The present disclosure relates to the technical field of liquid sprayers, and more particularly to a multifunctional spray gun. The spray gun comprises a handle designed for single-hand four-finger ergonomic gripping and a pressing plate configured for single-hand thumb depression. The handle and the pressing plate are hingedly connected to enable more labor-saving and convenient single-handed operation. Additionally, a spray nozzle is detachably connected to the spray gun's discharge end to atomize liquid for spraying applications. Simultaneously, a foam spray head is detachably connected to the spray nozzle, converting atomized liquid from the spray nozzle into foam to achieve foam discharge requirements. When foam functionality is unnecessary, the foam spray head can be removed. Further, when atomization is unnecessary, the spray nozzle can be detached to discharge liquid only. The above design satisfies diverse liquid-discharging requirements across different scenarios, providing multifunctionality and convenient operation.

A perfume bottle including a head with an atomising nozzle oriented upwards at a specific angle with respect to the longitudinal axis of the bottle and a regulating mechanism by means of which it can deliver sprays at partial percentages. It can have a manual application or form a system with the bottle located at a base to have an electromechanical application from the base, both of the individual bottle and of a set of bottles located at the same base in a circular configuration, so as to obtain a specific mixture of perfumes applied to a user or in a refill bottle.

A discharge head for dispensing liquids and for attachment to a liquid reservoir. The discharge head has a discharge head base with a coupling device for connecting to the liquid reservoir, a discharge opening and a pump device for conveying liquid from the liquid reservoir to the discharge opening. The pump device has a pump cylinder and a pump piston guided in a sealing manner along a cylinder sliding surface. The pump piston is fixed relative to the discharge head base, and the pump cylinder is formed by a cylinder component movable relative to the discharge head base. A return spring, configured as a plastic bellows spring exerts a counteracting return force on the cylinder component when moved in an actuating direction relative to the pump piston.
