[0023] The present utility model will be further described below with reference to the accompanying drawings through specific embodiments, but it is not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present invention.
[0024] An ultrasonic cleaning machine described in this embodiment is as Figure 1 , Figure 2 , Figure 3 and Figure 5 shown, and includes an ultrasonic cleaning machine body 1. A liquid collecting tank 2 is provided at the top of the ultrasonic cleaning machine body 1. The liquid collecting tank 2 is of a rectangular structure and is made of stainless steel. A cleaning basket 3 is independently arranged in the liquid collecting tank 2. The cleaning basket 3 is made of plastic and is of a mesh shape to allow the cleaning liquid to flow through. The cleaning basket 3, the liquid collecting tank 2, and the ultrasonic cleaning machine body 1 are all structures of existing ultrasonic cleaning machines.
[0025] A support rod for suspending the bottle is arranged in the cleaning basket 3. A first ring 7 and a second ring 10 are independently sleeved on the support rod. The first ring 7 and the second ring 10 are of the same size. The outer diameters of the first ring 7 and the second ring 10 are smaller than the inner diameter of the bottle or beaker. The thicknesses of the first ring 7 and the second ring 10 are relatively thin, which can reduce the contact area between the first ring 7 and the second ring 10 and instruments such as bottles or beakers. The support rod is connected to the cleaning basket 3 through a connecting piece 12.
[0026] As Figure 1 and Figure 4 shown, the connecting piece 12 is of a "C" - shaped structure. A fixed tube 11 is fixed to one side wall of the connecting piece 12. The connecting piece 12 includes two vertically arranged clamping blocks. The tops of the two clamping blocks are fixed through a connecting block. The distance between the two clamping blocks is not less than the wall thickness of the cleaning basket 3. During use, the connecting piece 12 is inserted into the top of the side wall of the cleaning basket 3, thereby connecting the fixed tube 11 to the cleaning basket 3.
[0027] The support rod includes a fixed column 8 and a fixed tube 11. The diameter of the fixed column 8 is the same as the outer diameter of the fixed tube 11. The first ring 7 is sleeved on the fixed column 8, and the second ring 10 is sleeved on the fixed tube 11.
[0028] A bearing is installed between the first ring 7 and the fixed post 8. The inner ring of the bearing is fixedly sleeved on the fixed post 8, and the outer ring of the bearing is fixed to the inner ring of the first ring 7. The bearing allows the first ring 7 to rotate freely on the fixed post 8 and prevents the first ring 7 from sliding horizontally. This section as a whole constitutes a limiting component for restricting the movement of the first ring 7 along its length direction.
[0029] Of course, in some embodiments, the first limiting component may also include two annular limiting blocks, both of which are fixedly sleeved on the fixing post 8. The first ring 7 is located between the two limiting blocks, and the inner diameter of the first ring 7 is smaller than the outer diameter of the limiting blocks, thereby preventing the sliding of the first ring 7. The second limiting component is the same as the first limiting component, and the second ring 10 is also connected to the fixing tube 11 through a bearing or a limiting block.
[0030] A fixing rod 13 is provided between the eight fixing tubes 11 of the fixing column. The diameter of the fixing rod 13 is smaller than the diameter of the fixing column 8. The fixing rod 13 is fixed to the fixing column 8. The diameter of the fixing rod 13 is smaller than the inner diameter of the fixing tube 11, so that the fixing rod 13 can be inserted into the fixing tube 11. By sliding the fixing rod 13 in the fixing tube 11, the combined length of the fixing rod 13 and the fixing tube 11 can be changed, thereby adjusting the distance between the fixing column 8 and the fixing tube 11, and also adjusting the distance between the first ring 7 and the second ring 10. The distance between the first ring 7 and the second ring 10 can be adjusted according to the height of the bottle or beaker, so that the first ring 7 and the second ring 10 contact the inner wall of the bottle or beaker.
[0031] The top of the fixing tube 11 has a first through hole, and a pin 9 is independently installed in the first through hole. The fixing rod 13 has several grooves along its length for inserting the ends of the pins 9. By inserting the pins 9 into the grooves on the fixing rod 13, the sliding of the fixing rod 13 in the fixing tube 11 is blocked. By inserting them into different grooves, the combined length of the fixing rod 13 and the fixing tube 11 is controlled, thereby adjusting the gap between the fixing post 8 and the fixing tube 11. This section as a whole constitutes a locking device that fixes the fixing rod 13 in the fixing tube 11.
[0032] Of course, in some embodiments, the locking element can also be a bolt, with a threaded hole opened in the side wall of the fixing tube 11, and the bolt thread passes through the threaded hole and presses against the fixing rod 13 to fix the fixing rod 13 inside the fixing tube 11.
[0033] The above three sections together constitute an adjustment assembly for adjusting the gap between the fixed column 8 and the fixed tube 11. Of course, in some embodiments, the adjustment assembly can also be a screw rod 13, with an internal thread on the inner side wall of the fixed tube 11. The gap between the fixed column 8 and the fixed tube 11 can be adjusted by the threaded engagement of the fixed rod 13 and the fixed tube 11.
