Description

Technical Field

[0001] This utility model relates to the field of heater technology, and in particular to a heater module and an aging machine. Background Technology

[0002] Heaters are commonly used as the heat source in equipment such as aging machines. In existing technologies, heaters are typically fixed inside the air duct with screws. Due to the installation location and spatial layout, assembly and subsequent maintenance generally require two or more people, resulting in difficulties in heater installation and maintenance, and low work efficiency. Utility Model Content

[0003] Therefore, it is necessary to provide a heater module and aging machine to address the above problems, so as to facilitate the assembly and maintenance of the heater.

[0004] This utility model provides a heater module for installation within an air duct, comprising a guide rail assembly, a limiting assembly, a fixing assembly, and a heater. The fixing assembly is connected to the guide rail assembly and can slide into the air duct in a preset direction or slide out of the air duct in the opposite direction via the guide rail assembly. The fixing assembly has an inserted state and an exited state. The limiting assembly is disposed on the guide rail assembly. In the inserted state, the limiting assembly restricts the fixing assembly from sliding in the preset direction; in the exited state, the limiting assembly restricts the fixing assembly from sliding in the opposite direction. The heater is detachably disposed on the fixing assembly and can move with the fixing assembly.

[0005] In the aforementioned heater module, the fixing component is removably mounted in the air duct via a guide rail assembly. This allows the user to control the fixing component to slide out of the air duct in a preset direction for assembly and maintenance of the heater, improving work efficiency and enabling single-person operation. The limiting component restricts the sliding range of the fixing component within the air duct, preventing it from sliding too far in the preset direction and colliding with the inner wall of the air duct. It also prevents the fixing component from sliding too far in the preset direction and causing the heater to detach. This enhances the stability of the heater module and ensures safe and reliable operation.

[0006] In one embodiment, the guide rail assembly includes a first guide rail and a second guide rail capable of reciprocating relative to the first guide rail in a preset direction. The first guide rail is disposed on the inner wall of the air duct, and the second guide rail is connected to the fixing component.

[0007] This configuration ensures that the second guide rail and the fixing component always slide back and forth in the preset direction, and the guide rail component has a simple structure, making it easy to process and assemble.

[0008] In one embodiment, the limiting component includes a first limiting member, a second limiting member, and a sliding member. The first limiting member and the second limiting member are spaced apart on the first guide rail along a preset direction, and the sliding member is disposed on the second guide rail. In the extended state, the sliding member abuts against the first limiting member, and in the withdrawn state, the sliding member abuts against the second limiting member.

[0009] This design simplifies the structure of the limit component, making it easier to manufacture and assemble.

[0010] In one embodiment, the second guide rail includes a connecting portion and two guide portions respectively connected to both ends of the connecting portion, with the ends of the two guide portions away from the connecting portion respectively connected to the opposite sides of the fixing component; the number of the first guide rails is two, and they are arranged one-to-one with the guide portions, and the guide portions can slide back and forth relative to the first guide rails in a preset direction.

[0011] With this configuration, the two sets of first guide rails and guide parts are arranged opposite each other on both sides of the fixed component, which can counteract the lateral force on the fixed component and reduce the shaking of the fixed component and heater during the sliding process; the connecting part can prevent the guide part from tilting or deviating during the sliding process.

[0012] In one embodiment, the fixing component includes a first sidewall and a second sidewall opposite to each other. The first sidewall is provided with a through hole, and the second sidewall is provided with a U-shaped hole corresponding to the through hole. One end of the heater is provided with a protrusion that can be inserted into the through hole, and the other end is provided with a screw that can be engaged with the U-shaped hole and a nut that is threadedly engaged with the screw.

[0013] This design simplifies the connection between the heater and the mounting components, requiring only the loosening or tightening of the nuts. This facilitates user disassembly and maintenance of the heater and ensures the stability and reliability of the connection between the heater and the mounting components.

