Description

Technical Field

[0001] This invention relates to an apparatus for inflating pneumatic tires, and more particularly to a floor-standing air pump that can house the pressure gauge of the air pump. Background Technology

[0002] Floor pumps are placed on the ground for use and can provide a larger volume of air for bicycle tires. These pumps are equipped with a pressure gauge, allowing the user to know the inflation pressure.

[0003] However, the pressure gauge of existing floor-standing air pumps is a fixed component that protrudes from the front of the air pump, resulting in a large air pump volume, which is not conducive to packaging and transportation.

[0004] Taiwan's utility model patent M634040, "Floor-standing Air Pump," provides an air pump that reduces its volume during packaging and transportation. The pump includes a filling device and a foot. The filling device comprises a pump, a base, and a pressure gauge. The pump extends vertically, and the base is connected to the lower edge of the pump along its vertical direction. The pressure gauge is mounted on the pump. The foot is rotatably connected to the base between an extended position and a first folded position. The foot has a first foot pedal and a second foot pedal. In the extended position, neither the first nor the second foot pedal is located below the pressure gauge along its vertical direction. In the first folded position, the first foot pedal is located below the pressure gauge along its vertical direction. This structure reduces the air pump's transport volume.

[0005] While the aforementioned new patent can reduce the packaging volume of floor-standing air pumps, its overall structure is relatively complex, and the operation of rotating the feet is inconvenient; the air pump must be suspended in the air to rotate the feet. Furthermore, the locking flange of the base and the locking groove of the feet are difficult to engage and disengage, making it laborious and inconvenient to unfold and fold the feet.

[0006] Furthermore, for floor-standing air pumps, the base of this new patent is a component for mounting and stabilizing the pump. However, the design of the previous patent allows the base to rotate relative to the pump, resulting in an unstable connection between the base and the pump, weak structure, and difficulty in withstanding the repeated pressure from the operator during pumping. This becomes a point of failure for the air pump and is easily damaged. Summary of the Invention

[0007] One object of the present invention is to provide a floor-standing air pump with a pressure gauge, which can easily and conveniently store the pressure gauge of the air pump, and change the pressure gauge from the stored state to the used state.

[0008] Another objective of this invention is to provide a floor-standing air pump that can accommodate a pressure gauge, wherein the pressure gauge accommodating structure does not affect the structural integrity of the air pump.

[0009] The pressure gauge-retractable floor-standing air pump provided by this invention includes: A base; a cylindrical portion disposed on the base and protruding upward; the base having at least one foot pedal located on one side of the cylindrical portion; a recessed chamber disposed on the circumferential surface of the cylindrical portion; A cylinder body, the interior of which is a compression space, the bottom end of which is mounted on the cylindrical part of the base; A piston rod; a piston disposed at the bottom end of the piston rod; the piston and the bottom end of the piston rod are installed in the compression space of the cylinder body; A pressure gauge has a head and a manifold connected together, one end of the manifold being a pivot end; a pivot hole located at the pivot end of the manifold; a first flow channel located in the manifold, the two ends of which are connected to the head and the pivot hole; the pivot end of the manifold extends into the chamber of the base.

[0010] With the above structure, the pressure gauge can rotate between the storage position and the use position, with the central manifold as its center of rotation. When the pressure gauge is in the storage position, it coincides with the base; when it is in the use position, it does not coincide with the base. The user can easily rotate the pressure gauge to either the storage position or the use position to store or use the air pump.

[0034] The terms used in this specification and the claims to describe directions and positions, such as up, down, top, bottom, inside, and outside, are based on the directions shown in the diagrams.

[0035] Please see Figures 1 to 3 The present invention provides a floor-standing air pump 10 (hereinafter referred to as an air pump) with a retractable pressure gauge, which includes the following components.

