Automatic drainage mechanism for floor drains and trap boxes

Abstract

An automatic drainage mechanism for floor drains and trap boxes, which is equipped with a grid, a protection ring that surrounds the edge of a core helping to seal and blocking the return of odors and insects, an upper support, a set of magnets, a lower support, a retaining grid that helps block the passage of small animals and a base. Thus, the drainage mechanism, by means of the upper support with the set of magnets and with the lower support create the spring effect in the core, since the set of magnets is divided into arranged on the upper support and arranged on the lower support, in which the magnets are arranged in opposite ways, but with the same polarities facing each other, generating a repulsion between the upper and lower supports.

Description

FIELD OF THE INVENTION

[0001] The present document refers to an automatic drainage mechanism for floor drains and trap boxes, wherein it comprises electromagnetic elements that act as springs, ensuring that the automatic drainage mechanism opens and closes only when necessary, since the drainage mechanism for floor drains and / or trap boxes, operationally, remains in normally closed mode.DISCUSSION OF THE PRIOR ART

[0002] Some types of drains for automatic water drainage are known to the state of the art. One of these types of drains blocks the piping to prevent the access of insects that come from the sewer network, so they are prevented from entering the room through the drain. There are further devices that are composed of a valve containing one or more magnets, whereby the valve opens for the passage of water and at the end of the passage of water the valve closes, blocking access to the sewer network.

[0003] An example of a drain containing a magnet for water outlet and insect containment is presented in patent document BR102017002211-0, in which the drain consists of three parts, namely: grid, grid holder and valve, which is equipped with a magnet placed at the lower end of said valve, whose outlet is closed by a lid equipped with an iron weight that joins the magnet arranged in the valve body. Thus, the drain allows water outlet and remains closed to contain insects or odors that may come from the sewer network. However, the device revealed in the Brazilian document allows a small volume of water to pass through, since it is necessary to accumulate a sufficient amount of water to overcome the electromagnetic force between the magnet arranged in the body of the valve and the iron weight arranged in the lid.

[0004] Another example of the state of the art is document CN216195299, which reveals a floor drain with automatic water sealing comprising an inner floor drain core, a first permanent magnet, a second permanent magnet and a floor drain cover plate. When the gravity of the water in the drain core is greater than the magnetic attraction force between the first and second magnet, the latter slides down and the sealing plate is installed on the second magnet. The second magnet slides down and opens automatically, and the water flow exits therefrom. When the water flow ceases, the gravity of the water acting on the inner core of the floor drain is less than the magnetic attraction force, the second magnet slides upwards, and the sealing plate is closed automatically. Thus, the device can prevent the entry of odors through the sealing plate and the water seal.

[0005] However, the device in the Chinese document features a device that remains permanently fixed and the component that slides into the passage of water is the device inside the drain. Thus, just like the drain in the Brazilian document, this device in the Chinese document has an internal valve for the passage of water, and also as in the Brazilian document it contains a grid with holes on the outside.

[0006] Another example is document CN200982014 which refers to a floor drain to control the start and stop of discharge of a drain by magnetic force which comprises a floor drain base with the discharge hole, a dynamic magnet and a static magnet whereby the magnetic polarity of the opposite face of the dynamic magnet and the static magnet are exclusive, the dynamic magnet and the static magnet being both arranged at the bottom of the discharge hole, the static one being arranged on a support frame and the dynamic magnet being arranged between the discharge hole and the support frame and sealing the discharge hole.

[0007] After the magnetically controlled floor drain is installed, there is no accumulation of water on the floor, and the cover body of the magnet is driven to close the drainage hole under the repulsive force between the magnets. When water accumulates on the floor, the lid can be opened when the gravity of the water is greater than the upward thrust of the magnetic field, so that the water can flow smoothly into the drainpipe. After the water has been drained, the lid will seal the drainage hole again under the action of the repulsive force of the magnetic field, which can prevent the overflow of odors and the entry of reptiles. However, the device has some drawbacks, such as the need for a travel block to rotate and adjust the fixation relation between the protrusion and the groove to achieve the alignment of the cover body with the drainage hole.

