Description

Technical Field

[0001] This utility model relates to the field of heater technology, specifically to a heater shell structure. Background Technology

[0002] As an indispensable household appliance in winter, heaters quickly raise the indoor temperature through electric heating elements, hot air circulation, or infrared radiation, creating a warm and comfortable living environment for people. Its core component—the heater shell—is not only a "safety barrier" to protect the internal circuits and heating elements, but also undertakes multiple functions such as heat dissipation, heat insulation, and aesthetic design.

[0003] In existing heater casings, a heat dissipation mesh is installed. However, this mesh is currently secured with bolts. When dust accumulates on the mesh, workers often use brushes to clean it. However, brushing can cause fine particles to enter the casing. Therefore, to prevent particle intrusion, the mesh is often disassembled for cleaning. However, disassembly requires removing multiple screws, which is inconvenient and inefficient. Therefore, a new technical solution is needed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a shell structure for a heater to solve the current technical problem of inconvenient quick disassembly.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: design a heater shell structure, including: a shell, a limiting hole is opened on one side wall of the shell, and a suitable filter screen is installed in the limiting hole. The filter screen is used to block impurities in the outside air from entering the inner cavity of the shell.

[0006] Both sides of the outer wall of the filter screen are fixed with limiting shells. Limiting plates are inserted into the openings of the limiting shells. Movable frames are fixedly connected to the outer walls of the limiting plates. A sleeve is provided between the two movable frames. The sleeve is fixedly installed on the outer wall of the shell. The two movable frames are respectively inserted into the inner cavities at both ends of the sleeve. A driving assembly is installed in the inner cavity of the sleeve. The driving assembly is used to drive the movable frames to move.

[0007] Specifically, the filter screen can block impurities from the outside air from entering. Over time, a lot of impurities will accumulate on the filter screen, requiring cleaning. At this time, the drive component can drive the movable frames on both sides to move outward, thereby causing the limit plate to disengage from the limit shell. Thus, the limit shell can be released from its limit, and the filter screen can also be released from its limit. Then, the filter screen can be removed directly, which improves the convenience of operation.

[0008] Preferably, the driving assembly includes a rotating shaft rotatably mounted in the inner cavity of the sleeve. A gear is fixedly fitted on the outer wall of the rotating shaft, and racks mesh on both sides of the outer wall of the gear. A sliding block is fixedly connected to one end of the rack, and the sliding block is fixedly connected to the inner end of the corresponding movable frame. Rotating the rotating shaft can drive the gear to rotate, thereby driving the rack to move, which in turn drives the sliding block to move, thereby driving the movable frame to move, and indirectly driving the limit plate to move, thereby achieving limit locking and release of the limit shell.

[0009] Preferably, one end of the rotating shaft movably passes through the sleeve and is fixedly connected to a rotating block. The outer wall of the rotating block is provided with anti-slip texture. The rotating block allows the gear to be rotated by hand, making the operation convenient and quick.

[0010] Preferably, the outer wall of the movable frame is fitted with a first spring. One end of the first spring is fixedly connected to the inner wall of the sleeve end, and the other end is fixedly connected to the sliding block. When the movable frame moves outward, the sliding block will compress the first spring. Thus, when the first spring is in a compressed state, after the filter screen is installed in the limiting hole, the movable frame is reset under the action of the first spring's counter-thrust force. This allows the limiting insert plate to automatically insert into the inner cavity of the limiting shell, which helps to improve the ease of operation.

[0011] Preferably, one side wall of the limiting insert plate is provided with an inclined surface. When the limiting insert plate is inserted into the limiting shell, the inclined surface fits against the inner wall of the limiting shell for insertion. As the insertion depth increases, the clamping force of the inclined surface on the limiting shell increases, which helps to improve the limiting and clamping effect on the filter screen. In addition, with the damping rubber pad, it helps to improve the stability of the filter screen after installation.

[0012] Preferably, the width of the limiting insert plate is the same as the width of the inner cavity of the limiting shell.

[0013] Preferably, a second spring is fixedly installed on all four sides of the inner wall of the limiting hole. When the filter screen is installed in the limiting hole, it will apply pressure to the four second springs. Specifically, after the filter screen is installed, the second spring is in a compressed state. So when the filter screen is released from the limiting hole, the second spring can push the filter screen to move outward, thereby further improving the convenience of removing the filter screen.

[0014] Preferably, a damping rubber pad is fixedly installed on the inner wall of the filter screen plate. Holes are opened on all four sides of the outer wall of the damping rubber pad. When the filter screen plate is installed in the limiting hole, the damping rubber pad can be used to fit against the inner wall of the limiting hole, thereby making the damping rubber pad pressurized. This helps to improve the fit, avoid the intrusion of dust and impurities in the connection gap, and the fit connection helps to improve the stability after connection.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model can drive the gear to rotate by rotating the rotating block, thereby driving the two racks to move, which in turn drives the movable frame to move, so that the limiting block can be disengaged from the limiting shell, thereby achieving quick disassembly and releasing the filter screen, thus improving the convenience of filter screen assembly and disassembly.

[0017] After the filter screen is released from the limiting block, it can be pushed out of the limiting hole by the pushing force of the second spring, which further improves the convenience of disassembling the filter screen.

