Abstract
The utility model discloses a built-in type inflation and deflation pump, comprising a housing, a motor, a switch, a fan, a rotary air pipe, an air pipe outer cover and a rotary knob. The rotary air pipe is arranged inside the air pipe outer cover. The upper end of the rotary pipe is connected with a rotary knob. The rotary knob is provided with a cam. The rotary knob drives the cam to rotate in relative to the air pipe outer cover along with the rotary air pipe. The bottom of the rotary air pipe is provided with a projection, and the switch is an inching switch. The outer edge of the cam is contacted with the inching switch. The pump has the advantages of good airtightness and convenient replacement of inflation and deflation.
Description
Technical field
The utility model relates to the air pump technical field, a kind of specifically built-in inflation, venting pump.
Background technique
The built-in air pump that charges and discharge mainly is that some portable aerating equipment are charged and discharged gas, knits the suede bed as gas-filled type and charges and discharge gas, is applied in this qi of chong channel ascending adversely bed.The various products that have on the existing market mainly comprise motor, fan and rotation tracheae, and rotation tracheae structure generally adopts the ventilation that moves up and down, and seal is bad, and gas leakage has influenced tightness easily.It is long also to have inflationtime in addition, can not exit complex structure, the shortcoming that reliability is not high.
The model utility content
The purpose of this utility model charges and discharge the simple built-in inflation of gas shift, venting pump for providing a kind of tightness good.
The technological scheme that realizes the foregoing invention purpose is as follows:
Built-in inflation, venting pump, comprise shell, motor, switch, fan, rotation tracheae, air pipe sleeve and knob, described rotation tracheae is located in the air pipe sleeve, rotation tracheae upper end is connected with knob, knob is provided with a cam, and described knob drives cam and the rotation tracheae rotates with respect to air pipe sleeve together, and described rotation tracheae bottom has projection, described switch is a sensitive switch, and described cam outer rim contacts with sensitive switch.
Described outer casing bottom has piston hole, and the piston hole place is provided with piston and seal ring, connects by connecting rod between piston and the seal ring, and connecting rod is provided with helical spring, and described piston contacts with rotation tracheae bottom.
Described shell is provided with a wire cover, and wire cover is provided with a nylon buckles.
The utility model adopts revolving rotation tracheae device, and ventilation in 180 degree makes tightness more secure.Drive the cam rotation by knob, control sensitive switch, it is convenient that the dress that fills, exits is changed.

Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, built-in inflation, the venting pump, comprise shell 8, be arranged at the motor 10 in the shell 8, switch 9, fan 12, fan guard 11, rotation tracheae 6, air pipe sleeve 7 and knob 1, shell 8 tops are provided with cover plate 2, described rotation tracheae 6 is located in the air pipe sleeve 7, rotation tracheae 6 upper ends are connected with knob 1, knob 1 bottom has gap, and described gap inserts in the projection on rotation tracheae 6 inwalls, and knob 1 is provided with a cam 5, knob 1 is stretched out outside the cover plate by the hole on the cover plate 2, described knob 1 drives cam 5 and rotation tracheae 6 rotates with respect to air pipe sleeve 7 together, and described rotation tracheae bottom has projection, and described switch 9 is a sensitive switch, described cam 5 outer rims contact with sensitive switch 9, described shell 8 bottoms have piston hole, and the piston hole place is provided with piston 14 and seal ring 13, connect by connecting rod between piston 14 and the seal ring 13, connecting rod is provided with helical spring 15, piston contacts with rotation tracheae bottom, and described shell is provided with a wire cover 3, and wire cover is provided with a nylon buckles 4.
The utility model working procedure is as follows: when utilizing turn-knob 1 rotation, drive fixing cam structure, decontrol switch in the position of cam depression, connect power supply, motor is started working, and withstands switch button in the position of cam lobe, powered-down.In Rotate 180 ℃ scope, have respectively: inflation (INFLATE)-close (OFF)-exit (DEFLATE) three gears.
Inflation and venting conversion: rotation tracheae (6)+tracheae cover (7), under the drive of knob, the rotation tracheae rotates, when turning to " inflation (INFLATE) " position, the inflation inlet of rotation tracheae is aimed at the exhaust outlet of fan, the projection of rotation tracheae bottom is backed down piston, the intake grill air that the suction port of rotation tracheae is aimed at the tracheae cover enters from turn-knob, after the fan blade acceleration, enter into the air mattress the inside, otherwise when bleeding, turn-knob turns to: the inflation inlet of rotation tracheae (6) is aimed at the air vent of tracheae cover (7) during " venting (DEFLATE) " position, air overflows by piston hole, go into after fan blade (12) quickens through motor (10) is laggard, the relief opening of rotation tracheae is aimed at the exhaust outlet of fan, and air is discharged to the outside through the rotation tracheae.Powered-down after the air emptying of air mattress the inside.
The airtight working principle of fan blade: after fan blade rotated, air can enter fan blade for the motor radiating and cooling simultaneously through motor, by suction port, directly entered into the air mattress the inside, seldom had air to leak.
The power line lid is unique: the power line lid adopts the Placement of nylon buckles (4), can be movable flexibly, need not fall down again, and easy to use.
