Description

Technical Field

[0001] This invention relates to the field of steam generating device technology, and specifically to a self-heating steam generating device. Background Technology

[0002] Room temperature cleaning fluids do not provide optimal cleaning results, therefore cleaning devices that use hot water and / or steam as cleaning fluids have emerged. Self-heating methods that generate hot water and / or steam through chemical reactions offer greater convenience and flexibility because they require no electricity and thus no external power source.

[0003] For example, Chinese invention patent application CN101036571A discloses a self-heating steam generator, but existing self-heating steam generators do not consider how to stop the exothermic reaction in emergency situations. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a self-heating steam generator with an emergency liquid discharge function that stops the exothermic reaction in an emergency.

[0005] The technical solution of the present invention is: a self-heating steam generator with an emergency liquid discharge function, comprising a self-heating unit, wherein the self-heating unit includes a self-heating container for storing fluid active materials and reaction fluid and serving as a reaction chamber, characterized in that: the self-heating container is provided with a liquid discharge port for discharging the reaction fluid, and further includes a liquid discharge device disposed at the liquid discharge port for opening and closing the liquid discharge port, the liquid discharge device including a liquid discharge button and a liquid discharge valve, the liquid discharge valve being disposed at the liquid discharge port, the liquid discharge button being exposed or embedded in the self-heating container, and the liquid discharge button being connected to the liquid discharge valve via a connector for pressing the liquid discharge button to control the opening and closing of the liquid discharge valve.

[0006] With the above structure, the present invention has the following advantages:

[0007] The self-heating steam generator with emergency liquid discharge function of the present invention is provided with a liquid discharge port and a liquid discharge device at the liquid discharge port. In this way, in an emergency, the reaction fluid in the reaction chamber can be discharged through the liquid discharge device, so that the fluid active material stops the exothermic reaction due to the lack of reaction fluid. Moreover, the liquid discharge device has a simple structure and works by mechanical pressing, which is more energy-saving and power-saving.

[0008] Preferably, the drain valve includes a valve seat and a plunger that can move up and down within the valve seat. One end of the valve seat is installed at the drain port and is connected to the drain port. The drain button is located directly above the valve seat. One end of the connector is connected to the drain button, and the other end is connected to the plunger. Pressing the drain button causes the plunger to move up and down. The side of the valve seat also has a hollow area, which is used to isolate or connect the drain port and the hollow area when the plunger moves up and down. This drain valve only needs to have a hollow area on the side of the valve seat and a plunger inside. The drain port can be opened or closed by the up and down movement of the plunger. The structure is simple and ingenious, and it only requires mechanical pressing, making it easy to operate and energy-saving.

[0009] Preferably, an elastic recovery device is provided between the plunger and the valve seat on the side away from the connector, to restore its original shape when the drain button is released. Placing the elastic recovery device between the plunger and the valve seat not only facilitates installation but also results in a more compact structure.

[0010] Preferably, the height of the plunger is less than the height of the hollow area. This design allows for a shorter pressing stroke of the drain button, making operation more convenient, and also allows for a more compact valve seat design.

[0011] Preferably, the drain port is located at the bottom of the self-heating container, the drain button is located at the top of the self-heating container, the top of the valve seat is installed at the drain port and communicates with the drain port, the top of the connector is connected to the drain button, and the bottom is connected to the top of the plunger. This arrangement makes the layout of the components more reasonable.

[0012] Preferably, the hollowed-out area includes multiple strip-shaped through holes evenly arranged side-by-side in the middle of the valve seat side. This arrangement makes the processing of the hollowed-out area more convenient.

[0013] Preferably, an emergency container is also included, with the drain outlet connected to the fluid inlet of the emergency container. The emergency container stores the discharged reaction fluid, preventing environmental pollution, and allows for reuse after recovery.

[0014] Preferably, the self-heating container is positioned above the emergency container, and the self-heating container and the emergency container are formed by a partition in the middle of the same container. The upper chamber is the self-heating container, and the lower chamber is the emergency container. The drain outlet is located on the partition. By positioning the self-heating container above the emergency container and the drain outlet on the partition, the reaction fluid can flow directly to the emergency container under its own gravity when the drain outlet is open. This eliminates the need for additional power equipment to transport the reaction liquid flowing out of the drain outlet, simplifying the structure and saving energy.

