They mainly generate aerosols by heating atomization substrates, which can be liquid substrates containing nicotine or not. Electronic atomizers generally include an atomization component and a power supply component, wherein the atomization component includes an oil tank and an atomization core for providing the atomization substrate. The oil tank is used to store the atomization substrate, and the atomization core is used to heat and atomize the atomization substrate to generate an aerosol. The power supply component supplies power to the atomization core.

[0049] See also Figure 1-Figure 15 As shown, the present application provides an electronic atomizer with a self-locking oil filling structure, the electronic atomizer 2 includes a shell 20 and a liquid storage bottle 1, an oil tank 21 is provided in the shell 20, a connecting portion 22 is provided on the shell 20 and is connected to the oil tank 21, the liquid storage bottle 1 and the connecting portion 22 are detachably connected, after the liquid storage bottle 1 is connected to the connecting portion 22, the liquid storage cavity 103 is connected to the oil tank 21; after the liquid storage bottle 1 is separated from the connecting portion 22, the valve body 14 closes the liquid storage cavity 103.

[0050] like Fig.15 As shown, the connecting portion 22 of the shell 20 of the electronic atomizer 2 is configured as a first toothed end surface 221 of a toothed tube extending outward, the teeth of the first toothed end surface 221 are roughly triangular, and the tooth surface is an inclined outer curved surface or a plane.

[0051] The liquid storage bottle 1 comprises: a bottle body 10, a valve body 14 and an elastic member, wherein a fluid channel 1410 capable of connecting the inner and outer spaces of the bottle body 10 is defined inside the valve body 14, one end of the elastic member is connected to the bottle body 10, and the other end of the elastic member is connected to the valve body 14, and the elastic member supports the valve body 14 through elastic force, so that the valve body 14 is located at a corresponding position to close the fluid channel 1410, thereby closing the liquid storage chamber 103. When the valve body 14 is subjected to an external force to compress the elastic member, the valve body 14 can rotate to a corresponding position relative to the bottle body 10, so that the valve body 14 can move toward the direction of the liquid storage chamber 103 until the fluid channel 1410 connects the inner and outer spaces of the bottle body 10.

[0052] like Figure 3As shown, the liquid storage bottle 1 includes a bottle body 10, the bottle body 10 defines a liquid storage cavity 103 for storing atomized matrix, and the bottle body 10 is provided with a mounting hole 100. The mounting hole 100 is a three-stepped hole, and the large hole 101, the middle hole, and the small hole 104 of the mounting hole 100 are arranged from the outside of the bottle body 10 to the inside of the bottle body 10 in sequence, wherein the large hole 101 is provided with a second toothed end face 132 extending downward in the inner circumference, and the inner wall of the middle hole is provided with an axially extending guide groove 102, the opening of the guide groove 102 is upward, and the guide groove 102 extends downward from the step between the large hole 101 and the middle hole. It can be understood that the large hole 101 is connected to the external space of the bottle body 10, the small hole 104 is connected to the liquid storage cavity 103, and the middle hole is connected to the large hole 101 and the small hole 104.

[0053] In some embodiments, the liquid storage bottle 1 further includes a positioning sleeve 13 fixed in the mounting hole 100, see Fig. 9 As shown, the positioning sleeve 13 is a cylindrical structure with two ends open, and a connection port 131 is provided at the upper end of the positioning sleeve 13. The lower end of the positioning sleeve 13 is close to the small hole 104, and its lower end extends toward the valve body 14 to form a second toothed end face 132 with a plurality of protruding triangular teeth. It can be understood that the connection port 131 can be connected to the bottle body to form the bottle mouth 11 of the liquid storage bottle 1. In addition, the second toothed end face 132 can be directly formed on the inner wall of the large hole 101, that is, a plurality of protruding triangular teeth are formed on the inner wall of the large hole 101, and the tips of the triangular teeth are downward, and the angle between the two inclined surfaces of the triangular teeth is an acute angle, and the inclined surface can be an outer curved surface or a flat surface.

[0054] Each tooth of the second toothed end surface 132 has a curvature, and a rough direction or angle is defined from the tooth top to the tooth root. When the valve body 14 abuts against the second toothed end surface 132, the valve body 14 can move along the contour of the second toothed end surface 132 under the support of the elastic member, that is, the valve body 14 rotates in the circumferential direction. It is worth noting that the positioning sleeve 13 can be directly formed integrally with the bottle body 10.

[0055] In some embodiments, when the liquid storage bottle 1 is combined with the external structure, the external structure can be inserted from the connecting port 131 and then connected to the valve body 14 .

