Technical Field

[0001] The present application relates to the field of atomization technology, and in particular to an electronic atomization device. Background Art

[0002] In the prior art, the air pressure inside the liquid storage chamber of a scalp atomizer device must be consistent with the external air pressure to ensure smooth atomization. During operation, as the atomized liquid in the liquid storage chamber is gradually consumed, gas must be replenished to balance the air pressure inside and outside the liquid storage chamber, allowing the device to continue atomizing.

[0003] However, the sealing performance of the liquid storage chamber of the scalp atomization drug delivery device in the related art is poor, so that the atomized liquid can easily penetrate out of the liquid storage chamber, while the external atmosphere cannot smoothly enter the liquid storage chamber.

[0010] The one-way valve has a blocking state and a conducting state. When the one-way valve is in the blocking state, the one-way valve blocks the air hole; when the one-way valve is in the conducting state, the one-way valve conducts the air hole to allow external air flow to enter the liquid storage chamber through the air hole; the one-way valve switches between the blocking state and the conducting state by moving relative to the air hole.

[0012] When the electronic atomization device is in operation, under the action of the air pressure difference, a partial area of ​​the valve body is separated from the first wall surface through elastic deformation, so that the one-way valve is switched to the conducting state.

[0013] In one embodiment, a side of the valve body facing away from the air hole is a curved surface, and from a middle region to a circumferential edge of the valve body, the curved surface curves toward a side close to the first wall surface; and / or,

The mounting wall has a positioning hole connected to the liquid storage chamber, and the positioning column is passed through the positioning hole to position and cooperate with the positioning hole so that the air hole is located within the coverage range of the valve body.

[0017] In one embodiment, the end of the positioning hole away from the liquid storage cavity is connected to the outside world, the positioning post is clamped in the positioning hole and blocks the positioning hole, and the end of the positioning post away from the fitting surface extends out of the positioning hole to form a protruding end.

[0023] An embodiment of the present application provides an electronic atomization device, wherein the atomizer module of the electronic atomization device includes a shell assembly, a nozzle and a one-way valve. The liquid storage chamber of the shell assembly is connected to the outside through an air hole. At least a part of the one-way valve is arranged in the liquid storage chamber, and is movably arranged at the connection between the liquid storage chamber and the air hole. The one-way valve has a blocking state and a conducting state. When the one-way valve is in the blocking state, the one-way valve blocks the air hole. When the one-way valve is in the conducting state, the one-way valve conducts the air hole to allow external air flow to enter the liquid storage chamber through the air hole. The one-way valve moves relative to the air hole to switch between the blocking state and the conducting state. On the one hand, by providing the air hole, it is possible to facilitate external air flow to enter the liquid storage chamber through the air hole to balance the air pressure inside and outside the liquid storage chamber, thereby facilitating liquid discharge.

At the same time, it can also make the atomization at the nozzle proceed smoothly, and can reduce the occurrence of undesirable phenomena such as intermittent mist discharge, no mist discharge, or atomization pulses caused by the negative pressure in the liquid storage chamber. Since the one-way valve is provided at the connection between the liquid storage chamber and the air hole, it only has the function of guiding the external air flow into the liquid storage chamber in the conducting state, thereby further reducing the risk of the atomized liquid in the liquid storage chamber flowing out of the liquid storage chamber through the air hole, making the sealing effect better.

[0030] An embodiment of the present application provides an electronic atomization device, which includes a host module and an atomizer module.

[0031] The host module includes a power supply assembly 30 and an air compressor 20 , and the power supply assembly 30 and the air compressor 20 are electrically connected.

[0032] See also Figure 2 、 Figure 3 and Figure 4 The atomizer module 10 includes a housing assembly 11 , a nozzle 12 and a one-way valve 13 .

[0033] The housing assembly 11 has a liquid storage chamber 11 a , a liquid channel 11 b , an air channel 11 d and an air hole 11 c . The liquid storage chamber 11 a is in communication with the outside through the air hole 11 c .

[0034] The nozzle 12 is arranged on the housing assembly 11, and the opposite ends of the liquid channel 11b are respectively connected to the liquid storage chamber 11a and the nozzle 12, the air compressor 20 is connected to one end of the air channel 11d, and the nozzle 12 is connected to the other end of the air channel 11d, so that the airflow from the air compressor 20 atomizes the atomized liquid from the liquid storage chamber 11a to generate an aerosol.

[0035] At least a portion of the one-way valve 13 is disposed in the liquid storage chamber 11 a and is movably disposed at the connection between the liquid storage chamber 11 a and the air hole 11 c.

