Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a nebulizer, a nebulizer control method, and a storage medium. Background Art

[0002] With the rapid development of social economy, the problem of air quality has become increasingly prominent, resulting in the incidence of respiratory diseases (chronic bronchitis, chronic pharyngitis, asthma, etc.) rising continuously in recent years. As an effective means of treating respiratory diseases, nebulizer therapy uses a nebulizer to directly deliver drugs to the diseased area. It is favored by the majority of patients due to its advantages such as quick effect, good therapeutic effect, small dosage and no side effects.

[0003] Nebulizers are mainly divided into three categories: ultrasonic nebulizers, compression nebulizers, and mesh nebulizers. Currently, the most popular and effective one is the mesh nebulizer (handheld nebulizer). The treatment process mainly uses piezoelectric ceramics to atomize the liquid medicine into tiny particles, which are then inhaled into the respiratory tract and lungs for deposition, thus achieving painless, rapid and effective treatment. However, due to the existence of some defects, its further development is also limited. For this reason, experts and scholars have invested in the research of this technology and have achieved certain results. Kang Jie and others from Nanjing Yuyue Co., Ltd. disclosed an invention patent with patent number "CN107412926 A", which solves the problem of vibration suppression of microporous sheets by means of electrical connection and fixing structure of the microporous sheets of a microporous atomization device; Kou Jingang from Jiujian Medical Instrument Co., Ltd. disclosed a patent with patent number "CN 209253850 U", which solves the problem of cold air accumulation in the patient's lungs or reduced comfort during use due to the low temperature of the atomized liquid through a built-in heating device; Zhong Liangzhou from Shenzhen Daohe Medical Equipment Co., Ltd. disclosed a patent with patent number "CN 210542739 U", which realizes the free disassembly and replacement of the atomizer sheet by arranging easily detachable connectors and electrodes at the nozzle.

[0004] The research on the above technologies has greatly promoted the technological development of the mesh nebulizer industry, making the patient experience more comfortable and the treatment effect better; however, for the mesh nebulizer, the nebulizer sheet is a consumable and is prone to clogging and damage, and needs to be replaced in time. In order to ensure the sealing of the nebulizer sheet during use, the replacement process is complicated, which reduces the user experience, and the simple structure has poor sealing.

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] The existing atomizer has the problem that the atomizer sheet is inconvenient to replace and cannot be replaced in time. The present invention adsorbs the magnetic structure 5 on the nozzle 4 through the magnetic field generated by the magnetic mechanism 2, so that the magnetic structure 5 is fixed in the plug-in hole, and the coil current on the magnetic mechanism 2 is adjusted to change the force between the magnetic structure 5 and the plug-in hole, thereby improving the pressure between the nozzle 4 and the sealing ring 6, so that the user has a higher sealing performance when using it, and when the power is off, the electromagnetic coil on the magnetic mechanism 2 is powered off, so that the user can easily remove the nozzle without using screws to disassemble it, thereby improving the convenience of replacing the atomizer sheet. At the same time, the present invention provides an atomizer control method, which uses the conduction current of the atomizer sheet to determine whether the atomizer sheet is blocked, and controls whether the electromagnetic coil on the magnetic mechanism 2 needs to be powered off for replacement, thereby avoiding the problem of users blindly replacing the atomizer sheet.

[0031] To further illustrate the technical solution of the present invention, Figure 1-Figure 5 , the following specific embodiments are provided.

[0032] Example 1

[0033] In this embodiment, a nebulizer is provided, such as Figure 1-Figure 3 As shown, it includes: a cup body 1, which is used to hold liquid and has a liquid outlet 11 on its side wall; a magnetic mechanism 2, which is fixedly arranged on the side wall of the cup body 1; an atomizer sheet 3, which is arranged at the position of the liquid outlet 11 of the cup body 1; a nozzle 4, on which is a mounting portion 41, on which is a magnetic conductive structure 5, and the mounting portion 41 fixes the atomizer sheet 3 at the position of the liquid outlet 11 through the magnetic attraction between the magnetic conductive structure 5 and the magnetic mechanism 2; when the magnetic mechanism 2 is energized, the magnetic mechanism 2 generates a magnetic attraction on the magnetic conductive structure, so that the mounting portion 41 is pressed against the cup body 1 to form a sealed connection; when the magnetic mechanism 2 loses power, the magnetic attraction force generated by the magnetic mechanism 2 on the magnetic conductive structure 5 is reduced, so that the force between the mounting portion 41 and the cup body 1 is reduced, and the nozzle 4 can be removed from the cup body 1; the magnetic mechanism 2 can be controlled by the power-on current to adjust the magnetic attraction force on the magnetic conductive structure 5 and thereby change the force of the mounting portion 41 on the cup body 1.

[0034] The opening above the cup body 1 is provided with a cup cover 20, which is sealed and connected to the cup body 1 through a sealing ring 21. The accommodating space inside the cup body 1 is communicated with the liquid outlet 11, so that the liquid medicine can be sprayed out through the nozzle 4.

