Description

Technical Field

[0001] The utility model relates to the technical field of drainage structures, in particular to a water trap structure and a building drainage system. Background Art

[0002] Traps are key components in high-rise building drainage systems. Their unique collection, absorption, and storage functions gather sewage in pipes, preventing backflow and regulating drainage flow. However, existing traps often face challenges in practical applications, resulting in water seal damage caused by the inability to discharge sewage in a timely manner.

[0003] Trap seal failure primarily manifests in two ways: static and dynamic. Static seal failure primarily occurs in daily life, when impurities such as hair and dust enter sanitary fixtures through drainage and accumulate within the trap. Over time, these impurities gradually clog the trap, reducing the amount of water within. Once the water within the trap completely evaporates or drains away, the static seal is breached, effectively preventing odors and backflow.

[0004] At the same time, the methods for removing pollutants generally require users to hook out pollutants through a very long, retractable wire in the upstream pipeline, or to increase the water pressure to perform punching and removal of pollutants. These methods of removal are still difficult for general users.

[0005] Therefore, the main problem with existing water traps in the drainage system of high-rise buildings is that the water seal is easily damaged due to the difficulty in removing dirt, and it is difficult to perform its function of blocking sewage and odor in a long-term and stable manner, affecting the normal operation of the drainage system and the living experience of residents. Utility Model Content

[0006] The main purpose of the present invention is to provide a water trap structure and a building drainage system, so as to at least solve the problem of water seal damage caused by the inability to discharge sewage in time mentioned in the related art.

[0007] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] In a first aspect of the present invention, a water trap structure is provided, which is applied to a building drainage system. The water trap structure comprises an inlet elbow structure, an intermediate elbow structure and an outlet elbow structure connected in sequence.

[0009] The water inlet elbow structure is used to connect to the water inlet end of the building drainage system, and the water outlet elbow structure is used to connect to the water outlet end of the building drainage system;

[0010] A first fluid cavity is formed inside the water inlet elbow structure, a second fluid cavity is formed inside the middle elbow structure, and a third fluid cavity is formed inside the water outlet elbow structure, wherein the first fluid cavity, the second fluid cavity and the third fluid cavity are sequentially connected;

[0011] A contamination-blocking component is provided in an inner cavity area of the second fluid inner cavity close to the first fluid inner cavity, a contamination-collecting channel is provided in an outer wall area of the intermediate elbow structure, and a distance between the inner cavity area and the outer wall area is less than a preset spacing length;

[0012] Among them, when the water trap structure is in the first working state, when the fluid at the water inlet end enters the water inlet elbow structure, the pollution blocking component blocks pollutants in the fluid flowing into the first fluid inner cavity; when the water trap structure is in the second working state, the sewage collection channel is used to accommodate pollutants discharged from the inner cavity area along the outer wall area to the outside of the water trap structure.

[0013] Based on the first aspect, the pollution-blocking component includes a control mechanism, a rotation mechanism and a pollution-blocking baffle connected to the rotation mechanism; the control mechanism is used to control the rotation of the rotation mechanism, the rotation mechanism is movably connected in the second fluid cavity, and can drive the pollution-blocking baffle to rotate, and the pollution-blocking baffle is used to block pollutants in the fluid flowing into the first fluid cavity.

[0014] Based on the first aspect, the interval length is less than or equal to the radial length of the second fluid cavity in the middle elbow structure.

[0015] On the basis of the first aspect, the sewage extraction channel includes a through hole, and the through hole is a hole formed between the inner wall of the second fluid cavity and the outer wall area of the middle elbow structure.

[0016] The second aspect of the present invention provides a building drainage system, comprising an inlet pipe body, an outlet pipe body and a trap structure as described in the first aspect; the inlet pipe body is connected to the trap structure, and the outlet pipe body is connected to the trap structure.

