RU2013954C1 - Injurious insect killing device - Google Patents

Abstract

FIELD: sanitary and domestic equipment. SUBSTANCE: device has hood, radiation source disposed below hood and screen positioned around radiation source and coated with insect attractive substance. Opposite pole electrodes connected with power frequency source are located below radiation source in one plane coaxially one with respect to the other. Insects attracted by light and bait, for example ferromone, fly over electrodes and reduce resistance between them. As a result, break-down of electrode spacing occurs, which kills insects. EFFECT: increased efficiency and simplified construction. 4 cl, 6 dwg

Description

 The invention relates to sanitation and household appliances / in particular to means for catching and exterminating insects / and in particular can be used as a device using electrical means to protect a person from insect bites.

 There are various devices for protecting against insects / for example / plastic or molded mesh / on each longitudinal edge of which conductors are pressed. A row of perpendicular contact conductors / forming transverse partitions in the mesh openings departs from each of the longitudinal conductors. The longitudinal and the transverse contact conductors of the left side extending from it do not touch the right conductor and the transverse contacts extending from it. The distance between the left and right transverse conductors is such that the insect / getting on the grid closes the circuit between them / and the electric current is supplied to the grid from a conventional network. (US Pat. N 3077050 / class. 43-112 / 1961). This device is not effective enough due to the lack of a light source and is dangerous / because it does not have a barrier against accidental penetration of electrical conductors.

 There is also a device for killing flying insects / containing a light source / lampshade / trap with a valve / rod / on the top of which a fan is mounted with an electric motor for sucking insects with air flow into the trap / base / pipe / screw for moving the trap to the upper and lower positions in order to open and close the holes of the trap / support ring for attaching the lampshade / conical damper-valve. The disadvantage of such a device is its low efficiency / since suction of insects does not guarantee their complete destruction / complexity and cost of design due to the presence of a fan with an electric motor.

 The aim of the invention is to increase the efficiency of the device / expanding its functionality while reducing the size and cost / as well as creating a device that is safe to use and environmentally friendly due to the lack of use of insecticides.

 This goal is ensured by the fact that in the device for the destruction of harmful insects / containing a lampshade / mounted on a hollow rod / inside of which conductors are placed / connected at one end to a voltage source / and the other to a light source lamp cartridge / located inside the lampshade / while the rod is mounted on the base / equipped with switches / introduced bipolar electrodes / made in the form of alternating concentric circles / mounted under the cap around the rod below the light source / but above and the insulating grating and located in the plane / perpendicular to the axis of the rod / while two of the conductors located inside it are connected at one end through the corresponding rectifiers and a switch to the corresponding phases of the mains voltage source / and the other end are also respectively connected to bipolar electrodes / moreover, the lampshade is mushroom-shaped / and the base is equipped with a tray mounted on it / made in the form of a detachable bowl of 2 parts / fastened with 2 clamps. The device is also equipped with a removable mesh additional cap / covering the lamp with a gap and mounted on the cartridge. The base contains a cavity for the possibility of placing an autonomous power source in it. The mushroom cap is equipped with a hook for hanging.

 Figure 1 shows the device / general view; figure 2 is a device in section; in FIG. 3 - arrangement of concentric electrodes (top view); figure 4 - protective insulating lattice; figure 5 - the relative position of the electrodes in the context and their fastening; figure 6 - detachable bowl of 2 parts (top view).

 Figure 1/2 shows a mushroom-shaped lampshade 1 / rod 2 / light source (lamp) 3 / lampholder 4 / mesh 5 / electrodes 6/7 / lead wires 8/9/10 / insulating grating 11 / pan-tray 12 / recesses 13 / base 14 / rectifiers 15/16 / plug 17 / battery compartment 18 / lighting switch 19 / switch for insect killing mode 20 / hook 27.

 Figures 3 and 5 show the relative positions of the concentric bipolar alternating electrodes 6 and 7 / and their fastening with each other by 8 bars (4 upper / pos. 21 and 4 lower / pos.22) and to the rod 2 / e.g. using the latch.

 Figure 6 presents a detachable bowl pan 12 / consisting of 2 parts 23 and 24 / fastened together by clamps 25 and 26.

 The device operates as follows.

 Attracted by the bright light of a light source and the smell of a scented liquid / deposited on a grid / mounted around a lamp / insects fly through a grid of electrically insulating material with cells / whose dimensions are commensurate with the size of insects (sufficient for insects to penetrate) / but preventing accidental penetration of humans / and striving to light source / fall into the holes between alternating electrodes of different polarities / having dimensions / commensurate with the size of insects (e.g. 2-4 mm) / close the circuit / get from the gift of electric shock and fall into the trap in the form of a pan-tray / mounted on the base / from where removed if necessary. The sides of the bowl have several recesses around the circumference / which allows you to use it as an ashtray.

 In general, this device can be used as a lighting table lamp / and the presence of 2 decoupled electrical circuits in it / each of which has its own switch / mounted on the base of the lamp allows the device to be used in 2 modes / or only for lighting / or at the same time to kill insects.

 To be able to use the device in the absence of a power supply network, it has a compartment for accommodating electric batteries.

 For ease of use, a hook for suspension is provided; located at the top of the mushroom cap. To improve aesthetics / for example, when using it in a children's room, it is possible to color the lampshade under a mushroom-mushroom.

 Compared with the prototype device / which is intended only for catching / and not killing insects / the present invention provides effective insect killing and the necessary safety for use with low weight and ease of manufacture and operation / as well as expanding its functionality / since the device-device can be used also as a beautiful lamp / both in stationary conditions / where it can be installed on the table surface and included in the network / and in traveling conditions / where there is no a source of mains voltage.
