Description

An electric mosquito sucker

technical field

The invention belongs to sanitary appliances, and relates to an improved electric mosquito suction device, in particular to an electric mosquito suction device, which can prevent the captured mosquitoes from escaping while efficiently capturing mosquitoes.

Background technique

Present mosquito sucker mainly comprises electric mosquito sucker and artificial mouth suction type mosquito trap. In the routine monitoring tasks of the Centers for Disease Control and Prevention, due to the different lengths of sucking mosquitoes, Culex and Aedes mosquitoes are usually captured by electric mosquito suckers, while Anopheles mosquitoes are usually caught by artificial mouth-suction mosquito traps. For grassroots staff, it is inconvenient to carry two kinds of mosquito catching equipment. The electric mosquito aspirator is powered by batteries and uses the motor to generate suction to catch mosquitoes. However, the suction head of the electric mosquito aspirator on the market has a large diameter. In the gap between mosquitoes, that is, after the power stops, the mosquito aspirator has not come to cover the front cover. When the mosquitoes inhaled escape, the escaped mosquitoes not only cause errors in the monitoring data, but also pose a threat to the safety of the mosquito-catching staff. The suction head of the electric mosquito aspirator is made of ordinary plastic with poor transparency, making it difficult to observe the mosquito inside the suction head. The artificial mouth-suction mosquito trap uses the suction force generated by the staff when they inhale forcefully, and the mosquito trap can be aimed at the mosquitoes to catch mosquitoes. Although the artificial mouth-suction mosquito trap has a special shape suction port to prevent mosquitoes from escaping , but because the suction nozzle is directly inserted into the mouth of the staff, it is difficult to guarantee the hygiene of use, and the suction is greatly affected by the difference in the vital capacity of the staff, and the suction is unstable. The body of the artificial mouth-suction mosquito trap is made of glass. Although it has high transparency and good light transmission, it is easy to break after collision. In actual field application, the artificial mouth-suction mosquito trap has a high loss rate.

SUMMARY OF THE INVENTION

The present invention provides an electric mosquito aspirator to overcome the disadvantages of the existing electric mosquito aspirator, such as easy mosquito escape, poor transparency of the suction head, unstable suction, poor sanitation, and easy breakage of the artificial mouth-suction mosquito trap. The battery, the battery case, the fan, the motor, the motor case, the net, the suction pipe, and the suction head are composed of the battery placed in the battery case, the fan located at the rear end of the motor case, the fan connected to the motor through wires, the battery case located under the motor case, and The front end of the motor housing is connected with the rear end of the suction pipe through the threaded port, and the partition net corresponds to the bayonet in the rear end of the suction pipe through the card slot, which is used to fix the partition net at the rear end of the suction pipe, and the front end of the suction pipe is directly bent and transitioned to the back of the tip.

The suction head has a concave funnel structure, the suction head is inside the suction tube, and the front end of the suction head is the suction head opening.

The diameter of the rear end of the suction pipe is 7 cm, and the diameter of the front end is 3 cm. 2.5 cm).

Both the straw and the suction head are made of the same material, made of highly transparent PP resin material.

The net is stuck on the back end of the straw, the diameter of the net is suitable for the inner diameter of the back end of the straw, the net is provided with 3 card slots, and the inner diameter of the back end of the straw is provided with 3 bayonets, the slots are suitable for the size of the bayonet, and the net passes through The card slot and the bayonet rotation are combined to fix the partition net at the inner diameter of the rear end of the suction pipe.

On the basis of improving the shape of the suction head, the present invention also changes the material of the suction head, and plans to use transparent polypropylene (PP) resin material. PP material has good mechanical properties, and is non-toxic, low relative density, heat resistance, chemical resistance, low price, easy to process and shape, after anti-reflection modification, it has obtained the same level as other transparent materials polycarbonate (PC), Gloss comparable to polyethylene terephthalate (PET) and good transparency. Using transparent PP resin as the suction head of the improved mosquito aspirator not only has high transparency, which is convenient for observing the shape and survival of the inhaled mosquitoes, but also improves the vulnerability of collisions.

