Description

Technical Field

[0001] The present application relates to the field of medical devices, and in particular, to an atomizer for an atomizing mask. Background Art

[0002] An atomizing mask provides an atomization requirement while wearing the mask by arranging an atomizer on the mask.

[0003] Most current atomizers use ultrasonic atomization to atomize the liquid medicine through ultrasonic waves for users to absorb. However, when the user exhales, the atomized liquid medicine inside the mask will also be carried out through the air outlet of the atomizing mask, resulting in waste of the liquid medicine. Summary of the Invention

[0004] In order to reduce the waste of liquid medicine, the present application provides an atomizer for an atomizing mask.

[0005] An atomizer for an atomizing mask provided by the present application adopts the following technical solutions:

[0006] An atomizer for an atomizing mask includes a body. An atomization module and an exhalation module are arranged on the body. An air inlet channel is arranged beside the atomization module on the body. The atomization module includes a liquid medicine chamber and an atomization element for atomizing and spraying the liquid medicine in the liquid medicine chamber. The exhalation module includes an air outlet channel arranged on the body. The exhalation module further includes an air outlet one-way valve arranged in the air outlet channel and used for restricting the outside air from entering the mask through the air outlet channel. The air outlet one-way valve uses the user's breath to open and close the air outlet channel. A sensor for detecting the opening and closing state of the air outlet one-way valve is arranged on one side of the air outlet one-way valve in the air outlet channel. The sensor obtains the opening and closing state of the air outlet one-way valve and sends the opening and closing state to a central controller. The central controller controls the opening and closing of the atomization element according to the opening and closing state.

[0007] By adopting the above technical solutions, when the user exhales, the air outlet one-way valve is opened under the action of the air pressure inside the mask, and the air exhaled by the user is discharged through the air outlet channel. When the user inhales, the air outlet one-way valve is closed, and the atomized liquid medicine is inhaled by the user together with the gas entering through the air inlet channel. The sensor can detect the opening and closing state of the air outlet one-way valve, thereby judging the user's breathing frequency and sending this information to the central controller. The central controller controls the opening and closing of the atomization element according to the user's breathing frequency, that is, when the user exhales, the atomization element is closed, and when the user inhales, the atomization element is opened, so as to reduce the discharge of the atomized liquid medicine through the air outlet channel and further reduce the waste of the liquid medicine.

[0008] Optionally, an air inlet one-way valve for restricting the gas inside the mask from entering the mask through the air inlet channel is arranged in the air inlet channel.

[0009] By adopting the above technical solution, an intake check valve is arranged inside the intake passage opening, which can prevent the atomized liquid medicine from being discharged through the intake passage, further reducing the waste of liquid medicine.

[0010] Optionally, the air outlet passage is inclined in the thickness direction of the device body, and the height of the air outlet passage gradually decreases from the inner side to the outer side of the device body; a spiral blade is arranged along the length direction of the air outlet passage outside the air outlet check valve; a liquid storage tank is arranged on the device body below the air outlet passage, and the liquid storage tank is communicated with one end of the air outlet passage close to the outer side of the device body.

[0011] By adopting the above technical solution, since the breathing lengths of each person are different, even if the atomizing element only starts during inhalation, there is still some atomized liquid medicine remaining inside the mask and being discharged outside the mask during exhalation, resulting in waste of liquid medicine. However, by arranging a spiral blade inside the air outlet passage, during exhalation, the gas can be directly discharged, while the liquid medicine is blocked by the spiral blade and intercepted, sliding down along the spiral blade to be collected in the liquid storage tank, thereby further reducing the waste of liquid medicine.

[0012] Optionally, the spiral blade is coated with a hydrophobic material.

[0013] By adopting the above technical solution, it is avoided that the liquid medicine adheres to the spiral blade.

[0014] Optionally, the liquid medicine bin is detachably connected to the device body. The liquid medicine bin includes a bin body and a communication pipe arranged on the bin body. The communication pipe communicates with the bin body. A liquid guide strip is arranged inside the communication pipe. One end of the liquid guide strip is located inside the liquid medicine bin, and the other end of the liquid guide strip is used to contact the vibrating piece of the atomizing element.

[0015] By adopting the above technical solution, it is convenient to set up a separate replaceable liquid medicine bin. During use, the liquid medicine bin is installed on the device body, and the liquid guide strip is made to contact the vibrating piece of the atomizing element, so that the liquid medicine in the liquid medicine bin can be atomized and ejected.

[0016] Optionally, a micro piezoelectric pump is installed inside the device body. The liquid inlet of the micro piezoelectric pump is communicated with the lower end of the liquid storage tank. The liquid outlet of the micro piezoelectric pump is communicated with and fixedly connected to an infusion pipe. An inlet is opened at the upper end of the bin body. A valve assembly is arranged inside the inlet. When the liquid medicine bin is installed on the device body, the end of the infusion pipe away from the micro piezoelectric pump is used to insert into the inlet and open the valve assembly to communicate with the liquid medicine bin.

