Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an auxiliary device for administering a projectile aerosol and its method of use. Background Technology

[0002] Conventional aerosol delivery devices that utilize high-temperature atomization employ heating to atomize the aerosol, combined with oral respiration and a pneumatic mechanism. However, the high-temperature heating process can easily damage the molecular structure of the substances in the aerosol, and may even cause chemical reactions that generate harmful substances, affecting the intended effect or even causing harm. In addition, high-temperature aerosol generators require electric heating and repeated charging to ensure continuous operation, which is inconvenient to some extent. Battery heating and high-temperature heating processes also pose certain safety concerns.

[0003] Aerosol delivery equipment that uses ultrasonic atomization works by atomizing liquid through ultrasonic vibrations and adding a fan to deliver the aerosol. When ultrasound propagates through a medium, the high frequency of vibration of the medium particles results in high energy, easy concentration, and strong directionality, thus exerting a powerful effect on matter that the human body cannot withstand. Long-term exposure to an ultrasonic environment can damage the human body, especially delicate organs, and in severe cases, can be fatal. Therefore, ultrasonic products are not suitable for long-term or continuous use. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides an auxiliary device for projectile aerosol delivery and its usage method, thus solving the problems mentioned in the background section.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: an auxiliary device for dispensing projectile aerosols and its method of use, comprising a housing, a round cover at the top of the housing, a metal frame at the top of the inner cavity of the housing, a metal injection pipe at the top of the metal frame, a storage compartment connected to the metal frame in the inner cavity of the housing, and a spring valve communicating with the storage compartment on the metal frame. A metal connecting pipe located at the center of the metal frame is attached to the top of the spring valve. The metal injection pipe and the metal connecting pipe are misaligned, and the metal injection pipe is connected to the storage compartment via a flexible hose. The metal connecting pipe is connected, and a spring is provided at the rear bottom end of the metal frame. The top of the spring is provided with a switch valve with a cross-section in the shape of a number 7. The bottom of the round cover abuts against the top of the switch valve. The top of the switch valve is attached to a linkage plate with a cross-section in the shape of a number C. The bottom of the linkage plate is forked, and the forked part of the linkage plate clamps the outer wall of the metal connecting pipe. An opening is provided at the bottom end of the housing, and a pressure pushing spring device located in the storage compartment is provided on the opening. The bottom of the pressure pushing spring device is provided with a connection hole, and the storage compartment is filled with liquid aerosol.

[0008] To prevent the pressure-driven spring device from falling off, preferably, a connecting block connected to the side wall of the pressure-driven spring device is fixed inside the storage compartment.

[0009] In order to effectively strengthen the connection between the pressure-driven spring device and the connecting block, preferably, the outer wall of the pressure-driven spring device is provided with a meshing groove corresponding to the position of the connecting block, and the side wall of the connecting block is provided with meshing teeth.

[0010] To facilitate timely replenishment of the storage compartment via pressure-driven spring device and connecting hole, preferably, a water level meter is provided on the outer wall of the housing, and the water level meter is connected to the storage compartment.

[0011] To effectively prevent the connection between the metal connecting pipe and the linkage plate from falling off, preferably, the outer wall of the metal connecting pipe is provided with a protrusion to facilitate the connection of the linkage plate.

[0012] To prevent the valve from shifting back and forth during the lifting and lowering process, preferably, the slide groove has symmetrical guide frames on the upper part, and the left and right sides of the top of the valve are provided with guide grooves that cooperate with the guide frames.

[0013] The steps for using this invention are as follows:

[0014] Step 1: When using the product, first open the round cover, then place the metal spray tube into the nasal cavity or mouth. After the round cover is opened, the spring causes the switch valve to rise. During the rising process, the switch valve lifts the metal connecting tube through the linkage plate. A gap is created at the contact point between the metal connecting tube and the spring valve. Then, outside air enters the storage chamber through the gap and the spring valve. The liquid aerosol in the storage chamber changes due to the air pressure and is delivered to the metal spray tube through the metal connecting tube and the hose. The metal spray tube then delivers the aerosol into the nasal cavity or mouth.

