Or as shown in fig. 8, in some embodiments of the present invention, the first adapter 500 is an adapter tube, a sealing groove for placing the second sealing ring 520 is disposed in the second cavity 112, the one end of the first adapter 500 is sealed and connected in the second cavity 112, such that the female pipe joint 100 is connected to the first adapter 500 in a sealing manner, and at this time, the elastic member 400 is disposed between the first adapter 500 and the limiting table 300. The first adapter 500 is used for sealing connection with an internal pipe (air inlet pipe or water inlet pipe) of a water heater (not shown in the drawings), and since the structures of the first adapter 500 required by different pipes are not completely the same, the specific structure of the first adapter 500 is not limited in this embodiment, and a manufacturer can adaptively select the structure of the first adapter 500 according to actual requirements. It should be further noted that, in general, the female pipe joint 100 and the first adapter 500 need only be connected together in a sealing manner, and need not be disassembled, and they are assembled together by the manufacturer, and need not be operated by the user.

A second pipeline 210 is arranged in the male pipe joint 200, a pipe joint part 220 for passing through the flow guide through hole 320 is arranged at one end of the male pipe joint 200, fixture blocks 221 matched with the notches 310 are arranged on the pipe joint part 220, the number of the notches 310 is preferably two, the number of the fixture blocks 221 is preferably two, and the two fixture blocks 221 are linearly distributed on the pipe joint part 220; however, in other embodiments, as long as the number of the latches 221 is not more than the number of the notches 310, the pipe joint portion 220 with the latches 221 can pass through the diversion through hole 320 with the notches 310. Since the elastic direction of the elastic member 400 points to the bottom of the position-limiting table 300, before the two latches 221 are inserted into the second cavity 112, the elastic force of the elastic member 400 needs to be overcome, when the two latches 221 are inserted into the second cavity 112, a user can rotate the pipe joint part 220, so that the two latches 221 are in position-limiting clamping connection with the bottom of the position-limiting table 300, and at this time, the two latches 221 abut against the bottom of the position-limiting table 300 under the elastic force of the elastic member 400.

In addition, a sealing ring groove 240 is formed in the male pipe joint 200, the sealing ring groove 240 is close to the pipe joint part 220, a first sealing ring 241 for sealing the first cavity 111 is limited and arranged in the sealing ring groove 240, and the spacing distance between the first sealing ring 241 and the fixture blocks 221 should meet the requirement that when all the fixture blocks 221 are limited and clamped at the bottom of the limiting table 300, the first sealing ring 241 is located in the first cavity 111; since the fluid can flow from the gap 310 to the first cavity 111, the first sealing ring 241 is required to seal the first cavity 111 to prevent the fluid from leaking out through the first cavity 111. The first sealing ring 241 is made of a soft material, and in order to ensure that the first sealing ring 241 can seal the first cavity 111, the size of the first sealing ring 241 should be slightly larger than that of the first cavity 111. Because the size of the flow guide through hole 320 is smaller than the size of the first cavity 111, the size of the pipe joint part 220 is also smaller than the size of the sealing ring groove 240, that is, one end of the male pipe joint 200 is of a stepped structure, in order to enable the pipe joint part 220 to be smoothly inserted into the second cavity 112, the spacing distance between the fixture block 221 and the stepped surface 250 should be greater than the thickness of the limiting table 300.

The other end of the male pipe joint 200 is provided with a second adapter 600 for sealing connection with an external pipe (not shown in the drawings), a fourth pipeline 610 is arranged in the second adapter 600, and the fourth pipeline 610 is communicated with the second pipeline 210.

Or as shown in fig. 8, in some embodiments of the present invention, the second adaptor 600 is a movable adapter, an internal thread is provided in the second pipeline 210, an external thread is provided at one end of the second adaptor 600, the second adaptor 600 is screwed in the second pipeline 210, so that the male pipe joint 200 and the second adaptor 600 are hermetically connected, and since the second adaptor 600 is a movable adapter, the male pipe joint 200 can rotate relative to the external pipeline. The second adaptor 600 is used for being hermetically connected with an external pipeline, the external pipeline is used for inputting fluid (water or gas) into the water heater, when all the clamping blocks 221 are clamped at the bottom of the limiting table 300 in a limiting manner, namely when the male pipe joint 200 is connected with the female pipe joint 100, the fluid in the external pipeline can sequentially flow through the fourth pipeline 610, the second pipeline 210, the second cavity 112 and the third pipeline 510 and flow into an internal pipeline of the water heater. Since the structures of the second adaptor 600 required by different pipes are not completely the same, the specific structure of the second adaptor 600 is not limited in this embodiment, and a manufacturer can adaptively select the structure of the second adaptor 600 according to actual requirements.

As shown in fig. 6, in some embodiments of the present invention, in order to enable the elastic member 400 to better abut against two of the latch 221, the size of the first cavity 111 is larger than the size of the second cavity 112, but when the size of the first cavity 111 is not larger than the size of the second cavity 112, the use of the pipe joint assembly will not be substantially affected, and this embodiment only adopts the technical scheme that the size of the first cavity 111 is larger than the size of the second cavity 112, but does not impose a mandatory limitation thereon.

In some embodiments of the present invention, in order to increase the contact area between the elastic member 400 and two of the fastening blocks 221, a gasket 410 is disposed between the elastic member 400 and the limiting table 300, and when two of the fastening blocks 221 are inserted into the second cavity 112, two of the fastening blocks 221 abut against the gasket 410. The spacer 410 can increase the contact area between the elastic member 400 and the two latches 221, and can prevent the two latches 221 from being scraped by the elastic member 400.

As shown in fig. 7, in some embodiments of the present invention, in order to limit two of the fixture blocks 221 and prevent the two fixture blocks 221 from rotating by themselves, two grooves 330 are formed at the bottom of the limiting table 300, the two grooves 330 are respectively staggered with the two notches 310, and the two grooves 330 are respectively disposed corresponding to the two fixture blocks 221; specifically, the two grooves 330 are perpendicular to the two notches 310, and when a user inserts two latches 221 into the second cavity 112, the two latches 221 can be respectively and limitedly disposed in the two grooves 330 by rotating the pipe joint part 220 by 90 °. Under the elastic force of the elastic member 400, the latch 221 can abut against the groove 330, and if there is no external force, the two latches 221 cannot rotate by themselves. It is understood that the angle between the arrangement direction of the two grooves 330 and the arrangement direction of the two notches 310 is not only unique, but may also be 45 °, 135 °, and the like, without being limited thereto.

In order to more conveniently limit the fixture block 221 in the groove 330, two inclined surfaces 340 are disposed at the bottom of the limiting table 300, each inclined surface 340 extends from the notch 310 to the groove 330, if the setting height of the notch 310 is higher than the setting height of the groove 330, the inclined surface 340 is inclined downward, and if the setting height of the notch 310 is lower than the setting height of the groove 330, the inclined surface 340 is inclined upward, because the first technical solution can make the fixture block 221 better contact with the gasket 410, so that the fixture block 221 is closer to the groove 330, the technical solution that the setting height of the notch 310 is higher than the setting height of the groove 330 is preferably adopted in this embodiment. In addition, in order to perform unidirectional limiting on the rotation of the pipe joint part 220, a limiting block 350 is disposed in each of the grooves 330 in the clockwise direction or the counterclockwise direction, so that the pipe joint part 220 can only rotate in the direction of the inclined surface 340.
