Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of air pumps, and in particular relates to a built-in air pump. Background Art
[0002] The built-in air pump is a key component of various inflatable products. When in use, the built-in air pump is generally placed on the inner side of the inflatable product, and the built-in air pump can be used to quickly inflate and deflate the inflatable product, so as to achieve normal use and storage of the inflatable product.
[0003] The built-in air pump in the prior art has poor sealing performance, and both air extraction and inflation are slow. The main reason is that the gas in the inflatable product may overflow from the air inlet during inflation, and the external gas may enter the inflatable product from the air inlet during exhaust, resulting in difficulty in quickly filling the inflatable product with gas, or difficulty in completely exhausting the gas in the inflatable product.
[0004] Some built-in air pumps use two motors, one for exhaust and one for inflation. When in use, the exhaust motor, the inflation motor and the solenoid valve are assembled into a whole to form a movement, and the whole movement is accommodated in the shell. When inflation is required, inflation is performed through the inflation motor, and when exhaust is required, exhaust is performed through the exhaust motor. Since two motors are used, the current is high, which can easily damage the mainboard and the solenoid valve.
[0005] In view of this, the utility model aims to provide a built-in air pump, which can achieve a good sealing effect through ingenious structural design. When not working, the gas in the inflatable product will not leak out from the air pump. At the same time, the entire air pump can only take in air from one direction and can only exhaust air from one direction, thereby greatly improving the efficiency of vacuuming and inflation, and ensuring that the gas in the inflatable product is completely vacuumed.

[0036] like Figures 1 to 13As shown, the utility model provides a built-in air pump, including a shell 1, a panel 2, and a pumping and inflating component 3 arranged in a containing space formed by the shell 1 and the panel 2. A first through hole 11 is arranged at the bottom of the shell 1, a sealing ring 4 is arranged between the pumping and inflating component 3 and the first through hole 11, and a knob 5 and a second through hole 6 are arranged on the panel 2. In a non-working state, the pumping and inflating component 3 presses the sealing ring 5 to achieve sealing, so as to prevent the gas in the inflatable product from leaking and escaping. When inflating, air enters from the second through hole 6, passes through the pumping and inflating component 3, and then enters the inflatable product from the first through hole 11; when pumping, the gas in the inflatable product enters from the first through hole 11, passes through the pumping and inflating component 3, and then is discharged from the second through hole 6. The second through hole 6 is arranged on the knob 5.
[0037] The pumping and inflating assembly 3 includes an upper cover 31, a middle cover 36, a lower cover 32 and a bottom plate 33 which are arranged in sequence from top to bottom. A motor 34 is arranged in a first cavity formed by the upper cover 31 and the middle cover 36, a fan blade 35 driven by the motor 34 is arranged in a second cavity formed by the middle cover 36 and the lower cover 32, a third through hole 331 and a fourth through hole 332 are arranged on the bottom plate 33, an air hole 321 which penetrates the third through hole 331 is arranged on the lower cover 32, a through hole 362 is formed on the middle cover 36, a first flow channel 361 is formed on one side of the middle cover 36, a second flow channel 322 is formed on one side of the lower cover 32, and the first flow channel 361 and the second flow channel 322 are penetrated to form a gas flow channel for connecting the first cavity and the fourth through hole 332.
[0038] When inflating or deflating, the motor 34 drives the fan blade 35 to rotate, and the gas enters from the third through hole 331, passes through the air hole 321 and enters the second cavity, then passes through the through hole 362 and enters the first cavity, and finally is discharged from the fourth through hole 332 through the gas flow channel.
[0039] Since the air inlet and outlet (the third through hole 331 and the fourth through hole 332) are arranged in one direction, the gas enters the pumping and inflation component 3 to form pressure, thereby playing a pressurizing role and improving the pumping and inflation efficiency.
[0040] The upper cover 31 includes a main body 311 and a raised portion 312 raised upward from the main body 311. The raised portion 312 is provided with a structure 30 matching the knob 5, so that the rotation of the knob 5 can drive the rotation of the pumping and inflating component 3. In this embodiment, the knob 5 can be rotated clockwise by an angle (such as 60°) or counterclockwise by an angle (such as 60°), thereby driving the rotation of the entire pumping and inflating component 3, so that the third through hole 331 is connected with the first through hole 11 (inflating state), or the fourth through hole 332 is connected with the first through hole 11 (inflating state), or the middle area of the third through hole 331 and the fourth through hole 332 presses the sealing ring 4, thereby sealing the first through hole 11 to prevent air leakage.

The fixing plate 7 is fixed in the housing 1 and does not move. By rotating the knob 5, the first blade 3121 and the second blade 3122 can be driven to rotate, thereby touching the button 81, and the button 81 is turned on and off.
[0042] The fixing plate 7 is also provided with a hand-feeling component 9, which includes a fixing part 91 and a retractable part 92. The outer surface of the protrusion 312 is formed with at least two grooves 3123 and an arc-shaped protrusion 3124 disposed between the grooves 3123. By rotating the knob 5, the protrusion 312 can be driven to rotate, so that the retractable part 92 passes through the arc-shaped protrusion 3124 from one groove 3123 to another groove 3123, so as to achieve a better hand feeling.
[0043] A wire pressing plate 12 is provided on the bottom upper surface of the housing 1 to press the wires to avoid being messy or damaged.
[0044] The bottom of the bottom plate 33 is also provided with a circular protrusion 333, and the upper surface of the bottom of the housing 1 is provided with a limit protrusion 13 matching the circular protrusion 333, and the arc surface is contacted to prevent wear.

[0045] The panel 2 is also provided with a wire hiding groove 21, and the wire hiding groove 21 is provided with a cover plate 22 rotatably connected to the panel 2, and this structure is used for hiding wires.
[0046] When in use, in a non-working state, the middle area between the third through hole 331 and the fourth through hole 332 presses the sealing ring 4, thereby sealing the first through hole 11 to prevent air leakage.
[0047] When it is necessary to switch to the inflated state, rotate counterclockwise (or clockwise) by an angle (such as 60°) so that the fourth through hole 332 is connected to the first through hole 11. At this time, the button 81 is turned on, the motor 34 starts to work, and the fan blade 35 starts to rotate. The air enters the accommodating space of the shell 1 from the second through hole 6, and then enters the pumping and inflating component 3 from the third through hole 331, enters the second cavity through the air hole 311, and then enters the first cavity through the through hole 362, passes through the gas flow channel, and is discharged from the fourth through hole 332, and enters the inflatable product through the first through hole 11.
[0048] When it is necessary to switch to the vacuum state, rotate clockwise (or counterclockwise) by an angle (such as 60°) so that the third through hole 331 is connected with the first through hole 11. At this time, the button 81 is turned on, the motor 34 starts to work, the fan blade 35 starts to rotate, and the air is discharged from the inflatable product, passes through the first through hole 11 and the third through hole 331, enters the vacuum inflatable component 3, enters the second cavity through the air hole 311, and then enters the first cavity through the through hole 362, passes through the gas flow channel, and is discharged from the fourth through hole 332, enters the accommodating space of the shell 1, and is finally discharged from the second through hole 6.
