Referring to Figures 2 to 4, Figure 3 is a schematic structural diagram of an embodiment of the atomizer provided by the present application, and Figure 4 is an enlarged view of part A in Figure 3. As shown in Figure 2, the atomizer 100 includes a liquid storage tank 110, a buffer assembly 120, an atomization assembly 130, a one-way valve 140, a detection element 150, a base assembly 160, two heating electrodes 170 and a top cover assembly 180. The top cover assembly 180 and the buffer assembly 120 are respectively arranged at opposite ends of the liquid storage tank 110. The atomization assembly 130 is assembled on the buffer assembly 120. The base assembly 160 is connected to one end of the buffer assembly 120 away from the liquid storage tank 110. Two The heating electrode 170 is disposed on the base assembly 160 and is electrically connected to the atomization assembly 130. The one-way valve 140 is disposed on the liquid conduction channel connecting the liquid storage bin 110 and the cache assembly 120 to conduct or cut off the liquid conduction channel. The detection element 150 is assembled on the cache assembly 120 and the base assembly 160, and is used to electrically connect the heating element of the atomization assembly 130 through the liquid in the cache cavity 1201 of the cache assembly 120.

Among them, the liquid storage chamber 110 has a liquid storage chamber 1101 and a lower liquid hole 1102. The lower liquid hole 1102 is connected with the liquid storage chamber 1101, and the liquid storage chamber 1101 is used to cache the liquid substrate. The cache component 120 is connected to the liquid storage bin 110. The cache component 120 has a cache cavity 1201 and a liquid inlet hole 1202. The liquid inlet hole 1202 is connected with the cache cavity 1201, and the liquid inlet hole 1202 corresponds to the lower liquid hole 1102. The liquid inlet hole 1202 It is connected with the lower liquid hole 1102 to form a liquid conduction channel. The liquid storage chamber 1101 and the buffer chamber 1201 are in fluid communication through the liquid channel. The buffer cavity 1201 is used to temporarily store the liquid matrix provided from the liquid storage chamber 1101.

Relatively speaking, the liquid storage cavity 1101 is a large-capacity cavity, and the buffer cavity 1201 is a small-capacity cavity. For example, the capacity in the liquid storage cavity 1101 is 50 ml, and the capacity in the buffer cavity 1201 is 2 ml. The liquid storage chamber 110 can be filled each time. Inject a small amount of liquid matrix into the cache component 120; that is, the liquid matrix in the atomizer 100 is divided into two parts: storage and ready-to-use, and are located in the liquid storage chamber 1101 and the cache chamber 1201 respectively. The liquid storage chamber 110 is used to store liquid The buffer component 120 is used to temporarily store the liquid matrix to be atomized, and when the one-way valve 140 is closed, the liquid storage chamber 1101 and the buffer component 120 are isolated. Since the amount of liquid stored in the buffer component 120 is small, the resulting The hydraulic pressure is also low and the risk of leakage through the atomizer assembly 120 is significantly reduced.

The one-way valve 140 is installed in the liquid guide channel, and can be installed at both ends of the liquid guide channel: the lower liquid hole 1102 And/or the liquid inlet hole 1202 is used to connect or close the liquid channel of the buffer chamber 1201 and the liquid storage chamber 1101. The atomization component 130 is assembled on the cache component 120 and is in contact with the cache cavity 1201. The atomization component 130 includes a heating element 1301. The atomization component 130 is used to absorb the liquid substrate in the cache cavity 1201 and atomize the liquid substrate; the detection element 150 is assembled to the cache assembly 120 and is used to electrically connect with the heating element 1301 through the liquid in the cache cavity 1201 .

It can be understood that in this application, the atomization assembly 130 and the detection element 150 are assembled in the cache assembly 120, and the atomization assembly 130 is connected with the cache cavity 1201 to facilitate the suction of liquid from the cache cavity 1201, and the cache cavity 1201 is temporarily stored in the cache cavity 1201. The heating element 1301 of the atomization component 130 is electrically connected to the detection element 150 through the liquid matrix.

In response to the disconnection between the detection element 150 and the heating element 1301, the one-way valve 140 is opened to connect the lower liquid hole 1102 and the liquid inlet hole 1202, that is, the liquid storage chamber 1101 is connected with the buffer chamber 1201, and the liquid matrix in the liquid storage chamber 1101 passes through the lower liquid hole 1102 and the liquid inlet hole 1202. The liquid hole 1102 and the liquid inlet hole 1202 enter the buffer cavity 1201 to inject liquid into the buffer cavity 1201; in response to the detection element 150 being connected to the heating element 1301 for a preset period of time, that is, after a certain amount of liquid matrix is injected into the buffer cavity 1201 , the one-way valve 140 is closed, so that the passage between the lower liquid hole 1102 and the liquid inlet hole 1202 is cut off, that is, the liquid storage chamber 1101 and the buffer chamber 1201 are not connected. In this way, no matter when the electronic atomization device is transported or put aside, the amount of liquid stored in the buffer cavity 1201 is small, that is, the amount of liquid contacted by the atomization assembly 130 is less and the hydraulic pressure is low, which can effectively reduce the amount of liquid passing through the atomization assembly 130. The amount of liquid that volatilizes or leaks, and the liquid matrix in the liquid storage chamber 1101 will not volatilize into the air because it is isolated, which reduces the waste of liquid matrix and ensures the taste of the atomized aerosol.

