[0041] Referring to Figure 1 , an embodiment of the present application provides an acoustic detection device with cleaning function, comprising a host 10 and an acoustic detection module 20. The acoustic detection module 20 comprises at least one acoustic detection unit 21.

[0042] Referring to Figure 1 and Figure 2 , the host 10 is provided with a display screen 17, the display screen 17 is in communication connection with the acoustic detection unit 21, and the display screen 17 can display the data collected by the acoustic detection unit 21. Referring to Figure 1 , Figure 2 and Figure 17 , the host 10 is provided with a first accommodating groove 11 on the side away from the display screen 17, and the acoustic detection unit 21 is arranged in the first accommodating groove 11.

[0043] Further, referring to Figure 5 , Figure 20 and Figure 21 , the acoustic detection unit 21 comprises a shell 213 and a microphone 214. The shell 213 is provided with a first jack 21311 and a receiving cavity 21317, the first jack 21311 is in communication with the receiving cavity 21317, and the microphone 214 is arranged in the first jack 21311.

[0044] In use, the acoustic detection device with cleaning function is placed in the environment to be detected, and the sound in the environment to be detected can be picked up by the microphone 214 through the first jack 21311, so that the microphone 214 can capture the acoustic information in the environment to be detected. However, after long-term use of the acoustic detection device with cleaning function, impurities are easily attached to the surface of the microphone 214, thereby affecting the accuracy of the microphone 214 in capturing the sound source.

[0045] Therefore, in one embodiment, the microphone 214 is movably arranged in the first jack 21311, and the microphone 214 can be withdrawn from the first jack 21311 into the receiving cavity 21317.

[0046] Further, referring to Figure 3 , Figure 4 and Figure 20The acoustic detection device with the cleaning function further comprises an air suction mechanism 30 arranged in the main machine 10. Optionally, the air suction mechanism 30 is a gas pump. The air suction mechanism 30 has an air suction port in communication with the accommodating cavity 21317. When the microphone 214 is located in the accommodating cavity 21317, the air suction mechanism 30 can drive external air to enter the accommodating cavity 21317 through the first jack 21311, so as to suck the impurities on the surface of the microphone 214 into the accommodating cavity 21317.

[0047] If it is needed to clean the impurities on the surface of the microphone 214, the microphone 214 is first withdrawn from the first jack 21311 into the accommodating cavity 21317, so that the external air can communicate with the accommodating cavity 21317 through the first jack 21311. Then, the air suction mechanism 30 is started to suck the air in the accommodating cavity 21317, so that a negative pressure is formed in the accommodating cavity 21317. In this way, the external air can enter the accommodating cavity 21317 through the first jack 21311, so as to suck the impurities adhered to the first jack 21311 and the impurities adhered to the surface of the microphone 214 into the accommodating cavity 21317, thereby realizing the cleaning of the first jack 21311 and the microphone 214 and ensuring the precision of the microphone 214 in capturing the sound source. During the whole cleaning process, the high-speed air flow will not be formed to the microphone 214, so that the microphone 214 can be prevented from being damaged in the cleaning process, thereby prolonging the service life of the acoustic detection device with the cleaning function.

[0048] In one embodiment, the acoustic detection device with the cleaning function further comprises a mounting seat arranged in the first accommodating groove 11. The shell 213 is arranged on the mounting seat, and the shell 213 can move towards or away from the mounting seat.

[0049] Further, referring to Figure 16 , the acoustic detection device with the cleaning function further comprises a driving mechanism 40. The driving mechanism 40 is arranged in the mounting seat, the driving mechanism 40 is connected with the shell 213, and the driving mechanism 40 is used to drive the shell 213 to move away from the mounting seat. If it is needed to clean the impurities on the microphone 214, the driving mechanism 40 is started to drive the shell 213 to move away from the mounting seat, so that the microphone 214 is withdrawn from the first jack 21311 into the accommodating cavity 21317.

[0050] Specifically, referring to Figure 16 and Figure 18 , the mounting seat is provided with an avoiding groove 2188, and the driving mechanism 40 is arranged in the avoiding groove 2188. In this way, the avoiding groove 2188 can play an avoiding role for the installation of the driving mechanism 40, so as to avoid the installation of the driving mechanism 40 from being interfered.

[0051] In one embodiment, referring toFigure 20 and Figure 21 The shell 213 includes opposite first and second mounting portions. The first mounting portion is arranged away from the mounting seat and is provided with a first insertion hole 21311. The second mounting portion is attached to the mounting seat and is provided with a first sliding hole 21315 in communication with a receiving cavity 21317. The first sliding hole 21315 is arranged opposite to the first insertion hole 21311.

[0052] Further, referring to Figure 5 and Figure 20 The acoustic detection unit 21 further includes a first support 216 which is in the shape of a shaft or a rod. A first end of the first support 216 is connected to the microphone 214, and a second end of the first support 216 passes through the first sliding hole 21315 and is connected to the mounting seat. Specifically, the second end of the first support 216 is in sealing engagement with the hole wall of the first sliding hole 21315.

