Description

Technical Field

[0001] The present invention relates to the technical field of electronic atomization, and particularly to a leak-proof atomizer and a leak-proof atomization device. Background Art

[0002] Regarding large-capacity electronic cigarettes, that is, large-capacity atomization devices, due to the large capacity of the electronic cigarettes, when not in use by suction, the atomization core is in an unheated state, making the e-liquid of the electronic cigarette prone to leakage. To solve the problem of e-liquid leakage in electronic cigarettes, generally, an oil storage cotton is arranged in the oil tank, such as in Patent CN111671161A.

[0003] For the above-mentioned electronic cigarettes, although the problem of easy leakage is solved, to a certain extent, the capacity of the e-liquid is also reduced a lot. Affected by the structure of the oil storage cotton, the heating component can only select a relatively long atomization core with a tracheal structure. Moreover, when refilling the liquid, affected by the structure of the oil storage cotton, the oil supply rate of the electronic cigarette is relatively low. Summary of the Invention

[0004] An object of the present invention is to overcome the deficiencies in the prior art and provide a leak-proof atomizer and a leak-proof atomization device that can not only avoid easy leakage but also improve the oil supply rate.

[0005] The object of the present invention is achieved by the following technical solutions:

[0006] A leak-proof atomizer, comprising:

[0007] An atomizer main body, which forms a liquid storage cavity, a liquid inlet hole and an atomization cavity. The liquid storage cavity is communicated with the atomization cavity through the liquid inlet hole. A guiding chute is formed on the inner wall of the liquid storage cavity, and the guiding chute is communicated with the liquid inlet hole;

[0008] A rolling plugging member, which is rollably arranged in the liquid storage cavity; the rolling plugging member is used to roll along the guiding chute to the liquid inlet hole when the atomizer main body is at a predetermined angular position, so as to limit the liquid inlet rate of the liquid inlet hole.

[0009] In one embodiment, the atomizer main body includes a liquid storage member and a sealed atomization seat;

[0010] The liquid storage member forms a liquid storage tank; the sealed atomization seat is located in the liquid storage tank and is hermetically connected to the liquid storage member to form the liquid storage cavity;

[0011] The sealed atomization seat forms a liquid inlet hole and an atomization cavity that are communicated with each other. The liquid inlet hole is also communicated with the liquid storage tank. The guiding chute is formed on the end side of the sealed atomization seat exposed to the liquid storage tank.

[0012] In one embodiment, the number of the liquid inlet holes is at least two, and each of the liquid inlet holes is communicated with the liquid storage cavity; the number of the rolling blocking members is at least two, and the number of the guiding chutes is at least two. Each of the guiding chutes is communicated with a corresponding one of the liquid inlet holes, and each of the rolling blocking members is configured to roll along the guiding chute to a position corresponding to the liquid inlet hole when the atomizer body is at a predetermined angular position.

[0013] In one embodiment, the rolling blocking member has a spherical structure, and the cross-sectional area of the outer wall contour of the rolling blocking member in contact with the liquid inlet hole when the atomizer body is at a predetermined angular position is smaller than the maximum cross-sectional area of the rolling blocking member.

[0014] In one embodiment, the liquid inlet hole is a polygonal hole or a circular hole.

[0015] In one embodiment, the density of the rolling blocking member is greater than the density of the atomized liquid.

[0016] In one embodiment, the rolling blocking member includes a first rolling hemispherical member and a second rolling hemispherical member, and the first rolling hemispherical member and the second rolling hemispherical member are detachably connected.

[0017] In one embodiment, both the first rolling hemispherical member and the second rolling hemispherical member are rolling hemispherical shell sleeves, and a hollow cavity is jointly formed by the first rolling hemispherical member and the second rolling hemispherical member.

[0018] In one embodiment, the rolling blocking member further includes a spherical core body, and the spherical core body is located in the hollow cavity.

[0019] A leak-proof atomizing device includes the leak-proof atomizer according to any one of the above embodiments.

