Abstract
An electric thermal bag pressure relieving device comprises an electric thermal bag; a socket and a pressure relieving device are mounted on the wall of the electric thermal bag; and an electrical heating device is connected into the socket. The electric thermal bag pressure relieving device is characterized by comprising a sleeve gasket welded with the electric thermal bag; a valve seat is mounted in the sleeve gasket; a valve cap is arranged at the lower part of the valve seat; the valve cap is in contact with a spring; a valve rod is arranged on the spring; a vent hole is formed at the top of the valve seat; a jacking rod is arranged below the vent hole; and a centre hole is formed in the valve cap. The technical scheme not only can be used for injection, but also can relieve pressure when the air pressure is too high; moreover, the whole pressure relieving device has a simple structure, is easy to manufacture and install, and is convenient to use.
Description
Technical field
This utility model relates to electric warming bag, particularly relates to a kind of electric warming bag that prevents and causes the safety relief device of explosion owing to pressure raises.
Background technology
Electric warming bag also is electric hot-water bag, or claims heat storage type electric heating hand warmer, and the basic structure of product comprises the water storage bag; Water storage bag mounting receptacle and electric heater unit, and liquid injection port is arranged, liquid injection port has stopper; At first transfer to stopper during use, stopper has beyond the Great Wall been annotated behind the water in water filling in bag; Begin energising heating,, pine for to produce certain gas adding because aqueous medium heat storage type hot-water bag is continuous heating (temperature is up to 80 ℃) liquid in confined space; Gas has gathered many bag internal pressure is raise, in case the bag explosion can cause personal injury accidents.Standard GB 4706.99-2009; Clearly regulation is arranged, " flexible hand warmer structurally should have prevent in galvanization, to occur the too high protector of hand warmer internal gas pressure " in the specific (special) requirements to the safe heat storage type electric heating hand warmer of domestic and similar applications electrical equipment.Like utensil over-pressure safety device is not installed, it is defective then to declare this utensil.And existing electric warming bag product is not generally installed the too high protector of air pressure, or exists problems such as the too high protector of air pressure is undesirable.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming that prior art exists, to provide a kind of stopper to existing liquid storing bag liquid injection port to improve design, both be preserved for fluid injection, can playing the release effect again, electric warming bag pressure relief device simple in structure, easy to use.
The technical scheme of this utility model electric warming bag pressure relief device is: comprise electric warming bag, connect electric heater unit in mounting receptacle and the pressure relief device on the electric warming bag wall, socket; It is characterized in that pressure relief device comprises the sealing shroud that welds mutually with electric warming bag, valve seat is installed in the sealing shroud, under the valve seat valve gap is arranged; Contact with spring on the valve gap, valve rod is arranged on the spring, steam vent is arranged at the valve seat top; Push rod is below steam vent, and valve gap is shaped on mesopore.
The utility model discloses a kind of electric warming bag pressure relief device, during installation with spring housing on valve rod, push the valve seat from the bottom, cover valve gap again, with spinning machine valve gap is closed up, it is fixing that valve gap and valve seat are pressed mutually.To electric warming bag energising heating the time,, show that bag internal pressure raises, and needs release if find that electric warming bag obviously expands.Elder generation's deenergization, to be cooled after room temperature, with pole (like little bamboo rod) from the steam vent entering with the push rod pressed downward, and push electric warming bag gently, gas is discharged from steam vent, dry release liquid after, reheat use.In electric warming bag, during fluid injection, extract pressure relief device when needs, fluid injection gets final product in sealing shroud.This technical scheme both can be used for fluid injection, release when too high as air pressure again, and whole pressure relief device is simple in structure, makes, install easily, and easy to use.
This utility model electric warming bag pressure relief device, described socket and pressure relief device are installed on the same one side of electric warming bag front or reverse side.
Description of drawings
Fig. 1 is the structural representation of this utility model electric warming bag pressure relief device;
Fig. 2 is the structural representation that valve gap, valve rod and spring are installed in the valve seat.
The specific embodiment
This utility model relates to a kind of electric warming bag pressure relief device, like Fig. 1-shown in Figure 2, comprises electric warming bag 6, mounting receptacle 7 and pressure relief device on the electric warming bag wall; Connect electric heater unit in the socket, it is characterized in that pressure relief device comprises the sealing shroud 5 that welds mutually with electric warming bag 6, valve seat 1 is installed in the sealing shroud; Valve gap 2 is arranged under the valve seat, contact with spring 4 on the valve gap 2, valve rod 3 is arranged on the spring; Steam vent 11 is arranged at the valve seat top, and push rod 3 is below steam vent 11, and valve gap 2 is shaped on mesopore 21.During installation spring 4 is enclosed within on the valve rod 3, pushes the valve seat 1, cover valve gap 2 again, valve gap 2 is closed up, make valve gap and valve seat 1 press fixing mutually with spinning machine from the bottom.When giving electric warming bag 6 energising heating,, show that bag internal pressure raises, and needs release if find that electric warming bag obviously expands.Elder generation's deenergization, to be cooled after room temperature, get into push rod 3 pressed downward from steam vent 11 with pole (like little bamboo rod), and push electric warming bag 6 gently, make gas from steam vent 11 discharges, dry release liquid after, reheat use.In electric warming bag, during fluid injection, extract pressure relief device when needs, fluid injection gets final product in sealing shroud 5.This technical scheme both can be used for fluid injection, release when too high as air pressure again, and whole pressure relief device is simple in structure, makes, install easily, and easy to use.Described socket 7 is installed on the same one side of electric warming bag 6 fronts or reverse side with pressure relief device.
