[0009] In some embodiments, the included angle a is in the range of 40°-60°.

[0010] In some embodiments, the distance between the gas outlet hole and the surface to be cleaned is 8mm-15mm.

[0011] In some embodiments, the shell further has a steam cavity, and the gas outlet hole is a plurality of gas outlet holes, and the plurality of gas outlet holes are in communication with the steam cavity.

[0012] In some embodiments, the outer surface of the shell is provided with a separation part, and the separation part is arranged between two adjacent gas outlet holes.

[0013] In some embodiments, the outer surface of the shell has a groove, and the air outlet hole is arranged in the groove.

[0014] In some embodiments, the outer surface of the shell has a plurality of grooves.

[0015] In some embodiments, the groove has a bottom surface at the bottom of the groove and a side surface connected with the bottom surface and located at the side of the groove; the air outlet hole is arranged on the bottom surface and / or the side surface.

[0016] In some embodiments, the groove has two side surfaces arranged oppositely along the length direction of the cleaning part; the side surface close to the end of the cleaning part is arranged non-perpendicularly to the bottom surface along the length direction of the cleaning part.

[0017] In some embodiments, the included angle between the side surface close to the end of the cleaning part and the bottom surface is obtuse.

[0018] In some embodiments, at least one air outlet hole is arranged on the side surface close to the end of the cleaning part.

[0019] In some embodiments, the axis of the air outlet hole arranged on the side surface close to the end of the cleaning part is arranged perpendicularly to the side surface, or the axis of the air outlet hole arranged on the bottom surface is arranged perpendicularly to the bottom surface.

[0020] In some embodiments, the air outlet hole has a connecting section and a jetting section in communication, and the connecting section is located between the steam cavity and the jetting section.

[0021] In some embodiments, the caliber of the jetting section gradually increases along the direction of steam flow.

[0022] In some embodiments, the shell further has an air inlet hole in communication with the steam cavity, and the steam cavity has a protruding part opposite to the air inlet hole.

[0023] In some embodiments, the shell further has an air inlet pipe in communication with the air inlet hole, and the air inlet pipe is matched with the shape of the cleaning part.

[0024] In some embodiments, the shell has a mounting surface, the air outlet hole is arranged on the mounting surface, and the jetting surface of the air outlet hole is flush with the mounting surface.

[0025] In the second aspect, the embodiments of the present application provide a cleaning device, which comprises a main body and the brush head of the first aspect.

[0026] In the third aspect, the embodiments of the present application provide a cleaning system, which comprises a cleaning base station and the cleaning device of the second aspect.

[0027] The utility model has at least the following beneficial effects:

[0028] The brush head comprises a shell and a cleaning part mounted on the shell. The cleaning part at least partially protrudes outward from the shell and is used for cleaning a surface to be cleaned. The outer surface of the shell has an air outlet hole. In the advancing direction of the cleaning part, the intersection of the axis of the air outlet hole and the surface to be cleaned is located in front of the cleaning part, and the angle a between the axis of the air outlet hole and the surface to be cleaned located behind the intersection is 5-80 degrees.

[0029] In this way, the steam is sprayed in the front side area of the cleaning part, and the spraying direction of the steam is not perpendicular to the surface to be cleaned but at an acute angle with the surface to be cleaned. After the steam is sprayed from the air outlet hole, the steam still has a movement trend towards the advancing direction of the cleaning part. The steam can be sprayed to a position far away from the cleaning part, the influence of the airflow caused by the rotation of the cleaning part and the suction of the fan on the steam is reduced, the steam amount actually reaching the surface to be cleaned after being sprayed from the air outlet hole is increased, and the cleaning effect of the brush head is improved.

