Description

Technical Field

[0001] This utility model relates to the field of atomization technology, and in particular to a housing assembly and an atomizing device. Background Technology

[0002] Atomizing devices typically consist of many components that require assembly and mating. Before leaving the factory, workers must assemble these parts together. The housing of an atomizing device usually has a snap-fit ​​structure to fasten two housings together. However, existing snap-fit ​​structures typically only provide locking in one direction, making them prone to detachment and damage during drops. To reduce this risk, related technologies often employ additional snap-fit ​​structures. However, for atomizing devices with transparent housings, adding snap-fit ​​structures can negatively impact the device's appearance. Utility Model Content

[0003] The technical problem to be solved by this application is to provide a housing assembly and atomizing device that reduce the risk of buckle detachment during drops and do not affect the appearance of the device.

[0004] In some embodiments, a housing assembly is provided, comprising a first housing and a second housing; the first housing has opposing first surfaces and a second surface, and a mounting groove passing through the first and second surfaces; the second housing has opposing third surfaces and a fourth surface, and a mounting buckle disposed on the third surface, the mounting buckle being configured to fit into the mounting groove, the first surface and the third surface being disposed opposite to each other; the mounting buckle includes a first limiting portion and a second limiting portion, the first limiting portion and the second limiting portion being connected along a third direction; the first limiting portion is configured to engage with the mounting groove to limit the relative displacement of the mounting groove and the mounting buckle in a first direction and a second direction; the second limiting portion is configured to abut against the second surface to limit the relative displacement of the mounting groove and the mounting buckle in the third direction; wherein the first direction, the second direction and the third direction are mutually perpendicular.

[0005] In some embodiments, the mounting groove includes a limiting region and a pre-installation region, wherein the pre-installation region is disposed at one end of the limiting region along the second direction and communicates with the limiting region; wherein the pre-installation region is configured to allow the first limiting part and the second limiting part to pass through the first housing.

[0006] In some embodiments, the limiting region includes a first limiting groove and a second limiting groove, the first limiting portion is configured to engage with the first limiting groove, the second limiting groove is disposed on the side of the first limiting groove away from the pre-installation area and communicates with the first limiting groove; the mounting buckle further includes a third limiting portion, the third limiting portion is disposed on the side of the first limiting portion away from the pre-installation area and connects with the first limiting portion; wherein, the third limiting portion is configured to engage with the second limiting groove.

[0007] In some embodiments, there is an assembly gap between the first limiting groove and the first limiting portion; and / or, there is an assembly gap between the second limiting groove and the third limiting portion.

[0008] In some embodiments, the dimension of the second limiting portion along the first direction is less than or equal to the dimension of the pre-installed area along the first direction; and / or, the projected area of ​​the second limiting portion on the plane formed by the second direction and the first direction is greater than the projected area of ​​the limiting area on the plane formed by the second direction and the first direction.

[0009] In some embodiments, the mounting groove is provided with at least two protrusions disposed opposite to each other, the protrusions protruding relative to the groove wall of the mounting groove; wherein, the at least two protrusions define the mounting groove to define the pre-installation area and the limiting area.

[0010] In some embodiments, each of the protrusions has a first guide slope disposed toward the pre-installed area; the first limiting portion has a second guide slope disposed toward the first guide slope.

[0011] In some embodiments, the distance between the two protrusions along the first direction is smaller than the distance of the first limiting portion along the first direction.

[0012] In some embodiments, a receiving groove is provided on a first surface of the first housing, and a light-transmitting area is provided on the second housing. The receiving groove is configured to accommodate a display screen, and the light-transmitting area is disposed opposite to the receiving groove; and / or, a first fastening portion is further provided on one side of the mounting groove on the first surface, and a second fastening portion is further provided on one side of the mounting buckle on the third surface, wherein the first fastening portion and the second fastening portion are fitted together.

