Description

Technical Field

[0001] This utility model relates to the field of atomization, specifically to a gas collection structure for an atomizer and an atomizer. Background Technology

[0002] Throughout the user's use of the atomizer, the aerosol concentration and uniformity significantly affect the inhalation experience. Therefore, enhancing the mixing process between external air and aerosol matrix droplets within the atomization chamber, and improving aerosol generation efficiency, plays a crucial role in enhancing the user's inhalation experience.

[0003] When an atomizer is working, the aerosol generating matrix is ​​heated and vaporized by the heating element and diffuses into the atomization chamber. Inside the atomization chamber, the aerosol generating matrix vapor mixes with air and eventually forms an aerosol. Most products on the market are limited by their structural design, with the atomization chamber cross-sectional area significantly larger than the atomization surface. This design has two major drawbacks: 1. After air enters the atomization chamber, it diffuses throughout the entire chamber, with only a portion / a small portion of the air effectively mixing with the aerosol generating matrix vapor to form an aerosol. This results in a noticeable uneven taste of the aerosol generating matrix when inhaled; 2. Due to convective heat transfer, the aerosol may condense on the structural surface during its flow. The larger the atomization chamber, the more heat is dissipated when the aerosol comes into contact with the structural surface, increasing the risk of condensation. Utility Model Content

[0004] In view of this, the present invention provides an air collection structure and an atomizer for an atomizer, which can reduce the flow area of ​​the atomizing chamber and increase the probability of matrix contact between air and the aerosol evaporated from the heating element on the atomizing core.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a gas collection structure for an atomizer, including an atomizing core and an atomizing chamber base. The atomizing core includes a liquid guide and a heating element disposed on the lower surface of the liquid guide. The atomizing chamber base is provided with two gas collection baffles. The bottom surface of the liquid guide covers the upper surface of the gas collection baffles. The atomizing core, the gas collection baffles, and the inner bottom wall of the atomizing chamber base together form an atomizing chamber, forming an assembly position relationship in which the heating element is accommodated in the atomizing chamber base. The two ends of the heating element correspond to the air inlet and air outlet of the atomizing chamber, respectively.

[0006] Furthermore, the distance between the edge of the heating element and the gas collecting baffle is 0.5 to 1 mm, and the gas collecting baffle and the atomizing chamber base are integrally formed.

[0007] Furthermore, the upper surface of the gas collecting baffle is smooth and flat, the liquid guiding shape is cubic, and the height of the gas collecting baffle is such that the upper surface of the gas collecting baffle is in close contact with the bottom surface of the liquid guiding when assembled.

[0008] Furthermore, the air collecting baffle and the atomizing chamber base are integrally molded.

[0009] The second aspect of this utility model provides an atomizer, which includes the aforementioned atomizer gas collection structure.

[0010] Furthermore, the atomizing core is fixed inside the upper end cover of the atomizing chamber, and a sealing element, the atomizing core sealing element, is provided between the upper end cover of the atomizing chamber and the atomizing core.

[0011] Furthermore, the atomizer includes a housing, an atomizer top cap covering the upper surface of the housing, and an atomizer base disposed inside the lower end of the housing.

[0012] Furthermore, the upper end cover of the atomizing chamber is fitted inside the outer shell, and a liquid storage chamber is formed between the upper end cover of the atomizing chamber and the upper end face of the atomizing core and the outer shell. An annular liquid storage chamber seal is provided between the upper end cover of the atomizing chamber and the outer shell.

[0013] Furthermore, the outer shell has vertically arranged air inlet pipe and air outlet pipe on both sides of the liquid storage chamber. The upper end of the air inlet pipe is connected to the air inlet, and the lower end is connected to the air inlet of the atomizing chamber. The lower end of the air outlet pipe is connected to the air outlet of the atomizing chamber, and the upper end is connected to the suction nozzle.

[0014] Furthermore, an upper cap seal is provided between the upper cap of the atomizer and the outer shell.