[0015] Step 2: When stopping use, reset and close the round cover, then press down the valve to release the tension on the linkage plate. The metal connecting pipe will reset, the gap will be sealed, and the aerosol will stop vaporizing.

[0016] Step 3: Users can observe the remaining capacity of the liquid aerosol stored inside the storage compartment using the water level gauge;

[0017] Step 4: In the event of a shortage of liquid aerosol stored inside the storage chamber, connect the container containing the liquid aerosol to the connection hole, and then use pressure to push the spring device to create an opening, allowing the liquid aerosol to enter the storage chamber for storage.

[0018] Step 5: When not filling any aerosol, it can be used as an auxiliary tool for all propellant-based aerosol products.

[0019] (III) Beneficial Effects

[0020] Compared with the prior art, the present invention provides an auxiliary device for the application of projectile aerosols and its method of use, which has the following beneficial effects:

[0021] 1. This is a projectile aerosol delivery auxiliary device and its usage method. When using the device, the user first opens the round cap, then places the metal spray tube into the nasal cavity or mouth. After the round cap opens, a spring causes the switch valve to rise. During the rising process, the switch valve lifts the metal connecting tube via a linkage plate, creating a gap at the contact point between the metal connecting tube and the spring valve. Outside air then enters the storage chamber through this gap and the spring valve. The liquid aerosol in the storage chamber changes pressure and is then delivered through the metal connecting tube and hose to the metal spray tube. The metal spray tube then delivers the aerosol into the nasal cavity or mouth, thus achieving the delivery of nasal and pharyngeal breathing, breath freshening, and electronic atomization products. Compared to high-temperature atomization or ultrasonic atomization, this method... Combining mouth-inhalation, nasal-inhalation, and fan-powered operation makes it more convenient, safer, and more effective. While high-temperature atomization and ultrasonic atomization require charging, projectile atomizers can be used without charging. Due to their working principles and usage methods, high-temperature atomization and ultrasonic atomization have certain limitations on usage scenarios, such as public places, high-speed trains, and airplanes. However, projectile atomizers can be used anytime and anywhere, reducing the risk of harmful substances from high-temperature chemical reactions, the impact of ultrasound on the human body, and the potential risks of battery charging and use. When not in use, the round cover is reset and closed. The round cover presses down the switch valve, which, through a linkage plate, lowers the metal connecting tube. After the metal connecting tube is in contact with the spring valve, the gap closes, and the aerosol stops vaporizing.

[0022] 2. This is an auxiliary device for supplying projectile aerosols and its usage method. The connecting block can prevent the pressure-driven spring device from falling off. The meshing groove and meshing teeth can effectively strengthen the connection between the pressure-driven spring device and the connecting block. The user can observe the remaining capacity of the liquid aerosol stored in the storage compartment through the water level gauge, so as to replenish the storage compartment in time through the pressure-driven spring device and the connecting hole. Since the outer wall of the metal connecting pipe is provided with a protrusion to facilitate the connection of the linkage plate, it can effectively prevent the connection between the metal connecting pipe and the linkage plate from falling off. The guide frame can effectively prevent the valve from shifting back and forth during the lifting and lowering process. Attached Figure Description

[0029] 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.

