Description

Drainer

Technical Field

The application relates to the technical field of kitchens and bathrooms, in particular to a drainer.

Background

The kitchen basin is also called a kitchen sink, a user washes dishes and bowls in the kitchen basin, and leaves and leftovers are collected in a filter basket at the bottom of the kitchen basin. The drainage port at the bottom of the traditional vegetable basin is internally provided with the filtering basket and the water sealing cover is arranged on the filtering basket, and the water is drained and the solid garbage is collected in the filtering basket by taking down the water sealing cover. CN217998296U (publication No. 2022.12.09) discloses a magnetic seal drainer in which the state of the bouncing core is switched by pressing the pressing lever, so that the water seal plate is switched between the open position and the closed position. As the water flow passes downwardly through the water seal plate and into the upper portion of the deodorant closure plate, the deodorant closure plate moves downwardly so that the water flow is discharged downwardly as the accumulated water flow is sufficient to resist the repulsive force between the first and second magnets. After the water flow discharge is finished, the deodorizing sealing plate upwards seals the lower opening of the outer cylinder under the action of magnetic repulsive force, namely, the deodorizing sealing plate returns to the deodorizing state, so that the odor in the sewer pipe is prevented from flowing back upwards;

the filter basket above the water sealing plate is used for collecting garbage; because the depth of the water outlet of the water tank is limited and the depths of different water tanks are different, the overall height of the water outlet of the water tank (namely the dimension H1 in the figure 2) needs to be controlled so as to ensure that the water outlet of the water tank can be matched with more water tanks as much as possible, and the overall height needs to be compact so as to be suitable for installing more water tanks; meanwhile, the larger the depth H2 of the filter basket is, the larger the containing cavity of the filter basket is, the more the product of the drainer has market competitiveness; this creates a conflict between the overall height of the drainer and the basket receiving chamber.

Moreover, as the characteristic of the bouncing core 3 can be known, as shown in fig. 6, the stop hook moves in a unidirectional circulation way in the hook groove structure; when the bouncing core 3 is switched from the contracted state to the extended state, the bouncing core needs to be further contracted by a distance D2 from the contracted state, namely, when the water sealing plate 4 is switched from the water sealing state to the water draining state, the bouncing core needs to be further compressed downwards by the distance D2 from the water sealing state; the bouncing core 3 is switched from the extended state to the contracted state, and also needs to be compressed more distance D2 than in the contracted state; a transverse rib is provided between the water seal plate and the deodorant sealing plate in CN217998296U, so in CN217998296U, the distance H5 between the lower side of the water seal plate 4 and the deodorant sealing plate 2 is at least the thickness of the rib + the distance D2. Under the condition that the overall height H1 of the drainer meets the requirement, the depth of the filter basket 5 is made shallower; or meets the requirement of the depth of the filter basket 5, but the whole height of the drainer needs to be increased, so that the drainer is only suitable for a deeper water tank drain.

Chinese patent CN216787326U proposes that the outer shell is fixed in the drain openings with various sizes by arranging a reducing silica gel ring on the outer side of the outer shell, so that the reducing silica gel ring is suitable for the drain openings with various sizes; the reducing silica gel ring comprises an inner ring and a plurality of outer rings with different outer diameters, the outer rings with different outer diameters are transversely arranged on the outer wall of the inner ring, the outer diameter of the outer ring in the middle is largest, and the outer diameter of the outer ring at the edge is smallest. Although the use of multiple outer rings with different outer diameters as shown in CN216787326 can solve the problem of different inner diameters of the drain opening of different tanks, this greatly increases the cost of the outer seal ring.

In the technical scheme disclosed in chinese patent CN217998296U, the first magnet and the second magnet are larger magnetic rings, and the magnetic ring sleeve and the bouncing core are coaxially sleeved. The larger magnetic ring is high in material cost, and the magnetic ring is troublesome to install and fix, so that the assembly cost is high.

In view of the above, the present inventors have made intensive studies to solve the above-mentioned drawbacks of the prior art.

