Problems solved by technology

For the above occasions, currently only two sprayers can be used to store and spray liquid A and liquid B respectively. During operation, both hands need to hold the sprayer at the same time to spray, which is not only complicated to operate, but also cannot achieve good mixing and use effects

Embodiment 1

[0032] combine Figure 1 to Figure 4 As shown, the present embodiment provides a pressing switching mechanism, including a body 1, on which a first spray head 2, a second spray head 3 and a switching mechanism are provided. The switching mechanism includes an active part, an intermittent movement part, a first pressing part 6 and the second pressing part 7, the active part can drive the intermittent moving part to perform intermittent movement, the intermittent moving part is connected with the first pressing part 6 and the second pressing part 7 respectively, and the intermittent moving part can drive the first pressing part in the state of intermittent motion The piece 6 and the second pressing piece 7 press the first spray head 2 and the second spray head 3 in sequence.

[0033] The main body 1 is used to cooperate with the bottle body to form a closed liquid storage space, and its specific structure is not strictly limited. For example, it can be set as a cover body with i...

Embodiment 2

[0047] combine Figure 1 to Figure 4 As shown, the present embodiment provides a nebulizer, including a bottle body and the push switching mechanism of Embodiment 1. The bottle body has a first chamber and a second chamber separated from each other, and the body 1 of the push switch mechanism is covered on the bottle body. The first suction pipe and the second suction pipe connected with the first spray head 2 and the second spray head 3 are respectively inserted in the first cavity and the second cavity.

[0048] The bottle body is used to store two different liquids, and the two liquids are stored in the first cavity and the second cavity of the bottle body respectively; there are no strict restrictions on the structure and size of the bottle body, and can be reasonably set according to actual needs.

[0049] The sprayer of this embodiment is equipped with the push switching mechanism of Embodiment 1, which can store two different liquids, and realize the spraying and unifor...

Embodiment 3

[0051] This embodiment provides a spray device for digesting nucleic acid contamination, including the sprayer of Embodiment 2, liquid A is installed in the first cavity, and liquid B is installed in the second cavity; wherein, the liquid A can have a mass content of 0.2 -0.4% hydrogen peroxide solution, liquid B can be a mixed solution of metal ions and buffer, the concentration of metal ions in the mixed solution is 0.5-1.5mM, the concentration of buffer is 3-5mM, the pH of the mixed solution is 7.0-8.0.

[0052] More specifically, in one embodiment, liquid A is a hydrogen peroxide solution with a mass content of 0.3%, and liquid B is CuSO 4 and Tris mixed solution, CuSO in the mixed solution 4 The concentration of Tris was 1 mM, the concentration of Tris was 4 mM, and the pH value of the mixed solution was 7.5.

[0053] Use ultrapure water to dilute the 30% hydrogen peroxide mother solution to a mass concentration of 0.3%, that is, add 99 parts of ultrapure water to 1 par...

Abstract

The invention provides a pressing switching mechanism and a sprayer comprising the pressing switching mechanism and application thereof. The pressing switching mechanism comprises a main body, a firstspray head, a second spray head and a switching mechanism are arranged on the main body, the switching mechanism comprises a driving part, an intermittent moving part, a first pressing part and a second pressing part, the driving part can drive the intermittent moving part to move intermittently, the intermittent moving part is connected with the first pressing part and the second pressing part respectively, and the intermittent moving part can drive the first pressing part and the second pressing part to press the first spray head and the second spray head in sequence in an intermittent moving state. The sprayer provided with the pressing switching mechanism can conveniently and quickly achieve spraying and mixing of two different liquids, so that the time is saved, the efficiency is improved, and good mixing and use effects can be achieved.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a press switch mechanism, a sprayer containing the press switch mechanism and applications thereof. Background technique [0002] A sprayer is a device that uses air suction to turn a liquid into a mist and then sprays it evenly on other objects. It usually consists of an air compression device, a straw, a nozzle, etc. At present, most sprayers on the market use a single nozzle for spraying, which can only be used for one liquid, but cannot use two different liquids at the same time, and cannot realize the mixing of the two liquids at the moment of spraying. [0003] In some occasions, it is necessary to carry out mixed spraying of two or more solutions. Before the two solutions are sprayed, the two solutions are independent of each other so as not to affect and pollute each other. For example, when spraying nucleic acid cleaning solution to degrade nucleic acid, it...
