Embodiments of the present invention

[0040] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0041] It should be noted that all directional indications in this embodiment are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0042] In this disclosure, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0043] Furthermore, the use of terms such as "first" and "second" in this disclosure is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this disclosure.

[0044] The applicant of this disclosure discovered that the steam emitted by the cleaning equipment is affected by the airflow driven by the high-speed rotating cleaning brush on the cleaning equipment and by the suction of the fan on the cleaning equipment. As a result, part of the steam emitted is sucked away and cannot reach the surface to be cleaned. Consequently, only a small portion of the steam emitted by the cleaning equipment can reach the surface to be cleaned, resulting in poor cleaning effect of the cleaning equipment.

[0045] Therefore, in related technologies, cleaning equipment suffers from the technical problem of unsatisfactory cleaning results. This disclosure provides a brush head, cleaning equipment, and a cleaning system, which can at least partially solve the technical problem of unsatisfactory cleaning results in cleaning equipment.

[0046] This disclosure is described below with reference to the accompanying drawings and specific embodiments:

[0047] As shown in Figures 1 and 2, the brush head 110 includes a housing 111 and a cleaning section 116 mounted on the housing 111. The cleaning section 116 protrudes at least partially from the housing 111 and is used to clean the surface 2000 to be cleaned. The outer surface of the housing 111 has an air vent 111a. Along the forward direction of the cleaning section 116, the intersection of the axis of the air vent 111a and the surface 2000 to be cleaned is located in front of the cleaning section 116, and the angle α between the axis of the air vent 111a and the surface 2000 to be cleaned located behind the intersection point is set at 5° to 80°.

[0048] When the brush head 110 is running, the cleaning section 116 rotates at high speed. At least a portion of the cleaning section 116 extends out of the housing 111 and is located outside the housing 111, so that the rotating cleaning section 116 can contact the surface 2000 to be cleaned and wipe the surface 2000, thereby cleaning the surface 2000. The outer surface of the housing 111 is provided with an air outlet 111a, which is used to spray steam. The steam sprayed from the air outlet 111a can reach the surface of the object to be cleaned, so that stubborn dirt on the surface of the object to be cleaned is softened, dissolved, and removed by impact, thereby improving the cleaning effect.

[0049] 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 disclosure. 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 impact 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.

[0050] Designing the included angle α to be within the range of 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 dissipation 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 when it reaches it, 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 the steam also possesses 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.

[0051] In some embodiments, the included angle α ranges from 40° to 60°, including 40° and 60°. It is easy to understand that the size of the acute angle affects the steam's trajectory and cleaning effect. The larger the acute angle, the shorter the steam's travel time in the air, the higher its temperature and the greater its impact force when it reaches the surface 2000 to be cleaned, thus more effectively softening, dissolving, and removing dirt. However, the larger the acute angle, the smaller the steam's tendency to move in the direction of the cleaning section 116. The airflow driven by the rotation of the cleaning section 116 and the suction of the fan have a greater impact on the steam, resulting in less steam actually reaching the cleaning surface and a poor cleaning effect. Conversely, the smaller the acute angle, the longer the steam's travel time in the air, and the greater its tendency to move in the direction of the cleaning section 116. Although the steam is less affected by the airflow driven by the rotation of the cleaning section 116 and the suction of the fan, the lower the temperature and the smaller the impact force when the steam reaches the surface 2000 to be cleaned, resulting in a poorer effect in softening, dissolving, and removing dirt, and thus a poorer cleaning effect. Setting the acute angle to a range of 40°~60° ensures that the steam reaches the surface to be cleaned at a high temperature and with a strong impact force. At the same time, it reduces the interference of the airflow driven by the rotation of the cleaning unit 116 and the suction of the fan on the steam, which can effectively soften, dissolve and remove dirt by impact, thereby achieving a highly efficient and ideal cleaning effect.

[0052] In some embodiments, the distance between the vent 111a and the surface 2000 to be cleaned is 8mm to 15mm.

[0053] Maintaining the distance between the air outlet 111a and the surface 2000 to be cleaned within the range of 8mm to 15mm helps shorten the steam's travel time in the air, thereby reducing heat loss during steam movement. This allows the steam to have a greater impact force and maintain a relatively high temperature when it contacts the surface 2000, thus more effectively softening, dissolving, and removing dirt. The 8mm to 15mm range ensures good cleaning results while reducing the risk of debris getting stuck between the air outlet 111a and the surface 2000 due to excessive proximity, thus helping to ensure the continuous and stable operation of the brush head 110.

