Description

Technical Field

[0001] This invention relates to the field of assistive medical devices, specifically a nasal irrigator with a heating function. Background Technology

[0002] Nasal irrigation, a common method of nasal cleaning and adjunctive treatment, effectively removes dust, allergens, and secretions from the nasal cavity, relieving symptoms such as nasal congestion and rhinitis. Existing nasal irrigation devices typically connect to the user's nasal cavity via a connector. However, due to differences in the shape and size of different users' nasal cavities, fixed or rigid connectors often fail to achieve a good seal, easily leading to leakage of the cleaning solution during irrigation. This reduces the irrigation effect and affects the user experience.

[0003] Furthermore, traditional rinsing solution heating methods typically involve heating the entire solution to the set temperature. This method not only has a long heating time and high energy consumption, but also easily leads to unstable temperatures, causing the rinsing solution to be too cold or too hot, resulting in user discomfort and even irritation to the nasal mucosa. During continuous use, it is also more prone to temperature decay or failure to quickly regain warmth.

[0004] Therefore, there is an urgent need for a nasal irrigation device that can adapt to different nasal cavity structures, reduce leakage, and efficiently and stably generate warm irrigation fluid to improve the comfort, safety, and energy efficiency of use.

[0005] Therefore, a nasal irrigator with a heating function is provided to address the above-mentioned problems. Summary of the Invention

[0006] In order to solve the problems of poor sealing and adaptability of existing nasal irrigation devices, low efficiency of overall heating method, unstable temperature, easy leakage of cleaning fluid and discomfort during use, the present invention provides a nasal irrigator with heating function.

[0007] The present invention solves the above-mentioned technical problems through the following technical solutions:

[0008] The present invention provides a nasal irrigator with a heating function, comprising a waste liquid shell, a mounting shell fixed to the top of the waste liquid shell, a liquid storage shell fixed to the top of the mounting shell, and a bearing shell fixed to the outer wall of the mounting shell;

[0009] The supporting shell is provided with two symmetrically distributed connecting components, which can extend into two nasal cavities respectively, and the volume of the contact area between the connecting components and the nasal cavity is variable.

[0010] A liquid inlet assembly is installed in the inner cavity of the mounting shell. One end of the liquid inlet assembly is connected to the inner cavity of the liquid storage shell, and the other end is connected to one of the connecting components.

[0011] A liquid discharge assembly is disposed in the inner cavity of a waste liquid shell or an installation shell. One end of the liquid discharge assembly is connected to another connecting assembly, and the other end is located in the inner cavity of the waste liquid shell.

[0012] The liquid inlet assembly is connected to the corresponding connecting assembly through the heating and mixing assembly. The heating and mixing assembly includes a two-way heating section, which heats a portion of the cleaning liquid.

[0013] The user's two nasal cavities are each connected to two connecting components, which have variable-volume contact areas to improve fit within the nasal cavity. A two-way heating unit heats only a portion of the cleaning fluid and mixes it with room-temperature cleaning fluid to obtain a warm cleaning fluid. This avoids discomfort caused by excessively low temperatures, while also improving heating efficiency and ensuring a continuous supply of warm cleaning fluid.

[0014] In this technical solution, the liquid inlet assembly includes a first pump body, a first liquid inlet pipe is connected to the liquid inlet port of the first pump body, the first liquid inlet pipe is connected to the bottom of the conical liquid guide cover, the liquid guide cover covers the liquid outlet, and the liquid outlet communicates with the inner cavity of the liquid storage shell and the mounting shell, that is, the liquid outlet is opened on the bottom side wall of the liquid storage shell and the top side wall of the mounting shell.

[0015] A two-way heating section is connected to the liquid outlet port of the first pump body. The two-way heating section is connected to the second connecting pipe or to the second connecting pipe through a mixing section.

[0016] The second connecting pipe is connected to the corresponding connecting component.

[0017] The first pump draws the cleaning fluid from the storage tank into the two-way heating section, where the cleaning fluid is both diverted and heated.

