Detailed Description
For a more clear understanding of the technical features, objects and effects of the present invention, embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
As shown in fig. 1, an electronic atomizer according to some embodiments of the present invention includes an atomizer 1 and a power supply device 2 electrically connected to the atomizer 1. The atomizer 1 is used for accommodating liquid substrates such as tobacco liquid and liquid medicine and heating the liquid substrates to generate atomized gas, and the power supply device 2 is used for supplying power to the atomizer 1. As shown in the drawing, the lower end of the atomizer 1 is inserted into the upper end of the power supply unit 2, and the two are detachably combined.
As shown in fig. 2, the atomizer 1 may in some embodiments comprise a housing 18, a mouthpiece 19, and a heat generating component 13. The housing 18 has a reservoir 11 and an air flow passage 15 formed therein. Liquid substrates such as tobacco juice, liquid medicine and the like are stored in the liquid storage cavity 11, and the heating component 13 is arranged in the shell 18 and is in fluid communication with the liquid storage cavity 11 and used for heating and atomizing the liquid substrates stored in the liquid storage cavity 11. The suction nozzle 19 can be arranged at the upper end of the housing 18, in this embodiment, the suction nozzle 19 is arranged at the upper end of the housing 18 in a covering manner, the air flow channel 15 is in air-guiding connection with the heating element 13 and the suction nozzle 19, and when the air circulates, the air flow channel 15 brings the atomized air generated after the heating element 13 is heated and atomized to the suction nozzle 19 for a user to suck.
The air flow channel 15 includes an air inlet channel 151, an air outlet channel 153, and an atomizing channel 152 communicating the air inlet channel 151 and the air outlet channel 153, the air inlet channel 151 communicating with the outside air, and the air outlet channel 153 communicating with the suction nozzle 19. When a user sucks, the air sequentially passes through the air inlet channel 151, the atomizing channel 152 and the air outlet channel 153 to the suction nozzle 19, and the atomized air of the heating component 13 is driven to be sucked by the user.
An air intake hole 183 may be formed in the housing 18, and external air may be introduced into the air intake passage 151 through the air intake hole 183. An air inlet pipe 184 communicated with the air inlet hole 183 and an air outlet pipe 185 communicated with the suction nozzle 19 may be further formed in the housing 18. The intake passage 151 may include a first intake passage 1511 formed by an inner wall of the intake pipe 184, and a second intake passage 1512 that communicates the first intake passage 1511 and the atomizing passage 152, respectively. Air outlet channel 153 may include a second air outlet channel 1532 formed by an inner wall of air outlet pipe 185, and a first air outlet channel 1531 communicating nebulizing channel 152 and second air outlet channel 1532, respectively.
The first isolation portion 181 and the second isolation portion 182 are disposed in the housing 18, and both the first isolation portion 181 and the second isolation portion 182 can be integrally injection-molded with the housing 18, and can be formed by integrally extending the inner wall of the housing 18 downward. An air inlet pipe 184 and an air outlet pipe 185 are respectively formed between the first isolation part 181 and the second isolation part 182 and the shell 18. In this embodiment, the air inlet hole 183 may be opened at the top of the air inlet pipe 184, and the air inlet hole 183 is formed by a gap left between the outer shell 18 and the first isolation portion 181, so as to avoid specially forming a hole on the outer shell 18, save the processing technology, and ensure the aesthetic property and integrity of the product appearance. In other embodiments, the air intake holes 183 may also be opened on the side of the air intake pipe 184 near the top.
The atomizer 1 may further include a first flow restriction 161 in some embodiments, the first flow restriction 161 may have a tubular shape, and the first flow restriction 161 is inserted into the inlet pipe 184 along an axial direction of the first inlet channel 1511 to adjust an inlet cross-sectional area of the inlet pipe 184. The contact part of the first flow restriction 161 and the air inlet pipe 184 is in interference fit to form a sealing connection, so as to effectively prevent liquid leakage. The first flow restriction 161 is usually made of a flexible material, preferably a silicone material, and has a better sealing property at a contact portion with the air inlet pipe 184.
Since the intake cross-sectional area of the first flow restriction 161 is smaller than the intake cross-sectional area of the intake pipe 184, leakage of liquid from the intake pipe 184 can be alleviated. In some embodiments, the cross-sectional air inlet area of the first restriction 161 is within a set range in which the inner surface of the first restriction 161 is capable of forming a surface tension film that prevents condensate or liquid accumulation at the bottom of the atomizer 1 from flowing out of the atomizer 1 through the inlet tube 184. The intake cross-sectional area of the first restrictor 161 may be selected according to the material of the first restrictor 161. In some embodiments, the first restriction 161 has an intake cross-sectional area of 0.8-1.2mm2E.g. 1.0mm2Or 1.1 mm2. Within the range, the good ventilation effect can be ensured, and liquid leakage can be effectively prevented.
