Description

[Detailed description of the invention] [Field of industrial application] The present invention is an electric mosquito repellent in which an electric cord is wound up and fixed at any position when the cord is extended only to the required length during use. It is related to.

[Prior art and its problems]

In the so-called electric mosquito repellent, which uses an electric heating element to heat and volatilize pine with a predetermined length and shape and impregnated with an insecticide, etc., it is used to supply electricity to the electric heating element. Electrical cord is connected. However, this cord is usually 1.5m to 2.0m
It has a length of about m, and when used, this long cord is used by running it along the floor. Therefore, electric mosquito traps are not equipped with a device to wind up the cord, so even when used near an outlet, the entire length of the cord is constantly unrolled, creating a danger for the operator to trip over it. Also, long cords are unsightly.

In view of this, the electric cord can be wound around the electric mosquito repellent, and the cord can be let out only to the required length depending on the usage situation, etc., and the cord can be locked at any position to prevent it from being let out accidentally. There is a device shown in Japanese Utility Model Application Publication No. 55-180533, but this requires the holding piece to be operated against a spring each time the cord is wound in and unwinded, and the base and main body are In addition, it requires parts such as a holder and a spring, and has drawbacks such as difficulty in operability and assembly, and damage to the cord sheathing caused by the holder.

[Means for solving problems]

In order to eliminate this drawback, the present invention forms a cord winding groove between the bottom plate of the main body and the base to allow the cord to be wound around the base, and allows rotation between the main body and the base, and a special mechanism is installed in this groove. This is an electric mosquito repellent that is designed to hold the cord at any desired feeding position without damaging the cord.A pine impregnated with an insecticide is placed on the top of the electric mosquito repellent to gradually volatilize the insecticidal ingredient. The main body has a mat mounting part formed on the upper part of the main body peripheral wall, and a bottom plate is integrally provided on the lower surface of the flat chevron-shaped main body peripheral wall which is equipped with an electric heating element inside, and the bottom plate of this main body. A cord winding groove is formed between the bottom plate of the main body and the base for winding the cord,
A cord locking protrusion is provided on the bottom surface of this bottom plate to lock the cord in any position, and the top surface of the base has a flat V-shape that allows the cord to freely enter and exit the cord winding groove when the above protrusions face each other. Forms a concave surface.

〔Example〕

Next, the present invention will be explained based on embodiments shown in the drawings.

In the figure, 1 is the main body of the electric mosquito repellent in the shape of a flat mountain, and on the upper part of the peripheral wall of this main body, mats of the required size and size impregnated with insecticide etc. are placed in a removable manner. An electric heating element 3 for heating the mat is provided in the main body below the mat device, and a bottom plate 4 is integrally provided on the lower surface of the peripheral wall of the main body. A cord winding groove 10 is provided between the base 6 and the lower surface of the bottom plate provided on the lower surface of the main body, which is necessary for winding an electric cord 11 having a plug at the tip. form the bottom plate 4
One or more cord locking protrusions 5 are provided on the outer periphery of the lower surface of the cord. The height of this cord locking protrusion 5 is such that with normal tension, the cord will not be drawn out beyond the cord winding groove, but if the tension exceeds a certain level, that is, if it is pulled strongly, the cord will be easily drawn out of the groove or strongly. By winding the cord, the cord can be inserted into the winding groove. In this case, the base 6 is rotatable relative to the main body 1.

Furthermore, it makes the cord unwinding and winding smooth,
In order to securely lock the cord, a flat V-shaped recessed surface 9 is formed on the other surface on which the cord locking protrusion is provided, for example, the top surface of the base, and the deepest position of this recessed surface 9 is When the above protrusions face each other, the cord can freely pass between the recessed surface and the top surface of the cord locking projection, but when the cord locking projection is shifted from the recessed surface and is located on a flat surface, the cord will not pass through. The depth and length of the recessed surface are determined so that it is locked and cannot be extended any further.

A drum 7 for winding and collecting the cord is integrally provided at the center of the base provided at the bottom of the main body.

When the base is provided with a recessed surface and rotates in the circumferential direction relative to the main body, this rotation angle is
Although it may be rotated freely 360 degrees, as shown in Figure 3A, the cord locking protrusion on the main body side and the flat surface on the base side are facing each other (this is the cord locking position). ), the cord locking protrusion and the recess may be provided so as to freely rotate within a preset angular range to a position where they face each other to the extent that the cord can be freely inserted into the groove. be.

Note that when winding the cord, the cord is wound around the outer periphery of the drum. At this time, the cord locking protrusion 5 is placed in a position facing the recessed surface 9 as shown in FIG. 3C. In this way, the cord can be easily wound up, and the cord can be easily secured by positioning the cord securing protrusion slightly outside the recessed surface at the position of the arbitrary length of the unwound cord.

[Effect of idea]

According to the present invention, the main body and the base are rotatably provided integrally, and a groove is formed on the outer periphery for storing the cord. Since each has a letter-shaped recess, the cord can be clamped and released by rotating either the main body or the base, and the cord can be held with a simple structure without using any other parts. , the cord is prevented from being extended more than necessary, the cord can be freely adjusted and stopped at the desired position, and since the main body and base are separated, it is possible to prevent chemicals leaking from the mat. This has advantages such as preventing the cord from getting dirty or being damaged by heat from the electric heating element.

[Brief explanation of the drawing]

Figure 1 is a plan view, Figure 2 is a sectional view, and Figure 3 is an explanatory diagram. A shows the case where there is no recessed surface and the cord is locked only with the cord locking protrusion, and B shows the main body. C is a case in which the main body and the base are fixed and the protrusion and the recessed surface are provided facing each other, when the main body and the base are rotated and the cord is wound, unwound and locked using the protrusion and the recessed surface. This shows the case where 1 is the main body, 2 is the mat mounting part, 3 is the electric heating element, 4 is the bottom of the main body, 5 is the cord locking protrusion, 6
is the base, 7 is the drum, 8 is the stop, 9 is the recessed surface,
10 is a cord winding groove, and 11 is an electric cord.
