In different types of shower rooms, the floor drains have different installation spaces, the height difference between the drain pipes and the ground is also different, the traditional floor drain needs more parts for installation and is complex to install, and the requirement for convenient installation of the floor drain device exists.

In view of this, the present application provides a floor drain device that is adjustable in height and level.

Referring to fig. 1 and 2, an embodiment of the present invention provides a floor drain device adjustable in height and level, comprising: water trap 20, seal assembly 30, connecting housing 40, and adjustment means.

The water trap 20 is used for receiving liquid flowing from the outside. As shown in fig. 3, in the illustrated embodiment, the water trap 20 includes a water trap body 21, a port flap 22, and a drain hole 23. The water trap body 21 is generally in the shape of an elongated rectangular groove, and port sealing pieces 22 are installed at two ends of the water trap body 21 and used for keeping the water trap 20 closed and preventing liquid from overflowing from two sides; the drain hole 23 is located at the bottom of the water trap body 21 and is in a strip shape to increase the water passing area. When the floor drain device works, liquid is gathered into the water trap 20 from the outside, flows into the drain hole 23 under the flow guidance of the water trap, and is drained downwards out of the water trap 20 from the drain hole 23.

Floor drain devices installed in different occasions need to have different lengths, and when the floor drain installation space is small or the ground slope is small, a water trap with a short length can be selected to avoid the shortage of the installation space; when the floor drain installation space is large or the ground slope is large, the water trap with the long length can be selected to avoid liquid overflow caused by insufficient capacity of the water trap.

In the present embodiment and various alternative embodiments, the length of the water trap body 21 is adjustable in order to facilitate installation in different situations. During installation, according to the size of an installation space, the size can be adjusted by cutting the integral longer water trap main body 21, and the multiple sections of shorter water trap main bodies can be spliced into the water trap main body 21 with the proper length.

For example, optionally, in some embodiments, the water trap body 21 is cut to adjust the length of the water trap 20. When the water trap is installed, under the condition that liquid can be guided into the drain hole 23 without obstruction, the water trap main body 21 is cut into corresponding lengths according to the size of an installation space, and then the port sealing piece 22 is installed to seal the water trap. The port seals 22 are detachably fitted tightly to both end portions of the water trap main body 21.

Optionally, in some embodiments, the surface of the port sealing sheet 22 is provided with a protrusion having the same length and width as the longitudinal section of the water trap main body 21. When the sealing device is installed, the side edges of the protruding parts are tightly matched with the left side surface and the right side surface inside the water trap main body 21 and slide downwards along the vertical direction until the bottom edges of the protruding parts are tightly matched with the ground inside the water trap main body 21, and the sealing of the water trap main body 21 is realized.

Referring to fig. 2 and 5, liquid exiting the water trap 20 via the drain hole 23 enters a connecting housing 40 attached to the water trap 20 at the location of the drain hole 23 in a fluid-tight manner.

The connection housing 40 is used to connect the water trap 20 to a drain pipe, as shown in fig. 2. In the present embodiment and the respective alternative embodiments, the connection housing 40 includes at least the water pipe connection portion 41, the water inlet hole 43, and the housing main body 44. The water inlet hole 43 is located at the uppermost end of the connection housing 40 opposite to the water discharge hole 23. The liquid discharged out of the water trap 20 through the water discharge hole 23 enters the housing main body 44 through the water inlet hole 43. The connection housing 40 is further connected to a drain line through a water pipe connection 41. The water pipe connection part 41 is attached to the housing body 44, directly connected to a sewer drain pipe. The water pipe connection portion 41 and the water discharge pipe may be directly connected by a reducer union, and the liquid is discharged from the water pipe connection portion 41 into the water discharge pipe after flowing through the housing body 44.

Alternatively, in some embodiments, when installing the floor drain device, the length of the water trap body 21 is first adjusted by cutting, the connecting shell 40 is attached to the water trap body 21, and finally the port sealing pieces 22 are added to both ends of the water trap body 21.

In order to block gas and insect damage in the drain pipes, in the present embodiment and in the various alternative embodiments, a water blocking assembly is further provided inside the connecting housing 40 between the housing body 44 and the water pipe connecting portion 41, as shown in fig. 6, the passage 46 is located at the lower portion of the housing body 44, the housing body 44 is connected to the water blocking assembly through the passage 46, and when liquid flows through the connecting housing through the passage 46, the water blocking assembly retains a certain amount of liquid inside, forming a liquid seal.

