[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. It is understandable that the specific embodiments described herein are only used to explain the utility model, rather than to limit the utility model. It should also be noted that, for ease of description, only the parts related to the utility model rather than all structures are shown in the drawings. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0029] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0030] like Figure 1 to Figure 7 As shown, the utility model discloses an automatic drain, including a housing 1, a float 4, a pre-filter 2 and a filter assembly 6; the housing 1 is provided with a water space 122 and a water inlet channel 111 and a drainage channel 121 connected to the water space 122; the water inlet channel 111 is arranged at the top of the housing 1, and the drainage channel 121 is arranged at the side wall of the housing 1 and is located in the middle of the housing 1. The float 4 is located in the water space 122, and the diameter of the float 4 is smaller than the diameter of the water space 122, or smaller than the minimum spacing of the water space 122; the float 4 can open and close the drainage channel 121 by the buoyancy of condensed water. When the height of the condensed water in the water space 122 exceeds the position of the float 4 in the water space 122, the buoyancy of the condensed water lifts the float 4 and opens the water passage 51; when the height of the condensed water is lower than the position of the float 4 in the water space 122, the float 4 closes the water passage 51 again under the condition of gravity.

[0031] The pre-filter 2 is obliquely arranged on the upper part of the shell base 1 and is connected with the water inlet channel 111. Since the pre-filter 2 is obliquely arranged on the shell base 1, the condensed water will first enter the pre-filter 2 after passing through the water inlet channel 111, and the impurities in the condensed water will be precipitated in the pre-filter 2. A ball valve is provided at the outlet of the pre-filter 2 to facilitate the discharge of impurities, and a perspective window 21 is provided on the top of the pre-filter 2, so that the precipitation of impurities can be conveniently checked through the perspective window 21, and timely processing can be carried out.

[0032] The water inlet channel 111 includes a first channel 1111 and a second channel 1112 which are interconnected. The first channel 1111 is perpendicular to the horizontal plane, the second channel 1112 is inclined to the first channel 1111, and the second channel 1112 at least partially blocks the inlet 1221 of the water flow space 122 to prevent condensed water from directly entering the water flow space 122 after passing through the second channel 1112. Specifically, the second channel 1112 and the first channel 1111 are both circular channels, and the connection angle a between the axis of the second channel 1112 and the axis of the first channel 1111 is an obtuse angle.

[0033] The filter assembly 6 is disposed in the pre-filter 2 or the water inlet channel 111 . Preferably, in this embodiment, the filter assembly 6 is disposed in the pre-filter 2 and blocks the inlet 1221 of the water flow space 122 to filter the condensed water impurities entering the water flow space 122 .

[0034] In order to facilitate the disassembly and cleaning of the filter assembly. The filter assembly is detachably arranged in the water inlet channel 111 or the pre-filter 2. Preferably, the filter assembly is arranged in the pre-filter 2. Specifically, the filter assembly 6 includes a filter and a filter operating part 61 connected to the filter. A plug interface is provided on the side wall of the pre-filter 2, and the filter assembly 6 is sealedly installed on the filter along the plug interface; that is, by pushing the operating part, the filter is inserted into the pre-filter 2 through the plug interface, and the inlet 1221 of the water space 122 is blocked; the shape of the operating part is suitable for matching the shape of the plug interface. In order to facilitate the disassembly of the filter assembly 6, there is a disassembly port (not marked) connected to the plug interface next to the plug interface, which is convenient for removing the operating part from the plug interface.

[0035] Since flushing through the faucet may cause running water to flow into the water space 122, a baffle 7 may be provided to shield the inlet 1221 of the water space 122. Specifically, a baffle 7 socket is provided in the pre-filter 2. The baffle 7 is inserted into the pre-filter 2 through the socket and is sealed and connected to the inner wall of the pre-filter 2. Rubber strips are provided around the baffle 7 to better seal. The plug-in principle is equivalent to that of the filter assembly 6 and will not be described here. Two baffles 7 are usually used, one long and one short. When cleaning is not required, the short baffle 7 is used. The short baffle 7 will not shield the inlet 1221 of the water assembly and will not affect normal use.

[0036] In order to facilitate disassembly and maintenance, the housing base 1 includes an upper housing 11 and a lower housing 12 detachably connected to the upper housing 11. The water inlet channel 111 is arranged on the upper housing 11. The upper housing 11 and the pre-filter 2 are integrally formed to simplify the structure and facilitate assembly. The upper housing 11 and the lower housing 12 are covered to form the above-mentioned water flow space 122, and the drainage channel 121 is arranged on the lower housing 12.

