The utility model provides a steam generator, this steam generator include heating body, heating chamber, and the heating chamber both ends are provided with respectively moreover with the water inlet and the gas outlet of heating chamber intercommunication, the heating body is arranged in heating the water that gets into in the heating chamber from the water inlet. When the steam generator is used in an external device, it is installed in the external device in a transverse manner, i.e. the direction of extension or axial direction of the steam generator or heating body is approximately horizontal or arranged at an angle to the horizontal.

Wherein the steam generator of the present disclosure further comprises a scale holding device having an installation position and a removal position with respect to the heating chamber, in particular, when the scale holding device is in the installation position, the scale holding device is located within the heating chamber and is configured to hold at least a portion of the scale generated by heating the water, and when the scale holding device is in the removal position, the scale holding device can be detached from within the heating chamber.

It can be seen that the steam generator of this disclosure can hold at least part of the scale that hot water produced through the scale container in the course of the work, then when the scale volume in the scale container is more, can follow the heating intracavity with the scale container dismantles to the scale in the scale container clears up, then in the steam generator of reinstalling again, or the scale container that also can directly renew.

Because this incrustation scale accommodate device in the steam generator of this disclosure can clean back reuse or change, and then prolonged steam generator's life, reduced steam generator's change frequency to steam generator's use cost has been reduced.

For easy understanding, the specific structure and the operation principle of the steam generator and the cleaning device and the terminal device of the present disclosure will be described in detail with reference to fig. 1 to 10 in conjunction with one embodiment.

As shown in fig. 1 and 2, the present disclosure provides a steam generator 1, and the steam generator 1 may be used in a cleaning device such as a wireless steam floor washer, a wireless steam mop, or various terminal devices such as a wireless eye fumigating device and a wireless massage device, in which steam is required to be generated.

The steam generator 1 comprises a heating body 11, a heating chamber 12, and a water inlet 121 and a gas outlet 122 communicating with the heating chamber 12. Wherein the heating body 11 is configured for heating water entering the heating chamber 12 from the water inlet 121. The water inlet 121 is connected to an external water source, which may be a liquid storage tank of the device itself or other devices capable of supplying water.

Specifically, as shown in fig. 1 and 2, in an embodiment of the present disclosure, the steam generator 1 further includes a housing 14, the heating body 11 includes a heat conducting portion 111 and a heating portion 112, the heating portion 112 is coated on at least a portion of an outer surface of the heat conducting portion 111, a hollow inner cavity of the heat conducting portion 111 is the heating cavity 12, the heat conducting portion 111 is disposed in the inner cavity of the housing 14, and a water injection pipe joint 124 forming a water inlet 121 is disposed at one end of the housing 14. During the operation of the steam generator 1, water enters the heating cavity 12 in the heat conducting portion 111 through the water filling pipe joint 124, and the heating portion 112 heats the heat conducting portion 111 from the outside, thereby heating the water in the heat conducting portion 111.

Wherein, as shown in fig. 2, the steam generator 1 has a first end and a second end opposite to each other along the axial direction of the steam generator 1; the water inlet 121 is arranged at a first end of the heating chamber 12, and the air outlet 122 is arranged at a second end of the heating chamber 12; the heating body 11 may be disposed in a horizontal direction, or may be inclined upward gradually from a first end to a second end as shown in fig. 2, and a heating region 113 is disposed adjacent to the first end of the heating body 11. Since the water inlet 121 is provided at the first end of the heating chamber 12, a position adjacent to the first end of the heating body 11 can be covered with water to form the heating region 113, while a position adjacent to the second end of the heating body 11 is not easily covered with water to form the high temperature region 114. During the use of the steam generator 1, after water enters the heating cavity 12 from the water inlet 121, steam is formed after the heating area 113 is heated, and then the formed steam is discharged from the air outlet 122 after passing through the high temperature area 114.

The steam generator 1 of the present disclosure further comprises a scale holding means 13, the scale holding means 13 having an installation position and a removal position with respect to the heating chamber 12. In particular, as shown in figures 1 and 2, when the scale holding means 13 is in the installed position, the scale holding means 13 is located within the heating chamber 12 and is configured to hold at least part of the scale produced by heating the water. As also shown in fig. 3, when the scale holding means 13 is in the detached position, the scale holding means 13 can be detached from within said heating chamber 12. The first end of the heating chamber 12 is provided with a mounting hole 123 and the scale holding means 13 is configured to protrude into the heating chamber 12 through the mounting hole 123. As shown in fig. 2 and 4, the scale holding means 13 includes a chamber 131 having a scale holding chamber 132, the chamber 131 is drawer-shaped as a whole, and the middle region is the scale holding chamber 132 for holding scale.

