Abstract
Description
Technical Field
[0001] This utility model relates to an atomizing device, and more particularly to an atomizing device with the function of detecting residual trace amounts of medicine. Background Technology
[0002] Existing nebulizers typically incorporate a detection element inside the medication cup to detect the residual dosage of the medication within the cup. However, in the prior art, the detection element is often offset to one side (e.g., the right side) inside the medication cup. This causes the residual medication to concentrate in a position far from the detection element when the cup is tilted (e.g., tilted to the left), making it undetectable. Consequently, the residual dosage is not accurately determined, reducing the precision and reliability of medication use.
[0003] Therefore, how to overcome the above-mentioned defects through structural design improvements has become one of the important issues to be addressed in this field. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a nebulizing device to address the shortcomings of the prior art, which is to solve the technical problem that the detection element inside the existing nebulizing device is often biased to one side inside the medicine cup, resulting in misjudgment of the residual dosage in the medicine cup.
[0005] To address the aforementioned technical problems, one technical solution adopted by this utility model is to provide an atomizing device, comprising a cup body, an atomizing module, and a detection module. The cup body has an opening and a through hole, the opening and through hole being respectively located at the top and bottom of the cup body. The cup body has an internal storage tank for containing liquid medicine, and the storage tank connects to the opening and the through hole. The atomizing module and the detection module are disposed inside the cup body. The atomizing module is located directly above the through hole, and the detection module is located above the atomizing module. The detection module has a detection area, and the vertical projection of the detection area is completely within the range of the vertical projection of the through hole.
[0006] Optionally, the detection module includes a metal component that extends over the through-hole and is partially exposed by being covered by an insulating material, the exposed portion forming the detection area.
[0007] Optionally, the detection module includes a metal component that extends from one side of the inner wall of the cup to above the through hole and is partially exposed while being covered by an insulating material, with the exposed portion forming the detection area.
[0008] Optionally, the liquid storage tank has a first inner wall and a second inner wall, the first inner wall being disposed between the opening and the second inner wall, the second inner wall being disposed between the first inner wall and the through hole, and the inner diameter of the liquid storage tank on the first inner wall gradually decreasing from the opening toward the second inner wall.
[0009] Optionally, a first distance between the detection area and the through hole is less than a second distance between the detection area and the opening.
[0010] Optionally, the atomizing device also includes a cover pivotally connected to one side of the cup body, the cover being used to close the opening.
[0011] Optionally, the vertical projection of the detection area is located at the center of the range of the vertical projection of the through hole.
[0012] Optionally, the atomizing device further includes a main unit and a housing, the housing being used to connect the main unit and the cup body, the housing having an air chamber inside, and the housing including a nozzle for communicating with the air chamber, while the liquid storage tank is communicating with the air chamber through a through hole.
[0013] Optionally, the main unit includes a control module electrically connected to the atomization module and the detection module. When the liquid level of the medicine is higher than the detection area, the detection area contacts the medicine and outputs a detection signal to the control module, which then controls the atomization module to atomize the medicine.
[0014] Optionally, the main unit includes a control module electrically connected to the atomization module and the detection module. When the liquid level is lower than the detection area, the detection area cannot contact the liquid and stops outputting a detection signal to the control module, causing the control module to stop controlling the atomization module to atomize the liquid.
[0015] One of the beneficial effects of this invention is that the atomizing device provided by this invention, through the technical solution that "the vertical projection of the detection area is completely within the range of the vertical projection of the through hole," ensures that the detection area is basically located in the middle of the storage tank, rather than offset to one side. This coaxial alignment of the detection area and the through hole helps improve the sensing accuracy of the detection module in detecting changes in the liquid level within the storage tank, ensuring consistency in the amount of residual medication to be retained, and avoiding misjudgments or signal distortion caused by module misalignment, thereby ensuring the stability and safety of the atomization operation.

These terms are primarily used to distinguish one component from another. Furthermore, the term "or" as used herein should, as appropriate, include any combination of one or more related listed items.
[0026] Example
[0027] See Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram of the atomizing device of this utility model. Figure 2 This is an exploded view of the atomizing device of this utility model. An embodiment of this utility model provides an atomizing device D, which mainly includes: a cup body 1, a main unit 2, a housing 3, an atomizing module 4, and a detection module 5.
[0028] See Figures 2 to 4 , Figure 3 This is a schematic diagram of the cup body of this utility model. Figure 4This is a cross-sectional schematic diagram of the cup body of this utility model. The housing 3 is used to connect the main unit 2 and the cup body 1. The housing 3 has an air chamber 30 inside, and includes a nozzle 31 for communicating with the air chamber 30. The cup body 1 has an opening 10 and a through hole V, respectively located at the top and bottom of the cup body 1. The cup body 1 has a liquid storage tank C inside, used to hold the medicine liquid Q (see...). Figure 4 The liquid storage tank C is connected to the opening 10 and the through hole V, and the liquid storage tank C is interconnected with the air chamber 30 below through the through hole V. Figure 2 As shown, the cup body 1 also includes a cover 11, which is rotatably pivotally connected to one side of the cup body 1 and is used to close the opening 10. It should be noted that, for illustrative purposes, Figure 3 The shell cover 11 is omitted from the illustration.
