Description

Technical Field

[0001] The present application relates to the technical field of aerosol atomization, and in particular to an atomizer, an atomization device and an atomizer housing. Background Art

[0002] When using an electronic vaping device, outside air flows into the device through the air inlet, where it is atomized and produces aerosol. After the device is used, the air and aerosol condense to form droplets that adhere to the device. These droplets accumulate over time, forming a liquid that flows around, making it easy for the liquid to leak from the air inlet, thus affecting the user experience. Utility Model Content

[0003] The present application provides an atomizer, an atomizing device and an atomizer housing, which aim to solve the technical problem that the air inlet of an electronic atomizing device is prone to leaking liquid.

[0004] In some embodiments of the present application, a nebulizer is provided, comprising:

[0005] The housing has a receiving cavity and an air inlet and a suction nozzle connected to the receiving cavity;

[0006] an atomizing assembly disposed in the accommodating chamber, wherein an outlet of the atomizing assembly is in communication with the mouthpiece, and the atomizing assembly is used for atomizing and generating an aerosol;

[0007] an air inlet member connected to the housing, the air inlet member having an air inlet channel, one end of the air inlet channel communicating with the air inlet hole, and the other end of the air inlet channel communicating with the inlet airflow of the atomizing assembly; and

[0008] An isolation component is arranged on the air intake channel, and the isolation component has an elastic isolation part. When the air pressure in the shell is negative, the elastic isolation part is deformed to connect the airflow in the air intake channel; when the air pressure inside and outside the shell is balanced, the elastic isolation part is reset and blocks the airflow connection in the air intake channel.

[0009] In some embodiments, the housing includes an upper shell and a lower shell;

[0010] The upper shell is connected to the lower shell and encloses the accommodating cavity. The air inlet is provided in the upper shell, and the height of the air inlet from the lower shell is greater than the height of the atomizing assembly from the lower shell.

[0011] In some embodiments, the air inlet is located at the top of the upper shell;

[0012] At least a portion of the air inlet member extends from the top of the upper shell along the axial direction of the air inlet hole toward the lower shell, and an end of the air inlet member away from the air inlet hole is close to the lower shell.

[0013] In some embodiments, the atomizer further comprises a sealing member disposed within the housing;

[0014] The sealing member separates the accommodating cavity into a liquid storage bin and an air inlet bin. The atomizing assembly is arranged in the liquid storage bin. One end of the air inlet member away from the air inlet hole passes through the sealing member and is connected to the air inlet bin. The inlet of the atomizing assembly is connected to the air inlet bin.

[0015] In some embodiments, an end of the air inlet member away from the air inlet hole and an inlet of the atomization assembly are spaced apart in the air inlet bin.

[0016] In some embodiments, the isolation assembly is disposed at an end of the air inlet member away from the air inlet hole.

[0017] In some embodiments, the atomizer further comprises a liquid absorbing member disposed in the air inlet bin;

[0018] The liquid absorbing component is arranged on the lower shell, and the liquid absorbing component is arranged opposite to the isolation component.

[0019] In some embodiments, the sealing member is located inside the upper shell and close to the lower shell;

[0020] The upper shell and the air inlet component are made of transparent material.

[0021] In some embodiments, the isolation assembly includes an isolation member and a fixing seat;

[0022] The elastic isolation portion is arranged on the isolation member, and forms a hollow portion when the elastic isolation portion is deformed to connect the airflow of the air intake channel. The fixing seat is connected to the air intake member, and the isolation member is fixed between the fixing seat and the air intake member.

[0023] Some embodiments of the present application further provide an atomizing device, comprising:

[0024] The atomizer of any of the above embodiments; and

[0025] A power supply component is electrically connected to the atomizer, and the power supply component is used to supply power to the atomizer.

[0026] Some embodiments of the present application further provide an atomizer housing, comprising:

[0027] The housing has a receiving cavity and an air inlet and a suction nozzle connected to the receiving cavity;

[0028] an air intake member connected to the housing, the air intake member having an air intake channel, one end of the air intake channel communicating with the air intake hole, and the other end of the air intake channel being disposed in the accommodating cavity; and

[0029] An isolation component is arranged on the air intake channel, and the isolation component has an elastic isolation part. When the air pressure in the shell is negative, the elastic isolation part is deformed to connect the airflow in the air intake channel; when the air pressure inside and outside the shell is balanced, the elastic isolation part is reset and blocks the airflow connection in the air intake channel.

[0030] According to the atomizer of the above embodiment, when a user uses the atomizer, the air pressure within the accommodating chamber can be negatively pressurized through the mouthpiece. At this point, the elastic isolating portion can deform under the action of the negative pressure, allowing the airflow in the air inlet passage to flow through the air inlet passage and into the atomizing assembly for atomization. When the user stops using the atomizer, the air pressure inside and outside the housing is balanced, and the elastic isolating portion can be reset under its elastic action to block the airflow in the air inlet passage, thereby preventing liquid formed by condensation in the housing from flowing out of the air inlet opening through the air inlet passage.

