Description

Technical Field

[0001] This utility model relates to the field of vent plugging technology, specifically to a device for plugging the exhaust vent of an air conditioning duct. Background Technology

[0002] In the daily operation of a hospital, the air conditioning system is one of the key facilities for ensuring a comfortable indoor environment, maintaining the normal operation of medical equipment, and providing a good medical and working environment for patients and medical staff. The normal operation of the air conditioning system depends on a well-functioning drainage system. The function of the drainage pipes is to smoothly discharge liquids such as condensate generated during the operation of the air conditioning system, preventing problems such as water accumulation and leakage. During the drainage process, the multiple vents on the drainage pipes leave them exposed, allowing dust, debris, and potentially microorganisms from the air to easily enter the pipes.

[0003] These debris accumulate gradually inside the pipes, and over time, the buildup increases until the pipes become clogged. Therefore, it is necessary to clean the drainage pipes regularly.

[0004] The existing cleaning method involves first blocking all the vents in the drain pipe with cloth, and assigning one person to block each vent by hand. Then, high-pressure nitrogen is injected into the drain pipe to force it open using the gas pressure. While this method can solve the blockage problem to some extent, it poses certain safety hazards. For example, improper operation of the high-pressure gas may result in personnel injury or equipment damage. Furthermore, this method of blocking vents is inefficient and labor-intensive. Utility Model Content

[0005] The purpose of this invention is to provide a device for blocking the exhaust vent of an air conditioning duct, which can be used to block the exhaust vent, eliminating the need for manual sealing, saving manpower, and having high operational safety.

[0006] To achieve the above objectives, this utility model provides an air conditioning duct exhaust hole blocking device, which includes a sealing structure and a fixing structure; the sealing structure is elastic and can extend into the opening of the exhaust pipe to block the opening; the fixing structure is connected to the sealing structure and has a pressing part; when the sealing structure blocks the opening, the peripheral surface of the sealing structure presses against the inner wall of the exhaust pipe, and the pressing part can press against the outer peripheral surface of the exhaust pipe to clamp the pipe wall of the exhaust pipe together with the sealing structure, and when the sealing structure is removed from the opening, the pressing part can move away from the outer peripheral surface of the exhaust pipe.

[0007] In some embodiments, the fixing structure includes a fixing cover and a surrounding portion spaced around the sealing structure, the sealing structure and the surrounding portion being connected to a first plane of the fixing cover; a pressing portion is provided on the surrounding portion and is capable of moving relative to the surrounding portion toward or away from the sealing structure.

[0008] In some embodiments, the surrounding portion is a cylinder with multiple grooves, one end of the cylinder is connected to a first plane, the grooves extend from the other end of the cylinder to one end and divide one end of the cylinder into multiple spaced arc-shaped portions; the pressing portion is provided on the arc-shaped portion.

[0009] In some embodiments, the number of grooves is two, and they are disposed opposite each other on the cylinder.

[0010] In some embodiments, the pressing part is a locking bolt, which passes through the arc-shaped part and can move toward or away from the sealing structure to clamp or release the pipe wall of the exhaust pipe together with the sealing structure.

[0011] In some embodiments, there are two pressing parts, which are respectively located on two arc-shaped parts.

[0012] In some embodiments, the two pressing portions are symmetrically arranged about the line connecting the two grooves.

[0013] In some embodiments, the sealing structure includes a resilient cylindrical sealing plug, one end of which is connected to a first plane, and the diameter of the cylindrical sealing plug is between 1.02 and 1.05 times the diameter of the opening.

[0014] In some embodiments, the end face of the other end of the cylindrical sealing plug is provided with a frustum coaxial with it. The diameter of the frustum gradually decreases from one end to the other end of the cylindrical sealing plug, and the maximum diameter of the frustum is consistent with the diameter of the cylindrical sealing plug.

