Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a controller and nebulizer assembly. Background Technology

[0002] In the ICU, critically ill patients, even those without spontaneous breathing ability, require nebulizers in conjunction with ventilators, oxygen concentrators, and humidifiers for nebulization therapy. 50%–70% of ICU patients require mechanical ventilation, and during mechanical ventilation, nebulization therapy is used in 99.99% of cases. Nebulizers can atomize various inhaled medications, such as bronchodilators, corticosteroids, antibiotics, agonists, and antihistamines. The medications are aerosolized by the nebulizer and delivered directly to the lungs through the patient's mouth and nose via the ventilator tubing, making it a more efficient method for treating respiratory diseases.

[0003] In general wards or nebulization rooms, for patients with spontaneous breathing ability, during the perioperative period or acute exacerbation of respiratory diseases, nebulizers are used in conjunction with wall oxygen to quickly and accurately deliver drug aerosols to patients.

[0004] Existing nebulizers used in hospital settings are all connected via controller cables. However, these cables are quite long. When used in conjunction with ventilator tubing in ICU or with wall oxygen in general wards, the controller cables inevitably cause inconvenience to treatment operations and may even affect the patient's treatment time in emergencies. Utility Model Content

[0005] The purpose of this invention is to provide a controller and nebulizer assembly to solve the problem in the prior art where the nebulizer requires a connection cable via a controller, causing inconvenience during treatment. The specific technical solution is as follows:

[0006] In one aspect, this utility model provides a controller that can be engaged with a protruding connecting part on an atomizer. The controller includes a support part and a plug part. An electrical plug is provided on the plug part, which can be inserted into the pin of the atomizer. The bottom of the support part is recessed downward to form a support surface that adapts to the outer contour of the connecting part of the atomizer. A retractable stop is provided on the support surface. When the stop extends, it can abut against the side of the connecting part of the atomizer away from the plug part to form a clamping constraint on the connecting part of the atomizer. When the stop retracts, the clamping constraint is released.

[0007] Furthermore, the controller also includes a stop base and a press button assembly. The stop base is located inside the controller, and a stop block is connected to the side of the stop base near the bearing surface. A guide ramp is also provided on the side of the stop base. The press button assembly includes a button located outside the controller and a pressure column located inside the controller. The pressure column abuts against the guide ramp. Pressing the press button assembly can cause the pressure column to generate a thrust on the stop base, causing the stop block to retract from the bearing surface.

[0008] Furthermore, the stop block is connected to the middle position of the stop block base, and the stop block base forms a guide slope on each side of the stop block; there are two pressure columns, and the two pressure columns abut against the guide slopes on both sides of the stop block, so that the stop block has mutually cooperating guide slopes and pressure columns on both sides.

[0009] Furthermore, a top cover is provided above the block base, and a plug groove is provided at the bottom of the top cover. The controller has a plug rib that matches the plug groove. The plug groove and the plug rib are connected to each other. The top cover forms a receiving space for accommodating the block base. A through hole is provided at the middle of the top of the top cover for the block to pass through, so as to limit the movement path of the block through the through hole.

[0010] Furthermore, the side of the stop block away from the insertion part is a self-guiding slope that slopes from the bottom to the top. When the self-guiding slope is squeezed, the stop block can retract.

[0011] Furthermore, a spring fixing post is provided at the bottom of the inner side of the controller, a first step hole is provided at the bottom of the stop block base, a first spring is provided between the stop block base and the bottom of the controller, the first spring is inserted into the spring fixing post, one end of the first spring is connected to the first step hole at the bottom of the stop block base, and the other end of the first spring abuts against the bottom of the controller, so as to apply an elastic force away from the bottom of the controller to the stop block base.

[0012] Furthermore, a second spring is provided between the two pressure columns. One end of the second spring abuts against the side of the stop block, and the other end of the second spring abuts against the inner side of the button, so as to apply a spring force away from the stop block to the button.

[0013] Furthermore, the bearing part and the plug-in part are arranged adjacent to each other in the longitudinal direction, and the bearing surface of the bearing part is an arc groove that is recessed in the transverse direction; the stop includes two sets, and the two sets of stop are symmetrically distributed on both sides of the bearing surface in the transverse direction, and the button corresponding to each stop is respectively arranged on different sides of the controller in the transverse direction.

