Description

Technical Field

[0001] The utility model relates to an ultrasonic transducer, in particular to an assembly structure of an ultrasonic transducer. Background Art

[0002] The applications of ultrasonic transducers are very extensive. They can be classified by the industries they are applied to, such as industry, agriculture, transportation, daily life, medical treatment, and military. They can be classified by the functions they achieve, such as ultrasonic processing, ultrasonic cleaning, ultrasonic detection, inspection, monitoring, telemetry, and remote control. They can be classified by the working environments, such as liquid, gas, and organism. They can be classified by their properties, such as power ultrasonic, detection ultrasonic, and ultrasonic imaging.

[0003] A part of the ultrasonic transducer is usually arranged inside the protective shell. Since the ultrasonic transducer is prone to getting hot during operation and affects the working efficiency, it is necessary to dissipate heat from it. Currently, most ultrasonic transducers on the market are equipped with a cooling fan inside the protective shell. However, the built-in cooling fan cannot quickly disperse the heat inside the protective shell. Especially for small ultrasonic transducers, the size of their protective shells is small, resulting in the use of only small-sized fans, and the heat dissipation effect is not ideal. Summary of the Utility Model

[0004] In order to overcome the disadvantages and deficiencies existing in the prior art, the purpose of the utility model is to design an assembly structure of an ultrasonic transducer. By installing a protective shell with ventilation openings outside the ultrasonic transducer and installing a wind guide and a cooling fan outside the protective shell, the heat dissipation effect of the ultrasonic transducer assembly structure can be improved.

[0005] To achieve the above purpose, the utility model provides an assembly structure of an ultrasonic transducer, which includes a hollow protective shell, a flange, a transducer, and a heat dissipation component communicated with the inside of the protective shell. A part of the transducer is located inside the protective shell, and another part is located outside the protective shell. The flange is fixedly connected to one end of the protective shell. The transducer passes through the flange. The heat dissipation component is located outside the protective shell. The heat dissipation component includes a wind guide and a cooling fan. One end of the wind guide is fixedly connected to the end of the protective shell away from the flange, and the other end is fixedly connected to the cooling fan. And the wind guide supplies power to the transducer and the cooling fan.

[0006] Further, the fixed part of the flange connected to the protective shell is a cuboid.

[0007] Further, the fixed part of the flange connected to the protective shell is a cylinder.

[0008] Further, the flange is provided with a quick-install chuck in a circular ring shape.

[0009] Further, a plurality of ventilation holes are provided on the side wall of the protective shell.

[0010] Furthermore, there are multiple ventilation holes, and the multiple ventilation holes are arranged evenly around the transducer.

[0011] Furthermore, the ventilation holes are arranged evenly along the axial direction of the protective housing.

[0012] Furthermore, the ultrasonic transducer assembly structure further includes a semi-circular pressing plate, and the flange is fixedly connected to the semi-circular pressing plate and clamps and fixes the transducer.

[0013] Furthermore, an electrical interface is provided on the side wall of the air guide.

[0014] Furthermore, the protective housing is in a hollow cylindrical shape.

[0015] After adopting the above technical solutions, the beneficial effects of the present utility model are as follows: The air guide and the cooling fan of the ultrasonic transducer of the present utility model are arranged outside the protective housing. The size of the cooling fan is not limited by the protective housing and is directly connected to the external air, greatly improving the air flow rate and the heat dissipation effect, thereby ensuring the stable operation of the ultrasonic transducer.

[0020] The technical solutions of the present utility model will be further described below through embodiments:

[0021]

Embodiment 1

[0022] The present utility model provides an ultrasonic transducer assembly structure. As shown in combination with Figures 1-2 , the ultrasonic transducer assembly structure includes a protective housing 4, a transducer 1 and a heat dissipation component. A part of the transducer 1 is located inside the protective housing 4, and another part is located outside the protective housing 4. The heat dissipation component is fixedly connected to one end of the protective housing 4 and the heat dissipation component is located outside the protective housing 4. The protective housing 4 is in a hollow cylindrical shape and there is a gap between it and the transducer 1. A plurality of ventilation holes 3 are provided on the side wall of the protective housing 4.

[0023] Although the protective shell 4 is in the shape of a hollow cylinder in this embodiment, in other embodiments, the protective shell 4 can also be in other hollow body shapes.

[0024] Specifically, the ultrasonic transducer assembly structure further includes a flange 2. One end of the protective shell 4 away from the heat dissipation component is fixedly connected to the flange 2, and the transducer 1 passes through the flange 2.

[0025] More specifically, the ultrasonic transducer assembly structure further includes a semi-circular pressing plate 9. The flange 2 is fixedly connected to the semi-circular pressing plate 9 and clamps and fixes the transducer 1.

[0026] Specifically, the heat dissipation component includes an air guide 6 and a cooling fan 7. An electrical interface 5 is provided on the side wall of the air guide 6. One end of the air guide 6 is fixedly connected to the protective shell 4, and the other end is fixedly connected to the cooling fan 7. When the air guide 6 drives the cooling fan 7 to operate, air flow is sent into the protective shell 4 and flows out through the ventilation holes 3 on the protective shell 4, taking away the heat generated when the transducer 1 works.

[0027] The above ultrasonic transducer assembly structure can be used in cooperation with a cleaning container or a liquid processing device. For example, when used in cooperation with a cleaning container, the exposed part of the transducer 1 can be extended into the clear water of the cleaning container, and the flange 2 is fixedly connected to the upper cover of the cleaning container.

[0028] In this embodiment, the part of the flange 2 fixedly connected to the protective shell 4 is a cuboid, and the four corners of the flange 2 are all rounded. In other embodiments, the part of the flange 2 fixedly connected to the protective shell 4 can also be in other shapes, such as a cylinder, a regular hexagonal prism, etc., as long as it can play a role in connection and fixation.

[0029]

Embodiment 2

[0030] As Figure 3 shown, the protective shell 4, the transducer, and the heat dissipation component in this embodiment are all the same as those in Embodiment 1 and will not be described in detail here. Different from Embodiment 1, in this embodiment, the part of the flange 2 fixedly connected to the protective shell 4 is a cylinder, and the flange 2 is provided with a quick-install chuck 8 in the shape of a ring. When used in cooperation with a liquid processing device, the exposed part of the transducer 1 is extended into the liquid of the liquid processing device, and the quick-install chuck 8 cooperates with the clamp of the liquid processing device to form a fixation; the sealing ring of the clamp is in close contact with the quick-install chuck 8, thus achieving the effects of water tightness and air tightness.