[0015] In some embodiments, the first plane is provided with a soft rubber gasket, which is connected around the circumferential surface of the cylindrical sealing plug. When the cylindrical sealing plug blocks the opening, the soft rubber gasket can press against the annular surface of the exhaust pipe and work together with the cylindrical sealing plug to seal the opening.

[0016] The above-mentioned technical solution of this utility model has the following beneficial effects:

[0017] When sealing the opening of the exhaust pipe, the operator inserts the sealing structure into the opening and then presses the pressure part against the outer circumference of the exhaust pipe. The pressure part and the sealing structure together clamp the pipe wall, thus fixing the air conditioning duct exhaust hole plugging device in the exhaust pipe. After cleaning the drain pipe, simply remove the pressure part from the exhaust pipe and pull the sealing structure out of the opening to remove the air conditioning duct exhaust hole plugging device from the exhaust pipe. Therefore, the technical solution of this utility model allows the air conditioning duct exhaust hole plugging device to stably seal the opening during the cleaning process of the exhaust pipe, eliminating the need for excessive manpower, and offering simple operation and high safety.

[0023] The specific embodiments of this utility model are described in detail below. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0025] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of the utility model described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0026] like Figure 1-3 As shown, this utility model provides an air conditioning duct exhaust hole blocking device, which includes a sealing structure 1 and a fixing structure 2. The sealing structure 1 is elastic and can extend into the opening 31 of the exhaust pipe 3 to block the opening 31. The fixing structure 2 is connected to the sealing structure 1 and has a pressing part 21. When the sealing structure 1 blocks the opening 31, the peripheral surface of the sealing structure 1 presses against the inner wall of the exhaust pipe 3, and the pressing part 21 can press against the outer peripheral surface of the exhaust pipe 3 to clamp the pipe wall of the exhaust pipe 3 together with the sealing structure 1. When the sealing structure 1 is removed from the opening 31, the pressing part 21 can move away from the outer peripheral surface of the exhaust pipe 3.

[0027] Specifically, when sealing the opening 31 of the exhaust pipe 3, the operator can insert the sealing structure 1 into the opening 31 of the exhaust pipe 3, and then press the pressing part 21 against the outer circumferential surface of the exhaust pipe 3, so that the pressing part 21 and the sealing structure 1 together clamp the pipe wall of the exhaust pipe 3, thereby fixing the air conditioning pipe exhaust hole blocking device in the exhaust pipe 3. After the drainage pipe 5 is cleaned, simply move the pressing part 21 away from the exhaust pipe 3, and then pull the sealing structure 1 out of the opening 31 to remove the air conditioning pipe exhaust hole blocking device from the exhaust pipe 3. Therefore, by adopting the technical solution of this utility model, the air conditioning pipe exhaust hole blocking device can stably seal the opening 31 by itself during the cleaning process of the exhaust pipe 3, without wasting too much manpower, and is simple to operate and highly safe.

[0028] In some embodiments of this utility model, the fixing structure 2 includes a fixing cover 23 and a surrounding portion 22 spaced around the periphery of the sealing structure 1. The sealing structure 1 and the surrounding portion 22 are connected to the first plane 4 of the fixing cover 23. The pressing portion 21 is provided on the surrounding portion 22 and can move relative to the surrounding portion 22 toward or away from the sealing structure 1.

[0029] Specifically, when the air conditioning duct exhaust hole blocking device blocks the exhaust pipe 3, the pipe wall of the exhaust pipe 3 is placed in the gap between the surrounding part 22 and the sealing structure 1, and the pressing part 21 moves toward the sealing structure 1 until the pressing part 21 presses against the outer peripheral surface of the exhaust pipe 3, so that the pressing part 21 cooperates with the sealing structure 1 to clamp the pipe wall of the exhaust pipe 3, thereby enabling the air conditioning duct exhaust hole blocking device to be stably installed on the exhaust pipe 3, preventing the sealing structure 1 from being blown out of the opening 31 of the exhaust pipe 3 when high-pressure nitrogen is used for cleaning.

