For ease of understanding, the specific structure of the steam generator of the present disclosure and its operating principle will be described in detail with reference to fig. 1 to 7 in conjunction with an embodiment.

Referring to fig. 1, the present disclosure provides a steam generator that may be used on a variety of intelligent devices requiring steam generation, such as a wireless steam floor scrubber, a wireless steam mop, a wireless eye fumigator, and the like. The steam generator of the present disclosure is a miniature device that can be used in a wireless device with less power, and that is powered by the battery of the wireless device itself. Of course, the steam generator of the present disclosure may also be provided on a wired device, which is not described in detail herein. In one embodiment of the present disclosure, the steam generator is provided on a handheld cleaning device, such as a handheld cleaning appliance, such as a handheld cleaner, handheld vacuum cleaner, handheld floor washer, or the like, as is well known to those skilled in the art. The self-moving cleaning device can also be a sweeping robot, a mopping robot, a sweeping and mopping integrated robot and the like. The cleaning apparatus includes a main body 51, a cleaning liquid tank, a sewage tank, a floor brush assembly 52, etc., which are provided on the main body 51. The floor brush assembly 52 includes a floor brush housing 53, and a floor brush 54 connected to the floor brush housing, and a steam generator is disposed in a floor brush cavity of the floor brush housing 53 and configured to provide steam to the work surface.

When the cleaning apparatus of the present disclosure is a floor scrubber, a user may perform a cleaning operation using the floor scrubber by pushing the hand-held portion of the floor scrubber over the floor and cleaning the work surface with the floor brush 54 in the floor brush assembly 52. During cleaning, the cleaning liquid tank on the scrubber will supply water to the brush assembly 52 to wet the brushes 54 for cleaning the floor. At the same time, the steam generator can generate steam under the action of the heating body 2 in the heating cavity 11, and the steam can act on the working surface to clean dirt on the working surface at high temperature, so that the cleaning effect of the floor washing machine is improved. The wastewater tank on the main body 51 is configured to store wastewater generated during the cleaning process.

In one embodiment of the present disclosure, referring to the orientation of the view of fig. 2, the steam generator has opposite first and second ends along the axial direction of the steam generator.

Wherein the housing 1 comprises a heating chamber 11 with an open end. The heating body 2 is arranged in the heating chamber 11. Specifically, referring to fig. 7, the heating body 2 has a first end connected to an open end of the heating chamber 11 and a second end configured to penetrate into the heating chamber 11 of the housing 1 from the open end. The lead wire 21 provided in the heating body 2 is configured to extend outwardly from the first end so as to be connected to an external electrical connector for supplying power to the heating body 2 to perform a heating operation. In one embodiment of the present disclosure, as shown in fig. 6 and 5, a scale storage chamber 14 is further provided on the steam generator in communication with the heating chamber 11, the scale storage chamber 14 being disposed at a side adjacent to the high temperature region and configured to receive scale. As the heating body 2 can continuously heat the water in the heating cavity 11 during the use of the steam generator, the water containing the soluble calcium-magnesium compound can be separated out of insoluble calcium salt or magnesium salt after boiling, namely scale particles; and scale particles in the steam may adhere to the wall of the heating chamber 11 after contacting the wall of the heating chamber 11. Thus, as the steam generator is used, scale on the wall of the heating chamber 11 builds up more and more. After setting up and depositing the dirty chamber 14 for the in-process that the high temperature steam of mixed scale granule flows to gas outlet 13, the incrustation scale granule can deposit in depositing dirty chamber 14 under the effect of gravity, thereby slows down the deposition rate of incrustation scale, and then prolongs steam generator's life. In one embodiment of the present disclosure, in order to achieve the connection of the heating body 2 with the housing 1, referring to fig. 3, 7, a first end of the heating body 2 is provided with a connection piece 15.

Referring to fig. 4, a sealing member is provided at a first end position of the heating body 2 and configured to isolate at least an end surface of the first end of the heating body 2 from the outside. In order to ensure that the heating body 2 can keep good insulation and pressure resistance, prevent external water and/or moisture from entering the inner cavity 23 of the heating body 2, solve the problem that the heating body 2 is easy to wet in a high-temperature and high-humidity environment, the steam generator disclosed by the utility model is provided with a sealing element at the first end of the heating body 2 so as to achieve the purpose of isolating the heating body 2 from the external environment, thereby the heating body 2 can perform heating work in the high-temperature and high-humidity environment, and can always have good insulation and pressure resistance in the working process. Effectively avoid external water or moisture to enter the inside of heating member, lead to its inside to wet, insulating withstand voltage reduces, appear electric leakage, interfering signal, short circuit's risk.

