Abstract
The invention relates to a steam-proof vacuum pot and a pot lid thereof. The steam-proof vacuum pot comprises a pot body and a pot lid, wherein an water outlet control plug of the pot lid comprise a plug body, a mandrel control unit and a button; a main spring of the mandrel control unit is sleeved at the upper part of a mandrel and is limited between an inner limiting barrel of a core barrel and a spring end cover which is arranged on the upper end of the mandrel; the lower end of the mandrel is provided with a gap and a sealing ring; when the mandrel slips downward along a sealing end cover through the elasticity of the main spring, the sealing ring is separated from the sealing end cover and the steam in the port is communicated with a steam release chamber through the gap, so that a steam release structure is formed; a buffer spring is sleeved outside the barrel body of the core barrel and is arranged between a limiting shoulder outside the barrel body of the core barrel and the upper side of the sealing end cover; the mandrel control unit drives the sealing end cover to move downward through the elasticity of the buffer spring so as to form a water outlet control structure. The steam-proof vacuum pot and the pot lid have the advantages of saving labour in control, safety and scald protection.
Description
Technical field
The present invention relates to a kind of vapor-proof vacuum jug and pot lid thereof.
Background technology
The structure of existing vacuum jug is Fig. 1, shown in Figure 2, and when kettle was packed boiling water into, the kettle internal upper part was full of water vapour; When pushing button, end cover throws open, and the water vapour in the kettle just gushes out quickly; Take sb. aback,, also can scald the people because water vapour discharges fast; Simultaneously, traditional control structure is owing to exist end cover inside and outside differential pressure, end cover can not do to such an extent that require great effort than big and control ratio.
Summary of the invention
The objective of the invention is provides a kind of control laborsaving, safe, anti-scald vapor-proof vacuum jug and pot lid thereof to above-mentioned existing problems.
The present invention, realize that above-mentioned purpose is such: comprise kettle body and pot lid, pot lid comprises the main lid that is connected with the kettle body, and main lid is provided with out water management kettle plug, and the top that goes out water management kettle plug is connected with loam cake; Go out water management kettle plug and comprise cock body, mandrel control assembly and button; The mandrel control assembly comprises mandrel, main spring, buffer spring and end cover; Cock body is provided with the core tube that mandrel is installed, and main spring is set in the top of mandrel and is in the interior position-limiting drum of core tube and is arranged between the spring end cap of mandrel upper end and spacing; End cover is set in the lower end of mandrel; Go along with sb. to guard him into steam between cock body and the end cover and discharge chamber; The lower end of mandrel is provided with breach and sealing ring, and mandrel breaks away from end cover by sealing ring when the lower slider and is communicated with by breach that steam constitutes the steam releasing structure with steam release chamber in the kettle along end cover through the elastic force of main spring; It is outer and be between the upside of outer limited shoulder of the cylindrical shell of core tube and end cover that buffer spring is set in the cylindrical shell of core tube, and the mandrel control assembly constitutes the control water flowing out structure through the moving down of elastic band movable sealing end cap of buffer spring.
The piston that supplies mandrel in the core tube, to slide is equipped with in the present invention, core sleeve, is convenient to mandrel and slides flexible, reliable.
The present invention, the periphery of end cover is provided with the flexible seal ring to the lower limb sealing of cock body, makes sealing effectiveness better.
The present invention, owing to adopt the steam releasing structure of interior steam of breach connection kettle and steam release chamber, after pushing button; End cover can not opened earlier; But mandrel being moved down earlier through main spring, high-temperature water vapor slowly gets into steam release chamber from the small gap of mandrel lower end earlier in the kettle, after 0.8 ~ 1 second; When inner and outer air pressure arrives balance, open the end cover water outlet again by the elastic force effect of buffer spring; More traditional control structure, the present invention, the water outlet then of first released vapour; Accomplish only step control of two steps action, simultaneously, owing to consider the internal and external pressure balance principle; So end cover also can be done greatly and control ratio is more laborsaving, and traditional control structure, owing to there is inside and outside differential pressure; End cover can not be done greatly and control ratio is required great effort, so the present invention also has significant good effect.
The present invention has laborsaving, safe, the anti-scald advantage of control.
Following embodiment combines accompanying drawing that the present invention is further described.

The specific embodiment
With reference to Fig. 3 to Fig. 6, present embodiment is a kind of vacuum jug, comprises kettle body 1 and pot lid, and pot lid comprises that be connected with the kettle body main covers 2, and main lid is provided with out water management kettle plug, and the top that goes out water management kettle plug is connected with loam cake 3; Go out water management kettle plug and comprise cock body 4, mandrel control assembly and button 5; The mandrel control assembly comprises mandrel 6, main spring 7, buffer spring 8 and end cover 9; Cock body is provided with the core tube 10 that mandrel is installed, and main spring is set in the top of mandrel and is in the interior position-limiting drum 11 of core tube and is arranged between the spring end cap 12 of mandrel upper end and spacing; End cover is set in the lower end of mandrel; Go along with sb. to guard him into steam between cock body and the end cover and discharge chamber 13; The lower end of mandrel is provided with breach 14 and sealing ring 15, and mandrel is broken away from end cover and is communicated with in the kettle steam 16 by breach by sealing ring when the lower slider along end cover through the elastic force of main spring and discharges chamber 13 with steam and constitute the steam releasing structure; It is outer and be between the upside of outer limited shoulder 17 of the cylindrical shell of core tube and end cover that buffer spring is set in the cylindrical shell of core tube, and the mandrel control assembly constitutes the control water flowing out structure through the moving down of elastic band movable sealing end cap of buffer spring; Mandrel 6 is set with the piston 18 that supplies mandrel in core tube 10, to slide; The periphery of end cover 9 is provided with the flexible seal ring 20 to lower limb 19 sealings of cock body.
Use of the present invention: with reference to Fig. 3 to Fig. 6, pushing button after 5, end cover 9 can not opened earlier; But mandrel 6 is moved down earlier through main spring 7; Sealing ring 15 breaks away from end cover 9 and is communicated with steam 16 and steam release chamber 13 in the kettle by breach 14, and high-temperature water vapor slowly gets into steam release chamber 13 from the breach 14 of mandrel lower end earlier in the kettle, after 0.8 ~ 1 second; When inner and outer air pressure arrives balance, open end cover 9 water outlets again by the elastic force effect of buffer spring 8; After the water outlet, pushed button 5 o'clock, main spring 7 serves as the back-moving spring role again, and it drives mandrel 6 upwards, make end cover 9 seal the lower limb 19 of cock body and seal, and sealing ring 15 is also sealed end cover 9, and breach 14 is in not connected state.
The present invention and since utilize pressure balance principle, end cover can do greatly and control ratio more laborsaving; Through main spring mandrel is moved down earlier; Elder generation's released vapour is then opened the end cover water outlet by the elastic force effect of buffer spring again, accomplishes only step control of two steps action.
