Description

Technical Field

[0001] The invention relates to the technical field of mosquito experimental tools, in particular to a mosquito hatching device. Background Art

[0002] In the mosquito research in the laboratory, the mosquitoes' disease resistance, reproduction ability, virus carrying ability and other abilities are studied. The laboratory will continue to hatch and breed mosquitoes while consuming the mosquito research. Existing results include that the eggs laid by the bred mosquitoes cannot develop into young mosquitoes, ultimately achieving the goal of combating the spread of diseases such as dengue fever and Zika virus.

[0003] The hatching of mosquitoes needs to be carried out in water. The existing mosquito hatching is carried out in an incubation device filled with water. During the mosquito hatching process, there will be a certain time difference in the hatching of mosquitoes, resulting in some mosquitoes hatching first and the other part hatching later. The hatched mosquitoes will cause the internal space to shrink. The density of hatched mosquitoes is too large to interfere with the unhatched mosquitoes. The volume of the incubation device is fixed. At this time, the hatched mosquitoes need to be drained. The existing incubation device drains the internal mosquitoes and water through the valve body switch of the lower pipe, but the valve body will also squeeze and cause the death loss of mosquitoes during closing, increasing the loss in mosquito reproduction.

When the inner piston member 404 moves closer to the outer piston tube 402, the outer piston tube 402 and the middle connecting tube 401 remain closed. The inner piston member 404 compresses the internal gas of the outer piston tube 402 and discharges it from the upper one-way exhaust port 403, and the internal air of the middle connecting tube 401 and the inverted U-shaped guide tube 4 is extracted. The middle connecting tube 401 and the inverted U-shaped guide tube 4 are filled with liquid, thereby realizing the connection of the liquid levels at both ends of the inverted U-shaped guide tubes 4 on both sides, and performing the diversion operation of mosquitoes inside the expanded sub-box 102. There is no need to set a valve body, thereby avoiding the situation where mosquitoes remain due to the valve body switch.

[0042] The working principle of this embodiment is as follows: water is poured into the space formed by the main incubation box 1, the extension sub-box 102 and the inner corrugated telescopic frame 101, and the test paper with mosquito eggs is placed in the water inside the space formed by the main incubation box 1, the extension sub-box 102 and the inner corrugated telescopic frame 101, and then the upper cover plate 2 slides horizontally in the top slide frame of the main incubation box 1, and the upper cover plate 2 pushes the extension cover plate 201 to move to the top of the extension sub-box 102 at the same time, and the positioning bracket 202 and the upper block 109 at the head end of the extension cover plate 201 slide, and the positioning bracket 202 The lower part of the head end moves upward along the top of the upper clamping block 109, and the positioning bracket 202 moves to the other side of the upper clamping block 109. The vertical surface of the upper clamping block 109 fits with the vertical surface in the middle of the positioning bracket 202, completing the clamping and fixing operation of the positioning bracket 202 and the upper clamping block 109. The position of the extension cover 201 and the extension sub-box 102 is fixed. The upper cover 2 and the extension cover 201 block the extension sub-box 102 and the main incubation box 1 into a closed box. The main incubation box 1 can heat the internal water through the electric heating tube 107.

[0043] The main incubation box 1 and the extended sub-box 102 slide away from each other, and the main incubation box 1 and the extended sub-box 102 simultaneously pull the inner corrugated telescopic frame 101 in the middle to extend synchronously, and the side connecting slide tube 103 and the side connecting slide column 104 slide away, and the upper connecting column 105 moves synchronously with the side connecting slide column 104, and the tightening nut 106 moves along the thread of the upper connecting column 105 to tighten the side connecting slide tube 103, so as to fix the position between the side connecting slide tube 103 and the side connecting slide column 104, and fix the position between the main incubation box 1 and the extended sub-box 102, and the main incubation box 1 and the extended sub-box 102 are fixed.

The main incubation box 1 and the extended sub-box 102 adjust the internal space according to the number of hatched mosquitoes. When there are more hatched mosquitoes, they are expanded to avoid the hatched mosquitoes affecting the unhatched ones. The upper cover 2 and the extended cover 201 move synchronously with the main incubation box 1 and the extended sub-box 102 to ensure the covering and sealing.

[0045] The air-permeable grid 203 performs ventilation operation inside the main incubation box 1. When there are flying adults in the main incubation box 1 in advance, the air-permeable grid 203 is slid to the outside of the upper cover 2. The through hole in the middle of the upper cover 2 exposes a channel connecting the main incubation box 1 and the extended sub-box 102, which is convenient for leading out the adults that have developed in advance inside the main incubation box 1 and the extended sub-box 102. The adults fly out through the channel or are connected to the subsequent adult breeding device through a pipeline. When it is necessary to perform a diversion operation on the hatched mosquitoes inside the main incubation box 1, one end of the inverted U-shaped guide pipe 4 is below the water inside the extended sub-box 102, and the other end of the inverted U-shaped guide pipe 4 is in another container. Below the liquid level, the inner piston member 404 pulls the central connecting tube 401 and the inverted U-shaped guide tube 4 to inhale air, and the inner piston member 404 compresses the internal gas of the outer piston tube 402 to be discharged from the upper one-way exhaust port 403, and the internal air of the central connecting tube 401 and the inverted U-shaped guide tube 4 is extracted, and the interior of the central connecting tube 401 and the inverted U-shaped guide tube 4 is filled with liquid, thereby realizing the connection of the liquid levels at both ends of the inverted U-shaped guide tubes 4 on both sides, facilitating the diversion operation of the mosquitoes inside the expanded sub-box 102, and the inverted U-shaped guide tube 4 moves upward and separates from the internal liquid level of the main incubation box 1 to perform the diversion disconnection operation, without the need for the setting of a valve body, avoiding the situation where mosquitoes remain due to the valve body switch, and reducing the loss of mosquito hatching and reproduction.
