[0026] Refer to Figure 1 、 Figure 2, this embodiment discloses a backpack - type electric sprayer with a stirring function, which includes a sprayer body. The sprayer body includes a kettle body 1, a kettle cavity arranged inside the kettle body 1, and a top cover 2 located on the surface of the kettle body 1. A stirring device is arranged inside the kettle body 1. The stirring device includes an electric drive component connected to the top cover 2, and a stirring component 4 arranged at the lower end of the electric drive component and located inside the kettle cavity. The stirring component 4 includes a rotating shaft 41 arranged inside the kettle cavity and several stirring rods 42 arranged on the rotating shaft 41. The electric drive component can drive the rotating shaft 41 and the stirring rods 42 to rotate inside the kettle cavity. There are two stirring components 4, located on both sides inside the kettle cavity, and the two stirring components 4 can be driven and stirred in sequence during the stirring process.

[0027] Refer to Figure 2 , the electric drive component is detachably connected to the top cover 2. During use, the motor drive component 3 can be installed on the top cover 2. When the stirring is completed, the motor drive component 3 can be removed, which can reduce the weight of the entire kettle body 1, and then reduce the burden on the staff. The electric drive component includes a motor head 31 detachably connected to the top cover 2 and an output shaft 32 arranged at the lower end of the motor head 31 and detachably connected to the rotating shaft 41. A cross - slot 9 is arranged at the top end of the rotating shaft 41, and a cross - convex block adapted to the cross - slot 9 is arranged at the bottom end of the output shaft 32. Through the assembly between the cross - convex block and the cross - slot 9, the connection between the output shaft 32 and the rotating shaft 41 is realized.

[0028] Handle covers 10 are detachably connected to both sides of the top cover 2. Specifically, the handle covers 10 can be detachably connected to the top cover 2 through common connection structures such as buckles or magnets. An installation hole 5 (the installation hole 5 is a countersunk - head hole structure) through which the rotating shaft 41 and the connecting rod can pass is arranged through the top cover 2. An installation plate 6 is detachably arranged inside the installation hole 5. The installation plate 6 is rotatably connected to the rotating shaft 41 (specifically, the rotation connection can be realized through connection structures such as bearing structures, and the entire rotating shaft 41 is supported by the installation plate 6). The installation hole 5 is located below the handle cover 10. When the stirring device is not in use, the handle cover 10 can cover the installation hole 5.

[0029] In order to realize the positioning between the installation plate 6 and the installation hole 5, a positioning component is arranged between the installation plate 6 and the installation hole 5. The positioning component includes a positioning groove 8 arranged on the inner wall of the installation hole 5 and a positioning strip 7 arranged on the side wall of the installation plate 6 and adapted to the positioning groove 8. The number of the positioning strip 7 and the positioning groove 8 is designed according to the actual situation. In this embodiment, both the positioning strip 7 and the positioning groove 8 are arranged in two. Through the cooperation between the positioning groove 8 and the positioning strip 7, the positioning installation between the installation plate 6 and the installation hole 5 is realized.

[0030] Working principle: When stirring the liquid is required, the user can first remove the handle cover 10, then closely fasten the bottom of the motor head 31 to the mounting hole 5, and ensure that the cross bump on the output shaft 32 is precisely adapted to the cross groove 9 of the rotating shaft 41. After the installation is completed, start the motor, and the motor drives the rotating shaft 41 and the stirring rod 42 to rotate through the output shaft 32, thereby realizing the stirring operation of the liquid in the kettle body 1. After the stirring is completed, the user can easily remove the motor head 31 and cover the handle cover again to effectively prevent foreign impurities from entering the kettle body 1.

[0031] If the stirring assembly 4 needs to be cleaned or replaced, the user can open the handle cover again and take out the mounting plate 6 from the mounting hole 5. During this process, the rotating shaft 41 and the stirring rod 42 will be taken out of the kettle cavity through the mounting hole 5 synchronously with the mounting plate 6, so as to facilitate the cleaning or replacement operation.

[0032] In addition, to facilitate the proper storage of the motor head 31 when the backpack electric sprayer is not in use, a storage device 11 is specially provided on the side wall of the kettle body 1, and a storage groove is equipped inside. The user can easily insert the motor head 31 into the storage groove to achieve convenient storage, thereby ensuring the cleanliness and safety of the device.

[0033] Through the operation of the motor drive assembly 3, the stirring assembly 4 can perform efficient and uniform stirring work. Since the stirring assembly 4 is completely placed inside the kettle body 1, compared with the traditional manual stirring method using tools such as branches, wooden sticks or metal pipes, it will not bring solid impurities into the kettle cavity, thereby significantly reducing the risk of blockage of the spray pipe or nozzle. In addition, the stirring efficiency and effect of this device are better than the traditional stirring method.

[0034] Refer to Figure 3 , to further prevent impurities from entering the spray pipe, a filtering device is specially provided at the position of the water outlet 12 at the bottom of the kettle cavity. This device consists of a filter sheet 13 and an elastic band 14 inside the water outlet 12. One end of the elastic band 14 is connected to the filter sheet 13, and the other end is connected to the position of the water outlet 12 (while Figure 3 in which the elastic band 14 is disconnected from the position of the water outlet 12 is only for clearer structural display and is not actually disconnected), and the material of the elastic band 14 is selected as anti-corrosive rubber to ensure the stable connection between the filter sheet 13 and the water outlet 12. The filter sheet 13 has a significant filtering effect, and the use of the elastic band 14 further strengthens the sealing between the filter sheet 13 and the water outlet 12. When the filter sheet 13 needs to be cleaned, only need to gently take out the filter sheet 13 from the water outlet 12 and stretch the elastic band 14 appropriately (the elastic band 14 is not separated from the filter sheet 13), then the filter sheet 13 can be cleaned, and then it will automatically reset under the elastic force of the elastic band 14.

[0035] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
