[0002] Entomology is the science that studies insects. People who study insects are called entomologists. Entomologists all over the world observe, collect, raise, and experiment with insects. Insect collection is the foundation of insect research and is also of great significance in pest control. By collecting insects, we can understand the occurrence patterns, population dynamics, and distribution range of pests, so as to take targeted control measures.

[0003] Patent CN 204707820 U discloses an electric insect suction device, including an electric suction device and an insect collection device. The electric suction device includes a housing with a gun-shaped structure and a handle at the rear. A motor is installed inside, and the motor's output shaft is fixed to a fan blade. The handle contains a battery box, and an external power interface is located on the side of the handle. The motor is connected to the battery box and the external power interface via a switch. A battery cover is located at the bottom of the handle, and the cover is secured to the handle by a rotating latch. Air outlets are located on both sides of the housing near the fan blade. The insect collection device includes an insect inlet tube, an insect storage tube, a front piston, and a rear piston. The front and rear ends of the insect storage tube are connected to the front and rear pistons, respectively. The insect inlet tube is connected to the insect storage tube via the front piston, and the air inlet of the housing is connected to the insect storage tube via the rear piston.

[0004] However, the device still has the following problems:

[0005] 1. Because many types of insects have barbs on their legs, when the suction device picks up the insects, the barbs on their legs can easily get caught on the filter screen when the insects reach the screen, affecting the subsequent picking up of insects. In addition, some grit or impurities can easily accumulate on the filter screen and cause blockages.

[0006] 2. After the insects have been sucked up, if the opening is not sealed in time when removing the insect collection device from the suction device, the insects may escape. Utility Model Content

[0007] To address the problems existing in the prior art, a handheld insect collector is provided to solve the problems mentioned in the above-mentioned technical background.

[0008] The technical solution adopted by this utility model to solve its technical problem is:

[0009] This utility model proposes a handheld insect collector, including a shell, a straw at the front end of the shell, an air pump at the rear end of the shell, the air pump being connected to the rear end of the straw, a collection port at the lower end of the straw, a collection bottle being detachably connected to the collection port, a filter screen being disposed between the collection port and the air pump, the lower end of the filter screen being aligned with the rear end of the collection port, and a cleaning component for cleaning the filter screen being disposed at the upper end of the filter screen.

[0010] Preferably, the cleaning component is a brush, and the upper end of the suction tube protrudes upward to form a slide cylinder, and the brush is slidably disposed inside the slide cylinder.

[0011] Preferably, an electromagnet is fixed inside the slide cylinder, and the electromagnet can drive the brush to slide when energized.

[0012] Preferably, the brush is connected to the slide cylinder via a compression spring, and the magnetic force of the electromagnet is greater than the elastic force of the compression spring.

[0013] Preferably, a handle is fixed to the rear end of the housing, and the handle is provided with a button for controlling the power supply to and from the electromagnet and the air pump.

[0014] Preferably, a switch is fixed inside the slide cylinder, the air pump is electrically connected to the switch, and the switch cooperates with the brush.

[0015] Preferably, the filter screen is inclined inside the straw, and the sliding direction of the brush is consistent with the inclination direction of the filter screen.

[0016] Preferably, the collection bottle has two flaps rotatably connected inside, the flaps are connected to the collection bottle by a coil spring, and a top rod that can drive the flaps to rotate is slidably on the collection bottle.

[0017] Preferably, the bottom of the collection bottle is threaded with an end cap.

[0018] Preferably, the front end of the straw is detachably connected to a suction head.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. This utility model is equipped with a cleaning component. After the insects are sucked up, the cleaning component is used to clean the filter screen, which can keep the mesh of the filter screen unobstructed and maintain the suction power of the air pump. At the same time, the cleaning component can also push the insects hooked on the filter screen into the collection bottle, which helps to reduce the occurrence of insect escape, improve the collection efficiency of insects, and reduce the impact on subsequent insect sucking.