In some embodiments, the first flow restriction 161 may be disposed at a lower end of the intake pipe 184. Because the lower end of the air inlet pipe 184 is usually provided with a chamfer, when the air inlet pipe 184 is horizontally placed or the suction posture changes, condensate is easy to enter the air inlet pipe 184 along the chamfer of the lower end to form leakage, so the lower end surface of the first flow limiting piece 161 can be flush with the lower end surface of the air inlet pipe 184, the positioning is convenient to mount, and in addition, the problem of leakage of the liquid matrix from the air inlet pipe 184 caused by shaking in the transportation process can be solved.
With continued reference to fig. 2, the nebulizer 1 may further include a second flow restriction member 162 in some embodiments, the second flow restriction member 162 may be tubular, and the second flow restriction member 162 is plugged into the outlet tube 185 along an axial direction of the second outlet channel 1532 to reduce an outlet cross-sectional area of the outlet tube 185 and alleviate leakage from the outlet tube 185. In addition, because the second flow restriction 162 has a smaller outlet cross-sectional area, the atomized gas can be more concentrated when entering the outlet pipe 185, and the mouth feel is more lingering.
The contact part of the second flow restriction member 162 and the air outlet pipe 185 is in interference fit to form a sealing connection, so that liquid leakage is effectively prevented. The second restriction 162 is usually made of a flexible material, preferably a silicone material, and has a better sealing property at a contact portion with the outlet pipe 185.
The second flow restriction 162 may be provided at a lower end portion of the outlet pipe 185. Because the lower end part of the air outlet pipe 185 is usually provided with a chamfer, liquid leakage is easily formed at the chamfer of the lower end part when the air outlet pipe 185 is horizontally placed or the suction posture is changed, the lower end surface of the second flow limiting piece 162 can be flush with the lower end surface of the air outlet pipe 185, so that the positioning during installation can be facilitated, and in addition, the problem that liquid matrix leaks from the air outlet pipe 185 due to shaking in the transportation process can be solved.
The outlet cross-sectional area of the second restriction 162 may be selected according to the material of the second restriction 162. In some embodiments, the outlet cross-sectional area of the second restriction 162 ranges from 3.5 mm to 4.0mm2E.g. 3.75 mm2。
Referring to fig. 2-6, in some embodiments, the atomizer 1 may further comprise a lower housing 14, a sealing boot 172, and an upper housing 12. The heating element 13 has a liquid absorbing surface 131 facing the liquid storage chamber 11 and an atomizing surface 132 opposite to the liquid absorbing surface 131, the heating element 13 is accommodated in a space formed between the lower seat 14 and the upper seat 12, the liquid absorbing surface 131 and the atomizing surface 132 of the heating element 13 are respectively opposite to the upper seat 12 and the lower seat 14, and the upper seat 12, the first isolation portion 181 and the second isolation portion 182 define the liquid storage chamber 11 together.
The bottom of the housing 18 is open, the lower base 14 fits in the opening, the heating element 13 is disposed on the lower base 14, the sealing sleeve 172 is sleeved outside the heating element 13, and the upper base 12 at least partially surrounds the upper portion of the heating element 13 and abuts against the sealing sleeve 172. After the upper seat body 12 is pressed against the sealing sleeve 172, the heating component 13 is tightly clamped between the lower seat body 14 and the upper seat body 12, so that the structure is stable, and the assembly is convenient. The existence of the sealing sleeve 172 can realize the sealing between the heating component 13 and the upper seat body 12, and prevent liquid leakage; it is also possible to make the positioning of the heat generating component 13 in the horizontal direction more compact. The sealing sleeve 172 is generally made of a flexible material, preferably a silicone material, and has better sealing performance.
The lower housing 14 may include a base 141, a first supporting arm 142 extending from the base 141, and a second supporting arm 143 extending from the base 141 and disposed opposite to the first supporting arm 142, wherein the first supporting arm 142 and the second supporting arm 143 may respectively extend integrally from the top of the base 141 toward the heat generating component 13. The heating element 13 is supported between the first supporting arm 142 and the second supporting arm 143, the atomizing surface 132 of the heating element faces the base 141, and has a certain distance with the base 141, and the distance forms an atomizing channel 152 for mixing the atomized atomizing gas of the heating element 13 with the outside air.
