The invention relates to a method and to a device for repelling insects by means of a two-channel pulse pattern transmitter (1), which, by means of the integrated antennas (34a, 34b), emits two electromagnetic waves (35a, 36a) phase-shifted against each other by 180 degrees and modulated and pulsed with the pulse patterns (24, 23) and produces two electromagnetic fields (35b, 36b), which act on insects (45) located in the radiation range (76) in such a way that the neurons (50, 53) located in the supraesophageal and subesophageal ganglia (48, 51) and the sensory neurons (65), the motor neurons (66), and the interneurons that exist in the central and peripheral nervous system (63, 64) of bloodsucking insects (45) are influenced in such a way that the signals and reflexes produced by the neurons trigger abnormal behaviors that put the insects into an inactive state such that bloodsucking insects cannot penetrate the skin of humans and thus cannot suck blood.

An insect suppression device, and further relates to a self-moving device, a charging station, and an automatic working system that are mounted with the insect suppression device are provided. The self-moving device moves in a working area, performs a working task, and includes: a body and a movement module that is mounted on the body and drives the self-moving device to move. The self-moving device includes: an insect suppression device, mounted to the body, and a control module, controlling the movement module to move and controlling the insect suppression device to work. The beneficial effects of the present invention are as follows: The self-moving device can move autonomously in the working area and perform an insect suppression task, and has a wide coverage area, flexible work, and high efficiency, so that automatic control can be implemented, thereby freeing a user from the harassment of insects.

A device for ionising air includes a case, in which there are a blower, which includes a rotor to generate a pulsed airflow and an exhaust pipe to channel this flow; a device for producing ions, which includes a high-voltage electrical generator; an electrode connected to the generator and of which one free end, formed of a cluster of filaments made of conductive material, extends to the right of the exhaust pipe to release ions there by corona discharge. The device further includes a diffuser provided with a pipe which, in the extension of the exhaust pipe, delimits a compression chamber, with an expander which extends the pipe and includes a series of channels which extend form an inner face of the expander to an opposite outer face.

A personal protective field generator utilizes at least one pulse generator to generate one or more carrier signals, which are then modulated by a signal modulator unit and output through a field transmission unit in order to create a personal protective field around a user or other object through the skin effect, a byproduct of high frequency pulses at specific voltages. The personal protective field created through the skin effect can repel unwanted contact with the user such as insects, dust, chemical vapors or other environmental hazards.

Disclosed is an insect repulsion and/or barrier system (10) and a method for repelling insects (2) and/or for preventing insects (2) from passing through a defined opening (12) or surface (9). The barrier system (10) is equipped with devices (16) for preventing insects from passing through an opening (12) or for repelling insects when approaching the opening (12) and/or the devices (16). The devices (16) have at least two electrodes (18), whereby different electrical potentials are applied to or can be applied to the at least two electrodes (18). The at least two electrodes (18) are arranged within or on the edge of or outside the opening such that an electrical field (28) is formed between the at least two electrodes (18). The electrical field (28) rejects and/or repels insects approaching the electrical field (28) or prevents insects approaching the electrical field (28) from passing through the opening (12).
