Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

It is to be noted that unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the present invention belongs.

As shown in fig. 1-11, a dry and wet universal deodorization floor drain comprises a floor drain shell 1 buried underground, and one side of the floor drain shell 1 is provided with a drainage connecting pipe 2 connected with an external drainage pipeline system. The top of the floor drain shell 1 is provided with a floor drain cover 3, and the floor drain cover 3 is provided with a drainage hole 4 which can collect accumulated water on the indoor ground into the floor drain shell 1. The floor drain shell 1 is also internally provided with a containing pool 5 and a dry-wet deodorization mechanism 6 positioned in the containing pool 5, and two ends of the containing pool 5 are respectively communicated with the drainage hole 4 and the drainage connecting pipe 2.

The dry and wet deodorization mechanism 6 comprises a deodorization core body 7 which is arranged in a hollow mode and a partition plate 10 which divides the interior of the deodorization core body 7 into a first channel 8 and a second channel 9, wherein the bottom of the first channel 8 is communicated with the containing pool 5, the bottom of the second channel 9 is provided with a fixing plate 11 which is isolated from the containing pool 5, and one side of the second channel 9 is communicated with the drainage connecting pipe 2. The top of the deodorization core body 7 is provided with a water blocking cover 12, a floating plate 13 with the density smaller than that of water is arranged between the water blocking cover 12 and the partition plate 10, and the periphery of the floating plate 13 is matched with the inner periphery of the deodorization core body 7.

When the ground leakage is in a dry area or in a wet area without water, the floating plates 13 are flatly pressed on the upper ends of the partition plates 10 by the self weight and are attached to each other. The outer periphery of the floating plate 13 is matched with the inner periphery of the deodorization core body 7, so that the floating plate 13 can completely cover the first channel 8 and the second channel 9 when being mutually attached to the upper end of the partition plate 10. Thus, when the odor of the sewer enters the deodorization core body 7 from the drainage connecting pipe 2, the odor is blocked from entering the first channel 8 under the action of the floating plate 13, so that the odor is prevented from entering the accommodating pool 5 through the first channel 8, and the odor is further prevented from returning to the ground so as to realize dry-region deodorization or waterless deodorization; and similarly, the ant and insect in the sewer can be prevented from passing through the floor drain and returning to the ground.

When the floor drain is in a running water state of a wet area, water flow on the ground flows into the floor drain shell 1 from the drainage holes 4 in the floor drain cover 3, at the moment, the drainage holes 4 perform primary filtration of hair, sundries and the like on the running water, the water flow passing through the drainage holes 4 is collected into the containing pool 5, and the water flow cannot flow into the interior of the deodorant core body 7 from the upper side of the deodorant core body 7 because the upper side of the deodorant core body 7 is covered by the water retaining cover 12. But only from the periphery of deodorizing core 7 (i.e., the gap between deodorizing core 7 and receiving tank 5) to the underside of receiving tank 5. Since the first passage 8 is communicated with the receiving tank 5, the water level depth entering the receiving tank 5 is the water level depth of the first passage 8, and the water flows through the receiving tank 5 into the interior of the first passage 8. At this time, the direction of the water flow is changed, and if the water flow once filtered through the drainage holes 4 still contains particle impurities such as silt, the water flow gradually sinks to the bottom of the accommodating pool 5, and the water flow flowing into the accommodating pool 5 is equivalent to be filtered again at this position.

If the water level in the accommodating pool 5 is gradually raised, the water flow entering the first channel 8 synchronously continues to flow upwards, and further jacks the floating plate 13 pressed on the partition plate 10 under the action of water pressure, and the floating plate 13 floats upwards under the action of the buoyancy of water until the floating plate pushes against the water retaining cover 12, so that the floating plate cannot float upwards continuously due to the fact that the density of the floating plate 13 is smaller than that of the water. At this time, the first passage 8 is communicated with the second passage 9, and the water flowing to the lower side of the floating plate 13 in the first passage 8 passes through the partition plate 10 and flows into the second passage 9, and is finally discharged from the drain connecting pipe 2.

