Description

Technical Field

[0001] The utility model relates to the field of electronics, and particularly to an electric soldering iron sucker. Background Art

[0002] An electric soldering iron sucker is a tool widely used in the process of electronic repair and manufacturing, mainly used for collecting the melted solder when disassembling electronic components on the pads. With the rapid development of electronic technology, the complexity and integration of electronic devices are constantly increasing, and the requirements for repair and manufacturing tools are also getting higher and higher. The electric soldering iron sucker has become an indispensable tool in the field of electronic repair and manufacturing with its characteristics of high efficiency, convenience, and precision.

[0003] The soldering iron sucker basically consists of a power supply, a control circuit, a piston-type vacuum pump, a filter, and a soldering iron suction handle, etc. The power supply provides the required electrical energy for the electric soldering iron sucker, and the control circuit is responsible for regulating and managing the output of the power supply to ensure that the electric soldering iron sucker can operate according to a predetermined mode and speed. When the power supply is started, the control circuit will drive the piston-type vacuum pump to start working. The piston reciprocates in the pump body, generating suction by changing the volume in the pump body. When the soldering point is heated by a soldering iron until the solder melts, quickly bring the soldering iron suction handle close to the soldering point and press the button on the soldering iron sucker. At this time, the suction generated by the vacuum pump will suck the melted solder into the soldering iron suction handle through the filter for filtration and collection.

[0004] However, during the process of implementing the technical solution of the present invention in the embodiments of the present application, the inventors of the present application found that the above technology has at least the following technical problems:

[0005] 1. The handle structure of the electric soldering iron sucker on the market at present is complex, the soldering iron suction efficiency is low, it is not convenient for users to disassemble and repair, and users cannot observe the storage state of the tin in the quartz tube inside the handle in real time, which in turn leads to the inability to clean the remaining tin in time, affecting the safety and stability of the equipment;

[0006] 2. When the electric soldering iron sucker is running, when the vacuum pump inside the soldering iron suction table is running, the noise reaches 60 dB, and the vibration is also relatively large. The vacuum degree can only reach about -80 kPa. Moreover, the handle part is composed of a heating core, a separately configured soldering iron suction pipe, and an outer suction nozzle. Because the separately configured soldering iron suction pipe is a secondary combination, the sealing is not tight, resulting in air leakage during use. In addition, the aperture cannot be made large. During soldering iron suction, due to air leakage and unsmooth channels, the outer suction nozzle also has a small contact surface with the heating core, resulting in low heat transfer efficiency and difficulty in melting the solder, and the soldering iron suction effect is not good. Summary of the Utility Model

[0007] By providing a solder sucker in an embodiment of the present application, the problems in the prior art that the structure of the solder suction handle is complex and the disassembly is inconvenient are solved.

[0031] Among them, the same reference numerals in the drawings all refer to the same components.

[0032] Embodiment 1

[0033] As Figures 1-5As shown in the figure, the present utility model provides an electric desoldering pump, which includes a desoldering station 4, a desoldering handle 6 and a switch 7. The desoldering handle 6 is provided with an upper cover 1 and a base 2. One side of the upper cover 1 is provided with a first upper cover 101, and the other side of the upper cover 1 is provided with a second upper cover 102. The top center of the first upper cover 101 is provided with a rear card slot 103, and the upper part of the top surface of the second upper cover 102 is provided with a front card slot 104. The bottom surface of the upper cover 1 is provided with two groups of third mounting parts 105;

[0034] One side of the base 2 is provided with a first base 201. The inner surface of the first base 201 is provided with two groups of second mounting parts 202 and a first mounting part 207. One side of the first mounting part 207 is provided with a fixing part 203, and one side of the fixing part 203 is provided with a rear hook 204. The other side of the base 2 is provided with a second base 205. The upper part of the inner surface of the second base 205 is provided with a front hook 206, and the front hook 206 fits inside the front card slot 104.

