The advantages of this invention are: simpler and more efficient assembly of the entire connection structure between the tail cable and the handle; good waterproof performance of the solder joints; and a longer service life for the handle.

Description

Technical Field

[0001] This invention relates to dental ultrasonic medical devices, and more particularly to a handle encapsulation structure. Background Technology

[0002] Dental ultrasonic medical equipment refers to electrical medical devices that achieve their intended effects and functions through ultrasonic vibrations generated by ultrasonic transducers, including ultrasonic scalers and ultrasonic bone scalpels. Ultrasonic scalers primarily use a high-frequency oscillation circuit to generate high-frequency oscillation signals, which are then applied to the ultrasonic transducer. Utilizing the inverse piezoelectric effect, ultrasonic vibrations are generated, exciting the working tip to resonate. The tip then directly contacts plaque, tartar, dental plaque, and tea stains, producing a scraping or shearing effect, removing the contaminant layer attached to the root canal wall, thus achieving root canal cleaning and rinsing. Ultrasonic bone scalpels utilize high-intensity focused ultrasound technology. Through a transducer, electrical energy is converted into mechanical energy. High-frequency ultrasonic oscillation causes water vaporization within the contacted tissue cells and the breakage of protein hydrogen bonds, thereby thoroughly destroying the bone tissue that needs to be cut during surgery. The handle is the core component of dental ultrasonic medical equipment; its performance and lifespan directly determine the performance and lifespan of the entire device. Existing handles have the following drawbacks: cumbersome assembly of the tail plug and poor waterproofing of the solder joints, resulting in a short handle lifespan. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a handle packaging structure to overcome the shortcomings of the prior art.

[0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a handle encapsulation structure, which includes at least a shell, a socket, a tail sleeve a, and a sealing structure. The tail sleeve a is connected to the tail end of the shell, and the socket is disposed inside the tail end of the shell. The socket is provided with an injection hole. The shell and the tail sleeve a are filled with glue that is resistant to temperatures above 150°C. The glue encapsulates all the solder joints of the socket. The sealing structure seals the opening at the end of the tail sleeve a away from the shell.

[0005] The beneficial effects of this invention are: the assembly of the connection structure between the entire tail cable and the handle is simpler and more efficient, the solder joints have good waterproof performance, and the handle has a long service life.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Further: The sealing structure includes a sealing ring, a tail sleeve b and a tail sleeve c. The tail sleeve b is connected to the opening at the end of the tail sleeve a away from the outer shell through the tail sleeve c. The sealing ring is located between the tail sleeve b and the tail sleeve a, and its two ends abut against the tail sleeve b and the tail sleeve a respectively. The sealing ring has multiple through holes for power supply lines and water pipes to pass through.

[0008] Furthermore, the sealing structure also includes a fixing frame, which is located between the tail sleeve b and the sealing ring, and the sealing ring is fixed to the fixing frame.

[0009] Further: Tail sleeve c and tail sleeve a are connected by a threaded connection.

[0010] Further: The adhesive used is epoxy or silicone.

[0011] Further: The socket is equipped with a through hole for the water pipe to pass through. Attached Figure Description

[0012] Figure 1 This is a cross-sectional view of the handle packaging structure described in this invention. Detailed Implementation

[0013] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0014] Example 1

[0015] like Figure 1 As shown, a handle encapsulation structure includes at least a housing 1, a socket 2, a tail sleeve a3, and a sealing structure 4. The tail sleeve a3 is connected to the tail end of the housing 1. The socket 2 is disposed inside the tail end of the housing 1 and has an injection hole 220. The housing 1 and the tail sleeve a3 are filled with adhesive that is resistant to temperatures above 150°C. The adhesive encapsulates all the solder joints of the socket 2. The sealing structure 4 seals the opening of the tail sleeve a3 at the end away from the housing 1.

[0016] During encapsulation, first install the socket 2 into the corresponding position inside the outer shell 1, then inject an appropriate amount of fluid adhesive with a temperature resistance of 150°C or higher through the injection hole 220. After the adhesive has cured, install the tail sleeve a3 onto the outer shell 1. Specifically, the tail sleeve a3 can be connected to the outer shell 1 by threads, and then an appropriate amount of fluid adhesive with a temperature resistance of 150°C or higher can be injected into the tail sleeve a3. It is best to install the sealing structure 4 and place the whole assembly in an oven to dry or cure naturally.

[0017] Example 2, as Figure 1 As shown, this embodiment is a further optimization based on embodiment 1, and its specific details are as follows:

[0018] The sealing structure 4 includes a sealing ring 410, a tail sleeve b420, and a tail sleeve c430. The tail sleeve b420 is connected to the opening at the end of the tail sleeve a3 away from the outer casing 1 through the tail sleeve c430. The sealing ring 410 is disposed between the tail sleeve b420 and the tail sleeve a3, and its two ends abut against the tail sleeve b420 and the tail sleeve a3 respectively. The sealing ring 410 has multiple through holes for power supply lines and water pipes to pass through. Specifically, after the tail sleeve c430 and the tail sleeve a3 are connected in place, the sealing ring 410 will be squeezed by the action of the tail sleeve b420 and the tail sleeve a3. The sealing ring 410 has 5 through holes, of which 4 are used for passing through power lines and the remaining 1 is used for passing through water pipes.

[0019] Furthermore, the sealing structure 4 also includes a fixing frame 440, which is disposed between the tail sleeve b420 and the sealing ring 410, and the sealing ring 410 is fixed to the fixing frame 440.

[0020] Specifically, it could be:

[0021] Tail sleeve a3 has a step inside, and sealing ring 410 is fixed to the end of tail sleeve b420. Tail sleeve c430 is fitted onto tail sleeve b420. Tail sleeve c430 and tail sleeve a3 are connected by a threaded connection. Rotating tail sleeve c430 causes tail sleeve c430 to rotate with tail sleeve a3, thereby causing sealing ring 410 to be squeezed by the combined action of the step of tail sleeve a3, tail sleeve b420, tail sleeve c430 and fixing bracket 440 to achieve sealing.

[0022] Typically, the sealing ring 410 can be a silicone sealing ring.

[0023] Example 3, as Figure 1 As shown, this embodiment is a further optimization based on embodiment 1 or 2, and its specific details are as follows:

[0024] The adhesive used is epoxy or silicone, or other adhesives with good fluidity and a temperature resistance of 150°C or higher.

[0025] Example 4, as Figure 1 As shown, this embodiment is a further optimization based on embodiment 1, 2, or 3, and its specific details are as follows:

[0026] The socket 2 is provided with a through hole 210 for the water pipe to pass through.

[0027] In various embodiments, the handle encapsulation structure further includes a transducer 5, a top sleeve 6, a plug 7, and a water pipe 8. The transducer 5 is disposed inside the housing 1 and is fixed to the housing 1 by the plug 7. The top sleeve 6 is disposed inside the housing 1 and is located between the transducer 5 and the socket 2. One end of the water pipe 8 is connected to the water inlet of the transducer 5, and the other end passes through the top sleeve 6, the through hole 210, the tail sleeve a3, the sealing ring 410, the fixing bracket 440, and the tail sleeve b420 in sequence.