[0018] 2. This utility model uses a limiting insert plate to limit the insertion into the inner cavity of the limiting shell. The inner wall of the limiting insert plate has an inclined surface, which fits against the inner wall of the limiting shell for insertion. As the insertion depth increases, the clamping force of the inclined surface on the limiting shell increases, which helps to improve the limiting and clamping effect on the filter screen. Combined with the damping rubber pad, it helps to improve the stability of the filter screen after installation. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0027] Example 1: A heater housing structure, see [link / reference] Figures 1 to 6 The shell (1) includes a limiting hole 11 on one side wall of the shell 1, and a suitable filter screen 12 is installed in the limiting hole 11. The filter screen 12 is used to block impurities in the outside air from entering the inner cavity of the shell 1.

[0028] Limiting shells 13 are fixed on both sides of the outer wall of the filter screen 12. Limiting plates 23 are inserted into the openings of the limiting shells 13. Movable frames 21 are fixedly connected to the outer walls of the limiting plates 23. A sleeve 2 is provided between the two movable frames 21. The sleeve 2 is fixedly installed on the outer wall of the housing 1. The two movable frames 21 are respectively inserted into the inner cavities at both ends of the sleeve 2. A driving assembly is installed in the inner cavity of the sleeve 2. The driving assembly is used to drive the movable frames 21 to move.

[0029] It should be understood that in actual use, the filter screen 12 can block the intrusion of impurities in the outside air. Over time, a lot of impurities will be attached to the filter screen 12, which needs to be cleaned. At this time, the drive component can drive the movable frames 21 on both sides to move outward, thereby causing the limiting plate 23 to disengage from the limiting shell 13. Thus, the limiting shell 13 can be released from its limiting position, and the filter screen 12 can also be released from its limiting position. Then, the filter screen 12 can be removed directly, which helps to improve the convenience of operation.

[0030] Furthermore, in order to enable the filter screen 12 to be quickly removed after the limiting hole 11 is released, a second spring 16 is fixedly installed on each of the four sides of the inner wall of the limiting hole 11. It should be understood that when the filter screen 12 is installed in the limiting hole 11, it will apply pressure to the four second springs 16. Specifically, after the filter screen 12 is installed, the second springs 16 are in a compressed state. Thus, after the filter screen 12 is released from the limiting hole, the second springs 16 can push the filter screen 12 to move outward, thereby further improving the convenience of removing the filter screen 12.

[0031] Furthermore, a damping rubber pad 14 is fixedly installed on the inner wall of the filter screen 12. Holes 15 are opened on all four sides of the outer wall of the damping rubber pad 14. It should be understood that when the filter screen 12 is installed in the limiting hole 11, the damping rubber pad 14 can be used to fit against the inner wall of the limiting hole 11, thereby making the damping rubber pad 14 pressurized, which helps to improve the fit, avoid the intrusion of dust and impurities in the connection gap, and the fit connection helps to improve the stability after connection.

[0032] like Figure 1 and 45. The drive assembly includes a rotating shaft, which is rotatably installed in the inner cavity of the sleeve 2. A gear 27 is fixedly mounted on the outer wall of the rotating shaft. A rack 26 meshes on both sides of the outer wall of the gear 27. A sliding block 25 is fixedly connected to one end of the rack 26. The sliding block 25 is fixedly connected to the inner end of the corresponding movable frame 21.

[0033] It should be understood that the rotating shaft can drive the gear 27 to rotate, thereby driving the rack 26 to move, which in turn drives the sliding block 25 to move, which in turn drives the movable frame 21 to move, and indirectly drives the limit plate 23 to move, thereby achieving limit locking and releasing the limit shell 13.

[0034] Furthermore, one end of the rotating shaft movably passes through the sleeve 2 and is fixedly connected to a rotating block 22. The outer wall of the rotating block 22 is provided with anti-slip texture. It should be understood that the rotating block 22 is designed so that the gear 27 can be rotated by holding the rotating block 22, thus making the operation convenient and quick.

[0035] Furthermore, in order to enable the movable frame 21 to automatically return to its inward position during installation, a first spring 28 is fitted on the outer wall of the movable frame 21. One end of the first spring 28 is fixedly connected to the inner wall of the end of the sleeve 2, and the other end is fixedly connected to the sliding block 25. It should be understood that when the movable frame 21 moves outward, the sliding block 25 will compress the first spring 28. Thus, when the first spring 28 is in a compressed state, after the filter screen 12 is installed in the limiting hole 11, the rotating block 22 is released, and the movable frame 21 returns to its original position under the action of the counter-thrust of the first spring 28. This allows the limiting insert plate 23 to automatically insert into the inner cavity of the limiting shell 13, which helps to improve the ease of operation.

[0036] like Figure 1 and 4 As shown, a bevel 24 is provided on one side wall of the limiting insert plate 23. It should be understood that when the limiting insert plate 23 is inserted into the limiting shell 13, the bevel 24 fits against the inner wall of the limiting shell 13 for insertion. As the insertion depth increases, the bevel 24 provides a greater clamping force to the limiting shell 13, which helps to improve the limiting and clamping effect on the filter screen 12. Combined with the damping rubber pad 14, this helps to improve the stability of the filter screen 12 after installation.

[0037] Furthermore, the width of the limiting insert 23 is the same as the width of the inner cavity of the limiting shell 13, which helps to prevent wobbling in the width direction after the limiting insert 23 is inserted into the limiting shell 13, thereby improving the limiting stability.

[0038] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.

However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
