Further, the second air inlet 132 is provided on a sidewall of the second air inlet portion 130. Preferably, the second gas inlet 132 is disposed opposite to the second communication port 131, so that gas can flow from the second communication port 131 directly to the second gas inlet 132, thereby reducing gas flow resistance.
Optionally, to enhance the efficiency of the inflator 1000 in venting, the housing 100 is further provided with a second vent passage 150 in communication with the exterior and the interior of the inflator. Specifically, the second exhaust passage 150 extends along the first direction, and the second exhaust passage 150 is also a circular tube-like structure, and the second exhaust passage 150 is disposed through the upper and lower portions of the housing 100.
The detailed structure of the switching mechanism 300 will now be described with reference to fig. 3 and 5 to 8.
As shown in fig. 3, 5 and 6, the switching mechanism 300 includes a first blocking member 310 and a second blocking member 320. When the switching mechanism 300 is in the first position, the first blocking member 310 blocks the first air outlet 112, the second blocking member 320 keeps the second air inlet 132 open, and when the switching mechanism 300 is in the second position, the first blocking member 310 blocks the first air inlet 111, and the second blocking member 320 blocks the second air inlet 132. The first and second blocking members 310 and 320 are used to switch between the first and second positions, so that when the inflator 1000 inflates, the first exhaust passage is ensured to be in a blocking state, and air leakage is avoided.
Specifically, the first blocking member 310 has the same cross-sectional shape as the first air inlet 110, and the outer periphery of the first blocking member 310 is disposed in cooperation with the inner wall of the first air inlet 110, so that the first blocking member 310 can be blocked at the first air outlet 112. Meanwhile, when the switching mechanism 300 is switched to the second position, the first blocking member 310 can also block the first air inlet 111, and during the switching process, the first blocking member 310 can slide in the first direction inside the first channel.
In addition, the second blocking member 320 has the same plate type structure as the shape of the second air inlet 132, and the area of the second blocking member 320 is not smaller than the second air inlet 132, so that the second blocking member 320 can block the second air inlet 132. Further, the second blocking piece 320 is attached to the inner wall of the second air intake channel, and when the second blocking piece 320 is switched between the first position and the second position, the second blocking piece 320 slides reciprocally in the first air intake channel.
Optionally, to improve the stability of the movement of the second blocking member 320 in the first direction, the switching mechanism 300 further includes a guide assembly 360 disposed between the second blocking member 320 and the inner wall of the first intake passage. The guide assembly 360 includes a guide groove 361 and a guide block 362. Wherein, the guide groove 361 is opened on the inner wall of the first air inlet channel along the first direction, the guide block 362 is disposed on the second blocking member 320, and the guide block 362 is slidably matched with the guide groove 361.
Further, the switching mechanism 300 further includes a switching driving assembly 330, the switching driving assembly 330 is connected with the first blocking member 310 and the second blocking member 320 at the same time, and a user only needs to operate the switching driving assembly 330 to drive the first blocking member 310 and the second blocking member 320 to reciprocate along the first direction, so that switching between the first position and the second position can be achieved, and the switching mechanism is simple in structure and convenient for the user to operate.
Meanwhile, as shown in fig. 5 to 8, the switching mechanism 300 further includes a third blocking member 340, where the third blocking member 340 is also connected to the switching driving assembly 330, and the third blocking member 340 is located at the first position when blocking the second air exhaust channel 150, and the third blocking member 340 is located at the second position when blocking the second air exhaust channel 150, and the switching driving assembly 330 is capable of driving the third blocking member 340 to switch between the first position and the second position. Therefore, the switching driving assembly 330 is simultaneously connected with the first blocking member 310, the second blocking member 320 and the third blocking member 340, so that when inflation or exhaustion is required, a user can switch the first blocking member 310, the second blocking member 320 and the third blocking member 340 between the first position and the second position only by adjusting the switching driving assembly 330, which is convenient to operate and beneficial to improving the air tightness of the inflator 1000. It will be appreciated that the third blocking member 340 is similar to the first blocking member 310 in structure and is also circular in shape, and the outer periphery of the third blocking member 340 is connected to the inner wall of the second air discharge channel 150 and is capable of sliding in the first direction on the inner wall of the second air discharge channel 150 to switch positions.
Further, the housing 100 further includes at least one guide portion 140, each guide portion 140 is provided with a guide hole 141 extending along the first direction, the switching driving assembly 330 includes at least one guide rod 332, the at least one guide rod 332 is disposed in one-to-one correspondence with the at least one guide portion 140, that is, the guide rods 332 and the guide portions 140 are the same in number, each guide rod 332 is disposed through the guide hole 141, and one end of one guide rod 332 located in the second air inlet 130 is connected with the switching driving piece 331, and the other end is connected with the second blocking piece 320. When the position of the switching driving piece 331 is adjusted, the guide rod 332 can move along the first direction in the guide hole 141, so that the second blocking piece 320 is prevented from tilting, the tightness of the second blocking piece 320 for blocking the second air inlet 132 is further ensured, and the air leakage of the air inflation body is avoided.
With continued reference to fig. 5 and fig. 6, it can be understood that, in order to ensure the smoothness of the first air inlet portion 110 and the second air outlet channel 150, the guide portion 140 is further provided with a plurality of air guide holes, and the plurality of air guide holes are disposed at intervals along the circumferential direction of the guide hole 141, so as to ensure the structural strength of the guide portion 140, which is beneficial to reducing the air flow resistance.
