Description

Technical Field

[0001] The invention relates to the technical field of bathtub appliances, in particular to a device for precipitating and filtering impurities in water after bathing and a bathtub. Background Art

[0002] As people's living standards continue to improve, people are paying more and more attention to water pollution. The bath water produced by people when bathing is also a factor causing daily water pollution.

[0003] In order to solve the problem of daily water pollution, people have specially designed some water treatment devices used in bathroom products to solve the problem of daily water pollution, such as the filter cartridge device disclosed in the Chinese utility model patent document with publication number CN219110973U. These filter cartridges equipped in the bathtub can filter impurities in the water after bathing generated by people when bathing in the bathtub, so that the impurities are not discharged into the external environment with the water to cause pollution; but since there are impurities such as human hair, soil, detergent, human oil and fat in the water after bathing, using a simple filter net for filtering can only remove large-volume impurities in the water, and for small-volume impurities in the water, it is necessary to use a filter membrane with a very small pore size such as a reverse osmosis membrane for filtering. If the filter membrane is arranged perpendicular to the water flow direction, when filtering the water after bathing, the filtered impurities are easily attached to the surface of the filter membrane for a long time under the driving effect of the water flow, resulting in a reduction in the filtering effect of the filter membrane, and the filter membrane will be subjected to a certain water pressure shock when in use, and the setting method of the filter membrane will also affect its stability in use.

DETAILED DESCRIPTION

[0025] The present invention discloses a device for precipitating and filtering impurities in water after bathing, such as Figure 1 and Figure 2 As shown in combination, the device includes an adapter 1, a cavity is provided inside the adapter 1, the adapter 1 has at least two ports connected to the cavity, a sieve plate 2 with a plurality of filter holes is provided in the cavity near the water outlet end of the adapter 1, the water outlet end of the adapter 1 is connected to a segmented pipe body 3, the bottom end of the segmented pipe body 3 is matched with a segmented pipe body 2 4 by a detachable connection, the segmented pipe body 1 3 is combined with the segmented pipe body 2 4 to form a drainage pipe 5 with a closed ring radial cross section, a recessed portion 6 with a downward recessed direction is provided at the bottom of the segmented pipe body 2 4, a positioning component 7 located at the front and rear ends of the recessed portion 6 is provided in the drainage pipe 5, a filter membrane 8 is provided in the drainage pipe 5 for positioning by the positioning component 7 and by the segmented pipe body 1 3 and the segmented pipe body 2 4, the filter membrane 8 is inclined to separate the internal space of the drainage pipe 5 above the recessed portion 6, and separates at least two sedimentation chambers 9.

[0026] It should be noted that after bathing, the water enters the cavity mouth of the adapter 1 from the port of the adapter 1, and will flow to the port of the adapter 1 near the side of the sieve plate 2. When the water flows through the sieve plate 2, the sieve plate 2 will block and filter some large impurities in the water, such as hair, dead skin, etc., while the water mixed with small impurities will flow into the drainage pipe 5 from the water outlet end of the adapter 1 through the filter holes on the sieve plate 2; after entering the drainage pipe 5, the water will flow to the filter membrane 8, and the filter membrane 8 will filter the insoluble impurities in the water after bathing, so that the turbidity in the water after bathing can be precipitated and blocked in the sedimentation chamber 9 in the drainage pipe 5 for storage or accumulated on the surface of the filter membrane 8, so that the insoluble impurities in the water will remain in the drainage pipe 5 and will not be discharged with the water, so that the water discharged outside the bathtub can be immediately recovered for reuse; the filter membrane 8 is arranged in an inclined manner. The internal space of the drainage pipe 5 is divided. When water flows through one side of the filter membrane 8, the area of ​​the filter membrane 8 for filtering impurities can be increased compared to the setting of the filter membrane 8 in a cross-section parallel to the radial direction of the drainage pipe 5, which can not only filter the insoluble impurities in the water faster, but also enhance the anti-impact performance of the filter membrane 8; in addition, the screen can slow down the water flow rate. After the flow rate of the water entering the drainage pipe is slowed down, the pressure on the protective membrane of the filter membrane 8 will become smaller, thereby preventing the filter membrane 8 from being torn due to excessive water flow pressure; in addition, since the segmented pipe body 2 4 is connected to the segmented pipe body 1 3 in a detachable manner, when it is necessary to remove impurities in the drainage pipe or replace the filter membrane 8, the segmented pipe body 2 4 can be removed from the device alone without dismantling the entire drainage pipe 5, which is convenient for the user's handling operation.

