A data supply device based on data storage

Abstract

The invention relates to the technical field of data supply devices, and discloses a data supply device based on data storage, including a storage device body and a plug-in block. A protective mechanism is arranged inside the plug-in block. By aligning the plug-in block with a USB interface of a reading device, a raised portion of the reading device pushes a vertical slide to slide inside the plug-in block. The vertical slide drives a wiping block to move in the direction of the storage device body. The vertical slide is used to slide inside the plug-in block to wipe a metal sheet on the top surface of the plug-in block. The vertical slide drives a horizontal push rod to drive a sliding plate 1 to slide inside a shell. A negative pressure is formed in a closed space formed by the left side wall of the sliding plate 1 and the shell. Dust on the surface of the position where the wiping block contacts the metal sheet in the plug-in block is sucked into the exhaust hole together with the gas and then enters the shell to reach the left side of the sliding plate 1. When the wiping block wipes the surface of the inlet and outlet sheets, dust on the metal sheet and inside the plug-in block is sucked into the shell, thereby reducing dust on the metal sheet.

If this dust is not cleaned for a long time, it will form muddy scale, which affects the fitting contact between the metal sheets of the storage device and the reading device, thereby affecting the data transmission. The prior art discloses a USB flash drive (CN201810663773.6), including a shell, a memory card is arranged in the shell, and the memory card is connected to the connection end. An opening is arranged on the shell, a slot body is arranged on the shell, and a sliding button is arranged in the slot body. The connection end of the sliding button is fixedly connected and can drive the connection end to slide out of the opening. A cover is hinged on the shell, and a first magnet is arranged on the cover.

A cover is hinged on the outer shell, and the cover and the outer shell are adsorbed by magnets to achieve effective dust prevention and protect the connection end. The dust prevention effect is mainly improved by blocking the access port of the storage device. However, there is no way to deal with the dust adhering to the metal sheet and the dust inside the device. Therefore, there is an urgent need to propose a data supply device based on data storage.

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the present invention provides a data supply device based on data storage, which has the following beneficial effects:

[0018] 1. The data supply device based on data storage, by aligning the plug-in block with the USB interface of the reading device, the raised part of the reading device pushes the vertical slide to slide inside the plug-in block, the vertical slide drives the wiping block to move in the direction where the storage device body is located, the top surface of the wiping block fits with the metal sheet on the top surface of the plug-in block, the vertical slide is used to slide in the plug-in block to wipe the metal sheet on the top surface of the plug-in block, the surface of the metal sheet in the plug-in block is cleaned before the metal sheet of the reading device contacts the metal sheet in the plug-in block, and the cleanliness of the position where the metal sheet in the plug-in block and the metal sheet of the reading device fit is improved, the vertical slide pushes the horizontal push rod to drive the sliding plate 1 to slide in the shell, the left side wall of the sliding plate 1 forms a closed space with the shell to form a negative pressure, the dust on the surface of the position where the wiping block contacts the metal sheet in the plug-in block is sucked into the exhaust hole together with the gas, and then enters the shell to reach the left side of the sliding plate 1, when the wiping block wipes the surface of the inlet and outlet sheets, the metal sheet and the dust inside the plug-in block are sucked into the shell, and the dust on the metal sheet is reduced.

[0019] 2. The data supply device based on data storage is provided with a wiping block and a vertical slide. When the plug-in block is not connected to the reading device, the wiping block and the vertical slide close the opening of the plug-in block to reduce the entry of dust, and further reduce the pollution of dust to the metal sheet in the plug-in block.

[0020] 3. The data supply device based on data storage, by providing a wiping block and a vertical slide, blocks the opening position of the plug-in block when the plug-in block is not connected to the reading device, and seals the metal sheet in the plug-in block, thereby reducing the probability of the storage device body and the plug-in block being damaged by hard objects in a container or on the body, thereby better protecting the metal sheet.

[0021] 4. The data supply device based on data storage pushes the vertical slide plate to slide into the inside of the plug-in block through the raised position of the device, and the horizontal push rod pushes the sliding plate one to push the gas between the sliding plate one and the partition plate to the right side of the partition plate. The air pressure on the right side of the partition plate increases, and the alcohol stored on the right side of the partition plate is pressed into the liquid pipe through the liquid extraction hole. The alcohol reaches the liquid inlet hole through the horizontal tube one and then enters the liquid injection hole on the top surface of the connecting plate. The alcohol is sprayed onto the metal sheet on the top surface of the plug-in block through the liquid injection hole, thereby further cleaning the stains on the metal sheet.

