Example 3

An insect-killing apparatus, which is a mosquito, a moth, various small-sized winged insects, etc., as shown in fig. 7 to 9, comprising: the insect treatment device 2 is provided with a bottom plate 9, and a circular air suction opening 201 is formed in the center of the bottom plate 9. A suction opening 5 is provided around the insect treatment device 2. A flow guide device 14 is arranged inside the insect treatment device 2, the flow guide device 14 is composed of a plurality of flow guide parts, the flow guide parts extend from the suction opening 5 to the inside of the insect treatment device 2 along the airflow direction, and the extending direction of the flow guide parts is basically tangential to the circumferential direction of the suction opening 201. An air flow passage 15 is formed between the other end of the flow guide device 14 opposite to the suction port 5 and the suction port 201. The air suction opening 201 is provided with a flow guide filtering device 8.

When the suction port 201 forms negative pressure, air enters the airflow passage 15 from the suction port 5 and the flow guide device 14, and the air forms rotating airflow in the airflow passage 15; the sucked insects rotate with the airflow.

In the insect extermination device in this embodiment, negative pressure is generated by the suction opening 201 in the bottom plate 9, and insects around the insect extermination device are sucked into the interior of the insect treatment device 2 through the suction opening 5. Make at the inside rotatory air current that forms of insect treatment device 2 through guiding device 14, the insect is rotatory in insect treatment device 2's inside along with rotatory air current, and under the effect of the rotatory air current of a period of time, the insect can be air-dried and die, kills the insect through the physical means, can kill the insect effectively on the basis of not producing harm to the human body.

At the upper end of extraction opening 201, the inboard of insect treatment device 2 is equipped with water conservancy diversion filter equipment 8, and water conservancy diversion filter equipment 8 can play water conservancy diversion and filtering action. After the outside air enters the insect treatment device 2 through the diversion filter device 8, the air flow is discharged along the air suction opening in the direction opposite to the insect treatment device 2 while forming the rotating air flow. The sucked insects will also move along with the airflow after rotating in the insect treatment device and then move towards the direction of exhausting the airflow, and the diversion filter device 8 isolates the insects through the filtering effect and prevents the insects from passing through the air exhaust port 201. The insects are prevented from being broken by the negative pressure generating device 1 arranged at the other side of the air exhaust port 201 relative to the insect processing device 2, the formed paste is attached to the negative pressure generating device 1, and the released viruses and bacteria can harm the body health of the user.

The flow guide device 14 is formed by arranging flow guide parts at intervals, after air flows through the flow guide device 14, the air flow direction is tangent to the air flow channel 15, and the air flow rotates in the air flow channel 15.

The air entering from the suction opening 5 is redirected by the deflector 14 formed by a deflector element tangential to the air flow passage 15 to flow in a direction tangential to the air flow passage 15, thereby forming a rotating air flow, with which the insects entering the insect treatment device 2.

The insect killing apparatus further comprises: the collecting device 13 may be disposed above the airflow passage 15, may be disposed outside the airflow passage 15 in the radial direction, may be disposed at any position below the airflow passage 15, or a combination thereof.

After the insects enter the insect treatment device 2, the insects stay inside the insect treatment device 2, and for the convenience of cleaning, a collecting device 13 is arranged inside the insect treatment device 2 and used for collecting the insects entering the insect treatment device.

As shown in fig. 9, at least a portion of the guide filter device 8 extends upward in a vertical direction. An air flow adjusting area 81 is arranged on the side wall of the diversion filtering device 8, and the height of the rotating air flow in the air flow channel in the vertical direction is adjusted through the air flow adjusting area 81 according to the arrangement position of the collecting device 13.

The installation filter equipment 8 has avoided the insect to be inhaled the insect and has killed the device after, along the inside that the vertical direction of extraction opening 201 got into negative pressure generating device 1 with the air current, leads to the insect to adhere to the fan surface, is beaten into the thick liquid by the blade, gives out harmful gas polluted air, influences the health to, reduce the difficulty of clean negative pressure generating device 1.

The diversion filtering device 8 can be realized by installing a flat-plate type filter screen at the air suction port 201. However, when the insects are sucked into the insect killing apparatus, the insects are gradually gathered toward the center of the air suction opening 201 along with the rotating airflow, the rotating speed of the airflow is gradually reduced along with the rotating airflow approaching the center of the air suction opening 201, and meanwhile, the center of the air suction opening 201 has a downward attraction force, so that most of the insects are finally gathered in the center area of the air suction opening 201.

For the above reasons, it is preferable that the guide filter device 8 is formed such that at least a portion of the guide filter device 8 extends upward in the vertical direction.

