Abstract
Description
Technical Field
[0001] This utility model relates to the field of human life necessities, especially to health care technology, and particularly to experimental technology for mite control, specifically a simple mite breeding device. Background Technology
[0002] Mites are a collective term for animals belonging to the order Acari of the class Arachnida, also known as fungal lice. More than 50,000 species of mites have been discovered worldwide, second only to insects. Many species are medically relevant. It has been found that mites are closely related to human health. Mites such as leather mites, chiggers, scabies mites, demodex mites, flour mites, and house dust mites can bite and suck blood, infest the skin, and cause conditions such as rosacea, demodicosis, allergies, urinary tract mite infestation, and scabies, seriously endangering human health. Currently, mite control mainly relies on chemical agents and environmental control measures, which can effectively reduce mite damage to a certain extent. However, scientific research on mites and the development of control products still face many challenges. To better conduct related research and understand the biological characteristics of mites and their adaptation mechanisms to the environment, a simple and effective mite rearing device is urgently needed. Existing mite rearing devices suffer from drawbacks such as complex operation and easy escape of mites, and cannot well meet current research needs. In addition, when using a sampling shovel to remove mites from the breeding tank and then placing them into a petri dish, the mites are prone to falling off or escaping from the sampling shovel. Utility Model Content
[0003] The purpose of this utility model is to provide a simple mite breeding device to solve the technical problems in the prior art, such as complicated operation, easy escape of mites from the breeding device, and easy fall or escape of mites from the sampling shovel during sampling.
[0004] This utility model provides a simple mite breeding device, including a box containing saturated saline solution. A corrosion-resistant mat is placed at the bottom center of the box, with the mat higher than the saline solution level. A breeding tank is located inside the box, with a lid on top. The breeding tank is situated on the mat. Ventilation holes with mesh screens are provided in the box. A top cover is attached to the box, with its rear side connected to the box via two hinges and its front side secured to the box via snap fasteners. A sampling box is located inside the box, adjacent to the breeding tank.
[0005] Furthermore, the pad is a ceramic tile, and the upper surface of the ceramic tile is a rough plane.
[0006] Furthermore, the upper surface of the pad is provided with a groove, and the bottom of the feeding tank is fitted into the groove.
[0007] Furthermore, adhesive boards with adhesive are affixed to the four side walls of the box at positions higher than the saturated salt water level.
[0008] Furthermore, a handle is provided on the upper side of the cover. After the cover is flipped open, the handle provides support, keeping the cover in an inverted and horizontal position. The left and right ends of the front side of the sampling box are hinged to the left and right ends of the box body by two parallel first connecting rods. The two ends of the first connecting rods are hinged to the sampling box and the box body, respectively. The left and right ends of the rear side of the sampling box are hinged to the cover by a second connecting rod. The two ends of the second connecting rods are hinged to the sampling box and the cover, respectively.
[0009] Furthermore, the feeding tank is located below the sampling box.
[0010] Furthermore, the sampling box contains a sponge and saturated saline solution, with the sponge submerged in the saline solution.
[0011] Compared with existing technologies, this invention offers positive and significant advantages. Its simple structure and convenient operation, coupled with the saturated saline solution within the enclosure to effectively prevent mite escape, and the freely opening and closing lid, allow for quick and easy observation, sampling, and feed replenishment during mite rearing and management, significantly reducing operation time and difficulty. In mite repellency or eradication experiments, placing the petri dish assembly into the sampling box, with its proximity to the rearing tank, greatly reduces mite falls or escapes during the shovel's movement from the rearing tank to the sampling box. Ventilation holes ensure air circulation within the enclosure, preventing oxygen deficiency from affecting mite growth, while the mesh screen prevents external environmental contamination of the enclosure's interior. The snap-fit design between the lid and the enclosure enhances the device's sealing and stability, maintaining excellent isolation. Attached Figure Description

[0016] The present invention will be further described below with reference to embodiments, but the present invention is not limited to these embodiments. Any similar variations using the present invention should be included within the protection scope of the present invention. The use of directions such as up, down, front, back, left, right, center, inside, and outside in the present invention is only for the convenience of clear description and is not intended to limit the technical solution of the present invention.
[0017] like Figures 1-4 As shown, this utility model provides a simple mite breeding device, including a box 1, which is filled with saturated saline solution. A corrosion-resistant pad 7 is laid in the middle of the bottom of the box 1, and the height of the pad 7 is higher than the surface of the saturated saline solution. A breeding tank 8 is set inside the box 1, and a tank cover 12 is set on the breeding tank 8. The breeding tank 8 is located on the pad 7. A ventilation hole 4 is set on the box 1, and a mesh is set in the ventilation hole 4. A top cover 2 is set on the box 1. The rear side of the top cover 2 is connected to the box 1 by two hinges 13, and the front side of the top cover 2 is fixed to the box 1 by a buckle 5. A sampling box 11 is set inside the box 1, and the sampling box 11 is set adjacent to the breeding tank 8.
[0018] Under light-protected conditions, mites can crawl along the inner wall of the rearing tank 8 to the lower surface of the tank cover 12. When taking samples, the tank cover 12 can be opened and a sampling shovel can be used to scoop out the mites needed for the experiment from the lower surface of the tank cover 12.
