Detailed Description

Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.

As shown in fig. 1 to fig. 6, it is a schematic structural diagram of a suction pen with an ejection mechanism provided by the present invention. The suction pen with the ejection mechanism comprises a shell 10, a suction assembly 20 arranged in the shell 10, and an abutting assembly 30 connected with the suction assembly 20. It is understood that the suction pen with the ejection mechanism further includes other functional modules, such as a power supply connection, an air pump and an air tube, etc., which are well known to those skilled in the art and will not be described herein again.

The housing 10 includes a housing body 11, a bottom case 12 located at one end of the housing body 11, a clamping housing 13 located at one end of the bottom case 12 far away from the housing body 11, and a clamping bottom case 14 located at one end of the housing body 11 far away from the clamping housing 13. The housing body 11 is a hollow cylindrical structure made of plastic or stainless steel and the like, and is used for holding by an operator when the device is used. The bottom shell 12 is a circular plastic sheet fixed to the end of the shell body 11 by a fastener, and is used for sealing the shell body, and a circular hole for an air suction pipe to pass through is formed in the center of the circular plastic sheet. The clamping shell 13 is a cylinder consistent with the shell body 11, and the clamping shell 13 is fixedly connected with the shell body 11 so as to fix the air suction component 20 and the abutting component 30 in the clamping shell 13. The clamping shell bottom 13 is consistent with the bottom shell 12, and a circular hole extending out of the air suction assembly 20 is formed in the circle center of the clamping shell bottom 13.

The air suction assembly 20 includes a pen point 21 located inside the clamping housing 13, an air suction channel 22 disposed inside the pen point 21, a plurality of air holes 23 disposed on the air suction channel 22, and an air nozzle 24 located in the hollow portion inside the housing body 11. One end of the pen point 21 extends out of a hole in the circle center of the clamping bottom shell 13, is in a solid cylinder shape and is a solid end; the other end is fixed in the clamping shell 13, and the end is in a hollow cylinder shape and is a hollow end. The diameter of the pen point 21 is gradually reduced from a hollow end to a solid end, and the diameter of the pen point 21 is sequentially the pen point tail part 211 with the largest diameter, the pen point middle part 212 with the diameter smaller than the pen point tail part 211, and the pen point end part 213 with the diameter smaller than the pen point middle part 212. The pen point tail part 211 is abutted against the clamping shell 13 and buckled with each other to ensure that the pen point 21 cannot slide up and down in the clamping shell. The air suction channel 22 is a circular hole located at the center of the pen point 21 and facing the housing 11, and is located in the tail 211 and the middle 212 of the pen point. The air hole 23 is arranged at the bottom of the air suction channel 22 far away from the tail part 211 of the pen point, so that the air suction channel 22 is communicated with the outside of the pen point 21. The air nozzle 24 is disposed at an opening of the air suction channel 22 close to the housing 11, and is hermetically connected to the pen point 21, so that an air tube can be inserted into the air nozzle 24 to suck air from the air suction channel 22 without air leakage.

The abutting assembly 30 comprises a sliding sleeve rod 31 sleeved outside the pen point 21, a limiting ring 32 arranged on the sliding sleeve rod 31, two sealing rings 33 arranged between the pen point 21 and the sliding sleeve rod 31, and a return spring 34 arranged between the end of the sliding sleeve rod 31 and the pen point 21. The sliding sleeve rod 31 is sleeved on the pen point 21 and arranged at an interval with the pen point 21, so that an air channel 311 is formed between the sliding sleeve rod 31 and the pen point 21, and the air channel 311 is communicated with the air hole 23. The sliding sleeve rod 31 extends out from one end of the pen point end part 213 far away from the pen point middle part 212, the extending length is consistent with the thickness of the copper ring, and a structure that the pen point middle part 212 is retracted in the sliding sleeve rod 31 is formed, so that the copper ring is just adsorbed at the pen point when the suction pen is used. The limiting ring 32 is fixed on the rod body of the sliding sleeve rod 31 extending out of the hole of the circle center of the clamping bottom shell 13, so that the limiting ring 32 is shifted to drive the sliding sleeve rod 31 to slide up and down on the pen point 21. Sealing ring 33 is rubber or silica gel material, and it sets up nib 21 between the slip loop bar 31, and be located being close to of gas pocket 23 one side of air cock 24 is in order to seal slip loop bar 31 upper portion space, make air intake passage 22 with air passage 311 communicates with each other. The return spring 34 is disposed at the bottom of the sliding sleeve rod 31 at the end far from the limit ring 32 and between the steps formed at the junction of the sliding sleeve rod 31 and the pen point tail 211 and the pen point middle 212, so that the sliding sleeve rod 31 returns to the original position under the elastic force of the return spring 34 after pushing the limit ring 32 to slide upwards.

It is contemplated that when the suction pen is in use, the abutting assembly 30 is in an initial state, and air is sucked from the air suction passage 22 to the air passage 311 connected to the air hole 23 by the air pump. When the copper column is sucked, the copper column can block the pen point formed between the pen point end part 213 and the sliding sleeve rod 31 so as to block the air channel 311, and the copper column is sucked at the pen point formed between the pen point end part 213 and the sliding sleeve rod 31 through air suction; when the copper cylinder needs to be taken out after the suction is finished, the sliding sleeve rod 31 can be driven to slide towards the shell 10 only by pushing the limiting ring 32 towards the shell 10, and the pen point is pushed out outwards after the pen point end part 213 is retracted in the sliding sleeve rod 31, so that the copper cylinder is pushed out. Since the copper pillar originally blocks the air channel 311, when the nib end 213 is ejected, air leaks from the nib end 213 and the sliding sleeve rod 31, and the suction force to the copper ring cannot be maintained, so that the copper ring can automatically fall down; after the copper ring is taken down, the limit ring 32 stops being pushed, and the sliding sleeve rod 31 returns to the initial state under the elastic force action of the reset spring 34, so that the next copper ring can be sucked.

Compared with the prior art, the utility model provides a suction pen with ejection mechanism establishes through setting up a cover sliding sleeve 31 on the nib 21, with the subassembly 20 that breathes in forms air channel 311, just nib tip 213 length is less than sliding sleeve 31 to form a nib that more enough holds the copper ring, extract the air through the air pump and adsorb the copper ring in nib department. Through a setting, be in spacing ring 32 on the slip loop bar 31 makes and to promote slip loop bar 31 is in slide on the nib 21, thereby use nib 21 is with the ejecting nib of copper ring, reaches and realizes taking off the function of copper ring without closing the air pump, guarantees the efficiency of assembly line work, can reduce the air pump simultaneously and open and stop the number of times, reduce cost.
