In this embodiment, the sliding groove 402 and the air outlet 404 are both opened on the air nozzle body 410.

As shown in fig. 1 and 5, in one embodiment, the cuff 420 further has an exposed hole 424 communicated with the sleeving hole 422, so that air around the cuff 420 can dissipate heat of the air nozzle body 410 through the exposed hole 424, and heat of the air nozzle body 410 can be conducted to the cuff 420 for heat dissipation, thereby increasing the heat dissipation rate of the air nozzle body 410.

In one embodiment, the inner wall of the cuff 420 is provided with a plurality of abutting strips which are distributed at intervals, the exposed hole is positioned between two adjacent abutting strips, the air faucet body is positioned in the sleeving hole, an air flow communication channel exists between the air faucet body and the inner wall of the cuff, and further air flow enters the cuff through the exposed hole and flows between the inner wall of the cuff and the outer wall of the air faucet body, so that the heat dissipation performance of the air faucet is improved. In the present embodiment, each abutment bar extends in the axial direction of the ferrule 420.

As shown in FIG. 1, to improve the convenience of the inflator 10, in one embodiment, the cuff 420 is detachably connected to the second fixing base 100c for the maintenance and replacement of the air faucet 400, which improves the convenience of the inflator 10.

As shown in fig. 1, 6 and 7, in one embodiment, a surface of the second fixing base 100c facing away from the first fixing base 100a is provided with an insertion groove 120 and a rotation limiting groove 130, which are communicated with each other, and the rotation limiting groove 130 is communicated with the mounting hole 110. The side wall of the ferrule 420 is protruded with an arc-shaped protrusion 423, and the ferrule 420 is inserted into the rotation-restricting groove 130 through the insertion groove 120, that is, the ferrule 420 can be inserted into the rotation-restricting groove 130 only along the direction of the arc-shaped protrusion 423 corresponding to the insertion groove 120. The arc-shaped protrusion 423 is configured to be retained in the rotation-retaining groove 130 when the ferrule 420 rotates relative to the second fixing seat 100c by a predetermined angle, and the minimum value of the inner diameter of the rotation-retaining groove 130 is equal to the maximum value of the inner diameter of the insertion groove 120. The inner diameter of the insertion groove 120 is reduced along the direction in which the ferrule 420 is rotatably retained in the rotation-retaining groove 130 relative to the second fixing seat 100c, so that the arc-shaped protrusion 423 is retained in the rotation-retaining groove 130 after rotating by a predetermined angle, and the ferrule 420 is reliably connected with the second fixing seat 100 c.

In the present embodiment, the insertion groove 120 includes a fan-shaped groove 121 and a circular groove 123 communicating with each other, the fan-shaped groove 121 and the circular groove 123 both communicating with the rotation restricting groove 130, and the diameter of the fan-shaped groove 121 is larger than that of the circular groove 123. The arc-shaped boss 423 is a fan-shaped boss, the arc-shaped boss 423 is matched with the fan-shaped groove 121, so that the arc-shaped boss 423 can only be inserted into the rotation limiting groove 130 just opposite to the fan-shaped groove 121, and the inner diameter of the insertion groove is reduced along the direction that the hoop rotates relative to the second fixing seat and is limited in the rotation limiting groove. When the arc-shaped protrusion 423 rotates by a predetermined angle relative to the second fixing seat 100c along with the ferrule 420, the arc-shaped protrusion 423 is staggered with the fan-shaped groove 121 in the rotation limiting groove 130, so that the arc-shaped protrusion 423 is limited in the rotation limiting groove 130 after rotating by the predetermined angle. The fan-shaped groove 121 and the circular groove 123 are both arc-shaped groove structures.

