New description: [New technical field] This creation is about a negative pressure gauge, especially a negative pressure gauge with switching. [Prior Art] When the general negative pressure gauge is used, it must be provided with a display unit that can display the gas flow rate, so that the user can adjust the flow rate of the gas flowing through the negative pressure = according to the actual use condition; the display unit can usually be divided into Pointer type and digital meaning, while digital display unit needs to supply power, so the power supply unit is usually set in the negative pressure gauge of the position display unit, and the battery is supplied to the negative pressure gauge. Gas gas = in the display unit. i ^ However, the structure of this negative pressure gauge still has one point in practical use: since the display unit is directly connected to the power supply unit, when the battery is mounted on the negative pressure gauge, the display unit will display the gas pressure value when used. ', = No unit does not have any power switch structure and the power supply unit is continuously powered. ' Even if the negative pressure iron is in the non-contained state, the display is single:: move, the solution to this problem is to unload the battery from the negative pressure gauge. However, the second work is quite labor-intensive, and when the negative pressure gauge is to be used, the battery is again set to 1. This will make the user feel quite inconvenient. The ^. 'How to improve the above problems, that is, the creator of this research 3 M357601 [new content] The purpose of this creation is to provide a switchable open meter, by switching the switch to make it negative or open, to save power The effect. In order to achieve the above objectives, the author provides a negative pressure gauge, including - body, - switch open clamp switch, a display module, power supply unit and a switch.

The effect achieved by this creation compared to the prior art is that it has the disadvantage of having a switch to keep the power supply unit in a power supply state = wasting power, and then picking up the goods gg - 杈 ί, 电 兀 兀 并 并 并 并 并 并The number of power supply units increases the ease of use. [Embodiment] The detailed description and technical contents of the present invention are as follows. However, the drawings are only for reference and explanation, and are not intended to limit the creation. M357601 is referred to the first figure as a three-dimensional exploded view of the creation. The creation system provides a negative pressure gauge with a switch, including a body 1〇, a positioning switch 20, a display module 3〇, and a power supply unit. The rib and a changeover switch 50, wherein: the body 10 is formed with an air flow passage n communicating with the outside, and an exhaust port 12 communicating with the air flow passage 11 and an air inlet 13. The rotary switch 2 includes a rotating body 21 pivotally connected to the body 1 , and the rotating body 21 is rotatably positioned relative to the body 10 ; the rotating body 21 is formed with a touching protrusion 211 and another touching protrusion 212 . The touch bump 211 is spaced apart from the touch bump 212. The display module 3 is mounted on the main body 1; the display module 3 includes a circuit board 3UX and a display panel % stacked on the circuit board 31. The display panel 32 is electrically connected to the circuit board 31. The circuit board 31 has a sensing unit, 3=, and the sensing unit 311 is partially received in the airflow channel n for sensing the gas pressure in the airflow channel 11, and displaying the pressure value on the display. Panel • 32. The power supply unit 40 is fixed to the back of the main body 10 and electrically connected to the display module 3 through an electrical circuit b (the first figure); the negative pressure table also includes a T-top over the dead body 10. An outer cover 6 and a flow regulating unit 7 are disposed on the body 1 〇 and partially accommodated in the air flow passage η, and the rotatable flow adjusting unit 70 controls the flow inlet flow passage 11 The size of the gas flow. The knife change switch 50 is disposed on the body 1 〇 and is corresponding to the touch Φ 211 of the rotating body μ, and the switch 5 〇 is mounted on the electric circuit ^ (see the second figure), 5 M3 57601 And in the normal state, the display module 30 and the power supply unit 4 are in an open state; When the rotating body 21 rotates relative to the body 1 , the switching switch 5 〇 will be triggered by the driving protrusion 211 , and the power supply unit 4 电 is electrically connected to the display module. Further, the switching switch 50 includes a connector 51 and a pivot. a switching unit 52 connected to the connection 51, a base 53 connected to the (4), and a base 53 for the connector 51 and the switching unit 52 are provided, and the switching unit is replaced. The 52 series is disposed corresponding to the touch bump 211, and the fixing component (4) fixes the base 53 to the body 丨0. The field switching unit 52 pulls the touch bump 211 and touches the bump 212, and the connector 51 connects the power supply unit The display module 30 is electrically connected to the display module 3, and the display module 30 is operated. The second figure is a schematic diagram of the creation circuit configuration, please refer to the first figure together, the power supply unit 40 and the display module 3 The switch is electrically connected through an electrical circuit b, and the switch 5 is mounted on the electrical circuit b; the sense engine 70 311 converts the sensed pressure value into a current signal and transmits it to the circuit board 31. The IL 汛 is transmitted to the connector η after being processed via the circuit board 31; When the swivel 21 is pulled, the switching unit 52 and the touch bump 211 and the touch bump 212 have three relationships, that is, the first: the touch bump 211 and the touch bump 212 do not abut the switching unit 52. Second, the touch bump 211 abuts the switching unit 52, and the third: the touch bump 212 abuts the switching unit 52. When neither the touch bump 2 nor the touch bump 212 abuts the switching unit 52, the power supply unit 40 and the display module 30 are in an open state, at this time, the display 6 M3 57601 board 32 is closed 'so the power of the power supply unit 40 is not lost; and the rotating side 21 is rotated to make the touch bump 211 and the switching unit 52 When the abutting or touching the bump 212 abuts the switching unit 52, the connector 51 of the switch 50 will be activated to electrically connect the power supply unit 4 to the display module, so that the sensing unit 311 detects The gas pressure value is displayed on the display panel 32. - See the second to fifth figures for the creation, the top view of the creation, the top view of the creation of the creation (-) and the top view of the creation of the creation _ one, see the third picture, can be seen from the picture The touch bump 211 and the touch bump 212 of the rotating body 21 are not in contact with the switching unit 52. At this time, the display panel 32 is in a closed state, and the gas pressure value measured by the sensing unit 311 will not be displayed. Display panel 32. Referring to the fourth and fifth figures, when the trigger lever 213 is pulled to rotate the rotating body 21 relative to the body 10, the contact protrusion & 212 will abut against the switching unit 52 to cause the switching unit 52 to be activated. When the connector 51 is turned on, the display panel 32 will be activated to display the gas pressure value; similarly, when the touch bump 211 Φ abuts the switching unit 52 and the (4) unit 52 is activated, the display panel 32 will be the same. The gas pressure value is activated to be activated; and the difference between the touch bump 211 and the touch bump 212 is that the display unit is in a different display mode to display the gas pressure value. In summary, when the negative pressure gauge with the switch is known to have industrial utilization, novelty and progress, the structure of the creation has not been seen in similar products and public use, and fully meets the requirements for new patent applications. Apply for an application under the Patent Law. M3 57601 [Simple description of the diagram] The first diagram is a three-dimensional exploded view of the creation.
