Detailed Description
In order to make the technical field person understand the scheme of the present invention better, the technical scheme in the embodiment of the present invention will be clearly and completely described below with reference to the attached drawings in the embodiment of the present invention. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the invention. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein may be combined with other embodiments.
Referring to fig. 1 to 3, an embodiment of the present invention provides a cotton swab needle, including: the syringe comprises a syringe 10, a needle head 20 and a cotton sleeve 30, wherein a glue inlet is formed in the glue inlet end of the syringe 10, and the glue inlet end of the syringe 10 is used for being connected with glue dispensing equipment so as to introduce glue into the syringe 10; as shown in fig. 1, a clamping block 101 adapted to a glue outlet valve of the glue dispensing device is disposed at an end of the syringe 10. In this way, the cotton tip 20 may be connected to a dispensing device, through which glue is injected into the syringe 10.
The needle 20 is connected with the other end of the needle cylinder 10, the needle 20 is provided with a glue outlet hole 201, and the glue outlet hole 201 is communicated with a glue inlet of the needle cylinder 10 so as to lead out glue; the needle 20 is connected to the barrel 10. In one embodiment of the present invention, the barrel 10 and the needle 20 are integrally formed, so as to reduce assembly. Since the glue outlet 201 is communicated with the glue inlet of the needle cylinder 10. After passing through the glue inlet, the glue enters the syringe 10 through the glue inlet and flows out through the glue outlet 201.
The cotton sleeve 30 is arranged on the outer surface of the needle 20 and surrounds the glue outlet 201. In one embodiment of the invention, as shown in fig. 1 and 2, the cotton cap 30 is fitted over the upper surface of the needle 20. In this way, during dispensing, the glue can overflow from the glue outlet 201 and can be relatively uniformly brushed onto the upper surface of the dispensed component through the cotton sleeve 30 by permeating into the cotton sleeve 30. Because the cotton sleeve 30 is made of soft materials, hard contact between the dispensing head and the dispensed component can be reduced, and the problem that the dispensing surface of the dispensed component is scratched is avoided.
The cotton swab needle head 20 provided by the embodiment of the present invention is provided with a glue inlet through the glue inlet end of the needle cylinder 10, and the glue inlet end of the needle cylinder 10 is used for connecting with a glue dispensing device so as to introduce glue into the needle cylinder 10; the needle head 20 is connected with the other end of the needle cylinder 10, the needle head 20 is provided with a glue outlet hole 201, and the glue outlet hole 201 is communicated with a glue inlet of the needle cylinder 10 so as to lead out glue; the cotton sleeve 30 is arranged on the outer surface of the needle 20 and surrounds the glue outlet hole 201. Therefore, when dispensing, the hard contact between the dispensing head and the dispensed component can be reduced, and the problem that the dispensing surface of the dispensed component is scratched is avoided. In addition, the glue led out from the glue outlet 201 is diffused all around through the cotton sleeve 30, so that the glue dispensing is uniform.
Referring to fig. 2, the needle 20 is of a flat configuration. By providing the needle 20 in a flat configuration, the end of the dispensing tip does not spill a significant amount of glue. The phenomenon that a large amount of glue overflows on the surface of the glue dispensing assembly is avoided. The flat structure makes the glue at the dispensing more uniform.
Referring to fig. 2, the glue outlet 201 is disposed at an end of the needle 20 connected to the barrel 10. Since the glue outlet 201 is far away from the glue dispensing end of the needle 20. After the glue comes out from the glue outlet 201, the glue permeates into the cotton sleeve 30 and permeates the whole cotton sleeve 30 under the action of gravity, so that the glue is more uniformly discharged.
In an embodiment of the present invention, the glue outlet 201 is a through hole. By setting the glue outlet 201 as a through hole, the glue can overflow from both sides of the needle 20 in the flat structure. Can uniformly permeate into the cotton sleeve 30 and permeate the whole cotton sleeve 30 under the action of gravity, thereby leading the glue to be discharged more uniformly.
A first line groove 202 and a second line groove are respectively arranged on two surfaces of the needle 20, one end of each of the first line groove 202 and the second line groove is respectively communicated with the through hole, and the first line groove 202 and the second line groove extend to the other end of the needle 20. The glue can flow along the first line grooves 202 and the second line grooves under the action of gravity, and when the glue fills the line grooves, the glue overflows all around, so that the whole cotton sleeve 30 can be penetrated more quickly.
The periphery of the other end of the needle 20 is a round chamfer. The needle 20 is rounded around the needle 20, so as to further avoid scratching the needle 20 by the dispensing component.
The needle cylinder 10 is internally provided with: the first glue outlet channel is communicated with the glue inlet; the second glue outlet channel is communicated with the first glue outlet channel; the third glue outlet channel is communicated with the second glue outlet channel and the glue outlet hole 201, the diameter of the cross section of the first glue outlet channel is larger than that of the cross section of the second glue outlet channel, and the diameter of the cross section of the second glue outlet channel is larger than that of the cross section of the third glue outlet channel. And the overflow of the glue is controlled through the first glue outlet channel, the second glue outlet channel and the third glue outlet channel.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and equivalent substitutions can be made on the technical solutions described in the foregoing embodiments or some technical features thereof. All utilize the equivalent structure that the content of the utility model discloses a specification and attached drawing was done, direct or indirect application is in other relevant technical field, all is in the same way the utility model discloses within the patent protection scope.
