DETAILED DESCRIPTION

[0036] The application will be further described below in conjunction with the drawings and embodiments. It is particularly pointed out that the following embodiments are only used to illustrate the application, but do not limit the scope of the application.

Therefore, the features limited by "first", "second", "third" can explicitly or implicitly include at least one of the features. In the description of the application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise specifically limited. All directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the application are only used to explain the relative positional relationship, movement condition, etc. between the components in a certain posture (as shown in the drawings), and if the certain posture changes, the directional indications also change accordingly.

For example, a process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, but can optionally include steps or units not listed, or can optionally include other steps or components inherent to the process, method, product or device.

[0038] Reference to“an embodiment” herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase“in an embodiment” in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive of one another. It is expressly understood that any of the embodiments described herein can be incorporated into any other embodiment.

[0039] Embodiments of the application provide an atomization device 10, as shown in Figure 1 and Figure 2 The atomization device 10 includes a first liquid storage bin 101, a second liquid storage bin 102, an atomization core 110, and a valve assembly 200. The first liquid storage bin 101 is used to store an atomization medium, the second liquid storage bin 102 is used to store an atomization medium to be atomized, the atomization core 110 is used to heat the atomization medium in the second liquid storage bin 102 to form an aerosol; the valve assembly 200 is in fluid communication with the first liquid storage bin 101 and the second liquid storage bin 102, respectively, and the valve assembly 200 is used to control the communication state between the first liquid storage bin 101 and the second liquid storage bin 102.

[0040] The existing large-capacity atomization device 10 has a large volume of the liquid storage bin, and the liquid pressure generated by the atomization medium inside the liquid storage bin is high. In a negative pressure and high and low temperature change environment, the increased pressure in the liquid storage bin can easily cause the atomization medium to leak.

[0041] The application can separate the oil storage bin into the first liquid storage bin 101 and the second liquid storage bin 102 by setting the valve assembly 200, reduce the pressure inside the single liquid storage bin, and make the atomization medium in the first liquid storage bin 101 controllably flow to the second liquid storage bin 102 and be heated and atomized, thereby avoiding the atomization medium leakage problem caused by liquid pressure and improving the stability and reliability of the atomization device 10.

[0042] In some embodiments, the atomization device 10 can also be provided with multiple liquid storage bins, and the number of liquid storage bins can be 2, 4, 5, etc. The valve assembly 200 can also be multiple and control the communication state of adjacent liquid storage bins.

[0043] In some embodiments, the capacity of the second liquid storage bin 102 is less than the capacity of the first liquid storage bin 101, and the capacity of the second liquid storage bin 102 can be 1ml-2ml. Specifically, the capacity of the second liquid storage bin 102 can be 1ml, 1.24ml, 1.5ml, 2ml, and any value between the above capacities.

[0044] In some embodiments, the valve assembly 200 is normally in the closed state, disconnecting the first liquid storage chamber 101 and the second liquid storage chamber 102. The atomizing matrix in the second liquid storage chamber 102 is used to be heated by the atomizing core 110 to form an aerosol. Because the amount of atomizing matrix stored in the second liquid storage chamber 102 is small, the resulting liquid pressure is low, and even under negative pressure and high / low temperature changes within the second liquid storage chamber 102, leakage of the atomizing matrix will not occur. The first liquid storage chamber 101 does not atomize the atomizing matrix, and there are no negative pressure or high / low temperature changes; its internal environment is stable, so even if a large amount of atomizing matrix is ​​stored, leakage will not occur. When the atomizing matrix in the second liquid storage chamber 102 is consumed or reduced to a certain level, the valve assembly 200 can be switched to the open state, connecting the first liquid storage chamber 101 and the second liquid storage chamber 102. The atomizing matrix in the first liquid storage chamber 101 can flow to the second liquid storage chamber 102 through the valve assembly 200 and be heated and atomized to form an aerosol.

[0045] In some embodiments, the atomizing core 110 is disposed inside the second liquid storage chamber 102. In other embodiments, the atomizing core 110 may also be disposed outside the second liquid storage chamber 102, for example, the atomizing core 110 may be attached to the bottom of the second liquid storage chamber 102.

