In this embodiment, there is provided a dual station showerhead, fig. 1 is an exploded schematic view of the dual station showerhead according to an embodiment of the present invention, and fig. 2 is a lateral cross-sectional view of the dual station showerhead according to an embodiment of the present invention, as shown in fig. 1 and 2, including: the spray head comprises a spray head main body 11, a spray head 12, a core tube 13, a spring 14, a limiting rod 15, an inner piston 16, an outer piston 17 and a spray head rear cover 18, wherein,
the spray head rear cover 18 is connected with the bottom of the spray head main body 11 in a matching way, and the outer piston 17 and the inner piston 16 are arranged in an inner space surrounded by the spray head rear cover 18 and the spray head main body 11; wherein, the bottom of the outer piston 17 is provided with a first groove 171, and the inner piston 16 is arranged in the first groove 171; the groove wall 1711 of the first groove 171 is in sliding fit with the rear cover 18 of the nozzle, and forms an outer air chamber 182 with the second groove 181 on the rear cover 18 of the nozzle; a third groove 161 is formed at the bottom of the inner piston 16, and a groove wall 1611 of the third groove 161 is slidably matched with the rear cover 18 of the nozzle and forms an inner air chamber with a fourth groove 183 on the rear cover 18 of the nozzle (the inner air chamber is compressed to 0 in fig. 2, and is not shown);
a through hole is formed in the center of the nozzle body 11, the nozzle rear cover 18, the outer piston 17 and the inner piston 16, and the core tube 13 passes through the through hole; the upper end of the core tube 13 is connected with the spray head 12, and the lower end of the core tube 13 is positioned in a through hole of the spray head rear cover 18;
the top surface of the outer piston 17 is fixedly connected with the core tube 13, and the spring 14 is arranged between the top surface of the outer piston 17 and the top surface of the nozzle body 11;
the top surface of the outer piston 17 is provided with a through hole, a blind hole is arranged on the top surface of the inner piston 16 at a position corresponding to the through hole on the top surface of the outer piston 17, one end of the limiting rod 15 is fixedly connected with the top surface of the spray head main body 11, and the other end of the limiting rod penetrates through the through hole on the top surface of the outer piston 17 and is in sliding fit with the blind hole.
With the above-described structure, the outer piston 17 is zero in its natural state of travel due to the action of the spring 14; meanwhile, since the outer piston 17 is connected to the core tube 13 and the upper end of the core tube 13 is connected to the spray head 12, the spray head 12 is retracted inside the spray head body 11 in a natural state. When the inner piston 16 is pushed out a certain distance and then blocked by the limiting rod 15, the outer piston 17 drives the spray head 12 to rise a certain distance because the inner piston 16 is attached to the end face of the outer piston 17, and at this time, a part of the spray head 12 can be exposed out of the spray head main body 11. When the outer piston 17 is pushed out upwards, the outer piston 17 is not limited by the limiting rod 15, so that the stroke of the outer piston is larger than that of the inner piston 16, and meanwhile, the spray head 12 is driven to rise for a certain distance, and the spray head 12 can be completely exposed out of the spray head main body 11. Therefore, through the structure, double-station of the spray head can be realized, and the chromatographic column glue filling and cleaning efficiency is improved.
Optionally, the dual-station nozzle further includes a glue inlet nozzle 21, where the glue inlet nozzle 21 is disposed at the bottom of the rear nozzle cover 18 and is in communication with the through hole of the rear nozzle cover 18. With the above structure, the nozzle 12 communicates with the glue inlet nozzle 21, and the glue solution is sprayed from the nozzle 21.
Optionally, the dual-station nozzle further comprises a chromatographic nozzle 22 and a glue discharging nozzle 23, wherein the chromatographic nozzle 22 and the glue discharging nozzle 23 are arranged on the side face of the nozzle body 11, two concentric annular channels are arranged on the top face of the nozzle body 11, one of the two annular channels is communicated with the chromatographic nozzle 22, and the other annular channel is communicated with the glue discharging nozzle 23. By the above structure, the discharging of gel from one annular channel and the ejection of chromatographic liquid from the other annular channel are realized.
