DETAILED DESCRIPTION

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings. Figure 1-10 As shown, a downward pressure water injection device for a water dispenser comprises a water dispenser body 1, a valve block 2 is arranged at the top of the water dispenser body 1, a fixed water storage barrel 3 is arranged at the top of the valve block 2, and a dustproof and breathable cover 4 is arranged at the top of the fixed water storage barrel 3; a valve stem 5 is inserted in the valve block 2, a water-passing groove 6 is provided on the valve stem 5, a spring installation groove 9 is provided in the valve block 2 at the right end of the valve stem 5, a spring 10 is provided in the spring installation groove 9, and the spring 10 is sleeved on the valve stem 5, wherein a water inlet hole 7 is provided at the top of the spring installation groove 9, and the water inlet hole 7 is connected to the fixed water storage barrel 3; a water outlet hole 8 is also provided on the valve block 2, and the water outlet hole 8 is connected to the fixed water storage barrel 3 and the water outlet of the water dispenser body 1, wherein the valve stem 5 crosses the water outlet hole 8; the right end of the spring installation groove 9 is connected to a water hose 11 through a water flow hole, and the other end of the water hose 11 is connected to a water hole 19 provided on a piston block 12; the piston block 12 slides It is arranged in the cylinder sleeve 13, and a spring mounting seat 16 is fixed on the inner bottom wall of the cylinder sleeve 13, and a spring second 15 is connected to the spring mounting seat 16, and the other end of the spring second 15 is connected to the bottom end of the piston block 12; a support seat 17 and a fixing column 21 are arranged on the top of the piston block 12, and a water hole 19 and a vent hole 20 are opened on the fixing column 21, wherein one end of the water hole 19 is connected to a water hose 11, and the other end is provided with a one-way valve three 23, wherein one end of the vent hole 20 is connected to the cylinder sleeve 13 below the piston block 12, and the other end is provided with a one-way valve two 22; a silicone sealing block 24 is sleeved on the fixing column 21, and a spring three 25 is connected to the bottom end of the silicone sealing block 24, and the other end of the spring three 25 is fixed to the top end of the piston block 12; a one-way valve one 18 is also arranged on the piston block 12, and the one-way valve one 18 connects the cylinder sleeve 13 below the piston block 12 with the outside air;

[0022] A sealing ring 14 is provided on the right end of the valve stem 5 and the piston block 12;

[0023] The number of the support seats 17 is 4, which are evenly distributed around the fixing column 21;

[0024] The top of the silicone sealing block 24 is an inverted conical cylindrical structure.

[0025] In this embodiment, after the water in the fixed water storage barrel 3 is drunk, the bottled water bucket 26 is placed upside down on the piston block 12. At this time, the water outlet of the bottled water bucket 26 extends into the inverted cone cylinder at the top of the silicone sealing block 24. Under the action of the self-gravity of the bottled water bucket 26 and the elastic force of the spring three 25, the silicone sealing block 24 will deform and wrap the water outlet of the bottled water bucket 26. The silicone sealing block 24 will seal the water outlet of the bottled water bucket 26 with the cooperation of the fixed column 21; when the outer wall of the bottled water bucket 26 contacts the support seat 17, the bottled water bucket 26 will be fixed by the support seat 17, and at this time, the one-way valve two 22 and the one-way valve three 23 set on the fixed column 21 will enter the bottled water bucket 26.

[0026] When the barreled water bucket 26 is placed on the piston block 12, under the action of the weight of the barreled water bucket 26 itself, the barreled water bucket 26 will squeeze the piston block 12, and the piston block 12 will compress the spring 2 15 to move downward. During the movement, the air pressure in the cylinder sleeve 13 will become larger and larger, and the compressed air will enter the barreled water bucket 26 through the vent hole 20 and the one-way valve 22. The compressed air entering the barreled water bucket 26 will squeeze the water in the barreled water bucket 26 through the one-way valve 3 23, the water hole 19, the water hose 11 and the water flow hole into the spring installation groove 9, thereby pushing the valve stem 5 to compress the spring 10 and move to the left. At this time, the valve stem 5 will cut off the water outlet hole 8; then Press the bottled water bucket 26 downward with force, so that the bottled water bucket 26 drives the piston block 12 to continue to compress the spring 2 15 and move downward. At this time, the air pressure in the cylinder sleeve 13 will become larger and larger, and the compressed air will enter the bottled water bucket 26 through the vent hole 20 and the one-way valve 22. The compressed air entering the bottled water bucket 26 will squeeze the water in the bottled water bucket 26 into the spring mounting groove 9 through the one-way valve 3 23, the water hole 19, the water hose 11 and the water flow hole, thereby pushing the valve stem 5 to continue to compress the spring 10 and move to the left. At this time, the right end of the valve stem 5 will move to the left side of the water inlet hole 7, and the water can enter the fixed water storage bucket 3 through the water inlet hole 7. When the bottled water bucket 26 is squeezed hard, under the elastic force of the spring 2 15, the bottled water bucket 26 will return to the position before squeezing. At this time, the air pressure in the cylinder sleeve 13 will decrease, and then the outside air will enter the cylinder sleeve 13 through the one-way valve 18 to replenish the cylinder sleeve. At this time, the bottled water bucket 26 can be squeezed repeatedly, and finally the water in the bottled water bucket 26 will enter the fixed water storage barrel 3.

[0027] When there is no water in the barreled water bucket 26, the barreled water bucket 26 is removed. At this time, under the elastic force of the spring 10, the valve stem 5 returns to its original position, and the water inlet 7 is cut off and the water outlet 8 is connected.

[0028] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the present invention. Some changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the present invention and fall within the protection scope of the present invention.
