[0013] The beneficial effects of the utility model are as follows:

[0014] 1. Under normal circumstances, condensate flows from the water inlet along the first chamber, passes through the filter at the bottom of the first chamber, and enters the second chamber. The drain assembly is then opened for drainage. However, condensate often enters the drain along with industrial grease. Grease has a lower density than water, so it floats on the condensate. Grease adheres to the filter, which over time can easily form a water seal at the filter. However, the amount of condensate in the drain continues to increase, preventing communication between the first and second chambers. This creates a pressure imbalance between the first and second chambers and can lead to drain failure. By providing a connecting channel in the middle or upper portions of the first and second chambers, air can flow between the two chambers, thereby balancing the pressures. When the water level in the first chamber reaches the level of the connecting channel, it can flow into the second chamber, allowing the drain assembly to open for drainage.

[0022] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments.

[0023] Example 1

[0024] like Figures 1 to 4 As shown, this embodiment discloses a drainer, comprising a housing 1, the interior of which is divided into a relatively independent first space 112 and a second space 3. The first space 112 is at least partially located at the bottom of the second space 3 and communicates with the second space 3. A filter 4 is provided at the connection between the first space 112 and the second space 3 to prevent impurities from entering the second space 3. A connecting channel 116 is also provided in the middle or upper portion of the first space 112 and the second space 3, allowing air or condensed water in the first space 112 and the second space 3 to circulate. This prevents condensed water from entering the second space 3 when a water seal is encountered, resulting in a pressure imbalance between the first space 112 and the second space 3 and causing a malfunction. The drainer can effectively stabilize pressure.

[0025] The housing 1 is provided with a water inlet 111, a drain outlet, and a sewage outlet 121. The water inlet 111 is located on the sidewall of the first space 112, in the upper middle portion, and extends through the housing 1. The sewage outlet 121 is located in the first space 112, below the water inlet 111. The sewage outlet 121 can be located on the sidewall or bottom of the housing 1, depending on actual needs. The drain outlet is located within the second space 3 and is used to drain condensed water within the second space 3 out of the drain.

[0026] In order to facilitate the installation of the drain assembly 5 of the drain, the shell 1 includes an upper shell seat 11 and a lower shell seat 12 sealed therewith; a baffle 115 is provided inside the shell 1, and the baffle 115 divides the interior of the shell 1 into a first space 112 and a second space 3; the specific partition is provided on the upper shell seat 11 and is flush with the bottom of the upper shell seat 11. The water inlet 111 is provided on the upper shell seat 11, and the sewage outlet 121 and the drain outlet are provided on the lower shell seat 12. The lower shell seat 12 is installed below the upper shell seat 11, and it has a water passage for the flow of condensed water, and a sewage collecting trough 2 is formed at the bottom, and the sewage collecting trough 2 is arranged at an angle. The end close to the sewage outlet 121 is lower than the end away from the sewage outlet 121. Specifically, the end close to the second space 3 is higher than the other end.

[0027] Connecting channel 116 is disposed in the middle or upper portion of baffle 115. Preferably, baffle 115 and upper housing 11 are integrally formed, and connecting channel 116 is disposed on the top inner wall of housing 1. Connecting channel 116 is semicircular in shape and opens downward, with its ends connecting first space 112 and second space 3, respectively. The circular shape and location of connecting channel 116 on the top inner wall of housing 1 primarily facilitate gas circulation, reducing the flow of unfiltered condensate into second space 3. However, if the drainer's outlet seal is compromised and a malfunction is suspected, the water level in first space 112 may exceed normal levels and flow into second space 3 through connecting channel 116.

[0028] The drainage component 5 is arranged in the second space 3. The drainage component 5 moves from the first position to the second position under the buoyancy. In the first position, the drainage component 5 closes the drain outlet. In the second position, the drainage component 5 opens the drain outlet due to the floating buoyancy.