The base 141 may be in a flat plate shape in some embodiments, and may have a vent 1413 formed thereon for communicating the air inlet channel 151 with the outside of the atomizer 1, a vent tube 163 extending into the air inlet channel 151 is disposed in the vent 1413, one end (air inlet end) of the vent tube 163 extends into the air inlet channel 151, and the other end (air outlet end) is communicated with a pneumatic switch in the power supply unit 2, so that external air may enter the battery unit 2 from the air inlet channel 151 along the vent tube 163, so that the pneumatic switch in the power supply unit 2 can sense suction or gas flow, and when a user sucks, the pneumatic switch detects the passing of air flow, and sends a signal to the controller, so that the power supply unit 2 supplies power to the heating element 13 of the atomizer 1.
The air vent pipe 163 can be inserted into the side of the base 141 opposite to the air inlet channel 151 along the axial direction of the air vent 1413, and the air inlet end of the air vent pipe 163 extends into the air inlet channel 151 and is higher than the surface of the base 141 around the air inlet end, so that the liquid leakage of the atomizer 1 is not easy to enter the air vent pipe 163, and the risk of liquid entering the power supply device 2 from the air vent pipe 163 can be reduced.
Snorkel 163 is a vertical elongated tube that is convenient to manufacture and assemble. In other embodiments, snorkel 163 may also be a bent elongated tube. Since breather pipe 163 is thin and long, a small amount of condensate adheres to breather pipe 163 due to surface tension, and does not easily enter power supply device 2. In some embodiments, snorkel 163 is metal, preferably stainless steel, which is easily molded and rust resistant.
Breather pipe 163 and heating element 13 stagger the setting, and breather pipe 163 is not located heating element 13 directly below, avoids the direct liquid that falls into breather pipe 163 of heating element 13 below condensation, reduces the risk that liquid flows to power supply unit 2 one side by breather pipe 163.
The first supporting arm 142 and the second supporting arm 143 are respectively located at two opposite sides of the heat generating component 13, and are used for supporting and mounting the heat generating component 13 and the upper seat 12. The inner side surfaces of the first supporting arm 142 and the second supporting arm 143 are further provided with a first receiving groove 1422 and a second receiving groove 1432, which are recessed respectively, so that the nesting portion 122 of the upper base 12 is embedded therein. The first receiving groove 1422 and the second receiving groove 1432 are formed in the upper half portions of the first support arm 142 and the second support arm 143, respectively, and a first step 1421 and a second step 1431 are formed in the first support arm 142 and the second support arm 143, respectively. Both ends of the heat generating component 13 are respectively overlapped on the first step 1421 and the second step 1431. The first supporting arm 142 and the second supporting arm 143 are further respectively provided with a locking groove 146 for locking with the upper seat 12, and the locking groove 146 can be respectively formed on the side walls of the first receiving groove 1422 and the second receiving groove 1432. The nesting portion 122 is provided with a hook 1221 engaged with the slot 146, and when the nesting portion 122 is nested in the first receiving slot 1422 and the second receiving slot 1432, the hook 1221 and the slot 146 are fastened and fixed to each other, so as to fasten the upper housing 12 and the lower housing 14 together.
The first support arm 142 is disposed on the opposite side of the base 141 from the intake passage 151. The first support arm 142 may further have a blocking wall 144 for separating the atomizing passage 152 from the air inlet passage 151, and the blocking wall 144 may have at least one air inlet micro hole 1441 transversely formed therein for communicating the air inlet passage 151 and the atomizing passage 152, and the at least one air inlet micro hole 1441 may facilitate the air flow. The blocking wall 144 can be flat, the blocking wall 144 can prevent the effusion carried on the base 141 from flowing out of the atomizer 1, and in addition, the blocking wall 144 can also block a part of the atomized gas atomized by the heating component 13, so as to prevent the atomized gas from being shunted to the air inlet channel 151, so that the atomized gas flows to the suction nozzle 19 along the air outlet channel 153, and the taste of the atomized gas is fuller. The blocking wall 144, the first supporting arm 142 and the second supporting arm 143 can be integrally injection molded with the base 141.
In this embodiment, the blocking wall 144 is provided with a plurality of air inlet micro holes 1441, and the plurality of air inlet micro holes 1441 may be distributed in a honeycomb shape or in a uniform array. In some embodiments, the air inlet cross-sectional area of each air inlet micro-hole 1441 is within a set range, and the inner surface of the air inlet micro-hole 1441 can form a surface tension film, which can further prevent the accumulated liquid from flowing out of the atomizer 1, thereby preventing the atomizer 1 from leaking liquid. In some embodiments, each air inlet micro-hole 1441 has a diameter of 0.1-0.6mm, such as 0.5mm, to enable surface tension to be created at the surface of the hole. In some embodiments, the total cross-sectional area of the plurality of air inlet micro-holes 1441 is 1.2-2.0mm2E.g. 1.5mm2. Within the range, the good ventilation effect can be ensured, and liquid leakage can be effectively prevented.
