Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of atomizers, and in particular to an optical sensing module and an atomizer having the optical sensing module. Background Art
[0002] Medical nebulizers are mainly used to administer drugs through the respiratory system. Nebulizers atomize liquid medicine into tiny particles with a specific particle size, and then deliver the converted tiny particles of medicine from the patient's mouth and nose, so that the medicine enters the patient's respiratory system through breathing to achieve the purpose of treatment.
[0003] Existing nebulizers mainly use their internal pressure sensors to perform breathing detection. The pressure sensor is connected to the external environment through a detection hole on the nebulizer host. When the user holds the nozzle of the nebulizer and inhales, the pressure sensor can detect the change in air pressure when the user breathes through the detection hole, that is, the pressure difference generated in the nozzle. However, in this process, the aerosol generated by the liquid medicine or the liquid generated inside the user's mouth and nose may penetrate into the host through the detection hole, causing a short circuit or failure of the circuit board in the host. In addition, in the existing technology of using pressure sensors, before using the nebulizer for breathing detection, the pressure sensor needs to read an initial pressure value first. However, in actual applications, the reading of the initial pressure value will be different depending on whether the user's mouth actually covers the mouthpiece, and the measurement difference of the initial pressure value may cause the breathing detection function to malfunction.
[0004] On the other hand, in the existing technology of using pressure sensors, when the user holds the atomizer to operate, an external force is applied to the atomizer due to the grip of the hand, and the external force causes the inside of the host to be subjected to considerable pressure, which makes it easy for the pressure sensor to generate errors during measurement, thereby affecting the accuracy of the measurement results. Utility Model Content

[0009] In order to solve the above-mentioned technical problems, another technical solution adopted by the utility model is to provide an atomizer, which includes a main unit, a cup body, a nozzle kit, an atomization module and an optical sensing module.

The thin film structure is arranged at the detection hole, and the thin film structure is blocked between the nozzle port and the optical sensor. When the user inhales into the nozzle port, the thin film structure is deformed by the pressure difference generated inside the nozzle port, and the optical sensor is used to detect the deformation amount of the thin film structure.

[0012] Preferably, the atomizer further comprises a hollow tube, which is close to and arranged on a surface of the nozzle kit, and has a connecting opening and a detecting opening, wherein the connecting opening is connected to the optical sensor, and the detecting opening is exposed and adjacent to the nozzle opening.

[0016] Preferably, the atomizer further comprises a control module electrically connected to the atomization module and the optical sensor, and the control module is used to receive the sensing signal and control the activation of the atomization module accordingly.
[0017] One of the beneficial effects of the utility model is that the optical sensing module and the atomizer having the optical sensing module provided by the utility model can be used as a basis for controlling whether to start the atomizer module by setting a thin film structure in the detection hole of the atomizer and detecting the deformation of the thin film structure through an optical sensor.

