Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment, and more specifically, to an ultrasonic cleaner. Background Technology

[0002] An ultrasonic cleaner is a mechanical device that uses high-frequency ultrasonic vibrations to clean. Ultrasonic cleaners remove dirt from the surface of objects by utilizing the enormous energy generated by the bursting of bubbles in a liquid.

[0003] Chinese Patent Publication No. CN210907176U discloses a high-efficiency ultrasonic cleaner. Its key technical features include: a body, characterized in that the body is equipped with a control panel and a cleaning tank; the cleaner also includes a shelf, which comprises an annular plate; multiple fixing rods are fixedly connected to the lower part of the annular plate; a first filter screen is fixedly connected to the bottom of the multiple fixing rods; multiple matching slots are provided at equal intervals on each of the multiple fixing rods; and a second filter screen is connected to the multiple fixing rods through the slots.

[0004] The above solution addresses the problem that existing shelves are mostly single-layered, causing items to pile up and making them difficult to clean. However, when the shelves are placed in the cleaning tank, there is no medium to fix them in place. When the ultrasonic cleaner is running, the shelves will vibrate due to the vibration of the liquid, causing them to collide with the inner wall of the cleaning tank, which can easily damage the inner wall of the cleaning tank.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an ultrasonic cleaner.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an ultrasonic cleaner, including a body, a cleaning tank on the body, a shelf for placing items in the cleaning tank, the shelf including an annular plate and several fixing rods fixed below the annular plate, a filter screen fixed to the end of the fixing rod away from the annular plate, a limiting component for limiting the annular plate on the body, several limiting rods for abutting against the inner wall of the cleaning tank on the fixing rods, and a rubber block fixed to the end of the limiting rod facing away from the fixing rod.

[0008] The present invention is further configured such that: a square hole is provided on the annular plate, and the limiting component includes a connecting block fixed on the machine body and a pressing block rotatably connected to the connecting block; the pressing block can pass through the square hole and press the annular plate against the machine body.

[0009] The present invention is further configured such that: a threaded hole is provided on the machine body, a through hole is provided on the clamping block, a bolt passes through the through hole, and one end of the bolt is threadedly connected to the threaded hole.

[0010] The present invention is further configured such that the area of ​​the square hole is greater than the cross-sectional area of ​​the pressing block.

[0011] The present invention is further configured such that: the number of clamping blocks is two, and the two clamping blocks are respectively arranged on two opposite sides of the machine body.

[0012] The present invention is further configured such that a rubber sheet is attached to the side wall of the clamping block that is used to abut against the annular plate.

[0013] The present invention is further configured such that the cleaning tank is made of stainless steel.

[0014] In summary, this utility model has the following beneficial effects: After people place the items to be cleaned on the shelf, the limiting rod is slid into the inner wall of the cleaning tank. At this time, the rubber block can effectively prevent hard contact between the limiting rod and the inner wall of the cleaning tank, and can effectively prevent the inner wall of the cleaning tank from being scratched. When the bottom of the annular plate contacts the machine body, the limiting component is used to restrict the annular plate to the machine body. At this point, the limiting of the shelf is completed. After the ultrasonic cleaner is started, the vertical movement of the shelf is restricted by the limiting component. The rubber block and the limiting rod can effectively separate the fixing rod from the inner wall of the cleaning tank. At the same time, the contact between the rubber block and the inner wall of the cleaning tank can effectively alleviate the resonance between the shelf and the machine body caused by the ultrasonic operation, reduce the possibility of damage to the cleaning tank caused by the collision between the shelf and the inner wall of the cleaning tank, and effectively improve the service life of the shelf and the cleaning tank.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] Ultrasonic cleaners, such as Figure 1 and Figure 2 As shown, the device includes a body 1, a cleaning tank 2 on the body 1, and a shelf for placing items in the cleaning tank 2. The shelf includes an annular plate 3 and several fixing rods 4 fixed below the annular plate 3. A filter screen 5 is fixed to the end of the fixing rod 4 away from the annular plate 3. The body 1 is equipped with a limiting component for restricting the annular plate 3. Several limiting rods 6 are provided on the fixing rods 4 for contacting the inner wall of the cleaning tank 2. A rubber block 7 is attached to the end of the limiting rod 6 facing away from the fixing rod 4. After the items to be cleaned are placed on the shelf, the limiting rod 6 is slid into the inner wall of the cleaning tank 2. At this time, the rubber block 7 can effectively prevent the limiting rod 6 from hardly contacting the inner wall of the cleaning tank. The contact effectively prevents scratches on the inner wall of the cleaning tank. When the bottom of the annular plate 3 contacts the body 1, the limiting component restricts the annular plate 3 to the body 1. At this point, the limiting of the shelf is completed. After the ultrasonic cleaner is started, the vertical movement of the shelf is restricted by the limiting component. The rubber block 7 and the limiting rod 6 can effectively separate the fixing rod 4 from the inner wall of the cleaning tank 2. At the same time, the contact between the rubber block 7 and the inner wall of the cleaning tank 2 can effectively alleviate the resonance between the shelf and the body 1 caused by the ultrasonic operation, reduce the possibility of damage to the cleaning tank caused by the collision between the shelf and the inner wall of the cleaning tank, and effectively improve the service life of the shelf and the cleaning tank 2.

