All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The electronic atomization device is a novel object different from the traditional cigarette, the electronic atomization device is a device which utilizes electric current to heat related components to evaporate smoke liquid so as to atomize the smoke liquid into steam, and the related components in the electronic atomization device which heat and atomize the smoke liquid are atomizing devices (or atomizers).
The inventor of the application has long-term research and found that when the existing electronic atomization device is used, the atomization device is continuously atomized in the working process, the negative pressure of a cavity for storing the tobacco liquid in the atomization device is continuously increased due to continuous consumption of the tobacco liquid, the blanking of the tobacco liquid is not smooth due to the existence of the negative pressure, and the tobacco liquid is not replaced in time, and burnt smell is generated, so that not only can the product be damaged, but also bad use experience can be brought to a user. In order to solve the above problems, the present application provides some embodiments as follows based on many efforts and hard works made by the inventors.
Referring to fig. 1 to 2, a first embodiment of the atomizing device of the present application mainly includes a cartridge tube 11, a heat generating component 12, and a first seal 13.
Wherein the cartridge tube 11 is formed with a liquid storage chamber 1101 for storing a liquid. The heating component 12 is used for heating and atomizing the smoke liquid from the liquid storage cavity 1101 to form smoke. For example, the liquid storage chamber 1101 and the heating component 12 may be in fluid communication, and the smoke liquid in the liquid storage chamber 1101 may flow onto the heating component 12, and the heating component 12 generates heat to atomize the smoke liquid under the operation of electric current. The first sealing member 13 is disposed between the cartridge tube 11 and the heating element 12 to achieve sealing, and mainly prevents leakage of the smoke flowing from the liquid storage chamber 1101 to the heating element 12. In the present embodiment, an air guide channel 10 is formed between the first seal member 13 and the cartridge tube 11, and air can be guided into the liquid storage chamber 1101 while the first seal member 13 is sealed.
According to the embodiment, the air guide channel is formed between the first sealing piece 13 and the cartridge tube 11, so that air can be smoothly guided into the liquid storage cavity 1101, the pressure in the liquid storage cavity 1101 is balanced, the problems of unsmooth liquid discharge of the liquid storage caused by negative pressure generated by continuous consumption of the liquid storage cavity 1101 are solved, the use experience is improved, and meanwhile, the structure can be simplified.
With continued reference to fig. 1-3, in this embodiment, the cartridge tube 11 includes a first tube wall 111 for enclosing a liquid storage chamber 1101, and the liquid is stored in the liquid storage chamber 1101 enclosed by the first tube wall 111.
Alternatively, the cartridge tube 11 may be provided in a tubular shape, for example, and the specific shape may be provided according to actual requirements. The cartridge tube 11 is provided with the liquid storage chamber 1101, the smoke passage 1102 and the air intake passage 1103 in the axial direction thereof. The liquid storage chamber 1101, the smoke channel 1102 and the air inlet channel 1103 are arranged at intervals, for example, the three are not communicated in the cartridge tube 11.
For example, the cartridge tube 11 may include a first tube wall 111 and a second tube wall 113. The first tube wall 111 encloses a liquid storage chamber 1101. The number of the second pipe walls 113 is 2, for example, the second pipe walls 113 are respectively connected to the outer surface of the first pipe wall 111 in a bent shape, so that an air inlet channel 1103 and a flue gas channel 1102 are respectively defined by the second pipe walls 113 and the first pipe wall 111. In this embodiment, the air inlet channel 1103 is used to guide air outside the atomizing device 1 to the position of the heat generating component 12, and the smoke generated by the heat generating component 12 is carried into the smoke channel 1102 by the airflow generated by the air, so that the smoke channel 1102 guides the smoke to a sucking position, such as a cigarette holder.
For example, the atomizing device 1 is further provided with an air inlet hole 100, which is communicated with the air inlet channel 1103, and air outside the atomizing device 1 can enter the air inlet channel 1103 through the air inlet hole 100.
Specifically, the second pipe wall 113 is located at two sides of the first pipe wall 111, the flue gas channel 1102 and the liquid storage cavity 1101 are separated by the first pipe wall 111, and the air inlet channel 1103 and the liquid storage cavity 1101 are also separated by the first pipe wall 111. Alternatively, the cartridge tube 11 is integrally formed, i.e. the first tube wall 111 and the second tube wall 113 are integrally formed. In this embodiment, the second tube wall 113 may have a greater extension than the first tube wall 111 on the side adjacent to the heat generating component 12.
