The present application claims priority to and the benefit of Chinese Patent Application No. CN 201721194789.4 filed on Sep. 18, 2017, the entire contents of which are incorporated herein fully by reference.
The present disclosure generally relates to the technical field of welding protector, and more particularly, to a welding mask with a sensor lamp.
Weldment has been widely used in all walks of life. Since performance of the weldment is more reliable than that of a connector, and the weldment performs better in terms of utilization rate, it is important to guarantee the quality of the weldment.
At present, owing to different working conditions, in the case of bright light, the weldment can be seen clearly during welding to complete the welding operation. However, in the case of poor environment with weak light, it is barely possible for an operator to observe the weldment using his eyes only, and in such an environment with poor lighting, welding quality cannot be properly guaranteed, then it is thus desirable to develop a welding protector with a head lamp, especially a welding mask with the head lamp.
However, there are two types of welding masks with the head lamp available in the market: one is a chuck-typed, that is, the head lamp is gripped by a chuck whereby the head lamp is arranged on the welding mask, and switch-on and switch-off is controlled by an external switch; and the other is welding the head lamp on the welding mask directly, and switch-on and switch-off is done manually. However, problems listed as follows exist in those two types of welding masks. Too many components involved in these two types of welding masks, it is inconvenient to carry with, or manual operation is necessary for the control of the head lamp. In addition, during welding, since welding arc can compensate for the lack of light, it is a waste of electric energy if the head lamp is still on then.
Given that the foregoing problems exist in the prior art, the present disclosure provides a welding mask with a sensor lamp, that is, a head lamp is arranged on the component where lens of the welding mask is located, and is connected to a light sensing sensor, which will be switched on automatically in a weak light, while switched off automatically in an environment with bright light, whereby a modular head lamp is achieved, and electric energy can be saved a lot.
The specific technical schemes are as follows:
A welding mask with a sensor lamp, comprising: a mask shell, a filter module, a head lamp and a control switch, wherein the filter module is arranged on the mask shell, the head lamp is embedded in the filter module and is connected to a circuit board of the filter module; wherein,
the control switch comprises a mechanical switch and a sensing module, and both the mechanical switch and the sensing module are connected to the circuit board of the filter module.
The above welding mask with a sensor lamp, wherein the mask shell comprises a face portion and two side portions, and the face portion is just in front of eyes of an operator when in use, while the two side portions are disposed on either side of the face portion respectively.
The above welding mask with a sensor lamp, wherein the face of the mask shell is provided with a filter window, and the filter window is rectangular.
The above welding mask with a sensor lamp, wherein the mechanical switch is provided with a plurality of gears, one of the plurality of gears is a normally-off gear and another one of the plurality of gears is a normally-on gear, and another one of the plurality of gears is a sensing gear, and the mechanical switch in the sensing gear is connected to the sensing module.
The above welding mask with a sensor lamp, wherein the sensing module is embedded in the filter module, and the sensing module further comprises a light sensing sensor and a corresponding control circuit, wherein the light sensing sensor can sense the intensity of light in the exterior of the mask shell.
The above welding mask with a sensor lamp, further comprising a power supply, wherein the power supply is a rechargeable battery or a non-rechargeable battery.
The above welding mask with a sensor lamp, wherein the mechanical switch is a knob switch or a toggle switch.
The above welding mask with a sensor lamp, wherein the mechanical switch is provided with an anti-skid slot.
The above welding mask with a sensor lamp, wherein the filter module is also provided with an arc sensor, and the arc sensor is connected to the sensing module.
The above welding mask with a sensor lamp, wherein the sensing module is provided with a solar power utilization member.
The positive effects of the technical schemes are as follows: 1. the arrangement that the head lamp is provided on the filter module in the mask shell and is connected with the sensing module makes it possible to achieve the result: the head lamp will be turned on automatically in the environment with poor lighting, while turned off in the case of bright light, thereby effectively saving electric energy and making full use of resources in an more reasonable way; moreover, the sensing module is also provided with the solar power utilization member, having the ability to generate electric power through solar power, and to generate electric power by absorbing the bright light in welding, it is therefore more efficient in energy saving and environmental protection; 2. both the sensing module and the mechanical switch with a plurality of gears are provided, the welding mask can be more easily adapted to different environment, and it is possible to choose different gears depending on the environment, moreover, it is ensured that the head lamp cannot be turned on when the mechanical switch is off, and the arrangement of the plurality of gears prevents the head lamp being turned on automatically when not in use, therefore, higher security can be obtained; 3. since the head lamp is embedded in the lens module, degree of modularization is higher, and space is saved a lot; 4. arc sensor provided herein can assist the sensing module in sensing whether light is strong or weak, so that the accuracy of sensing is higher, and the intelligence level is improved further.
