Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and in particular to an atomizer and an electronic cigarette. Background Technology

[0002] Electronic cigarettes consist of two parts: an atomizer and a frame. The atomizer stores e-liquid in a reservoir to provide sufficient fuel for subsequent use, and atomizes the e-liquid into vapor that can be inhaled through a heating chamber. The frame is used to provide electrical power.

[0003] In existing atomizers, the e-liquid reservoir and the heating chamber are not completely isolated; they are interconnected through an e-liquid guide hole. E-liquid can be transferred from the reservoir to the heating chamber, allowing it to be heated and atomized within the heating chamber, thus meeting the user's requirements for the amount of e-liquid they smoke.

[0004] However, in actual use, some air may pass through the heating chamber and enter the e-liquid storage chamber through the wicking hole, causing the e-liquid to deteriorate and thus reducing the user experience of the e-cigarette. Additionally, during transportation, some e-liquid in the storage chamber may also flow into the heating chamber through the wicking hole, resulting in e-liquid leakage. Utility Model Content

[0005] The main purpose of this invention is to propose an atomizer and electronic cigarette that aims to reduce the risk of e-liquid deterioration and leakage, and improve the user experience of the atomizer.

[0006] To achieve the above objectives, this utility model proposes an atomizer for storing and heating e-liquid. The atomizer includes an outer shell and an inner shell. The outer shell is fitted onto the outer wall of the inner shell. An oil storage cavity is formed between the outer shell and the inner shell. The inner shell is provided with a heating cavity. The side wall of the inner shell is provided with an oil guide hole communicating with the heating cavity.

[0007] The inner wall of the outer shell is provided with a stop portion, and the outer shell can drive the stop portion to move relative to the inner shell so that the atomizer has a working state and an idle state;

[0008] In the operating state, the stop portion is misaligned with the oil guide hole so that the heating chamber and the oil storage chamber are connected through the oil guide hole;

[0009] In the idle state, the stop portion covers the oil guide hole to isolate the heating chamber and the oil storage chamber.

[0010] In one embodiment, the outer shell includes a first pipe section and a second pipe section connected to each other. The inner diameter of the first pipe section is smaller than the inner diameter of the second pipe section. The first pipe section is movably sleeved on the outer wall of the inner shell. The inner wall surface of the first pipe section forms the stop portion. The inner wall of the second pipe section is at least partially spaced from the outer wall of the inner shell to form the oil storage cavity.

[0011] The first pipe segment drives the second pipe segment to move along the axial direction of the inner shell to form the usage state and the idle state.

[0012] In one embodiment, the inner shell includes a delivery pipe section and a heating pipe section connected to each other. The heating pipe section is provided with the heating chamber, and the side wall of the heating pipe section is provided with the oil guide hole. The delivery pipe section is provided with a smoke duct communicating with the heating chamber, so that the smoke generated by the heating chamber is transported along the smoke duct and inhaled by the user.

[0013] The first pipe section is movably sleeved on the outer wall of the heating pipe section and can move along the outer wall of the heating pipe section. The second pipe section and the conveying pipe section form the oil storage cavity.

[0014] In one embodiment, the outer wall of the heating tube segment is provided with a recess, and the inner wall of the first tube segment is provided with a protrusion corresponding to the recess;

[0015] In the idle state, the protrusion abuts against and is limited by the recess; in the use state, there is a gap between the protrusion and the recess.

[0016] In one embodiment, the atomizer further includes a base, the base being connected to one end of the heating tube section facing away from the delivery tube section, and a limiting groove being provided at one end of the first tube section facing the base, the limiting groove being arranged along the circumference of the first tube section;

[0017] In the usage state, the side wall of the base is in limiting contact with the limiting groove, and the side wall of the base is flush with the side wall of the first pipe section; in the idle state, there is a gap between the side wall of the base and the limiting groove.