[0022] like Figures 2 to 4As shown, the annular plate 3 has a square hole 8. The limiting component includes a connecting block 9 welded to the body 1 and a clamping block 10 rotatably connected to the connecting block 9. The movable end of the clamping block 10 can be flipped toward the outer edge of the body 1. The clamping block 10 can pass through the square hole 8 and press the annular plate 3 against the body 1. When placing the shelf in the washing tank 2, it is necessary to ensure that the clamping block 10 is flipped so that its projection surface coincides with the connecting block 9. Then, after aligning the square hole 8 with the clamping block 10, the annular plate 3 is pressed against the body 1. Then, the clamping block 10 is rotated to press the annular plate 3 against the body 1. The body 1 has a threaded hole 11, and the clamping block 10 has a through hole 12. A bolt 14 passes through the through hole 12, and one end of the bolt 14 is threadedly connected to the screw thread. In the hole 11, the other end of the bolt 14 is provided with a butterfly screw head. After the annular plate 3 is pressed against the machine body 1 by the clamping block 10, one end of the bolt 14 is passed through the through hole 12 and screwed into the threaded hole 11. The clamping block 10 is pressed against the annular plate 3 by the threaded connection, so that when the ultrasonic cleaner is used later, the clamping block 10 is not likely to lose its restraining effect on the annular plate 3 due to vibration. The butterfly screw head provided on the bolt 14 provides a better point of force for people to complete the installation and removal of the bolt 14. The area of ​​the square hole 8 is larger than the cross-sectional area of ​​the clamping block 10. This setting allows people to align the inner wall of the square hole 8 with the clamping block 10 without spending too much time when inserting the square hole 8 into the clamping block 10, so that people can complete the restraint of the clamping block 10 more quickly.

[0023] like Figure 1 and Figure 2 As shown, there are two clamping blocks 10, which are respectively set on two opposite sides of the body 1. This arrangement allows the shelf to be limited simply by rotating the two clamping blocks 10 and fixing them with bolts 14. The clamping blocks 10 fixed on opposite sides can provide good clamping force to the annular plate 3, thereby effectively restricting the shelf. Rubber sheets 13 are attached to the side wall of the clamping block 10 that abuts against the annular plate 3. During the process of screwing the bolts 14 into the threaded holes 11, the wing-shaped screw head abuts against the clamping block 10 and applies pressure. The clamping block 10 applies pressure, which is transmitted to the rubber sheet 13 through the clamping block 10. This pressure forces the rubber sheet 13 to deform and press the annular plate 3 against the machine body 1. The clamping block 10 and the annular plate 3 are separated by the rubber sheet 13, which effectively avoids rigid contact between the clamping block 10 and the annular plate 3, thus better protecting the annular plate 3. The cleaning tank 2 is made of stainless steel. The good chemical stability of stainless steel allows the cleaning tank 2 to adapt well to the liquid-filled environment, thus effectively extending the service life of the cleaning tank 2.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