[0036] A base 20 is an elongated shape; a cylindrical part 22 is located on the top surface of the base and protrudes upward; please refer to the accompanying document. Figure 4 The cylindrical portion 22 is hollow, forming an installation hole 23 inside, with its top end penetrating the top surface of the cylindrical portion 22 and its bottom end closed. Preferably, the cylindrical portion 22 is located in the center of the base 20, such that the base forms a first pedal 24 and a second pedal 25 on each side of the cylindrical portion 22. A recessed chamber 26 is disposed radially from the circumference of the cylindrical portion 22 into its interior, forming an open space with an opening; preferably, the chamber has a fan-shaped configuration.

[0037] A hollow cylinder body 30 is a metal tube with a compression space 32 inside. The cylinder body 30 is vertically connected to the base, and its bottom end is installed in the mounting hole 23 of the cylindrical part 22 of the base 20. A clamping ring 33 is a hollow nut that is screwed onto the external thread at the top of the cylindrical part 22 to fix the cylinder body 30. The ring 33 also presses against an airtight ring 34. The airtight ring 34 is located between the top edge of the cylindrical part 22 and the outer peripheral surface of the cylinder body 30 and is pressed by the clamping nut 33 to keep the bottom end of the cylinder body 30 and the cylindrical part 22 airtight.

[0038] A central hole 28 is vertically inserted into the base 20. The central hole 28 intersects with the chamber 26, and its top end extends to the bottom wall of the mounting hole 23 and connects to the compression space 32 of the cylinder 30.

[0039] A piston rod 40 and a piston 42 are disposed at the bottom end of the piston rod 40; the bottom end of the piston rod 40 and the piston 42 are installed in the compression space 32 of the cylinder 30. A cylinder head 44 covers the top end of the cylinder 30, sealing the compression space 32. The top end of the piston rod 40 protrudes from the cylinder head 44. A handle 46 is disposed at the top end of the piston rod 40. By holding the handle 46, the piston rod 40 and the piston 42 can be moved up and down, causing the piston 42 to compress the gas in the compression space 32. The piston 42 is a one-way piston; when it moves towards the bottom end of the cylinder 30, it will compress the gas in the compression space 32. When the piston 42 moves towards the top end of the cylinder 30, the soft ring 43 on the piston's circumference will deform, preventing it from compressing the gas, allowing outside air to replenish the compression space.

[0040] One pressure gauge 50, please refer to Figure 2 and Figures 4 to 5 The device comprises a head 51 and a manifold 52, one end (outer end) of which is connected to the head, and the other end (inner end) of which is a pivot end 521; a pivot hole 54, which is a vertical hole, is provided at the pivot end 521 of the manifold 52; a first flow channel 55 is provided in the manifold, and its two ends connect the head 51 and the pivot hole 54. A rotating shaft 56, a pointer 57, and a dial 58 are installed in the head 51, and the surface of the dial 58 has graduations (not shown). A pneumatic member 59 is provided in the first flow channel 55. When pressurized gas flows into the first flow channel 55, the pneumatic member 59 will be actuated by the pressure of the pressurized gas, and will drive the rotating shaft 56 to rotate through a driving member 591, causing the pointer 57 to rotate and move to a graduation on the dial to display the pressure value. The structure and operation of the pressure gauge 50, which displays the air pressure value, are not the main subject of this invention and will not be described in detail. The pivot end 521 of the pressure gauge 50 is pivotally mounted in the chamber 26 of the cylindrical portion 22 and can rotate in the chamber 26, while the head 51 of the pressure gauge 50 is located outside the chamber 26.

[0041] A central manifold 60 is vertically mounted in the base, serving as the fulcrum for the rotation of the pressure gauge 50, and has a top end and a bottom end; a second flow channel 62 is disposed in the central manifold 60, including a longitudinal section 621, a radial section 622, and an annular groove 623 that are connected. The longitudinal section 621 is arranged along the longitudinal direction of the central manifold 60, and the radial section 622 is arranged along the radial direction of the central manifold. The top end of the longitudinal section 621 extends to the top end of the central manifold, and its bottom end communicates with the radial section 622. The annular groove 623 is disposed on the circumferential surface of the central manifold 60 and communicates with both ends of the radial section 622. The axial manifold 60 passes through the core hole 28 of the base 20 and the pivot hole 54 of the pivot end 521 of the pressure gauge 50, and its top end passes through the bottom wall of the mounting hole 23 from the core hole 28 and enters the compression space 32 of the cylinder 30, so that one end (top end) of the second flow channel 62 is connected to the compression space 32.

