New Description: 【New Technology Fields】 This creation department has an improvement on the observation of dry grabs, especially the compressed air jets that are dry and smashed, and the siphon flow is large, effectively reducing the consumption of compressed air. The amount of gas relatively reduces the wear and tear of the electric energy, and the smooth flow of the mouth reduces the noise value. [Prior Art] "Eight", 钇 主要 is mainly used in the drying operation of water-soluble paint spray paint, as shown in Figure 8 'The bulletin number No. 574, the dry robbing, its main features are: The head 11 of the body 1 has a channel 111 and a plenum 112', and the channel η is connected to the plenum 112 and forms a combination of taper: 114'. An end that is coupled to the head of the body has a sinus end 24, and the abutting end 24 has a taper that cooperates with the joint 114 of the passage (1) in the head u, and is forced against the end The plurality of venting grooves are provided at the end of the hybrid port and are spaced apart by the f-end 24 to form a plurality of gaps between the wire end 24 of the inlet gas 2 and the head: 11: combination of the σ 114 for the gas chamber. (1), == two to the passage 111, and the inlet gas 2 has a through-opening air passage 26, the end portion being in communication with the passage (1) of the head portion 11, the air passage 26 being relatively connected to the other end of the passage ill, into 』, please refer to Figure 9::: Entering the factory 61, ^^ (two) Jin not 'The drying of the compressed gas is from the venting groove 25 30 degrees straight direct "slaves Inside, and the money is low pressure, the airflow to the outside of the cover 3 is in the inner level of the channel m, so that the outside of the cover 3 is empty, and the oxygen is discharged from the air outlet 115. M315609 paint collision produces the effect of drying, so it has the following disadvantages in use: 1. Compressed gas is directly sprayed into the human channel (1) by the venting groove 25 at a angle of 3G, which will cause collision with each other and then to the channel Diffusion around the inner wall will produce a large noise value. 2. The inlet gas 2 is provided with abutment (4), and the gap between the abutment end 24 and the joint passage 114 of the head passage 11 has a plurality of gaps, and the gap is like a plurality of nozzles, so that the compressed air is sprayed by the plurality of gaps to The mixing in the gas chamber 112 will cause turbulence in the gas chamber 112, causing the jet flow to be unstable, which not only increases the noise value (the decibel count is 1.5 db from the drying grab and 1.5M), and The siphon effect is reduced and the amount of air that is ejected from the spray is thus reduced. 3. The compressed gas is directly fed into the channel (1)β from the venting groove 25. The compressed air per minute consumes a considerable amount of gas, and the operating pressure of the air pressure increases, increasing the energy consumption. [New content] The use of siphon-type paint drying and drying, due to the direct injection of compressed air, the low-pressure siphon effect and the nozzle with a few gaps between the joints, resulting in large gas consumption, unstable jet flow and high noise. . The body of the drying gun of the present invention has a siphon cavity and an integrally formed grip at the bottom, and a diffuser is accommodated in the front end of the siphon cavity, and a plug is accommodated in the end hole of the other end, before the plug An exhaust gap is formed between the end face and the inner end of the rear end hole of the body, and a screw hole is formed in the end of the rear end hole for screwing into the rear cover. A curved guide M315609 is arranged between the inner end surface of the rear end hole and the exhaust hole, and the air inlet and the rear end hole are penetrated, and the inside of the plug is arranged to pass through the scale hole. a tapered hole and a rear tapered hole, the secret hole is a tapered hole gradually expanding from the inside to the outside and corresponding to the curved fluid guiding body, the rear end of the rear cover is provided with a mesh and is fixed by a soft plug, the grip Screw the bottom of the valve into a gas valve. : The starting point of the arc material is the starting point of Sl, and the height of the starting point & the height of the starting point & the compressed air will be received by the arc of the lower height. Guide (4) Steerly turn to minus (4), accelerate the jet flow by the shape of the hemp-shaped fluid guide _ and the narrow exhaust gap, causing a lower pressure siphon effect at the corner of the jet flow, and the external suction air will Increased, the air consumption of compressed air will be reduced, Wei Society's consumption of mechanical damage is reduced, and the value of the bathing sound of Pinghuan will be effectively reduced. [Embodiment] First, as shown in Figures 1 and 2, the creation drying (2) mainly includes: a body 1 having a siphon cavity 10 and a bottom portion of the siphon cavity 1 The grip 14, the inside of the siphon cavity 1 is a hollow exhaust hole n, the inner front end is provided with a front end hole 12, and the inner rear end is provided with an internal thread at the end of the end hole 13: 丨31, the rear end hole An arc-shaped fluid guide is disposed between the end end 132 and the venting opening 11: 110. The integrally formed grip 14 is provided with an air inlet hole 15 and penetrates with the rear end hole 13 through which the grip 14 is advanced. A gas valve 70 is screwed to the bottom of the air hole 15. A plug 20 is placed in the end hole 13 of the siphon cavity 1 ,, and a gap gap between the front end surface 21 and the inner end end 132 is formed (the gap between the front end surface and the inner end end 132) (about 〇·〇ι~〇·咖) The plug 20 is provided with a ring groove 22 for a 0-ring 23 to be placed. The plug 2 〇 M315609 is internally provided with a through hole corresponding to the front tapered hole 241 and the rear tapered hole 242. The front tapered hole 241 is inside. The