[0036] The one-way valve 13 has a blocked state and a conductive state. When in the blocked state, the one-way valve 13 blocks the air hole 11c. When in the conductive state, the one-way valve 13 opens the air hole 11c, allowing external air to enter the liquid storage chamber 11a through the air hole 11c. The one-way valve 13 switches between the blocked and conductive states by moving relative to the air hole 11c.

[0037] Specifically, the electronic atomization device of the embodiment of the present application can be any type of atomization device, such as a scalp atomization drug delivery device, wherein the atomized liquid stored in the liquid storage chamber 11a is liquid medicine. In another example, the electronic atomization device is an electronic cigarette, wherein the atomized liquid stored in the liquid storage chamber 11a is tobacco oil.

[0038] Specifically, the atomizer module 10 is an atomizing component in an electronic atomizing device that can atomize atomizing liquid to generate aerosol.

[0039] The air compressor 20 in the embodiment of the present application refers to a device capable of compressing gas, such as an air pump.

[0040] The housing assembly 11 is the housing structure of the atomizer module 10 , and a liquid storage chamber 11 a , a liquid channel 11 b , an air channel 11 d and an air hole 11 c are formed therein.

[0041] The liquid storage chamber 11 a is a structure of the atomizer module 10 for storing atomized liquids such as liquid medicine and tobacco oil.

[0042] The liquid channel 11 b is a channel connecting the liquid storage chamber 11 a and the nozzle 12 , so as to allow the atomized liquid in the liquid storage chamber 11 a to move to the nozzle 12 under the action of air pressure and then be atomized.

[0043] The air hole 11c on the shell assembly 11 is used to connect the liquid storage chamber 11a with the outside, so that external gas can enter the liquid storage chamber 11a to balance the air pressure inside and outside the liquid storage chamber 11a, thereby facilitating the atomized liquid in the liquid storage chamber 11a to flow out.

[0044] The one-way valve 13 refers to a valve structure that allows external airflow to enter the liquid storage chamber 11 a through the air hole 11 c only in the conduction state.

[0045] Specifically, in the blocked state, the one-way valve 13 blocks the air hole 11 c, and the external air flow cannot enter the liquid storage chamber 11 a through the air hole 11 c, and the atomized liquid in the liquid storage chamber 11 a cannot flow out through the air hole 11 c.

[0046] In the on state, the one-way valve 13 opens the air hole 11 c, allowing external airflow to enter the liquid storage chamber 11 a through the air hole 11 c, while the atomized liquid in the liquid storage chamber 11 a cannot flow out through the air hole 11 c.

[0047] It should be noted that the specific manner in which the one-way valve 13 connects the air hole 11 c is not limited, and it only needs to ensure that the air hole 11 c is connected to the liquid storage chamber 11 a to allow external air to flow into the liquid storage chamber 11 a.

[0048] For example, the one-way valve 13 avoids the pore 11c as a whole so that the pore 11c is completely open. In another example, the one-way valve 13 avoids the pore 11c in a local area so that a part of the pore 11c is open.

[0049] The one-way valve 13 may have its entire area located within the liquid storage chamber 11 a , or may have a partial area located within the liquid storage chamber 11 a and a partial area located outside the liquid storage chamber 11 a .

[0050] Furthermore, the one-way valve 13 may be entirely disposed at the connection between the liquid storage chamber 11a and the air hole 11c and movable relative to the air hole 11c, or partially disposed at the connection between the liquid storage chamber 11a and the air hole 11c and movable relative to the air hole 11c.

[0051] The one-way valve 13 can switch between a blocking state and a conducting state by moving relative to the air hole 11c. The specific form of the one-way valve 13 moving relative to the air hole 11c is not limited, such as rotation, translation, elastic deformation, sliding, etc.

[0052] It should be noted that the specific structure of the one-way valve 13 is not limited. Depending on the structure, the method for implementing the movement of the one-way valve 13 relative to the air hole 11c may vary. For example, the one-way valve 13 may move relative to the air hole 11c due to the pressure difference between the liquid storage chamber 11a and the outside world. Switching the one-way valve 13 by the pressure difference can simplify the specific structure of the one-way valve 13 while better meeting the need to replenish the outside air into the liquid storage chamber 11a.

[0053] Of course, the one-way valve 13 may also adopt other structural types, such as a solenoid valve or other valve structures.

[0054] The material of the one-way valve 13 can also be set according to actual conditions. For example, the material of the one-way valve 13 is one of silicone, air rubber and fluorosilicone. Thus, the one-way valve 13 can have good elastic deformation ability and good sealing effect.