Detailed Description

In order to further explain the technical scheme of the application, the application is explained in detail by specific examples.

As shown in fig. 1 to 11, the application relates to a drainer, which is provided with a drainer housing 1 and a deodorizing closing plate 2; the deodorization sealing plate 2 is arranged on a center seat 6 at the lower outlet of the drainer shell 1 in a sliding manner, the lower end of the center seat 6 is connected with the drainer shell 1 through a transverse rib 61, and the deodorization sealing plate 2 is positioned above the transverse rib 61.

In this way, the drainer according to the present application, by arranging the transverse rib 61 below the deodorizing cover plate 2, makes the deodorizing cover plate 2 slide above the transverse rib 61, and is more compact in structure, and ensures that the sliding space of the deodorizing cover plate 2 does not interfere with the inner wall of the drain port 100. The deodorizing closing plate 2 is not easy to be blocked by the inner wall of the water outlet 100 to influence the water discharge.

Preferably, the plurality of transverse ribs 61 are equally spaced around the axial direction of the drainer housing 1.

Preferably, the water-sealing device also comprises a bouncing core 3, a water sealing plate 4 and a filtering basket 5; the fixed end of the bouncing core 3 is connected with the center seat 6, the water sealing plate 4 is connected with the movable end of the bouncing core 3, and the water sealing plate 4 is provided with a water sealing state which is switched to a water draining state. Preferably, the bouncing core 3 comprises an outer cylinder 31 and an inner core 32 sliding in the outer cylinder 31, the inner core 32 is in threaded connection with the central seat 6, a connecting cylinder 41 is formed on the upper portion of the water sealing plate 4, and the inner wall of the connecting cylinder 41 is in threaded connection with the outer cylinder 31. As shown in fig. 2, the inner core 32 is in threaded connection with the central seat 6, the outer cylinder 31 is upward and connected with the water sealing plate 4, and the overall structure is compact, so that the overall height of the drainer product is reduced.

Furthermore, in the state switching process of the water sealing plate 4, the lowest position of the downward movement of the lower end of the water sealing plate 4 is lower than the position of the upper surface of the deodorizing sealing plate 2 in the deodorizing state.

As shown in fig. 2, the height H1 of the entire drainer is composed of the following parts:

1. the height H2 of the filter basket is as large as possible in order to ensure the size of the cavity of the filter basket;

2. the movement path H3 of the water seal 44, which switches from the water seal state to the water drain state, depends on the distance D1 between the two stable positions in the bouncing core 33, and is a constant value after the bouncing rod is selected.

3. The thickness H4 of the water seal plate 44; the water sealing plate 44 is provided with a water sealing ring, and the water sealing plate 44 needs to have a certain thickness for installing the water sealing ring; under the condition of meeting the use requirement, H4 is already made as small as possible.

4. A distance H5 between the underside of the water seal 44 and the deodorant closure 22.

5. The edge thickness H6 of the deodorizing closing plate 22; under the condition of meeting the use strength, H6 is already made as small as possible.

6. The distance H7 between the lower end of the deodorizing closing plate 22 and the bottom of the sewage, and the space of the part is required to ensure that the side part of the deodorizing closing plate 22 after downward movement has enough drainage space, thereby ensuring the smoothness of drainage.

From the above analysis, it can be seen that: h1 =h2+h3+h4+h5+h6+h7; wherein H3, H4, H6 and H7 are all made as small as possible under the condition of meeting the use requirement, and the recompression space is not large; therefore, in order to solve the contradiction between the small requirement of H1 and the large requirement of H2, H5 needs to be made small.

