Specific embodiment
1~Fig. 4 of reference picture, the utility model is a kind of liquid heater, including a housing, has a closing in housing
Accommodating cavity 12, heater is provided with accommodating cavity 12, has an air chamber between heater and the inwall of housing, in shell
Being provided with body can be provided with one-way vent valve 131 by air chamber and the extraneous steam vent for connecting on steam vent.By in heating
On the housing of device set one-way vent valve 131, when the gas in air chamber because be heated and pressure it is excessive when, can be by one-way ventilating
Valve 131 discharges gases at high pressure, reduces the pressure in air chamber, can avoid the feelings that heater damage or housing spalling occur
Condition, makes heater more safe and reliable.
In the present embodiment, one-way vent valve 131 is a duckbill valve, is that normal pressure or pressure are less inside air chamber
In the case of, the duckbill outlet of duckbill valve closes up under elastic reaction itself, it is to avoid extraneous liquid causes leakage into housing
The accident such as electricity or short circuit, after the air pressure inside air chamber increases to certain value, duckbill outlet can be opened under pressure,
Gases at high pressure are discharged, the pressure in air chamber is reduced, and duck mouth valve structure is simple, it is easy to process.Certainly, in practical application
In, one-way vent valve 131 can also be from other structures such as valve cock or nun buoys.
Heater includes PTC heating plates 21 and the heater circuit plate being adapted with PTC heating plates 21, PTC heating plates 21
Heating power of the quantity according to needed for heater determine.By the use of PTC heating plates 21 as heater members, heater control can be made
Warm accurate, thermal conversion rate is high, natural life-span is long, and Billy is more safe and reliable with the heating rod that resistance wire generates heat.Heater circuit
The power line 22 for heater circuit plate to be connected with external power source is provided with plate, is provided with housing and the phase of power line 22
The threading hole 132 of adaptation, power line 22 is through threading hole 132 and extends to outside housing, is connected with external power source.PTC heating plates
It is widely used in the art, its structure and principle are not described further separately herein for those skilled in the art know.
The housing of this heater includes a main casing 11 and the seal 13 being arranged on main casing 11, and accommodating cavity 12 is by main casing 11
Surrounded with seal 13, seal 13 is generally molded by colloidal materials, and duckbill valve equally also can be by identical colloidal materials system
Make, therefore seal 13 and duckbill valve integral molding can be processed more convenient, so can also be on main casing 11
The mounting structure being adapted with the duckbill valve is specially set, the processing capacity of main casing 11 is reduced.Threading hole 132 is also disposed at sealing
On part 13, the internal diameter of threading hole 132 is slightly less than the external diameter of power line 22, the swelling of power line 22 in threading hole 132, power line 22
Outer wall be close to the inwall of threading hole 132, can so make between threading hole 132 and power line 22 have good sealing, can
Environmental liquids are avoided to enter.
Spliced eye is provided with main casing 11, the Plug Division being adapted with spliced eye is provided with seal 13, Plug Division is inserted
Be connected in spliced eye and seal 13 is fixed on main casing 11, projection 133 is provided with Plug Division, be provided with spliced eye with
The groove that projection 133 is adapted, projection 133 is arranged in groove and is slided with respect to main casing 11 with limiting seal 13, it is to avoid sealing
Part 13 is slipped.Groove can certainly be set on Plug Division.Additionally, in the present embodiment, spliced eye is dimensioned slightly smaller than grafting
The size in portion, Plug Division swelling can make the better tightness between seal 13 and main casing 11 in spliced eye, so.This implementation
In example, using a part of inner chamber of the sidepiece of main casing 11 as spliced eye, using a part for the sidepiece of seal 13 as slotting
Socket part, certainly, in practical application, spliced eye also can be individually opened on the side wall of main casing 11, equally also can be by seal 13
The overall boss etc. that set as Plug Division or on seal 13 is used as Plug Division.
In the present embodiment, main casing 11 is a tubular structure, and its front and rear is respectively provided with seal 13 to seal, and makes master
Shell 11 is easy to process.Certainly, the rear portion or front portion of main casing 11 may be designed in the enclosed construction of integral type.
Inner fovea part or male part are provided with the outer wall of housing, to increase the area of dissipation of surface of shell, make heater
Radiating is faster, it is to avoid overheat.In the present embodiment, a plurality of radiating groove 14 is provided with the outer wall of housing, both increases housing
The area of dissipation on surface, also makes heater more attractive in appearance.
Conducting strip 3 is additionally provided with accommodating cavity 12, the inwall of housing is close in one end of conducting strip 3, and the other end is close to add
Thermal, when heater adstante febre, heat can quickly be delivered to housing by conducting strip 3, then be transmitted by housing
To the external world, heater is set to radiate faster, it is to avoid the gas superheat in air chamber, while conducting strip 3 is also to heater
Play support and fixed effect.
Above-described embodiment is preferred scheme of the present utility model, and the utility model can also have other embodiments.Ability
The technical staff in domain can also make equivalent variations or replacement being put without prejudice to the head of the utility model spirit, these equivalent changes
Type or replacement are all contained in the scope set by the application claim.
