Description

Technical Field

[0001] This application relates to the field of aerosol generation equipment technology, specifically to an atomizing core mounting assembly and an aerosol generation device. Background Technology

[0002] In common aerosol generation equipment, the atomizing core is typically connected and fixed to a plastic bracket using an interference fit. Because the atomizing tube sidewall of the atomizing core needs multiple liquid inlet holes, the area with these holes has relatively low strength. When pressing the atomizing core into the mounting holes of the plastic bracket, the operating force is difficult to control, easily causing deformation or breakage of the atomizing tube, leading to product damage, increased production assembly difficulty, and a decrease in product yield. Summary of the Invention

[0003] To address the issues in related technologies where deformation or breakage easily occurs during the pressing operation between the atomizing core and the mounting hole of the mounting bracket, leading to product damage, high assembly difficulty, and reduced yield, this application provides an atomizing core mounting assembly and an aerosol generation device.

[0005] In a further embodiment of this application, the mounting hole includes a first hole segment and a second hole segment connected in the height direction. The first hole segment is located below the second hole segment, and the diameter of the first hole segment is smaller than the diameter of the second hole segment. The diameter of the second hole segment is adapted to the outer diameter of the atomizing tube. The first hole segment is interference-fitted with the outer wall of the corresponding part of the atomizing tube, and the second hole segment contacts the outer wall of the corresponding part of the atomizing tube but does not generate relative pressure.

[0006] In a further embodiment of this application, the aperture of the first aperture segment gradually decreases from top to bottom.

[0007] In a further embodiment of this application, the ratio of the height of the first hole segment to the total height of the mounting hole is not less than 0.9.

[0008] In a further embodiment of this application, the interference fit between the first orifice segment and the corresponding portion of the atomizing tube is in the range of 0.025 mm to 0.035 mm; and / or, the height dimension of the first gap is in the range of 0.15 mm to 0.25 mm.

[0009] In a further embodiment of this application, a duct hole extending along the height direction is provided on the bottom wall of the mounting hole. The duct hole is connected to the atomizing tube so that external airflow can pass through the duct hole and flow into the heating core. The atomizing core also includes a fixing member, which is disposed in the atomizing tube and located below the heating core. The outer circumferential side of the fixing member abuts against the inner sidewall of the atomizing tube. The pin structure of the heating core extends through the fixing member and the duct hole for electrical connection with the power supply component.

[0010] In a further embodiment of this application, a flexible seal is disposed on the top of the mounting bracket, and the flexible seal has a sealing opening corresponding to the mounting hole; the atomizing tube passes through the sealing opening and is interference-fitted with the inner sidewall of the sealing opening.

[0011] In a further embodiment of this application, the top of the mounting bracket has a first slot, which is arranged circumferentially around the mounting hole; the bottom of the flexible seal has a protruding structure, which is arranged circumferentially around the sealing opening, and the protruding structure is inserted into the first slot and seals against the inner wall of the first slot.

[0012] In a further embodiment of this application, the atomizing core mounting assembly further includes: an atomizing mounting tube disposed above the mounting bracket along the height direction, the bottom of the atomizing mounting tube being sealed to a flexible sealing element, and the top of the atomizing mounting tube being used to connect to a nozzle; a liquid suction element disposed on the inner sidewall of the atomizing mounting tube, and the liquid suction element extending through along the height direction; wherein, the atomizing core is disposed in the liquid suction element, and a second liquid inlet hole is provided on the sidewall of the atomizing mounting tube in the area corresponding to the atomizing core.

[0013] An embodiment of the second aspect of this application provides an aerosol generating device, comprising: a housing, the top of which has a nozzle, and the interior of which has a liquid storage chamber for storing an aerosol matrix; an atomizing core mounting assembly as described in any of the first aspects, disposed within the housing, wherein the atomizing core communicates with the liquid storage chamber through a first liquid inlet hole, so that the aerosol matrix in the liquid storage chamber can enter the heating core and be heated; and a power supply assembly disposed within the housing and electrically connected to the heating core for supplying power to the heating core.

