[0028] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] See also Figures 1 to 6 The present invention provides an electronic atomization device with balanced liquid supply, which includes a housing 1, a liquid storage component 2, an atomization core 3, a battery 4 and a controller 5. The housing 1 is a columnar structure, which is provided with a mist outlet 11. The mist outlet 11 is located at one end of the liquid storage component 2. During operation, the mist is discharged from the mist outlet 11. The liquid storage component 2 is located in the housing 1, and includes a liquid storage tube 21, a ventilation tube 22, a top cover 23 and a base 24. The liquid storage tube 21 is located in the housing 1, and the ventilation tube 22 is located in the liquid storage tube 21 and is coaxially arranged with the liquid storage tube 21. The first end of the ventilation tube 22 is connected to the top cover 23, and the second end of the ventilation tube 22 is connected to the base 24.

[0030] The top cover 23 is provided at the top end of the liquid storage tube 21 and extends into the liquid storage tube 21. The base 24 is provided at the bottom end of the liquid storage tube 21 and extends into the liquid storage tube 21. A liquid storage chamber 25 is formed between the liquid storage tube 21 and the ventilation tube 22, and the liquid storage chamber 25 is used to store the atomized liquid, and the atomized liquid can be a refreshing substance such as a mint atomized liquid, a lemon atomized liquid, etc. It can be understood that the specific substance of the atomized liquid is not specifically limited here, and it can be selected as needed. An atomizing chamber 26 connected to the mist outlet 11 is formed in the ventilation tube 22, and the aerosol in the atomizing chamber 26 can flow to the mist outlet 11, and a liquid inlet hole 27 is provided at the cavity wall of the atomizing chamber 26.

[0031] The liquid inlet hole 27 includes a liquid inlet section 271, a first turning section 272 and a second turning section 273. The liquid inlet section 271 is located at the outer wall of the atomizing chamber 26 and is arranged along the lateral extension of the liquid storage component 2, that is, the liquid inlet section 271 is arranged along the lateral extension of the ventilation pipe 22. The first turning section 272 is located between the outer wall surface and the inner wall surface of the atomizing chamber 26 and is arranged along the longitudinal extension of the liquid storage component 2, that is, the first turning section 272 is arranged along the longitudinal extension of the ventilation pipe 22, and the extension direction of the first turning section 272 is perpendicular to the extension direction of the liquid inlet section 271. The first end of the first turning section 272 is connected to the liquid inlet section 271, and the second end of the first turning section 272 is connected to the second turning section 273. The second turning section 273 is located at the inner wall surface of the atomizing chamber 26 and is arranged around the inner wall surface of the atomizing chamber 26, and the first turning section 272 and the second turning section 273 are perpendicular to each other.

[0032] Since the extension direction of the first turning section 272 is perpendicular to the extension direction of the liquid inlet section 271, when the atomized liquid fluctuates laterally due to the action of external force, it is not easy for the atomized liquid to quickly flow into the atomizing chamber 26 through the obstruction of the first turning section 272. Since the first turning section 272 and the second turning section 273 are perpendicular to each other, the atomized liquid flowing from the first turning section 272 changes its flow direction after entering the second turning section 273, thereby reducing the impact force.

[0033] The inner wall surface of the atomizing chamber 26 is also provided with a first liquid guide groove 274 and a second liquid guide groove 275. The first liquid guide groove 274 is located on the first side of the second turning section 273 and is extended along the longitudinal direction of the atomizing chamber 26. The first liquid guide groove 274 is connected to the second turning section 273. The first liquid guide groove 274 is located above the second turning section 273. There are several first liquid guide grooves 274, and the first liquid guide grooves 274 are spaced apart from each other. Therefore, not only can the impact force of the atomized liquid flowing out of the second turning section 273 be dispersed, but also the atomized liquid can be quickly conducted to the upper half of the atomizing core 3, which can better avoid the problem of dry burning due to insufficient supply of atomized liquid.

[0034] The number of the second liquid conducting grooves 275 is several, and the second liquid conducting grooves 275 are spaced apart from each other. The second liquid conducting grooves 275 are located on the second side of the second turning section 273, and are arranged along the longitudinal extension of the atomizing chamber 26. The second liquid conducting grooves 275 are connected to the second turning section 273, and the first side of the second turning section 273 and the second side of the second turning section 273 are arranged relative to each other. Therefore, not only can the impact force of the atomized liquid flowing out of the second turning section 273 be dispersed, but also the atomized liquid can be quickly conducted to the lower half area of ​​the atomizing core 3, so as to better avoid the problem of dry burning due to insufficient supply of atomized liquid. The straight line where the first liquid conducting groove 274 is located is parallel to the straight line where the second liquid conducting groove 275 is located, so that the atomized liquid can be evenly dispersed and supplied to the atomizing core 3, avoiding the problem of oversaturation or insufficient supply of atomized liquid.