[0046] In some embodiments, the atomizing device 10 further includes a battery cell 900, which is electrically connected to the atomizing core 110 to supply power to the atomizing core 110. In some other embodiments, the atomizing device 10 may not include the battery cell 900, and the atomizing device 10 supplies power to the atomizing core 110 through an external battery cell 900.

[0047] In some embodiments, such as Figure 3 As shown, the valve assembly 200 includes a control valve 230, a first connecting pipe 210 and a second connecting pipe 220. The first connecting pipe 210 is connected to the first liquid storage tank 101, and the second connecting pipe 220 is connected to the second liquid storage tank 102. The control valve 230 is used to control the connection state between the first connecting pipe 210 and the second connecting pipe 220.

[0048] In some embodiments, the valve assembly 200 has a U-shaped structure, the control valve 230 is located at the bend of the U-shaped structure, and one end of the first connecting pipe 210 and one end of the second connecting pipe 220 are connected to the control valve 230.

[0049] In some embodiments, such as Figure 7As shown, the first communicating pipe 210 is provided with a first opening 2101 at one end close to the first liquid storage bin 101, and the second communicating pipe 220 is provided with a second opening 2201 at one end close to the second liquid storage bin 102. The height of the first opening 2101 is higher than the height of the second opening 2201. According to the principle of communicating vessels, when two or more containers are connected through the bottom opening channel, the liquid level of each container in the static fluid is equal. Due to the height of the first opening 2101 being higher than the height of the second opening 2201, when the first communicating pipe 210 and the second communicating pipe 220 are connected, the atomized substrate at the first opening 2101 will spontaneously flow to the second opening 2201 under the influence of liquid pressure, that is, the atomized substrate in the first liquid storage bin 101 will spontaneously flow to the second liquid storage bin 102.

[0050] Specifically, along the height direction H of the valve assembly 200, the height of the first opening 2101 is higher than the height of the second opening 2201, and the distance from the first opening 2101 to the control valve 230 is farther than the distance from the second opening 2201 to the control valve 230.

[0051] In some embodiments, the control valve 230 is an electromagnetic valve, and the end of the first communicating pipe 210 away from the first liquid storage bin 101 and the end of the second communicating pipe 220 away from the second liquid storage bin 102 are connected to the control valve 230. The electromagnetic valve is an automatic device that controls the flow of fluid (such as gas or liquid) through electromagnetic force, widely used in industrial control, medical devices, smart home, etc. The core principle is that the magnetic field generated by the electromagnet acts on the valve core, thereby changing the opening and closing state of the valve.

[0052] Specifically, the control valve 230 can be a direct-acting electromagnetic valve. The principle of the direct-acting electromagnetic valve is that when energized, the electromagnetic coil generates electromagnetic force, directly lifting the valve core from the valve seat to open the valve; when de-energized, the electromagnetic force disappears, and the spring presses the valve core back to the valve seat to close the valve. In some other embodiments, the control valve 230 can also be a step-by-step direct-acting electromagnetic valve, a pilot-operated electromagnetic valve, or other similar electromagnetic valves.

[0053] In some other embodiments, the control valve 230 can also be a one-way valve or other types of valves. The one-way valve, also known as check valve or non-return valve, is used in hydraulic systems to prevent oil from flowing in the opposite direction, or in pneumatic systems to prevent compressed air from flowing in the opposite direction. By setting the one-way valve, the atomized substrate can only flow from the first liquid storage bin 101 to the second liquid storage bin 102, and cannot flow in the opposite direction. In this case, the height of the first opening 2101 can be lower than or equal to the height of the second opening 2201.

[0054] In some embodiments, as shown in FIG. 2B, the first communicating pipe 210 and the second communicating pipe 220 are connected to the control valve 230 through a pipe connector 240. Figure 3As shown, the control valve 230 is arranged at one end of the second liquid storage chamber 102 away from the first liquid storage chamber 101, and the first communication pipe 210 penetrates the second liquid storage chamber 102. Specifically, the first communication pipe 210 is at least partially located in the second liquid storage chamber 102, and the first communication pipe 210 does not directly communicate with the second liquid storage chamber 102, but communicates with the first liquid storage chamber 101 through the second liquid storage chamber 102. The control valve 230, the second liquid storage chamber 102, and the first liquid storage chamber 101 are stacked in sequence, and the design that the first communication pipe 210 penetrates the second liquid storage chamber 102 is conducive to reducing the space occupied by the valve assembly 200, and thus reducing the overall volume of the atomization device 10.