[0008] Further, document CN210857455 reveals a floor drain with automatic anti-reverse impact closing. The openings are formed at the top and bottom of the housing. A first-stage sealing mechanism and a second-stage sealing mechanism are arranged sequentially in the shell, from top to bottom. The water flow is first filtered by the filtration mechanism, and next it enters the funnel and hemispherical lid and pushes the first rotary plate to open, so that the water flow is discharged through the water permeation hole on the surface of the partition plate. In a normal state, the first turntable is in a vertical downward state under the action of gravity, and under the action of the permanent magnet, it seals and fits into the opening of the hemispherical lid to effectively prevent overflow.

[0009] However, similar to Brazilian document BR102017002211-0, Chinese document CN210857455 releases the passage of water through a lid which comprises a magnet that closes the valve that is also equipped with a magnet. In addition, the device revealed in the Chinese document comprises two stages, which presents greater complexity in the assembly or maintenance thereof.

[0010] Still found in this field is the so-called intelligent drain which, when activated with a touch by the user, allows water to pass through. Disadvantageously, said device requires activation by the user to allow the passage of water and, therefore, does not work automatically as the present patent document. One of the problems with this model is its fragility, because by depending on the user's activation for opening and closing, this device breaks easily, since it is not possible to measure the intensity of the force applied by each user for the opening and closing of the drain.SUMMARY OF THE INVENTION

[0011] In order to solve the existing problems and present an evolution of the state of the art, this patent document refers to an automatic drainage mechanism for drains and siphon traps.

[0012] Thus, it is an objective to provide a mechanism equipped with a grid, a core, a set of magnets, a lower support, an upper support and a base, being alternatively equipped with a grid that blocks the passage of insects or animals. Thus, part of the set of magnets is arranged on the lower support, while another part of the set of magnets is arranged on the upper support, whereby the parts are arranged in opposite ways, in which equal polarities exert the repulsion between the lower and upper supports, creating the spring effect of the core.

[0013] Another objective is to provide pins, projections, guide channels and holes that guarantee the alignment of the lower and upper supports, in such a way that the magnets continue to interact between their electromagnetic fields, in addition to eliminating the need for position adjustments as in the state of the art.

[0014] Another objective is to provide a sealing medium that helps in sealing to block the return of odors and, simultaneously, covers the edge of the core, ensuring that there are no incidents with users.

[0015] It is a further differential of the present embodiment the automation of the opening and closing of the core, which directly implies the durability of the product, since the operation thereof does not depend on the user's action, that is, the drainage mechanism allows the automatic opening and closing through the weight of the water, enabling the flow of water and that at the end of the flow of water, the drainage mechanism closes automatically, blocking and preventing the access of insects from the sewer network.

[0016] Schematic figures of a particular embodiment of the innovation will be presented below, whose dimensions and proportions are not necessarily the real ones, since the figures have only the purpose of didactically presenting the various aspects thereof, whose scope of protection is determined by the scope of the attached claims.

[0017] In view of this, advantageously, the magnetic device enables an automatic flow of water, and further blocks and prevents the access of insects originating from the sewer network from entering the room through the drain.BRIEF DESCRIPTION OF THE FIGURES

[0027] The object of this document will be better understood in the light of the detailed description that follows in its preferential, but not limiting, embodiment, which has as an illustration the schematic drawings attached.

[0028] Thus, according to FIG. 1, the automatic drainage mechanism (M) is equipped with a grid (1), a core (3), an upper support (4), a set of magnets (5), a lower support (6) and a base (8). Optionally, the drainage mechanism (M) comprises a retaining grid (7) that helps to block the passage of small animals, since it is equipped with openings that allow only water to pass through. Also optionally, the automatic drainage mechanism (M) comprises a protection ring (2) that surrounds the edge of the core (3), which advantageously ensures that there are no incidents with users, and, simultaneously, helps in sealing by blocking the return of odors and insects.

