Background

Detailed Description

In order that the utility model may be readily understood, a more particular description thereof will be rendered by reference to specific embodiments that are illustrated in the appended drawings. The specific examples are intended to be illustrative of the utility model and are not intended to be limiting. In addition, for convenience of description, only some, but not all of the structures related to the present utility model are shown in the drawings.

The embodiment of the utility model provides an electronic atomization device. Referring to fig. 2, the electronic atomization device 100 includes a liquid storage chamber 110, a ventilation channel 120, a valve body structure 130, and a heating element 140.

The reservoir 110 is used to store a liquid matrix. The liquid matrix may comprise, for example, one or more of the components glycerol, propylene glycol, nicotine formulations, fragrances, flavoring additives, and the like, although other types of liquid matrices are also possible. The liquid storage cavity 110 has a first end a1 and a second end a2 opposite to each other in the longitudinal direction, and the first end a1 of the liquid storage cavity 110 is provided with a liquid outlet 111.

As shown in fig. 2, the heating element 140 is disposed adjacent to the first end a1 of the liquid storage cavity 110 and is in communication with the liquid outlet 111, and the heating element 140 is configured to atomize the liquid matrix to generate aerosol. The liquid matrix in the liquid storage cavity 110 flows from the liquid outlet 111 to the heating element 140, and the heating element 140 heats and atomizes the liquid matrix to form aerosol.

Referring to fig. 2, the ventilation channel 120 communicates ambient air with the second end of the reservoir 110 such that the ventilation channel 120 provides a passageway for ambient air to enter the reservoir 110. The ventilation channel 120 may be directly or indirectly connected to the outside air. For example, as shown in fig. 2, an atomization chamber 102 is provided in the electronic atomization device 100, the atomization chamber 102 is communicated with the outside air through an air inlet channel 182, and one end of the ventilation channel 120 is communicated with the atomization chamber 102, so that the ventilation channel 120 is indirectly communicated with the outside air. The nebulizing chamber 102 is used to provide a release space for aerosol generated by nebulizing a liquid matrix. In the embodiment of the present utility model, one end of the ventilation channel 120 is connected to the liquid storage chamber 110, and the other end is connected to the atomizing chamber 102. When the negative pressure generated in the liquid storage cavity 110 exceeds a certain value, air is introduced into the liquid storage cavity 110 through the air exchange channel 120 to complete the air exchange operation.

In the embodiment of the present utility model, since the ventilation channel 120 is connected to the second end a2 of the liquid storage cavity 110, so that external air enters the liquid storage cavity 110 from the second end a2 of the liquid storage cavity 110, ventilation is performed from the top of the liquid storage cavity 110, that is, from above the liquid matrix in the liquid storage cavity 110 into the liquid storage cavity 110, and away from the liquid outlet 111, such ventilation mode can avoid ventilation bubbles from entering the liquid outlet 111 to block the liquid outlet 111, thereby ensuring that the liquid outlet 111 is normally discharged, and the heating element 140 can obtain sufficient liquid matrix, so as to avoid dry burning and burning of the heating element 140.

The valve body structure 130 is disposed at the second end a2 of the liquid storage cavity 110, and the valve body structure 130 is used for controlling the on-off of the ventilation channel 120. The valve body structure 130 may be any valve body structure 130, and may be a pneumatic valve, an electric valve or an elastic valve that can be elastically deformed under the action of pressure difference, which is not limited herein.

In an embodiment of the present utility model, as shown in fig. 2, the valve body structure 130 is an elastic valve body structure. The elastic valve body structure (valve body structure 130) is used for closing the ventilation channel 120, and can open the ventilation channel 120 to allow external air to enter the liquid storage cavity 110 in response to the negative pressure change in the liquid storage cavity 110. Specifically, the valve body structure 130 can open the ventilation channel 120 when the differential pressure between the liquid storage cavity 110 and the external air is greater than a preset value, and close the ventilation channel 120 when the differential pressure between the liquid storage cavity 110 and the external air is less than or equal to the preset value. Referring to fig. 2, when the negative pressure generated in the liquid storage chamber 110 is excessively large, the differential pressure between the liquid storage chamber 110 and the external air is greater than a preset value, the air pressure in the ventilation channel 120 is greater than the air pressure in the liquid storage chamber 110, the valve body structure 130 is pushed upward, and the ventilation channel 120 is opened, so that air can be introduced into the liquid storage chamber 110 to perform ventilation operation. When the air pressure in the liquid storage chamber 110 rises to a certain degree, the valve body structure 130 is reset, and the ventilation channel 120 is closed again. The valve body structure 130 adopts an elastic valve body structure which can be controlled by pressure difference, and has simple structure, lower cost and convenient installation.

