Description

Multi-purpose pump

The present invention relates to a pump, and more specifically to a multi-pass pump.

Press, the conventional pump, especially the manually operated pump, is mainly used to inflate foreign objects (such as tires, balls). However, there are two main types of air pumps that are usually operated by humans. One is a direct air supply type, that is, when the user acts, the gas is directly injected into a foreign object. The person injects the gas in advance and stores it in the gas storage cylinder. When the gas is to be inflated, the gas storage cylinder is used to inflate foreign objects. However, the above two types of air pumps, whether they are direct air supply type or air storage type, have their advantages. For example, the direct air supply type air pump is suitable for foreign objects that require low air pressure (such as low pressure tires), Pneumatic pumps are suitable for foreign objects that require high air pressure (such as high-pressure tires). However, as far as the existing pumps are concerned, the direct-supply type and the gas-storage type pumps not only have different usage methods, but also have completely different structures. Therefore, if the user has two needs, he must purchase them. The two different types of pumps are not only inconvenient in operation and storage, but there are also situations where purchasing two types of pumps results in wasted money.

In view of this, in order to improve the prior art, the conventional pump has a single purpose and cannot be selectively replaced.

The cylinder body 112 is hollow, and is connected to the base 111 with its bottom end upright. The cylinder body 112 has a socket hole 116 on the side adjacent to the bottom end, which connects the interior of the cylinder body 112 to the outside, and the fixed base. 113 is fixedly connected to the outer peripheral surface of the barrel 112, and one side of the fixed base 113 is provided with a receiving groove 117. The fixed top seat 114 is fixed to the top of the barrel 112 and has a coaxial connection to The shaft hole 118 and the second mouth hole 119 inside the barrel 112, the gas injection bottom plug 115 is placed inside the barrel 112, and the piston rod group 12 is partially placed in the barrel seat 11 for Injecting external air into the inside of the barrel base 11, the piston rod set 12 has a piston 121, a piston rod 122, and a grip 123. The piston 121 is placed inside the barrel 112, and the piston rod 122 One end is connected to the piston 121 and passes through the shaft hole 118 of the fixed top seat 114. The grip 123 is connected to the other end of the piston rod 122 and is located in the cylinder. Outer 112, for the user to hold and perform axial linear reciprocating displacement with respect to the cylinder base to inject external air into the cylinder body 112; the check valve 13 is a socket hole with the cylinder base 11 116 is sleeved; one end of the gas pipe 14 is connected to the check valve 13 so that the gas in the cylinder 112 can be transported from the check valve 13 to the gas pipe 14 only in one direction, and cannot be removed from the The gas pipe 14 is reversely transported into the cylinder body 112; the shunt nozzle seat 15 is fixedly connected to the fixed top seat 114 of the cylinder seat 11, and the shunt nozzle seat 15 has an input nozzle 151 and communicates with the input nozzle 151 The second output nozzle 152 is sleeved with the other end of the gas pipe 14, and the second output nozzle 152 passes through the nozzle hole 119 of the fixed top seat 114. Therefore, the above is an introduction to the components of the multi-purpose air pump 100 and its assembly method provided by a preferred embodiment of the present invention, and then its use characteristics are described as follows: First, please refer to FIGS. 3 to 6 As shown, the present invention can be connected to a barometer 20 and an output pipe 30 (as shown in the third and fourth figures), the barometer 20 is connected to one of the output nozzles 152 of the pump body 10 (such as (Shown in the fourth figure), and one end of the output pipe 30 is connected to the other output nozzle 152 of the pump main body 10 (as shown in the fourth figure). As a result, when the user starts to actuate the piston rod set 12 (as shown in the fifth figure), the gas in the barrel 112 is squeezed by the piston 121 and passes through the gas injection bottom plug 115, and then passes through the gas injection bottom plug 115. The check valve 13 and the gas pipe 14 are fed into the input nozzle 151, so that the gas sent into the input nozzle 151 can be diverted through the two output nozzles 152, so that the gas passes through one of the output nozzles 152. The output takes over the output (as shown in the fifth figure) to directly inflate a foreign object (such as a low-pressure tire or a sphere), and the gas returned by the foreign object can enter the air pressure through another output nozzle 152 The gas pressure is measured in Table 20 (as shown in the fifth figure), and the design of the check valve 13 prevents the gas in the gas pipe 14 from being reversely transported into the cylinder 112 ( (As shown in Figure 6). Secondly, the accommodating groove 117 of the pump main body 10 is in communication with the socket hole 116 of the cylinder body 112 and is used for receiving by the check valve 13. In addition, in addition to the above-mentioned modes of use, the present invention can also be connected to an air storage device 40 (such as the seventh to ninth drawings), which has an air storage cylinder 41, a switching valve 42, and a barometer 43 and an output takeover 44 (as shown in the eighth figure). The gas storage cylinder 41 is used for storing gas, the switching valve 42 is in communication with the gas storage cylinder 41 and the two output nozzles 152 of the pump main body 10, the switching valve 42 also has two output channels 421, the barometer 43 and the switching One of the output channels 421 of the valve 42 is in communication, and the output takeover 44 is in communication with the other output channel 421 of the switching valve 42. In this way, when the present invention is in use, the switching valve 42 may be first switched to the gas storage mode, that is, the switching valve 42 and the output connection 44 are closed. As shown in the eighth figure, when the user starts to actuate the piston rod group 12, the gas in the cylinder body 112 will be squeezed by the piston 122 to pass through the gas injection bottom plug 115, and then pass through the check valve 13 The gas pipe 14 is fed into the input nozzle 151, so that the gas sent into the input nozzle 151 can be output through the two output nozzles 152 (or any output nozzle and any output nozzle is closed). Let the gas enter the switching valve 42 through at least one output nozzle 152. Since the output connection 44 and the switching valve 42 are closed at this time, the gas can only enter the pressure gauge 43 and the gas storage tank 41. The gas storage tank 41 is used for gas storage, and the gas pressure gauge 43 is used to measure the gas pressure of the gas stored in the gas storage tank 41 (as shown in the eighth figure). 42 is switched to the inflation mode, so that the output connection 44 and the switching valve 42 are electrically connected at this time. In this way, the gas in the gas cylinder 41 can be output to the output channel 421 of the switching valve 42 to The output takes over 44 (as shown in the ninth figure) to facilitate the inflation of foreign objects (such as high-pressure tires).Therefore, the present invention can be replaced and connected with directly inflated equipment (output takeover) and gas storage equipment, so that the user can make appropriate selection and replacement for different inflatable objects, thereby improving the convenience and versatility of use. . Furthermore, the present invention does not need to purchase two sets of equipment containing a pump main body, and can be replaced by a single pump main body in conjunction with a direct inflation device and a gas storage device, so as to reduce the cost and other effects required by the user. The above disclosure is only the preferred embodiments provided by the present invention, and is not intended to limit the scope of implementation of the present invention. Any equivalent changes made by those skilled in the art in accordance with the present invention should belong to the present invention. Coverage.
