Description

Atomizer

This creation relates to an atomizer, in particular to an atomizer that detects aerosol inside the atomizer by means of optical detection.

A nebulizer is a device that atomizes liquid and is often used in the medical field, such as a medical nebulizer for treating upper respiratory tract, which atomizes medicinal liquid into tiny particles (ie, aerosol) and enters the human respiratory tract and lungs through breathing inhalation It can be deposited on the body, so as to achieve the purpose of painless, rapid and effective treatment.

However, the atomizer in the prior art has a disadvantage, that is, it is impossible to know the remaining amount of the internal liquid medicine. Therefore, it often happens that the liquid medicine is almost used up or has been used up, but the atomization module inside the atomizer is still constantly Running, forming a phenomenon of air vibration. The so-called air vibration means that there is not enough liquid medicine to contact the atomization module to produce aerosol, usually when the liquid medicine is used up. When the atomizer vibrates in the air, it is easy to damage the atomization module and consume too much power.

Therefore, how to overcome the above-mentioned shortcomings through the improvement of structural design has become one of the important issues to be solved by this business.

The first cavity is used for storing medicine liquid. The atomization module is arranged on the partition wall. The partition wall has a first through hole. The atomization module is used for converting the medicine liquid into aerosol and dispersing it in the second cavity through the first through hole. The main body and the cup body are movably joined, and the joint surface of the main body and the cup body is provided with a second through hole. The light detection module is arranged inside the host and corresponds to the second through hole. The light detecting module emits light from the second through hole, and passes through the bottom of the cup body to enter the second cavity to detect the concentration of the aerosol.

One of the beneficial effects of this creation is that the atomizer provided by this creation can pass through “the atomizer includes a cup body, an atomization module, a host, and a light detection module”, “the cup body has a partition wall , The partition wall separates the inside of the cup into a first cavity and a second cavity", "The first cavity is used to store the drug liquid, and the atomization module converts the drug liquid into aerosol and spreads it in the second cavity" , "The atomization module is arranged on the partition wall, the partition wall has a first through hole, and the atomization module is used to convert the drug liquid into aerosol and spread it in the second cavity through the first through hole", "Host and cup The body is joined, and the joint surface of the main body and the cup body has a second through hole" and "the light detection module is arranged inside the main body and corresponds to the second through hole. The light detection module emits at least one light from the second The through hole shoots out and passes through the bottom of the cup and enters the second cavity to detect the concentration of the aerosol. The technical solution is to detect the concentration of the aerosol inside the atomizer to determine the stock of liquid medicine and reduce the fog.

[First Embodiment]

1 to 4, the first embodiment of the present creation provides an atomizer 100, which includes: a cup body 1, an atomization module 2, a host 3, and a light detection module 4. The cup body 1 is movable Ground and host 3 are joined.

The inside of the cup body 1 is provided with a partition wall 11, which divides the inside of the cup body 1 into a first cavity 12 and a second cavity 13, and the first cavity 12 stores medicinal liquid (not shown). The atomization module 2 is arranged on the partition wall 11. The partition wall 11 has a first through hole 111, and the position of the first through hole 11 corresponds to the atomization module 2. Specifically, the first through hole 111 is arranged under the atomization module 2 (as shown in FIGS. 3 and 4), but the present creation is not limited, and the first through hole 111 is arranged under the atomization module 2 In fact, the first through hole 111 may be provided directly below or obliquely below the atomization module 2. The atomization module 2 converts the medicine liquid into an aerosol (not shown) and spreads it in the second cavity 13 through the first through hole 111. The cup 1 has a nozzle 10 through which the aerosol dispersed in the second cavity 13 can be dispersed to the external environment. The host 3 and the cup 1 are joined, and the joint surface 30 between the host 3 and the cup 1 has a first Two through holes 31. The light detecting module 4 is disposed inside the host 3 and corresponds to the second through hole 31.

