Description

Technical Field

[0001] This invention relates to the field of mosquito experimental equipment technology, and in particular to a mosquito hatching device. Background Technology

[0002] In laboratory mosquito research, studies are conducted on mosquitoes' disease resistance, reproductive capacity, and ability to carry viruses. While consuming mosquitoes for research, the laboratory also continuously hatches and breeds them. Existing results, such as the eggs laid by mosquitoes bred through research, cannot develop into larvae, ultimately achieving the goal of combating the spread of diseases such as dengue fever and Zika virus.

[0003] Mosquito hatching requires water to occur. Existing mosquito hatching methods involve a water-filled hatching device. During the hatching process, there is a time difference in the hatching time, resulting in some mosquitoes hatching first and others later. The hatched mosquitoes reduce the internal space, and an excessively high density of hatched mosquitoes can interfere with unhatched mosquitoes. Since the volume of the hatching device is fixed, it is necessary to divert the hatching mosquitoes. Existing hatching devices divert mosquitoes and water through valves in the lower pipes. However, the closing of the valves can also cause squeezing and death of mosquitoes, increasing losses during mosquito reproduction. Summary of the Invention

[0004] This disclosure relates to a mosquito hatching device. A main hatching chamber and an extended auxiliary chamber slide and pull together, with an inner corrugated telescopic frame extending and retracting synchronously to expand and compress the combined space of the main hatching chamber and the extended auxiliary chamber. The main hatching chamber and the extended auxiliary chamber are internally adjusted according to the number of mosquitoes to be hatched, while simultaneously reducing the space occupied by the main hatching chamber and the extended auxiliary chamber. One end of the inverted U-shaped guide tube is below the water level inside the extended auxiliary chamber, and the other end is below the liquid level of another container. The air in the middle of the inverted U-shaped guide tube is sucked out by the cooperation of the outer piston tube and the inner piston, achieving communication between the liquid levels of the two inverted U-shaped guide tubes. This facilitates the diversion of mosquitoes inside the extended auxiliary chamber, eliminating the need for a valve and avoiding the possibility of mosquito residue caused by valve opening and closing.

[0005] In a first aspect, this disclosure provides a mosquito hatching device, specifically comprising: a main hatching chamber, a top cover, a feeding column frame, and an inverted U-shaped guide tube. The top of the main hatching chamber has a horizontally sliding top cover, and a feeding column frame is provided on one side of the top cover. The interior of the main hatching chamber is connected to the first end of the inverted U-shaped guide tube. An inner corrugated telescopic frame with a U-shaped corrugated telescopic structure is fixed to one side of the opening of the main hatching chamber. The tail end of the inner corrugated telescopic frame is fixedly connected to an extended secondary chamber. Side connecting slide tubes are fixed to both sides of the main hatching chamber, and side connecting slide columns are fixed to both sides of the extended secondary chamber. An upper connecting column is fixed to the upper part of the first end of the side connecting slide column, and a tightening nut is screwed onto the upper part of the upper connecting column. An electric heating tube is provided inside the main hatching chamber. A secondary chamber cover is fixedly covered on the top of the extended secondary chamber, and upper locking blocks are fixed to both sides of the secondary chamber cover.

[0006] Furthermore, the side connecting slide tube and the side connecting slide column are horizontally slidably connected, and the upper connecting column slides in the rectangular slide groove at the upper part of the side connecting slide tube. The lower part of the top nut and the top of the side connecting slide tube are in tight contact, making the combined space of the main incubation box, the extended sub-box, and the inner corrugated telescopic frame longer and larger, realizing the expansion and compression of the combined space of the main incubation box and the extended sub-box.

[0007] Furthermore, an extension cover plate is horizontally slidable on one side of the upper cover plate, and positioning brackets are rotatably mounted on both sides of the top of the extension cover plate. A breathable mesh frame is horizontally slidable in the middle of the upper cover plate, and an upper connecting slide tube is fixed in the middle of the extension cover plate. Lower through holes are provided on both sides of the lower part of the upper connecting slide tube.

[0008] Furthermore, the positioning card holder and the upper card block slide into engagement, the first end of the expansion cover plate is attached to the secondary box cover plate, the bottom of the expansion cover plate is slidably attached to the top of the secondary expansion box, the bottom of the upper cover plate is attached to the top of the main incubation box, and the upper cover plate and the expansion cover plate move synchronously with the main incubation box and the secondary expansion box.

