Description

Technical Field

[0001] This application relates to the field of medical device technology, specifically to a control component mounting structure and an ablation gun. Background Technology

[0002] In the field of medical devices, handheld treatment devices (such as ablation guns) typically integrate control components to operate the various functions of the device. These control components generally include a control circuit board, a button structure mounted on it, and a cable connection structure for transmitting signals from the control circuit board to the device's main unit.

[0003] In existing technologies, the connection methods between control circuit boards and external cables present numerous problems. A common solution is to directly solder the external cables to the control circuit board. However, in medical device manufacturing, this soldering operation places extremely high demands on the cleanliness, temperature, and humidity of the production environment, as well as the skills of the operators, resulting in low production efficiency and high manufacturing costs. Furthermore, the cables at the solder joints are highly susceptible to fatigue fracture due to repeated bending or external tension, severely impacting the reliability and lifespan of the equipment.

[0004] To address these issues, some designs employ flexible printed circuit boards (FPCBs) as a bridge between the control circuit board and external cables. However, due to the inherent flexibility of the FPCB and its low tensile and bending strength, when the external cable is pulled, the tensile force is directly transmitted to the connection point between the flexible and rigid FPCBs, causing the copper foil at that location to repeatedly bend and eventually break due to fatigue. Summary of the Invention

[0005] The present invention aims to provide a control component installation structure and ablative gun that facilitates efficient production and effectively improves the protection of cables from damage to internal circuitry due to tension.

[0006] To solve the above-mentioned technical problems, the present invention provides a control component mounting structure, comprising: Install the frame; The control circuit board is fixed on the mounting frame; An adapter board, separately disposed from the control circuit board, is fixed with an electrical connector for pluggable connection with an external cable; and a flexible connection line, one end of which is electrically connected to the control circuit board and the other end of which is electrically connected to the adapter board. The mounting frame is provided with an elastic holding member, and the outer periphery of the adapter plate is covered with a buffer layer. The elastic holding member presses against the outer surface of the buffer layer to detachably fix the adapter plate to the mounting frame, so that the elastic deformation of the elastic holding member and the buffer layer can absorb the external force acting on the adapter plate. Optionally, the adapter plate includes a fixed section and an adapter section disposed adjacent to each other. The fixed section is connected to the flexible connection line, and the electrical connector is welded and fixed to the adapter section. The buffer layer integrally covers the outer periphery of the electrical connector, the fixed section, and the adapter section, so that the buffer layer forms a stepped surface at the adjacent position of the fixed section and the adapter section. The elastic holding member presses against the buffer layer outside the fixed section and is spaced apart from the stepped surface; and / or, The buffer layer is a heat shrink tubing.

[0007] Optionally, the mounting frame has a protruding post, and the elastic holding member includes an elastic buckle extending outward from the outer periphery of the protruding post.

[0008] Optionally, the protrusion is configured as a stud, so that the mounting frame can be screwed to the housing via the stud.

[0009] Optionally, the mounting frame is further provided with a limiting guide structure for guiding and assisting the adapter plate in fixing to the mounting frame during installation.

[0010] Optionally, the limiting guide structure includes a limiting plate and two limiting blocks. The limiting plate is spaced apart from the protrusion in the lateral direction, and the end side of the limiting plate away from the mounting frame has a first guide slope extending inclined towards the protrusion. The two limiting blocks are disposed below the elastic holding member and are spaced apart in the lateral direction. The limiting plate, the protrusion, and the two limiting blocks together enclose and define an installation space. The adapter plate can be inserted into the installation space from the side where the limiting plate is located under the guidance of the first guide slope. Each of the limiting blocks has a second guide slope on the side facing the other limiting block. The distance between the two second guide slopes gradually decreases from top to bottom. The lower end of the buffer layer has two guide mating surfaces that are arranged opposite each other in the lateral direction. The two guide mating surfaces extend inward from top to bottom and slide in a corresponding manner with the two second guide slopes.

