The installation structure of the ultrasonic transducer of the utility model plays multiple roles of positioning, sealing, and anti-coupling, thereby reducing the measurement caused by the coupling interference between the ultrasonic signal and the valve body.

[0004] The above-mentioned prior art solutions have the following defects: it is not convenient to fix the position of the ultrasonic transducer, it is not convenient to achieve double-layer sealing of the ultrasonic transducer, and it is not convenient to quickly disassemble and unlock the ultrasonic transducer. Therefore, the utility model provides an ultrasonic transducer with a sealing structure to solve the above-mentioned problems. Utility Model Content

[0025] The outer end of the groove 3 is fixedly arranged inside the connector 2, and a first spring 4 and a baffle 5 are installed inside the groove 3, and the baffle 5 is located on the left side of the first spring 4. A first clamping block 6 and a second spring 7 are installed inside the two ends of the lower end of the groove 3, and the second spring 7 is located on the outside of the first clamping block 6, and a hole groove 8 is provided in the middle of the first clamping block 6;

[0026] The converter body 9 is connected to the inside of the connector 2, and a first sealing ring 10 is provided in the middle of the upper end of the converter body 9, and a second sealing ring 11 is provided inside the upper end of the converter body 9, and a sliding rod 12 and a third spring 13 are installed on the left and right sides of the upper end of the converter body 9, and the third spring 13 is located at the outer end of the sliding rod 12, a second clamping block 14 is fixed on the right side of the sliding rod 12, and a third clamping block 15 is provided at the upper and lower ends of the second clamping block 14, and a clamping groove 16 is provided at the upper and lower ends of the right side of the second clamping block 14.

[0027] like Figure 1 and Figure 3 As shown, the first spring 4 is arranged at equal intervals on the right side of the baffle 5, and the baffle 5 forms a sliding structure inside the groove 3, the first clamping block 6 forms a sliding structure inside the upper end of the groove 3, and the lower end of the first clamping block 6 is connected to the clamping slot 16 in a clamping manner, so as to fix the position of the converter.

[0028] like Figure 3 As shown, the interior of the hole groove 8 is arranged in a fitted state with the third clamping block 15, and the right side of the third clamping block 15 is arranged in an inclined state.

[0029] like Figure 2 As shown, the sliding rod 12 forms a sliding structure at the upper end of the converter body 9, and the third spring 13 is arranged at the outer end of the sliding rod 12 in a fitted state.

[0030] like Figure 2 and Figure 3 As shown, the cross section of the second clamping block 14 is an arc-shaped structure, and the interior of the groove 3 is connected to the second clamping block 14 in a clamping manner.

[0031] Working principle: When using the ultrasonic transducer with a sealed structure, Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, first, the converter body 9 and the connector 2 are rotated and meshed together, and the first sealing ring 10 at the upper end of the converter body 9 is fitted with the inside of the connector 2, and the lower end of the connector 2 is fitted with the second sealing ring 11, which ensures that the ultrasonic transducer can effectively clean the fruits and vegetables that need to be cleaned inside the sink 1. At the same time, in order to ensure that the position of the converter body 9 is fixed and connected to avoid falling off, the sliding rod 12 is pushed toward the middle of the connector 2, so that the sliding rod 12 squeezes the third spring 13 during the movement to drive the second clamping block 14 to engage with the inside of the groove 3. In order to stabilize the position of the second clamping block 14, when the second clamping block 14 enters a certain position inside the groove 3, the third spring 13 is pressed against the second clamping block 14. A card block 6 has been inserted into the inside of the card slot 16 through the rebound of the second spring 7, thereby fixing the position of the second card block 14 and limiting the converter body 9. When the converter body 9 needs to be disassembled, the sliding rod 12 drives the second card block 14 to squeeze the baffle 5 and the first spring 4, so that the second card block 14 drives the third card block 15 to move the first card block 6 upward through the hole groove 8 during movement, and the engagement with the second card block 14 can be disengaged. After the disengagement position, the first spring 4 rebounds through the baffle 5 to pop the second card block 14 out of the inside of the groove 3, and the converter body 9 can be disassembled. This is the method of using the ultrasonic transducer with a sealing structure.
