DETAILED DESCRIPTION

[0032] The application will be described in further detail below with specific reference being made to the drawings. Like elements are referenced with like numerals throughout the several figures of the drawings. In the following description, numerous specific details are described to provide a thorough understanding of the application. However, it will be apparent to one skilled in the art that the application can be practiced without some or all of these specific details. In other instances, well known process operations have not been described in detail in order to avoid unnecessarily obscuring the application. As used in this application, the term "comprising" or grammatical variants thereof is intended to mean that the applications contain the recited features, but not excluding others. The use of the negative term "not comprising" or grammatical variants thereof is intended to mean that the applications exclude the recited features.

[0033] In addition, the features, operations or characteristics described in the specification can be combined in any suitable manner in various embodiments, and the steps involved in the operations of various embodiments can be sequentially adjusted or modified in a manner that can be readily apparent to those skilled in the art. Therefore, the specification and drawings are only intended to clearly describe one embodiment, and do not mean that the components and / or order are necessary.

[0034] The serial numbers of components in this paper, such as "first", "second", etc., are only used to distinguish the described objects, and do not have any order or technical meaning. The "connection" and "coupling" in this application include direct and indirect connection (coupling) unless otherwise specified.

[0035] Combining two devices with different use functions can achieve complete use functions, for example, in the field of atomizers, as shown in Figure 1 and Figure 2 The atomizing device 100 and the energy supply device 200 connected by magnetic attraction can be combined into an atomizing equipment 1000 with complete use function, wherein the atomizing device 100 can heat and atomize the atomizing substrate to generate aerosol, performing the first use function, and the energy supply device 200 can supply or provide electric energy to the atomizing device 100, performing the second use function, and the two use functions cooperate to form the complete use function.

[0036] The atomization device 100 comprises a first shell 101 and a first magnetic attraction member 102 arranged on the first shell 101, wherein the inside of the first shell 101 is provided with an atomizer such as an atomization core, which can heat an atomization substrate to generate aerosol, and the atomizer is set as a first electronic execution unit; the energy supply device 200 comprises a second shell 201 and a second magnetic attraction member 202 arranged on the second shell 201, wherein the inside of the second shell 101 is provided with a power supply structure such as a power supply unit, and the power supply unit is set as a second electronic execution unit; the first shell 101 and the second shell 201 can be connected by the mutual magnetic attraction of the first magnetic attraction member 102 and the second magnetic attraction member 202, that is, the power supply unit can provide or supplement the electric energy required for heating the atomization core. The first magnetic attraction member 101 and the second magnetic attraction member 201 can both be magnet blocks, or either of them is a magnet block and the other is a metal block that can be magnetically attracted by a magnet.

[0037] In order to realize the provision or supplement of electric energy from the energy supply device 200 to the atomization device 100 after the connection of the first magnetic attraction member 102 and the second magnetic attraction member 202, a first electric connection member 103 is arranged on the first shell 101, and a second electric connection member 203 is arranged on the second shell 201, and the first electric connection member 103 and the second electric connection member 203 can be in contact after the connection of the first shell 101 and the second shell 201, thereby realizing the conduction function.

[0038] Mounting grooves are arranged at corresponding positions on the first shell 101 and the second shell 201, and the first magnetic attraction member 102 and the second magnetic attraction member 202 can be respectively mounted into the mounting grooves of the corresponding shells. In the related art, a protruding rib is arranged on the groove side wall of the mounting groove, which can realize interference fit connection with the corresponding magnetic attraction member. However, due to the influence of the fit tolerance between the magnetic attraction member and the protruding rib of the mounting groove, the magnetic attraction member is easily detached from the mounting groove when the interference fit force with the protruding rib is too small, and the groove side wall of the mounting groove is deformed under stress when the interference fit force with the protruding rib is too large, and even the first shell 101 or the second shell 201 is cracked under excessive stress.

[0039] At the same time, since the interference fit cannot guarantee that the magnetic attraction member will not be detached for a long time, glue needs to be added in the mounting groove, and the magnetic attraction member is bonded and connected with the groove side wall and the bottom wall of the mounting groove after the glue is cured. However, the amount of added glue cannot be completely quantified, and in the case of too much glue, the glue is easy to overflow the mounting groove, which needs to be wiped off again, affecting the appearance and assembly efficiency of the product.

[0040] To solve the above problems, the shell and the atomization device are provided, the magnetic attraction piece and the installation groove are gap-fitted, and the magnetic attraction piece is fixed in the installation groove in a plug-in manner through the fixing piece, so that excessive stress between the magnetic attraction piece and the installation groove is prevented to cause the shell to crack, and the magnetic attraction piece can be stably fixed in the installation groove.

