Detailed Description

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. This application is capable of implementation in many different ways than those herein set forth and of similar import by those skilled in the art without departing from the spirit of this application and is therefore not limited to the specific implementations disclosed below.

A steam cleaning device 100 is provided in a first embodiment of the present application, and fig. 1 is a schematic structural diagram of the steam cleaning device 100 provided in the first embodiment of the present application.

Referring to fig. 1, a steam cleaning apparatus 100 according to a first embodiment of the present application includes: a liquid container 4, a steam generator 200 and an air jet module 5. Wherein, the liquid containing device 4 is used for containing liquid and conveying the liquid into the steam generating device 200; the steam generating device 200 is used for heating the liquid and forming steam; the formed steam is sprayed out by the air spraying assembly 5, so that the cleaned surface is cleaned.

In the embodiment, in order to realize that the liquid in the liquid containing device 4 is conveyed into the steam generating device 200 and the steam formed in the steam generating device 200 is conveyed to the air injection assembly 5 to be injected, a first pipeline 6 is arranged among the liquid containing device 4, the steam generating device 200 and the air injection assembly 5; specifically, the upstream of the first pipeline 6 is connected with the liquid containing device 4 and the steam generating device 200 for conveying liquid; downstream of the first conduit 6 is a connection between the steam generating device 200 and the air injection assembly 5 for the delivery of steam. Wherein, the liquid containing device 4 is provided with a valve, the valve is connected with the upstream of the first pipeline 6, the valve can control the liquid containing device 4 to be opened or closed, and the valve can be controlled to be opened or closed by a power switch (not shown) of the steam cleaning device 100, or can be controlled to be opened or closed according to the liquid pressure in the liquid containing device 4; still alternatively, a water pump 8 is disposed between the liquid container 4 and the steam generator 200, the water pump 8 is specifically located upstream of the first pipeline 6, and the power switch controls the water pump 8 to be turned on or off, so as to convey the liquid in the liquid container 4 to the steam generator 200. Because the pressure of the liquid pumped by the water pump 8 is higher, the speed of conveying the liquid into the steam generating device 200 can be increased, so that the steam generating device 200 is prevented from being burst due to the fact that no liquid enters and is heated for a long time.

In the present embodiment, the steam-based cleaning device 100 is to achieve that when the device is shut down, steam is no longer ejected from the air injection assembly 5; to improve the safety of the use of the steam cleaning device 100. Therefore, when the steam cleaning apparatus 100 is shut down, the downstream of the first pipe 6 may contain un-sprayed steam, and since the steam is in a high temperature and high pressure state, the pressure of the downstream of the first pipe 6 may be increased instantaneously, and if the steam is not delivered to other positions in time, the downstream of the first pipe 6 may be burst, thereby affecting the personal safety of a user. In order to avoid this disadvantage, the present embodiment is further provided with a second pipeline 7, the second pipeline 7 is connected with the first pipeline 6 through a switching device (not shown), and the second pipeline 7 is connected between the gas injection assembly 5 and the liquid containing device 4, so as to convey the steam to the liquid containing device 4 through the second pipeline 7 to form liquid again. Of course, the gas injection assembly 5 can also deliver the steam downstream of the first line 6 to the liquid holding device 4 through the second line 7 when the steam cleaning device 100 is not shut down. The second pipeline 7 plays a role in pressure relief, cyclic utilization of steam and liquid can be achieved, and the purpose of saving is achieved while safety performance is improved.

In order to realize that when the steam cleaning device 100 is shut down, the steam is not sprayed out from the air spraying assembly 5, the embodiment realizes the scheme from the root of the steam generation, namely the steam generation device 200. Specifically, as shown in fig. 1, 2 and 3, the steam generating device 200 includes a heating element 1, a heat-conducting liquid storage cavity 2 and a control on/off device 3; the control is closed/from the device 3 and is connected heat-generating body 1 and heat conduction stock solution cavity 2, through control closing/from the device 3, heat-generating body 1 can laminate or separate with heat conduction stock solution cavity 2. The heating body 1 is provided with a first contact part, the heat-conducting liquid storage cavity 2 is provided with a second contact part, and the first contact part is arranged towards the second contact part; the heating element 1 is connected with the heat-conducting liquid storage cavity 2 through the control on/off device 3, and the first contact part of the heating element 1 can be attached to or separated from the second contact part of the heat-conducting liquid storage cavity 2 through the control on/off device 3; when the liquid storage cavity is in a fit state, liquid in the heat conduction liquid storage cavity 2 is heated by the heating body 1 to form steam to be sprayed out; when the heating body 1 is in a separated state, the heat-conducting liquid storage cavity 2 is heated, the steam generation amount in the heat-conducting liquid storage cavity 2 is reduced, and therefore steam is stopped being sprayed out.

