[0038] Referring to Figures 3 to 6 , according to the adjustable-direction water supply pipe fitting of the first aspect embodiment of the present utility model, the water supply pipe fitting includes a bottom blow-down assembly and a limiting member 200. The bottom blow-down assembly includes a first pipe body 110, a connecting member 120, and a blow-down member 130. The first pipe body 110 is provided with a first water inlet passage 111. The connecting member 120 passes through the first water inlet passage 111 and is connected to the first pipe body 110, and one end of the connecting member 120 extends out of the first water inlet passage 111. The blow-down member 130 is provided with a blow-down port 131, and the blow-down port 131 is communicated with the first water inlet passage 111. The blow-down member 130 is rotatably sleeved on the end of the connecting member 120 that extends out of the first water inlet passage 111. The limiting member 200 is detachably connected to the end of the connecting member 120 that extends out of the first water inlet passage 111. The blow-down member 130 is located between the first pipe body 110 and the limiting member 200 to prevent the blow-down member 130 from separating from the connecting member 120. In this way, the user can rotate the blow-down member 130 to adjust the blow-down direction of the blow-down port 131. When installing the water supply pipe fitting, the user does not need to consider the installation angle of the water supply pipe fitting and can make the blow-down direction face the sewage discharge assembly 500 by rotating the blow-down member 130, which can reduce the installation difficulty of the water supply pipe fitting and facilitate the user to assemble the water supply pipe fitting.

[0039] Specifically, when the upper water pipe fitting is installed on the cylinder block 400, the blow-off port 131 is close to the bottom wall of the inner cavity of the cylinder block 400. When water enters the first water inlet passage 111, the water generates a certain impact force acting on the blow-off member 130, causing the blow-off member 130 to have a tendency to float upward. By providing the limiting member 200, the limiting member 200 is detachably connected to the first pipe body 110 and is located above the blow-off member 130. The limiting member 200 can abut against the upper side of the blow-off member 130 to limit the upward floating of the blow-off member 130. Since the blow-off member 130 is rotatably arranged on the connecting member 120, the user can rotate the blow-off member 130 to adjust the blow-off direction of the blow-off port 131. When installing the upper water pipe fitting, the user does not need to consider the installation angle of the upper water pipe fitting and can make the blow-off direction face the sewage discharge assembly 500 by rotating the blow-off member 130, which can reduce the installation difficulty of the upper water pipe fitting and facilitate the user to assemble the upper water pipe fitting.

[0040] It should be noted that a connecting portion 121 is provided on the outer side of the connecting member 120. The connecting portion 121 is connected to the inner wall of the first water inlet passage 111, which can facilitate the connection and fixation of the connecting member 120. It can be understood that a plurality of connecting portions 121 are configured, and the plurality of connecting portions 121 are arranged at intervals along the circumferential direction of the first pipe body 110, which can improve the connection reliability between the connecting member 120 and the first pipe body 110.

[0041] It should be noted that the connecting member 120 is provided with an overflow hole 122. Along the axial direction of the first pipe body 110, the overflow hole 122 penetrates through the connecting member 120. The overflow hole 122 is used to discharge the oil film floating on the water surface to purify the water quality.

[0042] It should be noted that the limiting member 200 is further connected with an extension pipe 210, and the extension pipe 210 is communicated with the overflow hole 122 to increase the height of the water surface in the cylinder block 400.

[0043] Refer to Figure 7 、 Figure 8 In some embodiments of the present invention, a limiting structure is provided between the blow-off member 130 and the first pipe body 110. The limiting structure is used to limit the rotation of the blow-off member 130 around the axis of the first pipe body 110, which can improve the rotation stability of the blow-off member 130 to facilitate the user to adjust the blow-off direction.

[0044] Refer to Figure 7 、 Figure 8, in some embodiments of the present utility model, the limiting structure includes a limiting groove 112 provided at the end of the first pipe body 110 and a limiting protrusion 136 provided on the dirt blowing member 130. The limiting groove 112 extends along the circumferential direction of the first water inlet channel 111. The limiting protrusion 136 is received in the limiting groove 112 and can abut against the side wall of the limiting groove 112, which can limit the rotation of the dirt blowing member 130 around the axis of the first pipe body 110, improve the rotational stability of the dirt blowing member 130, and facilitate the user to adjust the dirt blowing direction.

[0045] Specifically, the limiting groove 112 is a ring structure, coaxially arranged with the first water inlet channel 111, and located outside the first water inlet channel 111. The limiting protrusion 136 correspondingly has a ring structure. When assembling the dirt blowing member 130, the dirt blowing member 130 is sleeved on one end of the connecting member 120 extending out of the first water inlet channel 111, and the limiting protrusion 136 is received in the limiting groove 112 and can abut against the side wall of the limiting groove 112, which can limit the rotation of the dirt blowing member 130 around the axis of the first pipe body 110, improve the rotational stability of the dirt blowing member 130, and facilitate the user to adjust the dirt blowing direction.