[0009] Furthermore, a lower feeding platform is fixed to the lower part of the feeding column frame, and a lower stirring tooth is fixed to the bottom of the lower feeding platform. The rotation of the lower stirring tooth agitates the water inside the main incubation box and the extended auxiliary box, further promoting the spread of the feed to the surrounding area. The feeding column frame and the upper connecting slide tube slide together internally, and the lower feeding platform moves down into the water inside the main incubation box and the extended auxiliary box for feeding.

[0010] Furthermore, the middle part of the inverted U-shaped guide tube is connected to a central connecting pipe, the tail end of the central connecting pipe is connected to the one-way valve at the air inlet end of the outer piston tube, the upper part of the outer piston tube is connected to an upper one-way exhaust port, and an inner piston component slides inside the outer piston tube.

[0011] Furthermore, the inverted U-shaped guide tube and the sub-box cover plate are slidably connected through each other, with the inverted U-shaped guide tube extending into the interior of the extended sub-box, and the inverted U-shaped guide tube and the interior of the extended sub-box being in communication.

[0012] Furthermore, when the inner piston moves away from the outer piston tube, the outer piston tube and the middle connecting tube remain connected; when the inner piston moves closer to the outer piston tube, the outer piston tube and the middle connecting tube remain closed. The inner piston compresses and discharges the gas inside the outer piston tube through the upper one-way exhaust port, extracting the air inside the middle connecting tube and the inverted U-shaped guide tube. The middle connecting tube and the inverted U-shaped guide tube are filled with liquid, realizing the connection of the liquid surfaces at both ends of the two inverted U-shaped guide tubes.

[0013] This invention provides a mosquito hatching device, which has the following beneficial effects:

[0014] The main incubation box and the extended auxiliary box slide and pull the inner corrugated telescopic frame to expand and compress the combined space of the main incubation box and the extended auxiliary box. The main incubation box and the extended auxiliary box are internally adjusted according to the number of mosquitoes hatched, while reducing the space occupied by the main incubation box and the extended auxiliary box.

[0015] As the feeding column moves upward to the lower through-hole, the feeding platform is placed on it. The platform then moves downward into the water inside the main hatching chamber and the extended auxiliary chamber for feeding. Simultaneously, the feeding column seals the lower through-hole to prevent adult insects from escaping. The feeding column, the lower feeding platform, and the lower stirring teeth rotate synchronously in a circular motion. The rotation of the stirring teeth agitates the water inside the main hatching chamber and the extended auxiliary chamber, promoting the spread of the feeding material and facilitating water flow for easy monitoring of the insects.

[0016] The breathable mesh frame slides to the outside of the top cover plate, and the through hole in the middle of the top cover plate exposes a channel connecting the main incubation box and the extended secondary box, which facilitates the extraction of the pre-developed adult insects from inside the main incubation box and the extended secondary box.

[0017] One end of the inverted U-shaped guide tube is below the water level inside the expansion sub-box, and the other end is below the liquid level in another container. By cooperating with the outer piston tube and the inner piston, the air in the middle of the inverted U-shaped guide tube is sucked out, thereby connecting the liquid levels of the two inverted U-shaped guide tubes. This facilitates the diversion of mosquitoes inside the expansion sub-box without the need for a valve body, thus avoiding the situation where mosquitoes remain due to valve opening and closing.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0035] Example 1: Please refer to Figures 1 to 8 :

[0036] This invention proposes a mosquito hatching device, comprising: a main hatching box 1, an upper cover plate 2, a feeding column frame 3, and an inverted U-shaped guide pipe 4. An inner corrugated telescopic frame 101 with a U-shaped corrugated telescopic structure is fixed to one side of the opening of the main hatching box 1. The tail end of the inner corrugated telescopic frame 101 is fixedly connected to the extended secondary box 102. Side connecting slide pipes 103 are fixed to both sides of the main hatching box 1. Side connecting slide columns 104 are fixed to both sides of the extended secondary box 102. An upper connecting column 105 is fixed to the upper part of the first end of the side connecting slide column 104. A tightening nut 106 is screwed to the upper part of the upper connecting column 105. An electric heating tube 107 is provided inside the main hatching box 1. A secondary box cover plate 108 is fixedly covered on the top of the extended secondary box 102. Upper locking blocks 109 are fixed to both sides of the secondary box cover plate 108.

