Technical Field

[0001] This utility model relates to the field of temperature and humidity control technology, and in particular to a heated steam humidifier. Background Technology

[0002] In the textile industry, textiles require steam heating and humidification, necessitating the use of humidifiers. These devices increase the humidity of an environment by heating water in a tank to convert it into steam, which then escapes to achieve humidification. Most commonly used humidifiers rely on rapid heating with a water-heating rod to generate steam. However, this method offers relatively low humidity control accuracy and is unsuitable for applications requiring measurement or other slow, controlled humidity levels. Furthermore, it necessitates manual operation and monitoring, reducing safety and efficiency. Summary of the Invention

[0003] In view of the above-mentioned defects or deficiencies, the purpose of this utility model is to provide a heated steam humidifier.

A pneumatic component for controlling the steam quantity is installed on the heating mechanism. A control switch is installed on the steam supply mechanism, and a temperature and humidity sensor and a pressure sensor are installed on the sealed container. The heating mechanism is equipped with a steam generator, and a water level sensor is installed on the steam generator. The input end of the controller is connected to the temperature and humidity sensor, the pressure sensor, and the steam generator, and the output end of the controller is connected to the control switch, the pneumatic component, and the switch of the heating mechanism.

[0019] The present invention will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.

[0020] like Figure 1-3 As shown, this utility model provides a heated steam humidifier, including: a heating mechanism 3 and a controller 13. The input end of the heating mechanism 3 is connected to a steam supply mechanism 5, and the output end of the heating mechanism 3 is connected to a sealed container 2. A pneumatic component 4 for controlling the amount of steam is installed on the heating mechanism 3. A control switch 53 is installed on the steam supply mechanism 5, and a temperature and humidity sensor 21 and a pressure sensor 22 are installed on the sealed container 2. The heating mechanism 3 is equipped with a steam generator 31, and a water level sensor 311 is installed on the steam generator 31. The input end of the controller 13 is connected to the temperature and humidity sensor 21, the pressure sensor 22, and the steam generator 31, and the output end of the controller 13 is connected to the control switch 53, the pneumatic component 4, and the switch of the heating mechanism 3. Preferably, a fixing plate 1 is also included, and the heating mechanism 3, the pneumatic component 4, and the steam supply mechanism 5 can all be centrally mounted on the fixing plate 1.

[0021] In this invention, the heating mechanism 3 includes: a heat-conducting fixing base 34, a steam generator 31 installed inside the heat-conducting fixing base 34, distilled water inside the steam generator 31, the steam generator 31 connected to the pneumatic assembly 4 via a second air pipe 7, and the steam generator 31 connected to the sealed container 2 via a first air pipe 6. A heating element 33 is provided on the lower surface of the heat-conducting fixing base 34, and a temperature detection component 32 for detecting the heating temperature is provided on one side of the heating element 33. Specifically, the steam generator 31 is placed tightly against the groove of the heat-conducting fixing base 34, the steam generator 31 contains distilled water, and a spherical air stone 11 is connected to the free end of the second air pipe 7, with the spherical air stone 11 placed in the distilled water.

[0022] In this invention, a temperature detection component 32 and at least one heating element 33 are attached to the lower surface of the heat-conducting mounting base 34. Silver-plated copper wires are welded to both sides of the heating element 33, allowing current to flow through the entire element. A temperature detection component 32 for detecting the heating temperature is provided on one side of the heating element 33. The temperature detection component 32 includes a temperature sensor and a temperature transmitter, connected by a wire. The temperature sensor is attached to the bottom of the heat-conducting mounting base 34. Preferably, the heating element 33 is a PCT heating element and a gold-aluminum shell resistor. Additionally, a thermally conductive graphite sheet is placed on the side of the steam generator 31, and the heat-conducting mounting base 34 is made of aluminum. The aluminum shell effectively conducts heat generated by the gold-aluminum shell resistor, while the thermally conductive graphite sheet effectively transfers heat from the mounting base to the steam generator 31, reducing heat loss. During installation, the aluminum shell of the heat-conducting mounting base 34 needs to be isolated to prevent heat loss from the steam generator 31.

[0023] Furthermore, the heat-conducting mounting base 34 is covered with adhesive-backed insulating foam on its sides, which can also reduce heat loss. The heat-conducting mounting base 34 can also be surrounded by an outer frame box. The outer frame box serves two purposes: firstly, it prevents accidental contact and potential danger when the aluminum alloy casing resistor heats up; secondly, it also provides insulation.

