Description

Technical Field

[0001] The present invention relates to the field of steam technology, and in particular to a pressure storage type steam generating device. Background Art

[0002] Steam is a commonly used source of thermal power. Current steam generators primarily operate by adding liquid to a container and heating it with a heating element. However, since the liquid is typically stagnant, this leads to temperature differences within the container, limiting steam generation efficiency. Stagnant liquid also easily causes impurities to accumulate within the container, making it difficult to clean and affecting performance.

[0003] Chinese utility model patent publication number CN204704801U discloses a steam generating device comprising a water input device and a steam generator connected to each other. The water input device comprises a water tank and a jet pump disposed at the output end of the water tank. The steam generator comprises a housing connected to the output end of the jet pump and a heater disposed within the housing. A high-speed hot air inlet is disposed on the side wall of the housing. A steam separator is disposed within the housing. The high-speed hot air inlet is located below the separator and opposite the jet pump. A steam purifier is disposed above the separator. A steam output port is disposed on the housing above the purifier. A sewage outlet and a water outlet are disposed at the bottom of the housing. A backwash water inlet is disposed at the bottom of the housing, equipped with a one-way valve. A backwash water outlet is disposed on the side wall of the housing below the separator. By injecting liquid into the steam generator at high speed and heating and vaporizing it, steam generation efficiency is improved while internal backwashing is simultaneously achieved.

[0004] The steam generating device is provided with a high-speed hot air inlet separately to inject high-speed hot air into the box, thereby accelerating the liquid droplets in the box and making the liquid droplets more easily vaporized.

[0005] However, when the device is in use, hot air must be input from the outside, and high-speed hot air must be turned on to accelerate the droplets, so it does not have the function of quickly generating steam. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, the present invention provides a pressure storage steam generating device.

[0007] A pressure storage steam generating device, comprising:

[0008] The steam generator has a hollow interior to form a vapor chamber, in which steam is generated;

[0009] A heating device, used to supply heat to the steam generator so that liquid water is heated in the steam generator to form steam;

[0010] The atomizing valve is installed on the steam generator to introduce liquid water into the vapor chamber;

[0011] The heating device is powered on to supply heat to the steam generator, forming high-pressure gas in the vaporization chamber. The high-pressure gas enters the atomizing valve, impacts the liquid water in the atomizing valve, and atomizes the liquid water. The formed water mist enters the vaporization chamber and quickly forms steam under the action of the heating device.

[0012] With the above structure, when using the steam generator, the user first turns on the heating device, which heats the air inside the steam generator to form high-pressure gas. The high-pressure gas moves at high speed in the closed vaporization chamber and is stored under pressure.

[0013] The user uses the water supply component to supply water to the steam generator and opens the atomizing valve. Liquid water is introduced into the steam generator through the atomizing valve, squeezing the high-pressure gas in the vaporization chamber. The high-speed high-pressure gas impacts the liquid water at the atomizing valve outlet, atomizing the liquid water into fine droplets. After entering the vaporization chamber, the droplets are impacted by the high-temperature, high-pressure gas and absorb heat, forming steam.

[0014] The above technical solution is further configured as follows: a first temperature controller is provided on the steam generator, and the first temperature controller controls the introduction of liquid water through a water pump.

[0015] With this structure, when the steam generator is turned on, the heating device first operates to heat the steam generator. After a certain heating period, the temperature in the vaporization chamber reaches the temperature set by the first thermostat. At this time, the first thermostat controls the water pump to turn on, and liquid water from the water supply component can be introduced into the vaporization chamber through the atomizing valve.

[0016] The above technical solution is further configured as follows: the atomizing valve includes a valve body group and an atomizing component, the atomizing component is located at the water outlet of the valve body group, and the high-pressure gas enters the atomizing component to impact the liquid water and atomize the liquid water.

[0017] With the above structure, when liquid water is introduced through the valve body assembly, it meets the high-pressure gas in the atomizing component, and the high-pressure gas impacts the liquid water, thereby atomizing the liquid water into extremely small droplets.

[0018] The above technical solution is further configured as follows: the atomizing component is provided with a connected water inlet channel and a steam outlet channel, and a pressurizing channel is provided between the water inlet channel and the steam outlet channel; the outer end of the pressurizing channel is connected to the steam chamber.

[0019] With the above structure, high-pressure gas moves at high speed in the vaporization chamber, enters the pressurized channel when it moves to the atomizing component, and meets the liquid water flowing out of the water inlet channel at the end of the pressurized channel, generating impact and forming atomization.