By adopting the above technical scheme, after the guide filter device 8 extends upwards along the axial direction, the surface area of the guide filter device 8 is far larger than that of a flat filter screen, so that the total area of the air inlet holes 801 is far larger than that of the air suction opening 201, the attraction force at the air suction opening 201 is reduced, insects rotate along the periphery of the guide filter device 8 as far as possible when rotating along with the air flow, the possibility that the insects stay in the central area of the guide filter device 8 is reduced, the insects are quickly dried and killed, and the effect of killing the insects is improved.

Specifically, the air inlet area 82 of the diversion filter device 8 is formed at the part of the wall plate of the diversion filter device 8, where the air inlet holes 801 are arranged, and the air inlet area 82 is used for filtering insects so that the insects cannot enter the diversion filter device 8 and are attached to the negative pressure generating device 1. The other part of the wall of the guide filter device 8, which is not provided with air inlet openings, is an air flow conditioning zone 81.

In this embodiment, when the collecting device 13 is disposed above the airflow channel, when the airflow rotates in the airflow channel, because the airflow adjusting region 81 has no air inlet holes, the airflow rotates and rises above the axial direction of the flow-guiding filtering device 8 under the action of centrifugal force, and the insects are driven to move upwards until entering the inside of the collecting device. The height of the air flow adjustment region 81 increases as the height of the collection device 13 and the suction opening increases.

The air inlet area 82 is communicated with the air suction opening 201. The air flow is drawn out from the suction opening 201 through the intake air region 82 while rotating in the air flow passage. Meanwhile, the insects are blocked when moving upward to the air intake region 82 along with the airflow, cannot move toward the air exhaust port 201 along with the airflow, and continue to move upward along with the airflow until entering the first storage groove 1311.

The flow guide member is at least one of a plate-like member and a tubular member extending from the suction port 5 toward the inside of the airflow passage.

The guide member may be in various forms as long as it functions to form the air flow sucked from the suction port 5 into a rotating air flow. Preferably, a plate-like member or a tubular member, or a combination thereof, may be used.

In the present embodiment, as shown in fig. 7 and 8, the flow guide member is a plate-like member, a plurality of plate-like members extend from the suction port 5 to the suction port 201, and the extending direction of the plate-like member is tangential to the suction port 201, that is, the extending direction of the plate-like member is tangential to the air flow passage.

As shown in fig. 5, the collecting device 13 includes:

the first storage groove 131 has a storage groove opening 133 at an end of the first storage groove 131 facing the wind. An air flow hole 134 is formed in a wall plate of the first receiving groove 131 on a side opposite to the air suction port 201.

The insects sucked into the air flow channel rotate in the air flow channel with the rotating air flow, and when rotated to the receiving groove opening 133, the insects enter the first receiving groove 131 through the receiving groove opening 133. In the present embodiment, the collecting device 13 is disposed above the air flow passage, and the air flow adjusting region 81 having a certain height is disposed at the lower portion of the guide filter device 8, so that the whirling air flow rotates in the air flow passage 15 and flows upward, and therefore, the storage groove opening 133 is disposed at the bottom of the first storage groove 131.

As the number of insects increases, the insects block the storage groove opening 133, so that a closed space is formed inside the first storage groove 131, in order to make the insects effectively fill the first storage groove 131, a plurality of airflow holes 134 are provided on a wall plate of the first storage groove 131 opposite to the air suction opening 201, a part of the rotating airflow enters the first storage groove 131 from the storage groove opening 133, and a part of the rotating airflow enters the first storage groove 131 from the airflow holes 134 to discharge the air inside the first storage groove 131, so that the insects entering from the storage groove opening 133 along with the airflow continue to move to the inside of the first storage groove 131, thereby avoiding blocking at the storage groove opening 133.

The other end of the first receiving groove 131 opposite to the receiving groove opening 133 is provided with a baffle 136, so that although the air flow inside the first receiving groove 131 forms a flowing air flow, the baffle 136 makes a part of the air flow reversely, and has a blocking effect on the air flow entering from the receiving groove opening 133, therefore, a ventilation plate 135 with a plurality of through holes is arranged inside the first receiving groove 131 to divide the first receiving groove 131 into a first space 1311 and a second space 1312 which are communicated, so that the first space 1311 and the second space 1312 form two chambers which are communicated with each other and independent of each other. The airflow in the airflow path partially enters the first space 1311 from the receiving groove opening 133 and the airflow hole 134, and partially enters the second space 1312 through the airflow hole 134, and the airflow inside the second space 1312 is discharged to the outside of the collecting device 13, so that the airflow in the first space 1311 continues to flow toward the second space 1312, thereby moving the insects to the ventilating board 135 to fill the first space 1311.

