In the case of the cleaning device 10, particularly, the steam floor-washing machine, the device body 11 may include a floor brush 111 and a hand-held portion 112 for cleaning, the floor brush 111 is rotatably connected to the hand-held portion 112, and a user can move the floor brush 111 by holding the hand-held portion 112, so as to perform a cleaning operation through the floor brush 111.

The cleaning device 10 further comprises a cleaning assembly 13. The cleaning unit 13 is provided in the apparatus main body 11. Further, the cleaning assembly 13 may be mounted to the floor brush portion 111.

The heating unit 20 is an element for heating fluid in the apparatus body 11. The low-temperature liquid fluid is input into the heating assembly 20 and is heated by the heating assembly 20 to form high-temperature liquid fluid or gaseous fluid, and the high-temperature liquid fluid or gaseous fluid can soften stains and play roles in disinfection, sterilization and the like so as to assist the cleaning assembly 13 in cleaning.

Optionally, the fluid used in this embodiment may be water, which has the advantages of easy availability and low cost. Of course, in other embodiments of the present application, the applied fluid may also be other media, such as a mixed liquid of water and cleaning liquid, and the like, and is not limited herein. In the embodiment, the temperature of the fluid is controlled by the heating assembly 20, so that the heating assembly 20 can output high-temperature liquid fluid and gaseous fluid as required.

The floor brush portion 111 includes a floor brush base 111a and a cover 141 detachably connected to the floor brush base 111a. Further, the output connector 17, the cleaning assembly 13 and the heating assembly 20 can be mounted on the floor brush base 111a. The fluid outlet 143 is provided in the cover 141. The cover 141 is detachable from the floor brush base 111a to expose the output connector 17. The cover 141 is connected to the heating assembly 20, and the fluid heated by the heating assembly 20 is output through the cover 141 to assist the cleaning assembly 13 in cleaning.

It should be noted that the high-temperature gaseous fluid (i.e., steam) generated by heating the heating assembly 20 can be output onto the surface to be cleaned, the high-temperature gaseous fluid can soften stains and perform the functions of disinfection and sterilization, etc., and then the cleaning assembly 13 can easily clean the stains on the surface to be cleaned and perform the functions of disinfection and sterilization on the surface to be cleaned. The fluid outlet 143 may be located at a front side of the cleaning assembly 13, and the fluid outlet 143 outputs the high-temperature gaseous fluid obliquely at a certain pressure, that is, the output high-temperature gaseous fluid is in an oblique jet shape. The cover 141 sprays high-temperature gaseous fluid on the surface to be cleaned, and after the stain on the surface to be cleaned is softened, the cleaning assembly 13 removes the softened stain along with the movement of the brushing portion 111 pushed by the user.

Further, referring to fig. 4, the cover 141 is further provided with a cover passage (not shown) and a cover inlet 142. The cover inlet 142 communicates with the fluid outlet 143 through a cover passage. Fluid is input into the cover channel from the cover inlet 142 and output through the fluid outlet 143. Specifically, the fluid output from the heating assembly 20 is input into the cover channel through the cover inlet 142 of the cover 141, and then output through the fluid outlet 143, and the fluid output from the fluid outlet 143 is used to assist the cleaning assembly 13 in cleaning.

The output connector 17 of the device body 11 of the present embodiment communicates with the fluid outlet 143. The heating assembly 20 is connected to the output connector 17, and the cover 141 is connected to the output connector 17 through the cover inlet 142. Fluid output from the heating assembly 20 is input to the cover inlet 142 through the output connector 17 and output from the fluid outlet 143.

Further, the cover 141 is detachably connected to the floor brush base 111a. Specifically, the cover 141 is detachably connected to the floor brush base 111a through the sliding lock 144. When the cover 141 is assembled to the floor brush base 111a, the cover 141 is coupled to the heating unit 20. When the cover 141 is detached from the floor brush base 111a, the cover 141 is detached from the heating element 20.

For example, fig. 3 exemplarily shows that the cover 141 is detachably connected to the floor brush base 111a through two sets of sliding latches 144. The two sets of sliding latches 144 are pressed in the left and right directions indicated by arrows in fig. 3, so that the two sets of sliding latches 144 move towards each other, and the cover 141 is detached. Alternatively, fig. 5 exemplarily shows that the cover 141 is detachably connected to the floor brush base 111a through a set of sliding latches 144. The cover 141 is removed by pressing the slide latch 144 in the direction of the arrow shown in fig. 5. It should be noted that the working principle of the sliding lock 144 is understood by those skilled in the art, and will not be described herein.

