The electronic atomizer is an atomization device driven by a rechargeable lithium polymer battery, and the liquid matrix in a liquid storage tank of the electronic atomizer is atomized into aerosol through the internal atomizer for a user to inhale. The airflow sensor is a key component in the electronic atomizer and is mainly used for controlling the output quantity and the switching state of aerosol. If the user makes an inhalation, the airflow sensor senses and brings the electronic atomizer into an operating state. The airflow sensor adopts an airflow induction switch and mainly comprises a pole piece, a vibrating diaphragm, a gasket, a cavity, a shell, a PCB assembly, an LED and other assemblies. The inventor discovers in the research process that each air flow sensor needs to be tested one by one manually by a tester, so that the testing efficiency is low; therefore, the inventor proposes an airflow sensor detecting device to improve the testing efficiency.

The following embodiments of the present utility model describe an exemplary structure of the airflow sensor detection apparatus 100.

As shown in fig. 1, an airflow sensor detection apparatus 100 is provided. The airflow sensor detection device 100 comprises a device body 1, a positioning component 2, a material pressing component 3, a conductive component 4, a voltage source 5 and a current detection unit 6. The apparatus body 1 includes a carrying table 11. As shown in fig. 2, the positioning assembly 2 is detachably disposed on the carrying platform 11, and has a positioning slot 21, where the positioning slot 21 is used for fixing the airflow sensor. The press assembly 3 is provided to the apparatus body 1, and includes a moving portion 31 (see fig. 6) capable of reciprocating in the first direction Y. The conductive member 4 is mounted on the moving portion 31 and is spaced apart from the positioning member 2 provided on the stage 11 in the first direction Y. The moving portion 31 of the pressing component 3 can drive the conductive component 4 to move to the positioning component 2 disposed on the carrying table 11, so that the conductive component 4 is electrically connected with the air flow sensor disposed in the positioning slot 21. The voltage source 5 is used for providing detection voltage for the air flow sensor, the positive terminal of the voltage source is used for being connected with one power supply pin of the air flow sensor, and the negative terminal of the voltage source is used for being connected with the other power supply pin of the air flow sensor. The current detection unit 6 is disposed on the device body 1, and can form a detection loop with the airflow sensor through the conductive component 4, so as to detect a current flowing through the airflow sensor when the voltage source 5 provides a detection voltage to the airflow sensor.

The device body 1 is a main part of the air flow sensor detection device 100, and serves to physically support and accommodate other components, including the carrying table 11. The carrying table 11 is used for receiving the positioning component 2 and the pressing component 3, and has an operation space for a tester to test in the first direction Y. When the airflow sensor detecting device 100 is placed horizontally, the carrying platform 11 is also disposed horizontally, and the first direction Y is a vertical direction. The positioning groove 21 of the positioning assembly 2 is used for limiting the airflow sensor, so that the position of the airflow sensor is relatively fixed. The pressing component 3 is a component for providing power, and the moving part 31 of the pressing component is provided with the conductive component 4, so that the conductive component 4 can be driven to move to the air flow sensor in the positioning groove 21, and then the pressing component is electrically connected with two leads of the air flow sensor. The voltage source 5 may be a secondary battery such as a storage battery. The current detection unit 6 can be electrically connected to the conductive member 4 to perform circuit detection thereof. The current detection unit 6 may be an ammeter or multimeter, or other means for detecting a circuit. When the circuit detection is completed, the moving part 31 can drive the conductive component 4 to leave the air flow sensor in the positioning groove 21 so as to carry out the detection of the next round. Therefore, the sensor detection device 100 can perform circuit detection for a plurality of cycles, and the detection efficiency can be improved.

