Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic atomization equipment technology, and in particular to an anti-overflow adhesive assembly frame and atomization device. Background Technology
[0002] The frame of the atomizing device consists of an outer shell and a support. The support is installed inside the outer shell and is generally fixed to the outer shell using interference fit and adhesive bonding. Interference fit requires the support to be made relatively large to ensure a tight fit between the support and the inner wall of the outer shell. Therefore, the size of the support is difficult to control in actual manufacturing and requires repeated testing to find a suitable size. Furthermore, the tight pressure of the inner wall of the outer shell on the support can cause deformation, potentially damaging the circuit board and power supply. During adhesive bonding, the support and outer shell compress the adhesive, causing it to overflow and spread, sometimes requiring the removal of excess adhesive. Utility Model Content
[0003] The main purpose of this invention is to provide an assembly frame and atomizing device for preventing glue overflow, so as to solve the problem of glue overflow that occurs during the assembly of the frame of the atomizing device in the prior art.
[0004] To achieve the above objectives, this application provides an assembly frame for preventing adhesive spillage, comprising:
[0005] The outer shell has walls that enclose a receiving cavity, and the walls have bonding surfaces for adhesive bonding;
[0006] The bracket has a contact surface that is inserted into the receiving cavity and glued to the connecting surface;
[0007] At least one of the connecting surface and the contact surface is recessed at the adhesive mating point to form an overflow space. Multiple ribs are provided in the overflow space along the assembly direction, and the multiple ribs divide the overflow space into multiple sequentially connected overflow grooves along the assembly direction.
[0008] During the insertion and bonding process of the housing and the bracket, as the bracket is continuously inserted into the receiving cavity, the bracket pushes the overflowing glue in the overflow space into the overflow groove. When one of the overflow grooves is full, it will be injected into the overflow groove at the near end. Or, if the assembly speed is too fast, the overflowing glue will be injected into the overflow groove at the far end. This not only solves the problem of glue overflow, but also expands the bonding area between the bracket and the housing.
[0009] In some embodiments, the top surface of the rib is lower than the notched end face of the overflow space.
[0010] In some embodiments, the height of the plurality of ribs increases sequentially along the assembly direction; or
[0011] The height of the plurality of ribs decreases in the opposite direction to the insert.
[0012] In some embodiments, the volume of the plurality of overflow grooves gradually increases along the assembly direction or gradually decreases along the opposite direction of the insert.
[0013] In some embodiments, the plurality of overflow grooves include a first groove, a second groove, and a third groove disposed along the assembly direction or the opposite direction of the insertion, wherein the first groove and the second groove share a common first groove wall, and the second groove and the third groove share a common second groove wall, and the height of the first groove wall is lower than that of the second groove wall.
[0014] In some embodiments, the plurality of adhesive overflow grooves include a first groove, a second groove, and a third groove disposed along the assembly direction or the opposite direction of the insertion, wherein the volume of the first groove is greater than at least one of the second groove and the third groove.
[0015] In some embodiments, the plurality of adhesive overflow grooves include a first groove, a second groove, and a third groove disposed along the assembly direction or the opposite direction of the insertion, wherein the cross-sectional area of the first groove is greater than at least one of the second groove and the third groove.
[0016] In some embodiments, at least one of the connecting surface and the contact surface protrudes from the plane in which they are located.
[0017] On the other hand, this application provides an atomizing device including the assembly frame for the anti-overflow adhesive in any of the above embodiments.
[0018] Compared with the prior art, this utility model has obvious advantages and beneficial effects: it solves the problem of glue overflow during the assembly process of the atomizing device frame, reduces the glue wiping and scraping process during assembly, thereby reducing the assembly and production cost and making the product more robust and reliable.

[0031] To make the above-mentioned objects, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0032] In the description of this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0033] refer to Figures 1-8 As shown, this application provides an assembly frame for preventing adhesive spillage. The assembly frame includes a housing 10 and a bracket 20. The housing 10 has a receiving cavity 100 defined inside, and the bracket 20 can be inserted into the receiving cavity 100 and connected and fixed to the housing 10.
[0034] Understandably, during assembly, the inner wall 101 of the housing 10 can serve as a bonding surface, and adhesive can be applied to the inner wall 101 of the housing 10 or the bracket 20. Those skilled in the art can, according to actual assembly requirements, provide an adhesive overflow space 202 on the inner wall 101 of the housing 10 or the bracket 20. For example, Figure 2 As shown, the contact surface 200 of the bracket 20 is exposed before assembly, while the connecting surface on the outer shell 10 that mates with the contact surface 200 is located in a relatively concealed position in the receiving cavity 100, and the overflow space 202 is provided on the surface of the bracket 20.
