Description

Technical Field

[0003]

[0001] The present invention relates to the field of medical care equipment, and specifically to an intelligent medical bed system for automatically laying disposable pads. Background Art

[0002] In clinical medical care, disposable medical pads are the core protective consumables for medical beds, used to isolate patients' body fluids and secretions, reducing the risk of nosocomial cross-infection. Currently, the automatic pad laying devices supporting medical beds generally adopt a structure with a single set of winding mechanisms and one-way full-bed paving, which can only achieve the full coverage paving of a single-width pad in one direction, and there are core technical defects that cannot be overcome through conventional adjustments: Firstly, the waste of consumables is serious, which goes against the clinical cost reduction requirements. In clinical practice, the contamination of the bed surface mostly concentrates in local small areas such as the headrest, perineum, and buttocks. However, with the existing full-bed paving structure, regardless of the size of the contaminated area, the entire pad needs to be replaced, resulting in a large amount of effective consumables being discarded meaninglessly; especially in scenarios with high-frequency pad replacement such as ICUs and geriatric care homes, this mode significantly increases the consumable usage and the operating costs of medical institutions.

[0003] Secondly, it cannot adapt to different protection requirements and cannot balance the protection effect and economy. The bed surface protection requirements vary significantly for different patients and different treatment stages. Postoperative patients, incontinent patients, and long-term bedridden patients all have corresponding directional protection requirements. However, the existing single-set paving structure can only lay pads of the same specification and protection level across the whole bed, and cannot provide directional enhanced protection for high-risk areas. It is extremely easy to have the risk of cross-infection caused by insufficient local protection or cost out-of-control caused by excessive protection across the whole bed, and the two cannot be balanced. Summary of the Invention

[0004] The technical solution of the present invention is to provide an intelligent medical bed system for automatically laying disposable pads. By orthogonally and hierarchically laying a full-bed covering base pad and a surface pad that can be locally replaced, it balances the basic protection of the whole bed and the local key protection, significantly reduces the waste of consumables, and at the same time can flexibly adjust the protection area, significantly improving the protection accuracy and scenario adaptability, and meeting various differential nursing protection requirements.

[0005] To achieve the above object, the present invention provides the following technical solution: It includes a bed body, two sets of winding devices, pads, and a position adjustment mechanism; The pad running directions of the two sets of winding devices are perpendicular to each other; Each set of winding devices includes a pair of unwinding shafts and winding shafts, and both the unwinding shafts and winding shafts are assembled on the bed body through mounting brackets; The two sets of winding devices are respectively a longitudinal winding device and a transverse winding device; The axes of the unwinding shaft and the winding shaft of the longitudinal winding device are both parallel to the width direction of the bed and are respectively located at the head end and the foot end of the bed in the length direction of the bed, for laying longitudinal mats with the conveyor belt direction parallel to the length direction of the bed.

The two shafts are respectively located on the left and right sides of the width direction of the bed and are used to lay the transverse pad with the direction of the belt running parallel to the width direction of the bed. The transverse pad is located above the longitudinal pad. The position adjustment mechanism is installed between the bed and the mounting bracket of the transverse winding device, and is used to drive the transverse winding device to reciprocate along the length of the bed.

[0006] As a further embodiment of the present invention, the position adjustment mechanism includes a guide rail, a slider, and fasteners; at least one guide rail is fixedly installed on each side of the bed, the slider is slidably assembled in the guide rail, the mounting bracket of the transverse winding device is fixed on the slider, and the fasteners are used to lock the relative position of the slider and the guide rail.

[0007] As a further embodiment of the present invention, the slider is provided with a positioning groove, and the mounting bracket of the transverse winding device is inserted and assembled in the positioning groove. The fastener can penetrate the slider and the mounting bracket to which it is inserted, locking the two into an integrated assembly structure. The guide rail has a through groove extending along its length on its side wall, and the rod of the fastener is slidably fitted into the through groove.

[0008] As a further embodiment of the present invention, mounting brackets are provided at both ends of the unwinding shaft and the winding shaft of the transverse winding device. Each of the guide rails is slidably fitted with two sliders, and the two sliders are respectively fixed to two mounting brackets on the same side of the transverse winding device. The two sliders can slide independently along the guide rail to adjust their distance, adapting to the installation and use of horizontal pads of different widths.

