Description

Technical Field

[0001] This utility model relates to the field of atomizer technology, specifically to an atomizer with a stable internal structure. Background Technology

[0002] Existing refillable atomizers generally consist of a power supply unit and an atomizing unit. The atomizing unit comprises an atomizer reservoir, a heating element, and a mouthpiece, primarily used for storing and atomizing the atomizer. The power supply unit provides power to the atomizer. Currently, most refillable atomizers on the market allow for direct replacement of the atomizing unit, which is very simple and convenient. This solves the problems of ordinary atomizers, such as the need for repeated refilling of atomizer and the inconvenience of carrying them, making them popular among users.

[0003] However, existing refillable atomizers often have relatively scattered internal electronic components, which are easily damaged by collisions or drops. Furthermore, the scattered internal electronic components require multiple wires to connect to each other, resulting in messy wiring. This is especially true when there are light or screen components, which further increase the number of internal wires. The messy wiring structure occupies the limited internal space, forcing manufacturers to compress the layout optimization space of core components such as heating elements and batteries, directly affecting atomization efficiency and battery life.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0026] This embodiment relates to an atomizer with a stable internal structure, such as... Figure 1 As shown, this atomizer includes an atomizing body 2 and a power supply body 1. The atomizing body 2 is provided with an outer shell 21, and a heating element is provided inside the outer shell 21. The atomizing body 2 is also provided with an atomizing liquid that can be heated by the heating element to generate an aerosol. A mouthpiece 22 is provided at the top of the atomizing body 2, and a fifth air inlet 26 is provided at the bottom of the atomizing body 2. An atomizing channel is formed between the fifth air inlet 26 and the mouthpiece 22, and the heating element is located in the atomizing channel, thereby heating the atomizing liquid in the atomizing channel to generate an aerosol for the user to inhale.

[0027] like Figure 2 and Figure 3As shown, the bottom of the atomizing body 2 is provided with a power receiving part, which is a contact 24. There are two contacts 24, namely a positive contact 24 and a negative contact 24. An insertion cavity 12 is provided on the power supply body 1, with the opening of the insertion cavity 12 facing upward. The insertion cavity 12 allows the atomizing body 2 to be detachably inserted. A receiving seat 17 is provided at the bottom of the insertion cavity 12, and a power supply part is provided on the receiving seat 17. The power supply part is a spring pin 173 corresponding to the contact 24. There are also two spring pins 173, one for the positive contact 24 and one for the negative contact 24. When the atomizing liquid in the atomizing body 2 is used up, or when it is necessary to replace the atomizing body 2 containing a different composition of atomizing liquid, simply pull out the atomizing body 2 from the insertion cavity 12 and replace it with another atomizing body 2.

[0028] In other embodiments, the power receiving part at the bottom of the atomizing body 2 is a plug, and the power supply part on the receiving seat 17 is a socket. The coupling between the atomizing body 2 and the power supply body 1 can be achieved by inserting the plug into the socket.

[0029] It should be added that a first magnetic attraction part 25 is also provided at the bottom of the atomizing body 2, and a second magnetic attraction part 174 is provided on the receiving seat 17 to magnetically engage with the first magnetic attraction part 25, thereby achieving a stable assembly of the atomizing body 2 within the insertion cavity 12. In other embodiments, the first magnetic attraction part 25 is provided on the side of the atomizing body 2, and the second magnetic attraction part 174 is also provided on the side of the insertion cavity 12. After the two are magnetically assembled, a stable assembly of the atomizing body 2 within the insertion cavity 12 can also be achieved. Specifically, both the first magnetic attraction part 25 and the second magnetic attraction part 174 are magnets, and multiple magnets can be provided to improve the stability of the magnetic assembly.

[0030] Preferably, a sealing plug 23 may also be provided on the mouthpiece 22. The sealing plug 23 can be inserted into the mouthpiece 22 when not in use to prevent dust or dirt from falling from the mouthpiece 22 into the airflow channel. A hook slot 11 is also provided on the power supply unit 1. The hook slot 11 can be used for hanging ropes or keychains to pass through, so as to facilitate the user to carry this atomizer.

[0031] The power supply unit 1 has a cavity for placing electronic components. The cavity opening faces downwards, and a base 13 is fixedly mounted at the cavity opening. The cavity facilitates the installation of electronic components into the power supply unit 1 by the assembly personnel. After all the electronic components are assembled into the cavity, the base 13 is closed, thus completing the assembly of the power supply unit 1. Specifically, the base 13 has multiple buckles on its edge, and corresponding slots are provided in the cavity opening. After the buckles and slots are engaged, the base 13 is fixedly mounted at the cavity opening.

