In the following, specific embodiments of the present invention will be described in more detail with reference to the accompanying drawings, which illustrate representative embodiments of the invention and do not limit the invention.

As shown in fig. 1 to 3, the present invention provides a water drainer 100, the drainer 100 being mountable to a floor 10 of a refrigerated container.

The water leak 100 includes a cartridge 110, a plug 120, a float assembly 130, and a base 140. The barrel 110 has a top opening 111 (fig. 2), and the float ball assembly 130 is received within the barrel 110 via the top opening 111. The plug 120 can be removably disposed at the top opening 111 and seal the top opening 111. The base 140 has a receiving portion with an opening facing upward, and the cylinder 110 is received in the receiving portion. The bottom of the base 140 is provided with an opening. The base 140 is used to connect with the floor 10.

The above-mentioned components of the water drainer 100 are described in detail below with reference to the accompanying drawings.

As shown in fig. 1 and 2, the cylinder 110 has a transversely extending bottom wall 112 and a vertically extending side wall 113, the side wall 113 can be connected to the bottom wall 112, and the bottom wall 112 is provided with a first diversion hole 101. The number of the first guide holes 101 is not limited. Alternatively, the cylinder 110 may be made of a metal material such as aluminum. The stopper 120 may be inserted into the top of the barrel 110 through the top opening 111 or withdrawn from the barrel 110. The float ball assembly 130 is movably disposed within the barrel 110. The float assembly 130 can be in a first position (fig. 1) abutting the plug 120 when the plug 120 seals the top opening 111. When the plug 120 is removed, the float assembly 130 is in a second position (fig. 2) within the top opening 111 and not beyond the top opening 111. The float ball assembly 130 is movable between a first position and a second position.

In this embodiment, the position of the float assembly 130 in the cylinder 110 is adjustable up and down, and the adjustment of the position enables the water leakage device 100 to have both the function of automatic water leakage and good sealing performance. When the plug 120 is pulled out, the float ball assembly 130 can move upwards but not exceed the top opening 111, so that a large amount of impurities in the tank can not be accumulated above the float ball assembly 130 to cause blockage in the process of draining, and automatic water leakage can be realized. When the plug 120 is inserted, the float assembly 130 can move downward so that the plug 120 completely plugs the top opening 111, and thus the plug 120 can block the inside of the refrigerated container from the external environment without communicating with the outside environment, thereby preventing cold air from escaping and ensuring the sealing performance inside the refrigerated container.

Further, the float assembly 130 may include an upper chamber 131 at an upper portion, a lower chamber 132 at a lower portion, and a partition 133 extending in a lateral direction of the barrel 110. The upper chamber 131 is located above the lower chamber 132. An upper float ball 134 is received in the upper chamber 131. Lower float ball 135 is contained within lower chamber 132. A partition 133 is located between the upper chamber 131 and the lower chamber 132 to partition the upper chamber 131 and the lower chamber 132. The first wall 136 of the upper chamber 131 extends vertically and is connected to the partition 133. The first wall 136 may be spaced apart from the sidewall 113 of the barrel 110. The top of the upper chamber 131 is provided with a screen 137.

It will be appreciated that directional terms used herein in describing the water leakage 100, such as "upper", "lower", "upward", "downward", "above", "below", "vertical", "lateral", etc., are with respect to the water leakage 100 in a vertical disposition (in an installed condition).

The second wall 138 of the lower chamber 132 extends vertically with its upper end connected to the partition 133 and its lower end connected to the third wall 139. The third wall 139 is provided with an opening. The second wall 138 of the lower chamber 132 may be spaced apart from the sidewall 113 of the barrel 110. The partition 133 is provided with the second guide hole 102. One of the second flow guide holes 102 is shown and is located at the center of the partition 133. The upper chamber 131 communicates with the lower chamber 132 via the second pilot holes 102. The first wall 136 and the second wall 138 may each be provided with a through hole to facilitate communication inside the cylinder 110.

The water drain 100 further comprises a resilient element 150. The elastic member 150 may be disposed between the bottom wall 112 and the float assembly 130, one end of the elastic member 150 may abut or be connected to a lower portion of the float assembly 130, and the other end of the elastic member 150 opposite to the one end abuts or is connected to the bottom wall 112. In the illustrated embodiment, one end of the elastic element 150 can be sleeved on the second wall 138 of the lower chamber 132, and the other end of the elastic element 150 abuts against or is connected to the bottom wall 112. The resilient member 150 is sized to fit against the second wall 138. Optionally, the resilient element 150 is a spring. Of course, the resilient member 150 can be other suitable members if needed and/or desired.

Resilient member 150 is capable of biasing ball assembly 130 upward to move ball assembly 130 from the first position to the second position. In a state where the stopper 120 is inserted into the cylinder 110, the elastic member 150 is in a compressed state. After the stopper 120 is pulled out, the elastic member 150 elastically springs the floating ball assembly 130 upward by itself. Specifically, resilient member 150 is configured to maintain buoyant ball assembly 130 in the second position. The resilient force of the resilient member 150 is just enough to move the float assembly 130 upward to the second position without providing another stop on the barrel 110. In this embodiment, removal of the float assembly 130 as a whole from the barrel 110 for replacement or repair may be facilitated.

Of course, other stops may be provided on the barrel 110 that are capable of stopping movement of the float assembly 130 when the float assembly 130 is moved to the second position, if needed and/or desired. Alternatively, the blocking member may be movable between a position to block movement of the float ball assembly 130 and a position to allow removal of the float ball assembly 130.

In this embodiment, the float assembly 130 is adjustable up and down by the action of the plug 120 and the resilient member 150.

The partition 133 protrudes from the upper and

lower chambers

131 and 132. The spacer 133 may be sleeved with a sealing ring 160. The seal ring 160 can abut against the side wall 113 of the cylinder 110. For example, the partition 133 may be provided with a circumferentially extending groove 103, with a portion of the sealing ring 160 received in the groove 103 and another portion protruding out of the groove 103 and abutting the sidewall 113. Thus, the packing 160 may seal the upper and lower spaces inside the cylinder 110 partitioned by the partition 133. Also, the seal ring 160 can slide on the side wall 113 when the float assembly 130 moves, so that when the float assembly 130 moves upward, a frictional force opposing the elastic force of the elastic member 150 can be generated between the seal ring 160 and the side wall 113, which can prevent the float assembly 130 from popping up suddenly and beyond the top opening 111.

Specifically, the resilient member 150 and the sealing ring 160 act to enable the top surface of the float assembly 130 in the second position to be below the top surface of the cartridge body 110 or flush with the top surface of the cartridge body 110. The stopper 120 can be interference fitted with the barrel 110, alternatively, the stopper 120 and the barrel 110 may be provided with threads fitted to each other to be connected by threads.

As shown in fig. 3, to facilitate mounting of the water drainer 100 to the floor 10 of a refrigerated container, the barrel 110 may be removably mounted to the base 140. The base 140 may be provided with an outwardly extending flange 141, the flange 141 having a mounting hole 142 for connection with the floor 10 of the container. In the installed state, the flange 141 is located below the floor panel 10, and a fastener such as a screw or the like may be inserted into the floor panel 10 via the installation hole 142, resulting in fixation of the base 140.