[0035] The atomization core 3 includes a liquid-absorbing cotton tube 31, an electric heating element 32, a fixed tube 33 and a liquid-blocking glass fiber tube 34 formed by weaving glass fibers. The liquid-absorbing cotton tube 31 is located in the atomization chamber 26 for adsorbing atomized liquid. The liquid-absorbing cotton tube 31 can be formed by winding cotton cloth, or by winding cotton cloth and non-woven fabric after being nested with each other. The electric heating element 32 is attached to the inner wall surface of the liquid-absorbing cotton tube 31 and is electrically connected to the controller 5. The electric heating element 32 can be a resistance wire or an electric heating plate. The fixed tube 33 is sleeved on the liquid-absorbing cotton tube 31, and the fixed tube 33 is provided with a liquid guide hole 331 connected to the liquid-absorbing cotton tube 31. The liquid-blocking glass fiber tube 34 is sleeved on the fixed tube 33 and covers the liquid inlet hole 27 and the liquid guide hole 331. The inner wall surface of the liquid-blocking glass fiber tube 34 is tightly fitted with the outer wall surface of the fixed tube 33, and the outer wall surface of the liquid-blocking glass fiber tube 34 is tightly fitted with the cavity wall of the atomization chamber 26. The outer wall surface of the liquid-blocking glass fiber tube 34 covers the second turning section 273 , so that the atomized liquid at the second turning section 273 is introduced into the liquid guide hole from the liquid-blocking glass fiber tube 34 .

[0036] The tube wall of the liquid-blocking glass fiber tube 34 is provided with a plurality of liquid seepage holes (not shown in the figure), the liquid inlet hole and the liquid guide hole are both connected to the liquid seepage hole, the cross-sectional area of ​​the liquid seepage hole is smaller than the cross-sectional area of ​​the liquid inlet hole, and the number of the liquid seepage holes is greater than the number of the liquid inlet holes, so that not only the atomized liquid supply is guaranteed to be sufficient, but also when the atomized liquid in the liquid storage chamber vibrates, the atomized liquid cannot flow quickly into the liquid-absorbing cotton tube 31. Specifically, the liquid-blocking glass fiber tube 34 is formed by weaving glass fiber wires, and liquid seepage holes are formed between the glass fiber wires in some areas, and the hole wall of the liquid seepage hole is provided with a plurality of liquid-absorbing fibers, and the free ends of the liquid-absorbing fibers extend into the liquid seepage holes. When the atomized liquid from the liquid inlet hole flows into the liquid guide hole, it is adsorbed and blocked by the liquid-absorbing fibers, so that the rate at which the atomized liquid from the liquid inlet hole flows into the liquid guide hole 331 can be better slowed down.

[0037] The width of the notch of the second turning section 273 facing the liquid-absorbing cotton tube 31 is smaller than the width of the cross section of the second turning section 273. Therefore, while ensuring sufficient atomized liquid, the impact force of the atomized liquid on the liquid-absorbing cotton tube 31 is also reduced. The width of the notch of the first liquid-conducting groove 274 and the second liquid-conducting groove 275 are both smaller than the width of the notch of the second turning section 273 facing the liquid-absorbing cotton tube 31, thereby better avoiding the oversaturation of the atomized liquid. In addition, since the second turning section 273 is located at the inner wall surface of the atomizing chamber 26 and is arranged around the inner wall surface of the atomizing chamber 26, the atomized liquid can be well diffused and flowed evenly.

[0038] The electronic atomization device with balanced liquid supply of the present invention also includes a limit ring 6 and a liquid level guide 7 for preventing the liquid level of the atomized liquid from vibrating. The limit ring 6 is located in the liquid storage chamber 25 and is connected to the liquid storage tube 21. The limit ring 6 is located between the mist outlet 11 and the liquid level guide 7, and is used to prevent the liquid level guide 7 from moving toward the mist outlet 11. The height of the position where the liquid inlet hole 27 and the atomizer core 3 are located is lower than the height of the position where the limit ring 6 is located. The limit ring 6 is located in the middle area of ​​the liquid storage chamber 25. In the initial state, the liquid level of the atomized liquid is higher than the limit ring 6 and the liquid level guide 7. Therefore, when the atomized liquid is more or less, no matter how much the liquid level vibrates, it is not easy to impact the atomizer core 3.

[0039] The liquid level guide 7 is located in the liquid storage chamber 25 and forms a liquid guide gap 70 with the outer wall of the atomizing chamber 26. The liquid level guide 7 is movably sleeved at the outer peripheral surface of the cavity wall of the atomizing chamber 26. When the atomized liquid is large, the atomized liquid can flow downward through the liquid guide gap 70. The liquid level guide 7 includes an up-and-down movement guide ring 71, an abutment ring 72, and a liquid level guide ring 73. The up-and-down movement guide ring 71 is located in the liquid storage chamber 25 and is coaxially arranged with the liquid storage chamber 25. The outer peripheral surface of the up-and-down movement guide ring 71 is tightly fitted with the cavity wall of the liquid storage chamber 25 facing the atomizing chamber 26, and the up-and-down movement guide ring 71 is slidably connected with the cavity wall of the liquid storage chamber 25 facing the atomizing chamber 26. In other words, there is no gap between the outer peripheral surface of the up-and-down movement guide ring 71 and the side of the liquid storage chamber 25 facing the atomizing chamber 26.

