Description

Technical Field

[0001] This utility model relates to the field of toxicity testing devices, and more particularly to a device for testing the toxicity of thrips in daylily flowers. Background Technology

[0002] Toxicity testing is a quantitative expression of toxicity, i.e., the degree of toxicity. A toxicity testing device is a device used to assess the toxic effects of a compound on organisms. Its purpose is to help determine the toxicity and effectiveness of pesticides or other control agents by measuring indicators such as the survival rate and behavioral changes of the organisms.

[0003] However, existing devices suffer from biological escape during testing, which severely affects the accuracy of test results and makes it impossible to fully reflect the true effects of toxicity. Utility Model Content

[0004] The present invention aims to provide a device for determining the toxicity of thrips in daylily flowers, in order to solve the problem of biological escape during the testing process of existing devices.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] The basic technical solution provided by this utility model is: a device for determining the toxicity of thrips in daylily flowers, including a base, a cover movably connected to the base, the cover having an air vent, an annular groove and a dispensing hole, a thin film provided at the air vent, a fixing member for fixing the thin film detachably connected to the annular groove, a sealing piston movably connected to the dispensing hole, and an escape prevention component rotatably connected inside the dispensing hole.

[0007] The escape prevention component includes a support rod, which is rotatably connected to the delivery hole, and several arc-shaped fan blades are evenly distributed on the support rod.

[0008] The principle and beneficial effects of the basic technical solution: The membrane effectively seals the vent, preventing insects from escaping, while simultaneously facilitating gas exchange between the inside and outside of the device. The design of the annular groove and fixing components ensures the membrane's periphery is properly compressed and fixed within the groove. This not only guarantees a stable connection of the membrane to the cover but also allows for membrane removability, facilitating the replacement of different types of membranes to perform toxicity tests on different species. During the process of placing insects into the base through the release hole, the insects come into contact with the curved fan blades, which rotate around the support rod. This rotational motion effectively delivers the insects into the base. As the operator retrieves and places the insects in, the escape-prevention component keeps the release hole sealed, preventing insects from easily escaping and effectively improving the accuracy of the experiment.

[0009] Preferably, the annular groove is provided with a plurality of limiting holes, the fixing member is fixedly connected with a plurality of elastic plates, and the elastic plates are provided with limiting blocks that match the limiting holes.

[0010] With the above configuration, the limiting hole in the annular groove interacts with the limiting block on the elastic sheet to firmly fix the cover to the film, preventing the film from shifting or loosening and avoiding the escape of insects.

[0011] Preferably, the film has 45, 60, 75, or 90 pores.

[0012] By using the above settings, different numbers of pores can be selected for the membrane according to the insect species or the different sizes of the insects at different stages, which can effectively prevent insects from escaping through the membrane and also enable gas exchange between the inside and outside of the device.

[0013] Preferably, the base and the cover are fixed and locked together by threads.

[0014] The above design effectively ensures a secure connection between the base and the cover, preventing loosening or detachment during use. This threaded connection not only provides good mechanical strength but also facilitates quick assembly and disassembly, making it convenient for users to maintain and clean.

[0015] Preferably, both the base and the cover are made of transparent material.

[0016] The above setup provides excellent visibility, allowing operators to clearly observe the state of the insects inside, monitor changes during the experiment in real time, and promptly identify potential problems, thereby improving the safety and efficiency of the experiment.

[0017] Preferably, a recording label is affixed to the outer wall of the base.

[0018] The above settings make it easier for operators to record important information such as experimental data and dates during use. This not only helps to organize and manage experimental records and improve work efficiency, but also reduces the risk of errors caused by forgotten or confused information.

[0019] Preferably, the arc-shaped fan blades are made of high-quality polyethylene or polypropylene material to ensure their smoothness.

[0020] The above design ensures the smoothness of the curved fan blades, allowing insects to slide smoothly into the base while reducing their ability to adhere to the blades, thus further minimizing the possibility of escape. Attached Figure Description

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0028] like Figures 1 to 5 The device shown is for determining the toxicity of thrips in daylily flowers. It includes a base 1 with a recording label 10 affixed to its outer wall. A cover 2 is threadedly connected to the base 1. Both the cover 2 and the base 1 are made of transparent material. The cover 2 has a vent 3, an annular groove 4, and a dispensing hole 5. A film 6 is provided at the vent 3. The film 6 has 45, 60, 75, or 90 holes. A fixing element 7 for fixing the film 6 is detachably connected to the annular groove 4. Two limiting holes 41 are provided in the annular groove 4. Two elastic plates 71 are fixedly connected to the fixing element 7. Limiting blocks 72 that match the limiting holes 41 are provided on the elastic plates 71. A sealed piston 8 is movably connected to the dispensing hole 5. A support rod 91 is rotatably connected inside the dispensing hole 5. Several arc-shaped fan blades 92 are evenly distributed on the support rod 91. The arc-shaped fan blades 92 are made of high-quality polyethylene or polypropylene material.

[0029] The specific implementation process is as follows:

[0030] First, select a film 6 of appropriate size according to the growth stage and size of the object to be realized. Then, use the film 6 to cover the vent 3 and use the fastener 7 to squeeze the periphery of the film 6 into the annular groove 4. Through the cooperation between the limiting hole in the annular groove 4 and the limiting block 72 on the fastener 7, the film 6 is fixed on the cover 2.

[0031] Secondly, the operator selects appropriate insect food according to the type of insect, sprays or soaks the food with a predetermined amount of medicine, puts the food into the base 1, and fixes and locks the base 1 and the cover 2 with threads.

[0032] Then, the operator holds the insect and puts it into the device through the release hole 5, and puts the sealing piston 8 into the release hole 5 to complete the sealing of the release hole 5. During the release process, when the operating tool or the insect comes into contact with the arc-shaped fan blade 92, the arc-shaped fan blade 92 rotates and brings the insect into the device. During the operation, the escape prevention component keeps the release hole 5 in a sealed state, so that the insect will not easily escape.

[0033] Finally, the operator records the relevant experimental data on the recording label 10 based on the measurement results, thus completing the toxicity test experiment on the insect.

[0034] The above descriptions are merely embodiments of this utility model. Commonly known technical solutions or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application should be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
