Description

Technical Field

[0001] The utility model relates to the technical field of electronic atomizer testing, in particular to a high and low voltage test control circuit for an electronic atomizer. Background Art

[0002] An electronic atomizer is an electronic product that imitates cigarettes. Although there are various models and styles of electronic atomizers, they generally consist of three parts: a battery, an atomizer, and a cartridge. After being used for a certain period of time, the existing electronic atomizers generally need to be charged. In order to ensure normal charging of the electronic atomizer during subsequent use by consumers, before leaving the factory, the electronic atomizer needs to be subjected to high-voltage DC7.5V protection and low-voltage DC5.0V charging tests. However, in actual production, it is often necessary for workers to manually test the DC7.5V protection state at the same station first, and then test the DC5.V charging state, which easily leads to missed tests and requires manual plugging and unplugging twice, resulting in slow test efficiency. Summary of the Utility Model

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a high and low voltage test control circuit for an electronic atomizer.

[0028] Please refer to Figure 1 , Figure 1 which is a schematic block diagram of a high-low voltage test control circuit for an electronic atomizer provided by an embodiment of the present utility model, including: a high-voltage tester 10, a low-voltage tester 20, a control module 30, and a connector 40. One end of the control module 30 is electrically connected to the high-voltage tester 10 and the low-voltage tester 20, and the other end is electrically connected to the connector 40. The connector 40 is used to be electrically connected to the electronic atomizer. The high-voltage tester 10 is used to perform a high-voltage test on the electronic atomizer, the low-voltage tester 20 is used to perform a low-voltage test on the electronic atomizer, and the control module 30 is used to switch the high-voltage tester 10 or the low-voltage tester 20 to work.

[0029] Among them, this control circuit is mainly used in the field of electronic atomizer charging test, providing automated high-low voltage tests for the electronic atomizer to simplify the test process of the electronic atomizer. And because the test process realizes automated and programmed control, it reduces the risk of missed tests caused by human factors. Each electronic atomizer will automatically complete high-voltage and low-voltage tests according to the preset program, ensuring the comprehensiveness and accuracy of the test, that is, improving the test efficiency, reducing the cost, and enhancing the reliability of the test results. In addition, by reducing manual intervention and repetitive labor, this technology reduces the labor cost in the test process. At the same time, due to the optimization of the test process, it also reduces the rework cost caused by improper testing or missed testing. In addition, automated testing not only improves the test speed, but also increases the overall test efficiency because it reduces human errors and improves the stability of the test. In addition, because the test process is strictly controlled by procedures, the test results are more reliable and consistent, which helps enterprises better evaluate product quality and ensure that only qualified products can enter the market.

[0030] Specifically, the voltage output by the high-voltage tester 10 is 7.5V, and the voltage output by the low-voltage tester 20 is 5.0V. The connector 40 is a Type-C connector. By inserting the Type-C connector into the electronic atomizer and then starting the control circuit, the high-voltage DC 7.5V is first tested, that is, whether there is current is displayed through the high-voltage tester 10. If no current is displayed, it means the test is OK (qualified); if current is displayed, the tester alarms and the product is NG (unqualified). After the high-voltage test is completed, the control circuit automatically switches to the low-voltage DC 5.0V to test whether the charging current is within the range of 260 - 800mA. If the current value displayed by the low-voltage tester 20 is within this range, it means the test is OK (qualified); if the current value displayed by the low-voltage tester 20 exceeds this range, the tester alarms and the product is NG (unqualified).

[0031] Specifically, both the high-voltage tester 10 and the low-voltage tester 20 adopt existing publicly known technologies and will not be elaborated here in detail.

[0032] In one embodiment, referring to Figures 2 to 3 as shown, the control module 30 includes a power transformer T, a foot switch SB, a time relay KT1, a time relay KT2, a time relay KT3, a intermediate relay KM1, a intermediate relay KM2, and a intermediate relay KM3. The foot switch SB, the normally open contacts KM10 and KM11 of the intermediate relay KM1, the normally open contact KT11 of the time relay KT1, and the normally open contact KT30 of the time relay KT3 are connected to the positive pole of the power transformer T. One end of the normally closed contact KT20 of the time relay KT2 is connected to the foot switch SB and the normally open contact KM10 of the intermediate relay KM1, and the other end is connected to the intermediate relay KM1. The time relay KT1 and its normally closed contact KT10 are connected to the normally open contact KM11 of the intermediate relay KM1. The intermediate relay KM2 is connected to the normally closed contact KT10 of the time relay KT1. The time relay KT3 is connected to the normally open contact KT11 of the time relay KT1. The intermediate relay KM3 and the time relay KT2 are connected to the normally open contact KT30 of the time relay KT3. The time relays KT1, KT2, KT3, the intermediate relays KM1, KM2, and KM3 are also connected to the negative pole of the power transformer T.

