Abstract
The utility model discloses an inflatable back cushion device suitable for being used on a bus. The inflatable back cushion device structurally comprises a rubber inflator and an inflatable back cushion, and is characterized in that an inflation nozzle is connected to the end part at one end of the inflatable back cushion; two ends of the inflation nozzle are matched with the air outlet end of the inflator; an air inlet valve is arranged on the inner side of the air inlet end of the inflator; an inflation valve is arranged on the inner side at one end of the inflation nozzle, which is connected with the inflatable back cushion; and a deflation mechanism is arranged at one end of the inflation nozzle, which is not connected with the inflatable back cushion, and is composed of an elastic component connected with the inner wall of the inflation nozzle and a compression rod which is connected with the elastic component and close to the inflation valve. By adopting such structure, when the inflatable back cushion is not used, the air in the inflatable back cushion can be released, and the inflatable back cushion can be put in the inflator and is convenient to carry; when the inflatable back cushion is used, the inflation nozzle can be connected onto the inflator to be inflated quickly and then used.
Description
Technical field
The utility model relates to the headrest technology, relates in particular to a kind of Puffer-type headrest technology that is adapted at using on the bus.
Background technology
Present a lot of working clans can use headrest on lunch break or bus, so that more cosily have a rest, the headrest of prior art is substantially all overlapped by cloth and is filled in the interior cotton of cloth cover to be formed, and volume carries inconvenience more greatly; The headrest of Puffer-type as do not have special to fill, the venting instrument, it is also convenient inadequately to use, carry.
Summary of the invention
The purpose of this utility model is: propose a kind of Puffer-type headrest device that is adapted at using on the bus, the function that realization is convenient for carrying and can fills fast, exit is to overcome the deficiencies in the prior art.
For realizing the purpose of this utility model, realize by the following technical solutions: the inflator and the inflation headrest that comprise the rubber material, it is characterized in that: described inflation headrest one end end is connected with charging connector, and all mate mutually with the outlet side of inflator at the two ends of charging connector.
As preferred version: described inflator inlet end inboard is provided with intake valve, and described charging connector is provided with charge valve with the end inboard that the inflation headrest is connected.
As preferred version: described charging connector is not provided with air-release mechanism with the end inboard that the inflation headrest is connected; Air-release mechanism is by the elastic component that is connected with the charging connector inwall, and the depression bar formation that connects elastic component and close charge valve.
Compared with prior art, the beneficial effects of the utility model are: because inflation headrest one end end is connected with charging connector, and all mate mutually with the outlet side of inflator at the two ends of charging connector, like this when not using the inflation headrest, air in the inflation headrest can be bled off, pack in the inflator, be convenient for carrying; Charging connector can be received fast aeration use on the inflator when using the inflation headrest again.
Description of drawings
Configuration state after Fig. 1 has illustrated inflation headrest inflation of the present utility model to finish.
Configuration state when the inflation headrest was put into inflator when Fig. 2 had illustrated that the utility model does not use.
1: intake valve; 2: inflator; 3: the inflation headrest; 4: charge valve; 5: charging connector; 6: depression bar; 7: elastic component.
The specific embodiment
With reference to the accompanying drawings the specific embodiment of the present utility model is made a detailed explanation below.
According to Fig. 1, Fig. 2, the utility model structurally comprises the inflator 2 and the inflation headrest 3 of rubber material, and it is characterized in that: described inflation headrest 3 one end ends are connected with charging connector 5, and all mate mutually with the outlet side of inflator 2 at the two ends of charging connector 5.Described inflator 2 inlet end inboards are provided with intake valve 1, and described charging connector 5 is provided with charge valve 4 with the end inboard that inflation headrest 3 is connected.Described charging connector 5 with in the end that is connected of inflation headrest 3 is not provided with air-release mechanism; Air-release mechanism is by the elastic component 7 that is connected with charging connector 5 inwalls, and depression bar 6 formations that connect elastic component 7 and close charge valve 4.
Described inflator 2 can be diameter 6cm, the hollow cylinder of length 15cm; Described intake valve 1 can be to be close to inboard, inflator 2 end and the elastic sheet rubber that is connected of partial fixing; Described charge valve 4 can be to be connected the elastic sheet rubber that an end inboard is close to and part connects with charging connector 5 with inflation headrest 3.
During use, charging connector 5 is not connected on the outlet side of inflator 2 with the end that inflation headrest 3 is connected, as shown in Figure 1, pushes inflator 2 along direction of arrow interruption and can inflate inflation headrest 3; Only need when not in use to push elastic component 7 with a finger, making elastic component 7 drive depression bar 6 extruding charge valves 4 makes it to open, another hand extruding inflation headrest 3 can be discharged the air in the inflation headrest 3, wait to inflate to inflate after headrest 3 interior air drain and fill in the inflator 2 after headrest 3 carries out simply folding, and charging connector 5 jam-packs can be convenient for carrying.
