Description

Technical Field

[0001] The utility model belongs to the technical field of sprayers and relates to a sprayer. Background Art

[0002] A sprayer is a device that atomizes liquid or solid particles into tiny particles. It has a wide range of applications. For example, it can be used for spray irrigation, weeding, pest control, etc. in farmland, orchards, etc., to improve the yield and quality of crops.

[0003] A Chinese patent document discloses a backpack sprayer (application number: 201420570299.X), which includes a liquid storage tank and a pressurizing device. A shoulder strap is provided on one side of the liquid storage tank, and the shoulder strap includes a strap that surrounds the human waist and a single shoulder strap. The liquid storage tank is provided with a first slide groove that cooperates with the strap. The outer wall of the liquid storage tank is provided with a limit mechanism that limits the liquid storage tank from sliding around the strap. A connecting mechanism is provided between the two ends of the strap and is fixed by the connecting mechanism. One end of the single shoulder strap is integrally arranged with the portion of the strap close to the liquid storage tank, and the other end of the single shoulder strap is provided with a connector, which is connected to the portion of the strap away from the liquid storage tank.

[0004] The backpack sprayer has the following disadvantages when in use: the backpack sprayer can only be used by being carried on the back, and when carried on the back, the two straps must be wrapped around the user's body respectively, and the single shoulder strap must be passed around the user's shoulder. In addition, the user's back is in direct contact with the sprayer, making the backpack sprayer less convenient and comfortable to use. Summary of the Invention

[0005] The purpose of the present invention is to solve the above problems in the existing technology and to provide a sprayer. The technical problem to be solved by the present invention is how to improve the convenience and comfort of using the sprayer.

[0006] The purpose of this utility model can be achieved through the following technical solutions:

[0007] A sprayer comprises a barrel body, characterized in that the barrel body is provided with a handle plate, a cushion and a strap fixing part, the handle plate, the cushion and the strap fixing part are all arranged on the back of the barrel body and are arranged in sequence up and down, there are two strap fixing parts and they are respectively located on both sides of the cushion, the top of the handle plate extends out of the top of the barrel body, and a gripping hole and two strap fixing holes respectively located on both sides of the gripping hole are opened on the protruding part, and the strap fixing holes and the strap fixing parts are arranged one by one in correspondence up and down.

[0008] The sprayer has two strap fixing holes on the handle plate, and two strap fixing parts are provided on the barrel body, which correspond to the strap fixing holes one by one, so that the sprayer can adopt a traditional single-shoulder strap or double-shoulder strap. Specifically, when in use, the two ends of the single-shoulder strap are respectively hung on the two strap fixing holes, and the two ends of the double-shoulder strap are respectively hung on the corresponding strap fixing holes and strap fixing parts, so that the user can flexibly choose to set the existing single-shoulder strap or double-shoulder strap according to the use requirements. At the same time, the handle plate is also provided with a gripping hole, which is convenient for the user to carry the barrel body. In addition, a cushion is provided on the back of the barrel body, and the user's back rests on the cushion when carrying it, thereby improving the convenience and comfort of using the sprayer.

[0009] In the aforementioned sprayer, a receiving groove is formed on the back of the barrel body, and the handle plate is detachably connected to the groove wall of the receiving groove by a plurality of bolts. The thickness of the handle plate is less than or equal to the depth of the receiving groove, and the top of the handle plate extends out of the receiving groove. The handle plate is connected to the groove wall of the barrel body receiving groove by bolts, which facilitates disassembly, assembly and replacement, and provides good stability of the handle after connection. At the same time, the thickness of the handle plate is less than or equal to the depth of the receiving groove, which prevents the handle plate from hitting the back during carrying, thereby improving the user's carrying comfort.

[0010] In the aforementioned sprayer, the barrel comprises a barrel body and a cylindrical base detachably disposed below the barrel body. The base has an open bottom and a detachable bottom cover for sealing the opening. This structure allows for quick disassembly and maintenance of components such as the water pump, pressure solenoid valve, and speed regulator disposed within the base, while also facilitating the manufacture of the barrel body, thereby enhancing the convenience of use of the sprayer.

[0011] In the above-mentioned sprayer, a battery accommodating cavity and a cover for closing or opening the battery accommodating cavity are provided on the base, a snap hook is provided on the base, one end of the cover away from the snap hook is hinged to the base, and the other end of the cover has a positioning portion, a buckle is hinged on the positioning portion, a buckle ring is hinged in the middle of the buckle, the buckle ring is sleeved on the hook portion of the buckle hook and locks the buckle hook on the positioning portion, and the buckle ring can be detached from the buckle hook by pulling the buckle. When the battery in the battery accommodating cavity collides with the cover plate, the cover plate drives the buckle hand and the snap ring to rotate synchronously around the hinge between the cover plate and the barrel body. However, since the snap ring is also sleeved on the hook portion of the snap hook, and the snap hook is arranged on the barrel body and will not move with the cover plate, the hook portion of the snap hook can tightly hook the snap ring and hinder the further rotation of the snap ring, so that the cover plate can only be opened by the user by pulling the buckle hand so that the snap ring moves with the buckle hand in a direction away from the positioning portion and disengages from the snap hook, thereby avoiding the cover plate from being accidentally opened due to the battery colliding with the cover plate, thereby improving the reliability of the battery fixation of the sprayer.

[0012] In the aforementioned sprayer, the cover plate is disposed on one side of the base, a control panel is detachably disposed on the other side of the base, and a spray boom mounting portion is disposed on the barrel, with the spray boom mounting portion and the cover plate being located on the same side of the barrel. The detachable control panel on the base allows users to replace the control panel with one that matches the lead-acid or lithium battery being used, thereby improving versatility. Furthermore, the spray boom mounting portion provided on the barrel facilitates vertically securing the spray boom, and positioning the spray boom mounting portion on this side of the cover plate prevents the spray boom, which is located on the spray boom mounting portion, from accidentally contacting switches on the control panel.

[0013] Compared with the existing technology, the advantages of this sprayer are: two strap fixing holes are provided on the handle plate of this sprayer, and two strap fixing parts are provided on the barrel body, which correspond to the strap fixing holes one by one. When in use, the two ends of the single shoulder strap are respectively hung on the two strap fixing holes, and the two ends of the double shoulder strap are respectively hung on the corresponding strap fixing holes and strap fixing parts, so that the user can flexibly choose to set the existing single shoulder strap or double shoulder strap according to the use requirements. At the same time, the handle plate is also provided with a gripping hole, which is convenient for the user to carry the barrel body. In addition, a cushion is provided on the back of the barrel body, and the user's back rests on the cushion when carrying it, thereby improving the convenience and comfort of using the sprayer.
