Description

Technical Field

[0001] This invention belongs to the field of biological sampling technology, specifically a biological sampler for biological specimens. Background Technology

[0002] Biological sampling refers to the operation of obtaining representative samples from an organism or its living environment for biological research, analysis and detection purposes. When sampling biological samples from an organism, it is necessary to use a biological sampler.

[0003] There are many types of biological samplers, and different types of samplers are suitable for different organisms and sample types.

[0004] When sampling biological specimens from flying insects, these insects are small, fly fast, and are difficult to capture. When using clamps, the insects are captured and cannot die quickly, rendering the sampling device unusable until the insects die. Furthermore, removing the insects can easily damage the integrity of the sample. Some flying insects contain toxins, making it difficult to remove them after sampling. Therefore, to address these issues, a biological sampler for biological specimens is proposed. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and address the problems of existing equipment, this utility model proposes a biological sampler for biological specimens.

[0006] The technical solution adopted by this utility model to solve its technical problem is a biological sampler for biological specimens, including an air extraction cylinder. An air extraction component is installed inside the air extraction cylinder to extract the air inside the air extraction cylinder. An insertion interface is provided at the bottom of the inner wall of the air extraction cylinder, and a collection component is provided inside the insertion interface for collecting flying insect samples.

[0007] The collecting assembly includes a collecting cylinder that is inserted into the connector. A baffle plate is snapped into the inner wall of the collecting cylinder. A through hole is provided at the top of the baffle plate. A collecting sieve plate is provided at the bottom of the baffle plate. A conical hopper is fixedly installed at the bottom of the collecting cylinder. A flaring assembly is provided at the bottom of the conical hopper to enlarge the inlet end of the bottom of the conical hopper.

[0008] Preferably, the collecting screen plate is installed on the inner wall of the collecting cylinder, and a lifting column is fixedly installed on the top of the barrier plate.

[0009] Preferably, the flared assembly includes a threaded interface fixedly installed at the bottom of the conical hopper one, a conical hopper two being threadedly connected to the inside of the threaded interface, a conical hopper three being fixedly installed at the top of the conical hopper two, and the conical hopper three being disposed inside the conical hopper one.

[0010] Furthermore, the cone-shaped buckets II and III can be fitted with different diameters to accommodate the capture of different flying insects.

[0011] Preferably, the air extraction assembly includes a hole formed at the top of the air extraction cylinder, a pulling column is slidably installed inside the hole, the bottom of the pulling column extends into the air extraction cylinder and an annular plate is installed thereon, and a sealing rubber gasket is installed at the top of the annular plate.

[0012] Preferably, an annular sleeve is fixedly installed on the inner wall of the air extraction cylinder, and a filter screen is installed inside the annular sleeve.

[0013] Furthermore, the annular sleeve can block and limit the movement of the annular plate, and the filter screen can filter dust and impurities in the air, preventing dust from entering the interior of the suction cylinder.

[0014] Preferably, a light is installed at the bottom of the inner wall of the vacuum pump, and a battery is fitted onto the outer surface of the vacuum pump, with the battery electrically connected to the light.

[0015] The beneficial effects of this utility model are:

[0016] 1. In this utility model, when flying insects gather at the second cone-shaped bucket, the pulling column is quickly pulled upwards, causing the annular plate and sealing rubber pad to move upwards along the inner wall of the suction cylinder, drawing out the air inside the suction cylinder and the collection cylinder, reducing the air pressure inside the collection cylinder and creating a negative pressure. This draws the flying insects at the second cone-shaped bucket into the inside of the collection cylinder. The flying insects can be blocked by the collection sieve plate, which buffers them and ensures their integrity. The third cone-shaped bucket retracts into the collection cylinder to prevent the flying insects from flying out of the collection cylinder. The collection cylinder can then be removed to preserve the sampled and captured flying insects.