[0033] Specifically, the power transformer T is used to convert 220V alternating current into 12V direct current for the control module 30 to ensure the stable operation of the entire control module 30 and the safe use of electrical components. Among them, the foot switch SB serves as the start signal source of the control module 30. When the foot switch SB is pressed, the circuit is connected, triggering the subsequent control logic; the time relays KT1, KT2, and KT3 are used to achieve precise time control to ensure that each electrical component operates in a predetermined time sequence; the intermediate relays KM1, KM2, and KM3 are used to increase the flexibility and reliability of the control circuit and implement complex control logic.

[0034] In one embodiment, as shown in Figures 2 to 3 the positive electrode of the high-voltage tester 10 is connected to the normally open contact KM20 of the intermediate relay KM2. One end of the normally closed contact KM32 of the intermediate relay KM3 is connected to the normally open contact KM20 of the intermediate relay KM2, and the other end is connected to the connector 40. The negative electrode of the high-voltage tester 10 is connected to the normally open contact KM21 of the intermediate relay KM2. One end of the normally closed contact KM33 of the intermediate relay KM3 is connected to the normally open contact KM21 of the intermediate relay KM2, and the other end is connected to the connector 40. The positive electrode of the low-voltage tester 20 is connected to the normally open contact KM30 of the intermediate relay KM3. One end of the normally closed contact KM22 of the intermediate relay KM2 is connected to the normally open contact KM30 of the intermediate relay KM3, and the other end is connected to the connector 40. The negative electrode of the low-voltage tester 20 is connected to the normally open contact KM31 of the intermediate relay KM3. One end of the normally closed contact KM23 of the intermediate relay KM2 is connected to the normally open contact KM31 of the intermediate relay KM3, and the other end is connected to the connector 40.

[0035] Specifically, the positive electrode of the high-voltage tester 10 is connected to the normally open contact KM20 of the intermediate relay KM2, and the negative electrode is connected to the normally open contact KM21 of the intermediate relay KM2. This connection method means that the power on and off of the high-voltage tester 10 is controlled by the normally open contact of the intermediate relay KM2. The normally closed contacts KM32 and KM33 of the intermediate relay KM3 are respectively connected across the normally open contacts KM20 and KM21 of the intermediate relay KM2 and are connected to the connector 40 to cut off the power path of the high-voltage tester 10 to provide protection. The positive electrode of the low-voltage tester 20 is connected to the normally open contact KM30 of the intermediate relay KM3, and the negative electrode is connected to the normally open contact KM31 of the intermediate relay KM3, so that the power on and off of the low-voltage tester 20 is controlled by the normally open contact of the intermediate relay KM3. The normally closed contacts KM22 and KM23 of the intermediate relay KM2 are respectively connected across the normally open contacts KM30 and KM31 of the intermediate relay KM3 and are connected to the connector 40 to affect the power path of the low-voltage tester 20 by the disconnection of its normally closed contacts. That is, by the on and off states of the intermediate relays, the power on and off of the high-voltage tester 10 and the low-voltage tester 20 can be flexibly controlled; when the intermediate relay KM2 or the intermediate relay KM3 operates, the power of the corresponding tester can be automatically cut off or connected, thereby realizing the safety control and protection of the test process. This connection method can be used to implement complex test logics, for example: automatically switching to low-voltage testing after high-voltage testing is completed.

[0036] In one embodiment, referring to Figure 3 as shown, when the foot switch SB is depressed, the intermediate relay KM1 is energized at this time, and the normally open contacts KM10 and KM11 of the intermediate relay KM1 are closed simultaneously. When the foot switch SB is released, the foot switch SB resets and disconnects, and the normally open contact KM10 of the intermediate relay KM1 provides current for the intermediate relay KM1.