[0035] The mounting portion 41 forms a sealed connection with the cup body 1 through the sealing ring 6. The pre-tightening force on both sides of the sealing ring 6 can be increased by adjusting the magnetic force of the magnetic mechanism, thereby improving the sealing performance.

[0036] In one embodiment, the magnetic mechanism 2 includes a magnetizer 21 and a coil 22, the magnetizer 21 is provided with a plug-in hole 21a, the outer surface of the magnetizer 21 is provided with a coil 22, the coil 22 is arranged around the plug-in hole 21a, and the magnetic structure 5 is inserted into the plug-in hole 21a and matched with the plug-in hole 21a. When the atomizer is not in operation, the coil 22 is not energized, and the magnetic structure 5 is adsorbed by the magnetizer 21 to fix the nozzle 4 at the liquid outlet 11 of the cup body 1. At this time, the magnetic force is not large, and the user can manually disassemble the nozzle 4 to replace the atomizer sheet 3. When the user uses it, the atomizer 3 is in operation, and the direction of the magnetic field generated by the coil 22 being energized is the same as the direction of the magnetizer 21, which enhances the suction force of the magnetizer 21, thereby increasing the sealing of the nozzle 4 and the atomizer sheet 3 to prevent leakage of the liquid medicine. Preferably, the magnetic structure 5 can be a magnetic column, which is inserted into the plug-in hole 21a.

[0037] In this embodiment, the number of magnetic mechanisms 2 can be more than two and distributed around the liquid outlet 11, or can be set on the side wall of the cup body 1. The number of magnetic mechanisms 2 can also be one, and the magnetic conductive structure 5 can be made into a cylindrical shape, surrounding the liquid inlet, and the magnetic conductive body 21 is also cylindrical, with a coil wound on its outer surface, and the two are plugged together and form a sealed connection through magnetic force. In this embodiment, it is preferred that there are two magnetic mechanisms 2, which are set around the liquid outlet 11.

[0038] Furthermore, a magnetic cap 51 is provided on the magnetic structure 5, and the magnetic cap 51 is fixed on the nozzle 4. The magnetic cap 51 can be embedded in the mounting portion of the nozzle 4; when the magnetic structure 5 is inserted into the plug hole, the magnetic cap 51 is arranged opposite to the plug hole. The provision of the magnetic cap 51 not only facilitates the fixation of the magnetic structure 5, but also increases the axial adsorption force of the magnetic structure 5 to improve the sealing performance.

[0039] The magnetizer 21 and the magnetic structure 5 are made of magnetic materials. The relative magnetic poles of the magnetizer 21 and the magnetic structure 5 are opposite, so that the two can attract each other to fix the nozzle at the position of the liquid inlet, thereby increasing the attraction to the magnetic structure 5.

[0040] like Figure 4As shown, the atomizer sheet is provided with two electrodes and a detection circuit connecting the two ends of the two electrodes, the detection circuit includes a coil 22, a power supply 8, a first switch 7, a controller 9 and a current detection module 10, the power supply 8, the first switch 7, the power port of the controller 9, the coil 22, the current detection module 10 and the two electrodes form a series connection relationship in the detection circuit, and the signal output port of the current detection module 10 is electrically connected to the first signal input port of the controller 9, and the signal output port of the controller 9 is electrically connected to the control port of the first switch 7. The conduction current of the atomizer sheet 3 can be detected, and whether the atomizer sheet is blocked can be judged according to the magnitude of the conduction current, so as to prompt the user to replace the atomizer sheet.

[0041] The atomizer is mainly composed of piezoelectric ceramics and stainless steel sheets. During the operation of the atomizer, after the atomizer is energized, the piezoelectric ceramics vibrate at a certain frequency according to the inverse piezoelectric effect, driving the liquid in the medicine cup to spray out through the horn hole on the stainless steel sheet of the atomizer. When blocked, the atomizer does not spray, the load decreases, and the voltage remains unchanged, causing the current at the atomizer to suddenly increase. Therefore, the degree of blockage of the atomizer can be judged according to the size of the conduction current of the atomizer.

[0042] like Figure 4 As shown, the atomizer also includes a detection electrode 23 arranged at the liquid outlet 11, and the detection electrode 23 is connected in parallel with the first switch 7, the atomizer sheet 3 and the current detection module 10 to form two branch circuits, wherein the first switch 7, the atomizer sheet 3 and the current detection module 10 are connected in series to form a first branch, the detection electrode 23 forms a second branch, the power supply 8, the controller 9 and the coil 22 are connected in series to form a main circuit, and the first branch and the second branch are connected in parallel and then connected in series at both ends of the main circuit.