[0014] The beneficial effects of the above-mentioned technical solution of this application are as follows:

[0015] According to the above technical solution in this application, by improving and optimizing the structure, by setting a partial hole section of the mounting hole to form an interference fit with the atomizing tube, excessive pressing force is not required during the pressing process. Furthermore, a first gap is reserved at the bottom of the atomizing tube as a buffer space, which can offset the influence of material cumulative tolerance and assembly tolerance on the bottom of the atomizing tube. This effectively prevents the atomizing tube from being squeezed and interfered with the bottom wall of the mounting hole, thereby reducing the force borne by the atomizing tube and preventing deformation or breakage damage at the opening of the atomizing tube due to excessive force. At the same time, it reduces the difficulty of the pressing operation and helps to improve the yield rate of processing and assembly. Attached Figure Description

[0036] The atomizing core mounting assembly provided in this application can be applied in an aerosol generating device to heat the aerosol matrix, thereby atomizing the aerosol matrix to generate aerosol. For ease of description, in the following embodiments, the width direction of the aerosol generating device is taken as the first direction, and the thickness direction of the aerosol generating device is taken as the second direction, and both the first and second directions are perpendicular to the height direction.

[0037] The following describes some embodiments of the atomizing core mounting assembly and aerosol generating device provided in this application, with reference to the accompanying drawings.

[0038] One embodiment of this application provides an atomizer core mounting assembly 100, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the atomizing core mounting assembly 100 includes a mounting bracket 1 and an atomizing core 2. The mounting bracket 1 is used for connection and assembly with the internal structure of the aerosol generating device; the mounting bracket 1 has a mounting hole 11, which is set along the height direction for mounting the atomizing core 2. The atomizing core 2 is located at the top of the mounting bracket 1 and includes a nested atomizing tube 21 and a heating core 22, with the heating core 22 located inside the atomizing tube 21; the atomizing tube 21 is set along the height direction and corresponds to the mounting hole 11, with the bottom of the atomizing tube 21 extending into the mounting hole 11 and forming an interference fit with the mounting section, and in the height direction, a first gap 113 is formed between the bottom end of the atomizing tube 21 and the inner bottom wall of the mounting hole 11, so that the bottom end of the atomizing tube 21 does not directly contact the inner bottom wall of the mounting hole 11. The heating element 22 is located inside the atomizing tube 21 above the mounting hole 11. The side wall of the atomizing tube 21 above the mounting hole 11 has a first liquid inlet hole 211. The heating element 22 corresponds to the first liquid inlet hole 211 so that when applied in an aerosol generating device, the aerosol matrix can pass through the first liquid inlet hole 211 into the heating element 22 and be atomized to generate aerosol under the heating of the heating element 22.

[0039] During the assembly and processing of the atomizing core mounting assembly 100, after the atomizing core 2 is assembled, the bottom of the atomizing core 2 can be pressed into the mounting hole 11 of the mounting bracket 1. Since only a portion of the mounting hole 11 forms an interference fit with the atomizing tube 21, and a first gap 113 is reserved in the height direction as a buffer space, the atomizing tube 21 is pressed smoothly during the pressing process, and it can prevent the bottom of the atomizing tube 21 from being squeezed and interfered with the inner bottom wall of the mounting hole 11 due to the cumulative tolerance of the material and the over-tolerance.

[0040] Under normal circumstances, the bottom end of the atomizing tube is directly inserted into the bottom of the mounting hole and abuts against the inner bottom wall. During the pressing process of inserting the atomizing tube into the mounting hole, since the atomizing tube and the mounting hole adopt an interference fit, a relatively large pressing force needs to be applied. Due to the influence of material cumulative tolerance and assembly tolerance, the atomizing tube and the inner bottom wall of the mounting hole will squeeze each other after abutting, which increases the stress on the atomizing tube. Since the area with the liquid inlet hole on the side wall of the atomizing tube has low strength, it is very easy to cause deformation or breakage at the opening of the atomizing tube under the stress at both ends, resulting in product damage. Therefore, it is difficult to accurately determine the magnitude of the pressing force during the pressing process, which increases the difficulty of the pressing operation and reduces the yield of processing and assembly.