By arranging the bouncing core 3, the water sealing plate 4 can be switched between a water sealing state and a water draining state by pressing; because the lowest position of the lower end of the water sealing plate 4, which moves downwards, is lower than the position of the upper surface of the deodorization sealing plate 2 in the deodorization state in the state switching process, when the water sealing plate 4 in the water sealing state is pressed downwards to be ready for switching to the drainage state, the downward movement of the water sealing plate 4 can push the deodorization sealing plate 2 downwards for a distance, so that the height of the interference between the water sealing plate 4 and the deodorization sealing plate 2 is the common height of the water sealing plate 4 and the deodorization sealing plate 2, and the distance between the lower part of the water sealing plate 4 and the deodorization sealing plate 2 can be smaller than the recompression distance in the compression direction when the bouncing core 3 is switched; the distance H5 between the lower part of the water sealing plate 4 and the deodorizing closing plate 2 in fig. 2 can be designed smaller, so that the contradiction between the whole height of the drainer and the volume of the guaranteed filter basket 5 is relieved; in the case of a defined overall height of the drainer, the filter basket 5 can have a greater depth. In the case of a depth determination of the filter basket 5, the overall height of the drainer is smaller. Because the transverse ribs 61 are arranged below the deodorizing sealing plate 2, no blocking of the transverse ribs 61 exists between the deodorizing sealing plate 2 and the water sealing plate 4, and the condition that the water sealing plate 4 can move downwards to the lowest point to interfere with the position of the upper surface of the deodorizing sealing plate 2 in the deodorizing state is created.

Preferably, a through hole is formed in the middle of the filter basket 5, a driving cylinder 51 is further disposed in the through hole, and the driving cylinder 51 is sleeved on the connecting cylinder 41 from top to bottom. In use, the state of the water sealing plate 4 is switched by pressing the connecting cylinder 41.

Preferably, the lower surface of the filter basket 5 is in a plane shape which is horizontally arranged, and the upper surface of the water sealing plate 4 in a drainage state is attached to the lower surface of the filter basket 5. The space between the filter basket 5 and the highest position of the water sealing plate 4 is thus fully utilized, so that the filter basket 5 has a large volume. Preferably, the lower surface of the water sealing plate 4 is upwards provided with a downward opening abdication cavity 42; the thickness of the inner part of the deodorizing closing plate 2 is larger than that of the edge; when the lower end of the water sealing plate 4 moves downwards to the lowest position, part of the upper surface of the deodorizing sealing plate 2 enters the abdication cavity 42. So reduced the thickness H6 at deodorant shrouding 2 edge, the space of the direction of height of saving, deodorant shrouding 2 middle part thicker part can hold in the cavity 42 of stepping down.

Preferably, the outer sealing ring 13 is further included, the drainer housing 1 has an outer side wall 11, and an annular inclined wall 111 with a large upper part and a small lower part is formed on the outer side wall 11; the distance between the upper edge and the lower edge of the annular inclined wall 111 is larger than the upper width and the lower width of the inner ring 131 of the outer sealing ring 13; the inner ring 131 of the outer seal ring 13 is sleeved on the annular inclined wall 111 and is attached to the annular inclined wall 111 under the action of shrinkage elastic force, and the inner ring 131 of the outer seal ring 13 can be installed at different positions in the height direction of the annular inclined wall 111.

By installing the outer seal ring 13 on the annular inclined wall 111, the inner ring 131 of the outer seal ring 13 is attached to the annular inclined wall 111 under the action of self elasticity; as the outer seal ring 13 is positioned at different positions in the height direction of the annular inclined wall 111, the diameter of the annular inclined wall 111 at which the outer seal ring 13 is positioned changes, and thus the diameter of the outer seal ring 13 also changes; that is, the diameter of the outer seal ring 13 increases when the outer seal ring 13 moves upward on the annular inclined wall 111, whereas the diameter of the outer seal ring 13 decreases when the outer seal ring 13 moves downward on the annular inclined wall 111; so that the outer sealing ring 13 is suitable for the inner walls of the water outlet with different sizes, and the sealing effect can be ensured.

The inner ring 131 is attached to the annular inclined wall 111 through friction force, when the position of the outer sealing ring 13 needs to be adjusted, the outer sealing ring 13 is pulled outwards and upwards at the same time, after the hand is loosened, the outer sealing ring 13 at the pulled part moves upwards for a certain distance, and the rest of the outer sealing ring 13 is adjusted in the same way. Downward adjustment pulls outward and downward at the same time.

