Description

Technical Field

[0001] The utility model relates to the technical field of air pumps, in particular to an air pump which can conveniently store a hose. Background Art

[0002] There are many types of handheld air pumps on the market. Most of the air outlet hoses of these air pumps are placed separately from the main unit and are only connected when in use. They are inconvenient to store and not very convenient to use. Some air outlet hoses are stored inside the main unit, taken out from the inside of the main unit when in use, and then connected to the air outlet of the main unit. Although the storage problem is solved, it is still inconvenient to use. Some air outlet hoses are fixedly stored at the air outlet of the main unit by extension. When in use, there is no need to reconnect them. They can be used by adjusting the angle of the hose. However, it is known that the fixed storage method of these hoses will increase the overall size of the main unit (in the length direction or width direction), and require more storage and packaging space.

[0009] The air intake windows are reserved and arranged on the surfaces of the front shell and the rear shell.

[0010] Furthermore, the air pump that is convenient for storing the hose also includes:

[0011] The movement is fixedly mounted inside the rear housing and can pump external air to the air outlet hose through an adapter.

[0012] Furthermore, the movement includes a seat body installed inside the rear shell body, a motor is installed at the bottom of the seat body, a driving gear is installed at the driving end of the motor, the interior of the seat body is rotatably connected to a driven gear, the driven gear is meshed with the driving gear, the edge of the driven gear is rotatably connected to a handle rod, and the upper part of the handle rod is connected to a piston.

[0013] Furthermore, an air inlet hole is provided inside the handle rod and the piston, and a second spring piece is connected to the upper part of the piston. One side of the second spring piece is connected to the piston by a screw, and the other side is not connected to the piston.

[0017] The utility model provides an air pump that is convenient for storing a hose. Compared with the prior art, it has the following advantages:

[0018] Beneficial effects:

[0019] The air pump can be hidden in the fixed storage mode of the main body, and there is no need to store the air outlet hose separately. When using it, it can be used by only adjusting the air outlet hose to a proper angle. Compared with the existing technology, the difference is that:

[0020] 1. The arrangement of the hose, the battery cell and the movement. Because the diameter of the movement is larger than that of the battery cell, when the movement and the battery cell are arranged in parallel, there will be a gap in thickness between the battery cell and the movement. This gap can just stack a hose in parallel without increasing the length, width and height of the overall layout.

[0021] 2. After stacking the hoses in parallel, connect one end of the hose to the air outlet through an adapter. The hose can rotate on a fixed axis with the adapter. The above technology solves the storage and portability of the air outlet hoses without increasing the overall size of the host, making it easier to store the host in a smaller space. At the sales end, there is no need for larger packaging, saving costs in materials and transportation. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The circuit board 4 is installed inside the front housing 1, and the surface of the circuit board 4 is respectively integrated with function buttons 41, a display screen 42 and a charging interface 43. The front and bottom of the front housing 1 are respectively reserved with windows 1, 2 and 3. The digital display end of the function button 41, the operation end of the display screen 42 and the charging end of the charging interface 43 are respectively exposed to the outside of the front housing 1 through the windows 1, 2 and 3, which is convenient for users to use and operate.

[0038] The battery cell 5 is installed inside the rear housing 2, and the battery cell 5 is connected in series with the circuit board 4. The air intake window 7 is reserved and arranged on the surface of the front housing 1 and the rear housing 2. When the movement 6 is working and inhaling air, the external air can enter the front housing 1 and the rear housing 2 through the air intake window 7, and be inhaled by the air intake channel 68 of the movement 6.

[0039] The movement 6 includes a seat body 61 installed inside the rear housing 2, a motor 62 is installed at the bottom of the seat body 61, a driving gear 63 is installed at the driving end of the motor 62, a driven gear 64 is rotatably connected inside the seat body 61, the driven gear 64 is meshed with the driving gear 63, a handle rod 65 is rotatably connected to the edge of the driven gear 64, a piston 68 is connected to the upper part of the handle rod 65, an air inlet hole 681 is provided inside the handle rod 65 and the piston 68, a spring piece 682 is connected to the upper part of the piston 68, one side of the spring piece 682 is connected to the piston 68 by a screw 683, and the other side is not connected to the piston 68, a pump head 67 is installed on the upper part of the seat body 61, and a piston cavity 67 is provided at the lower part of the pump head 67 1. A transition chamber 672 is provided at the upper part, and a piston 68 moves inside the piston chamber 671. The piston chamber 671 and the transition chamber 672 are connected through an air guide hole 673. A spring 674 is provided at the bottom end of the transition chamber 672. The edge of the spring 674 is fixedly connected to the pump head 67. The middle part of the spring 674 is provided as a blocking part 675. An air guide part 676 is reserved at the edge. An air outlet channel 69 and a pressure sensor 610 are respectively connected to the surface of the pump head 67. The air outlet channel 69 is connected to the transition chamber 672. The detection end of the pressure sensor 610 is located inside the transition chamber 672. The pressure sensor 610 can detect the pressure data of the gas pumped out by the air pump and display it on the display screen 42.

[0040] When the movement 6 is working, the motor 62 drives the driving gear 63 to rotate. Since the driving gear 63 is meshed with the driven gear 64, the driven gear 64 will rotate accordingly. Since the bottom end of the handle rod 65 is eccentrically connected to the driven gear 64, when the driven gear 64 rotates, the handle rod 65 will continuously swing. While swinging, the handle rod 65 will also move up and down, thereby driving the piston 66 to move up and down inside the piston cylinder. When the piston 66 moves down, air will enter through the air inlet 681. Since one side of the spring sheet 682 is connected to the piston 68 by a screw 683, and the other side is not connected to the piston 68, when air enters, the air will push up the spring sheet 682, causing the non-connected side of the spring sheet 682 to tilt upward. At this time, air can enter the piston cavity 671. When the piston 66 moves up, no air enters the air inlet 681, and the air in the piston cavity 671 is filled with air. The air is squeezed by the piston 66 and wants to go out from the air inlet 681, so it will press down the originally upward spring piece 682, so that the spring piece 682 blocks the air inlet 681. At this time, the air can only flow into the air guide hole 673. When the air flowing into the air guide hole 673 puts pressure on the middle part of the spring piece 1 674, the middle part of the spring piece 1 674, that is, the blocking part 675, will bulge upward. After bulging, the air can flow out from the air guide part 675 around the blocking part 675. 76 flows to the transition chamber 672, and then flows from the transition chamber 672 to the air outlet channel 69, and then enters the adapter 31 and the air supply hose 3. When the piston 66 moves down again, the blocking portion 675 that originally bulged upward will be restored and the air guide portion 676 will be blocked again, so that the air in the transition chamber 672 cannot flow into the piston chamber 671. In other words, the spring piece 1 674 and the spring piece 2 682 inside both act as a one-way valve to prevent air from flowing back.
