[0030] Example 1

[0031] As Figures 1-5As shown, this embodiment of the invention provides an atomizing component, which includes an upper housing 1, a liquid storage chamber 11 inside the upper housing 1, an atomizing support 2 inside the upper housing 1, an atomizing chamber 21 inside the atomizing support 2, a porous ceramic heating element 211 inside the atomizing chamber 21, a liquid supply channel between the liquid storage chamber 11 and the atomizing chamber 21, and a pressure balancing structure on the atomizing support 2, so that the atomized airflow in the atomizing chamber 21 can balance the pressure in the liquid storage chamber 11 through the pressure balancing structure.

[0032] In this embodiment, the atomizing assembly includes an upper housing 1, within which a liquid storage chamber 11 is constructed, containing atomizing liquid. An atomizing support 2 is also disposed within the upper housing 1, containing an atomizing chamber 21. A porous ceramic heating element 211 is disposed within the atomizing chamber 21. A liquid supply channel connects the liquid storage chamber 11 and the atomizing chamber 21, guiding the atomizing liquid from the liquid storage chamber 11 to the porous ceramic heating element 211 within the atomizing chamber 21. Heating the atomizing liquid produces aerosol. In this embodiment, the atomizing support 2 has a pressure balancing structure. The atomized airflow in the atomizing chamber 21 can balance the air pressure in the liquid storage chamber 11 through the pressure balancing structure. Since the pressure of the atomized airflow in the atomizing chamber 21 is greater than the atmospheric pressure, the liquid storage chamber 11 can provide atomizing liquid to the porous ceramic heating element 211 in a sufficient and continuous manner. This can prevent the problem of insufficient or no atomizing liquid supply, which can easily lead to wick clogging, improve the stability of the product, and enhance the user experience.

[0033] In addition, compared to the pressure balance structure where one end is connected to the atmosphere and the other end is connected to the liquid storage chamber 11, the pressure balance structure of this embodiment increases the flow rate and pressure in the atomizing chamber 21 when the user inhales. At this time, the pressure difference between the atomizing chamber 21 and the liquid storage chamber 11 is greater, and the gas will enter the atomizing chamber 21 more quickly through the pressure balance structure, thus achieving rapid gas replenishment.

[0034] One end of the pressure balancing structure is connected to the atomizing chamber 21, and the other end is connected to the liquid storage chamber 11. The shape of the channel of the pressure balancing structure is not limited and can be any shape. The entire channel of the pressure balancing structure is not limited in shape. The openings of the pressure balancing structure that connect to the atomizing chamber 21 and the openings that connect to the liquid storage chamber 11 are not limited in shape and can be any shape such as circular, elongated, or semi-circular.

[0035] In some embodiments, the air pressure balancing structure includes a flow channel 31 disposed on the outer wall and / or inside the atomizing bracket 2. One end of the flow channel 31 is connected to the atomizing chamber 21, and the other end of the flow channel 31 is connected to the liquid storage chamber 11. By using the flow channel 31 on the outer wall and / or inside the atomizing bracket 2, the atomized airflow in the atomizing chamber 21 can balance the air pressure in the liquid storage chamber 11. This can prevent the atomizing liquid from being unable to be supplied or insufficiently supplied, which could lead to the problem of easy clogging of the coil, thereby improving the stability of the product and enhancing the user experience.

[0036] In some embodiments, the flow channel 31 is a Tesla valve structure. The airflow acceleration direction of the Tesla valve structure is from the atomizing chamber 21 toward the liquid storage chamber 11. The characteristics of the Tesla valve structure enable the atomized airflow in the atomizing chamber 21 to quickly balance the air pressure in the liquid storage chamber 11, thereby achieving rapid air replenishment.

[0037] In some embodiments, the number of flow guiding channels 31 is at least one; there may be one or more flow guiding channels 31, such as... Figure 2 and 3 As shown, a flow channel 31 is provided on each side of the outer wall of the atomizing bracket 2, or two flow channels 31 can be provided. The two flow channels 31 on each side can be symmetrically arranged front and back. The two ends of all the flow channels 31 are connected to the atomizing chamber 21 and the liquid storage chamber 11 respectively. The more flow channels 31 there are, the better the air replenishment effect. The specific arrangement should be based on actual needs.

[0038] In some embodiments, the pressure balancing structure further includes a baffle 32 disposed on at least one side of the atomizing chamber 21 to form a gas storage chamber 33 on at least one side of the atomizing chamber 21. The baffle 32 has a first through hole 34 that connects the gas storage chamber 33 and the atomizing chamber 21. The atomizing support 2 has a second through hole 35 that connects the flow channel 31 and the gas storage chamber 33. The airflow in the atomizing chamber 21 is guided into the gas storage chamber 33 through the first through hole 34 on the baffle 32, and then the gas in the gas storage chamber 33 is guided into the flow channel 31 through the second through hole 35 on the atomizing support 2, thereby finally replenishing the liquid storage chamber 11 with gas.

[0039] In some embodiments, a fixing seat 22 is constructed on the atomizing bracket 2, and a silicone mounting seat 23 is disposed inside the fixing seat 22. A porous ceramic heating element 211 is disposed on the silicone mounting seat 23. A baffle 32 is disposed at the end of the fixing seat 22 away from the liquid storage chamber 11. A first through hole 34 is opened at the position of the baffle 32 near the inner wall of the upper housing 1. There can be multiple first through holes 34, which can separate the replenishing airflow from the atomizing chamber 21, so that the two airflows do not interfere with each other, and provide a high replenishing effect.

[0040] In some embodiments, the gas storage cavity 33 is provided with a liquid suction member 331, which can absorb the condensate carried in the gas flow. The baffle 32 abuts against the liquid suction member 331, and the baffle 32 presses down on the liquid suction member 331 to prevent the liquid suction member 331 from shifting.

[0041] In some embodiments, the pressure balancing structure further includes a flow channel 36 disposed on the outer wall and / or inside the atomizing support 2. A support silicone 5 is disposed between the liquid storage chamber 11 and the atomizing support 2. The support silicone 5 is provided with a silicone valve plate 51. One end of the flow channel 36 is connected to the guide channel 31, and the other end of the flow channel 36 abuts against the silicone valve plate 51. When the atomizing chamber 21 is working, the pressure is greater than the pressure difference between atmospheric pressure and the liquid storage chamber 11. When the pressure difference between the liquid storage chamber 11 and the atomizing chamber 21 is too large, the gas enters the guide channel 31 faster and with greater driving force, making it easier to push open the silicone valve plate 51 on the support silicone 5, thereby achieving efficient one-way gas replenishment.

[0042] In some embodiments, an air intake pipe 12 is constructed inside the upper housing 1. One end of the air intake pipe 12 is constructed with a nozzle 13 that communicates with the outside of the upper housing 1, and the other end of the air intake pipe 12 is connected to the atomizing chamber 21 to form an air outlet channel of the atomizing chamber 21.

[0044] This invention also provides an aerosol forming apparatus, which includes a battery cell assembly and an atomizing assembly as described in Embodiment 1. The battery cell assembly includes a lower housing 41 and a battery cell 42 installed in the lower housing 41. The battery cell 42 is connected to the porous ceramic heating element 211 and provides power to the porous ceramic heating element 211. An air inlet 43 is provided on the lower housing 41 to communicate with the atomizing chamber 21, forming an air inlet channel for the atomizing chamber 21.