Since the water falls from the water inlet 121 into the heating chamber 12 from top to bottom, in order to ensure that the water can contact the heating body 11 located at the bottom of the scale holding device 13 after entering the heating chamber 12 and make part of the water boil in the scale holding chamber 132, the bottom of the chamber 131 is provided with water holes 133 for communicating the scale holding chamber 132 with the heating chamber 12, and the water falling into the heating chamber 12 can cover at least part of the scale holding chamber 132 through the water holes 133. As shown in fig. 2, the heating area 113 partially overlaps the scale bearing chamber 132, and part of the scale can boil in the scale bearing chamber 132, so that part of the scale can be formed on the surface of the scale bearing chamber 132, and part of the scale particles can fall in the scale bearing chamber 132, so that the scale generated by the steam generator can fall into the scale bearing chamber 132 as much as possible.

To further trap a portion of the scale particles in the steam in the scale holding chamber 132, as shown in fig. 2, in one embodiment of the disclosure, the scale holding chamber 131 is at least partially disposed in a position corresponding to the high temperature zone 114 when the scale holding apparatus 13 is in the installed position. Like this, the steam that mixes the scale granule is at the in-process that moves to gas outlet 122, has some scale granules to adhere to in the chamber wall of holding dirty chamber 132 to can reduce the scale content in the follow-up steam, avoid the scale to plug up follow-up structures such as venthole as far as possible.

After the steam generator 1 is operated for a long time, as shown in fig. 3, the user can detach the scale holding means 13 from the heating chamber 12, clean the scale in the scale holding means 13, and then re-install the scale in the steam generator 1; or a new scale holding means 13 can be directly replaced.

In order to mount and dismount the scale accommodating device 13, as shown in fig. 4, the scale accommodating device 13 further includes a mounting portion 136 connected to the cavity 131, and the mounting portion 136 is configured to be hermetically connected to the mounting hole 123, so as to seal the mounting hole 123 and prevent water in the heating chamber 12 from flowing to the outside.

Specifically, in order to connect the mounting portion 136 with the mounting hole 123 in a sealing manner, as shown in fig. 5, in an embodiment of the present disclosure, at least one clamping groove 1241 is formed on a side surface of a first end portion of the steam generator 1, and the clamping groove 1241 includes an outer clamping section 12411 penetrating to the first end surface of the steam generator 1 and extending along an axial direction of the steam generator 1, and an inner clamping section 12412 communicating with the outer clamping section 12411 and extending along a circumferential direction of the steam generator 1; as shown in fig. 4, a clamping protrusion 1361 corresponding to the clamping groove 1241 is disposed on the outer side of the mounting portion 136, and the clamping protrusion 1361 is configured to move along the axial direction of the steam generator 1 to enter the outer clamping section 12411 and then to be rotatably clamped into the inner clamping section 12412 when the scale container 13 enters the mounting position. Among them, as shown in fig. 4 and 5, three sets of the catching grooves 1241 and the catching protrusions 1361 may be provided in one embodiment of the present disclosure, and other numbers of the catching grooves 1241 and the catching protrusions 1361 may be provided in another embodiment of the present disclosure.

During the installation of the scale container 13, the clamping protrusion 1361 enters the outer clamping section 12411 of the clamping groove 1241, and then after reaching the inner clamping section 12412, rotates along the circumferential direction of the steam generator 1 gradually along with the extending direction of the inner clamping section 12412, and then reaches the end of the inner clamping section 12412. When the clamping protrusion 1361 is clamped into the extreme end of the inner clamping section 12412, even if the steam generator 1 is slightly vibrated during operation, the clamping protrusion 1361 is difficult to slide out of the clamping groove 1241, so that the sealing connection between the mounting portion 136 and the mounting hole 123 can be well ensured. When the scale container 13 needs to be removed, the user only needs to rotate the scale container 13 in the reverse direction, and then the scale container 13 can be pulled out of the steam generator 1.

It can be seen that the steam generator 1 of the present disclosure can accommodate at least a portion of the scale generated by heating water during operation by the scale container 13, and then when the amount of scale in the scale container 13 is large, the scale container 13 can be detached from the heating chamber 12, cleaned from the scale container 13, and then installed back into the steam generator 1 again, or a new scale container 13 can be directly replaced.

