Description

Technical Field

[0001] This utility model relates to the technical field of pipelines, and in particular to a pipeline odor prevention device with high sealing performance. Background Technology

[0002] Odor-proof devices for pipes are mainly used to prevent odors from escaping from sewers, ventilation ducts, etc. Common types include mechanical seal type, water seal type, and fiberglass pipe type. Existing odor-proof devices, such as the one disclosed in Chinese Patent (Authorization Announcement No. CN222206644U), include an odor-proof cover, a main body, and a reset mechanism. The main body has an interconnected receiving interface and a drain outlet. The odor-proof cover is rotatably mounted on the pipe body, rotatably switching between a closed drain outlet and an open drain outlet state. The reset mechanism drives the odor-proof cover to the closed drain outlet state. Its key feature is that when the odor-proof cover closes the drain outlet, it is in a horizontal state. Another example is a novel odor-proof floor drain for washing machine drain pipes disclosed in Chinese Patent (Authorization Announcement No. CN219364870U), which includes a top cover with a connecting pipe fixedly connected to its surface. A limit tube is fixedly sleeved on the outer surface of the connecting pipe. This invention, through the installation of a water pipe, a fixed base, and a rotating shaft, allows the floor drain to function effectively. During drainage, the water flow opens the sealing cover and discharges. When drainage ceases, the elasticity of the reset block causes the rotating shaft to return to its original position, automatically closing the sealing cover onto the surface of the water pipe. This isolates the floor drain from the pipe, preventing odor leakage and providing good odor prevention. However, existing odor-preventing pipe devices have only a moderate sealing effect with the upstream pipe, resulting in some odor still escaping from the connection gap between the upstream pipe and the odor-preventing pipe device. Summary of the Invention

[0003] The purpose of this invention is to provide a high-sealing-performance pipe odor prevention device. By designing the sealing sleeve as a tapered section with an increasing outer diameter from bottom to top, when the connecting sleeve is threadedly connected to the pipe body, the sealing sleeve can be squeezed towards the center of the pipe body to clamp the upstream pipe inserted into the socket, thereby achieving a better sealing effect.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a high-sealing-performance pipe odor prevention device, comprising a pipe body and an odor prevention cover plate, wherein the pipe body is provided with a socket and a drain outlet that are interconnected, the odor prevention cover plate is rotatably set at the position of the drain outlet on the pipe body and can rotate between the position of sealing the drain outlet and the position of opening the drain outlet, and the odor prevention cover plate is held in the position of sealing the drain outlet under the action of a reset mechanism, the pipe odor prevention device also includes a sealing sleeve, a sealing ring and a connecting sleeve, the sealing sleeve is fitted inside the socket, the pipe body is provided with a limiting step for limiting the sealing sleeve, the sealing sleeve has a tapered section with an increasing outer diameter from bottom to top, the pipe body is provided with an external threaded part on the outer periphery corresponding to the socket, the connecting sleeve is threadedly connected to the pipe body through the external threaded part, thereby squeezing the sealing sleeve toward the center of the pipe body to clamp the upstream pipe inserted into the socket, the sealing ring is fitted at the lower end of the pipe body, and the pipe body is connected to the downstream pipe through the sealing ring.

[0005] Furthermore, the lower end face of the sealing sleeve is provided with an annular groove, the lower end of which penetrates the lower end face of the sealing sleeve, so that the inner and outer ends of the corresponding annular grooves of the sealing sleeve form a concentric ring structure.

[0006] Furthermore, the sealing sleeve includes an integrally formed vertical section and a tapered section. The diameter of the socket matches the vertical section, and the outer diameter of the tapered section is larger than the diameter of the socket.

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0020] like Figures 1-4As shown, a high-sealing-performance pipe odor prevention device includes a pipe body 10 and an odor prevention cover 20. The pipe body 10 is provided with a receiving port and a drain outlet that are interconnected. The odor prevention cover 20 is rotatably disposed at the position of the drain outlet on the pipe body 10 and can rotate between the position of sealing the drain outlet and the position of opening the drain outlet. Under the action of the reset mechanism, the odor prevention cover 20 is in a state of being held in the position of sealing the drain outlet. The odor prevention cover 20 and the reset mechanism are prior art and will not be described in detail in this application. For details, please refer to the pipe odor prevention device disclosed in Chinese Patent (Authorization Announcement No. CN222206644U).

