Abstract

A water spray gun includes a main body, an operating member and a switch part. The main body includes a handle portion and a tube portion extended from the handle portion and provided with a spray head. A control assembly is enclosed in the main body for control of water outflow and adjustment of the amount of the water outflow. The operating member is pivotally connected to the position where the handle portion meets the tube portion. The switch part is arranged at the operating member and is engaged with the control assembly. The amount of water outflow is controlled by relative movement between the switch part and the operating member.

First claim

What is claimed is:

1. A water spray gun, comprising:
a main body, which includes a handle portion adapted for being held and provided with a connection end, a tube portion extended from the handle portion, and a spray head provided at the tube portion, having a passage enclosed in the main body having a water-inlet portion located at the handle portion and a water-outlet portion extended to the spray head while a control assembly being disposed on a connection between the water-inlet portion and the water-outlet portion for controlling a water outflow and an adjustment of an amount of the water outflow in the passage;
the control assembly including a valve stem, a spring and a positioning portion;
an operating member, configured to be pressed while the handle portion of the main body being held by an user, having a slot and one end pivotally connected to the connection end of the handle portion to be used as a fulcrum shaft for the operating member being pressed or pushed; and
a switch part, which is moveably located close to one end of the operating member and pivotally connected to the handle portion, including a press part having an upper end, a lower end, a fastening portion, at least one hook portion, and a support shaft portion which is extended from a horizontal central line of the press part and pivotally connected to the slot of the operating member, wherein the press part is divided into the upper end and the lower end by the central line and the fastening portion is extended from the support shaft portion while the hook portion formed on a rear end of the fastening portion; and
wherein the positioning portion of the control assembly is arranged close to the connection end of the handle portion of the main body and corresponding to the switch part, wherein at least one tooth portion is disposed on a surface of the positioning portion and used for engagement with the switch part;
wherein the hook portion of the switch part is selectively to be engaged with or released from the tooth portion of the positioning portion through a pushing by a finger of the user against the upper end or the lower end of the press part correspondingly, wherein the press part is able to be selectively moved downward and inward, or moved upward and inward around the support shaft portion, basically like a seesaw composed of the upper end and the lower end supported by the support shaft portion, thereby the switch part controls the water outflow and provides a multi-stage adjustment of the water outflow.

2. The device as claimed in claim 1 , wherein the positioning portion has a first surface and a second surface, wherein the tooth portion is disposed on the first surface of the positioning portion.

3. The device as claimed in claim 2 , wherein the tooth portion is arranged at the second surface of the positioning portion.

4. The device as claimed in claim 1 , wherein the fastening portion is elastic and the hook portion on the rear end of the fastening portion is facing downward.

5. The device as claimed in claim 1 , wherein the hook portion on the rear end of the fastening portion is facing upward.

6. A water spray gun, comprising:
a main body which includes a handle portion having a connection end and a tube portion extending from the handle portion;
a control assembly, adapted for controlling a water outflow enclosed in the main body, including a positioning portion arranged at the connection end of the handle portion and having at least one tooth portion on a surface of the positioning portion;
an operating member having a slot and one end pivotally connected to the connection end of the handle portion to be used as a fulcrum shaft for the operating member being pressed or pushed; and
a switch part, which is movably located close to the end of the operating member, pivotally connected to the handle portion and engaged with the positioning portion correspondingly, including a press part having an upper end, a lower end, a fastening portion, a hook portion and a support shaft portion which is extended from a horizontal central line of the press part and pivotally connected to the slot of the operating member, wherein the press part is divided into an upper end and a lower end by the central line, wherein the fastening portion is an elastic part extending from the support shaft portion while the hook portion is formed on a rear end of the fastening portion, wherein the press part is able to be selectively moved downward and inward, or moved upward and inward around the support shaft portion, basically like a seesaw composed of the upper end and the lower end supported by the support shaft portion, thereby the switch part is capable of controlling the water outflow and provides a multi-stage adjustment of the water outflow.

7. The device as claimed in claim 6 , wherein the positioning portion is arranged close to the connection end of the handle portion and has a first surface and a second surface, wherein the tooth portion is disposed on the first surface of the positioning portion.

8. The device as claimed in claim 7 , wherein the tooth portion is arranged at the second surface of the positioning portion.

9. The device as claimed in claim 6 , wherein the hook portion on the rear end of the fastening portion is facing downward.

10. The device as claimed in claim 6 , wherein the hook portion on the rear end of the fastening portion is facing upward.

11. A water spray gun, comprising:
a main body which includes a handle portion having a connection end and a tube portion extending from the handle portion, wherein a positioning portion is arranged at the connection end of the handle portion and at least one tooth portion is provided on a surface of the positioning portion;
a control assembly for controlling a water outflow enclosed in the main body;
an operating member having a slot and one end pivotally connected to the connection end of the handle portion to be used as a fulcrum shaft for the operating member being selectively pressed or pushed; and
a switch part which is moveably located close to the end of the operating member and pivotally connected to the handle portion and engaged with the positioning portion correspondingly, wherein the switch part includes a press part including a fastening portion, a hook portion and a support shaft portion, wherein the support shaft portion is extended from the press part and pivotally connected to the slot of the operating member, wherein the fastening portion is an elastic part extending from the support shaft portion while the hook portion is formed on a rear end of the fastening portion, wherein the press part is able to be selectively moved downward and inward, or moved upward and inward around the support shaft portion, basically like a seesaw having an upper end and a lower end supported by the support shaft portion, wherein the hook portion of the switch part is able to be selectively engaged with or released from the tooth portion of the positioning portion being selected, thereby the switch part is capable of controlling the water outflow and provides a multi-stage adjustment of the water outflow.

12. The device as claimed in claim 11 , wherein the positioning portion has a first surface and a second surface and the tooth portion is disposed on the first surface of the positioning portion.

13. The device as claimed in claim 12 , wherein the tooth portion is arranged at the second surface of the positioning portion.

14. The device as claimed in claim 11 , wherein the fastening portion is elastic and the hook portion on the rear end of the fastening portion is facing downward.
