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 closure piece 310 and a second closure piece 320. When the switching mechanism 300 is located at the first position, the first blocking piece 310 blocks the first exhaust port 112, the second blocking piece 320 keeps the second air inlet 132 open, and when the switching mechanism 300 is located at the second position, the first blocking piece 310 blocks the first air inlet 111, and the second blocking piece 320 blocks the second air inlet 132. The first blocking piece 310 and the second blocking piece 320 are switched between the first position and the second position, so that the first exhaust channel is in a blocking state when the inflator 1000 inflates air, and air leakage is avoided.

Specifically, the first blocking member 310 has the same shape as the cross-sectional shape of the first air intake portion 110, and the outer circumference of the first blocking member 310 is fitted to the inner wall of the first air intake portion 110, so that the first blocking member 310 can block the first exhaust port 112. Meanwhile, when the switching mechanism 300 is switched to the second position, the first blocking member 310 can 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 passage.

Furthermore, the second blocking piece 320 is of the same plate-type structure as the shape of the second air inlet 132, and the area of the second blocking piece 320 is not smaller than that of the second air inlet 132, so that the second blocking piece 320 can block the second air inlet 132. Further, the second blocking piece 320 is attached to the inner wall of the second air inlet channel, and when the second blocking piece 320 is switched between the first position and the second position, the second blocking piece 320 slides in the first air inlet channel in a reciprocating manner.

Optionally, in order to improve the stability of the movement of the second block piece 320 in the first direction, the switching mechanism 300 further includes a guide assembly 360 disposed between the second block piece 320 and the inner wall of the first air intake passage. The guide assembly 360 includes a guide groove 361 and a guide block 362. Wherein, the guide way 361 is seted up on first inlet channel inner wall along first direction, and guide block 362 sets up on second shutoff piece 320, and guide block 362 and guide way 361 sliding fit.

Meanwhile, as shown in fig. 5 to 8, the switching mechanism 300 further includes a third blocking member 340, the third blocking member 340 is also connected to the switching driving assembly 330, the third blocking member 340 is located at the first position when blocking the second exhaust passage 150, the third blocking member 340 is located at the second position when blocking the second exhaust passage 150, and the switching driving assembly 330 can drive the third blocking member 340 to switch between the first position and the second position. It can be seen that the switching driving assembly 330 is connected to the first blocking member 310, the second blocking member 320 and the third blocking member 340 at the same time, so that when inflation or deflation is required, a user only needs to adjust the switching driving assembly 330 to realize switching of the first blocking member 310, the second blocking member 320 and the third blocking member 340 between the first position and the second position, the operation is convenient, and the improvement of the air tightness of the inflator 1000 is facilitated. It is understood that the third blocking member 340 is similar to the first blocking member 310 in structure and is also in the shape of a circular plate, and the outer circumference of the third blocking member 340 is connected to the inner wall of the second exhaust channel 150 and can slide along the first direction on the inner wall of the second exhaust channel 150 to facilitate the switching of the position.

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 and the at least one guide portion 140 are disposed in a one-to-one correspondence, that is, the number of the guide rods 332 and the number of the guide portions 140 are the same, 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 portion 130 is connected to the switching driving member 331, and the other end is connected to the second blocking member 320. When adjusting the position of switching drive piece 331, guide rod 332 can move along the first direction in guiding hole 141 to avoid second shutoff piece 320 position to take place to slope, and then be favorable to guaranteeing the leakproofness of second shutoff piece 320 shutoff second air inlet 132, avoid the gas leakage of gas-filled body.

With continued reference to fig. 5 and 6, it can be understood that, in order to ensure the smoothness of the first air inlet portion 110 and the second air outlet passage 150, a plurality of air guide holes are further disposed on the guiding portion 140, and the plurality of air guide holes are spaced along the circumferential direction of the guiding hole 141, so as to ensure the structural strength of the guiding portion 140, which is beneficial to reducing the airflow resistance.