[0031] Furthermore, since the air and aerosol heated by the atomizer assembly in the housing are both hot air, the outer wall of the air inlet element blocks the rising hot air flow, preventing it from converging directly at the air inlet and condensing into liquid before flowing out of the housing. The condensed liquid flows into the housing under the action of gravity, minimizing the risk of liquid flowing out of the air inlet and improving the user experience.

Therefore, the specification and drawings are only for the purpose of clearly describing a particular embodiment and do not imply a required composition and / or sequence.

[0041] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0042] The present application provides an atomizing device, such as Figure 1 and Figure 2 As shown, the atomizing device may include an atomizer 1 and a power supply assembly 2. The atomizer 1 is electrically connected to the power supply assembly 2, and the power supply assembly 2 can supply power to the atomizer 1 to cause the atomizer 1 to atomize and generate an aerosol. The atomizing device may be configured in a box-shaped or elongated structure. The power supply assembly 2 may include components such as a battery and a circuit board. The atomizer 1 may be electrically connected to the circuit board, and the circuit board may be electrically connected to the battery.

[0043] In addition, if Figure 1As shown, the power supply assembly 2 can be arranged outside the atomizer 1, and the atomizer 1 can be detachably connected to the power supply assembly 2. For example, the atomizing device can also include a magnetic member 50, and the magnetic member 50 can be arranged on the atomizer 1, and the atomizer 1 and the power supply assembly 2 can be connected by the magnetic attraction of the magnetic member 50. Alternatively, the atomizer 1 and the power supply assembly 2 can also be detachably connected by plugging, snapping or screwing. In other embodiments, the power supply assembly 2 can also be arranged inside the atomizer 1 for supplying power to the atomizer 1, and the power supply assembly 2 is non-detachably connected to the atomizer 1. This application does not impose any special restrictions on the specific structure of the atomizer 1 and the power supply assembly 2.

[0044] In order to prevent the atomizer 1 from leaking liquid, the present application also provides an atomizer 1, such as Figures 2 to 5 As shown, the atomizer 1 may include an atomizer housing 10 and an atomizer assembly 20. The atomizer housing 10 may include a shell 11, an air inlet member 12 and an isolation assembly 13. The shell 11 has a receiving chamber 110 and an air inlet hole 111 and a mouthpiece 112 communicating with the receiving chamber 110. The atomizer assembly 20 is arranged in the receiving chamber 110, and the outlet of the atomizer assembly 20 is communicated with the mouthpiece 112. The atomizer assembly 20 can be used for atomization and generating aerosol. The air inlet member 12 is connected to the shell 11, and the air inlet member 12 has an air inlet hole 111 and a mouthpiece 112. Channel 120, one end of the air inlet channel 120 is connected to the air inlet hole 111, and the other end of the air inlet channel 120 is connected to the inlet airflow of the atomizer assembly 20; the isolation assembly 13 can be set on the air inlet channel 120, and the isolation assembly 13 has an elastic isolation portion 1310. When the air pressure in the shell 11 is negative pressure, the elastic isolation portion 1310 can be deformed to connect the airflow of the air inlet channel 120; when the air pressure inside and outside the shell 11 is balanced, the elastic isolation portion 1310 can be reset and block the airflow connection of the air inlet channel 120.

[0045] When the user uses the atomizer 1, the air pressure within the accommodating chamber 110 can be negatively pressurized through the mouthpiece 112. At this point, the elastic isolating portion 1310 can deform under the negative pressure, allowing the airflow in the air inlet channel 120 to flow through the air inlet channel 120 and into the atomizing assembly 20 for atomization. When the user stops using the atomizer 1, the air pressure inside and outside the housing 11 is balanced. The elastic isolating portion 1310 can be elastically reset and block the airflow in the air inlet channel 120, thereby preventing condensed liquid in the housing 11 from flowing out of the air inlet channel 120 and out of the air inlet hole 111.

[0046] Furthermore, since the air and aerosol heated by the atomizer assembly 20 in the housing 11 are both hot air, the outer wall of the air inlet member 12 can also block the hot air as it rises, thereby preventing the hot air from directly converging at the air inlet 111 and condensing into liquid and flowing out of the housing 11. The condensed liquid will flow into the housing 11 under the action of gravity, thereby minimizing the problem of liquid flowing out of the air inlet 111 and improving the user experience.

[0047] The atomizer 1 provided in this application can be used to atomize both solid aerosol products and liquid aerosol substrates. Regardless of whether the aerosol product or the aerosol substrate is atomized, the condensed liquid can be blocked by the air inlet member 12 and the isolation assembly 13, thereby preventing the liquid from flowing out of the air inlet 111. This application does not impose any particular restrictions on the atomizing material used in the atomizer 1.

