DETAILED DESCRIPTION
[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0023] The term "and / or" in this document merely describes an association relationship of associated objects, and indicates that there can be three relationships, for example, A and / or B can represent three cases of A alone, A and B together, and B alone. In addition, the character " / " in this document generally represents an "or" relationship between the front and rear associated objects. In addition, "multiple" in this document represents two or more than two.
[0024] In the description of the present application, it should be noted that, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood in a broad sense, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances. In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.
[0025] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as there is no conflict.
[0026] In the related art, the double oil cup electronic atomizer needs to be tested for functions in the production process, such as double oil cup suction resistance test, double oil cup smoke presence test, double oil cup smoke concentration test, and double oil cup suction resistance difference comparison test.
[0027] For example, in the suction resistance test process of the double oil cup electronic atomizer, the suction resistance of both oil cups of the electronic atomizer needs to be tested. The suction resistance test process in the related art includes: first, connecting one oil cup of the electronic atomizer to the test equipment to test the suction resistance value, then switching the oil cup to connect the other oil cup of the electronic atomizer to the test equipment to test the suction resistance value, and finally comparing the two different suction resistance values of the same electronic atomizer to determine whether the difference between the two suction resistance values is less than a preset threshold. If the difference between the two suction resistance values is less than or equal to the preset threshold, the suction resistance of the electronic atomizer meets the quality requirements. If the difference between the two suction resistance values is greater than the preset threshold, the suction resistance of the electronic atomizer does not meet the quality requirements.
[0028] From the above suction resistance test process, it can be seen that since the suction resistance values of the two different oil cups of the electronic atomizer need to be compared, the test process of the two oil cups must be correct. That is, the same oil cup cannot be tested twice or missed. Once the test process is wrong, it will lead to inaccurate test data and numerical comparison program confusion. For example, in the process of testing the suction resistance of multiple electronic atomizers (including electronic atomizers A and B), if the same oil cup is tested twice or missed, it may lead to process confusion, so that the test equipment compares the suction resistance value of one oil cup of electronic atomizer A with the suction resistance value of one oil cup of electronic atomizer B, and thus leads to inaccurate test data and numerical comparison program confusion of the entire test line.
[0029] As can be seen, in the related art, it is easy to occur that one oil cup of the electronic atomizer is not tested or repeatedly tested, thereby leading to inaccurate test data and numerical comparison program confusion.
[0030] To avoid the above problems, some embodiments of the present application provide a test fixture to avoid the test process error in the related art.
[0031] Some embodiments of the present application provide a test fixture for placing an electronic atomizer and sensing the movement of the electronic atomizer to avoid test process errors of the electronic atomizer. Figure 1 is a perspective structural schematic diagram of the test fixture in some embodiments of the present application. Figure 2 is a perspective structural schematic diagram of an electronic atomizer in some embodiments of the present application. As Figure 1 and Figure 2As shown, the test fixture 1 comprises a base 12, a first photoelectric sensor assembly 13 and a second photoelectric sensor assembly 14. The electronic atomizer 2 comprises a main body 22 and a mouthpiece 21 rotatably mounted on the main body 22. The main body 22 has at least two oil cups (not shown) inside for storing atomization medium, which are independent of each other. The main body 22 can be rotated to make different oil cups communicate with the mouthpiece 21, so that the atomization medium in different oil cups is evaporated to be inhaled by a user. The base 12 is used to place the electronic atomizer 2 thereon by holding the mouthpiece 21. Since the mouthpiece 21 is limited by the base 12 and cannot rotate freely, the main body 22 can rotate relative to the mouthpiece 21 to realize switching of different oil cups. The first photoelectric sensor assembly 13 is arranged on the base 12 and is used to emit a first emission light and receive a first reflection light which is reflected by the first emission light on a first part surface of the electronic atomizer 2. The second photoelectric sensor assembly 14 is arranged on the base 12 and is used to emit a second emission light and receive a second reflection light which is reflected by the second emission light on a second part surface of the electronic atomizer 2. The electronic atomizer 2 has a plurality of surfaces, and the first part surface and the second part surface are both part surfaces of the plurality of surfaces of the electronic atomizer 2, and the first part surface is not completely the same as the second part surface; that is, not all circumferential surfaces of the electronic atomizer 2 can reflect the emission light of the photoelectric sensor assembly towards the photoelectric sensor assembly, so that the photoelectric sensor assembly can only receive the reflection light formed by the emission light reflected on the part surface of the electronic atomizer 2. The optical axis of the first emission light and the optical axis of the second emission light are intersected on the base 12. The optical axis of the first emission light is the central axis of the first emission light, and the optical axis of the second emission light is the central axis of the second emission light.
