Referring to fig. 1, the present application provides a cleaning apparatus 100 comprising: a main body 10, and a steam generator 20 mounted to the main body 10.

In some realizable embodiments of the present application, the cleaning device 100 may be, but is not limited to, a washer, a vacuum cleaner, a sweeping robot, etc., capable of cleaning floors, walls, ceilings, glasses, automobiles, etc.

The main body 10 may include a grip 11, a body 12, and a floor brush 13, in some embodiments, the grip 11 is disposed at an upper end of the body 12, and the floor brush 13 is disposed at a lower end of the body 12.

Specifically, the floor brush 13 may be rotatably coupled to the body 12 to facilitate steering and movement of the floor brush 13 for user manipulation. The floor brush 13 and the body 12 may be rotatably connected by an elastic member, or the floor brush 13 and the body 12 may be hinged, and the embodiment is not limited.

The grip 11 or one side of the body 12 may be further provided with a power cord directly connected to an external power supply terminal for supplying power to the cleaning device 100. Of course, in other alternative embodiments, in order to be out of the power cord and not affect the power supply to the cleaning device 100, the cleaning device 100 may be a wireless cleaning device 100, and specifically, a wireless power supply or a rechargeable battery may be provided in the main body 10, such as the grip 11 or the body 12, and electrically connected to the heat generating material 26 (fig. 2) of the steam generator 20 to supply power to the heat generating material 26.

The steam generator 20 may be provided on the floor brush body, or may be provided on the body 12. Illustratively, the steam generator 20 is disposed on the floor brush body. Referring to fig. 2 to 4, the steam generator 20 has a water inlet 211, a vaporization chamber 212 and an air outlet 213, and the water inlet 211 and the air outlet 213 are both communicated with the vaporization chamber 212, i.e. open to the chamber wall of the vaporization chamber 212. The water inlet 211 is also connected to a water source, which may be an internal water source, but which may of course also be an external water source. In some embodiments of the present application, a clean water tank may be disposed on the body 12, and the water inlet 211 of the steam generator 20 is communicated with the clean water tank. Of course, in other embodiments, the water inlet 211 may also be directly connected to the tap water pipe. Further, a water pump (not shown) is disposed on a communication pipeline between the water inlet 211 and the water source, and the water pump pumps water from the water inlet 211 into the vaporization chamber 212 by increasing water pressure. In addition, the gas outlet 213 may directly face the ground, or a gas channel may be provided on the floor brush body, one end of the gas channel communicates with the gas outlet 213, and the other end faces the ground as a gas injection port, so that the steam generated by the steam generator 20 is guided toward the ground.

In one use mode, after the steam generator 20 is powered on, the vaporization chamber 212 generates high temperature, the water source flows into the vaporization chamber 212 from the water inlet 211 to be vaporized to generate steam, and the steam is sprayed out from the air outlet 213. Meanwhile, the roll brush in the floor brush body rolls, and the steam generator 20 sprays steam to the floor to perform a function of cleaning the floor. The machine body 12 generates negative pressure when working, and dust, sewage and other dirt are sucked by the suction port of the floor brush main body and collected in the recovery barrel, so that the functions of dust absorption and sewage collection are realized through the floor brush main body.

Since the vaporization chamber 212 generally has a relatively large pressure when the steam generator 20 generates steam, the water inlet 211 is easily backwashed when the pressure in the vaporization chamber 212 is relatively large. To prevent the reverse flow, it is conventional to provide a non-return valve at the water inlet 211 of the steam generator 20. However, when the outlet 213 is blocked, for example, the clean water tank of the cleaning device 100 usually uses tap water, the scale carried by the tap water may be accumulated at the outlet 213 of the steam generator 20 due to the pressure, which may cause the outlet 213 to be blocked due to the scale, and at the same time, the inlet 211 is provided with the check valve, which may cause the pressure in the steam generator 20 to be too high, which may cause danger.

In this regard, in the embodiment of the present application, the steam generator 20 includes a housing 21 and a capillary 22, the housing 21 has a vaporization chamber 212 and an air outlet 213 communicating with the vaporization chamber 212, one end of the capillary 22 is connected to the vaporization chamber 212, and the other end of the capillary 22 is used for connecting to a water source.