[0048] In some embodiments, as Figures 2 to 4 As shown, the shell 11 may include an upper shell 113 and a lower shell 114; the upper shell 113 is connected to the lower shell 114 and encloses a accommodating cavity 110, the air inlet 111 may be set in the upper shell 113, and the height of the air inlet 111 from the lower shell 114 may be greater than the height of the atomizer assembly 20 from the lower shell 114.

[0049] Since the liquid formed after condensation will flow toward the lower shell 114 under the action of gravity, the height of the air inlet 111 from the lower shell 114 is set to be greater than the height of the atomizer assembly 20 from the lower shell 114, so that the condensed liquid is not easy to flow out of the air inlet 111. The upper shell 113 and the lower shell 114 can be detachably connected by means of snap connection, plug connection or screw connection, so as to facilitate the installation of the atomizer assembly 20 into the outer shell 11. The present application does not impose any special restrictions on the connection structure between the upper shell 113 and the lower shell 114.

[0050] In some embodiments, as Figures 2 to 4 As shown, the air inlet 111 can be located at the top of the upper shell 113; at least part of the air inlet member 12 extends from the top of the upper shell 113 along the axial direction (aa axis direction) of the air inlet hole 111 toward the lower shell 114, and the end of the air inlet member 12 away from the air inlet hole 111 is close to the lower shell 114.

[0051] When the air inlet member 12 extends from the top of the upper shell 113 along the axial direction (aa axis direction) of the air inlet hole 111 toward the lower shell 114 and approaches the lower shell 114, the hot air flow of air and aerosol rises and is blocked by the air inlet member 12, making it difficult for the hot air flow to flow into the air inlet channel 120, thereby reducing the formation of condensed droplets in the air inlet channel 120. At the same time, the air inlet hole 111 is located at the top of the upper shell 113, which prevents the condensed liquid from flowing out of the outer shell 11 through the air inlet hole 111.

[0052] Among them, the air inlet member 12 can be a straight tube arranged along the aa axis direction, or it can be an L-shaped bend. When the air inlet member 12 is an L-shaped bend, a portion of the air inlet member 12 can be arranged along the aa axis direction, and the other portion can be bent toward the inlet of the atomization assembly 20, thereby increasing the flow path of the condensed liquid to prevent the condensed liquid from flowing out of the outer shell 11. In other embodiments, the air inlet hole 111 can also be arranged on the side wall of the upper shell 113, and the air inlet member 12 can also be set as a Z-shaped bend. This application does not impose any special restrictions on the specific location of the air inlet hole 111 and the specific shape of the air inlet member 12.

[0053] In some embodiments, the atomizer 1 may further include a sealing member 30 disposed in the outer shell 11; the sealing member 30 may separate the accommodating chamber 110 into a liquid storage tank 1101 and an air inlet tank 1102, the atomizing assembly 20 is disposed in the liquid storage tank 1101, and the end of the air inlet member 12 away from the air inlet hole 111 passes through the sealing member 30 and is connected to the air inlet tank 1102, and the inlet of the atomizing assembly 20 is connected to the air inlet tank 1102.

[0054] Thus, the liquid storage tank 1101 can be used to store aerosol substrate, and the seal 30 can separate gas and liquid within the accommodating chamber 110 to prevent the aerosol substrate from leaking into the air inlet tank 1102. The air inlet tank 1102 can be located at the bottom of the accommodating chamber 110, and the liquid storage tank 1101 can be located at the top of the accommodating chamber 110. In other embodiments, the liquid storage tank 1101 and the air inlet tank 1102 can also be located on either side of the accommodating chamber 110. This application does not impose any particular limitations on the specific locations of the liquid storage tank 1101 and the air inlet tank 1102.

[0055] In addition, the atomizing assembly 20 may include a heating element, a liquid guiding element and an atomizing tube, one end of the atomizing tube is connected to the suction nozzle 112, and the other end passes through the sealing element 30 and is connected to the air inlet bin 1102. A liquid inlet hole may be provided on the atomizing tube, and the liquid guiding element may be sleeved on the position of the liquid inlet hole in the atomizing tube to adsorb the aerosol matrix in the liquid storage bin 1101, and the heating element is sleeved in the liquid guiding element to heat and atomize the aerosol matrix. Among them, the liquid guiding element may be a liquid guiding cotton, and the heating element may be a heating wire or a heating net. Of course, the atomizing assembly 20 may also be a heating needle for atomizing solid aerosol products. The present application does not impose any special restrictions on the specific structure of the atomizing assembly 20.

[0056] In some embodiments, as Figure 2 As shown, one end of the air inlet member 12 away from the air inlet hole 111 can be spaced apart from the inlet of the atomizer assembly 20 in the air inlet bin 1102 .

