Description

Technical Field

[0001] This utility model belongs to the field of atomization technology, and in particular relates to an atomizer and an electronic atomization device. Background Technology

[0002] Current atomizers typically place the microphone inside the airflow channel. The microphone detects minute pressure changes caused by the gas passing through the airflow channel. When a user inhales from the atomizer, the airflow impacts the microphone, which converts this pressure change into an electrical signal, triggering the atomizer coil to heat and atomize the aerosol. However, current atomizers have low atomization efficiency. Increasing atomization efficiency would increase the amount of aerosol condensation in the airflow channel, potentially causing the condensed aerosol to flow into the microphone and malfunction. Utility Model Content

[0003] The purpose of this invention is to provide an atomizer and an electronic atomizing device, which aims to solve the technical problem that the condensation of aerosol in the air intake channel of the current atomizer may cause the microphone to fail.

[0004] This utility model is implemented as follows: Firstly, it provides an atomizer, including a housing, an atomizing core, and a microphone;

[0005] The housing has an air intake channel, an atomizing channel, and an activation channel. There are multiple atomizing channels, all of which are connected to the air intake channels. The activation channel passes through the housing and is isolated from each of the atomizing channels. The number of atomizing cores is the same as the number of atomizing channels. Each atomizing core is disposed in one of the atomizing channels. The microphone is disposed in the activation channel.

[0006] As some possible embodiments of the first aspect, each of the atomizing air passages and the starting air passages extend in the same direction, and each of the atomizing air passages is symmetrically arranged around the starting air passage.

[0007] As some possible embodiments of the first aspect, the housing includes a nozzle, a peripheral shell, and a bottom shell. The peripheral shell forms a tubular structure. The bottom shell and the nozzle respectively cover the openings at both ends of the peripheral shell. The nozzle forms a plurality of first air intake channels and a second air intake channel. Each of the first air intake channels is connected to a certain atomizing air channel, and the second air intake channel is connected to the activation air channel.

[0008] As some possible embodiments of the first aspect, the bottom shell is provided with a start-up air inlet, which is connected to the start-up air passage.

[0009] As some possible embodiments of the first aspect, the peripheral shell is provided with an atomizing air inlet, which is connected to the air inlet passage.

[0010] As some possible embodiments of the first aspect, the air intake duct and the atomizing duct are arranged side by side, and the air intake duct and the atomizing duct are connected to each other on the same side.

[0011] As some possible embodiments of the first aspect, the atomizer further includes a gas adjustment switch movably connected to the housing and used to adjust the opening of the atomizing air inlet.

[0012] As some possible embodiments of the first aspect, the gas regulating switch has at least two gas regulating holes, the gas regulating switch is slidably connected to the housing and can slide between a blocked position, a low position and a high position, when the gas regulating switch is in the blocked position the gas regulating switch blocks the atomizing air inlet, when the gas regulating switch is in the low position at least one of the gas regulating holes is misaligned with the atomizing air inlet and at least one of the gas regulating holes is connected to the atomizing air inlet, when the gas regulating switch is in the high position all the gas regulating holes are connected to the atomizing air inlet.

[0013] As some possible embodiments of the first aspect, the gas regulating switch is provided with a gas regulating rod, which passes through the atomizing air inlet and extends out of the housing.

[0014] As some possible embodiments of the first aspect, the housing also forms a liquid storage cavity and an injection hole extending into the liquid storage cavity, the liquid storage cavity being connected to the atomizing air passage, and the atomizer further includes an injection plug, the injection plug being rotatably connected to the housing and being able to rotate between a closed position covering the injection hole and an open position avoiding at least part of the injection hole.

[0015] In a second aspect, an electronic atomizing device is provided, including the atomizer provided in the above embodiments.

[0016] The technical advantages of this invention compared to existing technologies are as follows: When the user inhales, an airflow is formed within the activation airway. The microphone senses the pressure change within the activation airway and sends a pressure signal to the circuit board. The circuit board then controls the atomizing core to activate based on this pressure signal, heating and atomizing the aerosol matrix. Simultaneously, the user's inhalation allows external air to enter multiple atomizing airways through the intake airway, ensuring that the atomized aerosol matrix in each atomizing airway is brought into the user's mouth. This atomizer improves atomization efficiency by setting multiple atomizing airways and an atomizing core number commensurate with the number of atomizing airways. By isolating the activation airway containing the microphone from the atomizing airways, it prevents the atomized aerosol matrix from contacting the microphone after condensation into liquid, thus avoiding microphone damage.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] This utility model provides an electronic atomizing device and an atomizer. The electronic atomizing device includes the atomizer and a main unit. The main unit is detachably connected to the atomizer. The main unit is equipped with a battery and a circuit board. The battery is electrically connected to the circuit board, and the circuit board is electrically connected to the atomizer. The battery is used to power the atomizer, and the circuit board is used to control the atomizer to work.