[0021] The odor-proof device for pipes in this application also includes a sealing sleeve 30, a sealing ring 40, and a connecting sleeve 50. The sealing sleeve 30 is fitted inside the socket. A limiting step 11 is provided inside the pipe body 10 to limit the axial position of the sealing sleeve 30. The sealing sleeve 30 has a tapered section 31 with an increasing outer diameter from bottom to top. The pipe body 10 has an external threaded portion 12 on the outer periphery corresponding to the socket. The connecting sleeve 50 is threadedly connected to the external threaded portion 12. When the connecting sleeve 50 is threadedly connected to the pipe body 10, it can squeeze the sealing sleeve 30 toward the center of the pipe body 10 to clamp the upstream pipe inserted into the socket. The sealing ring 40 is fitted at the lower end of the pipe body 10. The pipe body 10 is connected to the downstream pipe through the sealing ring 40. Specifically, the outer periphery of the pipe body 10 corresponding to the socket is a thin-walled structure, so that when the connecting sleeve 50 is threadedly connected to the threaded part of the pipe body 10, the connecting sleeve 50 can squeeze the outer periphery of the socket of the pipe body 10 inward, thereby squeezing the sealing sleeve 30 inside the socket inward to firmly clamp the upstream pipe.

[0022] The connection steps between the odor-proof device and the upstream pipe are as follows: 1. First, install the sealing sleeve 30 into the socket; 2. Pre-install the connecting sleeve 50 and the pipe body 10; 3. Insert the upstream pipe into the sealing sleeve 30; 4. Thread the connecting sleeve 50 to the pipe body 10. The inner wall of the socket of the pipe body 10, under the action of the connecting sleeve 50, squeezes the sealing sleeve 30, causing it to deform and fit tightly against the upstream pipe, thus achieving a better sealing effect.

[0023] In some embodiments, the lower end face of the sealing sleeve 30 is provided with an annular groove 321, the lower end of the annular groove 321 penetrating the lower end face of the sealing sleeve 30, so that the inner and outer ends of the corresponding annular groove 321 of the sealing sleeve 30 form a concentric ring structure. Through this arrangement, the lower end of the sealing sleeve 30 has better deformation capability, thereby facilitating the insertion of the sealing sleeve 30 into the socket and better fitting with the upstream pipeline under the compression of the socket.

[0024] In some embodiments, the sealing sleeve 30 includes an integrally formed vertical section 32 and a tapered section 31. The vertical section 32 is disposed at the lower part of the tapered section 31. The diameter of the socket matches the vertical section 32. The outer diameter of the tapered section 31 is larger than the diameter of the socket. The tapered section 31 and the vertical section 32 form an insertion channel that matches the upstream pipe. The tapered section 31 is squeezed towards the center of the pipe body 10 under the action of the inner wall of the socket, thereby clamping the upstream pipe more tightly and improving its sealing effect.

[0025] In some embodiments, a toothed portion 13 is provided on the inner wall of the receiving interface at the position corresponding to the upper end of the limiting step 11. The toothed portion 13 is clamped on the outer wall of the vertical section 32. The toothed portion 13 can provide a clamping force to the sealing sleeve 30 so that the sealing sleeve 30 is not easily detached from the receiving interface, that is, it plays a positioning role for the sealing sleeve 30.

[0026] In some embodiments, an installation groove 14 is provided at the middle position of the pipe body 10, and a sealing ring 40 is sleeved on the outer periphery of the installation groove 14. The pipe body 10 is provided with an upper limit part 15 and a lower limit part 16 at both ends corresponding to the installation groove 14. The upper limit part 15 and the lower limit part 16 limit the sealing ring 40 axially. This arrangement can position the sealing ring 40 and prevent its axis from moving.

[0027] In some embodiments, the pipe body 10 is provided with a connecting port that connects the receiving interface and the drain outlet, the limiting step 11 is formed between the receiving interface and the connecting port, and the inner wall of the sealing sleeve 30 is closer to the center of the pipe body 10 than the inner wall of the connecting port.

[0028] In summary, this utility model has the following beneficial effects: The pipe odor prevention device of this utility model is designed with a sealing sleeve 30 having a tapered section 31 with an increasing outer diameter from bottom to top. When the connecting sleeve 50 is threadedly connected to the pipe body 10, the sealing sleeve 30 can be squeezed towards the center of the pipe body 10 to clamp the upstream pipe inserted into the socket, thereby achieving a better sealing effect. Moreover, the pipe odor prevention device has a simple structure and is easy to assemble.

[0029] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