Of course, in other embodiments of the present application, the detachable connection between the cover 141 and the floor brush base 111a is not limited to the above-mentioned sliding lock 144, and for example, the detachable connection between the cover 141 and the floor brush base 111a can be achieved by magnetic attraction, a snap, and the like, which is not limited herein.

In one embodiment, the cleaning device 10 further includes a liquid supply chamber 12, the liquid supply chamber 12 is in communication with the heating assembly 20, the heating assembly 20 is configured to heat the fluid provided by the liquid supply chamber 12, and the fluid heated by the heating assembly 20 is output to the surface to be cleaned through the fluid outlet 143.

Alternatively, in the present embodiment, the high-temperature gaseous fluid (i.e., steam) generated by heating by the heating assembly 20 can be output onto the surface to be cleaned, the high-temperature gaseous fluid can soften stains and perform the functions of disinfection and sterilization, etc., and then the cleaning assembly 13 can easily clean the stains on the surface to be cleaned and perform the functions of disinfection and sterilization on the surface to be cleaned.

In one embodiment, the cleaning device 10 further includes a liquid flow channel (not shown), and the device body 11 is further provided with a liquid outlet (not shown), one end of the liquid flow channel is communicated with the liquid supply chamber 12, and the other end of the liquid flow channel is communicated with the liquid outlet, and the liquid outlet is used for outputting the fluid supplied from the liquid supply chamber 12 to the cleaning assembly 13. The liquid supply chamber 12 supplies fluid to the cleaning assembly 13 to wet the cleaning assembly 13, which is beneficial to improve the cleaning efficiency of the cleaning assembly 13 for dry and wet garbage. In other embodiments, the heating assembly 20 may be disposed on the liquid flow channel, so that the fluid heated by the heating assembly 20 is output to the cleaning assembly 13 through the liquid outlet.

It will be appreciated that the cleaning device 10 of the embodiment of the present application includes at least two flow paths, which we refer to as a first flow path and a second flow path. The liquid supply chamber 12 is connected to the first flow path and the second flow path, respectively, for supplying liquid fluid to the first flow path and the second flow path. The flow path in which the heating element 20 is located is a first flow path, i.e. the heating element 20 is disposed on the first flow path, and the fluid outlet 143 is in communication with the first flow path and is configured to output steam to the surface to be cleaned. The liquid flow path is a second flow path, and the liquid outlet is communicated with the second flow path and is used for supplying liquid fluid to the cleaning assembly 13.

It should be noted that in other embodiments, the fluid heated by the heating assembly 20 can also provide fluid, such as steam, to the cleaning assembly 13 through the fluid outlet 143, and in this embodiment, the fluid outlet 143 can be disposed toward the cleaning assembly 13 or a drainage structure can be disposed to guide the fluid output from the fluid outlet 143 to the cleaning assembly 13. Of course, in other embodiments, the fluid heated by the heating assembly 20 may be output to both the surface to be cleaned and the cleaning assembly 13.

Referring to fig. 6a-6b, fig. 6a-6b are schematic structural views of an embodiment of the cleaning system of the present application.

In one embodiment, the cleaning system applied to the cleaning device 10 further includes a function expanding device 30. The output connector 17 can be selectively connected to the expansion device 30 or the fluid outlet 143. The fluid heated by the heating assembly 20 flows to the fluid outlet 143 through the output connector 17 and is then output to the cleaning assembly 13 and/or the surface to be cleaned. Alternatively, the fluid heated by the heating module 20 is output to the function expanding device 30 through the output connector 17. That is, when the output connector 17 is communicated with the fluid outlet 143, the fluid heated by the heating module 20 may be output through the fluid outlet 143, and when the output connector 17 is communicated with the function expanding device 30, the fluid heated by the heating module 20 may be output through the function expanding device 30. The functional expansion device 30 utilizes the heated fluid to perform more functions, including but not limited to cleaning functions.

In other words, in the case where the cleaning function is realized by the cleaning device 10 in the cleaning system of the present embodiment, the function of the cleaning device 10 is also expanded by the function expanding device 30, so that the cleaning device 10 not only has the cleaning function, and thus the function of the cleaning device 10 can be enriched.

