Description

Atomizer with leakage guide channel TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic cigarette atomizers, and more particularly to an atomizer with a leakage guide channel. BACKGROUND

[0002] The existing electronic cigarette is an electronic atomization device, which generally comprises a battery assembly and an atomizer. The battery assembly is internally provided with a battery, and the battery supplies power to the atomizer. The atomizer comprises an atomizing core mounted on an atomizing support. The atomizing core comprises a liquid guide and a heating body. When the heating body is powered, it can heat and evaporate the solution to be atomized, i.e. atomizing liquid or electronic cigarette liquid, into steam, electronic cigarette smoke or aerosol. The atomizing liquid can be stored in a liquid storage cavity provided in the electronic cigarette atomizer.

[0003] The existing electronic cigarette atomizer on the market needs to be transported to the sales location after production, and is often transported by air. When the electronic cigarette atomizer is transported at high altitude, the atomizing liquid or liquid stored in the liquid storage cavity is easily leaked to the atomizing cavity through the gap between the atomizing core and the support due to changes in external pressure in the non-working state. Since the atomizing cavity is directly connected with the smoke discharge channel, the leaked liquid can further leak to the smoke discharge channel, which is easily directly inhaled into the mouth when the user smokes, resulting in poor taste and poor smoking experience.

[0032] The present application will be described in detail below through specific embodiments. Embodiment 1

[0033] As shown in Figs. 1 and 2, the atomizer with liquid leakage guide channel of the present application comprises a hollow shell 1, one end of the shell 1 is provided with a suction nozzle 11, and the other end away from the suction nozzle 11 is provided with a completely open opening 10. The suction nozzle 11 is provided with a suction port 111 extending inward, i.e. toward the opening 10, and is connected with a smoke outlet pipe 112. The shell 1 is sequentially provided with an atomization bracket 2, a bracket sealing sleeve 3 and a base 4 from top to bottom, the bottom of the atomization bracket 2 is further provided with an atomization core 6, the base 4 is provided in the bottom of the shell 1, i.e. on the inner wall of the opening 10, and the bottom of the shell 1, i.e. one end at the opening 10, is further provided with a bottom shell 5.

[0034] As shown in Fig. 3, the atomization core 6 comprises a liquid guide layer 61 and a ceramic heating element 62 stacked together, the bottom surface of the ceramic heating element 62 is provided as an atomization surface 620, and the upper surface of the atomization core opposite to the atomization surface 620 is provided as a liquid inlet surface, which is in communication with the liquid inlet channel 230. The atomization surface 620 is provided with a heating resistor layer 621 and an electrode layer 622, the electrode layer 622 is provided on both sides of the heating resistor layer 621 and is electrically connected with each other. In this embodiment, the liquid guide layer 61 is composed of a liquid-conducting cotton material. The base body of the ceramic heating element 62 is composed of a liquid-conducting porous ceramic material, and the atomization surface 620 is provided on the bottom surface of the base body of the ceramic heating element 62.

[0035] As shown in Figs. 2 and 4-8, the bottom of the atomization bracket 2 is provided with a smoke outlet through hole 25, an atomization core accommodating groove 26 and a liquid leakage collection groove 27 in parallel, and the atomization core 6 is provided in the atomization core accommodating groove 26.

[0036] The atomization bracket 2 is provided with a transverse partition plate 21, the edge of the transverse partition plate 21 is consistent with the size and shape of the inner wall cross section of the shell 1, and the edge of the transverse partition plate 21 is sleeved on the inner wall of the shell 1 at the end close to the opening 10.

[0037] The upper part of the atomization support 2, i.e., one side of the transverse plate 21, is provided with a tubular body 22 connected with the smoke outlet pipe 112. The tubular body 22 is provided with a smoke outlet passage 220 penetrating therethrough, which is in communication with the smoke outlet pipe 112. The tubular body 22 is further provided with a liquid inlet passage 230, which is provided with a liquid inlet opening 23 on the side wall of the tubular body 22. The liquid inlet passage 230 is isolated from the smoke outlet passage 220. In the embodiment, the connection between the smoke outlet pipe 112 and the tubular body 22 is further provided with a sealing seat 9, which is used to seal the gap between the connection of the smoke outlet pipe 112 and the tubular body 22, so as to avoid the atomization liquid in the liquid storage cavity 100 from leaking into the smoke outlet pipe 112, and prevent the user from inhaling the atomization liquid in the liquid storage cavity 100 when smoking.

[0038] As shown in FIG. 1, the upper part of the atomization support 2, i.e., the upper part of the transverse plate 21, is provided with a liquid storage cavity 100 formed by the cavity between the inner wall of the shell 1, the outer wall of the smoke outlet pipe 112 and the transverse plate 21.