[0042] One end piece 65 connects to the top end of the axial manifold 60 from the compression space 32. In this embodiment, the end piece 65 is screwed to the top end of the axial manifold through the same nut. The bottom surface of the end piece 65 contacts the bottom wall of the mounting hole 23. The bottom end of the axial manifold 60 has a large outer diameter protruding ring 601, which abuts against the base 20. When the end piece 65 is tightened, the axial manifold 60 is fixed in the base 20. A connecting hole 66 is axially provided in the end piece 65, and its two ends connect one end of the second flow channel 62 and the compression space 32. The second flow channel 62 of the axial manifold 60 is connected to the compression space 32 of the cylinder 30 through the connecting hole 66.

[0043] Please see Figure 4 The pivot end 521 of the pressure gauge 50 is pivotally connected to the central manifold 60, and can use the central manifold as a fulcrum for rotation in a retracted position (e.g., Figure 1 ) and a location of use (e.g. Figure 9The chamber 26 allows the pressure gauge to rotate at an angle of 60 to 120 degrees, preferably 90 degrees. One end (inner end) of the first flow channel 55 of the pressure gauge 50 is connected to the annular groove 63 of the second flow channel 62. Since the annular groove 63 is a complete circle, the first flow channel 55 and the second flow channel 62 remain connected regardless of the angle to which the pressure gauge 50 is rotated. The axial manifold 60 is the rotation center of the pressure gauge 50 and is connected to the flow channel of the pressure gauge to guide gas flow. A first and a second leak-proof ring 602 and 603 are installed between the circumferential surface of the axial manifold 60 and the peripheral wall of the pivot hole 54 to keep the pivot end 521 of the pressure gauge 50 airtight with the axial manifold 60. A third leak-proof ring 604 is disposed between the circumferential surface of the spindle 60 and the screw hole of the end piece 65; a fourth leak-proof ring 68 is disposed between the bottom surface of the end piece 65 and the bottom wall of the mounting hole 23. The third and fourth leak-proof rings 604 and 68 maintain an airtight seal between the spindle 60, the mounting hole 23 of the cylindrical portion 22, and the end piece 65.

[0044] Please see Figure 6 The air pump 10 further includes: a check valve 70 disposed between the axial manifold 60 and the compression space 32 to prevent pressurized gas from flowing back into the compression space 32 through the second flow channel 62. In this embodiment, the end piece 65 forms part of the check valve 70. A receiving space 72 is formed between the bottom surface of the end piece 65 and the top surface of the axial manifold 60, and connects the connecting hole 66 of the end piece 65 and the top surface of the longitudinal section 621 of the second flow channel 62. The receiving space 72 is formed by an upper recess 721 and a lower recess 722. The upper recess 721 is located on the bottom surface of the end piece 65, and the lower recess 722 is located on the top surface of the axial manifold 60. A plurality of protrusions 74 are disposed on the periphery of the lower recess 722 of the receiving space 72 or on the top surface of the second flow channel 62. Gaps exist between these protrusions 74 to allow gas flow. A check valve 76, spherical in shape, is installed in the receiving space 72 and can move up and down. When the check valve 76 moves toward the connecting hole 66, it will block and seal the connecting hole 66. When the check valve 76 moves toward the second flow channel 62, it will fall on the protrusions 74 and be blocked by the protrusions 74, thus preventing it from sealing the top of the second flow channel 62, allowing gas to flow from the compression space 32 to the second flow channel 62.

