[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Referring to Figures 1 to 4, a connector for confined spaces includes an upper connector 1 and a water inlet pipe 2. The upper connector 1 has an installation channel 101 in the middle, and the water inlet pipe 2 is inserted into the installation channel 101. The upper part of the water inlet pipe 2 protrudes out of the installation channel 101, and a transverse branch pipe 3 is connected to the upper side wall. A pressure cap 4 is provided on the upper side of the water inlet pipe 2. The pressure cap 4 and the upper connector 1 form a detachable connection, and the water inlet pipe 2 is pressed into the installation channel 101 and secured by the pressure cap 4.

[0023] In this connector, the upper connector 1 adopts a flat design and the water inlet pipe 2 is fixed by the pressure cap 4. This eliminates the need for the traditional metal bracket structure, reduces the overall thickness of the upper connector 1, and lowers the processing cost of the upper connector 1. It can be used in special products, such as humidifiers or places with narrow structural space.

[0024] The transverse branch pipe 3 extends horizontally outward from the outer side of the upper connector 1, and the transverse branch pipe 3 abuts against the top surface of the upper connector 1; the upper connector 1 also supports the transverse branch pipe 3, which can improve the strength of the transverse branch pipe 3 and prevent the transverse branch pipe 3 from being damaged by external impact.

[0025] The top surface of the upper connector 1 has several lower connecting holes 102 along the outer periphery of the mounting channel 101. The outer periphery of the pressure cover 4 has an upper connecting hole 41 corresponding to the lower connecting holes 102. The pressure cover 4 is fastened to the upper connector 1 by passing screws 5 through the upper connecting hole 41 and the lower connecting hole 102. The pressure cover 4 is fixed by fastening, which is simple to install, easy to operate, and has high production efficiency.

[0026] The top of the water inlet pipe 2 is closed, and the cover of the pressure cap 4 is provided with a matching relief opening 42 corresponding to the top of the water inlet pipe 2; and the outer peripheral wall of the upper part of the water inlet pipe 2 extends with a pressure bearing ring 21, and the pressure cap 4 presses against the water inlet pipe 2 through the pressure bearing ring 21.

[0027] In other embodiments, the cap 4 can be directly pressed against the top of the water inlet pipe 2 to press the water inlet pipe 2 tightly. However, the cover surface of the cap 4 is superimposed on the top of the water inlet pipe 2, and the thickness of the cover surface always increases the thickness of the upper connector 1 to a certain extent. Therefore, in order to minimize the overall thickness of the upper connector 1, the clearance opening 42 on the cover surface is used to make the top of the water inlet pipe 2 protrude into the clearance opening 42 so that the cap 4 will not affect the height of the upper connector 1.

[0028] The top surface of the upper connector 1 extends along the outer periphery of the mounting channel 101 with a support ring portion 103 composed of a whole circle or multiple blocks. The pressure bearing ring portion 21 abuts against the support ring portion 103 and is clamped between the cover surface of the pressure cap 4 and the support ring portion 103.

[0029] The top surface of the upper connector 1 has a positioning protrusion 104 extending on the opposite side of the mounting channel 101, and the lower connecting hole 102 is opened on the positioning protrusion 104; the outer peripheral wall of the pressure cover 4 has a positioning sleeve 43 that fits onto the positioning protrusion 104, and the upper connecting hole 41 is opened on the positioning sleeve 43; the cooperation between the positioning protrusion 104 and the positioning sleeve 43 enables the pressure cover 4 to be installed on the top surface of the upper connector 1 with a foolproof function, and can maintain a stable position before screwing in the screw 5, which can improve assembly efficiency;

[0030] In addition, the upper connecting hole 41 is a countersunk hole; the countersunk hole can make the head of the screw 5 flush with or lower than the top surface of the cover 4. In addition to achieving the purpose of aesthetics and reducing protrusions, the most important thing is to avoid the head of the screw 5 protruding, which would increase the height of the upper connector 1.

[0031] The cover wall of the pressure cap 4 has a limiting opening 44 with a certain width. The transverse branch pipe 3 extends out of the outer side of the pressure cap 4 through the limiting opening 44 and swings left and right within the width range of the limiting opening 44. This allows the transverse branch pipe 3 to have a certain adjustment range, making the upper connector 1 more flexible during installation.

[0032] The top surface of the upper connector 1 also extends a left swing limiting plate 6 and a right swing limiting plate 7, and the transverse branch pipe 3 is limited between the left swing limiting plate 6 and the right swing limiting plate 7; the left swing limiting plate 6 and the right swing limiting plate 7 can prevent the transverse branch pipe 3 from swinging excessively.

[0033] The top surface of the upper connector 1 has a supporting rib 8 extending from the edge, and the outer end of the transverse branch pipe 3 abuts against the supporting rib 8; the supporting rib 8 has an arc-shaped structure and is concentrically arranged with the water inlet pipe 2; the length of the supporting rib 8 at least covers the left and right swing range of the transverse branch pipe 3.

[0034] During implementation, a certain width gap is actually left between the entire section of the transverse branch pipe 3 and the top surface of the upper connector 1. This gap is mainly used to avoid the rivet piece generated on the top surface when the conductive copper ring inside the upper connector 1 is connected. The height of the support rib 8 matches the gap, so that the outer end of the transverse branch pipe 3 has a support point, making it less likely to be crushed or deformed. The surface of the support rib 8 is arc-shaped, which can reduce friction with the transverse branch pipe 3.

[0035] The inlet pipe 2 is also equipped with a one-way valve core 9; the one-way valve core 9 includes a return spring 91, a steel ball 92 and a silicone anti-leakage sleeve 93 arranged from top to bottom, and the steel ball 92 is sealed against the silicone anti-leakage sleeve 93 by the return spring 91; so that the inlet pipe 2 has the function of preventing backflow.

[0036] In addition, the upper connector 1 includes an upper connector seat, which has a plug-in cavity. Multiple concentric but different diameter conductive copper rings are fixed on the plug-in cavity. Multiple terminal pieces are fixed on the top surface of the upper connector seat by screws. The conductive copper rings extend through the upper connector seat and have rivet pieces. The rivet pieces are electrically connected to the terminal pieces. The upper connector 1 with this structure belongs to the prior art and will not be described in detail here.

[0037] The above describes the preferred embodiments of this utility model, illustrating and describing its basic principles, main features, and advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
