Description

Technical Field

[0001] This application relates to the field of electronic cigarette inhalation detection technology, and in particular to an electronic cigarette inhalation detection device based on the piezoelectric effect of organic matter. Background Technology

[0002] An electronic cigarette is a device that delivers nicotine to the respiratory system through electronic heating. It consists of e-liquid, a heating system, a power source, and a filter. The e-liquid contains nicotine, flavorings, and solvents such as propylene glycol. The working principle of an electronic cigarette is that a built-in battery heats a coil, causing the e-liquid to evaporate and produce vapor. The user inhales this vapor to ingest nicotine. During use, electronic cigarettes often require the use of inhalation detection devices to monitor performance indicators such as inhalation volume, vapor concentration, and resistance value to ensure product quality and user safety.

[0003] Traditional inhalation detection devices mainly rely on capacitance changes, such as cylindrical microphones or silicon microphones. These devices detect inhalation by causing capacitance changes due to deformation. However, this deformation-dependent detection method has certain limitations, such as sensitivity being limited by the degree of deformation, and in some cases, it may not be able to accurately detect inhalation, thus affecting normal use. Utility Model Content

[0004] The purpose of this invention is to solve or at least alleviate the problem that existing electronic cigarette detection devices rely on capacitance changes and are limited by deformation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electronic cigarette inhalation detection device based on the piezoelectric effect of organic materials, comprising an organic piezoelectric material layer for generating self-generating power under deformation or pressure, a signal acquisition circuit for acquiring the generated charge signal, and a signal processing module for processing the charge signal and determining the inhalation action. The organic piezoelectric material layer and the signal acquisition circuit are fixed by adhesive bonding. The signal acquisition circuit and the signal processing module are detachably connected. The signal processing module includes a threshold detection circuit for setting a threshold for the voltage signal and a microprocessor for determining a valid inhalation action. Both the signal acquisition circuit and the signal processing module are provided with an installation mechanism for quick assembly on one side.

[0006] By employing the above technical solution, through the combined action of the organic piezoelectric material layer, the signal acquisition circuit, and the signal processing module, the generated charge signal can be acquired and processed to determine the inhalation action. When the voltage signal exceeds a preset threshold, it is determined to be a valid inhalation action. This solution has advantages such as high sensitivity, no need for specific deformation, small size, and high integration. Therefore, it is suitable for the field of electronic cigarette inhalation detection and can improve the accuracy of inhalation action detection and user experience.

[0007] Optionally, the organic piezoelectric material layer is a polyvinylidene fluoride (PVDF) film.

[0008] Using the above technical solution, PVDF film exhibits good piezoelectric properties and mechanical stability.

[0009] Optionally, the signal acquisition circuit includes a charge amplifier and a voltage converter for amplifying and converting the weak charge signal generated by the organic piezoelectric material layer into a voltage signal that is easy to process.

[0010] Using the above technical solution, the generated charge signal is collected and processed to determine the inhalation action. When the voltage signal exceeds a preset threshold, it is determined to be a valid inhalation action.

[0011] Optionally, the mounting mechanism includes a first mounting shell fixedly mounted on the signal processing module, a second connecting block fixedly mounted on one side of the signal acquisition circuit, a first arc-shaped block fixedly mounted on the bottom outer wall of the second connecting block, a second telescopic rod fixedly mounted inside the first mounting shell, a second telescopic spring sleeved on the second telescopic rod, a second sliding plate fixedly connected to one end of the second telescopic rod, and a second arc-shaped block fixedly mounted on one side outer wall of the second sliding plate.

[0012] Using the above technical solution, the movement of the second arc-shaped block will cause the second sliding plate to move as well. The movement of the second sliding plate will compress the second telescopic rod and the second telescopic spring. Thus, through the combined action of the first arc-shaped block and the second arc-shaped block, the signal acquisition circuit and the signal processing module can be quickly assembled.

[0013] Optionally, the first arc-shaped block and the second arc-shaped block are matched, and a second mounting groove is provided on the top outer wall of the first mounting shell, and the first arc-shaped block is slidably installed in the second mounting groove.

