Reference numeral:
1. aluminium die casting body 1.1. temperature controller mounting groove 2. temperature controller 2.1. binding posts
3. silica gel glass fibre sleeve 4. insulating papers 5. positioning seats 6. wire sockets
7. draw lead 8. leads
Below in conjunction with the drawings and specific embodiments the technical solution of the utility model is elaborated.
The specific embodiment
Heater comprises mushroom capitiform aluminium die casting body 1, dress spiral electrothermal tube (not shown in the accompanying drawing) in it, and its two ends are connected with lead 8, and temperature control tank 1.1 and FUSE (fuse) mounting groove are set in aluminium die casting body 1.Shown in Fig. 2-3, overtemperature protection system comprises temperature controller 2, silica gel glass fibre sleeve 3, insulating paper 4, positioning seat 5 and wire socket 6.
The operation principle of temperature controller is: in heater immerses the water receptacle of humidifier during operate as normal, temperature controller is installed temperature maintenance in the vallecular cavity about 120 ℃.When anhydrous dry combustion method in the humidifier water receptacle or be evaporated to heater surface when anhydrous; the temperature of heater can very fast rising; the temperature controller that is located in the temperature controller mounting groove passes through its metal shell temperature-sensitive; when temperature reaches the design temperature (about 130 ℃) of temperature controller, turn on thrermostatic bimetal-plate is quick, separate with electric contact; disconnect the heater circuit; make heater stop heating, the maximum temperature of heater can reach about 250 ℃, thereby reaches the effect of limit temperature, protection.The PTC sheet in parallel heating this moment with the temperature controller contact, the PTC sheet has the stable characteristics of heating temp, and it can make the temperature controller connection so that thrermostatic bimetal-plate can not automatically reset of keeping higher temperature.When the people is cut off the electricity supply (pulling up plug), after the temperature controller cooling, thrermostatic bimetal-plate restPoses, and makes the temperature controller connection that resets.
Because the outer casing electrification of the temperature controller of selecting for use 2, therefore the silica gel glass fibre sleeve 3 with both ends open is contained in temperature controller 2 outsides as insulation sleeve, insert then in the temperature controller mounting groove 1.1, one end supports to bottom land, this temperature controller mounting groove 1.1 is a tubular channel hole, by the spiral electrothermal tube in mushroom capitiform aluminium die casting body 1.The bottom that silica gel glass fibre sleeve 3 opens wide makes temperature controller 2 temperature-sensitives rapid, makes thrermostatic bimetal-plate action in time to stop heating, and after it stopped heating, the surface temperature of heater also can be dashed to 250～280 ℃.
Insulating paper 4 is designed to the bottom and stretches out the metal shell certain-length, make temperature controller 2 in silica gel glass fibre sleeve 3 prop up the bottom land of temperature controller mounting groove 1.1 with insulating paper 4, the length that insulating paper 4 stretches out requires to be as the criterion to reach creep age distance, and (creep age distance is an electrical apparatus insulation requirement term, for guaranteeing the mutually insulated of two electrical bodies, various countries and regional standard require its minimum range of leaving mutually), according to European standard, require greater than 4mm herein.U.S. UL standard can be less, need meet the proof voltage requirement.Insulating paper adopts " NOMEX of Du Pont " paper, is a kind of heatproof high dielectric strength and insulating materials with certain degree of hardness, can be crooked when it props up the bottom land of temperature controller mounting groove 1.1, thus guarantee creep age distance.
On the top of temperature controller 2 positioning seat 5 is set, positioning seat 5 is made by pottery or plastic material, its bottom props up the temperature controller shell, positioning seat 5 is provided with the export of two electrical leads, the end cap of positioning seat 5 covers the top of silica gel glass fibre sleeve 3, positioning seat 5 supports with the humidifier installing rack when heater assembles, and silica gel glass fibre sleeve 3 and temperature controller 2 are played the role of positioning, and prevents temperature controller 2 displacements or deviates from.