[0041] In the following embodiments, the atomization device is an atomization device with an atomizer or a power supply device capable of providing power or supplementing power to the atomizer, and the atomization device and the power supply device combined can form an atomization product with complete use function. The shell can be a first shell of the atomization device or a second shell of the power supply device, and the magnetic attraction piece can be a first magnetic attraction piece arranged on the first shell or a second magnetic attraction piece arranged on the second shell.

[0042] Referring to Figures 3-10 The shell provided by the application is applied to an atomization device, and the shell includes a shell body 10, a magnetic attraction piece 20, and a fixing piece 30.

[0043] The shell body 10 is a plastic shell structure made in an injection molding manner. The shell body 10 has a connecting side 11, which is a side surface of a first shell 101 of an atomization device 100 and a second shell 201 of a power supply device 200 connected to each other. The connecting side 11 is provided with an installation groove 12, which is a groove-shaped structure recessed inward from the connecting side 11, so that the slot opening of the installation groove 12 is flush with the surface of the connecting side 11.

[0044] The magnetic attraction piece 20 is gap-fitted in the installation groove 12, that is, the radial dimension of the magnetic attraction piece 20 is smaller than the circumferential dimension of the installation groove 12, so that the gap-fitted connection mode is achieved.

[0045] As shown in Figure 5 and Figure 10 The installation groove 12 is surrounded by a groove bottom 125, a first groove side wall 126, and a second groove side wall 127. The same side of the first groove side wall 126 and the second groove side wall 127 is connected to the groove bottom 125, or both extend from the circumferential side of the groove bottom 125 to surround the installation groove 12. Figure 5 and Figure 10 The cross-sectional shape of the magnetic attraction piece 20 is a racetrack type, and the cross-sectional shape of the installation groove 12 surrounded by the groove bottom 125, the first groove side wall 126, and the second groove side wall 127 is also a racetrack type, so as to facilitate the installation of the magnetic attraction piece 20. Of course, in other embodiments, the cross sections of the installation groove 12 and the magnetic attraction piece 20 can also be rectangular or other shapes, which can be selected according to actual needs.

[0046] In some embodiments, after the magnetic attraction piece 20 is placed in the installation groove 12, the magnetic attraction piece 20 does not protrude from the slot opening 128 of the installation groove 12 (as Figure 10As shown, this ensures that the surface of the connecting side 11 is flat, so that the surface of the first housing 101 of the atomizing device 100 fits better after it is connected to the second housing 201 of the power supply device 200.

[0047] The fastener 30 is inserted into the magnetic 20 to fix the magnetic 20 in the mounting groove 12 and prevent the magnetic 20 from coming out of the mounting groove 12.

[0048] In some embodiments, the fastener 30 may be disposed inside the mounting groove 12, or may be installed in the mounting groove 12 in other ways and fixed in the mounting groove 12 by means of plug-in engagement with the magnetic attractor 20. For details on the specific structure of the fastener 30, please refer to the following embodiments.

[0049] Since there is a clearance fit between the magnetic 20 and the mounting groove 12, the magnetic 20 will not exert stress on the mounting groove 12, thus preventing the shell body 10 from cracking. At the same time, the magnetic 20 can be fixed in the mounting groove 12 by means of the fastener 30, preventing the magnetic 20 from coming out of the mounting groove 12.

[0050] like Figures 3-5 As shown, this is one structural form of the fastener 30. The fastener 30 includes a positioning post 31. One end of the positioning post 31 is connected to the bottom of the mounting groove 12, and the positioning post 31 extends from the bottom of the mounting groove 12 to the opening 128 of the mounting groove 12. The magnetic suction member 20 is provided with a positioning hole 21. The positioning post 31 is inserted into the positioning hole 21, and the positioning post 31 and the positioning hole 21 are interference fit, thereby fixing the magnetic suction member 20 in the mounting groove 11.

[0051] In some embodiments, two positioning posts 31 are provided at the bottom of the mounting groove 12. The two positioning posts 31 are symmetrically arranged about the center of the mounting groove 12. Correspondingly, two positioning holes 21 are provided on the magnetic suction member 20. The two positioning holes 21 are symmetrically arranged about the center of the magnetic suction member 20, thereby ensuring that the magnetic suction member 20 can be clearance-fitted with the mounting groove 12.

[0052] Of course, in other embodiments, it is sufficient that the positioning of the positioning post 31 and the positioning hole 21 can ensure the clearance fit between the magnetic suction member 20 and the mounting groove 12. Here, the setting method of the positioning post 31 and the positioning hole 21 is not limited.

