Description

Technical Field

[0001] The present invention relates to the technical field of atomization devices, and particularly to an atomizer and an electronic atomization device thereof. Background Art

[0002] In the prior art, an electronic atomization device mainly consists of an atomizer and a power supply component. The atomizer generally includes a liquid storage cavity and an atomization component. The liquid storage cavity is used for storing an atomizable medium, and the atomization component is used for heating and atomizing the atomizable medium to form an aerosol for a smoker to consume; the power supply component is used for providing energy to the atomizer.

[0003] When the atomizer atomizes the atomizable medium, bubbles are likely to get stuck at the narrowest part of the lower liquid passage during the process of entering the liquid storage cavity from the lower liquid hole, resulting in poor liquid supply to the atomization component, so that the atomizable medium cannot be replenished to the atomization component, causing the atomization component to dry burn and overheat, thereby damaging the atomization component due to poor liquid supply, generating a burnt smell and harmful substances. Summary of the Invention

[0004] The main technical problem to be solved by the present invention is to provide an atomizer and an electronic atomization device thereof, which solve the problem that bubbles are likely to get stuck in the lower liquid passage in the prior art, resulting in poor liquid supply.

[0006] Among them, the liquid in the liquid storage chamber flows to the atomization core through the lower liquid hole. If the pressure in the liquid storage chamber decreases, the flow rate of the liquid in the liquid storage chamber flowing to the atomization core through the lower liquid hole is less than the atomization rate of the atomization core for the liquid, and the outside atmosphere transports gas to the liquid storage chamber through the balanced air pressure structure, so that the air pressure in the liquid storage chamber is balanced with the air pressure of the outside atmosphere.

[0007] Among them, the balanced air pressure structure includes a gas guiding hole structure and a gas guiding groove structure communicated with the gas guiding hole structure. The gas guiding hole structure is provided on the partition, the gas guiding hole structure is communicated with the liquid storage chamber, the gas guiding groove structure is provided on the surface of the partition away from the liquid storage chamber, one end of the gas guiding groove structure is communicated with the outside atmosphere, and the other end is communicated with the gas guiding hole structure.

[0009] Among them, the air guide groove structure is communicated with the air guide hole structure. Both ends of the air guide groove structure extend in a direction away from the air guide hole structure and are communicated with the outside atmosphere through the atomization chamber.

[0010] Among them, the air guide groove structure includes a first air guide groove and a second air guide groove, and the air guide hole structure includes a first air guide hole and a second air guide hole. The first air guide hole and the second air guide hole are arranged at intervals on both sides of the liquid inlet hole.

[0011] Among them, the first air guide groove and the second air guide groove are communicated through a connecting groove.

[0012] Among them, the end of the air guide groove structure communicating with the air guide hole structure extends to the liquid inlet hole, and the air guide groove structure conducts the outside atmosphere, the air guide hole structure and the liquid inlet hole.

[0013] Among them, one end of the air guide groove structure is communicated with the air guide hole structure, and the other end extends in a direction away from the air guide hole structure and is directly communicated with the outside atmosphere.

[0014] Among them, a sealing member is provided between the partition plate and the atomization core, and the sealing member is used to prevent liquid leakage of the balanced air pressure structure.

[0015] Among them, the sealing member abuts against the end of the air guide hole structure connecting the air guide groove structure, and the outer side wall of the sealing member abuts against the opening position of the air guide groove structure, so that an air guide channel is formed between the air guide hole structure and the air guide groove structure between the partition plate and the sealing member.

[0016] To solve the above technical problems, the second technical solution adopted by the present invention is: to provide an electronic atomization device, which includes a power supply component and the atomizer as described above, and the power supply component is used to supply power to the atomizer.

Among them, the balanced air pressure structure communicates the liquid storage chamber with the outside atmosphere and is used to convey gas to the liquid storage chamber to balance the air pressure between the liquid storage chamber and the outside atmosphere. By providing a balanced air pressure structure spaced from the liquid outlet hole on the partition, the present invention makes the liquid flow path and the gas supply path independent of each other, avoiding the phenomenon of bubble blockage in the liquid outlet hole of the liquid flow path. By providing the balanced air pressure structure, the air pressure between the liquid storage chamber and the outside atmosphere can be balanced, solving the problem of poor liquid supply to the atomization core, resulting in dry burning of the atomization core. The structure is simple and easy to implement. BRIEF DESCRIPTION OF THE DRAWINGS

The phrase appearing in various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein may be combined with other embodiments.

