In the existing cleaning device, in order to ensure that water and the heating device can fully contact and exchange heat, the heating temperature of the heating device is usually set to be 100-150 ℃, in this case, the Ledenveron phenomenon cannot occur in the heating device, and although the heating device can generate water vapor, macroscopic water mist cannot be generated.

The heating device comprises a shell and a heating body, wherein an inner cavity is formed in the shell, the heating body is arranged in the inner cavity, a water inlet is formed in one end of the inner cavity, and an air outlet is formed in the other end of the inner cavity. In the working process of the heating device, after water enters the inner cavity from the water inlet, only one part of heating body is covered, and the surface temperature of the other part of heating body which is not covered by water flow is maintained at 280-580 ℃, so that when part of water contacts the other part of heating body which is not covered by water flow, the part of water is quickly heated and atomized, the jet head is communicated with the air outlet, and the formed water mist is ejected from the air ejecting hole of the jet head.

With respect to existing cleaning devices, a user can clearly see the water mist sprayed from the air injection holes during use of the cleaning device of the present disclosure.

For ease of understanding, the specific structure of the cleaning apparatus of the present disclosure and its principle of operation will be described in detail below in connection with one embodiment with reference to fig. 1 to 6.

As shown in fig. 1 and 2, the present disclosure provides a cleaning apparatus including a body 1, a heating device 2, and a jet head.

As shown in fig. 1, a machine body 1 is constructed as a carrier for mounting various functional elements required for a cleaning apparatus including at least a heating device 2 and a jet head.

The heating device 2 is arranged on the machine body 1, as shown in fig. 2 and 3, the heating device 2 comprises a shell 24 and a heating body 23, an inner cavity 25 is formed in the shell 24, a water inlet 21 and an air outlet 22 which are communicated with the inner cavity 25 are further arranged, and the heating body 23 extends into the inner cavity 25 of the heating device 2 from one end of the heating device 2.

The heating device 2 is configured to allow only a water flow to cover a portion of the heating body 23 and maintain the highest temperature of the surface of the other portion of the heating body 23 not covered by the water flow at 280-580 deg.c so that at least a portion of the water entering the heating device 2 from the water inlet 21 is discharged from the air outlet 22 after being atomized by heating. Wherein the maintenance of the maximum surface temperature of the other part of the heating body 23 not covered by the water flow at 280-580 ℃ means that: on the surface of the other part of the heating body 23 not covered by the water flow, the temperature of at least part of the surface is maintained at 280-580 ℃; the whole surface temperature can be maintained at 280-580 ℃, or part of the surface temperature can be maintained at 280-580 ℃ and part of the surface temperature is lower than 280 ℃.

A steam passage is provided in the interior of the jet head (not shown) and is in communication with the air outlet 22 of the heating device 2, and at least one jet hole 31 is provided in the jet head.

It will be appreciated that the cleaning apparatus of the present disclosure may also include a water supply assembly such as a water storage tank and an infusion pump (both not shown in the figures) and a cleaning assembly such as a roller brush for scrubbing a work surface. The infusion pump is used for pumping water in the water storage tank into the inner cavity 25 of the heating device 2, and then the heating body 23 heats the water to generate water mist.

As shown in fig. 1, in one embodiment of the present disclosure, the air ejection holes 31 and the roller brush 4 are provided on the bottom surface of the body 1. When the cleaning device is used for cleaning, the heating device 2 is controlled to spray water mist from the air spraying holes 31 to flush the working surface, and the rolling brush 4 is controlled to rotate to scrub the working surface.

Specifically, the steam spraying process of the cleaning apparatus of the present disclosure may include the steps of:

the cleaning device receives the air injection command, the infusion pump and the heating device 2 are started, and water in the liquid storage tank is continuously pumped into the water inlet 21 of the heating device 2 by the infusion pump.

After entering the heating device 2 from the water inlet 21, water will cover a part of the heating body 23, the temperature of this part of the heating body 23 is relatively low, typically below 100 ℃, while the maximum temperature of the surface of the other part of the heating body 23 not covered by the water flow is maintained at 280-580 ℃, above the characteristic temperature of the water, i.e. the leydig voros. The water in the area covered with the water flow on the part of the heating body 23 is repeatedly flushed toward the other part of the heating body 23 not covered with the water flow during the boiling process, and the part of the water forms a film boiling state on the surface of the other part of the heating body 23 not covered with the water flow because the temperature of the part of the heating body 23 is higher than the characteristic temperature of the water of the leydig-vorax. In the film boiling state, the heating body 23 indirectly conducts heat to the water inside through the air film attached to the surface. Because the heat conductivity coefficient of the water vapor is far smaller than that of water, the boiling speed of water drops is greatly reduced, and part of water is scattered into water mist in the scouring process before boiling.