Optionally, the functionality extension device 30 comprises at least one of a garment steamer and a steam iron. In the embodiment, on the basis of the cleaning device 10, the function expanding device 30 expands the cleaning device 10 to have more functions, such as ironing clothes and sterilizing sofas and beds.

Further, considering that the user generally does not use the cleaning assembly 13 and the function expanding device 30 at the same time, the present embodiment is preferred that the cover 141 and the function expanding device 30 are alternatively connected with the heating assembly 20, i.e., the function expanding device 30 is allowed to be connected with the heating assembly 20 after the cover 141 is detached. In other words, the function expanding means 30 and the cover 141 share the output connector 17, which simplifies the structure of the cleaning apparatus 10, and when the cleaning apparatus 10 performs a cleaning operation, the cover 141 is connected to the floor brush base 111a so that the output connector 17 communicates with the fluid outlet 143, and when the cleaning apparatus 10 needs to supply fluid to the function expanding means 30, the cover 141 is detached so that the output connector 17 is exposed so that the output connector 17 can be connected to the function expanding means 30.

In other embodiments, the cleaning device 10 may further include a switching mechanism (not shown) by which the heating assembly 20 communicates with one of the output fitting 17 and the fluid outlet 143. Alternatively, the switching mechanism may be a valve, and the switching mechanism can selectively communicate the heating assembly 20 with one of the output connector 17 and the fluid outlet 143, so that the fluid heated by the heating assembly 20 is output to the cleaning assembly 13 and/or the surface to be cleaned through the fluid outlet 143, or the fluid heated by the heating assembly 20 is output to the function expanding device 30 through the output connector 17.

In this embodiment, the cleaning device 10 further includes an output line 161, as shown in FIG. 2. The heating assembly 20 is connected to the output connector 17 through an output pipeline 161, and the fluid heated by the heating assembly 20 is delivered to the output connector 17 through the output pipeline 161 and is output from the output connector 17.

Further, the cleaning apparatus 10 further includes a position detection sensor (not shown). The in-place detection sensor is disposed at a position of the output connector 17, and is configured to detect whether the output connector 17 is connected to the cover 141 or the function expanding device 30, so that when the in-place detection sensor detects that the output connector 17 is connected to the cover 141 or the function expanding device 30, the heating assembly 20 heats the fluid.

Alternatively, the position detection sensor may be a hall sensor or the like, which is not limited herein.

In one embodiment, the cleaning device 10 is designed to be cordless, i.e., the cleaning device 10 has a rechargeable power source, and when the cleaning device 10 is in operation, the power source of the cleaning device 10 provides power to facilitate the cleaning operation. Specifically, the cleaning device 10 also includes a battery (not shown). The battery is electrically connected to the heating assembly 20 for providing electrical energy to the heating assembly 20 such that the heating assembly 20 is capable of heating the fluid.

The battery is a rechargeable battery. When the user does not use the cleaning device 10, the battery can be charged, so that when the user uses the cleaning device 10, the battery can independently provide the electric energy required by the operation of the cleaning device 10, the conventional power cord can be prevented from binding the movement of the cleaning device 10, and the cleaning operation can be conveniently performed by the user.

Referring to fig. 7, fig. 7 is a schematic structural diagram of another embodiment of the cleaning system of the present application.

In an embodiment, the cleaning system further comprises a fluid transit device 31. When the function expanding device 30 is connected to the heating module 20, the function expanding device 30 is specifically connected to the heating module 20 through the fluid transfer device 31. The fluid transfer device 31 plays a transfer role, and the fluid output by the heating assembly 20 is collected in the fluid transfer device 31 and then output to the function expansion device 30 through the fluid transfer device 31.

Through the manner, when the user uses the function expanding device 30, the user does not need to move the cleaning device 10, but carries the function expanding device 30 and the fluid transfer device 31 instead, and the high-temperature fluid generated by the cleaning device 10 can be used for a long distance by using the fluid transfer device 31 as a transfer.

Further, a pressurizing member (not shown) may be provided in the fluid relay device 31. The pressurizing piece is used for pressurizing the fluid in the fluid transfer device 31 and then outputting the pressurized fluid to the function expanding device 30, so that the fluid pressure can be ensured to meet the use requirement of the function expanding device 30, and further the function of the function expanding device 30 can be realized.

Alternatively, the pressurizing member may be a pressurizing pump or a pressurizing impeller, etc., and is not limited herein.

