## Abstract

A quantitative pressing sprayer includes a clamping plate, a pressing head, and a hand-held screw cap connected with a container. The pressing head penetrates through the hand-held screw cap. The clamping plate is pressed against and arranged on the pressing head. An end of the clamping plate is used as a fixed end that is connected with the hand-held screw cap. Another end of the clamping plate is used as a pressed end. The clamping plate drives the pressing head with the fixed end as a pivot of a lever. The pressed end and the fixed end form a first arm, the pressing head and the fixed end form a second arm, and the first arm is longer than the second arm.

## Claims

### Claim 1

A quantitative pressing sprayer comprising:
a hand-held screw cap connected with a container;
a pressing head penetrating through the hand-held screw cap; and
a clamping plate pressed against and arranged on the pressing head, the clamping plate comprising:
a fixed end connected with the hand-held screw cap; and
a pressed end,
wherein the clamping plate drives the pressing head with the fixed end as a pivot of a lever, and
wherein the pressed end and the fixed end form a first arm, the pressing head and the fixed end form a second arm, and the first arm is longer than the second arm.

### Claim 2 (depends on 1)

The quantitative pressing sprayer of claim 1, wherein the hand-held screw cap is provided with a long-tailed holding portion and an extending direction of the long-tailed holding portion is identical to an extending direction of the pressed end.

### Claim 3 (depends on 1)

The quantitative pressing sprayer of claim 1, wherein the hand-held screw cap is provided with a guiding groove, the pressing head is provided with a guiding protrusion corresponding to the guiding groove, and the pressing head uses the guiding protrusion to move back and forth along the guiding groove.

### Claim 4 (depends on 1)

The quantitative pressing sprayer of claim 1, wherein the hand-held screw cap is provided with a guiding rib, the pressing head is provided with a guiding groove corresponding to the guiding rib, and the pressing head uses the guiding groove to move back and forth along the guiding rib.

### Claim 5 (depends on 1)

The quantitative pressing sprayer of claim 1, further comprising:
a pump, the pump comprising a bottom having an inlet; and
a straw, the straw comprising:
a first end connected with the of the pump; and
a second end, disposed further from the pump than the first end, dipped into a liquid and provided with a curved, portion extending toward a direction that the pressing head sprays.

### Claim 6 (depends on 5)

The quantitative pressing sprayer of claim 5, further comprising a plastic non-return valve arranged at the inlet.

### Claim 7 (depends on 6)

The quantitative pressing sprayer of claim 6, wherein the non-return valve comprises:
an elastic portion;
a valve body having an upper end and a lower end, the lower end of the valve body corresponding to the inlet and being attached to the inlet to separate the pump from a liquid in the container or the lower end of the valve body is separated from the inset to communicate the pump with the liquid in the container; and
an edge portion connected with the valve body, the upper end of the valve body being connected with the edge portion through the elastic portion.

### Claim 8 (depends on 1)

The quantitative pressing sprayer of claim 1, further comprising a fastener detachably connected between the pressed end of the clamping plate and the hand-held screw cap, thereby limiting displacement of the pressed end.

### Claim 9 (depends on 1)

The quantitative pressing sprayer of claim 1, further comprising an elastic member,
wherein the pressing head further comprises:
a nozzle;
a tube; and
an annular groove,
wherein the tube and the nozzle form a liquid channel,
wherein the annular groove and the tube are coaxially arranged,
wherein the annular groove is arranged outside the tube,
wherein the elastic member sleeves an outer wall of the tube,
wherein an end of the elastic member is arranged in the annular groove, and
wherein another end of the elastic member is pressed against the hand-held screw cap.

### Claim 10 (depends on 9)

The quantitative pressing sprayer of claim 9, wherein the elastic member comprises a spring.

### Claim 11 (depends on 1)

A container comprising the quantitative pressing of claim 1.
