Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a sprayer. Background Technology

[0002] Sprayers are very common in agriculture today. They are mainly used for spraying irrigation, weeding, and pest control in farmland, orchards, etc. For example, a sprayer disclosed in Chinese Patent (authorization announcement number: CN223209672U) includes a barrel body. The barrel body is provided with a handle, a cushion, and a shoulder strap fixing part. The handle, cushion, and shoulder strap fixing part are all located on the back of the barrel body and are arranged vertically. There are two shoulder strap fixing parts, which are located on both sides of the cushion. The top of the handle extends out of the top of the barrel body, and a grip hole and two shoulder strap fixing holes located on both sides of the grip hole are opened on the extended part. The shoulder strap fixing holes and the shoulder strap fixing parts are arranged vertically and vertically respectively.

[0003] In conjunction with paragraphs 0023 and 0024 of the aforementioned prior art and appendices Figure 3 It is known that the disclosed bucket body comprises three parts: the bucket body, the base, and the bottom cover. The base and bucket body are detachably connected, and the base has a dedicated battery compartment. In other words, the structure employs a modular design to form the complete bucket body, with the base used to separately store the battery, water pump, and other electronic components. Due to the significant weight of the batteries and other components, and the fact that the base is located below the bucket body, the connection strength between the bucket body and the base requires extremely high strength. While the prior art does not specifically describe the connection method in its text, it can be inferred from the attached document. Figure 1-3 As can be seen, the base is pre-fixed by snapping together with the opening at its top and the snap-edge at the bottom of the barrel. Then, the pad is screwed to the barrel body and the side wall of the base with screws to ensure a stable connection between the two.

[0004] However, in practice, this connection method cannot effectively guarantee the reliability of the connection between the bucket body and the base. Especially when the user lifts the bucket by applying force to the handle, the base, due to the numerous internal components, always has a downward vertical force. Although there is a backrest and screws to lock the two together, the actual force only exists on one side wall of the bucket body and the base, resulting in poor connection reliability. Secondly, regarding the manufacturing of the bucket body, as an injection molded part, it requires at least three molds to manufacture the bucket body, base, and bottom cover separately, resulting in high production costs. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a sprayer. The technical problem this invention aims to solve is: how to improve the assembly stability of electronic control components while reducing production costs.

[0006] The purpose of this utility model can be achieved through the following technical solution: A sprayer includes a barrel, a battery, and a pump body, characterized in that the sprayer further includes a cover plate, a mounting recess is provided on one side of the outer wall of the barrel, the battery and the pump body are both connected and fixed to one side of the cover plate, the cover plate and the barrel are detachably connected and the mounting recess is sealed, so that the battery and the pump body are both located in the mounting recess.

[0007] The difference between this application and the prior art lies in the following: This application abandons the split barrel structure used in the prior art, and instead directly injection molds the barrel through a mold, making the formed barrel a one-piece structure. This reduces the number of molds required in the manufacturing process, thereby reducing production costs. Based on this structure, during the molding process, mounting recesses are directly formed on the outer wall of the barrel. On this basis, the pump body and the battery for powering the pump body are integrated into the cover plate. While the cover plate closes the mounting recesses, the mounting recesses also contain the battery and pump body, effectively isolating them from the outside world. With the battery and pump body effectively protected, the structural strength of the barrel itself is used to resist the gravity of the battery and pump body, thereby ensuring the stability of the assembly.

[0008] In the aforementioned sprayer, the cover is a U-shaped cover, and the mounting recess is located near the middle of the side wall of the barrel, extending through both the left and right side walls of the barrel. As a further embodiment, the mounting recess is positioned near the middle of the barrel in the height direction, ensuring that the battery and pump have minimal impact on the barrel's center of gravity after installation. Furthermore, extending the mounting recess through both sides of the barrel facilitates easy disassembly and assembly during subsequent maintenance and repairs, improves overall product consistency, and reduces mold processing difficulty. Additionally, the cover is adaptively shaped into a U-shape to ensure a good fit between the cover and the mounting recess, allowing the battery and pump to be fully concealed.

[0009] In the aforementioned sprayer, the left and right outer walls of the barrel have elongated positioning plates (first type). Both positioning plates (first type) are arranged along the height of the barrel and located on either side of the mounting recess. The cover plate has elongated positioning plates (second type) on both sides, also arranged along the height of the barrel. Each positioning plate (first type) and each positioning plate (second type) abuts against each other and is secured with screws. This design ensures stable connection between the cover plate and the barrel during installation, specifically by the corresponding abutments of the two positioning plates (second type) on the sides of the cover plate and the two positioning plates (first type) on the sides of the barrel, and by securing them together with screws. This guarantees effective protection for the battery and pump within the mounting recess.