In the embodiment of the utility model, the airflow sensor can be tested by adopting an industry standard current stability test mode. The method specifically comprises the following steps: through the above-mentioned air flow sensor detecting device 100, the air flow sensor is carried into the positioning groove 21, and then one of the positive and negative poles of the voltage source 5 outputting a constant voltage is electrically connected with one pin of the air flow sensor, and the other of the positive and negative poles of the voltage source 5 is electrically connected with the other pin of the air flow sensor. The moving part 31 of the pressing assembly 3 drives the conductive assembly 4 to move to the positioning assembly 2 arranged on the carrying table 11, so that the conductive assembly 4 is electrically connected with the air flow sensor in the positioning groove 21. The current detection unit 6 forms a detection loop with the air flow sensor through the conductive component 4, and checks the waveform of the current flowing through the air flow sensor to check the stability of the current. If the current waveform is suddenly jumped up and down, the current waveform indicates that the airflow sensor may be defective. If the current waveform fluctuation is small and the current is stable, the airflow sensor may be good. For example, when the electronic atomizer is an electronic cigarette, the airflow sensor is a microphone, and the airflow sensor detection device 100 provided by the utility model can be used for testing the microphone of the electronic cigarette. In other embodiments, other different types of airflow sensors may also be tested.

Alternatively, the number of positioning slots 21 is between 1 and 20. For example, the number of the positioning grooves 21 is 5, 8, 12, 16, or the like. In the present embodiment, the number of the positioning grooves 21 is 10. In other embodiments, the number of the positioning slots 21 may be set according to actual needs. In this way, the number of air flow sensors that need to be tested without lot can be flexibly adjusted.

As shown in fig. 2, the positioning groove 21 may specifically include a body positioning groove 211 and a lead positioning groove 212 communicating with the body positioning groove 211. The body positioning groove 211 is used for fixing the main body of the airflow sensor, and the lead positioning groove 212 is used for fixing one lead of the airflow sensor. The positioning accuracy of the air flow sensor can be improved by arranging the body positioning groove 211 and the lead positioning groove 212 respectively.

Referring to fig. 1 and 3, the positioning assembly 2 may specifically include a jig plate 22, a jig 23, and a line card 24. The jig plate 22 is detachably disposed on the carrying table 11. The jig 23 is disposed on a side of the jig plate 22 away from the carrying table 11. The line clamp 24 is arranged on one side of the jig 23, which is away from the jig plate 22, and the line clamp 24 and the jig 23 are positioned on the same plane. The body positioning grooves 211 are uniformly spaced along the length direction of the jig 22, the lead positioning grooves 212 are uniformly spaced along the length direction of the line card 24, and the body positioning grooves 211 and the lead positioning grooves 212 are mutually communicated, so that one lead of the air flow sensor can extend from the body positioning grooves 211 to the lead positioning grooves 212. The jig plate 22, the jig 23 and the line clip 24 are respectively arranged to facilitate the assembly and disassembly of the positioning assembly 2.

In combination with fig. 2 and 3, the positioning assembly 2 may optionally further comprise a number plate 25. The number plate 25 is disposed on the jig 23 and located on a side of the body positioning slot 211 away from the lead positioning slot 212, and has Arabic numerals 1, 2, 3, 4, 5, etc. disposed thereon. The Arabic numerals set on the number plate 25 correspond to the positions of the body positioning grooves 211 one by one to show the number and serial numbers of the positioning grooves 21. Therefore, the circuit detection device can play a role in prompting a tester to detect the circuit, and reduces the probability of missing or repeated test.

As shown in fig. 1 and 4, the conductive assembly 4 includes a base 41 and a conductive member 42. The base 41 is disposed on a side of the moving portion 31 facing the positioning assembly 2, and the conductive elements 42 are disposed at intervals along a length direction of the base 41, and the length direction is perpendicular to the first direction Y. When the airflow sensor detecting device 100 is placed horizontally, the first direction Y is the vertical direction, and the longitudinal direction of the base 41 is the horizontal direction. Wherein the conductive element 42 can be electrically connected with two pins of the air flow sensor under the driving of the moving part 31. The conductive element 42 can be electrically connected to the current detection unit 6.