[0009] As a further embodiment of the present invention, the mounting bracket has an opening that tilts upwards to accommodate the end of the unwinding or rewinding shaft. The mounting bracket is fixed with a rotating shaft and a positioning shaft on the side wall corresponding to the slot, and the rotating shaft and the positioning shaft are arranged vertically at intervals along the height direction of the slot. The side wall of the mounting bracket is also provided with a stop bar for closing the slot, and the two ends of the stop bar are respectively provided with a sliding groove and a hook-shaped groove; The slide groove slides and rotates with the rotating shaft, and the groove wall of the hook-shaped groove is composed of a limiting section and an open section connected in sequence; The stop bar can slide along the rotating shaft via a slide groove to switch the corresponding position of the positioning shaft in the hook groove.

[0010] As a further embodiment of the present invention, a lifting member is rotatably connected to the side of the bed body at a position corresponding to the bed surface; The lifting member can contact and cooperate with the surface of the transverse pad, and passively rotate around its rotation axis by the friction generated when the transverse pad moves, so as to increase the vertical distance between the transverse pad and the longitudinal pad.

[0011] As a further aspect of the present invention, a limiting block is fixedly provided at the rotating connection end of the lifting member near the rotating shaft, and the limiting block is used to limit the rotation angle of the lifting member.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. A longitudinally rolled-up device lays a full-coverage longitudinal drape as a basic protective layer, achieving complete isolation between the bed and the patient, preventing bodily fluid leakage and contamination of the bed, and eliminating the need for frequent overall replacement. Simultaneously, a transversely rolled-up device lays an upper transverse drape as a locally replaceable surface protective layer, which can be used to target areas with high-frequency contamination and high protection requirements. Local contamination only requires replacement of the corresponding transverse drape, eliminating the need for a complete bed drape change. This meets the all-time protection needs of long-term bedridden patients and those with urinary and fecal incontinence, while significantly reducing the ineffective waste of protective consumables and substantially lowering the operating costs of medical institutions and home care.

[0015] 2. The horizontal winding device is driven by the position adjustment mechanism to move back and forth along the length of the bed. The position of the horizontal pad can be flexibly adjusted according to the patient's height, position, contaminated area, and key protection area. It can also perfectly adapt to various differentiated scenarios such as preventing leakage of postoperative incisions, high-absorbency protection for incontinent patients, directional laying of cooling pads for febrile patients, and special protection against pressure ulcers for high-risk patients.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-10 The present invention provides a technical solution comprising a bed body 1, two sets of winding devices, a mattress pad, and a position adjustment mechanism 2; In this embodiment, the bed 1 is preferably a medical bed with electric lifting function, which is achieved by a scissor lift driven by a motor. Specifically, a scissor lift is installed at the bottom of the bed 1. The scissor lift is connected to the drive motor. When the motor is working, it drives the scissor lift to extend or retract, thereby driving the bed 1 to rise and fall smoothly, which is convenient for adjusting to a suitable height in conjunction with the padding operation. The two sets of retractable devices have their drapes traveling perpendicular to each other, forming an orthogonal layered drape system. This system can simultaneously meet the dual needs of basic protection for the entire bed surface and key protection for local areas, adapting to the differentiated protection scenarios of different patient groups and breaking through the application limitations of the existing unidirectional full-bed drape structure. Each set of winding devices includes a pair of unwinding shafts 15 and winding shafts 16. The unwinding shafts 15 and winding shafts 16 are mounted on the bed frame 1 via mounting brackets 4. The unwinding shafts 15 and winding shafts 16 of each set of winding devices cooperate to realize the continuous laying and retrieval of the corresponding pads. The paired shaft structure can realize the synchronous laying and retrieval of pads, and is suitable for laying pads of various materials and specifications such as disposable non-woven pads, highly absorbent nursing pads, and reusable cotton protective pads, with strong compatibility. In this embodiment, the unwinding shaft 15 and the take-up shaft 16 adopt an electric roller structure with a built-in motor. Specifically, the unwinding shaft 15 and the take-up shaft 16 are each independently configured as electric rollers or motor-integrated rollers, which integrate a drive motor to directly drive the roller body to rotate, thereby realizing the active unwinding and active take-up of the pads wound on them. With this design of built-in motor or electric roller, there is no need to set up an external motor, reducer and transmission components, making the overall structure of the take-up device more compact, easier to install and maintain, and able to precisely adjust the tension of the pads and the belt speed by controlling the speed and direction of the motor, thereby reliably cooperating with the position adjustment mechanism 2 to realize the automatic laying and replacement of the longitudinal pads 12 and the transverse pads 14.

