Description

Technical Field

[0001] The present invention belongs to the field of atomization utilization, and particularly relates to a medical atomizer and a control method thereof. Background Art

[0002] Inhalation therapy is an important and effective treatment method in the treatment of respiratory diseases, such as in the treatment of diseases like cold, fever, cough, asthma, etc. An atomizer is used to atomize the liquid medicine into tiny particles, and the user inhales the medicine into the respiratory tract and lungs through breathing and deposits it, and it is absorbed through its mucous membrane, so as to achieve the purpose of painless, rapid and effective treatment.

[0003] At present, this field has developed from relatively large compressed atomizers to portable mesh atomizers using the principle of ceramic piezoelectric vibration. The atomization sheet of the mesh atomizer is made of a metal mesh sheet and ceramic material. Under the drive of a certain frequency oscillation of the circuit, the ceramic vibration sheet performs resonant oscillation, thereby driving the metal mesh sheet to oscillate at high speed, enabling the liquid medicine to pass through numerous tiny mesh holes on the metal mesh sheet and be quickly ejected, forming countless tiny atomized particles and atomizing at normal temperature.

[0004] Generally, a mesh atomizer includes two parts: an atomizer main body and an atomizing cup. One side of the atomizing cup is provided with a mist outlet, the mist outlet is communicated with the atomization cavity in the atomizing cup, and an atomization sheet is provided at the bottom of the mist outlet. The atomization sheet atomizes the medicine in the atomization cavity and discharges it from the mist outlet for the patient to inhale. And electronic devices such as a power supply and a control circuit board are provided in the atomizer main body. The power supply is used to supply power to the entire medical atomizer, and the control circuit board controls the operation of the atomization sheet. When in use, first pour the medicine into the atomizing cup, cover the cup lid, then start the atomization sheet, put the mist outlet into the mouth, and completely cover it with the lips to inhale the atomized medicine.

[0005] Moreover, when in use, the atomization sheet of the medical atomizer needs to be placed vertically or at a very small inclination angle to ensure that the liquid medicine in the atomization cavity can contact the atomization sheet and enable the normal operation of the atomization cavity.

[0006] However, after the medical atomizer is made portable and miniaturized, the atomizer main body needs to be held by hand, and the mist outlet is integrally formed on the atomizing cup. Therefore, during the holding process, it is inevitable that the inclination angle of the atomizer main body is too large, which may cause the atomization sheet to separate from the liquid medicine, resulting in the inability of the atomization sheet to operate normally. In particular, for some special patients who use the atomizer in a side-lying or looking-down position, due to the separation of the atomization sheet from the liquid medicine caused by the inclination, the portable medical atomizer is difficult to meet their needs. Summary of the Invention

[0007] The present invention provides a medical atomizer and a control method thereof to solve the technical problem mentioned in the background art that the liquid medicine separates from the atomization sheet due to the inclination angle.

[0008] To achieve the above object, the specific technical solutions of the medical nebulizer and its control method of the present invention are as follows:

[0009] The present invention discloses a medical nebulizer, which includes a nebulization cup. A nebulization chamber and a nebulization sheet are provided inside the nebulization cup. A movable partition is provided on the bottom surface of the nebulization chamber. The partition moves towards the side close to the nebulization sheet to level the low-lying area formed by the inclination of the bottom surface of the nebulization chamber, and guides the liquid medicine accumulated in the low-lying area during inclination to the nebulization sheet, so that the liquid medicine contacts the nebulization sheet.

[0010] Further, one end of the partition close to the nebulization sheet is rotatably connected to the bottom surface of the nebulization chamber, and the end of the partition far from the nebulization sheet is connected to the inner wall of the nebulization chamber and can move towards the side close to the nebulization sheet.

[0011] Further, an expansion surface and a diversion surface are formed on the bottom surface of the nebulization chamber. The expansion surface is horizontally arranged and located on the side far from the nebulization sheet, while the diversion surface is inclined relative to the expansion surface. The diversion surface gradually slopes downward as it approaches the nebulization sheet to guide the liquid medicine to the nebulization sheet.

[0012] Further, one end of the partition is rotatably connected at the junction of the expansion surface and the diversion surface.

