Description

Technical Field

[0001] The utility model relates to an electric sprayer for spraying powder and liquid, which comprises a shell, a lithium battery, an air pump, a powder spraying pipe, an air jet nozzle and a medicine tank connected by threads. Background Art

[0002] Termites are a kind of pests that are destructive to buildings and wood. They will build nests in wood and reproduce, which will cause wood decay and structural damage. First of all, termites reproduce very quickly. Once they are discovered, they may have caused serious damage. Therefore, regular termite control can effectively prevent and control the reproduction of termites. Secondly, termites are very destructive to buildings and wood. If they are not controlled in time, they may cause structural instability of buildings and even threaten people's lives. Therefore, termite control is an important measure to ensure the safety of buildings and extend the service life of wood. People can control and eliminate termites by taking chemical control, physical control, biological control and other methods.

[0003] At present, there are two main ways to spray drugs to kill termites. One is to spray the powder from the powder bottle into a mist by airflow to kill termites. The commonly used tool is an electric powder spray gun. The Chinese utility model patent CN204466712U discloses an electric powder sprayer for preventing and controlling vegetable pests and diseases in facilities. The powder spraying device includes a powder spraying tube, a powder storage tank, a handle, etc. The impeller is driven by an infinitely fast motor to generate wind force. The powder in the powder storage tank is sucked into the powder spraying pipe by the wind and blown out. This powder spraying is suitable for open spaces. Pests such as termites hiding in wood or soil cannot be sprayed through the side. Moreover, in daily actual use, professionals not only need to retain and spray liquid to pre-treat the surface of buildings or furniture that need to be controlled, but also need to spray a large number of termites with powder after discovering termite nests. How to use a tool that can spray liquid on termite work sites and spray powder to kill termites in nests has become a difficult problem in the industry. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide an electric sprayer for spraying powder and liquid. When the device is used to deal with termite disaster sites, not only can the liquid spraying operation be carried out at any time, but also insecticide powder can be used to spray and destroy the nest with the same tool, which not only saves trouble and labor, but also has good effect and high efficiency.

[0005] In order to achieve the above-mentioned purpose, the utility model discloses an electric sprayer for powder spraying and liquid spraying, comprising a shell, a lithium battery, an air pump, a powder spraying pipe, an air nozzle and a medicine tank connected by a thread. A main body part connected to the medicine tank at the front end of the shell is provided with a powder outlet hole which is transparent to the outside world. A detachable upper water pipe is provided at the powder outlet hole. A one-way valve is provided on the upper water pipe to prevent the medicine liquid from flowing back. A bendable powder spraying pipe is connected to the front end of the main body part, and a spray head for spraying water mist is provided at the end of the powder spraying pipe.

[0006] By arranging a detachable medicine tank on the shell, it is convenient to add or supplement medicine powder or liquid medicine. A main body part connected to the medicine tank at the front end of the shell is provided with a powder outlet hole which is transparent to the outside world, so that after the airflow sprayed by the air jet nozzle impacts the medicine powder into powder mist, the powder mist is sprayed out from the powder outlet hole, and a detachable upper water pipe is provided at the powder outlet hole, and a one-way valve is provided on the upper water pipe. Under the action of the airflow of the air jet nozzle, the air pressure in the medicine tank is much greater than the external air pressure. Under the action of the air pressure, the liquid medicine in the medicine tank passes through the upper water pipe, passes through the bendable powder spraying pipe, and is sprayed out from the spray head to form a medicine mist. The setting of the one-way valve can prevent the liquid medicine from flowing back. When the air pump stops working, the upper water pipe is always kept with liquid medicine, so as to speed up the spraying speed at the start.

[0007] As an improvement of the utility model, the upper water pipe is set to a tight fit or snap-on structure, which is convenient to remove when spraying powder, and the powder outlet hole is reserved for use when spraying dry fine powder, and is installed for water supply when spraying liquid medicine. When this connection structure is set, not only is the upper water pipe easy to install when spraying liquid medicine, but also has good air tightness, it is also convenient to disassemble when spraying powder.

[0008] As another improvement of the utility model, the spray head is connected to the powder spraying tube through a thread, and the spray head is removed when spraying dry fine powder, and installed when spraying liquid medicine, for atomization of liquid medicine. The spray head is connected to the powder spraying tube through a thread, which can increase air tightness and increase the spray effect. If dry fine powder needs to be sprayed, the spray head can be unscrewed, which is simple and convenient, and has wide practicality.

[0009] When the utility model is further improved, a main board for managing the circuit can be provided at the end of the shell, and a socket for charging can be provided on the outer surface of the shell, and a switch for controlling start and stop can be provided on one side of the handheld part of the shell, which is convenient for charging and start and stop control. The switch can be a self-locking switch or a micro switch. If it is a self-locking switch, it is suitable for spraying for a longer time, and there is no need to press the switch all the time. If it is a micro switch, it is suitable for point-by-point spraying, which can be sprayed once pressed. This is not only light and durable to use, but also convenient for storage and low in production cost. According to the judgment of professionals, powder can be directly sprayed to destroy the nest, or termite control and retention spraying liquid can be used for termite prevention treatment, which greatly improves the killing effect and efficiency of termites. The structure is simple and the cost is low, which is convenient for popularization. BRIEF DESCRIPTION OF THE DRAWINGS
