Description

Technical Field

[0001] The present invention relates to the technical field of atomizers, and more specifically, the present invention relates to an anti-clogging atomizer. Background Art

[0002] Electronic atomization devices emit smoke for users by heating atomization liquid. Existing electronic atomization devices generally include a battery rod and an atomizer. There is a battery in the battery rod to supply power to the atomizer. The atomizer includes a heating unit. The heating unit includes a liquid guide for adsorbing and conducting the atomization liquid. When the heating unit is powered on, the solution to be atomized can be atomized into a mist for the user to inhale. Electronic atomization devices are specifically applied to electronic cigarettes, medical drug atomization devices, etc. The atomization liquid includes medical liquid, e-cigarette liquid, etc. Its basic function is to provide heating and atomization functions, and convert the atomization liquid or medical liquid stored in the atomizer into mist, aerosol, vapor, etc.

[0003] In existing electronic atomization devices, the material of the liquid guide in the atomizer includes porous ceramic materials. The atomization core made of existing porous ceramic materials is generally made into a tubular or square shape. Its liquid absorption surface is located on the outer wall, and the atomization surface is located in the central through hole of the atomization core. The central through hole of the atomization core serves as both the atomization surface and the air flow channel, and the air flow also flows out through this central through hole. Such an atomization core is suitable for atomization liquids with low viscosity and good fluidity. When the viscosity of the atomization liquid used is relatively high, after the atomizer stops working, the atomization liquid slowly seeps out from the atomization surface and is easily condensed on the inner wall of the central through hole of the atomization core, reducing the flow area of the central through hole and even causing blockage. When the atomizer works next time, the air flow cannot be smoothly sucked out from the central through hole or the air flow channel, resulting in an extremely bad user experience for users. Summary of the Invention

[0004] The purpose of the present invention is to provide an anti-clogging atomizer that can avoid blockage of the air flow channel.

First and second vertical grooves are respectively provided on both sides of the outer side wall of the middle and lower parts of the upper atomization seat at the two sides of the transverse through-hole of the upper seat. Both the first and second vertical grooves communicate the transverse through-hole of the upper seat with the atomization cavity.

[0006] Preferably, the cavity between the atomization outer tube, the ventilation tube, the mouthpiece seat, and the upper atomization seat is set as a liquid storage cavity for storing atomization liquid. Liquid through-holes are also provided on both sides of the upper seat central hole of the upper atomization seat. The liquid through-holes communicate the liquid storage cavity with the upper surface of the porous body atomization core.

[0007] Preferably, an atomization core sealing sleeve is provided between the outer side wall of the porous body atomization core and the inner side wall of the upper seat cavity.

[0008] Preferably, the porous body atomization core includes a porous body and a heating resistor. A liquid storage groove is provided downward on the upper end surface of the porous body. The heating resistor is arranged on the lower end surface of the porous body. Electrode pins are respectively connected to both ends of the heating resistor.

[0009] Preferably, the outer side wall of the upper part of the mouthpiece seat is sleeved with the inner side wall of the lower end of the mouthpiece. The outer side wall of the lower part of the mouthpiece seat is sleeved with the inner side wall of the upper end of the atomization outer tube. A mouthpiece seat sealing ring is also provided on the lower wall of the mouthpiece seat. The mouthpiece sealing ring seals the gaps between the atomization outer tube and the mouthpiece seat, and between the mouthpiece seat and the ventilation tube at the same time.

[0010] Preferably, a retaining ring is also provided on the upper end surface of the mouthpiece seat. A ventilation tube annular groove is provided on the outer side wall of the upper part of the ventilation tube. The retaining ring is clamped in the ventilation tube annular groove.

[0011] Preferably, the outer side wall of the upper part of the atomizing upper seat is sleeved on the inner side wall of the lower end of the atomizing outer tube, and the outer side wall of the lower part of the atomizing upper seat is sleeved on the inner side wall of the upper end of the connecting seat.

