Then, the hydraulic cylinder 10 at the bottom end of the convex extension seat 6 is started to drive the detection cover 2 to move downward, so that the detection cover 2 is adapted to be connected with the hearing aid device 3 fixed in the positioning groove, simulating the state of the hearing aid device 3 after the shell is packaged. Then, the pressure pump in the water storage tank 7 is started, and water is pressed into the pressure outer frame 8 through a hose, and sprayed out through multiple atomizing nozzles 9, so that the hearing aid device 3 is in a water mist, simulating the humid environment in which the hearing aid device 3 is used in daily use. Then, the negative pressure air pump 26 is started to gradually extract the air in the space between the hearing aid device 3 and the detection cover 2, so that the space is in a negative pressure state, thereby facilitating the external humid air to penetrate and dissipate faster into the hearing aid device 3. In this process, the conductive test of the circuit board in the hearing aid device 3 is continuously performed through the resistance guide rod 11, and the circuit changes of the entire circuit board are recorded; The above advantages are as follows: in this way, multiple atomizing nozzles 9 can be used to simulate the humid environment of daily use of the hearing aid device 3, and then the negative pressure state in the hearing aid device 3 can be used to allow the external humid air to quickly penetrate and diffuse into the inside, so as to simulate in a short time the state of the circuit board in the hearing aid device 3 being damp after long-term use, so as to facilitate dynamic real-time detection in the process of the circuit board gradually being damp, and quickly detect the moisture-proof performance of the circuit board in the hearing aid device 3; The inner end surface of the detection cover 2 is connected to a plurality of abutment guide rods 11, and both sides of the abutment guide rods 11 are provided with measuring and pulling telescopic rods 22, and the outer side wall of the fixed end of the measuring and pulling telescopic rods 22 is connected to a photoelectric sensor 25, and a pull wire assembly is provided below the photoelectric sensor 25; Furthermore, the bottom end of the convex top seat 6 is fixedly connected to the top end of the detection cover 2 through the hydraulic cylinder 10, a test power supply is provided in the detection cover 2 and is electrically connected to a plurality of abutment guide rods 11, the wire drawing assembly is composed of an arc seat 23 and two wire drawing rods 24, the inner end surface of the detection cover 2 is fixedly connected to the top end of the arc seat 23 through a measuring and pulling telescopic rod 22, and the two side walls of the arc seat 23 are respectively slidably connected to the two wire drawing rods 24, and the wire drawing rods 24 are hydraulic push rod structures; It should be noted that: after the detection cover 2 moves down and docks, the two drawing rods 24 in the arc surface seat 23 will be controlled to be hydraulically pushed outward, so that the drawing rods 24 extend under the welding circuits in front and behind the circuit board in the hearing aid device 3. When the detection cover 2 is separated and moved up later, the detection cover 2 will be controlled to move up at a slow speed, and the welding circuits in front and behind the circuit board in the hearing aid device 3 will be gradually pulled by the drawing rods 24. If the welding circuit is qualified, the distance between the through-beam photoelectric sensor 25 on the telescopic rod 22 to be tested and the arc surface seat 23 remains unchanged in a short time, and the drawing rod 24 will be controlled to be quickly retracted. If the welding circuit is unqualified and breaks or falls off during the pulling process, the distance between the through-beam photoelectric sensor 25 and the arc surface seat 23 will instantly become smaller, thereby being detected and transmitting a signal, indicating that the welding circuit is unqualified. Based on the above advantages, the through-beam photoelectric sensor 25 can be used to measure the distance change from the arc seat 23, and the strength of the welding line between the circuit board and other devices in the narrow space of the hearing aid device 3 can be understood, thereby ensuring the quality of the hearing aid produced; The inner end surface of the detection cover 2 located directly above the sound receiving unit 4 and the sound amplifying unit 5 is fixedly connected with a probe column 12, and the outer wall of the probe column 12 is slidably connected with an electromagnetic moving ring 