Description
Technical field
The utility model relates to a kind of restaurant burner for kitchen use, particularly a kind of pair of premix electrospray burner.
Background technology
Burner of the prior art includes the igniting core, and the igniting core is with sleeve pipe outward in order to protection igniting core.With adopt ceramic package and metal-cored process, when owing to burner using, do not protect usually by its igniting core upper end for the igniting core, and the ceramic package upper end of igniting core contacts with a pot body lower end easily.Because ceramic material is impact resistance not, therefore pot cognition crashes pottery, and the core upper end of will lighting a fire fractures, thereby reduces the service life of burner.
Summary of the invention
The utility model provides a kind of pair of premix electrospray burner, and purpose is to solve the prior art problem, and the igniting core upper end in this burner adds seedling fire cover and seedling fire lid, can prevent that the igniting core in the burner from being fractureed.
The utility model technical scheme that adopts of dealing with problems is:
Two premix electrospray burners include base, set up a ring flange on the base; Set up successively in the ring flange and expanded air port, ignition dish, expanded between air port and the ignition dish and form mixing bunker, passed base successively, expand air port, ring flange, ignition dish by the metal-cored igniting core that constitutes with ceramic package; The outer sheathed sleeve pipe of igniting core, its igniting core upper end extends to outside the sleeve pipe, also includes seedling fire cover and seedling fire lid; The outer igniting core that is sheathed on of seedling fire cover is sheathed on sleeve pipe in the while, and seedling fire cover middle part has a boss; The lower surface of its seedling fire cover boss contacts with the cannula tip end face, makes seedling fire cover inside form one with inside pipe casing and connects and airtight space; The seedling fire covers on seedling fire cover top, and the bottom end face of its seedling fire lid contacts with the upper surface of seedling fire cover boss, and seedling fire lid inwall and seedling fire cover outer wall form a space; On seedling fire cover top sidewall and seedling fire lid lower sides, offer several through holes respectively, the extraneous air environment is communicated with inside pipe casing.
Seedling fire cover bottom outer wall is provided with external screw thread, and this external screw thread matches with the internal thread that sleeve pipe top is provided with.
Said through hole is offering along seedling fire cover and seedling fire lid in one week of sidewall respectively.
Said through hole is evenly offering along seedling fire cover and seedling fire lid in one week of sidewall respectively.
The beneficial effect of the utility model: sheathed seedling fire cover and seedling fire lid outside the top of igniting core; Under the situation that does not influence the normal use of burner, strengthened protection to the igniting core; The core that prevents to light a fire is fractureed easily, thereby has reduced cost the service life that has strengthened burner.

The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is explained further details.
Two premix electrospray burners shown in Fig. 1 to Fig. 5; Include base 9, set up a ring flange 10 on the base 10, set up successively in the ring flange 10 and expanded air port 11, ignition dish 12; Expand and form mixing bunker 13 between air port 11 and the ignition dish 12; Pass base 9, ring flange 10 successively, expand air port 11, ignition dish 12 by the metal-cored igniting core 1 that constitutes with ceramic package, igniting core 1 outer sheathed sleeve pipe 2, its igniting core 1 upper end extends to outside the sleeve pipe 2.Also include seedling fire cover 3 and cover 4 with the seedling fire, the seedling fire cover 3 outer igniting cores 1 that are sheathed on are sheathed on sleeve pipe 2 in the while.The seedling fire overlaps 3 middle parts and has a boss 3, and the lower surface 33 of its seedling fire cover boss 31 contacts with cannula tip end face 20, and the fiery cover of seedling 3 inside and sleeve pipe 2 one of inner formation are connected and airtight space, and purpose is to prevent to feed the gas leakage in the sleeve pipe.Seedling fire lid 4 covers on seedling fire cover 3 tops, and the bottom end face 41 of its seedling fire lid 4 contacts with the upper surface 32 of seedling fire cover boss 31, and seedling fire lid inwall 7 forms a space 6 with seedling fire cover outer wall 8.Wherein the fixing mode of seedling fire cover 3 and sleeve pipe 2 has multiplely, can seedling fire cover 3 directly be erected in the sleeve pipe 2, in order to make being connected firmly of seedling fire cover 3 and sleeve pipe 2, also can both be fastened on together through the buckle mode.Adopt the mode that both are arranged in together to be set-located in the present embodiment, be provided with external screw thread 5 at seedling fire cover 3 bottom outer walls, this external screw thread 5 matches with the internal thread (not shown) that sleeve pipe 2 tops are provided with.
Thereby, the combustion gas that feeds inside pipe casing lights for being contacted with the outside air environment facies; Offer several through holes 30 in seedling fire cover 3 upper portion side wall; On Miao Huogai 4 lower sides, offer several through holes 40; Because between Miao Huogai inwall 7 and seedling fire cover outer wall 8, have space 6, so through hole 30 can be corresponding one by one with through hole 40, the combustion gas that feeds in the sleeve pipe 2 can be passed through outside through hole 30, space 6, through hole 40 to the seedling fire lid 4.
Above-mentioned through hole 30 and through hole 40 are the lighting-up tuyere of igniting core 1.When the igniting of igniting core 1, the combustion gas that feed in the sleeve pipe 2 are lighted at through hole 30,40 places, and the flare of lighting makes rapidly gets angry the combustion of making an inventory.Get angry the combustion of making an inventory in order to make fast, through hole 30, through hole 40 cover 4 evenly offering in one week of sidewall along seedling fire cover 3 and seedling fire respectively.
Overlap inside, when inside pipe casing all connects, also can only on the sidewall of Miao Huogai 4, offer through hole 40. with the seedling fire when space 6
Because be provided with seedling fire cover 3 and seedling fire lid 4 in igniting core 1 upper end, the pot body can not come in contact with igniting core 1, the ceramic coat of igniting core 1 is crashed, igniting core 1 is fractureed, increased the service life of burner.