[0020] At the same time, a separate atomizing component is provided, and the meeting point of the liquid water and the high-pressure gas is provided inside the atomizing component. When the high-pressure gas enters the pressurized channel of the small space from the vaporization chamber of the large space, the pressure is further increased, the moving speed is increased, the impact on the liquid water is also greater, and a better atomization effect is achieved.

[0021] The above technical solution is further configured such that a jet portion is formed at the end of the water inlet channel, the jet portion is configured as an inverted frustum, and the outer diameter of the end connected to the water inlet is larger than the outer diameter of the end away from the water inlet.

[0022] The above technical solution is further configured such that the air inlet end of the pressurized channel is located on the side of the injection portion, and the gas impacts the outer wall of the injection portion.

[0023] With this structure, the outer side of the ejector unit connects to the end of the pressurized channel, allowing high-pressure gas to directly impact the outer wall of the ejector unit, creating a negative pressure zone between the outer wall and the end of the pressurized channel. Furthermore, because the ejector unit is shaped like an inverted cone, the high-pressure gas, after being ejected toward the cone's circumference, moves directly along the cone's outer wall, effectively spraying it at an angle. This impacts the water column ejected from the ejector unit, causing the droplets to diffuse circumferentially, forming a mist.

[0024] The above technical solution is further configured as follows: the heating device is a steam boiler, and the water pipe is arranged on the steam boiler, and the water outlet of the water pipe is connected to the atomizing valve.

[0025] With the above structure, the external water supply component is connected to the water inlet of the water pipe, and cold water enters the water pipe. When the heating device is powered on to generate heat, it conducts heat to the water pipe to heat the cold water in the water pipe. Therefore, the liquid water is already hot water when it is introduced from the water outlet of the water pipe into the atomizing valve. After being atomized by the atomizing valve, it enters the vaporization chamber and quickly reaches the vaporization temperature to form steam.

[0026] The above technical solution is further configured such that the water inlet channel and the steam outlet channel are arranged on the same straight line, and the pressurizing channel and the water inlet are arranged in a vertical state.

[0027] With the above structure, the pressurized channel and the water inlet are arranged vertically, so that the high-pressure gas directly impacts the water column without generating additional loss.

[0028] The above technical solution is further configured as follows: a pressure switch is provided on the steam generator, and the steam generator is connected to an external power supply via the pressure switch.

[0029] With the above structure, when the user uses the steam generating device, the pressure switch monitors the pressure in the vapor chamber. When the pressure in the vapor chamber is greater than the set value, the pressure switch is disconnected, causing the heating device to stop working, thereby avoiding safety problems caused by excessive pressure in the vapor chamber.

[0030] The above technical solution is further configured such that a second temperature controller is provided on the heating device.

[0031] With the above structure, a second thermostat is provided to control the temperature of the heating device to avoid safety problems caused by excessively high temperature of the heating device.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] 1. Before the liquid water enters the vapor chamber, the pressure in the vapor chamber is first stored. When the liquid water enters the vapor chamber, it is directly atomized and vaporized, and the entire device realizes instant steam generation;

[0034] 2. By heating the air in the vapor chamber to form high-speed moving high-temperature and high-pressure gas, the introduced liquid water is atomized to form small droplets and sprayed into the vapor chamber, accelerating the speed of steam formation;

[0035] 3. The heating device in the present invention has a dual function, heating the air in the vaporization chamber and the introduced liquid water at the same time, so that the liquid water is introduced in the form of hot water, further accelerating the formation of steam.

[0054] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0055] like Figure 1-6 As shown, a pressure storage steam generating device includes:

[0056] The steam generator 100 is hollow inside to form a vapor chamber a, and steam is generated in the vapor chamber a;

[0057] The heating device 200 is used to supply heat to the steam generator 100 so that the liquid water in the steam generator 100 is heated to form steam;

[0058] The atomizing valve 300 is provided on the steam generator 100 and introduces liquid water into the atomizing chamber a;

[0059] The heating device 200 is powered on to supply heat to the steam generator 100, forming high-pressure gas in the vaporization chamber a. The high-pressure gas enters the atomizing valve 300, impacting the liquid water in the atomizing valve 300, causing the liquid water to be atomized. The formed water mist enters the vaporization chamber a and quickly forms steam under the action of the heating device 200.

[0060] With the above structure, when using the steam generator, the user first turns on the heating device 200, which heats the steam generator 100, heating the air inside the steam generator 100 to form high-pressure gas. The high-pressure gas moves at high speed in the closed vaporization chamber a and is stored under pressure.