[0020] Compared with the prior art, the present invention has at least the following advantages:

[0021] The above leak-proof atomizer has guide chutes formed on the inner wall of the liquid storage cavity. The guide chutes communicate with the liquid inlet holes, enabling the atomized liquid in the liquid storage cavity to quickly flow into the liquid inlet holes through the guide chutes. Subsequently, the atomized liquid rapidly flows into the atomization cavity through the liquid inlet holes for heating and atomization. Additionally, since the rolling sealing member is rotatably arranged in the liquid storage cavity, when the atomizer body is at a predetermined angle position, the rolling sealing member rolls along the guide chute to the position corresponding to the liquid inlet hole, thereby at least partially blocking the liquid inlet hole. As a result, the liquid inlet rate of the liquid inlet hole is restricted or regulated, causing the atomized liquid passing through the liquid inlet hole to automatically decrease when the atomizer body is at the predetermined angle position, preventing the occurrence of liquid leakage due to high pressure at the liquid inlet hole, especially for large-capacity atomization devices when not in use. Moreover, the rolling sealing member is directly placed in the atomized liquid within the liquid storage cavity, eliminating the need to install an oil storage cotton in the liquid storage cavity (i.e., the oil tank). This makes the structure of the leak-proof atomizer more compact and avoids the problem of low oil supply efficiency in electronic cigarettes. Brief Description of the Drawings

[0030] To facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. The preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of the present invention more thorough and comprehensive.

[0031] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may also be a middle element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be a middle element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for illustrative purposes and do not represent the only embodiments.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0033] This application provides an anti-leakage atomizer, including an atomizer body and a rolling seal; the atomizer body is formed with a liquid storage cavity, a liquid inlet hole and an atomization cavity, the liquid storage cavity is communicated with the atomization cavity through the liquid inlet hole, a guiding chute is formed on the inner wall of the liquid storage cavity, and the guiding chute is communicated with the liquid inlet hole; the rolling seal is arranged to roll in the liquid storage cavity; the rolling seal is used to roll to the liquid inlet hole along the guiding chute when the atomizer body is at a predetermined angular position, so as to limit the liquid inlet rate of the liquid inlet hole.

[0034] The above leak-proof atomizer has a guiding chute formed on the inner wall of the liquid storage cavity. The guiding chute communicates with the liquid inlet hole, enabling the atomizing liquid in the liquid storage cavity to quickly flow into the liquid inlet hole through the guiding chute. Then, the atomizing liquid quickly flows into the atomizing cavity through the liquid inlet hole for heating and atomization. Also, since the rolling plug is rotatably arranged in the liquid storage cavity, when the atomizer body is at a predetermined angle position, the rolling plug rolls along the guiding chute to the position corresponding to the liquid inlet hole, so that at least part of the liquid inlet hole is blocked by the rolling plug, thereby restricting or regulating the liquid inlet rate of the liquid inlet hole. In this way, the atomizing liquid passing through the liquid inlet hole is automatically reduced when the atomizer body is at a predetermined angle position, avoiding the leakage situation that is likely to occur due to the relatively high pressure at the liquid inlet hole, especially for a large-capacity atomizing device when not in use. And the rolling plug is directly placed in the atomizing liquid in the liquid storage cavity, eliminating the need to provide an oil storage cotton in the liquid storage cavity, i.e., the oil tank. Thus, the structure of the leak-proof atomizer is relatively compact, and the problem of low oil supply efficiency of the electronic cigarette is avoided.

[0035] To better understand the technical solutions and beneficial effects of the present application, the following further elaborates on the present application with specific embodiments:

[0036] As Figures 1 to 3 shown, a leak-proof atomizing device 10 in an embodiment includes a leak-proof atomizer 100, and the leak-proof atomizer 100 includes an atomizer body 110 and a rolling plug 120. The atomizer body 110 forms a liquid storage cavity 102, a liquid inlet hole 104, and an atomizing cavity 106. The liquid storage cavity 102 communicates with the atomizing cavity 106 through the liquid inlet hole 104. A guiding chute 1022 is formed on the inner wall of the liquid storage cavity 102. The guiding chute 1022 communicates with the liquid inlet hole 104, enabling the atomizing liquid in the liquid storage cavity 102 to quickly and reliably flow into the liquid inlet hole 104 through the guiding chute 1022. The guiding chute 1022 communicates with the liquid storage cavity 102 and the liquid inlet hole 104 respectively.

[0037] As Figures 1 to 3 shown, in one of the embodiments, the cross-sectional area of the liquid storage cavity 102 is larger than the cross-sectional area of the liquid inlet hole 104, accelerating the flow rate of the atomizing liquid through the guiding chute 1022, and thus enabling the atomizing liquid to better flow into the liquid inlet hole 104. The liquid storage cavity 102 is used to store the atomizing liquid. For example, the atomizing liquid can be e-liquid or liquid medicine or other atomizing liquids.

