The outer end face of the bumper (2a) is flat. A gasket (10) used to block the channel (la) inside the main body (1) is sleeved over the outer side of the bumper (2a), and the gasket (10) is fixed onto the sealing disk. The first spring (8) is a spring. Its inner end abuts on the elbow zone, and the outer end is sleeved over the outer side of the mounting post and abuts on the inner end of the sealing disk. Under the elastic force from the first spring (8), the gasket (10) on the first seal core (2) can abut on the transition zone and form a seal to block the channel (1a). In one embodiment, in order for the first seal core (2) to move more steadily and without offset, on the outer side of the sealing disk, there are several protruding limiters (2b) used to limit the radial position of the first seal core (2). The limiters (2b) are arranged around the axis of the main body (1) and outside the sealing disk. Here, there are at least 3 limiters (2b).

[0032] One embodiment of the second seal core (5) is tubular. The inside of the second seal core (5) is outlet cavity (5a) and the inner end is closed. The inner end face of the second seal core (5) is flat and abuts on the outer end face of the bumper (2a) on the outer end of the first seal core (2). Several outlet holes (5b) are formed through the side of the second seal core (5), and these outlet holes (5b) are arranged around the axis of the second seal core (5). The sealing structure above comprises an annular bracket (6). The outer side of the bracket (6) is impermeably fixed on the main body (1), and a locating groove (6b) is formed between the outer wall of the bracket (6) and the main body (1). The second seal core (5) passes through the bracket (6) and the outer wall of the second seal core (5) is attached with the annular first seal ring (7) and the second seal ring (13). The first seal ring (7) and the second seal ring (13) are both arranged coaxially with the second seal core (5), and the first seal ring (7) and the second seal ring (13) are arranged on a side near the water inlet end of the outlet holes (5b), and a side near the outlet end (1b), respectively. The first seal ring (7) and the second seal ring (13) can abut on the bracket (6) at the same time, and form a seal on the front and rear sides of the outlet hole (5b). In one embodiment, the outer wall of the bracket (6) has an annular and protruding anchor (6a). The main body (1) comprises a transition zone (1d) and an exit zone (1e). The anchor (6a) is pressed firmly between the transition zone (1d) and the exit zone (1e), and a sealing element is fixed between the anchor (6a) and the transition zone (1d). In one embodiment, the inner wall of the bracket (6) and the outer side of the second seal core (5) are both cylindrical. The outer wall of the second seal core (5) also has a shoulder, and the shoulder is located between the bracket (6) and the opening of the outlet end (1b). The second spring (9) above is a spring. The inner end of the second spring (9) is located inside the locating groove (6b) and abuts on the anchor of the bracket (6), and the outer end abuts on the shoulder.

[0033] Several locking holes (1c) are arranged through the side of the outlet end (1b), and the locking holes (1c) are placed around the axis of the outlet end (1b). The attacher (4) comprises a cylindrical locking sleeve (4a), a homing spring (4b), and several steel balls (4c). These steel balls (4c) are correspondingly arranged inside the locking holes (1c) one by one. Under the elastic force from the homing spring (4b), the locking sleeve (4a) can push the steel balls (4c) partially into the main body (1). In one embodiment, at the outlet end (1b), there is a protruding retainer at the side wall of each locking hole (1c). The protruding retainer can allow the steel ball (4c) to partially enter the main body (1) and prevent the entire steel ball (4c) from dropping into the main body (1).

[0034] On the outer end of the second seal core (5), there is also an annular detacher (5c), which makes the steel ball (4c) not enter the main body (1) when the second seal core (5) moves toward the opening of the outlet end (1b) under the elastic force from the elastic piece. On the inner wall of the detacher (5c), there is a guide surface (5d) for easy connection pipe (3) insertion, and the guide surface (5d) is conical.