[0012] Preferably, the atomizing lower seat includes a bracket sleeved on the inner side wall of the lower part of the atomizing upper seat and supporting the porous atomizing core. The atomizing cavity is arranged in the middle of the bracket. A convex column fitting into the first vertical groove is arranged upward at the upper end of one side of the bracket. An induction air groove is axially arranged on the outer side wall of the convex column, and the induction air groove communicates the transverse through hole of the upper seat with the atomizing cavity.

[0013] Preferably, the lower part of the connecting seat is provided with a connecting pipe with a reduced outer diameter. A connecting thread is arranged on the outer side wall of the connecting pipe for threaded connection with the battery rod. A tubular electrode is sleeved inside the connecting pipe. An insulating ring is arranged between the tubular electrode and the connecting pipe. The upper end of the tubular electrode extends into the upper middle part of the atomizing cavity. The upper end surface of the tubular electrode is closed and a second air inlet is arranged on the upper side surface. A flange is arranged at the bottom end of the tubular electrode.

[0014] Preferably, the outer tube is made of a transparent material so as to observe the remaining amount of the atomizing liquid in the liquid storage cavity. The porous atomizing core includes a porous body made of porous ceramic material.

[0015] The beneficial effect of the atomizer with anti-blocking function of the present invention is as follows: The atomizer is provided with a porous atomizing core and an air vent pipe. The atomizing cavity is arranged at the lower part of the porous atomizing core. The porous atomizing core is not provided with a central through hole in the middle. A liquid storage groove is arranged on it, and the lower surface is set as an atomizing surface. The atomizing liquid seeps downward from the liquid storage groove to the lower surface and is atomized in the atomizing cavity. The atomized misty air flow flows upward through the atomizing lower seat, the second vertical groove of the atomizing upper seat, the transverse through hole of the upper seat, the air vent pipe, and the nozzle through hole and then flows out. With this structure, when the atomizer uses an atomizing liquid with a relatively high viscosity, even if the atomizing liquid slowly seeps out from the atomizing surface and causes condensation, it will not block the air vent pipe; in addition, the upper end of the tubular electrode extends into the upper middle part of the atomizing cavity. The upper end surface of the tubular electrode is closed and a second air inlet is arranged on the upper side surface. The atomizing liquid dripping during atomization will not flow into the electrode through hole in the electrode tube, thus avoiding the phenomenon that the air flow channel is easily blocked, and greatly improving the user experience.

The cavity between the atomization outer tube 3, the ventilation tube 4, the mouthpiece seat 2, and the upper atomization seat 5 is set as a liquid storage cavity 9 for storing atomization liquid. In this embodiment, the atomization outer tube 3 is made of a transparent material to observe the remaining amount of atomization liquid in the liquid storage cavity 9.

[0048] As Figures 2 - 8 shown, the outer side wall of the upper part of the mouthpiece seat 2 is sleeved with the inner side wall of the lower part of the mouthpiece through hole 10, and a mouthpiece seat sealing ring 22 is sleeved on the outer side wall of the lower part of the mouthpiece seat 2. The mouthpiece seat sealing ring 22 seals the gaps between the atomization outer tube 3 and the mouthpiece seat 2, and between the mouthpiece seat 2 and the ventilation tube 4 at the same time.

[0049] As Figures 9 - 11 shown, a retaining ring 21 is further provided on the upper end surface of the mouthpiece seat 2. In this embodiment, it is a plum blossom retaining ring. A ventilation tube annular groove 41 is provided on the outer side wall of the upper part of the ventilation tube 4, and the retaining ring 21 is clamped in the ventilation tube annular groove 41, so that the ventilation tube 4 can be axially fixed.

[0050] As Figures 2 - 5 , Figures 12 - 15 shown, a transverse through hole 51 is provided in the middle of the upper atomization seat 5 and is communicated with the upper seat central hole 50. First vertical grooves 52 and second vertical grooves 53 are respectively provided on both sides of the outer side wall of the middle and lower parts of the upper atomization seat 5 located on both sides of the transverse through hole 51 to communicate the transverse through hole 51 with the atomization cavity 60.

