[0048] In the purification device, the installation cavity 330 of the waterproof seat 300 serves as the connection place between the first connecting pin 130 of the ultrasonic transducer 100 and the first wire 220 of the conveying component 200, wherein the shell portion 110 of the ultrasonic transducer 100 is sealed in the installation hole 311, and the first connecting pin 130 is located in the installation cavity 330; the conveying component 200 is sealed in the wire entry hole 321, and the output end of the first wire 220 is located in the installation cavity 330, that is, the conveying component 200 and the ultrasonic transducer 100 seal the installation cavity 330 as a sealed chamber, and the first wire 220 is connected to the first connecting pin 130 in the installation cavity 330, and the installation cavity 330 plays a water-proof role, thereby reducing or even avoiding the occurrence of water soaking the circuit connection of the ultrasonic transducer 100 when the purification device is running, thereby ensuring the normal use of the purification device.

Here is a specific form of the ion generator 400, in which one of the first generating tube 420 and the second generating tube 430 is an anode generating tube, and the other is a cathode generating tube. Taking the first generating tube 420 as an anode generating tube and the second generating tube 430 as a cathode generating tube as an example, the first cylinder 413 on the first generating tube 420 is an anode cylinder, and the second cylinder 414 on the second generating tube 430 is a cathode cylinder; there are multiple second wires 230, among which the second wire 230 connected to the positive pole of the power supply is connected to the anode cylinder, and the second wire 230 connected to the negative pole of the power supply is connected to the cathode cylinder.

[0063] Among them, the insulating pad 440 is isolated between the first generating tube 420 and the second generating tube 430 to ensure that the first generating tube 420 and the second generating tube 430 are in a non-direct contact state; in addition, the insulating pad 440 can also limit the position where the first column 413 is inserted into the third through hole 432 to reduce the short circuit phenomenon caused by the connection between the first column 413 and the hole wall of the third through hole 432, and ensure the normal operation of the ion generator 400.

[0064] Specifically, Figure 5 and Figure 6As shown, there are three first columns 413, which are evenly spaced along the circumference of the first flange 421.

[0065] Specifically, a second boss 350 may be provided in the mounting cavity 330, and the embedding hole 351 passes through the second boss 350 to lengthen the embedding hole 351 and improve the connection sealing performance between the conductive leg 410 and the embedding hole 351. The sum of the number of the second boss 350, the number of the first column 413, and the number of the second column 414 is six, and the six second bosses 350 and the three first bosses 340 are arranged around the edge of the mounting hole 311 along the circumference of the mounting hole 311.

When in use, the water in the tank body 600 can enter it through the water hole 510, and contact with the ultrasonic transducer 100 and the ion generator 400, so as to ensure the normal operation of the purification device; the protective cover 500 can protect the ultrasonic transducer 100 and the ion generator 400, reduce the damage caused by external factors such as collision to the two, and thus extend the service life of the purification device.

[0067] In this embodiment, a connecting ring 360 can be provided on the waterproof seat 300, and the connecting ring 360 is threadedly connected to the protective cover 500. This is a specific connection method between the protective cover 500 and the waterproof seat 300. The protective cover 500 is threadedly connected to the waterproof seat 300 through the connecting ring 360. After using for a period of time, the protective cover 500 can be unscrewed, and the ion generator 400 and the ultrasonic transducer 100 can be cleaned. After cleaning, the protective cover 500 can be reconnected to the connecting ring 360. Specifically, Fig.10 As shown, a connecting ring 520 can be connected to the open end of the protective cover 500, and an internal thread is provided on the inner wall of the connecting ring 520, and an external thread is provided on the outer wall of the connecting ring 360, and the internal thread cooperates with the external thread; the protective cover 500 can be made of stainless steel material, and the connecting ring 520 can be a plastic part. The connecting ring 520 and the protective cover 500 are connected by gluing. The cost of processing the internal thread on the connecting ring 520 is much lower than that of processing the internal thread on the protective cover 500, thereby reducing the processing cost.

[0068] In this embodiment, the ultrasonic transducer 100 and the ion generator 400 are both located in the ring of the connecting ring 360, and the connecting ring 360, the ultrasonic transducer 100, the ion generator 400 and the protective cover 500 are coaxially arranged.

[0070] Specifically, Fig.12 As shown, the installation position 610 may include a placement table 611 and a threading hole 612 located inside the placement table 611. The waterproof seat 300 or the protective cover 500 of the purification device is placed on the placement table 611, and the wire tube 210 passes through the threading hole 612. The plug at the end of the wire tube 210 is connected to an external power supply, and the length of the wire tube 210 between the power supply and the threading hole 612 is sufficient. When the purification device needs to be used, the waterproof seat 300 is directly removed and placed in the slot 600. The wire tube 210 extends out of the threading hole 612 as the waterproof seat 300 is pulled, which greatly improves the convenience of using the purification device.

[0071] In this embodiment, a liquid level sensor and a control switch for controlling the switch state of the ultrasonic transducer 100 can also be set in the waterproof seat 300, and a processor is provided in the installation cavity 330, and the liquid level sensor and the control switch are connected to the processor. When the waterproof seat 300 is immersed in the water of the tank body 600, the liquid level sensor senses the water level, and transmits an open electrical signal to the processor, and the processor controls to open the control switch accordingly, and the ultrasonic transducer 100 and the ion generator 400 are turned on; after the purification is completed, the water in the tank body 600 is drained or the waterproof seat 300 is taken out of the tank body 600. The liquid level sensor cannot sense the water level, and then transmits a close electrical signal to the processor, and the processor closes the control switch accordingly, and the ultrasonic transducer 100 and the ion generator 400 are turned off, and the purification stops.

[0072] It should be noted that the program settings such as signal transmission between the above-mentioned processor and the liquid level sensor and control switch belong to the prior art and do not belong to the improvement of this application, and will not be repeated here.