[0038] As Figures 1 to 3As shown, in one embodiment, the rolling plug 120 is rotatably disposed in the liquid storage cavity 102; the rolling plug 120 is configured to roll along the guiding chute 1022 to the liquid inlet hole 104 when the atomizer body 110 is at a predetermined angular position, that is, the rolling plug 120 rolls along the guiding chute 1022 to a position corresponding to the liquid inlet hole 104 when the atomizer body 110 is at a predetermined angular position, so that at least a part of the liquid inlet hole 104 is blocked by the rolling plug 120. At this time, the cross-section of the liquid inlet hole 104 through which the atomized liquid passes is reduced to limit the liquid inlet rate of the liquid inlet hole 104, thereby restricting or regulating the liquid inlet rate of the liquid inlet hole 104. In this embodiment, at least a part of the rolling plug 120 is immersed in the atomized liquid. The rolling plug 120 is simultaneously affected by gravity and buoyancy, and the gravity of the rolling plug 120 is always greater than the buoyancy, so that the rolling plug 120 can roll to the liquid injection hole at a predetermined angular position.

[0039] For the above leak-proof atomizer 100, since the inner wall of the liquid storage cavity 102 is formed with a guiding chute 1022, and the guiding chute 1022 is communicated with the liquid inlet hole 104, the atomized liquid in the liquid storage cavity 102 quickly flows into the liquid inlet hole 104 through the guiding chute 1022. Then, the atomized liquid quickly flows into the atomization cavity 106 through the liquid inlet hole 104 for heating and atomization. Also, since the rolling plug 120 is rotatably disposed in the liquid storage cavity 102, the rolling plug 120 rolls along the guiding chute 1022 to the liquid inlet hole 104, that is, to a position corresponding to the liquid inlet hole 104 when the atomizer body 110 is at a predetermined angular position, so that at least a part of the liquid inlet hole 104 is blocked by the rolling plug 120, thereby restricting or regulating the liquid inlet rate of the liquid inlet hole 104. In this way, the atomized liquid passing through the liquid inlet hole 104 is automatically reduced when the atomizer body 110 is at a predetermined angular position, avoiding the leakage caused by the relatively high pressure at the liquid inlet hole 104, especially for a large-capacity atomization device when not in use. The rolling plug 120 is directly placed in the atomized liquid in the liquid storage cavity 102, and there is no need to provide an oil storage cotton in the liquid storage cavity 102, that is, the oil tank. Thus, the structure of the leak-proof atomizer 100 is relatively compact, and the problem of low oil supply efficiency of the electronic cigarette is avoided.

[0040] Furthermore, the predetermined angular position is 80° to 90°. When the predetermined angular position is 90°, that is, when the atomizer body 110 is in a position perpendicular to the horizontal plane, according to the force analysis, at this time, the resultant force of the rolling plug 120 moving downward is relatively large, so that the rate at which the rolling plug 120 rolls into the liquid inlet hole 104 is relatively fast. When the predetermined angular position is 90°, at this time, the atomizer body 110 is in a vertical position, that is, the atomizer body 110 is in a vertical position. At this time, the rolling rate of the rolling plug 120, that is, the rolling sensitivity, is good. At this time, the leak-proof atomizer 100 can be in a vertically placed, that is, unused, situation or a vertically held situation.

[0041] As Figure 4 shown, further, the cross-section of the guiding chute 1022 is formed with an inclined surface 1023, and the inclination angle of the inclined surface 1023 is 5° to 10°, so that the guiding chute 1022 has a good effect of guiding rolling.

[0042] As Figure 3 and Figure 4 shown, in one embodiment, the atomizer body 110 includes a liquid storage member 110a and a sealed atomizing seat 110b. Among them, the liquid storage member 110a is formed with a liquid storage tank 108, and the sealed atomizing seat 110b is located in the liquid storage tank 108 and is hermetically connected to the liquid storage member 110a to form the liquid storage cavity 102. Further, the sealed atomizing seat 110b is formed with a liquid inlet hole 104 and an atomizing cavity 106 that communicate with each other, and the liquid inlet hole 104 also communicates with the liquid storage tank 108. The end side of the sealed atomizing seat 110b exposed in the liquid storage tank 108 is formed with the guiding chute 1022.