In one embodiment of the present disclosure, referring to fig. 3 and 4, the heating body 2 includes a sleeve 22 having an inner cavity 23, and a heat conductive rod 26. The heat conducting rod 26 is arranged in the inner cavity 23 of the sleeve 22, and the heat conducting rod 26 is provided with a heating wire 261; the wires 21 include at least a heater wire 262, the heater wire 262 being connected to the heater wire 261 and configured to pass outwardly from the first end of the sleeve 22.

The thermally conductive rod 26 is configured to extend along the length of the sleeve 22, and when installed, the thermally conductive rod 26 is configured to extend from the first end of the sleeve 22 into the interior cavity 23 of the sleeve 22. With continued reference to fig. 5, the thermally conductive rod 26 is configured to extend into the interior cavity 23 of the sleeve 22 adjacent the second end of the sleeve 22. Referring to fig. 4 and 5, the heating wire 261 may be wound around the outer surface of the heat conductive rod 26 such that heat generated by the heating wire 261 may be transferred to the sleeve 22 via the heat conductive rod 26 to heat the liquid located in the heating chamber 11. In a specific embodiment of the present disclosure, the heating wire 262 and the heating wire 261 may be integrated, and after the heating wire 261 is wound on the heat conducting rod 26, the heating wire 262 is penetrated out from the first end of the sleeve 22, and the heating wire 261 is energized to generate heat by communicating the heating wire 262 with an external electrical connector, so as to achieve the purpose of heating the heat conducting rod 26.

In one embodiment of the present disclosure, a first support 24 is provided in the inner cavity 23 of the sleeve 22 at a position outside the heat conductive rod 26, and the heating wire 262 is configured to communicate with the heating wire 261 after passing through the first support 24. The first support 24 is configured to support the heating wire 262. In this embodiment, the first supporting body 24 is located at the first end of the heat conducting rod 26 and is configured to support the first end of the heat conducting rod 26, so as to fix the heat conducting rod 26, avoid shaking the heat conducting rod 26, and improve stability between the structures. The first supporting body 24 and the heat conducting rod 26 may be made of the same material, such as magnesium oxide, and after the heating wire wires 262 pass through the first supporting body 24, the first supporting body 24 may provide a certain support for the heating wire wires 262, so as to avoid short circuit caused by contact between the two heating wire wires 262; in addition, since the heating wire 262 has a certain flexibility, after the heating wire 262 is supported by the first supporting body 24, the heating wire 262 is prevented from bending and suspending, so that the heating wire 261 is pulled to separate from the heat conducting rod 26.

In one embodiment of the present disclosure, referring to fig. 4 and 5, the seal is a seal plug 31 disposed in the lumen 23 of the cannula 22 and located outside of the first support 24, the seal plug 31 being configured for an interference fit with the inner wall of the cannula 22. Through setting up with sleeve pipe 22 inner wall interference fit's sealed end cap 31, can effectively reduce outside water or moisture and enter into in the inner chamber 23 of heating member 2 to can make the inner chamber 23 of heating member 2 have dry, good operational environment all the time, so can prolong the life of heating member 2. The sealing plug 31 may be a plastic piece or other suitable sealing material known to those skilled in the art. The sealing plug 31 can be plugged into the inner cavity 23 of the sleeve 22 and is in contact fit with the first supporting body 24 during installation, and due to the characteristics of the sealing plug 31, the sealing plug is in interference fit with the inner wall of the sleeve 22, so that external water vapor is prevented from entering the inner cavity 23 of the sleeve 22. Of course, in another embodiment of the present disclosure, a sealant may be poured into the inner cavity of the sleeve 22, and the sealant is cured to form the sealing plug 31.

The sealing plug 31 is provided with a through hole 311, and the heating wire 262 is configured to be interference fit with the through hole 311. Specifically, in use, the heater wire 262 is configured to pass through the through hole 311 of the sealing plug 31 and then connect with an external electrical connector. The heating wire 262 is in interference fit with the through hole 311, so that the sealing performance between the sealing plug 31 and the heating wire 262 can be improved, and external water or moisture can be effectively reduced from entering the inner cavity 23 of the heating body 2 through the through hole 311.

