The power grid component 100 includes a power grid separator 110 and a light emitting device 120. The power grid separator 110 is a frame formed by connecting a plurality of light-transmitting strips 101. The power grid separator 110 is provided with a light-transmitting strip light-entering end 1011 at the circumferential side of the power grid separator 110. The power grid separator 110 is also provided with a light-transmitting strip bending connection portion 102. The light-transmitting strip bending connection portion 102 is the place where the light-transmitting strips 101 are connected at an angle. It can be understood that the angle connection means that the light-transmitting strips 101 are connected to form an angle, and the angle does not include the case of a straight angle. The light emitting device 120 is arranged on the outer peripheral side of the grid separator 110, and the light emitting device 120 is provided with a light emitting body 121 opposite to the light incident end 1011 of the light-transmitting strip. The light emitting body 121 can emit light toward the light incident end 1011 of the light-transmitting strip, and the light can pass through the light-transmitting strip 101 to guide the light to the bending connection part 102 of the light-transmitting strip, so that a light-emitting enhancement point is formed at the bending connection part 102 of the light-transmitting strip.

[0032] In the above structure, the grid separator 110 is configured as a frame composed of light-transmitting strips 101, and the light-emitting body 121 of the light-emitting device 120 emits light to the light-transmitting strip light-entering end 1011 of the frame, so that the light is introduced into the light-transmitting strip bending connection part 102 through the light-transmitting strip 101. Since the light-transmitting strip bending connection part 102 is the place where the light-transmitting strips 101 are connected at an angle, the light path forms a concentrated light at this position, so that the light has a stronger brightness at this position, that is, a light-emitting enhancement point is formed. The light-emitting enhancement point concentrated at a local position has a relatively better brightness, thereby better attracting mosquitoes.

[0033] In the embodiment, the grid separator 110 includes an outer frame 111 and a main frame 112. The outer frame 111 is a frame formed by the light-transmitting strips 101. The main frame 112 is arranged in the outer frame 111. The main frame 112 includes a plurality of connected light-transmitting strips 101.

The light-transmitting strip light-incoming end 1011 is the end of the light-transmitting strip 101 on the peripheral side of the main frame 112. With the above structure, the overall structure of the grid separator 110 is stable, and the structure facilitates the introduction of light into the interior of the main frame 112. Of course, it is conceivable that the grid separator 110 can also adopt other suitable structures without being limited to the above embodiment, for example, the grid separator 110 is a structure with only the main frame 112.

[0034] In the embodiment, the light-transmitting strip 101 on the circumferential side of the main frame 112 is connected to the outer frame 111 to form a circumferential bending connection part 103.

The light-emitting body 121 is configured to emit light to the circumferential bending connection part 103 and enable the circumferential bending connection part 103 to form a light-emitting enhancement point. With the above structure, the circumferential bending connection part 103 can be further formed at the place where the outer frame 111 and the main frame 112 are connected. The circumferential bending connection part 103 can also bend the light path and form a gathering, so that a light-emitting enhancement point can also be formed at the circumferential bending connection part 103, thereby increasing the mosquito-attracting area and improving the mosquito-attracting effect. In some embodiments, the circumferential bending connection part 103 can also be understood as a special light-transmitting strip bending connection part 102.

With the above structure, a plurality of light-transmitting strip bending connection portions 102 can be formed on the central frame 1121, thereby forming a plurality of light-emitting reinforcement points distributed in a ring on the central frame 1121, which is conducive to enhancing the mosquito-attracting effect.

[0037] In the embodiment, the central frame 1121 is annular, which may be a racetrack, a circular ring, or other annular shapes. Figure 4 In the figure, there is a light-transmitting strip group indicated by a hatching line; and the outer peripheral frame 111 is a light-transmitting strip group without a hatching line indication.

[0038] In the embodiment, part of the peripheral connector 1122 is formed by connecting two light-transmitting strips 101 connected end to end, and the light-transmitting strips 101 connected end to end form a light-transmitting strip bending connection part 102 at the connection point. With the above structure, it is possible to further increase the light-emitting reinforcement points on the peripheral connector 1122, thereby improving the mosquito-attracting effect. It is conceivable that in some embodiments, all the peripheral connectors 1122 can also be configured to have a structure with multiple light-transmitting strips 101. Of course, it is conceivable that the light-transmitting strips 101 provided in the peripheral connector 1122 are not limited to two, for example, one or more than two, and can be specifically configured according to actual conditions.

[0039] In the embodiment, the outer surface of the outer frame 111 is provided with a receiving groove 1111 opposite to the light incident end 1011 of the light-transmitting strip, and the light-emitting body 121 is received in the receiving groove 1111 , thereby facilitating the gathering of light and accommodating and protecting the light-emitting body 121 .

[0040] In the embodiment, the light emitting device 120 is a light strip, the light emitting body 121 is a lamp bead arranged on the light strip, and the light strip is attached to the outer peripheral surface of the peripheral frame 111. The light emitting device 120 is a light strip, which has a simple structure and is convenient to be fixed to the peripheral frame 111. It is conceivable that the light emitting device 120 can also be other structures, such as lamp beads or lamp panels connected by wires.

[0041] In the embodiment, the light-emitting body 121 is configured as a UV lamp bead, which can emit UV light and has a good mosquito-attracting effect; of course, it is conceivable that the light-emitting body 121 can also adopt a structure that emits other suitable light, and the specific configuration can be based on actual conditions.

[0042] In the embodiment, both sides of the mid-plane A in the length direction of the power grid assembly 100 are provided with light-transmitting strip bend connecting parts 102, and both sides of the mid-plane B in the width direction of the power grid assembly 100 are provided with light-transmitting strip bend connecting parts 102. With the above structure, luminous enhancement points can be fully formed at various positions, the luminous enhancement points are numerous and reasonably distributed, and the luminous enhancement points can complement each other at different observation angles, thereby forming a multi-angle mosquito trap.

The central axis of the handle portion 210 along the length direction coincides with the mid-dividing plane B, and the light-transmitting strip bending connection portions 102 on both sides of the mid-dividing plane B are symmetrically arranged about the mid-dividing plane B. In some embodiments, the central axis of the handle portion 210 along the length direction may also coincide with the mid-dividing plane A, and the light-transmitting strip bending connection portions 102 on both sides of the mid-dividing plane A are symmetrical about the mid-dividing plane A. With the above structure, when the electric mosquito swatter is supported on the external support surface by the support base 300, the mosquito-attracting effect of the power grid component 100 on both sides of the handle axis is equivalent, so that mosquitoes are evenly attracted and killed on both sides to avoid local accumulation of mosquitoes.

With the above structure, mosquitoes can be killed by the discharge between the first electrode net 130 and the second electrode net 140, and because the power grid separator 110 is located between the two second electrode nets 140, the power grid separator 110 is split into two parts and clamps the first electrode net 130, so that the light-emitting enhancement point is located on the inner side of the power grid, so as to facilitate the induction of mosquitoes into the inner side of the power grid for killing.
