UTILITY MODEL CONTENTS

[0005] The utility model aims at the above problems existing in the prior art, and provides a quick connector of a foam sprayer, and the technical problem to be solved by the utility model is how to improve the convenience of connector replacement.

[0006] The utility model can be realized by the following technical scheme.

[0007] A quick connector of a foam sprayer, comprising a connector body made of metal, characterized in that the quick connector further comprises a plastic piece sleeved on the connector body, the plastic piece is formed on the connector body, the plastic piece is annular, and a plurality of protrusions are arranged on the outer circumferential surface of the plastic piece in a circumferential direction.

[0008] The quick connector is manufactured by embedding the connector body into a mold together with a plastic part, and the plastic part is firmly connected to the connector body. The plastic part increases the size of the connector body, and the weight of the plastic part is light, so that the size of the connector body is increased without significantly increasing the weight of the connector body. When the connector body is replaced, the user can hold the plastic part conveniently. A plurality of protrusions are arranged on the outer circumferential surface of the plastic part in a circumferential direction, so that the friction between the plastic part and the hand is increased, the plastic part is not easy to slip when it is rotated, and the plastic part is easy to rotate, thereby ensuring that the connector body is disassembled or assembled conveniently.

[0009] In the quick connector of the foam sprayer, the middle part of the connector body has two connecting flanges, and a groove is arranged between the two connecting flanges. The plastic part is formed on the middle part of the connector body and wraps the two connecting flanges, and the plastic part has a connecting part extending into the groove. The plastic part is formed on the middle part of the connector body and wraps the two connecting flanges, and the plastic part has a connecting part extending into the groove. This structure makes the connection between the plastic part and the connector body firm, and the plastic part is not easy to fall off. When the plastic part is rotated, the connection between the plastic part and the connector body can withstand a large stress and will not break.

[0010] In the quick connector of the foam sprayer, each connecting flange is a regular hexagon. This structure further improves the connection strength between the plastic part and the connector body.

[0011] In the quick connector of the foam sprayer, an outer thread is arranged on the outer circumferential surface of the rear end of the connector body. The plastic part has a housing part surrounding the rear end of the connector body. An annular accommodating cavity is formed between the inner circumferential surface of the housing part and the outer circumferential surface of the rear end of the connector body. The rear end of the connector body is used to be screwed with the valve body of the foam sprayer. The connecting port on the valve body is conveniently extended into the accommodating cavity. The housing part surrounds the connecting port on the valve body, and the stability of the connection between the connector body and the valve body is improved.

[0012] In the quick connector of the foam sprayer, a weight-reducing groove in the shape of a ring is arranged on the front end surface of the plastic part, and the weight-reducing groove extends along the axial direction of the connector body to the rear end of the plastic part. A reinforcing rib is arranged in the weight-reducing groove, and the reinforcing rib has a plurality of reinforcing ribs arranged in a circumferential direction. The design of the weight-reducing groove further reduces the weight of the plastic part, thereby reducing the manufacturing cost of the plastic part. The arrangement of the reinforcing rib improves the structural strength of the plastic part, so that the plastic part will not be broken when it is rotated.

[0013] Compared with the prior art, the quick connector of the foam sprayer of the present invention has the following advantages: during the production process of the quick connector, the connector body is made from a mold together with the plastic part in the form of an insert, and the connection between the plastic part and the connector body is relatively firm. The setting of the plastic part is equivalent to increasing the size of the connector body. Since the plastic part is light in weight, the size of the connector body is significantly increased without significantly increasing the weight of the connector body, which is convenient for the user to hold when replacing the connector body. Several protrusions are arranged at circumferential intervals on the outer peripheral surface of the plastic part, which increases the friction between the plastic part and the hand grip, making it less likely to slip when rotating the plastic part, ensuring that it is more labor-saving in the process of twisting the plastic part. The plastic part drives the connector body to rotate, thereby realizing the disassembly or installation of the connector body, and significantly improving the convenience of replacing the connector body.