[0053] In some embodiments, one end of the positioning post 31 can be connected to the bottom of the mounting groove 12 by means of threaded connection, bonding, fastener fixation, etc., that is, the positioning post 31 and the mounting groove 12 are separate structures.

[0054] In some embodiments, the positioning column 31 and the bottom of the mounting groove 12 are integrally formed, for example, the shell is made by injection molding to integrally form the fixing member 30 at the bottom of the mounting groove 12.

[0055] Referring to Figures 7-10 As shown, the fixing member 30 includes a plug 32, the first slot side wall 126 of the mounting groove 12 is provided with a first pin hole 121, the magnetic member 20 is provided with a plug hole 22, the plug hole 22 is coaxially arranged with the first pin hole 121 after the magnetic member 20 is mounted in the mounting groove 12, the first pin hole 121 provided through the first slot side wall 126 of the mounting groove 12 is in communication with the external space of the shell body 10, the plug 32 can be conveniently inserted into the first pin hole 121, and the plug 32 inserted into the first pin hole 121 can be inserted into the plug hole 22 of the magnetic member 20 mounted in the mounting groove 12, so that the plug 32 is inserted into the first pin hole 121 and the plug hole 22. In some embodiments, the plug 32 and the plug hole 22 are in interference fit, so that the magnetic member 20 can be fixed in the mounting groove 12.

[0056] It can be understood that the interference fit between the plug 32 and the plug hole 22 can fixedly connect the plug 32 and the magnetic member 20, the first pin hole 121 can limit the plug 32 in the radial direction, thereby preventing the magnetic member 20 from being pulled out of the mounting groove 12 from the slot opening 128 of the mounting groove 12.

[0057] In some embodiments, the plug hole 22 can be a blind hole, and only the interference fit between the part of the plug 32 inserted into the plug hole 22 and the plug hole 22 is required.

[0058] As Figure 10 shown, the plug 32 is a hollow metal column, which can be deformed during insertion into the plug hole 22, so as to be connected in interference fit with the plug hole 22.

[0059] In some embodiments, the hollow metal column can be made of copper, iron or other metal materials. Since copper has better ductility than iron and is not easy to be magnetized by a magnet, the hollow metal column is usually made of copper to facilitate the installation of the plug 32 into the plug hole 22 of the magnetic member 20.

[0060] Referring to Figure 8 and Figure 10As shown, the second slot side wall 127 of the mounting slot 12 is provided with a second pin hole 122, wherein the first slot side wall 126 and the second slot side wall 127 of the mounting slot 12 are opposite side walls, the second pin hole 122 is coaxially arranged with the first pin hole 121, the insertion hole 22 is arranged through the magnetic attraction member 20, the insertion pin 32 is inserted into the first pin hole 121, the insertion hole 22 and the second pin hole 122, the insertion pin 32 is in clearance fit with the first pin hole 121 and the second pin hole 122, which can prevent the insertion pin 32 from generating excessive stress with the first pin hole 121 and the second pin hole 122 to cause the shell body 10 to crack.

[0061] Continuing to refer to Figure 10 As shown, the insertion pin 32 has a first section 321, a second section 322 and a third section 323 connected head to tail, the first section 321 is inserted into the first pin hole 121, the second section 322 is inserted into the insertion hole 22, and the third section 323 is inserted into the second pin hole 122, the radial dimension of the second section 322 is greater than the radial dimension of the first section 321 and the radial dimension of the second section 322, so that the insertion pin 32 can be in interference fit with the insertion hole 22 when the radial dimensions of the first pin hole 121, the insertion hole 22 and the second pin hole 122 are consistent or substantially consistent, while the insertion pin 32 is in clearance fit with the first pin hole 121 and the second pin hole 122.

[0062] In order to facilitate the insertion of the insertion pin 32 into the first pin hole 121, the insertion hole 22 and the second pin hole 122, in some embodiments, the third section 323 is provided as a tapered section, wherein the radial dimension of the third section 323 gradually decreases away from the second section 322, thereby forming a tapered section, which can at least generate a clearance with the first pin hole 121 and the insertion hole 22 during the insertion process, and facilitate the insertion of the insertion pin 32 into the first pin hole 121, the insertion hole 22 and the second pin hole 122.

[0063] When the insertion pin 32 has a consistent or substantially consistent radial dimension, the hole diameter of the insertion hole 22 is smaller than the hole diameter of the first pin hole 121, and the hole diameter of the insertion hole 22 is greater than the hole diameter of the second pin hole 122, which can also enable the insertion pin 32 to be in interference fit with the insertion hole 22, while the insertion pin 32 is in clearance fit with the first pin hole 121 and the second pin hole 122.