[0034] The fixing tube 11 is inclined, and its right end is connected to the connector 12. The fixing tube 11 is inclined with its left end higher than its right end. When the fixing tube 11 is located in the cleaning basket 3, since the left end of the fixing tube 11 is lower than the right end, its fixing column 8 and fixing rod 13 are also inclined. Therefore, the horizontal height of the top of the first ring 7 is slightly higher than the horizontal height of the top of the second ring 10. After the bottle or beaker is suspended on the first ring 7 and the second ring 10, the bottle or beaker is inclined. Moreover, the bottle and beaker are fitted on the fixing tube 11, so the bottle mouth is located on the right side. In this way, when the cleaning basket 3 is taken out, the bottle is inclined, which makes it easy for the cleaning liquid in the bottle or beaker to flow out. Of course, it is preferable that the inclination angle is 15 degrees, that is, the angle between the left end of the fixing tube 11 and the top of the cleaning basket 3 is 15 degrees. This allows the cleaning liquid to flow out while avoiding an excessive inclination angle.
[0035] A fixing block is vertically installed on the inner side of the cleaning basket 3. Both ends of the fixing block in the vertical direction are connected to the cleaning basket 3 via connecting blocks. A gap is left between the cleaning basket 3 and the fixing block for the insertion of the side wall of the connecting piece 12. Of course, in actual use, such as... Figure 5 As shown, the right middle part of the cleaning basket 3 protrudes inward, so that the connector 12 is inserted into the protruding part of the cleaning basket 3. This serves two purposes: first, to prevent the connector 12 from contacting the inner wall of the liquid collection tank 2, and second, to prevent the connector 12 from sliding back and forth.
[0036] The inner wall of the cleaning basket 3 is fixed with a box 5, which is a sealed structure. A movable block 16 is independently installed inside the box 5. A guide rod 15 is vertically fixed to the top of the movable block 16. A second through hole for the guide rod 15 to pass through is opened at the top of the box 5. A spring 4 is vertically fixed to the bottom of the movable block 16. In its natural state, the top of the guide rod 15 extends beyond the box 5. A cover plate 6 is installed on the top of the ultrasonic cleaner body 1. The guide rod 15 can be moved downwards by the spring 4. When the cover plate 6 is closed for cleaning, it can compress the spring 4, causing the guide rod 15 to move downwards. The guide rod 15 moves downward to avoid obstructing the closing of the cover plate 6. After the cover plate 6 is opened, the guide rod 15 will not obstruct the opening. The spring 4 will return to its elasticity, causing the guide rod 15 to move upward beyond the top of the collection tank 2. Then, by pinching the guide rod 15, the left end of the cleaning basket 3 is lifted upward, thereby removing the cleaning basket 3 from the collection tank 2. Of course, in order to facilitate the direct removal of the cleaning basket 3 from the collection tank 2, two housings 5 can be provided, located on the left and right sides or the front and back sides of the cleaning basket 3 respectively. The entire contents of this section constitute a portable component that facilitates the removal of the cleaning basket 3 from the collection tank 2.
[0037] Of course, in some embodiments, the portable component may also include a fixing block, the bottom of which is hinged to the top of the cleaning basket 3. When the cover 6 is closed, the fixing block is kept in a horizontal state to avoid affecting the closing of the cover 6. After the cover 6 is opened, the fixing block is swung to a vertical state, and the cleaning basket 3 is lifted out through the fixing block.
[0038] A pull ring 14 is vertically fixed to the top of the guide rod 15. When the bottom of the pull ring 14 contacts the top of the box 5, its cover plate 6 is in the closed state, which can make the height of the top of the box 5 lower than the height of the side wall of the cleaning basket 3. The pull ring 14 allows fingers to be inserted to lift the cleaning basket 3. A sealing ring is provided between the guide rod 15 and the second through hole. The sealing ring is a reciprocating dynamic sealing ring. The sealing ring can prevent the cleaning liquid in the collection tank 2 from entering the box 5 through the gap between the guide rod 15 and the second through hole.
[0039] The working principle and technical effects of this embodiment:
[0040] When cleaning bottles or test tubes, place the bottle or beaker over the outside of the fixing post 8 and fixing tube 11, ensuring the tops of the first ring 7 and the second ring 10 contact the inner wall of the bottle or beaker. Secure the connector 12 to the side wall of the cleaning basket 3, then place the cleaning basket 3 into the collection tank 2, suspending the bottle or beaker within the basket 3 to prevent contact with the bottom. Since the outer walls of the first ring 7 and the second ring 10 are annular, and their diameters are smaller than the inner diameter of the bottle or beaker, the first ring 7 and the second ring 10 only make point contact with the top of the bottle or beaker, resulting in a relatively small contact area. Furthermore, during the cleaning process, the first ring 7 and the second ring 10... All 0 are connected to the fixed column 8 or fixed tube 11 via bearings. When the cleaning fluid is agitated, the first ring 7 and the second ring 10 will agitate, causing the bottle or beaker to shake. This changes the contact points between the first ring 7 and the second ring 10 and the bottle or beaker, resulting in a more thorough cleaning of the bottle or beaker. When the cover plate 6 is closed, the guide rod 15 can be moved downward by the spring 4, thus preventing the guide rod 15 from protruding from the top of the collection tank 2 and obstructing the closing of the cover plate 6. After cleaning, the cover plate 6 is opened, allowing the spring 4 to return to its elasticity, and the guide rod 15 extends beyond the top of the box 5. Then, the cleaning basket 3 is removed from the collection tank 2 by pinching the guide rod 15, avoiding contact with the cleaning fluid in the collection tank 2 and preventing irritation to the skin on the hands.