Specifically, the conductive element 42 includes a first conductive member 421 and a second conductive member 422. The first conductive member 421 and the second conductive member 422 are disposed at intervals along the width direction of the base 41, the width direction of which is perpendicular to the first direction Y. That is, when the airflow sensor detecting device 100 is placed horizontally, the width direction of the base 41 is the horizontal direction. The first conductive member 421 is driven by the moving portion 31 to be electrically connected to one pin of the airflow sensor. The second conductive member 422 is electrically connected to the other pin of the air flow sensor by the moving portion 31. Wherein, the first conductive member 421 and the second conductive member 422 are disposed through the base 41. Both ends of the first conductive member 421 are located at both sides of the base 41; both ends of the second conductive member 422 are located at both sides of the base 41. The first conductive member 421 can be electrically connected to one of the pins of the airflow sensor, and the second conductive member 422 can be electrically connected to the other pin of the airflow sensor. The first conductive member 421 can be electrically connected to one of the positive and negative electrodes of the voltage source, and the second conductive member 422 can be electrically connected to the other of the positive and negative electrodes of the voltage source. Accordingly, the voltage source 5, the first conductive member 421, the second conductive member 422, and two pins in the air flow sensor form a detection loop, and thus the current detection unit 6 can detect whether the current of the circuit is abnormal.

As shown in fig. 4, further, the first conductive member 421 may include a conductive probe, and the second conductive member 422 may include a flexible conductive medium 4221 and a metal rod 4222. The metal rod 4222 is inserted through the base 41, and the flexible conductive medium 4221 is connected to one end of the metal rod 4222 facing the positioning assembly 2. In other words, the flexible conductive medium 4221 of the conductive assembly 4 is directly electrically connected to the lead wire retained in the lead wire positioning groove 212, and the flexible conductive medium 4221 is electrically connected to the metal rod 4222. In this way, one of the positive electrode or the negative electrode of the voltage source 5 is electrically connected with the first conductive member 421 and the shorter one of the leads, and the other one of the positive electrode or the negative electrode of the voltage source 5 is electrically connected with the lead limited in the lead positioning groove 212 through the metal rod 4222 and the flexible conductive medium 4221 to form a closed loop, so that whether the current of the circuit is abnormal or not can be detected by the current detecting unit 6. Because the lead wire arrangement positions and lengths of different types of air flow sensors are different, for example, in the embodiment of the utility model, the air flow sensor includes three lead wires, wherein two lead wires have shorter lengths and are limited in the body positioning groove 211, and the other longer lead wire is limited in the lead positioning groove 212. The first conductive member 421 is a conductive probe for electrically connecting to one of two shorter leads. For example, in the present embodiment, one of the two shorter leads located in the body positioning groove 211 exposes only one end of the stub, and the area that can be contacted is very limited, so that when the first conductive member 421 for electrical connection therewith is provided as a conductive probe, connection accuracy can be improved. The flexible conductive medium 4221 in the second conductive member 422 is used for electrically connecting with another wire limited in the wire positioning groove 212. The flexible conductive medium 4221 may be a flexible and electrically conductive material such as an electrically conductive sponge. Due to the flexible characteristic of the flexible conductive medium 4221, the lead wire of the air flow sensor is not deformed due to overlarge acting force when the moving part 31 drives the lead wire of the air flow sensor to move, so that the integrity of the air flow sensor is ensured. In addition, the flexible conductive medium 4221 deforms when it contacts the leads, so that it can wrap the leads of the airflow sensor, avoiding poor contact.

As shown in fig. 2, 3 and 4, further, the number of groups of the conductive members 42 corresponds to the number of positioning grooves 21. Accordingly, the flexible conductive medium 4221 is in one-to-one correspondence with the lead positioning groove 212, and the first conductive member 421 is in one-to-one correspondence with the body positioning groove 211.

As shown in fig. 1 and 5, the airflow sensor detection apparatus 100 may further include a blanking assembly 7. The blanking component 7 is arranged on the device body 1 and is adjacent to the bearing table 11.