[0029] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0030] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0031] Please see Figures 1 to 3 In some embodiments, an atomizing device is provided, comprising a first housing 1 and a second housing 2. The first housing 1 includes a first surface 11 facing the second housing 2 and a second surface 12 facing away from the second housing 2, and a mounting groove 3 penetrating the first surface 11 and the second surface 12. The second housing 2 includes a third surface 21 facing the first housing 1 and a fourth surface 22 facing away from the first housing 1. The third surface 21 is provided with a mounting buckle 4 adapted to the mounting groove 3. That is, the first surface 11 and the third surface 21 are disposed opposite to each other. The fourth surface 22 is the exposed surface of the atomizing device. The first housing 1 and the second housing 2 can be detachably connected together via the mounting groove 3 and the mounting buckle 4; alternatively, the first housing 1 and the second housing 2 can be assembled together via the mounting groove 3 and the mounting buckle 4 to form a tight fit, which can also be a tight fit that is difficult to disassemble.

[0032] like Figure 3As shown, one of the first housing 1 and the second housing 2 forms a receiving cavity 80, that is, either the first housing 1 or the second housing 2 forms a receiving cavity 80. Relative to the receiving cavity 80, the first surface 11 is disposed further outward than the second surface 12, and the fourth surface 22 is disposed further outward than the third surface 21. The atomizing device also includes an atomizing component (not shown) disposed within the receiving cavity 80. For example, Figure 1 and Figure 2 In the illustrated embodiment, the first housing 1 forms a receiving cavity 80, and the first housing 1 with a mounting groove 3 is used to mount the atomizing component; alternatively, in other embodiments, the second housing 2 may form a receiving cavity 80, and the second housing 2 with a mounting buckle 4 may be used to mount the atomizing component. The atomizing component can store the atomizing matrix and, when energized, can heat and atomize the atomizing matrix to generate an aerosol. Furthermore, the atomizing device also includes a power supply component, which may be simultaneously disposed in the receiving cavity 80. The power supply component is connected to the atomizing component and can form an electrical connection with the atomizing component to provide power to the atomizing component.

[0033] like Figures 2 to 5 As shown, the atomizing device has a first direction, a second direction, and a third direction that are mutually perpendicular. That is, the first and second directions are perpendicular to each other, the first direction and the third direction are perpendicular to each other, and the second direction and the third direction are also perpendicular to each other. Together, the first, second, and third directions constitute a three-dimensional space. Among them, it is possible to... Figures 2 to 4 The directional markers in the diagram serve as direction references: U represents up, D represents down, L represents left, R represents right, B represents back, and F represents forward. The left direction L and the right direction R together form the first direction (left-right direction), the up direction U and the down direction D together form the second direction (up-down direction), and the forward direction F and the back direction B together form the third direction (forward-backward direction).

[0034] like Figure 3 and Figure 4 As shown, the mounting groove 3 includes at least a limiting area 32, and the mounting buckle 4 is locked relative to the mounting groove 3 within the limiting area 32. Wherein, Figure 5 To facilitate observation and differentiation between mounting groove 3 and mounting buckle 4, mounting groove 3 is represented by a solid outline, while mounting buckle 4 is represented by a dashed outline.

[0035] The mounting buckle 4 includes a first limiting part 41 and a second limiting part 42. The first limiting part 41 and the second limiting part 42 are connected along a third direction (front-back direction). Specifically, the second limiting part 42 is connected to the rear side of the first limiting part 41. The first limiting part 41 engages with the mounting groove 3 to limit the relative displacement of the mounting groove 3 and the mounting buckle 4 in the first and second directions. The second limiting part 42 passes through the mounting groove 3 along the third direction, reaches the rear side of the mounting groove 3, and abuts against the second surface 12. When the mounting groove 3 and the mounting buckle 4 have a tendency to move relative to each other along the third direction, the second limiting part 42 is blocked by the second surface 12. Therefore, the relative displacement of the mounting groove 3 and the mounting buckle 4 in the third direction is limited.

