Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical module cleaning technology, and in particular to an optical module dust removal device. Background Technology
[0002] Optical modules, as core components in optical communication networks, are widely used in data centers, base station transmission, and fiber optic access. During routine equipment maintenance, idle optical modules often accumulate dust inside their cavities due to prolonged disuse. This dust severely affects the cleanliness of the optical interface, leading to increased insertion loss, decreased optical signal quality, and even communication interruptions.
[0003] Currently, the industry mainly relies on the following methods for cleaning the cavity holes of optical modules:
[0004] Manual air blowing method: Use a handheld air blower or compressed air can to blow air into the optical module cavity to clean it. This method is simple and easy to do, but the airflow direction is towards the inside of the optical module cavity, which can easily blow dust further into the optical module and cause secondary pollution.
[0005] Cleaning with a dedicated cleaning pen or cotton swabs: Use a cleaning pen with a precision fiber tip or cotton swabs dipped in cleaning solution to wipe the surface. This method requires a high level of skill from the operator, and improper operation may scratch the optical surface of the optical module. Utility Model Content
[0006] The technical problem to be solved by this utility model is to address the above-mentioned shortcomings of the existing technology by providing a dust removal device for optical modules that can remove dust from the cavity of optical modules and avoid secondary pollution and damage caused during the cleaning of optical modules.
[0007] This utility model provides a dust removal device for optical modules, comprising a housing, an air guiding assembly, a handle, and an air guiding pipe. A sealed air guiding cavity is formed within the housing, having an inlet and an outlet positioned opposite each other. The air guiding assembly includes a first gear and a second gear that mesh with each other; both the first gear and the second gear are disposed within the air guiding cavity and located between the inlet and the outlet; when the first gear and the second gear rotate, the gas within the air guiding cavity flows from the inlet to the outlet. The handle is mounted on the housing and passes through the housing, driving the first gear to rotate, thereby causing the second gear to rotate synchronously. The air guiding pipe is mounted on the housing, and its outlet communicates with the inlet of the air guiding cavity.
[0008] In some embodiments, the number of teeth of the first gear is greater than the number of teeth of the second gear.
[0009] In some embodiments, the ratio of the number of teeth of the first gear to the number of teeth of the second gear is n, where 2≤n≤4.
[0010] In some embodiments, the module of both the first gear and the second gear is a, where 0.4mm ≤ a ≤ 0.6mm.
[0011] In some embodiments, the inlet of the air duct is adapted to the interface of the optical module so that the inlet of the air duct can be inserted into the interface of the optical module.
[0012] In some embodiments, the air duct is detachably mounted on the housing.
[0013] In some embodiments, the optical module dust removal device further includes a dust filter bag, which is disposed on the housing and fitted over the air outlet of the air guide cavity to collect dust in the gas discharged from the air outlet.
[0014] In some embodiments, the material of the dust filter bag includes a microporous membrane material, wherein the pore size of the microporous membrane material is less than 1 μm.
[0015] In some embodiments, the dust filter bag is provided with a transparent viewing window.
[0016] In some embodiments, the dust filter bag is detachably mounted on the housing.
[0017] Therefore, the optical module dust removal device provided in this embodiment of the invention, by setting a housing and an air guiding assembly, forms a sealed air guiding cavity within the housing, with an air inlet and an outlet positioned opposite each other. The first gear and the second gear of the air guiding assembly are both located within the air guiding cavity, between the air inlet and the outlet. When the first and second gears rotate, the gas in the air guiding cavity flows from the air inlet to the outlet. A handle is provided on the housing, passing through the housing and connected to the first gear. Rotating the handle drives the first gear to rotate, thereby driving the second gear to rotate synchronously. This creates a pressure difference between the two sides of the first and second gears, and under the action of this pressure difference, an airflow is formed between the air inlet and the outlet of the air guiding cavity. Furthermore, by installing an air duct on the housing, connecting the outlet of the air duct to the inlet of the air duct cavity, when dust removal of the optical module is required, the inlet of the air duct can be aligned with the cavity of the optical module, and the handle can be turned to draw air into the cavity of the optical module through the inlet of the air duct. This generates a turbulent airflow within the cavity of the optical module, carrying away the dust inside. This optical module dust removal equipment is simple to operate, achieving dust removal through airflow without the need to wipe the optical module, thus avoiding damage to the optical module. Moreover, because the airflow direction within the optical module cavity is from the inside out, compared to existing technologies, it avoids further blowing dust into the optical module and causing secondary pollution.

[0027] Example 1:
[0028] like Figure 1 As shown in the figure, this utility model embodiment provides an optical module dust removal device, which is applied in the optical module maintenance process to remove dust from the optical module.
