The present application will be described in detail with reference to the accompanying drawings and examples.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a first embodiment of a liquid storage assembly 10 according to the present invention. The liquid storage assembly 10 comprises a liquid storage cavity 11, a first detection terminal 12, a second detection terminal 13 and an atomization core 14.

The liquid storage cavity 11 is used for storing liquid to be atomized, the liquid to be atomized in the liquid storage cavity 11 can be guided to the atomizing core 14, and the liquid is heated and atomized in the atomizing core 14 to form aerosol for a user to use. In this embodiment, the liquid storage cavity 11 is disposed around the atomizing core 14, and in other embodiments, the liquid storage cavity 11 may be disposed on one side of the atomizing core 14.

The first detection terminal 12 includes a first conductive port 121, and the first conductive port 121 is disposed in the liquid storage chamber 11. The position of the first conductive port 121 corresponds to a first liquid level height, that is, when the liquid level height of the liquid in the liquid storage cavity 11 is greater than or equal to the first liquid level height, the first detection terminal 12 may be conductively connected to the liquid to be atomized in the liquid storage cavity 11 through the first conductive port 121; when the liquid level height of the liquid in the liquid storage cavity 11 is smaller than the first liquid level height, the first detection terminal 12 is insulated from the liquid to be atomized in the liquid storage cavity 11.

The second detection terminal 13 includes a second conductive port 131, and the second conductive port 131 is disposed in the liquid storage chamber 11. The position of the second conductive port 131 corresponds to a second liquid level height, that is, when the liquid level height of the liquid in the liquid storage cavity 11 is greater than or equal to the second liquid level height, the second detection terminal 13 may be conductively connected to the liquid to be atomized in the liquid storage cavity 11 through the second conductive port 131; when the liquid level height of the liquid in the liquid storage cavity 11 is smaller than the second liquid level height, the second detection terminal 13 is insulated from the liquid to be atomized in the liquid storage cavity 11.

The shapes of the first detection terminal 12 and the second detection terminal 13 may be a strip shape, a rod shape, or the like, or may be other shapes, and the present application is not limited thereto.

The detection terminal can be a part with a conductive port extending into the liquid storage cavity 11, and the other part is arranged outside the liquid storage cavity 11; or, all the detection terminals may be disposed in the liquid storage cavity 11, and it is only necessary that the conductive ports of the detection terminals are located at the liquid level height position corresponding to the liquid storage cavity 11.

The first detection terminal 12 and the second detection terminal 13 extend from one side of the liquid storage cavity 11 along a first direction, wherein the first direction may be a length direction or a width direction of the liquid storage cavity 11, and of course, the first direction may also extend into the liquid storage cavity 11 along other directions. In the present embodiment, the first detection terminal 12 and the second detection terminal 13 extend from one side of the reservoir 11 along the first direction and extend toward the other side of the reservoir 11 along the first direction, for example, the detection terminals may extend from one side of the reservoir 11 along the length direction and extend toward the other side of the reservoir 11 along the length direction; the detection terminal may also extend from one side of the reservoir 11 in the width direction and extend toward the other side of the reservoir 11 in the width direction. In other embodiments, both the first detection terminal 12 and the second detection terminal 13 may extend along one side of the length direction or the width direction, or one of the first detection terminal 12 and the second detection terminal 13 may extend along one side of the length direction and the other may extend along one side of the width direction.

The conductive port may be located at an end portion of the detection terminal or at a middle portion of the detection terminal. In this embodiment, the first conductive port 121 is located at the end of the extending direction of the first detection terminal 12, and the second conductive port 131 is located at the end of the extending direction of the second detection terminal 13. In other embodiments, the first conductive port 121 may be located at an intermediate section in the extending direction of the first detection terminal 12, and the second conductive port 131 may be located at an intermediate section in the extending direction of the second detection terminal 13. The position of the conductive port on the detection terminal is not limited to the several positions mentioned in the present application, and may be other positions, as long as the conductive port of the detection terminal is located at the liquid level height position corresponding to the liquid storage cavity 11.

The detection terminal only can be conductively connected with the liquid to be atomized in the liquid storage cavity 11 through the conductive port, and the outer surface of the part of the detection terminal except the conductive port is insulated from the liquid to be atomized in the liquid storage cavity 11. In this embodiment, the detection terminal may include a metal conductor, and an outer surface of a portion of the metal conductor is provided with an insulating layer, and an outer surface of another portion of the metal conductor is exposed to serve as a conductive port.