[0046] It should be noted that the positions of the limiting groove 112 and the limiting protrusion 136 can be interchanged, that is, the limiting groove 112 is provided on the dirt blowing member 130, and the limiting protrusion 136 is provided on the end face of the first pipe body 110, which will not be elaborated here.

[0047] It should be pointed out that the limiting groove 112 can also be a semi-circular ring structure. In this way, the rotation range of the dirt blowing member 130 can be limited, which will not be elaborated here.

[0048] Of course, in some other specific embodiments, the limiting structure can also be a structure in which a limiting hole and a limiting pin cooperate. The limiting hole is provided on the first pipe body 110, and the limiting pin is provided on the dirt blowing member 130. The limiting hole has an arc structure, and the limiting pin passes through the limiting hole and can abut against the side wall of the limiting hole, which can also limit the rotation of the dirt blowing member 130 around the axis of the first pipe body 110, which will not be elaborated here.

[0049] Refer to Figure 6 、 Figure 7 , in some embodiments of the present utility model, a water outlet 132 is provided on the side of the dirt blowing member 130 away from the dirt blowing port 131, which can increase the water outlet path of the bottom dirt blowing assembly, disturb the water flow in the cylinder body 400, and increase the fluidity of the water in the cylinder body 400.

[0050] It should be noted that the width of the water outlet 132 is smaller than the width of the dirt blowing port 131, so that the amount of water flowing out of the water outlet 132 is less than the amount of water flowing out of the dirt blowing port 131, which can avoid the situation that the water flowing out of the water outlet 132 affects the flow of feces to the sewage discharge assembly 500.

[0051] It is understandable that one or more water outlets 132 may be configured. When multiple water outlets 132 are configured, the multiple water outlets 132 are arranged at intervals along the circumferential direction of the first pipe body 110, and no limitation is made here.

[0052] Referring to Figure 6 、 Figure 7 , in some embodiments of the present utility model, the dirt blowing member 130 includes a main body portion 133 and an adjusting portion 134 connecting the main body portion 133. The dirt blowing port 131 is provided on the main body portion 133. The main body portion 133 is rotatably sleeved on one end of the connecting member 120 extending out of the first water inlet channel 111. The adjusting portion 134 at least partially protrudes from the first pipe body 110, which can increase the operating space of the dirt blowing member 130 to facilitate the user to rotate the dirt blowing member 130.

[0053] Specifically, a first installation space 101 is formed by enclosing between the end of the first pipe body 110 and the limiting member 200. The user can drive the main body portion 133 to move by rotating the adjusting portion 134, so that the dirt blowing port 131 rotates relative to the first pipe body 110. Since one end of the adjusting portion 134 away from the main body portion 133 extends out of the first installation space 101, the operating space of the dirt blowing member 130 can be increased to facilitate the user to rotate the dirt blowing member 130.

[0054] It should be noted that, referring to Figure 4 、 Figure 5 , in order to increase the friction between the main body portion 133 and the limiting member 200, a damping member 300 is provided on the main body portion 133. The damping member 300 is of a sealing ring structure. The damping member 300 is clamped between the main body portion 133 and the limiting member 200, which can increase the friction force received by the main body portion 133 to prevent the main body portion 133 from rotating freely, so that the main body portion 133 can stably stay at any position, and the dirt blowing direction of the dirt blowing port 131 can be controlled, thereby improving the use reliability of the water supply pipe fitting, and no limitation is made here.

[0055] It should be noted that, referring to Figure 6 , a positioning groove 135 is provided on one side of the main body portion 133 close to the limiting member 200. The positioning groove 135 is of an annular structure. The damping member 300 is partially accommodated in the positioning groove 135, which can perform circumferential positioning on the damping member 300, and no detailed description is made here.

[0056] In some embodiments of the present utility model, the adjusting portion 134 and the main body portion 133 are of an integral structure, which can reduce the number of molds, so as to reduce the production and manufacturing cost of the molds, and thus reduce the production and manufacturing cost of the water supply pipe fitting.

[0057] Specifically, the adjusting part 134 and the main body part 133 can be integrally formed by injection molding, which can reduce the number of molds, thereby reducing the production and manufacturing cost of the molds, and further reducing the production and manufacturing cost of the water supply pipe fittings.

[0058] Of course, in some other specific embodiments, the adjusting part 134 and the main body part 133 can be connected by welding or bolting. Among them, the welding methods include but are not limited to resistance welding, ultrasonic welding, laser welding, etc.

[0059] In some embodiments of the present invention, the bottom blow - dirt assembly further includes a second pipe body 140. The second pipe body 140 is provided with a second water inlet channel 141. The first pipe body 110 is detachably connected to the second pipe body 140, and the first water inlet channel 111 is communicated with the second water inlet channel 141. One end of the first pipe body 110 close to the blow - dirt part 130 is used to abut against the bottom wall of the inner cavity of the cylinder block 400, and one end of the second pipe body 140 close to the first pipe body 110 is used to abut against the bottom of the outside of the cylinder block 400, which is convenient for installing the bottom blow - dirt assembly.

