Description

A kind of novel air heater

Technical field:

The utility model relates to the air heating apparatus technical field, refers in particular to a kind of novel air heater.

Background technology:

In equipment such as massage type (SPA) bathtub, bubble pin machine, need constantly be blown into air from its bottom and produce bubble to reach massage effect.Common the said equipment, usually only has the air blowing function, when constantly in water, blowing, air will be taken away the heat of water, water temperature is constantly reduced, therefore need constantly to replenish new hot water, so both increased the trouble of operation, make troubles to the user, more cause the significant wastage of water resource.The principle of designer according to hair drier arranged again, utilize the form of resistance wire heating to design massage type (SPA) bathtub, the bubble pin machine that in blowing, heats, though can reach the effect of keeping water temperature and massage, but its structure is installed complicated, be unfavorable for safeguarding, and the more important thing is the IR wavelength that produces owing to the resistance wire heating not in the comfortable scope of human body sensory, so service time, length made us doing not feel like oneself on the contrary, therefore had much room for improvement.

The utility model content:

The purpose of this utility model is to overcome the above-mentioned weak point of prior art, provide a kind of novel, can be used for the air heating apparatus in blowing apparatus or the ventilation shaft.

The utility model realizes that the technical scheme that its purpose adopts is: the novel air heater, described heater comprises insulation crust, be installed in heater in the described insulation crust, be installed in the described insulation crust and with described heater the two poles of the earth electrodes in contact contact and the lead that is connected with described electrode contact blade respectively respectively, described heater comprises the diatomite matrix in the middle of being positioned at, the silver electrode that is attached to the Electric radiant Heating Film of described diatomite matrix surface and is attached to diatomite matrix two ends, and described heater offers some air vents.

Periphery in described heater forms lug boss.

Described insulation crust is made up of the first removable shell and second shell, and the end of wherein said first shell offers first ventilating opening and forms first position-limit mechanism; The end of described second shell offers second ventilating opening and forms second position-limit mechanism.

Described first, second position-limit mechanism can be structures such as inward flange or interior salient point or cross.

Described electrode contact blade ringwise.

Between described lead and electrode contact blade, be connected with thermal switch.

After the utility model adopts said structure, the air heating apparatus overall package is convenient, install and use also very convenient, satisfy add the hot-air needs in, the far infrared that diatomite matrix heating power produces, wavelength and can play the blood circulation that promotes and improve the user, strengthens metabolism, improves effects such as body immunity in the comfortable scope of human body sensory, brings healthy and comfortable to the user.

Description of drawings:

Fig. 1 is the stereogram of the utility model embodiment;

Fig. 2, Fig. 3 are the decomposition texture schematic diagrames of the utility model embodiment different angles;

Fig. 4 is the cross-sectional view of the utility model heater.

The specific embodiment:

Below in conjunction with specific embodiments and the drawings the utility model is further specified.

As shown in Figure 1, 2, the described air heating apparatus of present embodiment comprises insulation crust 1, heater 2, electrode contact blade 3 and lead 4, and wherein, the two ends of heater 2 contact and be fixed on the inside of insulation crust 1 respectively with electrode contact blade 3.

Particularly, shown in Fig. 2,3, the insulation crust 1 whole cylindrical body of present embodiment comprises first shell 11 and second shell 12, and the two is removable connection combination, adopts known technology to realize; The end of this first shell 11 offers first ventilating opening 110 and forms first position-limit mechanism 111; The end of this second shell 12 offers second ventilating opening 120 and forms second position-limit mechanism 121; Described first position-limit mechanism 111 of present embodiment, second position-limit mechanism 121 are the inward flange that is molded over outer casing inner wall, its effect is to be used for mounting circular ring shape electrode contact blade 3 and columniform heater 2, obviously, first, second position-limit mechanism 111,121 also can be the interior salient point more than three or three or the structure of one " ten " cabinet frame shape, or other similar structures; All the internal diameter with insulation crust 1 is suitable for the external diameter of the electrode contact blade 3 of described annular and the maximum outside diameter of heater 2, therefore can described electrode contact blade 3, heater 2 be fixed on formation one integral body in the insulation crust 1 by first shell 11 and second shell 12 at two ends.

In conjunction with Fig. 2, Fig. 3, shown in Figure 4, heater 2 described in the utility model is made up of diatomite matrix in the middle of being positioned at 21 and the silver electrode 23 that is attached to the Electric radiant Heating Film 22 on described diatomite matrix 21 surfaces and is attached to diatomite matrix 21 two ends, described heater 2 offers some air vents 20, and form several lug bosses 24 in the periphery of heater 2, between heater periphery and insulation crust, to form the gap for circulation of air, make the heater 2 and the heat exchange area of air reach maximum, increase efficiency of utilization.Certainly, diatomite heater 2 described in the utility model also can be designed to other shapes, for example cellular, coal briquette shape or the like; The diatomite heater that the utility model adopts is to be earlier that material is made the matrix 21 that forms some air vents 20 with diatomite, form Electric radiant Heating Film 22 in matrix 21 surfaces by high temperature sintering again, coated silver is starched at the two ends of matrix 21 then, after high temperature reduction is handled, promptly form silver electrode 23, and then make described heater 2 at the diatomite layer two ends.Because the Electric radiant Heating Film 22 on diatomite surface adopts semi-conducting material manufacturing, the far infrared wavelength that produces behind its heating power is in the comfortable scope of human body sensory, therefore can bring comfortable sensation to the user, add the physiotherapy function of far-infrared radiation, long-term use can bring health to the user.

In addition, for strengthening practicality of the present utility model, be connected with thermal switch 5 between a lead 4 and the electrode contact blade 3 therein, the temperature of these thermal switch 5 induction air, and can judge whether that continuation energising heating or disconnection stop heating, play the effect of automatic adjusting air heat temperature according to the temperature of setting.

In sum, the utility model is simple in structure, and is easy to use, is highly suitable in the equipment such as massage type (SPA) bathtub, bubble pin machine to use.