[0055] For another example, the hardness of the one-way valve 13 is greater than or equal to 40 degrees Shore A and less than or equal to 80 degrees Shore A, such as 40 degrees Shore A, 60 degrees Shore A, or 80 degrees Shore A. Thus, the one-way valve 13 can have a good hardness.

[0056] The sizes of the one-way valve 13 and the air hole 11c can also be set according to actual conditions.

[0057] For example, the diameter of the area where the one-way valve 13 is located within the liquid storage chamber 11a is greater than or equal to 6 mm and less than or equal to 9 mm, such as 6 mm, 8 mm, or 9 mm. These dimensions facilitate manufacturing while also matching the conventional liquid storage chamber 11a and air hole 11c.

[0058] For another example, the diameter of the air hole 11c is greater than or equal to 0.5 mm and less than or equal to 1 mm, such as 0.5 mm, 0.8 mm, or 1 mm. The above dimensions facilitate manufacturing and can also be compatible with the conventional liquid storage chamber 11a and the one-way valve 13.

[0059] In the electronic atomization device of the embodiment of the present application, the atomizer module 10 includes a shell assembly 11, a nozzle 12 and a one-way valve 13. The liquid storage chamber 11a of the shell assembly 11 is connected to the outside through the air hole 11c. At least part of the one-way valve 13 is arranged in the liquid storage chamber 11a, and is movably arranged at the connection between the liquid storage chamber 11a and the air hole 11c. The one-way valve 13 has a blocking state and a conducting state. When the one-way valve 13 is in the blocking state, the one-way valve 13 blocks the air hole 11c. When the one-way valve 13 is in the conducting state, the one-way valve 13 conducts the air hole 11c, so that the external air flow enters the liquid storage chamber 11a through the air hole 11c. The one-way valve 13 moves relative to the air hole 11c to switch between the blocking state and the conducting state. On the one hand, by providing the air hole 11c, it is possible to facilitate external airflow into the liquid storage chamber 11a through the air hole 11c, thereby balancing the air pressure inside and outside the liquid storage chamber 11a, thereby facilitating liquid discharge. On the other hand, a one-way valve 13 is provided at the connection between the liquid storage chamber 11a and the air hole 11c. When the one-way valve 13 is blocked, it can block the air hole 11c, thereby reducing the risk of the atomized liquid in the liquid storage chamber 11a flowing out of the liquid storage chamber 11a through the air hole 11c, thereby greatly improving the sealing effect within the liquid storage chamber 11a. Moreover, when the one-way valve 13 is in the conducting state, it can make the air hole 11c unobstructed, thereby facilitating external airflow into the liquid storage chamber 11a through the air hole 11c, thereby achieving the function of replenishing gas into the liquid storage chamber 11a. At the same time, it can also ensure smooth atomization at the nozzle 12, thereby reducing the occurrence of undesirable phenomena such as intermittent mist discharge, no mist discharge, or atomization pulses caused by the negative pressure in the liquid storage chamber 11a. Since a one-way valve 13 is provided at the connection point between the liquid storage chamber 11a and the air hole 11c, it only has the function of introducing the external airflow into the liquid storage chamber 11a in the conductive state, thereby further reducing the risk of the atomized liquid in the liquid storage chamber 11a flowing out of the liquid storage chamber 11a through the air hole 11c, thereby achieving a better sealing effect.

[0060] In one embodiment, please refer to Figure 3 The shell assembly 11 includes a mounting wall 111 having an air hole 11c, and the mounting wall 111 has a first wall surface 111a located in the liquid storage chamber 11a. The one-way valve 13 includes a valve body 131, and the valve body 131 is located in the liquid storage chamber 11a and is detachably attached to the first wall surface 111a. The air hole 11c is located within the coverage range of the valve body 131, so that the one-way valve 13 is in a blocked state.

[0061] When the electronic atomization device is in operation, under the action of the air pressure difference, a portion of the valve body 131 is separated from the first wall 111 a through elastic deformation, so that the one-way valve 13 is switched to the conducting state.

[0062] Specifically, the mounting wall 111 is a wall on the housing assembly 11 having the air hole 11c. The air hole 11c penetrates the mounting wall 111 to connect the liquid storage chamber 11a with the outside when the one-way valve 13 does not block the air hole 11c.

[0063] In practice, the valve body 131 is detachably attached to the wall area of ​​the housing assembly 11 at the connection between the liquid storage chamber 11a and the air hole 11c, thereby covering the air hole 11c. Therefore, the coverage area and cross-sectional dimensions of the valve body 131 are larger than the cross-sectional dimensions of the air hole 11c.