[0035] like Figure 2 As shown, a housing 10 with sides surrounds a receiving cavity 100 with an opening at one end. The depth of the receiving cavity 100 is sufficient to accommodate at least a portion of the support 20. It is understood that the opening can be rectangular, circular, elliptical, rhomboid, etc., and the opening defines the assembly direction of the support 20 within the housing 10. Figure 2 As shown, the white arrow indicates the opening direction of the receiving cavity 100, and the black arrow indicates the assembly direction of the bracket 20, which is opposite to the opening direction.
[0036] refer to Figures 4-8 As shown, the bracket 20 has a contact surface 200 that contacts the inner wall 101 of the housing 10 when inserted into the receiving cavity 100. The contact surface 200 is recessed to form an overflow space 202. Multiple ribs are provided within the overflow space 202 along the assembly direction, dividing the overflow space 202 into multiple overflow channels for accommodating adhesive. The tops of the overflow channels are interconnected. Furthermore, the ribs are shared walls between adjacent overflow channels. When adhesive is injected into the first overflow channel and overflows, the bracket 20, during assembly, contacts the contact surface 200, forcing the overflowed adhesive to flow into the other interconnected overflow channels.
[0037] like Figure 3 As shown, an overflow space 202 is formed by a recess on the contact surface 200 where one side of the bracket 20 contacts the inner wall 101 of the outer shell 10. The overflow space 202 has a downward recessed depth and a notch with a width. Three ribs are provided in the overflow space 202 to divide the overflow space 202 along the assembly direction into a first groove 2010, a second groove 2011, a third groove 2012, and a fourth groove 2013 for receiving overflow. The tops of these grooves are all connected to the overflow space 202.
[0038] In some embodiments, the contact surface 200 of the bracket 20 has a protruding edge 201, and the edge 201 surrounds an internally recessed adhesive overflow space 202 on the contact surface 200. For example... Figure 4 As shown, the plane where the top surface of the protruding edge 201 is located is higher than the plane where the end face of the groove is located, and the side of the edge 201 forms a wall for the overflow of the enclosure adhesive.
[0039] It is understandable that the edge 201 of the overflow space 202 protruding from the contact surface 200 can form the groove wall portion of the first to fourth grooves 2013 mentioned above.
[0040] The height, thickness, and even shape of the ribs can be the same or different from each other. Furthermore, the number of ribs can be increased or decreased according to design requirements based on the art; that is, the adhesive overflow space 202 can be divided into at least two or more grooves. For example, as... Figure 3 As shown, the glue overflow space 202 is provided with 3 ribs, each of which extends perpendicular to the assembly direction. The glue overflow space 202 is divided into four grooves along the assembly direction, which can be defined as the first to fourth grooves 2013 in the opposite direction of assembly. Among them, rib a21 forms the first groove wall shared by the first groove 2010 and the second groove 2011, rib b22 is the second groove wall shared by the second groove 2011 and the third groove 2012, and rib c23 is the third groove wall shared by the third groove 2012 and the fourth groove 2013.
[0041] In some embodiments, the height of the plurality of ribs increases sequentially in the opposite direction of the assembly direction. For example, in combination with... Figures 4-6 As shown, the bracket 20 is inserted into the receiving cavity 100 along the assembly direction indicated by the black arrow. During the assembly process of the bracket 20 and the outer shell 10, the glue pre-injected into the first groove 2010 is squeezed by the contact surface 200 and the inner wall 101 of the outer shell 10. Some of the glue overflows from the first groove 2010 and is forced into the connected second groove 2011. Since the second groove wall is higher than the first groove wall, if the glue is not fully injected into the second groove 2011, the second groove wall will prevent the glue from overflowing into the third groove 2012.
[0042] Understandably, when the excess glue space 202 is constructed on the inner wall 101 of the outer casing 10, the height of the multiple ribs decreases along the assembly direction, and the groove near the side with the lowest rib height is the first groove 2010. During assembly, the glue is first injected into the first groove 2010. When the bracket 20 is inserted into the receiving cavity 100 along the assembly direction, the bracket 20 and the receiving cavity 100 are interference-fitted. The bracket 20 forces the excess glue in the first groove 2010 to be injected into the second groove 2011 along the assembly direction. If the excess glue cannot fill the second groove 2011, the glue cannot pass over the second groove wall and enter the third groove 2012.
