Abstract
The utility model relates to a pressure-limiting explosion proofing device, belonging to the field of household appliances. The pressure-limiting explosion proofing device consists of a bag body, a heating core arranged in the bag body, a socket fixed on the bag body and a sealing base, wherein the sealing base is thermally sealed with the bag body together and is provided with a pressure-limiting explosion proofing device; the limit-pressure explosion proofing device of the sealing base comprises a bracket arranged inside the sealing base, a mandril arranged between the bottom of the sealing base and the bracket, a spring arranged on the mandril and a pressure-limiting switch arranged on the bracket. According to the pressure-limiting explosion proofing device disclosed by the utility model, a power supply can be automatically switched off when the pressure in a hot-water bag exceeds the safety value, explosion is effectively suppressed, and the user safety is ensured.
Description
Technical field
This utility model relates to a kind of limiting anti-explosion unit for pressure, belongs to household appliance technical field.
Background technology
The temperature control of the warm handbag of electricity of the prior art is accomplished by temperature controller; Promptly when reaching temperature, circuit is cut off in the temperature controller action, and this type temperature controller adopts thrermostatic bimetal-plate as temperature-sensing element; Utilize butterfly shaped dual metal sheet under temperature action, to produce the moment dancing principle of suddenling change; Through the effect of mechanism, contact is moved rapidly, reach the purpose that is switched on or switched off circuit.This is used temperature controller to control temperature, and nothing is rushed down pressure and pressure limiting device is controlled the electric handbag bag internal pressure that warms up, in case temperature controller lost efficacy, a bag internal pressure is crossed conference and caused that the electric handbag that warms up explodes, and causes the accident.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of prior art and a kind of limiting anti-explosion unit for pressure of designing.
This utility model by bag, be arranged on the intravital heat generating core of bag, be fixed on socket on the bag, form with the bag heat seal seal receptacle that has limiting anti-explosion unit for pressure together, described limiting anti-explosion unit for pressure comprises and is arranged on the inner support of seal receptacle, is arranged on bottom the seal receptacle and the push rod between the support, is installed in spring and rack-mount pressure limiting switch on the push rod.
Seal receptacle is processed with PVC.With lead the electrode on the socket, heat generating core, pressure limiting switch are linked to be electric loop.When making the bag internal pressure, the energising heating increases; The deliquescing of being heated of seal receptacle bottom is inwardly heaved, and after the bag internal pressure reached higher pressure, the height that heave the seal receptacle bottom made the closed pressure limiting switch of push rod; The tripping of pressure limiting switch normally-closed contact; Cutting off the electricity supply stops heating, and restriction pressure rises, and guarantees hot water bag safety.
This utility model can cut off the electricity supply when hot water bag bag internal pressure surpasses safety value automatically, effectively containment blast, thus guarantee user security.
Below in conjunction with accompanying drawing and specific embodiment this utility model is further specified.
Description of drawings
Fig. 1 is the structural representation of this utility model.
Fig. 2 is the side-looking cross-sectional schematic of Fig. 1.
The specific embodiment
Referring to Fig. 1～2; This utility model by bag 7, be arranged on heat generating core 8 in the bag 7, be fixed on socket 6 on the bag 7, form with the bag 7 heat seals seal receptacle that has limiting anti-explosion unit for pressure 3 together, described limiting anti-explosion unit for pressure comprises the support 4 that is arranged on seal receptacle 3 inside, be arranged on push rod 2 between seal receptacle 3 bottoms and the support 4, be installed in the spring 1 on the push rod 2 and be installed in the pressure limiting switch 5 on the support 4.Seal receptacle 3 usefulness PVC process.With lead the electrode on the socket 6, heat generating core 8, pressure limiting switch 5 are linked to be electric loop.When making bag 7 internal pressures, the energising heating increases; The deliquescing of being heated of seal receptacle 3 bottoms is inwardly heaved, and after bag 7 internal pressures reached higher pressure, the height that heave seal receptacle 3 bottoms made push rod 2 closed pressure limiting switches 5; The tripping of pressure limiting switch normally-closed contact; Cutting off the electricity supply stops heating, and restriction pressure rises, and guarantees hot water bag safety.