[0017] By adopting the above technical solution, the micro piezoelectric pump can transport the liquid medicine collected in the liquid storage tank to the liquid medicine bin. When installing the liquid medicine bin, the infusion pipe is inserted into the inlet. During this process, the valve assembly is opened, and then the liquid medicine bin and the infusion pipe are communicated.

[0018] Optionally, the valve assembly includes an elastic sealing plug disposed in the liquid inlet for sealing the liquid inlet. A perforation for inserting an infusion tube is formed in the elastic sealing plug. When the elastic sealing plug is not deformed, the perforation is closed.

[0019] By adopting the above technical solution, during the process of inserting the infusion tube into the liquid inlet, the elastic sealing plug deforms, and the infusion tube can pass through the perforation to communicate with the liquid medicine chamber. When the liquid medicine chamber is not installed on the device body, in the natural state of the elastic sealing plug, the perforation is closed to prevent external substances from entering the liquid medicine chamber.

[0020] In summary, the present application includes the following beneficial technical effects:

[0021] 1. The present application can detect the opening and closing state of the air outlet one-way valve through a sensor, thereby judging the user's breathing frequency and sending this information to the central controller. The central controller controls the opening and closing of the atomizing element according to the user's breathing frequency. That is, when the user exhales, the atomizing element is closed, and when the user inhales, the atomizing element is opened, so as to reduce the discharge of atomized liquid medicine through the air outlet channel, thereby reducing the waste of liquid medicine;

[0022] 2. By arranging a spiral blade in the air outlet channel in the present application, when exhaling, the gas can be directly discharged, while the liquid medicine is blocked by the spiral blade and intercepted, and slides down along the spiral blade to be collected in the liquid storage tank, thereby further reducing the waste of liquid medicine.

[0031] The following further elaborates on this application in conjunction with the attached Figures 1-6 drawings.

[0032] This application discloses an atomizer for an atomizing mask.

[0033] Embodiment 1;

[0034] Referring to Figure 1 and Figure 2 , an atomizer for an atomizing mask, this atomizer is installed on the mask. The atomizer includes a body 1, the body 1 is in a V shape, the body 1 is provided with an atomization module and an exhalation module, both the atomization module and the exhalation module are arranged on the inner side surface of the body 1, the body 1 is provided with an intake channel 2 beside the atomization module, the atomization module includes a liquid medicine chamber 3 and an atomization element 4 for atomizing and spraying the liquid medicine in the liquid medicine chamber 3, the body 1 is provided with a fixed channel 5, the atomization element 4 is fixed in the fixed channel 5, the liquid medicine chamber 3 and the atomization element 4 are located on the same side of the body 1, the liquid medicine chamber 3 is detachably connected to the body 1, the liquid medicine chamber 3 includes a chamber body 6 and a connecting pipe 7 arranged on the chamber body 6, the connecting pipe 7 communicates with the chamber body 6, the connecting pipe 7 is internally provided with a liquid guiding strip 8, one end of the liquid guiding strip 8 is located in the liquid medicine chamber 3, and the other end of the liquid guiding strip 8 is used to contact the vibrating piece of the atomization element 4.

[0035] The body 1 is provided with a rear cover 9, the rear cover 9 is detachably connected to the body 1. In this embodiment, the rear cover 9 is fixedly connected to the body 1 through a buckle structure, and an installation cavity 10 is formed between the rear cover 9 and the body 1; when the chamber body 6 is fixed in the installation cavity 10, the liquid guiding strip 8 abuts against the vibrating piece of the atomization element 4.

[0036] The exhalation module includes an exhaust channel 12 and an exhaust check valve 11 arranged on the body 1, the exhaust check valve 11 is arranged in the exhaust channel 12 and is used to limit the entry of external gas into the mask through the exhaust channel 12, and the exhaust check valve 11 uses the user's breathing to open and close the exhaust channel 12. In this application, the exhaust check valve 11 adopts a diaphragm type breathing valve (the structure of the diaphragm type breathing valve is common knowledge and will not be elaborated in this application).

[0037] On one side of the air outlet check valve 11 in the air outlet channel 12, there is a sensor for detecting the opening and closing state of the air outlet check valve 11. The sensor obtains the opening and closing state of the air outlet check valve 11 and sends the opening and closing state to the central controller. The central controller controls the opening and closing of the atomizing element 4 according to the opening and closing state (not shown in the figure).