In this example, two guide portions 140 are provided on the housing 100, and the two guide portions 140 are located on the inner walls of the second air inlet portion 130 and the second air outlet channel 150, respectively. And one end of one of the guide rods 332 is connected to the switching driving part 331 and the other end is connected to the second blocking part 320. Both ends of the other guide bar 332 are connected to the switching driving part 331 and the third blocking part 340, respectively. However, when the position of the switching mechanism 300 is adjusted, the two guide rods 332 can respectively ensure that the second blocking member 320 and the third blocking member 340 move along the first direction, so as to avoid tilting, thereby ensuring the sealing effect of the second blocking member 320 and the third blocking member 340 and avoiding air leakage of the inflatable body. Further, the first blocking member 310 is connected with the third blocking member 340, when the switching driving member 331 drives the third blocking member 340 to move, the first blocking member 310 can be driven to move at the same time, which is beneficial to simplifying the structure of the switching mechanism 300, reducing the production cost, and facilitating the assembly and maintenance of the inflator 1000 by a user.
With reference to fig. 5 and 6, the switching driving assembly 330 further includes at least one elastic member 333 sleeved on the at least one guide rod 332 along the extending direction of the guide rod 332, and two ends of the elastic member 333 are closed and abutted against the switching driving member 331 and the guide portion 140. When the switching mechanism 300 is in the first position, the elastic member 333 is in a compressed state. When the switching mechanism 300 is at the second position, the switching driving member 331 moves away from the housing 100 along the first direction, and the elastic member 333 extends freely, so as to support the switching driving member 331, and further move and maintain the first blocking member 310, the second blocking member 320 and the third blocking member 340 to the second position, without other external force support, thereby reducing energy consumption. Illustratively, the elastic member 333 is a spring, which has the advantages of simple structure and easy purchase.
Optionally, the switching mechanism 300 further includes a fixing assembly 350, where the fixing assembly 350 is disposed between the housing 100 and the switching driving assembly 330 to fix the position of the switching driving assembly 330 relative to the housing 100, so as to improve the tightness of the inflator 1000 and avoid the air leakage of the body 2000 when the switching mechanism 300 is located at the first position.
As shown in fig. 8, in particular, the fixing assembly 350 includes a fixing protrusion 351 and a buckle 352. Wherein, fixed protruding 351 sets up on casing 100, and buckle 352 sets up on switching drive assembly 330, and buckle 352 and fixed protruding 351 can the joint cooperation. The fixing assembly 350 is simple in structure, and is convenient for a user to adjust the position of the switching mechanism 300, thereby reducing the cost of the inflator 1000. In order to improve the fixing effect of the fixing assembly 350, two sets of fixing protrusions 351 and buckles 352 are disposed on two opposite sides of the driving mechanism.
Further, in order to improve the service life of the fixing assembly 350 and facilitate the user's reciprocation, the fixing assembly 350 further includes a mounting frame 353 and a rotation shaft 354. The mounting frame 353 is two plate structures that set up relatively, is equipped with the mounting hole on the mounting frame 353, and pivot 354 passes buckle 352 and erect in the mounting hole. When the user needs to open the buckle 352 and the fixing protrusion 351, the user only needs to press one side of the buckle 352 away from the fixing protrusion 351, and the buckle 352 rotates around the rotating shaft 354, so that the operation is simple.
Of course, the inflator 1000 further includes a sealing member that covers the positions of the first air intake portion 110, the second air intake portion 130, and the second air discharge passage 150 that communicate with the outside when the inflator 1000 completes inflation or deflation, thereby avoiding air leakage of the inflator.
The operation of the inflator 1000 will now be described with reference to FIGS. 1-8.
First, in a conventional state, the sealing member covers the positions of the first air inlet portion 110, the second air inlet portion 130 and the second air outlet channel 150, which are communicated with the outside, the buckle 352 of the fixing assembly 350 is in snap fit with the fixing protrusion 351, and the switching mechanism 300 is located at the first position, that is, the first blocking member 310 blocks the first air outlet 112, the second blocking member 320 is far from the second air inlet 132, so that the second air inlet 132 is in an open state, and the third blocking member 340 blocks the second air outlet channel 150.
When inflation is required, the user turns on the cover while turning on the power supply. Then the fan rotates in the forward direction to form a pumping force for external air, the external air is sucked into the first air inlet part 110 from the first air inlet 111, enters the accommodating cavity 120 through the first communication port 121, enters the second air inlet part 130 through the second communication port 131 under the driving of the fan, and is then filled into the body 2000 from the second air inlet 132, and the body 2000 is continuously inflated. The body 2000 is filled with weather, the user turns off the power supply, and the seal is covered.
When venting is required, the user opens the cover, and then presses the side of the buckle 352 away from the fixing protrusion 351, so that the buckle 352 rotates about the rotation shaft 354 to disengage the buckle 352 from the fixing protrusion 351. At this time, the elastic member 333 drives the switching driver 331 to move in a direction away from the housing 100. In this process, the first blocking member 310 moves from the first air outlet 112 position to the first air inlet 111 position in the first direction and blocks the first air inlet 111, the second blocking member 320 moves to the second air inlet 132 position in the first direction, and the third blocking member 340 opens in the first direction and away from the housing 100, which is the second air outlet channel 150. At this time, the power is started, the fan rotates in the direction to drive the gas in the body 2000 to flow in from the first exhaust port 112 of the second air inlet portion 130, then flow to the second air inlet 132, enter the accommodating chamber 120 through the first communication port 121, enter the second air inlet portion 130 through the second communication port 131, and be discharged to the external environment through the second exhaust port 133, and meanwhile, the gas in the body 2000 flows from the lower end to the upper end of the second exhaust channel 150, and the gas is discharged.
After the exhaust is completed, the user resets the switching mechanism 300 and the cover in order.