Because the incrustation scale holding device 13 in the steam generator 1 of the present disclosure can be reused or replaced after cleaning, the service life of the steam generator 1 is prolonged, the replacement frequency of the steam generator 1 is reduced, and thus the use cost of the steam generator 1 is reduced.

In the scale containing device 13 of the present disclosure, as shown in fig. 2, in one embodiment of the present disclosure, the cavity 131 is configured to extend along the axial direction of the heating chamber 12 with a gap between the outer wall of the cavity 131 and the inner wall of the heating chamber 12. Because the cavity 131 extends along the axial direction of the heating cavity 12, a gap is formed between the outer wall of the cavity 131 and the inner wall of the heating cavity 12, and a gap is formed between the cavity 131 and the heating cavity 12, not only can the steam or water be fully contacted with the inner wall of the heating cavity 12 be ensured, but also the direct contact between the cavity 131 and the heating body 11 can be avoided, the heat can be prevented from being directly guided to the cavity 131, and the cavity 131 can not be damaged by heating.

In order to enable the steam generated by the heating zone 113 to flow better, as shown in fig. 2 and 4, in one embodiment of the present disclosure, the top of the cavity 131 is provided with a hollow 134; steam generated by heating water in the dirt bearing cavity 132 is configured to flow through the hollow 134 in the direction of the air outlet 122. Since the specific gravity of the steam is smaller than that of the scale particles, some scale particles will remain in the scale cavity during the steam generated by heating the water in the scale bearing cavity 132 flows through the hollow 134 in the direction of the air outlet 122, so as to prevent the scale particles from depositing on other parts of the steam generator 1 as much as possible.

In order to enable the water to flow to the bottom of the heating chamber 12 more smoothly, as shown in fig. 2, in one embodiment of the present disclosure, the hollow 134 extends to a position corresponding to the water inlet 121, and the water flowing out of the water inlet 121 is configured to flow into the scale bearing chamber 132 through the hollow 134. Thus, the water falling into the heating chamber 12 can flow into the dirt holding chamber 132 through the hollow 134 and then flow into the heating chamber 12 through the water through holes 133.

In order to make the steam in the cavity 131 flow better, as shown in fig. 2 and 4, in an embodiment of the present disclosure, the hollow 134 extends from the first end of the cavity 131 to the second end of the cavity 131, so that the steam in the whole cavity 131 can flow out of the cavity 131 from the hollow 134 above the cavity and move towards the air outlet 122, so that the steam can flow more smoothly, and the steam generation efficiency of the steam generator 1 is improved.

In one embodiment of the present disclosure, as shown in fig. 2 and 4, the second end of the cavity 131 is provided with a filter hole 135, and a part of the steam generated by heating the water is configured to flow out through the filter hole 135. Through set up filter 135 in the second end of cavity 131, can make some steam that adds hot water production flow out through filter 135, and some scale particles wherein can be kept off in dirt-bearing chamber 132 by filter 135 to can make the steam flow in the cavity 131 more smooth, can reduce the incrustation scale content in the follow-up steam as far as possible again.

In order to avoid the filter holes 135 from being blocked too fast, the size of the filter holes 135 can be adjusted as required. In order to maximize the area occupied by the filter holes 135, as shown in fig. 2 and 4, in one embodiment of the present disclosure, the entire filter holes 135 may be funnel-shaped with the tip end facing the second end of the steam generator 1, and in other embodiments of the present disclosure, the entire filter holes 135 may have other shapes.

As shown in FIG. 6, the present disclosure also provides a cleaning apparatus that may be used with cordless steam scrubbers, cordless steam mops, and the like. Wherein, the cleaning device of this disclosure includes aforementioned steam generator 1 and scrubbing brush subassembly 2 at least, and wherein, scrubbing brush subassembly 2 includes the scrubbing brush casing 21 that has accommodation cavity 22, and steam generator 1 sets up in accommodation cavity 22.

Specifically, as shown in fig. 6, a detachable hole 23 for exposing the scale container 13 and a plug 24 for plugging the detachable hole 23 are provided in a side wall of the floor brush housing 21. Through setting up end cap 24, can shelter from incrustation scale accommodate device 13, avoid in cleaning equipment use incrustation scale accommodate device 13 landing from dismouting hole 23, cause hot water or hot steam to flow out from dismouting hole 23, even scald the user's condition and take place.

