Description
Technical Field
[0001] The invention belongs to the technical field of microorganism oscillation, and in particular relates to an oscillation device for detecting microorganisms in cosmetic samples. Background Art
[0002] The oscillation equipment used to test microorganisms in cosmetic samples is mainly a microbial oscillator, which generates oscillations and disperses the microorganisms in the sample as evenly as possible in the culture medium.
[0003] The oscillation equipment for testing microorganisms in cosmetic samples in the prior art usually adopts the cooperation of an up-and-down oscillation structure and a lateral oscillation structure during use. The cooperation of the two sets of power equipment realizes the oscillation processing of the culture dish on the shaker seat. However, on the one hand, the two sets of oscillation actions require the cooperation of two sets of power equipment. On the other hand, the oscillation direction is only up-and-down and lateral. Although it has a certain oscillation effect, due to the fixed and limited oscillation direction, there are still certain oscillation dead angles in the actual oscillation process, which makes the microorganisms in the culture dish partially unevenly distributed and unable to be oscillated, and the actual oscillation effect is limited.
[0004] In addition, the oscillation equipment for testing microorganisms in cosmetic samples in the prior art needs to maintain sufficient oxygen supply to the microorganisms while promoting the dispersion of the microorganisms during the oscillation process. However, in the current oscillation process, two methods are used for the culture dish: open or closed. The former requires strict control of the oscillation and there is sputtering wind direction.

As the cam 41 rotates, its protrusion changes the contact direction and angle, and the squeezing and pushing intermediate cylinder 31 synchronously reverses, and drives the placement table 2 fixed on the top to shake, and as the cam 41 continues to rotate, the oscillation assembly 3 dynamically deflects downward along the trajectory from the left direction, and the placement table 2 follows the action. When the raised portion of the cam 41 rotates to the other side and is aligned with the inner principle of the intermediate tube 31, the intermediate tube 31 is elastically reset by means of a spring 34, completing the oscillation of the arc trajectory, so that the placement table 2 oscillates in the direction of the arc trajectory, so that the microorganisms in the culture dish assembly 8 are fully and evenly distributed; during the oscillation process, the air supply assembly 6 is started, and the air pump 61 inputs pressurized air into the connecting cover 62, and inputs it into the curved hole 43 of the rotating sleeve connecting shaft 42, and is blown out through the connecting port 44, and when the cam 41 rotates to the right horizontally, at this time, the oscillation assembly 3 does not contact the cam 41, and the placement table 2 is reset to maintain stability and is in a non-oscillating action state, at this time, the connecting port 44 on the cam 41 and the conducting port in the bypass assembly 7 72 is connected, and the pressurized air is input into the distribution component 11 through the fixed cover 1 73, the middle tube 75 and the fixed cover 2 74, and the pressurized air entering the distribution component 11 enters the sleeve 94 of the limiting component 9 through the middle frame 111 and the through hole 113, and pushes the push rod 93 to move upward, while stretching the spring three 95, the top plate 91 drives the pressure rod 92 to move upward, so that the cover body 82 loses the top compression effect and moves upward under the elastic action of the spring two 84, opening the disk body 81, and the inside of the disk body 81 is connected with the environment, and oxygen enters. As the oscillation reciprocates, the disk body 81 is automatically opened to replenish oxygen when an oscillation cycle of the placement table 2 ends and stabilizes, and the disk body 81 is sealed during the oscillation action.