[0014] By adopting the above technical solution, the second mounting slot can be set up to assist in the installation.

[0015] Optionally, a second limiting groove is provided on one side of the outer wall of the first mounting shell, a second limiting block is slidably installed in the second limiting groove, and the second limiting block is fixedly connected to the second sliding plate.

[0016] By adopting the above technical solution, the second limiting groove and the second limiting block can be set to achieve the function of limiting installation.

[0017] Optionally, the mounting mechanism further includes a second mounting shell fixedly mounted on the signal processing module. A first connecting block is fixedly mounted on one side of the signal acquisition circuit. Two first telescopic rods are symmetrically fixedly mounted inside the second mounting shell. A first telescopic spring is sleeved on each of the two first telescopic rods. A first sliding plate is fixedly mounted on one end of each of the two first telescopic rods. A second inclined block is fixedly mounted on one side of the outer wall of each of the two first sliding plates. A first inclined block is fixedly mounted on the bottom outer wall of the first connecting block.

[0018] By adopting the above technical solution, the two second inclined blocks move away from each other, which in turn causes the two first sliding plates to move away from each other as well. This compresses the corresponding first telescopic rod and the first telescopic spring. Thus, through the cooperation of the first and second inclined blocks, they can be positioned and installed, and the signal acquisition circuit and signal processing module can be quickly assembled.

[0019] Optionally, the second mounting shell has a first mounting groove for mounting the first inclined block. Two first limiting grooves are symmetrically opened on one inner wall of the second mounting shell. A first limiting block is slidably installed in each of the two first limiting grooves. The two first limiting blocks are fixedly connected to the corresponding first sliding plate. A sliding groove is opened on one outer wall of the second mounting shell. A sliding block is slidably installed in the sliding groove and is fixedly connected to one of the first sliding plates.

[0020] By adopting the above technical solution, the sliding block can be slidably installed inside by setting a sliding groove.

[0021] In summary, the beneficial effects of this application are as follows:

[0022] 1. In this application, a signal acquisition circuit and other components are used in conjunction with an organic piezoelectric material layer, signal acquisition circuit, and signal processing module to acquire and process the generated charge signal, determine the intake action, and determine a valid intake action when the voltage signal exceeds a preset threshold. This approach has advantages such as high sensitivity, no need for specific deformation, small size, and high integration. By utilizing the self-generating characteristic of organic piezoelectric materials under pressure regardless of deformation, accurate detection of intake action is achieved, improving the sensitivity and reliability of detection.

[0023] 2. In this application, the new invention utilizes a second mounting shell, etc., to enter the second shell through the first mounting groove. This pushes the two second inclined blocks away from each other, causing the two first sliding plates to move away from each other as well. This compresses the corresponding first telescopic rod and first telescopic spring. Through the cooperation of the first and second inclined blocks, the device can be positioned and installed, and the signal acquisition circuit and signal processing module can be quickly assembled. This improves the convenience and flexibility of later installation. Attached Figure Description

The signal processing module 3 includes a threshold detection circuit 301 for setting a threshold for the voltage signal and a microprocessor 302 for determining a valid inhalation action. Both the signal acquisition circuit 2 and the signal processing module 3 have a mounting mechanism on one side for quick assembly. The organic piezoelectric material layer 1 is made of polyvinylidene fluoride (PVDF) film. The signal acquisition circuit 2 includes a charge amplifier and a voltage converter for amplifying and converting the weak charge signals generated by the organic piezoelectric material layer into voltage signals that are easy to process.

[0032] When in use, the organic piezoelectric material layer, signal acquisition circuit and signal processing module work together to collect and process the generated charge signal to determine the inhalation action. When the voltage signal exceeds the preset threshold, it is judged as a valid inhalation action. It has the advantages of high sensitivity, no need for specific deformation, small size and high integration. Therefore, it is suitable for the field of electronic cigarette inhalation detection and can improve the accuracy of inhalation action detection and user experience.

