Description

Technical Field

[0001] The present invention relates to the technical field of cleaning equipment, and in particular to a self-heating steam generating device and a cleaning fluid generating device. Background Art

[0002] Room-temperature cleaning fluids cannot provide optimal cleaning results, so cleaning devices that use hot water and / or steam as cleaning fluids have emerged. Cleaning devices that use hot water and / or steam as cleaning fluids generally require a corresponding heating device. Traditional heating devices generally use electric heating, but electric heating requires connection to an external power source, and the power cord affects user convenience. To address the above-mentioned technical issues with electric heating, a self-heating steam generating device that does not require electricity has emerged, such as the Chinese invention patent applications with application publication numbers CN103327871A and CN101036571A.

[0003] Chinese invention patent application publication number CN103327871A discloses a self-heating steam generating device comprising a heating unit 1A, an outer cover 2A, and an adsorption layer 3A. The heating unit 1A and adsorption layer 3A are located within a cavity formed by the outer cover 2A. The adsorption layer 3A is located outside of and in contact with the heating unit 1A. The heating unit 1A comprises a fluid-permeable wall 4A defining an interior space of the heating unit 1A and a fluid-activated material 5A located within the interior space of the heating unit 1A. When fluid is captured, the fluid enters the cavity formed by the outer cover 2A and further passes through the fluid-permeable wall 4A of the heating unit 1A, coming into contact with the fluid-activated material 5A within the interior space of the heating unit 1A. When the fluid-activated material 5A contacts the fluid, an exothermic reaction occurs, generating steam. The generated steam then passes through the fluid-permeable wall 4A of the heating unit 1A and the fluid-permeable wall 4A of the outer cover 2A, and is then used to clean surfaces. Furthermore, in surface cleaning applications, the heating unit 1A, outer cover 2A, and adsorbent layer 3A are typically prepared in the form of a pad. This pad effectively functions as a cleaning cloth and is attached to the end of a handle. A fluid delivery system within the handle is used to move fluid from a fluid source to the pad, or the pad is directly wetted with water. The fluid then enters the heating unit 1A and reacts exothermically with the fluid active material 5A, generating steam on the pad. The wetted pad, which is then heated and steamed, is then used to clean the surface to be cleaned. This device produces a heating effect without the need for electricity. However, this self-heating steam generating device still has the following technical problems: the self-heating pad, comprised of the heating unit 1A, outer cover 2A, and adsorbent layer 3A, lacks an isolated chamber and directly serves as the cleaning portion. After the fluid active material 5A comes into contact with the fluid, the steam generated by the exothermic reaction is directly used to clean the surface to be cleaned, resulting in uncontrollable steam output. Furthermore, after the fluid active material 5A within the pad is used up, the pad must be replaced with a new one, making it a disposable item with high cost.

[0004] A Chinese invention patent application, publication number CN101036571A, discloses a cleaning device with a heated cleaning solution. The device includes a self-heating steam generator 7B, which includes a first reactant chamber 1B containing a first reactant, a second reactant chamber 2B containing a second reactant, a frangible partition 3B, and a trigger 4B. The first reactant chamber 1B and the second reactant chamber 2B are separated by the frangible partition 3B, so that the fluid active material and the fluid are respectively disposed in two separate chambers. When force is applied to the trigger 4B, the trigger 4B pierces the frangible partition 3B, thereby causing the first reactant and the second reactant to mix and produce an exothermic reaction. Furthermore, in surface cleaning applications, a fluid reservoir 5B is provided in the handle of the cleaning device to store a large amount of cleaning fluid. The self-heating steam generator 7B is then disposed in a cavity 6B of the fluid reservoir 5B, and the heat generated by the self-heating steam generator 7B is used to heat the cleaning fluid in the fluid reservoir 5B. However, the self-heating steam generating device 7B still has the following technical problems: although the self-heating steam generating device 7B is provided with an isolation chamber, the device places the fluid active material and the fluid in two independent chambers respectively, so that the device must be equipped with a trigger device 4B to puncture the fragile partition 3B between the two chambers. Not only is the structure complex and inconvenient to use, but it is also difficult to reuse. As long as the fragile partition 3B between the first reactant chamber 1B and the first reactant chamber 2B is punctured and the reactant reaction in the two reactant chambers is completed, a new self-heating steam generating device 7B needs to be replaced, so the cost of use is also high.