[0011] Optionally, the mounting frame includes a first frame and a second frame, wherein the first frame and the second frame are snapped together and fixed. The first frame extends in the vertical direction, the control circuit board, the adapter board and the flexible connection line are installed on the front side of the first frame, the rear side of the first frame is used to install the heating coil, the second frame extends in the front-back direction, and the upper side of the second frame is used to fix the ejection mechanism of the puncture needle and the volute.

[0012] Optionally, the rear end of the second frame is provided with a first opening slot, the first opening slot being used to pass through a first pipe and an electrical wire connected to the ejection mechanism, the first pipe being in communication with the volute.

[0013] Optionally, the external cable is welded to the end of the coil winding leading from the heating coil to form a welded end, and the welded end is covered with an adhesive heat-shrink tubing; or, The first frame includes an upper frame and a lower frame arranged sequentially from top to bottom. The lower frame is inclined downward and backward relative to the upper frame. The control circuit board is arranged side by side on the front side of the upper frame, and the lower end of the control circuit board extends to the front of the lower frame. The adapter plate is fixed on the front side of the lower frame.

[0014] To solve the above-mentioned technical problems, the present invention provides an ablation gun, including the control component mounting structure as described above.

[0015] In the embodiments provided by this invention, the control component mounting structure transforms the existing "cable soldering" process into a standardized "connector plugging and unplugging" operation by setting an adapter board separate from the control circuit board and fixing an electrical connector on the adapter board. This significantly reduces the stringent requirements for the cleanliness of the production environment, significantly improves assembly efficiency, reduces product manufacturing costs, and also facilitates subsequent maintenance and replacement of the control components.

[0016] More importantly, this invention achieves detachable fixation of the adapter plate by setting elastic clamping members on the mounting frame, covering the outer periphery of the adapter plate with a buffer layer, and pressing the elastic clamping members against the outer surface of the buffer layer. In particular, when the external cable is subjected to external force, the impact force generated by the pull is effectively absorbed and buffered by the elastic deformation of the buffer layer and the elastic clamping members, thereby significantly reducing the stress transmitted to the flexible connection line. This effectively improves the technical problem of flexible connection line breakage caused by cable pulling, and greatly enhances the product's impact resistance and long-term operational reliability.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0021] It should be noted that in the description of this invention, the terms "first," "second," etc., are used only for distinguishing descriptions and should not be construed as indicating or implying relative importance. Furthermore, the terms "comprising," "having," and any variations thereof are intended to cover non-exclusive inclusion. In the description of this invention, unless otherwise expressly specified and limited, the terms "installed," "connected," "linked," "fixed," etc., should be interpreted broadly. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0022] In the description of this invention, it should be understood that the terms "front," "rear," "upper," and "lower," indicating orientation or positional relationships, are defined based on the extension direction of the puncture needle 200 when the ablation gun 1000 is in normal use. Specifically, the direction in which the puncture needle 200 extends to perform the treatment action is "front," and the opposite direction is "rear." When the handle of the ablation gun 1000 is held, the direction that is approximately perpendicular to the front-back direction and points upwards towards the device is "up," and the opposite direction is "lower." These directional terms are used only to simplify the description and more clearly express the relative positions and assembly relationships between the components, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the invention.

[0023] Please see Figures 1 to 8 This invention provides an ablation gun 1000, including a control component mounting structure 100. The ablation gun 1000 is a medical device that uses hot steam or other media to ablate human tissue. It has a housing 800, which forms the external outline of the ablation gun 1000 and houses and supports its internal functional modules. A handle is provided on the housing, and the handle has a button structure. The button structure is an operating component for the user to operate the ablation gun 1000. The user controls the various functions of the ablation gun 1000 by pressing the button 21 on the button structure.

[0024] The control component mounting structure 100 includes a control circuit board 20 and a mounting frame 10, with the control circuit board 20 detachably mounted on the mounting frame 10. A button 21, exposed outside the housing 800, is located on the control circuit board 20 at a position corresponding to the button structure. When the user presses the button 21 on the housing handle, the corresponding circuit on the control circuit board 20 is triggered, thereby generating a corresponding control signal.