[0041] In this embodiment, the atomizing core mounting assembly 100, through structural improvements and optimizations, forms an interference fit between a portion of the mounting hole 11 and the atomizing tube 21. This eliminates the need for excessive pressing force during the pressing process. Furthermore, a first gap 113 is reserved at the bottom of the atomizing tube 21 as a buffer space, which can offset the impact of cumulative material tolerances and assembly tolerances on the bottom of the atomizing tube 21. This effectively prevents the atomizing tube 21 from being squeezed and interfered with the inner bottom wall of the mounting hole 11, thereby reducing the force borne by the atomizing tube 21 and preventing deformation or breakage at the opening of the atomizing tube 21 due to excessive force. At the same time, it reduces the difficulty of the pressing operation and helps improve the yield rate of processing and assembly.

[0042] It should be noted that in practical applications, the atomizing tube 21 can be made of metal, and the mounting bracket 1 can be made of rigid rubber. The atomizing tube 21 can have one or more first liquid inlet holes 211. Preferably, multiple first liquid inlet holes 211 can be spaced apart circumferentially on the atomizing tube 21. The specific number and size can be set according to actual usage requirements. Furthermore, the structural form of the mounting bracket 1 can be set according to the internal structure of the aerosol generating equipment being assembled.

[0043] In further embodiments of this application, such as Figure 3 and Figure 4As shown, the mounting hole 11 includes a first hole segment 111 and a second hole segment 112, and the first hole segment 111 and the second hole segment 112 are connected along the height direction. The first hole segment 111 is located below the second hole segment 112, and the diameter of the first hole segment 111 is smaller than the diameter of the second hole segment 112. The diameter of the second hole segment 112 is adapted to the outer diameter of the atomizing tube 21. When the atomizing tube 21 is pressed into the mounting hole 11 from above, the atomizing tube 21 first enters the second hole segment 112. Since the diameter of the second hole segment 112 is adapted to the outer diameter of the atomizing tube 21, the atomizing tube 21 does not form an interference fit with the second hole segment 112 at this time. Therefore, a large pressing force is not required, and the atomizing tube 21 can pass through the second hole segment 112 relatively smoothly. As the atomizing tube 21 continues to extend, it enters the first section 111 of the mounting hole 11. Since the diameter of the first section 111 is smaller than that of the second section 112, the atomizing tube 21 forms an interference fit with the first section 111 under the pressure. When the bottom end of the atomizing tube 21 reaches the target position, the first section 111 of the mounting hole 11 and the corresponding part of the atomizing tube 21 form an interference fit, while the second section 112 and the corresponding part of the atomizing tube 21 only contact each other without generating relative pressure. That is, there is no dimensional overlap or gap between the second section 112 and the corresponding part of the atomizing tube 21. Because a first gap 113 is reserved between the bottom end of the atomizing tube 21 and the inner bottom wall of the mounting hole 11, during the pressing process, even if affected by the cumulative tolerance of materials and assembly tolerances, the bottom end of the atomizing tube 21 will not come into contact with the inner bottom wall of the mounting hole 11 and be squeezed against each other. This avoids the upper and lower ends of the atomizing tube 21 being subjected to force simultaneously, thus preventing stress concentration at the opening of the atomizing tube 21, which could lead to deformation or breakage. In addition, when applied in aerosol generating equipment, since the outer surface of the atomizing tube 21 can contact the aerosol matrix, the interference fit between the atomizing tube 21 and the first hole section 111 in the mounting hole 11 can also seal the mounting hole 11, preventing leakage of the aerosol matrix from the mounting hole 11.

[0044] Furthermore, in one embodiment, such as Figure 3 and Figure 4In the example shown, the diameter of the first orifice 111 gradually decreases from top to bottom in the height direction, so that the first orifice 111 forms a conical orifice. The resistance experienced by the atomizing tube 21 gradually increases during the pressing process into the first orifice 111. Correspondingly, the pressing force required in the initial stage of pressing is relatively small, and the pressing force required gradually increases as the atomizing tube 21 is pressed downwards, thus avoiding the atomizing tube 21 constantly bearing a large pressing force during the pressing process. At the same time, the conical orifice shape of the first orifice 111 also guides the atomizing tube 21, making the pressing process of the atomizing tube 21 relatively smooth. Preferably, the diameter of the top of the first orifice 111 is the smallest and is equal to or close to the diameter of the second orifice 112, so that the resistance is reduced when the atomizing tube 21 enters the first orifice 111 from the second orifice 112.