[0028] Please see Figure 1 and Figure 2 The atomizer includes a housing 10, an atomizing coil 20, and a microphone (not shown in the figure).

[0029] The housing 10 has an air intake channel 101, an atomizing channel 102, and an activation channel 103. Multiple atomizing channels 102 are provided, all of which are connected to the air intake channels 101. The number of atomizing cores 20 is the same as the number of atomizing channels 102, and each atomizing core 20 is disposed within a specific atomizing channel 102. The activation channel 103 penetrates the housing 10 and is isolated from each atomizing channel 102. The microphone is disposed within the activation channel 103. The atomizing cores 20 and the microphone are electrically connected to the circuit board.

[0030] When the user inhales, an airflow is created within the activation airway 103. The microphone senses the pressure change within the activation airway 103 and sends a pressure signal to the circuit board. The circuit board then controls the atomizing core 20 to activate based on this pressure signal, heating and atomizing the aerosol matrix. Simultaneously, the user's inhalation allows external air to enter multiple atomizing airways 102 through the intake airway 101, bringing the atomized aerosol matrix from each atomizing airway 102 into the user's mouth. This atomizer improves atomization efficiency by using multiple atomizing airways 102 and an equivalent number of atomizing cores 20. Isolating the activation airway 103 (containing the microphone) from the atomizing airways 102 prevents the atomized aerosol matrix from condensing into liquid and contacting the microphone, thus avoiding microphone damage.

[0031] Please see Figure 2 In some embodiments, each atomizing airway 102 and the activation airway 103 extends in the same direction to reduce the space occupied by the housing 10 in the thickness direction. Each atomizing airway 102 is symmetrically arranged around the activation airway 103 for ease of manufacturing. Simultaneously, when the user inhales, the airflow velocity in the activation airway 103 is relatively high to improve the microphone's sensitivity. This symmetrical arrangement can be either axially symmetrical about the periphery of the activation airway 103 or centrally symmetrical; no limitation is made here. In the illustrated embodiment, two atomizing airways 102 are provided, and the central axes of the two atomizing airways 102 and the activation airway 103 can be located on the same plane to save space.

[0032] Please see Figure 2 In some embodiments, the housing 10 includes a nozzle 12, a peripheral shell 11, and a bottom shell 13. The peripheral shell 11 forms a tubular structure with openings at both ends. The bottom shell 13 and the nozzle 12 respectively cover the openings at both ends of the peripheral shell 11 to form an installation cavity together with the peripheral shell 11. The starting air passage 103 and the atomizing air passage 102 are both disposed within the installation cavity. A liquid storage cavity 104 is also formed within the housing 10. Specifically, a partition 14 is disposed within the installation cavity. The partition 14 serves as the boundary between the air inlet passage 101 and the liquid storage cavity 104. The liquid storage cavity 104 is used to store the aerosol matrix.

[0033] Optionally, the nozzle 12 and the peripheral shell 11 can be integrally molded to improve structural strength and prevent aerosol matrix from flowing out at the connection between the nozzle 12 and the peripheral shell 11.

[0034] Please see Figure 2In some embodiments, the nozzle 12 has a plurality of first air intake channels 121 and a second air intake channel 122. Each first air intake channel 121 is connected to an atomizing air channel 102, and the second air intake channel 122 is connected to an activation air channel 103. When using the nozzle, the user can put it into their mouth so that airflow is generated simultaneously in the atomizing air channel 102 and the activation air channel 103.

[0035] Optionally, each of the first intake channels 121 and the second intake channels 122 can be connected to each other to increase the airflow.

[0036] Optionally, the atomizing shell 10a forming the atomizing airway 102 and the cavity wall of the mounting cavity, as well as the starting shell 10b forming the starting airway 103 and the cavity wall of the mounting cavity, are sealed by a sealing plug 15, which can separate the nozzle 12 from the liquid storage cavity 104.