[0045] In this preferred embodiment, the air pump 10 has an air outlet channel 84 and an air outlet connector 85, disposed in the manifold 52 of the pressure gauge 50. One end of the air outlet channel 84 is connected to the first flow channel 55, and the other end is connected to the air outlet connector. An air nozzle connector 80 has a flexible hose 82, which is connected to the air outlet connector 75. Compressed gas from the air pump 10 can flow through the second flow channel 62, the first flow channel 55, and the air outlet channel 74, and inflate the tires through the air nozzle connector 70. The positions of the air outlet channel 74 and the air outlet connector 75 can be other options, such as being disposed on the base and connected to the second flow channel, and are not limited to the manifold position shown in this preferred embodiment.

[0046] Figure 1 and Figure 8 The display shows that the air pump 10 is in the storage state, and the pressure gauge 50 is located in the storage position. At this time, the pressure gauge 50 is located directly above the first pedal 24 and coincides with the first pedal 24, so that the air pump 10 has a minimum volume, which is suitable for storage, packaging and transportation.

[0047] To inflate a tire using the air pump 10, the user should turn the pressure gauge 50 to [position missing]. Figures 9 to 11 The pressure gauge is positioned as shown for easy viewing by the user. At this time, the pressure gauge 50 is detached from the first pedal 24 and not aligned with the base 20 or any other pedal. The user can press the second pedal 24, 25, or any other pedal and repeatedly pull and push the piston rod 40 up and down, causing the piston 42 to compress the gas in the compression space 32. As the piston 42 compresses the compression space 32, pressurized gas flows from the compression space 32 into the connecting hole 66, through the check valve 70, and back into the second flow channel 62 of the axial manifold 60 and the first flow channel 55 of the pressure gauge 50. It then flows into the tire through the outlet channel 84, the hose 82, and the valve connector 80, inflating the tire. The pressure gauge 50 displays the inflation pressure value for the user to view.

[0048] When the piston 42 moves to the top of the cylinder 30, outside air will replenish the compression space 32. At this time, the air pressure in the second flow channel 62 is greater than the air pressure in the compression space 32. The anti-reverse member 74 of the anti-reverse member 70 will be pushed upward by the air pressure in the second flow channel 62 and block the connecting hole 66, preventing the pressurized gas in the first flow channel 55 and the second flow channel 62 from flowing back into the compression space 32.

[0049] Please see Figure 7 The pressure gauge 50 has a positioning portion 53 on one surface (e.g., the bottom surface) of its manifold 52. In this preferred embodiment, the positioning portion is a resilient snap or a similar structure. Please refer to [further details omitted]. Figure 2The chamber 26 has a recessed storage positioning point 271 and a use positioning point 272 on one wall (e.g., the bottom wall) to cooperate with the positioning part 53. When the pressure gauge 50 is in the storage position, such as Figure 4 The positioning part 53 engages with the storage positioning point 271 to keep the pressure gauge in the storage position. When the pressure gauge 50 is rotated to the use position, such as Figure 10 As shown, the positioning part 53 engages with the use positioning point 272, keeping the pressure gauge in the use position. When the user rotates the pressure gauge 50, the positioning part 53 can disengage from the storage positioning point 271 or the use positioning point 272.

[0050] The floor-standing air pump provided by this invention utilizes a simple and reasonable structure that allows users to easily rotate the pressure gauge horizontally, facilitating the switching between the storage and use positions. The pressure gauge can be rotated to either the storage or use position without lifting the air pump off the ground, making operation convenient and effortless.

[0051] The base of the floor-standing air pump is the core structure that stabilizes the cylinder. The technical means of this invention is to construct the pressure gauge so that it can rotate relative to the cylinder and the base. The base and the cylinder are fixedly connected and do not rotate relative to each other, thus maintaining the structural strength of the floor-standing air pump.

[0052] The above-described embodiments are merely illustrative of the features of the present invention and not intended to limit it. Any equivalent modifications that fall within the scope of the claims of this invention should be considered within the protection scope of this invention. This invention represents a first-of-its-kind structure for similar articles and enhances their functionality, thus fulfilling the requirements for a patent.
