[0036] Referring to Figs. 1 and 2 again, Figure 5 and Figure 7 As shown, the linkage plate 5 comprises a linkage plate body 51, and the side face of the linkage plate body 51 is provided with a trigger part 52; the micro switch 61 is arranged on the side face of the linkage plate 5, and the contact of the micro switch 61 corresponds to and matches the trigger part 52, so that when the linkage plate 5 moves backward, the micro switch 61 is triggered by the trigger part 52, and then the air supply component 7 is started; the rear end of the linkage plate 5 and the inner wall of the pump shell 1 are further provided with a linkage plate reset spring 55, which is used for providing the force for the forward reset of the linkage plate 5; the micro switch is further used for terminating the triggered state when the linkage plate 5 moves forward to the initial position, and then the air supply component 7 is stopped.

[0037] Referring to Figs. 1 and 2 again, Figures 3 to 8 As shown, the top side of the pump shell 1 is provided with a key slot 14; the function keys 4 comprise an aerating key 41, an air suction key 42 and a stop key 43, and are installed in the corresponding key slots 14; each key of the function keys 4 comprises a key cap 44, a key rod 45 arranged on the lower side of the key cap 44, and a key reset spring 48 located on the outer side of the key rod 45 and between the key cap and the key slot; the bottom side of the key slot 14 is further provided with a first through hole 15; the linkage plate 5 is arranged below the key slot 14; the function keys 4 are used for converting the pressing force received by the function keys 4 into the power for the backward movement of the linkage plate 5 after the key rod 45 passes through the corresponding first through hole 15 and matches the linkage plate 5.

[0038] Referring to Figs. 1 and 2 again, Figures 6 to 8 As shown, the linkage plate 5 is provided with a second through hole 53 for the key rod 45 of the function keys 4 to pass through; the top side of the rear end of the second through hole 53 is provided with a first inclined surface 54; the key rod 45 is provided with a second inclined surface 47 on the side corresponding to the first inclined surface 54, so that when the function keys 4 move downward under pressure, the linkage plate moves backward by the cooperation of the second inclined surface 47 and the first inclined surface 54.

[0039] Referring to Figs. 1 and 2 again, Figure 6 and Figure 7 , Figure 13 and Figure 14As shown, the button rods 45 of the inflation button 41 and the suction button 42 are provided with button slots 46 near the top side. The button slots 46 cooperate with the rear end of the second through hole 53. When the inflation button 41 or the suction button 42 is pressed down and moves to the position of the button slot 46 at the second through hole 53, the linkage plate 5 moves forward under the action of the linkage plate return spring 55, so that the rear end of the second through hole 53 abuts in the button slot 46, so that the inflation button 41 or the suction button 42 is stuck and kept in the pressed state, and at the same time, the linkage plate 5 is kept in the state of triggering the micro switch 61.

[0040] Refer to Figure 13 and Figure 14 As shown, the stop button 43 does not have a button slot 46, and the distance by which the stop button 43 drives the linkage plate to move backward is greater than the distance by which the inflation button 41 and / or the suction button 42 drive the linkage plate to move backward. This is to ensure that when the stop button 43 is pressed, the linkage plate moves backward and disengages from the button slot 46 of the inflation button 41 or the suction button 42, thereby allowing the inflation button 41 or the suction button 42 to reset under the action of the button reset spring 48. The stop button 43 is also used to reset using the button reset spring 48 after being released, and to disengage from the linkage plate 5, allowing the linkage plate 5 to reset under the action of the linkage plate reset spring 55.

[0041] Refer to Figure 4 , Figure 7 and Figure 8 As shown, a positioning block 16 is also provided on the bottom side of the button slot 14; the positioning block 16 has a guide groove 17 in the front-back direction; the linkage plate 5 is also provided with a third through hole 56; the rear end of the third through hole 56 is provided with a forward-protruding slider part 57; the positioning block 16 passes through the third through hole 56, and the slider part 57 slides in the guide groove 17, which is used to provide a guiding function for the front-back movement of the linkage plate 5.

