Description

Technical Field

[0001] The present invention relates to the technical field of ultrasonic cleaning equipment, and particularly to an ultrasonic cleaner with a cleaning liquid circulation and filtration function. Background Art

[0002] An ultrasonic cleaner is a device that uses the cavitation effect, acceleration effect, and rectilinear flow effect of ultrasonic waves in a liquid to directly and indirectly act on the liquid and dirt, so that the dirt layer is dispersed, emulsified, and peeled off to achieve the purpose of cleaning. With its advantages of high efficiency, environmental protection, strong applicability, and safety, the ultrasonic cleaner has been widely used in many fields.

[0003] For example, an ultrasonic cleaner with a filtering function disclosed in the publication number: CN215466606U, includes a machine body. One side of the machine body is provided with a discharge pipe. One end of the discharge pipe is penetrated with a filtering box. The filtering box is provided with a filtering mechanism. One lower end of one side of the filtering box is penetrated with a conveying pipe, and a water pump is installed on the conveying pipe. The utility model can, through the use of the filtering mechanism and the buckling mechanism, filter the cleaning solvent with impurities discharged by the ultrasonic cleaner through the filtering mechanism, so that the cleaning solvent can be reused, effectively reducing the cleaning cost of the ultrasonic cleaner. At the same time, through the buckling mechanism, when the filter rack and the filter net need to be cleaned, the filter rack and the filter net can be more conveniently taken out of the filtering box for cleaning, effectively ensuring the filtering effect of the cleaning solvent.

[0004] Although the above ultrasonic cleaner can clean the cleaning solvent, its efficiency in circulating and filtering the cleaning agent in the ultrasonic cleaner is still insufficient, and the cleanliness of adsorbing various impurities in the cleaning agent is also insufficient, thereby reducing the stability of the ultrasonic cleaning agent for subsequent reuse. Therefore, an ultrasonic cleaner with a cleaning liquid circulation and filtration function is needed to solve the problems raised above. Summary of the Invention

[0005] The purpose of the present invention is to provide an ultrasonic cleaner with a cleaning liquid circulation and filtration function to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: An ultrasonic cleaner with a cleaning liquid circulation and filtration function, including an ultrasonic cleaning machine body for support. Two sets of feeding devices are arranged in front of the lower end surface of the ultrasonic cleaning machine body.

[0007] Filtering device, there are two groups of the filtering devices in total, and both groups of the filtering devices are arranged at the rear part of the lower end face of the ultrasonic cleaning machine body. The front end faces of the two groups of the filtering devices are meshed and connected through a second synchronous belt, and a first synchronous belt pulley is arranged at the center of the front end face of the feeding device;

[0008] Transmission device, the transmission device is fixedly arranged at the side ends of the filtering device and the feeding device, and the transmission device is meshed and connected with the feeding device through a first synchronous belt;

[0009] Motor holder, the motor holder is fixedly arranged at the front end face of the feeding device opposite to the first synchronous belt pulley, and a servo motor is fixedly arranged at the center of the outer end face of the motor holder.

[0010] Preferably, the filtering device includes a filtering box body. Two groups of first one-way valves are arranged at the side end face of the filtering box body near the top, and a liquid guiding pipe is fixedly arranged at the output end of the first one-way valve. A transmission clamping shaft is rotationally clamped at the center of the inner end face of the filtering box body, and two groups of fixed guiding shafts are fixedly arranged at the outer end face of the transmission clamping shaft. Cam chutes are arranged at the outer end faces of the two groups of fixed guiding shafts. A transmission worm gear is arranged at the end of the inner end face of the transmission clamping shaft. A positioning guide seat is slidably clamped at the inner end face of the filtering box body through the cam chute, and five groups of filtering and adsorbing plates are symmetrically and equidistantly clamped at the inner end face of the positioning guide seat. A guiding chute is arranged at the center of the inner end face of the positioning guide seat, and a guiding sliding shaft is fixedly arranged at the inner end face of the guiding chute. A sealing cover plate is fixedly arranged at the center of the upper end face of the filtering box body.

[0011] Preferably, the transmission device includes four groups of limiting rotating seats for support. A transmission guiding shaft is rotationally clamped at the inner end faces of the four groups of limiting rotating seats, and a first synchronous belt pulley is fixedly arranged at the center of the side end face of the transmission guiding shaft. A transmission worm is arranged at the inner end face of the transmission guiding shaft near the middle.