[0036] In summary, because the first limiting part 41 and the mounting groove 3 are fitted together, the relative displacement of the mounting groove 3 and the mounting buckle 4 in the second and first directions is restricted. Simultaneously, the second limiting part 42 abuts against the second surface 12, restricting the relative displacement of the mounting groove 3 and the mounting buckle 4 in the third direction. After assembly, the mounting groove 3 and the mounting buckle 4 are simultaneously limited in three different directions, making the fit between them more secure. This locking structure is more robust and can effectively reduce the risk of the buckle detaching when the atomizing device is dropped. Since the mounting buckle 4 is located on the third surface 21 of the second housing 2, and the third surface 21 is opposite to the first surface 11 of the first housing 1, the mounting buckle 4 is shielded by the second housing 2 on the inside facing the first housing 1, and is not exposed, thus not affecting the appearance of the atomizing device.

[0037] Specifically, such as Figure 4As shown, in some embodiments, the limiting region 32 includes a first limiting groove 321 extending along a first direction (left-right direction). The first limiting portion 41 is configured to engage with the first limiting groove 321. Specifically, the first limiting groove 321 includes a first groove extending to the left from the center of the mounting groove 3 and a second groove extending to the right from the center of the mounting groove 3, with the openings of the first groove and the second groove facing each other in the first direction. The groove wall surface of the first limiting groove 321 includes a left side wall, a right side wall, an upper side wall, and a lower side wall. The first groove extending to the left has a left side wall, an upper side wall, and a lower side wall. The left side wall is connected to both the upper and lower side walls, forming a 90° angle between the left side wall and the upper side wall, and a 90° angle between the left side wall and the lower side wall, so that the upper and lower side walls are parallel to each other. Alternatively, the angular relationship between the left, upper, and lower walls is not limited to this; other angles can also be formed between the adjacent walls. Similarly, the second groove extending to the right has a right wall, an upper wall, and a lower wall, with the right wall connected to both the upper and lower walls. When the mounting groove 3 and the mounting buckle 4 tend to move relative to each other in the first direction, the first limiting part 41 is blocked by the left and right walls of the first limiting groove 321; when the mounting groove 3 and the mounting buckle 4 tend to move relative to each other in the second direction, the first limiting part 41 is blocked by the upper and lower walls of the first limiting groove 321. Therefore, the relative displacement of the mounting groove 3 and the mounting buckle 4 in both the first and second directions is limited.

[0038] In some embodiments, the mounting buckle 4 can be disposed on the third surface 21 of the second housing 2 facing the first housing 1. After the first housing 1 and the second housing 2 are assembled, the mounting groove 3 and the mounting buckle 4 are covered by the second housing 2, so that the buckle structure is not exposed and does not affect the appearance of the atomizing device.

[0039] like Figure 4 and Figure 5 As shown, in some embodiments, the mounting groove 3 further includes a pre-installation area 31, which is disposed at one end of the limiting area 32 along a second direction and communicates with the limiting area 32. The pre-installation area 31 is configured to allow the first limiting part 41 and the second limiting part 42 to pass through the first housing 1. The pre-installation area 31 provides pre-installation space for the mounting buckle 4. When the first housing 1 and the second housing 2 are assembled, the mounting buckle 4 is first positioned in the pre-installation area 31, causing the first limiting part 41 and the second limiting part 42 to extend into the mounting groove 3 along a third direction, with the second limiting part 42 passing through the mounting groove 3. Then, the mounting buckle 4 moves along the pre-installation area 31 to the limiting area 32 and engages with the mounting groove 3 for locking.