[0045] It is understandable that if the mounting hole 11 adopts a structure with the same aperture and forms an interference fit with the atomizing tube 21, then under the influence of material cumulative tolerance and assembly tolerance, the interference of the atomizing tube 21 is larger towards the bottom of the mounting hole 11. This requires a consistently higher pressing force during the pressing process, and the pressing force required is greater towards the bottom, making it difficult to accurately control the pressing force. This can easily lead to deformation or breakage of the atomizing tube 21 due to excessive pressing force. However, the above-mentioned arrangement in this embodiment satisfies the assembly requirements of the atomizing tube 21 and the mounting hole 11, reduces the difficulty of the pressing operation of the atomizing tube 21, and correspondingly reduces the possibility of damage to the atomizing tube 21 during the pressing process. The specific aperture size of the first hole segment 111 can be set according to the outer diameter of the atomizing tube 21 and the actual assembly requirements.

[0046] Furthermore, in a specific example, such as Figure 3 and Figure 4 As shown, the ratio of the height of the first segment 111 of the mounting hole 11 to the total height of the mounting hole 11 is not less than 0.9. That is, in the mounting hole 11, at least 90% of the segment in the height direction forms an interference fit with the atomizing tube 21 to meet assembly and sealing requirements, prevent insufficient interference fit from affecting the connection strength between the atomizing tube 21 and the mounting bracket 1, prevent loosening during use, and ensure the sealing effect of the mounting hole 11. In addition, since the second segment 112 is located above the first segment 111, the atomizing tube 21 enters the second segment 112 first and then the first segment 111 during the pressing process into the mounting hole 11. The first segment 111 can be used to guide and transition the atomizing tube 21.

[0047] Furthermore, in a specific example, such as Figure 3 and Figure 4As shown, in the mounting hole 11, the interference fit between the first hole segment 111 and the corresponding part of the atomizing tube 21 is in the range of 0.025mm to 0.035mm. Preferably, the interference fit can be 0.03mm, so that the resistance and corresponding pressing force of the atomizing tube 21 during the pressing process are within an appropriate range while meeting the assembly and sealing requirements, so as to avoid the atomizing tube 21 being deformed or broken due to excessive force.

[0048] Furthermore, in a specific example, such as Figure 3 and Figure 4 As shown, in the mounting hole 11, a first gap 113 is formed between the bottom end of the atomizing tube 21 and the inner bottom wall of the mounting hole 11. The height of the first gap 113 is in the range of 0.15mm to 0.25mm. Preferably, the height of the first gap 113 is 0.2mm, so as to reserve sufficient buffer space to offset the influence of material cumulative tolerance and assembly tolerance, avoid the atomizing tube 21 from contacting the inner bottom wall of the mounting hole 11 and generating relative compression. At the same time, it can make full use of the internal space of the mounting hole 11 and avoid space waste caused by the excessive height of the first gap 113, which is conducive to improving the compactness of the overall structure.

[0049] In further embodiments of this application, such as Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, an air guide hole 12 is provided on the bottom wall of the mounting hole 11, extending along the height direction to communicate with the atomizing tube 21. The heating element 22 located in the atomizing tube 21 can maintain communication with the outside through the air guide hole 12. External airflow can pass through the air guide hole 12 and flow into the heating element 22 in the atomizing tube 21 to mix with the aerosol generated at the heating element 22 and carry the aerosol to continue flowing. Correspondingly, the atomizing element 2 also includes a fixing member 23, which is located at the bottom of the atomizing tube 21, that is, below the heating element 22. The circumferential outer wall of the fixing member 23 abuts against the inner wall of the atomizing tube 21, for example, forming an interference fit to form a connection assembly. Correspondingly, the heating element has a pin structure 221, which extends out of the fixing member 23 and through the air guide hole 12 to the bottom of the mounting bracket 1 for electrical connection with the power supply component 52 when applied in an aerosol generating device. The fixing member 23 may have corresponding holes for the pin structure 221 to pass through.

[0050] In further embodiments of this application, such as Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, the atomizer core mounting assembly 100 also includes a flexible seal 3. The flexible seal 3 is located on the top of the mounting bracket 1 and is assembled and connected to the mounting bracket 1. The flexible seal 3 has a sealing opening 30, which corresponds to the mounting hole 11. The atomizing tube 21 of the atomizer core 2 passes through the sealing opening 30 and extends into the mounting hole 11. The outer wall of the atomizing tube 21 and the inner wall of the sealing opening 30 form an interference fit, thereby sealing the mounting hole 11 using the flexible seal 3. The combination of the partial interference fit between the atomizing tube 21 and the mounting hole 11 forms two sealing fits, which further improves the sealing effect on the mounting hole 11. The flexible seal 3 can be made of flexible materials such as silicone.