[0014] In one embodiment, the number of heaters is multiple, and each heater is arranged at intervals on the cross-section of the air duct; and / or, the fixing assembly includes opposing first sidewalls and second sidewalls, both of which are provided with through holes, and at least one of the first sidewalls and the second sidewalls has a through hole extending to the edge of the sidewall.

[0015] This configuration ensures that all gas passing through the duct can come into contact with the heater, guaranteeing the uniformity of the gas temperature blown out of the duct and preventing localized overheating. The two ends of the heater are fixedly connected to the first and second sidewalls at the through holes to ensure the stability and reliability of the connection between the heater and the fixed assembly.

[0016] In one embodiment, the fixing component includes a mounting member and a fixing member disposed at one end of the mounting member facing the opposite direction of a preset direction. The heater is disposed on the mounting member, and in the extended state, the fixing member is used to fixally connect to the outer wall of the air duct.

[0017] This design prevents the fixing components and heater from accidentally sliding out of the air duct in the opposite direction of the preset direction, thereby ensuring the safety of the heater module in use.

[0018] In one embodiment, the fastener is provided with a wiring hole.

[0019] With this configuration, the heater's cable can extend through the wiring hole into the air duct and connect electrically to external equipment, facilitating user wiring and ensuring that the cable does not interfere with the normal sliding of the fixed components.

[0020] This utility model also provides an aging machine, including a device body and a heater module as described above. The device body is provided with an air duct, and the heater module is disposed in the air duct.

[0021] This setup allows the heater module to regulate the temperature of the gas blown out of the air duct, simulating different high-temperature environments and accelerating the aging process of the test materials or products. Furthermore, the heater module adopts a modular design, which improves the maintainability and compatibility of the heater module.

[0022] In one embodiment, the aging machine further includes at least one fan, the heater module is located on the air outlet side of the fan, the air duct has an air-gathering section located between the air outlet side of the fan and the heater module, at least one sidewall of the air-gathering section is inclined to guide the air generated by the fan to the heater module.

[0023] With this configuration, the fan can increase the airflow rate in the air duct, prevent hot air from accumulating near the heater, make the temperature of the air blown out of the air duct more uniform, and also make the ambient temperature inside the aging machine reach the preset temperature more quickly, thus improving the response speed.

[0038] Heaters are commonly used as the heat source in equipment such as aging machines. In existing technologies, heaters are typically fixed inside the air duct with screws. Due to the installation location and spatial layout, assembly and subsequent maintenance generally require two or more people, resulting in difficulties in heater installation and maintenance, and low work efficiency.

[0039] To solve the above problems, such as Figures 1 to 7 As shown, this utility model provides a heater module and an aging machine to facilitate the assembly and maintenance of the heater.

[0040] like Figures 1 to 2As shown, specifically, the heater module is used to be installed in the air duct 51. The heater module includes a guide rail assembly 1, a limiting assembly 2, a fixing assembly 3, and a heater 4. The fixing assembly 3 is connected to the guide rail assembly 1 and can slide into the air duct 51 in a preset direction or slide out of the air duct 51 in the opposite direction through the guide rail assembly 1. The fixing assembly 3 has an inserted state and an exited state. The limiting assembly 2 is disposed on the guide rail assembly 1. In the inserted state, the limiting assembly 2 restricts the fixing assembly 3 from sliding in the preset direction. In the exited state, the limiting assembly 2 restricts the fixing assembly 3 from sliding in the opposite direction of the preset direction. The heater 4 is detachably disposed on the fixing assembly 3 and can move together with the fixing assembly 3.

[0041] Define the preset direction as the +X direction shown in the figure, and the opposite of the preset direction as the -X direction shown in the figure.

[0042] In the aforementioned heater module, the fixing component 3 is removably mounted in the air duct 51 via the guide rail component 1, allowing the user to control the fixing component 3 to slide out of the air duct 51 in the reverse direction for assembly and maintenance of the heater 4, thereby improving work efficiency and enabling single-person operation. The limiting component 2 is used to limit the sliding range of the fixing component 3 in the air duct 51, preventing the fixing component 3 from sliding too far in the preset direction and colliding with the inner wall of the air duct 51. It also prevents the fixing component 3 from sliding too far in the reverse direction and causing the fixing component 3 and heater 4 to fall off, thereby enhancing the stability of the heater module and ensuring safe and reliable operation.