[0064] In order to further improve the fixing effect between the magnetic attraction member 20 and the mounting slot 12, as shown Figure 5 As shown, the bottom of the mounting slot 12 is provided with a glue storage groove 123 and a glue discharge hole 124, the glue storage groove 123 is used to store adhesive to bond the magnetic attraction member 20 and the bottom of the mounting slot 12, and the glue discharge hole 124 is used to discharge the adhesive overflowing from the glue storage groove 123.

[0065] The way of sticking the magnetic member 20 in the installation groove 12 by the adhesive can be adapted to the implementation of the fixing member 30 as the positioning column 31, and can also be adapted to the implementation of the fixing member 30 as the latch 32. Since the connection mode of interference fit between the positioning column 31 and the positioning hole 21 on the magnetic member 20 cannot be maintained for a long time, the positioning hole 21 of the magnetic member 20 has the problem of loosening with the positioning column 31, which leads to the magnetic member 20 being easy to be pulled out of the installation groove 12, therefore, the groove bottom of the installation groove 12 in the implementation of the fixing member 30 as the positioning column 31 is preferably provided with the glue storage groove 123 and the glue discharge hole 124. As for the implementation of the fixing member 30 as the latch 32, since the first section 321 of the latch 32 is limited in the radial direction of the latch 32 by the action of the first pin hole 121, and the third section 323 is limited by the action of the second pin hole 122, and the magnetic member 20 is limited by the limiting action of the first groove side wall 126 and the second groove side wall 127 of the installation groove 12, therefore, the magnetic member 20 will not have the problem of being pulled out of the installation groove 12, and further, the installation groove 12 in the implementation of the fixing member 30 as the latch 32 can not be provided with the glue storage groove 123 and the glue discharge hole 124.

[0066] In some embodiments, as shown in Figure 6 The glue discharge hole 124 penetrates the groove bottom of the installation groove 12, in other words, after the adhesive filled in the glue storage groove 123 overflows when the magnetic member 20 is installed in the installation groove 12, the adhesive will be discharged through the glue discharge hole 124, and the overflowed adhesive will be discharged into the inside of the shell body 10, the adhesive is not easy to overflow from the slot opening of the installation groove 12 to the outside of the installation groove 12, and further, the step of cleaning the overflowed adhesive is not needed or reduced, and the production efficiency of the product is further improved.

[0067] It should be noted that the content of the adhesive filled in the glue storage groove 123 can be determined after multiple glue injection, and therefore, generally, the content of the adhesive filled in the glue storage groove 123 can basically not overflow or overflow a small amount after the magnetic member 20 is installed in the installation groove 12, and the overflowed adhesive will not affect other internal components after being discharged into the inside of the shell body 10 through the glue discharge hole 124 due to the small amount.

[0068] The application also provides an atomization device, which is described in detail with reference to Figure 1 and Figure 2As shown, the atomization device is an atomization device 100 with an atomizer or a functional device 200 capable of providing power or supplementing power to the atomizer, which includes the shell described in the above embodiments, which can be a first shell 101 of the atomization device 100, or a second shell 201 of the power supply device 200, and the first shell 101 and the second shell 202 can be connected by the first magnetic attraction member 102 and the second magnetic attraction member 202 in a magnetic attraction manner. In some embodiments, the first magnetic attraction member 102 and the second magnetic attraction member 202 provided on the first shell 101 and the second shell 202 are fixed in the mounting groove 12 by the fixing member 30, and the gap between each magnetic attraction member and the corresponding mounting groove can prevent the problem of shell cracking caused by excessive stress.

[0069] For the specific structure and features of the shell, please refer to the above embodiments, which will not be repeated here.

[0070] The atomization device provided in the embodiment further includes an electronic execution unit arranged inside the shell body 10. The electronic execution unit can be an atomizer capable of heating and atomizing an atomization substrate to generate aerosol, or a power supply unit capable of providing power or supplementing power to the atomizer.

[0071] Of course, in other embodiments, it is not limited to the above two devices capable of achieving atomization function and power supply or power supplement, but also to two devices capable of achieving other use functions, which are not limited here.

[0072] As described above, in the shell and atomization device provided in the present application, the magnetic attraction member and the mounting groove are gap-fitted, so that the magnetic attraction member does not generate stress on the mounting groove, thus avoiding the problem of shell cracking, and the magnetic attraction member can be fixed in the mounting groove by the fixing member to prevent the magnetic attraction member from being detached from the mounting groove.

[0073] The above application of specific examples to the present application is only used to help understand the present application and does not limit the present application. For those skilled in the art to which the present application belongs, according to the idea of the present application, a number of simple deductions, deformations or substitutions can be made.