[0030] The range of the angle a is designed to be 5-80 degrees, which helps to ensure that the steam maintains sufficient temperature and impact force when reaching the surface to be cleaned, and improves the cleaning efficiency and effect. If the acute angle is less than 5 degrees, the steam has a long time to move in the air after being sprayed from the air outlet hole, and has more time to dissipate heat before reaching the surface to be cleaned, which easily leads to the steam being cooled to a temperature that is not suitable for softening and dissolving before reaching the surface to be cleaned, so that the dirt cannot be softened and dissolved, thereby affecting the cleaning effect. When the acute angle is less than 5 degrees, the steam has a long time to move in the air after being sprayed from the air outlet hole, and the impact force of the steam on the dirt on the surface to be cleaned is weak when the steam reaches the surface to be cleaned, which weakens the ability of the steam to directly impact and strip the dirt. When the acute angle is greater than 5 degrees, the steam is still relatively hot when reaching the surface to be cleaned, which can soften and dissolve the dirt, and the steam also has a certain impact force, which can impact and strip the dirt to a certain extent. If the acute angle is greater than 80 degrees, compared with the case that the spraying direction of the steam is perpendicular to the surface to be cleaned, although more steam can reach the surface to be cleaned, the influence of the airflow caused by the rotation of the cleaning part and the suction of the fan on the steam is still large, which leads to the steam amount actually reaching the surface to be cleaned being still small, the steam cannot effectively cover the surface to be cleaned, the cleaning effect is uneven, and it is difficult to achieve comprehensive cleaning, and the cleaning effect is still limited.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0048] The applicant of the present application finds that the steam sprayed by the cleaning device is affected by the airflow caused by the high-speed rotating cleaning brush on the cleaning device and by the suction of the fan of the cleaning device, so that part of the sprayed steam is sucked away and cannot reach the surface to be cleaned, so that only a small part of the steam sprayed by the cleaning device can reach the surface to be cleaned, resulting in poor cleaning effect of the cleaning device.

[0049] Therefore, in the related art, the cleaning device has the technical problem of poor cleaning effect. The brush head, the cleaning device and the cleaning system provided by the embodiments of the present application can at least solve the technical problem of poor cleaning effect of the cleaning device to a certain extent.

[0050] The present application will be described below in conjunction with the drawings and specific embodiments:

[0051] As shown in Figure 1 and Figure 2 The brush head 110 includes a shell 111 and a cleaning part 116 mounted on the shell 111. The cleaning part 116 at least partially protrudes out of the shell 111 and is used to clean the surface to be cleaned 2000. The outer surface of the shell 111 has a gas outlet hole 111a. Along the advancing direction of the cleaning part 116, the intersection of the axis of the gas outlet hole 111a and the surface to be cleaned 2000 is located in front of the cleaning part 116, and the angle α between the axis of the gas outlet hole 111a and the surface to be cleaned 2000 located behind the intersection is set to be 5°-80°.

[0052] When the brush head 110 is running, the cleaning part 116 rotates at high speed, and at least part of the cleaning part 116 protrudes out of the shell 111 to enable the rotating cleaning part 116 to contact the surface to be cleaned 2000 and wipe the surface to be cleaned 2000, thereby cleaning the surface to be cleaned 2000. The outer surface of the shell 111 is provided with a gas outlet hole 111a for spraying steam. The steam sprayed by the gas outlet hole 111a can reach the surface of the object to be cleaned, so that the stubborn dirt on the surface of the object to be cleaned is softened, dissolved and stripped by impact, thereby improving the cleaning effect.

[0053] The intersection of the axis of the vent 111a and the surface 2000 to be cleaned is located in front of the cleaning section 116. That is to say, the intersection of the steam ejection direction and the surface 2000 to be cleaned is located on the front side of the cleaning section 116, so that the steam is sprayed on the front side of the cleaning section 116. The angle α between the axis of the vent 111a and the surface 2000 to be cleaned behind the intersection point is an acute angle of 5° to 80°, including 5° and 80°. It can be 30°, 45°, 60°, etc., and is not limited in this application. With this design, the steam is sprayed in the front area of ​​the cleaning section 116, and the direction of the steam spray is not perpendicular to the surface to be cleaned 2000, but at an acute angle to the surface to be cleaned 2000. With this design, the steam sprayed out from the air outlet 111a also has a tendency to move towards the direction of the cleaning section 116. The steam can be sprayed to a position far away from the cleaning section 116, reducing the influence of the airflow driven by the rotation of the cleaning section 116 and the suction of the fan on the steam. This results in a larger amount of steam actually reaching the surface to be cleaned 2000 from the air outlet 111a, thus improving the cleaning effect of the brush head 110.

