Description

Technical Field

[0001] This utility model relates to water dispensers, and more particularly to a heating steam self-circulation absorption device and a water dispenser. Background Technology

[0002] Currently, the venting function is a key part of the normal operation of vehicle-mounted water dispensers. It is mainly used to release the steam or internal air generated during heating in the heating tank to prevent excessive pressure from affecting safety.

[0003] However, since the water dispenser is installed in the driver's cab, directly venting the exhaust into the cab would cause inconvenience to the user. If the exhaust is led out of the vehicle, the exhaust pipe is too long, which is not conducive to rapid exhaust. At the same time, dust can easily accumulate at the exhaust pipe port and block the exhaust outlet, which would also cause poor exhaust. Utility Model Content

[0004] The purpose of this invention is to provide a heating steam self-circulation absorption device and a water dispenser, which aims to solve the problems of existing water dispensers causing problems in the driver's cab or poor exhaust.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: A self-circulating absorption device for heating steam is provided, applied to a water dispenser, comprising: a heating tank, a water tank, an exhaust pipe, an air inlet pipe, a three-way valve, and a duckbill one-way valve. The heating tank is provided with an exhaust port; the water tank is provided with an air inlet; one end of the exhaust pipe is connected to the exhaust port; one end of the air inlet pipe is connected to the air inlet; the three-way valve includes a first interface, a second interface, and a third interface, the first interface being connected to the other end of the exhaust pipe, the second interface being connected to the other end of the air inlet pipe; one end of the duckbill one-way valve is connected to the third interface; wherein, when the internal air pressure of the heating tank and the water tank is lower than a preset air pressure, the duckbill one-way valve opens, and when the internal air pressure of the heating tank and the water tank is not lower than the preset air pressure, the duckbill one-way valve closes.

[0006] Furthermore, the exhaust pipe is a silicone exhaust pipe.

[0007] Furthermore, the air intake pipe is a silicone air intake pipe.

[0008] Furthermore, the tee is a food-grade plastic tee.

[0009] Furthermore, the duckbill check valve is a silicone duckbill check valve.

[0010] Furthermore, the heating steam self-circulation absorption device also includes an air duct connected to the other end of the duckbill check valve.

[0011] This utility model also provides a water dispenser, including a water dispenser body and a heating steam self-circulation absorption device as described above, wherein the heating steam self-circulation absorption device is connected to the water dispenser body.

[0012] Furthermore, the water dispenser also includes a water dispenser panel, which is connected to the water dispenser body.

[0013] Furthermore, the water dispenser also includes a heat preservation device, which is sleeved on the outside of the heating tank.

[0014] Furthermore, the water dispenser also includes a pull-out water outlet device, which is connected to and communicates with the water tank.

[0015] This utility model provides a self-circulating steam absorption device for a water dispenser, comprising: a heating tank, a water tank, an exhaust pipe, an air inlet pipe, a tee, and a duckbill one-way valve. The heating tank has an exhaust port; the water tank has an air inlet; one end of the exhaust pipe is connected to the exhaust port; one end of the air inlet pipe is connected to the air inlet; the tee includes a first interface, a second interface, and a third interface, the first interface being connected to the other end of the exhaust pipe, and the second interface being connected to the other end of the air inlet pipe; one end of the duckbill one-way valve is connected to the third interface; wherein, when the internal air pressure of the heating tank and the water tank is lower than a preset air pressure, the duckbill one-way valve opens; when the internal air pressure of the heating tank and the water tank is not lower than the preset air pressure, the duckbill one-way valve closes. This invention connects the heating tank and the water tank via an exhaust pipe, a T-junction, and an intake pipe. Due to the lower temperature inside the water tank, the high-temperature steam generated by the heating tank condenses into liquid upon reaching the water tank, thereby reducing the air pressure inside the heating tank. When excessive liquid is consumed in the heating tank, the internal air pressure of the heating tank and the water tank gradually decreases. If the internal air pressure of the heating tank and the water tank falls below atmospheric pressure, there is a risk of them collapsing. A duckbill one-way valve opens when the internal air pressure of the heating tank and the water tank falls below a preset pressure to balance the internal air pressure of the heating tank and the water tank with atmospheric pressure, thus protecting the heating tank and the water tank. The entire device achieves self-circulation and absorption of heating steam, solving the problem of existing water dispensers causing inconvenience to the driver's cab or poor exhaust.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0022] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0023] Combination Figure 1-2As shown, this utility model provides a self-circulating steam absorption device 9 for use in a water dispenser, comprising: a heating tank 1, a water tank 2, an exhaust pipe 3, an air inlet pipe 4, a three-way valve 5, and a duckbill one-way valve 6. The heating tank 1 is provided with an exhaust port 11; the water tank 2 is provided with an air inlet 21; one end of the exhaust pipe 3 is connected to the exhaust port 11; one end of the air inlet pipe 4 is connected to the air inlet 21; the three-way valve 5 includes a first interface 51, a second interface 52, and a third interface 53, the first interface 51 is connected to the other end of the exhaust pipe 3, the second interface 52 is connected to the other end of the air inlet pipe 4; one end of the duckbill one-way valve 6 is connected to the third interface 53; wherein, when the internal air pressure of the heating tank 1 and the water tank 2 is lower than the preset air pressure, the duckbill one-way valve 6 opens, and when the internal air pressure of the heating tank 1 and the water tank 2 is not lower than the preset air pressure, the duckbill one-way valve 6 closes.

