Description

Technical Field

[0001] The invention relates to the field of oil injection mechanisms, and in particular to an electronic cigarette oil injection structure. Background Art

[0002] Electronic cigarette atomizers are widely used to replace ordinary cigarettes because they do not undergo combustion and do not contain toxic substances such as tar, carbon monoxide, and nitrite. At the same time, they also do not produce second-hand smoke that has a great impact on people around them. By controlling the nicotine content, they can also be used to get rid of the physical dependence on nicotine and achieve smoking cessation. Its working principle is to make the battery work through airflow sensing or pressing buttons, and the battery-powered heat is connected to the atomizer. The heat is used to evaporate the tobacco oil and atomize it to form smoke, achieving an effect similar to smoking.

[0003] When refilling the existing electronic cigarettes on the market, the oil filling port of the atomizer is generally filled with oil through a container with a thin tube. However, it is difficult to control the amount of oil filled by squeezing the container manually, which can easily cause excessive oil injection and overflow. At the same time, the thin tube is easy to fall off from the oil filling hole during oil filling, which can cause oil leakage and is difficult to clean.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The present invention provides Figure 1-8 An electronic cigarette oil filling structure shown in the figure includes a placement plate 1, a connection groove 2 is opened on the surface of the placement plate 1 in the structure, an oil pipe 3 is arranged at the bottom of the placement plate 1 in the structure, the oil pipe 3 is connected with the connection groove 2 in the structure, a limit rod 4 is arranged on the top of the placement plate 1 in the structure, the number of the limit rods 4 in the structure is set to multiple, and the multiple limit rods 4 are distributed around the center of the placement plate 1, the outer side of the limit rod 4 in the structure is provided with a thread, and an oil storage bottle 5 is arranged between the multiple limit rods 4, a connector 6 is arranged at the bottom of the oil storage bottle 5 in the structure, and a sealing film is arranged on the surface of the connector 6 in the structure, an extrusion mechanism is arranged on the top of the placement plate 1 in the structure, and a limit mechanism is arranged at the bottom of the oil pipe 3 in the structure.

[0028] Furthermore, in the above technical solution, the connecting head 6 in the structure matches the connecting groove 2, the oil storage bottle 5 in the structure is made of thermoplastic plastic material, and the outer side of the oil storage bottle 5 in the structure is configured to be corrugated. By configuring the oil storage bottle 5 to be corrugated, the oil storage bottle 5 can be more easily compressed.

[0029] Furthermore, in the above technical scheme, the extrusion mechanism in the structure includes a rotating ring 7 and an extrusion plate 8, the extrusion plate 8 in the structure matches the top of the oil storage bottle 5, a limiting protrusion 9 is provided on the outer side of the extrusion plate 8 in the structure, the number of limiting protrusions 9 in the structure is the same as the number of limiting rods 4, the limiting protrusions 9 in the structure are staggered, an annular groove 10 is provided on the inner side of the rotating ring 7 in the structure, the limiting protrusion 9 in the structure is rotatably connected with the annular groove 10, and the rotating ring in the structure is threadedly connected with the limiting rod 4. Because the rotating ring 7 is threadedly connected with the limiting rod 4, the extrusion plate 8 can be driven to move downward on the surface of the limiting rod 4 by rotating the limiting rod 4, and at the same time, the bottom of the extrusion plate 8 will squeeze and compress the oil storage bottle 5, so that the smoke oil in the oil storage bottle 5 can be squeezed out conveniently and stably, and at the same time, the reverse rotation of the rotating ring 7 can make the rotating ring 7 drive the extrusion plate 8 to separate from the limiting rod 4, so that the oil storage bottle 5 that needs to be replaced can be placed between multiple limiting rods 4.

[0030] Further, in the above technical solution, the limiting mechanism in the structure includes a rotating sleeve 11, a first slide groove 12 and a ring 13, the ring 13 in the structure is arranged at the bottom of the oil pipeline 3, the top of the ring 13 in the structure is fixedly connected to the oil pipeline 3, the rotating sleeve 11 in the structure is sleeved and arranged on the outside of the oil pipeline 3, the rotating sleeve 11 in the structure is rotatably connected to the oil pipeline 3, the first slide groove 12 in the structure is arranged on the outside of the oil pipeline 3, the number of the first slide grooves 12 in the structure is set to multiple, the first push rods 14 are slidably arranged inside the multiple first slide grooves 12, the first push rods 14 in the structure, and the outer sides of the multiple first push rods 14 are connected to the rotating sleeve 11. The inner side of the sleeve 11 is threadedly connected, and an elastic sheet 15 is fixedly connected between the first push rod 14 and the push ring 13 in the structure. First, the bottom of the oil pipe 3 is inserted into the oil filling hole. Because the outer side of the first push rod 14 is threadedly connected to the inner side of the rotating sleeve 11, the rotating sleeve 11 can drive multiple first push rods 14 to slide along the first slide groove 12. At the same time, one end of the first push rod 14 will squeeze the elastic sheet 15, so that the elastic sheet 15 will be deformed, so that the oil filling hole can be stuck by multiple deformed elastic sheets 15, thereby preventing the oil pipe 3 from being separated from the oil filling hole during the oil filling process, thereby preventing the smoke oil from accidentally spilling.