[0027] As a further preference of the above embodiment, Figures 2~5 As shown in the combination, one of the axial ends of the segmented tube body 3 is a mating end 10, the mating end 10 is annular and has an inner thread on the inner wall, the outer wall of the adapter 1 near its water outlet end is provided with an outer thread, the segmented tube body 3 is connected to the water outlet end of the adapter 1 by means of the mating of internal and external threads, both sides of the segmented tube body 3 are provided with mating parts 11 with a hook-shaped cross-section, the mating parts 11 extend along the axial direction of the segmented tube body 3 and form a first mating groove 12 in the middle, both sides of the segmented tube body 2 4 are provided with mating blocks 13 extending along the axial direction of the segmented tube body 2 4, the segmented tube body 2 4 is detachably connected to the bottom of the segmented tube body 3 through the mating between the mating block 13 and the first mating groove 12, and the positioning assembly 7 and the filter membrane 8 are both arranged in the segmented tube body 2 4.

[0028] Among them, the segmented pipe body 1 3 is connected to the water outlet end of the adapter 1 in a threaded manner, and because the segmented pipe body 2 4 is connected to the segmented pipe body 1 3 by using the matching block 13 to fit into the matching groove, the segmented pipe body 2 4 can not only be removed separately from the drainage pipe 5, but the entire drainage pipe 5 can also be removed from the water outlet end of the adapter 1. When cleaning impurities in the drainage pipe 5, replacing the filter membrane 8 or replacing the positioning component 7, the segmented pipe body 2 4 or the entire drainage pipe 5 can be removed according to specific operation needs.

[0029] As a further preference of the above embodiment, Figure 4 As shown, the positioning assembly 7 includes a first sealing ring 14, a first positioning ring 15, a second positioning ring 16 and a second sealing ring 17. The inner wall of the end of the segmented tube body 2 4 close to the adapter 1 is provided with an annular first baffle 18. The first sealing ring 14 and the first positioning ring 15 are sequentially arranged in the end of the segmented tube body 2 4 outside the first baffle 18 in a direction away from the center of the segmented tube body 2 4. The inner wall of the middle part of the segmented tube body 2 4 is provided with two semicircular second baffles 19 extending upward in an interval manner. The second positioning ring 16 and the second sealing ring 17 are provided with a first baffle 18. The filter membrane 8 is sequentially arranged in the end of the segmented tube body 2 4 between the two second baffles 19 along the direction close to the first baffle 18, one end of the filter membrane 8 is clamped between the first sealing ring 14 and the first positioning ring 15 above the segmented tube body 2 4, and extends along the axial direction of the segmented tube body 2 4 to cover the inner wall of the segmented tube body 2 4 until it reaches the middle of the segmented tube body 2 4. After the middle part of the filter membrane 8 is pressed against the inner wall of the segmented tube body 2 4 by the bottom of the second positioning ring 16 and the bottom of the second sealing ring 17, it passes through between the second positioning ring 16 and the second baffle 19 from bottom to top.

[0030] Among them, when the filter membrane 8 is set in the segmented tube body 2 4, the first sealing ring 14 is first placed on one side of the first baffle 18, and then one end of the filter membrane 8 is placed on the part where the first sealing ring 14 extends above the segmented tube body 2 4, and completely covers the end surface of the first sealing ring 14 above the segmented tube body 2 4, and then the first positioning ring 15 is installed in the end of the segmented tube body 2 4 outside the first baffle 18, so as to clamp and fix one end of the filter membrane 8; after fixing one end of the filter membrane 8, the filter membrane 8 turns over the first baffle 18, and covers the surface of the segmented tube body 2 4 outside the first baffle 18 in a top-to-bottom manner until it reaches the middle of the segmented tube body 2 4; after the middle part of the filter membrane 8 covers the surface of the segmented tube body 2 4 below the second baffle 19, the filter membrane 8 is then removed from Pull it up from the bottom to the second baffle 19 farthest from the adapter 1, and then place the second positioning ring 16 and the second sealing ring 17 between the two second baffles 19. The bottom of the second positioning ring 16 and the bottom of the second sealing ring 17 are pressed on the surface of the middle part of the filter membrane 8, so that the filter membrane 8 is set in an inclined form, and sedimentation chambers 9 are formed in the internal space of the drainage pipe 5 on the upper and lower sides of the filter membrane 8. Since the temperature will affect the solubility of substances such as oil, solvents, etc. in the water after bathing, precipitation of substances may occur on the upper and lower sides of the filter membrane 8, thereby forming precipitation. The sedimentation chambers 9 on the upper and lower sides of the filter membrane 8 are both closed chambers. The impurities in the water after bathing will be accumulated in the sedimentation chamber 9 after precipitation and will not be discharged to the outside of the drainage pipe 5 with the water flow.

