[0025] Such as Figures 1 to 6As shown in the figure, a preferred embodiment of the hand-held atomizer of the present utility model includes an oil storage bottle 1, an oil delivery pipe 2, an atomization core 3 and a first seal 4. The lower end of the oil delivery pipe 2 communicates with the bottle cavity of the oil storage bottle 1. An oil outlet hole 21 is provided on the outer side of the upper end of the oil delivery pipe 2. The atomization core 3 is sleeved on the outer side of the upper end of the oil delivery pipe 2 and covers the oil outlet hole 21. The first seal is plugged at a position in the pipe cavity of the oil delivery pipe 2 above the oil outlet hole 21. The first seal 4 is provided with a first oil-blocking and air-exchanging channel 411 that communicates the pipe cavity of the oil delivery pipe 2 with the outside. When in use, the hand-held atomizer is turned over so that the atomization liquid in the oil storage bottle 1 flows into the oil delivery pipe 2, and then flows into the atomization core 3 through the oil outlet hole 21. The first oil-blocking and air-exchanging channel 411 can play a role in ventilation, ensuring that the atomization liquid can quickly flow into the atomization core 3. Therefore, the hand-held atomizer of the present utility model can efficiently introduce the atomization liquid into the atomization core 3, meeting the user's demand for high-concentration smoke. Moreover, the aperture of the first oil-blocking and air-exchanging channel 411 is small, which can prevent the atomization liquid from flowing out while ventilating, ensuring the sealing of the atomization liquid by the hand-held atomizer.

[0026] Among them, the oil storage bottle 1 is detachably connected to the oil delivery pipe 2. The first seal 4 includes a push-pull rod 41 and a piston 42 that is slidably sealed in the pipe cavity. The upper end of the push-pull rod 41 is inserted into the pipe cavity and fixedly connected to the piston 42. The lower end of the push-pull rod 41 extends outside the pipe cavity. The first oil-blocking and air-exchanging channel 411 is provided in the push-pull rod 41 or the piston 42. Specifically, the oil storage bottle 1 is detachably connected to the oil delivery pipe 2. After the atomization liquid in the oil storage bottle 1 is used up, or when it is necessary to replace the atomization liquid with a different flavor, the old oil storage bottle 1 can be removed and a new oil storage bottle 1 can be installed. When the oil storage bottle 1 is not installed, the push-pull rod 41 is pulled downward until the piston 42 is pulled below the oil outlet hole 21. At this time, the piston 42 can prevent the residual atomization liquid in the atomization core 3 from flowing downward out of the oil delivery pipe 2.

[0027] In this embodiment, the piston 42 is a ring body, and the piston 42 is fixedly sleeved on the outer side of the upper end of the push rod 41. The first oil-blocking and air-exchanging channel 411 is arranged in the push rod 41. Specifically, the first oil-blocking and air-exchanging channel 411 is a groove body arranged on the outer side of the push rod 41. In other embodiments of the present invention, the first oil-blocking and air-exchanging channel 411 can be arranged inside the push rod 41. For example, the first oil-blocking and air-exchanging channel 411 is arranged in an L shape. The L-shaped first oil-blocking and air-exchanging channel 411 includes a vertical section arranged along the axial direction of the push rod 41 and a horizontal section arranged along the radial direction of the push rod 41. The horizontal section and the vertical section are communicated, and the horizontal section is located below the piston 42. In this embodiment, arranging the first oil-blocking and air-exchanging channel 411 on the outer side of the push rod 41 is convenient for processing, and two first oil-blocking and air-exchanging channels 411 are symmetrically arranged. In other embodiments of the present invention, multiple first oil-blocking and air-exchanging channels 411 can be arranged, and the multiple first oil-blocking and air-exchanging channels 411 are arranged around the axial direction of the push rod 41. In this embodiment, the cross-sectional area of the first oil-blocking and air-exchanging channel 411 near the oil end is greater than or equal to 0.01 mm 2 and less than or equal to 0.08 mm 2 . Setting the cross-sectional area of the first oil-blocking and air-exchanging channel 411 to 0.01 mm 2 is beneficial to blocking the outflow of oil, and setting the cross-sectional area of the first oil-blocking and air-exchanging channel 411 to 0.08 mm 2 is beneficial to ventilation. In this embodiment, the cross-sectional area of the first oil-blocking and air-exchanging channel 411 is set to 0.04 mm 2 . Among them, the cross-section of the first oil-blocking and air-exchanging channel 411 in the length direction of the first oil-blocking and air-exchanging channel can be a regular cross-section or an irregular cross-section. When a regular cross-section is adopted, the overall cross-sectional area of the first oil-blocking and air-exchanging channel is greater than or equal to 0.01 mm 2 and less than or equal to 0.08 mm 2 . When an irregular cross-section is adopted, the cross-sectional area of the end of the first oil-blocking and air-exchanging channel near the oil end is greater than or equal to 0.01 mm 2 and less than or equal to 0.08 mm 2 , and the cross-sectional area of the end far from the oil end can be set larger. Among them, the cross-sectional shape of the first oil-blocking and air-exchanging channel 411 can be a square hole, a circular hole, an arc hole, etc.