As shown in fig. 5 and 5a, in order to reliably rotationally position the arc-shaped boss in the rotation-limiting groove 130 while preventing the arc-shaped boss from being excessively rotated, further, the inner diameter of the rotation-limiting groove 130 is reduced in the direction in which the arc-shaped boss 423 is screwed into position, so that the arc-shaped boss is rotated by a predetermined angle and then positioned in the rotation-limiting groove. In this embodiment, the inner diameter of the rotation-limiting groove is non-uniformly smaller along the screwing direction of the arc-shaped boss, that is, the inner diameter of the rotation-limiting groove comprises a large-diameter area 130a and a small-diameter area 130b which are communicated with each other, and the inner diameter of the large-diameter area is larger than that of the small-diameter area. The inner diameters of the arc inner walls in the large-diameter area are equal. In a similar way, the inner diameters of the arc inner walls in the small diameter area are equal. The inner diameter of the small-diameter section is greater than or equal to the inner diameter of the circular groove 123, and the inner diameter of the small-diameter section is smaller than the inner diameter of the sector groove 121. The inner diameter of the large-diameter area is larger than or equal to the inner diameter of the fan-shaped groove. The large-diameter area and the small-diameter area are both arc grooves. The part of the large-diameter area is correspondingly communicated with the fan-shaped groove, and the part of the large-diameter area is correspondingly communicated with the circular groove. The small diameter area is correspondingly communicated with the circular groove. When the arc boss of cuff inserts the big footpath district of rotatory spacing groove through the sector groove when distinguished, rotatory cuff makes the arc boss rotate towards path district direction by the big footpath district of spacing groove, until arc boss butt in the position of the adjacent path district of big footpath district inner wall, the arc boss is located the position that big footpath district corresponds with the circular recess this moment, makes the arc boss rotatory location in rotatory spacing inslot reliably, avoids the arc boss rotatory excessively simultaneously. It is understood that, in other embodiments, the inner diameter of the rotation-limiting groove may also gradually decrease along the screwing-in positioning direction of the arc-shaped boss, that is, the inner diameter of the rotation-limiting groove may also gradually decrease along the screwing-in positioning direction of the arc-shaped boss.

As shown in fig. 6 and 7, in order to screw the arc-shaped boss into the rotation limiting groove 130 quickly, a first guiding inclined plane 423a is disposed at the front end of the arc-shaped boss in the direction of screwing into the rotation limiting groove 130, and a second guiding inclined plane 138 corresponding to the first guiding inclined plane is disposed on the inner wall of the rotation limiting groove, so that the resistance applied to the arc-shaped boss during the rotation process in the rotation limiting groove is small, and the arc-shaped boss is screwed into the rotation limiting groove 130 quickly.

As shown in fig. 5a and fig. 6, in order to determine whether the arc-shaped boss is accurately screwed into the rotary limiting groove 130, the second fixing seat 100c is further provided with a bare slot 135 communicated with the rotary limiting groove, when the arc-shaped boss is screwed into the rotary limiting groove 130 in place, the arc-shaped boss is located in the bare slot, so that a user can determine whether the arc-shaped boss is accurately screwed into the rotary limiting groove 130, the use convenience of the inflator pump is improved, meanwhile, the air flow can flow in the rotary limiting groove through the bare slot, the air flow in the rotary limiting groove can enter the bare slot to dissipate heat on the surface of the air nozzle body, and the heat dissipation performance of the air nozzle is improved. In this embodiment, the second guiding inclined surface is disposed on the inner wall of the rotation limiting groove near the bare empty groove.

As shown in FIG. 6, in one embodiment, inflator 10 further comprises a retaining member (not shown). The second fixing base 100c further defines a locking hole 150 communicating with the insertion slot 120, the locking member is located in the locking hole 150 and screwed with the second fixing base 100c, and the locking member abuts against the sidewall of the ferrule 420, so as to prevent the ferrule from accidentally rotating relative to the second fixing base, and thus the ferrule 420 is better fixed and installed on the second fixing base 100 c. In the present embodiment, the locking hole 150 communicates with the circular groove 123. The locking piece is a screw or a bolt.

In other embodiments, the connection manner of the ferrule and the second fixing seat is not limited to the positioning connection by the way of protruding the arc-shaped boss on the ferrule, and may also be a threaded connection or a snap connection.

As shown in FIG. 5, in one embodiment, chute 402 opens at a side of nozzle body 410 adjacent to driven gear 520, allowing piston link assembly 300 to be better slidably coupled to nozzle body 410 via chute 402, while allowing inflator 10 to be more compact.

Two ends of the fixing plate 100b extend to the first fixing seat 100a and the second fixing seat 100c respectively, and the fixing plate 100b, the first fixing seat 100a and the second fixing seat 100c enclose a containing cavity 100d together. In this embodiment, the transmission assembly 500 is disposed in the accommodating cavity 100d and movably connected to the fixing plate 100 b. The piston and connecting rod assembly 300 is partially disposed within the receiving chamber 100d and is rotatably coupled to the drive assembly 500. Because fixed plate 100b, first fixing base 100a and second fixing base 100c integrated into one piece, make fixed plate 100b, the material of first fixing base 100a and second fixing base 100c all the same, including first fixing base 100a, fixed plate 100b and second fixing base 100c are the heat-conducting plates, make mounting bracket 100 have better heat conductivity, need not to set up the radiator again and can satisfy the heat dissipation demand, not only simplify the structure, reduce the volume, and improve the heat dispersion of inflator pump 10.