[0054] Designing the included angle α to range from 5° to 80° helps ensure that the steam maintains sufficient temperature and impact force when it reaches the surface 2000 to be cleaned, improving cleaning efficiency and effectiveness. If the acute angle is less than 5°, the steam travels through the air for a longer time after being ejected from the vent 111a, allowing more time for heat loss before reaching the surface 2000. This can cause the steam to cool to an unsuitable temperature for softening and dissolving before reaching the surface, failing to soften and dissolve the dirt and thus affecting the cleaning effect. Furthermore, when the acute angle is less than 5°, the steam travels through the air for a longer time after being ejected from the vent 111a, resulting in a weaker impact force on the dirt on the surface 2000, reducing the steam's ability to directly impact and remove dirt. However, when the acute angle is greater than 5°, the steam is still at a relatively high temperature when it reaches the cleaning surface, capable of softening and dissolving the dirt, and also possessing a certain impact force, which can effectively remove dirt to some extent. If the acute angle is greater than 80°, compared to the steam jet direction being perpendicular to the surface to be cleaned 2000, although the steam can reach more of the surface to be cleaned 2000, the airflow driven by the rotation of the cleaning unit 116 and the suction of the fan still have a significant impact on the steam. This results in a relatively small amount of steam actually reaching the surface to be cleaned 2000, and the steam cannot effectively cover the surface to be cleaned 2000, leading to uneven cleaning results and making it difficult to achieve a comprehensive cleaning. The cleaning effect remains limited.

[0055] In some embodiments, the included angle a is in the range of 40°-60°, inclusive. It is easy to understand that the size of the acute angle affects the movement track of the steam and the cleaning effect. The greater the angle of the acute angle, the shorter the time of the steam moving in the air, the higher the temperature and the greater the impact force of the steam when reaching the cleaning surface 2000, thereby more effectively softening, dissolving and peeling off the dirt. However, the greater the angle of the acute angle, the smaller the movement trend of the steam in the advancing direction of the cleaning part 116, and the greater the influence of the airflow driven by the rotation of the cleaning part 116 and the suction of the fan on the steam, which can result in less steam actually reaching the cleaning surface, and poor cleaning effect. It is easy to understand that the smaller the angle of the acute angle, the longer the time of the steam moving in the air, the greater the movement trend of the steam in the advancing direction of the cleaning part 116, and the smaller the influence of the airflow driven by the rotation of the cleaning part 116 and the suction of the fan on the steam, but the lower the temperature and the smaller the impact force of the steam when reaching the cleaning surface 2000, the worse the effect of softening, dissolving and peeling off the dirt, and the poorer the cleaning effect. By setting the range of the acute angle to 40°-60°, the steam can have a relatively high temperature and a relatively strong impact force when reaching the cleaning surface 2000, while reducing the interference of the airflow driven by the rotation of the cleaning part 116 and the suction of the fan on the steam, which can effectively achieve the softening, dissolving and impact peeling of the dirt, thereby achieving a high-efficiency and ideal cleaning effect.

[0056] In some embodiments, the distance between the air outlet hole 111a and the cleaning surface 2000 is 8-15 mm.

[0057] Controlling the distance between the air outlet hole 111a and the cleaning surface 2000 in the range of 8-15 mm helps to shorten the movement time of the steam in the air, thereby reducing the heat loss during the movement of the steam, so that the steam has a greater impact force and maintains a relatively high temperature when contacting the cleaning surface 2000, thereby more effectively softening, dissolving and peeling off the dirt. The range of 8-15 mm not only ensures a good cleaning effect, but also reduces the risk of garbage being stuck between the air outlet hole 111a and the cleaning surface 2000 due to the air outlet hole 111a being too close to the cleaning surface 2000, which helps to ensure the continuous and stable operation of the brush head 110.

