Description

Technical Field

[0001] This invention relates to an electronic atomizer with an internally engaging connection between the mouthpiece and the main body assembly, specifically to a connection structure of the mouthpiece cap, the airway rod body, and the oil cup body of the electronic atomizer. Background Technology

[0002] The main structure of the upper part of an electronic atomizing device can be divided into the mouthpiece cap, the airway rod body, and the oil cup body. After the oil cup body of the electronic atomizing device is filled with atomized liquid, the mouthpiece cap, airway rod body, and oil cup body must be sealed together to prevent the atomized liquid from leaking out of the oil cup body. To prevent the mouthpiece cap from accidentally falling off under external force after being connected to the airway rod body, the connection methods of the mouthpiece cap and the body in electronic atomizing devices on the market are as follows: the mouthpiece cap is directly connected to the airway rod body, and the mouthpiece cap is connected to the oil cup body by a threaded connection or a multi-lobed hook structure. The direct connection between the mouthpiece cap and the airway rod body mainly has the following two connection methods: 1) A barb is machined around the upper end of the airway rod, and then the hook on the mouthpiece cap is hooked into the barb of the airway rod for connection. 2) An external thread is machined around the upper end of the airway rod, and then the internal thread on the mouthpiece cap is screwed into the external thread of the airway rod for connection.

[0003] In the connection structure of the nozzle cap, airway rod body, and oil cup body described above, the nozzle cap must not only have a threaded or multi-lobed hook structure for connecting to the oil cup body, but also a hook or threaded structure for connecting to the airway rod. In practical applications, the multi-lobed hook or threaded design on this type of nozzle cap is not only structurally complex but also costly. Summary of the Invention

[0026] The present invention provides an electronic atomizer with an internally engaging connection between the mouthpiece and the main body assembly, which has the following advantages.

[0027] 1) The mouthpiece and the center rod are connected by a connector. Since the connector has an elastic function, there is no need to add an extra elastic assembly component inside the mouthpiece, thereby reducing the number of electronic atomizer accessories and their assembly cost.

[0028] 2) The center rod and the connecting body can be pre-fitted together. In the subsequent assembly process of the connecting body and the mouthpiece, only two sealing silicone rubbers are needed to seal the gap between the mouthpiece and the oil cup and the gap between the mouthpiece and the center rod.

[0030] 4) The upper section of the connector is provided with several elastic hooks, and there are elastic gaps between the elastic hooks. When the moving hook at the upper end of the elastic hook comes into contact with the equal hook provided on the inner wall of the hollow cavity of the suction nozzle, the elastic hook can bend inward due to the setting of the elastic gap. The elasticity of the elastic hook bending inward and outward can effectively reduce and avoid damage to the moving hook and equal hook caused by hard contact.

[0031] 5) The electronic atomizer's central rod is made of metal, and the atomizer heating wire is located at the lower end of the central rod. The heat generated by the atomizer heating wire is conducted upwards through the central rod. Compared to the process of directly connecting the metal central rod to the mouthpiece, the metal rod body of the central rod in this invention is simpler to process, and the connector provides a heat insulation function between the central rod and the mouthpiece during use.

The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0051] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0052] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0053] like Figure 1 — Figure 4 As shown, the present invention discloses an electronic atomizer with an internally engaging mouthpiece and a main body assembly, comprising a mouthpiece 1 and a main body assembly.

[0055] Figure 1As shown in Figure 4, the connecting body 4 is a cavity structure that runs vertically through the body. Its upper section is connected to the suction nozzle 1, and its lower section is connected to the central rod 2. The upper section of the connecting body 4 is provided with several elastic hooks 4a, and the upper end of the elastic hooks 4a is provided with movable hooks 4b. Elastic gaps 4c are provided between the elastic hooks 4a.

[0057] The specific connection between the nozzle 1 and the connector 4 is as follows: Figure 1 As shown in Figure 1-2, the connecting body 4 is pre-fixed to the central rod 2. The suction nozzle 1 is pressed downward into the inner cavity of the oil cup 3. When the suction nozzle 1 moves downward, the movable hook 4b of the elastic hook frame 4a of the connecting body 4 bends inward under the pressure of the inner wall of the hook 1b of the suction nozzle 1, and the elastic gap 4c between the elastic hook frames 4a decreases. When the suction nozzle 1 moves downward and comes into complete contact with the oil cup 3, the movable hook 4b provided on the elastic hook frame 4a of the connecting body 4 is completely hooked on the upper end of the hook 1b of the suction nozzle 1, and the elastic hook frame 4a springs back outward to its initial state.