[0056] The valve body 14 is provided with a fluid channel 1410 having a liquid outlet 1400 and a liquid inlet 1412. Figure 2-Figure 5 As shown, the liquid outlet 1400 of the valve body 14 is connected to the outside of the bottle body 10, and the liquid inlet 1412 is connected to the liquid storage cavity 103 inside the bottle body 10, and the axial direction of the liquid inlet 1412 is perpendicular to the axial direction of the mounting hole 100. Among them, the cross-section of the liquid inlet 1412 is any one of an ellipse, a circle, a rectangle or a triangle. It is understandable that the number of the liquid inlet 1412 is plural, and multiple liquid inlets 1412 can not only increase the liquid inlet area, but also prevent the surface tension of the atomized matrix from blocking the liquid inlet 1412.

[0057] like Figure 5-Figure 9 As shown, the valve body 14 is provided with a third toothed end face 1402, a locking protrusion 1404 and a guide block 1403 for use with an external structure, wherein the third toothed end face 1402 is constructed on the end face of the valve body 14 opposite to the first toothed end face 132, the tooth top of the third toothed end face 1402 faces the outside of the bottle body 10, the side surface of its teeth is an inclined surface, and the central axis of the third toothed end face 1402 is staggered with the central axis of the second toothed end face 132; the locking protrusion 1404 is circumferentially distributed on the outer wall of the valve body 14 and extends radially, and the locking protrusion 1404 can abut against the second toothed end face 132 when the valve body 14 moves upward; the guide block 1403 extends in the direction of the guide groove 102.

[0058] It is worth noting that the structure of the third toothed end surface 1402 can be the same as that of the second toothed end surface 132 , which is roughly triangular, and the side surface of the third toothed end surface 1402 can be an outwardly curved surface or a flat surface.

[0059] The valve body 14 includes an outer tube 140 and an inner tube 141 . The inner wall of the outer tube 140 and the outer wall of the inner tube 141 define a receiving cavity 16 . One end of the elastic member is connected to the valve body 14 in the receiving cavity 16 , and the other end of the elastic member is connected to the bottle body 10 .

[0060] like Figure 6 As shown, the upper and lower ends of the outer cylinder 140 are open, and a plurality of axially extending toothed end faces are provided on the side of the outer cylinder 140 close to the liquid outlet 1400. The outer cylinder 140 extends toward the side close to the liquid inlet 1412 to form a plurality of guide blocks 1403. Each guide block 1403 is constructed on the outer wall of the outer cylinder 140 along the axis between two adjacent toothed end faces, and the clamping protrusion 1404 is constructed on the outer wall of the outer cylinder 140. Figure 7 As shown, there are two latching protrusions 1404 , which are respectively constructed on the extension axis of the guide block 1403 , and the latching protrusions 1404 radially protrude from the outer wall of the outer cylinder 140 .

[0061] The upper part of the inner cylinder 141 is open, the bottom of the inner cylinder 141 is a closed end, and the axial length of the inner cylinder 141 is greater than that of the outer cylinder 140. When the outer cylinder 140 is sleeved on the inner cylinder 141, part of the inner cylinder 141 is exposed outside the outer cylinder 140, the liquid inlet 1412 is arranged on the side of the exposed part of the inner cylinder 141, and the fluid channel 1410 is constructed in the inner cylinder 141.

[0062] In some embodiments, the outer diameter of the outer cylinder 140 is larger than the inner diameter of the middle hole of the mounting hole 100 , so that the large hole 101 section of the mounting hole 100 constitutes the movable range of the valve body 14 .

[0063] In some embodiments, the inner cylinder 141 is connected to one side of the outer cylinder 140 near the liquid outlet 1400 to form a valve body 14, and the connection between the inner cylinder 141 and the outer cylinder 140 forms a closed end, and a receiving cavity 16 is formed between the outer wall of the inner cylinder 141 and the inner wall of the outer cylinder 140, and one end of the elastic member is inserted into the receiving cavity 16 and connected to the valve body 14.

[0064] In some embodiments, the outer cylinder 140 is sleeved on the inner cylinder 141, and one end of the outer cylinder 140 and the inner cylinder 141 are flush and connected to form one end closed and the other end open, and a receiving cavity 16 is formed between the outer wall of the inner cylinder 141 and the inner wall of the outer cylinder 140. The closed end of the inner cylinder 141 extends radially to form a skirt, which is exposed in the liquid storage cavity 103, and the skirt abuts against the inner wall 105 of the liquid storage cavity 103 under the elastic force of the elastic member to seal the liquid storage cavity 103.