[0017] The present invention provides a trap structure and a building drainage system, comprising an inlet elbow structure, an intermediate elbow structure, and an outlet elbow structure connected in sequence. The inlet elbow structure is configured to connect to the water inlet of the building drainage system, and the outlet elbow structure is configured to connect to the water outlet of the building drainage system. The inlet elbow structure defines a first fluid cavity, the intermediate elbow structure defines a second fluid cavity, and the outlet elbow structure defines a third fluid cavity. The first, second, and third fluid cavities are sequentially interconnected. A contamination barrier is disposed in an inner region of the second fluid cavity adjacent to the first fluid cavity. An outer wall region of the intermediate elbow structure is configured to provide a contamination removal channel, with the inner cavity region and the outer wall region separated by a distance less than a predetermined spacing length. When the trap structure is in a first operating state, when fluid from the water inlet enters the inlet elbow structure, the contamination barrier blocks contaminants in the fluid flowing from the first fluid cavity. When the trap structure is in a second operating state, the contamination removal channel is configured to receive contaminants discharged from the inner cavity region along the outer wall region to the exterior of the trap structure. Based on the above technical solution, the water trap structure of the present invention, on the one hand, effectively blocks dirt from entering the lower pipe by setting a pollution-blocking component, thereby improving the service life and operation efficiency of the drainage system. On the other hand, there is no need to adopt traditional pollution removal methods that are more difficult, such as using a retractable clamp that extends from the upper pipe to hook out pollutants. By setting a pollution collection channel and based on the distance between the inner cavity area and the outer wall area being less than the preset interval length, the pollutants are removed on the basis of reducing the difficulty of users in removing pollutants, thereby ensuring that pollutants will not be retained in the middle elbow structure, avoiding the static water seal from being destroyed due to the reduction of internal water volume, and improving the stability of the water seal.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0025] It should be noted that relative terms such as "first," "second," etc. may be used to describe various components, but these terms do not limit the components. These terms are only used to distinguish one component from another. For example, without departing from the scope of the present invention, a first component may be referred to as a second component, and a second component may similarly be referred to as a first component. The term "and / or" refers to any one or more combinations of the related items and the described items.

[0026] See also Figure 1 、 Figure 2 and Figure 3 This embodiment provides a water trap structure 1, which is applied to a building drainage system and includes at least an inlet elbow structure 10, an intermediate elbow structure 20 and an outlet elbow structure 30 connected in sequence.

[0027] In this embodiment, the input port 102 of the water inlet elbow structure 10 is used to connect to the water inlet end of the building drainage system, and the output port 302 of the water outlet elbow structure 30 is used to connect to the water outlet end of the building drainage system. The intermediate elbow structure 20 serves as the connecting part between the water inlet elbow structure 10 and the water outlet elbow structure 30 and is based on the large inner cavity space to facilitate the arrangement of corresponding components, further playing the role of preventing pollution, removing pollution, and regulating drainage flow.

[0028] Specifically, a first fluid cavity 101 is formed inside the water inlet elbow structure 10, a second fluid cavity 201 is formed inside the middle elbow structure 20, and a third fluid cavity 301 is formed inside the water outlet elbow structure 30. The first fluid cavity 101, the second fluid cavity 201 and the third fluid cavity 301 are connected in sequence, so that the fluid in the building drainage system can flow into and out of the water trap structure 1 through the first fluid cavity 101, the second fluid cavity 201 and the third fluid cavity 301 in sequence.

[0029] Specifically, a contaminant blocking assembly 50 is provided in the inner cavity region of the second fluid cavity 201 near the first fluid cavity 101, and a contaminant removal channel 40 is provided on the outer wall region of the intermediate elbow structure 20, extending between the second fluid cavity 201 and the exterior of the trap structure 1. Specifically, because the distance between the inner cavity region and the outer wall region is less than a predetermined spacing length, the contaminant blocking assembly 50 is relatively close to the contaminant removal channel 40. Under normal conditions, the contaminant removal channel 40 can accommodate contaminants discharged from the inner cavity region along the outer wall region to the exterior of the trap structure. In other words, a user can use a conventional gripper (such as chopsticks or scissors) to reach into the second fluid cavity 201 through the contaminant removal channel 40 and remove the blocked contaminants (such as hair) from the contaminant removal channel 40, thereby removing the contaminants from the second fluid cavity 201 and completing the contaminant removal process.

[0030] Among them, the trap structure 1 has two working states. When it is in the first working state (conventional fluid passing state), the building drainage system drains water, and when the fluid at the water inlet end enters the water inlet elbow structure, the pollution-blocking component 50 blocks the pollutants in the fluid flowing into the first fluid inner cavity 101; and when the trap structure is in the second working state (conventional pollution removal state), the sewage collection channel 40 provides capacity so that the corresponding pollutants are discharged from the inner cavity area along the outer wall area to the outside of the trap structure, that is, the pollutants can be discharged from the inner cavity area along the sewage collection channel 40 of the outer wall area.