In this embodiment, the liquid storage tank 110, buffer assembly 120, atomization assembly 130, one-way valve 140, detection element 150, base assembly 160, two heating electrodes 170 and top cover assembly 180 in the atomizer 100 are all The atomizer 100 is formed from independent parts and components through assembly lines. In other embodiments, the liquid storage tank 110 and the cache assembly 120 can also be two parts of the same component, which is made using an integrated molding process, such as injection molding or pouring, or the detection element 150 can also be embedded in injection molding. On the cache component 120 or the base component 160, the cache component 120 and the base component 160 can also be two parts of the same component, or the base component 160 and the top cover component 180 can be two parts of the same component, or Liquid storage tank 110. The cache assembly 120, the base assembly 160 and the top cover assembly 180 are four parts of the same component; in other words, the liquid storage tank 110, the cache assembly 120, the atomization assembly 130, the one-way valve 140, the detection element 150, and the base Any two or more of the assembly 160, the two heating electrodes 170 and the top cover assembly 180 can constitute one component, and will not be described again.

The detection element 150 includes a conductive terminal 1501 and a detection electrode 1502 that are electrically connected to each other. One end of the conductive terminal 1501 can be located in the liquid conduction channel or the buffer cavity 1201, and is used to realize the detection through the liquid in the buffer cavity 1201 and the heating element 1301. Electrical connection.

In one embodiment, the conductive terminal 1501 is a metal terminal; in another embodiment, the conductive terminal 1501 is a non-metal terminal, and its surface is coated with a conductive coating.

The main unit 200 also includes an electrical connector (not shown), which is electrically connected to the main unit 200. After the atomizer 100 and the main unit 200 are assembled, the electrical connector is electrically connected to the detection electrode 1502 and thus to the conductive terminal 1501. Electrical connection. The electrical connector may be a conductive rod or a conductive blind tube.

The detection electrode 1502 can be in the shape of a tube to be plugged into the electrical connector; or the detection electrode 1502 can also be a conductive cylinder.

In this embodiment, the detection element 150 is in the shape of a hollow tube as a whole, and the liquid matrix in the buffer cavity 1201 is also filled in the detection element 150. The electrical connector of the host 200 is inserted into the detection electrode 1502 and passes through the liquid matrix and the detection electrode. 1502 electrical connection.

It can be understood that the detection element 150 and the heating element 1301 form a detection circuit through the liquid matrix for detecting the amount of the liquid matrix in the buffer cavity 1201; the controller 220 controls the closing or closing of the one-way valve 140 according to the conduction or disconnection of the detection circuit. Open, thereby making the liquid storage chamber 1101 and the cache chamber 1201 disconnected or connected.

Optionally, the conductive terminal 1501 of the detection element 150 may be a conductive sheet or a conductive rod, which is not specifically limited in this application.

In one embodiment, the conductive terminal 1501 is a conductive sheet, and any conductive terminal 1501 can be combined with the heating element 1301 to form a detection circuit through a liquid matrix, in which the conductive terminal 1501 and the heating element 1301 serve as one of the positive and negative electrodes of the detection circuit respectively. . When the liquid matrix level in the buffer cavity 1201 is lower than the heating The height of the component 1301, the detection circuit is disconnected, the controller 220 controls the one-way valve 140 to open, the liquid storage chamber 110 and the buffer chamber 1201 are connected, so that the liquid matrix in the liquid storage chamber 1101 enters through the lower liquid hole 1102 and the liquid inlet hole 1202 Cache cavity 1201 to replenish the liquid matrix in the cache cavity 1201; when the liquid matrix level in the cache cavity 1201 is gradually higher than the height of the heating element 1301, the liquid matrix simultaneously contacts the heating element 1301 and the conductive terminal 1501, that is, the heating element 1301 and the conductive terminal 1501. The conductive terminal 1501 is electrically connected, and the detection circuit is turned on. Since the cache cavity 1201 needs to inject enough liquid substrate to heat and atomize, the controller 220 responds to the detection circuit being turned on for a certain period of time, and then controls the one-way valve 140 to close. The liquid conduction channel connecting the lower liquid hole 1102 to the liquid inlet hole 1202 is cut off, that is, the liquid storage cavity 1101 is not connected to the buffer cavity 1201, thereby preventing excess liquid matrix in the buffer cavity 1201 from causing liquid leakage.

