[0028] Currently, for the oil injection type electronic atomizers on the market, after injecting oil with an oil injection needle, it is necessary to press the mouthpiece or block the oil injection hole with a rubber plug, and it is necessary to press the mouthpiece or the rubber plug tightly before use. The existing oil injection structure of the electronic atomizer affects the oil injection efficiency, and the operation is complex, resulting in a poor user experience.

The first channel 111 and the second channel 131 extend coaxially.

[0031] The oil injection structure 10 further includes a plugging assembly 14. The plugging assembly 14 is used to move in the receiving groove 121 to switch between a first state and a second state. In the first state, the plugging assembly 14 is spaced apart from the bottom wall of the receiving groove 121, and the receiving groove 121 communicates the first channel 111 and the second channel 131. In the second state, the plugging assembly 14 abuts against the bottom wall of the receiving groove 121, and the plugging assembly 14 plugs the second channel 131.

[0032] Specifically, Figure 1 is a cross-sectional view of the oil injection structure 10 in the second state, Figure 2 is a cross-sectional view of the oil injection structure 10 in the first state. The oil injection operation is performed in the first state. The first channel 111 of the oil injection structure 10 is farther from the ground than the second channel 131. The oil injection operation is completed in the second state. The first channel 111 of the oil injection structure 10 is farther from the ground than the second channel 131.

[0033] The cross-sectional shapes of the first channel 111, the second channel 131, and the receiving groove 121 in their respective axial directions can be circular, elliptical, rectangular, etc., without limitation.

[0034] The oil injection mechanism of the present utility model is provided with a first channel 111, a second channel 131, a receiving groove 121 and a plugging assembly 14. The plugging assembly 14 moves in the receiving groove 121 to switch between a first state and a second state. The first state is the oil injection state, and the receiving groove 121 communicates with the first channel 111 and the second channel 131, so that oil and the like can enter the oil storage cavity 211 from the outside. The second state is the plugging state, and the plugging assembly 14 abuts against the bottom wall of the receiving groove 121, so that the second channel 131 and the second channel 131 are disconnected, and oil cannot enter the oil storage cavity 211 through the second channel 131. The oil injection mechanism of the present utility model does not need to be provided with an additional suction nozzle or a rubber plug to block the oil injection channel. After the oil injection is completed, the plugging assembly 14 automatically plugs the second channel 131 to complete oil sealing, without the need for the user to manually seal the oil. Therefore, the operation of this oil injection mechanism is simple, the oil injection efficiency is high, and the user experience is good.

[0035] For reference Figure 3 and Figure 4 In one embodiment, the oil injection structure 10 includes a first pipe 11, a second pipe 12 and a mounting seat 13. The mounting seat 13 is connected to one end of the first pipe 11. One end of the second pipe 12 is connected to the connection part of the first pipe 11 and the mounting seat 13. The first channel 111 is arranged in the first pipe 11. The receiving groove 121 is arranged in the first pipe 11, the second pipe 12 and the mounting seat 13. The second channel 131 is arranged in the mounting seat 13. The receiving groove 121 has an inclined angle with the first channel 111.

[0036] The first pipe 11, the second pipe 12 and the mounting seat 13 are made of anti-corrosion materials with high structural strength, specifically, they can be metal materials, high-strength plastics, ceramics, etc. Metal materials such as aluminum, aluminum alloy, magnesium alloy, iron and iron alloy, etc. are not limited.

[0037] The mounting seat 13 can be a cube, a sphere, etc., without limitation.

[0038] The first pipe 11, the second pipe 12 and the mounting seat 13 can be an integral structure, that is, the first pipe 11, the second pipe 12 and the mounting seat 13 are an integral structure made by an integral molding process. The integral molding process can specifically be stamping, casting, etc., without limitation. The first pipe 11, the second pipe 12 and the mounting seat 13 can also be a split structure, and the first pipe 11, the second pipe 12 and the mounting seat 13 can be connected and fixed by welding, bonding, clamping, screwing, etc.

[0039] The first pipe 11, the second pipe 12 and the mounting seat 13 are provided to realize the first channel 111, the second channel 131 and the receiving groove 121. The inclined angle between the receiving groove 121 and the first channel 111 enables the plugging assembly 14 to switch between the first state and the second state.

[0040] For reference Figure 4, In one embodiment, the receiving groove 121 and the first channel 111 form an included angle a, satisfying: 20° ≤ a ≤ 50°. Optionally, a can be 20°, 30°, 40°, 50°, etc., without limitation.

[0041] The central axis of the first channel 111 is the first axis a1, and the central axis of the receiving groove 121 is the second axis a2.

[0042] Specifically, the included angle a between the receiving groove 121 and the first channel 111 is the included angle between the first axis a1 and the second axis a2.