[0039] As shown in FIG. 1 and FIG. 5, in the embodiment, the liquid inlet opening 23 is arranged at the joint of the transverse plate 21 and the tubular body 22. The surface of the upper part of the atomization support 2, i.e., the upper surface of the transverse plate 21, is provided with a slight V-shaped inclined surface on both sides of the liquid inlet opening 23. In this way, when the amount of atomization liquid in the liquid storage cavity 100 is small, the atomization liquid can also flow to the lowest point, i.e., the liquid inlet opening 23, through the inclined surface, so as to ensure that the atomization liquid can be consumed as much as possible.

[0040] As shown in FIG. 4-FIG. 8, the bottom of the atomization support 2, i.e., one side of the lower surface of the transverse plate 21, is provided with a surrounding wall 24. The surrounding wall 24 is provided with smoke outlet holes 25 on one side relative to the tubular body 22. The smoke outlet holes 25 are in communication with the smoke outlet passage 220. The hole wall of the smoke outlet holes 25 close to the atomization core 6 is lower than the hole wall of the remaining part and is flush with the surface of the atomization core 6, thereby forming a smoke discharge gap 250. When the atomization core 6 works, the vapor or electronic cigarette smoke formed by the evaporation of the surface of the atomization core 6 can more easily pass through the smoke discharge gap 250 into the smoke outlet holes 25, then flow through the smoke outlet passage 220, the smoke outlet pipe 112 and the suction port 111 in sequence, and finally be inhaled into the user's mouth. In the embodiment, the smoke outlet holes 25 are two, which are respectively arranged on both sides of the atomization core 6. The two smoke outlet holes 25 are extended upward to converge and communicate with the smoke outlet passage 220.

[0041] The surrounding wall 24 is provided with an atomization core accommodating groove 26 close to the smoke outlet holes 25. The atomization core 6 is installed in the atomization core accommodating groove 26. The bottom of the atomization core accommodating groove 26 is in communication with the liquid inlet passage 23. The atomization core 6 and the bottom of the atomization core accommodating groove 26 are further provided with a ring-shaped sealing gasket 8. The ring-shaped sealing gasket 8 can seal the gap between the bottom of the atomization core 6 and the bottom of the atomization core accommodating groove 26, so as to ensure that the atomization liquid entering the liquid inlet passage 23 can be fully permeated into the atomization core 6, and prevent the atomization liquid from leaking around the liquid inlet surface of the atomization core 6.

[0042] The liquid leakage collection groove 27 is further provided in the surrounding wall 24, and the first liquid absorption body 7 is installed in the liquid leakage collection groove 27. In the embodiment, the first liquid absorption body 7 is composed of a block-shaped liquid-absorbable cotton material.

[0043] A liquid leakage flow guide channel 28 is provided between the side surface of the atomization core containing groove 26 and the side surface of the liquid leakage collection groove 27. From the perspective of the inverted atomizer, the bottom of the liquid leakage flow guide channel 28 is lower than the atomization surface 620 of the atomization core 6. The liquid leakage flow guide channel 28 can guide the atomization liquid leaked from the atomization core 6 to the liquid leakage collection groove 27 and be absorbed and stored by the first liquid absorption body 7.

[0044] When the electronic cigarette atomizer is transported at high altitude, the atomization liquid or smoke liquid stored in the liquid storage cavity is easily flowed from the liquid inlet surface to the atomization surface of the atomization core, and then leaked to the atomization cavity through the gap between the atomization core and the atomization support due to the change of external pressure, even if it is in a non-working state. The electronic cigarette atomizer of the present application is provided with the structure of the liquid leakage flow guide channel 28 and the liquid leakage collection groove 27, so that the atomization liquid leaked from the atomization core 6 can be guided to the liquid leakage collection groove 27 through the liquid leakage flow guide channel 28 and stored before reaching the atomization surface 620, avoiding the atomization liquid flowing to the atomization surface 620 and further flowing to the smoke outlet through hole 25. Therefore, the electronic cigarette atomizer has the effect of preventing liquid leakage, avoiding the leaked smoke liquid from being directly inhaled into the user's mouth through the smoke outlet channel, and preventing the user's taste and smoking experience from being reduced.

[0045] In addition, the liquid leakage flow guide channel 28 can be filled with a liquid absorption strip (not shown in the figure), which is connected with the first liquid absorption body 7. The atomization liquid leaked from the atomization core 6 is more easily absorbed by the liquid absorption strip and guided to the first liquid absorption body 7 for absorption and storage through the liquid absorption strip, which can avoid the leakage of the atomization liquid flowing in the liquid leakage flow guide channel 28 and has a better effect of preventing liquid leakage. In the embodiment, the liquid absorption strip is composed of a strip-shaped liquid-absorbable cotton material.