In some embodiments, the liquid matrix injected into the cache cavity 1201 can be 10 to 30 mg each time, and the time for each liquid injection is 1 to 3 seconds. Using the solution of this application, the liquid matrix in the atomization component 130 will not leak and can be replenished in time. The quality of the liquid matrix and aerosol can also be ensured, which improves the user experience.

The number of detection elements 150 can be one or more, and can further form one or more detection circuits with the heating element 1301 . For example, if the number of conductive terminals 1501 is multiple and the plurality of conductive terminals 1501 are distributed around the atomization component 130, tilt detection can be performed to avoid that when the electronic atomization device 300 is relatively tilted, the detection circuit on one side will be disconnected, thereby causing an open circuit on one side. When there is still a large amount of liquid substrate in the buffer cavity 1201, a larger amount of liquid is injected into the buffer cavity 1201 again, causing the liquid amount in the buffer cavity 1201 to be overloaded and prone to leakage.

Optionally, the number of conductive terminals 1501 can be 2, 3 or 4, etc., and are arranged around the atomizer assembly 130. When at least one of the plurality of conductive terminals 1501 is connected to the detection circuit composed of the heating element 1301, then By continuing to keep the one-way valve 140 closed, the electronic atomizer device can be prevented from blindly injecting liquid into the buffer chamber 1201 in a tilted state; when multiple detection circuits composed of multiple conductive terminals 1501 and heating elements 1301 are all open circuits, then The controller 220 controls the one-way valve 140 to open to inject liquid into the buffer chamber 1201 .

Optionally, in another embodiment, the number of conductive terminals 1501 is two, and the two conductive terminals 1501 and the heating element 1301 form two detection circuits respectively through a liquid matrix, wherein one conductive terminal 1501 and the heating element 1301 form The first branch, another conductive terminal 1501 and the heating element 1301 form a second The first branch and the second branch can respectively correspond to the first preset value and the second preset value for detecting the liquid level in the buffer cavity 1201, where the first preset value is smaller than the second preset value, and the first The preset value and the second preset value can be set according to actual production requirements, and are not limited in this embodiment.

Specifically, in response to the first branch circuit being disconnected, the one-way valve 140 is opened to inject liquid into the cache cavity 1201; in response to the second branch circuit being opened, the one-way valve 140 is closed to stop injecting liquid into the cache cavity 1201. . In other words, when the liquid level in the buffer cavity 1201 is lower than the first preset value, liquid injection starts, and when the liquid level in the buffer cavity 1201 is higher than the second preset value, liquid injection stops.

The cache assembly 120 includes a mounting base 1203, and the top cover assembly 180 includes a top cover 181. The mounting base 1203 is open at one end, and the liquid storage tank 110 is located at an end of the mounting base 1203 away from the open end and is connected to the top cover 181. There is a suction channel 1218 in the liquid tank 110, and a suction port 1810 is provided on the top cover 181 at an end away from the liquid storage tank 110. The suction port 1810 communicates with the suction channel 1218 and the atomization chamber of the atomization assembly 130.

The top cover 181 is also provided with a ventilation hole 1812, which is connected with the liquid storage chamber 1101 to facilitate the drainage of liquid in the liquid storage chamber 1101. The liquid storage tank 110 and the mounting base 1203 are detachably connected, specifically, through magnetic connection or plug-in connection.

Referring to Figures 3, 7 and 8 in combination, Figure 7 is a schematic top structural view of the mounting base in the atomizer shown in Figure 3, and Figure 8 is a schematic cross-sectional structural view of the mounting base shown in Figure 7. The mounting base 1203 has a buffer cavity 1201, a liquid inlet hole 1202, and parallel first and second mounting holes 1211 and 1212. The buffer cavity 1201 is connected to the liquid inlet hole 1202, the first and second mounting holes 1211 and 1212. , the first mounting hole 1211 and the second mounting hole 1212 are both provided on the bottom wall of the cache cavity 1201 .

The ventilation member 182 is provided with a ventilation channel 1821. The ventilation channel 1821 includes a first sub-channel 1822 and a second sub-channel 1823 arranged in a circuitous manner. The first sub-channel 1822 is spaced apart from the outer wall of the ventilation member 182 and is opened vertically. In the ventilation part 182; the second sub-channel 1823 is provided on the outer wall of the ventilation part 182, with a gap between it and the inner surface of the top cover 181, and with the side wall of the top cover 181.

In addition, a plurality of liquid collection tanks 1825 are provided on the side wall of the second sub-channel 1823 for collecting the liquid substrate leaking from the ventilation channel 1821.