[0051] Furthermore, in one embodiment, such as Figures 8 to 10 In the example, the top of the mounting bracket 1 is provided with a first slot 13, which is arranged circumferentially around the mounting hole 11 so that the mounting hole 11 is entirely located inside the first slot 13. Correspondingly, the bottom of the flexible seal 3 is provided with a protruding structure 31, which is arranged circumferentially around the sealing opening 30 and is adapted to the first slot 13. The protruding structure 31 is inserted into the first slot 13 and forms a sealing fit with the inner sidewall of the first slot 13, thereby forming a sealing structure around the mounting hole 11 in the circumferential direction, so as to seal the gap between the flexible seal 3 and the mounting bracket 1 in the lateral direction, and at the same time, it can also fix the flexible seal 3 and the mounting bracket 1. Preferably, the first slot 13 adopts Figure 9 The annular slot structure shown in the figure has a raised structure 31. Figure 10 The annular protrusion structure 31 is shown in the figure.

[0052] In further examples of this application, such as Figure 11 and Figure 12As shown, the atomizing core mounting assembly 100 also includes an atomizing mounting tube 41 and a liquid suction member 42. The atomizing mounting tube 41 is located above the mounting bracket 1 and is arranged along the height direction; the bottom of the atomizing mounting tube 41 is sealed to the flexible sealing member 3, and the liquid suction member 42 is disposed inside the atomizing mounting tube 41 and extends through it along the height direction. The atomizing core 2 is disposed in the liquid suction member 42, and a second liquid inlet hole 411 is provided on the side wall of the atomizing mounting tube 41 in the area corresponding to the atomizing core 2. When the atomizing core mounting assembly 100 is applied in an aerosol generating device, the top of the atomizing mounting tube 41 is connected to the nozzle, and the aerosol matrix in the liquid storage chamber can be adsorbed into the liquid suction member 42 through the second liquid inlet hole 411, and then enter the heating core 22 through the first liquid inlet hole 211 of the atomizing core 2, and be heated and atomized to generate aerosol. The liquid-absorbing component 42 can be made of materials such as absorbent cotton and wraps around the atomizing core 2 in the circumferential direction to cover the multiple first liquid inlet holes 211 on the atomizing tube 21. Specifically, in the height direction, the liquid-absorbing component 42 at least covers the top of the atomizing core 2; preferably, such as... Figure 12 In the example shown, the liquid suction element 42 also covers the portion of the atomizing mounting tube 41 located above the atomizing core 2 for adsorbing condensate from the aerosol gas. It should be noted that in practical applications, the number of second liquid inlets 411 can be one or more. Preferably, multiple second liquid inlets 411 can be spaced apart circumferentially on the atomizing mounting tube 41 to improve liquid inlet efficiency. When the height of the atomizing mounting tube 41 is relatively high, such as... Figure 12 In the example shown, multiple liquid suction elements 42 can be spaced apart along the height direction.

[0053] An embodiment of the second aspect of this application provides an aerosol generating device 500, such as... Figure 13 and Figure 14 As shown, the aerosol generating device 500 includes a housing 51, an atomizing core mounting assembly 100 as described in any of the embodiments of the first aspect, and a power supply assembly 52. ​​The housing 51 serves as the mounting base for the aerosol generating device 500, and both the atomizing core mounting assembly 100 and the power supply assembly 52 are housed within the housing 51. A suction nozzle 510 is provided at the top of the housing 51 for the user to perform a suction action; a liquid storage chamber 514 is provided inside the housing 51 for storing the aerosol matrix. The atomizing core 2 of the atomizing core mounting assembly 100 is correspondingly disposed with the liquid storage chamber 514 and can communicate with the liquid storage chamber 514 through a first liquid inlet hole 211, allowing the aerosol matrix to pass through the first liquid inlet hole 211 and enter the heating core 22 inside the atomizing tube 21. The power supply assembly 52 is electrically connected to the heating core 22 to supply power to the heating core 22, enabling the heating core 22 to heat up when energized, thereby heating and atomizing the aerosol matrix to generate aerosol. External air can enter the atomizing tube 21 and mix with the aerosol generated at the heating core 22 to form an aerosol gas, which then flows along the atomizing mounting tube 41 to the mouthpiece 510.