[0014] Furthermore, the plug-in portion includes a receiving portion, which includes a first recessed surface that is recessed downward and a first protruding surface that is protruding upward. The first recessed surface and the first protruding surface are arranged opposite each other to form a hollow plug-in receiving groove. One end of the plug-in receiving groove is adjacent to the support portion, and the other end extends into the controller in a direction away from the support portion. The electrical plug is disposed in the plug-in receiving groove so that the plug end of the electrical plug is disposed close to the support portion, and the other end of the electrical plug extends into the controller.

[0015] Furthermore, the first concave surface and the first convex surface are staggered so that the end of the first concave surface near the support portion extends beyond the end of the first convex surface to form a clearance space, and the end of the first convex surface away from the support portion extends beyond the end of the first concave surface to form a fixing space for the electrical plug.

[0016] Furthermore, the electrical plug is provided with a fixing rib extending in the circumferential direction of the electrical plug at one end inside the controller. The controller is provided with a pressure plate, and the pressure plate is provided with a fixing groove that matches the fixing rib, so that the fixing rib can be accommodated and locked in the fixing groove.

[0017] Furthermore, the electrical plug has a stepped structure along the axial direction, and the outer diameter of each stepped structure gradually increases from the outside of the controller to the inside of the controller, so that at the end outside the plug-in groove, there is a space for plugging in between the electrical plug and the plug-in groove, and at the end inside the plug-in groove, the outer contours of the electrical plug and the plug-in groove match each other to fix the electrical plug.

[0018] Another aspect of this utility model also provides an atomizer assembly, including an atomizer and the controller described in the above-mentioned items. The atomizer includes a medicine cup, a medicine cup base and a mist reservoir connected in sequence. The medicine cup base is a cylindrical connecting part protruding from the atomizer body. The medicine cup base is engaged with the controller. The medicine cup is disposed adjacent to the controller and the mist reservoir extends away from the controller.

[0019] Furthermore, a pin is provided on the end face of the medicine cup base, which can be plugged into the electrical plug of the controller. The end face of the medicine cup base away from the pin abuts against the stop block, so that the stop block clamps and constrains the medicine cup base.

[0020] The controller of this utility model has the following advantages:

[0021] 1. By using a pin-plug direct connection, the traditional cable connection between the atomizer and the controller is eliminated, improving the ease of operation. At the same time, it can achieve dual positioning of electrical connection and mechanical locking, so that the atomizer and the controller form a stable connection.

[0022] 2. The dual pressure columns form a symmetrical load distribution, which makes the stress of the block retraction movement evenly distributed; the double-sided guide slope layout compresses the axial length of the block base, reducing the thickness of the controller, which is particularly suitable for the spatial constraints in hospital equipment-dense scenarios.

[0023] 3. The side of the stop block away from the insertion part is a self-guiding slope. During the insertion of the atomizer, the connection part contacts the self-guiding slope to generate a combined force, which drives the stop block to automatically retract to the bearing surface to achieve non-intervention avoidance.

[0024] 4. The push button assembly adopts a dual-group symmetrical layout, which is placed on the left and right side walls of the support. This design supports one-handed operation. By pressing the push button assembly, the stop block is controlled to retract synchronously, and the other hand can hold the nebulizer to perform insertion and removal. Compared with the traditional two-hand unlocking operation, the force required is reduced. The ergonomic optimization significantly improves the operating efficiency of medical staff, and is especially suitable for rapid equipment switching in emergency scenarios.

[0036] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0037] Figures 1-2 The diagram shows an overall structural schematic of an atomizer assembly provided in an embodiment of the present invention. The atomizer assembly provided in this embodiment includes an atomizer 2 and a controller 1. The atomizer 2 can be snapped onto the controller 1, making it a single unit that is easy to carry or operate. At the same time, since the atomizer 2 can be snapped onto the controller 1, the connecting wire of the controller 1 is omitted, avoiding the inconvenience caused by the connecting wire of the atomizer 2 to the use of the atomizer 2.