The light detection module 4 emits light L1, which is emitted upward from the second through hole 31, passes through the bottom 14 of the cup 1 and enters the second cavity 13 to detect the concentration of aerosol, as shown in the figure 4 shown. It should be noted that the above mentioned here includes directly above and obliquely above, that is, the light L1 can be emitted upward from the second through hole 31 at any angle. Since it needs to pass through the bottom 14 of the cup 1, at least a part of the bottom 14 of the cup 1 includes a light-transmitting material. In addition, a transparent wall 15 is provided between the second through hole 31 and the light detection module 4, and the second through hole 31 can also be filled with translucent or transparent material, which is intended to not only allow light to pass through, It can also protect the light detection module 4 inside the host 3.

Next, the operation of the atomizer 100 will be described, first referring to FIG. 9. The light detection module 4 is an optical sensor and includes a transmitting terminal 41 and a receiving terminal 42. The transmitting end 41 emits an optical signal (light L1), and the receiving end 42 is used to receive the optical signal (light L2). When there is no aerosol in the second cavity 13, the receiving end 42 only receives the light L2 reflected and diffused by the interface in the second cavity 13. However, when the second cavity 13 has aerosol, the receiving end 42 will receive the light L2 reflected, diffused and reflected by the aerosol in the second cavity 13. That is to say, the light signal (light L2) received by the receiving end 42 is reflected by the aerosol. When the concentration of the aerosol in the second cavity 13 is high, the light L2 contains a certain proportion of the aerosol-reflected Conversely, when the concentration of aerosol in the second cavity 13 is low, the proportion of light L2 reflected by the aerosol must be lower. In other words, the atomizer 100 uses the ratio of the light L1 (emitted by the light detection module 4) and the light L2 (generated by the interface reflection, diffusion and aerosol reflection in the second cavity 13) to detect aerosol. concentration.

Regardless of whether the light L2 received by the receiving end 42 has been reflected by the aerosol, once the receiving end 42 receives the light signal (light L2), a detection signal A will be sent out. The atomizer 100 of the present creation further includes a control module 5. The control module 5 receives the detection signal A, and converts the detection signal A into a corresponding detection value. When the concentration of the aerosol in the second cavity 13 is high, the detection value corresponding to the detection signal A emitted by the receiving end 42 according to the light signal (light L2) is relatively high. Conversely, when the concentration of aerosol in the second cavity 13 is low, the detection value corresponding to the detection signal A emitted by the receiving end 42 according to the light signal (light L2) is lower.

The control module 5 includes a storage element 51, and the storage element 51 stores a set value, and the set value is a preset standard used to measure whether the medical liquid in the first cavity 12 is sufficient or exhausted. The control module 5 can compare the detected value with the set value, and output the corresponding control signal B to the atomization module 2 according to the comparison result, and the atomization module 2 performs the switching action according to the control signal B.

Furthermore, if the detection value is greater than the set value, it means that the concentration of the aerosol in the second cavity 13 is high, and it also means that the medicine liquid in the first cavity 12 is enough to be continuously transformed into through the atomization module 2 Aerosol. Therefore, at this time, the control module 5 outputs the control signal B to the atomization module 2, so that the atomization module 2 is continuously powered on. Conversely, if the detected value is less than the set value, it means that the concentration of aerosol in the second cavity 13 is low, and it also means that the amount of the medicine liquid in the first cavity 12 is insufficient, so that the atomization module 2 will convert The mist becomes less. Therefore, at this time, the control module 5 outputs the control signal B to the atomization module 2 to power off the atomization module 2.

[Second Embodiment]

Referring to Figures 5 and 6, the difference between the second embodiment and the first embodiment is that the bottom 14 of the cup body has a convex portion 141 protruding inward, and the convex portion 141 will mate when the cup body is movably joined to the host 3 Corresponding to the second through hole 31, the convex portion 141 is positioned above the second through hole 31. The design of the convex portion 141 can prevent condensation of water vapor on the light detecting module 4. Since the atomization module 2 will continuously convert the drug liquid into aerosol and spread it in the second cavity 13, therefore, the bottom 14 of the cup 1 will condense and gather water, which will affect the effect of light passing through and the light detection. The reliability of the detected aerosol concentration of the measuring module 4. In this embodiment, by forming the convex portion 141 above the second through hole 31, the water droplets formed by condensation of the water vapor on the convex portion 141 will slide down due to gravity and will not collect on the convex portion 141.