[0029] like Figure 4 As shown, the liquid storage tank C has a first inner wall C1 and a second inner wall C2 arranged sequentially. The first inner wall C1 is located between the opening 10 and the second inner wall C2, while the second inner wall C2 is located between the first inner wall C1 and the through hole V. The first inner wall C1 is funnel-shaped, and its inner diameter gradually narrows from the opening 10 towards the second inner wall C2, so as to guide the poured liquid medicine Q to flow into the through hole V below. The second inner wall C2 is generally cylindrical, and its inner diameter is relatively uniform, so as to stably control the flow rate and direction of the liquid medicine Q through the through hole V, thereby further improving the atomization efficiency.
[0030] The atomizing module 4 and the detection module 5 are disposed within the internal space of the cup body 1. The atomizing module 4 is positioned directly above the through-hole V, while the detection module 5 is further positioned above the atomizing module 4. Figure 4 As shown, the storage tank C contains liquid medicine Q.
[0031] Please refer to the following: Figure 3 , Figure 4 and Figure 5 , Figure 5 This diagram illustrates the vertical projection correspondence between the detection area and the through hole of this invention. The detection module 5 includes a detection area 5R, which is positioned above the through hole V. In other words, if the detection area 5R and the through hole V are vertically projected along a vertical direction (i.e., the Z-axis direction) onto an imaginary horizontal projection plane (not shown in the figure), the vertical projection A1 of the detection area 5R and the vertical projection A2 of the through hole V can be obtained.
[0032] In this embodiment of the invention, the area of vertical projection A1 is smaller than the area of vertical projection A2, and vertical projection A1 is completely located within the range of vertical projection A2. That is, the vertical projection A1 of the detection area 5R does not exceed the boundary of the vertical projection A2 of the through hole V. Optionally, vertical projection A1 is further positioned at the center of vertical projection A2, meaning that the detection area 5R is coaxially aligned with the through hole V. This coaxial alignment design helps improve the sensing accuracy of the detection module 5 for changes in the liquid level in the storage tank C, enabling the detection area 5R to accurately detect the amount of liquid directly above the through hole V, avoiding misjudgments or signal distortion caused by module offset, thereby ensuring the consistency of the residual drug amount and the stability and safety of the atomization operation.
[0033] like Figure 3 and Figure 4 As shown, the atomizing module 4 can be composed of an atomizing plate and piezoelectric material. It primarily utilizes ultrasonic vibration to drive the atomizing plate, converting the liquid medicine Q in the storage tank C into mist particles for the user to inhale. On the other hand, the detection module 5 is a liquid level sensor designed to detect the liquid level of the liquid medicine Q, thereby controlling the start, stop, or replenishment prompts of the atomizing program and controlling the residual amount of liquid medicine Q. For example, the detection module 5 can employ capacitive or resistive liquid level detection methods; this invention is not limited to these methods.
[0034] In an embodiment of this utility model, the detection module 5 may include a metal component 51 and a sensing circuit (not shown in the figure), and the sensing circuit is electrically connected to the metal component 51. For example, the sensing circuit may include components such as a microcontroller and a signal processing unit, but this utility model is not limited thereto. The metal component 51 extends laterally and crosses above the through hole V, and its two ends are fixed to the second inner wall C2 for stable positioning. Furthermore, the metal component 51 is covered with an insulating material P, with only a small portion of it exposed as a sensing point for electrical contact with the liquid drug Q, and the exposed area constitutes the detection area 5R.
[0035] Furthermore, the detection area 5R is located directly above the through hole V, and a first distance H1 between the detection area 5R and the through hole V is smaller than a second distance H2 between the detection area 5R and the opening 10. When the medicine Q is poured into the storage tank C of the cup body 1 during treatment, and the liquid level Q1 is at a certain height, the medicine Q will contact the detection area 5R, causing the sensing circuit to generate a change in resistance (or capacitance). At this time, the liquid level of the medicine Q can be determined by detecting the change in resistance (or capacitance). When the control circuit determines that the liquid level Q1 meets the activation condition, it can drive the nebulization module 4 to start the nebulization action; conversely, when the liquid level Q1 is lower than the detection area 5R, the sensing circuit can stop the nebulization module 4 from starting the nebulization function, and may even issue a low liquid warning to remind the user to replenish the liquid.