To further avoid the user from accidentally removing the plug 24 during the use of the cleaning apparatus, in one embodiment of the present disclosure, as shown in fig. 7 and 8, the floor brush assembly 2 further includes a switch valve assembly 25 disposed on the floor brush housing 21, wherein the switch valve assembly 25 locks the plug 24 with the floor brush housing 21 when in a locked state as shown in fig. 7, and unlocks the plug 24 with the floor brush housing 21 when in an unlocked state as shown in fig. 8. When the cleaning device is used, the switch valve assembly 25 is set to be in a locking state by the cleaning device, the plug 24 and the floor brush shell 21 are locked with each other, and a user cannot open the plug 24; after the cleaning device stops working, as shown in fig. 9, the user can press the unlocking button 26 located on the side wall of the floor brush housing 21 to unlock the switch valve assembly 25, so that the user can remove the plug 24 from the floor brush housing 21, then remove the scale container 13, and clean or replace the scale container 13.

Since the scale holding means 13 needs to be cleaned or replaced at regular time, as shown in fig. 10, in one embodiment of the present disclosure, the cleaning apparatus includes a control unit 3 and an alarm unit 4, and the control unit 3 is configured to control the alarm unit 4 to send out a prompt message for dismounting the scale holding means 13 after the steam generator 1 is operated for a predetermined time. The prompt message may be a sound message emitted by the cleaning device or an image or text message displayed on the cleaning device. The user then cleans or replaces the scale holding means 13 after receiving the reminder.

However, since the replacement interval of the scale container 13 is generally long, for example, 100 hours, the operation time of the steam generator 1 is not cleared after the power of the steam generator 1 is turned off, but is continuously accumulated. At least when the user has replaced the completely cleaned or new scale holding means 13, the operating time of the steam generator 1 is cleared and the running time is accumulated again.

Application scenario one

The user opens the switch of the terminal device provided by the disclosure, and after the terminal device is opened, the steam generator and the water pump are controlled to be started. The water in the reservoir is continuously pumped by the water pump to the water inlet 121 of the steam generator 1.

The water falling into the heating chamber 12 can flow into the dirt receiving chamber 132 through the hollow 134 and then flow into the heating chamber 12 through the water through holes 133, and the dirt receiving chamber 132 is partially overlapped with the heating region 113 of the heating body 11, so that part of the water can boil in the dirt receiving chamber 132, and the scale can be formed on the surface of the dirt receiving chamber 132, and part of the scale particles in the steam can also fall into the dirt receiving chamber 132, so that the scale generated by the steam generator 1 can fall into the dirt receiving chamber 132 as much as possible.

And the vapor will travel along the high temperature region 114 toward the outlet 122 after it is formed. In the process that the steam mixed with the scale particles moves from the hollow 134 to the air outlet 122, part of the scale particles are attached to the wall of the scale bearing cavity 132, so that the content of the scale in the subsequent steam can be reduced, and the subsequent structures such as air outlets blocked by the scale can be avoided as much as possible. Part of the steam flows out through the filtering holes 135, and part of the scale particles in the steam can be blocked in the scale bearing cavity 132 by the filtering holes 135, so that the steam in the cavity 131 can flow more smoothly, and the scale content in the subsequent steam can be reduced as much as possible.

After the steam generator 1 works for a long time, the user can make the scale holding device 13 be separated from the heating cavity 12, clean the scale in the scale holding device 13, and then put back into the steam generator 1; or a new scale holding means 13 can be directly replaced.

Because the incrustation scale holding device 13 in the steam generator 1 of the present disclosure can be reused or replaced after cleaning, the service life of the steam generator 1 is prolonged, the replacement frequency of the steam generator 1 is reduced, and thus the use cost of the steam generator 1 is reduced.

Application scenario two

The user opens the switch of the cleaning device provided by the disclosure, and after the cleaning device is opened, the steam generator and the water pump are controlled to be started. The water in the liquid reserve tank is continuously pumped into the water inlet 121 of the steam generator 1 by the water pump, and the steam generator 1 can continuously heat the water into steam.

When the cleaning device is used, the switch valve assembly 25 is set to be in a locking state by the cleaning device, the plug 24 and the floor brush shell 21 are locked with each other, and a user cannot open the plug 24, so that the situation that hot water or hot steam flows out of the dismounting hole 23 and even scalds the user due to the fact that the scale accommodating device 13 slides off the dismounting hole 23 in the using process of the cleaning device is avoided.

And after the steam generator 1 works for a preset time, the control unit can control the alarm unit to send prompt information for disassembling and assembling the scale containing device 13, then a user can close the cleaning equipment and press the unlocking button 26 on the side wall of the floor brush shell 21 to unlock the switch valve assembly 25, so that the user can take down the plug 24 from the floor brush shell 21, then take down the scale containing device 13, and clean or replace the scale containing device 13.
