New description: [New technical field] The friend-creation system and portable pneumatic tools _, especially a kind of noise-cancelling device that can eliminate the noise generated by exhaust gas discharge. [Prior Art] Pneumatic tools such as pneumatic screwdrivers and pneumatic heads are used to provide high torque output, and they are not as troublesome as batteries and batteries, so they are widely welcomed by the factory. A large number of industries use. As shown by the force difference, the pneumatic tool 1 uses the pressure difference of the gas to push the work 4 to rotate, and the tail of the pneumatic tool 会 will be provided - the air inlet 2 and the - domain π 3 'slit gas are entered by the air inlet 2 The pneumatic tool 1 is used to push the working head 4 to rotate, and the gas discharged from the air outlet 3 is generally referred to as exhaust gas, and when the exhaust gas is discharged, considerable noise is generated due to friction with the empty milk. The long-term work of the staff in the environment of exhaust noise will have a negative impact on the auditory, psychological and physiological aspects of the staff. Your friend, the creator of this case has been relying on his years of experience in producing similar products. He has finally developed and has a practical effect. [New content] The main purpose of this creation is to provide a pneumatic tool with sound-absorbing function, including - pneumatic tool. One end of the pneumatic tool is provided with an air inlet and an air outlet of M330898, and the air inlet is connected. An intake pipe, the air outlet is connected to a muffler, and the air intake pipe passes through the center of the muffler, and the outer wall of the muffler is a concave-convex wave tube, and the domain is covered with a scale; the sound material, the silencer The outer peripheral wall is distributed with a plurality of venting holes, and the number of the Weikong holes is increased from the top to the bottom, so that part of the exhaust gas is first discharged from a plurality of upper vent holes, and the remaining exhaust gas is completely released by the plurality of vent holes below, so that Avoid the exhaust gas being blocked and can not be discharged and can prevent the exhaust gas from being released too quickly. The noise problem cannot be completely eliminated. In order to enable your review board to gain a deeper understanding and recognition of the features, purposes and functions of this creation, _ _ preferred embodiment and with the following description: [Embodiment] Please refer to "2- 1 and 2_2 show a 'pneumatic tool with a muffling effect, comprising: a pneumatic tool 1 〇, one end of the pneumatic tool 10 is provided with an air inlet u and an air outlet 12, the air inlet The port u* is connected to an air inlet pipe 20, and the air outlet port 12 is connected to the muffler cylinder 30, and the air inlet & 20 is connected to the air inlet port 11 of the air tool cartridge through the center of the muffler cylinder 3; The outer wall of the muffler cylinder 30 is a concave-convex wave tube, and the inside of the muffler cylinder 3 is filled with the sound-absorbing material 31 of the foam, and the outer peripheral wall of the muffler cylinder 30 is distributed with a hard row of IL holes 32, and the hybrid As the "3" is gradually increased, the upper wall 33 of the muffler cylinder 30 is a hollow body, the inside of which is not filled with the sound absorbing material 31, and the outer wall of the upper pipe wall 33 is not provided with 6 M330898. The exhaust hole 32 is a sealing wall of the earth, and the exhaust gas discharged from the pneumatic tool 1 can be accommodated. With the above structure, the exhaust of the employee's job will be entered into the 3G in the tactile cylinder, and the wall 33 of the upper section of Na Xiaoyin (10) can be used as a hollow body to accommodate the exhaust of the hard force. The exhaust gas of the upper wall 33 of the muffler cylinder 30 enters the lower sound absorbing material 31, and is released by the vent hole 32 of the external damper 30 to eliminate the noise. Gradually increase in the next part. Therefore, some of the exhaust gas with pressure will be discharged from the upper part of the exhaust hole 32, and the exhaust gas of the surface will be led out by the plurality of exhaust holes 32 below the (4) sound tube 3, thereby gradually letting the exhaust gas The upper and lower discharges are as follows. The number of the exhaust holes 32 of the outer peripheral wall of the creation muffler 30 is prevented from being exhausted by the upper side when the exhaust gas enters the body. There is still a noise problem with the venting of the vent hole above the damper 3G. In addition, when the pneumatic tool 10 is in operation, the exhaust gas having a considerable pressure enters the inside of the air-removing cylinder 30, and a vibration phenomenon occurs. At this time, the outer peripheral wall of the muffler cylinder 30 can be elastically stretched and designed by the concave-convex wave tube. Shock absorption function. As far as knowing, this creation has been sampled and illustrated as a sample and has been tested for many times to prove that it can achieve its intended purpose and efficacy. The value of shelling has considerable market development potential. Before the application, the famous workers and the bulletin did not find the same or similar products, and filed a patent application with the bureau in accordance with the provisions of the patent M330898. However, the above is only the preferred embodiment of the present invention. When it is not possible to limit the scope of the implementation of this creation, that is, the equivalent change and modification of the patent application scope of this creation should still belong to this creation patent. Within the scope of coverage.
