Description

Technical Field

[0001] The utility model relates to the technical field of buzzer mechanisms, in particular to a buzzer alarm mechanism and a pneumatic sweeper. Background Art

[0002] A pneumatic sweeper is a professional, environmentally friendly industrial cleaning device that collects scrap metal and residual liquids directly into a hopper, eliminating dust and polluting the environment. A buzzer is an integrated electronic sounder commonly used as a sounding device in mechanical and electronic equipment such as computers and industrial automation equipment.

[0003] When a pneumatic sweeper is cleaning metal dust, debris and residual liquid on the floor of a workshop or machining center, it collects impurities into the hopper. If too much impurities accumulate inside the hopper and are not cleaned in time, it will cause blockage. However, since the hopper is set inside the pneumatic sweeper, the amount of impurities in the hopper cannot be directly observed. Therefore, the cleaning efficiency of the pneumatic sweeper is often affected by the excessive amount of impurities that are not cleaned in time, and even the pneumatic sweeper is damaged. At the same time, since the buzzer alarm mechanism generates sound through vibration, it will generate static electricity, which will absorb dust when in use, affecting the buzzer effect, and is more troublesome to clean. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the utility model provides a buzzer alarm mechanism and a pneumatic sweeper to solve the above technical problems existing in the existing technology.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a buzzer alarm mechanism and a pneumatic sweeper, including a mounting frame, a buzzer mechanism base is provided at the top of the mounting frame, a vibrator is provided at the top of the buzzer mechanism base, a protective cover is provided at the top of the buzzer mechanism base outside the vibrator, and an adsorption cover is provided at the top of the buzzer mechanism base between the protective cover and the vibrator; a wire is provided at the bottom of the buzzer mechanism base, a supporting base is provided at the extending end of the wire, an impurity storage box is provided at the top of the supporting base, a pressure sensor is provided at the top of the supporting base at the bottom end of the impurity storage box, and the wire is externally connected to a controller.

[0006] Furthermore, two limiting blocks are provided at the bottom end of the impurity storage box, and two slots are provided at the top end of the supporting base at positions corresponding to the limiting blocks. The impurity storage box is limited by the slots through the limiting blocks, ensuring that the impurity storage box can be fixed at a predetermined position without displacement.

[0007] Furthermore, four clip-on frames are provided at the upper edge of the outer surface of the adsorption cover, and four limit frames are provided at the lower edge of the outer surface of the adsorption cover, so that the adsorption cover can be fixed. The adsorption cover is preferably a metal filter screen to block dust.

[0008] Furthermore, four positioning clamps are provided at the corresponding positions of the top of the buzzing mechanism base and the limit frame, and the upper part of the outer surface of the protective cover is threadedly connected with an upper cover. The four positioning clamps are adapted to the limit frame, and the limit frame has a limiting effect on the adsorption cover.

[0009] Furthermore, the inner wall of the upper cover is provided with a cavity adapted to the clamping frame. When the upper cover is installed, the upper cover will fix the clamping frame through the cavity, so that the adsorption cover will not shake or deform.

[0010] A pneumatic sweeper comprises a sweeper body, on which the buzzer alarm mechanism is provided.

[0011] Furthermore, the supporting base is fixedly installed inside the sweeper body, and a switch door is provided at the front end of the sweeper body near the supporting base. When the impurity storage box needs to be taken out, the switch door is opened and the impurity storage box is pulled outward to facilitate cleaning of the dust inside the impurity storage box.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The pneumatic sweeper of the present application is provided with the above-mentioned alarm mechanism. When the sweeper is in operation, it absorbs impurities through the dust suction port. The impurity storage box is connected to the dust suction port through a pipe. The dust suction port absorbs the impurities into the impurity storage box for collection. When the impurity storage box is placed on the top of the supporting base, the pressure sensor contacts the bottom of the impurity storage box to detect the weight of the impurity storage box. The controller is electrically connected to the pressure sensor, and then the force range of the pressure sensor is set by the controller. When the weight of the dust stored inside the impurity storage box reaches the rated weight, the controller will send an electromagnetic signal through the base of the wire buzzing mechanism, causing the vibrator to run and sound an alarm, so that the operator knows that the impurity storage amount inside the impurity storage box has reached the limit and cleans it in time to avoid affecting the cleaning efficiency of the pneumatic sweeper or damaging the pneumatic sweeper.