[0064] Therefore, when the electronic atomization device is working, the air compressor 20 supplies air to the nozzle 12 through the air channel 11d, and a negative pressure (such as a negative pressure of -1KPa to -4Kpa) is formed in the liquid channel 11b, so that the atomized liquid inside the liquid storage chamber 11a is liquid. As the atomized liquid is gradually consumed, the negative pressure in the liquid storage chamber 11a gradually decreases, and the air pressure difference between the liquid storage chamber 11a and the outside world also gradually increases. When the air pressure difference reaches the set air pressure range, the one-way valve 13 switches to the conduction state, and part of the valve body 131 undergoes elastic deformation and separates from the first wall 111a, so that the liquid storage chamber 11a is connected to the outside world through the air hole 11c, and then the external air flow can enter the liquid storage chamber 11a through the air hole 11c. As a result, the atomization at the nozzle 12 can be carried out smoothly, and the occurrence of undesirable phenomena such as intermittent mist, no mist or atomization pulses due to the negative pressure in the liquid storage chamber 11a can be reduced.

[0065] It should be noted that when the air pressure in the liquid storage chamber 11a is greater than or equal to the external air pressure, or when the pressure difference between the liquid storage chamber 11a and the external air pressure does not reach the set pressure range, the valve body 131 abuts against the first wall 111a, separating the air hole 11c from the liquid storage chamber 11a. Thus, a good sealing effect can be achieved.

[0066] The structural shape of the valve body 131 can be set according to actual conditions.

[0067] For example, see Figure 3 and Figure 4 The side of valve body 131 facing away from air hole 11c is a curved surface 131a. From the middle region to the peripheral edge of valve body 131, curved surface 131a curves toward the side closer to first wall 111a. In other words, the side surface of valve body 131 facing away from first wall 111a is a curved surface 131a, and it curves gradually from the middle to the periphery toward the side closer to first wall 111a. Thus, the formation of curved surface 131a further enhances the sealing effect.

[0068] Of course, in other embodiments, the side of the valve body 131 away from the air hole 11 c may also be an inclined surface.

[0069] For example, the cross-sectional dimensions of valve body 131 gradually decrease from its central region to its circumferential edge. In other words, valve body 131 employs a structure that gradually tapers from its central region toward its periphery. Consequently, under the influence of the pressure differential between the interior and exterior of liquid storage chamber 11a, the thinning of the circumferential edge of valve body 131 facilitates elastic deformation, allowing at least a portion of the circumferential edge to separate from first wall surface 111a, thereby maintaining the connection between air hole 11c and the surrounding air.

[0070] The air hole 11 c is located within the coverage of the valve body 131 , and its specific position relative to the valve body 131 can be set according to actual conditions.

[0071] For example, see Figure 4 The valve body 131 includes a transition section 1311 between the middle region and the circumferential edge. The air hole 11c is located within the coverage of the transition section 1311. The middle region of the valve body 131 is fixed to the mounting wall 111.

[0072] In other words, the air hole 11c is not located directly within the coverage of the central region, nor is it located directly within the coverage of the circumferential edge of the valve body 131. Instead, it is located within the coverage of the transition section 1311 between the two. This facilitates the fixing of the central region of the valve body 131 to the mounting wall 111, without interfering with the installation of the valve body 131. Furthermore, the placement of the air hole 11c at the circumferential edge of the valve body 131 prevents any impact on the sealing and waterproofing of the valve body 131.

[0073] In one embodiment, please refer to Figure 3 The valve body 131 has a fitting surface 131b that fits with the first wall surface 111a. The one-way valve 13 also includes a positioning column 132 arranged on the fitting surface 131b. The mounting wall 111 has a positioning hole connected to the liquid storage chamber 11a. The positioning column 132 is passed through the positioning hole to cooperate with the positioning hole so that the air hole 11c is located within the coverage range of the valve body 131.

[0074] Specifically, the positioning hole and the air hole 11 c are staggered with each other, thereby allowing the air hole 11 c and the positioning column 132 to avoid each other.

[0075] At the same time, the positioning post 132 is inserted into the positioning hole to cooperate with the positioning hole. On the one hand, it can facilitate the valve body 131 to cover the air hole 11c, so as to facilitate the installation of the one-way valve 13, and on the other hand, it can also enable the valve body 131 to be firmly installed on the installation wall 111 and not easily misplaced.

[0076] It should be noted that the positioning post 132 is inserted into the positioning hole. The positioning post 132 may be detachably disposed in the positioning hole or may be non-detachably disposed in the positioning hole.

[0077] For example, the positioning post 132 passes through the positioning hole and is engaged with the installation wall 111 .