[0035] Specifically, as Figure 1 、 Figure 2 and Figure 3 shown, the front hook 206 provided on the second base 205 is used to be inserted into the front card slot 104 of the second upper cover 102. The bottom of the second upper cover 102 provided with the front card slot 104 fits with the second base 205, so that the second upper cover 102 is fixed on the second base 205. The rear card slot 103 on the top surface of the first upper cover 101 is used to cooperate with the rear hook 204 for fixing. First, align the front card slot 104 of the second upper cover 102 with the front hook 206 and insert it. After that, when one side of the second upper cover 102 is fitted with the second base 205, press the upper cover 1 and the first upper cover 101 downward. The inner wall of the first upper cover 101 will press the front end of the rear hook 204, causing the rear hook 204 to deform. Until the lower end of the first upper cover 101 fits to the first base, the rear card slot 103 will move to the front end of the rear hook 204, and the rear hook 204 will return to the static state, and the front end will pass through the rear card slot 103, and cooperate with the front card slot 104 and the front hook 206 to snap-fix the upper cover 1 on the second base 205 and the first base.

[0036] The two groups of second mounting parts 202 and the first mounting part 207 are arranged in parallel. The second mounting parts 202 and the first mounting part 207 are welded to one side of the inner surface of the base 2. The bottom of the base 2 is provided with four groups of grooves 208, and the sizes of the four groups of grooves 208 are the same.

[0037] Specifically, as Figure 2 and Figure 3As shown, two sets of second mounting members 202 are used to mount the quartz tube 5, the first mounting member 207 is used to mount the fixing member 203, the fixing member 203 is used to mount the rear catch 204, and the rear catch 204 is used to catch the rear slot 103 to fix the first upper cover 101 on the first base 201. The size of the rear slot 103 is larger than the size of the front end of the rear catch 204. The groove 208 can fit naturally with the user's hand, reducing the hand fatigue of the user during long-term operation.

[0038] The front catch 206 is welded to one side of the second base 205. The second upper cover 102 is fixedly connected to the second base 205 through the front catch 206. The front catch 206 and the front slot 104 have the same size and corresponding positions. The first mounting member 207 is welded to the inner surface of the first base 201. The fixing member 203 and the first mounting member 207 are fixedly connected. The rear catch 204 is arranged at the upper part of one side surface of the fixing member 203. The rear catch 204 is made of plastic. The front end of the rear catch 204 passes through the rear slot 103 and inserts into the outer surface of the first upper cover 101.

[0039] One side surface of the upper cover 1 is provided with a window frame 3. One side of the window frame 3 is provided with an observation window 301. The inner side surface of the window frame 3 is provided with bolts 302.

[0040] The window frame 3 is installed on the outer side surface of the observation window 301. The bolt 302 is a cross-hole bolt. The observation window 301 is threadedly connected to the upper cover 1 through the bolt 302.

[0041] Specifically, as Figure 2 and Figure 3 shown, the window frame 3 is used to mount the observation window 301. Both the window frame 3 and the upper cover 1 are provided with screw holes and are fixed to the inner surface of the upper cover 1 through the bolts 302. The user can directly observe the inside of the device through the observation window 301, and can also remove the bolts 302 to disassemble the window frame 3 to wipe and clean the inner surface of the observation window 301.

[0042] The inner side surface of the soldering iron stand 4 is provided with a filter 401, an air storage tank 402, a vacuum pump 403 and a solenoid valve 404. The inner bottom surface of the soldering iron stand 4 is provided with a controller 405.

[0043] The vacuum pump 403 is specifically a double-headed diaphragm vacuum pump. The filter 401, the air storage tank 402 and the vacuum pump 403 are fixedly connected to the inner side surface of the soldering iron stand 4. The controller 405 is fixedly connected to the inner bottom surface of the soldering iron stand 4. One side of the top of the second mounting member 202 is provided with a quartz tube 5. The inner side of the quartz tube 5 is provided with a filter spring 501. The outer surface of the second base 205 is provided with a heating core 502. The inner side of the heating core 502 is provided with a solder suction channel 503. The top end of the heating core 502 is provided with a suction nozzle 504.