[0022] 5. The data supply device based on data storage sprays alcohol onto the surface of the metal sheet, and the alcohol vaporizes at room temperature. The process of alcohol vaporization is endothermic. When the alcohol on the metal sheet vaporizes, the temperature of the metal sheet and the plug-in block inside the plug-in block decreases. When the plug-in block is connected to a reading device to transmit data at a large flow rate, a low temperature environment is maintained for a period of time, which can effectively suppress the heat generation of the plug-in block and the metal sheet and provide a stable output environment for data transmission.

[0023] 6. The data supply device based on data storage sets the same spring between the left side wall of the sliding plate 1 and the left side wall inside the shell. The movement of the sliding plate 1 presses the gas between the sliding plate 1 and the partition plate into the liquid intake hole through the constant pressure hole. After the data transmission is completed, in the process of pulling out the plug-in block, the sliding plate 1 moves toward the opening direction of the plug-in block, and the gas inside the plug-in block passes through the one-way valve on the right side wall of the shell into the shell to balance the volume of the liquid loss, so that the gas in the plug-in block flows. After a large flow of data is transmitted, the heated parts lose heat better in the environment of the flowing gas, which is more conducive to cooling the plug-in block afterwards.

[0024] 7. The data supply device based on data storage, when the sliding plate 1 moves toward the opening direction of the plug-in block, the left side wall of the sliding plate 1 discharges the gas in the shell out of the shell through the one-way valve on the left side wall of the shell, so that the gas in the plug-in block flows again, and the air intake effect of the one-way valve on the right side wall of the shell makes the shell perform breathing-like gas flow, which better cools down the heated parts inside the plug-in block.

[0025] 8. The data supply device based on data storage, when the horizontal push rod moves into the plug-in block, the bottom surface of the vertical slide pushes the sliding block downward to drive the lower sliding block on the connecting rod to slide out of the sliding groove. The left wall of the rubber block fits with the surface of the reading device. The friction between the left wall of the rubber block and the reading device is used to provide an upward supporting force for the entire device. In addition to the supporting effect formed by the connection between the plug-in block and the device body, an additional upward supporting force is provided to overcome the gravity of the entire device, thereby avoiding the phenomenon of loose connection between the plug-in block and the reading device caused by long-term use.

[0026] 9. The data supply device based on data storage, after the plug-in block is connected to the reading device, the lower slider slides out of the slide groove and extends to the outside of the storage device body, and the contact surface between the storage device body and the outside is increased by the lower slider. The temperature of the outside is lower than the temperature inside the plug-in block. The heat generated inside the plug-in block is dissipated into the air through the lower slider, so as to better dissipate the heat inside the plug-in block.

[0027] 10. The data supply device based on data storage, through the setting of the protection mechanism of the present invention, uses a wiping block and a vertical slide to cover the opening of the plug-in block before the plug-in block is connected to the reading device. When the plug-in block is connected to the device, the rubber block provides support for the entire device and increases the heat dissipation area. After the transmission is completed, the gas inside the plug-in block flows in a breathing manner, thereby realizing all-round protection of the device in the whole process.

The top surface of the wiping block 12 fits with the metal sheet on the top surface of the plug-in block 11. The vertical slide 13 is used to slide inside the plug-in block 11 to wipe the metal sheet on the top surface of the plug-in block 11. Before the metal sheet of the reading device contacts the metal sheet in the plug-in block 11, the surface of the metal sheet in the plug-in block 11 is cleaned, thereby improving the cleanliness of the fitting position of the metal sheet in the plug-in block 11 and the metal sheet of the reading device. The vertical slide plate 13 pushes the horizontal push rod 19 to drive the sliding plate 21 to slide in the shell 20. The left side wall of the sliding plate 21 and the shell 20 form a closed space with negative pressure. The dust on the surface of the position where the wiping block 12 contacts the metal sheet in the plug-in block 11 is sucked into the exhaust hole 15 together with the gas and then enters the shell 20 to reach the left side of the sliding plate 21. When the wiping block 12 wipes the surface of the inlet and outlet sheets, the dust on the metal sheet and the inside of the plug-in block 11 is sucked into the shell 20 to reduce the dust on the metal sheet.

[0036] By providing the wiping block 12 and the vertical slide 13 , when the plug-in block 11 is not connected to the reading device, the wiping block 12 and the vertical slide 13 close the opening of the plug-in block 11 to reduce the entry of dust, and further reduce the dust pollution to the metal sheet in the plug-in block 11 .

