Description

Technical Field

[0001] The utility model relates to the technical field of drinking water equipment, in particular to a structure for a water supply distributor, and more particularly to a water spray prevention structure for a water supply distributor. Background Art

[0002] A water dispenser is a device that heats or cools bottled purified water (or mineral water) for convenient drinking. The dispenser is used with a bottled water dispenser placed on top. Bottled water dispensers have been around since before the mid-20th century. These dispensers feature a specialized connector on top that allows the water bucket to be placed upside down. The latest international models place the bottled water in the lower portion of the dispenser, where it is drawn in by a pump. This method is safer and more hygienic than conventional dispensers. The barrel size varies depending on the dispenser.

[0003] Prior art (CN101143069B) discloses a water dispenser with no secondary pollution, a matching drinking water bucket, and an operating method thereof. The dispenser is characterized in that a water storage distributor is provided at the base of the dispenser, the inlet of the water storage distributor being directly connected to the bucket mouth, the outlet of the water storage distributor being respectively connected to a direct-heating electric water heater and a cold water shut-off valve, the direct-heating electric water heater being equipped with a direct-heating electric heating element, and the outlet of the direct-heating electric water heater being connected to a hot water shut-off valve. The auxiliary accessory is a non-secondary pollution filling bucket, with an air storage membrane sleeve mounted on the bottom cover of the bucket. When the dispenser shut-off valve is opened, water flows out of the shut-off valve under its own weight. The air inlet hole in the bottom cover of the bucket creates a space for natural air intake, and the air storage membrane sleeve in the bucket body gradually expands, ensuring that the water in the bucket is subjected to a balanced atmospheric pressure, allowing the water to be discharged naturally under its own weight.

[0004] However, in the process of implementing the technical solution in the prior art, the applicant discovered that the technical solution in the prior art had the following technical problems:

[0005] In existing water dispensers, because the water bucket must be inserted upside down into the dispenser's inlet, water spraying is common when a pump is used to assist in dispensing water. Furthermore, water can accumulate in the dispenser connecting the bucket to the dispenser for extended periods of time. This is especially true when the water in the bucket is nearly empty and there's still a long time before the next bucket replacement. This residual water can become trapped in the dispenser for extended periods of time, making it difficult to drain. Utility Model Content

Residual water can be poured out by removing the anti-spray mechanism. This effectively solves the existing technical problem of water dispensers being prone to spraying and difficult to remove, thereby achieving the technical effect of preventing easy spraying and facilitating the removal of residual water.

DETAILED DESCRIPTION

[0030] The following further describes specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the descriptions of these embodiments are intended to aid understanding of the present invention and do not constitute limitations on the present invention. Furthermore, the technical features involved in the various embodiments of the present invention described below may be combined with one another as long as they do not conflict with one another.

[0031] Most of the existing water dispensers insert the drinking water bucket upside down into the dispenser above the water dispenser body. If the drinking water bucket is inserted into the dispenser with excessive force, water spraying may easily occur.

[0032] Furthermore, if the water in the drinking water bucket is almost empty and the water dispenser is not used for an extended period, such as during a long vacation, users often fail to replace the bucket promptly. This can lead to residual water accumulating in the dispenser and even the dispenser for extended periods, which can easily deteriorate. Turning on the water valve to drain the remaining water takes time, and some residual water may still remain. Using a water pump may also prevent the residual water from being completely removed due to air pressure issues. The air pressure may even exert a force on the drinking water bucket during pumping, causing it to deform.

[0033] The technical solution of the embodiment of the present application solves the problem in the prior art that water dispensers are easy to spray water but difficult to clear residual water by providing a water spray prevention structure for the water supply dispenser. The float 111 is combined with a silicone plug (spring plug 210 / spring silicone plug / ) and an air supply hole to achieve the beneficial effects of avoiding easy water spraying and facilitating the removal of residual water.