In the embodiment of the present application, since the diameter of the capillary 22 is small, the flow resistance is large, and the liquid or gas can be prevented from passing through to some extent. Therefore, by arranging the capillary tube 22 on the steam generator 20 to connect with a water source, when the steam generator 20 is in normal operation and the pressure in the vaporization chamber 212 is high, the capillary tube 22 can prevent the water and the steam in the vaporization chamber 212 from flowing backwards, and reduce the interference of the steam pressure on the flow of the water pump. When the vapor generator 20 is in an abnormal condition, for example, the air outlet 213 of the vaporization chamber 212 is blocked, which causes the pressure in the vaporization chamber 212 to be too high, because the capillary 22 is not completely sealed with respect to the check valve, the gas and the liquid in the vaporization chamber 212 can flow to the capillary 22, thereby relieving the pressure in the vaporization chamber 212 to a certain extent and avoiding the danger caused by the too high pressure.

Set up the check valve at water inlet 211 for traditional way, this application embodiment not only can play the check effect of check valve through setting up capillary 22, prevents to appear water countercurrent phenomenon in the vaporization chamber 212 when steam generator 20 normally works, has the release vaporization chamber 212 pressure that the check valve does not possess again, avoids the effect that the dangerous condition takes place. Meanwhile, the capillary tube 22 has a simple structure, is convenient to install, has low cost, and is beneficial to reducing the cost of the whole machine.

The steam generator 20 of the present application will be described in detail with reference to some embodiments.

The shape of the housing 21 includes, but is not limited to, a tube shape, a box shape, a sphere shape, etc., and the housing 21 is exemplarily a tube shape having the water inlet 211 at one end and the air outlet 213 at the other end. The tubular casing 21 is long, and the vaporization chamber 212 formed inside is long, that is, the flow path of water is long from the water inlet 211 to the air outlet 213, so that the water can fully contact with the casing 21 to realize heat exchange, and the steam can be generated by fully vaporizing the water.

The capillary 22 and the housing 21 may be provided separately, and specifically, the housing 21 has a water inlet 211 communicating with the vaporization chamber 212, and the capillary 22 is connected to the water inlet 211. Thus, the water inlet 211 communicates with a water source through the capillary tube 22. In other embodiments of the present application, the capillary 22 and the housing 21 may be integrally formed, and for example, the capillary 22 and the housing 21 are integrally formed by a metal material, so that the capillary 22 itself forms the water inlet 211.

The following description will be given by taking an example in which the capillary 22 and the housing 21 are provided separately.

For convenient processing, water inlet 211 can be seted up greatly, and the pipe diameter of capillary 22 is less, consequently in order to realize the connection of capillary 22 and water inlet 211, and avoid leaking, in this application embodiment, capillary 22 includes water pipe 221 and spacing portion 222, and spacing portion 222 connects the outer peripheral face of water pipe 221 and is cyclic annular setting around the circumference of water pipe 221, and the outer peripheral face of water pipe 221 is all connected to its whole internal perisporium of cyclic annular spacing portion 222. One end of the water passing pipe 221 extends into the water inlet 211, the other end of the water passing pipe 221 is used for connecting a water source, the limiting part 222 is abutted to the outer surface of the shell 21, the limiting part 222 surrounds the water inlet 211 and seals a gap between the water inlet 211 and the water passing pipe 221, and the water leakage phenomenon at the joint of the water inlet 211 and the water passing pipe 221 is avoided.

In some embodiments of the present application, the limiting portion 222 and the water pipe 221 are integrally formed, and the limiting portion 222 and the water pipe 221 do not need to be assembled again, so that the installation steps are simplified, and water leakage caused by a connection gap between the limiting portion 222 and the water pipe 221 is avoided. Illustratively, the stopper 222 is integrally injection-molded with the water passage pipe 221.

