Description

Technical Field

[0001] The utility model relates to a multifunctional handheld electric tool, which comprises a shell in the shape of a pistol, a lithium battery, a display screen, a mainboard, an air pump and a bendable multifunctional hose. Background Art

[0002] With the development of society, people's quality of life is constantly improving. Cockroaches, rats and termites often breed in places where people rest or gather, such as homes, restaurants or accommodations. These pests with strong reproductive capacity not only contaminate food with their excrement and spread germs, but also damage furniture and cables and even cause fires. Termites are insects that feed on wood. They dig holes inside the structure of a building and eat the wood, causing the structure of the building to become fragile or even collapse. In addition, termites can also destroy wooden products such as furniture, floors, and books, causing losses to people's lives and property. Therefore, in order to protect the integrity of buildings and wooden products and prevent the spread of diseases, termite extermination is very necessary. People can control and eliminate termites by taking chemical extermination, physical extermination, biological extermination and other methods.

[0003] At present, termites are mainly killed by airflow to flush powder from the powder bottle into mist and spray it out. The commonly used tool is an electric powder spray gun. The Chinese utility model patent application disclosure CN218736803U discloses a termite powder spray gun. The powder spray device includes a gun body, a chuck, a gun handle, etc. The detachable gun barrel facilitates the maintenance and maintenance of the powder spray gun. However, in daily actual use, after the professional has roughly determined the position of the termites, it is necessary to further determine the exact position of the internal termites through an endoscope, and then perform the powder spraying operation. This requires the professional to carry different tools for surveying and construction, which not only increases the cost, but also is inconvenient to carry. Therefore, it is necessary to optimize the traditional electric powder spray machine. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a multifunctional handheld electric tool. When the device is used to deal with termite disaster sites, not only can the location of the termite nest be accurately seen, but also insecticide powder can be sprayed synchronously to destroy the nest, which saves trouble and labor, has good effect and high efficiency.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a multifunctional handheld power tool, including a pistol-shaped shell, a lithium battery, a display screen, a main board, an air pump and a bendable multifunctional hose. A detachable powder storage bottle is provided on the shell, the main board is connected to the display screen and the air pump, the air pump controls the flow rate through a PWM speed regulator, and the display screen is connected to a camera installed at the end of the hose through the main board.

[0006] By setting a detachable powder storage bottle on the machine body, powder can be easily added for spraying. The mainboard distributes the signal, and the electrical signal from the camera is processed and input into the display screen to realize video imaging. Since the spray concentration and spray amount of the powder need to be strictly controlled for termite killing, too concentrated will block the ant tunnel, and too light will not achieve the killing effect. Therefore, the concentration of the spray powder is adjusted according to the actual situation and the properties of the drug. The speed of the air pump is controlled by the PWM speed regulator to adjust the force of the airflow impacting the powder, thereby controlling the spray powder concentration.

[0007] As an improvement of the utility model, a lighting switch and a focus switch for controlling the camera are provided on the lower side of the display screen, and the power is cut off by the on-screen switch. When such a switch is provided, not only can the power be turned off when no operation is required to prevent waste of electricity, but also the lighting switch can be conveniently used to adjust the light during use to illuminate and observe the interior of the termite nest, and the focus switch can also be used to adjust the focal length of the observation part of the camera extending into the termite nest to see more clearly.

[0008] As another improvement of the utility model, the lithium battery is set as a battery pack that can be used for the hand drill by inserting it into the shell through a buckle. Since professionals carry a large number of related tools when performing termite extermination operations on site, lithium batteries are the most convenient for power supply for different indoor and outdoor occasions. With such a detachable buckle structure, the battery can be quickly replaced for charging, and it is convenient for maintenance. There will be no trouble of the whole machine being unable to be used due to battery failure during long-term use. The convenient replacement of batteries also greatly reduces the cost of the whole machine, and the working battery life can also be guaranteed.

[0009] When the utility model is further improved, a powder spraying pipe machine video signal line is provided inside the hose, one end of which can be connected by a screw thread and a camera at the other end is arranged behind the powder spraying pipe to prevent powder from covering the camera. This is not only light and durable to use, convenient for storage, and low in production cost, but also the actual situation inside the nest captured by the camera can be directly sprayed with powder to destroy the nest according to the judgment of professionals, achieving the goal of destroying termites as soon as they are seen, greatly improving the killing effect and efficiency of termites, and having a simple structure and low cost, which is easy to promote and popularize.
