Description

TECHNICAL FIELD

[0001] The present application relates to the field of water dispensers, in particular to a water outlet nozzle structure capable of preventing water leakage. BACKGROUND

[0002] The existing water dispensers, instant water dispensers and other devices are provided with a water outlet nozzle on the body. When a user needs to drink water, the user operates the water dispenser or instant water dispenser to generate drinking water, which is discharged through the water outlet nozzle. The user uses a cup to receive the drinking water. When the amount of drinking water received by the user is satisfied, the user can turn off the water dispenser or instant water dispenser at any time.

[0003] However, the existing water dispensers or instant water dispensers have an unreasonable design of the water outlet nozzle, which is prone to water leakage. SUMMARY

[0004] The present application aims to provide a water outlet nozzle structure which is simple in structure, reliable and capable of preventing water leakage.

[0005] The present application is achieved in the following manner:

[0006] A water outlet nozzle structure capable of preventing water leakage comprises a shell, a lever and a piston. The shell is provided with a water inlet and a water outlet. The lever is provided with a fulcrum and is installed in the shell through the fulcrum. The piston is arranged at the end of the lever close to the water outlet. The end of the lever close to the water inlet is provided with a water scoop. The lever rotates around the fulcrum to close or open the water outlet.

[0007] When water is discharged, water enters the shell through the water inlet. Since the flow rate of water entering the water scoop is greater than the water discharge capacity of the water scoop, the water scoop is loaded with water, which causes the weight of the end of the lever close to the water inlet to be greater than the weight of the end of the lever close to the water outlet. The lever rotates towards the water inlet, causing the piston to move away from the water outlet and thus opening the water outlet, thereby achieving water discharge. When the water inlet stops supplying water, the water in the water scoop flows out in the direction of the open end of the water scoop, causing the weight of the end of the lever close to the water inlet to be less than the weight of the end of the lever close to the water outlet. The lever rotates towards the water outlet, causing the piston to insert into the water outlet and thus closing the water outlet, thereby achieving water leakage prevention. The principle is simple and reliable.

[0008] The object of the present application can also be achieved by the following technical measures:

[0009] Further, the end of the lever close to the water outlet is provided with a mounting hole, and the piston is fixed to the mounting hole. By providing the mounting hole, the piston is fixed to the mounting hole, thereby achieving firm fixation of the piston on the lever and preventing the piston from coming loose.

[0010] Further, the piston is a conical piston, and the tip of the piston is directed towards the water outlet. The piston is inserted into the water outlet from the tip, and the conical piston gradually strengthens the sealing effect of the water outlet as the piston is gradually inserted into the water outlet.

[0011] Further, the piston is provided with a sealing structure for secondary sealing of the water outlet. The piston seals the water outlet in a primary sealing manner, and the piston is further provided with a secondary sealing structure to seal the water outlet, thereby greatly improving the sealing effect of the water outlet and the anti-seepage effect of the water outlet nozzle.

[0012] Further, a counterweight is further included, and the counterweight is arranged at the lever end portion close to the water outlet. When the water inlet stops water inflow, the counterweight is arranged at the lever end portion close to the water outlet, the weight of the lever end portion close to the water inlet is increased, the lever is maintained to rotate towards the lever end portion close to the water outlet, and the piston is maintained in a state of sealing the water outlet.

[0013] Further, a limiting structure is arranged at the lever end portion close to the water inlet, and the counterweight is fixed on the limiting structure. By arranging the limiting structure, the counterweight is prevented from being detached or loosened.

[0014] Further, the counterweight is a heavy ball, and a clamping opening is arranged at the lever end portion close to the water inlet, the clamping opening forms the limiting structure, and the heavy ball is clamped in the clamping opening. The counterweight is clamped in the clamping opening, and the counterweight is prevented from being detached or loosened.

[0015] Further, the top of the water bucket and one side wall thereof are open to form the water inlet and the water outlet.