[0013] Further, the partition is slidably connected to the bottom surface of the nebulization chamber. The partition is located on the side of the nebulization chamber far from the nebulization sheet and can move towards the side close to the nebulization sheet.

[0014] Further, an expansion surface and a diversion surface are formed on the bottom surface of the nebulization chamber. The expansion surface is horizontally arranged and located on the side far from the nebulization sheet, while the diversion surface is inclined relative to the expansion surface. The diversion surface gradually slopes downward as it approaches the nebulization sheet to guide the liquid medicine to the nebulization sheet.

[0015] Further, one end of the partition is slidably connected to the expansion surface.

[0016] The present invention also discloses a control method for a medical nebulizer, including:

[0017] Obtaining the placement state of the nebulization cup;

[0018] When the nebulization cup is tilted, move the partition to guide the liquid medicine onto the nebulization sheet;

[0019] When the nebulization cup is vertical, keep the partition in its initial position.

[0020] Further, obtaining the placement state of the nebulization cup includes:

[0021] Obtaining the tilt angle of the nebulization cup through an attitude sensor.

[0022] Further, obtaining the placement state of the nebulization cup includes:

[0023] Obtain whether there is water in the liquid level sensor near the atomizing sheet side and the auxiliary liquid level sensor far from the atomizing sheet side.

[0024] The medical atomizer and its control method of the present invention have the following advantages:

[0025] 1. By arranging a movable partition in the atomizing cup, when the atomizer is tilted, rotate the partition to make the liquid medicine in the atomizing cup flow into the mist outlet, so that the atomizer can produce mist normally;

[0026] 2. Through the attitude sensor, it is used to collect the attitude of the atomizer, so as to control the movement of the partition, and it can be used for normal atomization when the atomizer is tilted;

[0027] 3. By setting the liquid level sensor, obtain the accumulation state of the liquid level, so as to control the movement of the partition, and it can be used for normal atomization when the atomizer is tilted. Brief Description of the Drawings

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0037] Those skilled in the art can understand that although some embodiments herein include certain features included in other embodiments rather than other features, the combination of the features of different embodiments means that it is within the scope of the present invention and forms different embodiments. For example, in the claims, any one of the claimed embodiments can be used in any combination.

[0038] As Figure 1 shown, the medical atomizer of the present invention includes an atomizer main body 1 and an atomizing cup 2. The atomizing cup 2 is formed with an atomizing chamber 21 and an atomizing port 22, and the atomizing chamber 21 and the atomizing port 22 are in communication. An atomizing sheet 23 is provided in the atomizing port 22, so as to atomize the liquid medicine in the atomizing chamber 21 and discharge the atomized liquid medicine from the atomizing port 22. Among them, the atomizing port 22 protrudes from one side of the atomizing cup 2 for a patient to put the mouth to cover the atomizing port 22. The atomizing sheet 23 is vertically arranged in the atomizing port 22 to ensure that the atomizing sheet 23 contacts the liquid medicine in the atomizing chamber 21. A power supply and a control circuit board are provided in the atomizing cup 2. The power supply supplies power to the entire medical atomizer, and the control circuit board controls the operation of the atomizing sheet 23.

[0039] For the convenience of recycling the nebulizer main body 1 and the nebulizer cup 2, it is necessary to facilitate the replacement of both. An installation platform is formed on the lower side of the nebulizer cup 2, and the installation platform is detachably connected to the nebulizer main body 1, so as to facilitate the installation of the nebulizer cup 2 on the nebulizer main body 1. Since the nebulizer main body 1 and the nebulizer cup 2 are detachably connected, when the life of one of them is exhausted, the two are separated and corresponding replacements are made to extend the life of the medical nebulizer and facilitate installation and fixation.

[0040] Specifically, the installation platform is provided with a surrounding buckle, the nebulizer main body 1 is provided with a groove, and a bayonet is provided on the inner wall of the groove. The installation platform of the nebulizer cup 2 contacts the nebulizer main body 1, so that the buckle is inserted into the groove of the nebulizer main body 1 and is engaged with the bayonet, thereby installing the nebulizer cup 2 on the nebulizer main body 1. In addition to using snap connection, detachable connection methods such as rotary snap connection can also be used to fix the nebulizer cup 2.