[0061] The user uses the water supply component to supply water to the steam generator 100 and opens the atomizing valve 300. Liquid water is introduced into the steam generator 100 through the atomizing valve 300, squeezing the high-pressure gas in the vaporization chamber a. The high-speed high-pressure gas impacts the liquid water at the outlet of the atomizing valve 300, atomizing the liquid water into fine droplets. After entering the vaporization chamber a, the droplets are impacted by the high-temperature, high-pressure gas and absorb heat, forming steam that is introduced into the steam equipment through the steam outlet of the steam generator 100.

[0062] Furthermore, the steam generator 100 is provided with a first temperature controller 400 , and the first temperature controller 400 controls the introduction of liquid water through a water pump.

[0063] With this structure, when the steam generator is turned on, the heating device 200 first operates to heat the steam generator 100. After a certain heating period, the temperature in the vapor chamber a reaches the temperature set by the first thermostat 400. At this time, the first thermostat 400 controls the water pump to turn on, and liquid water from the water supply component can be introduced into the vapor chamber a through the atomizing valve 300.

[0064] Furthermore, the atomizing valve 300 includes a valve body 311 group 310 and an atomizing component 320. The atomizing component 320 is located at the water outlet of the valve body 311 group 310. High-pressure gas enters the atomizing component 320 to impact the liquid water and atomize the liquid water.

[0065] With the above structure, when liquid water is introduced through the valve body 311 group 310, it encounters the high-pressure gas in the atomizing component 320, and the high-pressure gas impacts the liquid water, thereby atomizing the liquid water into extremely small droplets.

[0066] Preferably, in this embodiment, the valve body 311 assembly 310 is a one-way valve, comprising a valve body 311 with a water injection channel, a plug 312 disposed within the valve body 311, and a spring 313. The plug 312 blocks the water injection channel under the action of the spring 313. The valve body 311 assembly 310 can only introduce liquid water into the steam generator 100 from the outside.

[0067] Preferably, one end of the valve body 311 is sleeved onto the outside of the atomizing component 320 , and the spring 313 is located between the atomizing component 320 and the plug 312 .

[0068] Furthermore, the atomizing component 320 is provided with a connected water inlet channel c and a steam outlet channel d, and a pressurizing channel b is provided between the water inlet channel c and the steam outlet channel d; the outer end of the pressurizing channel b is connected to the steam chamber a.

[0069] With the above structure, high-pressure gas moves at high speed in the vaporization chamber a, enters the pressurized channel b when it moves to the atomizing component 320, and meets the liquid water flowing out of the water inlet channel c at the end of the pressurized channel b, generating impact and forming atomization.

[0070] At the same time, a separate atomizing component 320 is set, and the meeting point of liquid water and high-pressure gas is set inside the atomizing component 320. When the high-pressure gas enters the pressurized channel b in the small space from the vaporization chamber a in the large space, the pressure is further increased, the moving speed is increased, the impact on the liquid water is greater, and the atomization effect is better.

[0071] Furthermore, a jet portion 321 is formed at the end of the water inlet channel c. The jet portion 321 is arranged in an inverted frustum, and the outer diameter of the end connected to the water inlet is larger than the outer diameter of the end away from the water inlet.

[0072] Furthermore, the air inlet end of the pressurized channel b is located at the side of the injection portion 321 , and the gas impacts the outer wall of the injection portion 321 .

[0073] With this structure, the outer side of the ejection portion 321 connects with the end of the pressurized channel b. High-pressure gas directly impacts the outer wall of the ejection portion 321, creating a negative pressure zone e between the outer wall of the ejection portion 321 and the end of the pressurized channel b. Furthermore, because the ejection portion 321 is shaped like an inverted cone, the high-pressure gas, after being ejected toward the cone's circumference, moves directly along the cone's outer wall, i.e., spraying at an angle. This impacts the water column ejected from the ejection portion 321, causing the droplets to diffuse circumferentially, forming a mist.

[0074] Furthermore, the heating device 200 is a steam boiler, and the water pipe 220 is arranged on the steam boiler, and the water outlet of the water pipe 220 is connected to the atomizing valve 300.

[0075] With the above structure, the external water supply component is connected to the water inlet of the water pipe 220, and cold water enters the water pipe 220. When the heating device 200 is powered on to generate heat, it conducts heat to the water pipe 220 to heat the cold water in the water pipe 220. Therefore, the liquid water is already hot water when it is introduced from the water outlet of the water pipe 220 into the atomizing valve 300. After being atomized by the atomizing valve 300, it enters the vaporization chamber a and quickly reaches the vaporization temperature to form steam.