[0053] By arranging the first support 216, the first support 216 can support the microphone 214, and at the same time, the first support 216 can abut against the microphone 214, so that the microphone 214 is stably and reliably arranged in the first insertion hole 21311, the acoustic center of the microphone 214 is always coaxial with the first insertion hole 21311, and the signal capturing accuracy of the sound source is improved.

[0054] In addition, under the action of the first support 216, the movement of the shell 213 is guided, so that the first insertion hole 21311 of the shell 213 is always arranged opposite to the microphone 214, so that the external air entering the receiving cavity 21317 through the first insertion hole 21311 can directly blow the surface of the microphone 214, so that the impurities on the surface of the microphone 214 can be effectively cleaned.

[0055] In one embodiment, referring to Figure 20 and Figure 21 The first insertion hole 21311 is provided in plurality, and the plurality of first insertion holes 21311 are arranged in an array. Referring to Figure 1 The microphone 214 is provided in plurality, and the plurality of microphones 214 are one-to-one correspondingly arranged in the plurality of first insertion holes 21311.

[0056] In one embodiment, referring to Figure 5 and Figure 20 The first mounting portion further includes a first conical sleeve 21313 on the side facing the receiving cavity 21317, the first conical sleeve 21313 is coaxially arranged with the first insertion hole 21311, and the first conical sleeve 21313 is sleeved on the microphone 214.

[0057] Further, referring to Figure 5The first support 216 is provided with a first conical cover 2161. When the microphone 214 is located in the first insertion hole 21311, the first conical cover 2161 is arranged outside the first conical sleeve 21313 and abuts with the first conical sleeve 21313. When the microphone 214 is assembled into the first insertion hole 21311, the first conical cover 2161 is in conical surface cooperation with the first conical sleeve 21313, so as to realize self-centering positioning, ensure that the axis of the microphone 214 is completely coincident with the axis of the first insertion hole 21311, and avoid assembly deviation of the microphone 214. Under the cooperation of the first conical sleeve 21313 and the first conical cover 2161, the microphone 214 can be effectively prevented from loosening or falling off due to vibration, thermal expansion and contraction and the like. In addition, the first conical sleeve 21313 is in close cooperation with the conical surface of the first conical cover 21313, so as to avoid acoustic crosstalk between the plurality of microphones 214 and improve the sound pickup accuracy of the microphone 214.

[0058] In one embodiment, referring to Figure 20 and Figure 21 , the hole wall of the side of the first insertion hole 21311 away from the accommodation cavity 21317 is a conical structure. Specifically, in the direction from inside to outside, the diameter of the side of the first insertion hole 21311 away from the accommodation cavity 21317 gradually increases to form a horn shape. In this way, sound waves can be effectively collected.

[0059] In one embodiment, referring to Figure 20 and Figure 21 , the first mounting portion is further provided with a second insertion hole 21312, and the second insertion hole 21312 is in communication with the accommodation cavity 21317.

[0060] Further, referring to Figure 5 , the acoustic detection unit 21 further includes a camera 215 arranged in the second insertion hole 21312. In this way, the camera 215 can obtain visual image information through the second insertion hole 21312, and the acoustic detection device with cleaning function can improve the detection accuracy by combining the visual image information and the sound source information.

[0061] In one embodiment, the camera 215 is movably arranged in the second insertion hole 21312, and the camera 215 can be withdrawn from the second insertion hole 21312 into the accommodation cavity 21317.

[0062] If the camera 215 needs to be cleaned, the camera 215 is first withdrawn from the second insertion hole 21312 into the accommodating cavity 21317, so that the external air can pass through the second insertion hole 21312 to communicate with the accommodating cavity 21317. Then, the air suction mechanism 30 is started, and the air suction mechanism 30 performs air suction on the accommodating cavity 21317, so that a negative pressure is formed in the accommodating cavity 21317. Thus, the external air can enter the accommodating cavity 21317 through the second insertion hole 21312, so as to suck the impurities attached to the second insertion hole 21312 and the impurities attached to the surface of the camera 215 into the accommodating cavity 21317, thereby achieving cleaning of the second insertion hole 21312 and the camera 215. During the entire cleaning process, the camera 215 is not subjected to high-speed airflow impact, thereby avoiding damage to the camera 215 during cleaning, and being conducive to prolonging the service life of the acoustic detection device with the cleaning function.

Specifically, the second end of the second support 217 is in sealing fit with the hole wall of the second sliding hole 21316.

[0065] By arranging the second support 217, the second support 217 can support the camera 215, and at the same time, the second support 217 can abut against the camera 215, so that the camera 215 is stably and reliably arranged in the second insertion hole 21312, the acoustic center of the camera 215 is always coaxial with the second insertion hole 21312, and the image information capturing accuracy is improved.

[0066] In addition, under the action of the second support 217, the movement of the shell 213 is guided, so that the second insertion hole 21312 of the shell 213 is always arranged opposite to the camera 215. Thus, after the external air enters the accommodating cavity 21317 through the second insertion hole 21312, the surface of the camera 215 can be directly blown, so that the impurities on the surface of the camera 215 can be effectively cleaned.

