Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of suction tin guns, more particularly to a kind of automatic suction tin gun. BACKGROUND

[0002] At present on the market, all brands are warmed by soldering iron. After the high temperature generated by soldering iron head and tin, the tin forms liquid. Then by vacuum suction pump, vacuum is extracted. The suction force generated will extract tin into cavity (glass tube) to store. In this process, the tin dregs in the cavity (glass tube) of the tin suction device are not easy to clean, which can easily cause the soldering tin and sundries remaining to block and hinder airflow, thereby weakening the suction force. As the suction force weakens, the washing liquid cannot reach the cavity from the suction nozzle, so it stays in the delivery pipe. After solidification, it will be more difficult to clean the residue in the delivery pipe. SUMMARY

[0003] The utility model solves the technical problems to provide a kind of automatic suction tin gun to solve the problems existing in the background art.

[0004] The utility model automatic suction tin gun is realized by the following technical scheme, including: hindering plug, cavity and filter cotton;

[0005] The hindering plug is arranged at one end of the cavity, and the filter cotton is arranged at the other end of the cavity. Small particle tin dregs are filtered through the filter cotton.

[0006] As a preferred technical scheme, the hindering plug is in tubular structure, the inside of the cavity is attached to the hindering plug but not completely closed, so that there is a gap for tin liquid to flow through. Large particle tin dregs are filtered through the gap between the inside of the cavity and the hindering plug.

[0007] As a preferred technical scheme, the other end of the cavity is connected with a vacuum suction pump, and the filter cotton is placed at the front end of the vacuum suction pump.

[0008] As a preferred technical scheme, an air suction nozzle or a conduit is arranged on the hindering plug, and the tin liquid enters from the air suction nozzle or the conduit.

[0009] As a preferred technical scheme, the material of the hindering plug is high-temperature-resistant and flame-retardant rubber.

[0010] The utility model has the beneficial effects that:

[0011] The hindering plug made of high-temperature-resistant and flame-retardant rubber replaces the hindering plug in the original cavity of the tin suction device on the market. According to the tubular structure of the cavity of the tin suction device and the attachment (but not completely closed) of the inner wall of the cavity, when the tin liquid reaches the cavity by suction force, it will be blocked by the hindering plug. Thus, the tin liquid cools down and stays in the cavity. Since the tin is not easy to firmly adhere to the rubber, the hindering plug is easy to clean.

[0012] The utility model discloses a filter cotton is installed in the tail end of cavity, can prevent the fine tin slag particle from being hindered by the obstruction plug, and the fine tin slag is hindered by the obstruction plug and falls to the rear of cavity and is inhaled into the vacuum suction pump, and the vacuum suction pump is damaged.

[0013] The tin liquid contacts the glass tube or the obstruction plug, and is not easy to adhere to the surface, when the tin liquid solidifies, the block tin slag is stored in the obstruction plug. BRIEF DESCRIPTION OF DRAWINGS

[0014] In order to more clearly illustrate the technical scheme in the embodiments of the utility model or the prior art, the following will briefly introduce the drawings needed to be used in the embodiment or the prior art description, obviously, the drawings in the following description only some embodiments of the utility model, for those skilled in the art, under the premise of not paying creative labor, other drawings can also be obtained according to these drawings.

[0020] All features disclosed in this specification, or all steps of any methods or processes disclosed, can be combined in any manner, except where features or steps are mutually exclusive.

[0021] As Figs. 1-3 The utility model discloses an automatic tin suction gun, including: obstruction plug 1, cavity 2 and filter cotton 3.

[0022] The obstruction plug 1 sets up at one end of cavity 2, and filter cotton 3 sets up at the other end of cavity 2, and the small particle tin slag is filtered through filter cotton 3.

[0023] The inside of the cavity 2 is in contact with the blocking plug 1 but not completely closed, so that there is a gap 4 for the tin liquid to flow through, and the large tin slag particles are filtered through the gap 4 between the inside of the cavity 2 and the blocking plug 1; when the tin liquid reaches the cavity through suction, it will be blocked by the blocking plug; so that the tin liquid stays in the inside of the cavity 2 (in general, the tin is not easy to firmly adhere to the rubber).

[0024] The other end of the cavity 2 is connected with a vacuum suction pump 5, and the filter cotton 3 is arranged at the front end of the vacuum suction pump 5, so that the small tin slag particles cannot be blocked by the blocking plug 1 and slide to the rear of the cavity 2 and are sucked into the vacuum suction pump 5, thereby damaging the vacuum suction pump 5.

[0025] In the embodiment, the cavity is a glass tube, and in order to facilitate the tin liquid to enter, an air suction nozzle or a pipe is arranged on the blocking plug 1 in the embodiment, and the tin liquid enters from the air suction nozzle or the pipe; when the tin liquid enters the cavity, the tin liquid contacts the glass tube or the blocking plug, and is not easy to adhere to the surface, and when the tin liquid solidifies, the block tin slag is stored in the inside of the blocking plug; the cavity can be directly opened to pour out the tin slag; after the tin liquid is blocked by the blocking plug, a small amount of small tin slag solidified by the blocking plug will flow to the rear of the cavity, and will also be blocked by the filter cotton, at this time, since the tin slag has solidified, it will not adhere to the surface of the filter cotton, so as to avoid inconvenience for cleaning.

[0026] In addition, the material of the blocking plug 1 is high-temperature-resistant and fire-retardant rubber, which is used to replace the blocking plug in the original cavity of the tin suction device on the market.

[0027] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any change or replacement without creative labor is covered in the protection scope of the present application. Therefore, the protection scope of the present application should be limited by the protection scope defined in the claims.