[0018] In one embodiment, one of the first pipe section and the base is provided with a guide block, and the other is provided with a guide groove corresponding to the guide block;

[0019] The guide block is inserted into the guide groove and can move along the extension direction of the guide groove. In the use state, the end of the guide block is in limiting contact with the bottom of the guide groove.

[0020] In one embodiment, the atomizer further includes a connecting assembly disposed on the side of the base facing away from the heating tube segment. The connecting assembly includes a first connecting end, a second connecting end, and an insulating member. The second connecting end is sleeved on the outside of the first connecting end, and the insulating member is disposed between the first connecting end and the second connecting end. The first connecting end and the second connecting end are electrically connected to the heating element in the heating chamber, respectively.

[0021] In one embodiment, the outer wall of the heating tube segment is further provided with a plurality of first mounting grooves. Along the extension direction of the heating tube segment, the plurality of first mounting grooves are located on both sides of the oil guide hole. Each first mounting groove is provided with an elastic member, and the two sides of the elastic member abut against the inner wall of the first tube segment and the bottom wall of the first mounting groove, respectively.

[0022] In one embodiment, a third pipe section is provided on the side of the second pipe section opposite to the first pipe section. The third pipe section encloses and forms a mixing chamber. The third pipe section is provided with a suction port that connects the mixing chamber and the external environment. The delivery pipe section is partially inserted into the mixing chamber. The outer wall of the delivery pipe section abuts against the inner wall of the third pipe section, and the smoke duct is connected to the mixing chamber.

[0023] This utility model also proposes an electronic cigarette, which includes the atomizer described above.

[0024] The technical solution of this utility model utilizes the relative sliding of the outer shell and inner shell to move the stop relative to the oil guide hole, thereby achieving the connection or isolation between the oil storage chamber and the heating chamber. In the idle state, the stop covers the oil guide hole, isolating the oil storage chamber from the heating chamber, thus preventing external air from passing through the heating chamber and the oil guide hole into the oil storage chamber, preventing the e-liquid from deteriorating. In the use state, the outer shell is moved to misalign the stop with the oil guide hole, allowing the oil storage chamber and the heating chamber to connect through the oil guide hole, thus enabling normal use.

[0036] Electronic cigarettes consist of two parts: an atomizer and a frame. The atomizer stores e-liquid in a reservoir to provide sufficient fuel for subsequent use, and atomizes the e-liquid into vapor that can be inhaled through a heating chamber. The frame is used to provide electrical power.

[0037] In existing atomizers, the e-liquid reservoir and the heating chamber are not completely isolated; they are interconnected through an e-liquid guide hole. E-liquid can be transferred from the reservoir to the heating chamber, allowing it to be heated and atomized within the heating chamber, thus meeting the user's requirements for the amount of e-liquid they smoke.

[0038] However, in actual use, some air may pass through the heating chamber and enter the e-liquid storage chamber through the wicking hole, causing the e-liquid to deteriorate and thus reducing the user experience of the e-cigarette. Additionally, during transportation, some e-liquid in the storage chamber may also flow into the heating chamber through the wicking hole, resulting in e-liquid leakage.

[0039] The main purpose of this invention is to provide an atomizer 100 and an electronic cigarette, which aims to reduce the risk of e-liquid deterioration and leakage, and improve the user experience of the atomizer 100.

[0040] Please see Figures 1 to 4In one embodiment of this utility model, the atomizer 100 is used to store and heat e-liquid. The atomizer 100 includes an outer shell 1 and an inner shell 2. The outer shell 1 is fitted onto the outer wall of the inner shell 2, and an oil storage cavity 3 is formed between the outer shell 1 and the inner shell 2. The inner shell 2 is provided with a heating cavity 221, and the side wall of the inner shell 2 is provided with an oil guide hole 222 communicating with the heating cavity 221. The inner wall of the outer shell 1 is provided with a stop portion 111, which can drive the outer shell 1 to move relative to the inner shell 2, so that the atomizer 100 has a working state and an idle state. In the working state, the stop portion 111 is misaligned with the oil guide hole 222, so that the heating cavity 221 and the oil storage cavity 3 are connected through the oil guide hole 222. In the idle state, the stop portion 111 covers the oil guide hole 222, so that the heating cavity 221 and the oil storage cavity 3 are isolated.