[0030] Please see Figure 1-5This invention provides a technical solution: It includes a housing 1, with a round cover at its top. A metal frame 2 is located at the top of the inner cavity of the housing 1, and a metal injection pipe 3 is located at the top of the metal frame 2. The inner cavity of the housing 1 has a storage compartment connected to the metal frame 2, and a spring valve 4 communicating with the storage compartment is provided on the metal frame 2. A metal connecting pipe 5 located at the center of the metal frame 2 is attached to the top of the spring valve 4. The metal injection pipe 3 is misaligned with the metal connecting pipe 5, and the metal injection pipe 3 communicates with the metal connecting pipe 5 via a flexible hose. A spring 6 is located at the rear bottom of the metal frame 2, and the top of the spring 6 has a cross-section... A 7-shaped switch valve 7 is present, with the bottom of the round cover abutting the top of the switch valve 7. A C-shaped linkage plate 8 is attached to the top of the switch valve 7. The bottom of the linkage plate 8 is forked, and the forked portion clamps the outer wall of the metal connecting pipe 5. An opening is provided at the bottom of the housing 1, and a pressure-driven spring device 9 located within the storage compartment is provided on the opening. The bottom of the pressure-driven spring device 9 has a connecting hole 10, and the storage compartment is filled with liquid aerosol. Therefore, when the user uses the device, they first open the round cover, then place the metal spray pipe 3 into the nasal cavity or mouth. After the round cover is opened, the spring 6... When valve 7 rises, it lifts metal connecting pipe 5 via linkage plate 8, creating a gap between the metal connecting pipe 5 and spring valve 4. Outside air then passes through this gap and enters the storage chamber via spring valve 4. The liquid aerosol in the storage chamber changes pressure and is then transported via metal connecting pipe 5 and hose to metal spray pipe 3. Metal spray pipe 3 then delivers the aerosol to the nasal cavity or mouth, thus enabling nasal and pharyngeal breathing, breath freshening, and electronic atomization products. Compared to high-temperature atomization, ultrasonic atomization, and combined mouth-inhalation, nasal-inhalation, and fan-driven methods, this is more convenient, safer, and more effective. Furthermore, high-temperature atomization... Both high-temperature atomization and ultrasonic atomization require charging for operation, but projectile atomization devices can be used without charging. Due to their working principles and usage methods, high-temperature atomization and ultrasonic atomization have certain limitations on the usage scenarios, such as public places, high-speed trains, and airplanes. However, projectile atomization devices can be used anytime and anywhere, and can also reduce the problems of harmful substances from high-temperature chemical reactions, the impact of ultrasound on the human body, and the potential risks of battery charging and use. When not in use, the round cover is reset and closed. The round cover causes the switch valve 7 to press down. The switch valve 7 drives the metal connecting tube 5 to descend through the linkage plate 8. After the metal connecting tube 5 is in contact with the spring valve 4, the gap is closed, and the aerosol stops vaporizing.

[0031] In this invention, a connecting block 11 is fixed inside the storage compartment and connected to the side wall of the pressure pushing spring device 9. As described above, the connecting block 11 can prevent the pressure pushing spring device 9 from falling off.

[0032] In this invention, the outer side wall of the pressure-driven spring device 9 is provided with a meshing groove corresponding to the position of the connecting block 11, and the side wall of the connecting block 11 is provided with meshing teeth. Through the above, the meshing groove and meshing teeth can effectively strengthen the connection between the pressure-driven spring device 9 and the connecting block 11.

[0033] In this invention, a water level meter 12 is provided on the outer wall of the housing 1, and the water level meter 12 is connected to the storage compartment. Through the above, the user can observe the remaining capacity of the liquid aerosol stored in the storage compartment through the water level meter 12, so as to replenish the storage compartment in a timely manner by pushing the spring device 9 and the connecting hole 10 with pressure.

[0034] In this invention, the outer side wall of the metal connecting pipe 5 is provided with a protrusion to facilitate the connection of the linkage piece 8. By providing the protrusion to facilitate the connection of the linkage piece 8 on the outer side wall of the metal connecting pipe 5, the connection between the metal connecting pipe 5 and the linkage piece 8 can be effectively prevented from falling off.

[0035] In this invention, the slide is symmetrically provided with guide frames 13, and the top left and right sides of the switch valve 7 are provided with guide grooves that cooperate with the guide frames 13. Through the above, the guide frames 13 can effectively prevent the switch valve 7 from shifting back and forth during the lifting and lowering process.