[0043] Understandably, when the first groove 2010 is filled, it forms an adhesive surface. Excess adhesive overflowing into other grooves will expand the adhesive surface, but the excess adhesive cannot fill the volume of the remaining grooves. In some embodiments, the volume of the plurality of overflow grooves decreases sequentially along the opening direction of the receiving cavity 100 or increases sequentially along the assembly direction. Figure 3 As shown, the first to fourth grooves 2013, defined along the opening direction of the receiving cavity 100, have volumes that gradually decrease along the opening direction. During assembly, adhesive is injected into the first groove 2010, which has the largest volume, along the opening direction of the receiving cavity 100. When the connecting surface and the contact surface 200 are relatively overlapped, the adhesive is squeezed, and the adhesive in the first groove 2010 diffuses. Due to the limitations of the overflow space 202 and the assembly direction, the overflowing adhesive is forced to flow into the second groove 2011. After the overflowing adhesive fills the second groove 2011, the bonding surface will be expanded. If there is still excess adhesive after filling the second groove 2011, it can continue to be injected into the third groove 2012 and the fourth groove 2013, gradually expanding the bonding surface, and making the connection between the bracket 20 and the outer shell 10 more secure.
[0044] In some embodiments, the plurality of overflow grooves include a first groove 2010, a second groove 2011, and a third groove 2012 defined along the opening direction or assembly direction. For example... Figures 6-8 As shown, a guide channel 2014 is provided between the first groove 2010 and the fourth groove 2013 defined along the opening direction of the receiving cavity 100. The guide channel 2014 is formed on a first groove wall shared by the first groove 2010 and the second groove 2011. The second groove 2011, the third groove 2012, and the fourth groove 2013 are connected by an overflow space 202. When injecting glue into the first groove 2010, if too much glue is injected, the glue will flow into the second groove 2011, preventing it from overflowing into the overflow space 202. For example, the cross-section of the guide channel 2014 can be arc-shaped, rectangular, trapezoidal, etc.
[0045] Understandably, the depth of the guide channel 2014 is h, and the depth of the first groove 2010 is H, where h < H. For example, h ≤ H * 0.1. For example, h ≤ H * 0.7. For example, h ≤ H * 0.95.
[0046] In some embodiments, the plurality of adhesive overflow grooves include a first groove 2010, a second groove 2011, and a third groove 2012 defined along the opening direction or assembly direction of the receiving cavity 100. For example, Figure 3As shown, the overflow groove in the overflow space 202 on the bracket 20 defines a first groove 2010, a second groove 2011, and a third groove 2012 along the opening direction of the receiving cavity 100 on the outer shell 10. The volume of the first groove 2010 is greater than at least one of the second groove 2011 and the third groove 2012.
[0047] For example, the volume of the first groove 2010 is V1, the volume of the second groove 2011 is V2, and the volume of the third groove 2012 is V3, where V1 > V2 > V3. The volume relationship of V1, V2, and V3 can be decreasing.
[0048] For example, the volume of the first groove 2010 is V1, the volume of the second groove 2011 is V2, and the volume of the third groove 2012 is V3, where V1 > V2 = V3.
[0049] In some embodiments, the plurality of adhesive overflow grooves include a first groove 2010, a second groove 2011, and a third groove 2012 defined along the opening direction or assembly direction of the receiving cavity 100. For example, Figure 3 As shown, the glue overflow channels within the glue overflow space 202 on the bracket 20 define a first groove 2010, a second groove 2011, and a third groove 2012 along the opening direction of the receiving cavity 100 on the outer shell 10. The cross-sectional area of the first groove 2010 is larger than at least one of the second groove 2011 and the third groove 2012. For example, the ratio of the cross-sectional areas of the first groove 2010 to the third groove 2012 can be decreasing.
[0050] In some embodiments, the opening end face of the overflow space 202 is located on a first plane, wherein the distance between the opening end faces of the plurality of overflow grooves and the first plane increases sequentially along the opening direction of the aforementioned receiving cavity 100.
[0051] In some embodiments, the opening end face of the overflow space 202 is located on a first plane, wherein the distance between the opening end faces of the plurality of overflow grooves and the first plane decreases sequentially along the assembly direction.
[0052] On the other hand, such as Figures 1-8 As shown, this application provides an atomizing device 1, which includes the anti-overflow adhesive assembly frame in any of the above embodiments.