In a specific embodiment of the present disclosure, the sealing plug 31 is configured to be made of rubber containing fluorine, and the fluororubber has the characteristics of high temperature resistance and good sealing property, so as to seal the inner cavity 23 of the sleeve 22, and prevent external water or moisture from entering the inner cavity 23.

In one embodiment of the present disclosure, a second support 25 is disposed within the interior cavity 23 of the cannula 22, the second support 25 being disposed within the interior cavity 23 of the cannula 22 at a location outside of the sealing plug 31. The heating wire 262 is configured to pass through the second supporting body 25 and to be supported by the second supporting body 25. In this embodiment, since the heating wire 262 is generally formed of a flexible wire, in order to avoid the situation that the heating wire 262 is bent and the wire inside the heating wire 262 is moved and deviated due to extrusion during installation and use or shaking during use, the heating wire 262 needs to be supported by the second supporting body 25 to improve the use safety of the device.

In one embodiment of the present disclosure, the second support 25 is ceramic glue cured at the open end of the lumen of the cannula 22 and configured to seal the open end of the cannula 22. In the present embodiment, referring to fig. 4 and 5, after the heat conduction rod 26 and the heating wire 261 are installed in the inner cavity 23 of the heating body 2, the heating wire 262 is protruded from the first end of the heating body 2 to the sleeve 22. In order to improve the sealing performance of the inner cavity 23 of the heating body 2, the heating wire lead 262 passes through the through hole 311 of the sealing plug 31 and is in interference fit with the through hole 311, and the heating wire lead 262 is fixed and simultaneously plays a role in sealing the inner cavity 23 of the heating body 2. After the sealing plug 31 is assembled, the opening end of the sleeve 22 adjacent to the heating body 2 is also filled with ceramic glue for sealing the opening end of the inner cavity 23, and after a certain time, the ceramic glue is solidified to form the second supporting body 25 for supporting the heating wire lead 262. The second support body 25 can thus not only support the heater wire 262, but also seal the inner chamber 23 of the heating body 2 to a certain extent.

In one embodiment of the present disclosure, referring to fig. 5, the steam generator further comprises a temperature detecting element 4. The temperature detecting element 4 is located in the inner cavity 23 of the sleeve 22 and is configured for detecting the temperature of the heat conducting rod 26. The temperature detecting element 4 includes a positive electrode wire 41 and a negative electrode wire 42 as the lead wires 21, the positive electrode wire 41 and the negative electrode wire 42 being configured to pass through the first support 24, the sealing plug 31, and the second support 25 in this order. The positive electrode wire 41 and the negative electrode wire 42 are matched with the first support 24, the sealing plug 31 and the second support 25 in the same manner as the heating wire 262, and the disclosure will not be described in detail here.

As shown in fig. 4, a temperature detecting element 4 is provided adjacent to the end of the second end of the heating body 2, and the temperature detecting element 4 may be a thermocouple detecting element or another kind of detecting element. When the temperature detecting element is a thermocouple detecting element, the measuring point of the thermocouple detecting element is disposed inside the second end of the adjacent heating body.

Specifically, the temperature measuring component can be a thermocouple detecting element or a thermistor detecting element. When the temperature measuring component is a thermocouple detecting element, the connection point of the two wires 21 is the measuring point 43 of the thermocouple detecting element. When the temperature measuring component is a thermistor detecting element, the position of the thermistor is the measuring point 43 of the thermistor detecting element. After the temperature of the high temperature region is obtained, the steam generator of the present disclosure can adjust the heating power of the heating body 2, thereby ensuring that the heating body 2 can normally heat water into steam.

As shown in fig. 4 and 5, the measurement point 43 of the thermocouple detecting element is a connection point of the positive electrode wire 41 and the negative electrode wire 42, and the connection point is in a range of 5.5 to 10.5mm from the end face of the second end of the heat conducting rod 26. This is because the heating body 2 is heated up as a whole, and the temperature at both end positions thereof is lower than the temperature at the middle position thereof. When the water flow covers one end area of the heating body 2 in the axial direction and the other end area is not covered by the water flow, the temperature of the heating body 2 at the position is lowered under the action of the water, and the end area far away from the water keeps the temperature of the heating body 2 as being not covered by the water flow, and the farther the distance from the water flow is, the smaller the temperature of the heating body 2 is affected by the water flow. Under the dimensional parameters of the heating body 2 of the present disclosure, the measurement point is set in the range of 5.5 to 10.5mm from the end face of the first end of the heat conducting rod 26, better reflecting the highest temperature of the heating body 2 when in operation. In another embodiment of the present disclosure, referring to fig. 6 and 7, the sealing member is a sealing sleeve 32, one end of the sealing sleeve 32 is configured to be fixed to an outer wall of the first end of the housing 1, and the other end is configured to be fixed to the lead 21. In this embodiment, the first end of the heating body 2 can be completely wrapped by sleeving the sealing sleeve 32 on the lead 21 and the shell 1, so as to achieve the purpose of sealing the first end of the heating body 2 by the sealing sleeve 32 and prevent external water or moisture from entering the inner cavity 23 of the heating body 2 from the sealing sleeve.