[0024] In this utility model, the pneumatic component 4 includes: a solenoid valve 41, a pressure reducing valve 43, and a pressure gauge 42. The solenoid valve 41, pressure reducing valve 43, and pressure gauge 42 are connected to the air pipe according to the air circuit diagram, such as... Figure 2 As shown, by adjusting the pressure gauge 42, the air intake can be reduced or increased, ensuring the degree of air intake under the same humidity conditions. The air intake can be controlled by the electrically controlled solenoid valve 41.

[0025] Optionally, the pneumatic assembly 4 may include two sets, configured as dry and humid air sets. One solenoid valve 41 is directly connected to the sealed container 2 via the fifth air pipe 10, supplying it with dry air; the other solenoid valve 41 extends into the bottom of the steam generator 31 via the second air pipe 7. The steam generator 31 is connected to the sealed container 2 via the first air pipe 6, supplying it with humid air. In this way, the humidity inside the sealed container can be regulated and controlled. A gland is installed at the opening of the sealed container 2 for fixing and sealing the air pipes.

[0026] More preferably, in this invention, the pneumatic component 4 further includes: a first filter 44, an air purifier 45, and a second filter 46. The air coming in from the air compressor 12 passes through the first filter 44, the air purifier 45, and the second filter 46 in sequence before entering the solenoid valve 41, ensuring the purity of the air entering the solenoid valve 41.

[0027] Furthermore, the temperature detection assembly 32 includes a temperature sensor and a temperature transmitter, which are connected by a wire, and the temperature sensor is attached to the thermally conductive mounting base 34.

[0028] At the bottom, a temperature transmitter can indirectly reflect the real-time water temperature inside the steam generator 31. Specifically, a water level sensor 311 is attached to the surface of the steam generator 31 to detect the water level, thereby allowing distilled water to be replenished to the steam generator 31 from the water tank 52 in real time.

[0029] Preferably, the steam generator 31 is connected to a steam supply mechanism 5 via a third air pipe 8, and a check valve is provided on the third air pipe 8. The steam supply mechanism 5 includes a water tank 52 and a water pump 51, which are connected via a fourth air pipe 9. Alternatively, a purification filter can be installed on the water tank 52 for filtering the water.

[0030] It should be noted that the output of the controller 13 is also connected to a display screen 14. The controller 13 is a microcontroller or a condition controller. It can set parameters as needed to control the entire device.

[0031] It should be noted that in this invention, the first gas pipe 6 is a natural gas pipe, which has good heat insulation properties. The sealed container 2 is a container for holding the item to be tested, such as textiles. The humidifying device provides a slow humidity change environment for the sealed container 2 to detect the parameters of the textiles. Preferably, the sealed container 2 is equipped with a temperature and humidity sensor 21 and a pressure sensor 22. A through hole is provided in the middle of the upper surface of the sealed container 2 to facilitate the installation of the temperature and humidity sensor 21 and the pressure sensor 22 for detecting the temperature, humidity, and pressure of the sealed container 2.

[0032] The working process of this utility model is as follows:

[0033] When it is necessary to humidify the textiles in the sealed container 2, turn on each switch, and heat is conducted through the heating element 33 to the heat-conducting fixing seat 34, and then to the steam generator 31 to generate humid air.

[0034] Pneumatic component 4 provides air pressure, which is slowly forced into the sealed container 2 through the second air pipe 7 via spherical air stone 11. This provides a slow humidity change environment for the item to be tested placed inside the sealed container 2, facilitating the detection of the item's parameters. Throughout the process, controller 6 monitors and displays various parameters. If any parameter deviates from the preset range, the control device shuts down or alarms, ensuring the safety of the entire process.

[0035] This invention utilizes a heating element for slow heating and conduction, and the combination of a pneumatic component and a spherical air stone 11 ensures slow humidification inside the sealed container, making it suitable for measurement or other applications requiring slow supply and control of humidity.

[0036] It will be apparent to those skilled in the art that the above specific examples are merely preferred embodiments of this utility model. Therefore, any improvements or modifications that those skilled in the art may make to certain parts of this utility model still embody the principles of this utility model and achieve its purpose, and all fall within the scope of protection of this utility model.
