It has the advantages of low noise, uniform mixing, and convenience.
[0003] However, existing shakers still have certain defects in use, especially for shakers that require manual pressing of test tubes onto the shaking medium. Since the shaking medium is usually placed on the output shaft of the shaker, the output shaft of the shaker often separates from the shaking medium during the shaking process. Secondly, the output shaft of the shaker is usually provided with a groove, which is prone to dust accumulation over time. Utility Model Content

[0014] The beneficial effects of this utility model are:
[0015] 1. This utility model, through the setting of a rubber plate and a snap-fit air bladder, causes the center of the rubber plate to descend when the test tube or volumetric flask is pressed down. During this process, the air in the empty groove is squeezed and compressed into the snap-fit air bladder, which then expands. After expansion, the snap-fit air bladder snaps into the slot, effectively reinforcing the rubber plate and helping to avoid the risk of the rubber plate being shaken off during the shaking of the test tube or volumetric flask.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0026] A protective component for a small shaking device, such as Figures 1-6 As shown, its structural relationship is as follows: it includes a vibrating device body 1, a vibration motor 5 is fixedly connected inside the vibrating device body 1, an output shaft 6 is fixedly connected to the vibration motor 5, a rubber plate 2 is snapped onto the end of the output shaft 6 away from the vibration motor 5, a slot 11 is opened on the outer side of the end of the output shaft 6 away from the vibration motor 5, and a snap-fit airbag 12 is provided at the bottom of the rubber plate 2, and the snap-fit airbag 12 is snapped into the slot 11.
[0027] In practice, the vibration motor 5 transmits vibration to the rubber plate 2 through the output shaft 6.
[0028] As a further embodiment of this utility model, a sliding sleeve is fixedly connected to the bottom of the rubber plate 2, and the snap-fit airbag 12 is embedded in the inner wall plate at the bottom end of the sliding sleeve. A partition is provided in the middle section of the sliding sleeve, and a slot 15 is provided at the top of the partition. A hollow layer is opened inside the rubber plate 2, and the slot 15 is connected to the hollow layer. Both sides of the slot 15 are connected to a connecting air pipe 13, and the end of the connecting air pipe 13 away from the slot 15 is connected to the snap-fit airbag 12.
[0029] In practice, the snap-fit airbag 12 effectively reinforces the rubber plate 2 during the shaking of test tubes or volumetric flasks.
[0030] As a further embodiment of this utility model, a spring 10 is fixedly connected inside the slot 15. The two ends of the spring 10 are respectively fixedly connected to the top wall of the partition and the inner top wall of the hollow layer opened on the rubber plate 2. A plurality of rubber columns 14 for support are fixedly connected inside the hollow layer of the rubber plate 2.
[0031] In practice, the rubber column 14 is used to improve the stability of the rubber plate 2.
[0032] As a further embodiment of this utility model, the vibrator body 1 is provided with four rectangular sliding grooves 19, and a slider 22 is slidably connected in the rectangular sliding grooves 19. A sliding column 21 is fixedly connected to the top of the slider 22. The sliding column 21 passes through the top wall panel of the vibrator body 1, and a rectangular ring-shaped rubber guardrail 3 is fixedly connected to the top of the sliding column 21. The four sliding columns 21 are respectively fixedly connected to the bottom of the four corners of the rubber guardrail 3.
[0033] In practice, the rubber guardrail 3 can protect the rubber plate 2 and effectively shield the rubber plate 2 when it is shaken off.
[0034] As a further embodiment of this utility model, the bottom of the rectangular slide 19 is connected to a connecting pipe 7. There are four connecting pipes 7 in total, which are used to connect the four rectangular slides 19 to each other. The ends of two rectangular slides 19 away from the connecting pipe 7 are connected to a solenoid valve 20. The ends of the solenoid valve 20 away from the rectangular slide 19 are connected to the outside atmosphere.
[0035] In practice, when the gas in the first airbag 8 and the second airbag 9 decreases, the rubber guardrail 3 is pulled upwards, and then the solenoid valve 20 is opened, allowing air from the outside atmosphere to enter the rectangular slide 19. Then the rubber guardrail 3 is pressed down, allowing the gas in the rectangular slide 19 to enter the first airbag 8 and the second airbag 9, thus replenishing the gas in both.
