AI Technical Summary
Traditional cosmetic pump heads lack sealing function, causing cosmetics to be trapped in the channel and dried or oxidized, resulting in waste.
A sealed pump head is designed, which adopts an elastic nozzle and a slit structure. The nozzle expands to spray materials when in use and automatically resets and seals after use to prevent air from entering the channel.
It effectively prevents the cosmetics retained in the pump head from drying out or oxidation, thereby improving the utilization rate of the materials.

[0005] Further, the outer tube wall of the tubular insert has a clamping tooth, and the tubular insert is clamped in the plug hole through the clamping tooth.
[0006] Further, the slit is in the shape of a straight line or a cross.
[0007] Beneficial effects: the utility model discloses a kind of sealing pump press head, there is elastic nozzle on pump press head, there is slit on nozzle, when using pump press head, material is extruded slit and is expanded state after being sprayed, after use, slit can be reset closed under the action of elastic force, play good sealing effect, so that the material retained in pump press head is not easy to be dried by wind or oxidized. BRIEF DESCRIPTION OF DRAWINGS
[0008] BRIEF DESCRIPTION OF DRAWINGS Fig. 1 It is the overall structure schematic diagram of pump press head;
[0009] BRIEF DESCRIPTION OF DRAWINGS Fig. 2 It is the internal structure schematic diagram of pump press head. DETAILED DESCRIPTION
[0010] The utility model will be further described below in connection with the drawings.
[0011] As shown in the utility model in figure Figs. 1-2 A kind of sealing pump press head, including pressure cap 1, there is the nozzle 3 on the output port of spray material passage 2, and there is slit 4 on nozzle 3.Nozzle 3 is elastic material, so that slit 4 can be elastically deformed, and can be switched between closed state and expanded state.When slit 4 is closed state, nozzle 3 corresponds to the output port of spray material passage 2 is blocked, material retained in spray material passage 2 is separated from the outside at this time, not easy to be dried by wind or oxidized.And when pressing pump press head, positive pressure will be generated in spray material passage 2, slit 4 is extruded and expanded state, then it is sprayed from slit 4.
[0012] The convex portion is provided on the pressure cap 1, and the output port of the spray material passage 2 corresponds to the convex portion.Nozzle 3 is half-enclosed, and nozzle 3 corresponds to the convex portion, so that nozzle 3 can block the output port of the spray material passage 2 when slit 4 is closed.
[0013] The convex portion has a ring-shaped clamping groove 5 around the outer periphery, and nozzle 3 is correspondingly installed on the ring-shaped clamping groove 5, that is, the edge of nozzle 3 is correspondingly inserted into the ring-shaped clamping groove 5, so as to fix and install nozzle 3 on the pump press head.
[0014] The pressure cap 1 is provided with a insertion hole 6, and the insertion hole 6 has a tubular insert 7, the length of the tubular insert 7 is greater than the depth of the insertion hole 6, so that the outer end of the tubular insert 7 can protrude from the insertion hole 6, thereby forming the convex portion. The inside of the tubular insert 7 is part of the spray material passage 2, and the outer end of the tubular insert 7 is correspondingly the output port of the spray material passage 2.
[0015] The outer end of the tubular insert 7 has a ring of stepped grooves, and the nozzle 3 is correspondingly covered on the stepped grooves of the outer end of the tubular insert 7; after the tubular insert 7 is inserted into the insertion hole 6, the stepped grooves are combined with the inner hole wall of the insertion hole 6 to form the annular clamping groove 5. The nozzle 3 can be inserted into the insertion hole 6 together with the tubular insert 7, so that the nozzle 3 is installed on the annular clamping groove 5. The outer tube wall of the tubular insert 7 has clamping teeth, and the tubular insert 7 is clamped in the insertion hole 6 through the clamping teeth, so that the tubular insert 7 and the nozzle 3 can be stably installed on the pressure cap 1.
[0016] The slit 4 is in the shape of a line or a cross, and the slit 4 on the nozzle 3 is oppositely arranged with the output port of the material spraying channel 2.
[0017] In an embodiment, the pump press head of the utility model is applied to cosmetics, and the material of the nozzle 3 is TPE soft glue. When the cosmetics need to be used, the pressure cap 1 is first pressed, so that the cosmetic material enters the material spraying channel 2, and then the press head is continuously pressed, the material spraying channel 2 is filled with the material, so that the slit 4 at the nozzle 3 is expanded and enlarged under the action of the positive pressure, and the material flows out of the slit 4 for use. When the product use is finished, the press head is released, and the material no longer continuously enters the material spraying channel 2, so that the positive pressure in the material spraying channel 2 is reduced. Since the material of the nozzle 3 is TPE elastic soft glue, the slit 4 is automatically reset and closed under the action of the elastic force, so that air is prevented from entering the material spraying channel 2, and the material in the material spraying channel 2 is protected.
[0018] The above only describes the preferred embodiments of the utility model, and it should be pointed out that: for ordinary skilled persons in the technical field, some improvements and decorations can be made without departing from the principle of the utility model, and these improvements and decorations should also be regarded as the protection range of the utility model.