[0043] like Figure 6 As shown, the fixing component 3 includes a mounting member 31 and a fixing member 32 disposed at the end of the mounting member 31 facing the opposite direction of a preset direction. The heater 4 is disposed on the mounting member 31. In the extended state, the fixing member 32 is used to fixally connect to the outer wall of the air duct 51. The mounting member 31 is used to support the heater 4. In the extended state, the fixing member 32 can be fixedly connected to the outer wall of the air duct 51 by fasteners such as screws and bolts, preventing the fixing component 3 and the heater 4 from accidentally sliding out of the air duct 51 in the opposite direction of the preset direction, thereby ensuring the safety of the heater module in use.

[0044] like Figure 6 As shown, the fixing component 32 is provided with a wiring hole 321. The cable of the heater 4 can extend out of the air duct 51 through the wiring hole 321 and be electrically connected to the external equipment without the need for additional holes to be drilled in the wall of the air duct 51, so as to facilitate the user's wiring, and the cable will not affect the normal sliding of the fixing component 3.

[0045] like Figure 2As shown, in one embodiment, the guide rail assembly 1 includes a first guide rail 11 and a second guide rail 12 capable of reciprocating relative to the first guide rail 11 along a preset direction. The first guide rail 11 is disposed on the inner wall of the air duct 51, and the second guide rail 12 is connected to the fixing assembly 3. Through the cooperation of the first guide rail 11 and the second guide rail 12, it is ensured that the second guide rail 12 and the fixing assembly 3 always reciprocate along the preset direction. Furthermore, the guide rail assembly 1 has a simple structure, facilitating processing and assembly. Specifically, the first guide rail 11 is provided with a groove 111 extending along the preset direction, and the second guide rail 12 is provided with a slider 1221 slidably disposed in the groove 111.

[0046] Of course, in other embodiments, the guide rail assembly 1 may only include a second guide rail 12 connected to the fixing assembly 3, the inner wall of the air duct 51 is provided with a guide groove extending in a preset direction, and the second guide rail 12 is provided with a slider 1221 slidably disposed in the guide groove. Alternatively, the guide rail assembly 1 may also use other linear guide rails such as ball guide rails, cylindrical guide rails, and roller guide rails.

[0047] like Figures 2 to 4 As shown, in one embodiment, the second guide rail 12 includes a connecting portion 121 and two guide portions 122 respectively connected to both ends of the connecting portion 121. The ends of the two guide portions 122 away from the connecting portion 121 are respectively connected to the opposite sides of the fixing component 3. There are two first guide rails 11, which are arranged one-to-one with the guide portions 122. The guide portions 122 can slide back and forth relative to the first guide rails 11 in a preset direction. The two sets of first guide rails 11 and guide portions 122 are arranged opposite to each other on both sides of the fixing component 3, which can counteract the lateral force on the fixing component 3 and reduce the shaking of the fixing component 3 and the heater 4 during the sliding process. The connecting portion 121 connects the two guide portions 122, which can prevent the guide portions 122 from tilting or deviating during the sliding process, thereby further enhancing the stability of the heater module. The end of the guide portion 122 away from the connecting portion 121 can be fixedly connected to the two side walls of the mounting component 31 or the fixing component 32 by fasteners such as screws and bolts, and the two ends of the second guide rail 12 can be fixedly connected to the inner wall of the air duct 51 by fasteners such as screws and bolts.

[0048] Of course, in other embodiments, under the condition that the fixing component 3 can slide stably, the number and arrangement position of the first guide rail 11 can also be adjusted according to the structure of the air duct 51 and the fixing component 3. Specifically, the number of the first guide rail 11 can be 1, 3, 4 or more, and the first guide rail 11 can be set at the bottom of the fixing component 3, and the second guide rail 12 is arranged correspondingly to the first guide rail 11.