[0058] As shown in FIG. 1, Figures 3 to 6 In some embodiments, the shell 111 also has a steam cavity 111b, and the air outlet hole 111a is a plurality of air outlet holes 111a, and the plurality of air outlet holes 111a are all in communication with the steam cavity 111b.

[0059] The brush head 110 can generate steam through a steam generation unit. The steam generation unit can generate steam by heating clean water. The structure of the steam generation unit is various and known to those skilled in the art, and is not described or limited here. The steam generated by the steam generation unit is transmitted into the steam cavity 110b. The outer surface of the shell 111 is provided with a plurality of air outlets 111a, each of which communicates with the steam cavity 111b. The air outlets 111a are arranged at intervals. The steam cavity 111b transmits steam to each air outlet 111a. The arrangement of a plurality of air outlets 111a allows the steam to be evenly distributed on the surface 2000 to be cleaned, improving cleaning efficiency and effectiveness. The design of a plurality of air outlets 111a reduces the risk of the entire steam output being blocked due to the blockage of a single air outlet 111a. Even if some air outlets 111a are blocked, the remaining air outlets 111a can continue to discharge steam, thereby ensuring the continuity and stability of steam output and avoiding the problem of reduced cleaning efficiency due to the blockage of the air outlet 111a.

[0060] In some embodiments, the plurality of air outlets 111a are arranged at intervals along the length direction of the cleaning portion 116. The arrangement of the plurality of air outlets 111a along the length direction of the cleaning portion 116 allows the steam to be evenly distributed on the front side of the cleaning portion 116, ensuring the uniformity of the cleaning of the cleaning portion 116 and improving the cleaning efficiency and effectiveness.

[0061] In some embodiments, the outer surface of the shell 111 has a groove 111c, and the air outlet 111a is arranged in the groove 111c. The groove 111c can protect the air outlet 111a from direct impact from the outside, reducing the risk of damage to the air outlet 111a due to external impact. In addition, the design of the groove 111c can reduce the adsorption of debris on the air outlet 111a, reducing the risk of blockage of the air outlet 111a.

[0062] The outer surface of the shell 111 can be provided with only one groove 111c, and a plurality of air outlets 111a are located in the groove 111c. However, in this case, the size of the groove 111c is designed to be larger, and obstacles from the outside are easy to enter the groove 111c and impact the air outlet 111a.

[0063] To this end, in some embodiments, the outer surface of the shell 111 has a plurality of grooves 111c. After such design, a plurality of air outlets 111a are arranged in each groove 111c respectively, and the number of air outlets 111a contained in the same groove 111c is reduced, thus the size of the groove 111c can be designed smaller, and thus the external obstacles are less likely to enter the groove 111c, thereby strengthening the protection of the air outlets 111a, reducing the probability of the air outlets 111a being impacted by external obstacles, and reducing the risk of the air outlets 111a being damaged due to external impact.

[0064] In some embodiments, the groove 111c has a bottom surface 111d and a side surface 111e, the bottom surface 111d is located at the bottom of the groove 111c, and the side surface 111e is connected with the bottom surface 111d and located at the side of the groove 111c; the air outlet 111a is arranged on the bottom surface 111d and / or the side surface 111e. That is, the groove 111c has a bottom surface 111d and a side surface 111e, the bottom surface 111d is arranged opposite to the opening of the groove 111c, and the side surface 111e is connected with the bottom surface 111d and extends to the opening; the air outlet 111a is arranged on the bottom surface 111d and / or the side surface 111e. The plurality of air outlets 111a can be arranged on the bottom surface 111d, or can be arranged on the side surface 111e, or can be arranged partly on the bottom surface 111d and partly on the side surface 111e.