[0041] In this embodiment, the atomizer 100 includes an outer shell 1 and an inner shell 2. A heating chamber 221 is disposed inside the inner shell 2. The enclosed space formed between the outer shell 1 and the inner shell 2 is the e-liquid storage chamber 3, used to store e-liquid. The wicking hole 222 on the side wall of the inner shell 2 connects the e-liquid storage chamber 3 and the heating chamber 221. A stop 111 is disposed on the inner wall of the outer shell 1. As the outer shell 1 moves, the positional relationship between the stop 111 and the wicking hole 222 changes. When the atomizer 100 is idle, the stop 111 can cover the wicking hole 222, forming a barrier to prevent external air from entering the e-liquid storage chamber 3 through the heating chamber 221 and the wicking hole 222, thus preventing e-liquid deterioration. It also prevents e-liquid from leaking from the e-liquid storage chamber 3 into the heating chamber 221 through the wicking hole 222 during transportation. When the atomizer 100 is switched to the operating state, the outer shell 1 moves the stop part 111, causing the stop part 111 to misalign with the oil guide hole 222. At this time, the e-liquid in the oil storage chamber 3 can smoothly enter the heating chamber 221 through the oil guide hole 222, providing raw materials for the subsequent atomization process. It is understandable that this solution achieves the change in the connection state between the oil storage chamber 3 and the heating chamber 221 through simple mechanical movement, solving the problems of e-liquid deterioration and leakage existing in the prior art.

[0042] In one implementation, please refer to Figure 1 and Figure 2 The outer casing 1 includes a first pipe section 11 and a second pipe section 12 connected to each other. The inner diameter of the first pipe section 11 is smaller than the inner diameter of the second pipe section 12. The first pipe section 11 is movably fitted onto the outer wall of the inner casing 2. A stop portion 111 is formed on the inner wall surface of the first pipe section 11. At least part of the inner wall of the second pipe section 12 is spaced from the outer wall of the inner casing 2 to form an oil storage cavity 3. The first pipe section 11 drives the second pipe section 12 to move along the axial direction of the inner casing 2 to form a working state and an idle state.

[0043] The outer shell 1 includes a first tube segment 11 and a second tube segment 12. The inner diameter of the first tube segment 11 is relatively small and it is directly fitted onto the inner shell 2, providing a structural basis for the connection between the outer shell 1 and the inner shell 2. Furthermore, the cooperation between the first tube segment 11 and the inner shell 2 also serves as a limiting function, allowing the first shell to move only along the outer wall of the inner shell 2. A certain gap is maintained between the inner wall of the second tube segment 12 and the outer wall of the inner shell 2, forming an oil storage chamber 3 for storing e-liquid. A stop portion 111 is formed on the inner wall surface of the first tube segment 11. When the first tube segment 11 moves the second tube segment 12 along the axial direction of the inner shell 2 under the action of external force, the position of the entire outer shell 1 changes, thereby altering the relative positional relationship between the stop portion 111 and the oil guide hole 222, allowing the atomizer 100 to switch between an active state and an idle state.

[0044] Optionally, the first pipe section 11 and the second pipe section 12 can be integrally formed, or they can be fixedly connected to each other by means of threaded connection or snap-fit ​​connection. At the same time, the cross-sectional shape of the oil storage cavity 3 can be circular, elliptical or other irregular shape, as long as it can ensure sufficient space to store e-liquid and does not hinder the movement of the outer shell 1.