[0038] The vertical slide 13 is adapted to the opening of the plug-in block 11, the wiping block 12 is fixedly connected to the top surface of the vertical slide 13, and the wiping block 12 is fitted with the metal sheet on the top surface of the plug-in block 11, the transverse cross-section of the exhaust hole 15 is L-shaped, the upper end opening of the exhaust hole 15 is located below the wiping block 12, and the right end opening of the exhaust hole 15 is located in the shell 20. The protective mechanism also includes a liquid inlet hole 14, a vertical pipe 16, a connecting plate 17, a liquid injection hole 18, a partition plate 22, a liquid suction pipe 24 and a transverse pipe 26. The partition plate 22 is fixedly connected to the inner wall of the shell 20, the transverse pipe 26 passes through the partition plate 22 and the transverse pipe 26 is slidably connected to the partition plate 22, the liquid suction pipe 24 is fixedly connected to the shell 20 and the transverse pipe 26 is slidably connected to the liquid suction pipe 24, and the left end surface of the horizontal push rod 19 A liquid inlet hole 14 is also provided, a transverse tube 26 is also fixedly connected to a sliding plate 21 and the transverse tube 26 is communicated with the liquid inlet hole 14, a vertical tube 16 is fixedly connected to a horizontal push rod 19, a connecting plate 17 is fixedly connected to the vertical tube 16, a liquid injection hole 18 is provided on the top surface of the connecting plate 17, the connecting plate 17 is a plate with a rectangular horizontal cross section, the liquid injection hole 18 is communicated with the liquid inlet hole 14 through the vertical tube 16, a transverse tube 26 penetrates the sliding plate 21 and a left end surface of the transverse tube 26 is fixedly connected to a right end surface of the horizontal push rod 19, a left end opening of the transverse tube 26 is located directly to the right of the liquid inlet hole 14, a right end opening of the exhaust hole 15 is located on the side wall of the horizontal push rod 19 and a right end opening of the exhaust hole 15 is located between the left side wall of the sliding plate 21 and the left side wall inside the shell 20. The protective mechanism is also It includes a constant pressure hole 23, a liquid collection hole 25 and a one-way valve 27. The constant pressure hole 23 is provided on the partition plate 22, and the liquid collection hole 25 is provided on the side wall of the liquid suction pipe 24. The one-way valve 27 is fixedly connected to the right side wall of the shell 20. The liquid suction pipe 24 is a circular tube with an L-shaped transverse cross-section. The liquid suction pipe 24 is fixedly connected to the inner bottom surface of the shell 20. The circumferential surface of the liquid suction pipe 24 is provided with a liquid collection hole 25. The liquid collection hole 25 is located between the right side wall of the partition plate 22 and the inner side wall of the shell 20. There are three one-way valves 27. The left side wall of the shell 20 is symmetrically provided with the same one-way valve 27 in the same way as the right side wall of the shell 20. Another identical one-way valve 27 is provided at the right end opening of the exhaust hole 15. The one-way valves 27 on the left side wall of the shell 20 and the right side wall of the shell 20 can only discharge liquid to the outside of the shell 20. The one-way valve 27 on the right side wall of the shell 20 ensures that air can only enter the shell 20, and the one-way valve 27 on the exhaust hole 15 ensures that gas can only enter the shell 20. The vertical slide 13 is pushed to slide into the inside of the plug-in block 11 by the raised position of the reading device, and the horizontal push rod 19 pushes the sliding plate 21 to push the gas between the sliding plate 21 and the partition plate 22 to the right side of the partition plate 22. The air pressure on the right side of the partition plate 22 increases, and the alcohol stored on the right side of the partition plate 22 is pressed into the suction tube 24 through the liquid extraction hole 25. The alcohol reaches the liquid inlet hole 14 through the horizontal tube 26 and then enters the liquid injection hole 18 on the top surface of the connecting plate 17. The alcohol is sprayed onto the metal sheet on the top surface of the plug-in block 11 through the liquid injection hole 18, thereby further cleaning the stains on the metal sheet.

[0039] By spraying alcohol on the surface of the metal sheet, the alcohol can be vaporized at room temperature. The process of alcohol vaporization is endothermic. When the alcohol on the metal sheet vaporizes, the temperature of the metal sheet inside the plug-in block 11 decreases. When the plug-in block 11 is connected to a reading device to transmit data at a high flow rate, a low temperature environment is maintained for a period of time, which can effectively suppress the heat generation of the plug-in block 11 and the metal sheet, thereby providing a stable output environment for transmitting data.

[0040] The same spring 31 is arranged between the left side wall of the sliding plate 21 and the left side wall inside the shell 20. The movement of the sliding plate 21 presses the gas between the sliding plate 21 and the partition plate 22 into the liquid intake hole 25 through the constant pressure hole 23. After the data transmission is completed, in the process of pulling out the plug block 11, the sliding plate 21 moves toward the opening direction of the plug block 11, and the gas inside the plug block 11 passes through the one-way valve 27 on the right side wall of the shell 20 to enter the shell 20 to balance the volume of the liquid loss, so that the gas in the plug block 11 flows. After a large flow of data is transmitted, the heated parts lose heat better in the environment of the flowing gas, which is more conducive to cooling the plug block 11 afterwards.