[0029] like Figure 1 and Figure 2 As shown, the optical module dust removal device includes a housing 1, an air guide pipe 4, an air guide assembly, and a handle 7. A sealed air guide chamber 9 is formed within the housing 1, with an air inlet 2 and an air outlet 3 arranged opposite to each other. The air guide assembly includes a first gear 5 and a second gear 6 that mesh with each other. Both the first gear 5 and the second gear 6 are disposed within the air guide chamber 9 and located between the air inlet 2 and the air outlet 3; when the first gear 5 and the second gear 6 rotate, the gas in the air guide chamber 9 flows from the air inlet 2 to the air outlet 3. The handle 7 is mounted on the housing 1 and passes through the housing 1, connecting to the first gear 5 for transmission. It is used to drive the first gear 5 to rotate, thereby driving the second gear 6 to rotate synchronously. The air guide pipe 4 is mounted on the housing 1, and the outlet of the air guide pipe 4 is connected to the air inlet 2 of the air guide chamber 9.
[0030] For example, the material of the housing 1 can be plastic, such as transparent plastic, which can reduce the production cost of the housing 1.
[0031] like Figure 2 As shown, the air inlet 2 and the air outlet 3 are located at opposite ends of the air guide chamber 9.
[0032] The air duct 4 can be a flexible tube that can deform, making it convenient for staff to insert the air duct 4 into the cavity of the optical module.
[0033] For example, the air duct 4 can be fixed to the housing 1 by insertion. The inner diameter of the air duct 4 is 1.5 mm.
[0034] like Figure 2 As shown, the first gear 5 and the second gear 6 are arranged vertically in sequence.
[0035] Understandably, when the first gear 5 and the second gear 6 rotate synchronously, a negative pressure is formed on one side of the first gear 5 and the second gear 6, and a positive pressure is formed on the other side. Under the action of the pressure difference between the two sides, the gas in the air guide chamber 9 flows. Its working principle is similar to that of a gear pump, which is understandable to those skilled in the art. When the gas in the air guide chamber 9 flows from the air inlet 2 to the air outlet 3, it can be drawn in through the inlet of the air guide pipe 4.
[0036] For example, the handle 7 can be directly connected to the shaft of the first gear 5.
[0037] With the above setup, when dust removal from the optical module is required, simply align the inlet of the air duct 4 with the cavity of the optical module, turn the handle, and air will be drawn in through the inlet of the air duct 4. This creates a turbulent airflow within the cavity of the optical module, carrying away the dust inside. This optical module dust removal equipment is simple to operate, achieving dust removal through airflow, which avoids damage to the optical module. Furthermore, because the airflow direction within the optical module cavity is from the inside out, compared to existing technologies, it avoids blowing dust further into the optical module and causing secondary pollution.
[0038] Therefore, the optical module dust removal device provided in this embodiment of the present invention, by setting a housing 1 and an air guiding assembly, forms a sealed air guiding cavity 9 within the housing 1, with the air guiding cavity 9 having an air inlet 2 and an air outlet 3 arranged opposite to each other. The first gear 5 and the second gear 6 of the air guiding assembly are both set within the air guiding cavity 9, located between the air inlet 2 and the air outlet 3. When the first gear 5 and the second gear 6 rotate, the gas in the air guiding cavity 9 flows from the air inlet 2 to the air outlet 3. By setting a handle 7 on the housing 1, the handle 7 passes through the housing 1 and is connected to the first gear 5 for transmission. By rotating the handle 7, the first gear 5 can be rotated, thereby driving the second gear 6 to rotate synchronously, creating a pressure difference between the two sides of the first gear 5 and the second gear 6, and under the action of the pressure difference, an airflow is formed between the air inlet 2 and the air outlet 3 of the air guiding cavity 9. Furthermore, by installing an air duct 4 on the housing 1, with its outlet connected to the air inlet 2 of the air duct cavity 9, when dust removal of the optical module is required, the inlet of the air duct 4 can be aligned with the cavity of the optical module, and the handle can be turned to draw air into the cavity of the optical module through the inlet of the air duct 4. This generates a turbulent airflow within the cavity of the optical module, carrying away the dust inside. This optical module dust removal equipment is simple to operate, achieving dust removal through airflow without the need to wipe the optical module, thus avoiding damage to the optical module. Moreover, because the airflow direction within the optical module cavity is from the inside out, compared to existing technologies, it avoids further blowing dust into the optical module and causing secondary pollution.
[0039] Furthermore, the optical module dust removal equipment in this embodiment can be operated manually without carrying a power supply, allowing for dust removal operations in areas without power, thus expanding the application scenarios of the optical module dust removal equipment.
[0040] In some embodiments, the number of teeth of the first gear 5 is greater than the number of teeth of the second gear 6.
[0041] For example, the first gear 5 has 25 teeth and the second gear 6 has 9 teeth.
