DETAILED DESCRIPTION

(7) Aspects and advantages of the invention will become apparent from the following detailed descriptions with the accompanying drawings. For purposes of explanation, one or more specific embodiments are given to provide a thorough understanding of the invention, and which are described in sufficient detail to enable one skilled in the art to practice the described embodiments. It should be understood that the following descriptions are not intended to limit the embodiments to one specific embodiment. On the contrary, it is intended to cover alternatives, modifications, and equivalents as can be included within the spirit and scope of the described embodiments as defined by the appended claims.

(8) In the following, one embodiment of the present disclosure will be illustrated. Please refer to FIG. 1 to FIG. 3, where FIG. 1 is a perspective view of a hose assembly according to one embodiment of the present disclosure, FIG. 2 is an exploded view of the hose assembly in FIG. 1, and FIG. 3 is a cross-sectional view of the hose assembly in FIG. 2.

(9) A hose assembly 1 provided in this embodiment is suitable for, for example, garden watering applications. The hose assembly 1 may include a fluid passage 11, a male coupler 12, a blocker 13, a ferrule 14 and a sleeve 15.

(10) The fluid passage 11 may, for example, be configured for fluid such as water to flow therethrough. The fluid passage 11 may include a support part 111 and a tube part 112.

(11) The support part 111 may be made of metal such as copper, but the present disclosure is not limited thereto. The support part 111 may include a first portion 1111 and a second portion 1112 that are connected to each other. The first portion 1111 may have a diameter different from (e.g., smaller than) that of the second portion 1112. The second portion 1112 may have an outlet 1112a at a side thereof away from the first portion 1111. Please be noted that in some other embodiments of the present disclosure, the diameter of the first portion may be larger than or equal to the diameter of the second portion.

(12) The tube part 112 may have one end in fluid communication connection with a fluid supply (not shown) and the other end fixedly sleeved on the first portion 1111. Specifically, please further refer to FIG. 4 and FIG. 5 together with FIG. 1 to FIG. 3, where FIG. 4 is a cross-sectional view of the hose assembly in FIG. 1, and FIG. 5 is a cross-sectional view of the hose assembly in FIG. 1 in which a support part and a tube part are fixed to each other. As shown in FIG. 4, the first portion 1111 of the support part 111 is simply placed inside the tube part 112 with rotational degrees of freedom of the support part 111 with respect to the tube part 112. Then, for example, a tool (not shown) may be inserted into the support part 111 via the outlet 1112a to expand the first portion 1111 of the support part 111 from the inner side of the support part 111, and the expended first portion 1111 may be shown as in FIG. 5. The said tool may, for example, be an expander, but the present disclosure is not limited thereto. By doing so, the first portion 1111 is able to engaged with the tube part 112, such that the support part 111 is fixed with respect to the tube part 112, and the fixity between the tube part 112 and the support part 111 can be firmly secured. Please be noted that the diameter of the expanded first portion 1111 of the support part 111 may be at least partially smaller than that of the second portion 1112, but the present disclosure is not limited thereto. In some other embodiments of the present disclosure, the diameter of the expanded first portion of the support part may be larger than that of the second portion. Please be noted that the configuration of this embodiment, in which the tube part 112 is sleeved on the first portion 1111 of the support part 111 with the smaller diameter, is not intended to restrict the present disclosure.

(13) The male coupler 12 may be rotatably sleeved on the second portion 1112 of the support part 111 of the fluid passage 11 at the outlet 1112a. The male coupler 12 may have a thread part 121 located close to the outlet 1112a. The thread part 121 can be threaded with an end fitting (not shown) such as a sprinkler with female threads for outputting fluid from the fluid passage 11. Please be noted that the configuration of this embodiment, in which the male coupler 12 is rotatably sleeved on the second portion 1112 with the larger diameter of the support part 111, is not intended to restrict the present disclosure.

(14) The blocker 13 may be disposed at a side of the second portion 1112 away from the first portion 1111. Moreover, the blocker 13 may be radially protruded from the second portion 1112 of the support part 111 of the fluid passage 11 at the outlet 1112a to restrict detachment of the male coupler 12 from the outlet 1112a of the fluid passage 11. The blocker 13 may be in a loop shape to form a collar, such that the blocker 13 can block the male coupler 12 with a whole loop. However, the present disclosure is not limited thereto. In some embodiments of the present disclosure, the blocker may be a plurality of tabs that has sufficient mechanical strength and protrudes from the second portion. Further, please be noted that the blocker 13 in this embodiment is made in one piece with the support part 111, but the present disclosure is not limited thereto. In some other embodiments of the present disclosure, the blocker and the support part may be two components able to be assembled together.

(15) The ferrule 14 may be made of metal such as copper, but the present disclosure is not limited thereto. The ferrule 14 may be fixedly disposed on the tube part 112. Specifically, the ferrule 14 may be sleeved on the tube part 112 to restrict the expansion of the tube part 112 from excessive outward movement during the abovementioned expansion of the first portion 1111 of the support part 111. This expansion of the tube part 112 may enable the fixity of the ferrule 14 on the tube part 112, and the ferrule 14 also firmly secures the fixity between the tube part 112 and the support part 111. Moreover, the ferrule 14 may be located at a side of the male coupler 12 away from the blocker 13 to restrict the movement of the male coupler 12 between the blocker 13 and the ferrule 14.

(16) The sleeve 15 may be rotatably sleeved on the fluid passage 11, and the sleeve 15 may be fixed to the male coupler 12. It can be also considered that the sleeve 15 may be rotatably sleeved on the fluid passage 11 through the fixity between the sleeve 15 and the male coupler 12. Therefore, the sleeve 15 can be rotated to rotate the male coupler 12 with respect to the fluid passage 11, which is convenient to screw the male coupler 12 to an end fitting. Moreover, the thread part 121 of the male coupler 12 may be exposed by the sleeve 15 for being conveniently threaded with the end fitting. Please be noted that the sleeve 15 in this embodiment is an assembly with a plurality of components, but the present disclosure is not limited thereto. Further, the sleeve 15 may be made of plastic such as polypropylene (PP) and thermoplastic rubber (TPR), but the present disclosure is not limited thereto.

(17) According to the hose assembly discussed above, since the male coupler and the sleeve can be together rotated with respect to the fluid passage, the blocker and the ferrule that are fixed to one another, the engagement between the male coupler and an end fitting can be easily accomplished simply by rotating the small-sized sleeve, and tangling and twisting of the tube part caused by rotation of the tube part can also be prevented.

(18) Further, with the design of the support part of the fluid passage, the strength at the outlet can be enhanced, such that fluid leakage from the male coupler can be prevented.

(19) The embodiments are chosen and described in order to best explain the principles of the present disclosure and its practical applications, to thereby enable others skilled in the art best utilize the present disclosure and various embodiments with various modifications as are suited to the particular use being contemplated. It is intended that the scope of the present disclosure is defined by the following claims and their equivalents.