[0055] In some embodiments, as shown in Figure 5 As shown, the atomization device 10 further comprises a housing 300 and a bracket 400, and a first sealing member 500 is sealingly connected between the housing 300 and the bracket 400. The first liquid storage chamber 101 is formed between the housing 300 and the first sealing member 500, and the second liquid storage chamber 102 is formed between the bracket 400 and the first sealing member 500.

[0056] In some embodiments, the first liquid storage chamber 101 and the second liquid storage chamber 102 are respectively arranged on opposite sides of the first sealing member 500. The first sealing member 500 can be in interference fit with the housing 300 and the bracket 400. The material of the first sealing member 500 is a flexible silicone or rubber material.

[0057] In some embodiments, as shown in Figure 6 As shown, the first sealing member 500 is provided with a support member 510 on the side close to the second liquid storage chamber 102. The support member 510 abuts between the first sealing member 500 and the bracket 400 to support the first sealing member 500. Specifically, the support member 510 can be in the form of a plate. The material of the support member 510 can be a hard metal or plastic.

[0058] In some embodiments, as shown in Figure 3 and Figure 8 As shown, the bracket 400 comprises a partition 410. The partition 410 is provided with a receiving cavity 401 on the side away from the second liquid storage chamber 102. The control valve 230 is arranged in the receiving cavity 401. The partition 410 is provided with a first through hole 4101 and a second through hole 4102 which communicate with the second liquid storage chamber 102. The first communication pipe 210 is inserted into the first through hole 4101, and the second communication pipe 220 is inserted into the second through hole 4102. The atomization device 10 further comprises a second sealing member 600. The second sealing member 600 is sealingly connected between the first communication pipe 210 and the partition 410, and the second sealing member 600 is sealingly connected between the second communication pipe 220 and the partition 410.

[0059] In some embodiments, there are multiple second seals 600. Specifically, there are two second seals 600, which are respectively sealed between the first connecting pipe 210 and the partition 410, and sealed between the second connecting pipe 220 and the partition 410.

[0060] In some embodiments, such as Figure 10 As shown, the second sealing element 600 is an integral structure. The second sealing element 600 has a fifth through hole 601 and a sixth through hole 602. The first connecting pipe 210 is inserted into the fifth through hole 601, and the second connecting pipe 220 is inserted into the sixth through hole 602. The sidewall of the fifth through hole 601 abuts against the first connecting pipe 210 and the partition 410, and the sidewall of the sixth through hole 602 abuts against the second connecting pipe 220 and the partition 410.

[0061] In some embodiments, the first through hole 4101 and the second through hole 4102 are connected, that is, the first through hole 4101 and the second through hole 4102 are not separated, so that the second seal 600 of the integral structure can be inserted into the first through hole 4101 and the second through hole 4102 at the same time.

[0062] In some embodiments, the second seal 600 is made of elastic silicone or rubber.

[0063] In some embodiments, such as Figure 6 As shown, a liquid guide pipe 120 is provided in the second liquid storage tank 102, and the liquid guide pipe 120 is connected to the second liquid storage tank 102. The second sealing member 600 is provided with a connecting pipe 610, and a sixth through hole 602 is formed in the connecting pipe 610. The second connecting pipe 220 is inserted in the connecting pipe 610 and the liquid guide pipe 120. The second connecting pipe 220 is connected to the liquid guide pipe 120 through the connecting pipe 610.

[0064] In some embodiments, the side wall of the liquid guide tube 120 is provided with a liquid guide hole 1201 communicating with the second liquid storage tank 102, and the second connecting tube 220 is connected to the second liquid storage tank 102 in sequence through the connecting tube 610, the liquid guide tube 120, the liquid guide hole 1201, and the second liquid storage tank 102.