[Third Embodiment]

Referring to Figures 7 and 8, the difference between the third embodiment and the first and second embodiments is that the bottom 14 of the cup body 1 is a recessed ladder-like structure, and the joint surface 30 of the host 3 is a A raised ladder structure, and the light detecting module 4 is arranged inside the raised ladder structure. The joint surface 30 of the host 3 is designed with a convex ladder-like structure, which is also designed to avoid condensation of water at the light exit of the light detection module 4. As shown in FIG. 8, the light L1 emitted by the light detecting module 4 is emitted from the second through hole 31 to the side. In other words, the light L1 can be emitted from the second through hole 31 to the side at any angle. In other words, the bottom 141 of the cup body 1 is a vertical surface on the light-emitting surface corresponding to the light detection module 4 and the second through hole 31, so the water droplets formed by condensation of water vapor will slide down due to gravity and will not gather in the vertical Surface.

Referring to Figure 10, the first embodiment of the present creation provides a method for detecting aerosol inside an atomizer, which at least includes the following steps:

Step S1: The atomization module 2 is configured to convert the medicine liquid in the first cavity 12 in the cup 1 into aerosol and disperse it in the second cavity 13 in the cup 1.

Step S2: Configure the light detecting module 4 to emit light to detect the concentration of aerosol in the second cavity 13 and emit a detection signal A accordingly.

Step S3: Configure a control module 5 to receive the detection signal A, and convert the detection signal A into a corresponding detection value.

Step S4: Compare the detected value with the set value stored in the control module 5, so that the control module 5 outputs the corresponding control signal B to the atomization module 2 according to the comparison result, and makes the atomization module 2 follow The control signal B performs the switching action.

In step S4, the atomization module 2 performs the switching action according to the control signal B, which means that when the detection value is greater than the set value, it indicates that the concentration of aerosol in the second cavity 13 is high, that is, the first cavity 12 The drug liquid inside is sufficient. Therefore, at this time, the control module 5 outputs the control signal B to the atomization module 2, so that the atomization module 2 is continuously powered on. Conversely, if the detected value is less than the set value, it means that the aerosol concentration in the second cavity 13 is low, that is, the medicine liquid in the first cavity 12 is insufficient. Therefore, at this time, the control module 5 outputs the control signal B to the atomization module 2 to power off the atomization module 2.

Test signal A", "Configure control module 5 to receive detection signal A, and convert the detection signal A into a corresponding detection value" and "Compare the detection value with the setting value stored in control module 5 to Make the control module 5 output the corresponding control signal B to the atomization module 2 according to the comparison result, and make the atomization module 2 execute the switch action according to the control signal, so as to use the detection of the internal atomizer 100 The aerosol concentration judges the stock of the liquid medicine and reduces the probability of air vibration of the atomization module 2.

Furthermore, different from the prior art, the prior art uses electrical components to detect whether there is a residual amount of drug liquid through the change of electrical properties (resistance, current, voltage, etc.). Use the optical sensing element (light detection module 4) to receive different values with or without aerosol to determine whether there is aerosol stored in the second cavity 13, and when the received value is lower than a certain value, It is determined that the atomization of the drug liquid is completed, and the atomization action of the atomization module 2 is stopped.

In addition, compared with the prior art, the optical sensing element (light detection module 4) and the atomization module 2 are placed in the same space for the atomization module 2 to perform detection actions.

By arranging the optical sensing element and the atomization module 2 on different objects, the aerosol generated by the atomization module 2 will not directly contact the optical sensing element. The advantage of this is that the optical sensing element does not contact the aerosol, which can avoid the possibility that the optical sensing element will dissolve into the aerosol and affect the properties of the drug. Furthermore, the cup object is a replaceable object, and the optical sensing element is placed on the host, which can reduce the number of assembly elements of the atomizer 100 as a whole, and reduce the consumption and waste of elements.
