Description

Technical Field

[0001] This utility model relates to the field of printer heat dissipation technology, and more specifically to a printer heat dissipation accessory. Background Technology

[0002] A printer is one of the output devices of a computer, used to print the results of computer processing onto relevant media.

[0003] For example, patent CN211591901U discloses a printer heat dissipation accessory, including a printer body. Four pads are fixedly installed on the bottom of the printer body, an operation panel is fixedly installed on the front of the printer body, a cooling box is fixedly installed on the left inner wall of the printer body, and a sealing seat is fixedly installed on the top of the printer body. This printer heat dissipation accessory absorbs heat emitted from the printer body by installing a cooling box filled with coolant. A protective frame with ventilation holes is installed on the protective frame, and a cooling fan is installed on the protective frame. When the cooling fan rotates, it quickly dissipates heat from inside the printer body through the heat conduction and dissipation holes. Ultimately, by absorbing and rapidly dissipating heat, a good heat dissipation effect is achieved.

[0004] In actual operation, the printer's cooling vents are directly exposed, and heat is dissipated by the internal cooling fan. However, because printers are often left outside for extended periods due to work requirements and are not easy to store, a lot of dust accumulates in the cooling vents, hindering heat dissipation. Furthermore, the printer only uses the cooling fan when in use, and after a long period of time, the dust will stick to the cooling vents. Simply blowing air cannot clean the accumulated dust, which in turn causes the dust to continue to accumulate, reducing the efficiency of heat dissipation.

[0005] It is evident that the aforementioned problems with existing technologies urgently need to be addressed. Utility Model Content

[0006] In view of the above-mentioned problems in the existing technology, one aspect of the purpose of this utility model is to provide a printer heat dissipation accessory to solve the problems that printers are placed outdoors for a long time due to their working nature, resulting in a lot of dust accumulating in the heat dissipation slots. Moreover, the accumulated dust cannot be cleaned when the printer is not in use, causing the dust to stick to the heat dissipation slots, making it difficult to clean, and reducing the efficiency of heat dissipation.

[0007] To achieve the above objectives, this utility model provides a printer heat dissipation accessory, including a heat dissipation component disposed on the outer wall of the printer. The heat dissipation component has linearly arrayed heat dissipation slots inside, and a heat dissipation fan is disposed at the end of each heat dissipation slot away from the outlet. An auxiliary accessory assembly is snapped onto the outer wall of the heat dissipation component. The auxiliary accessory assembly includes snap-fit ​​plates arranged in a linear array, each snap-fit ​​plate being driven to fit and snap into the interior of each heat dissipation slot. The outer wall of the auxiliary accessory assembly has linearly arrayed heat dissipation slots communicating with the heat dissipation slots. A cleaning mechanism is disposed inside each heat dissipation slot, and a limiting mechanism is provided at the opposite ends of the cleaning mechanism connected to the heat dissipation slot to drive the cleaning mechanism to maintain unidirectional rotation.

[0008] Preferably, the heat dissipation component includes a heat dissipation plate disposed on the outer wall of the printer, and the auxiliary accessory component includes an auxiliary heat dissipation plate. Each of the snap-fit ​​plates is arranged in a linear array on the outer wall of the auxiliary heat dissipation plate, and the tilt angle of the snap-fit ​​plates is consistent with that of the heat dissipation vent.

[0009] Preferably, each of the snap-fit ​​plates has a hook at the end away from the auxiliary heat sink to snap into the end of the heat sink.

[0010] Preferably, the cleaning mechanism specifically includes a rotating shaft disposed inside the heat dissipation groove, and the outer wall of the rotating shaft is provided with elastic scrapers arranged in a circumferential array, the elastic scrapers being tangent to the heat dissipation groove.

[0011] Preferably, the limiting mechanism specifically includes ratchet wheels disposed at opposite ends of the rotating shaft, and the opposite ends of the heat dissipation groove are provided with retaining plates that can maintain axial rotation to engage inside the ratchet wheels, so as to limit the rotating shaft to maintain unidirectional rotation.

[0012] Beneficial effects:

[0013] Compared with the prior art, the printer heat dissipation accessory provided by this utility model has the following beneficial effects:

[0014] 1. By installing a rotating shaft and a flexible scraper inside the heat dissipation slot, the heat dissipation slot can be blocked. When the printer is not cooling down, the flexible scraper is not blown by the cooling fan, which can prevent external dust from entering the heat dissipation slot.

[0015] 2. The cooling fan blows air to dissipate heat, causing the elastic scraper to rotate axially. This rotation blows out internal dust, thus contributing to heat dissipation. Furthermore, the elastic scraper remains tangential to the heat dissipation groove, allowing for scraping and cleaning of the groove's inner wall to prevent dust from sticking and accumulating, which would reduce heat dissipation efficiency.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-4 As shown, a printer heat dissipation accessory includes a heat dissipation component 1, which is disposed on the outer wall of the printer. The heat dissipation component 1 has heat dissipation slots 102 arranged in a linear array inside. A heat dissipation fan is disposed at the end of the heat dissipation slots 102 away from the outlet. An auxiliary accessory component 2 is snapped onto the outer wall of the heat dissipation component 1. The auxiliary accessory component 2 includes snap-fit ​​plates 202 arranged in a linear array. Each snap-fit ​​plate 202 is driven to fit and snap into the interior of each heat dissipation slot 102. The outer wall of the auxiliary accessory component 2 has heat dissipation grooves 204 arranged in a linear array to maintain communication with the heat dissipation slots 102. A cleaning mechanism is disposed inside each heat dissipation groove 204. The cleaning mechanism is connected to the heat dissipation groove 204 at opposite ends and a limiting mechanism is provided to drive the cleaning mechanism to maintain unidirectional rotation.