The valve body structure 130 may be disposed in the ventilation channel 120 or may be disposed at an end of the ventilation channel 120. In an embodiment of the present utility model, the valve body structure 130 is disposed at an end of the ventilation channel 120. As shown in fig. 3, the ventilation channel 120 includes a ventilation port 121 near the second end a2 of the liquid storage chamber 110, the valve body structure 130 can open or close the ventilation port 121, and the ventilation port 121 is opened or closed by the valve body structure 130 to control the on-off of the ventilation channel 120. The valve body structure 130 is arranged at the end part of the ventilation channel 120, and the ventilation opening 121 is opened or closed through the valve body structure 130 to realize the on-off of the ventilation channel 120, so that the installation is convenient, and the response of the valve body structure 130 to the pressure difference can be more sensitive.

As shown in fig. 2 and 4, the second end a2 of the reservoir 110 is open to facilitate filling of the reservoir 110 through the open second end a2. As shown in fig. 2, the electronic atomization device 100 further includes a sealing member 150, and the sealing member 150 is configured to seal the second end a2 of the liquid storage cavity 110. The valve body structure 130 may then be disposed on the seal 150. The sealing member 150 is made of elastic material such as rubber, the valve body structure 130 may be made of elastic material such as rubber, and the valve body structure 130 is integrally formed on the sealing member 150. It will be appreciated that the thickness of the valve body structure 130 is much smaller than the thickness of the main body portion of the sealing member 150, so that the elastic portion 131 is thinner and is easily deformed, thereby opening the ventilation channel 120 in response to the negative pressure change in the liquid storage chamber 110.

In other embodiments, the elastic portion 131 may be deformed easily by changing the material of the elastic portion 131 instead of changing the thickness of the elastic portion 131. The elastic portion 131 is designed to be more elastically deformable than the main body portion of the sealing member 150, for example.

As shown in fig. 3, in the embodiment of the present utility model, the valve body structure 130 includes an elastic portion 131 and a protrusion 132. The protrusion 132 extends from the elastic portion 131 toward the transfer port 121 so that the protrusion 132 can close the transfer port 121. The elastic part 131 is thin-walled, so that it can be elastically deformed under the action of pressure difference, and the driving protrusion 132 is separated from or near the ventilation opening 121.

In an embodiment of the present utility model, as shown in fig. 2, the transfer port 121 is oriented toward the second end of the reservoir 110 such that the transfer port 121 is opposite the seal 150. Thus, the opening and closing of the ventilation opening 121 can be controlled by the up-and-down movement of the protrusion 132 on the valve body structure 130, so that the arrangement and the formation of the valve body structure 130 are facilitated. As shown in fig. 3, only a thin portion needs to be provided as the elastic portion 131 in the sealing member 150.

As shown in fig. 7, the elastic portion 131 of the valve body structure 130 is a thin-walled connection arm, one end of which is connected to the main body portion of the seal 150, and the other end of which is connected to the protrusion 132. The connecting arm may be provided in plurality to promote stability when the protrusion 132 moves. The elastic portion 131 is provided in the shape of a connecting arm instead of a closed disk, which makes the elastic portion 131 more easily deformed.

In an embodiment of the present utility model, referring to fig. 2 and 4, the electronic atomization device 100 further includes a mounting base 160. The liquid storage chamber 110 and the ventilation channel 120 are provided in parallel on the mounting base 160, and the liquid storage chamber 110 and the ventilation channel 120 are formed on the mounting base 160 by integrally molding. The top of the reservoir 110 is configured to be open to facilitate filling of the reservoir 110.

As shown in fig. 2, the ventilation channel 120 extends longitudinally, and the ventilation channel 120 is immediately adjacent to the reservoir 110. The connection between the ventilation channel 120 and the liquid storage cavity 110 is in a contracted shape, so that a smaller ventilation opening 121 is formed on the inner wall of the liquid storage cavity 110, and the smaller size of the ventilation opening 121 can avoid liquid leakage. The liquid matrix cannot flow out of the transfer port 121.

In one embodiment, the transfer ports 121 have a diameter of 0.08 to 0.62mm. More specifically, the diameter of the transfer port 121 may be 0.1 to 0.5mm. The size of the transfer port 121 defined herein by the diameter parameter is in the case of a circular transfer port 121, it being understood that the transfer port 121 may be of other shapes of the same cross-sectional size. Such as rectangular, oval or irregular shapes, etc.

As shown in fig. 2, the top of the reservoir 110 extends above the ventilation channel 120 such that the inner wall of the reservoir 110 forms a transverse wall section 111 extending substantially transversely. As shown in fig. 2, the transverse wall section 111 is substantially parallel to the seal 150, and the transfer port 121 is arranged on the transverse wall section 111 such that the transfer port 121 is directed towards the seal 150.

As shown in fig. 2, the protrusion 132 of the valve body structure 130 may be configured in a spherical shape, so that the protrusion 132 is more fitted with the ventilation port 121, and the sealing effect is improved.