[0037] Specifically, when the operator steps on the foot switch SB, it is activated as an electrical switch, closing the connected circuit. In this scenario, the closing of the foot switch SB provides the energizing condition for the intermediate relay KM1. When the foot switch SB is closed, the intermediate relay KM1 is energized. After being energized, the normally open contacts KM10 and KM11 of the intermediate relay KM1 will close simultaneously, which means that the intermediate relay KM1 not only responds to the trigger of the foot switch SB but also provides an electrical connection for the subsequent circuit through the closing of its contacts KM10 and KM11. When the foot switch SB is released, the foot switch SB will reset and open. However, at this time, the normally open contact KM10 of the intermediate relay KM1 provides current for KM1 itself, realizing a self-locking function. This self-locking function means that once the intermediate relay KM1 is activated, it will remain activated even if the original trigger source (foot switch SB) has been disconnected. This is usually used in scenarios that require continuous operation or maintaining a state. That is, when the operator steps on the self-resetting foot switch SB (which will automatically disconnect), the intermediate relay KM1 is immediately energized. Then, the normally open contacts KM10 and KM11 of the intermediate relay KM1 will close simultaneously. In actual operation, since the operator's foot leaves the self-resetting foot switch SB instantaneously after stepping on it, the foot switch SB resets and disconnects the circuit. But for the intermediate relay KM1 to continue to be energized, it can only be provided by its normally open contact KM10 self-locking the circuit for it.

[0038] In one embodiment, refer to Figure 3 As shown, when the normally open contact KM11 of the intermediate relay KM1 closes, at this time, the intermediate relay KM2 and the time relay KT1 are energized. The normally open contacts KM20 and KM21 of the intermediate relay KM2 close simultaneously, and the normally closed contacts KM22 and KM23 of the intermediate relay KM2 open simultaneously. The high-voltage tester 10 is turned on and performs a high-voltage test on the electronic atomizer through the connector 40.

[0039] Specifically, when the normally open contact KM11 of the intermediate relay KM1 closes, it acts as a switch for the power path, enabling the intermediate relay KM2 and the time relay KT1 to be energized. This chain reaction ensures that only when a specific condition is met (i.e., the KM11 contact of KM1 is closed), the intermediate relay KM2 and the time relay KT1 will be activated, thereby achieving precise control of the circuit state. Additionally, after the intermediate relay KM2 is energized, its normally open contacts KM20 and KM21 close simultaneously, providing an electrical connection for the high-voltage tester 10. At the same time, the normally closed contacts KM22 and KM23 of the intermediate relay KM2 open, used to cut off other unnecessary circuit paths or provide safety isolation. Moreover, due to the closing of the normally open contacts KM20 and KM21 of the intermediate relay KM2, the high-voltage tester 10 is connected and is connected to the electronic atomizer through the connector 40, enabling the high-voltage tester 10 to perform a high-voltage test on the electronic atomizer. Additionally, the normally closed contacts KM22 and KM23 of the intermediate relay KM2 open simultaneously, achieving circuit interlocking. Even if the intermediate relay KM3 is accidentally energized, causing the normally open contacts KM30 and KM31 of the intermediate relay KM3 to close, in the control circuit, the low-voltage tester 20 and the electronic atomizer are effectively isolated from the high and low circuits because the normally closed contacts KM22 and KM23 of the intermediate relay KM2 are in an open state.

[0040] In one embodiment, referring to Figure 3 as shown, when the time relay KT1 is energized and after waiting for the set time to arrive, the time relay KT1 starts to work. At this time, the normally closed contact KT10 of the time relay KT1 opens, and the normally open contact KT11 closes, causing the intermediate relay KM2 to lose power. The normally open contacts KM20 and KM21 of the intermediate relay KM2 reset and open simultaneously, and the normally closed contacts KM22 and KM23 of the intermediate relay KM2 reset and close simultaneously. The high-voltage tester 10 is powered off to end the high-voltage test on the electronic atomizer.

