[0003] In addition, during the use of gas purging equipment, traditional gas purging equipment has relatively simple functions, and it is not easy for personnel to monitor the air pressure changes inside the gas purging equipment in real time, resulting in insufficient air pressure inside the gas purging equipment, resulting in poor impurity cleaning effect. In addition, gas purging equipment is usually not environmentally friendly and consumes a lot of electricity during use, which affects the use of gas purging equipment. Then, when the operator is purging the equipment, most of the air pressure can easily cause gas reflux, which can easily cause the gas to carry impurities into the purging equipment, resulting in a shortened service life of the gas purging equipment. Summary of the Invention

In addition, the gas purging device is usually not environmentally friendly and consumes a lot of electricity during use, which affects the use of the gas purging device. Then, when the operator is purging the equipment, most of the air pressure is likely to cause gas reflux, which is likely to cause the gas to carry impurities into the purging device, resulting in a shortened service life of the gas purging device.

[0006] According to the above description, when personnel use a purge bottle to clean foreign matter from an object or pipe, they can place the purge pipe on the surface of the connecting plate. Then, during the operation of the purge bottle, the gas will follow the connecting pipe to lift the blocking ball and the return spring, so that the blocking ball is pushed from one end of the connecting pipe into the interior of the fixed pipe, making it easy to transport the gas out. When part of the gas refluxes, its return spring drives the blocking ball to contract, so that the blocking ball is connected to one end of the connecting pipe, thereby preventing the gas from carrying foreign matter backflow.

[0007] Furthermore, the energy-saving component includes a photovoltaic panel embedded in the surface of the threaded ring, the other side of the photovoltaic panel is electrically connected to a power cord, one end of the power cord is electrically connected to a battery, the other side of the battery is electrically connected to an inverter via a data cable, and the other side of the inverter is electrically connected to the power supply end of the gas increasing pump.

[0008] According to the above description, through the structural design of the energy-saving component, when the operator uses the gas booster pump outdoors, its photovoltaic panel can absorb outdoor solar energy, and then the photovoltaic panel converts the solar energy into electrical energy and transmits it to the inside of the battery. Then the inverter converts the DC power inside the battery into AC power and transmits it to the inside of the gas booster pump, thereby playing a role in energy saving of the gas booster pump.

[0009] On the basis of the above solution, the bottom of the battery is fixedly mounted on the middle of the top surface of the gas increasing pump, and the other side of the inverter is fixedly connected to one side of the surface of the gas increasing pump.

[0011] According to the above description, through the structural setting of the discharge mechanism, when personnel need to discharge the residual gas inside the purge bottle, they can twist the stop cap to separate it from one end of the discharge pipe, so that the gas inside the purge bottle pushes the joint open, causing the spring to extend, and then the gas inside the purge bottle is discharged to the outside along the connecting ring, thereby making it convenient for personnel to discharge the residual gas inside the purge bottle.

[0012] Furthermore, a blocking cover is rotatably connected to the front of the joint, and an inner wall of the blocking cover is threadedly connected to one end of the discharge pipe.

[0013] According to the above description, the setting of the baffle makes it convenient for personnel to open the discharge pipe to discharge the residual gas inside the purge bottle; Based on the above solution, the air pressure detection assembly includes a cavity tube threadedly connected to one end of the detection tube, a floating block is slidably connected to the interior of the cavity tube, and a transparent plate is embedded in the outer surface of the cavity tube.

[0014] According to the above description, through the setting of the air pressure detection component, when the personnel use the purge bottle, the air pressure inside the purge bottle is transmitted to the cavity tube to lift the floating block, making it convenient for the operator to observe the changes in the air pressure inside the purge bottle; As a further solution of the present invention, an injection hole is opened on the top of the cavity tube, and a plug is connected to the internal thread of the injection hole.

[0015] According to the above description, through the setting of the injection hole and the plug, when the personnel need to clean the inside of the cavity tube, the personnel can screw the plug and the cavity tube to replace the floating block inside, thereby facilitating the operator to replace the floating block; Furthermore, a fixed tube is inserted into the top of the connecting tube, a flange is provided on the top of the fixed tube, the diameter of the blocking ball is adapted to the inner diameter of the connecting tube, and the diameter of the blocking ball is smaller than the inner diameter of the fixed tube.

[0016] According to the above description, through the arrangement of the fixed tube and the blocking ball, when a person needs to connect an external pipe, he can use the connecting plate to thread the pipe, and then when the gas is blown from the inside of the purge bottle to the outside, the blocking ball will be pushed into the inside of the fixed tube, thereby facilitating the person to guide the blocking ball; On the basis of the above solution, an anti-oxidation film is attached to the outer surface of the purge bottle to increase the anti-oxidation property, and reinforcement rings are fixedly connected to the surface of the purge bottle at equal intervals.

[0017] According to the above description, by providing the anti-oxidation film and the reinforcement ring, during the use of the purge bottle, the anti-oxidation film increases the anti-oxidation property of the purge bottle, and the reinforcement ring increases the toughness of the purge bottle.

[0018] Furthermore, a sealing ring is fixedly connected to one side of the outer surface of the connecting tube, and a sealing ring is provided on one side of the outer edge of the detection tube.

[0019] According to the above description, the sealing performance of the connecting pipe is increased through the design of the sealing ring.

[0020] Compared with the prior art, the present invention provides a gas purge device with an exhaust function, which has the following beneficial effects: The present invention arranges a connecting tube, a connecting ring, a return spring and a blocking ball. When an operator needs to perform a purging operation on an external device or pipeline, the gas and liquid inside the purging bottle push up the return spring and the blocking ball along the connecting tube, so that the gas pressure is delivered to the inside of the fixed tube. Subsequently, when gas refluxes inside the fixed tube, the return spring drives the blocking ball to contract, so that the blocking ball is snapped into one end of the connecting tube, thereby preventing the gas reflux from carrying foreign matter.

[0021] The present invention uses energy-saving components and an air pressure increasing pump in coordination with each other. When an operator uses a purge bottle outdoors, the photovoltaic panel can absorb outdoor solar energy and convert it into direct current and transmit it to the inside of the battery. Then the inverter converts the direct current inside the battery into alternating current and transmits it to the inside of the gas increasing pump, thereby achieving energy saving and environmental protection.

[0022] 3. The present invention cooperates with the discharge mechanism and the purge bottle. When the operator needs to discharge the residual gas inside the purge bottle, the operator can twist the stop cap to separate one end of the discharge pipe. Then the resistance spring purges the gas inside the bottle to push up the joint, allowing the resistance spring to extend, making it convenient for the operator to discharge the residual gas inside the purge bottle.

[0023] 4. The present invention uses the air pressure detection component and the purge bottle in coordination with each other. When the operator uses the purge bottle, the gas inside the purge bottle is transported along the detection tube to the inside of the cavity tube, so that the air pressure lifts the floating block inside the cavity tube. The operator can then observe the floating block to predict the change of air pressure inside the purge bottle. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] See also Figures 1-6 As shown; In order to facilitate the operator to observe the changes in the internal air pressure of the purge bottle 1, in the present invention, a circular hole is opened on the other side of the top surface of the top cover 2, and a detection tube 15 is inserted into the inside of the circular hole.

During the use of the gas increasing pump 11 outdoors in the backyard, the photovoltaic panel 81 can absorb solar energy and convert the solar energy into electrical energy inside the photovoltaic panel 81, and transmit the DC power to the inside of the battery 82. Then the inverter 83 can convert the DC power inside the battery 82 into AC power and transmit it to the inside of the gas increasing pump 11, thereby achieving the effect of energy saving and environmental protection.
