Detailed implementation manners

[0022] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0023] An inflation assembly for a sprayer, as Figures 1 to 3 shown, includes a liquid storage bucket 1, a suction pipe 5, a manual air pump, and a spray gun 3. The liquid storage bucket 1 is connected to the spray gun 3 through the suction pipe 5.

[0024] A plurality of support strengthening blocks 18 are arranged at the bottom of the liquid storage bucket 1, and the plurality of support strengthening blocks 18 are evenly distributed along the circumferential direction of the liquid storage bucket 1, so as to improve the structural strength of the liquid storage bucket 1 and ensure the stability of the liquid storage bucket 1 when placed.

[0025] A safety valve 4 is arranged on the liquid storage bucket 1. When the internal pressure of the liquid storage bucket 1 exceeds the preset safety value, the safety valve 4 can be opened to release the pressure, thereby preventing the liquid storage bucket 1 from bursting or leaking due to excessive pressure.

[0026] The manual air pump includes a piston cylinder and a piston rod 2. The piston cylinder is arranged in the liquid storage bucket 1, and the piston rod 2 is slidably arranged in the piston cylinder (not shown in the figure). A lever 6 is rotatably arranged on the liquid storage bucket 1. When the lever 6 swings, the lever 6 can drive the piston rod 2 to reciprocate along the piston cylinder through the linkage assembly 7.

[0027] It should be noted that the lever principle is used to reduce the force required during operation, which is more labor-saving during use, thereby effectively reducing the fatigue of the user.

[0028] Specifically, the linkage assembly 7 includes a first connecting rod 71, a second connecting rod 72, and a third connecting rod 73. The first connecting rod 71 is rotatably connected to the piston rod 2. One end of the first connecting rod 71 is rotatably connected to the end of the piston rod 2 through a first rotating shaft 11. Both the first connecting rod 71 and the second connecting rod 72 are rotatably connected to the third connecting rod 73. The other end of the first connecting rod 71 is rotatably connected to one end of the second connecting rod 72 and one end of the third connecting rod 73 through a second rotating shaft 12. The second connecting rod 72 is rotatably connected to the liquid storage barrel 1. The liquid storage barrel 1 is provided with a supporting portion 9, and the supporting portion 9 is integrally provided with the liquid storage barrel 1. The other end of the second connecting rod 72 is rotatably connected to the supporting portion 9 through a third rotating shaft 13. The third connecting rod 73 is rotatably connected to the lever 6. The lever 6 includes a holding portion 61 and a connecting portion 62. The other end of the third connecting rod 73 is rotatably connected to the end of the connecting portion 62 through a fourth rotating shaft 14. The holding portion 61 and the connecting portion 62 cooperate to form an L shape. The connection part between the holding portion 61 and the connecting portion 62 is rotatably arranged on the supporting portion 9 of the liquid storage barrel 1. Specifically, the lever 6 is rotatably connected to the supporting portion 9 through a fifth rotating shaft 20.

[0029] It should be noted that by operating the rotation of the lever 6, the lever 6 drives the third connecting rod 73 to move through the fourth rotating shaft 14. The third connecting rod 73 drives the first connecting rod 71 and the second connecting rod 72 to perform relative rotation through the second rotating shaft 12. The first connecting rod 71 then drives the piston rod 2 through the first rotating shaft 11, so that the piston rod 2 reciprocally slides along the piston cylinder, thereby realizing pressurization into the liquid storage barrel 1.

[0030] A guiding hole 10 for guiding the piston rod 2 is provided on the supporting portion 9. The piston rod 2 is guided through the guiding hole 10, so that the piston rod 2 slides more smoothly.

[0031] A flexible sleeve 8 is sleeved on the holding portion 61. The flexible sleeve 8 is made of a flexible material, thereby providing a soft touch for the user, making the holding more comfortable, thus improving the user experience. Moreover, the flexible sleeve 8 can protect the holding portion 61 from being eroded by the external environment and extend the service life of the holding portion 61.

[0032] The liquid storage barrel 1 is provided with a flared portion 15. The flared portion 15 is in a funnel shape. A plurality of reinforcing strips 19 are provided on the outer side wall of the flared portion 15. The plurality of reinforcing strips 19 are evenly distributed along the circumferential direction of the flared portion 15, thereby enhancing the structural strength of the flared portion 15.

[0033] At least two lifting positioning hooks 16 are provided on the flared portion 15. In this embodiment, preferably two lifting positioning hooks 16 are provided and are arranged oppositely. The lifting positioning hooks 16 are integrally provided with the flared portion 15. The two lifting positioning hooks 16 provided on the flared portion 15 can effectively improve the stability and safety during the lifting operation. Through the cooperation of the two lifting positioning hooks 16, it can be ensured that the sprayer will not shake or shift during the lifting process, thereby reducing the risk of lifting accidents.

[0034] The specific embodiments described herein are merely illustrative of the spirit of the present utility model; those skilled in the technical field to which the present utility model pertains can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.