taper hole gradually enlarged outward has a short stroke distance and corresponds to the orphaned guide fluid 110, and the stroke distance of the rear taper hole 242 is long; a rear cymbal 30' is provided with a threaded portion 31 and screwed into it The rear end of the siphon cavity 1 并 is fixed to the plug 2G, the rear cover 3Q is provided with a through-hole cone hole %, and a rear end of the rear cover 3 is provided with a receiving hole 33; a filter screen 40 is sleeved The soft cover 60' is sleeved in the receiving hole 33 at the rear end of the rear cover 3 and fixes the filter screen 40. The soft plug 60 is provided with an inner taper hole. And a diffusion 50 having a diffusion taper hole 51 gradually expanding outward from the inside thereof, wherein the 50-end fitting shaft 52 of the diffuser is provided with a ring groove 53 for accommodating a ring type. The fitting The fine core of the 〇 54 is tightly nested in the receiving hole 12 of the front end of the siphon chamber 1; - as shown in Figures 2 and 3, when the back cover 3G is screwed to the rear end of the siphon chamber (4), the plug The front end shaft 2{)1 of the 2G and the end hole 13 of the siphon cavity 1〇 form a gas chamber 13〇' such that the compressed air input by the air inlet hole 15 can fill the entire annular gas chamber 130; the plug 20 The gap between the front end face 21 and the inner end end 132 of the rear end hole 13 is kept narrow (a gap of about Q. G1 to G. () «, so that compressed air flows into the interior of the siphon cavity 10. Referring to Fig. 3, when compressed air is introduced into the air chamber (10) from the air inlet hole 15, the compressed air will surround the shape of the air chamber (10) and fill the entire interior of the air chamber 130. Inside the siphon cavity w, please refer to the figure of M315609. 4 The height of the starting point of the arc fluid (10) can be lower than the starting point of the chamfer of the front taper hole 241. The height Hz of the point & the height of the aforementioned m, H2 is measured by the starting point of the exhaust _ c, and the height of the two is very small, the financial line enters the audience _: c The raft is first guided by the arc-shaped guide fluid 110 of the height = and is turned into the vent hole u along the solitude. However, if the chamfer formed by the front taper hole suddenly loses its solid body, it will not guide the air flow direction. The role of 'the compressed air will not flow backwards, so that the compressed air is completely jetted in the direction of the lower arc-shaped fluid guide 11 。. See Figures 3, 4, 5*, due to the exhaust gap The area of c is reduced. According to the principle of flow, when compressed air flows into the exhaust gap c from the air chamber 13〇, the flow rate of the compressed air will be accelerated, and the fluid of the hollow ring will flow, and the fluid will flow along the curved guide. The venting direction of the venting hole 11 is applied to the close hole n of the near hole. Since the flow velocity of the compressed air at the curved guiding fluid m is accelerated, it is known from the cyber effort theorem that a low pressure will be generated at the exit of the flow, in front of the cone The low enthalpy formed at the hole 241 will cause a siphon effect on the working gas outside the rear cover 4, and the external zero pressure (gauge pressure) will be guided by the rear cover 30 into the interior and enter the venting hole n to be mixed with the compressed air. Diffusion is mixed and ejected from the outer end of the diffuser 50. As shown in Figures 6 and 7, the diffuser 50 is of a movable type and can be replaced at the same time. The Q-ring 52 of the diffusion H 50 is rubber-fired, and the resistance is large. When the 50 sets of Zhengyi are set in the front hole 12 of the red suction chamber, the frictional resistance can make the diffuser 50 and the siphon cavity 1〇 tightly fit and not easy to loose, so that the dry knowledge is known !! 5 () will not have the lion's worries, so you can replace the different types of 9 M315609 雠 l § 50, with the need to change the different blowing angle or the blowing area of the diffuser 50 as the working environment, which is conducive to the convenience of drying operations Sex. Please refer to the figures 1 and 2, the filter 4 is placed behind the back cover 3〇, that is, after the drying of the gun body, which has the function of cleaning and disassembling, and the net 30 must be brushed frequently. In addition to the surface, to avoid blocking the circulation of air, it is very easy to clean and maintain the net at the rear, and it is convenient to replace or clean the net 30 by simply removing the soft plug (9). The soft plug 60 described above is made of soft rubber, dream gel or na..., and the soft plug 6软 made of soft material is very easy to be placed on the back cover 3〇 or disassembled* The soft material has the property of being deformable, and the property is suitable for disassembly or disassembly, and is not easy to loose. Since the contraction of the working fluid follows the direction of the curved guide fluid 11Q to the venting opening 11, the compression line is very expensive (as shown in Fig. 5), and the noise value (the noise measured at the discharge port L 5M) The value is _, which is lower than the conventional one, and the siphon force is stronger than the conventional one. The ratio of the mouth of the compressed air to the outside air of the siphon is up to, and the ratio of the ratio of the lighter is 1. The ratio of the suction is increased, and the compression is relatively reduced. The air consumption of air, the number of starts of air compressors, and the loss of electric energy consumption are relatively low, which is practical and progressive.铋 所述 ' 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 藉 藉 藉 藉 藉 藉 藉 藉 藉 藉 藉 藉 藉 藉 藉 藉 藉 藉 藉 藉 藉 藉 藉 藉 藉 藉 藉 藉 藉 藉 藉 藉The consumption of the Wei line and the loss of energy 'deep and secretive' have already met the side regulations of the new patent law, and abandoned M315609 to apply for a patent according to law.