[0015] The beneficial effects of this utility model are:

[0016] This utility model discloses an air collection structure for an atomizer. Its key feature is that by setting two air collection baffles on the atomizing chamber base, a more concentrated atomizing chamber can be created, maximizing the constraint of the airflow space below the atomizing surface of the atomizing core. This allows most of the air to mix with the aerosol to form matrix vapor, enhancing the mixing process and improving the uniformity of the aerosol flow. Furthermore, the presence of the two air collection baffles reduces the contact area between the aerosol airflow and the atomizing chamber base, lowering the risk of aerosol condensation within the atomizing chamber.

Detailed Implementation

[0030] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0031] refer to Figures 1-3 As shown, the electronic atomizer 100 includes a housing 010, an atomizer base 011, an atomizing component 02 disposed inside the housing 010, a liquid storage chamber 20, and an atomizer top cap 012 covering the top of the housing 010.

[0032] The outer shell 010 has an elliptical cross-section and a sloping top surface. An air inlet 014 is located on one side wall near the top. An atomizer top cover 012 with the same angle is located on the upper end of the outer shell 010. A top cover seal 015 is located between the atomizer top cover 012 and the outer shell 010. A mouthpiece 013 is centrally located on the higher side of the atomizer top cover 012, allowing the user to inhale the aerosol atomized by the atomizer 100. An atomizer base 011 is located at the lower end of the outer shell 010. (Reference) Figure 5 As shown, the atomizer base 011 is provided with a magnetic component 025, which can be used to connect and fix a power supply device (not shown in the figure). The power supply device and the atomizer 100 can be assembled into an aerosol generating device (not shown in the figure).

[0033] refer to Figures 4-11 As shown, the atomizing assembly 02 includes an upper cover 023 for the atomizing chamber and an atomizing core 021 disposed within the upper cover 023. The atomizing core 021 consists of a liquid guide 0212 and a heating element 0211, with the heating element 0211 fixed to the lower surface of the liquid guide 0212. Two electrodes 024 are mounted on the atomizer base 011, penetrating the atomizing chamber base 030. The atomizer base 011 has the atomizing chamber base 030, which has two air-collecting baffles 0301 that restrict a narrow channel. The upper cover 023 for the atomizing chamber is located inside the outer casing 010, and its outer ring is snapped onto the inner wall of the outer casing 010. An air inlet pipe 027 is vertically arranged on the inner wall of one side of the outer casing 010. The upper end of the air inlet pipe 027 is connected to the air inlet 014. An air outlet pipe 028 is vertically arranged on the inner wall of the other side of the outer casing 010. The air outlet pipe 028 and the air inlet pipe 027 are arranged symmetrically. Similarly, the upper end of the air outlet pipe 028 is connected to the nozzle 013.

[0034] refer to Figure 9As shown, the heating element 0211 is fixed to the lower surface of the liquid conductor 0212, and the two electrodes 024 penetrating the atomizing chamber base 030 are in contact with the two ends of the heating element 0211 respectively. The upper surface of the liquid conductor 0212 and the inner wall of the outer shell 010 form a liquid storage chamber 20, which contains an aerosol forming matrix. A liquid storage chamber sealing element 026 is provided along the annular contact surface between the outer shell 010 and the upper end cover 023 of the atomizing chamber to prevent leakage of the aerosol forming matrix along the contact surface between the outer shell 010 and the upper end cover 023 of the atomizing chamber. The liquid guide 0212 has many tiny pores, acting as a capillary. The upper surface of the liquid guide 0212 is in direct contact with the aerosol-forming matrix. Under the influence of gravity, the aerosol-forming matrix can permeate into the liquid guide 0212. To prevent leakage of the aerosol-forming matrix at the contact point between the liquid guide 0212 and the upper end cap 023 of the atomizing chamber, an atomizing core seal 022 is provided at this contact point. The cavity between the lower surface of the atomizing core 021 and the atomizing chamber base 030 forms the atomizing chamber 033. When energized, the heating element 0211 attached to the lower surface of the liquid guide 0212 vaporizes the aerosol-forming matrix that has permeated into the liquid guide, placing it within the atomizing chamber 033. The vaporized aerosol-forming matrix mixes with air to form an aerosol.

