New description: [New technical field] The present invention relates to an air intake device, which is specially designed into the motor room of a pneumatic tool, and can be used for air intake devices of two or two kinds of pneumatic tools for supplying gas to lubrication parts. . The lubricating oil is pneumatically [previously]: it is designed to use gas to drive the rotation, and then indirectly by the motor and ^.^ m 颂 slave to work, the gas == The air intake device is enclosed in the motor block of the Bayi. However, the traditional pneumatic two-connector motor can be used to drive the motor to rotate. However, since the general pneumatic tools need to rotate a lot of parts, the conventional pneumatic tools can only feed the gas but cannot produce the lubricating effect. Parts are prone to wear in the absence of lubrication and have a short service life. In order to improve the above missing, some pneumatic tools add a lubricating oil supply device to the air intake device. During the gas entering process, the lubricating oil is continuously sent to the pneumatic tool to lubricate the parts of the pneumatic tool. It is known that a pneumatic tool with lubrication can not only improve the problem of rapid wear of the parts, but also utilize the lubricating oil to carry out the generated debris, but the known lubricating oil supply equipment is continuously supplemented with the gas source. In the use, it is easy to produce the problem of excessive addition of lubricating oil. When the lubricating oil, ', the power is too late, not only waste, the use cost is high, too much lubricating oil may also ooze the contaminated processed parts, resulting in inconvenience in cleaning. . [New content] The purpose of this new type is to provide an air intake device that can deliver lubricating oil in a batch mode of 3 M398472, and thus achieve the effect of improving fuel consumption and improving the service life and output efficiency of the parts. The air intake device of the present invention can introduce a gas into a motor seat of a pneumatic tool, and comprises: a housing having an oil storage space, a partitioning mechanism defined in the oil storage space and defining an air inlet passage: An oil control unit mounted on the weir separating mechanism, the housing further having at least one air guiding hole communicating with the air inlet passage, and the air inlet passage has a mixing portion, the partitioning mechanism further having a communication portion and a storage portion The oil space has a valve port oil control passage and a fuel supply passage communicating with the oil control passage, and the oil control unit includes an oil control member that movably closes the valve port of the oil control passage. When the gas enters the mixing section, the generated suction will suck the oil control member toward the valve port and close the valve port, and when the gas delivery speed decreases, the pressure in the intake passage increases, the oil control member will be switched from a closed position. At a retreat position, at this time, the lubricating oil located in the oil storage space can flow from the replenishing passage to the valve port of the oil control passage, waiting for the gas to be sent to the motor seat at the next intake. The beneficial effect of the novel is that since the lubricating oil is sent out in a batch manner in each intake, the air intake device of the present invention is not only innovative but also improves the service life of the parts in the case of fuel economy. And output efficiency. The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments. 4 M398472 ′′: 2, 3, the present air intake device 较佳 较佳 - preferred embodiment = ° 1 - the motor base 11 is connected, and provides the gas required for the completion of the motor seat η, in this embodiment The air intake device iq is connected by a screw (four) cymbal type and a motor base ' 1 but the air intake device H can also be connected by a pipe and a motor base η 'Because the gas is used to drive the pneumatic work and 1 work 'And how the air intake device 1G is connected to the motor base n is not the focus of this new improvement and will not be described.