[0012] Preferably, the feeding device includes a liquid changing box body for support. A third one-way valve is arranged at the side end face of the liquid changing box body near the upper part, and a sealing guide seat is fixedly arranged at the center of the upper end face of the liquid changing box body. A second one-way valve is fixedly arranged at the center of the upper end face of the sealing guide seat. A transmission chuck is rotationally clamped at the side part of the inner end face of the liquid changing box body, and a second synchronous belt pulley is arranged at the center of the side end face of the transmission chuck away from the third one-way valve. A fixed shifting shaft is arranged inside the side end face of the transmission chuck. A sealing sliding seat is slidably clamped at the inner end face of the liquid changing box body through the fixed shifting shaft, and a support guiding groove is arranged at the center of the side end face of the sealing sliding seat.

[0013] Preferably, the positioning guide seat is adapted to the fixed guide shaft through the guiding chute and to the guiding sliding shaft through the cam chute, and is then slidably clamped inside the filter box body. When adsorbing and filtering the cleaning liquid inside the filter box body, the fixed guide shaft can drive the two groups of positioning guide seats and the filter adsorption plates to circulate and filter and adsorb the cleaning liquid inside the filter box body through the adaptation of the cam chute and the guiding sliding shaft.

[0014] Preferably, the driving worm is meshed with the driving worm gear, and the first synchronous pulley is meshed with the first synchronous belt through the first synchronous belt, which can effectively improve the transmission stability of the subsequent equipment and also improve the power utilization efficiency of the equipment.

When circulating and exporting the cleaning liquid inside the ultrasonic cleaning machine body, the driving chuck can drive the sealing sliding seat to move up and down inside the liquid changing box body in a cycle through the sliding limit of the fixed shifting shaft and the supporting guide groove, so that a cyclic negative pressure is generated inside the liquid changing box body to adsorb the cleaning liquid inside the ultrasonic cleaning machine body, and at the same time, when moving up, the cleaning liquid is introduced into the filter box body through the third one-way valve under positive pressure for filtering.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. By setting the filtering device and the material guiding device, when cleaning the impurities in the cleaning liquid, the two groups of material guiding devices can unidirectionally lead out the cleaning liquid inside the ultrasonic cleaning machine body in equal amounts and introduce it into the filtering device in equal amounts, effectively improving the stability of the equipment for leading out the cleaning liquid, and at the same time providing enough time for the filtering device to filter and adsorb the cleaning liquid. Moreover, the filtering device can continuously filter and adsorb the cleaning liquid in a cycle, maximizing the cleaning efficiency and cleanliness of the impurities in the cleaning liquid by the equipment.

[0019] 2. When the present invention is in transmission, the servo motor can synchronously drive the second synchronous pulley and the first synchronous pulley to rotate.

At the center of the inner end face of the positioning guide seat 25, a guiding sliding groove 28 is provided, and a guiding sliding shaft 27 is fixedly arranged at the inner end face of the guiding sliding groove 28. At the center of the upper end face of the filtering box body 210, a sealing cover plate 24 is fixedly arranged.

[0038] The transmission device 3 includes four groups of limiting rotating seats 33 for support. At the inner end faces of the four groups of limiting rotating seats 33, a transmission guiding shaft 34 is rotationally clamped, and a first synchronous pulley 31 is fixedly arranged at the center of the side end face of the transmission guiding shaft 34. At the middle part near the inner end face of the transmission guiding shaft 34, a transmission worm 32 is provided.

[0039] The material guiding device 9 includes a liquid changing box body 99 for support. At the side end face of the liquid changing box body 99 near the upper part, a third one-way valve 98 is provided, and a sealing guide seat 97 is fixedly arranged at the center of the upper end face of the liquid changing box body 99. At the center of the upper end face of the sealing guide seat 97, a second one-way valve 96 is fixedly arranged. At the side part of the inner end face of the liquid changing box body 99, a driving chuck 93 is rotationally clamped, and a second synchronous pulley 92 is arranged at the center of the side end face of the driving chuck 93 away from the third one-way valve 98. Inside the side end face of the driving chuck 93, a fixed shifting shaft 94 is provided. The inner end face of the liquid changing box body 99 is slidably clamped with a sealing sliding seat 95 through the fixed shifting shaft 94, and a support guiding groove 91 is provided at the center of the side end face of the sealing sliding seat 95.

[0040] The positioning guide seat 25 is slidably clamped inside the filtering box body 210 through the adaptation of the guiding sliding groove 28 and the fixed guiding shaft 23, and the cam sliding groove 21 and the guiding sliding shaft 27. When adsorbing and filtering the cleaning liquid inside the filtering box body 210, through the adaptation of the cam sliding groove 21 and the guiding sliding shaft 27, the fixed guiding shaft 23 can cyclically drive the two groups of positioning guide seats 25 and the filtering and adsorbing plates 26 to cyclically filter and adsorb the cleaning liquid inside the filtering box body 210.