[0065] In the above embodiment, one end of the elastic member is connected to the bottle body 10, and the other end of the elastic member is connected to the valve body 14. The elastic member provides a force to keep the valve body 14 away from the liquid storage chamber 103, so that the liquid inlet 1412 is hidden in the mounting hole 100, blocking the communication between the fluid channel 1410 and the liquid storage chamber 103. It is understandable that the elastic member can be an elastic block made of elastic material, or a spring 15. Figure 7 As shown, the elastic member is a spring 15 , and the spring 15 is sleeved on the inner cylinder 141 .

[0066] In some embodiments, the liquid storage bottle 1 further comprises a sealing member 12, which is fixed to the valve body 14 and exposed to the liquid storage chamber 103 together with the skirt. Fig.10 As shown, the sealing member 12 is a sealing ring, which is sleeved on the valve body 14 .

[0067] In some embodiments, the bottle body 10 at least partially protrudes outward and forms a bottleneck with a length, the mounting hole 100 passes through the bottleneck and is connected to the liquid storage cavity 103 and defines one end of the mounting hole 100 as the bottle mouth, and an annular groove is provided on the bottleneck, and a tensioning member is clamped in the annular groove, and the tensioning member is used to make the liquid storage bottle 1 and the shell 20 fit tightly.

[0068] Understandably, reference Fig.10 As shown, when the liquid storage bottle 1 is not in use, the valve body 14 is axially offset in the mounting hole 100 in the direction away from the liquid storage cavity 103 under the elastic force of the elastic member, and the locking protrusion 1404 can abut against the second toothed end surface 132, and the liquid inlet 1412 on the valve body 14 is hidden in the mounting hole 100 as the valve body 14 moves away from the liquid storage cavity 103. It can be understood that the locking protrusion 1404 slides along the contour of the second toothed end surface 132 and limits the deflection of the valve body 14, and the guide block 1403 can be staggered with the guide groove 102 when the valve body 14 deflects, and the guide block 1403 abuts against the step between the large hole 101 and the middle hole, and the valve body 14 cannot move to the side of the liquid storage cavity 103.

[0069] refer to Fig.11 As shown, the liquid storage bottle 1 is in use, the third toothed end face 1402 is driven by external force to compress the spring 15, the valve body 14 moves downward, the locking protrusion 1404 is separated from the second toothed end face 132, and the side of the third toothed end face 1402 is subjected to force, the valve body 14 is forced to turn when moving downward, and the guide block 1403 is rotated to a position opposite to the guide groove 102, the valve body 14 can continue to move downward and insert the guide block 1403 into the guide groove 102 until the liquid inlet 1412 is exposed in the liquid storage chamber 103, the guide block 1403 completes the moving stroke and abuts against the step between the middle hole of the mounting hole 100 and the small hole 104, at this time, the liquid inlet 1410 is exposed in the liquid storage chamber 103, and the liquid storage chamber 103 is connected with the external space through the fluid channel 1410.

[0070] like Figure 12-13 As shown, after the liquid storage bottle 1 is connected to the shell 20, the connecting portion 22 is inserted into the bottle mouth 11, and the first toothed end surface 221 presses against the third toothed end surface 1402, forcing the valve body 14 to compress the spring 15. At the same time, the third toothed end surface 1402 deflects the valve body 14 under the pressure of the first toothed end surface 221, and the valve body 14 turns, and the guide block 1403 rotates from a position staggered with the guide groove 102 to a position opposite to the guide groove 102, and the valve body 14 continues to move downward until the liquid inlet 1412 is exposed in the liquid storage chamber 103, and the atomized matrix stored in the liquid storage chamber 103 can be transferred to the oil tank 21 through the fluid channel 1410.

[0071] like Figure 14-15 As shown, after the liquid storage bottle 1 is separated from the shell 20, the connecting portion 22 is pulled out from the bottle mouth 11, and the liquid storage bottle 1 is restored to an unused state: the valve body 14 moves toward the bottle mouth 11 under the elastic force of the spring 15, and makes the liquid inlet 1412 hidden in the mounting hole 100, and the skirt on the valve body 14 abuts against the inner wall 105 of the liquid storage cavity 103, closing the liquid storage cavity 103, and at the same time, the latching protrusion 1404 abuts against the second toothed end surface 132, and the latching protrusion 1404 moves along the contour of the second toothed end surface 132 and deflects the valve body 14, and the guide block 1403 rotates to a position staggered with the guide groove 102. At this time, when the valve body 14 is subjected to a vertical external force, the guide block 1403 cannot be docked with the guide groove 102, and the valve body 14 cannot descend under the support of the spring 15, and the liquid storage cavity 103 remains in a closed state.

[0072] The above description is only a partial or preferred embodiment of the present invention. Neither the text nor the drawings can limit the scope of protection of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the overall concept of the present invention, or direct / indirect application in other related technical fields are included in the scope of protection of the present invention.