Referring to fig. 8 and 9 together, fig. 8 isbase:Sub>A schematic structural view ofbase:Sub>A first embodiment of the heating element of the present application, and fig. 9 isbase:Sub>A schematic sectional structural view inbase:Sub>A directionbase:Sub>A-base:Sub>A of the heating element shown in fig. 8.

In one embodiment, the device body 11 has a lower side 11a and an upper side 11b disposed opposite to each other, as shown in fig. 3. The cleaning assembly 13 is used to clean the surface to be cleaned at the underside 11a. In other words, the cleaning device 10 of the present embodiment is generally used for cleaning the surface to be cleaned at the bottom of the cleaning device 10, i.e., the bottom of the device body 11 faces the lower side 11a, and the top of the device body 11 faces the upper side 11b.

At least two heating chambers 21 are provided inside the heating module 20, and the fluid inputted into the heating module 20 is heated by passing through the heating chambers 21. Wherein, the at least two heating cavities 21 are sequentially arranged from top to bottom and are sequentially communicated, that is, the adjacent heating cavities 21 are communicated with each other.

The cleaning device 10 also includes a heating assembly inlet 18. The heating module inlet 18 is disposed in the heating module 20, and the heating module inlet 18 communicates with the heating chamber 21 at the lower side 11a. In other words, the heating assembly inlet 18 communicates with the heating cavity 21 near the bottom of the heating assembly 20.

The cleaning device 10 also includes a heating assembly outlet 15. The heating element outlet 15 is provided in the heating element 20, and the heating element outlet 15 communicates with the heating chamber 21 located on the upper side 11b. In other words, the heating assembly outlet 15 communicates with the heating chamber 21 near the top of the heating assembly 20.

The fluid is input from the heating assembly inlet 18, passes through the at least two heating chambers 21 in sequence in a direction from the lower side 11a towards the upper side 11b, and is output from the heating assembly outlet 15. In other words, the heating chamber 21 communicating with the heating module inlet 18 is located below the heating chamber 21 communicating with the heating module outlet 15, and the fluid is input from the bottom of the heating module 20 and is delivered upward to the heating module outlet 15 for output. The flow direction of the fluid in the at least two heating chambers 21 of the heating assembly 20 is exemplarily illustrated in fig. 9.

Since the density of the heated fluid decreases, the fluid heated by the heating assembly 20 has a tendency to flow upward, and the fluid is fed from the bottom of the heating assembly 20 and is conveyed upward to the outlet 15 of the heating assembly. Especially when the heating assembly 20 generates a gaseous fluid, which flows upwards without passing through the fluid output while still in a liquid state, it is possible to avoid as much as possible mixing of the gaseous fluid and the liquid fluid, facilitating control of the state of the fluid output by the cleaning device 10, for example facilitating generation of dry steam and the like.

In the prior art, the fluid is fed from the top of the heating assembly and delivered downward. Since the density of the heated fluid is reduced and the fluid heated by the heating assembly tends to flow upward, the fluid flow path of the prior art will inevitably cause the gaseous fluid and the liquid fluid to mix, and it is inconvenient to control the state of the fluid output from the cleaning device. In other words, the design of the fluid flow path inside the heating assembly of the present embodiment matches the upward flowing tendency of the heated fluid, which can facilitate the control of the state of the fluid output by the cleaning device.

In an exemplary embodiment, the volume of heating cavity 21 in communication with heating assembly inlet 18 is equal to the volume of heating cavity 21 in communication with heating assembly outlet 15. Preferably, the volumes of the heating chambers 21 are equal. Therefore, the heat provided by each heating cavity 21 can be conveniently controlled, and the heating assembly 20 can be ensured to output high-temperature liquid fluid or gaseous fluid as required.

For example, fig. 9 shows that the heating element 20 includes two heating cavities 21, i.e., the heating element 20 includes a heating cavity M and a heating cavity N. The heating assembly inlet 18 is communicated with the heating cavity M, and the heating assembly outlet 15 is communicated with the heating cavity N. Wherein, the volume of the heating cavity M is equal to that of the heating cavity N.

In another exemplary embodiment, the volume of heating cavity 21 in communication with heating assembly inlet 18 is greater than the volume of heating cavity 21 in communication with heating assembly outlet 15. In other words, the volume of the heating cavity 21 near the bottom of the heating assembly 20 is greater than the volume of the heating cavity 21 near the top of the heating assembly 20. In this way, under the condition of a constant heating power, the fluid passes through the heating cavity 21 close to the upper side 11b, so that the temperature of the fluid can be increased, and the heating assembly 20 can output the fluid in a required state more efficiently.