The positioning assembly 2 is detachably arranged on the blanking assembly 7, so that the blanking assembly 7 ejects the airflow sensor from the positioning assembly 2.

In conjunction with fig. 1, 2, 3 and 4, in particular, the blanking assembly 7 may include a thimble 71. The ejector pins 71 are arranged at intervals along the length direction of the blanking assembly 7. The number of the ejector pins 71 is identical to the number of the positioning grooves 21. The positions of the ejector pins 71 are in one-to-one correspondence with the positions of the positioning grooves 21. The tester can manually move the jig 23 from the jig plate 22 to the blanking assembly 7, and correspond the body positioning groove 211 in the jig 23 to the position of the thimble 71 above the blanking assembly 7, and the air flow sensor in the body positioning groove 211 corresponds to the thimble 71 one by one and is ejected by the corresponding thimble 71, so that the blanking process is completed. Alternatively, the jig 23, which has been loaded with the air flow sensor, may be placed again on the jig plate 22 for the next round of testing. The ejector pins 71 with the same number as the positioning grooves 21 can finish the blanking of a plurality of air flow sensors at one time, so that the efficiency is improved.

As shown in fig. 6, the press assembly 3 may further include a support frame 32 and a power element 33. The moving part 31 includes a pressing plate 311, a support frame 32 is fixed to the device body 1, and a power element 33 is fixed to the support frame 32. The pressing plate 311 is movably connected with the supporting frame 32 and is driven to move by the power element 33.

Specifically, the power element 33 may include a power body 331 and a movable wall 332. In an embodiment of the present utility model, the power element 33 may include a cylinder, so that the power body 331 corresponds to a body of the cylinder, and the movable wall 332 is connected to a piston rod of the cylinder. In other embodiments, the power element 33 may be any other device capable of providing power.

Alternatively, the number of the pressing plates 311 may be two. One of the pressing plates 311 is disposed on a side of the movable wall 332 facing the conductive member 42, and the other pressing plate 311 is disposed on a side of the pressing plate 311 facing the conductive member 42. The pressing plate 311 disposed at a side of the movable wall 332 facing the conductive member 42 may be configured to directly adhere to the movable wall 332, and the two pressing plates 311 may be connected by a plurality of connection posts. The conductive element 42 is disposed on a side of the platen 311 facing away from the movable arm 322 toward the positioning assembly 2. In the present embodiment, the power element 33 is a cylinder, and if an outsourced cylinder is used, the length of the piston rod is fixed. The two pressing plates 311 are arranged and connected by a plurality of connecting columns, so that the problem that the piston rod is not long enough can be solved. Furthermore, the piston rod of the cylinder is formed of a metallic material, which is disadvantageous for fixing the conductive member 42 thereto, while the two pressing plates 311 may be formed of a non-metallic material, which is advantageous for fixing the conductive member 42 thereto.

Alternatively, one of the two pressing plates 311 adjacent to the positioning assembly 2 may be provided movably connected to the support frame 32, and the other pressing plate 311 is connected only to the movable arm 332. One of the pressing plates 311 is movably connected with the supporting frame 32 to further limit the movement of the pressing plate in the first direction Y.

In summary, by disposing the positioning component 2 and the pressing component 3 on the airflow sensor detecting device 100, the positioning component 2 has a positioning slot 21 for fixing the airflow sensor, and the pressing component 3 can drive the conductive component 4 disposed thereon to move to the positioning component 2, so as to electrically connect the conductive component 4 with the airflow sensor disposed in the positioning slot 21. The air flow sensor detecting apparatus 100 can thus rapidly detect the current flowing through the air flow sensor when the voltage source 5 supplies the detection voltage to the air flow sensor, improving the detection efficiency of the air flow sensor.

The foregoing description is only illustrative of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structures or equivalent processes or direct or indirect application in other related technical fields are included in the scope of the present utility model.