[0010] In the aforementioned sprayer, the barrel body has an abutment edge arranged around the mounting recess. One circumferential edge of the cover plate abuts against the abutment edge, and the other side is flush with the outer wall of the barrel body. As a further solution, this application, by providing the abutment edge, allows the cover plate to abut against the abutment edge on one side during installation, using the abutment edge as a support to pre-position the cover plate, ensuring rapid assembly. Furthermore, after assembly, the other side of the cover plate is flush with the outer wall of the barrel body, thereby ensuring a higher degree of uniformity in the barrel's appearance.

[0011] In the aforementioned sprayer, the pump body and the battery are arranged laterally at intervals within the mounting recess. The pump body and the battery are connected by wires, and the pump body is connected to the cavity of the tank via a pipe. This arrangement rationally arranges the battery and pump body while ensuring unobstructed water flow, thereby ensuring the balance of the tank.

[0012] In the aforementioned sprayer, a disassembly port is provided on one side of the cover plate, which is positioned directly opposite the outer end of the battery. A protective cover for sealing the battery is detachably connected to the disassembly port. This design allows the user to expose the battery through the disassembly port by removing the protective cover, facilitating battery replacement without the need to completely disassemble the cover plate, thus making the operation more convenient.

[0013] Compared with existing technologies, this sprayer has the following advantages: It adopts an integrated barrel structure instead of the split barrel structure in existing technologies, thereby reducing the number of molds required for production and thus reducing production costs. Secondly, during the barrel molding process, mounting recesses are directly formed on the outer wall of the barrel to accommodate components such as the pump body and battery. Furthermore, the cover plate and barrel body are screwed together, ensuring that the pump body and battery are effectively protected while being installed stably. Attached Figure Description

[0020] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0021] like Figure 1 and Figure 2 As shown, this sprayer includes a battery 2, a pump body 3, and a vertically arranged tank 1. The tank 1 has an internal cavity for storing a solution. A mounting recess 11 is provided on one outer wall of the tank 1. Specifically, the mounting recess 11 is located near the middle of the side wall of the tank 1 and extends through both the left and right side walls of the tank 1. Figure 5 The sprayer also includes a cover plate 4, which is specifically a U-shaped cover. The pump body 3 is fixed to one side of the cover plate 4 by a bracket. A battery box is also fixed on this side of the cover plate 4. The battery 2 is detachably installed in the battery box. The battery box is specifically arranged horizontally at intervals with the pump body 3.

[0022] Combination Figure 3The barrel body 1 is also provided with an abutment edge 13, which specifically surrounds the mounting recess 11. During installation, specifically after the battery 2 and pump body 3 are assembled onto the side of the cover plate 4, the user places the cover plate 4 on the barrel body 1, so that the circumferential edge of one side of the cover plate 4 containing the battery 2 and pump body 3 abuts against the abutment edge 13. The mounting recess 11 accommodates the pump body 3 and battery 2, and the other side of the cover plate 4 is flush with the outer wall of the barrel body 1. The mounting recesses 11 are correspondingly provided on the two side walls of the barrel body 1. The two sides of the cover plate 4 are integrally formed with elongated positioning plates 12. Both positioning plates 12 are arranged vertically. The two sides of the cover plate 4 are integrally formed with elongated positioning plates 41. Both positioning plates 41 are also arranged vertically. After the above-mentioned fastening operation is completed, the two positioning plates 12 and the two positioning plates 41 can abut against each other in a corresponding manner and then be locked with screws to achieve the positioning of the cover plate 4, thereby ensuring that the barrel 1 can effectively accommodate the battery 2 and the pump body 3 through the installation notch 11.

[0023] Combination Figure 4 A disassembly port 42 is provided on the outer wall of the cover plate 4. The disassembly port 42 is arranged directly opposite the opening of the battery 2 and the battery box. A protective cover 421 is installed in the disassembly port 42 by means of a snap-fit ​​connection. The protective cover 421 seals the outer end of the battery 2 in the battery box. In subsequent use, especially when the battery 2 is depleted, the user can open the disassembly port 42 by removing the protective cover 421, so that the outer end of the battery 2 is exposed. This allows the battery 2 to be replaced without removing the cover plate 4, making the operation more convenient.
