Description

Technical Field

[0001] The utility model belongs to the technical field of welding equipment, and specifically relates to a novel vacuum soldering iron. Background Art

[0002] Electric soldering iron is a very important tool in the process of electronic production and electrical appliance repair. It mainly uses molten solder wire to bond metal parts together to complete the connection of electronic circuits. At present, when using electric soldering iron to solder electrical components, tin has become an ideal choice for connecting electrical components, metal parts or other materials due to its low melting point and good fluidity.

[0003] However, since the commonly used soldering tin is a lead-tin alloy, it is easy to produce tin smoke containing lead due to the high temperature of the soldering iron during the soldering process, which can cause harm to the health of the operator. For this reason, existing welding workshops are generally equipped with ventilation systems, and the harmful gases are discharged to the outside through the smoke extractor, exhaust fan, exhaust hood or local exhaust system in the ventilation system, so as to effectively capture and filter the tin smoke in the air and improve the air quality of the working environment.

[0004] However, the above method still has certain disadvantages in actual application: 1. The initial cost of installing the ventilation system and using the smoking machine is extremely high, and there are subsequent regular maintenance costs, which is not suitable for some small manufacturers; 2. Each device in the ventilation system will produce different degrees of noise during operation, thereby affecting the operator's work comfort; 3. The ventilation system equipment needs to rely on a lot of electricity to maintain the operation of the equipment during use, and different types of models have different machine sizes. It is difficult to flexibly adjust according to the work area and it is easy to cause inconvenience to the operator. Utility Model Content

[0005] The technical problem solved by the utility model is to provide a new vacuum soldering iron with a tin smoke suction function, so that manufacturers can avoid operators being harmed by tin smoke during the welding process without adding high-cost system equipment and maintenance costs.

[0006] In order to solve the above technical problems, the technical solution provided by the utility model is as follows: a new vacuum soldering iron, which includes a soldering iron body, the rear end of which is connected to a connecting wire, which is connected to a power supply device; an internal channel is provided at the rear end of the handle of the soldering iron body, an air hole is penetrated between the inner wall of the internal channel and the surface of the handle, the end of the internal channel is connected to a gas delivery pipeline, and the end of the gas delivery pipeline is connected to a smoking mechanism. In this way, since the new vacuum soldering iron provided by the utility model has a smoking function, it can enable the operator to use the soldering iron itself to extract tin smoke when operating the electric soldering iron, without the need to set up other additional smoking equipment, thereby avoiding the inconvenience of operation caused by it, as well as the problems of high production cost and high maintenance cost caused by it.

[0007] Furthermore, the gas delivery pipeline is sleeved on the outside of the connecting line, and a gas delivery channel for delivering the absorbed gas is reserved between the gas delivery pipeline and the connecting line.

[0008] Furthermore, the smoking mechanism is arranged inside the power supply device to reduce the occupied space of the entire device and reduce the total number of devices.

[0009] Furthermore, an independent air hole opening and closing control switch is arranged outside the power supply device, and the independent air hole opening and closing control switch is used to control whether the smoking function of the entire electric soldering iron is turned on.

[0010] Furthermore, the smoking mechanism includes a vacuum chamber arranged in the power supply equipment, a vacuum device is installed on one side of the vacuum chamber, the air inlet end of the vacuum chamber is connected with the gas delivery pipeline through the suction channel, and an exhaust fan is arranged at the air outlet end of the vacuum chamber. At this time, the vacuum chamber in the utility model can maintain a vacuum state through the vacuum device, thereby ensuring that the smoke generated by the soldering iron body during the welding process can enter the vacuum chamber through the air holes, the internal channel, the gas delivery pipeline, and the suction channel in sequence.

[0011] Furthermore, the air hole opening and closing independent control switch is the control switch of the vacuum device, and the operator can control its working state by operating the control switch, that is, control whether the entire electric soldering iron turns on the smoking function.

[0012] Furthermore, a filtering mechanism is provided between the air inlet and the air outlet of the vacuum chamber, and harmful substances in the gas are filtered through the filtering mechanism.

[0013] Furthermore, the filtering mechanism includes at least one layer of filter cotton arranged in the vacuum chamber, and the harmful substances in the gas are filtered through the filter cotton.

[0014] Furthermore, the filtering mechanism includes at least two layers of filter cotton arranged in the vacuum chamber, all the filter cottons are made of different materials and filter different substances in the gas, so as to achieve the purpose of reducing harmful substances in the gas to the greatest extent.

[0015] Furthermore, the filtering mechanism includes three layers of filter cotton arranged in the vacuum chamber. The three layers of filter cotton are made of different materials and filter different substances in the gas, so as to achieve the purpose of reducing harmful substances in the gas to the greatest extent.

[0016] It can be seen from the above technical scheme that the utility model has the following advantages: the new vacuum soldering iron provided by the utility model has a suction function, and the operator can use the soldering iron itself to extract tin smoke when operating the soldering iron, without the need to set up other suction equipment, thereby avoiding the inconvenience of operation caused by it, as well as the problems of high production cost and high maintenance cost caused by it.