In this embodiment, the heat generating component 12 may be at least partially located within the first tube wall 111, for example, embedded into the first tube wall 111 from one end of the liquid storage chamber 1101. The first sealing member 13 abuts between the inner surface of the first pipe wall 111 and the outer surface of the heat generating component 12 to seal, wherein the air guide channel 10 is formed between the first sealing member 13 and the inner surface of the first pipe wall 111. For example, a protrusion structure or a groove structure may be provided on an inner surface of the first pipe wall 111 facing the heat generating component 12, and when the first sealing member 13 abuts against the inner surface of the first pipe wall 111, the protrusion structure or the groove structure may enable a gap to exist between the first sealing member 13 and the first pipe wall 111, so as to form the air guide channel 10.
In another embodiment, the heat generating component 12 may be located entirely below the first pipe wall 111, and the liquid storage chamber 1101 and the heat generating component 12 may be communicated by using a first seal 13 with a different shape. In this embodiment, the first sealing member 13 may abut between the first pipe wall 111 and the heat generating component 12 to seal, and the air guide passage 10 may be formed between the first sealing member 13 and the first pipe wall 111 by a protrusion structure or a groove structure.
Referring to fig. 3 to 5, in the present embodiment, a plurality of first ribs 1110 are disposed on an inner surface of the first tube wall 111 adjacent to one end of the heat generating component 12, and the first ribs 1110 protrude from the inner surface of the first tube wall 111. When the first sealing member 13 abuts against the first bead 1110, a gap between the inner surface of the first pipe wall 111 and the first sealing member 13 forms the air guide passage 10. Specifically, the first seal member 13, when abutting against the inner surface of the first pipe wall 111, has a gap at a position adjacent to the first bead 1110 because the first bead 1110 protrudes from the inner surface of the first pipe wall 111, and thus the presence of the gap forms the air guide passage 10.
Alternatively, as shown in fig. 2 and 4, the inner surface of the first tube wall 111 adjacent to one end of the heat generating component 12 is provided with a flange 112 in the circumferential direction. Flange 112 may be used, for example, to stop heat generating component 12 and facilitate a seal between flange 112 and heat generating component 12. The first sealing member 13 is clamped between the flange 112 and the heat generating component 12 to simultaneously contact the flange 112 and the heat generating component 12 for sealing, and further prevents leakage of the smoke liquid in the liquid storage chamber 1101 when flowing onto the heat generating component 12. In this embodiment, the flange 112 is integrally formed on the inner surface of the first tube wall 111. Of course, in other embodiments, the cartridge tube 11 may not be integrally formed, and the flange 112 may be, for example, detachably disposed on the inner surface of the first tube wall 111. The flange 112 has a hole formed around its outer periphery, i.e., the middle portion of the flange 112 is hollow, so that the smoke liquid flows through the hole to the heat generating component 12 in the liquid storage chamber 1101. In the present embodiment, the air guide passage 10 is formed between the first seal 13 and the inner surface of the first tube wall 111 and the flange 112. In this embodiment, air can enter the liquid storage chamber 1101 through the air guide channel 10, so that the pressure difference between the inside and the outside of the liquid storage chamber 1101 can be balanced to some extent.
In the working process of the atomization device 1 of the embodiment, for example, when a user sucks, due to the action of suction pressure, air enters the atomization device 1 from the air inlet hole 100 to form flowing air flow, smoke liquid flows onto the heating component 12 to generate heat and atomize the smoke to form smoke, the smoke enters the smoke channel 1102 along with the flowing of the air flow and finally flows to the sucking position for the user to suck, and due to the fact that the air guide channel 10 can guide the air into the liquid storage cavity 1101, the pressure difference inside and outside the liquid storage cavity 1101 can be balanced to a certain extent, the problem that negative pressure in the liquid storage cavity 1101 is continuously increased due to consumption of the smoke liquid can be solved, accordingly, smoothness of discharging of the smoke liquid is guaranteed, the problem that the existing electronic atomization equipment generates burnt smell can be effectively improved, and the use experience is improved.
Referring to fig. 2, the protruding direction of the flange 112 may alternatively be perpendicular to the inner surface of the first tube wall 111 adjacent to the heat generating component 12 or perpendicular to the axial direction of the cartridge tube 11.