Alternatively, in some embodiments, as shown in fig. 6 and 2, an intermediate chamber 47 is provided between the housing main body 44 and the water pipe connection portion 41, a water stop plate 42 is provided inside the intermediate chamber 47, and during the process that the liquid flows from the channel 46 to the water pipe connection portion 41 inside the connection housing 40, the liquid is stopped by the water stop plate 42 to form an "S" shaped water path, so that the fixed liquid amount stays inside the water stop plate at the side of the water stop plate 42 close to the housing main body 44, and a tight water seal is formed. When the resident liquid level is above the water stop 42, excess liquid may pass over the water stop 42, be in fluid communication with the water connection 41 and be drained from the water connection 41.

Referring to fig. 4 and 5, the water trap 20 and the connection housing 40 are connected to each other in a fluid-tight manner via the seal assembly 30 to prevent leakage of liquid and drying of the liquid-sealed portions. As shown in fig. 5 and 6, the sealing assembly 30 includes a drain through hole 35. The sealing member 30 is sunk into the interior of the housing body 44 through the water inlet hole 43 while being closely fitted to the water trap body 21, and the drain through hole 35 is connected to the drain hole 23. This ensures that when the floor drain is in operation, all liquid exiting the drain hole 23 will flow through the drain through hole 35 into the housing body 44 without leaking out of the connection housing 40. The cross-sectional shapes of the seal assembly 30 and the housing body 44 in the horizontal direction substantially correspond to the shapes of the drain hole 23 and the water inlet hole 43, and are each, for example, an elongated strip shape having semicircular ends or other suitable shapes.

Alternatively, in some embodiments, as shown in fig. 5, the seal assembly 30 is a close fit with the water trap body 21 via an upper seal 32. An upper groove surrounding the drain hole 23 may be formed in a top end surface of the sealing assembly 30, an upper sealing member 32 is installed inside the upper groove, and the upper sealing member 32 may be, for example, a squeeze type sealing member, and elastically deforms in the upper groove to close a gap, thereby achieving fluid sealing between the sealing assembly 30 and the water trap main body 21. In other alternative embodiments, an upper groove may also be formed in the bottom surface of the water trap body 21 opposite the seal assembly 30 around the drain hole 23.

Optionally, as shown in the embodiment of fig. 5, the sealing assembly 30 may further be tightly fitted with the inner wall of the connection housing 40 by a lower sealing member 33. A lower groove may be provided around the outer circumferential surface of the seal assembly 30, and a lower seal 33 is installed inside the lower groove. The lower seal 33 may also be, for example, a squeeze-type seal that elastically deforms within the lower groove to close the gap and effect a fluid-tight seal between the seal assembly 30 and the inner wall of the coupling housing 40.

Optionally, in some embodiments, as shown in fig. 5 and 7, the water trap body 21 is further integrally formed with a T-shaped groove 215 extending throughout the length direction of the water trap at the bottom of the rectangular groove, and the top of the sealing assembly 30 is provided with an insertion portion 315 that can be matched with the T-shaped groove 215 in a shape. When mounting, referring to fig. 8, the insertion portion 315 may be inserted into the T-shaped groove 215 from one end opening of the water trap main body 21, and the seal assembly 30 is slid along the water trap main body 21 through the T-shaped groove 215 to adjust the position of the seal assembly 30 under the water trap main body 21 so that the drain through hole 35 and the drain hole 23 may be accurately connected.

According to the present invention, an adjusting means is provided between the sealing assembly 30 and the connection housing 40 for adjusting the height and level of the sealing assembly 30 and the water trap 20. In the installation of the floor drain device, the drain pipe is positioned below the ground, the height difference exists between the drain pipe and the ground, the connecting shell 40 is fixedly connected with the drain pipe, and the sealing assembly 30 and the water trap 20 are adjusted to form a whole through the adjusting assembly, so that the height of the floor drain device is consistent with the ground and is kept horizontal with the ground. More specifically, the seal assembly 30 is accommodated in the housing main body 44 via the water inlet hole 43 of the connection housing 40 at the lower side, and the insertion portion 315 of the seal assembly 30 is fixed in the T-shaped groove 215 of the water trap main body 21 around the water discharge hole 23 just below the water discharge hole 23, and the other end of the seal assembly 30 opposite to the insertion portion 315 is connected to the housing main body 40 in a vertically movable manner with respect to the housing main body 40 by an adjustment means, so as to adjust the vertical installation height of the water trap main body 21 and thus the water trap 20 with respect to the connection housing 40. The adjustment means may be any suitable means such as a threaded connection, a slide lock, etc.

