Abstract
The utility model relates to an electrical hand-warming bag with a pressure relief function, belonging to the technical field of household appliances, which comprises a closed bag body, a fluid filled in the bag body and an electrical heater. The utility model is characterized in that: the bag body is also provided with a pressure relief device; the pressure relief device comprises an inlet valve body, an outlet valve body, a valve core arranged in the valve body with a thrust spring, a pressure leather cup arranged at the position corresponding to the valve core sealed and connected to the valve body, a thrust plate arranged on the pressure leather cup and two ejector bars arranged vertically in the thrust plate crossing the valve body and extending under the valve core; the outlet of the valve body crosses the bag body, extends outside the bag body and communicates with the atmosphere. The utility model is characterized in that: the set pressure leather cup can exert the function of collecting pressure and providing safety protection under low pressure situations when the pressure is out of control. The utility model can be used to replace existing electrical hand-warming bags.
Description
Technical field
This utility model relates to the warm handbag of electric heating in the household electrical appliance technical field.
Background technology
At present the warm handbag of the electric heating that uses mostly is made of a closed bag, the liquid and the electric heater that are contained in the bag, provides thermal source warming by electric heater with the water heating.The used lining of electric hot-water bag belongs to plastic foil, and the pressure that can bear is limited, in case temperature control, water temperature will constantly rise and cause the pressure rising to cause electric hot-water bag to pop, and the user is damaged poor stability.For addressing this problem, existing method is to adopt a temperature controller to monitor, deenergization when water temperature reaches a setting value.This method does not tackle the problem at its root yet, in case temperature controller or power supply control are broken down, can cause a bag internal pressure to increase equally.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, and a kind of warm handbag of electric heating with pressure release function is provided, and the warm handbag of this electric heating can release a bag internal pressure automatically under the situation that very little pressure raises.
Originally the formation that has the warm handbag of electric heating of pressure release function comprises a closed bag, be contained in liquid and electric heater in the bag, it is characterized in that in described bag, also being provided with a pressure relief device, this pressure relief device is by having into, the valve body of outlet, be installed in the spool that has a thrust spring in the valve body, be sealedly connected on the pressure leather cup of the position relative of valve body with spool, be arranged on the push-plate on the pressure leather cup and be vertically set on the push-plate two and pass the push rod that valve body stretches below spool and constitute, the outlet of described valve body is passed bag and is stretched outside bag and be communicated with atmosphere.Under normal circumstances, under the effect of thrust spring, the pressure that spool is subjected to has been sealed the row pressure passage of valve body, and pressure relief device is in treats duty.In when, abnormal conditions taking place making pressure increase in the bag when, pressure leather cup in the pressure relief device plays the effect of collecting pressure, promptly the slight pressure of Zeng Jiaing has become bigger active force after acting on the larger area pressure leather cup, this active force forces the pressure leather cup to move to the spool direction together with push-plate and push rod, along with the increase of pressure, push rod contacts spool, overcomes the tension force of thrust spring and spool is opened, the inner chamber that is about to bag is communicated with atmosphere, thereby the abnormal pressure that increases is discharged.After pressure obtained discharging, spool was closed, and returns to normal operating conditions.In case pressure raises once more, spool will be opened once more, all the time the pressure in the bag be remained in the safety range far below the breakdown pressure of product.Thereby fundamentally well played the effect of safeguard protection.
Still a baffle plate can be set above the outlet of described valve body, the benefit of doing like this is that the high-temp liquid in the bag is blocked by baffle plate when discharging, and avoids directly ejection to hurt sb.'s feelings.
This utility model plays the effect of collecting pressure by the pressure leather cup is set, and out of control later under pressure increase seldom, the pressure leather cup also can be collected enough pressure and open spool with release pressure, provides safeguard protection under pressure low pressure situation out of control.For providing a kind of reliable in action, safe electric heating, consumer warms up handbag.
Content of the present utility model further illustrates with the following Examples.

The specific embodiment
As shown in Figure 1, the formation that originally has the warm handbag of electric heating of pressure release function comprises a closed bag 13, is contained in liquid 14 and electric heater 15 in the bag, and is all identical with prior art with top.In described bag 13, be provided with a pressure relief device 16, referring to Fig. 2～3, this pressure relief device is by having import 4, outlet 11 valve body 8, be installed in the spool that has a thrust spring 76 in the valve body 8, the pressure leather cup 1 of the position relative with spool 6 that be sealedly connected on valve body 8, be arranged on the push-plate 2 on the pressure leather cup and be vertically set on the push-plate 2 two and pass the push rod 3 that valve body 8 stretches below spool 6 and constituted, and the outlet 11 of described valve body is passed bag 13 and stretched outside bag and be communicated with atmosphere.5 for being fixed in the rubber gasket that plays better airtight effect on the spool 6 among the figure, 10 is the plug screw of installed thrust spring 7, outlet 11 can be seated in the below of the power input stand 17 of electric heater 15, the benefit of doing like this is to utilize power input stand to serve as baffle plate to block the high-temp liquid of discharging in the bag, avoids it directly to spray and hurts sb.'s feelings.Also can above outlet 11, a baffle plate be set separately.At regular intervals between normal conditions lower push rod 3 and the spool 6, in case pressure anomaly rises, pressure leather cup 1 begins upwards to promote push-plate 2 after acquiring a certain degree, push-plate 2 promotes push rod 3 again and moves upward, push rod 3 withstands spool 6 it is upwards lifted, when pressure continues to build up to thrust that the pressure leather cup makes progress and has overcome thrust spring 7 applied pressures, spool 6 is opened, air pressure in the bag forces liquid to enter valve body from import 4, Clearance Flow between spool 6 and valve body 8 again, the outlet 11 from the plug screw 10 is at last flowed out and is realized pressure releases.
Installation during for convenient the use can be socketed with a mount pad 9 in the outside of described valve body 8.Pressure relief device can form the structure that is tightly connected by its mount pad 9 and bag 13 heat seals together.Pressure leather cup 1 and the seal receptacle 9 heat sealable one that together form.