Referring to fig. 4 and 5, the flange 112 may alternatively be provided with second beads 1120 spaced from the surface facing the first seal member 13. The second bead 1120 is provided to protrude from the surface of the flange 112, and when the first seal member 13 abuts against the second bead 1120, a gap is formed between the flange 112 and the first seal member 13 due to the height of the second bead 1120, and a gap is formed at least in the vicinity of the first bead 1110. Because the first sealing member 13 is abutted between the flange 112, the inner surface of the first pipe wall 111 and the heat generating component 12, gaps are formed between the first ribs 1110 and the second ribs 1120, so that the air guide channel 10 can be formed, and air can smoothly enter the liquid storage cavity 1101 through the air guide channel 10.
In this embodiment, the first bead 1110 and the second bead 1120 may be integrally formed from the cartridge tube 11. Meanwhile, the structure of the inner surface of the first tube wall 111 and the flange 112 protruding from the first tube wall 1110 and the second tube wall 1120 can make the ejection of the cartridge tube 11 easier during injection molding.
For example, in the assembly process, the first sealing member 13 is first sleeved on the periphery of the heating element 12, then the heating element 12 sleeved with the first sealing member 13 is embedded into the space surrounded by the first tube wall 111 through one end of the first tube wall 111 adjacent to the heating element 12, and the first sealing member 13 can simultaneously contact the inner surface of the first tube wall 111 and the flange 112, so that more effective sealing can be performed. Because of the height of the first bead 1110, there is also a gap between the first seal 13 and the inner surface of the first pipe wall 111, at least in the vicinity of the first bead 1110. By the cooperation of the first bead 1110 and the second bead 1120, the air guide channel 10 is formed by the gap between the first sealing member 13 and the inner surface of the end of the first tube wall 111 adjacent to the heat generating component 12 and the flange 112, and air can smoothly enter the liquid storage chamber 1101 through the air guide channel 10. In this embodiment, by providing the first ribs 1110 and the second ribs 1120, the air guide channel 10 can be effectively formed, so that air can smoothly enter the liquid storage cavity 1101, and the pressure in the liquid storage cavity 1101 is balanced to avoid the problems of unsmooth liquid discharge caused by negative pressure.
With continued reference to fig. 4 and 5, alternatively, one end of the second bead 1120 extends to the outer edge of the flange 112, and the other end of the second bead 1120 extends to the junction of the flange 112 and the first tube wall 111, e.g., the second bead 1120 may extend substantially linearly. One end of the first rib 1110 is connected to the second rib 1120, the other end of the first rib 1110 extends to an edge of the first tube wall 111 near one end of the heating element 12, and the first rib 1110 may also extend substantially linearly. In this embodiment, the second ribs 1120 and the first ribs 1110 are connected together, so that the air guide channel 10 is formed to be smoother when guiding air. Of course, in other embodiments, the line types of the second bead 1120 and the first bead 1110 are not limited, and may be curves, arcs, etc. In other embodiments, the second bead 1120 and the first bead 1110 may be spaced apart, such as where the second bead 1120 is offset from the first bead 1110 at the junction of the flange 112 and the first tube wall 111.
With continued reference to fig. 4, the number of the first ribs 1110 is optionally 2-8, and the first ribs 1110 are disposed on opposite sides of the inner surface of the first pipe wall 111 and are disposed at intervals between the first ribs 1110 on the same side. For example, the first ribs 1110 are 4, and are disposed on two sides of the inner surface of the first pipe wall 111, 2 ribs are disposed on each side, and 2 ribs on the same side are disposed at intervals. The interval between two adjacent first beads 1110 located at the same side, for example, 1-3mm, may be designed according to practical requirements.
With continued reference to FIG. 4, the second ribs 1120 may optionally be 2-8 in number, and correspondingly disposed on opposite sides of the surface of the flange 112 facing the heat generating component 12. It is possible to provide a part of the second beads 1120 on one side and another part of the second beads 1120 on the opposite side, for example, when the number of the second beads 1120 is 4, 2 are provided on one side and the other 2 are provided on the other side. The second ribs 1120 on each side are spaced apart or arranged in a spaced apart relationship. The distance between two adjacent second ribs 1120 located on the same side is 1-3mm, for example, and can be designed according to practical requirements. The number of the first ribs 1110 and the second ribs 1120 may be the same or different, for example, the number of the first ribs 1110 and the second ribs 1120 is the same as 4, and the 4 first ribs 1110 are respectively connected with the 4 second ribs 1120 correspondingly.