[0065] In some embodiments, such as Figure 9 As shown, the first sealing element 500 has a groove 503 on the side near the second liquid storage chamber 102, and the end of the liquid guide tube 120 away from the connecting tube 610 is inserted into the groove 503 to fix the position of the liquid guide tube 120 and make the overall structure of the atomizing device 10 more stable.

[0066] In some embodiments, the first sealing member 500 is provided with a third through hole 501 in communication with the first storage tank 101, and the first communication pipe 210 is inserted into the third through hole 501, so that the first communication pipe 210 is in communication with the first storage tank 101 through the third through hole 501.

[0067] In some embodiments, as shown in Figure 4 the second storage tank 102 is provided with a storage member 150 for storing the atomized substrate, and the storage member 150 is arranged around the liquid guide pipe 120. The liquid guide hole 1201 extends along the length direction of the liquid guide pipe 120 to expand the area of the liquid guide hole 1201, so that the atomized substrate flowing out of the second communication pipe 220 can be fully injected into the storage member 150.

[0068] In some embodiments, the storage member 150 can be an oil storage cotton, and the material thereof can include flax cotton and oil-impregnated cotton.

[0069] In some embodiments, as shown in Figure 4 and Figure 6 the atomization device 10 includes a suction nozzle 130 arranged at the end of the first storage tank 101 away from the second storage tank 102. When a user normally uses the atomization device 10, the heights of the suction nozzle 130, the first storage tank 101 and the second storage tank 102 are sequentially reduced, and the height of the first storage tank 101 is greater than that of the second storage tank 102, so that the atomized substrate in the first storage tank 101 can spontaneously flow to the second storage tank 102 under the action of gravity.

[0070] In some embodiments, the first storage tank 101 is provided with a gas guide pipe 140, the first sealing member 500 is provided with a fourth through hole 502, the gas guide pipe 140 is inserted into the fourth through hole 502, the atomization core 110 is arranged in the second storage tank 102, and the atomization core 110 includes an atomization pipe 111 which is at least partially inserted into the fourth through hole 502 and sequentially communicates with the fourth through hole 502, the gas guide pipe 140 and the suction nozzle 130.

[0071] In some embodiments, the atomization core 110 is arranged on the side of the partition 410 close to the second storage tank 102. The atomization pipe 111 is provided with a heating member and a liquid guide member, the liquid guide member is wrapped on the heating member, and the liquid guide member is connected with the storage member 150 through the through hole formed on the atomization pipe 111 to guide the atomized substrate in the storage member 150 to the heating member, so that the atomized substrate is heated and atomized by the heating member to form an aerosol. The aerosol formed in the atomization pipe 111 can pass through the first storage tank 101 along the gas guide pipe 140 and be discharged from the suction nozzle 130. Specifically, the liquid guide member can be an oil guide cotton, and the heating member can be a heating wire or a heating mesh made of iron-chromium-aluminum, stainless steel, nickel-chromium alloy or the like.

[0072] In some embodiments, a third sealing member 420 is sealingly connected between the bracket 400 and the shell 300, and is arranged around the bracket 400 and abuts between the side wall of the bracket 400 and the side wall of the shell 300. The third sealing member 420 is made of a material such as silicone or rubber that is elastic.

[0073] In some embodiments, the shell 300, the suction nozzle 130 and the air guide pipe 140 can be integrally formed by injection molding to improve the sealing effect of the atomization device 10.

[0074] In some embodiments, as shown in Figure 11 the shell 300 includes the suction nozzle 130 and the air guide pipe 140, and the bracket 400 is accommodated in the shell 300. The first sealing member 500 divides the internal space formed by the shell 300 and the bracket 400 into the first liquid storage compartment 101 and the second liquid storage compartment 102, and the second liquid storage compartment 102 is in communication with the suction nozzle 130 and the air guide pipe 140. By cooperation between the shell 300, the bracket 400 and the first sealing member 500, the first liquid storage compartment 101 is closer to the suction nozzle 130 than the second liquid storage compartment 102, i.e., the height of the first liquid storage compartment 101 is higher than the height of the second liquid storage compartment 102 in normal use of the atomization device 10, so that the atomization substrate in the first liquid storage compartment 101 spontaneously flows to the second liquid storage compartment 102. The arrangement of the air guide pipe 140 enables the second liquid storage compartment 102 to bypass the first liquid storage compartment 101 and the suction nozzle 130 to communicate, which is simple in structure and is conducive to improving the sealing effect of the atomization device 10 and miniaturization of the atomization device 10.

