[0045] Embodiments of the atomization tube in the application:

[0046] In one embodiment, an atomization tube is provided. The atomization tube 100 can be understood as a structural component in the atomizer for accommodating the atomization core 200 and providing an airway for the atomizer. Please refer to Figure 1 and Figure 2The atomizing tube 100 has a hollow inner cavity 110, which includes an atomizing section 111 for mounting the atomizing core 200. The cavity wall of the atomizing section 111 is provided with a liquid inlet through hole 120 and a liquid storage groove 130. The liquid storage groove 130 is in fluid communication with the liquid inlet through hole 120, and is used to store the atomizing liquid input by the liquid inlet through hole 120 and supply the atomizing core 200.

[0047] The liquid storage groove 130 can store a small amount of atomizing liquid for standby, so that the atomizing liquid in the liquid storage cavity 400 of the atomizer can still be supplied to the atomizing core 200 after the atomizing liquid is consumed, to provide some puffing number, help the user to find that the atomizing liquid in the liquid storage cavity 400 is consumed based on the change of the puffing feeling caused by the puffing resistance in the continuous puffing process, and stop puffing, reduce the risk of the paste core, protect the user's use experience, and reduce the possibility of damage to the atomizing core 200.

[0048] Exemplarily, referring to Figure 1 The atomizing tube 100 can be a straight tube with both ends open, and the hollow inner cavity 110 has an atomizing section 111 and an air outlet section 112 arranged along the axial direction. The atomizing section 111 is used to mount the atomizing core 200. The liquid inlet through hole 120 and the liquid storage groove 130 are arranged on the cavity wall of the atomizing section 111, and the liquid storage groove 130 and the liquid inlet through hole 120 are in communication. The atomizing liquid outside the atomizing tube 100 can flow into the liquid storage groove 130 through the liquid inlet through hole 120, and then be supplied to the atomizing core 200, heated and atomized by the atomizing core 200 to generate aerosol, and then be sucked out by the air outlet section 112. Those skilled in the art can understand that the shape of the atomizing tube 100 and the arrangement position of the atomizing section 111 are not limited, and any shape that can meet the design and use requirements can be used.

[0049] In an embodiment, referring to Figure 1 The liquid storage groove 130 can be an annular groove arranged circumferentially around the atomizing section 111, so as to supply the atomizing liquid to the atomizing core 200 from the circumferential side, which helps to avoid local overheating of the atomizing core 200 due to lack of atomizing liquid during use. In other embodiments, the liquid storage groove 130 can also be arranged in multiple around the circumference of the atomizing section 111, so as to supply the atomizing liquid to the atomizing core 200 from the circumferential side.

[0050] In an embodiment, referring to Figure 1 The cavity wall of the atomizing section 111 is provided with two protruding portions 140 spaced apart along the axial direction of the atomizing section 111, for fixing the atomizing core 200. The protruding portions 140 are arranged circumferentially around the atomizing section 111, and the liquid storage groove 130 is formed between the two protruding portions 140.

[0051] By setting two protrusions 140, the liquid storage groove 130 can be formed while the atomizing core 200 is fixed, which facilitates the setting of the liquid storage groove 130 in the case of a thin wall of the atomizing tube 100, and helps to adapt to the application of a small-sized atomizer.

[0052] Exemplarily, refer to Figure 1 The space surrounded by the protrusions 140 and the outer contour of the atomizing core 200 are adapted, so that when the atomizing core 200 is installed in the atomizing section 111, the two ends of the atomizing core 200 in the axial direction can be clamped in the space surrounded by one protrusion 140, and the part of the atomizing core 200 between the two protrusions 140 is surrounded in the liquid storage groove 130 to absorb the atomizing liquid in the liquid storage groove 130.

[0053] In other embodiments, the liquid storage groove 130 can also be formed by thinning the local wall of the atomizing tube 100.