[0045] In one implementation, please refer to Figure 2 and Figure 4 The inner shell 2 includes a conveying pipe section 21 and a heating pipe section 22 connected to each other. The heating pipe section 22 has a heating chamber 221 inside, and the side wall of the heating pipe section 22 has an oil guide hole 222. The conveying pipe section 21 has a smoke duct 211 communicating with the heating chamber 221, so that the smoke generated by the heating chamber 221 is transported along the smoke duct 211 and inhaled by the user. The first pipe section 11 is movably sleeved on the outer wall of the heating pipe section 22 and can move along the outer wall of the heating pipe section 22. An oil storage chamber 3 is formed between the second pipe section 12 and the conveying pipe section 21.

[0046] In this embodiment, the inner shell 2 includes a delivery pipe section 21 and a heating pipe section 22 connected to each other. A heating chamber 221 is provided inside the heating pipe section 22, and an oil guide hole 222 is formed on the side wall of the heating pipe section 22. A smoke channel 211 is formed inside the delivery pipe section 21, which communicates with the heating chamber 221 to transport atomized smoke for inhalation by the user. A first pipe section 11 is fitted onto the outer wall of the heating pipe section 22 and can move along the outer wall of the heating pipe section 22. An oil storage chamber 3 is formed between the second pipe section 12 and the delivery pipe section 21.

[0047] Optionally, the conveying pipe section 21 and the heating pipe section 22 can be connected by welding, bonding, or integral molding. For example, if the conveying pipe section 21 and the heating pipe section 22 are made of metal, they can be connected together by laser welding. If the conveying pipe section 21 and the heating pipe section 22 are made of plastic, they can be bonded using suitable adhesive. Alternatively, the conveying pipe section 21 and the heating pipe section 22 can be integrally molded using injection molding to ensure the sealing and firmness of the connection.

[0048] Optionally, the shape of the wicking hole 222 can be circular, square, or strip-shaped. A strip-shaped hole allows the e-liquid to flow out evenly within a certain width range, while a circular hole makes the e-liquid flow out relatively concentrated and faster. Technicians can adjust the shape and size of the wicking hole 222 according to the specific e-liquid flow requirements.

[0049] In one implementation, please refer to Figure 2 and Figure 4 The outer wall of the heating tube section 22 is provided with a recess 223, and the inner wall of the first tube section 11 is provided with a protrusion 112 corresponding to the recess 223. In the idle state, the protrusion 112 abuts against the recess 223 and is limited in place. In the use state, there is a gap between the protrusion 112 and the recess 223.

[0050] In this embodiment, a recess 223 is provided on the outer wall of the heating tube segment 22, while a protrusion 112 is provided on the inner wall of the first tube segment 11 that cooperates with it. When the atomizer 100 is in an idle state, the protrusion 112 and the recess 223 are in close contact to prevent the outer shell 1 from moving unnecessarily under external force interference, ensuring that the stop part 111 can stably cover the oil guide hole 222 and maintain the isolation state between the oil storage chamber 3 and the heating chamber 221. When the atomizer 100 needs to be switched to the use state, as the outer shell 1 moves, the protrusion 112 and the recess 223 separate from each other, so that the outer shell 1 can move along a predetermined direction until the stop part 111 and the oil guide hole 222 are misaligned, realizing the connection between the oil storage chamber 3 and the heating chamber 221.

[0051] Alternatively, a protrusion 112 can be provided on the outer wall of the heating tube section 22, and a recess 223 can be provided on the inner wall of the first tube section 11. Both can also limit the movement of the outer shell 1.

[0052] In one implementation, please refer to Figure 1 and Figure 3The atomizer 100 also includes a base 4, which is connected to the end of the heating tube section 22 facing away from the delivery tube section 21. A limiting groove 113 is provided at the end of the first tube section 11 facing the base 4, and the limiting groove 113 is arranged circumferentially along the first tube section 11. In the use state, the side wall of the base 4 is in limiting contact with the limiting groove 113, and the side wall of the base 4 is flush with the side wall of the first tube section 11; in the idle state, there is a gap between the side wall of the base 4 and the limiting groove 113.

