Description

Technical Field

[0001] This utility model relates to the field of electrothermal film technology, specifically a detachable electrothermal film heating module. Background Technology

[0002] An electric heating film module is a device that converts electrical energy into heat energy. It boasts advantages such as rapid heating, precise temperature control, and energy efficiency, and is widely used in various fields. The electric heating film is the core component of the heating module, typically composed of conductive ink, metal current-carrying strips, and an insulating polyester film. When current passes through the conductive ink, heat is generated, thus achieving the heating function. An outer square PVC box is used to protect the electric heating film and insulation layer, preventing damage from external forces and moisture intrusion.

[0003] Chinese patent CN217985434U discloses a high-safety electrothermal film heating module, including a protective plate. The upper surface of the protective plate has a mounting groove. Above the mounting groove is an insulation plate, above the insulation plate is a heat insulation film layer, and above the heat insulation film layer is a graphene electrothermal chip. Above the graphene electrothermal chip is a capacitor shielding layer, above the capacitor shielding layer is a platinum film, and above the platinum film is a flame-retardant plate.

[0004] This patent allows water to be drained from the flame-retardant board by setting multiple water channels, and the waterproof membrane prevents water from seeping into the flame-retardant board, thereby preventing short circuits in the heating film. The flame-retardant board also plays a flame-retardant role, thus effectively improving the safety performance of the heating film module. Although it solves the safety problem of the heating film to a certain extent, the overall sealed structure makes it inconvenient to replace components later, and maintenance is relatively difficult. Therefore, a detachable heating film module is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a detachable electric heating film module, which has the advantages of good flexibility and easy disassembly, and solves the problem of inconvenient maintenance caused by the integrated structure of the electric heating film module.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a detachable electric heating film heating module, comprising a housing and a protective cover plugged and fixed to the right side of the housing, wherein a heating component is slidably connected inside the housing, and the protective cover is provided with two sets of fixing components for limiting the position of the heating component on one side inside the housing.

[0007] The heating assembly includes a storage box that is slidably connected inside the outer shell. Several heating rods are fixed inside the storage box. Limiting grooves for use with the fixing assembly are opened on both the front and rear sides of the storage box. Limiting plates are fixed inside the limiting grooves. A limiting wedge is fixed on the side of the limiting plate near the inner wall of the outer shell.

[0008] The fixing assembly includes a return spring fixed to the inner wall of the housing, a locking bottom rod fixed to the right side of the return spring, a connecting rod slidably connected inside the limiting groove, a connecting wedge block for fixing the connecting rod fixed to the side of the protective cover near the connecting rod, and an adjusting nut threadedly connected to the left side of the housing.

[0009] The top wall of the outer casing has a corrugated groove for heat transfer, and the right side of the outer casing has an opening. The protective cover is embedded in the opening and a sealing ring is fixed to the surface of the cover near the outer casing.

[0010] The limiting wedge has an inclined surface on the side near the protective cover for limiting the connecting rod, and the back of the connecting rod is slidably connected to the limiting plate.

[0011] The locking base rod and the connecting rod are Z-shaped structures that are adapted to each other, and the side of the locking base rod away from the limiting plate is slidably connected to the inner wall of the outer shell.

[0012] The locking base rod has several limiting protrusions fixed on the side near the limiting plate, and the connecting rod has several limiting slots on the side away from the limiting plate that cooperate with the protrusions.

[0013] The end of the connecting rod near the protective cover has a wedge opening for engaging the connecting wedge block, and the connecting wedge block and the connecting rod are slidably connected.

[0014] The reset spring has a support rod inside that abuts against the adjusting nut, and the end of the support rod away from the adjusting nut is fixedly installed with the locking base rod.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] 1. This detachable electric heating film heating module, by pulling the protective cover out from the side of the outer shell, moves the connecting wedge and connecting rod. The friction between the connecting rod and the limiting wedge drives the limiting plate and the storage box to move. At the same time, the return spring is stretched. When the connecting wedge moves to the outside of the outer shell, it pushes the protective cover to slide vertically, so that the connection between the connecting wedge and the connecting rod is released. The protective cover can then be removed, and the storage box can be pulled out, achieving the purpose of quick disassembly.

[0017] 2. This detachable electric heating film module features a corrugated groove on the outer shell surface to facilitate internal heat dissipation and improve heat transfer efficiency. A sealing ring is provided between the protective cover and the outer shell to prevent external solid and liquid impurities from entering the interior. At the same time, the connecting base rod works with the connecting plug rod to fix the connecting wedge block. The connecting wedge block is limited by the opening of the outer shell and cannot slide up and down on the side of the connecting plug rod. The return spring pulls the connecting wedge block to lock the protective cover on the side of the outer shell. The protective cover simultaneously abuts against the storage box, thus forming an overall fixed structure. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 5 In this embodiment, a detachable electric heating film heating module includes a housing 1 and a protective cover 2 that is plugged into and fixed on the right side of the housing 1. A heating component 3 is slidably connected inside the housing 1. The protective cover 2 is provided with two sets of fixing components 4 that limit the position of the heating component 3 on one side inside the housing 1.

