[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] The utility model provides: a central air-conditioning condensate water drainage device, such as Figure 1-Figure 4As shown, it includes a central air-conditioning main body 1, the top of the right side of the central air-conditioning main body 1 is connected to a water inlet pipe 2, the top of the right side of the central air-conditioning main body 1 is connected to a water outlet pipe 3, the right side of the water outlet pipe 3 is connected to a hose 4, the right end of the hose 4 is connected to a circular sleeve 5, the inside of the circular sleeve 5 is fixedly connected to a connecting plate 6, the right side of the connecting plate 6 is fixedly connected to a connecting rod 7, the surface of the connecting rod 7 is slidably connected to a disc 8, the arc surface of the disc 8 is in contact with the inner wall of the circular sleeve 5, the inside of the circular sleeve 5 is fixedly connected to a ring 9, the left end of the disc 8 is in contact with the right end of the ring 9, the surface of the connecting rod 7 is sleeved with a tension spring 10, the left end of the tension spring 10 is fixedly connected to the right side of the connecting plate 6, and the right end of the tension spring 10 is fixedly connected to the left end of the disc 8.

[0023] In this embodiment, by setting the disc 8, ring 9 and tension spring 10, when the condensed water inside the central air-conditioning body 1 needs to be discharged, the condensed water will be transported to the outlet pipe 3, hose 4 and the inside of the circular sleeve 5 in sequence. Since the disc 8 will be subjected to the impact force of the condensed water, when the disc 8 moves to the left, it will not only pull the tension spring 10, but also separate from the circular ring 9, so that the condensed water can be discharged. When the condensed water inside the circular sleeve 5 is drained, since the disc 8 is always subjected to the tension of the tension spring 10, the disc 8 will automatically reset, so that the left end of the disc 8 will contact the right end of the ring 9, thereby preventing mosquitoes and the like from the outside from entering the interior of the circular sleeve 5, which will cause the circular sleeve 5 to be blocked and the condensed water cannot be discharged.

[0024] Preferably, a slide groove 11 is provided at the top and bottom of the arc surface of the connecting rod 7, and a through groove 12 is provided at the top and bottom of the right side of the disc 8. The interior of the through groove 12 is rotatably connected to a roller 13 through an axle pin, and the bottom of the roller 13 extends to the interior of the slide groove 11. The roller 13 and the through groove 12 are rollingly connected, and the right end of the connecting rod 7 is fixedly connected to a round block 17, and the right end of the round block 17 is in contact with the left side of the filter screen 14.

[0025] By setting the roller 13, the through groove 12 and the round block 17, the friction between the disc 8 and the connecting rod 7 can be reduced when it moves, preventing the condensed water inside the circular sleeve 5 from hitting the disc 8 and getting stuck on the surface of the connecting rod 7, thereby preventing the condensed water from being discharged.

[0026] Among them, a filter screen 14 is provided on the right side of the circular sleeve 5, the left side of the filter screen 14 is in contact with the right side of the circular sleeve 5, the top and bottom of the right side of the filter screen 14 are detachably connected to the circular sleeve 5 by bolts, and four groups of positioning grooves 15 are opened on the right side of the circular sleeve 5. Four groups of positioning pins 16 are fixedly connected to the left side of the filter screen 14, and the left end of the positioning pin 16 extends to the inside of the positioning groove 15, and the positioning pin 16 and the positioning groove 15 are plugged into each other.

[0027] In this embodiment, the filter 14 is provided to prevent larger foreign matter from entering the circular sleeve 5. When larger foreign matter enters the circular sleeve 5, not only will the circular sleeve 5 be clogged, but some foreign matter will also attract mosquitoes, thereby causing serious blockage inside the circular sleeve 5 and making it impossible to discharge the condensed water normally.

[0028] It is worth noting that an annular groove 18 is provided at the right end of the ring 9, and an annular sealing ring 19 is fixedly connected to the left end of the disc 8. The left side of the annular sealing ring 19 contacts the left side of the inner wall of the annular groove 18. The top and bottom of the inner wall of the circular sleeve 5 are fixedly connected with an L-shaped buffer block 20. The right side of the L-shaped buffer block 20 contacts the left end of the disc 8. The right side of the L-shaped buffer block 20 is made of soft rubber.

[0029] Through the arrangement of the annular sealing ring 19 and the L-shaped buffer block 20, the annular sealing ring 19 can increase the sealing performance when the disc 8 and the ring 9 are in contact, preventing dust from entering the interior of the hose 4 through the gap, while the L-shaped buffer block 20 can prevent the tension of the tension spring 10 from being too large, and the impact force generated when the disc 8 is reset is too large to cause damage to the ring 9. The L-shaped buffer block 20 can effectively reduce the impact force of the disc 8.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
