Through-hole, the core pipe 13 pass through the through-hole；The upper end of the core pipe 13 is connect with the spray head 12, the lower end of the core pipe 13
In the through-hole of the spray head rear cover 18；
The top surface of the outer piston 17 is fixedly connected with the core pipe 13, and the outer piston 17 is arranged in the spring 14
Between top surface and the top surface of the nozzle body 11；
The top surface of the outer piston 17 is equipped with through-hole, and the top of outer piston 17 is corresponded on the top surface of the inner piston 16
The position of through-hole on face is provided with blind hole, and one end of the gag lever post 15 is fixedly connected with the top surface of the nozzle body 11,
The other end passes through the through-hole on the top surface of the outer piston 17 and is slidably matched with the blind hole.
By above-mentioned structure, due to the effect of spring 14, stroke is zero to outer piston 17 in its natural state；Meanwhile by
It is connect in outer piston 17 with core pipe 13, the upper end of core pipe 13 is connect with spray head 12, therefore under natural conditions, spray head 12 is retracted in spray
Inside head main body 11.It after inner piston 16 ejects a distance, is limited bar 15 and blocks, due to inner piston 16 and outer piston 17
End face fitting, therefore outer piston 17 also will drive spray head 12 rise a distance, at this point, spray head 12 can a part manifest spray
Except head main body 11.When outer piston 17 ejects upwards, due to the limitation of 17 unrestricted bars of outer piston 15, stroke can compare
Inner piston 16 is bigger, while spray head 12 being driven to rise more a distances, and spray head 12 can manifest nozzle body 11 completely
Except.As it can be seen that can be realized the double-station of spray head by above-mentioned structure, chromatographic column dress glue and cleaning efficiency are improved.
Optionally, the double-station spray head further include into glue mouth 21, it is described to be arranged into glue mouth 21 in the spray head rear cover 18
Bottom, and be connected to the through-hole of the spray head rear cover 18.By above structure, spray head 12 is connected into glue mouth 21, realize from
Spray head 21 sprays glue.
Optionally, the double-station spray head further includes chromatography mouth 22 and dumping mouth 23, the chromatography mouth 22 and the dumping
The side of the nozzle body 11 is arranged in mouth 23, wherein the top surface of the nozzle body 11 sets that there are two concentric annular is logical
Road, a circular passage in described two circular passages are connected to the chromatography mouth 22, another circular passage and the row
Glue mouth 23 is connected to.By above-mentioned structure, realizes from a circular passage dumping and spray layer from another circular passage
Analyse liquid.
Optionally, the outer annular channel in described two circular passages is connected to the chromatography mouth 22, described two annulars
Annular channel in channel is connected to the dumping mouth 23.The advantages of above structure, is that annular channel can pass through sealing
Circle closing, and outer annular channel is not influenced by sealing ring and is stayed open.
Optionally, in order to realize the closing in annular channel, the spray head 12 includes top shell, gum outlet and close
Seal, wherein the side of the spray head 12 is arranged in the gum outlet, and the bottom of the spray head 12 is arranged in the sealing ring,
The sealing ring is used to cooperate with the annular channel, to realize the closing to the annular channel.
Optionally, the core pipe 13 has a predetermined length, and the predetermined length makes the stroke when the outer piston 17 to be
The contracting of spray head 12 is inside the nozzle body 11 when zero, and the sealing ring closes the annular channel.
Optionally, the stroke of the inner piston 16 is limited by the gag lever post 15；When the stroke of the inner piston 16
A part of gum outlet of the spray head 12 is exposed to except the nozzle body 11 when reaching range.
Optionally, the stroke of the outer piston 17 is greater than the range of the inner piston 16；When the outer piston 17
Stroke when reaching range the gum outlet of the spray head 12 be all exposed to except the nozzle body 11, and the sealing ring
It is detached from the annular channel, so that the annular channel is opened.
The structure of the above-mentioned double-station spray head described through the embodiment of the present invention may be implemented double-station and realize different logical
The open and close control in road, such as:
1, in its natural state, due to the effect of spring 14, stroke is zero to outer piston 17 in its natural state；Meanwhile by
It is connect in outer piston 17 with core pipe 13, the upper end of core pipe 13 is connect with spray head 12, therefore under natural conditions, spray head 12 is retracted in spray
Inside head main body 11.Since the gum outlet setting of spray head 12 is in side, is blocked by the through-hole of nozzle body 11, communicated with glue-spraying spout
Channel enclosed；Meanwhile the sealing ring of spray head 12 blocks annular channel, the channel enclosed communicated with dumping mouth；With chromatography mouth
The channel communicated stays open.
2, it is limited bar 15 after inner piston 16 ejects a distance with reference to Fig. 3 and blocks, due to inner piston 16 and outer work
The end face fitting of plug 17, therefore outer piston 17 will also drive spray head 12 to rise a distance, at this point, the gum outlet of spray head 12 can be with
A part manifests except nozzle body 11, and the channel communicated with glue-spraying spout is opened；Meanwhile the sealing ring of spray head 12 continues to block
Annular channel, the channel communicated with dumping mouth continue to close；Continue to stay open in the channel communicated with chromatography mouth.
3, with reference to Fig. 4, when outer piston 17 ejects upwards, due to the limitation of 17 unrestricted bars of outer piston 15, stroke
Can be bigger than inner piston 16, while spray head 12 being driven to rise more a distances, spray head 12 can manifest spray head completely
Except main body 11, the channel communicated with glue-spraying spout continues to stay open；Meanwhile the sealing ring of spray head 12 is detached from annular channel,
It opens in the channel communicated with dumping mouth；Continue to stay open in the channel communicated with chromatography mouth.
As it can be seen that can be realized the double-station of spray head by above-mentioned structure.Using the double-station spray head, by with gas chamber
The cooperation of the air valve of connection and the liquid valve being connected to chromatography mouth, dumping mouth, glue-spraying spout, can be improved chromatographic column automatically fill glue,
Unload the efficiency of glue and cleaning.
These are only the preferred embodiment of the present invention, is not intended to restrict the invention, for those skilled in the art
For member, the invention may be variously modified and varied.All within the spirits and principles of the present invention, it is made it is any modification,
Equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
