Description

TECHNICAL FIELD

[0001] The utility model belongs to mosquito killing device field, specifically, relate to a kind of suction type electric mosquito gun. BACKGROUND

[0002] In hot summer, mosquito is not only the annoying trouble, but also the transmission medium of multiple diseases. The itching feeling brought by mosquito bite is unbearable, and it affects normal life and rest. More seriously, mosquito can transmit dengue fever, malaria, yellow fever and other viruses, which pose a great threat to human health, especially in warm and humid environment, the risk of disease transmission is higher, so mosquito control is particularly important.

[0003] Although the conventional electric mosquito swatter is widely used and can kill mosquitoes to some extent, it has many design defects. First, the size of the electric mosquito swatter is usually large, and it is not flexible to operate. When the mosquito stays in the corner of the cabinet, the corner of the wall or the roof, the user needs to frequently adjust the angle of the electric mosquito swatter to aim at the mosquito for capture. However, due to the flexibility of the mosquito, many times they will fly away from the side or opposite direction of the electric mosquito swatter, resulting in failure to capture the mosquito. Especially in some narrow or difficult-to-access areas, such as behind the sofa, furniture gaps or high ceiling, the bulky design of the electric mosquito swatter makes it extremely difficult to operate, and the use efficiency is low.

[0004] Secondly, the high-voltage electric net of the conventional electric mosquito swatter is usually exposed, which has certain safety hazards. The working principle of the traditional electric mosquito swatter is to block the flight path of the mosquito by high-voltage electric net, so that the mosquito is instantaneously electrocuted after contacting the electric net. However, due to the large area of the electric net and the absence of protective barriers, fingers or other parts are likely to accidentally touch the high-voltage electric net during use, resulting in electric shock to the user, which may cause skin burns. This design poses a potential safety risk to children or people unfamiliar with the use of electrical appliances.

[0036] The utility model will be further described in detail in combination with the drawings.

[0037] Please refer to Figures 1-6 shown in the embodiment, a suction type electric mosquito gun is provided, which comprises a gun barrel 2, both ends of the gun barrel 2 are open structures, one end is an air inlet and the other end is an air outlet, and an electric mosquito assembly, an air suction assembly 6 are sequentially arranged in the gun barrel 2 from the air inlet to the air outlet;

[0038] A handle 3 is located below the gun barrel 2, the handle 3 is a hollow structure, a switch 13 is arranged on the outside of the handle 3, and a circuit system is arranged in the inside of the handle 3.

[0039] A power supply lead 14 is electrically connected between the circuit system, the switch 13, the electric mosquito assembly and the air suction assembly 6.

[0040] It also comprises a mosquito attracting lamp 7, which is installed on the inner wall of the gun barrel 2 near the air inlet on one side, and is electrically connected between the circuit system and the mosquito attracting lamp 7.

[0041] It should be noted that: the air suction assembly 6 is used to realize the air suction of the air inlet of the gun barrel 2 and the air blowing of the air outlet, and the mosquito attracting lamp 7 is used to attract mosquitoes by emitting light through the ultraviolet diode lamp. The mosquito attracting lamp 7 adopts an ultraviolet diode lamp.

[0042] Compared with the ordinary electric mosquito swatter, the handheld suction type electric mosquito gun has the following advantages:

[0043] First, the mosquito is actively sucked to prevent the mosquito from escaping. The handheld suction type electric mosquito gun actively sucks the mosquito into the electric shock by relying on the suction force generated by the fan rotation, preventing the mosquito from escaping. The ordinary electric mosquito swatter has no suction force, mainly relies on the large area of the electric mosquito swatter to block the flight path of the mosquito, and makes the mosquito fly into the electric shock. When the mosquito does not fall on the flat wall surface or the cabinet surface, the mosquito can easily fly to the opposite direction or the side of the electric mosquito swatter and escape.

[0044] Second, it is convenient to align the mosquito operation. The handheld suction type electric mosquito gun is designed as a small gun-shaped structure, which is convenient to adjust the gun mouth to point to the mosquito during use, and can automatically suck the mosquito at a certain distance from the mosquito, preventing the mosquito from escaping. The ordinary electric mosquito swatter needs to be parallel to the wall surface where the mosquito is located when used, and then needs to be approached. After the mosquito flies up, it needs to be hit by the net to be electrocuted. The operation is not convenient, especially when electrocuting the roof mosquito, it needs to stand on a stool, hold the electric mosquito swatter horizontally, and approach it. It is difficult to operate. If the mosquito does not move or fly to the electric mosquito swatter, it cannot be electrocuted.

[0045] Third, the embedded design of the electric mosquito net improves the safety. The handheld suction type electric mosquito gun installs the high-voltage electric mosquito net in the barrel inside the gun, at a certain distance from the entrance, to prevent people, especially children, from accidentally touching the high-voltage electric net with their fingers and being electrocuted. In order to make the mosquito fly in, the ordinary electric mosquito swatter increases the area of the electric net, which is exposed outside, and is easily electrocuted by accidentally touching the fingers during operation.