[0054] As shown in Figures 3 to 6, in some embodiments, the housing 111 also has a steam chamber 111b, and multiple vent holes 111a are provided, all of which are connected to the steam chamber 111b.

[0055] The brush head 110 generates steam via a steam generating unit, which heats water to produce steam. The structure of the steam generating unit varies and is known to those skilled in the art; therefore, it will not be described in detail or limited here. The steam generated by the steam generating unit is transmitted into the steam chamber 110b. Multiple air outlets 111a are provided on the outer surface of the housing 111, each communicating with the steam chamber 111b. These air outlets 111a are spaced apart. The steam chamber 111b transmits steam to each air outlet 111a. The multiple air outlets 111a ensure that the steam is evenly distributed on the surface 2000 to be cleaned, improving cleaning efficiency and effectiveness. The design of multiple air outlets 111a reduces the risk of the entire steam output being blocked due to clogging of a single air outlet 111a. Even if some of the vents 111a become blocked, the remaining vents 111a can still continue to discharge steam, thus ensuring the continuity and stability of steam output and avoiding the problem of reduced cleaning efficiency due to blockage of the vents 111a.

[0056] In some embodiments, a plurality of vent holes 111a are spaced apart along the length of the cleaning section 116. The spaced arrangement of the plurality of vent holes 111a along the length of the cleaning section 116 enables the steam to be evenly distributed on the front side of the cleaning section 116, ensuring the uniformity of cleaning of the cleaning section 116 and improving cleaning efficiency and effectiveness.

[0057] In some embodiments, the outer surface of the housing 111 has a groove 111c, and a vent 111a is disposed within the groove 111c. The groove 111c can protect the vent 111a from direct impacts, reducing the risk of damage to the vent 111a due to external impacts. Additionally, the design of the groove 111c can reduce the adhesion of debris and other contaminants to the vent 111a, lowering the risk of blockage.

[0058] The outer surface of the housing 111 can have only one groove 111c, and multiple vents 111a are located within this groove 111c. However, in this case, the groove 111c is designed to be relatively large, and external obstacles can easily enter the groove 111c and impact the vents 111a.

[0059] Therefore, in some embodiments, the outer surface of the housing 111 has multiple grooves 111c. With this design, multiple vents 111a are respectively arranged in each groove 111c, reducing the number of vents 111a contained in the same groove 111c. Therefore, the size of the groove 111c can be designed to be smaller, making it less likely for external obstacles to enter the groove 111c, thus strengthening the protection of the vents 111a, reducing the probability of the vents 111a being hit by external obstacles, and reducing the risk of damage to the vents 111a due to external impact.

[0060] 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 to the bottom surface 111d and located on the side of the groove 111c. An air vent 111a is disposed 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, with the bottom surface 111d facing the opening of the groove 111c, the side surface 111e connected to the bottom surface 111d and extending to the opening, and the air vent 111a disposed on the bottom surface 111d and / or the side surface 111e. Multiple air vents 111a can be all disposed on the bottom surface 111d, all disposed on the side surface 111e, or partially disposed on the bottom surface 111d and partially disposed on the side surface 111e.

[0061] In some embodiments, the groove 111c has two side surfaces 111e arranged opposite each other along the length of the cleaning section 116; along the length of the cleaning section 116, the side surface 111e near the end of the cleaning section 116 is not perpendicular to the bottom surface 111d. The non-perpendicular arrangement can be an acute angle or an obtuse angle. With this design, the two side surfaces 111e of the groove 111c can prevent steam from continuing to escape outward along the length of the cleaning section 116, which helps to concentrate the steam in the central area, ensuring that the central area is fully moistened and heated, making it easier to remove stubborn stains.

[0062] In some embodiments, the angle between the side surface 111e near the end of the cleaning section 116 and the bottom surface 111d is an obtuse angle.

[0063] In some embodiments, at least one vent 111a is provided on the side 111e near the end of the cleaning section 116.

[0064] In some embodiments, the axis of the air outlet 111a provided on the side 111e near the end of the cleaning section 116 is perpendicular to the side 111e.