[0041] A cup cover 4 is provided on the nebulizer cup 2, and the cup cover 4 seals the atomization chamber 21. Thus, by opening the cup cover 4, the liquid medicine is introduced into the atomization chamber 21 to supplement the liquid medicine in the atomization chamber 21 for multi-course treatment.

[0042] An expansion surface 211 and a diversion surface 212 are formed on the bottom surface of the atomization chamber 21. The expansion surface 211 is horizontally arranged and located on the side away from the atomization sheet 23, while the diversion surface 212 is inclined relative to the expansion surface 211. The diversion surface 212 gradually slopes downward as it approaches the atomization sheet 23 to guide the liquid medicine to the atomization sheet 23 and ensure that the liquid medicine contacts the atomization sheet 23.

[0043] Among them, the expansion surface 211 is located inside the installation platform, so that the inner and outer walls of the nebulizer cup 2 are parallel, which is convenient for the molding of the nebulizer cup 2. Moreover, if only a diversion inclined surface is provided on the bottom surface of the atomization chamber 21, the volume of the atomization chamber 21 will be reduced, which is not conducive to filling more liquid medicine in the smaller nebulizer cup 2.

[0044] However, when the nebulizer cup 2 is tilted to raise the atomization port 22, some liquid medicine will accumulate in the low-lying corner on the side of the expansion surface 211 away from the diversion surface 212. Therefore, a movable partition 3 is provided in the nebulizer cup 2, and the partition 3 moves toward the side close to the atomization sheet 23, so as to guide the liquid medicine to the atomization sheet 23, make the liquid medicine contact the atomization sheet 23, and prevent the liquid medicine from remaining on the expansion surface 211.

[0045] Specifically, the partition 3 can move in two ways:

[0046] In one embodiment, one end of the partition plate 3 is rotatably connected to the junction of the expansion surface 211 and the diversion surface 212, and the other end of the partition plate 3 is connected to the inner wall of the atomization chamber 21. Thus, the partition plate 3 rotates towards the side close to the atomization sheet 23 to guide the liquid medicine onto the atomization sheet 23. In the initial state of the partition plate 3, the partition plate 3 fits against the expansion surface 211, thereby reducing the influence of the partition plate 3 on the atomization chamber 21. When the medical atomization chamber 21 is tilted to cause the atomization port 22 to lift, the partition plate 3 rotates by no less than the tilt angle of the medical atomization chamber 21, thereby smoothing the depression formed at the expansion surface 211 and ensuring the guidance of the liquid medicine by the bottom surface of the atomization chamber 21.

[0047] In another embodiment, one end of the partition plate 3 is slidably connected to the expansion surface 211, and the other end of the partition plate 3 is connected to the inner wall of the atomization chamber 21. Thus, the partition plate 3 translates towards the side close to the atomization sheet 23 to guide the liquid medicine onto the atomization sheet 23. In the initial state of the partition plate 3, the partition plate 3 fits against the side of the inner wall of the atomization chamber 21 away from the atomization sheet 23, thereby reducing the influence of the partition plate 3 on the atomization chamber 21. When the medical atomization chamber 21 is tilted to cause the atomization port 22 to lift, the partition plate 3 gradually moves to the junction of the expansion surface 211 and the diversion surface 212, thereby smoothing the depression formed at the expansion surface 211 and ensuring the guidance of the liquid medicine by the bottom surface of the atomization chamber 21.

[0048] Of course, the partition plate 3 can also be arranged on the bottom surface of the atomization chamber 21 with other shapes, such as when the atomization chamber 21 is provided with only a flat surface or an inclined surface. When adopting the rotation method, it is only necessary to ensure that one end of the partition plate 3 close to the atomization sheet 23 is rotatably connected to the bottom surface of the atomization chamber 21, and the other end of the partition plate 3 away from the atomization sheet 23 is connected to the inner wall of the atomization chamber 21 and can move towards the side close to the atomization sheet 23. When adopting the movement method, it is only necessary to ensure that the partition plate 3 is located on the side of the atomization chamber 21 away from the atomization sheet 23 and can move towards the side close to the atomization sheet 23. Thus, through the movement of the partition plate 3, the depression formed at the expansion surface 211 during tilting is smoothed, ensuring the contact between the liquid medicine and the atomization sheet 23.