After the water above the floor drain has completely flowed into the floor drain and drained, the water flow above the partition plate 10 will be drained. The water flow has to bypass the first passage 8 and pass over the partition 10 before it can be discharged. So when no further peripheral water flow continues, the water level in the receiving basin 5 and the water level in the first channel 8 will eventually remain at the same level as the partition 10 to just reach the equilibrium of the internal and external pressure differences, and the water will remain stationary and will not continue to flow. At this time, the water in the first channel 8 completely isolates the inner space and the outer space of the deodorization core body 7, and the effect of water sealing deodorization can be realized by preventing the inner air and the outer air from communicating with each other. In addition, the floating plate 13 falls down to recover to be attached to the partition plate 10 due to the self gravity, thereby recovering the water-free deodorization function. Therefore, at this time, the water seal deodorization function is superposed with the waterless deodorization function of the floating plate 13, so that the dual deodorization effect is achieved. If no external water flows into the upper part of the floor drain for a long time, the water stored in the first channel 8 in the deodorization core body 7 gradually and naturally evaporates, and the water sealing and deodorization functions are lost. However, the water-free deodorization function of the floating plate 13 and the partition plate 10 is still effective, namely, the double-sealing deodorization effect is reduced to the single-layer deodorization effect. However, under the normal use of most household wet areas, the water stored in the first channel 8 in the deodorization core body 7 always exists and is difficult to evaporate, so the floor drain disclosed by the application is in a double deodorization state in most of time.

Further, the top of the floor drain shell 1 is provided with a support table 14 which can be matched with the floor drain cover 3, the support table 14 is communicated with the accommodating pool 5, and the depth of the support table 14 is consistent with the height of the floor drain cover 3. When the floor drain cover 3 is mounted on the saddle 14, the upper surface of the floor drain cover 3 and the top of the floor drain shell 1 are in the same horizontal state.

Further, the side of the floor drain shell 1 is also provided with a skirt 15 which can be matched with ceramic tiles or floors or concrete. When the floor drain shell 1 is buried underground, the side skirt 15 can be embedded under the ceramic tile or under the floor or in concrete, so as to ensure that the floor drain shell 1 is fixed and is not easy to loosen.

Furthermore, one side of the deodorization core body 7 is provided with a guide pipe 16 which can be matched with the drainage connecting pipe 2 in an inserting way, the periphery of the guide pipe 16 is provided with a sealing groove 17, and a first sealing ring 18 which can be matched with the drainage connecting pipe 2 in a sealing way is arranged in the sealing groove 17. Through the effect of stand pipe 16, can realize deodorant core 7's location, avoid deodorant core 7 to shift under the rivers effect in the use. Meanwhile, the first sealing ring 18 can realize that water or gas can only be transferred from the drainage connecting pipe 2 to the guide pipe 16 or from the guide pipe 16 to the drainage connecting pipe 2, thereby avoiding leakage.

Furthermore, the bottom of the deodorization core body 7 is provided with a support leg 19, and the bottom of the support leg 19 is abutted with the bottom wall of the containing pool 5. By providing feet 19, the height of the position of the deodorizing core 7 is raised, so as to sufficiently give the water flow from the receiving tank 5 to the space in the first channel 8.

Furthermore, a limiting ring 20 is further disposed on the outer wall of the guide tube 16. When the guide pipe 16 is matched with the drainage connecting pipe 2 in an inserting way, one side of the limiting ring 20 is abutted against the inner wall of the deodorization core body 7, and then the limiting of the guide pipe 16 is realized. In this case, the feet 19 at the bottom of the deodorizing core 7 also stand on the bottom wall of the receiving tank 5.

Further, the number of the first channels 8 is preferably two in the present embodiment, and is respectively located at two sides of the second channel 9, specifically, the left channel 21 and the right channel 22. Therefore, the number of the partition plates 10 should be set to two independent from each other in this embodiment, and the area between the two partition plates 10 is the second passage 9. The flow speed of the water flow from the first channel 8 to the second channel 9 is increased by arranging the left channel 21 and the right channel 22 on two sides of the second channel 9 respectively. Meanwhile, when the water flow pushes the floating plate 13 upwards, the stress of the floating plate 13 can be more uniform, and the floating plate 13 is prevented from being inclined due to the stress of a single side, so that the upward or downward floating posture of the floating plate 13 is ensured.