[0016] Further, the bottom of the water bucket is provided with a water outlet, and the diameter of the water outlet is smaller than the size of the water inlet of the water bucket. The diameter of the water outlet is smaller than the size of the water inlet of the water bucket, and the water inflow of the water bucket is greater than the water outflow when the water bucket is filled with water.

[0017] Further, the bottom wall of the shell is a slope, the upper end of the slope is the water inlet, the lower end of the slope is the water outlet, the height of the water inlet is higher than the height of the water outlet, and the drinking water in the inner cavity of the shell is discharged to the water outlet under the action of gravity and the slope.

[0018] The beneficial effects of the present application are as follows:

[0019] The application, when water is discharged, water enters the shell through the water inlet, because the flow of water entering the water bucket is greater than the water discharge capacity of the water bucket, the water bucket is loaded with water, which causes the weight of the lever end near the water inlet to be greater than the weight of the lever end near the water outlet, the lever rotates towards the water inlet, causing the piston to move away from the water outlet, thereby opening the water outlet and achieving water discharge. When the water inlet stops water, the water in the water bucket flows out in the direction of the open mouth of the water bucket, causing the weight of the lever end near the water inlet to be less than the weight of the lever end near the water outlet, the lever rotates towards the water outlet, causing the piston to insert into the water outlet, thereby closing the water outlet and achieving water leakage prevention. The principle is simple and reliable.

[0020] The application, the piston is inserted into the water outlet from the tip, because the piston is a conical piston, the piston gradually strengthens the sealing of the water outlet when it gradually inserts into the water outlet, greatly improving the sealing effect.

[0021] The application, the drain hole diameter is smaller than the inlet size of the water bucket, when the water bucket is filled with water, the water inlet capacity of the water bucket is greater than its water discharge capacity, achieving water loading. BRIEF DESCRIPTION OF DRAWINGS

[0029] The lever 2 is provided with a fulcrum 21 at the center, the lever 2 is installed in the shell 1 through the fulcrum 21, the lever 2 rotates around the fulcrum 21, the end of the lever 2 near the water outlet 12 is provided with a mounting hole 22, and the end of the lever 2 near the water inlet 11 is provided with a water bucket 5.

[0030] The piston 3 is a conical piston, the piston 3 is fixed at the installation port 22, the tip of the piston 3 is towards the water outlet 12.

[0031] The counterweight 4 is a heavy ball, the lever 2 end near the water inlet 11 is provided with a bayonet 23, the bayonet 23 forms the limiting structure, the heavy ball is clamped in the bayonet 23.

[0033] Working principle:

[0034] The drinking water produced by the water dispenser enters the inner cavity of the shell 1 through the water inlet 11, the drinking water continuously enters the inner cavity of the shell 1, part of the drinking water enters the water bucket 5, because the water inlet of the drinking water in the water bucket 5 is greater than the water outlet, the water bucket 5 is always filled with drinking water, which causes the weight of one side of the water bucket 5 to be larger, the weight of the water bucket 5 is greater than the weight of the counterweight 4, the lever 2 rotates towards the water bucket 5, the lever 2 drives the piston 3 to move away from the water outlet 12, thereby opening the water outlet 12, the drinking water in the inner cavity of the shell 1 is discharged to the water outlet 12 under the action of gravity and the inclined surface 13, realizing water drainage.

[0035] When the user stops the water dispenser, the water dispenser does not produce drinking water, at this time the water in the water bucket 5 is discharged along the water outlet 52, the weight of the water bucket 5 is less than the weight of the counterweight 4, the lever 2 rotates towards the counterweight 4, the lever 2 drives the piston 3 to insert into the water outlet 12, thereby blocking the water outlet 12, the residual drinking water in the shell 1 cannot be discharged to the water outlet 12, thereby realizing the water leakage prevention effect of the water outlet.

[0036] Further, the piston 3 is provided with a sealing structure for secondary sealing of the water outlet 12, when the piston 3 blocks the water outlet 12, the sealing structure is tightly attached to the water outlet 12, realizing secondary sealing of the water outlet 12, improving the water leakage prevention effect of the water outlet.