[0076] Preferably, the heating boiler in this embodiment is formed by casting the electric heating tube 210 and the heat-conducting body 230 as a whole. The electric heating tube 210 generates heat when energized, and transfers the heat to the heat-conducting body 230, which then transfers the heat to the steam generator 100. The water pipe 220 is disposed within the heating boiler, i.e., cast-molded with the heat-conducting body 230, and is disposed in a spiral shape within the heating boiler.

[0077] When the electric heating tube 210 is powered, it generates heat, which is then transferred to the heat-conducting body 230. The heat-conducting body 230 then transfers the heat to the water pipe 220. Cold water is introduced from the water inlet of the water pipe 220 and absorbs heat from the water pipe 220 as it moves along the spiral shape of the water pipe 220. When it is discharged from the water outlet of the water pipe 220, it becomes hot water with a certain amount of heat.

[0078] Preferably, the heat conducting body 230 in this embodiment is an aluminum medium having good thermal conductivity.

[0079] In other embodiments, the heating device 200 may also be other devices capable of generating heat by electricity. The water pipe 220 may also be arranged inside or closely on the inside or outside of the device where heat can be conducted.

[0080] Meanwhile, in this embodiment, in order to speed up the heating speed of the steam generator 100 , the heating device is wrapped around the outside of the steam generator 100 .

[0081] In other embodiments, the heating device may also conduct heat only to the bottom or any part of the steam generator 100 .

[0082] Furthermore, the water inlet channel c and the steam outlet channel d are arranged on the same straight line, and the pressurizing channel b and the water inlet are arranged in a vertical state.

[0083] With the above structure, the pressurized channel b and the water inlet are arranged vertically, so that the high-pressure gas directly impacts the water column without generating additional loss.

[0084] In other embodiments, the pressurizing channel b and the water inlet may also be arranged at an angle so that the direction in which the high-pressure gas is ejected from the pressurizing channel b intersects with the direction in which the water column is discharged.

[0085] Furthermore, the steam generator 100 is provided with a pressure switch 500 , and the steam generator 100 is connected to an external power source via the pressure switch 500 .

[0086] With the above structure, when the user uses the steam generating device, the pressure switch 500 monitors the pressure in the vapor chamber a. When the pressure in the vapor chamber a is greater than the set value, the pressure switch 500 is disconnected, causing the heating device 200 to stop working, thereby avoiding safety problems caused by excessive pressure in the vapor chamber a.

[0087] Preferably, in this embodiment, a solenoid valve 700 is provided on the steam generator 100. When the pressure in the vapor chamber a reaches or exceeds the set value, the pressure switch 500 controls the external power supply to be disconnected from the heating device 200, and at the same time the solenoid valve 700 opens to relieve the pressure in the vapor chamber a. After the pressure in the vapor chamber a is lower than the set value, the pressure switch 500 controls the external power supply to be connected, and the pressure storage action can continue.

[0088] Furthermore, the heating device 200 is provided with a second temperature controller 600 .

[0089] With the above structure, a second thermostat 600 is provided to control the temperature of the heating device 200 to avoid safety problems caused by excessive temperature of the heating device 200.

[0090] The working principle of the present invention is as follows: when the user needs to use the steam equipment, the steam generating device is powered on. After the heating device is powered on, the electric heating pipe starts to generate heat and transfers the heat to the heat-conducting body. At the same time, the water supply component on the steam equipment starts to supply water to the steam generating device. Cold water is introduced through the water inlet of the water pipe and flows in a spiral along the water pipe, while absorbing the heat of the heat-conducting body to form hot water with a certain amount of heat.

[0091] At the same time, the heat from the electric heating tube is transferred to the steam generator by the heat-conducting body, which heats up the air inside the steam generator and turns it into high-temperature, high-pressure gas. The high-temperature, high-pressure gas moves at high speed in the vaporization chamber, and the closed vaporization chamber is used to store pressure.

[0092] When hot water flows to the end of the water pipe, enters the atomizing valve, and is guided along the valve body assembly, it encounters high-temperature and high-pressure gas in the atomizing component. The high-speed moving gas impacts the hot water, causing it to atomize and form high-temperature small droplets.

[0093] Small droplets are sprayed into the vapor chamber in the form of mist, and under the action of the heating device, they absorb heat and heat up again to form steam.

[0094] When the pressure in the vapor chamber is too high and exceeds the set value, the pressure switch disconnects the steam generator from the external power supply and opens the solenoid valve, releasing the water vapor in the vapor chamber through the solenoid valve, reducing the pressure in the vapor chamber. When the pressure in the vapor chamber is lower than the set value, the pressure switch controls the steam generator to connect to the external power supply.

[0095] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can, without departing from the scope of the technical solution of the present invention, make some changes or modifications to equivalent embodiments using the technical contents disclosed above. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