[0034] The overall idea of ​​the implementation scheme of the present invention to solve the above technical problems is as follows:

[0035] A water spray prevention structure for a water supply dispenser comprises a water inlet 100, a water outlet 200, and a steam supply hole 300. The water inlet 100 is connected to the bottle mouth 410 of the water supply source 400. The water inlet 100 is provided with a rim cavity 120 and a float chamber 110 located in the center of the water inlet 100. A float 111 is placed within the float chamber 110. The periphery of the float chamber 110 is connected to and extends through the rim cavity 120, which is in communication with the steam supply hole 300. A silicone gasket 500 is provided at the end of the float chamber 111 away from the water supply source 400. The end of the silicone gasket 500 away from the float 111 is the water outlet 200, which is equipped with a spring plug 210 and a water outlet 220. The float 111 and the spring plug 210 respectively block the ends of the hole in the silicone gasket 500. The two ends close to the hole of the silicone gasket 500 are the positions of the spring plug A and the float B respectively, and the positions close to the water supply source 400 and the water outlet 220 are the positions of the float A and the spring plug B respectively.

[0036] When the water supply distributor's anti-spray structure is connected to an electrical appliance and a water source 400 at both ends, and the appliance's water pump is not activated, water from the water source 400 enters the float chamber 110 through the edge cavity 120 of the water inlet end 100. Under the buoyancy of the water, the float 111 rises from position B to position A, and water flows from around the float chamber 110 to the hole in the silicone gasket 500. At this point, due to the spring's upward force, the hole in the silicone gasket 500 remains held in place by the spring plug 210, which is in position A. This prevents water from entering the water outlet end 200 and instead flows through the water outlet 220 into the electrical appliance.

[0037] When the water pump of the appliance is started, the silicone plug (spring plug 210) is pulled down to the spring plug B position under the action of suction, leaving the hole of the silicone gasket 500 unobstructed. At this time, the water that has entered the float chamber 110 from the water supply source 400 enters the water outlet 200 through the hole of the silicone gasket 500, and flows around the spherical surface 211 of the spring plug 210 to the water outlet 220 and into the appliance.

[0038] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0039] A water spray prevention structure for a water supply distributor, such as Figure 1 and Figure 2 As shown, it consists of a water inlet end 100, a water outlet end 200 and a steam supply hole 300: a silicone gasket 500 is installed between the water inlet end 100 and the water outlet end 200, the water inlet end 100 consists of a float chamber 110 located in its center and an edge cavity 120 located around the float chamber 110, and the water inlet end 100 is connected to the steam supply hole 300.

[0040] The water inlet 100 is connected to the bottle mouth 410 of the water supply source 400, and the water outlet 200 is connected to an electrical appliance (a water dispenser-type appliance including a water pump). The inner wall of the rim cavity 120 of the water inlet 100 is provided with internal threads 121, and the bottle mouth 410 of the water supply source 400 is provided with external threads 411. Through the internal threads 121 of the water inlet 100 and the external threads 411 of the bottle mouth 410 of the water supply source 400, the water spray prevention structure is tightly coupled to the water supply source 400.

[0041] The float chamber 110 is provided with a float 111. When there is no water, the float 111 sits on the silicone gasket 500 and blocks the gasket hole 510 of the silicone gasket 500. The float 111 is preferably a PP float.

[0042] The water outlet 200 is provided with a water outlet 220 and a spring plug 210. A spring is provided at the bottom of the spring plug 210. When the water supply distributor is not connected to an electrical product with a water spray prevention structure and the water pump is started, the spring plug 210 presses against the gasket hole 510 of the silicone gasket 500 through its spherical surface 211 under the force of the spring. Figure 3 shown.

[0043] At this time, both sides of the gasket hole 510 of the silicone gasket 500 are blocked by the float 111 and the spring plug 210 respectively.

[0044] The two ends close to the hole of the silicone gasket 500 are the positions of the spring plug A and the float B respectively, and the positions close to the water supply source 400 and the water outlet 220 are the positions of the float A and the spring plug B respectively.

[0045] During use, first securely connect the edge cavity 120 of the water inlet 100 to the bottle mouth 410 of the water supply source 400. Then, invert the device and connect it to the electrical appliance. Water then flows into the float chamber 110, and the buoyancy of the water causes the float 111 to rise from position B to position A. The water remains blocked outside the water outlet 200 by the spring plug 210. The appliance's water pump is then activated, and suction forces the spring plug 210 downward to position B. Water then flows through the gasket hole 510 of the silicone gasket 500, into the water outlet 200, and into the electrical appliance through the water outlet 220.