[0037] At least two support columns 123 with inclined surfaces are provided on the inner wall of the lower shell 12, and the drain outlet is provided in one of the support columns 123. The float 4 is located in the water flow space 122. In the first state, the float 4 abuts against the two support columns 123 and blocks the drain outlet. In the second state, the float 4 is away from the two support columns 123 and opens the drain outlet. The diameter of the float 4 is smaller than the diameter of the water flow space 122. In this embodiment, preferably, the number of the support columns 123 is three, and the three support columns 123 are arranged circumferentially, that is, the three support columns 123 are evenly distributed on the inner wall of the water flow space 122, and the angle between two adjacent support columns 123 is 120°. The cross-section of the support column 123 is a triangle, and two of the corners of the triangle are connected to the inner wall of the shell, and the triangle presents an inclined surface that is inclined downward as a whole.

[0038] Usually, the shell 1 of the drainer is made of metal, mostly stainless steel. The shell 1 made of metal cannot fit better with the float 4, and its sealing is poor, and there may be a small amount of air leakage / liquid leakage; therefore, it is preferred to set a rubber water jacket 5 at the drain outlet, the end of the rubber water jacket 5 protrudes from the inside of the shell, and a water passage 51 is provided in the middle. Specifically, the rubber water jacket 5 is at least flush with the inclined surface of the support column 123 or slightly protrudes from the inclined surface of the support column 123, so that the float 4 can close the water passage 51 of the rubber jacket when it is subjected to gravity.

[0039] It also includes a manual drainage mechanism, which is located above the drain outlet. The manual drainage mechanism includes a through hole and a push rod mechanism 3 arranged on the side wall of the shell. The push rod mechanism 3 is installed in the through hole to push the float 4 to transform it from the first state to the second state, so as to avoid the drainer malfunctioning and the float 4 being unable to float up to open the drainage channel 121.

[0040] The push rod mechanism 3 includes a push rod 31 and a reset spring 32 arranged on the push rod 31. The push rod 31 includes a connecting portion and a sealing portion and a pushing portion respectively arranged at both ends thereof. The reset spring 32 is installed on the connecting portion. The push rod 31 is installed in the mounting groove, and its sealing portion is located in the through hole and seals the through hole. The reset spring 32 is located in the mounting groove. The pushing portion is located outside the mounting groove, and a boss is provided at one end where the pushing portion is connected to the connecting portion. The reset spring 32 is limited by the limiting surface between the boss and the inner wall of the mounting groove. The pushing portion can be pushed forward to move the sealing portion toward the inner wall of the lower shell 12 and push the float 4 to move, so that the float 4 leaves the drain port for drainage. After pushing, the reset spring 32 drives the push rod 31 to reset, and the sealing portion seals the through hole again.

[0041] Working principle:

[0042] The water inlet channel 111 of the drainer is connected to the end where the condensate needs to be discharged. The condensate enters the pre-filter 2 through the first channel 1111 and the second channel 1112. Since the second channel 1112 partially blocks the inlet 1221 of the water space 122, most of the condensate cannot flow directly into the water space 122. The condensate gradually accumulates in the pre-filter 2, and the impurities contained therein gradually settle at the bottom of the pre-filter 2. When the height of the condensate reaches the inlet 1221 of the water space 122, it gradually flows into the water space 122 after being filtered from the filter assembly. There is no condensate in the first space or the height of the condensate reaches the height of the float 4 (support column 123). The float 4 is in the first state due to its own gravity, and it blocks the drainage hole of the drainage channel 121. When the condensate in the water space 122 gradually increases and exceeds the height of the float 4, the float 4 floats up under the influence of buoyancy, so that it reaches the second state, opens the drainage channel 121 and then drains. When the condensed water is discharged to a height lower than the support column 123, the float 4 falls back onto the three support columns 123 under the influence of gravity, and then recloses the drainage channel 121. The three support columns 123 use inclined surfaces to enable the float 4 to fall more accurately into the drainage port of the drainage channel 121 to close the drainage port. After the drainer has been running for a period of time, the operator can check the precipitation of impurities through the perspective window 21 of the pre-filter 2 and remove the impurities in time. If the impurities reach half or more and gradually abut against the inlet 1221 of the water space 122, open the ball valve (not marked) to discharge the impurities in the pre-filter 2 from the impurity discharge port 22. The pre-filter 2 is tilted on the shell seat 1, which can better discharge the impurities. When the impurities cannot be discharged in full or in large part, the water inlet channel 111 can be connected to the water outlet device (faucet), flushed with water, and checked through the perspective window 21.

[0043] The above are only implementation methods of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present invention.
