Description

Technical Field

[0001] The utility model relates to the technical field of atomizer components, in particular to a negative pressure control air intake structure based on an atomizer. Background Art

[0002] With the popularity and diversification of electronic atomizer devices, users' requirements for user experience and safety are also increasing. Traditional electronic atomizers have many shortcomings in air intake control, especially in meeting users' personalized needs and preventing accidental operation. Specifically, these shortcomings are mainly reflected in the following aspects:

[0003] Fixed air volume: Many existing e-cigarette vaporizers use a fixed air volume design, which cannot be adjusted according to the user's inhalation strength or preference, which limits the user's vaping experience. Some users may prefer a smaller air volume for a more delicate vapor taste, while others may prefer a larger air volume for a stronger inhalation feeling. Summary of the Invention

[0004] In order to overcome the deficiencies of the existing technical solutions, the utility model provides a negative pressure controlled air intake structure based on an atomizer, which can effectively solve the problem of fixed air intake volume raised in the background technology.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a negative pressure controlled air intake structure based on an atomizer, including a mouthpiece, an air duct arranged in the mouthpiece, a shell of the air intake structure, and also includes a negative pressure sensing component that senses the user's inhalation force and an exhaust module that adjusts the air intake volume according to the negative pressure.

[0006] Furthermore, it also includes a circuit board, the negative pressure sensing component is installed on the circuit board, the circuit board is connected to a wire, the other end of the wire is connected to the air extraction module, the circuit board and the air extraction module are electrically connected through the wire, the negative pressure sensing component is arranged on the inner wall of the airway, and the air extraction module is arranged inside the shell.

[0007] Furthermore, the air extraction module is provided with a bracket, a rotating shaft is installed inside the bracket, and two layers of fan blades are provided on the rotating shaft.

[0008] Furthermore, the shell is a cylindrical shell, and the shell is provided with a first air inlet part and a second air inlet part. The air holes of the first air inlet part are long strips and are arranged on the side of the shell, and the air holes of the second air inlet part are honeycomb-shaped and are arranged on the bottom surface of the shell.

[0009] Furthermore, the negative pressure sensing component is provided with a conductive film, and a sliding resistor is provided inside the film. The installation direction of the sliding resistor is consistent with the undulation direction of the film. The film is driven by the pressure difference between the inside and outside of the film to move the sliding resistor and change the electrical signal. The signal processing determines the user's suction force and adjusts the air intake of the exhaust module.

[0010] Furthermore, the thin film includes at least one of a metal film, an oxide semiconductor film, and a metal-polymer mixed film.

[0011] Compared with the prior art, the beneficial effect of the present invention is that the negative pressure sensing component of the clock of the present invention can accurately sense the user's inhalation strength, so that the atomizer can adjust the air intake volume according to the user's actual needs, thereby providing a more personalized user experience.

[0012] Based on the feedback from the negative pressure sensing component, the exhaust module will dynamically adjust the air intake volume. When the user's inhalation force increases, the air intake volume will increase accordingly to meet the user's stronger inhalation needs; conversely, when the user's inhalation force weakens, the air intake volume will also decrease accordingly to avoid waste and discomfort.

[0013] Through precise air intake control, the airflow inside the nebulizer can be ensured to be stable and appropriate, which is conducive to the full atomization of the medicine or other liquids. The atomized particles are smaller and more uniform, which helps to improve the absorption efficiency of the drug. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0022] The following describes the embodiments of the present disclosure through specific examples, and those skilled in the art can easily understand other advantages and effects of the present disclosure from the contents disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. The present disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present disclosure. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure. Example

[0023] like Figure 1-5 As shown, the utility model provides a negative pressure controlled air intake structure based on an atomizer, comprising a mouthpiece 1, an air duct 11 arranged in the mouthpiece 1, a shell 2 of the air intake structure, and also comprising a negative pressure sensing component 7 for sensing the user's inhalation force and an exhaust module 12 for adjusting the air intake volume according to the negative pressure.

[0024] The negative pressure sensing component 7 can accurately sense the user's inhalation strength, so that the atomizer can adjust the air intake volume according to the user's actual needs, thereby providing a more personalized user experience.

[0025] According to the feedback from the negative pressure sensing component 7, the exhaust module 12 will dynamically adjust the air intake volume. When the user's inhalation force increases, the air intake volume will increase accordingly to meet the user's stronger inhalation needs; conversely, when the user's inhalation force weakens, the air intake volume will also decrease accordingly to avoid waste and discomfort.

[0026] Precise air intake control ensures a stable and appropriate airflow inside the nebulizer, facilitating the adequate atomization of medications or other liquids. The atomized particles are finer and more uniform, helping to improve drug absorption efficiency and therapeutic effects.