The collecting device 13 further comprises:

a second receiving groove 132, the second receiving groove 132 communicating with an outer periphery of the insect treatment device 2, and the second receiving groove 132 being provided near the suction port 5.

The second receiving groove 132 is used to receive a bait, and the smell emitted from the bait is emitted to the outside through the insect treatment apparatus 2 to attract insects to be close to the insect extermination apparatus. By disposing the second receiving groove 132 close to the suction opening 5, the insects can be further close to the suction opening, and the suction effect of the insects can be improved.

As an example, the first receiving groove 131 and the second receiving groove 132 may be integrally formed, and the middle is separated by a baffle 136, and the other end of the second receiving groove 132 opposite to the baffle 136 is connected to the receiving groove opening 133 to form the ring-shaped collecting device 13 around the suction opening 201.

As an example, as described above, the longer the length of the first receiving groove 131, the less the insect collecting effect, and the ventilation plate 135 is required to divide the first receiving groove 131 into two spaces, i.e., the first space 1311 and the second space 1312, so that in this embodiment, a plurality of first receiving grooves 131 may be provided to shorten the length of the first receiving groove 131. Preferably, the plurality of first receiving grooves 131 and the plurality of second receiving grooves 132 are spaced apart and connected to each other to form one ring-shaped collecting device 13.

Example 4

The insect-exterminating apparatus of the present embodiment is different from that of embodiment 3 in that the collecting means 13 is disposed below the airflow passage, and therefore, the storage groove opening 133 is disposed above the first storage groove 131, as shown in fig. 10.

In the present embodiment, since the collecting device 13 is disposed below the airflow path, when the insects enter the interior of the insect treatment device 2 from the suction opening 5, they directly enter the first receiving groove 131 through the receiving groove opening 133 with the rotating airflow. Similarly, an air flow hole 134 is provided in a side wall plate of the first receiving groove 131 opposite to the air suction port 201. While the rotating airflow rotates in the airflow passage 15, a negative pressure is generated at the airflow hole 134 of the first receiving groove 131, so that the insects entering from the receiving groove opening 133 continue to move toward the inside of the first receiving groove 131, thereby preventing the insects from blocking the receiving groove opening 133

Example 5

The insect extermination device of this embodiment is different from that of embodiment 3 in that, as shown in fig. 11, the collection device 13 is disposed outside the circumferential direction of the air flow passage, and therefore, the storage groove opening 133 is provided on the side wall plate of the first storage groove opposite to the air suction opening 201.

When the insects enter the insect treatment apparatus 2 from the suction port 5, the rotating airflow rotates in the airflow path 15 to generate a centrifugal force on the storage groove opening 133 of the first storage groove 131, and the insects directly enter the first storage groove 131 through the storage groove opening 133 with the rotating airflow under the action of the centrifugal force. Meanwhile, the whirling airflow also generates a centrifugal force to the inside of the first receiving groove 131 through the airflow hole 134, and the insects continue to move to the inside of the first receiving groove 131 under the centrifugal force, thereby preventing the insects from blocking the receiving groove opening 133.

Example 6

The insect-exterminating apparatus of this embodiment is different from that of embodiment 3 in that two or more flow guide means including at least a first flow guide means 14 are provided in the insect treatment apparatus 2, and that, as in embodiment 3, a first suction port 5 is provided in a side wall of the insect treatment apparatus 2 and extends from the first suction port 5' toward the suction port 201 in a direction tangential to the air flow path through a plurality of plate-like members.

According to the specific situation, it is also possible to use a plate-like or tubular part for both the flow guiding part of the first flow guiding device 14 and the flow guiding part of the second flow guiding device 14'. Other forms of flow guide members may be used in addition to the plate-like member and the tubular member, as long as they function to form the airflow sucked into the airflow passage into the swirling airflow.

Example 7

The difference between this embodiment and the above embodiments is that as shown in fig. 14 and 15, the insect treatment device 2 includes a housing 202, the housing 202 includes a lower cover 2021 and a cover 2022, the bottom plate 9 is disposed at the bottom of the lower cover 2021, and the cover 2022 is fastened to the outside of the diversion filter device 8.

The suction port 5 "is an opening provided in the lower cover 2021, and the cover 2022 communicates with the suction port 5".

As shown in fig. 16, a deflector 14 "is provided inside the lower shroud 2021, the deflector 14" is formed by two arc-shaped plate-like members connected to each other, and the deflector 14 "is connected to the first side wall of the lower shroud 2021. One of the two plate-like members is arranged concentrically with the suction port 5 ", and the other plate-like member is arranged concentrically with the cover cylinder 2022. A communication passage between the suction opening 5 ″ and the mosquito treatment device 2 is formed between the junction of the two plate-like members and the second side wall of the lower case 2021 opposite to the first side wall.
