[0027] like Figure 1 to Figure 6As shown, the utility model discloses an automatic drainer, including a shell 1, a siphon structure, a sensing module 5 and a control module; the shell 1 has a relatively independent first space 13 and a second space 16, and a flow port is provided between the first space 13 and the second space 16 to connect them to each other, and at least one water inlet 111 and a drain port are provided on the shell 1, and the first water inlet 111 is located on the first space 13; the drainage component is arranged in the second space 16, and is used to open and close the drainage channel 2; the siphon structure, the siphon structure includes a siphon channel 4 and a solenoid valve arranged in the shell 1; the siphon channel 4 is lower than the drainage channel 2; the sensing module 5, the sensing module 5 is arranged in the shell 1, and is used to sense whether the water level or the pressure in the shell 1 reaches a preset value; the control module is used to receive the signal fed back by the sensing module 5, and open the solenoid valve for drainage.

[0028] Specifically, the shell 1 includes a first shell seat 11, a second shell seat 12 and a filter screen 15 with openings facing each other; the filter screen 15 is installed between the first shell seat 11 and the second shell seat 12, and the filter screen 15 divides the shell 1 into a first space 13 and a second space 16. The first shell seat 11 and the filter screen 15 form the first space 13, and the second shell seat 12 and the filter screen 15 form the second space 16. The bottom of the first space 13 has a sedimentation tank 14, and the side wall of the sedimentation tank 14 has a sewage discharge channel 112, and the sewage discharge channel 112 is provided with a sewage discharge valve; the middle part of the filter screen 15 has a filter hole 152, and its bottom is a blocking part 151, and there is no filter hole 152. Specifically, the blocking part 151 is a sealing plate to prevent impurities at the bottom of the first space 13 from entering the second space 16.

[0029] The water inlet is provided on the first housing 11. In this embodiment, there are two water inlet holes, one is provided on the top of the first housing 11, and the other is provided on the side wall of the first housing 11. The drainage channel 2 is provided on the second housing 1; the drainage assembly is provided on the side wall of the second housing 12, connected to the second space 16, and used to open and close the drainage channel 2. The siphon structure is provided on the side wall of the first housing 11 or the second housing 12, and its height at the housing is lower than the height of the drainage channel 2.

[0030] Specifically, the drainage assembly includes an L-shaped connecting rod 172 and a float 171; the L-shaped chain structure includes a sealing portion 1713, a hinged portion 1721 and a mounting portion 1712 in sequence; the hinged portion 1721 is used to be hinged in the second shell seat 12, and can be specifically hinged and fixed by a latch, etc. This hinged method belongs to the conventional technical means in this field and is not described here; the sealing portion 1713 is used to block the water inlet 111 of the drainage channel 2, and the mounting portion 1712 is used to install the float 171. The float 171 is lifted up by buoyancy, and rotates through the hinged portion 1721 to drive the sealing portion 1713 to open the drainage channel 2, thereby discharging the condensed water in the second space 16.

[0031] The siphon structure specifically includes a siphon channel 4 and a solenoid valve arranged in the shell 1. The siphon channel 4 is an inverted U-shaped channel. The heights of the two ends of the inverted U-shape are lower than the height in the middle. One end is connected to the first space 13 or the second space 16, and the other end is connected to the outside of the shell 1. The solenoid valve is located on the outside of the shell 1 and is connected to the siphon channel 4. The solenoid valve is used to receive a signal from the control module to control whether the siphon channel 4 is opened or not; the height of the siphon channel 4 in the shell 1 is lower than the height of the drainage channel 2 in the shell 1.

[0032] The sensing module 5 is a liquid level meter or a pressure sensor, which is arranged at the top of the first space 13 or the second space 16 and is used to monitor the water pressure in the drain as the height of the water level; when the water pressure or the water level in the drain reaches a preset value, the sensing module 5 transmits a signal to the control module, and the control module controls the solenoid valve to open for drainage.

[0033] It also includes a push rod mechanism 3. Specifically, the push rod mechanism 3 is used for manual drainage and pressure reduction. The push rod mechanism 3 includes a push rod 31 and a reset spring; the push rod 31 includes a pushing portion 131 and a resisting portion 132. The push portion 131 is located on the outside of the second shell seat 12. The resisting portion 132 is used to push open the blocking portion 1713 of the connecting rod 172; the reset spring is installed on the push rod 31. Specifically, the second shell seat 12 is provided with a through hole for the push rod 31 to pass through, and the outside of the through hole is provided with a mounting groove for installing the reset spring. The push rod 31 passes through the through hole from the outside and is located in the shell 1, and is used to resist the blocking portion 1713, push open the blocking portion 1713 and open the drainage mechanism 17.

[0034] Working principle:

[0035] The water inlet 111 is used to connect the end of the device. The condensed water at the end of the device enters the first space 13 through the water inlet 111. The condensed water in the first space 13 gradually increases and flows into the second space 16 through the filter 15. The filter 15 can filter out most of the impurities. As the condensed water in the second space 16 gradually increases, the float 171 is lifted up, and the float 171 drives the hinge 1721 of the connecting rod to rotate, thereby causing the blocking part 1713 to leave the drainage channel 2, so that the condensed water in the second space 16 is discharged from the drainage channel 2 to the drain.

[0036] When an abnormality occurs inside the drainer and the drain component cannot open the drain channel 2, as the condensed water in the second space 16 gradually increases, the pressure inside the drainer also gradually increases. When the water pressure of the condensed water in the drainer reaches a preset value or the water level reaches a preset value, the liquid level sensor or the pressure sensor transmits a signal to the control module. After receiving the signal, the control module controls the solenoid valve to open, discharges and reduces the pressure of the condensed water in the shell 1, and when the water level drops to a position lower than the siphon channel 4 or the pressure is less than the preset value, the control module controls the solenoid valve to close. The specific pressure varies according to the size of the drainer. The siphon channel 4 adopts an inverted U-shaped channel to form a siphon effect and can drain water more quickly.

[0037] When the drainage assembly and the siphon structure have malfunctioned and become ineffective, manual drainage can be performed through the push rod mechanism 3, which pushes the pushing portion 131 located on the outside of the drainer to drive the abutting portion 132 to abut against the blocking portion 1713 to push open the blocking portion 1713, so that the condensed water in the second space 16 can be discharged from the drainer.

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.