The beneficial effect of the present invention is that after changing the shape of the suction head, the mosquitoes can be prevented from escaping during and after sucking mosquitoes, and the shape of the sucked mosquitoes can be better observed and identified after changing the material of the suction head. The electric mosquito aspirator provided by the present invention not only ensures stable electric suction, but also prevents the captured mosquitoes from escaping from the suction port due to the special shape of the suction head, and uses highly transparent PP resin to make the suction head, which is more convenient for clear observation of the captured mosquitoes, and The mosquito aspirator is not easy to break and easy to carry when working on site.

At present, the suction head of the electric mosquito suction device is made of ordinary plastic, which has poor transparency and light transmittance. The whole body of the artificial mouth-suction mosquito trap is made of ordinary glass. Although it has high transparency, it is not resistant to collisions and is easy to break. An electric mosquito aspirator provided by the present invention avoids the defects in shape and material of the two kinds of mosquito traps, improves the shape of the suction head on the basis of maintaining stable electric suction, prevents mosquitoes from escaping, and improves the transparency of the suction head at the same time. Avoid fragility.

Detailed ways

The present invention will be further described in conjunction with drawings and embodiments.

Example 1

Referring to Fig. 1, before catching mosquitoes, the slot 10 on the screen 6 is aligned with the bayonet 11 at the rear end of the suction pipe 7, and then the screen 6 is installed and fixed on the rear end of the suction pipe 7 by rotating the screen 6, and then the suction pipe 7 is aligned with the rear end of the suction pipe 7. After the motor housing 5 spirally connected and installed, you can start to catch mosquitoes. Two No. 1 batteries are used to provide power. After the power is turned on, the motor 4 obtains power to drive the fan 3 to rotate to form a backward wind force, that is, a suction force. Under the action of the suction force, the single mosquito that stops in front of the suction head 8 can be caught. In the process of catching mosquitoes, since both the suction pipe 7 and the suction head 8 are made of highly transparent PP resin material, the basic characteristics and vitality of the captured mosquitoes can be clearly seen. After catching the mosquitoes, first the suction pipe 7 and the motor casing 5 are unscrewed, and then the partition screen 6 is rotated so that the draw-in groove 10 on the partition screen 6 is aligned with the bayonet port 11 on the suction pipe 7 rear end. Captured mosquitoes and other insects aspirated. After use, if the spacer 6, the suction pipe 7 and the suction head 8 are stained with stains, they can be cleaned or soaked with water, and then used again after drying.

Example 2

In Fig. 2, the diameter of the tail end of the suction head 8 is 3 centimeters, and the inner diameter of the opening 9 sunken inward is 0.3 centimeters, (the height of the funnel is 2.5 centimeters). When there is suction, because the width of a single resting mosquito is smaller than the inner diameter of the opening 9, it can be sucked into the suction pipe 7 through the opening 9, but when the mosquito flies in the suction pipe, the wings spread out, and the width of the mosquito is greater than the inner diameter of the opening 9 , the mosquito cannot fly out from the opening 9 in reverse. The special shape of the suction head 8 can effectively prevent the mosquitoes captured in the suction pipe 7 from escaping in reverse.

Example 3

After the electric mosquito suction device of the present invention is started, the fan rotates under the drive of the motor to form a backward suction force, and the suction force formed by the rotation of the electric fan is larger and more stable than that produced by the artificial mouth-suction mosquito trap. , the efficiency of sucking mosquitoes is high, and it can prevent the mosquitoes caught in the suction pipe 7 from escaping when the fan stops rotating. The special shape and specific size of the suction head can only allow a single mosquito to pass through when there is suction, avoiding collisions between mosquitoes or scale damage caused by mosquitoes, and high morphological identification efficiency. The high transparency of suction pipe 7 is convenient to observe the mosquito shape that has caught, carries out preliminary mosquito identification. Partition net 6 can also prevent mosquito from escaping when suction pipe 7 is separated from motor housing 5 after catching.