[0005] Therefore, there is an urgent need to design a self-heating steam generating device with low cost, simple structure, easy use and replacement, and controllable output. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the defects of the prior art and propose a self-heating steam generating device with low cost, simple structure, easy use and replacement, and controllable output; and also propose a clean fluid generating device with low cost, simple structure, easy use and replacement, and controllable output.

[0007] Compared with the prior art, the present invention proposes a self-heating steam generating device, which is characterized by comprising a closed self-heating container, the self-heating container being provided with a fluid injection port and an openable and closable heating pack insertion port for inserting a heating pack.

[0008] The above-mentioned closed self-heating container refers to a closed or nearly closed cavity.

[0009] After adopting the above structure, the present invention has the following advantages compared with the prior art: the self-heating steam generating device of the present invention abandons the prior art of arranging the fluid active material and the fluid into a completely open structure, and arranging the fluid active material and the fluid into two completely isolated structures. Instead, the fluid active material and the fluid are creatively arranged together in the same isolated chamber, but the space between the fluid active material and the fluid is an open structure, so there is no need to add a trigger device, and the overall structure is very simple; secondly, when in use, as long as the fluid is injected through the fluid injection port and the heating pack is placed through the heating pack placement port, the two can mix to produce an exothermic reaction, so the injection of the fluid and the placement of the heating pack are very convenient, which improves the convenience of use and provides a better user experience; thirdly, after the exothermic reaction is completed, it can still be continued to be used by adding fluid and / or heating pack, without the need for disposal, replacement is also very convenient, and the cost of use is also very low; finally, since the self-heating container serving as the reaction chamber is a closed or nearly closed cavity, the steam and heat generated by the exothermic reaction are collected in the cavity, so it is convenient to regulate the output of the exothermic reaction by adding a control mechanism.

[0010] Preferably, the heating pack placement port is arranged at the top of the self-heating container. Being arranged at the top makes it more convenient to place the heating pack.

[0011] Preferably, a cover is provided at the heating pack inlet, one side of which is hinged to the self-heating container, so that the heating pack inlet can be opened and closed by flipping the cover. The opening and closing structure of the heating pack inlet is very simple and easy to use.

[0012] Preferably, a detachable cover is provided at the heating pack inlet, which is used to open and close the heating pack inlet by connecting and separating the cover. The opening and closing structure of the heating pack inlet is very simple and easy to use.

[0013] Preferably, a heating pack delivery bin is provided at the heating pack delivery port for receiving and placing the heating pack. The heating pack delivery bin is detachably connected to the heating pack delivery port. A through hole is provided on the side of the heating pack delivery bin for communicating with the inner cavity of the self-heating container and for receiving and placing the heating pack after the heating pack delivery bin is removed. The provision of a detachably connected heating pack delivery bin not only enables the opening and closing of the heating pack delivery port, but also prevents the heating pack from being randomly dropped into the water. Instead, the heating pack is stored within the range defined by the heating pack delivery bin, thereby making the exothermic reaction more controllable.

[0014] Preferably, a heating pack delivery bin for placing and taking out the heating pack is provided at the heating pack delivery port, and the heating pack delivery bin is movably connected to the heating pack delivery port up and down, and a through hole is provided on the side of the heating pack delivery bin for communicating with the inner cavity of the self-heating container and for taking out and placing the heating pack after the heating pack delivery bin is moved up. The provision of a heating pack delivery bin that is movably connected up and down not only realizes the opening and closing of the heating pack delivery port, but also prevents the heating pack from being randomly dropped into the water. Instead, it is stored within the range defined by the heating pack delivery bin, making the exothermic reaction more controllable. Moreover, since the heating pack delivery bin can be moved up and down, it is also convenient to quickly stop the exothermic reaction by moving the heating pack delivery bin up in an emergency.

[0015] Preferably, an automatic pop-up structure is provided between the heating pack delivery port and the heating pack delivery bin, which is used to automatically pop out when the heating pack delivery bin is pressed and automatically retract when pressed again. The automatic pop-up structure allows the heating pack delivery bin to move up and down by pressing the heating pack delivery bin, making operation more convenient and labor-saving.

[0016] Preferably, the device further comprises a fluid container, which is connected to the fluid injection port of the self-heating container. This arrangement can conveniently provide reaction fluid for the exothermic reaction of the self-heating container.

[0017] Compared with the prior art, the present invention proposes a cleaning fluid generating device, characterized in that it includes the above-mentioned self-heating steam generating device, and the self-heating container of the self-heating steam generating device is also provided with a steam output port for providing steam to the cleaning part and / or the surface to be cleaned.