[0035] When one embodiment of the quick water intake device is in use, the main body (1) is fixed inside the housing (11) having a mounting cavity, by a mounting frame fixedly connected to the rear side of the main body (1). A water intake port (11a) communicated to the mounting cavity is arranged on one side the housing (11), and the opening of the outlet end (1b) of the main body (1) is facing the water intake port (11a) On the outer side of the outer end of the locking sleeve (4a) sleeved over the outlet end (1b) of the main body (1), there is also a push collar that is rolled outward. The push collar aligns with the water intake port (11a). In one embodiment, the housing (11) may comprise a face panel snap-connected onto the front side of the housing (11). The water intake port (11a) is formed through the face panel. A lid is also hinged to the front side of the outer side, and the lid may cover the whole water intake port (11a). For easy repair and replacement, the inlet end of the main body (1) may be connected to the water supply pipe with a quick coupling structure. The specific quick coupling structure may be the same as that in the attacher (4), or a quick coupling structure of snap-claw type may be used.

[0036] When one embodiment of the quick water intake device is not in use, under the elastic force from the first spring (8) and the second spring (9), the first seal core (2) moves outward, and blocks the channel (la) inside the main body (1) by the gasket (10). At the same time, the second seal core (5) also moves toward the outlet end (b) of the main body (1), and blocks the channel (1a) inside the main body (1) in tandem, by the seal formed between the first seal ring (7) and the second seal ring (13) sleeved over the outer wall of the second seal core (5) and the bracket (6). The steel ball (4c) at the outlet end (1b) is held outside the inner cavity of the main body (1) by the detacher (5c) of the second seal core (5). with the push collar depressed, The locking sleeve (4a) retracts backward and compresses the homing spring (4b).

[0037] In actual use of one embodiment of the quick water intake device, the lid is flipped open, a connection pipe (3) is inserted into the water intake port (11a) and the outlet end (1b) of the main body (1), the second seal core (5) is pushed by the end of the connection pipe (3), compressing the first spring (8). Then the first seal core (2) abutting on the second seal core (5) is driven to move inward the main body (1). The double seal is released and the channel is connected. At this point, the second seal core (5) is pushed away, the detacher (5c) detaches from the locking hole (1c), and the locking sleeve (4a) moves forward under the elastic force from the homing spring (4b) and acts on the steel ball (4c). This makes the steel ball (4c) partially enter the main body (1), and jams the annular groove on the outer wall of the connection pipe (3), achieving the axially fixation of the connection pipe (3). Now it is convenient to take and use the water.

[0038] After the water usage is over, by pressing the push collar the locking sleeve (4a) to compress the homing spring (4b) backward, the blocking on the steel ball (4c) is removed. When the connection pipe (3) is pulled out, the steel ball (4c) is pushed into the locking hole (1c) by the outer wall of the connection pipe (3). At this point, the second seal core (5) moves outward under the elastic force from the second spring (9), and blocks the steel ball (4c) by the detacher (5c) so that it can not enter the main body (1). Hence, the connection pipe (3) may be inserted straightly for the next time. There is no need to push the locking sleeve (4a) again because the steel ball (4c) is pushed into the main body (1) by the locking sleeve (4c). It is convenient for the use.

[0039] When the connection pipe (3) is inserted, in order to ensure the sealing performance between the connection pipe (3) and the second seal core (5), an annular sealing washer used to abut on the end of the connection pipe (3), as well as an O-ring used to abut on the outer wall of the connection pipe (3) are fixed onto the inner side of the outer end of the second seal core (5), respectively.

[0040] Besides the proposal shown above, one embodiment of the sealing structure may also comprise an annular sealing washer fixed onto the main body (1), and the annular sealing washer can block the outlet hole (5b). The water channel may also be blocked by enveloping the whole outlet hole (5b) with this sealing washer. After the second seal core (5) moves inward the main body (1), the sealing washer can not envelop the whole outlet hole (5b), and the channel (1b) is opened again.

[0041] The description of the preferred embodiments thereof serves only as an illustration of the spirit of the invention. It will be understood by those skilled in the art that various changes or supplements in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
