Description

Technical Field

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

[0002] Electronic atomization device, also known as electronic cigarette, is a device that heats the atomization medium and atomizes it to generate aerosol for users to inhale to simulate the feeling of smoking. As a substitute for cigarettes, it is deeply loved by smokers. The traditional electronic atomization device consists of an atomizer and a power supply unit, wherein the atomizer has an oil storage chamber and an atomization core inside, and the oil is stored in the oil storage chamber. The power supply unit supplies power to the atomization core, heats the oil in the oil storage chamber and atomizes it to generate aerosol for users to inhale.

[0003] In order to increase the suction volume of electronic atomizer devices, some large-capacity pre-oiled electronic atomizer devices and open-type oil-filling (i.e., users open the oil filling plug to fill oil by themselves) electronic atomizer devices are currently on the market. Although the above-mentioned types of electronic atomizer devices have the advantage of large oil storage capacity, since the oil storage chamber mostly adopts a fixed sealing structure, when the user opens the oil filling plug to fill oil or performs high-temperature testing, it is easy to cause oil leakage due to the imbalance of internal and external pressures of the oil storage chamber; for example, when the external air pressure or temperature changes, the internal pressure of the oil storage chamber may be higher than the external air pressure, causing the oil in the oil storage chamber to leak from the center hole of the atomizer tube to the outside of the atomizer under the action of the air pressure difference, affecting the user's experience. Summary of the invention

[0004] Based on this, it is necessary to provide an atomizer and an electronic atomizer device including the atomizer that can solve the above problems, in view of the fact that the existing electronic atomization device is prone to oil leakage due to the imbalance of internal and external pressures of the oil storage chamber when the user opens the oil filling plug to fill oil or conducts high-temperature testing.

[0015] In one of the embodiments, the pressure relief assembly further includes a pressure relief pipe, and the pressure relief pipe is inserted into the first pressure relief hole.

[0041] An embodiment of the present application provides an electronic atomization device, which is used to heat an atomization medium stored inside the electronic atomization device to form an aerosol for inhalation by a user.

[0042] The following takes the electronic atomization device as an electronic cigarette as an example, and the atomization medium as smoke oil as an example to illustrate the structure of the electronic atomization device in the present application. This embodiment is only used as an example and does not limit the technical scope of the present application. It can be understood that in other embodiments, the electronic atomization device of the present application is not limited to an electronic cigarette, but can also be any other electronic atomization device that can atomize the atomization medium into an aerosol, which is not limited here.

[0043] Referring to FIGS. 1 to 4 , FIG. 1 shows a schematic diagram of the appearance of an electronic atomization device 10 in an embodiment of the present application, FIG. 2 shows a top view of the electronic atomization device 10 , and FIG. 3 shows a cross-sectional view of the internal structure of the electronic atomization device 10 . Figure 4An exploded schematic diagram of the electronic atomization device 10 is shown. The electronic atomization device 10 provided in one embodiment of the present application includes an atomizer 100 and a power supply unit 200. The power supply unit 200 and the atomizer 100 are connected to each other. The atomizer 100 is provided with a first air inlet 101 and an air outlet 102 that are connected to each other. The power supply unit 200 is provided with a second air inlet 201 that is connected to the first air inlet 101. The power supply unit 200 is used to supply power to the atomizer 100. The atomizer 100 is used to heat the tobacco oil stored in itself under the action of the electric energy provided by the power supply unit 200, so that the tobacco oil can be atomized to generate an aerosol; when the user inhales, the outside air enters the power supply unit 200 from the second air inlet 201, and then enters the atomizer 100 through the first air inlet 101, and is mixed with the aerosol and inhaled by the user from the air outlet 102.