[0025] In an alternative embodiment, such as Figures 4 to 6 As shown, the mounting frame 10 includes a first frame 11 and a second frame 12. The rear side of the first frame 11 is used to mount a heating coil 500, which is formed by winding a coil wire 501. The heating coil 500 is used to heat the medium flowing through it to generate steam. The control circuit board 20 is mounted on the front side of the first frame 11. The second frame 12 extends in the front-rear direction, and its upper side is used to fix the ejection mechanism 300 and the volute 400 of the puncture needle 200. The puncture needle 200 is used to puncture human tissue and deliver steam to the target location. The rear end of the puncture needle 200 is connected to a steam source via a hose 201. The ejection mechanism 300 is used to control the ejection and retraction of the puncture needle 200. The volute 400 delivers and recovers cooling and flushing fluid, such as saline solution, to the human tissue through a first conduit 401 and a second conduit 402 connected to it.

[0026] Please continue reading. Figures 2 to 5 The present invention also provides a control component mounting structure 100, which includes a mounting frame 10, a control circuit board 20, an adapter board 30, and a flexible connection line 40. The mounting frame 10, serving as the carrier of the entire control component, is typically made of plastic or metal material with a certain structural strength. It is used to fix the control component mounting structure 100 as a whole onto the housing 800 of equipment such as an ablation gun 1000, and to provide a mounting base for other components.

[0027] The control circuit board 20 is fixed to the mounting frame 10. The control circuit board 20 is a circuit board integrating control circuitry and electronic components. One or more sensing elements can be installed on it to receive operation signals from the button 21 and transmit the processed signals externally. The control circuit board 20 can be a conventional rigid printed circuit board to provide sufficient support strength for installing the button 21 and withstanding the pressing force. The adapter board 30 is separate from the control circuit board 20; that is, the adapter board 30 and the control circuit board 20 are two independent components, not directly connected structurally, but separated by a distance. The adapter board 30 itself is also made of a rigid printed circuit board to provide reliable mechanical strength. An electrical connector 33 is fixed on the adapter board 30, which is used to enable pluggable connection with the external cable 600. The electrical connector 33 can be any standardized connector suitable for signal transmission, such as a pin header socket, FPC connector, USB connector, etc. Electrical connection between the control component mounting structure 100 and the steam therapy unit can be completed by connecting the electrical connector 33 to the corresponding plug on the external cable 600. This transforms the process of soldering cables one by one into a standardized plug-in operation, significantly reducing manufacturing difficulty and avoiding the problems of increased production costs and low production efficiency caused by soldering operations failing to meet the stringent environmental requirements of medical device manufacturing.

[0028] One end of the flexible connection line 40 is electrically connected to the control circuit board 20, and the other end is electrically connected to the adapter board 30. The flexible connection line 40, also known as the FPC, is composed of a bendable insulating substrate and conductive lines printed on it, and can be bent freely within a certain range. In this application, the flexible connection line 40 serves as the only electrical and physical connection bridge between the control circuit board 20 and the adapter board 30, eliminating the rigid connection between the two rigid components and thus physically isolating the force transmission path.

[0029] Crucially, the mounting frame 10 is equipped with an elastic retaining member 111, and the outer periphery of the adapter plate 30 is covered with a buffer layer (not shown in the figure). The elastic retaining member 111 presses against the outer surface of the buffer layer to detachably fix the adapter plate 30 to the mounting frame 10. Through this structure, when the external cable 600 is subjected to external force, the impact force generated by the pulling action is effectively absorbed and buffered by the elastic deformation of the buffer layer and the elastic retaining member 111 as it passes through, thereby significantly reducing the internal stress that would otherwise be directly pulled on the flexible connection line 40. This design significantly reduces the transmission of external force to the flexible connection line 40, allowing the elastic deformation of the elastic retaining member 111 and the buffer layer to absorb the external force acting on the adapter plate 30, effectively preventing the flexible connection line 40 from breaking due to repeated stress.