[0021] 2. This utility model is equipped with an electromagnet. After pressing the button, the electromagnet is energized and drives the brush to slide. Only after the brush is in position is the switch pressed to energize the air pump. After the brush avoids the filter screen, the air pump is energized, which effectively prevents the brush from clogging the filter screen and affecting the suction power of the air pump. At the same time, after the electromagnet is de-energized, the brush is driven to slide downward under the action of the compression spring, which can block the collection port and help reduce the occurrence of insect escape.

[0022] 3. The collection bottle of this utility model is equipped with a flap and a top rod. After the collection bottle is screwed onto the straw, the top rod can drive the flap to open, making it convenient to collect insects. After the collection bottle is screwed off, the flap closes under the action of the coil spring, which is convenient for changing and carrying the collection bottle and prevents insects from escaping.

[0031] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0032] refer to Figures 1-5This embodiment proposes a handheld insect collector, including a housing 1. A straw 2 is fixedly installed at the front end of the housing 1, and an air pump 3 is detachably installed at the rear end of the housing 1. The air pump 3 is connected to the rear end of the straw 2. A collection port is opened at the lower end of the straw 2. A collection bottle 5 is detachably connected to the collection port. A filter screen 4 is installed between the collection port and the air pump 3. The lower end of the filter screen 4 is aligned with the rear end of the collection port. A cleaning component for cleaning the filter screen is installed at the upper end of the filter screen 4.

[0033] The air pump 3 generates suction at one end of the straw 2. When the other end of the straw 2 is aligned with the insect, the insect is sucked into the straw 2. After reaching the filter 4, the insect is intercepted and falls down to the collection port, where it falls into the collection bottle 5 and is collected.

[0034] The cleaning component is a brush 6, and the upper end of the straw 2 protrudes upward to form a slide cylinder 16, in which the brush 6 is slidably disposed.

[0035] When some sand, impurities, or insects' legs get caught on the filter screen, the brush 6 is pushed to slide, cleaning the surface of the filter screen 4 and keeping it clear. At the same time, the insects caught on the filter screen 4 can be pushed into the collection port for collection.

[0036] An electromagnet 7 is fixed inside the slide cylinder 16. When the electromagnet 7 is energized, it can drive the brush 6 to slide.

[0037] A metal plate is fixed to the side of the brush 6 near the electromagnet 7. When the electromagnet 7 is energized, the magnet generates an attraction force on the metal plate, causing the brush 6 to approach the electromagnet 7 and avoid the adsorption channel.

[0038] The brush 6 is connected to the slide cylinder 16 via the compression spring 8, and the magnetic force of the electromagnet 7 is greater than the elastic force of the compression spring 8.

[0039] After the electromagnet 7 is de-energized, the brush slides downward under the action of the compression spring 8 to clean the surface of the filter screen 4 and at the same time seal the collection port, which helps prevent insects from escaping.

[0040] A handle 9 is fixed to the rear end of the housing 1. A button 10 is provided on the handle 9 to control the power supply to and from the electromagnet 7 and the air pump 3.

[0041] A switch 11 is fixed inside the slide cylinder. The air pump 3 is electrically connected to the switch 11, and the switch 11 is used in conjunction with the brush 6.

[0042] Button 10 and switch 11 are specifically push-button spring switches, which typically consist of a push-button, a spring, a mounting base, and conductive contacts. The push-button is usually made of plastic or metal and possesses a certain degree of pressing performance and mechanical strength. The spring's function is to allow the button to automatically return to its original position and ensure its elasticity when pressed. The mounting base is used to fix the button and spring, ensuring their positions do not change. The conductive contacts are the key part connecting the circuit; pressing the button connects or disconnects the circuit through the contacts, thus achieving the switch function.

[0043] After pressing button 10, electromagnet 7 is energized, causing brush 6 to come into close contact with electromagnet 7. When brush 6 slides to the top, switch 11 is pressed, which energizes air pump 3 to generate suction and thus suck up insects.

[0044] After pressing button 10, the electromagnet 7 is energized first, which drives the brush 6 to slide. Only after the brush 6 avoids the passage in the straw can the air pump 3 generate suction.