[0038] It should be noted that the medical nebulizer 2 is primarily used in hospital environments, where patients are typically bedridden and lack the means to operate it manually. Therefore, the medical nebulizer 2 is usually fitted with a breathing mask, and when necessary, it will be embedded in the ventilator circuit to provide medication aerosol to the patient. To accommodate this, the design of the medical nebulizer 2 tends to employ a linear connection structure, meaning the reservoir 23 and the medication cup 21 are arranged in a straight line. The core advantages of this design are: the linear connection places the medication cup 21 at the far end of the reservoir 23's mist outlet, thus preventing it from accumulating near the patient's face; it effectively prevents various accessories (such as tubing and cups) from converging at the patient's mouth and nose, reducing equipment redundancy in the facial area and minimizing pressure and interference; the linear structure makes the equipment layout simpler and more balanced, significantly improving patient comfort when wearing a breathing mask.

[0039] Furthermore, the nebulizer 2 provided in this embodiment is based on the existing medical nebulizer 2 structural design and includes three core components: a liquid medicine cup 21, a liquid medicine cup base 22, and a mist storage tank 23. Its structural features are as follows: The liquid medicine cup 21 is designed with an incline, and its bottom is connected to the liquid medicine cup base 22 at a specific angle to ensure complete atomization of the liquid medicine inside, reducing drug residue. An atomizing plate is embedded inside the liquid medicine cup base 22 to convert the liquid medicine into an aerosol; a pin is provided on the outer side of the liquid medicine cup base 22, which connects to the electrical plug 13 of the controller 1. The pin, after being electrically connected to the electrical plug 13, can supply power to the atomizing plate. One end of the mist storage tank 23 is connected to the liquid medicine cup base 22, and the other end extends away from the liquid medicine cup base 22, with a mist outlet at the end that can be connected to a breathing mask or mouthpiece. The liquid cup base 22 is designed as a protruding connection part of the atomizer 2. When the liquid cup base 22 is engaged with the controller 1, its pins precisely align with the electrical plug 13 of the controller 1 to achieve power supply and control of the atomizing plate.

[0040] Furthermore, Figures 3-11 The present invention illustrates a controller 1 provided in an embodiment of the present invention. For ease of description, the extension directions of the two adjacent sides of the controller 1 are defined as the longitudinal direction and the transverse direction, respectively. Specifically, the length direction of the controller 1 can be defined as the longitudinal direction, and the width direction of the controller 1 can be defined as the transverse direction.

[0041] In this embodiment of the utility model, the controller 1 has two functional modules distributed longitudinally: a plug-in part 12 and a support part 11. An electrical plug 13 is provided on the plug-in part 12 for connecting with the pin of the atomizer liquid cup base 22 to achieve circuit conduction. The bottom of the support part 11 is recessed downward to form a support surface that adapts to the outer contour of the atomizer 2 connection part (i.e., the liquid cup base 22), providing physical support and positioning for the connection part.

[0042] Furthermore, a retractable stop 31 is provided on the bearing surface. After the stop 31 extends, it abuts against the side of the liquid cup base 22 of the atomizer 2 away from the insertion part, so as to form a clamping constraint on the liquid cup base 22 of the atomizer 2. After the stop 31 retracts, the clamping constraint is released, so that the atomizer 2 can be separated from the controller 1 under the action of external force.

[0043] Specifically, a stop assembly is provided inside the bearing part 11. The stop assembly includes a stop 31 that can perform telescopic movement on the bearing surface. After the stop 31 extends, it abuts against the side of the medicine cup base 22 away from the plug-in part 12. At this time, since the insert pin is inserted into the electrical plug 13 of the plug-in part 12, the stop 31 can effectively prevent the insert pin from coming loose from the electrical plug 13, thereby forming a clamping constraint on the medicine cup base 22.

[0044] Furthermore, in a specific embodiment of this utility model, the insert is set on the end face of the liquid cup base 22 away from the mist storage tank 23. The insert is connected to the electrical plug 13 of the controller 1. The end face of the liquid cup base 22 away from the insert abuts against the stop block 31 to achieve longitudinal rigid fixation of the liquid cup base 22. After the stop block 31 retracts, the longitudinal clamping constraint is released. At this time, an external force is applied to the atomizer 2 in the longitudinal direction away from the electrical plug 13, so that the insert of the atomizer 2 is disengaged from the electrical plug 13, thereby realizing the disassembly of the atomizer 2.