[0042] Refer to Figure 9 and Figure 10 As shown, the blower assembly 7 includes a blower housing 71, an impeller 72 installed inside the blower housing 71, and a blower motor 73 installed on the bottom side of the blower housing 71; the power output shaft of the blower motor is installed with the impeller; the blower housing 71 also has a blower flow channel, the blower flow channel forms the air inlet 74 on the lower side of the front end face of the blower housing 71 and the air outlet 75 on the upper side of the front end face of the blower housing 71; the air inlet 74 and the air outlet 75 are located on the same plane, so that when the reversing block 8 moves up and down, the reversing block flow channel 82 in the reversing block 8 connects with the air inlet 74 or the air outlet 75.

[0043] Refer to Figure 5 , Figure 11 , Figure 13And Figure 14 As shown in the figure, the reversing block 8 comprises a reversing block body 81, the front port of the reversing block flow channel 82 of the reversing block body 81 is large, and the rear port is small; the rear port of the reversing block flow channel 82 is the same size as the air inlet port 74 and the air outlet port 75; the front port of the reversing block flow channel 82 always corresponds to the first air port 2 in the up and down stroke of the reversing block 8; the top side of the reversing block body 81 is further provided with a pressure receiving platform 83 for cooperating with the key rod 45 of the air suction button 42, so that the reversing block 8 is downwardly actuated by the pressing force of the air suction button 42 to realize the switching from air charging to air suction; the bottom side of the reversing block 8 and the bottom side of the pump shell 1 are further provided with a reversing block reset spring 84, which is used to reset to the initial position when the reversing block 8 loses the pressing force of the air suction button 42 to realize the switching from air suction to air charging.

[0044] Referring again to Figure 1 , Figure 3 and Figure 5 , the pump shell 1 is further provided with a power supply 9 near the bottom side for supplying power to the circuit board 6 and the air blowing assembly 7; the power supply 9 is a rechargeable battery; the circuit board 6 is further provided with a charging interface 62 for providing the function of charging the power supply 9; the pump shell 1 is further provided with a charging hole 19 corresponding to the charging interface 62; the pump shell 1 is further provided with a handle 18; the handle 18 is hinged to the pump shell 1. When not in use, the handle 18 can be folded and stored in the pump shell 1.

[0045] The integrated charging and suction air pump of the embodiment is connected with the air nozzle of the charging product through the first air port when the charging product needs to be charged, and the charging button is pressed. The key rod of the charging button passes through the second through hole on the linkage plate corresponding to the charging button downward, and the second inclined surface of the key rod cooperates with the first inclined surface at the rear end of the second through hole, so that the linkage plate is pushed backward during the pressing of the charging button. The linkage plate triggers the micro switch to start the air blowing motor of the air blowing assembly. At this time, the reversing block is located at the initial position, that is, the reversing block flow channel of the reversing block is in communication with the air outlet of the air blowing assembly. Under the action of the impeller of the air blowing assembly, air is sucked into the pump shell from the second air port, and then enters the air inlet of the air blowing assembly into the air blowing flow channel. The air is transported to the air outlet by the impeller, and then is output to the charging product through the first air port, that is, the charging product is charged. When the charging button is pressed to the lower limit, the key slot on the key rod of the charging button corresponds to the second through hole, and the linkage plate moves forward under the action of the linkage plate return spring, so that the rear end surface of the second through hole of the linkage plate abuts in the key slot of the charging button. At this time, the linkage plate still maintains the triggering of the micro switch, and the charging function continues. At the same time, the charging button can be released, and the charging button is clamped by the linkage plate to maintain the pressed state. When the charging needs to be stopped, the stop button is pressed. Since the distance driven by the stop button to move the linkage plate backward is greater than the distance driven by the charging button, the linkage plate moves backward when the stop button is pressed, so that the second through hole of the linkage plate corresponding to the charging button is separated from the key slot of the charging button. The charging button is lifted upward and reset under the action of the key return spring. At this time, the stop button is released, and the stop button is lifted upward and reset under the action of the key return spring. The linkage plate is no longer constrained by the function button and moves left to the initial position under the action of the linkage plate return spring. The linkage plate no longer triggers the micro switch, and the air blowing assembly stops, that is, the charging is stopped.