[0018] In this technical solution, the two-way heating section includes a branch pipe and a heating pipe connected to the liquid outlet port of the first pump body. The other ends of the branch pipe and the heating pipe are interconnected and connected to the mixing section or the second connecting pipe.

[0019] The diameter of the branch pipe is larger than the diameter of the heating pipe.

[0020] An electric heating wire is installed on the inner cavity or side wall of the heating tube.

[0021] The water in the outlet of the first pump body flows into the heating branch and the normal temperature branch, respectively, that is, into the branch pipe and the interior of the heating pipe. The cleaning fluid flowing through the interior of the heating pipe is heated by the electric heating wire in the heating pipe.

[0022] The mixing section includes a long strip-shaped mixing shell, one end of which is connected to the two-way heating section via a second connecting pipe, and the other end of which is connected to one of the corresponding connecting components via a second connecting pipe.

[0023] The inner cavity of the mixing shell is provided with multiple evenly distributed flow-blocking components.

[0024] The cleaning fluid at room temperature and after being heated enter the mixing tank. The long-stroke mixing tank and the flow-blocking components inside the mixing tank mix the flowing cleaning fluid.

[0025] In this technical solution, the liquid discharge assembly includes a second pump body, the inlet port and the outlet port of the second pump body are respectively connected to a second inlet pipe and an outlet pipe, the second inlet pipe is connected to one of the corresponding connecting components, and the end of the outlet pipe extends into the inner cavity of the waste liquid shell.

[0026] The waste liquid shell is equipped with a drain port or drain pipe with a valve.

[0027] When the liquid outlet assembly is installed in the inner cavity of the mounting housing, the second pump body is installed in the inner cavity of the mounting housing, the second liquid inlet pipe passes through the side wall of the mounting housing and the side wall of the bearing housing in sequence, and the liquid outlet pipe passes through the side wall of the mounting housing and the side wall of the waste liquid housing in sequence.

[0028] In this technical solution, the connecting component includes an installation tube, which is fixed on the bearing shell and is connected to the heating mixing component or the liquid outlet component, that is, the installation tube is connected to the second connecting tube or the second liquid inlet tube.

[0029] A liquid guiding tube is fixed to the end of the installation tube, and a nasal plug is sleeved on the outer wall of the liquid guiding tube.

[0030] The nasal plug is surrounded by an annular airbag, which is connected to a drive assembly that can inflate it.

[0031] By inflating the annular airbag with gas, the enlarged annular airbag fits more closely to the nasal cavity wall.

[0032] Liquid enters and exits the installation tube through a liquid guide tube.

[0033] In this technical solution, the driving component includes two symmetrically arranged driving units, which are respectively arranged corresponding to two connecting components. Each driving unit includes an inflation part and a driving part, and the driving part drives the inflation part to operate, thereby inflating the annular airbag.

[0034] The inflator is driven by the drive unit to inflate the annular airbag.

[0035] In this technical solution, the driving part includes a support rod, which is connected to the outer wall of the mounting shell through a retractable first guide rod. A movable plate is installed at the end of the support rod away from the connecting component, and an inflatable part that can overlap with the movable plate is provided on the side of the movable plate close to the mounting shell.

[0036] The bearing rod and the mounting tube are arranged parallel to each other. A first spring is sleeved on the surface of the first guide rod, and the two ends of the first spring are respectively connected to the two ends of the outer side of the first guide rod.

[0037] In this technical solution, the inflation part includes an inflation cylinder, which is arranged parallel to the first guide rod and fixed to the mounting shell by a mounting rod. A piston is slidably connected in the inner cavity of the inflation cylinder, and the piston and the inner wall of the inflation cylinder are slidably sealed. A transmission rod is fixed at the center of the piston surface, and a push plate is fixed at the other end of the transmission rod extending out of the inflation cylinder. The push plate can overlap with the moving plate. A second spring is sleeved on the surface of the transmission rod, and the two ends of the second spring are fixed to the transmission rod and the inflation cylinder, respectively.

