Description

Technical Field

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

[0002] Room-temperature cleaning fluids don't provide optimal cleaning results, leading to the emergence of cleaning devices that use hot water and / or steam as cleaning fluids. Self-heating methods that generate hot water and / or steam through chemical reactions, however, require no electricity and therefore no external power source, offering greater convenience and flexibility.

[0003] For example, the Chinese invention patent application with application publication number CN101036571A discloses a cleaning device with a heated cleaning solution, which includes a self-heating cleaning fluid generating device. Figure 1-Figure 3 As shown, it includes a cleaning fluid container 3a, a fluid delivery nozzle 4a, and a self-heating unit 5a; the cleaning fluid container 3a is fixed on the handle 1a, and the self-heating unit 5a is assembled in the cavity of the cleaning fluid container 3a; the self-heating unit 5a includes a first chamber 6a provided with a first reactant and a second chamber 7a provided with a second reactant, and a fragile partition 8a is provided between the first chamber 6a and the second chamber 7a; the self-heating cleaning fluid generating device uses a trigger 9a to puncture the fragile partition 8a of the self-heating unit 5a, so that the first reactant in the first chamber 6a and the second reactant in the second chamber 7a are mixed and reacted, and the heat generated by the reaction is used to heat the cleaning fluid in the cleaning fluid container 3a, and the heated cleaning fluid is delivered to the cleaning part 2a through the fluid delivery nozzle 4a.

[0004] However, the existing self-heating cleaning fluid generating device still has the following technical problems: the two reactants of the self-heating reaction are pre-stored in two closed chambers, and the fragile partitions 8a of the two chambers need to be punctured by external force to allow the two reactants to react. Not only is the structure complicated, but the operation is also very inconvenient; and the puncture method makes the self-heating unit 5a only a disposable item. When any one of the reactants is consumed, the self-heating unit 5a needs to be replaced. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a self-heating cleaning fluid generating device with a simple and ingenious structure, easy operation and a reusable self-heating unit.

[0006] The technical solution of the present invention is: a self-heating clean fluid generating device, including a self-heating unit and a fluid container, characterized in that: the self-heating unit includes a self-heating container, the self-heating container is provided with a fluid injection port and a heating bag insertion port for inserting a heating bag, the fluid container is arranged on the top of the self-heating container, the fluid output port of the fluid container is connected to the fluid injection port on the self-heating container, the heating bag insertion port is arranged on the top of the self-heating container, and one side of the fluid container is hinged to the self-heating container, for exposing the heating bag insertion port when flipped upward and closing the heating bag insertion port when flipped downward.

[0007] After adopting the above structure, the present invention has the following advantages:

[0008] The self-heating unit of the self-heating clean fluid generating device of the present invention sets the fluid active material and the fluid together in the same isolated chamber, so there is no need to add a trigger, and the overall structure is simplified; secondly, the fluid container not only provides the reaction fluid for the self-heating unit, but also the fluid container is hingedly connected to the self-heating container. As long as an opening is set at the top of the self-heating container as a heating pack delivery port, the heating pack delivery port can be opened and closed by flipping the fluid container. The structural design is very clever, which enables the fluid container to achieve functional reuse and further simplifies the structure; when in use, as long as the fluid is injected into the fluid injection port of the self-heating container through the fluid container, and the heating pack is introduced by flipping the fluid container to expose the heating pack delivery port, two reactants can be added to the self-heating container. Not only is the operation very convenient, but after the exothermic reaction is over, the fluid and / or heating pack can still be added again to achieve the reuse of the self-heating unit.

[0009] Preferably, the other side of the fluid container is connected to or separated from the self-heating container by an opening button. The opening button is provided to conveniently and reliably open or close the heating pack delivery port.

[0010] Preferably, a liquid filling port is provided on the top of the fluid container, which facilitates replenishing the liquid in the fluid container.

[0011] Preferably, the apparatus further includes a steam conduit and a fluid delivery nozzle. One end of the steam conduit is connected to the upper steam region of the self-heating container, and the other end extends into the fluid container. The hot water outlet of the fluid container is connected to the fluid delivery nozzle for spraying hot water onto the cleaning portion and / or the surface being cleaned. This arrangement utilizes steam generated by the self-heating unit to heat the fluid container, thereby producing hot water for cleaning. Furthermore, since the steam conduit extends into the fluid container, the heating effect is improved.

[0012] Preferably, the steam pipe is isolated from the fluid container, and a steam release port is provided at the end of the steam pipe that penetrates the fluid container, which is open to the atmosphere. This arrangement can be used to release excessive steam pressure, making it safer and more reliable to use.

[0013] Preferably, the apparatus further comprises a steam conduit and a fluid delivery nozzle, one end of the steam conduit being connected to the upper steam region of the self-heating container, and the other end being connected to the fluid delivery nozzle for spraying steam toward the cleaning portion and / or the surface being cleaned. This arrangement allows the steam generated by the self-heating unit to be directly utilized as the cleaning fluid.

[0014] Preferably, the end of the steam pipe connected to the fluid delivery nozzle first passes through the fluid container before being connected to the fluid delivery nozzle. This arrangement allows the steam in the steam pipe to initially carry abundant condensed water due to the lower temperature of the fluid in the fluid container, thereby quickly wetting the cleaning portion and / or the surface being cleaned.

[0015] Preferably, the device further includes a three-way valve and a bleed pipe. The three-way valve has an air inlet connected to the end of the steam pipe near the fluid delivery nozzle, one air outlet connected to one end of the bleed pipe, and the other air outlet connected to the fluid delivery nozzle. The other end of the bleed pipe is connected to the atmosphere. This arrangement allows steam pressure to be released through the bleed pipe in the event of an abnormality.