[0025] It should be understood that, although the terms "first", "second", "third", etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are mainly used to distinguish one element from another element. In addition, the term "or" used herein may include any one or more combinations of the associated listed items depending on the actual situation.
[0026] Example:
[0027] See also Figure 1 , Figure 3 and Figure 4 As shown, the utility model provides an atomizer N including an optical sensing module M. The optical sensing module M is disposed inside the atomizer N. The optical sensing module M mainly includes an optical sensor 1 and a thin film structure 2. The relative positions of the optical sensor 1 and the thin film structure 2 are shown in FIG. Figure 1 In addition, the atomizer N further includes a main unit 3, a cup body 4, a nozzle kit 5 and an atomizing module 6. The cup body 4 is disposed at the head of the main unit 3. The nozzle kit 5 and the atomizing module 6 are disposed at the cup body 4. The main unit 3 has a detection hole 30, and the nozzle kit 5 has a nozzle opening 50.
[0028] like Figure 3 and Figure 4 As shown, the cup body 4 includes a first shell 41 and a second shell 42. The first shell 41 can store liquid medicine. The second shell 42 includes a first interface 421, a second interface 422 and a third interface 423 that are interconnected. The first shell 41 is arranged at the first interface 421. The nozzle kit 5 is arranged at the second interface 422, and the second shell 42 is connected to the head of the host 3 through the third interface 423. The atomization module 6 is arranged at the bottom of the first shell 41. The optical sensor 1 is arranged inside the host 3 of the atomizer N. The film structure 2 is arranged in the detection hole 30 of the host 3 and is used to seal the detection hole 30.
[0029] The optical sensor 1 is a sensor that converts light signals into electrical signals using a photosensitive component. The present invention is not limited to the specific implementation of the optical sensor 1. For example, the optical sensor 1 is mainly composed of a light-emitting portion that transmits light and a light-receiving portion that receives light (not shown). When the light projected by the light-emitting portion is reflected back by the object to be detected and received by the light-receiving portion, the amount of light received by the light-receiving portion will change, and the light-receiving portion will output a sensing signal after detecting the change in the amount of light received.
[0030] like Figure 4As shown, when the cup body 4, the nozzle kit 5 and the main unit 3 are assembled into one, there is a detection channel S1 between the film structure and the optical sensor, and there is a gas channel S2 between the film structure 2 and the nozzle port 50. The detection channel S1 and the gas channel S2 are separated from each other by the barrier of the film structure 2 and are not connected to each other. In the present utility model, since the film structure 2 is arranged in the detection hole 30 of the main unit 3, the internal space of the main unit 3 cannot be connected to the external environment through the detection hole 30. Therefore, the present utility model sets the film structure 2 in the detection hole 30 of the main unit 3 so that the film structure 2 is blocked between the nozzle port 50 and the optical sensor 1, thereby blocking the optical sensor 1 from the external environment, thereby preventing water droplets or water vapor from the external environment from penetrating into the main unit 3 to cause a short circuit or malfunction.
[0031] like Figure 1 and Figure 4 As shown, when the user holds the nozzle opening 50 of the nozzle kit 5 with his lips and inhales ( Figure 1 The direction D in the figure represents the direction toward the nozzle opening 50), the internal gas channel S2 will generate a pressure difference with the detection channel S1 on the other side due to the user's breathing, and the pressure difference causes the film structure 2 to deform. At the same time, the optical sensor 1 can output the light L1 through the detection channel S1 and receive the reflected light L2, and thereby detect the deformation of the film structure 2 and output the aforementioned sensing signal accordingly. For example, the material of the film structure 2 includes an elastomer, and the thickness of the film structure 2 is between 0.01 and 0.05 cm. In another embodiment, the film structure 2 may be a cross-sectional structure in which the central area is thinner than the peripheral area. In addition, the atomizer N of the utility model also includes a control module 9, which is electrically connected to the atomization module 6 and the optical sensor 1. The control module 9 is capable of receiving the sensing signal and sending a control signal according to the sensing signal, thereby controlling the activation of the atomization module 6 to perform an atomization action.