[0032] When the distance between the position irradiated by the first emission light and the first photoelectric sensor assembly 13 is different, the first reflection light can have different properties, thereby forming different signals in the first photoelectric sensor assembly 13. Therefore, when the distance between the position irradiated by the first emission light on the first part surface of the electronic atomizer 2 and the first photoelectric sensor assembly 13 is different, different signals are formed in the first photoelectric sensor assembly 13. When the distance between the position irradiated by the first emission light on the first part surface of the electronic atomizer 2 and the first photoelectric sensor assembly 13 is the same, the same signal is formed in the first photoelectric sensor assembly 13. It can be understood that when the electronic atomizer 2 is not placed on the base 12, the first photoelectric sensor assembly 13 does not receive the first reflection light, and a signal different from that formed when the first reflection light is received is formed in the first photoelectric sensor assembly 13.
[0033] The sensing principle of the second photoelectric sensor assembly 14 is similar to that of the first photoelectric sensor assembly 13, which will not be described herein.
[0034] The test fixture 1 in some embodiments of the present application includes a first photoelectric sensor assembly 13 and a second photoelectric sensor assembly 14 arranged on the base 12. The first photoelectric sensor assembly 13 and the second photoelectric sensor assembly 14 are arranged at different positions on the base 12, and the projections of the optical axes of the first emitted light and the second emitted light on the base 12 intersect, so that the first photoelectric sensor assembly 13 and the second photoelectric sensor assembly 14 can sense different surfaces of the electronic atomizer 2. The two photoelectric sensor assemblies work together to accurately sense the motion state of the electronic atomizer 2. Whether the electronic atomizer 2 is placed on the base 12 or not, or whether the electronic atomizer 2 rotates on the base 12 or not, the first photoelectric sensor assembly 13 and the second photoelectric sensor assembly 14 can generate different signals according to various motion states of the electronic atomizer 2. Therefore, during the test of the electronic atomizer 2, the first photoelectric sensor assembly 13 and the second photoelectric sensor assembly 14 in some embodiments of the present application can be used to determine whether the motion of the electronic atomizer 2 meets the test procedure, thereby reducing the phenomenon of false test, missed test and data comparison confusion of the electronic atomizer 2, and further improving the test efficiency and reducing the test cost.
[0035] Continuing to refer to Figure 1 and Figure 2 In some embodiments, the optical axis of the first emitted light and the optical axis of the second emitted light are perpendicular, so that the first emitted light and the second emitted light can irradiate on two mutually perpendicular surfaces of the electronic atomizer 2. In other embodiments, the optical axis of the first emitted light and the optical axis of the second emitted light can also not be coplanar or perpendicular, and can be adjusted according to the shape of the actual product, so that the first photoelectric sensor assembly 13 and the second photoelectric sensor assembly 14 of the present application can be used to detect atomizers of various shapes.
[0036] In some embodiments, the first photoelectric sensor assembly 13 includes a first bracket 131 and a first photoelectric sensor 132 arranged on the first bracket 131. The first photoelectric sensor 132 has a first emitting element and a first receiving element, the first emitting element is used to emit the first emitted light, and the first receiving element is used to receive the first reflected light.

The second photoelectric sensor 142 has a second emitting element and a second receiving element, the second emitting element is used to emit the second emitted light, and the second receiving element is used to receive the second reflected light.
[0037] In some embodiments, the first photoelectric sensor 132 and the second photoelectric sensor are reflective optical fiber sensors.
[0038] In some embodiments, a first through slot 1311 is formed on the first support 131, and a first photoelectric sensor 132 passes through the first through slot 1311. The first photoelectric sensor 132 can move within the first through slot 1311 in a direction perpendicular to the first optical axis to adjust its position. In some embodiments, the extending direction of the first through slot 1311 can be away from or close to the base 12, so that the position of the first photoelectric sensor 132 can be adjusted in the direction away from or close to the base 12, thereby adjusting the position of the first emitted light illuminating the electronic atomizer 2. In other embodiments, depending on the shape characteristics of the electronic atomizer 2, the first through slot 1311 can extend in other directions, so that the first photoelectric sensor 132 can be set at various positions on the first support 131, so that the first emitted light can illuminate the desired position.
