Description

Technical Field

[0001] The utility model relates to the technical field of atomizers, in particular to an electronic atomizer which prevents cigarette oil from leaking. Background Art

[0002] Electronic atomizers, also often referred to as e-cigarettes, are devices that use batteries to drive the atomizer core to heat the smoke liquid into steam, which is used to simulate the smoking experience. The working principle of electronic atomizers is based on the process of electrically heating liquid to atomize. It usually consists of three parts: batteries, atomizers, and cartridges. The battery provides power to the atomizer, and the heating element inside the atomizer heats the liquid in the cartridge to the evaporation point, forming a smoke-like aerosol. Users simulate the smoking process by inhaling these aerosols.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-3 , an electronic atomizer for preventing smoke oil from leaking, comprising an atomizer housing 1 and an oil filling hole arranged at the upper end thereof, a sealing cover 6 is provided at the upper end of the atomizer housing 1, for sealing the oil filling hole, a rubber pad 11 is fixedly connected to the lower end of the sealing cover 6, for improving the sealing performance of the sealing cover 6, the sealing cover 6 is located just above the oil filling hole, a rubber plug 10 is fixedly connected to the lower end of the sealing cover 6, for sealing the oil filling hole, the lower end of the rubber plug 10 slides and extends into the oil filling hole, a lead screw 8 is inserted at the upper end of the atomizer housing 1 and near the edge, for driving the sealing cover 6 to rise and fall, the lead screw 8 and the atomizer housing 1 are threadedly connected, the upper end of the lead screw 8 passes through the sealing cover 6 and is fixedly connected to a knob 7, for facilitating the user to rotate the lead screw 8, the lead screw 8 and the sealing cover 6 are rotatably connected, a rubber strip is fixedly connected to the outer wall of the knob 7, for playing an anti-slip role when the knob 7 is rotated;

[0023] In this embodiment, a liquid infusion tube 2 communicating with the oil filling hole is fixedly connected to the inner top of the atomizer housing 1 for circulating the smoke oil. A plurality of mounting blocks 12 are fixedly connected to the inner side wall of the liquid infusion tube 2 near the bottom for mounting a spring 13. The lower end of the mounting block 12 is fixedly connected to a spring 13 for pulling the sealing disk 15 to rise and reset. A sealing disk 15 is provided at the lower end of the liquid infusion tube 2 for sealing the liquid infusion tube 2. The lower end of the spring 13 penetrates the liquid infusion tube 2 and is fixedly connected to the upper end of the sealing disk 15. The upper end of the sealing disk 15 is fixedly connected to a rubber ring 14 for improving the sealing effect.

[0024] In this embodiment, a push rod 3 is fixedly connected to the upper end of the sealing disk 15 and near the center position, which is used to push the sealing disk 15 down. The upper end of the push rod 3 passes through the infusion tube 2 and is fixedly connected to a cross-shaped connecting rod 9, which is used to drive the push rod 3 to descend. The connecting rod 9 is located in the oil filling hole. The lower end of the push rod 3 is fixedly sleeved with a fixing ring 16, which is used to improve the firmness between the push rod 3 and the sealing disk 15. The lower end of the fixing ring 16 is fixedly connected to the upper end of the sealing disk 15. A guide cylinder 4 is slidingly sleeved on the push rod 3 to keep the push rod 3 moving in a straight line and prevent it from tilting. A plurality of fixing rods 5 are fixedly connected to the outer wall of the guide cylinder 4 for fixing the guide cylinder 4. The fixing rod 5 is fixedly connected to the inner wall of the infusion tube 2 at one end away from the guide cylinder 4.

[0025] In this embodiment, the knob 7 is first manually turned to drive the lead screw 8 to rotate. The lead screw 8 is lifted and lowered in the atomizer housing 1 through the action of threaded engagement (the lifting and lowering is controlled by the user turning the knob 7 forward and reverse). The lead screw 8 drives the sealing cover 6 to lift and lower. When the sealing cover 6 descends, it will seal the oil filling hole and drive the rubber plug 10 to be inserted into the oil filling hole to improve the sealing effect. When the sealing cover 6 rises, the sealing cover 6 is manually rotated to one side to avoid blocking the oil filling hole. Then, the bottle mouth of the liquid storage bottle filled with tobacco oil is inserted into the oil filling hole. After the bottle mouth is inserted into the oil filling hole, it will push the connecting rod 9 to descend, and the connecting rod 9 is connected. The rod 9 pushes the sealing plate 15 downward and away from the infusion tube 2 through the push rod 3. At this time, the tobacco oil in the liquid storage bottle enters the oil filling hole through the bottle mouth, and the tobacco oil in the oil filling hole flows into the infusion tube 2 and then flows into the atomizer housing 1. After the oil filling is completed, the liquid storage bottle is removed. At this time, the sealing plate 15 is pulled up and reset by the elasticity of the spring 13, so that the upper end of the sealing plate 15 is against the lower end of the liquid storage tank 2, thereby playing a sealing role. At the same time, the rubber ring 14 is used to further improve the sealing effect; when filling oil, a syringe or a needle tube or other tools can also be used to store tobacco oil, and then the syringe or needle tube can be inserted into the oil filling hole.

[0026] As mentioned above, the atomizer housing is an existing mature technology, and its working principle and internal structure are known to technicians in the relevant technical field. This application only utilizes its function and does not improve its internal structure. Therefore, it will not be described in detail.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