[0038] The other end of the inflator is connected to one end of an air guide tube, and the other end of the air guide tube is connected to an annular airbag.

[0039] The movable plate is fixed with an overlapping arc plate for placing the thumb.

[0040] After the user inserts the nasal plug and the ring-shaped airbag on the nasal plug into the nasal cavity, the user presses the thumbs of both hands on the overlapping arc plate and then presses towards one side of the bearing shell. The moving plate and the bearing shell move towards one side of the bearing shell in sync, the first guide rod retracts, and at this time the first spring also deforms.

[0041] This technical solution also includes a protective component, which comprises two symmetrically arranged protective units, each of which is fitted around the nasal plug of the two connecting components.

[0042] The two protective units are respectively connected to the two drive units for mutual transmission, and the drive units drive the protective units to detach from the periphery of the nasal plug.

[0043] The protective unit provides simple protection for the part of the connecting assembly that is inserted into the nasal cavity.

[0044] During the inflation of the annular airbag, the drive assembly first moves the protective unit away from the periphery of the nasal plug, thus allowing the protective unit to be removed while the airbag is being inflated. This prevents the protective component from affecting the nasal plug and the annular airbag from entering the nasal cavity. The removal of the protective component and the inflation of the airbag are carried out simultaneously, making it convenient for the operator to use.

[0045] In this technical solution, the protective unit includes a protective shell, which is fitted around the nose plug, and the two side walls of the protective shell distributed along the length of the mounting rod are hollow.

[0046] The surface of the perforated structure of the protective shell on the side away from the supporting shell is covered with a soft shielding layer, which is slidably connected to the side wall of the protective shell through a sliding part;

[0047] The end of the shielding layer is connected to the transmission part, and the transmission part is connected to the drive unit.

[0048] By using a protective shell and a soft shielding layer, the surface of the nasal congestion can be protected, which can prevent dust from settling on the congestion to a certain extent. At the same time, a disinfection structure can be set on the protective shell.

[0049] In this technical solution, the sliding part includes two guide rails, both of which are inverted "L" shapes. The two ends of the shielding layer are respectively fixed with a first slide rod and a second slide rod. The two ends of the first slide rod and the two ends of the second slide rod are slidably connected to the two guide rails. The first slide rod is connected to the tensioning member, and the second slide rod is connected to the transmission part. The first slide rod and the second slide rod are respectively fixed to the two ends of the shielding layer. By sliding the first slide rod and the second slide rod on the guide rails, the shielding layer moves and no longer covers the hollow area of ​​the supporting shell.

[0050] The guide rail is fixed to the inner wall of the protective shell, and evenly distributed ultraviolet disinfection lamps can be installed inside the protective shell.

[0051] In this technical solution, the transmission part includes a driven rod, which overlaps or is fixed to the surface of the transmission plate on the end of the bearing rod. When the driven rod overlaps with the transmission plate, the driven rod is located on the side of the transmission plate closer to the bearing shell. A traction rod is fixed to the end of the driven rod. The traction rod is fixed on the second slide rod and is located in the inner cavity of the protective shell. The traction rod is arranged parallel to the first guide rod. A limit sleeve is sleeved on the surface of the traction rod and the limit sleeve is fixed to the side wall of the protective shell.

[0052] The tensioning element includes two winding wheels mounted on the outer wall of the protective shell. The winding wheels are rotatable and are equipped with torsion springs. A handwheel winds up a winding traction rope, and the free end of the traction rope passes through the side wall of the protective shell and is connected to the end of the first sliding rod.

[0053] The soft shielding layer is tensioned by the action of torsion springs and winding wheels, so that the shielding layer remains taut when moving and can return to its original position.

[0054] In this technical solution, two protective shells are connected to the bearing shell through a limiting part. The limiting part includes a synchronizing rod, the two ends of which are fixedly connected to the two protective shells respectively. The synchronizing rod is connected to the bearing shell through a telescopic second guide rod, and the second guide rod and the first guide rod are arranged parallel to each other.