[0029] Still according to FIG. 1, the set of magnets (5) is configured by magnets (5A) which are arranged on the upper support (4), and magnets (5B) arranged on the lower support (6).

[0030] FIGS. 2 and 3 illustrate the upper support (4), which is configured by a first edge (40), at least two first beams (41) that project from the inner face of the first edge (40) to the geometric center of the upper support (4), in which a guide pin (42) is arranged, in which each first beam (41) comprises at least one first housing (410) of magnets (5A) and set of magnets (5).

[0031] In the preferred embodiment, the upper support (4) comprises three first beams (41) that project from the edge (40) joining the guide pin (42) arranged in the geometric center of said upper support (4), however, it will be understood that the number of the first beams (41) may vary according to the diameter of the upper support (4), for instance. Likewise, it will be understood that the amount of first housing (410) of magnets (5A) arranged in each first beam (41) can also vary according to the design, the electromagnetic field or even the diameter of the upper support (4).

[0032] Optionally, each first beam (41) comprises a first through-hole (411) for maintenance, which is arranged over each first housing (410), thus, advantageously, in the event of a need to change the magnets (5A), the user or professional can use the first through-hole (411) to insert an object that may force the magnets out (5A), since these are inserted and fixed in the first housing (410) by means of mechanical interference. Further, optionally, each first beam (41) comprises a stopper (412) of the core (3), so that the stopper (412) ensures that the core (3) remains in the correct position, in addition to ensuring that there is no structural damage to said core (3), since the stopper (412) also performs the function of a support pillar for the perimeter portion of the core (3), as illustrated in FIG. 4A, particularly.

[0033] Alternatively, each first beam (41) comprises two segments arranged in different planes, so that the junction of the two segments promotes greater mechanical resistance and, at the same time, allows the vertical linear movement of the upper support (4). In the same manner, alternatively, the first housing (410) and the magnet (5A) can be configured by a circle, which is arranged around the guide pin (42) creating enough electromagnetic field to exert the spring effect with the lower bracket (6).

[0034] Still according to FIGS. 2 and 3, the first edge comprises at least one guide projection (401) that extends from the outer face of said first edge (40), however the amount can vary, so that preferably the first edge (40) comprises three guide projections (401). Optionally, the first edge (40) further comprises at least one stroke limiter (402) and at least one locking projection (403) of the core (3), wherein each stroke limiter (402) also protrudes from the outer face of said first edge (40) so as to interrupt the stroke of the upper support (4) when the said stroke limiter (402) hits the second edge (60) of the lower support (6), as illustrated in FIG. 7, while each locking projection (403), as illustrated in FIGS. 4 and 4A, is arranged on the upper face and projects towards the center of the first edge (40) creating a spacing for the fitting and locking of the core (3).

[0035] FIGS. 5 and 6 illustrate the lower support (6), which is configured by a second edge (60), at least two second beams (61) that project from the inner face of the second edge (60) towards the geometric center of the lower support (6), in which a guide hole (62) is arranged for receiving the guide pin (42) of the upper support (4), in which each second beam (61) comprises at least one second housing (610) of magnets (5B) and set of magnets (5).

[0036] In the preferred embodiment, the lower support (5) comprises three second beams (61) that project from the edge (60) joining the guide hole (62) arranged in the geometric center of said lower support (6), however, it will be understood that the number of the second beams (61) may vary according to the diameter of the lower support (6), for instance. In the same manner, it will be understood that the amount of second housing (610) of magnets (5B) arranged in each second beam (61) can also vary according to the design, the electromagnetic field or even the diameter of the lower support (6).

