Abstract
The invention discloses an automatic pressure control device capable of preventing explosion of a hot water bottle constantly. The automatic pressure control device disclosed by the invention is characterized in that a pressure reduction cabin is arranged outside a bag body of a common hot water bottle, and the pressure reduction cabin and the bag body are connected through a pressure controller; the pressure controller comprises a tube-shaped shell, a ball baffle cover, and a sealing ball, a piston and a spring which are arranged in the shell; a vent hole and an air inlet are formed at the tail end of the shell and the ball baffle cover, respectively; an air bleeding valve is arranged on the pressure reduction cabin; under a normal state, the sealing ball baffles the air inlet on the ball baffle cover which is connected with the shell under action of the spring, and the pressure controller is in a closed state; when pressure intensity in the hot water bottle body is increased to a rated value due to heating or an external force, the sealing ball is pushed away from the air inlet, air or redundant liquid in the bottle enters the pressure controller from the air inlet, then enters the pressure reduction cabin via the vent hole, and is finally discharged at the air bleeding valve till internal pressure and external pressure are balanced, and the air inlet is sealed again by the sealing ball due to action of the spring. The automatic pressure control device disclosed by the invention has the greatest characteristics of being capable of controlling pressure intensity in the hot water bottle to be within a safe range constantly so as to ensure safety of a user.
Description
Technical field
The present invention relates to technical field of living necessaries of humans, especially a kind of automatic voltage operated device that can prevent the hot-water bag blast.
Background technology
Hot-water bag has become the indispensable the articles for daily use of more humans in heating or physical therapy.Yet, when people use, because hot-water bag is when heating or be subjected to the external force extruding, liquid or gas can increase suddenly the pressure that bag produces in the bag, pressure exceeds the bag ability to bear and will explode in bag, happen occasionally so hot-water bag is scalded the accident of human body, this has caused very serious potential safety hazard just for our vast user.
Summary of the invention
For the wretched insufficiency of thoroughly avoiding above-mentioned hot-water bag to explode easily, a kind of automatic voltage operated device that can prevent the hot-water bag blast constantly of patent disclosure of the present invention, no matter the hot-water bag that uses this patent is in heating process or is subjected under the situation of external force extruding, the intravital pressure of bag can be controlled within the nominal value range constantly automatically, to guarantee user safety.
The technical solution adopted for the present invention to solve the technical problems is: going up at common hot-water bag bag (C) increases the automatic voltage operated device that this kind can prevent the hot-water bag blast constantly, and this device comprises pressure controller (A) and decompression storehouse (B).At first, the decompression storehouse is one air bleeding valve bag shaped structure 7. is housed, and pressure controller comprises that 2. tail end has steam vent tube-like envelope 5., shell 2. the other end be head end connect one have air inlet 1. block lid 6., the shell inboard is installed ball sealer by head end according to the order of sequence to the tail end direction
4. 3. piston reach spring, in addition, steam vent one end of pressure controller be embedded in the decompression storehouse (B) cavity in, and the air inlet end the decompression storehouse outside and embed within the common hot-water bag bag.Simultaneously, block the lid the air inlet medial extremity 8. the aperture less than the ball sealer diameter, and greater than the connection chamber of piston external diameter 9. back piston is installed has near the position on the corresponding outer casing inner wall of ball sealer one end, can connect chamber and the anastomosing exhaust passage of steam vent 10. and have with the housing contacts place on the piston side.In use, the hot-water bag internal liquid is owing to adding thermal expansion or because produce gas the bag internal pressure being increased gradually, when pressure in the bag increases to by spring controlled certain specified safety value, internal gas or a small amount of unnecessary liquid advance certain distance along pressure controller to decompression storehouse direction with piston by air inlet, at this moment, normality is the inboard sealing surface of shell air inlet that closed air inlet place overlaps
And ball sealer
The surface is forced to leave, and forms by air inlet, connects chamber, exhaust passage, steam vent and decompression storehouse complete channels, and this moment, gas and a small amount of unnecessary liquid can be discharged in the decompression storehouse in bag, excluded by air bleeding valve.After aerofluxus finished, when pressure was reduced in the safety value in the bag, spring can back into original position with ball sealer by piston, and air inlet is sealed once more, and liquid no longer outflows in the bag at this moment.In addition, when hot-water bag was subjected to the extruding of external force, this automatic explosion-proof device can be controlled at the bag internal pressure within the safety range equally, just in case there is small amount of liquid to be extruded in bag, can only flows in the decompression storehouse along pressure controller, and can not scald human body.
The invention has the beneficial effects as follows that no matter use hot-water bag of the present invention is during when heating or in the extruding that is subjected to external force, the pressure of bag inside all can automatically be controlled within the safety range and can not explode, and user can complete relieved use.Its maximum characteristics are to protect the safety of user constantly.