[0055] A third spring is fitted onto the surface of the second guide rod.

[0056] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of the present invention.

[0057] The positive and progressive effects of this invention are as follows:

[0058] This invention provides independent connecting components for each of the user's two nasal cavities, and designs the contact area between the connecting components and the nasal cavities as a variable-volume structure. This allows the connecting components to automatically adapt to the shape and size of the nasal cavities, enhancing sealing and stability, effectively reducing leakage of cleaning fluid during rinsing, and improving rinsing efficiency and comfort.

[0059] This invention employs a two-way heating method, dividing the flowing cleaning fluid into a heating branch and a room-temperature branch. Only a portion of the cleaning fluid in the heating branch is rapidly heated to a high temperature before being mixed with the cleaning fluid in the room-temperature branch, resulting in a warm mixture for rinsing. This method avoids directly heating all the cleaning fluid, significantly improving heating efficiency, shortening heating time, and preventing nasal discomfort caused by excessively low rinsing fluid temperature.

[0060] By heating only a portion of the cleaning solution and mixing it with room temperature cleaning solution, a consistently warm rinsing solution can be generated to meet the needs of long-term rinsing, while reducing energy consumption and extending the device's battery life. At the same time, it avoids excessively high temperatures from irritating the nasal mucosa, thus improving the safety and comfort of use. Attached Figure Description

[0084] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments.

[0085] like Figure 1 and Figure 2 As shown, a nasal irrigator with heating function includes a waste liquid shell 1, a mounting shell 2 fixed to the top of the waste liquid shell 1, a liquid storage shell 3 fixed to the top of the mounting shell 2, and a bearing shell 21 fixed to the outer wall of the mounting shell 2.

[0086] The support shell 21 is provided with two symmetrically distributed connecting components 7, which can be inserted into two nasal cavities respectively, and the volume of the contact area between the connecting component 7 and the nasal cavity is variable.

[0087] Liquid inlet assembly 4 is installed in the inner cavity of the mounting shell 2. One end of the liquid inlet assembly 4 is connected to the inner cavity of the liquid storage shell 3, and the other end is connected to one of the connecting components 7.

[0088] Liquid discharge assembly 5 is disposed in the inner cavity of waste liquid shell 1 or mounting shell 2. One end of the liquid discharge assembly 5 is connected to another connecting assembly 7, and the other end is located in the inner cavity of waste liquid shell 1.

[0089] The liquid inlet assembly 4 is connected to the corresponding connecting assembly 7 through the heating and mixing assembly 6. The heating and mixing assembly 6 includes a two-way heating section, which heats a portion of the cleaning liquid.

[0090] The top of the liquid storage shell 3 is provided with a liquid filling pipe or a liquid filling port, and the liquid filling pipe or liquid filling port is covered with a detachable cover plate 31. The cover plate 31 is threaded or rotatably connected to the liquid filling pipe or liquid filling port.

[0091] Cleaning fluid is added to the inside of the reservoir 3 through the filling tube or filling port. The user's two nasal cavities are respectively connected to two connecting components 7, that is, the connecting components 7 extend into the nasal cavity. The first pump body 43 and the second pump body 51 are activated. The first pump body 43 draws the rinsing fluid from the inner cavity of the reservoir 3 into the connecting component 7, and flushes into the inside of one nasal cavity through the connecting component 7, and flows out from the other nasal cavity. The second pump body 51 draws the liquid flowing out from the corresponding nasal cavity into the inner cavity of the waste liquid shell 1, thus completing the rinsing of the nasal cavity.

[0092] In this application, the user's two nasal cavities are respectively connected to two connecting components 7, and the connection between the connecting components 7 and the nasal cavities is made tighter through the contact area with variable volume.

[0093] A portion of the cleaning fluid is heated by a two-way heating unit. The heated cleaning fluid is then mixed with the room-temperature cleaning fluid to form a warm cleaning fluid, thus avoiding the cleaning fluid temperature being too low and causing discomfort to the user.