[0067] In one embodiment, referring to Figure 5 , Figure 20 and Figure 21The first mounting portion is further provided with a second conical sleeve 21314 on the side facing the accommodating cavity 21317.

When the camera 215 is located in the second insertion hole 21312, the second conical cover 2171 is arranged outside the second conical sleeve 21314 and abuts against the second conical sleeve 21314. When the camera 215 is assembled into the second insertion hole 21312, the second conical cover 2171 and the second conical sleeve 21314 form a conical surface cooperation, realizing self-centering positioning, ensuring that the axis of the camera 215 is completely coincident with the axis of the second insertion hole 21312, and avoiding assembly deviation of the camera 215. Under the cooperation of the second conical sleeve 21314 and the second conical cover 2171, the camera 215 can be effectively prevented from loosening or falling off due to vibration, thermal expansion and contraction, etc.

[0069] In one embodiment, referring to Figure 20 and Figure 21 The hole wall of the side of the second insertion hole 21312 facing away from the accommodating cavity 21317 is in a conical structure. Specifically, in the direction from inside to outside, the diameter of the side of the second insertion hole 21312 facing away from the accommodating cavity 21317 gradually increases to form a horn shape. In this way, the field of view of image acquisition of the camera 215 can be expanded.

During the process of moving the shell 213 away from the mounting seat for cleaning, the first elastic member 2163 is gradually compressed. When the cleaning is completed, the external force acting on the shell 213 is removed, the first elastic member 2163 restores the deformation, and drives the shell 213 to move towards the mounting seat to reset, so that the second mounting portion is attached to the mounting seat, the microphone 214 is inserted into the first insertion hole 21311, and the camera 215 is inserted into the second insertion hole 21312.

[0071] Further, referring to Figure 15At least one of the first support 216 and the second support 217 is provided with a compression ring 2162, and a first elastic member 2163 is sleeved on the first support 216 and / or the second support 217, and an end of the first elastic member 2163 away from the shell 213 is connected with the compression ring 2162. In this way, the first support 216 and the second support 217 can guide the expansion and contraction of the first elastic member 2163, and the stability of the expansion and contraction of the first elastic member 2163 is improved.

[0072] In an embodiment, the shell 213 comprises an upper shell and a lower shell. The upper shell and the lower shell are detachably connected. During cleaning, impurities on the surfaces of the microphone 214 and the camera 215 are sucked into the containing cavity 21317. After cleaning is completed, the shell 213 is detached, so that the impurities in the containing cavity 21317 are conveniently cleaned, and the convenience of cleaning the impurities is improved.

In this way, when the shell 213 moves towards or away from the mounting seat, the length of the suction pipe 31 can be adaptively lengthened or shortened, so that the movement of the shell 213 is not interfered, and meanwhile, the suction pipe 31 is prevented from loosening.

[0075] Of course, in other embodiments, the suction pipe 31 can be a telescopic bellows or the like.

[0076] In an embodiment, referring to Figure 3 The acoustic detection device with a cleaning function further comprises a filter 32. The filter 32 is arranged at the end of the suction pipe 31 away from the suction mechanism 30. In this way, the filter 32 can filter the impurities in the containing cavity 21317, so that the impurities are prevented from blocking the suction pipe 31.

[0077] Of course, in other embodiments, the filter 32 can also be arranged at the suction pipe 31. Alternatively, the filter 32 is arranged at the suction port.

[0078] In an embodiment, the acoustic detection module 20 is detachably connected with the host 10. In this way, the acoustic detection module 20 can be taken out of the first accommodating groove 11 to detect the sound source in a narrow space, so that the application range of the acoustic detection device with a cleaning function is expanded.

[0081] In the initial state, at least part of the first acoustic detection unit 211 and at least part of the second acoustic detection unit 212 are arranged in the first accommodating groove 11 and connected with the host 10. In this way, the acoustic detection device with cleaning function in the initial state can detect the sound source in a larger space.

[0082] Since the first acoustic detection unit 211 and the second acoustic detection unit 212 are both detachably connected with the host 10, the first acoustic detection unit 211 and the second acoustic detection unit 212 can be taken out of the first accommodating groove 11, so that the first acoustic detection unit 211 and the second acoustic detection unit 212 are separated from the host 10, so that the first acoustic detection unit 211 and the second acoustic detection unit 212 can extend into a narrow space to detect the sound source in the narrow space.

[0083] Since the area of the first mounting portion of the second shell 2132 is smaller than the area of the first mounting portion of the first shell 2131, and the first acoustic detection unit 211 and the second acoustic detection unit 212 are detachably connected, the second acoustic detection unit 212 can be taken out of the first accommodating groove 11, so that the second acoustic detection unit 212 is separated from the first acoustic detection unit 211, so that the second acoustic detection unit 212 can extend into a more narrow space to detect the sound source in the more narrow space.