[0032] Preferably, such as Figure 4 and Figure 5The electronic components within the cavity include: a control circuit board 15, a PCB board 16, a power supply unit, and a display module. The power supply unit is a spring-loaded pin 173. The control circuit board 15 is coupled to the bottom of the spring-loaded pin 173, and a receiving seat 17 passes through the top of the spring to facilitate coupling with the contact point 24 at the bottom of the atomizing body 2. The PCB board 16 is fixedly mounted and coupled to one side of the control circuit board 15. The display module is mounted on the PCB board 16 and can display at least power information. Specifically, the connection between the PCB board 16 and the control circuit board 15 is soldered, or a board-to-board connector is used to assemble them. This allows for coupling of the electronic components within the cavity without the need for wires. The assembled control circuit board 15 and PCB board 16 are arranged at an angle, specifically forming an L-shaped plate structure. The control circuit board 15 is mounted at the bottom of the cavity, and the PCB board 16 is mounted to the side wall of the cavity using fasteners, improving the stability of the L-shaped plate structure after assembly within the cavity.

[0033] Preferably, the receiving seat 17 is fixedly mounted on the upper part of the control circuit board 15, and the control circuit board 15 is fixedly mounted on the base 13. The electronic component is a power supply unit, which is a battery 18. The battery 18 is preferably a rechargeable lithium battery 18. The battery 18 is electrically connected to the control circuit board 15 or the PCB board 16, and the battery 18 is fixedly mounted on an L-shaped plate. Specifically, foam double-sided tape is provided between the side of the battery 18 and the back of the PCB board 16 to fix the side of the battery 18 and provide shock absorption for the battery 18; the bottom of the battery 18 is soldered to the control circuit board 15, thereby fixing the bottom of the battery 18 and coupling the battery 18 to the control circuit board 15.

[0034] It should be added that a power supply socket 152 is mounted on the control circuit board 15, and an exposed opening 132 is provided on the base 13 at the position corresponding to the power supply socket 152. The power supply socket 152 passes through the exposed opening 132 on the base 13, and the power supply socket 152 can provide an external power source to charge the battery 18.

[0035] In this embodiment, the display module consists of multiple LEDs 161 arranged in a straight line. Specifically, the multiple LEDs 161 are arranged in a straight line along the length of the PCB board 16, and the spacing between each pair of adjacent LEDs 161 is the same. There are four LEDs 161, and the number of LEDs on and off indicates the battery level of the battery 18. Specifically, when all four LEDs are lit, the battery level is in the 80%-100% full charge range; if three LEDs are lit, the battery level is 50%-80% remaining; if only two LEDs are lit, the battery level has dropped to 20%-50%; if only one LED is flashing, the battery level is below 20% and needs to be charged promptly.

[0036] It should be noted that the portion of the sidewall of the receiving cavity near the LED light 161 is made of a light-transmitting material. In other embodiments, the light from the LED light is directly emitted through a light-transmitting hole in the sidewall of the receiving cavity. This enables the atomizer to display its battery level, allowing the user to easily know the battery level of the atomizer in real time.

[0037] Preferably, a transition block 14 is provided between the control circuit board 15 and the base 13. The top of the transition block 14 is attached to the control circuit board 15, and the bottom of the transition block 14 is attached to the base 13. The transition block 14 is used to reduce the gap between the control circuit board 15 and the base 13, enhance the stability of the circuit board, and reduce the risk of solder joint fatigue of electronic components caused by vibration. The transition block 14 is preferably made of flexible materials such as silicone or rubber to improve the shock absorption capacity of the control circuit board 15. In other embodiments, the silicone is made of plastic.

[0038] It should be added that screw holes 151 are provided on the control circuit board 15, and through holes 143 corresponding to the screw holes 151 are provided on the transition block 14. An internally threaded post 134 passing through the through hole 143 is provided on the base 13. The screw holes 151 allow screws to pass through and be threaded onto the internally threaded post 134. Thus, the control circuit board 15 and the transition block 14 are both fixedly mounted on the base 13 by screws. When the control circuit board 15 is fixedly mounted, the receiving seat 17 on the control circuit board 15 is also fixedly mounted. Four sets of screws, screw holes 151, through holes 143, and internally threaded posts 134 are provided to improve the stability of the power supply body 1 after assembly.