[0020] The two winding devices are a longitudinal winding device 11 and a transverse winding device 13; The axes of the unwinding shaft 15 and the winding shaft 16 of the longitudinal winding device 11 are parallel to the width direction of the bed body 1 and are respectively located at the head end and the foot end of the bed body 1 in the length direction. They are used to lay longitudinal pads 12 with the direction of the running belt parallel to the length direction of the bed body 1. The longitudinal pads 12 cover the entire bed surface of the bed body 1 as a basic protective layer. The longitudinal pads 12 are made of cotton protective pads that can be repeatedly disinfected and used as a basic protective layer. The longitudinal pads 12 covering the entire bed surface can achieve complete isolation between the bed body 1 and the patient, avoiding leakage and contamination of the bed body 1 by the patient's body fluids and secretions. It is suitable for the basic protection needs of all bedridden patients, especially for the all-time bed surface protection of long-term bedridden patients and patients with urinary and fecal incontinence. It does not require frequent overall replacement, but only requires partial replacement with the upper pad, which greatly reduces the amount of consumables used and the nursing operation time. The axes of the unwinding shaft 15 and the winding shaft 16 of the transverse winding device 13 are parallel to the length direction of the bed 1. The two shafts are respectively located on the left and right sides of the width direction of the bed 1, and are used to lay transverse pads 14 with the direction of the conveyor belt parallel to the width direction of the bed 1. The transverse pads 14 are located above the longitudinal pads 12 and serve as a replaceable surface protective layer. The transverse pads 14 are made of disposable non-woven fabric or highly absorbent nursing pads and serve as a key protective layer. The transversely set surface protective pads can be used for the patient's head, back, buttocks, perineum, and heels. The device provides targeted coverage for areas with high-frequency contamination and high protection requirements, such as the ward. When local contamination occurs, only the corresponding horizontal pad 14 needs to be collected and replaced separately, without replacing the entire vertical pad 12 on the bed surface. It is perfectly adapted to various differentiated scenarios, such as leakage prevention at the incision site of postoperative patients, high-absorbency protection for the perineum of incontinent patients, targeted laying of cooling pads for the headrest of febrile patients, and special laying of pressure ulcer prevention pads for bony prominences of high-risk patients. While improving the accuracy of protection, it significantly reduces the ineffective waste of protective consumables and lowers the operating costs of medical institutions and home care.

[0021] The position adjustment mechanism 2 is installed between the bed body 1 and the mounting bracket 4 of the transverse winding device 13. Its fixed end is fixed to the bed body 1 and its moving end is fixed to the mounting bracket 4. It is used to drive the transverse winding device 13 to move back and forth along the length of the bed body 1 to adjust the laying area of ​​the transverse pad 14 on the longitudinal pad 12. The reciprocating adjustment structure can flexibly adjust the laying position of the transverse pad 14 according to the patient's height, position, contaminated area, and key protection area.

[0022] This system achieves a dual balance between basic protection for the entire bed and targeted protection for specific areas, significantly reducing consumable costs and resource waste. Specifically, a longitudinally rolled-up device 11 lays a longitudinally rolled-up drape 12 covering the entire bed surface as a basic protective layer, achieving complete isolation between the bed 1 and the patient, preventing leakage and contamination of the bed 1, and eliminating the need for frequent overall replacement. Simultaneously, a transversely rolled-up drape 14 is laid on top as a replaceable surface protective layer, allowing for targeted coverage of areas with high-frequency contamination and high protection requirements. For localized contamination, only the corresponding transverse drape 14 needs to be replaced, eliminating the need for a complete bed drape change. This system meets the all-time protection needs of patients who are bedridden for extended periods or incontinent, while significantly reducing the ineffective waste of protective consumables and substantially lowering the operating costs of medical institutions and home care. The accuracy and adaptability of protection are greatly improved, which can fully meet the differentiated protection needs. Specifically, the horizontal winding device 13 is driven by the position adjustment mechanism 2 to move back and forth along the length of the bed 1. The position of the horizontal pad 14 can be flexibly adjusted according to the patient's height, position, contaminated area, and key protection area. At the same time, it can perfectly adapt to various differentiated scenarios such as preventing leakage of postoperative incisions, high-absorbency protection for incontinent patients, directional laying of cooling pads for febrile patients, and special protection against pressure ulcers for high-risk patients.