In one embodiment, the side surface of the first detection terminal 12 located in the liquid storage cavity 11 is insulated, and the cross section (end surface) of the port of the first detection terminal 12 located at one end of the liquid storage cavity 11 is conductive to form a first conductive port 121; the side surface of the second detection terminal 13 located in the reservoir chamber 11 is insulated, and the cross section (end surface) of the port of the end of the second detection terminal 13 located in the reservoir chamber 11 is conductive to form a second conductive port 131.

The side surface of the detection terminal is arranged to be insulated, the end surface of the detection terminal is arranged to be conductive and the process of the end surface of the detection terminal is simple, and the solution in the liquid storage cavity 11 can be conducted with the detection terminal when the liquid level of the solution in the liquid storage cavity 11 reaches the height of the cross section of the detection terminal in the liquid storage cavity 11.

The first and second

conductive ports

121 and 131 are used to electrically connect with the detection circuit 15. As shown in fig. 2 and fig. 3 is a schematic structural diagram of a third embodiment of the atomizer 10 according to the present invention, the reservoir assembly 10 may include a detection circuit 15, and the detection circuit 15 of the reservoir assembly 10 is electrically connected to the first conductive port 121 and the second conductive port 131. Of course, the detection circuit 15 may not be included in the reservoir assembly 10, and the first and second

conductive ports

121 and 131 may be electrically connected to an external detection circuit 15.

The detection circuit 15 may be directly electrically connected to the first conductive port 121 and the second conductive port 131, or may be electrically connected to a detection terminal disposed outside the liquid storage chamber 11, so as to be electrically connected to the conductive port in the liquid storage chamber 11 through a metal conductor inside the detection terminal. For example, the ports of the first detection terminal 12 and the second detection terminal 13 located at the end outside the reservoir 11 may be electrically connected, and the detection circuit 15 may be electrically connected to the first conductive port 121 and the second conductive port 131 by connecting the ports of the two detection terminals located at the end outside the reservoir 11.

The first conductive port 121 and the second conductive port 131 are electrically connected to the detection circuit 15, so that the detection circuit 15 detects the resistance of the liquid to be atomized in the liquid storage chamber 11 through the first conductive port 121 and the second conductive port 131, respectively, to determine the remaining amount of the liquid to be atomized.

It should be noted that the first liquid level height corresponding to the first detection terminal 12 is not equal to the second liquid level height corresponding to the second detection terminal 13, that is, the liquid level heights corresponding to the first conductive port 121 and the second conductive port 131 are different. The liquid level heights of the first and second

conductive ports

121 and 131 can be adjusted by setting the lengths of the first and

second detection terminals

12 and 13 to be different.

Through setting up first liquid level height and the high inequality of second liquid level to the surplus of treating atomizing liquid in stock solution chamber 11 is different, and the resistance that treats atomizing liquid that detection circuitry 15 detected through two detection terminal that electrically connect is different, thereby can confirm the surplus state of treating atomizing liquid in stock solution chamber 11.

For example, the first liquid level height may be set to be a liquid level height when the liquid in the liquid storage chamber 11 is full or close to the full, i.e. the first conductive port 121 may be disposed near the top wall of the liquid storage chamber 11; the second liquid level is a liquid level when the remaining amount of liquid in the liquid storage chamber 11 is small or no liquid at all, that is, the second conductive port 131 may be disposed near the bottom wall of the liquid storage chamber 11.

With this arrangement, when the liquid level of the liquid in the liquid storage chamber 11 is lower than the second liquid level, the first conductive port 121 and the second conductive port 131 are both insulated from the liquid in the liquid storage chamber 11, i.e. the first detection terminal 12 and the second detection terminal 13 cannot be conductively connected with the liquid in the liquid storage chamber 11. The resistance value of the liquid to be atomized, which is detected by the detection circuit 15 through the first conductive port 121 and the second conductive port 131, is infinite (equivalent to that the detection terminal is open circuit), so that the residual amount of the liquid in the liquid storage cavity 11 can be determined to be less or no liquid at all, that is, the residual amount of the liquid to be atomized is determined to be oil-free, and then the user needs to be reminded to replenish the liquid to be atomized.

When the liquid level of the liquid in the liquid storage cavity 11 is higher than the first liquid level height and the second liquid level height, the first conductive port 121 and the second conductive port 131 are both in conductive connection with the liquid in the liquid storage cavity 11. The liquid to be atomized, which is detected by the detection circuit 15 through the first conductive port 121 and the second conductive port 131, has a certain resistance value, so that it can be determined that the remaining amount of the liquid in the reservoir chamber 11 is full of oil.