[0043] When a < 20°, the included angle a between the receiving groove 121 and the first channel 111 is too small, and during the process of switching from the second state to the first state, the blocking component 14 is not easy to move away from the bottom wall of the receiving groove 121; when a > 50°, the included angle a between the receiving groove 121 and the first channel 111 is too small, and during the process of switching from the first state to the second state, the side wall of the receiving groove 121 has a large limiting effect on the blocking component 14, and the blocking component 14 is not easy to abut against the bottom wall of the receiving groove 121, and it is not easy to achieve the blocking of the second channel 131; when 20° ≤ a ≤ 50°, the degree of the included angle a between the receiving groove 121 and the first channel 111 is appropriate, which is convenient for the oil injection mechanism to switch between the first state and the second state.

[0044] For reference Figure 3 and Figure 4 , In one embodiment, the blocking component 14 includes a ball member 141, an elastic member 142, and a cover body 143. The cover body 143 is disposed at the end of the second pipe 12 away from the mounting seat 13. The cover body 143 is used to close the second pipe 12. One end of the elastic member 142 abuts against the cover body 143, and the other end of the elastic member 142 abuts against the ball member 141. The elastic member 142 is always in a compressed state. In the second state, the ball member 141 blocks the second channel 131.

[0045] The manufacturing method of the ball member 141 can be forging, casting, precision machining, etc., without limitation. The ball member 141 can be a steel ball, an aluminum alloy ball, etc., without limitation.

[0046] The connection method between the cover body 143 and the second pipe 12 can be screwed connection, welding, bonding, snap connection, etc., without limitation. The material of the cover body 143 can be the same as or different from that of the second pipe 12, without limitation. Optionally, the material of the cover body 143 is plastic, and the material of the second pipe 12 is metal.

[0047] Optionally, the cover body 143 includes a cover plate 1431 and an extension portion 1432. The cover plate 1431 covers the end of the second pipe 12, and the extension portion 1432 is disposed on the end face of the cover plate 1431 facing the second pipe 12, and the extension portion 1432 extends into the interior of the second pipe 12.

[0048] The elastic member 142 can be a spring, an elastic pad, etc., without limitation.

[0049] The cover 143 is provided to prevent e-liquid, etc. from overflowing from the second tube 12 to the refueling structure 10 and contaminating the remaining components of the electronic atomizer 100. During the process of switching from the first state to the second state and in the second state, the elastic member 142 is used to push the spherical member 141 to move away from the cover 143 to block the second channel 131 and disconnect the refueling structure 10 from the outside; during the process of switching between the first state and the second state to the first state, the spherical member 141 applies pressure to the elastic member 142, compresses the elastic member 142 and provides space to accommodate the spherical member 141, so that the second channel 131, the receiving groove 121, and the first channel 111 are connected to facilitate the refueling operation.

[0050] In one embodiment, the bottom wall of the receiving groove 121 is an arc surface, and the radius of the arc surface is the same as the radius of the spherical member 141.

[0051] There can be two arc surfaces, and the two arc surfaces are arranged oppositely with respect to the central axis of the receiving groove 121.

[0052] The bottom wall of the receiving groove 121 being an arc surface with the same radius as the spherical member 141 enables the spherical member 141 to closely adhere to the bottom wall of the receiving groove 121, preventing e-liquid from flowing out through the gap between the spherical member 141 and the receiving groove 121 in the second state.

[0053] For reference Figure 3 and Figure 4 , in one embodiment, the mounting base 13 has a mounting groove 132, the mounting groove 132 communicates with the bottom wall of the receiving groove 121, the refueling structure 10 further includes a silica gel member 15, at least part of the silica gel member 15 is received in the mounting groove 132, and the silica gel member 15 surrounds the second channel 131.

[0054] The silica gel member 15 can be completely received in the mounting groove 132. The silica gel member 15 can be divided into a first part 151 and a second part 152. The first part 151 is received in the mounting groove 132, the second part 152 is in close contact with the end face of the mounting base 13, and the second part 152 extends along the direction away from the first tube 11 to the housing of the electronic atomizer 100. The second part 152 surrounds a third channel 153, and the third channel 153 extends coaxially with the second channel 131.

[0055] Providing the silica gel member 15 can improve the leak prevention property of the refueling structure 10, prevent e-liquid from seeping out. At the same time, the silica gel member 15 can reduce the collision between the spherical member 141 and the mounting groove 132 and improve the service life of the refueling structure 10.

[0056] In one embodiment, the end face of the silica gel member 15 close to the first channel 111 is smoothly connected to the bottom wall of the receiving groove 121.

[0057] Specifically, the bottom wall of the receiving groove 121 is an arc surface, and the end surface of the silicone member 15 close to the first channel 111 is correspondingly set as an arc surface.

[0058] In the second state, the ball member 141 abuts against the bottom wall of the receiving groove 121 and at the same time abuts against the end surface of the silicone member 15 close to the first channel 111. The end surface of the silicone member 15 close to the first channel 111 is smoothly connected to the bottom wall of the receiving groove 121, that is, the end surface of the silicone member 15 close to the first channel 111 is smoothly connected to the ball member 141, which can reduce the gap between the ball member 141 and the silicone member 15 and avoid the accumulation of oil liquid in the gap between the ball member 141 and the silicone member 15 in the second state.