[0026] Please see Figures 2 to 3In this embodiment, the heating component 3 includes a storage box 31 that is slidably connected inside the outer shell 1. Several heating rods 32 are fixed inside the storage box 31. Limiting grooves 33 are provided on both the front and rear sides of the storage box 31 to cooperate with the fixing component 4. A limiting plate 34 is fixed inside the limiting groove 33. A limiting wedge 35 is fixed on the side of the limiting plate 34 near the inner wall of the outer shell 1.

[0027] It should be noted that the heating rod 32 is composed of conductive ink, metal current-carrying strips and insulating polyester film, which is existing technology and will not be elaborated on here.

[0028] In this embodiment, the top wall of the outer shell 1 is provided with a wave groove for heat transfer, and the right side of the outer shell 1 is provided with an opening. The protective cover 2 is embedded in the opening and a sealing ring is fixed on the side surface near the outer shell 1.

[0029] Please see Figure 2 , Figure 3 and Figure 5 In this embodiment, the fixing component 4 includes a return spring 41 fixed to the inner wall of the outer casing 1, a locking bottom rod 42 fixed to the right side of the return spring 41, a connecting rod 43 slidably connected inside the limiting slide groove 33, a connecting wedge block 44 for fixing the connecting rod 43 fixed to the side of the protective cover 2 near the connecting rod 43, and an adjusting nut 45 threadedly connected to the left side of the outer casing 1.

[0030] In this embodiment, the limiting wedge 35 has an inclined surface on the side near the protective cover 2 for limiting the connecting rod 43, and the back of the connecting rod 43 is slidably connected to the limiting plate 34.

[0031] It should be noted that there is a certain degree of friction between the connecting rod 43 and the limiting plate 34, and the limiting plate 34 can be moved by pulling the connecting rod 43.

[0032] In this embodiment, the locking bottom rod 42 and the connecting rod 43 are mutually compatible Z-shaped structures. The side of the locking bottom rod 42 away from the limiting plate 34 is slidably connected to the inner side wall of the outer shell 1. Several limiting protrusions are fixed on the side of the locking bottom rod 42 near the limiting plate 34. Several limiting slots for use with the protrusions are opened on the surface of the connecting rod 43 away from the limiting plate 34.

[0033] The engagement between the locking base rod 42 and the connecting rod 43 is achieved by setting a limiting protrusion and a limiting groove. The limiting wedge 35 presses the connecting rod 43 closer to the locking base rod 42, making the engagement between the two more stable.

[0034] It should be noted that the side where the locking base rod 42 and the connecting rod 43 engage is a plate-like structure. When the connecting rod 43 is inserted, the limiting wedge 35 will squeeze the connecting rod 43 to cause a certain degree of deformation, making the connecting rod 43 closer to the locking base rod 42 relative to the other end.

[0035] In this embodiment, the end of the connecting rod 43 near the protective cover 2 has a wedge opening that matches the connecting wedge block 44, and the connecting wedge block 44 and the connecting rod 43 are slidably connected.

[0036] In this embodiment, the return spring 41 has a support rod inside that abuts against the adjusting nut 45, and the end of the support rod away from the adjusting nut 45 is fixedly installed with the locking bottom rod 42.

[0037] By providing a support rod inside the adjusting nut 45, rotating the adjusting nut 45 will abut against the locking base rod 42, replacing the return spring 41 to support the locking base rod 42, so that the connecting rod 43 cannot push the locking base rod 42 to move when it is inserted.

[0038] All electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0039] The working principle of the above embodiments is as follows:

[0040] (1) The locking base rod 42 is pulled by the return spring 41. Under the synchronous limiting action of the limiting wedge 35 and the limiting plate 34 on the side of the locking base rod 42, the limiting groove on the side of the connecting rod 43 nests with the limiting protrusion on the side of the locking base rod 42, so that the connecting rod 43 and the locking base rod 42 achieve stable engagement. When the protective cover 2 is installed, the adjusting nut 45 needs to be rotated in advance to push the locking base rod 42 to move a certain distance, so that the return spring 41 is stretched in advance. After the protective cover 2 is embedded in the shell 1, after the adjusting nut 45 is unscrewed, the restoring force of the return spring 41 can pull the locking base rod 42, the connecting rod 43 and the connecting wedge 44 to move into the shell 1 as a whole, so that the protective cover 2 is tightly attached to the surface of the shell 1, and the sealing effect is achieved.

[0041] (2) Pull the protective cover 2 out from the side of the outer shell 1. The protective cover 2 moves laterally by pulling the connecting rod 43 through the connecting wedge 44. Due to the pressure of the limiting wedge 35, the engagement between the connecting rod 43 and the locking bottom rod 42 is still present. When the wedge opening of the connecting wedge 44 and the connecting rod 43 moves to the outside of the outer shell 1, the protective cover 2 is moved vertically to release the connection between the connecting wedge 44 and the connecting rod 43. At this time, the storage box 31 can be pulled out to achieve disassembly.

[0042] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