[0094] By heating a small portion of the cleaning solution and then mixing it, a warm cleaning solution is obtained. This process improves heating efficiency and allows for the continuous generation of warm cleaning solution.

[0095] Example 1

[0096] like Figure 6 As shown, the liquid inlet assembly 4 includes a first pump body 43, and a first liquid inlet pipe 42 is connected to the liquid inlet port of the first pump body 43. The first liquid inlet pipe 42 is connected to the bottom of the conical liquid guide cover 41. The liquid guide cover 41 covers the liquid outlet 32. The liquid outlet 32 ​​communicates the inner cavity of the liquid storage shell 3 and the mounting shell 2. That is, the liquid outlet 32 ​​is opened on the bottom side wall of the liquid storage shell 3 and the top side wall of the mounting shell 2.

[0097] A two-way heating section is connected to the liquid outlet port of the first pump body 43. The two-way heating section is connected to the second connecting pipe 65 or to the second connecting pipe 65 through a mixing section.

[0098] The second connecting pipe 65 is connected to the corresponding connecting component 7.

[0099] The first pump body 43 draws the cleaning fluid in the storage tank 3 into the two-way heating section, where the cleaning fluid is heated and circulated through the two-way heating section.

[0100] Specifically, such as Figure 7 As shown, the two-way heating section includes a branch pipe 61 and a heating pipe 62 connected to the liquid outlet port of the first pump body 43. The other ends of the branch pipe 61 and the heating pipe 62 are interconnected and connected to the mixing section or the second connecting pipe 65.

[0101] The diameter of the branch pipe 61 is larger than the diameter of the heating pipe 62, meaning that the cleaning liquid passing through the heating branch is a small portion. Preferably, twice the diameter of the heating pipe 62 is less than the diameter of the heating pipe 62.

[0102] An electric heating wire is provided on the inner cavity or side wall of the heating tube 62.

[0103] The water in the outlet of the first pump body 43 flows into the heating branch and the normal temperature branch respectively, that is, into the branch pipe 61 and the heating pipe 62. The cleaning fluid flowing through the heating pipe 62 is heated by the electric heating wire in the heating pipe 62.

[0104] Furthermore, the mixing section includes a long strip-shaped mixing shell 64, one end of which is connected to the two-way heating section via a second connecting pipe 65, and the other end is connected to one of the corresponding connecting components 7 via a second connecting pipe 65.

[0105] The inner cavity of the mixing shell 64 is provided with a plurality of evenly distributed flow-blocking elements 66.

[0106] The room-temperature cleaning fluid and the heated cleaning fluid enter the mixing tank 64 separately. The mixing tank 64 has a relatively long flow path, allowing the two liquids sufficient mixing distance within the tank. Multiple flow-blocking elements 66 are installed inside the mixing tank 64. These elements can change the flow direction, generate turbulence, and prolong the residence time of the liquid within the tank during flow, thereby promoting thorough mixing of the room-temperature and heated cleaning fluids. This ensures a uniform and stable temperature of the output rinsing fluid, preventing discomfort to the user caused by excessively high or low local temperatures.

[0107] like Figure 7 As shown, the shape of the mixing shell 64 is preferably a shape with a long internal travel, specifically an arc shape or a spiral shape.

[0108] The flow obstruction element 66 is a flow obstruction component that is evenly distributed along the liquid flow direction. It is preferably a rotating wheel installed on the side wall of the mixing shell 64. Multiple blades arranged in a ring array are fixed on the annular surface of the rotating wheel. The blades are arranged in a direction perpendicular to the liquid flow.

[0109] As the flowing cleaning fluid passes over the blades, it pushes the blades to move, thereby generating eddies.

[0110] Specifically, the liquid outlet assembly 5 includes a second pump body 51, the inlet port and the outlet port of the second pump body 51 are respectively connected to a second inlet pipe 52 and an outlet pipe 53, the second inlet pipe 52 is connected to one of the corresponding connecting components 7, and the end of the outlet pipe 53 extends into the inner cavity of the waste liquid shell 1.