For example, based on the example shown in fig. 9 in which the heating element 20 includes the heating chamber M and the heating chamber N, the volume of the heating chamber M is larger than that of the heating chamber N. In other words, the volume of the heating chamber N is small. Under the condition of certain heating power, the fluid passes through the heating cavity N, and the temperature rising speed of the fluid can be accelerated.

Referring to fig. 10 and 11 together, fig. 10 is a schematic structural view of an embodiment of a heating chamber of the present application, and fig. 11 is a schematic structural view of another embodiment of the heating chamber of the present application.

In an embodiment, each heating cavity 21 has a first fluid channel 213 and a second fluid channel 214 disposed therein. The first fluid passage 213 and the second fluid passage 214 are communicated with the inlet and the outlet of the heating chamber 21, respectively. The heating cavity 21 is communicated with the outlet of the upper stage heating cavity 21 through the inlet thereof, and the heating cavity 21 is communicated with the inlet of the lower stage heating cavity 21 through the outlet thereof.

In the direction from the lower side 11a to the upper side 11b, for the heating cavity 21 at the bottom of the heating assembly 20, the heating assembly inlet 18 is an inlet of the heating cavity 21, and a passage of the heating cavity 21 communicating with the next stage heating cavity 21 is an outlet of the heating cavity 21; for the heating cavity 21 in the middle of the heating component 20, the inlet is a passage through which the heating cavity 21 communicates with the heating cavity 21 of the previous stage, and the outlet is a passage through which the heating cavity 21 communicates with the heating cavity 21 of the next stage; for the heating cavity 21 at the top of the heating assembly 20, the inlet is a passage through which the heating cavity 21 communicates with the heating cavity 21 of the previous stage, and the outlet is the heating assembly outlet 15.

For example, based on the example shown in fig. 9 in which the heating element 20 includes a heating cavity M and a heating cavity N, the heating element inlet 18 is an inlet of the heating cavity M, the heating element outlet 15 is an outlet of the heating cavity N, and the outlet of the heating cavity M is communicated with the inlet of the heating cavity N.

The first fluid channel 213 is located outside the second fluid channel 214, and the fluid inputted from the inlet of the heating chamber 21 is respectively transmitted to the outlet of the heating chamber 21 through the first fluid channel 213 and the second fluid channel 214. The embodiment increases the heating area of the fluid in the heating cavity 21 through the first fluid channel 213 and the second fluid channel 214, which is beneficial to improving the heating efficiency of the fluid.

Furthermore, the two opposite sides of the second fluid channel 214 are respectively provided with the first fluid channel 213, the fluid input from the inlet of the heating cavity 21 is divided into at least three paths, one path is conveyed through the second fluid channel 214, and the remaining two paths are conveyed through the first fluid channels 213 on the two sides of the second fluid channel 214, which is further beneficial to improving the heating efficiency of the fluid.

And, the length of the first fluid channel 213 and the length of the second fluid channel 214 are both greater than the linear distance between the inlet and the outlet of the heating chamber 21. In other words, the first fluid channel 213 and the second fluid channel 214 both extend from the inlet to the outlet in a meandering manner, which further increases the heated area of the fluid in the heating cavity 21, and is beneficial to improving the heating efficiency of the fluid.

For example, a plurality of guiding structures 215 may be disposed in the heating cavity 21, and the plurality of guiding structures 215 enclose to form the first fluid channel 213 and the second fluid channel 214. Based on the example of the heating assembly 20 shown in fig. 9 including the heating chamber M and the heating chamber N, the first fluid channel 213 and the second fluid channel 214 and the fluid flowing direction in the heating chamber M are shown in fig. 10, and the first fluid channel 213 and the second fluid channel 214 and the fluid flowing direction in the heating chamber N are shown in fig. 11.

Referring to fig. 12, fig. 12 is a schematic cross-sectional view of a heating element according to a second embodiment of the present invention.

In an embodiment, at least three heating cavities 21 located at the bottom of the heating module 20 are disposed inside the heating module 20 and are communicated with the heating module inlet 18, and the other heating cavities 21 are communicated with the heating module outlet 15.

In other words, each stage of the heating cavity 21 of the present embodiment may be provided with an outlet to allow different stages of the heating cavity 21 to output different states of fluid, such as liquid fluid and gaseous fluid at different temperatures.