[0025] The main purpose of this printer heat dissipation accessory is to block the heat dissipation slot 204 by setting a rotating shaft 205 and an elastic scraper 206 inside the heat dissipation slot 204. When the printer is not cooling, the elastic scraper 206 is not blown by the cooling fan, which can prevent external dust from entering the heat dissipation slot 102. When the cooling fan blows air, the elastic scraper 206 is subjected to force and rotates axially, thereby blowing out the internal dust with the rotation of the elastic scraper 206, which also contributes to heat dissipation. Furthermore, by keeping the elastic scraper 206 tangential to the heat dissipation slot 204, it can perform scraping and cleaning work on the inner wall of the heat dissipation slot 204, preventing dust from sticking and accumulating, thus reducing the heat dissipation efficiency.

[0026] In the technical solution provided by this utility model, by Figure 1 , Figure 2 , Figure 3 and Figure 4 It is known that the heat dissipation component 1 includes a heat dissipation plate 101, which is disposed on the outer wall of the printer and is an original device of the printer for heat dissipation. The auxiliary accessory component 2 includes an auxiliary heat dissipation plate 201, and each snap-fit ​​plate 202 is arranged in a linear array on the outer wall of the auxiliary heat dissipation plate 201. The tilt angle of the snap-fit ​​plate 202 is consistent with that of the heat dissipation duct 102, so that it can fit tightly against the outer wall of the heat dissipation duct 102, so that the auxiliary heat dissipation plate 201 can be snapped onto the outer wall of the heat dissipation plate 101, and each heat dissipation duct 204 and the heat dissipation duct 102 are corresponding and connected. When the internal heat dissipation fan blows air to dissipate heat, hot air can be discharged to the outside.

[0027] Furthermore, each snap-fit ​​plate 202 has a snap-fit ​​hook 203 at the end away from the auxiliary heat dissipation plate 201 to snap-fit ​​the end of the heat dissipation plate 101, so that the auxiliary heat dissipation plate 201 can be fixed to the outer wall of the heat dissipation plate 101 to perform auxiliary heat dissipation work.

[0028] Furthermore, the cleaning mechanism specifically includes a rotating shaft 205 installed inside the heat dissipation slot 204, and the outer wall of the rotating shaft 205 is provided with elastic scrapers 206 arranged in a circumferential array. The cooling fan blows air to dissipate heat, causing the bent elastic scrapers 206 to be driven by the airflow to rotate the rotating shaft 205 axially, which can dissipate heat and also discharge the dust inside the heat dissipation slot 102 outward in sequence, preventing dust accumulation from blocking the air outlet of the heat dissipation slot 102. The elastic scrapers 206 are also tangent to the heat dissipation slot 204, so that the elastic scrapers 206 can scrape and clean the inner wall of the heat dissipation slot 204, preventing dust from accumulating and sticking.

[0029] Furthermore, the limiting mechanism specifically includes ratchet 207s disposed at opposite ends of the rotating shaft 205, and the opposite ends of the heat dissipation groove 204 are provided with locking plates 208 that can maintain axial rotation to engage inside the ratchet 207 to abut against the ratchet 207, thereby limiting the rotating shaft 205 to maintain unidirectional rotation.

[0030] Working principle: First, insert the snap-fit ​​plate 202 into the heat dissipation duct 102, and then hook the snap-fit ​​hook 203 onto the end of the heat dissipation duct 102 so that the auxiliary heat dissipation plate 201 can be fixed to the outer wall of the heat dissipation plate 101 to perform auxiliary heat dissipation work.

[0031] When the printer is not working, the cooling fan does not blow air. At this time, the rotating shaft 205 and the elastic scraper 206 block the heat dissipation groove 204 to prevent dust from falling into the heat dissipation groove 102 and causing blockage inside the heat dissipation groove 102, thus reducing the heat dissipation efficiency.

[0032] When the printer is working, the cooling fan blows air to dissipate heat, causing the curved elastic scraper 206 to be subjected to air force. The ratchet 207 at both ends of the rotating shaft 205 causes the rotating shaft 205 to rotate axially in one direction, which dissipates heat. It can also discharge the dust inside the cooling air duct 102 outward in sequence, preventing dust from accumulating and blocking the air outlet of the cooling air duct 102.

[0033] Furthermore, the elastic scraper 206 remains tangent to the heat sink 204, allowing the elastic scraper 206 to scrape and clean the inner wall of the heat sink 204, preventing dust from accumulating and sticking.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