[0041] The transmission worm 32 is meshed and connected with the driving worm gear 29, and the first synchronous pulley 31 is meshed and connected with the first synchronous pulley 5 through the first synchronous belt 4, which can effectively improve the transmission stability of the subsequent equipment and also improve the power utilization efficiency of the equipment.

[0042] The first one-way valve 212 is connected to the ultrasonic cleaning machine body 1 through a liquid guiding pipe 211 in a through manner. Two groups of second synchronous belt pulleys 92 are meshed with the second synchronous belt 8. When the cleaning liquid in the filter box body 210 is filtered and adsorbed to the top, the first one-way valve 212 can be opened to automatically export the upper clear liquid through the liquid guiding pipe 211, improving the efficiency of subsequent filtration and adsorption of the cleaning liquid.

[0043] The transmission chuck 93 is adapted to the support guide groove 91 through a fixed shifting shaft 94, thereby driving the sealing sliding seat 95 to reciprocate inside the liquid changing box body 99. When circulating and exporting the cleaning liquid inside the ultrasonic cleaning machine body 1, the transmission chuck 93 can drive the sealing sliding seat 95 to move up and down inside the liquid changing box body 99 in a circulating manner through the sliding limit of the fixed shifting shaft 94 and the support guide groove 91, so that a circulating negative pressure is generated inside the liquid changing box body 99 to adsorb the cleaning liquid inside the ultrasonic cleaning machine body 1. At the same time, when moving upward, the cleaning liquid is introduced into the filter box body 210 through the third one-way valve 98 under positive pressure for filtration.

[0044] Working principle: Before use, the staff can introduce the cleaning liquid and various workpieces to be cleaned into the interior of the ultrasonic cleaning machine body 1, thus facilitating subsequent cyclic cleaning operations. After the ultrasonic cleaning machine body 1 has cleaned the workpieces for a period of time, the cleaning liquid contains impurities of various workpieces. At this time, the staff can start the servo motor 7, and the servo motor 7 can drive the second synchronous pulley 92 and the first synchronous pulley 5 to rotate synchronously. When the second synchronous pulley 92 rotates, the second synchronous pulley 92 can synchronously drive another set of second synchronous pulleys 92 through the second synchronous belt 8. The two sets of second synchronous pulleys 92 can synchronously drive the transmission chuck 93 and the fixed dial shaft 94 to rotate. When the fixed dial shaft 94 rotates in a circular motion, it can drive the sealing slide seat 95 to perform cyclic up and down displacement inside the liquid changing box 99 through the sliding fit with the support guide groove 91. When the sealing slide seat 95 moves downward inside the liquid changing box 99, the inside of the liquid changing box 99 is in a negative pressure state, and the cleaning liquid inside the ultrasonic cleaning machine body 1 can be adsorbed into the liquid changing box 99 through the second one-way valve 96. Subsequently, when the sealing slide seat 95 moves upward, the second one-way valve 96 closes, and the sealing slide seat 95 can unidirectionally introduce the cleaning liquid into the filter box 210 through the third one-way valve 98, thus completing the feeding operation of an equal amount of cleaning liquid. At this time, the first synchronous pulley 5 that rotates synchronously with the second synchronous pulley 92 can drive the first synchronous pulley 31 to rotate through the first synchronous belt 4, and the first synchronous pulley 31 can drive the transmission worm 32 to rotate through the transmission guide shaft 34. At the same time, the transmission worm 32 can drive the transmission card shaft 22 and the two fixed guide shafts 23 to rotate synchronously through the meshing with the transmission worm gear 29. The two fixed guide shafts 23 can drive the two positioning guide seats 25 and the filter adsorption plates 26 to perform cyclic reciprocating displacement through the sliding limit of the cam chute 21 and the guide slide shaft 27. While the multiple filter adsorption plates 26 reciprocate, they can synchronously filter and adsorb various impurities in the cleaning liquid inside the filter box 210 in all directions. After multiple adsorptions, when the cleaning liquid inside the filter box 210 reaches the top, at this time, the upper-layer cleaning liquid in the filter box 210 is unidirectionally introduced into the ultrasonic cleaning machine body 1 again through the first one-way valve 212 and the liquid guide pipe 211 under the action of pressure, completing the recycling.

[0045] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made in these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
