Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.

Referring to fig. 1 to 2, in an embodiment, an extraction hose 10 includes a first connector 11, a second connector 12, a hose body 13 and a protective sleeve 14; the first joint 11 comprises an integrally formed threaded joint 111 and a first tensile decorative sleeve 112, the second joint 12 comprises an integrally formed ball joint 121 and a second tensile decorative sleeve 122, and the first tensile decorative sleeve 112 and the second tensile decorative sleeve 122 are respectively fixedly sleeved at two ends of the hose body 13.

Further, the protective sleeve 14 is fixedly sleeved outside the hose main body 13, one end, close to the first joint 11, of the hose main body 13 is defined as a tail end, the ratio of the distance from the center of the protective sleeve 14 in the axial direction to the tail end of the hose main body 13 to the length of the hose main body 13 is defined as a, the value range of a is 0.2-0.4, preferably, the value of a is one third, namely the protective sleeve 14 is preferably sleeved and fixed at the position, away from the first joint 11, of the hose main body 13, the hose length of a household dishwashing table is 1.5m, and the distance between the protective sleeve 14 and the tail end of the hose main body 13 is 450 mm-550 mm.

Wholly adopt protective sheath 14 to combine hose main part 13 structure can effectively solve present extraction formula hose 10 and lead to the damage by the long-term friction of gravity hammer easily, the technical problem that life reduces, and protective sheath 14 adopts such accurate position setting can effectively guarantee that most pipeline of hose main part 13 can be pulled out in the middle of using farther distance simultaneously, can also guarantee the function of automatic withdrawal simultaneously.

Referring to fig. 1, in the embodiment, the thickness of the protective sheath 14 is defined as h, wherein the value of h is in a range of 0.3mm to 4mm, preferably, the value of h is 2mm, and the protective sheath 14 with such a thickness can ensure that the strength thereof is high enough, so that the protective sheath 14 and the hose as a whole are more durable under the friction of a gravity hammer, and cannot be pressed by a necking machine too difficultly due to too high thickness.

Further, the length of the protective sleeve 14 is defined as d, wherein the value range of d is 10 mm-30 mm, preferably, the value range of d is 16mm, the protective sleeve 14 can be easily compressed by adopting the length setting, the size of the gravity hammer can be matched, and excessive waste of materials can be avoided.

Referring to fig. 1, in the embodiment, the protective sleeve 14 is a stainless steel sleeve or a vertical injection molding sleeve, specifically, the stainless steel sleeve is riveted outside the hose body 13 by a necking machine, and the injection molding sleeve directly injects the protective sleeve 14 outside the hose body 13 by a vertical injection molding method, so that the protective sleeve 14 made of two materials can effectively protect the hose and effectively prevent the hose body 13 from being worn by a gravity hammer.

Referring to fig. 1, in an embodiment, the hose body 13 includes an inner tube 131 and a polyester layer 132 covering the outer side of the inner tube 131, the inner tube 131 is non-stretchable and is made of plastic, the inner tube 131 may be a common pipe such as a corrugated tube or a flat tube, and the polyester layer 132 is woven from polyester monofilaments. Adopt such layering setting can effectively strengthen the hardness of polyester layer 132, compare in the nylon materials outside the normal hose more can be convenient for provide sufficient holding power in the throat process of throat machine, the hand feel when still guaranteeing hose main part 13 reaches the best simultaneously.

Specifically, the thickness of the polyester layer 132 is defined as r, wherein the value range of r is 0.75 mm-5 mm, and the hardness and the strength of the polyester layer 132 can be effectively protected by adopting the thickness setting, and meanwhile, the material cost can be reduced to the greatest extent.

Besides, the first joint 11 and the second joint 12 are pressed and riveted outside the hose body 13 through a necking machine, a mandril is axially arranged at the center of a necking cavity of the necking machine and used for adjusting the length of the hose body 13 which can stretch out, so that the first joint 11 and the second joint 12 of the hose body 13 can be just positioned in a die in the necking machine after being respectively stretched into the necking machine, and the first tensile decorative sleeve 112 and the second tensile decorative sleeve 122 can be accurately pressed and riveted to be necked, similarly, when the protective sleeve 14 is a stainless steel sleeve, the protective sleeve 14 is also pressed and riveted through the necking machine in the mode, but the matching of the mandril is not needed at the moment, because the length of the processed hose body 13 is generally the same size, and the necking machine is customized for the hose with the length, so hose main part 13 stretches into the back, the required riveted position that compresses tightly of protective sheath 14 is exactly the position of throat built-in mould, and the internal diameter of protective sheath 14 is 1mm ~2mm bigger than the external diameter of hose main part 13, not only can be convenient for at first protective sheath 14 embolias hose main part 13 comparatively conveniently, guarantee simultaneously that the throat machine does not need work just can realize the compressing tightly of protective sheath 14 to hose main part 13 for a long time, with it is firm to realize the hose nipple riveting, it is not hard up, do not rotate, and protective sheath 14 riveting back, need to paste flat hose, can not have the effect of obvious step. The necking machine is the prior art and will not be described herein.

Referring to fig. 2, in the embodiment, a pull-out faucet includes a faucet body 20, a spray head 30 and the pull-out hose 10, wherein the spray head 30 is connected to one end of the pull-out hose 10, and the pull-out hose 10 can be pulled out or retracted from one end of the faucet body 20. The threaded joint 111 of the first joint 11 is communicated with a water outlet, and the ball joint 121 of the second joint 12 is communicated with the spray head 30. Wholly adopt such structure can prevent effectively that hose main part 13 among the pull formula tap from being damaged by the gravity hammer, effectively increase hose main part 13's life, though simple structure, the function is easy, convenient to use.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art.