[0054] In an embodiment, refer to Figure 1 The liquid inlet through hole 120 can be arranged between the two protrusions 140, and the diameter of the liquid inlet through hole 120 is smaller than the width of the liquid storage groove 130, and the liquid inlet through hole 120 is arranged apart from at least one protrusion 140. Those skilled in the art can understand that the protrusion 140 arranged apart from the liquid inlet through hole 120 should be located on the side away from the gas outlet end of the atomizing tube 100, i.e. below the perspective view of the liquid inlet through hole 120, so that when the atomizing liquid in the liquid storage cavity 400 is exhausted, the protrusion 140 and the liquid inlet through hole 120 can still store atomizing liquid.

[0055] Exemplarily, refer to Figure 1 The liquid inlet through hole 120 is a circular hole with a diameter smaller than the width of the liquid storage groove 130, the liquid inlet through hole 120 is arranged between the two protrusions 140, and is located at the middle of the liquid storage groove 130 in the width direction, and the liquid inlet through hole 120 is arranged apart from the two protrusions 140. In other embodiments, the liquid inlet through hole 120 can also be arranged as a long hole or other shapes, and the size of the liquid inlet through hole 120 in the width direction of the liquid storage groove 130 is smaller than the width of the liquid storage groove 130, so that the liquid inlet through hole 120 can be arranged apart from at least one protrusion 140.

[0056] In an embodiment, refer to Figure 1The side of the at least one protrusion 140 away from the liquid storage groove 130 is provided with a slope surface 141 to smoothly transition the protrusion 140 and the cavity wall of the hollow inner cavity 110. Exemplarily, the side of the two protrusions 140 away from the liquid storage groove 130 is provided with a slope surface 141, which can be entirely located in the atomization section 111 or extend out of the atomization section 111. By providing the slope surface 141, the atomization core 200 can be guided during installation, which facilitates installation and also helps to reduce the dead angle of air guidance in the hollow inner cavity 110, which not only facilitates air circulation but also helps to avoid condensate accumulation.

[0057] Embodiments of the atomizer in the present application:

[0058] In an embodiment, an atomizer is provided, referring to Figure 1 and Figure 2 , comprising a shell 300, an atomization tube 100 and an atomization core 200, the atomization tube 100 is any one of the above-mentioned embodiments of the atomization tube 100, the atomization tube 100 is arranged in the shell 300, and the atomization core 200 is arranged in the atomization section 111. A liquid storage cavity 400 is arranged around the atomization tube 100 in the shell 300 to store atomization liquid, and the liquid storage cavity 400 is in communication with the liquid storage groove 130 through the liquid inlet through hole 120 to supply atomization liquid to the atomization core 200.

[0059] The atomization core 200 can be understood as a functional component for absorbing and heating atomization liquid to atomize the atomization liquid to generate aerosol, which is one of the core components in the atomizer. In an embodiment, referring to Figure 1 and Figure 2 , the atomization core 200 comprises a liquid storage member 210, which is attached to the cavity wall of the atomization section 111 to absorb the atomization liquid in the liquid storage groove 130.

The liquid storage member 210 can be arranged as liquid storage cotton or microporous ceramic, etc. to absorb the atomization liquid in the liquid storage groove 130.

[0061] Those skilled in the art can understand that in other embodiments, the liquid storage groove 130 can also be cancelled on the atomizing tube 100, and a liquid storage space similar to the liquid storage groove 130 can be formed by the outer surface of the liquid storage member 210. For example, the liquid storage member 210 can be in the shape of a sandglass with large ends and a small middle part. When installed, the middle part of the liquid storage member 210 is opposite to the liquid inlet through hole 120, so that the liquid storage member 210 and the wall of the atomizing tube 100 can form a liquid storage space around the liquid storage member 210. The liquid storage space can be used to store atomizing liquid for standby, so as to provide a certain number of suction holes after the atomizing liquid in the liquid storage cavity 400 is consumed. Of course, the liquid storage member 210 can also be in other shapes or structures, as long as it can form a liquid storage space for storing atomizing liquid.

For example, a flow-guiding groove can be provided on the surface of the sealing seat 322 on the side that connects with the liquid storage chamber 400, so that the groove wall serves as the flow-guiding slope 3222.

[0065] In one embodiment, please refer to Figure 2 The atomizer also includes a seal 500, which can be a sealing ring or a sealing sleeve, etc., to seal the interface gap between the atomizing tube 100 and the aerosol outlet 311.
