Description

V. Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a pump, especially a pump with a pumping and inspiring effect. [Prior technology] _ With the development and progress of science, people's requirements for things It has also become quite delicate and demanding from the old thinking of "use it." Only in the concept of continuous progress or innovation 'generate new forms to increase the added value of products and effectively reduce costs' can they compete in the market. Survive under a fierce test. Referring to Annex I, US Patent No. 6422 832, for the cylinder π, it is provided with an air outlet pipe 23, an air suction pipe 24, and a base 21 connected to the air outlet pipe 23 and the lice officer 24, a control Piece 4〇 is pivoted on the base 21. By turning the control member 4J), the hose 50 can be selectively connected to the air outlet pipe 23 or the air suction pipe 24, so that the air pump has the functions of inflating and inhaling. However, the arrangement of the air outlet pipe 23 and the air suction pipe 24 increases the volume of the air pump ', and both of the air outlet pipe 23 and the air suction pipe 24 need to be provided with a check valve, which greatly increases the production cost. It is not practical to use the left and right pivots of the control member 40 to change the pumping or inspirating effect of the pump, because the left and right pivots of the control member 40 will affect the placement position of the pump 3 and the control member 40 and the base. There is no positioning structure between the seats 21, and the control member 40 cannot be positioned accurately. It is important that this type of structure is not suitable for a portable mini-pump because the volume of the pump is too large. The lack of all these conventional pumps is necessary for research and development. Therefore, the present invention intends to eliminate or at least alleviate the problems encountered in the prior art 0 591172

[Summary of the Invention] The technical problem to be solved by the "pump with pumping and inspirating effect" of the present invention is that although the conventional pump has the function of pumping and inspirating, the settings of the exhaust pipe and the inspiratory officer are increased. The volume of the pump greatly increases the cost of production and production, and is not suitable for portable mini pumps. The left and right pivots of the control member can change the pumping or inspirating effect of the pump, which will not only affect the placement position of the pump, but also does not have a positioning mechanism between the control member and the base, and the control member cannot be positioned accurately. v The present invention provides an air pump with air pumping and air suction function. One end of a cylinder is provided with an air suction channel and an air outlet, and a filling member pivoted on the cylinder is provided with two holes corresponding to the air channel. One hole is connected to the filling device and the other is connected to the outside world. The cylinder (filling part) can be rotated between the first position and the second position, so that the hole communicating with the filling device can selectively correspond to the suction channel or the outlet channel, so that the pump can be pumped or pumped. Gas operation. And a positioning device is arranged between the steam rainbow and the filling device, so that when the cylinder (filling part) rotates between the first position and the second position, the positioning device can accurately position the cylinder in the filling > filling structure design Reliable and practical. Other objects, advantages, and novel features of the present invention will become more apparent from the following detailed description and related drawings.

Description of the invention (5) B, tLt chart 'shows #user pushes the reciprocating member 20 fi to the cylinder _: Zeng 1; the piston 22 on the meat will push the gas in the space 11 so that The gas is pushed out: "The one-way valve i 21 and the gas are discharged to the outside through the filling member 30. This repeated operation can quickly remove the gas in the to-be-inhaled object 50. Figure JA and Figure 9B The second embodiment of the present invention is shown < column. The second embodiment is the same 'except for the addition of-connected to the second brother-space 16 in the cylinder 10, the second space 16 is provided-connected to the space 11: A one-way valve 111 is provided at the end of the workshop 11 less than the hole 17, and the gas in the room 11 is returned to the second space 16. The piston 22 is changed to the early-direction piston 24, which is one-way The piston 24 is a known technique, and it is no longer appreciated here. * In the preferred embodiment, the cylinder is composed of a single component. As shown in the tenth figure of FIG. 2, when the pump 1 is in the suction state, the cylinder 10 ^ & One position. When the user connects the to-be-inspired object 50 to the air pump 1, the air in the 50 will flow into the second space 16 of the cylinder 10 when used. When the reciprocating member 20 is moved in the cylinder 10, the gas in the second space 16 pushes the one-way valve 111 of the sweat knife and enters the space 11 of the cylinder 10. 1. According to the eleventh figure, the display space The gas in 11 is returned by the check valve to the second space 16. 'Pulling the reciprocating member 20 of the pump i toward 10 = 10' can force the other end of the gas flow at the rear end of the piston 24 'because the piston 24 It is a one-way piston. Figure 12 shows that when the user pushes back and forth $ into the cylinder 10 again, the piston 24 on the piston rod 21 will push the gas in the space 11 so that = push out the air channel 1 2 Inside the check valve i 2! And the gas is discharged through the filling member 30, and the gas in the second space 16 will push open the check valve in the space 丨 丨

If the user wants to use the air pump to inhale, he can rotate the cylinder 10 so that the filling device 32 in the filling member 30 is relatively located on the side of the air outlet 12 of the cylinder 10. Referring to the thirteenth figure, the air pump 1 is shown at In the pumping state, the cylinder is located in the first position. Since there is no one-way valve in the suction channel 13, outside air can flow into the second space 16. When the user pushes the reciprocating member 20 into the cylinder 丨 0, the gas in the second space 16 will push open the check valve 丨 丨 1 in the space 丨 丨 and enter the space 11 of the cylinder 10. Referring to the fourteenth figure, the gas in the display space is blocked by the check valve η and cannot flow back into the second space 16, and the reciprocating member 20 of the pump 1 is pulled out of the steam rainbow 10 to force it. The gas at the rear end of the piston 24 flows to the front end of the piston 24 because the piston 24 is a one-way piston. Referring to the fifteenth figure, it is shown that when the user pushes the reciprocating member 20 into the cylinder again, the piston 24 on the piston rod 21 will push the gas in the space 11 to push the gas out of the one-way in the air channel 12 Valve 2 1 enters the filling device 32 of the filling member 30, and further pushes gas into the to-be-inflated material 40. By repeating this operation, the gas can be quickly injected into the to-be-inflated material 40. Figures 16A and 16b show a third embodiment of the present invention. The second embodiment is the same as the second embodiment, except that the cylinder 10 is changed to a two-tube structure, so that a tube-in-tube type is formed. Figures 17 and 18 show a fourth embodiment of the present invention. The fourth embodiment is the same as the second embodiment, except that the filling member 30 and the filling device 32 'are changed in shape. The filling piece 30 is implemented as a base and can be placed on