[0046] In the embodiment, the circuit system includes an electric mosquito module 8, a voltage conversion module 9, a charging port 11, a battery pack 12, and a charge and discharge module 10 with a TYPE-C connector. The electric mosquito module 8 is installed above the inner wall of the handle 3, the voltage conversion module 9 is installed at the middle part of the inner wall of the handle 3, the charge and discharge module 10 and the battery pack 12 are both installed below the inner wall of the handle 3, the charging port 11 is located on one side of the outer wall of the handle 3, and the position of the TYPE-C interface of the charge and discharge module 10 corresponds to the position of the charging port 11.

[0047] The electric mosquito gun adopts the active suction type design, relies on the suction force generated by the fan rotation, and automatically sucks the mosquito at a certain distance from the mosquito, preventing the mosquito from escaping. The ordinary electric mosquito swatter has no suction force, mainly relies on the large area of the electric mosquito swatter to block the flight path of the mosquito, and makes the mosquito fly into the electric shock. When the mosquito does not fall on the flat wall surface or the cabinet surface, the mosquito can easily fly to the opposite direction or the side of the electric mosquito swatter and escape.

[0048] The utility model discloses an electric mosquito gun adopts gun -like structure design, and the size is small, and the quality is light, and the shape is gun -like, and convenient to grasp and operate use, and it is easy to adjust the gun mouth direction alignment mosquito, with initiative suction function, therefore, can quickly capture the mosquito in the flight or in the stillness. But the ordinary electric mosquito clap needs to be parallel mosquito wall surface and then approaches when using, and mosquito needs to hit the electric net after flying up to be electrocuted, and the operation is inconvenient, especially when electrocuting the mosquito on the roof, needs to stand on the stool, holds up the electric mosquito clap and approaches, and the operation use is very inconvenient. Furthermore, ordinary mosquito killing appliance, such as mosquito killer lamp, belongs to the mosquito of waiting for the rabbit type, and the size is generally larger, and is arranged in the fixed position, and the mosquito is attracted through the light, and then is sucked or electrocuted, and the active mosquito catching is inconvenient.

[0049] The utility model discloses an electric mosquito gun adopts the bucket -shaped structure design, and the gun bucket is the front and rear opening, and the middle hollow is the bucket -shaped structure of the seal of four all around, and the gun bucket front suction mouth adopts the horn -shaped opening design, and installs the fan in the inside to increase the air flow effect. But the invention and utility model of the mosquito killing appliance with suction design similar to the proposal, generally installs the fan or the electric mosquito clap and fan simple combination in the ordinary electric mosquito clap middle or rear, adopts the open design, and the airflow is more divergent, and under the same fan working condition, compared with the utility model, its directionality and suction force are poor.

[0050] The utility model discloses an electric mosquito gun electric mosquito net is in -bedded design, improves the security of use. Install high -voltage electric mosquito net in the gun bucket inside, and the distance is a certain distance from the air inlet, prevent personnel from accidentally touching the high -voltage electric net with the finger, and be electrocuted and be injured. But the ordinary electric mosquito clap increases the electric net area for letting the mosquito fly into, and is exposed outside, and it is easy to be electrocuted because of accidentally touching with the finger when operating

[0051] The electric mosquito assembly of the embodiment includes a coarse mesh electric net 4 close to the mosquito attracting lamp 7 and a fine mesh electric net 5 away from the mosquito attracting lamp 7, and a space is formed between the coarse mesh electric net 4 and the fine mesh electric net 5.

The fine mesh electric net 5 is a square hole with a size of 2.9 mm*2.9 mm.

[0052] The air inlet of the gun barrel 2 is in a horn mouth 1 structure. The front end opening size of the horn mouth 1 is larger than the rear end opening size, forming a tapered structure, so as to better concentrate the airflow direction and improve the mosquito adsorption efficiency.

[0053] The size of the trumpet mouth 1 is 8 cm*8 cm at the front end, 5 cm*5 cm at the rear end, and the distance between the front end opening and the rear end opening is 3 cm. The size of the gun barrel is 5 cm*5 cm*20 cm, and the size of the handle 3 is 4 cm*4 cm*15 cm. The handle 3 is installed directly below the gun barrel, with a distance of 13 cm from the air inlet of the gun barrel and a distance of 5 cm from the air outlet of the gun barrel. Two electric mosquito nets are arranged in the gun barrel 2, wherein the distance between the coarse mesh of the electric net and the air inlet of the gun barrel is 5 cm, the distance between the two electric mosquito nets is about 0.4 cm, the distance between the electric mosquito net and the fan is 4 cm, the thickness of the fan is about 3 cm, the distance between the fan and the air outlet is 10.6 cm, and the ultraviolet diode lamp is installed at the air inlet 4 cm away.

[0054] In this embodiment, a plurality of through holes are formed at the connection between the gun barrel 2 and the handle 3 for the power supply wires 14 to pass from the handle 3 into the gun barrel 2. In addition, the power supply wires 14 are arranged along the inner walls of the gun barrel 2 and the handle 3, thereby realizing compact and safe layout of the overall circuit.