[0111] Waste liquid shell 1 is equipped with a drain port or drain pipe with a valve.

[0112] When the liquid outlet assembly 5 is installed in the inner cavity of the mounting shell 2, the second pump body 51 is installed in the inner cavity of the mounting shell 2, the second liquid inlet pipe 52 passes through the side wall of the mounting shell 2 and the bearing shell 21 in sequence, and the liquid outlet pipe 53 passes through the side wall of the mounting shell 2 and the side wall of the waste liquid shell 1 in sequence.

[0113] like Figure 6 As shown, when the liquid outlet assembly 5 is installed in the inner cavity of the waste liquid shell 1, the second pump body 51 is installed in the inner cavity of the waste liquid shell 1, the second liquid inlet pipe 52 passes through the waste liquid shell 1 in sequence, passes through the side walls of the mounting shell 2 and the bearing shell 21 on both sides, and the liquid outlet pipe 53 is located in the inner cavity of the waste liquid shell 1.

[0114] The second pump body 51 draws out the cleaning fluid and directs it into the waste liquid shell 1.

[0115] Example 2

[0116] like Figure 2 As shown, the connecting component 7 includes an installation tube 71, which is fixed on the bearing shell 21. The installation tube 71 is connected to the heating mixing component 6 or the liquid outlet component 5, that is, the installation tube 71 is connected to the second connecting tube 65 or the second liquid inlet tube 52.

[0117] A liquid guiding tube 73 is fixed to the end of the installation tube 71, and a nasal plug 72 is sleeved on the outer wall of the liquid guiding tube 73.

[0118] The nasal plug 72 is surrounded by an annular airbag 74, which is connected to a drive assembly 8 that can be inflated.

[0119] By inflating the annular airbag 74 with gas, the enlarged annular airbag 74 fits more closely to the nasal cavity wall.

[0120] Liquid enters and exits the mounting tube 71 through the liquid guide tube 73.

[0121] The drive assembly 8 includes two symmetrically arranged drive units, which are respectively arranged in relation to two connecting assemblies 7. Each drive unit includes an inflation part and a drive part. The drive part drives the inflation part to operate, thereby inflating the annular airbag 74.

[0122] The inflation unit is driven by the drive unit to inflate the annular airbag 74.

[0123] Specifically, the drive unit includes a support rod 81, which is connected to the outer wall of the mounting shell 2 via a retractable first guide rod 83. A movable plate 82 is installed at the end of the support rod 81 away from the connecting component 7, and an inflatable part that can be attached to the side of the movable plate 82 near the mounting shell 2 is provided.

[0124] The bearing rod 81 and the mounting tube 71 are arranged parallel to each other. A first spring is sleeved on the surface of the first guide rod 83, and the two ends of the first spring are respectively connected to the two ends of the outer side of the first guide rod 83.

[0125] Furthermore, the inflation part includes an inflation cylinder 84, which is arranged parallel to the first guide rod 83 and fixed to the mounting shell 2 by a mounting rod 841. A piston is slidably connected in the inner cavity of the inflation cylinder 84, and the piston and the inner wall of the inflation cylinder 84 are slidably sealed. A transmission rod 85 is fixed at the center of the piston surface. The other end of the transmission rod 85 extends out of the inflation cylinder 84 and is fixed with a push plate 86. The push plate 86 can overlap with the moving moving plate 82. A second spring is sleeved on the surface of the transmission rod 85, and the two ends of the second spring are respectively fixed to the transmission rod 85 and the inflation cylinder 84.

[0126] The other end of the air cylinder 84 is connected to one end of the air guide tube 87, and the other end of the air guide tube 87 is connected to the annular airbag 74.

[0127] An overlapping arc plate 821 for placing the thumb is fixed on the movable plate 82.

