[0002] In the field of cosmetics, bottle bodies with pump heads are often used to store liquids, such as bottle bodies with emulsion pumps. When needed, the emulsion pump head is pressed to take out the required emulsion, which is convenient and sanitary.

[0003] However, the traditional cosmetic containers on the market have a too far distance of emulsion spraying when customers purchase and use them, resulting in poor customer experience. In addition, the traditional cosmetic containers cannot guarantee that the emulsion in the cosmetic container does not come into contact with air. Once the user opens and uses it, the emulsion remaining at the liquid outlet will be exposed to air and dehydrated, and the effective components in the emulsion in the bottle are also easily oxidized by air.

[0007] Further, the valve needle liquid outlet hole is an integral through type liquid outlet hole.

[0008] Further, the nozzle sealing part is annular.

[0009] Further, the elastic mechanism comprises a first return spring, one end of the first return spring abuts against the nozzle, and the other end is fixed on the inner head, and the first return spring always has a spring force towards the valve needle direction to the nozzle.

[0010] Further, a second return spring is arranged between the valve needle and the inner press head, one end of the second return spring abutting against the valve needle and the other end abutting against a rear cover fixed inside the inner press head.

[0011] Further, a first fluid passage is arranged in the connector and is in through connection with a containing space arranged in the connector; a second fluid passage is arranged at an upper end of the connector and the containing space is in through connection with the second fluid passage.

[0012] The controllable press-type emulsion pump has the advantages that: the controllable press-type emulsion pump is simple in structure, convenient to use, and adjustable in spraying distance; the nozzle sealing part for sealing the emulsion in the fluid passage is arranged on the nozzle; the valve needle liquid outlet hole is arranged at the end of the valve needle head part; the connector is pressed to make the emulsion enter the fluid passage and push the nozzle to move to one side, the valve needle liquid outlet hole is opened, the emulsion is sprayed from the gap between the valve needle and the nozzle through the valve needle liquid outlet hole instead of being directly sprayed along the valve needle axis from the valve needle head part, so that the emulsion spraying distance is adjustable, and the customer's use satisfaction is indirectly improved; after use, the nozzle is restored to the initial position by the elastic force of the elastic mechanism, the emulsion remaining in the gap between the valve needle and the nozzle is automatically sealed, and oxidation caused by air contact is avoided.
