[0002] Fruit flies are important pests of horticultural fruits in the Asia-Pacific region. They have strong reproductive capacity and a wide range of hosts. Their damage can be seen all year round and causes significant economic losses. They are also important pests in the international agricultural product trade. Fruit fly attractant is an attractant used to control fruit flies, usually used in conjunction with traps.

[0003] When the existing trap is used, an attractant liquid is usually injected into the interior of the trap, and the fruit flies are attracted by emitting a special smell, so that they enter the interior of the trap and are killed. However, the existing trap is not convenient for appropriately and automatically replenishing the attractant. There are two common ways to add the attractant: one is to place a large amount of attractant into the trap, but this evaporates quickly and has poor durability; the other is to place a small amount of attractant into the trap frequently, but this is time-consuming and labor-intensive, and increases labor costs. Therefore, we need to propose a fruit fly trap. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-4 The utility model provides a technical solution: a fruit fly trap, comprising a trap body 1, a top cover 2 is installed on the top of the trap body 1, and a liquid storage component for storing attractants is plugged into the top of the top cover 2; the liquid storage component comprises a liquid storage tank 4, the liquid storage tank 4 is plugged into the inside of the top cover 2, the bottom of the liquid storage tank 4 extends to the inside of the trap body 1 and is located above the float 3, and a sealing cover 5 is detachably installed on the top of the liquid storage tank 4. The inside of the trap body 1 can store the attractant, and the top cover 2 is used to seal the top of the trap body 1. The sealing cover 5 can be opened to inject the attractant liquid into the liquid storage tank 4. The sealing of the sealing cover 5 can reduce the volatilization of the attractant liquid in the liquid storage tank 4.

[0026] Among them, a first limiting ring 6 is installed on the top of the inner cavity of the top cover 2, and a second limiting ring 7 is sleeved on the outside of the liquid storage tank 4, and the bottom of the second limiting ring 7 fits with the bottom of the first limiting ring 6. By setting the first limiting ring 6 and the second limiting ring 7, the top cover 2 can be connected to the trap body 1. The top of the trap body 1 and the bottom of the top cover 2 are sleeved with connecting rings 8, and the connecting rings 8 are connected by bolts. Connecting blocks 9 are installed around the outside of the top cover 2, and the connecting blocks 9 are provided to facilitate the installation and connection of the trap.

[0027] Furthermore, the bottom of the liquid storage component extends to the inside of the trap body 1, and a control component that can control the liquid storage component to automatically discharge an appropriate amount of liquid is installed at the bottom of the liquid storage component; a float 3 is arranged at the bottom of the inner cavity of the trap body 1, and the top of the float 3 is in contact with one side of the bottom of the control component; the control component includes a bracket 10, the bracket 10 is installed at the bottom of one side of the liquid storage tank 4, and a liquid injection hole 11 is opened at the bottom of the liquid storage tank 4 and located on the side close to the bracket 10, and a rotating shaft is rotatably installed at both ends of the outer side of the bracket 10, and a support block 12 is installed at one end of the rotating shaft away from the bracket 10, and a valve plate 13 is installed on one side of the support block 12, and a sealing block 14 is installed on the top of the valve plate 13, and a sealing gasket 15 is sleeved on the top of the sealing block 14, and the top of the sealing gasket 15 is in contact with the bottom of the liquid injection hole 11. By setting the liquid injection hole 11, the attractant stored in the liquid storage tank 4 can enter the bottom of the inner cavity of the trap body 1 through the liquid injection hole 11.

[0028] Specifically, a large amount of attractant is injected into the liquid storage tank 4, and the attractant liquid flows into the bottom of the inner cavity of the trap body 1 through the liquid injection hole 11. At the same time, the liquid generates buoyancy, and the float 3 floats up and pushes the valve plate 13. The valve plate 13 drives the sealing block 14 and the sealing gasket 15 to seal the liquid injection hole 11. After the liquid level rises to a certain height, the liquid injection through the liquid injection hole 11 is stopped, and the liquid storage tank 4 can be sealed to reduce volatilization.

[0029] It is worth noting that the attractant inside the trap body 1 can gradually evaporate, producing an odor that attracts fruit flies, and at the same time its own volume continues to decrease, so that the liquid level inside the trap body 1 will gradually decrease, and the height of the float 3 will also decrease accordingly, so that the valve plate 13 and the sealing block 14 will drop again under the influence of gravity. At this time, the blockage of the injection hole 11 is released, and the attractant in the liquid storage tank 4 will be replenished into the interior of the trap body 1 again, so that the purpose of automatic quantitative replenishment of the attractant can be achieved, and the durability of the trap to attract insects can be improved, while bringing convenience to the control of fruit flies.

[0030] Furthermore, an entry assembly for emitting odor and providing a trapping channel for fruit flies is embedded on both sides of the trap body 1 and above the control assembly. The entry assembly includes a plate body 20 embedded on both sides of the trap body 1, and a short tube 21 is embedded inside the plate body 20. The inside of the trap body 1 is connected to the outside of the trap body 1 through the short tube 21. The odor generated by the attractant is emitted to the outside of the trap body 1 through the short tube 21, attracting the surrounding fruit flies. The fruit flies enter the inside of the trap body 1 through the short tube 21 under the attraction of the odor, and are then attracted by the attractant and submerged in the attractant inside the trap body 1, thereby achieving the purpose of trapping.

[0031] The size and shape of the inner passage of the short tube 21 can be changed according to the fruit fly.

[0032] In addition, a screw rod 16 is threadedly connected to the outside of the trap body 1 and located at a position corresponding to the bracket 10. One end of the screw rod 16 extends to the inside of the trap body 1 and is rotatably installed with a positioning block 17. One side of the positioning block 17 is in contact with one side of the support block 12. By rotating the screw rod 16, the positioning block 17 is driven to move while the screw rod 16 rotates. After one side of the positioning block 17 is separated from one side of the support block 12, the valve plate 13 can rotate accordingly.

[0033] A limiting rod 18 is installed at the bottom of the inner cavity of the trap body 1. The limiting rod 18 is provided in three groups and is equidistantly slidably fitted on the outer side of the float 3. The limiting rod 18 is provided to limit the moving trajectory of the float 3. A debris discharge port is provided at the bottom of the inner cavity of the trap body 1. A blocking block 19 is threadedly connected to the bottom of the debris discharge port. When a large number of fruit flies accumulate in the trap body 1 and need to be cleaned, the screw rod 16 is rotated to drive the positioning block 17 to squeeze and limit the support block 12 to prevent the support block 12 from rotating. In this way, even if the liquid level inside the trap body 1 drops, the sealing gasket 15 will not drop, and the injection hole 11 can be kept blocked. At this time, the blocking block 19 is disassembled by rotating the blocking block 19, and the fruit flies and waste liquid therein can be discharged through the debris discharge port, so that the unused attractant stored in the liquid storage tank 4 will not leak when cleaning the fruit flies.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