[0028] In this embodiment, a pushing structure 121 for pushing the push rod 41 upward is provided in the bottle cavity of the oil storage bottle 1. Specifically, when installing the oil storage bottle 1, the lower end of the oil delivery pipe 2 and the push rod 41 protruding outside the oil delivery pipe 2 need to be inserted into the oil storage bottle 1. At this time, there is a relative up-and-down movement between the oil storage bottle 1 and the push rod 41. By setting the pushing structure 121 in the bottle cavity of the oil storage bottle 1, when installing the oil storage bottle 1, the pushing structure 121 pushes the push rod 41 upward, and can push the piston 42 above the oil outlet hole 21. At this time, the oil outlet hole 21 is communicated with the bottle cavity of the oil storage bottle 1, and the piston 42 plays a role in preventing the atomized liquid from flowing out of the upper end of the oil delivery pipe 2. Specifically, as Figure 4 shown, the oil storage bottle 1 includes a bottle body and a cover body. The bottle body and the cover body are hermetically clamped, and the bottle mouth is provided on the cover body. The pushing structure 121 includes a plurality of columnar bodies fixed to the lower end of the cover body and extending downward to the middle of the bottle body. The columnar bodies are arranged at intervals around the axial direction of the bottle mouth. The lower ends of the columnar bodies are fixedly connected through a transverse connecting portion. The gap between two adjacent columnar bodies can allow the atomized liquid to flow into the bottle mouth and then into the oil delivery pipe. In this embodiment, the oil outlet hole is a groove-shaped hole extending parallel to the axial direction of the oil delivery pipe, and the length of the groove-shaped hole is less than the height of the atomizing core, so that the atomizing core can completely cover the groove-shaped hole. There are a plurality of oil delivery holes, and the plurality of oil delivery holes are arranged at intervals around the axial direction of the oil delivery pipe.

[0029] In this embodiment, the handheld atomizer includes a second sealing member. The second sealing member is arranged in the lumen and above the first sealing member 4. A second oil-blocking and air-exchanging channel 5211 communicating the lumen with the outside is provided in the second sealing member. After removing the oil storage bottle 1, when the piston 42 is moved below the oil outlet hole 21 through the push rod 41, the piston 42 plays a role in blocking the atomized liquid in the atomizing core 3 from flowing out of the lower end of the oil delivery pipe 2, and the second sealing member plays a role in blocking the atomized liquid in the atomizing core 3 from flowing out of the upper end of the oil delivery pipe 2; after installing the oil storage bottle 1, the push rod 41 pushes the piston 42 above the oil outlet hole 21. At this time, the piston 42 and the second sealing member jointly play a role in blocking the oil fume in the atomizing core 3 from flowing out of the upper end of the oil delivery pipe 2. Moreover, during the process of the push rod 41 pushing the piston 42 upward, the second oil-blocking and air-exchanging channel 5211 can play a role in exhausting the air between the piston 42 and the second sealing member, ensuring that the piston 42 can be smoothly pushed upward.

[0030] To improve the sealing effect of the piston 42 and the second sealing member on the atomized liquid, in this embodiment, the second oil-blocking and air-exchanging channel 5211 and the first oil-blocking and air-exchanging channel 411 are arranged in a staggered manner. The structure of the second oil-blocking and air-exchanging channel 5211 is similar to that of the first oil-blocking and air-exchanging channel 411.

[0031] In this embodiment, the handheld atomizer includes a housing 5. The oil storage bottle 1 is clamped to the lower part of the housing 5. The second seal includes a cylindrical convex part 521 provided on the upper part of the housing 5 and a sealing plug 6 plugged into the cylindrical convex part 521. The upper end of the oil delivery pipe 2 is fixedly sleeved on the outside of the cylindrical convex part 521. Specifically, the cylindrical convex part 521 serves to stably connect the oil delivery pipe 2 to the housing 5. The sealing plug 6 is arranged in the cavity of the cylindrical convex part 521, ensuring the compact structure of the handheld atomizer. In other embodiments of the present invention, the second sealing plug 6 can be plugged into the oil delivery pipe 2.

[0032] For the convenience of processing the second oil-blocking and air-exchanging channel 5211, in this embodiment, the second oil-blocking and air-exchanging channel 5211 is a groove provided on the inner side of the cylindrical convex part 521. Specifically, there are two second oil-blocking and air-exchanging channels 5211, and the two second oil-blocking and air-exchanging channels 5211 are symmetrically arranged on the inner cavity wall of the cavity of the cylindrical convex part 521.

[0033] In this embodiment, the housing 5 includes a top shell 52 and a cylindrical shell 51 connected to the lower end of the top shell 52. The cylindrical convex part 521 is provided at the lower end of the top shell 52. The atomization core 3 is arranged in the upper part of the cavity of the cylindrical shell 51, and the oil storage bottle 1 is arranged in the lower part of the cavity of the body. Specifically, the top shell 52 and the cylindrical shell 51 are detachably connected by a snap connection. In other embodiments of the present invention, the top shell 52 and the cylindrical shell 51 can be fixedly connected or connected by bolts.

[0034] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and substitutions can be made, and these improvements and substitutions should also be regarded as the protection scope of the present invention.