[0046] The function of the water spray prevention structure for the water supply distributor of the present utility model is described as follows:

[0047] 1. Screw the main body of the water supply distributor with anti-spray structure into the water supply bottle, and insert the water outlet end 200 of the water supply distributor with anti-spray structure upside down into the corresponding hole of the electrical product with pumping function;

[0048] 2. When the water supply bottle is inverted, water flows into the PP float chamber 110 under the force of gravity. The float 111 rises from its original position B to position A under the action of buoyancy. When the electrical product is not started and the water pump is not working, the rubber plug spring always presses against the silicone plug to block the holes of the silicone gasket 500.

[0049] 3. Start the electrical appliance and the water pump. The silicone plug is pulled down to position B by suction. At this time, the water in the float chamber 110 flows through the silicone plug spherical surface 211 from all sides to the water outlet 220 until the water in the water supply bottle is completely pumped out.

[0050] 4. When the water cup in the water supply bottle is completely drained, the PP float 111 sinks to position B and fits into the middle hole of the silicone gasket 500. At this time, if the electrical product is turned on and the water pump starts working, the suction generated by the water pump will pull the silicone plug down again. At the same time, the suction acts on the PP float 111, making the float 111 fit more closely to the silicone gasket 500. The water remaining in the machine pipe cannot be pumped out by the water pump, which plays a safety role in preventing water spray.

[0051] Furthermore, the water supply source 400 is preferably 2L bottled water.

[0052] Furthermore, the spring plug 210 is preferably a silicone spring plug 210 , which is covered in the water outlet 220 of the water outlet end 200 by a spring fixing cover 213 .

[0053] Furthermore, in order to prevent the float 111 from floating up without limit, a float cover 113 is installed on the top of the float chamber 110 to limit the float 111 in the float chamber 110 .

[0054] Furthermore, the steam supply hole 300 is connected to the atmosphere and the water inlet end 100 through a 90-degree turn air passage.

[0055] Furthermore, in order to prevent water from leaking from the steam supply hole 300, a silicone cover 310 is provided on the steam supply hole 300 and an air-inlet water-blocking silicone 320 is installed. The steam supply hole 300 is connected to the atmosphere and the edge cavity 120 of the water inlet end 100 and is connected to the float chamber 110. The air-inlet water-blocking silicone 320 only allows gas to pass through the steam supply hole 300 from the atmosphere into the float chamber 110 in one direction, and does not allow water to flow out of the steam supply hole 300 into the atmosphere in the opposite direction.

[0056] In order to further improve the anti-blowout effect and optimize the anti-blowout effect, such as Figure 4-7 As shown, a water spray prevention structure is installed at the water inlet 810 of the electrical product, and the water spray prevention structure is fixed in the water inlet structure installation device 800 of the water inlet 810. The water inlet structure installation device 800 does not have a water spray prevention function, but after the water spray prevention structure is installed, it can play a role in preventing water spray.

[0057] The electrical appliance includes a water outlet arm 600, a water outlet structure 700 mounted on the water outlet arm 600, and a water inlet structure mounting device 800. The water outlet arm 600 is movably connected to the main body of the appliance and is covered by a water outlet arm cover 610. The water inlet structure mounting device 800 is located at the end of the main body away from the water outlet arm 600. The water supply distributor is installed in the water inlet structure with a water spray prevention structure. A water pump delivers water along the pipe built into the water outlet arm 600 to the water outlet structure 700. The water outlet structure 700 includes a water inlet end 750 and a water outlet 730. The water inlet end is connected to a hose.

[0058] The water outlet structure 700 may be a water spray-proof water outlet structure 700 or a non-water spray-proof water outlet structure 700, and the water spray-proof water outlet structure 700 is preferred.

[0059] When the anti-spray water outlet structure 700 is selected, a front water vapor pressure relief chamber 710 is provided in the water outlet structure 700, and a plurality of pressure relief structural pieces 711 are provided in the front water vapor pressure relief chamber 710 to reduce the water vapor flow rate and pressure. The front water vapor pressure relief chamber 710 is covered by a pressure relief chamber cover 720, and the water outlet 730 is provided with a water collector 740; the water outlet arm 600 is covered by a water outlet arm cover 610.

[0060] When water enters the front water vapor plenum chamber 710, the water vapor flow rate and pressure are buffered and weakened by the special plenum structural piece 711 in the front water vapor plenum chamber 710 to achieve a safety and water spray prevention effect.

[0061] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
