DETAILED DESCRIPTION

[0017] 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. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-3 A multi-chamber liquid storage, heat preservation, filtering and backflow prevention drainer includes a main cup body, which includes a lower cup body 1 and an upper cup cover 2. The upper cup cover 2 is provided with card slots 3 on both sides, and a corresponding number of card seats 4 are provided on the lower cup body 1. The card slots 3 can be snapped with the card seats 4, and the snap-fit ​​structure can be easily disassembled for cleaning. Liquid inlet pipes 5 and liquid outlet pipes 6 are also provided on both sides of the lower cup body 1. The horizontal height of the liquid inlet pipe 5 is higher than the horizontal height of the liquid outlet pipe 6, so that the liquid can flow out smoothly.

[0019] Two small cup bodies 7 are installed in the main cup body, and a distance is left between the two small cup bodies 7. The purpose of leaving this distance is to form a chamber. A circular hole channel 8 is provided at the bottom of the small cup body 7, and a hollow float 9 is installed in the small cup body. The diameter of the hollow float 9 is larger than the diameter of the circular hole channel 8, so the hollow float 9 will close the circular hole channel 8 at the bottom of the small cup body 7 due to its own weight.

[0020] The inner wall of the upper cup cover 2 is close to the ports of the lower cup body 1 and the small cup body 7, and the upper ports of the lower cup body 1 and the small cup body 7 are sealed by the upper cup cover 2. The side of the small cup body 7 facing the liquid outlet pipe 6 is provided with an isolation fence filter 10. The side of the liquid outlet includes an isolation fence filter 10 to filter impurities in the liquid and prevent foreign matter from flowing back from the outlet. There is also a gap between the circular hole channel 8 at the bottom of the small cup body 7 and the bottom of the lower cup body 1. The gap setting allows liquid to enter, act on the hollow float 9 and push it open, so that the liquid Discharged from the isolation fence filter 10. In order to make the liquid flow to the isolation fence filter 10, the small cup body 7 and the lower cup body 1 are already closed by the upper cup cover 2, and the two sides and the bottom of the small cup body 7 need to be sealed. Therefore, a transverse interception structure is arranged between the outer wall of each small cup body 7 and the inner wall of the lower cup body 1, and the transverse interception structure corresponds to one side of the isolation fence filter 10, that is, the position of the transverse interception structure is arranged close to the liquid outlet pipe 6, so that the liquid first enters the circular hole channel 8 and then is discharged from the isolation fence filter 10.

[0021] The transverse interception structure includes a groove portion 11 and a protrusion portion 12. The groove portion 11 is arranged at the bottom and both sides of the outer wall of the small cup body 7, and the protrusion portion 12 is arranged at the bottom and both sides of the inner wall of the lower cup body 1. Since there is also a gap between the circular hole channel 8 and the bottom of the lower cup body 1, the height of the protrusion portion 12 at the bottom of the lower cup body 1 is greater than the groove depth of the groove portion 11 at the bottom of the small cup body 7. In order to better achieve the transverse interception effect of the liquid, the transverse width of the protrusion portion 12 is consistent with the transverse width of the groove portion 11, and the head end of the protrusion portion 12 contacts the bottom groove of the groove portion 11, so that there is no gap in the contact part between the groove portion 11 and the protrusion portion 12, and the structure only needs to open the upper cup cover 2, and the small cup body 7 can be pulled out upward, which is convenient for cleaning foreign matter in the small cup body 7.

[0022] The lateral interception structure and the hollow float 9 divide the main cup body into three chambers, a first chamber 100 connected to the liquid inlet pipe 5, a third chamber 300 connected to the liquid outlet pipe 6, and an independently sealed second chamber 200. The circular hole channel 8 is closed due to the deadweight of the hollow float 9. The first chamber 100 is a chamber outside one of the small cup bodies 7. Since the side of the small cup body 7 facing the liquid outlet pipe 6 is provided with an isolation fence filter 10, the third chamber 300 includes the chamber of the small cup body 7 in addition to the chamber outside the other small cup body 7. The second chamber 200 is a hollow float 9 that closes the circular hole channel 8 due to its deadweight. The two small cup bodies 7 are closed, and there is a spacing between them, so that an independent and sealed space that is not connected to the outside world is formed between the two small cup bodies 7. The independent and sealed space (i.e., the second chamber 200) and if there is gas reflux, the gas pressure will exert pressure on the upper part of the hollow float 9 to make the hollow float 9 and the circular hole channel 8 fit more closely to prevent gas reflux. The liquid in this space can minimize the evaporation of the liquid, so that the space can retain the liquid for a long time. The sealing of the liquid further prevents the reflux of gas and other debris, greatly improving the anti-reflux effect of the drainer, especially when there is no liquid inflow for a long time.

[0023] The outer wall of the upper cup cover 2 is provided with a groove, and a universal level 13 is installed in the groove. The upper cup cover 2 and the lower cup body 1 are provided with an external shield, and the external shield consists of an upper shield 14 and a lower shield 15. The upper shield 14 is provided with an observation hole 16, and the position of the observation hole 16 corresponds to the universal level 13. When installing, the user can observe the universal level 13 through the observation hole 16, and adjust the upper and lower left and right levels of the main cup body to prevent the horizontal height of the liquid outlet pipe 6 from being higher than the horizontal height of the liquid inlet pipe 5, so that the liquid can flow out smoothly. Semicircular structures are provided on both sides of the upper shield 14 and the lower shield 15. The two corresponding semicircular structures are assembled into a circular structure, and are wrapped around the liquid inlet pipe 5 and the liquid outlet pipe 6 and fixed with a clamp. The external shield is made of high-density pearl cotton material, which has a certain shockproof effect and can protect the cup body. The material also has a certain heat preservation function and can isolate the heat exchange between the liquid in the cup and the outside. If the liquid temperature is lower than the ambient temperature, the absence of an external shield will cause condensation on the surface of the cup, which may cause water seepage into the wall or affect the operation of mechanical equipment. At the same time, compared with polyurethane, which releases harmful substances such as isocyanate and poses certain safety hazards, pearl cotton is more environmentally friendly and safer. And if there are color requirements for the appearance, pearl cotton can be customized with color patterns to make the product look more beautiful.

[0024] Construction plan: Select the appropriate pipe diameter for the specific construction environment. Connect the drainer's inlet pipe 5 to the equipment's drain outlet, and connect the drainer's outlet pipe 6 to the external drain pipe, keeping the liquid flow direction consistent with the drainer's surface flow direction. After the connection is completed, adjust the position of the main cup body through the universal level 13, and fix the drainer after leveling.

[0025] Working principle: When the liquid continues to flow in, the liquid will enter the first chamber 100 from the liquid inlet pipe 5. As the liquid volume increases, when the liquid level is higher than the bottom of a small cup body 7 in front, the hollow float 9 inside the small cup body 7 will float up due to buoyancy, thereby connecting to the second chamber 200. As the liquid volume gradually increases, when the liquid level is higher than the isolation fence filter 10, the liquid will pass through the isolation fence filter 10 and enter the bottom of the second chamber 200. The liquid acts on the float of a small cup body 7 at the back, connecting to the third chamber 300, and finally the liquid will be discharged through the liquid outlet pipe 6.

[0026] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
