DETAILED DESCRIPTION

[0021] Example embodiments now will be described more fully hereinafter with reference to the accompanying drawings; however, these embodiments should not be construed as limiting all example embodiments. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of example embodiments to those skilled in the art. In the drawings, the thickness of regions and layers can be exaggerated for clarity. Like reference numerals in different drawings denote like elements, and thus their detailed descriptions can be omitted.

[0022] The described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the present application. One skilled in the relevant art will recognize, however, that the application can be practiced without one or more of the specific details, or with other methods, components, materials, etc. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring aspects of the application.

[0023] The following examples describe dispensers of the present application, and are only a part of the embodiments of the present application, but the protection scope of the present application is not limited thereto. All other embodiments obtained by those skilled in the art without creative labor should be covered in the protection scope of the present application.

[0024] Please refer to Figures 1 to 5 According to the first embodiment of the present application, a dispenser is provided, comprising a dispenser body, the dispenser body comprising a liquid inlet part 1, a transition part 2 and a liquid outlet part 3, the liquid inlet part being provided with a liquid inlet channel 11, the dispenser body being integrally formed; a variable-diameter transition part 2 is arranged between the liquid inlet part 1 and the liquid outlet part 3, the transition part being internally hollow; the liquid outlet part is generally cylindrical, and the liquid outlet part is uniformly provided with three liquid outlet holes 31 along the circumference; a spinning throttling part 4 is arranged between the liquid inlet part and the transition part, and the inner end face of the liquid outlet part is protrusively provided with a flow splitting cone 5.

[0025] The liquid outlet part is locally concave between adjacent liquid outlet holes to form an inner concave part 32, and the inner concave part only penetrates the outer end face 33 of the liquid outlet part. According to the technical solution, the liquid outlet part is locally concave between adjacent liquid outlet holes, which reduces the use of the material of the dispenser body and lowers the cost of the dispenser. In addition, the inner concave part is only locally concave, and the circumferential face 34 of the liquid outlet part is retained, and when the inner concave part only penetrates the outer end face of the liquid outlet part, part of the complete circumferential face is retained, which facilitates clamping and processing of the transition part and the liquid inlet part after clamping by a clamp. The dispenser body can be integrally formed with the inner concave part by extrusion, without increasing the cost.

[0026] In the embodiment, the distance H between the axial bottom face 321 of the inner concave part and the inner end face 35 of the liquid outlet part is greater than or equal to the wall thickness L of the transition part, the axial bottom face 321 of the inner concave part and the radial concave face 322 of the liquid outlet part are smoothly connected, the strength and rigidity of the liquid outlet part are ensured, the deformation amount of the liquid outlet part when clamped by a clamp is reduced, and thus the processing quality of the transition part and the liquid inlet part is ensured. H is recommended to be not less than 1.5 mm, and preferably to be more than 2 mm, and L is recommended to be not less than 1 mm.

[0027] The inner recess is in the shape of an equal-diameter circular arc 323 in axial projection, and smoothly transitions between the equal-diameter circular arc and the circumference of the liquid outlet portion, with a smooth transition corner between the equal-diameter circular arc and the circumference of the liquid outlet portion not greater than 1.5 mm, and a longer circumferential surface of the liquid outlet portion is reserved to increase the clamping surface of the clamp. In addition, the equal-diameter circular arc can be further used to clamp the tool, and the tool corresponding to the equal-diameter circular arc is also an equal-diameter circular arc, which facilitates the machining of the tool.

[0028] In addition, the ratio between the minimum distance a between the inner wall surface of the liquid outlet hole and the circumferential surface of the liquid outlet portion and the minimum distance b between the inner wall surface of the liquid outlet hole and the wall surface of the inner recess is between 0.8 and 1.2, the wall thickness difference is small, the strength and rigidity of the liquid outlet hole are ensured, and the liquid outlet hole is prevented from being deformed when clamped by the clamp. The a is generally not less than 1.5 mm, and the b is generally between 1.2 and 1.8 mm.