[0057] By spacing the outlet of the air inlet member 12 and the inlet of the atomizer assembly 20 within the air inlet bin 1102, the distance of airflow communication between the air inlet member 12 and the atomizer assembly 20 can be increased, thereby allowing a portion of the hot air flow to condense into liquid in the channel between the air inlet member 12 and the atomizer assembly 20, thereby preventing the hot air flow from condensing entirely within the air inlet channel 120 and, in turn, preventing the liquid from flowing out of the air inlet hole 111. In addition, an air baffle can be added to the channel between the air inlet member 12 and the atomizer assembly 20 to make the path of the hot air flow a tortuous path, thereby increasing the path length of the hot air flow, thereby helping to reduce the condensed liquid formed at the outlet of the air inlet member 12.

[0058] In some embodiments, as Figure 2 and Figure 3 As shown, the isolation assembly 13 can be disposed at an end of the air inlet member 12 away from the air inlet hole 111 .

[0059] In this way, the hot air flow can be blocked at the end of the air inlet member 12 away from the air inlet hole 111, preventing the hot air flow from flowing into the air inlet passage 120 and condensing to form liquid. In other embodiments, the isolation assembly 13 can also be disposed within the air inlet passage 120. The specific location of the isolation assembly 13 is not particularly limited in this application.

[0060] In some embodiments, as Figure 2 As shown, the atomizer 1 may further include a liquid absorbing member 40 disposed in the air inlet bin 1102 ; the liquid absorbing member 40 may be disposed in the lower shell 114 , and the liquid absorbing member 40 may be disposed opposite to the isolation assembly 13 .

[0061] When the hot air condenses into liquid within the air inlet chamber 1102, the liquid absorbing element 40 absorbs the liquid, preventing it from flowing into the air inlet member 12. Because the liquid absorbing element 40 is positioned opposite the isolation assembly 13, when external air flows into the air inlet chamber 1102 from the air inlet passage 120, the liquid absorbing element 40 does not block the air. However, when the condensed liquid flows out of the air inlet passage 120, it will be first absorbed by the liquid absorbing element 40. Thus, the atomizer 1 of the present application can effectively prevent condensed liquid from flowing out of the housing 11 while ensuring air supply.

[0062] In some embodiments, the sealing member 30 may be located inside the upper shell 113 and close to the lower shell 114 ; the upper shell 113 and the air inlet member 12 may be made of a transparent material.

[0063] The transparent upper shell 113 and air inlet 12 facilitate the user's observation of the remaining aerosol matrix in the liquid storage chamber 1101 and enhance the aesthetic appearance of the atomizer 1, thereby improving the user experience. When the sealing member 30 is located within the upper shell 113 and close to the lower shell 114, condensed liquid or mist in the air inlet chamber 1102 can form on the bottom of the outer shell 11, thereby preventing the liquid or mist from adhering to the upper shell 113 and affecting the transparent appearance of the upper shell 113.

[0064] In some embodiments, as Figure 4 and Figure 5 As shown, the isolation assembly 13 may include an isolation piece 131 and a fixing seat 132; the elastic isolation portion 1310 is arranged on the isolation piece 131, and the elastic isolation portion 1310 forms a hollow portion when deformed to allow the airflow of the intake channel 120 to be connected, the fixing seat 132 is connected to the intake piece 12, and the isolation piece 131 can be fixed between the fixing seat 132 and the intake piece 12.

[0065] For example, the isolator 131 can be configured as a circular silicone sheet, the fixing seat 132 can be configured as a cylindrical cover, the isolator 131 can be installed in the fixing seat 132, and the fixing seat 132 can be sleeved on the end of the air inlet member 12 away from the air inlet hole 111. The elastic isolation portion 1310 can be a plurality of fan-shaped springs formed on the isolator 131. When the air pressure inside the shell 11 is negative, the plurality of fan-shaped springs can be bent and deformed at the center position so that the isolator 131 forms a hollow channel, thereby connecting the airflow of the air inlet channel 120. When the air pressure inside and outside the shell 11 is balanced, the plurality of fan-shaped springs can be reset under the elastic action to block the airflow connection of the air inlet channel 120.

[0066] In other embodiments, the isolation member 131 may also be configured as a structure in which a spring plate and a barrier plate are connected. For example, the barrier plate can block the air inlet passage 120 under the elastic force of the spring plate. When the air pressure within the housing 11 is negative, the barrier plate overcomes the elastic force of the spring plate and moves away from the air inlet passage 120, thereby allowing airflow in the air inlet passage 120 to flow freely. This application does not impose any particular limitations on the specific structure of the isolation member 131.

[0067] The above examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. Those skilled in the art of the present invention can make some simple deductions, modifications or substitutions based on the concept of the present invention.