[0037] Optionally, each second beam (61) comprises a second through-hole (612) for maintenance, which is arranged over each second housing (610), thus, advantageously, in the event of a need to change the magnets (5B), the user or professional can use the second through-hole (612) to insert an object that may force the magnets out (5B), since these are inserted and fixed in the second housing (610) by means of mechanical interference. Further, optionally, each second beam (61) comprises a structural rib (611) which promotes a load capacity, avoiding structural damage to said structural rib (611), while the second edge (60) comprises at least one guide channel (601) to receive the guide projection (401) of the first edge (40) of the upper support (4), in such a way that the fitting and union of the guide channel (601) with the guide projection (401), ensures that there is no rotating displacement of the upper support (4) in relation to the lower support (6), ensuring that the entire set of magnets (5) remain aligned, causing the electromagnetic fields to interact with each other, as illustrated by FIG. 7.

[0038] Alternatively, each second beam (61) comprises two segments arranged in different planes, so that the junction of the two segments promotes greater mechanical resistance and, simultaneously, allows the vertical linear movement of the lower support (6). In the same manner, alternatively, the second housing (610) and the magnet (5B) can be configured by a circle, which is arranged around the guide channel (601) creating enough electromagnetic field to exert the spring effect with the upper support (4).

[0039] Preferably, the first and second edges (40 and 60), respectively, are configured by the geometric shape of a circle, however, it will be understood that the geometric shape can be non-polygonal such as an ellipse or any polygonal shape, such as square, rectangle, among other shapes.

[0040] Thus, as shown in FIG. 8, the drainage mechanism (M), by means of the set of magnets (5), in such a way that the magnets are divided into (5A) arranged on the upper support (4) and (5B) arranged on the lower support (6), wherein the magnets (5A and 5B) are arranged in opposite ways, but with the same polarities facing each other, generating a repulsion between the upper and lower supports (4 and 6), creating the spring effect in the core (3). Therefore, when the force generated by the mass of water on the core (3) is greater than the repulsion force of the magnets (5A and 5B), the upper support (4) moves linearly and vertically downwards in relation to the lower support (6), allowing the water to drain and, at the end, there being no water on the core (3), the repulsion force causes the upper support (4) to return to its initial position, and the vertical upward linear stroke is limited by means of the stroke limiter (402). This displacement is repeated countless times since the upper and lower supports (4 and 6) comprise guides, pins and channels that guarantee the correct movement, as well as guarantee the alignment of the magnets (5A and 5B) so that the electromagnetic fields continue to interact with each other.

[0041] The person skilled in the art will readily perceive, from the description and the represented drawings, various ways to carry out the invention without departing from the scope of the attached claims.

Optionally, the drainage mechanism (M) comprises a retaining grid (7) that helps to block the passage of small animals, since it is equipped with openings that allow only water to pass through. Also optionally, the automatic drainage mechanism (M) comprises a protection ring (2) that surrounds the edge of the core (3), which advantageously ensures that there are no incidents with users, and, simultaneously, helps in sealing by blocking the return of odors and insects.

[0029]Still according to FIG. 1, the set of magnets (5) is configured by magnets (5A) which are arranged on ...

One of these types of drains blocks the piping to prevent the access of insects that come from the sewer network, so they are prevented from entering the room through the drain. There are further devices that are composed of a valve containing one or more magnets, whereby the valve opens for the passage of water and at the end of the passage of water the valve closes, blocking access to the sewer network.

Thus, the drain allows water outlet and remains closed to contain insects or odors that may come from the sewer network. However, the device revealed in the Brazilian document allows a small volume of water to pass through, since it is necessary to accumulate a sufficient amount of water to overcome the electromagnetic force between the magnet arranged in the body of the valve and the iron weight arranged in the lid.

[0004] Another example of the state of the art is document CN216195299, which reveals a floor drain with automatic water sealing comprising an inner floor drain core, a first permanent magnet, a second permanent magnet and a floor drain cover plate. When the gravity of the water in the drain core is greater than the magnetic attraction force between the first and second magnet, the latter slides down and the sealing plate is installed on the second magnet. The second magnet slides down and opens automatically, and the water flow exits therefrom. When the water flow ceases, the gravity of the water acting on the inner core of the floor drain is less than the magnetic attraction force, the second magnet slides upwards, and the sealing plate is closed automatically. Thus, the device can prevent the entry of odors through the sealing plate and the water seal.