[0036] As a further embodiment of this utility model, a circular groove is provided at the top center of the shaking device body 1, the rubber plate 2 is located directly above the circular groove, the bottom of the circular groove is embedded with a first airbag 8, the top inner wall plate of the circular groove is embedded with a second airbag 9, the top of the two connecting pipes 7 located on both sides of the shaking device body 1 are connected to an internal vertical pipe, and the end of the internal vertical pipe away from the connecting pipe 7 is connected to the first airbag 8 and the second airbag 9 respectively.
[0037] In practice, the second airbag 9 is used to seal the circular groove.
[0038] As a further embodiment of this utility model, the end of the built-in vertical tube away from the connecting tube 7 is connected to an electromagnetic three-way valve 17. The electromagnetic three-way valve 17 is a three-way valve with one inlet and two outlets. Its input end is connected to the built-in vertical tube, and its two output tubes are respectively connected to the second output tube 16 and the first output tube 18. The second output tube 16 is connected to the second airbag 9, and the first output tube 18 is connected to the first airbag 8.
[0039] In practice, under normal conditions, the electromagnetic three-way valve 17 connects the built-in vertical pipe to the second output pipe 16. Only when cleaning the dust inside the circular groove will the electromagnetic three-way valve 17 connect the built-in vertical pipe to the first output pipe 18.
[0040] As a further embodiment of this utility model, the top of the rectangular slide groove 19 is threaded with a fixing knob 4, which is in movable contact with the slider 22. The fixing knob 4 is used to fix the slider 22.
[0041] In practice, the fixing knob 4 abuts against the slider 22. When the rubber guardrail 3 moves to its highest position, the center of the fixing knob 4 and the side of the slider 22 are on the same horizontal plane. The technique of fixing the slider 22 with the fixing knob 4 is existing technology and will not be disclosed in detail here.
[0042] In use, the rubber guardrail 3 is first pulled to cover the outside of the rubber plate 2. Then, the fixing knob 4 is turned to make the fixing knob 4 abut against the slider 22, thereby fixing the slider 22 and effectively supporting the rubber guardrail 3. Then, the rubber plate 2 is placed on the output shaft 6.
[0043] After placing the rubber plate 2 on the output shaft 6, the technician holds a test tube or volumetric flask and places it on the rubber plate 2. By pressing down on the test tube or volumetric flask, the center of the rubber plate 2 descends. During this process, the air in the empty slot 15 is compressed and forced into the locking airbag 12, causing the locking airbag 12 to inflate. After the locking airbag 12 inflates, it locks into the locking slot 11, effectively reinforcing the rubber plate 2 and preventing the risk of it falling off during shaking of the test tube or volumetric flask. The rubber column 14 and spring 10 effectively allow the rubber plate 2 to recover. After the rubber plate 2 recovers, the locking airbag 12 contracts, allowing the rubber plate 2 to be quickly removed.
[0044] As the slider 22 rises, the cavity space inside the rectangular groove 19 located below the slider 22 increases, allowing gas from the second airbag 9 to enter the cavity below the slider 22. This causes the second airbag 9 to contract, opening the circular groove and allowing the rubber plate 2 to be effectively placed on top of the output shaft 6. Similarly, when the rubber guardrail 3 falls, the cavity space inside the rectangular groove 19 located below the slider 22 decreases, causing the second airbag 9 to expand and seal the top of the circular groove. This helps prevent dust from accumulating in the groove when the device is not in use and also provides some dust protection for the output shaft 6.
[0045] By controlling the electromagnetic three-way valve 17 to connect the built-in vertical pipe to the first output pipe 18, and then by pulling the rubber guardrail 3 up and down, the cavity space inside the rectangular slide groove 19 located below the slider 22 changes continuously, thereby causing the first airbag 8 to be in a state of continuous contraction and expansion, so that the dust entering the circular groove can be shaken off by the contraction and expansion of the first airbag 8.
[0046] During use, before shaking off the dust inside the circular groove, the rubber guardrail 3 needs to be pulled upward to cause the second airbag 9 to contract. Then, the electromagnetic three-way valve 17 is controlled to connect the built-in vertical pipe to the first output pipe 18.
