Specific implementation

[0019] The technical scheme of the present application will be further explained and described by specific implementation.

[0020] Referring to the drawings, the utility model provides a kind of pump body for toy water gun, including spring seat 1, spring, piston 6, pump body shell 2, sealing bowl 3, water spraying cap 4;

[0021] The spring seat 1 includes seat body 13, and limiting column is formed on the seat body 13;Connecting wall is extended on the both sides of limiting column, and clamping interface 14 is opened on connecting wall;Spring one 5 is sleeved on limiting column, and piston 6 is installed in contact with spring one 5;Limiting column also has the effect of limiting piston 6;The diameter of piston 6 is less than spring one 5, so that it can improve higher water pressure, and sealing ring 15 is sleeved on piston 6;Pump body shell 2 is clamped on the protrusion of spring seat 1 in clamping interface 14, and pump body shell 2 is sleeved outside piston 6;Connecting plate 7 is arranged in pump body shell 2, and base is connected on connecting plate 7, and installation cavity one 8 is protruded on base, and installation cavity one 8 also has the effect of limiting sealing bowl 3, and installation cavity two 9 is formed outside installation cavity one 8, and notch is formed in the upper end of installation cavity two 9, to facilitate the installation of sealing bowl 3;Spring two 10 is installed in installation cavity one 8, and sealing bowl 3 is installed in installation cavity two 9 outside the side of spring two 10, and water spraying cap 4 is installed on pump body shell 2 outside installation cavity two 9, and water outlet pipe 11 is connected on water spraying cap 4, and water outlet pipe 11 is connected with sealing bowl 3 in contact;

[0022] The pump body shell 2 is connected with inlet and return water pipe 12, and inlet and return water pipe 12 communicates installation cavity two 9.

[0023] In use, the toy water gun pump body is connected to the water gun, the inlet and outlet pipe 12 is connected to the water gun water path, the water flow enters the installation cavity two 9, the water flow is pressurized, the water flow flows out of the edge of the sealing bowl 3, the sealing bowl 3 contacts the water cap 4, so the water flow cannot flow out of the water cap 4; then the water flows into the piston 6 position through the gap of the connecting plate 7, the water pressure compresses the spring one 5, and high-pressure water is formed. At this time, the installation cavity one 8 and the installation cavity two 9 have the same water pressure, when the water gun trigger is pulled, the water pressure of the installation cavity two 9 is released, low-pressure water is formed, the high-pressure water of the installation cavity one 8 pushes the sealing bowl 3, the low-pressure water is discharged from the inlet and outlet pipe 11, at the same time, the sealing bowl 3 is separated from the water cap 4, the high-pressure water of the installation cavity one 8 is sprayed from the outlet pipe 11 of the water cap 4; a water shooting is completed.

[0024] The limiting column limits the piston 6, can control the water injection amount, prevent the piston 6 from being separated from the pump body shell 2 due to too large water amount, and protect the fatigue resistance of the spring one 5, so as to increase the durability; the installation cavity one 8 limits the travel of the sealing bowl 3, prevents the sealing bowl 3 from being too large, blocks the inlet and outlet pipe 11, and also causes too much water to flow out of the water cap 4 when the sealing bowl 3 returns; because the high-pressure water is released, the internal water is in a pressureless state, the sealing bowl 3 returns and pushes the pressureless water to flow out of the water cap 4.