[0043] As Figure 3 and Figure 4As shown, further, the sealed atomizing base 110b includes a seal 112, an atomizing base 114, and an atomizing core 116. The seal 112 and the liquid storage member 110a are both sleeved on the atomizing base 114. The atomizing base 114 abuts against the seal 112. The liquid inlet hole 104 and the atomizing chamber 106 are both formed in the seal 112. The atomizing core 116 is disposed on the atomizing base 114, and the liquid inlet hole 104 communicates with one side of the atomizing surface of the atomizing core 116, enabling the atomizing core 116 to reliably heat and atomize the atomizing liquid passing through the liquid inlet hole 104. Further still, a liquid guiding member 1125 is provided on one side of the seal 112 adjacent to the atomizing core 116. The liquid guiding member 1125 abuts against the atomizing core 116, that is, the atomizing surface of the atomizing core 116 abuts against the liquid guiding member 1125 surface to surface. The liquid inlet hole 104 guides the liquid to the atomizing surface through the liquid guiding member 1125 for heating and atomizing, improving the liquid leakage prevention effect of the liquid leakage prevention atomizer 100. In this embodiment, the liquid guiding member 1125 is a liquid guiding cotton or a liquid guiding ceramic. Specifically, an installation groove 1126 is formed on one side of the seal 112 adjacent to the atomizing core 116, and the liquid guiding member 1125 is disposed in the installation groove 1126, enabling the liquid guiding member 1125 to be better received in the seal 112.

[0044] As Figure 3 and Figure 4 shown, further still, a liquid passing channel 1127 communicating with the installation groove 1126 is formed on one side of the seal 112 adjacent to the atomizing core 116. The liquid passing channel 1127 communicates with the liquid inlet hole 104, enabling a part of the atomizing liquid flowing out of the liquid inlet hole 104 to enter the liquid guiding member 1125, and the other part to flow into the middle position of the liquid guiding member 1125 through the liquid passing channel 1127, avoiding the situation of dry burning easily occurring at the middle position of the liquid guiding member 1125 due to the lack of atomizing liquid, and improving the atomizing effect of the liquid leakage prevention atomizer 100.

[0045] As Figure 3 , Figure 4 and Figure 5 shown, further still, the atomizing base 114 forms a stepped peripheral edge 1142, and a socket flange 1128 is formed on one side of the seal 112 adjacent to the atomizing base 114, enabling the seal 112 to be tightly connected to the atomizing base 114. The socket flange 1128 forms an air outlet 1129 for avoiding position, and the air outlet 1129 for avoiding position communicates with the atomizing chamber 106, enabling the atomizing gas in the atomizing chamber 106 to reliably discharge. The stepped peripheral edge 1142 is located outside the installation groove 1126, and the socket flange 1128 forms a positioning groove 1121 communicating with the installation groove 1126. The end surface of the atomizing base 114 is located in the positioning groove 1121 and is sleeved with the socket flange 1128, enabling the seal 112 to be better positioned on the socket flange 1128. Also refer to Figure 6, Further, an annular flange 1131 protrudes from the inner wall of the positioning groove 1121, and an annular groove 1143 is formed on the stepped periphery 1142. The annular flange 1131 is snapped into the annular groove 1143, and a flow-through port 1133 is formed at the corresponding position between the annular flange 1131 and the avoidance air outlet 1129, so that the atomized gas in the atomization chamber 106 can reliably enter the central tube 1024 through the flow-through port 1133 and the avoidance air outlet 1129.