[0060] Specifically, the first pipe body 110 and the second pipe body 140 enclose a second installation space 102. One end of the first pipe body 110 close to the blow - dirt part 130 abuts against the bottom wall of the inner cavity of the cylinder block 400, and one end of the second pipe body 140 close to the first pipe body 110 abuts against the bottom of the outside of the cylinder block 400, so that the bottom plate of the cylinder block 400 is clamped between one end of the first pipe body 110 close to the blow - dirt part 130 and one end of the second pipe body 140 close to the first pipe body 110, which is convenient for installing the bottom blow - dirt assembly.

[0061] In some embodiments of the present invention, a threaded connection structure is provided between the first pipe body 110 and the second pipe body 140, which can be applicable to cylinder blocks 400 with different wall thicknesses, so as to improve the versatility of the water supply pipe fittings.

[0062] Refer to Figure 5 、 Figure 8 In some embodiments of the present invention, the threaded connection structure includes a first threaded part 113 provided on the first pipe body 110 and a second threaded part 142 provided on the second pipe body 140. One end of the first pipe body 110 far from the blow - dirt part 130 is accommodated in the second pipe body 140, and the first threaded part 113 is in threaded cooperation with the second threaded part 142, which can be applicable to cylinder blocks 400 with different wall thicknesses, so as to improve the versatility of the water supply pipe fittings.

[0063] Specifically, the first threaded part 113 is an internal - thread structure, and the second threaded part 142 is an external - thread structure. When assembling the water supply pipe fittings, the first threaded part 113 is in threaded cooperation with the second threaded part 142, so that the width of the second installation space 102 can be increased or decreased, which can be applicable to cylinder blocks 400 with different wall thicknesses, so as to improve the versatility of the water supply pipe fittings.

[0064] Of course, in some other specific embodiments, the first threaded portion 113 may also be an external thread structure, and the second threaded portion 142 is an internal thread structure, which will not be elaborated here.

[0065] It should be noted that the threaded connection structure may further include a nut. The second pipe body 140 is sleeved on the first pipe body 110. The first pipe body 110 is provided with the first threaded portion 113, and the nut is sleeved on the first pipe body 110 and is in threaded cooperation with the first threaded portion 113. The nut can push the second pipe body 140 to move in the direction close to the limiting member 200, so that the width of the second installation space 102 is reduced and it can also be applicable to cylinder blocks 400 with different wall thicknesses, which will not be elaborated here.

[0066] Refer to Figure 1 、 Figure 2 According to the fish tank of the second aspect embodiment of the present invention, it includes a cylinder block 400, a sewage discharge assembly 500 and the adjustable-direction water supply pipe fitting of the first aspect embodiment of the present invention. The first pipe body 110 and the sewage discharge assembly 500 are both arranged on the cylinder block 400. The sewage discharge assembly 500 is provided with a sewage discharge channel for discharging feces. The sewage blowing port 131 is close to the bottom wall of the inner cavity of the cylinder block 400 and faces the sewage discharge assembly 500. The user can rotate the sewage blowing member 130 to adjust the sewage blowing direction of the sewage blowing port 131. When installing the water supply pipe fitting, the user does not need to consider the installation angle of the water supply pipe fitting. By rotating the sewage blowing member 130, the sewage blowing direction can be made to face the sewage discharge assembly 500, which can reduce the installation difficulty of the water supply pipe fitting and facilitate the user to assemble the water supply pipe fitting.

[0067] Specifically, when the water supply pipe fitting is installed on the cylinder block 400, the sewage blowing port 131 is close to the bottom wall of the inner cavity of the cylinder block 400. When water enters the first water inlet channel 111, the water generates a certain impact force on the sewage blowing member 130, so that the sewage blowing member 130 has a tendency to float upward. By providing the limiting member 200, the limiting member 200 is detachably connected to the first pipe body 110 and is located above the sewage blowing member 130. The limiting member 200 can abut against the upper side of the sewage blowing member 130 to limit the upward floating of the sewage blowing member 130. Since the sewage blowing member 130 is rotatably arranged on the connecting member 120, the user can rotate the sewage blowing member 130 to adjust the sewage blowing direction of the sewage blowing port 131. When installing the water supply pipe fitting, the user does not need to consider the installation angle of the water supply pipe fitting. By rotating the sewage blowing member 130, the sewage blowing direction can be made to face the sewage discharge assembly 500, which can reduce the installation difficulty of the water supply pipe fitting and facilitate the user to assemble the water supply pipe fitting.

[0068] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brief description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0069] The above has described the present embodiment in detail with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiment, and various changes can be made without departing from the gist within the scope of knowledge possessed by those of ordinary skill in the art.