[0044] In one embodiment, Figure 3 and Figure 4 As shown, the atomizer 100 includes a housing assembly 110 and an atomizer assembly 120. The housing assembly 110 has an oil storage chamber 110a for containing tobacco oil. The first air inlet 101 and the air outlet 102 are provided at opposite ends of the housing assembly 110. The atomizer assembly 120 is disposed in the housing assembly 110. Figure 5 As shown, the atomization assembly 120 includes a second atomization tube 121 and an atomization core 122 arranged in the second atomization tube 121, an atomization chamber 120a is formed in the atomization core 122, and the atomization chamber 120a is connected with the first air inlet 101 and the air outlet 102 through the second atomization tube 121; the second atomization tube 121 is provided with an oil inlet hole 120b at a position corresponding to the atomization core 122, and the oil inlet hole 120b connects the oil storage chamber 110a and the atomization core 122; when the electronic atomization device 10 is working, the tobacco oil in the oil storage chamber 110a can enter the atomization core 122 through the oil inlet hole 120b, so that it can be heated by the atomization core 122 to form aerosol, and flow out from the air outlet 102 through the second atomization tube 121 for the user to inhale.

[0045] However, for the above-mentioned embodiment, as described in the background technology, when the user opens the oil filling plug to fill the oil storage chamber 110a or the temperature and air pressure outside the device change, the air pressure in the oil storage chamber 110a is prone to change, resulting in an imbalance in the air pressure between the oil storage chamber 110a and the atomization chamber 120a. During the use of the electronic atomization device 10, the smoke oil in the oil storage chamber 110a will continue to be transferred to the atomization core 122 under the action of the continuous air pressure difference. When the transferred smoke oil exceeds the maximum oil locking capacity of the atomization core 122, the excess smoke oil will leak from the atomization chamber 120a to the outside of the atomizer 100, affecting the user's experience.

[0046] Therefore, as an improvement to the above embodiment, Figure 3 and Figure 4 As shown, the atomizer 100 further includes a pressure relief assembly 130, which is disposed in the oil storage chamber 110a and sleeved on the atomizing assembly 120, and the pressure relief assembly 130 has a first end close to the top of the oil storage chamber 110a and a second end close to the bottom of the oil storage chamber 110a, as shown in FIG. Figure 6 As shown, the first end of the pressure relief assembly 130 is provided with a first pressure relief hole 130a communicating with the oil storage chamber 110a and the oil inlet hole 120b, and the second end is provided with a second pressure relief hole 130b communicating with the oil storage chamber 110a and the oil inlet hole 120b.

[0047] In this way, by setting up the pressure relief component 130, when the pressure difference between the oil storage chamber 110a and the atomization chamber 120a is unbalanced, the air flow can flow between the oil storage chamber 110a and the atomization chamber 120a through the first pressure relief hole 130a or the second pressure relief hole 130b, thereby achieving the pressure difference balance between the oil storage chamber 110a and the atomization chamber 120a, and solving the problem of oil leakage caused by the unbalanced internal and external pressures of the oil storage chamber 110a.

[0048] Please continue reading Figure 3 and Figure 4 In a specific embodiment, the housing assembly 110 includes a housing 111 and a base 112. One end of the housing 111 is open, and the base 112 closes the opening. The end of the housing 111 away from the base 112 has a connecting column 1111 extending toward the inside of the housing 111. The first air inlet 101 passes through the base 112, and the air outlet 102 passes through the connecting column 1111. The base 112 includes a bottom cover 1121 and a second sealing member 1122 disposed on the bottom cover 1121. The pressure relief assembly 1 One end of the pressure relief assembly 130 is connected to the connecting column 1111, and the other end of the pressure relief assembly 130 and the end of the atomizer assembly 120 away from the air outlet 102 are connected to the second sealing member 1122, so that the inner wall of the shell 111, the side of the second sealing member 1122 away from the bottom cover 1121 and the outer wall of the pressure relief assembly 130 are jointly constructed to form the oil storage chamber 110a, and the second sealing member 1122 can seal the smoke oil in the oil storage chamber 110a, so as to prevent the smoke oil from leaking from the bottom of the shell 111.

[0049] In the structure of the pressure relief assembly 130, as shown in FIG. Figure 6 and Figure 7As shown, the pressure relief assembly 130 includes a first atomization tube 131 and a first breathable oil-conducting cotton 132 coaxially sleeved on the atomization assembly 120, the inner wall of the first atomization tube 131 and the outer wall of the atomization assembly 120 form a mounting groove 130c, the first oil-conducting cotton 132 is filled in the mounting groove 130c, at least a portion of the first pressure relief hole 130a is opened in the first oil-conducting cotton 132, the second pressure relief hole 130b is opened on the tube wall of the first atomization tube 131 and connected to the mounting groove 130c, and the first oil-conducting cotton 132 covers the outer opening of the oil inlet hole 120b and the inner opening of the second pressure relief hole 130b.

