Description
- 1. Field of the Invention
- The present invention relates to a built-in air blower inside an air-cushioned bed, and more particularly to a built-in air blower inside the air bed to inflate or deflate the air-cushioned bed.
- 2. Description of Related Art
- A conventional air-cushioned bed has a large air cell with air contained therein. Due to the cushion effect provided by the air in the air cell, the user lying on the air-cushioned bed is able to have excellent support. In order to facilitate the inflation and deflation of the air cell, the air cell is provided with an air nozzle communicating the interior of the air cell with surrounding air. The user is able to use an air compressor or the like to inflate or deflate the air cell via the air nozzle.
- However, it is well known in the art that even if the size of the air compressor is small, it is still difficult to find suitable storage space for it. Furthermore, because airbeds tend to be used infrequently, such as only once or twice in the summer, it is easy for the compressor to become hidden from view by other things stored around it.
- To overcome the shortcomings, the present invention tends to provide an improved built in air blower for an air-cushioned bed to mitigate the aforementioned problems.
- The primary objective of the present invention is to provide an improved built-in air blower for an air-cushioned bed so that the built in air blower is able to automatically open an air channel for inflating/deflating the air bed.
- Another objective of the present invention is that the air blower is detachably received in a container such that either inflation or deflation of the air cell of the air-cushioned bed is easily accomplished.
- Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
-
FIG. 1 is a schematic perspective view showing that an air blower is received in a casing; -
FIG. 2 is an exploded perspective view showing the relation between the air blower and the casing; -
FIG. 3 is an exploded perspective view of a nozzle assembly mounted on the casing of the present invention; and -
FIG. 4 is a schematic view showing the application of the air blower to activate movement of the nozzle assembly so as to inflate or deflate an air bed connected to the air blower of the present invention. - With reference to
FIG. 1 , the air-blower of the present invention includes a casing (10) having a through hole (11) defined in a side face of the casing (10) so that an interior of the casing (10) is able to communicate with ambient air. - With reference to
FIG. 2 , it is noted that the air blower (60) is capable of sucking air from surrounding atmosphere into the through hole (11) and blowing air out of the air blower (60) via the through hole (11) so as to inflate or deflate an object, e.g. an air bed. - The casing (10) has a U-shaped cross section and further includes a body (not numbered), a sliding seat (24) formed on an inner side face of the body and a position plate (25) slidable with respect to the sliding seat (24).
- The sliding seat (24) includes two oppositely formed ledges (241) each having a notch (2411) defined therein, a recessed area (242) defined centrally in a side face defining the sliding seat (24) and a limiting groove (243) defined in a top portion of a bottom face defining the recessed area (242). Two tracks (244) are respectively formed between the two ledges (241).
- The position plate (25) includes two oppositely formed side walls (251) each having a position ear (2511) integrally extending out therefrom to correspond to the notches (2411) and a truncated edge (2512) formed on a lower portion of the side wall (251), a cap (252) formed between the two side walls (251), a U-shaped cut (253) defined in a lower portion of the position plate (25) to form therein a tongue (254) which has two bosses (2541) oppositely formed on a rear side face of the tongue (254) to correspond to the limiting groove (243). It is noted that the position plate (25) has two extensions (255) oppositely formed on the position plate (25) to correspond to the tracks (244) of the sliding seat (24).
- It is to be noted that the casing (10) has a flange (not numbered) which is to be securely connected to a side face of the air-cushioned bed by any appropriate method known in the art. Therefore, when the flange is received in the air cushioned bed, the connection between the flange of the casing (10) and the side face of the air-cushioned bed is air tight and the through hole (11) communicates with the interior of the air-cushioned bed.
- With reference to
FIGS. 2 and 3 , a nozzle assembly is to be mounted on the casing (10) to connect to a periphery defining the through hole (11) of the casing (10). The nozzle assembly includes a base (30), a linkage (40) and a membrane (50). - The base (30) is a hollow cylinder with two open ends. An annular flange (300) is formed on a peripheral edge of one of the two open ends. A crossbar (31) is securely formed inside and across the base (30). The crossbar (31) has a central hole (32) centrally defined in the crossbar (31) and two positioning holes (33) (only one is shown in the drawing) defined in the crossbar (31) and spaced apart from each other by the central hole (32).
- The linkage (40) includes a substrate (45), a central rod (41) centrally formed on a top face of the substrate (45) to correspond to and extend into the central hole (32) and two auxiliary rods (42) formed on the substrate (45) and spaced apart from each other by the central rod (41) to respectively correspond to and extend into the two positioning holes (33), a spring (43) compressibly mounted on an outer periphery of the central rod (41) and an annular stop (44) securely connected to a free end of the central rod (41) to position the spring (43) on the central rod (41). Besides, the linkage (40) has two apertures (46) oppositely formed on the substrate (45) relative to the auxiliary rods (42).
- The membrane (50) has two extensions (51) formed on a side face of the membrane (50) to correspond to and extend into the two apertures (46) of the linkage (40).
- With reference to
FIG. 4 , it is noted that when the nozzle assembly of the present invention is assembled, the central rod (41) and the two auxiliary rods (42) are respectively extended into the central hole (32) and the positioning holes (33). Then the two extensions (51) are extended into and securely received in the two apertures (46) of the linkage (40). Thereafter, the spring (46) is mounted onto the central rod (41) and the annular stop (44) is securely connected to the central rod (41) to securely sandwich the spring (43) with the crossbar (31). - Therefore, when the nozzle assembly is assembled with the casing (10), the annular flange (300) is securely engaged with the periphery defining the through hole (11) of the casing (10) in an air tight manner. An air blower (60) having a mouth (61), a axle (62), and blades (64) operably connected to the air blower (60), is received in the casing (10). Then after the mouth (61) is extended into the through hole (11), an engaging plate (601) securely formed inside the mouth (61) is able to engage with and push the annular stop (44), which compresses the spring (43) to store a recovery force in the spring (43). Because the annular stop (44) is securely connected to the central rod (41), after the annular stop (44) is pushed by the engaging plate (601), the linkage (40) together with the membrane (50) is moved away from a periphery defining the through hole (11) of the casing (10) so that a gap (70) is defined between the membrane (50) and a periphery defining the through hole (11). After the inflation/deflation process is finished, the force applied to the annular stop (44) is removed so that the membrane (50) together with the linkage (40) is returned to its original position, which seals the through hole (11) in an air tight manner.
- Thereafter, with the change of rotation direction of the blades (64), the air blower (60) is able to expedite inflation and deflation to the air bed without involvement of any additional labor after inflation or deflation is finished.
- It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
