Specifically, the cleaning assembly 100 includes a first housing 110, a component placement member 120, and an ultrasonic transducer 130, the first housing 110 is provided with a cleaning cavity 111, the component placement member 120 is disposed in the cleaning cavity 111, the ultrasonic transducer 130 is disposed on an outer wall of the first housing 110, and the ultrasonic transducer 130 and the component placement member 120 are disposed at an interval; the distance adjusting assembly 200 is disposed on the first housing 110, the distance adjusting assembly 200 includes a driving source 210, a first adjusting member 220 in driving connection with the driving source 210, and a second adjusting member 230 movably connected with the first adjusting member 220, the second adjusting member 230 is connected to the placing member 120, the first adjusting member 220 is used for being driven by the driving source 210 to move the second adjusting member 230, so that the placing member 120 is close to or far away from the ultrasonic transducer 130.

More specifically, the parts placement member 120 is used to place parts, and the ultrasonic transducer 130 is used to generate cleaning impact force of cleaning agents contained in the cleaning chamber 111.

In the above-described ultrasonic cleaning machine, since the parts placement member 120 is disposed in the cleaning chamber 111 of the first housing 110 and the ultrasonic transducer 130 is disposed on the outer wall of the first housing 110, the cleaning agent in the cleaning chamber 111 can be given a cleaning impact by the ultrasonic transducer 130, so that the parts on the parts placement member 120 can be cleaned in the cleaning chamber 111.

In addition, in the distance adjusting assembly 200, since the first adjusting member 220 is drivingly connected to the driving source 210, the second adjusting member 230 is movably connected to the first adjusting member 220, and the second adjusting member 230 is also connected to the parts placement member 120, when the second adjusting member 230 moves relative to the first adjusting member 220, the parts placement member 120 can move relative to the first adjusting member 220 along with the second adjusting member 230. Also, since the first regulating member 220 is used to move the second regulating member 230 by the driving of the driving source 210, the parts placing member 120 can move along with the second regulating member 230 when the driving source 210 drives the first regulating member 220 to move the second regulating member 230. Since the ultrasonic transducer 130 is spaced apart from the parts placement member 120, the parts placement member 120 can be moved closer to or farther from the ultrasonic transducer 130 when the parts placement member 120 moves along with the second adjusting member 230.

When the part placement member 120 is close to the ultrasonic transducer 130, the ultrasonic energy can be increased without replacing the ultrasonic transducer 130, so as to avoid the situation that the part cannot be thoroughly cleaned due to too small ultrasonic energy. When part holder 120 is far from ultrasonic transducer 130, ultrasonic energy can be reduced without replacing ultrasonic transducer 130 to avoid damage to the part being cleaned due to too much ultrasonic energy. Therefore, the distance between the part placing member 120 and the ultrasonic transducer 130 can be adjusted to change the amount of the ultrasonic energy, thereby improving the cleaning effect on the part.

As shown in fig. 2, in one embodiment, the ultrasonic transducer 130 and the component placement member 120 are vertically spaced, the first adjusting member 220 is an adjusting rod, the adjusting rod is vertically disposed, one end of the adjusting rod is drivingly connected to the driving source 210, the second adjusting member 230 is connected to the adjusting rod, and the second adjusting member 230 is capable of moving on the adjusting rod in a direction approaching or departing from the ultrasonic transducer 130.

Since the adjusting rod is disposed along the vertical direction and the second adjusting member 230 can move on the adjusting rod toward the direction close to or away from the ultrasonic transducer 130, the driving source 210 can drive the adjusting rod to rotate, so that the second adjusting member 230 can move on the adjusting rod toward or away from the ultrasonic transducer 130 along the vertical direction, and since the ultrasonic transducer 130 and the part placing member 120 are disposed at an interval in the vertical direction, when the second adjusting member 230 moves on the adjusting rod toward or away from the ultrasonic transducer 130 along the vertical direction, the part placing member 120 can move along with the second adjusting member 230 toward the direction close to or away from the ultrasonic transducer 130. Therefore, under the condition of not replacing the ultrasonic transducer 130, the distance between the part placing member 120 and the ultrasonic transducer 130 can be adjusted to change the ultrasonic energy, so as to avoid the influence on the cleaning effect caused by too large or too small ultrasonic energy in the process of cleaning the parts.

Specifically, the driving source 210 can still drive the adjusting lever to rotate during the part washing work, so that the second adjusting member 230 moves in a vertical direction on the adjusting lever.

More specifically, there are four sets of the distance-adjusting assemblies 200, the four sets of the distance-adjusting assemblies 200 are uniformly disposed on the first housing 110, and the second adjusting member 230 of each set of the distance-adjusting assemblies 200 is connected to the parts placement member 120. During the operation of the distance adjustment assemblies 200, the driving sources 210 of the four sets of distance adjustment assemblies 200 are simultaneously activated, so that the second adjustment members 230 in each set of distance adjustment assemblies 200 can simultaneously move in the vertical direction on the corresponding adjustment rods, thereby improving the stability of the parts placement member 120 when moving in the direction approaching or moving away from the ultrasonic transducer 130.

As shown in fig. 2, in one embodiment, the adjusting rod is a worm, the second adjusting member 230 is a worm wheel, and the worm is driven by the driving source 210 to mesh with the worm wheel.

More specifically, the driving source 210 may be a motor, and may be any shaft driver capable of driving the adjustment lever to rotate.

In this way, when the driving source 210 drives the worm to rotate, the worm wheel in mesh transmission with the worm can move on the worm in the vertical direction, so that the part placement member 120 connected with the worm wheel can move along the worm wheel in the vertical direction, thereby achieving the purpose that the part placement member 120 moves towards the direction close to or away from the ultrasonic transducer 130, and thus adjusting the distance between the part placement member 120 and the ultrasonic transducer 130. And, mounting groove 1111 can provide certain limiting displacement for the worm wheel, prevents that the worm wheel from appearing disengaging the phenomenon when meshing with the worm, improves driven stability.

Specifically, in other embodiments, the adjusting rod may also be a rack, and the second adjusting member 230 may also be a gear, and the gear is engaged with the rack to move on the rack in the vertical direction.

Because the water outlet is provided with the filtering member 140, the waste residue in the cleaning cavity 111 can be collected in the filtering member 140, and the waste residue in the cleaning cavity 111 can be ensured not to flow to the drain pipe 150, so that the drain pipe 150 can be prevented from being blocked by the waste residue, and the smoothness of the drain pipe 150 can be ensured. When the cleaning agent in the cleaning chamber 111 needs to be replaced, the outlet valve 160 on the drainage pipe 150 is opened, and the waste cleaning agent can flow out of the cleaning chamber 111 through the drainage pipe 150.