[0042] In some embodiments, the ratio of the number of teeth of the first gear 5 to the number of teeth of the second gear 6 is n, where 2≤n≤4.
[0043] For example, the gear ratio n between the first gear 5 and the second gear 6 can be 2, 3 or 4, etc.
[0044] When the handle 7 is directly connected to the first gear 5, one rotation of the handle 7 will cause the first gear 5 to rotate one rotation. Because the first gear 5 has a large number of teeth, more teeth can mesh between the first gear 5 and the second gear 6, increasing the intensity of the airflow generated when the first gear 5 and the second gear 6 rotate, thereby improving the cleaning effect on dust inside the optical module cavity. Furthermore, the above configuration can reduce the size of the second gear 6 while ensuring the intensity of the airflow generated by the first gear 5 and the second gear 6, which is beneficial to reducing the overall size and production cost of the optical module dust removal equipment.
[0045] In some embodiments, the module of both the first gear 5 and the second gear 6 is a, where 0.4mm ≤ a ≤ 0.6mm.
[0046] For example, the value of 'a' can be 0.4mm, 0.5mm, or 0.6mm, etc.
[0047] The module of a gear will affect the tooth height and tooth pitch of the gear. After verification, the inventors found that setting the module a of the first gear 5 and the second gear 6 to the above range can make the tooth height and tooth pitch of the first gear 5 and the second gear 6 within a reasonable range, so that the first gear 5 and the second gear 6 mesh more tightly, and the pressure difference generated when the first gear 5 and the second gear 6 rotate can better drive the gas flow in the air guide chamber 9.
[0048] In some embodiments, the inlet of the air duct 4 is adapted to the interface of the optical module so that the inlet of the air duct 4 can be inserted into the interface of the optical module.
[0049] For example, the interface of the optical module can be an LC interface or an SC interface.
[0050] The inlet of the air duct 4 is compatible with the interface of the optical module, meaning that the inlet of the air duct 4 can be inserted into the interface of the optical module.
[0051] With the above settings, the inlet of the air duct 4 can be easily inserted into the cavity of the optical module to suck out the dust inside the cavity of the optical module through the inlet of the air duct 4.
[0052] In some embodiments, the air duct 4 is detachably mounted on the housing 1.
[0053] For example, a first guide pipe is provided at the air inlet of the air guide cavity 9 on the housing 1, and the air guide pipe 4 is sleeved on the outside of the first guide pipe and then fixed on the first guide pipe.
[0054] For example, in practical applications, multiple air ducts 4 can be prepared, and the inlets of the multiple air ducts 4 can be adapted to the interfaces of multiple different optical modules. When it is necessary to clean the dust of a specific type of optical module, the corresponding type of air duct 4 can be directly replaced.
[0055] The above settings facilitate the replacement of the air duct 4, enabling the optical module dust removal equipment to be applicable to the dust removal of different models of optical modules.
[0056] In some embodiments, such as Figure 1 and Figure 2 As shown, the optical module dust removal equipment also includes a dust filter bag 8, which is installed on the housing 1 and fitted onto the air outlet 3 of the air guide cavity 9 to collect dust in the gas discharged from the air outlet 3.
[0057] For example, the dust filter bag 8 can be attached to the housing 1 by rope.
[0058] The above settings can collect dust from the gas discharged from the air outlet 3, preventing dust from affecting the on-site construction environment and causing secondary pollution to the optical module.
[0059] In some embodiments, the material of the dust filter bag 8 includes a microporous filter membrane material with a pore size of less than 1 μm.
[0060] For example, the pore size of the microporous filter membrane material can be set between 0.1 μm and 1 μm, which can ensure the filtration of dust and avoid the microporous filter membrane material from being easily clogged due to the pore size being too small.
[0061] Microporous filter membrane materials have the characteristics of relatively uniform pore size, high porosity and low resistance. Through the above settings, the dust filter bag 8 can ensure the collection effect of dust in the gas discharged from the outlet 3.
[0062] In some embodiments, the dust filter bag 8 is provided with a transparent viewing window.
[0063] For example, the dust filter bag 8 may be provided with an observation window made of transparent plastic.
[0064] The above setup allows for easy monitoring of the amount of dust in the dust filter bag 8, enabling timely replacement of the dust filter bag 8 when excessive dust accumulates, thus ensuring the effective collection of dust from the gas discharged from the outlet 3.
[0065] In some embodiments, the dust filter bag 8 is detachably mounted on the housing 1.
[0066] For example, a second inlet pipe is provided at the air outlet 3 of the air guide cavity 9 on the housing 1, and the dust filter bag 8 is tied to the second inlet pipe by an elastic band.
[0067] The above settings facilitate the disassembly and assembly of the dust filter bag 8, making it easy to replace the dust filter bag 8.
[0068] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