When the liquid level of the liquid in the liquid storage cavity 11 is higher than or equal to the second liquid level height and is smaller than the first liquid level height, the first conductive port 121 is insulated from the liquid in the liquid storage cavity 11, and the second conductive port 131 is conductively connected with the liquid in the liquid storage cavity 11. The resistance value of the liquid to be atomized, detected by the detection circuit 15 through the first conductive port 121, is infinite, and the liquid to be atomized, detected by the second conductive port 131, has a certain resistance value, so that the residual amount of the liquid in the liquid storage cavity 11 can be determined to be between oil-free and oil-full (half oil).

In other embodiments, the first liquid level height and the second liquid level height may be set as required, for example, when the remaining amount of the liquid to be atomized is more than 80% of the capacity of the liquid storage chamber 11, the remaining amount state of the liquid is considered to be full of oil, and the first liquid level height is the liquid level height when the remaining amount of the liquid to be atomized is 80% of the capacity of the liquid storage chamber 11; when the residual amount of the liquid to be atomized is less than 20% of the capacity of the liquid storage cavity 11, the residual amount of the liquid is considered to be oil-free, and the second liquid level height is the liquid level height when the residual amount of the liquid to be atomized is 20% of the capacity of the liquid storage cavity 11.

The utility model provides a stock solution subassembly 10 compares in prior art, because two electrically conductive ports of first electrically conductive port 121 and second electrically conductive port 131 have been set up in stock solution chamber 11, detection electrode and reference electrode have been set up in stock solution chamber 11 promptly, thereby when detection circuit 15 detects the liquid of treating atomizing, can judge the surplus of the liquid of treating atomizing through the relative value of detection electrode and reference electrode, the design of the liquid surplus of treating atomizing is detected simply, therefore, the carrier wave prepaid electric energy meter is low in cost, and judge the surplus through the mode that two detection terminals compare, avoided detection circuit 15 to influence the condition that detects the precision because the resistance change of the liquid of treating atomizing in stock solution chamber 11, the testing result is difficult to produce the erroneous judgement problem.

Referring to fig. 3, fig. 3 is a schematic structural diagram of a liquid storage assembly 10 according to a third embodiment of the present invention. In one embodiment, the detection circuit 15 includes a detection unit 151 and a control unit 152.

The sensing unit 151 electrically connects the first conductive port 121 and the second conductive port 131. Specifically, the detecting unit 151 obtains a first electrical signal by detecting the first conductive port 121, and obtains a second electrical signal by detecting the second conductive port 131. The control unit 152 is connected to the detection unit 151. The control unit 152 can determine a first resistance value of the liquid to be atomized according to the first electrical signal, determine a second resistance value of the liquid to be atomized according to the second electrical signal, and determine the remaining amount of the liquid to be atomized through the first resistance value and the second resistance value.

Specifically, the control unit 152 has an ADC conversion module, a calculation module, and a judgment module. The ADC conversion module can convert the analog signal into a digital signal, and the ADC conversion module can determine a first voltage value according to the first electric signal. The calculation module can calculate a first resistance value of the liquid to be atomized according to the first voltage value. Similarly, the ADC conversion module can determine a second voltage value according to the second electric signal, and the calculation module calculates a second resistance value of the liquid to be atomized according to the second voltage value.

In one embodiment, as shown in fig. 3, the determining module can determine the remaining amount of the liquid to be atomized by the first resistance value and the second resistance value. In this embodiment, the first liquid level is greater than the second liquid level, and it can be set that when the resistance value is greater than or equal to a preset threshold value, the liquid is considered to be insulated from the conductive port, and when the resistance value is less than the preset threshold value, the liquid is considered to be conducted with the conductive port. For example, when the first resistance value is greater than or equal to 1M Ω, the liquid to be atomized in the reservoir 11 is considered to be insulated from the first conductive port 121, and when the first resistance value is less than 1M Ω, the liquid to be atomized in the reservoir 11 is considered to be conductively connected to the first conductive port 121.

Specifically, when the judgment module judges that the first resistance value and the second resistance value are both greater than or equal to the preset threshold value, that is, when the liquid to be atomized is insulated from the first conductive port 121 and the second conductive port 131, it is determined that the remaining amount of the liquid to be atomized is oil-free.

The judgment module judges that the first resistance value is larger than or equal to a preset threshold value, and the second resistance value is smaller than the preset threshold value, namely, the liquid to be atomized is insulated from the first conductive port 121, and when the liquid to be atomized is in conductive connection with the second conductive port 131, the residual amount of the liquid to be atomized is determined to be in a semi-oil state.