Further, in the present embodiment, as shown in fig. 2 and 3, the control engaging/disengaging means 3 includes a control switch 31 and an engaging/disengaging means 32; the control switch 31 is arranged on the heating element 1 or the heat-conducting liquid storage cavity 2 and is connected with the attaching/detaching device 32, and the attaching/detaching device 32 is arranged between the heating element 1 and the heat-conducting liquid storage cavity 2; the control switch 31 controls the attaching/detaching device 32 to adjust the interval between the first contact portion and the second contact portion. The attaching/detaching device 32 of the present embodiment includes at least one of the following structures: elastic structure, buckle structure, scissors fork structure and rotatory sleeve structure etc..

Specifically, taking an elastic structure as an example, the elastic structure of the embodiment may be a plurality of springs 9, and the springs 9 are dispersedly disposed between the first contact portion and the second contact portion, and are used for supporting and connecting the heating element 1 and the heat-conducting liquid storage cavity 2; wherein, one end of the spring 9 is connected to the first contact part, and the other end of the spring 9 is connected to the second contact part, and the distance between the first contact part and the second contact part is adjusted by adjusting the telescopic state of the spring 9. In this embodiment, when the heating element 1 and the heat conduction liquid storage cavity 2 need to be set to the attaching state, the following three ways can be implemented:

mode one, through the manual regulation mode, through pressing control switch 31 promptly, make the first contact site of heat-generating body 1 move towards the second contact site of heat conduction stock solution cavity 2, spring 9 is compressed to make first contact site and second contact site contact, and then realize heat-generating body 1 to the liquid heating in the heat conduction stock solution cavity 2.

In the second mode, by an automatic adjustment mode, that is, the power switch is turned on, a controller (not shown, for example, a microcontroller) provided on the steam cleaning device 100 sends an electric signal to the control switch 31, and a driving motor (not shown) and a push rod (not shown) in the control switch 31 start to operate to compress the spring 9; specifically, in this embodiment, the output end of the driving motor is connected to the connection end of the push rod, and the transmission end of the push rod is connected to one end of the spring 9 connected to the first contact portion; when control switch 31 received the signal of telecommunication, driving motor drove the catch bar and moves towards one side of spring 9 to make the thrust of the transmission end of catch bar act on spring 9, spring 9 is compressed, thereby makes first contact site and second contact site contact, and then realizes the liquid heating of heat-generating body 1 in to heat conduction stock solution cavity 2.

In a third mode, a controller (not shown, for example, a microcontroller) disposed on the steam cleaning device 100 sends a warning signal, such as a voice warning or an LED display warning lamp, to the control switch 31 through a manual and automatic combined adjustment mode, that is, the power switch is turned on. The user receives this warning signal, then in the time of predetermineeing, through pressing control switch 31, makes the first contact site of heat-generating body 1 remove towards the second contact site of heat conduction stock solution cavity 2, and spring 9 is compressed to make first contact site and second contact site contact, and then realize heat-generating body 1 to the liquid heating in the heat conduction stock solution cavity 2, and the controller stops sending warning signal. If in the time of predetermineeing, the user does not trigger control switch 31, then driving motor and catch bar among the controller control switch 31 begin to operate, when control switch 31 received the signal of telecommunication of controller promptly, driving motor drove one side removal of catch bar towards spring 9 to make the thrust of the transmission end of catch bar act on spring 9, spring 9 is compressed, thereby makes first contact site and second contact site contact, and then realizes that heat-generating body 1 heats the liquid in heat conduction stock solution cavity 2.

Of course, in other possible embodiments, there are many ways to set the heating element 1 and the heat-conducting liquid storage cavity 2 to be in a bonded state, and as long as the bonding between the heating element 1 and the heat-conducting liquid storage cavity 2 can be achieved, the scope to be protected by the embodiments of the present application is all the scope.

