Description

Technical Field

[0001] The utility model relates to a multi-cavity sprayer. Background Art

[0002] An electric sprayer is a device driven by electric power to spray liquid quickly and effectively. It usually consists of an electric pump and a nozzle, which can increase the pressure of the liquid and spray the liquid (such as paint, pesticides, detergents, etc.) evenly onto the target surface. This equipment is widely used in the construction, agriculture and cleaning industries because it can improve work efficiency and ensure uniformity of application.

DETAILED DESCRIPTION

[0023] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "page", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0024] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0025] In the description of the present utility model, "multiple" means two or more than two, unless otherwise clearly specified and specifically defined. In the present utility model, unless otherwise clearly specified and defined, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal connection of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0026] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0027] like Figure 1 , Figure 2 As shown, a multi-chamber sprayer includes a housing 1. A liquid outlet chamber 2 is provided at the bottom of the housing 1. A liquid outlet 3 is provided at the bottom of the liquid outlet chamber 2. The liquid outlet 3 can be connected to a corresponding water pipe and a nozzle, and driven by an electric pump to deliver liquid, which is a prior art and will not be described in detail.

[0028] In order to solve the purpose of convenient switching of multiple cavities, such as Figure 3 As shown, the housing 1 is provided with a plurality of chambers 4 around the top of the liquid outlet chamber 2. This application takes three chambers 4 as an example. Figure 4 As shown, a liquid inlet pipe 5 is provided at the top of the chamber 4. When it is necessary to add liquid medicine to each chamber 4, liquid can be added through the liquid inlet pipe 5 so that the liquid enters the chamber 4 for storage.

[0029] A gear 6 is arranged around the outer edge of one side of the top of the chamber 4 and is provided through a bearing. Correspondingly, the gear 6 is meshed with a gear ring 7. The gear ring 7 is fixedly connected to the housing 1. A driving wheel 8 is meshed together in the middle of the three gears 6. A driving shaft 9 is connected to the top of the driving wheel 8. A fixing seat 10 is fixedly arranged between the driving shaft 9 and the housing 1. The driving shaft 9 is connected to a handle 11 through the fixing seat 10. When the handle 11 is rotated, it can drive the driving shaft 9 to rotate, thereby driving the driving wheel 8 to rotate. The rotation of the driving wheel 8 drives the gear 6 to rotate and move around the gear ring 7. Since a bearing is arranged between the gear 6 and the chamber 4, the chamber 4 will not rotate, but will move as the gear 6 moves around.

[0030] Optimally, the middle of the gear 6 is fixedly connected to the liquid inlet pipe 5, the liquid inlet pipe 5 penetrates into the chamber 4 and is provided with a stirring blade 12 in the chamber 4. When the gear 6 rotates, the stirring blade 12 can rotate, thereby stirring and mixing the liquid medicine in the chamber 4 evenly.

[0031] like Figure 5 As shown, correspondingly, a liquid inlet 13 is provided on one side of the liquid outlet chamber 2, and a mounting seat 14 is provided at the bottom of the liquid inlet 13. A connecting pipe 15 is passed through the fixing seat 10. A positioning spring 16 is provided between the connecting pipe 15 and the fixing seat 10.

[0032] like Figure 6 As shown, correspondingly, a through hole 17 is provided at the bottom of each chamber 4. The through hole 17 is provided corresponding to the connecting tube 15. A plunger 18 is provided in the through hole 17. The plunger 18 is hinged with a connecting seat 19. A return spring 20 is provided at the hinge between the connecting seat 19 and the plunger 18. In the initial state, the plunger 18 covers the through hole 17, so that the through hole 17 is closed, and the liquid medicine in the chamber 4 will not leak from the chamber 4. When the gear 6 rotates to drive the chamber 4 to move around to the position of the connecting tube 15, the connecting tube 15 pushes the plunger 18 to rotate inward under the action of the positioning spring 16, so that the connecting tube 15 is connected with the chamber 4. The liquid medicine in the chamber 4 enters the liquid outlet chamber 2 along the connecting tube for spraying the liquid medicine.

[0033] Under the above arrangement, the handle 11 at the top can be rotated to drive each chamber 4 to move simultaneously, so that multiple chambers 4 can be conveniently switched. Moreover, more chambers 4 can be arranged and adjusted according to actual needs.

[0034] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
