Description

Technical Field

[0001] The utility model relates to the field of electronic atomization, and particularly to an electronic atomizer main body and an electronic atomizer. Background Art

[0002] An electronic atomizer, also known as an electronic cigarette, electronic aerosol or electronic nicotine delivery system, is an electronic device that simulates the smoking experience by heating a liquid to produce vapor. An electronic atomizer generally consists of a cartridge and a main body. Driven by the main body, the cartridge heats the e-liquid to produce smoke for users to inhale.

[0003] With the continuous development of electronic atomizers, more and more functions have emerged on electronic atomizers. Buttons and displays have almost become standard configurations. Therefore, the volume of the circuit board has gradually increased to accommodate more electronic components. However, the internal volume of the electronic atomizer is limited, and the volume of the electronic atomizer is getting smaller and smaller. So, how to effectively utilize the internal space in a small-sized electronic atomizer while continuously simplifying the structure of the electronic atomizer, especially the assembly structure, reducing components, and lowering the assembly time and cost, is a problem that needs to be solved currently. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the above-mentioned defects in the prior art, and provide an electronic atomizer main body, which optimizes the structure of the housing, is beneficial to simplifying the assembly process, utilizes the idle space to construct the assembly space of the PCB control main board, and improves the utilization rate of the internal space.

[0005] To achieve the above purpose, the utility model provides an electronic atomizer main body and an electronic atomizer, including:

[0006] An upper housing, in which a first cavity and a second cavity are formed at intervals;

[0007] A lower housing hermetically snap-connected to the upper housing. The lower housing is provided with an integrally formed housing support. The upper end of the housing support is a connecting portion, and the connecting portion is hermetically inserted into the first cavity. The connecting portion and the inner wall of the first cavity form a first installation cavity for accommodating a cartridge. At least one first air inlet is provided at the lower end of the housing support. A receiving groove communicating with the first installation cavity is provided on the connecting portion, and a second air inlet communicating with the first air inlet is opened on the receiving groove. A second installation cavity for accommodating a battery is formed at the other end of the housing support away from the connecting portion;

[0008] A battery installed in the second installation cavity;

[0009] A PCB control main board connected to the battery, one end of the PCB control main board is embedded in the second cavity, and the other end of the PCB control main board is detachably connected to the housing support.

[0010] Furthermore, the side wings of the housing support extend to form a mounting portion, and a first mounting hole for connecting to the PCB control main board is provided on the mounting portion. It can cooperate with the installation of the PCB control main board to achieve a split installation with the housing support. Combining with the second cavity, a large-sized PCB control main board can be installed using the space of the second cavity, increasing the functions of the electronic atomizer.

[0011] Furthermore, a first seal, a microphone, a microphone mounting hole, and a microphone connection groove are provided on the mounting portion. The microphone is connected to the PCB control main board and installed on the microphone mounting hole. The microphone mounting hole communicates with the microphone connection groove. A third through hole communicating with the microphone connection groove is provided on the receiving groove, and the first seal is snap-fitted into the microphone connection groove to seal the microphone connection groove. In this way, the microphone is connected to the first air inlet hole, and the microphone can be triggered to start in real time during use.

[0012] Furthermore, a communication groove for communicating the third through hole and the microphone mounting hole is provided on the first seal. It ensures the smoothness between the third through hole and the microphone mounting hole, and the cleaning of the microphone connection groove can be achieved by disassembling the first seal.

[0013] Furthermore, a first supporting portion is formed between the housing support and the connecting portion. The wall of the first cavity abuts against the first supporting portion. A first groove is provided on the connecting portion, and a first sealing ring is provided on the first groove. The first sealing ring is in close contact with the inner wall of the first cavity. By the abutment of the first supporting portion against the wall of the first cavity, combined with the first seal, a good sealing performance can be achieved between the first cavity and the connecting portion.

[0014] Furthermore, a fifth through hole penetrating the connecting portion and the housing support is provided on the connecting portion, and an electrode connected to the PCB control main board is installed on the fifth through hole. When the cartridge is installed, it can be electrically connected to the PCB control main board through the electrode.

[0015] Furthermore, a magnet is included. The magnet is a hollow ring structure, and the magnet passes through the electrode and is installed in the fifth through hole. The magnet and the electrode are installed in the fifth through hole, further optimizing the structure and improving the space utilization rate.

[0016] Further, a control button is provided on the PCB control main board. The upper shell is provided with a sixth through hole that matches the position of the control button. A button is buckled on the sixth through hole, and a silicone connection key is provided between the button and the control button. The silicone connection key provided between the button and the control button ensures that the button will not get stuck during pressing, improves the feel of the button, and enhances the user experience.

[0017] Further, on the other end of the PCB control main board away from the second cavity, an LED lamp bead is provided, and a light-shielding member is disposed around the LED lamp bead. This solves the problem of uneven light diffusion when the PCB control main board lights up and has a good light-shielding effect, thus solving the problem of light leakage.

[0018] An electronic atomizer includes the above-mentioned electronic atomizer main body.