[0054] Furthermore, such as Figure 14 In the example shown, the power supply assembly 52 includes a battery 521 and an electronic control board 522 that are electrically connected. The heating element 22 is electrically connected to the electronic control board 522 via a pin structure 221, so that the electronic control board 522 controls the battery 521 to supply power to the heating element 22. The electronic control board 522 is disposed in the space below the mounting bracket 1, and the battery 521 is disposed above the mounting bracket 1 and electrically connected to the electronic control board 522 via corresponding conductive elements.

[0055] Furthermore, such as Figure 14 In the example shown, housing 51 specifically includes an outer shell 511, an outer shell base 512, an inner shell 513, and a corresponding support structure 5131. The bottom of the outer shell 511 is detachably connected to the outer shell base 512; the inner shell 513 is disposed above the mounting bracket 1 and is sealed to the flexible seal 3; the space between the inner shell 513 and the outer shell 511 forms a liquid storage chamber 514, and the support structure 5131 is disposed in the inner shell 513. The battery 521 and the atomizing mounting tube 41 are both located inside the inner shell 513. The top of the atomizing mounting tube 41 is sealed to the nozzle 510, and the bottom of the atomizing mounting tube 41 is inserted into the second slot 32 on the flexible seal; the battery 521 and the atomizing mounting tube 41 are arranged side by side and supported on the support structure 5131 to maintain a certain distance between the battery 521 and the atomizing mounting tube 41. The support structure 5131 is arranged circumferentially around the mounting hole 11 and forms a liquid guiding cavity 515 between itself and the mounting bracket 1. The liquid guiding cavity 515 is connected to the liquid storage cavity 514, and the second liquid inlet 411 of the atomizing mounting tube 41 is located in the liquid guiding cavity 515, so that the aerosol matrix in the liquid storage cavity 514 can enter the suction element 42 through the liquid guiding cavity 515 and the second liquid inlet 411. The flexible sealing element 3 seals the gap between the mounting bracket 1 and the inner wall of the outer shell 511 to prevent the aerosol matrix in the liquid storage cavity 514 from leaking into the space below the mounting bracket 1. An air guiding cavity 516 is formed below the mounting bracket 1, and the air guiding cavity 516 is connected to the mounting hole 11 through the air guiding hole 12. The outer shell base 512 has a corresponding air inlet, and external air can enter the air guiding cavity 516 through the liquid inlet and be drawn into the atomizing core 2 under the action of suction negative pressure to mix with the generated aerosol matrix and then flow into the nozzle 510.

[0056] The aerosol generating device 500 in this embodiment improves and optimizes the assembly method of the atomizing core 2 and the mounting bracket 1. This eliminates the need for excessive pressing force during the pressing operation between the atomizing tube 21 of the atomizing core 2 and the mounting hole 11. Furthermore, the first gap 113 reserved at the bottom of the atomizing tube 21 serves as a buffer space, offsetting the impact of accumulated material tolerances and assembly tolerances on the bottom of the atomizing tube 21. This effectively prevents extrusion interference between the atomizing tube 21 and the inner bottom wall of the mounting hole 11, thereby reducing the force borne by the atomizing tube 21 and preventing deformation or breakage at the opening due to excessive force. Simultaneously, it reduces the difficulty of the pressing operation, improving the yield rate of the processing and assembly. This solution requires no changes to the housing 51 or other internal structures of the aerosol generating device 500; the atomizing core mounting assembly 100 can be directly replaced in existing products, reducing production costs and facilitating application in existing products. It is easy to implement.

[0057] Furthermore, the aerosol generating device 500 in this embodiment also has all the beneficial effects of the atomizing core mounting assembly 100 in any of the above embodiments, which will not be repeated here.

[0058] In addition, it should be noted that the above is only one of the preferred examples of the aerosol generating device of this application. In practical applications, the internal structure of the aerosol generating device can also be set according to actual usage needs. For example, the power supply component can also be outside the housing and form an independent device so that it can be connected and assembled with the housing to form a complete product. This will not be elaborated further here.

[0059] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