[0039] In some embodiments, a second through slot 1411 is formed on the second bracket 141, and a second photoelectric sensor 142 passes through the second through slot 1411. The second photoelectric sensor 142 can move within the second through slot 1411 in a direction perpendicular to the second optical axis to adjust its position. In some embodiments, the extension direction of the second through slot 1411 can be away from or close to the base 12, so that the position of the second photoelectric sensor 142 can be adjusted in the direction away from or close to the base 12, thereby adjusting the position of the second emitted light illuminating the electronic atomizer 2. In other embodiments, depending on the shape characteristics of the electronic atomizer 2, the second through slot 1411 can extend in other directions, so that the second photoelectric sensor 142 can be set at various positions on the second bracket 141, so that the second emitted light can illuminate the desired position.
[0040] In some embodiments, the first photoelectric sensor assembly 13 includes two first nuts 133. The first photoelectric sensor 132 has a first thread (not shown), which is disposed on both sides of the first through groove 1311. The two first nuts 133 are respectively disposed on both sides of the first through groove 1311 and on the first thread, so that the two first nuts 133 clamp the first bracket 131 to fix the position of the first photoelectric sensor 132. In other embodiments, the first photoelectric sensor 132 can be fixed by a magnetic element, or the first photoelectric sensor 132 can be fixed in the first through groove 1311 by an interference fit. This application does not limit the method of fixing the first photoelectric sensor 132.
[0041] In some embodiments, the second photoelectric sensor assembly 14 includes two second nuts 143, and the second photoelectric sensor 142 is provided with second threads (not shown) arranged on both sides of the second through slot 1411, and the two second nuts 143 are arranged on both sides of the second through slot 1411 and arranged on the second threads, so that the two second nuts 143 clamp the second support 141 to fix the position of the second photoelectric sensor 142. In other embodiments, the second photoelectric sensor 142 can be fixed by a magnetic element, or the second photoelectric sensor 142 can be fixed in the second through slot 1411 by interference fit, and the application does not limit the way of fixing the second photoelectric sensor 142.
[0042] Continuing to refer to Figure 1 and Figure 2 In some embodiments, the base 12 includes a support seat 121 and an operation table 122. The support seat 121 includes a first surface 1211, a second surface 1212, a third surface 1213 and a fourth surface 1214. The first surface 1211 and the second surface 1212 are oppositely arranged, and the third surface 1213 and the fourth surface 1214 are both connected with the first surface 1211. The operation table 122 is arranged on the first surface 1211 of the support seat 121. In some embodiments, the operation table 122 includes a test area 1221, and the test area 1221 is provided with a test slot 1222 to receive the mouthpiece part 21 of the electronic atomizer 2, so that the electronic atomizer 2 can be stably placed on the operation table 122. In other embodiments, the operation table 122 is detachably connected with the support seat 121, so that the operation table 122 with different shapes of test area 1221 can be arranged on the support seat 121, so that the test fixture 1 of the application can test the electronic atomizer 2 with different shapes of mouthpiece.
[0043] In some embodiments, the first support 131 is connected with the third surface 1213 of the support seat 121, and the distance between any position of the first through slot 1311 and the first surface 1211 is greater than the distance between any position of the operation table 122 and the first surface 1211. That is, the position of the first through slot 1311 is higher than the position of the operation table 122, so that the first emission light emitted by the first photoelectric sensor 132 arranged in the first through slot 1311 can irradiate the electronic atomizer 2 placed on the operation table 122, and then the first photoelectric sensor 132 can receive the first reflected light for detecting the motion state of the electronic atomizer 2.
[0044] In some embodiments, the second support 141 is connected to the fourth surface 1214 of the support base 121, and the distance between any position of the second through slot 1411 and the first surface 1211 is greater than the distance between any position of the operation platform 122 and the first surface 1211. That is, the position of the second through slot 1411 is higher than the position of the operation platform 122, so that the first emission light emitted by the second photoelectric sensor 142 arranged in the second through slot 1411 can irradiate the electronic atomizer 2 placed on the operation platform 122, and then the second photoelectric sensor 142 can receive the second reflected light for detecting the motion state of the electronic atomizer 2.
[0045] In some embodiments, the test fixture 1 comprises a support leg 15 arranged on the second surface 1212 of the support base 121. The support leg 15 is used to support the support base 121 and adjust the height of the test fixture 1, so that electronic atomizers 2 with different sizes can be placed on the test fixture 1 for testing.
[0046] Some embodiments of the present application provide a test system, which comprises the test fixture 1 mentioned above and a control system (not shown). The control system is electrically connected to the first photoelectric sensor assembly 13 and the second photoelectric sensor assembly 14 to determine whether the motion of the electronic atomizer 2 conforms to the test procedure. When the motion of the electronic atomizer 2 does not conform to the test procedure, the control system stops the test and issues a prompt and / or an alarm.