[0045] The controller 1 provided in this embodiment of the present invention has a smooth connection process and can complete the mechanical and electrical integration. First, it can achieve the advancement and positioning, with the atomizer 2 being moved horizontally along the bearing surface towards the insertion part 12 from the end away from the insertion part 12. Second, it can achieve electrical connection, with the pin of the atomizer liquid cup base 22 precisely inserted into the electrical plug 13 of the controller 1 insertion part 12 under the constraint of the bearing surface, thus achieving circuit conduction. Third, it can achieve mechanical locking, with the block 31 rising synchronously after the liquid cup base 22 of the atomizer 2 passes the stop 31, and rigidly abutting against the end face of the liquid cup base 22 away from the insertion part 12. At this time, a constraint is formed in the longitudinal direction of the atomizer 2, which is the cooperation between the pin and the electrical plug 13, and the constraint is formed in the cooperation between the liquid cup base 22 and the stop 31. This bidirectional constraint can effectively fix the atomizer 2, preventing the pin from falling off the electrical plug 13, and completing the boltless locking. The atomizer 2 and the controller 1 form a stable connection.

[0046] The controller 1 provided by this utility model achieves a cable-free design, directly connecting via a pin-electrical plug, completely eliminating the cable connection between the traditional atomizer 2 and the controller 1, thus improving operational convenience. It also achieves plug-and-play compatibility; the controller 1's bearing surface is customized according to the existing atomizer 2's outer contour, requiring no modification to the atomizer 2's structure. The atomizer 2 is compatible with two types of controllers 1: the wireless card controller 1 in this embodiment, compared to traditional wired controllers, significantly expands the application scenarios of the atomizer 2.

[0047] Further, see Figures 4-11 In this embodiment of the invention, the controller 1 housing consists of a front shell 8 and a rear shell 5 fastened together to form a closed inner cavity. The upper end of the front shell 8 is integrally formed with a support part 11 and a plug-in part 12 for engaging with the atomizer 2. The rear shell 5 has a PCB receiving cavity inside, and a mounting notch for the control key 7 is provided on the side wall. A first positioning hole group (including 4 evenly distributed holes) is provided at the bottom. The front shell 8 also has a first positioning post group corresponding to the first positioning hole group. The front shell 8 and the rear shell 5 can be fixed together by self-tapping screws. In this embodiment of the invention, the control key 7 can be made of elastic silicone / TPU material, which deforms elastically when pressed, thereby triggering the micro switch on the PCB board to generate a control signal. The mounting notch of the controller 1 and the control key 7 is interference-fitted to prevent dust and liquid intrusion.

[0048] Furthermore, in a preferred embodiment of this utility model, the outer contour of the liquid cup base 22 is cylindrical, and the bearing surface of the bearing part 11 is a concave arc groove in the transverse direction, that is, the bearing surface is an arc-shaped structure in the transverse direction. The stop block 31 includes two sets, and the two sets of stop blocks 31 are symmetrically distributed on both sides of the bearing surface in the transverse direction, so that the stop block 31 is fixed to two points at the end of the liquid cup base 22, thereby improving the stability of the atomizer 2. The button 321 corresponding to each stop block 31 is set on the side of the controller 1 in the transverse direction.

[0049] Understandably, in this embodiment of the present invention, the outer contour of the medicine cup base 22 can be square or other shapes. In this case, the stop block assembly can also be set as a set of stop blocks 31 extending along the length of the outer contour, so that the stop blocks 31 can be effectively fixed.

[0050] Furthermore, in this embodiment of the present invention, the stop assembly further includes a stop base 33 and a press button assembly 32. The stop base 33 is disposed inside the controller 1, and the stop block 31 is connected to the side of the stop base 33 near the bearing surface. The stop base 33 is provided with a guide slope 331, which extends inclinedly from a position away from the bearing surface to a position near the bearing surface. The press button assembly 32 includes a button 321 disposed outside the controller 1 and a pressure post 322 disposed inside the controller 1. The end face of the pressure post 322 maintains constant contact with the guide slope 331. When the user presses the button 321 in the lateral direction, the pressure post 322 slides along the guide slope 331, generating a vertical component force through the mechanical conversion of the slope, driving the stop block 31 to retract vertically back to the bearing surface, thereby releasing the longitudinal constraint.

[0051] Furthermore, the push button assembly 32 adopts a dual-group symmetrical layout, placed on the left and right side walls of the support part 11 in the lateral direction. This design supports one-handed operation. By pressing the push button assembly 32, the stop block 31 is controlled to retract synchronously, and the other hand can hold the nebulizer 2 to perform insertion and removal. Compared with the traditional two-hand unlocking operation, the force required is reduced. The ergonomic optimization significantly improves the operating efficiency of medical staff, and is especially suitable for rapid equipment switching in emergency scenarios.