[0046] As Figure 3 and Figure 4 shown, even further, the atomization base 114 is formed with an air inlet hole 1141, an air inlet chamber 1143 and an air inlet passage 1145 that are connected in sequence. The air inlet hole 1141 is connected to the atomization chamber 106, so that the peripheral air flow sequentially passes through the air inlet hole 1141, the air inlet chamber 1143 and the air inlet passage 1145 and flows into the atomization chamber 106 for heating and atomization, realizing reliable atomization. In this embodiment, the air inlet chamber 1143 is located below the atomization chamber 106. Even further, the anti-liquid leakage atomizer 100 further includes an anti-liquid leakage member 130, and the anti-liquid leakage member 130 is disposed in the air inlet chamber 1143, so that the condensate generated in the air inlet passage 1145 directly drops onto the anti-liquid leakage member 130, so that the condensate liquid is reliably stored in the air inlet chamber 1143, avoiding damage to the electronic components of the anti-liquid leakage atomizer 100 such as the microphone member 140. In this embodiment, the position where the air inlet chamber 1143 is connected to the air inlet hole 1141 is higher than the inner bottom wall of the air inlet chamber 1143, avoiding the problem that the condensate liquid in the air inlet chamber 1143 is not easy to flow out of the air inlet hole 1141 and causing damage to the electronic components of the anti-liquid leakage atomizer 100. In this embodiment, the liquid passing channel 1127 is connected to the air inlet passage 1145.

[0047] In one embodiment, the number of the liquid inlet holes 104 is at least two, and each of the liquid inlet holes 104 is connected to the liquid storage chamber 102; the number of the rolling sealing members 120 is at least two, and the number of the guiding chutes 1022 is at least two. Each of the guiding chutes 1022 is connected to the corresponding liquid inlet hole 104. Each of the rolling sealing members 120 is used to roll along the guiding chute 1022 to the corresponding liquid inlet hole 104 when the atomizer body 110 is at a predetermined angular position, so that the liquid inlet rates of the two liquid inlet holes 104 can be limited or regulated at the predetermined angular position, and at the same time, the anti-liquid leakage atomizer 100 has a good liquid inlet effect during use, thereby improving the atomization effect of the anti-liquid leakage atomizer 100. In this embodiment, the number of the liquid inlet holes 104, the rolling sealing members 120 and the guiding chutes 1022 are all two. In other embodiments, the number of the liquid inlet holes 104, the rolling sealing members 120 and the guiding chutes 1022 can all be three or four, etc.

[0048] As Figure 3 and Figure 6 shown, further, a first limiting rib 102a is provided on the inner wall of the liquid storage cavity 102, a central tube 1024 parallel to the first limiting rib 102a is further provided on the inner wall of the liquid storage member 110a, the sealing member 112 is formed with a central insertion hole 112d, the central tube 1024 is inserted into the central insertion hole, and one end of the first limiting rib 102a abuts against and limits the sealing member 112, so that the sealing member 112 is reliably installed in the liquid storage cavity 102. In this embodiment, the distance between the first limiting rib 102a and the central tube 1024 is less than the minimum width of each rolling plugging member 120, and a liquid cross-flow area 1023 is formed between the first limiting rib 102a and the central tube 1024. The two rolling plugging members 120 are separately arranged on both sides of the liquid cross-flow area 1023 to avoid the situation where both rolling plugging members 120 are located on one side of the liquid cross-flow area 1023. It can be understood that the minimum width of each rolling plugging member 120 can be the diameter or length of the rolling plugging member 120. In this embodiment, the rolling plugging member 120 is a spherical structure, and the minimum width of the rolling plugging member 120 is the diameter of the rolling plugging member 120. Further, a second limiting rib 102b opposite to the first limiting rib 102a is convexly provided on the outer peripheral wall of the central tube 1024, the first limiting rib 102a and the second limiting rib 102b are arranged parallel to each other, and the liquid cross-flow area 1023 is formed between the first limiting rib 102a and the second limiting rib 102b. The second limiting rib 102b and the first limiting rib 102a jointly abut against and limit the sealing member 112, so that the rolling plugging member 120 is better limited and assembled in the liquid storage member 110a.