[0015] Preferably, the system also includes a fluid container, which has a fluid inlet and a heating pack outlet. The fluid outlet of the fluid container is connected to the fluid inlet of the self-heating container. This configuration allows for the refilling of fluid and / or the heating pack through the fluid inlet and heating pack outlet, enabling the reuse of the self-heating unit. Furthermore, the fluid container facilitates the replenishment of the fluid required for the reaction.

[0016] Preferably, the self-heating container is provided with a fluid inlet and a heating pack outlet for dispensing a heating pack, and the fluid output of the emergency container is connected to the fluid inlet of the self-heating container. This configuration serves as both a fluid supply container and a fluid recovery container, further simplifying the structure. Attached image description:

The self-heating container 2 has a discharge port 3 for discharging the reaction fluid. It also includes a liquid discharge device 4 located at the discharge port 3 for opening and closing the port 3. The liquid discharge device 4 includes a liquid discharge button 11 and a liquid discharge valve 12. The liquid discharge valve 12 is located at the discharge port 3. The liquid discharge button 11 is exposed or embedded in the self-heating container 2. In this embodiment, the liquid discharge button 11 is exposed on the self-heating container 2. The liquid discharge button 11 is also connected to the liquid discharge valve 12 via a connector 15, and is used to control the opening and closing of the liquid discharge valve 12 by pressing the liquid discharge button 11.

[0028] The drain valve 12 includes a valve seat 16 and a plunger 17 that can move up and down within the valve seat 16. One end of the valve seat 16 is installed at the drain port 3 and is connected to the drain port 3. The drain button 11 is located directly above the valve seat 16. One end of the connector 15 is connected to the drain button 11 and the other end is connected to the plunger 17. When the drain button 11 is pressed, the plunger 17 moves up and down. The side of the valve seat 16 is also provided with a hollow area 18, which is used to isolate or connect the drain port 3 and the hollow area 18 when the plunger 17 moves up and down. An elastic recovery device 20 is also provided between the side of the plunger 17 away from the connector 15 and the valve seat 16, which is used to restore it to its original shape when the drain button 11 is released. The height of the plunger 17 is less than the height of the hollow area 18. In this embodiment, the drain port 3 is located at the bottom of the self-heating container 2, the drain button 11 is located at the top of the self-heating container 2, the top of the valve seat 16 is installed at the drain port 3 and communicates with the drain port 3, the hollow area 18 includes a plurality of strip-shaped through holes 19 evenly arranged in the middle of the side of the valve seat 16, the height of the plunger 17 is less than the height of the strip-shaped through holes 19, the top end of the connector 15 is connected to the drain button 11, and the bottom end is connected to the top of the plunger 17, the elastic recovery device 20 includes a compression spring, and the compression spring is located between the bottom of the plunger 17 and the valve seat 16.

[0029] It also includes an emergency container 5, with the self-heating container 2 positioned above it. The self-heating container 2 and the emergency container 5 are formed by a partition 10 in the middle of the same container. The upper chamber is the self-heating container 2, and the lower chamber is the emergency container 5. The drain port 3 is located on the partition 10 and is connected to the fluid input of the emergency container 5. The self-heating container 2 has a fluid inlet 6 and a heating pack inlet 7 for adding a heating pack. It also includes a fluid container, the fluid output of which is connected to the fluid inlet 6 of the self-heating container 2. In this embodiment, the emergency container 5 is directly used as the fluid container, i.e., the fluid output 9 of the emergency container 5 is connected to the fluid inlet 6 of the self-heating container 2. A liquid inlet pump 13 and a one-way valve are also provided between the fluid output 9 of the emergency container 5 and the fluid inlet 6 of the self-heating container 2. Of course, the fluid container and the emergency container 5 can also be set simultaneously, with the fluid container serving as a supply device for the reaction fluid and the emergency container 5 as a recovery device for the reaction fluid. This method is more complex than directly using the emergency container 5 as the fluid container.

[0030] The working process of the self-heating steam generator with emergency liquid discharge function in this embodiment is as follows: Start the liquid inlet pump 13 to draw a certain amount of fluid from the emergency container 5 into the self-heating container 2. The fluid covers the fluid active material, and then the liquid inlet pump 13 stops working. The fluid active material heats up when it comes into contact with the fluid, and the water in the self-heating container 2 boils to produce hot water and steam. The steam in the self-heating container 2 is sprayed onto the cleaning part 8 and / or the surface being cleaned through the steam pipe 14.

Release the drain button, the plunger 17 moves upward under the drive of the compression spring, the drain port 3 is separated from the hollow area 18, the drain valve closes, and the reaction fluid in the self-heating container 2 no longer flows out.