[0037] The atomizing shell 10a forming the atomizing airway 102 is also sealed to the channel wall of the first intake channel 121 through the sealing plug 15, and the starting shell 10b forming the starting airway 103 is also sealed to the channel wall of the second intake channel 122 through the sealing plug 15.

[0038] Optionally, the sealing plug 15 covers the opening of the connecting nozzle 12 of the peripheral shell 11. The sealing plug 15 is made of an elastic material, such as rubber. The sealing plug 15 has two first connecting holes 151 and one second connecting hole 152. The atomizing shell 10a passes through the first connecting hole 151 and is press-fitted with the wall of the first connecting hole 151. The actuating shell 10b passes through the second connecting hole 152 and is press-fitted with the wall of the second connecting hole 152.

[0039] Optionally, the atomizing shell 10a forming the atomizing airway 102 is cylindrical and has multiple liquid inlet holes, which can be arranged circumferentially around the atomizing shell 10a. The atomizing shell 10a serves as the boundary between the atomizing airway 102 and the liquid storage chamber 104, and the aerosol matrix in the liquid storage chamber 104 can flow into the atomizing airway 102 through the liquid inlet holes. The atomizing core 20 includes absorbent cotton 21 and heating wire 22. The absorbent cotton 21 is connected to the inner wall of the atomizing shell 10a and blocks the liquid inlet holes. The absorbent cotton 21 can absorb the aerosol matrix entering the atomizing airway 102, and the heating wire 22 is used to heat the absorbent cotton 21 to atomize the aerosol matrix in the absorbent cotton 21.

[0040] Please see Figure 2In some embodiments, the bottom shell 13 is provided with a start-up air inlet 105, which is connected to the start-up air passage 103. When the bottom shell 13 is installed on the peripheral shell 11, the start-up air inlet 105 can be connected to the air inlet of the start-up air passage 103 so that the start-up air passage 103 passes through the shell 10, which facilitates assembly.

[0041] The starting air passage 103 extends in a straight line, and the starting air inlet 105 can be located on the extension path of the axis of the starting air passage 103 to shorten the flow path of the airflow in the starting air passage 103, thereby reducing the possibility of blockage of the starting air passage 103.

[0042] Please see Figure 2 In some embodiments, the peripheral shell 11 has an atomizing air inlet 106, which is connected to the air intake channel 101. The air intake channel 101 and the atomizing air channel 102 are arranged side by side, and the ends of the air intake channel 101 and the atomizing air channel 102 are connected on the same side. In this way, the air intake channel 101 and the atomizing air channel 102 together form a U-shaped air channel. The atomizing air inlet 106 avoids the bottom shell 13, which can prevent oil leakage near the bottom shell 13 and improve the user experience.

[0043] Please see Figure 2 In some embodiments, the atomizer further includes a gas flow control switch 30, which is movably connected to the housing 10 and functions to adjust the opening of the atomizing air inlet 106. The gas flow control switch 30 can not only open or close the atomizing air inlet 106 by moving relative to the housing 10, but also adjust its position to suit user needs. During use, the user can adjust the airflow by regulating the gas flow control switch 30, thereby adjusting the amount of mist and flavor according to their preferences. The connection between the gas flow control switch 30 and the housing 10 can be, but is not limited to, a rotating connection, a sliding connection, or a flexible connection.

[0044] Optionally, the gas regulating switch 30 is slidably connected to the housing 10. Specifically, the gas regulating switch 30 is slidably connected to the peripheral housing 11 and can slide back and forth along the direction from the nozzle 12 to the bottom housing 13. The gas regulating switch 30 can be located within the air intake channel 101 and slides in cooperation with the partition 14. The cross-sectional area of ​​the gas regulating switch 30 is larger than that of the atomizing air intake hole 106, so that the atomizing air intake hole 106 can be completely blocked when the atomizer is not in use. This not only prevents air intake but also prevents the condensed aerosol matrix in the U-shaped airway from flowing out of the atomizing air intake hole 106.