As described above, the lower seal member 33 for achieving fluid-tightness between the seal assembly 30 and the inner wall of the housing main body 44 is mounted to the outer peripheral surface of the seal assembly 30, thereby allowing the seal assembly to maintain fluid-tightness with the inner wall of the housing main body 44 at all times during the above-mentioned adjustment.

Referring to fig. 8, the bottom surface of the water trap main body 21 is flush with the height of the water inlet hole 43 when the height is adjusted to be the lowest, and the sealing assembly 30 is always in sealing connection with the inner wall of the housing main body 44 during the height adjustment process in order to prevent leakage.

The filter assembly 50 shown in fig. 1 and the operation thereof according to the embodiment of the present invention will be described with reference to fig. 8 and 10. As shown in fig. 9, the filter assembly 50 is disposed in the housing body 44 and fixed inside the drain hole 23 and the drain through hole 35 for intercepting foreign materials in the liquid flowing from the water trap 20 to the connection housing 40 to filter the liquid. Since the filter assembly 50 is fixed between the drain hole 23 and the drain through hole 35, the height of the filter assembly 50 is synchronously adjusted with the water trap 20.

As shown in fig. 8, a handle 51 is installed at the top end of the filtering unit 50, and the handle 51 is detachably connected to a screen 52 located at the lower layer of the filtering unit 50, and the screen 52 is used to intercept sundries. The handle 51 is provided at its central portion with an arch 512 for easy gripping, and when the width of the water trap body 21 is sufficient to accommodate the hand of a user, the arch 512 can be gripped directly when cleaning the trash, and the filter assembly 50 can be lifted from the drain hole 23 by means of the handle 51. Alternatively, both ends of the handle 51 may be alternatively or additionally provided with protrusions 511, and when the width of the water trap body is insufficient to accommodate the user's hand, the user may directly pinch or pinch the protrusions 511 with his fingers to lift the filter assembly 50 upward.

Optionally, in some embodiments, a sinker mesh 53 is provided below the screen 52 to form an assembly that can intercept the deposited debris. In operation of the floor drain device, liquid in the water trap 20 passes through the filter assembly 50, wherein after a single filtration of the liquid through the screen 52, the remaining foreign objects flow with the liquid into the interior of the housing 40, wherein lighter foreign objects flow with the liquid, through the housing body 44 and out of the housing 40 through the passage 46, while heavier foreign objects sink within the housing body 44, are intercepted by the underlying sinker mesh 53 and finally settle on the sinker mesh 53. Preferably, the sinking net 53 is connected with the filter screen 52 through a sliding rod 55, the sliding rod 55 is fixed with the sinking net 53 and can vertically move up and down relative to the filter screen 52, and can be used for adjusting the distance between the sinking net 53 and the filter screen 52, when the sliding rod 55 slides to the top end, the sinking net 53 is closest to the filter screen 52, and when the sliding rod 55 slides to the bottom end, the sinking net 53 is farthest from the filter screen 52. In order to ensure that all light impurities can flow away with the liquid when the liquid flows through the housing body 44 when the floor drain device works, referring to fig. 6, the position of the sinking net 53 at the bottom of the filtering assembly 50 is set to be lower than the channel 46 at the horizontal height, specifically, the sliding rod 55 can naturally slide downwards through gravity, so that the sinking net falls at the lowest end of the housing body 44. During the height adjustment, the height of the water trap 20 and the seal assembly 30 relative to the connecting housing 40 changes, such that the height of the filter assembly 50 connected to the water trap 20 and the seal assembly 30 relative to the passage 46 inside the housing 40 changes. In this process, the sinking net 53 is always influenced by gravity and sinks to the lowermost end inside the housing main body 44. A plurality of through holes may be provided in the sinker net 53 to penetrate the sinker net 53 in a vertical direction so that, as the filter assembly 50 is lifted upward when cleaning the filter assembly 50, liquid can leak through the through holes without being intercepted, thereby reducing a liquid resistance to the sinker net 53 and debris deposited thereon and preventing the debris deposited during such lifting from falling back into the housing main body 44.