[0065] In other words, the side 111e near the end of the cleaning section 116 is inclined towards the centerline of the cleaning section 116 in the longitudinal direction; at least one vent 111a is provided on the side 111e near the end of the cleaning section 116, and the axis of the vent 111a is perpendicular to the side 111e. At least one vent 111a is provided on the side 111e near the end of the cleaning section 116, and the other vents 111a are provided on the bottom surface 111d. With this design, the vent 111a on the side 111e near the end of the cleaning section 116 can spray steam towards the centerline of the cleaning section 116 in the longitudinal direction. During the cleaning process of the cleaning section 116, the middle area often bears the main cleaning task. This design can concentrate more steam in the middle area, ensuring that the middle area is sufficiently moistened and heated, making it easier to remove stubborn stains. In addition, this design can, to some extent, prevent steam from spraying outside the cleaning area of ​​the cleaning section 116, reducing water residue on the surface to be cleaned.

[0066] In some embodiments, the axis of the vent 111a provided on the bottom surface 111e is perpendicular to the bottom surface 111e. This design helps to increase the coverage area of ​​the steam.

[0067] In some embodiments, the outer surface of the housing 111 is provided with two grooves 111c, which are symmetrically arranged along the center line of the cleaning part 116 along its length. Each groove 111c has a bottom surface 111d and two side surfaces 111e, which are arranged opposite to each other along the length of the cleaning part 116. Two vents 111a are provided on the bottom surface 111d. As shown in FIG3, a vent 111a is provided on the left side of the groove 111c on the left side, and a vent 111a is provided on the right side of the groove 111c on the right side.

[0068] In some embodiments, the vent 111a has a connecting section 111f and a jet section 111g that communicate with each other. The connecting section 111f is located between the steam chamber 111b and the jet section 111g. It should be noted that the connecting section 111f communicates with the steam chamber 111b. The connecting section 111f connects the jet section 111g and the steam chamber 111b. Steam in the steam chamber 111b first enters the connecting section 111f, then enters the jet section 111g, and finally exits from the jet section 111g.

[0069] In some embodiments, the diameter of the jet section 111g gradually increases along the direction of steam flow within the jet section 111g.

[0070] 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 emission. 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.

[0071] As shown in Figures 7 and 8, 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.

[0072] 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.

[0073] 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.

[0074] In some embodiments, the cleaning section 116 is cylindrical and the air intake duct 1112 is arc-shaped.

[0075] 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.

[0076] 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.

[0077] As shown in Figure 9, in some embodiments, a partition 1111 is provided on the outer surface of the housing 111, and the partition 1111 is disposed between two adjacent air outlets 111a. The partition 1111 separates the two adjacent air outlets 111a. The partition 1111 can guide the steam to flow along a specific path, thereby more precisely controlling the direction and distribution of the 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 the mutual interference of steam 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.

[0078] In some embodiments, the surfaces of two adjacent partitions 1111 and the outer surface of the housing 111 together form a groove 111c.

[0079] 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.

[0080] In some embodiments, the brush head 110 further includes a motor, and the cleaning part 116 is mounted on the output end of the motor, and the motor drives the cleaning part 116 to rotate.

[0081] In some embodiments, the brush head 110 further includes a roller 117 rotatably connected to the housing 111, the roller 117 being supported on the surface to be cleaned so that the brush head 110 can move.

[0082] In some embodiments, the housing 111 includes a water storage housing 112 and a support housing 113, which are detachably connected. The water storage housing 112 has a liquid storage chamber for storing cleaning fluid or clean water, etc. An air vent 111a is provided on the outer surface of the water storage housing 112. The cleaning part 116 and the roller 117 are both mounted on the support housing 113, which supports the cleaning part 116 and the roller 117.

[0083] In some embodiments, the water storage housing 112 and the support housing 113 are snapped together for easy disassembly by the user. 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.

[0084] In some embodiments, the water storage housing 112 includes a jet nozzle 114 and a clean water tank 115. The clean water tank 115 has a liquid storage cavity. The jet nozzle 114 is detachably connected to the clean water tank 115, and the clean water tank 115 is detachably connected to the support housing 113. The jet nozzle 114 has an air outlet 111a, a steam chamber 111b, a groove 111c, an air inlet 111h, a mounting surface 111i, and an air inlet pipe 1112. With this design, when the air outlet 111a is blocked and cannot be used, the jet nozzle 114 can be disassembled and replaced with a new jet nozzle 114 for user convenience.