[0030] In an optional embodiment, the elastic holding member 111 may be a spring sheet or buckle integrally extended from the mounting frame 10, or it may be a separately installed spring clip or elastic pressure block, etc. The buffer layer may be an elastic sleeve fitted on the adapter plate 30, or it may be an elastic coating applied or pasted to its surface.

[0031] The control component mounting structure 100 provided in this embodiment separates the control circuit board 20 from the adapter board 30 and bridges them with a flexible connection line 40. Simultaneously, a flexible constraint and fixing structure consisting of an elastic holding member 111 and a buffer layer is provided at the adapter board 30. This achieves convenient plug-and-play connection of cables, significantly improving product production and maintenance efficiency and reducing production costs. Furthermore, it successfully constructs an external force absorption and isolation mechanism, significantly reducing the impact of external force on the flexible connection line 40, and significantly improving the impact resistance and long-term operational reliability of the control component.

[0032] Based on the previous embodiment, the adapter plate 30 includes a fixed section 31 and an adapter section 32 disposed adjacent to each other. That is, the fixed section 31 and the adapter section 32 are directly adjacent and connected, and they can be integrally formed, i.e., made of the same rigid circuit board. A flexible connection line 40 is connected to the fixed section 31, and an electrical connector 33 is soldered and fixed to the adapter section 32. A buffer layer integrally covers the outer periphery of the electrical connector 33, the fixed section 31, and the adapter section 32. Since the electrical connector 33 protrudes from the surface of the adapter section 32, the buffer layer forms a stepped surface at the adjacent point of the fixed section 31 and the adapter section 32. An elastic clamping member 111 clamps onto the buffer layer outside the fixed section 31 and is spaced apart from the stepped surface. Thus, on the one hand, the fixed section 31 is only composed of a buffer layer and a relatively thin substrate, which facilitates a tight clamping fit of the elastic clamping member 111, while the adapter section 32 has a larger thickness, thus increasing the structural strength of the electrical connector 33. On the other hand, this structural design allows the relatively thick elastic holding member 111 and the electrical connector 33 to be laid flat, resulting in a smaller overall thickness of the control assembly and easier assembly. The buffer layer is preferably a heat-shrink tubing, which, after being heated and shrunk, tightly wraps around the adapter plate 30 and the electrical connector 33 thereon, naturally forming the stepped surface. The heat-shrink tubing itself is elastic and flexible, effectively buffering the holding force and preventing wear caused by hard contact, while also providing additional electrical insulation protection.

[0033] Optionally, the buffer layer can be made of materials such as polyolefin, i.e., insulating tubing that can shrink radially when heated. In this embodiment, a heat-shrinkable sleeve of appropriate inner diameter is fitted around the outer periphery of the adapter plate 30, and then heat-treated to tightly cover the outer surface of the adapter plate 30. The heat-shrinkable sleeve itself has a certain degree of elasticity and flexibility, which can effectively buffer the direct pressing force of the elastic holding member 111 on the adapter plate 30, preventing hard contact between the two from causing wear on the surface of the adapter plate 30 or wear due to vibration. At the same time, the heat-shrinkable sleeve can also provide additional electrical insulation protection to prevent accidental short circuits between exposed solder joints or wires on the adapter plate 30 and the mounting frame 10. In optional embodiments, the buffer layer can also be made of other materials, such as elastic rubber sleeves, silicone coatings, or elastic gaskets bonded to the surface of the adapter plate 30. This embodiment achieves buffer protection and electrical insulation of the adapter plate 30 in a simple and low-cost manner by using heat-shrinkable sleeves as a buffer layer, further improving the operational reliability of the structure.

