Example one
As shown in fig. 1-6, the present embodiment shows an inflating nozzle for a vehicle-mounted inflator, which includes an air pipe joint 1, an air inlet pipe 2, an air outlet pipe 3, and an air suction pipe 4, where the air inlet pipe 2, the air outlet pipe 3, and the air suction pipe 4 are hollow pipe structures; an air inlet channel 5 is formed in the air inlet cylinder 2, an air outlet channel 6 is formed in the air outlet pipe 3, and an air suction channel 7 is formed in the air suction pipe 4; one end of the air pipe joint 1 is connected with an air cylinder of the vehicle-mounted inflating pump, and the other end of the air pipe joint is connected with the air inlet cylinder 2; one end of the air outlet pipe 3 is fixed on the air inlet cylinder 2, the air inlet channel 5 is communicated with the air outlet channel 6, and the other end of the air outlet pipe is used for connecting an external tire; the air suction pipe 4 is connected to one side of the air outlet pipe 3, and the air outlet channel 6 is communicated with the air suction channel 7; the section of the air outlet channel 6 is smaller than that of the air suction channel 7; an airflow escape preventing device is arranged in the air suction pipe 4 and close to the connection position of the air suction pipe 4 and the air outlet pipe 3.
The working principle of the connection vehicle-mounted air pump of the embodiment is as follows: when the inflating nozzle sprays air, the air is directly sprayed from the air inlet channel 5 to the air outlet channel 6, the air pressure in the air suction channel 7 is reduced, and the outside air is sucked into the inflating nozzle from the air suction channel 7 and is sprayed out from the air outlet channel 6, so that the air spraying amount of the inflating nozzle is effectively increased.
The air suction pipe 4 of the present embodiment is connected to one side of the air outlet pipe 3 to prevent the air flow from entering the air outlet pipe 3 from the air pipe joint 1 and then directly flowing out of the air charging connector from the air suction pipe 4.
Meanwhile, the section of the air outlet channel 6 in the embodiment is smaller than the section of the air outlet channel 6 and the section of the air suction channel 7, so that the flow rate of the gas entering the air outlet channel 6 from the air outlet channel 6 is increased, the air pressure is lower, the air pressure is higher relative to the air pressure of the air suction channel 7, and more gas is easily sucked.
More specifically, the airflow escape preventing device in this embodiment includes a first air-permeable layer 8 and a second air-permeable layer 9 that are parallel to each other, where the first air-permeable layer 8 is disposed between the air outlet channel 6 and the second air-permeable layer 9; the first breathable layer 8 is provided with a first through hole 10, the second breathable layer 9 is provided with a second through hole 11, and the section of the first through hole 10 is smaller than that of the second through hole 11.
In the above structure, the first through hole 10 is smaller than the second through hole 11, and the gas is not easily escaped from the suction passage 7.
In one embodiment, in order to further prevent the airflow from escaping, in this embodiment, the first through hole 10 and the second through hole 11 are set to be conical holes, and the end with a small aperture of the conical holes is arranged near the air outlet channel 6, and as the first through hole 10 and the second through hole 11 are set, the gas easily flows from the end with a large aperture to the end with a small aperture. Further, when the air is inflated, the air outlet channel 6 is in a negative pressure state relative to the air suction channel 7, and the air flow is more difficult to escape from the air suction channel 7.
In another embodiment, the first through hole 10 is a circular hole, and the second through hole 11 is a semicircular hole having a radius equal to that of the first through hole 10.
In the above structure, the inner wall of the air suction pipe 4 is provided with a ring-shaped fixing groove 12 for fixing the first breathable layer 8 and the second breathable layer 9. The first ventilation layer 8 and the second ventilation layer 9 are fixed on the inner wall of the air suction pipe 4 through a ring-shaped fixing groove 12.
When the charging connector of the embodiment is assembled, the second breathable layer 9 and the first breathable layer 8 are firstly placed at the annular fixing groove 12, and then the air suction pipe 4 is fixed at one side of the air outlet pipe 3 through welding.
In this embodiment, the air inlet tube 2 is connected with the air outlet tube 3 through a conical tube 16, and the conical tube 16 is a shell structure.
Example two
Referring to fig. 7, the present embodiment is different from the first embodiment in that the airflow escape preventing device of the present embodiment includes a cylinder 13 fixed in the air suction pipe 4, and both ends of the cylinder 13 are open; one end of the cylinder 13 close to the air outlet channel 6 is arranged on a guide plate 14, and the guide plate 14 is obliquely arranged towards the air outlet direction of the air outlet channel 6.
In the above structure, the air flows along the air outlet passage 6 to the air outlet passage 6 during inflation. When the air outlet channel 6 passes through the guide plate 14, the guide plate 14 guides the air flow, so that the air flow can pass through smoothly. The arrangement of the baffle plate 14 makes it more difficult for the air flow to flow out of the suction passage 7, and the flowing air needs to flow back along the baffle plate 14 to overcome the resistance of the negative pressure environment flowing into the suction passage 7 from the outside. It is therefore almost impossible for the baffle 14 to make the air flow escape from the suction channel 7.
When the vehicle-mounted inflator is used, impurities such as dust and the like in the sucked air usually aggravate the abrasion of parts and influence the service life of a vehicle tire, particularly when the vehicle-mounted inflator is used in a sand environment. In this embodiment, a filter layer 15 is further disposed at an end of the cylinder 13 away from the air outlet passage 6. More specifically, the filter layer 15 in this embodiment is a filter sponge.
The filtering sponge can effectively filter impurities such as dust in the air and protect the tire from being worn.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art that various changes in the embodiments and modifications thereof may be made, and equivalents may be substituted for elements thereof; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
