Abstract
The invention discloses a liquid heater which comprises a shell body. A closed holding cavity is formed in the shell body. A heating device is arranged in the holding cavity. An air cavity is arranged between the heating device and the inner wall of the shell body. An exhaust vent is formed in the shell body, and the air cavity communicates with outside through the exhaust vent. A unidirectional air vent valve is arranged in the exhaust vent. By arranging the unidirectional air vent valve on the shell body of the heater, when the pressure of the air in the air cavity is excessively high due to heating, high pressure air can be exhausted through the unidirectional air vent valve, so that the pressure in the air cavity is reduced, the damage of the heating device or shell body expansion fracture is avoided, and the heater is safer and more reliable.

Specific embodiment
With reference to Fig. 1～Fig. 4, the present invention is a kind of liquid heater, including a housing, with the accommodating of a closing in housing
Chamber 12, is provided with accommodating cavity 12 between the inwall of heater, heater and housing and has an air chamber, on housing
The steam vent that air chamber can be connected with the external world is provided with, one-way vent valve 131 on steam vent, is provided with.By in heater
On housing arrange one-way vent valve 131, when the gas in air chamber because be heated and pressure it is excessive when, one-way vent valve can be passed through
131 discharge gases at high pressure, reduce the pressure in air chamber, can avoid the situation that heater damage or housing spalling occur,
Make 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 in housing
Electricity or the accident such as short circuit, after the air pressure inside the air chamber increases to certain value, duckbill outlet can be opened under pressure,
Discharge gases at high pressure, reduce the pressure in air chamber, and duck mouth valve structure is simple, it is easy to process.Certainly, in practical application
In, one-way vent valve 131 can also select the other structures such as valve cock or nun buoy.
The heater circuit plate that heater is included PTC heating plates 21 and is adapted with PTC heating plates 21, PTC heating plates 21
Heating power of the quantity according to needed for heater determining.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 is connected with external power source is provided with plate, is provided with housing and 22 phase of power line
The through wires hole 132 of adaptation, power line 22 pass through through wires hole 132 and extend to outside housing, are connected with external power source.PTC heating plates
It is widely used in the art, its structure and principle are known for those skilled in the art, and here is not separately described further.
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
Surround 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.Through wires hole 132 is also disposed at sealing
On part 13, the internal diameter of through wires hole 132 is slightly less than the external diameter of power line 22,22 swelling of power line in through wires hole 132, power line 22
Outer wall be close to the inwall of through wires hole 132, can so make that there is between through wires hole 132 and power line 22 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 on seal 13, is provided with, Plug Division is inserted
Be connected in spliced eye and seal 13 is fixed on main casing 11, on Plug Division, be provided with projection 133, be provided with spliced eye with
The groove that projection 133 is adapted, projection 133 are arranged in groove and are slided with limiting 13 relative main casing 11 of seal, it is to avoid close
Sealing 13 is slipped.Groove can certainly be set on Plug Division.Additionally, in the present embodiment, being dimensioned slightly smaller than for spliced eye is slotting
The size of socket part, Plug Division swelling can make the better tightness between seal 13 and main casing 11 in spliced eye, so.This reality
Apply in example, using a part of inner chamber of 11 sidepiece of main casing as spliced eye, using 13 sidepiece of seal a part as
Plug Division, certainly, in practical application, spliced eye also individually can be opened on the side wall of main casing 11, equally also can be by seal 13
The overall boss etc. that arranges as Plug Division or on seal 13 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, heater is made
Radiating is faster, it is to avoid overheated.In the present embodiment, a plurality of radiating groove 14 is provided with the outer wall of housing, housing had both been increased
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 enable to radiate faster, it is to avoid the gas superheat in air chamber, while conducting strip 3 is also to heater
Play and support and fixed effect.
Above-described embodiment is the preferred version of the present invention, of the invention also to have other embodiments.The technology of this area
Personnel put in the head without prejudice to spirit of the present invention and can also make equivalent variations or replacement, and the modification of these equivalents or replacement are wrapped
It is contained in the scope set by the application claim.