[0034] Please refer to Figure 1 、 Figure 2 and Figure 3 , Figure 1 which is a schematic structural diagram of an embodiment of an electronic atomization device provided by the present invention; Figure 2 which is a schematic structural diagram of an embodiment of an atomizer in the electronic atomization device provided by the present invention; Figure 3 is Figure 2 The enlarged structural diagram at position A in. The electronic atomization device 100 can be used for atomizing e-liquid. The electronic atomization device 100 provided in this embodiment includes an atomizer 1 and a main body 2. The atomizer 1 and the main body 2 are detachably connected. Among them, the atomizer 1 specifically includes a liquid storage chamber 10, a mounting base 30, and an atomization core 20.

For details, reference can be made to the prior art and will not be elaborated here.

[0037] As Figure 2 shown, the atomizer 1 generally includes a liquid storage chamber 10, a mounting base 30, an atomization core 20, and a seal 50. Among them, the liquid storage chamber 10 is used to store liquid; the liquid is e-liquid. The mounting base 30 includes a housing 303 and a partition 304 provided on the housing 303. The partition 304 has a liquid outlet hole 314, and a balanced air pressure structure 305 is provided on the partition 304 at an interval from the liquid outlet hole 314; the atomization core 20 is installed in the mounting base 30 and is used for heating and atomizing the liquid; among them, the balanced air pressure structure 305 communicates the liquid storage chamber 10 with the outside atmosphere and is used to transport gas to the liquid storage chamber 10 to balance the air pressure between the liquid storage chamber 10 and the outside atmosphere, so that the liquid reaches the atomization core 20. A seal 50 is provided between the partition 304 and the atomization core 20, and the seal 50 is used to prevent leakage of the balanced air pressure structure 305. Among them, the seal 50 can be a silicone rubber sealing ring.

[0038] The mounting base 30 includes an upper seat body 301 and a lower seat body 302, and the upper seat body 301 and the lower seat body 302 are fixedly connected. Specifically, the upper seat body 301 and the lower seat body 302 can be integrally formed or can be snap-connected by snap-fastening members. An atomization chamber 40 is formed between the lower seat body 302 and the atomization core 20. The atomization core 20 atomizes the e-liquid and forms a smoke in the atomization chamber 40, and the atomization chamber 40 is communicated with the smoke passage 316, and the atomization chamber 40 is communicated with the balanced air pressure structure 305. A sealing rubber seat 312 is arranged at the connection of the upper seat body 301 and the lower seat body 302, and the sealing rubber seat 312 is used for sealing the connection of the upper seat body 301 and the lower seat body 302 to avoid liquid leakage.

[0039] An electrode lead is connected to the lower seat body 302, and the electrode lead is electrically connected to the heating element of the atomization core 20 to supply power to the atomization core 20. An air inlet hole 60 communicated with the atomization chamber 40 is arranged on the surface of the lower seat body 302 facing away from the atomization core 20, and the air inlet hole 60 communicates the atomization chamber 40 with the outside atmosphere. A through hole is also arranged at the position of the sealing rubber seat 312 corresponding to the air inlet hole 60 of the lower seat body 302 for admitting air into the atomization chamber 40, and the gas input through the air inlet hole 60 can be transmitted to the balanced air pressure structure 305 through the atomization chamber 40 and then input into the liquid storage chamber 10 to balance the air pressure between the liquid storage chamber 10 and the outside atmosphere.