[0085] In some embodiments, the brush head 110 further includes a steam generating unit having a liquid inlet and a steam outlet. An air inlet pipe 1112 is connected to the steam outlet. The liquid inlet of the steam generating unit draws liquid from the liquid storage chamber, heats the liquid to generate steam, and transmits the steam to the air inlet pipe 1112, thereby causing the steam to be ejected from the air outlet 111a.

[0086] As shown in Figure 10, based on the same inventive concept, this disclosure also provides a cleaning device 100, including a main body 120 and the aforementioned brush head 110.

[0087] The main body 120 and the housing 111 are connected, and the user can hold the main body 120 to control the direction of the cleaning device 100. Since the cleaning device 100 includes the brush head 110 described above, it naturally has all the beneficial effects of the brush head 110, which will not be elaborated here.

[0088] In some embodiments, the main body 120 includes a support rod 121 and a grip handle 122 disposed on the support rod 121. The support rod 121 is connected to the brush head 110, and the grip handle 122 is provided with buttons, etc. Users can hold the grip handle 122 of the main body 120 to control the direction of the cleaning device 100. Users can also turn the cleaning device 100 on or off, or change the cleaning mode, etc., by pressing the buttons.

[0089] In some embodiments, the main body 120 also includes a wastewater tank 123, which is detachably connected to the support rod 121, and the dirty water generated during the cleaning process can be stored in the wastewater tank 123.

[0090] In some embodiments, the cleaning device 100 is a household floor scrubber, and the cleaning section 116 is the roller brush of the household floor scrubber.

[0091] As shown in Figure 11, based on the same inventive concept, this disclosure also provides a cleaning system 1000, including a cleaning base station 200 and the aforementioned cleaning device 100. The cleaning base station 200 can support the cleaning device 100 and prevent the cleaning device 100 from tipping over.

[0092] In some embodiments, the cleaning base station 200 can power the cleaning device 100 so that the cleaning device 100 can be charged.

[0093] In some embodiments, the cleaning base station 200 includes a blower unit that can blow out cold or hot air to quickly dry the cleaning section 116 of the cleaning device 100.

[0094] This disclosure has at least the following beneficial effects.

[0095] The brush head includes a housing and a cleaning section mounted on the housing. The cleaning section protrudes at least partially from the housing and is used to clean the surface to be cleaned. The outer surface of the housing includes an air outlet. Along the forward direction of the cleaning section, the intersection of the axis of the air outlet and the surface to be cleaned is located in front of the cleaning section, and the angle α between the axis of the air outlet and the surface to be cleaned located behind the intersection is set at 5° to 80°.

[0096] With this design, steam is sprayed onto the front area of ​​the cleaning section, and the direction of steam spraying is not perpendicular to the surface to be cleaned, but rather at an acute angle to the surface. With this design, the steam, after being sprayed from the air outlet, also has a tendency to move towards the direction of the cleaning section. The steam can be sprayed to a position farther away from the cleaning section, reducing the impact of airflow caused by the rotation of the cleaning section and the suction of the fan on the steam. This results in a larger amount of steam actually reaching the surface to be cleaned from the air outlet, improving the cleaning effect of the brush head.

[0097] Designing the steam angle α to be between 5° and 80° helps ensure that the steam maintains sufficient temperature and impact force upon reaching the surface to be cleaned, improving cleaning efficiency and effectiveness. If the angle α is less than 5°, the steam travels through the air for a longer time after exiting the vent, allowing more time to dissipate heat before reaching the surface. This can cause the steam to cool to an unsuitable temperature for softening and dissolving dirt before reaching the surface, thus affecting the cleaning effect. Furthermore, when the angle α is less than 5°, the longer air travel time after exiting the vent results in a weaker impact force on the dirt upon reaching the surface, reducing the steam's ability to directly impact and remove dirt. Conversely, when the angle α is greater than 5°, the steam reaches the surface at a higher temperature, which softens and dissolves the dirt, and the steam also possesses a certain impact force, enabling it to effectively remove dirt to some extent. If the included angle α is greater than 80°, compared to the steam jet direction being perpendicular to the surface to be cleaned, although the steam can reach more of the surface to be cleaned, 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, and the steam cannot effectively cover the surface to be cleaned, leading to uneven cleaning results and making it difficult to achieve a comprehensive cleaning. The cleaning effect remains limited.