[0031] As a further preference of the above embodiment, Figure 4 As shown, the positioning assembly 7 also includes a third positioning ring 20 and a third sealing ring 21. The inner wall of the end of the segmented tube body 24 away from the adapter 1 is provided with a third baffle 22 in a semicircular shape and extending upward. The third positioning ring 20 and the third sealing ring 21 are sequentially arranged in the end of the segmented tube body 24 outside the third baffle 22 in a direction away from the center of the segmented tube body 24. After the middle part of the filter membrane 8 passes between the second positioning ring 16 and the second baffle 19, it extends along the axial direction of the segmented tube body 24 to cover the inner wall of the segmented tube body 24 until it reaches the end of the segmented tube body 24 close to the third baffle 22. One end of the filter membrane 8 is clamped between the bottom of the third positioning ring 20 and the third sealing ring 21.

[0032] Among them, when the filter membrane 8 is pulled from bottom to top to the second baffle 19 farthest from the adapter 1, the filter membrane 8 turns over the second baffle 19 and covers the surface of the segmented tube body 24 outside the second baffle 19 in a top-to-bottom manner until it reaches the end position of the segmented tube body 24 below the third baffle 22, and then the third positioning ring 20 is installed into the end of the segmented tube body 24 near the third baffle 22 side, and the filter membrane 8 is pulled up to cover the bottom end surface of the third positioning ring 20. After the third positioning ring 20 is fully installed, the bottom end of the third positioning ring 20 will press the filter membrane 8, and then the third sealing ring 21 is installed into the end of the segmented tube body 24 near the third baffle 22 side, and the other end of the filter membrane 8 is clamped by the third positioning ring 20 and the third sealing ring 21, so that the other end of the drainage pipe 5 and the position near the recessed portion 6 side form a sedimentation chamber 9, which further blocks and filters the residual impurities or precipitated substances in the water after bathing.

[0033] As a further preference of the above embodiment, Figure 3 , Figure 4 and Figure 6 As shown in the combination, the end of the segmented tube body 1 3 away from the adapter 1 and the end of the segmented tube body 2 4 away from the adapter 1 are both provided with an extension section 23, and the outer side of the extension section 23 is matched with a hollow end cover 24 by means of internal and external threads, and the end cover 24 is provided with an elastic gasket 25 abutting against the end face of the third sealing ring 21.

[0034] Among them, the end cover 24 is engaged with the extension part in a threaded manner, so that the segmented pipe body 1 3 and the segmented pipe body 2 4 are tightly connected together. When the drainage pipe 5 is removed, the segmented pipe body 1 3 and the segmented pipe body 2 4 can be removed at the same time, and there is no need to worry about the segmented pipe body 2 4 being loosened from the segmented pipe body 1 3 when the drainage pipe 5 is removed; and the elastic gasket 25 can be pressed on one side of the third sealing ring 21 when the end cover 24 is installed, so as to fix the position of the third sealing ring 21 and make the other end of the filter membrane 8 more stably fixed.

[0035] As a further preference of the above embodiment, Figure 4As shown, both sides of the top of the segmented tube body 24 are provided with first sealing grooves 26 extending radially along the segmented tube body 24, and a sealing strip 27 is provided in the first sealing groove 26.

The extended section 23 at the end of the segmented tube body 24 is provided with a second matching groove 29 connected to the first sealing groove 26. The first protrusion 28 is fitted in the second matching groove 29 and abuts against one end of the sealing strip 27. Both sides of the first positioning ring 15 are provided with second protrusions 30. The second protrusion 30 is fitted in the end of the first sealing groove 26 away from the elastic gasket 25 and abuts against the other end of the sealing strip 27.

[0036] Among them, both sides of the filter membrane 8 extend into the first sealing groove 26, and after the sealing strip 27 is installed in the first sealing groove 26, it presses the two sides of the filter membrane 8, thereby fixing the position of the filter membrane 8 and sealing the two sides of the filter membrane 8; the first protrusion 28 is matched in the second matching groove 29 to limit one end of the sealing strip 27, and when the first positioning ring 15 is installed, the second protrusion 30 can be matched in the end of the first sealing groove 26 to limit the other end of the sealing strip 27. After the segmented tube body 2 4 is installed under the segmented tube body 1 3, the sealing strip 27 is surrounded by the first protrusion 28, the second protrusion 30, the matching part 11 and the first sealing groove 26, thereby fixing the position of the sealing strip 27 and avoiding water leakage at the edge of the drainage pipe 5.

[0040] Among them, before the drainage pipe 5 is installed, the sieve plate 2 needs to be installed into the water outlet end of the adapter 1 along the direction of the third protrusion 33 and the third matching groove 34, and then the drainage pipe 5 is installed to the water outlet end of the adapter 1. After the drainage pipe 5 is installed, the port of the third matching groove 34 is closed by the positioning component 7 in the drainage pipe 5 close to the side of the adapter 1, so as to fix the position of the sieve plate 2 to avoid the position of the sieve plate 2 from being offset.