[0041] Specifically, the main function of the time relay KT1 is to provide a time delay function. When the time relay KT1 is powered on, it will wait for a preset time period (i.e., the set time, for example: 0.2 - 1 second). The length of this time period can be adjusted according to needs to adapt to different test requirements. When the set time arrives, the time relay KT1 starts to work, and the state of its contacts changes. Specifically, the normally closed contact KT10 will open, and the normally open contact KT11 will close. This contact switching is a common signal transmission method in the control circuit. Since the normally open contact KT11 of the time relay KT1 closes, it connects to a circuit path that de-energizes the intermediate relay KM2. Therefore, when KT11 closes, the intermediate relay KM2 will lose power. After the intermediate relay KM2 loses power, its normally open contacts KM20 and KM21 will simultaneously reset and open, which means that the circuit paths they were previously connected to are cut off. This is usually used to disconnect the electrical connection with the high-voltage tester 10 or other devices. At the same time, the normally closed contacts KM22 and KM23 of the intermediate relay KM2 will simultaneously reset and close. The closing of these contacts is used to restore other circuit paths that were previously disconnected by the intermediate relay KM2, or to prepare for subsequent circuit operations. Additionally, due to the opening of the normally open contacts KM20 and KM21 of the intermediate relay KM2, the circuit path connected to the high-voltage tester 10 is cut off, causing the high-voltage tester 10 to lose power. This is a crucial step in ending the high-voltage test of the electronic atomizer. The power-off of the high-voltage tester 10 ensures the safety and controllability of the test process. It prevents possible accidents during the test, such as overvoltage and overcurrent, thus protecting the test equipment and the electronic atomizer under test. That is, when the normally closed contact KT10 of the time relay KT1 opens, it causes the intermediate relay KM2 to lose power at this time. At this time, the normally open contacts KM20 and KM21 of the intermediate relay KM2 simultaneously reset and open, and the normally closed contacts KM22 and KM23 of the intermediate relay KM2 simultaneously reset and close to return to the initial state. At this time, due to the simultaneous reset and opening of the normally open contacts KM20 and KM21 of the intermediate relay KM2, the high-voltage tester 10 disconnects the circuit and no longer performs the high-voltage test.

[0042] In one embodiment, when the normally open contact KT11 of the time relay KT1 closes, it causes the time relay KT3 to be powered on. The purpose of the time relay KT3 in the circuit is to set a very short time (for example: 0.2 - 1 second) so that after the high-voltage tester 10 finishes the test and returns to its original position, there is a small buffer to prepare for the test of the low-voltage tester 20.

[0043] Specifically, the small time delay set by the time relay KT3 provides a slight buffer period for the high-voltage tester 10 after it completes the test. This time delay allows the high-voltage tester 10 to have sufficient time to stabilize its internal state after completing its test task. Additionally, by setting this time buffer between the high-voltage tester 10 and the low-voltage tester 20, it can be ensured that the low-voltage tester 20 starts the test only after the high-voltage tester 10 has completely stopped working and is in a safe state. This helps prevent interference or conflicts between the two testers, thereby improving the safety of the test process. Moreover, the introduction of the time relay KT3 makes the test process smoother and more efficient. It ensures that the switching between the testers is orderly, avoiding test errors or equipment damage caused by too rapid switching. Conducting the low-voltage test immediately after the high-voltage test may cause the test results to be affected by the residual effect of the high-voltage test, while the time buffer provided by the time relay KT3 can eliminate this effect, thus improving the accuracy of the low-voltage test.

[0044] In one embodiment, referring to Figure 3 As shown, when the preset time of the time relay KT3 arrives, the normally open contact KT30 of the time relay KT3 closes. At this time, the intermediate relay KM3 and the time relay KT2 are energized. The normally open contacts KM30 and KM31 of the intermediate relay KM3 close simultaneously, and the normally closed contacts KM32 and KM33 of the intermediate relay KM3 open simultaneously, so that the low-voltage tester 20 is connected and performs a low-voltage test on the electronic atomizer through the connector 40.