[0049] like Figures 2 to 4As shown, in one embodiment, the limiting component 2 includes a first limiting member 21, a second limiting member 22, and a sliding member 23. The first limiting member 21 and the second limiting member 22 are spaced apart along a preset direction on the first guide rail 11, and the sliding member 23 is disposed on the second guide rail 12. In the extended state, the sliding member 23 abuts against the first limiting member 21, at which time the fixing component 3 cannot slide further along the preset direction; in the withdrawn state, the sliding member 23 abuts against the second limiting member 22, at which time the fixing component 3 cannot slide further in the opposite direction along the preset direction. The limiting component 2 has a simple structure, which facilitates processing and assembly. In the illustrated embodiment, the first limiting member 21 and the second limiting member 22 are respectively disposed at both ends of the first guide rail 11, and the sliding member 23 is disposed at one end of the guide portion 122 near the connecting portion 121. Alternatively, the first limiting member 21 and the second limiting member 22 can also be disposed in the middle position of the first guide rail 11 as needed, and the sliding member 23 can also be disposed in the middle position of the guide portion 122 as needed.

[0050] The first limiting member 21 and the second limiting member 22 can be integrally formed with the first guide rail 11, and the sliding member 23 can be integrally formed with the second guide rail 12; or, the first limiting member 21 and the second limiting member 22 can also be fixedly connected to the first guide rail 11 by means of fasteners, welding, adhesive, etc., and the sliding member 23 can also be fixedly connected to the second guide rail 12 by means of fasteners, welding, adhesive, etc.

[0051] Of course, in other embodiments, the first limiting member 21 and the second limiting member 22 may also be disposed on the inner wall of the air duct 51, and the sliding member 23 may also be disposed on the fixing component 3; or, the limiting component 2 may only include the sliding member 23 disposed on the second guide rail 12 or the fixing component 3. In the inserted state and the withdrawn state, the sliding member 23 abuts against the inner wall of the air duct 51 to restrict the fixing component 3 from sliding further.

[0052] like Figure 5 As shown, the mounting component 31 of the fixing assembly 3 includes a first sidewall 311 and a second sidewall 312 facing each other. Both the first sidewall 311 and the second sidewall 312 are provided with through holes 313. At least one of the first sidewall 311 and the second sidewall 312 has a through hole 313 extending to the edge of its respective sidewall. Specifically, "through hole 313 extending to the edge of its respective sidewall" means that the through hole 313 extends radially to the edge of its respective sidewall to form a U-shaped hole 314. Both ends of the heater 4 are fixedly connected to the first sidewall 311 and the second sidewall 312 at the through holes 313, respectively, to ensure the stability and reliability of the connection between the heater 4 and the fixing assembly 3.

[0053] like Figure 5As shown, in one embodiment, the first sidewall 311 has a through hole 313, and the second sidewall 312 has a U-shaped hole 314 corresponding to the through hole 313. One end of the heater 4 has a protrusion 41 that can be inserted into the through hole 313, and the other end has a screw 42 that can be engaged with the U-shaped hole 314 and a nut 43 that is threadedly engaged with the screw 42. When installing the heater 4, first insert the protrusion 41 at one end of the heater 4 into the through hole 313, then insert the screw 42 at the other end of the heater 4 into the U-shaped hole 314, and finally tighten the nut 43 so that the end face of the heater 4 with the protrusion 41 abuts against the first sidewall 311, and the nut 43 abuts against the second sidewall 312. The opposite operation is performed when disassembling the heater 4. In this way, the heater 4 is confined between the first sidewall 311 and the second sidewall 312, ensuring the stability and reliability of the connection between the heater 4 and the mounting part 31. Furthermore, the connection structure between the heater 4 and the mounting component 31 is simple, requiring only the loosening or tightening of the nut 43, which facilitates the user's disassembly, assembly, and maintenance of the heater 4.