[0032] For example, when the atomizer N is in an unactivated state, when the user presses his lips against the nozzle kit 5 and inhales into the nozzle opening 50, the gas in the gas channel S2 flows to the user's oral cavity, thereby generating an outward negative pressure. The negative pressure causes the film structure 2 to generate a deformation, so that the optical sensor senses the deformation and generates a sensing signal, which is transmitted to the control module 9. The control module 9 outputs a start signal according to the sensing signal to transmit it to the atomization module 6. The atomization module 6 that receives the start signal performs an atomization action to atomize the liquid medicine in the first shell 41 of the cup body 4 to the space below the atomization module 6, so that the liquid medicine in aerosol form is inhaled by the user through the nozzle kit 5.
[0033] On the contrary, when the user stops the inhalation action or moves the lips away from the nozzle kit 5, the gas inside the gas channel S2 does not flow, and thus the optical sensor 1 fails to sense the pressure change. Thus, without providing a sensing signal to the control module 9, the control module 9 will not output any signal to the atomization module 6, and the atomization module 6 will not perform the atomization action.
[0034] See also Figure 2 As shown, Figure 2 The second embodiment of the atomization module is shown in FIG. Figure 2 The detection channel S1 has a gap G to balance the pressure on both sides of the film structure 2 during use. However, water vapor may penetrate through the gap G. Therefore, the detection channel S1 may be provided with a transparent barrier layer 8, so that the transparent barrier layer 8 can block the water vapor entering the detection channel S1 and will not affect the direction of the light L1 and L2.
[0035] In addition, the present invention is not limited to the specific form of the atomizer N. Figure 5 As shown, the present invention provides another atomizer N, and the optical sensing module M is also applicable thereto. Specifically, Figure 5 The atomizer N shown includes an optical sensing module M (including an optical sensor 1 and a film structure 2), a main unit 3, a cup body 4, a nozzle kit 5 and an atomization module 6. Figure 5 The atomizer N shown also includes a hollow tube 7. The hollow tube 7 is close to and disposed on the outer surface of the nozzle assembly 5, and has a connecting opening 701 and a detection opening 702. The connecting opening 701 is connected to the optical sensor 1, and the detection opening 702 is exposed and adjacent to the nozzle opening 50.
[0036] The hollow tube 7 can be a multi-piece tube assembly. Figure 5 As shown, the hollow tube includes a first portion 71 and a second portion 72, and the thin film structure 2 is blocked between the first portion 71 and the second portion 72. The first portion 71 forms a detection channel S1 between the thin film structure 2 and the optical sensor 1, and the second portion 72 forms a gas channel S2 between the thin film structure 2 and the detection opening 702. The gas channel S2 is separated from the gas channel S1 and is not connected to each other.
[0037] It is worth mentioning that in Figure 5In the embodiment, the nozzle opening 50 is aligned with the detection opening 702. Therefore, the pressure change of the air flow near the detection opening 702 of the hollow tube 7 is equivalent to the pressure change of the nozzle opening 50. When the user holds the nozzle kit 5 with his lips to inhale, the detection opening 702 and the nozzle opening 50 also generate negative pressure. Since the pressure change of the nozzle opening 50 is equal to the pressure change of the detection opening 702, the deformation of the film structure 2 caused by the pressure change of the detection opening 702 is equivalent to the deformation of the film structure 2 caused by the pressure change of the nozzle opening 50. In this way, the optical sensor 1 can output a sensing signal by detecting the deformation of the film structure 2 of the hollow tube 7, and transmit the sensing signal to the control module 9. Then, the control module 9 sends a control signal according to the sensing signal to control the start of the atomization module 6.
[0038] Beneficial effects of the embodiments:
[0039] The atomizer N and its optical sensing module M provided by the utility model can be set in the detection hole 30 of the host 3 through the thin film structure 2, and the deformation of the thin film structure 2 can be detected by the optical sensor 1 to serve as the basis for controlling whether to start the atomizer module 6. The atomizer N of the utility model uses the thin film structure 2 to block between the nozzle port 50 and the optical sensor 1, so that the moisture of the external environment will not penetrate into the inside of the atomizer N through the detection hole 30. In addition, the atomizer of the utility model uses an optical sensor to replace the pressure sensor commonly used in the prior art to measure the pressure change. The principle is to judge the user's breathing state by detecting the deformation of the thin film structure through the optical sensor, so as to start the atomizer module when the user is in the inhalation state.
[0040] Furthermore, since the atomizer N provided by the present invention utilizes the optical sensor 1 to detect the deformation of the thin film structure 2 to generate a corresponding sensing signal, it is not necessary to consider the difference in initial pressure like the pressure sensor in the prior art to affect the function of the breathing detection. Furthermore, the thin film structure 2 is less likely to be deformed by the user holding the atomizer N, thereby avoiding the situation in which the pressure sensor in the prior art is prone to generate measurement errors.