[0040] like Figure 4 and Figure 5As shown, in some embodiments, the limiting region 32 further includes a second limiting groove 322, which is connected to the first limiting groove 321 and is disposed on the side of the first limiting groove 321 away from the pre-installation region 31. (See reference...) Figure 4 and Figure 5 The second limiting groove 322 is located above the first limiting groove 321. The mounting buckle 4 also includes a third limiting part 43, which is connected to the first limiting part 41 and located on the side of the first limiting part 41 away from the pre-installation area 31. (Reference) Figure 4 and Figure 5 The third limiting part 43 is located above the first limiting part 41. The third limiting part 43 is configured to engage with the second limiting groove 322. Due to potential dimensional errors in the manufacturing process of the first limiting groove 321 and the first limiting part 41, an assembly gap may form between them. This assembly gap can cause the mounting buckle 4 to wobble relative to the mounting groove 3 in the left-right direction. After the third limiting part 43 engages with the second limiting groove 322, the left-right wobble of the mounting buckle 4 and the mounting groove 3 can be further restricted, minimizing the dimensional errors between the first limiting groove 321 and the first limiting part 41, and making the fit between the mounting buckle 4 and the mounting groove 3 more secure.

[0041] As mentioned above, an assembly gap can be provided between the first limiting groove 321 and the first limiting part 41. An assembly gap can also be provided between the second limiting groove 322 and the third limiting part 43. This assembly gap can be 0.05–0.1 mm. The assembly gap between the first limiting groove 321 and the first limiting part 41 is mainly in the first direction (left-right direction). The risk of wobbling caused by this assembly gap can be reduced by the engagement of the third limiting part 43 and the second limiting groove 322. The assembly gap between the second limiting groove 322 and the third limiting part 43 is mainly in the second direction (up-down direction). The risk of wobbling caused by this assembly gap can be reduced by the limiting effect of the upper and lower sidewalls of the first limiting groove 321 on the first limiting part 41. In this way, the risk of wobbling caused by the assembly gap between the mounting buckle 4 and the mounting groove 3 can be eliminated to the greatest extent possible, making the fit between the two very tight and effectively preventing the buckle from disengaging when the atomizing device falls.

[0042] like Figure 4As shown, in some embodiments, the dimension R1 of the second limiting part 42 along the first direction is less than or equal to the dimension R2 of the pre-installation area 31 along the first direction. Therefore, when the mounting buckle 4 is positioned in the pre-installation area 31, the second limiting part 42 can directly pass through the pre-installation area 31 along the third direction, making the positioning of the mounting buckle 4 in the pre-installation area 31 faster. Then, moving the mounting buckle 4 upwards to the limiting area 32 completes the self-locking. In other embodiments, the dimension R1 of the second limiting part 42 along the first direction is greater than the dimension R2 of the pre-installation area 31 along the first direction. In this case, when the mounting buckle 4 is positioned in the pre-installation area 31, the second limiting part 42, due to its larger size, cannot directly blindly pass through the pre-installation area 31 along the third direction. However, by slightly tilting the mounting buckle 4 at a small angle, it can still pass through the pre-installation area 31.

[0043] like Figure 4 As shown, in some embodiments, the projected area of ​​the second limiting part 42 on the plane formed by the second direction and the first direction (i.e., the LRUD plane) is larger than the projected area of ​​the limiting region 32 on the plane formed by the second direction and the first direction. For example, the projected area of ​​the second limiting part 42 on the LRUD plane is larger than the projected area of ​​the first limiting groove 321 and the second limiting groove 322 on the LRUD plane. In this way, since the size of the second limiting part 42 on the LRUD plane is relatively large, after the mounting buckle 4 and the mounting groove 3 are engaged, the second limiting part 42 cannot pass through the limiting region 32 in the reverse direction (forward, F direction), but can only abut against the second surface 12, thereby achieving the limiting of the mounting groove 3 and the mounting buckle 4 in the third direction.

[0044] like Figure 4 and Figure 5 As shown, in some embodiments, the mounting groove 3 has two protrusions 5, each protruding relative to the groove wall of the mounting groove 3, and the two protrusions 5 are arranged opposite each other and spaced apart along a first direction. At least two protrusions 5 define a pre-installation area 31 and a limiting area 32 within the mounting groove 3. Specifically, refer to... Figure 4 and Figure 5 The positioning area 32 is located above the protrusion 5, and the pre-installation area 31 is located below the protrusion 5. The gap formed by the two protrusions 5 along the first direction serves as a transition area for the mounting buckle 4 to move from the pre-installation area 31 to the positioning area 32.