[0075] In some embodiments, as shown in Figure 5 the atomization device 10 is provided with a liquid injection hole 301 and a sealing plug (not shown in the figure). The liquid injection hole 301 is used to communicate the first liquid storage compartment 101 with the outside, and the sealing plug is used to plug the liquid injection hole 301. Specifically, the liquid injection hole 301 is formed on the shell 300, and the user can inject the atomization substrate into the first liquid storage compartment 101 through the liquid injection hole 301. In normal use of the atomization device 10, the sealing plug plugs the liquid injection hole 301 to prevent the atomization substrate from leaking. When the atomization substrate in the first liquid storage compartment 101 is consumed, the sealing plug can be removed, and the atomization substrate from the outside can be injected into the first liquid storage compartment 101 through the liquid injection hole 301.

When the control valve 230 is powered on, the valve assembly 200 is in an open state, and when the control valve 230 is powered off, the valve assembly 200 is in a closed state.

[0079] In some embodiments, as shown in Figure 2 The atomization device 10 further includes a bottom cover 310 connected to the end of the shell 300 away from the mouthpiece 130, a containing cavity 401 is formed between the bracket 400 and the bottom cover 310, the battery 900, the pneumatic sensor 700 and the control circuit board 800 are all arranged in the containing cavity 401, and the battery 900 is electrically connected to the control circuit board 800 and the atomization core 110.

[0080] In some embodiments, the bottom cover 310 is provided with an electrode 320, the electrode 320 is electrically connected to the control circuit board 800, and an external power supply device can be electrically connected to the electrode 320 to supply power to the battery 900.

[0082] In some embodiments, the liquid injection hole 301 is arranged on the side of the shell 300 close to the electrode 320, and when the shell 300 is connected to the first shell, the liquid injection hole 301 is blocked by the first shell to improve the aesthetics of the atomization device 10.

[0083] The embodiments of the present application also provide a control method, which is applied to the atomization device 10 of the above-mentioned embodiments, as shown in Figure 12 The control method includes the following steps:

[0084] Step S100: Obtain the start signal sent by the pneumatic sensor 700.

[0085] Step S200: Accumulate the number of start times of the start signal.

[0086] Specifically, when the user uses the atomization device 10, the user performs suction at the suction nozzle 130, which can trigger the pneumatic sensor 700 to send a start signal. The control circuit board 800 is provided with a control circuit, which can acquire the start signal and accumulate the number of start times of the start signal. The number of start times represents the number of times the pneumatic sensor 700 is triggered, i.e., the number of times the user sucks the atomization device 10.

[0087] Step S300: Control the valve assembly 200 to switch between the open state and the closed state according to the number of start times.

[0088] When the valve assembly 200 is in the open state, the first liquid storage bin 101 and the second liquid storage bin 102 are in communication. When the valve assembly 200 is in the closed state, the first liquid storage bin 101 and the second liquid storage bin 102 are not in communication.

[0089] In some embodiments, as shown in FIG. 2, step S300 includes: Figure 13

[0090] Step S310: Determine whether the number of start times reaches a preset number of times.

[0091] Step S320: If the number of start times reaches the preset number of times, the valve assembly 200 is in the open state.

[0092] In some embodiments, when the atomization device 10 is not in use, the valve assembly 200 is in the closed state. When the user sucks the atomization device 10 multiple times, so that the number of start times reaches the preset number of times, the control circuit board 800 determines that the atomization substrate in the second liquid storage bin 102 is about to be depleted or has been depleted, and the valve assembly 200 is switched from the closed state to the open state, so that the first liquid storage bin 101 and the second liquid storage bin 102 are in communication, and the atomization substrate in the first liquid storage bin 101 can be supplemented to the second liquid storage bin 102.