[0036] In this invention, by adjusting the first distance H1 between the detection area 5R and the through hole V, the residual amount of drug Q in the storage tank C can be controlled, especially the residual trace amount of drug Q. When the user pours a fixed amount of drug Q into the storage tank C during treatment, and it can be ensured that the residual amount of drug Q in the storage tank C after nebulization treatment is also a fixed amount, the amount of drug Q that has been nebulized can be calculated, and the amount of drug Q that has been nebulized can be used to estimate the user's aerosol inhalation volume.
[0037] See Figure 6 As shown, Figure 6 This is a functional block diagram of the atomizing device according to an embodiment of the present invention. The main unit 2 may include a control module 21, which is electrically connected to the atomizing module 4 and the detection module 5, for integrated control of liquid level detection and atomization operation.
[0038] like Figure 4 and Figure 6 As shown, when the liquid level Q1 of the drug solution Q rises above the detection area 5R, the detection area 5R comes into contact with the drug solution Q. At this time, the detection module 5 detects that the liquid level is up to standard and outputs a detection signal to the control module 21. The control module 21 determines that the drug solution Q is sufficient based on the signal, and then activates the atomization module 4 to atomize the drug solution Q. Next, please refer to... Figure 2 After being atomized by the atomization module 4, the liquid medicine Q is converted into a fine mist and diffuses into the air chamber 30 through the through hole V. Finally, when the user inhales through the nozzle 31, the mist can be introduced into the nozzle 31 from the air chamber 30 and inhaled into the body, completing the inhalation administration of the liquid medicine Q.
[0039] On the other hand, when the liquid level Q1 of the drug solution Q drops below the detection area 5R (not shown in the figure), the detection area 5R is no longer in contact with the drug solution Q. In this case, the detection module 5 will no longer output a detection signal to the control module 21. The control module 21 thus determines that the drug solution Q has reached the expected residual amount, and therefore stops controlling the nebulization module 4, while preventing the nebulization module 4 from continuing to perform nebulization operation in a liquid shortage state.
[0040] like Figure 7 As shown, in another embodiment of this utility model, the metal part 51 of the detection module 5 may also extend only from one side of the inner wall of the cup body 1 to above the through hole V. The metal part 51 is also partially covered by insulating material P, and the exposed part forms the detection area 5R. The detection method of the detection area 5R is the same as that in the aforementioned embodiment, and will not be described in detail here.
[0041] This invention positions the detection area 5R of the detection module 5 directly above the through-hole V, ensuring that the vertical projection A1 of the detection area 5R is entirely within the range of the vertical projection A2 of the through-hole V. Optionally, the vertical projection A1 of the detection area 5R can be positioned at the center of the vertical projection A2. This coaxial design ensures that the detection area 5R faces the main flow area where the liquid medicine Q is intended to enter the through-hole V. With this configuration, when the atomizing device D tilts due to handling or placement during actual use, regardless of the tilt direction or angle, the detection area 5R remains aligned with the area directly above the through-hole V, thus accurately detecting the residual amount of liquid medicine Q within that area.
[0042] Furthermore, even if the user operates the atomizing device D in different postures or environments, causing the cup 1 to tilt to different positions, when the liquid Q is used to the preset residual amount, the detection module 5 can accurately determine the residual amount located directly above the through hole V and maintain the consistency of the residual amount. In other words, when the liquid level Q1 is lower than the detection area 5R, and the sensing circuit stops the operation of the atomizing module 4, the amount of liquid Q initially poured into the storage tank C is subtracted from the consistent residual amount, which is the amount of liquid Q that has been atomized. This alignment design, which places the detection area 5R directly above the through hole V, effectively improves the reliability and consistency of liquid level detection, avoids detection errors or misjudgments of insufficient liquid due to tilting, and thus ensures the accuracy of atomization control.
[0043] Beneficial effects of the embodiments
[0044] This invention employs a structural design where the detection area 5R of the detection module 5 is positioned directly above the through hole V. This design ensures that the vertical projection A1 of the detection area 5R is entirely within the range of the vertical projection A2 of the through hole V, and optionally, it is positioned at the center of the vertical projection A2. With this configuration, when the atomizing device D tilts due to handling or placement during actual use, regardless of the tilt direction or angle, the detection area 5R remains aligned with the area directly above the through hole V, thereby accurately detecting whether the remaining medication Q within that area has reached the preset residual amount.
[0045] Furthermore, since the detection area 5R focuses on detecting the liquid residue area above the through-hole V, the efficiency of liquid usage can be improved. In addition, the design of this invention can also avoid the situation where the system prematurely determines that the liquid is insufficient due to improper configuration of the detection area, thereby interrupting the atomization operation, thus reducing liquid waste and extending the effective usage time after each liquid addition, achieving the dual effect of saving liquid and improving device efficiency.
