Abstract
The utility model discloses a dust blowing gun, which belongs to the technical field of dust blowing guns. Moreover, the needle point through hole of the hollow needle head is in a blocking state, and the air outlet holes are uniformly distributed at intervals along the axial direction of the hollow needle head. The nozzle of the dust blowing gun can extend into the hole with smaller diameter to clean impurities, so that the problem that the traditional dust blowing gun cannot extend into the hole with smaller diameter to clean impurities due to overlarge nozzle diameter is solved.
Description
Technical Field
The utility model belongs to the technical field of dust blowing guns, and particularly relates to a dust blowing gun with a hollow needle.
Background
At present, a main function of a common dust blowing gun is to clean the surface or a smooth inner hole of a part, but the inner hole of a thread with a smaller diameter cannot be cleaned. Particularly, for the method for cleaning the scraps left in the threaded holes, particularly the deep blind holes, after tapping the unthreaded holes, one method is to repeatedly pass the screw tap so as to bring the scraps out when the screw tap passes into and out of the threaded holes, but the method is labor-consuming and labor-consuming, and cannot guarantee the cleaning effect, and the other method is to blow the scraps into the holes by using a dust blowing gun after the impurities are softened by using a kerosene soaking threaded hole, but the method cannot stretch into the threaded holes due to the fact that the diameter of a spray head of the dust blowing gun is too large, so that the tiny scraps remained at the bottom of the spiral groove cannot be cleaned.
Disclosure of Invention
In view of the above, the utility model provides a dust blowing gun, wherein a nozzle of the dust blowing gun can extend into a hole with smaller diameter to clean impurities, and the problem that the traditional dust blowing gun cannot extend into the hole with smaller diameter to clean impurities due to overlarge diameter of the nozzle is solved.
The utility model adopts the following technical scheme:
a dust blowing gun, wherein the tail end of a spray head of the dust blowing gun is connected with a hollow needle head in a threaded manner;
the pipe wall of the hollow needle is provided with an air outlet hole which is used as an air flow outflow channel.
Further, the needle point through hole of the hollow needle head is in a blocking state.
Further, the air outlet holes are uniformly distributed at intervals along the axial direction of the hollow needle head.
Further, the device also comprises a threaded pipe and a threaded sleeve;
the threaded pipe is provided with a threaded pipe through hole along the axis, and one end of the threaded pipe is fixedly connected with a spray head of the dust blowing gun;
the thread sleeve is provided with a thread sleeve through hole along the axis, and one end of the thread sleeve is in threaded connection with the other end of the thread pipe;
the medical injection needle is in threaded connection with the other end of the threaded sleeve, and the threaded pipe through hole, the threaded sleeve through hole and the air outlet hole are communicated with the air outlet channel of the dust blowing gun nozzle.
Further, the hollow needle is a medical injection needle.
The beneficial effects are that:
1. the end of the spray head of the dust blowing gun is in threaded connection with the hollow needle, and the pipe wall of the hollow needle is provided with an air outlet hole serving as an air flow outflow channel, so that the hollow needle can be stretched into a hole with smaller diameter to clean impurities, and the hollow needle is in threaded connection with the end of the spray head of the dust blowing gun, so that the hollow needles with different diameters and different lengths can be flexibly replaced according to workpieces to be cleaned.
2. The needle point through hole of the hollow needle head is in a blocking state, so that the air flow of the dust blowing gun can only flow out from the air outlet hole on the wall of the hollow needle head, and the discharge of impurities in the tiny holes is facilitated.
3. The air outlet holes are uniformly distributed at intervals along the axial direction of the hollow needle head, so that impurities in the tiny holes can be discharged by air flow flowing out of the air outlet holes, and the cleaning effect is improved.

FIG. 1 is a schematic view of a hollow needle mounting structure of a dust gun according to an embodiment of the present utility model;
in fig. 2, (a) is a front view of the hollow needle of fig. 1, (b) is a left side view of the hollow needle of fig. 1;
FIG. 3 is an exploded view of FIG. 1;
wherein, the needle comprises a 1-threaded tube, a 2-threaded sleeve and a 3-hollow needle.
Detailed Description
The utility model will now be described in detail by way of example with reference to the accompanying drawings.
As shown in fig. 1 to 3, a dust blowing gun is provided, wherein the tail end of a spray head of the dust blowing gun is in threaded connection with a hollow needle head 3, and the pipe wall of the hollow needle head 3 is provided with a plurality of air outlet holes serving as air flow outflow channels.
So, can stretch into the clearance of impurity in the less downthehole of diameter with hollow syringe needle 3, moreover, hollow syringe needle 3 and blow the terminal threaded connection of shower nozzle of dirt rifle, this makes can change the hollow syringe needle 3 of different diameters and different length in a flexible way according to the work piece of waiting to clear up. In addition, to some work pieces that are not suitable for using hollow syringe needle 3 to clear up, can also take off hollow syringe needle 3 from blowing the shower nozzle of dirt rifle, change the traditional shower nozzle of dirt rifle that blows, convenient nimble, moreover, can also assemble this hollow syringe needle 3 to the water pump rifle head, clean the work piece through the rivers that flow from the venthole.
In this embodiment, the hollow needle 3 is connected to the end of the nozzle of the dust blowing gun through the threaded tube 1 and the threaded sleeve 2, specifically, the threaded tube 1 is provided with a threaded tube through hole along the axis, one end of the threaded tube 1 is fixedly connected with the nozzle of the dust blowing gun, the threaded sleeve 2 is provided with a threaded sleeve through hole along the axis, one end of the threaded sleeve 2 is in threaded connection with the other end of the threaded tube 1, the hollow needle 3 is in threaded connection with the other end of the threaded sleeve 2, and the threaded tube through hole, the threaded sleeve through hole, the air outlet hole and the air outlet channel of the nozzle of the dust blowing gun are communicated.
As an improvement, the needle point through hole of the hollow needle head 3 is in a blocking state, so that the air flow of the dust blowing gun can only flow out from the air outlet hole on the pipe wall of the hollow needle head 3, and the discharge of impurities in the tiny holes is facilitated.
As a further improvement, the air outlet holes on the wall of the air needle 3 are uniformly distributed at intervals along the axial direction of the hollow needle 3, so that impurities in the tiny holes can be discharged by the air flow flowing out of the air outlet holes, and the cleaning effect is improved.
In addition, in the present embodiment, the hollow needle 3 is a medical injection needle.
The using method of the dust blowing gun is as follows: the hollow needle 3 stretches into the tiny holes, a spanner of the dust blowing gun is buckled, high-pressure gas is generated through the dust blowing gun, the high-pressure gas flows out from the air outlet holes on the wall of the hollow needle 3 at a high speed, and at the moment, sundries adsorbed in the tiny holes are discharged by manually rotating the dust blowing gun.
In summary, the above embodiments are only preferred embodiments of the present utility model, and are not intended to limit the scope of the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