Preferably, the outer side of the inner ring 131 of the outer seal ring 13 is provided with an integrally formed outer ring 132, and the diameter of the outer ring 132 varies with the installation position of the outer seal ring 13 on the annular inclined wall 111; the outer ring 132 is connected to the middle position outside the inner ring 131. An outer ring body 132 is formed on the outer seal ring 13, and the outer ring body 132 and the inner ring 131 of the outer seal ring 13 are integrally formed. Along with the different positions of the inner ring 131 on the annular inclined wall 111, the diameter of the inner ring 131 is changed, the diameter of the outer ring 132 positioned outside the inner ring 131 is enlarged or reduced, the outer ring 132 and the inner wall of the sewer outlet are deformed during sealing and bonding, and elastic abutting force is arranged between the outer ring 132 and the inner wall of the sewer outlet, so that the sealing effect is ensured.

Preferably, the upper end of the drainer housing 1 is connected with a placement plate 12, and the upper end of the annular inclined wall 111 is connected with the placement plate 12; the outer side wall 11 of the drainer housing 1 further has an outer cylinder 112 located at the lower portion of the annular inclined wall 111, the upper end of the outer cylinder 112 being connected to the lower end of the annular inclined wall 111, the outer diameter of the outer cylinder 112 being smaller than the minimum outer diameter of the annular inclined wall 111. The annular inclined wall 111 is positioned at the upper part of the outer side wall 11 of the drainer, the upper part is connected with the placing plate 12, and the lower part is connected with the outer cylinder 112; when the drainer is installed in the sewer outlet 100 from top to bottom, the outer cylinder 112 is completely plugged into the sewer outlet 100, the placing plate 12 is lapped at the opening of the sewer outlet 100, and the outer sealing ring 13 on the annular inclined wall 111 is sealed with the inner wall of the sewer outlet 100.

The drainer housing 1 is formed by integrally molding a plastic material or a metal material; the annular inclined wall 111 is directly formed during the production of the drainer housing 1, and has a compact structure and low cost.

The degree of tightness of the drainer after being installed in the drain opening 100 can also be adjusted by changing the diameter of the outer seal ring 13 by adjusting the position of the outer seal ring 13. So that the drainer is not driven by the water flow due to excessive loosening between the drainer and the drain opening 100. And the drainer is not difficult to be plugged into the drain opening 100 due to over tightening. As shown in fig. 10, the position of the outer seal ring 13 is moved upward in fig. 10 as compared with the outer seal ring 13 shown by the broken line, so that the diameter of the outer seal ring 13 is increased, and a good seal with the inner wall of the drain opening in the drawing can be ensured (the outer seal ring 13 when the broken line in fig. 10 is the position not adjusted upward, and it can be seen that the outer seal ring 13 shown by the broken line cannot effectively realize the seal). The outer seal ring 13 is made of an elastic material, for example, the outer seal ring 13 is made of a silica gel material.

Preferably, the transverse ribs 61 are provided with second magnets 72, and the deodorizing cover plate 2 is provided with first magnets 71 corresponding to the second magnets 72 one by one; the first and second magnets 71, 72 repel each other. By providing the second magnet 72 on the transverse rib 61 instead of the large magnet provided in the middle, the magnet mounting structure is also simpler by mounting the second magnet 72 on the transverse rib 61. Preferably, the transverse ribs 61 are equally spaced around the axis, so that the repulsive forces between the sets of first and second magnets 71, 72 together constitute an upward force on the deodorant cover plate 2, and a single first magnet 71 may be a smaller magnet. And the equivalent action area of the combination of the action points of the plurality of groups of repulsive force is larger, and the support of the deodorizing closing plate 2 is more stable.

The number of the transverse ribs 61 may be two, three, four, five or six, and preferably the number of the transverse ribs 61 is four. At least two of the transverse ribs 61 are provided with second magnets 72. For example, the second receiving chambers 721 are provided on each of the lateral ribs 61, but the second magnets 72 may not be installed in each of the second receiving chambers 721, and two of the second receiving chambers 721 may be selected to install the second magnets 72 as needed.