[0024] In this embodiment of the invention, firstly, the heating tank 1 and the water tank 2 are connected via the exhaust pipe 3, the tee 5, and the air inlet pipe 4. Because the temperature inside the water tank 2 is lower, the high-temperature steam generated by the heating tank 1 condenses into liquid upon reaching the water tank 2, thereby reducing the air pressure inside the heating tank 1. Secondly, when excessive liquid is consumed from the heating tank 1, the internal air pressure of the heating tank 1 and the water tank 2 gradually decreases. If the internal air pressure of the heating tank 1 and the water tank 2 falls below atmospheric pressure, there is a risk of them collapsing. The duckbill one-way valve 6 opens when the internal air pressure of the heating tank 1 and the water tank 2 falls below a preset pressure, allowing air to enter the heating tank 1 and the water tank 2 through the duckbill one-way valve 6, thus balancing the internal air pressure of the heating tank 1 and the water tank 2 with atmospheric pressure, thereby protecting the heating tank 1 and the water tank 2. The heating steam self-circulation absorption device as a whole achieves the self-circulation absorption of heating steam, solving the problem of existing water dispensers' exhaust causing inconvenience to the driver's cab or poor exhaust performance.

[0025] It is understandable that water tank 2 has two states: with water and without water. When there is water in water tank 2, the water in water tank 2 is at room temperature. When the high temperature steam generated by heating tank 1 reaches water tank 2, heat transfer occurs and the steam condenses into liquid, thereby reducing the gas pressure inside heating tank 1. When there is no water in water tank 2, since the capacity of water tank 2 is much larger than that of heating tank 1, it is sufficient to hold a large amount of water vapor, thereby ensuring that the gas pressure inside heating tank 1 will not be too high.

[0026] It is understandable that the exhaust port 11, air inlet 21, exhaust pipe 3 and air inlet pipe 4 are not defined by their names. That is, the exhaust port 11 and exhaust pipe 3 do not restrict the gas from entering the heating tank through the exhaust port 11 and exhaust pipe 3, and the air inlet 21 and air inlet pipe 4 do not restrict the gas from exiting the water tank 2 through the air inlet 21 and air inlet pipe 4.

[0027] In some embodiments, the exhaust pipe 3 is a silicone exhaust pipe 3.

[0028] In this embodiment, the exhaust pipe 3 needs to come into contact with the water vapor generated by the heating tank 1. The water vapor condenses into liquid in the water tank 2 and is recycled. The exhaust pipe 3, made of silicone material, is non-toxic and harmless, thus protecting the health of the drinker.

[0029] In some embodiments, the air intake pipe 4 is a silicone air intake pipe 4.

[0030] In this embodiment, the air inlet pipe 4 needs to come into contact with the water vapor generated by the heating tank 1. The water vapor condenses into liquid in the water tank 2 and is recycled. The air inlet pipe 4, made of silicone material, is non-toxic and harmless, thus protecting the health of the drinker.

[0031] In some embodiments, the tee 5 is a food-grade plastic tee 5.

[0032] In this embodiment, food-grade plastic refers to plastic that is non-toxic and harmless to the human body. Preferably, polypropylene tee 5 is used. Compared with other food-grade plastics, polypropylene is more resistant to high temperatures and has strong chemical stability, which can protect the health of drinkers.

[0033] In some embodiments, the duckbill check valve 6 is a silicone duckbill check valve 6.

[0034] In this embodiment, the duckbill one-way valve 6 needs to come into contact with the water vapor generated by the heating tank 1. The water vapor condenses into liquid in the water tank 2 and is recycled. The duckbill one-way valve 6, made of silicone material, is non-toxic and harmless, thus protecting the health of the drinker.

[0035] In some embodiments, the heating steam self-circulation absorption device 9 further includes an air duct 7 connected to the other end of the duckbill check valve 6.

[0036] In this embodiment, the air duct 7 can connect the heating tank 1, the water tank 2 and the outside air when the duckbill one-way valve 6 is open. The air enters the heating tank 1 and the water tank 2 through the duckbill one-way valve 6, thereby balancing the air pressure inside the heating tank 1 and the water tank 2 with the atmospheric pressure, thus protecting the heating tank 1 and the water tank 2 and preventing the heating tank 1 and the water tank 2 from being crushed when the air pressure inside them is lower than the atmospheric pressure.

[0037] This utility model also provides a water dispenser, including a water dispenser body 8 and a heating steam self-circulation absorption device 9 as described above, the heating steam self-circulation absorption device 9 being connected to the water dispenser body 8.

[0038] In this embodiment of the utility model, the water dispenser uses the above-mentioned heating steam self-circulation absorption device 9, which not only enables the water dispenser to achieve heating steam self-circulation absorption and solves the problem of existing water dispensers' exhaust causing trouble to the driver's cab or poor exhaust, but also saves water resources.

[0039] In some embodiments, the water dispenser further includes a water dispenser panel 10, which is connected to the water dispenser body 8.

[0040] In this implementation, the water dispenser panel 10 serves as the main interface for human-computer interaction. Its design is directly related to the user's operating experience, safety, and functional implementation, which helps to improve the user experience and make the water dispenser dispense water conveniently and quickly.

[0041] In some embodiments, the water dispenser further includes a heat preservation device 11, which is sleeved on the outside of the heating tank 1.

[0042] In this embodiment, the heat preservation device 11 makes the heat preservation effect of the heating tank better, eliminating the need for frequent heating of the heating tank 1, and solving the problems of poor heat preservation or high power consumption of the existing heating tank 1.

[0043] In some embodiments, the water dispenser further includes a pull-out water outlet device 12, which is connected to and communicates with the water tank 2.

[0044] In this embodiment, the pull-out water outlet device 12 facilitates rapid water filling of the water tank 2, is simple to operate, and does not interfere with other components of the water dispenser.

[0045] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