[0049] To drive the movement of the partition plate 3, a motor or a linear push rod can be arranged in the atomization chamber 21. The partition plate 3 is directly installed on the output shaft of the motor, and the partition plate 3 is driven to rotate accordingly. And the partition plate 3 is fixed on the telescopic rod of the linear push rod, thereby driving the partition plate 3 to translate.

[0050] To facilitate the control circuit board to control the partition plate 3, it is necessary to set sensors to monitor the state of the atomization cup 2.

[0051] Specifically, an attitude sensor 5 is installed on the atomizer main body 1. The attitude sensor 5 is electrically connected to the control circuit board, and the control circuit board is electrically connected to the driver for driving the movement of the partition plate 3. Thus, the attitude sensor 5 obtains the tilt angle of the atomization cup 2 to move the partition plate 3 and guide the liquid medicine onto the atomization sheet 23.

[0052] A liquid level sensor is provided on the diversion surface 212, generally a water detection needle 6. The water detection needle 6 is fixed on the installation platform, and the end of the water detection needle 6 extends to the diversion surface 212 to detect the liquid level at the atomizing sheet 23. The liquid level sensor is electrically connected to the control circuit board, thereby preventing the atomizing sheet 23 from dry burning.

[0053] As Figure 3 shown, when the atomizer is operating, first check if there is water in the atomizing cup 2. If there is no water, start the water shortage prompt and shut down the machine. When water is detected, the atomizer atomizes normally and activates the attitude sensor 5. The attitude sensor 5 in the atomizer body 1 is used to detect the attitude angle of the atomizer. During the use of the atomizer, it is inevitable that the angle will tilt. When tilted to a certain angle, the liquid medicine in the atomizing cup 2 will flow into the low-lying area away from the atomizing sheet 23. The attitude sensor 5 collects the tilt angle α of the atomizer with respect to the vertical axis at this time. At this time, the motor is started to work, and the tilt angle of the partition plate 3 is adjusted to α, so that the liquid flows smoothly to the mist outlet end of the atomizing sheet 23, ensuring normal atomization of the atomizer. When the user uses the atomizer lying down or reclining, the mist can still be discharged smoothly.

[0054] In addition to the attitude sensor 5, a water detection capacitor 11 as an auxiliary liquid level sensor can also be provided in the low-lying area. When the atomizer is working, if it tilts, the liquid medicine in the atomizing cup 2 will flow into the low-lying area away from the atomizing sheet 23. At this time, the water detection needle 6 will detect no water, while the water detection capacitor in the bottom plate of the atomizing cup 2 will detect water. Then move the partition plate 3 to make the water remaining on the other side of the atomizing sheet 23 flow into the atomizing sheet 23 to make it atomize normally.

[0055] Figure 4 Schematically shows a flowchart of a medical atomizer control method according to an embodiment of the present invention. Referring to Figure 4 , the injection molding machine control method proposed in the embodiment of the present invention specifically includes steps S11 to S13, as follows:

[0056] S11. Obtain the placement state of the atomizing cup 2;

[0057] S12. When the atomizing cup 2 is tilted, move the partition plate 3 to guide the liquid medicine onto the atomizing sheet 23;

[0058] S13. When the atomizing cup 2 is vertical, keep the partition plate 3 in the initial position.

[0059] In an embodiment of the present invention, obtaining the placement state of the atomizing cup 2 includes: directly obtaining the tilt angle of the atomizing cup 2 through the attitude sensor 5.

[0060] In another embodiment of the present invention, obtaining the placement state of the atomizing cup 2 includes: obtaining whether there is water in the liquid level sensor on the side close to the atomizing sheet 23 and the auxiliary liquid level sensor on the side away from the atomizing sheet 23.

[0061] If the liquid level sensor detects the presence of water, there is no need to move the partition 3;

[0062] If the liquid level sensor detects a lack of water while the auxiliary liquid level sensor detects the presence of water, move the partition 3;

[0063] If the liquid level sensor detects a lack of water and the auxiliary liquid level sensor also detects a lack of water, an alarm is given to prevent dry burning.

[0065] When the partition 3 is moved in the medical nebulizer and its control method provided by the embodiments of the present invention, the liquid medicine is guided onto the atomizing sheet 23 to ensure the normal operation of the atomizing sheet 23.