[0036] The steps for using this invention are as follows:

[0037] Step 1: When using the product, first open the round cover, then place the metal spray tube 3 into the nasal cavity or oral cavity. After the round cover is opened, the spring 6 causes the switch valve 7 to rise. During the rising process, the switch valve 7 lifts the metal connecting tube 5 through the linkage plate 8. A gap is created at the contact point between the metal connecting tube 5 and the spring valve 4. Then, outside air enters the storage chamber through the gap and the spring valve 4. The liquid aerosol in the storage chamber changes due to the change in air pressure and is delivered to the metal spray tube 3 through the metal connecting tube 5 and the hose. The metal spray tube 3 then delivers the aerosol into the nasal cavity or oral cavity.

[0038] Step 2: When stopping use, reset and close the round cover, then press down valve 7 to release the tension on the linkage plate 8, reset the metal connecting pipe 5, close the gap, and stop the aerosol from vaporizing.

[0039] Step 3: Users can observe the remaining capacity of the liquid aerosol stored inside the storage compartment through the water level gauge 12;

[0040] Step 4: In the event of a shortage of liquid aerosol stored inside the storage chamber, connect the container containing the liquid aerosol to the connection hole 10, and then use pressure to push the spring device 9 to form an opening, allowing the liquid aerosol to enter the storage chamber for storage.

[0041] Step 5: When not filling any aerosol, it can be used as an auxiliary tool for all propellant-based aerosol products.

[0042] In summary, this projectile aerosol dispensing auxiliary device and its usage method involve the user first opening the round cap, then placing the metal spray tube 3 into the nasal cavity or mouth. After the round cap opens, the spring 6 causes the switch valve 7 to rise. During the rising process, the switch valve 7 lifts the metal connecting tube 5 via the linkage plate 8, creating a gap at the contact point between the metal connecting tube 5 and the spring valve 4. Outside air then enters the storage chamber through this gap via the spring valve 4. The liquid aerosol in the storage chamber then changes due to the pressure change, flowing through the metal connecting tube 5 and the flexible tube... The aerosol is delivered to the metal jet tube 3, which then delivers it into the nasal cavity or mouth, enabling nasal and pharyngeal breathing, breath freshening, and electronic atomization products. Compared to high-temperature atomization, ultrasonic atomization, and combined mouth-to-nose, nasal, and fan-driven methods, this is more convenient, safer, and more effective. Furthermore, while high-temperature and ultrasonic atomization require charging, projectile atomization devices do not. Due to their operating principles and usage methods, high-temperature and ultrasonic atomization have certain limitations on their application scenarios, such as public places. While these devices can be used on high-speed trains, airplanes, etc., projectile atomizing devices can be used anytime and anywhere. They can also reduce the problems of harmful substances from high-temperature chemical reactions, the impact of ultrasound on the human body, and potential risks associated with battery charging and use. When not in use, the round cover is reset and closed, causing the switch valve 7 to press down. The switch valve 7 drives the metal connecting pipe 5 to descend through the linkage plate 8. After the metal connecting pipe 5 is in contact with the spring valve 4, the gap closes, and the aerosol stops atomizing. The connecting block 11 can prevent the pressure-driven spring device 9 from falling off. The meshing groove and meshing teeth can effectively strengthen the connection between the pressure-driven spring device 9 and the connecting block 11. Users can observe the remaining capacity of the liquid aerosol stored in the storage compartment through the water level meter 12, so as to replenish the storage compartment in time by pressing the spring device 9 and the connecting hole 10. Since the outer wall of the metal connecting pipe 5 has a protrusion that facilitates the connection of the linkage plate 8, it can effectively prevent the connection between the metal connecting pipe 5 and the linkage plate 8 from falling off. The guide frame 13 can effectively prevent the switch valve 7 from shifting back and forth during the lifting and lowering process.