[0044] Specifically, the double-headed diaphragm vacuum pump generates less noise and vibration during operation. The operating noise is 52 dB, and it has a high vacuum degree with a suction force of over -90 kPa.

[0045] The quartz tube 5 is specifically a high-temperature quartz tube tin storage cylinder. The front end of the tin suction channel 503 extends into the quartz tube 5, and the rear end extends into the nozzle 504. Threaded holes are provided on the inner surface of the nozzle 504, and corresponding threaded holes are provided on the outer surface of the front end of the tin suction channel 503. The nozzle 504 and the tin suction channel 503 are threadedly connected.

[0046] Specifically, the quartz tube 5 uses a high-temperature quartz tube tin storage cylinder. Quartz material has extremely high heat resistance and can withstand the high temperature generated during the operation of the desoldering tool, ensuring its stability and reliability in a continuous high-temperature environment. The heating core 502 and the tin suction channel 503 are integrally provided, eliminating the need for an additional tin suction tube. Therefore, the tin suction aperture is large, the tin suction channel 503 is smooth, and the nozzle 504 and the tin suction channel 503 are connected by a threaded structure, in close contact with the heating core 502, with high heat transfer efficiency, and can easily melt the solder joints of large components.

[0047] The second mounting member 202 and the third mounting member 105 are attached to the outer surface of the quartz tube 5.

[0048] Specifically, as Figure 4 and Figure 5 , when the power is turned on, the current first flows to the controller to provide the necessary electrical energy for the entire system. Next, the vacuum pump 403 starts to work. The vacuum pump 403 can extract air from the gas storage tank 402 to create a negative pressure inside it, that is, a vacuum state. The gas storage tank 402, as a vacuum storage device, can quickly release the vacuum force when needed. At the same time, the heating core 502 starts to work, heating the nozzle 504 to a high temperature above 400 degrees. During the operation of the vacuum pump 403, the filter 401 plays a protective role. It can effectively prevent impurities such as slag and dust from entering the vacuum pump 403, ensuring the stable operation of the vacuum pump 403 and extending its service life. When desoldering is required, the user places the heated nozzle 504 on the solder joint to be desoldered to melt the tin. Then, the switch 7 on the handle is pressed. At this time, the solenoid valve opens, allowing the vacuum force in the gas storage tank 402 to be released. At the same time, the burst vacuum suction force generated by the vacuum pump 403 and the gas storage tank 402 quickly sucks the melted tin into the tin storage cylinder inside the handle, completing one desoldering operation. After completing one desoldering operation, the user can continue to place the nozzle 504 on the next solder joint to be desoldered and repeat the above steps to achieve continuous desoldering. This continuous operation method greatly improves work efficiency, reduces operation time, and solves the problems of large vibration noise and poor desoldering effect during the operation of the desoldering tool.

[0049] In use: First, align the front card slot 104 of the second upper cover 102 with the front catch 206 and snap it in. After one side of the second upper cover 102 is fitted to the second base 205, press the upper cover 1 and the first upper cover 101 downward. The inner wall of the first upper cover 101 will press the front end of the rear catch 204, causing the rear catch 204 to deform. Until the lower end of the first upper cover 101 is fitted to the first base 201, the rear card slot 103 will move to the front end of the rear catch 204, and the front end will pass through the rear card slot 103 and cooperate with the front card slot 104 and the front catch 206 to fix the upper cover buckle on the second base 205 and the first base 201, thus completing the installation of the upper cover 1. When it is necessary to disassemble the upper cover 1, while pressing the rear catch 204 downward, push the front end of the rear catch 204 into the device interior, and then toggle the upper cover 1 upward. Then move the front card slot 104 out of the rear catch 204 and remove the second upper cover 102 from the surface of the second base 205, thus completing the portable disassembly of the upper cover 1. The user can also check the tin storage situation in the quartz tube 5 inside the handle at any time through the observation window 301 provided on the upper cover 1, which is convenient for timely cleaning of the residual tin.

[0050] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