[0045] Optionally, the vapor control switch 30 has at least two vapor control holes 301 and can slide between a blocked position, a low position, and a high position. The low position can be located between the blocked position and the high position. When the vapor control switch 30 is in the blocked position, it blocks the atomizing air inlet 106, thus closing the atomizing air inlet 106. When the atomizer is not in use, the vapor control switch 30 can be moved to the blocked position. When the vapor control switch 30 is in the low position, at least one vapor control hole 301 is misaligned with the atomizing air inlet 106, and at least one vapor control hole 301 is connected to the atomizing air inlet 106. In this case, the air intake of the atomizing air inlet 106 is relatively small. When the user does not require a large vapor output or a strong flavor, the switch can be adjusted to the low position. When the gas adjustment switch 30 is in the high position, all the gas adjustment holes 301 are connected to the atomizing air inlet hole 106. That is, the projection of the atomizing air inlet hole 106 on the peripheral shell 11 covers the projection of all the gas adjustment holes 301 on the peripheral shell 11. At this time, the air intake of the atomizing air inlet hole 106 is large. When the user needs a larger amount of mist or a stronger taste, the adjustment switch can be adjusted to the high position.

[0046] It should be noted that the multiple air adjustment holes 301 can be the same size, or at least one of them can be different in size from the others. There are no restrictions here, and adjustments can be made according to the specific needs. Of course, when there are more than three air adjustment holes 301, multiple positions can be used as the low-speed position. The air intake volume will vary depending on the number of air adjustment holes 301 connected to the atomizing air inlet 106, and this can be adjusted according to the specific needs.

[0047] In other embodiments, the air regulating switch 30 may not have an air regulating hole 301. Instead, the air intake volume can be adjusted by adjusting the area of ​​the blockage of the atomizing air intake hole 106 relative to the housing 10. This is not a limitation.

[0048] Please see Figure 2 In some embodiments, the gas regulating switch 30 is provided with a gas regulating rod 31, which passes through the atomizing air inlet 106 and extends out of the housing 10. The gas regulating rod 31 facilitates the user's operation of the gas regulating switch 30. The user can drive the gas regulating switch 30 to move its position by moving the end of the gas regulating rod 31 that extends out of the housing 10, so as to adjust the atomizing air inlet 106 to the required opening degree.

[0049] Please see Figure 2In some embodiments, the housing 10 also has an injection hole 107 extending into the liquid storage chamber 104, through which the atomizer can inject the aerosol matrix into the liquid storage chamber 104. The atomizer also includes an injection plug 40, which is movably connected to the housing 10 and can move between a closed position covering the injection hole 107 and an open position that avoids at least part of the injection hole 107. When it is necessary to inject the aerosol matrix into the liquid storage chamber 104, the injection plug 40 can be moved to the open position so that the aerosol matrix is ​​injected into the liquid storage chamber 104 through the injection hole 107. After the aerosol matrix injection operation is completed, the injection plug 40 can be moved to the closed position to prevent aerosol matrix leakage.

[0050] Optionally, the injection plug 40 is rotatably connected to the housing 10 to prevent the injection plug 40 from being lost.

[0051] Optionally, the injection plug 40 is made of an elastic material, such as rubber. A limiting groove 108 is provided on the outer wall of the peripheral shell 11. The injection hole 107 can be provided at the bottom of the limiting groove 108. The injection plug 40 is adapted to the limiting groove 108. When the limiting groove 108 is received in the limiting groove 108, it is in the closed position. At this time, the limiting groove 108 can limit the injection plug 40 and reduce the height of the injection plug 40 protruding from the outer wall of the peripheral shell 11, so as to prevent the injection plug 40 from being lifted or displaced due to accidental contact.

[0052] In order to facilitate opening the injection plug 40, the cross-sectional dimension of the limiting groove 108 can be larger than the cross-sectional dimension of the injection plug 40. When the injection plug 40 is housed in the limiting groove 108, the gap between the injection plug 40 and the groove wall of the limiting groove 108 allows a finger to be inserted to pry out the injection plug 40.

[0053] Optionally, the bottom of the limiting groove 108 may also be provided with a rotating hole 109, and the injection plug 40 is provided with a rotating shaft 41 and a limiting post 42. The rotating shaft 41 is rotatably connected to the rotating hole 109, and the limiting post 42 can be inserted into the injection hole 107 when the injection plug 40 is in the closed position, so as to further limit the injection plug 40. When it is necessary to move the limiting post 42 to the open position, the limiting post 42 can be pulled out from the injection hole 107 first, and then the injection plug 40 can be rotated so that the injection plug 40 can avoid the injection hole 107 axially.

[0054] The rotating shaft 41 can also be made of an elastic material, such as rubber. In this way, when installing the rotating shaft 41, the rotating shaft 41 can be inserted into the rotating hole 109 through the elastic deformation of the rotating shaft 41, which facilitates assembly.

[0055] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
