Description

TECHNICAL FIELD

[0001] The present invention relates to a foot pump, and more particularly to a foot pump with a pressure gauge. BACKGROUND

[0002] The foot pump has the advantage of labor-saving operation, and thus is widely used. In addition, a pressure gauge is usually arranged on the foot pump for an operator to view the gas pressure value.

[0003] For example, Taiwan Patent No. I460349 discloses a foot pump with a hidden pressure gauge. A housing with a pressure gauge is accommodated in a receiving space provided in the base. When in use, the pressure gauge can be withdrawn from the receiving space for viewing the pressure value. In addition, a foldable pedal is arranged on the other side of the base relative to the pressure gauge. When in use, the pedal is unfolded to a horizontal state for stepping. When not in use, the pedal is folded towards the cylinder for reducing the overall size.

[0004] However, since the pressure gauge is located on the opposite side of the pedal, and the pressure gauge can only move linearly in a single direction and cannot rotate horizontally relative to the cylinder, the pressure gauge cannot be changed according to the standing position of the operator. Therefore, the operator can only view the pressure gauge at a single specific angle, which is inconvenient for operation. In addition, the filling tube of the foot pump is connected to the side of the housing away from the cylinder and adjacent to the pressure gauge. When inflating, the filling tube blocks the pressure gauge, which is inconvenient for viewing the pressure gauge. In addition, the pedal can only provide one-sided stepping, and the cylinder cannot be stably maintained during inflation, which affects the inflation operation. Furthermore, the folding structure of the pedal has poor structural strength, and needs to be folded during use or non-use, which is easy to be damaged.

[0005] Therefore, it is necessary to provide a novel and advanced foot pump with a hidden pressure gauge to solve the above problems. SUMMARY

[0038] The following examples illustrate possible implementations of the present invention, but are not intended to limit the scope of protection of the present invention. The use of "a" or "at least one" before the terms mentioned herein is not a limitation on the quantity, and may also be "multiple" depending on the requirements. Such variations in quantity are also within the scope of protection, as will be stated in advance.

[0039] Please refer to Figures 1 to 10 This illustrates an embodiment of the present invention, wherein the floor-standing air pump 1 with a retractable pressure gauge includes a base 10, an air cylinder 20, and a pressure gauge 30.

[0040] The upper side of the base 10 is provided with a set of grooves 11, which have a pivot hole 115, so that the air cylinder is fixed in the pivot hole of the set of grooves, providing a more stable core structure for the air cylinder; the base 10 also includes two pedal parts 14 located on opposite sides of the set of grooves 11, which can be stepped on by both feet at the same time, or by stepping on one side only; an annular flow channel 12 is formed on the outer peripheral surface of the set of grooves 11; the set of grooves 11 and the annular flow channel 12 are in gas communication; the air cylinder 20 is fixed in the set of grooves 11 on the base 10, and the air cylinder 20 The pressure gauge 30 has a first chamber 21 and a second chamber 22 internally connected to the gas channel 11. It has a display section 31 and a fitting section 32. An airflow channel 33 is formed inside the pressure gauge 30, allowing the display section 31 to communicate with the airflow channel of the fitting section 32. The fitting section 32 has a through opening 324 and is formed on one side of the pressure gauge 30. The fitting section 32 fits onto the mounting slot 11 of the base 10, allowing the pressure gauge 30 to rotate horizontally relative to the air cylinder 20. During air pumping, the pressure gauge 30 can rotate to a different side from the pedal section 14. Gas from the air cylinder 20 can pass through the mounting slot 11 and the annular flow channel 12 into the airflow channel 33 of the pressure gauge 30, causing the display section 31 to show the gas pressure value. The pressure gauge 30 is rotatable to unfold during air pumping (e.g., Figure 5 , Figure 10 (As shown) for ease of use; when not in use, the pressure gauge 30 can be rotated to the same side as the pedal portion 14 (as shown). Figure 6 As shown), it can be compactly stored, reducing the overall size and packaging volume during storage. In addition, since the base 10 of the floor pump 1 is also used as a foot pedal, which is the core structure for securing the pump cylinder 20 during pumping operations, the pump cylinder 20 is fixed on the base 10. The base 10 and the pump cylinder 20 do not rotate relative to each other, but the pressure gauge 30 is configured to rotate relative to the pump cylinder 20.