[0023] As a further embodiment of the present invention, the position adjustment mechanism 2 includes a guide rail 21, a slider 3, and a fastener 32; At least one guide rail 21 is fixedly installed on each of the left and right sides of the bed body 1, and the extension direction of the guide rail 21 is parallel to the length direction of the bed body 1. The slider 3 is slidably assembled in the inner cavity of the guide rail 21, forming a sliding fit with the guide rail 21 along the length of the bed body 1; The mounting brackets 4 on the left and right sides of the transverse winding device 13 are fixedly mounted on the sliders 3 in the guide rails 21 on the same side of the bed body 1. Fastener 32 is assembled between slider 3 and guide rail 21 to lock the relative position of slider 3 and guide rail 21; in this embodiment, fastener 32 is a bolt and nut assembly; The working process of this embodiment is as follows: When it is necessary to adjust the laying area of ​​the horizontal pad 14, loosen the fastener 32 to release the locking limit between the slider 3 and the guide rail 21, so that the slider 3 can be pushed to slide back and forth along the extension direction of the guide rail 21, and simultaneously drive the horizontal winding device 13 to move along the length direction of the bed body 1; after the horizontal winding device 13 moves to the position corresponding to the target protection area, tighten the fastener 32 to lock the relative position of the slider 3 and the guide rail 21. This implementation adopts a purely mechanical sliding adjustment and locking structure, which is simple in overall structure, convenient to operate, and reliable in positioning. It does not require complex electric drive components, has low manufacturing cost and low failure rate, and can be directly adapted to the modification and installation of existing conventional medical beds, making it highly clinically practical. At the same time, the laying position of the transverse drape 14 can be flexibly adjusted according to the patient's position, contaminated area, and key protection areas to cover the target protection area, avoid blind spots, and adapt to the differentiated protection needs of different patients and different stages of diagnosis and treatment. As a further embodiment of the present invention, the slider 3 is provided with a positioning groove 31, and the mounting bracket 4 of the transverse winding device 13 is inserted and assembled in the positioning groove 31 to realize the pre-positioning assembly of the mounting bracket 4 and the slider 3. Fastener 32 can penetrate the slider 3 and the mounting bracket 4 that is inserted and mated with it, locking the mounting bracket 4 and the slider 3 into an integrated assembly structure; The guide rail 21 has a through groove 22 extending along its length on its side wall. The rod of the fastener 32 is slidably fitted into the through groove 22. The through groove 22 provides full clearance space for the sliding of the fastener 32, avoiding structural interference during the adjustment process. When the fastener 32 is tightened, the slider 3 is locked and fixed relative to the guide rail 21, ensuring that the position of the transverse winding device 13 is stable during the towel laying operation and will not shift. When the fastener 32 is loosened, the locking state between the slider 3 and the guide rail 21 is released, and the slider 3 can drive the mounting bracket 4 to slide synchronously along the length direction of the guide rail 21, so as to realize the flexible adjustment of the laying position of the transverse winding device 13. Specifically, the insertion assembly structure of the positioning slot 31 enables quick alignment and installation of the mounting bracket 4 and the slider 3, as well as replacement of the winding device, simplifying the assembly and disassembly process for on-site assembly, subsequent maintenance, and replacement of the pad. Combined with the through-locking structure of the fastener 32, it ensures the connection strength between the mounting bracket 4 and the slider 3, preventing bracket wobbling or displacement during pad placement, and also achieves an integrated design of assembly, adjustment, and locking functions. The sliding fit structure of the through slot 22 and the fastener 32 not only guides the slider 3's sliding stroke throughout its entire range but also allows for direct switching between sliding adjustment and position locking via the tightness of the fastener 32, eliminating the need for additional locking components. The overall structure is simple, easy to operate, and reliable in positioning, fully adapting to the high-frequency adjustment needs of clinical nursing scenarios.