[0053] In this embodiment, the base 4 is installed at the end of the heating tube section 22 facing away from the delivery tube section 21, serving as a support and limiting element. The end of the first tube section 11 facing the base 4 has a limiting groove 113 along its circumferential direction. When the atomizer 100 is in use, the side wall of the base 4 abuts tightly against the limiting groove 113, forming a stable limiting structure to prevent excessive movement of the outer shell 1 during use, ensuring the relative position stability between the components of the atomizer 100. Simultaneously, the side wall of the base 4 is flush with the side wall of the first tube section 11, making the atomizer 100 appear neater and more aesthetically pleasing. When the atomizer 100 moves from the use state to the idle state, the side wall of the base 4 gradually separates from the limiting groove 113.

[0054] Understandably, the limiting of the recess 223 and the protrusion 112, as well as the limiting of the side wall of the base 4 and the limiting groove 113, can prevent the outer shell 1 from moving excessively during use, thereby ensuring the accuracy of the moving position.

[0055] Optionally, the connection between the base 4 and the heating tube section 22 can be a threaded connection, a snap-fit ​​connection, or an adhesive connection. Optionally, the depth and width of the limiting groove 113 can also be adjusted according to actual needs, as long as it ensures that the side wall of the base 4 and the limiting groove 113 are in tight contact during use, and do not hinder the sliding of the outer shell. Meanwhile, to enhance sealing, a sealing ring can also be installed at the connection between the base 4 and the heating tube section 22 to prevent flue gas leakage.

[0056] In one implementation, please refer to Figure 1 and Figure 3 One of the first pipe section 11 and the base 4 is provided with a guide block 114, and the other is provided with a guide groove 41 corresponding to the guide block 114. The guide block 114 is inserted into the guide groove 41 and can move along the extension direction of the guide groove 41. In the use state, the end of the guide block 114 is limited and abuts against the bottom of the guide groove 41.

[0057] In this embodiment, the guide block 114 and the guide groove 41 are respectively disposed on the first tube section 11 and the base 4. The guide block 114 is inserted into the guide groove 41 and can move along the extension direction of the guide groove 41. When the atomizer 100 is in use, the end of the guide block 114 is in close contact with the bottom of the guide groove 41. When the atomizer 100 changes from the use state to the idle state, the side wall of the guide block 114 is in limiting contact with the side wall of the guide groove 41 to prevent the outer shell 1 from rotating relative to the inner shell 2.

[0058] Understandably, in order to ensure stability throughout the entire movement process, the guide groove 41 needs to be long enough so that the guide block 114 will not separate from the guide groove 41 during the movement.

[0059] In one implementation, please refer to Figure 1 and Figure 2 The atomizer 100 also includes a connecting component 5, which is located on the side of the base 4 facing away from the heating tube section 22. The connecting component 5 includes a first connecting end 51, a second connecting end 52, and an insulating member 53. The second connecting end 52 is sleeved on the outside of the first connecting end 51, and the insulating member 53 is located between the first connecting end 51 and the second connecting end 52. The first connecting end 51 and the second connecting end 52 are electrically connected to the heating element in the heating chamber 221, respectively.

[0060] In this embodiment, the connecting component 5 includes a first connecting end 51, a second connecting end 52, and an insulating member 53. The second connecting end 52 is sleeved on the outside of the first connecting end 51, forming a coaxial electrical connection structure. The insulating member 53 is disposed between the first connecting end 51 and the second connecting end 52 to prevent short circuits between the first connecting end 51 and the second connecting end 52. It can be understood that the atomizer 100 can not only be connected to other components via the second connecting end 52, but the first connecting end 51 and the second connecting end 52 are also electrically connected to the heating element in the heating chamber 221. When the frame of the electronic cigarette is connected to the connecting component 5, electrical energy can be transmitted to the heating element through the connecting component 5, providing energy for the atomization process of the e-liquid. The first connecting end 51 and the second connecting end 52 can be made of metal, such as copper alloy or gold-plated steel, to ensure good conductivity. The insulating member 53 can be made of insulating materials such as ceramic or plastic.