[0041] Furthermore, the outer circumferential surface of the mounting groove 11 of the base 10 is provided with a threaded section 111. The air cylinder 20 is fitted with a locking ring 40, which is screwed onto the threaded section 111 and axially limits the fitting part 32 between the locking ring 40 and the base 10. The locking ring 40 may contact the fitting part 32, thus preventing the pressure gauge 30 from rotating arbitrarily. Furthermore, the end of the inner circumferential surface of the mounting groove 11 forms an annular conical surface 112 (e.g., ...). Figure 9As shown, the locking ring 40 has a radially inwardly extending annular flange 41, and the air cylinder 20 is further fitted with a first airtight ring 50. The first airtight ring 50 has a tapered ring wall 51. The annular flange 41 presses against the first airtight ring 50 so that the tapered ring wall 51 is embedded between the annular conical surface 112 and the air cylinder 20, which can provide a good airtight effect.

[0042] In this embodiment, the opening 324 of the sleeve portion 32 is sleeved onto the outer peripheral surface of the assembly groove 11 of the base 10. Two second airtight rings 60 are provided between the sleeve portion 32 and the outer peripheral surface of the assembly groove 11, and the annular flow channel 12 is located between the two second airtight rings 60. Specifically, the outer peripheral surface of the assembly groove 11 of the base 10 is provided with a plurality of annular protrusions 113 (e.g., ...). Figure 9 As shown, the annular flow channel 12 is located between the plurality of annular protrusions 113. One end face of the locking ring 40 covers the junction of the sleeve portion 32 and one of the annular protrusions 113. The two second airtight rings 60 are respectively accommodated between adjacent pairs of the plurality of annular protrusions 113. The plurality of annular protrusions 113 can effectively limit the two second airtight rings 60, and the two second airtight rings 60 can ensure the airtightness between the pressure gauge 30 and the outer periphery of the set groove 11.

[0043] Preferably, the bottom side of the sleeve portion 32 is provided with a downwardly extending guide portion 321, and the base 10 is further provided with a guide groove 13 extending around the outer peripheral surface of the set groove 11. The end of the guide groove 13 forms a stop portion 132, which is the end point of the travel of the guide groove 13. The guide portion 321 is embedded in the guide groove 13 and can move along the guide groove 13, so that the pressure gauge 30 can rotate stably and smoothly. In detail, the guide portion 321 further includes a guide protrusion 323, which extends radially from the guide portion 321. The guide groove 13 has at least one positioning recess 131, which is formed in the guide groove 13 or at one end of the guide groove. Rotating the pressure gauge 30 can release the guide protrusion 323 to be positioned in the positioning recess 131, so that the pressure gauge 30 can be kept in position to avoid random rotation.

[0044] Specifically, the set of grooves 11 has at least one through hole 114, which communicates with the annular flow channel 12 for gas. The cylinder wall of the air cylinder 20 has at least one through hole 23, which communicates with the annular flow channel 12 and the second chamber 22 for gas. More specifically, the set of grooves 11 may also have two radially opposite through holes 114. The guide groove 13 extends 180 degrees around the outer circumference of the set of grooves 11. The sleeve portion 32 has at least one through hole 322, which is formed on the side wall 325 of the sleeve portion 32 and communicates with the annular flow channel 12 and the at least one through hole 23 for gas. In use, the pressure gauge 30 can be rotated to one side of the base 10 (e.g.,Figure 1 , Figure 5 As shown), at this time, the through hole 322 of the sleeve part 32 corresponds to one of the through holes 114; or, the pressure gauge 30 can be rotated 180 degrees to the other side of the base 10 (as shown). Figure 10 As shown), at this time, the through hole 322 of the sleeve part 32 corresponds to another through hole 114.

[0045] The air cylinder 20 is provided with a valve 70, which is provided with a one-way ring valve 71 that separates the first chamber 21 and the second chamber 22. The one-way ring valve 71 only allows gas to flow unilaterally from the first chamber 21 to the second chamber 22.