[0034] Based on the above embodiments, a protruding post 112 is provided on the mounting frame 10. The protruding post 112 can be a plastic post integrally injection molded with the mounting frame 10. The elastic holding member 111 includes an elastic buckle extending outward from the outer periphery of the protruding post 112. The protruding post 112 serves as a lateral limiting structure for the adapter plate 30, while the elastic buckle can make full use of the space around the protruding post 112, sharing the same area on the mounting frame 10 with the protruding post 112, making the overall structure of the control component mounting structure more compact. The elastic buckle extends from the outer periphery of the protruding post 112, forming a cantilever-like structure, with its free end used to press against the adapter plate 30 covered with a buffer layer. When it is necessary to disassemble the adapter plate 30, the free end of the elastic buckle can be moved to open it, releasing the constraint on the adapter plate 30. In optional embodiments, the elastic buckle can be integrally molded with the protruding post 112 and the mounting frame 10, or it can be installed and fixed on the protruding post 112 as an independent component. This embodiment integrates the elastic holding member 111 with the protruding post 112 for fixing the frame, reducing the need for additional fixing structures and making the overall structure of the mounting frame 10 simpler and more compact. It is also easier to operate and improves assembly efficiency.

[0035] In an optional embodiment, the control component can be screwed to the housing 800 using a fastener spaced apart from the protrusion 112. In this embodiment, the protrusion 112 itself can be a stud with a metal nut embedded inside, or a threaded hole can be directly formed in the plastic column. By passing a screw through the outside or inside of the housing 800 and locking it to the protrusion 112, the entire control component mounting structure 100 can be securely fixed to the equipment. By integrating the elastic retaining member 111 with the protrusion 112, which serves as the fixing structure for the control component, the need for additional fixing structures is reduced, making the structure of the mounting frame 10 simpler and more compact, while also facilitating operation and improving assembly efficiency.

[0036] Furthermore, the mounting frame 10 is also provided with a limiting guide structure 113, which is used to guide and assist the adapter plate 30 in fixing to the mounting frame 10 during installation. The function of the limiting guide structure 113 is to guide the adapter plate 30 into the installation position along a preset path during assembly, and after installation, it works together with the elastic holding member 111 to constrain the adapter plate 30 from multiple directions, preventing it from shifting or loosening during use. The limiting guide structure 113 may include ribs, baffles, protrusions, etc. protruding from the mounting frame 10, forming an installation space that matches the shape of the adapter plate 30.

[0037] In an optional embodiment, the limiting guide structure 113 can be disposed on both sides and / or at the end of the insertion path of the adapter plate 30, and its surface can be provided with guide slopes or rounded corners to facilitate the smooth insertion of the adapter plate 30. Preferably, as Figure 3 , Figure 5 and Figure 8 As shown, the limiting and guiding structure 113 includes a limiting plate 1131 and two limiting blocks 1132. The limiting plate 1131 is spaced apart from the protrusions 112 in the lateral direction, where lateral direction refers to the direction parallel to the surface of the mounting frame 10. The end side of the limiting plate 1131 away from the mounting frame 10 has a first guide slope 1133 extending inclined towards the protrusions 112. The two limiting blocks 1132 are located below the elastic holding member 111 and are spaced apart in the lateral direction. The limiting plate 1131, the protrusions 112, and the two limiting blocks 1132 together enclose and define an installation space, and the adapter plate 30 can be inserted into the installation space from the side where the limiting plate 1131 is located under the guidance of the first guide slope 1133.

[0038] During assembly, the adapter plate 30 is pushed into the installation space from the side where the limiting plate 1131 is located, in a direction that is transverse or at an angle of less than 30 degrees to the transverse, towards the protrusion 112. Since the limiting plate 1131 is provided with a first guide slope 1133, during the pushing process, the first guide slope 1133 guides the adapter plate 30 gradually towards the protrusion 112, ensuring it accurately enters the predetermined installation position. Each limiting block 1132 has a second guide slope 1134 on the side facing the other limiting block 1132. The distance between the two second guide slopes 1134 gradually decreases along the insertion direction of the adapter plate 30, that is, the opposing inner surfaces of the two limiting blocks 1132 form an inverted "V" shape opening, narrowing towards the bottom. Correspondingly, the lower end of the adapter plate 30 also has two guide mating surfaces that are arranged opposite each other in the transverse direction. These two guide mating surfaces extend downward and inward, respectively, and slide in contact with the two second guide inclined surfaces 1134. In other words, the lower end of the adapter plate 30 forms a wedge-shaped structure that matches the gradually narrowing space between the two limiting blocks 1132.

