Abstract

The utility model relates to a PTC heating device. The PTC heating device comprises a PTC ceramic plate, wherein the outer sides of the PTC ceramic plate are coated by copper pipes, insulating yellow paper and aluminum pipes. The PTC heating device has the beneficial effects that: all electrified bodies of the PTC heating device are isolated from the outside world, the external of the whole product is not electrified; meanwhile, since all the electrified bodies are sealed in the aluminum pipes and cannot be contact with water, the PTC heating device also has the waterproof effect, and causes no harm to the user.

Description

A kind of PTC electro-heat equipment

Technical field

The utility model relates to a kind of electro-heat equipment, relates in particular to the anti-electric PTC electro-heat equipment of a kind of waterproof.

Background technology

As Fig. 1, shown in 2, conventional Integral ceiling or super bath PTC heater are PTC potsherd 3, when energising work, aluminium pole piece 4 electrode slices such as grade that are coated on PTC potsherd 3 outsides are all electrified bodies in energising situation, aluminium corrugated plate 1 and power line lead-in wire 5 be also exposed outside, also be easy to charged, this gives consumer in the process of using, bring great hidden danger, although there are various safeguard procedures, but because Integral ceiling or super bath are to be mostly used in bathroom, the contact steam thereby this just cannot keep away from moisture, sometimes even can be sprayed water, this has just increased potential safety hazard greatly, likely user is produced to harm.

Utility model content

The technical problems to be solved in the utility model is, for the above-mentioned defect of prior art, provides a kind of PTC electro-heat equipment.

The utility model solves the technical scheme that its technical problem adopts: a kind of PTC electro-heat equipment, comprise PTC potsherd, and in described PTC potsherd outside, by copper pipe, the yellow paper that insulate, aluminum pipe, be coated successively.

The upper right side of described copper pipe is connected with the second lead-in wire with the first lead-in wire respectively with bottom righthand side, the upper right side of described copper pipe is fixedly connected with by the first silica gel sleeve pipe with the interface of described the first lead-in wire, described copper pipe bottom righthand side is fixedly connected with by the second silica gel sleeve pipe with the interface of described the second lead-in wire, insulation sealing plug shutoff for the left end of described aluminum pipe and copper pipe.

In the both sides, front and back of described PTC potsherd, be provided with the aluminium ripple bar for dispelling the heat.

Described the first lead-in wire and the second lead-in wire outside are insulated yellow paper bag and cover.

The beneficial effect that the utility model reaches is: all electrified bodies of this PTC electro-heat equipment are hedged off from the outer world completely, its whole product outside is not charged, simultaneously, because all electrified bodies are all sealed in aluminum pipe, cannot contact with water, also play the effect of waterproof, so just can not produce harm to user.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:

Fig. 1 is the structure chart of existing PTC electro-heat equipment;

Fig. 2 is the sectional structure chart of existing PTC electro-heat equipment;

Fig. 3 is the structure chart of the preferred embodiment of a kind of PTC electro-heat equipment of the utility model;

Fig. 4 is the sectional structure chart of the preferred embodiment of a kind of PTC electro-heat equipment of the utility model.

Embodiment

As shown in Figure 3,4, a kind of PTC electro-heat equipment, comprises PTC potsherd 4, in PTC potsherd 4 outsides, is coated successively by copper pipe 7, the yellow paper 5 that insulate, aluminum pipe 2.

The upper right side of copper pipe 7 is connected with the second lead-in wire 9 with the first lead-in wire 8 respectively with bottom righthand side, the upper right side of copper pipe 7 is fixedly connected with by the first silica gel sleeve pipe 10 with the interface of the first lead-in wire 8, copper pipe 7 bottom righthand sides are fixedly connected with by the second silica gel sleeve pipe 11 with the interface of the second lead-in wire 9, insulation sealing plug 1 shutoff for the left end of aluminum pipe 2 and copper pipe 7.

In the both sides, front and back of PTC potsherd 4, be provided with the aluminium ripple bar 3 for dispelling the heat.Aluminium ripple bar 3, for heat radiation, guarantees that PTC electro-heat equipment is unlikely to overheated and is burned.

It is coated that first lead-in wire the 8 and second lead-in wire 9 outsides are insulated yellow paper 5.

As shown in Figure 3,4, the utility model PTC(semistor) all electrified bodies of electro-heat equipment comprise PTC potsherd, copper strips etc. all use the yellow paper of insulation (polyamide film) to encase, and be sealed in aluminum pipe, all electrified bodies are hedged off from the outer world completely, make its whole product outside not charged, the first lead-in wire and second lead-in wire of the tape insulation of only drawing are charged., because all electrified bodies are all sealed in aluminum pipe, cannot contact with water meanwhile, also play the effect of waterproof, so just can not produce harm to user.

By reference to the accompanying drawings embodiment of the present utility model is described above; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; rather than restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not departing from the scope situation that the utility model aim and claim protect, also can make a lot of forms, within these all belong to protection of the present utility model.