[0055] In this embodiment, the battery pack 12 adopts two parallel battery packs 12, and the output voltage is 3.7 V. The positive and negative poles of the two parallel battery packs 12 are respectively connected to the input end of the charge and discharge module 10, for providing 3.7 V voltage for the entire circuit. The charge and discharge module 10 is connected to an external power supply through a TYPE-C interface, for providing charging function for the battery pack 12. The output positive and negative poles of the charge and discharge module 10 are respectively connected to the input end of the voltage conversion module 9. The voltage conversion module 9 has three power supply wires 14, wherein the first output of the voltage conversion module 9 is connected to the air suction assembly 6 for supplying power thereto. The second output of the voltage conversion module 9 is connected to the mosquito attracting lamp 7 after limiting current through a series resistor, for supplying power thereto. The third output of the voltage conversion module 9 is connected to the electric mosquito module 8, for supplying power thereto and boosting the output to high voltage state, and connecting to the electric mosquito assembly. A high-voltage electric field is formed between the two electric nets for electrocution and killing mosquitoes.

[0056] The voltage conversion module receives 3.7 V voltage, boosts it to 12 V, and connects the positive and negative output ends to the positive and negative poles of the air suction assembly 6 for supplying power to the air suction assembly 6 module.

[0057] The voltage conversion module 9 receives 3.7 V voltage, directly connects the input end to the output end, connects the positive pole to the positive input end of the ultraviolet lamp through a series resistor, and directly connects the negative pole of the voltage conversion module 9 to the negative input end of the mosquito attracting lamp. The mosquito attracting lamp receives 3.7 V voltage and normally works after limiting current through a resistor.

[0058] The voltage conversion module 9 receives 3.7 V voltage, directly connects the input end to the output end, and connects the positive and negative poles to the input end of the electric mosquito module 8. The electric mosquito module 8 receives 3.7 V voltage, boosts it to 2000 V, connects the coarse mesh electric net 4 through the high-voltage positive output, and connects the fine mesh electric net 5 through the high-voltage negative output, to form a high-voltage electric field for electrocution and killing mosquitoes.

[0059] The switch 13 is connected to the positive output line of the charge-discharge module 10 through the power supply wire 14, and the whole circuit is controlled by the switch 13.

[0060] It should be noted that the air suction assembly 6 is a fan, which uses a common cooling fan to provide wind power. The fan size is 4cm*4cm*2.8cm, 12V, 0.6A, and the blowing end is directed towards the tail of the gun barrel 2 to generate suction at the front end of the gun barrel 2;

[0061] The model of the charge-discharge module 10 is TP4056, which provides a 5V voltage output to the 18650 battery pack 12 for charging, and has a built-in battery charge and discharge protection function. The voltage of the charge-discharge module 10 is adjusted by the voltage conversion module 9 to adapt to the power requirements of the fan and the electric mosquito net and the mosquito trapping lamp.

[0062] The model of the voltage conversion module 9 is XL6009, which boosts the voltage of the battery pack 12 from 3.7V to 12V to power the fan;

[0063] The model of the electric mosquito module is XKT203-55, which boosts the voltage of the battery pack from 3.7V to 2000V;

[0064] Further, the charge-discharge module 10 charges the battery pack 12 and has a charge and discharge protection function.

[0065] When in use, the gun barrel 2 and the handle 3 need to be connected together first to ensure that they are stable and the circuit can be normally connected. When installing the coarse mesh electric net 4 and the fine mesh electric net 5, attention should be paid to the distance between them, which should not be too large or too small, and it is best to be close to the length of the mosquito, so that the mosquito can be stopped and the electric shock effect can be ensured. The coarse mesh electric net 4 needs to be installed on the outside, and the fine mesh electric net 5 needs to be installed on the inside. This design of the front coarse and the rear fine electric net not only effectively guides the mosquito into the area between the two nets, but also uses the opening of the coarse mesh electric net to preliminarily intercept the mosquito, and the fine mesh electric net further limits the activity range of the mosquito to avoid its escape from the electric net area.

[0066] When the mosquito is sucked into the area between the two nets, the reasonable distance between the two nets matches the body length of the mosquito, so that its body touches the two nets and triggers high-voltage current for instantaneous electric shock. The design of the coarse net can ensure that the mosquito is not blocked when it is sucked in, and the fine net provides further interception in the rear to ensure that the mosquito cannot fly back or escape. This double-net structure not only improves the success rate of mosquito killing, but also avoids the failure of capture caused by the mosquito not touching the electric net, so as to achieve the effect of fast and efficient mosquito killing.

[0067] The utility model is not limited to the above-mentioned embodiment, any person should know the structure change made under the inspiration of the utility model, any technical scheme with the same or similar to the utility model falls into the protection scope of the utility model. The utility model is not described in detail the technology, shape, structure part is the known technology.