Further, the limiting portion 222 includes an annular connecting section 222a and an annular closing section 222b, the annular connecting section 222a surrounds the periphery of the water passing pipe 221, the inner peripheral wall of the annular connecting section 222a is connected with the water passing pipe 221, the outer peripheral wall of the annular connecting section 222a is connected with the annular closing section 222b, the annular closing section 222b is spaced from the outer peripheral surface of the water passing pipe 221, and the annular closing section 222b covers the water inlet 211 and abuts against the outer surface of the housing 21. In this embodiment, the outer diameter of the annular closing section 222b needs to be larger than the aperture of the water inlet 211, so that the water inlet 211 can be covered inside, and the water and the steam in the vaporization chamber 212 are prevented from flowing out from the connection position of the annular closing section 222b and the annular connecting section 222 a. Therefore, by arranging the annular closing section 222b and the water passing pipe 221 at a distance, the water inlet 211 can be surrounded by the annular closing section 222b, the material consumption of the annular closing section 222b is reduced, and the increase of the material cost is controlled.

In other embodiments, the outer diameter of the capillary 22 may be set larger and adapted to the water inlet 211 to achieve a tight fit. Further, a sealant is arranged between the capillary tube 22 and the water inlet 211 to realize sealing, so that water and steam are prevented from escaping from the space between the capillary tube 22 and the water inlet 211.

In order to prevent the capillary 22 from separating from the housing 21, the steam generator 20 further includes a connection hose, which is sleeved on the periphery of the water inlet 211 and covers the capillary 22. To avoid confusion, the following description takes the connection hose at the water inlet 211 as the first hose 23 as an example, specifically, the first hose 23 includes a first large pipe 231 and a first small pipe 232 which are connected, the inner diameter of the first large pipe 231 is larger than the inner diameter of the first small pipe 232, the first large pipe 231 is sleeved on the outer surface of the shell 21, the shell 21 is tubular, the first large pipe 231 is sleeved on one end of the shell 21 where the water inlet 211 is opened and is tightly fitted with the shell 21, and the first large pipe 231 wraps the limiting portion 222; the first small pipe 232 is sleeved on the outer peripheral surface of the water passing pipe 221 and is tightly matched with the water passing pipe 221. In this way, by providing the first hose 23, the capillary 22 and the housing 21 can be connected hermetically, and the water and the vapor in the vaporization chamber 212 are prevented from flowing out from the connection between the capillary 22 and the housing 21. The first hose 23 is made of a high temperature resistant material, such as but not limited to silicone tube, rubber tube, silicone rubber tube.

Further, the air outlet 213 of the housing 21 is provided with a second hose 24, the second hose 24 includes a second large pipe 241 and a second small pipe 242 connected to each other, the inner diameter of the second large pipe 241 is larger than the inner diameter of the second small pipe 242, and the second large pipe 241 is tightly sleeved on the outer surface of the housing 21 and is disposed around the air outlet 213. The second small tube 242 is used to connect other components, such as a gas channel on the floor brush 13.

Further, a spiral passage is formed in the vaporization chamber 212, and the spiral passage extends from the water inlet 211 to the air outlet 213. The spiral channel prolongs the flow path of water, so that the time for the water to reach the air outlet 213 is greatly increased after the water enters from the water inlet 211, the contact time of the water flow and the inner wall of the shell 21 is prolonged, and the water flow is fully heated to realize vaporization to the maximum extent. Meanwhile, the spiral channel can play a role in turbulent flow, and the effect of diffusing water flow is achieved, so that the water flow is fully heated and vaporized.

There are various ways of forming the spiral passage, and one way of realizing the spiral passage is to provide a spring 25 in the vaporization chamber 212 to form the spiral passage. The length and the density of the spring 25 can be arranged according to the requirement, and the flexibility is stronger. Moreover, the spring 25 is hollow (the inside formed by winding the spring 25), so that water can flow through the inside and the periphery of the spring 25, the space occupied by the spring 25 is small, the structure formed by combining the spring 25 and the shell 21 can be arranged more compactly, and the large vaporization cavity 212 ensures that enough space is provided for accommodating water flow for vaporization.

The outer diameter of the spring 25 can be smaller than the inner diameter of the housing 21, so that there is a small gap between the spring 25 and the wall of the vaporization chamber 212, and this gap allows water to pass through, and provides sufficient contact with the housing 21. Meanwhile, a gap is formed between the spring 25 and the shell 21, so that the spring 25 is conveniently installed in the shell 21.

The spiral channel is realized by arranging a screw in the vaporization chamber 212, the screw extends from the water inlet 211 to the air outlet 213, and a spiral channel is formed between the screw and the inner wall of the vaporization chamber 212.