13, and the bottom end of the electromagnetic moving ring 13 is connected to a retaining magnetic ring 15 through a reset spring 14, and the bottom end of the retaining magnetic ring 15 is respectively connected to a plurality of sealing components for isolating the sound receiving unit 4 and the sound amplifying unit 5 through a plurality of steering pin shafts 16; Furthermore, the inner end surface of the detection cover 2 is fixedly connected to the top of the probe column 12, the bottom end of the electromagnetic moving ring 13 is fixedly connected to the top of the fixed magnetic ring 15 through the reset spring 14, the sealing assembly is composed of an arc plate 17 and a spherical cover 18, the bottom end of the fixed magnetic ring 15 is rotatably connected to the top of the arc plate 17 through the steering pin 16, the bottom end of the arc plate 17 is fixedly connected to the top of the spherical cover 18, a torsion spring is arranged on the outer side wall of the end of the steering pin 16, a plurality of compensation traction rods 19 are rotatably connected to the bottom end of the electromagnetic moving ring 13, a compensation groove is arranged on the outer side wall of the arc plate 17, the inner side wall of the outer end of the compensation groove is rotatably connected to the bottom end of the compensation traction rod 19, the spherical cover 18 is made of rubber, and a sound insulation material is arranged on the inner side wall of the spherical cover 18, the bottom end of the probe column 12 located above the sound receiving unit 4 is fixedly connected to a loudspeaker 20, the bottom end of the probe column 12 located above the sound amplification unit 5 is fixedly connected to a micro decibel meter 21, and the top end of the detection cover 2 is fixedly connected to a negative pressure air pump 26; It should be noted that: when the detection cover 2 moves downward after docking, the electromagnetic moving ring 13 will be energized, so that the bottom end of the electromagnetic moving ring 13 and the top end of the retaining magnetic ring 15 have opposite magnetic poles, and the electromagnetic moving ring 13 will move downward due to the magnetic attraction force. The downward movement of the electromagnetic moving ring 13 will drive multiple compensation traction rods 19 to move downward together, and the bottom end of the compensation traction rod 19 will push the arc plate 17 obliquely downward, so that the multiple arc plates 17 rotate downward through the steering pin shaft 16, and then drive the multiple spherical covers 18 to rotate and gather together, so that the sound receiving unit 4 and the sound amplifying unit 5 in the hearing aid device 3 are in a relatively independent sealed state, and then the speaker 20 in the sealed space where the sound receiving unit 4 is located emits normal sound and noise without frequency regularity respectively, and the sound changes detected by the micro decibel meter 21 in the sealed space where the sound amplifying unit 5 is located are observed, so as to know whether the function of the noise reduction chip on the circuit board in the hearing aid device 3 is affected during the above detection process; The above advantages are as follows: by utilizing the convergence of the multiple spherical covers 18, the sound receiving unit 4 and the sound amplifying unit 5 in the hearing aid device 3 can be in an independently sealed state, thereby avoiding mutual influence during the close-range detection process, and detecting whether the noise reduction function of the hearing aid device 3 is damaged during the detection process according to the comparison changes of different sound reception and transmission; When the present invention is in use, the internal space of the hearing aid device 3 to be tested is placed upward in the positioning groove on the testing seat 1, and the various components in the hearing aid device 3 are placed upward to facilitate subsequent testing. Then, the hydraulic cylinder 10 at the bottom end of the convex extension seat 6 is started to drive the detection cover 2 to move downward, so that the detection cover 2 is adapted to be docked with the hearing aid device 3 fixed in the positioning groove (air can enter the gap after docking), simulating the state of the hearing aid device 3 after the shell is packaged. Then, the pressure pump in the water storage tank 7 is started to pressurize water into the pressure outer frame 8 through a hose and spray it out through multiple atomizing nozzles 9, so that the hearing aid device 3 is in a water mist, simulating the humid environment in which the hearing aid device 3 is in daily use. Then, the negative pressure air