[0037] A top cover plate 2 slides horizontally on the top of the main incubation chamber 1. An extension cover plate 201 slides horizontally on one side of the top cover plate 2. Positioning brackets 202 are rotatably mounted on both sides of the top end of the extension cover plate 201. A breathable mesh frame 203 slides horizontally in the middle of the top cover plate 2. An upper connecting slide tube 204 is fixed in the middle of the extension cover plate 201. Lower through holes 205 are opened on both sides of the lower part of the upper connecting slide tube 204. The positioning brackets 202 and the upper locking block 109 slide and engage. The top end of the extension cover plate 201 is attached to the secondary chamber cover plate 108. The bottom of the extension cover plate 201 slides and is attached to the top of the extension secondary chamber 102. The bottom of the top cover plate 2 is attached to the top of the main incubation chamber 1. The top cover plate 2 and the extension cover plate 201 move synchronously with the main incubation chamber 1 and the extension secondary chamber 102 to ensure a sealed cover. A feeding column 3 is provided on one side of the top cover plate 2. A lower feeding platform is fixed at the bottom of the feeding column 3. 301. The bottom of the lower feeding platform 301 is fixed with a lower stirring tooth 302. The rotation of the lower stirring tooth 302 agitates the water inside the main hatching box 1 and the extended auxiliary box 102, further promoting the spread of the feed. The feeding column 3 and the upper connecting slide tube 204 slide and fit together. The lower feeding platform 301 moves down into the water inside the main hatching box 1 and the extended auxiliary box 102 for feeding. At the same time as the feeding column 3 moves down, the lower through hole 205 is sealed to prevent adult insects from flying out of the lower through hole 205. The inside of the main hatching box 1 is connected to the first end of the inverted U-shaped guide pipe 4. The middle part of the inverted U-shaped guide pipe 4 is connected to the middle connecting pipe 401. The tail end of the middle connecting pipe 401 is connected to the one-way valve at the air inlet end of the outer piston pipe 402. The upper part of the outer piston pipe 402 is connected to the upper one-way exhaust port 403. The inner piston part 404 slides inside the outer piston pipe 402.

[0038] In this embodiment, the side connecting slide tube 103 and the side connecting slide column 104 are horizontally slidably connected, and the upper connecting column 105 slides in the rectangular slide groove on the upper part of the side connecting slide tube 103. The lower part of the top nut 106 and the top of the side connecting slide tube 103 are in tight contact. The combined space of the main hatching box 1, the extended sub-box 102 and the inner corrugated telescopic frame 101 becomes longer and larger, realizing the expansion and compression of the combined space of the main hatching box 1 and the extended sub-box 102. The internal space of the main hatching box 1 and the extended sub-box 102 is adjusted according to the number of mosquitoes hatched. When there are many hatched mosquitoes, the space is expanded to avoid the hatched mosquitoes affecting the unhatched mosquitoes.

[0039] In this embodiment, the inverted U-shaped guide tube 4 and the sub-box cover plate 108 are slidably connected through each other. The inverted U-shaped guide tube 4 extends into the interior of the extended sub-box 102. The inverted U-shaped guide tube 4 and the interior of the extended sub-box 102 are connected. The inverted U-shaped guide tube 4 moves upward and separates from the liquid surface inside the main incubation box 1 to perform a diversion disconnection operation.

[0040] In this embodiment, when the inner piston 404 moves away from the outer piston tube 402, the outer piston tube 402 and the middle connecting pipe 401 remain connected. When the inner piston 404 moves closer to the outer piston tube 402, the outer piston tube 402 and the middle connecting pipe 401 remain closed. The inner piston 404 compresses and discharges the gas inside the outer piston tube 402 through the upper one-way exhaust port 403, and extracts the air inside the middle connecting pipe 401 and the inverted U-shaped guide pipe 4. The middle connecting pipe 401 and the inverted U-shaped guide pipe 4 are filled with liquid, realizing the connection of the liquid surfaces at both ends of the two inverted U-shaped guide pipes 4, and performing the diversion operation of mosquitoes inside the extended sub-box 102. There is no need to set up a valve body, avoiding the situation where mosquitoes remain due to valve opening and closing.

[0041] In Example 2, based on Example 1, the inverted U-shaped guide tube 4 is broken in the middle and divided into two parts. The two parts of the inverted U-shaped guide tube 4 are connected by a sliding pipe fitting. The distance between the two parts of the inverted U-shaped guide tube 4 is extended by the sliding and stretching of the pipe to adapt to the spacing distance of different containers and meet the needs of guiding flow in different containers.