[0039] Preferably, a first air inlet 131 is provided on the base 13, a first air passage 141 and a second air inlet 142 communicating with the first air inlet 131 are provided on the transition block 14, a second air passage 153 communicating with the first air passage 141 is provided on the control circuit board 15, a third air inlet 154 communicating with the second air inlet 142 is also provided on the control circuit board 15, a third air passage 171 communicating with the second air passage 153 is provided on the receiving seat 17, a pressure sensor 155 coupled to the control circuit board 15 is provided at the connection between the second air passage 153 and the third air passage 171, and a fourth air inlet 172 communicating with the third air inlet 154 is also provided on the receiving seat 17; a fifth air inlet 26 is provided at the bottom of the atomizing body 2, and the fifth air inlet 26, the fourth air inlet 172 and the third air passage 171 are all communicating.

[0040] It should be added that the air pressure sensor 155 can convert the gas pressure flowing from the second air vent 153 to the third air vent 171 into electrical signals of different intensities. The control circuit board 15 controls the power supply unit 1 to cut off and open the circuit to the atomizing unit 2 according to the different intensities of the electrical signals. In some embodiments, the control circuit board 15 is provided with a preset value for the electrical signal intensity. If the intensity of the transmitted electrical signal is higher than the preset value, the power supply unit 1 is controlled to supply power to the atomizing unit 2; if the intensity of the transmitted electrical signal is lower than the preset value, the power supply unit 1 is controlled to stop supplying power to the atomizing unit 2.

[0041] Preferably, the first air inlet 131 is divided into multiple holes, and the base 13 is provided with an adjustment key 133 that can be slid to cover or expose a number of holes, thereby achieving precise control over the effective flow area of ​​the first air inlet 131. Specifically, there are two holes. When the adjustment key 133 is slid to the initial position, both holes are fully exposed, corresponding to the maximum air intake flow rate; when the adjustment key 133 covers a single hole, the air intake flow rate is halved; when the adjustment key 133 completely covers both holes, the first air inlet 131 is completely blocked.

[0042] When using this atomizer and adjusting the adjustment key 133 to expose at least one through hole 143, the user can inhale through the mouthpiece 22. At this time, external gas enters from the first air inlet 131, and then the external gas is split into two airflows, which enter the second air inlet 142 and the first air passage 141 respectively. Then the two airflows enter the third air inlet 154 and the second air passage 153 opened on the control circuit board 15 respectively, and then enter the fourth air inlet 172 and the third air passage 171 opened on the receiving seat 17 respectively. Then the two airflows merge and enter the fifth air inlet 26 at the bottom of the atomizing body 2. Finally, they enter the airflow channel and mix with the aerosol, which is then inhaled by the user from the mouthpiece 22, thus allowing the user to inhale the aerosol.

[0043] When the airflow enters the second air passage 153 and flows to the air pressure sensor 155, the control circuit board 15 controls the circuit breaking and opening of the atomizing body 2 according to the electrical signal sent by the air pressure sensor 155, thereby controlling the opening and closing of the heating element in the atomizing body 2. Then the airflow flows out from the air pressure sensor and enters the third air passage 171.

[0044] It's important to note that the air intake volume significantly affects the air-to-liquid mixing ratio, thus impacting the atomization effect, taste, and overall performance of the atomizer. A larger air intake increases airflow, diluting the aerosol and reducing its concentration in the air, while also accelerating the wear and tear on the atomizer body 2. Conversely, a smaller air intake reduces airflow, increasing the aerosol concentration in the air and extending its lifespan. Therefore, our atomizer employs a graded orifice adjustment structure, with orifices 0, 1, and 2 open, enabling precise flow control at three levels to meet diverse usage needs.

[0045] Preferably, such as Figure 6 As shown, a connecting cylinder 176 and a mounting cylinder 175 are provided at the bottom of the receiving base 17. The connecting cylinder 176 is located at the bottom of the fourth air inlet 172. A hollow column extends from the outer edge of the second air inlet 142 on the transition block 14 toward the receiving base 17. The hollow column passes through the third air inlet 154 on the control circuit board 15 and is inserted into the mounting cylinder 175, thereby enabling communication between the second air inlet 142 and the fourth air inlet 172. The mounting cylinder 175 is located at the bottom of the third air passage 171. The air pressure sensor 155 is located on the side of the control circuit board 15 facing the mounting cylinder 175, and the bottom of the air pressure sensor 155 is connected to the second air passage 153. The mounting cylinder 175 is used to install the air pressure sensor 155, thereby enabling the air pressure sensor 155 to be installed between the second air passage 153 and the third air passage 171.

[0046] The above is only used to illustrate the technical solution of this utility model and not to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