[0035] Specifically, this utility model provides a gas collection structure for an atomizer, including an atomizing core 021 and an atomizing chamber base 030 with two gas collection baffles 0301. The height of the gas collection baffles 0301 is such that, during assembly, the upper surface of the gas collection baffles 0301 is in close contact with the lower surface of the liquid guide 0212 on the atomizing core 021. The width between the two gas collection baffles 0301 is such that the heating element 0211 can be accommodated in the cavity formed between the two gas collection baffles 0301, and the distance from the heating element 0211 to either side of the gas collection baffle 0301 is 0.5–1 mm. Too large a distance affects the gas collection effect, while too small a distance causes contact between the gas collection baffles 0301 and the heating element 0211, affecting the atomization of the aerosol formation matrix. (Reference) Figures 8-9As shown, the gas collection structure forms an assembly relationship where the atomizing core 021 is covered on the upper surface of the gas collection baffle 0301 on the atomizing chamber base 030. The gas collection structure forms an atomizing chamber inlet 032 and an atomizing chamber outlet 031 at both ends of the gas collection baffle 0301. The atomizing chamber inlet 032 is connected to the inlet pipe 027, and the atomizing chamber outlet 031 is connected to the outlet pipe 028, thereby forming a gas flow path from the inlet 014, the inlet pipe 027, the atomizing chamber inlet 032, the atomizing chamber 033, the atomizing chamber outlet 031, the outlet pipe 028 to the nozzle 013. The upper surface of the gas collecting baffle 0301 is machined into a smooth and flat end face. The liquid guide 0212 is rectangular in shape with a smooth and flat bottom surface. The heating element 0211 is pressed into the center of the bottom surface of the liquid guide 0212. The four corners of the liquid guide 0212 are rounded. The upper surface of the gas collecting baffle 0301 can avoid the heating element 0211 and fit tightly against the bottom surface of the liquid guide 0212. Together with the bottom surface of the atomizing chamber base 030, it forms a channel with a certain degree of sealing. This channel is the atomizing chamber 033. It should be noted that if the gas collecting baffle 0301 provided in this utility model is not provided, the atomizing chamber is the space enclosed by the atomizing chamber upper end cover 023, the atomizing chamber base 030, and the atomizing core 021 recessed in the atomizing chamber upper end cover 023. Compared with the atomizing chamber 033 enclosed by the gas collecting structure provided in this utility model, the enclosed space is significantly larger, and the airflow is more dispersed.

[0036] The atomizer provided by this utility model has a smooth and flat upper surface on the gas collecting baffle 0301 and a rectangular shape with a smooth and flat bottom surface on the liquid guide 0212. This ensures that even if there is no sealing material on the contact surface between the upper surface of the gas collecting baffle 0301 and the bottom surface of the liquid guide 0212, the aerosol formed in the atomization chamber 033 will not escape to the atomization chamber base 030 outside the restricted area of ​​the gas collecting baffle 0301. This prevents the aerosol formed by the gaseous aerosol forming matrix after being heated and atomized by the heating element 0211 from mixing with the air drawn in by the air inlet pipe 027 and condensing into larger droplets upon contact with the relatively low-temperature atomization chamber base 030. This also prevents larger droplets from accumulating on the atomization chamber base 030 and avoids uneven aerosol concentration, which would affect the user's inhalation experience.

[0037] In some embodiments, the gas collecting baffle 0301 and the atomizing chamber base 030 are integrally formed, which reduces the processing cost. The atomizing core seal 022 is sleeved on the outside of the atomizing core 021. Since the atomizing core seal 022 is elastic, the atomizing core 021 has a certain assembly allowance and can have a suitable amount of displacement in the vertical direction. This also makes it convenient to assemble the atomizing chamber base 030 with the integrally formed gas collecting baffle 0301.

[0038] A gas collecting baffle 0301 is installed on the atomizing chamber base 030. Together with the atomizing core 021, it can reduce the width of the atomizing chamber 033, making the air entering the atomizing chamber 033 more concentrated. This helps to constrain the airflow, strengthen the mixing process in the atomizing chamber, and improve the uniformity of the aerosol. Furthermore, it allows the formed aerosol to flow directly out of the atomizing chamber outlet 031 without contacting the surface of the atomizing chamber base 030 outside the area enclosed by the two gas collecting baffles 0301, thus reducing the risk of aerosol condensation.

[0039] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