The water mist flows out from the air outlet 22 of the heating device 2, passes through the steam passage and is finally ejected from the air ejection holes 31 of the air jet head, and at this time, the user can see that the cleaning device is normally ejecting the water mist.

Through a plurality of tests, when the highest surface temperature of the heating body 23 of the other part which is not covered by the water flow is 280-580 ℃, the flow rate of the water mist sprayed from the air spraying holes 31 is large, the pure white water mist is displayed, the visibility is high, and a user can easily observe the existence of the water mist.

Specifically, as shown in fig. 2, in one embodiment of the present disclosure, opposite ends of the heating body 23 are respectively denoted as a first end and a second end; the first end is higher than the second end when the cleaning device is placed on a horizontal surface; and the first end is configured to maintain a maximum surface temperature of 280-580 ℃. In the working process of the heating device 2, water can flow upwards gradually from below after entering the heating device 2 from the water inlet 21 below; the water is heated continuously during the flowing process, and when the water flow contacts another part of the heating body 23 which is not covered by the water flow, at least part of the water is heated and atomized, and then the water mist is discharged from the air outlet 22 above along the heating device.

To further enhance the water mist emitting effect of the cleaning device, in one embodiment of the present disclosure, the heating means 2 is configured to maintain the maximum surface temperature of the other part of the heating body 23 not covered by the water flow at 350-400 ℃. Through many experiments, when the heating device 2 is configured to maintain the highest surface temperature of the other portion of the heating body 23 not covered by the water flow at 350-400 ℃, the amount of water mist sprayed from the cleaning apparatus is large, and the user can easily see that the cleaning apparatus is spraying water mist normally.

As shown in fig. 2, in one embodiment of the present disclosure, the second end is secured to the bottom end of the interior cavity 25 and the first end is provided with a gap from the top end of the housing 24. Thus, the first end is cantilevered and does not contact the top end of the housing 24, thereby avoiding the first end from transferring more heat to the housing 24, resulting in excessive temperatures of the housing 24 and burning out other objects. In fact, in the state of water in the heating device 2, the temperature of the first end does not substantially exceed 120 ℃ even if it reaches 300 ℃ or more, the temperature of the outer surface of the casing 24.

As shown in fig. 2, in one embodiment of the present disclosure, the heating device 2 is configured to be mounted on the machine body 1 and placed at an angle to the horizontal. Thus, in the operation of the heating device 2 of the present disclosure, after water enters the heating device 2 from the water inlet 21 below, only a part of the heating body 23 is covered, so that the heating body 23 is naturally divided into a part covered by water flow and another part not covered by water flow, without additional provision.

As shown in fig. 4 and 5, in one embodiment of the present disclosure, the heating body 23 includes a heating wire 231, a heat conductive rod 233, and a heating body housing 232. The heating wire 231 is wound around the heat conductive rod 233, and the heating wire 231 extends from the region of the first end to the region of the second end. The heat conduction rod 233 and the heating wire 321 are both disposed in the heating body housing 232. The material of the heating body housing 232 may be stainless steel; the heat conductive rod 233 is used to rapidly conduct heat generated from the heating wire 321.

In one embodiment of the present disclosure, the material of the heat conductive rod 233 may be magnesium oxide. When the heat conducting rod 233 is made of magnesium oxide, heat generated by the heating wire 231 can be rapidly transferred to the heating body shell 232, water mist can be generated by heating water, and the heating wire 231 can be effectively prevented from being in contact with the heating body shell 232.

In one embodiment of the present disclosure, the magnesium oxide powder is filled between the heat conductive rod 233 and the heating body housing 232, so that the heat conductive efficiency of the heating body 23 can be improved, heat retention in the heating wire 231 is avoided, and the heating wire 231 is prevented from contacting the heating body housing 232, causing electric leakage.