As shown in fig. 1 and 2, the electronic atomizing device 100 further includes a suction nozzle 170. A mouthpiece 170 is provided on the mounting base 160, and a user sucks the atomized aerosol through the mouthpiece 170. As shown in FIG. 2, the suction nozzle 170 presses against the seal 150, compressing the seal 150 against the mounting base 160. The suction nozzle 170 is provided with a clamping column 171, and the clamping column 171 extends from the suction nozzle 170 to the sealing member 150. The sealing member 150 is provided with a clamping hole 151 matched with the clamping post 171, and the valve body structure 130 is arranged in the clamping hole 151 or at one end of the clamping hole 151. The cooperation of the clamping post 171 and the clamping hole 151 provided on the suction nozzle 170 and the sealing member 150 not only facilitates the positioning of the suction nozzle 170 and the sealing member 150, but also facilitates the reduction of the thickness of the elastic portion 131 of the valve body structure 130 by utilizing the depth of the clamping hole 151, and the thin-wall elastic portion 131 can be formed while the clamping hole 151 is formed on the sealing member 150.

In addition, the engagement of the locking pin 171 and the locking hole 151 ensures the sealability of the sealing member 150. Even if the elastic part 131 of the valve body structure 130 is provided with a plurality of hollowed-out holes, the sealing performance can be well ensured. For example, the elastic portion 131 is a connecting arm, as shown in fig. 7, so that a hollow hole b is inevitably formed between the connecting arms or between the connecting arm and the main body portion of the sealing member 150. In the embodiment of the present utility model, as shown in fig. 2, the engagement between the clamping post 171 and the clamping hole 151 is provided, and the clamping post 171 and the clamping hole 151 can be in interference fit to ensure sealing, so that even if the hollow hole exists in the elastic portion 131, sealing failure and leakage cannot occur.

With continued reference to fig. 2, the end of the clamping post 171 is spaced from the valve body structure 130 to form a deformation space for deformation of the valve body structure 130. When the ventilation channel 120 lifts up the valve body structure 130, a certain space is required above the valve body structure 130 to allow the valve body structure 130 to move upwards to deform. Therefore, a certain interval is provided between the valve body structure 130 and the end of the clamping post 171 to provide the deformation space.

As shown in fig. 5, the mounting base 160 is provided with a mounting chamber 161 and a battery chamber 162. The mounting chamber 161 and the liquid storage chamber 110 are sequentially disposed in the longitudinal direction, and the battery chamber 162 is disposed at one side of the mounting chamber 161 and the liquid storage chamber 110 in the lateral direction. Referring to fig. 2, a battery 101 is installed in the battery chamber 162. The battery 101 is used to power the heating element 140. As shown in fig. 5, the space between the reservoir chamber 110 and the battery chamber 162 may be used to provide a ventilation channel 120.

The heating member 140 is installed from the installation cavity 161 to below the liquid outlet 111. As shown in fig. 2, the electronic atomizing device 100 further includes a mounting base 180. Referring to fig. 2 and 5, the mount 180 is installed in the mounting chamber 161. As shown in fig. 2, the mounting base 180 is provided with a pole 181, the pole 181 is in contact with the heating element 140, and the pole 181 tightly pushes the heating element 140 towards the liquid outlet 111, so as to prevent the heating element 140 from falling down.

As shown in fig. 2, the heating element 140 is spaced from the mounting block 180 to form the atomizing chamber 102. One side of the heating element 140 is communicated with the liquid outlet 111, and the other side faces the atomizing cavity 102. The side of the heating element 140 in communication with the liquid outlet 111 is for absorbing a liquid matrix, and the side of the heating element 140 facing the nebulizing chamber 102 is for nebulizing the liquid matrix to form an aerosol. The atomizing chamber 102 communicates with the ambient air. One end of the ventilation channel 120 is communicated with the atomizing cavity 102, and the other end is communicated with the liquid storage cavity 110.

Referring to fig. 3 and 4, an air outlet duct 163 is also provided on the mounting base 160. As shown in fig. 3, the mounting base 180 is provided with an air intake passage 182. An air inlet 103 is provided at the bottom of the electronic atomizing device 100. The atomizing chamber 102 communicates with the outside air through the air intake passage 182 and the air intake port 103. Ambient air enters the mounting chamber 161 from the air inlet 103 and enters the nebulizing chamber 102 from the air inlet air channel 182, passes through the heating element 140, entrains the nebulized aerosol, and flows out of the air outlet air channel 163 to be sucked away from the mouthpiece 170 by a user.

As shown in fig. 5, the gas outlet airway 163 may be disposed adjacent to the ventilation channel 120, with the gas outlet airway 163 and the ventilation channel 120 being disposed using the space between the battery chamber 162 and the reservoir chamber 110.

As shown in fig. 4, two air outlet passages 163 may be provided, and the two air outlet passages 163 are respectively located at two sides of the ventilation channel 120, so as to avoid the air outlet passages 163 interfering with the ventilation channel 120, so that the overall structure is more compact, and the overall size of the whole electronic atomization device 100 is reduced.