In one embodiment of the present disclosure, referring to fig. 7, in order to further improve the sealing performance of the sealing sleeve 32 and to fix the sealing sleeve 32 with the housing 1, one end of the sealing sleeve 32 is sleeved on the outer wall of the housing 1 and is configured to be fixed by the first fixing portion 321. The other end of the sealing sleeve 32 is sleeved on the wire 21 and is configured to be fixed by the second fixing portion 322. Namely, the sealing sleeve 32 is provided with a hollow cavity, the wire 21 passes through the hollow cavity, one end of the sealing sleeve 32 is sleeved at the end position of the first end of the shell 1, and then the sealing sleeve 32 is fixed by adopting the first fixing part 321 so as to ensure the sealing performance between the sealing sleeve 32 and the shell 1; the other end of the sealing sleeve 32 is sleeved on the outer side of the wire 21, and then is fixed by adopting a second fixing part 322, so that the sealing performance between the sealing sleeve 32 and the wire 21 is ensured.

In order to further enhance the sealing performance of the sealing boot 32 in a specific embodiment of the present disclosure, and with continued reference to fig. 7, one end of the sealing boot 32 is sized to fit the dimensions of the outer wall of the housing 1 and the other end is sized to fit the dimensions of the lead 21. The first end of the heating body 2 can be completely sealed through the sealing sleeve 32, and the moving or gaps of the first fixing portion 321 and the second fixing portion 322 can be effectively avoided due to the adaptive size, so that the sealing effect is affected.

In this embodiment, a groove is disposed on the housing 1 corresponding to the first fixing portion 321, and the size of the groove is adapted to the first fixing portion 321. When the first fixing portion 321 is matched with the sealing sleeve 32 to enable the sealing sleeve to be fixed on the shell 1 in a sealing mode, the first fixing portion 321 can be just installed in a groove on the shell 1. The first fixing portion 321 is clamped in the groove on the shell 1, so that the displacement between the first fixing portion 321 and the shell 1 can be effectively prevented from affecting the sealing effect, the mounting position of the first fixing portion 321 is limited, and the sealing performance of the sealing sleeve 32 is improved. Likewise, the dimensions of the second fastening portion 322 are adapted to the dimensions of the wire 21, so that the second fastening portion 322 can be sealed together with the wire 21, effectively preventing external water or moisture from entering the interior 23 of the heating body 2.

In one embodiment of the present disclosure, the first fixing portion 321 and the second fixing portion 322 may be a ribbon or a wire harness, or may be a clip or other components that are well known to those skilled in the art and can fix the sealing sleeve 32, which will not be described in detail herein.

Of course, in order to further improve the sealing effect of the sealing member, a sealing cap 31 may be provided in the inner cavity of the heating body 2, and a sealing sleeve 32 covering the heating body 2 may be provided in the area of the steam generator adjacent to the first end. The sealing plug 31 and the sealing sleeve 32 simultaneously act on the heating body 2, and the sealing performance of the two can be further improved.

The disclosure also provides an intelligent device, which can be a device needing to spray steam, such as a steam generator, a wireless steam floor washing machine, a wireless steam mop or a wireless fumigation instrument, and the like, and is provided with the steam generator. The function of the individual structures of the steam generator is referred to above and is not illustrated here.

In one embodiment of the present disclosure, the smart device is a cleaning device, and referring to fig. 1, the cleaning device includes a body 51, and a floor brush assembly 52 disposed at the bottom of the body 51. The floor brush assembly 52 includes a floor brush housing 53 and a floor brush 54 coupled to the floor brush housing 53 and configured for cleaning a work surface. The steam generator is disposed in the cavity of the floor brush housing 53 and is configured to provide steam to the work surface. Of course, it will be apparent to those skilled in the art that the steam generator described above may be applied not only to cleaning devices, but also to eye fumigators, garment hangers or other devices known to those skilled in the art, and the disclosure will not be described in detail herein.
