Please be positioned at the schematic representation of primary importance for the engagement portion 123 of mini inflating pump head 10 of the present invention simultaneously with reference to Fig. 5 and Fig. 6.The engagement portion 123 of described head 10 is positioned at the restriction portion 3315 of the grip sleeve group 33 of described aeration tube 30, and the both wing portions 1231 of described engagement portion 123 is corresponding to two restriction stoppers 3316 of described receiving part 3314, the described head 10 of described restriction stopper 3316 restrictions can not break away from described grip sleeve group 33 arbitrarily, the protuberance 1232 of described both wing portions 1231 protrusions of surface falls into the recess 3317 on described two restriction stoppers 3316 surfaces, allow head 10 and the grip sleeve group 33 of aeration tube 30 produce the location by concavo-convex cooperation, make head 10 can be not arbitrarily and grip sleeve group 33 produce relative rotation, further make described head 10 in conjunction with being fixed in described aeration tube 30.
With reference to Fig. 7 to Fig. 9, be positioned at the schematic representation of the second place for the engagement portion 123 of mini inflating pump head 10 of the present invention.Desire to make head 10 and aeration tube 30 away from the time, stir the recess 3317 that protuberance 1232 that described head 10 makes 123 alar parts, 1231 surfaces, described engagement portion leaves restriction stopper 3316, rotate described head 10 90 degree, described alar part 1231 is rotated in restriction portion 3315, make described alar part 1231 leave described restriction stopper 3316, allow described engagement portion 123 corresponding described receiving parts 3314, make described engagement portion 123 by described receiving part 3314, also separate with the grip sleeve group 33 of described aeration tube 30 described engagement portion 123, the binding end 12 of described head 10 is in conjunction with described flexible pipe 20, described head 10 away from aeration tube 30 after, described flexible pipe 20 stretches out in described aeration tube 30.
With reference to Figure 10 and Figure 11, be the head 10 of mini inflating pump of the present invention operation chart when the primary importance.The engagement portion 123 of described head 10 is limited in the grip sleeve group 33 of aeration tube 30, make described head 10 be limited in primary importance, and described head 10 does not separate with described grip sleeve group 33, and the operator produces the aeration effect by aeration tube 30, and sends gas to object to be inflatable.When mini inflating pump was inflated in primary importance, flexible pipe 20 (not seeing among the figure) was collected in the aeration tube 30 and does not expose, and reached to reduce volume and light agile requirement.
With reference to Figure 12, be the head 10 of mini inflating pump of the present invention operation chart when the second place.Rotate described head 10 90 degree, allow receiving part 3314 by aeration tube 30 grip sleeve groups 33 of the engagement portion 123 of head 10 (please simultaneously with reference to Fig. 3), make described head 10 away from the grip sleeve group 33 of described aeration tube 30, and described flexible pipe 20 is stretched out by described aeration tube 30, the operator produces the aeration effect by aeration tube 30, and send gas to object to be inflatable, at this moment, the hand that length by flexible pipe 20 allows the operator grip aeration tube 30 can keep suitable distance with object to be inflatable, offers the user and is similar to the usage mode of large-scale pump and comparatively convenient and have a space of handy aeration tube.
Mini inflating pump of the present invention, be combined with flexible pipe by head, allow head select to be positioned at primary importance or the second place, when wherein being positioned at primary importance, the engagement portion of head is limited to the restriction portion of the grip sleeve group of described aeration tube, and described engagement portion can't break away from described grip sleeve group in addition, flexible pipe is collected in the aeration tube simultaneously, reach the purpose of aeration tube is fixed in the head combination, and can reduce volume and have light agile characteristics.When operator's simple rotation head, namely can discount portion be positioned at the second place, the engagement portion of head makes the engagement portion drive flexible pipe simultaneously and breaks away from the aeration tube corresponding to the receiving part of grip sleeve group, reaches the aeration tube obtains preferable aeration position away from head effect.
Can summarize the present invention with regard to the above and have following advantage:
1. mini inflating pump of the present invention, having primary importance and second place alternative is combined head and is fixed in the aeration tube and flexible pipe is concealed in the aeration tube, in response to different use occasions or user's demand, allow mini inflating pump can select the aeration socket joint near or be away from object to be inflatable.
2. mini inflating pump of the present invention is taken into account simultaneously and is reduced volume, light agile and meet the requirement that mini inflating pump carries easily and have the aeration tube away from the preferable aeration position of object to be inflatable.
3. mini inflating pump of the present invention, the action of controlling primary importance and the second place is quite simple and convenient, only needs rotation head can change into first or the second place.
More than explanation is just illustrative for the purpose of the present invention, and nonrestrictive, those of ordinary skills understand; under the situation that does not break away from the spirit and scope that following claims limit, can make many modifications, change; or equivalence, but all will fall within the scope of protection of the present invention.