As shown in fig. 4 and 5, in one embodiment of the present disclosure, the tip of the heating body 23 is further provided with an insulating sealing portion 27. The insulating seal portion 27 is provided to close the opening end of the housing 24 and fixedly connected to the second end. The insulating sealing part 27 has two purposes, namely, sealing water in the shell 24 to prevent water from flowing out of the shell 24, and preventing the heating wire from being conducted with the outside to avoid electric leakage.

As shown in fig. 2, in one embodiment of the present disclosure, the heating body 23 is provided separately from the housing 24. Wherein the first end is cantilevered as previously described and does not contact the housing 24; the second end is also only fixedly connected with the insulating sealing part 27 and cannot be contacted with the shell 24, so that the first end and the second end can be prevented from transmitting heat to the shell 24, and the shell 24 is prevented from burning other objects due to overhigh temperature. In order to further improve the sealing effect, as shown in fig. 3, in an embodiment of the present disclosure, a sealing ring 28 may be further sleeved on the insulating sealing portion 27, where the sealing ring 28 is used to seal the insulating sealing portion 27 and the housing 24, so as to further prevent water from flowing out of the housing 24.

In order to control the temperature of the first end of the heating body 23, as shown in fig. 6, in one embodiment of the present disclosure, the heating device 2 further includes a temperature detecting element 26 and a control unit (not shown in the drawings), the temperature detecting element 26 being configured to detect the temperature of the first end; the control unit is configured to control the heating power of the heating body 23 based on the temperature detection result of the temperature detection element so that the maximum surface temperature of the first end is maintained at 280-580 ℃.

As shown in fig. 6, in one embodiment of the present disclosure, the detection point of the temperature detection element 26 is disposed inside the heat conductive rod 233 at the first end. Since the heat conduction speed of the heating body 23 is fast, the measured temperature can be regarded as the temperature of the first end when the temperature detecting element 26 is disposed inside the first end of the heat conduction rod 233.

As shown in fig. 6, the temperature detecting element 26 may be a thermocouple detecting element, or may be another kind of detecting element. When the temperature detecting element 26 is a thermocouple detecting element, the measuring end of the thermocouple detecting element is disposed inside the first end.

The present disclosure also provides a heating device 2, including a housing 24 and a heating body 23, wherein an inner cavity 25 is provided in the housing 24, and a water inlet 21 and an air outlet 22 which are communicated with the inner cavity 25 are provided, and the heating body 23 is provided in the inner cavity 25; the heating device 2 is configured to allow only a water flow to cover a portion of the heating body 23 and to maintain the maximum surface temperature of the other portion of the heating body 23 not covered by the water flow at 280-580 deg.c so that at least a portion of the water entering the heating device from the water inlet 21 is discharged from the air outlet 22 after being atomized by heating. The function of each structure is referred to the aforementioned heating device 2 and will not be described in detail here.

Application scenario

The user turns on the switch of the cleaning device provided by the present disclosure.

The cleaning device receives the air injection command, the infusion pump and the heating device 2 are started, and water in the liquid storage tank is continuously pumped into the water inlet 21 of the heating device 2 by the infusion pump.

After entering the heating device 2 from the water inlet 21, water covers a part of the heating body 23, the temperature of the part of the heating body 23 is lower and is usually lower than 100 ℃, and the highest surface temperature of the other part of the heating body 23 which is not covered by water flow is maintained to be 280-580 ℃ and is higher than the characteristic temperature of the Ledenveros of the water; in this way, water repeatedly washes the other part of the heating body 23 which is not covered by the water flow during the boiling process, and the water forms a film boiling state on the surface of the other part of the heating body 23 which is not covered by the water flow because the temperature of the part of the heating body 23 is higher than the characteristic temperature of the water of the Ledenveros. In the film boiling state, the heating body 23 indirectly conducts heat to the water inside through the air film attached to the surface. Because the heat conductivity coefficient of the water vapor is far smaller than that of water, the boiling speed of water drops is greatly reduced, and part of water is scattered into water mist in the scouring process before boiling.

The water mist flows out from the air outlet 22 of the heating device 2, passes through the steam passage and is finally ejected from the air ejection holes 31 of the air jet head, and at this time, the user can see that the cleaning device is normally ejecting the water mist.

Then the user can start the rolling brush 4 at the same time, and control the rolling brush 4 to rotate to scrub the working surface while controlling the heating device 2 to spray water mist from the air spraying holes 31 to flush the working surface.
