Description

Atomizing device

Technical field

The present disclosure generally relates to a vaporization device, and in particular, to an electronic device that provides an aerosol.

Background technique

An electronic cigarette is an electronic product that heats and atomizes a vaporizable solution and generates an aerosol for users to inhale. In recent years, major manufacturers have begun to produce all kinds of electronic cigarette products. Generally speaking, an electronic cigarette product includes a casing, an oil storage chamber, an atomization chamber, a heating component, an air inlet, an air flow channel, an air outlet, a power supply device, a sensing device, and a control device. The oil storage chamber is used to store vaporizable solution, and the heating component is used to heat and atomize the vaporizable solution and generate aerosol. The air inlet and the atomizing chamber communicate with each other, and provide air to the heating assembly when the user inhales. The aerosol generated by the heating element is first generated in the atomization chamber, and then inhaled by the user through the air flow channel and the air outlet. The power supply device provides the power required by the heating element, and the control device controls the heating time of the heating element according to the user's inhalation action detected by the sensing device. The outer shell covers the above-mentioned components.

Existing electronic cigarette products can use sensors to detect the user's inhalation action. In order to detect the airflow, the sensor has a part communicating with the airflow channel. Vaporizable solution or condensed liquid may infiltrate the part where the sensor communicates with the airflow channel during use by the user, and cause the sensor to malfunction or fail.

In addition, the existing electronic cigarette products do not consider the pressure balance of the oil storage chamber. In existing electronic cigarette products, the oil storage chamber is generally designed to be completely sealed to prevent the vaporizable solution from overflowing. As users continue to use electronic cigarette products, the vaporizable solution in the oil storage chamber is continuously consumed and reduced, so that the pressure in the oil storage chamber becomes smaller and a negative pressure is formed. The negative pressure makes it difficult for the gasifiable solution in the oil storage chamber to evenly flow to the heating component, so that the heating component does not uniformly adsorb the gasifiable solution. At this time, when the temperature of the heating element rises, there will be a high probability of empty burning and a burnt smell, resulting in a bad user experience.

Therefore, an atomization device that can solve the above-mentioned problems is proposed.

Summary of the invention

In some embodiments, the distance h3 is not zero. In some embodiments, the ratio of the distance h3 to the distance h2 is in the range of 0.1 to 0.5. In some embodiments, the ratio of the distance h3 to the distance h2 is in the range of 0.5 to 0.9.

The upper cover 5 of the heating assembly has an opening 5h5 on the surface 5s2. The air flow can reach the opening 5h4 on the surface 5s1 from the opening 5h5 through the second portion 5v2 and the first portion 5v1.

As shown in FIG. 4A, the mouthpiece cover 1 has an opening 1h. The cartridge case 3 has a tube 3t extending from the opening 1h to the upper cover sealing assembly 4. The tube 3t, the upper cover sealing assembly 4 and the cartridge housing 3 define a liquid storage compartment 20. The gasifiable material can be stored in the liquid storage tank 20.

The tube 3t may have a part extending into the channel 5c1. The tube 3t may have an uneven outer diameter. As shown in FIG. 4A, a part of the tube 3t extending into the channel 5c1 has a smaller outer diameter. The tube 3t may have an uneven inner diameter. As shown in FIG. 4A, a part of the tube 3t extending into the channel 5c1 has a smaller inner diameter.

The tube 3t is coupled to the channel 5c1 through the opening 5h1 of the upper cover 5 of the heating assembly. The tube 3t is in fluid communication with the channel 5c1 through the opening 5h1 of the upper cover 5 of the heating assembly. The channel 5c1 is isolated from the liquid storage tank 20 by a pipe 3t.

As shown in FIG. 4A, the upper cover sealing assembly 4 can expose the openings 5h1, 5h2, and 5h3 of the upper cover 5 of the heating assembly. The upper cover sealing assembly 4 does not cover the openings 5h1, 5h2, and 5h3 of the upper cover 5 of the heating assembly. The upper cover sealing assembly 4 does not block the channels 5c1, 5c2, and 5c3.

The channel 5c2 is in fluid communication with the groove 7c of the heating assembly 7. The channel 5c3 is in fluid communication with the groove 7c of the heating assembly 7. The e-liquid stored in the liquid storage tank 20 can flow into the groove 7c through the channel 5c2. The e-liquid stored in the liquid storage tank 20 can flow into the groove 7c through the channel 5c3. The groove 7c of the heating assembly 7 is in fluid communication with the liquid storage compartment 20. The e-liquid can fully contact the heating assembly 7 in the groove 7c. The heating circuit on the surface or inside of the heating component 7 can heat the e-liquid and generate aerosol.

An atomization chamber 8C is defined between the heating element base 8 and the heating element 7. The heating assembly 7 is partially exposed in the atomization chamber 8C. The aerosol generated by heating by the heating element 7 is formed in the atomizing chamber 8C. The aerosol generated by heating by the heating element 7 is ingested by the user through the tube 3t and the opening 1h. The tube 3t is in fluid communication with the atomization chamber 8C. The groove 5r1 (see FIG. 3A) is in fluid communication with the atomizing chamber 6C.

The upper cover sealing assembly 4 can cover the opening 5h4 of the upper cover 5 of the heating assembly. The upper cover sealing assembly 4 can block the passage 5v.