[0039] When the adapter plate 30 is pushed into the installation space, its lower guide mating surface contacts and slides against the second guide ramp 1134 on the limiting block 1132. After being snapped in place, during normal use, under the pulling action of the external cable 600, the lateral squeezing force of the limiting block 1132 on the adapter plate 30 gradually increases, generating reliable friction between the two. This design, which uses friction generated by a gradually contracting space to assist in fixing the adapter plate 30, allows the adapter plate 30 to achieve stable positioning and initial fixation simply through the insertion action itself, without any additional operation. Subsequently, the elastic holding member 111 presses the adapter plate 30 from above, forming a final reliable constraint.

[0040] This embodiment achieves automatic alignment upon insertion and frictional force to assist in fixing by the coordinated work of the limiting plate 1131, the limiting block 1132 and the guide mating surface on the adapter plate 30. This significantly improves assembly efficiency and enhances fixing reliability without additional operation. In conjunction with the elastic holding member 111, multiple constraints are formed, making the fixing of the adapter plate 30 more stable.

[0041] Based on the above embodiments, the mounting frame 10 includes a first frame 11 and a second frame 12, which are snap-fitted together. Through this snap-fit ​​connection, the first frame 11 and the second frame 12 can be quickly and reliably assembled without the need for screws or other additional fasteners, thus improving production efficiency and reducing the number of parts. The first frame 11 extends vertically, and the control circuit board 20, adapter board 30, and flexible connection line 40 are mounted on the front side of the first frame 11. The rear side of the first frame 11 is used to mount the heating coil 500. Here, "front" and "rear" refer to their relative usage state. By arranging the control components and the heating coil 500 on opposite sides of the first frame 11, a reasonable functional partitioning is achieved, avoiding mutual interference between the control circuit and the heating coil 500, and making full use of the limited internal space. The second frame 12 extends longitudinally, and its upper side is used to fix the ejection mechanism 300 of the puncture needle 200 and the volute 400. The ejection mechanism 300 is a device that drives the puncture needle 200 to move in and out; for example, it can be a push-pull electromagnet. The volute 400 is a structural component used to guide the endoscope and circulate cooling water. Fixing the ejection mechanism 300 and the volute 400 to the second frame 12 allows the control-related components and the execution-related components to be spatially independent and do not interfere with each other, facilitating separate assembly and maintenance.

[0042] In an optional embodiment, the snap-fit ​​fixing between the first frame 11 and the second frame 12 can be achieved by the cooperation of elastic buckles and slots, or by using structures such as barbs and locks. The specific extension direction of the two frames can be adjusted according to the actual situation of the internal space of the equipment, and is not limited to "up and down" or "front and back" in a strict sense.

[0043] In this embodiment, by designing the mounting frame 10 as a snap-fit ​​first frame 11 and a second frame 12, which respectively carry different types of functional modules, modular assembly is achieved, which significantly simplifies the manufacturing process, improves assembly efficiency, and provides a clear spatial division for each functional module inside the equipment, which is conducive to reducing the overall size of the machine.

[0044] Preferably, the first frame 11 includes an upper frame and a lower frame arranged sequentially from top to bottom, that is, the upper frame is located at the top and the lower frame is located at the bottom, and the two are directly connected or integrally formed. The lower frame is inclined downward and backward relative to the upper frame, that is, while the lower frame extends downward, it also gradually tilts backward, so that the first frame 11 presents a bent shape in the side view, where the upper and lower parts are not in the same vertical plane. The control circuit board 20 is located on the front side of the upper frame, and the lower end of the control circuit board 20 extends to the front of the lower frame. That is, the main body of the control circuit board 20 is attached to the front side of the upper frame, but its lower end extends beyond the junction of the upper and lower frames, continuing to extend downward to the corresponding position in front of the lower frame, and the adapter plate 30 is fixed to the front side of the lower frame.