[0040] Specifically, the upper seat body 301 includes the above-mentioned housing 303 and a partition plate 304 arranged on the housing 303. A liquid outlet hole 314 is arranged on the partition plate 304, and the liquid outlet hole 314 is communicated with the liquid storage chamber 10, and the liquid outlet hole 314 can make the liquid in the liquid storage chamber 10 be transmitted to the atomization core 20. In this embodiment, the partition plate 304 can divide the space inside the housing 303 into a liquid inlet chamber 313 and an access chamber 318. The liquid inlet chamber 313 and the access chamber 318 can be communicated through the liquid outlet hole 314 and the balanced air pressure structure 305 on the partition plate 304, and a smoke passage 316 is arranged on the housing 303, and the smoke passage 316 is on the same side as the liquid inlet chamber 313, and the smoke passage 316 is used for guiding the smoke to the user's mouth.

[0041] In another alternative embodiment, the partition plate 304 can be connected to one end of the housing 303 facing the liquid storage chamber 10, so that the partition plate 304 does not need to form a liquid inlet chamber 313 with the housing 303; or, the partition plate 304 is connected to one end of the housing 303 facing away from the liquid storage chamber 10, so that the partition plate 304 does not need to form an access chamber 318 with the housing 303. The present application does not limit the specific structure of the mounting base 30, and the following cooperation relationships between the mounting base 30, the atomization core 20, and the sealing member 50 are applicable to various deformed structures of the mounting base 30.

For example, the liquid storage chamber 10 can be a flexible liquid storage tank, a liquid storage ball, etc., which is connected to the partition plate 304 and the liquid storage chamber 10 is communicated with the liquid outlet hole 314.

[0042] The partition plate 304 can be a plate body with a lower liquid hole 314 in the middle and a balanced air pressure structure 305 arranged at intervals around the lower liquid hole 314. Or the partition plate 304 is a plate member with multiple lower liquid holes 314 in the middle, and at least one lower liquid hole 314 is provided with a balanced air pressure structure 305 at intervals around its circumference. As long as the lower liquid hole 314 on the partition plate 304 communicates with the liquid storage chamber 10, and the balanced air pressure structure 305 on the partition plate 304 can communicate the liquid storage chamber 10 and the outside atmosphere, the present application does not limit this.

[0043] Specifically, when the user sucks the electronic atomization device 100, the atomization core 20 atomizes the e-liquid. Along with the user's sucking, the outside air enters the atomization chamber 40 through the air inlet hole 60, and carries the smoke in the atomization chamber 40 to flow through the smoke channel 316 to the user's mouth. At the same time, the gas in the atomization chamber 40 can be transmitted to the liquid storage chamber 10 through the balanced air pressure structure 305, balancing the air pressure in the liquid storage chamber 10, the atomization chamber 40 and the outside atmosphere, so that the e-liquid in the liquid storage chamber 10 can be smoothly transmitted to the atomization core 20 through the lower liquid hole 314, avoiding the situation of dry burning of the atomization core 20.

[0068] Wherein, the liquid in the liquid storage chamber 10 flows to the atomization core 20 through the liquid inlet hole 314. If the pressure in the liquid storage chamber 10 decreases, the speed at which the liquid in the liquid storage chamber 10 flows to the atomization core 20 through the liquid inlet hole 314 is less than the speed at which the atomization core 20 atomizes the liquid, and gas is transmitted to the liquid storage chamber 10 through the air pressure balancing structure 305 to balance the air pressure in the liquid storage chamber 10 with the air pressure of the outside atmosphere.

[0069] In a specific embodiment, when the user sucks the electronic atomization device 100, the atomization core 20 atomizes the e-liquid. The air pressure in the atomization chamber 40 is greater than the air pressure in the liquid storage chamber 10. The atomization chamber 40 is in communication with the outside atmosphere. The air of the outside atmosphere enters the atomization chamber 40 through the air inlet hole 60. The gas in the atomization chamber 40 is squeezed into the first air guide groove 310 and the second air guide groove 311 due to the pressure difference. The gas in the first air guide groove 310 enters the liquid storage chamber 10 through the first air guide hole 308, and the gas in the second air guide groove 311 enters the liquid storage chamber 10 through the second air guide hole 309. The gas is transmitted to the liquid storage chamber 10 through the first air guide hole 308 and the second air guide hole 309, so that the air pressures in the liquid storage chamber 10 and the atomization chamber 40 are balanced. Furthermore, the e-liquid in the liquid storage chamber 10 enters the atomization core 20 through the liquid outlet hole 314, so that the e-liquid in the liquid storage chamber 10 can be smoothly transmitted to the atomization core 20 through the liquid outlet hole 314, avoiding the situation of dry burning of the atomization core 20.

