The front surface of the air pressure monitoring alarm is provided with multiple buttons for adjusting the alarm. The rear surface of the mounting plate 1 is provided with a quick-install component, which makes it easy to install the device on the wall.

[0033] Reference Figure 2 、 Figure 5 The front surface of the protective plate 42 is provided with a sealing component, which can seal the button to prevent moisture and dust from accumulating on the button and corroding the button, so as to protect the button.

[0034] Reference Figure 5The quick-release assembly also includes a valve core 35, and a one-way valve 36 is provided at the front end of the right surface of the hollow cylinder 31. The valve core 35 and the one-way valve 36 are existing technologies and can be implemented by technicians in this field. Since they are existing technologies, they will not be described in detail in this case. There is a valve nozzle on the valve core 35. Pressing the valve nozzle can allow air to circulate inside and outside the hollow cylinder 31. The one-way valve 36 can only allow air to circulate in one direction. The air in the hollow cylinder 31 can be discharged, and the external air cannot flow into the hollow cylinder 31 from the one-way valve 36. The valve core 35 is arranged at the front end of the right surface of the hollow cylinder 31, and the valve core 35 is located in front of the one-way valve 36.

[0035] Reference Figure 1 - Figure 3 The protective component also includes a shift block 45. The inner wall of the connecting plate 41 is elastically connected to the card block 44 through a compression spring 43. A card slot 401 is provided at the top of the right surface of the protective plate 42. The card block 44 fits into the card slot 401. The rear surface of the shift block 45 is fixedly connected to the front surface of the card block 44. Moving the shift block 45 can drive the card block 44 to move synchronously.

[0036] Reference Figure 1 、 Figure 4 The sealing assembly includes a sealing plate 51. The rear surface of the sealing plate 51 is hollow and will only contact the area around the button without hitting the button. The front surface of the protective plate 42 is rotatably connected to a threaded rod 53. The front surface of the threaded rod 53 is fixedly connected to a handwheel 52. The handwheel 52 is easy to grasp. Grasping the handwheel 52 and rotating it can drive the threaded rod 53 to rotate synchronously.

[0037] Reference Figure 1 - Figure 2 The hollow cylinder 31 passes through and is fixedly connected to the rear surface of the mounting plate 1. There are multiple groups of hollow cylinders 31, which are evenly distributed on the front surface of the mounting plate 1. The suction cup 32 is set to a cone shape. The slide rod 33 passes through and slides on the front surface of the hollow cylinder 31, sliding in the front and back directions. The outer wall of the slide rod 33 fits with the inner wall of the hollow cylinder 31 to maintain a seal. The rear surface of the connecting plate 41 is fixedly connected to the front surface of the slide rod 33. When the connecting plate 41 moves, it will drive the slide rod 33 to move synchronously.

[0038] Reference Figure 1 - Figure 3The block 44 is inserted into the inner wall of the slot 401, which can limit the protective plate 42. The upper surface of the block 44 is set to a plane. When the protective plate 42 is in the protective state, the lower surface contacts the upper surface of the block 44, and the block 44 can limit the protective plate 42. The block 44 passes through and is slidably connected to the left surface of the connecting plate 41, sliding horizontally. One end of the compression spring 43 is fixedly connected to the right surface of the block 44, and the other end of the compression spring 43 is fixedly connected to the inner wall of the right side of the connecting plate 41. When the block 44 moves to the right, it squeezes the compression spring 43 to produce a reaction force. The left surface of the block 44 is set to an inclined surface, and the inclined surface is located in the lower position. When squeezing the inclined surface of the block 44, the block 44 will move to the right, and the dial block 45 passes through and is slidably connected to the front surface of the connecting plate 41, which is convenient for dialing. Driving the dial block 45 will drive the block 44 to move synchronously.

[0039] Reference Figure 1 、 Figure 4 The sealing plate 51 passes through and is slidably connected to the front surface of the protective plate 42. The threaded rod 53 passes through and is threadedly connected to the front surface of the sealing plate 51. When the threaded rod 53 rotates, it can drive the sealing plate 51 to move in the front and rear directions. The rear surface of the sealing plate 51 is set to rubber material, and the rear surface of the sealing plate 51 is in contact with the front surface of the protective plate 42.

[0040] Working principle: When using this device, first align the suction cup 32 with the wall where it needs to be installed, then press the suction cup 32 against the wall to maintain a seal, and then move the connecting plate 41 forward. The connecting plate 41 will drive the multiple sets of slide bars 33 and rubber pads 34 to move forward. The rubber pads 34 moving forward will press the air inside the hollow cylinder 31 to be discharged from the one-way valve 36. Since the hollow cylinder 31 is in a sealed state and external air cannot enter, after the air inside the hollow cylinder 31 is discharged, the internal air pressure will be lower than the external air pressure, forming a negative pressure state. The suction cup 32 will adsorb the device tightly to the wall, and then the waterproof The guard plate 42 moves upward, and the upward moving guard plate 42 will squeeze the inclined surface of the block 44. The block 44 will retract into the connecting plate 41 to release the limit and squeeze the compression spring 43 to generate a reaction force. When the upper surface of the guard plate 42 contacts the connecting plate 41, the upper surface of the block 44 will be flush with the lower surface of the guard plate 42, and the squeezed state of the block 44 will be released. The reaction force of the compression spring 43 will push the block 44 to move to the left, and the block 44 will move to the lower surface of the guard plate 42 to block the guard plate 42 and prevent the guard plate 42 from sliding. At this time, the guard plate 42 will move to the front of the equipment body 2.

[0041] Then, the hand wheel 52 is rotated to drive the threaded rod 53 to rotate. The rotating threaded rod 53 will drive the sealing plate 51 to move backward. The sealing plate 51 moving backward will fit with the front surface of the device body 2 to maintain a seal, thereby making the buttons on the device body 2 waterproof and dustproof.

[0042] When it is necessary to adjust the device body 2, the dial block 45 can be moved to the right to drive the card block 44 to move to the right. The card block 44 moving to the right will squeeze the compression spring 43 to generate a reaction force and release the obstruction to the protective plate 42. The protective plate 42 can move downward. When the card slot 401 and the card block 44 are aligned, the reaction force of the compression spring 43 will push the card block 44 and the card slot 401 to plug into the protective plate 42 to limit the position of the protective plate 42, ensuring the stability of the position of the protective plate 42. At this time, the button on the device body 2 will be exposed, which is convenient for adjustment.

[0043] When the device needs to be removed from the wall, the valve nozzle on the valve core 35 is pressed to allow external air to flow into the hollow tube 31, so that the air pressure inside the hollow tube 31 is equal to the external air pressure, the negative pressure state is released, and the device can be removed.

[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
