Detailed Description

The technical scheme of the invention is further specifically described by the following embodiments and the accompanying drawings.

The utility model provides a circuit board immersion cleaning device, including washing bucket 1, this 1 bottoms of washing bucket are provided with outlet pipe 2, wherein 1 lateral wall top of washing bucket is provided with the dilatation groove 4 that the round cross-section is right trapezoid, this dilatation groove 4 sets up with washing bucket 1 an organic whole, and expand the lower bottom and the washing bucket 1 interior intercommunication in groove 4, and the inclined plane end in dilatation groove 4 is located the below, it is provided with round spray pipe 5 to expand simultaneously to hold 4 interior top inflection angle departments of groove, this spray pipe 5 is fixed at the 4 interior tops of dilatation groove through cassette locking, wherein evenly be provided with the hole for water spraying on the lower half lateral wall of spray pipe 5, and be provided with the water injection pipe 6 that runs through the 4 lateral walls of dilatation groove on the spray pipe 5.

During the use through the water pump through water injection pipe 6 with liquid leading-in spray pipe 5 in and spout by the hole for the spraying to evenly spray liquid in wasing bucket 1 by washing bucket 1 all around direction, make liquid be tiny pencil form and spray and prevent it to produce great sputter in wasing bucket 1, wherein the holding tank 4 top also can shelter from by the upward spun liquid of hole for the spraying makes it roll over and drop on the liquid level surface downwards.

Wherein, the expansion tank 4 can increase the liquid storage in the cleaning barrel 1, and when the water outlet pipe 2 discharges the liquid in the cleaning barrel 1, when the liquid level is lower than the capacity-expanding groove 4, the liquid and impurities in the capacity-expanding groove 4 will flow down along the inclined end and will not be deposited in the capacity-expanding groove 4, and the overflow pipe 16 is set on the side wall of the capacity-expanding groove 4, wherein the overflow pipe 16 is positioned below the water spray pipe 5, when the liquid level in the cleaning barrel 1 is higher, the overflow pipe 16 can be opened to discharge the liquid overflowing the top end of the cleaning barrel, the liquid level in the cleaning barrel 1 is prevented from overflowing the water spray pipe 5 to soak the cleaning barrel, and therefore the water inlet is influenced, or the liquid level is too high, causing the liquid to overflow from the top opening of the washing tub 1, and even if the liquid level in the washing tub 1 fluctuates greatly, it is rocked in the expansion tank 4 and shielded by the top wall thereof, so that the top end of the side wall of the washing tub 1 is not easily reached and overflows.

In the embodiment, a fixed grid 7 positioned below the containing groove 4 is arranged at the bottom in the cleaning barrel 1, wherein the middle of the top of the fixed grid 7 is provided with a protective cylinder 8 extending to the outside of the top of the washing barrel 1, and the top of the cleaning barrel 1 is provided with a rotating shaft 9 which passes through the protective cylinder 8 and extends into the cleaning barrel 1 below the fixed grid 7, the rotating shaft 9 is provided with a stirring paddle 10 positioned below the fixed grating 7, and the top of the fixed grating 7 is also provided with a supporting grating 11, wherein the middle part of the support grid 11 is provided with a round hole 12 which is sleeved on the protective cylinder 8, the bottom of the support grid 11 is provided with a spring 13 which is connected with the fixed grid 7, the edge of the support grid 11 is turned upwards to form a folded edge 14, wherein the top of the support grid 11 in the folded edge 14 is also uniformly provided with a support projection 15 for supporting the circuit board 3 to prevent the circuit board from clinging to the top end face of the support grid 11.

After filling up liquid in washing bucket 1, the motor of work drives stirring rake 10 through pivot 9 and rotates, thereby stir the liquid that is located fixed grid 7 bottom washing bucket 1 and make it produce the vortex, wherein the liquid that is stirred produces the vortex and drives liquid and product that support grid 11 top washing bucket 1 in rotate, the realization plays to stir abluent purpose to the product, because stirring rake 10 does not directly contact the product, so pivoted stirring rake 10 also can not damage the product, thereby the quality of product has been guaranteed. And because there is a protective barrel 8 in the process of the rotation of the rotating shaft, the circuit board 3 at the top of the support grid 11 is not easy to contact with the rotating shaft 9, so that the rotation of the rotating shaft 9 cannot be influenced, and meanwhile, the rotating shaft 9 cannot damage the rotating shaft.

As shown in fig. 2, when the circuit boards 3 are gradually added to the top of the support grid 11, the support grid 11 is squeezed to move downwards under the influence of the gravity of the circuit boards, the circular holes 12 move upwards and downwards on the protective cylinder 8, and simultaneously, the support grid 11 squeezes the springs 13 to contract the springs, when the circuit boards 3 are taken out after the cleaning is finished, when the circuit boards 3 on the upper half part of the cleaning barrel 1 gradually decrease, the gravity of the circuit boards 3 on the support grid 11 also gradually decreases, and then the springs 13 stretch to push the support grid 11 to move upwards, so that the gap between the circuit boards 3 on the top end surface of the support grid 11 and the top of the cleaning barrel 1 is reduced, and people can conveniently reach the circuit boards 3 to take out the circuit boards.

Meanwhile, when the stirring paddle 10 stirs the liquid in the cleaning barrel 1 to generate an upward vortex, the supporting grid 11 is pushed to move up and down and the spring 13 is driven to expand and contract, so that the top circuit board 3 is further driven to rotate or move, and the cleaning efficiency and effect are improved.

The present invention has been described in detail, but the above description is only a preferred embodiment of the present invention, and is not to be construed as limiting the scope of the present invention. All equivalent changes and modifications made within the scope of the present invention shall fall within the scope of the present invention.