[0017] 2. In this utility model, when a flying insect dies and becomes a biological specimen, pulling the lifting column can pull out the baffle plate and remove the collection sieve plate. The insects that have become biological samples accumulate on the collection sieve 204, and the flying insect specimens can be directly removed, achieving the effect of capturing and sampling flying insects and preserving the integrity of the flying insect samples. Other collection tubes can also be inserted into the vacuum tube again to continue to sample and capture flying insects. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-5 As shown, a biological sampler for biological specimens includes an air extraction cylinder 1, an air extraction assembly 11 installed inside the air extraction cylinder 1 for extracting air from inside the air extraction cylinder 1, and an insertion interface 12 opened at the bottom of the inner wall of the air extraction cylinder 1. A collection assembly 2 is provided inside the insertion interface 12 for collecting flying insect samples.

[0028] Furthermore, by installing an air extraction component 11 inside the air extraction cylinder 1, the air inside the air extraction cylinder 1 can be extracted. Then, by pulling the air extraction component 11, the air inside the air extraction cylinder 1 and the collection component 2 installed at the bottom of the air extraction cylinder 1 can be extracted together, which increases the internal volume of the collection component 2, reduces the air pressure, and forms a negative pressure, which sucks the flying insects at the air inlet of the air extraction component 11 into the interior of the air extraction component 11 for capture and sampling.

[0029] First, considering the question of how to capture insects inside collection component 2, we present... Figures 1-3 The specific structure of the collecting component 2 and the flaring component 3 is disclosed. The collecting component 2 includes a collecting cylinder 201 that is inserted into the insertion interface 12. A baffle plate 202 is snapped into the inner wall of the collecting cylinder 201. A through hole 203 is provided at the top of the baffle plate 202. A collecting sieve plate 204 is provided at the bottom of the baffle plate 202. A conical bucket 205 is fixedly installed at the bottom of the collecting cylinder 201. A flaring component 3 is provided at the bottom of the conical bucket 205 to enlarge the inlet end of the bottom of the conical bucket 205.

[0030] A collecting screen plate 204 is installed on the inner wall of the collecting cylinder 201, and a lifting column 4 is fixedly installed on the top of the baffle plate 202. The flared assembly 3 includes a threaded interface 301 fixedly installed at the bottom of the conical hopper 1 205, a conical hopper 2 302 is threadedly connected to the inside of the threaded interface 301, a conical hopper 303 is fixedly installed on the top of the conical hopper 2 302, and the conical hopper 303 is located inside the conical hopper 1 205.

[0031] Furthermore, the collecting cylinder 201 is inserted into the insertion interface 12 at the bottom of the suction cylinder 1, making the collecting cylinder 201 and the suction cylinder 1 an integral unit. The baffle plate 202 and the collecting sieve plate 204 are both installed on the inner wall of the collecting cylinder 201. Pulling the lifting column 4 allows the baffle plate 202 to be pulled out, facilitating the removal of the collecting sieve plate 204 from the inside of the collecting cylinder 201. The baffle plate 202 has multiple through holes 203 at its top, and the collecting sieve plate 204 has multiple sieve holes at its top, ensuring that the suction assembly 11 can extract air from the inside of the collecting cylinder 201. The conical bucket 205 is fixedly installed at the bottom of the collecting cylinder 201, reducing the size of the air inlet at the bottom of the collecting cylinder 201 and preventing air from entering the bottom of the collecting cylinder 201. If the opening is too large, it will affect the air extraction efficiency. Furthermore, the conical hopper 2 302 is threaded into the inside of the threaded interface 301, and the top of the conical hopper 2 302 is inserted into the inside of the conical hopper 1 205 and the conical hopper 3 303 is installed. This allows the conical hopper 2 302 to increase the opening of the conical hopper 1 205, making it easier for flying insects to enter the inside of the collection cylinder 201. The conical hopper 3 303 reduces the size of the conical hopper 2 302, which can prevent flying insects from flying out of the inside of the collection cylinder 201. Then, the air extraction component 11 can work to extract the air inside the collection cylinder 201, sucking the flying insects from the conical hopper 2 302 into the inside of the collection cylinder 201, blocking them at the bottom of the collection sieve plate 204, thus achieving the effect of capturing and sampling flying insects.

[0032] Secondly, considering the issue of how to extract the air from the vacuum pump 1 and the collection cylinder 201, the following is presented: Figure 4 and Figure 5 The specific structure of the air extraction assembly 11 is disclosed. The air extraction assembly 11 includes a hole opened at the top of the air extraction cylinder 1. A pulling column 101 is slidably installed inside the hole. The bottom of the pulling column 101 extends into the air extraction cylinder 1 and an annular plate 102 is installed thereon. A sealing rubber gasket 103 is installed at the top of the annular plate 102.