It can be understood that, in this embodiment, when it is necessary to set the heating element 1 and the heat-conducting liquid storage cavity 2 to be in a separated state, the following three ways are also available:

mode one, through the manual regulation mode, through manual pull-up control switch 31 promptly, make the first contact site of heat-generating body 1 remove towards the direction of the second contact site that deviates from heat conduction stock solution cavity 2, spring 9 is stretched to make first contact site and second contact site separation, and then stop heat-generating body 1 to the heating of heat conduction stock solution cavity 2.

In the second mode, by means of an automatic adjustment mode, that is, the power switch is turned off, the controller provided on the steam cleaning device 100 sends an electric signal to the control switch 31, and the driving motor and the pushing rod in the control switch 31 start to operate to stretch the spring 9; specifically, in this embodiment, the output end of the driving motor is connected to the connection end of the push rod, and the transmission end of the push rod is connected to one end of the spring 9 connected to the first contact portion; when control switch 31 received the signal of telecommunication, driving motor drove the catch bar and moves towards the one side that deviates from spring 9 to make the pulling force of the transmission end of catch bar act on spring 9, spring 9 is stretched, thereby makes first contact site and second contact site separation, and then stops heat-generating body 1 to the heating of heat conduction stock solution cavity 2.

In the third mode, the controller disposed on the steam cleaning device 100 sends a warning signal, such as a voice warning or an LED display warning lamp, to the control switch 31 through a manual and automatic combined adjustment mode, that is, the power switch is turned off. The user receives this warning signal, then in the time of predetermineeing, through pulling up control switch 31, makes the first contact site of heat-generating body 1 remove towards the direction of the second contact site that deviates from heat conduction stock solution cavity 2, and spring 9 is stretched to make first contact site and second contact site separation, and then stop heat-generating body 1 to the heating of heat conduction stock solution cavity 2, and the controller stops sending warning signal. However, if the user does not trigger the control switch 31 within the preset time, the controller controls the driving motor and the push rod in the control switch 31 to start to operate, that is, when the control switch 31 receives an electrical signal from the controller, the driving motor drives the push rod to move towards the side away from the spring 9, so that the pulling force of the transmission end of the push rod acts on the spring 9, the spring 9 is stretched, and thus the first contact part and the second contact part are separated, and the heating of the heat-conducting liquid storage cavity 2 by the heating body 1 is stopped.

Of course, in other embodiments, there are many ways to separate the heat-generating body 1 and the heat-conducting liquid storage cavity 2, and the scope of the present application is only to be protected as long as the heat-generating body 1 and the heat-conducting liquid storage cavity 2 can be separated. In this embodiment, the further structure of the attaching/detaching device 32, i.e. the scissors structure, is also used to adjust the distance between the heating element 1 and the heat-conducting liquid storage cavity 2 by adjusting the telescopic state of the scissors structure (not shown). The operation is substantially the same as or similar to the elastic structure and thus will not be described repeatedly.

Taking a buckle structure (not shown) as an example, the buckle structure of the present embodiment includes a buckle position and a buckle body; the buckle body is arranged on a first contact position of the heating body 1, the buckle position is correspondingly arranged on a second contact position of the heat-conducting liquid storage cavity 2, and the buckle position and the buckle body can be buckled at a designated position. Taking a rotating sleeve structure (not shown) as an example, the rotating sleeve structure comprises a support body and a sleeve which can rotate around the support body, a first contact part of the heating body 1 is arranged on the support body, a second contact part of the heat-conducting liquid storage cavity 2 is arranged on the sleeve, and the second contact part is driven to be attached to or separated from the first contact part by rotating the sleeve; for example, when the sleeve is rotated clockwise, the second contact position of the heat-conducting liquid storage cavity 2 can rotate to the fitting position of the first contact position of the heat-generating body 1, so that the heat-generating body 1 heats the heat-conducting liquid storage cavity 2. When anticlockwise rotating the sleeve, the second contact position of the heat-conducting liquid storage cavity 2 can rotate to the separation position of the first contact position of the heating body 1, so that the heating of the heating body 1 to the heat-conducting liquid storage cavity 2 is stopped.