[0045] Through the above structural design, the lower frame divides the internal cavity of the ablation gun 1000 housing 800 into two relatively independent spaces, front and rear. The space located at the front of the lower frame is used to install the adapter plate and to route the flexible connection line 40. This space is relatively spacious and free from interference from other moving parts or heating elements, allowing the flexible connection line 40 to be arranged in a naturally relaxed state, avoiding damage due to compression or excessive bending. The space located at the rear of the lower frame is used to house the heating coil 500. This space is effectively isolated from the front wiring space by the lower frame, ensuring that the heat and electromagnetic field generated by the heating coil 500 will not directly affect or interfere with the flexible connection line 40 or its transmitted signals. The tilt angle between the upper and lower frames can be adjusted according to the specific layout of the internal space of the housing.

[0046] This embodiment designs the first frame as a combination of an upper frame and an inclined lower frame. On the one hand, it makes full use of the limited space inside the ablation gun handle, rationally partitioning the control circuit board 20, adapter board 30, flexible connection line 40, and heating coil 500, resulting in a compact and orderly overall layout. On the other hand, the physical partition formed by the lower frame effectively protects the flexible connection line 40 from external compression and isolates the heat source of the heating coil 500, further improving the anti-interference capability and long-term operational reliability of the control component 100.

[0047] Preferably, such as Figure 6 and Figure 7As shown, the rear end of the second frame 12 has a first opening slot 121 and / or a second opening slot 122. An opening slot is a through-hole in the frame for pipes or cables to pass through; the rear side of the opening is open to facilitate the insertion of the corresponding pipe. The first opening slot 121 is used to pass through the first pipe 401 and the wire 301 connected to the ejection mechanism 300, which supplies power to the ejection mechanism 300 (e.g., a push-pull electromagnet). The second opening slot 122 is used to pass through the second pipe 402. The first pipe 401 and the second pipe 402 are respectively connected to the volute 400 to achieve coolant circulation. Specifically, the coolant enters the volute 400 and related pipes through one of the pipes, flows through the treatment area to remove heat, and then returns through the other pipe, forming a continuous circulating cooling system.

[0048] This embodiment constrains the routing path of pipes and wires 301 by pre-setting openings in the second frame 12. This effectively avoids the disorderly distribution of internal cables and pipes, providing favorable support and routing space for each pipe, and preventing damage caused by cable and pipe entanglement, compression, or interference with moving parts. The opening design also facilitates the installation of cables and pipes; during assembly, they can be simply snapped into the corresponding slots for positioning without the need for additional fixing devices.

[0049] Furthermore, the external cable 331 is soldered to the end of the coil winding 501 leading from the heating coil 500 to form a soldered end. Specifically, the cable 331 is led out from the electrical connector 33, and the coil winding 501, which supplies power or transmits signals to the heating coil 500, needs to be connected to the signal line (via cable 331) from the control circuit board 20. The end of the cable 331 is soldered to the end of the coil winding 501, and this solder joint is the soldered end. In this embodiment, the soldered end is covered with an adhesive heat shrink tubing 700.

[0050] The adhesive-coated heat shrink tubing 700 is a type of heat shrink tubing with an inner wall coated with hot melt adhesive. After being fitted onto the welding end and heated, the heat shrink tubing shrinks radially, and the hot melt adhesive on its inner wall melts and flows, filling all gaps between the tubing, the welding end, and the wire. Upon cooling, the hot melt adhesive solidifies, forming a tightly wrapped insulating protective layer around the welding end together with the tubing. This protective layer not only provides reliable electrical insulation but also effectively prevents the welding point from being stretched or bent by external forces, eliminating the risk of weld breakage due to stress concentration. Simultaneously, the adhesive-coated heat shrink tubing 700 also acts as a sealant and moisture barrier, further enhancing the long-term reliability of the electrical connection. This embodiment achieves full-enclosure protection of the welding point in a simple, efficient, and low-cost manner by using the adhesive-coated heat shrink tubing 700 over the welding end, significantly enhancing the tensile strength and insulation performance of the cable connection and improving the long-term operational reliability of the product in complex operating environments.

Based on the embodiments of the present invention, those skilled in the art can make other variations or modifications without creative effort, and all such variations or modifications should fall within the scope of protection of the present invention.