[0065] In some embodiments, the groove 111c has two side surfaces 111e arranged opposite along the length direction of the cleaning part 116; along the length direction of the cleaning part 116, the side surface 111e close to the end of the cleaning part 116 is arranged non-perpendicularly with the bottom surface 111d. The non-perpendicular arrangement can be an acute angle arrangement or an obtuse angle arrangement. After such design, the two side surfaces 111e of the groove 111c can block the steam from escaping outward along the length direction of the cleaning part 116, which helps to make the steam converge in the middle area, ensures that the middle area is fully moistened and heated, and makes it easier to remove stubborn stains.

[0066] In some embodiments, the included angle between the side surface 111e close to the end of the cleaning part 116 and the bottom surface 111d is an obtuse angle.

[0067] In some embodiments, at least one air outlet 111a is arranged on the side surface 111e close to the end of the cleaning part 116.

[0068] In some embodiments, the axis of the air outlet 111a arranged on the side surface 111e close to the end of the cleaning part 116 is arranged perpendicularly with the side surface 111e.

[0069] That is, the side surface 111e near the end of the cleaning portion 116 is obliquely arranged towards the lengthwise center line of the cleaning portion 116; at least one air outlet hole 111a is arranged on the side surface 111e near the end of the cleaning portion 116, and the axis of the air outlet hole 111a is arranged perpendicularly to the side surface 111e. At least one air outlet hole 111a is arranged on the side surface 111e near the end of the cleaning portion 116, and other air outlet holes 111a are arranged on the bottom surface 111d. In this way, the air outlet hole 111a on the side surface 111e near the end of the cleaning portion 116 can spray steam towards the lengthwise center line of the cleaning portion 116. During the cleaning process of the cleaning portion 116, the middle region often bears the main cleaning task, and this design can concentrate more steam in the middle region, so as to ensure that the middle region is fully moistened and heated, so that stubborn stains can be more easily removed. In addition, in this way, steam can be prevented from being sprayed outside the cleaning region of the cleaning portion 116 to some extent, and water stains can be reduced on the surface to be cleaned 2000.

[0070] In some embodiments, the axis of the air outlet hole 111a arranged on the bottom surface 111e is arranged perpendicularly to the bottom surface 111e. In this way, the coverage of the steam can be increased.

[0071] In some embodiments, the outer surface of the shell 111 is provided with two grooves 111c, and the two grooves 111c are symmetrically arranged along the lengthwise center line of the cleaning portion 116. Each groove 111c has a bottom surface 111d and two side surfaces 111e, and the two side surfaces 111e are oppositely arranged along the lengthwise direction of the cleaning portion 116. Two air outlet holes 111a are arranged on the bottom surface 111d. As shown in Figure 3 An air outlet hole 111a is arranged on the left side surface of the left groove 111c, and an air outlet hole 111a is arranged on the right side surface of the right groove 111c.

[0072] In some embodiments, the air outlet hole 111a has a connecting section 111f and a jetting section 111g in communication, and the connecting section 111f is located between the steam cavity 111b and the jetting section 111g. It should be noted that the connecting section 111f is in communication with the steam cavity 111b. The connecting section 111f is in communication with the jetting section 111g and the steam cavity 111b, steam in the steam cavity 111b first enters the connecting section 111f, then enters the jetting section 111g, and finally is sprayed from the jetting section 111g.

[0073] In some embodiments, the caliber of the jetting section 111g gradually increases in the direction of the steam flow in the jetting section 111g.

[0074] The gradually increasing diameter of the jet section 111g, along with the direction of steam flow, allows the steam to diffuse within the jet section 111g, increasing the coverage area after steam ejection. This enables the steam to act more widely on the surface 2000 to be cleaned, improving cleaning efficiency and uniformity. Furthermore, the gradually increasing diameter of the jet section 111g helps reduce the accumulation of debris and other impurities in the air outlet 111a, lowering the risk of clogging and facilitating the cleaning and maintenance of the brush head 110.