[0052] Further, see Figure 6 , Figure 7 and Figure 9In this embodiment of the invention, the stop block 31 is connected to the middle position of the stop block base 33. The stop block base 33 forms a guide slope 331 on both sides of the stop block 31. Two pressure posts 322 are included, each abutting against the guide slopes on both sides of the stop block, so that both sides of the stop block 31 have mutually cooperating guide slopes 331 and pressure posts 322. The stop block assembly in this embodiment adopts a double-sided force transmission optimization design: the stop block 31 is rigidly connected to the middle of the stop block base 33, and guide slopes 331 are symmetrically formed on both sides of the stop block 31. The correspondingly configured double pressure posts 322 are placed on both sides of the button 321, respectively in constant contact with the double-sided guide slopes 331. The dual pressure columns 322 form a symmetrical load distribution, which makes the stress of the block 31 retracting evenly distributed. Compared with the traditional block and block base being arranged on the same straight line, and the guide slope being a sloped groove located between the block and the block base, the double-sided guide slope 331 layout of this utility model sets the guide slope 331 on both sides of the block 31, which compresses the axial length of the block base 33 and the block 31, thereby reducing the thickness of the controller 1. It is particularly suitable for the spatial constraints in hospital equipment-dense scenarios.

[0053] Further, see Figure 7 , Figure 8 and Figure 10 In this embodiment of the invention, the stop assembly further includes a top cover 35, which is positioned above the stop base 33. The bottom of the top cover 35 has a insertion groove 351, and a corresponding insertion rib 51 matching the insertion groove 351 is provided on the inner side of the rear shell 5. The insertion groove 351 and the insertion rib 51 are interconnected to connect the top cover 35 to the controller 1. The top cover 35 forms an accommodating space to accommodate the stop base 33. A through hole 352 is provided at the center of the top of the top cover 35, through which the stop 31 extends. This invention uses the top cover 35 to confine the stop 31 to a specific position and simultaneously defines the movement path of the stop 31, ensuring a stable connection of the entire stop assembly, controllable movement path, and relatively fixed position, facilitating stable engagement with the atomizer 2 connection.

[0054] Further, see Figure 4 , Figure 6 and Figure 9In this embodiment of the invention, the side of the stop block 31 away from the insertion part 12 is a self-guiding inclined surface 311 that slopes from the bottom to the top. When the self-guiding inclined surface 311 is squeezed, it generates a vertically downward component force, which can retract the stop block 31. When the nebulizer 2 is inserted, the liquid cup base 22 of the nebulizer 2 squeezes the self-guiding inclined surface 311 to generate a vertical component force, causing the stop block 31 to retract. In this embodiment, the stop block 31 adopts a bidirectional differentiated surface design: the side of the stop block 31 away from the insertion part 12 is the self-guiding inclined surface 311, and the side closer to the insertion part 12 is the vertical locking plane 312. During the insertion of the nebulizer 2, the medication cup base 22 contacts the self-guiding inclined surface 311, generating a combined force that drives the stop block 31 to automatically retract to its bearing surface, achieving non-interventional avoidance. After the nebulizer 2 is in place, the stop block 31 returns to its original position and rises, causing its vertical locking plane 312 to form a rigid abutment with the end face of the medication cup base 22 away from the insert needle, continuously applying a clamping force towards the electrical plug 13, effectively preventing the insert needle from coming loose from the electrical plug. This structure simultaneously achieves the dual functions of self-guiding insertion and self-locking positioning: the self-guiding inclined surface 311 significantly reduces the intensity of insertion and removal operations, while the vertical locking plane ensures connection reliability through surface contact constraints; the stop block 31's integrated dual-function design significantly optimizes space occupancy while maintaining high stability, meeting the dual requirements of medical devices for ease of operation and compact structure.

