[0035] According to an embodiment of the present application, a waterproof and detachable ultrasonic transducer is provided, which includes a shell 1, a sealing assembly 4, and a connector 5; the shell 1 has a limiting groove 11, in which a ceramic piece 2 and a converter 3 are arranged, one side of the ceramic piece 2 is connected to the shell 1, and the side of the ceramic piece 2 facing away from the shell 1 is connected to the converter 3; the sealing assembly 4 includes a sealing piece 41 and a clamping piece 42, at least part of the sealing piece 41 is embedded in the limiting groove 11, and the sealing piece 41 is provided with a plug-in portion 411 along the axial direction of the shell 1, and the clamping piece 42 is arranged on the plug-in portion 411, and the clamping piece 42 can undergo elastic deformation along the radial direction of the limiting groove 11; one end of the connector 5 is connected to the converter 3, and the end of the connector 5 facing away from the converter 3 passes through the sealing assembly 4.
[0036] like Figures 1 to 4 As shown, the housing 1 is columnar, and a limiting groove 11 is provided along the axial direction of the housing 1. The axial direction of the limiting groove 11 is the same as the axial direction of the housing 1.
[0037] like Figures 2 to 4 As shown, one side of the piezoelectric ceramic sheet 2 is fixed in the limiting groove 11 of the housing 1 through colloid. The other side of the piezoelectric ceramic sheet 2 is connected to the connector 5. The connector 5 is a PCB adapter board. The piezoelectric ceramic sheet 2 can be connected and fixed to the PCB adapter board through an adhesive such as colloid.
[0038] like Figures 1 to 4 As shown, the housing 1 has a limiting groove 11 with an open end. The sealing component 4 is embedded in the opening of the housing 1. The sealing component 4 is connected to the opening of the housing 1 to seal the limiting groove 11 of the housing 1 to prevent external liquid from entering the interior of the housing 1 and damaging the components in the housing 1.
[0039] like Figures 2 to 5 As shown, the sealing assembly 4 includes a sealing member 41. The sealing member 41 is a sealing nut. The sealing member 41 is provided with a plug-in portion 411. The plug-in portion 411 is a plug-in portion 411 opened along the axial direction of the sealing member 41. A part of the sealing member 41 is embedded in the limiting groove 11, and the plug-in portion 411 is connected to the limiting groove 11.
[0040] The seal 41 is connected to the limit groove 11 of the housing 1, and the clamp 42 is embedded in the plug-in portion 411, so that the clamp 42, the seal 41 and the housing 1 are connected to achieve a detachable connection of the transducer. The housing 1, the seal 41 and the locking member 43 are detachably connected to facilitate the maintenance of the device or the replacement of components.
[0041] The sealing assembly 4 may be made of elastic materials, such as a sealing member 41 and a clamping member 42 made of rubber.
[0042] like Figures 2 to 5 As shown, the clamp 42 includes a first elastic portion and a second elastic portion.
[0043] The first elastic part is in the shape of a truncated cone with a larger top and a smaller bottom. The first elastic part is arranged at one end of the plug-in part 411 close to the PCB adapter board.
[0044] The second elastic part is cylindrical, and one end of the second elastic part is connected to the center of the upper surface of the first elastic part. The first elastic part and the second elastic part are integrally formed.
[0045] Of course, in the embodiment of the present application, the housing 1 is not limited to the above structure, and those skilled in the art can configure it according to actual needs. For example, the second elastic part can also be a prism or other structure.
[0046] The clamping member 42 is made of elastic material and can be elastically deformed along the radial direction of the limiting groove 11. The clamping member 42 is embedded in the plug-in portion 411 to cooperate with the sealing member 41 to seal the limiting groove 11, so that the transducer is waterproof.
[0047] like Figures 1 to 4 As shown, the connector 5 is a wire. The wire is made of PVC. One end of the wire extends into the limit groove 11 to connect with the PCB adapter plate, and the other end of the wire passes through the plug-in portion 411 and the clamp 42, extends out of the sealing component 4 to connect with the external device. The clamp 42 can be elastically deformed. Therefore, when the wire passes through the clamp 42, the clamp 42 is elastically deformed along the radial direction of the limit groove 11 to wrap the wire and prevent liquid from entering the inside of the transducer through the gap of the wire.
[0048] The piezoelectric ceramic sheet 2 generates high-frequency vibrations through voltage excitation to emit ultrasonic waves and transmit electrical signals. The electrical signals are connected to the wires through the PCB board and transmitted to the circuit board through the wires to analyze the data.
[0049] like Figures 1 to 4 As shown, the housing 1 is integrally formed of pps material, and has good waterproof performance under hardness protection.
[0050] Of course, in the embodiment of the present application, the housing 1 is not limited to the above structure, and those skilled in the art can configure it according to actual needs.
[0051] In the embodiment of the present application, the sealing member 41 and the clamping member 42 are combined to seal the limit groove 11 to prevent liquid from entering the limit groove 11 and wetting the components in the shell 1, causing an internal short circuit or affecting the performance of the transducer. In addition, the sealing member 41 and the shell 1 are detachably connected to facilitate the inspection or replacement of the components in the limit groove 11.