[0045] If the electromagnet 7 and the air pump 3 are energized at the same time, the brush 6 will block the filter 4, affecting the suction power of the air pump. At the same time, the brush 6 will not be able to clear the adsorption channel and collection port in time, resulting in the failure to pick up insects.

[0046] The filter screen 4 is tilted inside the straw 2, and the sliding direction of the brush 6 is consistent with the tilting direction of the filter screen 4.

[0047] The filter screen 4 is tilted so that insects or impurities can fall off under the influence of gravity after reaching the position of the filter screen 4, further preventing impurities and insects from accumulating on the filter screen and affecting subsequent collection.

[0048] The collection bottle 5 has two flaps 12 rotatably connected inside. The flaps 12 are connected to the collection bottle 5 by a coil spring 13. The collection bottle 5 has a push rod 14 that can drive the flaps 12 to rotate.

[0049] The collection bottle 5 is screwed onto the collection port via threads.

[0050] Before the collection bottle 5 is screwed onto the collection port, the spring 13 causes the flap 12 to seal the mouth of the collection bottle 5, at which point the end of the push rod extends out of the collection bottle 5.

[0051] As the collection bottle 5 is screwed onto the collection port, the push rod 14 gradually presses down on the flap 12 as the collection bottle 5 is screwed in, causing the flap 12 to open slowly. When the collection bottle 5 is completely screwed onto the collection port 2, the two flaps 12 form a "V" shape, so that the inside of the collection bottle 5 is connected to the collection port.

[0052] When the two flaps 12 are fully opened, they form a "V" shape, which can prevent some insects from crawling out of the collection bottle 5 and reduce the probability of flying insects flying out.

[0053] The bottom of the collection bottle 5 is threaded with an end cap 15.

[0054] After collecting the insects, the collected insects can be removed by unscrewing the end cap 15, which facilitates subsequent research.

[0055] The front end of the straw 2 is detachably connected to the suction head 17.

[0056] The front end of the suction head 17 is slanted, and the suction head 17 is threadedly connected to the suction tube 2.

[0057] The suction head 17 can also be replaced with a brush head 18.

[0058] The tilted suction head 17 can be aimed more precisely at the target insect, especially when the insect is located in a small gap, depression or irregular surface, it can better fit these special positions and improve the accuracy of collection.

[0059] The brush head 18 can help brush insects that are attached to the surface of objects or are difficult to inhale into the straw. Through the sweeping and agitating action of the brush, the insects are more easily inhaled into the straw.

[0060] A battery cover is threaded to the lower end of the handle 9, and a battery 19 is installed inside the handle 9.

[0061] Specific work process:

[0062] S1: When collecting insects, install the appropriate suction head 17 or brush head 18 according to the collection environment and insect species, and then screw the collection bottle 5 to the collection port position. At this time, the top rod 14 is pressed down by the collection port, and the top rod 14 drives the flap 12 to rotate, so that the flap 12 opens the bottle mouth position of the collection bottle 5.

[0063] S2: After the target insect is detected, press button 10. Electromagnet 7 is energized to generate magnetic force, which attracts brush 6 to come close to electromagnet 7. Spring 8 is compressed to accumulate elastic force. After brush 6 reaches the top, filter screen 4 is exposed, thus avoiding the adsorption channel.

[0064] S3: After the brush 6 reaches the top, press the switch 11 to turn on the power, which will turn on the air pump 3 to generate suction, which will then be used to attract insects through the suction head 17 or the brush head 18.

[0065] S4: After adsorption is complete, release button 10, the electromagnet 7 is de-energized, the spring 8 releases its elasticity, and drives the brush 6 to slide, cleaning the filter screen 4 and sealing the collection port at the same time.

[0066] S5: After collection is complete, unscrew the collection bottle 5 from the collection opening. At this time, the coil spring 13 releases its elasticity, causing the flip plate 12 to rotate and reseal the opening of the collection bottle 5, making it convenient to carry later and helping to prevent insects from escaping.

[0067] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