[0045] like Figure 4 and Figure 5As shown, in some embodiments, each protrusion 5 has a first guide slope 51, which faces the pre-installation area 31. A second guide slope 411 is provided on the first limiting portion 41, which faces the first guide slope 51, and the slopes of the second guide slope 411 and the first guide slope 51 are the same. When the mounting buckle 4 moves from the pre-installation area 31 to the protrusion 5, the second guide slope 411 and the first guide slope 51 come into contact; during the process of pushing the mounting buckle 4 from the protrusion 5 into the limiting area 32, the guide slopes play a guiding role, helping the mounting buckle 4 to slide smoothly upward into the limiting area 32, facilitating quick installation. Alternatively, in other embodiments, the slopes of the second guide slope 411 and the first guide slope 51 may be slightly different.

[0046] like Figure 3 As shown, in some embodiments, the dimension R3 of the gap between the two protrusions 5 along the first direction is smaller than the dimension R4 of the first limiting part 41 along the first direction. Therefore, as the mounting buckle 4 moves through the gap formed by the two protrusions 5 along the first direction to the limiting region 32, the first limiting part 41 will be subjected to the squeezing force of the protrusions 5 in the first direction (left-right direction), causing the first limiting part 41 to deform to a certain extent; when the first limiting part 41 moves to the position of the first limiting groove 321, the squeezing force disappears, and the deformation of the first limiting part 41 returns to its original state. Because the first limiting part 41 is relatively large, its lower end abuts against the protrusions 5, and the downward movement trend of the first limiting part 41 is restricted by the protrusions 5, so that the first limiting part 41 is very stably fixed in the first limiting groove 321.

[0047] like Figure 2 As shown, in some embodiments, the first surface 11 also has a receiving groove on one side of the mounting groove 3, which is configured to accommodate the display screen 6. The second housing 2 covers the display screen 6. The second housing 2 has a light-transmitting area, which is arranged opposite to the receiving groove, so the light-transmitting area and the display screen 6 are arranged opposite to each other. The light emitted by the display screen 6 is concentrated in the direction of the light-transmitting area of ​​the second housing 2, and information such as numbers, text, symbols, and patterns can be displayed on the light-transmitting area of ​​the second housing 2. This information can indicate the on / off state, power state, etc. of the atomizing component. Since the second housing 2 covers the display screen 6, the electronic components on the display screen 6 are not all exposed, but information such as numbers, text, symbols, and patterns can be displayed on the second housing 2. Specifically, the second housing 2 can be a black semi-transparent housing, which can be made of materials such as polymethyl methacrylate (PMMA, commonly known as acrylic or plexiglass), polycarbonate (PC), polyethylene terephthalate (PET), acrylic, phenolic resin, etc. Specifically, refer to Figure 2 In the center, the display screen 6 is located on the right side of the mounting slot 3.

[0048] like Figure 2 As shown, in some embodiments, the first surface 11 is further provided with a first fastening portion 71 on one side of the mounting groove 3, and the third surface 21 is further provided with a second fastening portion 72 on one side of the mounting buckle 4. Specifically, refer to Figure 2 In the mounting configuration, the first fastening part 71 is located below the mounting groove 3, and the second fastening part 72 is located below the mounting buckle 4. The first fastening part 71 and the second fastening part 72 are fitted together. One of the first fastening part 71 and the second fastening part 72 is a groove, and the other is a protrusion. The fitting of the groove and the protrusion achieves the fitting connection, thereby further strengthening the connection between the first housing 1 and the second housing 2. Since the first surface 11 and the third surface 21 are the two inner surfaces of the first housing 1 and the second housing 2 facing each other, the first fastening part 71 and the second fastening part 72 are covered by the second housing 2 and will not be exposed, affecting the appearance of the atomizing device.

[0049] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