[0059] For reference Figure 4 In one embodiment, the installation groove 132 includes a first groove 1321 and a second groove 1322 that are connected and communicate with each other. The radial dimension of the first groove 1321 is larger than the radial dimension of the second groove 1322. The second groove 1322 communicates with the receiving groove 121. The silicone member 15 is received in the first groove 1321 and the second groove 1322, and the diameter of the ball member 141 is larger than the inner diameter of the second groove 1322.

[0060] The radial dimension of the first groove 1321 is larger than the radial dimension of the second groove 1322, that is, the second groove 1322 penetrates the bottom wall of the first groove 1321, so that the second groove 1322 and the first groove 1321 cooperate to form a clamping surface 1323. In the second state, the ball member 141 exerts a pressure on the silicone member 15 under the influence of gravity, and the clamping surface 1323 formed by the first groove 1321 and the second groove 1322 can prevent the silicone member 15 from being forced out of the installation groove 132.

[0061] For reference Figure 3 and Figure 4 In one embodiment, a receiving groove 112 is provided on the outer side wall of the end of the first tube 11 away from the mounting seat 13. The oil injection structure 10 further includes a sealing member 16, and the sealing member 16 is received in the receiving groove 112.

[0064] Setting the sealing member 16 can enhance the sealing performance of the oil injection structure 10 inside the electronic atomizer 100 and avoid the leakage of e-liquid.

[0065] For reference Figure 1 and Figure 2, the present utility model provides an electronic atomizer 100, which includes a main body 20 and the oil injection structure 10 described in any one of the foregoing various embodiments.

[0067] The oil injection hole 22 is correspondingly arranged with the shape of the second channel 131. Optionally, the cross-sections of the second channel 131 and the oil injection hole 22 in the radial direction are circles with the same diameter.

[0068] One end of the silica gel part 15 away from the first channel 111 abuts against the inner wall of the main body 20.

[0069] The electronic atomizer 100 further includes an atomization core 24 and a connecting rod 25. The atomization core 24 is received in the oil storage cavity 211. The connecting rod 25 is connected to the atomization core 24 and extends to the mouthpiece assembly 23 to be connected to the mouthpiece assembly 23. The atomization core 24 is prepared from porous ceramics with high porosity so that the atomized gas can flow smoothly. An oil inlet hole 241 is formed on the atomization core 24 and the oil inlet hole 241 communicates with the oil storage cavity 211. The oil liquid in the oil storage cavity 211 enters the interior of the atomization core 24 from the liquid inlet hole and is heated and atomized. The atomized e-liquid is transmitted to the mouthpiece assembly 23 through the interior of the connecting rod 25.

[0070] Optionally, there are multiple oil inlet holes 241, and the multiple liquid inlet holes are arranged at intervals on the atomization core 24. The multiple oil inlet holes 241 can be arranged at intervals in the circumferential direction and / or the axial direction of the atomization core 24. They can be arranged in an array or unevenly, without limitation. The oil inlet hole 241 can also be one. The shape of the oil inlet hole 241 can be circular, oval, rectangular, without limitation.

[0071] The main body 20 further has a battery cavity. The battery cavity is arranged on the side of the oil injection mechanism facing away from the oil storage cavity 211.

The nozzle housing 231 is connected to the oil storage housing 21, and the connection method can be welding, screwing, clamping, etc., without limitation. The nozzle housing 231 is made of a material with high structural strength, specifically, it can be a metal material, a high-strength plastic, a ceramic, etc. Metal materials such as aluminum, aluminum alloy, magnesium alloy, iron and iron alloy, etc., without limitation. The size of the nozzle housing 231 gradually decreases in the direction away from the oil injection hole 22, and the projection of the nozzle housing 231 in the height direction of the electronic atomizer 100 can be cap-shaped. The nozzle silica gel 232 is disposed between the nozzle housing 231 and the oil storage housing 21 to seal the oil storage cavity 211 and prevent leakage of liquids such as e-liquid. The nozzle silica gel 232 can also be disposed in the gap inside the nozzle housing 231, which can play a role in supporting the strength of the nozzle housing 231. The nozzle silica gel 232 can help the nozzle housing 231 to enclose and form an air outlet channel.

[0073] The electronic atomizer 100 further includes an oil injection tube 27. In the first state, the oil injection tube 27 sequentially passes through the oil injection hole 22, the second channel 131, the receiving groove 121, and the first channel 111. The e-liquid enters the oil storage cavity 211 from the pipeline inside the oil injection tube 27. The oil injection tube 27 abuts against the spherical member 141 so that the spherical member 141 compresses the elastic member 142 and the spherical member 141 moves in the receiving groove 121 in the direction close to the cover body 143. In the second state, the oil injection tube 27 withdraws from the inside of the main body 20, and the elastic member 142 pushes the spherical member 141 to move in the direction away from the cover body 143 to block the second channel 131.

[0074] When the user refuels the electronic atomizer 100 of the present utility model, the oil injection tube 27 is used to push open the spherical member 141 for refueling operation. After the refueling operation is completed, the elastic member 142 ejects the spherical member 141 to block the oil injection hole 22 to prevent oil leakage.