In this case, the housing 100 is provided with two guide portions 140, and the two guide portions 140 are respectively located on the inner walls of the second air intake portion 130 and the second exhaust passage 150. And one end of one of the guide rods 332 is connected to the switching driving member 331 and the other end is connected to the second blocking member 320. Both ends of the other guide rod 332 are connected to the switching driving member 331 and the third blocking member 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 piece 320 and the third blocking piece 340 move along the first direction, so as to avoid the inclination, thereby ensuring the sealing effect of the second blocking piece 320 and the third blocking piece 340 and avoiding the air leakage of the inflation body. Further, the first blocking piece 310 is connected to the third blocking piece 340, and when the switching driving piece 331 drives the third blocking piece 340 to move, the first blocking piece 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 continued reference to fig. 5 and fig. 6, the switching driving assembly 330 further includes at least one elastic member 333, which is sleeved on the at least one guiding rod 332 along the extending direction of the guiding rod 332, and two ends of the elastic member 333 are closed and abutted against the switching driving member 331 and the guiding portion 140. When the switching mechanism 300 is located at the first position, the elastic member 333 is in a compressed state. When the switching mechanism 300 is located 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 to support the switching driving member 331, so that the first blocking member 310, the second blocking member 320 and the third blocking member 340 move to the second position and are maintained without any other external force, thereby reducing energy consumption. The elastic member 333 is exemplarily a spring, which has advantages of simple structure and easy procurement.

Optionally, the switching mechanism 300 further includes a fixing member 350, and the fixing member 350 is disposed between the housing 100 and the switching driving member 330 to fix the position of the switching driving member 330 relative to the housing 100, so as to improve the sealing performance of the inflator 1000 and prevent air leakage from the body 2000 when the switching mechanism 300 is located at the first position.

Wherein, the fixing protrusion 351 is disposed on the housing 100, the latch 352 is disposed on the switching driving assembly 330, and the latch 352 and the fixing protrusion 351 can be in snap fit. The fixing assembly 350 has a simple 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 oppositely arranged on two sides of the driving mechanism.

Further, in order to improve the service life of the fixing assembly 350 and facilitate the reciprocating operation of the user, the fixing assembly 350 further includes a mounting frame 353 and a rotating shaft 354. The mounting frame 353 is two plate-shaped structures which are oppositely arranged, mounting holes are formed in the mounting frame 353, and the rotating shaft 354 penetrates through the buckle 352 and is erected in the mounting holes. When a user needs to open the buckle 352 and the fixing protrusion 351, the user only needs to press one side of the buckle 352 far away from the fixing protrusion 351, and the buckle 352 rotates by taking the rotating shaft 354 as a shaft, so that the operation is simple.

Of course, the inflator 1000 further includes a sealing member, and when the inflator 1000 completes inflation or deflation, the sealing member covers the positions where the first air inlet 110, the second air inlet 130 and the second air exhaust passage 150 communicate with the outside, so as to prevent the inflation body from leaking.

The operation of the inflator 1000 will now be described with reference to FIGS. 1-8.

First, in a normal state, the sealing members are covered at the positions where the first air intake part 110, the second air intake part 130 and the second exhaust passage 150 communicate with the outside, the snap 352 of the fixing assembly 350 is snap-fitted 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 exhaust port 112, the second blocking member 320 is far away from the second air intake port 132, so that the second air intake port 132 is in an open state, and the third blocking member 340 blocks the second exhaust passage 150.

When inflation is required, the user opens the cover and simultaneously turns on the power supply. Then, the fan rotates in the forward direction to generate a suction force to the external air, the external air is sucked into the first air inlet portion 110 from the first air inlet 111, enters the accommodating chamber 120 through the first communication port 121, enters the second air inlet portion 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 and the user turns off the power supply and covers the sealing member.

When it is necessary to exhaust air, the user opens the cover and then presses the side of the latch 352 away from the fixing projection 351 such that the latch 352 rotates about the rotation shaft 354 to disengage the latch 352 from the fixing projection 351. At this time, the elastic member 333 drives the switching drive member 331 to move away from the housing 100. In the process, the first blocking piece 310 moves from the position of the first exhaust port 112 to the position of the first intake port 111 along the first direction and blocks the first intake port 111, the second blocking piece 320 moves to the position of blocking the second intake port 132 along the first direction, and the third blocking piece 340 moves away from the casing 100 along the first direction and opens the second exhaust passage 150. At this time, the power is turned on, the fan rotates in the direction to drive the gas in the main body 2000 to flow in from the first exhaust port 112 of the second air inlet 130, then the gas flows to the second air inlet 132, enters the accommodating chamber 120 through the first communicating port 121, enters the second air inlet 130 through the second communicating port 131, and is exhausted to the external environment through the second exhaust port 133, and meanwhile, the gas in the main body 2000 flows from the lower end to the upper end of the second exhaust passage 150 to be exhausted.

After the air exhaust is completed, the user can reset the switching mechanism 300 and the covering part in sequence.