The air intake end of snorkel 163 is spaced from plurality of air intake micro-holes 1441 to prevent liquid from entering snorkel 163 directly through air intake micro-holes 1441. In some embodiments, the air intake end of snorkel 163 is not lower than the lowest position of plurality of air intake micro-holes 1441, i.e., the air intake end of snorkel 163 is not lower than the position of lowest air intake micro-hole 1441. Preferably, the air inlet end position of air pipe 163 is higher than the highest position of the plurality of air inlet micro holes 1441, that is, the air inlet end position of air pipe 163 is higher than the position of the highest air inlet micro hole 1441.
The second supporting arm 143 is disposed on a side of the base 141 opposite to the gas outlet channel 153, the second supporting arm 143 may be formed by extending an edge of one side of the base 141 upward, and a gap 145 for the passage of the atomizing gas is formed between the second supporting arm 143 and the base 141.
Because the first support arm 142 and the second support arm 143 have different structures, in order to prevent the lower seat 14 from being assembled reversely and improve the assembly efficiency, the lower seat 14 and the upper seat 12 may further be respectively provided with a fool-proof structure for mutual matching, so as to ensure that the lower seat 14 and the upper seat 12 can be assembled in a correct direction, so that the first support arm 142 and the second support arm 143 are respectively opposite to the air inlet channel 151 and the air outlet channel 153, thereby ensuring that the lower seat 14 and the upper seat 12 are assembled and matched smoothly. The fool-proof structure may include a first fool-proof portion disposed on the first supporting arm 142 and/or the second supporting arm 143, and a second fool-proof portion disposed on the upper body 12 and engaged with the first fool-proof portion in a mutual convex-concave manner.

The liquid absorbing member 147 is disposed in the receiving groove 1411 for absorbing the accumulated liquid received on the base 141. The absorbent member 147 can typically be absorbent cotton.
In some embodiments, the top surface of the base 141 can include a liquid guiding slope 1412, and the accumulated liquid received on the base 141 can flow back to the liquid absorbing member 147 through the liquid guiding slope 1412, and be absorbed by the liquid absorbing member 147, so as to avoid liquid accumulation and alleviate liquid leakage; meanwhile, the gurgling sound caused by the sound during the pumping can be avoided.
In some embodiments, the fluid-directing ramp 1412 is disposed corresponding to the gap 145, and the fluid-directing ramp 1412 and the second support arm 143 define the gap 145 together. The fluid-directing ramp 1412, which in some embodiments may be a sloped surface, may have a first slope that slopes downwardly from the edge of the base 141 toward the fluid-absorbing member 147 to facilitate the flow of fluid on the base 141 toward the fluid-absorbing member 147. In some embodiments, the fluid-guiding slope 1412 may further have a second slope that is inclined downward from one side of the second supporting arm 143 contacting the base 141 to the other side, so as to facilitate the backflow of the accumulated fluid and the mold stripping of the lower housing 14 during the injection molding.
The base 141 and the housing 18 are sealingly connected to prevent leakage. The atomizer 1 may further include a first sealing member 173 disposed between the base 141 and the housing 18 in some embodiments, and the first sealing member 173 is annular and is sleeved outside the base 141. The first sealing member 173 is usually made of a flexible material, preferably a silicone material, and has better sealing performance.
The upper housing 12 is disposed in the reservoir chamber 11 and is in fluid communication with the reservoir chamber 11. The upper housing 12 may include a main body 121 having a substantially rectangular parallelepiped shape, a nest 122 extending downward from the bottom of the main body 121, and a first inlet 1211 and at least a second inlet 1212 for communicating the reservoir 11 and the heat generating component 13. The nesting portion 122 is annular, and is received in the first receiving groove 1422 and the second receiving groove 1432 between the first supporting arm 142 and the second supporting arm 143 of the lower base 141, and is sleeved outside the sealing sleeve 172.
The first liquid inlet 1211 and the at least one second liquid inlet 1212 both penetrate the body 121 in a longitudinal direction. The cross-sectional area of the inner hole of each second liquid inlet hole 1212 is smaller than the cross-sectional area of the inner hole of the first liquid inlet hole 1211, so that the liquid dropping rate/liquid flow rate of the first liquid inlet hole 1211 is larger than the liquid dropping rate/liquid flow rate of the at least one second liquid inlet hole 1212, the first liquid inlet hole 1211 is mainly used for dropping liquid, the at least one second liquid inlet hole 1212 is used for dropping liquid and assisting in ventilation, and dry burning caused by insufficient ventilation of the heating element 13 is relieved.