[0050] It should be noted that the inner side and outer side mentioned above are relative to the inner side and outer side of the first atomizing tube 131. The inner side is defined as the inner side of the first atomizing tube 131, and the outer side is defined as the outer side of the first atomizing tube 131. Figure 8 As shown, when the electronic atomization device 10 is upright (i.e., when the air outlet 102 faces upward), the smoke oil 30 can enter the first oil-conducting cotton 132 from the second pressure relief hole 130b. In addition to being breathable, the first oil-conducting cotton 132 can also lock and guide the oil. Therefore, the smoke oil 30 can be directed upward to a position close to the oil inlet hole 120b, so that the smoke oil 30 can enter the atomization assembly 120 through the oil inlet hole 120b; at the same time, when there is an imbalance in the internal and external pressure difference between the atomization chamber 120a and the oil storage chamber 110a, the air in the atomization chamber 120a and the oil storage chamber 110a can circulate with each other through the first pressure relief hole 130a, so that the internal and external pressure difference between the atomization chamber 120a and the oil storage chamber 110a reaches a balanced state. Fig. 9 As shown, when the electronic atomization device 10 is inverted (i.e., the air outlet 102 is facing downward) and when there is an unbalanced internal and external pressure difference between the atomization chamber 120a and the oil storage chamber 110a, the air in the atomization chamber 120a and the oil storage chamber 110a can circulate with each other through the second pressure relief hole 130b, thereby also making the internal and external pressure difference between the atomization chamber 120a and the oil storage chamber 110a reach a balanced state.

[0051] For example, when the air pressure in the oil storage chamber 110a is greater than the air pressure in the atomization chamber 120a, air can enter the first oil-conducting cotton 132 from the first pressure relief hole 130a or the second pressure relief hole 130b, then flow from the micropores of the first oil-conducting cotton 132 to the oil inlet hole 120b, and then enter the atomization chamber 120a from the oil inlet hole 120b; conversely, when the air pressure in the atomization chamber 120a is greater than the air pressure in the oil storage chamber 110a, air can enter the first oil-conducting cotton 132 from the atomization chamber 120a through the oil inlet hole 120b, then flow from the micropores of the first oil-conducting cotton 132 to the first pressure relief hole 130a or the second pressure relief hole 130b, and then enter the oil storage chamber 110a from the first pressure relief hole 130a or the second pressure relief hole 130b, so as to achieve the purpose of achieving air pressure balance between the oil storage chamber 110a and the atomization chamber 120a.

[0052] Furthermore, if Figure 6 and Figure 7 As shown, the pressure relief assembly 130 also includes a first seal 133, one end of the first seal 133 along its own axial direction is connected to the housing assembly 110, and the other end is connected to one end of the first atomizing tube 131 close to the air outlet 102, a part of the first pressure relief hole 130a passes through the first seal 133, and the other part is opened in the first oil-conducting cotton 132. Specifically, one end of the first seal 133 is sleeved on the connecting column 1111 of the housing 111 in an interference fit, and the other end is inserted in the first atomizing tube 131 in an interference fit and sleeved on the atomizing assembly 120, so that the aerosol in the atomizing chamber 120a can be prevented from leaking from between the atomizing assembly 120 and the connecting column 1111, thereby ensuring that all the aerosol after atomization can be inhaled by the user from the air outlet 102, thereby ensuring a good suction taste.

[0053] exist Figure 6 and Figure 7 In the embodiment shown in , there are two first pressure relief holes 130a, and the two first pressure relief holes 130a are arranged on both sides of the central axis along the radial direction defined by the central axis of the pressure relief component 130 (i.e., the central axis of the atomization component 120). Of course, it can be understood that the number of first pressure relief holes 130a is not limited to two, and can also be multiple, all first pressure relief holes 130a are arranged in pairs, and each pair of first pressure relief holes 130a is arranged on both sides of the central axis along the radial direction defined by the above-mentioned central axis. By providing more than two first pressure relief holes 130a, the air can have more flow paths, so that the air pressure balance can be quickly achieved in the atomization chamber 120a and the oil storage chamber 110a.