In other embodiments, the second bead 1120 may be disposed on the surface of the flange 112 facing the first seal member 13 along the circumferential direction formed by the second bead 1120, where the extension length of the second bead 1120 is smaller than the circumference of the outer edge of the flange 112, so as to avoid the situation that the second bead 1120 forms a closed loop on the surface of the flange 112 and cannot conduct air. That is, in the present embodiment, the line type and the extending direction of the second bead 1120 and the first bead 1110 may not be limited, but when the second bead 1120 is circumferentially provided on the surface of the flange 112, the extending length of the second bead 1120 is smaller than the circumference of the outer edge of the flange 112. Similarly, when the first bead 1110 is circumferentially disposed on the inner surface of the first pipe wall 111, the extension length of the first bead 1110 is smaller than the circumference of the inner surface of the first pipe wall 111 in a cross section perpendicular to the axial direction thereof.
Alternatively, in this embodiment, the height of the first ribs 1110 protruding from the inner surface of the first tube wall 111 toward the heat generating component 12 is 0.05mm to 0.2mm, alternatively 0.07mm to 0.15mm, and further alternatively 1mm to 0.12mm. Alternatively, the width of the first bead 1110 in the direction perpendicular to the height thereof is 0.07mm to 0.2mm, alternatively 0.09mm to 0.12mm. In the present embodiment, when the first bead 1110 extends substantially linearly, the width direction of the first bead 1110 is substantially perpendicular to the extending direction and the height direction thereof. Optionally, the height of the surface of the second bead 1120 protruding from the flange 112 facing the heat generating component 12 is 0.05mm-0.2mm, optionally 0.07mm-0.15mm, and optionally 0.1mm-0.12mm. Alternatively, the width of the second bead 1120 in the direction perpendicular to the height thereof is 0.07mm to 0.2mm, alternatively 0.09mm to 0.12mm. In the present embodiment, when the second bead 1120 extends substantially linearly, the width direction of the second bead 1120 is substantially perpendicular to the extending direction and the height direction thereof. After long-time experiments, the inventors found that when the heights of the first ribs 1110 and the second ribs 1120 are both 0.05mm-0.2mm and the widths are both 0.05mm-0.2mm, the formed air guide channel 10 can better guide air, and meanwhile, smoke liquid can be prevented from leaking from the air guide channel 10.
In other embodiments, the first bead 1110 may be disposed on a surface of the first seal 13 facing the first tube wall 111. Further, the second bead 1120 may be provided on the surface of the first seal member 13 facing the flange 112. In other embodiments, the first bead 1110 may be disposed on the surface of the first seal 13 facing the first tube wall 111, and the second bead 1120 may be disposed on the surface of the flange 112 facing the first seal 13. Alternatively, the first bead 1110 may be disposed on the inner surface of the first pipe wall 111, and the second bead 1120 may be disposed on the surface of the first seal member 13 facing the flange 112, and when the first seal member 13 abuts the first pipe wall 111 and the flange 113, the gap near the first bead 1110 and the gap near the second bead 1120 communicate to form the air guide channel 10.
With continued reference to fig. 2-4, optionally, the heat generating component 12 includes a porous ceramic liquid conductor 121 and a heat generating element 122. In the present embodiment, for example, the porous ceramic liquid guide 121 is made of a porous ceramic material or the like, for example, a ceramic material sintered at a high temperature from an aggregate, a binder, a pore-forming agent, and the like, and has a large number of porous structures communicating with each other and with the surface of the material. The porous ceramic material has the excellent performances of high porosity, stable chemical property, large specific surface area, small volume density, low thermal conductivity, high temperature resistance, corrosion resistance and the like. The air guide channel 10 is arranged, so that the problem that ventilation cannot be effectively performed under the condition that negative pressure is generated in the liquid storage cavity 1101 caused by smoke absorption of a user is generated due to the bent porous structure of the porous ceramic liquid guide body 121 can be further avoided, the problem that the smoke smell is caused due to unsmooth liquid discharge of the porous ceramic liquid guide body 121 due to the fact that ventilation cannot be performed due to the porous structure is also avoided, the atomization efficiency of the atomization device 1 is improved, and the use experience is improved.
With continued reference to fig. 2 and 3, a liquid guiding groove 1210 is formed on a side of the porous ceramic liquid guiding body 121 facing the liquid storage chamber 1101, that is, the liquid guiding groove 1210 is formed by recessing a side (which may be referred to as a top surface 121 a) of the porous ceramic liquid guiding body 121 facing the liquid storage chamber 1101 into the porous ceramic liquid guiding body 121.