[0055] Furthermore, in this embodiment of the present invention, the stop block 31 is elastically connected to the controller 1. A cylindrical spring fixing post 34 is provided at the bottom of the rear shell 5 of the controller 1, and a stepped first step hole 332 is opened at the corresponding position of the stop block base 33. The two ends of the first spring 37 abut against the inner wall of the first step hole 332 and the bottom surface of the controller 1, respectively, and are sleeved on the outer periphery of the spring fixing post 34 to form an axial guide, thereby applying a spring force away from the base of the controller 1 to the stop block base 33. Under normal conditions, the first spring 37 is in a pre-compressed state, and its elastic force drives the stop block base 33 to move towards the bearing surface, causing the stop block 31 to stably extend out of the bearing surface and remain in a ready-to-engage state with the connection part of the atomizer 2. When an external force is applied to the stop block 31, the stop block base 33 overcomes the spring force and moves axially along the spring fixing post 34, causing the stop block 31 to precisely retract below the bearing surface. This elastic reset mechanism ensures that the stop block 31 automatically returns to its position in the non-locked state, and at the same time, eliminates radial wobble through the post-hole cooperation, ensuring the straightness and repeatability of the movement trajectory.

[0056] Furthermore, in this embodiment of the present invention, a second spring 36 is also provided between the two pressure-applying posts 322 of the button assembly. One end of the second spring 36 abuts against the side of the stop block 31, and the other end of the second spring 36 abuts against the inner side of the button 321, so as to apply a spring force away from the stop block 31 to the button 321. Specifically, a second stepped hole 323 is provided on the inner side of the button 321, and the second spring 26 is connected to the second stepped hole 323. In this embodiment of the present invention, the symmetrical layout of the double-sided pressure-applying posts 322 naturally forms a central clearance space, so that the second spring 36 and the pressure-applying posts 322 achieve zero interference nesting; the second spring 36 is normally pre-compressed to continuously provide the button 321 with a reset spring force away from the stop block 31, which, together with the first spring 37 of the stop block base 33, constitutes a dynamic balance system—in the non-operating state, the stop block 31 stably extends out of the bearing surface, and in the pressing state, the external force overcomes the combined force of the two springs to drive the stop block 31 to retract. The dual springs eliminate lateral vibration through radial limiting structures, and, in conjunction with the axial positioning reference of the stepped hole, ensure the linearity of the movement trajectory and repeatability of the stop 31. This architecture simultaneously achieves improved operational stability, reduced false triggering rate, and enhanced lifespan within an extremely thin space, meeting the reliability requirements of medical devices for precision mechanics.

[0057] Furthermore, such as Figure 3 , Figure 11 As shown in the embodiment of this utility model, the plug-in portion 12 includes a receiving portion, which includes a downwardly recessed first concave surface 41 and an upwardly protruding first convex surface 42. The first concave surface 41 and the first convex surface 42 form a hollow plug-in receiving groove 82 extending longitudinally. One end of the plug-in receiving groove 82 is disposed near the supporting portion 11, and the other end extends away from the supporting portion 11 into the interior of the controller 1. The electrical plug 13 is disposed in the plug-in receiving groove 82, such that the plug-in end of the electrical plug 13 is disposed near the supporting portion 11, and the other end of the electrical plug 13 extends into the interior of the controller 1. This utility model fixes the electrical plug 13 through the receiving portion, providing a channel for the electrical plug 13 to connect the outside and the inside.

[0058] Furthermore, in this embodiment of the invention, the first concave surface 41 and the first convex surface 42 are staggered along the longitudinal direction, such that the end of the first concave surface 41 near the support portion 11 extends beyond the end of the first convex surface 42, forming a clearance space for the liquid cup 21, and the end of the first convex surface 42 away from the support portion 11 extends beyond the end of the first concave surface 41, forming a fixing space for the electrical plug 13. This invention cleverly utilizes the inclined arrangement of the liquid cup 21 and the liquid cup base 22 to keep the liquid cup base 22 perpendicularly connected to the electrical plug 13, while also forming a clearance space for the liquid cup 21 near the support portion 11. This allows for the connection between the atomizer 2 and the controller 1 without requiring any modifications to the shape of the atomizer 2.

[0059] Further, see Figure 3 and Figure 11 In this embodiment of the invention, the electrical plug 13 is provided with a stepped structure 132 along the axial direction. The outer diameter of each stepped structure 132 gradually increases from the outside of the controller 1 to the inside of the controller 1, so that at the end outside the insertion slot 82, an insertion space is formed between the electrical plug 13 and the insertion slot 82. At the end inside the insertion slot 82, the outer contour of the electrical plug 13 matches the outer contour of the insertion slot 82 to fix the electrical plug 13. In this embodiment of the invention, the outer shell of the atomizer 2 pin is connected to the insertion space, and the pin is connected to the socket inside the electrical plug 13, realizing a tight connection between the pin, the electrical plug 13, and the insertion slot 82, further fixing the atomizer 2 and improving the connection stability between the atomizer 2 and the controller 1. At the same time, the outer contour of the electrical plug 13 at the end inside the insertion slot 82 matches the outer contour of the insertion slot 82, which can stably fix the electrical plug 13.