Optionally, an outer annular channel of the two annular channels communicates with the chromatographic nozzle 22, and an inner annular channel of the two annular channels communicates with the glue discharge nozzle 23. The advantage of the above-described construction is that the inner annular channel can be closed by the sealing ring, while the outer annular channel remains open without being affected by the sealing ring.
Optionally, in order to enable the inner annular channel to be closed, the spray head 12 includes a top housing, a glue outlet, and a sealing ring, where the glue outlet is disposed on a side surface of the spray head 12, and the sealing ring is disposed at a bottom of the spray head 12, and the sealing ring is configured to cooperate with the inner annular channel to enable the inner annular channel to be closed.
Alternatively, the core tube 13 has a predetermined length such that the head 12 is retracted inside the head body 11 when the stroke of the outer piston 17 is zero, and the seal ring closes the inner annular passage.
Optionally, the travel of the inner piston 16 is limited by the stop lever 15; a portion of the glue outlet of the spray head 12 is exposed out of the spray head body 11 when the stroke of the inner piston 16 reaches a maximum stroke.
Optionally, the stroke of the outer piston 17 is greater than the maximum stroke of the inner piston 16; when the stroke of the outer piston 17 reaches the maximum stroke, the glue outlet of the nozzle 12 is completely exposed out of the nozzle body 11, and the sealing ring is separated from the inner annular channel, so that the inner annular channel is opened.
Through the structure of the double-station spray head described by the embodiment of the invention, double stations can be realized, and the opening and closing control of different channels can be realized, for example:
1. in the natural state, the stroke of the outer piston 17 is zero in the natural state due to the action of the spring 14; meanwhile, since the outer piston 17 is connected to the core tube 13 and the upper end of the core tube 13 is connected to the spray head 12, the spray head 12 is retracted inside the spray head body 11 in a natural state. Because the glue outlet of the spray head 12 is arranged on the side surface, the glue outlet is blocked by the through hole of the spray head main body 11, and the channel communicated with the glue spray nozzle is closed; meanwhile, the sealing ring of the spray head 12 blocks the inner annular channel, and the channel communicated with the glue discharging nozzle is closed; the channel communicating with the chromatographic nozzle remains open.
2. Referring to fig. 3, when the inner piston 16 is pushed out a distance and then blocked by the stop lever 15, the outer piston 17 will drive the spray head 12 to rise a distance because the inner piston 16 is attached to the end surface of the outer piston 17, at this time, the glue outlet of the spray head 12 can partially expose out of the spray head main body 11, and the channel communicated with the glue nozzle is opened; simultaneously, the sealing ring of the spray head 12 continuously blocks the inner annular channel, and the channel communicated with the glue discharging nozzle is continuously closed; the channel communicating with the chromatographic nozzle continues to remain open.
3. Referring to fig. 4, when the outer piston 17 is pushed up, since the outer piston 17 is not limited by the stop lever 15, its travel can be larger than that of the inner piston 16, and at the same time, the spray head 12 is driven to rise for a longer distance, and the spray head 12 can fully expose out of the spray head main body 11, and the channel communicating with the glue nozzle is kept open; simultaneously, the sealing ring of the spray head 12 is separated from the inner annular channel, and the channel communicated with the glue discharging nozzle is opened; the channel communicating with the chromatographic nozzle continues to remain open.
Therefore, through the structure, the double-station structure of the spray head can be realized. By adopting the double-station spray head, the automatic glue loading, unloading and cleaning efficiency of the chromatographic column can be improved through the cooperation of the air valve communicated with the air chamber and the liquid valve communicated with the chromatographic nozzle, the glue discharging nozzle and the glue spraying nozzle.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