[0031] Further, in the above technical solution, a sliding plate 16 is slidably arranged inside the connecting groove 2 in the structure, a connecting pipe 17 is penetrated in the middle of the sliding plate 16 in the structure, the bottom of the connecting pipe 17 in the structure is plugged and arranged inside the oil pipeline 3, the top of the connecting pipe 17 in the structure is set to be conical, the connecting pipe 17 in the structure matches the connector 6, a connecting hole 18 is opened on the outside of the top of the connecting pipe 17 in the structure, the number of the connecting holes 18 in the structure is set to be multiple, a second slide groove 19 is opened on the outside of the oil pipeline 3 in the structure, the number of the second slide grooves 19 in the structure is set to be multiple, and the multiple second slide grooves 19 are distributed around the center of the oil pipeline 3, and the multiple second slide grooves 19 are distributed around the center of the oil pipeline 3.

Because the outer sides of the second push rods 20 are threadedly connected to the rotating sleeve 11, the second push rods 20 can be driven to slide in the second sliding groove 19 by rotating the rotating sleeve 11, so that the sliding plate 16 and the connecting pipe 17 are driven to move upward by the second push rod 20, so that the connecting pipe 17 pierces the sealing film on the surface of the connecting head 6. At this time, the tobacco oil in the oil storage bottle 5 can be transported to the part requiring oil injection through the connecting hole 18 and the oil delivery pipe 3 through the extrusion mechanism.

[0032] Furthermore, in the above technical solution, a fixing ring 21 is fixedly connected to the outer side of the oil pipeline 3 in the structure, the number of the fixing rings 21 in the structure is set to multiple, and the multiple fixing rings 21 are evenly distributed. The first push rod 14 and the second push rod 20 in the structure are matched with the fixing ring 21. By setting the fixing ring 21, the first push rod 14 and the second push rod 20 can be limited, thereby avoiding the first push rod 14 and the second push rod 20 from being subjected to force and bending.

[0033] Furthermore, in the above technical scheme, a fixing mechanism is provided between the rotating ring 7 and the placement plate 1 in the structure, and the fixing mechanism in the structure includes a fixing rod 22 and a fixing sleeve 23. The fixing rod 22 in the structure is arranged on the outside of the rotating ring 7, and one end of the fixing rod 22 in the structure is hinged to the rotating ring 7, and the specified sleeve in the structure is arranged on the outside of the placement plate 1, and the fixing sleeve 23 in the structure is fixedly connected to the placement plate 1, and a clamping protrusion 24 is provided at the end of the fixing rod 22 away from the rotating ring 7 in the structure, and a clamping groove 25 is provided on the inner side of the fixing sleeve 23 in the structure. The number of fixing rods 22 in the structure is the same as that of the fixing sleeve 23, and the clamping protrusion 24 in the structure matches the clamping groove 25. The fixing rod 22 and the fixing sleeve 23 can be fixed by the clamping protrusion 24 and the clamping groove 25. At this time, the rotating ring 7 can be prevented from rotating accidentally, and the rotating ring 7 can be easily rotated by rotating and unfolding multiple fixing rods 22.

[0034] Furthermore, in the above technical solution, an anti-skid groove 26 is provided on the outside of the rotating sleeve 11, and the number of the anti-skid grooves 26 in the structure is set to be multiple, and the multiple anti-skid grooves 26 are distributed around the center of the rotating sleeve 11. A sealing ring 27 is provided on the top of the sliding plate 16 in the structure, and the sealing ring 27 in the structure is sleeved on the outside of the connecting pipe 17. By providing the anti-skid groove 26, the friction force on the outside of the rotating sleeve 11 can be increased, thereby facilitating the rotation of the rotating sleeve 11, and by providing the sealing ring 27, the air tightness between the connecting pipe 17 and the connecting head 6 can be improved.

[0035] How this utility works:

[0036] Refer to the instruction manual Figure 1-8 When the device is in use, because the rotating ring 7 is threadedly connected to the limiting rod 4, the limiting rod 4 can be rotated to drive the squeezing plate 8 to move downward on the surface of the limiting rod 4, and at the same time, the bottom of the squeezing plate 8 will squeeze and compress the oil storage bottle 5, so that the smoke oil in the oil storage bottle 5 can be squeezed out conveniently and stably. At the same time, the rotating ring 7 can be rotated in the opposite direction to drive the squeezing plate 8 to separate from the limiting rod 4, so that the oil storage bottle 5 that needs to be replaced can be placed between multiple limiting rods 4;

[0037] Refer to the instruction manual Figure 1-8 When the device is in use, the bottom of the oil delivery pipe 3 is first inserted into the oil filling hole. Because the outer side of the first push rod 14 is threadedly connected to the inner side of the rotating sleeve 11, the rotating sleeve 11 can drive multiple first push rods 14 to slide along the first slide groove 12. At the same time, one end of the first push rod 14 will squeeze the elastic sheet 15, so that the elastic sheet 15 will deform, so that the multiple deformed elastic sheets 15 can clamp the oil filling hole, thereby preventing the oil delivery pipe 3 from being separated from the oil filling hole during the oil filling process, thereby preventing the smoke oil from accidentally spilling.
