Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to the present utility model are shown in the drawings, not all of the structures. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0022] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0023] like Figs. 1-4 As shown, this embodiment discloses a drainer, including a housing 1. The housing 1 has a water inlet chamber and a water inlet channel 111 and a drain channel communicating with the water inlet chamber. The draining mechanism 3 includes a float 31 and a flexible sealing strip 32. One end of the sealing strip 32 is fixed in the water inlet chamber, and the float 31 is fixed to the other end of the sealing strip 32. The end of the sealing strip 32 connected to the float 31 is a movable end. The drain channel is located below the sealing strip 32. In the first state, the sealing strip 32 is pressed down by the gravity of the float 31 to block the drain channel. In the second state, the float 31 drives the sealing strip 32 to swing or move upward under the action of buoyancy, so that the lower end face of the sealing strip 32 is separated from the drain channel, thereby opening the drain channel. The swing of the sealing strip 32 can be upward swinging with the left or right side in the water inlet chamber. It only requires a small buoyancy to make the sealing strip 32 tilt up a corner, so that the lower end face of the sealing strip 32 is separated from the drain channel to realize drainage. For better drainage and sealing, the sealing strip 32 can be made of rubber, and a silicone sleeve is fitted in the water inlet end of the drainage channel. The silicone sleeve is open from top to bottom, allowing condensate to flow from the silicone sleeve into the drainage channel, thereby achieving drainage.

[0024] The housing 1 includes a lower housing 12 and an upper housing 111 that is sealed and installed with the lower housing 12; the upper housing 111 is installed above the lower housing 12. The upper housing 111 and the lower housing 12 together form the aforementioned water inlet chamber. The water inlet channel 111 is provided in the upper housing 111, and the water outlet channel is provided in the lower housing 12 and located on the bottom surface of the lower housing 12. The upper housing 111 is also provided with at least one pressure relief port 112, which is used to install a pressure relief valve. The pressure relief valve is normally closed and can be opened to release pressure from the water inlet chamber as needed. The pressure relief port 112 can also be sealed with a sealing element / sealing plug.

[0025] The bottom of the water inlet chamber has a boss 121, and the sealing strip 32 and the drainage channel are set on the boss 121. One end of the drainage channel is connected to the water inlet chamber, and the other end extends to the bottom of the housing 1, so that condensate can be discharged to the drain. A silicone sleeve is set at the end of the drainage channel located in the water inlet chamber. Specifically, the boss 121 is set at the bottom of the lower housing 12. One end of the sealing strip 32 is a fixed end, and the other end is a movable end. The fixed end of the sealing strip 32 is fixed to the boss 121 by bolts, and the movable end of the sealing strip 32 is connected to the float 31. Normally, the float 31 and the sealing strip 32 can be fixed by bolts or by adhesive bonding. In this embodiment, the sealing strip 32 is fixed to the float 31 by bolts. The bolt passes through the sealing strip 32 from one end of the float 31 and is fixed by a nut. It can also be directly threaded to the sealing strip 32. For a more secure fixation, the bolt usually passes through the sealing strip 32.

[0026] The boss 121 includes a first boss 122 and a second boss 123, which are spaced apart and have the same horizontal height. A clearance groove 124 is formed between the first boss 122 and the second boss 123. The horizontal plane of the clearance groove 124 is lower than the plane of the boss 121, which provides clearance space for the bolt and prevents the bolt from abutting against the boss 121, thus preventing the sealing strip 32 from abutting against the silicone sleeve and causing a failure to seal. The fixed end of the sealing strip 32 is installed on the first boss 122, and the movable end of the sealing strip 32 abuts against the second boss 123 in the first state. Specifically, after the movable end of the sealing strip 32 is connected to the float 31, it also has an extension. The extension abuts against the second boss 123, so that the sealing strip 32 is stably positioned on the boss 121 to achieve a seal. The water outlet channel is set between the fixed end of the sealing strip 32 and the float 31.

[0027] A sedimentation tank 125 is formed at the bottom of the water inlet chamber between the bosses 121. Specifically, a sedimentation tank 125 is formed between the bosses 121 and the inner wall of the lower housing 1. The sedimentation tank 125 is mainly used to settle impurities in the condensate. A filter screen 2 is provided above the sedimentation tank 125, and the filter screen 2 abuts against the bosses 121. Specifically, the filter screen 2 has a relief opening 22 in the middle that matches the shape of the bosses 121, so that the filter screen 2 can be fitted onto the bosses 121 and abut against them. One side of the filter screen 2 has a water inlet notch 21 that matches the water inlet channel 111, so that the condensate in the water inlet channel 111 enters the sedimentation tank 125 through the water inlet notch 21, and then the filter screen 2 filters the impurities in the condensate into the sedimentation tank 125. Preferably, a drain port communicating with the sedimentation tank 125 is provided at the bottom of the lower housing 1, and the impurities in the sedimentation tank 125 are discharged through the drain port. The filter screen 2 can be fixed by abutting against the boss 121, by setting an installation groove in the lower housing 12, or by clamping the lower housing 12 and the upper housing 111.

[0028] The upper housing 111 includes a partition that divides the upper housing 111 into a water inlet channel 111 and a water inlet chamber. When the upper housing 111 is fixed to the lower housing 12, the water inlet channel 111 is connected to the water inlet notch 21 of the filter screen 2. This allows condensate to enter the sedimentation tank 125 through the water inlet channel 111, be filtered by the filter screen 2, and then enter the water inlet chamber, thereby pushing the float 31 to drain water. The partition is integrally formed with the upper housing 111 and includes a horizontal plate and a vertical plate. The vertical plate divides the interior of the upper housing 111 to form the water inlet channel 111, and the horizontal plate divides the water inlet channel 111 into two sections. The water inlet notch 21 of the filter screen 2 is also correspondingly set to be two sections.

[0029] The float 31 is elliptical in shape, which increases the contact surface at its bottom and thus increases its buoyancy. To prevent the float 31 from swinging too much under the buoyancy of the condensate, a series of limiting ribs 113 are provided on the inner wall of the water inlet cavity of the upper shell 111. The swing amplitude of the float 31 is limited by the limiting ribs 113, which are arranged in an array.

[0030] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