[0049] As Figure 3 and Figure 4As shown, further, the liquid inlet hole 104 includes a liquid inlet opening groove 104a, a buffer groove 104b, and a liquid inlet channel 104c. The liquid inlet opening groove 104a is respectively communicated with the liquid storage cavity 102, the buffer groove 104b, and the liquid inlet channel 104c. The buffer groove 104b is communicated with the liquid inlet channel 104c, so that part of the atomized liquid passing through the liquid inlet opening groove 104a is buffered in the buffer groove 104b, and the other part directly enters the liquid inlet channel 104c. Moreover, the atomized liquid located in the buffer groove 104b can also enter the liquid inlet channel 104c, enabling the buffer groove 104b to play a role in buffering the atomized liquid, avoiding the situation of easy liquid leakage due to excessive atomized liquid passing through the liquid inlet opening groove 104a during normal suction use, and also avoiding the situation of liquid leakage due to excessive pressure in the liquid inlet opening groove 104a when not in use, such as in the idle state. That is to say, when not in use, such as in the idle state, the buffer groove 104b plays a role in buffering the flow rate of the atomized liquid, and at the same time can bear a part of the pressure of the opening groove. With the combined action of the rolling sealing member 120, it can better avoid the situation of easy liquid leakage due to relatively large pressure at the liquid inlet hole 104. In this embodiment, one end of the liquid inlet channel 104c is communicated with the liquid inlet opening groove 104a, and the other end of the liquid inlet channel 104c is communicated to one side of the atomization core 116. The buffer groove 104b is communicated with the inner side wall of the liquid inlet channel 104c, so that the buffer groove 104b is communicated with the liquid inlet channel 104c.

[0050] As Figure 3 and Figure 4 shown, furthermore, the flow rate of the atomized liquid entering the liquid inlet channel 104c through the buffer groove 104b is less than the flow rate of the atomized liquid entering the liquid inlet channel 104c through the liquid inlet opening groove 104a, so that the buffer groove 104b has a good buffering effect on the atomized liquid.

[0051] As Figure 3 and Figure 4 shown, furthermore, the liquid inlet hole 104 further includes a side flow gap hole 104d. The buffer groove 104b is communicated with the liquid inlet channel 104c through the side flow gap hole 104d, so that the buffer groove 104b is reliably communicated with the inner side wall of the liquid inlet channel 104c. In this embodiment, the number of the side flow gap holes 104d is multiple, and the multiple side flow gap holes 104d are spaced along the depth direction of the buffer groove 104b, so that the atomized liquid in the buffer groove 104b can reliably flow into the liquid inlet channel 104c. Furthermore, the aperture of the side flow gap hole 104d is smaller than the aperture of the liquid inlet channel 104c, so that the flow rate of the atomized liquid entering the liquid inlet channel 104c through the side flow gap hole 104d is less than the flow rate of the atomized liquid directly passing through the liquid inlet channel 104c, and thus the atomized liquid is better buffered in the buffer groove 104b.

[0052] As Figure 3 and Figure 4As shown, further, a microfluidic groove opening 1044 is formed on the inner sidewall of the liquid inlet opening groove 104a. The microfluidic groove opening 1044 is respectively communicated with the liquid storage cavity 102 and the liquid inlet channel 104c, so that the atomized liquid flows in through the microfluidic groove opening 1044, avoiding the problem that the liquid inlet hole 104 cannot intake liquid because the rolling plug 120 blocks the liquid inlet hole 104 during normal use. For example, the problem that the atomized liquid of the liquid inlet hole 104 cannot flow in due to vertical holding during normal use. In this way, it is ensured that at least a small amount or a trace amount of atomized liquid is continuously replenished into the liquid inlet hole 104, and at the same time, the problem of liquid leakage caused by the pressure of the liquid storage cavity 102 during idling can be avoided.

[0053] As Figure 3 and Figure 4 shown, further, the seal 112 includes a plastic seat 112a and a silicone rubber coating sleeve 112b sleeved on the end side of the plastic seat 112a. Both the plastic seat 112a and the silicone rubber coating sleeve 112b are hermetically abutted against the inner peripheral wall of the liquid storage cavity 102. The liquid inlet opening groove 104a includes a first opening groove 1041 formed in the silicone rubber coating sleeve 112b and a second opening groove 1043 opened in the plastic seat 112a. The first opening groove 1041 is respectively communicated with the liquid storage cavity 102 and the second opening groove 1043. The second opening groove 1043 is respectively communicated with the buffer groove 104b and the liquid inlet channel 104c. The cross-sectional area of the first opening groove 1041 is smaller than that of the second opening groove 1043. The cross-sectional contour of the second opening groove 1043 surrounds the buffer groove 104b and the liquid inlet channel 104c. When the rolling plug 120 rolls to the liquid inlet hole 104, due to the formation of the microfluidic groove opening 1044 on the inner sidewall of the liquid inlet opening groove 104a, and the cross-sectional area of the first opening groove 1041 is smaller than that of the second opening groove 1043, it is avoided that the rolling plug 120 blocks the buffer groove 104b or the liquid inlet channel 104c, ensuring that a small amount or a trace amount of atomized liquid still continuously flows out of the liquid inlet channel 104c, and at the same time, the problem of liquid leakage of the leak-proof atomizer 100 can be avoided.

