Abstract
The invention discloses a coaxial waterproof high-temperature-resistant ultrasonic emulsification handle, which is different from other handles in that a cylindrical waterproof shell made of PPP material is designed and installed between an amplitude transformer of a transducer and a metal shell to isolate cooling water from a transducer vibrator. When the heat exchanger works, cooling water flows to fill the space between the PPP protective shell and the metal shell, so that heat generated by the work of the transducer vibrator is taken away, and the transducer vibrator is ensured to work continuously and stably. The invention has the beneficial effects that: first, the heat dissipation capacity is large and the heat dissipation is fast. The ultrasonic emulsification handle can work more forcefully and stably. Secondly, the cooling water evenly encircles around the transducer, and the cooling effect is good, and the temperature is even, can not go out to have the local cooling and the local refrigerated condition that does not have in some places, local overheat can not appear. Third, the metal housing does not generate heat. Because a layer of water and a layer of PPP are separated from the transducer, and a layer of air is arranged at the innermost part, the metal shell is not hot, and the operation is convenient. The condition that the handle is hot when the transducer works can not occur. Fourthly, the PPP shell is an insulator, so that sparking or short circuit between the transducer oscillator electrode and the metal shell can be avoided to the maximum extent.

Furthermore, the cylindrical shell is insulated, so that short circuit or ignition and discharge between the transducer electrode and the metal shell can be effectively prevented, and the safety of the transducer can be effectively improved.
The invention discloses a coaxial waterproof high-temperature-resistant ultrasonic emulsification handle which is mainly characterized in that a waterproof shell made of PPP material is added between an energy converter and a metal shell to isolate cooling water from an energy converter vibrator. When the heat exchanger works, cooling water flows to fill the space between the PPP protective shell and the metal shell, so that heat generated by the work of the transducer vibrator is taken away, and the transducer vibrator is ensured to work continuously and stably.
The invention has the beneficial effects that: first, the heat dissipation capacity is large and the heat dissipation is fast. The ultrasonic emulsification handle can work more forcefully and stably. Secondly, the cooling water evenly encircles around the transducer, and the cooling effect is good, and the temperature is even, can not go out to have the local cooling and the local refrigerated condition that does not have in some places, local overheat can not appear. Third, the metal housing does not generate heat. Because a layer of water and a layer of PPP are separated from the transducer, and a layer of air is arranged at the innermost part, the metal shell is not hot, and the operation is convenient. The condition that the handle of the transducer working chamber is hot can not occur. Fourthly, the PPP shell is an insulator, so that sparking or short circuit between the transducer oscillator electrode and the metal shell can be avoided to the maximum extent.