[0052] In an example, the sealing assembly 4 further includes a locking member 43 , wherein the locking member 43 is embedded in the plug-in portion 411 , and the locking member 43 is sleeved on an end of the clamping member 42 that is away from the adapter 3 .

[0054] The sealing nut has a plug-in portion 411 opened along the circumferential direction. The sealing bolt and the clamp 42 are embedded in the plug-in portion 411. The clamp 42 is embedded in the side of the plug-in portion 411 close to the PCB adapter board, and the sealing bolt is embedded in the side of the plug-in portion 411 away from the PCB adapter board.
[0055] The sealing bolt abuts against the inner wall of the plug-in portion 411. The first elastic portion of the clamp 42 abuts against the inner wall of the plug-in portion 411. The second elastic portion of the clamp 42 is embedded in the sealing bolt, that is, the second elastic portion of the clamp 42 abuts against the inner wall of the sealing bolt.
[0056] The rubber ferrule has a threading hole along the axial direction of the shell 1, and the threading hole is used for the connector 5 to pass through the rubber ferrule, so as to realize the connection between the connector 5 and the PCB adapter plate in the limiting groove 11, so that the rubber ferrule is wrapped around the outer wall of the connector 5 through the elastic deformation, thereby preventing liquid from entering the limiting groove 11 through the outer wall of the connector 5 and affecting the use effect and performance of the transducer.
[0057] In an example, the plug-in portion 411 includes a first plug-in hole 4111 and a second plug-in hole 4112 , the first plug-in hole 4111 is sealedly connected to the clamping member 42 , and the second plug-in hole 4112 is sealedly connected to the locking member 43 .
[0058] like Figure 5 As shown, the sealing member 41 is a sealing nut having a plug-in portion 411 opened in the axial direction.
[0059] The plug-in portion 411 includes a first plug-in hole 4111 and a second plug-in hole 4112. The first plug-in hole 4111 is used for plugging and connecting with the first elastic portion of the clamp 42, and the first elastic portion undergoes elastic deformation along the radial direction of the limiting groove 11 to seal the first plug-in hole 4111. The second plug-in hole 4112 is used for connecting with the locking member 43.
[0060] The first plug hole 4111 is in a truncated cone shape, and the size of the first plug hole 4111 matches the size of the first elastic portion. The first elastic portion is embedded in the first plug hole 4111 to achieve sealing between the sealing member 41 and the clamping member 42.
[0061] The second plug hole 4112 is columnar, and the size of the second plug hole 4112 matches the outer diameter of the locking member 43. An internal thread is provided in the second plug hole 4112, and the internal thread in the second plug hole 4112 matches the external thread on the outer wall of the locking member 43. The locking member 43 is connected to the sealing member 41 by threads.
[0062] Of course, in the embodiment of the present application, the plug-in portion 411 is not limited to the above structure, and those skilled in the art can configure it according to actual needs. For example, the plug-in portion 411 can also be configured as a plug-in hole that matches the shape of the card 42.
[0063] In one example, at least a portion of the locking member 43 is embedded in the second plug-in hole 4112, the outer wall of the locking member 43 abuts against the inner wall of the second plug-in hole 4112, the locking member 43 is sleeved on the clamping member 42, and the inner wall of the locking member 43 abuts against the clamping member 42.
[0064] like Figures 2 to 5 As shown, the outer wall of the locking member 43 is provided with an external thread, and the second plug hole 4112 is provided with an internal thread matching the external thread. The locking member 43 is embedded in the second plug hole 4112, and the locking member 43 and the second plug hole 4112 are connected by threads.
[0065] The clamping member 42 is embedded in the plug-in portion 411 and the locking member 43 to seal the wire and prevent liquid from flowing into the limiting groove 11 along the outer wall of the wire.
[0066] Of course, in the embodiment of the present application, the plug-in portion 411 is not limited to the above structure, and those skilled in the art can configure it according to actual needs. For example, the sealing member 41, the locking member 43 and the clamping member 42 can also be sealed by interference fit, and connected by thread locking.
[0067] In one example, the clamping member 42 has a first through hole 421 opened along the axial direction, and the locking member 43 has a second through hole 431 opened along the axial direction. The axial direction of the plug-in portion 411, the axial direction of the first through hole 421 and the axial direction of the second through hole 431 are the same, and at least a portion of the clamping member 42 is embedded in the second through hole 431.
[0068] like Figures 2 to 5 As shown, the clamp 42 has a first through hole 421 opened in the axial direction, that is, the first through hole 421 is used for the wire to pass through. The elastic material of the clamp 42 can prevent the liquid from flowing into the limiting groove 11 through the outer wall of the wire.
[0069] The locking member 43 has a second through hole 431 opened in the axial direction. The axial direction of the through hole is the same as the axial direction of the clamping member 42. The second elastic part of the clamping member 42 is embedded in the through hole. The diameter of the through hole matches the diameter of the second elastic part.