[0046] The integrated charging and suction air pump of the embodiment also provides the function of deflating the inflated product. The first air port of the air pump is connected with the air nozzle of the inflated product, the suction button is pressed, the button rod of the suction button penetrates the second through hole on the linkage plate corresponding to the suction button downward, at the same time, the second inclined surface of the button rod cooperates with the first inclined surface at the rear end of the second through hole, so that the linkage plate is pushed backward during the pressing of the inflation button; the linkage plate triggers the micro switch to start the air blowing motor of the air blowing assembly. At this time, the reversing block is also pushed downward by the button rod of the suction button, so that the reversing block flow channel of the reversing block is in communication with the air inlet of the air blowing assembly. Under the action of the impeller of the air blowing assembly, air is sucked out from the inflated product, enters the air blowing flow channel from the air inlet of the air blowing assembly through the first air port and the reversing block flow channel, and is then transported to the air outlet by the impeller, enters the pump shell, and is then discharged from the pump shell to the outside environment through the second air port, that is, the inflated product is deflated. When the suction button is pressed to the lower limit, the button slot on the button rod of the suction button corresponds to the second through hole, and the linkage plate moves forward under the action of the linkage plate return spring, so that the rear end surface of the second through hole of the linkage plate abuts in the button slot of the suction button. At this time, the linkage plate still maintains the triggering of the micro switch, and the suction function continues. At the same time, the suction button can be released, and the suction button is clamped by the linkage plate to maintain the pressed state. When it is needed to stop inflating, the stop button is pressed. Since the linkage plate moves backward by a distance greater than that driven by the suction button, the linkage plate moves backward when the stop button is pressed, so that the second through hole of the linkage plate corresponding to the suction button is separated from the button slot of the suction button. The suction button is reset upward under the action of the button return spring, at the same time, the reversing block loses the pressing action of the suction button, and moves upward to the initial position under the action of the reversing block return spring. The reversing block flow channel is switched from being connected with the air inlet of the air blowing assembly to being connected with the air outlet of the air blowing assembly. At this time, the stop button is released, and the stop button is reset upward under the action of the button return spring. The linkage plate is no longer constrained by the function button and moves left to the initial position under the action of the linkage plate return spring. The linkage plate no longer triggers the micro switch, and the air blowing assembly stops, that is, the suction is stopped.

[0047] The linkage plate of the integrated charging and suction air pump moves under the pressing power of the keys, and through the pressing cooperation with the charging keys and the suction keys, the micro switch cooperating with the linkage plate can be triggered, and the air blowing motor of the air blowing assembly is started; through the design of the key and the linkage plate locking (key slot, second through hole) between the charging keys and the suction keys and the linkage plate, the operation is easier; the linkage plate also cooperates with the pressing of the stop key, and the locking between the linkage plate and the charging keys or the suction keys is released, so that the charging function or the suction function can be stopped by one key; when the suction key is pressed, the movement of the linkage plate is not only driven, but also the movement of the reversing block is driven, so that the reversing block flow channel is switched from the air outlet of the air blowing assembly to the air inlet of the air blowing assembly, and then the operation of switching the charging function to the suction function is realized; the shape of the linkage plate itself is simple and reasonable, and the movement is smooth and not easy to be stuck, through the structure of the linkage plate cooperating with the keys, the mechanical cooperation relationship is used to realize the corresponding function, which is more stable and reliable than through multiple micro switches or other similar electronic control modes; the overall structure of the air pump is compact, the operation is simple, and the design is reasonable.

[0048] The above embodiments should not limit the application in any way, and any technical solutions obtained by equivalent replacement or equivalent conversion fall within the protection scope of the application.