Please continue to refer to fig. 9. In one embodiment, the lower side 11a and the upper side 11b of the apparatus body 11 are oppositely disposed in a predetermined direction (as indicated by an arrow X in fig. 3 and 9, the same applies hereinafter). Further, the preset direction may be a height direction of the apparatus body 11. The bottom of the heating assembly inlet 18 is higher than the bottom of the heating chamber 21 that communicates with the heating assembly inlet 18.

Specifically, the heating assembly inlet 18 is provided with a passage 181, and the passage 181 is communicated with the heating cavity 21. Wherein the bottom of the channel 181 is higher than the bottom of the heating chamber 21 communicating with the heating assembly inlet 18.

The heating assembly 20 is provided with a heating element 22 for heating the fluid in the heating chamber 21. Preferably, the heating member 22 may be a heating element such as a heating pipe. The bottom of the heating element inlet 18 and the bottom of the heating cavity 21 communicated with the heating element inlet 18 have a height difference, so that the scale is preferentially deposited on the bottom of the heating cavity 21 communicated with the heating element inlet 18, the influence of the scale on the heating efficiency of the heating element 22 can be reduced, and the deposition time of the scale can be prolonged.

And, the corner of fluid passage adopts big curved surface, big fillet design in the heating cavity 21, is favorable to the fluid to smoothly pass through, reduces the sedimentary risk of incrustation scale in the corner, can slow down the incrustation scale equally and influence the heating efficiency of heating member 22, prolongs the settling time of incrustation scale. In addition, the heating member 22 is located between two adjacent heating chambers 21, and the scale deposited on the bottom of the heating chambers 21 has less influence on the heating efficiency of the heating member 22.

For example, based on the example shown in fig. 9 in which the heating element 20 includes the heating cavity M and the heating cavity N, the bottom of the inlet passage 181 and the bottom of the heating cavity M are spaced from each other in a predetermined direction, that is, the bottom of the inlet passage 181 and the bottom of the heating cavity M have a height difference. The heating element 22 is located between the heating chamber M and the heating chamber N.

Referring also to fig. 13, fig. 13 is an exploded view of the heating element of fig. 8.

In one embodiment, the heating assembly 20 includes a heating body 23 and insulation 24. The heating body 23 is provided inside with the above-mentioned at least two heating chambers 21. The heat insulating member 24 is attached to the outer side of the heating body 23, the heat insulating member 24 is used for reducing heat loss of the heating body 23, and the heating body 23 contacts other components of the cleaning device 10 through the heat insulating member 24 to reduce heat loss of the heating body 23, so as to alleviate the condensation of the fluid output by the heating assembly 20, and prevent the high temperature of the heating body 23 from affecting the structural stability of other components.

Fig. 13 exemplarily shows that the top and bottom of the heating body 23 are respectively provided with the heat insulator 24. Alternatively, the thermal insulation member 24 may be a thermal insulation silicone rubber or the like, which is not limited herein.

In an embodiment, the heating main body 23 includes the heating base 231, sealing covers (including a first sealing cover 2321 and a second sealing cover 2322, etc. described below), and the sealing member 233. The at least two heating cavities 21 are disposed inside the heating seat 231. The sealing member 233 is disposed between the heating base 231 and the sealing cover, and the sealing cover presses the sealing member 233 onto the heating base 231, so that the heating chamber 21 is sealed. The heat insulation member 24 is disposed on a side of the sealing cover away from the heating chamber 21.

For example, based on the example that the heating element 20 includes the heating cavity M and the heating cavity N as shown in fig. 9, the heating body 23 includes a first sealing cover 2321 and a second sealing cover 2322, and the first sealing cover 2321 and the second sealing cover 2322 are respectively located at the top and the bottom of the heating holder body 231. The first sealing cover 2321 presses the sealing member 233 onto the heating base 231, so that the heating cavity M forms a seal. The second sealing cover 2322 presses the sealing member 233 onto the heating base 231, so that the heating cavity N forms a seal.

In one embodiment, the cleaning device 10 further includes a temperature controlled switch 41. The temperature controlled switch 41 is connected in series with the heating assembly 20. Specifically, the temperature controlled switch 41 is electrically connected to the heating member 22 in the heating assembly 20. The heating member 22 is connected in series to an external power source through a temperature control switch 41. Wherein the temperature controlled switch 41 is used to switch off the heating element 22 when the temperature of the heating chamber 21 exceeds a temperature threshold (i.e. a second temperature threshold).