[0038] When the user exhales, the air outlet check valve 11 will be in an open state due to the increased pressure inside the mask. When the patient inhales, the air outlet check valve 11 will be in a closed state due to the decreased pressure inside the mask. The sensor collects the opening and closing state of the air outlet check valve 11 and sends the opening and closing state to the central controller. The central controller controls the opening and closing of the atomizing element 4 according to the opening and closing state. Specifically, when the air outlet check valve 11 is in an open state, the atomizing element 4 is controlled to close. When the air outlet check valve 11 is in a closed state, the atomizing element 4 is controlled to open. It should be noted that in this embodiment, since exhalation and inhalation are a continuous process, the pressure change inside the mask is a gradual change whether during exhalation or inhalation. Therefore, at the beginning of exhalation, the air outlet check valve 11 is still in a closed state, and the atomizing element 4 is still in an open state, which will cause waste of the atomizing medicine. To reduce this waste, the breathing frequency of the user can be obtained, and an early trigger can be set according to the breathing frequency, so that when the user exhales, the atomizing element 4 is immediately closed, and when the user inhales, the atomizing element 4 is immediately opened.

[0039] The implementation principle of Embodiment 1 of the atomizer for an atomizing mask disclosed in this application is as follows: When the user exhales, the air outlet check valve 11 is opened under the action of the air pressure inside the mask, and the gas exhaled by the user is discharged through the air outlet channel 12. During this process, the sensor senses that the air outlet check valve 11 is opened, and then transmits this signal to the central controller. The central controller closes the atomizing element 4 according to this signal. After exhalation is completed, the air outlet check valve 11 resets and closes the air outlet channel 12. The sensor senses that the air outlet check valve 11 resets and transmits this signal to the central controller. The central controller opens the atomizing element 4 according to this signal. At this time, the atomizing element 4 atomizes the liquid medicine in the liquid medicine chamber 3, and the atomized liquid medicine is inhaled by the user in cooperation with the gas entering through the air inlet channel 2.

[0040] Embodiment 2;

[0041] Refer to Figure 3 and Figure 4 This embodiment is different from Embodiment 1 in that an air inlet check valve 13 for restricting the gas in the mask from entering the mask through the air inlet channel 2 is provided in the air inlet channel 2.

[0042] The air outlet channel 12 is inclined in the thickness direction of the device body 1, and the height of the air outlet channel 12 gradually decreases from the inner side to the outer side of the device body 1; a spiral blade 14 is fixedly connected along the length direction of the air outlet channel 12 inside the air outlet channel 12 outside the air outlet one-way valve 11; a liquid storage tank 15 is provided on the lower side of the lower end of the air outlet channel 12 of the device body 1, and the liquid storage tank 15 and one end of the air outlet channel 12 close to the outer side of the device body 1 are communicated through a hose 23.

[0043] Referring to Figure 5 and Figure 6 , a micro piezoelectric pump 16 is installed inside the device body 1. The liquid inlet 18 of the micro piezoelectric pump 16 is communicated with the lower end of the liquid storage tank 15. The liquid outlet of the micro piezoelectric pump 16 is communicated with and fixedly connected to an infusion tube 17. A liquid inlet 18 is opened at the upper end of the bin body 6. A valve assembly is provided in the liquid inlet 18. When the liquid medicine bin 3 is installed on the device body 1, the end of the infusion tube 17 away from the micro piezoelectric pump 16 is used to insert into the liquid inlet 18 and open the valve assembly to communicate with the liquid medicine bin 3.

[0044] In this embodiment, when the connecting tube is docked with the vibrating piece of the atomizing element 4, the infusion tube 17 can be inserted into the liquid inlet 18.

[0045] The valve assembly includes an elastic sealing plug 19. The elastic sealing plug 19 is fixedly arranged in the liquid inlet 18 and used to seal the liquid inlet 18. A perforation 20 for inserting the infusion tube 17 is opened on the elastic sealing plug 19. When the elastic sealing plug 19 is not deformed, the perforation 20 is closed.

[0046] In this embodiment, a guiding groove 21 is opened on the surface of the elastic sealing plug 19 facing the infusion tube 17, and the infusion tube 17 penetrates into the perforation 20 through the guiding groove 21.

[0047] Furthermore, a liquid level sensor can be set in the liquid storage tank 15, and a liquid level threshold is set. When the liquid level in the liquid storage tank 15 reaches the threshold, the processor obtains this signal and controls the micro piezoelectric pump 16 to start, pumping the liquid medicine in the liquid storage tank 15 to the bin body 6.

[0048] Referring to Figure 4 , it should be noted that an air cavity 22 is provided inside the device body 1. The air inlet channel 2 and the air outlet channel 12 are both communicated with the air cavity 22. An air hole 24 communicated with the air cavity 22 is opened on the outer wall of the device body 1 to ensure that gas can enter and exit normally.

[0049] The implementation principle of the atomizer of the atomizing mask disclosed in this application in Embodiment 2 is as follows: when the user exhales, part of the atomized liquid medicine remaining inside the mask enters the air outlet channel 12 through the exhaled gas. The gas can be directly discharged, while the liquid medicine is blocked by the spiral blade 14 and intercepted, and slides down along the spiral blade 14 to the liquid storage tank 15 for collection. When the liquid level in the liquid storage tank 15 reaches a certain value, the micro piezoelectric pump 16 pumps the liquid medicine in the liquid storage tank 15 to the bin body 6.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
