Abstract: A hose is provided by the present invention. The hose includes a nut cap and a hose member with two openings on both ends thereof. On at least one end of the hose member is disposed an outer sleeve and an inner metal sleeve. In which, the outer sleeve sleeves around an outer periphery of the hose member, and one end thereof proximate to the opening is radially and outwardly extended a first rim. Moreover, the inner metal sleeve has an initial outer diameter smaller than a bore diameter of the hose member so as to be installed therein, and the inner metal sleeve is then enlarged in a stamping manner to form an enlarged section, such that the hose member is tightly gripped between the outer and inner metal sleeves. Thereby, the hose member, the outer and inner metal sleeves are tightly fastened up, and the bore diameter of the opening of the hose is close to, or even equal to, that of the hose member.

Abstract: A gas injection device is provided. A separation plate is disposed between inlet and outlet ends of a main body. At least one flow hole is disposed around a through hole of the separation plate. Top, middle and bottom sections of a valve body are disposed respectively at the inlet end, through the through hole and at the outlet end. Respective outer diameters of the top and bottom sections are larger than an inner diameter of the through hole, and the largest outer diameter of the bottom section is larger than a smallest inner diameter of the outlet end. A length of the middle section is longer than an axial length of the through hole. An elastic member through the middle section abuts against the separation plate and the bottom section to bias the valve body toward the outlet end and normally unclose the bottom section.

Abstract: A hose is provided by the present invention. The hose includes a nut cap, a plastic hose and a metal spiral hose. On at least one end of the metal spiral hose is disposed an outer sleeve and an inner metal sleeve. In which, the inner metal sleeve has an initial outer diameter smaller than a bore diameter of the metal spiral hose so as to be installed therein, and the inner metal sleeve is then enlarged in a stamping manner to form an enlarged section, such that the metal spiral hose is tightly gripped between the outer and inner metal sleeves. The plastic hose is disposed in the metal spiral hose, and on at least one end of the plastic hose is disposed a positioning sleeve, so that the plastic hose is positioned between the inner metal sleeve and the positioning sleeve.

Abstract: A fluid mixing device includes a body, a water controlling valve assembly and a Venturi tube structure. The body is internally formed with inlet channels for communicating with water source, a first channel, an outlet channel communicating between the first channel and outside of the body, and a gassing channel communicating between the first channel and a gas source. The water controlling valve is operable between first and second positions. The Venturi tube structure is disposed within the first channel and includes a necked passage communicating with the first channel and a gassing hole communicating between the necked passage and the gassing channel. When the water controlling valve is located in the first position, the water flow passes through the necked passage and draws gas from the gas source through the gassing hole to come into the necked passage to mix with each other.

Abstract: A portable bidet sprayer comprises a container, a pressure element, a fixation mechanism, and a spraying device. The container has a receiving space. The pressure element comprises a first end and a second end. The pressure element is able to move upwards and downwards between a first position and a second position with respect to the container. The pressure element is selectively fixed in the second position by the fixation mechanism. The spraying device is disposed in the container. Whereby, the first end of the pressure element does not protrude from the container too much, so the portable bidet sprayer is convenient to be taken with users. After bowel movement, users can rinse their anuses manually by the portable bidet sprayer.
