Hose connector with an adjustment structure

A hose connector with at least one adjustment structure, comprising:

• a sidewall configured to encircle and form a first connector end and a second connector end and provided with an interior and an exterior, with the exterior having a gripping portion;
• wherein the first connector end, configured to connect to an external tubular connector, includes a chamber to house the external tubular connector, an opening to allow the external tubular connector to enter the chamber, and a retaining structure to enhance fixation ability;
• wherein the second connector end, configured to connect to a hose, includes a space to accommodate the hose;
• wherein the at least one adjustment structure is provided in the sidewall along the opening;
• wherein the first connector end is made of a resilient first material, a hardness of the first material is between Shore A 30 to Shore A 70;
• and
• wherein the retaining structure has one or more of the following characteristics:
• a. having an inner diameter less than or equal to an outer diameter of the external tubular connector;
• b. protruding toward a central axis of the hose connector;
• c. being in an inverted cone shape;
• d. a material of the retaining structure being a second material,
• wherein the at least one adjustment structure has a third material different from the first material such that the first connector end is configured to elastically deform when connecting to the external tubular connector by causing stress concentration at the at least one adjustment structure,
• wherein the third material has a hardness that is less than the hardness of the first material and is between Shore A 20 and Shore A 40.

A hose connector with at least one adjustment structure, comprising:

• a sidewall configured to encircle and form a first connector end and a second connector end and provided with an interior and an exterior, with the exterior having a gripping portion;
• wherein the first connector end, configured to connect to an external tubular connector, includes a chamber to house the external tubular connector, an opening to allow the external tubular connector to enter the chamber, and an abutment surface to limit a displacement of the external tubular connector;
• wherein the second connector end, configured to connect to a hose, includes a space to accommodate the hose;
• wherein the at least one adjustment structure is provided in the sidewall along the opening;
• wherein the first connector end is made of a resilient first material, a hardness of the first material is between Shore A 30 to Shore A 70;
• wherein an inner diameter of the second connector end is less than or equal to an inner diameter of the first connector end;
• and
• wherein a depth of the chamber is at least 12 mm,
• wherein the at least one adjustment structure has a third material different from the first material such that the first connector end is configured to elastically deform when connecting to the external tubular connector by causing stress concentration at the at least one adjustment structure,
• wherein the third material has a hardness that is less than the hardness of the first material and is between Shore A 20 and Shore A 40.

• and
• wherein the at least one adjustment structure has the following characteristics:
• a. having a depth not exceeding ½ of a depth of the chamber;
• b. having a width less than ⅔ of an inner diameter of the opening of the first connector end,
• wherein the at least one adjustment structure has a third material different from the first material such that the first connector end is configured to elastically deform when connecting to the external tubular connector by causing stress concentration at the at least one adjustment structure,
• wherein the third material has a hardness that is less than the hardness of the first material and is between Shore A 20 and Shore A 40.