[0054] Furthermore, there can be two nuts 43. In the assembled state, the two nuts 43 clamp and fix the two sides of the second sidewall 312 respectively, preventing the screw 42 from accidentally coming out of the U-shaped hole 314, thereby further improving the stability and reliability of the connection between the heater 4 and the mounting part 31.

[0055] In another embodiment, the second sidewall 312 is provided with a through hole 313, and the first sidewall 311 is provided with a U-shaped hole 314 corresponding to the through hole 313; or, both the first sidewall 311 and the second sidewall 312 are provided with corresponding U-shaped holes 314. The connection method of the heater 4 at the through hole 313 and the U-shaped hole 314 is the same as in the above embodiment, and will not be described in detail here.

[0056] Of course, in other embodiments, the heater 4 can also be fixedly connected to the side wall of the mounting component 31 using fasteners such as screws, bolts or clips, as long as the stability and reliability of the connection between the two can be guaranteed. This embodiment of the present invention does not impose specific limitations here.

[0057] like Figure 1 and Figure 5 As shown, there are multiple heaters 4, which are spaced apart on the cross-section of the air duct 51. This ensures that all gas passing through the air duct 51 can come into contact with the heaters 4, guaranteeing the uniformity of the temperature of the gas blown out of the air duct 51 and preventing localized overheating. The number of through holes 313 on the first sidewall 311 and the second sidewall 312 is greater than or equal to the number of heaters 4, allowing the user to adjust the number of heaters 4 installed on the fixing assembly 3 as needed.

[0058] like Figure 1As shown in the illustration, this utility model embodiment also provides an aging machine, including a device body 5 and the aforementioned heater module. The device body 5 is provided with an air duct 51, and the heater module is disposed within the air duct 51. By placing the heater module within the air duct 51, the temperature of the gas blown out from the air duct 51 can be adjusted through the heater module to simulate different high-temperature environments and accelerate the aging process of the test materials or products. This heater module adopts a modular design, which not only enables rapid assembly and maintenance by a single person but also makes it applicable to different models of aging machines, thereby improving the maintainability and compatibility of the heater module.

[0059] Specifically, the equipment body 5 is also provided with an air inlet 52, an air outlet 53 and an installation port 54 connected to the air duct 51. The air inlet 52 and the air outlet 53 are respectively located at both ends of the air duct 51. Gas enters the air duct 51 from the air inlet 52 and is blown out of the air duct 51 from the air outlet 53. The installation port 54 is located between the air inlet 52 and the air outlet 53. The fixing component 3 and the heater 4 are removably installed in the air duct 51 through the installation port 54.

[0060] like Figures 6 to 7 As shown, the aging machine also includes at least one fan 6. A heater module is located on the outlet side of the fan 6. The air duct 51 has an air-concentrating section 511 located between the outlet side of the fan 6 and the heater module. At least one side wall of the air-concentrating section 511 is inclined to guide the airflow generated by the fan 6 to the heater module. The outlet side of the fan 6 is connected to the air inlet 52 of the air duct 51. The fan 6 can increase the gas flow rate within the air duct 51, preventing hot air from accumulating near the heater 4, resulting in a more uniform temperature of the gas blown out of the air duct 51. This also allows the ambient temperature inside the aging machine to reach the preset temperature more quickly, improving the response speed.

[0061] In the illustrated embodiment, there are two fans 6, arranged at an interval. The cross-sectional dimension of the air duct 51 near the air outlet side of the fan 6 is relatively larger than the cross-sectional dimension of the heater module. To ensure a more uniform temperature of the airflow passing through the heater module, both side walls of the air-concentrating section 511 are inclined inward from both sides. In other embodiments, the number of fans 6 can also be set to one, three, four or more, depending on actual needs.

[0062] Of course, this heater module can also be used in other equipment that requires simulating high-temperature environments, and this embodiment of the present invention does not impose any specific limitations.

[0063] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