The spiral channel can be realized by integrally forming a thread on the inner wall of the housing 21, i.e., the wall of the vaporization chamber 212.

Further, a water absorbent cotton (not shown) is disposed in the vaporization chamber 212. Because the temperature in the vaporization cavity 212 is high, the water absorption cotton adopts high temperature resistant cotton, so that the water absorption cotton can absorb water and can avoid melting in a high temperature environment. After the water absorption cotton is arranged in the vaporization cavity 212, the water absorption cotton can absorb part of water flowing into the vaporization cavity 212 and occupy part of the space in the vaporization cavity 212, so that the water flowing in the vaporization cavity 212 is reduced, less water in a flowing state is in full contact with the inner wall of the shell 21 to exchange heat, and the vaporization of the part of water in the flowing state is accelerated. Meanwhile, the water adsorbed in the absorbent cotton is heated in the high-temperature vaporization cavity 212 to gradually increase the temperature and is primarily vaporized and released, when the primarily vaporized steam meets the shell 21, the temperature of the shell 21 is higher, so that the steam can be vaporized again to form a larger amount of more delicate steam. Therefore, the arrangement of the water absorption cotton can increase the steam quantity and improve the steam effect under the condition of the same water quantity.

The shape of the absorbent cotton includes but is not limited to a cylinder, a square block, a triangular block, a round table and the like. In a specific embodiment of the application, the cotton that absorbs water is rectangular form, and the cotton that absorbs water of rectangular form extends along casing 21 length direction, therefore the cotton length direction that absorbs water is heated evenly, and the cotton diameter that absorbs water is less, and the cotton inside and outside difference in temperature that absorbs water is little, and whole vaporization is effectual. Optionally, the spring 25 is wound on the absorbent cotton, so that the absorbent cotton is fixed by the spring 25, and the absorbent cotton is prevented from being impacted by water flow or shaking when the whole machine works.

In order to heat the water in the vaporization chamber 212, the steam generator 20 further includes a heating material 26, and the heating material 26 is electrically conducted to heat the water in the vaporization chamber 212. The exothermic material 26 includes, but is not limited to, a heating tube, a heating wire, and the shape of the exothermic material 26 includes, but is not limited to, a spiral shape, a coil shape, a twisted shape, and the like. The heat generating material 26 may be disposed outside the housing 21, for example, on the outer surface of the housing 21, and the heat is transferred into the vaporization chamber 212 by heating the housing 21, so as to indirectly heat and vaporize the water in the vaporization chamber 212. Of course, the heat generating material 26 may be disposed in the housing 21 so that the heat generating material 26 is directly contacted with the water in the vaporization chamber 212 to perform direct heating. When the heat generating material 26 is disposed outside the case 21, the heat generating material 26 is in contact with the outer surface of the case 21 to reduce heat dissipation through air in order to improve heat transfer efficiency.

Illustratively, the heat generating material 26 is a heat generating wire wound around the outer surface of the housing 21, and the housing 21 is a heat conductive housing 21. Through twine the heater on casing 21 surface, direct contact casing 21 can reduce the calorific loss of heater, and the heat that the heater produced more transfers casing 21 to water vaporization. The heating wire is wound on the outer surface of the shell 21 and spirally arranged, optionally, the heating wire extends along the length direction of the shell 21 and spirally arranged, so that all positions on the length direction of the shell 21 are heated by the heating wire, the temperature of each evaporation cavity 212 in the shell 21 is more uniform, and the evaporation effect on water is better. In other embodiments, the heater may also be disposed within the vaporization chamber 212.

The shell 21 adopts the heat-conducting shell 21, and the heat of the heat-generating material 26 can be quickly conducted into the vaporization chamber 212 for vaporizing the water. The heat conducting shell 21 includes, but is not limited to, a metal shell 21 or a quartz shell 21, the metal shell 21 and the quartz shell 21 have high heat conducting efficiency and small heat loss, and heat of the heat generating material 26 can be fully utilized for vaporization. The metal case 21 may be made of any one of stainless steel, copper, aluminum, and the like.

In the embodiment of the present application, by adding the instant heating type steam generator 20 to the cleaning device 100, part of the hot water and part of the steam can be obtained when the water flows through the housing 21, and the heating efficiency is high because the heating material 26 of the instant heating type steam generator 20 is a superconducting wire.