The second temperature threshold is defined as the maximum temperature allowed for safe operation of the heating assembly 20. When the temperature of the heating cavity 21 exceeds the second temperature threshold, it is described that the temperature of the current heating cavity 21 is too high, and the safety problem is easy to occur, so that the temperature controlled switch 41 is opened, and further the heating member 22 is opened, which is beneficial to improving the safety performance of the cleaning device 10 of the embodiment.

For example, the temperature control switch 41 may be a switch using a bimetal as a temperature sensing element. When the electric appliance works normally, the bimetallic strip is in a free state, and the contact is in a closed/open state. When the temperature rises to a threshold value, the bimetal element is heated to generate internal stress to act rapidly, the contact is opened/closed, and the circuit is cut off/connected, so that the thermal protection effect is achieved. When the temperature drops to the reset temperature, the contact is automatically closed/opened, and the normal working state is recovered.

Further, the cleaning device 10 further includes a controller (not shown) and a thermistor 42. The thermistor 42 is connected in series with the temperature control switch 41 and the heating member 22, respectively. The controller is electrically connected to the heating elements 22 and the thermistor 42 of the heating assembly 20, respectively. The thermistor 42 is used for feeding back the temperature of the heating assembly 20 to the controller in real time, so that the temperature of the heating assembly 20 is controlled by the controller, and the temperature of the heating assembly 20 is kept lower than the second temperature threshold, which is beneficial to improving the safety performance of the cleaning device 10 of the embodiment.

Alternatively, the thermistor 42 may be a Positive temperature Coefficient thermistor (PTC), a negative temperature Coefficient thermistor (NTC), or the like.

In an alternative embodiment, the cleaning device 10 also includes a fuse (not shown). The fuse is connected in series with the temperature controlled switch 41 and the heating member 22 of the heating assembly 20, respectively. When the current through the fuse exceeds the current threshold, the fuse forms an open circuit, causing heating element 22 to form an open circuit.

The current threshold is defined as the maximum current allowed for safe operation of heating element 22. When the current passing through the fuse exceeds the current threshold, it is shown that the current passing through the heating element 22 is too large, and the safety problem is easy to occur, so that the fuse is fused at the moment to form an open circuit, and further the heating element 22 forms an open circuit, which is beneficial to improving the safety performance of the cleaning device 10 in the embodiment.

Referring to fig. 14, fig. 14 is a schematic structural diagram of a heating element according to a third embodiment of the present application.

In one embodiment, the cleaning device 10 further includes an input line 162. The input line 162 is connected to the heating assembly 20 for inputting fluid into the heating assembly 20. Further, the input line 162 is connected to the heating module 20 through the heating module inlet, and the fluid in the input line 162 is input into the heating module 20 through the heating module inlet. The input line 162 is connected to the liquid supply chamber described above, and the liquid supply chamber is used to input liquid fluid to the input line 162.

The cleaning device 10 further comprises an output line 161. The output line 161 is connected to the heating assembly 20, and the fluid in the heating assembly 20 is output through the output line 161. Further, the output line 161 is connected to the heating module 20 through the heating module outlet, and the fluid in the heating module 20 is output to the output line 161 through the heating module outlet and then output through the output line 161. The outlet line 161 is also in communication with the fluid outlet described above.

The cleaning device 10 further comprises a first sensor 51. The first sensor 51 is disposed in the output line 161 for detecting the fluid in the output line 161.

The cleaning device 10 also includes a controller (not shown). The controller is configured to determine whether the amount of fluid in the output line 161 is lower than a first preset value according to a detection result of the first sensor 51. When the amount of fluid passing through the output line 161 is lower than the first preset value, it is determined that no fluid passes through the output line 161, i.e., the heating assembly 20 cannot output fluid due to a failure, and the heating assembly 20 needs to be stopped for maintenance.

In other words, in the present embodiment, the first sensor 51 detects whether the output pipeline 161 outputs the fluid normally, so as to timely reflect the situation that the output pipeline 161 does not output the fluid normally, and further, by timely controlling the heating element 20 to stop the heating operation, the dangerous situation can be avoided, especially, the dangerous situation that the inside of the heating element 20 is blocked by the scale after the heating element 20 operates for a long time, and the dangerous situation that the fluid in the heating element 20 is insufficient and is burned, etc. are avoided, so that the safety performance of the cleaning system can be improved.