[0029] Specifically, the drain assembly 5 includes a lever mechanism 51 and a float 514 blocking portion 52. The lever mechanism 51 is installed in the second space 3, one end of which is connected to the float 514 blocking portion 52, and the other end has a blocking member. The blocking member is located above the drain outlet. The lever mechanism 51 drives the blocking member to open or close the drain outlet through the buoyancy of the float 514 blocking portion 52. The lever mechanism 51 includes a mounting seat 511 and a lever. The mounting seat 511 is installed in the second space 3, and its upper end has a hinged portion 512. A rocker 513 is installed at one end on the hinged portion 512 and at the other end connected to the float 514 blocking portion 52. The blocking member is located on the rocker 513 and opens or closes the drain outlet through the buoyancy of the float 514 blocking portion 52.

[0030] When the drain assembly 5 is in the first position, the condensate level in the second space 3 is lower than the position of the drain assembly in the second space 3. Specifically, the condensate level in the second space 3 is lower than the position of the blocking portion 52 of the float 514 in the second space 3. At this time, the blocking portion 52 of the float 514 closes the drain outlet, and the drain does not drain water. As the condensate level in the second space 3 gradually rises, the condensate lifts the blocking portion 52 of the float 514 through buoyancy, which in turn drives the seesaw 513 to rotate along the hinge 512, causing the blocking portion to move away from the drain outlet, thereby opening the drain outlet and allowing water to drain. At this time, the blocking portion 52 of the float 514 reaches the second position.

[0031] To ensure a better seal and prevent gas leakage within the drain, a rubber sleeve is installed at the drain outlet. The sleeve runs vertically through the drain outlet, forming a drainage channel 114 for drainage. The sealing member opens or closes drainage channel 114 as the float 514 seals the sealing portion 52. The sealing portion is tapered at one end of the rubber sleeve corresponding to drainage channel 114, which effectively seals drainage channel 114 and prevents gas leakage.

[0032] In order to facilitate observation of the internal operation of the drainer, a perspective window 113 is further provided on the side wall of the shell 1 . The perspective window 113 is located on the side wall of the second space 3 .

[0033] Working principle:

[0034] During normal operation of the drain, condensed water flows from the water inlet 111 into the first space 112 and then from the bottom of the first space 112 through the filter 4 into the second space 3. The filter 4 filters out most impurities and grease that would otherwise adhere to the filter 4. As more condensed water enters the second space 3, the water level gradually rises and, through buoyancy, lifts the sealing portion of the float 514; 52, the float 514 floats upward and lifts the sealing portion through the hinge 512 of the rocker 513, thereby opening the drain outlet.

[0035] Over time, the increasing amount of grease adhering to the filter 4 can easily cause a water seal to form inside the drain. Condensate cannot enter the second space 3 and accumulates in the first space 112. The condensate level gradually rises, causing the air in the first space 112 to gradually flow through the connecting channel into the second space 3. This prevents malfunctions caused by a pressure imbalance between the first space 112 and the second space 3 caused by the squeeze of the condensate. When the water level reaches the connecting channel, the condensate can also flow into the second space 3 through the connecting channel. When the water level in the second space reaches a certain height, the buoyancy of the float 514 seals the drain port, opening the drain and allowing the water to drain.

[0036] Example 2:

[0037] The difference between Example 2 and Example 1 lies in the additional inclusion of a liquid level sensor and a control module, and the installation of an electromagnetic drain valve at the drain outlet 121. The control module controls the opening and closing of the electromagnetic drain valve by receiving signals from the liquid level sensor. Specifically, the liquid level sensor is located within the first space 112 and is used to detect the level of condensate within the first space 112. When the liquid level sensor detects that the water level has reached a first preset value, it feeds a signal back to the control module, which controls the opening of the electromagnetic drain valve. When the liquid level sensor detects that the water level has reached a second preset value, it feeds a signal back to the control module, which controls the closing of the drain valve. The first preset value is higher than the second preset value. Promptly draining the condensate within the first space 112 effectively prevents malfunction of the drainer. When the water level in the first space 112 is too high, draining the condensate through the electromagnetic drain valve achieves the effect of draining without exhausting the condensate. Furthermore, the sump 2 is provided with an inclined surface, so that impurities are primarily deposited on the side near the drain outlet 121. This allows the impurities to be simultaneously discharged from the drainer while draining the condensate, eliminating the need for secondary impurity removal.