[0070] The locking member 43 is arranged on the plug-in portion 411 and is connected to the sealing member 41 by threads, which can not only prevent liquid from entering the limiting groove 11 through the plug-in portion 411, but also fix the clamping member 42 through the locking member 43 to prevent the clamping member 42 from elastically deforming and loosening, thereby affecting the sealing effect.
[0071] In one example, the seal 41 has a first sealing edge 412, and the inner wall of the shell 1 is provided with a first sealing groove 12; when the seal 41 is embedded in the limiting groove 11, the first sealing edge 412 is located in the first sealing groove 12, and the seal 41 is sealed and connected to the shell 1.
[0072] like Figure 5 As shown, a first sealing edge 412, such as a sealing ring, is provided on the outer wall of the sealing member 41. A first sealing groove 12 matching the first sealing edge 412 is provided on the inner wall of the housing 1. That is, when the housing 1 is connected to the sealing member 41, the sealing ring is embedded in the sealing groove to achieve sealing between the housing 1 and the sealing member 41, and the connection between the housing 1 and the sealing member 41 is achieved through the interference fit between the sealing member 41 and the housing 1.
[0073] Of course, in the embodiment of the present application, the plug-in portion 411 is not limited to the above structure, and those skilled in the art can configure it according to actual needs. For example, the seal 41 and / or the housing 1 are made of elastic material and can be elastically deformed, and the seal 41 and the housing 1 are sealed by interference fit, and the seal is achieved by the seal 41 and / or the housing 1 made of elastic material.
[0074] In one example, the sealing member 41 is provided with a second sealing groove 413 in the plug-in portion 411, and the locking member 43 is provided with a second sealing edge 432; when the locking member 43 is embedded in the plug-in portion 411, the second sealing edge 432 is located in the second sealing groove 413, and the sealing member 41 is sealed and connected to the locking member 43.
[0075] like Figure 5 As shown, the inner wall of the sealing member 41 is provided with a second sealing groove 413. The outer wall of the locking member 43 is provided with a second sealing edge 432, such as a rubber sealing ring, which matches the second sealing groove 413. That is, when the sealing member 41 is connected to the locking member 43, the sealing ring is embedded in the sealing groove, the sealing of the sealing member 41 and the locking member 43 is achieved through the sealing ring, and the connection is achieved through the interference fit between the locking member 43 and the plug-in portion 411.
[0076] Of course, in the embodiment of the present application, the plug-in portion 411 is not limited to the above structure, and those skilled in the art can configure it according to actual needs. For example, the seal 41 and / or the locking member 43 are made of elastic material and can be elastically deformed, the seal 41 and the locking member 43 are sealed, and the seal 41 and the locking member 43 are connected through interference fit.
[0077] In one example, the waterproof detachable ultrasonic transducer also includes a sealing gasket 6, which is arranged in the limiting groove 11, and the sealing gasket 6 is arranged between the sealing member 41 and the adapter 3, and the end of the connecting member 5 extending into the limiting groove 11 passes through the sealing gasket 6 and is connected to the adapter 3.
[0078] like Figures 2 to 4 As shown, the sealing pad 6 is an annular rubber pad. The annular rubber pad is arranged in the limiting groove 11, and the annular rubber pad is arranged between the sealing member 41 and the adapter 3. The end of the wire passes through the annular rubber pad and is connected to the PCB adapter plate. By providing the annular rubber pad, not only can the protection of the PCB adapter plate be improved, but also a certain waterproof effect can be achieved.
[0079] In an example, the clamping member 42 abuts against a side of the sealing gasket 6 that faces away from the adapter 3 .
[0080] like Figures 2 to 4 As shown, the sealing pad 6 is disposed between the clamp 42 and the PCB adapter board. The wire passes through the first through hole 421 of the clamp 42 and passes through the sealing pad 6 to be connected to the PCB board. The bottom of the clamp 42 abuts against the sealing pad 6 to improve the connection strength between the wire and the PCB board.
[0081] In an example, the tile 2 is bonded into the limiting groove 11 .
[0082] like Figures 2 to 4 As shown, a piezoelectric ceramic sheet 2 is provided in the housing 1 and at the bottom of the limiting groove 11. The piezoelectric ceramic sheet 2 is bonded to the bottom of the limiting groove 11 of the housing 1 by colloid. Bonding the piezoelectric ceramic sheet 2 by colloid not only reduces the damage to the piezoelectric ceramic sheet 2 by the rigid fixing object, but also fixes the position of the piezoelectric ceramic sheet 2, thereby preventing the piezoelectric ceramic sheet 2 from being displaced and affecting the use effect during use.
[0083] Of course, in the embodiment of the present application, the piezoelectric ceramic sheet 2 and the housing 1 are not limited to the above structure, and those skilled in the art can make configurations according to actual needs. The position of the piezoelectric ceramic sheet 2 can also be fixed by buckles or the like.