[0042] The working principle of this embodiment is as follows: Water is poured into the space formed by the main incubation box 1, the extended auxiliary box 102, and the inner corrugated telescopic frame 101. Test strips containing mosquito eggs are placed in the water within this space. Then, the upper cover 2 slides horizontally in the top slide rail of the main incubation box 1. Simultaneously, the upper cover 2 pushes the extended cover 201 to the top of the extended auxiliary box 102. The positioning bracket 202 at the front end of the extended cover 201 and the upper locking block 109 slide, and the positioning bracket 202... The bottom of the first end moves upward along the top of the upper card block 109, and the positioning card holder 202 moves to the other side of the upper card block 109. The vertical surface of the upper card block 109 and the middle vertical surface of the positioning card holder 202 are attached to each other, completing the locking and fixing operation of the positioning card holder 202 and the upper card block 109. The position is fixed between the expansion cover plate 201 and the expansion sub-box 102. The upper cover plate 2 and the expansion cover plate 201 isolate the expansion sub-box 102 and the main incubation box 1 into a closed box. The main incubation box 1 can heat the water inside through the electric heating tube 107.

[0043] The main incubation chamber 1 and the extended auxiliary chamber 102 slide away from each other. Simultaneously, the main incubation chamber 1 and the extended auxiliary chamber 102 pull the central inner corrugated telescopic frame 101 to extend synchronously. The side connecting slide tube 103 and the side connecting slide column 104 slide away from each other. The upper connecting column 105 moves synchronously with the side connecting slide column 104. The tightening nut 106 moves along the thread of the upper connecting column 105 to tighten the side connecting slide tube 103, thus fixing the position between the side connecting slide tube 103 and the side connecting slide column 104. This also fixes the position between the main incubation chamber 1 and the extended auxiliary chamber 102. The combined space of the inner corrugated telescopic frame 101 becomes longer and larger, realizing the expansion and compression of the combined space of the main incubation box 1 and the extended auxiliary box 102. The internal space of the main incubation box 1 and the extended auxiliary box 102 is adjusted according to the number of mosquitoes hatched. When there are many mosquitoes hatched, the space is expanded to avoid the hatched mosquitoes affecting the unhatched ones. The upper cover plate 2 and the extended cover plate 201 move synchronously with the main incubation box 1 and the extended auxiliary box 102 to ensure a sealed cover. The upper cover plate 2 and the extended cover plate 201 move closer to shrink, reducing the space occupied by the main incubation box 1 and the extended auxiliary box 102 when they are not in use.

[0044] The feeding column 3 is pulled upwards, and the lower feeding platform 301 moves upwards to the lower through hole 205. The feed is placed on the lower feeding platform 301. The feeding column 3 and the lower feeding platform 301 move downwards simultaneously. The lower feeding platform 301 moves down into the water inside the main hatching box 1 and the extended auxiliary box 102 for feeding. As the feeding column 3 moves downwards, the lower through hole 205 is sealed to prevent adult insects from flying out through the lower through hole 205. The feeding column 3, the lower feeding platform 301, and the lower stirring tooth 302 rotate in a circular direction simultaneously. The feed on the lower feeding platform 301 is thrown out into the surrounding water to feed the newly hatched mosquitoes. The rotation of the lower stirring tooth 302 agitates the water inside the main hatching box 1 and the extended auxiliary box 102, further promoting the spread of the feed and promoting water flow to facilitate observation of the mosquitoes' condition.

[0045] The breathable mesh frame 203 is used for ventilation inside the main hatching box 1. When flying adults are already present inside the main hatching box 1, the breathable mesh frame 203 is slid to the outside of the upper cover plate 2. The through hole in the middle of the upper cover plate 2 exposes a channel connecting the main hatching box 1 and the extended secondary box 102, facilitating the extraction of pre-developed adults from the main hatching box 1 and the extended secondary box 102. The adults fly out through the channel or are connected to the subsequent adult rearing device via pipes. When it is necessary to divert the hatched mosquitoes inside the main hatching box 1, one end of the inverted U-shaped guide pipe 4 is below the water inside the extended secondary box 102, and the other end of the inverted U-shaped guide pipe 4 is in another container. Below the liquid surface, the inner piston 404 pulls the central connecting pipe 401 and the inverted U-shaped guide pipe 4 to draw in air. The inner piston 404 compresses and discharges the gas inside the outer piston pipe 402 through the upper one-way exhaust port 403, drawing out the air inside the central connecting pipe 401 and the inverted U-shaped guide pipe 4. The central connecting pipe 401 and the inverted U-shaped guide pipe 4 are filled with liquid, realizing the connection between the liquid surfaces at both ends of the two inverted U-shaped guide pipes 4. This facilitates the diversion operation of mosquitoes inside the extended auxiliary box 102. The inverted U-shaped guide pipe 4 moves upward and separates from the liquid surface inside the main hatching box 1 to disconnect the diversion operation. There is no need for a valve body, avoiding the situation where mosquitoes remain due to valve opening and closing, and reducing the loss of mosquito hatching and reproduction.
