Description

Technical Field

[0001] This utility model belongs to the technical field of air inflation tools, and more specifically, it relates to a pressure-displaying plastic air pump. Background Technology

[0002] An air pump is a tool used to inflate objects. Common uses include inflating tires, air cushions, sporting goods (such as soccer balls and basketballs), balloons, etc. It typically consists of a cylinder, piston, nozzle, and handle, and uses manual or electric methods to generate pressure, forcing air into the target object.

[0003] Based on the above, the inventors have discovered the following problems: In the use of existing air pumps, the pointer pressure gauge on most air pumps is not convenient for people to read the pressure data, and the pressure gauge is equipped with a battery. When the battery power is low, it needs to be replaced. Frequent battery replacement is cumbersome and inconvenient to use, which reduces the user experience.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a pressure-display plastic air pump in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose and function of this pressure-display plastic air pump are achieved by the following specific technical means:

[0006] A pressure-display plastic air pump includes an air pump body and a high-pressure pack. The high-pressure pack is mounted on the air pump body and has a digital pressure gauge with a display screen. A charging slot is located on one side of the digital pressure gauge, and a charging interface is located inside the charging slot. A sealing plug is movably installed inside the charging slot. An air tube is mounted on the air pump body, and a handle is mounted on the piston at the top of the cylinder of the air pump body.

[0007] Furthermore, a connector is installed on one inner end of the sealing plug, and a ball plug is provided at the top of the connector. A slot matching the connector is provided on one side of the charging slot, and the connector is embedded and connected to the slot.

[0008] Furthermore, a protrusion is installed on one side of the sealing plug, and a groove matching the protrusion is provided on one side of the charging slot, with the protrusion engaging with the groove.

[0009] Furthermore, the sealing plug, protrusion, and connector are all made of rubber.

[0010] Furthermore, a rechargeable battery pack is installed in the base of the digital pressure gauge, and a pressure sensor is installed in the high-pressure pack. The digital pressure gauge is electrically connected to the pressure sensor in the high-pressure pack.

[0011] Furthermore, a retaining seat is installed on one side of the cylinder on the air cylinder body, and a limiting groove is provided on one side of the retaining seat, and the air pipe is engaged and connected with the retaining seat.

[0012] Furthermore, an air nozzle is installed at the top of the air tube, a storage tube is installed on the air cylinder body, and a top cover is screwed onto the top of the storage tube.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] By using a digital pressure gauge, data can be read directly from the display screen, making the data display more intuitive, increasing the speed of reading pressure data, and improving the user experience.

[0015] By prying out the sealing plug, the protrusion detaches from the groove. At this point, the charger's data cable can be connected to the charging interface to charge the rechargeable battery inside the digital pressure gauge, ensuring that the digital pressure gauge has sufficient power. The connector slides into the slot, allowing the sealing plug to hang on the charging slot, preventing the sealing plug from being lost and improving practicality.

[0016] The use of rechargeable battery packs makes it easier for people to charge digital pressure gauges, avoiding frequent battery replacements and improving practicality. Attached Figure Description

[0025] Example:

[0026] As attached Figure 1 To be continued Figure 3 As shown:

[0027] This utility model provides a pressure display plastic air pump, including an air pump body 1 and a high-pressure pack 2. The high-pressure pack 2 is mounted on the air pump body 1 and is equipped with a digital pressure gauge 8. The digital pressure gauge 8 has a display screen and a charging slot 4 on one side. A charging interface 14 is provided inside the charging slot 4, and a sealing plug 5 is movably installed inside the charging slot 4. The air pump body 1 is equipped with an air pipe 3, and a handle 6 is mounted on the piston at the top of the cylinder of the air pump body 1. By using the digital pressure gauge 8, data can be directly read from the display screen, making the data display more intuitive, improving the speed of reading pressure data, and enhancing the user experience.

[0028] The sealing plug 5 has a connector 16 installed on one inner end, and the top of the connector 16 is provided with a ball plug. The charging slot 4 has a slot 15 that matches the connector 16 on one side, and the connector 16 is embedded in the slot 15.

[0029] The sealing plug 5 has a protrusion 12 installed on one side, and the charging slot 4 has a groove 13 that matches the protrusion 12 on one side. The protrusion 12 and the groove 13 are engaged and connected.

[0030] The sealing plug 5, the protrusion 12, and the connector 16 are all made of rubber. By prying the sealing plug 5 outward, the protrusion 12 disengages from the groove 13. At this time, the data cable of the charger can be connected to the charging interface 14 to charge the rechargeable battery block inside the digital pressure gauge 8, ensuring that the digital pressure gauge 8 has sufficient power. The connector 16 is slidably connected to the slot 15, so that the sealing plug 5 is hung on the charging slot 4, which can prevent the sealing plug 5 from being lost and improve its practicality.

[0031] The digital pressure gauge 8 has a rechargeable battery pack inside its base, and the high-pressure pack 2 has a pressure sensor inside. The digital pressure gauge 8 is electrically connected to the pressure sensor inside the high-pressure pack 2. The use of the rechargeable battery pack makes it easy for people to charge the digital pressure gauge 8, avoids frequent battery replacements, and improves its practicality.

[0032] The cylinder body 1 is equipped with a retainer 9 on one side of the cylinder. The retainer 9 has a limiting groove on one side. The air pipe 3 is engaged with the retainer 9. After the air is pumped, the air pipe 3 is engaged with the retainer 9 to prevent the air pipe 3 from tilting and becoming messy.

[0033] The air tube 3 is equipped with an air nozzle 7 at its top end, and a storage tube 10 is installed on the air cylinder body 1. A top cover 11 is screwed onto the top end of the storage tube 10. By rotating the top cover 11, replacement parts or air needles can be taken out from the storage tube 10, which improves practicality.

[0034] The specific usage and function of this embodiment are as follows:

[0035] First, check the integrity of the device. Only use it after confirming it is intact. When using it, first align the air nozzle 7 with the inflation port and connect it. Press the handle 6; the piston moves inside the cylinder, generating negative and positive pressure. The pressure sensor inside the high-pressure pack 2 transmits data signals to the digital pressure gauge 8, which is then displayed on the screen, allowing users to read the pressure data in real time and easily control the tire pressure. Simultaneously, if the digital pressure gauge 8 is low on power, pry out the sealing plug 5, and the protrusion 12 disengages from the groove 13. At this time, connect the charger's data cable to the charging interface 14 to charge the rechargeable battery inside the digital pressure gauge 8, ensuring sufficient power. The rechargeable battery allows for easy charging of the digital pressure gauge 8, avoiding frequent battery replacements. The connector 16 slides into the slot 15, allowing the sealing plug 5 to hang on the charging slot 4, preventing its loss. Rotating the top cover 11 allows replacement parts or air needles to be removed from the storage cylinder 10, improving practicality. This device has a novel overall design and simple structure, making it worthy of widespread promotion and use.