[0046] As shown in FIG. 9 and FIG. 10, the bracket sealing sleeve 3 is connected to the bottom of the atomization bracket 2, i.e. to one side of the surrounding wall 24 of the horizontal partition plate. The bracket sealing sleeve 3 seals upwardly the liquid leakage collection groove 27, so that the liquid leakage collection groove 27 forms a relatively sealed cavity, preventing the atomization liquid collected and stored by the first liquid absorbing body 7 in the liquid leakage collection groove 27 from leaking again. The bracket sealing sleeve 3 simultaneously encloses the bottom space of the smoke outlet through hole 25 and the atomization core accommodating groove 26 upwardly and forms an atomization cavity 200, in which the surface of the atomization core 6 can form vapor or electronic cigarette smoke after being heated and evaporated. In the embodiment, the bracket sealing sleeve 3 is made of silica gel material, which has better high-temperature resistance and sealing performance. In order to better form the atomization cavity 200, the bottom wall of the bracket sealing sleeve 3 at the bottom of the smoke outlet through hole 25 and the atomization core accommodating groove 26 is downwardly protruded as an arc surface structure 34, so as to constitute the atomization cavity 200 with a larger space.

[0047] The side wall of the bracket sealing sleeve 3 is sealed to the inner wall of the shell 1, i.e. the edge of the bracket sealing sleeve 3 is consistent with the edge of the horizontal partition plate 21 and the sealing sleeve is sealed to the inner wall of the shell 1 near the opening 10, so as to prevent the atomization liquid stored in the liquid storage cavity 100 from leaking through the gap between the side wall of the bracket sealing sleeve 3 and the inner wall of the shell 1.

[0048] The bracket sealing sleeve 3 is further provided with a groove 30 for sealing and accommodating the surrounding wall 24, the surrounding wall 24 of the atomization bracket is tightly sealed to the side wall of the groove 30, and the bottom of the groove 30 is provided with an electrode through hole 31 and an air inlet through hole 32 corresponding to the position of the atomization core 6.

[0049] In order to firmly connect the bracket sealing sleeve 3 and the atomization bracket 2 without loosening, the bottom of the atomization bracket 2, i.e. the lower surface of the horizontal partition plate 21, is further provided with a fixing column 29, and the bracket sealing sleeve 3 is further provided with a fixing hole 33 corresponding to the fixing column 29, and the fixing column 29 is inserted into the fixing hole 33. In the embodiment, the fixing column 29 and the fixing hole 33 are respectively provided with four pairs, which are arranged at the four corner portions of the bracket sealing sleeve 3 and the atomization bracket 2.

[0050] As shown in FIG. 1, FIG. 2 and FIG. 11, the base 4 is connected with the bottom of the support sealing sleeve 3, and a concave cavity 40 is arranged on the base 4 at the bottom of the support sealing sleeve 3. A second liquid absorbing body 41 is arranged in the concave cavity 40. In special cases, the atomized liquid leaked from the atomizing core 6 can further leak into the concave cavity 40 of the base 4 from the electrode through hole 32 of the support sealing sleeve 3 and the sealing sleeve air inlet through hole 31. In addition, when the atomizer works, the atomizing core 6 can carry a part of the liquid droplets which are not completely atomized when generating the electronic cigarette smoke in the atomizing cavity, and the liquid droplets can condense on the inner wall of the atomizing cavity or the smoke exhaust channel when the user pauses smoking. These atomized liquids can further leak into the concave cavity 40 of the base 4. The concave cavity 40 can collect the leaked atomized liquid, and the second liquid absorbing body 41 can better absorb and store the above-mentioned leaked atomized liquid, so as to avoid the leaked atomized liquid from being inhaled into the user's mouth or leaking from the bottom of the atomizer into the battery assembly connected with the atomizer, causing the corrosion of the circuit in the battery assembly. In the embodiment, the second liquid absorbing body 41 is also composed of a block-shaped liquid-absorbing cotton material.

[0051] The base 4 is provided with a base air inlet through hole 41 and an electrode column 42 for electrical connection with an external power source. The electrode column 42 abuts against the electrode layer 622 of the ceramic heating element after penetrating through the electrode through hole 32 of the support sealing sleeve 3. The base air inlet through hole 41 is in communication with the sealing sleeve air inlet through hole 31.

[0052] The transverse partition plate 21 of the atomizing support and the two sides of the support sealing sleeve 3 are respectively provided with through liquid injection through holes 101, and the base 4 is provided with plungers 43 corresponding to the liquid injection through holes 101 for plugging the liquid injection through holes 101. In the assembly production, the atomized liquid or electronic cigarette smoke liquid can be filled into the liquid storage cavity 100 through the liquid injection through holes 101, and then the plungers 43 are plugged into the liquid injection through holes 101 by installing the base 4.

[0053] As shown in FIG. 2, the bottom shell 5 is sleeved on the bottom outer wall of the shell 1 from bottom to top, and can support the base 4 upward. The end face of the bottom shell 5 is provided with a notch 50 for exposing the electrode point (not shown in the figure) on the base 4 and the base air inlet through hole 41. In the embodiment, the bottom shell 5 is made of a relatively thin stainless steel sheet. Industrial applicability