[0031] In combination with the above, the water trap structure of the present invention, on the one hand, effectively blocks dirt from entering the lower pipe by setting up a pollution-blocking component 50, thereby improving the service life and operation efficiency of the drainage system. On the other hand, there is no need to adopt traditional pollution removal methods that are more difficult, such as using a retractable clamp that extends from the upper pipe to hook out pollutants. By setting up a pollution collection channel 40 and based on the distance between the inner cavity area and the outer wall area being less than the preset interval length, pollutants are removed on the basis of reducing the difficulty of users in removing pollutants, thereby ensuring that pollutants will not be retained in the middle elbow structure, avoiding the static water seal from being destroyed due to the reduction of internal water volume, and improving the stability of the water seal.

[0032] In some optional implementations of this embodiment, the spacing length is less than or equal to the radial length of the second fluid lumen in the intermediate elbow structure; if the radial length of the second fluid lumen is L, then the spacing length H≤L, and the corresponding spacing distance G between the inner lumen area and the outer wall area is less than the preset spacing length H. Specifically, by precisely controlling the spacing distance G between the inner lumen area and the outer wall area, primarily controlling the distance between the pollution blocking component 50 and the pollution removal channel 40, the path required for pollutants to be discharged is reduced, allowing pollutants to be discharged smoothly and not easily accumulated, ensuring smooth passage of pollutants and optimizing cleaning efficiency. In addition, more preferably, the spacing length is less than half the radial length of the second fluid lumen in the intermediate elbow structure, that is, H≤(1 / 2)L, and the corresponding spacing distance G between the inner lumen area and the outer wall area is less than (1 / 2)L. By limiting the distance between the pollution blocking component 50 and the pollution removal channel 40, the path required for pollutants to be discharged is further reduced. In special circumstances, manual decontamination can be performed.

[0033] Please continue reading Figure 3 The pollution-blocking assembly 50 includes a control mechanism, a rotating mechanism, and a pollution-blocking baffle 504 connected to the rotating mechanism; the control mechanism is used to control the rotation of the rotating mechanism, the rotating mechanism is movably connected to the second fluid cavity, and can drive the pollution-blocking baffle 504 to rotate, and through the rotation, it has the effect of absorbing and entangling pollutants such as hair in the fluid flowing into the first fluid cavity 101, thereby blocking pollutants in the fluid flowing into the first fluid cavity 101.

[0034] Specifically, the rotation mechanism includes a first rotating member 501, a rod 503, and a second rotating member 502 disposed on the rod 503. The first rotating member 501 and the second rotating member 502 are in meshing engagement. When the control mechanism is activated, the first rotating member 501 rotates, and the second rotating member 502 rotates accordingly based on the meshing relationship. This causes the rod 503 to rotate, driving the dirt blocking baffle 504 to rotate. This rotation, in turn, absorbs and entangles contaminants such as hair in the fluid flowing from the first fluid cavity 101.

[0035] It should be noted that the rod body 503 and the dirt-blocking baffle 504 are detachably connected, for example, by a threaded connection. That is, when the user uses a conventional gripper (chopsticks, scissors, etc.) to reach into the second fluid cavity 201 through the dirt removal channel 40 and is unable to clip out the blocked contaminants (hair, etc.), or when the amount of pollutants accumulated is too large to make them difficult to clip out, the dirt-blocking baffle 504 can be rotated to remove it, thereby simply and conveniently cleaning the contaminants (hair, etc.) stuck in the dirt-blocking baffle 504.

[0036] In some optional implementations of this embodiment, the control mechanism includes a manual control component (not shown in the figure), which is located outside the middle elbow structure and is connected to the slot 5011 of the first rotating member 501 in the rotating mechanism, so that the user can control the rotation of the rotating mechanism by hand shaking or other means.

[0037] In some alternative implementations of this embodiment, the control mechanism includes a motor assembly and a control key for controlling the motor assembly. The output end of the motor assembly is connected to the slot 5011 in the rotation mechanism to drive the rotation thereof. In other words, the user can control the rotation of the rotation mechanism through a key-type control method.