[0014] 2. The buzzer alarm mechanism of the present application is provided with an adsorption cover. Since static electricity is generated when the vibrating diaphragm vibrates, the static electricity produces an attractive force on the dust. The adsorption cover is a metal filter that blocks the dust, preventing impurities from sticking to the surface of the vibrator and affecting the alarm effect. At the same time, it is easy to disassemble and clean. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The technical solution of the present invention will be described clearly and completely below with reference to the accompanying drawings and specific embodiments.

[0022] A wire 4 is provided at the bottom of the buzzer mechanism base 9, and the wire 4 extends from top to bottom to the inside of the sweeper body 1, and a bearing base 6 is provided at the extended end of the wire 4. The top of the bearing base 6 is provided with an impurity storage box 8, and a pressure sensor 17 is provided at the middle position of the top of the bearing base 6 at the bottom of the impurity storage box 8. The outside of the wire 4 is connected to the controller 5. The model of the pressure sensor 17 is preferably L10A-2kg. The top of the pressure sensor 17 is an arc-shaped component. When the impurity storage box 8 is placed on the top of the bearing base 6, the pressure sensor 17 contacts the bottom of the impurity storage box 8 to detect the weight of the impurity storage box 8; the controller 5 is electrically connected to the pressure sensor 17, and then the force range of the pressure sensor 17 is set by the controller 5. When the weight of the dust stored inside the impurity storage box 8 reaches the rated weight, the controller 5 will send an electromagnetic signal through the wire 4 buzzer mechanism base 9, so that the vibrator 10 can run and sound an alarm, so that the operator knows that the impurity storage amount inside the impurity storage box 8 has reached the limit and can clean it in time to avoid affecting the cleaning efficiency of the pneumatic sweeper or damaging the pneumatic sweeper.

[0023] Specifically, the supporting base 6 is fixedly installed inside the sweeper body 1, and a switch door 3 is provided at the front end of the sweeper body 1 near the supporting base 6. When the impurity storage box 8 needs to be taken out, the switch door 3 is opened and the impurity storage box 8 is pulled outward to facilitate cleaning the dust inside the impurity storage box 8.

[0024] Furthermore, two limit blocks 18 are provided at the bottom end of the impurity storage box 8, and two slots 7 are provided at the top of the supporting base 6 at positions corresponding to the limit blocks 18. The impurity storage box 8 is limited by the slots 7 through the limit blocks 18, ensuring that the impurity storage box 8 can be fixed in a predetermined position without displacement.

[0025] Furthermore, four clip frames 13 are provided at the upper edge of the outer surface of the adsorption cover 15, and four limit frames 12 are provided at the lower edge of the outer surface of the adsorption cover 15, so that the adsorption cover 15 can be fixed. The adsorption cover 15 is a metal filter screen, which has a dust blocking effect.

[0026] Furthermore, four positioning clamps 11 are provided at positions corresponding to the top of the buzzer mechanism base 9 and the limiting frame 12 . The four positioning clamps 11 are adapted to the limiting frame 12 , and the limiting frame 12 has a limiting effect on the adsorption cover 15 .

[0028] The method of using this embodiment is as follows: when using a pneumatic sweeper to clean metal dust, debris and residual liquid on the floor of a workshop or a machining center, the sweeper will absorb the dust through the dust suction port, and the impurity storage box 8 is connected to the dust suction port through a pipeline. The dust suction port absorbs the dust into the impurity storage box 8 for collection. When the impurity storage box 8 is placed on the top of the supporting base 6, the pressure sensor 17 contacts the bottom of the impurity storage box 8 to detect the weight of the impurity storage box 8; the controller 5 is electrically connected to the pressure sensor 17, and then the controller 5 sets the force range for the pressure sensor 17. When the impurity storage box 8 is placed on the top of the supporting base 6, the pressure sensor 17 contacts the bottom of the impurity storage box 8 to detect the weight of the impurity storage box 8; the controller 5 is electrically connected to the pressure sensor 17, and then the controller 5 sets the force range for the pressure sensor 17. When the weight of the dust stored inside the box 8 reaches the rated weight, the controller 5 will send an electromagnetic signal through the wire 4 and the buzzer mechanism base 9, causing the vibrator 10 to run and sound an alarm, so that the operator knows that the impurity storage amount inside the impurity storage box 8 has reached the limit and needs to be cleaned in time; the buzzer alarm mechanism drives the vibrating diaphragm to vibrate periodically and make a sound through the magnetic field emitted by the electromagnetic coil inside the vibrator 10. Since static electricity is generated when the vibrating diaphragm vibrates, the static electricity produces an attractive force on the dust. The adsorption cover 15 is a metal filter that will block the dust and prevent impurities from sticking to the surface of the vibrator 10 and affecting the alarm effect.
