Description

Technical Field

[0001] This invention relates to the field of floor cleaning equipment technology, and more specifically to a drip steam generator capable of producing steam and hot water. Background Technology

[0002] Existing floor cleaning equipment often utilizes heating devices to generate high-temperature steam for cleaning. However, current heating devices on the market generally suffer from low energy efficiency. Specifically, the heat exchange area between the heating element and the water is small, and the contact time is short, resulting in insufficient heat transfer. The generated steam often contains a large amount of unvaporized liquid water, which not only affects the cleaning effect but also wastes energy. Furthermore, existing devices have relatively simple safety protection measures, posing a risk of overheating. Summary of the Invention

[0003] To address the problems existing in the prior art, this invention provides a drip-type steam generator that features high energy utilization, thorough steam-water separation, rapid steam generation, and high safety.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a drip-type steam generator, comprising a heating device housing with a water inlet, characterized in that an aluminum heating mechanism is provided inside the heating device housing, a water flow channel formed on the aluminum heating mechanism is connected to the water inlet, a fluid cavity is formed between the heating device housing and the aluminum heating mechanism, the fluid cavity is connected to an air outlet on the housing, and a filter screen is provided inside the air outlet.

[0005] Preferably, the aluminum heating mechanism and the heating tube are integrally die-cast.

[0006] Preferably, a thermostat (E) is also included, which is mounted on the housing of the heating device.

[0007] Preferably, the water inlet is connected to a water inlet pipe, and the water inlet pipe introduces the water into the water flow channel of the aluminum heating mechanism in the form of droplets.

[0008] Preferably, the water flow channel includes a central channel, and an outer channel is formed on the outside of the central channel, forming an overall meandering channel structure.

[0009] Preferably, the circuit also includes a temperature control switch (B) and a fuse (F), wherein the temperature control switch (B) is used to disconnect the circuit after the temperature controller (E) fails, and the fuse (F) is used to blow when the temperature control switch (B) fails and the temperature exceeds a safety threshold.

[0010] Preferably, the heating device housing is provided with a heat insulation fixing bracket and a hardware fixing bracket on the side.

[0011] Preferably, the heat-insulating mounting bracket heat-insulates the heating device housing (D) within the housing of the floor cleaning equipment, and the temperature control switch (B) and fuse (F) are mounted on the hardware mounting bracket (A).

[0012] Preferably, the heating element (L) is powered by a DC power supply with a power supply voltage of 18V-36V and a heating power of 180W-350W, and the filter (H) is a metal filter.

[0013] Preferably, an air outlet sealing silicone (J) is provided at the air outlet (K).

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. High thermal efficiency: The heating element and aluminum heating mechanism are fused together by die casting, resulting in minimal contact thermal resistance. Heat can be quickly and evenly transferred throughout the water flow channel. Water continuously flows and is heated within the channel, fully absorbing heat and significantly improving energy utilization, enabling the rapid generation of high-temperature steam above 300℃.

[0015] 2. Thorough steam-water separation and dry steam: A filter screen is installed at the outlet of the chamber. Liquid water mixed in with the steam is effectively intercepted and falls back into the chamber for secondary heating until it is completely turned into steam before being sprayed out. This ensures that the sprayed steam is dry and at the right temperature, thus improving the cleaning effect.

[0016] 3. Multiple safety safeguards: A three-level temperature control protection mechanism is set up, consisting of a thermostat, a temperature control switch, and a fuse. If any link fails, there is backup protection, which can effectively prevent dry burning and overheating and eliminate safety hazards.

[0017] 4. Compact structure and strong applicability: It adopts low-voltage DC power supply and heat-insulated fixing design, which is especially suitable for battery-powered portable floor cleaning equipment. It is installed firmly and will not be damaged by heat conduction. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] like Figures 1-2 As shown, a drip-type heating device for floor cleaning mainly consists of a hardware fixing bracket A, a temperature control switch B, a heat insulation fixing bracket C, a heating device housing D, a temperature controller E, a fuse F, a sealing silicone G, a filter H, an aluminum heating mechanism I, a gas outlet sealing silicone J, a gas outlet K, and a heating tube L.

[0024] The aluminum heating mechanism I is located inside the heating device housing D, forming a fluid cavity between them. The heating element L and the aluminum heating mechanism I are integrally formed using a die-casting process, allowing the heat from the heating element L to be directly and efficiently transferred to the entire aluminum heating mechanism I. The interior of the aluminum heating mechanism I has a tortuous water flow channel. The water flow channel M is connected to the water inlet N on the housing.

[0025] In one embodiment, the water inlet is connected to a water inlet pipe, which introduces the water into the water flow channel of the aluminum heating mechanism in the form of droplets.

[0026] In one embodiment, the water flow channel includes a central channel, and an outer channel is formed on the outside of the central channel, forming an overall meandering channel structure.

[0027] In one embodiment, a heat-insulating mounting bracket C is installed on the exterior of the heating device housing D to secure the entire heating device to the housing of the cleaning equipment, utilizing its heat insulation properties to prevent high-temperature damage to the equipment housing. A metal mounting bracket A is fixed to the side of the heating device housing D for mounting a temperature control switch B and a fuse F. The temperature controller E, temperature control switch B, and fuse F are respectively arranged on both sides of the heating device, making efficient use of space. A sealing silicone G is installed between the aluminum heating mechanism I and the heating device housing D, and an outlet sealing silicone J is provided at the connection point of the outlet K to ensure the sealing of the entire steam flow channel. The outlet K communicates with the cavity, and a metal filter H is fixed at the connection point between the two.

[0028] like Figure 3As shown, during operation, the heating element L is powered by 18V-36V DC electricity supplied by the battery pack, with the power controlled between 180W and 350W. After the power is turned on, the heating element L heats up rapidly, and the heat is evenly conducted to the aluminum heating mechanism I through the one-piece die-cast aluminum material. The temperature controller E controls the temperature to maintain the set value. At this time, the water pump drips water into the high-temperature water flow channel. During the flow of water in the channel, it partially vaporizes instantly, forming a mixture of steam and water, and continues to absorb heat along the channel. The mixture eventually enters the cavity and passes through the filter screen H at the cavity outlet. During this process, the steam directly passes through the filter screen H and is quickly sprayed from the air outlet K to the nozzle of the cleaning equipment; the unvaporized water is blocked and separated by the filter screen H, and remains inside the cavity by gravity, receiving continuous heating until it vaporizes again to form steam, and is then sprayed out again through the filter screen H, realizing the full utilization of thermal energy and the output of dry steam.

[0029] When hot water is needed, the set temperature of the thermostat E is lowered by the external control unit, and the water pump's inlet flow is increased simultaneously. Due to the lower temperature and increased water flow, the water cannot be completely vaporized into steam after flowing through the channel, and thus flows out from the steam outlet K as high-temperature hot water. By flexibly adjusting the temperature and water flow, the same device can produce both high-temperature steam and hot water, achieving multiple uses in one unit.

[0030] In terms of safety protection, thermostat E acts as the first level of control, maintaining the heating temperature normally. If thermostat E fails, causing continuous heating and the temperature to rise further and reach the operating threshold of thermostat switch B, thermostat switch B, as the second level of protection, will automatically disconnect the circuit. If thermostat switch B also fails simultaneously, and the temperature rises rapidly to an abnormal level, fuse F will act as the third level of protection, melting due to the high temperature and completely cutting off the power supply, thus preventing an accident.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