[0054] As Figure 3 , Figure 4 and Figure 6As shown, in this embodiment, the installation groove 1126 and the liquid passing channel 1127 are both formed in the plastic seat 112a. The silica gel coating sleeve 112b abuts against the first limiting rib 102a and the second limiting rib 102b respectively. Further, a clamping boss 112c is formed on the side of the silica gel coating sleeve 112b adjacent to the plastic seat 112a, the central jack 112d is formed in the clamping boss 112e, the plastic seat 112a is provided with a side air outlet 112f and a positioning hole 112k that communicate with each other, the clamping boss is snapped into the positioning hole, and the side air outlets are respectively communicated with the atomization chamber 106 and the central tube 1024, so that the atomization chamber 106 is communicated with the central tube 1024, and the atomized gas formed in the atomization chamber 106 can flow out of the central tube 1024 reliably.

[0055] As Figure 3 and Figure 4 shown, in one of the embodiments, the rolling plug 120 is a spherical structure, and the cross-sectional area of the outer wall contour of the rolling plug 120 in contact with the liquid inlet hole 104 when the atomizer body 110 is at a predetermined angular position is smaller than the maximum cross-sectional area of the rolling plug 120.

[0056] As Figure 3 and Figure 4 shown, in one of the embodiments, the liquid inlet hole 104 is a circular hole. In other embodiments, the liquid inlet hole 104 can also be a polygonal hole. For example, the liquid inlet hole 104 can also be a triangular hole or a quadrilateral hole or a pentagonal hole, etc.

[0057] As Figure 3 and Figure 4 shown, in one of the embodiments, the density of the rolling plug 120 is greater than the density of the atomization liquid, so that the gravity of the rolling plug 120 is always greater than the buoyancy force received by the rolling plug 120.

[0058] As Figure 3 , Figure 4 and Figure 7 shown, in one of the embodiments, the rolling plug 120 includes a first rolling hemispherical member 120a and a second rolling hemispherical member 120b, and the first rolling hemispherical member 120a and the second rolling hemispherical member 120b are detachably connected, so as to disassemble and assemble the rolling plug 120, improving the convenience of use of the leak-proof atomizer 100.

[0059] As Figure 3 , Figure 4 and Figure 7As shown, in one embodiment, both the first rolling hemispherical member 120a and the second rolling hemispherical member 120b are rolling hemispherical shell sleeves, and the first rolling hemispherical member 120a and the second rolling hemispherical member 120b together form a hollow cavity 101, while reducing the weight of the rolling plug 120 under the condition that the rolling plug 120 rolls to the liquid inlet hole 104 along the guiding chute 1022 when in a predetermined angular position in the atomizer body 110.

[0060] As Figure 3 , Figure 4 and Figure 7 shown, in one embodiment, the rolling plug 120 further includes a spherical core body 120c, and the spherical core body 120c is located in the hollow cavity. Since the first rolling hemispherical member 120a and the second rolling hemispherical member 120b are detachably connected, the spherical core body 120c in the hollow cavity can be replaced or maintained regularly, and spherical core bodies 120c of different weights can be placed according to the use requirements to adjust the overall weight of the rolling plug 120, improving the applicability of the rolling plug 120.

[0061] As Figure 3 , Figure 4 and Figure 7 shown, in one embodiment, the first rolling hemispherical member 120a and the second rolling hemispherical member 120b are threadedly connected, making the first rolling hemispherical member 120a and the second rolling hemispherical member 120b detachably connected. For example, a first thread 1201 is formed on the outer peripheral edge of the first rolling hemispherical member 120a, a second thread 1203 is formed on the inner peripheral wall of the second rolling hemispherical member 120b, and the first thread and the second thread are threadedly connected, making the first rolling hemispherical member 120a and the second rolling hemispherical member 120b threadedly connected. Another example is that a first thread is formed on the inner peripheral wall of the first rolling hemispherical member, a second thread is formed on the outer peripheral wall of the second rolling hemispherical member 120b, and the first thread and the second thread are threadedly connected, making the first rolling hemispherical member 120a and the second rolling hemispherical member 120b threadedly connected. It can be understood that in other embodiments, the first rolling hemispherical member 120a and the second rolling hemispherical member 120b are not limited to threaded connection. For example, the first rolling hemispherical member 120a and the second rolling hemispherical member 120b are snap-connected. Specifically, a plurality of snap-bulges are convexly provided on the outer peripheral edge of the first rolling hemispherical member 120a, a plurality of snap-grooves are formed on the inner peripheral wall of the second rolling hemispherical member 120b, and the plurality of snap-bulges are respectively snap-connected in the plurality of snap-grooves, making the first rolling hemispherical member 120a and the second rolling hemispherical member 120b snap-connected.