Referring to fig. 9 and 10, a trim strip assembly 60 for covering the notch of the water trap 20 is shown. The molding assembly 60 is composed of at least one spacer 61 and a plurality of fixing blocks 62. As shown in fig. 9, the partition 61 is disposed inside the water trap main body 21 to divide the water trap main body 21 into at least two parts, so that the area of the upward opening of the water trap main body 21 can be reduced, the appearance and safety can be achieved, and large objects can be prevented from falling into the water trap main body 21. In the embodiment shown in the drawings, the fixing block 62 is substantially in the shape of a letter "a little", and accordingly the partition plate 62 is formed in the shape of a lower opening frame so as to be smoothly put on the fixing block 62. The fixing blocks 62 are disposed in the water trap main body 21 at intervals, and connect the partition plate 61 with the water trap main body 21. The water flowing into the water trap body can smoothly flow out of the drainage hole 23 concentratedly through the gaps defined by the feet of the fixing block 62. When the water concentrator is installed, the length of the partition 61 can be adjusted in a cutting mode, or the partition 61 can be formed by splicing a plurality of sections of shorter partitions, so that the length of the partition 61 is consistent with that of the water concentrator main body 21, and the fixed block 62 and the partition 61 are prevented from moving in the length direction in the water concentrator main body 21; the width of the single fixing block 62 or the plurality of fixing blocks 62 placed side by side may be the same as the width of the water trap main body 21 to prevent the fixing block 62 and the partition plate 61 from moving in the width direction inside the water trap main body 21.

The adjustment device according to the embodiment of the invention shown in fig. 1 and its operating principle are described below with reference to fig. 4 and 5. As shown in fig. 5, the seal assembly 30 and the housing main body 44 of the coupling housing 40 are coupled to each other at both semicircular ends in the longitudinal direction thereof by adjusting bolts 701, 702. More specifically, through holes 301 and 302 are provided at both ends of the seal assembly 30 in the longitudinal direction, corresponding screw holes 401 and 402 are provided at positions opposite to each other inside the housing main body 44, stopper step portions 310 are provided inside the through holes 301 and 302, the adjusting bolts 701 and 702 are respectively located inside the through holes 301 and 302, and the bolt heads thereof are fitted to the top surfaces of the stopper step portions 310. The screw portions extend downwardly through the through holes 301, 302, respectively, and are threadedly engaged with the threaded holes 401, 402. In the process of adjusting the adjusting bolts 701 and 702 in the vertical direction, the bolt heads thereof may always abut against the top surface of the stopping step 310. When installed, the seal assembly 30 and the water trap 20, which are secured together, are connected to a connector housing 40 secured to the drain pipe. The sealing assembly 30 and the water trap 20 are integrated, the adjusting bolts 701 and 702 are positioned inside the water drainage holes 23, and the height of the adjusting bolts in the threaded holes 401 and 402 is controlled to be lifted and lowered by screwing the adjusting bolts 701 and 702 so as to adjust the height of the sealing assembly 30 and the water trap 20 relative to the connecting shell 40.

Two adjusting bolts 701 and 702 in the longitudinal direction of the sealing assembly 30 are spaced apart from each other by a certain distance, as shown in fig. 2, and by controlling the height of the adjusting bolts 701 and 702 respectively, the heights of the two ends of the sealing assembly 30 and the water trap 20 can be adjusted and controlled, and thus the levelness and the height of the sealing assembly 30 and the water trap 20 can be adjusted.

In some embodiments, as shown in fig. 4 and 5, card washers 711 and 712 may be disposed between the through holes 301 and 302 and the screw holes 401 and 402, and the adjustment bolts 701 and 702 are sequentially threaded through the through holes 301 and 302, the card washers 711 and 712, and the screw holes 401 and 402. As shown, the clamping washers 711, 712 may be U-shaped washers, and the adjusting bolts 701 and 702 may be formed with a reduced diameter portion between bolt head and shank portions thereof. In the process of lifting and lowering the adjusting bolts 701 and 702, the locking pads 711 and 712 are always in close fit with the diameter reducing portions of the adjusting bolts 701 and 702, and are pressed against the bottom surfaces of the stopping step portions 310 in the through holes 301 and 302. During the rotation and lifting of the adjusting bolts 701 and 702 in the threaded holes 401 and 402, the clamping pads 711 and 712 limit the vertical stroke of the adjusting bolts 701 and 702 in the through holes 301 and 302, so that the adjusting bolts and the sealing assembly 30 can keep the relative positions. That is, the adjusting bolts 701, 702 are changed together with the height of the seal assembly 30 when they are screwed.
