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 shown in Fig. 1, Fig. 2, and in the time that kettle packs boiling water into, kettle internal upper part is full of water vapour, in the time pushing button, end cover throws open, and the water vapour in kettle just gushes out quickly, take sb. aback, because water vapour discharges fast, also can scald people; Meanwhile, traditional control structure, owing to there being end cover inside and outside differential pressure, end cover can not do greatly and control ratio is required great effort.
Summary of the invention
The object of the invention is for above-mentioned existing problems, a kind of control laborsaving, safe, anti-scald vapor-proof vacuum jug and pot lid thereof are provided.
The present invention, it is such realizing above-mentioned object: comprise kettle body and pot lid, pot lid comprises the main lid being connected with 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 upper cover; Go out water management kettle plug and comprise cock body, mandrel control assembly and button; Mandrel control assembly comprises mandrel, main spring, buffer spring and end cover; Cock body is provided with installs the core cylinder of mandrel, and main spring is set in the top of mandrel the interior position-limiting drum in core cylinder and is arranged between the spring end cap of mandrel upper end and spacing; End cover is set in the lower end of mandrel, between cock body and end cover, go along with sb. to guard him into steam and discharge chamber, the lower end of mandrel is provided with breach and sealing ring, and mandrel is departed from end cover and is communicated with in kettle steam and steam by breach by sealing ring during along end cover down sliding by the elastic force of main spring and discharges chamber and form steam releasing structure; Buffer spring is set between the limited shoulder and the upside of end cover outside the outer and cylindrical shell in core cylinder of the cylindrical shell of core cylinder, and mandrel control assembly forms control water flowing out structure by the moving down of elastic band movable sealing end cap of buffer spring.
The present invention, the piston sliding in core cylinder for mandrel is equipped with in 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 of the lower limb sealing to cock body, makes sealing effectiveness better.
The present invention, because steam and steam in employing breach connection kettle discharge the steam releasing structure of chamber, after pushing button, end cover first can not be opened, but by main spring, mandrel first being moved down, in kettle, high-temperature water vapor first slowly enters steam release chamber from the small gap of mandrel lower end, after 0.8 ~ 1 second, when inner and outer air pressure arrives balance, open again end cover water outlet by the elastic force effect of buffer spring; More traditional control structure, the present invention, the then water outlet of first released vapour, completes two only step controls of step action, simultaneously, owing to considering internal and external pressure balance principle, so end cover also can do greatly and control ratio is more laborsaving, and traditional control structure, owing to there being inside and outside differential pressure, end cover can not do greatly and control ratio is required great effort, so the present invention also has significant good effect.
The present invention, has advantages of that control is laborsaving, safe, anti-scald.
The present invention is further illustrated by reference to the accompanying drawings for embodiment below.

Detailed description of the invention
With reference to Fig. 3 to Fig. 6, the present embodiment is a kind of vacuum jug, comprises kettle body 1 and pot lid, and pot lid comprises the main lid 2 being connected with 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 upper cover 3; Go out water management kettle plug and comprise cock body 4, mandrel control assembly and button 5; Mandrel control assembly comprises mandrel 6, main spring 7, buffer spring 8 and end cover 9; Cock body is provided with installs the core cylinder 10 of mandrel, and main spring is set in the top of mandrel the interior position-limiting drum 11 in core cylinder 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, between cock body and end cover, go along with sb. to guard him into steam and discharge chamber 13, the lower end of mandrel is provided with breach 14 and sealing ring 15, and mandrel is departed from end cover and is communicated with in kettle steam 16 and steam by breach by sealing ring during along end cover down sliding by the elastic force of main spring and discharges chamber 13 and form steam releasing structure; Buffer spring is set between the limited shoulder 17 and the upside of end cover outside the outer and cylindrical shell in core cylinder of the cylindrical shell of core cylinder, and mandrel control assembly forms control water flowing out structure by the moving down of elastic band movable sealing end cap of buffer spring; Mandrel 6 is set with the piston 18 sliding in core cylinder 10 for mandrel; The periphery of end cover 9 is provided with the flexible seal ring 20 that the lower limb 19 of cock body is sealed.
Use procedure of the present invention: with reference to Fig. 3 to Fig. 6, pushing button after 5, end cover 9 first can not be opened, but by main spring 7, mandrel 6 is first moved down, sealing ring 15 departs from end cover 9 and is communicated with steam 16 and steam release chamber 13 in kettle by breach 14, and in kettle, high-temperature water vapor first slowly enters steam release chamber 13 from the breach 14 of mandrel lower end, after 0.8 ~ 1 second, when inner and outer air pressure arrives balance, open again end cover 9 water outlets by the elastic force effect of buffer spring 8; After water outlet, then push button 5 o'clock, main spring 7 serves as back-moving spring role, and Qi Dai moving mandrel 6 upwards, make end cover 9 seal the lower limb 19 of cock body and seal, and sealing ring 15 also seals end cover 9, and breach 14 is in connected state not.