[0027] See also Figures 1 to 5 , and also includes a circuit board 6, a negative pressure sensing component 7 is installed on the circuit board 6, the circuit board 6 is connected to a wire 5, the other end of the wire 5 is connected to the air extraction module 12, the circuit board 6 and the air extraction module 12 are electrically connected through the wire 5, the negative pressure sensing component 7 is arranged on the inner wall of the airway 11, and the air extraction module 12 is arranged inside the shell 2.

[0028] The circuit board 6 is responsible for integrating and coordinating the work of various components. It transmits the signal of the negative pressure sensing component 7 to the exhaust module 12 and controls the action of the exhaust module 12 as needed. The circuit on the circuit board 6 can amplify, filter, and process the signal generated by the negative pressure sensing component 7 to ensure the accuracy and stability of the signal.

[0029] Negative pressure sensing assembly 7, mounted on the inner wall of airway 11, monitors the user's inhalation strength in real time. When negative pressure sensing assembly 7 detects inhalation, it transmits a signal to extraction module 12 via the circuit board 6. Based on the signal transmitted by negative pressure sensing assembly 7, extraction module 12 dynamically adjusts the airflow. As the user's inhalation strength increases, extraction module 12 increases the airflow to meet the user's needs. Conversely, as the user's inhalation strength decreases, extraction module 12 reduces the airflow to avoid waste and discomfort.

[0030] See also Figure 3 and Figure 4 The exhaust module 12 is provided with a bracket 8, a rotating shaft 9 is installed inside the bracket 8, and two layers of fan blades 10 are provided on the rotating shaft 9.

[0031] The two layers of fan blades 10 can generate a larger air volume at the same rotation speed, can more effectively utilize the power provided by the rotating shaft 9, and inhale and discharge more air. The gap and angle design between the two layers of fan blades 10 can optimize the airflow path, reduce eddy currents and turbulence, and make the airflow smoother and more concentrated, thereby improving the exhaust efficiency.

[0032] The bracket 8 provides a stable supporting platform for the rotating shaft 9 and the fan blades 10, so that the entire air extraction module 12 can remain stable during high-speed rotation, which helps to reduce vibration and noise.

[0033] See also Figure 2 and Figure 3 The shell 2 is a cylindrical shell, and the shell 2 is provided with a first air inlet part 3 and a second air inlet part 4. The air holes of the first air inlet part 3 are long strips and are arranged on the side of the shell 2. The air holes of the second air inlet part 4 are honeycomb-shaped and are arranged on the bottom surface of the shell 2.

[0034] The long strip-shaped air holes are designed to form a larger air intake area on the side, thereby increasing the air intake volume. When the user uses the atomizer, the long strip-shaped air holes on the side can quickly inhale the surrounding air, meeting the air flow requirements during the atomization process.

[0035] Setting the air inlet on the side can better coordinate the airflow entering the shell 2 with the airflow inside the atomizer, help reduce the resistance and vortex of the airflow in the shell 2, improve the stability and uniformity of the airflow, and thus improve the atomization effect.

[0036] The honeycomb-shaped air hole design has good air permeability and uniformity, which can ensure that the bottom air intake maintains uniform airflow distribution when inhaling air.

[0037] See also Figure 1 The negative pressure sensing component 7 is provided with a conductive film 71, and a sliding resistor 72 is provided inside the film 71. The installation direction of the sliding resistor 72 is consistent with the undulation direction of the film 71. The film 71 is driven by the pressure difference between the inside and outside of the film to move the sliding resistor 72 to change the electrical signal. The signal processing determines the user's suction force and adjusts the air intake of the exhaust module.

[0038] The conductive film 71 can sensitively sense changes in the pressure difference between the inside and outside of the film, which is caused by the negative pressure generated when the user inhales. The fluctuation of the film 71 is directly related to the size of the suction force, thereby achieving accurate sensing of the suction force changes.

[0039] The installation direction of the sliding resistor 72 inside the film 71 is consistent with the undulation direction of the film 71. Therefore, when the film 71 is subjected to pressure fluctuation, the sliding resistor 72 will be driven to move. This movement will change the resistance value and generate a changing electrical signal.

[0040] Based on the suction force, the system adjusts the airflow of the exhaust module through pre-set control logic. When the suction force increases, the system increases the airflow to meet the user's needs; when the suction force decreases, the system reduces the airflow to avoid waste and discomfort.

[0041] The thin film 71 includes at least one of a metal film, an oxide semiconductor film, and a metal-polymer mixed film.

[0042] The present invention can be modified in settings. For example, when the user has a strong suction force, the air extraction module 12 sends air outwards, which increases the difficulty of inhalation for the user, gradually reduces the need for inhalation, and achieves the withdrawal effect.
