Patent & Production

At a glance

What the claims cover, in plain language

Claim 1 describes an insect trap comprising a funnel-shaped display shell and an arc-shaped rain shielding block detachably mounted on top. The shield has spray holes at its bottom and holds a transparent cover. Inside the cover are lamp rods, one end fixed to the shield. A biological induction device is attached below the cover, containing a cylinder, a medicine box with vents, a fan, and a motor. Crucially, the induction device has an external disinfestation device made of an inner arc-shaped conducting ring and an outer arc-shaped conducting ring connected by an annular power grid, which slides relative to the inner ring.

Claim 2 specifies that the funnel shell has water guide holes at the bottom side wall to drain rain. Claim 3 states the lamp rods include UV LED light bars and standard insect trap light bars. Claim 4 details support rods extending from the rain shield to abut the sloped top of the funnel shell. Claim 5 adds a base and mentions the support rods are detachably connected to the funnel shell. Claim 6 introduces a solar cell panel on the support rod, electrically connected to the lamps, motor, and conducting rings.

This is a simplified reading for orientation only. The legal scope is defined by the exact claim wording in the official Chinese document.

What this means for US production

This patent was filed in China and is currently in force. Making or selling this specific design in China requires the owner’s permission. However, the public record shows no US counterpart or foreign family members. Therefore, producing or selling this design in the United States is not restricted by this specific Chinese patent, as patents are territorial.

Two points to settle early:

• Other patents may exist. Pest control devices, particularly those involving electric grids and pheromone dispensers, are a crowded field. There may be existing US patents covering similar combinations of UV light and electrocution mechanisms. A freedom-to-operate (FTO) review is strongly recommended before launching in the US market to ensure no infringement of third-party IP.
• Component sourcing. The solar integration (Claim 6) and specific sliding ring mechanism may have supply chain implications if unique parts are required. Standardizing on common electronic components can reduce risk.

Customization and manufacturing

What can be customized

Things to plan for (US market)

• UL 1559 - The US safety standard for insect-control equipment of the electrocution type. Retail buyers commonly expect a UL or ETL listing to this standard for the electrical assembly, including the grid supply and UV components.
• EPA FIFRA device rules - Insect traps are regulated as devices under FIFRA; labeling and pest-control claims are subject to EPA requirements, and the pheromone lure may have separate registration requirements depending on its active ingredient. Confirm the final classification with a regulatory specialist.
• FCC Part 15 - Electronic components (LED drivers, motors) must comply with EMC standards.
• California Prop 65 - Warnings may be needed for lead or other chemicals in solder or plastics if applicable.

How a project runs

1. Inquiry - Define target pest species, power preference, and volume.
2. Design - Select UV LEDs, size the battery/solar array, finalize grid geometry.
3. Prototype - Build functional samples for waterproofing and kill-rate testing.
4. Pilot run - Small batch production for field testing and safety certification.
5. Production - Injection molding, PCB assembly, final packaging.

Quantities & timeline

Molds for the funnel shell and rain shield are primary tooling costs. Electronics assembly (PCBs, motors) can be sourced from standard suppliers. Safety certification adds significant time upfront.

Production notes

Tooling and process

Likely involves UV-stabilized injection molding for the transparent cover and funnel shell to withstand sunlight. The arc-shaped shield may also be molded or aluminum extrusion if rigidity is prioritized. Metal rings for the grid can be formed from coated steel tube or bent wire.

Cost drivers

UV grade materials for plastics typically increase resin costs. Battery and solar panel components drive BOM cost, especially if high-capacity cells are needed for night operation. Corrosion protection for the electric grid is essential for longevity outdoors.

Prototyping path

Typically, start with 3D-printed parts for the housing to verify fit. Use a coated tube sample for the mounting pole interface. Perform a UV and spray test to check material degradation and sealing. Create a functional sample with live electronics to test the fan and grid voltage.

What we would change before tooling

We would likely need to ensure the sealing surface and gasket compression around the rain shield is robust to prevent water ingress into the motor. Verify shaft and bearing alignment for the fan to minimize noise and wear. Adjust wall thickness and joint design on the funnel to prevent cracking under thermal stress.

Common failure points

Water ingress in electronics is the top risk; potting compounds should be considered for the motor driver. UV degradation and color fade of the plastic cover can reduce light transmission over time. Wind load tipping may occur if the center of gravity is too high; the base weight needs calculation.

Frequently asked questions

How does the dual-mode attraction work?

The trap uses two methods simultaneously. First, UV LED light bars attract insects that navigate by light. Second, a fan disperses pheromones from a medicine box, attracting pests that respond to scent. When insects approach the center, they encounter an electric grid formed by conductive rings, which kills them.

Does it work in the rain?

Yes. The design includes an arc-shaped rain shielding block that covers the lights and electronics. Additionally, the funnel-shaped base has water guide holes that allow rainwater to drain out, preventing flooding and keeping the collection area manageable.

Is it hard to maintain?

No. The rain shield and internal components sit on a sloped top of the funnel shell and are detachable. Users can lift the top section to empty dead insects and refill the medicine box.

Can it run on solar power?

The patent describes a version with a solar cell panel mounted on the support rods, which charges the batteries and powers the lights, motor, and electric grid. This eliminates the need for frequent battery changes or wiring.

What pests does it target?

According to the patent, it is designed for ornamental trees and shrubs. The combination of UV light and a refillable pheromone medicine box allows it to target the flying pest species that respond to the selected light spectrum and lure.

Are there safety concerns with the electric grid?

The grid is located inside the transparent cover and beneath the rain shield, limiting direct contact. However, standard precautions apply: keep away from children and pets, and disconnect power before cleaning. Specific voltage levels are set in design and confirmed on prototypes.

Can this design be made and sold in the US?

The patent was filed in China and is in force there. The public record shows no US counterpart, so this specific Chinese patent does not restrict production or sales in the US. However, other US patents may cover similar technologies, so we recommend a freedom-to-operate check before volume production.

Are you affiliated with the patent owner?

No. IP2M is an independent design and manufacturing service working from the public patent document.