[0040] The abutting ring portion 72 is sleeved on the outer peripheral surface of the cavity wall of the atomizing chamber 26, and forms a liquid guide gap 70 with the outer wall of the atomizing chamber 26. The liquid level guide ring portion 73 is sleeved on the outer peripheral surface of the cavity wall of the atomizing chamber 26, the first end of the liquid level guide ring portion 73 is connected to the up-and-down movement guide ring portion 71, the second end of the liquid level guide ring portion 73 is connected to the abutting ring portion 72, and the longitudinal section of the liquid level guide ring portion 73 is trapezoidal. Therefore, when vibration occurs, the atomized liquid can be guided to flow in the direction of the liquid guide gap 70 through the liquid level guide ring portion 73, so that not only the liquid level vibration can be suppressed, but also the area where the atomizing core 3 is located can be prevented from being subjected to excessive pressure.

[0041] The electronic cigarette of the present invention further comprises a push plug 81, a screw rod 82, a fixing ring 83 and a motor 84. The push plug 81 comprises a push tube 811 and a connecting ring 812. The push tube 811 and the connecting ring 812 are both movably sleeved on the outer wall of the atomizing chamber 26. The orthographic projection of the push tube 811 on the plane where the upper end face of the abutting ring portion 72 is located at least partially overlaps with the upper end face of the abutting ring portion 72. The connecting ring 812 is located at one end of the push tube 811 facing away from the liquid surface guide 7 and is connected to the push tube 811. The first end of the screw rod 82 is connected to the connecting ring 812, and the second end of the screw rod 82 is connected to the motor 84. The fixing ring 83 is located in the liquid storage chamber 25 and fixed on the outer wall of the atomizing chamber 26.

[0042] The motor 84 is fixed on the fixing ring 83 and electrically connected to the controller 5, and is used to drive the push plug 81 to move along the axial direction of the liquid storage chamber 25 to control the position height of the liquid level guide 7. When placed vertically and the mist outlet 11 is facing upward, if the liquid level of the smoke liquid is less than the height of the lower end surface of the liquid level guide 7, the motor 84 drives the screw 82 to rotate to drive the push plug 81 to move toward the liquid level guide 7 until the push tube 811 pushes the liquid level guide 7 to a preset position. Therefore, the problem that the atomized liquid is easily vibrated due to external force when the atomized liquid is less is better avoided.

[0043] The electronic cigarette of the present invention also includes a guide rod 85, the first end of which is movably connected to the connecting ring 812, and the second end of the guide rod 85 is connected to the fixing ring 83. The guide rod 85 is located on the first side of the vent pipe 22, and the screw rod 82 is located on the second side of the vent pipe 22, and the first side of the vent pipe 22 and the second side of the vent pipe 22 are arranged relative to each other. The push plug 81 is guided by the guide rod 85, so that the push plug 81 is better prevented from being deflected during movement, the sealing of the push plug 81 to the liquid guide gap 70 is ensured, and the service life is improved. In this embodiment, a control button (not shown in the figure) electrically connected to the controller 5 is movably connected to the housing, and the control button can control the operation of the motor 84.

[0044] In summary, firstly, by sleeve-mounting the liquid-blocking glass fiber tube 34 on the fixed tube 33 and covering the liquid inlet hole 27 and the liquid guide hole 331, the glass fiber structure of the liquid-blocking glass fiber tube 34 can block the flow of the atomized liquid to a certain extent, thereby reducing the fluidity of the atomized liquid, slowing down the speed at which the atomized liquid flows into the liquid-absorbing cotton tube 31, and preventing the user from inhaling the atomized liquid during vibration;

[0045] Secondly, since the liquid inlet hole 27 of the present invention includes a liquid inlet section 271, a first turning section 272 and a second turning section 273, the liquid inlet section 271 is located at the outer wall of the atomizing chamber 26 and is extended along the lateral direction of the liquid storage component 2, the first turning section 272 is located between the outer wall surface and the inner wall surface of the atomizing chamber 26 and is extended along the longitudinal direction of the liquid storage component 2, the first end of the first turning section 272 is connected to the liquid inlet section 271, the second end of the first turning section 272 is connected to the second turning section 273, the second turning section 273 is located at the inner wall surface of the atomizing chamber 26 and is arranged around the inner wall surface of the atomizing chamber 26, and the outer wall surface of the liquid-blocking glass fiber tube 34 covers the second turning section 273, so that the atomized liquid at the second turning section 273 is introduced into the liquid guide hole from the liquid-blocking glass fiber tube 34.

[0046] Therefore, when the atomized liquid in the liquid storage chamber 25 vibrates, the atomized liquid cannot directly enter the liquid absorbing cotton tube 31 through the liquid inlet section 271, but passes through the first turning section 272 to block and move along the longitudinal direction of the liquid storage assembly 2 to reduce the impact force of the atomized liquid, and then guides the atomized liquid to move around the inner wall surface of the atomizing chamber 26 through the second turning section 273 to slowly cover the liquid blocking glass fiber tube 34. Therefore, the problem of the electric heating wire being deformed by the force of the liquid absorbing cotton tube during vibration in the prior art can be avoided.

[0047] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