[0128] After the user inserts the nasal plug 72 and the annular airbag 74 on the nasal plug 72 into the nasal cavity, the user presses the overlapping arc plate 821 with the thumbs of both hands, and then presses it towards one side of the bearing shell 21. The moving plate 82 and the bearing move towards one side of the bearing shell 21 in sync, the first guide rod 83 retracts, and the first spring also deforms at this time.

[0129] After the moving plate 82 moves to the push plate 86, it pushes the push plate 86 to move towards one side of the bearing shell 21, thereby driving the piston to move synchronously through the transmission rod 85, thereby pressing the air in the air cylinder 84 into the annular airbag 74 until the user feels the annular airbag 74 repeatedly fitting against the nasal cavity. During the above process, the second spring deforms, accumulating elastic potential energy for the subsequent reset of the transmission rod 85.

[0130] Then turn on the device. The control switch for turning on the device is preferably located on the outer wall of the carrier housing 21 or on the outer wall of the mounting housing 2 of the carrier housing 21.

[0131] Example 3

[0132] like Figures 8-13 As shown, it also includes a protective component 9, which includes two symmetrically arranged protective units, each of which is fitted around the nasal plug 72 of the two connecting components 7.

[0133] The two protective units are respectively connected to the two drive units for mutual transmission, and the drive units drive the protective units to detach from the periphery of the nasal plug 72.

[0134] The protective unit provides simple protection for the part of the connecting assembly 7 that is used to extend into the nasal cavity.

[0135] During the inflation of the annular airbag, when the drive assembly 8 is running, it first drives the protective unit to detach from the periphery of the nasal plug 72, so that the protective unit is removed while the airbag is being inflated, thus preventing the protective assembly 9 from affecting the nasal plug 72 and the annular airbag 74 from entering the nasal cavity. The removal of the protective assembly 9 and the inflation of the airbag are carried out simultaneously, which is convenient for the operator to use.

[0136] During the inflation of the annular inflatable nasal bag, the drive assembly 8 first detaches the protective unit from the periphery of the nasal plug 72, ensuring its removal before inflation begins. This design synchronizes the removal of the protective unit with the inflation process, guaranteeing smooth insertion of the inflatable nasal bag while preventing the protective assembly 9 from obstructing or interfering with the nasal plug 72 and the annular inflatable nasal bag during inflation and insertion. This synchronized operation reduces operator steps, improves ease of use and efficiency, lowers the risk of misoperation, and enhances the stability of the device's positioning within the nasal cavity and user comfort.

[0137] The protective unit includes a protective shell 91, which is fitted around the nose plug 72. The two side walls of the protective shell 91, which are distributed along the length of the mounting rod 841, are hollow.

[0138] The surface of the perforated structure of the protective shell 91 on the side away from the supporting shell 21 is covered with a soft shielding layer 97, which is slidably connected to the side wall of the protective shell 91 via a sliding part.

[0139] The end of the shielding layer 97 is connected to the transmission part, and the transmission part is connected to the drive unit.

[0140] The protective shell 91 and the soft shielding layer 97 protect the surface of the nasal plug 72, which can prevent dust from falling on the nasal plug 72 to a certain extent. At the same time, a disinfection structure can be set on the protective shell 91.

[0141] like Figure 10 As shown, the sliding part includes two guide rails 92, both of which are inverted "L" shapes. The two ends of the shielding layer 97 are respectively fixed with a first slide rod 93 and a second slide rod 94. The two ends of the first slide rod 93 and the two ends of the second slide rod 94 are slidably connected to the two guide rails 92. The first slide rod 93 is connected to the tensioning member, and the second slide rod 94 is connected to the transmission part. The first slide rod 93 and the second slide rod 94 are respectively fixed to the two ends of the shielding layer 97. By sliding the first slide rod 93 and the second slide rod 94 on the guide rails 92, the shielding layer 97 moves and no longer covers the hollow area of ​​the bearing shell 21.

[0142] The guide rail 92 is fixed on the inner wall of the protective shell 91, and evenly distributed ultraviolet disinfection lamps can be installed inside the protective shell 91.

