Description

Technical Field

[0001] This utility model relates to the field of bioassay technology, specifically to an indoor bioassay device for pesticides. Background Technology

[0002] In the field of pesticide research and development and efficacy evaluation, indoor bioassay is a key step in verifying pesticide activity, toxicity and mechanism of action. With the deepening of the concepts of green agriculture and precision plant protection, the requirements for the accuracy, repeatability and timeliness of bioassay results are becoming increasingly stringent.

[0003] However, traditional bioassay devices often use simple sealed containers or open petri dishes. While these methods prevent insects from escaping by covering and sealing with adhesive, they also block air circulation, easily leading to insufficient oxygen and excessive carbon dioxide concentration in the experimental space. This can cause abnormal physiological states in insects or inhibit plant growth. Secondly, although some devices are equipped with ventilation holes, the holes are too large or lack protective measures, making it difficult to effectively prevent insects from escaping. Furthermore, the lack of a water management mechanism means that overwatering can easily lead to waterlogging and rotting, while drought can affect biological activity. In addition, leakage problems may cause cross-contamination between different experimental groups, interfering with the measurement results. Therefore, there is an urgent need for an indoor bioassay device for pesticides to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an indoor bioassay device for pesticides, in order to solve the problems mentioned in the background art, such as the low accuracy of current bioassays, the impact of insect escape on the accuracy of bioassays, and the fact that ventilation and water leakage affect the growth of insects and plants while ensuring that insects do not escape, thus affecting the accuracy and effectiveness of bioassays.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a device for indoor bioassay of pesticides, including a bioassay tank 1. A planting pot 2 is fixedly connected to the inner wall of the bioassay tank 1. A tripod 3 is fixedly connected to the bottom of the bioassay tank 1. An external water supply component 4 is provided on the surface of the planting pot 2. A sealing component 5 is provided on the top surface of the bioassay tank 1. A collection component 6 is provided on the bottom surface of the planting pot 2. The external water supply component 4 includes a water storage box 401, which is fixedly connected to the surface of the planting pot 2. Multiple water inlets 402 are provided on the inner wall of the planting pot 2. A fixing frame 403 is fixedly connected to the bottom surface of the tripod 3, and a fixing bracket 403 is fixedly connected to the side wall of the fixing frame 403. A water filling box 404 is provided, and a connecting hose 405 is fixedly connected to the inner wall of the water filling box 401. The surface of the connecting hose 405 is fixedly connected to the inner wall of the water storage box 401. Through the external water filling component 4, an appropriate amount of water is poured into the inner wall of the water filling box 404. The connecting hose 405, the water storage box 401 and multiple water inlets 402 work together to allow the water inside the water filling box 404 to flow into the planting pot 2. This makes it easy to add water to the inside of the planting pot 2 without touching it, thereby improving the convenience of watering and preventing insects inside the bioreactor 1 from escaping when adding water.

[0021] Furthermore, the sealing assembly 5 includes a sealing cover 501, which is disposed on the top surface of the bioreactor 1. A nylon mesh 502 is fixedly connected to the inner wall of the sealing cover 501. A limiting groove 505 is formed on the top surface of the bioreactor 1. The lower end of the sealing cover 501 abuts against the inner wall of the limiting groove 505. Both the bioreactor 1 and the sealing cover 501 are made of acrylic material. The sealing assembly 5 facilitates the sealing of the top surface of the bioreactor 1. At the same time, the nylon mesh 502 and the acrylic bioreactor 1 and sealing cover 501 facilitate better visibility, air permeability and light transmission of the organisms inside the bioreactor 1.

[0022] Furthermore, the collection component 6 includes a connecting frame 601, which is disposed on the bottom surface of the planting pot 2 and fixedly connected to the tripod 3. A sliding column 602 is slidably connected to the inner wall of the connecting frame 601, and a compression spring 603 is fixedly connected to the lower end of the sliding column 602. A collection box 604 is disposed on the top surface of the sliding column 602, and the upper end of the collection box 604 abuts against the lower end of the planting pot 2. The collection component 6 facilitates the collection of excess water overflowing from the planting pot 2. At the same time, the abutment between the upper end of the collection box 604 and the lower end of the planting pot 2 prevents insects from escaping from the overflow hole on the bottom surface of the planting pot 2.

[0023] Furthermore, a constraint block 406 is fitted onto the surface of the connecting hose 405. A sliding groove 407 is formed on the inner wall of the constraint block 406. A threaded hole 408 is formed on the inner wall of the sliding groove 407. A threaded post 409 is threadedly connected to the inner wall of the threaded hole 408. A pressing block 410 is slidably connected to the inner wall of the sliding groove 407. By using the constraint block 406, the threaded post 409, and the pressing block 410 in cooperation, it is easy to control the flow rate of added water and improve the accuracy of water addition.

[0024] Furthermore, a contact head 411 is fixedly connected to the side wall of the extrusion block 410. The contact head 411 is made of rubber. The surface of the threaded post 409 is rotatably connected to the extrusion block 410. The rubber contact head 411 facilitates flexible contact when the contact head 411 extrudes the connecting hose 405, thereby improving the service life of the connecting hose 405.

[0025] Furthermore, a fixing groove 503 is provided at the upper end of the sealing cover 501, and a counterweight 504 is fixedly connected to the inner wall of the fixing groove 503. The counterweight 504 makes it easier for the lower end of the sealing cover 501 to contact the inner wall of the limiting groove 505 more tightly.

[0026] Working principle: The sealing component 5 makes the bottom surface of the sealing cover 501 abut against the inner wall of the limiting groove 505, thus facilitating the sealing of the biological test tank 1. At the same time, the nylon mesh 502 provides good permeability while blocking insects, thereby avoiding the impact on the biological growth inside the biological test tank 1.

[0027] The external water-adding component 4 allows for easy addition of water to the inside of the biological testing tank 1 without opening the sealing cover 501, thus preventing insects inside the biological testing tank 1 from escaping when the sealing cover 501 is opened. At the same time, the constraint block 406, threaded column 409, and extrusion block 410 work together to facilitate control of the water flow rate and improve the accuracy of water addition.

[0028] The collection component 6 is designed so that the upper end of the collection box 604 abuts against the lower end of the planting pot 2 under the action of the compression spring 603, which facilitates the collection of water overflowing from the planting pot 2 and prevents insects inside the planting pot 2 from escaping through the overflow hole on the bottom of the planting pot 2.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
