 117, each having a connecting end 118 and a free end 119. The connecting end 118 of the elastic leg 117 is fixedly connected to the elastic deformation portion 112, and the free end 119 of the elastic leg 117 is used to abut against the bottom cover 104. The distance between the connecting ends 118 of the two elastic legs 117 is greater than the distance between the free ends 119 of the two elastic legs 117, thus forming an inwardly converging geometric structure, which is beneficial to improving the preload of the elastic legs 117 and reducing the space occupied by the elastic legs 117. For example, the elastic legs 117 and the elastic deformation portion 112 can be integrally formed into a single structure; the connecting end 118 of the elastic leg 117 is fixedly connected to the support plate 114, and the first engaging portion 106 is located on the support plate 114. When the bottom cover 104 is connected to the outer shell 102, the free end 119 of the elastic foot 117 abuts against the bottom of the insertion cavity 110, and the elastic foot 117 is in a compressed state.

[0041] In some embodiments, the support 103 may include two elastic structures 105 distributed circumferentially along the partition portion 113. For example, two elastic deformation portions 112 are respectively connected to the elastic structures 105, thus facilitating the separation of the bottom cover 104 from the outer casing 102.

[0042] It is understood that in some other possible embodiments, when there are multiple elastic structures 105 in the housing assembly, at least one elastic structure 105 abuts against one of the base 111 and the bottom cover 104, and the other of the base 111 and the bottom cover 104 is fixedly connected; at least one elastic structure 105 abuts against the base 111 and the bottom cover 104 respectively, and the elastic structure 105 abutting against the base 111 and the bottom cover 104 respectively can be a spring or an elastic body.

[0043] See Figure 11 As shown, in some embodiments, the housing assembly further includes a locking pin 120, which is used to apply external force to the bracket 103 by inserting into the first through hole 109 to separate the first engaging portion 106 from the second engaging portion 107. Exemplarily, the locking pin 120 may include a handle 121 and a rod structure 122, the rod structure 122 being fixedly connected to the handle 121. The rod structure 122 can be inserted into the first through hole 109 to push the support plate 114, causing the elastic deformation portion 112 to undergo elastic deformation. The handle 121 may be circular, elliptical, or oblong.

[0044] It should be noted that in some other possible embodiments, the housing assembly may not include the pin 120. The user only needs to insert the pin-like structure into the first through hole 109 and the elastic deformation part 112 to cause elastic deformation.

[0045] Combination Figure 1 and Figure 2 As shown, in some embodiments, the electronic atomizing device further includes a display screen 123, which is electrically connected to the printed circuit board assembly 125 to display the charge level of the battery cell 101. A transparent cover plate 124 may be installed on one side of the bottom cover 104, allowing the content displayed on the display screen 123 to be seen through the transparent cover plate 124. The display screen 123 is installed in the first receiving cavity 108. The battery cell 101 and the printed circuit board assembly 125 may have a buffer pad 126; a buffer pad 126 may be provided between the battery cell 101 and the bottom cover 104, and the buffer pad 126 may be made of EVA material.

[0046] Combination Figures 12 to 14As shown, in some embodiments, the housing assembly further includes a liquid storage component and a suction nozzle 127. The suction nozzle 127 is fixedly connected to the housing 102, and the liquid storage component is fixedly connected to the support 103. The liquid storage component has a liquid storage cavity 131; the housing 102 is fixedly connected to the liquid storage component. The liquid storage cavity 131 stores an aerosol matrix, which can form an aerosol when heated. For example, the liquid storage component is housed in the inner cavity of the housing 102; the liquid storage component includes a liquid storage shell 128, an upper cap 129, and a lower cap 130; the upper end of the liquid storage shell 128 is sealed to the upper cap 129, and the lower end of the liquid storage shell 128 is sealed to the lower cap 130. The liquid storage shell 128, the upper cap 129, and the lower cap 130 cooperate to form the liquid storage cavity 131; a first absorbent cotton 132 may be provided in the liquid storage cavity 131 to achieve the storage of the aerosol matrix. The liquid storage shell 128 is located inside the cavity of the outer shell 102. The liquid storage shell 128 is fixed to the support 103, and the outer shell 102 is fixedly connected to the liquid storage shell 128, thereby indirectly realizing the fixed connection between the outer shell 102 and the support 103. Since the outer shell 102 is fixedly connected to the support 103, the bottom cover 104 is fixedly connected to the base 111 of the support 103, thereby realizing the fixed connection between the outer shell 102 and the bottom cover 104.

[0047] Combination Figures 12 to 14 As shown, in some embodiments, the bracket 103 has a first locking platform 133, and the liquid storage shell 128 has a first locking hole 134. The first locking platform 133 is inserted into the first locking hole 134 to achieve a fixed connection between the liquid storage shell 128 and the bracket 103 by locking. The liquid storage shell 128 also has a second locking platform 136, and the outer shell 102 has a second locking hole 135. The second locking platform 136 is inserted into the second locking hole 135 to achieve a fixed connection between the liquid storage shell 128 and the outer shell 102 by locking.

[0048] Combination Figure 2 and Figure 15 As shown, in some embodiments, the housing assembly further includes a decorative piece 137, which is fixedly connected to the upper cover 129.