[0005] However, the device in the Chinese document features a device that remains permanently fixed and the component that slides into the passage of water is the device inside the drain. Thus, just like the drain in the Brazilian document, this device in the Chinese document has an internal valve for the passage of water, and also as in the Brazilian document it contains a grid with holes on the outside.

When water accumulates on the floor, the lid can be opened when the gravity of the water is greater than the upward thrust of the magnetic field, so that the water can flow smoothly into the drainpipe. After the water has been drained, the lid will seal the drainage hole again under the action of the repulsive force of the magnetic field, which can prevent the overflow of odors and the entry of reptiles. However, the device has some drawbacks, such as the need for a travel block to rotate and adjust the fixation relation between the protrusion and the groove to achieve the alignment of the cover body with the drainage hole.

[0008] Further, document CN210857455 reveals a floor drain with automatic anti-reverse impact closing. The openings are formed at the top and bottom of the housing. A first-stage sealing mechanism and a second-stage sealing mechanism are arranged sequentially in the shell, from top to bottom.

[0027] The object of this document will be better understood in the light of the detailed description that follows in its preferential, but not limiting, embodiment, which has as an illustration the schematic drawings attached.

[0028] Thus, according to FIG. 1, the automatic drainage mechanism (M) is equipped with a grid (1), a core (3), an upper support (4), a set of magnets (5), a lower support (6) and a base (8). Optionally, the drainage mechanism (M) comprises a retaining grid (7) that helps to block the passage of small animals, since it is equipped with openings that allow only water to pass through. Also optionally, the automatic drainage mechanism (M) comprises a protection ring (2) that surrounds the edge of the core (3), which advantageously ensures that there are no incidents with users, and, simultaneously, helps in sealing by blocking the return of odors and insects.

[0029] Still according to FIG. 1, the set of magnets (5) is configured by magnets (5A) which are arranged on the upper support (4), and magnets (5B) arranged on the lower support (6).

[0030] FIGS. 2 and 3 illustrate the upper support (4), which is configured by a first edge (40), at least two first beams (41) that project from the inner face of the first edge (40) to the geometric center of the upper support (4), in which a guide pin (42) is arranged, in which each first beam (41) comprises at least one first housing (410) of magnets (5A) and set of magnets (5).

[0031] In the preferred embodiment, the upper support (4) comprises three first beams (41) that project from the edge (40) joining the guide pin (42) arranged in the geometric center of said upper support (4), however, it will be understood that the number of the first beams (41) may vary according to the diameter of the upper support (4), for instance. Likewise, it will be understood that the amount of first housing (410) of magnets (5A) arranged in each first beam (41) can also vary according to the design, the electromagnetic field or even the diameter of the upper support (4).

[0032] Optionally, each first beam (41) comprises a first through-hole (411) for maintenance, which is arranged over each first housing (410), thus, advantageously, in the event of a need to change the magnets (5A), the user or professional can use the first through-hole (411) to insert an object that may force the magnets out (5A), since these are inserted and fixed in the first housing (410) by means of mechanical interference. Further, optionally, each first beam (41) comprises a stopper (412) of the core (3), so that the stopper (412) ensures that the core (3) remains in the correct position, in addition to ensuring that there is no structural damage to said core (3), since the stopper (412) also performs the function of a support pillar for the perimeter portion of the core (3), as illustrated in FIG. 4A, particularly.

[0033] Alternatively, each first beam (41) comprises two segments arranged in different planes, so that the junction of the two segments promotes greater mechanical resistance and, at the same time, allows the vertical linear movement of the upper support (4). In the same manner, alternatively, the first housing (410) and the magnet (5A) can be configured by a circle, which is arranged around the guide pin (42) creating enough electromagnetic field to exert the spring effect with the lower bracket (6).