pump 26 is started to gradually extract the air in the space between the hearing aid device 3 and the detection cover 2, so that the space is in a negative pressure state, thereby facilitating external testing. The humid air outside the hearing aid device 3 penetrates and dissipates faster into the hearing aid device 3. During this process, the conductive test of the circuit board in the hearing aid device 3 is continuously performed through the resistance guide rod 11, and the circuit changes of the entire circuit board are recorded. This is a prior art and will not be described in detail here. In this way, multiple atomizing nozzles 9 can be used to simulate the humid environment of daily use of the hearing aid device 3, and then the negative pressure state in the hearing aid device 3 is used to allow the external humid air to quickly penetrate and diffuse into the interior, so as to simulate the state of the circuit board in the hearing aid device 3 being damp after long-term use in a short time. According to the changes in the circuit during the inspection process, it is convenient to perform dynamic real-time detection in the process of the circuit board gradually being damp, and quickly detect the moisture-proof performance of the circuit board in the hearing aid device 3 (the circuit board in the hearing aid is usually treated with moisture-proof treatment, and this is to detect the moisture-proof performance of the circuit board after moisture-proof treatment); After the detection cover 2 moves down and docks, the two drawing rods 24 in the arc seat 23 are controlled to be hydraulically pushed outward, so that the drawing rods 24 extend under the welding lines in front and behind the circuit board in the hearing aid device 3. When the detection cover 2 is separated and moved up later, the detection cover 2 is controlled to move up at a slow speed, and the welding lines in front and behind the circuit board in the hearing aid device 3 are gradually pulled by the drawing rods 24. If the welding lines are qualified, the distance between the measured distance between the photoelectric sensor 25 and the arc seat 23 to be tested remains unchanged in a short time, and the drawing rods 24 are controlled to be quickly retracted. If the welding lines are unqualified and break or fall off during the pulling process, the distance between the photoelectric sensor 25 and the arc seat 23 will instantly become smaller, which is detected and a signal is transmitted, indicating that the welding lines are unqualified. In this way, the distance change between the photoelectric sensor 25 and the arc seat 23 can be measured by the photoelectric sensor 25, and the strength of the welding lines between the circuit board and other devices in the narrow space of the hearing aid device 3 can be understood, thereby ensuring the quality of the produced hearing aids. When the detection cover 2 moves downward after docking, the electromagnetic moving ring 13 will be energized, so that the bottom end of the electromagnetic moving ring 13 and the top end of the retaining magnetic ring 15 have opposite magnetic poles, and the electromagnetic moving ring 13 will move downward due to the magnetic attraction, and the downward movement of the electromagnetic moving ring 13 will drive the multiple compensation traction rods 19 to move downward together, and the bottom end of the compensation traction rod 19 will push the arc plate 17 obliquely downward, so that the multiple arc plates 17 rotate downward through the steering pin shaft 16, and then drive the multiple spherical covers 18 to rotate and gather together, so that the sound receiving unit 4 and the sound amplifying unit 5 in the hearing aid device 3 are in a relatively independent sealed state, and then the sound receiving unit 4 is in the sealed state. The loudspeaker 20 in the space emits normal sound and irregular frequency noise respectively. By observing the sound changes detected by the micro decibel meter 21 in the sealed space where the sound amplifier unit 5 is located, it can be known whether the noise reduction chip function on the circuit board in the hearing aid device 3 is affected during the above-mentioned detection process. In this way, the gathering changes of multiple spherical covers 18 can be utilized to make the sound receiving unit 4 and the sound amplifier unit 5 in the hearing aid device 3 in an independent and sealed state to avoid mutual influence during the close-range detection process. According to the comparative changes of different sound reception and transmission, it is detected whether the noise reduction function of the hearing aid device 3 is damaged during the detection process.