[0060] Further, see Figure 11 The electrical plug 13 has a fixing rib 131 extending circumferentially along one end inside the controller 1. A pressure plate 43 is provided inside the controller 1, and a fixing groove 431 matching the fixing rib 131 is provided on the pressure plate 43, so that the fixing rib 131 is accommodated and locked in the fixing groove 431. Specifically, in this embodiment of the invention, the end of the first protruding surface 42 away from the bearing portion 11 extends beyond the first recessed surface 41 to form a fixing space for the electrical plug 13. The end of the electrical plug 13 inside the controller 1 is fixed in this fixing space by the pressure plate 43. The electrical plug 13 has a fixing rib 131, and the pressure plate 43 has a fixing groove 431. The fixing rib 131 is accommodated in the fixing groove 431, thus fixing the electrical plug 13.

[0061] Furthermore, the front shell 8 is further provided with a plurality of second positioning posts 83, and the pressure plate 43 is provided with corresponding second positioning holes 432. The pressure plate 43 is fixedly installed on the front shell 8 by self-tapping screws. Preferably, the pressure plate 43 is a right-angled structure as shown in the figure, and three second positioning posts 83 and three second positioning holes 432 are respectively located at both ends and corners to improve installation reliability. At the same time, this embodiment of the present invention also provides a light guide post 81 connecting the inner and outer sides of the controller 1. The pressure plate 43 fixes the light guide post 81 in a preset space in the front shell 8. The light guide post 81 can provide an indication of the working status of the atomizer 2, making it easy to identify the working status of the atomizer 2 according to the indication.

[0062] This invention achieves multiple fixation of the electrical plug 13 through the stepped structure 132 of the electrical plug 13, the positioning rib at the end of the electrical plug 13, and the fixing groove 431 of the pressure plate 43, ensuring the reliability of equipment operation. At the same time, the insertion space formed at the front end of the insertion slot 82 further strengthens the connection of the atomizer 2.

[0063] This utility model embodiment provides a controller 1 with the following advantages:

[0064] 1. By using a pin-plug direct connection, the traditional cable connection between the atomizer and the controller is eliminated, improving the ease of operation. At the same time, it can achieve dual positioning of electrical connection and mechanical locking, so that the atomizer and the controller form a stable connection.

[0065] 2. The double pressure columns 322 form a symmetrical load distribution, so that the stress of the retraction movement of the stop block 31 is evenly distributed; the double-sided inclined surface layout compresses the axial length of the stop block base 33, reducing the thickness of the controller 1, which is particularly suitable for the spatial constraints in hospital equipment-dense scenarios.

[0066] 3. The side of the stop block 31 furthest from the plug part 12 is a self-guiding slope 311, and the side closer to the plug part 12 is a vertical locking plane. During the insertion of the atomizer 2, the connecting part contacts the self-guiding slope 311 to generate a combined force, which drives the stop block 31 to automatically retract to the bearing surface to achieve non-intervention avoidance; after the atomizer 2 is in place, the stop block 31 resets and rises so that its vertical locking plane forms a rigid abutment with the back of the connecting part, continuously applying a pressing force pointing towards the electrical plug 13, effectively preventing the insert pin from loosening.

[0067] 4. The push button assembly 32 adopts a dual-group symmetrical layout, placed on the left and right side walls of the support part 11. This design supports one-handed operation. By pressing the push button assembly 32, the stop block 31 is controlled to retract synchronously, and the other hand can hold the nebulizer 2 to perform insertion and removal. Compared with the traditional two-hand unlocking operation, the force required is reduced. The ergonomic optimization significantly improves the operating efficiency of medical staff, and is especially suitable for rapid equipment switching in emergency scenarios.

[0068] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made to the above embodiments by those skilled in the art after reading this specification are all within the scope of protection of the present invention. The various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, the embodiments of the present invention will not further describe various possible combinations.