[0038] Please return to Figure 1 , the sewage collection channel 40 includes a through hole, which is a hole formed between the inner wall of the second fluid cavity and the outer wall area of the middle elbow structure; wherein, the through hole, as the core part of the sewage collection channel, ensures that the sewage can be discharged smoothly from the inner cavity, reducing the difficulty of cleaning the pipeline. This design greatly simplifies the maintenance operation of the system, and the user can easily clean it through the channel without disassembling the entire structure. This improves the ease of use of the system and reduces maintenance time and labor costs. In addition, the position and aperture of the sewage collection channel 40 have been optimized to ensure the efficiency of the sewage discharge process. The presence of the through hole allows the sewage to be discharged quickly during the sewage discharge process to avoid accumulation inside the system, further improving the drainage patency and system operation efficiency.

[0039] See also Figure 4 A blocking groove 5042 is provided on the edge of the blocking surface 5041 of the anti-fouling baffle 504 near the rod body 503. The blocking groove 5042 has a certain depth, so that it can block block pollutants (small pieces of soap residue, sand and gravel, etc.); in addition, the blocking surface 5041 on the anti-fouling baffle 504 is also provided with a fluid channel 5043 to ensure the flow of fluid.

[0040] See also Figure 5 The water trap structure also includes a plugging device 60, which covers the through hole. The plugging device 60 is used to prevent external air or foreign matter from entering the system when not in a clean state, thereby ensuring the sealing and safety of the water trap structure.

[0041] Please return to Figure 2In some optional implementations of this embodiment, the pollution-blocking assembly further includes a spring and a baffle; one end of the spring is connected to the pollution-blocking baffle, and the other end of the spring is fixed to an inner cavity region of the second fluid cavity adjacent to the third fluid cavity and is also fixed to the baffle. Specifically, when the trap structure 1 is in a first operating state (i.e., a state allowing normal fluid flow), the spring is in a free state when the rotating mechanism is closed. When the rotating mechanism is opened, the spring contracts and provides a reset force for opening and closing the pollution-blocking baffle, thereby automatically controlling the blocking of pollutants and the passage of fluid.

[0042] A second aspect of the present invention provides a building drainage system, comprising an inlet pipe body, an outlet pipe body and a trap structure; the inlet pipe body is connected to the trap structure, and the outlet pipe body is connected to the trap structure.

[0043] The present invention provides a trap structure and a building drainage system, comprising an inlet elbow structure, an intermediate elbow structure, and an outlet elbow structure connected in sequence. The inlet elbow structure is configured to connect to the water inlet of the building drainage system, and the outlet elbow structure is configured to connect to the water outlet of the building drainage system. The inlet elbow structure defines a first fluid cavity, the intermediate elbow structure defines a second fluid cavity, and the outlet elbow structure defines a third fluid cavity. The first, second, and third fluid cavities are interconnected. A contamination barrier is provided in an inner region of the second fluid cavity adjacent to the first fluid cavity. A contamination removal channel is provided on an outer wall region of the intermediate elbow structure, and a distance between the inner and outer wall regions is less than a predetermined spacing length. When the trap structure is in a first operating state, when fluid from the water inlet enters the inlet elbow structure, the contamination barrier blocks contaminants in the fluid flowing from the first fluid cavity. When the trap structure is in a second operating state, contaminants can be discharged from the inner cavity region along the contamination removal channel on the outer wall region. Based on the above technical solution, the water trap structure of the present invention, on the one hand, effectively blocks dirt from entering the lower pipe by setting a pollution-blocking component, thereby improving the service life and operation efficiency of the drainage system. On the other hand, there is no need to adopt traditional pollution removal methods that are more difficult, such as using a retractable clamp that extends from the upper pipe to hook out pollutants. By setting a pollution collection channel and based on the distance between the inner cavity area and the outer wall area being less than the preset interval length, the pollutants are removed on the basis of reducing the difficulty of users in removing pollutants, thereby ensuring that pollutants will not be retained in the middle elbow structure, avoiding the static water seal from being destroyed due to the reduction of internal water volume, and improving the stability of the water seal.

For those skilled in the art, any equivalent modifications or substitutions made to the utility model are also within the scope of the utility model. Therefore, equivalent changes, modifications, and improvements made without departing from the spirit and scope of the principles of the utility model should be included within the scope of the utility model.