[0070] In a specific embodiment, when the user sucks the electronic atomization device 100, the atomization core 20 atomizes the e-liquid. The air pressure of the outside atmosphere is greater than the air pressure in the liquid storage chamber 10. The air of the outside atmosphere is squeezed into the first air guide groove 310 and the second air guide groove 311 due to the pressure difference. The gas in the first air guide groove 310 enters the liquid storage chamber 10 through the first air guide hole 308, and the gas in the second air guide groove 311 enters the liquid storage chamber 10 through the second air guide hole 309. The gas is transmitted to the liquid storage chamber 10 through the first air guide hole 308 and the second air guide hole 309, so that the air pressures in the liquid storage chamber 10 and the outside atmosphere are balanced. Furthermore, the e-liquid in the liquid storage chamber 10 enters the atomization core 20 through the liquid outlet hole 314, so that the e-liquid in the liquid storage chamber 10 can be smoothly transmitted to the atomization core 20 through the liquid outlet hole 314, avoiding the situation of dry burning of the atomization core 20.

[0071] In a specific embodiment, when the user sucks the electronic atomization device 100, the atomization core 20 atomizes the e-liquid. The air pressure in the atomization chamber 40 is greater than that in the liquid storage chamber 10. The atomization chamber 40 is in communication with the outside atmosphere, and the air of the outside atmosphere enters the atomization chamber 40 through the air inlet hole 60. The gas in the atomization chamber 40 is squeezed into the first air guide groove 310 and the second air guide groove 311 due to the pressure difference. The gas in the first air guide groove 310 enters the liquid storage chamber 10 through the first air guide hole 308. When the amount of gas transmitted by the first air guide groove 310 is greater than the amount of gas transmitted by the first air guide hole 308, the third air guide groove 319 transmits the gas that has not been transmitted in the first air guide groove 310 to the liquid storage chamber 10 through the liquid outlet hole 314. When the amount of gas transmitted by the second air guide groove 311 is greater than the amount of gas transmitted by the second air guide hole 309, the fourth air guide groove 320 transmits the gas that has not been transmitted in the second air guide groove 311 to the liquid storage chamber 10 through the liquid outlet hole 314. The gas is transmitted to the liquid storage chamber 10 through the first air guide hole 308, the second air guide hole 309 and the liquid outlet hole 314, so as to balance the air pressure in the liquid storage chamber 10 and the atomization chamber 40. Furthermore, the e-liquid in the liquid storage chamber 10 enters the atomization core 20 through the liquid outlet hole 314, so that the e-liquid in the liquid storage chamber 10 can be smoothly transmitted to the atomization core 20 through the liquid outlet hole 314, avoiding the situation of dry burning of the atomization core 20.

[0072] An atomizer and an electronic atomization device provided in this embodiment. The atomizer includes a liquid storage chamber for storing liquid; a mounting base, the mounting base includes a housing and a partition provided on the housing, the partition has a liquid outlet hole, and a balanced air pressure structure spaced from the liquid outlet hole is provided on the partition; an atomization core, the atomization core is installed in the mounting base and is used for heating and atomizing the liquid; wherein, the balanced air pressure structure communicates the liquid storage chamber with the outside atmosphere and is used for transporting gas to the liquid storage chamber to balance the air pressure between the liquid storage chamber and the outside atmosphere, so that the liquid reaches the atomization core. The present invention sets a balanced air pressure structure spaced from the liquid outlet hole on the partition, so that the liquid supply path and the gas supply path are independent of each other, avoiding the phenomenon that the liquid supply path is blocked by air bubbles at the liquid outlet hole. By setting the balanced air pressure structure, the balance between the liquid storage chamber and the outside atmosphere can be achieved, solving the problem of poor liquid supply to the atomization core, resulting in dry burning of the atomization core. The structure is simple and easy to implement.