[0054] Preferably, if Figure 7 As shown, a pressure relief pipe 134 is inserted into the first pressure relief hole 130a. This is because the material of the first oil-conducting cotton 132 is relatively soft. In order to avoid the hole walls of the first pressure relief hole 130a sticking to each other, the pressure relief pipe 134 can expand the first pressure relief hole 130a, thereby avoiding blockage of the first pressure relief hole 130a.

[0055] Furthermore, if Figure 5As shown, the pressure relief assembly 130 also includes an air relief seat 135, which is sleeved on one end of the first atomization tube 131 close to the first air inlet 101 and covers the second pressure relief hole 130b; in the specific structure of the air relief seat 135, the outer diameter of the air relief seat 135 along its own axial direction is a structure with one end larger and the other end smaller, that is, from the first air inlet 101 to the direction of the air outlet 102, the outer diameter of the air relief seat 135 gradually decreases, so that the inner wall of the air relief seat 135 and the outer wall of the first atomization tube 131 are structured to form an air relief cavity 1351 connected to the second pressure relief hole 130b, and a third pressure relief hole 1352 is opened on the side of the air relief seat 135, and the oil storage cavity 110a is connected to the air relief cavity 1351 through the third pressure relief hole 1352.

[0056] In this way, when the electronic atomization device 10 is inverted and the air pressure in the atomization chamber 120a is higher than the air pressure in the oil storage chamber 110a, the air can pass through the second pressure relief hole 130b, the air relief hole 1351 and the third pressure relief hole 1352 from the atomization chamber 120a in sequence to reach the oil storage chamber 110a to achieve air pressure balance; or when the air pressure in the oil storage chamber 110a is higher than the air pressure in the atomization chamber 120a, the air can pass through the third pressure relief hole 1352, the air relief hole 1351 and the second pressure relief hole 130b from the oil storage chamber 110a in sequence to reach the oil storage chamber 110a. and precisely because the air relief seat 135 is designed as the above structure, when the electronic atomization device 10 is placed in the horizontal direction (i.e., the opening of the air outlet 102 is facing in the horizontal direction) and the air pressure in the oil storage chamber 110a is higher than the air pressure in the atomization chamber 120a, the opening of the third pressure relief hole 1352 can be higher than the liquid level of the smoke oil 30, and the air in the atomization chamber 120a and the oil storage chamber 110a can still circulate with each other, thereby achieving air pressure balance between the atomization chamber 120a and the oil storage chamber 110a.

[0057] At the same time, the air leakage chamber 1351 is formed by setting the air leakage seat 135, so that when the electronic atomization device 10 is placed upright, the smoke oil 30 in the oil storage chamber 110a can continuously flow into the air leakage chamber 1351 from the third pressure relief hole 1352. Even if the smoke oil 30 in the oil storage chamber 110a is used up, there is still a small amount of smoke oil 30 in the air leakage chamber 1351. Therefore, when the user continues to inhale, the small amount of smoke oil 30 in the air leakage chamber 1351 can continue to be supplied to the atomization component 120 for a period of time for heating and atomization, thereby avoiding the phenomenon of dry burning of the atomization component 120 caused by the user continuing to inhale after the smoke oil 30 in the oil storage chamber 110a is exhausted.

[0058] See also Fig.10 As a further improvement to the structure of the air release seat 135, the air release seat 135 is provided with a plurality of protrusions 1353 spaced around the central axis of the air release seat 135 on the outer peripheral side surface of the end with a larger outer diameter, and each protrusion 1353 is provided with a third pressure relief hole 1352. Fig.11and Fig.12 As shown, by providing the protrusion 1353, it can be ensured that when there is still a lot of smoke oil 30 in the oil storage chamber 110a and the electronic atomization device 10 is placed in the horizontal direction, the opening height of the third pressure relief hole 1352 is still higher than the liquid level of the smoke oil 30, so that the smoke oil 30 will not cover the opening of the third pressure relief hole 1352, thereby still ensuring that the atomization chamber 120a and the oil storage chamber 110a can achieve air pressure balance when the electronic atomization device 10 is placed in the horizontal direction. Of course, the number of the third pressure relief hole 1352 and the protrusion 1353 is not limited, it can be one or any number, and is not limited here.