[0061] In one implementation, please refer to Figure 2 and Figure 4 The outer wall of the heating tube section 22 is also provided with a plurality of first mounting grooves 224. Along the extension direction of the heating tube section 22, the plurality of first mounting grooves 224 are located on both sides of the oil guide hole 222. Each first mounting groove 224 is provided with an elastic element 225. The two sides of the elastic element 225 abut against the inner wall of the first tube section 11 and the bottom wall of the first mounting groove 224, respectively.

[0062] In this embodiment, multiple first mounting grooves 224 are provided on both sides of the oil guide hole 222. An elastic element 225 is provided within each first mounting groove 224, and both sides of the elastic element 225 are in close contact with the inner wall of the first pipe section 11 and the bottom wall of the first mounting groove 224, respectively. It can be understood that a gap exists between the oil guide hole 222 and the inner wall of the first pipe section 11, and the elastic elements 225 on both sides of the oil guide hole 222, the inner wall of the first pipe section 11, and the bottom wall of the first mounting groove 224 cooperate to form a stop portion 111. When the atomizer 100 is idle, at least one elastic element 225 on both sides of the oil guide hole 222 is in contact with the inner wall of the first tube section 11. When the atomizer 100 is in use, the elastic element 225 on the side of the oil guide hole 222 near the oil storage chamber 3 is not in contact with the inner wall of the first tube section 11, so that the e-liquid can smoothly pass through the oil guide hole 222 into the heating chamber 221, ensuring the normal use of the atomizer 100.

[0063] Optionally, the elastic element 225 can be made of a material with good elasticity and corrosion resistance, such as a rubber block or a silicone pad. Furthermore, the elastic coefficient of the elastic element 225 can be selected according to actual needs, ensuring that it provides sufficient abutment force to achieve a seal in the idle state, while also ensuring that the abutment can be smoothly released in the use state, allowing the outer casing 1 to move.

[0064] In one implementation, please refer to Figure 2 and Figure 4 The outer diameter of the heating pipe section 22 is larger than the outer diameter of the conveying pipe section 21. The end of the heating pipe section 22 facing the conveying pipe section 21 is provided with a second mounting groove 226, and the conveying pipe section 21 is inserted into the second mounting groove 226.

[0065] In this embodiment, the outer diameter of the heating pipe section 22 is larger than the outer diameter of the conveying pipe section 21. The conveying pipe section 21 is inserted into the second mounting groove 226 of the heating pipe section 22, and the outer wall of the conveying pipe section 21 is limited and abutted against the inner wall of the second mounting groove 226. This arrangement not only facilitates installation but also ensures the sealing of the connection and prevents flue gas leakage.

[0066] Optionally, the connection between the delivery pipe section 21 and the second mounting groove 226 can be achieved by bonding, welding, or snap-fitting.

[0067] In one implementation, please refer to Figure 1 and Figure 2 The second pipe section 12 is provided with a third pipe section 13 on the side opposite to the first pipe section 11. The third pipe section 13 encloses and forms a mixing chamber 131. The third pipe section 13 is provided with a suction port 132 that connects the mixing chamber 131 and the external environment. The delivery pipe section 21 is partially inserted into the mixing chamber 131. The outer wall of the delivery pipe section 21 abuts against the inner wall of the third pipe section 13, and the smoke duct 211 is connected to the mixing chamber 131.

[0068] In this embodiment, the third pipe segment 13 is installed on the side of the second pipe segment 12 facing away from the first pipe segment 11, and has a mixing chamber 131. The delivery pipe segment 21 is partially inserted into the mixing chamber 131, and the outer wall of the delivery pipe segment 21 abuts against the inner wall of the third pipe segment 13.