[0045] Specifically, the precise time control of the time relay KT3 ensures that after the high-voltage test is completed, there is a sufficient time interval (i.e., the preset time, for example: 0.2 - 1 second) before the low-voltage test is carried out. This avoids interference between tests and ensures the independence and accuracy of the tests. Through the control of the time relay KT3, the automation of the test process is realized. Once the high-voltage test is completed, the system will automatically enter the low-voltage test stage without manual intervention. Additionally, when the normally open contact KT30 of the time relay KT3 closes, the intermediate relay KM3 is energized, and the change of its contacts prepares for the low-voltage test. The normally open contacts KM30 and KM31 of the intermediate relay KM3 close to connect the power supply or signal lines required by the low-voltage tester 20. At the same time, the normally closed contacts KM32 and KM33 of the intermediate relay KM3 disconnect to cut off the circuit related to the high-voltage test, ensuring the safety and independence of the circuit during the low-voltage test. Additionally, through the change of the contacts of the intermediate relay KM3, the low-voltage tester 20 is connected and connected to the electronic atomizer through the joint connector 40, so that the low-voltage test can be carried out on the electronic atomizer. That is, the normally open contacts KM30 and KM31 of the intermediate relay KM3 close simultaneously, and the normally closed contacts KM32 and KM33 of the intermediate relay KM3 disconnect simultaneously. The low-voltage tester 20 is connected, and the low-voltage test is performed on the electronic atomizer through the joint connector 40; while the normally closed contacts KM32 and KM33 of the intermediate relay KM3 disconnect simultaneously to achieve circuit interlocking. Even if the intermediate relay KM2 is accidentally energized, causing the normally open contacts KM20 and KM21 of the intermediate relay KM2 to close, in the control circuit, since the normally closed contacts KM32 and KM33 of the intermediate relay KM3 are in the disconnected state, the high-voltage and low-voltage circuits can be effectively isolated.

[0046] In one embodiment, referring to Figure 3 As shown, when the time relay KT2 is energized and the set time arrives, the time relay KT2 starts to work. At this time, the normally closed contact KT20 of the time relay KT2 disconnects, the intermediate relay KM1 disconnects and loses power, and the normally open contacts KM10 and KM11 of the intermediate relay KM1 reset and close simultaneously, and the low-voltage tester 20 is powered off to end the low-voltage test on the electronic atomizer.

[0047] Specifically, the introduction of the time relay KT2 allows for precise control of the duration of the low-voltage test. By presetting the delay time of the time relay KT2 (for example: 0.2 - 1 second), it can ensure that the low-voltage test is completed within a predetermined time period, neither too long nor too short. Once the set time of the time relay KT2 arrives, it will automatically trigger subsequent electrical actions without manual intervention, thus improving the automation level of the test. When the normally closed contact KT20 of the time relay KT2 disconnects, the intermediate relay KM1 will lose power, causing its normally open contacts KM10 and KM11 to reset and disconnect. Importantly, this series of electrical actions will ultimately cause the low-voltage tester 20 to lose power, thus safely ending the test process. By automatically cutting off the power, it can prevent the low-voltage tester 20 from continuing to operate after the test is completed, thereby avoiding potential damage to the electronic atomizer or misreading of the test results. Additionally, the reset and disconnection of the normally open contacts KM10 and KM11 of the intermediate relay KM1 can be used to prepare for subsequent operations of the system or reset the test environment. This design enables the system to flexibly transition from one test stage to another or return to the initial state for the next test. That is, when the time relay KT2 is powered on, it starts to work only when the set time arrives. At this time, the normally closed contact KT20 of the time relay KT2 disconnects, causing the circuit of the intermediate relay KM1 to disconnect and lose power. At this time, the normally open contacts KM10 and KM11 of the intermediate relay KM1 immediately reset and disconnect simultaneously. At this time, the control circuit returns to the initial state to conduct the next product test, repeating the above circuit control and execution.

[0048] This control circuit facilitates the charging test of the electronic atomizer. After the high-voltage DC7.5V test is completed, there is no need to unplug the Type-C connector, nor to insert the Type-C connector of the low-voltage DC5.0V tester again. Instead, it completes the automatic switching through the control circuit. At the same time, an interlock circuit is implemented in the control circuit. When the high-voltage DC7.5V and the low-voltage DC5.V are connected simultaneously, the control circuit is in an open circuit state, protecting the product and the tester from damage. This technology solves the problem that manual operation first tests the protection state of high-voltage DC7.5V at the same station, then unplug the Type-C connector, and then insert the Type-C connector of the low-voltage DC5.0V tester again to test the DC5.0V charging state. That is, adopting this control circuit perfectly solves the problems of missed measurement and frequent plugging and unplugging of the Type-C connector during the test process, improves the test speed, reduces the cost, and increases the efficiency.

[0049] The above embodiments are the preferred implementation schemes of the present utility model. In addition, the present utility model can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present utility model.
