Description

Technical Field

[0001] This utility model relates to the field of liquid pressure pump technology, and in particular to a spray pump. Background Technology

[0002] Spray pumps are widely used in daily life, such as for bottled liquid products like kitchen degreasers, shampoos, cosmetics, perfumes, and insect repellents.

[0003] For example, patent CN212732663U discloses a spray gun, which mainly includes a gun body, a cover for housing the gun body inside and improving its appearance, an internally threaded connector for threaded connection with a liquid container, and a suction tube for drawing liquid. The spray gun can be connected to a liquid container of any shape. The cover includes an upper cover and a lower cover; the upper cover and the lower cover are snap-fit ​​connected; and the internally threaded connector is movably connected to the gun body.

[0004] The problem with the above technology is that, since the internal threaded connector is movably connected to the gun body, the user will rotate the internal threaded connector when rotating the gun body, which will cause the internal threaded connector to rotate loosely with the liquid container, making it easy to leak liquid.

[0005] To address these technical problems, a spray pump is proposed. Utility Model Content

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a spray pump that can prevent the screw cap from rotating while the nozzle is being rotated.

[0007] The technical solution adopted by this utility model to solve the problem is: a spray pump, including a gun body, wherein the gun body is provided with a liquid outlet channel and a liquid pressure channel, the liquid pressure channel is connected to the liquid outlet channel, a piston is dynamically sealed in the liquid pressure channel, a trigger is rotatably connected to the gun body, and the trigger is drivenly connected to the piston; a locking cover is inserted into the bottom of the gun body, and a screw cover is also included, the screw cover is connected to the locking cover, and the gun body can rotate relative to the locking cover.

[0008] As a further improvement to the above technical solution, the lower part of the lock cover extends outward with a protruding edge, and a slot is provided on the protruding edge. The bottom of the gun body is inserted into the slot, and the inner end of the lock cover overlaps the top edge of the protruding edge.

[0009] As a further improvement to the above technical solution, a protrusion is provided on the outer side wall of the lock cover, and a groove is provided on the inner side wall of the gun body, with the protrusion engaging with the groove.

[0010] As a further improvement to the above technical solution, a valve seat is inserted at the inlet end of the liquid outlet channel, an inlet pipe is inserted inside the valve seat, the valve seat is connected to the liquid inlet channel and the liquid inlet pipe, and a ball valve is provided inside the valve seat, the ball valve being located between the liquid inlet channel and the liquid inlet pipe.

[0011] As a further improvement to the above technical solution, a sealing ring is provided between the valve seat and the screw cap, and the sealing ring is located below the lock cover.

[0012] As a further improvement to the above technical solution, a connecting member is provided between the piston and the trigger.

[0013] As a further improvement to the above technical solution, the gun body is provided with an elastic element, which abuts against the trigger.

[0014] As a further improvement to the above technical solution, the liquid outlet end of the liquid outlet channel is provided with a nozzle.

[0015] As a further improvement to the above technical solution, a housing is also included, which covers the gun body.

[0016] The beneficial effects of this utility model are: the screw cap is used to screw onto the container. When in use, the liquid in the container can be pumped out by pulling the trigger. When the user rotates the gun body, the gun body can rotate relative to the locking cap and will not drive the screw cap to rotate, thereby preventing the screw cap from being loosely screwed onto the container and preventing leakage.