[0041] During the movement of the sliding plate 21 toward the opening direction of the plug-in block 11, the left side wall of the sliding plate 21 discharges the gas in the shell 20 out of the shell 20 through the one-way valve 27 on the left side wall of the shell 20, so that the gas in the plug-in block 11 flows again. Combined with the air intake effect of the one-way valve 27 on the right side wall of the shell 20, the shell 20 performs a breathing-like gas flow, which better cools down the heated parts inside the plug-in block 11.

[0042] The protection mechanism also includes a sliding block 28, a connecting rod 32, a rubber block 33 and a lower sliding block 34. The sliding block 28 is slidably connected to the plug-in block 11, the connecting rod 32 is fixedly connected to the sliding block 28, the rubber block 33 is fixedly connected to the lower sliding block 34, and the lower sliding block 34 is fixedly connected to the connecting rod 32. The protection mechanism also includes a sliding block 29, a sliding groove 30 and a spring 31. The bottom surface of the storage device body 10 is provided with a sliding groove 30, the sliding block 29 is slidably connected to the sliding groove 30, and the sliding block 29 is fixedly connected to the sliding block 28, one end of the spring 31 is fixedly connected to the sliding block 29, and the other end of the spring 31 is fixedly connected to the storage device body 10. The transverse section of the sliding groove 30 is an inverted F shape, the sliding block 28 is slidably connected to the sliding groove 30, the rubber block 33 and the lower sliding block 34 are both located in the sliding groove 30, and the sliding block The transverse cross-section of the rubber block 33 is a trapezoid and the inclined surface of the sliding block 28 is to the left. When the left side wall of the rubber block 33 is flush with the left side wall of the storage device body 10, the top surface of the sliding block 28 is flush with the inner bottom surface of the plug-in block 11. During the movement of the horizontal push rod 19 into the plug-in block 11, the bottom surface of the vertical slide plate 13 pushes the sliding block 28 downward to drive the lower slider 34 on the connecting rod 32 to slide out of the slide groove 30. The left side wall of the rubber block 33 fits the surface of the reading device. The friction between the left side wall of the rubber block 33 and the reading device is used to provide an upward supporting force for the entire device. In addition to the supporting effect formed by the connection between the plug-in block 11 and the device body, an additional upward supporting force is provided to overcome the gravity of the entire device, thereby avoiding the phenomenon of loose connection between the plug-in block 11 and the reading device caused by long-term use.

[0043] After the plug-in block 11 is connected to the reading device, the lower slider 34 slides out of the slide groove 30 and extends to the outside of the storage device body 10. The lower slider 34 increases the contact surface between the storage device body 10 and the outside world. The temperature of the outside world is lower than the temperature inside the plug-in block 11. The heat generated inside the plug-in block 11 is dissipated into the air through the lower slider 34, which better dissipates the heat inside the plug-in block 11.

[0044] By setting the protective mechanism of the present invention, before the plug-in block 11 is connected to the reading device, the wiping block 12 and the vertical slide 13 are used to cover the opening of the plug-in block 11. When the plug-in block 11 is connected to the device, the rubber block 33 provides support for the entire device and increases the heat dissipation area. After the transmission is completed, the gas inside the plug-in block 11 flows in a breathing manner, thereby realizing all-round protection of the device in the whole process.

Alcohol passes through the horizontal tube 26 to reach the liquid inlet hole 14 and then enters the liquid injection hole 18 on the top surface of the connecting plate 17. Alcohol is sprayed onto the metal sheet on the top surface of the plug-in block 11 through the liquid injection hole 18. During the movement of the horizontal push rod 19 into the plug-in block 11, the bottom surface of the vertical slide plate 13 pushes the sliding block 28 downward to drive the lower sliding block 34 on the connecting rod 32 to slide out of the slide groove 30. The left side wall of the rubber block 33 fits the surface of the reading device. After the data transmission is completed, during the process of the plug-in block 11, the sliding plate 21 moves toward the opening direction of the plug-in block 11. The gas inside the plug-in block 11 enters the shell 20 through the one-way valve 27 on the right side wall of the shell 20 to balance the volume of the liquid loss, so that the gas in the plug-in block 11 flows, and the left side wall of the sliding plate 21 discharges the gas in the shell 20 through the one-way valve 27 on the left side wall of the shell 20 to the outside of the shell 20. The wiping block 12 and the vertical slide plate 13 block the opening position of the plug-in block 11 again.