[0033] An annular sleeve 5 is fixedly installed on the inner wall of the air extraction cylinder 1, and a filter screen 51 is installed inside the annular sleeve 5.

[0034] Furthermore, a hole is made at the top of the suction cylinder 1, allowing the pulling column 101 to slide inside the hole. The bottom of the pulling column 101 is then inserted into the suction cylinder 1 to install the annular plate 102. A sealing rubber gasket 103 is installed on the top of the annular plate 102. Pulling the pulling column 101 upwards causes the annular plate 102 and the sealing rubber gasket 103 to slide inside the suction cylinder 1, thus evacuating air from the suction cylinder 1 and the collection cylinder 201. The sealing rubber gasket 103 fits tightly against the inner wall of the suction cylinder 1. An annular sleeve 5 and a filter screen 51 are installed on the inner wall of the suction cylinder 1. The annular sleeve 5 blocks the annular plate 102, limiting its downward movement. The filter screen 51 blocks dust and impurities from the air drawn from the collection cylinder 201, preventing dust and impurities from entering the suction cylinder 1.

[0035] Finally, considering how flying insects approach the cone-shaped bucket 302 and are sucked into the collection tube 201, the following is presented: Figure 3 and Figure 4 A light 6 is installed at the bottom of the inner wall of the air pump 1, and a battery 61 is sleeved on the outer surface of the air pump 1. The battery 61 is electrically connected to the light 6.

[0036] Furthermore, three lights 6 are installed on the inner wall of the suction cylinder 1, and a battery 61 is fitted onto the outer surface of the suction cylinder 1, allowing the battery 61 to be connected to the lights 6 via wires. A switch is installed on the outer surface of the suction cylinder 1, which can be used to power the lights. At night, turning on the switch allows the battery 61 to power the lights 6, enabling the light source to pass through the barrier plate 202 and the collection sieve plate 204 to illuminate the conical bucket 302, attracting insects and drawing air out of the collection cylinder 201 and suction cylinder 1 to capture and sample flying insects. During the day, a coating to attract flying insects can also be applied to the inner wall of the conical bucket 302 to attract flying insects to the conical bucket 302.

[0037] In summary, the working principle of this utility model is as follows:

[0038] When capturing samples of flying insects, the collection tube 201 is inserted into the air extraction tube 1. Conical hoppers 303 of different diameters are installed into the threaded interface 301 according to the different sizes of flying insects. During daytime sampling of flying insects, an insect-attracting agent is applied to the inner wall of the conical hopper 302. When the flying insects gather at the conical hopper 302, the pulling column 101 is pulled upwards quickly, causing the annular plate 102 and the sealing rubber gasket 103 to move upwards along the inner wall of the air extraction tube 1, drawing air out of the air extraction tube 1 and the collection tube 201. This reduces the air pressure inside the collection tube 201, forming a... A negative pressure is created, drawing flying insects from the conical bucket 302 into the collection cylinder 201. The flying insects are blocked by the collection sieve plate 204, which buffers them and ensures their integrity. The conical bucket 303 retracts into the collection cylinder 201 to prevent the flying insects from flying out. The collection cylinder 201 can be removed to preserve the sampled flying insects until they die and become biological specimens. Other collection cylinders 201 can be inserted into the vacuum pump 1 to continue sampling and capturing flying insects, thus achieving the effect of sampling and capturing flying insects as biological specimens.

[0039] When capturing flying insects at night, the operation is the same as described above. Simply turn on the switch of the light lamp 6 so that the light source of the light lamp 6 shines on the cone-shaped bucket 302, which can attract flying insects. Pulling the air extraction component 11 will also capture the flying insects into the collection tube 201. After the flying insects become biological specimens, pulling the lifting column 4 can pull out the baffle plate 202 and take out the collection sieve plate 204. The insects that have become biological samples accumulate on the collection sieve 204, and the flying insect specimens can be directly taken out, which achieves the effect of conveniently capturing and sampling flying insects and preserving the integrity of the flying insect samples.