[0024] As a further embodiment of the present invention, mounting brackets 4 are provided at both ends of the unwinding shaft 15 and the winding shaft 16 of the transverse winding device 13. Each guide rail 21 has two sliders 3 slidably assembled inside it. The two sliders 3 are respectively fixed to the two mounting brackets 4 on the same side of the transverse winding device 13. The two sliders 3 can slide independently along the guide rail 21 without interfering with each other during the sliding process. By adjusting the distance between the two sliders 3, it can flexibly adapt to the installation and use of horizontal pads 14 with different widths without replacing the guide rail 21, sliders 3 and other components, thereby improving the system's compatibility and versatility, adapting to the differentiated needs of different patients and different protection scenarios in clinical practice for the width of the horizontal pads 14, and reducing equipment maintenance and replacement costs.

[0025] As a further embodiment of the present invention, the mounting bracket 4 has an opening that is inclined upward for accommodating the shaft end of the unwinding shaft 15 or the take-up shaft 16; the inner diameter of the slot 41 is adapted to the outer diameter of the shaft end of the unwinding shaft 15 or the take-up shaft 16, so as to provide stable radial bearing for the shaft end. The mounting bracket 4 is fixed with a rotating shaft 42 and a positioning shaft 43 on the side wall corresponding to the slot 41. The rotating shaft 42 and the positioning shaft 43 are arranged vertically at intervals along the height direction of the slot 41. Their axes are parallel to each other and both are perpendicular to the side wall of the mounting bracket 4, ensuring precise and interference-free operation. The side wall of the mounting bracket 4 is also provided with a stop bar 5 for closing the opening of the slot 41. The two ends of the stop bar 5 are respectively provided with a sliding groove 51 and a hook groove 52. The length of the stop bar 5 covers the opening width of the slot 41, and can close the upper opening of the slot 41. The slide groove 51 slides and rotates with the rotating shaft 42. The groove wall of the hook groove 52 is composed of a limiting section 53 and an open section 54 connected in sequence. The limiting section 53 is an arc-shaped groove that matches the outer diameter of the positioning shaft 43, which can achieve stable locking. The open section 54 is an open channel for the positioning shaft 43 to enter and exit the hook groove 52. The stop lever 5 can slide back and forth along the rotating shaft 42 via the slide groove 51 to switch the corresponding position of the positioning shaft 43 in the hook groove 52, thereby realizing the rapid switching between the locked state and the openable state. See Figure 7 When the positioning shaft 43 is located in the open section 54 of the hook groove 52, the stop rod 5 can rotate around the rotating shaft 42 to control the opening and closing of the groove 41. At this time, the stop rod 5 can be flipped upward to fully open the upper opening of the groove 41, so as to realize the quick disassembly and replacement of the unwinding shaft 15 and the rewinding shaft 16. After replacing the unwinding spool 15 and the rewinding spool 16, the reversal is performed (i.e., Figure 7 (In the direction of the black arrow) Rotate the stop bar 5. When the positioning shaft 43 re-engages into the open section 54 of the hook groove 52, move the stop bar 5 along the length of the slide groove 51 so that the positioning shaft 43 engages into the limiting section 53 of the hook groove 52. At this time, the rotation angle of the stop bar 5 is locked, thereby closing the opening of the groove 41 and forming a radial limit on the end of the roll shaft in the groove 41, preventing the roll from coming out of the groove 41 during the winding and unwinding operation, and ensuring the stable operation of the towel laying operation.