[0062] As Figure 3 , Figure 4 and Figure 7As shown, in one embodiment, the first rolling hemispherical member 120a and the second rolling hemispherical member 120b are both stainless steel casings, so that the first rolling hemispherical member 120a and the second rolling hemispherical member 120b both have better density. Specifically, the first rolling hemispherical member 120a and the second rolling hemispherical member 120b are both made of food-grade stainless steel. For example, the first rolling hemispherical member 120a and the second rolling hemispherical member 120b are both made of 304 stainless steel.

[0063] In one embodiment, the spherical core body 120c is a vitreous body or a ceramic body or other spherical core body 120c. In this embodiment, the spherical core body 120c is a vitreous body. Since the first rolling hemispherical member 120a and the second rolling hemispherical member 120b are detachably connected, for example, the first rolling hemispherical member 120a and the second rolling hemispherical member 120b are threadedly connected. During use, the spherical core body 120c of different weights can be replaced according to the weight requirement of the rolling plug 120, improving the convenience of use of the leak-proof atomizer 100.

[0064] It can be understood that in other embodiments, the first rolling hemispherical member 120a and the second rolling hemispherical member 120b are not limited to stainless steel casings. In one embodiment, the rolling plug 120 is an inflatable spherical structure, and an inflatable cavity is formed inside the rolling plug 120 for inflating the inflatable cavity, so that the density of the rolling plug 120 can be adjusted according to the inflation amount, that is, the density of the rolling plug 120 is changed by injecting air into the inflatable cavity. In one embodiment, the rolling plug 120 is a puncturable spherical shell structure, and the inflatable cavity is formed inside the rolling spherical shell for inflating the inflatable cavity as needed, and the gas in the inflatable cavity can be prevented from leaking out after inflation. In this embodiment, the rolling spherical shell is an elastic spherical shell. Specifically, the elastic spherical shell is a silicone spherical shell, so that the elastic spherical shell has good elasticity and repeatable puncturability for puncturing and inflating the inflatable cavity, and at the same time, the air leakage after inflation is avoided.

[0065] Compared with the prior art, the present invention has at least the following advantages:

[0066] The above leak-proof atomizer 100 has a guiding chute 1022 formed on the inner wall of the liquid storage chamber 102. The guiding chute 1022 communicates with the liquid inlet hole 104, enabling the atomized liquid in the liquid storage chamber 102 to quickly flow into the liquid inlet hole 104 through the guiding chute 1022. Then, the atomized liquid quickly flows into the atomization chamber 106 through the liquid inlet hole 104 for heating and atomization. Also, since the rolling sealing member 120 is rotatably arranged in the liquid storage chamber 102, when the atomizer body 110 is at a predetermined angular position, the rolling sealing member 120 rolls along the guiding chute 1022 to the position corresponding to the liquid inlet hole 104, that is, the position where the liquid inlet hole 104 is located, so that at least part of the liquid inlet hole 104 is blocked by the rolling sealing member 120, thereby restricting or regulating the liquid inlet rate of the liquid inlet hole 104. In this way, the atomized liquid passing through the liquid inlet hole 104 is automatically reduced when the atomizer body 110 is at a predetermined angular position, avoiding the leakage of liquid that is likely to occur due to the relatively large pressure at the liquid inlet hole 104, especially for a large-capacity atomization device when not in use. The rolling sealing member 120 is directly placed in the atomized liquid in the liquid storage chamber 102, and there is no need to provide an oil storage cotton in the liquid storage chamber 102, that is, the oil tank. Thus, the structure of the leak-proof atomizer 100 is relatively compact, and the problem of low oil supply efficiency of the electronic cigarette is avoided.

[0067] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the invention patent should be subject to the appended claims.