Furthermore, the deodorization core body 7 is also internally provided with a sealing platform 23 capable of increasing the contact area with the floating plate 13, the top of the sealing platform 23 and the top of the partition plate 10 are positioned on the same plane, and one side of the sealing platform 23 is fixedly connected with the inner wall of the deodorization core body 7. Through addding seal platform 23 for floating plate 13 can hug closely the upper surface of baffle 10 and seal platform 23 under no rivers effect, thereby increases floating plate 13's area of contact, and it is more stable to ensure floating plate 13 to the effect of blockking of first passageway 8, second passageway 9.

Further, the water blocking cover 12 comprises an insertion block 24 which can be embedded into the deodorization core body 7, a positioning plate 25 which can be abutted against the top of the deodorization core body 7 is arranged at the top of the insertion block 24, and the cross sectional area of the positioning plate 25 is larger than that of the insertion block 24. The periphery of the plug block 24 is sleeved with a second sealing ring 26, the second sealing ring 26 is clamped between the water retaining cover 12 and the deodorizing core 7 and is sealed, so that water or gas cannot pass through a fit gap between the water retaining cover 12 and the deodorizing core 7, and the water retaining cover 12 cannot be pushed open by the normal water flow pressure.

Further, the accommodating pool 5 is provided with a filter screen cover 27 on the top of the deodorizing core 7, the filter screen cover 27 is provided with a plurality of strip-shaped filter tanks 28, the bottom of the filter screen cover 27 is provided with supporting legs 29, and the bottom of the supporting legs 29 stands on the bottom wall of the accommodating pool 5. The cross-sectional area of the screen cover 27 is adapted to the cross-sectional area of the receiving basin 5.

Because the screen panel 27 is located the below of floor drain cover 3, the top of deodorant core 7, after drainage hole 4 on floor drain cover 3 once filters, rivers need to pass through screen panel 27 to its below, because a plurality of rectangular shape filter tank 28 of screen panel 27 can make the water that flows through screen panel 27 obtain more careful second grade filtration once more. If particulate impurities such as silt still exist in the water after the secondary filtration, the impurities sink at the bottom of the accommodating pool 5, and the water flowing through the first channel 8 is equivalent to the tertiary filtration. Therefore, the floor drain of this application has tertiary filter effect.

Furthermore, a through hole 30 penetrating through the filter screen cover 27 is formed in one side of the filter screen cover 27, and a slider 31 convenient for a human hand to hold is arranged in the through hole 30. After using a period of time, need regularly clear up the floor drain described in this application to prevent the jam. When cleaning, the floor drain cover 3 is uncovered from the drainage hole 4 on the floor drain cover 3, and then the filter screen cover 27 can be conveniently lifted through the pull head 31 after the floor drain cover 3 is uncovered, so that the filter screen cover 27 can be cleaned.

Further, the slider 31 includes a lifting head 32, a connecting section 33, a limiting block 34, an elastic fitting block 35, and an inverted step 36, which are sequentially arranged from top to bottom. The lower surface of the limiting block 34 abuts against the upper surface of the filter screen cover 27, and the length of the connecting section 33 is the space for the hand of the human body to be inserted and held. The reverse step 36 is hooked on the lower surface of the strainer cover 27. The resilient engagement blocks 35 are preferably two in this embodiment and are arranged symmetrically to each other. A relief groove 37 is arranged between the two elastic matching blocks 35. Due to the existence of the abdicating groove 37 of the slider 31, the reverse step 36 on the slider can be retracted when entering the through hole 30 on the filter screen cover 27, and can be sprung outwards after passing through the through hole to realize reverse.

Further, a water outlet pipe 38 is further sleeved outside the water drainage connecting pipe 2, and the water outlet pipe 38 is connected with an external water drainage pipeline system. A third sealing ring 39 is arranged between the water outlet pipe 38 and the water drainage connecting pipe 2. The third sealing ring 39 seals the joint between the water outlet pipe 38 and the water discharge connecting pipe 2, so that gas or liquid can only enter the water discharge connecting pipe 2 from the water outlet pipe 38, or enter the water outlet pipe 38 from the water discharge connecting pipe 2, and leakage is avoided. More specifically, outlet pipe 38 may be part of an external drainage pipe system.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the scope of the embodiments of the present invention, and are intended to be covered by the claims and the specification.