[0019] Mite repellency test method: Example
[0020] The repellency effect of treated textiles against dust mites was tested according to the repellency method in GB / T 24253-2009 "Evaluation of anti-mite performance of textiles".
[0021] like Figure 4 As shown, a sponge 19, 10mm thick and approximately 200mm on each side, is placed inside a covered container. An appropriate amount of saturated salt water is then poured into the container, the salt water level just submerging the sponge 19. Figure 3As shown, take seven petri dishes and place one petri dish in the center of a mounting plate 16 as the central petri dish. Arrange the remaining six petri dishes evenly around the central petri dish in a petal-like pattern, securing the edges of adjacent petri dishes with transparent tape of equal width (acting as a bridge). All seven petri dishes are fixed to the mounting plate 16. Place the sample 17 and control sample 18 alternately in the six outer petri dishes. Arrange the sample and control samples evenly, flatly, and tightly at the bottom of the petri dishes, and place 0.05g of mite feed in the center of each sample and control sample. Open the top cover 2 of the box 1, place the petri dish assembly 9 (consisting of seven petri dishes and the mounting plate 16) in the sampling box 11, and use a flat-tipped sampling spatula to scoop 2000±200 surviving mites from the tank cover 12 on the rearing tank 8 and place them in the central petri dish. Then, place the petri dish assembly 9 on the sponge 19 in the container, cover the container with the lid, and place the container in an environment with a temperature of (25±2)℃ and a relative humidity of (75±5)%.
[0022] After 24 hours of incubation, the number of surviving mites in the sample culture dish and control culture dish was observed using a dissecting microscope or stereomicroscope and counted using appropriate methods.
[0023] The avoidance rate is calculated using the following formula and expressed as a percentage (%):
[0024]
[0025] Where: Q—approach-avoidance ratio; B —The average number of surviving mites in the three control culture dishes; T—The average number of surviving mites in the three sample culture dishes.
[0026] This invention features a simple structure and convenient operation. The saturated saline solution inside the box 1 effectively prevents mites from escaping. The top cover 2 can be opened and closed freely, allowing for quick and easy observation, sampling, and feed replenishment during mite rearing and management, significantly reducing operation time and difficulty. During mite repellency or eradication experiments, the culture dish assembly 9 is placed inside the sampling box 11. Because the sampling box 11 is close to the rearing tank 8, the process of shoveling mites from the rearing tank 8 and moving them to the sampling box 11 greatly reduces the risk of mites falling or escaping. Ventilation holes 4 ensure air circulation inside the box 1, preventing oxygen deficiency from affecting mite growth. The mesh screen prevents external environmental contamination of the inside of the box 1. The snap-fit design between the top cover 2 and the box 1 enhances the sealing and stability of the device, maintaining good isolation.
[0027] Furthermore, the pad 7 is a ceramic tile, and the upper surface of the ceramic tile is a rough plane.
[0028] Furthermore, the upper surface of the pad 7 is provided with a groove, and the bottom of the breeding tank 8 is fitted into the groove to prevent the breeding tank 8 from moving, effectively preventing feed spillage or mite escape caused by movement, and ensuring the safe breeding of mites.
[0029] Furthermore, adhesive boards 10 are affixed to the four side walls of the box 1 at positions above the saturated saline solution. The adhesive boards 10 are coated with adhesive, allowing mites to be trapped and prevented from escaping. The adhesive boards can be replaced periodically based on the mite attachment levels. The box 1 is made of corrosion-resistant material.
[0030] Furthermore, a handle 3 is provided on the upper side of the upper cover 2. After the upper cover 2 is flipped open, the handle 3 provides support, so that the upper cover 2 is in an inverted horizontal state. The left and right ends of the front side of the sampling box 11 are respectively hinged to the left and right ends of the box body 1 by two parallel first connecting rods 14. The two ends of the first connecting rods 14 are respectively hinged to the sampling box 11 and the box body 1. The left and right ends of the rear side of the sampling box 11 are respectively hinged to the upper cover 2 by a second connecting rod 6. The two ends of the second connecting rod 6 are respectively hinged to the sampling box 11 and the upper cover 2.
[0031] The handle 3 of the top cover 2 not only maintains the stability of the top cover, but also serves as a handle for easy use during movement and maintenance. The sampling box 11 forms a four-bar linkage with the box body 1 through the first connecting rod 14. When the top cover is opened for sampling, the top cover 2 drives the sampling box 11 to rise through the second connecting rod 6. At the same time, the sampling box 11 can always remain horizontal, thereby preventing the petri dish assembly 9 from sliding due to tilting during the sampling process.
[0032] Furthermore, the breeding tank 8 is located below the sampling box 11.
[0033] Furthermore, the sampling box 11 is equipped with a sponge and saturated saline solution. The saturated saline solution submerges the sponge, which can further reduce the escape of mites during the mites collection process.
[0034] Specifically, the mesh, buckle 5, saturated salt water, adhesive board 10, and other components not described in detail in this utility model all adopt well-known solutions in the prior art, which are already understood by those skilled in the art and will not be elaborated here.