[0047] Figure 3 is a perspective structural schematic view of the electronic atomizer in some embodiments of the present application testing the first oil cup on the test fixture, Figure 4 is a perspective structural schematic view of the electronic atomizer in some embodiments of the present application rotating 90° during the process of testing on the test fixture, Figure 5 is a perspective structural schematic view of the electronic atomizer in some embodiments of the present application testing the second oil cup on the test fixture. In order to more clearly describe how the test fixture of the present application reduces the false test and missed test of the electronic atomizer during use, some embodiments of the test procedure of the first oil cup and the second oil cup of the electronic atomizer are described below in combination with Figures 3 to 5
[0048] Step S1: The operator inserts the suction nozzle part 21 of the electronic atomizer 2 into the test slot 1222, and presses the test key to instruct the control system to test the suction resistance value of the first oil cup in communication with the suction nozzle part 21.
[0049] As Figure 3 As shown, during the test, the main body 22 of the electronic atomizer 2 is exposed outside, and the main body 22 includes a first main body surface 221, a second main body surface 222, and a third main body surface 223. The second main body surface 222 and the third main body surface 223 are symmetrical relative to the central axis of the main body 22. The first photoelectric sensor 132 emits first emitted light rays that form a first light spot P1 on the first main body surface 221. The first photoelectric sensor 132 receives first reflected light rays, converts the first reflected light rays into a first signal, and transmits the first signal to the control system. The second photoelectric sensor 142 emits second emitted light rays that form a second light spot P2 on the second main body surface 222, and the distance between the second light spot P2 and the second photoelectric sensor 142 is a first distance L1. The second photoelectric sensor 142 receives second reflected light rays, converts the second reflected light rays into a second signal, and transmits the second signal to the control system.
[0050] After the first oil cup test is completed, if the control system detects that the first signal does not change and the operator continues to instruct the control system to test the suction resistance value of the first oil cup in communication with the suction nozzle part 21 by pressing the test key, the control system stops the test and alarms. That is, the first photoelectric sensor 132 can be used to prevent the tested oil cup from continuing to test.
[0051] After the first oil cup test is completed, if the first signal does not change within a preset time period, the control system alarms and prompts to rotate the main body 22. That is, the first photoelectric sensor 132 can be used to prompt the operator to rotate the main body 22 to continue testing the untested oil cup.
[0052] After the first oil cup test is completed, if the operator takes out the electronic atomizer 2, the second emitted light rays cannot irradiate the main body 22, and at this time the second photoelectric sensor 142 transmits a zero signal to the control system. Therefore, after the first oil cup test is completed, if the signal received by the control system changes from the second signal to the continuous zero signal, the control system stops the detection and alarms. That is, the second photoelectric sensor 142 can be used to prevent the electronic atomizer 2 from being taken out without completing all the tests.
[0053] Step S2: After the suction resistance value test of the first oil cup is completed, the operator rotates the main body 22 by 180° along the central axis of the main body 22 to make the second oil cup in communication with the suction nozzle part 21, and instructs the control system to test the suction resistance value of the second oil cup by pressing the test key.
[0054] During the rotation of the main body 22 by 180°, the distance between the second light spot P2 and the second photoelectric sensor 142 changes. As shown, when the main body 22 is rotated by 90°, the second light spot P2 is on the first main body surface 221, and thus the distance between the second light spot P2 and the second photoelectric sensor 142 is a second distance L2. As shown, when the main body 22 is rotated by 180°, the second light spot P2 is on the third main body surface 223, and thus the distance between the second light spot P2 and the second photoelectric sensor 142 is a third distance L3. Figure 4 Figure 5 As shown, when the main body 22 is rotated by 180°, the second light spot P2 is on the third main body surface 223. Since the second main body surface 222 and the third main body surface 223 are symmetrical relative to the central axis of the main body 22, the distance between the second light spot P2 and the second photoelectric sensor 142 returns to L1. Therefore, during the rotation of the main body 22 by 180°, the signal received by the control system changes from the second signal to the other signal, and then changes from the other signal to the second signal. At this time, the test procedure is correct, and the control system can continue to test the suction resistance value of the second oil cup.
[0055] Step S3: After the suction resistance value test of the second oil cup is completed, the test system compares the difference between the two suction resistance values of the electronic atomizer 2.
[0056] It can be understood that, once the missing test or the false test occurs in the above test process, in the process of testing multiple electronic atomizers, the test system will compare the suction resistance values of the oil cups of two different electronic atomizers, thereby causing confusion in the data comparison of the entire production line. Therefore, the test fixture of the present application can reduce the phenomenon of confusion in the data comparison.