[0078] For another example, the positioning post 132 is passed through the positioning hole and is threadedly connected to the mounting wall 111 .

[0079] The end of the positioning hole away from the liquid storage chamber 11a can be a closed end or an open end communicating with the outside.

[0080] For example, see Figure 3 and Figure 4 One end of the positioning hole away from the liquid storage chamber 11a is connected to the outside world, the positioning column 132 is stuck in the positioning hole and blocks the positioning hole, and one end of the positioning column 132 away from the fitting surface 131b extends out of the positioning hole to form a protruding end 1321.

[0081] Specifically, the positioning post 132 is inserted into the positioning hole to engage with the mounting wall 111 and seal the positioning hole to prevent the atomized liquid in the liquid storage chamber 11 a from flowing out through the positioning hole.

[0082] By extending one end of the positioning post 132 away from the fitting surface 131 b out of the positioning hole, the positioning post 132 can be better passed through the positioning hole, so that the one-way valve 13 can be installed on the installation wall 111.

[0083] In one embodiment, please refer to Figure 3 and Figure 4 The mounting wall 111 has a second wall 111b away from the first wall 111a, and a partial area of ​​the protruding end 1321 protrudes to form an inverted position 1322. The outer dimensions of the inverted position 1322 are larger than the opening size of the positioning hole, and the inverted position 1322 abuts against the second wall 111b.

[0084] Specifically, the second wall surface 111 b is a side of the installation wall 111 opposite to the first wall surface 111 a , that is, the first wall surface 111 a and the second wall surface 111 b are wall surfaces on opposite sides of the installation wall 111 .

[0085] A protruding undercut 1322 is formed on one end of the positioning post 132 away from the fitting surface 131b. In the area where the positioning hole is located at the second wall 111b, since the size of the undercut 1322 is larger than the opening size of the positioning hole, the undercut 1322 abuts against the second wall 111b, making it difficult for the undercut 1322 to pass through the positioning hole under the action of the air pressure difference. Therefore, when the electronic atomization device is working, under the action of the air pressure difference, a part of the valve body 131 is separated from the first wall 111a through elastic deformation, so that the air flow is replenished to the liquid storage chamber 11a through the air hole 11c. Since the undercut 1322 and the second wall 111b abut each other, it is possible to limit the valve body 131. In this way, while a part of the valve body 131 is separated from the first wall 111a through elastic deformation, it will not completely detach from the first wall 111a due to the air pressure difference. At the same time, when the electronic atomization device stops working, it can also avoid the situation where the one-way valve 13 cannot be switched back to the blocked state.

[0086] In one embodiment, the undercut portion 1322 is made of an elastically deformable material. During installation of the one-way valve 13, the undercut portion 1322 can be elastically deformed to pass through the positioning hole from one side of the liquid storage chamber 11a to abut against the second wall 111b. This facilitates better installation of the one-way valve 13.

[0087] In one specific embodiment, during the installation of the one-way valve 13, the protruding end 1321 is inserted into the positioning hole from one side of the liquid storage chamber 11a. When the undercut portion 1322 reaches the connection between the positioning hole and the liquid storage chamber 11a, the protruding end 1321 passes through the positioning hole to the outside world. The protruding end 1321 is pulled by hand or with a clamp, causing the undercut portion 1322 to elastically deform and pass through the positioning hole until it reaches the connection between the positioning hole and the outside world. At this point, the undercut portion 1322 returns to its original state, thereby abutting against the second wall 111b. This prevents the one-way valve 13 from falling out, and the overall assembly is simple, efficient, and low-cost.

[0088] It should be noted that, in some embodiments, the portion of the protruding end 1321 below the undercut portion 1322 may be cut off to reduce interference of the protruding end 1321 with other structures.

[0089] In one embodiment, the housing assembly 11 includes a top cover, an atomizer cartridge, and a dustproof sealing cover with a mounting cavity. One end of the mounting cavity is open to form an installation entrance. The atomizer cartridge includes an atomizer cartridge body and an atomizer cartridge adapter. The atomizer cartridge body and the atomizer cartridge adapter enclose a liquid storage cavity 11a. An air hole 11c is located on the atomizer cartridge adapter. The atomizer cartridge is located within the mounting cavity, and the atomizer cartridge adapter is located on one side of the installation entrance. The top cover is located at the installation entrance and has a port connecting the air hole 11c to the outside world.

[0090] The atomizer module 10 may further include small comb teeth, which are located in the mounting cavity and on a side of the atomizer cartridge body that is away from the atomizer cartridge adapter.