[0075] like Figure 7 and Figure 8 As shown, in some embodiments, the housing 111 is also provided with an air inlet 111h, which is connected to the steam chamber 111b. The steam chamber 111b has a protrusion 111j, which is disposed opposite to the air inlet 111h.

[0076] The protrusion 111j increases the space near the inlet 111h in the steam chamber 111b. As a result, when steam enters from the inlet 111h, it first enters a larger space within the protrusion 111j. This helps to slow down the steam flow rate and reduce the force of the steam directly impacting the inner wall of the steam chamber 111b, thus acting as a buffer and helping to ensure that the steam is evenly ejected from each outlet 111a.

[0077] In some embodiments, the housing 111 further includes an air inlet pipe 1112 communicating with the air inlet 111h, the air inlet pipe 1112 being adapted to the shape of the cleaning section 116. The air inlet pipe 1112 delivers steam into the air inlet 111h. The adaptation of the shape of the air inlet pipe 1112 to the shape of the cleaning section 116 prevents the air inlet pipe 1112 from interfering with the rotation of the cleaning section 116, ensuring smooth operation of the brush head 110.

[0078] In some embodiments, the cleaning section 116 is cylindrical and the air intake duct 1112 is arc-shaped.

[0079] In some embodiments, the housing 111 has a mounting surface 111i, and an air outlet 111a is disposed on the mounting surface 111i, with the spray surface of the air outlet 111a flush with the mounting surface 111i. The flush design of the spray surface of the air outlet 111a with the mounting surface 111i contributes to a more aesthetically pleasing overall appearance of the brush head 110. Furthermore, the flush design minimizes the corners at the air outlet 111a, reducing the accumulation of dust and dirt and facilitating cleaning and maintenance.

[0080] In the embodiment where the groove 111c is provided, the bottom surface 111d and the side surface 111e of the groove 111c are both mounting surfaces 111i, and the bottom surface 111d and the side surface 111e of the groove 111c are also the ejection surfaces of the air outlet 111a.

The partition 1111 separates two adjacent air outlets 111a. The partition 1111 can guide steam to flow along a specific path, thereby more precisely controlling the direction and distribution of steam and improving the steam's coverage efficiency on the surface 2000 to be cleaned. The partition 1111 also helps to concentrate the steam flow, giving the steam ejected from each air outlet 111a a stronger impact force, more effectively removing dirt, and improving the cleaning effect. In addition, the partition 1111 can reduce steam interference between adjacent air outlets 111a, helping to ensure that each air outlet 111a can work independently and effectively, avoiding uneven steam distribution and improving the uniformity of cleaning.

[0082] In some embodiments, the surfaces of two adjacent partitions 1111 and the outer surface of the housing 111 together form a groove 111c.

[0083] In some embodiments, the partition 1111 is sheet-shaped and disposed along the height direction of the brush head 110. Along the width direction of the brush head 110, the distance between the partition 1111 and the air outlet 111a is 10mm-15mm.

When the liquid such as cleaning fluid or clean water in the water storage housing 112 is depleted, the water storage housing 112 can be removed for replenishment, facilitating the replenishment of liquid.

[0088] In some embodiments, the water storage shell 112 comprises a jet 114 and a clean water tank 115, the clean water tank 115 has a liquid storage cavity, the jet 114 is detachably connected to the clean water tank 115, and the clean water tank 115 is detachably connected to the support shell 113. The jet 114 has a gas outlet hole 111a, a steam cavity 111b, a groove 111c, an air inlet 111h, a mounting surface 111i, and an air inlet pipe 1112. In this way, when the gas outlet hole 111a is blocked and cannot be used, the jet 114 can be detached and replaced with a new jet 114, facilitating user use.

[0089] In some embodiments, the brush head 110 further comprises a steam generating unit having a liquid inlet and a steam outlet. The air inlet pipe 1112 is communicated with the steam outlet. The liquid inlet of the steam generating unit draws liquid from the liquid storage cavity and heats the liquid to generate steam, which is then transmitted to the air inlet pipe 1112, and then the steam is sprayed out of the gas outlet hole 111a.