[0051] An upper seat cavity 55 is provided upward on the lower end surface of the upper atomization seat 5, and the porous atomization core 7 is arranged inside the upper seat cavity 55. Liquid through holes 54 are further provided on both sides of the upper seat central hole 50 of the upper atomization seat 5. The liquid through holes 54 communicate the liquid storage cavity 9 and the upper surface of the porous atomization core 7, and can drain the atomization liquid in the liquid storage cavity 9 to the upper surface of the porous atomization core 7.

[0052] As Figure 2, Figure 3 As shown in the figure, a shoulder 56 is provided on the outer side of the upper part of the atomizing upper seat 5. The outer side wall of the upper part of the atomizing upper seat 5, that is, the part above the shoulder 56, is sleeved on the inner side wall of the lower part of the atomizing outer tube 3. A first sealing ring groove 57 is provided on the outer side wall above the shoulder 56, and a first sealing ring 570 is provided in the first sealing ring groove 57 to seal the gap between the atomizing outer tube 3 and the atomizing upper seat 5. The outer side wall of the middle part of the atomizing upper seat 5, that is, the part below the shoulder 56, is sleeved on the inner wall of the upper part of the connecting seat 8. A second sealing ring groove 58 is provided on the outer side wall below the shoulder 56, and a second sealing ring 580 is provided in the second sealing ring groove 58 to seal the gap between the connecting seat 8 and the atomizing upper seat 5.

[0053] As Figures 2 - 5 , Figures 16 - 19 As shown in the figure, an atomizing core sealing sleeve 70 is provided between the outer side wall of the porous atomizing core 7 and the inner side wall of the upper seat cavity 55.

[0054] The porous atomizing core 7 includes a porous body 71 and a heating resistor 72. A liquid storage groove 710 is provided downward on the upper end surface of the porous body 71. The heating resistor 72 is provided on the lower end surface of the porous body 7, and electrode pins 73 are respectively connected to both ends of the heating resistor 72. In this embodiment, the porous body 71 is made of porous ceramic material, and the porous atomizing core 7 is a porous ceramic atomizing core. The porous body 71 has a microporous structure, which can make the atomizing liquid in the liquid storage groove 710 penetrate and conduct to the lower end surface of the porous body 71 for the heating resistor 72 to heat and atomize.

[0055] The porous atomizing core 7 is not provided with a central through hole in the middle. A liquid storage groove 710 is provided on it, and the lower surface is set as an atomizing surface. The atomizing liquid penetrates downward from the liquid storage groove 710 to the lower surface and is atomized in the atomizing cavity. The atomized misty air flow flows upward through the atomizing lower seat 6, the second vertical groove 53 of the atomizing upper seat, the upper seat transverse through hole 51, the ventilation pipe 4, and the nozzle through hole 10. This structure makes it possible that when using an atomizing liquid with a relatively high viscosity, even if the atomizing liquid slowly oozes out from the atomizing surface and causes condensation, it will not block the ventilation pipe or the air flow channel.

[0056] As Figures 2 - 5 , Figures 20 - 24As shown, the lower atomizing base 6 includes a bracket 61 sleeved on the inner side wall of the lower part of the upper atomizing base 5 and supporting the porous atomizing core 7. A notch is provided at the lower part of the bracket 61 so that the atomizing cavity communicates upward with the first vertical groove 52 and the second vertical groove 53. The atomizing cavity 60 is arranged in the middle of the bracket 61 and is enclosed by the connecting seat 8. At the upper end of one side of the bracket 61, a convex column 62 is provided upward and fitted into the first vertical groove 52. An induction air groove 620 is axially provided on the outer side wall of the convex column 62. Both the induction air groove 620 and the second vertical groove 53 communicate with the atomizing cavity 60. The bottom of the lower atomizing base 6 is arranged at the inner bottom of the connecting seat 8. A lower seat through hole 63 is provided at the bottom of the lower atomizing base 6, and the lower seat through hole 63 is used for the following tubular electrode 80 to extend upward into the atomizing cavity 60.