On the P 231 is a partition 32, and an intake pipe 33 which is hollow and is disposed between the mixing seat 31 and the partition 32. The mixing seat 31, the intake pipe 33 and the partition 32 are used for the oil storage. An air intake passage 30 is partitioned from the inner portion of the space 21. The mixing seat 31 is disposed around the axis and has a fixing ring wall 311 which is airtightly abutted between the first ring faces 221 of the housing 2, and a mounting ring wall 312 for the intake pipe 33 to be erected. And the intake passage 30 has a mixing portion 3〇 corresponding to the mixing seat 31, a communicating portion 302 corresponding to the intake pipe 33, and an engaging portion 303 corresponding to the partitioning seat 32, the engaging portion 303 It is tapered and engages with the air guiding hole 232 of the air intake stud 23 . Referring to Figures 1, 5 and 6, the mounting ring wall 312 has an oil inlet end face 314 facing the oil reservoir space 21, an oil outlet end face 315 facing the mixing portion 3 〇1 and having a ring-shaped shape, one through which The oil inlet end surface 314 and the oil control passage 34 of the oil discharge end surface 315, a refueling passage 35 perpendicular to the oil control passage 34 and communicating with the oil control passage 34 and the oil storage space 21, and a connecting end face 314 and an oil end face Pressure relief 36 of 315. The oil control passage 34 has a first screw portion 341 adjacent to the oil inlet end surface 314, a valve port 342 which is located on the oil discharge end surface 315 and has a reduced aperture, and a gap between the screw portion 341 and the valve port 342. And the oil replenishing section 343 of the oil passage 35 should be replenished. The pressure relief passage 36 has a second screwing portion 361 adjacent to the oil inlet end face 314, an exhaust port 362 located at the oil outlet end face 315, and a pressure relief port 363 therebetween. 6 The oil control member 4 of the oil control unit 4 of the embodiment 342 is mounted on the stroke control member 42 of the first screw connection 4 341 of the oil control passage 34 from a valve adjacent to the oil control passage 34, ', A - ^ ^ ^ -V In the present embodiment, the oil control member 41 is in the form of a steel ball, and the stroke _# 4 can be adjusted according to the form of the screwed ...", and the ice degree of the W is adjusted to Oil control stroke. The pressure relief unit 5 &&&&& 5 of the present embodiment includes a plurality of pressure relief adjusting members 51 mounted on the second screwing portion 3 61 of the mixing seat 31 A leakage preventing ring 52 at the secret opening 363 of the pressure relief passage 36, a steel ball form (four) pressing member μ', and a spring 54 for pressing the pressure detecting member 53 against the leakage preventing ring 52. The switch 5 of the p-palladium example includes an opening _ 6-shapedly extending through the inlet pipe 33 and rotatably sleeved on the periphery of the inlet pillar 23 of the casing 2 The intake valve sleeve 62, the linkage pin 63 radially inserted into the switch chamber 61 and controlled by the intake valve sleeve 62 to be movable in the ring groove 233 of the housing 2〇, and a non-moving The switch plate 64 is assembled on the first ring-shaped surface portion 221 (see FIG. 3) of the housing 20. The switch 61 has a movable switch plate 61A that is attached to the fixed switch plate 64. The movable switch plate 611 has two movable control holes 612 adjacent to the edge, and the fixed switch plate 64 has two fixed control holes 641. . When the intake valve sleeve 62 is rotated and the switching valve 61 is rotated, the movable control hole 612 can be driven to be aligned with the fixed control hole 641 ' or the fixed control hole 641, so that the door can be opened. Or turn off the gas flow conduit. Referring to Figures 4, 5 and 7, the air intake device 1 of the present embodiment is clamped to a non-intake position shown by the solid line in Figure 5, due to the air pressure of the mixing portion 301 and the oil pressure in the space 21 of the oil storage M398472. The isostatic state, in addition to the viscosity of the lubricating oil, causes the lubricating oil to adhere to the vicinity of the valve port 342 and does not flow to the mixing portion 301. When the operator rotates the switching valve 61 by the switch unit 6, and the movable control hole 612 of the switching valve 61 corresponds to the fixed control hole 641 of the fixed switch plate 64, the gas can enter the air guiding hole 232 of the housing 20 from the air inlet 28, Then, through the intake passage 30', the corresponding movable control hole 612 and the fixed control hole 641 enter the motor base 11 of the pneumatic tool 1. During the passage of the gas through the merging portion 301 and through the movable control hole 612, 'the lubricating oil originally attached to the valve opening 342 according to the Bernoulli's law' will be squeezed into the mixing portion by the oil control member 41 due to the increase of the fluid velocity.