[0018] Compared with the prior art, the present invention also proposes a cleaning fluid generating device, which is characterized in that: it includes the above-mentioned self-heating steam generating device, and also includes a hot water container for storing a cleaning medium. The self-heating steam generating device is in thermal contact with the hot water container, and is used to transfer the heat generated by the self-heating steam generating device to the cleaning medium in the hot water container. The hot water container is also provided with a hot water output port for providing hot water to the cleaning part and / or the surface to be cleaned.

[0019] After adopting the above structure, compared with the prior art, the present invention has the following advantages: the cleaning fluid generating device of the present invention has low use cost, simple structure, easy use and replacement, and controllable steam / hot water output.

The automatic pop-up structure can adopt existing technology and will not be repeated here; it also includes a fluid container 6, which is connected to the fluid injection port 2 of the self-heating container 1.

[0087] Example 9:

[0088] like Figure 23 、 24 As shown, this embodiment provides a cleaning fluid generating device, which includes the self-heating steam generating device described in Example 8, and also includes a hot water container for storing a cleaning medium. The self-heating steam generating device is in thermal contact with the hot water container, and is used to conduct the heat generated by the self-heating steam generating device to the cleaning medium in the hot water container. The hot water container is also provided with a hot water output port 8 for providing hot water to the cleaning portion 18 and / or the surface to be cleaned.

[0089] In this embodiment, the fluid container 6 is directly used as a hot water container; a liquid filling port 9 is provided on the top of the fluid container 6 .

[0090] In this embodiment, the thermal contact structure between the self-heating steam generating device and the hot water container, that is, the thermal contact structure between the self-heating steam generating device and the fluid container 6, is achieved by placing the fluid container 6 on the top of the self-heating container 1 to directly transfer heat; the self-heating container 1 and the fluid container 6 are formed as one piece, and the self-heating container 1 and the fluid container 6 are formed by arranging a partition 16 horizontally in the middle of the same container; the top of the fluid container 6 is provided with a feeding pipe 17 extending downward and connected to the top of the self-heating container 1, the feeding pipe 17 is isolated from the fluid container 6, and the top of the feeding pipe 17 is the heating bag feeding port 3.

[0091] In this embodiment, a fluid delivery nozzle 12 is further included. The hot water outlet 8 of the fluid container 6 is connected to the fluid delivery nozzle 12 for spraying hot water toward the cleaning portion 18 and / or the surface to be cleaned.

[0092] In this embodiment, a first pump 14 is provided between the cold water outlet 13 of the fluid container 6 and the fluid inlet 2 on the self-heating container 1 ; a second pump 15 is provided between the hot water outlet 8 of the fluid container 6 and the fluid delivery nozzle 12 .

[0093] The operating principle of the cleaning fluid generating device of this embodiment is as follows: a first pump 14 draws a certain amount of fluid from the fluid container 6 into the self-heating container 1. Clean water flows from the self-heating container 1 into the heating pack delivery chamber 22, covering the heating pack 7. The heating pack 7 reacts exothermically with the fluid and generates heat. Since the fluid container 6 is placed on top of the self-heating container 1, the heat from the self-heating container 1 is transferred to the fluid container 6, heating the fluid in the fluid container 6. A second pump 15 delivers the heated fluid in the fluid container 6 to the fluid delivery nozzle 12 and sprays it onto the cleaning portion 18 and / or the surface to be cleaned for cleaning. When the reaction needs to be stopped or the heating pack 7 needs to be replaced, the top of the heating pack delivery chamber 22 is simply pressed to eject the heating pack delivery chamber 22. The heating pack 7 pops up and is isolated from the water, thereby stopping the reaction. After ejection, the heating pack 7 can be replaced through the second through-hole 23 on the side of the heating pack delivery chamber 22. The top of the heating pack delivery chamber 22 is pressed again to retract the heating pack delivery chamber 22 downward.

[0094] Figure 24 The diagram illustrates the structure of a mop that uses a hot water cleaning method and applies the cleaning fluid generating device. The upper and lower surfaces of the cleaning portion 18 of the mop are flat, and the fluid delivery nozzle 12 is arranged on the bottom surface of the self-heating container 1. The bottom surface of the self-heating container 1 is placed close to the top surface of the cleaning portion 18, and the hot water output port 8 of the fluid container 6 is connected to the fluid delivery nozzle 12, so that hot water can be sprayed onto the cleaning portion 18.

[0095] The drawings of Example 8 and Example 9 can be combined with each other when necessary.