[0057] As Figures 2 - 5 , Figure 25 shown, the lower part of the connecting seat 8 is a connecting pipe 81 with a reduced outer diameter. A connecting thread is provided on the outer side wall of the connecting pipe 81 for threaded connection with the battery rod. A first air inlet hole 82 is provided on the outer side wall of the lower part of the connecting seat 8 and communicates with the atomizing cavity 60.

[0058] A tubular electrode 80 is sleeved inside the connecting pipe 81. The tubular electrode 80 is used to connect one of the electrode pins 73, and the connecting seat 8 connects the other electrode pin 73. An electrode through hole 801 is provided inside the tubular electrode. An insulating ring 83 is provided between the tubular electrode 80 and the connecting pipe 81. The upper end of the tubular electrode 80 extends into the upper middle part of the atomizing cavity 60 and is at a certain distance from the bottom of the atomizing cavity 60. Even if a little atomizing liquid accumulates at the bottom of the atomizing cavity 60, it will not overflow into the electrode through hole 801. The upper end surface of the tubular electrode 80 is closed and a second air inlet hole 802 is provided on the upper side surface of the tubular electrode 80. The tubular electrode 80 is provided with an electrode through hole leading from the bottom to the second air inlet hole 802. The upper end surface of the tubular electrode 80 is closed, which can prevent the atomizing liquid droplets leaking from the porous atomizing core 7 in the upper part of the atomizing cavity from dropping into the electrode through hole 801 of the tubular electrode 80. And the thicker atomizing liquid is likely to cause blockage of the electrode through hole 801, making the airflow sensor unable to sense the inhalation airflow. The second air inlet hole 802 is provided on the upper side surface of the tubular electrode 80 and is at a relatively high distance from the bottom of the atomizing cavity 60, avoiding the atomizing liquid dripping to the bottom of the atomizing cavity 60 from flowing into the electrode through hole 801 inside the tubular electrode 80 through the second air inlet hole 802. The thicker atomizing liquid is likely to cause blockage of the electrode through hole 801. A flange 803 is provided at the bottom end of the tubular electrode 80 and a convex ring 804 is provided on the outer side wall of the tubular electrode. The flange 803 and the convex ring 804 are used to clamp the insulating ring 83 and fix it inside the connecting pipe 81.

[0059] As Figures 2 - 5As shown, for the anti-clogging atomizer of this embodiment, when it works, due to the suction of the mouthpiece 1, external gas flows into the atomization chamber 60 from the first air inlet hole 82. At this time, the atomization liquid flows downward from the liquid storage chamber 9 through the liquid through hole 54 to the liquid storage groove 710 of the porous atomization core 7, and then penetrates to the atomization surface at the bottom of the porous atomization core 7, where it is heated and atomized into vapor by the heating resistor 72 and dissipated in the atomization chamber 60. The vapor flows to one side along with the entering external gas through the support gap of the lower atomization seat, the second vertical groove 53 of the upper atomization seat, the upper seat transverse through hole 51, the upper seat central hole 50, the air pipe 4, and the mouthpiece through hole 10 and is then sucked into the user's mouth. When the user sucks at the mouthpiece 1, a negative pressure is generated in the air pipe 4 at the same time, and the air flow flows upward from the bottom of the electrode through hole 801, passes through the second air inlet hole 802, the atomization chamber 60, the induction air groove 620, and the upper seat transverse through hole 51 and converges into the air pipe 4, so that the air flow sensor provided in the battery rod can be triggered to start the heating resistor 72 to work. The continuous arrows in the figure indicate the direction of the air flow when the atomizer works.

[0060] The above description only relates to the preferred embodiments of the present invention, and the above specific embodiments do not limit the present invention. Within the scope of the technical idea of the present invention, various deformations and modifications can occur. Any retouching, modification or equivalent replacement made by those of ordinary skill in the art based on the above description shall fall within the scope protected by the present invention.