Of course, in other embodiments, the fit/detach device 32 further includes an insulation assembly (not shown) disposed between the first contact location and the second contact location. The insulation assembly may be fiberglass or aerogel blanket, or the like. For example, the thermal shield assembly may be inserted between the first contact point and the second contact point after they are separated by the spring 9. The heat insulation assembly can realize the separation of the first contact part and the second contact part and can also realize the rapid temperature reduction of the heating body 1 and the heat-conducting liquid storage cavity 2, so that the heat-conducting liquid storage cavity 2 does not spray steam any more.

Of course, the structure of the attaching/detaching device 32 is also many, and it is within the scope of the present invention that the first contact portion of the thermal body can be attached to or detached from the second contact portion of the heat-conducting liquid storage cavity 2.

As can be seen from the above, the specific structure of the first contact portion of the heating element 1 and the second contact portion of the heat-conducting liquid storage chamber 2 is different due to the different structure of the attaching/detaching device 32. For example, when the attaching/detaching device 32 is structured as the spring 9, as shown in fig. 3, both the first contact portion and the second contact portion are provided as plane contact surfaces, i.e., surface contact; the planar contact surface allows for an increased area for heating, thereby accelerating the formation of steam. For another example, when the attaching/detaching device 32 has a snap structure, the first contact portion and the second contact portion may be both formed in a corrugated shape or a gear shape, or may be formed in a concave-convex shape or the like. For another example, the first contact portion and the second contact portion are arranged in a way that the pipelines are crossed, similar to the mosquito coil, to form a three-dimensional contact way.

Further, in order to cooperate with the heating element 1 to heat the liquid in the heat-conducting liquid storage cavity 2 to form steam and deliver the steam, in this embodiment, the heat-conducting liquid storage cavity 2 includes a water inlet 21 and an air outlet 22; the inlet 21 is connected upstream of the first pipe 6 and is able to introduce the liquid of the liquid container 4, and the outlet 22 is connected downstream of the first pipe 6 and delivers the formed vapor to the jet assembly 5 for ejection.

In this embodiment, after the heating element 1 heats the liquid in the heat-conducting liquid storage cavity 2 to form steam, the heat-conducting liquid storage cavity 2 will deliver the steam to the air injection assembly 5 for injection. And in order to make the operation of steam spraying controllable, as shown in fig. 1, the air spraying assembly 5 further includes a nozzle 51, a second switch 52, and an air outlet (not shown); specifically, the second switch 52 is connected with the nozzle 51, the jet assembly 5 controls the nozzle 51 to stop jetting steam through the second switch 52, and the jet assembly 5 is connected with the second pipeline 7 through the air outlet; wherein, the air outlet is provided with a pressure relief valve, the second switch 52 is closed, the nozzle 51 of the air injection assembly 5 stops injecting steam, the pressure relief valve of the air outlet is opened, and the residual steam flows back to the liquid containing device 4 through the second pipeline 7 connected with the pressure relief valve of the air outlet; or the air outlet is provided with a first switch (not shown), the first switch and the second switch 52 form a single-pole double-throw switch, the second switch 52 is closed, the nozzle 51 of the air injection assembly 5 stops injecting the steam, the first switch is opened, and the residual steam flows back to the liquid containing device 4 through a second pipeline 7 connected with the first switch of the air outlet.

In the present embodiment, the first pipeline 6 is connected to the second pipeline 7 through a switch device, which may be a pressure relief valve or a first switch, but the embodiment of the switch device is not limited thereto, as long as the on/off between the first pipeline 6 and the second pipeline 7 can be realized, for example, an electromagnetic switch, a manual switch, a valve, etc., and various switches in the prior art can be realized.

Further, in an embodiment of the present embodiment, as shown in fig. 4, fig. 4 is a device for controlling the nozzle 51 to stop spraying steam by the air spraying unit 5, which comprises a second switch 511, an air inlet 512 and an air outlet 513; the air inlet end 512 receives steam in the heat-conducting liquid storage cavity 2 through the downstream of the first pipeline 6, and the air outlet end 513 is connected with the nozzle 51; rotating or pressing the second switch 511 controls the inlet end 512 to stop steam from entering and the outlet end 513 to stop steam from being ejected, thereby causing the nozzle 51 to stop ejecting steam.