As shown in FIG. 4A, the upper cover 5 of the heating assembly has a blocking member 5p. The barrier 5p isolates the tube 3t from the groove 7c of the heating assembly 7. The barrier 5p isolates the channel 5c1 from the groove 7c of the heating assembly 7.

During the use of the atomizing device, when the condensed liquid remaining in the tube 3t reaches a certain volume, the condensed liquid may slip off the tube 3t. The blocking member 5p prevents the condensed liquid slipped from the tube 3t from contacting the heating element 7. The blocking member 5p can prevent the condensed liquid that slips from polluting the heating assembly 7. The stopper 5p can prevent the slipped condensed liquid from changing the taste of the aerosol. The blocking member 5p can prevent the condensed liquid from slipping to the high-temperature heating element and causing liquid spattering. The stopper 5p can prevent the splashed liquid from scalding the user.

FIG. 4A shows the air flow 8f from the atomization chamber 8C to the liquid storage tank 20.

When the atomizing device is standing and not being sucked by the user, the opening 5h4 is tightly integrated with the upper cover sealing assembly 4, and the e-liquid in the liquid storage compartment 20 will not leak out from the channel 5v.

As the user continues to use the atomizing device, the vaporizable solution in the liquid storage tank 20 is continuously consumed and reduced, so that the pressure in the liquid storage tank 20 gradually decreases. When the pressure in the liquid storage tank 20 decreases, negative pressure may be generated. The decrease of the pressure in the liquid storage tank 20 may make it difficult for the volatile solution to flow to the groove 7c of the heating element 7 through the channels 5c1 and 5c2. When the groove 7c does not completely adsorb the volatile solution, the high-temperature heating element 7 may dry and produce a burnt smell.

The above-mentioned problem can be improved by the channel 5v provided in the upper cover 5 of the heating element. The channel 5v provided in the upper cover 5 of the heating assembly is in fluid communication with the atomization chamber 8C, and can balance the pressure in the liquid storage tank 20.

Since the atomization chamber 8C is in fluid communication with the tube 3t, the pressure in the atomization chamber 8C is approximately equal to one atmosphere. When the vaporizable solution in the liquid storage tank 20 continues to decrease, the pressure in the liquid storage tank 20 is gradually less than one atmospheric pressure. The pressure difference between the atomization chamber 8C and the liquid storage tank 20 causes the airflow 8f to reach the junction between the opening 5h4 and the upper cover sealing assembly 4 from the atomization chamber 8C via the channel 5v. The air flow 8f can partially push the upper cover sealing assembly 4 away. The air flow 8f can cause partial deformation of the upper cover sealing assembly 4. The air flow 8f can enter the liquid storage tank 20 through the gap created by the deformation of the upper cover sealing assembly 4. The airflow 8f entering the liquid storage tank 20 can increase the pressure in the liquid storage tank 20. The air flow 8f entering the liquid storage compartment 20 can balance the pressure between the liquid storage compartment 20 and the atomization chamber 8C.

In some embodiments, the upper cover 5 of the heating assembly may be additionally provided with a channel having the same function as the channel 5v. For example, the upper cover 5 of the heating element may also be provided with a ventilation channel near the opening 5h3.

As shown in FIG. 3A, the channel 5v has an appearance with a narrow top and a wide bottom. The appearance of the channel 5v has many advantages. The 5v channel with narrow top and wide bottom can accelerate the change of air flow. The velocity of the air flow 8f leaving the narrow opening of the channel 5v (5h4) is faster than that of entering the wide opening 5v of the channel (5h5). The accelerated air flow 8f can better open the upper cover sealing assembly 4, and increase the efficiency of pressure balance between the liquid storage tank 20 and the atomization chamber 8C.

Fig. 4B shows a cross-sectional view of a cartridge according to another embodiment of the present disclosure.

The upper cover 5 of the heating assembly includes a channel 5v composed of a first part 5v1 and a second part 5v2 (refer to FIG. 3F). Since the connection between the second part 5v2 and the first part 5v1 is separated by a distance h3 from the bottom surface 5s3, the bottom of the first part 5v1 forms a groove for storing liquid. When the air flow 8f pushes open the upper cover sealing assembly 4, if a small amount of e-liquid leaks into the channel 5v from the opening 5h4 along the gap 201, the groove at the bottom of the first part 5v1 can store the leaked e-liquid and reduce The probability that the smoke oil flows into the main body 100B to cause damage to the electronic components.

Similarly, the first part 5v1 of the channel 5v also has a narrow top and a wide bottom. The appearance of the first part 5v1 can increase the efficiency of pressure balance between the liquid storage tank 20 and the atomization chamber 8C.

The main body 100B includes a sensor holder 9, a connector 10, a sensor 11, a circuit board 12, a flat cable 13, a vibrator 14, a charging assembly 15, a circuit board holder 16, a buffer assembly 17, a power supply assembly 18, a sealing assembly 19, and a frame member 20 , Conductive pins 21, magnetic components 22, power component bracket 23, and main body shell 24.

The sensor bracket 9 can be arranged in the groove 23r3 of the power supply assembly bracket 23. The sensor holder 9 has a groove 9r on one side. The sensor 11 may be arranged in the groove 9r.