[0046] In this embodiment, the valve 70 passes through the bottom wall 24 of the air cylinder 20 and the bottom wall 15 of the set groove 11 and is locked with a locking fastener 80 (e.g., Figure 8 As shown, the valve 70 is tightly pressed against the bottom wall 24 of the air cylinder 20, and the locking method facilitates assembly, disassembly, replacement, and maintenance. A gas guide ring groove 73 is formed on the outer peripheral surface of the valve 70. The gas guide ring groove 73 is in gas communication with the second chamber 22, allowing the gas to flow from the second chamber 22 into the annular flow channel 12 of the assembled groove 11 into the pressure gauge 30. Preferably, the valve 70 further includes a first mounting ring groove 72 and a second mounting ring groove 74. The air guide ring groove 73 is located between the first mounting ring groove 72 and the second mounting ring groove 74 and is in gas communication with the at least one through hole 23. The one-way ring valve 71 is installed in the first mounting ring groove 72, and a third airtight ring 75 is installed in the second mounting ring groove 74. The one-way ring valve 71 and the third airtight ring 75 are airtightly abutting against the cylinder wall of the air cylinder 20, so that the at least one through hole 23 is located between the one-way ring valve 71 and the third airtight ring 75, ensuring a good airtight effect. The valve 70 further includes an upper flange 76 and a lower flange 77. The upper flange 76 extends radially beyond the lower flange 77. The one-way ring valve 71 is installed between the upper flange 76 and the lower flange 77. The larger diameter upper flange 76 provides a wide range of stable support for the one-way ring valve 71, making it difficult for gas to flow back from the second chamber 22 to the first chamber 21.

[0047] The air cylinder 20 is further provided with a piston 90. The top surface of the valve 70 is formed with a third mounting ring groove 78. An elastic ring 79 is installed in the third mounting ring groove 78. The elastic ring 79 protrudes from the top surface of the valve 70. The piston 90 can move to contact the elastic ring 79. During the air pumping process, the elastic ring 79 can buffer the impact of the piston 90 on the valve 70.

[0048] The pressure gauge 30 also has a hollow connecting pipe 34, which is closer to the sleeve portion 32 than the display portion 31. The connecting pipe 34 and the airflow channel 33 of the pressure gauge 30 are in gas communication with the annular flow channel 12. A filling tube 100 is connected to the connecting pipe 34. The filling tube 100 is for connecting to an object to be inflated (not shown). Since the connecting pipe 34 is closer to the sleeve portion 32 than the display portion 31, the filling tube 100 can rotate with the pressure gauge 30. When the operator holds the filling tube 100 to perform the inflation operation, they can get closer to the object to be inflated and simultaneously view the pressure value on the pressure gauge 30. The structure of the filling tube 100 is not the main subject of this invention and will not be described in detail. A locking cap 110 is fitted onto the filling tube 100 and locked to the connecting pipe 34 to allow gas to flow to the object to be inflated.

[0049] In addition, a horizontal line L perpendicular to the axis of the air cylinder 20 is defined. This horizontal line L passes through the set of grooves 11 and the pressure gauge 30. The horizontal line L can also pass through the annular flow channel 12 of the set of grooves 11 and the airflow channel 33 of the pressure gauge 30. In this way, the pressure gauge 30 is located at a lower horizontal position and is closer to the base 10, which can lower the center of gravity of the floor-standing air pump 1 that can be stored with the pressure gauge, making it more stable during use. It can also rotate horizontally relative to the air cylinder 20, further reducing the overall size and packaging volume when stored.

[0050] Please refer to this again. Figure 11 This is a second preferred embodiment of the floor-standing air pump with a retractable pressure gauge according to the present invention. The same components use the same reference numerals as in the first preferred embodiment, and will not be described again. Specifically, the guide groove 13 of the base 10 can extend 90 degrees around the outer surface of the set of grooves 11, allowing the pressure gauge 30 to rotate to one side of the base 10 during use, i.e., the side opposite to the pedal. However, in other possible embodiments, the guide groove 13 of the base 10 can also extend at different angles around the set of grooves 11.

[0051] The above description describes the preferred embodiments of the present invention and the technical principles applied thereto. For those skilled in the art, any obvious changes such as equivalent transformations or simple substitutions based on the technical solutions of the present invention, without departing from the spirit and scope of the present invention, shall fall within the protection scope of the present invention.