[0143] like Figure 13 As shown, the transmission part includes a driven rod 961, which overlaps or is fixed to the surface of the transmission plate 99 on the end of the bearing rod 81. When the driven rod 961 overlaps with the transmission plate 99, the driven rod 961 is located on the side of the transmission plate 99 closer to the bearing shell 21. A traction rod 96 is fixed to the end of the driven rod 961. The traction rod 96 is fixed on the second slide rod 94 and is located in the inner cavity of the protective shell 91. The traction rod 96 is arranged parallel to the first guide rod 83. A limit sleeve is sleeved on the surface of the traction rod 96 and the limit sleeve is fixed on the side wall of the protective shell 91.

[0144] The tensioning element includes two winding wheels 95 mounted on the outer wall of the protective shell 91. The winding wheels 95 are rotatable and are equipped with torsion springs. A handwheel winds up a winding traction rope, and the free end of the traction rope passes through the side wall of the protective shell 91 and is connected to the end of the first slide bar 93.

[0145] The soft shielding layer 97 is tensioned by the action of the torsion spring and the winding wheel 95, so that the shielding layer 97 remains taut when moving and can return to its original position.

[0146] When the moving plate 82 moves, it drives the driven rod 961 to move synchronously toward one side of the bearing shell 21 through the bearing shaft and the transmission plate 99. The moving driven rod 961 drives the second slide rod 94 to slide on the guide rail 92 through the traction rod 96, thereby driving the shielding layer 97 and the first slide rod 93 to move synchronously. The winding wheel 95 also rotates, and the traction rope wound on its surface begins to unwind. The torsion spring deforms until the first slide rod 93 slides to the corner of the guide rail 92, at which point the first slide rod 93 and the second slide rod no longer move.

[0147] In the initial state, the first slide bar 93 is located on one of the right-angled sides of the guide rail 92, and the second slide bar 94 is located on the other right-angled side of the guide rail 92. The second slide bar 94 is located on the right-angled side of the guide rail 92 and is set parallel to the first guide bar 83.

[0148] A fourth spring is preferably sleeved on the surface of the traction rod 96. When the traction rod 96 moves, the fourth spring deforms, and the two ends of the fourth spring are fixed to the traction rod 96 and the limiting sleeve, respectively.

[0149] Two protective shells 91 are connected to the bearing shell 21 through a limiting part. The limiting part includes a synchronizing rod 98. The two ends of the synchronizing rod 98 are fixedly connected to the two protective shells 91 respectively. The synchronizing rod 98 is connected to the bearing shell 21 through a telescopic second guide rod 981. The second guide rod 981 and the first guide rod 83 are arranged parallel to each other.

[0150] A third spring is fitted onto the surface of the second guide rod 981.

[0151] Furthermore, the spring constant of the torsion spring is less than that of the third spring.

[0152] When the first slide bar 93 moves to its limit position (the corner of the guide rail 92, where the angle of the corner limits the first slide bar 93, or a limiting rod is installed inside the corner of the guide rail 92), the moving plate 82 continues to move, thereby driving the entire protective shell 91 to move towards one side of the bearing shell 21 until the protective shell 91 is separated from the periphery of the nasal plug 72 and no longer affects the insertion of the nasal plug 72 and the annular airbag 74 into the nasal cavity.

[0153] Then, after the relevant structure is inserted into the nasal cavity, the moving plate 82 continues to move, and the moving plate 86 is moved by the moving plate 82 to inflate the annular airbag 74.

[0154] During the above process, the second guide rod 981 contracts and the third spring deforms, accumulating elastic potential energy for the reset of the second guide rod 981.

[0155] During the above process, since the amount of gas required to inflate the annular airbag 74 is relatively small, the travel distance for moving the entire protective shell 91 will not be too long, thus not placing too much load on the user.

[0156] This invention is not limited to the embodiments described above. Any changes in shape or structure shall fall within the protection scope of this invention. The protection scope of this invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of this invention, but all such changes and modifications shall fall within the protection scope of this invention.