Further, the control is also electrically connected to the heating assembly 20. Specifically, the controller is electrically connected to the heating element 22 of the heating assembly 20. When the first sensor 51 detects that the amount of fluid passing through the output line 161 is below a first preset value, the controller controls the heating assembly 20 to stop heating.

In one embodiment, the first sensor 51 may be a temperature sensor. Since the heated fluid causes the first sensor 51 to sense a higher temperature when there is fluid in the output line 161, and the first sensor 51 to sense a lower temperature when there is no fluid in the output line 161. Based on this, the first sensor 51 of the present embodiment can detect the fluid in the output line 161 by sensing the temperature of the output line 161.

Specifically, a first temperature threshold is defined, which is the lowest temperature of outlet line 161 when the amount of fluid passing through outlet line 161 is not less than a first preset value. When the temperature detected by the first sensor 51 is lower than a first temperature threshold, the controller determines that the amount of fluid in the output line 161 is lower than a first preset value; when the temperature detected by the first sensor 51 is not lower than the first temperature threshold, the controller determines that the amount of fluid in the output line 161 is not lower than the first preset value.

In an alternative embodiment, the first sensor 51 may also be a flow sensor, and the fluid in the output line 161 is detected by the first sensor 51 directly sensing the flow of the fluid passing through the output line 161.

Specifically, a first flow threshold is defined, which is the minimum flow of fluid in outlet line 161 when the amount of fluid passing through outlet line 161 is not less than a first preset value. When the flow detected by the first sensor 51 is lower than the first flow threshold, the controller determines that the amount of fluid in the output line 161 is lower than a first preset value; when the flow detected by the first sensor 51 is not lower than the first flow threshold, the controller determines that the amount of fluid in the output line 161 is not lower than the first preset value.

Furthermore, depending on the specific application of the cleaning device 10, there is usually a certain requirement on the flow rate of the fluid output by the cleaning device 10. In view of this, the first sensor 51 feeds back the flow rate of the fluid passing through the output line 161 to the controller in real time, and the controller adjusts the flow rate of the fluid in the input line 162 according to the flow rate detected by the first sensor 51, so as to realize the automatic control of the fluid heating operation of the whole cleaning device 10.

Referring to fig. 15, fig. 15 is a schematic structural diagram of an embodiment of an input pipeline and an output pipeline according to the present application.

In one embodiment, the cleaning device 10 further includes a second sensor 52. The second sensor 52 is disposed in the input line 162 for detecting the fluid in the input line 162, and the controller is configured to determine whether the amount of fluid in the input line 162 is lower than a first preset value according to the detection result of the second sensor 52. When the amount of fluid passing through inlet line 162 is below a first predetermined value, no fluid is deemed to be passing through inlet line 162.

The second sensor 52 may cooperate with the first sensor 51 for troubleshooting. Specifically, when the amount of fluid passing through the outlet line 161 is lower than the first preset value and the amount of fluid passing through the inlet line 162 is not lower than the first preset value, it indicates that the heating assembly 20 is in an abnormal state, i.e., that the heating assembly 20 is malfunctioning. When the amount of fluid passing through the input line 162 is lower than the first predetermined value, it indicates that the input line 162 and/or the fluid source connected thereto is in an abnormal state, i.e., the input line 162 and/or the fluid source connected thereto is failed.

Further, the second sensor 52 may also be a flow sensor, the second sensor 52 directly senses the flow of the fluid passing through the input line 162, and the controller determines whether the amount of the fluid passing through the input line 162 is lower than the first preset value according to the detection result of the second sensor 52.

Specifically, a second flow threshold is defined, which is the minimum flow of fluid in the inlet line 162 when the amount of fluid passing through the inlet line 162 is not less than the first preset value. When the flow rate detected by second sensor 52 is lower than the second flow rate threshold, second sensor 52 detects that the amount of fluid passing through inlet line 162 is lower than a first preset value; when the flow rate detected by the second sensor 52 is not lower than the second flow rate threshold, the second sensor 52 detects that the flow rate passing through the input line 162 is not lower than the first preset value.

The second sensor 52 feeds back the flow rate of the fluid passing through the input pipeline 162 to the controller in real time, and the controller adjusts the flow rate of the fluid in the input pipeline 162 according to the flow rate detected by the second sensor 52, so that the flow rate of the fluid in the input pipeline 162 meets the requirement, and further, the automatic control of the fluid heating operation of the whole cleaning device 10 is realized.