[0034] In use, when the signal acquisition circuit 2 and the signal processing module 3 are assembled, the first arc-shaped block 12 will enter the first mounting shell 4 through the second mounting slot 10, and will push the second arc-shaped block 20 to move as well. The movement of the second arc-shaped block 20 will also drive the second sliding plate 21 to move as well. The movement of the second sliding plate 21 will compress the second telescopic rod 22 and the second telescopic spring 23. Thus, through the cooperation of the first arc-shaped block 12 and the second arc-shaped block 20, the signal acquisition circuit 2 and the signal processing module 3 can be quickly assembled.

[0035] Example 2

[0036] Reference Figure 3 and Figure 4 The mounting mechanism also includes a second mounting shell 5 fixedly mounted on the signal processing module 3, a first connecting block 9 fixedly mounted on one side of the signal acquisition circuit 2, two first telescopic rods 16 symmetrically fixedly mounted inside the second mounting shell 5, two first telescopic springs 17 sleeved on the two first telescopic rods 16, two first sliding plates 15 fixedly mounted on one end of the two first telescopic rods 16, a second inclined block 14 fixedly mounted on the outer wall of one side of the two first sliding plates 15, a first inclined block 13 fixedly mounted on the bottom outer wall of the first connecting block 9, and a first mounting groove 8 for mounting the first inclined block 13 on the second mounting shell 5, two first limiting grooves 18 opened on the inner wall of one side of the second mounting shell 5, two first limiting blocks 19 slidably mounted in the two first limiting grooves 18, and both first limiting blocks 19 are fixedly connected to the corresponding first sliding plate 15, a sliding groove 6 opened on the outer wall of one side of the second mounting shell 5, and a sliding block 7 slidably mounted in the sliding groove 6, and the sliding block 7 is fixedly connected to one of the first sliding plates 15.

[0037] In use, the first arc-shaped block 12 enters the first mounting shell 4 through the second mounting groove 10, and pushes the second arc-shaped block 20 to move as well. The movement of the second arc-shaped block 20 will also drive the second sliding plate 21 to move as well. The movement of the second sliding plate 21 will compress the second telescopic rod 22 and the second telescopic spring 23.

This device can be integrated into an electronic cigarette device. Then, through the cooperation of the organic piezoelectric material layer 1, the signal acquisition circuit 2, and the signal processing module 3, the generated charge signal can be acquired and processed to determine the inhalation action. When the voltage signal exceeds a preset threshold, it is determined to be a valid inhalation action. Therefore, it has the advantages of high sensitivity, no need for specific deformation, small size, and high integration. Thus, it is suitable for the field of electronic cigarette inhalation detection and can improve the accuracy of inhalation action detection and user experience.

[0039] When the signal acquisition circuit 2 and the signal processing module 3 are assembled, the first inclined block 13 will enter the second housing 5 through the first mounting groove 8, and will push the two second inclined blocks 14 away from each other. The two second inclined blocks 14 moving away from each other will also cause the two first sliding plates 15 to move away from each other, thereby compressing the corresponding first telescopic rod 16 and the first telescopic spring 17. Thus, through the cooperation of the first inclined block 13 and the second inclined block 14, they can be positioned and installed, and the signal acquisition circuit 2 and the signal processing module 3 can be quickly assembled.

[0040] When the signal acquisition circuit 2 and the signal processing module 3 are assembled, the first arc-shaped block 12 will enter the first mounting shell 4 through the second mounting slot 10, and will push the second arc-shaped block 20 to move as well. The movement of the second arc-shaped block 20 will also drive the second sliding plate 21 to move as well. The movement of the second sliding plate 21 will compress the second telescopic rod 22 and the second telescopic spring 23. Thus, through the cooperation of the first arc-shaped block 12 and the second arc-shaped block 20, the signal acquisition circuit 2 and the signal processing module 3 can be quickly assembled. This device has two different composition methods, and the appropriate composition method can be selected according to the usage situation, thus improving the convenience and flexibility of later installation.