[0059] Please continue reading Figure 5 In one embodiment, the first oil-conducting cotton 132 of the pressure relief assembly 130 is attached to the tube wall of the second atomization tube 121 and covers the outer opening of the oil inlet hole 120b, and the atomization core 122 is arranged in the atomization chamber 120a. In one embodiment, the atomization core 122 includes a breathable second oil-conducting cotton and a heating element connected to the second oil-conducting cotton. The second oil-conducting cotton is cylindrical, and its outer peripheral surface is attached to the cavity wall of the atomization chamber 120a and covers the inner opening of the oil inlet hole 120b. The second oil-conducting cotton is made of the same material as the first oil-conducting cotton 132, and both have the functions of air permeability, oil locking and oil guiding. Therefore, the gas can pass through the first oil-conducting cotton 132 and the second oil-conducting cotton, so that the first pressure relief hole 130a and the second pressure relief hole 130b are connected to the oil inlet hole 120b through the first oil-conducting cotton 132, and the oil inlet hole 120b is connected to the air outlet 102 through the second oil-conducting cotton.

[0060] It should be noted again that the inside and outside here are relative to the second atomization tube 121, the inside of the second atomization tube 121 is defined as the inside, and the outside of the second atomization tube 121 is defined as the outside.

[0061] Please continue reading Figure 3 ,exist Figure 3 In the embodiment shown in , the power supply unit 200 includes a housing 210 and an electronic component 220, the atomizing chamber 120a is connected to the housing 210, and the electronic component 220 is disposed in the housing 210 and electrically connected to the heating element of the atomizing core 122; the electronic component 220 includes a battery, a circuit board, an airflow sensor, etc., and its specific structure can refer to the prior art and will not be repeated here.

[0062] In order to prevent the condensate generated in the atomizing chamber 120a after the aerosol is cooled from leaking into the power supply unit 200 and damaging the electronic component 220, in a preferred embodiment, a partition 211 is provided in the housing 210, and the partition 211 divides the inner cavity of the housing 210 into a first cavity and a second cavity, the second air inlet 201 is opened on the bottom wall of the first cavity, the first cavity is provided with oil-absorbing cotton 230 and is arranged in a vertical direction aligned with the first air inlet 101, the electronic component 220 is arranged in the second cavity and is arranged in a vertical direction offset with the atomizer 100, and the oil-absorbing cotton 230 is provided with a vent 231 connecting the first air inlet 101 and the second air inlet 201. In this way, the condensate generated in the atomizing chamber 120a drops from the first air inlet 101 and drips into the oil-absorbing cotton 230, thereby preventing the condensate from leaking from the second air inlet 201 or leaking into the electronic component 220.

[0063] In addition, if Fig.13 As shown, at least two second air inlets 201 are provided, and an air regulating member 240 is movably provided at the bottom of the shell 210. The air regulating member 240 can move relative to the shell 210 to cover at least one second air inlet 201 or be staggered with all the second air inlets 201, so that different numbers of second air inlets 201 can be opened, thereby adjusting the amount of air intake, so that the user can have different smoking tastes when inhaling; and the air regulating member 240 can also cover all the second air inlets 201, so that all the second air inlets 201 can be blocked, so that the electronic component 220 cannot be started to work to power the atomization core 122 during inhalation, thereby preventing children from accidentally starting the electronic atomization component 120 when playing.

[0064] To sum up, the electronic atomization device 10 provided in the present application can allow the air between the oil storage chamber 110a and the atomization chamber 120a to circulate between each other no matter how it is placed, so that the pressure difference balance between the oil storage chamber 110a and the atomization chamber 120a can always be ensured. Therefore, under the premise of simple structure and low production cost, the oil leakage problem of the existing pre-oil-filled electronic atomization device or the open non-oil-filled electronic atomization device due to the imbalance of internal and external pressure of the oil storage chamber is solved.