[0030] In some embodiments of this utility model, the surrounding part 22 is a cylinder with multiple grooves 221. One end of the cylinder is connected to the first plane 4. The grooves 221 extend from the other end of the cylinder to one end and divide one end of the cylinder into multiple spaced arc-shaped parts 222. The pressing part 21 is provided on the arc-shaped part 222.

[0031] Specifically, when the air conditioning duct exhaust port blocking device blocks the exhaust pipe 3, the cylinder is sleeved on the outer circumference of the exhaust pipe 3. The groove 221 provided on the cylinder provides a certain adjustable space for the diameter of the cylinder, so that the sealing structure 1 can be easily and quickly inserted into the opening 31. The pressing part 21, which is movably provided on the arc-shaped part 222, can move toward or away from the sealing structure 1 to clamp or release the exhaust pipe 3.

[0032] In some embodiments of this utility model, there are two grooves 221, which are arranged opposite to each other on the cylinder.

[0033] Specifically, the grooves 221 of the cylinder are symmetrically arranged, and the cylinder wall is divided into two opposing arc-shaped portions 222. The number of grooves 221 is set to two, which ensures that the cylinder has reliable rigidity while ensuring that the cylinder diameter is slightly adjustable. This allows the pressure part 21 to move towards or away from the sealing structure 1 multiple times, thereby improving the service life of the air conditioning duct exhaust hole blocking device.

[0034] In some embodiments of this utility model, the pressing part 21 is a locking bolt 211, which passes through the arc-shaped part 222 and can move toward or away from the sealing structure 1 to clamp or release the pipe wall of the exhaust pipe 3 together with the sealing structure 1.

[0035] In some embodiments of this utility model, there are two pressing parts 21, and the two pressing parts 21 are respectively provided on two arc-shaped parts 222.

[0036] Specifically, when the sealing structure 1 blocks the opening 31, the two pressing parts 21 can press against the outer circumferential surface of the exhaust pipe 3, and a tight clamping force is formed between the sealing structure 1 and the pipe wall of the exhaust pipe 3, thereby effectively preventing the sealing structure 1 from loosening or shifting during use.

[0037] In some embodiments of this utility model, the two pressing parts 21 are symmetrically arranged about the line connecting the two grooves 221.

[0038] Specifically, this opposing pressure design allows the clamping force to be evenly distributed on the outer circumference of the exhaust pipe 3, preventing damage to the exhaust pipe 3 due to excessive localized force. Furthermore, the symmetrical arrangement of the two pressure points 21 makes the entire device more balanced and stable during operation, facilitating installation and disassembly by maintenance personnel and improving work efficiency.

[0039] In some embodiments of this utility model, the sealing structure 1 includes an elastic cylindrical sealing plug 12, one end of which is connected to the first plane 4. In order to enable the cylindrical sealing plug 12 to achieve a good sealing effect, the diameter of the cylindrical sealing plug 12 is between 1.02 and 1.05 times the diameter of the opening 31. Since the cylindrical sealing plug 12 is elastic, it can be pressed into the opening 31 by applying force when the operator installs it.

[0040] In some embodiments of this utility model, in order to make it easier for the cylindrical sealing plug 12 to enter the opening 31, the end face of the other end of the cylindrical sealing plug 12 is provided with a frustum 11 coaxial with it. In the direction from one end to the other end of the cylindrical sealing plug 12, the diameter of the frustum 11 gradually decreases, and the maximum diameter of the frustum 11 is consistent with the diameter of the cylindrical sealing plug 12.

[0041] In some embodiments of this utility model, in order to achieve a better sealing effect, the first plane 4 is provided with a soft rubber gasket 41, which is connected around the circumferential surface of the cylindrical sealing plug 12. When the cylindrical sealing plug 12 blocks the opening 31, the soft rubber gasket 41 can press against the annular surface of the exhaust pipe 3 and work together with the cylindrical sealing plug 12 to seal the opening 31.

[0042] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0043] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0044] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