[0093] In some embodiments, the preset number of times is a value preset by the control circuit of the control circuit board 800. The preset number of times can range from 50 to 150. Specifically, the preset number of times can be 50, 76, 100, 125, 150, or any value between the above-mentioned values.

[0094] Step S330: Determine whether the opening time of the valve assembly 200 in the open state reaches a preset time.

[0095] Step S340: If the opening time reaches the preset time, the valve assembly 200 is in the closed state.

[0096] ​In some embodiments, during the process of supplementing the atomization substrate in the first storage tank 101 to the second storage tank 102, when the atomization substrate in the second storage tank 102 is full, the communication between the first storage tank 101 and the second storage tank 102 needs to be disconnected to avoid the leakage caused by the excessive internal liquid pressure of the second storage tank 102. The control circuit of the control circuit board 800 can determine whether the opening time reaches the preset time. When the opening time reaches the preset time, it indicates that the atomization substrate in the second storage tank 102 is about to be full or has been full. At this time, the valve assembly 200 can be switched from the open state to the closed state to prevent the atomization substrate in the first storage tank 101 from flowing to the second storage tank 102.

[0097] Specifically, the preset time is a value set by the control circuit of the control circuit board 800 in advance. The range of the preset time can be 20s-40s. Specifically, the preset time can be 20s, 25s, 30s, 33.5s, 40s, and any value between the above-mentioned times.

[0098] Step S350: If the opening time reaches the preset time, the start-up number is reset to zero.

[0099] In some embodiments, when the opening time reaches the preset time, it indicates that the atomization substrate in the second storage tank 102 is about to be full or has been full. At this time, the start-up number can be reset to zero to re-calculate the start-up number, preparing for the next state switching of the valve assembly 200.

[0100] In some other embodiments, the valve assembly 200 can also have a control unit. When the opening time of the valve assembly 200 in the open state reaches the preset time, the valve assembly 200 can automatically switch to the closed state.

[0101] In some embodiments, the atomization device 10 can be provided with a sensor for detecting the remaining amount of the atomization substrate in the second storage tank 102. When the sensor detects that the remaining amount of the atomization substrate is lower than or equal to a first preset remaining amount, the sensor can send a first detection signal. The control circuit board 800 can receive the first detection signal and control the valve assembly 200 to switch to the open state. When the sensor detects that the remaining amount of the atomization substrate is higher than or equal to a second preset remaining amount, the sensor can send a second detection signal. The control circuit board 800 can receive the second detection signal and control the valve assembly 200 to switch to the closed state.

[0102] In some embodiments, the first preset remaining amount can be 0%-10% of the capacity of the second storage tank 102, indicating that the atomization substrate in the second storage tank 102 will be exhausted or has been exhausted. Specifically, the first preset remaining amount can be 0%, 2%, 5%, 10% of the capacity of the second storage tank 102, and any value between the above-mentioned percentages.

[0103] In some embodiments, the second preset residual amount can be 90% to 100% of the capacity of the second liquid storage tank 102, indicating that the atomized substrate in the second liquid storage tank 102 will be full or has been full. Specifically, the first preset residual amount can be 90%, 92.4%, 95%, 100% of the capacity of the second liquid storage tank 102, and any value between the above percentages.

[0104] In some embodiments, the control circuit board 800 can control the opening degree of the valve assembly 200 according to the residual amount of the atomized substrate in the second liquid storage tank 102, that is, control the flow rate of the atomized substrate from the first liquid storage tank 101 to the second liquid storage tank 102.

[0105] The atomization device 10 and the control method provided by the present application control the valve assembly 200 according to the number of starts of the pneumatic sensor 700, and further control the communication state between the first liquid storage tank 101 and the second liquid storage tank 102, so that the atomized substrate in the first liquid storage tank 101 can be controllably flowed to the second liquid storage tank 102. This is beneficial to reduce the volume of a single liquid storage tank, avoid the atomized substrate leakage problem caused by liquid pressure, improve the stability and reliability of the atomization device 10, ensure the sealing performance of the atomization device 10, and make the user can continuously use the atomization device 10 without additional operation, thereby improving the user experience.