[0043] The atomizer also includes a detection electrode 23 disposed at the liquid outlet 11. The detection electrode 23 is connected in parallel with the first switch 7, the atomizer sheet 3 and the current detection module 10 to form two branch circuits. The two branch circuits are connected in series with the main circuit. The controller 9 and the coil 22 are disposed on the main circuit of the two branch circuits. The direction of the magnetic field generated by the coil 22 being energized is the same as the direction of the magnetic field of the magnetic conductor 21. By setting the detection electrode 23, the liquid level of the atomizer 3 and the mineral content of the liquid can be detected. When the liquid level is too low or the mineral content of the liquid is low, it is judged that there is less liquid medicine in the cup body 1, there is no liquid medicine or it is not liquid medicine, so as to avoid the atomizer sheet 3 from being damaged due to no-load operation.

[0044] Further optionally, the atomizer further includes a second switch 24 , which is disposed on the main circuit and is connected in series with the controller 9 and the coil 22 .

[0045] In this embodiment, the controller 9 may be a microprocessor.

[0046] In this embodiment, the sealing and disassembly of the nozzle mounting portion 41 and the cup body 1 are achieved by controlling whether the coil is energized, which solves the problem of poor sealing during use of a simple structure and the problem of complex disassembly and replacement of a complex structure. After the user finishes using the atomizer, the second switch coil is turned off to cut off the power, and the user can disassemble the nozzle to clean and replace the atomizer sheet.

[0047] Example 2

[0048] This embodiment takes Embodiment 1 as an example to provide an embodiment of a control method for an atomizer. Figure 5 As shown, the control method includes: when the first switch is closed, real-time monitoring of the conduction current of the atomizer sheet is performed, and judging whether it is necessary to prompt to replace the atomizer sheet according to the conduction current.

[0049] Further optionally, judging whether it is necessary to prompt the user to replace the atomizer sheet based on the conduction current includes: if the conduction current is greater than or equal to a preset current, the power supply is controlled to be disconnected and the coil is de-energized after the user is prompted to replace the atomizer sheet; if the conduction current is less than the preset current and greater than zero, the atomizer is controlled to operate normally according to a preset atomization rate; after the user finishes use, the second switch is manually disconnected and the conduction current is equal to zero.

[0050] In this embodiment, different colored indicator lights can be used to remind the user whether to replace the atomizer sheet. For example, the indicator light can be red to indicate that the atomizer sheet needs to be replaced, green to indicate that the atomizer is operating normally, and yellow to indicate that the atomizer equipment is faulty. Other reminders such as voice prompts can also be used.

[0051] Further optionally, the control method also includes: after the user closes the second switch and before the first switch is closed, determining whether the atomizer sheet is in a no-load operating environment; if the atomizer sheet is not in a no-load operating environment, the controller controls the first switch to close.

[0052] Further optionally, judging whether the atomizer sheet is in a no-load operation environment includes: if the detection electrode detects a current signal, it is judged that it is not in a no-load operation environment, and the controller controls the first switch to close; if the detection electrode does not detect a current signal, it is judged that it is in a no-load operation environment, and the first switch is in an open state. In this embodiment, the atomizer first determines whether the atomizer sheet is in a no-load state by judging the conductivity of the liquid in the cup body through the detection electrode before operation, so as to prevent the atomizer sheet from being burned by no-load operation and air vibration.

[0053] The control steps adopted in this embodiment may be:

[0054] S10, when the user uses it, the second switch is turned on, the coil is energized, and the sealing between the nozzle and the cup body is enhanced;

[0055] S20, if the detection electrode 23 detects a current signal, then execute step S30;

[0056] S30, judgment I 监测 and I 预设 Satisfied: I 监测 ≥I 预设 , where I 监测 is the current detected by the detection electrode, I 预设 represents a preset current; if satisfied, execute step S40; if not satisfied, execute step S50;

[0057] S40, reminding the user to replace the atomizer sheet and controlling the power supply to be turned off;

[0058] S50, controlling the first switch to turn on, so that the atomizing sheet is powered on, and controlling the atomizer to work according to a preset atomization rate;

[0059] S60: After the user finishes using the device and turns off the second switch, the coil loses power; the nozzle can be removed for replacement or cleaning.

[0060] This embodiment determines the blockage condition of the atomizer sheet by monitoring the conduction current of the atomizer sheet. When the atomizer sheet is seriously blocked, the power supply is automatically disconnected, so that the electromagnetic coil is automatically powered off. The adsorption force of the magnetic conductive structure is low, and the user only needs to pull out the nozzle to replace the atomizer sheet, thereby avoiding the user's replacement of the atomizer sheet too early to increase the user's usage cost. If the atomizer sheet is replaced too late, bacteria will grow and affect the user's health, thereby improving the user's usage experience.

[0061] The exemplary embodiments of the present disclosure are specifically shown and described above. It should be understood that the present disclosure is not limited to the detailed structures, configurations or implementations described herein; on the contrary, the present disclosure is intended to cover various modifications and equivalent configurations included in the spirit and scope of the appended claims.