[0034] Still according to FIGS. 2 and 3, the first edge comprises at least one guide projection (401) that extends from the outer face of said first edge (40), however the amount can vary, so that preferably the first edge (40) comprises three guide projections (401). Optionally, the first edge (40) further comprises at least one stroke limiter (402) and at least one locking projection (403) of the core (3), wherein each stroke limiter (402) also protrudes from the outer face of said first edge (40) so as to interrupt the stroke of the upper support (4) when the said stroke limiter (402) hits the second edge (60) of the lower support (6), as illustrated in FIG. 7, while each locking projection (403), as illustrated in FIGS. 4 and 4A, is arranged on the upper face and projects towards the center of the first edge (40) creating a spacing for the fitting and locking of the core (3).

[0035] FIGS. 5 and 6 illustrate the lower support (6), which is configured by a second edge (60), at least two second beams (61) that project from the inner face of the second edge (60) towards the geometric center of the lower support (6), in which a guide hole (62) is arranged for receiving the guide pin (42) of the upper support (4), in which each second beam (61) comprises at least one second housing (610) of magnets (5B) and set of magnets (5).

[0036] In the preferred embodiment, the lower support (5) comprises three second beams (61) that project from the edge (60) joining the guide hole (62) arranged in the geometric center of said lower support (6), however, it will be understood that the number of the second beams (61) may vary according to the diameter of the lower support (6), for instance. In the same manner, it will be understood that the amount of second housing (610) of magnets (5B) arranged in each second beam (61) can also vary according to the design, the electromagnetic field or even the diameter of the lower support (6).

[0037] Optionally, each second beam (61) comprises a second through-hole (612) for maintenance, which is arranged over each second housing (610), thus, advantageously, in the event of a need to change the magnets (5B), the user or professional can use the second through-hole (612) to insert an object that may force the magnets out (5B), since these are inserted and fixed in the second housing (610) by means of mechanical interference. Further, optionally, each second beam (61) comprises a structural rib (611) which promotes a load capacity, avoiding structural damage to said structural rib (611), while the second edge (60) comprises at least one guide channel (601) to receive the guide projection (401) of the first edge (40) of the upper support (4), in such a way that the fitting and union of the guide channel (601) with the guide projection (401), ensures that there is no rotating displacement of the upper support (4) in relation to the lower support (6), ensuring that the entire set of magnets (5) remain aligned, causing the electromagnetic fields to interact with each other, as illustrated by FIG. 7.

[0038] Alternatively, each second beam (61) comprises two segments arranged in different planes, so that the junction of the two segments promotes greater mechanical resistance and, simultaneously, allows the vertical linear movement of the lower support (6). In the same manner, alternatively, the second housing (610) and the magnet (5B) can be configured by a circle, which is arranged around the guide channel (601) creating enough electromagnetic field to exert the spring effect with the upper support (4).

[0039] Preferably, the first and second edges (40 and 60), respectively, are configured by the geometric shape of a circle, however, it will be understood that the geometric shape can be non-polygonal such as an ellipse or any polygonal shape, such as square, rectangle, among other shapes.

[0040] Thus, as shown in FIG. 8, the drainage mechanism (M), by means of the set of magnets (5), in such a way that the magnets are divided into (5A) arranged on the upper support (4) and (5B) arranged on the lower support (6), wherein the magnets (5A and 5B) are arranged in opposite ways, but with the same polarities facing each other, generating a repulsion between the upper and lower supports (4 and 6), creating the spring effect in the core (3). Therefore, when the force generated by the mass of water on the core (3) is greater than the repulsion force of the magnets (5A and 5B), the upper support (4) moves linearly and vertically downwards in relation to the lower support (6), allowing the water to drain and, at the end, there being no water on the core (3), the repulsion force causes the upper support (4) to return to its initial position, and the vertical upward linear stroke is limited by means of the stroke limiter (402). This displacement is repeated countless times since the upper and lower supports (4 and 6) comprise guides, pins and channels that guarantee the correct movement, as well as guarantee the alignment of the magnets (5A and 5B) so that the electromagnetic fields continue to interact with each other.

[0041] The person skilled in the art will readily perceive, from the description and the represented drawings, various ways to carry out the invention without departing from the scope of the attached claims.
