Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a pet heater for protecting pets such as dogs and cats from cold air during winter. More specifically, the present invention relates to a heater for pets that incorporates a planar heating element that utilizes electrical energy.

[Problems to be solved by conventional technology and ideas] Conventionally, as a pet heater, a cord heater or a sheet heating element pasted to a metal plate was attached to the back of an upper cover made of metal or synthetic resin. A heater body is made by fitting or fixing a bottom plate to the lower opening surface of the upper cover with screws, and a plastic sheet or brushed mat is pasted on the heater body, which is commercially available.

However, in these products, the top cover and bottom plate are fitted or fixed with screws, and they are not waterproof, so if you wash the heater case (case consisting of the top cover and bottom plate) with water to remove dirt, etc. The risk of leaking into the heater case and causing electrical insulation failure was extremely high, and washing with water was impossible. In addition, it is heavy because it uses a metal case or metal plate.
The heater case was hard, and although there was a mat attached to the top, there were some drawbacks such as lack of cushioning.

Furthermore, the cost of the constituent materials for the heater itself increases.
There are problems such as it takes time and effort to manufacture and the product cost is high.

The object of the present invention is to improve the problems of conventional pet heaters, and to provide an inexpensive pet heater that does not allow water to leak into the heater case and has cushioning properties.

[Means for solving the problem] The structure of this invention is shown in Figures 1, 2 and 3.
This will be explained with reference to the figures. FIG. 1 is a plan view of the pet heater of the present invention, FIG. 2 is a bottom view, and FIG. 3 is a sectional view taken along line A-A' of the pet heater shown in FIG.

A reinforcing plate 5 and a heat insulating cushion material 6 are sequentially fixed to the surface of the planar heating element 4, and the heating plate, which has the cushion material 3 fixed to the other surface, is attached to the inner cover 2 made of plastic film and its periphery with a bite prevention rod. 7 is sequentially covered with an outer cover 1 made of cloth.

The planar heating element 4 is preferably one in which carbon-based conductive resin is coated or printed on a base material such as glass cloth or plastic film, and the resulting material is insulated with plastic film or the like. A reinforcing plate 5 is attached to one side of the planar heating element 4, and a cushion material 3 is attached to the other side using, for example, adhesive tape.

The planar heating element 4 may be provided with an over-rise prevention device such as a temperature fuse and an automatic temperature control device such as a thermostat on its lower surface. in this case,
This portion of the reinforcing plate 5 is punched out in order to prevent the reinforcing plate 5 from applying pressure to the overheat prevention device and the automatic temperature control device.

The reinforcing plate 5 is a fiber board, a fiber board,
Plastic boards are used, especially fiber boards made from wood pulp (product name: Hokuetsu Paper Industries)
Pasco Co., Ltd.) is suitable because it is lightweight and has excellent mechanical strength.

As the heat insulating cushion material 6, a sheet of felt, soft plastic foam, etc. is used, and felt is particularly suitable from the viewpoint of performance and cost. The size of the plane should be equal to or larger than the size of the reinforcing plate 5, and the thickness is not particularly limited, but a range of 5 to 20 mm is appropriate.
The heat insulating cushion material 6 is attached to the reinforcing plate 5 using, for example, adhesive tape.

As the cushion material 3, a sheet made of soft plastic foam such as soft polyurethane foam or polyvinyl chloride foam is used. The plane size is the same as that of the heat insulating cushion material 6, and the thickness is not particularly limited, but a range of 5 to 20 mm is appropriate.

The inner cover 2 must be made of a material that can be heat-sealed, and a plastic film such as polyvinyl chloride film or polypropylene film is used, and the heat-generating plate is sandwiched between the films from above and below, and the periphery is heat-sealed. Although there are no particular restrictions on the means for heat fusion, a high frequency welder is preferred.

An outlet for a lead wire 9 connected to the planar heating element 4 is provided on the outer periphery of the inner cover 2 .

The outer cover 1 is made of cloth, and a bite prevention bar 7 made of plastic or metal is covered with the cloth and sewn over the entire periphery. The upper part of the outer cover 1 is preferably quilted with resin cotton or the like built therein to improve cushioning properties. A fastener 8 is attached to the lower part in order to take in and out the heater body (the part where the heating plate is covered with the inner cover). The anti-bite rod 7 made of plastic or metal plays the role of preventing biting of pets and maintaining the shape of the outer cover. The anti-bite rod 7 must be elastic and easily bendable, and a diameter of 2 to 5 mm is suitable.

[Function] In the pet heater configured as above, by supplying electricity to the sheet heating element, the inner cover and outer cover facing the sheet heating element can be stably maintained at an appropriate set temperature (37 to 42 degrees Celsius). It is heated.

[Example] An example of the present invention is shown in FIGS. 1, 2, and 2.

The present invention is not limited to this embodiment.

[Effects of the invention] As described above, according to the invention, the heating plate is sandwiched between the upper and lower sides by plastic films, and the periphery is heat-sealed to seal it, so that if dirt or the like adheres to the heater, the outer cover can be removed and washed. Along with being able to
Furthermore, it is possible to wash the heater body (the part where the heating plate is covered with the inner cover) with water.

In addition, the heater body is lined with cushion material,
A cushioning effect is achieved by using a flexible plastic film for the inner cover, and by covering the heater body with a cloth outer cover with a plastic or metal anti-bite rod attached to the periphery. , and also prevents pet biting.

The constituent materials are lightweight, inexpensive, and easy to manufacture.
It is possible to reduce the weight and cost of the product, and it is easy to handle, so it can be widely used as a pet heater.