[0026] As a further embodiment of the present invention, a lifting member 6 is rotatably connected to the side of the bed body 1 corresponding to the position of the bed surface. The rotation axis of the lifting member 6 is fixed to the side of the bed body 1 corresponding to the side of the transverse mattress 14. The axis of the rotation axis is parallel to the length direction of the bed body 1. The lifting member 6 is located entirely below the transverse mattress 14. The lifting component 6 can contact and cooperate with the surface of the transverse pad 14. It passively rotates around its rotation axis by relying on the friction generated when the transverse pad 14 moves. The contact working surface of the lifting component 6 is stably attached to the lower surface of the transverse pad 14, ensuring that the lifting component 6 can be driven to rotate synchronously when the transverse pad 14 is moved. When the transverse pad 14 moves with the transverse winding device 13, the transverse pad 14 becomes taut, increasing the positive pressure between it and the lifting member 6. This causes the lifting member 6 to rotate under frictional force, and its free end rises upward, lifting the transverse pad 14 to increase the vertical distance between the transverse pad 14 and the longitudinal pad 12. During the rotation of the lifting member 6, the transverse pad 14 and the longitudinal pad 12 are physically separated throughout the entire movement of the transverse pad 14, completely avoiding frictional interference between them. After the transverse pad 14 above the bed 1 is completely replaced, the winding shaft 16 stops rotating, and the unwinding shaft 15 releases one end of the transverse pad 14 and stops, leaving the transverse pad 14 in a relaxed state, reducing the positive pressure between it and the lifting member 6. The lifting member 6 naturally falls back to its original position under its own weight, without interfering with the patient's lying position or affecting the normal use of the bed 1.

[0027] As a further embodiment of the present invention, a limiting block 61 is fixedly provided at the rotating connection end of the lifting member 6 near the rotating shaft. The limiting block 61 and the rotating connection end of the lifting member 6 are rigidly connected to form an integral synchronous rotating structure. Its stop end is set towards the fixed stop position on the bed body 1, and it rotates synchronously with the lifting member 6 without relative displacement. The limiting block 61 is used to limit the rotation angle of the lifting member 6. By abutting and cooperating with the fixed stop structure on the bed 1, it limits the rotation stroke range of the lifting member 6 and constrains the maximum rotation angle of the lifting member 6 when it is lifted upward. This prevents the lifting member 6 from rotating excessively, which would cause the transverse pad 14 to re-contact with the longitudinal pad 12 and affect the winding of the transverse pad 14.

[0028] As a further embodiment of the present invention, baffles 7 are provided along the length of the left and right sides of the bed body 1. The baffles 7 are located outside the path of the transverse mattress 14. The baffles 7, which are provided along the length, cover the entire range of movement of the transverse winding device 13 along the length of the bed body 1. This can provide a stable mounting carrier for the supporting components and does not interfere with the normal movement of the transverse winding device 13 and the mattress winding and unwinding operations. The inner wall of the baffle 7 is equipped with a sterilization device. The active end of the sterilization device faces the surface of the transverse drape 14 and is used to sterilize and disinfect the transverse drape 14. The sterilization device can use compliant clinical sterilization components such as medical-grade ultraviolet sterilization modules and plasma sterilization modules. Its active end is directly facing the exposed surface of the transverse drape 14 throughout the process. It can continuously and fully cover the surface of the drape during the movement of the transverse drape 14, effectively killing pathogens on the surface of the drape, further reducing the risk of cross-infection in the hospital, and fully complying with the standard requirements for clinical infection control management.

[0029] As a further embodiment of the present invention, the baffle 7 is provided with opening slots 71 at both ends along its length direction. The opening slots 71 are U-shaped slots extending along the height direction of the baffle 7. The openings of the opening slots 71 are set facing the lower part of the bed body 1. The inner diameter of the slot is matched with the outer diameter of the mounting shaft 72 to ensure that the fit is stable and there is no loosening or shaking after the slot is installed. A mounting shaft 72 is provided on the side of the bed body 1. The mounting shaft 72 is vertically fixed to the side plate of the bed body 1 and rigidly connected to the bed body 1, providing stable mounting support for the baffle 7, and there is no relative displacement during use. The baffle 7 is snapped onto the mounting shaft 72 via the opening slot 71, achieving a detachable assembly connection with the bed 1. This snap-fit ​​detachable structure allows for quick assembly and disassembly of the baffle 7 without the need for additional tools. When cleaning, maintenance, or replacement of the baffle 7 and sterilization device is required, simply lift the baffle 7 upwards to disengage the opening slot 71 from the mounting shaft 72 to complete disassembly. During installation, simply align the opening slot 71 with the mounting shaft 72 and lower it into place to complete assembly. This significantly simplifies the equipment maintenance process and reduces the operational difficulty of clinical operation and maintenance. At the same time, the U-shaped groove structure design allows for stable engagement by the baffle 7's own weight during use, preventing it from detaching on its own and ensuring the stability and reliability of the equipment operation.