丨, that is, it is brought to the motor seat n by the gas for lubrication. At the same time, the momentum of the gas will also suck the oil control member 41 toward the valve port 342, and thus close the valve port 342, that is, the air intake device will be switched from the non-intake position of the solid line of FIG. 5 to the imaginary line. An air intake closed oil position. That is, in the present embodiment, the intake of the lubricating oil can be automatically blocked by the momentum of the gas during the intake, so that the lubricating oil is supplied in a minute intermittent manner.曰 (4); ε law' The higher the flow rate of the fluid, the lower the M-force, and the lower the pressure, the lower the fluid will increase. Therefore, in the intake device 1G of the present embodiment, when the supply of the gas is stopped, the pressure is increased in the mixing portion 3G1 due to the decrease in the body speed. At this time, the valve member 42 is originally sealed, and the pressure of the mixing portion 3G1 is suddenly increased. And the control of the stroke; the direction of the piece 42 retreats, the ancient connection # & door + while retreating, the lubricating oil located in the refueling passage 35 will flow in the direction of the valve port 342 • ^ 2, and again by the figure 7 The retracted position is restored to Figure 5. Caution Record # - t ' The non-intake position of the line is not. That is, the control * 8 waits for the next time the oil to be controlled 41 and the valve port 342 are filled with lubricating oil, and the piece 41 is extruded. change. The supply of the new type of lubricating oil is to use the change of the gas to achieve the purpose of the micro-intermittent oil supply, and the outflow amount of the lubricating oil is also related to the retreating stroke of the oil control member 41. 'The larger the retreating stroke of the oil control member 4! 'The more the amount of single oil is '', the change of the single oil amount of the lubricating oil. In this embodiment, the screwing depth of the stroke control member 42 can be rotated, and the adjustment method can disassemble the air intake device. i 1G, a square can also be placed on the housing 2 (), the tool extends into the perforation of the rotation control member 42, which is not illustrated here. When the lubricating oil reserve in the oil storage space 21 is lowered, the oil sliding oil can be injected into the oil storage space 21 by screwing the oil slinger $29', so the present yoke example is convenient in supplying the lubricating oil. The amount of lubricant delivered can be adjusted according to the needs of lubrication. Referring to Figures 4 and 6, in the embodiment, the pressure relief unit 5 is further mounted on the mixing base 31. The upper material pressure unit 5 can allow gas to flow to the oil storage space when the pressure inside the air inlet passage 30 is excessive. The direction of 21 is relieved. That is, when the pressure in the port 301 is too large, the gas will enter the Maoqiang Road 36' through the exhaust port 362 and push the pressure relief member against the elastic force of the spring 54 to retreat to the oil body. The space 21' thereby prevents the oil control member 41 from retreating when the pressure inside the intake passage 3 is excessive. The above five children can clearly know that the air intake device of the pneumatic tool is the same. The innovation can also be used to automatically and intermittently supply a small amount of lubricating oil (4) while the gas passes through the air intake device 1G. The above-mentioned lubricating oil supply method can not only lubricate the parts of the pneumatic worker #1, but also extend the use of the parts. The life, since the parts are well lubricated, can also increase the output efficiency of the gas and the tool 1. In addition, since the present invention is supplied in a minute amount in the supply of lubricating oil, the present invention also has the effect of fuel economy and cost. That is, the design of the air intake device 1G of the present invention can indeed achieve the effects of prolonging the service life of the pneumatic tool and improving the output efficiency in the case of fuel economy and lubrication. However, the above description is only a preferred embodiment of the present invention, and the scope of the present invention is limited by this, that is, the simple equivalent change of the patent application scope and the new description content of the present invention is Modifications are still within the scope of this new patent. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of a preferred embodiment of the present novel air intake device.
